Osteoporosis | Randomized Study of Alendronate in Adult Patients With Cystic Fibrosis Related Osteoporosis

Osteoporosis research study

What is the primary objective of this study?

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.
