Inclusion Criteria

  • 1\.Capable of understanding the content of and able voluntarily to provide a personally signed and dated written informed consent form.
  • 2\.Stated willingness to comply with all study procedures and availability for the duration of the study.
  • 3\.Male or female, aged 18\-70 years inclusive.
  • 4\.Clinical diagnosis of type 1 diabetes, defined as at least 2 out of 3 of the following: (i) age of onset \< 40 years, (ii) insulin commenced within 1 year of the diagnosis of diabetes, (iii) positive autoantibodies for at least 1 of the antibodies associated with type 1 diabetes (islet cell antibody \[ICA], insulin autoantibody \[IAA], tyrosine phosphatase–like insulinoma antigen\-2 autoantibody \[IA\-2A], zinc transporter 8 autoantibody (ZnT8 A) and glutamic acid decarboxylase autoantibody \[GADA]).
  • 5\.Established albuminuria, defined as an urine albumin to creatinine ratio (UACR) greater than or equal to 2\.5 mg/mmol in men or greater than or equal to 3\.5 mg/mmol in women, with
  • (a)the most recent UACR to have been within the albuminuria range and collected within the 12 months before Visit 1, AND
  • (b)at least one other UACR within the albuminuria range in the last 24 months before Visit 1, AND
  • (c)with not more than 1 normal UACR (i.e. \<2\.5 mg/mmol in men or \<3\.5 mg/mmol in women) in the 24 months before Visit 1, AND
  • (d)the geometric mean of the 2 UACR tests collected at Visit 1 is in the albuminuria range, greater or equal to 2\.5 mg/mmol in men or greater or equal to 3\.5 mg/mmol in women.
  • 6\.eGFR greater or equal to 40 mL/min/1\.73 m2, as calculated by the CKD\-EPI creat formula, at Visit 1\.

Exclusion Criteria

  • 1\.History of type 2 diabetes.
  • 2\.HbA1c at Visit 1 greater or equal to 10\.0% (greater or equal to 86 mmol/mol).
  • 3\.Chronic kidney disease due to a documented history of non\-diabetic kidney disease(s), except for hypertensive nephropathy, which is acceptable. Therefore, the chronic kidney disease must be due to diabetic kidney disease, with or without hypertensive kidney disease.
  • a.Diagnostic or interventional procedure requiring a contrast agent within 4 weeks of the first screening visit.
  • b.Untreated urinary tract infection at Visit 1 that would impact urinary protein levels.
  • c.History of renal transplant or other solid organ transplant, or planned renal transplant or other solid organ transplant during the study.
  • d.A history of acute renal dialysis or acute kidney injury (defined according to the Kidney Disease: Improving Global Outcomes \[KDIGO] definition) within 13 weeks of Visit 1\.
  • 4\.Body mass index (BMI) \<18\.5 kg/m2 or \>40 kg/m2\.
  • 5\. eGFR \<40 ml/min/1\.73m2, as calculated by the CKD\-EPI creat formula.
  • 6\.Alteration in anti\-hypertensive therapy within 13 weeks prior to Visit 1, including change in dosing with ACEI or ARB.
