March 21, 2019 updated by: Merck Sharp & Dohme LLC

A Phase 2 Study of Pembrolizumab in Combination With Daratumumab (Anti CD38) in Participants With Relapsed Refractory Multiple Myeloma (rrMM)

The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) in combination with daratumumab in participants with relapsed refractory multiple myeloma (rrMM). The primary outcome measure for this study is the assessment of Objective Response Rate (ORR) in participants with rrMM.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study treatment will continue until the participant has completed 35 infusions (approximately 2 years) of pembrolizumab treatment. All participants who stop study treatment with stable disease (SD) or better may be eligible for up to an additional ~1 year of study treatment if they progress after stopping study treatment from the initial treatment phase.

Study Type

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.

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
Objective Response Rate (ORR)
Time Frame: Up to approximately 2 years
ORR is defined as the percentage of participants who experience a partial response (PR; ≥50% reduction of serum myeloma (M)-protein plus reduction in 24-hour urinary M-protein by ≥90% or to <200 mg per 24 hours) or better per International Myeloma Working Group (IMWG) 2016, based on investigator assessment.
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 percentage of participants who experience stable disease (SD; not meeting criteria for complete response, very good partial response, partial response, minimal response or progressive disease) or better prior to any evidence of progression, per IMWG 2016 based on investigator assessment.
Up to approximately 2 years
Duration of Response (DOR)
Time Frame: Up to approximately 2 years
DOR is defined as the time from first documented evidence of at least a PR (≥50% reduction of serum M-protein plus reduction in 24-hour urinary M-protein by ≥90% or to <200 mg per 24 hours) until disease progression or death, per IMWG 2016, based on investigator assessment.
Up to approximately 2 years
Adverse Events (AEs)
Time Frame: Up to approximately 27 months
An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants experiencing one or more AEs will be assessed.
Up to approximately 27 months
Study Treatment Discontinuations Due to AEs
Time Frame: Up to approximately 2 years
The number of participants discontinuing study treatment due to AEs will be assessed.
Up to approximately 2 years
