Protocol Synopsis 
Title:  A Randomized, Open-label, Phase 3 Study Comparing Carfilzomib, Dexamethasone, and 
Daratumumab to Carfilzomib and Dexamethasone for the Treatment of Patients With Relapsed or 
Refractory Multiple Myeloma (CANDOR) 
Study Phase:  3 
Indication:  Relapsed or Refractory Multiple Myeloma 
Primary Objective:  The primary objective is to compare carfilzomib, dexamethasone, and 
daratumumab (KdD) to carfilzomib and dexamethasone (Kd) in terms of progression free survival 
(PFS) in patients with multiple myeloma who have relapsed after 1 to 3 prior therapies. 
Secondary Objective(s):  Key secondary objectives are to compare the following between the 
2 arms: 
 
Overall Response Rate (ORR; defined as the proportion of best overall response of stringent 
complete response [sCR], complete response [CR], very good partial response [VGPR], and 
partial response [PR]) 
 
rate of minimal residual disease negative-complete response (MRD[-]CR) in bone marrow 
aspirates at 12 months ( 4 weeks) as determined by Next-Generation sequencing (NGS) 
 
overall survival (OS) 
Additional secondary objectives are to compare the following between the 2 arms: 
 
safety and tolerability 
 
duration of response (DOR) 
 
time to next treatment  
 
time to progression (TTP) 
 
time to response 
 
persistence of MRD[-]CR 
 
complete response rate (CRR) 
 
MRD[-] rate 
 
quality of life 
Hypothesis:  The KdD regimen will provide significant improvement in PFS over the Kd regimen. 
Primary Endpoint:  PFS defined as time from randomization until disease progression or death 
from any cause.  Response and disease progression determined by a blinded Independent 
Review Committee (IRC). 
Secondary Endpoint(s):  Key secondary endpoints include: 
 
ORR:  defined as the proportion of best overall response of stringent complete response 
(sCR), complete response (CR), very good partial response (VGPR), and partial response 
(PR) by IRC 
 
MRD[-]CR rate, MRD[-]CR defined as achievement of CR by IRC per International Myeloma 
Working Group-Uniform Response Criteria (IMWG-URC) and MRD[-] status as assessed by 
NGS (at a 10-5 level, pending analytical validation) at 12 months

 
safety laboratory values, left ventricular ejection fraction (LVEF), forced expiratory volume in 
1 second (FEV1)/forced vital capacity (FVC) ratio, and vital signs at each scheduled 
assessment 
Study Design:  This is a phase 3 multicenter, open-label, randomized study in subjects with 
relapsed or refractory multiple myeloma (RRMM) who have received 1 to 3 prior therapies. 
Subjects will be randomized in a 2:1 ratio to 1 of 2 arms: 
 
Arm 1:  KdD 
 
Arm 2:  Kd 
Randomization will be performed using an interactive voice/web response system (IxRS) and 
subjects will be stratified based on the following criteria:  Original International Staging System 
(ISS) stage (variables:  albumin and beta 2 microglobulin; strata:  Stage 1 or 2 vs Stage 3) at 
screening, prior proteasome inhibitor exposure (yes vs no), number of prior lines of therapy 
(1 vs  2), and prior cluster differentiation antigen 38 (CD38) antibody therapy (yes vs no). 
Subjects will receive the study treatment determined by randomization
 or 
until confirmed disease progression, unacceptable toxicity, withdrawal of consent, or death 
(whichever occurs first).  No crossover between the treatment arms will be allowed.  All subjects 
will be assessed for multiple myeloma disease response according to the IMWG-URC using 
central laboratory test results every 28  7 days.  
 
 disease response assessments will be performed every 28  7 days until confirmed 
progressive disease (PD). 
Following progression or discontinuation of study drug(s), subjects will have 1 follow-up visit 
(30 days [ 3] after last dose of all study drug[s]).  After disease progression, data on survival 
status and subsequent antimyeloma therapy will be gathered at 
 
 
.   
Local serology testing for hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B 
core antibody will be performed at the next scheduled visit for all subjects that do not already 
have a known medical history of hepatitis B infection or who have not had testing conducted 
within the previous 12 weeks.  In addition, subjects with a known medical history of hepatitis B 
infection or who test positive for hepatitis B virus (HBV) serologies will be monitored closely for 
signs and symptoms of hepatitis B and will have local HBV deoxyribonucleic acid (DNA) testing 
performed at their next visit and then every 12 weeks ( 2 weeks) or more frequently if 
clinically indicated through follow-up Visit 1.  Subjects in arm 1 (KdD) will continue to be

monitored and tested for 6 months following the last dose of daratumumab.  A hepatitis 
specialist should be consulted for all subjects who test positive for HBV serology or HBV DNA to 
undergo full assessment and make decisions regarding HBV reactivation treatment and/or 
confirmation whether HBV reactivation is adequately controlled to resume study drugs.  
Subjects who have received Hepatitis B vaccination with only anti-HBs positivity and no clinical 
signs of hepatitis do not require HBV DNA monitoring. 
Sample Size:  Approximately 450 subjects will be enrolled (300 in arm 1 and 150 in arm 2).

Investigational Product 
Amgen Investigational Product Dosage and Administration: 
Carfilzomib will be administered as an intravenous (IV) infusion.  On days when more than 
1 investigational product is administered, the required order of administration is as follows:  
dexamethasone, pre-infusion medications for daratumumab, carfilzomib, daratumumab, and 
post-infusion medications for daratumumab. 
Carfilzomib will be dosed twice weekly over 30  5 minutes, on days 1, 2, 8, 9, 15, and 16 of each 
28-day cycle.  The administration may be within  2 days for each scheduled dose.  The dose will 
be 20 mg/m2 on cycle 1 days 1 and 2 and 56 mg/m2 beginning on cycle 1 day 8 and thereafter. 
Each subject’s first dose of carfilzomib will be calculated based upon baseline body surface area 
(BSA) using the Mosteller formula.  In subjects with BSA of greater than 2.2 m2, the dose should 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 6 of 140 
CONFIDENTIAL 
 
 
be capped based on a BSA of 2.2 m2.  The dose for each subject should not be revised unless 
the subject experiences a change in body weight of  20 in which case the BSA and dose 
should be recalculated.  The dose can also be modified in response to toxicity following the dose 
modification guideline tables. 
Non-Amgen Investigational Product Dosage and Administration: 
Daratumumab will be administered as an IV infusion.  On days 1 and 2 of cycle 1, daratumumab 
will be administered at 8 mg/kg in 500 mL normal saline each day.  The dose of 16 mg/kg in 
500 mL normal saline will be given once weekly as a single infusion for the remaining doses of 
the first 2 cycles (ie, days 8, 15, and 22 of cycle 1; and days 1, 8, 15, and 22 of cycle 2), then 
every 2 weeks for 4 cycles (cycles 3 to 6), and then every 4 weeks for the remaining cycles or 
until disease progression.  The administration may be within  2 days for each scheduled dose. 
Non-investigational Product 
Non-Amgen Non-investigational Product Dosage and Administration: 
Dexamethasone 40 mg will be taken orally (PO) or by IV infusion weekly.  The IV administration 
of dexamethasone must be given on cycle 1 days 1 and 2.  Dexamethasone IV or PO will be 
given on successive days at 20 mg each treatment day on weeks with carfilzomib and/or 
daratumumab infusions.  All subjects regardless of age will be required to receive 20 mg of 
dexamethasone on days 1 and 2 of cycle 1 (as a preinfusion medication for daratumumab 
infusion) followed by 20 mg of methylprednisolone or equivalent on the third day.  For 
Subjects 75 years of age or subjects whose weekly dexamethasone dose has been reduced to 
20 mg/week, 20 mg of dexamethasone will be given as a preinfusion medication for 
daratumumab infusion, followed by 8 mg of dexamethasone prior to carfilzomib infusion on 
days 9 and 16 of cycle 1.   
Starting with cycle 2, 20 mg dexamethasone must be given on days daratumumab is 
administered (without 8 mg dose on subsequent carfilzomib dosing day), otherwise the 20 mg 
dose can be split across carfilzomib dosing days. 
For days when dexamethasone is given in the absence of other IV infusion (neither carfilzomib 
nor daratumumab is scheduled), it may be given within  2 days for each scheduled dose.  
Dexamethasone will be administered at least 30 minutes (but no more than 4 hours) prior to 
carfilzomib and within 1 to 3 hours from the daratumumab dose. 
When carfilzomib is permanently discontinued, dexamethasone may be omitted on days when 
given in the absence of daratumumab based on their assessment of the subject’s steroid 
tolerance.  
For subjects in arm 1 on cycles 7 without previous infusion-related reaction (IRR), 
dexamethasone premedication may be decreased or omitted, if the subject cannot tolerate 20 mg 
of dexamethasone or equivalent. 
Procedures:  Written informed consent must be obtained from all subjects or legally acceptable 
representatives before any study specific screening procedures are performed.  The following 
procedures will occur per the Schedule of Assessments:  medical history, complete physical 
examination, physical measurements, vital signs, Eastern Cooperative Oncology Group 
performance status (ECOG PS), ECG, echocardiogram (ECHO), pulmonary function tests 
(PFTs), recording of concomitant medications, review of adverse events and serious adverse 
events.  Electronic clinical outcome assessments will no longer be collected after protocol 
Amendment 6.  Imaging studies for bone lesions (all subjects) and soft tissue plasmacytoma 
evaluation (if clinically indicated).  Central laboratory testing will be performed to confirm disease 
and stage including bone marrow with samples for MRD and fluorescence in-situ hybridization 
(FISH).  Additional central laboratory testing will include hematology, serum chemistry, hepatic 
and renal function.  Local laboratory testing will include coagulation factors, pregnancy testing, 
blood typing with indirect antiglobulin test (IAT), HBV serologies, and HBV DNA testing.  Samples 
will also be taken to perform pharmacokinetic (PK), pharmacodynamic (PDn), biomarker studies, 
and anti-daratumumab antibody assessments.  Subjects will be assessed for survival status and 
subsequent antimyeloma therapies will be collected during LTFU.

For a full list of study procedures, including the timing of each procedure, please refer to 
Section 7 and the Schedule of Assessments (Table 11).   
Statistical Considerations: 
The efficacy analyses of PFS and key secondary endpoints will be conducted on the full analysis 
set.  Treatment effects in efficacy endpoints will be evaluated and compared KdD vs Kd.  For 
PFS, response and disease progression will be determined by an IRC in a blinded manner.  In 
addition, response and disease progression outcomes will be determined locally by investigators 
in an unblinded manner and centrally by the sponsor using a validated computer algorithm (Onyx 
Response Computer Algorithm [ORCA]) in a blinded manner.  The primary analysis of PFS will 
be based on IRC assessed outcomes; the timing will be event driven and will happen when 
approximately 188 PFS events are reached.  The PFS outcomes assessed by the investigators 
as well as by ORCA will serve as supportive analyses of PFS. 
The primary comparison of PFS will be tested using a log rank test stratified by the randomization 
stratification factors per IxRS at 1-sided significance level of 0.025.   
If PFS is significant, the key secondary endpoints will be tested by hierarchical testing in the order 
of ORR, MRD[-]CR by NGS, and OS.  Overall response rate and MRD[-]CR will be tested once at 
the time when primary analysis of PFS is significant.  If PFS, ORR, and MRD[-]CR are all 
statistically significant at 0.025 significance level, then OS will be tested multiple times with an 
overall alpha of 0.025. 
 
  
 
 
  Overall response rate and MRD[-]CR will be analyzed using the 
Cochran-Mantel-Haenszel chi-square test controlling for the randomization stratification factors 
per IxRS.  Overall survival will be analyzed using the same method as described for the PFS 
endpoints.  
Safety data, including laboratory test results, vital signs, treatment-emergent adverse events, 
serious adverse event and treatment related events, will be summarized by actual treatment 
received.  Analysis on changes on LVEF and PFTs over time will be conducted. 
For a full description of statistical analysis methods, please refer to Section 10.

BACKGROUND AND RATIONALE 
2.1 
Multiple Myeloma 
Multiple myeloma, a clonal neoplastic proliferation of plasma cells, is the second most 
common hematologic malignancy and is responsible for approximately 80000 annual 
deaths worldwide (1 of cancer deaths).  The estimated incidence of multiple myeloma 
in 2012 worldwide was 114000 persons and this represents 0.8 of all cancers.  The 
5 year prevalence of multiple myeloma worldwide was estimated at 229000 persons 
(Ferlay et al, 2015).  Multiple myeloma is a disease of older adults, with a median age at 
diagnosis of 70 years (Howlader et al, 2013). 
2.2 
Proteasome Background 
The proteasome is a multicatalytic proteinase complex that is responsible for 
degradation of a wide variety of protein substrates within normal and transformed cells.  
Intracellular proteins targeted for degradation by the proteasome are first ubiquitinated 
via the ubiquitin conjugation system.  Ubiquitinated proteins are cleaved within the 
proteasome by 1 or more of 3 separate N terminal threonine protease activities:  a 
chymotrypsin like activity, a trypsin like activity, and a caspase like activity. 
2.3 
Amgen Investigational Product Background 
2.3.1 
Carfilzomib Background (Nonclinical) 
Carfilzomib is a tetrapeptide epoxyketone based inhibitor of the 20S proteasome.  
Carfilzomib, showed less off target activity when measured against a broad panel of 
proteases including metallo-, aspartyl-, and serine proteases compared to bortezomib; 
bortezomib showed off target inhibitory activity in the nanomolar range against several

Protocol Number:  20160275 
Date:  17 March 2021

CONFIDENTIAL 
 
 
serine proteases (Arastu-Kapur et al, 2009).  This selectivity may be responsible for the 
reductions in myelosuppression and neuropathy observed in studies comparing 
carfilzomib with bortezomib. 
Incubation of hematologic tumor cell lines with carfilzomib for as little as 1 hour led to 
rapid inhibition of proteasome activity followed by accumulation of polyubiquitinated 
proteins and induction of apoptotic cell death (Suzuki et al, 2011; Kuhn et al, 2007). 
Carfilzomib has also been administered to rats and monkeys for 6 and 9 months, 
respectively (twice weekly for 3 weeks on a 28-day cycle).  Carfilzomib was well 
tolerated at doses resulting in more than 80 proteasome inhibition, with no behavioral 
or histological evidence of peripheral neuropathy (PN) and no neutropenia (Onyx data 
on file and Carfilzomib Investigator's Brochure [IB]). 
2.3.2 
Carfilzomib Background (Clinical) 
Carfilzomib entered clinical studies in September 2005.  On 20 July 2012, Kyprolis 
(Carfilzomib for Injection) was approved under the United States Food and Drug 
Administration’s (US FDA) accelerated approval program for the treatment of patients 
with multiple myeloma who have received at least 2 prior therapies, including bortezomib 
and an immunomodulatory drug (IMiD), and have demonstrated disease progression on 
or within 60 days of completion of the last therapy.  The initial accelerated approval was 
based on the results of the phase 2 PX-171-003-A1 study in the United States.  
Subsequent full approval in the United States and globally were based on 2 phase 
3 trials:  PX 171-009 ASPIRE and 2011-003 ENDEAVOR.  Following these approvals, 
Kyprolis in combination with either lenalidomide and dexamethasone or dexamethasone 
alone is indicated for treatment of relapsed or refractory multiple myeloma (RRMM).  The 
exact indication wording varies by region.  Additional data is summarized in the IB. 
As of 19 July 2020, an estimated 4361 subjects (3976.4 subject-years) have been 
exposed to carfilzomib in company-sponsored clinical trials since the beginning of the 
development program. 
Refer to Section 4 of the Carfilzomib IB for additional information related to the physical, 
chemical, and pharmaceutical properties and formulation(s). 
2.4 
Non-Amgen Medicinal Product Background 
2.4.1 
Daratumumab Background (Non-Amgen Investigational Product) 
Daratumumab is a first in class human anti-cluster differentiation antigen 38 (CD38) 
immunoglobulin (Ig) G1 (kappa) monoclonal antibody.  CD38 is differentially expressed

during B-cell development with greatest expression on terminally differentiated B-cells.  
CD38 is an enzyme that catalyzes the metabolism of cyclic adenine dinucleotide 
phosphate ribose and nicotinic acid to adenine dinucleotide phosphate which functions 
in regulation of intracellular calcium stores.  Various preclinical experiments with multiple 
myeloma cell lines, purified multiple myeloma cells, and mononuclear cell suspensions 
have demonstrated that daratumumab triggers lysis of multiple myeloma cells by a 
variety of mechanisms.  The binding of the antibody to CD38 positions of the Fc receptor 
(FcR) in a way that optimizes interaction with complement resulting in strong 
complement dependent lysis (de Weers et al, 2011). 
Antibody dependent lysis with daratumumab has been demonstrated in complement free 
cell suspensions of multiple myeloma cells and cell lines with peripheral blood 
mononuclear cells (PBMCs) enriched for natural killer (NK) cells using both normal and 
patient PBMCs.  Other mechanisms of action (MoA) including antibody-dependent 
cellular phagocytosis (ADCP) and apoptosis triggered by FcR-crosslinking have been 
demonstrated with daratumumab (van der Veer et al, 2011b).  Analysis from clinical 
trials of daratumumab revealed an immunomodulatory role of daratumumab that leads to 
the induction of clonal T cell expansion and reduction of immune suppressive cell 
populations CD38 myeloid-derived suppressor cells (MDSC), CD38 TReg, and CD38 
BReg cells (Krejcik et al, 2016). 
Clinical activity of daratumumab was first studied in phase 1/2 Gen 501 and 
phase 2 SIRIUS trials.  A recent summary of the pooled results of these trials was 
reported (Usmani et al, 2016).  The patient population was RRMM with 2 or more prior 
lines of therapy, 76 of patients received more than 3 lines of therapy (median 5, 
range 2 to 14 lines).  A total of 148 patients were treated at the 16 mg/kg dose, 86.5 of 
patients were double refractory to both IMiD and proteasome inhibitors.  The ORR was 
31 and DOR 7.6 months with a median PFS of 4 months.  Only 4 of patients

