SYNOPSIS
A Phase 2 Proof-of-Concept Study to Separately Evaluate the Activity of Talacotuzumab (JNJ-56022473) 
or Daratumumab in Transfusion-Dependent Subjects with Low or Intermediate-1 Risk Myelodysplastic 
Syndromes (MDS) who are Relapsed or Refractory to Erythropoiesis-Stimulating Agent (ESA) Treatment
Talacotuzumab (JNJ-56022473) is a humanized monoclonal antibody (mAb) that specifically targets the
human interleukin-3 receptor alpha chain (IL-3Ror CD123), and inhibits the signaling through this 
receptor.
Daratumumab is a human immunoglobulin G1 kappa (IgG1ĸ) mAb that binds with high affinity to a 
unique epitope on CD38, a transmembrane glycoprotein. 
Preclinical
and clinical
data indicate that
talacotuzumab and daratumumab may
eliminate
immunosuppressive cell types in the bone marrow microenvironment of patients with MDS. Elimination 
of MDSCs (by both compounds) and Tregs (daratumumab only) may alter the immunosuppressive 
microenvironment and allow normal hematopoietic progenitor cells to differentiate, and ultimately 
improve clinical outcomes. Elimination of CD123+ MDS blasts by talacotuzumab may further alter 
disease progression.
The purpose of this study is to separately evaluate 2 agents with different mechanisms of action that may 
be effective in subjects with low-risker MDS. The design of this study will allow an unbiased assessment 
of which agent, if either, will provide benefit to this patient population and further evaluate in clinical 
development. The generally accepted primary endpoint of transfusion independence (TI) has a subjective 
component based on transfusion practices that can be different across institutions, and randomizing 
subjects for talacotuzumab or daratumumab treatment with standardized inclusion and exclusion criteria 
and evaluation procedures will allow a more objective assessment of these 2 different agents.
OBJECTIVES, ENDPOINTS, AND HYPOTHESISES
Primary Objective
The primary objective of the study is to evaluate the efficacy (transfusion independence) of 
talacotuzumab (JNJ-56022473) or daratumumab in transfusion-dependent subjects with low or 
intermediate-1 risk MDS whose disease has relapsed during treatment with or is refractory to ESAs.
Primary Endpoint
The primary endpoint of this study is 8-week red blood cell (RBC) TI, defined as absence of RBC 
transfusion during any consecutive 56 days (8 weeks) post randomization.
Hypothesis
The primary hypothesis of this study is that the treatment with talacotuzumab or daratumumab separately 
will produce a TI rate 30% or greater against a minimal acceptable value of 15%. The statistical 
evaluation of the hypothesis will use a Bayesian approach to assess the likelihood of whether a true TI 
rate ≤15% can be ruled out.
OVERVIEW OF STUDY DESIGN
This is a multicenter, randomized, Phase 2, open-label study to evaluate the safety and efficacy of single-
agent talacotuzumab or single-agent daratumumab in subjects with low or intermediate-1 risk MDS who 
are transfusion-dependent and whose disease has relapsed during or is refractory to ESA treatment. 
Approximately 60 subjects (30 to receive talacotuzumab and 30 to receive daratumumab) will be enrolled

Clinical Protocol 56022473MDS2002 – Amendment 4

Status: Approved, Date: 13 December 2018
Randomization will be stratified based on transfusion burden (4 or >4 units) prior to randomization, and 
then assigned randomly on a 1:1 basis to receive either talacotuzumab or daratumumab. Enrollment to the 
talacotuzumab arm was closed (refer to Section 3.1 Overview of Study Design for details). Transfusion 
burden is defined as the maximum number of RBC units transfused over any 8 consecutive weeks during 
the 16 weeks prior to randomization. The study consists of: a Screening Phase of up to 28 days during 
which subject eligibility will be reviewed and approved by the sponsor prior to randomization, a 
Treatment Phase that will extend from the first dose on Cycle 1 Day 1 until study drug discontinuation, 
and a Posttreatment Follow-up Phase beginning once the subject discontinues talacotuzumab or 
daratumumab. 
Talacotuzumab will be administered at 9 mg/kg intravenously (IV) every 2 weeks. Daratumumab will be 
administered at 16 mg/kg IV weekly on Weeks 1 to 8, every 2 weeks for Weeks 9 to 24, and every 
4 weeks thereafter. Cycle length is a 28 days for both agents. Study drugs will continue to be administered 
until disease progression, lack of response, unacceptable toxicity, withdrawal of consent, or study end. 
The clinical cutoff for the purpose of the primary endpoint analysis will be 6 months after randomization 
of the last subject. The end of the study data collection is defined as either 1 year after the last subject has 
been randomized or anytime the sponsor terminates the study. At that time, study follow-up of subjects 
and study data collection will end. Subjects who are continuing to derive benefit from daratumumab 
treatment as assessed by their investigator may continue to receive daratumumab according to the 
protocol. During this period after study data collection has ended, only serious adverse events will be 
monitored and only entered into the company safety repository as described under Amendment 4 and in 
the Time and Events Schedule.
EVALUATIONS
Efficacy evaluations will include transfusion data, blood count assessments, and bone marrow biopsy and 
aspirate for disease assessment.
For all subjects in the talacotuzumab or daratumumab treatment groups, PK samples will be evaluated to 
determine serum concentration of talacotuzumab or daratumumab.
Serum concentrations of talacotuzumab or daratumumab and detection and characterization of anti-
talacotuzumab or anti-daratumumab antibodies will be performed.
Biomarker evaluations will include immunophenotyping of immune cell populations, enumeration of 
CD123 and CD38 expression on suppressor cells, reduction of blasts, mutation analysis, and proteomic 
analysis.Safety will be assessed by adverse events, physical examinations, clinical laboratory parameters, 
electrocardiograms, vital sign measurements, ECOG performance status, and concomitant medication 
usage. A sponsor safety review committee will review all the safety data on a quarterly basis, or ad hoc, 
as needed.
The follow-up of subjects in the study and study data collection will end either 1 year after the last subject 
is randomized or anytime the sponsor terminates the study. Subjects who are continuing to derive benefit 
from daratumumab treatment as assessed by their investigator may continue to receive daratumumab
according to the protocol. During this period after study data collection has ended, only serious adverse 
events will be monitored and only entered into the company safety repository as described under 
Amendment 4 and in the Time and Events Schedule.
STATISTICAL METHODS
There will be no formal statistical comparison between the 2 arms. Each treatment regimen will be 
analyzed separately to determine the likelihood that the true TI rate is 30% or greater against a minimum 
acceptable value of 15%. The planned sample size is approximately 30 subjects per treatment arm, which 
ensures at least 90% probability that the true TI rate is ≥15% if at least 8 subjects reach TI.

INTRODUCTION
The term “sponsor” used throughout this document refers to the entities listed in the Contact 
Information page(s), which will be provided as a separate document.
Myelodysplastic Syndromes
Myelodysplastic syndromes (MDS) are a heterogeneous group of malignant hematopoietic stem 
cell disorders that are characterized by cytopenias, myeloid dysplasia and a risk of 
transformation to acute myeloid leukemia.3 In MDS, an increase of inflammatory cells is 
observed in the bone marrow microenvironment, which may lead to suppression of normal 
differentiation of hematopoietic cells via recruitment of various immunosuppressor cell types. 
The immunosuppressive environment is also thought to induce tolerance of MDS blasts and 
allows further accumulation of genetic aberrations leading to disease progression.
The primary immunosuppressive cell types found in MDS are myeloid-derived suppressor cells 
(MDSCs), which are a key component in suppressing normal immune cell function. Upon 
stimulation, they cause a reduction in T-cell proliferation and IFNγ secretion2 and can inhibit NK 
cell function as well.11 When analyzing the secretome of MDSCs, high levels of suppressive 
cytokines IL-10 and TGF-β were expressed in vitro.2 Specifically in MDS, it has been shown by 
several groups that the frequency of MDSCs is increased in both the bone marrow and peripheral 
blood of patients with MDS compared to healthy controls.6 Interestingly, MDSCs were also 
shown to alter normal hematopoiesis through direct contact with hematopoietic stem and 
progenitor cells in vitro, which may contribute to anemia.2 Targeting these cells may improve 
anemias and lead to transfusion independence (TI) in MDS patients.
The standard prognostic tool in MDS is the International Prognostic Scoring System (IPSS),
which classifies patients into low, intermediate-1, intermediate-2, and high risk categories on the 
basis of the percentage of bone marrow blasts, the karyotype, and the number of cytopenias. The 
median survival rates for the low, intermediate-1, intermediate-2, and high risk categories are 
estimated at 5.7, 3.5, 1.2, and 0.4 years, respectively.3,7 Other prognostic systems have also been 
described, namely the WHO classification-based Prognostic Scoring System (WPSS)25 and 
IPSS-Revised (IPSS-R).8 The IPSS is more frequently referenced in clinical trials. Patients with 
low and intermediate-1 risk MDS are also often referred to as having “lower risk” disease, 
whereas those with intermediate-2 and high risk MDS are referred to as patients with “higher 
risk” disease.
Treatment Options for MDS 
For patients with IPSS low and intermediate-1 risk MDS, the initial approach to treatment 
typically involves supportive care measures, ie, red blood cell (RBC) transfusions or 
erythropoiesis-stimulating agents (ESAs) or other hematopoietic growth factors, aimed at 
alleviating cytopenias. Approximately 40% of the patients will achieve an International Working 
Group (IWG)-defined hematologic improvement to ESAs for a median duration of 2 years. The 
Nordic MDS group has developed a model that identifies patients more likely to respond to 
ESAs. Those with low or no transfusion requirements (<2 packed red blood cell [pRBC] 
units/month) and a low serum erythropoietin (EPO) level (<500 units/L) have a higher response

rate than those with high transfusion needs (≥2 units/month) and serum EPO
level
(≥500 units/L); 74% versus 7%, respectively.10
A marker of disease severity appears to be associated with early ESA failure (no response to 
ESA or relapse within 6 months). Patients whose disease fails ESA early compared to later 
failure have a higher rate of transformation to acute myeloid leukemia (AML) (5-year 
cumulative incidence of 22% versus 9%, respectively; p=0.02) with a much shorter median 
overall survival (OS) (37 months versus 54 months, respectively; p=0.02).15 This median 
survival is considerably shorter than predicted at the time of diagnosis.
For a small subset of patients with lower risk MDS that carry the del(5q) chromosomal 
abnormality, lenalidomide is approved by both the US Food and Drug Administration (FDA) and
European Medicines Agency (EMA) based on the data that shows approximately 60% of 
subjects achieving durable (>24 weeks) RBC TI. The median duration of response was 
approximately 2 years.
For the larger subset of patients, comprising about 90% of all lower risk MDS that does not have 
the del(5q) chromosomal abnormality, there is currently no universally accepted therapeutic 
option. Phase 2 and Phase 3 studies with lenalidomide have been conducted. Rates and durability 
of TI were lower than those observed in the cohorts with the del(5q) abnormality. Approximately 
one-quarter of patients (27%) who received lenalidomide achieved RBC TI, with median 
duration of response ranging from 33 to 41 weeks.20,21
Hypomethylating agents, approved for patients with higher-risk MDS, have been evaluated for
patients with lower risk MDS with multiple cytopenias after failure of other agents. In one study 
of decitabine given to 65 subjects with lower risk MDS, 23% achieved an overall improvement 
rate as assessed by modified IWG response of PR or better.5 In another study of 25 subjects, 44% 
achieved a CR or hematologic improvement (HI, IWG response).22 In this MDS patient 
population, a study with subcutaneous azacitidine resulted in a 23% response rate; and 17% of 
subjects who were RBC transfusion dependent at baseline became transfusion independent.24
Despite their efficacy, the hypomethylating agents are generally reserved for patients with higher 
risk MDS because of their myelosuppressive toxicity.
Most patients with IPSS low and intermediate-1 risk MDS who have failed to respond to ESAs
eventually require long-term RBC transfusions. Patients with low-risk MDS who are transfusion-
dependent, have limited treatment options and generally have poorer outcomes. Findings from a 
recent systematic literature review and meta-analysis reported a reduction in mortality in patients 
who were transfusion independent compared to those who were transfusion dependent.9 In 
addition, iron toxicity is an inevitable consequent of frequent red-blood-cell transfusions.19
Although data are preliminary regarding the role of MDSCs in MDS, experimental treatments 
with proposed mechanisms to treat the underlying pathophysiology of MDS and decrease 
dependence on transfusions and their resulting complications may be of benefit of patients in this 
population with a high unmet need for effective therapies.

