Randomized Study of Alendronate in Adult Patients With Cystic Fibrosis Related Osteoporosis
|ClinicalTrials.gov Identifier: NCT00004489|
Recruitment Status : Completed
First Posted : October 19, 1999
Last Update Posted : March 25, 2015
OBJECTIVES: I. Determine the bioavailability and biologic effect of alendronate on bone metabolism in patients with cystic fibrosis.
II. Assess the safety and efficacy of this treatment regimen in improving osteoporosis in this patient population.
|Condition or disease||Intervention/treatment||Phase|
|Osteoporosis Cystic Fibrosis||Drug: alendronate sodium Drug: calcium carbonate Drug: cholecalciferol||Not Applicable|
PROTOCOL OUTLINE: This is a randomized, double blind study. Patients will be stratified according to sex (male vs female) and osteoporosis disease severity (mild vs severe). Patients are randomized to one of two treatment arms.
Patients undergo bioavailability assessment to confirm the ability to absorb alendronate.
Arm I: Patients receive calcium and vitamin D supplements with a placebo daily for one month.
Arm II: Patients receive calcium and vitamin D supplements with oral alendronate daily for one month.
Treatment continues if differences are seen in bone mineral density between the treatment arms.
Patients are followed for biochemical response at week 6, 12, and 52. Bone mineral density is measured at 1 year and 2 years.
