A Safety and Pharmacology Study of Atezolizumab (MPDL3280A) Administered With Obinutuzumab or Tazemetostat in Participants With Relapsed/Refractory Follicular Lymphoma and Diffuse Large B-cell Lymphoma

Completed · Phase 1

Conditions studied: Lymphoma

In brief

This open-label, multicenter, global study is designed to assess the safety, tolerability, preliminary efficacy, and pharmacokinetics of intravenous atezolizumab (MPDL3280A) and obinutuzumab in participants with refractory or relapsed follicular lymphoma (FL) or atezolizumab and obinutuzumab or tazemetostat administered in participants with refractory or relapsed diffuse large B-cell lymphoma (DLBCL). The anticipated duration of this study is approximately 4.5 years.

• Archival tumor tissue
• For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 90 days after the last dose of atezolizumab or 18 months after the last dose of obinutuzumab, whichever is longer
• For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures and agreement to refrain from donating sperm

You may not qualify if…

• Uncontrolled hypercalcemia or symptomatic hypercalcemia requiring continued use of bisphosphonate therapy or denosumab
• History of severe allergic or anaphylactic reactions to monoclonal antibody therapy
• Has had prior exposure to tazemetostat or other inhibitor(s) of enhancer of zeste homolog 2 (EZH2)

• Pregnant and lactating women
• History of autoimmune disease
• Participants with history of confirmed progressive multifocal leukoencephalopathy (PML)
• Participants with prior allogeneic bone marrow transplantation or prior solid organ transplantation
• History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis per chest CT scan at screening. History of radiation pneumonitis in the radiation field (fibrosis) is allowed
• Positive test for Human Immunodeficiency Virus (HIV)

• Prior treatment with CD137 agonists or immune checkpoint blockade therapies, including anti-CTLA4, anti-PD-1, and anti-PD-L1 therapeutic antibodies
• Treatment with systemic immunostimulatory agents (including but not limited to interferon, interleukin-2) within 6 weeks or 5 half-lives of the drug, whichever is shorter, prior to Cycle 1, Day 1
• Treatment with systemic immunosuppressive medications, including but not limited to prednisone, cyclophosphamide, azathioprine, methotrexate, thalidomide, and anti-tumor necrosis factor (anti-TNF) agents within 2 weeks prior to Cycle 1, Day 1; inhaled corticosteroids and mineralocorticoids are allowed
• Participants with active tuberculosis (TB) will be excluded from the clinical trial
