OK

- FdaCatalystDtoListResponse
  - `listingNotice` ListingNotice: What happened to a requested ticker that no longer trades. "delisted": the company has no current US listing, so the answer is its history. "renamed": the company now trades as successorTicker, its current US presentation ticker (possibly another share class). A listed series (short volume, short interest, off-exchange volume, fails-to-deliver, congressional trades) is the retired ticker's own; a company-level read is the company's data.
    - `status` string, nullable: "delisted" or "renamed".
    - `ticker` string, nullable: The retired ticker as listed.
    - `delistedOn` string, date, nullable: The day the retired listing stopped trading, when known.
    - `successorTicker` string, nullable: For "renamed", the company's current US presentation ticker; null for "delisted".
  - `data` FdaCatalystDto[], nullable
    - `meetingDate` string, date: First day of the meeting.
    - `endDate` string, date, nullable: Last day of the meeting; null when the calendar lists no distinct end.
    - `title` string, nullable: Meeting title as announced by the FDA (usually a committee announcement, not a drug name).
    - `center` string, nullable: FDA organizational center, e.g. "Center for Drug Evaluation and Research".
    - `catalystType` string, nullable: Human-readable catalyst type, e.g. "Advisory Committee Meeting".
    - `sourceUrl` string, nullable: The FDA.gov page for this meeting — the only place the product/sponsor under review is identified.
