Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In the present study, 120 healthy volunteers (HV) will be randomized to one of three ketamine-induced pharmacoBOLD (phBOLD) arms: low, medium, and high. Within each ketamine arm, participants will be randomized to 4 days of "study drug" \[TS-134 (1st 20 participants) or XT (remaining 100 participants)\] or placebo in a 5:3 ratio (25 study drug:15 placebo per arm). During the study, each participant will undergo a Screening Period (up to 31 days), a 4-day Treatment Period, and a total of two phBOLD sessions: a first session at Baseline and a second session on Day 4 of the Treatment Period, conducted at least 7 days apart, and a follow up visit.
