In an open-label, single-arm phase Ib dose-escalation trial, 7 of 18 patients (39%) treated with various doses of ADI-PEG 20 combined with nab-paclitaxel and gemcitabine experienced partial response (PR) per RECIST v1.1 criteria, and 10 patients (56%) had stable disease (SD), according to data presented at the 2017 Gastrointestinal Cancers Symposium in San Francisco.1 Seven patients experienced ≥3 toxicity that was considered to be potentially caused by ADI-PEG 20, including neutropenia in 4 patients.
