A clinical study of MK-4646 in people with HIV (MK-4646-003)
This clinical trial is testing a new investigational drug called MK-4646 in people living with HIV. It is an early-stage research study, also known as a Phase 1 trial. The main goal is not to cure HIV, but to find out how safe the medicine is, how the human body processes it, and whether it causes any unwanted side effects. Taking part helps scientists understand if MK-4646 could be developed into a helpful treatment in the future. The trial is open to adults aged 18 and over who have HIV. If you join, the study team will closely monitor your health with regular blood tests and check-ups. Taking part is completely voluntary, and you can change your mind and leave the study at any point without affecting your routine NHS care.
At a glance
What is this study about?
HIV is a virus that affects the immune system, making it harder for the body to fight off infections. Thanks to modern antiretroviral treatments, people with HIV can live long, healthy lives, often with the virus suppressed to undetectable levels. However, researchers are constantly searching for new, more convenient, or more effective medicines to offer people living with HIV better long-term options.
This trial is looking at an experimental medicine called MK-4646. Because this is a Phase 1 study, it is one of the first times this drug is being tested in humans. The researchers need to learn the basics: what dose is safe, how quickly the body absorbs and clears the medicine, and whether it causes any unpleasant or harmful side effects.
Understanding how MK-4646 behaves in the body is a vital step before it can be tested in larger groups of people. Although this study will not provide a cure, the knowledge gathered from participants could pave the way for new HIV treatments in the future.
Key takeaways
- This is an early-stage (Phase 1) trial testing an experimental HIV drug called MK-4646.
- The main focus is finding out if the medicine is safe and how the human body handles it.
- The study is open to adults aged 18 and over who are living with HIV.
- Participants will receive close medical monitoring and regular health checks.
- Participation is entirely voluntary, and you can withdraw from the study at any time.
Who may be eligible?
This study is open to men and women aged 18 and over who have been diagnosed with HIV. Because this is an early-stage safety trial, participants usually need to be in generally stable health, apart from their HIV diagnosis.
There are specific medical rules about who can join. For instance, you may need to have your HIV well-controlled on current medication, or meet certain criteria regarding your viral load and immune cell counts. People with certain other active infections, severe liver or kidney problems, or those taking specific medications that interact with the study drug might not be able to take part.
Because detailed medical guidelines apply, the trial team and your regular HIV clinic doctor will review your full medical history and perform baseline health checks to ensure taking part 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.
- I am aged 18 or older.
- I have a confirmed diagnosis of HIV.
- I am in generally stable health.
- I am willing to attend regular clinic visits and have blood tests taken.
- I am happy to discuss my current medications with the research team.
What does participation involve?
If you take part, you will be invited to a specialised trial clinic for several visits. The study starts with a screening visit, where doctors carry out health checks, such as blood tests, urine tests, and an electrocardiogram (ECG) to check your heart, making sure the study is suitable for you.
If you join, you will be given the study drug, MK-4646. You will need to attend regular clinic visits so the team can monitor how your body responds. This involves giving blood samples at set times so scientists can measure how much medicine is in your bloodstream. You will also be asked to track how you feel and report any symptoms. The study team will explain the total duration of the study, how often you need to visit, and whether any overnight stays at the clinic are required.

Common questions
What is a Phase 1 clinical trial?
A Phase 1 trial is an early test of a new medicine in a small group of people. Its primary purpose is to test safety, find the right dose, and see how the body processes the drug.
Will this trial cure my HIV?
No, this study is not designed to cure HIV. It is an early safety study to see how a new medicine behaves in the human body.
Do I have to stop taking my regular HIV medication?
You should never stop taking your prescribed medication without speaking to your doctor. The study team will tell you how the trial medicine fits alongside your current treatment.
Will taking part cost me anything?
Trial medicines and study-related tests are provided free of charge. Most clinical trials also cover reasonable travel expenses so you are not out of pocket.
Can I leave the study if I change my mind?
Yes, taking part is completely voluntary. You are free to stop participating at any time, and doing so will not affect your normal NHS care.
