Nanjing Leads Biolabs Co., Ltd. announced that LBL-024, an anti-PD-L1/4-1BB bispecific antibody independently developed by the company with global intellectual property rights for the treatment of neuroendocrine cancer, has obtained Orphan Drug Designation (ODD) from the U.S. Food and Drug Administration (FDA). This marks another significant milestone following the Breakthrough Therapy Designation granted to LBL-024 by the Center for Drug Evaluation (CDE) of National Medical Products Administration (NMPA) in China.

Dr. Charles Cai, Chief Medical Officer of Leads Biolabs, said "LBL-024 obtained Breakthrough Therapy Designation from CDE in October this year for the treatment of advanced extrapulmonary neuroendocrine cancer. Our clinical data to date has been very encouraging, suggesting that LBL-024 could meaningfully improve outcomes of patients living with this devastating disease. The grant of ODD from FDA further underscores the exceptional potential of LBL-024 to address a critical gap in this therapeutic area. These policy supports for obtaining Orphan Drug qualification will greatly expedite the commercialization of LBL-024, potentially changing the treatment landscape for patients with advanced neuroendocrine cancer who currently have few therapeutic options."

Dr. Xiaoqiang Kang, founder, chairman and CEO of Leads Biolabs, said "The receipt of ODD for LBL-024 from FDA represents a pivotal milestone in our global strategy. This designation not only enables LBL-024 to receive additional policy support and resource allocation during its development, accelerating its path to market and positioning it as a potential first-in-class therapeutic antibody targeting 4-1BB worldwide, but also provides us with greater market opportunities and avenues for growth on a global scale.

LBL-024 is a tetravalent bispecific antibody that simultaneously targets PD-L1 and 4-1BB, serving dual functions: blocking the immunosuppressive PD-1/PD-L1 pathway, and selectively co-stimulating 4-1BB in the tumor microenvironment to enhance immune responses. The dual functions of LBL-024—lifting PD-1/PD-L1 immune inhibition and intensifying 4-1BB modulated T cell activation—synergistically enhance the anti-tumor immune response.

LBL-024 received IND approvals from both FDA and NMPA on July 30, 2021 and September 9, 2021 respectively to conduct phase Ⅰ/Ⅱ clinical research, and has achieved outstanding results. Sponsored by Leads Biolabs, led by Professor Shen Lin from Beijing Cancer Hospital with participation of multiple clinical trial centers, the current clinical data demonstrate that LBL-024 monotherapy has more than doubled both the Objective Response Rate (ORR) and Overall Survival (OS) compared to existing treatments for this disease. Based on the current treatment status and the available safety and efficacy data, LBL-024 has entered into a single-arm pivotal trial for extrapulmonary neuroendocrine carcinomas in July 2024 and stands as the globally first 4-1BB-targetd drug candidates to have reached pivotal stage, according to Frost & Sullivan.
