How to read this

Deeper blue means more of the thesis turns on the event — not a view on the stock and not a prediction of the outcome. A thesis-defining readout and a routine trial start are both just events until they report.

Dates reflect company guidance as reported in Biotech Distilled coverage and are frequently windows rather than fixed dates. Not investment advice.
