Study of Pembrolizumab (MK-3475) in Combination With Romidepsin

Found through the registry condition index, not selected as a treatment recommendation. This discovery collection was restricted to studies with posted results.

Phase: PHASE1, PHASE2
Status at capture: ACTIVE NOT RECRUITING
Registry last update: 2026-09-30

This phase I/II trial studies the side effects of pembrolizumab and romidepsin and to see how well they work in treating participants with peripheral T-cell lymphoma that has come back or that does not respond to treatment. 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. Romidepsin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and romidepsin may work better than pembrolizumab alone in treating participants with recurrent or refractory peripheral T-cell lymphoma.

Table 1 Adequate Organ Function Laboratory Values System Laboratory Value * Hematological * Absolute neutrophil count (ANC) ≥ 1000 /mcL * Platelets ≥100,000 / mcL. If bone marrow is involved, platelets should be at least 50K and ANC 750 / mcL * Hemoglobin ≥ 8g/dL without transfusion or EPO dependency (within 7 days of assessment) * Renal * Serum creatinine OR Measured or calculateda creatinine clearance (GFR can also be used in place of creatinine or CrCl) ≤1.5 X upper limit of normal (ULN) OR ≥60 mL/min for subject with creatinine levels \> 1.5 X institutional ULN * Hepatic * Serum total bilirubin ≤ 1.5 X ULN OR Direct bilirubin ≤ ULN for subjects with total bilirubin levels \> 1.5 ULN * AST (SGOT) and ALT (SGPT) ≤ 2.5 X ULN OR ≤ 5 X ULN for subjects with liver metastases * Albumin \> 2 mg/dL * Coagulation International Normalized Ratio (INR) or Prothrombin Time (PT) Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants aCreatinine clearance should be calculated per institutional standard. 7. Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. 8.

Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability. 9.

brief Summary: This phase I/II trial studies the side effects of pembrolizumab and romidepsin and to see how well they work in treating participants with peripheral T-cell lymphoma that has come back or that does not respond to treatment. 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. Romidepsin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and romidepsin may work better than pembrolizumab alone in treating participants with recurrent or refractory peripheral T-cell lymphoma.
detailed Description: Primary Objectives: 1. Evaluate the safety of pembrolizumab in combination with romidepsin. 2. Estimate the response rate of the combination therapy in refractory or recurrent PTCL Secondary Objectives: 1. Estimate progression free survival (PFS). 2. Estimate overall survival (OS). 3. Estimate complete response (CR) and duration of response (DOR). 4. Estimate the event-free survival (EFS) and the failure free survival (FFS) 5. Estimate the overall response rate (ORR) per Lugano criteria. Exploratory Objectives: 1. Assess activation of T-cells after treatment in peripheral blood and tumor microenvironment. 2. Correlate features of peripheral blood T-cell activation with toxicities, clinical response, and PFS. OUTLINE: Participants receive romidepsin intravenously (IV) over 4 hours on days 1 and 8 or day 8 of cycle 1 and days 1 and 8 of subsequent cycles and pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 21 days for up to 36 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, participants are followed up at 30 days and then every 12 weeks.
