Quintuple Method for Treatment of Multiple Refractory Colorectal Liver Metastases

March 7, 2023 updated by: Liaoning Tumor Hospital & Institute

A Prospective, Single-arm, Single-center, Phase II Clinical Trial to Evaluate the Efficacy of Quintuple Method for the Treatment of Multiple Refractory Colorectal Liver Metastases

The aim of this study is to explore the therapeutic effect of Quintuple method in the treatment of patients with multiple and refractory liver metastases from colorectal cancer. A randomized single-arm clinical trial was conducted.The intervention group was treated with single SOX chemotherapy, SOX chemotherapy combined with cetuximab targeted therapy, SOX chemotherapy combined with low-dose cetuximab targeted therapy combined with three-drug regimen（Quintuple method）, and the RECIST 1.1 solid tumor evaluation criteria were used to assess the disease.

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

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 with inoperable colorectal liver metastases were selected for genetic testing and enrolled if Kras/Nras/Braf wild-type was detected. The enrolled patients were randomly divided into three groups, in which patients in the single chemotherapy group were treated with SOX regimen alone for chemotherapy;patients in the chemotherapy targeted group were treated with SOX regimen chemotherapy combined with cetuximab targeted therapy; patients in the Quintuple method group were treated with SOX regimen chemotherapy,cetuximab targeted therapy and folic acid, vitamin A, and metronidazole three-drug regimen. Specific drugs were administered at the following doses: SOX regimen every 3 weeks, oxaliplatin via intravenous drip on d1 at a dose of 130 mg/m2 × patient 's body surface area, and S1 orally on d2-d15 at 20 mg three times daily. Cetuximab combined with chemotherapy was administered simultaneously, once every three weeks, and intravenous drip was performed before oxaliplatin at a dose of 250 mg/m2 × body surface area. Metronidazole 0.4 g/time, qd; vitamin A 5,000 units/time, qd; folic acid 5 mg/time, qd. The latter three drugs were continued until the end of all chemotherapy cycles.Tumor markers associated with liver metastases from colorectal cancer,including magnetic resonance imaging and computed tomography, wererepeated every 3 months and disease was assessed using RECIST 1.1 criteria for the evaluation of solid tumors. The primary end point was death, and the secondary end point was disease progression.

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
Overall Response Rate (ORR)
Time Frame: Up to approximately 2 years
Overall response rate (ORR) is defined as the proportion of patients with the best overall response of complete response (CR) or partial response (PR) according to RECIST 1.1
Up to approximately 2 years
Overall Survival (OS)
Time Frame: Up to approximately 2 years
OS is the time interval from the start of treatment to death due to any reason or lost of follow-up. For subjects who survived or were lost to follow-up by the data analysis cutoff date, survival was truncated by the subject's last known survival time
Up to approximately 2 years
Progression Free Survival (PFS)
Time Frame: Up to approximately 2 years
PFS is defined as the time from the date of randomization to the date of the first documented progression or death due to any cause.
Up to approximately 2 years
