Bioequivalence Study of Irinotecan Liposome Injection in Chinese Advanced Pancreatic Cancer.

*Official Title: Randomized, Open-label, Single-dose, Two-sequence, Two-period, Crossover Bioequivalence Trial of Irinotecan Liposome Injection in Patients With Advanced Pancreatic Cancer.

Randomized, Open-label, Single-dose, Two-sequence, Two-period, Crossover Bioequivalence Trial of Irinotecan Liposome Injection in Patients With Advanced Pancreatic Cancer.

The purpose of this study was to determine the bioequivalence of two formulations of Irinotecan Liposome Injection (70mg/m2) in Chinese patients with Advanced Pancreatic Cancer, under fasting condition. These data were to be evaluated statistically to determine if the products meet bioequivalence criteria.

2. Advanced pancreatic cancer diagnosed by histopathology and / or cytology.
3. Age ≥ 18 years, men or women. BMI is above 17.

8. Adequate renal function.
9. Patient with reproductive potential must agree to use adequate contraception from the signing of informed consent to at least 6 months after the trial

6. Patients who currently enrolled in any other clinical study, or received other investigational agents within 4 weeks of the first dose of the study drug；
7. Blood donation or massive blood loss (>400mL) within 90 days of screening;
8. Concomitant use of strong CYP3A4 inhibitors or inducers, or UGT1A1 inhibitors within 4 weeks of the first dose of the study drug;
9. Patients who received certain diet (such as grapefruit) which may interfere with the evaluation of PK results;
10. LVEF≤50%;
11. Patients with extended QT/QTc interval (QTcF>480ms);
12. History of alcohol or drugs abuse;
