A Study of the Bioequivalence of 70 mg Alendronate and 70 mg Alendronate in Combination With 2800 IU Vitamin D

February 1, 2022 updated by: Organon and Co

A 2-Part, Open-Label, Randomized, Crossover Study to Evaluate the Bioequivalence of the 70 mg Alendronate/2800 IU Vitamin D3 Final Market Combination Tablet to a 70 mg Alendronate Marketed Tablet, and the Relative Bioavailability of Vitamin D3

This study will evaluate the bioequivalence of alendronate in combination with vitamin D (cholecalciferol) compared to alendronate alone and the bioequivalence of vitamin D in combination with alendronate compared to vitamin D alone.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sequence 1
alendronate/vitamin D combination then alendronate
Drug: alendronate sodium (+) cholecalciferol
A single dose tablet of 70 mg alendronate/2800 IU (international unit) vitamin D in one treatment period of each sequence. There will be a 12 day interval between each treatment period.
Drug: Comparator: alendronate
A single dose table of 70 mg alendronate in one treatment period of each sequence. There will be a 12 day interval between each treatment period.
Experimental: Sequence 2
alendronate then alendronate/vitamin D combination
Drug: alendronate sodium (+) cholecalciferol
A single dose tablet of 70 mg alendronate/2800 IU (international unit) vitamin D in one treatment period of each sequence. There will be a 12 day interval between each treatment period.
Drug: Comparator: alendronate
A single dose table of 70 mg alendronate in one treatment period of each sequence. There will be a 12 day interval between each treatment period.
Experimental: Sequence 3
alendronate/vitamin D combination then vitamin D
Drug: alendronate sodium (+) cholecalciferol
A single dose tablet of 70 mg alendronate/2800 IU (international unit) vitamin D in one treatment period of each sequence. There will be a 12 day interval between each treatment period.
Dietary supplement: Comparator: cholecalciferol (Vitamin D)
A single dose tablet of 2800 IU vitamin D in one treatment period of each sequence. There will be a 12 day interval between each treatment period.
Experimental: Sequence 4
vitamin D then alendronate/vitamin D combination

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Part 1: The Total Urinary Excretion of Alendronate With Alendronate/Vitamin D Combination Tablet Relative to Alendronate Tablet
Time Frame: 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.
On Day 1 across the 36-hour urinary collection period (Periods 1 and 2).
Part II : The Pharmacokinetic Parameters AUC0-120 hr of Vitamin D in Combination Tablet Relative to Vitamin D Tablet
Time Frame: 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.
On Day 1 across the 120-hour plasma collection period (Periods 1 and 2).
Part II : The Pharmacokinetic Parameters Cmax of Vitamin D in Combination Tablet Relative to Vitamin D Tablet
Time Frame: 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.
On Day 1 across the 120-hour plasma collection period (Periods 1 and 2).
