BeiGene Announces First Patient Dosing for Investigational BTK Inhibitor BGB-3111 in China

WALTHAM, Mass., July 05, 2016 (GLOBE NEWSWIRE) -- BeiGene, Ltd. (NASDAQ:BGNE), a clinical-stage biopharmaceutical company focused on developing molecularly targeted and immuno-oncology drugs for the treatment of cancer, today announced the dosing of the first patient in China in a Phase I clinical trial of BGB-3111, an investigational Bruton’s tyrosine kinase (BTK) inhibitor for the treatment of various B-cell malignancies.

“We believe BGB-3111 is the first BTK inhibitor being developed in China under the Category 1.1 domestic regulatory pathway to enter the clinic and to present clinical data. This agent has been in clinical testing since August 2014 in Australia, New Zealand, Korea and the United States, and we are hopeful that data from this dose-escalation study will pave the way to rapid development of BGB-3111 in China,” commented John V. Oyler, Founder, Chief Executive Officer, and Chairman.

The Phase I multi-center, open label clinical trial of BGB-3111 is designed to assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of this agent in Chinese patients with B-cell malignancies, and to determine the recommended Phase II dose in Chinese patients. Professor Jun Zhu, MD, a medical oncologist at the Beijing Cancer Hospital will be the leading principal investigator of the study.

About BGB-3111

BGB-3111 is an investigational small molecule inhibitor of Bruton’s tyrosine kinase (BTK) that has demonstrated higher selectivity against BTK and higher exposure than ibrutinib, the only BTK inhibitor currently approved by the U.S. Food and Drug Administration and the European Medicines Agency. In addition, available clinical data with BGB-3111 demonstrated sustained 24-hour BTK occupancy in both the blood as well as the lymph node.
