Acurx's Ibezapolstat Shows Superior In Vitro Efficacy Against C. difficile and VRE — Acurx Pharmaceuticals, Inc.

Event summary

Acurx presented data at the 9th International C. difficile Symposium showing ibezapolstat's superior in vitro kill kinetics against C. difficile and vancomycin-resistant Enterococcus (VRE) compared to standard-of-care antibiotics vancomycin and fidaxomicin.
The study demonstrated that ibezapolstat maintained high bactericidal activity under co-culture conditions, outperforming vancomycin and fidaxomicin.
Acurx has received FDA QIDP and Fast-Track Designation and EMA SME designation for ibezapolstat.
The company is planning Phase 3 clinical trials for ibezapolstat, with a potential single trial submission for NDA approval.

The big picture

Acurx's data suggests ibezapolstat could address a critical unmet need in treating C. difficile infections, particularly in reducing recurrence and managing antibiotic resistance. The company's strategic focus on preserving the gut microbiome sets it apart in the infectious disease space. Success in Phase 3 trials could position ibezapolstat as a leading treatment option, potentially shifting the paradigm from two agents to one for both treatment and prevention of recurrent CDI.
