Study summary

Psychological intervention by COBMINDEX application to reduce psychological stress among CD patients, fatigue and pain and improve the patients' well being, quality-of-life and disease-coping skills, as well as improvement of the patients' immunological profile and intestinal microbiome.

Read the detailed description

200 patients will be randomly divided into two groups - 100 patients will learn and practice COBMINDEX by a human therapist-social worker and 100 patients will learn and practice COBMINDEX by a digital therapist using the COBMINDEX application.

In the first 3-months there will be an assessment of patient progress following randomization to human therapist or digital therapist using the application for learning and practicing. During this period, the group of the human social-worker will have a limited access to the application dedicated for daily exercises and assessment.

In the following 9-month period, all patients will practice using the application, each group by it's permissions.

There will be daily assessment of stress, pain, fatigue, well-being and frequent assessments of patients' medical, psychological, and immunological status.

Throughout the trial, adverse events and concomitant medications will be collected.

Study arms

  • Experimental
    Intervention- COBMINDEX application

    The intervention in this arm is to learn during the first 3 months, cognitive, behavioral and mindfulness based stress reduction with daily exercise using a research dedicated application. Than, additional 9 months of practicing daily only with the application.

    Behavioral: COBMINDEX digital application

  • Active comparator
    Control- COBMINDEX with Human therapist

    The intervention in this arm is to learn during the first 3 months, cognitive, behavioral and mindfulness based stress reduction with daily exercise with human therapist, and than practicing daily only with the application.

    Behavioral: Human therapist (Control)

Interventions

  • BehavioralCOBMINDEX digital application

    COBMINDEX is a Cognitive, behavioral and mindfulness-based stress reduction with daily self-exercise. The intervention comprises of 7 sessions in which stress reduction techniques are learned. In this arm the Patient learns techniques and practices using digital application.

  • BehavioralHuman therapist (Control)

    COBMINDEX is a Cognitive, behavioral and mindfulness-based stress reduction with daily self-exercise. The intervention comprises of 7 sessions in which stress reduction techniques are learned. In this arm the Patient learns techniques from a human therapist (the comperator for learning from the application) and practices using digital application.

What researchers measure

Primary outcomes

  1. Effectiveness of application as compared to human therapist.

    Develop a smartphone application that will teach the patient COBMINDEX and to determine whether the application will be as effective as the psychological intervention delivered by the therapists. the primary end point is SIBDQ disease specific HRQOL. 10 questions each scale 1-7 with range 7-70. higher is better.

    Time frame: 12 months

Secondary outcomes

  1. Cost-effectiveness

    To determine the cost-effectiveness of the intervention as provided by application versus therapists by prospective monitoring of direct and indirect healthcare costs. A cost-effectiveness analysis to assess the value for money of the application versus therapist interventions will be performed using primary data collected from patients in the study. These data include information of utilization of healthcare services reported by patients. The cost of each service will be based on the Israel Ministry of Health List Price for health services. We will calculate indirect costs of lost productivity based on patient responses to the WPAI questionnaire. For each patient we will calculate the quality-adjusted life-year (QALY) based on responses to the SF-12 questionnaires

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Aug 2023 (actual). Primary completion is estimated for May 2027, 45 months after the start.

Of 288 non-industry interventional studies with no phase under Crohn Disease, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 67. This study's planned 45 months is close to that.

Counting every sponsor, half of 300 studies reached it within 45 months; a quarter within 21 and three quarters within 65.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 30, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
