This is a pilot study to determine proof in principle that vilazodone, a selective serotonin reuptake inhibitor and 5HT1a agonist, reduces the frequency and severity of menopausal hot flashes relative to placebo. A secondary aim is to evaluate improvement in menopause-related quality of life.

Primary Outcome Measures:
  • Daily diary ratings of frequency and severity of hot flashes [ Time Frame: Change from baseline at Week 8 and post treatment -up. ] [ Designated as safety issue: No ]
    Hot flash frequency and severity will be recorded daily in the am and pm. 7-day averages will be used at baseline, week 4 and week 8.

Secondary Outcome Measures:
  • Percent of patients with >=50% reduction in moderate to severe hot flashes [ Time Frame: Percent change from baseline at Week 8 ] [ Designated as safety issue: No ]
    Frequency of hot flashes calculated from daily diaries

Other Outcome Measures:
  • Menopause-related quality of life (MENQOL) [ Time Frame: Change from baseline at Week 8 ] [ Designated as safety issue: No ]
    The MENQOL is a validated measure to assess the presence and bother of menopausal symptoms. This will be exploratory.

  • Adverse Symptoms Checklist [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: Yes ]
    A 17 item checklist of general adverse and withdrawal symptoms. It will be used at baseline and Week 12. Adverse events will be obtained by subject report at Week 4 and Week 8.

  • Patient Satisfaction Ratings [ Time Frame: Week 8 ] [ Designated as safety issue: Yes ]
    Patient global rating of satisfaction with medication.

  • Sheehan global ratings of symptom (hot flash)interference [ Time Frame: Change from Baseline at Week 8 ] [ Designated as safety issue: No ]
    Global ratings on a 10-point scale of the degree that symptoms interfere overall, with work, social activities and family life.

Arms Assigned Interventions
Experimental: experimental 1
vilazodone (viibryd). 20 mg or 40 mg/day for 8 weeks
Drug: vilazodone
capsules once/day for 8 weeks. Dose starts at 10 mg for 7 days, increases to 20 mg/day for 7 days, increases to 40 mg/day at week 3 of unimproved.
Other Name: viibryd
Placebo Comparator: placebo capsules (sugar pill)
Placebo capsules matched to the drug dose for 8 weeks
Drug: placebo capsules
placebo capsules matched to drug capsules.

Detailed Description:

This is a proposal to conduct a small clinical trial for proof in principle that vilazodone reduces the frequency and severity of menopausal hot flashes. An additional exploratory aim is to identify improvement in menopause-related quality of life. Healthy, perimenopausal women ages 45-60 with an average of 4 or more moderate or severe hot flashes/night sweats per day for 3 screening weeks will be randomized to 8 weeks of treatment in a 2:1 ratio of vilazodone or matching placebo pills. Flexible dosing of vilazodone will start at 10 mg once/day for 7 days, increase to 20 mg/day for 1 more week and increase to 40 mg once/day at week 3 if unimproved. The primary outcome assessments are the frequency and severity of hot flashes at week 4 and week 8 as assessed by prospective daily diaries (using 7-day mean scores from the daily diaries). The secondary outcome is clinical improvement, defined as hot flash frequency >=50% decrease from baseline. Treatment-emergent adverse events will be monitored and patient ratings of tolerability will be obtained.
