Study Identifies Optimal Treatment Approach for Late-Stage Development
Circassia Ltd, a specialty biopharmaceutical company focused on allergy, today announced positive results from a recently completed phase II clinical study of its ToleroMune(R) cat allergy therapy, which successfully identified the optimal dosing regimens to progress into late-stage development. The clinical trial, which was the first of its kind in the field of cat allergy immunotherapy, showed that Circassia's ToleroMune treatment was extremely well tolerated and greatly reduced sufferers' symptoms.
Circassia conducted the double-blind study in Canada, where 121 subjects with confirmed cat allergies were randomised to receive placebo or one of four different treatment regimes with standardised doses of ToleroMune. The volunteers were exposed to cat allergens (aerosolised dander) in an environmental exposure chamber for 3 hours each day on four consecutive days, both before and after treatment. At set time points the subjects scored their ocular and nasal symptoms to allow investigators to measure the effect of the ToleroMune treatment. This is the first trial of a cat allergy immunotherapy to use this validated approach.
