Unverified record. The outcome below was inferred from the share-price reaction around this date. Nobody has confirmed it against an FDA, SEC or company document, and it may be wrong: we have published at least one inferred outcome that turned out to be impossible (see corrections). Treat it as a price observation, not as a regulatory fact. Verified decisions on this site always link a primary source.