1.1.
Study Drugs
Talacotuzumab (JNJ-56022473) is a humanized monoclonal antibody (mAb) that specifically 
targets the human interleukin-3 receptor alpha chain (IL-3Rα or CD123), and inhibits the 
signaling through this receptor. Talacotuzumab has been engineered to have increased affinity to 
human FcγRIIIa (CD16) expressed on NK cells and, as a consequence, has an enhanced ability 
to induce NK cell-mediated antibody-dependent cellular cytotoxicity (ADCC) against target cells
expressing CD123. In lower risk MDS, these cell types are primarily MDSCs and may include 
blasts. To date, one Phase 1 study (Study CSLCT-AML-11-73) has been completed for patients 
with AML in CR at high risk for relapse. This study established the dose and showed promising 
efficacy in small subset of patients with the primary mechanism of action being targeting CD123 
on AML blasts. In addition, an ongoing Phase 2/3 study (Study 56022473AML2002) is being 
conducted for patients older than 65 years with AML who are not candidates for intensive 
chemotherapy. In these studies, approximately 78 subjects have been treated with talacotuzumab 
as of 15 June 2016. Infusion-related reactions have been observed. These are generally mild to 
moderate, although Grade 3 events have been reported. Other potential risks include 
hypersensitivity (as part of an infusion-related reactions or alone), increased risk of infection, 
impaired response to live virus vaccinations, and immunogenicity to talacotuzumab.
Daratumumab (JNJ-54767414) is a human immunoglobulin G1 kappa (IgG1ĸ) mAb that binds 
with high affinity to a unique epitope on CD38, a transmembrane glycoprotein. It is a targeted 
immunotherapy directed towards tumor cells that express high levels of CD38, such as plasma 
cells from patients with multiple myeloma. Daratumumab was approved as monotherapy by the 
FDA and the EMA for the treatment of patients with relapsed and refractory multiple myeloma. 
Daratumumab is thought to mediate these responses, in part, through the elimination of CD38+
immunosuppressive cells (MDSCs, regulatory T cells [Tregs] and regulatory B cells [Bregs]) 
that synergizes with direct elimination of the myeloma cells.17 The identified risks associated 
with daratumumab include infusion-related reaction and interference with blood typing. 
Increased risk for infection is a potential risk, with upper respiratory tract infection (17%) the 
most frequent infection.

daratumumab, refer to the latest version of the respective Investigator’s Brochures and 
Addenda.12,13
1.2.
Overall Rationale for the Study
CD123 has been shown to be expressed on Lin- HLA-DRlow CD11b+ CD33+ MDSCs. Preliminary 
data demonstrated an increase in frequency of MDSCs in MDS patient samples compared to 
healthy controls (sponsor data on file).2 More importantly, the MDSCs in patients with MDS 
exhibit high levels of expression of CD123 (sponsor data on file). It is hypothesized that 
talacotuzumab will eliminate CD123+ MDSCs in patients with MDS through NK cell-mediated 
cytotoxicity, and promote effective hematological differentiation.
CD123 has also been regarded as a marker of leukemic stem cells (LSC), and overexpression of 
CD123 on LSCs has been shown to correlate to blast proliferation and poor prognosis in AML.23

Clinical Protocol 56022473MDS2002 – Amendment 4

Status: Approved, Date: 13 December 2018
Myelodysplastic syndromes, as a pre-leukemia status, are clonal disorders with enhanced risk of 
evolution towards AML,26 and it has been shown that CD123+ LSCs were increased in patients 
with MDS compared to healthy controls.27 Although the overall frequency of blasts in lower risk 
MDS is determined by having less than 5% blasts in the bone marrow, the CD123+ LSCs in 
MDS patients display similar malignant features observed in CD123+ LSCs in AML.18
Therefore, talacotuzumab may also eliminate CD123+ blasts in lower risk MDS patients and 
augment progression of disease.
Preliminary data on MDS patient samples has also shown high levels of expression of CD38 on 
MDSCs (sponsor data on file). In patients with multiple myeloma, MDSCs have been shown to 
express CD38, and are depleted after the first daratumumab infusion. More importantly, the 
MDSCs are sensitive and remain sensitive throughout daratumumab treatment.17 Therefore, it is 
also hypothesized that daratumumab will target CD38+ MDSCs in patients with MDS.
Lastly, Tregs have also been shown to be involved in the immunosuppressive microenvironment 
of low to intermediate 1-risk MDS patients.16 Univariate analysis of overall and progression-free 
survival of 38 low to intermediate 1-risk MDS patients showed that patients with increased 
numbers of Tregs (above the median) had a lower progression-free and OS than patients with 
less than median number of Tregs.14 In patients with multiple myeloma, CD38 has been shown 
to be expressed on a subset of Tregs, and the CD38+ subset of Tregs has been shown to be highly 
immunosuppressive of T cell activity compared to CD38- Tregs. Importantly, this highly 
immunosuppressive fraction of Tregs is targetable by daratumumab17 and therefore may also be 
a therapeutic target in patients with low-risk MDS. Reducing highly immunosuppressive CD38+
Tregs may alter the progression of disease.
These data indicate that talacotuzumab and daratumumab may eliminate immunosuppressive cell 
types in the bone marrow microenvironment of patients with MDS. Elimination of MDSCs (both 
compounds) and Tregs (daratumumab only) may alter the immunosuppressive microenvironment 
and allow normal hematopoietic progenitor cells to differentiate, and ultimately improve clinical 
outcomes. Lastly, elimination of CD123+ MDS blasts by talacotuzumab may further alter disease 
progression.

Hypothesis
The primary hypothesis of this study is that the treatment with talacotuzumab or daratumumab

STUDY DESIGN AND RATIONALE
3.1.
Overview of Study Design
This is a multicenter, randomized, Phase 2, open-label study to evaluate the safety and efficacy 
of single-agent talacotuzumab or single-agent daratumumab in subjects with low or 
intermediate-1 risk MDS who are transfusion-dependent and whose disease has relapsed during 
or is refractory to ESA treatment. Approximately 60 subjects (30 to receive talacotuzumab and 
30 to receive daratumumab) will be enrolled in this study. There will be no statistical hypothesis 
testing, and each arm will be assessed separately without formal comparison between the 2 arms. 
Statistical methods focus on the evaluation of the likelihood that either treatment regimen will 
result in a true TI rate of 30% or greater against a minimum acceptable value of 15%. The 
planned sample size is approximately 30 subjects per treatment arm, which will ensure at least 
90% probability that the true TI rate is greater than the minimum acceptable value 15% if at least 
8 subjects reach TI. A diagram of the study design is provided below in Figure 1.

Schematic Overview of the Study
Note: As a precautionary measure, due to benefit / risk considerations for patients with low-risk 
MDS, enrollment to the talacotuzumab arm is closed based upon the occurrence of a Grade 4
infusion-related reaction in the first subject to receive talacotuzumab. The IWRS was modified to 
only permit enrollment to the daratumumab arm of the study.
The end of study data collection is defined as either 1 year after the last subject is randomized or 
anytime the sponsor terminates the study. At that time, study follow-up of subjects and study 
data collection will end. Subjects who are continuing to derive benefit from daratumumab
treatment as assessed by their investigator may continue to receive daratumumab according to 
the protocol. During this period after study data collection has ended, only serious adverse events 
will be monitored and only entered into the company safety repository as described under 
Amendment 4 and in the Time and Events Schedule.

3.2.
Study Design Rationale
Inflammatory changes are a prominent feature in MDS with increased populations of
inflammatory cells in the bone marrow microenvironment. Inflammation in the bone marrow 
microenvironment leads to suppression of normal differentiation of hematopoietic cells via 
recruitment of suppressor cells. Myeloid-derived suppressor cells are thought to be a key 
component in suppressing normal immune cell function, and may have a profound role in the 
pathogenesis of MDS. The immunosuppressive environment is thought to promote tolerance to 
MDS blasts allowing accumulation of additional genetic aberrations. Targeting the inflammatory 
changes by eliminating either CD123- or CD38-expressing MDSCs may be a beneficial 
approach to the management of MDS.
Rationale for Randomization
Randomization will be used to allocate subjects to treatment groups. Although there is no formal 
statistical comparison between the 2 treatment groups, randomization can enhance the validity of 
statistical assessments to facilitate the decision making for further development of either or both 
treatment therapies if both treatment arms have met the primary objective. The primary endpoint 
of this study is defined by transfusion, and randomization can alleviate potential biases due to 
differences in transfusion practices across different sites and different countries. Enrollment to 
the talacotuzumab arm was closed (refer to Section 3.1 Overview of Study Design for details).
Rationale for Study Population 
Limited treatment options are available for patients who are RBC-transfusion dependent and who 
have IPSS low risk or intermediate-1 risk MDS that is relapsed/refractory to ESA treatment. An 
unmet need exists for agents that reduce the transfusion burden of these patients. The median 
survival for patients with low-risk MDS for whom ESA treatment has failed is about 3.5 years, 
which is considerably shorter than predicted at the time of diagnosis.4,15 Furthermore, emerging 
data describe the role of MDSCs as well as Tregs in the pathogenesis of MDS. Targeting CD123 
or CD38 on MDSCs with talacotuzumab or daratumumab, respectively, may show clinical 
benefit in patients with low-risk MDS.
Rationale for Endpoints
Transfusion independence for 8 weeks is a clinically meaningful and robust endpoint that is 
included in the IWG response criteria, and has been the basis for regulatory approvals.
The rate of HI-E will provide further explanation of the hematologic response (as per IWG 
criteria). Progression to AML and OS are important endpoints considering that the natural 
history of MDS progression includes transformation to AML in a proportion of patients. 
The depth of the response will be captured by assessment of CR and PR. Duration of responses 
will be assessed. Subjects will be followed for OS.

Dose Rationales for Talacotuzumab and Daratumumab
Dose Rationale for Talacotuzumab
The proposed 9 mg/kg every 2 weeks (q2w) dose was selected based on analysis of the PK, 
CD123 receptor occupancy (RO), pharmacodynamic (PD), and safety data generated in the 
Phase 1 study for patients with AML in CR at high risk for relapse (CSLCT-AML-11-73).
The 9 mg/kg q2w dose level has been selected as the talacotuzumab recommended Phase 2 dose
for patients with AML. It is the only dose level being tested in the ongoing Phase 2/3 study for 
talacotuzumab in patients older than 65 years with AML who are not candidates for intensive 
chemotherapy (Study 56022473AML2002).
Dose Rationale for Daratumumab
The dose and schedule used in this study (16 mg/kg weekly for 8 weeks, every 2 weeks for 
16 weeks, and every 4 weeks thereafter) is the approved dosing regimen of daratumumab for the 
treatment of subjects with relapsed and refractory multiple myeloma. This dose was selected
based on an acceptable safety profile, maximal clinical activity, and pharmacokinetics consistent 
with saturation of the target. This dose and similar schedules have been shown to be tolerable in 
several combination studies.

TREATMENT ALLOCATION AND BLINDING
5.1.
Treatment Allocation
Central randomization will be implemented in this study using an IWRS. Randomization will be 
stratified based on transfusion burden (4 or >4 units) prior to randomization, and then assigned 
randomly on a 1:1 basis to receive either talacotuzumab or daratumumab. Transfusion burden is 
defined as the maximum number of RBC units transfused over any 8 consecutive weeks during 
the 16 weeks prior to randomization. Enrollment to the talacotuzumab arm was closed (refer to 
Section 3.1 Overview of Study Design for details) and the IWRS was modified to only permit 
enrollment to the daratumumab arm of the study.
6.
DOSAGE AND ADMINISTRATION
Talacotuzumab and daratumumab are the investigational medicinal products in this study and 
will be provided by the sponsor.
Subjects may receive treatment until disease progression, lack of response, unacceptable toxicity, 
withdrawal of consent, or study end. Continuation of treatment for subjects who are not deriving 
benefit, ie, after 6 months of treatment a subject has not achieved HI-E or RBC TI for ≥8 weeks, 
should be discussed with the sponsor.
Supportive Care
All subjects will receive supportive care (including transfusions if Hb ≤11 g/dL or myeloid 
growth factors) as needed per investigator discretion and according to local standard practices. 
Should an exceptional situation arise where it is deemed clinically necessary to give a transfusion 
for an Hb >11 g/dL, the sponsor should be notified.

window of ±3 days is allowed for Day 1 of each cycle visits to the clinic. Each cycle is 28 days. 
The first visit of a cycle should be 4 weeks after the start of the previous cycle. The start of each 
cycle may occur ±3 days of the scheduled day in order to accommodate the schedule of the site 
or subject. Day 1 of subsequent cycles should be adjusted accordingly to maintain the 28-day 
cycle duration

Talacotuzumab 9
mg/kg will be administered on Days 1 and 15 for all cycles.
Daratumumab 16 mg/kg will be administered on Days 1, 8, 15, and 22 (+/- 24 hours) for Cycles 
1 and 2; on Days 1 and 15 (+/- 24 hours) for Cycles 3 to 6; and on Day 1 (+/- 24 hours) for all 
subsequent cycles. Cycles may be delayed due to drug-related toxicities (See Sections 6.2.3 and 
6.3.5). 
The follow-up of subjects in the study and study data collection will end either 1 year after the 
last subject is randomized or anytime the sponsor terminates the study. Subjects who are 
continuing to derive benefit from daratumumab treatment as assessed by their investigator may 
continue to receive daratumumab according to the protocol. During this period after study data 
collection has ended, only serious adverse events will be monitored and only entered into the 
company safety repository as described under Amendment 4 and in the Time and Events 
Schedule.
6.2.
Talacotuzumab
6.2.1.
Preparation and Administration of Talacotuzumab
Talacotuzumab will be supplied as a lyophilized product containing 100 mg of active 
pharmaceutical ingredient (50 mg/mL after reconstitution with 2.0 mL sterile water for 
injection). 
The talacotuzumab dose administered will be dependent upon the subject’s weight at the Day 1 
assessment of each cycle. The talacotuzumab dose should be adjusted in case the subject’s 
weight changes by >10%. Talacotuzumab will be administered as a 250 mL IV infusion over 
approximately 180 minutes using an infusion pump. The talacotuzumab treatment will be 
administered per the dosing schedule described in Section 6.1. If an infusion-related reaction is 
observed during the administration of talacotuzumab, then follow the procedures described in 
Section 6.2.4. The sponsor may modify the infusion rates or the preinfusion medications 
prospectively based upon the information collected to date from this and other studies. 
Additional details for administration times and rates, as well as preinfusion medications, will be 
provided in the administration guidelines (study site investigational product and procedures 
manual).
Subjects should be carefully observed during talacotuzumab infusions. Trained study staff at the 
clinic should be prepared to intervene in case any infusion reactions occur. Resuscitation 
equipment and other agents necessary to treat anaphylaxis must be readily available (eg, 
NCT03011034

epinephrine, corticosteroids, intravenous antihistamines, bronchodilators, oxygen). Attention to 
staffing should be considered when multiple subjects will be dosed at the same time.
The rate of the talacotuzumab infusion is as follows:
First Three Cycles: Initiate the IV infusion at a rate of 20 mL/hr. In the absence of any infusion-
related reaction during the first 30 minutes, increase the infusion rate to 40 mL/hr for 30 minutes.
If no infusion reaction is observed during this 30 minute period, increase the infusion rate by 40 
mL/hr increments every 30 minutes. The infusion rate should not exceed 150 mL/hr at any time. 
Subjects should be monitored for infusion reactions for 1 hour after completion of the 
talacotuzumab infusion.
Subsequent Cycles (after the first 3 cycles): If no infusion reaction observed in the first 3 
cycles, initiate the IV infusion at a rate of 40 mL/hr for 30 minutes. If no infusion-related 
reactions are observed during this period, increase the infusion rate by 40 mL/hr every 30 
minutes. The infusion rate should not exceed 150 mL/hr at any time. Subjects should be 
monitored for infusion reactions for 1 hour after completion of the talacotuzumab infusion.
6.2.2.
Talacotuzumab: Premedication 
All subjects receiving talacotuzumab must receive premedication during the first 4 cycles, as 
outlined in Table 1. If no infusion-related reactions are seen during the first 4 cycles of 
talacotuzumab treatment, then premedication is optional for subsequent talacotuzumab
treatments. If an infusion-related reaction of any severity occurs in subsequent talacotuzumab
treatments, premedication must be reintroduced.

