Study design: 
This is an open-label, multicenter, Phase 1b, dose-finding study of carfilzomib 
administered once weekly in combination with lenalidomide and dexamethasone (KRd).  
Once-weekly carfilzomib in a KRd regimen will be evaluated in RRMM and NDMM 
subjects.   
There will be 2 parts in the study: Dose Evaluation and Dose Expansion.   
Prior to protocol amendment 2
Two dose levels of once-weekly carfilzomib in a KRd regimen (Cohort 1 and Cohort 2) 
will be evaluated during the Dose-evaluation Component in RRMM subjects; a third 
optional KRd regimen (with a reduced dose level of lenalidomide) may also be evaluated 
(Cohort 3).  Approximately 8 dose-limiting toxicity (DLT) evaluable RRMM subjects 
will be enrolled into each opened Dose-evaluation cohort.   
: 
The second part is the Dose-expansion Component during which approximately  
60 subjects (30 RRMM and 30 NDMM subjects) will receive the KRd regimen selected 
in the Dose-evaluation Component. 
Per protocol amendment 2
NDMM subjects will be enrolled into an additional Dose-evaluation Cohort 4.  
Approximately 8 DLT-evaluable subjects will be treated with carfilzomib given once 
weekly with 2-step-up dosing in a KRd regimen.  The Cohort Safety Review Committee 
(CSRC) may then elect to open enrollment to a Dose-expansion Component for an 
additional 30 NDMM subjects.  
: 
Subjects may continue to receive study treatment for up to 18 cycles.  Newly diagnosed 
multiple myeloma subjects may interrupt therapy after cycle 4 for autologous stem cell 
transplant (ASCT).   
All subjects will be evaluated for safety at an End of Treatment (EOT) visit, 28 ± 7 days 
after the last study treatment, and with an EOT echocardiogram (ECHO), done within 
28 ± 7 days after the last study treatment.  
Following the EOT, subjects who have not had disease progression or allogeneic stem 
cell transplant will enter Active Follow-up.   
Number of 
investigational 
sites: 
Approximately 30 sites 
Planned number 
of subjects: 
Approximately 114 subjects in total.  
Prior to protocol amendment 2, 56 RRMM and 20 NDMM subjects were enrolled in the 
study.  Twenty-two RRMM subjects were enrolled into the RRMM Dose-evaluation 
Component; 34 RRMM subjects were enrolled into the RRMM Dose-expansion 
Component of the study.  Enrollment of RRMM subjects is completed. 
Per protocol amendment 2
NDMM subjects enrolled prior to protocol amendment 2 who are DLT-evaluable at 
Cohort 4 dosing will be considered Cohort 4 subjects. 
, approximately 38 NDMM subjects will be enrolled in the 
study: approximately 8 subjects will be enrolled into the NDMM Dose-evaluation 
Component, and approximately 30 subjects will be enrolled in the second NDMM 
Dose-expansion Component of the study. 
Sample size 
justification: 
Sample sizes are determined to provide preliminary information on safety, clinical 
activity, PDn, and PK.  With respect to safety, 38 subjects with relapsed disease in the 
dose cohort selected to move into the expansion component and 38 NDMM subjects will 
allow an approximately 86% probability to detect an occurrence of an adverse event 
(AE) with 5% incidence rate.   
Study population: 
Subjects with relapsed multiple myeloma who have received 1 to 3 prior lines of therapy 
and subjects with newly diagnosed, transplant-eligible or transplant-ineligible multiple 
myeloma.

Treatment and 
assessments: 
Treatment cycles are 28 days in duration and consist of KRd combination treatment as 
described above. 
 
 
Criteria for evaluation: 
Safety 
variables: 
Safety and tolerability will be assessed by incidence and severity of AEs and changes 
from baseline of all relevant parameters, including laboratory values, vital signs, 
electrocardiogram (ECG), and ECHO.  Severity of AEs will be assessed according to the 
National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events 
(CTCAE; version 4.03).  All subjects will be monitored for AEs for 30 days after the last 
administration of study treatment.   
Efficacy 
variables: 
Disease assessments according to the IMWG-Uniform Response Criteria (URC) will be 
conducted at Screening (within 21 days before dosing on Cycle 1 Day 1) and then at 
Cycle 2 Day 1 and on Day 1 ± 3 days of every cycle thereafter for up to 18 cycles.  
Minimal residual disease (MRD) status will be assessed by using flow cytometry (FC) of 
cell surface markers and Next Generation Sequencing (NGS) of DNA and/or RNA from 
the Ig locus.  The MRD analysis by FC will be performed on bone marrow aspirated at 
2 time points:  Cycle 8 Day 1, and upon achieving a CR or sCR.  The MRD analysis by 
NGS will be performed using blood and bone marrow aspirates collected at 3 time points:  
baseline, Cycle 8 Day 1, and upon achieving a CR or sCR. 
PK: 
For both the Dose-evaluation and the Dose-expansion Components, blood samples will be 
collected from all subjects on Day 8 of Cycle 1 for determination of plasma 
concentrations of carfilzomib.  On the day of blood collection, blood will be collected at 
predose, 15 minutes after the start of the infusion, immediately prior to (within 2 minutes 
before) the end of the infusion, and 15 and 60 minutes after the end of the infusion. 
PDn: 
Whole blood will be collected from all subjects in the Dose-evaluation Component, and 
the first 8 subjects enrolled in Dose-expansion Arm 3, on Days 1, 8, 9, and 11 of 
Cycle 1.  On Days 1 and 8 of Cycle 1 whole blood will be collected pre-carfilzomib dose 
and post-carfilzomib dose.  On Days 9 and 11 of Cycle 1, when carfilzomib is not 
administered, one PDn sample will be collected at approximately the same time as when 
the pre-infusion sample was taken on Day 8. 
 
Genomics: 
Analysis of genetics, gene expression, and cell surface biomarkers that may predict for 
response and resistance to treatment with proteasome inhibitors will be performed.  
Exploratory studies will be conducted on all subjects who consent to optional genomic 
biomarker analysis.  These analyses will be performed on bone marrow aspirate (the 
remaining portion of the bone marrow aspirate sample left after the amount required for 
fluorescent in situ hybridization (FISH) analysis has been collected at baseline), as well as 
a sample of blood and saliva also collected at the time of baseline.  At progression, an 
optional additional bone marrow sample for biomarker analysis may be collected from all 
subjects who consent. 
Whole genome sequencing (WGS), whole exome sequencing (WES), whole transcriptome 
sequencing (RNA-Seq), and/or other methods of nucleic acid and protein quantification 
will be conducted on isolated tumor (CD138+) cells from these bone marrow aspirate 
samples.  In addition, WGS or WES will be performed on a normal tissue sample (eg, 
CD3+ T cells isolated from peripheral blood or saliva) to distinguish germ line mutations 
from somatic mutations in tumor cell samples. 
Other: 
Subject convenience and satisfaction with the carfilzomib dosing schedule will be 
assessed by questionnaire at Cycle 3 Day 1 and Cycle 18 Day 1. 
Statistical 
methods and 
analyses: 
All safety and efficacy analyses will be based upon the Safety Population, defined as 
subjects receiving treatment with at least 1 dose of carfilzomib.  In addition, response data 
(overall response rate [ORR], complete response rate [CRR], progression-free survival

Statistical 
methods and 
analyses 
(cont’d): 
[PFS], duration of response [DOR]) may also be analyzed based on the 
Response-evaluable Population, defined as subjects who are included in the Safety 
Population, have a baseline disease assessment and at least 1 postbaseline disease 
assessment, or dropped out due to AE prior to the first postbaseline disease assessment. 
Primary Endpoints
• 
Safety and tolerability of carfilzomib administered once weekly in combination 
with lenalidomide and dexamethasone, as defined by the type, incidence, and 
severity of AEs, and changes from baseline in key laboratory analyses, 
including immunoglobulin levels, vital signs, and the extent and duration of 
exposure to study drugs.   
: 
All treatment-emergent AEs will be summarized by Medical Dictionary for 
Regulatory Activities (MedDRA) preferred term, NCI CTCAE grade, and 
investigator assessment of causality.  In addition, all serious adverse events 
(SAEs), including deaths, will be listed separately.  Extent of exposure to the 
study treatment will be summarized using descriptive statistics.  Laboratory 
parameters will be summarized using descriptive statistics and by postdose 
shifts relative to baseline.  Vital signs will also be summarized descriptively for 
each scheduled protocol time point.   
Secondary Endpoints
• 
Pharmacokinetics (PK) of carfilzomib 
: 
• 
Overall Response Rate (ORR), defined as the proportion of subjects who 
achieve a best overall response of stringent complete response (sCR), CR, very 
good partial response (VGPR), or PR in accordance with IMWG-URC  
• 
Complete Response Rate (CRR), defined as the proportion of subjects who 
achieve a best overall response of either sCR or CR in accordance with 
IMWG-URC  
• 
Progression-free Survival (PFS), defined as the time from the first day of study 
treatment to the earlier of disease progression or death due to any cause  
• 
Duration of Response (DOR), defined as the time from the first evidence of 
confirmed PR or better to disease progression or death due to any cause among 
subjects who respond  
Point estimates for ORR and CRR along with their exact 2-sided 95% confidence intervals 
will be calculated.  The distribution of time-to-event endpoints (PFS and DOR) will be 
summarized descriptively using the Kaplan-Meier method.   
Safety and efficacy analyses will be performed by dose levels and by populations (newly 
diagnosed and relapsed). 
Pharmacokinetics
The PK parameter estimates for carfilzomib will be summarized, including total plasma 
exposure (expressed as area under the curve; AUC), maximum plasma concentration 
(Cmax), time to maximum plasma concentration (Tmax), total plasma clearance, and plasma 
terminal half-life (as appropriate for data collected).  Estimates for these parameters will 
be tabulated and summarized (ie, mean, standard deviation).  The PK parameters will be 
summarized descriptively.

Exploratory Endpoints
• 
Pharmacodynamics (PDn) of proteasome inhibition by carfilzomib measured in 
whole blood 
: 
• 
MRD[-] rate, defined as the proportion of subjects who have negative MRD at 
Cycle 8 Day 1.  Point estimates for MRD[-] rate along with exact 2-sided 95% 
confidence intervals will be calculated for both MRD assessment methods   
• 
Subject convenience and satisfaction with the carfilzomib dosing schedule.   
• 
WGS, WES, whole transcriptome sequencing, and other nucleic acid and 
protein quantification data and immunoglobulin levels in tumor cells

WGS, WES, RNA-Seq, and/or other nucleic acid and protein quantification data will be 
analyzed to characterize whether drug response is related to alterations in genes regulated 
by or involved in activation of nuclear factor kappa light chain enhancer of activated B 
cells (NF-Kappa B) transcription factors as well as in genes involved in immunoglobulin 
production and protein homeostasis.  Immunoglobulin levels in tumor cells will be 
quantified by enzyme-linked immunosorbent assay (ELISA) and/ or other protein 
quantification methods.  The genomic data as a whole will also be used to derive new 
hypotheses about mechanisms of drug response, resistance, and safety.

