Treating newly-diagnosed Crohn’s patients with advanced therapy leads to dramatic improvements in outcomes

A large-scale clinical trial of treatment strategies for Crohn’s disease has shown that offering early advanced therapy to all patients straight after diagnosis can drastically improve outcomes, including by reducing the number of people requiring urgent abdominal surgery for treatment of their disease by ten-fold.

The PROFILE trial, led by researchers at the University of Cambridge, involved 386 patients with newly-diagnosed active Crohn’s disease. Recruiting from 40 hospitals across the UK, and supported by the National Institute for Health and Care Research (NIHR) Cambridge Biomedical Research Centre and NIHR Clinical Research Network, it sought to test whether a biomarker – a genetic signature – could predict which patients were at greatest risk of relapses of their condition, and to test two different approaches to treating the disease.

Crohn’s disease is a life-long condition characterised by inflammation of the digestive tract. It affects around one in 350 people in the UK. Even at its mildest, it can cause symptoms that have a major impact on quality of life including: stomach pain, diarrhoea, weight loss and fatigue. Typically patients experience ‘flares’ of inflammation, where their condition worsens for a time, producing more symptoms and progressive bowel damage. As many as one in 10 patients will require urgent abdominal surgery to treat their condition within their first year of diagnosis.

The findings of the PROFILE trial, sponsored by Cambridge University Hospitals (CUH) NHS Foundation Trust and the University of Cambridge, are published today (22 February) in The Lancet Gastroenterology and Hepatology. While the biomarker did not prove useful in selecting treatments for individual patients, a ‘top-down’ treatment strategy involving use of the drug infliximab straight after diagnosis, showed dramatic results.

Infliximab works by blocking a protein found in the body’s immune system, TNF (tumour necrosis factor)-alpha, which plays an important role in inflammation. The drug is administered through regular intravenous infusions directly into the bloodstream or injections under the skin. However, due to historical concerns about cost and side-effects – including an increased risk of infection related to immunosuppression – it is currently only offered when patients experience regular flare-ups that do not respond to less potent treatments.

In the PROFILE trial, patients were assigned at random to one of two treatment groups. Each group was given a different treatment strategy and patients were followed up over the course of a year.

The first group was treated using an ‘accelerated step-up’ approach, which is the conventional treatment strategy used in the UK and across most countries around the world. In this group, patients only started on infliximab if their disease was progressing and not responding to other simpler treatments.

The second group, however, was treated using ‘top-down’ therapy – that is, they were provided with infliximab as soon as possible after their diagnosis, regardless of the severity of their symptoms.

The results were dramatic: 80% of people receiving the top-down therapy had both symptoms and inflammatory markers controlled throughout the course of the entire year compared to only 15% of people receiving the accelerated step-up therapy.

Two-thirds (67%) of patients in the ‘top-down’ group had no ulcers seen on their endoscopy camera test at the end of the trial – something known as endoscopic remission. Endoscopic remission is considered very important as this has been consistently associated with decreased risk of later complications in Crohn’s disease. Most previous clinical trials of therapies have been considered highly successful based on getting 20 to 30% of patients into endoscopic remission.

As well as these findings, patients in the top-down arm also had higher quality of life scores, less use of steroid medication and lower number of hospitalisations.

Strikingly, while around one in 20 patients (5%) in the conventional treatment arm of the trial required urgent abdominal surgery for their Crohn’s disease, only one in 193 (0.5%) receiving the ‘top-down’ therapy required such surgery.

Dr Nuru Noor from the Department of Medicine at the University of Cambridge, one of the study’s lead researchers and first author of the trial, said: “Historically, treatment with an advanced therapy like infliximab within two years of diagnosis has been considered ‘early’ and an ‘accelerated step-up’ approach therefore ‘good enough’. But our findings redefine what should be considered early treatment.

“As soon as a patient is diagnosed with Crohn’s disease, the clock is ticking – and has likely been ticking for some time – in terms of damage happening to the bowel, so there’s a need to start on an advanced therapy such as infliximab as soon as possible. We’ve shown that by treating earlier, we can achieve better outcomes for patients than have previously been reported.”

In fact, say the researchers, the improvements seen among the trial patients receiving ‘top-down’ therapy might be even more stark compared to usual clinical care. Few patients with Crohn’s disease in standard clinical care receive the rapid, ‘accelerated step-up’ approach provided by the trial protocol, and so the benefits of implementing a ‘top-down’ approach in standard clinical care might be even more pronounced.

Crucially, the team found no difference in risk of serious infection between treatment strategies, suggesting that infliximab straight after diagnosis was well tolerated, contrary to previous concerns about its safety. In addition, the cost of the drug, which is now an off-patent, generic and ‘biosimilar’ medicine, has fallen considerably from around £15,000 to around £3,000 per patient per year.

Chief Investigator of the PROFILE trial Professor Miles Parkes, Director of the NIHR Cambridge Biomedical Research Centre, said:  “Up until now, the view has been ‘Why would you use a more expensive treatment strategy and potentially over-treat people if there’s a chance they might do fine anyway?’

“As we’ve shown, and as previous studies have demonstrated, there’s actually a pretty high risk that an individual with Crohn’s disease will experience disease flares and complications even in the first year after diagnosis.

“We now know we can prevent the majority of adverse outcomes, including need for urgent surgery, by providing a treatment strategy that is safe and becoming increasingly affordable. If you take a holistic view of safety, including the need for hospitalisations and urgent surgery, then the safest thing from a patient point of view is to offer ‘top-down’ therapy straight after diagnosis rather than having to wait and use ‘step-up’ treatment.”

The PROFILE team are now actively working on an analysis of the health economics to see whether the benefits of the therapy outweigh its cost.

Professor Parkes added: “It’s not just those five per cent of people requiring surgery that we need to think about. In the ‘step-up’ arm lots of people experienced disease flares without necessarily needing surgery. And every time somebody flares, they require several consultations with specialist doctors and nurses, clinical investigations such as scans and colonoscopies, time off work, time out of education and so on – all leading to major impacts on quality of life for individuals.”

While there are other anti-TNF drugs, such as adalimumab, that work in a similar manner to infliximab and are significantly cheaper, more research is required to understand if it would be as clinically effective.

Ruth Wakeman, Director of Services, Advocacy & Evidence at Crohn’s & Colitis UK said: “Crohn’s Disease affects over 200,000 people in the UK and we know that many of them have symptoms for a long time before they are diagnosed. But diagnosis is not the end of their journey, and the trial and error involved in finding the right treatment can be challenging and distressing.

“This study shows what a dramatic difference early treatment with advanced therapy can make to newly-diagnosed patients. People with Crohn’s don’t want to be stuck in hospital or having surgery, they want to be out in the world, living their lives. Anything that speeds up the path to remission can only be a good thing.”

The research was funded by Wellcome and PredictImmune Ltd and supported by the NIHR Cambridge Biomedical Research Centre.

“If the drug had been offered in the first place, things could have been very different.”

Toby Moore, 28, was just ten years old when it became clear there was something wrong.

“I was at primary school at the time and was getting lots of abdominal pain, lots of going to the toilet and vomiting, low energy levels – I was effectively unable to consume any food or drink without some kind of problem. It was just terrible.”

He visited the GP repeatedly over six months, where among other things he was told it was due to the stress of Year Six exams. He says that for his mother and father, it was probably the most challenging time of their lives as parents.

“I was eventually referred to a paediatric gastroenterologist specialist who within 30 seconds of looking at me said, ‘Right. I think you have Crohn’s disease. I’d like to do these tests,’ and off we went.”

The specialist was correct. He put Toby on an ‘elemental diet’ to manage his condition, which meant that for six weeks he could eat no food or drinks (other than water), only prescription shakes aimed at allowing his digestive system to heal. Toby then had to reintroduce different foods into his diet to see if they could identify what triggered his condition.

Not long afterwards, he had a ‘flare up’, with his symptoms worsening significantly. His local Peterborough hospital was unable to help and so he was referred to the Royal Free Hospital in London. There, his parents had to make the difficult decision of whether he should receive abdominal surgery or go onto biologic medication. They chose the latter, and Toby was put on infliximab.

“If you asked my parents now, they’d call it a light switch drug. I was infused with it on a Thursday and by the Sunday I was a different person. I was eating, drinking, my symptoms had stopped. It was unbelievable. Arguably, if that had been offered in the first place instead of the lighter approach, things could have been very different.”

