Brief Summary:
This is a randomized, double-blind, placebo-controlled multi-center phaseⅢstudy to evaluate efficacy and safety of oxaliplatin-based chemotherapy plus MB-6(320 mg/capsule, 6 capsules tid) in patients with stage 3 colorectal cancer who underwent surgical excision of their primary tumor.

Condition or disease Intervention/treatment
Stage III Colorectal Cancer Neutropenia Drug: MB-6 Drug: Placebo

Detailed Description:
The investigational new drug, MB-6, in the proposed clinical trial is to be used as an adjuvant therapy for metastatic colorectal cancer patients. All of six extracts have been used in human with a long history, and many literatures reported the medicinal use either individually or as ingredients of formulations. MB-6 may provide its therapeutic benefits via inhibition of tumor induction or enhancing the efficacy of chemotherapy in colorectal cancer.

Primary Outcome Measures :
  1. The primary endpoint is the incidence of grade 4 neutropenia during the chemotherapy period, defined as an absolute neutrophil count (ANC) <500/mm3. [ Time Frame: 18 weeks ]
    The primary endpoint is the incidence of grade 4 neutropenia during the chemotherapy, defined as an absolute neutrophil count (ANC)<500/mm3

Secondary Outcome Measures :
  1. Time to first Grade 4 Neutropenia [ Time Frame: 18 weeks ]

    To determine the time interval from randomization to the first episode of grade 4 Neutropenia.

    The analyses for incidence of study event will be conducted using logistic regression model method to adjust for gender and the regimen of chemotherapy (e.g., FOLFOX4 or FOLFOX6).

  2. Incidence of Febrile Neutropenia [ Time Frame: 18 weeks ]
    The febrile neutropenia is defined as an ANC <1000/mm3 and a single temperature ≥38.3 degree of C or a sustained temperature of ≥38.0 degree C for more than one hour.

  3. Incidence of Grade 3 or 4 Neutropenia [ Time Frame: 18 weeks ]
    The grade 3 or 4 neutropenia during the chemotherapy period is defined as an absolute neutrophil count (ANC) <1000/mm3.

  4. Change in Serum Creatinine level [ Time Frame: 18 weeks ]
    Any change in Serum Creatinine level during the chemotherapy period

  5. Health-Related Quality of Life (HRQoL) - QLQ-C30 [ Time Frame: 18 weeks ]
    Health-Related Quality of Life (HRQoL) - QLQ-C30 should be completed at baseline, day 71 and end of study.

  6. Quality of Life -VAS on Fatigue, Constipation, Appetite [ Time Frame: 18 weeks ]
    Quality of Life -VAS on Fatigue, Constipation, Appetite will be assessed by patients every two weeks until end of study.

  7. Compliance with Chemotherapy [ Time Frame: 18 weeks ]
    The compliance with chemotherapy will be summarized by descriptive statistic and listed by each cycle and overall period.

  8. Increase in Body Weight [ Time Frame: 18 weeks ]
    Any increased body weight during the chemotherapy period.
