Lowering LDL cholesterol by statins has been proven to be associated with reduction of proinflammatory regulators e.g. activation of the transcription factor NF-ĸB. Up to now the effects of newer cholesterol lowering agents such as ezetemibe with respect to their anti-inflammatory potential are less intensively studied. Therefore the investigators analyzed whether equipotent LDL-lowering therapy with simvastatin alone and in combination with ezetimibe have comparable effects on NF-ĸB-activation in peripheral blood mononuclear cells (PBMCs) of patients with type 2 diabetes.

Condition Intervention
Type 2 Diabetes
Drug: Simvastatin 80 mg
Drug: Sim10/Eze10
Drug: Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)

Further study details as provided by Heidelberg University:

Primary Outcome Measures:
  • NF-kappa B binding activity [ Time Frame: up to 5 years ]
    The binding activity of nuclear transcription factor nuclear factor kappa B (NF-kappa B)will be measured in patients with type 2 diabetes before and after 8 weeks while under study treatment. Analysis will be done with electrophoretic mobility shift assay. Nuclear extract, which is necessary, will be generated from peripheral blood mononuclear cells.

Secondary Outcome Measures:
  • Inflammatory markers [ Time Frame: up to 5 years ]
    Blood levels of high sensitivity CRP and interleukin-6 will be measured before study start and after 8 weeks while under study medication.
