Gene Therapy00:59

Gene Therapy

27.3K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

科学领域:

  • 血管医学 血管医学
  • 再生医学是一种再生医学.
  • 临床试验 临床试验

背景情况:

  • 慢性四肢威胁性缺血症 (CLTI) 缺乏FDA批准的治疗方法来治疗伤口愈合,这表明存在重大未满足的医疗需求.
  • 现有的CLTI生物研究往往集中在终期患者,其主要结果是没有截肢的生存.
  • 这项试验研究了AMG0001,一种编码肝细胞生长因子 (HGF) 的等离子体,用于促进CLTI患者的愈.

研究的目的:

  • 评估肌肉内AMG0001在促进CLTI和神经缺血性患者的愈的疗效.
  • 与安慰剂相比,评估AMG0001的安全性和有效性.
  • 为了确定AMG0001管理的最佳剂量和时间.

主要方法:

  • LEGenD-1试验是一项双盲,随机,安慰剂控制的II期研究,在美国22个地点进行.
  • 75名患有神经性和特定输液标准的参与者被随机分配给AMG0001 (4毫克或8毫克) 或安慰剂.
  • 肌肉内注射是在0,28,56和84日沿着引导动脉路径进行的.

主要成果:

  • 完全愈合的中位时间在AMG0001与安慰剂相比显著缩短 (84对280天;P=0.007).
  • 在6个月内,63.3%的AMG0001治疗参与者实现了愈合,而安慰剂治疗38.5% (P=0.053).
  • 在12个月内,AMG0001的治愈率为77.6%,而安慰剂为46.2% (P=0.010),各组的不良事件相似.

结论:

  • 在中度CLTI和神经缺血性的患者中,对AMG0001的解剖学向肌肉输送显著加快了愈合.
  • AMG0001代表了一个有前途的非手术治疗策略,用于CLTI相关的伤口愈合.
  • 对AMG0001的进一步调查可能会为患有CLTI的患者带来新的治疗选择.
