Outcome Measures

Primary Outcomes (1)

  • Change From Baseline to Week 6 in the MADRS Total Score

    The MADRS is used to assess depressive symptom severity. It consists of 10 items (apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts and suicidal thoughts), each rated from 0 to 6 with zero being the "best" rating and 6 being the "worst" rating. The MADRS total score is the sum of ratings for all 10 items. The total score ranges from 0 to 60. A higher score on the MADRS represents a more severe level of depression. A negative change from baseline indicates improvement. Least square (LS) mean was estimated using Mixed Model Repeated Measures (MMRM) method.

    Baseline (Day 1) to Week 6

Secondary Outcomes (1)

  • Change From Baseline to Week 6 in the GAD-7 Total Score

    Baseline (Day 1) to Week 6

Other Outcomes (8)

  • Change From Baseline to Weeks 2 and 4 in the MADRS Total Score

    Baseline (Day 1) to Weeks 2 and 4

  • Change From Baseline to Weeks 2 and 4 in the GAD-7 Total Score

    Baseline (Day 1) to Weeks 2 and 4

  • MADRS Response Rate at Weeks 2, 4, and 6

Study Arms (2)

Digital Therapeutic A - CT-152

OTHER

Participants received digital treatment session by using the CT-152 mobile application (app) from Day 1 up to Week 6 of the treatment period. Each treatment session consisted of Emotional Faces Memory Task (EFMT) exercises and a psychotherapy lesson. From Week 7 up to Week 10 participants continued using the CT-152 app with optional psychotherapy lesson but did not receive any new EFMT exercises during this period. Participants continued receiving brief SMS messages during Weeks 7 to 10 as a reminder of the previously completed CT-152 treatment courses.

Device: CT-152 - Digital Therapeutic

Digital Therapeutic B - Sham

OTHER

Participants received digital treatment session by using a sham mobile app from Day 1 up to Week 6 of the treatment period. Each treatment session consisted of a Shape and Memory Task (SMT) exercise only. From Week 7 up to Week 10 participants continued using the sham app but did not receive any new SMT exercises during this period. Participants continued receiving brief SMS messages during Weeks 7 to 10 as a reminder of the previously completed sham treatment courses.

Device: Sham