INTRODUCTION 
BACKGROUND INFORMATION 
Kyprolis (Carfilzomib for Injection [carfilzomib]) is a proteasome inhibitor that received 
accelerated approval from the United States (US) Food and Drug Administration (FDA) in 
July 2012 for the treatment of patients with multiple myeloma who have received at least 2 
prior therapies, including bortezomib and an IMiD and have demonstrated disease 
progression on or within 60 days of completion of the last therapy.  The approval was based 
on the results of the Study PX-171-003 – Part 2 (A1) in 266 subjects with relapsed and/or 
refractory multiple myeloma.  Subsequent full approval in the US and European Union was 
based on two 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 and refractory 
multiple myeloma (RRMM). 
The study detailed in the current protocol will evaluate several dose levels of carfilzomib in 
combination with lenalidomide and dexamethasone.   
RRMM and newly diagnosed multiple myeloma (NDMM) subjects will be treated with 
carfilzomib given once weekly in combination with lenalidomide (Revlimid) and 
dexamethasone as part of a carfilzomib (K), lenalidomide (R) and dexamethasone (d) 
regimen (KRd).  Carfilzomib will be given as a 30-minute infusion once weekly for the first 
3 weeks of a 4-week (28-day) cycle as part of a KRd regimen.   
This study will evaluate the safety and tolerability of once-weekly carfilzomib regimens in 
subjects with relapsed multiple myeloma or newly diagnosed multiple myeloma.   
3.2 
MULTIPLE MYELOMA 
Multiple myeloma, a clonal neoplastic proliferation of plasma cells, is the second most 
common hematologic malignancy and is responsible for approximately 72,000 annual deaths 
worldwide (Ferlay 2010).  There are an estimated 11,000 deaths per year in the US and more 
than 19,000 deaths per year in Europe (American Cancer Society 2014; Boyle 2005).  
Multiple myeloma is characterized by anemia, bone destruction, monoclonal gammopathy,

Clinical Study Protocol No. CFZ013

CONFIDENTIAL 
renal failure, hypercalcemia, and increased susceptibility to infections.  The disease is 
systemic and chemotherapy is indicated for management of symptomatic myeloma.   
Current treatment options for people with newly diagnosed multiple myeloma commonly 
include combination chemotherapy with regimens consisting of melphalan (Alkeran), 
bortezomib (Velcade), thalidomide (Thalomid), and lenalidomide (Revlimid) with or without 
corticosteroids such as dexamethasone or prednisone.  For people whose tolerance is not 
limited by age or co-morbidities, the preferred treatment is standard chemotherapy or VRd 
followed by high dose, myeloablative chemotherapy and autologous stem cell 
transplantation (ASCT).  
Despite improvements in progression-free survival (PFS) and overall survival (OS) over the 
past 15 years, essentially all patients eventually relapse even with the best available approved 
treatments.   
3.3 
NOVEL THERAPIES FOR MULTIPLE MYELOMA 
3.3.1 
PROTEASOME BACKGROUND 
Proteasome inhibition has emerged as an important therapeutic strategy in multiple myeloma 
(Moreau 2012).  The proteasome is a multicatalytic proteinase complex that is responsible for 
degradation of a wide variety of protein substrates within normal and malignant 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.  
3.3.2 
CARFILZOMIB BACKGROUND (NONCLINICAL) 
Carfilzomib is a tetrapeptide epoxyketone-based inhibitor of the chymotrypsin-like activity 
of the 20S proteasome.  It is structurally and mechanistically different from the dipeptide 
boronic acid proteasome inhibitor bortezomib and showed less off-target activity when 
measured against a broad panel of proteases including metallo-, aspartyl-, and serine 
proteases compared to bortezomib; the latter showed off-target inhibitory activity in the 
nanomolar range against several serine proteases (Arastu-Kapur 2009).  This selectivity may 

Onyx Therapeutics, Inc. 
Clinical Study Protocol No. CFZ013 
Carfilzomib 
Page 23 of 108 
CONFIDENTIAL 
be responsible for the reductions in myelosuppression and neuropathy observed in 
nonclinical studies comparing carfilzomib with bortezomib. 
Based upon in vitro and in vivo studies, it is anticipated that a more intense and sustained 
proteasome inhibition can be achieved with carfilzomib relative to bortezomib, resulting in 
enhanced antitumor activity.  Continuous 72-hour exposure to carfilzomib was associated 
with potent cytotoxic and pro-apoptotic activity across a broad panel of tumor-derived cell 
lines in culture (Demo 2007).  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.  Carfilzomib was also 
cytotoxic in bortezomib-resistant tumor cell lines (Suzuki 2011; Kuhn 2007). 
Nonclinical studies in rats and monkeys have been performed administering carfilzomib IV 
for 5 consecutive days followed by 9 days of rest for 2 cycles.  Proteasome inhibition of more 
than 80% was achieved, suggesting that high-level inhibition of the proteasome with the 
epoxyketone class is possible, affording new opportunities to escalate dose to optimize 
antitumor effects (Yang 2011).  This finding was in contrast to nonclinical testing with the 
boronate class of inhibitors that prohibited uninterrupted daily dosing due to substantial 
morbidity and mortality.  Carfilzomib has also been administered to rats and monkeys for 6 
and 9 months, respectively (once daily × 2:  once daily dosing for 2 consecutive days 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 (current Carfilzomib Investigator’s Brochure [IB]).  In 
contrast, rats and monkeys treated with bortezomib in chronic toxicity studies were shown to 
have reduced motor activity, convulsions, tremors, and hind-limb paralysis accompanied by 
histological degeneration in peripheral nerves, as well as significant neutropenia (Velcade 
[bortezomib] full prescribing information [Millennium Pharmaceuticals 2012]; Velcade 
Summary of Product Characteristics [SmPC] 2012 [High Wycombe, Bucks, UK 2012]). 
3.3.3 
CARFILZOMIB BACKGROUND (CLINICAL) 
Carfilzomib entered clinical studies in September 2005.

Clinical Study Protocol No. CFZ013 
Carfilzomib 
Page 24 of 108 
CONFIDENTIAL 
As of 10 July 2016, an estimated 4833 subjects and 4114 subject-years have been exposed to 
carfilzomib in clinical trials conducted by Onyx Therapeutics, Inc. since the beginning of the 
development program.   
Carfilzomib has been administered on 2 consecutive days weekly for 3 weeks in a 28-day 
cycle in most studies conducted to date.   
Study PX-171-006 was the first to explore the option of combination therapy using 
carfilzomib and lenolidamide (the IMiD most widely employed for the treatment of multiple 
myeloma; Wang 2013).  This investigation was the model for another Phase 2 study of the 
carfilzomib, lenalidomide, dexamethasone (KRd) combination conducted by the Multiple 
Myeloma Research Consortium, and it used a maximum planned dose of 36 mg/m2 twice 
weekly in patients with newly diagnosed multiple myeloma (Jakubowiak 2012).  The Phase 3 
ASPIRE study compared the efficacy of KRd versus lenalidomide and dexamethasone alone 
in a much larger trial that enrolled 792 RRMM subjects.  ASPIRE showed an improved 
overall response rate and PFS with KRd therapy and provides a strong incentive to optimize 
the KRd regimen (Stewart 2015).  
The Phase 1/Phase 2 CHAMPION 1 trial of subjects with relapsed or progressing multiple 
myeloma who had received 1 to 3 prior regimens evaluated the safety and efficacy of 
carfilzomib administered once weekly at doses higher than the 56 mg/m2 maximum tolerated 
dose (MTD) previously established for the twice-weekly administration routine 
(Berenson 2016).  All subjects received carfilzomib (20 mg/m2) on Cycle 1 Day 1 but 
received the cohort-assigned test dose on Cycle 1 Days 8 and 15.  Testing started at 
45 mg/m2 in the first cohort and was escalated to 56, 70, and 88 mg/m2 in successive cohorts 
until the MTD was determined.  Subjects received dexamethasone 40 mg (IV or orally) on 
Days 1, 8, 15, and 22 of Cycles 1 through 8 and on Days 1, 8, and 15 from Cycle 9 onward. 
No dose-limiting toxicities (DLTs) were observed during dose escalation in the cohorts at 45, 
56, or 70 mg/m2.  At a carfilzomib dose of 88 mg/m2, 2 DLTs were observed during Cycle 1:  
Grade 3 dyspnea (Days 9–11) and Grade 3 vomiting (Day 15).  Therefore, the MTD of 
once-weekly carfilzomib in combination with dexamethasone was determined to be

Clinical Study Protocol No. CFZ013 
Carfilzomib 
Page 25 of 108 
CONFIDENTIAL 
70 mg/m2; a total of 104 subjects were treated at 70 mg/m2 carfilzomib dose level on the 
phase 1/2 CHAMPION-1 study. 
Five treatment-emergent serious adverse events (SAEs) were reported.  One subject had 
2 treatment-emergent SAEs (Grade 3 increased blood creatinine and Grade 4 hyponatremia), 
1 subject had Grade 3 pneumonia, 1 subject had Grade 3 dyspnea, and 1 subject had Grade 3 
chronic obstructive pulmonary disease.  The Grade 3 dyspnea event occurred in a subject 
receiving 88 mg/m2 carfilzomib and was considered to be related to carfilzomib treatment.  
All other SAEs were determined to be unrelated to carfilzomib or dexamethasone treatment.  
The treatment regimen showed promising efficacy with an overall response rate (ORR) of 
81% and a clinical benefit rate (CBR) of 93% (Berenson 2016), raising the question of 
whether weekly carfilzomib administered in combination with other antimyeloma agents 
might provide even greater patient benefit.  
3.3.4 
COMBINATIONS OF IMMUNOMODULATORY AGENTS AND 
PROTEASOME INHIBITORS  
Nonclinical studies showing that the IMiD lenalidomide sensitizes multiple myeloma cells to 
the proteasome inhibitor bortezomib suggested that combination therapy may enhance 
clinical activity (Mitsiades 2002).  The treatment paradigm involving proteasome inhibitor, 
immunomodulatory agent, and dexamethasone now forms the core of other treatment 
approaches aimed at improving either efficacy or tolerability (Kumar 2010).  The results of 
selected trials of proteasome inhibitors, lenalidomide and dexamethasone in subjects with 
multiple myeloma are summarized in Table 1.

These studies demonstrated the efficacy of regimens that combine lenalidomide with 
proteasome inhibitors (bortezomib or carfilzomib).  The regimens are effective and well 
tolerated both in patients newly with diagnosed multiple myeloma as well as those who have 
relapsed.   
3.4  
DOSE RATIONALE 
The dose rationale for this study derives from considerations of carfilzomib, lenalidomide, 
and dexamethasone dose combinations that are currently in use, as shown in Table 1.  Dose 
combinations for this study are shown in Table 2.  Prior to protocol amendment 2, 
dose-evaluation cohorts were planned only for RRMM subjects (Cohorts 1, 2, and 3).  
Schemas for enrollment prior to protocol amendment 2 are shown in Appendix E (Figure 2 
and Figure 3).  With protocol amendment 2, a Dose-evaluation cohort is added for NDMM 
subjects.   
The initial dosing for the proposed weekly KRd combinations (Cohorts 1, 2, and 3) in this 
study reflects a triangulation of the individual components of the studies listed in 
Cohorts 1, 2, and 3 
Table 1.  
The Dose-evaluation Component of the study begins with carfilzomib 56 mg/m2, 
lenalidomide 25 mg, and dexamethasone 40 mg in RRMM subjects  
(Cohort 1, Table 2).  As shown in Table 1, carfilzomib, in combination with dexamethasone, 
has been administered at weekly doses as high as 70 mg/m2/day given once weekly and 
56 mg/m2 given on 2 consecutive days (total weekly exposure of 112 mg/m2).  Carfilzomib 
given as part of a KRd regimen has been administered safely at doses as high as 36 mg/m2 
given on 2 consecutive days each week (total weekly exposure of 72 mg/m2).  Of note, no 
DLTs were identified at this dose in the Phase 1 study; dose escalation was stopped at 
36 mg/m2 twice-weekly because it was the maximum dose planned in the protocol.  The 
safety information from these trials supports a starting dose for Cohort 1 of carfilzomib 
56 mg/m2, lenalidomide 25 mg, and dexamethasone 40 mg.

A 2-step-up KRd regimen will be evaluated in NDMM subjects: carfilzomib will be given at 
20 mg/m2 on Day 1 of Cycle 1, 56 mg/m2 on Days 8 and 15 of Cycle 1, then 70 mg/m2 on 
Days 1, 8, and 15 beginning with Cycle 2 (Cohort 4; 
Cohort 4 
Table 2).  This regimen was selected by 
the Cohort Safety Review Committee (CSRC) for Dose-evaluation in NDMM subjects, after 
the occurrence of 2 SAEs in NDMM subjects during Cycle 1 of treatment at Cohort 2 dose-
level (Arm 1).

