Official Title: “A Randomized, Open Label Study Evaluating the Effect on Renal Function of Intravenous Bonviva Given by Injection or Infusion, Compared With Oral Alendronate, in Postmenopausal Women With Osteoporosis at High Risk for Renal Disease.”

This 3 arm study will evaluate renal safety after administration of an intravenous injection or infusion of Bonviva, compared to oral alendronate, in patients with postmenopausal osteoporosis,at increased risk of renal disease. Patients will be randomized to receive Bonviva 3mg i.v. by a) injection or b)infusion once every 3 months, or alendronate 70mg p.o.

weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.
