February 28, 2024 updated by: David Beversdorf, University of Missouri-Columbia
The purpose of this study is to explore the effects of propranolol in combination with early intensive behavioral intervention on social interaction, and secondarily on language, anxiety, adaptive behaviors, and global function in children with autism in a double-blinded, placebo-controlled pilot trial.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The investigators' specific aim is to examine the effects of serial doses of propranolol in combination with early intensive behavioral intervention on social interaction, and secondarily on language tasks, anxiety, adaptive behaviors, and global function in children with autism in a double-blinded, placebo-controlled trial. The investigators will also examine whether response to treatment can be predicted based upon markers of autonomic functioning, such as pupillary light reflex and heart rate variability, and whether anxiety predicts treatment response. The investigators' hypothesis is that propranolol will augment the effects of behavioral therapy on social functioning and language abilities. The investigators have demonstrated benefits of propranolol on social functioning and language in previous single-dose studies in adults and adolescents with autism. The investigators also predict that those with the greatest degree of autonomic dysregulation will demonstrate the greatest benefit from the drug.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Propranolol arm
Propranolol will be administered in the form of a liquid dose via oral syringe by the participants' parent/caregiver an hour before each EIBI session. To minimize risk, the bodyweight adjusted minimum dose of propranolol used safely for test anxiety in healthy adults (10mg) will be used: participants weighing > 30 kg will be given 4 mg, participants weighing 22.5 - 30 kg will be given 3 mg, participants weighing 15 - 22.5 kg will be given 2 mg. Participants weighing < 15 kg will be excluded for safety reasons.
Drug: Propranolol
Participant will receive Propranolol prior to each EIBI session
Other Names:
  • Inderal
Placebo Comparator: Placebo arm
Placebo will be administered in the form of a liquid dose via oral syringe by the participants' parent/caregiver an hour before each EIBI session.The same bodyweight adjusted doses specified in the propranolol arm will be used for this arm.
Drug: Placebo
Participant will receive placebo prior to each EIBI session

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in General Social Outcome Measure (GSOM)
Time Frame: Week 12
The GSOM is a brief evaluation tool that measures a participant's level of social functioning and how it changes with intervention. There GSOM includes 4 different tasks: conversational reciprocity, ability to recognize facial expressions, social problem solving, affect demonstration, and emotional perspective taking. The experimenter administers each component of the GSOM to the participant and then scores their responses according to a pre-determined scoring rubric. Each component is scored on a 1-5 or 0 - 2 scale, with higher total scores indicating better social functioning. A video camera will be used to record the participant's behavior during GSOM administration for the purposes of having two independent raters score the tasks after the study session is complete. A camera will also be used during the affect demonstration task of the GSOM. The overall score is used. The range is 6-132, with higher scores being better.
Week 12
Change in Social Responsiveness Scale (SRS)
Time Frame: Week 12
This 65-item, parent-report measure asks questions about a participants' social awareness, social information processing, capacity for reciprocal social responses, social anxiety or avoidance, and characteristic autistic preoccupations or traits. The total score is used with a range of 0-195, with lower scores being better.
Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Preschool Anxiety Scale (PAS)
Time Frame: Week 12
To assess anxiety, the PAS will be completed by the parents/caregivers of participants. This self-report measure yields a total score in addition to six subscales (separation anxiety, social phobia, obsessive compulsive, panic/agoraphobia, physical injury fears, and generalized anxiety). The overall score is used. Range is 0-112 with lower score meaning less anxiety.
Week 12
Change in Aberrant Behavior Checklist (ABC)
Time Frame: Week 12
To assess overall behavioral disturbances, a parent/caregiver of the participants will complete ABC. This 58-item questionnaire is a well validated, reliable, and widely used assessment tool for interventions for a range of cognitive disorders. The full score is used, with a range of 0-174, with higher scores meaning more behaviors.
Week 12
Change in Vineland Adaptive Behavior Scales-II (VABS)
Time Frame: Week 12
To assess overall adaptive functioning, the VABS will be administered in the form of a structured interview with the parent/caregiver. The VABS is a well validated assessment used for the full range of our subjects' ages and yields standard scores in Communication, Daily Living Skills, Socialization, and Motor Skills. VABS scores for Socialization will be monitored in this study. The range is 20-160 with higher scores better.
Week 12
Change in Autism Impact Measure (AIM)
Time Frame: Week 12
The AIM will be administered to assess the frequency and impact of a participant's ASD-related symptoms. A parent/caregiver is asked a series of 41 questions regarding the frequency and the impact, or interference resulting from, a series of autism-associated behaviors. Peer interaction from the AIM is the primary domain obtained from this measure. For this domain the range is 0 to 40, with higher numbers more severe.
Week 12
Change in Preschool Language Scale (PLS):
Time Frame: Week 12
To evaluate language, we will administer the PLS, which has been developed for use in younger children (birth through age 7), and is appropriate for children of all ability levels, including nonverbal children. This play-based, interactive assessment is designed to assess receptive and expressive language skills and their change over time. The range is 50-150 with higher scores being better.
