The drug, ladostigil, is a molecule that combines components from the existing drugs Azilect and Exelon. Teva's Azilect, for the treatment of Parkinson's disease, was developed by Prof. Emeritus Moussa Youdim of the Technion-Israel Institute of Technology. Azilect is the only anti-Parkinson's drug that has proven to have a disease-modifying effect. Novartis's Exelon was developed by Prof. Marta Weinstock-Rosin of Hebrew University to treat Alzheimer's disease.
