Evaluation of lorcaserin on progression of prediabetes to type 2 diabetes and reversion to euglycemia.
POSTGRADUATE MEDICINE(2016)
摘要
Objectives: Lorcaserin is a selective 5-HT2C (5-hydroxytryptamine 2C) receptor agonist indicated for weight management. Here, we assess the impact of lorcaserin on progression from prediabetes to type 2 diabetes (T2D) and on reversion from prediabetes to euglycemia. Methods: This is a post hoc analysis of pooled data from two Phase 3 studies, BLOOM and BLOSSOM (N=6136), evaluating the impact of lorcaserin on weight and glycemic parameters over 52 weeks in the subpopulation of obese/overweight subjects with prediabetes, alternately defined by fasting plasma glucose (FPG) 100-125mg/dl or glycated hemoglobin (HbA1c) 5.7-6.4% at baseline. Results: At Week 52, in the subpopulation with prediabetes, nearly twice as many lorcaserin-treated subjects achieved 5% weight loss versus placebo (HbA1c: 55.6% vs. 27.5%, p<0.001; FPG: 52.8% vs. 28.8%, p<0.001), and a significantly lower percentage of lorcaserin-treated subjects progressed to T2D versus placebo based on HbA1c (lorcaserin 3.2%, placebo 5.0%, p=0.032) but not FPG (lorcaserin 1.6%, placebo 2.6%, p=0.227). A significantly greater proportion of lorcaserin-treated subjects versus placebo also reverted to euglycemia based on both HbA1c (lorcaserin 40%, placebo 29.5%, p<0.001) and FPG (lorcaserin 52.4%, placebo 46.5%, p=0.047). Conclusion: In subjects with prediabetes, lorcaserin may contribute to weight loss and improve glycemic parameters, and thus may help with preventing progression to T2D and promoting reversion to euglycemia.
