The Phase I clinical study, in which the new Alzheimer's drug candidate PRI-002 is being tested for the first time in humans, has now officially started in Vienna. On Monday, PRI-002 was administered to the first healthy volunteer. The study will evaluate the safety and tolerability of the oral dosage form of PRI-002 in healthy volunteers.
