评价了ISIS 2922和ISIS 4015(与人巨细胞病毒(CMV)和单纯疱疹病毒(HSV)RNA互补的硫代磷酸寡核苷酸)的视网膜毒性。在兔视网膜中未引起永久性毒性变化的ISIS 2922的玻璃体内浓度为10 µ M,在猪视网膜中为5 µM。3 µ M浓度与一过性炎症反应相关,1 µ M浓度不会引起视网膜毒性或炎症。ISIS 4015在10 μ M的剂量下显示出非常轻微的毒性,没有永久性视网膜变化和非常轻微的炎症;当在病毒接种前1天和1周注射时,该剂量有效改善或预防HSV-1视网膜炎。这些寡核苷酸具有低的眼内治疗指数。指出了改善这些化合物的治疗指数的尝试。只有临床试验可以确定ISIS 2922治疗CMV视网膜炎的毒性特征。
Retinal toxicity of ISIS 2922 and ISIS 4015, phosphorothioate oligonucleotides complementary to human cytomegalovirus (CMV) and herpes simplex virus (HSV) RNA, were evaluated. The intravitreal concentration of ISIS 2922 found not to cause permanent toxic changes in the rabbit retina was 10 µMand in the pig retina, 5 µM. The 3 µMconcentration was associated with a transient inflammatory response, and 1 µMcaused no retinal toxicity or inflammation. ISIS 4015 showed very mild toxicity with no permanent retinal changes and very mild inflammation at doses of 10 µ{ilM}; this dose was effective in ameliorating or preventing HSV-1 retinitis when injected 1 day and 1 week prior to virus inoculation. These oligonucleotides have a low intraocular therapeutic index. Attempts to improve the therapeutic index of these compounds are indicated. Only a clinical trial can determine the toxicity profile of ISIS 2922 for the treatment of CMV retinitis.
