`ct_recent_updates`

Pack: clinicaltrials · Endpoint: https://gateway.pipeworx.io/clinicaltrials/mcp

Track recent ClinicalTrials.gov activity by a specific event class within a verifiable date window. Three DISTINCT recency events, chosen via date_type: “last_update” (any edit to a study, ~5k/week — the default), “first_posted” (a study newly REGISTERED, ~1.3k/week), or “results_posted” (RESULTS first posted, ~140/week). Pass since (and optional until, YYYY-MM-DD) to bound a window — e.g. the last 7 days — and the returned total_count is the exact number of studies in that window so you can verify a weekly count from the output. Every study returns all THREE dates separately (first_posted_date, last_update_post_date, results_first_post_date) plus the design fields a screen needs (study_type, primary_purpose, phase, status, enrollment, conditions, interventions, sponsor). Sorted by the chosen event date, newest first. Use for “new trials registered this week”, “trials that posted results in the last month”, “recently updated diabetes studies”.

Parameters

Name	Type	Required	Description
`date_type`	string	no	Which recency event to track/sort/window by: “last_update” (any edit, default), “first_posted” (new registration), “results_posted” (results first posted). These are different event classes with very different volumes — pick deliberately.
`since`	string	no	Window start (inclusive), YYYY-MM-DD. e.g. for a weekly review pass 7 days ago. Applies to the chosen date_type.
`until`	string	no	Optional window end (inclusive), YYYY-MM-DD. Omit for open-ended (up to today).
`status`	string	no	Optional overall-status filter (validated; e.g. RECRUITING, or a comma-union like “RECRUITING,COMPLETED”).
`query`	string	no	Optional search term (condition/drug/keyword) to narrow results.
`limit`	number	no	Number of results per page (1-100, default 20). total_count reports the full window size regardless of limit.
