A Study to Examine the Efficacy and Safety of Anti-Fel d 1 Antibodies Injections in Cat-allergic Adolescent and Adult Patients With Allergic Rhinitis Who Live With a Cat
- Conditions
- Allergic Rhinitis Due to Cat Allergy
- Interventions
- Drug: Matching Placebo
- Registration Number
- NCT04981717
- Lead Sponsor
- Regeneron Pharmaceuticals
- Brief Summary
The primary objective of the study is to determine the efficacy of REGN1908-1909, as compared to placebo, to reduce allergic rhinitis/conjunctivitis symptoms and allergy rescue medication use during natural cat exposure.
The Secondary Objectives are:
* To assess the reduction of allergic symptoms and use of allergy rescue medications after treatment with REGN1908-1909 versus placebo, as measured by the individual components of the CSMS
* To assess health-related quality of life (HRQoL) as measured by the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ\[S\])
* To determine the efficacy of REGN1908-1909, as compared to placebo, to inhibit a wheal-and-flare response to a skin prick test with cat allergen
* To assess the durability of effect in allergic rhinitis and conjunctivitis symptom and medication scores after multiple doses of REGN1908-1909 compared to placebo given every 12 weeks (Q12W)
* To determine the efficacy following multiple doses of REGN1908-1909 compared to placebo at inhibiting a wheal-and-flare response to a skin prick test with cat allergen
* To estimate the effect of REGN1908-1909 on lung function, as compared to placebo, in patients with asthma
* To determine the efficacy of REGN1908-1909 as compared to placebo to reduce asthma symptoms in patients with asthma
* To assess whether there is a difference in asthma rescue medication use in patients with asthma who are treated with REGN1908-1909 compared to placebo
* To assess whether there is a difference in nighttime awakenings in patients with asthma treated with REGN1908-1909 compared to placebo
* To evaluate the short-term and long-term safety and tolerability of REGN1908-1909, including the incidence of hypersensitivity reactions, local injection site reactions, and asthma exacerbations
* To determine systemic exposure of total (free and antigen-bound) antibodies as measured by concentration of REGN1908 and REGN1909
* To assess the immunogenicity of REGN1908 and REGN1909

Asthma Daily Symptom (ADS) Score, Averaged Over the Initial 12 Weeks of the Treatment Period Using Asthma Daytime Symptom Diary (ADSD) and the Asthma Nighttime Symptom Diary (ANSD) in Participants With Asthma Who Receive REGN1908-1909 Versus Placebo Weeks 0 to 12 The total daily asthma symptom score is a participant-reported outcome concerning the occurrence of asthma symptoms and their effect on a patient's daily activities and sleep. It is composed of two parts: daytime (five items) and nighttime (four items), both scored ordinally. Higher scores indicate more severe symptoms. The ADSD score will be based on 6 patient-reported symptoms (difficulty breathing, wheezing, shortness of breath, chest tightness, chest pain, and cough at their worst using an 11-point numeric rating scale (NRS) ranging from 0 ('None') to 10 ('As bad as you can imagine').

Each of the 2 symptoms is graded on a Likert scale ranging from 0 (none) to 3 (severe).
Change From Baseline to Week 60 in Asthma Control Questionnaire 5 Question Version (ACQ-5) in Participant With Asthma Who Receive REGN1908-1909 Versus Placebo Baseline to week 60 The ACQ-5 had 5 questions, reflecting the top-scoring five asthma symptoms: woken at night by symptoms, wake in the mornings with symptoms, limitation of daily activities, shortness of breath and wheeze. Participants were asked to recall how their asthma had been during the previous week and to respond to each of the five symptom questions on a 7-point scale ranged from 0 (no impairment) to 6 (maximum impairment). ACQ-5 total mean score was mean of the scores of all 5 questions and, therefore, ranged from 0 (totally controlled) to 6 (severely uncontrolled), higher scores indicated lower asthma control.
