Trial Outcomes & Findings for Glutamate Reducing Interventions in Schizophrenia (NCT NCT03321617)
NCT ID: NCT03321617
Last Updated: 2021-12-01
Results Overview
Effect of POMA on left CA1 CBV as measured by percent change from baseline scan (Time 1) to Day 14 scan (Time 2)
COMPLETED
PHASE1
16 participants
Baseline to 14 days of POMA/placebo
2021-12-01
Participant Flow
5 participants consented to the protocol and underwent screening procedures but were not randomized (did not receive study medication). Reasons for screen fail: 1-withdrew consent 1-unable to undergo scan 3-study was paused due to COVID-19 pandemic
