On July 1, 2020 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, reported that the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has accepted a supplemental new drug application (sNDA) of BeiGene’s anti-PD-1 antibody tislelizumab for the treatment of patients with previously treated unresectable hepatocellular carcinoma (HCC), the most common form of liver cancer (Press release, BeiGene, JUL 1, 2020, View Source [SID1234561654]).

"We are excited by the acceptance of our first filing for tislelizumab in liver cancer," commented Xiaobin Wu, Ph.D., General Manager of China and President of BeiGene. "Half of the world’s liver cancer patients reside in China, and there is a significantly unmet medical need. We will continue our communications with the CDE and hope to bring these patients a viable treatment option in the near future."

The sNDA is supported by clinical results from a pivotal Phase 2 trial of tislelizumab in patients with previously treated unresectable HCC (NCT03419897). The study enrolled 249 patients with unresectable HCC from eight countries and regions in Asia and Europe, including 138 patients who received one line of prior systemic therapy and 111 patients who received at least two lines of prior therapies. Patients received tislelizumab monotherapy (200 mg every three weeks) and the primary endpoint of the trial was objective response rate as assessed by independent review committee (IRC). Results of this study will be presented at an upcoming medical conference.

About Hepatocellular Carcinoma

HCC is a major global health problem, accounting for 85-90 percent of all reported cases of liver cancer.1 Liver cancer is the sixth most common type of cancer, with an estimated 841,080 new cases in 2018 worldwide;2 it was also the fourth most common cause of cancer-related mortality, responsible for an estimated 781,631 deaths in 2018.3 China accounts for approximately 50 percent of both new HCC cases and HCC-related deaths worldwide in 2018. 4

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 internationally 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.

In addition, three supplemental new drug applications (sNDAs) for tislelizumab have been accepted by the Center for Drug Evaluation (CDE) of the NMPA and are under review, for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) in combination with chemotherapy, for first-line treatment of patients with advanced non-squamous NSCLC in combination with chemotherapy, and for previously treated unresectable hepatocellular carcinoma.

Currently, 16 potentially registration-enabling clinical trials are being conducted in China and globally, including 12 Phase 3 trials and four pivotal Phase 2 trials.

Tislelizumab is not approved for use outside of China.
