This study has been completed.

Information provided by (Responsible Party):
The Cleveland Clinic
ClinicalTrials.gov Identifier:
NCT00432809
First received: February 6, 2007
Last updated: November 17, 2016
Last verified: February 2016
  Purpose
The aim of the study is to compare the relative clinical outcomes between advanced medical therapy alone or advanced medical therapy combined with bariatric surgery [either Roux-en-Y gastric bypass (RYGBP) or laparoscopic sleeve gastrectomy] in patients with type 2 diabetes and a body mass index (BMI) between 27 and 43 kg/m2. The study will examine the short and long term effects of each intervention on biochemical resolution of diabetes, diabetic complications, and end-organ damage.

Primary Outcome Measures:
  • Success Rate of Biochemical Resolution of Diabetes at 12 Months as Measured by HbA1c ≤ 6%. [ Time Frame: 1 year ]
    The proportion of subjects with a glycated hemoglobin level of 6% or less(with or without diabetes medications) 12 months after randomization (baseline measure).

  • Success Rate of Biochemical Resolution of Diabetes at 12 Months as Measured by HbA1c ≤ 6% With no Diabetes Medications [ Time Frame: 1 year ]
