AEON Biopharma FDA Type 2b Meeting Feedback Clarifies Biosimilar Development Plan for ABP-450
AEON Biopharma received official FDA minutes from its Type 2b biosimilar meeting on ABP-450, which clarify and potentially streamline the path to a 351(k) BLA submission for full-label therapeutic use as a BOTOX biosimilar.
The FDA agreed in principle with a two-stage CMAP pharmacodynamic study design and said previously completed head-to-head studies versus BOTOX can be submitted as supportive evidence, subject to scientific bridging. AEON does not plan a standalone comparative efficacy study at this time, citing FDA's October 2025 draft guidance.
Key milestones include IND filing for the CMAP PD study in Q4 2026, study initiation in Q1 2027, and returning to the FDA in 2027 with an integrated evidence package.
The U.S. therapeutic neurotoxin market exceeds $3.0 billion annually, making a streamlined pathway a significant capital-efficiency win for the clinical-stage company.
