Fezolinetant: a novel nonhormonal therapy for vasomotor symptoms due to menopause.

Placebo-controlled studies demonstrated that fezolinetant led to a statistically significant reduction in vasomotor symptom frequency and severity among patients with moderate-to-severe vasomotor symptoms. The most common adverse event is headache (5-10%) and no serious safety signals have been noted. Direct head-to-head comparison with hormonal therapies and nonhormonal therapies for vasomotor symptoms, assessment of sleep outcomes, and evaluation of efficacy and safety beyond 1 year are key areas where additional data are still needed.
