It is estimated that one-quarter of the population may suffer from cat allergies. American College of Allergy, Asthma and Immunology a common and year-long condition in which exposure to cat allergens such as dander (shedding skin cells) provoke unpleasant and often disruptive symptoms. There are 77 sites across the United States and Canada participating in CATALYST, which is designed to determine whether the investigational medicine can effectively treat the symptoms of moderate to severe cat allergies with people who live with cats and have been diagnosed with the condition for at least two years.
Many people with cat allergies try managing their symptoms with prescription and over-the-counter medicines, including antihistamines, nasal corticosteroids and decongestants. Sufferers with moderate to severe cat allergies may undergo a series of allergy shots, also known as allergen immunotherapy, which works by trying to teach the immune system to tolerate cat allergens rather than fight them. Allergen immunotherapy typically begins with once- or twice-weekly injections for several months and gradually tapers in frequency to once monthly, but for as long as 3-5 years. Currently available treatment options are associated with poor patient compliance and high potential for side-effects.
