About this study

Official title: A Phase III Study of Pomalidomide and Low Dose Dexamethasone With or Without Pembrolizumab (MK3475) in Refractory or Relapsed and Refractory Multiple Myeloma (rrMM) (KEYNOTE 183)

The purpose of this study is to compare the efficacy of pomalidomide and low dose dexamethasone with pembrolizumab (MK-3475) to that of pomalidomide and low dose dexamethasone without pembrolizumab in terms of Progression-Free Survival (PFS) in participants with refractory or relapsed and refractory multiple myeloma (rrMM) who have undergone at least 2 lines of prior treatment. The study's 2 primary hypotheses are: 1. Pembrolizumab in combination with pomalidomide and low dose dexamethasone prolongs PFS as assessed by Clinical Adjudication Committee (CAC) blinded central review using International Myeloma Working Group Criteria for Response Assessment in Multiple Myeloma (IMWG) criteria compared to treatment with pomalidomide and low dose dexamethasone standard of care (SOC) alone. 2. Pembrolizumab in combination with pomalidomide and low dose dexamethasone prolongs OS compared to treatment with pomalidomide and low dose dexamethasone (SOC) alone.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression Free Survival (PFS) Assessed by Clinical Adjudication Committee (CAC) Blinded Central Review According to the International Myeloma Working Group (IMWG) Response Criteria

    Progression free survival was defined as the time from randomization to the first documented disease progression, or death due to any cause, whichever occurred first. PFS was assessed by CAC blinded central review according to the IMWG criteria based on the development of new bone lesions or soft tissue plasmacytomas or on a definite increase in the size of existing bone lesions or soft tissue plasmacytomas. Median PFS was calculated from the product-limit (Kaplan-Meier) method for censored data. The database cutoff date was July 9, 2018.

    Measured: Up to approximately 30 months

  2. Overall Survival (OS)

    Overall survival is defined as the time from randomization to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. Median overall survival was calculated from the product-limit (Kaplan-Meier) method for censored data. The database cutoff date was August 3, 2020.

    Measured: Up to approximately 54 months

Secondary outcomes (5)
  1. Overall Response Rate (ORR) Evaluated According to the IMWG Response Criteria by CAC Blinded Central Review

    ORR was defined as the percentage of the participants in the analysis population who achieved at least a partial response (stringent complete response [sCR]+complete response [CR]+very good partial response [VGPR]+partial response [PR]) according to the IMWG. CR = negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND <5% plasmacytomas in the bone marrow; sCR=stringent complete response, CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence; VGPR = serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component <100 mg/24 hr; PR = ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to <200 mg/24 hours. The database cutoff date was July 9, 2018.

    Measured: Up to approximately 30 months

  2. Participants Experiencing One or More Adverse Events (AEs)

    An adverse event (AE) was defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it was considered related to the medical treatment or procedure, that occurred during the course of the study. Database cutoff was August 3, 2020.

    Measured: Up to approximately 54 months

  3. Participants Discontinuing Study Investigational Product Due to an AE

    An adverse event was defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it was considered related to the medical treatment or procedure, that occurred during the course of the study. Database cutoff was August 3, 2020.

    Measured: Up to approximately 54 months

  4. Disease Control Rate (DCR) Evaluated According to the IMWG Response Criteria by CAC Blinded Central Review

    Disease control rate was the percentage of participants who achieved confirmed sCR, CR, VGPR, PR, minimal response (MR) or have demonstrated stable disease (SD) for at least 12 weeks prior to any evidence of progression. PD was development of or an increase in the size of bone lesions or soft tissue plasmacytomas. CR = negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND <5% plasmacytomas in the bone marrow; sCR=stringent complete response, CR as above PLUS normal serum FLC assay ratio and absence of clonal cells in bone marrow by immunohistochemistry/fluorescence; VGPR = serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component <100 mg/24 hr; PR = ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to <200 mg/24 hours. The data cutoff date was July 9, 2018.

    Measured: Up to approximately 30 months

  5. Second Progression Free Survival (PFS2)

    PFS2 was defined as the time from randomization to subsequent disease progression after initiation of new anti-cancer therapy, or death from any cause, whichever occurred first, by investigator assessment. As a result of a full clinical hold by FDA that led to discontinuation of study enrollment, no data was collected for analysis of PFS2.

    Measured: Up to approximately 30 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pembrolizumab, Pomalidomide and Dexamethasone in people with Multiple Myeloma, run by Merck Sharp & Dohme LLC.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 8 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Aug 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression Free Survival (PFS) Assessed by Clinical Adjudication Committee (CAC) Blinded Central Review According to the International Myeloma Working Group (IMWG) Response Criteria (time frame: Up to approximately 30 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02576977, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2021.
