Protocol Number:  M14-031
Name of Study Drug:  Venetoclax (ABT-199)
Phase of Development:  3
Name of Active Ingredient:  Not available 
Date of Protocol Synopsis:  16 December 2020
Protocol Title:  A Phase 3, Multicenter, Randomized, Double Blind, Study of Bortezomib and 
Dexamethasone in Combination with Either Venetoclax or Placebo in Subjects with Relapsed or
Refractory Multiple Myeloma Who are Sensitive or Naïve to Proteasome Inhibitors
Objectives:  
The primary objective of the study is to compare the progression-free survival (PFS) between treatment 
arms in subjects with relapsed or refractory multiple myeloma who are considered sensitive or naïve to 
proteasome inhibitors and received 1 to 3 prior lines of therapy for multiple myeloma.
The secondary objectives are to compare, between treatment arms, the following:  Very Good Partial 
Response (VGPR) or better response rate; PFS in subjects with high BCL-2 expression; duration of 
response (DOR); Patient Reported Outcomes (PRO) including Worst Pain (Brief Pain Inventory – Short 
Form [BPI-SF]), Physical Functioning and Global Health Status/Quality of Life (GHS/QoL) (European 
Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core [EORTC 
QLQ-C30]), and Fatigue (Patient Reported Outcomes Measurement Information System [PROMIS] 
Cancer Fatigue Short Form [SF]); overall survival (OS); time to disease progression (TTP); objective 
response rate (ORR); minimal residual disease (MRD) negativity rate; and safety.
Investigators:  Multicenter
Study Sites:  Approximately 120 sites
Study Population:  Adult male and female subjects with relapsed or refractory multiple myeloma who 
are considered sensitive or naïve to proteasome inhibitors, have received 1 to 3 prior lines of therapy for 
multiple myeloma, and have measurable disease per International Myeloma Working Group (IMWG) 
criteria.  
Number of Subjects to be Enrolled:  Approximately 280
Methodology:  
This is a Phase 3, multicenter, randomized, double blind, placebo-controlled, parallel group study.  This 
study is designed to evaluate the efficacy and safety of venetoclax plus bortezomib and dexamethasone 
(Bd) in subjects with relapsed or refractory multiple myeloma who are considered sensitive or naïve to 
proteasome inhibitors and have received 1 to 3 prior lines of therapy for multiple myeloma.  The study 
will consist of three phases:  Screening, Treatment, and Follow-Up.
Serum, plasma, bone marrow aspirate and bone marrow core biopsy tissue will be collected for 
biomarker analysis and exploratory research at designated time points throughout the study.
Screening
Unless otherwise specified, screening procedures must be performed within 21 days prior to 
randomization, including disease assessments per the IMWG criteria.  Procedures that are completed as 
standard of care within 7 days prior to consent may be considered for screening.  Laboratory tests not 
meeting eligibility criteria can be repeated during the screening period to confirm eligibility.

Methodology (Continued):
Screening (Continued)
Subjects who do not randomize within 21 days of screening will be screen-failed.
Subjects who are screen-failed may be re-screened one additional time.  Subjects who are re-screened 
will be re-consented.  Re-screened subjects will keep their original screening number and will begin the 
screening period once again.  
Once screening procedures are complete and eligibility is confirmed, subjects will be randomized 2:1 to 
one of the following two arms:

Arm 1:  Venetoclax plus Bd

Arm 2:  Placebo plus Bd
Subjects will be stratified based on prior exposure to bortezomib or other proteasome inhibitors 
(proteasome inhibitor-naïve versus proteasome inhibitor-sensitive) and the number of prior lines of 
therapy (1 versus 2 or 3).
Treatment
During Treatment, all subjects will receive venetoclax/placebo orally (PO) once daily (QD) plus Bd as
follows beginning on Cycle 1 Day 1.  Venetoclax/Placebo and dexamethasone should be taken at the site 
on days when bortezomib is administered (Days 1, 4, 8 and 11 of Cycles 1 – 8, and Days 1, 8, 15 and 22 
of Cycles 9 and beyond).  On all other days, subjects can self-administer venetoclax/placebo QD.  
Dexamethasone can be self-administered on Days 2, 5, 9 and 12 of Cycles 1 – 8 and Days 2, 9, 16 and 23 
of Cycles 9 and beyond.  Delays of up to 7 days in the initiation of a cycle due to toxicity or scheduling 
issues will be allowed.  Unless otherwise noted, cycle visits may be completed within a window of 
± 1 day provided the 72-hour bortezomib requirement is kept.   
Cycles 1 – 8, 21-Day Cycle Length

Venetoclax 800 milligram (mg)/Placebo QD on Days 1 – 21

Bortezomib 1.3 mg/meter (m)2 on Days 1, 4, 8 and 11

Dexamethasone 20 mg on Days 1, 2, 4, 5, 8, 9, 11 and 12
Cycles 9 and Beyond, 35-Day Cycle Length

Venetoclax 800 mg/Placebo QD on Days 1 – 35*

Bortezomib 1.3 mg/m2 on Days 1, 8, 15 and 22**

Dexamethasone 20 mg on Days 1, 2, 8, 9, 15, 16, 22 and 23***
*
Placebo tablet administration will be discontinued for subjects in Arm 2 (Placebo + Bd) once subjects are 
unblinded.
**
Bortezomib dosing frequency may be reduced or discontinued per investigator's decision and institutional 
guidelines once subjects are unblinded.
*** Dexamethasone dosing (frequency and/or dose) may be reduced or discontinued per investigator's decision and 
institutional guidelines once subjects are unblinded.
When unblinding occurs, if subjects from Arm 1 (Venetoclax + Bd) and Arm 2 (Placebo + Bd) are on
dexamethasone monotherapy, they must be discontinued from the study treatment and from the study 
once the Safety Follow-Up Visit is completed.
Study visits will occur on Days 1, 4, 8, and 11 of Cycles 1 – 8.  Study visits during Cycle 9 and beyond 
will occur on Days 1, 8, 15 and 22.

Methodology (Continued):
Treatment (Continued)
Subjects will continue their treatment assignment until documented disease progression per Investigator 
assessment, unacceptable toxicity, withdrawal of consent, or the subject meets other protocol criteria for 
discontinuation (whichever occurs first).  All subjects will have a Treatment Completion Visit (TCV) 
performed when treatment is discontinued unless subject has withdrawn consent to participate in the 
study.
Baseline IMWG assessments will be obtained at Cycle 1 Day 1 prior to first dose of study treatment, 
unless the Screening IMWG assessments were completed within 7 days of Cycle 1 Day 1.  Post-baseline 
IMWG assessments will be performed throughout the study on Day 1 (± 1 week) of every cycle starting 
on Cycle 2 Day 1 and continuing until disease progression per the IMWG criteria, or the subject 
withdraws consent.
In addition to being reviewed by the Investigator and/or qualified site staff, all disease assessment 
information will be sent to an Independent Review Committee (IRC).  Interpretations from the IRC will 
not be sent to the site.
With the completion of the PFS analysis, post-baseline IMWG assessments are no longer required to be 
sent to the IRC and will be reviewed only by the Investigator and/or qualified medical site staff.
Follow-Up
All subjects should have one Safety Follow-Up Visit approximately 30 days after the last dose of study 
treatment.
Subjects who discontinue study treatment for reasons other than progressive disease (e.g., toxicity, 
non-compliance, etc.) or subjects who receive an off protocol new anti-multiple myeloma therapy will 
remain on study and continue to be followed for disease progression per the IMWG criteria every 
4 weeks (± 1 week) following last dose of treatment for the first year, and then every 12 weeks 
(± 1 week) thereafter, until progressive disease (PD) or until the number of Overall Survival (OS) events 
required for the final OS analysis is reached, whichever occurs first.  Subjects who experience an event of 
disease progression or withdraw from study will continue to be followed for survival and post treatment 
information until the number of OS events required for the final OS analysis is reached.
Survival information and post treatment information will be collected approximately every 12 weeks (or 
as needed to allow for more frequent data collection) until death, the subject is lost to follow-up, the 
subject withdraws consent, the number of OS events required for the final OS analysis is reached, or the 
study is terminated by AbbVie, whichever occurs first.  Non-treatment emergent death (those occurring 
30 days after the final dose of study drug) information will also be collected until the number of OS 
events required for the final OS analysis is reached.  Subject must request to be withdrawn specifically 
from survival follow-up.

Criteria for Evaluation:
Efficacy:
IMWG assessments for clinical response and progressive disease will be done per IMWG criteria, and 
will be used to assess PFS, VGPR or better response rate, DOR, TTP, and ORR.
OS will be evaluated according to survival information (i.e., alive or deceased, and if deceased, date and 
cause of death) and post treatment information (including therapy, dates of therapy and response).
PROs will be evaluated using BPI-SF, EORTC QLQ-C30, European Organization for Research and 
Treatment of Cancer Quality of Life Questionnaire Multiple Myeloma Module (EORTC QLQ-MY20), 
PROMIS Cancer Fatigue SF, and EuroQoL EQ-5D-5L (EQ-5D-5L).
Pharmacokinetic:
Pharmacokinetic (PK) samples will be collected and analyzed for venetoclax and bortezomib (and 
dexamethasone, in subjects enrolled in Japan only).  Venetoclax results may be incorporated into a 
population PK analysis to estimate parameters such as clearance.
Biomarkers:
Biospecimens (serum, plasma, bone marrow aspirate and bone marrow core biopsy tissue) will be 
collected to investigate biomarkers.  Types of biomarkers analyzed may include:  BCL-2 family member 
expression, chromosomal abnormalities (Immunoglobulin [Ig] H translocations, amplifications, or 
deletions), and MRD negativity.  Additional biomarkers analyzed may include nucleic acids, proteins, 
lipids or metabolites.  The samples may be analyzed as part of a multi-study assessment of factors 
involved in the response to therapy or the disease state.
Pharmacogenetics:
Deoxyribonucleic Acid (DNA) samples may be analyzed for genetic factors contributing to the response 
to venetoclax in terms of pharmacokinetics, efficacy, tolerability, and safety.

Criteria for Evaluation (Continued):
Safety:
AbbVie will assess adverse events, laboratory data, electrocardiograms (ECG) and vital signs throughout 
the study.  Adverse events intensity and laboratory evaluation changes will be assessed by utilizing 
National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 
Version 4.03.
Statistical Methods:
Efficacy:
Primary Efficacy Endpoint:
The primary efficacy endpoint is PFS.  PFS is defined as the time from randomization to the 
first documented PD or death due to any cause, whichever occurs first.  The primary analysis of PFS will 
be based on data from the IRC's assessment of disease progression.  
A stratified two-sided log-rank test will be used to test PFS.  Two-sided significance level of this test is 
0.05.  The hazards ratio for treatment effect will be estimated and its two-sided 95% confidence interval 
will be provided.  In addition, survivorship functions will be estimated by using Kaplan-Meier product-
limit method.  If reached, median PFS time and its two-sided 95% confidence intervals will be presented 
by treatment group.
Secondary Efficacy Endpoints:
Secondary efficacy endpoints are as follows:  VGPR or better response rate; PROs:  Worst Pain (BPI-
SF), Physical Functioning (EORTC QLQ-C30); OS; PFS in subjects with high BCL-2 expression; DOR; 
TTP; ORR; MRD negativity rate; PROs GHS/QoL (EORTC QLQ-C30), and Fatigue (PROMIS Cancer 
Fatigue SF).
OS is defined as time from randomization to death due to any cause.
VGPR or better response rate is defined as the proportion of subjects with documented Complete 
Response (CR), stringent Complete Response (sCR), or VGPR.
DOR is defined as the time from first documented response (PR or better) to the date of first documented 
PD or death due to multiple myeloma, whichever occurs first.  TTP is defined as the time from 
randomization to the date of first documented PD or death due to multiple myeloma, whichever occurs 
first.  ORR is defined as the proportion of subjects with documented PR or better.
A stratified two-sided (cumulative two-sided α = 0.05) 3-look group sequential log-rank test will be used 
to test OS.  The hazards ratio (HR) for treatment effect will be estimated and its two-sided 95% 
confidence interval will be provided.
VGPR or better response rate and ORR will be analyzed by using Cochran-Mantel-Haenszel test.  
Estimated rates along with corresponding 95% confidence intervals will be presented.
PFS in subjects with high BCL-2 expression, DOR, and TTP will be analyzed by using stratified log-rank 
test.  The hazards ratios for treatment effect will be estimated and two-sided 95% confidence intervals 
will be provided.
For MRD negativity, estimated rates along with corresponding 95% confidence intervals will be 
presented.
Patient-Reported Outcomes:
Worst Pain (BPI-SF), Physical Functioning and GHS/QoL (EORTC QLQ-C30), and Fatigue (PROMIS 
Cancer Fatigue SF) will be analyzed by treatment groups.

Statistical Methods (Continued):
Efficacy (Continued):
Secondary Efficacy Endpoints (Continued):
Statistical Analyses:
The primary analysis of PFS will be performed when approximately 136 PFS events are observed.
Pharmacokinetics:
An analysis of venetoclax plasma concentrations may be performed using a nonlinear mixed effect 
population PK modeling approach.
Biomarkers:
A pre-defined threshold for BCL-2 expression will be utilized to compare median PFS between treatment 
arms in subjects with High BCL-2 expression.  Additionally, biomarker analyses may be explored based 
upon the available data and may not be included in the clinical study report.  Summary tabulations may 
be produced if data from a sufficient number of subjects are collected.
Safety:
Safety will be assessed by evaluating study treatment exposure, adverse events, serious adverse events, 
deaths, and changes in laboratory determinations and vital sign parameters.  Subjects who are 
randomized, but do not receive study drug, will not be included in the analyses of safety.
Sample Size:
For sample size estimation, the median PFS of placebo plus Bd and venetoclax plus Bd is assumed to be 
9 months and 16.25 months, respectively (HR = 0.554, under the assumption of proportionality).  
Two-sided log-rank test with a two-sided type I error rate of α = 0.05 and a power of ≥ 90% is used.  
Under the assumptions above and using a 2:1 randomization ratio to the two arms (venetoclax plus Bd 
versus placebo plus Bd) a total of 136 PFS events per IRC assessment are required.  To observe 136 PFS 
events per IRC assessment, approximately 280 subjects will be randomized.

Introduction
3.1
Multiple Myeloma (MM)
Multiple myeloma (MM) represents 1% of all cancers and about 13% of all hematologic 
malignancies.  Approximately 86,000 new cases of MM occur annually worldwide.1  The 
incidence of MM is 6.7 cases per 100,000 in the United States and 6.0 cases per 
100,000 per year in Europe, with an age-adjusted mortality rate of 3.4 cases per 
100,000 per year.2,3  For 2014, it has been estimated that 24,000 new cases of MM would 
be diagnosed and 11,000 deaths would occur in the United States alone.4
Patients with MM experience a number of disease-related symptoms and effects, such as 
bone destruction and bone pain, bone marrow failure, renal failure, and 
immunodeficiency, leading to deterioration in health-related quality of life (HRQoL).5  In 
a study comparing HRQoL data from survivors of 13 uncommon cancers from individuals 
without cancer, survivors of MM and pancreatic cancer were among those with the lowest 
HRQoL scores.6
The treatment paradigms and outcomes for patients with MM have markedly changed in 
the past decade with the introduction of several new, more effective and less toxic 
therapies, doubling the median overall survival from 3 years to 6 years.3,7  Nevertheless, 
significant unmet needs remain for the treatment of MM, as this disease has no cure to 
date, and current therapies can only slow disease progression, prolong survival, and 
minimize symptoms.  In fact, the majority of patients with myeloma will relapse or 
become refractory, regardless of the line of therapy, which is associated with high 
morbidity and mortality.  Additionally, the remission duration in relapsed myeloma 
decreases with each regimen.
Various treatment options are available in case of relapse, ranging from conventional 
cytostatic agents such as melphalan or cyclophosphamide, and steroids to novel classes of 
drugs, including Immunomodulatory Thalidomide Derivative Compounds (IMiDs), 
proteasome inhibitors, histone deacetylase (HDAC) inhibitors, and monoclonal antibodies

(anti-CS1, anti-CD38).  Most recommended treatment protocols comprise variable 
combinations of these drugs.  The proteasome inhibitor bortezomib combined with 
dexamethasone (Bd) has proven therapeutic value and is considered to be one of the 
standards of care in the treatment of relapsed multiple myeloma.3,8
3.2
BCL-2 Family of Proteins in Multiple Myeloma
There are two main pathways of apoptosis or programmed cell death, namely the 
extrinsic, or death receptor-mediated pathway, and the intrinsic or mitochondrial pathway.  
The intrinsic pathway is regulated by a delicate balance between anti-apoptotic (BCL-2, 
BCL-XL, BCL-W, BFL-1/A1, and MCL-1) and pro-apoptotic (BAX, BAK, BID, 
BCL-xS, BAD, BIK, BIM, HRK, and NOXA) BCL-2 family proteins.  Normally, BAX 
and BAK are sequestered by the anti-apoptotic proteins BCL-2, BCL-XL, and/or MCL-1 
and prevented from interacting with mitochondria.  
Plasma cells are typically geared towards long-term survival and have low apoptotic rates, 
likely due to high levels of anti-apoptotic proteins such as BCL-2 and MCL-1.  
Dysregulation of apoptotic pathways in these cells, often via aberrant BCL-2 and/or 
MCL-1 overexpression, is thought to play a major role in the development and 
progression of multiple myeloma.  Antagonizing BCL-2 and MCL-1 function to induce 
apoptosis is thus a compelling therapeutic approach in multiple myeloma, and can be 
achieved by combining the BCL-2-selective inhibitor venetoclax with the proteasome 
inhibitor bortezomib, which has been demonstrated to upregulate the MCL-1-neutralizing
protein NOXA.
3.3
Nonclinical Pharmacology and Clinical Data
Venetoclax Activity
Venetoclax is a novel, orally bioavailable small molecule inhibitor of BCL-2 (Ki
< 0.010 nanomolar [nM]) with much lower affinity for BCL-XL and BCL-W (> 480-fold 
and > 2,000-fold lower affinity, respectively).  In vitro, venetoclax has demonstrated cell 
killing activity against MM cell lines and primary patient samples.  The sensitivity of MM

29
cell lines correlated most closely with their BCL2/MCL1 messenger ribonucleic acid 
(mRNA) expression ratio, with the most sensitive cell lines expressing high levels of 
BCL2 relative to MCL1.  MM cell lines bearing the t(11;14) translocation were 
particularly sensitive to venetoclax (6 of 8 cell lines with a lethal dose 50% [LD50] 
< 100 nM, median LD50 = 10 nM).  Similar trends were observed for MM primary 
samples treated ex vivo with venetoclax, with four of five t(11;14)-positive samples being 
especially sensitive (LD50 < 100 nM).9
Venetoclax has also shown efficacy in multiple xenograft models of MM when combined 
with bortezomib.  This combination was clearly more efficacious than either agent alone 
in the t(14;16) model RPMI-8226 and the t(4;14) models H929, KMS-11 and OPM-2, 
with improved tumor growth inhibition and tumor growth delay observed in each case.  
Combination efficacy correlated with an ability of bortezomib to upregulate the 
MCL-1-inhibiting protein NOXA.

