Wenzhou, ZhejiangAges 18–70 - NCT06602622RecruitingPhase 4
Weight change study for people with HIV switching to DOR/3TC/TDF
This study tests whether switching your HIV medication to a combination called DOR/3TC/TDF can help with weight changes that started after taking another type of HIV drug (integrase inhibitor). It is for people who have gained weight unintentionally and want to see if a different medication helps manage it.
Mexico City, AzcapotzalcoAges 18–80 - NCT05584397Enrolling by invitation
Compare immune activity and HIV hidden reservoir on two treatments
This study compares how active the immune system is and how large the “hidden” HIV reservoir is in people on two different HIV treatment types. It may help researchers understand whether staying on a tenofovir-containing regimen leads to better control of HIV hiding in the body.
Seattle, WashingtonAges 18–65 - NCT07464756RecruitingPhase 2
Study of SHR-1701 and apatinib with chemo before stomach cancer surgery
This trial tests whether adding SHR-1701 (an immunotherapy) with or without apatinib (a targeted therapy) to standard chemotherapy before surgery can help treat gastric cancer. It is for people with stomach or gastroesophageal junction cancer that has spread to nearby lymph nodes but is still removable.
Nanjing, JiangsuAges 18 years+ - NCT06814080Recruiting

Common questions
- Are there clinical trials studying S-1?
- Yes. Clin2 currently lists 802 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.
