First-line nab-paclitaxel plus carboplatin for patients with advanced non-small cell lung cancer: Results of the NEPTUN study.

Background Platinum-based chemotherapy remains a first-line standard of care for approximately 30% of patients with non-small cell lung cancer (NSCLC) not harboring a druggable alteration. Favorable efficacy and safety of the nab-paclitaxel/carboplatin (nab-P/C) combination was shown in the pivotal phase 3 trial. However, information on effectiveness of nab-P/C in a real-world setting in Germany is missing. The NEPTUN study prospectively investigated the effectiveness and safety of nab-P/C in patients with advanced NSCLC in a real-world setting. Methods Patients with advanced or metastatic NSCLC received first-line nab-P/C according to clinical routine. The primary endpoint was 6-month progression-free survival rate (PFS6). Other endpoints included further effectiveness parameters, safety and quality of life. Data were analyzed descriptively. Results 408 patients were enrolled. PFS6 was 40.8% (95% confidence interval [CI], 35.3-46.2); median PFS was 5.2 months (95% CI, 4.5-5.7). overall response rate was 41.5% (95% CI, 36.3-46.8). Median overall survival (OS) was 10.5 months (95% CI, 9.2-11.6). Subgroup analyses revealed median OS for squamous versus non-squamous histology (11.8 months [95% CI, 9.2-13.8] vs. 9.6 months [95% CI, 7.7-11.2]) and age ≥70 versus Conclusion These real-world data support the effectiveness and safety of nab-P/C as first-line treatment for patients with advanced NSCLC independent of tumor histology. The results are comparable with the pivotal phase 3 trial. No new safety signals emerged.
