New Haven, ConnecticutAges 18–65 - NCT04368039Recruiting
Breathing regular air pressure oxygen for first-time psychosis
This trial tests whether breathing oxygen (not high-pressure) can improve symptoms in people experiencing a first episode of psychosis. It may help reduce symptoms by changing oxygen delivery to the brain early in the illness.
Columbus, OhioAges 15–35 - NCT04372615RecruitingPhase 2
Inebilizumab for NMDA receptor encephalitis after initial steroids
This Phase 2 study tests inebilizumab in people with NMDA receptor encephalitis, an immune-related brain condition. It looks to see if adding this treatment after starting steroids (and possibly other first treatments) improves recovery and safety.
Birmingham, AlabamaAges 12 years+ - NCT04374799RecruitingPhase 3
Heparin vs placebo during cardiac catheterization
This trial tests whether giving heparin (a blood thinner) during a specific type of heart procedure is safer and works better than not giving it. It focuses on patients where the blood supply in the hand’s artery connection is functioning properly.
Hamilton, OntarioAges 18 years+ - NCT04380740RecruitingPhase 2
Longer vs shorter abatacept doses to prevent graft-versus-host disease
This trial tests whether giving abatacept for a longer or shorter time can better prevent graft-versus-host disease (a common complication after a stem cell transplant). If you’re having a planned unrelated donor transplant, the results may help reduce the risk or severity of transplant-related immune problems.

Common questions
- Are there clinical trials for placebo - control?
- Yes. Clin2 currently lists 3,962 recruiting placebo - control 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 placebo - control 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 placebo - control 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.
