Recruiting studies
- NCT05496036RecruitingPhase 2
Pembrolizumab before surgery for resectable Merkel cell cancer
This trial tests pembrolizumab (an immune therapy) given before surgery to shrink Merkel cell carcinoma and improve outcomes. Participants also have extra tumor biopsies to study biomarkers, which may help explain who benefits most.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05422794RecruitingPhase 1
Adding a new drug plus pembrolizumab to standard chemo for TNBC
This trial studies whether adding a new anti-cancer drug (ZEN-3694) and the immunotherapy drug pembrolizumab to standard chemotherapy (nab-paclitaxel) can work better for advanced triple-negative breast cancer. It’s testing safety first (Phase 1) and, for some patients, how well the treatment controls the cancer.
Boston, MassachusettsAges 18 years+ - NCT05431270RecruitingPhase 1/Phase 2
Test drug that targets CD73, alone or with immunotherapy
This early-stage study tests mavrostobart (an anti-CD73 antibody) to see what dose is safe and whether it can help shrink tumors. It’s studied by itself and also with a PD-1 immune therapy or chemotherapy, depending on your cancer type and prior treatments.
Huntersville, North CarolinaAges 18 years+ - NCT05357846RecruitingPhase 3
Check whether PD-1 treatment helps esophagus cancer before surgery
This Phase 3 trial tests whether adding a PD-1 medicine (sintilimab) to standard chemo-radiation before surgery improves outcomes for locally advanced esophageal squamous cell cancer. It may help by strengthening the immune response while shrinking the tumor before an operation.
Guangzhou, GuangdongAges 18–70 - NCT05345002RecruitingPhase 2
ATRA plus PD-1 therapy for IDH-mutant recurrent brain tumors
This trial studies whether adding all-trans retinoic acid (ATRA) to an anti–PD-1 immune therapy can slow recurrent or worsening IDH-mutant glioma. It may help by boosting the immune system’s attack on the tumor.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04966481RecruitingPhase 3
Palbociclib plus cetuximab versus cetuximab alone
This trial studies whether adding palbociclib to cetuximab works better than cetuximab by itself for head and neck cancer that is growing again after an anti–PD-1/PD-L1 treatment. It is for people whose tumor has a specific gene change (CDKN2A loss) and who have not had too many prior treatments.
Worthington, MinnesotaAges 18 years+ - NCT04643041Recruiting
Watch-and-wait after PD-1 for certain rectal cancer
This study looks at whether people with a very strong response to a PD-1 antibody can safely delay or avoid more standard rectal cancer treatment (a “watch-and-wait” approach). It may help some people avoid surgery, radiation, or ongoing treatment while still closely monitoring the cancer.
Guangzhou, GuangdongAges 18–80 - NCT04615988Recruiting
Vitamin D levels and hormone side effects from immune cancer therapy
This study looks at whether your blood vitamin D level is linked to hormone-related side effects caused by immune checkpoint cancer drugs. It may help doctors better predict who is at risk and how to monitor patients during treatment.
New York, New YorkAges 18 years+ - NCT04512534RecruitingPhase 2
Check-in study of immunotherapy plus another drug for lymphoma
This Phase 2 trial tests whether combining sintilimab (an immunotherapy) with chidamide (an anticancer “epigenetic” drug) can shrink peripheral T-cell lymphoma that has come back or didn’t respond. It’s for adults who have measurable lymphoma spots and can safely take both medicines.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04165772RecruitingPhase 2
Dostarlimab for locally advanced mismatch-repair deficient solid tumors
This Phase 2 trial studies dostarlimab (an immune therapy that targets PD-1) given before surgery or other initial treatment. It aims to shrink certain locally advanced cancers that have mismatch repair deficiency, potentially making treatment easier and improving outcomes.
Hartford, ConnecticutAges 18 years+ - NCT03259867RecruitingPhase 2
TACE plus immune therapy for liver or stomach cancer
This trial tests a combination treatment using a targeted liver procedure plus an immune “checkpoint” medicine to slow cancer growth. It may help people with advanced liver cancer (HCC) or metastatic stomach cancer when standard treatments have not worked.
Orange, CaliforniaAges 18–80 - NCT07699939RecruitingPhase 2
Perioperative immunotherapy plus chemo for advanced gastric cancer
This trial tests whether adding the immunotherapy drug HLX10 (serplulimab) to standard chemotherapy (S-1 plus oxaliplatin) before and after surgery can improve outcomes for patients with advanced gastric or gastroesophageal junction cancer that has a high level of PD-L1 protein.
Chiba, ChibaAges 18–80

Common questions
- Are there clinical trials for pd-1?
- Yes. Clin2 currently lists 300 recruiting pd-1 studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a pd-1 trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a pd-1 trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
