GSK Reports Positive Phase III Results for Gepotidacin in Treating Uncomplicated Urogenital Gonorrhea

GlaxoSmithKline (GSK) has announced promising results from the critical EAGLE-1 phase III trial for gepotidacin, a potential first-in-class oral antibiotic for the treatment of uncomplicated urogenital gonorrhea in adolescents and adults. The trial showed that gepotidacin achieved a 92.6% microbiological success rate, which was non-inferior to the leading combination treatment of intramuscular ceftriaxone and oral azithromycin.

Gepotidacin, with its novel mechanism of action, inhibits bacterial DNA replication differently from other antibiotics, making it a promising new treatment option for gonorrhea, which is becoming increasingly resistant to existing antibiotics. The safety and tolerability profile of gepotidacin was consistent with previous trials, with the most commonly reported adverse events being gastrointestinal.

Why this matters: Gonorrhea is a growing global health concern, with rising incidence and antibiotic resistance. The development of new treatment options, such as gepotidacin, is imperative in addressing this sexually transmitted infection that can lead to infertility and other complications if not adequately treated.

The EAGLE-1 trial is the third critical or central trial for gepotidacin, which is part of GSK's infectious diseases portfolio. The development of gepotidacin has been funded in part by the U.S. Department of Health and Human Services and the Defense Threat Reduction Agency.
