Study of posaconazole with immunotherapy and chemo for triple-negative breast cancer
This trial tests if adding posaconazole (an antifungal drug) to standard immunotherapy and chemotherapy before breast cancer surgery works better than just the standard treatment. It is for people with newly diagnosed, early-stage triple-negative breast cancer.
Jinan, ShandongAges 18–70 - NCT06958432RecruitingPhase 2/Phase 3
Short-course radiation plus chemo and immunotherapy for rectal cancer
This trial tests a treatment plan that uses a short course of radiation to the lymph nodes-sparing area, followed by chemotherapy and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of mid or low rectal cancer (pMMR/MSS). The goal is to see if this approach can shrink the tumor and improve outcomes without needing extensive surgery.
Guangzhou, GuangdongAges 18–75 - NCT07042672Recruiting
Therapy and medication for binge eating in obesity
This trial tests whether a medication (liraglutide) plus behavioral counseling helps people with severe obesity and binge-eating disorder reduce binge episodes, lose weight, and improve coping. Participants will receive either liraglutide or placebo, along with group therapy sessions.
Bergen, VestlandAges 18–65 - NCT07053072RecruitingPhase 1
PD-1 mRNA vaccine for advanced liver cancer

Common questions
- Are there clinical trials studying S-1?
- Yes. Clin2 currently lists 796 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.