2.4.2 
Daratumumab Mechanism of Action 
Daratumumab is a targeted immunotherapy that binds to CD38, a transmembrane 
glycoprotein that is overexpressed in multiple myeloma plasma cells.  Multiple MoA have 
been observed for daratumumab, including complement dependent cytotoxicity (CDC), 
antibody-dependent cellular cytotoxicity (ADCC), induction of apoptosis by Fc gamma 
receptor mediated crosslinking of tumor bound monoclonal antibodies, and ADCP. 
Translational biomarker studies of samples from patients treated in daratumumab 
phase 1 and phase 2 studies (Studies GEN501 and MMY2002, respectively) have 
revealed previously unknown immunomodulatory effects of daratumumab 
(Krejcik et al, 2016).  Detailed analysis by flow cytometry (FC) of changes in circulating 
immune cells demonstrated that daratumumab was able to induce large increases in 
CD8 T numbers.  Next generation T-cell receptor (TCR) sequencing was utilized to 
evaluate changes in T cell clonality.  Interestingly, in patients who responded to 
daratumumab, both the maximal individual increase in a T cell clone, as well as the sum 
of expanded T cell clones, were significantly increased suggesting that T cell expansion 
may have a role in eliminating the myeloma cells.  In order to assess the potential 
mechanism by which daratumumab could lead to these increases in T cell clones, 
additional analysis revealed that there was a rapid and sustained elimination of highly 
immunosuppressive subsets of CD38 Tregs, CD38 MDSCs, and CD38 Bregs in 
patients treated with daratumumab.  The CD38 Tregs identified is a novel population of 
Tregs that are more immunosuppressive than CD38- Tregs.  In addition, it has also been 
shown that daratumumab can modulate the enzymatic activity of CD38 and potentially 
lead to a reduction in immunosuppressive adenosine levels in the tumor 
microenvironment (Horenstein et al, 2013). 
Some of daratumumab’s most differentiating attributes are the depth of response 
achieved in responders and the drug’s multifaceted MoA.  Based upon these new 
findings, it is hypothesized that daratumumab’s deep and durable responses in patients 
with multiple myeloma are induced, in part, by the immunomodulatory activity that 
removes immune suppressive functions of CD38 MDSC, CD38 TReg, and 
CD38 BReg cells and increases T cell clonality.  A figure summarizing daratumumab’s 
novel, converging MoA is presented in Figure 1.

Previously reported to kill tumor cells by immune-mediated mechanisms, such as ADCC, 
ADCP, and CDC, as well as by programmed cell death via cross linking of the antibody 
on the cell surface, it is now known that daratumumab also induces immunomodulatory 
effects via several different pathways that contribute to killing of CD38 immune cells that 
modulate T cell activity, namely MDSC, TReg, and BReg.  This is a novel mechanism 
previously unreported that is hypothesized to drive development of multiple opportunities 
for daratumumab beyond CD38 myeloma and other heme malignancies.

2.5 
Rationale 
2.5.1 
Study Rationale 
Relapsed or refractory multiple myeloma treatment has evolved rapidly in recent years.  
ASPIRE was the first phase 3 randomized study demonstrating that a triplet using 
non-conventional chemotherapy agents had significant improvement in outcomes when 
compared with a duplet.  In this study, KRd reduced the risk of progression by 31 when 
compared to lenalidomide and dexamethasone (hazard ratio [HR]  0.69, P  0.0001; 
Stewart et al, 2015) which translated in a median PFS of 26.3 months in the KRd arm 
with consistent benefit in subgroup analyses.  These positive results were despite 
limiting carfilzomib treatment to the first 18 cycles of therapy.  Soon after, the concept of 
superior outcomes with novel agent-based triplets as treatment of early relapsed multiple 
myeloma (1 to 3 prior lines) was confirmed with other combinations (Table 1).  More 
recently, interim data from 2 phase 3 trials with daratumumab has shown improvement 
of outcomes when added to either bortezomib and dexamethasone or lenalidomide and 
dexamethasone backbones.  Compared to lenalidomide and dexamethasone for 
patients with RRMM with a median of 1 prior line of therapy, the addition of 
daratumumab reduced the risk of progression by 63 (HR  0.37, P  0.0001; 
Dimopoulos et al, 2016).  Compared to bortezomib and dexamethasone, the addition of 
daratumumab reduced the risk of progression by 61 in patients with RRMM with a 
median of 2 prior lines of therapy (HR  0.39, P  0.0001; Palumbo et al, 2016). 
Among the phase 3 studies in relapsed multiple myeloma, the results achieved with 
carfilzomib and daratumumab based combinations suggest that these 2 agents are likely 
the most potent in their respective classes.  They both have demonstrated high rates of 
overall responses and significant increment of CRRs (Table 1).  Moreover, pre-clinical 
and clinical studies combining daratumumab to proteasome inhibitors have 
demonstrated synergy (Palumbo et al, 2016; van der Veer et al, 2011a).  Therefore, it is 
expected that the combination of both agents, carfilzomib and daratumumab, would 
provide a highly efficacious treatment option for patients with relapsed disease. 
A number of ongoing phase 3 studies in newly diagnosed transplant ineligible patients 
are evaluating lenalidomide-based triplets with planned treatment to continue until 
progression (NCT01335399, NCT01850524, NCT02252172, and NCT02579863).  
Moreover, a recent meta-analysis has demonstrated OS advantage on the use of 
lenalidomide maintenance after autologous stem cell transplant (McCarthy et al, 2016).  
This information points to an increase in the number of subjects that have been exposed

to lenalidomide in first line.  Developing lenalidomide-sparing options is expected to 
address a significant unmet need in the near future for the treatment of relapsed 
myeloma.

2.5.2 
Rationale for Daratumumab Dose 
Dosing of daratumumab in subjects with multiple myeloma is recommended at 16 mg/kg 
(weekly for 8 weeks, then every 2 weeks for 16 weeks, then every 4 weeks thereafter) 
administered via intravenous (IV) until disease progression or unacceptable toxicity.  The 
dose selection was based on an acceptable safety profile, maximal clinical activity, and 
PKs consistent with saturation of the target.  The data supporting the selection of a 
16 mg/kg dose for the treatment of multiple myeloma are as follows: 
 
Safety:  Clinical safety data demonstrated that daratumumab is well-tolerated, with 
clinically manageable side effects, highlighted by the fact that no subject treated with 
16 mg/kg daratumumab monotherapy discontinued treatment as a result of a 
daratumumab related adverse event. 
 
For doses above 4 mg/kg, there was no dose dependent toxicity pattern 
observed. 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 29 of 140 
CONFIDENTIAL 
 
 
 
Clinical efficacy:  Clinical response data derived from Study GEN501 and 
Study MMY2002 show robust activity among subjects treated at 16 mg/kg with ORRs 
of 36 and 29, respectively. 
 
The response rates were consistently and significantly higher and deeper at the 
16 mg/kg dose level as compared to various schedules at the 8 mg/kg dose 
level. 
 
Pharmacokinetics:  Daratumumab exhibits target-mediated drug disposition.  
Daratumumab binds to CD38 receptors in the body and the complex with 
daratumumab is rapidly cleared.  As the dose is increased or after repeated 
administration, CD38 becomes saturated, and the impact of target binding clearance 
is minimized and PK data can indicate target saturation. 
 
Population PK and exposure-response analyses suggested that 16 mg/kg is the 
lowest tested dose at which the majority (approximately 80) of subjects 
achieved serum concentrations above the model-predicted 99 target saturation 
threshold and 90 of the maximum effect on ORR threshold. 
 
Lowering the dose would likely result in reduced efficacy, whereas increasing the 
dose may not provide further improvement of the benefit-risk profile. 
 
The initial weekly dosing schedule rapidly established efficacious concentrations.  
The every 2 week and every 4 week dosing frequencies were sufficient to 
produce serum concentration levels that maintained target saturation; thus 
reducing the risk of disease progression. 
2.5.3 
Rationale for the Combination 
The rationale for combining daratumumab with a proteasome inhibitor is supported by 
the results obtained in the CASTOR study as described above.  This study was 
conducted with bortezomib, a reversible inhibitor of the proteasome which was also 
evaluated head-to-head against carfilzomib and dexamethasone in the ENDEAVOR 
study with a similar patient population.  The results of this comparison suggest superior 
outcomes with carfilzomib with a 47 reduction in the risk of progression or death 
(HR  0.53, P  0.0001; Dimopoulos et al, 2016) and are the basis for the labeled dose 
in RRMM.  Given the orthogonal MoA of daratumumab, the addition to the carfilzomib 
and dexamethasone regimen is hypothesized to be highly efficacious and possibly result 
in a longer duration of PFS compared to the experimental arm in the CASTOR study.  
An ongoing phase 1b study is evaluating the safety of the addition of daratumumab to 
carfilzomib and dexamethasone (NCT01998971).  As of 30 June 2016, 20 subjects have 
been treated with KdD in the ongoing Study MMY1001.  The most frequently reported 
grade 3 or 4 adverse events were laboratory-related and included thrombocytopenia 
(35), neutropenia (25), and anemia (15).  Cardiac disorders were reported in 
4 subjects and were grade 1 and 2 tachycardia (2 subjects), atrial fibrillation (1 subject), 
and cardiac failure (1 subject).  No grade  3 cardiac disorder adverse events were

reported.  The subject with grade 2 cardiac failure recovered from the event and 
continued on investigational product, receiving a reduced dose of carfilzomib.  Based on 
these preliminary data, the combination of KdD is well tolerated with a safety profile that 
is consistent with the known safety profile of daratumumab or Kd. 
For the combination of these 2 agents, the initial daratumumab infusion and any 
subsequent infusions that would otherwise require a large volume (eg, 1 liter); will be 
divided in 2 days to minimize the risk of volume overload given that new or worsening 
cardiac failure has occurred following the administration of carfilzomib. 
2.5.4 
Rationale for the Carfilzomib Dose Schedule 
The dose schedule in the KdD arm is based on the objective of evaluating the effect of 
the addition of daratumumab to a well characterized carfilzomib dexamethasone 
regimen.  The safety and efficacy of 20/56 mg/m2 twice-a-week carfilzomib combined 
with dexamethasone has been defined in a randomized phase 3 trial (ENDEAVOR; 
Dimopoulos et al, 2016).  In ENDEAVOR, Kd was compared to bortezomib with 
dexamethasone (Vd) in a similar patient population proposed in this phase 3 trial 
(Study 20160275).  The carfilzomib arm proved superior at the first interim analysis for 
efficacy reducing the risk of progression or death by 47 (median PFS [Kd vs Vd]:  
18.7 months vs 9.4 months).  The median follow up for the Kd arm was 11.9 months at 
the time of the first interim analysis.  A pre-planned interim analysis for OS demonstrated 
a 21 reduction in the risk of death (median OS [Kd vs Vd] 47.6 vs 40 months).  The 
median number of weeks of carfilzomib received per subject was 48.0 in the Kd group 
(Dimopoulos et al, 2017).  At the time of this analysis, there were 212 subjects who have 
received over 1 year of therapy, 89 with more than 2 years, and 31 with more than 
3 years.  The incidence of grade 3 treatment-emergent adverse events has decreased 
over the years, from 74.1 in the first 12 months, to 52.8 between 12 and 24 months, 
44.9 between 24 and 36 months, and 29.0 in subjects with more than 36 months.  
Similarly, the rate of serious adverse events shows a decrease from 47.9 in the first 
12 months, 32.5 between 12 to 24 months, 24.7 between 24 to 36 months, and 
3.2 in subjects exposed more than 36 months (data on file).  The data to-date are 
supportive of at least 3 years exposure of carfilzomib and low-dose dexamethasone as 
done in the ENDEAVOR trial.   
Daratumumab has been successfully combined with a range of anti-myeloma therapies, 
including recently released data on successful combination with a proteasome inhibitor 
in the CASTOR study in a similar patient population.  An ongoing phase 1b study

Protocol Number:  20160275 
Date:  17 March 2021 
Page 31 of 140 
CONFIDENTIAL 
 
 
evaluating the addition of daratumumab to several standards of care includes an arm of 
carfilzomib dosed at 20/70 mg/m2 weekly in combination with daratumumab.  As of 
30 June 2016, there have been 20 subjects treated with KdD in this study with the 
observed adverse events were consistent with the known individual safety profiles for 
carfilzomib and daratumumab.  The safety profile of carfilzomib dosed at 
20/70 mg/m2 weekly in combination with dexamethasone and daratumumab is 
consistent with the known safety profiles of carfilzomib and daratumumab independently. 
Carfilzomib PKs with the 20/70 mg/m2 weekly dose showed higher Cmax (maximum 
concentration) than that with the 20/56 mg/m2 twice-a-week dose (2390 ng/mL vs 
2079 ng/mL, respectively).  Although the area under the curve is higher with 
20/56 mg/m2 twice a week (1896 nghr/mL vs 1030 nghr/mL per week), it is unlikely that 
these parameters would be modified by the addition of daratumumab.  This assumption 
is based on the short half-life of carfilzomib ( 1 hour) leading to no accumulation.  
Additionally, no drug-drug interaction is expected due to the orthogonal MoA of these 
agents and their different metabolism and elimination routes. 
Given these data, this study will evaluate the 20/56 mg/m2 twice-a-week dose schedule 
for carfilzomib in combination with daratumumab and low-dose dexamethasone in this 
phase 3 study to develop a highly efficacious regimen for RRMM patients. 
2.6 
Clinical Hypothesis 
The KdD regimen will provide significant improvement in PFS over the Kd regimen. 
3. 
EXPERIMENTAL PLAN 
3.1 
Study Design 
This is a phase 3 multicenter, open-label, randomized study in subjects with RRMM who 
have received 1 to 3 prior therapies. 
Subjects will be randomized in a 2:1 ratio to 1 of 2 arms: 
 
Arm 1:  KdD using 20/56 mg/m2 carfilzomib and 16 mg/kg daratumumab 
 
Arm 2:  Kd using 20/56 mg/m2 carfilzomib 
Randomization will be performed using an interactive voice/web response system (IxRS) 
and subjects will be stratified based on the following criteria: 
1. 
Original International Staging System (ISS) stage (variables:  albumin and beta 
2 microglobulin; strata:  Stage 1 or 2 vs Stage 3) at screening 
2. 
Prior proteasome inhibitor exposure (yes vs no)

4. 
Prior CD38 antibody therapy (yes vs no) 
Subjects will receive the study treatment determined by randomization 
 
 
, or until confirmed disease progression, unacceptable toxicity, withdrawal of 
consent, or death (whichever occurs first).  No crossover between the treatment arms 
will be allowed.  All subjects will be assessed for multiple myeloma disease response 
according to the International Myeloma Working Group-Uniform Response Criteria 
(IMWG-URC) (Appendix M) using central laboratory test results every 28  7 days.  
, disease response assessments will be 
performed every 28  7 days until confirmed PD irrespective of cycle duration including 
dose delays or treatment discontinuation.  
 
