A Study of an Investigational Medication for the Treatment of Secondary Hyperparathyroidism in Dialysis Patients - Full Text View

Sponsored by:	Amgen
Information provided by:	Amgen
ClinicalTrials.gov Identifier:	NCT00037635

Purpose

This 6 month long study will assess an investigational medication for patients on dialysis with secondary hyperparathyroidism. The study will look at the effects on parathyroid hormone, calcium and phosphorus levels.

Condition	Intervention	Phase
Secondary Hyperparathyroidism End Stage Renal Disease	Drug: AMG 073 Drug: Placebo	Phase III

MedlinePlus related topics: Kidney Failure

Drug Information available for: Cinacalcet Cinacalcet hydrochloride

U.S. FDA Resources

Study Type:	Interventional
Study Design:	Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator), Parallel Assignment, Safety/Efficacy Study
Official Title:	A Phase 3 Study to Assess the Efficacy and Safety of an Oral Calcimimetic Agent (AMG 073) in Secondary Hyperparathyroidism of End Stage Renal Disease Treated With Hemodialysis

Further study details as provided by Amgen:

Primary Outcome Measures:

To evaluate the efficacy of AMG 073 compared with placebo by determining the proportion of subjects with a mean intact parathyroid hormone (iPTH) value <= 250 pg/mL (26.5 pmol/L) during the efficacy assessment phase. [ Time Frame: efficacy assessment phase (last 14 weeks of treatment) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

To evaluate the efficacy of AMG 073 compared with placebo by determining: percentage change from baseline in mean calcium x phosphorus product (Ca x P) during the efficacy assessment phase [ Time Frame: efficacy assessment phase (last 14 weeks of treatment) ] [ Designated as safety issue: No ]
To evaluate the efficacy of AMG 073 compared with placebo by determining: changes in self-reported cognitive function from baseline to the end of the efficacy assessment phase [ Time Frame: efficacy assessment phase (last 14 weeks of treatment) ] [ Designated as safety issue: No ]
To evaluate the safety of AMG 073 compared with placebo. [ Time Frame: entire study ] [ Designated as safety issue: Yes ]
