What this trial studies
The primary purpose of this study was to evaluate the effect of ESN364 on the severity and frequency of hot flashes in early postmenopausal women suffering from hot flashes, in terms of changes in weekly Hot Flash Score from baseline to Week 12. This study also evaluated the effect of ESN364 on the severity and frequency of hot flashes at additional timepoints; hot flash interference on daily life, in terms of changes from baseline over time in Hot Flash Related Daily Interference Scale (HFRDIS); the effect of ESN364 on climacteric symptoms, in terms of changes from baseline over time in Leeds Sleep Evaluation Questionnaire (LSEQ), Greene Climacteric Scale (GCS), and Sheehan Disability Scale (SDS); pharmacodynamic (PD) effect; and safety and tolerability.

Outcome measures
Primary outcomes
- Change From Baseline to Week 12 in The Weekly General Hot Flash Score (Baseline and week 12)
The HF score (based on severity and frequency) was calculated as: (number of mild HF/day × 1) + (number of moderate HF/day × 2) + (number of severe HF/day × 3) The severity of HFs is clinically defined as follows: * Mild: sensation of heat without sweating/dampness. If at night, participant didn't wake up but later notices damp sheets or…