Toby was on infliximab for several years, but was taken off the drug in late secondary school when he became unwell – “not in a Crohn’s disease way, something else was going on”. He was taken into hospital, where the doctors immediately stopped the treatment, concerned it was a trigger.

Toby was transferred to Addenbrooke’s Hospital, where Dr Miles Parkes took over his treatment. It turned out that Toby also had large vessel vasculitis, another autoimmune condition. Whereas Crohn’s affects your digestive system, this affects blood vessels. It causes the aorta, the main blood vessel in your body, to become narrowed, which causes symptoms including weight loss, unexplained lower back pain and fatigue.

Since then, Toby has been on a number of different biologic treatments, each working for a while before their effects wear off, he experiences another flare up, and is prescribed a different drug. Were it not for the drugs, he says his life would be very different.

“It can be quite debilitating, especially when it’s flaring up, as I’m sure you can imagine, when you have minimal control over certain bodily functions. It’s not the most pleasant.”

His current medication, upadacitinib, involves taking a daily pill. It has helped him manage his condition – flare ups aside – allowing him to live a relatively normal life, hold down a steady job as a chef in a local hospice , close to where he lives, and start a family. But he still has to be very careful.

“Where possible I try to avoid stressful situations that life throws at you. When you live at your mum and dad’s life’s a bit more simple, you’ve got a few less responsibilities, so stress is slightly less, but when you go out into the big wide world – and I’ve got a two-and-a-half year old daughter now – that obviously adds a new dynamic to your life!”

Toby has nothing but praise for the NHS. “They’ve been just phenomenal. Miles is very good at nipping things in the bud straight away. He always actions things, he doesn’t just say, ‘Well, we’ll see how you are in a month’. So it never gets too out of control. My opinion of the NHS is really, really high. They’ve been a lifeline for me.”

Study estimates number of patients for potential new Alzheimer’s disease treatments

Clinical researchers at Cambridgeshire and Peterborough NHS Foundation Trust and South London and Maudsley NHS Foundation Trust have collaborated to model how many patients might receive new treatments for Alzheimer’s disease currently under review.

Using data on eligible patients from both Trusts and scaling up, the team estimate that a maximum of 30,000 people using dementia services around the country would be suitable for these potential treatments and that NHS providers could provide them on a small scale if approved.

This partnership study was supported by the National Institute for Health and Care Research (NIHR) Cambridge and Maudsley Biomedical Research Centres. Their paper has been shared with research and clinical communities in The British Journal of Psychiatry First View while the drugs are being reviewed for regulatory approval in the UK.

Lead author and CPFT Academic Clinical Fellow Dr Axel Laurell said: “‘Last year the first drugs which can slow down the progression of Alzheimer’s disease by targeting brain amyloid were identified as lecanemab and donanemab. This year they are being considered for approval to use in the UK. We wanted to answer a crucial question to help the NHS plan and prepare, by predicting the largest number of people that might receive these drugs if approved based on eligibility criteria from the clinical trials.”

The study team used anonymised research patient databases from Cambridgeshire and Peterborough and South London and Maudsley NHS Foundation Trusts and examined the records of 82,386 people referred to their services. Applying the eligibility criteria to receive these new types of drugs (monoclonal antibodies) for Alzheimer’s, such as diagnosis, stage of disease, other health conditions, brain imaging data and cognitive test results, they predict that 906 people every year could receive these treatments in their services. This model scales up to indicate around 30,000 people using dementia services nationally might use them. 

Dr Ben Underwood, honorary consultant psychiatrist, Research and Development Director at CPFT and study lead said: “Our work, based on real NHS data, suggests that some of the drugs currently being appraised would only be appropriate for a minority of the people we see in clinic. This gives some idea of the potential scale of the challenge of delivering these new treatments in the NHS if they were approved for use. It is important that we continue to research alternatives that can benefit the majority of people living with Alzheimer’s disease. At CPFT, we work to test and bring the latest proven treatments to our patients as a research active Trust, when their safety and clinical efficacy has been assessed and approved for the NHS.”

Dr Ash Venkataraman, NIHR Academic Clinical Lecturer at the Institute of Psychiatry, Psychology and Neuroscience (IoPPN) King’s College London, Speciality Registrar in Old Age Psychiatry at South London and Maudsley NHS Foundation Trust and joint lead author said: “There is understandably a lot of anticipation around the potential of these new Alzheimer’s drugs, but they are both expensive and resource intensive as they require regular infusions and brain scans to check suitability and monitor side effects. As such, it is important to have an accurate estimate of how many people may be suitable for these medications to inform service provision. Our study is the first to do this at a detailed level using diverse patient data across two NHS Trusts.”

The NHS is a world leader in rolling out innovative treatments, including personalised cancer and life-saving gene therapies, and has established a dedicated programme team to prepare the NHS for the potential arrival of new Alzheimer’s treatments. They must first be approved by the Medicines and Healthcare products Regulatory Agency (MHRA) and meet National Institute for Health and Care Excellence (NICE) standards for patient safety, clinical and cost effectiveness.

Cambridge launches clinical trial to test new drug for a rare lung condition

People with pulmonary sarcoidosis are being invited to take part in an international clinical trial at Cambridge University Hospitals.

The RESOLVE-Lung study, supported by the NIHR Cambridge BRC, is evaluating the safety and effectiveness of a new drug, namilumab, in the treatment of pulmonary sarcoidosis.

Sarcoidosis is a rare inflammatory disease which causes granulomas, tiny clumps of immune cells, to form in any organ or tissue. When it occurs in the lungs it is known as pulmonary sarcoidosis.

Although it most commonly affects the lungs, it can also affect the skin, eyes, joints, nervous system, heart and other parts of the body.

The main symptoms of pulmonary sarcoidosis are shortness of breath and a persistent dry cough, and some people experience pain and discomfort in their chest.

Namilumab is a targeted drug designed to block a molecule which promotes inflammation, thought to be involved in granuloma formation and maintenance. Namilumab has not yet been approved by any health authority for any disease or condition.

Participants in the RESOLVE-Lung study will initially receive monthly injections of namilumab or a placebo (a substance with no therapeutic effect) for approximately six months.

After the initial treatment period, all participants will have the option to receive namilumab for another six months, regardless of whether they initially received namilumab or a placebo.

Up to 100 participants will be enrolled at study sites in the United Kingdom, Europe and the United States.

Dr Akhilesh Jha and Dr Theresia Mikolasch, Co-Principal Investigators of the RESOLVE-Lung study at CUH, said: “Sarcoidosis is a disease that can cause inflammation and scarring of the lungs and is often treated with oral steroids, which are known to have significant side effects.

“The RESOLVE-Lung trial aims to investigate a new treatment for sarcoidosis, which will target inflammation more precisely, and if successful, will provide an alternative option to steroids.

“We are grateful if people with sarcoidosis and clinicians looking after them would consider participating in the study.”

Dr Helen Macdonald, Chief Operating Officer at the NIHR Clinical Research Network East of England, said: “It’s only through research that we can find new treatments for managing long-term conditions such as sarcoidosis. We are hugely grateful to people in the East of England who participate in research, including patients, staff and supporters alike.”

Cambridge-led study discovers cause of pregnancy sickness – and potential treatment

A Cambridge-led study supported by the NIHR Cambridge BRC has shown why many women experience nausea and vomiting during pregnancy – and why some women, including the Duchess of Cambridge, become so sick they need to be admitted to hospital.

The culprit is a hormone produced by the fetus – a protein known as GDF15. But how sick the mother feels depends on a combination of how much of the hormone is produced by the fetus and how much exposure the mother had to this hormone before becoming pregnant.

The discovery, published today (13 December 2023) in Nature, points to a potential way to prevent pregnancy sickness by exposing mothers to GDF15 ahead of pregnancy to build up their resilience.

As many as seven in ten pregnancies are affected by nausea and vomiting. In some women – thought to be between one and three in 100 pregnancies – it can be severe, even threatening the life of the fetus and the mother and requiring intravenous fluid replacement to prevent dangerous levels of dehydration. So-called hyperemesis gravidarum is the commonest cause of admission to hospital of women in the first three months of pregnancy.

Although some therapies exist to treat pregnancy sickness and are at least partially effective, widespread ignorance of the disorder compounded by fear of using medication in pregnancy mean that many women with this condition are inadequately treated.

