Sanofi-Synthélabo has referred
to the French stock market regulatory authorities (COB)
following a financial analyst’s report concerning
one of the company’s compounds in development

Sanofi-Synthélabo has referred to the French stock market regulatory authorities, the Commission des Opérations de Bourse (COB – equivalent to the U.S. Securities and Exchange Commission), following the publication of a financial analyst report issued yesterday by Dresdner Kleinwort Wasserstein, which subsequently appeared in the press.

In this report, which claims as its source an article from a scientific journal (FASEB), published this summer, it is stated that a product in clinical development, SR141716A (rimonabant), could have a potentially carcinogenic activity.

However, this article from the scientific journal in no way evokes a carcinogenic activity for this product. On the contrary, it even indicates that, in high concentrations in vitro, the product could potentially inhibit cellular proliferation.

Given the totally misleading character of these comments, Sanofi-Synthélabo reserves all its legal rights.
