Abstract

Real-world data on the first-line treatment of patients with advanced non-small cell lung cancer (NSCLC) are still limited. The NEPTUN study evaluated effectiveness and safety of first-line nab-paclitaxel (Abraxane) plus carboplatin (nab-P/C) in patients with advanced NSCLC in routine clinical practice in Germany. Patients included in our study were aged ≥18 years, diagnosed with locally advanced or metastatic NSCLC and with decision for first-line nab-P/C in routine clinical practice. Primary objective was 6-month progression-free survival rate (PFS6), secondary objectives included overall survival (OS), overall response rate (ORR) and safety. From 2016 to 2019, 408 patients from 75 sites were enrolled. PFS6 was 39.5% (95% CI: 34.2-44.8), median PFS was 5.1 months (95% CI: 4.6-5.6), ORR was 42.9% (95% CI: 37.7-48.2). Median OS was 10.5 months (95% CI: 9.2-11.6). In subgroup analyses, median OS for squamous vs non-squamous histology was 11.5 months (95% CI: 9.2-13.8) vs 9.8 months (95% CI: 8.1-11.3) and for patients aged ≥70 vs <70 years median OS was 12.4 months (95% CI: 9.8-15.1) vs 9.6 months (95% CI: 7.7-11.1). Adverse events (AEs) related to nab-paclitaxel were reported in 247 (66.4%) patients, while carboplatin-related AEs were documented in 224 (60.2%) patients. Most frequently related AEs were leukopenia (22.3%) for nab-paclitaxel and anemia (20.2%) for carboplatin. Nab-P/C-related deaths were reported in 2 (0.5%) patients (sepsis and neutropenic sepsis). No new or unexpected safety signals emerged. These results support the effectiveness and safety of first-line nab-P/C in patients with advanced NSCLC reported in the pivotal trial and highlight the clinical value of this regimen in the real-world setting.
