NCT06982820

Brief Summary

The purpose of this research is to learn more about a new treatment for individuals with Major Depressive Disorder (MDD) with heightened symptoms of anhedonia (i.e. loss of pleasure or interest in activities). The treatment is called Prism, and it is a software device intended for a novel form of neurofeedback training to be used in a clinic setting. During this study, the subject will use different techniques to measure brain activities, including magnetic resonance imaging (MRI) and electroencephalography (EEG).

Outcome Measures

Primary Outcomes (1)

  • HDRS-21

    Hamilton Rating Scale for Depression - the maximum score is 64. A score above 20 is considered a severe depression.

    Change from baseline to week 12 (post training visit)

Secondary Outcomes (5)

  • SHAPS-C

    Change from baseline to week 12 (post-training visit)

  • HDRS-21

    Change from baseline to 3-month FU visit

  • CGI-I

    Change from baseline to week 12 (post-training visit)

  • CGI-I

    Change from week 12 to 3-Month follow-up Assessment

  • PHQ-9

    Change from baseline to week 12 (post-Training visit)

Study Arms (2)

Active arm

ACTIVE COMPARATOR

Participants randomized into the Active arm will receive reward system EEG-fMRI pattern (RS-EFP) Neuro Feedback (NF) Prism training as an adjunct to SOC.

Device: Prism Training

Sham arm

SHAM COMPARATOR

Participants randomized into the Sham arm will receive a Sham EFP-NF training with the same schedule as the active arm, adjunct to SOC.

Device: Prism Training

Interventions

Participants will complete 20 Prism training sessions. The Prism training sessions take place twice a week over a 10-week period, with a minimum of one night of sleep between sessions. Participants will also receive two single booster sessions, 4 weeks and 8 weeks after their last NF session completed.
