China National Medical Products Administration Approves BeiGene’s Tislelizumab for Patients with Classical Hodgkin’s Lymphoma Who Have Received at Least Two Prior Therapies
-- Second BeiGene-discovered drug to receive regulatory approval, first in China -- Tislelizumab is an anti–PD-1 antibody specifically designed to minimize binding to FcγR on macrophages
BEIJING, China and CAMBRIDGE, Mass., Dec. 27, 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 its anti-PD-1 antibody tislelizumab has received approval from the China National Medical Products Administration (NMPA) as a treatment for patients with classical Hodgkin’s lymphoma (cHL) who have received at least two prior therapies. The new drug application (NDA) was previously granted priority review by the NMPA. Following the recent approval of BRUKINSA™ (zanubrutinib) by the U.S. Food and Drug Administration (FDA), tislelizumab is BeiGene’s first drug approved in China.
Developed by BeiGene scientists, tislelizumab is a humanized IgG4 anti-PD-1 monoclonal antibody specifically designed to minimize binding to FcγR, which is believed to play an essential role in activating phagocytosis in macrophages to minimize its negative impact on T effector cells.
“We’ve been working to develop improved therapies for cancer patients around the world. The discovery of immunotherapy revolutionized the cancer treatment paradigm and has since brought new treatment options and hope to people with cancer,” commented John V. Oyler, Chairman, Co-Founder, and CEO of BeiGene. “Tislelizumab is a differentiated anti-PD-1 antibody and has demonstrated encouraging clinical efficacy and safety in patients with relapsed/refractory cHL. We look forward to its further development in a broad array of solid tumors and hematological malignancies.”
Professor Jun Zhu, M.D., Ph.D., Director of the Lymphoma Department at Beijing Cancer Hospital commented, “Anti-PD-1 antibodies are becoming a new treatment option for lymphoma patients. With a complete response rate of more than 60%, BeiGene’s tislelizumab has demonstrated significant efficacy and a good safety profile as a monotherapy in patients with relapsed/refractory cHL. The approval of tislelizumab will bring a meaningful treatment option for those patients with cHL in China.”
“Currently, BeiGene is conducting 15 registration-enabling clinical trials to evaluate tislelizumab in 23 countries and regions globally in prevalent cancer types such as lung, liver, esophageal and gastric cancers, with over 4,800 patients enrolled to date in its broad development program. We are grateful to the dedicated clinicians and particularly the patients who participated in these clinical studies,” said Wendy Yan, Senior Vice President and Global Head of Regulatory Affairs at BeiGene.
In addition, a supplementary new drug application (sNDA) for tislelizumab in patients with previously treated locally advanced or metastatic urothelial carcinoma has been accepted and granted priority review by the Center for Drug Evaluation (CDE) at the NMPA.
Tislelizumab is a biologic product approved under the Marketing Authorization Holder (MAH) pilot program in China, and will be manufactured by Boehringer Ingelheim at its facility in Shanghai as the commercial supplier. Established in 1885, Boehringer Ingelheim has over 35 years of biotechnology experience, and with more than 3,600 employees and a global network its contract biopharmaceutical manufacturing business has helped to bring more than 30 molecules to the market globally.
The NMPA approval is based on the clinical results from a single-arm, multi-center, pivotal Phase 2 trial BGB-A317-203 (NCT03209973). Among the patients who were evaluable for responses, with a minimum follow-up of 12 months and a median follow-up of 14 months, the independent review committee (IRC)-assessed objective response rate (ORR) was 76.9% and the complete response (CR) rate was 61.5%.
In the R/R cHL trial BGB-A317-203, the most common adverse reactions (≥ 10%) reported were pyrexia, hypothyroidism, weight increase, pruritus, decreased white blood cell count, upper respiratory tract infection, increased alanine aminotransferase (ALT), rash, decreased neutrophil count, cough, fatigue, and increased blood bilirubin. Grade 3 and above adverse reactions occurring in ≥ 2% of patients included pneumonitis, weight increase, severe skin reactions and hypertension. There was no fatal adverse reaction case reported from BGB-A317-203.
Like other immune checkpoint inhibitors, tislelizumab could cause immune- related adverse events (irAE) that mainly include pneumonitis, diarrhea and colitis, hepatitis, endocrinopathies (hypothyroidism, hyperthyroidism and other thyroid disorders, adrenocortical insufficiency, hyperglycemia and type 1 diabetes mellitus) and skin adverse reactions. Occasionally, nephritis, pancreatitis, myocarditis and other irAE were also reported.
The recommended dose of tislelizumab is 200 mg administered as an intravenous infusion every three weeks, until disease progression or intolerable toxicity.
BeiGene is currently working with Boehringer Ingelheim to prepare for the commercial supply to launch of tislelizumab in China.
About Classical Hodgkin’s Lymphoma
Hodgkin’s lymphoma is a group of malignancies that affects the lymph nodes and the tissues of the lymphatic system. The most common form is classical Hodgkin’s lymphoma (cHL), which accounts for 95% of all Hodgkin’s lymphoma incidences1. It is most commonly diagnosed in young adults between the ages of 15 and 35 and in older adults over age 552. Enlarged lymph nodes are typically the initial symptom, but cancer cells can be detected in liver, spleen, and bone marrow in late stage disease. Although first-line chemo-radiotherapy has demonstrated significant improvement in the survival of patients with cHL, patients with primary refractory disease (approximately 5-10%) or those who relapse after responding to initial treatment (approximately 10-30%), usually have poor prognosis and traditional treatments have shown limited efficacy, representing an unmet medical need.
Tislelizumab (BGB-A317) is a humanized IgG4 anti–PD-1 monoclonal antibody specifically designed to minimize binding to FcγR on macrophages. In pre-clinical studies, binding to FcγR on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells. Tislelizumab is the first drug from BeiGene’s immuno-oncology biologics program and is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers.
Tislelizumab is approved by the China National Medical Products Administration (NMPA) as a treatment for patients with classical Hodgkin’s lymphoma who received at least two prior therapies. A supplemental new drug application (sNDA) for tislelizumab in patients with previously treated locally advanced or metastatic urothelial carcinoma has been granted priority review by the Center for Drug Evaluation at the NMPA and is currently under review.
Tislelizumab will be manufactured by Boehringer Ingelheim at its facility in Shanghai as the commercial supplier. Following required qualifications and approvals, BeiGene plans to provide additional commercial supply through its commercial-scale biologics manufacturing facility in Guangzhou, which completed its initial phase of construction in September this year.
Tislelizumab is being studied in a broad clinical program as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers. Currently, 15 registration-enabling clinical trials are being conducted in China and globally, including 11 Phase 3 trials and four pivotal Phase 2 trials.
Tislelizumab is not approved for use outside China.
