Expanding the Observer-Reported Communication Ability (ORCA) Measure: Measuring the Communication Ability of Individuals With Rare, Neurodevelopmental Disorders

 

When assessing the communication ability of individuals with neurodevelopmental disorders (NDDs) in the context of clinical trials, existing clinical outcome assessments (COAs) have significant limitations, including the inability to differentiate among individuals and lack of input from parent advocates.

With a grant from the U.S. Food and Drug Administration (FDA), Dr. Christy Zigler (Principal Investigator) and other CHM investigators will work with COMBINEDBrain, a patient advocacy consortium, to expand the ORCA measure to a range of NDD populations. 

Expanded ORCA 

The project, Expanding the Observer-Reported Communication Ability (ORCA) Measure: Measuring the communication ability of individuals with rare, neurodevelopmental disorders, will use rigorous qualitative and quantitative methods to support the ORCA measure’s use with 13 other NDDs. The study team includes experts in:

  • COA development
  • Communication
  • Clinical trials
  • Neuropsychology

The team also includes a Stakeholder Engagement Group consisting of 16 leaders in the field including parents, patient advocates, and clinicians who will provide access to 13 distinct NDD populations. An External Technical Advisory Committee (ETAC) will provide additional guidance and will consist of:

  • Clinicians
  • Methodologists
  • Speech-language pathologists
  • Industry experts
  • Patient advocates
