用 CSL346 阻断血管内皮生长因子 (VEGF)-B 治疗糖尿病肾病:2A 期随机对照试验。
背景:糖尿病肾病(DKD)患者血管内皮生长因子 B(VEGF-B)表达的增加与肾小球荚膜细胞中脂质沉积的增加有关。使用抗血管内皮生长因子 B 抗体降低糖尿病肾病动物模型中血管内皮生长因子 B 的活性可改善肾小球损伤的组织学证据并降低白蛋白尿;其效果归因于防止肾脏中异位脂质沉积。CSL346 是一种新型人源化单克隆抗体,能与血管内皮生长因子-B 高亲和力结合。针对 2 型糖尿病患者的血管内皮生长因子-B 可改善 DKD 进展指标:一项国际随机、双盲、安慰剂对照 2a 期研究(NCT04419467)评估了 CSL346(8 mg/kg 或 16 mg/kg,每 4 周皮下注射一次,共 12 周)对尿白蛋白与肌酐比值 (UACR) ≥150 mg/g (17.0 mg/mmol)、eGFR >20 mL/min/1.73m2 的 2 型糖尿病患者的疗效。对 CSL346 的疗效、安全性/耐受性、药代动力学和药效学进行了评估。主要分析比较了两个 CSL346 剂量组与安慰剂组在第 16 周时 UACR 对数变换后与基线相比的变化:结果:共有 114 人接受了随机治疗。与安慰剂相比,第 16 周时 CSL346 并未明显降低 UACR(CSL346 组合组与安慰剂的差异 95% 置信区间]:4.0% [-14.7, 26.8]).此外,在参试者亚组(肾功能损害程度或使用钠-葡萄糖共转运体 2 [SGLT2] 抑制剂)或反映近端肾小管损伤的尿液生物标志物方面均未见效果。CSL346 的耐受性总体良好;但从第 2 周开始,CSL346 16 mg/kg 与安慰剂相比,舒张压显著升高,差异范围为 +3.8 至 +5.3 mmHg(第 16 周时,P = 0.002):结论:与安慰剂相比,CSL346 在 16 周时并不能降低 2 型糖尿病和 DKD 参与者的 UACR,而且与舒张压升高有关。

期刊介绍: The Journal of the American Society of Nephrology (JASN) stands as the preeminent kidney journal globally, offering an exceptional synthesis of cutting-edge basic research, clinical epidemiology, meta-analysis, and relevant editorial content. Representing a comprehensive resource, JASN encompasses clinical research, editorials distilling key findings, perspectives, and timely reviews. Editorials are skillfully crafted to elucidate the essential insights of the parent article, while JASN actively encourages the submission of Letters to the Editor discussing recently published articles. The reviews featured in JASN are consistently erudite and comprehensive, providing thorough coverage of respective fields. Since its inception in July 1990, JASN has been a monthly publication. JASN publishes original research reports and editorial content across a spectrum of basic and clinical science relevant to the broad discipline of nephrology. Topics covered include renal cell biology, developmental biology of the kidney, genetics of kidney disease, cell and transport physiology, hemodynamics and vascular regulation, mechanisms of blood pressure regulation, renal immunology, kidney pathology, pathophysiology of kidney diseases, nephrolithiasis, clinical nephrology (including dialysis and transplantation), and hypertension. Furthermore, articles addressing healthcare policy and care delivery issues relevant to nephrology are warmly welcomed.
