Akeso Announces FDA Approval for Penpulimab-kcqx in Two BLA Indications for Comprehensive Treatment of Advanced Nasopharyngeal Carcinoma

HONG KONG, April 24, 2025 /PRNewswire/ -- Akeso, Inc. (9926.HK) ("Akeso" or the "Company") is excited to announce that the U.S. Food and Drug Administration (FDA) has approved its 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). 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. This achievement highlights the company's innovative drug development capabilities and its commitment to adhering to the highest international standards in pharmaceutical quality management.

The FDA's approval of penpulimab-kcqx validates Akeso's international drug development strategy and expansion capabilities. This approval lays a strong foundation for Akeso's continued clinical development efforts in the global therapeutics markets.

Penpulimab-kcqx has been approved in China for two indications: 1. first-line treatment of advanced NPC, and 2. second or later line treatment of advanced NPC. The recent FDA approval of penpulimab-kcqx offers a new, immunotherapy option for advanced NPC patients in the US.

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.

According to the WHO 2020 Global Cancer Statistics, over 133,000 new NPC cases are diagnosed annually worldwide, with more than 70% of the patients presented with locally advanced disease. Recurrent or metastatic NPC has a poor prognosis and limited survival. Penpulimab-kcqx's FDA approval will expand the number of NPC patients that can benefit from its treatment.

Prof. Chaosu Hu, Principal Investigator of penpulimab-kcqx from Fudan University Shanghai Cancer Center, commented: "This milestone enhances international treatment guidelines for advanced NPC and extends the benefits of China's innovations to global patients, ultimately reshaping the treatment landscape for metastatic NPC worldwide."

Prof. Xiaozhong Chen, Investigator of penpulimab-kcqx from Zhejiang Cancer Hospital, added: "The FDA approval of penpulimab-kcqx confirms its high efficacy and low toxicity, positioning China's innovative drug development in alignment with international standards."

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. We are deeply grateful to all the researchers, participants, and patients who have contributed to this success. Akeso will continue to advance first and best in class therapies, including bispecific antibodies and CD47 inhibitors, challenge global standards of care and unlocking the full potential of our pipeline for cancer patients everywhere."
