Introduction: Obesity contributes significantly to cardiovascular disease (CVD) risk and weight management is associated with CVD risk reduction. Lorcaserin, a selective 5HT 2C receptor agonist, is indicated as an adjunct to a reduced-calorie diet and increase physical activity for weight management in adults with obesity (BMI≥30) and overweight (BMI 27-29.9 and ≥1 weight-related comorbidity). This analysis used the Framingham 10-year CVD risk to examine the impact of lorcaserin treatment on CVD risk and risk reduction. Method: Pooled data from two randomized, double-blind studies (BLOOM & BLOSSOM) investigating the efficacy of lorcaserin vs. placebo among non-diabetic patients with overweight or obesity, were used in this analysis. Framingham CVD risk was calculated for those whose lipid values were available at baseline and at one year. A Framingham CVD risk of <5% was classified as low risk. Patients were stratified by cohort, lorcaserin (LOR) vs. placebo (PBO) and response at week 12 (≥5% weight loss vs. < 5%) for calculating the 10-year CVD risk at one year. Logistic regression was used to adjust for baseline risk and determine if proportional differences in risk reduction were significant. Results: A total of 5,658 patients were evaluated, 51% treated with LOR. Among the LOR-treated patients, 43% achieved ≥5% weight loss at week 12 (compared to 19% treated with PBO). At one year, more patients in the LOR cohort had reduced CVD risk (from high to low risk, 21% vs. 15%, respectively). The regression analysis showed LOR-treated patients were 34% more likely to have low CVD risk (p<0.001). Similarly, for patients who lost ≥5% baseline body weight at 12 weeks, more patients in the LOR cohort had reduced CVD risk (from high to low risk, 26% vs. 16% respectively) at one year. The regression showed LOR-treated patients were 23% more likely to have low CVD risk (p<0.05). Conclusion: The analysis suggests that patients treated with LOR are more likely to have low CVD risk at one year than those treated with PBO. The effect is magnified if patients have ≥5% weight loss at 12 weeks.
