NEW YORK/WASHINGTON (Reuters) - The U.S. Food and Drug Administration on Wednesday cast doubt on recent studies that suggested possible cancer risk with Sanofi-Aventis' widely used Lantus diabetes drug, boosting investor confidence in the blockbuster product....
In a communication posted on its website, the agency questioned four recently published studies over the cancer link, saying they did not track patients long enough to properly evaluate any such risk from the drug.
Additionally, the FDA said, "inconsistencies in findings within and across individual studies raise concerns as to whether an association between the use of (Lantus) and cancer truly exists."
It added that there may be differences in the patients studied that could have contributed to the studies' findings.
