Prevention of asthma symptoms
ALK is leading the industry’s research into the role respiratory allergies play in asthma. As part of this research, we conducted the world’s largest allergy immunotherapy trial ever carried out in children to investigate the effect of a new treatment on the risk of developing asthma.
The link between allergic rhinitis and allergic asthma
Respiratory allergens, such as house dust mites, can cause the airways to inflame. In time, this can lead to asthma, or the worsening of symptoms in people who are already asthmatic. A new treatment option can treat both house dust mite allergic rhinitis and allergic asthma.