Until recently, the cause of pregnancy sickness was entirely unknown. Recently, some evidence, from biochemical and genetic studies has suggested that it might relate to the production by the placenta of the hormone GDF15, which acts on the mother’s brain to cause her to feel nauseous and vomit.

Now, an international study, involving scientists at the University of Cambridge and researchers in Scotland, the USA and Sri Lanka, has made a major advance in understanding the role of GDF15 in pregnancy sickness, including hyperemesis gravidarum.

The team studied data from women recruited to a number of studies, including at the Rosie Maternity Hospital, part of Cambridge University Hospitals NHS Foundation Trust and Peterborough City Hospital, North West Anglia NHS Foundation Trust. They used a combination of approaches including human genetics, new ways of measuring hormones in pregnant women’s blood.

The researchers showed that the degree of nausea and vomiting that a woman experiences in pregnancy is directly related to both the amount of GDF15 made by the fetal part of placenta and sent into her bloodstream, and how sensitive she is to the nauseating effect of this hormone.

GDF15 is made at low levels in all tissues outside of pregnancy. How sensitive the mother is to the hormone during pregnancy is influenced by how much of it she was exposed to prior to pregnancy – women with normally low levels of GDF15 in blood have a higher risk of developing severe nausea and vomiting in pregnancy.

The team found that a rare genetic variant that puts women at a much greater risk of hyperemesis gravidarum was associated with lower levels of the hormone in the blood and tissues outside of pregnancy. Similarly, women with the inherited blood disorder beta thalassemia, which causes them to have naturally very high levels of GDF15 prior to pregnancy, experience little or no nausea or vomiting.

Professor Sir Steve O Rahilly - Metabolic, Endocrinology and Bone theme lead

Professor Sir Stephen O’Rahilly, scientific director for NIHR Cambridge BRC and co-director of the Wellcome-Medical Research Council Institute of Metabolic Science at the University of Cambridge, who led the collaboration, said: “Most women who become pregnant will experience nausea and sickness at some point, and while this is not pleasant, for some women it can be much worse – they’ll become so sick they require treatment and even hospitalisation.

“We now know why: the baby growing in the womb is producing a hormone at levels the mother is not used to. The more sensitive she is to this hormone, the sicker she will become. Knowing this gives us a clue as to how we might prevent this from happening. It also makes us more confident that preventing GDF15 from accessing its highly specific receptor in the mother’s brain will ultimately form the basis for an effective and safe way of treating this disorder.”

Previous studies of mice exposed to acute, high levels of GDF15 showed signs of loss of appetite, suggesting that they were experiencing nausea, but mice treated with a long-acting form of GDF15 did not show similar behaviour when exposed to acute levels of the hormone. The researchers believe that building up woman’s tolerance to the hormone prior to pregnancy could hold the key to preventing sickness.

Co-author Dr Marlena Fejzo from the Department of Population and Public Health Sciences at the University of Southern California whose team had previously identified the genetic association between GDF15 and hyperemesis gravidarum, has first-hand experience with the condition. “When I was pregnant, I became so ill that I could barely move without being sick. When I tried to find out why, I realized how little was known about my condition, despite pregnancy nausea being very common.

“Hopefully, now that we understand the cause of hyperemesis gravidarum, we’re a step closer to developing effective treatments to stop other mothers going through what I and many other women have experienced.”

The work involved collaboration between scientists at the University of Cambridge, University of Southern California, University of Edinburgh, University of Glasgow and Kelaniya University, Colombo, Sri Lanka. The principal UK funders of the study were the Medical Research Council and Wellcome, with support from the National Institute for Health and Care Research Cambridge Biomedical Research Centre.

Professor Sir Stephen O’Rahilly added: “The support of the NIHR Cambridge Biomedical Research Centre has been critical for the success of this study. The BRC has provided crucial support to our Peptidomics lab to help with our analysis and access to resources like the BRC supported Clinical Biochemistry Assay lab has been essential to deliver this significant breakthrough in understanding hyperemesis gravidarum.

“The BRC provides us with an opportunity to collaborate with expertise from University of Cambridge, Cambridge University Hospitals and other research themes like Professor Gordon Smith, whose samples from his POPS study was vital in our discovery. Without the necessary infrastructure and resources the BRC provides, this study would not have been made possible.”

Professor Miles Parkes, NIHR Cambridge BRC director said: “Its great to see this great breakthrough coming out of the O’Rahilly group. It represents a major step towards better treatment of hyperemesis gravidarum – the most severe and dangerous form of nausea and vomiting in pregnancy that often leads to mums spending long periods in hospital. This work has been supported at each step by the research infrastructure of the NIHR Cambridge Biomedical Research Centre. It emphasises the importance of this NHS-funded infrastructure in delivering major biomedical discoveries of potentially transformational significance with regards to improved health of patients in Cambridge and around the world”

“I was told: ‘Oh, for God’s sake, you’ve just got morning sickness. Pull yourself together.’”

Charlotte Howden considered herself to be in good health prior to getting pregnant in her early thirties. Her pregnancy was proceeding as normal until around week six or seven, when she began feel nauseous. Even then, she didn’t see any reason to be concerned.

“It’s just what we’ve been told to expect in early pregnancy,” she says.

Around a week after the onset of nausea, Charlotte’s condition got worse. Much worse. She found herself being sick as often as 30 times a day, unable to keep food down.

“Every time I tried to eat something, which is obviously what I wanted to do, not only because I felt hungry, but because I was pregnant, that would then instantly make me sick.”

Worse still, she could not keep any fluids down – not even water. Her condition – which she now knows to be hyperemesis gravidarum (HG) – became so bad that even to swallow saliva would make her sick. And a cruel irony is that a common symptom of HG is excessive saliva production.

When Charlotte finally accepted that there was something wrong, that this was not normal pregnancy sickness, she turned to her GP.

“They just said ‘There’s nothing we can do for you. Have you tried ginger? Try and limit your daily activities to best get through this. Try eating a little and often.’”

Returning to the GP, she was offered a urine test for levels of ketones, a chemical produced by the liver (high levels can indicate a serious problem) – the only way, it seemed, that she would be diagnosed with dehydration and referred for treatment. And given that she had not been taking any fluids, this made taking the test incredibly difficult.

“For some reason, it’s only women with HG who are asked to give a sample, when other conditions it is obvious from the way someone looks,” she says.

Charlotte was not referred, but instead her GP prescribed her the first line medication for HG. This did little to help.

“It just makes you comatose, so you sleep the whole day. But I had a full time job, I had responsibilities, financial and otherwise. Sleeping 20 hours a day is not an effective way to live!”

A second ketone test showed that something was obviously wrong. She was told to get to the hospital immediately.

Charlotte was admitted to the early pregnancy ward, which she describes as a traumatic experience.

“You’re with women who are losing their pregnancies, and you’re very much still pregnant. There’s a kind of dismissive behaviour around you of, ‘Oh, for God’s sake, you’ve just got morning sickness. That woman over there has just had a miscarriage. Pull yourself together.’”

After being rehydrated, she was discharged, only to become very sick again and be re-admitted. This cycle repeated, taking its toll.

“Mentally you end up thinking to yourself there is no point in going back to hospital. The definition of insanity is doing the same thing over and over again. You feel completely broken.”

Eventually, she had had enough.

“When I went in again for my third time, I begged [the consultant] to help me because I was very close to making the decision to terminate. She said ‘Look, just give me 24 hours.’”

This time, the consultant gave her medication that finally made her “feel incredible” for 12 hours. Discharged, she would need to get a repeat prescription from her GP – something they were unwilling to do.

“There was a complete disconnect between my GP and the consultant,” she says. Fortunately, Charlotte, rehydrated and re-energised, was ready to fight. She managed to get through to the consultant, who was astounded to hear she was being refused the medication.

“She got on the phone to the GP and I won’t repeat the language she used, but she was very stern, quite rightly, because what’s the point of treating someone in hospital and then just sending them home to come back in a couple of days’ time?”

It took Charlotte until around week 16 of her pregnancy before she was finally on the right treatment to overcome her sickness. She continued taking the medication until around week 37 as she was “petrified to stop taking it”.

In 2016, Charlotte gave birth to a healthy son, Henry. She is determined that no woman should have to go through what she did. In 2020, she presented the world’s first documentary on HG, Sick – The Battle Against HG.

