E.2.1 | Main objective of the trial |
After 24 weeks, to assess the effect of the addition of sitagliptin compared with the addition of dapagliflozin on A1C and the overall safety and tolerability of sitagliptin in comparison to that of dapagliflozin. |
Después de 24 semanas, evaluar el efecto sobre la A1C de la adición de sitagliptina en comparación con la adición de dapagliflozina y evaluar la seguridad y la tolerabilidad globales de sitagliptina en comparación con las de dapagliflozina. |
|
E.2.2 | Secondary objectives of the trial |
After 24 weeks, to assess the effect of the addition of sitagliptin compared with the addition of dapagliflozin on change from baseline in 2-hr incremental post-prandial glucose excursion and change from baseline in 2-hr post-prandial glucose. To assess, in a subset of subjects, the effect of the addition of sitagliptin compared with that of dapagliflozin on change from baseline in post-prandial insulin AUC, glucagon AUC, and insulin AUC: glucagon AUC ratio. To assess the effect of the addition of sitagliptin compared with that of dapagliflozin on the proportion of subjects at the A1C goal of <7%. To describe the effect of the addition of sitagliptin compared with that of dapagliflozin on change in fasting plasma glucose (FPG) from baseline. |
Evaluar el efecto de la adición de sitagliptina en comparación con la adición de dapagliflozina sobre la variación respecto al momento basal de la fluctuación incremental de la glucemia posprandial a las 2 horas y variación respecto al momento basal de la glucemia posprandial (GPP) a las 2 horas.Evaluar, en un subgrupo de sujetos, el efecto de la adición de sitagliptina en comparación con la adición de dapagliflozina sobre la variación respecto al momento basal del AUC de la insulina, el AUC del glucagón y la relación entre la AUC de la insulina y la AUC del glucagón postprandiales.Evaluar el efecto de la adición de sitagliptina en comparación con la adición de dapagliflozina sobre el porcentaje de sujetos que cumplen el objetivo de A1C de <7,0%.Describir el efecto de la adición de sitagliptina en comparación con la adición de dapagliflozina sobre la variación de la glucemia en ayunas (GA) con respecto al momento basal. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Merck will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time. |
Merck llevará a cabo investigaciones biomédicas futuras con las muestras obtenidas específicamente con estos fines durante este ensayo clínico.Estas investigaciones tendrán por objeto el análisis de biomarcadores para abordar aspectos nuevos que no se describen en otras partes del protocolo (como parte del ensayo principal) y solo se llevarán a cabo en muestras de los sujetos que hayan otorgado el consentimiento correspondiente. El objetivo de la obtención de muestras para investigaciones biomédicas futuras consiste en estudiar e identificar biomarcadores que proporcionen información a los científicos sobre las enfermedades y sus tratamientos. El objetivo último es utilizar tal información para desarrollar vacunas y fármacos más seguros y eficaces o para garantizar que los pacientes reciban la dosis correcta del fármaco o la vacuna adecuados en el momento preciso. |
