Fezolinetant effective treatment of vasomotor symptoms associated with menopause
A study by Kimball A Johnson and peers found fezolinetant to be a safe and effective treatment for moderate-to-severe vasomotor symptoms (VMS) associated with menopause. The findings were published in The Journal of Clinical Endocrinology & Metabolism.
The clinical trial evaluated the efficacy and safety of fezolinetant, a drug for the treatment of moderate-to-severe vasomotor symptoms (VMS) associated with menopause. The trial included women between the ages of 40-65 who experienced at least 7 moderate-to-severe VMS per day.
The study was a double-blind, placebo-controlled 12-week trial, followed by a 40-week active treatment extension. Participants were randomized to receive placebo, fezolinetant 30 mg, or fezolinetant 45 mg daily for the initial 12 weeks. After the initial 12 weeks, participants who completed the trial were rerandomized to receive fezolinetant for an additional 40 weeks. The primary endpoints were the mean daily change from baseline in VMS frequency and severity at weeks 4 and 12.
The results showed that both fezolinetant doses were effective in reducing VMS frequency and severity compared to placebo at week 4 and week 12. The reduction in VMS frequency and severity was statistically significant for both doses at both time points. Moreover, improvement in VMS frequency and severity was observed as early as week 1 and was maintained through week 52. The drug was well-tolerated with few serious adverse events reported.
The Authors found these results important as VMS can be debilitating and have a significant impact on the quality of life of women experiencing menopause. The availability of an effective and well-tolerated treatment can provide relief for many women suffering from VMS.
