Study Details

Study Description

Brief Summary

The purpose of this study is to evaluate the safety and efficacy of the Alair System for the treatment of severe refractory asthma.

This will be a multicenter, randomized controlled study comparing the effects of treatment with the Alair System to standard drug therapy in patients with severe asthma refractory to standard medication therapy. A total of 30 subjects will be randomized 1:1 to the Alair Group (Medical management + Alair Treatment) OR the Control Group (Medical management only).

Condition or Disease Intervention/Treatment Phase
  • Procedure: Bronchial Thermoplasty with the Alair System
  • Drug: Control
N/A

Detailed Description

Multicenter, randomized, clinical trial conducted at 8 Investigational Sites in 3 countries.

Subjects in the Alair group to be administered the Alair treatment in 3 separate bronchoscopy sessions, while subjects in the Control group will complete 3 "Control Visits" to the Physicians office, timed to coincide with the 3 treatment bronchoscopy sessions. Following completion of all three procedures or Control Visits subjects will be evaluated at 6 weeks and 12 weeks. All subjects to remain on their maintenance asthma medications until they are evaluated again at 22 weeks after the last procedure or Control Visit. This phase from the last procedure or Control Visit out to 22 Weeks after the last procedure or Control Visit is termed the Steroid Stable Phase.

Subjects will undergo a 14 week period from 22 Weeks to 36 Weeks (termed the Steroid Wean Phase) during which an attempt will be made to wean them off either their maintenance inhaled corticosteroids (ICS) or, if taking maintenance oral corticosteroids (OCS), their oral steroids. If a subject cannot tolerate the steroid reduction at a particular level (as evidenced by loss of asthma control), they will be stabilized on their last tolerable dose of steroid.

All subjects will maintain their reduced steroid dosage from the end of the Steroid Wean Phase at 36 weeks to their final evaluations at the end of the Study at 52 weeks (termed the Reduced Steroid Phase). All subjects will be exited from the study following completion of the 52 week evaluations.

    Outcome Measures

    Primary Outcome Measures

    1. Respiratory Adverse Events Per Subject [Baseline, 12 Months]

      Respiratory adverse events (AEs) per subject reported during the Treatment Period, and Post-Treatment Period (Steroid Stable Phase, and Steroid Wean and Reduced Steroid Phase). Results were calculated by dividing the number of respiratory adverse events during each time period by the number of subjects in each group. Statistics were not calculated.

    Secondary Outcome Measures

    1. Use of Maintenance Medications (Change From Baseline) [Baseline, 12 Months]

      Percent Change from Baseline at 12 Months (Steroid Wean and Reduced Steroid Phase) Follow-up Visit in dose of inhaled and/or oral corticosteroids.

    2. Use of Rescue Medications (Change From Baseline) [Baseline, 12 Months]

      Change from Baseline at 22-Weeks (Steroid Stable Phase) and 12 Months (Steroid Wean and Reduced Steroid Phase) Follow-up Visits in use of rescue medications. Rescue medications for asthma are short-acting beta-agonists that bring quick relief of asthma symptoms.

    3. Total Symptom Score (Change From Baseline) [Baseline, 12 Months]

      Change from Baseline at 22-Weeks (Steroid Stable Phase) and 12 Months (Steroid Wean and Reduced Steroid Phase) Follow-up Visits in Total Symptom Score. The Total Symptom Score comprises the sum of six asthma symptom measurements recorded in a Daily Diary. Each of these symptoms is scored on a scale of 0 to 3 each day by the subject. The sum of the scores for these 6 symptoms comprises the Total Symptom Score, which measures overall asthma symptoms. The maximum score possible is 18. A lower Total Symptom Score represents better asthma control.

    4. Pre-Bronchodilator FEV1 (Percent Predicted) (Change From Baseline) [Baseline, 12 Months]

      Change from Baseline at 22-Weeks (Steroid Stable Phase) and 12 Months (Steroid Wean and Reduced Steroid Phase) Follow-up Visits in forced expiratory volume in one second (FEV1). FEV1 is the volume of air expired during the first second of a maximal effort expiration started at total lung capacity.

    5. Post-Bronchodilator FEV1 (Percent Predicted) (Change From Baseline) [Baseline, 12 Months]

      Change from Baseline at 22-Weeks (Steroid Stable Phase) and 12 Months(Steroid Wean and Reduced Steroid Phase) Follow-up Visits in forced expiratory volume in one second (FEV1). FEV1 is the volume of air expired during the first second of a maximal effort expiration started at total lung capacity.

    6. Asthma Control Questionnaire (ACQ) Score (Change From Baseline) [Baseline, 12 Months]

      Change from Baseline at 22-Weeks (Steroid Stable Phase) and 12 Months (Steroid Wean and Reduced Steroid Phase) Follow-up Visits in Asthma Control Questionnaire (ACQ) score. The ACQ is a self-administered patient questionnaire that assesses individual subject asthma control. The ACQ comprises 6 questions that relate to the patient's asthma symptoms, activity limitations, and daily rescue bronchodilator use, and FEV1. Each question is scored from 0 (Better) to 6 (Worse). The ACQ is based on a one-week recall period. A decrease in the ACQ score indicates better asthma control.

    7. Asthma Quality of Life Questionnaire (AQLQ) Score (Change From Baseline) [Baseline, 12 Months]

      Change from Baseline at 22-Weeks (Steroid Stable Phase) and 12 Months(Steroid Wean and Reduced Steroid Phase) Follow-up Visits in Asthma Quality of Life Questionnaire (AQLQ) score. The AQLQ is a self-administered patient questionnaire that assesses four aspects or domains of daily life for patients with asthma: symptoms, emotional function, activity limitations, and environmental stimuli. The AQLQ is based on a 2-week recall period and consists of 32 questions, each scored from 1 (Worse) to 7 (Better). An increase in the AQLQ score indicates a better quality of life.
