About the NBI-1070770 Phase 2 Clinical Study
The Phase 2, multicenter, randomized, double-blind, placebo-controlled study was designed to evaluate the efficacy, safety and tolerability of three dosage strengths of adjunctive NBI-1070770 compared to placebo (1:1:1:3) on improving symptoms of depression in adults with major depressive disorder who have had an inadequate response to at least one antidepressant. Participants aged 18 to 65 years were randomized to receive either NBI-1070770 or placebo for four weeks during the double-blind treatment period. The primary objective of the study was to assess the change from baseline to Day 5 in depression severity, as measured by the Montgomery-Åsberg Depression Rating Scale (MADRS).
