AB Science to present results from its Phase 3 AB07015 study in severe asthma at the 2020 American Thoracic Society International Conference
Platform presentation will be included in a mini-symposium on
Late Breaking Clinical Trials in Airway Diseases being held on Monday, May 18, 2020
AB Science SA (Euronext - FR0010557264 - AB) today announced that an abstract reporting results from its Phase 3 AB07015 study on severe asthma uncontrolled by oral corticosteroids (OCS), has been selected for oral platform presentation at the upcoming American Thoracic Society (ATS) 2020 International Conference in Philadelphia, USA (May 15-20, 2020).
Pascal Chanez, Professor of Respiratory Diseases at Aix-Marseille University, France, will present key data from the positive Phase 3 study, AB07015, as part of a mini symposium session entitled ‘Late Breaking Clinical Trials in Airway Diseases’.
ATS is one of the world’s largest meetings for pulmonary medicine professionals and has been historically well-attended by key opinion leaders and decision-makers in asthma research and healthcare policy.
Pascal Chanez said: “Selection of this abstract for a platform presentation on late-breaking clinical trials at the upcoming annual ATS Conference in Philadelphia is an indication of the clinical relevance of study AB07015 and masitinib potential impact on the treatment landscape for severe asthma”.
Olivier Hermine (President of the Scientific Committee of AB Science and member of the Académie des Sciences in France) said: “Unlike the biologic that are suited for patients with severe asthma associated with high eosinophils only, masitinib is effective regardless of the eosinophil level. This is due to its mechanism of action which is more global. Biologics targets eosinophils to reduce their quantity, whereas masitinib target mast cells which play a central role in asthma. In addition masitinib target PDGF receptor that seems to play a role in airway remodeling”.
Details for the presentation are as follows:
Presentation Title: Masitinib Significantly Decreases the Rate of Asthma Exacerbations in Patients with Severe Asthma Uncontrolled by Oral Corticosteroids: A Phase 3 Multicenter Study
Session Title: Mini Symposium on Late Breaking Clinical Trials in Airway Diseases (B93)
Date/Time: Monday May 18, 2020 2:15 PM - 4:15 PM
Phase 3 study (AB07105) evaluating oral masitinib in severe asthma uncontrolled by oral corticosteroids met its primary endpoint. The pre-specified primary analysis was conducted in the severe asthma population with daily OCS ≥ 7.5 mg and masitinib treatment was associated with a significant reduction in severe asthma exacerbations (p=0.0103).
Detailed results will be presented during the conference. It is the policy of the ATS that all scientific research-related content included in an abstract to be presented at the ATS International Conference be withheld until after the abstract has been presented at the conference.
Masitinib has a unique positioning in severe asthma, in terms of administration (oral administration), mechanism of action, targeted population, and broad eosinophil level.
Masitinib is a first in class oral drug in severe asthma, selectively targeting mast cells through inhibition of tyrosine kinases c-Kit, LYN and FYN. There is a strong scientific rationale to target mast cells in asthma and study AB07015 was the first positive large-scale study in severe asthma utilizing a drug targeting mast cells [1]. Additionally, masitinib is a potent inhibitor of Platelet-Derived Growth Factor Receptor (PDGFR), which is associated with airway remodeling in asthma [2]. Masitinib is therefore capable of simultaneously modulating independent mechanisms of asthma pathophysiology, which is an attractive therapeutic strategy for severe asthma.

About masitinib
Masitinib is a new orally administered tyrosine kinase inhibitor that targets mast cells and macrophages, important cells for immunity, through inhibiting a limited number of kinases. Based on its unique mechanism of action, masitinib can be developed in a large number of conditions in oncology, in inflammatory diseases, and in certain diseases of the central nervous system. In oncology due to its immunotherapy effect, masitinib can have an effect on survival, alone or in combination with chemotherapy. Through its activity on mast cells and microglia and consequently the inhibition of the activation of the inflammatory process, masitinib can have an effect on the symptoms associated with some inflammatory and central nervous system diseases and the degeneration of these diseases.
