Bone Histomorphometry Assessment For Dialysis Patients With Secondary Hyperparathyroidism of End Stage Renal Disease
The purpose of this study is to evaluate the effects of cinacalcet on markers of bone turnover in patients with kidney disease who are receiving dialysis.

Detailed Description
Secondary hyperparathyroidism (HPT) is common in people with end stage renal disease (kidney disease).
Patients with secondary HPT often have enlarged parathyroid glands in the neck and as a result often have elevated parathyroid hormone (PTH) levels .
Patients with secondary HPT may have bone disease (osteodystrophy).
Cinacalcet has been used to decrease PTH levels in patients with secondary HPT.
Patients with secondary HPT may have bone disease (osteodystrophy).
This bone disease may cause bone pain, fractures, and poor formation of red blood cells.
The purpose of this study is to evaluate effects of cinacalcet on markers of bone turnover in patients with kidney disease who are receiving dialysis.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Cinacalcet
All subjects were enrolled into the single arm to receive Cinacalcet.
There was no comparator arm.
|
All enrolled subjects receive study medication at a starting dose of 30 mg cinacalcet once daily beginning on day 1.
Possible sequential doses are 30 mg, 60mg, 90mg, 120mg, 180 mg taken once daily.
During the study, dose adjustment (dose increase/decrease/withholding) is based upon iPTH, serum calcium, and subject safety information.
Subjects swallowed tablets whole without biting or chewing.
Subjects were dispensed investigational product every 4 weeks starting from Day 1 through to Week 48.
