Arm Description

Standard of care insulin will be used as an active comparator arm for 1/3 of patients (38 patients) for the entire duration of the study.

Once a week injection of Semaglutide (a GLP-1 receptor agonist) in addition to standard of care insulin for the first six months in 2/3 of patients (76 patients). Semaglutide is a clear, colorless solution that contains 2 mg of semaglutide in a 1.5 mL (1.34 mg/mL) pre-filled, disposable, single-patient-use pen injector. Semaglutide will be started at the 0.25 mg dose for the first two weeks, then increased to 0.5 mg at week 2, and then yet again increased to 1.0 mg at week 4.

Once a day oral pill (green, plain, diamond shaped film coated 5 mg tablet) of Dapagliflozin (an SGLT-2 inhibitor) added to once a week injection of semaglutide and standard of care insulin in the second 6 months of 1/2 of the dual therapy arm (1/3 of total patients (38 patients)). Dapagliflozin will be started at 5 mg for one week, and then increased to 10 mg for the remainder of the study

Once a day oral pill (green, plain, diamond shaped film coated 5 mg tablet) of the Placebo form of Dapagliflozin added to once a week injection of semaglutide and standard of care insulin in the second 6 months of 1/2 of the dual therapy arm (1/3 of total patients (38 patients)).
