Iterum Therapeutics Announces Completion of Enrollment in its REASSURE Phase 3 Clinical Trial of Oral Sulopenem in Uncomplicated Urinary Tract Infections
October 24 2023 - 8:00AM
Iterum Therapeutics plc (Nasdaq: ITRM) (Iterum), a clinical-stage
pharmaceutical company focused on developing next generation oral
and IV antibiotics to treat infections caused by multi-drug
resistant pathogens in both community and hospital settings, today
announced the completion of patient enrollment in its REASSURE
(
REnewed
ASsessment of
Sulopenem in u
UTI caused by
Resistant
Enterobacterales)
clinical trial comparing oral sulopenem (sulopenem etzadroxil
combined with probenecid in a bilayer tablet) to oral Augmentin®
(amoxicillin/clavulanate) in adult women with uncomplicated urinary
tract infections (uUTI).
“We are extremely pleased to have completed enrollment in our
REASSURE trial well ahead of schedule. We now expect topline
results early in the first quarter of 2024, and subject to our
analysis of the data, plan to resubmit our NDA to the FDA in the
second quarter of 2024,” said Corey Fishman, Chief Executive
Officer. “This significant milestone represents another exciting
step forward in the development of oral sulopenem and potentially
bringing to market the first antibiotic approved for the treatment
of uUTIs in over 25 years, as well as the first oral penem, in the
U.S.”
Iterum expects to report topline data early in the first quarter
of 2024 and, subject to its analysis of the data, to resubmit its
New Drug Application (NDA) for oral sulopenem for the treatment of
uUTIs to the U.S. Food and Drug Administration (FDA) in the second
quarter of 2024. Provided that the resubmitted NDA addresses all of
the deficiencies identified in the complete response letter Iterum
received from the FDA in July 2021, Iterum expects that the FDA
will complete its review and take action six months from the date
the FDA receives the resubmitted NDA (or during the second half of
2024).
About REASSURE
The REASSURE trial is designed as a non-inferiority trial
comparing oral sulopenem and Augmentin® in the Augmentin
susceptible population and is entitled “A prospective, Phase 3,
randomized, multi-center, double-blind study of the efficacy,
tolerability, and safety of oral sulopenem etzadroxil/probenecid
versus oral amoxicillin/clavulanate for treatment of uncomplicated
urinary tract infections (uUTI) in adult women.” Patients were
randomized to receive either oral sulopenem twice daily for 5 days
or Augmentin® twice daily for 5 days. The primary endpoint is the
overall response (clinical and microbiologic combined response) at
the test of cure visit. The trial enrolled approximately 2,230
patients and is being conducted under a special protocol assessment
(SPA) agreement with the FDA.

About Urinary Tract Infections (UTIs)
UTIs are among the most common bacterial infections encountered
in the community. There are approximately 15 million emergency
room and office visits for symptoms of urinary tract infections and
approximately 33 million uUTIs treated in the United States
annually, with approximately 30% of those infections caused by a
quinolone non-susceptible organism, and approximately 1% of those
infections caused by pathogens that are resistant to all commonly
available classes of oral antibiotics. As a result, the treatment
of UTIs has become more challenging because of the development of
resistance by pathogens responsible for these infections. uUTIs are
infections of the bladder occurring mainly in women. 50% of all
women experience at least one UTI at some point in their lives.
