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

A new oral DPD inhibitory fluoropyrimidine (DIF), S-1, is reportedly effective against gastrointestinal carcinoma. In this study, the relationship between activity of DPD in peripheral blood and the effects of chemotherapy were investigated in 200 patients treated with first-line S-1 combined with platinum chemotherapy for gastrointestinal carcinoma.

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.

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
Objective tumor response
Time Frame: Every eight weeks
Tumor response was evaluated by RECIST 1.1. The relationship between DPD activity and the objective tumor response will be evaluated by Cox's proportional hazards regression model.
Every eight weeks

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
Overall survival
Time Frame: Three year
The relationship between DPD activity and the overall survival will be evaluated by Cox's proportional hazards regression model.
Three year
Progress-free survival
Time Frame: one year
The relationship between DPD activity and the PFS will be evaluated by Cox's proportional hazards regression model.
one year
Adverse event incidence
Time Frame: One year
The relationship between DPD activity and the drug-related toxicity incidence will be evaluated by Cox's proportional hazards regression model.
One year
