Spots Global Cancer Trial Database for Pembrolizumab With Rituximab or Obinutuzumab in Treating Patients With Relapsed or Refractory Follicular Lymphoma or Diffuse Large B Cell Lymphoma

Study Description

Brief Summary: This phase II trial studies how well pembrolizumab with rituximab or obinutuzumab work in treating patients with follicular lymphoma or diffuse large B cell lymphoma that has come back (recurrent) or does not respond to treatment (refractory). 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. Rituximab and obinutuzumab are monoclonal antibodies. They bind to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving pembrolizumab with rituximab or obinutuzumab may help kill more cancer cells in patients with follicular lymphoma or diffuse large B cell lymphoma.

Detailed Description: OUTLINE: Patients are assigned to 1 of 2 arms. ARM I: INDUCTION: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive rituximab IV on days 1, 8, and 15 of cycle 1, and on day 1 of cycle 2. EXTENDED THERAPY: Patients with at least a partial response receive pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 3 weeks for up to 2 years (35 cycles) in the absence of disease progression or unacceptable toxicity. ARM II: INDUCTION: Patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 3 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive obinutuzumab IV on days 1, 8, and 15 of cycle 1, and on day 1 of cycle 2. EXTENDED THERAPY: Patients with at least a partial response receive pembrolizumab IV over 30 minutes on day 1. Cycles repeat every 3 weeks for up to 2 years (35 cycles) in the absence of disease progression or unacceptable toxicity. Patients with stable disease or better, who are experiencing clinical benefit in the judgment of the investigator, may receive obinutuzumab IV on day 1 of cycles 5, 9, 13, 17, 21, and 25. After completion of study treatment, patients are followed up for 90 days.
