### [`mapEuTrialIds`](https://kirha.com/providers/ctis/mapEuTrialIds.md)

Map clinical trial identifiers between the EU registers and ClinicalTrials.gov: CTIS numbers, EudraCT numbers and NCT IDs, in any direction. Use it to join EU trials with clinicaltrials-mcp (NCT ID) or to find whether a US-registered trial runs in the EU. A trial with no counterpart returns empty lists: many EU trials have no NCT ID.

### [`searchEuTrials`](https://kirha.com/providers/ctis/searchEuTrials.md)

Search EU clinical trials in CTIS (euclinicaltrials.eu), the EU register for all trials authorised since 2023 and older EudraCT trials transitioned into it. Many are absent from ClinicalTrials.gov. Filter by condition, product, sponsor, phase, status, member state and EU start date; sorted by most recent authorisation decision by default, so it also answers 'what new EU trials were authorised'. Returns ctNumbers for getEuTrialDetails. For pre-2023 trials that never transitioned use searchEudraCtTrials.

### [`getEuTrialDetails`](https://kirha.com/providers/ctis/getEuTrialDetails.md)

Get the full CTIS record of one EU clinical trial: identifiers (EudraCT, NCT), sponsor, investigational products with ATC codes and EU authorisation numbers, conditions, primary and secondary endpoints, per-country status, status history, trial events and investigator sites, plus results availability.

### [`searchEudraCtTrials`](https://kirha.com/providers/ctis/searchEudraCtTrials.md)

Search the legacy EU Clinical Trials Register (EudraCT), which holds EU trials authorised before CTIS (2004-2023), including many never registered on ClinicalTrials.gov. Full-text query over the whole protocol (condition, substance, sponsor, NCT ID). Returns 20 trials per page and no total count. Returns eudraCtNumbers for getEudraCtTrial. Trials marked 'Trial now transitioned' continue in CTIS: use mapEuTrialIds.

### [`getEudraCtTrial`](https://kirha.com/providers/ctis/getEudraCtTrial.md)

Get the protocol of one trial from the legacy EU Clinical Trials Register (EudraCT): NCT/ISRCTN cross-references, sponsor, investigational products (INN, trade name, code), condition, phases, objective, endpoints, planned enrolment, and status plus authorisation date in each member state. Large multinational records can take ~10 s.
