Kintsugi Voice Device Pivotal Study

A prospective, single arm, non-randomized, pivotal clinical validation study to evaluate the ability of the Kintsugi Voice Device (the Device) to aid clinical assessment for depression by comparing its output with a diagnosis made by a clinician using the Structured Clinical Interview for DSM-5 (SCID-5-RV) for up to 1000 English speaking adult patients ages 22 and older living in the United States. Recruitment will occur for 1 year and participation will be for up to 2 weeks

Treatment and study plan

Kintsugi Voice Device

Device

The Kintsugi Voice Device is intended to be used to screen for the presence of voice signals consistent with a current moderate to severe depressive episode in patients aged 22 and older. The device is intended to be used by care providers licensed to screen for depression and in settings where the screening for depression occurs. The device is neither to be used in lieu of a complete patient evaluation nor to supplant any of the clinician's standard assessments for the screening or diagnosis of depression. The Kintsugi Voice Device is comprised of a software API and machine learning model that utilizes recorded voice samples as inputs and outputs the detection of signals consistent with current moderate to severe depressive episode as outputs.

Primary outcomes

  1. 1. Sensitivity and Specificity of Kintsugi Voice Device Relative to the SCID-5

    Time frame: Day 1

    Achieve a composite lower bound of sensitivity greater than or equal to 70% and specificity greater than or equal to 70% for the KV Device relative to the high diagnostic confidence clinical reference standard as defined in Section 7.4.1 for which the device provides a result

Secondary outcomes

  1. Adjudicated Samples Sensitivity and Specificity

    Time frame: Day 1

    Evaluate sensitivity and specificity for all adjudicated samples for which the device provides a result

  2. PPV and NPV Evaluation

    Time frame: Day 1

    Evaluate the Positive Predictive Value (PPV) and Negative Predictive Value (NPV)

  3. Subgroup Analysis (Sensitivity and Specificity)

    Time frame: Day 1

    Perform subgroup analyses including but not limited to age, race, and ethnicity

  4. Indeterminate Result Analysis

    Time frame: Day 1

    Measurement of the proportion of all participants for whom the device provides no result
