  Purpose
The purpose of the study is to establish the safety of ezetimibe/simvastatin and simvastatin in adolescents with Type 1 Diabetes and to determine the amount of decrease in LDL-cholesterol.The study hypothesizes that simvastatin and ezetimibe/simvastatin will be safe in adolescents with Type 1 Diabetes and will lower LDL-cholesterol at 6 months.

Primary Outcome Measures:
  • Change in LDL-c From Baseline to 6 Months in Subjects With Type 1 Diabetes Taking Vytorin or Zocor. [ Time Frame: Baseline to 6 months ]
    Change in LDL-c between Zocor and Vytorin treatment in subjects with Type 1 Diabetes measured at baseline to the 6-month study visit.


Secondary Outcome Measures:
  • No Secondary Outcomes [ Time Frame: 6 months ]
    No secondary outcomes were measured as recruitment was insufficient and study was stopped after only 9 subjects completed trial.


Enrollment: 9
Study Start Date: May 2007
Study Completion Date: August 2010
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)

Drug: Simvastatin
simvastatin 20 mg daily
Other Name: Zocor
Active Comparator: Ezetimibe/Simvastatin
Vytorin(simvastatin [Zocor} + ezetimibe [Zetia])(20 mg)daily for 6 months along with placebo (sugar pill)of comparator (Vytorin [simvastatin]).

Other Name: Vytorin

Detailed Description:
Cardiovascular disease is the leading cause of death in people with type 1 diabetes mellitus (T1DM) and since atherosclerosis begins in childhood, data to inform clinicians as to appropriate dyslipidemia treatment in this high-risk population are of great public health importance. In this trial of lipid-lowering medications (Zocor [simvastatin], a statin, compared to Vytorin [ezetimibe/simvastatin], a combination of a statin and Zetia, a medication that blocks cholesterol absorption) will be performed in patients ages 12-18 years with LDL ≥ 130 mg/dl, consistent with current ADA guidelines. The study hypothesizes that Zocor and Vytorin will be safe in adolescents with T1DM and will lower LDL-cholesterol at 6 months compared to baseline. In a two-arm design, Vytorin will lower LDL-c more than monotherapy with Zocor.
