Anergis, a company developing breakthrough allergy vaccines for fast and safe allergen-specific immunotherapy, reported today that it has reached several preclinical development milestones with AllerR, a novel allergy vaccine candidate for the treatment of patients with allergies to ragweed pollen. In addition, the company received positive feedback from the FDA on its AllerR development program.
In the development of AllerR, its second allergy vaccine candidate, Anergis reached essential preclinical milestones and held its first meeting with the US FDA in preparation for the first clinical trial of AllerR in patients allergic to ragweed pollen.
In preclinical experiments carried out by Anergis, binding of the AllerR peptides to IgE antibodies of allergic patients remained consistently undetectable in all conditions tested. In mice pre-sensitized to ragweed pollen, AllerR, unlike natural ragweed allergens, did not elicit an anaphylaxis-like response. And, importantly, AllerR was found to elicit antibody responses in mice, in which the antibodies recognized the natural ragweed allergens. Following collection of these data, Anergis held a pre-IND meeting with the U.S. FDA during which the regulatory path was clearly established until and including the clinical Phase I trial protocol.
