US FDA Approves Jecho Bio’s Independently Developed Long-Acting IL-15 (JL19001) Injection for Clinical Trials for Non-Muscle-Invasive Bladder Cancer

Nov 14, 2025, Jecho (Tianjin) Biopharmaceutical Co., Ltd. (“Jecho Bio”), a global, clinical stage biopharmaceutical company advancing medicines focusing in oncology, announced a major regulatory milestone.  Jecho’s independently developed innovative drug, JL19001, an IL-15/human serum albumin fusion protein, has been approved by the U.S. Food and Drug Administration (FDA) to begin clinical trials for non–muscle-invasive bladder cancer.

This achievement further advances the international clinical development for JL19001, as it was approved to begin clinical trials by China’s National Medical Products Administration (NMPA) in September 2025.

Notably, this approval is the tenth IND clearance and second U.S. FDA IND clearance Jecho Bio has obtained, validating Jecho Bio’s strong capabilities in innovative drug development.


About JL19001 Injection

JL19001 is a recombinant fusion protein composed of human serum albumin (HSA) and IL-15Rα/IL-15. It activates NK cells and CD8+ T cells, enhancing both innate and adaptive immune responses. When used in combination with Bacillus Calmette–Guérin (BCG) therapy for patients with non–muscle-invasive bladder cancer (NMIBC), it may help patients avoid radical cystectomy and improve both survival rates and quality of life.
