Sanofi ($SNY) has gotten a bit of positive reinforcement in its efforts to revive its diabetes business in the U.S. Experimental combo med LixiLan has thrown off some promising results, hitting its primary goal in a late-stage trial. The results set it up to file for FDA approval in Q4 of this year and for European approval in 2016's first quarter. Sales have been forecast to reach €770 million by 2020.
