Blujepa (gepotidacin)
approved by US FDA as oral option for treatment of uncomplicated
urogenital gonorrhoea (uGC)
●
Blujepa is
the first in a new antibiotic class for the treatment of gonorrhoea
approved in over three decades[i]
●
Offers
a new oral option for US patients with gonorrhoea currently relying
on injectable treatments
●
Neisseria
gonorrhoeae is
a priority pathogen for the World Health Organization with
significant need for new treatments[1]
GSK plc (LSE/NYSE: GSK) today announced that the US Food and Drug
Administration (FDA) has approved a supplemental New Drug
Application for gepotidacin as an oral option
for adult
and paediatric patients from 12 years of age weighing at least 45
kg who
have limited or no alternative options for the treatment of
uncomplicated urogenital gonorrhoea caused by susceptible strains
of Neisseria
gonorrhoeae (e.g.,
where standard of care is contraindicated, or where patients
are intolerant or unwilling to use first line
treatment). This
milestone follows the US FDA approval of gepotidacin earlier this
year as an oral treatment for female adult and paediatric patients
12 years of age and older (weighing ≥40 kg) with
uncomplicated urinary tract infection (uUTI).[2]
Gonorrhoea is a common, sexually transmitted infection caused
by Neisseria
gonorrhoeae,
which has been recognised by the World Health Organization as a
priority pathogen1 and
an urgent public health threat by the US Centers for Disease
Control and Prevention (CDC).[3] It
affects both men and women and if left untreated or inadequately
treated, it can lead to infertility and other sexual and
reproductive health complications. In 2023, there were over 600,000
cases of gonorrhoea reported in the United States according to the
CDC, making it the second most commonly reported sexually
transmitted infection in the country.[4] There
is currently no licensed vaccine in the US for the prevention of
gonorrhoea infections and the standard treatment relies on an
injectable antibiotic.[5]
Tony Wood, Chief Scientific Officer, GSK, said:
"We're proud to have delivered the first new class of antibiotics
for gonorrhoea in over three decades and a new oral option for US
patients. The ability of N.
gonorrhoeae to develop resistance to
currently available options, including standard of care, makes it
important to expand the range of effective oral
treatments".
The US application was based on positive results from the EAGLE-1
phase III trial which demonstrated that gepotidacin was
non-inferior to standard of care combination treatment for
gonorrhoea (intramuscular ceftriaxone plus oral azithromycin). The
trial also supported the safety and tolerability profile of
gepotidacin, with no serious drug related adverse events observed
in either the gepotidacin or the comparator arm. The most common
reported adverse reactions were mild to moderate gastrointestinal
events.[6]
With this approval, gepotidacin is now available to US patients for
the treatment of uncomplicated urogenital gonorrhoea when
appropriate.
The development of 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 based on its
potential for use against secondary bacterial infections that may
arise following chemical, biological, radiological, and nuclear
(CBRN) incidents and with federal funds awarded by the US
Department of Defense's Threat Reduction Agency under agreement
number HDTRA1-07-9-0002.
About gepotidacin
Gepotidacin, 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 Neisseria
gonorrhoeae and most target
uropathogens (such as Escherichia
coli and Staphylococcus
saprophyticus), including isolates resistant
to current antibiotics. Due to this well-balanced inhibition for
most pathogens, a single target-specific mutation may not
significantly impact gepotidacin activity.
The updated US Prescribing Information will be
available here.
About the EAGLE clinical programme
The EAGLE-1 trial (NCT04010539) is part of a comprehensive global
phase III clinical programme for gepotidacin in adults and
adolescents including:
EAGLE-1 (non-inferiority urogenital gonorrhoea trial) enrolled
approximately 600 patients with uncomplicated urogenital gonorrhoea
to compare the efficacy and safety of gepotidacin (oral, two doses
of 3,000mg) to intramuscular ceftriaxone (500mg) plus oral
azithromycin (1,000mg). The data were presented at the congress of
the European Society of Clinical Microbiology and Infectious
Diseases (ESCMID) in April 2024[7] and
published in The Lancet in April 2025.6
EAGLE-2 and EAGLE-3 (non-inferiority uUTI
trials) enrolled
approximately 3000 patients to
compare the efficacy and safety of gepotidacin (1,500mg
administered orally twice daily for five days) to nitrofurantoin
(100mg administered orally twice daily for five days). The data
were first presented at the European Congress of Clinical
Microbiology and Infectious Diseases (ECCMID) in
2023[8] and
published in The
Lancet in
February 2024.[9]
