NANJING, China, Oct. 9, 2024 /PRNewswire/ — Nanjing Leads Biolabs Co., Ltd. (“Leads Biolabs”) announced that Center for Drug Evaluation (CDE) of National Medical Products Administration (NMPA) has granted Breakthrough Therapy Designation to LBL-024, an anti-PD-L1/4-1BB bispecific antibody independently developed by Leads Biolabs with global intellectual property rights, for the treatment of the patients with advanced extrapulmonary neuroendocrine carcinoma (EP-NEC) who have progressed after receiving two or more lines of chemotherapy. The Breakthrough Therapy Designation awarded to LBL-024 stems from its remarkable clinical efficacy and safety profile in patients with advanced EP-NEC who failed in second-line and above chemotherapy. 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.

Breakthrough Therapy refers to innovative or improved drugs that treat life-threatening conditions or significantly impact quality of life, where no effective treatment exist, or there is sufficient evidence that the therapy offers clear advantages over existing treatment options. In July 2012, the U.S. Food and Drug Administration (FDA) pioneered the “Breakthrough Therapy” review process, complementing fast track, accelerated approval, and priority review mechanisms. By accelerating the approval process and fostering closer collaboration, Breakthrough Therapy Designation facilitates faster development and market access for drugs with significant clinical potential. Historically, FDA data suggests that Breakthrough Therapy Designation can reduce time-to-market by approximately 2.5 years on average.
