Teva to Terminate the Promise Trial Following Unfavorable Interim Analysis

Jerusalem, Israel, November 7, 2002 - Teva Pharmaceutical Industries Ltd. (Nasdaq: Teva) announced that an interim analysis of its clinical trial on primary progressive multiple sclerosis showed that it was improbable that the study at its current protocol, would reach statistical significance. The scheduled interim analysis by the study's data safety monitoring committee came two years into the three-year study. There have been no safety concerns about treatment with COPAXONE®(glatiramer acetate for injection).

"Primary progressive MS is very different from relapsing-remitting MS, affecting less than 10% of MS patients worldwide, and there is much we still need to learn about what causes these patients to progress. Even though this trial will not yield a drug therapy, the amount of data accumulated, will bring us a step closer to future treatments to help people with primary progressive MS." said Jerry S. Wolinsky M.D., principal investigator of the study, and director of the MS Research Group at the University of Texas Health Science Center, Houston, Texas. "What we do know is that COPAXONEreg; is an effective treatment for the relapsing form of the disease as was demonstrated in three placebo-controlled trials, and with data accumulated on long term efficacy of up to 8 years".

We are sorry that the results mean that patients with primary progressive MS will not benefit from COPAXONE® as do over 60,000 relapsing-remitting patients worldwide. However, we knew when we launched the trial that no company has yet been able to find a therapy for this severely affected patient population," said Israel Makov, President and CEO of Teva. "Our company is committed to continued research in the field of MS both with COPAXONE® and new molecules".

COPAXONE® is the second most prescribed therapy for relapsing-remitting MS in the United States and is approved in 41 countries worldwide, including the U.S., Canada, Australia, Israel and all the European countries. In Europe, COPAXONE® is marketed by Teva Pharmaceutical Industries Ltd., and Aventis Pharma. In North America, COPAXONE® is marketed by Teva Neuroscience, a fully owned subsidiary of Teva Pharmaceutical Industries.
