CAR-T therapy study for rebuilding HIV immune defenses
This early-stage study tests whether CAR-T cells can help rebuild the immune system’s ability to fight HIV. You may be a candidate if your HIV is well controlled on standard treatment and you don’t have certain serious infections or organ problems.
Guangzhou, GuangdongAges 18–60 - NCT05094284Recruiting
Heart stent registry for adults needing coronary stenting
This registry enrolls adults who are about to get a heart stent and have significant blockage in their coronary arteries. It aims to collect real-world information about stenting for different types of heart conditions, which may help improve future care.
Shatin, New TerritoriesAges 18 years+ - NCT05408897Recruiting
Blood test to predict risk after surgery for high-risk GIST
This study uses a “liquid biopsy” blood test to look for leftover cancer signals after surgery. It aims to predict how well treatment will work and how likely the cancer is to come back in people with high-risk GIST.
Beijing, Beijing MunicipalityAges Any age - NCT05546086Recruiting
Beijing health study for adults who live in Beijing
This study collects health information from adults (18+) who are permanent residents of Beijing. It aims to learn patterns about health in the local population and how different factors may affect outcomes over time.
BeijingAges 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+ - NCT02714387Recruiting
Study of serious complications from non-traumatic blood vessel brain problems
This study follows people who have non-injury (non-traumatic) blood-vessel-related problems in the brain to understand serious complications. It may help researchers identify risks and improve care over time.
AngersAges 15 years+ - NCT02850588Recruiting
Track outcomes after carotid stent or surgery
This study follows people who need a procedure to treat narrowed carotid arteries, comparing results after either surgery (CEA) or a less invasive procedure (TCAR). It mainly looks at patient safety and outcomes, which can help improve future care.
Chicago, IllinoisAges 18 years+ - NCT03852407RecruitingPhase 2
Two kinds of conditioning before matched stem cell transplant
This trial compares two reduced-intensity conditioning regimens before you receive stem cells from a donor who matches your HLA type. It aims to find which approach works better and is safer for certain blood cancers.
AntwerpAges 18–75 - NCT05423860Recruiting

Test ixekizumab and stopping it in plaque psoriasis
This study looks at how well ixekizumab (an injection medication) works for moderate-to-severe plaque psoriasis, and what happens when the treatment is withdrawn. It may help you learn whether stopping the medicine is safe and how skin disease outcomes change over time.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 recruiting general population (no specific condition or disease) studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a general population (no specific condition or disease) trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a general population (no specific condition or disease) 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.
