Summary

This trial is to compare the efficacy and safety of modified FOLFOX6 \[mFOLFOX6, a specific chemotherapy regimen of Oxaliplatin ,5-Fluorouracil and Leucovorin\] chemotherapy plus Antigen Pulsed Dendritic Cells (APDC，a kind of autologous tumor lysates pulsed human dendritic cells vaccine) with modified chemotherapy alone in patients with metastatic colorectal cancer.

Detailed description

Metastatic colorectal cancer (CRC) patients will be randomly assigned (3:1) to receive either modified FOLFOX6 \[mFOLFOX6\] chemotherapy combined with Antigen Pulsed Dendritic Cells (Arm APDC + Chemotherapy), or chemotherapy alone (Arm Chemotherapy). Each patient recruited in the study will receive maximum 12 cycles of (14 days/cycle) mFOLFOX6 chemotherapy. Patients in Arm APDC + Chemotherapy will receive APDC vaccination in addition to chemotherapy in the cycle 1-3 and 7-9, and in cycle 4-6 and 10-12 receive only chemotherapy. APDC + Chemotherapy or Chemotherapy will be stopped in case of disease progression, intolerable toxicities, or patient withdrawal with the consent. After 12 cycles, patients in Arm APDC + Chemotherapy will receive 5-Fluorouracil treatment plus every 3 months APDC therapy and patients in Arm Chemotherapy will receive only 5-Fluorouracil treatment. PFS, ORR and OS will be assessed, and toxicity and immunologic effects will be monitored.

Conditions

• Metastatic Colorectal Cancer

Interventions

Type	Name	Description
BIOLOGICAL	APDC + Chemotherapy	Patients in Arm APDC+Chemotherapy receive maximum 12 cycles (14days/cycle) mFOLFOX6 chemotherapy. Each cycle chemotherapy consist of Oxaliplatin at 85mg/ m2 infused for 2 hours only on day 1,and Leucovorin at 400 mg/m2 was administered intravenously for 2 hours, followed by continuous intravenous administration of 5-Fluorouracil at 400 mg/m2 (2.4g/m2 for 46 hours).On day 8 of cycle1-3 and 7-9, patients also receive APDC vaccine infusion in 100ml saline. After 12 cycles, patients in Arm APDC+chemotherapy will receive 5-Fluorouracil /Leucovorin (Leucovorin at 400 mg/m2/day administered intravenously for 2 hours, intravenous bolus of 5-Fluorouracil at 400 mg/m2 , followed by continuous intravenous administration of 5-Fluorouracil at 1200 mg/m2/d for 2 days, repeated every 2 weeks) plus APDC therapy (once every 3 months). Treatments will continue unless disease progression, intolerable toxicity or patients withdrawal).
DRUG	Chemotherapy	Patients in Arm Chemotherapy receive maximum 12cycles (14days/cycle) mFOLFOX6 chemotherapy. Each cycle chemotherapy consist of Oxaliplatin at 85mg/ m2 infused for 2 hours only on day 1, and Leucovorin at 400 mg/m2 was administered intravenously for 2 hours, followed by continuous intravenous administration of 5-Fluorouracil at 400 mg/m2 (2.4g/m2 for 46 hours). After 12 cycles, patients in Arm chemotherapy will receive only 5-Fluorouracil /Leucovorin (Leucovorin at 400 mg/m2/day administered intravenously for 2 hours, intravenous bolus of 5-Fluorouracil at 400 mg/m2 , followed by continuous intravenous administration of 5-Fluorouracil at 1200 mg/m2/d for 2 days, repeated every 2 weeks). Treatments will continue unless disease progression, intolerable toxicity or patients withdrawal).