clinical data with venetoclax in multiple myeloma) can be found in the most current 
version of the Investigator's Brochure.12
Venetoclax Nonclinical Toxicology and Pharmacology
Primary venetoclax-related toxicities were effects on the hematologic system (decreased 
lymphocytes and red blood cell mass in mice, rats and dogs), the male reproductive 
system (testicular germ cell depletion in dogs), and embryo-fetal toxicity in mice.
Decreases in lymphocytes and red blood cell (RBC) mass were dose-related and 
reversible.  Lymphocyte decreases are consistent with the expected pharmacology of 
venetoclax (a selective Bcl-2 inhibitor)10 and, when sustained over periods of 6 to 
9 months in chronic toxicology studies, were not associated with opportunistic infections.  
B-cells were the most sensitive lymphocyte subtype based on the magnitude of decrease 
(> 90%) and/or the length of time required for recovery (up to 18 weeks).  Decreased 
RBC mass, typified by decreased hemoglobin, was adverse only at the high dosages

administered (–21% in mice at 600 milligram [mg]/kilogram [kg]/day and –23% in dogs 
at 150 mg/kg/day).  Thrombocytopenia has not been observed in toxicology studies in 
mice and dogs.  These findings are consistent with venetoclax as a BCL-2 specific 
(BCL-XL sparing) inhibitor.  Venetoclax produced adverse, non-dose-related microscopic 
findings of testicular germ cell loss in dogs at all dosages tested and did not demonstrate 
reversibility.  In the mouse embryo-fetal development study, increased post-implantation 
loss and decreased fetal body weights occurred at the highest dosage administered 
(150 mg/kg/day); the no-observed-adverse-effect-level (NOAEL) was defined at the 
mid-dose of 50 mg/kg/day.  Venetoclax was not teratogenic in mice or rabbits, and there 
were no other effects on development or fertility.
Other noteworthy findings with venetoclax were epithelial single cell necrosis in multiple 
tissues and hair coat color change, both in dogs.  Single cell necrosis was observed in the 
gallbladder, exocrine pancreas, epididymides, prostate, and stomach.  These findings were 
not adverse based on minimal to mild severity and no microscopic evidence of loss of 
mucosal integrity.  Partial to complete reversibility was observed.
Venetoclax was tested in a battery of safety pharmacology assays, and produced no 
effects in the central nervous system (CNS)/neurobehavioral or respiratory studies in mice 
at oral doses up to and including the highest oral dose of 600 mg/kg.  In conscious dogs, 
venetoclax did not produce any cardiovascular effects up to and including the highest oral 
dose of 150 mg/kg (maximum observed plasma concentration [Cmax] = 16 microgram 
[µg]/milliliter [mL]).  At higher plasma concentrations in anesthetized dogs, mild 
decreases in cardiac contractility and cardiac output, and a small increase in QT Interval 
Corrected for Heart Rate (QTc) (8 milliseconds [ms]), were observed.  These effects 
occurred at concentrations > 3- to 5-fold above peak clinical concentrations at the 
maximum dose and were not considered to be clinically relevant due to their small 
magnitude and lack of a dose-dependent relationship.  On the basis of nonclinical safety 
pharmacology and toxicology evaluations of venetoclax, and on the basis of nonclinical 
and human studies of related anti-apoptotic BCL-2 family protein inhibitors, potential 
mechanism-based toxicities may include lymphopenia and neutropenia,11 signs of tumor

lysis, reduction in red cell mass, decreased spermatogenesis, skin swelling, and hair 
hypopigmentation.
A detailed discussion of the preclinical toxicology, metabolism, and pharmacology can be 
found in the most current version of the Investigator's Brochure.12
Clinical Pharmacology
Following oral administration, the maximum plasma concentration of venetoclax is 
generally obtained by 5 to 8 hours.  The harmonic mean terminal half-life ranges from 
17 to 41 hours following a single oral dose of venetoclax, which supports the proposed 
daily dosing.  In patients with Chronic Lymphocytic Leukemia (CLL), venetoclax showed 
minimal accumulation, and steady-state Area Under the Plasma Concentration-Time 
Curve (AUC) increased proportionally over the dose range of 150 to 800 mg.
Venetoclax has been administered with food in all clinical studies, as food increased the 
bioavailability of venetoclax.  In Non-Hodgkin Lymphoma (NHL) patients, 
administration of venetoclax with low- and high-fat meals increased the venetoclax area 
under the plasma concentration – time curve from time zero to infinity (AUC∞) by 4.3-
and 4.4-fold, respectively, compared to fasting conditions.  Similarly, in healthy subjects, 
venetoclax administration following low-fat and high-fat meals increased venetoclax 
exposure by approximately 3.4- and 5.1- to 5.3-fold, respectively, compared to fasting 
conditions.  Therefore, venetoclax should be administered with food to ensure adequate 
bioavailability.
Venetoclax is highly bound to plasma proteins with unbound fraction < 0.01, and it is 
primarily eliminated as metabolites in feces with negligible renal elimination (< 0.1%).  
M27 was identified as a major metabolite with an inhibitory activity against Bcl-2 that is 
at least 58-fold lower than venetoclax in vitro.  Venetoclax and M27 are predominantly 
metabolized by cytochrome P450 (CYP) 3A4 (CYP3A4) in vitro; 
UDP-glucuronosyltransferases (UGTs) are not involved in the metabolism of venetoclax.  
Venetoclax is also substrate for P-glycoprotein (P-gp) and breast cancer resistance protein 
 

Venetoclax
M14-031 Protocol Amendment 8

32
(BCRP) transporters.  No active uptake of venetoclax was observed in cells 
overexpressing organic anion transporting polypeptide (OATP) 1B1 or OATP1B3.
The effect of ketoconazole, a potent CYP3A inhibitor, on venetoclax pharmacokinetics 
(PK) was evaluated in 12 patients with relapsed or refractory NHL.  Co-administration of 
ketoconazole with venetoclax resulted in a 2.3-fold increase in venetoclax maximum 
observed plasma concentration (Cmax) and a 6.4-fold increase in AUC∞.  The effect of the 
strong CYP3A inducer rifampin on venetoclax PK was evaluated in 12 female patients of 
non-childbearing potential.  Following co-administration of venetoclax with multiple 
doses of rifampin when CYP3A induction effects dominate, venetoclax Cmax and AUC∞
decreased by approximately 42% and 71%, respectively, compared to venetoclax 
administered alone.  Comparing the venetoclax exposure following multiple doses of 
rifampin to that following the first dose of rifampin, venetoclax Cmax and AUC∞decreased 
by approximately 72% and 84%, respectively.  This comparison isolates the effects of 
rifampin CYP3A induction effects from its transporter inhibition effects.
Based on in vitro results, venetoclax was a P-gp, BCRP, and OATP1B1 inhibitor.  It was 
not a potent in vitro inhibitor of CYP3A4, CYP1A2, CYP2B6, or CYP2D6 (IC50
> 30 µM); and it did not induce CYP3A4 or CYP1A2 at concentrations up to 10 µM.  
Venetoclax is also not predicted to cause inhibition of CYP2C19, CYP2C8, CYP2C9, and 
UGT1A1 at clinically relevant concentrations.  It is not an inhibitor of UGT1A4, 
UGT1A6, UGT1A9 and UGT2B7.
Following co-administration of a single dose of venetoclax with warfarin, R- and 
S-warfarin Cmax and AUC∞increased by approximately 18% to 28%.  Relatively low 
variability was observed in warfarin PK.  
No specific clinical trials have been conducted in the subjects with hepatic or renal 
impairment.  No dose adjustment is recommended in patients with mild or moderate 
hepatic or renal (creatinine clearance [CrCl] ≥ 30 mL/min) impairment based on results of 
the population pharmacokinetic analysis.  The analysis indicated no relationship between 
apparent clearance or apparent volume of distribution and hepatic function.  The 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
33
contribution of renal processes to the elimination of venetoclax is negligible, with < 0.1% 
of the dose being recovered in urine.  Additionally, the population PK analysis showed no 
relationship between venetoclax apparent clearance and baseline renal function.  Based on 
the population PK analysis, age, sex, race and weight also do not have an effect on 
venetoclax clearance.
The potential for venetoclax to affect electrocardiogram parameters was evaluated in 
patients with relapsed or refractory CLL or relapsed or refractory NHL.  Results from this 
study showed that at doses through 1200 mg once daily (QD), venetoclax had no effect on 
the QT interval corrected for heart rate using QT Interval Corrected for Heart Rate by 
Fridericia's formula (QTcF), and there was no relationship between venetoclax exposure 
and change in QTcF interval.
Venetoclax Clinical Data
As of 17 September 2015, a total of 102 subjects were dosed in two AbbVie oncology 
Phase 1 studies in multiple myeloma, at doses ranging from 50 mg to 1200 mg.
Study M13-367 is an open-label, multicenter study evaluating the safety, PK and efficacy 
of venetoclax monotherapy given once daily in subjects with relapsed or refractory MM.  
In the dose-escalation (DE) cohorts (3 + 3 design), venetoclax was given orally daily at 
300, 600, 900, or 1200 mg after a 2-week dose ramp-up.  Subjects in the ongoing safety 
expansion (SE) cohort receive 1200 mg daily after ramp-up.  As of 17 September 2015, 
57 subjects were dosed with venetoclax in Study M13-367:  30 from DE cohorts and 
27 from the SE.  
Study M12-901 is an open-label, multicenter study evaluating the safety, PK and efficacy 
of venetoclax when dosed once daily in combination with bortezomib and dexamethasone 
in subjects with relapsed or refractory MM.  As of 17 September 2015, 45 patients were 
dosed with venetoclax in the DE cohorts at doses ranging from 50 mg to 1000 mg.  Dose 
escalation followed a continual reassessment method (CRM) design.  There is no dose

34
ramp-up or lead-in period in this study.  Subjects (N ~ 12) in the planned SE cohort 
receive the recommended Phase 3 dose.
Patients in both studies have been heavily pre-treated, with a median (range) number of 
prior lines of therapy of 4 (1 – 13) and 5 (1 – 13) in Studies M12-901 and M13-367, 
respectively.
Additionally, a small (n ~ 24) Phase 1 clinical trial is also being conducted in Japan to 
evaluate the safety and pharmacokinetic profile of venetoclax monotherapy in Japanese 
subjects with hematological malignancies including multiple myeloma (Study M13-834).
As of 17 September 2015, clinical activity has been observed in both Phase 1 studies 
using the International Myeloma Working Group (IMWG) criteria.13,14  In the venetoclax 
monotherapy Study M13-367, objective responses (partial response [PR] or better) were 
observed in 5 out of 43 evaluable subjects (11.6%).  These responses included 2 complete 
responses [CR] and 3 very good partial responses [VGPR].  Also, 4 of these responses 
were observed in subjects with the t(11;14), who comprised 17 of the evaluable subjects.  
In Study M12-901, objective responses were reported in 21 of 41 evaluable subjects 
(51.2%).  Importantly, the objective response rate (ORR) was 17% (3/18) in subjects 
considered refractory to prior bortezomib therapy, but increased to 71% (12/17) in 
bortezomib-sensitive subjects and 100% (6/6) in bortezomib-naïve subjects, respectively.  
Furthermore, whereas no VGPR or better responses were reported in 
bortezomib-refractory patients, 35% and 83% of the bortezomib-sensitive and 
bortezomib-naïve patients, respectively, experienced VGPR or better responses.  
Preliminary results also indicate that subjects who had received 1 to 3 prior lines of 
therapy had higher ORR (83.3%) and VGPR or better (56%), compared to patients who 
had received 4 – 6 (38.5% ORR) or at least 7 (10% ORR) prior lines of therapy.
As of 17 September 2015, discontinuations in the Phase 1 studies (Studies M13-367 and 
M12-901) were between 67% – 69%, and mostly related to progressive disease (PD) 
(61% – 77% of discontinuations).  Few discontinuations occurred due to adverse events 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
35
(AE) not related to PD (7% – 12% of discontinuations).  In Study M12-901, 
treatment-emergent AEs occurring in ≥ 20% of the subjects were constipation (40%), 
diarrhea (38%), thrombocytopenia (33%), insomnia (29%), asthenia (27%), peripheral 
neuropathy (27%), anemia (24%), nausea (24%), dyspnea (22%), peripheral edema 
(22%), and fatigue (20%).  Grade 3 or 4 AEs in ≥ 10% of subjects in Study M12-901 were 
thrombocytopenia (22%), and anemia (16%).  Serious Adverse Events (SAEs) occurred in 
19 subjects (42%), none considered related to venetoclax.  In ≥ 2 patients, the following 
SAEs were noted:  pneumonia (n = 3), cardiac failure, embolism, pyrexia, sepsis, 
respiratory failure, and thrombocytopenia (n = 2 each).  The safety profile in 
Study M13-367 was similar, but with fewer sensory peripheral neuropathy (6.3%) and no 
AE of insomnia reported.  In Study M13-367, SAEs occurred in 14 subjects (29%).  SAEs 
in ≥ 2 pts were sepsis (n = 3), cough, pyrexia, pneumonia, and malignant neoplasm 
progression (2 each).  The SAEs of anemia, supraventricular tachycardia and upper 
abdominal pain (1 of each) were considered possibly related to venetoclax.  
Tumor Lysis Syndrome (TLS) was identified as an important risk when initiating 
venetoclax in CLL patients even with initial doses of 20 and 50 mg doses.  To-date, in the 
dose-finding Phase 1 study, TLS has not been observed in MM patients receiving 
venetoclax at initial doses of 50 to 1200 mg.  
In addition, due to potential mechanism-based toxicities of lymphopenia and neutropenia, 
serious infections are a potential risk with venetoclax therapy.

(including clinical data with venetoclax in multiple myeloma) can be found in the most 
current version of the Investigator's Brochure.12
Rationale for Studying Venetoclax with Bortezomib and Dexamethasone in Multiple 
Myeloma Subjects 
It is hypothesized that multiple myeloma cells expressing high levels of BCL-2 and low 
levels of MCL-1 would be more susceptible to BCL-inhibition and induction of cell death 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
36
by venetoclax.  High MCL-1 expression may drive resistance to BCL-inhibition in 
myeloma cells, as MCL-1 is also an important anti-apoptotic molecule.  In this study, the 
addition of bortezomib is especially attractive due to its ability to upregulate the MCL-1 
inhibitor NOXA.  Combination efficacy in the nonclinical setting corresponded with 
bortezomib-mediated NOXA upregulation and disruption of BCL-2-BIM complexes 
driven by venetoclax.  Clinical efficacy data from the Phase 1 combination therapy study 
of venetoclax plus Bd support the hypothesis, with high rates of PR and better in subjects 
that are sensitive or naïve to bortezomib therapy.  
Additional information on venetoclax clinical pharmacology and clinical data can be 
found in the most current version of the Investigator's Brochure.12
3.4
Differences Statement
The current study is the first randomized, double-blind, multicenter Phase 3 study 
comparing venetoclax plus Bd versus placebo plus Bd in relapsed or refractory multiple 
myeloma subjects.
3.5
Benefits and Risks
Despite therapeutic advances, MM remains essentially incurable, associated with high 
morbidity and mortality, and even with the best available approved agents, all patients 
will eventually relapse.  Furthermore, the remission duration in relapsed myeloma 
decreases with each regimen.
Based on evidence of clinically meaningful activity observed in Phase 1 studies with 
venetoclax given as a single agent and when it is combined with the Bd regimen, it is 
anticipated subjects in the investigational arm may benefit from the combined treatment.
Additionally, all subjects randomized in this trial have already progressed on between 1 to 
3 prior lines of therapy and will receive an anti-myeloma regimen of Bd that has proven 
therapeutic value and is a worldwide standard of care.  The safety and efficacy profile of 
Bd has been established in multiple Phase 3 clinical trials.15-18
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
37
Guidance on dose management of Bd is based on the bortezomib prescribing information 
and current standard of care.  
As of 17 September 2015, the safety profile of venetoclax as a monotherapy or plus Bd in 
subjects with relapsed or refractory MM has been consistent with its mechanism of action 
and the background disease in this population.  Based on nonclinical toxicology and 
clinical studies with venetoclax, toxicities may include lymphopenia, neutropenia, anemia 
and gastrointestinal adverse events.  The rate of peripheral neuropathy in Study M12-901 
is in the expected range of a bortezomib-based regimen.  Additionally, no cases of TLS 
have been reported in the Phase 1 studies with venetoclax in MM.  An independent data 
monitoring committee (IDMC) will regularly review safety and efficacy data of treated 
subjects in this study.
The safety and efficacy data to date of venetoclax plus Bd from the Phase 1 study 
supports further evaluation of this combination in subjects with relapsed or refractory 
multiple myeloma.  
Following the study's primary analysis, recommendations for antibiotic prophylaxis and 
dose interruption/reduction for subjects receiving venetoclax/placebo in combination with 
proteasome inhibitors have been implemented (see Section 5.2.4.1, Section 6.1.7.1 and 
Section 6.2.1 - Table 8).  Additionally, recommendations for pneumococcal and influenza 
vaccinations applicable for subjects on study treatment have been implemented (see 
Section 5.2.4.1).
Additional information on venetoclax clinical pharmacology and clinical data (including 
clinical data with venetoclax in multiple myeloma) can be found in the most current 
version of the Investigator's Brochure.12
Considering the coronavirus (COVID-19) pandemic, the benefit and risk to subjects 
participating in this study has been re-evaluated.  Subjects receiving venetoclax, 
bortezomib, and dexamethasone may be at an increased risk for COVID-19 infection or 
experience serious illness if infected.  Management of these adverse events will be made 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
38
on a case-by-case basis with consideration of benefit/risk.  However, based on the 
population and disease being studied and the anticipation that COVID-19 related risks are 
not expected to differ substantially between study subjects and the broader population of 
subjects receiving treatment for multiple myeloma, no change to the benefit/risk balance 
for subjects in this study is expected.

Study Objectives
The primary objective of the study is to compare PFS based on the IMWG Criteria,13,14 as 
determined by an Independent Review Committee (IRC) between treatment arms in 
subjects with relapsed or refractory multiple myeloma who are considered sensitive or 
naïve to proteasome inhibitors and received 1 to 3 prior lines of therapy for multiple 
myeloma.
The secondary objectives are to compare, between treatment arms, the following:  VGPR 
or better response rate; progression free survival (PFS) in subjects with high BCL-2 
expression; duration of response (DOR); patient reported outcomes (PRO) including 
Worst Pain (Brief Pain Inventory – Short Form [BPI-SF]), Physical Functioning and 
Global Health Status (GHS)/Quality of Life (QoL) (European Organization for Research 
and Treatment of Cancer Quality of Life Questionnaire Core [EORTC QLQ-C30]), and 
Fatigue (Patient Reported Outcomes Measurement Information System [PROMIS] Cancer 
Fatigue Short Form [SF]); overall survival (OS); time to progression (TTP); ORR; 
minimal residual disease (MRD) negativity rate; and safety.
The tertiary objectives of the study are to assess clinical benefit rate (CBR), disease 
control rate (DCR), time to response (TTR), time to next treatment (TNT), other PRO 
endpoints (remaining subscales/items from BPI-SF, EORTC QLQ-C30, European 
Organization for Research and Treatment of Cancer Quality of Life Questionnaire 
Multiple Myeloma Module [EORTC QLQ-MY20], and Euroqol EQ-5D-5L), and a 
preliminary assessment of potential biomarkers for association with PK, safety and 
efficacy.

Investigational Plan
5.1
Overall Study Design and Plan:  Description
This is a Phase 3, multicenter, randomized, double blind, placebo-controlled, parallel 
group study.  This study is designed to evaluate the efficacy and safety of venetoclax plus 
Bd in subjects with relapsed or refractory multiple myeloma who are considered sensitive 
or naïve to proteasome inhibitors and received 1 to 3 prior lines of therapy for MM.  
Approximately 280 subjects at approximately 120 sites will be randomized in a 2:1 ratio 
to receive an oral daily dose of either venetoclax 800 mg or placebo plus Bd, respectively.  
The study is designed to meet scientific and regulatory objectives without enrolling an 
undue number of subjects in alignment with ethical considerations.  Therefore, if the 
target number of subjects has been enrolled, there is a possibility that additional subjects 
in screening will not be enrolled.
The study will consist of the following three phases:
●
Screening:  Study assessments performed prior to randomization, including 
randomization;
●
Treatment:  Study assessments performed from first dose through the 
Treatment Completion Visit (TCV);
●
Follow-Up:  Includes the 30 Day Safety Follow-Up Visit.  Also includes 
IMWG assessments performed after the TCV and survival and post-treatment 
information collected from the date of disease progression until death, subject 
is lost to follow-up, the number of OS events required for the final OS analysis 
is reached, or until study termination by AbbVie.
Screening
Unless otherwise specified, screening assessments must be performed within 21 days 
prior to randomization (see Appendix D and Appendix H for all screening assessments).  
Procedures that are completed as standard of care within 7 days prior to consent may be 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
40
considered for screening.  Laboratory tests not meeting eligibility criteria can be repeated 
during the screening period to confirm eligibility.
Subjects who do not randomize within 21 days of screening will be screen-failed. 
Subjects who are screen-failed may be re-screened one additional time.  Subjects who are 
re-screened will be re-consented.  Re-screened subjects will keep their original screening 
number and will begin the screening period once again.  
Once screening procedures are completed and eligibility is confirmed, subjects will be 
randomized 2:1 to one of the following two arms:
●
Arm 1:  Venetoclax plus Bd;
●
Arm 2:  Placebo plus Bd.
Subjects will be stratified based on prior exposure to bortezomib or other proteasome 
inhibitors (proteasome inhibitor-naïve versus proteasome inhibitor-sensitive) and the 
number of prior lines of therapy (1 versus 2 or 3).
Treatment
Subject treatment must start within 5 days after randomization.  Unless otherwise noted, 
cycle visits may be completed within a window of ± 1 day provided the 72-hour 
bortezomib requirement is kept.  If unable to dose with bortezomib within this allowed 
window, then the cycle visit must be skipped.  A delay of up to 7 days is acceptable for 
Cycle X Day 1 visits, beginning at Cycle 2 Day 1, due to toxicity or scheduling issues.
During Treatment, all assessments must be performed on the day of the specified visit 
unless a time window is specified in the schedule of assessments (Appendix E, 
Appendix F, and Appendix H).  Allowed modifications due to COVID-19 are detailed in 
Section 5.3.1.1.

41
All eligible subjects will receive venetoclax/placebo orally (PO) once daily (QD) plus Bd 
as follows beginning on Cycle 1 Day 1.  Subjects will be provided with dosing diaries to 
document Venetoclax/Placebo and Dexamethasone dosing compliance beginning at 
Cycle 1 and continuing until discontinuation.  Subjects in Arm 2 (Placebo + Bd) who 
remain on study after being unblinded, will only need to document Dexamethasone 
dosing compliance in their subject dosing diaries.  The subject dosing diaries should be 
reviewed by the Investigator at each clinic visit to assess compliance.  Compliance is 
defined as adhering to the study treatment dosing at least 80% of the time.  Subjects who 
are noncompliant will need to be re-educated by the Investigator and documentation of the 
re-education added to the source documents.
Due to the COVID-19 pandemic, subject visits may be conducted via phone or video 
conference.  In these situations, subject diaries can be couriered to subjects along with 
study drug. Adverse events, concomitant medications and dosing compliance listed in the 
diaries shall be verbally shared with site if a phone or video conference visit occurs 
Diaries should be returned to the study site when the subject is able to visit the site next, 
and appropriately filed with the subject's source documents for this study.

