It was mentioned today as a company that might benefit from the news DNA released today....in that they have a similar drug currently in development? Regeneron shares ride Genentech stock surge Monday May 19, 4:26 pm ET (Updates with closing stock prices) NEW YORK, May 19 (Reuters) - Regeneron Pharmaceuticals Inc. (NasdaqNM:REGN - News) shares climbed more than 40 percent on Monday as they road the coattails of Genentech Inc. (NYSE:DNA - News), which reported positive news for an experimental cancer drug similar to one Regeneron is developing, an analyst said. Genentech on Monday said data from a late-stage trial of its experimental colon cancer drug, Avastin, showed it extends life far longer than had been expected. Genentech's stock climbed nearly 45 percent on the news. Avastin slows tumor growth by cutting off its supply of blood and oxygen. Regeneron's cancer drug, known as VEGF Trap, while in a much earlier stage of clinical trials, uses a similar mechanism to fight tumors. Regeneron, also announced some moderately positive news for its experimental obesity drug at a weekend meeting. The Tarrytown, New York-based company said a late-stage trial of its obesity drug, Axokine, identified patients most likely to benefit from the drug. But average weight loss of patients was modest and limited by patients who developed a resistance to it, Regeneron said. SG Cowen Securities analyst Yaron Werber said both the Genentech and Axokine news were likely factors in Monday's Regeneron stock surge. "It's probably related more to VEGF Trap," Werber said, calling it a promising drug.He said he believed the Regeneron drug is more potent than Genentech's. Shares of Regeneron closed up $2.93, or 41.5 percent, at $9.99 on Nasdaq, where it was among the day's top percentage gainers. ********** Thanks!
