Clinical Trials in Bulgaria, 2026

The most recently authorised trials on the EU Clinical Trials Information System (CTIS), the single register for every trial run under the EU Clinical Trials Regulation (536/2014). CTIS holds a far larger historical archive than any one list can usefully show — this register states both numbers rather than picking one.

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 12,594 trial records at the last sync on 10 Oct 2026, 03:17 UTC; this register shows the 2,558 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 0 of those trials with a site in Bulgaria that also match the filters currently applied.

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

0 of the 2,558 most recently authorised trials in this register list a site in Bulgaria and match the filters applied; 0 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.

Listing here is informational and not medical advice; eligibility is determined by each study team. Looking for Irish sites? See the Ireland, UK or USA registers. For approved medicines, see the EMA Approvals Tracker.
