Brief Summary

The purpose of this study is to compare the efficacy of lenalidomide and low dose dexamethasone with pembrolizumab (MK-3475) to that of lenalidomide and low dose dexamethasone without pembrolizumab in terms of progression-free survival (PFS) in participants with newly diagnosed and treatment-naïve multiple myeloma who are ineligible for autologous stem cell transplant (Auto-SCT). The study's primary hypothesis is that pembrolizumab in dexamethasone prolongs progression free survival (PFS) as assessed by Clinical Adjudication Committee (CAC) blinded central review using International Myeloma Working Group (IMWG) response criteria compared to treatment combination with lenalidomide and low-dose with lenalidomide and low-dose dexamethasone (standard of care, SOC) alone.

Outcome Measures

Primary Outcomes (1)

• Progression Free Survival (PFS) Evaluated According to the International Myeloma Working Group (IMWG) Response Criteria 2011 by Clinical Adjudication Committee (CAC) Blinded Central Review

  PFS was defined as the time from randomization to the first documented disease progression (events of new bone lesions, soft tissue plasmacytomas or an increase in existing lesions, or death due to any cause). The median PFS was calculated from the product-limit (Kaplan-Meier) method for censored data. Due to the small number of events, the tail of the estimated survival distribution was close to the median for both arms. The higher variability of the tail estimates resulted in observing the median estimate in the experimental arm but not in the standard of care arm even when number of events in 2 arms were similar. The database cutoff date was July 9, 2018.

  Up to approximately 30 months

Secondary Outcomes (7)

• Overall Survival (OS)

  Up to approximately 55 months

• Overall Response Rate (ORR) Evaluated According to the IMWG Response Criteria by CAC Blinded Central Review

  Up to approximately 30 months

• Duration of Response (DOR) Evaluated According to IMWG Response Criteria by CAC Blinded Central Review

  Up to approximately 30 months

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

  Up to approximately 30 months

• Second Progression Free Survival (PFS2)

  Up to approximately 55 months

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Confirmed diagnosis of active multiple myeloma and measurable disease.
• Ineligible to receive treatment with auto-SCT due to age (≥65 years old) or any significant coexisting medical condition (cardiac, renal, pulmonary or hepatic dysfunction), likely to have a negative impact on tolerability of auto-SCT. Participants \<65 years of age who refuse auto-SCT are not eligible for this study.
• Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
• Female participants of childbearing potential must have 2 negative urine pregnancy tests (with a sensitivity of at least 25 Milli-international units/milliliter) within 10 to 14 days and within 24 hours prior to receiving study medication.
• Female participants of childbearing potential must agree to use adequate contraception 28 days prior to study start, continuing throughout the study, and for up to 28 days after the last dose of lenalidomide (or 120 days after the last dose of pembrolizumab).
• Male participants of childbearing potential must agree to use adequate contraception from the first dose of study medication, continuing throughout the study, and for up to 28 days after the last dose of lenalidomide (or 120 days after the last dose of pembrolizumab).

You may not qualify if:

• Has undergone prior allogeneic hematopoietic stem cell transplantation within the last 5 years.
• Has peripheral neuropathy ≥ Grade 2.
• Has a known additional malignancy that is progressing or requires active treatment within the last 5 years (except for basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy).
• Has history of non-infectious pneumonitis that required steroids or current pneumonitis
• Has received prior therapy with an anti-programmed cell death 1 receptor (anti-PD-1), anti-programmed death-ligand 1 (anti-PD-L1), anti-PD-L2, anti-CD137, or anti-cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways).
• Has a known Human Immunodeficiency Virus (HIV), or a known, active Hepatitis B (HBV), or a known, active Hepatitis C (HCV) infection.
• Is unable or unwilling to undergo thromboembolic prophylaxis including, as clinically indicated, aspirin, Coumadin (warfarin) or low-molecular weight heparin.
• Has lactose intolerance.
• Has an invasive fungal infection.