STUDY RATIONALE 
Exploration of therapeutic variations aimed at improving tolerance, patient convenience, 
efficacy, and treatment adherence are important considerations for treatment outcomes.  A 
study comparing routes of bortezomib administration showed no loss of efficacy with the 
more convenient subcutaneous (SC) route relative to that seen with the established IV route 
of administration (Moreau 2011).  Likewise, twice-weekly bortezomib IV administration was

used in the early trials of this agent (Richardson 2009).  A later study comparing 
once-weekly with twice-weekly bortezomib administration demonstrated improved safety, in 
particular a reduction in the rate of peripheral neuropathy, with no apparent effect on efficacy 
(Bringhen 2010). 
The combination of carfilzomib (twice-weekly), lenalidomide, and dexamethasone is a 
highly efficacious regimen in RRMM and NDMM subjects (Stewart 2015; Jakubowiak 2012; 
Korde 2013).  Of specific note, 23 of 26 subjects who reached nCR/CR achieved negative 
minimal residual disease (MRD[-]) status in one study (Jakubowiak 2012), while in another 
trial 27 of 27 subjects who reached nCR/CR achieved MRD[-] status (Korde 2013), further 
emphasizing the efficacy of this combination.  A favorable safety profile and promising 
preliminary efficacy for once-weekly carfilzomib in RRMM subjects was observed in the 
CHAMPION 1 study (Berenson 2016).   
This study will explore the safety and tolerability of once-weekly carfilzomib administered 
with lenalidomide and dexamethasone as part of a KRd regimen for RRMM and NDMM 
subjects.  Once-weekly carfilzomib is expected to improve tolerance, convenience, and 
treatment adherence.  The results will help inform decisions on future efficacy studies 
involving once-weekly carfilzomib administration.

EXPLORATORY OBJECTIVES 
Exploratory objectives include:  
• To explore the genomic and transcriptional biomarkers that might predict response and 
resistance to a once-weekly KRd regimen 
• To characterize the pharmacodynamics (PDn) of proteasome inhibition with a 
once-weekly KRd regimen in RRMM and NDMM subjects 
• To assess MRD status with a once-weekly KRd regimen in RRMM and NDMM subjects 
• To assess subject convenience and satisfaction with a once-weekly KRd regimen using 
subject questionnaire in RRMM and NDMM subjects

This is an open-label, multicenter, Phase 1b, dose-finding study of carfilzomib administered 
once-weekly in combination with lenalidomide and dexamethasone (KRd) in 28-day cycles 
to subjects with multiple myeloma.   
STUDY DESIGN 
Subjects may continue to receive study treatment for up to 18 cycles or until 1 or more of the 
following events occurs: 
• Disease progression 
• Allogeneic stem cell transplant 
• Withdrawal from the study for any reason 
• Study termination by the sponsor 
• Death 
Disease assessments will be conducted at Screening (within 21 days before dosing on 
Cycle 1 Day 1) and then on Day 1, ± 3 days, of every cycle beginning with Cycle 2.  
Response will be evaluated using the International Myeloma Working Group (IMWG) - 
Uniform Response Criteria (URC; Rajkumar, 2011; Appendix C).   
NDMM subjects may interrupt study treatment to proceed to hematopoietic stem cell 
collection, or stem cell collection and ASCT.  The investigator will communicate transplant 
plans with the clinical study team.  Upon completion of collection, subjects may resume 
study treatment (for up to the total of 18 cycles).  Study treatment interruption for autologous 
hematopoietic stem cell collection may not exceed 42 days.  Subjects with interruptions 
longer than 42 days may resume therapy on trial only with the written permission of the

sponsor study medical monitor.  Subjects may interrupt study treatment and proceed to 
ASCT at any time after Cycle 4.  Subjects who undergo ASCT may resume study treatment 
at any time up to posttransplant day 100, as elected by the investigator.   
There will be 2 parts in the study.   
The first part is the Dose-evaluation Component during which carfilzomib combination 
regimens will be evaluated (Table 2 and Figure 1).  Approximately 8 dose-limiting toxicity 
evaluable subjects will be enrolled into each opened Dose-evaluation cohort.  Before opening 
Dose-expansion arms, it must be determined that there are not more than 2 dose-limiting 
toxicities in 8 DLT-evaluable subjects at the dose selected for Dose-expansion.  
Dose-expansion arms may open once all safety data for at least 1 cycle at maximal dose 
carfilzomib is reviewed by the CSRC.   
The second part is the Dose-expansion Component.  
Prior to protocol amendment 2, dose evaluation was performed on RRMM subjects treated at 
Cohort 1 and Cohort 2 dosing (Table 2).  Cohort 2 dosing was selected for expansion with a 
plan for approximately 30 RRMM subjects and 30 NDMM subjects to be treated in the 
Dose-expansion Component (Arms 1 and 2; Appendix E; Figure 2 and Figure 3).   
In the first 8 NDMM subjects treated in Dose-expansion Arm 1 at Cohort 2 dosing, 2 SAEs 
were observed during Cycle 1 (Table 2).  Thus, with protocol amendment 2, Dose-evaluation 
Cohort 4 is added for NDMM subjects (Table 2 and Figure 1).  A Dose-expansion arm for 
NDMM subjects may open once all safety data for at least 1 cycle at maximal planned 
carfilzomib dose is reviewed by the CSRC as described in Section 5.4.   
All subjects will be evaluated for safety at an End of Treatment (EOT) visit, 28 ± 7 days after 
the last study treatment, and with an EOT echocardiogram (ECHO), done within 28 ± 7 days 
of the last study treatment.  The EOT visit will include a pregnancy test for females of 
childbearing potential (FCBP).  Following the EOT, subjects who have not had disease 
progression or allogeneic stem cell transplant will enter Active Follow-up.  For details 
regarding Active Follow-up, please refer to Section 5.6.

Prior to protocol amendment 2, subjects with newly diagnosed, previously untreated multiple 
myeloma were included only in the Dose-expansion Component 
(Appendix E; Figure 2, Arm 1).  After protocol amendment 2, NDMM subjects will be 
enrolled into a NDMM Dose-evaluation cohort, which may be expanded after safety 
evaluation by the CSRC (Arm 3, Figure 1).  
Complete eligibility criteria are described in Section 6. 
5.2 
DEFINITION OF DOSE-LIMITING TOXICITY 
Dose-limiting toxicity (DLT) of the KRd regimens will be evaluated during Cycle 1 
(Cohorts 1, 2, and 3), or Cycles 1 and 2 (Cohort 4), of the Dose-evaluation Component.   
Subjects in the Dose-evaluation Component of the study who do not complete the dose 
evaluation period for reasons unrelated to toxicity will be considered unevaluable for DLT 
and may be replaced.  DLT are the toxicities defined below and attributable to carfilzomib, 
lenalidomide, or dexamethasone. 
5.2.1 
NONHEMATOLOGIC DLT 
• ≥ Grade 3 nonhematological toxicity (excluding nausea, vomiting, diarrhea, alopecia, 
fatigue lasting < 14 days, increased serum creatinine or electrolyte abnormalities that are 
not clinically significant and require no treatment)  
• ≥ Grade 3 acute kidney injury (creatinine > 3 × baseline or > 4.0 mg/dL) lasting 
> 72 hours 
• ≥ Grade 3 nausea, vomiting, or diarrhea uncontrolled by maximal antiemetic/antidiarrheal 
therapy 
5.2.2 
HEMATOLOGIC DLT 
• Grade 4 neutropenia (absolute neutrophil count [ANC] < 500/mm3) lasting for > 7 days 
• Febrile neutropenia (ANC < 1000/mm3 with a fever ≥ 38.3ºC) of any duration 
• Grade 4 thrombocytopenia (platelet count < 25,000/mm3) that persists for > 14 days with 
or without platelet transfusion, despite holding treatment 
• Grade 3 or 4 thrombocytopenia (platelet count < 50,000/mm3) associated with > Grade 1 
bleeding

COHORT SAFETY REVIEW COMMITTEE  
A CSRC comprised of the lead investigator, selected additional investigators, the sponsor 
study medical monitor, and sponsor’s drug safety representative will review all available 
safety data and make recommendations regarding ongoing enrollment and opening of 
subsequent cohorts during the Dose-evaluation Components.  The CSRC will also select the 
KRd regimens to be evaluated in the Dose-expansion Components.   
5.4 
PART 1:  DOSE-EVALUATION COMPONENT  
Approximately 8 dose-evaluable subjects will be enrolled into each Dose-evaluation cohort 
(Table 2, Figure 1).  Enrollment will be gated such that the first 4 subjects in Cohort 1 will 
complete Cycle 1 and undergo a safety evaluation prior to further enrollment.   
• If ≥ 2 of the first 4 subjects of Cohort 1 experience a DLT, enrollment to that cohort will 
stop and the study will terminate 
• If ≤ 1 of the first 4 subjects experience a DLT, the cohort will recommence enrollment of 
an additional 4 subjects for up to 8 dose-evaluable subjects total 
• Cohort 2 (n = approximately 8) will open to enrollment 
When both Cohorts 1 and 2 are open for concurrent enrollment, subjects will be assigned to a 
cohort on an alternating basis.  Safety will be evaluated in both cohorts on an ongoing basis. 
• If ≥ 2 of the first 4 subjects experience DLTs or ≥ 3 subjects experience DLTs at any time 
in Cohort 2, enrollment to that cohort will be stopped, and the optional third cohort 
(Cohort 3) may be opened to enrollment of an additional 8 subjects (approximately). 
• The CSRC will review all evaluable safety data (Section 5.3).  If < 3 subjects experience 
a DLT in an opened cohort, that dose may be selected for dose expansion. 
• For NDMM subjects evaluated in Cohort 4, the CSRC will review all safety data from the 
first 2 cycles and may elect to expand NDMM enrollment 
To be DLT evaluable, subjects must have received all planned doses of carfilzomib, at least 
80% of planned doses of lenalidomide, and at least 75% of planned doses of dexamethasone 
or received at least 1 dose of carfilzomib and experienced a DLT prior to completion of study 
treatment for Cycle 1 (Cohorts 1-3) or Cycle 2 (Cohort 4).  Subjects who withdraw from 
treatment after receiving a dose of carfilzomib but before completing the first 28-day cycle 
(Cohorts 1-3) or the first two 28-day cycles (Cohort 4) for reasons unrelated to toxicity will 
be considered unevaluable for DLTs.  Subjects who are not DLT-evaluable may be replaced.

The schema for the Dose-evaluation Component of the study for RRMM subjects is 
presented in Figure 2 (Appendix E).   
A 2-step-up KRd regimen will be evaluated in NDMM subjects: carfilzomib will be given at 
20 mg/m2 on Day 1 of Cycle 1, 56 mg/m2 on Days 8 and 15 of Cycle 1, then at 70 mg/m2 on 
Days 1, 8, and 15 beginning with Cycle 2 (Cohort 4; 
Cohort 4 
Table 2).  This regimen was selected by 
the CSRC for dose-evaluation in NDMM subjects, after the occurrence of 2 SAEs in NDMM 
subjects during Cycle 1 of treatment at Cohort 2 dose level during the Arm 1 NDMM 
Dose-expansion (Figure 1). 
5.5 
PART 2:  DOSE-EXPANSION COMPONENT  
Per protocol amendment 2
Enrollment of NDMM into Dose-expansion Arm 1 will stop (Appendix E; 
: 
Figure 3).   
NDMM subjects will be enrolled into Dose-evaluation Cohort 4 (Figure 1; Table 2).  Arm 1 
subjects enrolled prior to protocol amendment 2 who are DLT evaluable at Cohort 4 dosing 
will be included in Dose-evaluation Cohort 4 (Figure 1; Table 2).   
The CSRC will evaluate all safety data for all NDMM subjects.  Following the DLT rules 
above, the CSRC may elect to open an NDMM Dose-expansion arm, and may enroll an 
additional 30 NDMM subjects (Section 5.4).    
5.6 
ACTIVE FOLLOW-UP 
Subjects who have terminated or completed study treatment (for reasons other than 
progressive disease, allogeneic stem cell transplant, death, or withdrawal of consent) will 
enter Active Follow-up for 1 year.  For subjects in Active Follow-up, tumor response and 
disease assessment measurements will be performed every 8 weeks (every 56 ± 4 days).  The 
investigators will make every reasonable effort to keep each patient in active follow-up for 
1 year, or until the subject has progressive disease (PD), begins treatment with any 
antimyeloma medication, has withdrawn consent for further participation, is lost to follow 
up, has died, or the study is closed, whichever is earliest.

