Details and patient eligibility


This is a multicenter, randomized, open-lable, parallel-controlled phase II study of irinotecan liposome injection-containing regimens versus nab-paclitaxel plus gemcitabine in patients with previously untreated, metastatic pancreatic adenocarcinoma. The purpose of this study is to evaluate the differences of safety and efficacy of irinotecan liposome injection-containing regimens versus nab-paclitaxel plus gemcitabine in patients with previously untreated, metastatic pancreatic adenocarcinoma.

Full description

This is a multicentre randomized, open-label, parallel-controlled, phase II study to evaluate the efficacy and safety of irinotecan liposome injection-containing regimens. Eligible patients will be randomly divided into two cohorts at a ratio of 2:1. The patients in cohort 1 (the experimental group) will receive irinotecan liposome injection combined with 5-fluorouracil (5-FU), leucovorin (LV) and oxaliplatin.The patients in cohort 2 (the control group) will receive nab-paclitaxel plus gemcitabine.

  10. Activated Partial Thromboplastin Time (APTT), International Normalized Ratio (INR) and prothrombin time (PT) ≤1.5 × ULN for patients not receiving therapeutic anticoagulation.

  11. According to the related guidelines, patients with HBV DNA or HBsAg and/or anti-HBC positive must receive prophylactic treatment (at least one week before the initial administration of the study drug) and take antiviral drugs in stable dose (e.g., entecavir, tenofovir, or lamivudine; No adefovir or interferon are allowed) at study entry with planned monitoring and management, including baseline HBV DNA levels. Patient receiving active hepatitis C virus (HCV) treatment must use astable dose of drugs at study entry and be subject to planned monitoring and management according to antiviral drug guidelines;

  12. Female patients with reproductive potential must agree to use adequate contraception from the signing of informed consent to at least 6 months after the study completion and have a negative serum pregnancy test within 3 days before enrollment, and must be non-lactating. Male patients must agree to use medically approved contraception during the study period and for 6 months after the study completion;

  13. Ability to understand and the willingness to sign a written informed consent.
