Psychedelic and ketamine research trials in Belgium
Data as of 11 October 2026. Source: ClinicalTrials.gov records held by PsychoactiveMap, refreshed from a reviewed snapshot.
5 registered studies are counted in Belgium. By compound: 2 psilocybin and 3 ketamine. By registry status: 1 recruiting, 1 completed, 1 terminated and 2 status not reported. By phase: 4 phase 2 and 1 not reported. Reported start years run from 2012 (earliest) to 2024 (latest). Studies are linked to 5 institutions.
Country is taken from the research site linked to each registry record. A study counts once, and a study tagged with more than one compound is counted under each compound. Ketamine studies are counted only when PsychoactiveMap classifies them as psychiatric research; anaesthesia, sedation and pain studies are left out.
Educational information, not medical advice. A registry listing is not evidence of safety, benefit or results, and it is not a recommendation. PsychoactiveMap does not recruit, screen or refer participants. Status and other details are copied from the registry and can be out of date, so check the registry record and speak to a qualified health professional before any decision. Read the full disclaimer.

About this data
Compound tags come from automated matching of the registry search term and have not been checked record by record. Counts are of registered studies, not of people, results or approvals. A registry listing is not evidence of safety, benefit or results.
