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

14 years and older (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
Disease Control Rate (DCR )
Time Frame: up to 36 months
DCR is defined as the percentage of patients who have achieved complete response, partial response and stable disease lasting for at least 6 months from therapy start. DCR will be evaluated using the new international criteria proposed by the Version 1.1 Response Evaluation Criteria in Solid Tumors (RECIST).
up to 36 months
Incidence of Treatment-Emergent Adverse Events
Time Frame: up to 30 days after the last treatment cycle
The evaluation of the Incidence of Treatment-Emergent Adverse Events starts from the 1st treatment until 30 days after the last treatment cycle; Treatment-Emergent Adverse Events are evaluated according to version 4.03 CTC-AE criteria.
up to 30 days after the last treatment cycle

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 (PFS)
Time Frame: up to 36 months
PFS is defined as the time from the start treatment date to the date of first observation of documented disease progression or death due to any cause. Patients without tumor progression at the time of analysis will be censored at their last date of tumor evaluation.
up to 36 months
Overall survival (OS)
Time Frame: up to 36 months
Overall survival is defined as the time from the therapy start to the date of death due to any cause or the date of last contact (censored observation) at the date of data cut-off.
up to 36 months
