Detailed Description

This was a single-arm, prospective study to investigate the safety of cetuximab in combination with trifluridin tipiracil (TAS-102) in the third-line treatment of Chinese patients with RAS wild-type mCRC. Cetuximab will be administered at a fixed dose of 500 mg/m2 once every 2 weeks; trifluridin tipiracil will be administered in a dose de-escalation design: dose level 1: 35 mg/m2 twice daily on days 1-5 once every 2 weeks; after 1 cycle will be observed, and if ≤ 2 patients experience DLT, this dose level will be the recommended phase II dose; if ≥ 3 patients experience DLT, additional 6 patients will receive dose level 0. ( Dose level 0: 30 mg/m2, twice daily, Days 1-5, once every 2 weeks;) If ≤ 2 individuals experience DLT, this dose level is the recommended Phase II dose; if ≥ 3 individuals experience DLT, the study will be stopped.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years to 75 years (ADULT, OLDER_ADULT)

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
Incidence of DLT（Dose-limited toxicity）
Time Frame: From Baseline to primary completion date, about 18 months
Determination of RP2D based on incidence of DLT
From Baseline to primary completion date, about 18 months

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.
