Recruiting studies
- NCT05855083RecruitingPhase 2
Narsoplimab for high-risk TMA after bone marrow transplant

Common questions
- Are there clinical trials for efficacy and safety?
- Yes. Clin2 currently lists 2,830 recruiting efficacy and safety 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 efficacy and safety 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 efficacy and safety 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.
