An Internet newsletter devoted to the anti-obesity drug Acomplia can keep its Web site address now that it has settled with the drug’s maker, Sanofi-Aventis SA.

Medical Week News Inc. launched last year to track the progress of the drug as it goes through clinic trials and awaits approval from the U.S. Food and Drug Administration. But Sanofi-Aventis asked an international arbitrator to force Medical Week to relinquish the site name, saying it could confuse the public.
