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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

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

Time Frame
Treatment related adverse events (TRAEs)
Time Frame: Up to 30 days after last treatment
The incidence and severity of TRAEs graded according to NCI-CTCAE v5.0

Objective Response Rate
Time Frame: Up to approximately 2 years
Objective response rate (ORR) is the proportion of subjects with complete response (CR) or partial response (PR), based on RECIST v1.1
Up to approximately 2 years

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
Disease control rate (DCR)
Time Frame: Up to approximately 2 years
DCR is defined as the proportion of subjects with CR, PR, or stable disease(SD) based on RECIST v1.1.
Up to approximately 2 years
Overall survival (OS)
Time Frame: Up to approximately 2 years
OS is the time from the date of first dosing date to death due to any cause.
Up to approximately 2 years
Duration of response (DoR)
