Recruiting studies
- NCT04908566RecruitingPhase 2
PD-1 immunotherapy plus chemotherapy before and after gastric surgery
This trial studies whether adding a PD-1 immune therapy to chemotherapy around the time of surgery can improve outcomes for people with locally advanced stomach or stomach–esophagus junction cancer. It aims to better control the cancer before and reduce the chance it comes back after surgery.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT04997837RecruitingPhase 3
Adjuvant chemo with or without PD-1 for stomach cancer after surgery
This Phase 3 trial studies whether adding an immune medicine called PD-1 (given as an “inhibitor”) to standard chemotherapy and chemoradiation after stomach/GEJ cancer surgery can lower the risk of cancer coming back. You may qualify if you’ve had surgery removing the tumor and lymph nodes showed higher-risk disease.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05392413Recruiting
Predicting who benefits from PD-1 antibody for esophageal cancer
This study uses an “immune indicator model” to help predict how well a PD-1 antibody (a cancer-fighting immune drug) works when combined with chemotherapy for stage IV esophageal squamous cell cancer. If you qualify, you receive the treatment and the researchers also look for immune-related signs that may explain who benefits most.
GuangzhouAges 18–75 - NCT05980715RecruitingPhase 3
Comparing immunotherapy to radiation after successful treatment for head and neck cancer
This trial looks at whether giving an immunotherapy drug (a PD-1 inhibitor) after surgery is better than giving radiation therapy for people with advanced head and neck cancer who had a complete response to chemotherapy and immunotherapy before surgery. The goal is to prevent the cancer from coming back.
Guangzhou, GuangdongAges 18–65 - NCT05245474RecruitingPhase 2
Before-surgery chemoradiation plus PD-1 for locally advanced rectal cancer

It may offer a way to improve outcomes for those whose cancer has not progressed after 2-4 cycles of first-line treatment.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07841236RecruitingPhase 2
Blood test-guided immunotherapy for MSI-high colon cancer
This trial tests whether using a simple blood test (ctDNA) can help guide treatment with immunotherapy drugs (PD-1 inhibitors) for people with a specific type of colon cancer (MSI-high/dMMR). The goal is to see if this approach can improve outcomes and reduce side effects compared to standard care.
ShanghaiAges 18–75 - NCT06086457RecruitingPhase 3
Immunotherapy plus chemo with or without radiation for esophageal cancer
This trial tests whether adding radiation therapy to a standard treatment (immunotherapy plus chemotherapy) can help people with advanced esophageal cancer that has spread to up to two organs. The goal is to see if the combination improves outcomes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07786766RecruitingPhase 2
Pemigatinib plus immunotherapy for FGFR2-positive bile duct cancer
This study tests a combination of two drugs—pemigatinib (a targeted therapy) and a PD-1 inhibitor (an immunotherapy)—with or without chemotherapy, for people with advanced bile duct cancer that has an FGFR2 fusion or rearrangement. The goal is to see if this combination is more effective than standard treatment, and to find better ways to treat this type of cancer.
