Purpose: Assess safety and efficacy of nivolumab plus nab-paclitaxel and gemcitabine in patients with locally advanced/metastatic pancreatic cancer in a two-part, open-label, phase I trial. Patients and Methods: Fifty chemotherapy-naive patients received nab-paclitaxel 125 mg/m2 plus gemcitabine 1,000 mg/m2 (days 1, 8, and 15) and nivolumab 3 mg/kg (days 1 and 15) in 28-day cycles. The primary endpoints were dose-limiting toxicities (DLTs; part 1) and grade 3/4 treatment-emergent adverse events (TEAEs) or treatment discontinuation due to TEAEs (parts 1/2). Secondary efficacy endpoints were progression-free survival (PFS), overall survival (OS), and response. Assessment of programmed cell death-ligand 1 (PD-L1) expression was an exploratory endpoint; additional biomarkers were assessed post hoc. Results: One DLT (hepatitis) was reported in part 1 among six DLT-evaluable patients; 48 of 50 patients experienced grade 3/4 TEAEs and 18 discontinued treatment due to TEAEs. One grade 5 TEAE (respiratory failure) was reported. Median [95% confidence interval (CI)] PFS/OS was 5.5 (3.25–7.20 months)/9.9 (6.74–12.16 months) months, respectively [median follow-up for OS, 13.6 months (95% CI, 12.06–23.49 months)]. Overall response rate (95% CI) was 18% (8.6%–31.4%). Median PFS/OS was 5.5/9.7 months (PD-L1 <5%) and 6.8/11.6 months (PD-L1 ≥5%), respectively. Proportion of peripheral Ki67þ CD8þ/CD4þ cells increased significantly from baseline to cycle 3; median peak on-treatment Ki67þ CD8þ T-cell values were higher in responders than in nonresponders. Conclusions: The safety profile of nivolumab plus nab-paclitaxel and gemcitabine at standard doses in advanced pancreatic cancer was manageable, with no unexpected safety signals. Overall, the clinical results of this study do not support further investigation.
