Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will be eligible for inclusion if their primary tumors have been resected and if the patients have histologically confirmed wild-type-KRAS colorectal adenocarcinoma with synchronous liver-confined metastases deemed non-resectable. Eligible patients will be randomly assigned to chemotherapy plus cetuximab (arm A) or chemotherapy alone (arm B). Treatment will be planned to commence between 2 and 4 weeks after the primary surgery. 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 2 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.

Phase

Phase

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.

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
the rate of patients converted to resection for liver metastases
Time Frame: 3 years
To explore whether cetuximab in combination with chemotherapy as treatment could improve the resection rate in patients with KRAS wild-type, unresectable colorectal liver-limited metastases compared with chemotherapy alone.
3 years

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
Time Frame
progression free survival
Time Frame: 3 years
PFS will be defined as the period from the first day of cetuximab 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.
3 years
overall survival
Time Frame: 3 years
OS and MST 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 years
tumor response
Time Frame: 3 years
defined as partial and complete response according to RECIST 1.0 (Response Evaluation Criteria in Solid Tumors).
