Summary
To compare change in fractional calcium absorption following administration of MK0217A
relative to matching placebo, in postmenopausal women with osteoporosis
Clinical Details
Official title: A Double-Blind, Randomized, Placebo-Controlled, Multicenter 4-Week Study to Assess the Effect of Alendronate 70 mg and Vitamin D3 2800 IU Once Weekly on Fractional Calcium Absorption in Postmenopausal Osteoporotic Women
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
Primary outcome: To compare change in fractional calcium absorption following administration of MK0217A relative to matching placebo, in postmenopausal women with osteoporosis
Detailed description:
Placebo will be administered over a 4 week, single-blind run-in phase. Calcium, as
citrate-malate, will be administered throughout the study at an individualized dose
supplementing the patient's daily dietary calcium intake to a total of approximately 1200
mg. At the end of the stabilization period, baseline calcium absorption will be determined
and patients will be randomized to receive either MK0217A, or matching placebo once weekly
for 4 weeks.
