Acurx Announces Publication in the Nature Communications Scientific Journal Documenting its Unique Targeting of DNA pol IIIC Gram-positive Priority Pathogens
Introduction of New Antibiotics: Acurx Pharmaceuticals is developing a new class of antibiotics, DNA polymerase IIIC inhibitors, targeting Gram-positive bacteria such as C. difficile, MRSA, and VRE, with their lead candidate, ibezapolstat, showing promising Phase 2 results for treating C. difficile infections.
Clinical Trial Success: Ibezapolstat demonstrated a 96% clinical cure rate in Phase 2 trials, with no recurrence of infection, and is now ready for Phase 3 trials in the U.S. and EU, supported by positive regulatory feedback from the FDA and EMA.
Research Collaboration: Acurx's collaboration with Leiden University Medical Center has provided structural insights into ibezapolstat's mechanism of action, aiding the development of new antibiotics against multi-drug-resistant pathogens.
Microbiome Preservation: Ibezapolstat treatment appears to maintain a healthy gut microbiome, showing favorable changes in bile acid metabolism that may reduce the likelihood of C. difficile recurrence compared to traditional treatments like vancomycin.
