Overview
Brief 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 Criteria
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.

Intervention: Paricalcitol
Outcomes
Primary Outcomes
Percentage of Participants Who Achieve Positive Response During Dosing Period 1
Time Frame: Up to Week 12
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).
Incidence of Hypercalcemia During Dosing Period 1
Time Frame: Up to Week 12
Incidence of hypercalcemia is defined as two consecutive, post-baseline, corrected calcium measurements above the normal participants's age-specific upper limit.
Secondary Outcomes
- Percentage of Participants Who Achieve a Positive Response During Dosing Periods 1 and 2 Combined(Up to Week 24)
- Percentage of Participants Who Achieve Two Consecutive >= 30% Reductions in iPTH From Baseline During Dosing Period 1(Up to Week 12)
- Percentage of Participants Who Achieve Two Consecutive iPTH Values Between 150 pg/mL to 300 pg/mL (16.5 - 33.0 pmol/L) During Dosing Period 1(Up to Week 12)
- Percentage of Participants Who Achieve a Positive Response During Dosing Period 2(Week 12 through Week 24)
- Percentage of Participants Who Achieve Two Consecutive >= 30% Reductions in iPTH From Baseline During Dosing Period 2(Week 12 through Week 24)
- Percentage of Participants Who Achieve Two Consecutive iPTH Values Between 150 pg/mL to 300 pg/mL (16.5 - 33.0 pmol/L) During Dosing Period 2(Week 12 through Week 24)
- Incidence of Hypercalcemia During Dosing Period 2(Week 12 through Week 24)
- Incidence of Hypercalcemia During Dosing Periods 1 and 2 Combined(Up to Week 24)
- Percentage of Participants Who Achieve Two Consecutive >= 30% Reductions in iPTH From Baseline During Dosing Periods 1 and 2 Combined(Up to Week 24)
- Percentage of Participants Who Achieve Two Consecutive iPTH Values Between 150 pg/mL to 300 pg/mL (16.5 - 33.0 pmol/L) During Dosing Periods 1 and 2 Combined(Up to Week 24)
