Abstract

Background In a phase III trial in patients with metastatic pancreatic cancer (MPC), nab-paclitaxel plus gemcitabine (nab-P/Gem) demonstrated greater efficacy but higher rates of peripheral neuropathy (PN) versus Gem. This exploratory analysis aimed to characterise the frequency, duration, and severity of PN with nab-P/Gem in the MPACT study. Patients and methods Patients with previously untreated MPC received nab-P/Gem or Gem. PN was evaluated using a broad-spectrum group of Standardised Medical Dictionary for Regulatory Activities Queries (SMQ) and graded by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.0. A case report form was completed by physicians on day 1 of each cycle (also graded by NCI CTCAE version 3.0). Results In the nab-P/Gem arm, 227/421 patients (54%) experienced any-grade PN and 70 (17%) experienced grade III PN. No grade IV PN was reported. Most early-onset PN events were grade I, and treatment-related grade III PN occurred in 7% of patients who received up to three cycles of nab-P. Of those who developed grade III PN with nab-P/Gem treatment, 30 (43%) improved to grade ≤I (median time to improvement = 29 days) and 31 (44%) resumed therapy. Development of PN was associated with efficacy; median overall survival in patients with grade III versus 0 PN was 14.9 versus 5.9 months (hazard ratio, 0.33; P < .0001). Conclusions nab-P/Gem was associated with grade III PN in a small percentage of patients. PN development was associated with longer treatment duration and improved survival. Grade III PN was reversible to grade ≤I in many patients (median ≈ 1 month) NCT00844649.
