Original Research Article


Background: D-003 is a mixture of long-chain aliphatic primary acids purified from sugarcane wax with hypocholesterolaemic effects proven in rabbits and healthy volunteers; it lowers serum total cholesterol (TC) and low-density lipoprotein-cholesterol (LDL-C) and increases high-density lipoprotein-cholesterol (HDL-C). D-003 also prevents lipoprotein lipid peroxidation in experimental models.

Objective: To investigate the effects of D-003 on lipid profile and lipid peroxidation in healthy human volunteers.

Participants: Forty-six healthy volunteers (24 women, 22 men).

Methods: This double-blind, randomised, placebo-controlled study investigated the effects of D-003 at 5 and 10 mg/day on the susceptibility of LDL to lipid peroxidation induced by copper ions in healthy volunteers. Forty-six individuals were randomised (1 : 2) to placebo or D-003 at 5 or 10 mg/day, the tablets being taken once a day with the evening meal for 8 weeks. Laboratory determinations and physical examination were performed at baseline and after 4 and 8 weeks of therapy, and compliance and adverse experience assessments were performed at weeks 4 and 8.

Results: All groups were well matched at baseline. At study completion, D-003 at 5 and 10 mg/day significantly (p < 0.001) lowered LDL-C, the primary response variable, by 20.8% and 28.8%, respectively. In addition, D-003 at 5 and 10 mg/day reduced (p < 0.001) TC (12.7% and 17.5%, respectively), LDL-C/ HDL-C (25.9% and 36.3%, respectively) and TC/HDL-C (18.6% and 26.3%, respectively), while significantly (p < 0.01) increasing HDL-C (7.7% and 12.4%, respectively). Triglycerides were significantly (p < 0.05) reduced (8.8% and 13.1%, respectively) with respect to baseline, but not versus placebo. Responses assessed at 4 weeks showed significant reductions of LDL-C, TC and atherogenic ratios with both doses of D-003, whereas HDL-C was significantly increased. Triglycerides, however, remained unchanged. No significant changes in any lipid profile variable occurred in the placebo group. D-003 at 5 and 10 mg/day significantly (p < 0.05) increased lag time (18.3% and 32.0%, respectively) and decreased maximum rate of diene propagation (Vmax) [12.7% and 19.1%, respectively] of copper-induced LDL peroxidation. D-003 5 and 10 mg/day attenuated the reduction of the reactivity against 2, 4, 6-trinitrobenzene sulfonic acid (TNBS) by 19.9% and 32.0%, respectively. The treatment was well tolerated. Three subjects (one from each group) discontinued the study. Only one, treated with D-003 5 mg/day, discontinued because of an adverse event (gastritis).

Conclusions: D-003 at 5 and 10 mg/day demonstrated dose-dependent cholesterol-lowering effects in healthy volunteers characterised by reductions in LDL-C, TC and atherogenic ratios, and increases in HDL-C. Effects on triglycerides were modest and uncertain. As expected from experimental studies, D-003 inhibited the susceptibility of LDL to lipid peroxidation assessed by three indicators lag time Vmax and reactivity versus TNBS. Further studies investigating the effect of larger doses and treatment duration must be conducted to confirm the reproducibility of the present results in different study populations.
