Shanghai, Shanghai MunicipalityAges 18 years+ - NCT07555483RecruitingPhase 3
Weekly injection vs IV infusion for alpha-1 antitrypsin deficiency
This trial tests whether a new weekly injection form of alpha-1 antitrypsin replacement therapy (a protein your body lacks) works as well as the standard IV infusion you may currently receive. The goal is to offer a more convenient treatment option for people with alpha-1 antitrypsin deficiency (a genetic lung condition).
Birmingham, AlabamaAges 18–80 - NCT04988555RecruitingPhase 1/Phase 2
Study of an investigational drug for high-risk acute leukemia
This Phase 1/2 study tests enzomenib (DSP-5336) in people with relapsed or hard-to-treat acute leukemia (and, in some places, certain other blood cancers). The goal is to see how the drug works and how safe it is, especially for leukemia cases with specific genetic changes (KMT2A/MLL or NPM1).
Newport Beach, CaliforniaAges 12 years+ - NCT05029726RecruitingPhase 4
Numbing medicine during back surgery to reduce pain
This trial tests a regional anesthesia (numbing medicine given near nerves) during minimally invasive lumbar spine surgery. The goal is to see if it helps control pain around surgery and improves recovery comfort.
Chicago, IllinoisAges 18–80 - NCT05033392RecruitingPhase 2
PD-1 therapy plus chemotherapy before stomach cancer surgery
This Phase 2 trial tests whether adding a PD-1 antibody (JS001/toripalimab) to chemotherapy before surgery can improve outcomes for people with locally advanced stomach or gastroesophageal junction adenocarcinoma. It aims to help shrink the tumor and make surgery more effective.

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.