5.7 
ESTIMATED STUDY DURATION AND STUDY CLOSURE 
The total study duration is expected to be a minimum of 60 months.  Approximately 
6 months will be required to enroll subjects in the RRMM Dose-evaluation Component of the 
study.  Approximately 9 months will be required to enroll subjects in the RRMM 
Dose-expansion Component of the study.  Subjects will be followed for up to 17 months in 
order to complete primary safety and efficacy evaluations with up to an additional 12 months 
of Active Follow-up.  
It will take up to approximately 12 months to enroll NDMM subjects into Dose-evaluation 
Cohort 4, review the safety data, and enroll NDMM subjects into the NDMM 
Dose-expansion Arm 3.  Subjects will be followed for up to 17 months on treatment (with an 
allowed interruption of up to 4.5 months for ASCT), and for 12 months for Active Follow up. 
Based on these assumptions, it is estimated that the final analysis will occur approximately 
60 months after the first subject is enrolled. 
The end of study will occur when the last subject leaves Active Follow-up.

A signed and dated informed consent form (ICF) will be obtained before any study-specific 
tests may be performed.  Evaluations obtained as part of routine medical care and performed 
during the screening period may be used in place of the study-specific evaluations, provided 
they meet the time windows described below.  It is recommended that study-specific tests 
unrelated to subject eligibility (including a bone marrow aspirate) be done only after 
screening tests confirm subject eligibility for the study.  Subjects will acknowledge and agree 
to the possible use of this information for the study by giving informed consent.   
SUBJECT SCREENING 
All subjects who sign consent will be assigned a unique study number.  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.   
The screening period for a particular subject commences at the point at which the subject 
signs the ICF, and must be completed within 21 days before dosing on Cycle 1 Day 1.

a Cycle 1 Day 1 carfilzomib dose level will be 20 mg/m2. 
b Dexamethasone will be administered on Day 22 of Cycles 1-8 only. 
9.2.1.1 
Carfilzomib will be administered onceweekly over 30 minutes (approximate) followed by a 
flush (see IPIM for details) on Days 1 (± 2), 8 (± 2), and 15 (± 2) of each cycle.  The dose 
can be calculated using the subject’s actual body surface area (BSA) at baseline; however, 
dosing adjustments for subsequent actual BSA determinations is allowed per institutional 
guidelines.  Subjects with a BSA > 2.2 m2 will receive a dose based upon a 2.2 m2 BSA.  
Dose adjustments must be made for weight gains/losses of ≥ 20% of baseline body weight.  
Mechanical infusion pumps are recommended but gravity-dependent infusions are permitted 
if the 30-minute infusion duration can be reliably maintained.  
Carfilzomib 
Carfilzomib will be administered at 20 mg/m2 on Cycle 1 Day 1 and given once weekly.  
Beginning on Cycle 1 Day 8 the carfilzomib dose will be according to the assigned level of 
56 mg/m2 or 70 mg/m2.   
Cohorts 1, 2, and 3

Carfilzomib will be administered once-weekly at the following dosing schedule: 20 mg/m2 
on Day 1 of Cycle 1, 56 mg/m2 on Day 8 and Day 15 of Cycle 1, and 70 mg/m2 on Day 1 of 
Cycle 2 and beyond.   
Cohort 4: 
Carfilzomib infusion must occur at a facility capable of managing hypersensitivity reactions.  
Subjects will remain at the investigational site under observation for at least 1 hour following 
each infusion of carfilzomib in Cycle 1. 
9.2.1.2 
Lenalidomide will be taken once-daily by mouth with or without food.  Lenalidomide 
capsules should be swallowed whole with water.  The capsules should not be opened, broken, 
or chewed.  Subjects will be instructed to take the lenalidomide dose at approximately the 
same time every day.  If a planned administration of lenalidomide is missed, it should be 
taken as soon as possible within the same calendar day with a return to schedule the 
following day.  If a calendar day of dosing is missed, subjects should not make up doses, but 
should resume the dosing regimen on schedule with the next course.  Missed doses must be 
reported.  
Lenalidomide 
For FCBP, nonpregnant state must be documented prior to the first dose of lenalidomide, 
every week for the first cycle, prior to the start of each subsequent cycle, and at EOT.   
Subjects must be advised to not donate blood during treatment with lenalidomide and for 
1 month following discontinuation of the drug because the blood might be given to a 
pregnant female subject whose fetus must not be exposed to lenalidomide. 
9.2.1.3 
Dexamethasone will be taken by mouth or by IV infusion once-daily on Days 1 (± 2), 8 (± 2), 
and 15 (± 2) for all cycles and on Day 22 (± 2) of Cycles 1 through 8.  Dexamethasone will 
be administered at least 30 minutes (but no more than 4 hours) prior to carfilzomib.  Subjects 
receiving dexamethasone IV on Days 1, 8, and 15 may receive dexamethasone orally on 
Day 22.

Treatment guidelines for specific hematologic toxicities are outlined in Section 9.2.2.1 and 
nonhematologic toxicities in Section 9.2.2.2.  In addition to dose reductions, administration 
of carfilzomib and/or lenalidomide may be held temporarily in the event of a 
treatment-related toxicity at the investigator’s discretion.  When administration of 
carfilzomib and/or lenalidomide is held, the reason must be documented in the case report 
form (CRF), and the medical monitor must be notified within 2 business days of the 
scheduled dose (Section 9.1). 
If either the lenalidomide or carfilzomib dose level is reduced during a given cycle, the 
reduced dose level will be continued for the next cycle.  If the reduced dose level is tolerated 
for a complete cycle, the subject may, at the investigator’s discretion, resume the dose level 
prior to the reduction at the start of the subsequent cycle.

CONCOMITANT MEDICATIONS 
A concomitant medication is defined as any prescription or over-the-counter preparation, 
including vitamins and supplements.  All concomitant medications from signing of the 
informed consent until 30 days after the subject’s last dose of study drug must be recorded on 
the electronic case report form (eCRF).  Blood or blood products are not considered 
concomitant medications and must be recorded on the appropriate eCRF. 
9.3.1 
REQUIRED CONCOMITANT MEDICATIONS 
Required prophylactic medications should be initiated at least 24 hours prior to the first 
administration of carfilzomib.  Contraception must be in place at least 4 weeks prior to the 
first administration of carfilzomib and/or lenalidomide. 
9.3.1.1 
Valacyclovir (or equivalent antiviral) is a required concomitant medication.  Valacyclovir 
500 mg orally, daily (or equivalent antiviral) should continue for the duration of treatment.  
Additional prophylaxis is at the investigator’s discretion.   
Antiviral Prophylaxis 
9.3.1.2 
Aspirin (or other anticoagulant or antiplatelet medication such as clopidogrel bisulfate, 
low-molecular-weight heparin, or warfarin), is a required concomitant medication while 
taking lenalidomide.  In subjects with a prior history of deep vein thrombosis, 
low-molecular-weight heparin or therapeutic doses of warfarin (for a target international 
normalized ratio of 2–3) are required.  Enteric-coated aspirin once-daily by mouth at the 
standard prophylactic dose should be administered for the duration of treatment with 
lenalidomide.  Subjects with known high thrombotic risk, eg, prior deep vein thrombosis, 
should receive full anticoagulation at the investigator’s discretion.  Other antiplatelet or 
anticoagulation medications may be used in cases of intolerance to aspirin upon consultation 
with the sponsor study medical monitor.

9.3.1.3 
Allopurinol (or other approved uric acid-lowering agent) in subjects at high risk for tumor 
lysis syndrome (TLS) due to high tumor burden may be prescribed at the investigator’s 
discretion.  Allopurinol dose should be prescribed according to the package insert. 
Tumor Lysis Syndrome Prophylaxis 
Subjects should be well hydrated (Section 9.2) to reduce the risk of TLS and decline in renal 
function; refer to the current Carfilzomib IB for safety guidance regarding TLS. 
9.3.1.4 
Females of childbearing potential (FCBP) must: 
Contraception 
• Avoid pregnancy for at least 4 weeks before beginning lenalidomide 
• Have 2 negative pregnancy tests prior to starting treatment, the first, a serum pregnancy 
test within 10 to 14 days and the second, a urine or serum pregnancy test within 24 hours 
before dosing on Cycle 1 Day 1 
• Pregnancy tests weekly for the first month of treatment 
• Pregnancy tests monthly during treatment after the first month or semimonthly for 
women of childbearing potential with irregular menstruation 
• Agree to abstain from heterosexual sexual intercourse or to use 2 methods of highly 
effective contraception beginning 4 weeks prior to initiating treatment with lenalidomide, 
during therapy, during dose interruptions and for 1 month following last dose of drug 
(more frequent pregnancy tests may be conducted if required per local regulations) 
An FCBP is defined as a sexually mature female who:  1) has not undergone a hysterectomy 
or bilateral oophorectomy, or 2) has not been naturally postmenopausal for at least 
24 consecutive months (ie, no menses at any time in the preceding 24 consecutive months).  
Amenorrhea following cancer therapy does not rule out childbearing potential. 
Male subjects whose partners are FCBP must use 1 highly effective method of birth control 
plus 1 additional effective method of birth control (contraception) at the SAME TIME during 
treatment and for 3 months following the last dose of drug, unless they have undergone a 
medically-confirmed successful vasectomy.  Male subjects must not donate sperm while 
taking study drugs and for 90 days after the last dose of study drugs.

9.3.2 
OPTIONAL AND ALLOWED CONCOMITANT MEDICATIONS 
Mycostatin or oral fluconazole to prevent oral thrush is optional and may be given at the 
investigator’s discretion. 
Subjects may receive antiemetics and antidiarrheal agents as necessary.  Myeloid growth 
factors may be used if neutropenia occurs but should not be given prophylactically.  Subjects 
may receive RBC transfusions, erythropoietic stimulating agents, or platelet transfusions if 
clinically indicated in accordance with institutional guidelines. 
Palliative radiation for pain management is permitted with the written approval of the study 
medical monitor. 
Bisphosphonates are permitted as indicated and in accordance with institutional guidelines. 
9.3.3 
EXCLUDED CONCOMITANT MEDICATIONS 
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 
(≥ 14 days) 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 (other than as indicated in this protocol).  Higher steroid doses given short term for 
exacerbations of nonmalignant conditions (eg, asthma flare) are permitted with the approval

All protocol-required tests and observations, along with their chronology, are outlined in the 
Schedule of Assessments (
STUDY PROCEDURES 
Appendix A).  On-study tests and observations are summarized 
below. 
10.1 
STUDY-SPECIFIC PROCEDURES 
10.1.1 
BASELINE PROCEDURES 
To be completed prior to initiation of therapy: 
• Skeletal survey (all subjects) (Section 10.1.4.3) 
• Beta-2 microglobulin (Section 10.1.4.1) 
• Plasmacytoma evaluation (if clinically indicated) (Section 10.1.4.3) 
• Bone marrow aspirate and biopsy (all subjects, Section 10.1.4.2) 
10.1.2 
VITAL SIGNS 
Vital signs will include pulse, blood pressure, respiratory rate, and temperature and will be 
assessed at Screening, prior to and after administration of carfilzomib on treatment days, and 
at EOT.  Resting blood pressure readings will be taken before administration of carfilzomib 
on Days 1, 8, and 15 of each cycle.  Pre-carfilzomib blood pressure may be assessed either 
before or after dexamethasone administration, and for a given patient should be done 
consistently before dexamethasone, or consistently after dexamethasone.  The time of pre-
carfilzomib dosing blood pressure assessment will be recorded.  The time of Day 1, 8, and 
15 dexamethasone administration will also be recorded (per report by patient if self-
administered).  During Cycles 1 through 6, 12, and 18, pre-carfilzomib blood pressure 
readings will be taken in triplicate.  In addition to the predosing blood pressure assessments, 
postdosing resting blood pressure readings will be taken in triplicate on Days 1, 8, and 15 of 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 60 of 108 
CONFIDENTIAL 
Cycles 1 through 6, 12, and 18.  Postdosing blood pressure will be assessed from 10 to 
60 minutes after completion of carfilzomib administration. 
The subject should be in a supine position in a rested and calm state for at least 5 minutes 
before blood pressure assessments are conducted.  If unable to be in a supine position, the 
subject should be in the most recumbent position possible.  The position selected for a 
subject should be the same that is uses throughout the study and documented on the vital sign 
CRF.  The arm should be supported at the level of the heart.  Every effort should be made to 
use the same instrument in measuring a subject’s blood pressure throughout the study.  When 
blood pressure measurements are taken in triplicate, readings should be taken a minute or 
more apart. 
10.1.3 
PHYSICAL EXAMINATION 
A physical examination will be performed during Screening, on Day 1 of Cycles 2 
through 18, and at the EOT.  Physical exam will include:   
• ECOG PS 
• Examination of cardiovascular and respiratory systems  
• Weight  
• BSA (at Screening and on Day 1 of Cycles 2–18 only) 
• Height (at Screening only) 
Abnormal physical examination findings during Screening will be captured as medical 
history.  Abnormal physical examination findings observed after signing of the informed 
consent will be recorded as AEs.   
10.1.4 
DISEASE ASSESSMENTS 
10.1.4.1 
Laboratory assessments of disease status will be performed at Screening (within 21 days 
before dosing on Cycle 1 Day 1); at Day 1 (± 3 days) of Cycle 2 and each cycle thereafter; at 
the EOT; and every 8 weeks (every 56 ± 4 days) during Active Follow-up. 
Laboratory Evaluations of Disease Status 

Onyx Therapeutics, Inc.

