The CLL filing is supported by two global Phase 3 trials of BRUKINSA in chronic lymphocytic leukemia covering both treatment-naïve and relapsed or refractory patient populations

BRUKINSA was granted approval by the European Commission for the treatment of Waldenström’s macroglobulinemia in November 2021

BeiGene (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global, science-driven biotechnology company focused on developing innovative and affordable medicines to improve treatment outcomes and access for patients worldwide, today announced that the European Medicines Agency (EMA) has accepted for review two new indication applications for its BTK inhibitor BRUKINSA^® (zanubrutinib) for the treatment of patients with chronic lymphocytic leukemia (CLL) and for the treatment of patients with marginal zone lymphoma (MZL).

“As a BTK inhibitor designed to maximize BTK occupancy and minimize off-target binding, BRUKINSA demonstrated improvements in ORR and advantages in overall cardiac safety compared to ibrutinib in the ALPINE study in patients with relapsed or refractory CLL. Together with results from the SEQUOIA study in front-line CLL, BRUKINSA has the potential to become a preferred treatment option for patients with CLL and MZL in the European Union,” commented Peter Hillmen, MBChB, Ph.D., Professor of Experimental Haematology at University of Leeds, and principal investigator of the ALPINE trial.

In November 2021, BRUKINSA received its first approval in the European Union (EU) for the treatment of adult patients with Waldenström’s macroglobulinemia (WM) who have received at least one prior therapy or for the first-line treatment of patients unsuitable for chemo-immunotherapy.

“Following BRUKINSA’s recent EU approval in WM, we are pleased that BRUKINSA is now under review for two more indications—CLL and MZL. We are confident in the broad clinical evidence from its global clinical development program and hope to bring this next-generation BTK inhibitor to CLL and MZL patients in the EU,” said Jane Huang, M.D., Chief Medical Officer of Hematology at BeiGene.

The application for CLL is based on data included from two global Phase 3 trials of BRUKINSA in CLL—ALPINE (NCT03734016) comparing BRUKINSA to ibrutinib in relapsed or refractory (R/R) patients and SEQUOIA (NCT03336333) comparing BRUKINSA to bendamustine and rituximab in treatment-naïve (TN) patients. These two studies enrolled patients from a total of 17 countries, including the United States, China, Australia, New Zealand and multiple countries in Europe.

Results from the ALPINE trial and the SEQUOIA trial were reported at the 26^th European Hematology Association (EHA2021) Virtual Congress in June 2021 and at the 63^rd American Society for Hematology (ASH) Annual Meeting in December 2021, respectively.

The application for MZL is based on efficacy results from two single-arm clinical trials—MAGNOLIA (NCT03846427), a global pivotal Phase 2 trial in patients with R/R MZL who received at least one anti-CD20-based regimen, and BGB-3111-AU-003 (NCT02343120), a global Phase 1/2 trial. These two studies enrolled patients from a total of nine countries, including sites in the United States, China, Europe, Australia, and New Zealand. Results from the MAGNOLIA trial were reported at the 62^nd ASH Annual Meeting in December 2020.

Added Gerwin Winter, Senior Vice President, Head of Commercial, Europe at BeiGene, “We are proud of the progress BeiGene has made in Europe over the past year, with a growing team across the continent. The acceptance of our applications for MZL and CLL bring us a step closer to broadening access to patients.”

About Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma

Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in Western countries, accounting for approximately one third of all leukemia cases.^1,2 In 2020, an estimated 30,000 new CLL patients were diagnosed in Europe.^2,3 CLL begins in cells that become certain white blood cells (lymphocytes) in the bone marrow but then go into the blood. Proliferation of cancer cells (leukemia) in the marrow result in reduced ability to fight infection and spread into the blood, which affects other parts of the body including the lymph nodes, liver and spleen.^4,5,6 The BTK pathway is a known route that signals malignant B cells and contributes to the onset of CLL.⁷ Small lymphocytic lymphoma (SLL) is a non-Hodgkin’s lymphoma affecting the B-lymphocytes of the immune system, which shares many similarities to CLL but with cancer cells found mostly in lymph nodes.⁸

About Marginal Zone Lymphoma

Marginal Zone lymphoma (MZL) is a group of indolent non-Hodgkin’s lymphomas (NHL) that begin in the marginal zones of lymph tissue, representing approximately 5-15 percent of all NHL cases in the Western world.⁹ There are three different subtypes of MZL: extranodal marginal zone B-cell lymphoma or mucosa-associated lymphoid tissue (MALT) which is most common; nodal marginal zone B-cell lymphoma which develops in the lymph nodes and is rare; and splenic marginal zone B-cell lymphoma which develops in the spleen, bone marrow, or both and is the rarest form of the disease.¹⁰

About BRUKINSA

BRUKINSA is a small molecule inhibitor of Bruton’s tyrosine kinase (BTK) discovered by BeiGene scientists that is currently being evaluated globally in a broad clinical program as a monotherapy and in combination with other therapies to treat various B-cell malignancies. Because new BTK is continuously synthesized, BRUKINSA was specifically designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared to other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease relevant tissues.

BRUKINSA is supported by a broad clinical program which includes more than 3,900 subjects in 35 trials across 28 markets. In November 2021, the European Commission approved BRUKINSA for the treatment of adult patients with Waldenström’s macroglobulinemia (WM) who have received at least one prior therapy or for the first-line treatment of patients unsuitable for chemo-immunotherapy. To date, BRUKINSA has received more than 20 approvals covering more than 40 countries and regions, including the United States, China, the EU and Great Britain, Canada, Australia and additional international markets. Currently, more than 40 additional regulatory submissions are in review around the world.

BeiGene is committed to advancing best- and first-in-class clinical candidates internally or with like-minded partners to develop impactful and affordable medicines for patients across the globe. We have a growing R&D and medical affairs team of approximately 2,900 colleagues dedicated to advancing more than 100 clinical trials that have involved more than 14,500 subjects. Our expansive portfolio is directed predominantly by our internal colleagues supporting clinical trials in more than 45 countries and regions. Hematology-oncology and solid tumor targeted therapies and immuno-oncology are key focus areas for the Company, with both mono- and combination therapies prioritized in our research and development. BeiGene currently has three approved medicines discovered and developed in our own labs: BTK inhibitor BRUKINSA in the United States, China, the EU and U.K., Canada, Australia and additional international markets; and the non-FC-gamma receptor binding anti-PD-1 antibody tislelizumab as well as the PARP inhibitor pamiparib in China.

BeiGene also partners with innovative companies who share our goal of developing therapies to address global health needs. We commercialize a range of oncology medicines in China licensed from Amgen, Bristol Myers Squibb, EUSA Pharma and Bio-Thera. We also plan to address greater areas of unmet need globally through our other collaborations including with Mirati Therapeutics, Seagen, and Zymeworks.

In January 2021 BeiGene and Novartis announced a collaboration granting Novartis rights to co-develop, manufacture, and commercialize BeiGene’s anti-PD1 antibody tislelizumab in North America, Europe, and Japan. Building upon this productive collaboration, including a biologics license application (BLA) under FDA review, BeiGene and Novartis announced an option, collaboration and license agreement in December 2021 for BeiGene’s TIGIT inhibitor ociperlimab that is in Phase 3 development. Novartis and BeiGene also entered into a strategic commercial agreement through which BeiGene will promote five approved Novartis Oncology products across designated regions of China.
