Further study details as provided by Sanofi:

Primary Outcome Measures:
  • The percentage of patients with a 3-step or greater progression in the patient
  • level recoded integer ETDRS retinopathy scale

Secondary Outcome Measures:
  • The percentage of patients who:develop proliferative retinopathy or develop clinically significant macular edema
  • the distribution of patients on the patient level recoded integer ETDRS retiopathy scale
  • the change from baseline in HbA1c and fasting plasma glucose
  • the incidence of hypoglycemia

Enrollment: 1024
Study Start Date: June 2001
Study Completion Date: April 2007
Primary Completion Date: April 2007 (Final data collection date for primary outcome measure)
Detailed Description:
Randomized, open-label assignment of type 2 patients who are on a stable antidiabetic regimen to treatment with either insulin glargine or BID NPH human insulin, with baseline diabetic retinopathy of severity 53/<53 on the ETDRS scale, for 5 years of followup. Outcomes measured by seven-field fundus photography at baseline, 1.5, 3,6,and 9 months, and annually.

Ages Eligible for Study:   30 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • type 2 diabetes mellitus for at least 1 year
  • treated with oral antidiabetic agents or insulin at stable doses for at least 3 months
  • HbA1c between 6 and 12% inclusive
  • baseline retinopathy severity not to exceed 53/<53 on the ETDRS scale
  • unlikely to require laser surgery or vitrectomy within upcoming year

Exclusion Criteria:

  • prior treatment with insulin glargine
  • treatment with insulin analogs (eg insulin lispro or aspart) in the year prior to enrollment
