Details and patient eligibility

About

This study is a large-scale pivotal clinical validation of the AI-COA® software device. The purpose is to confirm the tool's accuracy and performance across a demographically diverse population of adults with Major Depressive Disorder (MDD), ensuring it functions fairly and reliably across different subgroups.

Full description

The SEQUOIA-3 study is a Comprehensive U.S. Clinical Validation of the AI-generated Clinical Outcome Assessment (AI-COA®) for depression and anxiety. This observational study supports the clinical validation of a digital tool intended to measure depression severity using audiovisual data from clinical interviews. The study builds on previous research to establish the tool's validity for regulatory qualification.

Key elements of the study include:

Diverse Enrollment: The study will prospectively enroll a large, stratified sample to ensure adequate representation across sex, race, and ethnicity, as well as a full range of symptom severity (from remission to severe).

Validation: The software's severity scores will be compared against a "ground truth" standard derived from the consensus of independent human raters.

Remote Assessment: Participants will complete standard clinical interviews and self-report measures via secure video conferencing.

The results will be used to demonstrate the tool's generalizability and its ability to provide unbiased assessments across different patient populations.

Enrollment: 650 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

  • Receiving any fast-acting treatment for depression or anxiety (e.g. ketamine, psychedelics, deep brain stimulation, etc.) in between initial baseline assessment (A1) and Restest (A2) , or in between Follow up assessment (B1) and Retest (B2)
  • Anxiolytics: Use of benzodiazepines or other anxiety-reducing medications that could affect speech or motor activity, within the past 4 weeks.
  • Antipsychotics and Mood Stabilizers: Medications that can alter cognitive and motor functions, within the past 6 weeks.
  • Stimulants: Use of medications like methylphenidate or amphetamines that affect energy levels and behavior, within the past 2 weeks
  • Epilepsy medication: seizure activity or medication side effects that may alter behavior, within the past 4 weeks.

• Any history or evidence of any of the following conditions:

  • Neurodevelopmental, Neurocognitive, Neurodegenerative or movement disorders including, but not limited to:
