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

  • 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
Overall survival (OS)
Time Frame: up to 42 months
OS was defined as the time from date of randomization until death from any cause
up to 42 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.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival (PFS)
Time Frame: up to 42 months
PFS was defined as the time from date of randomization until first objective radiographic tumor progression or death from any cause, based on Investigator assessment
up to 42 months
Objective response rate (ORR)
Time Frame: up to 42 months
ORR is defined as the proportion of subjects achieving the best overall response (BOR) of CR or PR. BOR refers to the best response recorded during the period from the date of randomization to the date of objective progression documented according to RECIST 1.1 criteria or the date of initiation of subsequent antitumor therapy (whichever occurs first).
up to 42 months
Duration of response (DOR)
Time Frame: Time from initial response (CR or PR) to date of documented disease progression or death (due to any cause) whichever occurs first, up to 42 months
defined time from the initial response (CR or PR) until documented tumor progression or death from any cause and based on Investigator assessment.
Time from initial response (CR or PR) to date of documented disease progression or death (due to any cause) whichever occurs first, up to 42 months
Disease control rate (DCR)
Time Frame: From start of treatment to date of documented disease progression, up to approximately 42 months
defined as the proportion of participants who achieved CR, PR, or stable disease (SD) , based on Investigator assessment.
From start of treatment to date of documented disease progression, up to approximately 42 months
Incidence of adverse events (AEs)
Time Frame: up to 42 months
up to 42 months
