Brief Summary:
The researchers are doing this study to see if semaglutide can slow down the growth and worsening of chronic kidney disease in people with type 2 diabetes. Participants will get semaglutide (active medicine) or placebo ('dummy medicine'). This is known as participants' study medicine - which treatment participants get is decided by chance. Semaglutide is a medicine, doctors can prescribe in some countries for the treatment of type 2 diabetes. Participants will get the study medicine in a pen. Participants will use the pen to inject the medicine in a skin fold once a week. The study will close when there is enough information collected to show clear result of the study. The total time participants will be in this study is about 3 to 5 years, but it could be longer.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Semaglutide
Participants are to receive semglutide for up to 5 years or more (event driven). The trial is event driven with a pre-defined minimum number of renal endpoint events for the primary endpoint.
 Drug: Semaglutide
Participants are to inject semaglutide with a needle in the stomach, thigh or upper arm. Participants will use a pen to inject semaglutide under their skin. Participants will inject semaglutide 1 time a week on the same day of the week. Participants' dose of semaglutide will be changed over time. Participants start by taking a smaller amount (0.25 mg). After 4 weeks the dose will be increased to 0.5 mg. It will be increased more (to 1 mg) at 8 weeks. Participants will then stay on the same dose for the rest of the study.
Placebo Comparator: Placebo
Participants are to receive placebo (semglutide) for up to 5 years or more (event driven). The trial is event driven with a pre-defined minimum number of renal endpoint events for the primary endpoint.
 Drug: Placebo (semaglutide)
Participants are to inject placebo (semaglutide) with a needle in the stomach, thigh or upper arm. Participants will use a pen to inject placebo (semaglutide) under their skin. Participants will inject placebo (semaglutide) 1 time a week on the same day of the week. Participants' dose of placebo (semaglutide) will be changed over time. Participants start by taking a smaller amount (0.25 mg). After 4 weeks the dose will be increased to 0.5 mg. It will be increased more (to 1 mg) at 8 weeks. Participants will then stay on the same dose for the rest of the study.


Outcome Measures
Go to

Primary Outcome Measures :
  1. Time to first occurrence of a composite primary outcome event defined as persistent eGFR decline of greater than or equal to 50 percentage from trial start, reaching ESRD, death from kidney disease or death from cardiovascular disease [ Time Frame: Week 0 to month 61 ]
    Measured in month(s). End Stage Renal Disease (ESRD) is defined as the following individual components: Persistent estimated glomerular filtration rate (eGFR) less than 15 mL/min/1.73m^2 or, Chronic dialysis treatment or receiving a kidney transplantation.


Secondary Outcome Measures :
  1. Annual rate of change in eGFR (chronic kidney disease - epidemiology collaboration (CKD-EPI)) (total eGFR slope) [ Time Frame: Week 0 to month 61 ]
    Measured in (mL/min/1.73 m^2)/year.

  2. Time to first occurrence of a composite cardiovascular major adverse cardiovascular event (MACE) endpoint consisting of: Non-fatal myocardial infarction, non-fatal stroke, and cardiovascular (CV) death [ Time Frame: Week 0 to month 61 ]
    Measured in month(s).

  3. Time to occurrence of all-cause death [ Time Frame: Week 0 to month 61 ]
    Measured in month(s).

  4. Time to occurrence of each of the individual components of the primary composite endpoint and of the confirmatory secondary MACE endpoint [ Time Frame: Week 0 to month 61 ]
    Measured in month(s).

  5. Time to first occurrence of major adverse limb events (MALE), a composite endpoint consisting of: Acute limb ischemia hospitalisation and chronic limb ischemia hospitalisation [ Time Frame: Week 0 to month 61 ]
    Measured in month(s).

  6. Annual rate of change in eGFR (CKD-EPI) (chronic eGFR slope) [ Time Frame: Week 12 to month 61 ]
    Measured in (mL/min/1.73 m^2)/year.

  7. Change in eGFR (CKD-EPI) [ Time Frame: Week 0, Week 12 ]
    Measured in mL/min/1.73 m^2.

  8. Change in eGFR (cystatin C CKD-EPI) [ Time Frame: Week 0, Year 3 ]
    Measured in mL/min/1.73 m^2.

  9. Relative change in urinary albumin-to-creatinine ratio (UACR) [ Time Frame: Week 0, Year 3 ]
    Measured in percentage.

  10. Change in body weight [ Time Frame: Week 0, Year 3 ]
    Measured in kilogram.

  11. Change in glycosylated haemoglobin (HbA1c) [ Time Frame: Week 0, Year 3 ]
    Measured in percentage point.

  12. Change in systolic blood pressure [ Time Frame: Week 0, Year 3 ]
    Measured in mmHg.

  13. Change in diastolic blood pressure [ Time Frame: Week 0, Year 3 ]
    Measured in mmHg.

  14. Number of severe hypoglycaemic episodes [ Time Frame: Week 0 to month 61 ]
    Number of events.