.   
Following progression or discontinuation of study drug(s), subjects will have 1 follow-up 
visit 30 days (3) after last dose of all study drug(s).  After disease progression, data 
on survival status and subsequent antimyeloma therapy will be gathered at 
 
. 
Local serology testing for hepatitis B testing (hepatitis B surface antigen [HBsAg], 
hepatitis B surface antibody [anti-HBs], and hepatitis B core antibody [anti-HBc]) will be 
performed at the next scheduled visit for all subjects that do not already have a known 
medical history of hepatitis B infection or who have not had testing conducted within the 
previous 12 weeks.  In addition, subjects with a known medical history of hepatitis B 
infection or who test positive for hepatitis B virus (HBV) serologies will be monitored 
closely for signs and symptoms of hepatitis B and will have local HBV DNA testing 
performed at their next visit and then every 12 weeks ( 2 weeks) or more frequently if 
clinically indicated through follow-up visit 1.  Subjects in arm 1 (KdD) will continue to be 
monitored and tested for 6 months following the last dose of daratumumab.  A hepatitis 
specialist should be consulted for all subjects who test positive for HBV serology or HBV 
DNA to undergo full assessment and make decisions regarding HBV reactivation 
treatment and/or confirmation whether HBV reactivation is adequately controlled 
to resume study drugs.  Subjects who have received Hepatitis B vaccination with only 
anti-HBs positivity and no clinical signs of hepatitis do not require HBV DNA monitoring.  
The overall study design is described by a study schema at the end of the 
protocol synopsis section.

SUBJECT ENROLLMENT 
Before subjects begin participation in any study-specific activities/procedures, Amgen 
requires a copy of the site’s written institutional review board/independent ethics 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 39 of 140 
CONFIDENTIAL 
 
 
committee (IRB/IEC) approval of the protocol, informed consent form (ICF), and all other 
subject information and/or recruitment material, if applicable (see Section 11.2).  All 
subjects or legally acceptable representatives must personally sign and date the 
IRB/IEC approved ICF before commencement of study-specific activities/procedures. 
A subject is considered enrolled when the investigator decides that the subject has met 
all eligibility criteria.  The investigator is to document this decision and date, in the 
subject’s medical record and in/on the enrollment case report form (CRF). 
Each subject who enters into the screening period for the study (up to 21 days before 
cycle 1 day 1) will receive a unique subject identification number before any 
study-related activities/procedures are performed.  The subject identification number will 
be assigned by the IxRS.  This number will be used to identify the subject throughout the 
clinical study and must be used on all study documentation related to that subject. 
Subjects who are determined not eligible after screening must be screen-failed in the 
IxRS and the reason for the screen-failure provided.  Subjects who are determined to be 
not eligible after screening may be rescreened once at the discretion of the investigator.  
Subjects who are determined not eligible after re-screening must be screen-failed in the 
IxRS and the reason for the screen-failure provided. 
Subjects rescreening within 21 days of the signing of the original informed consent only 
need to repeat the assessment(s) that did not originally meet the eligibility criteria; all 
other initial screening assessments do not need to be repeated.  Subjects rescreening 
greater than 21 days from the signing of the original informed consent must be 
re-consented and repeat all screening procedures. 
The subject identification number must remain constant throughout the entire clinical 
study; it must not be changed after initial assignment, including if a subject is 
rescreened. 
Subjects may only be randomized once into this study. 
5.1 
Randomization/Treatment Assignment 
Approximately 450 subjects will be randomized in a 2:1 ratio to 1 of 2 arms (as described 
in Section 3.1). 
Randomization will be performed using an IxRS and subjects will be stratified based on 
the following criteria: 
1. Original ISS stage (Stage 1 or 2 vs Stage 3) at screening 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 40 of 140 
CONFIDENTIAL 
 
 
2. Prior proteasome inhibitor exposure (yes vs no) 
3. Number of prior lines of therapy (1 vs  2) 
4. Prior CD38 antibody therapy (yes vs no) 
The randomization date is to be documented in the subject’s medical record and on the 
enrollment CRF.  Subjects must receive their first dose of study treatment within 3 days 
of randomization. 
A randomization number will be assigned to each subject by IxRS and appear on the 
IxRS randomization confirmation document.  The randomization number is different than 
the subject identification number and will not be utilized by the site as a subject identifier.

TREATMENT PROCEDURES 
6.1 
Classification of Products 
The Amgen investigational product used in this study includes:  carfilzomib. 
The non-Amgen investigational product used in this study includes:  daratumumab. 
The non-Amgen non-investigational product used in this study includes:  
dexamethasone. 
6.2 
Investigational Products 
6.2.1 
Amgen Investigational Product:  Carfilzomib 
Carfilzomib will be provided by Amgen Inc. 
Carfilzomib is supplied as a sterile, lyophilized, white to off-white powder, ready for 
reconstitution.  It is supplied for single use in 50 mL Type 1 glass vials containing 60 mg 
of carfilzomib drug product with an elastomeric stopper and flip-off lid.  Upon 
reconstitution with 
 mL of preservative-free sterile water for injection (sWFI), the 
reconstituted solution contains 2 mg/mL carfilzomib, 
 mg/mL sulfobutylether 
beta-cyclodextrim sodium (SBECD), and 
 mg/mL citrate buffer, at pH 
 to 
 
Carfilzomib is supplied in labelled cartons containing 4 single use vials per carton.  
Carfilzomib must be stored between C to C and remain protected from light. 
6.2.1.1 
Carfilzomib:  Dosage, Administration, and Schedule 
Carfilzomib will be administered as an IV infusion.  On days when more than 
1 investigational product is administered, the required order of administration is as 
follows:  dexamethasone, pre-infusion medications for daratumumab, carfilzomib, 
daratumumab, and post-infusion medications for daratumumab.  Subjects in arm 1 do 
not require prehydration, however, prehydration can be administered at investigator’s 

Product:  Carfilzomib

discretion on cycle 1 day 9 and cycle 1 day 16.  Mechanical infusion pumps are 
recommended, but gravity-dependent infusions are permitted if the 30-minute infusion 
duration can be reliably maintained.  For patients with baseline chronic hepatic 
impairment (mild, moderate), reduce the starting and subsequent doses of carfilzomib by 
25 (ie, 15 mg/m2 day 1 and 2 of cycle 1 and 42 mg/m2 day 8 cycle 1 and thereafter).  In 
case of resolution of hepatic abnormalities, dose escalation may be considered. 
Carfilzomib will be dosed twice weekly over 30  5 minutes, on days 1, 2, 8, 9, 15, and 
16 of each 28-day cycle.  The administration may be within  2 days for each scheduled 
dose.  The dose will be 20 mg/m2 on cycle 1 days 1 and 2 and 56 mg/m2 beginning on 
cycle 1 day 8 and thereafter.  See Table 13 and Table 14 to review the arm 1 and 
arm 2 dosing schedules, respectively. 
Each subject’s first dose of carfilzomib will be calculated based upon baseline body 
surface area (BSA) using the Mosteller formula.  In subjects with BSA of greater than 
2.2 m2, the dose should be capped based on a BSA of 2.2 m2.  The dose for each 
subject should not be revised unless the subject experiences a change in body weight of 
 20 in which case the BSA and dose should be recalculated.  The dose can also be 
modified in response to toxicity following the dose modification guideline tables. 
The planned dose (mg/m2), dose (mg), start date/time, stop date/time, reason for change 
in planned dose, reason for dose change/withheld, reason for dose delay, reason for 
dose interruption and package lot number of carfilzomib is to be recorded on each 
subject's electronic case report form (eCRF). 
6.2.1.1.1 
Intravenous Prehydration 
Subjects in arm 2 will receive IV prehydration prior to each carfilzomib infusion during 
cycle 1.  For subjects in arm 1, no prehydration for carfilzomib will be required on days of 
daratumumab administration. 
Prehydration will consist of 250 mL normal saline or other appropriate IV fluid. 
Thereafter, carfilzomib prehydration should only be administered if the subject’s 
condition and/or risk factors require it.  The total volume of prehydration and the reason 
for prehydration after cycle 1 will be recorded. 
6.2.1.2 
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 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021

the discontinuation, temporary delay or dose reduction, as indicated in Table 3 and 
Table 4.  The subject will be considered on protocol treatment while receiving either 
carfilzomib or daratumumab (ie, if either carfilzomib or daratumumab are discontinued or 
interrupted, the subject 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 also 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. 
Carfilzomib must be discontinued permanently if a delay of more than 6 weeks is 
required due to unresolved toxicity. 
6.2.1.3 
Carfilzomib:  Dose Reduction Levels 
Dose reduction levels of carfilzomib for toxicity management of individual subjects are 
provided in Table 2.  Subjects that require a dose level reduction and tolerate the 
reduced dose for 1 full cycle, may at the discretion of the treating physician increase the 
dose to a prior dose starting with the next cycle except when the dose reduction is due 
to:  pulmonary hypertension, pulmonary toxicity, grade 3 or worse cardiac failure, and 
drug-induced hepatotoxicity.

6.2.2.1 
Daratumumab:  Dosage, Administration, and Schedule 
Daratumumab will be administered as an IV infusion.  On days when more than 
1 investigational products are administered, the required administration is as follows:  
dexamethasone, other pre-infusion medications for daratumumab, carfilzomib, 
daratumumab, and post-infusion medications for daratumumab. 
 
On days 1 and 2 of cycle 1, daratumumab will be administered at 8 mg/kg in 
500 mL normal saline each day.   
o If the subject’s first 2 infusions of 8 mg/kg daratumumab are well-tolerated 
(defined as an absence of infusion-related reaction [IRR]  grade 1), the first 
infusion of 16 mg/kg in 500 mL normal saline will be given once weekly as a

single infusion for the remaining doses of the first 2 cycles, ie, days 8, 15, and 
22 of cycle 1; and days 1, 8, 15, and 22 of cycle 2, then every 2 weeks for 
4 cycles (cycles 3 to 6), and then every 4 weeks for the remaining cycles or 
until disease progression.   
o If the 8 mg/kg infusions are not well-tolerated (defined as IRR  grade 1), the 
dilution will be in 1000 mL of normal saline until the subject completes an 
infusion without  grade 1 IRR.  For any infusions that would require a large 
volume (eg, 1000 mL); the daratumumab dose may be divided in 2 days.  
The administration may be within  2 days for each scheduled dose.  See Table 13 to 
review the arm 1 dosing schedule. 
Each subject’s dose will be calculated based on the subject’s weight rounded to the 
nearest kilogram.  Dosing calculations do not need to be changed for weight changes 
that are  10 from baseline.  The pharmacist will calculate the required volume and 
number of vials needed.  The daratumumab infusion rates are provided in Table 5 and 
Table 6. 
The planned dose (mg/kg), dose (mg), start date/time, stop date/time, reason for change 
in planned dose, reason for dose change/withheld, reason for dose delay, reason for 
dose interruption and package lot number of daratumumab is to be recorded on each 
subject's eCRF.

See Section 7.3.10 for details on vital sign monitoring during daratumumab and other 
infusions. 
6.2.2.1.1 
Pre-infusion Medications for Daratumumab 
On daratumumab infusion days, subjects will receive the following medications 1 to 
3 hours before daratumumab infusion (and prior to carfilzomib infusion): 
1. paracetamol 650 to 1000 mg orally (PO) or IV, and 
2. antihistamine (diphenhydramine 25 to 50 mg or equivalent, PO or IV), and 
3. leukotriene inhibitor (montelukast 10 mg PO or equivalent) should be given. 
Dexamethasone is also required pre-infusion, as well as 1 day after daratumumab 
infusion.  Refer to Section 6.3.1 for additional information on dexamethasone dosing.

6.2.2.1.2 
Post-infusion Medications for Daratumumab 
Any post-infusion medication will be administered after the infusion has completed. 
For the prevention of delayed IRR, all subjects will receive long- or intermediate-acting 
corticosteroid (see Section 6.2.2.1.1).  
In the absence of infusion-related adverse events after the first 3 infusions, post-infusion 
corticosteroids should be administered per investigator discretion. 
For subjects with a higher risk of respiratory complications (eg, subjects with mild 
asthma or subjects with COPD who have an FEV1  80 at screening or developed 
FEV1  80 during the study without any medical history) the following post-infusion 
medications must be administered: 
 
antihistamine (diphenhydramine or equivalent)  
 
leukotriene inhibitor (montelukast or equivalent) 
 
short-acting 2 adrenergic receptor agonist such as salbutamol aerosol  
 
control medications for lung disease (eg, inhaled corticosteroids  long-acting 
2 adrenergic receptor agonists for subjects with asthma; long-acting bronchodilators 
such as tiotropium or salmeterol  inhaled corticosteroids for subjects with COPD) 
In addition, these at-risk subjects may be hospitalized for monitoring for up to 2 nights 
after an infusion.  If subjects are hospitalized, then their spirometry test (FEV1) should 
be performed and documented before discharge.  If these subjects are not hospitalized, 
then a follow-up telephone call should be made to monitor their condition within 48 hours 
after all infusions.  If the subject has not experienced a significant medical event but is 
hospitalized overnight only for observation, the hospitalization should not be reported as 
a serious adverse event.  Investigators may prescribe bronchodilators, 
H1-antihistamines, and corticosteroids that are deemed necessary to provide adequate 
supportive care in the event a bronchospasm occurs after subjects are released from the 
hospital/clinic.  If an at-risk subject experiences no major IRRs, then these post-infusion 
medications may be waived after 4 doses at the investigator’s discretion. 
Any post-infusion medication will be administered after the infusion has completed.

Daratumumab:  Dosage Adjustments, Delays, Rules for Withholding 
or Restarting, Permanent Discontinuation 
Individual dose modification of daratumumab is not permitted, but dose delay is the 
primary method for managing daratumumab-related toxicities. 
During a cycle, a daratumumab dose must be held if any of the following criteria below 
are met, to allow for recovery from toxicity.  The criteria for a dose delay are:

grade 4 hematologic toxicity, except for grade 4 lymphopenia 
 
grade 3 thrombocytopenia with bleeding 
 
febrile neutropenia 
 
neutropenia with infection, of any grade 
 
grade 3 or higher non-hematologic toxicities with the following exceptions:  
 
grade 3 nausea that responds to antiemetic treatment within 7 days 
 
grade 3 vomiting that responds to antiemetic treatment within 7 days 
 
grade 3 diarrhea that responds to antidiarrheal treatment within 7 days 
 
grade 3 fatigue that was present at baseline or that lasts for  7 days after the 
last administration of daratumumab 
 
grade 3 asthenia that was present at baseline or that lasts for  7 days after the 
last administration of daratumumab 
Administration of daratumumab may be restarted upon recovery from toxicity to 
grade 2 or baseline, with the exception that grade 2 laryngeal edema or grade 
2 bronchospasm must be fully recovered. 
If daratumumab administration does not commence within the prespecified window 
(Table 7) 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.

Doses of daratumumab may be delayed up to 4 weeks (cycles 1 to 6) or up to 8 weeks 
(cycle 7 and beyond).  If day 1 of a cycle is delayed, 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.  Any adverse event deemed to be related to daratumumab that requires a 
dose hold of more than 4 weeks (cycles 1 to 6) or more than 8 weeks (cycle 7 and 
beyond) will result in permanent discontinuation of daratumumab.  If a dose delay 
occurs, then PK and PDn assessments should be performed on the actual 
administration day of daratumumab, not on the original scheduled administration day.

Daratumumab can be discontinued in the event of a treatment-related toxicity that, in the 
opinion of the investigator, warrants discontinuation.  The subject will be considered on 
protocol treatment while receiving either carfilzomib or daratumumab (ie, if either 
carfilzomib or daratumumab are discontinued or interrupted, the subject is still 
considered on treatment if still taking the other investigational product).  
For subjects who are diagnosed with HBV reactivation while on daratumumab treatment, 
study treatment should be interrupted until the infection is adequately controlled (See 
Section 6.7.1). 
6.2.2.3 
Daratumumab:  Management of Infusion-related Reactions 
Subjects should be carefully observed during daratumumab infusions.  Trained study 
staff at the clinic should be prepared to intervene in case of any infusion reactions 
occurring, and resources necessary for resuscitation (eg, agents such as epinephrine 
and aerosolized bronchodilator, also 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 subjects will be dosed at the same time. 
If an IRR develops, then the infusion should be temporarily interrupted.  Subjects who 
experience adverse events during the infusion must be treated according to the 
investigator’s judgment and best clinical practice.  Subjects should be treated with 
acetaminophen, antihistamine, or corticosteroids, as needed.  Intravenous saline may be 
indicated.  For bronchospasm, urticaria, or dyspnea, subjects may require 
antihistamines, oxygen, corticosteroids, or bronchodilators.  For hypotension, subjects 
may require vasopressors.  In the event of a life-threatening IRR (which may include 
pulmonary or cardiac events) or anaphylactic reaction, daratumumab should be 
discontinued and no additional daratumumab should be administered to the subject. 
Infusion-related Reactions of Grade 1 or Grade 2 
If the investigator assesses a grade 1 to 2 IRR adverse event to be related to 
administration of study drug, then the daratumumab administration should be paused.  
When the subject's condition is stable, daratumumab administration may be restarted at 
the investigator's discretion. 
If the subject 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 subject must be withdrawn from 
daratumumab treatment.

