Allergy Therapeutics enters co-development agreement with Ergomed plc

12 December 2017 Allergy Therapeutics plc (AIM:AGY), the fully integrated specialty pharmaceutical group specialising in allergy vaccines, today announces it has entered into a co-development collaboration agreement with Ergomed plc ("Ergomed") (AIM:ERGO) for the clinical development of three OralVac immunotherapy products. Allergy Therapeutics' core focus remains the convenient short course subcutaneous immunotherapy (SCIT) products, with the OralVac sublingual products providing an alternative option for patients who prefer oral products.

To capitalise on the changing regulatory requirements in Germany, the OralVac products, which are currently sold in Europe on a named patient basis, are being registered under the new TAV (Therapieallergene-Verordnung) regulation programme managed by the Paul Ehrlich Institute in Germany. The pharmaceutical development and pre-clinical evaluation for these products has already been completed by Allergy Therapeutics.

This planned OralVac clinical development expands Allergy Therapeutics' current broad SCIT clinical programme. To manage this expansion, Simon Piggott, Head of Clinical Sciences and Denise Lee, Head of Clinical Operations will lead early and late phase EU clinical development respectively, with Pieter-Jan de Kam, Clinical Director, to lead the US clinical development programme, which is focused on SCIT products and is a key part of the Group's three-pillar growth strategy.

Under the terms of the agreement, Ergomed will progress the clinical development of OralVac products for the treatment of grass pollen, tree pollen, and house dust mite allergies. The collaboration includes a future revenue share and reduced service fee.

Manuel Llobet, CEO at Allergy Therapeutics, stated: "We are pleased to announce this co-development programme with Ergomed, which is aimed at strengthening our product portfolio across Europe in a risk-sharing fashion. Ergomed has over 20 years of experience in clinical development and significant expertise in the allergy field, and are thus ideally placed to support us in the progression of our OralVac products."
