Innoviva Specialty Therapeutics, a subsidiary of Innoviva, Inc. (NASDAQ: INVA), announced the U.S. Food and Drug Administration (FDA) approval of Nuzolvence (zoliflodacin) for oral suspension, a first-in-class, single-dose oral medication for the treatment of uncomplicated urogenital gonorrhea in adults and pediatric patients 12 years and older weighing at least 35 kg. The development of Nuzolvence was part of a private, not-for-profit collaboration with The Global Antibiotic Research and Development Partnership (GARDP), which sponsored and led the Phase 3 clinical trial that supported FDA approval.
“The FDA’s approval of Nuzolvence marks a pivotal moment for patients and the broader healthcare community managing gonorrhea infections. For the first time in decades, both patients and their healthcare providers will have a single-dose, oral treatment option for uncomplicated urogenital gonorrhea,” said David Altarac, M.D., Chief Medical Officer, Innoviva Specialty Therapeutics. “This achievement underscores our commitment to advancing innovative therapies for infectious diseases and fighting antimicrobial resistance. It highlights the strength of our development capabilities, as well as our collaboration with GARDP and the global scientific community.”
Gonorrhea is the second most common sexually transmitted bacterial infection worldwide, with more than 82 million new cases each year. In the United States alone, the Centers for Disease Control and Prevention (CDC) estimates that over 543,000 cases are reported each year and over 1 million incident cases occur annually,3 underscoring the significant public health impact. The highest rates are seen among sexually active men ages 20-24, though anyone who has unprotected sex can be at risk.4 Without timely treatment, gonorrhea can lead to serious and potentially permanent health complications.
"The decades-long absence of new gonorrhea treatments, combined with rising global antibiotic resistance, has created significant challenges in managing this common but potentially serious sexually transmitted infection," said Edward W. Hook III, M.D., Professor Emeritus of Medicine, University of Alabama at Birmingham, and lead investigator of the Phase 3 Nuzolvence trial. “In the pivotal Phase 3 study, Nuzolvence demonstrated non-inferiority compared to the current standard injectable therapy, including in infections caused by drug-resistant strains, while offering the convenience of a single oral dose.”
“A new antibiotic that does not require injection and can be used for patients who are allergic to penicillin or related drugs meets two important unmet needs in the treatment of gonorrhea,” added Dr. Hook.
The emergence and spread of global drug-resistant infections have led the World Health Organization (WHO) to identify antimicrobial resistance as one of the 10 most critical global health threats.5 The bacterium Neisseria gonorrhoeae has developed resistance to most classes of antibiotics used to treat these infections, including cephalosporins such as ceftriaxone, an injectable treatment, which is the currently recommended first line therapy for uncomplicated urogenital gonorrhea.
The Company plans to commercialize Nuzolvence in the second half of 2026, either in collaboration with a commercialization partner or independently.
