Automated Inhaler Monitoring for Asthma Medication Usage (AIM)

April 7, 2026 updated by: Wanda Phipatanakul, Boston Children's Hospital

The goal of this clinical trial is to evaluate the aflo™ digital platform's ability to improve inhaler use technique and asthma control for children, adolescents, and adults with uncontrolled asthma. The main questions the trial aims to answer are:

  1. Does the platform improve medication adherence and inhaler technique, as measured by the Inhaler Proficiency Score (IPS)?
  2. Does the aflo™ platform improve asthma control, as measured by changes in the Asthma Control Test (ACT) and lung function tests (FEV1, PEF)?

Participants will:

  • Use the aflo™ sensor with their asthma inhaler to receive real-time feedback on technique and medication adherence reminders.
  • Track asthma symptoms and quality of life through a mobile app.
  • Complete assessment visits and surveys at the start and end of the 3-month study and 2 interim asthma assessment phone calls.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  3. Females or males between the ages of 10 years and older
  4. Participant or caregiver must have an Apple and/or Android smart phone with operating system 4.3 or above and data plan for the duration of the study period

Exclusion Criteria:

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention group

Participants will use the aflo™ digital platform, which includes an electronic inhaler sensor, a mobile application, and a clinician portal. The platform provides real-time feedback on inhaler technique and sends medication reminders to improve adherence. Participants will also receive daily symptom tracking prompts and monthly Asthma Control Test (ACT) assessments.

During the study, participants will:

  • Attach the aflo™ sensor to their metered-dose inhaler (MDI) and use it with or without a spacer, based on their prescribed regimen.
  • Complete at least one supervised inhalation session during the baseline visit to ensure proper use of the sensor.
  • Use the aflo™ mobile app to log asthma symptoms, medication usage, and track reminders.
  • Participate in two clinic visits (at baseline and study completion) and two follow-up phone calls (at weeks 4 and 8) to monitor progress.
Device: Smart Inhaler Monitoring Platform for Asthma Management

The intervention utilizes the aflo™ digital platform, a comprehensive system designed to improve asthma management through advanced technology. It integrates the following components:

  1. Electronic Inhaler Sensor: The sensor attaches to a metered-dose inhaler (MDI) and a spacer (if applicable) to automate and provide feedback on the six critical steps of proper inhaler technique, such as shaking the inhaler, breathing out, inhaling slowly, and holding the breath. The sensor also records and stores medication usage data securely.
  2. Mobile Application: The app delivers real-time notifications and feedback on inhaler technique, sends reminders for daily controller medication, tracks asthma symptoms, and provides monthly Asthma Control Test (ACT) assessments. It also offers reminders for spacer cleaning and customizable alerts for caregivers.
  3. Clinician Portal: Data collected from the sensor and app is accessible via a secure clinician portal, enabling healthcare providers to monitor pa

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 from Baseline in the participants' Inhaler Proficiency Score (IPS) Following Aflo™ Platform Usage at 3 Month
Time Frame: From enrollment to the end of intervention period at 12 weeks
Inhaler Proficiency Score (IPS) is a validated, composite score that assesses the accuracy and consistency of inhaler technique, including steps such as inhaler preparation, actuation timing, inhalation depth, and breath hold. Scores range from 0 to 10, with higher scores indicating greater inhaler technique proficiency. Scores will be recorded at baseline and again after 3 months of using the Aflo™ digital platform, which provides step-by-step guidance and real-time feedback on inhaler technique. The outcome measure reflects the mean change in IPS from baseline to the 3-month follow-up to evaluate the effectiveness of the intervention.
From enrollment to the end of intervention period at 12 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
Evaluation of the aflo™ Platform for Improving Asthma Control Using ACT Scores
Time Frame: From enrollment to the end of intervention period at 12 weeks
This study assesses the impact of the aflo™ platform on asthma control, measured by changes in Asthma Control Test (ACT) scores. The ACT is a validated questionnaire used to evaluate asthma management, with scores ranging from 5 (poor control) to 25 (complete control). Participants will use the aflo™ platform, which provides real-time inhaler usage feedback via a connected device and mobile app. ACT scores will be collected at baseline and after the intervention to determine the platform's effectiveness in improving asthma outcomes.
From enrollment to the end of intervention period at 12 weeks
Impact of the aflo™ Platform on Health-Related Quality of Life and Clinical Outcomes in Asthma
Time Frame: From enrollment to the end of intervention period at 12 weeks
This study evaluates secondary outcomes of the aflo™ platform, including maximal percent changes in self- and parent-reported health-related quality of life using the St. George's Respiratory Questionnaire (SGRQ). Additional clinical outcome measures, such as lung function and symptom changes, will also be assessed. These measures aim to further understand the platform's effect on asthma management beyond asthma control.
From enrollment to the end of intervention period at 12 weeks
