FDA Accepts and Grants Priority Review to BeiGene’s Zanubrutinib for Relapsed/Refractory Mantle Cell Lymphoma

CAMBRIDGE, Mass. and BEIJING, China, Aug. 21, 2019 (GLOBE NEWSWIRE) — BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biopharmaceutical company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s New Drug Application (NDA) for zanubrutinib for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. The FDA granted Priority Review for the NDA and has set a Prescription Drug User Fee Act (PDUFA) target action date of February 27, 2020. This follows the FDA’s Breakthrough Therapy designation for zanubrutinib in this setting earlier this year.

“Zanubrutinib, a potent and selective BTK inhibitor designed to maximize BTK occupancy and minimize off-target effects, has shown promise as a potential treatment for a number of B-cell malignancies,” said Jane Huang, M.D., Chief Medical Officer, Hematology, at BeiGene. “We are proud to have submitted our first NDA in the U.S., which has now been accepted and designated for Priority Review by the FDA for the treatment of patients with relapsed/refractory mantle cell lymphoma, an aggressive form of lymphoma. We are conducting a broad global clinical development program for zanubrutinib that currently consists of eight Phase 3 or potentially registration-enabling trials, including two head-to-head comparative trials, with approximately 1,500 patients treated across all programs.”

The NDA data package includes data from the global Phase 1/2 trial (NCT02343120) in patients with B-cell lymphomas and an aggregate of 123 patients in the multicenter Phase 2 trial of zanubrutinib in patients with relapsed or refractory (R/R) MCL in China (NCT03206970), as well as safety data on 641 patients from five clinical trials, and non-clinical data.

About Priority Review

The U.S. FDA grants Priority Review designation to applications for drugs that, if approved, would provide a significant improvement in safety or effectiveness of the treatment of serious conditions. Under Priority Review, the FDA aims to take action on the marketing application within six months of NDA acceptance, as compared to 10 months under standard review. Priority Review designation does not change the scientific/medical standard for approval or the quality of evidence necessary to support approval.

About Mantle Cell Lymphoma

Lymphoma is a diverse group of malignancies that originates from B-, T- or NK- cells. Mantle cell lymphoma (MCL) is typically an aggressive form of non-Hodgkin lymphoma (NHL) that arises from B-cells originating in the “mantle zone.” In the United States, about 70,800 new cases of NHL were estimated in 2014, with MCL representing about six percent (about 4,200 cases) of all new cases of NHL.i MCL usually has a poor prognosis, with a median survival of three to four years, although occasionally patients may have an indolent course.ii Frequently, MCL is diagnosed at a later stage of disease.

About Zanubrutinib

Zanubrutinib (BGB-3111) is an investigational small molecule inhibitor of Bruton’s tyrosine kinase (BTK), discovered by BeiGene scientists, that is currently being evaluated in a broad pivotal clinical program globally as a monotherapy and in combination with other therapies to treat various B-cell malignancies.

Clinical trials of zanubrutinib include the fully-enrolled Phase 3 ASPEN clinical trial in patients with Waldenström macroglobulinemia (WM) comparing zanubrutinib to ibrutinib, currently the only approved BTK inhibitor for WM; the fully-enrolled Phase 3 SEQUOIA trial comparing zanubrutinib with bendamustine plus rituximab in patients with treatment-naive (TN) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL); a pivotal Phase 2 trial in patients with relapsed/refractory (R/R) follicular lymphoma in combination with GAZYVA® (obinutuzumab); the Phase 3 ALPINE trial comparing zanubrutinib to ibrutinib in patients with R/R CLL/SLL; the Phase 3 trial in patients with untreated mantle cell lymphoma (MCL); the pivotal Phase 2 MAGNOLIA trial in patients with R/R marginal zone lymphoma (MZL); and a Phase 1 trial. BeiGene has completed two pivotal Phase 2 clinical trials of zanubrutinib in patients with R/R MCL and R/R CLL/SLL and the enrollment in the pivotal Phase 2 clinical trials in patients with WM.

The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for the treatment of patients with WM, and Breakthrough Therapy designation for the treatment of adult patients with MCL who have received at least one prior therapy. The New Drug Applications (NDAs) in China for R/R MCL and R/R CLL/SLL have been accepted by the China National Medical Products Administration (NMPA) and granted priority review.

Zanubrutinib is an investigational drug that has not been approved for any use in any country.