6.2.3.
Talacotuzumab Dosing Modifications
Refer to Section 6.2.4 for details on management of infusion-related reactions. 
Dose delay is the primary method for managing talacotuzumab-related toxicities. 
A dose delay should occur if any of the following criteria are met:

Febrile neutropenia;

Grade 3 or higher hemorrhagic event;

Toxicity that in the opinion of the investigator requires delay.
If the dose of talacotuzumab is delayed by more than 3 days, then the dose should be skipped. 
Administration may resume at the next planned dosing date. A missed dose will not be made up.
If there is more than a 28-day delay between doses, then the subject may only be allowed to 
continue treatment if the investigator and sponsor believe it is in the best interest of the subject. 
However, this must be approved by the sponsor.
6.2.4.
Management of Talacotuzumab Hypersensitivity/Infusion-related
Reactions
Subjects should be carefully observed during infusions. It is recommended that subjects are 
monitored for at least 1 hour after the infusion has been completed.
Subjects who experience treatment-emergent adverse events during the IV infusion of 
talacotuzumab will be treated according to the investigator’s judgment and best clinical practice. 
It is suggested that standing orders are readily available so that timely treatment can be provided 
to patients who experience infusion-related reactions. The following guidelines are suggestions 
for how reactions may be managed:

Subjects should be treated with acetaminophen, H1-antihistamine, or corticosteroids.
Intravenous saline may be indicated. For bronchospasm, urticaria, or dyspnea, subjects may
require H1-antihistamines, oxygen, corticosteroids, or bronchodilators. For hypotension,
subjects may require vasopressors.

In the event of a life-threatening infusion-related reaction (which may include pulmonary or
cardiac events), or anaphylactic reaction, talacotuzumab should be permanently discontinued 
and no additional talacotuzumab should be administered to the subject. 
6.2.4.1.
Guidelines for the Interruption of Talacotuzumab Infusion due to 
Infusion-related Reaction
If an infusion-related reaction develops, then the infusion should be temporarily interrupted and 
the actions in Table 2 should be taken.


If the investigator assesses a TEAE to be related to the talacotuzumab, 
pause infusion

When the subject’s condition is stable, the infusion may be restarted at 
the investigator’s discretion. The infusion rate should be at half the 
previous rate

Subsequently, the infusion rate may be increased at the 
investigator’s discretion but should not exceed 150 mL/hr at any 
time

If the subject experiences a Grade 2 or higher event of laryngeal edema 
or a Grade 2 or higher event of bronchospasm that does not respond to 
systemic therapy and does not resolve within 6 hours from the onset, 
then the subject must be withdrawn from treatment
Grade 3

For infusion-related TEAEs that are Grade 3, stop infusion

Observe subject carefully until resolution of the TEAE or until the 
severity of the event decreases to Grade 1 or baseline, at which point the 
infusion may be restarted at the investigator’s discretion. Upon restart, 
the infusion rate should be half of that used before the interruption. 
Subsequently, the infusion rate may be increased at the investigator’s 
discretion but should not exceed 150 mL/hr at any time.

If the severity of the TEAE returns to Grade 3 after restart of the 
infusion, then the procedure described in this section may be 
repeated at the investigator’s discretion.

Daratumumab
6.3.1.
Dosing Schedule
Details of the procedures performed during the Treatment Phase are outlined in the Time and 
Events Schedules. Subjects should start study treatment within 72 hours after randomization. A 
window of ±3 days is allowed for Day 1 of each cycle visits to the clinic. Each cycle is 28 days. 
The first visit of a cycle should be 4 weeks after the start of the previous cycle. The start of each 
cycle may occur ±3 days of the scheduled day in order to accommodate the schedule of the site 
or subject. Day 1 of subsequent cycles should be adjusted accordingly to maintain the 28-day 
cycle duration. In Cycles 1 through 6, weekly or bi-weekly daratumumab infusions may be given 
within ±1 day of the scheduled day in order to accommodate the schedule of the site or subject.
6.3.2.
Preparation and Administration of Daratumumab
The infusion solution will be prepared as a 1,000-mL (first dose) or 500-mL (second and 
subsequent doses) dilution of daratumumab in sterile, pyrogen-free 0.9% NaCl. Preparation of 
infusion bags should be done on the day of the planned infusion. Daratumumab must be 
administered as an IV infusion given through a well-functioning IV catheter by using an infusion 
pump. The study drug must be filtered by using an inline filter (0.2 μM) during the infusion. 
Manuals with detailed descriptions for preparation and administration of daratumumab will be 
supplied to each pharmacy and site.

Status: Approved, Date: 13 December 2018
The daratumumab dose administered will be calculated based on the subject’s weight at Cycle 1 
Day 1 rounded to the nearest kilogram. The dose of daratumumab will remain constant 
throughout the study, unless the subject’s weight changes more than 10% from Cycle 1 Day 1. 
All infusions will be planned as outpatient visits. The daratumumab treatment will be 
administered per the dosing schedule described in Section 6.1.
The dilution volumes, initial infusion rates, and increment of infusion rates for the first, second, 
and subsequent doses in the absence of an infusion-related reaction >Grade 1 are provided 
in Table 3. The first infusion, with a volume of 1,000 mL, takes approximately 8 hours; the 
second and subsequent infusions, with volumes of 500 mL, take approximately 4 hours. The 
maximum infusion rate for all infusions is 200 mL/hour. The sponsor may modify the infusion 
rates or the preinfusion medications prospectively based upon the information collected to date 
from this and other studies. Additional details for administration times and rates, as well as
preinfusion medications, will be provided in the administration guidelines (study site

As noted in the Time and Events Schedule, vital signs should be monitored extensively on 
Cycle 1 Day 1 before, during, and after the first infusion of daratumumab. For all other infusions, 
vital signs should be measured before the start of the infusion and at the end of the infusion. If a 
subject experiences any significant medical event, then the investigator should assess whether 
the subject should stay overnight for observation. If the subject has not experienced a significant 
medical event but is hospitalized overnight only for observation, then the hospitalization should 
not be reported as a serious adverse event.

Postinfusion medication should be administered to reduce the risk of delayed infusion reactions 
in all subjects who receive daratumumab:

Oral corticosteroid (20 mg methylprednisolone or equivalent) on the first and second day 
after all infusions (if no infusion-related reaction is observed after the first 3 infusions, then 
postinfusion corticosteroids should be administered per investigator discretion)
For subjects with a higher risk of respiratory complications (eg, subjects with mild asthma or 
subjects with COPD) the following postinfusion medications should be considered:

Antihistamine (diphenhydramine or equivalent) 

Leukotriene inhibitor (montelukast or equivalent)

Short-acting β2 adrenergic receptor agonist such as salbutamol aerosol 


In addition, these at-risk subjects may be hospitalized for monitoring for up to 2 nights after an 
infusion. If subjects are hospitalized, then their spirometry test (FEV1) should be performed 
before discharge. If these subjects are not hospitalized, then a follow-up telephone call should be 
made to monitor their condition within 48 hours after all infusions. If no infusion-related reaction 
has occurred, the follow-up telephone call 48 hours after the infusion is not required. If the 
subject has not experienced a significant medical event but is hospitalized overnight only for 
observation, then the hospitalization should not be reported as a serious adverse event.
Investigators may prescribe bronchodilators, H1-antihistamines, and corticosteroids that are 
deemed necessary to provide adequate supportive care in the event a bronchospasm occurs after 
subjects are released from the hospital/clinic. If an at-risk subject experiences no major infusion-
related reactions, then these postinfusion medications may be waived after 4 doses at the 
investigator’s discretion. 
Any postinfusion medication will be administered after the infusion has completed.
Refer to Section 6.3.6 for additional details on the management of infusion reactions. 
6.3.4.
Daratumumab Dosing Delay and Modification
Dose modification of daratumumab is not permitted. Dose delay is the primary method for 
managing daratumumab-related toxicities.
6.3.5.
Daratumumab Toxicity Management
Cycle Delays
On the first day of each new treatment cycle and before each daratumumab dose, the subject will 
be evaluated by the treating physician for possible toxicities that may have occurred after the 
previous dose(s). Toxicities are to be assessed according to NCI-CTCAE, Version 4.03. Dose 
delays will be based on the toxicity experienced during the previous infusion or newly 
encountered on Day 1 of a new cycle. 
To allow for recovery from toxicity, the study treatment must be held if any of the following 
criteria are met, regardless of relationship to daratumumab.

Grade 4 hematologic toxicity, except for Grade 4 lymphopenia

Grade 3 or thrombocytopenia with (any grade) bleeding 

Febrile neutropenia

Neutropenia with infection, of any grade

Grade 3 or higher non-hematologic toxicities with the following exceptions: 

Grade 3 nausea that responds to antiemetic treatment within 7 days

Grade 3 vomiting that responds to antiemetic treatment within 7 days


Doses of daratumumab may be delayed up to 4 weeks (Cycle 1 to Cycle 6) or up to 6 weeks 
(Cycle 7 and beyond). If Day 1 of a cycle is delayed, Day 1 of subsequent cycles should be 
adjusted accordingly to maintain the 28-day cycle duration. However, if a within-cycle dose is 
delayed, then the dates of the subsequent within-cycle doses should not be adjusted. Any adverse 
event deemed to be related to daratumumab that requires a dose hold of more than 4 weeks 
(Cycle 1 to Cycle 6) or more than 6 weeks (Cycle 7 and beyond) will result in permanent 
discontinuation of daratumumab. If a dose delay occurs, then pharmacokinetic and 
pharmacodynamic assessments should be performed on the actual administration day of 
daratumumab, not on the original scheduled administration day.
A daratumumab dose that is held for more than the permitted time (Table 5) from the per-
protocol administration date for any reason other than toxicities suspected to be related to 
daratumumab should be brought to the attention of the sponsor at the earliest possible time. 
Subjects whose dose was delayed for more than 4 weeks (Cycle 1 to Cycle 6) or more than 
6 weeks (Cycle 7 and beyond) should have study treatment discontinued, unless, upon 
consultation with the sponsor and the review of safety and efficacy, continuation is agreed upon.
6.3.6.
Guidelines for Daratumumab Infusion-Related Reactions
Subjects should be carefully observed during infusions.
Trained study staff at the clinic should be prepared to intervene in case of any infusion reactions,
and resources necessary for resuscitation must be available. Attention to staffing should be 
considered when multiple subjects will be dosed at the same time.

PRESTUDY AND CONCOMITANT THERAPY
8.1.
Prestudy Therapy
Prestudy MDS therapies administered up to 30 days before first dose of study drug must be 
recorded at screening. Transfusions up to 16 weeks prior to randomization also must be recorded 
at screening.
8.2.
Concomitant Medications
Subjects should receive supportive care as clinically indicated. This includes blood product 
support (blood transfusions and use of granulocyte colony stimulating growth factors), anti-
diarrheals, anti-emetics, analgesics, anti-infective treatment, and treatment of other medical 
conditions.
The following medications are prohibited during the study: ESA therapy, chemotherapy 
(anticancer), immunomodulatory drugs, immunotherapy, experimental therapy, and radiotherapy. 
Systemic use of corticosteroids in excess of prednisone 20 mg/day or its equivalent for more than

10 days is prohibited unless reviewed and approved by the sponsor. Long-term, chronic use of 
corticosteroids at any dose should also be reviewed and approved by the sponsor. Corticosteroids 
used as premedication are permitted. The sponsor must be notified in advance (or as soon as 
possible thereafter) of any instances in which prohibited therapies are administered.
All concomitant therapies (prescription or over-the-counter medications, including vaccines, 
vitamins, herbal supplements), including growth factors, transfusions, anti-infectives 
(antibacterials, antivirals, and antimycotics), corticosteroids, anti-arrhythmics and other cardiac 
supportive therapy, anti-histamines, anti-emetics, anti-diarrheals, and anti-coagulants must be 
recorded throughout the study beginning with signing of the ICF to 30 days after the end of 
dosing or until the start of subsequent anticancer treatment, if earlier. Modification of an 
effective preexisting therapy should not be made for the explicit purpose of entering a subject 
into the study. Concomitant therapies should be recorded beyond 30 days after the last dose of 
study treatment only in conjunction with new or worsening adverse events or serious adverse 
events that meet the criteria outlined in Section 12.3.2, Serious Adverse Events. The follow-up of 
subjects in the study and study data collection will end either 1 year after the last subject is 
randomized or anytime the sponsor terminates the study. Subjects who are continuing to derive 
benefit from daratumumab treatment as assessed by their investigator may continue to receive 
daratumumab according to the protocol. During this period after study data collection has ended, 
only serious adverse events will be monitored and only entered into the company safety 
repository as described under Amendment 4 and in the Time and Events Schedule.

STUDY EVALUATIONS
The follow-up of subjects in the study and study data collection will end either 1 year after the 
last subject is randomized or anytime the sponsor terminates the study. Subjects who are 
continuing to derive benefit from daratumumab treatment as assessed by their investigator may 
continue to receive daratumumab according to the protocol. During this period after study data 
collection has ended, only serious adverse events will be monitored and only entered into the

Study Procedures
9.1.1.
Overview
The Time and Events Schedule summarize the frequency and timing of efficacy, PK, 
immunogenicity, biomarker, and safety measurements applicable to this study.
If multiple assessments are scheduled for the same timepoint, it is recommended that procedures 
be performed in the following sequence: ECG, vital signs/physical exam, bone marrow 
assessments/clinical laboratory assessments/peripheral blood sampling for central lab 
submission, response assessment and other subject review data collection, study drug 
administration. Blood collections for PK assessments should be kept as close to the specified 
time as possible. Other measurements may be done earlier than specified timepoints if needed. 
Actual dates and times of assessments will be recorded in the source documentation and eCRF.

