2001: Merck Files Patent Application for a New Version of Vioxx that Would Not Harm Heart

Merck files a patent application with the US Patent Office for a drug that would contain a combination of Vioxx and an anti-clotting agent, or thromboxane inhibitor. The new drug would hopefully reduce the risk of cardiovascular problems while preserving Vioxx’s gastrointestinal benefits. Merck never develops the drug. Critics later note that Merck’s interest in this new drug contradicted its assertions that Vioxx was safe for the heart. [Associated Press, 6/22/2005]
