The co-primary efficacy endpoints for both trials were the mean change from baseline in moderate to severe vasomotor symptoms frequency and severity to Weeks 4 and 12. Data from each trial demonstrated statistically significant and clinically meaningful (≥ 2 hot flashes over 24 hours) reduction from baseline in the frequency of moderate to severe vasomotor symptoms for Fezolinetant 45 mg compared to placebo at Weeks 4 and 12.
Data from each trial also demonstrated a statistically significant reduction from baseline in the severity of moderate to severe vasomotor symptoms (over 24 hours) at Weeks 4 and 12 for Fezolinetant 45 mg compared to placebo.