Status: Approved, Date: 13 December 2018
The total blood volume to be collected from each subject will be approximately 330 mL for 
subjects completing 8 cycles. Repeat or unscheduled samples may be taken for safety reasons or 
for technical issues with the samples.
An indwelling intravenous cannula may be used for blood sample collection. If a mandarin 
(obturator) is used, blood loss due to discard is not expected.
Additional serum or urine pregnancy tests may be performed, as determined necessary by the 
investigator or required by local regulation, to establish the absence of pregnancy at any time 
during the subject's participation in the study. Repeat or unscheduled samples may be taken for 
safety reasons or technical issues with the samples.
9.1.2.
Screening Phase
Screening procedures will be performed within 28 days before randomization, as described in the 
Time and Events Schedules.
9.1.3.
Open-Label Treatment Phase
The Treatment Phase will begin on Day 1 of Cycle 1 and will continue until discontinuation of 
study drug.
Treatment Phase
A treatment cycle is defined as 28 days. Details of the procedures performed during the 
Treatment Phase are outlined in the Time and Events Schedules. Subjects will be monitored for 
adverse events, laboratory abnormalities, hematologic improvement, reduction in transfusion 
requirement, and clinical response. All Treatment Phase visit procedures are to be performed
predose, unless otherwise specified, and laboratory test results must be reviewed prior to 
administering study drug. Adverse events and changes to concomitant medications will be 
recorded. The investigator will assess subject response to therapy using the efficacy 
measurements and disease response criteria according to the IWG 2006 (Attachment 6). If a 
subject develops features of response (eg, recovery from all cytopenias) and CR or PR are 
clinically suspected at a time not specified on the Time and Events Schedules, then all required 
disease assessments should be performed. In order to confirm a CR or PR per IWG 2006 criteria, 
all disease assessments including bone marrow aspirate should be repeated 4-8 weeks from time 
of CR or PR. If progressive disease is diagnosed, or the subject discontinues study drug for other 
reasons, then the subject will complete the End-of-Treatment Visit within 30 days after the last 
dose of study drug, and enter the Posttreatment Follow-up Phase. 
End of Treatment/Early Withdrawal
An End-of-Treatment Visit will be scheduled within 30 days after the last dose of study drug for 
all subjects, including those who discontinued study drug for any reason, except for those lost to 
follow-up, death, or withdrawal of consent for study participation. Subjects who discontinued 
study drug due to disease progression, adverse event, lack of response, or other reasons and enter 
the Posttreatment Follow-up Phase should have the End-of-Treatment Visit completed before 
starting any subsequent MDS treatment. If a subject is unable to return to the site for the End-of-

Treatment Visit, then the subject should be contacted to collect adverse events that occur within 
30 days after the last dose of the last study drug. Additional information on reporting adverse 
events may be found in Section 12.3.1. 
9.1.4.
Posttreatment Phase (Follow-Up)
The Posttreatment Follow-up Phase is the time between the End-of-Treatment Visit and the end 
of study participation or end of study. Subjects who are continuing to derive benefit from 
treatment as assessed by their investigator will continue to receive treatment and be monitored 
for safety by the sponsor.
During this phase, contact will be made as detailed in the Time and Events Schedules every 
16 weeks. 
If the information on survival status and subsequent therapy is obtained via telephone contact, 
then written documentation of the communication must be available for review in the source 
documents. If the subject has died, then the date and cause of death will be collected and 
documented on the eCRF. Where allowed by local law, public records may be used to document 
death for the purpose of obtaining survival status.
9.1.5.
Clinical Cutoff and End of Study
The clinical cutoff for the purpose of primary endpoint analysis is 6 months after randomization 
of the last subject. 
The end of study data collection is defined as either 1 year after the last subject is randomized or 
anytime the sponsor terminates the study. At that time, study follow-up of subjects and study 
data collection will end. Subjects who are continuing to derive benefit from daratumumab 
treatment as assessed by their investigator may continue to receive daratumumab according to 
the protocol. During this period after study data collection has ended, only serious adverse events 
will be monitored and only entered into the company safety repository as described under 
Amendment 4 and in the Time and Events Schedule.
9.2.
Efficacy Evaluations
Efficacy evaluations will include transfusion data, blood count assessments, and bone marrow 
biopsy and aspirate for disease assessment.
9.2.1.
Transfusions
Data to be collected at each visit include the number of units and type of blood products 
transfused and the pre-transfusion hemoglobin and platelet count. Transfusion data will be 
collected during the treatment and posttreatment periods as specified in the Time and Event 
Schedules. Transfusion is monitored at each visit for infusion (every 4-week cycle), at each 
disease evaluation visit, and at all unscheduled visits during treatment. During the posttreatment 
phase, transfusion data will be collected every 4 to 6 weeks. Specific operational monitoring will 
be implemented to seek transfusion information from other documented sources. Specific and 
continuous medical review will be implemented to identify any sudden but unsustained increase

of Hb values and to query whether transfusion has occurred. Red blood cell transfusions may be 
administered based on hemoglobin level (sponsor should be notified for Hb >11 g/dL), 
investigator’s assessment of the subject’s clinical signs and symptoms, and local clinical 
practice.
As the volume of 1 unit of RBC transfusion may vary regionally, 1 unit is defined as the amount 
that is intended to raise Hb by approximately 1 g/dL in an adult patient (ie, 1 standard pRBC unit 
or equivalent). The total number of RBC units required over consecutive 8-week time periods 
will be calculated to identify subjects who achieve RBC TI or transfusion reduction.
9.2.2.
Hemoglobin Assessment
Hemoglobin levels will be measured weekly during the first 8 weeks, at the start of each cycle, 
and as clinically needed.
For a given subject, the same local laboratory should be used for each hematology assessment 
throughout the study, to the extent possible. Hematologic improvement-erythroid response 
(HI-E) is defined as a Hb rise of at least 1.5 g/dL above baseline, measured 28 days or more 
following the last RBC transfusion or reduction of at least 4 units of RBC transfusions/8 weeks 
compared with the 8 weeks prior to start of treatment (criterion adapted from IWG 2006).
9.2.3.
Clinical Bone Marrow Assesment 
Bone marrow aspirate and biopsy must be performed during screening or up to 12 weeks before 
randomization. Follow-up bone marrow exams will be performed every 24 weeks, at the time of 
PR and CR (as indicated by peripheral blood counts), at disease progression, and at end-of-
treatment. Following the bone marrow exams at PR and CR, bone marrow sampling should be 
repeated 4 to 8 weeks later. Bone marrow sampling does not have to be repeated at the End-of-
Treatment visit if the prior assessment occurred within 8 weeks.

Pharmacokinetics and Immunogenicity
9.3.1.
Sample Collection and Handling
For all subjects in the talacotuzumab or daratumumab treatment groups, PK samples to 
determine serum concentration of talacotuzumab or daratumumab will be obtained according to 
the Time and Events Schedules. 
Venous blood samples (5 mL per sample) will be collected to determine serum concentration of 
talacotuzumab or daratumumab. The serum will be divided into 3 aliquots: 1 aliquot for PK 
analyses for talacotuzumab or daratumumab, 1 aliquot for anti-talacotuzumab or anti-
daratumumab antibodies assessment (when appropriate), and 1 aliquot as a backup. Samples 
collected for determining serum concentrations of talacotuzumab or daratumumab in this study 
may be used to address questions about drug characteristics that may arise at a later time point, 
or evaluation of safety or efficacy aspects that address concerns arising during or after the study 
period. In addition, samples will be collected at the time of an infusion-related reaction. Genetic 
analyses will not be performed on these samples.

Status: Approved, Date: 13 December 2018
The exact dates and times of blood sampling must be recorded. Refer to the laboratory manual or 
equivalent document for sample collection requirements. Collected samples must be stored under 
the specified and controlled conditions for the temperatures indicated in the laboratory manual.
9.3.2.
Analytical Procedures
Pharmacokinetics/Immunogenicity
Serum concentrations of talacotuzumab or daratumumab and detection and characterization of 
anti-talacotuzumab or anti-daratumumab antibodies will be performed using validated 
immunoassay methods by or under the supervision of the sponsor. 
9.3.3.
Pharmacokinetic Parameters 
Serum concentrations of talacotuzumab or daratumumab will be measured and resulting 
concentration over time data will be summarized by treatment. Population PK models may be 
explored and developed if data are sufficient from this study and may include data from other 
studies. 
The PK parameters are defined as:
If sufficient data are available, then pharmacokinetic/pharmacodynamics (PK/PD) modeling may 
be performed, including exploring the relationship between serum concentrations of 
talacotuzumab or daratumumab and biomarkers, PD markers, and endpoints of clinical efficacy,
and may include data from other studies. If these analyses are performed, the details and results 
will be presented in a separate report. 
9.3.4.
Immunogenicity Assessments (Antibodies to Talacotuzumab and 
Daratumumab)
Serum from venous blood samples collected from all subjects will be assessed for the generation 
of antibodies to talacotuzumab or daratumumab (immunogenicity) according to Time and Events 
Schedules. Talacotuzumab
or daratumumab concentration will be evaluated at all 
immunogenicity time points to ensure appropriate interpretation of immunogenicity data. When 
both serum concentration and immunogenicity analyses are specified for a particular timepoint, 
they are performed on aliquots from the same blood draw and no additional sampling is required. 
Procedures for sample collection, preparation, identification, storage, and shipment will be 
provided in the laboratory manual or equivalent document.
Additionally, blood samples to assess immunogenicity of either talacotuzumab or daratumumab 
should be collected at the final visit for subjects who discontinue treatment. Subjects who 
discontinue treatment will also be asked to return for immunogenicity evaluation during the 
Follow-up Phase.

Status: Approved, Date: 13 December 2018
Serum samples will be screened for antibodies binding to talacotuzumab or daratumumab and 
serum titer will also be determined from confirmed positive samples using validated assay 
methods by or under the supervision of the sponsor. Other immunogenicity analyses 
(eg, assessment of neutralizing capabilities) may be performed to further characterize the 
immune responses that are generated. 
A blood sample should be drawn, if possible, for determination of antibodies to talacotuzumab 
any time an infusion-related reaction is observed or reported during the study. Serum 
concentration will also be determined from the same infusion-related reaction sample for the 
purpose of interpreting immunogenicity data. These samples will be stored and evaluated if 
deemed necessary. If the infusion-related reaction results in treatment discontinuation, then 
subjects should undergo all scheduled safety and efficacy evaluations. Samples collected for the 
analysis of talacotuzumab or daratumumab immunogenicity/serum concentration may 
additionally be used to evaluate safety or efficacy aspects that address concerns arising during or 
after the study period or for the evaluation of relevant biomarkers by the sponsor or sponsor’s 
designee.
9.4.
Biomarkers 
Biomarker analyses are dependent upon the availability of appropriate biomarker assays and may 
be deferred or not performed if, during or at the end of the study, it becomes clear that the 
analysis will have no scientific value, or if there are not enough samples or not enough 
responders to allow for adequate biomarker evaluation. In the event the study is terminated early 
or shows poor clinical efficacy, completion of biomarker assessments is based on justification 
and intended utility of the data. Samples for biomarker evaluations will be collected as specified 
in the Time and Events Schedules and will be analyzed at a central laboratory.
Assessment of Pharmacodynamic Markers (Basophils and pDC)
Previous clinical studies with talacotuzumab in patients with AML demonstrated that pDCs and 
basophils are reliable cellular PD markers for talacotuzumab activity, and that NK cells and 
monocytes are relatively stable in number from baseline during the treatment. Changes of cell 
numbers of cellular biomarkers (basophils, pDC, monocytes, eosinophils and NK cells) will be 
enumerated in the peripheral blood by flow cytometry.
Determination of CD123 and CD38 Expression 
CD123 expression in various cell populations at baseline (bone marrow aspirate) will be 
determined by flow cytometry of MDSCs and MDS blasts, and CD38 expression will be 
analyzed in MDSCs and Tregs. CD123 expression of various cell populations listed above will 
also be analyzed in the peripheral blood and bone marrow throughout the study (see Time and 
Events Schedules). The diagnostic block for each patient will be requested to evaluate CD123 
expression by immunohistochemistry (IHC) at a central laboratory. Upon disease progression, 
MDSCs (CD123 and CD38), blasts (CD123), and Tregs (CD38) will be evaluated.

