• Contiguous Overlapping Peptide allergy immunotherapeutic AllerT confirms sustained efficacy in the second year following treatment
EPALINGES, Switzerland, February 23, 2015 – Anergis, a company developing novel and proprietary ultra-fast allergy immunotherapeutics, presented detailed data from the Phase IIb trial of its birch pollen allergy immunotherapeutic AllerT in two separate scientific posters at the AAAAI (American Academy of Allergy, Asthma and Immunology) Annual Meeting in Houston, Texas. The findings were presented on February 22, 2015. Abstracts can be found at www.anergis.ch. AllerT is Anergis´ most advanced long-peptide immunotherapeutic and based on the company´s proprietary Contiguous Overlapping Peptide (COP) platform.
In 2013, the clinical efficacy of AllerT was demonstrated in a field-based, randomized, placebo-controlled, double-blind trial in 239 patients with birch pollen allergy, who received either AllerT (at 50µg or 100µg doses) or a placebo during a 2-month immunotherapy regimen. All main efficacy and safety endpoints were met in this study.
In 2014, the sustained efficacy of AllerT was assessed in the same group of patients during a second follow-up season without additional treatment. In both years, efficacy was evaluated using combined Rhinoconjunctivitis Symptom and Medication Scores (RSMS) as the primary endpoint as well as quality of life (Mini RQLQ) and Night-time Nasal Symptom Score (NNSS) as the main secondary endpoints. The study also measured the levels of allergen-specific immunoglobulins (Bet v 1 specific IgG4) in patients.
The data collected during the second post-treatment season (N=196 patients) proved the sustained efficacy of AllerT, as demonstrated by improvements in the primary endpoint, RSMS, and in the main secondary endpoints, Mini RQLQ and NNSS. The trial also confirmed that AllerT had induced a persistent elevation of anti-Bet v 1 IgG4 antibodies, i.e. measured after one year without treatment.
“The clinical and immunological data presented at the AAAAI clearly demonstrate that AllerT can induce long-lasting clinical efficacy and immune responses in birch pollen allergy sufferers under real life conditions,” said Christophe Reymond, Chief Scientific Officer of Anergis. “These findings confirm previous immunological results that were obtained four years after a single 2-month treatment with AllerT in our phase I/IIa study. We are therefore very confident that our COP allergy immunotherapeutics provide long-term allergy relief.”
