RiMO-301 plus radiation with PD-1 therapy for head-neck cancer
This trial studies RiMO-301 injection combined with palliative radiation and a PD-1 immune therapy (pembrolizumab or nivolumab) for head and neck cancer that cannot be fully removed. It aims to see whether this approach can shrink tumors and improve outcomes safely.
Chicago, IllinoisAges 18 years+ - NCT05862064RecruitingPhase 3
Adding an immune drug and anti-blood-vessel treatment to chemo
This study tests whether adding an immune therapy (a PD-1 antibody) plus a blood-vessel–blocking treatment to standard chemo improves outcomes for people with surgically treated triple-negative breast cancer. Everyone gets chemotherapy, but some will also get the added drugs to try to reduce cancer coming back.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05862012RecruitingPhase 1
Test drug ISB 2001 in multiple myeloma patients who relapsed
This Phase 1 study tests ISB 2001, a new investigational treatment, in people with multiple myeloma that has come back or not responded to prior treatment. It mainly focuses on safety and whether the drug can be given effectively.

Common questions
- Are there clinical trials studying S-1?
- Yes. Clin2 currently lists 801 recruiting studies that include S-1, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a S-1 trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is S-1 an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether S-1 or a specific trial is right for you.