Carfilzomib 
 
Page 61 of 108 
CONFIDENTIAL 
Disease assessments at Screening (within 21 days before dosing on Cycle 1 Day 1) or 
baseline, include the following: 
• Serum protein electrophoresis (SPEP) with immunofixation 
• Urine protein electrophoresis (UPEP; 24-hour assessment, no substitute method is 
acceptable) with immunofixation 
• SFLC 
• Quantitative immunoglobulins 
• Beta-2 microglobulin 
Disease assessments at Day 1 (± 3 days) of Cycle 2 and each cycle thereafter, at the EOT, 
and during Active Follow-up include the following: 
• Serum protein electrophoresis (SPEP) with immunofixation 
• UPEP with immunofixation  
• SFLC 
• Quantitative immunoglobulins 
SPEP with immunofixation, UPEP with immunofixation, beta-2 microglobulin, SFLC, and 
quantitative immunoglobulin analyses will be performed at the local laboratory. 
10.1.4.2 
A bone marrow aspirate is required at baseline, on Cycle 8 Day 1 (± 3 days), and to confirm 
a CR or sCR.  An optional bone marrow aspirate may also be done upon progression of 
disease in subjects who consent to optional genomic biomarker studies.  Details of aspirate 
sampling and shipment are described in the central laboratory manual. 
Bone Marrow Aspirate Assessments of Disease Status 
At baseline, bone marrow aspirate will be evaluated by the local pathology lab to determine 
percent plasma cell involvement.  For subjects whose aspirate is unobtainable, a bone 
marrow core biopsy should be obtained for quantification of percent plasma cell 
involvement.  Bone marrow aspirate or biopsy samples (taken as part of standard of care) 
within 45 days prior to Cycle 1 Day 1 may be used to quantify percent plasma cell 
involvement. 
Baseline bone marrow aspirate samples are also sent to the central laboratories for 
fluorescent in situ hybridization (FISH; Section 10.2.3) and for Next Generation Sequencing

 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 62 of 108 
CONFIDENTIAL 
(NGS) to allow MRD analysis (Section 10.2.4); also referred to herein as “MRD”).  Subjects 
who consent to optional genomic biomarker evaluation will have the baseline genomic 
biomarker analyses performed on aspirate samples remaining after central FISH testing of 
baseline aspirate.  
Bone marrow aspirate will be collected for central MRD analysis on Cycle 8 Day 1 for all 
subjects regardless of response status (± 2 days; see Section 10.2.4). 
Subjects with laboratory evidence of CR require confirmatory bone marrow aspirate 
evaluation, by the central study laboratory, for MRD (Section 10.2.4), in addition to local 
bone marrow assessment for evaluation of CR per IMWG-URC (Appendix C).  
Consenting subjects with PD may have a bone marrow aspirate done for optional genomic 
biomarker studies (Section 10.2.5). 
In instances where sample availability is limited, samples for disease assessments take 
priority over those for correlative testing as specified in the laboratory manual. 
10.1.4.3 
All subjects will have a baseline skeletal survey.  Repeat skeletal survey is recommended as 
clinically indicated. 
Imaging Assessments of Disease Status 
Subjects with physical exam findings suggestive of plasmacytoma should undergo baseline 
imaging with computed tomography [CT] scan, magnetic resonance imaging [MRI], or 
positron emission tomography/CT [PET/CT]. 
Repeat plasmacytoma imaging is required only to confirm a response of PR or better, to 
confirm PD, or if clinically indicated.  The same imaging technique should be employed for 
each measurement. 
For study purposes, a plasmacytoma is considered measurable if the longest diameter is at 
least 1 cm and the product of the greatest orthogonal cross-diameters is at least 1 cm2.

10.1.5 
MYELOMA RESPONSE ASSESSMENT 
Response will be determined by the investigator based on the disease assessments described 
above and the IMWG-URC (see definitions in Appendix C).  Myeloma response laboratory 
studies will be drawn at the beginning of each cycle before treatment.  The following 
confirmatory assessments are required for all response categories (stringent complete 
response [sCR], CR, VGPR, and PR) and progressive disease: 
• All laboratory-based progressive disease and all responses require 2 consecutive 
assessments made at any time before initiation of any new (ie, off protocol) therapy.  
Confirmatory lab samples should be separated by at least 1 calendar day 
• Progressive disease by nonlaboratory-based assessment (ie, plasmacytoma or skeletal 
lesion) does not require confirmatory report 
• All response categories also require no evidence of progression including new bone 
lesions, if radiographic studies are performed 
• Confirmation of CR or sCR requires local pathology review of a bone marrow biopsy or 
aspirate (a repeat confirmatory bone marrow sample is not required) 
• Extramedullary plasmacytoma evaluation is required to confirm PR, CR, or sCR (if 
present at baseline; Rajkumar, 2011) 
10.1.6 
CLINICAL LABORATORY TESTS  
Clinical laboratory assessments will include the following: 
• Hematology:  hemoglobin, hematocrit, white blood cell (WBC) with complete 
differential (total neutrophils, lymphocytes, monocytes, eosinophils, basophils), RBCs, 
platelet count   
• Full serum chemistry panel:  sodium, potassium, chloride, bicarbonate, blood urea 
nitrogen (BUN), creatinine, glucose, calcium, magnesium, phosphate, AST, ALT, total 
protein, albumin, alkaline phosphatase, total bilirubin, uric acid, and lactate 
dehydrogenase (LDH)  
• Abbreviated chemistry panel:  sodium, potassium, chloride, bicarbonate, BUN, 
creatinine, glucose 
• Coagulation tests:  prothrombin time, activated partial thromboplastin time, and 
international normalized ratio 
Hematology and serum chemistry (full or abbreviated) will be performed at Screening, on 
Days 1, 8, and 15 of each cycle, and at EOT.  On Days 8 and 15 of each cycle, from Cycle 2 
onwards, an abbreviated serum chemistry panel may be performed.  C oagulation will be 
performed at baseline and at EOT.  For screening laboratory samples, historical panel may be 
used if within 21 days prior to dosing on Cycle 1 Day 1.  Thereafter, hematology samples

may be obtained anytime within the 24 hours prior to the carfilzomib administration, and full 
or abbreviated chemistry panels may be performed up t o 72 hours prior to carfilzomib 
administration.  
10.1.7 
ELECTROCARDIOGRAM 
Twelve-lead electrocardiograms (ECGs) including corrected QT interval (QTc; representing 
the corrected duration of ventricular electrical activity) will be performed locally.  These will 
be required in all subjects at Screening only.  Additional ECG assessment is only required if 
clinically indicated 
10.1.8 
ECHOCARDIOGRAM 
A 2-D transthoracic ECHO to assess LVEF will be performed in all subjects at Screening and 
at EOT.  During the Dose-evaluation Component, an ECHO is also required at Cycle 2 
Day 15, ± 7 days.  Additional ECHO assessment is only required for subjects who develop 
clinically significant congestive heart failure.   
If transthoracic ECHO is not available, multigated acquisition (MUGA) will be acceptable 
for LVEF evaluation. 
10.1.9 
SUBJECT CONVENIENCE AND SATISFACTION 
Subject convenience and satisfaction will be assessed in all subjects by questionnaire at 
Cycle 3 Day 1 and Cycle 18 Day 1 (see Appendix D).  The questionnaire should be 
administered prior to treatment with carfilzomib.  
10.2 
CORRELATIVE STUDIES 
It is recommended that samples for correlative studies be collected only after screening 
laboratories confirm study eligibility for the subject. 
10.2.1 
PHARMACOKINETIC MEASUREMENTS 
For both the Dose-evaluation and the Dose-expansion Components, blood samples will be 
collected from all subjects on Day 8 of Cycle 1 for determination of plasma concentrations 
of carfilzomib. 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 65 of 108 
CONFIDENTIAL 
Blood samples will be collected at the following time points: 
• Predose (within 5 minutes before start of carfilzomib infusion) 
• 15 minutes (± 5 minutes) after the start of carfilzomib infusion 
• Immediately prior to (within 2 minutes before) the end of carfilzomib infusion 
• 15 minutes (± 5 minutes) after the end of carfilzomib infusion  
• 60 minutes (± 5 minutes) after the end of carfilzomib infusion 
The actual time of PK sample collection will be recorded.  Samples should be collected 
within a ± 5 minute time window around the nominal time points (except for the time point 
immediately prior to the end of carfilzomib infusion in which the PK collection needs to 
occur prior to end of infusion).  Collecting PK samples at times other than nominal time 
points will not constitute a protocol deviation.  These samples will be assessed at a central 
laboratory.  Directions for collection, processing, and shipping of PK blood samples are 
provided in the central laboratory manual.   
10.2.2 
PHARMACODYNAMIC MEASUREMENTS 
For pharmacodynamic measurements, whole blood will be collected from the subjects on the 
following schedule: 
For the Dose-evaluation component Cohorts 1 and 2, and the first 8 subjects enrolled into 
Dose-expansion Arm 3, whole blood will be collected.  On Days 1 and 8 of Cycle 1, whole 
blood will be collected pre-carfilzomib dose and post-carfilzomib dose.  On Days 9 and 
11 of Cycle 1, when carfilzomib is not administered, one PDn sample will be collected at 
approximately the same time as when the pre-infusion sample was taken on Day 8. 
Directions for collection, processing, and shipping of PDn samples are provided in the 
central laboratory manual.   
10.2.3 
FLUORESCENT IN SITU HYBRIDIZATION (FISH) TESTING 
Bone marrow aspirate from all subjects will be evaluated centrally, at baseline, by FISH.  
Directions for collection, processing, and shipping of FISH samples are provided in the 
central laboratory manual.

