Prevention of Growth Retardation by Early Treatment With Growth Hormone (GH) in Children With CJA Treated by Corticosteroid Therapy

Phase 3
Terminated
Conditions
Endocrine System Diseases
Interventions
Registration Number
NCT00174291
Lead Sponsor
Pfizer
Brief Summary

* To evaluate the effect of increasing the growth hormone dose on the statural response

* To assess the value of early treatment during the course of arthritic disease by comparing the height acquired in the medium term by children in the two groups: treated from the start, or 1 year to 15 months after the diagnosis of CJA, or treated for 4 years after the diagnosis

Detailed Description

This trial terminated on 10-Jun-2011 due to prolonged issues with drug accountability and data collection discrepancies. The decision to terminate was not based on any safety concerns.

Primary Outcome Measures
NameTimeMethod
Change From Baseline in Annual Rate of Growth Standard Deviation Score (SDS) at Year 3Baseline, Year 3

Annual rate of growth SDS was obtained by measuring the annual growth rate, subtracting chronological age- and gender-appropriate mean annual growth rate and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.

Change From Baseline in Annual Rate of Growth Standard Deviation Score (SDS) at Final HeightBaseline, final height (assessed up to Year 9.5)

Annual rate of growth SDS was obtained by measuring the annual growth rate, subtracting chronological age- and gender-appropriate mean annual growth rate and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.

Change From Baseline in Height Standard Deviation Score (SDS) at Year 3Baseline, Year 3

Height was measured using a wall mounted device (example, Harpenden stadiometer). Height SDS was obtained by measuring the height, subtracting chronological age- and gender-appropriate mean height and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.

Change From Baseline in Height Standard Deviation Score (SDS) at Final HeightBaseline, final height (assessed up to Year 9.5)

Height was measured using a wall mounted device (example, Harpenden stadiometer). Height SDS was obtained by measuring the height, subtracting chronological age- and gender-appropriate mean height and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.

Change From Baseline in Predicted Height Standard Deviation Score (SDS) at Year 3Baseline, Year 3

Predicted height was calculated according to Greulich and Pyle using Bayley Pinneau method. Predicted height SDS was obtained by calculating the predicted height, subtracting chronological age- and gender-appropriate mean predicted height and dividing the result by standard deviation of that mean (as obtained from chronological age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.

Lean mass and fat mass: measurements of body composition assessed using Dual Energy X-ray Absorptiometry (DEXA) scan.

Bone mineralization, an estimate of the amount of mineral (such as calcium) in the bone, was assessed using DEXA scan.

Change From Baseline in Weight Standard Deviation Score (SDS) at Year 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5 and 9Baseline, Year 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9

Body weight was measured using a balance scale. Weight SDS was obtained by measuring the weight, subtracting age- and gender- appropriate mean weight and dividing the result by standard deviation of that mean (as obtained from age- and gender-specific population reference data). SDS indicated how many standard deviations higher (in case of positive SDS) or lower (in case of negative SDS) participant's value was relative to the mean of the reference population.
