Extension of Alzheimer's disease vaccine development collaboration

1st April 2013

AFFiRiS AG announced today significant progress in their collaboration with GlaxoSmithKline Biologicals (GSK) for the development of an active vaccination programme against Alzheimer´s disease. While the lead vaccine candidate AD02 is currently in phase II clinical testing, two additional preclinical programmes have been completed successfully. The second programme was related to alternative vaccine candidates generated by AFFiRiS´ AFFITOME technology, including candidate AD03. Based on the promising preliminary results of this programme, GSK exercised its option for the alternative vaccine candidates which triggered a EUR2.5 million payment to AFFiRiS. An additional EUR 1 million payment became due simultaneously for the successful completion of tests of alternative vaccine formulations.

AFFiRiS announced today the successful completion of preclinical work packages and related payments of EUR3.5 million from GSK to AFFiRiS. The two companies have been working together for more than two years on an active vaccination approach for the treatment of Alzheimer´s disease. The collaboration is based on a license and option agreement announced in October 2008. The deal has a total potential value of up to EUR430 million plus royalties. EUR36 million have already been paid within the framework of this collaboration.

The co-founder and CEO of AFFiRiS, Dr Walter Schmidt comments: "Our Alzheimer's vaccination programme is progressing very positively. Two vaccine candidates, AD01 and AD02, demonstrated satisfactory safety and tolerability profiles in phase I clinical trials and AD02 has already been moved forward into clinical phase II for efficacy testing. Now we have opened the pathway to alternative vaccine candidates such as AD03 and we are delighted that GSK awarded this achievement by exercising its related option. We welcome the opportunity to extend and further strengthen the collaboration between the two companies."

All three of AFFiRiS´s Alzheimer's vaccine candidates are designed to induce antibodies targeting the beta-amyloid peptide that is believed to contribute significantly to the pathology of Alzheimer's. With AD03, the third of the candidates, AFFiRiS additionally targets modified beta-amyloid peptides with their putatively different toxicity profiles in humans.

On top of its diversified activities in the Alzheimer´s field, AFFiRiS possesses a strong product pipeline including vaccine canditates for the treatment of Parkinson, Atherosclerosis, Hypertension and various other diseases. Remarkably, AFFiRiS recently announced that its preclinical program for the development of a Parkinson vaccine has been awarded with substantial funding by the US-based Michael J Fox Foundation.

The co-founder and CSO of AFFiRiS Dr Frank Mattner comments on this early and successful establishment of the strong development pipeline: "Many biotech companies strive to establish a pipeline in order to minimise risk. Sometimes their endeavours fail due to technical reasons sometimes because of financial constraints. Our AFFITOME®-Technology allows us to avoid technical challenges that are relevant to our approach. This technology also delivers a whole pool of product candidates for each of our targets rather than a single entity thereby significantly increasing our likelihood of success."
