Clinical Trial Summary

This study is a pragmatic clinical trial examining the comparative effectiveness of two stimulant medications (methylphenidate and amphetamine) in the treatment of ADHD in children and adolescents with autism. Using a sequential, multiple assignment randomization trial (SMART) design the study will not only assess these two medications but also the role of an increasingly popular class of ADHD medication, the alpha-2 agonists. Findings from this study will help improve clinicians' approach to medication selection and reduce the repeated trials of multiple medications that are current standard care.

Description:

Current data shows that 1 in 54 children in the United States are diagnosed with autism spectrum disorder (ASD). Additional data shows that those diagnosed with autism are also at risk for being diagnosed with a co-occurring condition such as attention deficit/hyperactivity disorder (ADHD). Managing the symptoms of each can be challenging for providers, patients, and parents.

Patients with ASD who are diagnosed with ADHD often face the challenge of finding the best medication options to treat symptoms. It is known that children with ASD and ADHD frequently respond differently to these treatments than typically developing (TD) children. Currently, no clear recommendations exist for parents or providers to follow to guide best medication options for patients with ASD and ADHD. This lack of medication knowledge and suboptimal medication management can lead to poor results and have substantial negative life impact for patients and their families.

The main goal of this study is to determine if the most prescribed medications for ADHD in TD children are similarly effective for patients who also have a diagnosis of autism. The results of this study will improve provider understanding of first-line stimulant medicines, methylphenidate and amphetamine compound, with ASD patients. Parents will determine medication effectiveness through discussion with their child and with their doctor as well as their own observations and will drive the medication adjustment process. Parents will provide ratings of effectiveness using the Clinical Global Impression measure every two weeks and the Aberrant Behavior Checklist and the Vanderbilt Parent Rating Scale will be completed monthly. For those patients who do not respond to first-line medicines, this study will further develop the understanding of second-line medication options, the alpha2 agonists guanfacine and clonidine. Parents will provide ratings using the same measures as before. Additional study measures will collect and review parent/caregiver input in the process of determining medication continuation. Most measures will be completed through electronic portals, reducing the need for families to come to the hospital to participate in this study.

While these medications are routinely prescribed to treat ADHD in children and adolescents with ASD, their relative effectiveness is not known. Randomizing participants to these different medicines in this format, called a SMART (Sequential Multiple Assignment Randomization Trial) design, will provide data on how well these medications work in children with ASD and ADHD, how they work compared to each other, and how their side effects differ from use in TD children. This study will also examine the effect of these medicines on target problems identified by parents, such as oppositional behavior. Parents/caregivers will be a significant part of the data and input captured to determine if medication should continue or be discontinued. The care team of patient, parent, and provider is solid in this project and will lead to optimal decision pathways for future patients with autism.

The aims outlined in this study are beneficial to patients with autism and their families/caregivers who often help navigate health care with them for life. Having access to evidence-based best practices when making medication decisions can impact and expedite positive outcomes in managing the symptoms of ADHD. When symptoms are managed at optimal levels, patients can focus on building life skills and accessing opportunities toward meaningful life outcomes.

Coproduced with parents and providers, this study is designed to reduce the trial and error aspect of prescribing ADHD medications and build provider and parent knowledge in best practice. The patient and family voice are an integral part of the study design process. This coproduction of treatment evidence helps ensure best outcomes for the patient and is supported by the inclusion of stakeholders. Participants will be children 4 to 17 years of age recruited from The Autism Care Network, the first and only network of its kind focused on better autism care, delivered at scale and at speed, to improve health and quality of life for children with autism and their families throughout North America. Twelve of the 20 network sites will participate in this study, each with providers and patients' parents committed to ensuring more than 500 patients will be part of this study and who are also committed to continuously improving whole-person and whole-family autism care.

7. Patient must have a consistent reporter (e.g., parent) who spends regular time with the child.

8. Patient can be on other psychotropic medications (selective serotonin reuptake inhibitor (SSRI), atypical antipsychotic, anticonvulsant) if dose has been stable for > 4 weeks prior to consent with no plans for a dose change during the study.

9. Patient with prior trial of ADHD medication more than one year before enrollment, based on clinician judgement of reason for prior trial failure.
