  • Title: Double-blind comparison of bezafibrate versus placebo in male volunteers with hyperlipoproteinemia.
    Author: Bradford RH, Goldberg AC, Schonfeld G, Knopp RH.
    Journal: Atherosclerosis; 1992 Jan; 92(1):31-40. PubMed ID: 1575820.
    Abstract:
    The efficacy and safety of bezafibrate were evaluated in 83 patients with type IIa, IIb, or IV hyperlipoproteinemia. Following a 12- to 14-week placebo period on a coronary-prudent diet (Period 1), patients were assigned randomly to receive either bezafibrate 600 mg/day or placebo, plus diet in a double-blind, 12-week treatment period (Period 2). The return of lipid and lipoprotein levels toward baseline was evaluated in a subsequent 8-week period on placebo plus diet (Period 3). In patients with type IIa hyperlipoproteinemia, bezafibrate significantly lowered total (14.6%, P less than 0.001) and LDL-cholesterol (16.4%, P less than 0.001) and total (29.9%, P less than 0.001) and VLDL-triglyceride (44.0%, P less than 0.001) and significantly increased HDL cholesterol (9.5%, P less than 0.001). In patients with type IIb, bezafibrate had a qualitatively similar effect to that seen in type IIa on each of these lipoproteins, but the sample size was too small for statistical evaluation. In patients with type IV, bezafibrate lowered total (48.3%, P less than 0.01) and VLDL-triglyceride (57.7%, P less than 0.001) and VLDL-cholesterol (56.8%, P less than 0.001) and increased HDL-cholesterol (16.6%, P less than 0.05). All values returned toward baseline during Period 3. Only two bezafibrate patients experienced adverse events that were considered definitely treatment related; one was dropped from the study because of elevations in SGOT and SGPT, 1.5- and 4-times the upper limit of normal, respectively. For other laboratory parameters, trends upward or downward were small and of doubtful clinical significance. Bezafibrate appears to be effective and safe for modifying lipid and lipoprotein levels in patients with types IIa, IIb and IV hyperlipoproteinemia.
