About this study

A kidney transplant is the best treatment for people living with kidney failure as it allows people to live longer with a better quality of life. However, one in four kidney transplant recipients will develop diabetes after transplant. This is largely due to the medications that must be used to prevent rejection of the transplant. Kidney transplant recipients who get diabetes after transplant are up to three times more likely to have heart disease and die prematurely. To date, there are no treatments to prevent the development of diabetes after kidney transplant. Semaglutide is a drug that is commonly used to treat diabetes and obesity. The investigators believe that semaglutide is a safe and effective drug which can prevent the development of diabetes in kidney transplant recipients. Therefore, the investigators are conducting a study where kidney transplant recipients who are at increased risk of developing diabetes after transplant are randomly assigned to receive either semaglutide or placebo for 24 weeks after their transplant. The study will determine whether semaglutide is effective in decreasing blood sugar levels and the rate of diabetes. The investigators will also study other important markers of health including body weight and cholesterol levels as well as liver, kidney and heart function. Diabetes after transplant is a common problem, and preventing it is extremely important to allowing kidney transplant recipients to live longer and better lives. The results of this study will allow the investigators to determine if semaglutide is a safe and effective option for the prevention of diabetes in kidney transplant recipients.

Primary outcomes

  1. 2-hour OGTT

    Time frame: 24 weeks

    The primary outcome of this study is the change in plasma glucose at 120 minutes following a 75g oral glucose challenge (2-hour OGTT) at 24 weeks. The 2-hour OGTT was selected as the primarily outcome in this study for the following reasons: 1) In selecting a surrogate outcome for PTDM in KTR, there are limitations to HbA1c and fasting glucose in this population; 2) The 2-hour OGTT is the recommended test for the diagnosis of PTDM in KTR and 3) The use of OGTT has been used in other PTDM prevention studies.

Secondary outcomes

  1. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]

    Time frame: 24 weeks

    : The side effects of GLP-1RA have been well described and will be assessed at each study visit. Adverse events include AKI, hypoglycemia, volume depletion, GI intolerance, amputations, pancreatitis, hepatobiliary complications and injection site or allergic reactions, infectious complications (any source), and malignancy. Episodes of biopsy-proven acute rejection (as defined by the Banff criteria), death-censored graft failure (defined as the need for initiation of chronic dialysis or re-transplantation) or death with graft function (defined as death with a functioning allograft) will also be collected. Kidney transplantation assures complete denervation of the transplanted kidney and the renal vasoconstrictive response in the setting of intravascular volume depletion is diminished in KTR. Therefore, frequent monitoring for adverse events has been integrated in our study design, occurring on 10 separate occasions, to capture these adverse events should they occur.