Protocol Number:  20160275 
Date:  17 March 2021 
Page 52 of 140 
CONFIDENTIAL 
 
 
Infusion-related Reactions of Grade 3 or Higher 
For IRR adverse events (other than laryngeal edema or bronchospasm) that are 
grade 3, the daratumumab administration must be stopped and the subject must be 
observed carefully until resolution of the adverse event or until the intensity of the event 
decreases to grade 1, at which point the daratumumab administration may be restarted 
at the investigator’s discretion.  If the intensity of the adverse event returns to 
grade 3 after restart of the daratumumab administration, then the subject must be 
withdrawn from daratumumab treatment. 
For IRR adverse events that are grade 4, the daratumumab administration must be 
stopped and the subject withdrawn from daratumumab 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 
daratumumab administration, the daratumumab treatment must be discontinued. 
6.3 
Non-Amgen Non-investigational Product:  Dexamethasone 
6.3.1 
Dexamethasone:  Dosage, Administration, and Schedule 
Dexamethasone, a non-Amgen non-investigational product, will also be used in this 
study.  On days when more than 1 investigational product is administered, the required 
order of administration is as follows:  dexamethasone, pre-infusion medications for 
daratumumab, carfilzomib, daratumumab, and post-infusion medications for 
daratumumab. 
Dexamethasone 40 mg will be taken orally or by IV infusion weekly.  Dexamethasone 
must be given intravenously on cycle 1 days 1 and 2.  See Table 13 and Table 14 to 
review the arm 1 and arm 2, dosing schedules, respectively.  Dexamethasone IV or PO 
will be given on successive days, at 20 mg each treatment day on weeks with 
carfilzomib and/or daratumumab infusions.  All subjects, regardless of age, will be 
required to receive 20 mg of dexamethasone on days 1 and 2 of cycle 1 (as 
a preinfusion medication for daratumumab infusion) followed by 20 mg of 
methylprednisolone or equivalent on the third day (see Appendix N for corticosteroid 
dose equivalents).   
For days when dexamethasone is given in the absence of other IV infusion (neither 
carfilzomib nor daratumumab is scheduled), it may be given within  2 days for each

scheduled dose.  Dexamethasone will be administered at least 30 minutes (but no more 
than 4 hours) prior to carfilzomib and within 1 to 3 hours from the daratumumab dose. 
Additional details regarding dexamethasone is provided in the Investigational Product 
Information Manual. 
6.3.2 
Dexamethasone:  Dosage Adjustments, Delays, Rules for 
Withholding or Restarting, Permanent Discontinuation 
All dexamethasone administrations must be within the 2 days of the scheduled 
administration; however, it must be given on days carfilzomib and/or daratumumab will 
be administered. 
The dose, date, and time are to be recorded on each subject’s eCRF.  The reason for 
dose change of dexamethasone is also to be recorded on each subject’s eCRF. 
For conditions that do not require dexamethasone dose reduction, refer to Section 6.4. 
For subjects  75 years of age or subjects whose weekly dexamethasone dose has 
been reduced to 20 mg/week, 20 mg of dexamethasone will be given as a preinfusion 
medication for daratumumab infusion, followed by 8 mg of dexamethasone prior to 
carfilzomib infusion on days 9 and 16 of cycle 1.  Starting with cycle 2, 20 mg 
dexamethasone must be given on days daratumumab is administered (without 8 mg 
dose on subsequent carfilzomib dosing day), otherwise the 20-mg dose can be split 
across carfilzomib dosing days (eg, 12/8, 10/10, etc, as shown in Table 13 and 
Table 14). 
When carfilzomib is permanently discontinued, investigators may at their discretion omit 
dexamethasone on days when given in the absence of daratumumab based on their 
assessment of the subject’s steroid tolerance. 
Subjects in arm 1 on cycles 7 without previous IRR, may decrease or omit 
dexamethasone premedication, if the subject cannot tolerate 20 mg of dexamethasone 
or equivalent.   
6.3.2.1 
Dexamethasone:  Dose Reduction Levels 
Three dose reduction levels are defined for dexamethasone based on the age of 
subjects, as shown in Table 8.  Dose reductions are permanent, dose must not be 
increased following a dose reduction.

Dexamethasone:  Guidelines for Dexamethasone-related Toxicity 
Dexamethasone will be permanently discontinued after 3 dose reductions in subjects 
who are  75 years in the event of additional dexamethasone-related toxicities.  
Dexamethasone will be permanently discontinued after 2 dose reductions in 
subjects who are  75 years 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 subject may continue 
on treatment with the other protocol-specified drug(s). 
Guidelines for dexamethasone-related toxicities are summarized in Table 9.

institutional standards), famcyclovir (eg, 125 mg PO given 3 days, twice a day or per 
institutional standards), or valacyclovir (eg, 500 mg PO, twice a day or per institutional 
standards), dose adjustments for renal function where appropriate, initiated within 
1 week of the first dose should continue for the duration of treatment with carfilzomib 
and/or daratumumab.

6.5.2 
Thromboprophylaxis 
An anticoagulant (eg, enteric-coated aspirin at standard prophylactic dose or other 
anticoagulant or antiplatelet medication such as clopidogrel bisulfate, low molecular 
weight heparin, or warfarin), is a suggested concomitant medication in subjects based 
on an individual benefit/risk assessment (Li et al, 2016). 
6.5.3 
Tumor Lysis Syndrome Prophylaxis 
An approved uric acid-lowering agent (eg, allopurinol) in subjects at high risk for tumor 
lysis syndrome (TLS) due to high tumor burden may be prescribed at the investigator’s 
discretion, according to the package insert. 
Subjects should be well hydrated to reduce the risk of TLS and decline in renal function; 
refer to the current Carfilzomib IB for safety guidance regarding TLS. 
6.5.4 
Proton-pump Inhibitor 
Proton-pump inhibitor (omeprazole or equivalent) is required while on dexamethasone. 
6.5.5 
Bone Health Therapy 
Concomitant bone health therapy is strongly recommended for all subjects with evidence 
of lytic destruction of bone or with osteopenia (Terpos et al, 2013; Gralow et al; 2013).  
Commercially available therapies are preferred when available, and should be used 
according to the manufacturer’s recommendations, as described in the prescribing 
information, for subjects with osteolytic or osteopenic myelomatous bone disease.  
Subjects who are using bisphosphonate or monoclonal antibody therapy when they 
enter the study should continue the same treatment.  Subjects with evidence of lytic 
destruction of bone or with osteopenia who are not using a bisphosphonate or 
monoclonal antibody at the time of randomization should start a bisphosphonate or other 
bone health medications that have proven efficacy such as monoclonal antibodies as 
soon as possible during cycle 1 or 2 of treatment.  Investigators should not start 
bisphosphonate or monoclonal antibody therapy during the study, unless it has been 
agreed with the sponsor that there is no sign of disease progression. 
6.5.6 
Prophylaxis for Pneumocystis Jirovenci 
Pneumocystis jirovenci pneumonia (PJP) prophylaxis should be considered, as per 
institutional guidelines while on dexamethasone.

6.5.7 
Prophylaxis for Hepatitis B Virus 
Hepatitis B virus reactivation prophylaxis should be considered for subjects at risk (ie, 
subjects who test positive on serology or have a prior history of HBV infection) as per 
institutional standards. 
6.5.8 
Other Permitted Therapies 
The following medications and supportive therapies are examples of support therapies 
that may be used during the study: 
 
antivirals 
 
hyperglycemia medical management 
 
prevention of constipation (eg, adequate hydration, high-fiber diet, and stool 
softeners, if needed) 
 
prophylactic antiemetics, with the exception of corticosteroids 
 
colony stimulating factors, erythropoietin, and transfusion of platelets and RBCs 
 
loperamide is recommended for the treatment of diarrhea, starting at the time of the 
first watery stool.  The loperamide dose and regimen is according to institutional 
guidelines.  Prophylactic loperamide is not recommended. 
 
adequate hydration is recommended for prevention of myeloma-related kidney 
disease 
 
intravenous immunoglobulins may be given at the discretion of the investigator 
according to local guidelines, eg, where low serum IgG concentrations may result in 
recurrent upper respiratory tract infections  
6.6 
Hepatotoxicity Stopping and Rechallenge Rules 
Refer to Table 4 (carfilzomib), Section 6.2.2.2 (daratumumab), and Table 9 
(dexamethasone) for stopping and rechallenging requirements when subjects have 
abnormal hepatic laboratory values (ie, alkaline phosphatase, AST, ALT, total bilirubin) 
and/or international normalized ratio (INR) and/or signs/symptoms of hepatitis. 
For subjects who are diagnosed with HBV reactivation while on daratumumab treatment, 
study treatment should be interrupted until the infection is adequately controlled (see 
Section 6.7.1).  
6.7 
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 6.9.  Concomitant therapies are to be collected from informed consent, 
through 30 days following the last dose of all study drug(s).

For concomitant therapies being taken for the disease under study (eg, pre/post-infusion 
medications), collect therapy name, indication, dose, unit, frequency, route, start dates, 
and enter in the subject’s eCRF. 
For all other concomitant therapies (eg, those listed in Section 6.4.1), collect therapy 
name, indication, dose, unit, frequency, route, start and stop dates, and enter in the 
subject’s eCRF. 
It is recommended to follow the Eighth Joint National Committee 2014 evidence-based 
guideline for the management of high blood pressure in adults (James et al, 2014 and 
Appendix H).  For elderly subjects, it is recommended to implement the 2013 ESH and 
ESC guidelines (Mancia et al, 2013 and Appendix I). 
Any patient presenting at screening with a blood pressure outside parameter is 
suggested to have consultation with the institution’s hypertension service for treatment 
recommendation. 
6.7.1 
Management of Hepatitis B Virus Reactivation 
Local hepatitis B testing (HBsAg, anti-HBs, and anti-HBc) will be performed at the next 
scheduled visit for all subjects that do not already have a known medical history of 
hepatitis B infection or who have not had testing conducted within the previous 
12 weeks.   
Subjects with evidence of positive HBV serology or who have a known history of HBV 
infection should have consultation with a specialist in HBV and be monitored for 
clinical signs of HBV reactivation with HBV DNA testing every 12 weeks ( 2 weeks) 
or more frequently as clinically indicated during and for 30 days following the last 
dose of all study drug(s) (follow-up visit 1).  Thereafter, subjects in arm 1 (KdD) will 
continue to be monitored and have HBV DNA testing for a maximum of 6 months 
following last dose of daratumumab.  Subjects that have received Hepatitis B vaccination 
with only anti-HBs positivity and no clinical signs of hepatitis do not require HBV DNA 
testing and monitoring.  
Any subject who becomes HBV DNA positive or develops reactivation of HBV will have 
study treatment interrupted and a hepatitis specialist should be consulted to 
undergo full assessment and make decisions regarding HBV reactivation 
treatment and/or confirmation whether HBV reactivation is adequately controlled 
to resume study drugs.  In consultation with the investigator, the hepatitis 
specialist may consider and advise resumption of study treatment in subjects whose 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021

CONFIDENTIAL 
 
 
HBV reactivation is controlled and where the benefits of study treatment outweigh the 
risks.  After cessation of study therapy for any reason, any ongoing monitoring, testing, 
and anti-viral treatment should be under the guidance of a specialist in HBV. 
6.8

6.9 
Excluded Treatments and/or Procedures During Study Period 
Concurrent therapy with a marketed or investigational anticancer therapeutic or radiation 
to large marrow reserves for either a palliative or therapeutic intent is excluded.  
Long-term corticosteroids for nonmalignant conditions (eg, asthma, inflammatory bowel 
disease) equivalent to a dexamethasone dose  4.0 mg/day or prednisone  20 mg/day 
are not permitted.  Corticosteroids given short-term (up to 2 weeks) for non-malignant 
conditions are permitted provided that the cumulative dose is less than 40 mg per week 
dexamethasone equivalent.  Medical monitor should be contacted in the event that 
short-term corticosteroid use is required greater than 2 weeks or at cumulative dose of 
more than 40 mg dexamethasone equivalent. 
Vaccination with live attenuated vaccines is not permitted at any time while the 
subject is receiving study treatment.  Plasmapheresis is not permitted at any time 
while the subject is receiving study treatment.  For subjects requiring plasmapheresis 
while on study treatment, every attempt should be made to document disease status by 
IMWG criteria first.  Study treatment must be discontinued, and the subject will enter

CONFIDENTIAL 
 
 
A female is considered fertile following menarche and until becoming post-menopausal 
unless permanently sterile.  Permanent sterilization methods include hysterectomy, 
bilateral salpingectomy, and bilateral oophorectomy. 
Female in the following categories are not considered of child bearing potential: 
1. Premenopausal female with 1 of the following: 
a.  Documented hysterectomy 
b.  Documented bilateral salpingectomy 
c.  Documented bilateral oophorectomy 
Note:  Site personnel documentation from the following sources is acceptable:  
1) review of subject medical records, 2) subject medical examination, or 3) subject 
medical history interview. 
2. Premenarchal female 
3. Postmenopausal female 
a. A postmenopausal state is defined as no menses for 12 months without an 
alternative medical cause.  A high follicle stimulating hormone (FSH) level 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 FSH 
measurement is insufficient. 
b. Females on HRT and whose menopausal status is in doubt will be required to 
use 1 of the non-hormonal highly effective contraception methods if they wish 
to continue their HRT during the study.  Otherwise, they must discontinue HRT 
to allow confirmation of postmenopausal status before study enrollment. 
6.10.1 
Female Subjects 
Females of childbearing potential should be advised to avoid becoming pregnant while 
being treated with carfilzomib.  Given that carfilzomib was clastogenic in the in vitro 
chromosomal aberration test in peripheral blood lymphocytes, as a precaution, FCBP 
and/or their male partners should use highly effective contraception methods or abstain 
from sexual activity during treatment and for 30 days after treatment with carfilzomib and 
for 3 months after cessation of daratumumab treatment. 
Female subjects of childbearing potential must agree to use 1 highly effective method of 
contraception (as described in Table 10).  It cannot be excluded that the efficacy of oral 
contraceptives may be reduced during carfilzomib treatment.  In addition, due to an 
increased risk of venous thromboembolic events associated with carfilzomib, females 
should avoid the use of hormonal contraceptives that are associated with a risk of 
thrombosis during treatment with carfilzomib.  Female subjects of childbearing potential 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 63 of 140 
CONFIDENTIAL 
 
 
who are using oral contraceptives or a hormonal method of contraception that is 
associated with a risk of thrombosis should switch to an alternative non-hormonal 
method of highly effective contraception. 
Table 10.  Highly Effective Contraceptive Methods for Female Subjects 
Failure rate of  1 per year when used consistently and correctly 
 
Combined (estrogen and progestogen) hormonal contraception associated with inhibition of 
ovulation (oral, intravaginal [vaginal ring], or transdermal) 
 
Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, 
injectable, implantable) 
 
Intrauterine device (IUD) 
 
Intrauterine hormonal-releasing system (IUS) 
 
Bilateral tubal ligation/occlusion 
 
Vasectomized partner (provided that partner is the sole sexual partner of the female subject 
of childbearing potential and that the vasectomized partner has received medical 
assessment of the surgical success) 
 
Sexual abstinence:  Defined as refraining from heterosexual intercourse during the entire 
period of risk associated with the study treatments.  The reliability of sexual abstinence must 
be evaluated in relation to the duration of the study and the preferred and usual lifestyle of 
the subject. 
If a female subject is suspected of being pregnant, the protocol-required therapies must 
be stopped immediately and may not be resumed until absence of pregnancy has been 
medically confirmed. 
Lactation 
It is not known if carfilzomib is transferred into breast milk.  If the subject is breastfeeding 
and wishes to be in this study, they will be required to discontinue nursing during study 
treatment and for an additional 30 days after stopping carfilzomib. 
There is no information regarding the presence of daratumumab in human milk, the 
effects on the breastfed infant, or the effects on milk production.  Human IgG is known to 
be present in human milk. 
The developmental and health benefits of breast-feeding should be considered along 
with the mother’s clinical need for daratumumab and any potential adverse effects on the 
breast-fed child from daratumumab or from the underlying maternal condition. 
6.10.2 
Male Subjects 
If the male’s sole sexual partner is of non-childbearing potential or has had a bilateral 
tubal ligation/occlusion, he is not required to use additional forms of contraception during 
the study.  The definition of non-childbearing potential is provided above. 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 64 of 140 
CONFIDENTIAL 
 
