The positive CMC feedback reduces regulatory risk ahead of the End-of-Phase 2 meeting in mid-2026, potentially supporting a near-term valuation re-rate. Monitor for trial design confirmation and funding plans for the Phase 3 program.

Executive Summary
Alterity Therapeutics received positive FDA feedback on the chemistry, manufacturing, and control (CMC) aspects of its ATH434 Phase 3 program for Multiple System Atrophy (MSA), supporting readiness for trial initiation and manufacturing scale-up. This follows a prior Type C meeting on clinical pharmacology, with an End-of-Phase 2 meeting still on track for mid-2026.
Key Facts

- This is the second Type C meeting with the FDA, following one in March on clinical pharmacology.
- End-of-Phase 2 meeting remains on track for mid-2026.
- ATH434 has shown clinically meaningful efficacy in a Phase 2 randomized trial and positive open-label data in advanced MSA.

Risk Factors
- Phase 3 trial has not yet started; clinical execution and funding risks remain.
- No guaranteed outcome from the End-of-Phase 2 meeting in 2026.
