[Study Evaluating the Efficacy and Safety of a Digital Therapeutic as an Adjunct to TAU in Postpartum Depression]

Not Applicable

Terminated

Conditions: Postpartum Depression

Interventions: Device: ED001
Device: WB001

Registration Number: NCT05551195

Lead Sponsor: Woebot Health

Brief Summary: This study evaluates the efficacy of two digital therapeutics, WB001 and ED001, on depressive symptoms among women diagnosed with postpartum depression.

Detailed Description: This randomized, double-blind, controlled trial evaluates the efficacy and safety of 8 weeks of treatment of two digital therapeutics in a population of women with mild to moderate postpartum depression. Patients will be referred by an obstetrician, pediatrician, or other healthcare professional, or by other digital and site based recruitment methods and, if interested, will complete the pre-screening process. Those confirmed as eligible will be scheduled to attend a screening/baseline onsite visit. Eligible participants will be randomized to one of the two groups and will receive instructions on downloading and using the smartphone application to which they were randomized. Participants will use the app as instructed and will attend telehealth visits to complete assessments for the primary and safety endpoints at Weeks 4 and 8 (EOT).

Arm && Interventions

Group	Intervention	Description
Educational Control (ED001) with adjunctive Treatment as Usual	ED001	Participants randomized to the ED001 + TAU group will be asked to download and use the study application.
WB001 with adjunctive Treatment as Usual	WB001	Participants randomized to the WB001 + TAU group will be asked to download and use the study application.

Primary Outcome Measures

Name	Time	Method
Hamilton Rating Scale for Depression (HAM-D)	Change from Baseline to Post-treatment at Week 8	Measure of depression. This is a 6-item questionnaire, where total scores range from 0 to 22, with higher scores indicating greater severity of depression.

Secondary Outcome Measures

Name	Time	Method
Edinburgh Postpartum Depression Scale (EPDS)	Change Baseline to Post-treatment at Week 8	Measure of postpartum depression. A 10-item self-report questionnaire that assesses depression criteria and yields a total score from 0 to 30 where higher scores denote greater depression.
Patient Health Questionnaire (PHQ-9)	Change Baseline to Post-treatment at Week 8	Measure of depression. A 9-item self-report questionnaire where total scores range from 0 to 27, with higher scores indicating greater levels of depression
Generalized Anxiety Disorder Questionnaire (GAD-7)	Change from Baseline to Post-treatment at Week 8	Measure of anxiety. A 7-item brief self-report questionnaire, where total score range is between 0-21, with higher scores indicate greater levels of anxiety.
Mother-to-Infant Bonding Scale (MIBS)	Change from Baseline to Post-treatment at Week 8	Measure of mother-infant bond. An 8-item self-report questionnaire, where total scores range from 0 to 24, with lower scores indicating good bonding.
Clinical Global Impressions Scale - Severity of Illness (CGI-S)	Change Baseline to Post-treatment at Week 8	Measure of overall severity of current clinical presentation and symptomatology. A single item, 7-point Likert scale on which the investigator will rate patients' severity of illness based on clinical interviews and assessments relative to their experience with other patients with the same diagnosis. Responses include 0 (not assessed) and range from 1 (Normal, not at all ill) to 7 (Among the most extremely ill).
Clinical Global Impressions Scale - Global Improvement (CGI-I)	Change from Mid-treatment at Week 4 to Post-treatment at Week 8	Measure of improvement. A single item, 7-point Likert scale that assesses the overall improvement in patients' condition at the end of treatment. The investigator will rate whether the participant's total improvement was due entirely to the intervention. Responses include 0 (not assessed) and range from 1 (very much improved) to 7 (very much worse).
Patient Global Impression Scale (PGI)	PGI-S: Change from Baseline to Post-treatment at Week 8; PGI-C: Change from Mid-treatment at Week 4 to Post-treatment at Week 8	Measure of change in clinical status. A single item scale based on the CGI and adapted to the patient that mainly measures change in clinical status (PGI-C) but can also measure disease severity (PGI-S) or disease improvement (PGI-I). PGI-S responses for current illness severity range from "I Feel Fine (1)" to "I Feel Extremely Ill (4)". PGI-C responses range from "Very Much Improved (1) to "Very Much Worse (7)" since starting the trial. For both scales, lower scores indicate better outcomes.
Client Satisfaction Questionnaire (CSQ-8)	Post-treatment at Week 8	An 8-item measure used to assess client's satisfaction with treatment.Total scores range from 8-32, with high scores indicating greater satisfaction with the treatment.
