A Trial Within Cohort Feasibility Study Design Comparing Standard of Care Versus Weight Loss (Achieved Through Tirzepatide) for Obesity-related Hypertension in Young Adults
This study aims to understand how a new weight loss medication, Tirzepatide, impacts high blood pressure in young adults who are overweight or obese. High blood pressure and obesity are very common, and often linked, especially in younger people. While lifestyle changes are often recommended, they don't always lead to long-term weight loss or significant blood pressure drops. Newer weight loss drugs like Tirzepatide have shown strong results in helping people lose weight, which in turn can lower blood pressure. This study will compare the effects of this intensive weight loss with standard treatments, looking at how much and how quickly blood pressure improves. It's a small, early-stage study to see if this approach could be a game-changer for managing high blood pressure in this group.
At a glance
What is this study about?
High blood pressure (hypertension) is a very common health issue, affecting many adults in the UK, and it's a major cause of serious health problems worldwide. Being overweight or obese is also very common in the UK, and these two conditions often go hand-in-hand. In fact, a significant number of high blood pressure cases, especially in younger adults, are linked to being overweight or obese. When you're younger, there's an even stronger connection between your weight and your blood pressure.
Doctors usually recommend lifestyle changes, like healthy eating and exercise, to help people lose weight and lower their blood pressure. However, it can be really hard to achieve and maintain significant weight loss this way, and the blood pressure benefits might not be as big as hoped. Recently, new medications originally for type 2 diabetes, like Tirzepatide, have shown great promise in helping people lose a lot of weight. This weight loss seems to also have a good impact on blood pressure, potentially more so than traditional lifestyle changes.
This study is an early-stage exploration (a 'feasibility study') to see if using a powerful weight loss medication like Tirzepatide can significantly lower blood pressure in young adults who have both high blood pressure and are overweight or obese. We want to compare this new approach to the standard care, which usually involves blood pressure medicines and lifestyle advice. The aim is to understand how much blood pressure can be reduced and how quickly, to see if intensive weight loss could be a better way to manage or even solve high blood pressure for some young people.
Key takeaways
- Targets young adults (18-40) with high blood pressure and overweight/obesity.
- Compares a new weight loss medicine (Tirzepatide) to standard blood pressure care.
- Aims to see if losing weight can significantly lower blood pressure.
- Could help reduce or remove the need for lifelong blood pressure medication.
- This is a feasibility study, meaning it's an early look into this approach.
- Taking place at Addenbrooke's Hospital in Cambridge.
Who may be eligible?
This study is looking for young adults between 18 and 40 years old who are overweight or have obesity (meaning their Body Mass Index, or BMI, is 27 or higher). You also need to have been diagnosed with high blood pressure but not severely high, with specific readings (your top number, or systolic, should be between 135 and 159, and/or your bottom number, or diastolic, should be between 85 and 99). You can be taking up to one blood pressure medication to qualify.
However, there are reasons why you might not be able to join. For instance, if your doctor thinks you have a different type of high blood pressure (not 'primary' hypertension), or if you have certain existing health conditions like known heart failure, kidney problems, specific thyroid cancers, or a history of pancreatitis. You also can't participate if you have diabetes (type 1 or 2) or if you're already taking similar injectable medications for diabetes or weight loss. If you've had or plan to have weight loss surgery, or if you've recently had a big change in your weight, you wouldn't be able to join either. In general, if there's anything in your medical history that the study doctors think makes it unsafe for you to take part, you won't be able to.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 40 years old?
- Are you overweight or obese (BMI 27 or higher)?
- Have you been diagnosed with high blood pressure but it's not severely high?
- Are you taking no more than one blood pressure medication?
- Do you NOT have diabetes (Type 1 or 2)?
- Have you NOT had weight loss surgery or recently lost a lot of weight unintentionally?
What does participation involve?
If you join this study, you'll be looked after by the clinical pharmacology/hypertension team at Addenbrooke's Hospital in Cambridge. You might receive the weight loss medication Tirzepatide, or you might continue with standard care, which involves existing blood pressure medications and lifestyle advice. The study will carefully track your blood pressure and weight over time. You'll have regular visits to the hospital for check-ups, assessments, and to monitor how you're doing. The team will explain exactly what's involved in terms of appointments, medication schedules, and how long the study will last for you.

Common questions
What is high blood pressure?
High blood pressure means the force of your blood pushing against your artery walls is consistently too high. It can lead to serious health problems over time if not managed.
What is Tirzepatide?
Tirzepatide is a medication that helps with weight loss and can also lower blood sugar levels. It works by affecting natural hormones in your body that control appetite and how your body uses sugar.
Why are young adults being studied?
The link between being overweight/obese and having high blood pressure is especially strong in young adults. The study wants to see if intensive weight loss can have a big impact early on.
Will I have to eat a special diet or exercise?
The study aims to compare intensive weight loss (through medication) with standard care which includes lifestyle advice. Specific diet and exercise guidance will depend on which group you're in, and will be explained by the study team.
Where is this study taking place?
This study is taking place at Addenbrooke's Hospital in Cambridge, specifically within their clinical pharmacology/hypertension service.
