Trial Outcomes & Findings for Antidiabetic Effects of Adding a DPP-4 Inhibitor to Pre-Existing Treatment With an Incretin Mimetic in Patients With T2D (NCT NCT01937598)

NCT ID: NCT01937598

Last Updated: 2017-01-30

Results Overview

Incremental area under the plasma glucose (BG) concentration-time profile (AUC) immediately before to 300 min after a mixed meal test. In addition, the time course of BG values will be analysed with an ANCOVA model for repeated measurements with placebo baseline values as covariate. Time points to create the curce were 0, 15, 30, 45, 60, 90, 120, 150, 180, 240 and 300 minutes post mixed meal test.

n=16 Participants
Substance: Sitagliptin phosphate H2O Pharmaceutical form: tablets Source: MSD SHARP \& DOHME GMBH, Doses: 100 mg, Route of administration: p.o. as a tablet Sitagliptin Mixed meal test: Subjects will be instructed to consume the mixed meal test within 20 minutes. The exact start and stop time of the mixed meal test consumption will be recorded in the CRF(case report form). The mixed meal test procedures will be identical for all subjects randomised in the study. To detect the plasma glucose excursion after mixed meal test, plasma glucose will be closely monitored Liraglutide: Patients on metformin monotherapy will, after screening and randomization, enter a run-in period of 2 weeks with the additional treatment of liraglutide (0.6 mg/d for 1 week followed by 1.2 mg/d for another week) that will be continued for the entire duration of the study.
