Smart Symptom Tracking ALEX Application for Tracking and Monitoring Gastrointestinal Health, Smart Horizons Pilot Trial

June 3, 2026 updated by: Mayo Clinic

Smart Horizons Pilot: A Feasibility and Outcomes Evaluation of Digital Symptom Tracking for Gastrointestinal Health

This clinical trial compares the impact of the Smart Symptom Tracking ALEX application (app) to standard symptom-tracking practices in tracking and monitoring gastrointestinal (GI) symptoms in young adults. Rates of early-onset colorectal cancer are rising sharply and it is projected to become the leading cause of cancer-related death in young adults. Despite this, adults under 45 still face barriers to diagnosis, including access to screening, unclear guidance on the impact of GI symptoms and dismissal of symptoms by healthcare providers. Current screening guidelines lack guidance on monitoring early symptoms in younger adults. The Smart Symptom Tracking ALEX tool is a digital platform that uses artificial intelligence to provide prompts for symptoms, coaching, reminders and education. Standard of care clinical practices include paper-based logs to report symptoms. Using the Smart Symptom Tracking ALEX app may provide more detailed symptom reports and increase self-reported symptom communication compared to standard symptom-tracking practices in young adults concerned about their GI health.

Enrollment (Estimated)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Ages 18-44 years
  • Concerned about their GI health
  • Able to speak and read English
  • Willing to complete a four-week symptom tracking protocol

Exclusion Criteria:

  • Unable to understand the informed consent or comply with protocol requirements

Study Plan

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in gastrointestinal self-advocacy
Time Frame: At baseline and at 4 weeks
Will use a 4-items self-report "How confident are you in..." scale and chart-verified data to assess baseline and post-intervention self-advocacy. Questions are answered on a 5-point scale where 1=not at all confident and 5=extremely confident. Higher scores indicate greater self-advocacy confidence. Will compare mean change between arms using analysis of covariance (ANCOVA) or linear regression adjusting for baseline scores. Will estimate effect sizes (Cohen's d) and 95% confidence intervals. Sensitivity analysis will use mixed-effects models for repeated measures.
At baseline and at 4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Symptom-tracking frequency
Time Frame: Over 4 weeks
Will be defined as the number of entries logged (ALEX application or pencil-paper logs).
Over 4 weeks
Symptom-report detail and quality
Time Frame: Up to 4 weeks
Will be assessed by qualitative review of report detail (e.g., presence of descriptors, specificity, and red-flag indicators). Will be reported using descriptive summaries of coding categories.
Up to 4 weeks
Communication readiness and symptom-disclosure confidence
Time Frame: At baseline and at week 4
Will be measured by 4 self-report questions answered on a Likert-type scale where 1=not at all confident, 2=slightly confident, 3=moderately confident, 4=somewhat confident, and 5=extremely confident. Higher scores indicate greater confident in readiness to communication symptoms with confidence.
At baseline and at week 4
Intervention acceptability and usability (ALEX arm only)
Time Frame: Up to 4 weeks
Will be measured using the 2-question System Usability Scale (answered on a scale of 1-5 where 1=strongly disagree and 5=strongly agree) or other study-specific acceptability measures. Will be reported using descriptive statistics of acceptability and usability scores.
Up to 4 weeks
Engagement metrics (ALEX arm)
Time Frame: Up to 4 weeks
Will measure application analytics (days with entries, interaction with coaching modules, and notifications opened). Will be reported using descriptive summaries (median daily engagement).
Up to 4 weeks
