Etelcalcetide to Treat Secondary Hyperparathyroidism in Hemodialysis Patients With Chronic Kidney Disease-Mineral and Bone Disorder

February 27, 2017 updated by: KAI Pharmaceuticals

A Single-arm, Open-label, Multicenter, Dose Titration Study of KAI-4169 to Treat Secondary Hyperparathyroidism in Hemodialysis Subjects With Chronic Kidney Disease-Mineral and Bone Disorder

The purpose of this study is to evaluate the effect of thrice weekly intravenous (IV) administration of etelcalcetide in the treatment of secondary hyperparathyroidism (SHPT) in hemodialysis patients with chronic kidney disease-mineral and bone disorder (CKD-MBD).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Etelcalcetide
Participants received etelcalcetide three times a week (TIW) administered by intravenous bolus injection at the end of each hemodialysis session for 12 weeks. The starting dose was 5 mg and may have been titrated every 4 weeks based on the preceding serum parathyroid hormone (PTH) and corrected calcium (cCa) levels to a maximum dose of 20 mg per hemodialysis session in order to achieve the targeted PTH range while maintaining serum calcium within an acceptable range.
Drug: Etelcalcetide
Administered 3 times a week by bolus injection into the venous line of the dialysis circuit after the end of hemodialysis.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline in Parathyroid Hormone (PTH) During the Efficacy Period
Time Frame: Baseline and the efficacy period, defined as from 14 days prior to and 3 days after the last dose of study drug (approximately days 68 - 85 for participants who completed 12 weeks of treatment)
Baseline was defined as the average of 3 predialysis PTH results obtained within 3 weeks of and prior to the first dose of study drug. The efficacy period (defined as the period from 14 days prior to and 3 days after the last dose of study drug) value was the mean of the prehemodialysis values obtained during that period.
Baseline and the efficacy period, defined as from 14 days prior to and 3 days after the last dose of study drug (approximately days 68 - 85 for participants who completed 12 weeks of treatment)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With ≥ 30% Reduction in PTH From Baseline During the Efficacy Period
Time Frame: Baseline and the efficacy period, defined as from 14 days prior to and 3 days after the last dose of study drug (approximately days 68 - 85 for participants who completed 12 weeks of treatment)
The efficacy period (defined as the period from 14 days prior to and 3 days after the last dose of study drug) value was the mean of the prehemodialysis values obtained during that period.
Baseline and the efficacy period, defined as from 14 days prior to and 3 days after the last dose of study drug (approximately days 68 - 85 for participants who completed 12 weeks of treatment)
Percentage of Participants With PTH ≤ 300 pg/mL During the Efficacy Period
Time Frame: The efficacy period, defined as from 14 days prior to and 3 days after the last dose of study drug (approximately days 68 - 85 for participants who completed 12 weeks of treatment)
The efficacy period (defined as the period from 14 days prior to and 3 days after the last dose of study drug) value was the mean of the prehemodialysis values obtained during that period.