Venetoclax/Placebo will be administered as described in Section 5.5.1.  Note:  Consider 
TLS prophylaxis with oral hydration (at least 1 – 2 liters, as tolerable, each day) in all 
subjects at least 72 hours prior to the first day of dosing with venetoclax/placebo plus Bd 
and continue as appropriate (refer to Section 6.1.7.2).
Venetoclax/Placebo dose modifications guidelines are provided in Section 6.2.1 and 
Section 6.2.2, Table 8, and Table 9.
Bortezomib will be administered as described in Section 5.5.1.  Bortezomib dose 
modifications guidelines are provided in Section 6.2.3 and Table 10.
Dexamethasone will be administered as described in Section 5.5.1.  Dexamethasone dose 
modifications guidelines are provided in Section 6.2.3 and Table 11.
Subjects will continue their study treatment assignment until disease progression, 
unacceptable toxicity or the subject meets other protocol criteria for discontinuation 
(whichever occurs first).  All subjects will have a TCV performed when treatment is 
discontinued.
Baseline IMWG assessments should be completed at Cycle 1 Day 1 prior to first dose of 
study treatment, unless the Screening IMWG assessments were completed within 7 days 
of Cycle 1 Day 1.  Post-baseline IMWG assessments will be performed on Day 1, 
± 7 days of every cycle starting on Cycle 2 Day 1 (Section 5.3.7.1, Appendix E, 
Appendix F, and per the guidelines of Appendix J).

Disease assessment for each post-baseline IMWG assessment will be performed by the 
Investigator and independently reviewed by a team of multiple myeloma experts (IRC).  
Details regarding the Investigator and IRC assessment progression are provided in 
Section 5.3.7.3.  Interpretations from the IRC will not be sent to sites.
With the completion of the PFS analysis, post-baseline IMWG assessments are no longer 
required to be sent to the IRC and will be reviewed only by the Investigator and/or 
qualified medical site staff.  
An IDMC will periodically review safety and efficacy data.  Once the final Overall 
Survival (OS) analysis is complete (refer to Section 8.1.5.5.2), a final IDMC meeting will 
be held to review safety and efficacy data.  Details regarding the IDMC's review are 
provided in Section 5.5.5.2.
Follow-Up
All subjects should have one Safety Follow-Up Visit approximately 30 days following the 
last dose of study treatment.
Subjects who discontinue study treatment for reasons other than PD (e.g., toxicity, 
non-compliance, etc.) or subjects who receive an off protocol new anti-multiple myeloma 
therapy, will remain on study and continue to be followed for progressive disease per 
IMWG criteria every 4 weeks (± 1 week) following last dose of treatment for the 
first year, and then every 12 weeks (± 1 week) thereafter until PD or until the number of 
OS events required for the final OS analysis is reached, whichever occurs first.
Subjects who experience an event of progressive disease per the IMWG criteria13,14 or 
withdraw from the study will continue to be followed for survival and post-treatment 
information.  Survival information and post-treatment information will be collected 
approximately every 12 weeks (or as needed to allow for more frequent data collection) 
until the endpoint of death, the subject is lost to follow-up, the number of OS events 
required for the final OS analysis is reached, or the study is terminated by AbbVie, 
whichever occurs first.

Start of a new line of treatment after discontinuation of a previous line:  If a 
treatment regimen is discontinued for any reason and a different regimen is 
started, it should be considered a new line of therapy.  A regimen is considered 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
52
to have been discontinued if all the drugs in that given regimen have been 
stopped.  A regimen is not considered to have been discontinued if only some 
of the drugs of the regimen, but not all, have been discontinued.
●
The unplanned addition or substitution of 1 or more drugs in an existing 
regimen:  Unplanned addition of a new drug or switching to a different drug (or 
combination of drugs) due to any reason is considered a new line of therapy.
●
SCT:  In patients undergoing > 1 SCT, except in the case of a planned tandem 
SCT with a predefined interval (such as 3 months), each SCT (autologous, 
allogeneic, or syngeneic) should be considered a new line of therapy regardless 
of whether the conditioning regimen used is the same or different.  Data on type 
of SCT should also be captured.
5.2.4

All subjects must be vaccinated against pneumococcus and receive a yearly influenza 
vaccination (live attenuated vaccines are not allowed), while on study treatment.  It is 
mandated that pneumococcal and yearly influenza vaccinations be administered after 
signing the updated informed consent for all subjects who have not previously received 
the influenza and/or pneumococcal vaccine within the recommended time frame per local 
and/or institutional vaccination guidelines, unless contraindicated, not available, or not 
applicable per local standard of care.
It is recommended that subjects in Progression Follow-up and/or Survival Follow-up 
remain vaccinated against pneumococcus and receive a yearly influenza vaccination at the 
discretion of the investigator.  
Please refer to local label and/or institutional guidelines for additional information (e.g., 
vaccination/booster schedules) and contraindications regarding pneumococcal and

Screening and Treatment Assessments
Subjects will undergo screening procedures within 21 days prior to randomization.  For 
procedures performed at screening and repeated prior to dosing on Cycle 1 Day 1, the 
later procedure(s) will serve as baseline for clinical assessment.  Procedures that are 
completed as standard of care within 7 days of consent may be considered for screening.  
Informed Consent
Signed informed consent will be obtained from the subject or the subject's legally 
acceptable representative before any study-specific procedures are undertaken or before 
any prohibited medications are withheld from the subject in order to participate in this 
study.  Informed consent is also required for optional exploratory research sampling.  
Details about how informed consent will be obtained and documented are provided in 
Section 9.3.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
Due to the COVID-19 pandemic, it is possible that additional protocol modifications not 
outlined in this protocol may become necessary.  If this situation arises, in addition to the 
study informed consent, additional verbal consent may be obtained prior to these 
adaptations or substantial changes in study conduct in accordance with local regulations.  
All informed consent procedures must be documented within the subject's source 
documents.

Proteasome inhibitor naiveté/sensitivity must be assessed and documented per 
the definitions in Inclusion Criterion 2
●
The number of prior lines of therapy must be assessed and documented per the 
definition provided in Inclusion Criterion 3 and Section 5.2.3.
On Cycle 1 Day 1, any changes observed (i.e., abnormal laboratory or vital sign 
assessment) from the screening assessments, prior to dosing, and not considered related to 
study-specific required procedures will be recorded in the subject's medical or oncology 
history, as applicable and will serve as the subject's baseline.  At each subsequent visit, 
the subject's condition will be reviewed and any clinically significant changes from 
baseline will be recorded in the source documents and on the adverse event eCRF.  
Additional guidance for IMWG diagnostic criteria can be found in Appendix C.
Concomitant Medication and AE Assessments
Concomitant medication and AE assessments will be performed prior to the initial dose at 
each subject visit, per Appendix D, Appendix E, Appendix F, and Appendix G.

COVID-19 Pandemic-Related Acceptable Protocol Modification:
Due to the COVID-19 pandemic, concomitant medication and adverse event assessment 
visits may be conducted via phone or video conference. Additional guidance for the 
reporting of COVID-19 adverse events (including the capture of specific signs/symptoms 
of infection and testing results) can be found in Section 6.1.5.
Physical Examination
Physical examinations (full and targeted exams), including body weight, will be 
performed per Appendix D, Appendix E, Appendix F, and Appendix G.  The targeted 
physical exam includes an assessment of heart, lung, and abdomen, and any body system, 
guided by the examiner's observations or subject complaints on new or changed 
conditions, symptoms, or concerns.  Target exams can be performed by the Principal 
Investigator (PI) or delegated to qualified medical staff (e.g., a sub-Investigator, nurse, 
etc.).
If the screening physical examination is performed within 7 days of Cycle 1 Day 1, it is 
not required to repeat the exam on Cycle 1 Day 1 unless clinically indicated.  Physical 
examinations after screening may be performed within 72 hours before or after the 
scheduled visit.  Clinically significant changes from baseline will be documented in the 
source documentation and eCRFs as adverse events.
Height will be measured at the Screening Visit only.  For height and weight, subject 
should not wear shoes.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
Due to the COVID-19 pandemic, subject visits may be conducted via phone or video 
conference.  In these situations, body weight may be collected by the subject or caregiver 
as needed, and physical exam may be performed by another licensed practitioner.

Vital Signs
Vital signs will be performed at each visit, per Appendix D, Appendix E, Appendix F, and 
Appendix G.  Vital sign determinations include sitting blood pressure, heart rate, 
respiratory rate, and body temperature.  Vital signs should be measured prior to blood 
collections and prior to dosing with venetoclax/placebo and Bd.  It is recommended that 
vitals should be assessed after the subject has been seated quietly for at least 5 minutes.   
COVID-19 Pandemic-Related Acceptable Protocol Modification:
Due to the COVID-19 pandemic, subject visits may be conducted via phone or video 
conference.  In these situations, vital signs may be obtained by another licensed 
practitioner, or collected by the subject or caregiver as needed.

COVID-19 Pandemic-Related Acceptable Protocol Modification:
Due to the COVID-19 pandemic, subject visits may be conducted via phone or video 
conference.  If subjects are unable to be assessed by the study site, ECOG performance 
status may be performed by another licensed practitioner.
Patient-Reported Outcome (PRO) Assessments
PRO assessments include BPI-SF, EORTC QLQ-C30, EORTC QLC-MY20, PROMIS 
Cancer Fatigue SF, and EQ-5D-5L.  These assessments will be collected per Appendix D, 
Appendix E, and Appendix F throughout the trial until the final OS analysis.  Once the 
number of OS events required for the final OS analysis is reached, PRO assessments will 
no longer be collected.
Subjects may complete all baseline PRO assessments within 72 hours prior to the 
first dose of venetoclax/placebo.  It is required that PRO assessments be completed prior 
to any other clinical assessments and prior to dosing for subsequent cycle visits.  If a PRO 
assessment is collected on a non-protocol required visit date, as requested per 
Appendix D, Appendix E and Appendix F, this PRO assessment may be reclassified.
BPI-SF
The BPI-SF is a pain-specific measure developed to assess patient-reported severity (or 
intensity) of pain (4 items) and the impact of pain on daily functioning (7 items) in 
patients with cancer pain.21  The four pain severity items assess pain at its "worst," "least,"
"average," and "now" (current pain).  For these items, patients are asked to rate their pain 
on an 11-point numeric rating scale with anchors of 0 (no pain) and 10 (pain as bad as you 
can imagine).  The BPI "worst" pain severity item has been shown to be reliable and valid 
for use as a single item.22  The BPI-SF also includes questions to measure the interference 
of pain in the patient's daily life, including general activity, mood, ability to walk, normal 
work both outside the home and housework, relations to other people, sleep, as well as 
enjoyment of life.  For these items, patients are asked to describe the extent to which pain 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
64
has interfered on an 11-point numeric rating scale with anchors of 0 (does not interfere) to 
10 (completely interferes).
EORTC QLQ-C30
HRQoL and symptoms will be assessed with the EORTC-QLQ-C30 version 3.23  The 
QLQ-C30 is a 30-item subject self-report questionnaire composed of both multi-item and 
single scales, including five functional scales (physical, role, emotional, social, and 
cognitive), three symptom scales (fatigue, nausea and vomiting, and pain), a global health 
status/quality of life scale, and six single items (dyspnea, insomnia, appetite loss, 
constipation, diarrhea, and financial difficulties).  Subjects rate items on a four-point 
scale, with 1 as "not at all" and 4 as "very much."  The QLQ-C30 was developed and 
validated for use in a cancer patient population, and its reliability and validity is highly 
consistent across different language-cultural groups.
EORTC QLQ-MY20
The EORTC QLQ-MY20 was developed as an additional module for the QLQ-C30 and is 
composed of 20 multiple myeloma specific items.24  The QLQ-MY20 includes scales for 
disease symptoms, side effects of treatment, future perspective, and body image.  Values 
for each scale range from 0 to 100.  Subjects rate items on a four-point scale, with 1 as 
"not at all" and 4 as "very much."  The QLQ-MY20 is a reliable and valid instrument for 
measuring quality of life in myeloma patients.
PROMIS Cancer Fatigue SF
The PROMIS® is a system of highly reliable, precise measures of patient-reported health 
status for physical, mental, and social well-being.25  PROMIS instruments measure 
concepts such as pain, fatigue, physical function, depression, anxiety and social function.  
Fatigue will be assessed using the PROMIS Cancer Fatigue SF that has been developed 
for use in oncology populations.26,27  PROMIS Cancer Fatigue SF is a seven item 
questionnaire that assesses the impact and experience of fatigue over the past 7 days.  All 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
65
questions employ the following five response options:  1 = Not at all, 2 = A little bit, 3 = 
Somewhat, 4 = Quite a bit, and 5 = Very much.
EQ-5D-5L
The EQ-5D-5L is a generic preference instrument that has been validated in numerous 
populations.28  The EQ-5D-5L has five dimensions:  mobility, self-care, usual activities, 
pain/discomfort and anxiety/depression.  These dimensions are measured on a five level 
scale:  no problems, slight problems, moderate problems, severe problems, and extreme 
problems.  The EQ-5D-5L also contains a visual analog scale (VAS) to assess the 
subject's overall health.

COVID-19 Pandemic-Related Acceptable Protocol Modification:
Due to the COVID-19 pandemic, subject visits may be conducted via phone or video 
conference.  All PROs are eligible for completion by interview at such visits; however, if 
it is not possible to complete all PROs during the telephone interview, the PRO 
completion prioritization is as follows (highest to lowest priority): EORTC QLQ-C30, 
EORTC QLQ-MY20, EQ-5D-5L, PROMIS and BPI-SF.  In this situation, the interviewer 
properly delegated for this assessment will read the PRO questions and response options 
to the subject and record the subject responses either on paper or directly into the 
electronic web-based system.  If subject responses are recorded on paper, the Subject ID 
number, visit identification, date and time that each PRO was started and completed 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
66
should be recorded along with the interviewer's name on each page of the paper screen 
report and recorded in the source.  In both cases, the site must also record in the source 
that the PRO data collection was performed remotely along with who collected the 
information.  The subject's ability to view the PRO to understand the questions and 
response options should be preserved.  Sites may share the questionnaire by 
videoconference or send the questionnaires (email or hard copy) to the subjects to allow 
them to read/understand the questions and responses when the subject is providing 
responses over the phone.
Cardiac Assessments
Cardiac assessments will be performed using a 12-lead electrocardiogram.  Data from the 
cardiac assessment will be entered into the electronic data capture (EDC) eCRF within 
5 days of report availability.
12-Lead Electrocardiogram (ECG)
A resting 12-lead ECG will be performed per Appendix D and Appendix F.  An 
appropriately qualified physician at the study site (local reader) will determine if any 
findings outside normal physiological variation are clinically significant.  The local 
reading of the ECG will be used by the Investigator for subject safety assessments, 
including adverse event determination and management, and termination of subjects from 
the study.  The local reader will sign and date the ECG tracing and provide a global 
interpretation using the following categories:
●
normal ECG
●
abnormal ECG – not clinically significant (NCS)
●
abnormal ECG – clinically significant (CS)
●
unable to evaluate
All ECGs will be entered into the eCRF.  If the global interpretation is abnormal (CS), the 
Investigator will provide specifics pertaining to the abnormality (e.g., sinus bradycardia, 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
67
arrhythmias).  The corrected QT interval measurement will be documented only if the 
Investigator selects the "prolonged QT" box for an abnormal ECG.  Correction by the 
Bazett formula (QTcB) is suggested for consistency across sites; however, correction by 
other methods may be acceptable based on discussion with the AbbVie TA MD or 
designee.  A copy of any other ECGs will sent to AbbVie, if requested.  The original ECG 
tracing will be retained in the subject's records at the study site.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
In the event the ECG cannot be performed at the study site due to study modifications 
related to the COVID-19 pandemic, the ECG may be completed at other centers providing 
the modality/technique is equivalent.
Lung Disease Risk Assessment – JAPAN and FRANCE ONLY
All subjects enrolled in Japan and France are required to complete the following 
assessments below:
●
a PaO2 by arterial blood gas analysis or SpO2 by percutaneous oxygen 
saturation at screening will be performed
●
a chest CT (high resolution) scan at screening
Tests may be followed during the study visits at the discretion of the investigator.
Pregnancy Test
For female subjects of childbearing potential, pregnancy testing will be performed per 
Appendix D and Appendix E (if necessary).  Pregnancy tests must have a minimal 
sensitivity of ≥ 25 IU/L.
Subjects considered not of childbearing potential must be surgically sterile or 
postmenopausal for at least 1 year.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
68
Clinical Laboratory Tests
All subjects will undergo the laboratory assessments listed in Table 3 per the schedule in 
Appendix D, Appendix E, and Appendix F.
Certified local laboratories will be utilized to process and provide results for the 
hematology and chemistry labs listed in Table 3.  These data will be used for all data 
analysis.  The appropriate certifications will be collected from the local laboratories.  
A certified central laboratory will be utilized to process and provide results for 
coagulation, viral serologies, urinalysis, and special chemistry labs listed in Table 3.  
These data will be used for all data analysis.  The central laboratory will provide 
instructions regarding the collection, processing, handling, and shipping of samples.  
Qualified medical staff at the study site will review, initial, and date all central and local 
laboratory results.  Any laboratory value outside the reference range that is considered 
clinically significant by the Investigator will be followed as appropriate.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
If travel restrictions or other changes in local regulations in light of the COVID-19 
pandemic prevent the subject from having blood drawn for laboratory testing at the study 
site, if possible, arrange for subjects to have laboratory work done at a local laboratory, 
hospital, or other facility.  Local lab results should be obtained along with reference 
ranges and kept within the subjects' source documentation.  Local lab results should be 
reviewed by the investigator as soon as possible and prior to study drug dispensation.
At minimum, safety lab samples [hematology, chemistry, urine pregnancy testing (women 
of childbearing potential), and coagulation panel (when applicable)] should be collected 
and reviewed by the investigator at least once per cycle to have venetoclax/placebo and 
dexamethasone dispensed.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
69
In case of bortezomib, safety lab samples [hematology, chemistry, urine pregnancy testing 
(women of childbearing potential), and coagulation panel (when applicable)] must be 
collected and reviewed by the investigator prior to each bortezomib administration.  If this 
is not possible, bortezomib cannot be dispensed to the subject.
If safety lab samples cannot be collected and related results reviewed by the investigator 
as described above, venetoclax/placebo, dexamethasone or bortezomib cannot be 
dispensed to the subject.
Coagulation
Prothrombin time (PT)/Activated Partial Thromboplastin Time (aPTT) and International 
Normalized Ratio (INR) will be performed per Appendix D.
Coagulation tests will be done for all subjects at screening and only in subjects being 
treated with medication for thromboembolic prophylaxis thereafter on Day 1 of each 
cycle.  Subjects who are not on vitamin K antagonists do not require coagulation tests 
after screening.
Hepatitis Serologies
Samples will be collected to identify Hepatitis B surface antigen (HBsAg), and 
Hepatitis C Virus antibody (HCV ab) antibody and ribonucleic acid (RNA) if HCV ab is 
positive per Appendix D.

a.
For samples analyzed locally, at room temperature, rasburicase causes enzymatic degradation of the uric acid in 
blood/plasma/serum samples potentially resulting in spuriously low plasma uric acid readings.  The following 
special sample handling procedure must be followed to avoid ex vivo uric acid degradation. 
1.
Uric acid must be analyzed in plasma.  Blood must be collected into pre-chilled tubes containing heparin 
anticoagulant.  Immediately immerse plasma samples for uric acid measurement in an ice water bath.  
Plasma samples must be prepared by centrifugation in a pre-cooled centrifuge (4°C).  Finally, the plasma must 
be maintained in an ice water bath and analyzed for uric acid within 4 hours of collection.
b.
SARS-CoV-2 testing performed at local lab for all subjects on study treatment, as clinically indicated per 
Investigator's discretion.
SARS-CoV-2 serology testing (preferred molecular testing e.g., PCR) to be done at any 
timepoint if clinically indicated, per Investigator's decision.  Testing will be performed 
locally.  All COVID-19 test results (both positive and negative), regardless of reason 
administered, must be inserted into EDC on the COVID-19 Status eCRF.

