Outcome Measures
Primary Outcome Measures
- To understand the relationship between baseline biology and score change in the Montgomery-Asberg Depression Rating Scale (MADRS) with ALTO-100 from start of dosing to end of treatment [Measured at Day 1, Day 14, Day 28, Day 42, Day 56]
The Montgomery-Åsberg Depression Rating Scale (MADRS) measures the severity of depression where smaller scores indicate less depression and higher scores suggest more severe depression. Possible scores for this 10 item version range from 0 to 60. The score change from the start of dosing (Day 1) to the end of treatment (Day 56) is the primary outcome.
- To understand the relationship between baseline biology and score change in the Clinical Global Impression scale - Severity (CGI-S) with ALTO-100 from Screening to end of treatment [Measured at Screening, Day 1, Day 14, Day 28, Day 42, Day 56]
The Clinical Global Impression scale - Severity (CGI-S) measures the severity of psychopathology in general where smaller scores indicate less illness and higher scores suggest more severe illness. Possible scores for this scale range from 1 to 7. The score change from Screening (Day [-21]) to the end of treatment (Day 56) is the primary outcome.
- Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability of ALTO-100 [From the signing of the ICF until the follow-up visit (up to 13 weeks)]
An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
- Number of Participants With Clinically Significant Laboratory Abnormalities as a Measure of Safety and Tolerability of ALTO-100 [From the signing of the ICF until the end-of-treatment visit (up to 13 weeks)]
Blood samples for serum chemistry and hematology will be collected for clinical laboratory testing.
