Cohort decision-day move (history)1.0% median (n=827)
A traditional approval, granted with Breakthrough Therapy designation and Priority Review, and the 30th novel drug approval of 2026. One practical caveat that matters for timing: the FDA has recommended the product for scheduling, and it cannot lawfully be marketed until the DEA issues its scheduling decision, so approval and availability are not the same date here.
Run-up figures are the stock's own daily closing path over the 120 trading days before the decision, from our price history. Cohort move is the historical median absolute decision-day move for this market-cap tier. History, not a prediction.
