Recruiting studies
- NCT04014413Recruiting
Fecal transplant for gut and immune-related conditions
This trial studies whether fecal microbiota transplantation (FMT)—a medical procedure using stool from a screened donor to restore gut bacteria—can improve safety and outcomes for people with certain bowel, immune, and metabolic conditions. It may help if your symptoms are thought to be related to an unhealthy gut microbiome, though eligibility is broad and depends on specific safety factors.
Hong Kong, ShatinAges Any age - NCT06966908Recruiting
Managing hepatitis B in non-specialty hospital settings
This study looks at how patients with chronic hepatitis B are managed when they visit non-liver clinics. It aims to improve care and may also include a survey about quality of life for those starting treatment.
Guangzhou, GuangdongAges Any age - NCT06805656RecruitingPhase 2
Trial to reduce HIV reservoirs aiming for treatment-free remission
This study tests whether a combination approach, including a drug called nicotinamide (a form of vitamin B3) and other strategies, can reduce the hidden HIV reservoir enough to allow a temporary pause in antiretroviral therapy without the virus rebounding. It is for people who have well-controlled HIV and strong immune systems.
São Paulo, São PauloAges 18–65 - NCT04851015RecruitingPhase 3
Low-dose TMP-SMX for Pneumocystis pneumonia (PCP)
This Phase 3 study tests whether low-dose trimethoprim-sulfamethoxazole (also called TMP-SMX) can treat Pneumocystis pneumonia (PCP) in people with weakened immune systems. It may help improve treatment while reducing side effects compared with standard dosing.
Montreal, QuebecAges 18–100 - NCT06023056Recruiting
Hepatitis B vaccine after newborn surgery
This trial tests whether giving the hepatitis B vaccine to full-term newborns who had multiple stomach or intestine surgeries is safe and works well. It aims to protect these babies from hepatitis B infection.
Chongqing, Chongqing MunicipalityAges Any age - NCT06126913Recruiting
Community HIV care for people newly diagnosed
This study tests whether getting HIV care through a community program is as helpful as going to a clinic for people who just found out they have HIV. It looks at how well they stay in care and take their medicine.
KampalaAges Any age - NCT07481175RecruitingPhase 1
Testing a drug to reduce hidden HIV early after treatment start
This trial tests whether adding venetoclax, a drug that helps infected cells die, at the start of HIV treatment can lower the amount of hidden virus that stays in the body. It may help reduce the HIV reservoir.
AarhusAges 18–70 - NCT04166266Recruiting
Study of adults with hepatitis D and hepatitis B coinfection
This study follows adults who have ongoing hepatitis D infection along with hepatitis B. It aims to better understand this mixed infection and how these patients do over time.
AngersAges 18 years+ - NCT04970836Recruiting
Hepatitis B revaccination for young adults in Taiwan
This study looks at how well your immune system responds after getting 1–2 extra doses of the hepatitis B vaccine. It may help doctors understand who needs revaccination and how to strengthen protection.
TaipeiAges 20–36 - NCT07079150Recruiting
Long-term pegylated interferon study for HBV families with poor outcomes
This study looks at how well pegylated interferon alpha-2b works over the long term for people with chronic hepatitis B who come from families where the virus has caused serious liver problems like cirrhosis or liver cancer. The goal is to see if this treatment can help prevent these bad outcomes in family members.
Xi'an, ShaanxiAges 18–70 - NCT06431945Recruiting
Hepatitis C testing for injection drug users
This trial offers free hepatitis C testing for people who inject or have injected drugs. The goal is to find hidden cases early so they can get treatment.
BrnoAges 18 years+ - NCT05973825Recruiting
HIV blood study to study immune responses over many years
This study looks at how the immune system and HIV behave in people on long-term HIV treatment (ART), using blood samples that will be stored for future tests for up to 20 years. It may help researchers understand how well treatment is controlling HIV and improve future care.
Ghent, Oost-VlaanderenAges 18–80 - NCT03449706Recruiting
Tracking immune changes in early HIV
This study looks closely at how your immune system and HIV infection markers change right after a new HIV diagnosis. It may help doctors understand the earliest stages of HIV and improve how infections are measured and followed over time.
Ghent, Oost-VlaanderenAges 18–65 - NCT03135886Recruiting
Testing for HIV in opioid treatment programs
This project studies how to improve offering and completing HIV (and hepatitis C) tests in opioid treatment programs. It may help increase timely follow-up and linkage to care when results are positive.
New York, New YorkAges 18 years+ - NCT00001281Recruiting
Understanding how HIV affects blood cells and body fluids
This research study examines how HIV works in the blood and body fluids of people with and without HIV. By studying blood samples, researchers hope to better understand HIV infection and develop better treatments.
Washington D.C., District of ColumbiaAges 18–120 - NCT05392387Recruiting
Treatment and outcomes study for long-term hepatitis B
This trial looks at people with long-term hepatitis B infection and studies how treatment may affect health over time. It may help you understand whether your care improves outcomes for chronic hepatitis B.
Changsha, HunanAges 18–79 - NCT05988879Recruiting
Functional cure for hepatitis B in HIV/HBV co-infection
This trial tests whether people with both HIV and hepatitis B can achieve a functional cure for hepatitis B. It aims to see if current treatment can be stopped safely after the hepatitis B virus is no longer active.
Guangzhou, GuangdongAges 18–65 - NCT04653610Recruiting
Study immune signals in untreated HIV using extra samples
This study looks at tiny cell “messengers” in blood and stool to understand how HIV behaves before and after starting treatment. You may be eligible if you have untreated HIV (or you’re a healthy volunteer) and can commit to many sample visits, including long-term storage for 20 years.
Ghent, Oost-VlaanderenAges 18–65 - NCT07852091RecruitingPhase 2
Combination therapy aiming for a functional cure for chronic hepatitis B
This study tests a new combination of medicines to help your immune system control the hepatitis B virus, with the goal of stopping the need for long-term treatment. It may be an option for people who have taken or are currently taking hepatitis B medications.
Chongqing, Chongqing MunicipalityAges 18–60 - NCT07845058RecruitingPhase 2
Combination therapy for a functional cure of chronic hepatitis B
This trial tests a new combination of medicines to help your body control the hepatitis B virus without needing lifelong treatment. It aims for a 'functional cure,' which means the virus stays inactive and your liver stays healthy.
Chongqing, Chongqing MunicipalityAges 18–60 - NCT07719491RecruitingPhase 1
Study of GS-0415 in People with HIV
This study tests a new drug, GS-0415, for people with HIV. The study will see if this drug can help control the virus. Participants will continue taking their regular HIV medication.

Colchicine to lower heart artery swelling in HIV
This trial tests if colchicine, a medicine for inflammation, can reduce swelling in the heart arteries of people with HIV. It may help lower the risk of heart problems in those already on a statin or similar medication.
BarcelonaAges 50 years+ - NCT03684655RecruitingPhase 2
PET-MR scan study of immune activity in people with HIV
This Phase 2 study uses a special whole-body scan (PET-MR) to measure immune activity in people living with HIV. It may help researchers understand how well the immune system responds and how to better track HIV-related inflammation.

Study of new HIV injection vs. standard injectables
This phase 3 trial tests a new long-acting, injectable two-drug combination (lenacapavir + teropavimab + zinlirvimab) vs. another injectable combo (cabotegravir + rilpivirine) for people whose HIV is already well-controlled on daily oral meds. It aims to see if the new combo can keep the virus under control with fewer injections.
