5.1. Inclusion
Criteria (Criterion 2)
Deleted ‘Multiple myeloma diagnosis according
to the International Myeloma Working Group
(IMWG) diagnostic criteria’. 
This study evaluates daratumumab
retreatment and therefore does not
apply the IMWG criteria.
5.2. Exclusion
Criteria (Criterion
18)
The exclusion criterion has been modified to exclude
only those participants who have tested seropositive
for HIV with 1 or more of the following:
 
Not receiving highly active antiretroviral
therapy (ART)
 
Had a change in ART within 6 months of the
start of screening
 
Receiving ART that may interfere with study
treatment (consult Sponsor for review of
medication prior to enrollment)
 
CD4 count <350 at screening
 
Acquired immunodeficiency syndrome (AIDS)-
defining opportunistic infection within 6 months
of start of screening
 
Not agreeing to start ART and be on ART >4
weeks plus having HIV viral load <400
copies/mL at end of 4-week period (to ensure
ART is tolerated and HIV controlled) 
To include participants who are
seropositive for HIV and meet
specified criteria for managing the
disease.
6.1.1.4. Dose
Modification
Text was revised. Text in strikethrough has been
deleted, text in bold has been added.
The study intervention must be held if any of the
following criteria are met, to allow for recovery from
toxicity, regardless of relationship to study
intervention
If any of the following criteria are met and the
toxicity is more than expected for the backbone
therapy (carfilzomib, dexamethasone), or
underlying multiple myeloma, the daratumumab
injection must be held to allow for recovery from
toxicity as noted below. If attribution is unclear,
then daratumumab should be held until recovery
To clarify that daratumumab should
be held only if events are not
attributed to carfilzomib or
dexamethasone (Kd).

PROTOCOL SUMMARY
1.1. 
Synopsis
A Phase 2 Study of Daratumumab Subcutaneous (Dara-SC) Administration in Combination with
Carfilzomib and Dexamethasone (DKd) Compared with Carfilzomib and Dexamethasone (Kd) in
Participants with Multiple Myeloma who have been Previously Treated with Daratumumab to Evaluate
Daratumumab Retreatment
OBJECTIVES AND ENDPOINTS
Objectives
Primary Objective
The primary objective is to compare the efficacy (rate of very good partial response [VGPR] or better as
best response as defined by the International Myeloma Working Group [IMWG] criteria) of Dara-SC in
combination with Kd with the efficacy of Kd in participants with relapsed refractory multiple myeloma
who were previously exposed to daratumumab to evaluate daratumumab retreatment.
Secondary Objectives
The secondary objectives are:
To further characterize the efficacy (progression-free survival [PFS], overall survival [OS], overall
response rate [ORR], rate of complete response [CR]/stringent complete response [sCR]) of Dara-SC in
combination with Kd
 
To evaluate the minimal residual disease (MRD) negativity rate and durability of MRD
negativity status
 
To characterize the safety of Dara-SC in combination with Kd
 
To determine time to next treatment
 
To evaluate the pharmacokinetics (PK) of Dara-SC
 
To determine the immunogenicity  of daratumumab and recombinant human hyaluronidase
PH20 (rHuPH20)
Endpoints
Primary Endpoint
The primary endpoint of this study is the rate of VGPR or better as defined by the IMWG criteria.
Secondary Endpoints
The secondary endpoints are:
 
ORR (rate of partial response [PR], VGPR, CR, sCR)
 
Rate of CR/sCR
 
PFS
 
OS
 
MRD negativity rate
 
Time to next treatment

Hypothesis
Daratumumab SC in combination with Kd will have a higher VGPR or better rate than Kd in participants
who have previously received 1 to 3 prior lines of therapy including a line containing daratumumab.
OVERALL DESIGN
This is a Phase 2, open-label, randomized, multicenter study to determine the efficacy of DKd in adult
participants with relapsed refractory multiple myeloma who had 1 to 3 prior line(s) of treatment including
a line containing daratumumab to evaluate daratumumab retreatment. Participants must have completed
daratumumab at least 3 months prior to randomization. The study will be conducted in 3 phases:
Screening, Treatment, and Follow-Up. During the Treatment Phase, participants will be randomized to
receive Kd or DKd. Participants will be stratified by prior proteasome inhibitor exposure and
daratumumab-free interval (3-6 months, >6 months). Participants in both arms will receive study
intervention until confirmed progressive disease (PD), death, intolerable toxicity, start of a new treatment
for multiple myeloma, withdrawal of consent, or end of the study, whichever occurs first. Follow up of
participants for disease progression and survival will continue during the Follow-up Phase.
NUMBER OF PARTICIPANTS
Approximately 230 participants will be randomized 1:1 in 2 treatment arms.
INTERVENTION GROUPS AND DURATION
Participants will be treated with Kd alone (Arm A) or Dara SC in combination with Kd (Arm B) in
28-day cycles.
EFFICACY EVALUATIONS
Assessment of tumor response and disease progression will be conducted in accordance with the IMWG
response criteria. Efficacy evaluations will include measurements of tumor burden/residual disease,
myeloma proteins, bone marrow examinations, extramedullary plasmacytomas, and serum calcium
corrected for albumin.
PHARMACOKINETIC AND IMMUNOGENICITY EVALUATIONS
Samples will be collected from all participants to assess both the serum concentration (pharmacokinetics)
of daratumumab and the presence and generation of anti-daratumumab antibodies (ADAs;
immunogenicity) according to the Schedule of Activities. Samples will also be collected from all
participants in Arm B to evaluate the immunogenicity of rHuPH20 according to the Schedule of
Activities.
BIOMARKER EVALUATIONS
Bone marrow samples will be collected from all participants in both arms to evaluate MRD and high-risk
cytogenetics anomalies as outlined in the Schedule of Activities. Whole blood and plasma samples will be
collected from participants as specified in the Schedule of Activities for processing to plasma and
peripheral blood mononuclear cells and may be used to evaluate the mechanism of action of
daratumumab in combination with Kd.

SAFETY EVALUATIONS
Safety evaluations will include a review of adverse events, clinical laboratory test results, vital sign
measurements, electrocardiograms (or multiple-gated acquisition [MUGA] scans), physical examination
findings, and assessment of Eastern Cooperative Oncology Group (ECOG) performance status grade.
STATISTICAL METHODS
The primary endpoint of this study is the rate of VGPR or better as defined by the IMWG criteria. The
sample size is based on the assumption that the VGPR or better rate is 60% for DKd and 45% for Kd. In
the current study, 230 participants (assigned 1:1) are needed in order to detect an absolute 15% increase in
VGPR or better rate with 70% power using a 2-sided chi-squared test at the 10% significance level. The
rate of VGPR or better will be compared between the 2 treatment arms using the stratified
Cochran-Mantel-Haenszel test. The primary analysis will be conducted approximately 6 months after the
last participant receives the initial dose of study intervention. An interim futility analysis will occur when
40% of participants are enrolled and treated for 6 months.

INTRODUCTION
For the most comprehensive nonclinical and clinical information regarding daratumumab, refer
to the latest version of the Investigator's Brochure (IB) for daratumumab. The term “study
intervention” used throughout the protocol, refers to daratumumab subcutaneous (Dara-SC)
administration in combination with carfilzomib and dexamethasone (DKd) or carfilzomib and
dexamethasone (Kd). The term "sponsor" used throughout this document refers to the entities
listed in the Contact Information page(s), which will be provided as a separate document.
2.1. 
Background
2.1.1. 
Multiple Myeloma
For relapsed or refractory multiple myeloma, the treatment is determined on an individual basis
where the patient’s age, prior therapy, bone marrow function, co-morbidities, patient preference
and time to relapse are considered. Common standard of care regimens use either a proteasome
inhibitor (PI) or an immunomodulatory agent (IMiD) in combination with dexamethasone with
or without a monoclonal antibody (mAb) such as daratumumab. With each successive relapse,
the depth and duration of response typically decreases. After relapse from PIs or IMiDs, patients
are often retreated with drugs that have the same mechanism of action to which they have been
sensitive. Ultimately, the disease becomes refractory and all effective treatment options are
exhausted and patients who are heavily pretreated or refractory to both a PI and an IMiD have a
dismal prognosis, are difficult to get back into a durable remission, and have a median overall
survival (OS) of only 8 to 9months.10,23,24 For patients who are refractory to at least 3 of the
common PIs (bortezomib or carfilzomib) and IMiDs (lenalidomide or pomalidomide), the
median OS decreases to only 5 months.23 As such, multiple myeloma remains incurable.
2.1.2. 
Daratumumab
Daratumumab is a human IgG1ĸ mAb that binds with high affinity to a unique epitope on cluster
of differentiation 38 (CD38). It is a targeted immunotherapy that attacks tumor cells that
overexpress CD38, a transmembrane glycoprotein, in a variety of hematological malignancies
including multiple myeloma. Daratumumab induces lysis of CD38-expressing tumor cells,
including multiple myeloma tumor cells that were freshly isolated from patients, by a number of
mechanisms, including complement-dependent cytotoxicity, antibody-dependent cell-mediated
cytotoxicity, and antibody-dependent cellular phagocytosis, through activation of complement
proteins, natural killer (NK) cells, and macrophages, respectively.6,20
2.1.3. 
Daratumumab IV
In the European Union (EU), daratumumab is approved for the following indications:
 
As monotherapy for the treatment of adult patients with relapsed and refractory multiple
myeloma, whose prior therapy included a PI and an IMiD and who have demonstrated
disease progression on the last therapy.

2.1.4. 
Daratumumab SC
A new formulation of daratumumab for subcutaneous (SC) administration has been developed to
avoid the long infusion time that frequently requires hospitalization with intravenous (IV)
administration of daratumumab and to lessen the rate and severity of infusion-related reactions
(IRRs) observed with IV daratumumab. A recombinant human hyaluronidase PH20 (rHuPH20)
was used to facilitate the SC administration of daratumumab to decrease the volume required for
SC administration.
This SC formulation of daratumumab has been evaluated in Study MMY1004, an open-label,
multicenter, dose escalation Phase 1b study. Study MMY1004 was designed to assess the safety,
pharmacokinetics (PK), and efficacy of Dara-SC plus rHuPH20 in participants with relapsed or
refractory multiple myeloma. The fixed SC dose of 1800 mg was selected from Part 1 of the
study based on cumulative review of PK and safety data and confirmed with Dara-SC in Part 2.
Similar or greater maximum trough concentrations (Ctrough) were observed following

administration of 1800 mg Dara-SC compared to 16 mg/kg daratumumab IV (Dara-IV). After a
median treatment duration of 5.6 months, 25 participants received at least 1 dose of 1800 mg
Dara-SC in Study MMY1004.22 The IRR rate was 16%; events were mostly Grade 1 or 2 and
included chills, dyspnea, sneezing and allergic rhinitis, and two Grade 3 events of hypertension.
None of the IRRs led to treatment discontinuation. Injection-site reactions (ISRs) included
erythema in 24% of participants, and induration at injection site was experienced by 1 participant
(4%). The overall response rate (ORR) was 52%, with 28% very good partial responses
(VGPRs). Median time to response was 1 month. Median progression free survival (PFS) has not
been reached.
The efficacy and AE profile of Dara-SC is consistent with that of Dara-IV with a lower rate of
IRRs (12% with Dara-SC versus 48% in Dara-IV monotherapy and combination studies), which
mainly occur with the first injection. Based on these clinical data and supported by the PK
profile of Dara-SC, the safety and efficacy profile of Dara-SC appears similar to the profile
Dara-IV. The profile of Dara-SC may be better with regard to IRR. The SC formulation is
currently being tested in Study MMY3012, a Phase 3 study of Dara-IV versus Dara-SC in
participants with relapsed or refractory multiple myeloma.
2.2. 
Study Rationale
Daratumumab responders who relapse have been reported to become re-sensitized (responded
again) following an adequate treatment break or by switching to a different
daratumumab-containing combination regimen.1,2 Two patients with triple refractory (IMiDs,
PIs, and cytostatics) multiple myeloma were retreated with Dara-IV with a partial response after
relapsing from a prior line of therapy containing daratumumab.2 A retrospective study of
41 patients at Emory University Hospital, using daratumumab in combination with
pomalidomide and dexamethasone, showed that patients with prior daratumumab exposure may
be effectively retreated with daratumumab in a re-intensified dosing schedule.1 These data
suggest that retreatment with daratumumab may result in a multiple myeloma disease response.
However, the clinical benefit of daratumumab retreatment has not been systematically evaluated.
As daratumumab moves into frontline treatment, evidence to support retreatment with
daratumumab among patients with disease progression is needed.
The dosing schedule of carfilzomib in combination with dexamethasone (Kd) to be used in this
study has been approved by the Food and Drug Administration (FDA) for patients with relapsed
or refractory multiple myeloma who had 1 to 3 prior line(s) of therapy. The Phase 3
ENDEAVOR study, in which 929 patients were enrolled compared the efficacy of Kd with
bortezomib-dexamethasone (Vd) in patients who progressed on 1 to 3 prior regimen(s).7
Participants (n 464) received twice weekly carfilzomib at 20 mg/m2 on Days 1-2 of Cycle 1, and
subsequent doses of 56 mg/m2 thereafter as a 30 minute IV infusion. All patients received 20 mg
dexamethasone (IV or oral [PO]) on Days 1, 2, 8, 9, 15, 16, 22, and 23 of every cycle. The Kd
group had an ORR of 77% compared with 63% in the Vd arm; median PFS of 18.7 months
compared with 9.4 months in the Vd arm; and median OS of 47.6 months compared with
40 months in the Vd arm. On-study deaths due to adverse events (AEs) occurred in 4% of

participants. Forty eight percent (48%) of participants had serious adverse events (SAEs). The
most frequent Grade 3 or higher AEs were anemia (14%), hypertension (9%), thrombocytopenia
(8%) and pneumonia (7%).
To evaluate a more convenient carfilzomib dosing schedule, the Phase 3 ARROW study
compared once weekly (70 mg/m2) with twice weekly (27 mg/m2) carfilzomib dosing in
478 participants with relapsed or refractory multiple myeloma.15 The once weekly group
received carfilzomib (30 min IV infusion) on Days 1, 8, and 15 of all cycles (20 mg/m² Day 1
during Cycle 1; 70 mg/m² thereafter). The twice weekly group received carfilzomib (10-min IV
infusion) on Days 1, 2, 8, 9, 15, and 16 (20 mg/m² Days 1 and 2 during Cycle 1; 27 mg/m²
thereafter). All patients received dexamethasone (40 mg on Days 1, 8, 15 [all cycles] and
22 [Cycles 1 9 only]). The once weekly group had a higher median PFS compared to the twice
weekly group, 11 months compared with 8 months, respectively. The ORR in the once-weekly
group was 62.9% (95% confidence interval [CI], 56.5-69.0) compared with 40.8% (95% CI,
35.5-47.3) in the twice-weekly group (P <.0001); 7% of patients and 2% of patients,
respectively, achieved a complete response (CR) or stringent complete response (sCR). The
incidence of Grade 3 AEs was higher in the once weekly group (68%) compared with the twice
weekly group (62%). The most common events in the once weekly group were anemia (18%),
pneumonia (10%), and thrombocytopenia (7%). The once weekly group had 2% treatment-
related deaths and 58 total deaths, and the twice weekly group had 1% treatment-related deaths
and 68 total deaths. This study resulted in the recent FDA approval of the carfilzomib once
weekly (70 mg/m2) dose.
Study MMY1001 is a Phase 1b study evaluating the safety and efficacy of Dara-IV with Kd.
Participants received once weekly carfilzomib (30 min IV infusion) on Days 1, 8, and 15 of all
cycles (20 mg/m² Day 1 during Cycle 1; 70 mg/m² thereafter). Participants with 1-4 prior line(s)
of therapy (n 85) had a VGPR or better rate of 68% and an 81% ORR. In a subgroup analysis of
participants with 1-2 prior line(s) of therapy (n 60), the VGPR or better rate was 73% and the
ORR was 87%. Grade 3 or 4 treatment-emergent adverse events (TEAEs) were reported in 73%
of participants receiving DKd. The most frequently reported Grade 3 or 4 TEAEs (≥10%) in the
DKd cohort were thrombocytopenia (31%), anemia (21%), lymphopenia (22%), neutropenia
(21%), hypertension (14%), and asthenia (12%). For further details and the most up-to-date
information about Study MMY1001, refer to the most current IB.
Given the growing use of lenalidomide in newly diagnosed multiple myeloma (especially in the
maintenance setting), as well as safety and efficacy data of using carfilzomib in patients with
relapsed and refractory multiple myeloma, evaluation of the safety and efficacy of the addition of
Dara-SC to this regimen is proposed.
2.3. 
Benefit/Risk Assessment
The combination of Kd with Dara-SC is hypothesized to have a positive benefit-risk profile
when used for the treatment of patients with relapsed/refractory multiple myeloma who were
previously exposed to daratumumab. This hypothesis is based on the following:

Daratumumab responders who relapse may respond following a treatment break or by switching
to a new daratumumab-containing combination regimen, as detailed in Section 2.2.
The Kd regimen to be used in this study has been approved for patients with relapsed or
refractory multiple myeloma who had 1 to 3 prior line(s) of therapy (see Section 2.1.1).
The addition of daratumumab to the Kd regimen may improve initial disease control and long-
term outcomes, based on data from an ongoing Phase 1b study (Study MMY1001) of the safety
and efficacy of Dara-IV with Kd (see Section 2.2).
Given the potential advantages of SC administration, Dara-SC will be used in this study. As
presented in Section 2.1.4  and the current daratumumab IB, the safety and tolerability of
Dara-SC has been demonstrated. Previous exposure-response analyses have demonstrated a
strong correlation between ORR and the maximum daratumumab Ctrough. Analysis of the
preliminary PK data indicated the 1800 mg Dara-SC dose achieved maximum Ctrough  values
comparable with, or higher than, those observed for Dara-IV 16 mg/kg as detailed in Section 4.2.
Considering the above, there is a strong rationale for evaluating Dara-SC in combination with Kd
for the treatment of relapsed refractory multiple myeloma patients previously exposed to
daratumumab. More detailed information about the known and expected benefits and risks of
daratumumab are provided in the IB.

