CAMBRIDGE, Mass. & BEIJING--(BUSINESS WIRE)--
BeiGene (NASDAQ: BGNE; HKEX: 06160), 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 BRUKINSA® (zanubrutinib) has been approved in Australia for the treatment of adult patients with Waldenström’s macroglobulinemia (WM) who have received at least one prior therapy or in first line treatment for patients unsuitable for chemo-immunotherapy.1 Following registration of BRUKINSA with the Australia Therapeutic Goods Administration (TGA), these patients will have immediate access to BRUKINSA through a BeiGene sponsored post-approval, pre-reimbursement access program.

In addition, BRUKINSA recently received approval from the Singapore Health Sciences Authority (HSA) for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.
“BTK inhibition is an established mode of treatment for patients with WM, and the ASPEN trial showed that BRUKINSA is highly effective and has improved tolerability compared to the first-generation BTK inhibitor,” said Professor Con Tam, MBBS, M.D., Disease Group Lead for Low Grade Lymphoma and Chronic Lymphocytic Leukemia at the Peter MacCallum Cancer Centre and a principal investigator on the BRUKINSA clinical program. “BeiGene first began clinical trials of BRUKINSA in Australia in 2013, and since that time, many Australians have benefitted from treatment as part of ongoing clinical studies. We hope this therapy will offer new hope for people living with WM in Australia.”
In Australia, more than 6,000 people are diagnosed with non-Hodgkin’s lymphoma (NHL) each year, making it the sixth most common cancer in adults.2 WM is a rare, slow-growing lymphoma that occurs in less than two percent of patients with NHL.3 The disease usually affects older adults and is primarily found in the bone marrow, although it may also impact lymph nodes and the spleen.3
“While WM is a slow-growing lymphoma, not all patients fully respond to existing therapies and many discontinue treatment due to side effects,” commented David Young, the National Team Leader at the WMozzies. “We are pleased to hear that people living with WM in Australia will have immediate access to this next-generation BTK inhibitor that has demonstrated clinical benefit with potential to improve treatment outcomes.”
BeiGene has submitted for reimbursement of WM to the Australia Pharmaceutical Benefits Advisory Committee (PBAC). In a first for the PBAC, BeiGene expects to enter a facilitated resolution pathway in order to seek a listing date for the WM indication.
“BRUKINSA has been shown to induce deep and durable responses with reduced off-target side effects, suggesting improved clinical benefit compared to standard BTK inhibitor therapy,” said Jane Huang, M.D., Chief Medical Officer, Hematology at BeiGene. “We are grateful to the Australian investigators, patients and families who participated in clinical trials contributing to TGA approval. Our ability to offer BRUKINSA to people in Australia impacted by WM is another step toward fulfilling our goal of increasing affordable access to oncology medicines around the world.”
“This approval in Australia, and our recent approval in Singapore, represent BRUKINSA’s continued expansion in the APAC region,” added Adam Roach, Vice President and Head of Commercial for APAC (ex-Greater China) at BeiGene. “We have been building commercial teams in these markets to support our goal of bringing this potential best-in-class BTK inhibitor to patients who need them globally.”
The Australian registration for BRUKINSA in WM is based on efficacy results from the ASPEN clinical trial, a Phase 3 randomized, open-label, multicenter trial (NCT03053440) that evaluated BRUKINSA compared to ibrutinib in patients with relapsed or refractory (R/R) or treatment-naïve (TN) WM who harbor a MYD88 mutation (MYD88MUT). In the ASPEN trial, BRUKINSA demonstrated a numerically higher very good partial response (VGPR) rate (28.4%, 95% CI: 20, 38) compared to ibrutinib (19.2%, 95% CI: 12, 28), although the primary endpoint of statistical superiority related to deep response (VGPR or better) was not met.
In the ASPEN trial, of the 101 patients with WM randomized and treated with BRUKINSA, 5% of patients discontinued due to adverse events, including cardiomegaly, neutropenia, plasma cell myeloma, and subdural hemorrhage. Adverse events leading to dose reduction occurred in 14.9% of patients, with the most common being neutropenia (3.0%) and diarrhea (2.0%).
The overall safety profile of BRUKINSA is based on pooled data from 779 patients with B-cell malignancies treated with BRUKINSA in clinical trials. The most common adverse reactions (≥20%) with BRUKINSA were neutropenia, thrombocytopenia, upper respiratory tract infection, hemorrhage/hematoma, rash, bruising, anemia, musculoskeletal pain, diarrhea, pneumonia, and cough. The most common Grade 3 or higher adverse reactions (≥5%) were neutropenia, thrombocytopenia, pneumonia, and anemia.
