Safety and Efficacy of Hectorol in Pediatric Patients With Chronic Kidney Disease Stage 3 and 4 With Secondary Hyperparathyroidism Not Yet on Dialysis

An Open-Label, Randomized, Parallel Group Study to Assess the Safety and Efficacy of Hectorol® (Doxercalciferol Capsules) in Pediatric Patients With Chronic Kidney Disease Stages 3 and 4 With Secondary Hyperparathyroidism Not Yet on Dialysis

Primary Objective:

Evaluated the effect of Hectorol® capsules in reducing elevated levels of intact parathyroid hormone (iPTH).

Secondary Objectives:

• Evaluated the safety profile of Hectorol® capsules versus Rocaltrol® (calcitriol) capsules.
• Determined the pharmacokinetic profile of 1,25-dihydroxyvitamin D2 after administration of Hectorol®.

The total study duration per participant was approximately up to 28 weeks.

Inclusion criteria :

• Male or female aged 5 to 18 years old.
• Weight ≥15 kg.
• Chronic kidney disease (CKD) Stage 3 or 4 not on dialysis, defined as glomerular filtration rate (GFR) between 15 and 59 mL/min/1.73m^2 (established by Schwartz equation) at Week -2 visit.
• Intact parathyroid hormone (iPTH) value >100 pg/mL for CKD Stage 3 or >160 pg/mL for CKD Stage 4, at Week -2 visit.
• Signed informed consent/assent form.

Exclusion criteria:

• The participant had a serum 25-hydroxyvitamin D level <30 ng/mL at screening.
• The participant had a corrected calcium ≥10 mg/dL at the Week -2 visit.
• The participant had a serum phosphorus >4.5 mg/dL for children 13 to 18 years of age; >5.8 mg/dL for children 5 to 12 years of age at the Week -2 visit.
• The participant was anticipated to require maintenance hemodialysis within 3 months.
• The participant used cinacalcet or vitamin D sterol therapies such as calcitriol, doxercalciferol, or paricalcitol within 14 days prior to the baseline visit.
• The participant had a history of, or active, symptomatic heart disease within 12 months prior to the baseline (Week 0) visit.
• The participant had a chronic gastrointestinal disease (ie, malabsorption, severe chronic diarrhea, chronic ulcerative colitis, or ileostomy).
• The participant had primary hyperparathyroidism or has had a total parathyroidectomy.
• The participant had an active malignancy.
• The participant was unable to swallow a capsule in size similar to the Hectorol® and Rocaltrol® capsules.
• The participant had a history of sensitivity or allergy to doxercalciferol, calcitriol or other vitamin D analogs.
• The participant used aluminum or magnesium-based binders.
