A Study to Evaluate the Efficacy and Safety of Fel d 1 Monoclonal Antibodies in Adult and Pediatric Participants With Allergic Conjunctivitis Due to Cat Allergy
A Randomized, Double-Masked, Placebo-Controlled, Phase 3 Study to Assess the Efficacy and Safety of Fel d 1 Monoclonal Antibodies in Participants With Allergic Conjunctivitis Due to Cat Allergy
This study is researching two experimental medicines, freneslerbart and mevonlerbart. Freneslerbart and mevonlerbart can be given alone or together. When given together, the medicine is called "REGN-2Cat". These medicines are also known as the "study drugs".
The aim of the study is to see what side effects freneslerbart, mevonlerbart, and REGN-2Cat may have and if they help reduce eye allergy symptoms caused by cat hair/dander compared with a placebo.
The study is looking at several other research questions, including:
- How much study drug is in the blood at different times
- Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
- How long the study drug effect lasts