Charlotte became involved with the charity Pregnancy Sickness Support, joining an army of around 600 volunteers who offer peer support and man telephone helplines. She is now its Chief Executive and uses her position to raise awareness of the condition among women and healthcare professionals, including pushing for HG to be taught on all midwifery courses.

Charlotte is hopeful that this new study will lead to a way of treating – and even preventing – HG. She is grateful to Professor O’Rahilly and Dr Fejzo for their work – and in particularly, for taking the condition seriously.

“When you are suffering from a condition and no one can tell you why, you start to think, oh, is it me? Is it something I’ve done?” she says. “I’m so grateful for the dedication of the researchers, because this isn’t a condition that really ever made the headlines until the now Princess of Wales suffered with it. It wasn’t an area of research that people were really interested in. It was just morning sickness – why should we care?”

Research nurse’s poster on complex cancer study wins first prize at public event

“It’s all about collaboration. Collaboration with people across the Cambridge Biomedical Campus was key to getting this study off the ground,” was the first thing Jason Domingo, senior clinical research charge nurse from the NIHR Cambridge Clinical Research Facility (CRF) said on winning the poster competition at the NIHR Cambridge BRC open evening which took place in November.

His poster highlighted the crucial elements of working with multiple hospital teams to set up a complex cancer trial and to try and improve the patient’s research journey.

The poster was one of 14 on display and was voted the winner by members of the public and healthcare professionals.

“This particular cancer trial involved a multi-team effort,” Jason emphasised. “It was a first-in-human trial to be hosted at the NIHR Cambridge CRF and we were only one of nine sites in the world. This treatment-trial was looking at radiation therapy to see if it could help patients with advanced tumours with overexpression of Gastrin-Releasing Peptide Receptor (GRPR), a receptor normally present on some body cells.

“The trial involved giving a radiation infusion to patients, they would then have regular bloods taken and scans to monitor the effects of the treatment. As well as providing radiation treatment, we were dealing with lots of new equipment like a dosimeter and Geiger-Muller contamination monitor that detects and measures radiation that you have been exposed to.

“This meant we had to set up our clinical rooms in a certain way and learn how to monitor radiation levels safely. All the staff had specific radiation safety training and learned how to use the right protective clothing and decontamination procedures.

“In order to set the study up in the CRF, we had to work closely with the hospital’s Cambridge Cancer Trials Centre, Nuclear Medicine, Estates and Facilities, Clinical Trials Pharmacy and Infection Control teams as well as the researchers, it was a team effort. Nuclear Medicine staff provided us with safety training to make sure we could run the study and we also completed risk assessments on members of staff to make sure they were safe to work on the trial.  

“Being a patient-centric trial we then wanted to make sure the patients had a full understanding of what was involved and we wanted to them to have a good experience. The trial involved them staying overnight multiple times and some of the patients participating were coming from outside Cambridge.  

“We then decided to invite eligible patients to come and look around the facility, to see their private en-suite room, meet the staff and have the opportunity to ask any questions.  

“When they joined the trial it went really well. The radiation levels we were dealing with were low and safe for us to work, we were very well monitored by the hospital’s nuclear medicine team. The estates team ensured that trial’s urine samples will not contaminate others’, and infection control team made sure we had the right protective clothing and minimised any risks.

“The patients were comfortable and closely monitored, and they gave some really nice feedback at the end of their visits. They liked the facilities, knowing the hospital was nearby and enjoyed the calming atmosphere of the CRF.

“We knew this trial was going to be a new challenge but we had the support of so many hospital teams. We couldn’t have done it without them and part of this award goes to them as well.”

Jason Domingo, senior clinical research nurse and Caroline McMahon, Patient and Public Involvement Coordinator

Caroline McMahon, patient and public involvement coordinator at the NIHR Cambridge CRF, who worked on the poster with Jason said: “This poster is a prime example of why CRFs exist. We provide a dedicated space with experienced research nurses, facilities, expertise, resources and support staff to run trials like this, and without the help of other teams this study just wouldn’t have happened. Now the staff have this experience it means we can run more of these kind of trials in the future. Cambridge is an amazing place to do research, we’re fortunate that our CRF is based in the heart of the Cambridge Biomedical Campus and can work collaboratively with many different specialities.”

Jason added: “But it’s not just having the facilities and space, it’s the patients who really make a difference. Without our participants we couldn’t do research. I want to thank them all, any contribution whether it’s giving feedback or taking part in a trial makes a huge difference and it’s really valuable to us. Truly, today’s research has the potential to become tomorrow’s care and practice.”

Newborn babies at risk from bacteria commonly carried by mothers

One in 200 newborns is admitted to a neonatal unit with sepsis caused by a bacteria commonly carried by their mothers – much greater than the previous estimate, say Cambridge researchers. The team has developed an ultra-sensitive test capable of better detecting the bacteria, as it is missed in the vast majority of cases.

Streptococcus agalactiae (known as Group B Streptococcus, or GBS) is present in the genital tract in around one in five women. Previous research by the team at the University of Cambridge and Rosie Hospital, Cambridge, identified GBS in the placenta of around 5% of women prior to the onset of labour. Although it can be treated with antibiotics, unless screened, women will not know they are carriers.

GBS can cause sepsis, a life-threatening reaction to an infection, in the newborn. Worldwide, GBS accounts for around 50,000 stillbirths and as many as 100,000 infant deaths per year.

In a study published in Nature Microbiology, the team looked at the link between the presence of GBS in the placenta and the risk of admission of the baby to a neonatal unit. The researchers re-analysed data available from their previous study of 436 infants born at term, confirming their findings in a second cohort of 925 pregnancies.

From their analysis, the researchers estimate that placental GBS was associated with a two- to three-fold increased risk of neonatal unit admission, with one in 200 babies admitted with sepsis associated with GBS – almost 10 times the previous estimate. The clinical assessment of these babies using the current diagnostic testing identified GBS in less than one in five of these cases.

In the USA, all pregnant women are routinely screened for GBS and treated with antibiotics if found to be positive. In the UK, women who test positive for GBS are also treated with antibiotics. However, only a minority of pregnant women are tested for GBS, as the approach in the UK is to obtain samples only from women experiencing complications, or with other risk factors.

There are a number of reasons why women in the UK are not screened, including the fact that detecting GBS in the mother is not always straightforward and only a small minority of babies exposed to the bacteria were thought to become ill. A randomised controlled trial of screening for GBS for treatment with antibiotics is currently underway in the UK.

Dr Francesca Gaccioli from the Department of Obstetrics & Gynaecology at the University of Cambridge said: “In the UK, we’ve traditionally not screened mothers for GBS, but our findings – that significantly more newborns are admitted to the neonatal unit as a result of GBS-related sepsis than was previously thought – profoundly changes the risk/benefit balance of universal screening.”

To improve detection, the researchers have developed an ultrasensitive PCR test, which amplifies tiny amounts of DNA or RNA from a suspected sample to check for the presence of GBS. They have filed a patent with Cambridge Enterprise, the University of Cambridge’s technology transfer arm, for this test.

Professor Gordon Smith, Head of Obstetrics & Gynaecology at the University of Cambridge, said: “Using this new test, we now realise that the clinically detected cases of GBS may represent the tip of the iceberg of complications arising from this infection. We hope that the ultra-sensitive test developed by our team might lead to viable point-of-care testing to inform immediate neonatal care.”

When the researchers analysed serum from the babies’ umbilical cords, they found that over a third showed greatly increased levels of several cytokines – protein messengers release by the immune system. This suggests that a so-called ‘cytokine storm’ – an extreme immune response that causes collateral damage to the host – was behind the increased risk of disease.

Professor Gordon Smith added: “The study required meticulous collection of data and biological samples and involved molecular analysis of more than 1,300 placental samples. These were collected as part of the Pregnancy Outcome Prediction study, funded by the Cambridge NIHR Biomedical Research Centre, which generated a unique and valuable resource to address this and other important questions about what determines healthy and a complex pregnancy.”

The research was funded by the Medical Research Council and supported by the National Institute for Health and Care Research (NIHR) Cambridge Biomedical Research Centre.

Cambridge announced as a major collaborator in new paediatric HealthTech Research Centre

NIHR Cambridge BRC researchers will be supporting a new paediatric research centre hosted by Sheffield, which aims to develop new technologies that improve healthcare in children and young people.  

The Children and Young People HealthTech Research Centre (HRC), led by Sheffield Children’s NHS Foundation Trust, was awarded a £3 million grant from the National Institute for Health and Care Research to identify new ways to improve the management of rare and long-term conditions in babies to young adults.

