Bioequivalence clinical trial of two formulations of linagliptin/metformin
This study is comparing two different forms of a medicine that has two active ingredients: linagliptin and metformin. These ingredients are commonly used together to help manage type 2 diabetes. The main goal is to see if a new version of this combined medicine works in exactly the same way as an existing one in the body. They’re doing this by giving the medicines to healthy volunteers and measuring how much of each ingredient gets into the bloodstream. This type of study, called a bioequivalence study, helps ensure that any new or generic version of a medicine is just as effective and safe as the original one, even if it looks a little different. It's a very early stage of research to make sure new medicines are reliable.
At a glance
What is this study about?
Imagine you have a favourite brand of crisps, but then a new brand comes out that says it's exactly the same. This study is a bit like that, but for an important medicine used to treat type 2 diabetes. This medicine contains two active ingredients, linagliptin and metformin, which work together to help control blood sugar levels.
The main purpose of this study is to compare two different versions of this combined medicine. Researchers want to make sure that a new version (which might be made by a different company or in a slightly different way) behaves exactly the same in healthy people's bodies as an already approved version. This means checking if the new version delivers the same amount of the active ingredients into the bloodstream at the same speed and for the same length of time.
This kind of research, called a 'bioequivalence study', is really important. It helps regulatory bodies, like the UK's Medicines and Healthcare products Regulatory Agency (MHRA), ensure that when a new version of a medicine becomes available, it will work just as well and be just as safe as the original. It reassures doctors and patients that they can expect the same good results, no matter which version of the medicine they are using. It’s a foundational step to bringing reliable medicines to market.
Key takeaways
- Compares two versions of a diabetes medicine (linagliptin/metformin).
- Aims to ensure a new version works just like an original one.
- Specifically for healthy adults (18+).
- Involves taking the medicine and having regular blood tests.
- Helps make sure new medicines are reliable and safe.
- Participation involves clinic visits, potentially with overnight stays.
Who may be eligible?
This study is looking for healthy adults to take part. To be considered, you need to be at least 18 years old, and there is no upper age limit, meaning older adults are welcome to participate too. The study is open to both men and women.
Since this is an early-stage study designed to see how the medicine works in a typical body, it's very important that participants are generally in good health. This means you shouldn't have any major ongoing medical conditions that could affect how your body responds to the medicine or make taking part unsafe.
Specific details about other things that might make you unsuitable, such as certain medications you might be taking, or other health background, would be discussed by the study team. They will carry out thorough health checks to make sure joining the study is safe for you.
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 18 years old or older?
- Are you generally in good health?
- Are you comfortable with regular blood samples?
- Are you able to commit to several clinic visits, possibly including overnight stays?
- Are you not currently taking any medications that might conflict with the study (this would be checked by the team)?
What does participation involve?
If you decide to take part, you would receive one of two different versions of the linagliptin/metformin medicine. You wouldn't be told which version you're getting at the time, which helps make the results fairer. You'd likely visit a study clinic multiple times over a period. During these visits, the study team would take blood samples regularly to measure how your body is processing the medicine. They might also monitor your blood pressure and heart rate, and ask about your general well-being.
There might be some overnight stays required at the clinic, especially right after you take the medication, so that detailed measurements can be taken frequently. You would be given instructions on what you can and cannot eat or drink before and during these visits. The total duration of the study, from your first visit to your final check-up, is usually a few weeks to a couple of months, depending on how many different study periods there are and how long each takes.

Common questions
What is 'bioequivalence'?
It means checking if two different versions of the same medicine work in exactly the same way in the body.
Why is this study for healthy volunteers?
Researchers want to see how the medicine works in a healthy body first, without other health conditions making it complicated.
Will I know which medicine I'm getting?
No, usually in these studies, neither you nor the study team knows which version you receive to ensure fair results.
Will I get paid for taking part?
Many clinical trials offer payment for your time and travel, but this would be confirmed by the study team.
What's the medicine used for normally?
Linagliptin and metformin are active ingredients combined in a medicine to help people with type 2 diabetes manage their blood sugar.
