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.

Study of focused radiation after PD-1 treatment helped non-lung cancer
This observational study looks at how stereotactic (high-precision) radiation works for advanced non-small cell lung cancer that is stable after PD-1 antibody treatment (sometimes with chemotherapy). It may help doctors better understand which patients benefit from this next treatment step and what side effects to expect.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05700721RecruitingPhase 2
Niraparib and dostarlimab for cancer with growing brain spots
This trial studies whether the medicines niraparib and dostarlimab can slow advanced cancers that have active, growing brain metastases. It is meant for people whose brain tumors can be measured on MRI and who have had at least one previous treatment.
Houston, TexasAges 18 years+ - 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 - NCT06031636Recruiting

ShanghaiAges 18 years+ - 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.

Short radiation and chemo-immunotherapy for early rectal cancer after local surgery
This trial tests a combination of short-course radiation, chemotherapy (CapeOx), and an immunotherapy drug (PD-1 inhibitor) for people with early-stage rectal cancer who have had a local excision but are at high risk of the cancer coming back. The goal is to avoid more extensive surgery while still effectively treating the cancer.
ShanghaiAges 18–75 - NCT06472713RecruitingPhase 2
Liposomal mitoxantrone with immunotherapy for advanced nasopharyngeal cancer
This trial tests a combination of a chemotherapy drug (mitoxantrone liposome) with an immunotherapy (PD-1 blocker) for people whose nasopharyngeal cancer has come back or spread and hasn't responded to previous treatments. The goal is to see if this combination can shrink tumors or slow cancer growth.

Study of 9MW2821 for advanced triple-negative breast cancer
This trial tests a new drug, 9MW2821 (sometimes with a PD-1 inhibitor), for people with advanced triple-negative breast cancer. It may be an option if you've already tried standard treatments or haven't started any yet.

Common questions
- Are there clinical trials studying PD-1 inhibitor?
- Yes. Clin2 currently lists 199 recruiting studies that include PD-1 inhibitor, 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 PD-1 inhibitor 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 PD-1 inhibitor 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 PD-1 inhibitor or a specific trial is right for you.