OBJECTIVES AND ENDPOINTS
OBJECTIVES
Primary Objective
The primary objective is to compare the efficacy (rate of VGPR or better as best response as

myeloma who were previously exposed to daratumumab to evaluate daratumumab retreatment.
Secondary Objectives
The secondary objectives are:
 To further characterize the efficacy (PFS, OS, ORR, rate of CR/sCR) of Dara-SC in
combination with Kd
 To evaluate the minimal residual disease (MRD) negativity rate and durability of MRD
negativity status
 To characterize the safety of Dara-SC in combination with Kd

HYPOTHESIS
Daratumumab SC in combination with Kd will have a higher VGPR or better rate than Kd in
participants who have previously received 1 to 3 prior lines of therapy including a line
containing daratumumab.
4. 
STUDY DESIGN
4.1. 
Overall Design
This is a Phase 2, open-label, randomized, multicenter study to determine the efficacy of DKd in
adult participants with relapsed refractory multiple myeloma who had 1 to 3 prior line(s) of
treatment including a line containing daratumumab to evaluate daratumumab retreatment.
Participants must have completed daratumumab at least 3 months prior to randomization. A
target of 230 participants will be randomized in 2 treatment arms of 115 each.  A diagram of the
study design is provided in Section 1.2 Schema.
The study will be conducted in 3 phases: Screening, Treatment, and Follow-Up. Screening
begins at the time the participant provides written consent for study participation. During the
Screening Phase, participants will be screened for study eligibility within 28 days prior to study
randomization. All eligibility criteria must be met prior to starting study intervention.

Approved, Date: 3 June 2021
During the Treatment Phase, participants will be stratified by prior PI exposure and
daratumumab-free interval (3-6 months, >6 months) and then assigned randomly to receive Kd
or DKd. Participants in both arms will receive study intervention until confirmed progressive
disease (PD), death, intolerable toxicity, start of a new treatment for multiple myeloma,
withdrawal of consent, or end of the study, whichever occurs first. Participants should start study
intervention within 3 days after randomization. Participants will be closely monitored for AEs,
laboratory abnormalities, and clinical response. Clinical evaluations and laboratory studies may
be repeated more frequently, if clinically indicated. If disease progression is confirmed, then the
participant will discontinue study intervention, complete the End-of-Treatment Visit, and enter
the Follow-up Phase.
Follow-up will continue until the end of study, no later than 2 years after the last participant has
received their initial dose of study intervention or when the sponsor decides to stop the study.
The sponsor will ensure that participants benefiting from treatment with Dara-SC or carfilzomib
continue to receive treatment after the end of the study.
All study evaluations will be conducted according to the Schedule of Activities (Table 1 to
Table 3). Myeloma protein measurements in serum and urine for disease evaluations will be
performed by a central laboratory (unless otherwise specified). Bone marrow testing will be
performed by both local and central laboratories. This study will use the IMWG consensus
recommendations for multiple myeloma treatment response criteria9,21 presented in Table 10.
Response will be determined using a validated computer algorithm.
Safety evaluations will include a review of AEs, laboratory test results, vital sign measurements,
physical examination findings, and assessment of Eastern Cooperative Oncology Group (ECOG)
performance status grade. Follow up of participants for disease progression and survival will
continue during the Follow-up Phase.
An interim futility analysis will be conducted after 40% of participants are enrolled and treated
for at least 6 months (approximately 1 year after first participant randomized). The primary
analysis will be conducted approximately 6 months after the last participant receives the initial
dose of study intervention. At this time, the clinical study report (CSR) will be written, or the
CSR will be written at the time of interim futility analysis if the results lead to stopping the
study. A final analysis will occur at study completion/end of the study to update PFS2, OS,
second primary malignancy, and safety. Study completion/end of the study will be no later than
2 years after the last participant has received the initial dose of study intervention.
4.2. 
Scientific Rationale for Study Design
This study will test the hypothesis that daratumumab retreatment in combination with Kd,
following at least a 3-month daratumumab-free interval, would result in an improved clinical
benefit over Kd alone, in relapsed and refractory multiple myeloma. The study population
includes patients who have had 1 to 3 prior line(s) of therapy and have demonstrated at least a
partial response for 4 months to daratumumab. Given the setting of retreatment with

JNJ-54767414  (daratumumab)
Clinical Protocol 54767414MMY2065 Amendment 2

32
Approved, Date: 3 June 2021
daratumumab, a clinically meaningful primary endpoint would be VGPR rate or better as it
represents a 90% or more reduction in detectable abnormal paraproteins.
The patients will be stratified based on daratumumab-free interval and prior PI exposure. It is
unknown whether the degree to which CD38 re-expression or the additional immune modulating
responses secondary to daratumumab may correlate to retreatment clinical benefit. The inclusion
of this stratification criterion is to guard against potential influence on patient response. Post hoc
analyses will examine the need for, and optimal length of a daratumumab-free interval prior to
retreatment with daratumumab.  CD38 expression starts to slowly increase when daratumumab is
gradually cleared. By the end of a 3-month daratumumab-free interval, daratumumab remaining
levels are very low, and CD38 expression starts to increase again. It can take up to 5 months for
CD38 expression to reach its initial levels.18 However, in previous studies CD38 expression
levels did not correlate with response to daratumumab treatment either in a monotherapy or in
combination setting. Stratification by 3-6 months and >6 months serves to address this point.
CD38-expressing immune cell populations are mostly depleted immediately after first
daratumumab infusion and remain like this as long as daratumumab is present.
Daratumumab has a mean linear half-life associated with linear elimination of 18 to 23 days
following monotherapy and combination treatment.  A 3-month daratumumab-free-interval is
4 to 5 half-lives, which allows time for washout of most of the daratumumab from serum prior to
initiation of study treatment. Hence, a minimum of 3-month daratumumab-free-interval is
necessary to determine the effect, if any at all, of daratumumab in retreatment.
Blinding, Control, Study Phase/Periods, Intervention Groups
This study is not blinded. An active control will be used to determine the sensitivity of the
clinical endpoints in this study. Randomization will be used to minimize bias in the assignment
of participants to intervention groups, to increase the likelihood that known and unknown
participant attributes (eg, demographic and baseline characteristics) are evenly balanced across
intervention groups, and to enhance the validity of statistical comparisons across intervention
groups.
Rationale for Subcutaneous Daratumumab
Subcutaneous administration of daratumumab has been chosen for this study to avoid the long
infusion time that frequently requires hospitalization with Dara-IV and to lessen the rate and
severity of IRRs observed with Dara-IV.
Biomarker Collection
This study provides an opportunity to evaluate whether daratumumab retreatment results in
significant and deep responses in participants who responded to initial treatment with
daratumumab. Having as a goal to achieve deep and sustained responses, the measurement of
MRD is important as a key differentiator. Daratumumab’s mechanisms of action are a
combination of direct on-tumor as well as immunomodulatory actions. In this study, by means of
immune profiling, the aim is to identify alterations in immune cell subgroups which might result

in a secondary response to daratumumab. Being able to better understand the disease’s biology in
association with the clinical data might guide a rationale for combination therapies.
Pharmacokinetics and Immunogenicity Assessments
Data obtained from this study will provide information about the PK profile of DKd in
participants with multiple myeloma and previous daratumumab exposure.  Data will also be used
to assess the residual daratumumab serum concentration at the start of treatment in the Kd arm
following at least 3-month daratumumab-free interval. Therefore, samples will be obtained from
all participants for PK assessments. Data may also be used for a population PK analysis to
estimate additional PK parameters and provide information about the determinants of
inter-participant variability in this population.
Immunogenicity to daratumumab or rHuPH20 is possible. The prevalence and incidence of
daratumumab immunogenicity may be different in this population that has previously been
exposed to daratumumab, therefore, the presence of anti-daratumumab antibodies and
anti-rHuPH20 antibodies will be determined from samples collected from all participants.
Medical Resource Utilization Data Collection
Treatment of multiple myeloma with daratumumab SC administration in combination with Kd
versus Kd alone may result in lower utilization of:
 Duration of hospitalization (total length of stay, including duration by each hospital unit)
 Number and character of diagnostic and therapeutic tests and procedures
 Outpatient medical encounters (including physician, nurse practitioner or emergency
room visits, tests and procedures)
Therefore, comparison will be done across intervention groups.
4.2.1. 
Study-Specific Ethical Design Considerations
Potential participants will be fully informed of the risks and requirements of the study and, during
the study, participants will be given any new information that may affect their decision to continue
participation. They will be told that their consent to participate in the study is voluntary and may be
withdrawn at any time with no reason given and without penalty or loss of benefits to which they
would otherwise be entitled. Only participants who are fully able to understand the risks, benefits,
and potential AEs of the study, and provide their consent voluntarily will be enrolled.
The primary ethical concerns based on the mode of action of daratumumab are infection and
hematological disturbances. Therefore, the protocol requires the review of past medical history of
infections and hematological laboratory results prior to study intervention administration. CD38
is distributed in erythrocytes and platelets. A significant reduction of platelets was reported in an
animal study. Across daratumumab trials, thrombocytopenia was also reported. However, safety
laboratory monitoring did not show a clinically meaningful reduction of platelets. Anemia was
also reported in daratumumab trials. Free hemoglobin was mildly elevated, but other parameters

did not support hemolysis. No bleeding events were observed. Routine safety laboratory
measurement of red blood cells (RBCs) and platelets will be closely monitored in this study.
In a previous study with SC administration of daratumumab (Study MMY1004), a lower
incidence of IRRs was observed compared to the IRR rate reported from studies with IV
administration of daratumumab. However, IRRs may still occur and may develop at a later
timepoint than previously observed with IV administration due to the more gradual absorption.
Participants will therefore be observed for at least 6 hours on their first day of Dara-SC
administration. Apart from IRRs, a similar toxicity profile has been shown for SC versus IV
administration for anemia, thrombocytopenia, and other toxicities. During this study local
tolerability at the SC injection site will be closely monitored as well.
The addition of Dara-IV in combination with Kd in a subgroup analysis of Study MMY1001
demonstrated a 73% VGPR rate or better in patients with relapsed or refractory multiple
myeloma previously treated with 1 to 2 prior lines of therapy. Carfilzomib weekly in
combination with dexamethasone in patients with relapsed or refractory multiple myeloma
demonstrate VGPR or better rate of 34% in ARROW study, and 44% in CHAMPION-1 study in
patients previously treated with 1 to 3 prior lines of therapy. The safety profile of weekly Kd and
the addition of daratumumab is comparable. For further details and the most up-to-date
information about single-agent studies, please refer to the Investigator's Brochure. The efficacy
of daratumumab retreatment in combination with Kd in patients who are carfilzomib naive is
unknown. In this study, participants randomized to Arm A or Arm B will be closely monitored
for both safety and efficacy.
Blood volumes drawn are provided in Section 8. The total blood volume to be collected is
considered to be acceptable for participants with multiple myeloma participating in a clinical study
and reasonable over the timeframe of the study.
4.3. 
Justification for Dose
4.3.1. 
Rationale for Daratumumab SC Dose Regimen
Previous exposure-response analyses have demonstrated a strong correlation between ORR and
the Ctrough, of daratumumab, which occurs at the end of weekly dosing (just prior to the Cycle 3
Day 1 dose in the 16 mg/kg monotherapy schedule). These analyses have also demonstrated the
lack of relationship between daratumumab concentrations and AEs in the therapeutic dose range.
Therefore, the dose of Dara-SC selected is intended to achieve a similar or greater maximum
Ctrough compared with 16 mg/kg IV administration.
Eighteen participants were evaluable for PK analyses in Study MMY1004 Part 2. Analysis of the
preliminary PK data indicated the 1800 mg Dara-SC (co-formulated) dose achieved maximum
Ctrough  values comparable to, or higher than, those observed for Dara-IV 16 mg/kg. The
maximum Ctrough  mean value was 904.42 µg/mL for the 1800 mg Dara-SC cohort (n 18),
compared with 754.62 µg/mL for the 1800 mg daratumumab and recombinant human
hyaluronidase for SC injection: mix and deliver formulation (Dara-MD) cohorts (n 38),

617.17 µg/mL in Study GEN501 Part 2 (n 27), and 573.49µg/mL in Study MMY2002 (n 73).
The median value for maximum Ctrough  for Dara-SC (798.85 µg/mL) was similar to the value for
1800 mg Dara-MD (795.48 µg/mL) and slightly higher than the 16 mg/kg IV median values
from Studies MMY2002 (559.62 µg/mL) and GEN501 (713.85 µg/mL). The range of maximum
Ctrough  observations for the SC cohort is contained within the range observed following 16 mg/kg
IV dosing and variability was similar with a % coefficient of variation of 46 to 58% across the
SC and IV doses (Figure 2).The observed mean maximum observed concentration (Cmax) values
following the last (8th) weekly dose for the Dara-SC cohort was 1012.4 µg/mL, similar to the
mean Cmax of 914.9µg/mL observed after the Cycle 3 Day 1 (9th) dose for Dara-IV in
Study MMY2002. The observed Cmax  values from the Dara-SC cohort is within the range
observed for Dara-MD and 16 mg Dara-IV.

1800 mg SC = MMY1004 Part 2, 1800 mg co-formulant
16 mg/kg IV data are from Study MMY2002
Study MMY1004 Part 2 also showed that 1800 mg Dara-SC can be administered SC by injection
with a median of 5 minutes (ranging from 2 to 11 minutes) and it is associated with a low
incidence of IRRs, as noted above. The safety profile for the Dara-SC cohort is consistent with
previously reported safety profiles for Dara-IV administration and SC administration with
Dara-MD. There are no new safety signals with the Dara-SC administration. Therefore, based on
the available safety and PK data, the dose of 1800 mg Dara-SC is selected for study in Phase 3
studies, as well as this Phase 2 study.
The daratumumab schedule utilized for this study is the same as has been used in the DKd cohort
of Study MMY1001 with Dara-IV and as monotherapy in Studies MMY1004 and MMY3012

with Dara-SC. The dose regimen is 1800 mg Dara-SC weekly for 2 cycles, every 2 weeks for
4 cycles, and every 4 weeks thereafter (cycles are 4 weeks); this schedule is intended to quickly
achieve and maintain effective daratumumab concentrations.
4.3.2. 
Rationale for Daratumumab Fixed Dose
The body weight range in Part 1 of Study MMY1004 was 48 to 133 kg, which was similar to that
in Dara-IV studies (MMY2002 and GEN501, 38.4 to 160.2 kg). The preliminary
maximum Ctrough  data for the Dara-MD 1800 mg dose were assessed across a range of simulated
body weights and compared with the body weight based Dara-IV dosing. Across the quartiles of
weights for the simulated participants (n 1000), similar exposure was predicted for each dosing
approach (either Dara-MD  1800 mg or Dara-IV 16 mg/kg) (Figure 3). Furthermore, the
variability in the exposure for Dara-MD  1800 mg in all weight quartiles was predicted to be
similar compared with that for Dara-IV 16 mg/kg. The fixed Dara-MD 1800 mg dose results in a
median concentration that is close to the overall population median concentration, with a ratio of
approximately 1 in each weight quartile (Figure 4). Based on these simulations and observations
in the ongoing Study MMY1004, fixed dosing for SC administration is a feasible approach and
will be used in this study. Dara-IV exhibits a wide therapeutic window and there is no apparent
relationship between drug exposure in the therapeutic dose range and AEs of interest, which
further supports the feasibility of utilizing a fixed dose approach in SC administration.

