US FDA approves gepotidacin, a first-in-class antibiotic for UTIs in women
Gepotidacin has recently been approved by the US Food and Drug Administration (FDA) - the first in a new class of oral antibiotics for adult females with uncomplicated UTIs. This new treatment option is appropriate for uUTIs caused by: Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii complex, Staphylococcus saprophyticus, and Enterococcus faecalis. It has also been approved for use in children ≥12 years of age weighing at least 40 kg.
Gepotidacin is a first-in-class triazaacenaphthylene bacterial type II topoisomerase inhibitor with a novel mechanism of action; inhibiting bacterial DNA replication by blocking two essential topoisomerase enzymes. Mutations in both enzymes would likely be necessary for resistance to occur, raising hopes that the drug will be able to maintain long-term effectiveness and have a lower potential for resistance.
In two randomized clinical trials (EAGLE-2 and EAGLE-3), gepotidacin was noninferior to nitrofurantoin in both studies and superior to nitrofurantoin in EAGLE-3.[88]
Gepotidacin has the potential to cause QTc prolongation, so should be avoided in patients with a history of QTc prolongation, or those with relevant pre-existing cardiac disease, and in patients receiving drugs that prolong the QTc interval. It also should be avoided in patients taking strong CYP3A4 inhibitors, in patients with severe hepatic impairment (Child-Pugh Class C), and in patients with severe renal impairment (estimated glomerular filtration rate [eGFR] <30 mL/min).
Urinary tract infections (UTIs) are among the most common conditions encountered by clinicians across a range of settings. The development of gepotidacin marks a major milestone, as it is the first new oral antibiotic for UTIs in more than 20 years. It is anticipated that gepotidacin will be available in the US in the second half of 2025. Gepotidacin has not been approved in Europe as yet.
