摘要

NNC0195-0092是一种可逆的白蛋白结合GH衍生物,开发为每周一次给药。目的:本研究的目的是评估NNC0195-0092的安全性、局部耐受性、药效学和药代动力学,与每日GH比较。设计和设置:这是一项1期随机、开放标签、主动对照、多剂量、剂量递增试验。患者:34名生长激素缺乏的成人受试者(男性,n = 25)接受了生长激素治疗。干预措施和主要结果指标:受试者被依次分配到四个队列,每组8名受试者,在每个队列中随机(3:1)每周一次NNC0195-0092 (n = 6),持续4周(0.02、0.04、0.08和0.12 mg/kg)或每天注射Norditropin NordiFlex (n = 2),持续4周,剂量与生长激素的试验前剂量相同。在开始下一个剂量水平的NNC0195-0092治疗之前进行了安全性评估。试验开始前14天停止每日GH治疗。抽取血液样本进行安全性评估、药代动力学、药效学(IGF-1和igf结合蛋白-3)和免疫原性研究。结果:0.02、0.04和0.08 mg/kg NNC0195-0092与每日注射Norditropin NordiFlex剂量水平的不良事件数量相似,而NNC0195-0092最高剂量水平(0.12 mg/kg)的不良事件数量更多。NNC0195-0092(曲线下面积[0-168h])和峰值血药浓度呈剂量依赖性增加,IGF-1水平呈剂量依赖性增加。 IGF-1 profiles were elevated for at least 1 week, and for the 0.02-mg/kg and 0.04-mg/kg NNC0195-0092 doses, the observed IGF-1 levels were similar to the levels for the active control group. CONCLUSION: Four once-weekly doses of NNC0195-0092 (dose range 0.02-0.12 mg/kg) administered to adult patients with GH deficiency were well tolerated, and IGF-1 profiles were consistent with a once-weekly treatment profile. No clinically significant safety and tolerability signals causally related to NNC0195-0092 were identified, nor were any immunogenicity concerns revealed.
