LY2963016 (LY IGlar) and Lantus (IGlar) are insulin glargine products with identical amino acid sequences. This was a phase 1 single-site, randomized, subject- and investigator-blinded, 4-treatment, 4-period crossover study to compare the pharmacokinetic (PK) and pharmacodynamic (PD) properties of LY IGlar and IGlar at 2 different doses. Fasted healthy subjects were randomly assigned to receive 2 single doses of LY IGlar and IGlar (0.3 and 0.6 U/kg for each product). Blood samples were collected up to 24 hours postdose to assess PK, and a euglycemic clamp lasting up to 24 hours postdose was conducted to assess PD. Twenty-four healthy subjects aged 23 to 52 years participated in the study. The primary PK parameters (area under the concentration versus time curve from 0 to 24 hours [AUC ] and maximum observed drug concentration [C ]) and PD parameters (total amount of glucose infused during the clamp [G ] and maximum glucose infusion rate [R ]) were not statistically different between LY IGlar and IGlar at either dose. No safety concerns were noted with either drug. The study demonstrated that the PK and PD parameters for LY IGlar and IGlar were comparable following single doses at both 0.3 and 0.6 U/kg.
LY2963016(LY 精氨酸胰岛素)和 Lantus(IGlar)是氨基酸序列完全相同的胰岛素精氨酸产品。这是一项在单个研究地点进行的、随机的、受试和研究者双盲的、4 种治疗方案、4 个周期的交叉研究,旨在比较 LY 精氨酸胰岛素和 IGlar 在两种不同剂量下的药代动力学(PK)和药效动力学(PD)特性。禁食健康受试者被随机分配接受 2 次单剂量 LY 精氨酸胰岛素和 IGlar(每种产品 0.3 和 0.6 U/kg)。给药后采集血样,直至 24 小时,以评估 PK;给药后进行持续 24 小时的正葡萄糖钳夹试验,以评估 PD。24 名年龄在 23 至 52 岁的健康受试者参加了这项研究。主要 PK 参数(0 至 24 小时时间曲线下的浓度面积 [AUC ]和最大药物浓度 [C ])和 PD 参数(钳夹期间输注的总葡萄糖量 [G ]和最大葡萄糖输注率 [R ])在两种剂量下 LY 精氨酸胰岛素和 IGlar 之间均无统计学差异。两种药物均未观察到安全性问题。研究表明,LY 精氨酸胰岛素和 IGlar 在 0.3 和 0.6 U/kg 两种剂量下单次给药后,其 PK 和 PD 参数具有可比性。