 
Male subjects with a partner of childbearing potential must agree to not father a child 
during treatment of carfilzomib and/or daratumumab and for an additional 90 days after 
the last dose of carfilzomib and/or daratumumab. 
Contraceptive options for male subjects include: 
 
Sexual abstinence (defined as refraining from heterosexual intercourse during the 
entire period of risk associated with protocol-required therapies).  The reliability of 
sexual abstinence must be evaluated in relation to the duration of the trial and the 
preferred and usual lifestyle of the subject, or 
 
Use of a condom during treatment of carfilzomib and/or daratumumab and for an 
additional 90 days after the last dose of carfilzomib and/or daratumumab. 
The female partner is to use an acceptable method of effective contraception such as:  
hormonal, intrauterine device (IUD), intrauterine hormonal-releasing system (IUS), 
female barrier method (diaphragm, cervical cap, contraceptive sponge [a female condom 
is not an option because there is a risk of tearing when both partners use a condom]).  
Male subjects must not donate sperm during treatment of carfilzomib and/or 
daratumumab and for an additional 90 days after the last dose of carfilzomib and/or 
daratumumab. 
Male subjects with a pregnant partner must practice sexual abstinence or wear a 
condom to prevent exposure of the unborn child to carfilzomib through semen. 
6.10.3 
Unacceptable Methods of Birth Control for Male and Female 
Subjects 
Birth control methods that are considered unacceptable in clinical trials include:  periodic 
abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhea method. 
Male and female subjects of childbearing potential must receive pregnancy prevention 
counseling and be advised of the risk to fetus if they become pregnant or father a child 
during treatment of carfilzomib and/or daratumumab and for 90 days after the last dose 
of carfilzomib and/or daratumumab. 
Additional medications given during the study may alter the contraceptive requirements.  
These additional medications may require female subjects to use highly effective 
methods of contraception and for an increased length of time.  In addition, male subjects 
may also be required alter the duration and/or methods of contraception.  The 
investigator must discuss these topics with subjects.

call to subject every 12 weeks ( 2 weeks).  Details of these procedures can be found in 
Section 7.3. 
Arm 1 (KdD) subjects with evidence of positive HBV serology or with a known 
medical history of HBV infection will be monitored for clinical signs and local HBV 
DNA testing for a maximum of 6 months following the last dose of daratumumab (see 
Section 7.3.15). 
7.3 
Description of Study Procedures 
7.3.1 
Demographics 
Demographic data including sex, age, race, and ethnicity will be collected in order to 
study their possible association with subject safety and treatment effectiveness.  
Additionally, demographic data will be used to study the impact on biomarker variability 
and PKs of the protocol-required therapies. 
7.3.2 
Medical History 
The investigator or designee will collect a complete medical and surgical history that 
started within 30 days prior to informed consent.  Medical history will include information 
on the subject’s concurrent medical conditions.  Record all findings on the medical 
history CRF.  Cardiovascular risk factors which include family history of cardiovascular 
disease and smoking history will also be required. 
In addition to the medical history above, multiple myeloma history must date back to the 
original diagnosis.  For subjects who are being referred to the research site, critical 
referral information will constitute multiple myeloma information from source notes.  Prior 
lines of multiple myeloma treatment are defined as a planned course of therapy.  
Therefore, during initial treatment, the induction  autologous stem cell 
transplant  consolidation and maintenance would be considered 1 line of therapy 
(see Appendix E for additional guidance on lines of therapy). 
7.3.3 
Multiple Myeloma Frailty Index 
Subjects  65 years of age will have their frailty score assessed at screening only using 
the Multiple Myeloma Frailty Score (Appendix O; Palumbo et al, 2015). 
7.3.4 
Review of Safety Events and Current Concomitant Medications 
All adverse events, serious adverse events, and changes in concomitant medications 
must be recorded on the subject’s eCRF from informed consent to 30 days following the 
last dose of all study drug(s).  All adverse events are followed until resolution or 
stabilization. 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021

CONFIDENTIAL 
 
 
Additional information will be collected for selected cardiopulmonary adverse events 
(including dyspnea, ischemic heart disease or cardiac failure) which will include results 
of work up performed as clinically indicated and/or investigator assessment of etiology. 
7.3.5 
Concomitant and Prior Medications 
All concomitant medications must be recorded in the designated eCRF from informed 
consent to 30 days following the last dose of all study drug(s).  Prior medications are to 
be included if taken 30 days prior to informed consent.  All prior medications that 
continue after the informed consent are to be recorded as concomitant medications. 
For prior therapies, collect therapy name, indication, dose, unit, frequency, route, start 
date and stop date. 
7.3.6 
Physical Examination 
A complete physical examination is to include examination of cardiovascular and 
respiratory systems, abdominal examination, and general neurologic examination.  
Clinically significant abnormal physical examination findings identified prior to the signing 
of informed consent should be reported as part of medical history, not as adverse 
events. 
7.3.7 
Physical Measurements 
Weight (in kilograms) and height (in centimeters) will be measured (height will be 
measured only at the screening physical examination).  Body surface area will be 
determined using the Mosteller Formula (Mosteller, 1987):   
BSA (m²)  ([Height(cm) x Weight(kg)]/3600) ½ 
7.3.8 
ECOG Performance Status 
The subject’s performance status will be assessed using the ECOG performance scale 
(see Appendix D) at intervals identified in the Schedule of Assessments (Table 11). 
7.3.9 
Echocardiogram 
All subjects will have a baseline transthoracic ECHO (TTE) during screening, including 
assessments of systolic and diastolic left ventricular function and right ventricular 
function.  Screening ECHO may be done within 30 days prior to randomization, if 
performed as a part of standard of care.  Echocardiograms are to be repeated 
approximately every 6 months ( 2 weeks) from cycle 1 day 1, until end of treatment, or 
if clinically indicated.  Routine ECHO (every 6 months) should not be assessed within 
4 days after daratumumab infusion.  However, ECHO should be performed within 
72 hours of cardiac failure event initiation, regardless of the timing in relation to infusion.

7.3.10 
Vital Signs 
The following measurements must be performed:  systolic/diastolic blood pressure, heart 
rate, respiratory rate, and temperature.  Vital sign measurements are performed prior to 
administration of study drug(s) in all cycles. 
Subjects must be in a rested and calm state for at least 5 minutes before blood pressure 
assessments are conducted.  The position selected for a subject should be the same 
that is used throughout the study and documented in the medical record and on the vital 
sign CRF.  Take at least 2 blood pressure measurements spaced 1 to 2 minutes apart 
and additional measurements if the first 2 are quite different (Appendix F).  Record the 
average blood pressure on the vital sign CRF. 
The temperature location selected for a subject should be the same that is used 
throughout the study and documented on the vital signs CRF. 
Record all measurements on the vital signs CRF. 
Additional Vital Sign Measurements 
In cycles 1 and 6, an additional blood pressure measurement post-carfilzomib infusion 
will be collected (within 30 minutes of the end of infusion). 
Vital signs are to be monitored extensively on cycle 1 day 1 for the first infusion of 
daratumumab, as described below: 
 
before the start of daratumumab infusion; 
 
at 0.5, 1, 1.5, 2, and 3.5 hours after the start of the infusion; 
 
at end of infusion; and 
 
0.5 and 1 hour after the end of infusion 
For all other daratumumab infusion days, vital signs are also to be measured at the end 
of the infusion. 
7.3.11 
Electrocardiogram 
Subject must be in supine position in a rested and calm state for at least 5 minutes 
before ECG assessment is conducted.  If the subject is unable to be in the supine 
position, the subject should be in most recumbent position as possible. 
The ECG must include the following measurements:  heart rate, QRS, QT, QTc, and PR 
intervals.

CONFIDENTIAL 
 
 
The primary investigator will review all ECGs.  Once signed, the original ECG tracing will 
be retained with the subject’s source documents.  At the request of the sponsor, a copy 
of the original ECG will be made available to Amgen. 
Electrocardiograms will be required in all subjects at screening.  ECG monitoring is 
required on cycle 1 day 8 and cycle 2 day 1 at the end of the carfilzomib infusion, and as 
clinically indicated. 
7.3.12 
Pulmonary Function Tests (PFTs) 
Pulmonary function tests include spirometry to measure FEV1, FEV1, FEV1/FVC, 
FVC, diffusing capacity of the lungs for carbon monoxide (DLCO) assessment.  
Screening PFT measurements may be done within 30 days prior to randomization, if 
performed as a part of standard of care.  All subjects will have PFTs assessed 
approximately every 6 months ( 2 weeks) from cycle 1 day 1, until end of treatment with 
carfilzomib, or if clinically indicated.  Serial measurements should be performed with the 
same equipment and comparable procedure.  Avoid performing this assessment within 
4 days after daratumumab infusion.   
7.3.13 
Survival 
All subjects will be followed by telephone contact or other method approximately every 
12 weeks ( 2 weeks) after the last follow-up visit until the subject has withdrawn 
consent for further participation, is lost to follow-up, has died, 
 or 
the study is closed, whichever is earliest.  Vital status must be obtained for all subjects 
within the limits of local law.  This includes subjects who may have discontinued study 
visits with or without withdrawing consent and should include interrogation of public 
databases, if necessary.  If deceased, the date and reported cause of death should be 
obtained. 
7.3.14 
Subsequent Antimyeloma Therapies 
All subjects will be followed by telephone contact or other method to collect subsequent 
antimyeloma therapies approximately every 12 weeks ( 2 weeks) after the last 
follow-up visit until the subject has withdrawn consent for further participation, is lost to 
follow-up, has died, 
 or the study is closed, whichever is earliest.   
7.3.15 
Laboratory Assessments 
Laboratory tests including hematology and serum chemistries during scheduled visits will 
be performed at a central laboratory 
, and 
at the local laboratory thereafter.  In the absence of central laboratory values, all 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 81 of 140

local laboratory values must be recorded in the eCRF.  Subjects must fast for at 
least 9 hours before screening hematology and serum chemistries.  If central laboratory 
results for lactate dehydrogenase (LDH), bilirubin, AST, and potassium are not 
reported/available at screening, local laboratory results may be utilized if completed 
within the screening window.  Screening coagulation tests will be done at local 
laboratories.  Post-enrollment, laboratory samples may be collected and analyzed by 
local laboratories if immediate results are necessary for management of 
treatment-emergent adverse events or dosing determination.  Evaluation of lab results 
for dose determination as required per Schedule of Assessments must be documented 
prior to dosing in each cycle.  Any local lab values that lead to dose modification 
decisions must be recorded in the eCRF.  Any local laboratory results that fulfill  grade 
3 values per Common Terminology Criteria for Adverse Events (CTCAE) must be 
recorded in the eCRF. 
For cycle 1 day 1, hematology and serum chemistry panel from screening may be used 
if within 14 days of day 1.  For subsequent visits in cycle 1, hematology and chemistry 
may be completed up to 72 hours prior to scheduled dose weekly for cycle 1.  Starting in 
cycle 2, only day 1 is required. 
Subjects who do not have a prior medical history of hepatitis B or who have not had 
testing conducted within the previous 12 weeks, will be tested locally for HBsAg, 
anti-HBs, and anti-HBc at their next visit.  In addition, subjects with a clinical history of 
hepatitis B infection or who test positive for HBV serologies will be monitored closely for 
signs and symptoms of hepatitis B and will have local HBV DNA testing performed at 
their next visit and then every 12 weeks ( 2 weeks) or more frequently if clinically 
indicated through follow-up visit 1.  Subjects in arm1 (KdD) will continue to be monitored 
and tested for 6 months following the last dose of daratumumab.

Pregnancy Evaluation 
For FCBP, a serum pregnancy test that is confirmed negative within 15 days prior to first 
dose of study drug and a negative urine pregnancy test within the 24 hours prior to first 
dose is required for eligibility determination and is to be performed at the local 
laboratory.  In addition to the pregnancy test conducted for eligibility, a urine or serum 
pregnancy test must be locally confirmed negative on day 1 of each cycle prior to 
dosing.  More frequent pregnancy tests may be conducted if required per local 
regulations. 
7.3.17 
Blood Typing and IAT 
Blood type, Rh, and IAT should be done before the first dose of daratumumab.  Subject 
RBC phenotyping (standard or extended) is an alternative option to the IAT test, if locally 
required.  Either method must be completed prior to first daratumumab infusion. 
Daratumumab interferes with the IAT, which is a routine pre-transfusion test performed 
to identify a patient’s antibodies to minor antigens so that suitable donor blood can be 
given for transfusion.  Daratumumab does not interfere with ABO/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.  Subjects will receive a patient 
identification wallet card for the study that includes the blood profile (ABO, Rh, and IAT 
or phenotyping) determined before the first infusion of daratumumab along with 
information on the IAT interference for healthcare providers/blood banks.  Subjects are 
to carry this card throughout the treatment period and for at least 6 months after 
treatment ends.  Blood banks can eliminate the daratumumab IAT interference with IAT 
by treating reagent RBCs with dithiothreitol (DTT; Chapuy et al, 2015). 
Possible methods for blood banks to provide safe RBCs for transfusion to subjects 
receiving daratumumab include: 
 
Providing ABO/RhD compatible, phenotypically (standard or extended phenotyping) 
or genotypically matched units 
 
Providing ABO/RhD compatible, K-negative units after ruling out or identifying 
alloantibodies using DTT-treated reagent RBCs 
Uncrossmatched, ABO/RhD compatible RBC units should be administered if transfusion 
is needed emergently as per local blood bank practice.

Antibody Testing Procedures 
Serum from venous blood samples collected from all subjects in arm 1 will be assessed 
for the generation of antibodies to daratumumab (immunogenicity) on day 1 of cycles 1, 
7, and 12 according to Table 11.  Serum samples will be screened for antibodies binding 
to daratumumab and serum titer will also be determined from confirmed positive 
samples using validated immunoassay methods.  Other immunogenicity analyses (eg, 
assessment of neutralizing capabilities) may be performed to further characterize the 
immune responses that are generated.  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.  Procedures for sample collection, preparation, identification, 
storage, and shipment will be provided in the Laboratory Manual or equivalent 
document. 
7.3.21 
Tumor Response and Multiple Myeloma Disease Assessment 
, disease assessments will be based on 
central laboratory data obtained every 28  7 days until confirmed PD (Section 7.3.21.5) 
irrespective of cycle duration including dose delays and treatment discontinuation.  For 
subjects who do not progress during treatment, disease assessments will continue to be 
measured (by the central laboratory) until PD 
 
 
.  Locally obtained disease 
assessment values will not be recorded in the eCRF. 
Disease response and progression assessments include:  SPEP, UPEP, SFLC, serum 
and urine immunofixation (SIFE, UIFE, respectively) (Section 7.3.21.1), bone marrow 
sample evaluation (Section 7.3.21.2), serum calcium, bone lesion evaluation 
(Section 7.3.21.3), and plasmacytoma evaluation (Section 7.3.21.4). 
7.3.21.1 
SPEP, UPEP, SFLC, SIFE, and UIFE 
, serum protein electrophoresis, UPEP, 
SIFE, UIFE, and SFLC will all be conducted at the central laboratory every 28  7 days 
(starting from cycle 1 day 1) irrespective of cycle duration including dose delays and 
treatment discontinuation.  Blood will be obtained for SFLC, SPEP, and SIFE.  
Twenty-4 hour urine samples will be obtained for UPEP and UIFE.  Results for SPEP, 
UPEP, or SFLC must be available at screening and before randomization.  Serum

protein electrophoresis (SPEP), UPEP, and SFLC will be repeated on cycle 1 day 
1 (unless screening values are within 14 days of cycle 1 day 1).  Post cycle 1 day 1, 
UPEP and UIFE will be measured every disease assessment as well as SPEP.  
 
