Alcohol and sexual health program for men at risk of HIV
This study tests an alcohol- and sexual-health program to help reduce HIV risk in men who recently had condomless sex and drink heavily. It may help you by offering structured support around drinking and HIV prevention (PrEP).
Gainesville, FloridaAges 18–30 - NCT04342026Recruiting

MontpellierAges 1 month–18 years - NCT04395196RecruitingPhase 2
Prenatal choline for pregnancy after alcohol exposure
This trial tests whether taking a choline supplement during pregnancy can reduce harmful effects on the baby when a person drinks heavily while pregnant. It may help support healthier pregnancy and baby outcomes for those who meet the study’s drinking and nutrition criteria.
Cape Town, Western CapeAges 18–45 - NCT04426461Recruiting
Predicting therapy response for anxiety and depression
This study uses questionnaires (and likely computer tasks) to better predict how you might respond to behavioral therapy for anxiety and depression. If you qualify, your answers help researchers build tools to guide treatment decisions in the future.
Tulsa, OklahomaAges 18–65 - NCT04430257Recruiting
PrEP for people at higher risk of HIV
This study checks whether taking HIV prevention medicine called PrEP can help protect people who are not living with HIV but have recent risk of HIV exposure. You may qualify if you have ongoing risk and are not already taking PrEP.
Cambridge, MassachusettsAges 18 years+ - NCT04527445Recruiting
Test to use less X-ray during sacral nerve lead placement
This trial studies whether doctors can place a sacral neuromodulation lead using fewer X-rays. If you’re getting this procedure for overactive bladder, it may help reduce radiation exposure while still guiding correct lead placement.
Loma Linda, CaliforniaAges 18–89 - NCT04626050Recruiting
PTSD and stress support study for healthcare workers
This study looks at psychological distress, including post-traumatic stress disorder (PTSD), in healthcare workers after work-related trauma. You may be eligible if you are an adult healthcare worker with PTSD (and otherwise stable) who can complete regular study check-ins.
New York, New YorkAges 18 years+ - NCT04823923Recruiting
How kidney failure affects drug levels in metastatic kidney cancer
This study looks at how chronic kidney failure changes the amount of certain cancer medicines in the blood. It involves people with metastatic clear cell kidney cancer who take pazopanib or cabozantinib, and compares drug levels in different kidney function groups.
MarseilleAges 18 years+ - NCT04855773Recruiting
Mobile text-message support to help people stay on PrEP
This trial tests whether phone-based (iPhone/Android) text-message support can improve how consistently people use PrEP, an HIV prevention medicine. It may help you stay on track with refills and clinic visits, especially if you’re at higher risk of stopping PrEP.
San Francisco, CaliforniaAges 15 years+ - NCT04859218Recruiting
Study whether O-type blood affects outcomes in MDS patients
This study looks at whether receiving red blood cell transfusions from O-type donors changes outcomes for people with low-risk myelodysplastic syndrome (MDS). It may help doctors choose which blood types to use to improve how patients feel and function over time.
Hamilton, OntarioAges 18–120 - NCT04887116RecruitingEarly Phase 1
Virtual reality sessions to treat PTSD in healthcare workers
This early-phase study tests whether guided virtual reality experiences can reduce symptoms of PTSD (post-traumatic stress disorder) or near-PTSD in healthcare workers. It may help people who have stress reactions related to work during the COVID-19 era.
