Comparative Efficacy of Low-Dose Estradiol and Venlafaxine XR for Treatment of Menopausal Symptoms
Comparative Efficacy of Low-Dose Estradiol and the SNRI Venlafaxine XR for Treatment of Menopausal Symptoms

The primary objective of this study is to determine the efficacy of both low-dose oral (by mouth) 17-ß-estradiol and the non-hormonal drug venlafaxine XR compared to placebo in reducing hot flashes. Included in this objective is the intention to compare venlafaxine XR to estradiol therapy, to provide evidence of the relative efficacy of venlafaxine to what is currently considered the most established but also a controversial therapy. 17-ß-estradiol is a type of estrogen. Venlafaxine XR is the extended release (XR) version of venlafaxine. Venlafaxine XR is an serotonin-norepinephrine reuptake inhibitor (SNRI). A placebo is a substance containing no medication.

The MsFLASH-03 study (Menopausal Strategies: Finding Lasting Answers for Symptoms and Health - 03), Comparative Efficacy of Low-Dose Estradiol and the SNRI Venlafaxine XR for Treatment of Menopausal Symptoms, is a randomized, double-blind, placebo-controlled, three arm clinical trial. The design includes: 3 weeks of daily recording of hot flashes prior to drug treatment; 8 weeks of double-blind treatment with oral estradiol, venlafaxine, or placebo; followed by 14 days of drug taper for those on venlafaxine and 14 days of progesterone treatment for those on estradiol; followed by 2 weeks with no treatment for all groups; and a telephone follow-up post-treatment.

Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
  • Hot Flashes
  • Menopause
  • Vasomotor Disturbance
  • Drug: Low-dose 17-ß-estradiol
    Low-dose 17-ß-estradiol oral (by mouth), 0.5 mg once per day for 8 (eight) weeks. After the 8-week treatment, women with a uterus will receive medroxyprogesterone 10 mg once per day for 2 weeks (14 days). 17-ß-estradiol is approved by the US Food and Drug Administration (FDA) and is indicated for the treatment of menopausal symptoms. ß is the Greek symbol for beta; the symbol and the word are used interchangeably.
    Other Name: The brand name of estradiol being used in this study is Estrace®.
  • Drug: Venlafaxine XR
    Venlafaxine oral (by mouth) 37.5 mg once per day for 1 (one) week, then 75 mg once per day for 7 (seven) weeks. Venlafaxine XR should not be taken while also taking monoamine oxidase inhibitors (MAOIs). Venlafaxine XR is approved by the US Food and Drug Administration (FDA) for treatment of depression, generalized anxiety disorder, social anxiety disorder, and panic disorder, and is available by prescription. Venlafaxine XR is not FDA-approved for the treatment of hot flashes, although prior studies have indicated that it is useful for treating hot flashes and vasomotor symptoms. After the 8-week venlafaxine XR study treatment period, women will receive a tapering dose of venlafaxine XR 37.5 mg once per day for 14 days (2 weeks).
    Other Name: The brand name of venlafaxine XR that is being used in this study is Effexor XR®
  • Drug: Placebo
    The placebo is an inactive pill that looks like the active medication.
  • Active Comparator: Low-dose 17-ß-estradiol
    Intervention: Drug: Low-dose 17-ß-estradiol
  • Active Comparator: Venlafaxine XR
    Intervention: Drug: Venlafaxine XR
  • Placebo Comparator: Placebo
    Intervention: Drug: Placebo