The award will see Cambridge researchers working in collaboration with Sheffield’s HRC and other expertise across the country to support the development of new medical devices, diagnostics and digital technologies.

Cambridge researchers will focus on the Mind-Body Integration (MBI) theme of the HRC, which is inspired by a growing recognition of the need to jointly consider the physical and psychological needs of children.

Researchers will look at how the interactions of the ‘brain-body’ affect children in order to create new therapies that can target both physical and mental health from birth. They will also look at addressing unmet challenges such as:

  • Supporting the mental health needs of parents of babies who are admitted to neonatal intensive care, 80% of whom go on to suffer mental illness.
  • How to improve mental health outcomes in babies who spent time in neonatal intensive care, who currently experience twice the rate of subsequent psychiatric problems.
  • Optimising treatment and care for children with epilepsy, 30-50% of whom have co-occurring psychiatric problems.
  • Reducing depression in adolescents with diabetes.
  • Responding to the 20% increase in demand for mental health support in under-18s that has occurred since the COVID-19 pandemic.
Dr Kathryn Beardsall

Consultant Neonatologist, Dr Kathryn Beardsall said: “We are looking forward to rising to these challenges by exploiting the potential for novel technologies specifically designed for children and young people to optimise an integrated approach to healthcare, supporting children and their families, and emphasising prevention as well as treatment.”

Professor Paul Fletcher

Professor Paul Fletcher, Bernard Wolfe Professor of Health Neuroscience said: “Digital technologies, including virtual reality, have huge potential in developing our understanding of brain-body integration and, ultimately, in helping to shape interventions that target this crucial point at which physical and mental health interact. It is exciting for us in Cambridge to be part of this ground-breaking enterprise”.

Professor David Rowitch

Professor David Rowitch, Head of Department of Paediatrics and theme lead for the Antenatal, Maternal and Child Health theme at NIHR Cambridge BRC, whose research team will be working with the Sheffield HRC added: “We are pleased we can participate in this national project with our colleagues in Sheffield. Over the last few years there has been a significant rise in children and young people needing support with their physical and mental healthcare and the NIHR Children and Young People HealthTech Research Centre will offer the vital opportunities to develop new treatments to ultimately benefit patients.”

Professor Paul Dimitri, Clinical Director of Innovation and Technology at Sheffield Children’s NHS Foundation Trust, said: “This is an historic milestone positioning Sheffield at the cutting edge of paediatric research and innovation worldwide. The HRC and NCCHT will pioneer the health technologies of tomorrow, delivering dramatic improvements in NHS care that benefit generations to come. We aim to create a lasting legacy for children’s health.”

New HRC for Cambridge

As part of the announcement from the NIHR, Cambridge has been selected to host another arm of the HRC where they will be leading on new ways to improve the experiences of people affected with brain and spinal injuries.

The new Brain and Spine Injury HRC, based at Cambridge University Hospitals, received nearly £3 million in mid-November. Researchers will be collaborating with other teams across England and will focus on five clinical themes. This new HRC will be led by NIHR Cambridge BRC researcher and neurosurgeon, Professor Peter Hutchinson and academic neurosurgeon, Dr Alexis Joannides.

Dr Joannides said: “The new HRC will enable us to build on the Brain MIC’s achievements and work effectively with inventors, academics, and clinicians within the UK and beyond to identify, evaluate, and implement meaningful solutions to improve the lives of people affected by brain injury.”

Professor Hutchinson added: “This funding from the National Institute for Health and Care Research will make a major contribution to the outcome of patients with brain and spine injury. Engaging patients and the public will help us to identify areas of unmet need and working with industry will facilitate the development of new devices and treatment.”

About HRC

From 1 April 2023 the NIHR will launch 14 new HRCs to work to develop new and improved treatments and enable people to better monitor their health, diagnose

ill health sooner and improve management of conditions including cancer, dementia,

cardiovascular and respiratory disease.

The HRCs will also work with companies to develop and test products to support rehabilitation and help those with social care needs to maintain their independence. They will work closely with carers, patients and users at all stages.

Each HRC will be hosted by an NHS organisation in England, bringing industry, academia and the health and care system together. The HRCs will drive innovation and efficiency, bringing new technologies to those who need them most, support the health and care workforce to reduce workload, and help alleviate pressures on the health and care system.

The HRCs will keep the UK at the forefront of research and the place companies want to come to in order to invest in the development of health technologies.

Lab-grown ‘small blood vessels’ point to potential treatment for major cause of stroke and vascular dementia

Cambridge scientists have grown small blood vessel-like models in the lab and used them to show how damage to the scaffolding that support these vessels can cause them to leak, leading to conditions such as vascular dementia and stroke.

The study, published today in Stem Cell Reports, also identifies a drug target to ‘plug’ these leaks and prevent so-called small vessel disease in the brain.

Cerebral small vessel disease (SVD) is a leading cause of age-related cognitive decline and contributes to almost half (45%) of dementia cases worldwide. It is also responsible for one in five (20%) of ischemic strokes, the most common type of stroke, where a blood clot prevents the flow of blood and oxygen to the brain.

The majority of cases of SVD are associated with conditions such as hypertension and type 2 diabetes, and tend to affect people in their middle age. However, there are some rare, inherited forms of the disease that can strike people at a younger age, often in their mid-thirties. Both the inherited and ‘spontaneous’ forms of the disease share similar characteristics.

Scientists at the Victor Phillip Dahdaleh Heart and Lung Research Institute, University of Cambridge, used cells taken from skin biopsies of patients with one of these rare forms of SVD, which caused by a mutation in a gene called COL4.

By reprogramming the skin cells, they were able to create induced pluripotent stem cells – cells that have the capacity to develop into almost any type of cell within the body. The team then used these stem cells to generate cells of the brain blood vessels and create a model of the disease that mimics the defect seen in patients’ brain vessels.

Dr Alessandra Granata from the Department of Clinical Neurosciences at Cambridge, who led the study, said: “Despite the number of people affected worldwide by small vessel disease, we have little in the way of treatments because we don’t fully understand what damages the blood vessels and causes the disease. Most of what we know about the underlying causes tends to come from animal studies, but they are limited in what they can tell us.

“That’s why we turned to stem cells to generate cells of the brain blood vessels and create a disease model ‘in a dish’ that mimics what we see in patients.”

Our blood vessels are built around a type of scaffolding known as an extracellular matrix, a net-like structure that lines and supports the small blood vessels in the brain. The COL4 gene is important for the health of this matrix.

In their disease model, the team found that the extracellular matrix is disrupted, particularly at its so-called ‘tight junctions’, which ‘zip’ cells together. This leads to the small blood vessels becoming leaky – a key characteristic seen in SVD, where blood leaks out of the vessels and into the brain.

The researchers identified a class of molecules called metalloproteinases (MMPs) that play a key role in this damage. Ordinarily, MMPs are important for maintaining the extracellular matrix, but if too many of them are produced, they can damage the structure – similar to the how in The Sorcerer’s Apprentice, a single broom can help mop the floor, but too many wreak havoc.

When the team treated the blood vessels with drugs that inhibit MMPs – an antibiotic and anti-cancer drug – they found that these reversed the damage and stopped the leakage.

Dr Granata added: “These particular drugs come with potentially significant side effects so wouldn’t in themselves be viable to treat small vessel disease. But they show that in theory, targeting MMPs could stop the disease. Our model could be scaled up relatively easily to test the viability of future potential drugs.”

Professor Martin Bennett NIHR Cambridge BRC theme lead for Cardiovascular and Respiratory said: “Cerebral small vessel disease (SVD) is both the commonest cause of vascular dementia and a major cause of stroke, and a major focus of experimental studies in the Cambridge Cardiorespiratory BRC theme. This study provides an important model to identify the mechanisms underlying some genetic forms of SVD, and potential targets and drugs to prevent cerebral SVD.”

The study was funded by the Stroke Association, British Heart Foundation and Alzheimer’s Society, with support from the NIHR Cambridge Biomedical Research Centre and the European Union’s Horizon 2020 Programme.

Commercial Research update

From Mid-October as part of work to improve the set-up of commercial studies in the UK, local contract negotiation is changing in Stage 2 of the National Contract Value Review (NCVR) which was implemented in response to Lord O’Shaughnessy’s independent review of commercial clinical trials

What is changing?

