CAMBRIDGE, Mass. & BEIJING

BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biotechnology company focused on developing and commercializing innovative medicines worldwide, today announced that the first patient has been dosed in a Phase 1 clinical trial of BGB-15025, its investigational hematopoietic progenitor kinase 1 (HPK1) inhibitor. BGB-15025 is designed to be a potent and highly selective small molecule oral inhibitor of HPK1, a kinase downstream of the T cell receptor (TCR) signaling pathway that is believed to play a key role in T cell activation.

“We are incredibly proud of BeiGene’s research organization, which now has over 450 people, and its ability to discover not only potentially best-in-class cancer treatments but also investigational agents like BGB-15025, which we believe to be among the first HPK1 inhibitors to enter the clinic and represent a novel immuno-oncology approach targeting T cell activation to fight cancer growth,” commented Lai Wang, Ph.D., Senior Vice President, Head of Global Research, Clinical Operations & Biometrics and APAC Clinical Development at BeiGene. “We believe that the unique nature of BGB-15025 and the HPK1 pathway provides us with a compelling scientific rationale for investigating it as a monotherapy and in combination with our anti-PD-1 antibody, tislelizumab. We are excited to advance its clinical development globally.”

This first-in-human Phase 1 trial (NCT04649385) will assess the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of BGB-15025 alone and in combination with tislelizumab in patients with advanced solid tumors. This trial will be conducted in multiple countries globally.

About BGB-15025

BGB-15025 is an investigational hematopoietic progenitor kinase 1 (HPK1) inhibitor discovered and being developed by BeiGene. HPK1 is a key negative feedback regulator of T-cell receptor signaling, which is believed to play a key role in antitumor immune response. In preclinical studies, the inhibition of HPK1 enhanced T-cell activation, which is expected to enhance the anti-tumor activity of anti-PD-1 inhibitors such as BeiGene’s tislelizumab.

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 approved medicine from BeiGene’s immuno-oncology biologics program and is being developed globally 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 in China for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC) in combination with chemotherapy. Tislelizumab has also received conditional approval in China for the treatment of patients with classical Hodgkin’s lymphoma (cHL) who received at least two prior therapies, and for the treatment of 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. Full approval for these indications is contingent upon results from ongoing randomized, controlled confirmatory clinical trials.

In addition, three supplemental Biologics License Applications for tislelizumab have been accepted and are under review in China for first-line treatment of patients with advanced non-squamous NSCLC in combination with chemotherapy, for the second- or third-line treatment of patients with locally advanced or metastatic NSCLC who progressed on prior platinum-based chemotherapy, and for previously treated unresectable hepatocellular carcinoma.

Currently, 15 potentially registration-enabling clinical trials are being conducted in China and globally, including 12 Phase 3 trials and two pivotal Phase 2 trials.

In January 2021, BeiGene and Novartis entered into a collaboration and license agreement to develop, manufacture, and commercialize tislelizumab in North America, Europe, and Japan.

Tislelizumab is not approved for use outside of China.
