Allergy Therapeutics announces positive top-line results from its Grass MATA MPL
Phase II dose ranging study
- Primary endpoint met with highly statistically significant dose-response relationship established -
- Optimal Phase III dose identified -
- Phase III study due to commence in 2019 -
21 May 2018 Allergy Therapeutics plc (AIM: AGY), the fully integrated commercial biotechnology company specialising in allergy vaccines, today announces highly positive top-line results from its Grass Modified Allergen Tyrosine Absorbed (MATA) MPL Phase II dose ranging study (G205). The trial met its primary endpoint of establishing a dose-response relationship and a Phase III dose. Approximately 30% of the population in Europe and 25% of the population of the US are allergic to grass pollen1, one of the most prevalent global aeroallergens.
The key results announced today:
The G205 trial is a multi-centre, double-blind, placebo controlled study designed to explore the safety and response of different cumulative doses of Grass MATA and MPL for grass-pollen induced seasonal allergic rhinitis. The European study took place in Germany, Poland and Austria and 447 patients were randomised into four active arms plus a placebo, evaluating the change in allergic symptoms as determined by the total symptom score (TSS) following conjunctival provocation test (CPT) with the objective to achieve a dose recommended for Phase III development.
Manuel Llobet, CEO at Allergy Therapeutics, stated: "We are thrilled with these extremely positive results demonstrating dose dependent efficacy of the product including the current marketed dose. This study represents a major milestone in our path forward to a registered grass allergy product in Europe. Additionally, this brings us closer towards marketing authorisation in the estimated $2bn US allergy market, a significant opportunity where our product has the potential to be the first registered subcutaneous immunotherapy for the treatment of grass allergy. With an optimal dose identified, we look forward to sharing this new, exciting data with the health authorities and plan to commence a Phase III study in 2019.
"Allergy Therapeutics provides the only ultra-short course, aluminium-free treatment containing our MPL adjuvant in the European market, and its convenience for patients is driving market penetration in all our markets."

About Grass MATA MPL
Grass MATA MPL contains three distinct components: allergoids, micro-crystalline tyrosine (MCT) and monophosphoryl lipid A (MPL®). Allergoids (natural allergens chemically modified to form allergoids) exhibit reduced allergenicity that improves safety and allows for delivery of higher doses. These are combined with the depot adjuvant technology MCT to provide enhanced immune exposure and further improved tolerability.
Finally, the immune response is enhanced and directed by the adjuvant MPL®. MPL is a toll-like 4 receptor (TLR4) agonist which has been extensively used in the Group's other allergy vaccines available on the market and in vaccines registered in the USA.
If approved, the product will be the first registered subcutaneous immunotherapy product in the US for grass allergy.
About US allergy market
The US allergy immunotherapy market, which is anticipated to be the main market for this product, is estimated by the Group to be worth $2 billion with potential peak grass vaccine sales of $300-400 million per annum.
