Phase II Trial of Venetoclax and Rituximab as Initial Therapy in Older Patients With Mantle Cell Lymphoma

The proposed study is an open-label, single arm phase II study of venetoclax in combination with rituximab in patients over the age of 60 with previously untreated mantle cell lymphoma. The primary objective of the trial is to determine whether the combination of venetoclax with rituximab in this patient population yields a clinically acceptable proportion of overall responses (ORR, assessed by PET/CT with Lugano criteria) without chemotherapy.