Randomization and Subject (Screening) Number Assignment
Interactive Response Technology (IRT) will be utilized to register (screen, re-screen and 
randomize) subjects on study.  The site will contact the IRT to obtain a screening (subject) 
number once the subject has signed the informed consent and a study-specific procedure 
has been performed (e.g., labs are drawn).  Once the screening number is assigned, if the 
subject is not randomized into the study, the reason for screen failure will be documented 
in the source document and will be captured in the IRT and eCRF.  If the subject is 
randomized into the study, the site will contact the IRT to complete the randomization 
process and obtain the study treatment assignment.  Subject treatment must start within 
5 days after randomization.  All subsequent drug assignments and changes in subject 
status (e.g., treatment completion) will be registered in the IRT.
See Section 5.5.3 for further information.
Dispensing Venetoclax/Placebo
Randomized subjects will receive sufficient quantities of venetoclax/placebo for 21 days 
in each 21-day cycle during the Cycles 1 – 8, and sufficient quantities for 35 days in each 
35-day cycle for Cycles 9 and beyond.  The IRT will assign every bottle of 
venetoclax/placebo to be dispensed to a subject.  Prior to each drug dispensation, site 
personnel must contact IRT for bottle number assignment.  Venetoclax/placebo cannot 
be dispensed without contacting the IRT.  AbbVie or designee will provide specific 
instructions on the use of IRT.
Subjects will be provided with venetoclax/placebo self-administration instructions.  
Subjects will be instructed to store venetoclax/placebo according to specific directions 
included in Section 5.5.2.2.  Subjects are required to return bottles of venetoclax or 
placebo (empty, partially filled, or full) to the study site prior to each cycle and at the 
TCV.
Subjects in Arm 2 (Placebo + Bd) who remain in the study once unblinded, will no longer 
be required to take placebo tablets.

5.3.1.1.2
Follow-Up
After treatment has ended, subjects will be followed for post-therapy information, overall 
survival, non-treatment emergent death information, and progressive disease (if 
applicable).  
At the time the number of OS events required for the final OS analysis is reached, subjects 
will not be followed for post-therapy information, overall survival, non-treatment 
emergent death information, and progressive disease (if applicable) after treatment has 
ended and will be discontinued from the study.
Overall Survival
Survival (i.e., alive or deceased, and if deceased, the date and cause of death) and post 
treatment information will be collected on the appropriate eCRF approximately every 
12 weeks (or as requested by sponsor to support data analysis) beginning on the date of 
progression or discontinuation and continuing either until the endpoint of death, until the 
subject is lost to follow-up, subject withdraws consent, the number of OS events required 
for the final OS analysis is reached, or until study termination by AbbVie, whichever 
occurs first.  The following will be collected for post treatment information:
●
Name(s) of post-therapy regimens
●
Post-therapy dates of initiation and completion
Non-Treatment Emergent Death Collection
After the end of the AE reporting period (in this instance 30 days after the final dose of 
study drug), all deaths reported until the number of OS events required for the final OS 
analysis is reached, including any relevant clinical information leading to the death, 
regardless of cause, should be reported through use of the Non-Treatment Emergent Death 
eCRFs.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
73
Additionally, retrospective relevant clinical information on non-treatment emergent deaths 
which already occurred will be collected from sites that have obtained IRB/EC approval 
to use a waiver of consent to collect such information.  Non-Treatment Emergent Death 
information collected retrospectively should also be recorded on Non-Treatment 
Emergent Death eCRFs.
Non-Treatment Emergent Death information related to deaths reported immediately after 
the number of OS events required for the final OS analysis is reached will no longer be 
collected.
Progressive Disease Assessment
Subjects who discontinue the study treatment for reasons other than PD, even after receipt 
of new anti-multiple myeloma treatment, will be assessed for disease progression (IMWG 
assessment) every 4 weeks (± 1 week) for 1 year following the last dose of study 
treatment, and then every 12 weeks (± 1 week) thereafter until PD.  After PD, the subject 
will continue to be followed for Overall Survival until the number of OS events required 
for the final OS analysis is reached.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
In the event the subject cannot visit the study site for central laboratory and/or research 
sample collection for reasons related to the COVID-19 pandemic, a local accredited 
laboratory may be used to manage subject disease assessment.  Local lab results should be 
obtained along with reference ranges and kept within the subjects' source documentation.  
Local lab results should be reviewed by the investigator as soon as possible.  Additionally, 
the study site should contact the subject by phone or video conference to assess for post-
study myeloma therapy as per Appendix G.  This discussion shall be documented in the 
source documents.

Meals and Dietary Requirements
Each dose of venetoclax/placebo will be taken orally once daily with approximately 
240 mL of water within 30 minutes after the completion of breakfast or subject's 
first meal of the day.  Tablets must be swallowed whole and must not be broken, chewed, 
or crushed.
On days that pre-dose PK sampling is required, venetoclax/placebo dosing will occur in 
the morning at the clinic to facilitate PK sampling. 
Subjects may not consume the following:  grapefruit or grapefruit products, Seville 
oranges (including marmalade containing Seville oranges) or starfruit within the 3-day 
period prior to the first study treatment administration and until the last day of treatment is 
completed due to possible CYP3A mediated metabolic interaction.  It is expected that 
sites record if grapefruit products are consumed by the subject during the study.
5.3.1.3
Collection and Handling of Biomarker and Exploratory 
Research Samples
Serum, plasma, bone marrow aspirate and bone marrow core biopsy tissue will be 
collected per Appendix H.  Subjects will also have the option to provide samples for 
exploratory research.  Subjects may still participate in the main study even if they decide 
not to participate in the optional exploratory research.  Samples may be utilized to 
evaluate known and/or novel markers (nucleic acids, peptides/proteins and/or metabolites) 
of disease status, related conditions or to evaluate the association with pharmacokinetics, 
safety or efficacy.  All samples should be prepared, labeled, and shipped as outlined in the
study-specific laboratory manual.  The biomarker rationale is discussed in the Biomarker 
Research Variables Section (Section 5.3.6).
AbbVie (or people or companies working with AbbVie) will store the biomarker and 
exploratory research samples in a secure storage space with adequate measures to protect 
confidentiality.  The samples will be retained while research on venetoclax (or drugs of 
this class) or this disease and related conditions continues, but for no longer than 20 years 
 

Venetoclax

after study completion, or per local requirements.  The procedure for obtaining and 
documenting informed consent is discussed in Section 9.3.
COVID-19 Pandemic-Related Acceptable Protocol Modification: 
Biomarker and exploratory research samples may only be collected at the study site and 
are not to be collected if travel restrictions or other changes in local regulations in light of 
the COVID-19 pandemic prevent the subject from visiting the study site at a sample 
collection time point.

Pre-Treatment Bone Marrow Core (BMC) Biopsy Tissue Collection for 
Immunohistochemistry (IHC)
One of the following forms of pre-therapy tumor tissue (newly collected tissue or archived 
tissue) should be collected at Screening:
●
Fresh tumor tissue:  It is strongly encouraged that BMC biopsies be collected 
for all subjects to enable biomarker assessments as outlined in the study 
objectives.  BMC biopsies should be performed during screening, unless not 
recommended per Institution guidelines.  Tissue should be fixed in formalin, 
decalcified, and embedded in paraffin according to institutional procedures.  
While sending Formalin-Fixed, Paraffin-Embedded (FFPE) blocks is preferred, 
slides prepared and stored by the local pathology laboratory are acceptable and 
should be prepared as described in the study-specific laboratory manual.  In 
addition, a pathology report, with all the subject identifying information 
redacted, should be submitted along with the tissue sample.
●
Archived BMC biopsy tissue:  The most recent archived diagnostic specimen 
is acceptable, provided the sample is representative of the subject's current 
disease state at the time of study entry.  While sending FFPE blocks is 
preferred, slides prepared by the local pathology laboratory are acceptable and 
should be prepared and stored as described in the study-specific laboratory 
manual.  In addition, a pathology report, with all the subject identifying 
information redacted, should be submitted along with the tissue sample.
Bone Marrow Aspirate Collection
A sufficient bone marrow aspirate MUST be collected for clinical assessment as well as 
for biomarker analyses.  Priority of the aspirate sample split is as follows:
1.

Efficacy Variables
The primary endpoint is PFS based on IMWG criteria for multiple myeloma 
(Appendix J).13,14
 

Venetoclax
M14-031 Protocol Amendment 8

81
Secondary efficacy endpoints are as follows:  VGPR or better response rate; PROs:  
Worst Pain (BPI-SF), Physical Functioning (EORTC QLQ-C30); OS; PFS in subjects 
with high BCL-2 expression; DOR; TTP; ORR; MRD negativity rate; PROs GHS/QoL 
(EORTC QLQ-C30), and Fatigue (PROMIS Cancer Fatigue SF).
Tertiary efficacy endpoints are CBR, DCR, TTR, TNT, and PROs based on the remaining 
subscales of BPI-SF, EORTC QLQ-C30, EORTC QLQ-M20, and EQ-5D-5L.
Efficacy endpoints and analyses of efficacy are described in Section 8.1.3 and 
Section 8.1.5.
5.3.4

monitoring, vital signs, physical examination, 12-lead ECG and laboratory assessments.
5.3.5
Pharmacokinetic Variables
Values for the PK parameters of venetoclax, including the apparent clearance (CL/F), may 
be determined using a population PK approach.  Additional parameters may be calculated 
if useful in the interpretation of the data.
5.3.6
Biomarker and Exploratory Research Variables
Biospecimens (blood, serum, plasma, bone marrow aspirate and bone marrow core biopsy 
tissue) will be collected to conduct biomarker and exploratory analyses.  The types of 
biomarkers to be analyzed may include, but are not limited to, nucleic acids, proteins, 
lipids or metabolites.  The samples may be analyzed as part of a multi-study assessment of 
factors influencing the subjects' response to the study treatment (or drugs of the same or 
similar class) or the development and progression of the subjects' disease or related 
conditions.  The information learned from analyzing these samples may be used to 
investigate factors influencing response to the study treatment, scientific questions related 
to multiple myeloma, and/or in the development of new therapies and diagnostic tests, or 
technologies.  The results from these analyses may not be included with the study report.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
82
Biospecimens (serum, plasma, bone marrow aspirate and bone marrow core biopsy tissue) 
will be collected to support biomarker objectives of the study.  These include assessment 
of BCL-2 expression at baseline as a predictive biomarker of response to the combination 
of venetoclax with bortezomib and dexamethasone.  BCL-2 protein expression will be 
determined by IHC analysis in bone marrow core biopsy samples.  A pre-defined 
threshold for BCL-2 expression status (high/low) will be utilized to compare median PFS 
between treatment arms in subjects with High BCL-2 expression as a secondary endpoint 
in the study.  Furthermore, BCL-XL and MCL-1 protein expression will be assessed as 
exploratory markers.  Additionally, BCL-2, BCL-XL and MCL-1 gene expression may be 
evaluated in CD138-enriched bone marrow aspirate samples by sequencing-based 
methodologies, including qPCR.  The ratio of target expression (BCL-2) to resistance 
factors (MCL-1/BCL-XL) was found to associate with tumor responses to single agent 
venetoclax treatment in pre-clinical studies of multiple myeloma.9  Clinically, higher 
BCL-2 mRNA expression levels were associated with improved overall response rate in 
the Study M12-901.
Additional biomarker objectives include the assessment of FISH markers that are known 
to be prognostic in MM.  These include, but not limited to, t(11;14), t(4;14), t(14;16), 
del17p, and 5+, 9+, or 15+.  Patient multiple myeloma tumor cells that possess the 
t(11;14) translocation were found to associate with increased sensitivity to venetoclax in 
preclinical studies of MM.9  t(11;14) positive samples also demonstrated a high median 
BCL-2/MCL-1 mRNA ratio.9  FISH analysis will be performed on CD138-enriched 
samples from bone marrow aspirates.
MRD negativity is an emerging component of response assessment in multiple myeloma 
patients who have achieved complete responses.  Recent reports have demonstrated the 
potential prognostic value of MRD detection in multiple myeloma with sensitive assays 
that define immunophenotypic disease specific (via flow cytometry) and/or molecular 
(Allelle Specific Oligonucleotide – Polymerase Chain Reaction [ASO-PCR] or Next 
Generation Sequencing [NGS]) abnormalities.29-32  MRD negativity in bone marrow 
aspirates will be defined at 10–5 threshold as assessed by NGS in subjects at the time of 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
83
suspected CR/sCR, and at 6 and 12 months post-confirmation of CR/sCR for subjects who 
maintained this response.  Exploratory analysis of MRD negativity at 10–4 and 10–6
thresholds may additionally be performed.
Additional exploratory evaluations may include biomarkers related to pathway(s) targeted 
by the study treatment, those believed to be related to the disease or to drug response 
evaluation or association with genetic factors.  Plasma and serum samples may be 
analyzed for mutational status of circulating tumor DNA and measurement of relevant 
cytokine, chemokine, matrix metalloproteinases and markers of bone turnover 
(formation/resorption).  The analyses of tumor tissue/cells may include but are not limited 
to IHC and qPCR-based assays for BCL-2 family members and other nucleic acids or 
proteins known to regulate the expression of these molecules.  Gene sequencing- and 
hybridization-based techniques may also be used on any of the above specimens for 
exploratory biomarker research.
Pharmacogenetic samples may also be analyzed for genetic factors contributing to the 
disease or to the subject's response to venetoclax, or other study treatment in terms of 
pharmacokinetics, efficacy, tolerability, and safety.  Pharmacogenetic research on samples 
from Japan will be restricted to the subject's response to treatment.  Such genetic factors 
may include sequencing and epigenetic testing on genes associated with drug 
metabolizing enzymes, drug transport proteins, genes within the target pathway, genes 
believed to be related to the disease or to drug response.  Some genes currently 
insufficiently characterized or unknown may be understood to be important at the time of 
analysis.  The results are exploratory in nature, and may not be included in the clinical 
study report.

Disease Assessments and IMWG Criteria for Response and 
Progression
5.3.7.1
Disease Assessments
Analysis of serum protein electrophoresis (SPEP), serum protein immunofixation, serum 
quantitative immunoglobulins (sQI), serum free light chains (sFLC), urine protein 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
84
electrophoresis (UPEP), urine protein immunofixation, corrected serum calcium, 
plasmacytoma evaluation (if applicable), skeletal survey, and bone marrow aspirate and 
biopsy, will be utilized for disease assessment.  Subjects will be evaluated using the 
IMWG13,14 criteria for disease response and progression.45
Laboratory Tests for Multiple Myeloma:
All serum and urine laboratory tests for multiple myeloma must be sent to a certified 
central laboratory.  Corrected serum calcium will be based off the serum calcium and 
albumin levels obtained from the local laboratory.
Serum protein immunofixation, SPEP, sQI, sFLC, urine protein immunofixation, and 
UPEP may be performed up to 1 week prior to the scheduled visit day.
Serum Protein Electrophoresis (SPEP), Serum Protein Immunofixation, Serum 
Quantitative Immunoglobulins (sQI)
Blood samples for SPEP, serum protein immunofixation, and sQI testing will be collected 
per Table 4 and Appendix D, Appendix E, Appendix F, and Appendix G.
SPEP and serum immunofixation will be collected for all subjects at baseline and 
throughout the study until PD or withdrawal of consent, regardless of SPEP being 
measurable or M-protein presence at baseline.
Once the number of OS events required for the final OS analysis is reached, SPEP and 
serum immunofixation will continue to be collected only from the subjects on treatment.
At the time that subjects are unblinded, subjects in Arm 1 (Venetoclax + Bd) or Arm 2 
(Placebo + Bd) may continue on study treatment per PI decision, unless PD is presented, 
provided that subjects are benefiting from treatment.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
85
Serum Free Light Chains (sFLC)
Blood samples for sFLC testing will be collected for all subjects per Table 4 and 
Appendix D, Appendix E, Appendix F, and Appendix G. 
Subjects with measurable disease in either SPEP and/or UPEP will be assessed for clinical 
response only based on these two tests and not by the sFLC assay.  sFLC response criteria 
are only applicable to subjects without measurable disease in the serum or urine and to 
fulfill the requirements of sCR per IMWG criteria.
Corrected Serum Calcium
Blood samples for corrected serum calcium testing will be collected for all subjects per 
Table 4 and Appendix D, Appendix E, Appendix F, and Appendix G. 
The determination of corrected serum calcium levels is required to perform disease 
assessment.  If corrected serum calcium is used as a criterion for disease progression, it 
must be confirmed by a second value.  The correction will be done according to the 
following formula:
Corrected Serum Calcium [mg/dL] = Measured serum calcium [mg/dL] + 0.8 × (4 –
serum albumin [g/dL]).
Urine Protein Immunofixation and Urine Protein Electrophoresis (UPEP), 24-Hour 
Urine
Twenty-four-hour urine samples for urine protein immunofixation and UPEP for 
M-protein testing will be collected for all subjects at each Cycle Day 1 visit per Table 4
and Appendix D, Appendix E, Appendix F, and Appendix G.
Importantly, assessment of UPEP M-protein and urine immunofixation at the time of 
possible VGPR or CR/sCR is mandatory, even in subjects without measurable values at 
baseline.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
86
Subjects with measurable disease at baseline by SPEP and UPEP must be followed by 
both SPEP and UPEP assessment of M-protein for response assessment.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
If travel restrictions or other changes in local regulations in light of the COVID-19 
pandemic prevent the subject from visiting the study site for the collection and shipping of 
IMWG laboratory assessments to the central laboratory, a local laboratory, hospital, or 
other facility may be used to manage subject disease assessment of IMWG (Serum 
M-Protein, Urine M-Protein, Serum Free Light Chains).  Local lab results should be 
obtained along with reference ranges and kept within the subject's source documentation.  
Local lab results should be reviewed by the investigator as soon as possible and prior to 
study drug dispensation.
Skeletal Survey
Skeletal survey using conventional radiography (X-Ray) will be done at screening.  Use 
of conventional or low dose CT scan or magnetic resonance imaging (MRI) bone survey 
is acceptable.  If imaging is done on treatment for assessment of progression, the site must 
use the same modality of imaging as used in screening.  Historical skeletal survey results 
obtained within 30 days prior to randomization may be used for Screening provided that 
the images meet the requirements in the Image Acquisition Guidelines.  A skeletal survey 
will be comprised of the following:
●
Lateral radiograph of skull
●
Antero-posterior and lateral views of the spine
●
Antero-posterior views of pelvis, ribs, femora, tibiae, fibulae, humeri, ulnae and 
radii
Skeletal surveys should be completed per Table 4 and Appendix D, Appendix E, 
Appendix F and Appendix G.  After the screening procedure, skeletal survey should be 
done while on study only if clinically indicated.  The number and location of skeletal and 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
87
lytic lesions should be recorded on the eCRF.  While the subject is on treatment, survey 
(if done) should record any changes to the number of or size of lytic lesions, as well as the 
number and location of any new skeletal or lytic lesions.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
In the event the skeletal survey cannot be performed at the study site due to study 
modifications related to the COVID-19 pandemic, the skeletal survey may be completed 
at other centers providing the modality/technique is equivalent.
Plasmacytoma Evaluation
Plasmacytoma evaluation should be assessed for all subjects with a history of 
plasmacytomas or if clinically indicated at Screening, via physical examination or 
imaging, and should be completed per Table 4, and Appendix D, Appendix E, 
Appendix F, and Appendix G.  Positron emission tomography (PET) scan or ultrasound 
tests are not acceptable to document the size of extramedullary plasmacytomas.
CT, PETCT (CT component) or MRI (same method should be used throughout study if 
possible) should be performed in all subjects if clinically indicated at baseline to assess 
for the presence of extramedullary plasmacytoma.  To minimize unnecessary radiation in 
myeloma subjects where progression is primarily based on serum and urine M-protein, 
on-study assessments should only be performed if clinically indicated (e.g., pain, concern 
for disease progression), whether or not present at baseline, and to confirm MR or better 
responses if plasmacytoma is present at baseline.
In addition to be reviewed by the Investigator and/or qualified medical site staff, imaging 
scans should be sent within 5 business days of imaging acquisition to an independent 
central imaging vendor.  The central imaging vendor will provide instructions regarding 
the preparation and shipment/upload of the images.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
88
A sum of the products of the longest diameters and longest perpendicular diameter for all 
measurable lesions will be calculated at baseline.  This sum will be used as the reference 
for on-study assessments by which to characterize the objective tumor response.
All tumor measurements must be made in millimeters.  All documented measurable 
lesions are to be followed throughout the trial.  All assessments to be used for tumor 
response evaluation, including the baseline assessment, must be performed using the same 
method for repeat assessment.  CT, PET/CT or MRI scanning are the preferable methods 
of assessment.  Conventional CT, PET/CT or MRI should be performed with contiguous 
cuts of 10 mm or less or with cuts of 5 (or 10) mm if spiral CT scanning is used.  
Imaging-based evaluation is preferred to evaluation by clinical examination.  Evaluation 
by chest x-ray is less preferable than CT, PET/CT or MRI, and should only be used for 
well-defined lesions surrounded by aerated lung.  Clinical examination is only acceptable 
when lesions are superficial, such as a skin nodule or palpable lymph node.  Skin lesions 
must be documented by a photograph with a ruler.
Duplicate copies of all imaging studies used for tumor response evaluation will be made 
available for review by AbbVie or designee upon request.
Measurable disease are lesions that can be accurately measured in 2 dimensions and both 
diameters must be ≥ 20 mm when evaluated by standard CT scanning or ≥ 10 mm when 
evaluated by spiral CT scanning.  Non-measurable disease are all other lesions (or sites of 
disease), including those that are too small (i.e., do not meet above criteria), occur within 
a previously irradiated area (unless they are documented as new lesions since the 
completion of radiation therapy), bone lesions, leptomeningeal disease, ascites, pleural or 
pericardial effusion (exception for effusions documented by cytology as not malignant or 
present at baseline without progression), lymphangitis cutis/pulmonis, abdominal masses 
that are not pathologically/cytologically confirmed and followed by imaging techniques, 
and cystic lesions.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
89
With the completion of the PFS analysis, imaging scans are no longer required to be sent 
to an independent central imaging vendor and will be reviewed only by the Investigator 
and/or qualified medical site staff.  
COVID-19 Pandemic-Related Acceptable Protocol Modification:
In the event the imaging for plasmacytoma assessment cannot be performed at the study 
site due to study modifications related to the COVID-19 pandemic, the imaging may be 
completed at other centers providing the modality/technique is equivalent.
Bone Marrow Aspirate and Biopsy
Bone marrow aspirate and biopsy should be completed per Table 4 and Appendix D, 
Appendix E, Appendix F, and Appendix G.  Bone marrow aspirates and biopsies 
performed as standard of care throughout the study should also be captured on an eCRF.
A sufficient bone marrow aspirate or biopsy must be collected for clinical assessment 
(pathology) performed by local laboratory as well as for shipment of a portion to AbbVie 
(or designee) for the biomarker analyses (including BCL-2 expression, qPCR/MRD 
assessment, and FISH subtyping) as described in Section 5.3.1.3 per Appendix H.
Assessment of bone marrow for percentage plasma cells performed locally is required 
within 21 days prior to randomization for baseline assessment and while on study to 
confirm sCR/CR (i.e., subjects who become immunofixation negative) or, at time of 
suspected disease progression if clinically indicated.
Bone marrow plasma cell clonality must also be evaluated locally at the time of CR (< 5% 
plasma cells) to assess for sCR, if applicable.  Flow cytometry is preferred over IHC for 
assessment of plasma cell clonality.  Flow cytometry will be performed to assess for sCR 
locally per institution standard practice.  If local flow cytometry to assess plasma cell 
clonality is not available at the time of CR, a core biopsy and/or clot section should be 
evaluated by IHC staining for kappa (κ) or lambda (λ) or light chain restriction.  To 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20

confirm a suspected CR, a second confirmation bone marrow analysis for CR is not 
needed.
A bone marrow aspirate collection is mandatory.  Bone marrow biopsy should be also 
collected, unless not recommended per Institutional guidelines.  However, a bone marrow 
biopsy is mandatory in the circumstance that an aspirate sample is not available (e.g., due 
to a dry tap).
COVID-19 Pandemic-Related Acceptable Protocol Modification:
Bone marrow samples may only be collected at the study site and are not to be collected if 
travel restrictions or other changes in local regulations in light of the COVID-19 
pandemic prevent the subject from visiting the study site at a sample collection time point.

