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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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
Number of Participants With Adverse Events (AE) by Severity According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0
Time Frame: Up to 3 years and 5 months
An AE is any untoward medical occurrence in a participant administered a pharmaceutical (investigational or non-investigational) product. It does not necessarily have a causal relationship with the investigational product. The severity of AEs has 5 grades based on NCI-CTCAE version 5.0 criteria: Grade 1: Mild; Grade 2: Moderate; Grade 3: Severe; Grade 4: Life-threatening consequences; Grade 5: Death.
Up to 3 years and 5 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
Percentage of Participants With Overall Response (OR)
Time Frame: Up to 3 years and 5 months
The percentage of participants who have a partial response (PR) or better response according to the International Myeloma Working Group (IMWG) response criteria will be reported.
Up to 3 years and 5 months
Percentage of Participants with Very Good Partial Response (VGPR) or Better
Time Frame: Up to 3 years and 5 months
The percentage of participants who achieve a VGPR or better response according to the IMWG response criteria will be reported.
Up to 3 years and 5 months
Percentage of Participants with Complete Response (CR) or Stringent Complete Response (sCR)
Time Frame: Up to 3 years and 5 months
The percentage of participants with best overall response of CR or sCR will be reported according to IMWG criteria.
Up to 3 years and 5 months
Duration of Response (DOR)
Time Frame: Up to 3 years and 5 months
DOR is defined as the time from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease (PD) (defined in the IMWG response criteria) or death due to any cause, whichever occur first.
Up to 3 years and 5 months
Time to Response (TTR)
Time Frame: Upto 3 years and 5 months
TTR is defined as the time between date of the first study treatment and the first efficacy evaluation that the participant met all criteria for PR or better.
Upto 3 years and 5 months
Progression Free Survival (PFS)
Time Frame: Up to 3 years and 5 months
PFS is defined as the time from the date of the first study treatment to the date of first documented disease progression (defined in the IMWG response criteria), or death due to any cause, whichever occurs first.
Up to 3 years and 5 months
Overall Survival
Time Frame: Up to 3 years and 5 months
Overall Survival is measured from the date of the first study treatment to the date of the participant's death.
Up to 3 years and 5 months
