Why were the recent studies conducted by third parties and not sanofi-aventis?
Based on the results of our research, sanofi-aventis has never had any reason to suspect a link between LANTUS® and cancer. Our own five-year follow-up study with LANTUS® did not find an increased risk of cancer. No cancer risk has been identified with LANTUS® throughout its development, so we never found cause to conduct research about a possible link.
