Vienna (Austria), 16. July 2008. In the clinical phase I trial AFF001, AFFiRiS GmbH has now recruited the 24 Alzheimer patients planned for this trial. The trial aims to investigate the tolerability and safety of an innovative Alzheimer's vaccine (AFFITOPE AD01). In the trial, all patients have now been vaccinated at least once and have so far tolerated the vaccine extremely well. The treatment provides for four vaccinations administered at monthly intervals and is due to be fully completed by this October. The vaccine's tolerability can then be conclusively evaluated. So far the results indicate good tolerability for this Alzheimer's vaccine from AFFiRiS GmbH. It is on this basis that recruitment of further patients has already begun for the clinical trial of a second Alzheimer's vaccine by AFFiRiS.
