Study Summary

This phase I/II trial studies the side effects and best dose of pralatrexate when given together with pembrolizumab and how well they work in treating patients with peripheral T-cell lymphomas that has come back after a period of improvement or has not responded to treatment. Pralatrexate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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. Giving pembrolizumab and pralatrexate may work better in treating patients with peripheral T-cell lymphomas.

Primary Outcome

Dose limiting toxicities (DLT) were defined as one of the AEs in Protocol Section 5.5 that at least possibly related to study treatment. The DLT observation period was 2 cycles of therapy, from the start of Cycle 1 through the start of Cycle 3. Toxicities were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE, Version 5.0).