Subjects will be assessed for response using the IMWG response criteria 
(Appendix J).13,14  Disease status categories include sCR, CR, VGPR, PR, MR, defined 
per EBMT criteria, stable disease (SD) and PD.
All response categories (i.e., sCR, CR, VGPR, PR, MR and PD) require two consecutive 
assessments completed by the central lab to be considered confirmed.  All response 
categories sCR, CR, VGPR, PR, MR and SD also require no known evidence of 
progressive or new bone lesions if radiographic studies were performed.  Radiographic 
studies are not required to satisfy these response requirements.
Subjects with measurable disease in both serum (SPEP) and urine (UPEP) at study entry 
are required to meet response criteria in both UPEP and SPEP to qualify for a MR or 
better.  On the other hand, criteria for PD only need to be met and confirmed in 
one parameter.
At the time that subjects are unblinded, subjects in Arm 1 (Venetoclax + Bd) or Arm 2 
(Placebo + Bd) may continue on study treatment per PI decision, unless PD is presented, 
provided that subjects are benefiting from treatment.
Stringent Complete Response (sCR)
sCR requires that all of the following criteria be met:
●
Negative immunofixation on serum and urine, regardless of whether disease at 
baseline was measurable on serum, urine, both, or neither, AND
●
Disappearance of any soft tissue plasmacytomas, AND
●
< 5% plasma cells in bone marrow (confirmation with repeat bone marrow 
aspirate or biopsy not needed), AND
●
Normal FLC ratio of 0.26 to 1.65 or per laboratory reference range, AND
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
93
●
Absence of clonal plasma cells in bone marrow by immunohistochemistry or 
immunofluorescence or 2 to 4 color flow cytometry (confirmation with repeat 
bone marrow biopsy not needed).
Presence or absence of clonal plasma cells is based upon the k/λ ratio.  An abnormal k/λ 
ratio by immunohistochemistry, and/or flow cytometry and/or immunofluorescence 
requires a minimum of 100 plasma cells for analysis.  An abnormal ratio reflecting 
presence of an abnormal clone is k/λ of ≥ 4:1 or ≤ 1:2.
Serum and urine M-protein testing is required to fulfill requirements of sCR regardless of 
whether disease at baseline was measurable on serum, urine, both, or neither.
Complete Response (CR)
CR requires that all of the following criteria be met:
●
Negative immunofixation on serum and urine, regardless of whether disease at 
baseline was measurable on serum, urine, both, or neither, AND
●
Disappearance of any soft tissue plasmacytomas, AND
●
< 5% plasma cells in bone marrow (confirmation with repeat bone marrow 
aspirate or biopsy not needed), AND
●
For subjects in whom the only measurable disease is by serum FLC levels, a 
normal FLC ratio of 0.26 to 1.65 (or per laboratory reference range) is required, 
in addition to all the CR criteria listed above.
It is not essential to perform a trephine biopsy, but if a biopsy is performed this must also 
contain < 5% plasma cells.
Serum and urine M-protein testing is required to fulfill requirements of CR regardless of 
whether disease at baseline was measurable on serum, urine, both, or neither.
Very Good Partial Response (VGPR)
VGPR is defined as follows:
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
94
●
Serum and urine M-protein detectable by immunofixation but not on 
electrophoresis OR
●
90% or greater reduction in serum M-protein plus urine M-protein level 
< 100 mg/24-hour
For subjects in whom the only measurable disease is by serum FLC levels, VGPR is 
defined as follows:
●
90% or greater decrease in the difference between involved and uninvolved 
FLC levels
Serum and urine M-protein testing is required to fulfill requirements of VGPR regardless 
of whether disease at baseline was measurable on serum, urine, both, or neither.
Partial Response (PR)
PR is defined as follows:
●
≥ 50% reduction of serum M-protein AND
●
Reduction in 24-hour urinary M-protein by ≥ 90% or to < 200 mg/24-hour, 
AND
●
≥ 50% reduction in size of soft tissue plasmacytomas, if present at baseline
If serum and urine M-protein levels are unmeasurable, a ≥ 50% decrease in the difference 
between involved and uninvolved FLC levels is required in place of the M-protein 
criteria.
Minimal Response (MR)
Subjects who have reduction in M-protein or plasmacytoma but do not meet the criteria 
for PR are classified as MR if they meet all the following definition:
●
25% – 49% reduction of serum M-protein AND
●
50% – 89% reduction in 24-hour urinary M-protein AND
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
95
●
25% – 49% reduction in size of soft tissue plasmacytomas, if present at 
baseline AND
●
If a skeletal survey is done, no increase in size or number of lytic bone lesions 
(development of compression fracture does not exclude response)
Stable Disease (SD)
SD is defined as not meeting the criteria for sCR, CR, VGPR, PR, MR, or PD.
Subjects with confirmed sCR, CR, VGPR, and PR will be considered to have achieved an 
objective response.  Subjects with objective response and those with MR will be 
considered to have achieved clinical benefit.  Additionally, subjects with clinical benefit 
and those with stable disease lasting at least 8 weeks will be considered to have achieved 
disease control.
Progressive Disease (PD)
PD is determined using the IMWG criteria (Appendix J),13,14 and is defined as any one or 
more of the following:
●
Increase of ≥ 25%* from lowest response level in any of the following:
○
Serum M-protein with an absolute increase of ≥ 0.5 g/dL
○
Serum M-protein increases of ≥ 1 g/dL are sufficient to define relapse if 
starting M-protein is ≥5 g/dL
○
Urine M-protein with an absolute increase of ≥ 200 mg/24-hour
○
For subjects without measurable serum and urine M-protein levels, the 
difference between involved and uninvolved FLC levels with an absolute 
increase of > 10 mg/dL
●
Definite development of new bone lesions or soft tissue plasmacytomas
●
Definite increase in the size of bone lesions or soft tissue plasmacytomas
○
A definite increase in size of bone lesions and/or plasmacytomas is defined 
as ≥ 50% increase from nadir in the sum of the product of the cross-
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
96
diameters (SPD) of > 1 lesion, or ≥ 50% increase in the longest diameter of 
a previous lesion > 1 cm in short axis.45
●
Development of hypercalcemia (corrected serum calcium > 11.5 mg/dL) that 
can be attributed solely to the plasma cell proliferative disorder
*
Note:  The "25% increase" refers to M-protein and, FLC results and does 
not refer to bone lesions, soft tissue plasmacytomas, or hypercalcemia.  
The "lowest response value" does not need to be a confirmed value.
Two consecutive assessments, made at any time before the start of new therapy, are 
required for confirmation of PD per IMWG criteria.  The second assessment may be taken 
immediately if PD is suspected.  If PD is suspected by rising serum or urine M-protein (or 
FLC in subjects without measurable disease), two consecutive assessments from central 
laboratory readings should be obtained.
If PD is suspected by clinical symptoms, a plasmacytoma evaluation and/or skeletal 
survey should be obtained, as clinically indicated, and compared with baseline 
assessments to determine whether a new bone lesion or plasmacytoma has developed or 
an existing lesion or plasmacytoma has worsened.  SPEP and UPEP are also required.
If PD is suspected based on hypercalcemia attributed solely to the plasma cell 
proliferative disorder, the laboratory values for corrected serum calcium should be greater 
than 11.5 mg/dL (2.875 millimole [mmol]/L) and a confirmatory reading should be 
obtained.
The following assessments are not sufficient to determine progressive disease:
●
Rising sFLC or quantitative immunoglobulins.  In this situation, SPEP and 
UPEP should be performed and progressive disease determination should be 
made based on central lab readings.
○
Serum FLC can be used to determine PD according to the IMWG criteria 
only for subjects without measurable serum and urine M protein.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
97
●
Clinical relapse based on indicators that are not part of the IMWG criteria for 
PD (e.g., decrease in hemoglobin, increase in serum creatinine, hyperviscosity), 
and relapse from CR categories should not be considered progressive disease.
●
General worsening of the subject's condition.  If a subject's condition has 
deteriorated to a point that remaining on protocol therapy is not an option, 
every effort should be made to document progressive disease by at least one of 
the following assessments prior to the initiation of new therapy:  SPEP, UPEP, 
bone marrow biopsy, plasmacytoma evaluation, skeletal survey, or 
hypercalcemia (attributed solely to myeloma).
Due to delays in receiving response information from the central laboratory and also the 
possible lag time in the manifestation of clinical efficacy, Investigators are requested not 
to discontinue subjects from treatment for presumed lack of response after only 1 cycle of 
study treatment.
Clinical Relapse
Clinical relapse is defined per IMWG criteria (Appendix J)13,14 as requiring one or more 
of the following direct indicators of increasing disease and/or end organ dysfunction 
(CRAB features [increased calcium level, kidney (renal) failure, anemia, and destructive 
bone lesions]) that are considered related to the underlying plasma cell proliferative 
disorder:
●
Development of new soft tissue plasmacytomas or bone lesions on skeletal 
survey, MRI or other imaging
●
Definite increase in size of existing plasmacytomas or bone lesions.  A definite 
increase is defined as a 50% (and at least 1 cm) increase as measured serially 
by the sum of the products of the cross-diameters of the measurable lesion
●
Hypercalcemia > 11.5 mg/dL (> 2.875 mM/L)
●
Decrease in hemoglobin of > 2 g/dL (> 1.25 mM) or to < 10 g/dL
●
Rise in serum creatinine by ≥ 2 mg/dL (≥ 177 mM/L)
●
Hyperviscosity

5.3.7.3
Evaluation of Disease
IMWG assessments will be reviewed by the Investigator per the IMWG criteria 
(Appendix J)13,14 outlined in Section 5.3.7.2.  If the Investigator confirms the subject 
meets the criteria for progressive disease, the subject will be deemed as having met an 
event of disease progression.  For the purposes of this study, the date of progression will 
be the date on which the IMWG assessments were obtained.
IMWG assessments will be performed by the central laboratory.  Investigators may 
choose to submit additional samples to their local laboratory for testing.  All local lab 
results must be entered into the eCRF.
Disease assessment for each post-baseline IMWG assessment will be performed by a team 
of independent multiple myeloma experts (IRC).  The IRC will review subject data in a 
blinded fashion to provide the overall response assessment and associated response 
assessment date.  The IRC will only review clinical data and imaging relevant for the 
disease assessment.  Interpretations from the IRC will not be sent to the site.
A charter will outline the review process for IRC determination of overall response.
With the completion of the PFS analysis, post-baseline IMWG assessments are no longer 
required to be sent to the IRC and will be reviewed only by the Investigator and/or 
qualified medical site staff.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
If travel restrictions or other changes in local regulations in light of the COVID-19 
pandemic prevent the subject from visiting the study site for the collection and shipping of 
IMWG laboratory assessments to the central laboratory, a local laboratory, hospital, or 
other facility may be used to manage subject disease assessment of IMWG (Serum 
M-Protein, Urine M-Protein, Serum Free Light Chains).  Local lab results should be 
obtained along with reference ranges and kept within the subject's source documentation.  
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
99
Local lab results should be reviewed by the investigator as soon as possible and prior to 
study drug dispensation.
5.4
Removal of Subjects from Therapy or Assessment
5.4.1
Discontinuation of Individual Subjects from Treatment
Each subject has the right to withdraw from the study at any time.  In addition, the 
Investigator may discontinue a subject from treatment at any time for any reason if the 
Investigator considers it necessary, including the occurrence of an adverse event or 
noncompliance with the protocol.  Each subject will be withdrawn from the treatment if 
any of the following occur:
●
Disease progression confirmed through IMWG assessments;
●
Subjects who are just on dexamethasone monotherapy;
●
The subject experiences toxicities related to study treatment that requires more 
than a 3-week dose interruption of the study treatment;
●
The subject receives an anti-myeloma treatment not specified in the protocol 
and prior to documented disease progression; 
●
The subject becomes pregnant or begins breastfeeding;
●
Unacceptable toxicity;
●
Noncompliance with the protocol.
If a subject is discontinued from treatment or the study with an ongoing adverse event, the 
Investigator will attempt to provide follow-up until a satisfactory clinical resolution of the 
adverse event is achieved.
At the end of the subject's treatment, a TCV will be completed.
A Safety Follow-Up Visit should be performed for all subjects approximately 30 days 
following last dose of treatment.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
100
A separate Safety Follow-Up Visit does not need to be performed for subjects who had a 
Treatment Completion Visit conducted ≥ 30 days after discontinuation of the study 
treatment and did not require additional follow-up visits for disease or safety assessment.  
If the subject refuses or is unable to attend the Safety Follow-Up Visit, this should be 
noted in the subject's source documentation.
In the event that a positive result is obtained on a pregnancy test for a subject or a subject 
reports becoming pregnant during the study, the administration of the study treatment 
must be discontinued immediately.  The Investigator must report a pregnancy within 
1 working day of the site being aware to one of the AbbVie representatives listed in 
Section 6.1.5.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
The investigator should contact the AbbVie TA MD or designee before discontinuing a 
subject from the study for reasons other than those identified above to ensure all 
acceptable mitigation steps have been explored.
All efforts should be made to obtain safety and disease response information at the 
Treatment Completion visit prior to the subject initiating another therapy.  If travel 
restrictions or other changes in local regulations in light of the COVID-19 pandemic 
prevent the subject from having blood drawn for laboratory testing at the study site at the 
TCV and/or Safety Follow-Up Visit, if possible, arrange for subjects to have laboratory 
work done at a local laboratory, hospital, or other facility.  Local lab results should be 
obtained along with reference ranges and kept within the subject's source documentation.  
Local lab results should be reviewed by the investigator as soon as possible.
Non-Treatment Emergent Death Collection  
Refer to Section 5.3.1.1.2 for more information on Non-Treatment Emergent Death 
Collection.  
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
101
Importantly, if a subject discontinues treatment for a reason other than PD, the 
subject will still be considered "on study" until the number of OS events required 
for the final OS analysis is reached, and followed for diseases assessments until the 
events of PD, death or withdrawal of consent.  Once the number of OS events 
required for the final OS analysis is reached, if a subject discontinues treatment for 
any reason, the subject will be discontinued from the study.
5.4.2
Withdrawal from Study Visits
A subject may decide to discontinue participation in study visits and procedures.  If 
subject withdraws from study visits, the subject must discontinue treatment, and the 
reason for withdrawal must be documented in the subject's medical record and signed by 
the Investigator.  Subject will be followed for OS.
If withdrawal from study visits occurs at the time the number of OS events required for 
the final OS analysis is reached, subject will be discontinued from treatment and from the 
study.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
During the COVID 19 pandemic, it has been necessary to employ mitigation strategies to 
enable the investigator to ensure subject safety and continuity of care.  Additional 
guidance regarding the location of COVID-19 pandemic-related acceptable protocol 
modifications can be found in Section 5.3.1.1.
The investigator should contact the AbbVie TA MD or designee before discontinuing a 
subject from the study for reasons other than those identified in Section 5.4.1 to ensure all 
acceptable mitigation steps have been explored.
5.4.3
Withdrawal from Follow-Up
Subject must request to be withdrawn specifically from survival follow-up; this request 
must be documented in the subject's medical record and signed by the Investigator.  If the 
subject withdraws from survival follow-up, the site staff may use a public information 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
102
source (such as county records) to obtain information about survival status only, as 
appropriate per local regulations.
Once the number of OS events required for the final OS analysis is reached, subjects will 
no longer be followed for progression or survival, and survival follow up withdrawal will 
no longer apply.
5.4.4
Discontinuation of Entire Study
AbbVie may terminate this study prematurely, either in its entirety or at any study site, for 
reasonable cause provided that written notice is submitted in advance of the intended 
termination.  An Investigator may also terminate the study at his/her site for reasonable 
cause, after providing written notice to AbbVie in advance of the intended termination.  
Advance notice is not required by either party if the study is stopped due to safety 
concerns.  If AbbVie terminates the study for safety reasons, AbbVie will immediately 
notify the Investigators by telephone and subsequently provide written instructions for 
study termination.
If, in the judgment of the Investigators and AbbVie, the continued exposure to the study 
treatment represents a significant risk to subjects, the study will be stopped.  The 
following procedures for discontinuation will be followed:
●
If the sponsor has decided to prematurely discontinue the study, the sponsor 
will promptly notify the Investigators in writing as well as regulatory 
authorities of the decision and give detailed reasons for the discontinuation.
●
The Investigators must promptly notify the IEC/IRBs and give detailed reasons 
for the discontinuation.
●
The Investigators must promptly notify the enrolled subjects of the premature 
discontinuation and administer appropriate treatments such as replacement of 
the study treatment, if applicable, by other appropriate regimens.

