Study of oral health in people with Wilson’s disease
This study compares oral (mouth and teeth) health in people with Wilson’s disease versus people without it. It aims to see whether Wilson’s disease is linked to specific dental and imaging findings, which could help with future prevention and care.
Ivry-sur-SeineAges 18 years+ - NCT05447923Recruiting

BeekAges 3–10 - NCT05454488RecruitingPhase 2
Study focal freezing for intermediate-risk prostate cancer
This trial tests whether freezing only the cancer area in the prostate (focal cryotherapy) can control intermediate-risk prostate cancer. It aims to limit treatment to one tumor focus while closely checking results with targeted and follow-up testing.
Houston, TexasAges 18 years+ - NCT05462613RecruitingPhase 2/Phase 3
Regorafenib plus aspirin then standard chemo for metastatic bowel cancer
This trial tests whether adding regorafenib and low-dose aspirin before standard chemotherapy can slow metastatic colorectal cancer after it has progressed on prior treatment. It may help by trying a different cancer-fighting approach earlier, followed by the usual chemo plan.

Common questions
- Are there clinical trials for questionnaire?
- Yes. Clin2 currently lists 1,164 recruiting questionnaire 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 questionnaire 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 questionnaire 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.
