A group of Israeli scientists from the Technion – Israel Institute of Technology, the Weizmann Institute of Science and Teva Pharmaceutical Industries have recently identified genes responsible for the positive response of many multiple sclerosis patients to the drug Copaxone®. These findings may contribute to the development of personalized medicine for multiple sclerosis sufferers. Copaxone® was the first original Israeli drug to be approved by the U.S. Food and Drug Administration (FDA), and is today marketed in over 40 countries worldwide, including the U.S.A., Europe, Australia, Latin America and Israel.