Status: Approved, Date: 13 December 2018
Mutation Analysis
Some somatic mutations are known to confer a poor prognosis and resistance to certain forms of 
therapy. Therefore, baseline mutation status will be evaluated in the baseline bone marrow 
biopsy to explore potential inter-individual variability in clinical outcomes or identification of 
population subgroups that respond differently to either treatment.
Immunophenotyping and Calculating Baseline Frequencies
Whole blood will be utilized for immunophenotyping (performed by flow cytometry or mass 
cytometry/CyTOF), which includes analyses of NK cells, MDSCs, MDS blasts, and T cells as 
well as other potential immune cell subpopulations and their absolute numbers. The NK cells 
(CD45+CD56+CD3-) and their activation markers (CD16, CD314, and CD335) will be assessed 
by flow cytometry because the primary mechanism of action of talacotuzumab is antibody-
dependent cellular cytotoxicity (ADCC) through NK cells.
Proteomic Analysis
Peripheral blood plasma will be analyzed for protein expression associated with disease 
progression or response to talacotuzumab or daratumumab.
9.5.
Safety Evaluations
All subjects who receive at least one dose of talacotuzumab or daratumumab will be considered 
evaluable for safety. Any clinically relevant changes occurring during the study must be recorded 
in the Adverse Event section of the eCRF. Any serious adverse events persisting at the end of the 
study/early withdrawal will be followed by the investigator until resolution or until a clinically 
stable endpoint is reached. A sponsor safety review committee will review all the safety data on 
a quarterly basis, or ad hoc, as needed (see Section 11.9).
The study will include the following evaluations of safety and tolerability according to the time 
points provided in the Time and Events Schedules:
Adverse Events
Adverse events (AEs) will be reported by the subject (or, when appropriate, by a caregiver, 
surrogate, or the subject's legally acceptable representative) for the duration of the study (ie, from 
the time of signing ICF until 30 days after the end of dosing or until the start of subsequent 
anticancer treatment, if earlier). Adverse events will be reported and graded according to the 
National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), 
Version 4.03. Adverse events will be followed by the investigator as specified in Section 12, 
Adverse Event Reporting.
The follow-up of subjects in the study and study data collection will end either 1 year after the 
last subject is randomized or anytime the sponsor terminates the study. Subjects who are 
continuing to derive benefit from daratumumab treatment after study data collection ends as 
assessed by their investigator may continue to receive daratumumab according to the protocol. 
During this period after study data collection has ended, only serious adverse events will be

monitored and only entered into the company safety repository as described under Amendment 4 
and in the Time and Events Schedules.
Clinical Laboratory Tests 
Required laboratory tests must be performed within 48 hours of the scheduled visit. For Cycle 1 
Day 1 only, clinical laboratory tests do not need to be repeated if the Screening tests were 
performed within 5 days of the first dose of study treatment.
The investigator must review the laboratory results, document this review, and record any 
clinically relevant changes occurring during the study in the adverse event section of the eCRF. 
For example, laboratory abnormalities leading to an action regarding any study treatment (dose 
reduction, temporary stop, delay of the start of a cycle or permanent stop) or the start of 
concomitant therapy should be reported. For each laboratory abnormality reported as an adverse 
event, the following laboratory values should be reported in the laboratory section of the eCRF: 
the value indicative of the onset of each toxicity grade; the most abnormal value observed during 
the adverse event, and the value supporting recovery to Grade ≤1 or to baseline values.
The following tests will be performed by the local laboratory at the timepoints shown in the 
Time and Events Schedules:

Hematology: hemoglobin, platelet count, white blood cell count, manual absolute peripheral 
blast count, absolute neutrophil count (ANC)

Serum Chemistry: Creatinine, total bilirubin (with fractionation if abnormal), ALT, AST, 
alkaline phosphatase (ALP), lactate dehydrogenase, albumin, serum EPO, serum ferritin,
and transferrin saturation

Serum -hCG or urine pregnancy testing for women of childbearing potential only 
(screening only) or if clinically indicated or required by local regulations

Serology (HIV antibody, hepatitis B surface antigen [HBsAg], and hepatitis C virus 
antibody)
Electrocardiogram (ECG) 
A 12-lead electrocardiogram will be performed in all subjects during Screening and on Day 1 of 
Cycle 1. 
During the collection of ECG, subjects should be in a quiet setting without distractions 
(eg, television, cell phones). Subjects should rest in a supine position for at least 5 minutes 
before ECG collection and should refrain from talking or moving arms or legs. If blood sampling 
or vital sign measurement is scheduled for the same timepoint as ECG recording, the procedures 
should be performed in the following order: ECG(s), vital signs, blood draw.
ECOG Performance Status
The ECOG performance status scale will be used to grade changes in the subject’s activities of 
daily living.

Vital Signs 
Pulse and blood pressure will be recorded, preferably while the subject is seated, at the time 
points specified in the Time and Events Schedules. Vital signs that are considered to be clinically 
relevant by the investigator are to be documented as adverse events.
Physical Examination 
Screening physical examination should include body weight, height, and the evaluation of head, 
eye, ear, nose, and throat; cardiovascular, dermatological, musculoskeletal, respiratory, 
gastrointestinal, and neurological systems. Only a limited symptom-directed physical 
examination and weight assessment is required on Day 1 of all cycles after baseline. New or
worsened abnormalities should be recorded as adverse events if appropriate.
9.5.1.
Indirect Antiglobulin Test (IAT)
Blood Type, Rh, and IAT should be done before the first dose of daratumumab. Subject RBC 
phenotyping (standard or extended) is an alternative option to the IAT test, if locally required. 
Either method must be completed prior to first daratumumab infusion.
Daratumumab interferes with the Indirect Antiglobulin Test (IAT), which is a routine pre-
transfusion test performed to identify a patient’s antibodies to minor antigens so that suitable 
donor blood can be given for transfusion. Daratumumab does not interfere with ABO/RhD 
typing. CD38 is expressed at very low levels on erythrocytes. Daratumumab binds to the CD38 
on erythrocytes, which results in a positive IAT (Indirect Coombs Test). This positive result 
masks the detection of antibodies to minor antigens and may prevent or delay blood banks from 
issuing donor blood for transfusion. This effect occurs during daratumumab treatment and for up 
to 6 months after treatment ends. Subjects will receive a patient identification wallet card for the 
study that includes the blood profile (ABO, Rh, and IAT or phenotyping) determined before the 
first infusion of daratumumab along with information on the IAT interference for healthcare 
providers/blood banks. Subjects are to carry this card throughout the treatment period and for at 
least 6 months after treatment ends. Blood banks can eliminate the daratumumab interference 
with IAT by treating reagent RBCs with dithiothreitol (DTT).1
Possible methods for blood banks to provide safe RBCs for transfusion to subjects receiving 
daratumumab include:
a) Providing ABO/RhD compatible, phenotypically (standard or extended phenotyping) or 
genotypically matched units
b) Providing ABO/RhD compatible, K-negative units after ruling out or identifying 
alloantibodies using DTT-treated reagent RBCs
Uncrossmatched, ABO/RhD compatible RBC units should be administered if transfusion is 
needed emergently as per local blood bank practice.

Prophylaxis for Herpes Zoster Reactivation
Prophylaxis for herpes zoster reactivation is recommended during the Treatment Phase for 
subjects enrolled in the daratumumab arm, as per institutional guidelines.
9.6.
Sample Collection and Handling
The actual dates and times of sample collection must be recorded in the eCRF or laboratory 
requisition form. Refer to the Time and Events Schedules for the timing and frequency of all 
sample collections. Instructions for the collection, handling, storage, and shipment of samples are 
found in the laboratory manual that will be provided.

SUBJECT COMPLETION/DISCONTINUATION OF STUDY TREATMENT/ 
WITHDRAWAL FROM THE STUDY
10.1.
Completion
A subject will be considered to have completed the study if he or she has died or has been lost to 
follow-up. All other subjects will be followed until the end of the study. The end of study data 
collection is defined as either 1 year after the last subject is randomized or anytime the sponsor 
terminates the study. At that time, study follow-up of subjects and study data collection will end. 
Subjects who are continuing to derive benefit from daratumumab treatment as assessed by their 
investigator may continue to receive daratumumab according to the protocol. During this period 
after study data collection has ended, only serious adverse events will be monitored and only 
entered into the company safety repository as described under Amendment 4 and in the Time and 
Events Schedule.
10.2.
Discontinuation of Study Treatment/Withdrawal from the Study
If a subject’s study drug must be discontinued, this will not result in automatic withdrawal of the 
subject from the study.
Discontinuation of Study Treatment
A subject's study treatment must be discontinued if:

The investigator believes that for safety reasons (eg, adverse event) it is in the best interest 
of the subject to discontinue study treatment

The subject becomes pregnant 

The subject experiences disease progression or relapse

The subject refuses further treatment

A serious protocol violation has occurred, as determined by the principal investigator or the 
sponsor

Status: Approved, Date: 13 December 2018
End-of-treatment and posttreatment follow-up assessments should be obtained. The reason(s) a 
subject discontinues treatment will be recorded on the eCRF.
Withdrawal From the Study
A subject will be withdrawn from the study for any of the following reasons:

Lost to follow-up

Withdrawal of consent

The sponsor discontinues the study 
If a subject is lost to follow-up, every reasonable effort must be made by the study-site personnel 
to contact the subject and determine the reason for discontinuation/withdrawal. The measures 
taken to follow-up must be documented.
When a subject withdraws before completing the study, the reason for withdrawal is to be 
documented in the eCRF and in the source document. Study drug assigned to the withdrawn 
subject may not be assigned to another subject. Subjects who withdraw will not be replaced. If a 
subject withdraws from the study before the end of the Treatment Phase, end-of-treatment and 
posttreatment follow-up assessments should be obtained, unless the subject withdraws consent.
10.3.
Withdrawal From the Use of Research Samples
Withdrawal From the Use of Samples in Future Research 
The subject may withdraw consent for use of samples for research (refer to Section 16.2.5, Long-
Term Retention of Samples for Additional Future Research). In such a case, samples will be 
destroyed after they are no longer needed for the clinical study. Details of the sample retention 
for research are presented in the main ICF.

STATISTICAL METHODS
Statistical analysis will be done by the sponsor or under the authority of the sponsor. A general 
description of the statistical methods to be used to analyze the efficacy and safety data is outlined 
below. Specific details will be provided in the Statistical Analysis Plan (SAP). 
11.1.
Subject Information
Efficacy and safety analyses will be performed using the Treated Population, which will include 
all subjects who received at least 1 dose of study drug.
The PK/PD evaluable population will consist of all subjects who received at least 1 dose of study 
drug and had at least 1 sample collected during treatment to determine the drug concentration or 
PD biomarker response. Continuous variables will be summarized using descriptive statistics 
such as mean, median, standard deviation, 25th and 75th percentiles, and range. Categorical 
variables will be summarized using frequency tables. For time-to-event variables, the Kaplan-
Meier method will be used for descriptive summaries.

Status: Approved, Date: 13 December 2018
11.2.
Sample Size Determination
On the basis of historical data, the TI rate with treatment of best supportive care is expected to be 
approximately 2.5% in subjects with low or intermediate-1 risk MDS.17 The primary objective is 
to evaluate the likelihood that treatment with talacotuzumab or daratumumab can result in a true 
TI rate ≥30%. A true TI rate ≤15% (6 times of the TI rate of best supportive care) will be 
considered as of no clinical interest in the context of this Phase 2 study. The number of subjects 
to be randomized into each arm will be 30, with which the lower boundary of the 2-sided 80% 
credible interval will exceed 15% if ≥8 (26.7%) subjects achieve TI. This sample size 
determination utilizes a Bayesian approach with Beta(0.5, 0.5) as the prior distribution and 
Beta(0.5+m, 0.5+30-m) as the posterior distribution for the true TI rate, where m is the observed 
number of subjects who achieve TI.
11.3.
Efficacy Analyses 
Primary Endpoint
The primary efficacy endpoint is RBC TI, lasting for at least 8 weeks.
There is no statistical hypothesis testing and no formal statistical comparison between the 
2 arms.
Based on the observed number of subjects achieving TI (number of TIs), a Bayesian approach 
will be used to determine if the outcome of each treatment arm is “meeting” or “not meeting” the 
primary objective, or statistically “inconclusive.” This statistical assessment will be used to guide 
decision making for further development of either or both compounds. The evaluation will be 
performed against the target value (TV) of 30% and the minimum acceptable value (MAV) 15% 
for the TI rate. The TV of 30% is defined according to study primary objective and is deemed 
clinically meaningful. A TI rate below 15%, the MAV, will be of no clinical interest. TI rates 
between MAV and TV will be considered modest, which will define a statistically inconclusive 
outcome. Operating characteristics (false positive and false negative error rates) of the statistical 
criteria are calculated using a Bayesian approach with Beta(0.5, 0.5) as the prior distribution and 
Beta(0.5+m, 0.5+30-m) as the posterior distribution of the true TI rate, where m is the observed 
number of TIs. 
The TI rate point-estimate and corresponding 2-sided 80% credible interval (CI) will also be 
summarized for each treatment arm.
The above statistical inferences are summarized in the Table 7.
The lower boundary of the 2-sided 80% credible interval will exceed 15% (the MAV) if the 
observed number of TI is ≥8. If number of TIs is ≥13, then the outcome will be considered 
highly desirable as the lower boundary of the credible interval will exceed 30% (the TV). If the 
number of TIs is ≤5, then this will be an undesirable outcome as the upper bound of the credible 
interval is below 30%. When outcomes are statistically inconclusive (number of TI=6 or 7), 
results of additional sensitivity analyses and other endpoints (secondary, safety, PK, 
PD/biomarker) will play a more important role in decision making.

In addition to the aforementioned statistical assessments, sensitivity analyses will also be 
performed for the primary endpoint. In these analyses, additional subjects will also be considered 
transfusion independent if they are transfusion-free for less than 8 weeks but have maintained 
such a status for at least 6 consecutive weeks (42 days) by the time of the clinical cutoff 
(6 months after last randomization).
Secondary Endpoints
The proportion of subjects with TI lasting at least 168 days (24 weeks), CR, PR, and HI will be
summarized descriptively.
The distributions of time to TI, and duration of TI will be estimated for each treatment arm using
Kaplan-Meier method. These analyses will be based on subjects who achieve TI.
Other time-to-event endpoints including OS and time to progression to AML will be analyzed 
using Kaplan-Meier methods.
11.4.
Pharmacokinetic Analyses 
Data for all subjects who have sufficient and interpretable data for treatment with talacotuzumab 
or daratumumab will be included in both the PK and the PD analysis. Descriptive statistics 
(geometric and arithmetic means, standard deviation, and coefficient of variation [%]) will be 
provided to summarize serum concentrations of talacotuzumab or daratumumab at each sampling 
time point and PK parameters such as: Cmax and Cmin as appropriate.
Pharmacokinetic analyses will be performed on the PK-evaluable population, defined as subjects 
who have received at least 1 dose of talacotuzumab or daratumumab and have at least 1 
postinfusion sample.

