Study Endpoints

Primary Endpoints

To compare change in fractional calcium absorption following administration of MK0217A relative to matching placebo, in postmenopausal women with osteoporosis
4 Weeks
Part 1: The Total Urinary Excretion of Alendronate With Alendronate/Vitamin D Combination Tablet Relative to Alendronate Tablet
On Day 1 across the 36-hour urinary collection period (Periods 1 and 2).

Urinary excretion of alendronate was determined over a 36-hour period following single-dose administration of a 70 mg alendronate/2800-IU vitamin D3 combination tablet or 70 mg alendronate alone tablet. Urine for each treatment period was collected at -2 to 0 hours predose, 0 to 8, 8 to 24, and 24 to 36 hours postdose.

Part II : The Pharmacokinetic Parameters AUC0-120 hr of Vitamin D in Combination Tablet Relative to Vitamin D Tablet
On Day 1 across the 120-hour plasma collection period (Periods 1 and 2).

Serum vitamin D3 pharmacokinetic parameter AUC0-120 hr (area under the serum concentration-time curve) after treatment on Day 1was calculated following single-dose administration of a 70 mg alendronate/2800-IU vitamin D3 combination tablet or 2800-IU vitamin D3 tablet. Serum for each treatment period was collected at -24, -18, -12, -6, and 0 hours predose, and 2, 3, 5, 7, 9, 12, 16, 24, 36, 48, 72, 96, and 120 hours postdose.

Part II : The Pharmacokinetic Parameters Cmax of Vitamin D in Combination Tablet Relative to Vitamin D Tablet
On Day 1 across the 120-hour plasma collection period (Periods 1 and 2).

Serum vitamin D3 pharmacokinetic parameter Cmax (maximum concentration observed in serum) after treatmen on Day 1was calculated following single-dose administration of a 70 mg alendronate/2800-IU vitamin D3 combination tablet or 2800-IU vitamin D3 tablet. Serum for each treatment period was collected at -24, -18, -12, -6, and 0 hours predose, and 2, 3, 5, 7, 9, 12, 16, 24, 36, 48, 72, 96, and 120 hours postdose.

Frequently asked questions about alendronate cholecalciferol

What is alendronate cholecalciferol used for?

Alendronate cholecalciferol is used for osteoporosis. It is a small molecule being developed by Organon & Co. (OGN) and is currently in Phase 1 clinical development. The drug combines alendronate with vitamin D3 and is being studied in postmenopausal osteoporotic women and healthy volunteers.

What does alendronate cholecalciferol target?

Alendronate cholecalciferol targets bone metabolism through its alendronate component, a bisphosphonate that inhibits bone resorption, combined with cholecalciferol (vitamin D3) to support calcium absorption. The drug is being studied for its effect on fractional calcium absorption in postmenopausal osteoporotic women.

Who makes alendronate cholecalciferol?

Alendronate cholecalciferol is developed by Organon & Co., a pharmaceutical company traded under the ticker OGN. The drug is currently in Phase 1 clinical development for osteoporosis.

What phase is alendronate cholecalciferol in?

Alendronate cholecalciferol is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. Two Phase 1 trials have been completed, with a total enrollment of 300 participants.

What clinical trials is alendronate cholecalciferol in?

Alendronate cholecalciferol has two completed Phase 1 trials: NCT00641771, a 4-week study assessing the effect of alendronate and vitamin D3 once weekly on fractional calcium absorption in postmenopausal osteoporotic women (enrollment 56), and NCT00806416, a bioequivalence study of 70 mg alendronate alone versus in combination with 2800 IU vitamin D (enrollment 244).

Is alendronate cholecalciferol the same as alendronate with vitamin D?

Alendronate cholecalciferol is a combination of alendronate and cholecalciferol (vitamin D3). It is being studied as a once-weekly formulation for osteoporosis. The drug is distinct from alendronate alone, as it includes vitamin D3 to enhance calcium absorption.
