To compare the efficacy and safety between pyrotinib (Pyr) and trastuzumab emtansine (T-DM1) in pre-treated human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC) patients.
A comprehensive literature search of the PubMed, EMBASE, and Web of Science was performed in August 2020. Randomized clinical trials comparing the efficacy and safety between different anti-HER2 regimens in patients pre-treated with trastuzumab (Tra) and a taxane in metastatic settings (≤second-line treatment) were included. A fixed effects network meta-analysis based on the Bayesian inferential framework was conducted for progression-free survival (PFS), overall survival (OS), overall response rate (ORR), and grade ≥3 adverse events (AEs). Values of surface under cumulative ranking probability curve (SUCRA) were calculated to offer a ranking of all regimens.
Twelve studies with 4,353 subjects were identified. Nine regimens were included into the network: T-DM1, lapatinib-capecitabine (Lap-Cap), Tra-Cap, Cap, neratinib (Ner), pertuzumab (Per)-Tra-Cap, Pyr-Cap, atezolizumab (Ate)-T-DM1, and Ner-Cap. For PFS, Pyr-Cap was more favorable than T-DM1 (hazard ratio, 95% confidence interval: 0.77, 0.70-0.86), Lap-Cap (0.64, 0.59-0.69), Tra-Cap (0.63, 0.56-0.70), Cap (0.50, 0.45-0.56), Ner (0.59, 0.51-0.69), Per-Tra-Cap (0.68, 0.59-0.79), and Ner-Cap (0.72, 0.64-0.81). For OS, Pyr-Cap showed further improvement than Lap-Cap (hazard ratio, 95% confidence interval: 0.71, 0.52-0.99), Cap (0.68, 0.49-0.96), and Ner (0.65, 0.45-0.94). For ORR, Pyr-Cap was significantly superior than Cap (odds ratio, 95% confidence interval: 7.87, 1.22-56.51). No significant difference was observed in grade ≥3 AEs among all the regimens. Pyr-Cap ranked in the highest in PFS, OS, ORR, and grade ≥3 AEs (SUCRA = 99.4, 89.7, 86.4, and 89.3%).
These results indicate that Pyr may be more effective than T-DM1 in HER2+ MBC patients pre-treated with Tra and a taxane. However, it may be associated with more grade ≥3 AEs.
比较吡咯替尼(Pyr)与曲妥珠单抗-美坦新(T-DM1)在经治的人表皮生长因子受体2阳性(HER2+)转移性乳腺癌(MBC)患者中的疗效和安全性。
2020年8月对PubMed、EMBASE和Web of Science进行了全面的文献检索。纳入了在转移性环境(≤二线治疗)中接受曲妥珠单抗(Tra)和紫杉烷预处理的患者中比较不同抗HER2方案疗效和安全性的随机临床试验。基于贝叶斯推理框架进行固定效应网络荟萃分析,以评估无进展生存期(PFS)、总生存期(OS)、总缓解率(ORR)和≥3级不良事件(AE)。计算累积排序概率曲线下面积(SUCRA)值以对所有方案进行排序。
共纳入12项研究,4353名受试者。9种方案纳入网络:T-DM1、拉帕替尼-卡培他滨(Lap-Cap)、Tra-卡培他滨(Tra-Cap)、卡培他滨(Cap)、来那替尼(Ner)、帕妥珠单抗(Per)-Tra-卡培他滨、Pyr-卡培他滨、阿特珠单抗(Ate)-T-DM1和Ner-卡培他滨。对于PFS,Pyr-卡培他滨比T-DM1更具优势(风险比,95%置信区间:0.77,0.70-0.86)、Lap-Cap(0.64,0.59-0.69)、Tra-Cap(0.63,0.56-0.70)、Cap(0.50,0.45-0.56)、Ner(0.59,0.51-0.69)、Per-Tra-Cap(0.68,0.59-0.79)和Ner-卡培他滨(0.72,0.64-0.81)。对于OS,Pyr-卡培他滨比Lap-Cap(风险比,95%置信区间:0.71,0.52-0.99)、Cap(0.68,0.49-0.96)和Ner(0.65,0.45-0.94)有进一步改善。对于ORR,Pyr-卡培他滨显著优于Cap(优势比,95%置信区间:7.87,1.22-56.51)。所有方案中≥3级AE未观察到显著差异。Pyr-卡培他滨在PFS、OS、ORR和≥3级AE方面排名最高(SUCRA = 99.4%、89.7%、86.4%和89.3%)。
这些结果表明,在接受Tra和紫杉烷预处理的HER2+ MBC患者中,Pyr可能比T-DM1更有效。然而,它可能与更多的≥3级AE相关。
