4-Week Study to Assess the Effect of Alendronate and Vitamin D3 Once Weekly on Fractional Calcium Absorption in Postmenopausal Osteoporotic Women (0217A-230)

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

To compare change in fractional calcium absorption following administration of MK0217A relative to matching placebo, in postmenopausal women with osteoporosis

Study Overview

• Status: Completed
• Conditions: Osteoporosis
• Intervention / Treatment: Drug: alendronate sodium (+) cholecalciferol; Drug: Comparator: Placebo (unspecified)

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: 2; Placebo	Drug: Comparator: Placebo (unspecified); MK0217A, Pbo tablet, once weekly for 4 weeks. All patients will be instructed to take the tablet fasting upon arising for the day with 6 to 8 oz. of plain water (i.e., tap), wait at least one-half hour while continuing to fast and before the first food, beverage (except water), or other medication. All patients must eat before lying down.
Experimental: 1; MK0217A	Drug: alendronate sodium (+) cholecalciferol; MK0217A, a tablet containing alendronate 70-mg and vitamin D3 2800 IU, once weekly for 4 weeks. All patients will be instructed to take the tablet fasting upon arising for the day with 6 to 8 oz. of plain water (i.e., tap), wait at least one-half hour while continuing to fast and before the first food, beverage (except water), or other medication. All patients must eat before lying down.; Other Names: MK0217A
