– Results expected for Q3, 2014 –
Anergis, a company discovering and developing proprietary allergy vaccines, today announced that it has completed the enrolment of 196 subjects in the long-term efficacy trial of its birch pollen allergy vaccine AllerT, and expects to release results in the third quarter of 2014.
The long-term efficacy trial of AllerT is a double-blind, placebo-controlled, field-based clinical trial assessing the persistence of the efficacy of AllerT in post-treatment years.
All 196 patients participated in the field-based Phase IIb trial with AllerT in 2013. They all received a two-month double-blind, randomized treatment with AllerT or a placebo prior to the 2013 birch pollen season, and were then followed for efficacy during the 2013 birch pollen season, i.e. in conditions of natural pollen exposure. Last year’s Phase IIb trial had shown the efficacy of AllerT on allergy symptoms during the first post-treatment birch pollen season, based on combined symptom and medication scores, quality of life and other endpoints.
In the new long-term efficacy trial, the enrolled patients agreed to collect their daily allergy symptoms and allergy medication using electronic diaries, exactly as was done during the previous trial/season. The patients have not received any further investigational treatment since their pre-seasonal two-month treatment in early 2013.
The trial will thus provide efficacy data for AllerT during the second season post-treatment without any intervention since the initial two-month, pre-seasonal treatment. Anergis had already shown that patients from the AllerT Phase IIa trial had a persistent elevation in allergen-specific antibodies (IgG4) until at least the fourth post-treatment season.
