The U.S. Food and Drug Administration (FDA) has approved Akeso Inc.’s differentiated PD-1 monoclonal antibody, penpulimab-kcqx, in combination with cisplatin or carboplatin and gemcitabine for the first-line treatment of adult recurrent or metastatic non-keratinizing nasopharyngeal carcinoma (NPC). The FDA also approved penpulimab-kcqx as a single agent for adults with metastatic non-keratinizing NPC with disease progression on or after platinum-based chemotherapy and with least one other prior line of therapy.

Penpulimab-kcqx was developed independently by Akeso, with further development and commercialization managed through a joint venture with Chia Tai-Tianqing Pharmaceutical Group.

This milestone marks penpulimab-kcqx as Akeso’s first internally developed innovative biologic to receive FDA approval. The approval underscores the robust clinical research behind penpulimab-kcqx and marks Akeso’s successful entry into the United States regulatory system for the first time.

The FDA approval is based on the international Phase III clinical trial AK105-304 and the pivotal AK105-202 study, which supported the two Biologics License Application (BLA) for penpulimab-kcqx. These studies demonstrated the drug’s clinical benefits and favorable safety profile across two stages of treatment for metastatic NPC. AK105-304 is a randomized, double-blind, international Phase III trial that enrolled NPC patients of diverse ethnicities. The data will be presented at the 2025 American Association for Cancer Research (AACR) Annual Meeting. Previously, the FDA granted penpulimab-kcqx Breakthrough Therapy Designation (BTD), Orphan Drug Designation (ODD), and Fast Track Designation (FTD) for NPC treatment, highlighting the critical unmet need for this therapy.

Dr. Yu Xia, Founder, Chairwoman, President & CEO of Akeso, expressed: “We are very excited by the approval of penpulimab-kcqx’s approval in the US FDA for first line and later line NPC.  Beyond reaching our first international regulatory milestone, this approval also provides an important immunotherapy treatment option for patients with NPC in the United States. The FDA approval of penpulimab-kcqx not only highlights the quality of our innovation but also underscores Akeso’s focus on delivering treatments for difficult to treat cancers for patients around the world.”
