Trial Outcomes & Findings for Optimization of the Dosage Regimen of Growth Hormone Therapy in Children Born Small for Gestational Age (NCT NCT00249821)

NCT ID: NCT00249821

Last Updated: 2017-09-26

Results Overview

Height Velocity (HV) is the change in height since the previous year´s measurement and more precisely: HV = {(h-hp)/(d-dp)} \* 365.25 \[centimeter (cm)/year\] where h is current height in cm, hp is previous height in cm, closest to 1 year previous, d is the current date and dp is the date of measurement of previous height, closest to 1 year previous. Additionally, d and dp have to be within 0.6 years and 1.5 years. HV is the mean height velocity over the interval between d and dp but is displayed as HV at d.

PRIMARY outcome

Timeframe: Month 12

Population: Full Analysis (FA) set included all the participants who received at least 1 dose of study medication and had at least 1 height evaluation post randomization. Last observation carried forward (LOCF) was used to impute missing values.

Height Velocity (HV) is the change in height since the previous year´s measurement and more precisely: HV = {(h-hp)/(d-dp)} \* 365.25 \[centimeter (cm)/year\] where h is current height in cm, hp is previous height in cm, closest to 1 year previous, d is the current date and dp is the date of measurement of previous height, closest to 1 year previous. Additionally, d and dp have to be within 0.6 years and 1.5 years. HV is the mean height velocity over the interval between d and dp but is displayed as HV at d.

SECONDARY outcome

Timeframe: Baseline (randomization), Month 6 and Month 12

Population: FA set included all the participants who received at least 1 dose of study medication and had at least 1 height evaluation post randomization. LOCF was used to impute missing values.

Height-Standard Deviation Score (H-SDS) was calculated as height minus mean (age-and sex-matched reference) divided by standard deviation (SD) \[age and sex-matched reference\]. Greater H-SDS indicates greater height.

Population: FA set included all the participants who received at least 1 dose of study medication and had at least 1 height evaluation post randomization. Here "n" signifies number of participants analyzed at that particular time point for each arm group respectively. LOCF was used to impute missing values.

Height Velocity-Standard Deviation Score (HV-SDS) was calculated as height velocity minus reference mean height velocity divided by SD of the reference mean height velocity. Greater HV-SDS indicates greater height velocity.
