The effect of once daily dosing of oral Semaglutide versus once daily dosing Sitagliptin on glycemic control, body weight, and safety and tolerability will be compared in Liver Transplant Recipients with poorly-controlled Diabetes Mellitus.
This will be a Phase IV, randomized, parallel, active-controlled, double-blind clinical trial, with one group receiving oral Semaglutide and the other group receiving oral sitagliptin, while continuing any background glucose-lowering medications such as metformin or insulin. Treatment duration will be 26 weeks. Sitagliptin has been chosen as comparator since it is an established oral antidiabetic drug (OAD) within the DPP-4i drug class. There will be a screening period, treatment period, and follow-up period. Furthermore, the investigators will collect biological samples and correlates including serum, plasma, and Intestinal Microbiome samples prior to initiation of study treatment and at the completion of the trial. The investigators will also perform Transient Elastography at these same visits to evaluate change in degree of participant graft steatosis.

For purposes of clarification, patients on stable treatment with one of the following insulin regimens (minimum 10 IU/day) ≥ 90 days prior to the day of screening, may be included (maximum 20% change in total daily dose within the 90 days is acceptable):
Being on insulin, metformin, and/or an SGLT-2 inhibitor is optional.
Exclusion Criteria:
In the Semaglutide Arm, participants will receive daily: 1 tablet of Semaglutide and 1 tablet of Sitagliptin placebo for 26 weeks. The dosages of Semaglutide are 3 mg, 7 mg, and 14 mg.
Drug: Semaglutide Treatment
In the Sitagliptin arm, participants will receive daily: 1 tablet of 100 mg Sitagliptin and 1 tablet of Semaglutide placebo for 26 weeks.
Drug: Sitagliptin 100mg
The participants will be provided with Semaglutide, titrated up to 14 mg. The starting dose of Semaglutide is 3 mg once daily. At week 4, the dose will be increased to 7 mg once daily. At week 8, the dose will be increased to 14 mg once daily and will be maintained at 14mg until End of Treatment (week 26). Throughout the 26 week treatment period, participants in this arm will also take one "sitagliptin placebo" tablet per day.
participants will take 100mg tablet of Sitagliptin once daily, along with a "semaglutide placebo" pill for the duration of the 26 week treatment period
