Recruiting studies
- NCT07215325RecruitingPhase 4

Atlanta, GeorgiaAges 18 years+ - NCT06996938Recruiting
Sexual health screening for women in vulnerable situations
This study offers sexual health checkups and prevention services to women who are in difficult social or financial situations, including those without stable housing or who have sold sex for money. The goal is to see if these services are helpful and acceptable.
ParisAges 18 years+ - NCT06919614RecruitingPhase 3
Testing STIs to Improve PrEP Use in Pregnancy
This trial tests whether STI testing during pregnancy helps more women start and stay on PrEP (a daily pill that prevents HIV). If you join, you'll help find better ways to protect both mother and baby from HIV.
GaboroneAges Any age - NCT04984772Enrolling by invitation
HIV and hepatitis B coinfection follow-up study in Europe
This study follows people who have both HIV and hepatitis B over time to better understand how the infection responds after starting treatment. Your information (and sometimes stored blood samples) helps researchers track changes from the start of therapy to about 2 years later.
Ages 16 years+ - NCT07358910Recruiting
Tracking infectious diseases in communities
This study looks at how infections spread in villages in Cambodia. If you live in a participating village, you might help us understand and prevent disease outbreaks.
Phnom Penh, Phnom PenhAges 2–75 - NCT06638320Recruiting
Hepatitis Delta Risk Study in Hepatitis B Patients
This study looks for hepatitis delta virus (a virus that only affects people with hepatitis B) in patients who have chronic hepatitis B. Researchers want to understand how common this co-infection is and which patients are at highest risk.
Hà Nội, Northern VietnamAges 16 years+ - NCT07610772RecruitingPhase 1
Safety study of a new hepatitis B antibody for hepatitis D
This early-stage trial tests whether a new monoclonal antibody (a lab-made protein that fights viruses) is safe and effective in people with chronic hepatitis D infection. Hepatitis D only occurs in people who also have hepatitis B, and this new treatment may help control the virus.
AarhusAges 18–70 - NCT07476339RecruitingPhase 4
Returning to HIV Care with Biktarvy
This trial tests the medication Biktarvy (bictegravir, emtricitabine, and tenofovir alafenamide) for people with HIV who have stopped taking their antiretroviral therapy (ART) for at least 12 weeks and are ready to restart treatment. It aims to see how well the medication works when restarting care.
Clearwater, FloridaAges 18 years+ - NCT05668026RecruitingPhase 1/Phase 2
Venetoclax to shrink HIV reservoir in people on stable ART
This Phase 1/2 study tests whether venetoclax can help reduce the “HIV reservoir,” which is a hidden group of HIV-infected cells, while you stay on your usual HIV treatment. It also looks at whether the drug helps these infected cells die off in a controlled, safe way.
Melbourne, MelbourneAges 18–65 - NCT06484335RecruitingPhase 1
HIV vaccine study with treatment pause for Thai adults
This study tests whether adding an experimental vaccine can help your immune system control HIV during a temporary break from your antiretroviral therapy (ART). If you have been on ART since shortly after infection with a suppressed viral load, this trial could help you understand if a 'functional cure' is possible.
Pathum Wan, BangkokAges 18–60 - NCT05147519Recruiting
Observes HIV and other infections to learn who gets them
This is an observational study that follows people to better understand how HIV and other infections (like sexually transmitted infections) happen and change over time. It may help researchers improve prevention and care, but it is mainly for monitoring rather than testing a new treatment.
Kericho, Kericho CountyAges 14–55 - NCT07875218Enrolling by invitation
Hepatitis B care within Zambia's HIV programme
This study looks at how to bring hepatitis B testing and care into the same clinics that already provide HIV services in Zambia. It aims to make it easier for people to get the hepatitis B help they need.
