follicular lymphoma, a common B cell malignancy for which BTK inhibitors are not yet approved. We look forward to continuing the development of BGB-3111 as a potentially best-in-class BTK inhibitor for patients worldwide who suffer from hematological malignancies,” commented John V. Oyler, Founder, Chief Executive Officer, and Chairman of BeiGene.

“We believe that these two new pivotal trials are supported by our growing clinical experience with BGB-3111, in which over 600 patients have been dosed to date. With the newly initiated Phase 3 CLL/SLL trial, we aim to investigate whether BGB-3111 could be an effective treatment option for a broad population of CLL/SLL patients requiring initial treatment. The initiation of the pivotal trial in follicular lymphoma is an effort to determine whether the combination of BGB-3111 and obinutuzumab represents an effective treatment option for a high-unmet-need population of relapsed or refractory patients to potentially support the pursuit of accelerated or conditional approval of this regimen,” commented Jane Huang, M.D., Chief Medical Officer, Hematology.

Trial Design 

The Phase 3 trial in CLL/SLL is designed to compare BGB-3111 to BR and will be conducted in North America, Europe, Australia, New Zealand, and Asia. The study will enroll previously untreated CLL/SLL patients ineligible for intensive chemo-immunotherapy (i.e., fludarabine, cyclophosphamide, and rituximab), who will be divided into two cohorts. The first cohort is designed to include 420 patients without a 17p deletion (del17p),  who will be randomized in a 1:1 ratio to receive either BGB-3111 until progression or six cycles of BR. Crossover will be allowed in the BR arm upon progression. The primary endpoint will be progression-free survival (PFS), and secondary endpoints include overall response rate (ORR), duration of response (DOR), overall survival (OS), and patient-reported outcomes. Patients with del17p will be enrolled in a second cohort to receive BGB-3111 until progression and will be assessed for response and safety.
