NCT06391593
Brief Summary:
The goal of this clinical trial is to determine the pharmacodynamic effects of ALTO-203 in patients with MDD in a randomized, placebo-controlled, single-dose crossover treatment period. Additionally, safety, tolerability, and PK will be assessed in a subsequent randomized placebo-controlled multi-dose parallel-group treatment period of 28 days.
Participants will complete subjective response questionnaires and perform cognitive tasks during the single-dose period, in which participants will receive ALTO-203 25 μg and 75 μg, as well as placebo. During the multiple-dose period, participants will receive either ALTO-203 25 μg, 75 μg , or placebo. Safety will be assessed over the single dose and 28-day multiple dose periods.
