This study will compare the bioequivalence of two new investigational combination formulations of Premarin and medroxyprogesterone acetate (MPA) with a currently marketed formulation of Premarin and medroxyprogesterone, Prempro™.
Prempro is indicated for use after menopause in women with a uterus to reduce moderate to severe hot flashes; to treat moderate to severe dryness, itching, and burning, in and around the vagina; and to help reduce your chances of getting osteoporosis (thin weak bones). The purpose of this study is to determine if these new formulations of Premarin and MPA provide the same levels of estrogen and MPA in the blood as Prempro in healthy postmenopausal women.
|Condition or disease||Intervention/treatment||Phase|
|Postmenopausal Osteoporosis Postmenopause||Drug: Formulations A and B of Premarin/MPA 0.45 mg/0.5 mg and PREMPRO0.45 mg/0.5 mg||Phase 1|
|Study Type :||Interventional (Clinical Trial)|
|Intervention Model:||Crossover Assignment|
|Masking:||None (Open Label)|
|Official Title:||An Open-Label, Single-Dose, Randomized, 3-Period, Crossover, Bioequivalence Study Between Two New Formulations of 0.45 mg/1.5 mg Premarin / Medroxyprogesterone Acetate (MPA) Compared With a Reference Formulation of 0.45mg/1.5mg Premarin / MPA (Prempro™) in Healthy Postmenopausal Women.|
|Study Start Date :||September 2006|
|Study Completion Date :||January 2007|
- Pharmacokinetic blood samples for unconjugated and total (unconjugated plus conjugated) estrogens and MPA will be obtained. The following pharmacokinetic parameters will be determined: Cmax, Tmax, t½, AUC0-T, AUC0-¥.
