NaliCap (Irinotecan Liposome (Nal-IRI)/Capecitabine) vs. NAPOLI (Nal-IRI/5-FU/LV) ) in Advanced Pancreatic Cancer

* At the time of initial diagnosis of pancreatic cancer, resectable pancreatic cancer is around 20%, locally-advanced pancreatic cancer is around 25-30%, and the remaining is metastatic pancreatic cancer. * In metastatic pancreatic cancer, Gemcitabine/Abraxane or FOLFIRINOX 5-fluorouracil/leucovorin/irinotecan/oxaliplatin (FOLFIRINOX) is most commonly used regimen as a palliative 1st-line chemotherapy. In gemcitabine-pretreated pancreatic cancer, irinotecan liposome(nal-IRI)/5-fluorouracil(5FU)/leucovorin(LV)(NAPOLI regimen) improved overall survival of patients compared to 5FU/LV. Now, NAPOLI is standard of care in gemcitabine-pretreated pancreatic cancer. * Oral 5-FU such as TS-1 is used in gemcitabine pretreated pancreatic cancer patients or 1st-line treatment in gemcitabine-intolerable patients. * Capecitabine is oral 5-FU, which is commonly used in GI cancers, usually replacing intravenous infusion of 5-FU. It improves patient's convenience not requiring vascular access or hospital admission. * In NAPOLI regimen, iv 5-FU/LV could be replaced with capecitabine. So far, nal-IRI/Capecitabine combination has not yet been tested. * Based on these rationale, we plan to conduct the open-label, randomized phase 2 study to assess the safety and efficacy of NaliCap (nal-IRI/Capecitabine) compared to NAPOLI (nal-IRI/5-FU/LV) in patients with gemcitabine-pretreated advanced pancreatic cancer.
