Acurx Pharmaceuticals Inc. continues to post positive data for its lead candidate ibezapolstat but that didn’t stop the stock from tumbling. The antibiotic outperformed vancomycin in a phase IIb study treating Clostridioides difficile infection (CDI). Vancomycin is a standard of care in the indication. Ibezapolstat eradicated fecal CDI at day 3 in 15 of 16 patients compared to vancomycin, which eradicated fecal CDI in 10 of 14 patients.
