      • Abstract

      Background:
      In the treatment of non-small-cell lung cancer (NSCLC), solvent-based paclitaxel (sb-paclitaxel) plus cisplatin can be expected to have high response rate, but strong neurotoxicity is observed. Currently, nanoparticle albumin-bound paclitaxel (nab-paclitaxel) plus carboplatin is considered as one of the standard regimen, and a higher response rate and lower neurotoxicity are expected as compared with sb-paclitaxel plus carboplatin. Therefore, we planned this study to evaluate the efficacy and safety of nab-paclitaxel plus cisplatin in chemotherapy-naïve patients with advanced NSCLC.

      Methods:
      Chemotherapy-naïve patients with advanced NSCLC were eligible. In phase 1 dose escalation cohort (3 + 3 design), patients received nab-paclitaxel (80 or 100 mg/m[2] iv on days 1, 8 and 15) plus cisplatin (60 or 75 mg/m[2] iv on day 1) every 4 weeks. The maximum tolerated dose was not reached. Nab-paclitaxel (100 mg/m[2] iv on days 1, 8 and 15) plus cisplatin (75 mg/m[2] iv on day1) every 4 weeks was selected for phase 2 cohort. The primary endpoint was objective response rate (ORR).

      Results:
      23 patients (phase 1, n = 6; phase 2, n = 17) were enrolled from October 2013 to September 2017, and 22 patients were eligible. The median age was 67.5 years (range 37–75 years), 90.9% were males, 100% had smoked, 45.5% had adenocarcinoma and 81.8% had Stage IV. The ORR was 59.1% (95% confidence interval (CI); 38.7–76.7%) and the disease control rate was 86.4% (95% CI; 66.7–95.3%). The median progression free survival was 5.1 months (95% CI; 4.0–6.7 months) and the median overall survival was 24.2 months (95% CI; 8.4- not estimable (NE) months). The common grade ≥ 3 adverse events was neutropenia (31.8%), leukopenia (27.3%), lung infection (18.2%) and hyponatremia (18.2%). There was one grade 2 interstitial pneumonia and no treatment related death.

      Conclusions:
      Nab-paclitaxel plus cisplatin was well tolerated and associate with encouraging response outcomes in chemotherapy-naïve patients with advanced NSCLC. Further investigation is warranted.
