GSK Blujepa bags USFDA nod for treatment of uUTIs in female adults, paediatric patients 12 years of age and older
London: GSK plc has announced that the Company has received US Food and Drug Administration (FDA) approval for 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 the following susceptible microorganisms: Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii complex, Staphylococcus saprophyticus and Enterococcus faecalis.
Discovered by GSK scientists, 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.
Thomas Hooton, MD, Professor of Clinical Medicine, University of Miami School of Medicine said, “For many, uUTIs can be a burden that severely impacts daily life. With an increasing number of patients experiencing recurrent infections, there remains a clear need for continued research of antimicrobials to help address ongoing patient challenges and the strain on healthcare systems.”
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 (covariate-adjusted treatment difference 4.3%, 95% CI (-3.6, 12.1)). In EAGLE-3, Blujepa demonstrated statistically significant superiority versus nitrofurantoin (one-sided p-value 0.0003). Therapeutic success occurred in 58.5% (162/277) of participants compared to 43.6% (115/264) for nitrofurantoin (covariate-adjusted treatment difference 14.6%, 95% CI (6.4, 22.8)).
The safety and tolerability profile of Blujepa in the EAGLE-2 and EAGLE-3 phase III trials was consistent with previous trials.
US commercial launch is planned in 2H 2025.
The development of Blujepa (gepotidacin) has been funded in part with federal funds from the US Department of Health and Human Services, Administration for Strategic Preparedness and Response, Biomedical Advanced Research and Development Authority (BARDA), under Other Transaction Agreement number HHSO100201300011C and with federal funds awarded by the Defense Threat Reduction Agency under agreement number HDTRA1-07-9-0002.
Blujepa, discovered by GSK scientists, is a bactericidal, first-in-class triazaacenaphthylene antibiotic that inhibits bacterial DNA replication by a distinct binding site, a novel mechanism of action and for most pathogens, provides well-balanced inhibition of two different Type II topoisomerase enzymes. This provides activity against most target uropathogens (such as Escherichia coli and Staphylococcus saprophyticus), and Neisseria gonorrhoeae, including isolates resistant to current antibiotics. Due to the well-balanced inhibition for most pathogens, Blujepa target-specific mutations in both enzymes are needed to significantly affect susceptibility to Blujepa. Therefore, a lower potential for resistance development is expected. Efficacy and safety in patients have been demonstrated in uUTI and gonorrhoea phase III clinical trials, including in patients with drug-resistant pathogens.
