About Circassia’s ToleroMune® allergy treatments

Circassia is developing a range of allergy treatments based on its proprietary ToleroMune® technology. This uses small sections of allergens (epitopes) to generate regulatory T cells that suppress allergic responses and create immune tolerance in patients. The company has successfully completed a number of phase II studies with its cat, house dust mite, ragweed and grass allergy therapies. Clinical results show that short courses of Circassia’s allergy treatments can greatly reduce patients’ allergic responses, without the need for adjuvants or other immune stimulators, while proving extremely well tolerated. As a result, the treatments offer major potential clinical benefits compared with existing therapies, and have significant market opportunities. More than 150 million people suffer from allergic rhinitis in the US and Europe, and the current treatment market is valued at approximately $12 billion per year.
