Efficacy of FOLFOX Versus FOLFOX Plus Aflibercept in K-ras Mutant Patients With Resectable Liver Metastases (BOS3)

May 8, 2017 updated by: European Organisation for Research and Treatment of Cancer - EORTC

BOS3: Randomized Phase II/III Trial Evaluating the Efficacy of FOLFOX Alone Versus FOLFOX Plus Aflibercept in K-ras Mutant as Perioperative Treatment in Patients With Resectable Liver Metastases From Colorectal Cancer.

Patients presenting with multiple innumerable liver metastases will probably never come to resection, however, for all others, including patients with numerous multiple metastases or large metastases, resection should be considered after limited chemotherapy.

There is consensus for a backbone chemotherapy consisting of fluoropyrimidine + oxaliplatin. FOLFOX was used in the previous EORTC study and is again recommended.

The addition of targeted agents to standard chemotherapy in the perioperative strategy for mCRC might increase the ORR and R0 resectability, without significant increase in toxicity, therefore translating to a better outcome.

BOS2 (EORTC 40091) was designed to test this hypothesis in patients with a KRAS wold-type profile.

It was decided in parallel to design an open label, randomized, multi-center, 2-arm phase II-III study this time aimed at enrolling KRAS mutated patients.

Arm A: (standard) mFOLFOX6 + Surgery Arm B: (experimental) mFOLFOX6 + Aflibercept + Surgery

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Inclusion Criteria:

  • Histologically proven CRC with 1 to 8 metachronous or synchronous liver metastases considered to be completely resectable
  • Primary tumor (or liver metastasis) of CRC must be KRAS status "mutant"
  • Patients must have undergone complete resection (R0) of the primary tumor at least 4 weeks before randomization. Or for patients with synchronous metastases the primary tumor can be resected (R0) at the same time as the liver metastases if: the patient has a non-obstructive primary tumor and is able to receive preoperative chemotherapy (3-4 months) before surgery1.
  • Measurable hepatic disease by RECIST version 1.1
  • Patients must be 18 years old or older
  • A World Health Organization (WHO) performance status of 0 or 1
  • Previous adjuvant chemotherapy for primary CRC is allowed if completed at least 12 months before inclusion in this study
  • All the following tests should be done within 4 weeks prior to randomization:
  • Hematological status: neutrophils (ANC) = 1.5x10 9/L; platelets = 100x10 9/L; haemoglobin = 9g/dL
  • Serum creatinine = 1.5 times the upper limit of normal (ULN)
  • Proteinuria < 2+ (dipstick urinalysis) or =1g/24hour.
  • Liver function: serum bilirubin = 1.5 x upper normal limit (ULN), alkaline phosphatase < 5xULN
  • Magnesium ≥ lower limit of normal (LLN)
  • Patients with a buffer range from the normal values of +/- 5% for hematology and +/- 10% for biochemistry are acceptable. This will not apply for Renal Function, including Creatinine.
  • Women of child bearing potential (WOCBP) must have a negative serum (or urine) pregnancy test within 14 days prior to the first dose of study treatment.
  • Patients of childbearing / reproductive potential should use adequate birth control measures, as defined by the investigator, during the study treatment period and for at least 6 months after the last study treatment. A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly.
  • Female subjects who are breast feeding should discontinue nursing prior to the first dose of study treatment and until 6 months after the last study treatment.
  • Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
  • Patient should be willing and able to comply with protocol requirements
  • Before patient registration/randomization, written informed consent must be given according to ICH/GCP, and national/local regulations.

Exclusion Criteria:

  • Evidence of extra-hepatic metastasis (of CRC)
  • Previous chemotherapy for metastatic disease or surgical treatment (e.g. surgical resection or radiofrequency ablation) for liver metastasis. Radiotherapy alone is allowed if given pre or post protocol treatment
  • Previous exposure to VEGF/VEGFR targeting therapy within the last 12 months
  • Major surgical procedure, open biopsy, or significant traumatic injury within 4 weeks prior to randomization
  • Gilbert's syndrome
  • History of myocardial infarction and/or stroke within 6 months prior to randomization
  • Uncontrolled hypertension (defined as systolic blood pressure >150 mmHg and/or diastolic blood pressure > 100 mmHg), or history of hypertensive crisis, or hypertensive encephalopathy
  • History or evidence upon physical examination of CNS metastasis
  • Bowel obstruction
  • Uncontrolled hypercalcemia
  • Pre-existing permanent neuropathy (NCI grade = 2)
  • Known allergy to any excipient to study drugs

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: 1 year
Increase in progression free survival rate at 1 year in the experimental arm (mFOLFOX6 + aflibercept) compared to mFOLFOX6 alone arm.
1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Pathological response rate
Time Frame: 4 years
Increase in major pathological response rate between mFOLFOX6 alone arm and each experimental arm.
4 years
Resection rate

Overall survival
Time Frame: 8 years
Overall survival is defined as the time interval between the date of randomization and the date of death. Patients who are still alive when last traced will be censored at the date of last follow-up.
8 years
