💊 Upcoming FDA Decisions

PDUFA DateDrugIndicationTypePoAOptions-implied move
2026-11-14 — EGFRm NSCLC Post-TKI Therapy BLA Filing Based on HARMONi Glo BLA 64% ±30% by Nov 20

Options-implied move = price of the at-the-money straddle for the first option expiry after the PDUFA date, as a share of the stock price (Yahoo Finance quotes, Oct 2). It prices every move until that expiry, not only the FDA decision.

PoA = estimated probability of approval: base rates calibrated against BioRadar's verified FDA outcomes, adjusted for application type, modality, therapy area and cash runway. Not investment advice. See the full PDUFA calendar →
