TianjinAges 18 years+ - NCT03886662RecruitingPhase 1/Phase 2
LB-100 for low-risk MDS after prior treatment failure
This Phase 1/2 trial studies LB-100 in adults with low or intermediate-1 risk myelodysplastic syndromes (MDS). It may help by improving blood counts or disease control in people whose prior treatments have not worked or stopped working.
Tampa, FloridaAges 18 years+ - NCT04453826RecruitingPhase 3
Test PD-1 plus chemo-radiation for high-risk nasopharyngeal cancer
This Phase 3 trial tests whether adding a PD-1 immunotherapy (given with chemotherapy and radiation, and also after) can improve outcomes for people with high-risk nasopharyngeal cancer. It may help by strengthening the immune system’s attack on the cancer alongside standard treatment.
Guangzhou, GuangdongAges 18–70 - NCT04453813RecruitingPhase 3
Immunotherapy with chemoradiation for recurring nasopharyngeal cancer
This phase 3 trial tests whether adding toripalimab (an immunotherapy medicine) to standard chemo-radiation works better for treating nasopharyngeal cancer that has come back and cannot be removed by surgery. It aims to improve control of the cancer after it returns.
Guangzhou, GuangdongAges 18–70 - NCT04483076RecruitingPhase 3
Chemo before stomach surgery with different cycles
This trial studies whether giving oxaliplatin plus S-1 (SOX) chemotherapy before stomach surgery works best when given for different cycle lengths. It may help shrink stage III gastric cancer before a standard D2 gastrectomy and improve outcomes.
Beijing, Beijing MunicipalityAges 18–70 - NCT04778956RecruitingPhase 3
Toripalimab plus surgery vs surgery alone for recurring throat cancer
This trial tests whether adding toripalimab (an immune therapy) to surgery helps people with recurrent nasopharyngeal cancer live longer or control the cancer better than surgery alone. You may qualify if your recurrence can be fully removed by surgery and it came back after a certain amount of time.
Guangzhou, GuangdongAges 18–70 - NCT05178277Recruiting
Alpha-1 antitrypsin deficiency registry study
This study collects health information from people who have alpha-1 antitrypsin deficiency. It may help doctors better understand the condition and improve care over time.

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.
