Second approval of tislelizumab in China, first in solid tumor

BEIJING, China and CAMBRIDGE, Mass., April 10, 2020 (GLOBE NEWSWIRE) --BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biotechnology 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 locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. Following tislelizumab’s initial approval in classical Hodgkin’s lymphoma (cHL) by the NMPA in December 2019, this is the second indication approved for tislelizumab, and the first in a solid tumor indication. The supplemental new drug application (sNDA) was previously granted priority review by the Center for Drug Evaluation (CDE) of the NMPA.
“At BeiGene, we strive to bring innovative, impactful, and quality treatments to patients around the globe. This is our third NDA approval in the past five months for our internally developed products, a tremendous accomplishment for a young biotechnology company like BeiGene and validation of the team’s hard work,” commented John V. Oyler, Chairman, Co-Founder, and CEO of BeiGene. “Our strategy for tislelizumab has always been to pursue a broad label and serve patients who are battling different types of cancer. With tislelizumab’s first solid tumor approval, we are even more excited about the outlook for this immunotherapy than ever.”
“Patients with advanced UC have limited treatment options, so we are delighted to have tislelizumab, a new immuno-oncology treatment available to them. Supported by encouraging efficacy and safety results from the trial, including an objective response rate of 24.8%, we believe tislelizumab will bring significant benefits to this patient population,” commented Dingwei Ye, M.D., Ph.D., Professor and Vice President of the Fudan University Shanghai Cancer Center.
“We are thrilled about today’s approval of tislelizumab in UC, which was made possible by dedicated clinicians who participated in the trial, patients who entrusted our clinical trial with their treatment, and the team at BeiGene. We hope our broad development program for tislelizumab, which encompasses 15 potentially registration-enabling trials globally and in China, in indications including lung, liver, esophageal, gastric, nasopharyngeal, and MSI-H or dMMR cancers, in addition to classical Hodgkin’s lymphoma and UC, will continue its momentum and benefit more patients,” said Wendy Yan, Senior Vice President and Global Head of Regulatory Affairs at BeiGene.
The NMPA approval is based on the clinical results from a single-arm, multi-center pivotal Phase 2 trial of tislelizumab in patients in China and South Korea with PD-L1+ locally advanced

or metastatic UC who were previously treated with platinum-containing chemotherapy (NCT04004221). Among patients who were evaluable for response, with a minimum follow-up of 12 months and a median follow-up of 14 months, the objective response rate (ORR) as assessed by the independent review committee (IRC) per RECIST v1.1 criteria was 24.8%, and the complete response (CR) rate was 9.9%.
The safety data for tislelizumab included in the label is based on 934 patients treated with tislelizumab monotherapy from four clinical trials, including the aforementioned pivotal Phase 2 trial in patients with UC. Most common (≥ 10%) adverse reactions included rash, fatigue, and increased alanine aminotransferase. Grade 3 or higher adverse reactions occurring in ≥ 1% of patients included: increased gamma‑glutamyl transferase, anemia, increased aspartate aminotransferase, increased alanine aminotransferase, pneumonitis, severe skin reactions, and hypokalemia.
Like other immune checkpoint inhibitors, tislelizumab could cause immune-related adverse reactions that mainly include pneumonitis, diarrhea and colitis, hepatitis, endocrinopathies (hypothyroidism, hyperthyroidism and thyroiditis, adrenocortical insufficiency, hyperglycemia and type 1 diabetes mellitus), and skin adverse reactions. Occasionally, nephritis, pancreatitis, myocarditis, myositis, and other immune-related adverse reactions 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.
Tislelizumab is a biologic product approved under the Marketing Authorization Holder (MAH) pilot program in China and is being manufactured by Boehringer Ingelheim at its facility in Shanghai as the commercial supplier. Established in 1885, Boehringer Ingelheim has over 35 years of biologic manufacturing 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.
About Urothelial Carcinoma
Urothelial carcinoma (UC), also known as transitional cell carcinoma (TCC), is by far the most common type of bladder cancer1, accounting for more than 90 percent of all bladder cancers2. Bladder cancer is the 10th most common cancer worldwide with approximately 550,000 new cases in 20183. In China, bladder cancer is the 8th most common cancer in men with approximately 62,000 new cases in 20194. Although UC is most common in the bladder, it can occur in other parts of the urinary system.
About Tislelizumab
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 and for patients with locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.
Tislelizumab is being 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 2019.
Currently, 15 registration-enabling clinical trials of tislelizumab 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.
