化疗诱导的造血干细胞和祖细胞(HSPC)损伤导致多系骨髓抑制。Trilaciclib是一种正在开发的静脉注射CDK4/6抑制剂,可在化疗期间主动保护HSPC和免疫系统功能(骨髓抑制)。临床前,trilaciclib可短暂维持HSPC处于G1停滞状态,保护其免受化疗损伤,从而加快造血恢复,增强抗肿瘤免疫力。

 

这是一项Ib期(开放标签、剂量测定)和II期(随机、双盲安慰剂对照)研究,研究曲拉西布联合依托泊苷/卡铂(E/P)治疗未成熟的广泛期小细胞肺癌患者的安全性、有效性和PK。患者在每个周期的第1-3天,在E/P之前接受曲拉西利布或安慰剂。预先选择了终点以评估曲拉西布对骨髓抑制和抗肿瘤疗效的影响。该研究结果已在线发表于Ann Oncol。

结果显示,共有122名患者入组,其中第1部分的19名患者和第2部分的75名患者接受研究药物。曲拉西布在中性粒细胞、RBC(红细胞)和淋巴细胞指标方面均有改善。与安慰剂(83.8%)相比,trilaciclib(50%)的≥G3不良事件(AEs)较少,从而改善了曲拉西利布+E/P的安全性,主要是由于血液学毒性较少。没有发生曲拉西利布相关的≥G3 AEs。曲拉西利布与安慰剂的抗肿瘤疗效评估分别显示:ORR(66.7% vs. 56.8%,P = 0.3831);中位PFS[6.2 vs. 5.0米;HR 0.71;P = 0.1695];OS(10.9 vs. 10.6m;HR 0.87;P = 0.6107)。

综上所述,该研究结果表明,曲拉西利布表现出了对患者化疗耐受性的改善,如骨髓保存在多个造血系中,导致更少的支持性护理干预和剂量减少,改善了安全性,且不损害抗肿瘤疗效。这些数据证明了曲拉西利布的骨髓保存优势。
