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.

  9. Patients who are under biologic treatment for their malignancy

  10. Laboratory tests (hematology, chemistry) outside specified limits:

    1. WBC ≤ 3 x 10³/mm³
    2. ANC ≤ 1.5 x 10³/mm³
    3. Platelets ≤ 100.000/mm³

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
progression free survival (PFS)
Time Frame: Since this is an exploratory trial, it takes a sample size of 61 patients per arm entered in 2 years with a minimum 1 year of follow up to reach 75% power with type I error of 10% under the assumptions of exponential survival functions.
The 6-month PFS rates of the two arms are assumed to be 60% (SLOG) vs. 45% (mFOLFIRINOX)
Since this is an exploratory trial, it takes a sample size of 61 patients per arm entered in 2 years with a minimum 1 year of follow up to reach 75% power with type I error of 10% under the assumptions of exponential survival functions.
