Fullerton, CaliforniaAges 18 years+ - NCT05264753Recruiting
Follow-up study for a device that closes an abnormal heart blood vessel
This study checks how well and how safely the Occlutech PDA Occluder works over time to close a patent ductus arteriosus (PDA). You may be considered if your PDA can be treated with this non-surgical device and you can return for follow-up visits.
MontrealAges Any age - NCT05304481RecruitingPhase 2
Activated immune cells after liver tumor removal for HCC
This Phase 2 study tests an immune-cell treatment (activated T lymphocytes) given after your liver cancer tumor has been fully removed. It aims to improve safety and reduce the chance of the cancer coming back in people with early-stage hepatocellular carcinoma.
Hualien City, TaiwanAges 20 years+ - NCT05232916RecruitingPhase 3
Vaccine for HER2-positive breast cancer after standard treatment
This trial tests a vaccine (GLSI-100) that may help prevent the return of HER2-positive breast cancer. It is given to patients who still had cancer cells after initial treatment with trastuzumab, or who had stage III disease and achieved a complete response.

Common questions
- Are there clinical trials for efficacy and safety?
- Yes. Clin2 currently lists 2,733 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.
