Amivantamab plus chemo vs. standard chemo for left-sided colorectal cancer
This trial compares a new combination (amivantamab plus chemotherapy) with the standard treatment (cetuximab plus chemotherapy) as the first therapy for people with left-sided colorectal cancer that has spread.

Cema-cel for high-risk lymphoma after first treatment
This trial tests a new treatment called cema-cel for people with large B-cell lymphoma who are in remission after first-line therapy but still have tiny amounts of cancer detected by a sensitive blood test. The goal is to prevent the cancer from coming back.
Gilbert, ArizonaAges 18 years+ - NCT06509009RecruitingPhase 2
Nimotuzumab and TGP for first-line recurrent / metastatic nasopharyngeal cancer
This trial tests a combination of two drugs—nimotuzumab (a targeted therapy) and TGP (a chemotherapy)—as a first treatment for people whose nasopharyngeal cancer has returned or spread. The goal is to see if this combination can shrink tumors and help patients live longer.

Common questions
- Are there clinical trials for first-line?
- Yes. Clin2 currently lists 397 recruiting first-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 first-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 first-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.
