/euctis/trials

POST /api/euctis/trials

Price: 20 credits

Full CTIS register record of one authorised EU/EEA clinical trial: titles, sponsors and funding, medical conditions with their MedDRA terms, therapeutic areas, objectives, primary and secondary end points, inclusion and exclusion criteria, the recruited population, investigational products with their ATC codes and marketing authorisations, study periods and arms, every member state's authorisation decision, recruitment dates and trial sites, the application history, the trial event timeline, temporary halts, unexpected events, urgent safety measures, corrective measures, the published document list and the submitted result documents.

How to use it

One trial number resolves to exactly one record, unlike the eudract register where one EudraCT number spans a record per member state — here the per-state detail is inside `member_states`, which is where recruitment dates, sites and national decisions live rather than at the top level. `result_documents` and `clinical_study_reports` are submission metadata: the result content itself is a PDF this endpoint does not return, and `documents` likewise lists what is published without fetching it. Use `nct_number`, `who_universal_trial_number` and `eudract_number` to join a trial to clinicaltrials, ictrp and eudract. A trial number that is well formed but unknown answers 412, so a 412 means the trial is not in CTIS rather than that the number was mistyped.

Parameters

Errors

• 422 — The input did not contain a CTIS trial number in the form YYYY-NNNNNN-NN-NN. Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — No CTIS trial carries that trial number. Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
