BeiGene Announces Initiation of Pivotal Study in China with BTK Inhibitor BGB-3111 in Patients with Relapsed or Refractory CLL/SLL

BEIJING, China I March 09, 2017 I BeiGene, Ltd. (BGNE), a clinical-stage biopharmaceutical company developing molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced the dosing of the first patient in a pivotal clinical trial of BGB-3111, an investigational Bruton’s Tyrosine Kinase (BTK) inhibitor, in Chinese patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). BGB-3111 is also currently being evaluated in a pivotal Phase II clinical trial in Chinese patients with relapsed or refractory mantle cell lymphoma (MCL) and a global Phase III clinical trial in comparison with ibrutinib for the treatment of patients with Waldenström’s Macroglobulinemia.

“We are pleased to announce the start of the second pivotal clinical trial of BGB-3111 in China. With this trial, we hope to demonstrate BGB-3111’s efficacy and safety in Chinese patients with CLL/SLL and build upon the promising data we presented at last year’s ASH annual meeting from the global Phase I trial of BGB-3111 in patients with CLL/SLL,” commented John V. Oyler, Founder, Chief Executive Officer, and Chairman.

“We hope that our pivotal program for BGB-3111 in China, with trials currently underway in MCL and CLL/SLL, will allow us to broadly and rapidly develop BGB-3111 for the benefit of cancer patients in China,” commented Lai Wang, Ph.D., Head of China Development.

The Phase II single-arm, open-label, multi-center study is designed to investigate the efficacy and safety of BGB-3111 in patients with relapsed or refractory CLL/SLL. The trial’s primary endpoint is the objective response rate, defined as achievement of either a partial response or complete response at any time on study drug. Secondary endpoints include progression free survival, duration of response, time to response, safety, and tolerability. Professor Jianyong Li of the Jiangsu Province Hospital, the first Affiliated Hospital with Nanjing Medical University, is the lead principal investigator of the trial.

About BGB-3111

BGB-3111 is a potent and highly selective investigational small molecule inhibitor of BTK. BGB-3111 has demonstrated higher selectivity against BTK than ibrutinib (the only BTK inhibitor currently approved by the U.S. Food and Drug Administration and the European Medicines Agency) based on biochemical assays, higher exposure than ibrutinib based on their respective Phase I experience, and sustained 24-hour BTK occupancy in both the blood and the lymph node.
