Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sequence 1

alendronate/vitamin D combination then alendronate

Group Type EXPERIMENTAL

alendronate sodium (+) cholecalciferol

Intervention Type DRUG

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.

Comparator: alendronate

Intervention Type DRUG

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.

Sequence 2

alendronate then alendronate/vitamin D combination

Group Type EXPERIMENTAL

alendronate sodium (+) cholecalciferol

Intervention Type DRUG

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.

Comparator: alendronate

Intervention Type DRUG

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.

Sequence 3

alendronate/vitamin D combination then vitamin D

Group Type EXPERIMENTAL

alendronate sodium (+) cholecalciferol

Intervention Type DRUG

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.

Comparator: cholecalciferol (Vitamin D)

Intervention Type DIETARY_SUPPLEMENT

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.

Sequence 4