For all studies submitted from Sunday 1 October 2023:

  • Regulatory and costings submissions will be made at the same time
  • The budget will be shared with the lead applicant (lead NHS site) for national costing. This finance schedule will be put into a new template contract appendix, to be shared with sites
  • There is no local site budget negotiation as the financial appendix is mandated for use, unmodified.
  • From 18 October, any contract not already agreed will need to follow NCVR stage 2.
  • The aim is to speed up commercial trial setup so sites can concentrate on assessing resource to provide capacity and capability to deliver the trial.
  • Further information available here.  

Which studies are affected?

All commercial contract research to take place in the NHS across the UK is planned to be in scope of NCVR. There are some exceptions for stage two: phase I-IIa, advanced therapy medicinal product (ATMP) studies and studies carried out in independent contractor primary care.

Studies excluded from stage two in the NCVR process will be included as soon as possible.

World-first trial to provide hearing for children with rare type of genetic hearing loss launches in Cambridge

Addenbrooke’s Hospital in Cambridge is participating in a world-first trial to see whether gene therapy can provide hearing for children with severe to profound hearing loss due to a rare genetic condition.

The trial supported by the NIHR Cambridge BRC and NIHR Cambridge Clinical Research Facility, aims to show whether gene therapy can provide hearing for children born with hearing loss due to auditory neuropathy, a condition caused by the disruption of nerve impulses travelling from the inner ear to the brain.

Up to 18 children under the age of 18 years from three participating countries – the UK, Spain and the USA – will be included in the trial and followed up for five years to see the extent to which their hearing improves.

Auditory neuropathy can be due to a variation in a single gene – known as the OTOF gene – which produces a protein called otoferlin.  This protein typically allows the inner hair cells in the ear to communicate with the hearing nerve.  Mutations in the OTOF gene can be identified by standard NHS genetic testing. 

About 20,000 people across the US and EU5 (UK, Germany, France, Spain and Italy) are thought to have auditory neuropathy due to OTOF mutations.  Children with profound hearing loss face barriers developing communication skills and may miss developmental milestones if the right support is not provided from the start.

Professor Manohar Bance

Professor Manohar Bance, pictured left, an ear surgeon at Cambridge University Hospitals NHS Foundation Trust, and the chief investigator for the trial said: “Children with a variation in the OTOF gene are born with severe to profound hearing loss, but they often pass the new-born hearing screening so everyone thinks they can hear.  The hair cells are working, but they are not talking to the nerve.

“Gene therapy for otoferlin deficiency is the right starting point for young children because it’s among – if not the most – simple approaches for treating hearing loss; everything else should be intact and working normally.  Although experimental, the therapy could also potentially result in better quality hearing compared to cochlear implants.  But we have a short time frame to intervene because the young brain is developing so fast.” 

Intervening later in life becomes less effective as children may never fully form the ability to process the sounds of speech.  If successful for OTOF related hearing loss, gene therapy treatments could be extended to include people with hearing loss due to other more common genetic conditions.  

“It’s really important that we get the first gene therapy treatment right because it will allow us to proceed to treating other genetic conditions,” added Professor Bance.

Gene therapy aims to deliver a working copy of the faulty OTOF gene using a modified, non-pathogenic virus.  It will be delivered via an injection into the cochlea during surgery under general anesthesia. The procedure is similar to cochlear implant surgery, the current standard of care for OTOF related hearing loss.

The trial will consist of three parts, which must be done in order, with children receiving:

  1. A starting dose of gene therapy (DB-OTO) in one ear only.
  2. A higher dose of gene therapy in one ear only, following proven safety of the starting dose.
  3. Gene therapy in both ears with the optimal dose selected after ensuring the safety and effectiveness of DB-OTO in parts 1 and 2.

If the gene therapy is not effective for a child 6 months after treatment, the family can choose to receive a cochlear implant in the treated ear(s).

Ralph Holme, Director of Research and Insight at RNID said:“At RNID we are committed to a future where effective treatments for hearing loss are available for those who need and want them. Gene therapies have the potential to offer long lasting and permanent treatments for hearing loss, rather than merely managing the symptoms as hearing aids do. We welcome this pioneering trial, which we hope will lead to a treatment for children with OTOF related hearing loss and pave the way towards treatments for other genetic conditions.”

Martin McLean, Senior Policy Advisor at the National Deaf Children’s Society, said: “This is a significant development that will be of great interest to families of deaf children whose deafness is caused by a variation in the OTOF gene. The trial will help us to understand more about the effectiveness of gene therapy in improving hearing where deafness has a specific genetic cause.

“While some families will welcome being able to access this trial, it should be emphasised that with the right support from the start, deafness is not a barrier to achievement or happiness. Our role is to support families to make informed choices on whether they want to take up new treatments like this one which have the potential to mitigate the challenges their child might face.”

The trial is sponsored by Decibel Therapeutics, a Boston, US-based company specialising in gene therapies for hearing and balance disorders. DB-OTO is being developed by Decibel Therapeutics in collaboration with Regeneron Pharmaceuticals, Inc. It is supported by the National Institute for Health and Care Research (NIHR) Cambridge Clinical Research Facility and NIHR Cambridge Biomedical Research Centre.

Professor Bance also runs a multidisciplinary genetic hearing loss clinic to help improve the treatment and care of children with hearing disorders. These are examples of services that could be offered at the new Cambridge Children’s Hospital currently in planning.

All clinical trials that take place at Cambridge University Hospitals NHS Foundation Trust (CUHFT) are independently assessed for safety and quality by the Health Research Authority and Research Ethics Committee and complete the required legal and regulatory approvals before CUHFT agrees to participate. A team at the hospital has reviewed the safety protocols and all the necessary information; the trial will be performed and monitored by an experienced team of doctors, nurses and clinical support staff. All participating families give informed consent before treatment.

Obesity accelerates loss of COVID-19 vaccination immunity, study finds

A new study led by scientists at the Universities of Cambridge and Edinburgh has found the protection offered by COVID-19 vaccination declines more rapidly in people with severe obesity than in those with normal weight. It suggests that people with obesity are likely to need more frequent booster doses to maintain their immunity.

Clinical trials have shown that COVID-19 vaccines are highly effective at reducing symptoms, hospitalisation and deaths caused by the virus, including for people with obesity. Previous studies have suggested that antibody levels may be lower in vaccinated people who have obesity and that they may remain at higher risk of severe disease than vaccinated people with normal weight. The reasons for this have, however, remained unclear.

The study supported by NIHR’s Cambridge BRC, BioResource and Cambridge CRF, shows that the ability of antibodies to neutralise the virus declines faster in vaccinated people who have obesity. The findings have important implications for vaccine prioritisation policies around the world.

During the pandemic, people with obesity were more likely to be hospitalised, require ventilators and to die from COVID-19. In this study, the researchers set out to investigate how far two of the most extensively used vaccines protect people with obesity compared to those with a normal weight, over time.

A team from the University of Edinburgh, led by Professor Sir Aziz Sheikh, looked at real-time data tracking the health of 3.5 million people in the Scottish population as part of the EAVE II study. They looked at hospitalisation and mortality from COVID-19 in adults who received two doses of Covid-19 vaccine (either Pfizer-BioNTech BNT162b2 mRNA or AstraZeneca ChAdOx1).

They found that people with severe obesity (a BMI greater than 40 kg/m2) had a 76% higher risk of severe COVID-19 outcomes, compared to those with a normal BMI. A modest increase in risk was also seen in people with obesity (30-39.9kg/m2), which affects a quarter of the UK population, and those who were underweight. ‘Break-through infections’ after the second vaccine dose also led to hospitalisation and death sooner (from 10 weeks) among people with severe obesity, and among people with obesity (after 15 weeks), than among individuals with normal weight (after 20 weeks).

Professor Sir Aziz Sheikh said: “Our findings demonstrate that protection gained through COVID-19 vaccination drops off faster for people with severe obesity than those with a normal body mass index. Using large-scale data assets such as the EAVE II Platform in Scotland have enabled us to generate important and timely insights that enable improvements to the delivery of COVID-19 vaccine schedules in a post-pandemic UK.”

The University of Cambridge team – jointly led by Dr James Thaventhiran, from the MRC Toxicology Unit and Professor Sadaf Farooqi from the Wellcome-MRC Institute of Metabolic Science and NIHR Cambridge BRC theme lead for Nutrition, Obesity, Metabolism and Endocrinology – studied people with severe obesity attending Addenbrooke’s Hospital in Cambridge, and compared the number and function of immune cells in their blood to those of people of normal weight.

