Blujepa approved by US FDA for treatment of uncomplicated urinary tract infections

The US Food and Drug Administration (FDA) has approved GSK’s Blujepa (gepotidacin) for the treatment of female adults (≥40 kg) and paediatric patients (≥12 years, ≥40 kg) with uncomplicated urinary tract infections (uUTIs) caused by Escherichia coliKlebsiella pneumoniae, Citrobacter freundii complex, Staphylococcus saprophyticus and Enterococcus faecalis.

Blujepa is a first-in-class oral antibiotic with a novel mechanism of action that is part of GSK’s infectious diseases portfolio.

Tony Wood, Chief Scientific Officer, GSK, said: “The approval of Blujepa is a crucial milestone with uUTIs among the most common infections in women. We are proud to have developed Blujepa, the first in a new class of oral antibiotics for uUTIs in nearly three decades, and to bring another option to patients given recurrent infections and rising rates of resistance to existing treatments.”

uUTIs are the most common infection in women, impacting up to 16 million women in the US annually. Over half of all women are affected by uUTI in their lifetime, with approximately 30% suffering from at least one recurrent episode which can cause significant patient burden, including discomfort and restriction of daily activities. New treatments are needed as the number of uUTIs caused by drug-resistant bacteria is increasing which can result in higher treatment failure rates.

The approval is based on positive results from the pivotal phase III EAGLE-2 and EAGLE-3 trials which demonstrated non-inferiority to nitrofurantoin, one of the leading current standard of care options for uUTI, in female adults (≥40 kg) and paediatric patients (≥12 years, ≥40 kg) with a confirmed uUTI.

In EAGLE-2, Blujepa demonstrated non-inferiority in therapeutic success which occurred in 50.6% (162/320) of participants compared to 47.0% (135/287) for nitrofurantoin. In EAGLE-3, Blujepa demonstrated statistically significant superiority versus nitrofurantoin. Therapeutic success occurred in 58.5% (162/277) of participants compared to 43.6% (115/264) for nitrofurantoin.

The safety and tolerability profile of Blujepa in the EAGLE-2 and EAGLE-3 phase III trials was consistent with previous trials. The most commonly reported adverse events (AEs) in Blujepa participants were gastrointestinal (GI). Diarrhoea was the most common (16% of participants), followed by nausea (9%).

Of the participants who reported GI AEs in the Blujepa group, the most common maximum severity was mild (69% Grade 1) and moderate (28% Grade 2). Participants with Grade 3 GI events accounted for 3% of all patients with GI events and occurred in <1% of all participants. There was one drug-related serious adverse event in each treatment arm (Blujepa and nitrofurantoin) across the two trials.
