Question · Q4 2025
Luke asked about the clinical endpoints for ARV-102 in PSP, including early ones and what regulators seek for a registrational trial, and if there's a backup commercialization plan for vepdegestrant if a collaboration isn't secured by the PDUFA date.
Answer
President and CEO Randy Teel confirmed that the vepdegestrant partnership process is moving well with Pfizer, and a backup plan is on their radar if needed. Chief Medical Officer Noah Berkowitz stated that the PSP rating scale is the gold standard endpoint for PSP, and while the Phase 1B won't be fully powered, it will identify trends. He also mentioned incorporating eye movement and muscle movement indicators into studies for their predictive potential.