They studied people six months after their second vaccine dose and then looked at the response to a third “booster” vaccine dose over time. The Cambridge researchers found that six months after a second vaccine dose, people with severe obesity had similar levels of antibodies to the COVID-19 virus as those with a normal weight.

But the ability of those antibodies to work efficiently to fight against the virus (known as ‘neutralisation capacity’) was reduced in people with obesity. 55% of individuals with severe obesity were found to have unquantifiable or undetectable ‘neutralising capacity’ compared to 12% of people with normal BMI.

“This study further emphasises that obesity alters the vaccine response and also impacts on the risk of infection,” said Dr Agatha van der Klaauw from the Wellcome-MRC Institute of Metabolic Science and first author of the paper. “We urgently need to understand how to restore immune function and minimise these health risks.”

The researchers found that antibodies produced by people with severe obesity were less effective at neutralising the SARS-CoV-2 virus, potentially because the antibodies were not able to bind to the virus with the same strength.

When given a third (booster) dose of a COVID-19 vaccine, the ability of the antibodies to neutralise the virus was restored in both the normal weight and severely obese groups. But the researchers found that immunity again declined more rapidly in people with severe obesity, putting them at greater risk of infection with time.

Dr James Thaventhiran, a Group Leader from the MRC Toxicology Unit in Cambridge and co-lead author of the SCORPIO study said: “It is promising to see that booster vaccines restore the effectiveness of antibodies for people with severe obesity, but it is concerning that their levels decrease more quickly, after just 15 weeks. This shows that the vaccines work as well in people with obesity, but the protection doesn’t last as long.”

Professor Sadaf Farooqi from the Wellcome-MRC Institute of Metabolic Science and co-lead author of the SCORPIO study said: “More frequent booster doses are likely to be needed to maintain protection against COVID-19 in people with obesity. Because of the high prevalence of obesity across the globe, this poses a major challenge for health services”.

New study recommends replacing skull section after brain bleed treatment

A new trial supported by NIHR Cambridge BRC has found – where possible – surgeons should replace the removed section of the skull following surgery to treat a form of brain bleed. Researchers say the approach will save patients undergoing skull reconstruction further down the line.

NIHR funded and supported the RESCUE-ASDH study. The international randomised trial involved 40 centres in 11 countries and 450 patients took part. The results published at the annual meeting of the American Association of Neurological Surgeons and in the New England Journal of Medicine.

One of the life-threatening results of head injury is acute subdural haematoma – a bleed occurring between the brain and skull. It can lead to the build-up of pressure. These bleeds need surgery to stem the blood flow, remove the blood clot and relieve the pressure.

There are two approaches to such surgery. The first is a decompressive craniectomy – involving leaving a section of the skull out – which can be as large as 13cm in length. This protects the patient from brain swelling, often seen with this injury. Typically the missing skull needs reconstruction. Some treatment centres replace the patient’s own bone several months after surgery. In others, they use a manufactured plate.

The second approach is a craniotomy. The skull section is replaced after the bleed is stemmed and the blood clot removed. This approach prevents the need for a skull reconstruction further down the line.

To date there was little conclusive evidence and no accepted criteria for which approach to use. Researchers at the University of Cambridge and Cambridge University Hospitals NHS Foundation Trust launched RESCUE-ASDH to answer this question. Patients were randomly assigned to undergo craniotomy or decompressive craniectomy.

A total of 228 patients underwent craniotomy and 222 decompressive craniectomy. Researchers assessed the outcomes for these patients and their quality of life up to a year after surgery.

Patients in both groups had similar disability-related and quality-of-life outcomes at 12 months post-surgery. There was a trend towards better outcomes with craniotomy.

Around one in four patients (25.6%) in the craniotomy group and one in five (19.9%) in the craniectomy group had a good recovery.

Around one in three patients in both groups (30.2% craniotomy group and 32.2% craniectomy group died within the first 12 months following surgery. 

14.6% of the craniotomy group and 6.9% of the craniectomy group required additional cranial surgery within two weeks after randomisation. However, this was balanced due to fewer people in the first group experienced wound complications (3.9% compared to 12.2%).

The trial’s Chief Investigator Peter Hutchinson, Professor of Neurosurgery at Cambridge, said: “RESCUE-ASDH is the first multicentre study to address a very common clinical question: which technique is optimal for removing an acute subdural haematoma – a craniotomy or a decompressive craniectomy?

 “This was a large trial and the results convincingly show that there is no statistical difference in the 12 month disability-related and quality of life outcomes between the two techniques.”

Co-chief investigator Professor Angelos Kolias, Consultant Neurosurgeon at Cambridge, said: “Based on the trial findings, we recommend that after removing the blood clot, if the bone flap can be replaced without compression of the brain, surgeons should do so, rather than performing a pre-emptive decompressive craniectomy.

 “This approach will save patients from having to undergo a skull reconstruction, which carries the risk of complications and additional healthcare costs, further down the line.”

Professor Andrew Farmer, Director of NIHR’s Health Technology Assessment (HTA) Programme, which funded the study, said: “The findings of this world-leading trial provide important evidence which will improve the way patients with head injuries are treated. 

“High quality, independently funded research like this is vital in providing evidence to improve health and social care practice and treatments. Research is crucial in informing those who plan and provide care.” 

The NIHR Global Health Research Group on Acquired Brain and Spine Injury and the NIHR Clinical Research Network (CRN) supported the study.

The CENTER-TBI project of the European Brain Injury Consortium, and the Royal College of Surgeons of England Clinical Research Initiative supported it too.

Volunteers needed for new needle-free coronavirus vaccine at CRF

Recruitment is underway in Cambridge for volunteers to take part in clinical trials of a revolutionary new needle-free vaccine to protect against COVID-19.

The vaccine – known as DIOS-CoVax – has been developed by Professor Jonathan Heeney at the University of Cambridge and spin-out company DIOSynVax. It is envisaged as a booster targeting COVID-19 virus variants and relatives that threaten future coronavirus pandemics.

This next generation vaccine is administered through a needle-free ‘injection’ – a blast of air that delivers it into the skin. It has already been part of safety trials conducted at the NIHR Southampton Clinical Research Facility, but now recruitment is being expanded and will take place at the NIHR Cambridge Clinical Research Facility.

Professor Heeney said: “We’re excited to be bringing our vaccine ‘home’ and are looking to recruit healthy volunteers to help in this crucial stage of development of what we hope will become a universal coronavirus vaccine.

“Our vaccine is innovative, both in terms of how it aims to protect against the SARS-CoV-2 virus responsible for our current pandemic and future coronaviruses, but also in how it is delivered. If you’re someone who hates needles, our vaccine could be the answer as it’s delivered by a jet of air, not a needle.”

If the clinical trials are successful, the vaccine could be scaled up and manufactured as a powder to boost global vaccination efforts, particularly in low- and middle-income countries.

The clinical trials team at Cambridge University Hospitals NHS Foundation Trust is looking for healthy volunteers aged 18-50 to take part in the study. Volunteers will receive payment for their time, and participation on the trial will last around 12 months with volunteers attending 11 visits. To find out more contact the Project Management Team at

Cambridge researchers honoured at Microbiology Society Annual Awards

Congratulations to Professors Sharon Peacock and Ravindra Gupta who received top awards at the Microbiology Society Annual Awards.

The Microbiology Society awards recognise excellence and are made to those making significant contributions in the field of microbiology, based on nominations received from its membership.

Winners are selected for their work to advance understanding of microbiology and champion the contribution made by microbiology and their work in addressing global challenges. 

Professor Sharon Peacock – Marjory Stephenson Prize 2023

Professor Sharon Peacock

Professor Sharon Peacock, Professor of Public Health and Microbiology at the University of Cambridge and researcher at NIHR Cambridge BRC, is an academic clinical microbiologist who has built her scientific expertise around pathogen genomics, antimicrobial resistance and a range of tropical diseases.

She was the founding director of COG-UK (the COVID-19 Genomics UK Consortium), formed in April 2020 to provide SARS-CoV-2 genomes to UK public health agencies, the National Health Service and researchers. Generating information on variants proved vital for their detection and tracking, and for studies of viral transmissibility, immune evasion, and disease severity.  

