By Fineline Cube Shenzhen Hybio Pharmaceutical Co., Ltd. (SHE: 300199) announced today that the U.S. Food and Drug Administration (FDA) has accepted for review its Abbreviated New Drug Application (ANDA) for generic tirzepatide injection, positioning the company as a potential first-to-file challenger to Eli Lilly’s blockbuster dual GLP-1R/GIPR agonist franchise.
The ANDA encompasses six dosage strengths in single-dose prefilled pens with proposed indications for type 2 diabetes (T2D), chronic weight management, and obstructive sleep apnea (OSA). Notably, Hybio submitted two first-to-file ANDAs in May 2026 for T2D and weight management indications, accompanied by Paragraph IV certifications challenging Eli Lilly’s relevant patents—a strategic move that could secure 180-day market exclusivity if successful.