 
. 
Subjects will be evaluated for disease response and progression according to the IMWG 
response criteria in Appendix M.  Disease status categories include CR, VGPR, PR, SD, 
and PD.  
, investigator evaluation of 
disease response is to be based solely on the central laboratory results, not on local 
laboratory results for laboratory-based parameters. 
The following confirmation assessments are required for all response categories (sCR, 
CR, VGPR, PR, and MR; refer to definitions in Appendix M): 
 
All response categories require 2 consecutive assessments made at any time before 
initiation of any new therapy 
 
All categories also require no known evidence of progression including new bone 
lesions if radiographic studies were performed   
 
Confirmation of CR or sCR requires bone marrow assessment (aspirate or biopsy) 
 
Extramedullary plasmacytoma evaluation (if present at screening) 
For subjects with light chain multiple myeloma, both serum and urine IFE test and SFLC 
assay will be performed every disease assessment.   
7.3.21.2 
Bone Marrow Sample Evaluation Including FISH and MRD[-]CR 
Assessment 
A baseline bone marrow sample (aspirate slides and/or biopsy) will be collected prior to 
first dose and will be used to confirm the diagnosis and quantify the percent () of 
myeloma cell involvement.  Biopsy or aspirate slides obtained as standard of care may 
be used as baseline if taken within 45 days prior to randomization and are sent to the 
central laboratory for processing.  The priority of bone marrow aspirate testing at 
screening (prior to dosing at cycle 1 day 1) is MRD NGS, FISH, cytomorphology, 
pharmacogenetics, and biomarker bone marrow aspirate.  All other bone marrow 
aspirate assessments include MRD NGS, cytomorphology, and pharmacogenetics. 
Additional bone marrow aspirate will be obtained as clinically indicated to confirm a 
response of CR.  In addition, a bone marrow aspirate will be obtained for MRD 
assessment at all of the following time points: 
 
at a fixed, landmark analysis at 12 months ( 4 weeks)

CONFIDENTIAL 
 
 
 
12 months calculated from baseline (cycle 1 day 1) 
 
this sample is collected from subjects who have not had confirmed disease 
progression 
 
if subject reached CR prior to the 12 month landmark and the CR sample was 
taken within 4 months, no additional sample is required, unless clinically 
indicated 
 
when a subject reaches CR and did not have a bone marrow aspirate sample taken 
for MRD analysis within the past 4 months, unless there is a clinical reason to repeat 
the assessment 
 
this sample may be collected/saved at the same time when the cytomorphology 
sample is collected for the confirmation of CR (per IMWG-URC criteria described 
in protocol Appendix M) 
 
at 24 months ( 4 weeks) for all subjects that have reached a CR (at any time prior to 
the 24 month timepoint) and have not had an MRD assessment within the past  
4 months, unless there is a clinical reason to repeat the assessment 
 
24 months is calculated from baseline (cycle 1 day 1) 
 
this sample is collected from all subjects who reached CR at any time prior to the 
24 month timepoint and are still receiving treatment or have not progressed and 
still attend site for disease assessment visits 
Samples for MRD analysis are not collected from subjects who have PD confirmed or 
have withdrawn consent related to this study assessment.  Samples for MRD analysis 
are not required 
. 
7.3.21.3 
Bone Lesion Assessment (Skeletal Survey, CT, or PET/CT) 
Skeletal survey will include lateral radiograph of the skull, anteroposterior and lateral 
views of the spine, and anteroposterior views of the pelvis, ribs, femora, and humeri.  
Low-dose whole body computed tomography (LD WBCT) or 
fluorodeoxyglucose-positron emission tomography/computed tomography 
(FDG-PET/CT) may be used in place of skeletal survey.  Bone lesion assessment (all 
subjects) will be conducted at screening (may be within 30 days prior to randomization) 
and will be repeated if worsening clinical symptoms suggest PD, or as clinically 
indicated.  The same method of assessment used at baseline will be used throughout 
the study.  These imaging studies will be read locally. 
7.3.21.4 
Extramedullary Plasmacytoma 
Extramedullary plasmacytoma evaluation will be conducted at screening only if a lesion 
is suspected clinically.  The evaluation may be done within 30 days prior to 
randomization, if performed as a part of standard of care.  If an extramedullary 
plasmacytoma is detected, evaluation will be repeated during treatment only to confirm a 
response of PR or better, or to confirm PD or as clinically indicated.  Assessment of

measurable sites of extramedullary disease will be performed and evaluated locally 
every 28 days (for physical examination) for subjects with a history of plasmacytomas or 
as clinically indicated during treatment for other subjects until confirmed CR or confirmed 
disease progression.  If assessment can only be performed radiologically, then 
evaluation of extramedullary plasmacytomas may be done every 12 weeks.  The same 
technique (which may include clinical evaluation by palpation, ultrasound, CT scan, 
magnetic resonance imaging (MRI), or PET/CT should be employed for each 
measurement of plasmacytoma dimensions as clinically appropriate (refer to 
Appendix M).  Bidimensional lesion measurements must be performed and recorded in 
the designated eCRF.   
7.3.21.5 
Progressive Disease Assessment 
, progressive disease (including PD due 
to development of hypercalcemia attributed solely to recurrence/progression of multiple 
myeloma) must be based on central laboratory evaluation.  Confirmation of PD (using 
2 consecutive assessments) will be required only when it is determined by central 
laboratory evaluations and not if identified via imaging as per IMWG-URC criteria, if 
progression is defined by such laboratory evaluations.  Local laboratory evaluation will 
not be accepted.  The assessments outlined in Appendix M are required for PD.  
Subjects will be considered to have progressive disease if they meet the criteria for 
progression by a variable that was not considered measurable at baseline; however, for 
patients who had a measurable serum or urine M-spike at baseline, progression cannot 
be defined by increases in SFLC alone (Kumar et al, 2016).  
 
 
. 
7.4 
Biomarker Development 
Minimal residual disease in bone marrow is a mandatory biomarker measurement in this 
study.  Minimal residual disease will be measured by a NGS based assay.  Bone marrow 
aspirates will be collected prior to first dose from each screened, consenting subject and 
at 12 months ( 2 weeks).  The bone marrow aspirates will be processed and stored 
according to a protocol that is provided to the central laboratory.  The samples will be 
analyzed centrally by the NGS-based MRD assay.  See Section 7.3.21.2 for details on 
priority of samples for bone marrow aspirate testing. 
Whole blood will be collected from participating subjects at screening, cycle 1 day 15, 
cycle 3 day 1, cycle 6 day 1, and at follow-up to explore the relationship between

CONFIDENTIAL 
 
 
serum- and plasma-based biomarkers and subject response to treatment.  Plasma 
collected at study start, cycle 13 day 1, at follow-up, and upon achievement of CR, will 
be used for isolation and analysis of circulating tumor DNA (ctDNA).  ctDNA will be 
analyzed by DNA-sequencing for the determination of biomarkers, including but not 
limited to, disease progression, treatment resistance, and patient-specific DNA 
mutations associated with MRD.  Serum collected at study start will be analyzed by 
enzyme-linked immunosorbent assay (ELISA) for the determination of biomarkers 
including, but not limited to, soluble CD38 (sCD38) protein. 
7.5 
Pharmacogenetic Studies 
If the subject consents to the optional pharmacogenetic portion of this study, DNA 
analyses may be performed.  These optional pharmacogenetic analyses focus on 
inherited genetic variations to evaluate their possible correlation to the disease and/or 
responsiveness to the therapies used in this study.  The goals of the optional studies 
include the use of genetic markers to help in the investigation of multiple myeloma 
and/or to identify subjects who may have positive or negative response to 
protocol-required therapies.  Saliva samples (collected predose on cycle 1 day 1, 
specifically for this optional test) and bone marrow aspirates (collected predose on 
cycle 1 day 1 and the first follow-up visit, as part of required protocol assessments) are 
collected for this part of the study.  For subjects who consent to this/these 
analysis/analyses, DNA may be extracted. 
Bone marrow aspirate collected will be subjected to CD138 enrichment to isolate 
malignant plasma cells and these malignant cells will then be used for both RNA- and 
DNA-sequencing to identify genomic alterations that may be associated with prognosis 
or prediction of drug response (see Section 7.3.21.2 for details on priority of samples for 
bone marrow aspirate testing).  Saliva will be used to isolate genomic DNA (gDNA) for 
use in DNA sequencing, to assist in the identification of tumor-specific mutations in the 
bone marrow.

7.6 
Sample Storage and Destruction  
Any blood, biomarker, PK, or PDn samples collected according to the Schedule of 
Assessments (Table 11) can be analyzed for any of the tests outlined in the protocol and 
for any tests necessary to minimize risks to study subjects.  This includes testing to 
ensure analytical methods produce reliable and valid data throughout the course of the 
study.  This can also include, but is not limited to, investigation of unexpected results, 
incurred sample reanalysis, and analyses for method transfer and comparability. 
All samples and associated results will be coded with a unique identification number 
prior to being shipped from the site for analysis or storage.  Samples will be tracked 
using a unique identifier that is assigned to the samples for the study.  Test results are 
stored in a secure database to ensure confidentiality.   
If informed consent is provided by the subject, Amgen can do additional testing on 
remaining samples (ie, residual and back-up) to investigate and better understand 
multiple myeloma, the dose response and/or prediction of response to carfilzomib or 
other protocol-specified therapy, and characterize aspects of the molecule 
(eg, MoA/target, metabolites).  Results from these analyses are to be documented and 
maintained, but are not necessarily reported as part of this study.  Samples can be 
retained for up to 20 years.   
Since the evaluations are not expected to benefit the subject directly or to alter the 
treatment course, the results of pharmacogenetic, biomarker, or other exploratory 
studies are not placed in the subject’s medical record and are not to be made available 
to the subject, members of the family, the personal physician, or other third parties, 
except as specified in the informed consent. 
The subject retains the right to request that the sample material be destroyed by 
contacting the investigator.  Following the request from the subject, the investigator is to 
provide the sponsor with the required study and subject identification number so that any 
remaining blood, urine, saliva, or bone marrow samples and any other components from 
the cells can be located and destroyed.  Samples will be destroyed once all 
protocol-defined procedures are completed.  However, information collected from 
samples prior to the request for destruction, will be retained by Amgen. 
The sponsor is the exclusive owner of any data, discoveries, or derivative materials from 
the sample materials and is responsible for the destruction of the sample(s) at the 
request of the subject through the investigator, at the end of the storage period, or as

appropriate (eg, the scientific rationale for experimentation with a certain sample type no 
longer justifies keeping the sample).  If a commercial product is developed from this 
research project, the sponsor owns the commercial product.  The subject has no 
commercial rights to such product and has no commercial rights to the data, information, 
discoveries, or derivative materials gained or produced from the sample.  
See Section 11.3 for subject confidentiality. 
8. 
WITHDRAWAL FROM TREATMENT, PROCEDURES, AND STUDY 
8.1 
Subjects’ Decision to Withdraw 
Subjects have the right to withdraw from the study at any time and for any reason 
without prejudice to their future medical care by the physician or at the institution. 
Subjects (or a legally acceptable representative) can decline to continue receiving 
investigational product and/or other protocol-required therapies or procedures at any 
time during the study but continue participation in the study.  If this occurs, the 
investigator is to discuss with the subject the appropriate processes for discontinuation 
from investigational product, device or other protocol-required therapies and must 
discuss with the subject the options for continuation of the Schedule of Assessments 
(Table 11) including different options of follow-up (eg, in person, by phone/mail, through 
family/friends, in correspondence/communication with other treating physicians, from the 
review of medical records) and collection of data, including endpoints, adverse events, 
as applicable.  Subjects who have discontinued investigational product and/or protocol 
required therapies or procedures should not be automatically removed from the study.  
Whenever safe and feasible it is imperative that subjects remain on-study to ensure 
safety surveillance and/or collection of outcome data.  The investigator must document 
the level of follow-up that is agreed to by the subject.    
Withdrawal of consent for a study means that the subject does not wish to receive 
further protocol-required therapies or procedures, and the subject does not wish to or is 
unable to continue further study participation.  Subject data up to withdrawal of consent 
will be included in the analysis of the study, and where permitted, publically available 
data can be included after withdrawal of consent.  The investigator is to discuss with the 
subject appropriate procedures for withdrawal from the study.

SAFETY DATA COLLECTION, RECORDING, AND REPORTING 
9.1 
Definition of Safety Events 
9.1.1 
Adverse Events 
An adverse event is defined as any untoward medical occurrence in a clinical trial 
subject.  The event does not necessarily have a causal relationship with study treatment.  
The investigator is responsible for ensuring that any adverse events observed by the 
investigator or reported by the subject are recorded in the subject’s medical record.   

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 93 of 140 
CONFIDENTIAL 
 
 
The definition of adverse events includes worsening of a pre-existing medical condition.  
Worsening indicates that the pre-existing medical condition or underlying disease 
(eg, diabetes, migraine headaches, gout) has increased in severity, frequency, and/or 
duration more than would be expected, and/or has an association with a significantly 
worse outcome than expected.  A pre-existing condition that has not worsened more 
than anticipated (ie, more than usual fluctuation of disease) during the study or involves 
an intervention such as elective cosmetic surgery or a medical procedure while on study, 
is not considered an adverse event.   
If the severity of an adverse event changes from the date of onset to the date of 
resolution, record as a single event with the highest grade (grade 1 to 4) on the Events 
eCRF.  Record a grade 5 adverse event as a separate event with a 1 day duration. 
For situations when an adverse event or serious adverse event is due to multiple 
myeloma report all known signs and symptoms.  Death due to disease progression in 
the absence of signs and symptoms should be reported as the primary tumor type 
(eg, multiple myeloma).  
Note:  The term “disease progression” should not be used to describe the 
disease-related event or adverse event.   
The investigator’s clinical judgment is used to determine whether a subject is to be 
removed from treatment due to an adverse event.  In the event a subject, or subject’s 
legally acceptable representative requests to withdraw from protocol-required therapies 
or the study due to an adverse event, refer to Section 8.1 for additional instructions on 
the procedures recommended for safe withdrawal from protocol-required therapies or 
the study. 
9.1.2 
Serious Adverse Events 
A serious adverse event is defined as an adverse event that meets at least 1 of the 
following serious criteria: 
 
fatal 
 
life threatening (places the subject at immediate risk of death) 
 
requires in-patient hospitalization or prolongation of existing hospitalization 
(exceptions:  hospitalized due to long infusion time of study drugs or if hospitalized 
overnight only for observation as described in Section 6.2.2.1.2) 
 
results in persistent or significant disability/incapacity 
 
congenital anomaly/birth defect 
 
other medically important serious event 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021 
Page 94 of 140 
CONFIDENTIAL 
 
 
An adverse event would meet the criterion of “requires hospitalization,” if the event 
necessitated an admission to a health care facility (eg, overnight stay). 
If an investigator considers an event to be clinically important, but it does not meet any 
of the serious criteria, the event could be classified as a serious adverse event under the 
criterion of “other medically important serious event.”  Examples of such events could 
include allergic bronchospasm, convulsions, blood dyscrasias, drug-induced liver injury, 
or events that necessitate an emergency room visit, outpatient surgery, or urgent 
intervention. 
9.2 
Safety Event Reporting Procedures  
9.2.1 
Adverse Events 
9.2.1.1 
Reporting Procedures for Adverse Events That Do Not Meet Serious 
Criteria 
The investigator is responsible for ensuring that all adverse events observed by the 
investigator or reported by the subject that occur after signing of ICF through 30 days 
after the last dose of study treatment or the follow-up visit (whichever is later) are 
reported using the Event CRF.  All adverse events of HBV reactivation for 
arm 1 subjects with evidence of positive HBV serology or known medical history 
of HBV infection are required to be reported through end of study. 
The investigator must assign the following adverse event attributes: 
 
adverse event diagnosis or syndrome(s), if known (if not known, signs or symptoms), 
 
dates of onset and resolution (if resolved), 
 
severity (and/or toxicity per protocol), 
 
assessment of relatedness to investigational product(s) or other protocol-required 
therapies, and 
 
action taken. 
The adverse event grading scale used will be the Amgen adverse event standard 
grading score; Common Terminology Criteria for Adverse Events (CTCAE).  The grading 
scale used in this study is described in Appendix A. 
The investigator must assess whether the adverse event is possibly related to the 
investigational product(s).  This relationship is indicated by a “yes” or “no” response to 
the question:  Is there a reasonable possibility that the event may have been caused by 
the investigational product(s)? 
The investigator must assess whether the adverse event is possibly related to any 
study-mandated activity (eg, administration of investigational product, protocol-required

therapies, use of medical device(s) and/or procedure (including any screening 
procedure(s)).  This relationship is indicated by a “yes” or “no” response to the question:  
“Is there a reasonable possibility that the event may have been caused by a study 
activity (eg, administration of investigational product, protocol-required therapies, use of 
medical device(s)), and/or procedure”?  
The Investigator is expected to follow reported adverse events until stabilization or 
reversibility.  
9.2.1.2 
Reporting Procedures for Serious Adverse Events 
The investigator is responsible for ensuring that all serious adverse events observed by 
the investigator or reported by the subject that occur after the subject signing of the 
informed consent through end of study are recorded in the subject’s medical record and 
are submitted to Amgen.  All serious adverse events must be submitted to Amgen within 
24 hours following the investigator’s knowledge of the event via the Event CRF.   
If the electronic data capture (EDC) system is unavailable to the site staff to report the 
serious adverse event, the information is to be reported to Amgen via an electronic 
Serious Adverse Event Contingency Report Form within 24 hours of the investigator’s 
awareness of the event.  See Appendix B for a sample of the electronic Serious 
Adverse Event Contingency Report Form.  For EDC studies where the first notification of 
a Serious Adverse Event is reported to Amgen via the eSerious Adverse Event 
Contingency Report Form, the data must be entered into the EDC system when the 
system is again available.   
The investigator must assess whether the serious adverse event is possibly related to 
the investigational product(s).  This relationship is indicated by a “yes” or “no” response 
to the question:  Is there a reasonable possibility that the event may have been caused 
by the investigational product(s)?  Relatedness means that there are facts or reasons to 
support a relationship between investigational product and the event. 
The investigator is expected to follow reported serious adverse events until stabilization 
or reversibility.  
New information relating to a previously reported serious adverse event must be 
submitted to Amgen.  All new information for serious adverse events must be sent to 
Amgen within 24 hours following knowledge of the new information.  If specifically 
requested, the investigator may need to provide additional follow-up information, such as 
discharge summaries, medical records, or extracts from the medical records.

