Avastin in Combination With Chemotherapy for RAS Mutant Unresectable Colorectal Liver-limited Metastases

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01972490

Brief Summary:
In this study, the investigators assessed the effect of avastin in combination with chemotherapy in the treatment of RAS mutant-type, unresectable colorectal liver-limited metastases

Condition or disease Intervention/treatment Phase
Colorectal Neoplasms Drug: avastin Drug: mFOLFOX6 Phase 4

Detailed Description:
Patients will be eligible for inclusion if the patients have histologically confirmed colorectal adenocarcinoma with RAS mutant liver-confined metastases deemed non-resectable. Eligible patients will be randomly assigned to chemotherapy plus avastin (arm A) or chemotherapy alone (arm B). Treatment will continue until tumor response indicates suitability for surgery for liver metastases or until disease progression or unacceptable toxic effects. The primary endpoint is the conversion rate to radical resection for liver metastases,which will be assessed by local multidisciplinary team (includes more than three liver surgeons and one radiologist) with the use of contrast-enhanced CT or MRI after 4 cycles and then every other 4 cycles up to 12 cycles. To provide an objective assessment of changes in resectability, radiological images will be presented by a radiologist to more than 3 liver surgeons, who are blinded to the clinical data. Patients will be considered resectable if 50% or more of surgeons vote for radical resection of LM. For patients whose liver-metastases are assessed resectable, resection should be scheduled to be performed within 2~3 weeks of the last treatment cycle. Following resection, patients will be advised to continue the same therapeutic regimen until the treatments reach a sum of 12 cycles.

Actual Enrollment : 241 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Study of Avastin in Combination With Chemotherapy for the First Line Treatment of RAS Mutant Unresectable Colorectal Liver-limited Metastases
Actual Study Start Date : October 2013
Actual Primary Completion Date : December 2017
Actual Study Completion Date : June 2019

Arm Intervention/treatment
Experimental: ARM A
patients received avastin in combination with mFOLFOX6
Drug: avastin
Drug: avastin On day 1 of a 14 day treatment cycle, patients received a 2-hour infusion of avastin (5mg/kg) followed by chemotherapy of mFOLFOX6 until progressive disease or unacceptable toxicity.
Other Name: Bevacizumab

Drug: mFOLFOX6
mFOLFOX-6 (oxaliplatin, 85mg/m2 on day 1 infused during 2 hours;LV400mg/m2 on days 1 infused during 2 hours, followed by FU 400 mg/m2 intravenous bolus then 2400 mg/m2 continuous infusion for 46 hours)

Active Comparator: ARM B
Patients received mFOLFOX6 alone
Drug: mFOLFOX6
mFOLFOX-6 (oxaliplatin, 85mg/m2 on day 1 infused during 2 hours;LV400mg/m2 on days 1 infused during 2 hours, followed by FU 400 mg/m2 intravenous bolus then 2400 mg/m2 continuous infusion for 46 hours)

Primary Outcome Measures :
  1. the rate of patients converted to resection for liver metastases [ Time Frame: 3 years ]
    To explore whether avastin in combination with chemotherapy as treatment could improve the resection rate in patients with RAS mutant-type, unresectable colorectal liver-limited metastases compared with chemotherapy alone.

Secondary Outcome Measures :
  1. progression free survival [ Time Frame: 3 years ]
    PFS will be defined as the period from the first day of avastin treatment or chemotherapy to the date of disease progression (PD) or to death. Patients without PD who discontinued the study for any reason is censored at the last on-study tumor assessment date.or distant(i.e. metastasis) disease recurrence or death.

  2. overall survival [ Time Frame: 3 years ]
    OS will be calculated from randomization to death from any cause or the date of the last follow-up, at which point the data will be censored.

  3. tumor response [ Time Frame: 3 years ]
