FDA Fast Track Designation reflects the potential of BGB-B2033 in an area of high unmet need

SAN CARLOS, Calif.–(BUSINESS WIRE)–$ONC #BeOne–BeOne Medicines Ltd. (Nasdaq: ONC; HKEX: 06160; SSE: 688235), a global oncology company, today announced that the U.S. Food and Drug Administration (FDA) has granted the Company Fast Track Designation for BGB-B2033, its GPC3x4-1BB bispecific antibody for the treatment of adult patients with hepatocellular carcinoma (HCC) with disease progression on or after prior systemic treatment.

“The FDA awards Fast Track Designation to therapies that show potential to address an unmet medical need in serious or life-threatening conditions. The FDA’s decision reflects the encouraging profile of BGB-B2033 in advanced hepatocellular carcinoma, where patients continue to face limited treatment options,” said Julie Lepin, Senior Vice President and Chief Regulatory Affairs Officer at BeOne.

BeOne is currently conducting a global, multi-center Phase 1 clinical trial (NCT06427941) to explore the safety and anti-tumor activity of BGB-B2033, both alone and in combination with PD-1 inhibitor TEVIMBRA^® (tislelizumab).

About Hepatocellular Carcinoma

Hepatocellular Carcinoma (HCC) is the sixth most common cancer worldwide and the fourth leading cause of cancer-related death.¹ HCC accounts for 80% of all primary liver cancers, with the number of new cases expected to double between 2022 and 2050.² The rising burden of HCC is primarily attributed to the high prevalence of the hepatitis B and hepatitis C viruses (HBV/HBC) and lifestyle factors such as obesity, tobacco, and alcohol consumption.³ With approximately 80% of patients diagnosed in advanced stages and five-year survival rates for this patient population lower than 20%, new treatment options are needed beyond currently available systemic therapy.⁴

About BGB-B2033

BGB-B2033 is a bispecific antibody targeting GPC3 (glypican 3), a tumor-specific antigen highly expressed in HCC⁵, and 4-1BB, a co-stimulatory receptor associated with T-cell activation and tumor reactivity in HCC.⁶ The molecule has been designed with reduced antibody-dependent cellular cytotoxicity (ADCC) to prevent systemic toxicity.