Protocol Number:  20160275 
Date:  17 March 2021 
Page 96 of 140 
CONFIDENTIAL 
 
 
Information provided about the serious adverse event must be consistent with that 
recorded on the Event CRF. 
If a subject is permanently withdrawn from protocol-required therapies because of a 
serious adverse event, this information must be submitted to Amgen. 
9.2.1.3 
Reporting Serious Adverse Events After the Protocol-required 
Reporting Period 
There is no requirement to monitor study subjects for serious adverse events following 
the protocol-required reporting period (as defined in Section 9.2.1.2) or after end of 
study.  However, these serious adverse events should be reported to Amgen 
(regardless of causality).  Per local requirements, in some countries (eg, European 
Union [EU] member states), investigators are required to report serious adverse events 
that they become aware of after end of study.  If serious adverse events are reported, 
the investigator has to report them to Amgen within 24 hours following the investigator’s 
awareness of the event. 
Serious adverse events reported outside of the protocol-required reporting period will be 
captured within the safety database as clinical trial cases and handled accordingly 
based on relationship to investigational product.  
9.2.1.4 
Method of Detecting Adverse Events and Serious Adverse Events 
Care will be taken not to introduce bias when detecting adverse events and/or 
serious adverse events.  Open-ended and non-leading verbal questioning of the 
subject is the preferred method to inquire about adverse event occurrence. 
9.2.1.5 
Regulatory Reporting Requirements for Serious Adverse Events 
If subject is permanently withdrawn from protocol-required therapies because of a 
serious adverse event, this information must be submitted to Amgen. 
Prompt notification by the investigator to the sponsor of serious adverse events is 
essential so that legal obligations and ethical responsibilities towards the safety 
of subjects and the safety of a study treatment under clinical investigation are 
met.  
The sponsor has a legal responsibility to notify both the local regulatory authority 
and other regulatory agencies about the safety of a study treatment under clinical 
investigation.  The sponsor will comply with country-specific regulatory 
requirements relating to safety reporting to the regulatory authority, IRBs/IECs, 
and investigators.

Protocol Number:  20160275 
Date:  17 March 2021 
Page 97 of 140 
CONFIDENTIAL 
 
 
Individual safety reports must be prepared for suspected unexpected serious 
adverse reactions according to local regulatory requirements and sponsor policy 
and forwarded to investigators as necessary. 
An investigator who receives an individual safety report describing a serious 
adverse event or other specific safety information (eg, summary or listing of 
serious adverse events) from the sponsor will file it along with the Investigator’s 
Brochure and will notify the IRB/IEC, if appropriate according to local 
requirements. 
9.2.1.6 
Safety Monitoring Plan 
Subject safety will be routinely monitored as defined in Amgen’s safety 
surveillance and signal management processes. 
9.3 
Pregnancy and Lactation Reporting 
If a female subject becomes pregnant, or a male subject fathers a child, while the 
subject is taking carfilzomib report the pregnancy to Amgen Global Patient Safety as 
specified below. 
In addition to reporting any pregnancies occurring during the study, investigators should 
report pregnancies that occur 30 days after the last dose of carfilzomib or 3 months after 
the cessation of daratumumab treatment.  For male subjects, investigators should report 
pregnancies that occur during treatment and for an additional 90 days after the last dose 
of carfilzomib and/or daratumumab (whichever was given last). 
The pregnancy should be reported to Amgen Global Patient Safety within 24 hours of 
the investigator’s awareness of the event of a pregnancy.  Report a pregnancy on the 
Pregnancy Notification Form (Appendix C).  Amgen Global Patient Safety will follow-up 
with the investigator regarding additional information that may be requested.  
If a female subject becomes pregnant during the study or within 30 days after the last 
dose of carfilzomib or within 3 months after the last dose of daratumumab, the 
investigator should attempt to obtain information regarding the birth outcome and health 
of the infant.  
If the outcome of the pregnancy meets a criterion for immediate classification as a 
Serious Adverse Event (eg, female subject experiences a spontaneous abortion, 
stillbirth, or neonatal death or there is a fetal or neonatal congenital anomaly) the 
investigator will report the event as a Serious Adverse Event.

If a female breastfeeds while taking protocol-required therapies report the lactation case 
to Amgen as specified below.  In addition to reporting a lactation case during the study, 
investigators should report lactation cases that occur 30 days after the last dose of 
carfilzomib or 3 months after the last dose of daratumumab. 
Any lactation case should be reported to Amgen Global Patient Safety within 24 hours of 
the investigator’s awareness of event.  Report a lactation case on the Lactation 
Notification Form (Appendix C).  Amgen Global Patient Safety will follow-up with the 
investigator regarding additional information that may be requested. 
If a male subject's female partner becomes pregnant while taking protocol-required 
therapies or within 90 days after the last dose of carfilzomib and/or daratumumab 
(whichever was given last), the investigator should discuss obtaining information 
regarding the birth outcome and health of the infant from the pregnant partner.

Incomplete adverse event start dates, concomitant medications start or stop dates, and 
death date will be imputed, and the detailed rules will be specified in statistical analysis 
plan (SAP).  No imputation will be done for the primary analysis of the primary and key 
secondary endpoints.  The frequency of missing disease assessments and deviation of 
the actual disease assessment times from the scheduled assessment times will be 
summarized by treatment arms.  Sensitivity analyses will be performed to assess the 
impact on the analysis of PFS due to any missing data/assessment, and any lost to 
follow-up or discontinuation of assessment of PFS not due to an event.  Similar analysis 
will be performed for QoL endpoints.  
Details of missing data analysis and imputation rules will be described in SAP. 
10.2 
Sample Size Considerations 
One hundred eighty-eight PFS events are required to have at least 90 power to 
demonstrate superiority at an alternative HR of 0.6 (arm 1 vs arm 2), using a log rank 
test at 1-sided overall significance level of 0.025.  
 
 
  With 450 subjects randomized (300 in arm 1 vs 150 in arm 2), 
it is anticipated that 188 events will be accrued at approximately 27 months after the first 
subject is randomized assuming events follow an exponential distribution.  
 
 
 
  
 
 
 
 
  The description of sample size calculation for log-rank test 
factoring in accrual and dropout can be found in Lachin and Foulkes, 1986; 
Lakatos, 1988; and Chow et al, 2003.  The actual timing of primary analysis will be 
determined by actual enrollment rate, dropout rate, and PFS event rate; hence, it is 
subject to change as these factors may vary in the study.  The minimum detectable PFS 
HR is approximately 0.738 (corresponding to about 36 improvement in PFS) at the 
primary analysis.  Amgen may choose to increase sample size upon observation of 
slower than expected PFS event rate. 
 
  It is based

on safety and survival follow-up as described in Section 3.5.2.  It is not directly linked to 
sample size calculation based on the primary endpoint of PFS outlined in this section. 
The sample size calculation was performed using East software (Version 6.3 or above). 
10.3 
Planned Analyses 
10.3.1 
Data Monitoring Committee (DMC) 
An independent DMC will be convened for this study and will act in an advisory capacity 
to the sponsor with respect to safeguarding the interests of study subjects, assessing 
 safety and efficacy data, monitoring the overall conduct of the study, and 
providing with recommendations relating to continuing, modifying, or stopping the study 
based on these findings (International Council for Harmonisation Good Clinical Practice 
[ICH GCP 5.5.2]).  Details of the DMC will be described in the DMC Charter.  The initial 
assessment from this committee will be planned after 30 subjects (approximately 20 for 
the experimental arm and 10 for the control arm) have been enrolled and have finished 
the first cycle of treatment to ensure safety of all arms.  A provision will be made allowing 
an early follow-up DMC meeting to be decided at the time of the initial assessment.  The 
DMC will meet approximately every 6 months until the Primary Analysis is 
completed. 
10.3.2 
Independent Review Committee (IRC) 
The membership criteria and operational details of the IRC will be described in the IRC 
Charter.  The primary responsibility of the IRC is the independent assessment of 
individual patient efficacy outcomes in accordance with the IMWG-URC.  The IRC will 
centrally review the disease related tests and assessments (Section 7) to evaluate 
disease progressions and responses without the knowledge of randomization 
assignments.  The IRC assessment will be used for the primary analysis of endpoints. 
10.3.3 
Primary Analysis 
The timing for the primary analyses of PFS for arm 1 vs arm 2 will be event driven and 
will happen when approximately 188 PFS events are reached cumulatively in these 
2 arms.

Planned Methods of Analysis  
10.4.1 
General Considerations 
The efficacy analyses of PFS and key secondary endpoints will be conducted on the full 
analysis set.  Treatment effects in efficacy endpoints will be evaluated and compared 
KdD vs Kd. 
In principle, summary statistics including mean, standard deviation, median, first and 
third quartiles, will be provided for continuous variables.  Frequency and percentage will 
be summarized by treatment arm for binary and categorical variables.  Proportions and 
the corresponding 95 CI will be based on normal approximations and the treatment 
comparison will be based on Cochran-Mantel-Haenszel test.  Exact tests will be 
considered for subgroup analyses when the cell size is considered small.  Time to-event 
endpoints will be estimated using the Kaplan-Meier (K-M) method.  Stratified log-rank 
test statistics and associated p-values will also be calculated.  Hazard ratios will be 
estimated using stratified Cox proportional hazards models. 
For PFS, response and disease progression will be determined by an IRC in a blinded 
manner.  In addition, response and disease progression outcomes will be determined 
locally by investigators in an unblinded manner and centrally by the sponsor using a 
validated computer algorithm (Onyx Response Computer Algorithm, ORCA) in a blinded 
manner.  The primary analysis of PFS will be based on IRC assessed outcomes; the 
timing will be event driven and will happen when approximately 188 PFS events are 
reached.  The PFS outcomes assessed by the investigators as well as by ORCA will 
serve as supportive analyses of PFS.

Protocol Number:  20160275 
Date:  17 March 2021

CONFIDENTIAL 
 
 
The primary comparison of PFS will be tested using a log rank test stratified by the 
randomization stratification factors per IxRS at 1-sided significance level of 0.025.  
Testing of the key secondary endpoints will be hierarchal in the order of ORR,  
MRD[-]CR, and OS such that the overall Type I error rate is strongly controlled under 
0.025 (1-sided).  Progression free survival, ORR, and MRD[-]CR will be tested at the 
PFS primary analysis, and OS will be tested at 
 and 
 analyses according to 
sequential testing order. 
The specific testing procedure for the primary and the key secondary endpoints is as 
follows: 
 
PFS (arm 1 vs arm 2) is tested at alpha level of 0.025 at the primary analysis 
 
If PFS is significant at the primary analysis, then ORR and MRD[-]CR are tested 
sequentially at alpha level of 0.025 
 
If PFS, ORR, and MRD[-]CR are all statistically significant, then OS will be tested 
multiple times with an overall alpha of 0.025. 
 
 
 
 
 
 
 
Further details of secondary endpoint testing will be described in the SAP. 
10.4.2 
Primary Efficacy Endpoint 
The primary comparison for PFS between arm 1 and arm 2 will use the log-rank test 
stratified by the randomization stratification factors per IxRS.  The HR (95 CI) will be 
estimated using a stratified Cox proportional hazards regression model as relative 
treatment effect.  The distribution of PFS including median will be summarized 
descriptively using the K-M method for each treatment group. 
The primary endpoint will be analyzed within each of the subgroups listed in 
Section 10.1.3.  Specifically, to determine whether the treatment effect is consistent 
across subgroups including, but not limited to, various geographical regions (eg, North 
America, Europe, Asia, and other), the estimate of the hazard ratios (with 95 CI) by 
Cox proportional hazards regression model for PFS between the treatment groups will 
be provided.  Additionally, a treatment-by-subgroup interaction test will be provided as 
appropriate.

10.4.3 
Secondary Efficacy Endpoint(s) 
If PFS is significant, the key secondary endpoints will be tested by sequential testing in 
the order of ORR, MRD[-]CR by NGS, and OS. 
The analysis for ORR and MRD[-]CR will be done if the primary analysis of PFS reaches 
statistical significance.  
The inferential comparison between treatment groups for both the ORR and MRD[-]CR 
will be made using the Cochran-Mantel-Haenszel chi-square test controlling for the 
randomization stratification factors per IxRS.  An estimate of the common odds ratio 
(95 CI) will be provided as a measure of the relative treatment effect.  The primary 
analysis of ORR will be based on IRC assessed outcomes.  The analyses based on 
investigator-assessed and ORCA will serve as supportive analyses.  Similarly, the CR 
portion of the MRD[-]CR endpoint will be based on IRC assessments. 
Overall survival will be analyzed using the same method as described for the PFS 
endpoints after PFS, ORR, MRD[-]CR all reach statistical significance.

In the case that the PFS results are not statistically significant at the primary PFS 
analysis, the sponsor may stop the study and if so, the subjects will not be followed for 
OS any further. 
For subgroups listed in Section 10.1.3, odds ratio (with 95 CI) will be provided for ORR 
and MRD[-]CR rate between the treatment groups.  A treatment-by-subgroup interaction 
test will be provided as appropriate. 
Subgroup analysis for OS will be performed using the same method described for PFS, 
as appropriate. 
10.4.4 
Safety Endpoints 
The analysis of safety endpoints will be based on the safety analysis set.  The number 
and percentage of subjects experiencing at least 1 adverse event will be summarized by 
treatment group, relationship of adverse event to study treatment, and severity.  Subject 
incidence of all treatment-emergent adverse events will be tabulated by system organ 
class and preferred term.  Laboratory parameters will be summarized using descriptive 
statistics, by postdose shifts relative to baseline, and a summary of subject incidence of 
clinically significant values.  Vital signs will be summarized by changes from baseline 
values for each treatment group using descriptive statistics.  The LVEF and FEV1/FVC 
endpoints will be summarized by changes from baseline values for each treatment group 
using descriptive statistics.  Drug exposure including duration and intensity will be 
summarized descriptively for each treatment group.