Lusaka, Lusaka ProvinceAges 18 years+ - NCT07519330RecruitingPhase 2
Testing HH-006 treatment for chronic hepatitis B
This study tests a new drug called HH-006 to see if it can help treat chronic hepatitis B infection. Participants will be grouped by their infection level, and the study checks whether the drug is safe and works to reduce the hepatitis B virus.
Chongqing, Chongqing MunicipalityAges 18–45 - NCT07487623Recruiting
Nutritional supplement for liver protection in hepatitis C
This trial tests whether a special nutritional supplement can protect the liver in people with chronic hepatitis C. If you have mild to moderate liver damage and meet the criteria, you may be able to join.
Guadalajara, JaliscoAges 18–69 - NCT07317687Recruiting
Rapid HIV, Hep C, and Syphilis Testing in Street Medicine
This trial offers free rapid testing for HIV, hepatitis C, and syphilis during street medicine visits. It helps find infections early so you can get connected to care.
Harpers Ferry, West VirginiaAges 18 years+ - NCT07240350Recruiting
Hepatitis B immune response in surgery patients
This study looks at how the body's immune system responds in people with chronic hepatitis B who also need surgery on certain organs. The goal is to learn more about the immune reaction in tonsils, lymph nodes, or other tissues to help find better treatments for hepatitis B.
Guangzhou, GuangdongAges 18–75 - NCT07200908RecruitingPhase 3
Comparing brelovitug and bulevirtide for hepatitis delta
This trial tests a new drug, brelovitug, against an existing one, bulevirtide, for people with chronic hepatitis delta. It aims to find a better treatment to lower the virus and protect the liver.
GrazAges 18–99 - NCT06650852RecruitingPhase 2
A study of 3 drugs for chronic hepatitis B
This trial tests a combination of three drugs (BRII-179, BRII-835, and PEG-IFNα) to see if they can better control chronic hepatitis B. It is for people who are already on antiviral therapy and have well-controlled virus levels.
Beijing, Beijing MunicipalityAges 18–60 - NCT07024641RecruitingPhase 1
Safety study of GIGA-2339 for chronic Hepatitis B
This study tests an experimental antibody (GIGA-2339) given as an infusion to people with chronic Hepatitis B. It aims to see if the drug is safe and how the body processes it, possibly helping to control the virus.
Chandler, ArizonaAges 18 years+ - NCT05652088Recruiting
Study gut immune tissue in HIV cure efforts
This study looks at how immune tissue in the gut may be involved in curing HIV. You may be asked to have two colonoscopies while on an HIV “cure-related” treatment, so researchers can collect tissue samples to understand what’s happening in your body.
New York, New YorkAges 18–75 - NCT06395129Recruiting
Better syringes for people who inject drugs
This study provides safer, low-dead-space syringes to people who inject drugs to help reduce the spread of infections like HIV and hepatitis C. It is designed for people in low- and middle-income countries who use needle exchange programs.
YerevanAges 18 years+ - NCT05590455RecruitingPhase 2
Testing a TNF-blocking drug to reduce death in HIV and TB meningitis
This Phase 2 trial studies whether a TNF-blocking medicine can lower the risk of death in people with HIV who also have TB meningitis. You would receive standard TB meningitis treatment plus the study drug, if you meet the criteria.
Rio de JaneiroAges 18 years+ - NCT05051098Recruiting
Registry for people with hepatitis B infection
This study is a registry, meaning it collects health information from people living with hepatitis B rather than giving a new treatment. It may help researchers better understand different hepatitis B groups and outcomes over time.
HanoverAges 18 years+ - NCT04375800RecruitingPhase 2
Doravirine for children with HIV infection and stable treatment
This Phase 2 study tests doravirine (a type of HIV medicine) in children with HIV who are about 4 weeks to under 12 years old and weigh under 45 kg. It aims to see whether this regimen can control the virus safely, and some children may continue into an extension if they benefit.

- Does it cost anything to join a sexually transmitted infections (not hiv or hepatitis) trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
