Treatment of moderate to severe vasomotor symptoms due to menopause

Vasomotor Symptoms

Menopause is the final stage of ovarian physiology and signifies the time when reproductive function is lost due to complete depletion of finite ovarian follicle supply.(2) It is defined as 12 months of amenorrhea and occurs at an average age of 51.3 years in the United States.(3) The process of menopause is directly related to ovarian aging, all aspects of the hypothalamic-pituitary-ovarian-uterine axis are altered with time. Estrogen withdrawal during the menopause transition (MT) is associated with alterations in the hypothalamic thermoregulatory neutral zone, a group of neurons that regulate body temperature.(2) This group of neurons, known as KNDy neurons for the co-expression of kisspeptin, neurokinin B (NKB), and dynorphin, are normally inhibited by estrogen are instead overstimulated during the MT and can cause dysregulation of body temperature. These changes lead to an increased frequency of bodily reaction to internal and environmental triggers that prevent heat loss. Vasomotor symptoms (VMS), also known as hot flashes, are known as the hallmark manifestations of the MT which include feelings of flushing, warmth sensation, skin reddening, and perspiration.(3) 

Symptoms of menopause are most common and severe in the first 1 to 2 years after the final menstrual period (FMP) and can continue for more than a decade for some women.(2) VMS affect as many as 80% of midlife women.(3) Moderate to severe VMS is defined as 7 or more episodes per day or 50-60 episodes per week.(1) Data show that women who experience frequent VMS (greater than 6 days in the previous 2 weeks) experience higher rates of anxiety, depression, difficulty sleeping and overall impaired quality of life.(4) Frequent VMS persisted on average 7.4 years and appear to be linked to cardiovascular, bone, and cognitive risks.(6) 

Hormone therapy (HT) remains the gold standard for relief of VMS and has been shown to prevent bone loss and fracture.(6) Women with significant sleep or mood disturbance during the MT may also benefit from HT. HT reduces symptom frequency by 90% as quickly as one month after initiation.(3) In the Women's Health Initiative (WHI), women with VMS experienced an 85% reduction in symptoms after treatment with estrogen plus progesterone.(2) Women 60 years of age or younger who are within 10 years of menopause onset and have no contraindications, the benefit-risk ratio is supportive for HT of bothersome VMS.(6) HT is considered safe and effective in low-risk women without underlying coronary heart disease or history of breast cancer.(2) The most common acute adverse effects of HT includes breast pain and uterine bleeding. HT has shown improvement in glycemic control and insulin resistance in women with and without type 2 diabetes, as well as other cardiovascular disease risk factors.(3) For women more than 10 years from the onset of menopause or 60 years or older who initiate HT, the benefit-risk ratio appears to be less favorable due to the greater absolute risks of coronary heart disease (CHD), stroke, venous thromboembolism (VTE), and dementia.(6) 

Estrogen regimens are available as estrogen-only, combined with progestin, or combined with a serum estrogen receptor modulator (SERM).(2) Systemic estrogens can be prescribed as oral drugs; transdermal patches, sprays and gels; or as vaginal rings. Meta-analysis of estrogen preparations found no evidence of a significant difference between transdermal and oral preparations for alleviating VMS. Estrogen-alone therapy (ET) can be used for symptomatic women without a uterus and estrogen plus progesterone therapy (EPT) or tissue-selective estrogen complex (TSEC) for women with a uterus to protect against endometrial neoplasia.(6) Vaginal formulations do not require progestin as these have not been shown to induce endometrial proliferation.(2)

Nonhormone options are important considerations for women who are not candidates for HT. Paroxetine 7.5 mg was the first nonhormonal drug FDA approved for the treatment of moderate to severe VMS, with improvements found in VMS severity and frequency for up to 24 months, along with improvements in sleep disruption, without weight gain or negative effects on libido. Other nonhormone medications that are recommended to reduce VMS include selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), gabapentin, and oxybutynin. Paroxetine, escitalopram, citalopram, venlafaxine, and desvenlafaxine and have been shown to significantly reduce VMS in large, double-blind, randomized, controlled trials (RCTs) of symptomatic women. Sertraline and fluoxetine trend towards improvement but were statistically insignificant and are not recommended. Duloxetine has been shown to reduce VMS in smaller studies. Hot flash reductions vary from 25% to 69% with these treatments, with improvement in hot flash severity and frequency from 27% to 61%. A pooled analysis from three RCTs showed that 10 mg to 20 mg of escitalopram, 0.5 mg of oral 17-beta-estradiol, and 75 mg of venlafaxine daily resulted in comparable reductions of VMS frequency. Gabapentin, an antiepileptic, has shown that it has improved the frequency and severity of VMS in several trials studying the dose of 900 mg/day. Gabapentin at higher doses (titrated to 2,400 mg/d) has been shown to be as beneficial as estrogen (conjugated equine estrogens 0.625 mg/d) in reducing hot flash scores. Oxybutynin, an antimuscarinic, demonstrated in one prospective study and two randomized double-blind studies, that doses ranging from 2.5 mg or 5 mg twice daily up to 15 mg extended-release daily, significantly improved moderate to severe VMS.(7)

Efficacy

The efficacy of Veozah for the treatment of moderate to severe VMS due to menopause was evaluated in the first 12-week, randomized, placebo-controlled, double-blind portion of each of the two phase 3 clinical trials. Women on placebo at 12-weeks were re-randomized to Veozah for a 40-week extension to evaluate safety for up to 52 weeks. A total of 522 women in Trial 1 (NCT04003155) and 500 women in Trial 2 (NCT04003142) who had a minimum average of 7 moderate to severe VMS per day were randomized to one of two doses of fezolinetant or placebo. The co-primary efficacy endpoints for both trials were the mean change from baseline in moderate to severe VMS frequency and severity to Weeks 4 and 12. Data from each trial showed statistically significant reduction from baseline in the frequency of moderate to severe VMS for Veozah 45 mg compared to placebo at Weeks 4 and 12. Both trials also demonstrated a statistically significant reduction from baseline in the severity of moderate to VMS at Weeks 4 and 12 for Veozah 45 mg compared to placebo.(1)

Safety

Veozah is contraindicated in women with any of the following conditions:(1)

• Known cirrhosis
• Severe renal impairment or end-stage renal disease
• Concomitant use with CYP1A2 inhibitors

Veozah has a boxed warning due to risks of hepatotoxicity.(1)

• Perform hepatic laboratory tests prior to initiation of treatment to evaluate for hepatic function and injury. Do not start Veozah if either aminotransferase is greater than or equal to 2 times the upper limit of normal (x ULN) or if the total bilirubin is greater than or equal to 2 x ULN for the evaluating laboratory.
• Perform follow-up hepatic laboratory testing monthly for the first 3 months, at 6 months, and 9 months of treatment
• Advise patients to discontinue Veozah immediately and seek medical attention including hepatic laboratory tests if they experience signs or symptoms that may suggest liver injury (new onset fatigue, decreased appetite, nausea, vomiting, pruritus, jaundice, pale feces, dark urine, or abdominal pain)
• Discontinue Veozah if transaminase elevations are greater than 5 x ULN, or if transaminase elevations are greater than 3 x ULN and the total bilirubin level is greater than 2 x ULN
• If transaminase elevations greater than 3 x ULN occur, perform more frequent follow-up hepatic laboratory tests until resolution
