Various next-generation ALK TKIs are available as first-line options for ALK-positive NSCLC, with alectinib and lorlatinib being commonly preferred. However, no direct comparison between them has been conducted, making it impossible to pick a winner. We performed an analytic, 'non-comparative' assessment of the two phase 3 pivotal clinical trials showing superiority of alectinib (ALEX) and lorlatinib (CROWN) in comparison to crizotinib. Overall, the two studies were very similar in the study design and patient characteristics, with the exception of the selection and evaluation of brain metastases. PFS hazard ratios numerically favored lorlatinib, both according to the investigator and to BICR. Notably, the 3-year PFS rate was numerically higher with lorlatinib (64%) than with alectinib (46.4%). Despite similar response rates and overall intracranial response, the rate of complete intracranial response was higher with lorlatinib, with a cumulative incidence risk of CNS disease progression at 12 months of 9.4% with alectinib and 2.8% with lorlatinib. The peculiar toxicities of lorlatinib were related to lipidic profile alterations, peripheral oedema and cognitive effects, with no impact on cardiovascular risk nor impairment in quality of life versus crizotinib. Furthermore, the rate of permanent treatment discontinuation due to adverse events was numerically higher with alectinib (26%) than with lorlatinib (7%). In conclusion, despite the immature OS data for both drugs, the efficacy of lorlatinib appears higher than alectinib while maintaining a manageable toxicity profile.
多种下一代ALK酪氨酸激酶抑制剂(TKIs)可作为ALK阳性非小细胞肺癌(NSCLC)的一线治疗选择,其中阿来替尼和洛拉替尼通常更受青睐。然而,尚未对它们进行直接比较,因此无法选出优胜者。我们对两项3期关键临床试验进行了分析性的“非比较性”评估,这两项试验显示阿来替尼(ALEX)和洛拉替尼(CROWN)相较于克唑替尼具有优越性。总体而言,除了脑转移的选择和评估外,两项研究在研究设计和患者特征方面非常相似。根据研究者和独立影像审查(BICR)的评估,无进展生存期(PFS)风险比在数值上更有利于洛拉替尼。值得注意的是,洛拉替尼的3年PFS率在数值上高于阿来替尼(分别为64%和46.4%)。尽管缓解率和总体颅内缓解相似,但洛拉替尼的完全颅内缓解率更高,阿来替尼12个月时中枢神经系统疾病进展的累积发生率风险为9.4%,洛拉替尼为2.8%。洛拉替尼的特殊毒性与脂质谱改变、外周水肿和认知效应有关,与克唑替尼相比,对心血管风险无影响,也未损害生活质量。此外,因不良事件导致永久治疗停药的发生率在数值上阿来替尼(26%)高于洛拉替尼(7%)。总之,尽管两种药物的总生存期(OS)数据尚不成熟,但洛拉替尼的疗效似乎高于阿来替尼,同时保持了可管理的毒性特征。
