MISSISSAUGA, ON, March 28, 2022 /CNW/ - Today sanofi-aventis Canada Inc. (Sanofi Canada) announced the expanded approval of Dupixent® (dupilumab injection) as an add-on maintenance treatment in patients aged six to 11 years with severe asthma with a type 2 / eosinophilic phenotype or oral corticosteroid-dependent asthma. The approval is based on the pivotal VOYAGE phase 3 trial which enrolled 408 children aged six to 11 years with uncontrolled moderate- to severe asthma. The primary endpoint of the trial was the annualized rate of severe asthma exacerbationsii.

"Dupixent is already an important treatment option for adults and adolescents disabled by severe asthma, and expanding its clinical applicability to include children aged six to 11 creates opportunities to make life better for some of the many Canadian children whose lives are restricted by their severe asthma."
Sixth indication for Dupixent, its second in asthma, and its second indication in children aged six to 11 years
Dupixent was first approved in Canada in 2017 for the treatment of adults with atopic dermatitis. Dupixent has since been approved for the treatment of adolescents and children aged six and older with atopic dermatitis; adults with chronic rhinosinusitis with nasal polyposis (CRSwNP); and adults, adolescents and now children aged six and older with severe asthma. Dupixent is the first medicine approved for the treatment of severe asthma with a type 2 inflammation phenotype. More than 8,500 Canadians have been treated with Dupixent across its various indications.

"Almost every single day, we at Sanofi hear a new story about Dupixent making a profound impact in someone's life. Now, with this pediatric indication for Dupixent, we're excited at the opportunity to potentially help Canadian children with severe asthma to have fewer attacks, and to help their parents breathe easier, too."
Asthma is a chronic inflammatory disease of the airways that causes symptoms like shortness of breath, chest tightness, coughing and wheezing. Asthma causes inflammation and narrowing of the bronchial tubes, which leads to limited airflow and difficulty breathingiii. People with severe asthma experience difficulty breathing, coughing, wheezing, and are at risk for life-threatening asthma attacks, which may require visits to the emergency room or hospitalizationiv,v. Some people with severe asthma can manage their symptoms with inhaled corticosteroids, while other people require different or additional kinds of medicine to manage their disease.
Asthma is the third-most common chronic disease among Canadiansvi,vii, and the most common chronic disease in Canadian children: 15% - 25% of Canadian children are diagnosed with asthmaviii.
Mother of a child with severe asthma
"My daughter Payton's severe asthma has definitely affected everyone in our family as we help protect her and keep her healthy, so she doesn't suffer more than she already does. From wheezing and coughing episodes to numerous trips to emergency and overnight hospital stays—we just want her to be able to run and play without constantly being wheezy and struggling to catch her breath."
President and CEO, Asthma Canada
"It's exciting to see innovation in this space and a new medication to help children living with severe asthma, where there are very few treatment options. Anything that makes life easier for a child to run around, play, and go to school—the way kids should be able to—is a tool worth having."
Dupixent is a fully human monoclonal antibody that inhibits the signaling of the interleukin-4 (IL-4) and interleukin-13 (IL-13) pathways and is not an immunosuppressant. Data from Dupixent clinical trials have shown that IL-4 and IL-13 are key and central drivers of the type 2 inflammation that plays a major role in severe asthma, atopic dermatitis, and chronic rhinosinusitis with nasal polyposis (CRSwNP).
Dupixent is being jointly developed by Sanofi and Regeneron under a global collaboration agreement. In Canada, Dupixent is jointly commercialized by Sanofi Canada and Regeneron Canada Company.
