Trial Outcomes & Findings for Study to Evaluate Cinacalcet in Children With Chronic Kidney Disease (NCT NCT01290029)

NCT ID: NCT01290029

Last Updated: 2020-06-17

Results Overview

A serious adverse event is defined as an adverse event that meets at least 1 of the following serious criteria: • fatal • life threatening • requires in patient hospitalization or prolongation of existing hospitalization • results in persistent or significant disability/incapacity • congenital anomaly/birth defect • other medically important serious event. Treatment-related adverse events are those the investigator assessed as being possibly related to any study mandated activity (eg, administration of investigational product, protocol-required therapies, device(s) and/or procedure). Events of interest included acute pancreatitis, convulsions, drug related hepatic disorders, fractures, hypersensitivity, hypocalcemia, ischaemic heart disease, ventricular tachyarrhythmias, cardiac failure, and hypotension.

Participant Flow

The study was conducted at 7 study centers in Belgium (1 site), Germany (1 site), the United Kingdom (2 sites), and the United States (3 sites). The first participant was enrolled 25 January 2011 and the last participant on 25 August 2015.

Due to blood volume collection limitations in children, participants were randomized in a 1:1 ratio to one of the following 2 pharmacodynamic (PD) sampling sequences: 2, 8, and 48 hours postdose; or 2, 12, and 48 hours postdose.
