This Phase 2 study evaluated the efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) in advanced non-small cell lung cancer (NSCLC) patients after programmed cell death 1 or programmed death ligand 1 (PD-(L)1) inhibitor failure. Twenty-nine patients received nab-paclitaxel (100 mg/m²). The objective response rate (ORR) was 55.2% (95% CI: 28.1%-79.6%), and the disease control rate (DCR) was 86.2% (95% CI: 65.9%-97.0%). Median progression-free survival (PFS) was 5.6 months (95% CI: 4.4-6.7 months), and median overall survival (OS) was 11.9 months (95% CI: 0.8-23.0 months). Grade 3 or higher toxicities were observed, primarily hematologic. Good performance status and response to prior PD-(L)1 inhibitor therapy predicted longer PFS.
