Anergis, a company developing breakthrough allergy vaccines for fast and safe allergen-specific immunotherapy, has been granted patent protection for its AllerT birch pollen allergy treatment in the U.S.
The patent No. 8,343,503 granted by the U.S. Patent Office broadly covers composition of matter and medical use of AllerT, the lead product of Anergis. AllerT is composed of a set of three contiguous overlapping peptides (COPs) derived from the allergen Bet v 1, which plays a key role in inducing birch pollen allergy.
AllerT is currently evaluated in a double-blind, randomized, placebo-controlled Phase IIb trial enrolling about 300 patients with moderate to severe birch pollen allergy in up to 30 trial centers throughout Europe. Results are expected in Q3, 2013. In an earlier Phase I/IIa trial, a 2-month treatment with AllerT was well tolerated by patients with moderate to severe allergy to birch pollen. In these patients, AllerT elicited long-lasting immunological responses, evidenced by significantly elevated allergen-specific IgG4 antibody levels four years after completion of the 2-month treatment with AllerT.
