BeiGene Receives European Commission Approval for BRUKINSA® (zanubrutinib) for the Treatment of Adults with Marginal Zone Lymphoma

BRUKINSA is the first and only Bruton’s Tyrosine Kinase (BTK) inhibitor for marginal zone lymphoma approved in the European Union

BeiGene (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global biotechnology company, today announced that the European Commission (EC) has granted marketing authorization of BRUKINSA^® (zanubrutinib) for the treatment of adult patients with relapsed/refractory (R/R) marginal zone lymphoma (MZL) who have received at least one prior anti-CD20-based therapy. The approval is applicable to all 27 member states of the European Union (EU), plus Iceland and Norway. BeiGene is focused on developing innovative and affordable oncology medicines to improve treatment outcomes and access for patients worldwide.

Notably, the EC granted an additional year of marketing protection because the data submitted for the therapeutic indication demonstrated a significant clinical benefit for BRUKINSA in comparison with existing therapies.

“We are proud of what this approval means for European MZL patients, who previously did not have an approved BTK inhibitor as a treatment option for this rare hematological malignancy,” said Mehrdad Mobasher, M.D., M.P.H., Chief Medical Officer, Hematology at BeiGene. “This milestone builds on the track record we’ve built with BRUKINSA to date, with approvals in more than 55 countries and regions, as we continue to fulfill our commitment to build a transformational global R&D model that enables broader, faster access to novel medicines.”

The EC approval follows a positive opinion granted in September by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based on results from the multicenter, global, single-arm, open-label, Phase 2 MAGNOLIA trial in patients with R/R MZL who received at least one anti-CD-20 based regimen. In the trial, BRUKINSA achieved a high overall response rate of 68% with 26% of patients achieving complete remission, as assessed by an Independent Review Committee (IRC). Responses were observed in all patients regardless of MZL subtypes. BRUKINSA also delivered rapid and durable disease control with a median time to response of 2.8 months.ⁱ

BRUKINSA was generally well-tolerated and safety in MZL was consistent with its established profile. The most common grade ≥3 adverse events (>5%) included neutropenia (23%), pneumonia (11%), thrombocytopenia (8%) and anemia (8%). There were low rates of discontinuation due to adverse events at 3.5%, highlighting that BRUKINSA continued to be well-tolerated.ⁱⁱ

“This milestone marks the first and only approved BTK inhibitor for marginal zone lymphoma in Europe,” comments Pier Luigi Zinzani, MD., PhD., Full Professor of Haematology at the Institute of Haematology “Seràgnoli”, University of Bologna, Italy. “As there is no current standard of care in Europe, the approval of BRUKINSA provides a chemotherapy-free treatment option for people with MZL that has shown meaningful efficacy with durable and high response rates across MZL subtypes.”

Gerwin Winter, Senior Vice President, Head of Europe at BeiGene, notes, “We are excited to bring the first and only BTKi approved for MZL to patients in Europe and look forward to continuing to work with our growing and dedicated teams to make our medicine accessible to patients who need them across Europe.”

BRUKINSA is also approved in the 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, and last month, CHMP issued a positive opinion recommending approval of BRUKINSA for the treatment of adult patients with chronic lymphocytic leukemia (CLL).

BeiGene has obtained reimbursement for BRUKINSA for the treatment of WM in Austria, Belgium, Denmark, England and Wales, Germany, Italy, Iceland, Ireland, The Netherlands, Spain, and Switzerland, while additional countries across Europe are currently going through the reimbursement process.

About Marginal Zone Lymphoma

MZL is a group of ultra-rare, slow growing B-cell malignancies that begin in the marginal zones of lymph tissue.ⁱⁱⁱ Epidemiological data from Europe is limited, but the incidence rate of MZL is estimated to range between 20 and 30 per million per year.^iv,v,vi 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.^vii

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. BRUKINSA was specifically designed to deliver targeted 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 4,500 subjects in 35 trials across 28 markets. To date, BRUKINSA has received approvals covering more 55 countries and regions, including the United States, China, the EU, Great Britain, Switzerland, Canada, Australia, and additional international markets.

BeiGene Oncology

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 3,300 colleagues dedicated to advancing more than 100 clinical trials that have involved more than 16,000 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 U.S., China, the European Union, Great Britain, Switzerland, 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, 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.
