Sanofi-Aventis SA halts clinical trial

Sanofi-Aventis SA halted all clinical trials involving Acomplia, an obesity medicine after authorities in several countries requested them to stop the trials. According to Bloomberg, this comes after European regulators stated last month that the drug was too dangerous for sale. The trials were global, including 500 patients in France. According to FierceBiotech, patients who were taking the medicine experienced a doubled risk of psychiatric disorders.
