ASIT Biotech Reviews the Efficacy Results of gp-ASIT+

ASIT biotech reviews the efficacy results of gp-ASIT+™ observed during the phase III trial completed in 2016

Brussels, Belgium 14 December 2017, 6.00 pm (CET) – ASIT Biotech (ASIT - BE0974289218), a Belgian biopharmaceutical company specialising in allergen immunotherapy, reviews and details the results of the first Phase III trial with gp-ASIT+™ presented by Professor R. Mösges (University of Cologne) and Professor M. Shamji (Imperial College London) at the 2017 Annual EAACI Congress (European Academy of Allergy and Clinical Immunology).

The efficacy of gp-ASIT+™ is measured by the reduction in symptoms and the intake of common rescue medications like antihistamines or intranasal corticosteroids during the pollen season. This is referred to as a reduction in the Combined Symptom and Medication Score (CSMS). This score is calculated on the basis of data on symptoms and medication use recorded every day in a diary by each patient.

The results presented to the EAACI show that over the course of the whole pollen season, gp-ASIT+™ resulted in an average reduction in the combined score of 17.9% for the entire study population, close to the threshold of 20% required by the registration authorities. The effects of gp-ASIT+™ were greater and exceeded this threshold of 20% (24.4%) for the most allergic group of patients (representing 50% of the total population). These effects were even more marked (53.7%) for patients recruited in Belgium

The differences in efficacy between these groups of patients are linked to variability in the severity of their allergy as well as differences in pollen levels between the regions of Europe in which the study was conducted. The exceptional results achieved in Belgium can be explained by the optimum combination of patients who were severely allergic and a normal season in terms of grass pollen exposure.

This optimum combination in Belgium created the best possible conditions for conducting the study into the immunological mechanism of gp-ASIT+™ as initially planned. This study showed that gp-ASIT+™ was capable of achieving development of an optimal immune tolerance in only 3 weeks, whereas competing products take months, or even years, of treatment to achieve comparable results.

The results of this first study in Phase III confirm that gp-ASIT+™ is capable of achieving a reduction in the combined score above the threshold of 20% demanded by the registration authorities. In view of this, for its next clinical trials with gp-ASIT+™, ASIT biotech has decided to maximize chances of success, in particular by using electronic diaries to significantly improve patient monitoring and by recruiting more patients with a severe allergy.

Within this context, the latest response from the FDA, which focuses on a limited number of clarifications on the gp-ASIT+™ master file, can be seen as a positive, significant advance in the definition of the clinical development plan in the United States. This development plan will be discussed at a meeting with the FDA.
