Efficacy and Safety of FIAsp in a Basal-bolus Regimen Versus Basal Insulin Therapy, Both in Combination With Metformin in Adult Subjects With Type 2 Diabetes

Efficacy and Safety of FIAsp in a Basal-bolus Regimen Versus Basal Insulin Therapy, Both in Combination With Metformin in Adult Subjects With Type 2 Diabetes

This trial is conducted in Asia, Europe, South America, and the United States of America (USA).

The aim of the trial is to investigate efficacy and safety of FIAsp in a basal-bolus regimen versus basal insulin therapy, both in combination with metformin in adult subjects with type 2 diabetes.

Inclusion Criteria:

• Type 2 diabetes (diagnosed clinically) for at least 6 months prior to the screening visit (Visit 1)
• Current treatment with once daily insulin detemir, insulin glargine or human isophane insulin, NPH for at least 3 months prior to the screening visit (Visit 1)
• Current treatment with a) metformin with unchanged dosing for at least 3 months prior to screening (visit 1). The metformin dose must be at least 1000 mg or b) metformin in combination with sulfonylurea (SU) or glinide or Dipeptidyl peptidase-IV inhibitors and/or alpha-glucosidase inhibitors (AGI) with unchanged dosing for at least 3 months prior to screening (visit 1). The metformin dose must be at least 1000 mg
• HbA1c by central laboratory a) 7.5-9.5% (58 - 80 mmol/mol) (both inclusive) in the metformin group at the screening visit (Visit 1) or b) 7.5-9.0% (58 - 75 mmol/mol) (both inclusive) in the metformin + other oral antidiabetic drug (OAD) (sulphonylurea (SU), glinide, dipeptidyl peptidase-IV (DDP-IV) inhibitors, alpha-glucosidase inhibitors (AGI) combination group at the screening visit (Visit 1)
• Body mass index (BMI) equal or less than 40.0 kg/m^2

Exclusion Criteria:

• Any use of bolus insulin, except short-term use due to intermittent illness (no longer than 14 days of consecutive treatment) and not within 3 months prior to the screening visit (Visit 1)
• Use of Glucagon-like peptide-1 (GLP-1) agonists and/or Thiazolidinediones (TZD) within the last 3 months prior to screening (visit 1)
• Recurrent severe hypoglycaemia (more than one severe hypoglycaemic event during the last 12 months) or hypoglycaemic unawareness as judged by the Investigator, or hospitalisation for diabetic ketoacidosis during the previous 6 months prior to screening (Visit 1)
