Official title
Phase II Study of Anti-CD20 Antibody Therapy Plus Pembrolizumab (MK-3475) in Subjects With Relapsed Follicular and Diffuse Large B-Cell Lymphoma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
