Lorcaserin may potentially increase the risk of cancer, according to results from a clinical trial assessing the safety of the weight loss agent.

Lorcaserin, a serotonin 2C receptor agonist, is currently indicated as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial BMI of ≥30kg/m2 or ≥27kg/m2 in the presence of at least 1 weight-related comorbidity (eg, hypertension, dyslipidemia, type 2 diabetes). It is marketed under the brand names Belviq and Belviq XR.

Data obtained from a large postmarketing study conducted in roughly 12,000 patients found that the weight loss treatment was linked to a potential cancer signal. According to a drug safety communication issued by the Food and Drug Administration (FDA), over a 5-year follow-up period, a greater proportion of patients taking the drug had been diagnosed with cancer compared with those who received placebo.