5.5
Treatments
5.5.1
Treatments Administered
Subjects will take daily venetoclax/placebo 800 mg orally in combination with Bd.  
Venetoclax/placebo should always be given before other agents administered on the same 
day, if applicable.  Subjects will self-administer venetoclax/placebo by mouth QD.  Each 
dose of venetoclax/placebo should be taken all at one time with approximately 240 mL of 
water within 30 minutes after completion of breakfast or the subject's first meal of the 
day.  Tablets must be swallowed whole and must not be broken, chewed, or crushed.  On 
days that pre-dose PK sampling is required, dosing will occur at the clinic to facilitate PK 
sampling.
In cases of vomiting, the subject should not take any additional dose that day and next 
dose should be taken at usual time the next day.  In cases where a dose is missed or 
forgotten, the subject should take the dose as soon as possible, ensuring the dose is taken 
within 8 hours of the missed dose with food.  Otherwise, the dose should not be taken.
Placebo tablet administration will no longer be required for subjects in Arm 2 (Placebo + 
Bd) who remain in the study at the time subjects are unblinded.
Bortezomib (1.3 mg/m2 subcutaneous injection [preferred] or IV) will be given following 
administration of venetoclax/placebo in Cycles 1 – 8 on Days 1, 4, 8 and 11, and for 
Cycles 9 and beyond, on Days 1, 8, 15 and 22 and should be administered per the 
prescribing information.33  Dose capping and dose rounding of bortezomib is permitted 
per institutional guidelines.  The route of administration should not change during the 
study.
Bortezomib dosing frequency may be reduced or discontinued per investigator's decision 
and institutional guidelines once subjects are unblinded.
Dexamethasone (20 mg) will be given orally in Cycles 1 – 8 on Days 1, 2, 4, 5, 8, 9, 11 
and 12, and in Cycles 9 and beyond, Days 1, 2, 8, 9, 15, 16, 22, and 23.  Dexamethasone 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
104
should be administered per the prescribing information.  Dexamethasone should be 
administered the day of bortezomib dosing and the following day, given the protocol 
defined dosing window (bortezomib dosing window is ± 1 day) is maintained.  If 
bortezomib is interrupted or a dose is skipped, dexamethasone should still be administered 
as scheduled per protocol (unless dexamethasone is interrupted due to toxicity).  When 
bortezomib is discontinued and venetoclax/placebo and/or dexamethasone dosing 
continues, adverse events and concomitant medications need only be evaluated on Day 1 
of each cycle visit.
Dexamethasone dosing (frequency and/or dose) may be reduced or discontinued per 
investigator's decision and institutional guidelines once subjects are unblinded.
When unblinding occurs, if subjects from Arm 1 (Venetoclax + Bd) and Arm 2 (Placebo + 
Bd) are on dexamethasone monotherapy, they must be discontinued from the study 
treatment and from the study once the Safety Follow-Up Visit is completed.
TLS prophylaxis should be considered as discussed in Section 6.1.7.2.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
If a subject is unable to come to the study site to pick up their study drug due to 
COVID-19, a direct-to-patient (DTP) study drug shipment can be made, for 
venetoclax/placebo and dexamethasone only, from the study site to the subject, if allowed 
by local regulations.  DTP shipments of venetoclax/placebo or dexamethasone may also 
include additional non-drug study supplies (e.g., patient diaries, 24-hour urine collection 
containers, etc.).  AbbVie will submit any required notifications to the regulatory 
authority as applicable.  Prior to DTP shipping, the study site must confirm it is still safe 
for the subject to continue treatment via onsite (preferred), phone or video conference 
visit, or local assessments as permitted through COVID-19 Pandemic-Related Acceptable 
Protocol Modifications.  These assessments should be documented in the subject's source 
documents accordingly.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
105
Study drug may be shipped from the study site directly to the study subject's home if all 
the following criteria are met:
●
Direct-to-patient (DTP) shipment of study drug is allowed by local regulations 
and the relevant ethics committee
●
Study drug can be administered by the subject at home
●
Subject agrees to have the study drug shipped directly to his/her home
●
Assessment of the following procedures prior to dispensing venetoclax/placebo 
to subjects:  hematology, chemistry, urine pregnancy testing (women of 
childbearing potential), coagulation panel (when applicable), IMWG disease 
assessment (central lab collection preferred, local laboratory acceptable if not 
possible to collect centrally), AE and Concomitant Medication reviews, and 
continuation of TLS prophylaxis and infections (as applicable).
●
Instructions will be provided by AbbVie as to how a study site can initiate a 
DTP shipment using Marken, a global vendor selected by AbbVie to provide 
this service when necessary.
○
Marken is the preferred courier for DTP shipping; however, in extenuating 
circumstances, alternate local couriers may be allowed with prior approval 
from the AbbVie Clinical Contact (or designee) identified in Section 7.0.  
If Marken is not utilized, the study site is responsible for ensuring the 
courier will transport the study drug under appropriate temperature 
controlled conditions and require a signature for delivery.
●
Shipments may also include other non-drug study supplies (e.g., drug dosing 
diaries, 24-hour urine collection containers, etc.).  Subjects should provide 
dosing updates to study site staff during remote phone or video conference 
visits, and return diaries to the study site at the time of the next onsite visit.
●
Prior to arranging shipment, the study site should contact the subject to confirm 
the subject will be available to accept delivery of the shipment.
●
Shipments of study drugs from the study site to a subject's home will be 
appropriately temperature controlled (qualified shipper or temperature 
monitoring) within the labeled storage conditions.  Signature is required upon 
delivery; due to COVID-19 related social distancing, this may be provided by 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
106
the courier after delivery.  Documentation of the shipment is to be retained by 
the clinical site.
●
The site should contact the subject to confirm delivery of the shipment and the 
date and time of the next dose, and document this in the source documents.
●
AbbVie will not receive subject identifying information related to these 
shipments, as the study site will work directly with the courier.
                                                                                                                                                                              
The study site is responsible for meeting IRB/IEC reporting requirements for DTP 
shipments of study drug, and for obtaining consent to provide delivery information (which 
includes subject identifying information) to the courier and documenting this consent in 
source documents.
The study site must keep records of all shipments within the subject source 
documentation.
When DTP shipping is utilized, subjects are not to discard any study drug bottles and/or 
unused study drug.  The subject should return the study drug bottles and any unused study 
drug to the site at the time of the next onsite study visit unless the study site is directed 
otherwise by AbbVie.
Bortezomib should be administered at the study site; however, trained staff (site staff or 
home health) may administer subcutaneous bortezomib in the home setting when 
permitted by the country's regulations and after discussion and approval of the TA MD.

5.5.3
Method of Assigning Subjects to Treatment Groups
The IRT will randomize subjects into the 2 treatment arms in a 2:1 ratio 
(Venetoclax:Placebo).  Subject randomization will be stratified by prior exposure to 
bortezomib or other proteasome inhibitors (proteasome inhibitor-naïve versus proteasome 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
109
inhibitor-sensitive) and number of prior lines of therapy (1 versus 2 or 3).  The 
stratification factors used for the randomization should be the most recent values on the 
date of randomization.
A bottle number randomization schedule and a subject randomization schedule will be 
generated by the Clinical Statistics Department at AbbVie prior to the start of the study.  
A copy of all randomization schedules will be kept by the Clinical Statistics Department 
at AbbVie and a copy will be forwarded to the IRT vendor.
Japan Subjects Only: The first 12 subjects in Japan will be enrolled in the run-in phase.  
Separate randomization will be used for the first 12 subjects in the run-in phase in Japan, 
the remaining subjects in Japan and subjects in all countries expect Japan.  An identical 
procedure will be used in the three groups of subjects.  Subjects will be stratified based on 
prior exposure to bortezomib or other proteasome inhibitors (proteasome inhibitor naïve
versus sensitive) and the number of prior lines of therapy (1 versus 2 or 3).  There will be 
separate randomization lists for 4 strata within each of the three groups (Japan run-in, the 
rest of the Japan and the rest of the world).  Subjects within a stratum will be randomized 
to venetoclax and placebo arms in 2:1 ratio.  This procedure of randomization will ensure 
at least 6 subjects in Japan to be allocated in venetoclax arm in run-in phase.
5.5.4
Selection and Timing of Dose for Each Subject
Selection of the dose of venetoclax is discussed in Section 5.6.4.  Timing of doses is 
discussed in Section 5.5.1.
5.5.5
Blinding
5.5.5.1
Blinding of Investigational Product
The Investigator, the study site personnel and the subject will remain blinded to each 
subject's treatment with venetoclax/placebo throughout the course of the study.
All subjects will be treated with open-label bortezomib and dexamethasone.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
110
The IRT system can provide access to blinded subject treatment information during the 
study if identification of the study drug is required for medical emergency, i.e., situation 
in which the knowledge of the specific blinded treatment will affect the immediate 
management of the subject/subject's conditions (e.g., antidote is available).  AbbVie must 
then be notified within 24 hours of the blind being broken.  The date and reason that the 
blind was broken must be recorded in the source documentation and eCRF, as applicable.  
Un-blinding of subject treatment information in other exceptional circumstances will 
require approval from the AbbVie TA MD or designee.
5.5.5.2
Blinding of Data for Independent Data Monitoring 
Committee (IDMC)
An IDMC will periodically review the safety and efficacy data for this study in an un-
blinded fashion.  Aggregate blinded clinical safety and efficacy data will be reviewed on a 
real-time basis throughout the course of the study.  Once the final Overall Survival (OS) 
analysis is complete (refer to Section 8.1.5.5.2), a final review of safety and efficacy data 
will be conducted by the IDMC.  AbbVie will continue to monitor subjects' safety data 
after the final IDMC meeting.
Details of the IDMC review will be outlined in the IDMC Charter.
5.5.5.3
Unblinding Process
Once the final OS analysis is complete, an unblinding letter will be sent from the AbbVie 
TA MD to the Principal Investigator of each site taking part in the study.  The PI should 
notify study subjects of treatment allocation by preferred method (e.g., phone, letter) and 
document in the subject’s chart that the subject has been informed of treatment allocation 
and applicable safety information.
5.5.6
Treatment Compliance
The Investigator or his/her designated and qualified representatives will 
administer/dispense the study treatment only to subjects enrolled in the study in 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
111
accordance with the protocol.  The study treatment must not be used for reasons other 
than that described in the protocol.
5.5.7
Drug Accountability
The Investigator or his/her designated representatives will administer study treatment only 
to subjects enrolled in the study.  Documentation of the receipt of supplies will be 
supported by a signed and dated Proof of Receipt or similar document.  A current 
(running) and accurate inventory of study treatment will be kept by the site and will 
include lot number, Proof of Receipt number(s), bottle numbers, and the date on which the 
study treatment is dispensed or administered to the subject.
An overall accountability of the study treatment will be performed and verified by 
AbbVie or the designated monitor(s) throughout the study and at the study site Closeout 
Visit.  Upon completion or termination of the study, all original containers (containing 
partially used or unused study treatment) will be returned to AbbVie according to 
instructions from AbbVie or the designated monitor(s).  If prearranged between AbbVie 
and the site, destruction of used and unused study treatment will be performed at the site.  
Empty containers will be destroyed at the site.  Labels must remain attached to the 
containers.
5.6
Discussion and Justification of Study Design
5.6.1
Discussion of Study Design and Choice of Control Groups
This is a Phase 3, multicenter, randomized, double blind study to evaluate the efficacy and 
safety of venetoclax plus Bd compared to an active control of placebo plus Bd.  The 
choice of the control group allows for a double blinded assessment of the contribution of 
venetoclax to the safety and efficacy of the backbone regimen of Bd.
The proteasome inhibitor bortezomib combined with dexamethasone has proven 
therapeutic value and is considered to be a standard of care listed in the National 
Comprehensive Cancer Network and the European Society for Medical Oncology 
(ESMO) guidelines as a recognized treatment for patients with previously treated 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
112
MM.13,16,35  Given that bortezomib combined with dexamethasone is one of the standard 
of care therapies in the treatment of relapsed or refractory MM, it makes an ideal 
therapeutic regimen to be used as an active comparator in a randomized, controlled study 
designed to evaluate the therapeutic value of an investigational drug added to the 
bortezomib plus dexamethasone regimen.
5.6.2
Appropriateness of Measurements
Standard PK, statistical, clinical and laboratory procedures will be utilized in this study.
5.6.3
Suitability of Subject Population
Adult male and female subjects with relapsed or refractory MM who are considered 
sensitive or naïve to proteasome inhibitor and received 1 to 3 prior lines of therapy for 
multiple myeloma will be selected to participate in this study.  Due to the expected 
mechanism-based lymphopenia, subjects will be monitored to assess risk for infection.  
As a preventative measure, prophylaxis for viral, fungal, bacterial or Pneumocystis 
infections will be implemented when appropriate.
5.6.4
Selection of Doses in the Study
The dosage regimen of bortezomib and dexamethasone are the doses specified in relapsed 
or refractory multiple myeloma subjects on the bortezomib US package insert and the EU 
SmPC.  For the initial 8 cycles, the currently approved regimen of bortezomib with dosing 
on Days 1, 4, 8 and 11 every 21 days is used.  For extended therapy beyond 8 cycles, 
bortezomib is used per the US package insert on a maintenance schedule of weekly dosing 
on Days 1, 8, 15, 22 every 35 days.  This regimen allows patients who are responding to 
continue their treatment beyond 8 cycles with the less intense and better tolerated weekly 
regimen, which decreases the incidence of peripheral neuropathy, a key limiting toxicity 
with bortezomib.  Similar regimens have been used in other Phase 3 clinical studies with 
bortezomib-based therapies.36-38
The selected 800 mg dosage of venetoclax is based on the results from Study M12-901, a 
Phase 1b study of venetoclax plus Bd in relapsed or refractory multiple myeloma subjects.  
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
113
In this study venetoclax was administered until progression or unacceptable toxicity 
occurred and the maximum tolerated dose (MTD) of venetoclax plus Bd was not reached 
at the highest tested venetoclax dose of 1200 mg QD.  Exposure-response analyses of the 
efficacy and safety from Study M12-901 were conducted based on the available PK, best 
response (per the International Myeloma Working Group [IMWG] criteria), and safety 
(grade ≥ 3 anemia, thrombocytopenia, and neutropenia).  Anemia, thrombocytopenia, and 
neutropenia were selected as they are the toxicities relevant to the venetoclax experience 
to date.  At the time of the analysis, the venetoclax doses ranged from 50 to 1200 mg QD 
in these subjects and the duration of treatment ranged from 9 to 664 days.
Using a population PK exposure-response model, the dose-response relationships of 
efficacy and neutropenia were determined for subjects with typical PK in the population 
that will be enrolled in Study M14-031 (non-refractory to bortezomib and received 1 to 
3 prior treatments).  There was a high predicted probability of achieving MR (or better) 
across all venetoclax dosages in this population, while the probability of VGPR or better 
was predicted to increase with increasing doses through 1200 mg QD.  Similarly, 
neutropenia (grade ≥ 3) rates were generally low through doses of 800 mg QD, increasing 
thereafter.  No relationship between venetoclax exposure and anemia or thrombocytopenia 
was observed.  Based on these preliminary efficacy and safety results, and considering 
treatment compliance considerations, a venetoclax dose of 800 mg QD was selected in 
combination with BD.

6.1
Medical Complaints
The Investigator will monitor each subject for clinical and laboratory evidence of adverse 
events on a routine basis throughout the study.  The Investigator will assess and record 
any adverse event in detail including the date of onset, event diagnosis (if known) or 
sign/symptom, severity, time course (end date, ongoing, intermittent), relationship of the 
adverse event to study treatment, and any action(s) taken.  For serious adverse events 
considered as having "no reasonable possibility" of being associated with study treatment, 
the Investigator will provide an alternative cause of the event.  For adverse events to be 
considered intermittent, the events must be of similar nature and severity.  Adverse 
events, whether in response to a query, observed by site personnel, or reported 
spontaneously by the subject will be recorded.
All adverse events will be followed to a satisfactory conclusion.
6.1.1
Definitions
6.1.1.1
Adverse Event
An adverse event is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not 
necessarily have a causal relationship with this treatment.  An adverse event can therefore 
be any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal (investigational) 
product, whether or not the event is considered causally related to the use of the product.
Such an event can result from use of the drug as stipulated in the protocol or labeling, as 
well as from accidental or intentional overdose, drug abuse, or drug withdrawal.  Any 
worsening of a pre-existing condition or illness is considered an adverse event.  
Worsening in severity of a reported adverse event should be reported as a new adverse 
event.  Laboratory abnormalities and changes in vital signs are considered to be adverse 
events only if they result in discontinuation from the study, necessitate therapeutic 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
115
medical intervention, meet protocol specific criteria (see Section 6.1.7 regarding toxicity 
management) or if the Investigator considers them to be adverse events.
An elective surgery/procedure scheduled to occur during a study will not be considered an 
adverse event if the surgery/procedure is being performed for a pre-existing condition and 
the surgery/procedure has been pre-planned prior to study entry.  However, if the 
pre-existing condition deteriorates unexpectedly during the study (e.g., surgery performed 
earlier than planned), then the deterioration of the condition for which the elective 
surgery/procedure is being done will be considered an adverse event.
A treatment-emergent adverse event is defined as any adverse event with onset or 
worsening reported by a subject from the time that the first dose of venetoclax/placebo, 
bortezomib, or dexamethasone is administered until 30 days have elapsed following 
discontinuation of venetoclax/placebo, bortezomib, and dexamethasone administration.
6.1.1.2
Serious Adverse Events
If an adverse event meets any of the following criteria, it is to be reported to AbbVie as a 
serious adverse event (SAE) within 24 hours of the site being made aware of the serious 
adverse event:
Death of Subject
An event that results in the death of a subject.
Life-Threatening
An event that, in the opinion of the Investigator, would have 
resulted in immediate fatality if medical intervention had not 
been taken.  This does not include an event that would have 
been fatal if it had occurred in a more severe form.
Hospitalization or 
Prolongation of 
Hospitalization
An event that results in an admission to the hospital for any 
length of time or prolongs the subject's hospital stay.  This 
does not include an emergency room visit or admission to an 
outpatient facility.
Congenital Anomaly
An anomaly detected at or after birth, or any anomaly that 
results in fetal loss.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
116
Persistent or 
Significant 
Disability/Incapacity
An event that results in a condition that substantially 
interferes with the activities of daily living of a study 
subject.  Disability is not intended to include experiences of 
relatively minor medical significance such as headache, 
nausea, vomiting, diarrhea, influenza, and accidental trauma 
(e.g., sprained ankle).
Important Medical 
Event Requiring 
Medical or Surgical 
Intervention to 
Prevent Serious 
Outcome
An important medical event that may not be immediately 
life-threatening or result in death or hospitalization, but 
based on medical judgment may jeopardize the subject and 
may require medical or surgical intervention to prevent any 
of the outcomes listed above (i.e., death of subject, 
life-threatening, hospitalization, prolongation of 
hospitalization, congenital anomaly, or persistent or 
significant disability/incapacity).  Additionally, any elective 
or spontaneous abortion or stillbirth is considered an 
important medical event.  Examples of such events include 
allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or 
convulsions that do not result in inpatient hospitalization, or 
the development of drug dependency or drug abuse.
For serious adverse events with the outcome of death, the date and cause of death will be 
recorded on the appropriate case report form.  Deaths related to disease progression will 
not be recorded as adverse events (see Section 6.1.1.3).
6.1.1.3
Adverse Events Expected Due to Study Related Endpoints
6.1.1.3.1
Deaths
For this protocol, overall survival is an efficacy endpoint.  Deaths that occur during the 
protocol specified adverse event collection period (Section 6.1.4 and Figure 2) that are 
attributed by the investigator solely to progression of multiple myeloma should be 
recorded only on the Death eCRF and the Study Completion Form eCRF.  All other 
on-study deaths, regardless of relationship to study treatment, must be recorded on the 
Adverse Event eCRF and immediately reported to the Sponsor (Section 6.1.5).
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
117
Death should be considered an outcome and not a distinct event.  The event or condition 
that caused or contributed to the fatal outcome should be recorded as the single medical 
concept on the Adverse Event eCRF.  Generally, only one such event should be reported.  
The term "sudden death" should only be used for the occurrence of an abrupt and 
unexpected death due to presumed cardiac causes in a patient with or without pre-existing 
heart disease, within 1 hour of the onset of acute symptoms or, in the case of an 
unwitnessed death, within 24 hours after the patient was last seen alive and stable.  If the 
cause of death is unknown and cannot be ascertained at the time of reporting, 
"unexplained death" should be recorded on the Adverse Event eCRF.  If the cause of 
death later becomes available (e.g., after autopsy), "unexplained death" should be replaced 
by the established cause of death.
6.1.1.3.2
Lack of Efficacy or Worsening of Disease
Events that are clearly consistent with the expected pattern of progression of the 
underlying disease are also considered an expected outcome for this study and will not be 
subject to expedited reporting.
6.1.2
Adverse Event Severity
The Investigator will rate the severity of each adverse event according to the National 
Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE 
Version 4.03).39  If a reported adverse event increases in severity, the initial adverse event 
should be given an outcome date and a new adverse event reported to reflect the change in 
severity.  For all reported serious adverse events that increase in severity, the 
supplemental eCRFs also need to be updated to reflect the change in severity.
For adverse events not captured by the Common Terminology Criteria, the following 
should be used:
Grade 1
The adverse event is transient and easily tolerated by the subject (mild).
Grade 2
The adverse event causes the subject discomfort and interrupts the 
subject's usual activities (moderate).
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
118
Grade 3
The adverse event causes considerable interference with the subject's 
usual activities and may be incapacitating (moderate to severe).
Grade 4
The adverse event is life threatening requiring urgent intervention 
(severe).
Grade 5
The adverse event resulted in death of the subject (severe).
6.1.3
Relationship to Study Treatment
The Investigator will use the following definitions to assess the relationship of the adverse 
event to the use of the study treatment:
Reasonable 
Possibility
An adverse event where there is evidence to suggest a causal 
relationship between the study treatment and the adverse event.
No Reasonable 
Possibility
An adverse event where there is no evidence to suggest a causal 
relationship between the study treatment and the adverse event.
The Investigator will assess the relationship of each adverse event to venetoclax, to 
bortezomib, and to dexamethasone.  Some events may be reasonably related to more than 
one drug or to none.  For causality assessments, events assessed as having a reasonable 
possibility of being related to the study treatment will be considered "associated."  Events 
assessed as having no reasonable possibility of being related to study treatment will be 
considered "not associated."  In addition, when the Investigator has not reported causality 
or deemed it not assessable, AbbVie will consider the event associated to study treatment.
If an Investigator's opinion of no reasonable possibility of being related to the study 
treatment is given, an "Other" cause of event must be provided by the Investigator for the 
serious adverse event.
6.1.4
Adverse Event Collection Period
All protocol-related serious adverse events and nonserious adverse events must be 
collected from the signing of the study specific informed consent until study treatment 
administration.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
119
Serious and nonserious adverse events occurring after the study-specific informed consent 
is signed but prior to the initial dose of study treatment will be collected only if they are 
considered by the Investigator to be causally related to the study-required procedures.
All serious and nonserious adverse events reported from the time of study treatment 
administration until 30 days following discontinuation of study treatment administration 
have elapsed will be collected, whether elicited or spontaneously reported by the subject.
Adverse event information will be collected as shown in Figure 2.

