BeiGene Presents Long-Term Efficacy And Safety Results From Three Pivotal Trials Of BRUKINSA® (Zanubrutinib) And Tislelizumab At EHA2021

CAMBRIDGE, Mass. & BEIJING--(BUSINESS WIRE)-- BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a global biotechnology company focused on developing and commercializing innovative medicines worldwide, today announced long-term follow-up results from three pivotal trials in its hematology program at the 26th European Hematology Association 2021 (EHA2021) Virtual Congress, including a pivotal Phase 2 trial of its anti-PD-1 antibody tislelizumab in relapsed or refractory (R/R) classical Hodgkin’s lymphoma (cHL) in an oral presentation, and two pivotal Phase 2 trials of its BTK inhibitor BRUKINSA® (zanubrutinib) in R/R mantle cell lymphoma (MCL) and in R/R chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) in poster presentations.

“We are excited to see the long-term clinical benefits tislelizumab and BRUKINSA provided for patients in these pivotal trials, which supported the approvals in the relapsed or refractory setting of cHL and CLL or SLL in China, and MCL in both the U.S. and China,” said Jane Huang, M.D., Chief Medical Officer, Hematology at BeiGene. “With additional treatment exposure, tislelizumab achieved a higher complete response rate with no new safety signals identified, and the deep responses translated to impressive progression-free survival outcomes. And in the two BRUKINSA trials, our selective next-generation BTK inhibitor showed sustained deep responses and remained well-tolerated in these patients. As BeiGene continues to expand our global footprint, we plan to work to bring these important therapies to more patients in need.”

Long-Term Follow-up Results of Tislelizumab in R/R cHL

Oral presentation; Abstract code: S207

The 34-month follow-up results from the single-arm, multicenter, pivotal Phase 2 trial (NCT03209973) demonstrated that tislelizumab was active and generally well-tolerated as a treatment for patients with R/R cHL. Results from this pivotal Phase 2 trial supported the conditional approval of tislelizumab for the treatment of patients with cHL who received at least two prior therapies in China in December 2019.

“Despite the progress made by previous checkpoint inhibitors in R/R cHL treatment, only a minority of patients can achieve a CR,” said Yuqin Song, M.D., Ph.D., chief physician and deputy director of the Lymphoma Department at Beijing Cancer Hospital and a principal investigator of the trial. “As demonstrated in the 34-month follow-up results, tislelizumab achieved deep, durable, and consistent responses in these patients regardless of subgroup characteristics, and nearly 70% of patients reached complete remission. We are hopeful that this NMPA-approved immunotherapy can bring continued clinical benefits to patients with R/R cHL in China.”
