About this register

This register is built from the EU Clinical Trials Information System (CTIS), run by the European Medicines Agency: the single register for every trial authorised under the EU Clinical Trials Regulation (536/2014). CTIS held 12,561 trial records at the last sync on 06 Oct 2026, 03:17 UTC; this register shows the 2,557 most recently authorised of them, a stated recency window rather than the full archive. The list can be downloaded as CSV or JSON.

This page shows the 166 of those trials with a site in Portugal.

How many recently authorised EU trials have a site in Portugal?

166 of the 2,557 most recently authorised trials in this register list a site in Portugal; 110 of them are Phase III. Trials are counted by authorisation on CTIS, not by recruitment status, which CTIS does not publish in the same form as ClinicalTrials.gov.
