NCT01970345

Brief Summary

The proposed project will pilot the use of IGF-1 as a novel treatment for core symptoms of autism. We will use a double-blind, placebo-controlled crossover trial design in five children with autism to evaluate the impact of IGF-1 treatment on autism-specific impairments in socialization, language, and repetitive behaviors. We expect to provide evidence for the safety and feasibility of IGF-1 in ameliorating social withdrawal in children with Autistic Disorder. Further, we expect to demonstrate that IGF-1 is associated with improvement on secondary outcomes of social impairment, language delay, and repetitive behavior, as well as on functional outcomes of global severity.

Outcome Measures

Primary Outcomes (1)

  • Aberrant Behavior Checklist - Social Withdrawal Subscale

    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.

    Phase 1 - Week 4 and 12, Phase 2 - Week 4 and 8

Secondary Outcomes (9)

  • Social Pervasive Developmental Disorder-Behavior Inventory (PDDBI)

    Week 4 of Phase 1

  • Social Pervasive Developmental Disorder-Behavior Inventory (PDDBI)

    Week 12 of Phase 1

  • Social Pervasive Developmental Disorder-Behavior Inventory (PDDBI)

    Week 4 of Phase 2

  • Social Pervasive Developmental Disorder-Behavior Inventory (PDDBI)

    Week 8 of Phase 2

  • Repetitive Behavior

    Phase 1 - Week 4 and 12, Phase 2 - Week 4 and 8

  • +4 more secondary outcomes

Study Arms (2)

IGF-1

EXPERIMENTAL

Randomized, placebo-controlled, crossover format with 12 weeks in each treatment arm (IGF-1 and placebo), separated by a four-week wash-out phase. Dose titration will be 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 preprandial glucose monitoring will be performed by parents at treatment initiation, prior to each injection, and until a well tolerated dose is established.

Drug: Placebo/saline

Interventions

IGF-1DRUG

IGF-1 is an FDA-approved (IND exemption #113450), commercially available compound that crosses the blood-brain barrier and has beneficial effects on synaptic development by promoting neuronal cell survival, synaptic maturation, and synaptic plasticity.

Also known as: Increlex, mecasermin