Only if considered by the Investigator to be causally related to study-required procedures.
6.1.5
Adverse Event Reporting
In the event of a serious adverse event, whether associated with the study treatment or not, 
the Investigator will notify Clinical Pharmacovigilance within 24 hours of the site being 
made aware of the serious adverse event by entering the serious adverse event data into 
EDC RAVE® system.  Serious adverse events that occur prior to the site having access to 
the RAVE® system, or if RAVE® is not operable, should be documented on the SAE Non-
CRF forms and emailed (preferred route) or faxed to Clinical Pharmacovigilance within 
24 hours of the site or Investigator being made aware of the serious adverse event.

AbbVie will be responsible for Suspected Unexpected Serious Adverse Reactions 
(SUSAR) reporting for the Investigational Medicinal Product (IMP) in accordance with 
Global and Local Regulation, and Appendix A of the Investigator Brochure will serve as 
the Reference Safety Information (RSI) for the AbbVie IMP.  The RSI in effect at the start 
of a Drug Safety Update Report (DSUR) reporting period serves as the RSI during the 
reporting period.  For follow-up reports, the RSI in place at the time of occurrence of the 
"suspected" Serious Adverse Reaction will be used to assess expectedness.  For 
comparator products being used as non-AbbVie IMPs, the SmPC will serve as the 
Reference Safety Information (RSI) for those non-AbbVie products.
The following definitions will be used for Serious Adverse Reactions (SAR) and 
Suspected Unexpected Serious Adverse Reaction (SUSAR):
SAR
Defined as all noxious and unintended responses to an IMP related 
to any dose administered that result in death, are life-threatening, 
require inpatient hospitalization or prolongation of existing 
hospitalization, result in persistent or significant disability or 
incapacity, or are a congenital anomaly or birth defect.
SUSAR
A suspected SAR:  refers to individual SAE case reports from 
clinical trials where a causal relationship between the SAE and the 
IMP was suspected by either the sponsor or the investigator, is not 
listed is the applicable Reference Safety Information, and meets one 
of the following serious criteria:  results in death, is life-threatening, 
requires hospitalization or prolongation of an existing 
hospitalization, results in persistent or significant disability or 
incapacity, or is a congenital anomaly or birth defect.  All 
individually reported SARs are considered suspected.
In Japan, the principal investigator will provide documentation of all serious adverse 
events to the Director of the investigative site and the Sponsor.

COVID-19 Pandemic-Related Acceptable Protocol Modification:
Supplemental study case report forms should be completed in the event of COVID-19 
related missed/virtual visits, study drug interruptions or discontinuations, or adverse 
events (including capture of specific signs/symptoms of infection and testing results).
COVID-19 infections should be captured as adverse events.  If the event meets the criteria 
for a serious adverse event (SAE), then follow the SAE reporting directions per the 
protocol.  The following COVID-19 related supplemental eCRFs should be completed 
(for both serious and non-serious events):
●
COVID-19 Supplemental Signs/Symptoms
●
COVID-19 Status Form
Subjects with a confirmed (viral test positive) or suspected COVID-19 infection must 
interrupt all study drugs until the COVID-19 viral clearance criteria in Section 6.2 are 
met.  There are no time limits for study drug interruption as long as no permanent study 
discontinuation criteria have been met.  The investigator should notify the AbbVie TA 
MD or designee listed above before reintroducing any study drugs in subjects with 
confirmed or suspected COVID-19 infection.
6.1.6
Pregnancy
Pregnancy in a study subject must be reported to an AbbVie representative (Section 6.1.5) 
within 1 working day of the site becoming aware of the pregnancy.  Subjects who become 
pregnant during the study must be discontinued (Section 5.4.1).
All subjects should be informed that contraceptive measures (refer to Inclusion Criteria 
for the details on contraception) should be taken throughout the study and for at least 
90 days post last dose of study treatment.  Male subjects should inform their partner(s) 
that the effects of Venetoclax on an unborn fetus or embryo in humans are unknown.  
Information regarding a pregnancy occurrence in a study subject and the outcome of the 
pregnancy will be collected.  In the event of a pregnancy occurring in the partner of an 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
123
enrolled subject, written informed consent for release of medical information from the 
partner must be obtained prior to the collection of any pregnancy-specific information, 
and the pregnancy will be followed to outcome.
Pregnancy in a study subject is not considered an adverse event.  The medical outcome for 
either mother or infant, meeting any serious criteria including an elective or spontaneous 
abortion, is considered a serious adverse event and must be reported to AbbVie within 24 
hours of the site becoming aware of the event.
6.1.7
Toxicity Management
6.1.7.1
Management of Cytopenias and Infection
Venetoclax could lead to suppression of lymphocytes (B and T sub-types).  In addition, 
clinically significant neutropenia may also be observed in this study.  Both lymphopenia 
and neutropenia could increase the risk for infections, including opportunistic infections.  
All subjects receiving treatment with venetoclax/placebo in combination with a 
proteasome inhibitor must receive antibiotic prophylaxis with Bactrim forte® (1 tablet 
3 times a week) or equivalent therapy while on treatment.  Additionally, Levofloxacin 
(500 mg daily, adjusted for renal function as necessary) or equivalent antibiotic therapy 
per institutional guidelines must be administered for the first 90 days on study and when 
Grade 4 neutropenia develops (ANC < 500 cells/µL) and continued until the neutropenia
improves to Grade 3 or better (ANC > 500 cells/µL).  Subjects may receive antibiotic 
prophylaxis for at least 30 days upon disease progression or after the discontinuation of 
the proteasome inhibitor and/or venetoclax/placebo at the discretion of the investigator.  
Furthermore, it is recommended that subjects deemed at high risk of infection may receive 
immunoglobulin replacement therapy (i.e., IV immunoglobulin) per institutional 
guidelines or at the Investigator's discretion.
If the patient has hypersensitivity to these agents or develops unacceptable toxicity or 
intolerance, and a suitable alternative agent is not available, the subject may be removed 
from this treatment in consultation with the AbbVie Medical Monitor.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
124
The use of antibiotics that are moderate or strong CYP3A4 inhibitors should be avoided 
or used with caution and with appropriate dose modification as per protocol.
For all other subjects on venetoclax/placebo (not in combination with a proteasome 
inhibitor), prophylaxis should be considered at the Investigator's discretion.  Anti-
infective prophylaxis and G-CSF for the management of neutropenia may be considered 
per institutional guidelines.  Note:  Potential for drug-drug interactions should be 
considered.  Please refer to Appendix I for a description of excluded and cautionary 
medications.  
All antibiotic and supportive therapies are not required but may be continued at the 
discretion of the investigator for subjects in Arm 2 (Placebo + Bd) once unblinded.
All subjects with MM receiving venetoclax/placebo should be closely monitored for 
infections and in the event of a Grade ≥ 3 or serious infection, treatment with 
venetoclax/placebo should be interrupted, and upon resolution, treatment can be resumed 
at a reduced dose or discontinued, depending on Investigator's clinical judgment. 
Note:  Please refer to Table 8 for guidance on dose interruptions and/or reductions related 
to hematological and non-hematological toxicities.
All anti-infective prophylaxis measures and growth factor use should be appropriately 
recorded in the eCRF.
6.1.7.2
Management of Tumor Lysis Syndrome
TLS has been reported in patients with multiple myeloma with significant disease burden 
when treated with bortezomib or dexamethasone because of the potential for rapid onset 
of cell lysis with this agent.40  TLS has also been reported in patients with chronic 
lymphocytic leukemia with significant tumor burden when initiating venetoclax (initial 
5 weeks period of tumor debulking)12,13  No TLS event has been reported in the Phase 1 
studies with venetoclax plus Bd in multiple myeloma.

Subjects with high tumor burden (e.g., Durie-Salmon or International Staging System 
[ISS] Stage II/III), rapidly increasing M-protein or light chains or high proliferative 
activity, plasmablastic morphology, unfavorable karyotype or compromised renal function 
(CrCl < 50 mL/minute) may be at higher risk of developing TLS.41
Consider TLS prophylaxis with oral hydration (at least 1 – 2 liters, as tolerable, each day) 
in all subjects at least 72 hours prior to the first day of dosing with venetoclax/placebo.  
Prophylaxis with uric acid reducing agents may be required for subjects with high uric 
acid levels.  Monitor for clinical and laboratory evidence of TLS during treatment, and 
manage abnormalities in serum creatinine, uric acid and electrolytes promptly.  For 
subjects at higher risk, more intensive measures (e.g., intravenous hydration, frequent 
monitoring of labs, hospitalization, etc.) should be considered at the Investigator 
discretion.  All TLS prophylaxis measures should be appropriately recorded in the eCRF.
6.2
Guidelines for Dose Modifications and Treatment
If the dose of one drug in the study treatment (i.e., bortezomib, dexamethasone, or 
venetoclax/placebo) is delayed outside of the protocol allowed window or interrupted for 
any reason (i.e., – subject missed dose, dose held due to toxicity, etc.), the dose will be 
considered missed and the subject will continue on in the cycle (i.e., – if Cycle 2 Day 1 
dose of bortezomib is held and not completed with ±1 day window, Cycle 2 Day 1 would 
be considered missed and subject would continue to be evaluated for dosing at Cycle 2 
Day 4).  If a dose is held, all assessments listed for that day would still be completed, with 
the exception of PK samples.  Every effort should be made to follow the planned dosing 
schedule; however, delays of up to 7 days in the initiation of a cycle, beginning at Cycle 2 
Day 1, due to toxicity or scheduling issues will be allowed.
The subject will be considered still on protocol treatment as long as at least one of 
the specified drugs in the study treatment is being administered.  
Subjects experiencing a 21-day delay in all drugs that are part of the study treatment 
(bortezomib, dexamethasone, and venetoclax/placebo) due to an AE(s) related to study 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
126
treatment should be discontinued from study treatment.  Subjects experiencing delays 
unrelated to study treatment, for example due to radiation therapy may delay study 
treatment up to 42 days.  Delays greater than 21 days must be discussed with the TA MD 
or designee (refer to Section 6.1.5).
Interruption/Discontinuation of Study Drug Due to Confirmed or Suspected 
COVID-19 Infection:
Subjects with a confirmed (viral test positive) or suspected COVID-19 infection must 
interrupt all study drugs until the following COVID-19 viral clearance criteria are met and 
COVID-19 related complications do not change the subject's risk/benefit ratio per 
Investigator assessment.
Confirmed COVID-19 infection:
●
Symptomatic subjects:  At least 2 negative viral tests in a row, ≥ 24 hours apart 
after at least 14 days have passed since recovery, defined as resolution of fever 
without use of antipyretics and improvement in respiratory symptoms (e.g., 
cough, shortness of breath)
●
Asymptomatic subjects:  At least 2 negative viral tests in a row, ≥ 24 hours 
apart after at least 14 days have passed since prior positive result (note:  
subjects who develop symptoms will follow guidance above for symptomatic 
subjects)
Suspected COVID-19 infection:
●
Subjects with suspected COVID-19 infection should interrupt treatment with 
study drugs while viral testing is pending.  Treatment may be reinitiated upon 
confirmation of negative viral test result and notification to the AbbVie TA MD 
or designee.
The TA MD should be notified by the PI of any modification in planned study drug 
administration due to COVID-19.  In addition, the investigator should contact the 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
127
AbbVie TA MD before reintroducing any study drugs in subjects with confirmed or 
suspected COVID-19 infection.
Interruptions in study drug dosing due to the above COVID-19 testing guidance for 
subjects must be discussed with the AbbVie TA MD, along with the possibility of 
premature discontinuation from the study drug dosing period.  There are no time limits for 
study drug interruption if no permanent study discontinuation criteria have been met.  For 
subjects that experienced study drug interruptions greater than 42 days, two IMWG 
samples must be taken in order to rule out progressive disease prior to restarting study 
drug.  Follow protocol Section 5.3.7.1, Section 5.4.1, and Appendix G for subjects who 
discontinue study drug.
Frequency or timing of COVID-19 testing and intervals between testing for the above 
viral clearance criteria may be adjusted to account for epidemiologic trends, updated 
information regarding infectivity, and local/institutional guidelines.
COVID-19 Pandemic-Related Acceptable Protocol Modification:
Subjects who cannot attend an onsite visit to receive scheduled administration of
bortezomib should interrupt treatment with bortezomib until the subject is able to attend 
the study visit for treatment upon further discussion with AbbVie TA MD or designee.
At this time, dose holds are not recommended, unless for infections or other AEs 
according to the protocol. The Investigator should evaluate the benefit risk for each study 
patient and treat accordingly, even if this results in temporarily withholding treatment.
●
Subject restart after interruption may be allowed following the instructions 
under "Interruption/Discontinuation of Study Drug Due to Confirmed or 
Suspected COVID-19 Infection" in Section 6.2 above.
●
Permanent discontinuation is not recommended, even if a longer treatment free 
interval will occur.  These cases should be assessed on a case-by-case basis 
with the AbbVie TA MD or designee.

If the dose of venetoclax/placebo at dose level –3 is not tolerable, then no further 
reductions will be allowed and venetoclax/placebo should be discontinued.  Upon 
resolution of the AE leading to dose reduction, the dose of venetoclax/placebo can be 
increased once following Table 7 guidelines, based on the Investigator's clinical 
judgment.  If the AE recurs upon increasing the dose of venetoclax/placebo, then the 
subject should remain at the reduced and tolerated dose level.  Guidelines in Table 9
should also be followed for venetoclax/placebo-toxicity related dose reductions when 
moderate or strong CYP3A inhibitors are concomitantly administered.

6.2.2
Dose Modifications for Moderate or Strong CYP3A Inhibitors 
Used with Venetoclax/Placebo
Use of venetoclax/placebo with moderate or strong CYP3A4 inhibitors should be avoided 
and the investigator should consider alternative medications.  If the administration of a 
moderate or strong CYP3A4 is absolutely necessary based on the investigator's clinical 
judgment, then the venetoclax/placebo dose should be reduced during the period it is co-
administered with a moderate or strong CYP3A4.  Dose reductions for venetoclax/placebo 
dose levels used with moderate and strong CYP3A inhibitors are provided on Table 9.  
Subjects should be monitored more closely for signs of toxicities and the dose may need 
to be further adjusted.  After discontinuation of CYP3A inhibitor, wait for 3 days before 
venetoclax/placebo dose is increased back to previous dose level.

Product Complaint
6.3.1
Definition
A Product Complaint is any Complaint (see Section 6.0 for the definition) related to the 
biologic or drug component of the product.
For a product this may include, but is not limited to, damaged/broken product or 
packaging, product appearance whose color/markings do not match the labeling, labeling 
discrepancies/inadequacies in the labeling/instructions (example:  printing illegible), 
missing components/product, or packaging issues.
Any information available to help in the determination of causality to the events outlined 
directly above should be captured.
6.3.2
Reporting
Product Complaints concerning the investigational product must be reported to the 
Sponsor within 1 business day of the study site's knowledge of the event via the Product 
Complaint form.  Product Complaints that occur during the study will be followed-up to a 
satisfactory conclusion.  All follow-up information is to be reported to the Sponsor (or an 
authorized representative) and documented in source as required by the Sponsor.  Product 
Complaints associated with adverse events will be reported in the study summary.  All 
other complaints will be monitored on an ongoing basis.
Product Complaints may require return of the product with the alleged complaint 
condition.  In instances where a return is requested, every effort should be made by the 
Investigator to return the product within 30 days.  If returns cannot be accommodated 
within 30 days, the site will need to provide justification and an estimated date of return.
The description of the complaint is important for AbbVie in order to enable AbbVie to 
investigate and determine if any corrective actions are required.

Statistical and Analytical Plans
8.1.1
Definition for Analysis Populations
Intent-To-Treat (ITT) analysis set consists of all randomized subjects.  The data from the 
ITT population will be analyzed by the treatment group assignment given at the time of 
randomization, even if the subject does not receive the correct treatment or is not 
compliant to the protocol procedures.
Unless otherwise noted, the ITT analysis set will be used for baseline characteristics and 
efficacy analyses.
Safety analysis set consists of all randomized subjects who take at least one dose of study 
drug.  Patients who received venetoclax at the first actual dosing day will be considered as 
venetoclax plus Bd group and otherwise they will be considered as placebo plus Bd 
group.
The safety analysis set will be used for safety analyses.
8.1.2
Baseline Characteristics
All baseline summary statistics and analyses will be based on characteristics prior to the 
initiation of any component of study treatment (or randomization for non-treated 
subjects).  Unless otherwise stated, baseline for a given variable will be defined as the last 
value for that variable obtained prior to the first dose of any component of study treatment 
(or randomization for non-treated subjects).
Continuous demographic data (e.g., age, height, and weight) will be summarized with 
means, standard deviation, minimum, maximum, and range.  Frequencies and percentages 
will be computed for categorical data (e.g., sex, race, number of prior therapies [1 versus 
2 versus 3], prior exposure to bortezomib or other proteasome inhibitors [proteasome 
inhibitor-sensitive versus proteasome inhibitor-naïve], MM stage [I versus II versus III], 
biomarkers, geography [North America versus EU versus Rest of World]), and baseline 
ECOG performance status.

Efficacy Endpoints
8.1.3.1
Primary Efficacy Endpoint
The primary endpoint is PFS based on IMWG criteria for multiple myeloma 
(Appendix J) 13,14 per IRC assessment.
For a given subject, PFS is defined as the number of days from the date the subject was 
randomized to the date of the first documented PD or death due to any cause, whichever 
occurs first.  All events of PD will be included, regardless of whether the event occurred 
while the subject was still taking study drug or had previously discontinued study drug.  
Events of death will be included for subjects who had not experienced an event of PD.  If 
the subject does not have an event of PD and the subject has not died, the subject's data 
will be censored.  Detailed event and censoring information for PFS are provided in

8.1.4
Timing of Efficacy Analyses and Safety Evaluations
Efficacy and safety analyses will be performed when approximately 136 PFS events per 
IRC assessment are observed.  If the observed treatment benefit with respect to PFS is 
both statistically and clinically significant, patients will still continue to be followed for 
overall survival with no treatment cross-over.
8.1.5
Statistical Analyses of Efficacy
8.1.5.1
Primary Analysis of Efficacy
The study is designed to test the following primary statistical hypothesis:
: (	)Venetoclax + Bd = (	)Placebo + Bd   vs.  : (	)Venetoclax +Bd ≠(	)Placebo + Bd ,
where S(t) is the survivorship function of PFS at time t.
For PFS, a stratified two-sided log-rank test with two-sided type-I error rate of α = 0.05 
(one-sided type I error rate of α = 0.025) will be used to test the primary null hypothesis.  
The hazards ratio (HR) for treatment effect will be estimated and its two-sided 95% 
confidence interval will be provided.  The estimation will be based on a Cox's 
proportional hazards model with treatment and stratification factors included.
In addition, survivorship functions will be estimated by using Kaplan-Meier product-limit 
method.  Estimated survival curves will be presented.  The estimations will be performed 
by treatment group.  If reached, median PFS time and its two-sided 95% confidence 
intervals will be presented by treatment group.
8.1.5.2

method.  Estimated survival curves will be presented.  The estimations will be performed 
by treatment group.  If reached, median time to event and its two-sided 95% confidence 
intervals will be presented by treatment group.
The OS will be analyzed by using a stratified two-sided 3-look group sequential log-rank 
test with a cumulative two-sided type-I error rate of α = 0.05 (one-sided type I error rate 
of α = 0.025).  The hazards ratio for treatment effect will be estimated and its two-sided 
95% confidence interval will be provided.  The estimation will be based on a Cox's 
proportional hazards model with treatment and stratification factors in it.
In addition, survivorship functions will be estimated by using Kaplan-Meier product-limit 
method.  Estimated survival curves will be presented.  The estimations will be performed 
by treatment group.  If reached, median OS time and its two-sided 95% confidence 
intervals will be presented by treatment group.
DOR will be analyzed only based on data from responders (PR or better) out of the ITT 
analysis set.

