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