4.3.3. 
Rationale for Carfilzomib Dose Selection
The carfilzomib weekly dosing was chosen based on the Phase 3 ARROW study that compared
once weekly carfilzomib (70 mg/m2) with twice weekly carfilzomib (27 mg/m2) in combination
with dexamethasone.15 The once weekly carfilzomib regimen had a 3.6 month longer PFS and a
higher proportion of participants achieving response. No additional or new toxic effects were
identified in the once weekly dosing regimen and the safety profile was consistent with the
known safety profile of carfilzomib. Hence, this study will use the carfilzomib once weekly
(70 mg/m2) dosing regimen in combination with dexamethasone to reduce the dosing and
administration burden on participants.
Participants will receive 20 mg/m2 carfilzomib as a 30-minute IV infusion on Cycle 1 Day 1. The
second dose of carfilzomib will be escalated to 70 mg/m2, as a 30-minute IV infusion on Cycle 1
Days 8 and 15.
4.4. 
End of Study Definition
The end of study is no later than 2 years after the last participant has received their initial dose of
study intervention or when the sponsor decides to stop the study. The final data from the study
site will be sent to the sponsor (or designee) after completion of the final participant assessment
at that study site, in the time frame specified in the Clinical Trial Agreement.

intrauterine device, hormonal [birth control pills, injections, hormonal patches, vaginal
rings or implants] or partner's vasectomy) and one additional effective contraceptive
method (male latex or synthetic condom, diaphragm, or cervical cap). A reduction in the
effectiveness of oral contraceptives during carfilzomib treatment cannot be excluded. In
addition, because of the increased risk of venous thromboembolic events associated
with carfilzomib, women should avoid the use of hormonal contraceptives that are
associated with a risk of thrombosis during treatment with carfilzomib. Women of
childbearing potential who are using oral contraceptives or a hormonal method of
contraception that is associated with a risk of thrombosis should switch to an alternative
method of highly effective contraception. Contraception must begin with study
treatment initiation  and continue for 3 months after discontinuing study treatment.
Reliable contraception is indicated even where there has been a history of infertility,
unless due to hysterectomy.
A woman must agree not to donate eggs (ova, oocytes) for the purposes of assisted
reproduction during the study and for a period of 3 months after receiving the last dose
of any component of the study treatment.
Male participants who are sexually active with women of childbearing potential or with
pregnant women must always use a latex or synthetic condom during the study and for
3 months after discontinuing study treatment (even after a successful vasectomy).
Male participants of reproductive potential must not donate sperm during the study or
for 3 months after the last dose of study treatment.

6.1.1. 
Daratumumab (Arm B Only)
Dara-SC will be administered by SC injection at a fixed dose of 1800 mg. The dose of Dara-SC
will remain constant throughout the study, and dose modification of Dara-SC (increase or
decrease) is not permitted. On days when more than one investigational product is administered,
the required order of administration is as follows:  dexamethasone (see Section 6.1.2),
pre-administration medications for Dara-SC  (see Sections 6.1.1.1), Dara-SC, then carfilzomib
(see Section 6.1.3). Dose delay is the primary method for managing daratumumab-related
toxicities as summarized in Section 6.1.1.4.
Doses will be administered by manual push over 3-5 minutes in the abdominal SC tissue in
left/right locations, alternating between individual doses. The volume of the SC solution for
injection will be 15 mL for the 1800 mg dose. Refer to the Investigational Product Preparation
Instructions (IPPI) for additional guidance on SC administration of Dara-SC. Participants will
receive pre-administration medications and post-administration medications as outlined in
Sections 6.1.1.1 and 6.1.1.2, respectively. All participants in Arm B will be observed for at least
6 hours after the end of the SC injection during Cycle 1 Day 1 and, if deemed necessary by the
investigator, after subsequent injections. Reasons for continued observation on subsequent
Dara-SC injections may include but are not limited to the following: participants with a higher risk
of respiratory complications (eg, participants with mild asthma or participants with COPD who
have an FEV1 <80% at screening or developed FEV1 <80% during the study without any medical
history), participants with IRR with first injection of Dara-SC, or participants with a decreased
condition on day of dosing compared to prior dosing day.
If an IRR develops, then the injection should be temporarily interrupted or slowed down (see
Section 6.1.1.3.2). In the event of a life-threatening IRR (which may include pulmonary or
cardiac events) or anaphylactic reaction, Dara-SC  should be discontinued and no additional
Dara-SC should be administered to the participant. See Section 6.1.1.3.1 for instructions on the
management of local ISRs.
Dara-SC  will be administered in an outpatient setting. As noted in the Schedule of Activities
(Table 1), vital signs should be monitored extensively on Cycle 1 Day 1 before and after the first
administration of Dara-SC. For all other administrations, vital signs should be measured before the
start of injection and at the end of the injection. If the participant experiences a significant medical
event, then the investigator should assess whether the participant should stay overnight for
observation. If the participant has not experienced a significant medical event but is hospitalized
overnight only for observation, then the hospitalization should not be reported as a SAE.
Dara-SC will be manufactured and provided under the responsibility of the sponsor. Refer to the
IB for a list of excipients. For a definition of study intervention overdose, refer to Section 8.4,
Treatment of Overdose.

6.1.1.1. 
Pre-administration Medication
On days when more than 1 investigational product is administered, the required order of
administration is as follows: dexamethasone (see Section 6.1.2), pre-administration medications
for Dara-SC, Dara-SC, then carfilzomib.
To decrease the risk of IRRs, all participants on Arm B will receive the following medications
1-3 hours prior to each Dara-SC administration:
 An antihistamine: diphenhydramine 25-50 mg IV or PO, or equivalent (see Appendix 13
for list of antihistamines that may be used). Avoid IV promethazine.
 Paracetamol (acetaminophen) 650-1000 mg IV or PO.
 Montelukast 10 mg is recommended on Cycle 1 Day 1 only up to 3 hours prior to the
Dara-SC injection and is optional before all other doses.
If necessary, due to timing constraints, all PO pre-administration medications may be administered
outside of the clinic on the day of the Dara-SC injection, provided they are taken within 1-3 hours
before the injection.
6.1.1.2. 
Post-administration Medication
For participants with a higher risk of respiratory complications (e.g., participants with mild asthma
or participants with COPD who have an FEV1 <80% at screening or developed FEV1 <80%
during the study without any medical history), the following post-injection medications should be
considered:
 Antihistamine
 Short-acting β2 adrenergic receptor agonist such as salbutamol
 Control medications for lung disease (e.g., inhaled corticosteroids ± long-acting β2
adrenergic receptor agonists for participants with asthma; long-acting bronchodilators
such as tiotropium or salmeterol ± inhaled corticosteroids for participants with COPD)
In addition, participants at-risk for respiratory complications may be hospitalized for monitoring
for up to 2 nights after an injection after Dara-SC administration. If participants are hospitalized,
then their FEV1 should be measured before discharge. If these participants are not hospitalized,
then a follow-up telephone call should be made to monitor their condition within 48 hours after all
injections. If the participant has not experienced a significant medical event but is hospitalized
overnight only for observation, then the hospitalization should not be reported as a SAE.
Investigators may prescribe bronchodilators, antihistamines, and corticosteroids that are deemed
necessary to provide adequate supportive care in the event that bronchospasm occurs after a
participant is released from the hospital/clinic. If, after 4 full doses, an at-risk participant
experiences no major IRR, then these post-injection medications may be stopped.

6.1.1.3. 
Management of Injection-site and Infusion-related Reactions
6.1.1.3.1. 
Local Injection-site Reactions
Injection-site reactions are localized reactions at the injection site. In Study MMY1004 Part 1, SC
administration of daratumumab in abdominal SC tissue was associated with local ISRs, such as
induration and erythema, in some participants. The reactions usually resolved within 60 minutes.
Local ISRs should be managed per institutional standards.
6.1.1.3.2. 
Infusion-related Reactions
Infusion-related reactions (IRRs) are systemic reactions related to daratumumab administration.
Participants should be observed carefully during daratumumab administrations. Trained study staff
at the clinic should be prepared to intervene in case of any IRRs, and resources necessary for
resuscitation (e.g., agents such as epinephrine and aerosolized bronchodilator, medical equipment
such as oxygen tanks, tracheostomy equipment, and a defibrillator) must be available at the
bedside. Attention to staffing should be considered when multiple participants will be dosed at the
same time.
If an IRR develops, then Dara-SC administration should be temporarily interrupted. Participants
who experience AEs during Dara-SC  administration must be treated for their symptoms.
Participants should be treated with paracetamol (acetaminophen), antihistamine, or corticosteroids,
as needed. Intravenous saline may be indicated. For bronchospasm, urticaria, or dyspnea,
participants may require antihistamines, oxygen, corticosteroids, or bronchodilators. For
hypotension, participants may require vasopressors. In the event of a life-threatening IRR (which
may include pulmonary or cardiac events) or an anaphylactic reaction, Dara-SC  should be
discontinued.
Infusion-related Reactions of Grade 1 or Grade 2
If the investigator assesses a Grade 1-2 IRR to be related to administration of study intervention,
then the Dara-SC administration should be interrupted. When the participant's condition is stable,
Dara-SC administration may be restarted at the investigator's discretion. Refer to the SIPPM for
further details regarding continuation of Dara-SC administration.
If the participant experiences a Grade 2 or higher event of laryngeal edema, or a Grade 2 or higher
event of bronchospasm that does not respond to systemic therapy and does not resolve within
6 hours from onset, then the participant must be permanently discontinued from Dara-SC
treatment.
Infusion-related Reactions of Grade 3 or Higher
For IRR AEs (other than laryngeal edema or bronchospasm) that are Grade 3, the Dara-SC
administration must be stopped, and the participant must be observed carefully until resolution of
the AE or until the intensity of the event decreases to Grade 1, at which point the Dara-SC
administration may be restarted at the investigator’s discretion. Refer to the SIPPM for further
details regarding continuation of Dara-SC administration.

Approved, Date: 3 June 2021
If the intensity of the AE returns to Grade 3 after restart of the Dara-SC administration, then the
participant must be permanently discontinued from Dara-SC treatment.
For IRR AEs that are Grade 4, the Dara-SC administration must be stopped, and the participant
permanently discontinued from Dara-SC treatment.
Recurrent Infusion-related Reactions
If a Grade 3 IRR (or Grade 2 or higher event of laryngeal edema, or a Grade 2 or higher event of
bronchospasm) recurs during or within 24 hours after a subsequent Dara-SC administration, the
participant must be permanently discontinued from Dara-SC treatment.
6.1.1.4. 
Dose Modification
Dose modification of 1800 mg Dara-SC (increase or decrease) is not permitted. Dose delay is the
primary method for managing daratumumab-related toxicities. On the first day  of each new
treatment cycle and before each dose of study intervention, the participant will be evaluated by
the treating physician for possible toxicities that may have occurred after the previous dose(s).
Toxicities are to be assessed according to NCI-CTCAE, Version 4.03. Cycle delays will be based
on the toxicity experienced during the previous cycle of therapy or newly encountered on Day 1
of a cycle.
If any of the following criteria are met and the toxicity is more than expected for the backbone
therapy (carfilzomib, dexamethasone), or underlying multiple myeloma, the daratumumab
injection must be held to allow for recovery from toxicity as noted below. If attribution is
unclear, then daratumumab should be held until recovery from toxicity as noted below:
 Grade 4 hematologic toxicity, except for Grade 4 lymphopenia
 Grade 3 or higher thrombocytopenia with bleeding
 Febrile neutropenia of any grade
 Neutropenia with infection, of any grade
 Grade 3 or higher nonhematologic toxicities with the following exceptions:
o Grade 3 nausea that responds to antiemetic treatment within 7 days
o Grade 3 vomiting that responds to antiemetic treatment within 7 days
o Grade 3 diarrhea that responds to antidiarrheal treatment within 7 days
o Grade 3 fatigue that was present at baseline or that lasts for <7 days after the last
administration of Dara-SC
o Grade 3 asthenia that was present at baseline or that lasts for <7 days after the last
administration of Dara-SC
o Grade 3 pain associated with symptoms of multiple myeloma (bone/joint pain)

Study intervention should be resumed when the toxicity has resolved to Grade 2. If study
intervention administration does not commence within the prespecified window of the scheduled
administration date (Table 5), then the dose will be considered a missed dose. Administration
may resume at the next planned dosing date. A missed dose will not be made up.

Any dose hold of more than 28 days due to toxicity will result in permanent discontinuation of
Dara-SC. Dose holds of more than 28 days for other reasons should be discussed with the
sponsor. If a dose delay occurs, then PK and pharmacodynamic assessments should be
performed on the actual day of study intervention administration, not on the original scheduled
administration day.
Delay of Day 1 drug dosing in any given cycle should not result in a skipped dose but should
lead to a delay of the entire cycle instead. A minimum of 4 days between Dara-SC doses must be
observed.
A study intervention dose held for more than 3 days from the per-protocol administration date
for any reason other than toxicities suspected to be related to daratumumab should be brought to
the attention of the sponsor at the earliest possible time. Participants missing ≥3 consecutive
planned doses of study intervention for reasons other than toxicity should be withdrawn from
study intervention, unless, upon consultation with the sponsor and the review of safety and
efficacy, continuation is agreed upon.
6.1.2. 
Dexamethasone (Arms A and B)
Dexamethasone 40 mg weekly must be administered as 20 mg by IV infusion or PO on Cycle 1
Day 1, then 20 mg by IV infusion or PO on Cycle 1 Day 2. Dexamethasone 40 mg doses
subsequent to Cycle 1 Day 2 may be administered by IV infusion or PO weekly. For days when
dexamethasone is given in the absence of carfilzomib and in the absence of Dara-SC, it may be
given within ±2 days for each scheduled dose. 
On days when more than 1 investigational product is administered, the required order of
administration is as follows: dexamethasone, pre-administration  medications for Dara-SC,
Dara-SC, then carfilzomib.
For Arm A, dexamethasone will be administered between 30 minutes to 4 hours prior to
carfilzomib followed by carfilzomib dosing.

For Arm B, during weeks when dexamethasone, Dara-SC and carfilzomib will be administered,
dexamethasone will be administered within 1 to 3 hours prior to the Dara-SC, followed by
Dara-SC dosing and then carfilzomib dosing (dexamethasone must be administered no more than
4 hours prior to carfilzomib dosing). During weeks when dexamethasone and Dara-SC will be
administered; dexamethasone will be administered within 1 to 3 hours prior to the Dara-SC,
followed by Dara-SC  dosing. During weeks when dexamethasone and carfilzomib will be
administered, dexamethasone will be administered between 30 minutes to 4 hours prior to
carfilzomib followed by carfilzomib dosing.
6.1.2.1. 
Dexamethasone:  Dosage Adjustments, Dosage Discontinuation
All dexamethasone administrations must be within 2 days of the scheduled administration.
However, it must be given on days carfilzomib or Dara-SC will be administered.
For participants 75 years of age or older, initial starting dexamethasone dose of 20 mg weekly
IV/PO is permitted. Dexamethasone 20 mg weekly must be administered as 20 mg by IV
infusion or PO on Cycle 1 Day 1 and subsequently administered by IV infusion or PO weekly. If
participant is intolerant to dexamethasone 20 mg weekly IV/PO, dose reduction to 12 mg weekly
IV/PO is permitted and may be administered as a split dose over 2 days; 8 mg on the first day
and 4 mg on the second day. If participant is intolerant to dexamethasone 12 mg weekly IV/PO,
dose reduction to 8 mg weekly IV/PO is permitted and must be administered as a single dose.
For participants younger than 75 years of age, or underweight (body mass index [BMI]<18.5), or
who are intolerant to dexamethasone 40 mg once weekly IV/PO, subsequent dexamethasone may
be administered at a split dose of 20 mg twice weekly IV/PO. If a participant is intolerant of a
split dose of 20 mg twice weekly IV/PO, then dexamethasone dose reduction to 20 mg weekly
IV/PO is permitted and may be administered at a split dose of 10 mg twice weekly IV/PO. If
participant is intolerant to dexamethasone 20 mg weekly IV/PO, dose reduction to 12 mg weekly
IV/PO is permitted and may be administered as a split dose over 2 days; 8 mg on the first day
and 4 mg on the second day.
Dexamethasone will be permanently discontinued after 2 dose reductions in the event of
additional dexamethasone-related toxicities. At the investigator’s discretion, dexamethasone may
be tapered prior to complete discontinuation according to institutional practice. The participant
may continue on treatment with the other protocol specified drug(s). Guidelines for
dexamethasone-related toxicities are summarized in Table 6.
Note that the dose modifications above are suggested, but physician discretion and clinical
judgment should prevail.

