肿瘤治疗检测基因临床应用结果
靶向药物研究立项的依据:先前的临床试验已经证明了聚(ADP-核糖)聚合酶(PARP)抑制剂(PARPis)对涉及同源重组修复(HRR)基因突变的癌症患者的潜在疗效。此外,随着肿瘤突变负担的增加,HRR 基因突变的癌症可以通过免疫检查点抑制剂 (ICI) 得到有效治疗。我们提议开展一项多中心、单组 II 期试验(IMAGENE 试验),以评估尼拉帕尼 (PARPi) 与程序性细胞死亡 1 抑制剂联合治疗对 HRR 基因突变癌症患者的疗效和安全性,这些患者难治性使用基于下一代测序的循环肿瘤 DNA (ctDNA) 和肿瘤组织分析的 ICIs 疗法。先前 ICI 治疗后进展;和 Eastern Cooperative Oncology Group Performance Status ≤ 1。主要终点是所有患者的确认客观反应率 (ORR)。次要终点包括使用 Caris Assure(CARIS,美国)确认的 ctDNA 的 HRR 基因突变患者的 ORR。 IMAGENE 试验的目标样本量为 57 名患者。将使用 Caris Assure、蛋白质组分析和 T 细胞库分析同时进行生物标志物分析,以揭示外周血中的肿瘤免疫监视。预期靶向药物研究的客观数据:我们的试验旨在证实 PARPi 加 ICI 联合治疗对 ICI 耐药患者的临床益处.此外,通过转化研究,我们的试验将阐明哪些患者即使在 ICIs 失败后仍可从 HRR 基因突变肿瘤患者的靶向联合治疗中获益。试验注册:IMAGENE 试验:jRCT,临床试验编号: jRCT2051210120,注册日期:2021年11月9日。关键词:同源重组修复;免疫检查点抑制剂;尼拉帕尼; PARP抑制剂;肿瘤不可知疗法。
肿瘤发生与革命国际数据库描述:
Background: Previous clinical trials have demonstrated the potential efficacy of poly (ADP-ribose) polymerase (PARP) inhibitors (PARPis) in patients with cancer involving homologous recombination repair (HRR) gene-mutation. Moreover, HRR gene-mutated cancers are effectively treated with immune checkpoint inhibitors (ICIs) with the increase in tumor mutation burden. We have proposed to conduct a multicenter, single-arm phase II trial (IMAGENE trial) for evaluating the efficacy and safety of niraparib (PARPi) plus programmed cell death-1 inhibitor combination therapy in patients with HRR gene-mutated cancers who are refractory to ICIs therapy using a next generation sequencing-based circulating tumor DNA (ctDNA) and tumor tissue analysis.Methods: Key eligibility criteria for this trial includes HRR gene-mutated tumor determined by any cancer gene tests; progression after previous ICI treatment; and Eastern Cooperative Oncology Group Performance Status ≤ 1. The primary endpoint is the confirmed objective response rate (ORR) in all patients. The secondary endpoints include the confirmed ORR in patients with HRR gene-mutation of ctDNA using the Caris Assure (CARIS, USA). The target sample size of the IMAGENE trial is 57 patients. Biomarker analyses will be performed in parallel using the Caris Assure, proteome analysis, and T cell repertoire analysis to reveal tumor immunosurveillance in peripheral blood.Expected outcome: Our trial aims to confirm the clinical benefit of PARPi plus ICI combination therapy in ICI-resistant patients. Furthermore, through translational research, our trial will shed light on which patients would benefit from the targeted combination therapy for patients with HRR gene-mutated tumor even after the failure of ICIs.Trial registration: The IMAGENE trial: jRCT, Clinical trial no.: jRCT2051210120, Registered date: November 9, 2021.Keywords: Homologous recombination repair; Immune checkpoint inhibitor; Niraparib; PARP inhibitor; Tumor-agnostic therapy.
