BRUKINSA was granted its first breakthrough therapy designation in China with this application
The application is supported by SEQUOIA trial results, which demonstrated BRUKINSA’s superiority in efficacy over chemoimmunotherapy
BRUKINSA received the China NMPA conditional approval for the treatment of patients with relapsed or refractory chronic lymphocytic leukemia in June 2020
CAMBRIDGE, Mass. & BEIJING--(BUSINESS WIRE)--$BGNE #BGNE--BeiGene (NASDAQ: BGNE; HKEX: 06160; SSE: 688235), a global, science-driven biotechnology company focused on developing innovative and affordable medicines, today announced that the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has accepted a supplemental new drug application (sNDA) for BeiGene’s BTK inhibitor BRUKINSA (zanubrutinib) as a treatment for adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) and granted BRUKINSA breakthrough therapy designation (BTD).
“This is BRUKINSA’s first filing in treatment-naïve CLL supported by the positive global Phase 3 SEQUOIA trial, a remarkable step forward in its global registration program. As presented at ASH, BRUKINSA significantly prolonged progression-free survival and was generally well-tolerated in these patients, with demonstrated superiority over chemoimmunotherapy in the SEQUOIA trial,” commented Jane Huang, M.D., Chief Medical Officer of Hematology at BeiGene. “Together with the filing in Waldenström’s macroglobulinemia, we are hoping to expand the clinical use of this potential best-in-class BTK inhibitor from relapsed or refractory setting to frontline care for the blood cancer community in China.”
The sNDA is supported by clinical results from the randomized, multicenter, global Phase 3 SEQUOIA trial (NCT03336333) comparing BRUKINSA to bendamustine in combination with rituximab (B+R) in patients with treatment-naïve CLL.
As assessed by an independent review committee (IRC), BRUKINSA demonstrated superiority in progression-free survival (PFS) over B+R. With a median follow-up of 26.15 months, the 24-month PFS was 85.5% (95% CI: 80.1, 89.6) with BRUKINSA, compared to 69.5% (95% CI: 62.4, 75.5) with B+R, and the hazard ratio (HR) was 0.42 (95% CI: 0.27, 0.63), p<0.0001. BRUKINSA was generally well tolerated with a safety profile consistent with its broad clinical program, including a low rate of atrial fibrillation.
About Chronic Lymphocytic Leukemia
Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in adults, with a global incidence of approximately 114,000 new cases in 2017. CLL affects white blood cells or lymphocytes in the bone marrow, 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.1,2,3 The BTK pathway is a known route that signals malignant B cells and contributes to the onset of CLL.4 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.5
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 has received 20 approvals covering 43 countries 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)**;

IMPORTANT U.S. SAFETY INFORMATION FOR BRUKINSA (ZANUBRUTINIB)
Warnings and Precautions
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.
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.
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.
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.
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.
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%).
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.
Hepatic Impairment: The recommended dose of BRUKINSA for patients with severe hepatic impairment is 80 mg orally twice daily.
