A single blind, multicenter, randomized controlled trial to evaluate the effectiveness and cost of a novel nutraceutical (LopiGLIK ® ) lowering cardiovascular disease risk.
Context: Cardiovascular disease (CVD) costs the economy €210 billion per year in Europe. There is an association between low-density lipoprotein cholesterol (LDL-C) and CVD risk.
Objective: To evaluate the cost and effectiveness of LopiGLIK® (LOPI) in lowering LDL-C and CVD risk.
Design: Single blind multicenter randomized controlled trial; patients were divided into two groups, subjected to centralized randomization.
Setting: Four Italian regions.
Participants: Thirty-one physicians enrolled 573 adult patients with mild hypercholesterolemia between January 2016 and January 2018.
Intervention: Patients were treated for 16 weeks either with LOPI (intervention) or Armolipid Plus® (AP; control).
Outcome measures: Primary outcome: percentage of patients who achieved LDL-C <130 mg/dL. Secondary outcomes: reduction of HbA1c, survival analysis and HR linked to 38.67 mg/dL reduction of LDL-C and 1% reduction of HbA1c. Costs were assessed per unit and cure.
Results: Three hundred and seventy patients treated with LOPI and 203 treated with AP were randomized and completed the study. At baseline 8.9% (n=18) patients treated with AP and 9.5% (n=35) treated with LOPI had LDL-C levels <130 mg/dL ( P =0.815). At the 16-week follow-up, 41.4% (n=84) of patients treated with AP and 67.6% (n=250) with LOPI achieved LDL-C levels <130 mg/dL ( P <0.001). LOPI patients were three times more likely to achieve LDL-C levels <130 mg/dL; adjusted OR 2.97 (95% CI; 2.08-4.24; P <0.001), number needed to treat was four (95% CI; 5.60-2.90; P <0.001). Survival analysis demonstrated the superiority of LOPI vs AP relative to 38.67 mg/dL LDL-C reduction ( P <0.002); HR was 0.761 (95% CI; 0.62-0.94; P <0.001). Both products reduced the HbA1c without a significant difference between them ( P =0.156). Survival analysis and HR (0.91; 95% CI; 0.70-1.18) estimated for 1% HbA1c reduction, showed differences between LOPI and AP, which were not significant ( P =0.411; P =0.464). The cost of LOPI was €2.11 (unit), €211 (cure), and AP €3.77 and €377, respectively.
Conclusion: LOPI appeared more effective and less expensive than AP in lowering LDL-C and CVD risk.
