About this study
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
To compare change in fractional calcium absorption following administration of MK0217A relative to matching placebo, in postmenopausal women with osteoporosis
Read the 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.

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.
Comparator: Placebo (unspecified)Drug
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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing alendronate sodium (+) cholecalciferol in people with Osteoporosis, run by Organon and Co.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To compare change in fractional calcium absorption following administration of MK0217A relative to matching placebo, in postmenopausal women with osteoporosis (time frame: 4 Weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00641771, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2022.