The recommended dose of BRUKINSA is either 160 mg twice daily or 320 mg once daily, taken orally with or without food. The dose may be adjusted for adverse reactions and reduced for patients with severe hepatic impairment and certain drug interactions.
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 approved in the following indications and regions:
For the treatment of mantle cell lymphoma (MCL) in adult patients who have received at least one prior therapy (United States, November 2019)*;
For the treatment of MCL in adult patients who have received at least one prior therapy (China, June 2020)**;
For the treatment of chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) in adult patients who have received at least one prior therapy (China, June 2020)**;

IMPORTANT U.S. SAFETY INFORMATION FOR BRUKINSA (ZANUBRUTINIB)
Warnings and Precautions
Hemorrhage
Fatal and serious hemorrhagic events have occurred in patients with hematological malignancies treated with BRUKINSA monotherapy. Grade 3 or higher hemorrhage including intracranial and gastrointestinal hemorrhage, hematuria and hemothorax have been reported in 3.4% of patients treated with BRUKINSA monotherapy. Hemorrhage events of any grade occurred in 35% of patients treated with BRUKINSA monotherapy.
Bleeding events have occurred in patients with and without concomitant antiplatelet or anticoagulation therapy. Co-administration of BRUKINSA with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage.
Monitor for signs and symptoms of bleeding. Discontinue BRUKINSA if intracranial hemorrhage of any grade occurs. Consider the benefit-risk of withholding BRUKINSA for 3-7 days pre- and post-surgery depending upon the type of surgery and the risk of bleeding.
Infections
Fatal and serious infections (including bacterial, viral, or fungal) and opportunistic infections have occurred in patients with hematological malignancies treated with BRUKINSA monotherapy. Grade 3 or higher infections occurred in 27% of patients, most commonly pneumonia. Infections due to hepatitis B virus (HBV) reactivation have occurred.
Consider prophylaxis for herpes simplex virus, pneumocystis jiroveci pneumonia and other infections according to standard of care in patients who are at increased risk for infections. Monitor and evaluate patients for fever or other signs and symptoms of infection and treat appropriately.
Cytopenias
Grade 3 or 4 cytopenias, including neutropenia (26%), thrombocytopenia (11%) and anemia (8%) based on laboratory measurements, developed in patients treated with BRUKINSA monotherapy. Grade 4 neutropenia occurred in 13% of patients, and Grade 4 thrombocytopenia occurred in 3.6% of patients.
Monitor complete blood counts regularly during treatment and interrupt treatment, reduce the dose, or discontinue treatment as warranted. Treat using growth factor or transfusions, as needed.
Second Primary Malignancies
Second primary malignancies, including non-skin carcinoma, have occurred in 14% of patients treated with BRUKINSA monotherapy. The most frequent second primary malignancy was non-melanoma skin cancer, reported in 8% of patients. Other second primary malignancies included malignant solid tumors (4.0%), melanoma (1.7%) and hematologic malignancies (1.2%). Advise patients to use sun protection and monitor patients for the development of second primary malignancies.
Cardiac Arrhythmias
Atrial fibrillation and atrial flutter were reported in 3.2% of patients treated with BRUKINSA monotherapy. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk. Grade 3 or higher events were reported in 1.1% of patients treated with BRUKINSA monotherapy. Monitor signs and symptoms for atrial fibrillation and atrial flutter and manage as appropriate.
Embryo-Fetal Toxicity
Based on findings in animals, BRUKINSA can cause fetal harm when administered to a pregnant woman. Administration of zanubrutinib to pregnant rats during the period of organogenesis caused embryo-fetal toxicity including malformations at exposures that were 5 times higher than those reported in patients at the recommended dose of 160 mg twice daily. Advise women to avoid becoming pregnant while taking BRUKINSA and for 1 week after the last dose. Advise men to avoid fathering a child during treatment and for 1 week after the last dose.
If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.
Adverse reactions
The most common adverse reactions, including laboratory abnormalities, in ≥ 30% of patients who received BRUKINSA (N = 847) included decreased neutrophil count (54%), upper respiratory tract infection (47%), decreased platelet count (41%), hemorrhage (35%), decreased lymphocyte count (31%), rash (31%) and musculoskeletal pain (30%).
Drug Interactions
CYP3A Inhibitors: When BRUKINSA is co-administered with a strong CYP3A inhibitor, reduce BRUKINSA dose to 80 mg once daily. For coadministration with a moderate CYP3A inhibitor, reduce BRUKINSA dose to 80 mg twice daily.
CYP3A Inducers: Avoid coadministration with moderate or strong CYP3A inducers.
Specific Populations
Hepatic Impairment: The recommended dose of BRUKINSA for patients with severe hepatic impairment is 80 mg orally twice daily.