MINIMAL RESIDUAL DISEASE 
Analysis of MRD status will be performed by the central laboratory on all subjects by 
2 methods:  
Flow cytometry (FC) of cell surface markers and  
NGS of DNA and/or RNA from the Ig locus.   
The MRD analysis by FC will be performed on bone marrow aspirate samples collected at 
2 time points:  Cycle 8 Day 1 and upon achieving a CR or sCR.  The MRD analysis by NGS 
will be performed on blood and bone marrow aspirate samples collected at 3 time points:  
baseline, Cycle 8 Day 1, and upon achieving a CR or sCR. 
Directions for collection, processing, and shipping of MRD samples are provided in the 
central laboratory manual. 
10.2.5 
OPTIONAL GENOMIC BIOMARKERS 
Analysis of genetics, gene expression, and cell surface biomarkers that may be predictive of 
response and resistance to treatment with proteasome inhibitors will be performed.  
Exploratory studies will be conducted on all subjects who consent to optional genomic 
biomarker analysis.  These analyses will be performed on bone marrow aspirate at baseline 
(the remaining portion of the bone marrow aspirate sample left after the amount required for 
FISH analysis has been collected at baseline), as well as a sample of blood and saliva also 
collected at baseline.  At disease progression, an additional bone marrow sample for 
biomarker analysis may be collected from all subjects who consent. 
Whole genome sequencing (WGS), whole exome sequencing (WES), whole transcriptome 
sequencing (RNA-Seq), and/or other methods of nucleic acid and protein quantification will 
be conducted on isolated tumor (CD138+) cells from bone marrow samples taken at baseline 
and disease progression.  In addition, WGS or WES will be performed on a normal tissue 
sample (eg, CD3+ T cells isolated from peripheral blood or saliva) to distinguish germ line 
mutations from somatic mutations in tumor cell samples.

11.1 
WITHDRAWAL OF SUBJECTS FROM TREATMENT 
STUDY DISCONTINUATION 
Subjects may withdraw from study treatment at any time.  Reasons for discontinuation 
include: 
• Adverse event 
• Allogeneic stem cell transplant 
• Pregnancy 
• Death 
• Lost to follow-up 
• Noncompliance 
• Withdrawal by subject 
• Study terminated by the sponsor 
• Physician decision 
• Progression of disease 
• Other 
The primary reason for treatment discontinuation will be documented in the eCRF.  
Investigators will be instructed to interview subjects to obtain the most accurate reason for 
study treatment discontinuation while respecting the privacy of the subject.  
If the reason for treatment discontinuation is the occurrence of an AE, the subject will be 
followed by the investigator until such event(s) resolve, stabilize, and, according to the 
investigator’s judgment, there is no need of further follow-up.  
Treatment discontinuation due to progression should be recorded as “Disease Progression.”  
If the Disease Progression meets any of the serious criteria, as outlined in Section 12.2.1.4, 
then it should also be recorded as a serious adverse event (SAE) in the AE eCRF. 
Sponsor or designee must be notified within 24 hours if a subject is withdrawn from 
treatment.

All subjects who withdraw or are withdrawn from study treatment will be encouraged to 
complete all relevant safety assessments and continue in the Active Follow-up period.  
11.2 
WITHDRAWAL OF SUBJECTS FROM STUDY 
Reasons for complete withdrawal from the study (treatment and all follow-up) before 
documentation of subject death include: 
• Withdrawal of consent by subject for all study procedures 
• Lost to follow-up 
• Sponsor decision 
The reason for complete withdrawal from study will be documented in the eCRF. 
11.3 
STUDY TERMINATION 
The sponsor has the right to terminate this study or a study site from participating in a study 
at any time.  Reasons for study termination may include: 
• The incidence or severity of AEs in this or other carfilzomib studies indicates a potential 
health hazard to subjects 
• Subject enrollment is unsatisfactory 
• Data recording is inaccurate or incomplete 
• Investigator does not adhere to the protocol or applicable regulatory requirements in 
conducting the study 
12 
12.1 
DEFINITION OF SAFETY EVENTS 
SAFETY DATA COLLECTION, RECORDING, AND REPORTING 
12.1.1 
ADVERSE EVENTS 
An AE 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 AEs observed by the investigator or reported by the subject 
are recorded in the subject’s medical record.   
The definition of AEs 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 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 69 of 108 
CONFIDENTIAL 
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 AE.   
For situations when an AE or SAE 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 AE.   
The investigator’s clinical judgment is used to determine whether a subject is to be removed 
from treatment due to an AE.  In the event a subject, or subject’s legally acceptable 
representative requests to withdraw from protocol-required therapies or the study due to an 
AE, refer to Section 11 for additional instructions on the procedures recommended for safe 
withdrawal from protocol-required therapies or the study.   

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 70 of 108 
CONFIDENTIAL 
12.1.2 
SERIOUS ADVERSE EVENTS 
A serious adverse event is defined as an AE 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 
• results in persistent or significant disability/incapacity 
• congenital anomaly/birth defect 
• other medically important serious event 
An AE 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 SAE 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.   
12.2 
SAFETY EVENT REPORTING PROCEDURES  
12.2.1 
ADVERSE EVENTS 
12.2.1.1 
The investigator is responsible for ensuring that all AEs observed by the investigator or 
reported by the subject that occur after signing the informed consent form through 30 days 
after receiving the last dose of study drugs are reported using the Event CRF.   
Reporting Procedures for Adverse Events That do not Meet Serious 
Criteria 
If initiation of new anticancer therapy occurs within 30 days following the last dose of study 
drugs, the date of new anticancer therapy will be recorded on the appropriate eCRF.  In 
addition, the investigator should report any AEs that may occur after this time period which 
are assessed to have a reasonable possibility of being associated with study drug. 
For subjects who complete the EOT visit less than 30 days following the last dose of study 
drug, a follow-up of ongoing AEs should be attempted by telephone and documented in the 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 71 of 108 
CONFIDENTIAL 
subject’s source file.  AEs continuing at 30 days after the last dose of study treatment should 
have a comment in the source file by the investigator that the event has stabilized or is not 
expected to improve. 
The investigator must assign the following AE attributes: 
• AE 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 carfilzomib and/or other protocol-required therapies 
• Action taken. 
The adverse event grading scale used will be the Common Terminology Criteria for Adverse 
Events (CTCAE).  The grading scale used in this study is described in Appendix F.   
The investigator must assess whether the AE is possibly related to carfilzomib and/or other 
protocol-required therapies.  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 
carfilzomib and/or other protocol-required therapies?   
In the event of a possible drug-related AE, the investigator should to the best of his/her 
ability assess its relationship to each of the study drugs:  carfilzomib, lenalidomide, and/or 
dexamethasone. 
The investigator is responsible for reviewing laboratory test results and determining whether 
an abnormal value in an individual study subject represents a clinically significant change 
from the subject’s baseline values.  In general, abnormal laboratory findings without clinical 
significance (based on the investigator's judgment) are not to be recorded as AEs.  However, 
laboratory value changes that require treatment or adjustment in current therapy are 
considered AEs.  Where applicable, clinical sequelae (not the laboratory abnormality) are to 
be recorded as the AE. 
The Investigator is expected to follow reported AEs until stabilization or reversibility.  

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 72 of 108 
CONFIDENTIAL 
12.2.1.2 
The investigator is responsible for ensuring that all SAEs observed by the investigator or 
reported by the subject that occur after through 30 days after the last day of the study drug 
are recorded in the subject’s medical record and are submitted to Amgen.  All SAEs must be 
submitted to Amgen within 24 hours following the investigator’s knowledge of the event via 
the Event CRF.   
Reporting Procedures for Serious Adverse Events 
If the electronic data capture (EDC) system is unavailable to the site staff to report the SAE, 
the information is to be reported to Amgen via an electronic SAE Contingency Report Form 
within 24 hours of the investigator’s knowledge of the event.  See Appendix G for a sample 
of the SAE Worksheet /electronic SAE Contingency Report Form.  For EDC studies where 
the first notification of a SAE is reported to Amgen via the electronic SAE Contingency 
Report Form, the data must be entered into the EDC system when the system is again 
available. 
The investigator must assess whether the SAE is possibly related to carfilzomib and/or other 
protocol-required therapies.  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 carfilzomib 
and/or other protocol-required therapies?  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 SAEs until stabilization or reversibility.  
New information relating to a previously reported SAE must be submitted to Amgen.  All 
new information for SAEs 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. Information provided about the SAE must be consistent with that 
recorded on the Event CRF. 
If a subject is permanently withdrawn from protocol-required therapies because of a SAE, 
this information must be submitted to Amgen. 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 73 of 108 
CONFIDENTIAL 
Amgen will report SAEs and/or suspected unexpected serious adverse reactions as required 
to regulatory authorities, investigators/institutions, and Institutional Review Board 
(IRB)/Independent Ethics Committee (IEC) in compliance with all reporting requirements 
according to local regulations and good clinical practice.  
The investigator is to notify the appropriate IRB/IEC of SAEs occurring at the site and other 
AE reports received from Amgen, in accordance with local regulatory requirements and 
procedures. 
12.2.1.3 
There is no requirement to monitor study subjects for SAEs following the protocol-required 
reporting period or after end of study.  However, these SAEs can be reported to Amgen.  In 
some countries (eg, European Union [EU] member states), investigators are required to 
report SAEs that they become aware of after end of study.  If SAEs are reported, the 
investigator is to report them to Amgen within 24 hours following the investigator’s 
knowledge of the event. 
Reporting Serious Adverse Events After the Protocol-required Reporting 
Period 
Serious adverse events reported outside of the protocol-required reporting period will be 
captured within the safety database as clinical trial cases for the purposes of expedited 
reporting.  
12.2.1.4 
Disease progression will be documented in an eCRF intended to capture PD information and 
will be analyzed as a study endpoint.  Signs and symptoms related to disease progression 
(eg, pathologic fracture in a subject with progressive multiple myeloma) should be reported 
in the appropriate CRF as an AE or as an SAE (if the event in question meets the criteria for 
seriousness).  Verbatim terms such as “disease progression,” “progressive disease,” etc. 
should not be reported as AEs or SAEs unless the investigator considers the progression to be 
atypical, accelerated, or caused by the study drug.  Similarly deaths occurring as a result of 
disease progression should be reported on the eCRF intended to capture death information 
and should not be reported as SAEs. 
Serious Adverse Events That are not to be Reported by the Sponsors to 
Regulatory Agencies in an Expedited Manner

12.3 
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 in female subjects 30 days after the last study drug 
administration, and in a male subject’s spouse or partner while enrolled in this clinical study 
through 90 days following the last study drug administration. 
The pregnancy should be reported to Amgen Global Patient Safety within 24 hours of the 
investigator’s knowledge of the event of a pregnancy.  Report a pregnancy on the Pregnancy 
Notification Worksheet (Appendix H) 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, the investigator should attempt to 
obtain information regarding the birth outcome and health of the infant.  Newborns should be 
followed for a minimum of 12 weeks.   
If the outcome of the pregnancy meets a criterion for immediate classification as a SAE 
(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 SAE.  
If a female breastfeeds while taking protocol-required therapies report the lactation case to 
Amgen as specified below.  
Any lactation case should be reported to Amgen Global Patient Safety within 24 hours of the 
investigator’s knowledge of event.  Report a lactation case on the Lactation Notification 
Worksheet (Appendix H).   
Amgen Global Patient Safety will follow-up with the investigator regarding additional 
information that may be requested.

