A birch allergy study is underway at Cliantha Research in Mississauga, Ontario. They are seeking healthy adults to participate in this study.

As there is cross-reactivity with birch pollen and certain fresh fruits, vegetables and tree nuts, some members in the food allergy community who may also have a birch allergy might be interested in this study or know affected individuals who could be interested.

Following is the announcement from the research team for your information and for sharing with individuals with birch allergy.

Enrolling participants for a birch allergy study

Clinical trial at Cliantha Research

Cliantha Research in Mississauga, Ontario is enrolling participants for a birch allergy study. Our experienced research team, led by Dr. Patricia Couroux, is working closely with pharmaceutical organizations to explore therapies for people with birch allergies.

What is the purpose of this study?

The study is researching study drugs called REGN5713, REGN5714, and REGN5715 in different combinations with each other to understand whether more antibodies, as compared to fewer antibodies or a single antibody, provide greater improvement in nose and eye allergy symptoms due to birch pollen allergy in adults. The aim of the study is to see how effective the study drugs are at reducing allergic nose and eye symptoms. Allergic symptoms will be observed in an Environmental Exposure Unit (EEU) (both during and not during the birch pollen season) and during the natural birch pollen season. Allergic nasal symptoms can include congestion, runny nose, and sneezing. Allergic eye symptoms can include redness, itching, and swelling.

What are REGN5713-5714-5715, REGN5713-5715, and REGN5715?

REGN5713, REGN5714, and REGN5715 are investigational monoclonal antibodies. Antibodies are proteins produced by the body to fight against different types of disease. REGN5713, REGN5714, and REGN5715 are produced in a laboratory and bind to Bet v 1. Bet v 1 is a part of birch pollen that makes most people who are allergic to birch pollen have allergy symptoms. REGN5713-5714-5715 is a mixture of all 3 antibodies and REGN5713-5715 is a mixture of just REGN5713 and REGN5715.  Please note that this clinical trial will use an investigational drug product. The safety and efficacy of which has not been fully evaluated by Regulatory Authorities, including Health Canada, and has no received marketing authorization in any country.
