PurposeTo evaluate intraperitoneal (IP) nab-paclitaxel in patients with advanced malignancies that are primarily confined to the peritoneal cavity in a phase I trial.MethodsUsing a 3+3 dose escalation of IP nab-paclitaxel on days 1, 8, and 15 of a 28-day cycle, we evaluated six dose levels (35-175mg/m(2)/dose). Maximum tolerated dose (MTD) and pharmacokinetics (PK) of IP nab-paclitaxel were determined.ResultsThere were no dose-limiting toxicities (DLTs) in cohorts 1-3. There was a DLT in one of six patients in cohort 4 (112.5mg/m(2)) (grade 3 neutropenia causing treatment delay>15days) and a DLT in one of three patients in cohort 6 (175mg/m(2)) (grade 4 neutropenia and grade 3 abdominal pain). A second patient in cohort 6 experienced a serious adverse event (cycle 1, grade 4 ANC7days, cycle 4, grade 2 left ventricular dysfunction). This dose level was determined to be above the MTD. No DLTs were seen in seven patients treated in cohort 5 (140mg/m(2)). The MTD of IP nab-paclitaxel was established at 140mg/m(2) on days 1, 8, and 15 of a 28-day cycle. There was a PK advantage for IP nab-paclitaxel, with an IP plasma area under the concentration-time curve (AUC) ratio of 147-fold (range 50-403) and therapeutic range systemic drug levels. Eight of 27 enrolled patients had progression-free survival6months. One patient experienced complete response, and one patient experienced partial response. Six patients had stable disease.ConclusionsWeekly IP nab-paclitaxel has a favorable toxicity profile, a significant pharmacologic advantage, and promising clinical activity.Clinical trial registrationNCT00825201.
