Patients with type 2 diabetes require treatment intensification to maintain glycemic control. Clinician reluctance, patient injection fears, hypoglycemia, weight gain, or other objections may lead to clinical inertia, whereby therapy is not intensified and patients live with uncontrolled hyperglycemia and increased risk for complications. Initiation of injectable therapy with a glucagon-like peptide (GLP)-1 receptor agonist and/or basal insulin is a recommended option for patients with type 2 diabetes inadequately controlled on one or more oral agents.
This article reviews clinical evidence and provides information on dosing and administration of iGlarLixi, a titratable fixed-ratio combination of insulin glargine and the GLP-1 receptor agonist lixisenatide that effectively lowers both fasting and postprandial glucose levels.
In phase 3 trials, iGlarLixi provided greater A1C reduction than insulin glargine or lixisenatide alone, without increased hypoglycemia risk compared with insulin glargine. iGlarLixi did not lead to weight gain versus insulin glargine and was associated with a lower frequency of gastrointestinal adverse effects than lixisenatide. iGlarLixi was recently approved by the U.S. Food and Drug Administration to improve glycemic control in adults with type 2 diabetes inadequately controlled on basal insulin (<60 units daily) or lixisenatide. iGlarLixi is administered by subcutaneous injection once daily, and the dose is titrated based on each patient's insulin needs using a simple titration algorithm.
iGlarLixi offers an effective and well-tolerated treatment option for patients with type 2 diabetes requiring additional glycemic control, with comparable or improved safety outcomes than its separate components. Because of its simple regimen and low rate of adverse effects, iGlarLixi may improve adherence and, consequently, therapeutic outcomes.
2型糖尿病患者需要强化治疗以维持血糖控制。临床医生的顾虑、患者对注射的恐惧、低血糖、体重增加或其他问题可能导致临床惰性,即治疗未得到强化,患者处于高血糖未控制状态,并发症风险增加。对于使用一种或多种口服药物血糖控制不佳的2型糖尿病患者,起始使用胰高血糖素样肽(GLP)-1受体激动剂和/或基础胰岛素进行注射治疗是一种推荐选择。
本文回顾临床证据,并提供关于iGlarLixi(甘精胰岛素和GLP-1受体激动剂利司那肽的可滴定固定比例复方制剂,可有效降低空腹和餐后血糖水平)给药剂量及用法的信息。
在3期试验中,iGlarLixi降低糖化血红蛋白(A1C)的效果优于单独使用甘精胰岛素或利司那肽,与甘精胰岛素相比低血糖风险未增加。与甘精胰岛素相比,iGlarLixi不会导致体重增加,且胃肠道不良反应的发生频率低于利司那肽。iGlarLixi最近获得美国食品药品监督管理局批准,用于改善接受基础胰岛素(每日<60单位)或利司那肽治疗血糖控制不佳的2型糖尿病成人患者的血糖水平。iGlarLixi通过皮下注射每日给药1次,剂量根据每位患者的胰岛素需求使用简单的滴定算法进行滴定。
对于需要进一步控制血糖的2型糖尿病患者,iGlarLixi提供了一种有效且耐受性良好的治疗选择,其安全性结果与其单独成分相当或更优。由于其给药方案简单且不良反应发生率低,iGlarLixi可能会提高依从性,从而改善治疗效果。
