E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of the study is to investigate the efficacy, safety and tolerability of linagliptin 5 mg qd compared to placebo given for 24 weeks in inadequately controlled T2DM patients on empagliflozin 10 mg or 25 mg and maximum tolerated dose of metformin. The study is designed to show superiority of the combination of empagliflozin and linagliptin over empagliflozin alone. |
L'obiettivo dello studio e' valutare l'efficacia, la sicurezza e la tollerabilita' di linagliptin 5 mg somministrato per 24 settimane in confronto a placebo in pazienti con diabete mellito di tipo 2 non controllati adeguatamente dopo 16 settimane di trattamento con empagliflozin 10 mg o 25 mg in aggiunta alla massima dose tollerata di metformina. Il disegno dello studio e' mirato alla dimostrazione di superiorita' della combinazione di empagliflozin e linagliptin rispetto a solo empagliflozin. |