6.1.3. 
Carfilzomib (Arms A and B)
Carfilzomib will be administered in 28-day cycles. All cycles will start 28 days (±3) after the
start of the prior cycle. Once-weekly carfilzomib must never be administered within the 5 days
following a previous carfilzomib infusion. Carfilzomib IV will be administered at a dose of
20 mg/m2 on Cycle 1 Day 1, then 70 mg/m2 thereafter over 30 minutes (±5 minutes). On days
when more than 1 investigational product is administered, the required order of administration is
as follows: dexamethasone, pre-administration  medications for Dara-SC, Dara-SC, then
carfilzomib.
The amount (in mg) of carfilzomib to be administered will be determined by body surface area
(BSA), which will be calculated according to a standard nomogram (Appendix 14). The
calculated dose of carfilzomib may be rounded to the nearest milligram (eg, a calculated dose of
152.5 mg may be rounded to 153 mg). Additionally, participants with BSA >2.2 m2 should be
given a dose based on a BSA of 2.2 m2. Dose adjustments must be made for weight gains/losses
of ≥20% of baseline body weight.
6.1.3.1. 
Prehydration (for Arm A and Arm B)
Adequate hydration is required prior to dosing in Cycle 1, especially in patients at high risk of
tumor lysis syndrome or renal toxicity. The recommended hydration includes both oral fluids
(30 mL per kg at least 48 hours before Cycle 1 Day 1) and intravenous fluids (250 mL to 500 mL
of normal saline or other appropriate IV fluid prior to each dose in Cycle 1). If needed,
administer an additional 250 mL to 500 mL of intravenous fluids following carfilzomib
administration. Continue oral or intravenous hydration as needed in subsequent cycles, if the
participant’s condition or risk factors require it. Monitor patients for evidence of volume
overload and adjust hydration to the participant's needs, especially in patients with or at risk for
cardiac failure. The total volume of prehydration and the reason for prehydration after Cycle 1
will be recorded.
6.1.3.2. 
Carfilzomib:  Dosage Adjustments, Delays, Rules for Withholding or
Restarting, Permanent Discontinuation
Carfilzomib may be discontinued, temporarily delayed, or dosage temporarily reduced, in the
event of a treatment-related toxicity that, in the opinion of the investigator, warrants the
discontinuation, temporary delay or dose reduction, as indicated in Table 7 and Table 8.  The
participant will be considered on protocol treatment while receiving either carfilzomib or
Dara-SC (ie, if either carfilzomib or Dara-SC are discontinued or interrupted, the participant is
still considered on treatment if still taking the other investigational product). 
If Day 1 of a cycle is delayed, all subsequent doses within the cycle and day 1 of subsequent
cycles should be adjusted accordingly to maintain the 28-day cycle duration.  However, if a
within-cycle dose is delayed, then the dates of the subsequent within-cycle doses should not be
adjusted.  For within-cycle doses, if administration does not commence within the allowable
window of the scheduled administration date, then the dose will be considered a missed dose.

Administration may resume at the next planned dosing date.  A missed dose will not be made up.
Administration may be within ±2 days for each scheduled dose.
If a participant requires an interruption of carfilzomib of more than 4 weeks, the participant
should be removed from study treatment. Exceptions to this must be discussed with the study
medical monitor.

disposed of according to the sponsor's instructions. Study-site personnel must not combine
contents of the study intervention containers.
Study intervention must be handled in strict accordance with the protocol and the container label,
and must be stored at the study site in a limited-access area or in a locked cabinet under
appropriate environmental conditions. Unused study intervention must be available for
verification by the sponsor's study site monitor during on-site monitoring visits. The return to the
sponsor of unused study intervention will be documented on the intervention return form. When
the study site is an authorized destruction unit and study intervention supplies are destroyed
on-site, this must also be documented on the intervention return form.
Potentially  hazardous materials such as used ampules, needles, syringes and vials containing
hazardous liquids, should be disposed of immediately in a safe manner and therefore will not be
retained for intervention accountability purposes.
Study intervention should be dispensed under the supervision of the investigator or a qualified
member of the study-site personnel, or by a hospital/clinic pharmacist. Study intervention will be
supplied only to participants participating in the study. Returned study intervention must not be
dispensed again, even  to the same participant. Study intervention may not be relabeled or
reassigned for use by other participants. The investigator agrees neither to dispense the study
intervention from, nor store it at, any site other than the study sites agreed upon with the sponsor.

Measures to Minimize Bias: Randomization and Blinding
Intervention Allocation
Procedures for Randomization and Stratification
Central randomization will be implemented in this study. Participants will be randomly assigned
to 1 of 2 intervention groups based on a computer-generated randomization schedule prepared
before the study by or under the supervision of the sponsor. The randomization will be balanced
by using randomly permuted blocks and will be stratified by prior protease inhibitor exposure
and daratumumab-free interval (3-6 months, >6 months). The interactive web response system
(IWRS) will assign a unique intervention code, which will dictate the intervention assignment
and matching study intervention kit for the participant. The requestor must use his or her own
user identification and personal identification number when contacting the IWRS and will then
give the relevant participant details to uniquely identify the participant.
Blinding
As this is an open study, blinding procedures are not applicable.
6.4. 
Study Intervention Compliance
Study intervention will be administered by qualified site staff, and the details of each
administration will be recorded in the eCRF. Additional details are provided in the SIPPM or

Concomitant Therapy
Throughout the study, investigators may prescribe any concomitant medications or treatments
deemed necessary to provide adequate supportive care except for those listed in Section 6.5.4.
The sponsor must be notified in advance (or as soon as possible thereafter) of any instances in
which prohibited therapies are administered.
All prestudy antineoplastic and multiple myeloma therapies must be recorded at screening. Other
prestudy therapies administered from the signing of the ICF must be recorded at screening.
Modification of an effective preexisting therapy should not be made for the explicit purpose of
entering a participant into the study.
Routine systemic use of clinically significant concomitant medications will be collected in the
eCRF and recorded in the source documents beginning with signing of the ICF to 30 days after
the last dose of the last component of study intervention or until the start of subsequent
anticancer treatment, if earlier.
Concomitant medications to manage AEs and SAEs will be recorded. Concomitant therapies
should also be recorded beyond 30 days only in conjunction with SAEs that meet the criteria
outlined in SAEs in Section 8.3.1, Time Period and Frequency for Collecting Adverse Events
and Serious Adverse Events Information.
Recorded information will include a description of the type of therapy, duration of use, dosing
regimen, route of administration, and indication.

Required Therapies
6.5.1.1. 
Prophylaxis for Herpes Zoster Reactivation
The initiation of antiviral prophylaxis to prevent herpes zoster reactivation within 1 week after
starting study intervention and continuing for 3 months following study intervention is required.
Acceptable antiviral therapy includes acyclovir (eg, 400 mg given PO 3 times a day, or 800 mg
given PO 2 times a day or per institutional standards), famcyclovir (eg, 125 mg given PO, twice
a day or per institutional standards), or valacyclovir (eg, 500 mg given PO, twice a day or per
institutional standards), initiated within 1 week after the start of study intervention.
6.5.2. 
Recommended Therapies
6.5.2.1. 
Bisphosphonate Therapy
Bisphosphonate therapy is strongly recommended for all participants with evidence of lytic
destruction of bone or with osteopenia. Bisphosphonate therapy is recommended to be continued
per treatment guidelines.16,17 Commercially available IV bisphosphonates (pamidronate and
zoledronic acid) are preferred when available, and should be used according to the
manufacturer's recommendations, as described in the prescribing information, for participants
with osteolytic or osteopenic myelomatous bone disease. Oral bisphosphonates may be used as

alternatives if IV bisphosphonates are not available at the study site. It is preferred that
investigators use the same route of bisphosphonate therapy for all participants at their sites.
Participants who are currently using bisphosphonate therapy when they enter the study should
continue the same treatment.
6.5.2.2. 
Prevention of Steroid Induced Gastritis
Dexamethasone and other steroids may induce gastritis. Medications to prevent gastritis are
strongly recommended. Acceptable therapies include proton pump inhibitors (omeprazole or
equivalent), sucralfate, or H2 blockers (ranitidine or equivalent) initiated within 1 week after the
start of study intervention.
6.5.2.3. 
Therapy for Tumor Lysis Syndrome
Participants should be monitored for symptoms of tumor lysis syndrome. Management of tumor
lysis syndrome, including hydration for abnormal laboratory test results such as hyperkalemia,
hyperuricemia, and hypocalcemia, is highly recommended. High-risk participants (ie, those with
a high tumor burden) should be treated prophylactically in accordance with local standards
(eg, vigorous hydration, diuretics, allopurinol 300 mg daily, and medication to increase urate
excretion).
6.5.2.4. 
Therapy for Pneumocystis carinii/jirovecii
Pneumocystis carinii/jirovecii pneumonia prophylaxis should be considered, as per institutional
guidelines.
6.5.2.5. 
Management of Hepatitis B Virus Reactivation
Primary antiviral prophylaxis is permitted as per local standard of care. Per protocol, HBV DNA
testing by PCR is mandatory for participants at risk for HBV reactivation see Section 8.2.8.
For participants who are diagnosed with HBV reactivation while on treatment, study treatment
should be interrupted until the infection is adequately controlled. If the benefits outweigh the
risks, study treatment may be resumed with concomitant antiviral prophylaxis as per local
standard of care. Consult a liver disease specialist as clinically indicated.
6.5.3. 
Permitted Therapies
Participants are to receive full supportive care during the study. The following medications and
supportive therapies are examples of support therapies that may be used during the study:

Prohibited Therapies
The sponsor must be notified in advance (or as soon as possible thereafter) of any instances of
administration of prohibited therapies. Use of the treatments listed below is prohibited during the
study:
 Concomitant administration of any other antineoplastic therapy for the intention of
treating multiple myeloma is prohibited, including medications that target CD38, as well
as medications used for other indications that have anti-myeloma properties (eg,
interferon and clarithromycin). Continuation of study intervention (during or after
emergency orthopedic surgery or radiotherapy because of participant benefit) may only
occur in the absence of disease progression and after consultation with and approval by
the sponsor.
 Concomitant administration of investigational agents and of commercially available
agents with activity against or under investigation for multiple myeloma are prohibited.
 Systemic corticosteroids (>10 mg dexamethasone per day or equivalent) other than those
given as backbone therapy and for IRRs should be avoided.
 Nonsteroidal anti-inflammatory agents should be avoided to prevent myeloma-related
kidney disease.
 Emergency radiotherapy may consist of localized radiotherapy for pain control or for
stabilization of an extensive bone lesion at high risk of pathologic fracture or damage to
surrounding tissues in a participant for whom delay of systemic therapy is not
appropriate, but radiotherapy field must not include a measurable extramedullary
plasmacytoma. Radiotherapy must occur within the first 2 cycles of study intervention
and only if disease progression has not occurred. Before radiotherapy, the sponsor will
review the participant data and confirm that disease progression has not occurred.
 Administration of live-attenuated and replication-competent viral vector vaccines are
prohibited.
6.6. 
Intervention After the End of the Study
The sponsor will ensure that participants benefiting from study treatment will be able to continue
receiving Dara-SC and carfilzomib after the end of the study until these agents are commercially
available or available from another source. Subsequent therapy is left to the investigator's
discretion.  Subsequent therapy should be documented in the CRF.

A participant will be considered to have completed the study if he or she has finished all
protocol-specified procedures before the end of the study, has not been lost to follow-up, died,
and has not withdrawn consent for study participation before the end of the study.
7.2. 
Discontinuation of Study Intervention
A participant will not be automatically withdrawn from the study if he or she has to discontinue
intervention. The End-of-Treatment Visit and Follow-up visit assessments should continue as
specified in Schedule of Activities (Table 1).
A participant's study intervention must be discontinued if:
 
The investigator believes that for safety reasons or tolerability reasons (eg, AE) it is in
the best interest of the participant to discontinue all study interventions. End of
treatment is defined as discontinuation of all study interventions. Participants who
discontinue one of the 3 study interventions may continue the other study interventions.
 
The participant becomes pregnant unless the participant, investigator, and sponsor agree
the benefits outweigh the risks to the fetus and continuation of study intervention is in
the best interests of the participant. Refer to Appendix 6.
 
The participant withdraws consent for administration of additional study intervention
 
The participant starts concurrent (non-protocol) treatment for multiple myeloma
 
The participant experiences intolerable toxicity, including IRRs (see Section 6.1.1.3)
 
The participant experiences disease progression as defined by IMWG criteria (see
Table 10). Neither relapse from CR nor clinical relapse are considered as disease
progression.
 
The participant experiences a second primary malignancy that cannot be treated by
surgery alone. However, a participant who develops a malignancy that can be cured
surgically may continue to receive the assigned study treatment and should continue to
be followed for subsequent progression of multiple myeloma.
 
The participant initiates treatment with a prohibited medication.
If a participant discontinues study intervention for any reason before the end of the Treatment
Phase, disease assessments should be obtained and scheduled assessments should be continued
until disease progression is confirmed. The participant will complete the End-of-Treatment Visit
and enter the Follow up Phase. Follow-up will continue until the end of study. If the reason for
withdrawal from the study is withdrawal of consent then no additional assessments are allowed.
The primary reason for discontinuation of study treatment is to be recorded in the CRF.
7.3. 
Participant Discontinuation/Withdrawal from the Study
A participant will not be automatically withdrawn from the study if they have to discontinue
study intervention before the end of the intervention regimen.
A participant will be withdrawn from the study for any of the following reasons:

 Lost to follow-up
 Withdrawal of consent
 Death
 The study investigator or sponsor for any reason, stops the study or stops the participant’s
participation in the study
When a participant withdraws before completing the study, the reason for withdrawal is to be
documented in the eCRF and in the source document. Study intervention assigned to the
withdrawn participant may not be assigned to another participant. Additional participants will
not be entered. If a participant discontinues study intervention and withdraws from the study
before the end of the Treatment Phase, End-of-Treatment and Follow-up assessments should be
obtained. If the reason for withdrawal from the study is withdrawal of consent to study
intervention and all procedures and follow-up, then no additional assessments are allowed.
7.4. 
Lost to Follow-up
If a participant is lost to follow-up, every reasonable effort must be made by the study site
personnel to contact the participant and determine the reason for discontinuation/withdrawal. The
measures taken to follow up must be documented. Refer to Section  7.3, Participant
Discontinuation/Withdrawal from the Study.

STUDY ASSESSMENTS AND PROCEDURES
Overview
The Schedule of Activities (Table 1 to Table 3) summarizes the frequency and timing of
efficacy, PK, immunogenicity, biomarker, medical resource utilization, and safety.
Urine and blood collections for PK assessments should be kept as close to the specified time as
possible. Other measurements may be done earlier than specified timepoints if needed. Actual
dates and times of assessments will be recorded in the source documentation and eCRF.
Additional serum or urine pregnancy tests may be performed, as determined necessary by the
investigator or required by local regulation, to establish the absence of pregnancy at any time
during the participation in the study.
Medical resource utilization data will be collected. Refer to Section 8.7, Medical Resource
Utilization for details.

The total blood volume (based on a median of 16 cycles) is 766 mL. This includes screening,
cycles inclusive of safety, blood typing, daratumumab PK and immunogenicity and rHuPH20
immunogenicity, biomarkers, disease evaluations and pregnancy testing and EOT and follow up.
Repeat or unscheduled samples may be taken for safety reasons or for technical issues with the
samples.
Sample Collection and Handling
Refer to the Schedule of Activities (Table 1 to Table 3) for the timing and frequency of all
sample collections. The actual dates and times of sample collection must be recorded in the
eCRF or laboratory requisition form. If blood samples are collected via an indwelling cannula, an
appropriate amount (1 mL) of serosanguineous fluid slightly greater than the dead space volume
of the lock will be removed from the cannula and discarded before each blood sample is taken.
After blood sample collection, the cannula will be flushed with  0.9% sodium chloride, US
Pharmacopeia (or equivalent) sodium heparin of 10 U/mL and charged with a volume equal to
the dead space volume of the lock. If a mandarin (obturator) is used, blood loss due to discard is
not expected.
Instructions for the collection, handling, storage, and shipment of samples are found in the
laboratory manual that will be provided. Collection, handling, storage, and shipment of samples
must be under the specified, and where applicable, controlled temperature conditions as indicated
in the laboratory manual.
Study-Specific Materials
The investigator will be provided with the following supplies:
 IBs for daratumumab and carfilzomib
 Investigational Product Preparation Instructions
 Site Investigational Product Procedures Manual
 Laboratory manual

During study treatment, disease evaluations must be performed every 28 days (±7 days) until
disease progression. If a participant discontinues study treatment for reasons other than disease
progression, disease evaluations should be conducted every 8 weeks (±7 days) until confirmed
disease progression, death, start of a new treatment for multiple myeloma, withdrawal of
consent, or the end of the study, whichever occurs first. Disease evaluations will be performed by
a central laboratory (unless otherwise specified). This study will use the IMWG consensus
recommendations for multiple myeloma treatment response criteria8,11,21 presented in Table 10.
All serum and urine disease evaluations will be performed by a central laboratory according to
Section 1.3. For quantitative immunoglobulin, M-protein, and immunofixation measurements in
serum and 24-hour urine, the investigator will use results provided by the central laboratory. For
participants with light chain multiple myeloma, only serum FLC assay will be performed
routinely. Otherwise, serum FLC assay test results will be analyzed by the central laboratory
only for the assessment of sCR. For participants with suspected daratumumab interference on
serum M-protein quantitation by electrophoresis (SPEP) and immunofixation, a reflex assay will
be performed (Appendix 15). Participants with confirmed daratumumab interference who meet
all other clinical criteria for CR or sCR will be considered CR/sCR.

