Clinical Trial Summary

The main objective of this study is to evaluate the safety, efficacy and pharmacokinetics of paricalcitol oral solution in pediatric participants of ages 0 to 9 years with SHPT associated with stage 5 CKD receiving Peritoneal Dialysis (PD) or Hemodialysis (HD). The 24-week study is divided into two 12-week dosing periods (Dosing Period 1 followed by Dosing Period 2).

Eligibility

Inclusion Criteria:

• Participant is currently diagnosed with and/or being treated for secondary hyperparathyroidism (SHPT).
• Participant must be diagnosed with chronic kidney disease (CKD) stage 5 receiving peritoneal dialysis (PD) or hemodialysis (HD) for at least 30 days prior to initial Screening.
• For entry into the Washout Period (for vitamin D receptor activator [VDRA] non-naive participants), the participant must meet the appropriate laboratory criteria based upon the participant's age as described in the protocol.
• For entry into the Dosing Period (for VDRA-naive participants or VDRA non-naive participants who have completed the Washout Period), the participant must meet the appropriate laboratory criteria based upon the participant's age as described in the protocol.

Exclusion Criteria:

• Participant is scheduled to receive a living donor kidney transplant within 3 months of Screening or is a kidney transplant recipient.
• Participant is expected to discontinue peritoneal dialysis (PD) or hemodialysis (HD) within 3 months of the initial Screening visit.
• Participant has had a parathyroidectomy within 12 weeks prior to Screening.
• Participant is taking maintenance calcitonin, bisphosphonates, glucocorticoids (in a dose equivalent to more than > 0.16 mg/kg/day or 5 mg prednisone/day, whichever is lower), 4 weeks prior to Dosing.
• Participant is receiving calcimimetics at the time of Screening or is expected to initiate calcimimetics at any time throughout the study.
• Participant is unable to take oral medications.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Who Achieve Positive Response During Dosing Period 1	Positive response is defined as having two consecutive >= 30% reductions from baseline in intact parathyroid hormone (iPTH) or two consecutive iPTH values in the target range between 150 picograms (pg)/milliliters (mL) to 300 pg/mL (16.5-33.0 picomole[pmol]/L).