Subjects may be eligible for continued treatment with Amgen investigational product(s) 
by an extension protocol or as provided for by the local country’s regulatory mechanism.  
However, Amgen reserves the unilateral right, at its sole discretion, to determine 
whether to supply Amgen investigational product(s) and by what mechanism, after 
termination of the study and before the product(s) is/are available commercially. 
12.2 
Study Documentation and Archive 
The investigator is to maintain a list of appropriately qualified persons to whom he/she 
has delegated study duties.  All persons authorized to make entries and/or corrections 
on eCRFs will be included on the Amgen Delegation of Authority Form. 
Source documents are original documents, data, and records from which the subject’s 
eCRF data are obtained.  These include but are not limited to hospital records, clinical 
and office charts, laboratory and pharmacy records, diaries, microfiches, radiographs, 
and correspondence. 
Electronic CRF entries may be considered source data if the eCRF is the site of the 
original recording (ie, there is no other written or electronic record of data). 
The investigator and study staff are responsible for maintaining a comprehensive and 
centralized filing system of all study-related (essential) documentation, suitable for 
inspection at any time by representatives from Amgen and/or applicable regulatory 
authorities.   
Elements to include: 

Product:  Carfilzomib 
Protocol Number:  20160275 
Date:  17 March 2021

CONFIDENTIAL 
 
 
 
Subject files containing completed CRFs, ICFs, and subject identification list 
 
Study files containing the protocol with all amendments, Investigator’s Brochure, 
copies of prestudy documentation, and all correspondence to and from the IRB/IEC 
and Amgen 
 
Investigational product-related correspondence including Proof of Receipts (POR), 
Investigational Product Accountability Record(s), Return of Investigational Product 
for Destruction Form(s), Final Investigational Product Reconciliation Statement, as 
applicable 
 
Non-investigational product(s), and/or medical device(s) or combination product(s) 
documentation, as applicable 
In addition, all original source documents supporting entries in the eCRFs must be 
maintained and be readily available. 
Retention of study documents will be governed by the Clinical Trial Agreement. 
12.3 
Study Monitoring and Data Collection 
The Amgen representative(s) and regulatory authority inspectors are responsible for 
contacting and visiting the investigator for the purpose of inspecting the facilities and, 
upon request, inspecting the various records of the clinical study (eg, eCRFs and other 
pertinent data) provided that subject confidentiality is respected. 
The Clinical Monitor is responsible for verifying the eCRFs at regular intervals 
throughout the study to verify adherence to the protocol; completeness, accuracy, and 
consistency of the data; and adherence to local regulations on the conduct of clinical 
research.  The Clinical Monitor is to have access to subject medical records and other 
study-related records needed to verify the entries on the eCRFs. 
The investigator agrees to cooperate with the clinical monitor to ensure that any 
problems detected in the course of these monitoring visits, including delays in 
completing eCRFs, are resolved. 
In accordance with ICH GCP and the sponsor’s audit plans, this study may be selected 
for audit by representatives from Amgen’s Global Research & Development Compliance 
and Audit function (or designees).  Inspection of site facilities (eg, pharmacy, 
protocol-required therapy storage areas, laboratories) and review of study-related 
records will occur to evaluate the study conduct and compliance with the protocol, 
ICH GCP, and applicable regulatory requirements. 
Data capture for this study is planned to be electronic: 
 
All source documentation supporting entries into the CRFs must be maintained and 
readily available.

CONFIDENTIAL 
 
 
 
Updates to eCRFs will be automatically documented through the software’s “audit 
trail.” 
 
To ensure the quality of clinical data across all subjects and sites, a clinical data 
management review is performed on subject data received at Amgen.  During this 
review, subject data are checked for consistency, omissions, and any apparent 
discrepancies.  In addition, the data are reviewed for adherence to the protocol and 
GCP.  To resolve any questions arising from the clinical data management review 
process, data queries are created in the EDC system database for site resolution 
and subsequently closed by the EDC system or by an Amgen reviewer. 
 
The investigator signs only the Investigator Verification Form for this EDC study or 
the investigator applies an electronic signature in the EDC system if the study is set 
up to accept an electronic signature.  This signature indicates that investigator 
inspected or reviewed the data on the eCRF, the data queries, and agrees with the 
content. 
12.4 
Investigator Responsibilities for Data Collection 
The investigator is responsible for complying with the requirements for all assessments 
and data collection (including subjects not receiving protocol-required therapies) as 
stipulated in the protocol for each subject in the study.  For subjects who withdraw prior 
to completion of all protocol-required visits and are unable or unwilling to continue the 
Schedule of Assessments (Table 11), the investigator can search publically available 
records (where permitted) to ascertain survival status.  This ensures that the data set(s) 
produced as an outcome of the study is/are as comprehensive as possible.   
12.5 
Language 
Electronic CRFs must be completed in English.  TRADENAMES (if used) for 
concomitant medications may be entered in the local language.  Consult the 
country-specific language requirements. 
All written information and other material to be used by subjects and investigative staff 
must use vocabulary and language that are clearly understood.   
12.6 
Publication Policy 
To coordinate dissemination of data from this study, Amgen may facilitate the formation 
of a publication committee consisting of several investigators and appropriate Amgen 
staff, the governance and responsibilities of which are set forth in a Publication Charter.  
The committee is expected to solicit input and assistance from other investigators and to 
collaborate with authors and Amgen staff as appropriate as defined in the Publication 
Charter.  Membership on the committee (both for investigators and Amgen staff) does 
not guarantee authorship.  The criteria described below are to be met for every 
publication.

Authorship of any publications resulting from this study will be determined on the basis 
of the International Committee of Medical Journal Editors (ICMJE) Recommendations for 
the Conduct of Reporting, Editing, and Publications of Scholarly Work in Medical 
Journals, which states: 
 
Authorship credit should be based on (1) substantial contributions to conception and 
design, acquisition of data, or analysis and interpretation of data; (2) drafting the 
article or revising it critically for important intellectual content; (3) final approval of the 
version to be published; and (4) agreement 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.  Authors should meet conditions 1, 
2, 3, and 4. 
 
When a large, multicenter group has conducted the work, the group should identify 
the individuals who accept direct responsibility for the manuscript.  These individuals 
should fully meet the criteria for authorship defined above. 
 
Acquisition of funding, collection of data, or general supervision of the research 
group, alone, does not justify authorship. 
 
All persons designated as authors should qualify for authorship, and all those who 
qualify should be listed. 
 
Each author should have participated sufficiently in the work to take public 
responsibility for appropriate portions of the content. 
All publications (eg, manuscripts, abstracts, oral/slide presentations, book chapters) 
based on this study must be submitted to Amgen for review.  The Clinical Trial 
Agreement among the institution, investigator, and Amgen will detail the procedures for, 
and timing of, Amgen’s review of publications. 
12.7 
Compensation 
Any arrangements for compensation to subjects for injury or illness that arises in the 
study are described in the Compensation for Injury section of the Informed Consent that 
is available as a separate document. 
If permitted under applicable regional laws or regulatory guidelines, study subjects may 
be reimbursed for reasonable travel costs and other expenses directly related to 
participation in this clinical trial.

Appendix E.  Guidelines for Documenting Prior Treatment 
Patients must have documented relapse after at least 1, but no more than 3 prior 
treatment regimens or lines of therapy for multiple myeloma.  When documenting prior 
treatments for multiple myeloma, the following guidelines should be used: 
 
A new line of therapy is considered to start when a planned course of therapy is 
modified to include other treatment agents (alone or in combination) as a result of 
lack of adequate response, progressive disease (PD) (even if the level of 
progression has not yet met International Myeloma Working Group-Uniform 
Response Criteria [IMWG-URC] for PD), relapse, or toxicity. 
 
An increase in dose of therapy, with the intention of recapturing response in a patient 
who has evidence of progression on that therapy, is considered a new therapy. 
 
A new line of therapy is also considered to start when a planned period of 
observation off therapy is interrupted by a need for additional treatment for the 
disease. 
 
Examples of 1 line of therapy include: 
 
Induction therapy and stem cell transplant followed by planned maintenance 
therapy (provided there is no intervening PD) 
 
Induction therapy followed by maintenance therapy (provided there is no 
intervening PD) 
 
Documentation of at least partial response (PR) to at least 1 prior therapy 
 
For patients with prior carfilzomib therapy, documentation of response (  PR) must 
be available for the most recent previous carfilzomib therapy as well as stop date.  
Documentation that the patient was not removed from carfilzomib therapy due to 
toxicity must also be available.  For patients with prior therapy with either carfilzomib, 
the start of the 6-month treatment-free interval is when either carfilzomib is 
discontinued even if other portions of the regimen are continued.

CR  complete response; FLC  free light chain; MR  minimal response; PD  progressive disease; 
PR  partial response; sCR  stringent complete response; SFLC  serum free light chain; SPD  maximal 
perpendicular diameter; VGPR  very good partial response. 
All response categories (CR, sCR, VGPR, PR) require 2 consecutive assessments 
made at any time before the initiation of any new therapy as well as no known evidence 
of progressive or new bone lesions if radiographic studies were performed.  
Radiographic studies are not required to satisfy these response requirements.  Bone 
marrow, plasmacytoma, and skeletal survey assessments are not required to be 
confirmed by repeat testing.   
For sCR:  presence/absence of clonal cells is based upon the kappa lambda ratio.  An 
abnormal kappa lambda ratio by immunohistochemistry and/or immunofluorescence 
requires a minimum of 100 plasma cells for analysis.   
If patients do not have measurable disease at baseline, they can only be assessed for at 
least a CR or progressive disease (PD), otherwise they will be NE. 
Determination of PD while on study requires 2 consecutive assessments made at any 
time (no minimal interval is required, it can be done the same day; however, to confirm 
response or PD, 2 discrete samples are required) before classification of PD and/or the

institution of new therapy.  Confirmative samples for PD after new therapy can be used.  
Serum M-component increases of  1 g/dL from nadir are sufficient to define progression 
if nadir M-component is  5 g/dL. 
Plasmacytomas:  A definite increase in the size is defined as a  50 increase from 
nadir as measured serially by the sum of the products of the maximal perpendicular 
diameter (SPD) of the measurable lesion or a  50 increase in the longest diameter of 
a previous lesion with  1 cm short axis.  A plasmacytoma is considered measurable if 
the longest diameter is at least 1 cm and the product of the cross diameters is at least 
1 cm2.  Plasmacytomas of lesser size will be considered non-measurable.  The 
requirement for bi-directional measurements applies only to plasmacytomas.  The 
plasmacytoma specifications for PD are based on the sponsor’s interpretation of the 
IMWG-URC and practical considerations for study execution. 
For defining nadir, in the case where a value is felt to be a spurious result per 
physician/Independent Review Committee (IRC) discretion (eg, a possible laboratory 
error), that value will not be considered when determining the lowest value.

EudraCT Number 2016-003554-33 
NCT Number NCT03158688 
Amendment Date: 
17 March 2021 
 
Rationale: 
This protocol is being amended to include the following key changes: 
 
The maximum treatment duration for an individual study participant may be 
extended from 4 years to
 
to obtain additional long-term safety data per 
Food and Drug Administration Postmarketing Commitment. 
 
 
 
 as the primary endpoint for this study 
has been met.  Disease assessments will be performed locally per standard 
of care. 
 
 
. Only local laboratory testing will be utilized to monitor 
the safety of study participants to eliminate the logistic challenges at site 
including the risk of delayed lab kits as seen during the pandemic and reduce 
the volume of blood drawn from a study participant in excess of clinical need. 
 
Specified the timing and details regarding end of study to align with the safety 
reporting requirements for hepatitis B virus (HBV) reactivation in study 
participants receiving daratumumab. 
 
Adding new or clarifying recommended actions for carfilzomib dosage 
adjustments and/or treatment delays for nonhematologic toxicities, namely 
progressive multifocal leukoencephalopathy, renal dysfunction, tumor lysis 
syndrome, and thrombotic microangiopathy.

 
Adding changes for daratumumab intravenous infusion rates based on 
available clinical data (Barr et al, 2017).  Starting with cycle 2, daratumumab 
infusion may be shortened to a 90-minutes accelerated infusion for study 
participants who have received and well-tolerated the 2 prior doses of 
daratumumab standard infusion rates in cycle 1. 
 
Adding precautionary instructions that vaccination with live attenuated 
vaccines is not permitted at any time while the study participant is receiving 
study treatments due to the risk of being immunosuppressed. 
 
Removing bone marrow sample collection for minimal residual disease 
(MRD) assessments after the 
 (48 months after last 
subject enrollment [LSE]) OS DCO. After a minimum treatment duration of 
3 years, it is expected that the number of subjects achieving a complete 
response (CR) is low. In addition, all subjects with MRD[-]CR at 12 months 
landmark have surpassed the MRD collection timepoint for the secondary 
endpoint persistence of MRD[-]CR. Therefore, omitting MRD assessments 
after 
 will not have an impact on previously reported 
MRD outcomes. 
 
To clarify that the Data Monitoring Committee (DMC) will not meet beyond 
the primary analysis. 
 
Removing Clinical Outcome Assessments based on the available data. At the 
primary analysis, a slightly higher health-related Quality of Life was 
associated with 20/56 mg/m2 twice weekly carfilzomib, dexamethasone, and 
daratumumab (KdD), however it was maintained with both KdD and 
20/56 mg/m2 twice weekly carfilzomib and dexamethasone (Kd) treatments.  
Updated analysis at 
 Analysis did not show any new findings 
and it is expected that the difference will continue to be low. 
 
Removing the pregnancy test at the follow-up visit 30 (+3) days after the last 
dose of all study drugs for females of childbearing potential (FCBP). 
 
Removing reference to daratumumab interference testing aimed to mitigate 
the risk of underreporting treatment response of complete response. The key 
secondary endpoint ORR was met at the primary analysis. In addition, 
~ 36 months from LSE, the overall incidence of patients achieving a best 
response of CR is considered low. 
 
Removing daratumumab pharmacokinetics (PK) and anti-Dara antibody 
(ADA) sample collection at Follow up Visit 2 (8 weeks after the last dose of 
daratumumab) including the instructions that subjects with evidence of 
positive anti-drug antibody levels need to be followed until they return to 
baseline.  At present, daratumumab PK data was collected from 
approximately 2/3 of patients and analysis has shown that carfilzomib has no 
observable effect on daratumumab PK. In addition, no patient showed 
evidence of ADA positivity. Consistent with the overall low incidence of 
anti-Dara antibodies across studies (< 1%) the expected ADA rate will 
continue to be low and review of clinical data from antibody-positive subjects 
did not identify any new safety concerns or meaningful impact on efficacy.

Removing the Follow up Visit 2 from the Schedule of Activities resulting from 
changes with regards to daratumumab PK and ADA sample collection. 
Adding medical device use, serious adverse event, and safety monitoring 
plan language per updates to the Amgen protocol template. 
 
Removing Investigational Product Instruction Manual (IPIM) language per 
updates to the Amgen protocol template.

Amendment 1 
Protocol Title:  A Randomized, Open-label, Phase 3 Study Comparing Carfilzomib, 
Dexamethasone, and Daratumumab to Carfilzomib and Dexamethasone for the 
Treatment of Patients With Relapsed or Refractory Multiple Myeloma 
 
Amgen Protocol Number (carfilzomib) 20160275 
EudraCT number 2016-003554-33 
 
Amendment Date: 
15 February 2017 
 
Rationale: 
This protocol is being amended to: 
• 
Include safety objectives and endpoints as additional secondary objectives and 
endpoints 
• 
Clarify that the evaluation of CR (for key secondary endpoint) will be based on IRC 
assessment 
• 
Clarify that the original International Staging System (ISS) will be used in this study 
to stratify subject (as opposed to the revised ISS) 
• 
 
 
 
. 
• 
Update and clarify the International Uniform Response Criteria for Multiple Myeloma 
• 
Update and clarify language in subject eligibility criteria based on regulatory agency 
and steering committee feedback 
• 
Add additional exclusion criteria in order to maintain consistency with dose 
modification table and to clarify the minimal requirements for subjects that have 
undergone an allogeneic transplant 
• 
Update study schema with a footnote regarding subjects with baseline chronic 
hepatic impairment 
• 
Clarify the actual expected dose for subjects that have baseline chronic (mild, 
moderate) hepatic impairment 
• 
Include requirements for prehydration for subjects treated with carfilzomib 
• 
Update language regarding dosage adjustments, delays, rules for withholding or 
restarting, or permanent discontinuation of carfilzomib to reflect the range of 
management options available to investigators in case of toxicity 
• 
Update language to allow for possible re-escalation of carfilzomib dose under certain 
conditions

• 
Update treatment guidelines for nonhematologic toxicities: 
− 
Add guidelines for chronic dialysis base on results from Study CFZ001 
− 
Clarify the parameters for holding carfilzomib during the treatment of an infection 
− 
Add guidance to investigate cause of dyspnea 
− 
Add guidance for lower grade hypertension 
− 
Language reworded for clarity 
• 
Clarify timing of pulmonary function tests in relation to daratumumab infusion 
• 
Remove total protein from laboratory analyte table as this is duplicated in the 
required serum protein electrophoresis needed for disease assessment 
• 
Add DLCO assessment to allow for identification of diffusion abnormalities and in 
some cases to support the diagnosis of other lung diseases such as pulmonary 
hypertension 
• 
Add language regarding the use of local laboratory results to be applied to screening 
requirements in cases where central laboratory is unable to provide these results 
• 
Remove magnetic resonance imaging (MRI) from bone lesion assessment as X-ray, 
CT, or PET-CT are more appropriate in the monitoring of these lesions 
• 
Update list of countries participating in global study 
• 
Generally clarify language throughout the protocol for better readability 
• 
Address typographical, grammatical, and formatting issues throughout the protocol