International Uniform Response Criteria Consensus Recommendations
Progressive 
disease (PD)† 
 
Increase of 25% from lowest response value in any one of the following:
 
Serum M-component (absolute increase must be ≥0.5 g/dL),
 
Urine M-component (absolute increase must be ≥200 mg/24 hours),
 
Only in participants without measurable serum and urine M-protein levels: the difference
between involved and uninvolved FLC levels (absolute increase must be >10 mg/dL)
 
Only in participants without measurable serum and urine M-protein levels and without
measurable disease by FLC levels, bone marrow PC percentage irrespective of baseline
status; the absolute percentage must be ≥10%
 
Definite development of new bone lesions or soft tissue plasmacytomas or definite
increase in the size of existing bone lesions or soft tissue plasmacytomas
 
Development of hypercalcemia (corrected serum calcium >11.5 mg/dL) that can be
attributed solely to the PC proliferative disorder
CR complete response; FLC free light chain; IMWG International Myeloma Working Group; M protein monoclonal
paraprotein; MR minimal response; PC plasma cell; PD progressive disease; PR partial response; sCR stringent complete
response; SD stable disease; VGPR very good partial response
All response categories (CR, sCR, VGPR, PR, and PD) require 2 consecutive assessments made at any time before the institution
of any new therapy; CR, sCR, VGPR, PR, and SD categories also require no known evidence of progressive or new bone lesions
if radiographic studies were performed. VGPR and CR categories require serum and urine studies regardless of whether disease
at baseline was measurable on serum, urine, both, or neither.
Radiographic studies are not required to satisfy these response requirements. Bone marrow assessments need not be confirmed.
For PD, serum M component increases of more than or equal to 1 g/dL are sufficient to define relapse if starting M component is
≥5 g/dL.
* Clarifications to IMWG criteria for coding CR and VGPR in participants in whom the only measurable disease is by serum
FLC levels: CR in such participants indicates a normal FLC ratio of 0.26 to 1.65 in addition to CR criteria listed above. VGPR
in such participants requires a >90% decrease in the difference between involved and uninvolved FLC levels.
† Clarifications to IMWG criteria for coding PD: Bone marrow criteria for PD are to be used only in participants without
measurable disease by M protein and by FLC levels; “25% increase” refers to M protein, FLC, and bone marrow results, and
does not refer to bone lesions, soft tissue plasmacytomas, or hypercalcemia and the “lowest response value” does not need to
be a confirmed value.
a Presence/absence of clonal cells is based upon the kappa/lambda ratio. An abnormal kappa/lambda ratio by
immunohistochemistry or immunofluorescence requires a minimum of 100 plasma cells for analysis. An abnormal ratio
reflecting presence of an abnormal clone is kappa/lambda of >4:1 or <1:2.
Clinical Relapse
Clinical relapse is defined using the definition of clinical relapse in IMWG criteria.9,11,21 In IMWG criteria, clinical relapse is
defined as requiring one or more of the following direct indicators of increasing disease or end organ dysfunction that are
considered related to the underlying plasma cell proliferative disorder:
1. Development of new soft tissue plasmacytomas or bone lesions on skeletal survey, magnetic resonance imaging, or other
imaging
2. Definite increase in the size of existing plasmacytomas or bone lesions. A definite increase is defined as a 50% (and at least
1 cm) increase as measured serially by the sum of the products of the cross diameters of the measurable lesion
3. Hypercalcemia (>11.5 mg/dL; >2.875mM/L)
4. Decrease in hemoglobin of more than 2 g/dL (1.25 mM) or to less than 10 g/dL
5. Rise in serum creatinine by more than or equal to 2 mg/dL (≥177 mM/L)
6. Hyperviscosity
In some participants, bone pain may be the initial symptom of relapse in the absence of any of the above features. However, bone
pain without imaging confirmation is not adequate to meet these criteria in studies.

Approved, Date: 3 June 2021
Disease progression must be consistently documented across clinical study sites using the criteria
in Table 10. Disease evaluations will continue beyond relapse from CR until disease progression
is confirmed. It is important that instances of disease progression be reported to the sponsor as
soon as possible. Diagnosis and documentation of disease progression will be reported to the
sponsor within 24 hours of suspected disease progression. The medical monitor will review the
information to confirm that the IMWG criteria for disease progression have been met. If the
medical monitor agrees that disease progression has occurred, then a confirmation will be
returned to the investigator, and the participant will be withdrawn from study intervention. If the
medical monitor considers that the IMWG criteria for disease progression have not been met,
then the medical monitor will contact the investigator to discuss the participant.
For continuation of study intervention, the IMWG response will be determined on an ongoing
basis by the investigator. For data analysis and reporting, however, the sponsor will use a
validated computer algorithm that has been shown to provide consistent review of the data
necessary to determine disease progression and response according to IMWG criteria.
For participants who discontinue study intervention before disease progression, disease
evaluations should continue to be performed as described in the Schedule of Activities (Table 1
to Table 3), until confirmed disease progression, death, start of a new treatment for multiple
myeloma, withdrawal of consent, or the end of the study, whichever occurs first. Blood and urine
for disease evaluations scheduled for treatment days should be collected before study
intervention is administered.
8.1.2. 
Myeloma Protein Measurements in Serum and Urine
Blood and 24-hour urine samples will be collected as specified in the Schedule of Activities
(Table 1 to Table 3) until the development of confirmed disease progression. Samples for
M-protein measurements will be sent to and analyzed by a central laboratory. Only one serum
and one 24-hour urine sample per time point are required by the central laboratory to perform the
following tests:
 Serum Quantitative Immunoglobulins: All participants will be evaluated for IgG,
immunoglobin A (IgA), immunoglobin M (IgM), immunoglobin D (IgD), and
immunoglobin E (IgE) at screening. During the study, participants with IgD or IgE
disease will be evaluated for IgG, IgA, IgM, IgE, and IgD and participants with IgG, IgA,
or IgM disease will be evaluated for IgG, IgA, and IgM.
 Serum M-Protein quantification by electrophoresis (SPEP)
 Serum immunofixation at screening and thereafter when a CR is suspected. If
daratumumab interference is suspected based on SPEP and immunofixation
electrophoresis (IFE) results, additional reflex IFE testing may be performed.
 Serum FLC assay
 24-hour urine M-protein quantitation by electrophoresis (UPEP)
 Urine immunofixation at screening and thereafter when a CR is suspected

Approved, Date: 3 June 2021
Disease progression based on one of the laboratory tests alone must be confirmed by at least one
repeat investigation.
Participants with a urine M-protein on UPEP >100 mg/24h at screening will provide samples for
UPEP assessment on the same schedule as SPEP throughout the study according to the Schedule
of Activities (Table 1).  Blood samples for SPEP and SIFE must be collected on the same day
that 24-hour urine samples for UPEP and UIFE starts or stops. Participants may stop collecting
samples for UPEP assessments after Cycle 1 Day 1 only if 1) they have urine M-protein
<100 mg/24h at screening, or 2) they have measurable urine M-protein >100 mg/24h at
screening but then urine M-protein <100 mg/24h at 2 consecutive post-baseline
measurements. A urine sample for UPEP assessment should be obtained to document VGPR,
CR, and sCR and at suspected disease progression for all participants with measurable disease by
SPEP or UPEP (non-FLC), regardless of UPEP collection exemptions as described above.
Serum and urine immunofixation tests and serum FLC assay will be performed at screening,
Day 1 of each cycle, and thereafter when a CR is suspected (when serum or 24-hour urine
M-protein electrophoresis [by SPEP or UPEP] are 0 or nonquantifiable). For participants with
suspected daratumumab interference on serum immunofixation, another reflex assay using the
anti-idiotype mAb will be used to confirm daratumumab migration on immunofixation.
Participants that meet all other IMWG criteria for CR, and whose positive immunofixation is
confirmed to be daratumumab, will be considered complete responders. However, for
participants with light chain multiple myeloma, serum FLC assay will be performed routinely.
Serum immunofixation assay samples will be split into 2 aliquots, with 1 reserved for potential
follow-on testing if daratumumab interference with immunofixation is suspected. As
daratumumab is a monoclonal IgG antibody, additional serum samples may be utilized to
monitor for potential daratumumab interference with immunofixation.
Note: All attempts should be made to determine eligibility of the participant based on the central
laboratory results of screening blood and urine M-protein measurements. In exceptional
circumstances, the local laboratory results of blood and urine M-protein measurements may be
used to determine eligibility, but only if the results are clearly (eg, 25% or more) above the
thresholds for measurability. In such cases, central laboratory results are still required to be
obtained in order to establish baseline values and confirm the results from the local laboratory.
8.1.3. 
Serum Calcium Corrected for Albumin
Blood samples for calculating serum calcium corrected for albumin will be collected as specified
in the Schedule of Activities (Table 1) and analyzed centrally until the development of confirmed
disease progression. Development of hypercalcemia (corrected serum calcium >11.5 mg/dL or
2.8 mmol/L) can indicate disease progression or relapse if it is not attributable to any other cause
(see disease response criteria in Table 10). Calcium binds to albumin and only the unbound (free)
calcium is biologically active; therefore, the serum calcium level must be adjusted for abnormal
albumin levels (“corrected serum calcium”). The formula for adjustment is presented in
Appendix 9.

Approved, Date: 3 June 2021
When blood is analyzed at a local laboratory, measurement of free ionized calcium is an
acceptable alternative to corrected serum calcium to determine hypercalcemia. Free ionized
calcium levels greater than the ULN (local laboratory reference ranges) are considered to be
hypercalcemic for this study.
8.1.4. 
β2-microglobulin and Albumin
Blood samples for β2-microglobulin and albumin are to be collected at screening and will be
analyzed by the central laboratory and used for the assessment of International Staging System
staging at study entry. The central laboratory will also measure albumin at any time during the
study that a serum calcium sample is taken.
8.1.5. 
Bone Marrow Examination
Bone marrow assessments to be performed locally and centrally are summarized in Table 3.
MRD evaluation will be performed centrally, while the cytogenetic analysis will be performed
locally. If cytogenetic analysis is not available locally, this may be done centrally with agreement
of the sponsor. The following FISH probes should be used for cytogenetic analysis:
 Required: t(4;14); t(14;16), del (17p)
 Optional: Amplification 1q
8.2. 
Safety Assessments
AEs will be reported and followed by the investigator as specified in Section 8.3, Adverse
Events and Serious Adverse Events and Appendix 5. Any clinically relevant changes occurring
during the study must be recorded on the AE section of the eCRF. Any clinically significant
abnormalities persisting at the end of the study/early withdrawal will be followed by the
investigator until resolution or until a clinically stable condition is reached.
The study will include the following evaluations of safety and tolerability according to the time
points provided in the Schedule of Activities (Table 1).
8.2.1. 
Physical Examination
A complete physical examination (including neurological examination) should be performed
during screening. Thereafter, a physical examination  that is symptom- and disease-directed as
clinically indicated is to be performed at each treatment visit. Abnormalities will be recorded in
the appropriate section of the eCRF.
8.2.2. 
Vital Signs
Temperature, pulse/heart rate, respiratory rate, and blood pressure will be assessed.
Blood pressure and pulse/heart rate measurements will be assessed sitting with a completely
automated device. Manual techniques will be used only if an automated device is not available.

Blood pressure and pulse/heart rate measurements should be preceded by at least 5 minutes of
rest in a quiet setting without distractions (eg, television, cell phones).
8.2.3. 
Electrocardiogram
During the collection of ECGs, participants should be in a quiet setting without distractions (eg,
television, cell phones). Participants should rest in a supine position for at least 5 minutes before
ECG collection and should refrain from talking or moving arms or legs. If blood sampling or
vital sign measurement is scheduled for the same time point as ECG recording, the procedures
should be performed in the following order: ECG(s), vital signs, blood draw.
8.2.4. 
Clinical Safety Laboratory Assessments
Blood samples for serum chemistry and hematology will be collected as noted in Appendix 3.
The investigator must review the laboratory results, document this review, and record any
clinically relevant changes occurring during the study in the AE section of the eCRF. The
laboratory reports must be filed with the source documents.
8.2.5. 
Pulmonary Function Test
Participants with known or suspected COPD must have a spirometry FEV1 test during screening.
8.2.6. 
Indirect Antiglobulin Test
Blood group and type, Rh, and IAT should be done before the first dose of Dara-SC. Participant
RBC phenotyping (standard or extended) is an alternative option to the IAT test, if locally
required. Either method must be completed prior to first study intervention administration.
Daratumumab interferes with the IAT, which is a routine pre-transfusion test performed to
identify a participant's antibodies to minor antigens so that suitable donor blood can be given for
transfusion. Daratumumab does not interfere with ABO/rhesus D antigen (RhD) typing. CD38 is
expressed at very low levels on erythrocytes. Daratumumab binds to the CD38 on erythrocytes,
which results in a positive IAT (Indirect Coombs Test). This positive result masks the detection
of antibodies to minor antigens and may prevent or delay blood banks from issuing donor blood
for transfusion. This effect occurs during daratumumab treatment and for up to 6 months after
treatment ends. Participants will receive a participant identification wallet card for the study that
includes the blood profile (ABO, Rh, and IAT or phenotyping) determined before the first study
intervention administration, along with information on the IAT interference for healthcare
providers/blood banks. Participants are to carry this card throughout the Treatment Phase and for
at least 6 months after study intervention ends. Blood banks can eliminate the daratumumab
interference with IAT by treating reagent RBCs with dithiothreitol.4,5
Possible methods for blood banks to provide safe RBCs for transfusion to participants receiving
daratumumab include:
a. Providing ABO/RhD compatible, phenotypically (standard or extended phenotyping) or
genotypically matched units

b. Providing ABO/RhD compatible, K-negative units after ruling out or identifying
alloantibodies using dithiothreitol-treated reagent RBCs
Uncrossmatched, ABO/RhD compatible RBC units should be administered if transfusion is
needed emergently as per local blood bank practice.
Despite daratumumab binding to CD38 on erythrocytes, no indication of clinically significant
hemolysis has been observed in daratumumab studies. For additional details, refer to the
daratumumab IB
8.2.7. 
HBV Serology
All participants will be tested locally for hepatitis B surface antigen (HBsAg), hepatitis B surface
antibody (Anti-HBs), and hepatitis B core antibody (Anti-HBc) at Screening unless this was
performed as part of standard of care within 3 months prior to first dose.
8.2.8. 
HBV-DNA Test
Participants who are positive for Anti-HBc or Anti-HBs will undergo testing for hepatitis B
DNA by PCR. Participants with serologic findings suggestive of HBV vaccination (Anti-HBs
positivity as the only serologic marker) and a known history of prior HBV vaccination do not
need to be tested for HBV DNA by PCR. During and following study treatment, participants
who have history of HBV infection will be closely monitored for clinical and laboratory signs of
reactivation of HBV as specified in the Schedule of Activities (Table 1). Where required by local
law, the results of HBV testing may be reported to the local health authorities.
8.2.9. 
Eastern Cooperative Oncology Group Performance Status
ECOG performance status will be used to evaluate the effect of the disease status on the
activities of daily living. When scheduled, ECOG Performance Status assessments should be
obtained prior to any other study procedures planned for the same day whenever possible.
8.2.10. 
Transthoracic Echocardiogram or Multiple-Gated Acquisition Scan
Participants must have a transthoracic echocardiogram  (TTE) or Multiple-Gated acquisition
(MUGA) scan according to the Schedule of Activities (Table 1) showing left ventricular ejection
fraction >40%. A trans-esophageal echocardiogram (TEE) will be an acceptable alternative to
TTE or MUGA if performed as part of standard of care.
8.3. 
Adverse Events and Serious Adverse Events
Timely, accurate, and complete reporting and analysis of safety information from clinical studies
are crucial for the protection of participants, investigators, and the sponsor, and are mandated by
regulatory agencies worldwide. The sponsor has established Standard Operating Procedures in
conformity with regulatory requirements worldwide to ensure appropriate reporting of safety
information; all clinical studies conducted by the sponsor or its affiliates will be conducted in
accordance with those procedures.

