Efficacy and Safety of Anlotinib in Advanced Non-Small Cell Lung Cancer: A Real-World Study.

Abstract

PurposeThe ALTER0303 trial showed that anlotinib, a novel antiangiogenic tyrosine kinase inhibitor, administered as third-line or further treatment prolonged progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small cell lung cancer (NSCLC). This retrospective study investigated the efficacy and safety of anlotinib in real-world settings.Patients and MethodsMedical records of patients with advanced NSCLC receiving anlotinib as third-line or further treatment were collected, and survival curves were derived using the Kaplan–Meier method. Univariate analysis was performed by log-rank testing. Cox regression analysis was used to evaluate the significance of factors obtained from the univariate analysis.ResultsFifty-two patients with advanced NSCLC were included. The objective response rate was 16%, and the disease control rate was 80%. The median PFS was 4.5 months (95% confidence interval [CI]: 3.6–5.4), and the median OS was 9 months (95% CI: 6.5–11.5). Univariate analysis revealed that the group of patients with longer PFS and OS included Eastern Cooperative Oncology Group performance status (ECOG PS) ≤1, ≤2 distant metastases, no liver metastases, ≤3 previous treatment lines, and ≤2 previous chemotherapy lines. Cox regression analysis demonstrated that only patients with ECOG PS ≤1 or no liver metastases had longer PFS and OS. Grade 3 treatment-related adverse events were reported in 14% of the patients, but no life-threatening adverse events were reported.ConclusionAnlotinib was well tolerated and effective in patients with advanced NSCLC in real-world conditions. Patients with ECOG PS ≤1 or no liver metastases have longer PFS and OS.
