Positive new clinical data with house-dust mite immunotherapy
~ House-dust mite immunotherapy shown to be well-tolerated and demonstrates highly significant symptom improvement ~
~ Allergy experts present an overview of adjuvants at satellite symposium during EAACI 2018 ~
29 May 2018 Allergy Therapeutics plc (AIM: AGY), the fully integrated commercial biotechnology company specialising in allergy vaccines, today announces positive new data on its wholly-owned modified house-dust mite subcutaneous immunotherapy1. This data will be presented today at the 37th Annual Congress of the European Academy of Allergy and Clinical Immunology (EAACI) in Munich, Germany.
The Group’s modified house-dust mite product sold as through a Named Patient Program in Spain, is the precursor to the modified house-dust mite + MPL product currently in Phase I, as announced in February 2017.
In this observational study conducted in 10 sites across Spain, 141 patients were evaluated and demonstrated a 43% decrease in combined symptom medication score compared with baseline after one year (p = <0.0001). In addition, in a subgroup of asthmatic subjects, 16.7% of patients were observed with moderate persistent asthma at one year compared with 50.9% at baseline (p = <0.01). No patients presented with serious adverse events and no patients had to stop treatment due to any adverse event.
Allergy Therapeutics also presented a series of poster presentations at EAACI with key highlights including an overview of the early-phase pre-clinical developments for the Group’s planned recombinant peanut vaccine3 and a discussion of the results of a non-interventional study investigating rapid up-dosing of tree sublingual immunotherapy4.
Other events held by the Group at EAACI included a satellite symposium entitled: "Adjuvants through the ages"2 which provided a summary of how adjuvant technologies have evolved and how Allergy Therapeutics is spearheading the design and testing of state of the art allergen-specific immunotherapies.
Manuel Llobet, Chief Executive Officer, commented: "We are excited to be sharing our latest research at EAACI, demonstrating the breadth of our unique allergen immunotherapy company. The positive new data on our modified house-dust mite immunotherapy and our recent announcement on the success of our Grass G205 dose-finding clinical study confirms that our novel allergen-specific immunotherapies are formulated to the optimal strength, and we believe Allergy Therapeutics has the potential to transform allergy treatment with optimised-dose, well-characterised, aluminium-free, convenient products.”

About the modified mite MPL programme
House dust mite is the major cause of perennial allergic rhinitis and allergic asthma6. The modified house-dust mite + MPL product builds on the strong foundation of technologies employed in the successful Pollinex Quattro range of allergy immunotherapies. It is the only house-dust mite immunotherapy utilising MCT® (Microcrystalline Tyrosine), a natural, biodegradable depot, and the adjuvant MPL for the treatment of perennial allergic rhinitis which makes this vaccine unique in the $1.5 billion per year market7. The modified house-dust mite + MPL product is currently in phase I with an anticipated readout in Q1 2019. This is an exciting opportunity for the group to boost its addressable market.
