Zoliflodacin: First Approval.

Zoliflodacin (NUZOLVENCE®), a first-in-class, single-dose, oral spiropyrimidinetrione bacterial type II topoisomerase inhibitor, has been developed by Innoviva Specialty Therapeutics in collaboration with the Global Antibiotic Research and Development Partnership (GARDP) and the U.S. National Institute of Allergy and Infectious Diseases (NIAID) for the treatment of uncomplicated urogenital gonorrhea (uUGC). In December 2025, zoliflodacin was approved by the US FDA for the treatment of uUGC due to Neisseria gonorrhoeae in adults and pediatric patients 12 years of age and older weighing at least 35 kg. This article summarizes the milestones in the development of zoliflodacin leading to this first approval for the treatment of uUGC.
