Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Cinacalcet hydrochloride
Treatment: Drugs - Standard of Care

Experimental: Cinacalcet - Prior to the partial clinical hold, the starting dose was 0.25 mg/kg (based on dry weight) and was titrated upwards (maximum allowed daily dose of 4.2 mg/kg) based on plasma intact parathyroid hormone (iPTH), corrected serum calcium levels obtained monthly, and adverse signs and symptoms.
After the partial clinical hold the starting dose was 0.20 mg/kg (based on dry weight) and was titrated upwards (maximum allowed daily dose of 2.5 or 60 mg, whichever was lower) based on plasma iPTH, corrected serum calcium levels obtained monthly, weekly monitoring of ionized calcium levels, and adverse signs and symptoms.
All participants also received standard of care, which may have included vitamin D sterols.


Treatment: Drugs: Cinacalcet hydrochloride
Cinacalcet was provided as 5 mg capsules that were opened, and the contents were either sprinkled on soft food or suspended into a sucrose syrup to create a liquid suspension for administration. All doses were administered with food or shortly after a meal at the same time daily.

Treatment: Drugs: Standard of Care
Standard of care may have included vitamin D sterols (25 OH vitamin D and/or 1-25 OH vitamin D and its analogs) at the discretion of the investigator.

Eligibility
Key inclusion criteria
Inclusion criteria:

- Subjects between the ages of 28 days to < 6 years of age at enrollment (Czech Republic
minimum age is = 2 years of age at enrollment)

- Screening plasma iPTH level > 300 pg/mL (31.8 pmol/L) from the central laboratory, and
not have received any cinacalcet therapy for at least 30 days prior to start of dosing

- Screening corrected calcium from the central laboratory:

- = 9.4 mg/dL (2.35 mmol/L) if age 28 days to < 2 years

- = 8.8 (2.2 mmol/L) if age = 2 to < 6 years

- Serum phosphorus from the central laboratory:

- = 5.0 mg/dL (1.25 mmol/L) if age 28 days to < 1 year

- = 4.5 mg/dL (1.13 mmol/L) if age = 1 to < 6 years

- SHPT not due to vitamin D deficiency, per investigator assessment

Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criterion:

- History of congenital long QT syndrome, second or third degree heart block,
ventricular tachyarrhythmias or other conditions associated with prolonged QT interval

- Corrected QT interval (QTc) > 500 ms, using Bazett's formula

- QTc = 450 to = 500 ms, using Bazett's formula, unless written permission to enroll is