Professor Peacock has dedicated more than a decade of her career to the translation of pathogen sequencing into clinical and public health microbiology. She has also used sequencing to examine the extent to which antibiotic-resistant organisms can spread between humans, livestock and the environment. Over her career, Professor Peacock has raised more than £60M in science funding, published more than 500 peer-reviewed papers, and trained a generation of scientists in the UK and elsewhere.

She said of the award: “I am honoured to be the 2023 recipient of the Microbiology Society’s Marjory Stephenson Prize. The prize reflects the work of a large number of dedicated people in the COVID-19 Genomics UK Consortium and beyond, who worked voluntarily and tirelessly across the UK to generate SARS-CoV-2 genomes for public health agencies and researchers worldwide during the pandemic. 

“Microbiology has always been a vitally important discipline, but perhaps never more so than in this era of pandemics, antimicrobial resistance and the exploration of our microbiome and how this influences health and disease. I consider the scientific community fortunate in having the benefit of the ongoing contributions made by the Microbiology Society.” 

Professor Ravindra Gupta – Translational Microbiology Prize 2023


Professor Ravindra Gupta, Infectious Disease Threats theme lead at NIHR Cambridge BRC, has been a Professor of Clinical Microbiology at the Cambridge Institute for Therapeutic Immunology and Infectious Diseases since 2019.  

The Gupta lab based there has worked extensively in HIV drug resistance, both at molecular and population levels, and contributed to the appreciation of the scale of drug resistance globally. The group’s work extends to studies on HIV reservoirs in cells, particularly macrophages.

In 2020 Professor Gupta’s team validated and introduced the SAMBA II point of care test into clinical practice at Addenbrooke’s for rapid diagnosis of COVID-19. During the latter half of 2020 the lab started to study the evolution of the virus within patients in response to antibody-based therapies, as a paradigm of how new variants with multiple mutations have arisen.

The team is also characterising the virology of key spike protein mutations in new variants and their impact on natural and vaccine induced immunity. Professor Gupta is a co-opted member of the New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG). NERVTAG advises the government on the threat posed by new and emerging respiratory viruses. 

In 2020 Professor Gupta was named as one of the 100 Most influential people by TIME. In 2021 he was elected to Fellowship of the Academy of Medical Sciences and in November 2022 featured in the Clarivate list of the world’s most highly cited scientists. 

He said of the award:  “I am thrilled and honoured to receive the Translational Microbiology Prize from the Microbiology Society. For me, it represents a recognition of the work of my team and our collaborators over the years in applying scientific knowledge to combat viruses such as HIV-1 and SARS-CoV-2. This award from an internationally reputed organisation in infectious diseases also provides impetus to continue our endeavours with ever greater passion and commitment.” 

A big congratulations also to Dr Tanmay Bharat, Programme Leader at the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) in Cambridge, who received the Fleming Prize 2023.

Underactive immune response may explain obesity link to COVID-19 severity

Individuals who are obese may be more susceptible to severe COVID-19 because of a poorer inflammatory immune response, say Cambridge scientists.

Scientists at the Cambridge Institute of Therapeutic Immunology and Infectious Disease (CITIID) and Wellcome Sanger Institute showed that following SARS-CoV-2 infection, cells in the lining of the lungs, nasal cells, and immune cells in the blood show a blunted inflammatory response in obese patients, producing suboptimal levels of molecules needed to fight the infection.

Since the start of the pandemic, there have been almost 760 million confirmed cases of SARS-CoV-2 infection, with almost 6.9 million deaths. While some people have very mild – or even no – symptoms, others have much more severe symptoms, including acute respiratory distress syndrome requiring ventilator support.

One of the major risk factors for severe COVID-19 is obesity, which is defined as a body mass index (BMI) of over 30. More than 40% of US adults and 28% of adults in England are classed as obese.

While this link has been shown in numerous epidemiological studies, until now, it has not been clear why obesity should increase an individual’s risk of severe COVID-19. One possible explanation was thought to be that obesity is linked to inflammation: studies have shown that people who are obese already have higher levels of key molecules associated with inflammation in their blood. Could an overactive inflammatory response explain the connection?

Professor Menna Clatworthy

Professor Menna Clatworthy, pictured right, is the Immunity, Inflammation and Transplantation theme lead at NIHR Cambridge BRC and a clinician scientist at the University of Cambridge, studying tissue immune cells at CITIID alongside caring for patients at Addenbrooke’s Hospital, part of Cambridge University Hospitals NHS Foundation Trust. She said: “During the pandemic, the majority of younger patients I saw on the COVID wards were obese. Given what we know about obesity, if you’d asked me why this was the case, I would have said that it was most likely due to excessive inflammation. What we found was the absolute opposite.”

The team analysed blood and lung samples taken from 13 obese patients with severe COVID-19 requiring mechanical ventilation and intensive care treatment, and 20 controls (non-obese COVID-19 patients and ventilated non-COVID-19 patients). These included patients admitted to the Intensive Care Unit at Addenbrooke’s Hospital.

Her team used a technique known as transcriptomics, which looks at RNA molecules produced by our DNA, to study activity of cells in these key tissues. Their results are published in the American Journal of Respiratory and Critical Care Medicine.

Contrary to expectations, the researchers found that the obese patients had underactive immune and inflammatory responses in their lungs.  In particular, when compared to non-obese patients, cells in the lining of their lungs and some of their immune cells had lower levels of activity among genes responsible for the production of two molecules known as interferons (INF) – interferon-alpha and interferon-gamma – which help control the response of the immune system, and of tumour necrosis factor (TNF), which causes inflammation.

When they looked at immune cells in the blood of 42 adults from an independent cohort, they found a similar, but less marked, reduction in the activity of interferon-producing genes as well as lower levels of IFN-alpha in the blood.

Professor Clatworthy said: “This was really surprising and unexpected. Across every cell type we looked at, we found that that the genes responsible for the classical antiviral response were less active. They were completely muted.”

The team was able to replicate its findings in nasal immune cells taken from obese children with COVID-19, where they again found lower levels of activity among the genes that produce IFN-alpha and IFN-gamma. This is important because the nose is one of the entry points for the virus – a robust immune response there could prevent the infection spreading further into the body, while a poorer response would be less effective.

One possible explanation for the finding involves leptin, a hormone produced in fat cells that controls appetite. Leptin also plays a role in the immune response: in individuals who are normal weight, levels of the hormone increase in response to infection and it directly stimulates immune cells. But obese people already have chronically higher levels of leptin, and Clatworthy says it is possible that they no longer produce sufficient additional leptin in response to infection, or are insensitive to it, leading to inadequate stimulation of their immune cells.

The findings could have important implications both for the treatment of COVID-19 and in the design of clinical trials to test new treatments.

Because an overactive immune and inflammatory response can be associated with severe COVID-19 in some patients, doctors have turned to anti-inflammatory drugs to dampen this response. But anti-inflammatory drugs may not be appropriate for obese patients.

Co-author Dr Andrew Conway Morris from the Department of Medicine at the University of Cambridge and Honorary Consultant on the intensive care unit at Addenbrooke’s Hospital said: “What we’ve shown is that not all patients are the same, so we might need to tailor treatments. Obese subjects might need less anti-inflammatory treatments and potentially more help for their immune system.”

Clinical trials for potential new treatments would need to involve stratifying patients rather than including both severe and normal weight patients, whose immune responses differ.

The research was largely supported by Wellcome, the Medical Research Council and the National Institute for Health and Care Research (NIHR), including via the NIHR Cambridge Biomedical Research Centre.

Can health data really save lives?

Health data has the potential to drive research that can improve the treatment and diagnosis of illness – but that data ultimately comes from patients, who may have questions and concerns about its use.

So how can researchers work with patients and the public to co-create boundaries and priorities that allow the use of patient data to save and improve lives in a socially acceptable way?

Join NIHR Cambridge BRC Director Prof Miles Parkes, academic consultant neuro-oncologist Dr Raj Jena and Prof Barbara Pierscionek, Deputy Dean (Research & Innovation) at Anglia Ruskin University, as they look at the benefits of using health data for research – and its possible risks.

Joining them for the panel discussion are lay members Caroline Brocklehurst and Helen Street. Caroline is part of the co-creation group providing the patient perspective for the NIHR Cambridge BRC-funded CYNAPSE​ project, which aims to build a secure infrastructure allowing Cambridge-based researchers to accountably and efficiently use health data to support critical studies. Helen has a background in health data governance and an ongoing interest in patient and public engagement with health data research.