Status: Approved, Date: 13 December 2018
All concentrations below the lowest quantifiable concentration or missing data will be labeled as 
such in the concentration database. Concentrations below the lowest quantifiable concentration 
will be treated as zero in the summary statistics. The number of subjects and samples excluded 
from the analysis will be clearly documented in the Clinical Study Report.
Descriptive statistics will be used to summarize talacotuzumab or daratumumab serum 
concentrations at each sampling time point. Cmin is defined as the minimal concentration 
observed immediately before infusion and Cmax is defined as the maximum concentration 
observed at the end of infusion, as presented in the summary of serum concentration by sampling 
timepoint. Other PK parameters, if available, may also be summarized. 
If sufficient data are available, population-PK analysis of serum concentration-time data of 
talacotuzumab or daratumumab may be performed and may be combined with data from other 
studies. If the population-PK analysis is conducted, details will be given in a population-PK 
analysis plan and the results of the analysis will be presented in a separate report.
11.5.
Immunogenicity Analyses 
The incidence of anti-talacotuzumab and anti-daratumumab antibodies will be summarized for 
all subjects who receive at least 1 dose of talacotuzumab and daratumumab and have appropriate 
samples for detection of antibodies to talacotuzumab and daratumumab (ie, subjects with at least 
1 sample obtained after their first dose of talacotuzumab and daratumumab). A listing of subjects 
positive for anti-talacotuzumab or anti-daratumumab antibodies will also be presented.
11.6.
Biomarker Analyses
Biomarker measures and the change from baseline will be listed, tabulated, and plotted where 
appropriate. Subjects may be grouped by treatment, biomarker subgroups, or clinical response. 
Correlation of baseline or changes of biomarkers with clinical parameters will be analyzed by 
appropriate statistical methods (eg, parametric or non-parametric, univariate or multivariate).
Results of biomarker analyses may be presented in a separate report. Planned biomarker analyses 
may be deferred if emerging study data show no likelihood of providing useful scientific 
information. 
11.7.
Pharmacokinetic/Pharmacodynamic Analyses
If sufficient data are available, pharmacokinetic/pharmacodynamic modeling may be performed, 
including exploring the relationship between serum concentrations of talacotuzumab or 
daratumumab and biomarkers, PD markers, and endpoints of clinical efficacy and safety, and 
may include data from other studies. If these analyses are performed, the details and results will 
be presented in a separate report.
11.8.
Safety Analyses
Safety analyses will be performed using the Treated Population. Safety will be evaluated using 
the NCI-CTCAE (Version 4.03). The safety parameters to be evaluated are the incidence, 
intensity, and type of adverse events, clinically significant changes in the subject’s physical

examination findings, vital signs measurements, clinical laboratory results (hematology and 
chemistry), and deaths. Exposure to study treatment and reasons for discontinuation will be 
tabulated. 
Adverse Events
Treatment-emergent adverse events are adverse events that occur after the first dose of study 
drug through 30 days following the last dose of study drug; any adverse event considered study 
drug-related regardless of the start date of the event; or any event that is present at baseline but 
worsens in severity or is subsequently considered drug-related by the investigator. Treatment-
emergent adverse events will be summarized by System Organ Class and preferred term, by 
intensity (NCI-CTCAE, Version 4.03), and by drug relationship.
The verbatim terms used in the eCRF by investigators to identify adverse events will be coded 
using the Medical Dictionary for Regulatory Activities (MedDRA).
Clinical Laboratory Tests
Laboratory data will be summarized by type of laboratory test. Reference ranges and markedly 
abnormal results (specified in the Statistical Analysis Plan) will be included in the summary of 
laboratory data. Descriptive statistics will be calculated for each laboratory analyte at baseline.
Parameters with predefined NCI-CTCAE toxicity grades will be summarized. A summary of the 
shifts in selected laboratory hematology and serum chemistry parameters from baseline to the 
worst toxicity grade during the study will be provided. The worst toxicity grade during the study 
will be tabulated.
Electrocardiogram 
Electrocardiogram data will be listed.
Vital Signs
Descriptive statistics of temperature, heart rate, and blood pressure (systolic and diastolic) values 
and changes from baseline will be summarized at each scheduled time point. The percentage of 
subjects with values beyond clinically important limits will be summarized.
11.9.
Safety Review
A sponsor safety review committee will review all the safety data on a quarterly basis, or ad hoc, 
as needed. Committee members include study team clinicians and company safety officer. 
12.
ADVERSE EVENT REPORTING
Timely, accurate, and complete reporting and analysis of safety information from clinical studies 
are crucial for the protection of subjects, investigators, and the sponsor, and are mandated by 
regulatory agencies worldwide. The sponsor has established Standard Operating Procedures in 
conformity with regulatory requirements worldwide to ensure appropriate reporting of safety 
information; all clinical studies conducted by the sponsor or its affiliates will be conducted in 
accordance with those procedures.

Status: Approved, Date: 13 December 2018
Method of Detecting Adverse Events and Serious Adverse Events
Care will be taken not to introduce bias when detecting adverse events or serious adverse events. 
Open-ended and nonleading verbal questioning of the subject is the preferred method to inquire 
about adverse event occurrence. For some studies, subjects are not always able to provide valid 
verbal responses to open-ended questions. In these circumstances, caregivers or guardians would 
provide information regarding adverse event occurrence.
Solicited Adverse Events
Solicited adverse events are predefined local and systemic events for which the subject is 
specifically questioned.
12.1.
Definitions
12.1.1.
Adverse Event Definitions and Classifications
Adverse Event
An adverse event is any untoward medical occurrence in a clinical study subject administered a 
medicinal (investigational or non-investigational) product. An adverse event does not necessarily 
have a causal relationship with the treatment. An adverse event can therefore be any unfavorable 
and unintended sign (including an abnormal finding), symptom, or disease temporally associated 
with the use of a medicinal (investigational or non-investigational) product, whether or not 
related to that medicinal (investigational or non-investigational) product. (Definition per 
International Conference on Harmonisation [ICH]).
This includes any occurrence that is new in onset or aggravated in severity or frequency from the 
baseline condition, or abnormal results of diagnostic procedures, including laboratory test 
abnormalities.
Note: The sponsor collects adverse events starting with the signing of the ICF (refer to 
Section 12.3.1, All Adverse Events, for time of last adverse event recording).
Serious Adverse Event
A serious adverse event based on ICH and EU Guidelines on Pharmacovigilance for Medicinal 
Products for Human Use is any untoward medical occurrence that at any dose:

Results in death

Is life-threatening
(The subject was at risk of death at the time of the event. It does not refer to an event that 
hypothetically might have caused death if it were more severe.)

Requires inpatient hospitalization or prolongation of existing hospitalization

Results in persistent or significant disability/incapacity

Is a congenital anomaly/birth defect

Is a suspected transmission of any infectious agent via a medicinal product

Clinical Protocol 56022473MDS2002 – Amendment 4
63
Status: Approved, Date: 13 December 2018

Is Medically Important*
*Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
also appropriate in other situations, such as important medical events that may not be 
immediately life threatening or result in death or hospitalization but may jeopardize the subject 
or may require intervention to prevent one of the other outcomes listed in the definition above. 
These should usually be considered serious.
If a serious and unexpected adverse event occurs for which there is evidence suggesting a causal 
relationship between the study drug and the event (eg, death from anaphylaxis), the event must 
be reported as a serious and unexpected suspected adverse reaction even if it is a component of 
the study endpoint (eg, all-cause mortality).
Unlisted (Unexpected) Adverse Event/Reference Safety Information
An adverse event is considered unlisted if the nature or severity is not consistent with the 
applicable product reference safety information. For talacotuzumab and daratumumab, the
expectedness of an adverse event will be determined by whether or not it is listed in the 
Investigator's Brochure. 
Adverse Event Associated With the Use of the Drug
An adverse event is considered associated with the use of the drug if the attribution is possible, 
probable, or very likely by the definitions listed in Section 12.1.2, Attribution Definitions.
12.1.2.
Attribution Definitions
Not Related
An adverse event that is not related to the use of the drug.
Doubtful
An adverse event for which an alternative explanation is more likely, eg, concomitant drug(s), 
concomitant disease(s), or the relationship in time suggests that a causal relationship is unlikely.
Possible
An adverse event that might be due to the use of the drug. An alternative explanation, 
eg, concomitant drug(s), concomitant disease(s), is inconclusive. The relationship in time is 
reasonable; therefore, the causal relationship cannot be excluded.
Probable
An adverse event that might be due to the use of the drug. The relationship in time is suggestive 
(eg, confirmed by dechallenge). An alternative explanation is less likely, eg, concomitant 
drug(s), concomitant disease(s).

Status: Approved, Date: 13 December 2018
Very Likely
An adverse event that is listed as a possible adverse reaction and cannot be reasonably explained 
by an alternative explanation, eg, concomitant drug(s), concomitant disease(s). The relationship 
in time is very suggestive (eg, it is confirmed by dechallenge and rechallenge).
12.1.3.
Severity Criteria 
The severity assessment for an adverse event/SAE should be completed using the NCI-CTCAE 
Version 4.03. Any adverse event/SAE not listed in the NCI-CTCAE will be graded by the 
investigator using the standard grades as follows:
Grade 1 (Mild): Awareness of symptoms that are easily tolerated, causing minimal discomfort 
and not interfering with everyday activities.
Grade 2 (Moderate): Sufficient discomfort is present to cause interference with normal activity.
Grade 3 (Severe): Extreme distress, causing significant impairment of functioning or 
incapacitation. Prevents normal everyday activities.
Grade 4: Life-threatening of disabling adverse event
Grade 5: Death related to the adverse event
The investigator should use clinical judgment in assessing the severity of events not directly 
experienced by the subject (eg, laboratory abnormalities).
12.2.
Special Reporting Situations
Safety events of interest on a sponsor study drug that may require expedited reporting or safety 
evaluation include, but are not limited to:

Overdose of a sponsor study drug

Suspected abuse/misuse of a sponsor study drug

Accidental or occupational exposure to a sponsor study drug

Medication error involving a sponsor product (with or without subject/patient exposure to 
the sponsor study drug, eg, name confusion)

Exposure to a sponsor study drug from breastfeeding
Special reporting situations should be recorded in the eCRF. Any special reporting situation that 
meets the criteria of a serious adverse event should be recorded on the serious adverse event page 
of the eCRF.

Procedures
12.3.1.
All Adverse Events
All adverse events and special reporting situations, whether serious or non-serious, will be 
reported from the time a signed and dated ICF is obtained until completion of the subject's last 
study-related procedure, which may include contact for follow-up of safety. Serious adverse 
events, including those spontaneously reported to the investigator within 30 days after the last 
dose of study drug, and those that are considered related to study treatment occurring within the 
Follow-up Phase, must be reported using the Serious Adverse Event Form. The sponsor will 
evaluate any safety information that is spontaneously reported by an investigator beyond the time 
frame specified in the protocol.
All events that meet the definition of a serious adverse event will be reported as serious adverse 
events, regardless of whether they are protocol-specific assessments. Anticipated events will be 
recorded and reported as described in Attachment 9. 
The follow-up of subjects in the study and study data collection will end either 1 year after the 
last subject is randomized or anytime the sponsor terminates the study. Subjects who are 
continuing to derive benefit from daratumumab treatment as assessed by their investigator may 
continue to receive daratumumab according to the protocol. During this period after study data 
collection has ended, only serious adverse events will be monitored and only entered into the 
company safety repository as described under Amendment 4 and in the Time and Events 
Schedule.
All adverse events, regardless of seriousness, severity, or presumed relationship to study drug, 
must be recorded using medical terminology in the source document and the eCRF. Whenever 
possible, diagnoses should be given when signs and symptoms are due to a common etiology 
(eg, cough, runny nose, sneezing, sore throat, and head congestion should be reported as "upper 
respiratory infection"). Investigators must record in the eCRF their opinion concerning the 
relationship of the adverse event to study therapy. All measures required for adverse event 
management must be recorded in the source document and reported according to sponsor 
instructions.
The sponsor assumes responsibility for appropriate reporting of adverse events to the regulatory 
authorities. The sponsor will also report to the investigator (and the head of the investigational 
institute where required) all suspected unexpected serious adverse reactions (SUSARs). For 
anticipated events reported as individual serious adverse events the sponsor will make a 
determination of relatedness in addition to and independent of the investigator’s assessment. The 
sponsor will periodically evaluate the accumulating data and, when there is sufficient evidence 
and the sponsor has determined there is a reasonable possibility that the drug caused a serious 
anticipated event, they will submit a safety report in narrative format to the investigators (and the 
head of the investigational institute where required). The investigator (or sponsor where 
required) must report SUSARs to the appropriate Independent Ethics Committee/Institutional 
Review Board (IEC/IRB) that approved the protocol unless otherwise required and documented 
by the IEC/IRB.

For all studies with an outpatient phase, including open-label studies, the subject must be 
provided with a "wallet (study) card" and instructed to carry this card with them for the duration 
of the study indicating the following: 

Study number

Statement, in the local language(s), that the subject is participating in a clinical study

Investigator's name and 24-hour contact telephone number

Local sponsor's name and 24-hour contact telephone number (for medical staff only)

Site number

Subject number
12.3.2.
Serious Adverse Events
All serious adverse events occurring during the study must be reported to the appropriate sponsor 
contact person by study-site personnel within 24 hours of their knowledge of the event.
Information regarding serious adverse events will be transmitted to the sponsor using the Serious 
Adverse Event Form, which must be completed and signed by a physician from the study site, 
and transmitted to the sponsor within 24 hours. The initial and follow-up reports of a serious 
adverse event should be made by facsimile (fax).
All serious adverse events that have not resolved by the end of the study, or that have not 
resolved upon discontinuation of the subject's participation in the study, must be followed until 
any of the following occurs:

The event resolves

The event stabilizes

The event returns to baseline, if a baseline value/status is available

The event can be attributed to agents other than the study drug or to factors unrelated to 
study conduct

It becomes unlikely that any additional information can be obtained (subject or health care 
practitioner refusal to provide additional information, lost to follow-up after demonstration 
of due diligence with follow-up efforts)
Suspected transmission of an infectious agent by a medicinal product will be reported as a 
serious adverse event. Any event requiring hospitalization (or prolongation of hospitalization) 
that occurs during the course of a subject's participation in a study must be reported as a serious 
adverse event, except hospitalizations for the following:

Hospitalizations not intended to treat an acute illness or adverse event (eg, social reasons 
such as pending placement in long-term care facility)

Surgery or procedure planned before entry into the study (must be documented in the 
eCRF). Note: Hospitalizations that were planned before the signing of the ICF, and where

Status: Approved, Date: 13 December 2018
the underlying condition for which the hospitalization was planned has not worsened, will 
not be considered serious adverse events. Any adverse event that results in a prolongation of 
the originally planned hospitalization is to be reported as a new serious adverse event.

