FDA批准Cosela(trilaciclib)用于减少化学疗法引起的骨髓抑制

2021-02-14 Allan MedSci原创

Cosela(trilaciclib)可通过抑制细胞周期蛋白依赖性激酶4/6(CDK 4/6)来帮助保护骨髓细胞免受化学疗法的损害。

近日,美国食品药品监督管理局(FDA)批准Cosela(trilaciclib)用于减少小细胞肺癌患者经化学疗法引起的骨髓抑制率。Cosela(trilaciclib)可通过抑制细胞周期蛋白依赖性激酶4/6(CDK 4/6)来帮助保护骨髓细胞免受化学疗法的损害。

化学疗法药物旨在杀死癌细胞,但也会损害正常组织。骨髓特别容易受到化学疗法的损害。骨髓产生红血球、白血球和血小板。骨髓受损时,骨髓产生的这些细胞较少,从而导致疲劳、感染风险增加和出血以及其他问题。Cosela(trilaciclib)可能有助于保护正常的骨髓细胞免受化学疗法的有害影响。

FDA药物评估和研究中心Albert Deisseroth博士说:“对于广泛期小细胞肺癌患者,保护骨髓功能可能使化疗更加安全,并使他们能够按计划按时完成治疗”。

III期随机、双盲、安慰剂对照研究评估了Cosela(trilaciclib)对广泛期小细胞肺癌患者的疗效。245例患者接受化疗前静脉注射Cosela或安慰剂。结果显示,接受Cosela治疗的患者发生严重中性粒细胞减少症的几率低于接受安慰剂的患者。在患有严重中性粒细胞减少症的患者中,平均而言,接受Cosela治疗的患者比接受安慰剂的患者有更短的持续时间。

通过对人类和小鼠前列腺癌细胞进行研究,来自约翰霍普金斯大学的癌症成像专家开发出了一种新型的方法来用于发现和消灭恶性的肿瘤细胞。这种方法名为治疗诊断学成像,其可以直接打靶和追踪潜在的药物疗法来专门消灭癌细胞。这种新方法依赖于结合在化疗药物的钝化形式上,来最终吸附于肿瘤细胞表面的特殊蛋白上,最终检测药物对肿瘤的作用,这种高度的药物-蛋白复合物(或者nanoplex)的结合允许其进入癌细胞的内部来发挥杀
