Breztri™ Aerosphere® now Available in Canada for Long-Term Maintenance Treatment of COPD
MISSISSAUGA, ON – Today, AstraZeneca announced the Canadian availability of Breztri™ Aerosphere® (budesonide / glycopyrronium / formoterol fumarate dihydrate), indicated for the long-term maintenance treatment to reduce exacerbations of chronic obstructive pulmonary disease (COPD) and treat airflow obstruction in patients with COPD, including chronic bronchitis and/or emphysema who are not adequately treated by a combination of an ICS/LABA or a combination of a LAMA/LABA.1
It is estimated that two million Canadians are living with COPD2, a lung condition which includes chronic bronchitis and emphysema, that causes debilitating bouts of breathlessness3,4,5 largely due to the narrowing of the airways.6 An exacerbation occurs when the symptoms of a person living with COPD intensify suddenly, requiring medical treatment.7 In Canada, COPD is the eighth leading cause of hospitalization; and in people over 65 years old, it is the fourth leading cause of hospitalization.8
“Preventing exacerbations is a key clinical priority, as even a single exacerbation can cause further deterioration of a patient’s lung function, increase the risks of hospitalization and premature death,” said Dr. Jean Bourbeau, Respirologist and Professor in the Departments of Medicine and Epidemiology & Biostatistics at McGill University. “Triple fixed-dose combination therapies, like Breztri Aerosphere, have demonstrated benefits in reducing exacerbations and mortality for eligible patients and represent an important advance in the field.”
About 70 per cent of exacerbations are not reported by patients to their physicians.9 During a severe exacerbation, symptoms like shortness of breath and increased coughing suddenly intensify, airway muscles tighten significantly and cut off air supply. This can lead to blue lips or fingers, confusion, drowsiness, extreme shortness of breath and, when not treated, death.10 One in four patients die within a year of a severe exacerbation.11
“Quality of life is everything for people living with COPD in Canada and their families,” said Peter Glazier, Executive Vice President of the Lung Health Foundation. “We’re pleased to know there is a new treatment option to help people live life to the fullest extent possible with COPD.”
“The availability of Breztri Aerosphere in Canada marks a significant advance in care for COPD patients, and reinforces our commitment to this community,” said Dr. Alex Romanovschi, Vice President, Scientific Affairs, AstraZeneca Canada. “We are proud of the potential Breztri Aerosphere has to help improve the clinical outcomes and the quality of life for people living with COPD.”
Health Canada’s approval was based on positive results from ETHOS and KRONOS Phase III trials in moderate to very severe COPD patients. In the ETHOS trial, Breztri Aerosphere showed a statistically significant reduction in the rate of moderate or severe exacerbations compared with dual-combination therapies (glycopyrronium/formoterol fumarate) and PT009 (budesonide/formoterol fumarate) over 52 weeks.12 In the KRONOS trial, which included patients with no history of exacerbations in the prior 12 months, Breztri Aerosphere demonstrated a statistically significant reduction in the rate of moderate or severe exacerbation over 24 weeks vs. a dual-combination therapy (glycopyrronium/formoterol fumarate.13
Results from the ETHOS Phase III trial were published in The New England Journal of Medicine in June 202012 and results from the KRONOS Phase III trial were published in The Lancet Respiratory Medicine in September 2018.13 In both trials, the safety profile and tolerability of Breztri Aerosphere were consistent with the profiles of the dual comparators.12,13 The most frequently reported adverse reactions were pneumonia, oral candidiasis, muscle spasms, and dysphonia.1
COPD is a progressive disease which can cause obstruction of airflow in the lungs resulting in debilitating bouts of breathlessness2,3,5 and is the third leading cause of death globally.14 Improving lung function, reducing exacerbations, managing daily symptoms, and reducing all causes of mortality are important treatment goals in the management of COPD.2 A single COPD exacerbation can have a negative impact on lung function,15,16 quality of life,17 and increase the risk of hospitalization.18 Additionally, even one COPD exacerbation that results in hospitalization is associated with an increased risk of death.19,20 The risk of a stroke increases by 40 per cent within 6 to 10 days following an exacerbation.21 In the year following an exacerbation, the risk of a cardiovascular event is four times higher within the first 30 days and increases by 90 per cent within 3 months to 12 months.22 It is also 10 times higher following a hospitalization.22
Breztri Aerosphere is a triple therapy in a single inhaler that demonstrates a statistically significant reduction in the rate of moderate or severe exacerbations. The triple therapy combines inhaled corticosteroid (ICS), long-acting muscarinic antagonist (LAMA), and a long-acting beta2-adrenergic agonist (LABA), to help reduce inflammation in the airways making it easier to breathe. Breztri Aerosphere was approved by Health Canada in July 2021.
Breztri Aerosphere is also approved for patients with COPD in Japan, China, and the US, and as Trixeo Aerosphere in Europe.
