ASTHMAXcel Voice: a smartphone voice tool to help manage asthma

Conducting a Randomized Controlled Trial for A Novel Patient-Facing Mobile Platform to Collect and Implement Patient-Reported Outcomes and Voice Biomarkers in Underserved Adult Patients With Asthma

Not applicable Interventional Montefiore Medical Center · NCT06935084

This project will test if the ASTHMAXcel Voice smartphone app, which uses a 6-second voice sample to detect worsening symptoms, helps people with persistent asthma improve control and self-management compared with usual care.

What this trial studies

Researchers will run a randomized controlled trial comparing the adapted ASTHMAXcel Voice platform to usual care among English-speaking patients with persistent asthma on daily controller medication. The app combines patient-reported outcomes, educational videos, goal setting, personalized algorithms, push notifications, and a 6-second voice sample analyzed by machine learning to produce a Respiratory Symptoms Risk Score (RSRS). The platform also supports shared decision-making, screens for social determinants of health, enables referrals, and allows remote care coordination to promote medication adherence and self-management. Primary outcomes include clinical and process measures, asthma quality of life, medication adherence, and self-efficacy.

Who should consider this trial

Good fit: Ideal candidates are English-speaking patients with provider-diagnosed persistent asthma who take a daily controller medication, can provide informed consent, and own an iOS or Android smartphone with a data plan.

Not a fit: People who are pregnant, have severe psychiatric or cognitive impairments, do not speak English, or lack smartphone/data access are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the app could reduce asthma exacerbations, emergency visits, and hospitalizations while improving quality of life and self-management, particularly for underserved patients.

How similar studies have performed: A prior AHRQ-funded pilot of ASTHMAXcel PRO showed significant reductions in steroid use, ED visits, and hospitalizations, but the voice-biomarker approach in ASTHMAXcel Voice is newer and less tested.
