AI-Assisted Remote Monitoring for Patients With or at Risk of Malignant Bowel Obstruction

6 novembre 2026 mis à jour par: Hospital Universitario 12 de Octubre

A Pragmatic Phase II Randomized Clinical Trial of Remote Monitoring for Patients With or at Risk of Malignant Bowel Obstruction (MBO)

The goal of this clinical trial is to learn whether artificial intelligence (AI)-assisted remote symptom monitoring can reduce hospital admissions related to malignant bowel obstruction (MBO) in patients with advanced cancer who have MBO or are at risk of developing MBO.

The main questions it aims to answer are:

  • Does AI-assisted remote symptom monitoring reduce the proportion of patients who experience at least one hospital admission due to MBO within 90 days?
  • Does AI-assisted remote symptom monitoring improve patient-reported outcomes, quality of life, healthcare resource utilization, and survival outcomes compared with standard care? Researchers will compare AI-assisted remote symptom monitoring plus standard care with standard care alone to determine whether remote monitoring can reduce MBO-related hospital admissions and improve patient outcomes.

Participants will receive study-specific assessments and follow-up for at least 90 days. Participants in the monitoring group will receive regular automated symptom-monitoring calls, and optional stool samples may be collected for microbiome research

Aperçu de l'étude

Description détaillée

This is a prospective, pragmatic, randomized phase II clinical trial evaluating AI-assisted remote symptom monitoring in patients with advanced cancer who have MBO managed in the outpatient setting or are at risk of developing MBO. All participants will receive standard clinical management according to local standard of care, as well as educational materials regarding MBO, symptoms requiring medical attention, symptom management recommendations, and dietary advice.

Eligible participants will be identified using the Princess Margaret Malignant Bowel Obstruction (PMMBO) risk stratification system. Patients classified as yellow (at risk of MBO) or orange (outpatient MBO) will be eligible for the study. Participants who meet the eligibility criteria will be randomized in a 1:1 ratio to either the AI-assisted remote monitoring arm or the standard-of-care arm. Randomization will be stratified by previous MBO-related hospital admission (yes/no), baseline PMMBO risk category (yellow/orange), and study site.

This study consists of two study arms:

  • Standard-of-Care Arm: Participants randomized to this arm will receive routine clinical follow-up and management according to local institutional practice.
  • AI-Assisted Remote Monitoring Arm: Participants randomized to this arm will receive standard care plus remote symptom monitoring through an AI-based conversational platform. The platform will perform structured symptom assessments through automated telephone calls using a predefined questionnaire focused on MBO-related symptoms. Monitoring will be performed at least once per week and may be increased according to patient symptoms and clinical needs. Participant responses will be assessed in real time and predefined alerts will be displayed through a nursing dashboard, allowing healthcare professionals to review symptoms and initiate clinical interventions when considered necessary.

A total of 140 participants will be enrolled and randomized, with 70 participants assigned to each study arm. Participants will undergo baseline and follow-up assessments according to the study schedule and will be followed for at least 90 days after randomization. Monitoring in the intervention arm may continue beyond Day 90, if clinically indicated, for a maximum duration of 12 months.

The estimated recruitment period is 24 months

Change in quality of life
Délai: Baseline and Day 90 (±14 days)

Change from baseline in quality of life assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) questionnaire and gastrointestinal symptom subscale. The EORTC QLQ-C30 is a validated questionnaire used to assess health-related quality of life in patients with cancer. Scores range from 0 to 100. Higher scores on functional and global health status scales indicate better functioning and quality of life, whereas higher scores on symptom scales indicate greater symptom burden.

The gastrointestinal symptom subscale evaluates the severity and frequency of gastrointestinal symptoms associated with malignant bowel obstruction. Higher scores indicate greater symptom burden and worsening gastrointestinal symptoms.
