Tenofovir alafenamide versus entecavir for chronic hepatitis B
This study compares two approved hepatitis B medicines—tenofovir alafenamide and entecavir—to see which works best for people with chronic hepatitis B. It may help improve control of the virus and support better long-term liver health.
Taichung, TaichungAges 20 years+ - NCT03936998RecruitingPhase 1/Phase 2
Study drug for peanut allergy to change immune response
This early-phase study tests VE416, a treatment meant to help reduce peanut allergy reactions by changing how the immune system responds. If you have documented peanut allergy, you may receive the study medicine and, for some people, take part in a supervised peanut “entry challenge.”
Boston, MassachusettsAges 12–55 - NCT03938155Recruiting
Risk check program for older women in Manitoba
This trial looks at how well a health risk assessment can identify heart and blood-vessel problems in women 55 and older. It may help doctors target prevention earlier, which could lower the chance of serious events.
Winnipeg, ManitobaAges 55 years+ - NCT03949855RecruitingPhase 2
Belimumab plus rituximab for primary membranous nephropathy
This study tests whether adding belimumab to rituximab helps people with primary membranous nephropathy (a kidney disease) that has the right blood test marker and specific protein levels. The goal is to improve kidney outcomes and reduce disease activity while keeping treatment safe.
Birmingham, AlabamaAges 18–75 - NCT03946930Recruiting
Study of memory decline in Alzheimer’s disease
This trial studies people diagnosed with Alzheimer’s disease who are at a moderate stage of decline. It likely involves cognitive (memory/thinking) testing and care-partner input to help track changes over time.
Hong KongAges 65–92 - NCT03951311Recruiting
Diet and lifestyle study for people with weaker heart pumping
This study looks at how metabolic changes, diet, and lifestyle patterns affect heart failure. It may help find ways to improve symptoms and health by targeting diet and daily habits.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 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.
