GlaxoSmithKline Plc (GSK) will reveal detailed results today on an experimental treatment for diabetes that’s part of the reason for a $2.6 billion hostile takeover bid for Human Genome Sciences Inc. (HGSI), its partner on the drug. Glaxo will present data from two of eight late-stage studies, dubbed Harmony 6 and Harmony 7, of the once-weekly drug albiglutide ahead of the American Diabetes Association’s annual meeting next month. Abstracts of those studies will be posted on the ADA website today.
