About this study
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.
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.
Read the 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.

Cinacalcet HClDrug
Also called Mimpara®
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
| Study group | Role | What they receive |
|---|---|---|
| cinacalcet tab or extemporaneous solution po added to SoC | Experimental | 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. Receives: Drug: Cinacalcet HCl |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
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
Measured: 6 months
Secondary outcomes (5)
The long term control of iPTH level < 300 pg/mL
Measured: 18 months
The long term control of PTH, Ca, P, and the Ca x P product values
Measured: 18 months
The PK/ PD ( iPTH and testosterone) profile at individual patient level
Measured: 12 months
The long term auxological indices and patient growth velocity during cinacalcet treatment
Measured: 18 months
The proportion of patients with treatment-emergent adverse events (AEs), serious AEs (SAEs), and laboratory abnormalities over long term

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Cinacalcet HCl in people with Secondary Hyperparathyroidism, run by ENRICO VERRINA at 5 sites in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 11 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 24 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Enrico E. Verrina, MD (+390105636276, enricoverrina@ospedale-gaslini.ge.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
