Wockhardt Advances India's Antibiotic Frontier: MAA Filed for Game Changing WCK 5222 with EMA

Wockhardt Ltd. has submitted a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) for WCK 5222 (Zidebactam 1g + Cefepime 2g), a novel antibiotic targeting multi-drug resistant Gram-negative infections. This marks the first Indian-discovered New Chemical Entity (NCE) for pan-European approval, building on EMA's prior Accelerated Assessment grant. Approval could transform treatments for serious infections like cUTI and HAP/VAP.

WCK 5222, branded Zaynich®, combines zidebactam a β-lactam enhancer with cefepime to combat MDR and XDR Gram-negative pathogens, overcoming resistance via a novel mechanism. Developed fully in India, it addresses critical global antimicrobial resistance gaps. Phase 3 ENHANCE-1 trial showed 96.8% clinical efficacy in 530 cUTI patients across global sites.