For convenience the investigator may choose to hospitalize the subject for the duration of 
the treatment period.
Disease progression should not be recorded as an adverse event or serious adverse event term; 
instead, signs and symptoms of clinical sequelae resulting from disease progression/lack of 
efficacy will be reported if they fulfill the serious adverse event definition (refer to 
Section 12.1.1, Adverse Event Definitions and Classifications).
12.3.3.
Pregnancy
All initial reports of pregnancy in female subjects or partners of male subjects must be reported 
to the sponsor by the study-site personnel within 24 hours of their knowledge of the event using 
the appropriate pregnancy notification form. Abnormal pregnancy outcomes (eg, spontaneous 
abortion, fetal death, stillbirth, congenital anomalies, ectopic pregnancy) are considered serious 
adverse events and must be reported using the Serious Adverse Event Form. Any subject who 
becomes pregnant during the study must be promptly withdrawn from the study and discontinue 
further study treatment. 
Because the effect of the study drug on sperm is unknown, pregnancies in partners of male

PRODUCT QUALITY COMPLAINT HANDLING
A product quality complaint (PQC) is defined as any suspicion of a product defect related to 
manufacturing, labeling, or packaging, ie, any dissatisfaction relative to the identity, quality, 
durability, or reliability of a product, including its labeling or package integrity. A PQC may 
have an impact on the safety and efficacy of the product. Timely, accurate, and complete 
reporting and analysis of PQC information from studies are crucial for the protection of subjects, 
investigators, and the sponsor, and are mandated by regulatory agencies worldwide. The sponsor 
has established procedures in conformity with regulatory requirements worldwide to ensure 
appropriate reporting of PQC information; all studies conducted by the sponsor or its affiliates 
will be conducted in accordance with those procedures.

Drug Accountability
The investigator is responsible for ensuring that all study drug received at the site is inventoried 
and accounted for throughout the study. The study drug administered to the subject must be 
documented on the drug accountability form. All study drug will be stored and disposed of 
according to the sponsor's instructions. Study-site personnel must not combine contents of the 
study drug containers.
Study drug must be handled in strict accordance with the protocol and the container label, and 
must be stored at the study site in a limited-access area or in a locked cabinet under appropriate 
environmental conditions. Unused study drug, and study drug returned by the subject, must be 
available for verification by the sponsor's study site monitor during on-site monitoring visits. The 
return to the sponsor of unused study drug, or used returned study drug for destruction, will be 
documented on the drug return form. When the study site is an authorized destruction unit and 
study drug supplies are destroyed on-site, this must also be documented on the drug return form.
Potentially hazardous materials such as used ampules, needles, syringes and vials containing 
hazardous liquids, should be disposed of immediately in a safe manner and therefore will not be 
retained for drug accountability purposes. 
Study drug should be dispensed under the supervision of the investigator or a qualified member 
of the study-site personnel, or by a hospital/clinic pharmacist. Study drug will be supplied only 
to subjects participating in the study. Returned study drug must not be dispensed again, even to 
the same subject. Study drug may not be relabeled or reassigned for use by other subjects. The 
investigator agrees neither to dispense the study drug from, nor store it at, any site other than the 
study sites agreed upon with the sponsor.
The end of study data collection is defined as either 1 year after the last subject is randomized or 
anytime the sponsor terminates the study. At that time, study follow-up of subjects and study 
data collection will end. Subjects who are continuing to derive benefit from daratumumab 
treatment as assessed by their investigator may continue to receive daratumumab according to 
the protocol. During this period after study data collection has ended, only serious adverse events 
will be monitored and only entered into the company safety repository as described under 
Amendment 4 and in the Time and Events Schedule.

ETHICAL ASPECTS
16.1.
Study-Specific Design Considerations
This is a proof-of-concept study that evaluates talacotuzumab and daratumumab as separate 
agents in subjects with low risk MDS. There is an unmet need for agents that relieve the 
transfusion requirements, mostly RBC, for subjects with low-risk MDS. Preclinical evidence 
suggests that these agents may promote normal hematopoiesis in the bone marrow by elimination 
of immune suppressor cells and potentially improve TI. Talacotuzumab is currently being 
evaluated in a Phase 2 study in patients with AML, a myeloid disease closely related to MDS and 
is considered safe and tolerable at the dose specified in this protocol. Daratumumab has been 
approved in the US and EU for the treatment of patients with relapsed and refractory multiple 
myeloma under the regimen specified in this protocol. In the AML and MM indications, the 
health of patients is likely to be more compromised than for patients with low-risk MDS. The 
sponsor considers the potential clinical benefits to outweigh the known risks of talacotuzumab or 
daratumumab treatment for patients with low-risk MDS.
Potential subjects will be fully informed of the risks and requirements of the study and, during 
the study, subjects will be given any new information that may affect their decision to continue 
participation. They will be told that their consent to participate in the study is voluntary and may 
be withdrawn at any time with no reason given and without penalty or loss of benefits to which 
they would otherwise be entitled. Only subjects who are fully able to understand the risks, 
benefits, and potential adverse events of the study, and provide their consent voluntarily will be 
enrolled.
Treatment allocation is randomized therefore patients have equal chances of receiving either of 
the 2 experimental treatments. Patients will undergo the same procedures and testing regardless 
of which treatment that they receive. As a precautionary measure, due to benefit / risk 
considerations for patients with low-risk MDS, enrollment to the talacotuzumab arm has been 
closed based upon the occurrence of a Grade 4 infusion-related reaction in the first subject to 
receive talacotuzumab. The IWRS was modified to only permit enrollment to the daratumumab 
arm of the study.
Infusion-related reactions are associated with both agents. Several safeguards, including 
premedication regimens for both agents as well as postmedications for daratumumab, are 
mandated to reduce the occurrence or the severity of infusion-related reactions. 
Because of the cytopenias associated with MDS, routine hematology values will be monitored. 
The follow-up of subjects in the study and study data collection will end either 1 year after the 
last subject is randomized or anytime the sponsor terminates the study. Subjects who are 
continuing to derive benefit from daratumumab treatment as assessed by their investigator may 
continue to receive daratumumab according to the protocol. During this period after study data

collection has ended, only serious adverse events will be monitored and only entered into the 
company safety repository as described under Amendment 4 and in the Time and Events 
Schedule.
The total blood volume to be collected is considered to be an acceptable amount of blood for 
subjects participating in an MDS clinical study and is deemed reasonable over this time period in 
this study.
16.2.
Regulatory Ethics Compliance
16.2.1.
Investigator Responsibilities
The investigator is responsible for ensuring that the study is performed in accordance with the 
protocol, current ICH guidelines on Good Clinical Practice (GCP), and applicable regulatory and 
country-specific requirements.
Good Clinical Practice is an international ethical and scientific quality standard for designing, 
conducting, recording, and reporting studies that involve the participation of human subjects. 
Compliance with this standard provides public assurance that the rights, safety, and well-being of 
study subjects are protected, consistent with the principles that originated in the Declaration of 
Helsinki, and that the study data are credible.

must be submitted promptly to the IEC/IRB for review and approval before implementation of 
the change(s). 
At least once a year, the IEC/IRB will be asked to review and reapprove this study, where 
required.
At the end of the study, the investigator (or sponsor where required) will notify the IEC/IRB 
about the study completion. 
16.2.3.
Informed Consent 
Each subject (or a legally acceptable representative) must give written consent according to local 
requirements after the nature of the study has been fully explained. The ICF(s) must be signed 
before performance of any study-related activity. The ICF(s) that is/are used must be approved 
by both the sponsor and by the reviewing IEC/IRB and be in a language that the subject can read 
NCT03011034

Status: Approved, Date: 13 December 2018
and understand. The informed consent should be in accordance with principles that originated in 
the Declaration of Helsinki, current ICH and GCP guidelines, applicable regulatory 
requirements, and sponsor policy.
Before enrollment in the study, the investigator or an authorized member of the study-site 
personnel must explain to potential subjects or their legally acceptable representatives the aims, 
methods, reasonably anticipated benefits, and potential hazards of the study, and any discomfort 
participation in the study may entail. Subjects will be informed that their participation is 
voluntary and that they may withdraw consent to participate at any time. They will be informed 
that choosing not to participate will not affect the care the subject will receive for the treatment
of his or her disease. Subjects will be told that alternative treatments are available if they refuse 
to take part and that such refusal will not prejudice future treatment. Finally, they will be told 
that the investigator will maintain a subject identification register for the purposes of long-term 
follow-up if needed and that their records may be accessed by health authorities and authorized 
sponsor personnel without violating the confidentiality of the subject, to the extent permitted by 
the applicable law(s) or regulations. By signing the ICF the subject (or legally acceptable 
representative) is authorizing such access, which includes permission to obtain information about 
his or her survival status. It also denotes that the subject agrees to allow his or her study 
physician to recontact the subject for the purpose of obtaining consent for additional safety 
evaluations, and subsequent disease-related treatments, if needed.
The subject or legally acceptable representative will be given sufficient time to read the ICF and 
the opportunity to ask questions. After this explanation and before entry into the study, consent 
should be appropriately recorded by means of either the subject's or his or her legally acceptable 
representative's personally dated signature. After having obtained the consent, a copy of the ICF 
must be given to the subject.
If the subject or legally acceptable representative is unable to read or write, an impartial witness 
should be present for the entire informed consent process (which includes reading and explaining 
all written information) and should personally date and sign the ICF after the oral consent of the 
subject or legally acceptable representative is obtained.
16.2.4.
Privacy of Personal Data
The collection and processing of personal data from subjects enrolled in this study will be 
limited to those data that are necessary to fulfill the objectives of the study.
These data must be collected and processed with adequate precautions to ensure confidentiality 
and compliance with applicable data privacy protection laws and regulations. Appropriate 
technical and organizational measures to protect the personal data against unauthorized 
disclosures or access, accidental or unlawful destruction, or accidental loss or alteration must be 
put in place. Sponsor personnel whose responsibilities require access to personal data agree to 
keep the identity of subjects confidential.
The informed consent obtained from the subject (or his or her legally acceptable representative) 
includes explicit consent for the processing of personal data and for the investigator/institution to

Status: Approved, Date: 13 December 2018
allow direct access to his or her original medical records (source data/documents) for study-
related monitoring, audit, IEC/IRB review, and regulatory inspection. This consent also 
addresses the transfer of the data to other entities and to other countries.
The subject has the right to request through the investigator access to his or her personal data and 
the right to request rectification of any data that are not correct or complete. Reasonable steps 
will be taken to respond to such a request, taking into consideration the nature of the request, the 
conditions of the study, and the applicable laws and regulations.
Exploratory PD, biomarker, PK and immunogenicity research is not conducted under standards 
appropriate for the return of data to subjects. In addition, the sponsor cannot make decisions as to 
the significance of any findings resulting from exploratory research. Therefore, exploratory 
research data will not be returned to subjects or investigators, unless required by law or local 
regulations. Privacy and confidentiality of data generated in the future on stored samples will be 
protected by the same standards applicable to all other clinical data.
16.2.5.
Long-Term Retention of Samples for Additional Future Research 
Samples collected in this study may be stored for up to 15 years (or according to local 
regulations) for additional research. Samples will only be used to understand talacotuzumab and 
daratumumab, to understand MDS, to understand differential drug responders, and to develop 
tests/assays related to talacotuzumab and daratumumab and MDS. The research may begin at any 
time during the study or the post-study storage period. 
Stored samples will be coded throughout the sample storage and analysis process and will not be 
labeled with personal identifiers. Subjects may withdraw their consent for their samples to be 
stored for research (refer to Section 10.3, Withdrawal From the Use of Research Samples.
16.2.6.
Country Selection
This study will only be conducted in those countries where the intent is to launch or otherwise 
help ensure access to the developed product if the need for the product persists, unless explicitly 
addressed as a specific ethical consideration in Section 16.1, Study-Specific Design 
Considerations.
17.
ADMINISTRATIVE REQUIREMENTS

IEC/IRB (where required) only needs to be notified.
During the course of the study, in situations where a departure from the protocol is unavoidable, 
the investigator or other physician in attendance will contact the appropriate sponsor 
representative listed in the Contact Information page(s), which will be provided as a separate 
document. Except in emergency situations, this contact should be made before implementing any 
departure from the protocol. In all cases, contact with the sponsor must be made as soon as 
possible to discuss the situation and agree on an appropriate course of action. The data recorded 
in the eCRF and source documents will reflect any departure from the protocol, and the source 
documents will describe this departure and the circumstances requiring it.

