PURPOSE 目的

Selpercatinib, a first-in-class, highly selective, and potent CNS-active RET kinase inhibitor, is currently approved for the treatment of patients with RET fusion–positive non–small-cell lung cancer (NSCLC).We provide a registrational data set up date in more than double (n=5316)of the original reported population (n=5144) and better characterization of long-term efficacy and safety. 

Selpercatinib是一种同类最优的创新药,是具有高选择性和强效的中枢神经系统活性RET激酶抑制剂,目前已被批准用于治疗RET融合阳性非小细胞肺癌(NSCLC)患者。我们提供的注册数据的设定日期是原始报告人群(n=5144)的两倍多(n=5316),并更好地描述了长期的有效性和安全性。

METHODS 方法

Patients were enrolled to LIBRETTO-001, a phaseI/II, single-arm, open-label study of selpercatinib in patients with RET-altered cancers. An analysis of patients with RET fusion–positive NSCLC, including 69 treatment-naive and 247 with prior platinum-based chemotherapy, was performed. The primary end point was objective response rate (ORR; RECIST v1.1, independent review committee). Secondary end points included duration of response (DoR), progression-free survival (PFS), overall survival, and safety. 

患者入组LIBRETTO-001,这是一项针对selpercatinib治疗RET改变的癌症患者的I/II期、单臂、开放标签研究。对RET融合阳性NSCLC患者进行了分析,包括69例初治患者和247例既往接受过铂类化疗的患者。主要终点是客观缓解率(ORR;RECIST v1.1,独立审查委员会)。次要终点包括缓解持续时间(DoR)、无进展生存期(PFS)、总生存期和安全性。

RESULTS 结果

Intreatment-naïve patients, the ORR was 84% (95% CI,73 to 92);6% achieved complete responses (CRs). The median DoR was 20.2 months (95% CI, 13.0 to could not be evaluated); 40% of responses were ongoing at the data cutoff (median follow-up of 20.3 months). The median PFS was 22.0 months; 35% of patients were alive and progression-free at the data cutoff (median follow-up of 21.9 months). In platinum based chemotherapy pretreated patients, the ORR was 61% (95% CI, 55 to 67); 7% achieved CRs. The median DoR was 28.6 months (95% CI, 20.4 to could not be evaluated); 49% of responses were ongoing (median follow-up of 21.2 months). The median PFS was 24.9 months; 38% of patients were alive and progression-free (median follow-up of 24.7 months). Of 26 patients with measurable baseline CNS metastasis by the independent review committee, the intracranial ORR was 85% (95% CI, 65 to 96); 27% were CRs. In the full safety population (n=5796), the median treatment duration was 36.1 months. The safety profile of selpercatinib was consistent with previous reports. 

在初治患者中,ORR为84%(95% CI,73-92);6%的人达到了完全缓解(CR)。中位DoR为20.2个月(95% CI, 13.0-无法评估);40%的缓解在数据截止时仍在进行(中位随访时间20.3个月)。中位PFS为22.0个月;35%的患者在数据截止时仍然存活且无进展(中位随访时间21.9个月)。在以铂类为基础的化疗预处理的患者中,ORR为61%(95% CI,55-67);7% 达到CR。中位DoR为28.6个月(95% CI,20.4-无法评估);49%的患者缓解正在进行中(中位随访时间21.2个月)。中位PFS为24.9个月;38%的患者存活且无进展(中位随访时间24.7个月)。在独立审查委员会评估的26例基线可测量的CNS转移患者中,颅内ORR为85%(95% CI,65-96);27%为CR。在完全安全人群中(n=5796),中位治疗持续时间为36.1个月。selpercatinib的安全性与之前的报告一致。

Conclusion 结论

In a large cohort with extended follow-up, selpercatinib continued to demonstrate durable and robust responses, including intracranial activity, in previously treated and treatment-naive patients with RET fusion–positive NSCLC.

在一个长期随访的大型队列研究中,在RET融合阳性NSCLC患者中,selpercatinib继续表现出针对包括颅内活动在内的持久和稳健的缓解。
