Why it may matterVerify against the original reporting
The key catalyst is progression toward a registrational Phase 3 readout (ELAINE-3) with topline data expected in 2H2027, plus a financing backdrop that could extend cash runway via warrant exercise. If enrollment remains on track and early signals hint at efficacy, the stock could re-rate on reduced clinical/margin uncertainty and anticipated regulatory milestones. Historical precedents show Phase 3 readouts in oncology driving multi-bounce moves, tempered by execution risk and cash-burn concerns.
