Clinical Trial Summary

The prognosis of Diffuse Large B cell Lymphoma (DLBCL) patients with an early relapse is dismal. Atezolizumab has shown promising activity in relapsed DLBCL patients. Toxicity data on atezolizumab are available for > 6000 patients and is manageable. The assumption of this study is that atezolizumab consolidation will result in higher disease free survival by eradicating minimal residual disease In melanoma and lung cancer consolidation immunotherapy after chemoradiotherapy has shown an increase in survival.

Description:

In high risk diffuse large B-cell lymphoma (DLBCL), International Prognostic Index (IPI)-score ≥ 3 21% of patients will relapse within 2-years after completion of R-CHOP induction treatment despite achieving a complete remission. Patient relapsing within a year after R-CHOP treatment have a very poor prognosis, even after second line chemotherapy, with only 15% of patients achieving a long remission. Therefore, additional therapy in first line treatment is required for these patients. The immune checkpoint inhibitor atezolizumab is a monoclonal antibody directed against the program death ligand 1 (PDL1). The PD1 and PDL1 inhibitors have shown excellent results in relapsed Hodgkin lymphoma and promising results in relapsed B-cell non Hodgkin lymphoma. Given the acceptable toxicity profile of atezolizumab, this study examines the efficacy and toxicity of atezolizumab as consolidation treatment after R-CHOP induction in DLBCL patients at high risk of relapse.

• History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis per chest computer tomography (CT) scan at screening.

• Patients with uncontrolled asthma or allergy, requiring systemic steroid treatment

• Regular treatment with corticosteroids within the 4 weeks prior to date of registration, unless administered for indications other than NHL at a dose equivalent to < 30 mg/day prednisone/prednisolone

• Any psychological, familial, sociological and geographical condition potentially hampering compliance with the study protocol and follow-up schedule

Prior treatment

• Prior treatment with Atezolizumab, or anti-programmed cell death protein-1 (anti PD-1) or PDL-1 antibodies.

• Prior treatment with CD137 agonists or immune checkpoint blockade therapies, including anti-CTLA4 therapeutic antibodies.

• Treatment with systemic immunostimulatory agents (including but not limited to IFN, interleukin [IL]-2) within 6 weeks or 5 half-lives of the drug, whichever is shorter, prior to Cycle 1, Day 1.
