WHITEHOUSE STATION, N.J.--(BUSINESS WIRE)--New data analyses presented at the 44th Annual Meeting of the European Association for the Study of Diabetes (EASD) showed initial combination therapy with the dipeptidyl peptidase-4 (DPP-4) inhibitor, JANUVIA™ (sitagliptin), and metformin provided improvements in blood sugar levels (as measured by A1C1) over two years of treatment and was generally well tolerated. Also presented at the meeting was a separate, new pooled analysis of 6,139 patients that showed that JANUVIA was generally well tolerated in clinical trials up to two years in duration.
