About

Hepatic artery infusion chemotherapy (HAIC) have shown promising outcomes in patients with advanced hepatocellular carcinoma (HCC).In China, Oxaliplatin combined with 5-fluorouracil is commonly used in continuous hepatic arterial perfusion chemotherapy.But the 5-FU requiring a long infusion and Calcium folate is also needed to sensitize 5-FU. Moreover, 5-FU regimen was associated with a variety of adverse events, which limited its application in HAIC.Compared to 5-fluorouracil, raltetrexed is less toxic, has a stronger anti-tumor effect and can be administered in just two to three hours. However, the comparison of the two drugs in HAIC to treat advanced HCC has not been reported. In this study, we will evaluate the the progression-free survival(PFS)、objective response rate（ORR）、 disease vacancy rate（DCR）、overall survival (OS) and safety in patients with advanced hepatocellular carcinoma (Ad-HCC) who are undergoing hepatic arterial infusion (HAI) of Raltetrexed plus oxaliplatin (SALOX) compared with oxaliplatin, fluorouracil/leucovorin (FOLFOX) treatment by designing prospective, multi-center phase III clinical study.

Full description

Femoral artery puncture and catheterization were performed in every cycle of treatment,a micro-catheter was inserted and located in feeding hepatic artery. The therapeutic scheme was that, the experimental group SALOX regimen including oxaliplatin (130 mg/m2 infusion for 3 hours on day 1) and raltetrexed (2mg/m2 for 30 to 60 minutes on day 1) . The control group modified FOLFOX6 regimens including oxaliplatin (130 mg/m2 infusion for 3 hours on day 1), leucovorin (200 mg/m2 from hour 3 to 5 on day 1) and Fluorouracil (400 mg/m2 in bolus, and then 2,400 mg/m2 continuous infusion 46 hours). All chemo-drugs were given by HAI. Treatment was repeated every 3 weeks and continued until intrahepatic lesions progression or unacceptable toxicity.Enhanced CT or MRI was performed every 6 weeks after treatment begins. Routine follow-up intervals were 2-4 months.

Inclusion criteria

• Provision of signed and dated, written informed consent form (ICF) and any locally required authorization obtained from the patient prior to any mandatory study specific procedures, sampling, and analyses.
• Provision of signed and dated written genetic informed consent prior to optional collection of sample for genetic analysis.
• Patients with BCLC stage C hepatocellular carcinoma confirmed by pathology or clinically diagnosed
• Age ≥18 years and < 75 years at the time of screening.
• Portal vein invasion or extrahepatic oligosaccharides were detected by baseline imaging. Oligosaccharides were defined as no more than two extrahepatic organs and no more than three tumors.
• Child-Pugh score class A to B
• No local antitumor therapy for hepatocellular carcinoma was received within 4 weeks prior to enrollment
• No previous systemic antitumor therapy for hepatocellular carcinoma
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 at enrollment
• The expected survival time is no less than 3 months
• Patients with HBV infection, which is characterized by positive hepatitis B surface antigen (HBsAg) and/or hepatitis B core antibodies (anti-HBcAb) with detectable HBV DNA (≥10 IU/ml or above the limit of detection per local lab standard), must be treated with antiviral therapy, as per institutional practice. HBV antiviral therapy must be initiated prior to randomization and patients must remain on antiviral therapy for the study duration and for 6 months after the last dose of study medication. Patients must show evidence HBV stabilization or signs of viral response (e.g., reduction HBV DNA levels) prior to starting IP. Patients who test positive for anti-hepatitis B core (HBc) with undetectable HBV DNA (<10 IU/ml or under the limit of detection per local lab standard) do not require anti-viral therapy prior to randomization. These subjects will be tested at every cycle to monitor HBV DNA levels and initiate antiviral therapy if HBV DNA is detected (≥10 IU/ml or above the limit of detection per local lab standard). HBV DNA detectable subjects must initiate and remain on antiviral therapy for the study duration and for 6 months after the last dose of study medication.
• Patients with HCV infection must have management of this disease per local institutional practice throughout the study. HCV diagnosis is characterized by the presence of detectable HCV ribonucleic acid (RNA) or anti-HCV antibody upon enrollment.
• At least 1 measurable intrahepatic lesion suitable for repeat assessments according to the following mRECIST criteria: （1）Liver lesions that show typical features of HCC on IV contrast-enhanced CT or MRI scans, ie, hypervascularity in the arterial phase with washout in the portal or the late venous phase；（2）Viable, non-necrotic portion (arterial phase IV contrast-enhancing) that can be accurately measured at baseline as ≥10 mm in the longest diameter.
