About this study

Official title: Validation of EmoDTx as a Digital Endpoint for Mood Monitoring in Adult Patients With Unipolar Depression: An Observational Study Against Standard Depression Assessment Questionnaires

The aim of this study is to validate the EmoDTx as a digital tool for mood monitoring in adult patients with unipolar depression. The study is prospective, multicenter, and observational, with a single-arm approach. The device studied, EmoDTx, is a mood-monitoring application that analyzes patients' facial expressions to assess their emotional state. The study aims to compare mood scores obtained via EmoDTx with those of standard depression questionnaires (MADRS, PHQ-9, BDI-II, HAMD-17, QIDS-SR16). It will also provide information on how patients feel about the use of passive monitoring software (without the active involvement of the patient) and how the feedback sent to patients can help in their care.

Participants who agree to take part in the study, during a selection visit, will be able to:

  1. Install the software on a digital interface (smartphone, computer, etc.) and activate or deactivate it whenever they wish during the 8-week follow-up period.
  2. Attend scheduled appointments at the center (a first appointment, then a second 4 weeks later, and a final at 8 weeks) to complete a series of questionnaires, be questioned by the doctor, and fill in other questionnaires on their own.
  3. At home, answer questionnaires independently, 2 weeks and 6 weeks after the first appointment.
  4. The application's feedback will be deactivated during the first 4 weeks and then reactivated during the final 4 weeks.
  5. In parallel, an ancillary study will be conducted on 16 patients enrolled in EMC2FR who accepted and performed the video recording of their structured clinical interview following SCID-5-CV at baseline and 4 weeks.

    Measured: Between Baseline and 4 weeks, between Baseline and 8 weeks and between 4 weeks and 8 weeks

  5. Change of EmoDTx score

    Measured: between Baseline and 4 weeks - between Baseline and 8 weeks - between 4 weeks and 8 weeks

  6. Change of score QIDS- SR16 self administrated

    Measured: between Baseline and 4 weeks - between Baseline and 8 weeks - between 4 weeks and 8 weeks

    Measured: At 2-weeks and 6 weeks.

  12. Score QIDS-SR16 self administrated

    Measured: At 4-weeks and 8 weeks

  13. To evaluate the ability of EmoDTx to predict changes in patient's mood earlier than the standard-of-care questionnaires HAMD-17, within 4 weeks and 8 weeks of follow-up.

    Measured: Time to detection by EmoDTx of changes to depression severity symptoms within 4 weeks and 8 weeks of follow-up as compared to changes detected by standard-of-care questionnaires HAMD-17 Changes in depression severity

  14. To evaluate the ability of EmoDTx to predict changes in patient's mood earlier than the standard-of-care questionnaires MADRS, within 4 weeks and 8 weeks of follow-up.

Questions about this trial

What is this clinical trial studying?

An observational study of Unipolar Depression and Major Depressive Disorder (MDD), run by Emobot at 2 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?
