Acurx Secures FDA and USPTO Nod for CIFBEZY Brand Name
Event summary
- FDA conditionally accepted the brand name CIFBEZY for ibezapolstat, Acurx's lead antibiotic candidate for C. difficile infection (CDI).
- USPTO allowed the trademark application for CIFBEZY, securing intellectual property protection.
- Ibezapolstat is preparing to advance into international Phase 3 clinical trials for both acute treatment and reduction of recurrence of CDI.
- FDA guidance suggests a single Phase 3 trial could support NDA filing for both indications.
- Acurx aims to initiate a ground-breaking clinical trial in patients with multiply-recurrent CDI (rCDI) in the coming months.
The big picture
Acurx's progress with CIFBEZY and ibezapolstat comes as the biopharmaceutical industry faces increasing pressure to develop novel antibiotics amid rising antibiotic resistance. The FDA's conditional acceptance and USPTO's trademark allowance are critical milestones that position Acurx to capitalize on the unmet medical need for more effective CDI treatments. With recurrent CDI posing a significant public health and economic burden, ibezapolstat's potential to address both acute treatment and recurrence prevention could offer substantial in-market competitiveness if clinical trials succeed.
