Glaxo Diabetes Drug Shows Gastrointestinal Side Effects

GlaxoSmithKline Plc’s experimental diabetes medicine albiglutide lowered blood sugar better than Merck & Co.’s Januvia or Sanofi’s Amaryl, while more patients reported gastrointestinal side effects, in a study.

About 10 percent of patients taking albiglutide reported nausea, compared with 7 percent of those taking Januvia and 6 percent on Amaryl, according to an summary of the 104-week study dubbed Harmony 3 to be presented tomorrow at the American Diabetes Association’s annual meeting in Chicago. Vomiting and diarrhea were also more frequent among those taking albiglutide, the abstract said. All patients took the drugs with metformin.
