MISSISSAUGA, ON, Feb. 26, 2018 /CNW/ - AstraZeneca Canada today announced that Health Canada has approved Fasenra® (benralizumab injection) as an add-on maintenance treatment for adult patients with severe eosinophilic asthma.1
"Treatment options for patients with severe eosinophilic asthma are limited, with many relying on oral steroids to manage their symptoms, which can lead to considerable side effects," said Dr. Mark FitzGerald, Director of the Centre for Heart and Lung Health at the Vancouver Coastal Health Research Institute, University of British Columbia, and Principal Investigator of the CALIMA trial.
"Fasenra's approval means physicians have a new option for severe asthma patients with a distinct phenotype," said Dr. FitzGerald. "Its strong clinical profile offers patients the potential to experience fewer asthma attacks and thus avoid the use of oral corticosteroids, and in those patients requiring oral corticosteroids on a regular basis, the ability to reduce or even stop their use of oral corticosteroids."
Eosinophils are a type of white blood cell that are a normal part of the body's immune system.2 Elevated levels of eosinophils, seen in about half of severe asthma patients, impact airway inflammation and airway hyper-responsiveness, resulting in increased asthma severity and symptoms, decreased lung function, and increased risk of exacerbations.3,4
"Severe asthma can greatly impact patients' quality of life by limiting their capacity for physical activity, interfering with social interactions, impeding school/workplace productivity and often leads to unplanned hospital visits," said Vanessa Foran, President and CEO, Asthma Canada. "Fasenra's approval provides a much-needed option to help people with severe asthma manage this disease, so they can live active lives, symptom free."
The Health Canada approval is based on results from the WINDWARD clinical program, including the pivotal Phase III exacerbation trials.1
"We are excited to receive approval for Fasenra as this represents a significant milestone for Canadian patients with severe asthma whose disease is driven by eosinophilic inflammation," said Dr. Neil Maresky, Vice President, Scientific Affairs, AstraZeneca Canada Inc. "Fasenra is our first respiratory biologic indication in Canada, bringing us another step closer to our goal of transforming respiratory treatment for Canadian patients, particularly of severe disease."
About Severe Asthma
Asthma affects 315 million individuals worldwide5, including an estimated 3 million Canadians.6 Up to 10% of asthma patients have severe asthma3, including an estimated 250,000 Canadians6, which may be uncontrolled despite high doses of standard-of-care asthma controller medicines, and can require the use of chronic oral corticosteroids (OCS).7
Severe, uncontrolled asthma is debilitating and potentially fatal with patients experiencing frequent exacerbations and significant limitations on lung function and quality of life. 8,9,10 Severe, uncontrolled asthma has a higher risk of mortality than severe asthma.10,11
Severe, uncontrolled asthma can lead to a dependence on OCS, with systemic steroid exposure potentially leading to serious short- and long-term adverse effects, including weight gain, diabetes, osteoporosis, glaucoma, anxiety, depression,7,12 cardiovascular disease13 and immunosuppression.14 There is also a significant physical and socio-economic burden of severe, uncontrolled asthma with these patients accounting for 50% of asthma-related costs.15 A conservative estimate developed by the Conference Board of Canada suggests that without concerted action, the cost of asthma alone in Canada will rise to $4.2 billion by 2030.16
About Fasenra (benralizumab)
Fasenra is a monoclonal antibody that recruits natural killer cells to induce direct, rapid and near-complete depletion of eosinophils.17,18 Eosinophils are the biological effector cells in approximately 50% of asthma patients, leading to frequent exacerbations, impaired lung function and asthma symptoms.3,4 Fasenra is available as a subcutaneous injection via a prefilled syringe administered once every 4 weeks for the first 3 doses, and then once every 8-weeks thereafter.1
Fasenra is now approved in Canada, the US, the EU, Japan, and under regulatory review in several other countries. It represents the foundation of AstraZeneca's respiratory biologics portfolio of potential new medicines targeting underlying causes of respiratory disease. Fasenra is also being evaluated in chronic obstructive pulmonary disease (COPD).
Fasenra was developed by AstraZeneca with MedImmune, the company's global biologics research and development arm, and is in-licensed from BioWa, Inc., a wholly-owned subsidiary of Kyowa Hakko Kirin Co., Ltd., Japan.
