Hangzhou, ZhejiangAges 18–75 - NCT07359040Recruiting
Testing a new drug before surgery for lung cancer
This trial studies whether a new drug called Ivonescimab can improve outcomes when given before surgery for non-small cell lung cancer. It may help shrink tumors and make them easier to remove.
Beijing, Beijing MunicipalityAges Any age - NCT02821013RecruitingPhase 3
Testing how long to take PD-1 therapy for melanoma
This trial studies whether people with metastatic melanoma should take PD-1 immunotherapy continuously or only for a limited time. It aims to find a schedule that keeps the cancer under control while possibly reducing treatment burden.
Victoria, MilduraAges 18 years+ - NCT07404332RecruitingPhase 1
Combination therapy for tumors resistant to immunotherapy
This trial tests a combination of two drugs (5-Azacitidine and a PD-1/PD-L1 inhibitor) for people whose solid tumors stopped responding to standard PD-1/PD-L1 immunotherapy alone. The goal is to see if this new combination can help shrink the tumor or slow its growth.

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.