The final analysis will be based upon subject data collected through discontinuation of the 
final subject from study participation or until study discontinuation by the sponsor, 
whichever occurs first.  All efficacy and safety analyses will be based upon the Safety 
Population, defined as subjects receiving at least 1 dose of study drug.  All summaries will be 
presented by the assigned dose cohort level, by RRMM and NDMM population, as well as 
for the overall Safety Population.  In addition, response data (ORR, complete response rate 
[CRR], PFS, DOR) may also be analyzed based on the Response-evaluable Population, 
defined as subjects who are included in the Safety Population, have a baseline disease 
assessment and at least 1 postbaseline disease assessment, or dropped out due to AE prior to 
the first postbaseline disease assessment.

all subjects by dose cohort level.  Point estimates for ORR and CRR along with their exact 
2-sided 95% confidence intervals will be calculated.  Summary statistics for DOR and PFS 
will be calculated using the Kaplan-Meier method.  The follow-up time for PFS will be 
summarized by reverse Kaplan-Meier method (Schemper 1996). 
13.5.2 
SAFETY ANALYSIS 
Safety will be assessed through summaries of AEs, changes from baseline in laboratory test 
results, including immunoglobulin levels, and vital signs, and the extent and duration of 
exposure to study drugs.  All treatment-emergent AEs will be summarized by MedDRA 
preferred term, NCI-CTCAE (version 4.03) toxicity grade, and investigator assessment of 
causality.  In addition, all SAEs and DLTs, including deaths, will be listed separately.  Extent 
of exposure to the study treatment will be summarized using descriptive statistics.  
Laboratory parameters will be summarized using descriptive statistics and by postdose shifts 
relative to baseline.  Vital signs will also be summarized descriptively for each scheduled 
protocol time point.    
13.5.3 
PHARMACOKINETIC ANALYSES  
Actual collection times will be recorded and used in the analysis.  Individual and mean 
plasma concentration versus time data will be tabulated and plotted by dose level.  The PK 
parameter estimates for carfilzomib will be summarized, including total plasma exposure 
(expressed as area under the curve [AUC]), maximum plasma concentration (Cmax), time to 
maximum plasma concentration (Tmax), total plasma clearance, and plasma terminal half-life 
(as appropriate for data collected).  Estimates for these parameters will be tabulated and 
summarized (ie, mean, standard deviation). 
Unless otherwise specified, the PK parameter will be estimated based on noncompartmental 
methods.  These estimates will be summarized descriptively by dose cohort and population.  
Exploratory analyses may be performed to evaluate the relationship between the estimated 
PK parameters and selected safety, biomarker, or clinical effect endpoints. 
In addition to noncompartmental PK analysis, the population modeling program may be used 
to fit a nonlinear mixed effects model to estimate PK parameters including clearance and

volume of distribution, the inter- and intra-subject variability and the population variability in 
the parameter estimates.  The PK concentrations obtained from subjects in the 
Dose-expansion portion, along with results from the Dose-evaluation Component of the 
study and other carfilzomib studies will be used in the development of a structural model.  
The best model will be evaluated by goodness of fit statistics and reduction in the objective 
function and posterior predictive checks.  Subject characteristics such as age, gender, body 
weight, BSA, and race will be included in the model to identify potential covariates affecting 
PK of carfilzomib.  Results from the population PK modeling will be reported separately. 
13.5.4 
EXPLORATORY ANALYSES  
Exploratory analyses of MRD[-] rate, PDn, and genomic biomarkers may be conducted.  
Point estimates for MRD[-] rate along with exact 2-sided 95% confidence intervals will be 
calculated.  MRD measurements will be correlated with ORR, CRR, PFS, and other clinical 
variables to explore the relationship of MRD to disease response and progression. 
PDn will be determined from whole blood. 
For genomic biomarker analyses, WGS, WES, RNA-Seq, and/or other forms of nucleic acid 
and protein data will be analyzed to characterize whether drug response is related to 
alterations in genes regulated by or involved in activation of nuclear factor kappa light chain 
enhancer of activated B cells (NF-Kappa B) transcription factors as well as in genes involved 
in immunoglobulin production and protein homeostasis.  Immunoglobulin levels in tumor 
cells will be quantified by enzyme-linked immunosorbent assay (ELISA) and/or other protein 
quantification methods.  The genomic data as a whole will also be used to derive new 
hypotheses about mechanisms of drug response, resistance, and safety. 
Results from the subject convenience and satisfaction questionnaire will be summarized 
descriptively. 
13.6 
HANDLING OF MISSING DATA 
Missing data for partial dates for AEs or concomitant medication may be imputed according 
to prespecified, conservative imputation rules.  Details of missing data handling and 
imputation rules will be specified in the statistical analysis plan.

CONFIDENTIAL 
Subjects with no postbaseline response assessments will be classified as nonresponders in the 
estimation of ORR and CRR.  
Progression and survival data will be collected for all subjects on study.  For subjects who 
discontinue without having experienced progression or death, progression will be censored at 
the time of the last on-study disease assessment demonstrating lack of progression.  Details 
of censoring rules will be specified in the statistical analysis plan.  
13.7 
DETERMINATION OF SAMPLE SIZE 
Sample sizes are determined to provide preliminary information on safety, clinical activity, 
PDn, and PK.  
For the Dose-evaluation Component of the study, it is anticipated that approximately 
8 subjects will be enrolled in each dose cohort with 16 subjects total, should both cohorts be 
fully enrolled.  Assuming beta (0.5, 0.5) prior distribution for the DLT rate, 95% credible 
intervals for the DLT rate and the posterior probability of DLT rate being larger than 0.33 for 
each toxicity scenario are provided in Table 12.  For example, when 3 out of 8 subjects have 
DLTs, the posterior probability of the DLT rate being > 0.33 is 0.62.

With combined number of subjects in both dose finding and expansion components, 
38 RRMM subjects and 38 NDMM subjects will allow an approximately 86% probability to 
detect an occurrence of an AE with 5% incidence rate.

INTERIM ANALYSIS  
No formal interim analyses with the purpose of stopping the study early for efficacy or 
futility will be conducted for this study.  However, the following nonbinding boundaries are 
calculated to provide more information about the distribution of ORR for subjects with 
relapsed disease.  
For subjects with relapsed disease, under the null hypothesis of ORR ≤ 55%, the alternative 
hypothesis of ORR ≥ 75%, and the beta (0.65, 0.35) prior distribution for the true ORR, the 
boundaries for number of subjects with overall responses based on Bayesian predictive 
probability (Lee 2008) are listed below in Table 13.

COMPLIANCE STATEMENT 
ETHICAL AND ADMINISTRATIVE CONSIDERATIONS 
This study will be conducted in accordance with the protocol and with International 
Conference on Harmonisation (ICH) Good Clinical Practice (GCP) guidelines, as well as all 
applicable country and regional legal and regulatory requirements.  The investigator is 
responsible for ensuring that this protocol, the site’s ICF, and any other information that will 
be presented to potential subjects are reviewed and approved by the appropriate Institutional 
Review Board (IRB) or Independent Ethics Committee (IEC) prior to the enrollment of any 
study subjects. 
14.2 
INSTITUTIONAL REVIEW BOARD OR INDEPENDENT ETHICS 
COMMITTEE 
The investigator will submit this protocol, the informed consent, investigator’s brochure (IB), 
and any other relevant supporting information to the appropriate IRB or IEC and the local 
regulatory agency (where required) for review and approval prior to study initiation. 
Amendments to the protocol must also be approved by the IRB/IEC and the local regulatory 
agency, as appropriate, prior to the implementation of changes in this study.  No protocol 
deviations are allowed.  However, the investigator may implement a deviation from, or a 
change of, the protocol to eliminate an immediate hazard(s) to the study subjects without 
prior IRB/IEC/sponsor approval/favorable opinion.  As soon as possible, the implemented 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 82 of 108 
CONFIDENTIAL 
deviation or change, the reasons for it, and, if appropriate, the proposed protocol amendment, 
should be submitted to the IRB/IEC/sponsor.  Any deviations from the protocol must be fully 
explained and documented by the investigator. 
14.3 
INFORMED CONSENT AND HUMAN SUBJECT PROTECTION 
No investigator may involve a human being as a subject in research unless the investigator 
has obtained the legally effective informed consent of the subject or the subject’s legally 
authorized representative.  An investigator shall seek such consent only under circumstances 
that provide the prospective subject or the subject’s legally authorized representative 
sufficient opportunity to consider whether or not to participate, and that minimize the 
possibility of coercion or undue influence.  The information that is given to the subject or the 
representative shall be in a language understandable to the subject or representative. 
The sponsor or its designated representative will provide the investigator with a sample 
consent form.  Local and/or institutional requirements may require disclosure of additional 
information in the ICF.  Any changes to the consent form must be submitted to the sponsor or 
its designated representative for acceptance, prior to submission to the IRB/IEC.  
The IRB/IEC will review the consent form for approval.  A copy of the approved form must 
be submitted to the sponsor or its designated representative for its acceptance prior to 
initiation of the study.  Before implementing any study procedure on a particular subject, 
informed consent shall be documented in such subject’s case histories and by the use of a 
written consent form approved by the sponsor and the IRB/IEC and signed and dated by the 
subject or the subject’s legally authorized representative at the time of consent.  A copy of 
the signed informed consent will be given to the subject or subject’s legally authorized 
representative.  The original signed consent must be maintained by the investigator and 
available for inspection by the sponsor, its designated representative, or regulatory authority 
at any time. 
14.4 
DIRECT ACCESS TO SOURCE DATA, SOURCE DOCUMENTS, AND 
STUDY RECORDS 
The study will be carried out in keeping with applicable local laws and regulations.  
This may include an inspection by sponsor representatives/designees, and/or regulatory 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 83 of 108 
CONFIDENTIAL 
authority representatives at any time.  The investigator/institution must agree to the 
inspection of study-related records by the regulatory authority/sponsor 
representatives/designees, and must allow direct access to source documents to the regulatory 
authority/sponsor representatives/ designees/IRB/IEC.  The investigator must allocate time 
(investigator and study staff) to discuss findings and relevant issues with the regulatory 
authority/sponsor representatives. 
14.5 
DATA COLLECTION AND HANDLING 
As part of the responsibilities assumed by participating in the study, the investigator agrees to 
maintain adequate case histories for the subjects treated as part of the research under this 
protocol.  The investigator agrees to maintain accurate eCRFs and source documentation as 
part of the case histories.  These source documents may include subject diaries, laboratory 
reports, and other documents.  The sponsor will supply the eCRF, which will be completed in 
English. 
Data collection will involve the use of the EDC system, to which only authorized personnel 
will have access. 
The investigator or designee must enter all results collected during the clinical study into 
eCRFs.  Guidelines for completion of eCRFs will be reviewed with study site personnel at 
the site initiation visits.  Investigators are responsible for approval of the entered/corrected 
data.  Detailed instructions may be found in the other study-specific documents. 
All entries made on the eCRF, must be verifiable against source documents.  In addition to 
periodic monitoring occurring within the system by study monitors, programmatic edit 
checks and data listings will be used to review the data for completeness, logic, and 
adherence to study protocol.  As a result of this monitoring and these checks, queries may be 
electronically issued to the clinical study sites and electronically resolved by those sites. 
All data collected in the context of this study will be stored and evaluated per regulatory 
requirements and applicable guidance for electronic records.  Also, data will be stored and 
evaluated in such a way as to assure subject confidentiality in accordance with the legal and 
regulatory requirements applying to protected health information.  Study records (eg, copies 

Onyx Therapeutics, Inc. 
 Clinical Study Protocol No. CFZ013 
Carfilzomib 
 
Page 84 of 108 
CONFIDENTIAL 
of eCRFs, regulatory documents) will be retained at the study site, along with adequate 
source documentation.  The study file and all source data should be retained for the time 
period required by applicable regulatory requirements and will not be destroyed until written 
notification is given by the sponsor or designee for destruction. 
14.6 
CONFIDENTIALITY 
All records identifying the subject will be kept confidential and, in accordance with the 
applicable laws and/or regulations, will not be made publicly available. 
Subject names will not be supplied to the sponsor.  Only the subject number will be recorded 
on the case report form (CRF).  If the subject name appears on any other document 
(eg, pathologist report) or study materials (eg, biopsy tissue slides), then that information 
must be redacted before a copy of the document is supplied to the sponsor.  Study data stored 
on a computer will be stored in accordance with local data protection laws and regulations.  
Subjects will be informed in writing that representatives of the sponsor, IRB/IEC, or 
regulatory authorities may inspect their medical records to verify the information collected, 
and that all personal information made available for inspection will be handled in strictest 
confidence and in accordance with local data protection laws and regulations. 
If the results of the study are published, the subject’s identity will remain confidential. 
The investigator will maintain a list to enable subjects’ records to be identified in accordance 
with applicable laws and regulations and according to the terms and agreed upon in such 
subjects’ signed consent forms. 
14.7 
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.

CONFIDENTIAL 
Authorship of any publications resulting from this study will be determined on the basis of 
the International Committee of Medical Journal Editors 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.

