MS progression and immune cells after bone marrow transplant and other therapies
This study looks at how well different treatments, including bone marrow transplant, alemtuzumab, ocrelizumab, and ofatumumab, work for people with relapsing-remitting MS who have active disease. It will help doctors understand which therapy might slow disease progression best.
MilanAges 18 years+ - NCT06293014RecruitingPhase 2
TAS-102 with bevacizumab for colorectal cancer maintenance
This trial tests a combination of two drugs, TAS-102 and bevacizumab, as a follow-up maintenance treatment for people with advanced colorectal cancer. The goal is to see if this treatment can keep the cancer from growing after initial chemotherapy and bevacizumab therapy.

Common questions
- Are there clinical trials for second line?
- Yes. Clin2 currently lists 113 recruiting second line 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 second line 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 second line 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.
