This is a significant pipeline catalyst update for a mid-cap biotech. The Phase 3 initiation by year-end and the $1-3B peak revenue estimate provide a clear long-term value thesis. Traders should watch for Cornerstone enrollment updates and potential partnership or financing announcements as the company funds the program itself. The stock has strong historical momentum on positive news (100% win rate on prior reports).