All AEs and special reporting situations, whether serious or non-serious, will be reported from
the time a signed and dated ICF is obtained until 30 days after the last dose of study intervention;
during the follow-up phase, only treatment-related SAEs will be reported. The sponsor will
evaluate any safety information that is spontaneously reported by an investigator beyond the time
frame specified in the protocol.
Serious Adverse Events
All SAEs occurring during the study must be reported to the appropriate sponsor contact person
by study-site personnel within 24 hours of their knowledge of the event.
Information regarding SAEs will be transmitted to the sponsor using the Serious Adverse Event
eCRF, which must be completed and reviewed by a physician from the study site, and
transmitted to the sponsor within 24 hours. In the event that the Serious Adverse Event eCRF
cannot be completed, information regarding SAEs will be transmitted to the sponsor using the
Serious Adverse Event Form, which must be completed and signed by a physician from the study
site and transmitted to the sponsor within 24 hours. The initial and follow-up reports of a serious
adverse event should be transmitted electronically or by facsimile (fax).
8.3.2. 
Follow-up of Adverse Events and Serious Adverse Events
Adverse events, including pregnancy, will be followed by the investigator as specified in
Appendix 5.
8.3.3. 
Regulatory Reporting Requirements for Serious Adverse Events
The sponsor assumes responsibility for appropriate reporting of AEs to the regulatory authorities.
The sponsor will also report to the investigator (and the head of the investigational institute
where required) all suspected unexpected serious adverse reactions (SUSARs). For anticipated
events reported as individual SAEs, the sponsor will make a determination of relatedness in
addition to and independent of the investigator’s assessment. The sponsor will periodically
evaluate the accumulating data and, when there is sufficient evidence and the sponsor has
determined there is a reasonable possibility that the intervention caused a serious anticipated
event, they will submit a safety report in narrative format to the investigators (and the head of the

institute where required). The sponsor assumes responsibility for appropriate reporting of
anticipated events to the regulatory authorities according to requirements of the countries in
which the studies are conducted. The investigator (or sponsor where required) must report
SUSARs to the appropriate Independent Ethics Committee/Institutional Review Board
(IEC/IRB) that approved the protocol unless otherwise required and documented by the
IEC/IRB.
8.3.4. 
Pregnancy
All initial reports of pregnancy in female participants or partners of male participants must be
reported to the sponsor by the study-site personnel within 24 hours of their knowledge of the
event using the appropriate pregnancy notification form. Abnormal pregnancy outcomes (eg,
spontaneous abortion, fetal death, stillbirth, congenital anomalies, ectopic pregnancy) are
considered SAEs and must be reported using the Serious Adverse Event Form. Any participant
who becomes pregnant during the study must be promptly withdrawn from the study and
discontinue further study intervention unless the participant, investigator, and sponsor agree the
benefits outweigh the risks to the fetus and continuation of study intervention  is in the best
interests of the participant. Follow-up information regarding the outcome of the pregnancy and
any postnatal sequelae in the infant will be required.
8.3.5. 
Disease-Related Events and Disease-Related Outcomes That Do Not
Need to be Reported as Adverse Events or Serious Adverse Events
Expected progression of disease should not be considered an AE (or SAE). However, if
determined by the investigator to be more likely related to the study treatment than the
underlying disease, the clinical signs or symptoms of progression and the possibility that the
study treatment is enhancing disease progression, should be reported per the usual reporting
requirements.
8.4. 
Treatment of Overdose
No maximum tolerated dose has been reached for daratumumab. However, if the dose exceeds
the maximum tested dose of 2000 mg, then it will be considered as an overdose in this study.
In the event of an overdose, the investigator or treating physician should:
 Contact the Medical Monitor immediately.
 Closely monitor the participant for AE/SAE and laboratory abnormalities until
daratumumab can no longer be detected systemically (at least 3 months).
 Document the quantity of the excess dose as well as the duration of the overdosing in the
eCRF.
Decisions regarding dose interruptions or modifications will be made by the investigator in
consultation with the Medical Monitor based on the clinical evaluation of the participant.

Approved, Date: 3 June 2021
Serum samples will be used to evaluate the PK of daratumumab. Serum collected for PK may
additionally be used to evaluate safety or efficacy aspects that address concerns arising during or
after the study period. Genetic analyses will not be performed on these serum samples.
Participant confidentiality will be maintained.
8.5.1. 
Evaluations
Venous blood samples will be collected for measurement of serum concentrations of
daratumumab and anti-daratumumab antibodies according to the Schedule of Activities (Table 1
and Table 2).
Samples will also be collected from all participants in Arm B to evaluate the immunogenicity of
rHuPH20 according to Table 2.
Venous blood samples will be collected, and each serum sample will be divided into 3 aliquots
(1 each for PK, anti-daratumumab antibodies, and a back-up). Samples collected for analyses of
daratumumab serum concentration and antibody to daratumumab may additionally be used to
evaluate safety or efficacy aspects that address concerns arising during or after the study period.
Genetic analyses will not be performed on these serum samples. Participant confidentiality will
be maintained. Additional information about the collection, handling, and shipment of biological
samples can be found in the Laboratory Manual.
8.5.2. 
Analytical Procedures
Pharmacokinetics
Serum samples will be analyzed to determine concentrations of daratumumab using a validated,
specific, and sensitive immunoassay method by or under the supervision of the sponsor.
Immunogenicity
For the daratumumab immunogenicity assessments, serum samples will be screened for
antibodies binding to daratumumab and serum titer will also be determined from confirmed
positive samples. Other immunogenicity analyses (eg, assessment of neutralizing capabilities)
may be performed to further characterize the immune responses that are generated.
For the rHuPH20 immunogenicity assessments, plasma samples will be screened for antibodies
binding to rHuPH20 and will be assessed in confirmatory and titer assays as necessary.
Neutralizing antibody assessments may also be performed to further characterize immune
responses that are generated.
8.5.3. 
Pharmacokinetic Parameters and Evaluations
Parameters
The trough concentrations will be reported by visit and treatment. Data from this study may be
pooled with other studies to conduct a population PK analysis of serum concentration-time data

of daratumumab. If performed, details will be provided in a population PK analysis plan and
results of the analysis will be presented in a separate report.
Pharmacokinetic/Pharmacodynamic Evaluations
If sufficient data are available, then other PK/pharmacodynamic modeling may be performed,
including exploring the relationship between serum concentrations of daratumumab and
endpoints of clinical efficacy and safety. If these analyzes are performed, then the details and
results will be presented in a separate report.
8.5.4. 
Immunogenicity Assessments
Daratumumab concentration will be evaluated at all immunogenicity time points to ensure
appropriate interpretation of immunogenicity data. When both daratumumab serum
concentration and immunogenicity analyses are specified, they will be performed on aliquots
from the same blood draw and no additional sampling is required. Plasma samples will also be
collected from all participants receiving daratumumab (Arm B) and assessed for anti-rHuPH20
antibodies. Procedures for sample collection, preparation, identification, storage, and shipment
will be provided in the Laboratory Manual or equivalent document.
When an IRR occurs associated with daratumumab administration, 2 blood samples should be
obtained, if possible, for determination of antibodies to daratumumab and antibodies to
rHuPH20. Daratumumab serum concentration will also be determined from the daratumumab
IRR sample for interpreting immunogenicity data. If the infusion  reaction results in treatment
discontinuation, then participants should undergo all scheduled safety and efficacy evaluations.
Procedures for sample collection, preparation, identification, storage, and shipment will be
provided in the Laboratory Manual or equivalent document. Samples collected for the analysis of
daratumumab immunogenicity/serum concentration or rHuPH20 immunogenicity may be used to
evaluate safety or efficacy questions that arise during or after the study period or for the
evaluation of relevant biomarkers by the sponsor or sponsor’s designee.
Participants who discontinue study intervention or withdraw from the study before confirmation
of PD should have samples collected at the time of early discontinuation. Participants who
discontinue study intervention will also be asked to return for immunogenicity evaluation during
the Follow-up Phase.
8.6. 
Biomarkers
Bone marrow aspirate samples collected at screening will be subjected to DNA sequencing to
establish a multiple myeloma clone for MRD monitoring (calibration). MRD assessment by via
the FDA cleared clonoSEQ V2.0 next generation sequencing (NGS) for the assessment of MRD
for patients with multiple myeloma and several studies have demonstrated that MRD status is
correlated with PFS and OS.12,14 In this study, bone marrow samples will be collected when a
bone marrow aspirate is performed at screening and at the subsequent points outlined in  the
Schedule of Activities (Table 1 and Table 3). Bone marrow aspirates will be utilized for
assessment of MRD by NGS of immunoglobulin heavy and light chains as specified. If this

methodology is unavailable, or determined to be scientifically inferior, then alternative methods
for MRD assessment may be utilized.
Whole blood samples will be collected from participants as outlined in the Schedule of Activities
(Table 1) and processed to isolate plasma and peripheral blood mononuclear cell (PBMCs).
Changes in immune subpopulations; including T cells (cytotoxic, regulatory memory), B cells,
NK cells and myeloid derived suppressor cells, as a result to treatment with daratumumab, could
be contributing factors to its duration of response. Therefore, subsequent PD might come as a
result of alterations in the daratumumab-induced equilibrium. The data will be analyzed using
mass cytometry (CyTOF) and fluorescence-activated cell sorting and in association with clinical
data may be examined to identify specific signatures associated with response and resistance.
8.7. 
Medical Resource Utilization
Medical resource utilization data, associated with medical encounters, will be collected in the
eCRF by the investigator and study-site personnel for all participants throughout the study.
Protocol-mandated procedures, tests, and encounters are excluded. The data collected may be
used to conduct exploratory economic analyses and will include:
 Number and duration of medical care encounters, including surgeries, and other selected
procedures (inpatient and outpatient)
 Duration of hospitalization (total days length of stay, including duration by wards;
eg, intensive care unit)
 Number and character of diagnostic and therapeutic tests and procedures
 Outpatient medical encounters and treatments (including physician or emergency room
visits, tests and procedures, and medications)
9. 
STATISTICAL CONSIDERATIONS
Statistical analysis will be done by the sponsor or under the authority of the sponsor. A general
description of the statistical methods to be used to analyze the efficacy and safety data is outlined
below. Specific details will be provided in the Statistical Analysis Plan.
9.1. 
Statistical Hypotheses
Dara-SC in combination with Kd will have a higher VGPR or better rate as the best response
than Kd in participants who have previously received 1 to 3 prior line(s) of therapy including
daratumumab.
9.2. 
Sample Size Determination
Based on Study MMY1001 study data, the rate of VGPR or better as the best response was 68%
for DKd participants not previously treated with daratumumab. If VGPR or better rate is
assumed to be 60% for DKd and 45% for Kd in the current study, 230 participants (assigned 1:1)
are needed in order to detect an absolute 15% increase in VGPR or better rate with 70% power
using a 2-sided chi-squared test at the 10% significance level.

Approved, Date: 3 June 2021
9.3. 
Populations for Analyses
Analysis of the primary and secondary efficacy endpoints will be based on the
intent-to-treat (ITT) analysis set, which will include all randomized participants. All safety
analyses are to be performed on data from the all treated analysis set, which will include all
participants who received at least 1 dose of study intervention. Pharmacokinetic analyses will be
performed on the PK-evaluable population, defined as participants who have at least one PK
sample concentration value.
9.4. 
Statistical Analyses
9.4.1. 
Efficacy Analyses
The primary endpoint of VGPR rate or better is defined as the proportion of participants who
achieve VGPR, CR, or sCR as the best response according to the IMWG criteria, after initial
dose of study intervention and before disease progression or start of subsequent anti-myeloma
treatment. The rate of VGPR or better will be compared between the treatment arms using the
stratified Cochran-Mantel-Haenszel test. The stratification factors are prior PI exposure and
daratumumab-free interval (3-6 months, >6 months) at randomization.
Categorical secondary endpoints including ORR, rate of CR/sCR, and MRD negativity rate, will
be analyzed similarly as the primary endpoint. The time-to-event efficacy  endpoints, such as
PFS, OS, and time to next treatment, will be analyzed using the Kaplan-Meier method.
The primary analysis will be carried out with a 2-sided alpha level of 0.10. The secondary
efficacy  analyses will be carried out using 2-sided alpha level of 0.10 without multiplicity
adjustment.
The primary analysis will be conducted approximately 6 months after the last participant
receives the initial dose of study intervention. An interim futility analysis will occur when 40%
of participants are enrolled and treated for 6 months. A final analysis will occur at study
completion/end of the study to update PFS, survival, second primary malignancy and safety.
9.4.2. 
Safety Analyses
The baseline value for safety assessment is defined as the value collected at the time closest to,
but prior to, the start of study intervention administration. The safety parameters to be evaluated
are the incidence, severity, and type of AEs, clinically significant changes in the participant’s
physical examination findings, vital signs measurements, and clinical laboratory results.
Exposure to investigational product and reasons for discontinuation of study intervention will be
tabulated.
Adverse Events
The verbatim terms used in the eCRF by investigators to identify AEs will be coded using the
Medical Dictionary for Regulatory Activities. Treatment-emergent AEs are AEs with onset
during the intervention phase or that are a consequence of a pre-existing condition that has

worsened since baseline. All reported AEs will be included in the analysis. Adverse events will
be summarized by system organ class, preferred term, worst grade experienced by the
participant, and by dose level. For each AE, the percentage of participants who experience at
least 1 occurrence of the given event will be summarized by intervention group. In addition,
comparisons between intervention groups will be provided if appropriate.
Summaries, listings, datasets, or participant narratives may be provided, as appropriate, for those
participants who die, who discontinue intervention due to an AE, or who experience a severe or a
SAE.
Parameters with predefined NCI-CTCAE toxicity grades will be summarized.
Clinical Laboratory Tests
Laboratory data will be summarized by type of laboratory test. Reference ranges and markedly
abnormal results (specified in the Statistical Analysis Plan) will be used in the summary of
laboratory data. Descriptive statistics will be calculated for selected laboratory analytes at
baseline and for observed values and changes from baseline at each scheduled time point.
Changes from baseline results will be presented in pre- versus post-intervention cross-tabulations
(with classes for below, within, and above normal ranges). A listing of participants with any
laboratory results outside the reference ranges will be provided. A listing of participants with any
markedly abnormal laboratory results will also be provided.
Electrocardiogram
Electrocardiogram data will be summarized on categories of normal, abnormal, either clinically
significant or not clinically significant.
Vital Sign
Descriptive statistics of temperature, pulse/heart rate, respiratory rate, and blood pressure
(systolic and diastolic) values and changes from baseline will be summarized at each scheduled
time point. The percentage of participants with values beyond clinically important limits will be
summarized.
Physical Examination
Descriptive statistics of changes from baseline will be summarized at each scheduled time point.
9.4.3. 
Other Analyses
Pharmacokinetic Analyses
All concentrations below the lowest quantifiable concentration or missing data will be labeled as
such in the concentration database. Concentrations below the lowest quantifiable concentration
will be treated as zero in the summary statistics.

Approved, Date: 3 June 2021
Descriptive statistics will be used to summarize daratumumab serum concentrations at each
sampling time point.
If sufficient data are available, then population PK analysis of serum concentration-time data of
daratumumab may be performed using nonlinear mixed effects modeling and may include data
from other studies. If the population PK analysis is conducted, details will be given in a
population PK analysis plan and the results of the analysis will be presented in a separate report.
Biomarkers Analyses
Baseline bone marrow aspirate samples will be evaluated by a NGS assay to establish the
myeloma clone (calibration) and for MRD monitoring. In this study, bone marrow samples will
be collected when a bone marrow aspirate is performed at screening and at the subsequent
timepoints outlined in the Schedule of Activities (Table 1 and Table 3). Whole blood sample will
be collected from participants as outlined in the Schedule of Activities (Table 1 to Table 3) and
processed to plasma and PBMCs.
Any biomarker measurements will be listed, tabulated, and where appropriate, plotted. Statistical
analyses will be done to aid in the understanding of the results. Results of biomarker may be
presented in a separate report.
Immunogenicity Analyses
The prevalence and incidence of anti-daratumumab antibodies will be summarized for all
participants who have at least 1 anti-daratumumab antibody value. The prevalence and incidence
of anti-rHuPH20 antibodies will be summarized for all participants who receive a dose of
daratumumab and have at least 1 sample for detection of anti-rHuPH20 antibodies obtained after
the first dose of daratumumab. A listing of participants who are positive for anti-daratumumab or
anti-rHuPH20 antibodies will be provided.
Pharmacokinetic/Pharmacodynamic Analyses
PK/pharmacodynamic modeling may be performed, including exploring the relationship between
serum concentrations of daratumumab and endpoints of clinical efficacy or safety. Details and
results of any analysis performed will be presented in a separate report.
Medical Resource Utilization Analyses
Medical resource utilization will be descriptively summarized by intervention group.
9.5. 
Interim Analysis
An interim futility analysis will be conducted after 40% of participants are enrolled and treated
for 6 months.  The rate of VGPR or better will be the primary endpoint for the futility analysis. If
the observed rate of VGPR or better in the DKd group is no higher than the rate in the Kd group,
then the null hypothesis (no treatment difference in rate of VGPR or better) will be accepted, and
the study will be terminated. This criterion only serves as a statistical guidance. Assuming the
rate of VGPR or better in the Kd group is 45%, the probability of early termination is at least

53% if in fact the rate in the DKd group is no higher than 45%, and the probability of termination
is no greater than 8% if in fact the rate of VGPR or better in the DKd group is at least 60%.
9.5.1. 
Data Review Committee
An internal Data Review Committee (DRC) will be established as noted in Committees Structure
in Appendix 4.  The scheduled DRC  meetings will take place when the first 60 participants
complete 1 cycle of the study treatment, and every 6 months thereafter. In addition, there will be
a scheduled meeting to review the results of the interim futility analysis.