changes: 
1.
PFS based on assessment by Investigator.
2.
Using the actual event date of PD or death as event date, regardless of the number 
of preceding missing assessments.
3.
Not considering taking new anticancer therapy as a reason for censoring.  
4.
A robustness analysis will be performed using a stratified, adjusted Cox model, 
i.e., the MODEL statement will include the treatment group variable; and, e.g., age 
group (< 65 years/≥ 65 years), renal function, cytogenetic (high risk/standard risk), 
prior stem cell transplant (yes/no), BCL-2 expression (high/low) and MM stage as 
covariates.  The stratification factors will be reflected in the STRATA statement.  
HR and 2-sided 95% CIs will be provided.  Covariates with large number of 
missing data or small number of subjects within a category may be excluded or 
combined as appropriate.
Supportive subgroup analysis will be performed for the primary endpoint PFS and 
alternative additional sensitivity and supportive efficacy statistical analyses may be 
performed if deemed necessary and helpful in understanding the drug effect, which will 
be specified in the SAP.
8.1.5.5
Interim Analysis
8.1.5.5.1
Progression Free Survival
There is no Interim Analysis for Progression Free Survival.
8.1.5.5.2
Overall Survival
The OS will be analyzed by using a stratified two-sided 3-look group sequential log-rank 
test with a cumulative two-sided type-I error rate of α = 0.05 (one-sided type I error rate 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
147
of α = 0.025).  A separate α-spending approach will be used for OS.  The final OS 
analysis will be performed when approximately 116 OS events are observed.  The interim 
analyses for OS will be considered at the time of the PFS analysis and when 
approximately 75% of the total 116 OS events are observed (87 OS events).  
8.1.5.6
Multiplicity Adjustments
Statistical tests for the secondary endpoints will be implemented in the testing strategy to 
maintain family-wise two-sided type I error rate at 0.05.  Each of these tests will be 
performed at an overall two-sided significance level of 0.05.  Statistical testing of the 
secondary endpoints will be performed only if the primary efficacy analysis of PFS is 
significant.
The testing order and details of testing procedures will be provided in the SAP.
8.1.6
Safety Assessments
The safety of venetoclax plus Bd and placebo plus Bd will be assessed by evaluating 
study treatment exposure, adverse events, serious adverse events, deaths, and changes in 
laboratory determinations and vital sign parameters.
8.1.7

8.1.7.1
Duration of Study Treatment
A summary of the number of days and/or cycles subjects were exposed to study treatment 
will be provided.
8.1.7.2
Adverse Events
Analyses of adverse events will include only "treatment-emergent" events, i.e., those that 
have an onset on or after the day of the study treatment.  Analyses will not include those 
that have an onset greater than 30 days after the last dose of the study drug.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
148
Treatment-emergent adverse events will be coded and summarized by system organ class 
and preferred term according to the Medical Dictionary for Regulatory Activities 
(MedDRA) adverse event coding dictionary.  The percentage of subjects experiencing an 
adverse event at a given severity, NCI CTCAE version 4.03 toxicity grade and 
relationship to study treatment will be provided.
8.1.7.3
Serious Adverse Events
Serious adverse events will be summarized using the same methods as adverse events 
described above in Section 8.1.7.2.
8.1.7.4
Deaths
The number of subject deaths will be summarized 1) for deaths occurring while the 
subject was still receiving study drug in this study, 2) for deaths occurring off treatment 
within 30 days after the last dose of study drug, and 3) for all deaths in this study 
regardless of the number of days after the last dose of study drug.
8.1.7.5
Longitudinal Analyses of Laboratory and Vital Signs Data
Changes from baseline may be summarized for each scheduled post-baseline visit and for 
the Treatment Completion Visit for hemoglobin, platelet, neutrophil, absolute leukocyte 
count, creatinine, and calcium, and vital sign parameters.  If more than one measurement 
exists for a subject on a particular day, an arithmetic average will be calculated.  This 
average will be considered to be that subject's measurement for that day.  Post-baseline 
measurements more than 30 days after the last dose of randomized study drug will not be 
included.  Subjects that do not have a baseline measurement or do not have any 
post-baseline measurements will not be included.
8.1.7.6
Analyses of Laboratory Data Using NCI CTCAE
Where applicable, laboratory values will be categorized according to the NCI CTCAE 
version 4.03 grades, and shifts from baseline grade to maximum and final post-baseline 
grades will be assessed.  The baseline and final grades will be defined respectively as the 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
149
grade of the last measurement collected prior to the first dose of any component of study 
treatment, and as the grade of the last post-baseline measurement collected no more than 
30 days after the last dose of study drug.  If multiple values are available for a post 
baseline measurement, then the value with the highest NCI CTCAE grade will be used in 
the assessment of shift.
Detailed listings of data for subjects experiencing NCI CTCAE Grade 3 to 4 blood 
chemistry and hematology values will be provided.  All measurements collected, 
regardless of the number of days after the last dose of study drug, will be included in these 
listings.
8.1.7.7
Analyses of Vital Signs Using Criteria for Potentially 
Clinically Significant Vital Sign Values
Detailed listings of data for subjects experiencing potentially clinically significant vital 
sign values according to the AbbVie-defined criteria for vital sign values will be provided.  
All measurements collected, regardless of the number of days after the last dose of study 
drug, will be included in these listings.
8.1.7.8
Pharmacokinetics
Plasma concentrations of venetoclax and bortezomib (and dexamethasone, JAPAN
subjects only) will be tabulated for each subject by visit.
An analysis of venetoclax plasma concentrations may be performed using a nonlinear 
mixed effect population PK modeling approach.  The results from the population PK 
analysis may not be reported in the clinical study report.  Additional analyses may be 
performed if useful in the interpretation of the data.
8.2
Determination of Sample Size
In order to calculate the required number of PFS events, median PFS of placebo plus Bd 
and venetoclax plus Bd are assumed to be 9 months and 16.25 months, respectively 
(HR = 0.554, under the assumption of proportionality).  Log-rank test with two-sided 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
150
type I error rate of α = 0.05 (one-sided type I error rate of α = 0.025) and power of 
1 – β = 90% is used for sample size calculations.  
Under the assumptions above and using a 2:1 randomization ratio to the two arms 
(venetoclax plus Bd versus placebo plus Bd) a total of 136 PFS events per IRC 
assessment are required.  To observe 136 PFS events per IRC assessment, approximately 
280 subjects will be randomized.
With accrual assumed as in Table 17, and the assumed overall dropout rate of 16%, the 
accrual of 280 subjects will take approximately 15 months and 136 PFS events per IRC 
assessment are expected to be reached after approximately 26 months.
The accrual and the blinded PFS rate will be assessed during the conduct of the trial to 
determine if the sample size should be adjusted to ensure timely achievement of the 
required 136 PFS events per IRC assessment.

In order to calculate the required number of OS events, median OS of placebo plus Bd and 
venetoclax plus Bd are assumed to be 24 months and 40 months, respectively (HR = 0.6, 
under the assumption of proportionality).  The study design includes 2 pre-specified 
interim analyses for the secondary endpoint OS.  The final OS analysis will be performed 
when approximately 116 OS events are observed.  The first OS interim analysis will be at 
the time of PFS analysis.  The second OS interim analysis will be based on approximately 
75% of the total 116 OS events (87 OS events).  Two-sided log-rank test with a 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
151
cumulative two-sided type I error rate of α = 0.05 (one-sided type I error rate of 
α = 0.025) is used for the 3-look group sequential plan.  Group sequential plan using Lan 
and DeMets43 α-spending approach with O'Brien-Fleming type boundaries will be applied 
for the OS efficacy analyses.
Approximately 58 OS events are expected at the time of PFS analysis.

Ethics
9.1
Independent Ethics Committee (IEC) or Institutional Review 
Board (IRB)
Good Clinical Practice (GCP) requires that the clinical protocol, any protocol 
amendments, the Investigator's Brochure, the informed consent and all other forms of 
subject information related to the study (e.g., advertisements used to recruit subjects) and 
any other necessary documents be reviewed by an IEC/IRB.  The IEC/IRB will review the 
ethical, scientific and medical appropriateness of the study before it is conducted.  
IEC/IRB approval of the protocol, informed consent and subject information and/or 
advertising, as relevant, will be obtained prior to the authorization of drug shipment to a 
study site.
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20
152
Any amendments to the protocol will require IEC/IRB approval prior to implementation 
of any changes made to the study design.  The Investigator will be required to submit, 
maintain and archive study essential documents according to International Conference in 
Harmonization (ICH) GCP.
Any serious adverse events that meet the reporting criteria, as dictated by local 
regulations, will be reported to both responsible Ethics Committees and Regulatory 
Agencies, as required by local regulations.  During the conduct of the study, the 
Investigator should promptly provide written reports (e.g., ICH Expedited Reports, and 
any additional reports required by local regulations) to the IEC/IRB of any changes that 
affect the conduct of the study and/or increase the risk to subjects.  Written documentation 
of the submission to the IEC/IRB should also be provided to AbbVie.
9.2
Ethical Conduct of the Study
The study will be conducted in accordance with the protocol, ICH GCP guidelines, 
applicable regulations and guidelines governing clinical study conduct and ethical 
principles that have their origin in the Declaration of Helsinki.  Responsibilities of the 
clinical Investigator are specified in Appendix A.
In the event a significant disaster/crisis (e.g., epidemic/pandemic, natural disaster, 
conflict/combat) occurs leading to difficulties in performing protocol-specified 
procedures, AbbVie will engage with study site personnel in efforts to ensure the safety of 
subjects, maintain protocol compliance, and minimize risks to the integrity of the study 
while trying to best manage subject continuity of care.  This may include alternative 
methods for assessments (e.g., phone contacts or virtual site visits), alternative locations 
for data collection (e.g., use of a local laboratory instead of a central lab), and shipping 
investigational product and/or supplies direct to subjects to ensure continuity of treatment 
where allowed.  COVID-19 pandemic-related acceptable protocol modifications are 
detailed throughout the protocol.  In all cases, these alternative measures must be allowed 
by local regulations and permitted by IRB/IEC.  Investigators should notify AbbVie if any 
urgent safety measures are taken to protect the subjects against any immediate hazard.

9.3
Subject Information and Consent
The Investigator or his/her representative will explain the nature of the study to the 
subject, and answer all questions regarding this study.  Prior to any study-related 
screening procedures being performed on the subject, the informed consent statement will 
be reviewed and signed and dated by the subject, the person who administered the 
informed consent, and any other signatories according to local requirements.  A copy of 
the informed consent form will be given to the subject and the original will be placed in 
the subject's medical record.  An entry must also be made in the subject's dated source 
documents to confirm that informed consent was obtained prior to any study-related 
procedures and that the subject received a signed copy.
Information regarding incentives for subjects and information regarding provisions for 
treating and/or compensating subjects who are harmed as a consequence of participation 
in the study can be found in the informed consent form.
In the event a subject withdraws consent to participate from the study, stored biomarker 
samples will continue to be used for research and analysis.  In the event that a subject 
would like to withdraw consent for research using these samples, the subject may request 
that their samples be withdrawn.  Once AbbVie receives the request, remaining biomarker 
samples will be destroyed.  If the subject changes his/her consent, and the samples have 
already been tested, those results will still remain as part of the overall research data.
An informed consent, approved by an IRB/IEC, must be voluntarily signed and dated 
before samples are collected for optional exploratory research.  The nature of the testing 
should be explained and the subject given an opportunity to ask questions.  The informed 
consent must be signed before the samples are collected and any testing is performed.  If 
the subject does not consent to provide samples for the optional exploratory research, it 
will not impact their participation in the study.
In the event a subject withdraws from the main study, optional exploratory research
samples will continue to be stored and analyzed unless the subject specifically withdraws 
 

Venetoclax
M14-031 Protocol Amendment 8
EudraCT 2015-004411-20

consent for the optional samples.  If consent is withdrawn for the optional sampling, the 
subject must inform their study doctor, and once AbbVie is informed, the optional 
samples will be destroyed.  However, if the subject withdraws his/her consent and the 
samples have already been tested, those results will still remain as part of the overall 
research data.
9.3.1
Informed Consent Form and Explanatory Material
In Japan, the principal investigator will prepare the consent form and explanatory material 
required to obtain subject's consent to participate in the study with the cooperation of the

10.2
Case Report Forms
Case report forms (CRFs) must be completed for each subject screened/enrolled in this 
study.  These forms will be used to transmit information collected during the study to 
AbbVie and regulatory authorities, as applicable.  The CRF data for this study are being 
collected with an EDC system called Rave® provided by the technology vendor Medidata 
Solutions Incorporated, NY, USA.  The EDC system and the study-specific eCRFs will 
comply with Title 21 Code of Federal Regulations (CFR) Part 11.  The documentation 
related to the validation of the EDC system is available through the vendor, Medidata, 
while the validation of the study-specific eCRFs will be conducted by AbbVie and will be 
maintained in the Trial Master File at AbbVie.
The Investigator will document subject data in his/her own subject files.  These subject 
files will serve as source data for the study.  All eCRF data required by this protocol will 
be recorded by investigative site personnel in the EDC system.  All data entered into the 
eCRF will be supported by source documentation.
 

Venetoclax

Medidata will provide access to the EDC system for the duration of the trial through a 
password-protected method of internet access.  Such access will be removed from 
Investigator sites at the end of the site's participation in the study.  Data from the EDC 
system will be archived on appropriate data media (CD-ROM, etc.) and provided to the 
Investigator at that time as a durable record of the site's eCRF data.  It will be possible for 
the Investigator to make paper printouts from that media.
Patient-reported data must be completed for each subject enrolled in this study.  These 
data are being collected with an Electronic Patient Reported Outcome (ePRO) system 
called Trialmax, provided by the technology vendor Signant Health of Plymouth Meeting, 
PA, USA. The ePRO system is in compliance with Title 21 CFR Part 11.  The 
documentation related to the system validation of the ePRO system is available through 
the vendor, Signant Health, while the user acceptance testing of the study specific PRO 
design will be conducted and maintained at AbbVie.
The subject will be entering the data on an electronic device; the data will be uploaded to 
a server.  The data on the server will be considered source, and maintained and managed 
by Signant Health.
Internet access to the ePRO data will be provided by Signant Health for the duration of 
the study.  This access will be available for the duration of the study to the site 
investigator, as well as delegated personnel.  Such access will be removed from

regulatory inspection.
This confidential information shall remain the sole property of AbbVie, shall not be 
disclosed to others without the written consent of AbbVie, and shall not be used except in 
the performance of this study.
The Investigator will maintain a confidential subject identification code list of all subjects 
enrolled in the study, including each subject's name, subject number, address, phone 
number and emergency contact information.  This list will be maintained at the study site 
with other study records under adequate security and restricted access, and will not be 
retrieved by AbbVie.
Any research that may be done using research samples from this study will be 
experimental in nature and the results will not be suitable for clinical decision making or 
subject management.  Hence, the subject will not be informed of individual results, should 
analyses be performed, nor will anyone not directly involved in this research.  
Correspondingly, researchers will have no access to subject identifiers.  Individual results
will not be reported to anyone not directly involved in this research other than for 
regulatory purposes.  Data from research may be provided to investigators, used in 
scientific publications, or presented at medical conventions.  Research information will be 
published or presented only in a way that does not identify any individual subject.

The Investigator (Director of the Site in Japan) must retain any records related to the study 
according to local requirements.  If the Investigator (Director of the Site in Japan) is not 
able to retain the records, he/she must notify AbbVie to arrange alternative archiving 
options.
AbbVie will select the signatory coordinating Investigator from the Investigators who 
participate in each multi-center study.  Selection criteria for this signatory Investigator 
will be based on level of participation, and significant knowledge of the clinical research, 
investigational drug, and study protocol.  The signatory Investigator for the study will 
review and sign the final study report in accordance with the European Agency for the 
Evaluation of Medicinal Products (EMEA) Guidance on Investigator's Signature for Study 
Reports.
At the time the number of OS events required for the final OS analysis is reached, the end 
of study is defined as the date of the last subject's last Safety Follow-Up Visit.

Revised International Myeloma Working Group Diagnostic 
Criteria for Multiple Myeloma
Definition of Multiple Myeloma
Clonal bone marrow plasma cells ≥ 10% or biopsy-proven bony or extramedullary 
plasmacytoma* and any one or more of the following myeloma defining events:
Myeloma defining events:
1.
Evidence of end organ damage that can be attributed to the underlying plasma cell 
proliferative disorder, specifically:
●
Hypocalcaemia:  serum calcium > 0.25 mmol/L (> 1 mg/dL) higher than the 
upper limit of normal or > 2.75 mmol/L (>11 mg/dL)
●
Renal insufficiency:  creatinine clearance† < 40 mL per minute or serum 
creatinine > 177 μmol/L (> 2 mg/dL)
●
Anemia:  haemoglobin value of > 20 g/L below the lower limit of normal, or a 
haemoglobin value < 100 g/L
●
Bone lesions:  one or more osteolytic lesions on skeletal radiography, CT, or 
PET-CT‡
2.
Any one or more of the following biomarkers of malignancy:
●
Clonal bone marrow plasma cell percentage* ≥ 60%
●
Involved:uninvolved serum free light chain ratio§ ≥ 100
●
> 1 focal lesions¶ on MRI studies
PET-CT = 18F-fluorodeoxyglucose PET with CT
*
Clonality should be established by showing κ/λ-light-chain restriction on flow cytometry, immunohistochemistry, 
or immunofluorescence.  Bone marrow plasma cell percentage should preferably be estimated from a core biopsy 
specimen; in case of a disparity between the aspirate and core biopsy, the highest value should be used. 
†
Measured or estimated by validated equations.
‡
If bone marrow has less than 10% clonal plasma cells, more than one bone lesion is required to distinguish from 
solitary plasmacytoma with minimal marrow involvement.
§
These values are based on the serum Freelite assay (The Binding Site Group, Birmingham, UK).  The involved free 
light chain must be ≥ 100 mg/L.

dosing is held, dexamethasone should be administered as 
scheduled (unless interrupted due to toxicity).
Dexamethasone dosing (frequency and/or dose) may be 
reduced or discontinued per investigator's decision and 
institutional guidelines once subjects are unblinded.
When unblinding occurs, if subjects from Arm 1 (Venetoclax

disease at baseline was measurable on serum, urine, both, or neither) and

Disappearance of any soft tissue plasmacytomas and

< 5% plasma cells in bone marrowb and

Normal FLC (free light chain) ratio and

Absence of clonal cells in bone marrowb by immunohistochemistry or 
immunofluorescencec or 2 to 4 color flow cytometry
Complete response 
(CR)*

Negative immunofixation on the serum and urine (regardless of whether 
disease at baseline was measurable on serum, urine, both, or neither) and

Disappearance of any soft tissue plasmacytomas and

< 5% plasma cells in bone marrowb and

For subjects in whom the only measurable disease is by serum FLC 
levels, a normal FLC ratio** is also required.
Very good partial 
response (VGPR)*

Serum and urine M-component detectable by immunofixation but not on 
electrophoresis or

≥ 90% reduction in serum M-component plus urine M component 
< 100 mg per 24-hr 
For subjects in whom the only measurable disease is by serum FLC levels, 
VGPR is defined as:

≥ 90% decrease in the difference between involved and uninvolved FLC 
levels
Partial response (PR)

≥ 50% reduction of serum M-protein and

Reduction in 24-hr urinary M-protein by ≥ 90% or to < 200 mg per 
24-hr
o
If the serum and urine M-protein are unmeasurable,d a ≥ 50% 
decrease in the difference between involved and uninvolved FLC 
levels is required in place of the M-protein criteria.

≥ 50% reduction in the size of soft tissue plasmacytomas is also 
required, if present at baseline.

a.
All response categories require two consecutive assessments made at anytime before the institution of any new 
therapy; all categories also require no known evidence of progressive or new bone lesions if radiographic studies 
were performed.  Radiographic studies are not required to satisfy these response requirements.
b.
Confirmation with repeat bone marrow biopsy not needed.
c.
Presence/absence of clonal cells is based upon the k/λ ratio.  An abnormal k/λ ratio by immunohistochemistry, 
and/or flow cytometry and/or immunofluorescence requires a minimum of 100 plasma cells for analysis.  An 
abnormal ratio reflecting presence of an abnormal clone is k/λ of ≥ 4:1 or ≤ 1:2.
d.
Measurable disease for this study is defined as meeting at least one of the following three measurements:  Serum 
M-protein ≥ 0.5 g/dL (≥ 5 g/L) or Urine M-protein ≥ 200 mg/24 hr or serum FLC assay with an involved FLC level 
≥ 10 mg/dL (≥ 100 mg/L) provided serum FLC ratio is abnormal.
e.
Not recommended for use as an indicator of response; stability of disease is best described by providing the time to 
progression estimates.
Note:
* Clarification to IMWG criteria for coding CR and VGPR in subjects in whom the only measurable 
disease is by serum FLC levels:  CR in such subjects is defined as a normal FLC ratio of 0.26 – 1.65 in 
addition to CR criteria listed above.  VGPR in such subjects is defined as a > 90% decrease in the difference 
between involved and uninvolved free light chain FLC levels.
** Serum and urine M-protein testing is required to fulfill requirements of VGPR and CR categories 
regardless of whether disease at baseline was measurable on serum, urine, both, or neither.

Hypercalcemia > 11.5 mg/dL (> 2.875 mmol/L), and/or

Decrease in hemoglobin of ≥ 2 g/dL dL (≥ 1.25 mmol/L) or < 10 g/dL, 
and/or

Rise in serum creatinine by > 2 mg/dL (≥ 177 mmol/L), and/or

For progressive disease, serum M-component increases of ≥ 1 g/dL are sufficient to define relapse if starting 
M-component is ≥ 5 g/dL.
b.
For purposes of calculating time to progression and progression-free survival, CR subjects should also be evaluated 
using criteria listed above for progressive disease.
