About the Ibezapolstat Phase 2 Clinical Trial
The completed multicenter, open-label single-arm segment (Phase
2a) study was followed by a double-blind, randomized,
active-controlled, non-inferiority, segment (Phase 2b) at 28 US clinical trial sites which together
comprise the Phase 2 clinical trial
(see https://clinicaltrials.gov/ct2/show/NCT04247542). This
Phase 2 clinical trial was designed to evaluate the clinical
efficacy of ibezapolstat in the treatment of CDI including
pharmacokinetics and microbiome changes from baseline
and continue to test for anti-recurrence
microbiome properties seen in
the Phase 2a trial, including the treatment-related changes
in alpha diversity and bacterial abundance and
effects on bile acid metabolism.
The completed Phase 2a segment of this trial was an open label
cohort of up to 20 subjects from study centers in the United States. In this cohort, 10 patients
with diarrhea caused by C. difficile were treated with
ibezapolstat 450 mg orally, twice daily for 10 days. All patients
were followed for recurrence for 28± 2 days. Per protocol, after 10
patients of the projected 20 Phase 2a patients completed treatment
(100% cured infection at End of Treatment), the Trial Oversight
Committee assessed the safety and tolerability and made its
recommendation regarding early termination of the Phase 2a study
and advancement to the Ph2b segment. In the now completed Phase
2b trial segment, 32 patients with
CDI were enrolled and randomized in a 1:1 ratio to either
ibezapolstat 450 mg every 12 hours or vancomycin 125 mg orally
every 6 hours, in each case, for 10 days and followed for 28 ± 2
days following the end of treatment for recurrence of CDI. The two
treatments were identical in appearance, dosing times, and number
of capsules administered to maintain the blind. This Phase 2
clinical trial will also evaluate pharmacokinetics (PK) and
microbiome changes and test for anti-recurrence microbiome
properties, including the change from baseline in alpha diversity
and bacterial abundance, especially overgrowth of healthy gut
microbiota Actinobacteria and Firmicute phylum species during and
after therapy. In the event non-inferiority of ibezapolstat to
vancomycin is demonstrated, further analysis will be conducted to
test for superiority.
Phase 2a data demonstrated complete eradication of colonic C.
difficile by day three of treatment with ibezapolstat as well
as the observed overgrowth of healthy gut microbiota,
Actinobacteria and Firmicute phyla species, during and after
therapy. Very importantly, emerging data show an increased
concentration of secondary bile acids during and following
ibezapolstat therapy which is known to correlate with colonization
resistance against C. difficile. A decrease in primary
bile acids and the favorable increase in the ratio of
secondary-to-primary bile acids suggest that ibezapolstat may
reduce the likelihood of CDI recurrence when compared to
vancomycin.
About the Microbiome in Clostridioides difficile
Infection (CDI) and Bile Acid Metabolism
C. difficile can be a normal component of the healthy gut
microbiome, but when the microbiome is thrown out of balance, the
C. difficile can thrive and cause an infection. After
colonization with C. difficile, the organism produces and
releases the main virulence factors, the two large clostridial
toxins A (TcdA) and B (TcdB). (Kachrimanidou, Microorganisms 2020,
8, 200; doi:10.3390/microorganisms8020200.) TcdA and TcdB are
exotoxins that bind to human intestinal epithelial cells and are
responsible for inflammation, fluid and mucous secretion, as well
as damage to the intestinal mucosa.
Bile acids perform many functional roles in the GI tract, with
one of the most important being maintenance of a
healthy microbiome by inhibiting C. difficile growth.
Primary bile acids, which are secreted by the liver into the
intestines, promote germination of C. difficile spores and
thereby increase the risk of recurrent CDI after successful
treatment of an initial episode. On the other hand, secondary bile
acids, which are produced by normal gut microbiota through
metabolism of primary bile acids, do not induce C. difficile
sporulation and therefore protect against recurrent disease. Since
ibezapolstat treatment leads to minimal disruption of the gut
microbiome, bacterial production of secondary bile acids continues
which may contribute to an anti-recurrence effect.
About Clostridioides difficile Infection (CDI)
According to the 2017 Update (published February 2018) of
the Clinical Practice Guidelines for C. difficile Infection by
the Infectious Diseases Society of America (IDSA) and Society
or Healthcare Epidemiology of America (SHEA), CDI remains
a significant medical problem in hospitals, in long-term care
facilities and in the community. C. difficile is one of
the most common causes of health care- associated infections in
U.S. hospitals (Lessa, et al, 2015, New England Journal
of Medicine). Recent estimates suggest C. difficile
approaches 500,000 infections annually in the U.S. and is
associated with approximately 20,000 deaths annually. (Guh, 2020,
New England Journal of Medicine). Based on internal
estimates, the recurrence rate of two of the three
antibiotics currently used to treat CDI is between 20% and 40%
among approximately 150,000 patients treated. We believe the
annual incidence of CDI in the U.S. approaches 600,000
infections and a mortality rate of approximately 9.3%.
