BT delivered by the Alair™ System is clinically proven to be a safe and effective treatment for severe asthma, with long-lasting benefits.Asthma Intervention Research 2 (AIR2) Trial: In this trial, one of the largest sham-controlled medical device trials in pulmonary medicine, patients with severe asthma showed significant improvement compared to sham-controlled patients one year after treatment with BT.1

Clinically effective  

Proven to last at least 5 years

  • Reduction in percentage of patients experiencing exacerbations seen at 1 year maintained for at least 5 years (primary endpoint).2
  • Additionally, there was a 44% decrease (average over 5 years) in the percentage of BT-treated patients having severe exacerbations, compared with 12 months prior to BT treatment.2
  • Reduction in ER visits seen at 1 year maintained for at least 5 years.2

Proven Safety  

Asthma experts around the word say BT safe. 

  • No increase was seen in hospitalizations, asthma symptoms, or respiratory adverse events over the course of 5 years in patients treated with Bronchial Thermoplasty, delivered by the Alair System.2
  • No structural changes in the airways that were clinically significant were due to BT at 5 years.2
  • Absence of clinically significant deterioration in lung function (pre-bronchodilator FEV1 at 5 years.

Understand the risks of the Bronchial Thermoplasty procedure

As with any procedure, there are risks, and individual results may vary. The most common side effect of BT is temporary worsening of respiratory-related symptoms. This side effect typically occurs within a day of the procedure and resolves within 7 days on average with standard care. There is a small (3.4% per procedure) risk of these symptoms requiring hospitalization.1
