Title: Evaluation of Diabetic Retinopathy Progression in Subjects With Type 2 Diabetes Mellitus Treated With Insulin
Brief Summary: To compare the progression of diabetic retinopathy in type 2 diabetic patients with mild-to-moderate diabetic retinopathy treated with insulin glargine vs NPH human insulin.


Options:
A: Inclusion Criteria:

* Male or female, age 18-75
* Type 2 diabetes diagnosed for at least 1 year
* Treatment with stable doses of oral agents (alone or in combination) for at least 2 months
* Inadequate glycemic control (hemoglobin A1c ≥ 7.5%) on maximum-tolerated doses of a sulfonylurea, metformin and a thiazolidinedione
* No past history of chronic insulin use (other than treatment of gestational diabetes or hospitalizations of less than 1 week in duration)
* Hemoglobin A1c between 7.5% and 12%
* Body mass index (BMI) between 20 and 40 kg/m2

Exclusion Criteria:

* Current or previous chronic use of insulin (other than for treatment of gestational diabetes)
* History of confirmed (or clinical suspicion of) type 1 diabetes
* Female subjects of childbearing potential who are sexually active and not using a reliable form of contraception
* Current pregnancy or lactation.
* Subjects for whom insulin therapy is contraindicated or for whom, in the opinion of the investigator, therapy with insulin is not indicated
* Subjects with advanced proliferative diabetic retinopathy
* Subjects who work night shifts or who are unable to stay on a consistent daily meal schedule
* History of any clinically significant renal, hepatic, cardiovascular, neurological, endocrinological or other major systemic disease that, in the opinion of the investigator, may make implementation of the protocol or interpretation of the data difficult.
* Subjects who will likely require or initiate therapy with drugs which may interfere with glucose metabolism during the course of the study
* Subjects who are in another investigational study or have received another investigational medication within 30 days of study entry
* Subjects who are unable or unwilling to comply with all components of the study protocol, including contacting the investigators at specified times and attending all scheduled follow-up visits.
B: Inclusion Criteria:

* Patients with type 2 diabetes mellitus and chronic kidney disease secondary to diabetic nephropathy in stages 3 and 4 (moderate and severe nephropathy, corresponding to glomerular filtration rate of 15-59 ml/min/1.73m²) will be included in the study.

Exclusion Criteria:

* Patients with systemic neoplasias,
* HIV, chronic kidney disease or nephropathy from other etiologies,
* severe psychiatric disorders
* pregnant women.
C: Inclusion Criteria:

* Patients with type 2 DM who are no longer responsive to maximum dose of one or more oral agents.

Exclusion Criteria:

* Angina pectoris, Canadian Class I-II,
* congestive heart failure, Class III-IV,
* stroke, incapacitating or in last 6 months,
* Myocardial infarction (MI) or invasive cardiovascular procedure within the past six months,
* ongoing diabetic gangrene,

* recurrent seizures within the past year,
* hypopituitarism,
* pregnancy, lactation, or planning a pregnancy,
* active psychosis or substance abuse,
* lack of access to a person who can assist or be called in an emergency,
* underlying conditions that in the site PI's judgment may prevent adherence to protocol,
* current participation in another clinical trial
D: 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

Answer: D
