Dr. Rod Hafner discussed the possibilities for allergy immunotherapy at the World Vaccine Congress Lyon.
Allergies see the immune system overreact, creating a need to switch it off and bring it back to tolerance. Many patients are unsatisfied with common allergy treatments, such as antihistamines. Immunotherapy treatment options exist, where small doses of allergens are injected sub-cutaneously; however, these require a huge commitment as they can last from 3-5 years.
Circassia is working on developing a short-course allergy immunotherapy to last three months. Their lead program is focused on cat allergies. They take a different approach to common immunotherapy treatments by using T cell epitopes and administrating it intradermally.
Circassia has managed to take the program to phase III of clinical trial, and is hoping to bring the product to market.
Their product aims to be safe and well tolerated, with no side reactions; the dose should be the same for everybody. In theory, this is made possible as the therapy utilises synthetic peptides.
Clinical trials were run in chambers where individuals were exposed to cat allergen over four consecutive days, for three hours each time. The symptoms were self-reported by individuals, which differs from traditional trials. Results showed that with repeated allergen exposure treatment improved.
Overall, safety data is looking clean, according to Hafner, with treatment persisting a year, and perhaps longer…
