Pembrolizumab in Treating Participants With Unresectable Thymoma or Thymic Cancer

Is NCT03295227 recruiting? Yes, currently enrolling (May 2026). This Phase 1 trial studies Pembrolizumab for stage iii thymoma ajcc v8.

Phase 1RecruitingM.D. Anderson Cancer CenterNCT03295227Data as of May 2026

Treatment: PembrolizumabThis phase I trial studies the sides effects and best dose of pembrolizumab in treating participants with thymoma or thymic cancer that cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Prior therapy

Cannot have received: anti-PD-1 therapy

Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.

Cannot have received: anti-cancer monoclonal antibody

Exception: within 4 weeks prior to study day 1 or not recovered from adverse events

Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study day 1 or who has not recovered (i.e., ≤ grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.

Cannot have received: chemotherapy

Exception: within 2 weeks prior to study day 1 or not recovered from adverse events (≤ grade 1 or at baseline); ≤ grade 2 neuropathy allowed
