克拉屈滨目前在38个国家以Mavenclad的名义获得批准,包括欧盟,加拿大和澳大利亚。克拉屈滨可适用于经干扰素治疗失败后活动性的伴有临床意义的贫血、中性粒细胞减少、血小板减少以及疾病相关症状的毛细胞白血病(HCL)的治疗。克拉屈滨的抑瘤活性与脱氧胞苷激酶和脱氧核苷酸激酶活性有关。它主要以被动转运进入细胞,在细胞内被脱氧胞苷激酶磷酸化,转化为克拉屈滨三磷酸,掺合到DNA分子中,妨碍DNA断裂后的修复作用,造成NADATP的耗竭,破坏细胞代谢,影响细胞的DNA合成。因此克拉屈滨对分化或静止期的淋巴细胞和单核细胞均有抑制DNA合成和修复的作用。

MULT SCLER:克拉屈滨可以改善复发性多发性硬化症患者生活质量

克拉屈滨是一种脱氧腺苷类似物。在一个名为“克拉屈滨口服治疗多发性硬化(CLARITY)”的III期临床试验中,克拉屈滨能够显著抑制病变的积累,复发,以及3个月持续残疾进展。由于克拉屈滨可能增加癌症的风险,以及临床数据不足,监管机构在2011年拒绝批准口服克拉屈滨。但是现在,欧洲药品管理局对于口服克拉屈滨在2017年第三季度得到许可证持积极态度。
