Trial Outcomes & Findings for A Study of Cinacalcet to Improve Achievement of National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI) Targets in Patients With End Stage Renal Disease (ESRD) (NCT NCT00431496)

NCT ID: NCT00431496

Last Updated: 2013-04-24

Results Overview

The National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF K/DOQI) recommends that treatment interventions to control parathyroid hormone should not result in significant elevation of calcium - phosphorus product (Ca x P; a derived value calculated from serum calcium and phosphorus levels). The primary objective of the study was to assess the simultaneous achievement of NKF K/DOQI targets of intact parathyroid hormone (iPTH) greater than or equal to 15.9 pmol/L and less than or equal to 31.8 pmol/L (150 - 300 pg/mL) and a Ca x P value \< 4.44 mmol\^2/L\^2 (55 mg\^2/dL\^2) during the effectiveness assessment phase.

Measure
Cinacalcet
Cinacalcet was administered orally at a starting dose of 30 mg/day for 23 weeks. Possible sequential doses during the study were 30, 60, 90, 120, and 180 mg. Dose escalation of cinacalcet occurred if the intact parathyroid hormone (iPTH) level from the previous study visit was \> 31.8 pmol/L (300 pg/mL), unless the participant had either reached the maximum dose (180 mg/day), the serum corrected total calcium was \< 2.1 mmol/L (8.4 mg/dL), or the participant experienced an adverse event that precluded a dose increase.
