LONDON -(Dow Jones)- Sanofi-Aventis SA (SNY) has launched a legal action against Canadian generic drugmaker Apotex Inc., which is planning to sell a low-cost version of cancer drug Taxotere in the U.S., a spokesman for the French pharmaceutical company said Tuesday. In a lawsuit filed Aug. 8, Sanofi-Aventis claimed that Apotex has infringed two U.S. patents of the drug, which in 2007 reported sales of EUR1.87 billion and is Sanofi-Aventis' fourth best-selling product.
Taxotere is used to treat breast, lung and prostate cancer.
