ENRICO VERRINA, Istituto Giannina Gaslini
Twelve-month, multicenter, intra-subject controlled (retrospective-prospective), open-label, active-treatment study to evaluate the dose-response and pharmacokinetics (PK) of cinacalcet HCl for the treatment of Secondary Hyperparathyroidism (SHPT) in paediatric subjects with chronic kidney disease (CKD) on dialysis, followed by 12-month study extension.

Condition Intervention Phase
Secondary Hyperparathyroidism Drug: Cinacalcet HCl Phase 2 Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Twelve-month, Multicenter, Intra-subject Controlled (Retrospective-prospective), Open-label, Active-treatment Study to Evaluate the Efficacy, Safety, Tolerability and Pharmacokinetics (PK) of Cinacalcet Hydrochloride for the Treatment of Secondary Hyperparathyroidism (SHPT) in Paediatric Subjects With Chronic Kidney Disease (CKD) on Dialysis, Followed by 12-month Study Extension.

Primary Outcome Measures:
  • Composite EP, e.g. the proportion of patients who will have a reduction from baseline of >= 25% in mean iPTH levels with concomitant values for plasma P <6 mg/dL and Ca between 8.4 and 10.5 mg/dL or the Ca x P product <60 [ Time Frame: 6 months ]
    This composite EP will address the needed information on the appropriate dose of cinacalcet to be adopted in paediatric patients, and especially in younger children, as well as on the impact of treatment with calcimimetics on serum Ca and P levels, and on SHPT control over the long term

Secondary Outcome Measures:
  • The long term control of iPTH level < 300 pg/mL [ Time Frame: 18 months ]
  • The long term control of PTH, Ca, P, and the Ca x P product values [ Time Frame: 18 months ]
  • The PK/ PD ( iPTH and testosterone) profile at individual patient level [ Time Frame: 12 months ]
  • The long term auxological indices and patient growth velocity during cinacalcet treatment [ Time Frame: 18 months ]
  • The proportion of patients with treatment-emergent adverse events (AEs), serious AEs (SAEs), and laboratory abnormalities over long term [ Time Frame: 18 months ]

Estimated Enrollment: 30
Study Start Date: March 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: cinacalcet tab or extemporaneous solution po added to SoC

Subjects who meet all inclusion/exclusion criteria at baseline will be given cinacalcet 30mg film-coated tablet, for oral use added to phosphate binders and vitamin D analogue.

For subjects receiving a cinacalcet dose <30mg, commercially available cinacalcet 30mg tab will be ground and diluted with a 5% dextrose solution. Then, an aliquot of this solution corresponding to the individually prescribed dose will be administered as indicated.

Initial dosing of cinacalcet will be 0.5-0.75mg/kg or 30 mg po once daily (OD) each evening with food.

During the cinacalcet dose-titration 6-month period for efficacy assessment, the dose will be increased on monthly basis by 0.5 mg/kg or by 30mg OD to achieve the target iPTH value <180 pg/mL, as tolerated by the subject, up to maximum of 180mg OD in absence of signs of hypocalcemia, according to the current summary of product characteristics.

Drug: Cinacalcet HCl
The 6-month pre-treatment period will be followed by a run-in period with a baseline evaluation prior to the drug administration, followed by a 6-month cinacalcet dose titration period, during which the dose will be increased on monthly basis by 0.5 mg/kg or by 30 mg OD up to the achievement of target iPTH value <180 pg/mL as tolerated by the patient
Other Name: Mimpara®

Detailed Description:
This multicenter, intra-subject controlled, open-label, active-treatment study will assess in children affected by Secondary Hyperparathyroidism, aged 2-18 years on chronic dialysis not responsive to standard of care (SoC) therapy, the response after 6-month cinacalcet compared intra-subject to SoC alone at screening visit 6 months prior to cinacalcet start. Secondary objectives are to evaluate effects on growth over 18 months and PK profile. At baseline children have PTH levels>300 pg/mL, plasma P<6 mg/dL, and Ca 8.4-10.5 mg/dL, or Ca x P product>60 not responsive to SoC. Initial dosing of cinacalcet will be 0.5-0.75 mg/Kg per os OD to be adjusted up to a max of 180mg OD for target PTH values<180 pg/mL in absence of hypocalcemia. Thirty children will be enrolled at 12 centres participating in a national paediatric dialysis registry, corresponding to an α=0.05 and a power of 80% using the McNemar test, with an expected % of responders to cinacalcet or SoC of 40% or 5% respectively, with a drop-out rate of 15. Primary study endpoint (EP) will be the % of children who will have a reduction from baseline >25% in mean PTH levels during the 6-mo efficacy-assessment period. Among secondary EPs over 18 mos will be the % of patients with mean PTH levels<300 pg/mL; the % change in PTH, Ca, P values, and the Ca x P product; PK profile (or population profile by age) and its correlation with PTH and testosterone levels; auxological indices and growth velocity; % of children with treatment-emergent adverse events and lab abnormalities; retention on treatment and reasons of treatment withdrawal. The study will evaluate whether cinacalcet represents a safe and effective therapeutic option for SHPT children.
