- Brief Summary
This is a double-blind, randomized, placebo-controlled, multicenter study comprised of 3 phases:screening (up to 2 weeks \[Day -15 to Day -2\]), In-Clinic Treatment (Day -1 to Day 2; including double-blind treatment \[Day 1\]), and post-treatment follow-up (7 and 14 days after infusion on Days 8 and 15, respectively). A total of 93 adult subjects with TRD will be randomly allocated in equal cohorts of 31 subjects/arm to the 3 arms of the study in a blinded manner.
