Medroxyprogesterone Compared With Venlafaxine in Treating Hot Flashes in Women
RATIONALE: Medroxyprogesterone and venlafaxine may be effective in relieving hot flashes. It is not yet known whether venlafaxine is more effective than medroxyprogesterone in relieving hot flashes.
PURPOSE: Randomized phase III trial to compare the effectiveness of medroxyprogesterone with that of venlafaxine in treating women who are experiencing hot flashes.
|Study Design:||Allocation: Randomized
Masking: Open Label
Primary Purpose: Supportive Care
|Official Title:||Phase III Comparison of Depomedroxyprogesterone Acetate (DPROV) to Venlafaxine for Managing Hot Flashes|
|Study Start Date:||April 2002|
- Compare the efficacy of medroxyprogesterone administered as 1 injection vs medroxyprogesterone administered as 3 injections (closed to accrual as of 1/22/03) vs venlafaxine for hot flash alleviation in women with symptomatic hot flashes.
- Compare the toxic effects of these regimens in these patients.
- Determine whether there is cross resistance between these 2 drugs in these patients.
- Compare the 1-year efficacy of these regimens in these patients.
OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to age (18 to 49 vs 50 and over), current tamoxifen use (yes vs no), current raloxifene use (yes vs no), duration of hot flash symptoms (less than 9 months vs 9 months or more), and average frequency of hot flashes per day (2-3 vs 4-9 vs 10 or more). Patients are randomized to 1 of 2 treatment arms. (Arm II closed to accrual as of 1/22/03.)
All patients complete a daily questionnaire regarding number of hot flashes beginning on day 1 and continuing for 7 weeks.
- Arm I: Patients receive oral venlafaxine once daily for 6 weeks beginning on day 8. After week 7, patients with satisfactory efficacy may continue venlafaxine for up to 6 months. Patients with unsatisfactory efficacy may cross over to arm III.
- Arm II (closed to accrual as of 1/22/03): Patients receive medroxyprogesterone intramuscularly (IM) on days 8, 22, and 36 for a total of 3 injections. After week 7, patients with unsatisfactory efficacy may cross over to arm I.
- Arm III: Patients receive medroxyprogesterone IM once on day 8. After week 7, patients with unsatisfactory efficacy may cross over to arm I.
Patients are followed at months 2, 3, 4, 5, 6, 8, 10, and 12.
PROJECTED ACCRUAL: A total of 220 patients (110 per treatment arm) will be accrued for this study within 18 months. (Arm II closed to accrual as of 1/22/03.)