10.2. Appendix 2: Anticipated Events
Anticipated Event
An anticipated event is an AE (serious or non-serious) that commonly occurs as a consequence
of the underlying disease or condition under investigation (disease related) or background
regimen.
For the purposes of this study the following events will be considered anticipated events:
Bleeding
Bone diseases
Hypercalcemia
Hyperuricemia
Hyperviscosity syndrome
Infection
Renal failure or insufficiency
Reporting of Anticipated Events
All AEs will be recorded in the eCRF regardless of whether considered to be anticipated events
and will be reported to the sponsor as described under All AEs in Appendix 5. Any anticipated
event that meets SAE criteria will be reported to the sponsor as described in Section 8.3.1, Time
Period and Frequency for Collecting Adverse Event and Serious Adverse Event Information.
Each anticipated event will be assessed by the investigator at the individual case level and if
considered to be drug-related will undergo expedited reporting (if appropriate) as per applicable
clinical trial legislation to Health Authorities and IRBs/IECs. If an anticipated event is
considered disease-related or not related to study drug the event will be exempt from expedited
reporting.
To meet U.S. regulatory clinical trial legislation, the sponsor will perform aggregate review of
anticipated events as outlined below and, if determined to be drug-related, will implement
expedited reporting of these events to Health Authorities and IRBs/IECs. If an interim analysis
of trial results leads to an unblinded, aggregate review of safety data by the study team, the
sponsor may terminate the review of pre-specified anticipated events outlined above.
Safety Assessment Committee (SAC)
A SAC will be established to perform reviews of pre-specified anticipated events at an aggregate
level. The SAC is a safety committee within the sponsor’s organization that is independent of the
sponsor’s study team. The SAC will meet to aid in the recommendation to the sponsor’s study
team as to whether there is a reasonable possibility that an anticipated event is related to the
study intervention based on a review of the aggregate data by arm.

10.4. Appendix 4: Regulatory, Ethical, and Study Oversight Considerations
REGULATORY AND ETHICAL CONSIDERATIONS
Investigator Responsibilities
The investigator is responsible for ensuring that the study is performed in accordance with the
protocol, current ICH guidelines on Good Clinical Practice (GCP), and applicable regulatory and
country-specific requirements.
Good Clinical Practice is an international ethical and scientific quality standard for designing,
conducting, recording, and reporting studies that involve the participation of human participants.
Compliance with this standard provides public assurance that the rights, safety, and well-being of
study participants are protected, consistent with the principles that originated in the Declaration
of Helsinki, and that the study data are credible.
Protocol Amendments
Neither the investigator nor the sponsor will modify this protocol without a formal amendment
by the sponsor. All protocol amendments must be issued by the sponsor and signed and dated by
the investigator. Protocol amendments must not be implemented without prior IEC/IRB
approval, or when the relevant competent authority has raised any grounds for non-acceptance,
except when necessary  to eliminate immediate hazards to the participants, in which case the
amendment must be promptly submitted to the IEC/IRB and relevant competent authority.
Documentation of amendment approval by the investigator and IEC/IRB must be provided to the
sponsor. When the change(s) involve only logistic or administrative aspects of the study, the
IEC/IRB (where required) only needs to be notified.
During the course of the study, in situations where a departure from the protocol is unavoidable,
the investigator or other physician in attendance will contact the appropriate sponsor
representative listed in the Contact Information page(s), which will be provided as a separate
document. Except in emergency situations, this contact should be made before implementing any
departure from the protocol. In all cases, contact with the sponsor must be made as soon as
possible to discuss the situation and agree on an appropriate course of action. The data recorded
in the eCRF and source documents will reflect any departure from the protocol, and the source
documents will describe this departure and the circumstances requiring it.
Regulatory Approval/Notification
This protocol and any amendment(s) must be submitted to the appropriate regulatory authorities

INFORMED CONSENT PROCESS
Each participant must give written consent according to local requirements after the nature of the
study has been fully explained. The ICF(s) must be signed before performance of any study-
related activity. The ICF(s) that is/are used must be approved by both the sponsor and by the
reviewing IEC/IRB and be in a language that the participant can read and understand. The
informed consent should be in accordance with principles that originated in the Declaration of
Helsinki, current ICH and GCP guidelines, applicable regulatory requirements, and sponsor
policy.
Before enrollment in the study, the investigator or an authorized member of the study-site
personnel must explain to potential participants the aims, methods, reasonably anticipated
benefits, and potential hazards of the study, and any discomfort participation in the study may
entail. Participants will be informed that their participation is voluntary and that they may
withdraw consent to participate at any time. They will be informed that choosing not to
participate will not affect the care the participant will receive for the treatment of his or her
disease. Participants will be told that alternative treatments are available if they refuse to take
part and that such refusal will not prejudice future treatment. Finally, they will be told that the
investigator will maintain a participant identification register for the purposes of long-term
follow up if needed and that their records may be accessed by health authorities and authorized
sponsor personnel without violating the confidentiality of the participant, to the extent permitted
by the applicable law(s) or regulations. By signing the ICF the participant is authorizing such
access, which includes permission to obtain information about his or her survival status. It also
denotes that the participant agrees to allow his or her study physician to recontact the participant
for the purpose of obtaining consent for additional safety evaluations, and subsequent disease-
related treatments, if needed.
The participant will be given sufficient time to read the ICF and the opportunity to ask questions.
After this explanation and before entry into the study, consent should be appropriately recorded
by means of the participant's personally dated signature. After having obtained the consent, a
copy of the ICF must be given to the participant.
Participants who are rescreened are required to sign a new ICF
Where local regulations require, a separate ICF may be used for the required DNA component of
the study.
If the participant is unable to read or write, an impartial witness should be present for the entire
informed consent process (which includes reading and explaining all written information) and
should personally date and sign the ICF after the oral consent of the participant is obtained.

When prior consent of the participant is not possible, enrollment procedures should be described
in the protocol with documented approval/favorable opinion by the IEC/IRB to protect the rights,
safety, and well-being of the participant and to ensure compliance with applicable regulatory
requirements. The participant must be informed about the study as soon as possible and give
consent to continue.
DATA PROTECTION
Privacy of Personal Data
The collection and processing of personal data from participants enrolled in this study will be
limited to those data that are necessary to fulfill the objectives of the study.
These data must be collected and processed with adequate precautions to ensure confidentiality
and compliance with applicable data privacy protection laws and regulations. Appropriate
technical and organizational measures to protect the personal data against unauthorized
disclosures or access, accidental or unlawful destruction, or accidental loss or alteration must be
put in place. Sponsor personnel whose responsibilities require access to personal data agree to
keep the identity of participants confidential.
The informed consent obtained from the participant includes explicit consent for the processing
of personal data and for the investigator/institution to allow direct access to his or her original
medical records (source data/documents) for study-related monitoring, audit, IEC/IRB review,
and regulatory inspection. This consent also addresses the transfer of the data to other entities
and to other countries.
The participant has the right to request through the investigator access to his or her personal data
and the right to request rectification of any data that are not correct or complete. Reasonable
steps will be taken to respond to such a request, taking into consideration the nature of the
request, the conditions of the study, and the applicable laws and regulations.
Exploratory PK and immunogenicity research is not conducted under standards appropriate for
the return of data to participants. In addition, the sponsor cannot make decisions as to the
significance of any findings resulting from exploratory research. Therefore, exploratory research
data will not be returned to participants or investigators, unless required by law or local
regulations. Privacy and confidentiality of data generated in the future on stored samples will be
protected by the same standards applicable to all other clinical data.
DATA REVIEW COMMITTEE (DRC) STRUCTURE
A DRC will be established to ensure the continuing safety of the participants enrolled in this
study and to review safety results at the planned interim analyses. Committee membership
responsibilities, authorities, and procedures will be documented in its charter.

PUBLICATION POLICY/DISSEMINATION OF CLINICAL STUDY DATA
All information, including but not limited to information regarding daratumumab or the sponsor's
operations (eg, patent application, formulas, manufacturing processes, basic scientific data, prior
clinical data, formulation information) supplied by the sponsor to the investigator and not
previously published, and any data, including biomarker research data, generated as a result of
this study, are considered confidential and remain the sole property of the sponsor. The
investigator agrees to maintain this information in confidence and use this information only to
accomplish this study and will not use it for other purposes without the sponsor's prior written
consent.
The investigator understands that the information developed in the study will be used by the
sponsor in connection with the continued development of daratumumab, and thus may be
disclosed as required to other clinical investigators or regulatory agencies. To permit the
information derived from the clinical studies to be used, the investigator is obligated to provide
the sponsor with all data obtained in the study.
The results of the study will be reported in a CSR generated by the sponsor and will contain data
from all study sites that participated in the study as per protocol. Recruitment performance or
specific expertise related to the nature and the key assessment parameters of the study will be
used to determine a coordinating investigator for the study. Results of biomarker analyses
performed after the CSR has been issued will be reported in a separate report and will not require
a revision of the CSR.
Study participant identifiers will not be used in publication of results. Any work created in
connection with performance of the study and contained in the data that can benefit from
copyright protection (except any publication by the investigator as provided for below) shall be
the property of the sponsor as author and owner of copyright in such work.
Consistent with Good Publication Practices and International Committee of Medical Journal
Editors (ICMJE) guidelines, the sponsor shall have the right to publish such primary
(multicenter) data and information without approval from the investigator. The investigator has
the right to publish study site-specific data after the primary data are published. If an investigator
wishes to publish information from the study, a copy of the manuscript must be provided to the
sponsor for review at least 60 days before submission for publication or presentation. Expedited
reviews will be arranged for abstracts, poster presentations, or other materials. If requested by
the sponsor in writing, the investigator will withhold such publication for up to an additional
60 days to allow for filing of a patent application. In the event that issues arise regarding
scientific integrity or regulatory compliance, the sponsor will review these issues with the
investigator. The sponsor will not mandate modifications to scientific content and does not have
the right to suppress information. For multicenter study designs and substudy approaches,
secondary results generally should not be published before the primary endpoints of a study have
been published. Similarly, investigators will recognize the integrity of a multicenter study by not
submitting for publication data derived from the individual study site until the combined results
from the completed study have been submitted for publication, within 18 months after the study

end date, or the sponsor confirms there will be no multicenter study publication. Authorship of
publications resulting from this study will be based on the guidelines on authorship, such as
those described in the ICMJE Recommendations for the Conduct, Reporting, Editing and
Publication of Scholarly Work  in Medical Journals, which state that the named authors must
have made a significant contribution to the conception or design of the work; or the acquisition,
analysis, or interpretation of the data for the work; and drafted the work or revised it critically for
important intellectual content; and given final approval of the version to be published; and
agreed to be accountable for all aspects of the work in ensuring that questions related to the
accuracy or integrity of any part of the work are appropriately investigated and resolved.
Registration of Clinical Studies and Disclosure of Results
The sponsor will register and disclose the existence of and the results of clinical studies as
required by law.
DATA QUALITY ASSURANCE
Data Quality Assurance/Quality Control
Steps to be taken to ensure the accuracy and reliability of data include the selection of qualified
investigators and appropriate study sites, review of protocol procedures with the investigator and
study-site personnel before the study, periodic monitoring visits by the sponsor, and direct
transmission of clinical laboratory data from a central laboratory into the sponsor's data base.
Written instructions will be provided for collection, handling, storage, and shipment of samples.
Guidelines for eCRF completion will be provided and reviewed with study-site personnel before
the start of the study.
The sponsor will review eCRF for accuracy and completeness during on-site monitoring visits
and after transmission to the sponsor; any discrepancies will be resolved with the investigator or
designee, as appropriate. After upload of the data into the study database they will be verified for
accuracy and consistency with the data sources.
CASE REPORT FORM COMPLETION
Case report forms are prepared and provided by the sponsor for each participant in electronic
format. All data relating to the study must be recorded in eCRF. All eCRF entries, corrections,
and alterations must be made by the investigator or authorized study-site personnel. The
investigator must verify that all data entries in the eCRF are accurate and correct.
The study data will be transcribed by study-site personnel from the source documents onto an
eCRF, if applicable. Study-specific data will be transmitted in a secure manner to the sponsor.
Worksheets may be used for the capture of some data to facilitate completion of the eCRF. Any
such worksheets will become part of the participant's source documents. Data must be entered

into eCRF in English. The eCRF must be completed as soon as possible after a participant visit
and the forms should be available for review at the next scheduled monitoring visit.
If necessary, queries will be generated in the electronic data capture (eDC) tool. If corrections to
an eCRF  are needed after the initial entry into the eCRF, this can be done in either of the
following ways:
 Investigator and study-site personnel can make corrections in the eDC tool at their own
initiative or as a response to an auto query (generated by the eDC tool).
 Sponsor or sponsor delegate can generate a query for resolution by the investigator and
study-site personnel.
SOURCE DOCUMENTS
At a minimum, source documents consistent in the type and level of detail with that commonly
recorded at the study site as a basis for standard medical care must be available for the following:
participant identification, eligibility, and study identification; study discussion and date of signed
informed consent; dates of visits; results of safety and efficacy parameters as required by the
protocol; record of all AEs and follow-up of AEs; concomitant medication; intervention
receipt/dispensing/return records; study intervention administration information; and date of
study completion and reason for early discontinuation of study intervention or withdrawal from
the study, if applicable.
The author of an entry in the source documents should be identifiable.
Specific details required as source data for the study and source data collection methods will be
reviewed with the investigator before the study and will be described in the monitoring
guidelines (or other equivalent document).
The following data will be recorded directly into the eCRF and will be considered source data
(ie, must be recorded in patient medical records):
Race
Blood pressure and pulse/heart rate
Height and weight
Details of physical examination
ECOG, medical resource utilization data
The minimum source documentation requirements for Section 5.1, Inclusion Criteria and
Section 5.2, Exclusion Criteria that specify a need for documented medical history are as
follows:
 Referral letter from treating physician or

Approved, Date: 3 June 2021
 Complete history of medical notes at the site
 Discharge summaries
Inclusion and exclusion criteria not requiring documented medical history must be verified at a
minimum by participant interview or other protocol required assessment (eg, physical
examination, laboratory assessment) and documented in the source documents.
An eSource system may be utilized, which contains data traditionally maintained in a hospital or
clinic record to document medical care (eg, electronic source documents) as well as the clinical
study-specific data fields as determined by the protocol. This data is electronically extracted for
use by the sponsor. If eSource is utilized, references made to the eCRF in the protocol include
the eSource system but information collected through eSource may not be limited to that found
in the eCRF.
MONITORING
The sponsor will use a combination of monitoring techniques, central, remote, and on-site
monitoring to monitor this study.
The sponsor will perform on-site monitoring visits as frequently as necessary. The monitor will
record dates of the visits in a study site visit log that will be kept at the study site. The first post-
initiation visit will be made as soon as possible after enrollment has begun. At these visits, the
monitor will compare data entered into the eCRF with the source documents
(eg, hospital/clinic/physician’s office medical records); a sample may be reviewed. The nature
and location of all source documents will be identified to ensure that all sources of original data
required to complete the eCRF are known to the sponsor and study-site personnel and are
accessible for verification by the sponsor study-site contact. If electronic records are maintained
at the study site, the method of verification must be discussed with the study-site personnel.
Direct access to source documents (medical records) must be allowed for the purpose of
verifying that the recorded data are consistent with the original source data. Findings from this
review will be discussed with the study-site personnel. The sponsor expects that, during
monitoring visits, the relevant study-site personnel will be available, the source documents will
be accessible, and a suitable environment will be provided for review of study-related
documents. The monitor will meet with the investigator on a regular basis during the study to
provide feedback on the study conduct.
In addition to on-site monitoring visits, remote contacts can occur. It is expected that during
these remote contacts, study-site personnel will be available to provide an update on the progress
of the study at the site.
Central monitoring will take place for data identified by the sponsor as requiring central review.

ON-SITE AUDITS
Representatives of the sponsor's clinical quality assurance department may visit the study site at
any time during or after completion of the study to conduct an audit of the study in compliance
with regulatory guidelines and company policy. These audits will require access to all study
records, including source documents, for inspection. Participant privacy must, however, be
respected. The investigator and study-site personnel are responsible for being present and
available for consultation during routinely scheduled study-site audit visits conducted by the
sponsor or its designees.
Similar auditing procedures may also be conducted by agents of any regulatory body, either as
part of a national GCP compliance program or to review the results of this study in support of a
regulatory submission. The investigator should immediately notify the sponsor if he or she has
been contacted by a regulatory agency concerning an upcoming inspection.
RECORD RETENTION
In compliance with the ICH/GCP guidelines, the investigator/institution will maintain all eCRF
and all source documents that support the data collected from each participant, as well as all
study documents as specified in ICH/GCP Section 8, Essential Documents for the Conduct of a
Clinical Trial, and all study documents as specified by the applicable regulatory requirement(s).
The investigator/institution will take measures to prevent accidental or premature destruction of
these documents.
Essential documents must be retained until at least 2 years after the last approval of a marketing
application in an ICH region and until there are no pending or contemplated marketing
applications in an ICH region  or until at least 2 years have elapsed since the formal
discontinuation of clinical development of the investigational product. These documents will be
retained for a longer period if required by the applicable regulatory requirements or by an
agreement with the sponsor. It is the responsibility of the sponsor to inform the
investigator/institution as to when these documents no longer need to be retained.
If the responsible investigator retires, relocates, or for other reasons withdraws from the
responsibility of keeping the study records, custody must be transferred to a person who will
accept the responsibility. The sponsor must be notified in writing of the name and address of the
new custodian. Under no circumstance shall the investigator relocate or dispose of any study
documents before having obtained written approval from the sponsor.
If it becomes necessary for the sponsor or the appropriate regulatory authority to review any
documentation relating to this study, the investigator/institution must permit access to such
reports.