Summary of International Myeloma Working Group Uniform Response Criteria 
(IMWG-URC) (cont’d) 
PD 
• Increase of 25% from lowest response value in any of the following: 
o Serum M-component (absolute increase must be ≥ 0.5 g/dL) 
o Urine M-component (absolute increase must be ≥ 200 mg per 
24 hours) 
and/or 
o Only in patients without measurable serum and urine M-protein 
levels:  the difference between involved and uninvolved FLC 
levels (absolute increase must be >10 mg/dL) 
and/or 
• Definite development of new bone lesions or soft tissue 
plasmacytomas or definite increase in size of existing bone lesions or 
soft tissue plasmacytomas  
• Development of hypercalcemia (corrected serum calcium 
> 11.5 mg/dL or 2.875 mmol/L) attributed solely to the plasma cell 
proliferative disorder 
CR = complete response; sCR = stringent complete response; FLC = serum free light chain; PD = progressive 
disease; PR = partial response; SFLC = serum free light chain; VGPR = very good partial response. 
 
All response categories (CR, sCR, VGPR, PR, PD) require 2 consecutive assessments made 
at any time before the institution 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. SD requires a duration of ≥ 6 weeks. 
For sCR:  presence/absence of clonal cells is based upon the kappa lambda (κ/λ) ratio.  An 
abnormal ratio reflecting presence of an abnormal clone is κ/λ > 4:1 or < 1:2. An abnormal 
kappa lambda ratio by immunohistochemistry and/or immunofluorescence requires a 
minimum of 100 plasma cells for analysis.  For CR:  A normal SFLC kappa lambda ratio is 
0.26 to 1.65. 
“Measurable” disease is defined by at least one of SPEP ≥ 0.5 g/dL, UPEP ≥ 200 mg per 
24 hours, or in subjects without detectable serum or urine M-protein, SFLC > 100 mg/L 
(involved light chain) and an abnormal kappa lambda ratio.

Determination of PD while on study requires 2 consecutive assessments made at any time 
before classification of PD and/or the institution of new therapy.  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 as measured 
serially by the sum of the products of the greatest orthogonal cross-diameters of the 
measurable lesions. A plasmacytoma is considered measurable if the longest diameter is at 
least 1 cm and the product of the greatest orthogonal 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.

APPENDIX I  
SUMMARY OF CHANGES IN STUDY CFZ013 
AMENDMENT 3 
This Summary of Changes outlines noteworthy changes from protocol amendment 2.0 to 
protocol amendment 3.0, and includes rationales for the changes.  Administrative updates, 
typographical and formatting changes were made throughout the protocol.  The main 
purposes for revising the CFZ013 (20140241) protocol are listed below. 
Protocol amendment 3 specifies the dosing selected for newly diagnosed multiple 
myeloma (NDMM) Dose-expansion Arm 3.  The carfilzomib, lenalidomide, and 
dexamethasone (KRd) dosing for Arm 3 is as follows: carfilzomib 20 mg/m2 on Day 1 of 
Cycle 1, then 56 mg/m2 on Days 8 and 15 of Cycle 1, and Days 1, 8, and 15 of Cycles 
2-18.  Lenalidomide will be given at 25 mg on Days 1-21, and dexamethasone at 40 mg 
on Days 1, 8, 15, 22 of Cycles 1-8, and on Days 1, 8, and 15 of Cycles 9-18 (see Cohort 1 
dosing in Table 2). 
The pharmacokinetics (PK) and pharmacodynamics (PDn) sample collection schedule 
was modified to reflect the dosing selected.  Cycle 2 sampling that was introduced in 
protocol amendment 2, in anticipation of a 2-step-up dosing regimen, has been removed 
as it is not required for the dosing selected for Dose-expansion Arm 3. 
Two revisions were made in response to the carfilzomib US Prescribing Information 
(USPI) labelling change approved by FDA in November 2016, which required a 25% 
dose reduction in patients with mild or moderate hepatic impairment: 
• Table 9 (Treatment Guidelines for Nonhematologic Toxicity) has been modified 
to align with requested changes.  Specifically, NCI Organ Dysfunction Working 
Group definition of mild, moderate and severe hepatic impairment were used 
(Shibata et al, 2013): 
o mild: total bilirubin (>33% direct) > the upper limit of normal (ULN) 
and ≤ 1.5x ULN OR total bilirubin (>33% direct) ≤ ULN and alanine 
aminotransferase (ALT) or aspartate aminotransferase (AST) > ULN;  
o moderate: total bilirubin  .5x ULN and ≤ 3x ULN, any ALT or AST;  
o severe: total bilirubin > 3x ULN, any ALT or AST.   
Subjects with treatment-emergent mild or moderate hepatic impairment, per 
this definition, are to have a 25% carfilzomib dose reduction.  In cases of severe

Clinical Study Protocol No. CFZ013 
Carfilzomib 
Page 108 of 108 
CONFIDENTIAL 
hepatic impairment, carfilzomib is to be held.  In moderate or severe hepatic 
impairment, lenalidomide is to be held. 
• Inclusion criteria have been modified in Section 6.1.  Previous protocol 
amendments allowed enrollment of subjects with baseline mild hepatic 
insufficiency.  With protocol amendment 3 (under which only the NDMM dose-
expansion Arm 3 subjects will be enrolled), subjects will be required to have 
normal hepatic function.  The intent of this modification is to maximize the 
ability to give full, protocol-specified 20/56 mg/m2 carfilzomib dosing to the 
enrolled NDMM subjects. 
Other minor changes: 
• To maintain internal consistency of the document, Dose-expansion groups are 
uniformly referred to “Arms” with the term “Cohort” reserved for Dose-
evaluation groups.  
• 
Changed the duration of enrollment from 8 to 12 months.

APPENDIX I  SUMMARY OF CHANGES IN STUDY CFZ013 AMENDMENT 2 
 
 This Summary of Changes outlines noteworthy changes from protocol amendment 1.0 to 
protocol amendment 2.0, and includes rationales for the changes.  Administrative 
updates, typographical and formatting changes were made throughout the protocol.  
Updates have been implemented to align with the current template.  The main purposes 
for revising the CFZ013 (20140241) protocol are as follows: 
 
A Dose-evaluation Component is added for newly diagnosed multiple myeloma 
(NDMM) subjects.  During the conduct of the trial, NDMM subjects were enrolled into 
Dose-expansion Arm 1 (treated at Cohort 2 dosing; Table 2 and Appendix E). 
• When 2 serious adverse events were seen during Cycle 1 in the first 8 NDMM 
subjects, an ad hoc Cohort Safety Review Committee (CSRC) meeting was held.  
The CSRC elected to: 
o continue the study 
o evaluate NDMM subjects in Dose-evaluation cohorts prior to opening 
additional NDMM Dose-expansion cohorts 
o modify Cycle 1 dosing for NDMM subjects as shown in Table 2, Cohort 
4.  After the ad hoc CSRC meeting, investigators were instructed to treat 
NDMM subjects at dosing herein referred to as Cohort 4 dosing. 
• Dose-evaluation enrollment guideline text is modified.  The language was 
broadened, to apply to both relapsed and refractory multiple myeloma RRMM 
Dose-evaluation and the newly added NDMM Dose-evaluation components of the 
trial 
• Autologous stem cell transplant (ASCT) is now allowed for NDMM subjects 
while remaining on trial.  The previous version allowed enrollment of transplant-
eligible NDMM subjects and stem cell harvest but did not allow ASCT for 
subjects on trial.   
• Simplified study schema (Figure 1) 
• Revised blood collection schedule for pharmacokinetics and pharmacodynamics 
for NDMM cohort, to reflect dosing schedule 
• Added dose rationale for new dosing regimen 
• Modified study duration, given delay in enrollment of NDMM subjects  
 
• For treatment guidelines: 
o modified guidelines for thrombotic microangiopathy and Posterior 
Reversible Encephalopathy Syndrome to align with the current 
Carfilzomib Investigator’s Brochure Amgen/Onyx. Carfilzomib 
Investigator’s Brochure. Onyx Therapeutics, Inc. (a wholly owned 
subsidiary of Onyx Pharmaceuticals, Inc., an Amgen Inc. subsidiary).  
o specified guidelines for pulmonary hypertension to align with the current 
Carfilzomib IB

• For study procedures: 
o Added Section 10.1.1 Baseline Procedures 
o revised vital signs collection text to clarify post-dose blood pressure 
collection on treatment days 
o removed peripheral neuropathy assessment from physical examination 
assessments 
o required urine protein electrophoresis with immunofixation for every 
disease assessment 
o specified that local bone marrow pathology assessment will be done to 
evaluate for complete response 
• Modified Appendix C:  removed text referring to subjects without measurable 
serum M-protein, urine M-protein or serum free light chains at baseline, as these 
subjects are not eligible for enrollment. 
• To clarify changes to the protocol, added Appendix E APPENDIX E 
Figures 
from protocol amendment 1 
The following changes were done to align the protocol with the current Amgen Clinical 
Protocol Template: 
• Changed the language in Section 12 (Adverse Events and Serious Adverse 
Events)  
• Modified analysis of the conduct of the study  
• Added publication policy section 
• Added APPENDIX F Additional Safety Assessment Information

APPENDIX I  SUMMARY OF CHANGES IN STUDY CFZ013 AMENDMENT 3 
 This Summary of Changes outlines noteworthy changes from protocol amendment 2.0 to 
protocol amendment 3.0, and includes rationales for the changes.  Administrative 
updates, typographical and formatting changes were made throughout the protocol.  
Updates have been implemented to align with the current template.  The main purposes 
for revising the CFZ013 (20140241) protocol are listed below: 
Protocol amendment 3 specifies the dosing selected for newly diagnosed multiple 
myeloma (NDMM) Dose-expansion Arm 3.  The carfilzomib, lenalidomide, and 
dexamethasone (KRd) dosing for Arm 3 is as follows: carfilzomib 20 mg/m2 on 
Day 1 of Cycle 1, then 56 mg/m2 on Days 8 and 15 of Cycle 1, and Days 1, 8, and 15 
of Cycles 2-18.  Lenalidomide will be given at 25 mg on Days 1-21, and 
dexamethasone at 40 mg on Days 1, 8, 15, 22 of Cycles 1-8, and on Days 1, 8, and 15 
of Cycles 9-18 (see Cohort 1 dosing in Table 2).

The pharmacokinetics (PK) and pharmacodynamics (PDn) sample collection 
schedule was modified to reflect the dosing selected.  Cycle 2 sampling that was 
introduced in protocol amendment 2, in anticipation of a 2-step-up dosing regimen, 
has been removed as it is not required for the dosing selected for Dose-expansion 
Arm 3. 
Two revisions were made in response to the carfilzomib US Prescribing Information 
(USPI) labelling change approved by FDA in November 2016, which required a 
25% dose reduction in patients with mild or moderate hepatic impairment: 
• Table 9 (Treatment Guidelines for Nonhematologic Toxicity) has been 
modified to align with requested changes.  Specifically, NCI Organ 
Dysfunction Working Group definition of mild, moderate and severe hepatic 
impairment were used (Shibata et al, 2013): 
o mild: total bilirubin (>33% direct) > the upper limit of normal (ULN) 
and ≤ 1.5x ULN OR total bilirubin (>33% direct) ≤ ULN and alanine 
aminotransferase (ALT) or aspartate aminotransferase (AST) > ULN;  
o moderate: total bilirubin  .5x ULN and ≤ 3x ULN, any ALT or AST;  
o severe: total bilirubin > 3x ULN, any ALT or AST.   
Subjects with treatment-emergent mild or moderate hepatic impairment, per 
this definition, are to have a 25% carfilzomib dose reduction.  In cases of 
severe hepatic impairment, carfilzomib is to be held.  In moderate or severe 
hepatic impairment, lenalidomide is to be held. 
• Inclusion criteria have been modified in Section 6.1.  Previous protocol 
amendments allowed enrollment of subjects with baseline mild hepatic 
insufficiency.  With protocol amendment 3 (under which only the NDMM 
Dose-expansion Arm 3 subjects will be enrolled), subjects will be required to 
have normal hepatic function.  The intent of this modification is to maximize 
the ability to give full, protocol-specified 20/56 mg/m2 carfilzomib dosing to 
the enrolled NDMM subjects. 
Other minor changes: 
• To maintain internal consistency of the document, Dose-expansion groups 
are uniformly referred to “Arms” with the term “Cohort” reserved for Dose-
evaluation groups.  
• Changed the duration of enrollment from 8 to 12 months.
