研究概览
简要总结
- 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
详细描述
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.

结局指标
主要结局
Change From Baseline in Annual Rate of Growth Standard Deviation Score (SDS) at Year 3
时间窗: Baseline, 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 Height
时间窗: Baseline, 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 3
时间窗: Baseline, 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 Height
时间窗: Baseline, 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 3
时间窗: Baseline, 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.
