Brief Summary

Diabetic nephropathy (DN) is one of the most frequent microvascular complications of diabetes mellitus, affecting 25 to 40% of patients with type 1 diabetes (T1DM). Early diagnosis, appropriate patient follow-up and treatment are essential to improve the outcomes. There is a need for improvements in insulin therapy for people with T1DM as the majority of patients are struggling to achieve glycemic targets. Technological advancements and oral adjuncts to insulin therapies are starting to be licensed for the use of people with T1DM. Dipeptidyl peptidase-4 (DPP-4), a multifunctional serine protease with a dual function (regulatory protease and binding protein), can modulate inflammation and immune cell-mediated β-cell destruction. DPP-4 degrades the peptide hormones glucagon-like peptide 1 (GLP-1) and gastric inhibitory peptide (GIP). Several studies have suggested that the upregulated DPP-4 activity is correlated with T1DM pathophysiology.

Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • T1DM patients aged 12-18 years with at least 5 years disease duration defined according to the criteria of International Society for Pediatric and Adolescent Diabetes (ISPAD) .
  • Patients on insulin pump therapy using Medtronic advanced hybrid closed system (Medtronic, Northridge, USA) with Guardian™ 3 sensor or Guardian™ 4 sensor and Guardian link transmitter initiated at least 6 months before the study, patients with minimum daily insulin requirement of more than 8 units, willingness and ability to adhere to the study protocol, and access to the internet as well as a computer system that met requirements for uploading the study pump data.
  • Active diabetic nephropathy in the form of microalbuminuria (urinary albumin excretion ) 30-299 mg/g creatinine in two of three samples over a 3- to 6-months period despite angiotensin converting enzyme inhibitors).
  • Hemoglobin A1c (HbA1c) ≤8.5%.
  • Patients on regular visits to clinic.

You may not qualify if:

  • patients with other diabetic microvascular complications (neuropathy or retinopathy) or with macrovascular complications.
  • Patients with history of liver disease or any disorder likely to impair liver functions or elevated liver enzymes.
  • Patients with any evidence of renal impairment due to causes other than diabetes.
  • Patients with hypertension.
  • Hepatitis virus infection (B or C) or any evidence of infection
  • Participation in a previous investigational drug study within 3 months preceding screening.
  • Hypoglycemic unawareness or recurrent severe hypoglycemic episodes in the last 6 months prior to recruitment.
  • Recurrent diabetic ketoacidosis (DKA) (more than 2 episodes in the previous 6 months).
  • Taking other oral hypoglycemic medications which could affect blood glucose.
  • Patients with known allergy to sitagliptin.
