[Efficacy and safety of Changsulin® compared with Lantus® in type 2 diabetes: a phase Ⅲ multicenter, randomized, open-label, parallel, controlled clinical trial].

Objective: To compare the efficacy and safety of Changsulin® with Lantus® in treating patients with type 2 diabetes mellitus (T2DM). Methods: This was a phase Ⅲ, multicenter, randomized, open-label, parallel-group, active-controlled clinical trial. A total of 578 participants with T2DM inadequately controlled on oral hypoglycemic agents were randomized 3∶1 to Changsulin® or Lantus® treatment for 24 weeks. The efficacy measures included changes in glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), 2h postprandial plasma glucose (2hPG), 8-point self-monitoring of blood glucose (SMBG) profiles from baseline, and proportions of subjects achieving targets of HbA1c and FPG. The safety outcomes included rates of hypoglycemia, adverse events (AEs) and anti-insulin glargine antibody. Results: After 24 weeks of treatment, mean HbAlc decreased 1.16% and 1.25%, FPG decreased 3.05 mmol/L and 2.90 mmol/L, 2hPG decreased 2.49 mmol/L and 2.38 mmol/L in Changsulin® and in Lantus®, respectively. No significant differences could be viewed in above parameters between the two groups (all P>0.05). There were also no significant differences between Changsulin® and Lantus® in 8-point SMBG profiles from baseline and proportions of subjects achieving the targets of HbA1c and FPG (all P>0.05). The rates of total hypoglycemia (38.00% and 39.01% for Changsulin® and Lantus®, respectively) and nocturnal hypoglycemia (17.25% and 16.31% for Changsulin® and Lantus®, respectively) were similar between the two groups (all P>0.05). Most of the hypoglycemia events were asymptomatic, and no severe hypoglycemia were found in both groups. No differences were observed in rates of AEs (61.77% vs.52.48%) and anti-insulin glargine antibody (after 24 weeks of treatment, 6.91% vs.3.65%) between the two groups (all P>0.05). Conclusions: Changsulin® shows similar efficacy and safety profiles compared with Lantus® and Changsulin® treatment was well tolerated in patients with T2DM.目的： 比较长舒霖®和来得时®治疗2型糖尿病的有效性和安全性。 方法： 多中心、随机、开放、平行组、阳性药物对照、Ⅲ期临床研究，入选578例口服降糖药血糖控制不佳的2型糖尿病患者，按区组分段随机方法将受试者按3∶1的比例随机进入长舒霖®组和来得时®组，治疗24周。比较两组治疗前后糖化血红蛋白（HbA1c）、空腹血糖（FPG）、标准餐后2h血糖（2hPG）、8点指尖血糖谱、结束时HbA1c和FPG达标率以及低血糖事件、不良事件的发生率和甘精胰岛素特异性抗体阳性率。 结果： 治疗24周后长舒霖®组与来得时®组的HbA1c分别下降1.16%和1.25%，FPG分别下降3.05 mmol/L和2.90 mmol/L， 2hPG分别下降2.49 mmol/L和2.38 mmol/L，上述指标两组比较差异无统计学意义（P值均>0.05）。两组治疗前后8点指尖血糖谱以及结束时HbA1c和FPG达标率相似（P值均>0.05）。长舒霖®组与来得时®组总体低血糖发生率 （38.00%和39.01%）和夜间低血糖发生率（17.25%和16.31%）差异均无统计学意义（P值均>0.05），大部分为无症状性低血糖，两组均无重度低血糖。两组不良事件发生率（61.77%比52.48%）和甘精胰岛素特异性抗体阳性率（24周时6.91%比3.65%）差异无统计学意义（P值均>0.05）。 结论： 长舒霖®治疗2型糖尿病的有效性和安全性与来得时®相当，并具有良好的耐受性。.
