A Study of Gemcitabine, Nab-paclitaxel, Capecitabine, Cisplatin, and Irinotecan in Metastatic Pancreatic Cancer

This was a two-part, single-institution, open-label, dose-escalation, phase 1/2 study to evaluate the clinical activity of gemcitabine, nab-paclitaxel, capecitabine, cisplatin, and irinotecan in patients with metastatic pancreatic cancer. Part 1 of the study was a Phase 1 3 + 3 dose escalation study designed to evaluate the maximally tolerated dose (MTD) and safety of increasing doses of nab-paclitaxel in combination with gemcitabine, capecitabine, cisplatin, and irinotecan. There were two cohorts of dose escalations. The two cohorts differed based on the treatment cycle length (28 days for Cohort 1 and 21 days for Cohort 2). Dose escalation started with Cohort 1. Enrollment for Cohort 2 dose level 1 began once dose level 2 of Cohort 1 was shown to be safe and did not exceed MTD. Part 2 was a Phase 2 expansion cohort study for the evaluation of efficacy once the MTD had been determined.
