Placebo Versus SBR759 in Lowering Phosphate in Dialysis Patients (SBR759)

This study has been completed.
Information provided by:
Novartis Identifier:
First received: February 15, 2010
Last updated: July 20, 2011
Last verified: July 2011
This study will compare placebo to 4 different doses of SBR759 to assess the phosphate lowering efficacy in dialysis patients.

Condition Intervention Phase
Hyperphosphatemia Chronic Kidney Disease Drug: SBR759A Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Placebo-controlled Multi-center Trial to Compare the Phosphate Lowering Efficacy of Different Doses of SBR759 to Placebo

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Evaluate the change from baseline in 72-hour serum phosphate levels of 4 different doses of SBR759 versus placebo over 4 weeks of treatment [ Time Frame: 6 weeks ]

Secondary Outcome Measures:
  • Evaluate changes in serum phosphate during a 2 week random treatment withdrawal period of SBR759 after 4 weeks treatment [ Time Frame: 6 weeks ]
  • Evaluate dose-dependent efficacy of SBR759 [ Time Frame: 6 weeks ]
  • Compare the short-term safety profile and dose-dependent tolerability of SBR759 dosed with meals taken 3 times a day to that of placebo [ Time Frame: 6 weeks ]

Enrollment: 115
Study Start Date: February 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
