Abstract
Intravenous liposomal irinotecan injection (Onivyde) is approved for use in combination with 5-fluorouracil and leucovorin (5-FU/LV) in patients with metastatic pancreatic adenocarcinoma that has progressed following gemcitabine-based therapy. Liposomal irinotecan is a liposome-encapsulated formulation of the topoisomerase-1 inhibitor irinotecan, developed to overcome the pharmacological and clinical limitations of non-liposomal irinotecan. The objective response rate was also significantly higher in the liposomal irinotecan plus 5-FU/LV group than in the control group. Liposomal irinotecan-based combination therapy had a manageable safety profile; the most common treatment-emergent adverse events (TEAEs) of grade 3 severity were haematological or gastrointestinal in nature. The incidence of neutropenic sepsis was low. In a setting where there is a paucity of second-line treatment options, liposomal irinotecan in combination with 5-FU/LV is an important emerging treatment option for metastatic adenocarcinoma of the pancreas that has progressed following gemcitabine-based therapy.
