ClinicalTrials.gov Identifier:	NCT00381251

Purpose

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	Intervention	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 I

Study Type:	Interventional
Study Design:	Allocation: Non-Randomized Endpoint Classification: Bio-equivalence Study Intervention Model: Crossover Assignment Masking: Open Label Primary Purpose: Prevention
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.

Accepts Healthy Volunteers:	Yes

Criteria

Inclusion Criteria:

Healthy, postmenopausal women ages 35 to 70 years, inclusive.
Naturally postmenopausal women must not have had a menstrual period for at least six months, but less than 12 months, as confirmed by a blood test; or for at least 12 months with no blood hormone test confirmation. Naturally postmenopausal women must not have had a menstrual period since the age of 54. Surgically menopausal women must have undergone bilateral oophorectomy (removal of both ovaries) at least 5 months prior to the start of the study, and the surgical report may be requested to confirm the surgery date and that the surgery was not due to a cancerous condition.
Nonsmoker or smoker of fewer than 10 cigarettes per day as determined by history. Must be able to abstain from smoking during the inpatient stay.
