Trial Outcomes & Findings for Endocrine Dysfunction and Growth Hormone Deficiency in Children With Optic Nerve Hypoplasia (NCT NCT00140413)

NCT ID: NCT00140413

Last Updated: 2015-04-01

Results Overview

Primary outcome measures included change in stature, weight, BMI, and weight-for-stature z-scores over the course of the study. Z-score indicates how many standard deviations an element is from the mean. It is calculated as z = (x - µ) σ, where µ is the mean of the population, and σ is the standard deviation of the population. A positive z-score indicates a datum above the mean, while a negative z-score indicates a datum below the mean. All z-scores were obtained using Epi Info ™ 3.5.4. (Centers for Disease Control, Atlanta, GA).

Participant Flow

Participants were recruited from an IRB-approved prospective optic nerve hypoplasia (ONH) registry study at Children's Hospital Los Angeles, between January 2005 through March 2011.

39 participants were screened for eligibility: 20 enrolled in the study; 6 failed to meet inclusion criteria; 9 declined participation; and 4 consented to participate but withdrew from the study prior to beginning any study procedures.

Measure
Treatment Group 1: Receiving Growth Hormone Treatment
Treatment group assignment was based on subject's stature SDS relative to the mid-parental target height (MPTH) at baseline and subsequent classification as growth deceleration or normal growth. Subjects with growth deceleration were assigned to the GH replacement treatment group in accordance with standard of care. Subjects with normal growth were randomized to treatment or to control (no intervention). The starting dose for GH replacement was calculated as 0.3 mg/kg/wk and subsequently modified based on observed length/height velocity and serum IGF-I levels.
Treatment Group 2: Control
Treatment group assignment was based on subject's stature SDS relative to the mid-parental target height (MPTH) at baseline and subsequent classification as growth deceleration or normal growth. Subjects with normal growth were randomized to treatment or to control. The control group received no intervention; however, control subjects were switched (crossed over) to the GH replacement group if, during the course of the study, they met criteria for growth deceleration.

Timeframe: Baseline and 36 months

Primary outcome measures included change in stature, weight, BMI, and weight-for-stature z-scores over the course of the study. Z-score indicates how many standard deviations an element is from the mean. It is calculated as z = (x - µ) σ, where µ is the mean of the population, and σ is the standard deviation of the population. A positive z-score indicates a datum above the mean, while a negative z-score indicates a datum below the mean. All z-scores were obtained using Epi Info ™ 3.5.4.

Measure
Treatment Group 1: Receiving Growth Hormone Treatment
n=10 Participants
Treatment group assignment was based on subject's stature SDS relative to the mid-parental target height (MPTH) at baseline and subsequent classification as growth deceleration or normal growth. Subjects with growth deceleration were assigned to the GH replacement treatment group in accordance with standard of care. Subjects with normal growth were randomized to treatment or to control (no intervention). The starting daily dose for GH replacement was calculated as 0.3 mg/kg/wk and subsequently modified based on observed length/height velocity and serum IGF-I levels.
Treatment Group 2: Control
n=4 Participants
Treatment group assignment was based on subject's stature SDS relative to the mid-parental target height (MPTH) at baseline and subsequent classification as growth deceleration or normal growth. Subjects with normal growth were randomized to treatment or to control. The control group received no intervention; however control subjects were switched (crossed over) to the GH replacement group if, during the course of the study, they met criteria for growth deceleration. A total of 7 subjects were randomized to the control group, 3 of whom were crossed over to treatment due to growth deceleration. Outcome measures for these 3 who crossed over were analyzed separately, under Treatment Group 3.
Treatment Group 3: Control Crossed Over to Treatment
n=3 Participants
3 control subjects were switched (crossed over) to the GH replacement group during the course of the study due to growth deceleration.
