Clinical study to asses whether the treatment with the drug imeglimin in combination with the drug sitagliptin in treatment of adult-onset sugar diabetes is safe and more effective than treatment with sitagliptin alone. The treatments will be assigned randomly and neither the patients nor their doctor will know what treatment is given, as those who will receive sitagliptin alone, for masking purposes, will also be given placebo - dummy tablets that look just like imeglimin.
