阿美替尼有望成为EGFR突变的NSCLC患者的一线治疗选择

Aumolertinib(阿美替尼,原名Almonertinib;HS-10296)是一种新型三代表皮生长因子受体(EGFR)酪氨酸激酶抑制剂(TKI),可选择性、不可逆的抑制EGFR致敏性和T790M突变,在我国已获批上市。

近期发表在Journal of Clinical Oncology杂志上的AENEAS研究是一项双盲的3期临床试验,旨在比较阿美替尼与吉非替尼作为局部晚期或转移性EGFR突变的非小细胞肺癌NSCLC)的一线治疗的疗效和安全性。

从我国的53个研究中心招募了组织学或细胞学明确诊断的局部晚期或转移性、携带EGFR突变(敏感性突变,如19外显子缺失和L858突变)的NSCLC患者,1:1随机分成两组,每日接受阿美替尼(110mg)或吉非替尼(250mg)治疗。主要终点是无进展生存期。


两组的无进展生存率

共招募了429位初治的局部晚期或转移性NSCLC患者。阿美替尼组的中位无进展生存期显著长于吉非替尼组(19.3个月 vs 9.9个月;风险比[HR] 0.46,95% CI 0.36-0.60, p<0.0001)。两组的客观缓解率和疾病控制率无明显差异(客观缓解率:73.8% vs 72.1%;疾病控制率:93.0% vs 96.7%)。阿美替尼组和吉非替尼组的中位缓解持续时间分别是18.1个月和8.3个月。


无进展生存率的亚组分析

阿美替尼组和吉非替尼组≥3级的不良事件的发生率分别是36.4%和35.8%。阿美替尼组所有级别的红疹和腹泻的发生率分别是23.4%和16.4%,在吉非替尼组这两种不良事件的发生率分别是41.4%和35.8%。

综上,阿美替尼是一种耐受性良好的三代表皮生长因子受体酪氨酸激酶抑制剂,有望成为EGFR突变的NSCLC患者的一线治疗选择。
