A Phase III, Open-label, Randomized Study of the Combination Therapy With NC-6004 and Gemcitabine Versus Gemcitabine Alone in Patients With Locally Advanced or Metastatic Pancreatic Cancer
A Phase III, Open-label, Randomized Study of the Combination Therapy With NC-6004 and Gemcitabine Versus Gemcitabine Alone in Patients With Locally Advanced or Metastatic Pancreatic Cancer
This clinical trial is designed to evaluate the impact of the addition of NC-6004 to gemcitabine in the treatment of patients with locally advanced or metastatic pancreatic cancer in Asian countries.
Pancreatic cancer is one of the most deadly cancers because of the predominately late diagnosis. Gemcitabine (GEM) is the standard treatment for advanced and metastatic pancreatic cancer. According to preclinical data and few early phase studies, a combined use of gemcitabine and cisplatin (CDDP) showed synergistic efficacy against pancreatic cancer. NC-6004, a novel micellar cisplatin formulation, retains the activity but avoids the renal toxicity and neurotoxicity caused by the high peak Cmax concentrations of cisplatin. This trial is designed to evaluate the impact of the addition of NC-6004 to gemcitabine in the treatment of patients with locally advanced or metastatic pancreatic cancer.
The main hypothesis of this study is that NC-6004 plus gemcitabine combination is superior to gemcitabine alone in terms of overall survival in locally advanced or metastatic pancreatic cancer patients

Patient with active hepatitis B, hepatitis C or any other ongoing severe infections
Patient with severe mental disorder
As judged by the investigator, any evidence of significant laboratory findings or severe/uncontrolled clinical disorders (e.g. dementia, myocardial infarction within 6 months prior to enrollment, New York Heart Association (NYHA) Class III or IV heart failure, unstable angina, active cardiomyopathy, unstable arrhythmia, and other unstable or uncompensated respiratory, cardiac, hepatic, renal and/or infectious disease)

Observation of "attenuated or reversed hepatic venous portal blood flow*" was confirmed by doppler ultrasonography or CT (recommend evaluation in arterial phase, portal-venous phase and equilibrium phase) of the liver * On doppler ultrasonography of right and left branch of portal vein, blood flow is measured as about 0 mL/min or between plus and minus, which indicate obvious blood flow obstruction
