Shanghai, Shanghai MunicipalityAges 18–70 - NCT06190782RecruitingPhase 3
Local therapy for limited metastatic esophageal cancer
This trial tests whether adding targeted radiation or other local treatments can help people with esophageal cancer that has spread to only a few spots (up to 4) after they've been treated with a PD-1 inhibitor. It aims to control the cancer better and improve outcomes.
ShanghaiAges 18 years+ - NCT06251115Recruiting
Study of QY-1-T for advanced HBV-related liver cancer
This study tests a new treatment called QY-1-T for people with advanced liver cancer related to hepatitis B. It is for patients who have already tried other standard treatments and have a certain genetic marker (HLA-A*11:01).
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06333561Recruiting
Combination therapy for infiltrative liver cancer
This trial tests a three-drug combination for a specific type of liver cancer called infiltrative hepatocellular carcinoma. It combines a liver-directed chemotherapy infusion (HAIC) with two oral and intravenous drugs (lenvatinib and a PD-1 inhibitor) to see if it works better than lenvatinib alone.
Beijing, Beijing MunicipalityAges 18–75 - NCT06359275RecruitingPhase 2
Combination therapy for locally advanced or recurrent pancreatic cancer
This trial tests a combination of immunotherapy (PD-1), chemotherapy, and a special type of radiation called PULSAR for patients with locally advanced pancreatic cancer or cancer that has come back only in the pancreas area. The goal is to see if this approach can shrink tumors or keep them from growing.

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.
