A Phase I Multi-Cohort Trial of Pembrolizumab (MK-3475) in Combination With Backbone Treatments for Subjects With Multiple Myeloma.

This is a study of pembrolizumab (MK-3475) in combination with lenalidomide and low-dose
dexamethasone in participants with refractory or relapsed and refractory Multiple Myeloma
(rrMM), and in combination with carfilzomib and low-dose dexamethasone in participants with
relapsed or refractory Multiple Myeloma (rMM).

This study is being done to find the maximum tolerated dose (MTD)/maximum administered dose
(MAD) and recommended Phase 2 dose (RP2D), and to evaluate the safety and tolerability of
pembrolizumab when given in combination with standard of care (SOC) treatments in
participants with rrMM or rMM. Preliminary efficacy data will also be assessed. The primary
study hypothesis is that these combinations are sufficiently well tolerated to permit
further clinical investigation.


Inclusion Criteria:

All Participants:

- Confirmed diagnosis of multiple myeloma (MM)

- Measurable disease

- Archival or newly obtained bone marrow material available. In addition, for
participants in the United States (US) and Canada, able to provide newly obtained
bone marrow aspirate for biomarker analysis.

- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

- Adequate organ function

- Female participants of childbearing potential must be willing to use 2 methods of
birth control or be surgically sterile, or abstain from heterosexual activity for the
course of the study through 120 days after the last dose of study treatment

- Male participants must agree to use a latex condom during sexual contact with females
of childbearing potential even if they have had a successful vasectomy starting with
the first dose of study treatment through 120 days after the last dose of study
treatment

- Able to swallow capsules and able to take or tolerate oral medications on a
continuous basis

Dose Determination Arm, Dose Confirmation Arm and Cohort 1 Participants:

- Failed at least 2 lines of prior therapy (e.g. bortezomib or carfilzomib and either
thalidomide, pomalidomide, or lenalidomide)

- Prior anti-MM treatments must have included an immunomodulatory (IMiD) treatment
(lenalidomide, pomalidomide or thalidomide) AND proteasome inhibitor (bortezomib or
carfilzomib) alone or in combination and participant must have failed therapy with an
IMiD OR proteasome inhibitor

- Must agree to follow the regional requirements for lenalidomide counseling, pregnancy
testing, and birth control; willing and able to comply with the regional requirements
(for example, periodic pregnancy tests and safety labs)

Cohort 2 Participants:

- MM with relapsing or refractory disease at study entry

- Received prior treatment with 1 to 3 lines for MM

- Achieved a partial response to at least one prior regimen (defined as ≥50% decrease
in tumor burden)

- Left ventricular ejection fraction of at least 40%

Exclusion Criteria:

All Participants:

- Currently participating in and receiving study therapy or has participated in a study
of an investigational agent or using an investigational device within 4 weeks of the
first dose of study treatment

leukemia; polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and
skin changes (POEMS) syndrome or Waldenström's macroglobulinemia

has not recovered (i.e. ≤ Grade 1 or at baseline) from a baseline AE or a Grade 1 AE
associated with agents administered more than 4 weeks earlier

- Prior anti-MM therapy (including dexamethasone), targeted small molecule therapy, or
radiation therapy within 2 weeks prior to study Day 1 or not recovered from AEs due
to a previously administered agent

last 5 years

- Clinically active central nervous system (CNS) involvement

- Active autoimmune disease or a documented history of autoimmune disease, or a
syndrome that requires systemic steroids or immunosuppressive agents

- Has a history of (non-infectious) pneumonitis that required steroids or current
pneumonitis

- Active infection requiring intravenous systemic therapy

- Known psychiatric or substance abuse disorders that would interfere with cooperation
with the requirements of the study

- Pregnant or breastfeeding, or expecting to conceive or father children within the
projected duration of the study, starting with the pre-screening or screening visit
through 120 days after the last dose of study treatment

- Prior therapy with an anti-programmed cell death (PD)-1, anti-PD ligand 1
(anti-PD-L1), anti-PD-L2, anti-CD137 antibody, or anti-Cytotoxic
T-lymphocyte-associated antigen-4 (CTLA-4) agent
