Teva Asthma Predictive Analytics Study

June 19, 2025 updated by: Njira Lugogo, University of Michigan

Utilizing Advances in Digital Inhaler Technology to Understand Heterogeneous Treatment Responses to Biologics in Severe Asthma

This trial is being completed to determine baseline inhalation parameters and patterns of use in patients receiving treatment with TEVA digital inhalers, to develop predictive models for asthma exacerbations and response to biologics using data collected from these devices.

Enrolled participants will complete questionnaires along with other study specific procedures. Additionally, in-person and phone visits will be performed.

Study Overview

Detailed Description

All participants were provided an AirDuo® Digihaler™ and ProAirDuo® Digihaler™, which the participants could choose to use or not. This trial did not restrict participants from using other asthma treatments in addition to or in lieu of the Digihalers.

Description

Inclusion Criteria:

  • A history of severe persistent asthma as defined by European Respiratory Society (ERS) and American Thoracic Society (ERS/ATS) criteria which includes the presence of poor asthma control on high dose inhaled corticosteroid (ICS) and a long-acting beta-agonist (CS/LABA) or the need for high dose ICS/LABA to maintain asthma control or oral steroids for maintenance therapy for more than 50% of the prior year.
  • Presence of current biologic use or planned initiation of biologics following study enrollment
  • Patients will be categorized on the basis of asthma control (Asthma Control Test (ACT)< 19 will be considered poor asthma control). The study will cap the patients with good asthma control at 30% and will no longer enroll those patients once the strata have been fully enrolled.
  • Willingness to switch maintenance inhalers to AirDuo® Digihaler™ and to use ProAir® Digihaler™ for rescue therapy. Use of nebulized albuterol will be discouraged but not prohibited.
  • Can read and communicate in English and is familiar with and is willing to use his/her own smart device and download and use the study application
  • Ability to provide informed consent.
  • The patient must be willing and able to comply with study requirements and restrictions

Exclusion Criteria:

  • Clinically important pulmonary disease other than asthma including Chronic obstructive pulmonary disease (COPD), bronchiectasis, pulmonary fibrosis, cystic fibrosis, or other lung disease
  • Any disorder that is either not stable or could in the opinion of the investigator affect the ability of the subject to safely participate in the study or could adversely affect study results.
  • History of human immunodeficiency virus or other immunodeficiency syndrome
  • Malignancy other than skin cancer that has occurred within the past year and that will impact survival thus limit participation in the clinical trial
  • History of chronic alcohol abuse or drug use
  • Any life-threatening diseases that will impact the patient's ability to complete the 12-month study period

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: AirDuo and ProAir
This trial includes using the inhaler (AirDuo®) Digihaler™ and rescue inhalers (ProAir®) Digihaler™.

Participants will receive the AirDuo® Digihaler™ at a dose that is equivalent to the participants' current inhaled therapy dose. Most participants will likely require the high dose inhaler: 232/14 device. This medication will be administered twice daily. The study and treatment will last 1 year.

Participants will also use a home spirometry device and smart device application (app) will be used to track medication usage and allow users to self-assess their respiratory symptoms on a daily basis.

Participants will receive the ProAir® Digihaler™ 90mcg at a dose that is equivalent to the participants' current inhaled therapy dose. Most participants will likely require the high dose inhaler: 232/14 device. The ProAir® Digihaler™ will be utilized up to six times per day as needed for acute asthma symptoms. The study and treatment will last 1 year.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Mean Number of Daily Doses of ProAir® Digihaler™
Time Frame: up to 1 year
This outcome measured participant adherence to using the ProAir® Digihaler™. All participants were provided the Digihaler device, which they could choose to use or not. Subject-specific result was calculated as the sum total of doses taken by participant divided by their number of days of follow-up.
up to 1 year
Mean Number of Daily Doses AirDuo® Digihaler™.
Time Frame: up to 1 year
This outcome measured participant adherence to using the AirDuo® Digihaler™. All participants were provided the Digihaler, which they could choose to use or not. Subject-specific result was calculated as the sum total of doses for a given participant divided by their number of days of follow-up.
up to 1 year
Median Number of Daily Doses of ProAir® Digihaler™
Time Frame: up to 1 year
This outcome measured participant adherence to using the ProAir® Digihaler™. All participants were provided the Digihaler, which they could choose to use or not. Subject-specific result was calculated as the 50th percentile value of all daily dose totals (or the average of two 50th percentile values if there was a tie) calculated over the number of days of follow-up.
up to 1 year
Median Number of Daily Doses of AirDuo® Digihaler™
Time Frame: up to 1 year
This outcome measured participant adherence to using the AirDuo® Digihaler™. All participants were provided the Digihaler, which they could choose to use or not. Subject-specific result was calculated as the 50th percentile value of all daily dose totals (or the average of two 50th percentile values if there was a tie) calculated over the number of days of follow-up.
up to 1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maintenace Inhaler Adherence Rates
Time Frame: up to 1 year
This outcome measured participant adherence to using the AirDuo® Digihaler™. All participants were provided the Digihaler, which they could choose to use or not. Adherence rates were measured by the following: High (>80% of puffs), moderate (50-80% of puffs), and low levels (<50% of puffs) of adherence to maintenance inhalers over the course of the trial.
up to 1 year
Participants Who Achieved Non-response, Partial Response, and Complete Response to Biologics
Time Frame: up to 1 year
All participants were provided the AirDuo® and ProAir® Digihalers, which they could choose to use or not. Responses were categorized as non-response, partial response, and complete response on the basis of five factors: a 50% reduction in exacerbations, any reduction in maintenance oral corticosteroids (OCS) dose, change of at least 10% in forced expiratory volume in one second (FEV1), improvement of 3 points in asthma control test (ACT) score, and patient perception of global improvement in asthma. Non-response indicated that a participant had no response to any of the 5 factors. Partial response indicated that a participant responded to at least 1 factor. Complete response indicated that a participant responded to all 5 factors.
up to 1 year
Change in Mean Peak Inhalation Volume
Time Frame: baseline to 1 year
Peak inhalation volume is the maximum air volume a person can breathe in during a deep inhalation, serving as an indicator of lung capacity and respiratory function. Peak inhalation volume was measured by the digital inhaler at the end of inhalation. This measures the maximum volume that the participant was able to draw into their lungs. Larger numbers indicated healthier lungs.
baseline to 1 year
Change in Mean Inspiratory Time
Time Frame: baseline to 1 year
Inspiratory time was the total time taken to complete an inspiration (i.e., breathing in). Results were differences between the baseline and exacerbation measurements.
baseline to 1 year
Change in Mean Peak Inspiratory Flow (PIF)
Time Frame: baseline up to 1 year
PIF is the maximum rate of airflow a person can inhale using an inhaler after a full breath. PIF was measured by the ProAir® Digihaler™ and AirDuo® Digihaler™. Results indicate the changes between the baseline and exacerbation measurements.
baseline up to 1 year
Change in Mean Forced Expiratory Volume in One Second (FEV1)
Time Frame: baseline up to 1 year
FEV1 was measured using the Go Spiro Spirometer. Results indicate the difference between the baseline and exacerbation measurements.
baseline up to 1 year
