Pembrolizumab in Combination With Chemotherapy for Patients With Untreated B Cell Lymphoma (NCT03995147)

Usually NOT eligible if any of the following apply:

• Exclusion Criteria:
• Positive urine pregnancy test within 72 hours prior to the initiation of study treatment. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137).
• Has received prior anti-lymphoma therapy, including radiation therapy, chemotherapy, targeted therapy, or immunotherapy. Note: Prior corticosteroid treatment (\<10 days in duration) to alleviate lymphoma-elated symptoms is permitted. Note: If participant received major surgery, he or she must have recovered adequately from complications from the intervention prior to starting study treatment.
• Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed.
• Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
• Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent, with the exception of short-term corticosteroid use to control lymphoma-related symptoms as outlined above) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
• Has a known additional malignancy that is progressing or has required active treatment within the past 2 years. Note: Participants with basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or carcinoma in situ (e.g. breast carcinoma, cervical cancer in situ) that have undergone potentially curative therapy are not excluded. Other exceptions may be permitted after discussion with the principal investigator.
• Has known active CNS involvement by lymphoma.
• Has a diagnosis of high-grade B cell lymphoma with MYC and BCL2 and/or BCL6 gene rearrangements (double hit lymphoma), primary mediastinal lymphoma, gray zone lymphoma, composite lymphoma, or previously-untreated low-grade lymphoma with disease transformation to DLBCL.
• Has severe hypersensitivity (≥ grade 3) to pembrolizumab and/or any of its excipients.
• Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
