Cat allergy is the most common animal allergy, affecting approximately 1 in 5 adults worldwide. The prevalence of allergy to furry animals is increasing, and cat allergy is a major risk factor for the development of asthma and rhinitis.
Fel-d1 is the major feline allergen, to which 95% of cat allergic people react. All cats produce Fel-d1 regardless of breed, age, coat type, sex or weight. Fel-d1 is contained primarily in the saliva and sebum of cats.
This allergy manifests itself as allergic rhinitis (AR) (sneezing, cold, coughing, conjunctivitis with watering and itching), severe asthma, and irritation and swelling of the skin when scratched.
A new approach to managing cat allergies is to neutralize the allergens at the source by feeding domestic cats a diet containing anti-Fel-d1 IgY antibodies. The purpose of this pilot study is to determine whether feeding domestic cats a food containing an egg product with anti-Fel d1 IgY (PRO PLAN® LIVECLEAT®) induces a reduction of allergic symptoms in their owners.
|Condition or disease||Intervention/treatment|
|Rhinitis, Allergic||Other: Cats fed with PRO PLAN® LIVECLEAT®|
|Study Type :||Observational|
|Estimated Enrollment :||50 participants|
|Official Title:||Evaluation of the Ability of a Cat Food to Reduce Respiratory Symptoms in Cat Allergic Patients: Pilot Study|
|Actual Study Start Date :||May 6, 2022|
|Estimated Primary Completion Date :||April 5, 2023|
|Estimated Study Completion Date :||April 15, 2023|
- Other: Cats fed with PRO PLAN® LIVECLEAT®
Patient with domestic cats fed with an egg product containing anti-Fel d1 IgY (PRO PLAN® LIVECLEAT®)
- Change of the global Visual Analogic Scale (VAS) mean from Baseline period (Day 0- Day 15) at end period (Day 98-Day112) [ Time Frame: Baseline (Day 0- Day 15) and observation period (Day 98-Day112) ]The approach will be considered beneficial if there is a statistically significant decrease in this criterion on the D98-J112 period compared to the baseline.
