  • Adult

Who may be able to join

  • Participant must be 18 to 60 years of age.

  • Participant must be willing to communicate with study staff via email.

Who cannot join

  • Participant with unstable and/or untreated conditions that may affect cognition, including untreated substance abuse/dependence disorders, unmanaged cardiovascular disease, endocrine or neurologic disorder, epilepsy, brain injury, hospitalization within 6-weeks of enrollment, ongoing chemotherapy or other cancer treatment (e.g., radiation) .

  • Participant has a history or current diagnosis of dementia and/or scores less than a 14 (75%) on the UBACC.
  • Participant with active suicidal ideations or behaviors within 2 months of screening.
  • Participant that shows signs of intoxication due to current substance abuse (including alcohol and/or illegal drugs) during any in person visit. Such participants will have that visit re-scheduled; participants with this problem occurring more than once may be excluded and dropped at the discretion of the Principal Investigators.
  • Participant has problems performing assessments or comprehending or following spoken instructions, or those with behaviors during screening or baseline visits that, in the judgment of the screening staff, are likely to present significant problems for the staff conducting assessments.
  • Participant is enrolled in a concurrent clinical trial involving an investigational pharmaceutical, nutraceutical, medical device, or behavioral treatment that could affect the outcome of this study. However, participation in standard treatments (e.g., occupational therapy) or use of prescribed medications (e.g., anti-depressants) is allowable..

About this study

Specific Aim 1: Finalize development of the closed-loop strategy in the MMT application.

Specific Aim 2: Evaluate the acceptability and feasibility of the MMT application with the target population to prepare for a large-scale efficacy trial.

Read the detailed description

Specific Aim 1: Investigators have recently constructed a beta version of the MMT application, comprised of the multi-modal assessment modules, several treatment modules and an initial version of the closed-loop algorithm to control treatment delivery. Utilizing the extensive experience in developing mobile assessment and treatment tools at Posit Science Corporation, the investigators will employ an iterative development process incorporating feedback from users (focus groups of patients with mood disorders), clinicians and scientists (project consultants) to achieve the following development goals: (1) Finalize MMT's closed-loop algorithm to incorporate all assessment modules and expand the existing triage approach; (2) Expand cognitive behavioral therapy (CBT) functions within the app; and (3) Expand in-app bi-directional communication feature between the clinician and user. At the completion of Specific Aim 1, the investigators will have a mobile app suitable for evaluation in a feasibility trial (Specific Aim 2).

Specific Aim 2: The investigators will conduct a single arm, open label feasibility field trial with 40 participants that meet criteria for Major Depressive Disorder (MDD). Participants will be asked to engage with the experimental cognitive treatment and spend up to six weeks engaged in 15 hours of cognitive training as an adjunct to their standard clinical treatment. The experimental cognitive treatment will be deployed as dictated by the closed loop predictive algorithm, with all patient data continuously accessible for remote monitoring by the attending clinicians, research staff and Principal Investigator at University of Minnesota, and research staff and Sponsor PI at Posit Science Corporation. Participants will be re-evaluated every two weeks during treatment use, and again at the expected time of completion of training, at 6 weeks, to evaluate changes in cognitive function. Participants will then stop using their assigned program for 6 weeks, and return for a follow-up assessment to evaluate the endurance of changes in cognitive function in the absence of further program use.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in total score for depressive symptoms using Beck Depression Scale (BDI-II)

    The Beck Depression Scale (BDI-II) is a self-report questionnaire that assesses depressive symptoms with a scoring range between 0-63.

    Measured: At 2 weeks, 4 weeks, 6 weeks and at 12 weeks

Secondary outcomes (4)
  1. Change in total score for depressive symptoms using Patient Health Questionnaire (PHQ-9)

    The Patient Health Questionnaire (PHQ-9) is a self-report questionnaire that assesses the degree of depression severity with a scoring range between 0-27.

    Measured: At 2 weeks, 4 weeks, 6 weeks and at 12 weeks

  2. Change in total score for anxiety symptoms using Generalized Anxiety Disorder (GAD-7)

    The Generalized Anxiety Disorder (GAD-7) is a self-reported questionnaire for screening and severity measuring of generalized anxiety disorder with a scoring range between 0-21.

    Measured: At 2 weeks, 4 weeks, 6 weeks and at 12 weeks

  3. Change in total score for mood symptoms using Immediate Mood Scaler (IMS)

    The Immediate Mood Scaler (IMS) is a clinical assessment that assesses momentary mood symptoms related to anxiety and depression with a scoring range between 22-181.

    Measured: At 2 weeks, 4 weeks, 6 weeks and at 12 weeks

  4. Change in total score for quality of life using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q)

    The Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) assesses the degree of enjoyment and satisfaction experienced in various areas of daily functioning with a scoring range between 0-70.

    Measured: At 2 weeks, 4 weeks, 6 weeks and at 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Mobile-device, plasticity-based adaptive cognitive treatment in people with Major Depressive Disorder, run by Posit Science Corporation at 1 site in United States.

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 7 inclusion and 8 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?

The record says: finished, as of the sponsor's last update on 5 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in total score for depressive symptoms using Beck Depression Scale (BDI-II) (time frame: At 2 weeks, 4 weeks, 6 weeks and at 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2023.
