Study: NCT04196231

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: IDegLira
Description: IDegLira will be started at 16 dose steps (16 U insulin degludec plus 0.58 mg liraglutide, once daily). On the basis of prebreakfast self-monitored blood glucose measurements doses of IDegLira will be titrated individually twice per week to achieve a prebreakfast plasma glucose of 80-130 mg/dL by use of an algorithm (adding 2 dose steps for prebreakfast plasma glucose \>130 mg/dL; no dose change for prebreakfast plasma glucose of 80-130 mg/dL; reducing 2 dose steps for prebreakfast plasma glucose \< 80 mg/dL). The daily dose of IDegLira could be titrated to 50 dose steps (50 U insulin degludec plus 1.8 mg liraglutide).

Group type: ACTIVE_COMPARATOR
Intervention: IGlarLixi
Description: IGlarLixi will be started at 10 dose steps (10 U insulin glargine plus 5 mcg lixisenatide, once daily). On the basis of prebreakfast self-monitored blood glucose measurements, doses of IGlarLixi will be titrated individually once per week to achieve a prebreakfast plasma glucose of 80-130 mg/dL by use of an algorithm (adding 2 dose steps for prebreakfast plasma glucose \>130 mg/dL; no dose change for prebreakfast plasma glucose of 80-130 mg/dL; reducing 2 dose steps for prebreakfast plasma glucose \< 80 mg/dL). The daily dose of IGlarLixi could be titrated to 60 dose steps (60 U insulin degludec plus 20 mcg lixisenatide).

Intervention: Insulin/Canaglifozin
Description: Patients in this arm will continue the basal insulin used before the randomization, with dosage titration on the basis of the following algorithm: adding 2 units for prebreakfast plasma glucose \>130 mg/dL; no dose change for prebreakfast plasma glucose of 80-130 mg/dL; reducing 2 units for prebreakfast plasma glucose \< 80 mg/dL. Moreover, they will be assigned to canaglifozin, according to the current clinical practice and the drugs' data sheet. Canagliflozin will be started at 100 mg daily per oral administration, and augmented to 300 mg/per day if required (HbA1c \>7.5 after 12 weeks).

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: Insulin/Dapaglifozin
Description: Patients in this arm will continue the basal insulin used before the randomization, with dosage titration on the basis of the following algorithm: adding 2 units for prebreakfast plasma glucose \>130 mg/dL; no dose change for prebreakfast plasma glucose of 80-130 mg/dL; reducing 2 units for prebreakfast plasma glucose \< 80 mg/dL. Moreover, they will be assigned to dapaglifozin, according to the current clinical practice and the drugs' data sheet. Dapagliflozin will be started at 10 mg daily per oral administration

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: Insulin/Empaglifozin
Description: Patients in this arm will continue the basal insulin used before the randomization, with dosage titration on the basis of the following algorithm: adding 2 units for prebreakfast plasma glucose \>130 mg/dL; no dose change for prebreakfast plasma glucose of 80-130 mg/dL; reducing 2 units for prebreakfast plasma glucose \< 80 mg/dL. Moreover, they will be assigned to empaglifozin, according to the current clinical practice and the drugs' data sheet. Empagliflozin will be started at 10 mg daily per oral administration, and augmented to 25 mg/per day if required (HbA1c \>7.5 after 12 weeks).

Intervention type: DRUG
Group type: ACTIVE_COMPARATOR
Intervention: Basal Bolus
Description: Patients in this arm will continue the basal insulin (glargine, degludec or glargine-300) used before the randomization. The insulin titration will be guided by the medical staff, according to the following algorithm: adding 2 units of basal insulin for prebreakfast plasma glucose \>130 mg/dL; no dose change for prebreakfast plasma glucose of 80-130 mg/dL; reducing 2 units of basal insulin for prebreakfast plasma glucose \< 80 mg/dL. The short acting insulin analogue (lispro, aspart or glulisine) will be started at the dosage of 4 units before meals (3 times per day) and will be titrated twice a week until achieving pre-prandial glucose values ranging from 80-130 mg/dL.
