Data demonstrated beneficial bacterial taxa persist in fecal samples from patients with rCDI despite multiple prior CDI treatments with the antibiotic standards of care, vancomycin (VAN) and/or fidaxomicin (FDX)
Following acute treatment with ibezapolstat (IBZ), these beneficial microorganisms will have the opportunity to repopulate the microbiome in a beneficial way that may prevent recurrence
IBZ and FDX were superior in biofilm experimental models with IBZ significantly more effective at killing C. difficile than VAN and FDX
Trial start-up activities for a ground-breaking clinical trial in patients with multiply-recurrent CDI (rCDI) have been initiated with the first patient expected to enroll in the next quarter; a successful trial outcome has the potential to shift the paradigm of treatment and prevention of rCDI from two agents to one
With mutually consistent feedback from both EMA and FDA, Acurx is well positioned to commence its international Phase 3 registration program in the broader CDI patient population ("acute CDI")
Acurx has previously been granted FDA QIDP and Fast-Track Designation and has received SME (Small and Medium-sized Enterprise) designation by the EMA
STATEN ISLAND, N.Y., July 14, 2026 /PRNewswire/ -- Acurx Pharmaceuticals, Inc. (NASDAQ: ACXP) a clinical stage biopharmaceutical company developing a new class of antibiotics for difficult-to-treat bacterial infections, announced today that a poster presentation entitled: Microbiome Restoration Potential of Ibezapolstat vs. Comparator Antibiotics in Patients with Multiply-recurrent Clostridioides difficile Infection (CDI) was presented by Kevin Garey, PharmD, MS, FIDSA, Professor and Chair, University of Houston College of Pharmacy, Principal Investigator for microbiology and microbiome aspects of the IBZ clinical trial program at the 18th Biennial Congress of the Anaerobe Society of the Americas held at Columbia University Irving Medical Center in New York City from July 8 to 10, 2026.
Studies were performed at the University of Houston to determine whether beneficial gut microbes are present in patients with multiple (≥2) recurrences of Clostridioides difficile infection (rCDI). The objectives of this study were to determine whether beneficial microbes identified in the IBZ Phase 2 studies in patients with initial and 1st recurrent CDI are still present in patients with multiple (≥2) recurrent CDI and to assess killing effects of IBZ vs. comparators in planktonic (non-biofilm) and biofilm mono- and duo-culture studies; specifically, measuring killing of VRE by VAN, FDX, and IBZ in planktonic and biofilm cultures.
