How PD-1 antibody therapy affects immune function in cancer
This trial is studying how PD-1 antibody therapy (a type of immunotherapy that helps your immune system fight cancer) affects the immune system in people with various cancers. It may be a good fit if you have a confirmed cancer diagnosis and have your medical records and immune test results available.

New hormone treatment for polycystic ovary syndrome
This study tests a new medication that combines two hormone-like drugs to treat polycystic ovary syndrome (PCOS), a condition affecting ovulation and hormone balance. The trial aims to see if this dual-action drug can improve irregular periods and other PCOS symptoms better than current treatments.
Shanghai, Shanghai MunicipalityAges 18–40 - NCT07605572Recruiting
GLP-1 drugs and dry eye disease in type 2 diabetes
This study tests whether a diabetes and weight-loss medication called GLP-1 receptor agonists affects dry eye disease. Researchers want to see if this medication helps or worsens dry eyes in people with type 2 diabetes and obesity.
AthensAges 18 years+ - NCT07595367RecruitingPhase 2
BBD-1 immune therapy for IgA vasculitis
This trial tests a new drug called BBD-1 that may help treat IgA vasculitis, a condition where your immune system attacks small blood vessels, causing a purple rash and organ damage. The study measures how well BBD-1 reduces symptoms and side effects.

Common questions
- Are there clinical trials studying S-1?
- Yes. Clin2 currently lists 792 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.
