Company News: Anergis Starts Phase II Dose Ranging Trial with Birch Pollen Allergy Vaccine AllerT
– Dose assessment for upcoming Phase III trial
Anergis, a company developing proprietary ultra-fast allergy vaccines, today announced the start of a Phase II trial designed to finalize the dose selection for the Phase III study of AllerT. AllerT is Anergis´ lead vaccine against birch pollen allergy that originated from the company´s proprietary Contiguous Overlapping Peptide (COP) platform. COPs are pharmaceutical-grade, long-peptide immunotherapeutics designed for an ultra-fast, safe and long-lasting treatment of allergy patients.
The randomized, double-blind, placebo-controlled, 4-parallel-group trial will assess the dose response efficacy of AllerT across doses of 50 µg, 25 µg, 10 µg compared to a placebo in an environmental exposure chamber (EEC). Approximately 180 birch pollen allergy patients will receive 5 subcutaneous injections over 2 months. All enrolled patients will be challenged with birch pollen prior to receiving AllerT or the placebo, and 4 weeks after the last injection.
The primary endpoint is the change in Total Rhinoconjunctivitis Symptom Scores (TRSS) from the baseline EEC challenge to the post-treatment EEC challenge.
Secondary endpoints are the mean Total Nasal Symptom Scores (TNSS), Total Ocular Symptom Score (TOSS), Individual Nasal Symptom Scores (NSS) and Asthma Symptom Score (ASS), which will also be evaluated from the baseline EEC challenge to the post-treatment EEC challenge. The trial is being conducted in Canada, with results expected in the third quarter of 2015.
Company News: Anergis Obtains U.S. Patent for Lead Product AllerT
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.
