Why it may matterVerify against the original reporting

The combination of Phase 3 regulatory progress, FDA Orphan Drug Designation, and a substantial financing deal improves near-term visibility on the PAH program and reduces burn risk, which could drive a re-rate contingent on topline data readouts.
