Physical examination is to be performed at visit 2 (inclusion), visit 9 (week 26), visit 11 (week 43), and visit 16 (week 69). Education on Dexcom G4 system will be performed at start visit, week 2, and week 4 in each period. Knowledge on how to perform SMBG will be checked and education will be performed if judged clinically indicated. At randomization and week 43, basic knowledge of insulin dosing will be checked and, if necessary, patients will be educated about basic insulin dosing. At visit week 13 and week 26 (and corresponding to week 56 and week 69) participants using CGM will be asked how frequently they look at the receiver screen.