Subject Identification, Enrollment, and Screening Logs
The investigator agrees to complete a subject identification and enrollment log to permit easy 
identification of each subject during and after the study. This document will be reviewed by the 
sponsor study-site contact for completeness.
The subject identification and enrollment log will be treated as confidential and will be filed by 
the investigator in the study file. To ensure subject confidentiality, no copy will be made. All 
reports and communications relating to the study will identify subjects by subject identification 
and date of birth. In cases where the subject is not randomized into the study, the date seen and 
date of birth will be used.
The investigator must also complete a subject screening log, which reports on all subjects who 
were seen to determine eligibility for inclusion in the study.
17.4.
Source Documentation
At a minimum, source documents consistent in the type and level of detail with that commonly 
recorded at the study site as a basis for standard medical care must be available for the following: 
subject identification, eligibility, and study identification; study discussion and date of signed 
informed consent; dates of visits; results of safety and efficacy parameters as required by the 
protocol; record of all adverse events and follow-up of adverse events; concomitant medication; 
drug receipt/dispensing/return records; study drug administration information; and date of study 
completion and reason for early discontinuation of study drug or withdrawal from the study, if 
applicable. 
The author of an entry in the source documents should be identifiable.
Specific details required as source data for the study and source data collection methods will be 
reviewed with the investigator before the study and will be described in the monitoring 
guidelines (or other equivalent document).
The minimum source documentation requirements for Section 4.1, Inclusion Criteria and 
Section 4.2, Exclusion Criteria that specify a need for documented medical history are as 
follows:
NCT03011034

77
Status: Approved, Date: 13 December 2018

Referral letter from treating physician or

Complete history of medical notes at the site

Discharge summaries
Inclusion and exclusion criteria not requiring documented medical history must be verified at a 
minimum by subject interview or other protocol required assessment (eg, physical examination, 
laboratory assessment) and documented in the source documents.
An electronic source system may be utilized, which contains data traditionally maintained in a 
hospital or clinic record to document medical care (eg, electronic source documents) as well as 
the clinical study-specific data fields as determined by the protocol. If the electronic source 
system is utilized, references made to the eCRF in the protocol include the electronic source 
system but information collected through the electronic source system may not be limited to that 
found in the eCRF. Data in this system may be considered source documentation.
17.5.
Case Report Form Completion
Case report forms are prepared and provided by the sponsor for each subject in electronic format. 
All eCRF entries, corrections, and alterations must be made by the investigator or authorized 
study-site personnel. The investigator must verify that all data entries in the eCRF are accurate 
and correct.
The study data will be transcribed by study-site personnel from the source documents onto an 
electronic CRF, if applicable. Study-specific data will be transmitted in a secure manner to the 
sponsor.
Worksheets may be used for the capture of some data to facilitate completion of the eCRF. Any 
such worksheets will become part of the subject's source documents. Data must be entered into 
eCRF in English. The CRF must be completed as soon as possible after a subject visit and the 
forms should be available for review at the next scheduled monitoring visit.
If necessary, queries will be generated in the eDC tool. If corrections to an eCRF are needed 
after the initial entry into the eCRF, this can be done in either of the following ways:

Investigator and study-site personnel can make corrections in the eDC tool at their own 
initiative or as a response to an auto query (generated by the eDC tool).

Sponsor or sponsor delegate can generate a query for resolution by the investigator and 
study-site personnel.
17.6.
Data Quality Assurance/Quality Control
Steps to be taken to ensure the accuracy and reliability of data include the selection of qualified 
investigators and appropriate study sites, review of protocol procedures with the investigator and 
study-site personnel before the study, and periodic monitoring visits by the sponsor[, and direct 
transmission of biomarker, immunogenicity and PK data from central laboratories into the 
NCT03011034

Status: Approved, Date: 13 December 2018
sponsor's data base. Written instructions will be provided for collection, handling, storage, and 
shipment of samples. 
Guidelines for eCRF completion will be provided and reviewed with study-site personnel before 
the start of the study. 
The sponsor will review eCRFs for accuracy and completeness during on-site monitoring visits 
and after transmission to the sponsor; any discrepancies will be resolved with the investigator or 
designee, as appropriate. After upload of the data into the study database they will be verified for 
accuracy and consistency with the data sources. 
17.7.
Record Retention
In compliance with the ICH/GCP guidelines, the investigator/institution will maintain all CRF 
and all source documents that support the data collected from each subject, as well as all study 
documents as specified in ICH/GCP Section 8, Essential Documents for the Conduct of a 
Clinical Trial, and all study documents as specified by the applicable regulatory requirement(s). 
The investigator/institution will take measures to prevent accidental or premature destruction of 
these documents.
Essential documents must be retained until at least 2 years after the last approval of a marketing 
application in an ICH region and until there are no pending or contemplated marketing 
applications in an ICH region or until at least 2 years have elapsed since the formal 
discontinuation of clinical development of the investigational product. These documents will be 
retained for a longer period if required by the applicable regulatory requirements or by an 
agreement with the sponsor. It is the responsibility of the sponsor to inform the 
investigator/institution as to when these documents no longer need to be retained.
If the responsible investigator retires, relocates, or for other reasons withdraws from the 
responsibility of keeping the study records, custody must be transferred to a person who will 
accept the responsibility. The sponsor must be notified in writing of the name and address of the 
new custodian. Under no circumstance shall the investigator relocate or dispose of any study 
documents before having obtained written approval from the sponsor.
If it becomes necessary for the sponsor or the appropriate regulatory authority to review any 
documentation relating to this study, the investigator/institution must permit access to such 
reports.
17.8.
Monitoring
The sponsor will use a combination of monitoring techniques (central, remote, or on-site 
monitoring) to monitor this study.
The sponsor will perform on-site monitoring visits as frequently as necessary. The monitor will 
record dates of the visits in a study site visit log that will be kept at the study site. The first post-
initiation visit will be made as soon as possible after enrollment has begun. At these visits, the 
monitor will compare the data entered into the CRF with the source documents

(eg, hospital/clinic/physician’s office medical records). The nature and location of all source 
documents will be identified to ensure that all sources of original data required to complete the 
CRF are known to the sponsor and study-site personnel and are accessible for verification by the 
sponsor study-site contact. If electronic records are maintained at the study site, the method of 
verification must be discussed with the study-site personnel. 
Direct access to source documents (medical records) must be allowed for the purpose of 
verifying that the recorded data are consistent with the original source data. Findings from this 
review will be discussed with the study-site personnel. The sponsor expects that, during 
monitoring visits, the relevant study-site personnel will be available, the source documents will 
be accessible, and a suitable environment will be provided for review of study-related 
documents. The monitor will meet with the investigator on a regular basis during the study to 
provide feedback on the study conduct.
In addition to on-site monitoring visits, remote contacts can occur. It is expected that during 
these remote contacts, study-site personnel will be available to provide an update on the progress 
of the study at the site. 
Central monitoring will take place for data identified by the sponsor as requiring central review.
17.9.
Study Completion/Termination
17.9.1.
Study Completion/End of Study
The end of study data collection is defined as 1 year after last subject has been randomized or 
anytime the sponsor terminates the study (see Section 17.9.2). At that time, study follow-up of 
subjects and study data collection will end. Subjects who are continuing to derive benefit from 
daratumumab treatment as assessed by their investigator may continue to receive daratumumab
according to the protocol. During this period after study data collection has ended, only serious 
adverse events will be monitored and only entered into the company safety repository as 
described under Amendment 4 and in the Time and Events Schedule.
17.9.2.
Study Termination
The sponsor reserves the right to close the study site or terminate the study at any time for any 
reason at the sole discretion of the sponsor. Study sites will be closed upon study completion. A 
study site is considered closed when all required documents and study supplies have been 
collected and a study-site closure visit has been performed.
The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a study site by the sponsor or investigator may include but are 
not limited to:

Failure of the investigator to comply with the protocol, the requirements of the IEC/IRB or 
local health authorities, the sponsor's procedures, or GCP guidelines

Status: Approved, Date: 13 December 2018

Inadequate recruitment of subjects by the investigator

Discontinuation of further study drug development
17.10. On-Site Audits
Representatives of the sponsor's clinical quality assurance department may visit the study site at 
any time during or after completion of the study to conduct an audit of the study in compliance 
with regulatory guidelines and company policy. These audits will require access to all study 
records, including source documents, for inspection. Subject privacy must, however, be 
respected. The investigator and study-site personnel are responsible for being present and 
available for consultation during routinely scheduled study-site audit visits conducted by the 
sponsor or its designees. 
Similar auditing procedures may also be conducted by agents of any regulatory body, either as 
part of a national GCP compliance program or to review the results of this study in support of a 
regulatory submission. The investigator should immediately notify the sponsor if he or she has 
been contacted by a regulatory agency concerning an upcoming inspection.
17.11. Use of Information and Publication
All information, including but not limited to information regarding talacotuzumab and 
daratumumab or the sponsor's operations (eg, patent application, formulas, manufacturing 
processes, basic scientific data, prior clinical data, formulation information) supplied by the 
sponsor to the investigator and not previously published, and any data, including exploratory or 
biomarker research data, generated as a result of this study, are considered confidential and 
remain the sole property of the sponsor. The investigator agrees to maintain this information in 
confidence and use this information only to accomplish this study, and will not use it for other 
purposes without the sponsor's prior written consent.
The investigator understands that the information developed in the study will be used by the 
sponsor in connection with the continued development of talacotuzumab and daratumumab, and 
thus may be disclosed as required to other clinical investigators or regulatory agencies. To permit 
the information derived from the clinical studies to be used, the investigator is obligated to 
provide the sponsor with all data obtained in the study.
The results of the study will be reported in a Clinical Study Report generated by the sponsor and 
will contain data from all study sites that participated in the study as per-protocol. Recruitment 
performance or specific expertise related to the nature and the key assessment parameters of the 
study will be used to determine a coordinating investigator. Results of exploratory or biomarker 
analyses performed after the Clinical Study Report has been issued will be reported in a separate 
report and will not require a revision of the Clinical Study Report. Study subject identifiers will 
not be used in publication of results. Any work created in connection with performance of the 
study and contained in the data that can benefit from copyright protection (except any 
publication by the investigator as provided for below) shall be the property of the sponsor as 
author and owner of copyright in such work.

Clinical Protocol 56022473MDS2002 – Amendment 4
81
Status: Approved, Date: 13 December 2018
Consistent with Good Publication Practices and International Committee of Medical Journal 
Editors guidelines, the sponsor shall have the right to publish such primary (multicenter) data 
and information without approval from the investigator. The investigator has the right to publish 
study site-specific data after the primary data are published. If an investigator wishes to publish 
information from the study, a copy of the manuscript must be provided to the sponsor for review 
at least 60 days before submission for publication or presentation. Expedited reviews will be 
arranged for abstracts, poster presentations, or other materials. If requested by the sponsor in 
writing, the investigator will withhold such publication for up to an additional 60 days to allow 
for filing of a patent application. In the event that issues arise regarding scientific integrity or 
regulatory compliance, the sponsor will review these issues with the investigator. The sponsor 
will not mandate modifications to scientific content and does not have the right to suppress 
information. For multicenter study designs and substudy approaches, secondary results generally 
should not be published before the primary endpoints of a study have been published. Similarly, 
investigators will recognize the integrity of a multicenter study by not submitting for publication 
data derived from the individual study site until the combined results from the completed study 
have been submitted for publication, within 12 months of the availability of the final data (tables, 
listings, graphs), or the sponsor confirms there will be no multicenter study publication. 
Authorship of publications resulting from this study will be based on the guidelines on 
authorship, such as those described in the Uniform Requirements for Manuscripts Submitted to 
Biomedical Journals, which state that the named authors must have made a significant 
contribution to the design of the study or analysis and interpretation of the data, provided critical 
review of the paper, and given final approval of the final version.
Registration of Clinical Studies and Disclosure of Results
The sponsor will register and disclose the existence of and the results of clinical studies as 
required by law.

Dysplastic changes should consider the normal range of dysplastic changes (modification).
† Modification to IWG response criteria.
‡ In some circumstances, protocol therapy may require the initiation of further treatment (eg, consolidation, 
maintenance) before the 4-week period. Such patients can be included in the response category into which they 
fit at the time the therapy is started. Transient cytopenias during repeated chemotherapy courses should not be
considered as interrupting durability of response, as long as they recover to the improved counts of the previous 
course.

Proposed modified International Working Group response criteria for hematologic improvement
Hematologic Improvement*
Response criteria (responses must last ≥8 weeks)†
Erythroid response 
(pretreatment, <11 g/dL)
Hb increase by ≥1.5 g/dL
Relevant reduction of units of RBC transfusions by an absolute number of at 
least 4 RBC transfusions/8 weeks compared with the pretreatment transfusion 
number in the previous 8 weeks. Only RBC transfusions given for a Hb of 
≤9 g/dL pretreatment will count in the RBC transfusion response evaluation†
Platelet response 
(pretreatment, <100 x 109/L)
Absolute increase of ≥30 x 109/L for patients starting with >20 x 109/L platelets
Increase from <20 x 109/L to >20 x 109/L and by at least 100%†
Neutrophil response 
(pretreatment, <1 x 109/L)
At least 100% increase and an absolute increase >0.5 x 109/L†
Progression or relapse after 
HI‡
At least 1 of the following:
At least 50% decrement from maximum response levels in granulocytes or 
platelets
Reduction in Hb by ≥1.5 g/dL
Transfusion dependence
∗
Pretreatment counts averages of at least 2 measurements (not influenced by transfusions) ≥1 week apart (modification).
† 
Modification to IWG response criteria.
‡ 
In the absence of another explanation such as acute infection, repeated courses of chemotherapy (modification), gastrointestinal bleeding, 
hemolysis, and so forth. It is recommended that 2 kinds of erythroid and platelet responses be reported overall as well as by the individual 
response pattern.
Notes: Deletions to the IWG response criteria are not shown. To convert hemoglobin levels (concentrations) from grams per deciliter to grams 
per liter, multiply grams per deciliter by 10.

Attachment 9: Anticipated Events
Anticipated Event
An anticipated event is an adverse event (serious or non-serious) that commonly occurs as a consequence 
of the underlying disease or condition under investigation (disease-related) or background regimen.
For the purposes of this study the following events will be considered anticipated events:

Reporting of Anticipated Events
All adverse events will be recorded in the eCRF regardless of whether considered to be anticipated events 
and will be reported to the sponsor as described in Section 12.3.1, All Adverse Events. Any anticipated 
event that meets serious adverse event criteria will be reported to the sponsor as described in 
Section 12.3.2, Serious Adverse Events. These anticipated events are exempt from expedited reporting as 
individual single cases to health authorities. However if based on an aggregate review, it is determined 
that an anticipated event is possibly related to study drug, the sponsor will report these events in an 
expedited manner.
Anticipated Event Review Committee (ARC)
An Anticipated Event Review Committee (ARC) will be established to perform reviews of pre-specified 
anticipated events at an aggregate level. The ARC is a safety committee within the sponsor’s organization 
that is independent of the sponsor’s study team. The ARC will meet to aid in the recommendation to the

the study drug.
Statistical Analysis
Details of statistical analysis of anticipated events, including the frequency of review and threshold to 
trigger an aggregate analysis of anticipated events will be provided in a separate Anticipated Events 
Safety Monitoring Plan.
