Boston, MassachusettsAges 35–74 - NCT05139706Recruiting
Study immune side effects after cancer immunotherapy
This study looks at how immune-related side effects happen in people treated with certain cancer immunotherapies. It also includes some healthy volunteers and people who already have similar autoimmune conditions, to better understand and compare these reactions.
Montreal, QuebecAges 18–100 - NCT05257629RecruitingPhase 3
Aggressive smoking quit program after heart problems
This trial tests whether a strong quit plan using varenicline (a quit pill) plus nicotine e-cigarettes, along with counseling, helps people stop smoking after a recent heart-related event. It’s aimed at people who want to quit and can safely stay involved for about a year.
New Westminster, British ColumbiaAges 18 years+ - NCT05336695RecruitingPhase 1/Phase 2
Brain scan study to measure fibrin in Alzheimer’s
This early study (Phase 1/2) uses brain imaging to look for “fibrin” (a blood-clot–related protein) in people with Alzheimer’s disease and related conditions. The goal is to understand whether fibrin changes can be seen on scans and what it might mean for Alzheimer’s.
Boston, MassachusettsAges 55–90 - NCT05368987Recruiting
TMS for PTSD fear learning and safety memory
This study tests a brain-stimulation treatment called TMS to see if it improves how people with PTSD unlearn fear and form safer memories. It may help reduce fear responses by targeting specific fear-circuit areas in the brain.
Houston, TexasAges 18–70 - NCT05436418RecruitingPhase 1/Phase 2
Lower-dose transplant medicines to prevent graft-versus-host disease
This early-phase study tests a lower dose of cyclophosphamide given after a stem cell transplant to prevent graft-versus-host disease (GVHD). It also uses sirolimus and mycophenolate to improve how well the donor immune system accepts the transplant, aiming to reduce side effects while keeping protection against GVHD.
Duarte, CaliforniaAges 12–120 - NCT05443100Recruiting
Testing whole-body cold therapy for metabolic, neurologic, or fibromyalgia pain
This trial studies whether a whole-body cold therapy called “WBC” can help people with certain metabolic conditions, neurologic conditions, or fibromyalgia. You may be able to join if you meet age and weight requirements and don’t have certain medical or safety risks.
Oggebbio, Verbano-Cusio-OssolaAges 18–65 - NCT05519475RecruitingPhase 2
Gene-silencing medicine trial for adults with MASH and liver scarring
This Phase 2 study tests a gene-silencing treatment to improve chronic liver disease called MASH, especially in people with certain genetic risk. You may be eligible if you have MASH with moderate-to-advanced scarring and specific test results, and if other liver causes and recent substance/alcohol issues don’t apply.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,789 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.
