Main study parameters/endpoints: Primary outcomes will be measured after 3, 6, and 12 months, and include waist circumference, plasma glucose, HbA1C and the use of rimonabant.
Achtergrond van het onderzoek
Rationale:
Despite therapeutic advances, cardio metabolic disease still remains an important cause of death worldwide. The endocannabinoid system seems to be a new target for multiple risk factor management as it modulates food intake and adipogenesis. Selectively blocking the cannabinoid CB1 receptor with rimonabant has been shown to improve waist circumference, HDL-cholesterol, triglycerides and insulin resistance.
Objective:
The primary objective is to assess the (cost)-effectiveness of reimbursing rimonabant plus lifestyle counselling (combination of dietary and exercise advise) on the use of rimonabant. Secondary, we will assess the safety and effectiveness of rimonabant when used in daily practice.
Study design:
Study arm A is a single blind randomized trial with randomization on general practice level. Study arm B is a double blind randomized placebo-controlled trial in which randomization is performed on patient level.
Nature and extent of the burden, risks and benefits associated with participation:
Participants selected for this study have multiple risk factors that could result in vascular disease. Participants in this study have the opportunity to reduce their risk and improve their health. The risk associated with this study concern taking venous blood for 4 times and experiencing transient side effects from the use of rimonabant (nausea +8% compared to placebo, diarrhoea +4% and dizziness +4%).
Doel van het onderzoek
In the RIO study programme, the efficacy of rimonabant was examined. The next step is to assess the use of rimonabant, its safety and effectiveness in daily practice. In daily practice people also have other diseases, may use other medication and may be less compliant to use rimonabant than in the studies performed in research centres. All these factors could influence the use and effect of rimonabant on cardiometabolic risk reduction and therefore need to be assessed.
Onderzoeksproduct en/of interventie
Participants in the different study groups receive no medication, rimonabant or placebo plus 3 life style counseling sessions
