Trial Outcomes & Findings for A Pilot Treatment Study of Insulin-Like Growth Factor-1 (IGF-1) in Autism Spectrum Disorder (NCT NCT01970345)

NCT ID: NCT01970345

Last Updated: 2024-02-08

Results Overview

Aberrant Behavior Checklist - Social Withdrawal Subscale has16 items, Each item is scored as 0 (never a problem), 1 (slight problem), 2 (moderately serious problem), or 3 (severe problem). Total Subscale scores range from 0 to 48. Higher score indicates poorer health outcomes.

IGF-1 Then Placebo
Randomized, placebo-controlled, crossover format with 12 weeks in each treatment arm (IGF-1 and placebo), separated by a four-week wash-out phase. IGF-1: Dose titration initiated at 0.04 mg/kg twice daily by subcutaneous injection, and increased, as tolerated, every week by 0.04 mg/kg per dose to a maximum of 0.12 mg/kg twice daily. Doses may be decreased according to tolerability by 0.04 mg/kg per dose. Medication will be administered twice daily with meals, and pre-prandial glucose monitoring will be performed by parents at treatment initiation, prior to each injection, and until a well-tolerated dose is established.

The Sensory, Ritual, Social Pragmatic, Semantic Pragmatic, Arouse, Specific Fears, and Aggressiveness subscales range from 0 to 100, where higher score indicates worse severity than the average child with autism. The Social Approach, Expressive, and Learning Memory subscales range from 0 to 100, where higher score indicates better skills relative to the average child with autism. Scores reported in subscales.

Clinician-rated interview designed to evaluate repetitive behavior in children with pervasive developmental disorders (PDDs). It is a modification of the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS), developed to assess typically-developing children with obsessive compulsive behavior. Because of language limitations in children with PDDs the CY-BOCS-PDD only includes the five compulsion items: Time Spent, Interference, Distress, Resistance of repetitive behavior, and Control of repetitive behavior. Each item is rated from 0 (none) through 4 (extreme), and scores can range from 0 to 20, with higher scores reflecting more severe symptoms. Usually a score 8 is considered clinically significant.

The CGI-S is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating. Full scale is 1 (normal, not at all ill) to 7 (extremely ill).

The Vineland Adaptive Behavior Scales, Second Edition (Survey Interview Form) yields an overall standard score (Adaptive Behavior Composite, ABC) and age standard scores in four domains. ABC scores have a mean of 100 and a standard deviation of 15 (range = 20 to 160). Higher scores suggest a higher level of adaptive functioning.
