A Study of Bonviva (Ibandronate) and Alendronate on Renal Function in Postmenopausal Women With Osteoporosis at High Risk for Renal Disease. - Full Text View

Sponsor:	Hoffmann-La Roche
Information provided by:	Hoffmann-La Roche
ClinicalTrials.gov Identifier:	NCT00503113

Purpose

This 3 arm study will evaluate renal safety after administration of an intravenous (iv) 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 intravenous (iv) by a) injection or b) infusion once every 3 months, or alendronate 70mg per oral (po) weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is 500+ individuals.

Primary Outcome Measures:

Absolute Change From Baseline in Actual Glomerular Filtration Rate (GFR) (Using Abbreviated Modification of Diet in Renal Disease [MDRD] Formula) [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
The primary parameter of the study was the change (mL/min) from baseline in actual GFR (abbreviated MDRD formula using the patients' actual body surface area) after 9 months (or 40 weeks) of treatment.

Secondary Outcome Measures:

Absolute Change From Baseline in Actual GFR (Using Cockcroft-Gault [CG] Formula) [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
Change (mL/min) from baseline in actual GFR (using Cockcroft-Gault [CG] formula) after 9 months (or 40 weeks) of treatment.
Relative Change From Baseline in Actual GFR (Using Abbreviated MDRD Formula) [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
Change (mL/min) from baseline in actual GFR (abbreviated MDRD formula using the patient's actual body surface area) after 9 months (or 40 weeks) of treatment.
Relative Change From Baseline in Actual GFR (Using CG Formula) [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
Change (mL/min) from baseline in actual GFR (CG formula using the patient's actual body surface area) after 9 months (or 40 weeks) of treatment.
Absolute Change From Baseline in Mean Serum Creatinine. [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
Relative Change From Baseline in Mean Serum Creatinine. [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
Absolute Change From Baseline in Urine Albumin-to-Creatinine Ratio. [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
Relative Change From Baseline in Urine Albumin-to-Creatinine Ratio. [ Time Frame: Baseline and 9 months ] [ Designated as safety issue: Yes ]
The relative change from baseline in this case is positively skewed (while the absolute change is not) and the means tends to more positive values.
