University of Manitoba
  Purpose
Ezetimibe has become the treatment choice for patients with sitosterolemia. Ezetimibe is an inhibitor of cholesterol absorption from the gastrointestinal tract. The purpose of this study is to determine if ezetimibe improves whole body plant sterol and cholesterol homeostasis.

Condition Intervention
Sitosterolemia Drug: Ezetimibe

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Assessment of Sterol Metabolism in Sitosterolemia: A Pilot Study of Patients Treated With Ezetimibe

Further study details as provided by University of Manitoba:

Primary Outcome Measures:
  • Plasma cholesterol level [ Time Frame: 8 months ]
    Plasma cholesterol level will be assessed by GC

  • Plasma sitosterol level [ Time Frame: 8 months ]
    Plasma plant sterol assessment using GC


Secondary Outcome Measures:
  • Cholesterol absorption [ Time Frame: 4 month ]
    Use stable isotope technique to assess cholesterol absorption

  • Cholesterol synthesis [ Time Frame: 4 months ]
    Use of stable isotope to assess cholesterol synthesis.