STUDY AND SITE CLOSURE
Study Termination
The sponsor reserves the right to close the study site or terminate the study at any time for any
reason at the sole discretion of the sponsor. Study sites will be closed upon study completion. A
study site is considered closed when all required documents and study supplies have been
collected and a study-site closure visit has been performed.
The investigator may initiate study-site closure at any time, provided there is reasonable cause
and sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a study site by the sponsor or investigator may include but are
not limited to:
 Failure of the investigator to comply with the protocol, the requirements of the IEC/IRB or
local health authorities, the sponsor's procedures, or GCP guidelines
 Inadequate recruitment of participants by the investigator
 Discontinuation of further study intervention development

10.5. Appendix 5: Adverse Events: Definitions and Procedures for Recording,
Evaluating, Follow-up, and Reporting
ADVERSE EVENT DEFINITIONS AND CLASSIFICATIONS
Adverse Event
An AE is any untoward medical occurrence in a clinical study participant administered a
medicinal (investigational or non-investigational) product. An AE does not necessarily have a
causal relationship with the intervention. An AE can therefore be any unfavorable and
unintended sign (including an abnormal finding), symptom, or disease temporally associated
with the use of a medicinal (investigational or non-investigational) product, whether or not
related to that medicinal (investigational or non-investigational) product. (Definition per
International Conference on Harmonisation [ICH])
This includes any occurrence that is new in onset or aggravated in severity or frequency from the
baseline condition, or abnormal results of diagnostic procedures, including laboratory test
abnormalities.
Note: The sponsor collects AEs starting with the signing of the ICF (refer to All AEs under
Section 8.3.1, Time Period and Frequency for Collecting Adverse Events and Serious Adverse
Events Information, for time of last adverse event recording).
Serious Adverse Event
An SAE event based on ICH and EU Guidelines on Pharmacovigilance for Medicinal Products
for Human Use is any untoward medical occurrence that at any dose:
Results in death
Is life-threatening
(The participant was at risk of death at the time of the event. It does not refer to an event that
hypothetically might have caused death if it were more severe.)
Requires inpatient hospitalization or prolongation of existing hospitalization
Results in persistent or significant disability/incapacity
Is a congenital anomaly/birth defect
Is a suspected transmission of any infectious agent via a medicinal product
Is Medically Important*
*Medical and scientific judgment should be exercised in deciding whether expedited reporting is
also appropriate in other situations, such as important medical events that may not be
immediately life threatening or result in death or hospitalization but may jeopardize the
participant or may require intervention to prevent one of the other outcomes listed in the
definition above. These should usually be considered serious.

Clinical Protocol 54767414MMY2065 Amendment 2
CONFIDENTIAL –FOIA Exemptions Apply in U.S. 
100
Approved, Date: 3 June 2021
If a serious and unexpected AE occurs for which there is evidence suggesting a causal
relationship between the study intervention and the event (eg, death from anaphylaxis), the event
must be reported as a serious and unexpected suspected adverse reaction even if it is a
component of the study endpoint (eg, all-cause mortality).
Expected progression of disease should not be considered an AE (or SAE). However, if
determined by the investigator to be more likely related to the study intervention than the
underlying disease, the clinical signs or symptoms of progression and the possibility that the
study intervention is enhancing disease progression, should be reported per the usual reporting
requirements
Unlisted (Unexpected) Adverse Event/Reference Safety Information
An AE is considered unlisted if the nature or severity is not consistent with the applicable
product reference safety information. For daratumumab, the expectedness of an AE will be
determined by whether or not it is listed in the IB. For Kd, the expectedness of an AE will be
determined by whether or not it is listed in the package insert/summary of product
characteristics.
Adverse Event Associated With the Use of the Intervention
An AE is considered associated with the use of the intervention if the attribution is possible,
probable, or very likely by the definitions listed below (see Attribution Definitions).
ATTRIBUTION DEFINITIONS
Not Related
An AE that is not related to the use of the study intervention.
The following attributions are considered “Not Related”:
Not Related
An adverse event that is not related to the use of the intervention.
Doubtful
An adverse event for which an alternative explanation is more likely, eg, concomitant
drug(s), concomitant disease(s), or the relationship in time suggests that a causal
relationship is unlikely.
Related
An AE that is related to the use of the study intervention.

Clinical Protocol 54767414MMY2065 Amendment 2
CONFIDENTIAL –FOIA Exemptions Apply in U.S. 
101
Approved, Date: 3 June 2021
The following attributions are considered “Related”:
Possible
An adverse event that might be due to the use of the intervention. An alternative
explanation, eg, concomitant drug(s), concomitant disease(s), is inconclusive. The
relationship in time is reasonable; therefore, the causal relationship cannot be excluded.
Probable
An adverse event that might be due to the use of the intervention. The relationship in time
is suggestive (eg, confirmed by dechallenge). An alternative explanation is less likely, eg,
concomitant drug(s), concomitant disease(s).
Very Likely
An adverse event that is listed as a possible adverse reaction and cannot be reasonably
explained by an alternative explanation, eg, concomitant drug(s), concomitant disease(s).
The relationship in time is very suggestive (eg, it is confirmed by dechallenge and
rechallenge).
SEVERITY CRITERIA
The severity assessment for an AE or SAE should be completed using the NCI CTCAE
Version 4.03.
SPECIAL REPORTING SITUATIONS
Safety events of interest on a sponsor study intervention in an interventional study that may
require expedited reporting or safety evaluation include, but are not limited to:
Overdose of a sponsor study intervention
Suspected abuse/misuse of a sponsor study intervention
Accidental or occupational exposure to a sponsor study intervention
Medication error involving a sponsor product (with or without participant/patient exposure to the
sponsor study intervention, eg, name confusion)
Exposure to a sponsor study intervention from breastfeeding
Special reporting situations should be recorded in the eCRF. Any special reporting situation that
meets the criteria of an SAE should be recorded on the SAE page of the eCRF.

PROCEDURES
All Adverse Events
All AEs, regardless of seriousness, severity, or presumed relationship to study intervention, must
be recorded using medical terminology in the source document and the eCRF. Whenever
possible, diagnoses should be given when signs and symptoms are due to a common etiology
(eg, cough, runny nose, sneezing, sore throat, and head congestion should be reported as "upper
respiratory infection"). Investigators must record in the eCRF their opinion concerning the
relationship of the AE to study therapy. All measures required for AE management must be
recorded in the source document and reported according to sponsor instructions.
For all studies with an outpatient phase, including open-label studies, the participant must be
provided with a "wallet (study) card" and instructed to carry this card with them for the duration
of the study indicating the following:
Study number
Statement, in the local language(s), that the participant is participating in a clinical study
Investigator's name and 24-hour contact telephone number
Local sponsor's name and 24-hour contact telephone number (for medical staff only)
Site number
Participant number
Serious Adverse Events
All SAEs that have not resolved by the end of the study, or that have not resolved upon
discontinuation of the participant's participation in the study, must be followed until any of the
following occurs:
The event resolves
The event stabilizes
The event returns to baseline, if a baseline value/status is available
The event can be attributed to agents other than the study intervention or to factors unrelated to
study conduct
It becomes unlikely that any additional information can be obtained (participant or health care
practitioner refusal to provide additional information, lost to follow-up after demonstration of
due diligence with follow-up efforts)
Suspected transmission of an infectious agent by a medicinal product will be reported as an SAE.
Any event requiring hospitalization (or prolongation of hospitalization) that occurs during the
course of a participant's participation in a study must be reported as an SAE, except
hospitalizations for the following:

Approved, Date: 3 June 2021
If the participant has not experienced a significant medical event but is hospitalized overnight
only for observation following injection of study intervention, then the hospitalization should not
be reported as a SAE.
Hospitalizations not intended to treat an acute illness or AE (eg, social reasons such as pending
placement in long-term care facility)
Surgery or procedure planned before entry into the study (must be documented in the eCRF).
Note: Hospitalizations that were planned before the signing of the ICF, and where the underlying
condition for which the hospitalization was planned has not worsened, will not be considered
SAEs. Any AE that results in a prolongation of the originally planned hospitalization is to be
reported as a new SAE.
For convenience the investigator may choose to hospitalize the participant for the duration of the
intervention period.
Disease progression should not be recorded as an AE or SAE term; instead, signs and symptoms
of clinical sequelae resulting from disease progression/lack of efficacy will be reported if they
fulfill the SAE definition (refer to Adverse Event Definitions and Classifications in Appendix 5).
CONTACTING SPONSOR REGARDING SAFETY
The names (and corresponding telephone numbers) of the individuals who should be contacted
regarding safety issues or questions regarding the study are listed in the Contact Information
page(s), which will be provided as a separate document.
PRODUCT QUALITY COMPLAINT HANDLING
A product quality complaint (PQC) is defined as any suspicion of a product defect related to
manufacturing, labeling, or packaging, ie, any dissatisfaction relative to the identity, quality,
durability, or reliability of a product, including its labeling or package integrity. A PQC may have
an impact on the safety and efficacy of the product. Timely, accurate, and complete reporting and
analysis of PQC information from studies are crucial for the protection of participants,
investigators, and the sponsor, and are mandated by regulatory agencies worldwide. The sponsor
has established procedures in conformity with regulatory requirements worldwide to ensure
appropriate reporting of PQC information; all studies conducted by the sponsor or its affiliates
will be conducted in accordance with those procedures.
Procedures
All initial PQCs must be reported to the sponsor by the study-site personnel within 24 hours after
being made aware of the event.
If the defect is combined with an SAE, the study-site personnel must report the PQC to the
sponsor according to the SAE reporting timelines (refer to Section 8.3.1, Time Period and
Frequency for Collecting Adverse Event and Serious Adverse Event Information). A sample of
the suspected product should be maintained for further investigation if requested by the sponsor.

10.6. Appendix 6: Contraceptive and Barrier Guidance and Collection of
Pregnancy Information
Participants must follow contraceptive measures as outlined in Section 5.1, Inclusion Criteria.
Pregnancy information will be collected and reported as noted in Section 8.3.4 and Appendix 5.
Female participants:
Women of childbearing potential must commit to either abstain continuously from heterosexual
sexual intercourse or to use 2 methods of reliable birth control simultaneously. This includes one
highly effective form of contraception (tubal ligation, intrauterine device, hormonal [birth
control pills, injections, hormonal patches, vaginal rings or implants] or partner's vasectomy) and
one additional effective contraceptive method (male latex or synthetic condom, diaphragm, or
cervical cap). A reduction in the effectiveness of oral contraceptives during carfilzomib
treatment cannot be excluded. In addition, because of the increased risk of venous
thromboembolic events associated with carfilzomib, women should avoid the use of hormonal
contraceptives that are associated with a risk of thrombosis during treatment with carfilzomib.
Women of childbearing potential who are using oral contraceptives or a hormonal method of
contraception that is associated with a risk of thrombosis should switch to an alternative method
of highly effective contraception. Contraception must begin with study treatment initiation and
continue for 3 months after discontinuing study treatment. Reliable contraception is indicated
even where there has been a history of infertility, unless due to hysterectomy.
Male participants:
Male participants who are sexually active with women of childbearing potential or with pregnant
women must always use a latex or synthetic condom during the study and for 3 months after
discontinuing study treatment (even after a successful vasectomy).
Definitions
Woman of Childbearing Potential
A woman is considered fertile following menarche and until becoming postmenopausal unless
permanently sterile (see below).
Woman Not of Childbearing Potential
premenarchal
A premenarchal state is one in which menarche has not yet occurred.
postmenopausal
A postmenopausal state is defined as no menses for 12 months without an alternative medical
cause. A high follicle stimulating hormone level (>40 IU/L or mIU/mL) in the postmenopausal
range may be used to confirm a postmenopausal state in women not using hormonal
contraception or hormonal replacement therapy (HRT), however in the absence of 12 months of
amenorrhea, a single follicle stimulating hormone measurement is insufficient.

Approved, Date: 3 June 2021
If there is a question about menopausal status in women on HRT, the woman will be required to
use one of the non-estrogen-containing hormonal highly effective contraceptive methods if she
wishes to continue HRT during the study.
permanently sterile
Permanent sterilization methods include hysterectomy, bilateral salpingectomy, bilateral tubal
occlusion/ligation procedures, and bilateral oophorectomy.
Note: If the childbearing potential changes after start of the study (eg, a premenarchal woman
experiences menarche) or the risk of pregnancy changes (eg, a woman who is not heterosexually
active becomes active), a woman must begin a highly effective method of contraception, as
described throughout the inclusion criteria.
If reproductive status is questionable, additional evaluation should be considered.

Intrauterine device
Intrauterine hormone-releasing system
Bilateral tubal occlusion
Vasectomized partner
(Vasectomized partner is ahighly effective contraceptive method provided that the partner is the
sole sexual partner of the woman of childbearing potential and the absence of sperm has been
confirmed. If not, additional highly effective method of contraception should be used.
Spermatogenesis cycle is approximately 74 days.)
USER DEPENDENT
Highly Effective Methods That Are User Dependent Failure rate of <1% per year when used
consistently and correctly.

Sexual abstinence
(Sexual abstinence is considered a highly effective method only if defined as refraining from
heterosexual intercourse during the entire period of risk associated with the study intervention.
The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study
and the preferred and usual lifestyle of the participant.)
NOT ALLOWED AS SOLE METHOD OF CONTRACEPTION DURING THE STUDY (not
considered to be highly effective - failure rate of >1% per year)
Progestogen-only oral hormonal contraception where inhibition of ovulation is not the primary mode
of action.
Male or female condom with or without spermicidec
Cap, diaphragm, or sponge with spermicide
A combination of male condom with either cap, diaphragm, or sponge with spermicide (double-barrier
methods)c
Periodic abstinence (calendar, symptothermal, post-ovulation methods)
Withdrawal (coitus-interruptus)
Spermicides alone
Lactational amenorrhea method
a) Typical use failure rates may differ from those when used consistently and correctly. Use should be
consistent with local regulations regarding the use of contraceptive methods for participants in
clinical studies.
b) Hormonal contraception may be susceptible to interaction with the study intervention, which may
reduce the efficacy of the contraceptive method. In addition, consider if the hormonal contraception
may interact with the study intervention.
c) Male condom and female condom should not be used together (due to risk of failure with friction).

10.15. Appendix 15: Interpretation of the SEBIA Hydrashift 2/4 Daratumumab
Immunofixation Electrophoresis Interference Test
Background: Clinical response assessment in myeloma relies on serum protein electrophoresis
(SPEP) and immunofixation electrophoresis (IFE). As daratumumab is a monoclonal IgG kappa
antibody, the SPEP and IFE can be positive for daratumumab at the serum levels anticipated
during this protocol.
Implementation: To mitigate this interference, the sponsor will use the SEBIA Hydrashift 2/4
Daratumumab IFE Interference test. Samples will be sent automatically to the central laboratory
if daratumumab interference is suspected.
Interpretation of results: The results will be available to the investigator via the central
laboratory interface and will be reported as follows:
DARAHydra Impress1:  result defined as “DARA detected”, “DARA not detected”, OR “DARA
indeterminate”
DARAHydra Impress2:  result defined as “M-protein not detected” OR the specific protein
detected (ie, “IgG,k” or “IgA”)
DARAHydra Impress3: result defined as “M-protein not detected” OR the specific protein
detected (ie, “IgG,k” or “IgA”)
If Impress1 result is “DARA detected” and Impress2 and 3 results are “M-protein not detected”,
the patient may be in complete response (CR) if the other criteria for CR (including negative
bone marrow aspirate/biopsy) are achieved.
If Impress1 result is “DARA not detected” or “DARA indeterminate”, the patient is still positive
for underlying (endogenous) monoclonal protein and Impress2 and 3 can inform as to the type of
endogenous protein still present.  Therefore, this patient is not in a complete response (CR),
because the CR response criteria requires a negative SPEP and serum IFE.
If Impress1 result is “DARA detected” but there is also protein present and reported by Impress2
or 3, the patient is still positive for underlying (endogenous) monoclonal protein and Impress2
and 3 can inform as to the type of endogenous protein still present.  Therefore, this patient is not
in a complete response (CR), because the CR response criteria requires a negative SPEP and
serum IFE.

The Protocol Amendment Summary of Changes Table for the current amendment is located directly
before the Table of Contents (TOC). A summary of previous amendment is provided below.
Amendment 1 (14 October 2019)
Overall Rationale for the Amendment: The overall rationale for the amendment is to include the
language clarifying the need for contraception for all participants to continue for 3 months after the end of
study treatment as well as the caution for women who are at high risk for thrombosis to use other means
of birth control other than hormonal birth control which carries the highest risk of thrombosis.

Physical
examination row;
8.2.1. Physical
Examination
Text was modified to clarify timing and description
of physical examination requirements.

Pregnancy test row
8. Study
Assessments and
Procedures
Decreased frequency of pregnancy testing to
Screening and Cycle 1 Day 1 during the study.
Added requirement for a pregnancy test at
End-of-Treatment (EOT) visit.
Decreased the total blood volume collected during
the study.
High frequency of pregnancy
testing is not necessary as none of
the drugs in this study are known to
be teratogenic.
Given drug half-lives a pregnancy
test will be required to confirm that
women of childbearing potential
are not pregnant 4 weeks post
therapy.
The decrease in the number of
pregnancy tests has resulted in less
blood being collected.
