Protocol Synopsis 
Title: A Phase 2/3 Multi-center Study of Evaluate the Safety and Efficacy of Blinatumomab in 
Subjects with Relapsed/Refractory Aggressive B-Cell Non Hodgkin Lymphoma 
Study Phase: 2/3 
Indication: Aggressive B-Cell Non-Hodgkin Lymphoma (B-NHL) 
Primary Objective:  
Phase 2: 
• To estimate the complete metabolic response (CMR) rate following blinatumomab 
monotherapy administered in the second salvage (S2) treatment of transplant-eligible 
subjects with relapsed or refractory (R/R) aggressive B-NHL who have not achieved CMR1 
following standard platinum-based first salvage (S1) chemotherapy 
Phase 3: 
• To compare the CMR rates following blinatumomab to those following investigator’s choice 
(IC) S2 chemotherapy 
Secondary Objectives:  
Phase 2: 
• To evaluate additional efficacy parameters following blinatumomab treatment, including: 
- Duration of response (DOR) 
- Progression-free survival (PFS) 
- The rate of successful hematopoietic stem cell (HSC) mobilization  
• To evaluate the safety of blinatumomab in the S2 setting 
Phase 3: 
• To compare the efficacy of blinatumomab to IC chemotherapy with respect to:  
- Overall survival (OS) 
- DOR 
- The rate of successful HSC mobilization 
- Ability to proceed to hematopoietic stem cell transplant (HSCT) (both autologous and 
allogeneic) rates among responding subjects (CMR) or those in sustained partial 
metabolic response (PMR) 
- Objective response rate (ORR; CMR + PMR)  
- PFS 
• To compare the safety profile of blinatumomab to that of IC chemotherapy 
•  To compare the quality of life reported by subjects treated with blinatumomab and those 
treated with IC chemotherapy 
Phases 2 and 3 
• To characterize the pharmacokinetic (PK) parameters of blinatumomab administered to 
subjects with R/R aggressive B-NHL 
                                                
1 Response terminology reflect the response criteria used. The Lugano Classification response 
definitions for PET-CT evaluations of FDG-avid lymphomas uses the terminology CMR, PMR, 
NMR, or PMD. Corresponding designations from earlier response criteria include CR, PR, SD, 
or PD.

Exploratory Objectives: 
Phases 2 and 3: 
• To characterize the pharmacodynamic effects of blinatumomab administered in temporal 
proximity to various S1 regimens  
• To evaluate the response rate according to disease-specific features, such as 
cell-of-origin (COO), c-myc and bcl-2 rearrangements and over expression, Revised 
International Prognostic Index (R-IPI), Secondary International Prognostic Index (IPI), 
National Comprehensive Cancer Network International Prognostic Index (NCCN IPI), 
response to frontline therapy, duration of first remission 
• To evaluate the frequency of tumor-associated mutations in cell-free (CF) circulating tumor 
DNA (CT-DNA) among subjects at various time points during and after salvage treatment 
• To determine the incidence of anti-blinatumomab antibody formation 
Hypothesis (Phase 3): Administration of blinatumomab to subjects with aggressive B-NHL 
following suboptimal response to standard platinum-containing S1 chemotherapy will increase the 
CMR rate and overall survival. 
Primary Endpoint:  
Phases 2 and 3: 
• CMR as determined by central radiographic assessment of positron emission 
tomography-computed tomography (PET/CT) scans using the Lugano Classification 
Secondary Endpoints:

• Blinatumomab steady state concentration and clearance 
• Overall incidence and severity of treatment-emergent adverse events 
Exploratory Endpoints (Phase 2 and 3): 
• Pharmacodynamics, including descriptive analysis of quantitative and qualitative features of 
lymphocyte populations and serum or plasma concentrations of cytokines 
• Response rates and duration according to COO designation and c-myc and 
bcl-2 rearrangement and over expression, R-IPI, Secondary IPI, NCCN IPI, as determined 
from pretreatment specimens 
• Quantitative analysis of CF CT-DNA as determined by analysis of tumor-associated mutations 
in CF CT-DNA from plasma collected at various timepoints before, during, and after treatment 
Study Design: This is a phase 2/3 open label, multicenter trial testing blinatumomab 
monotherapy for the treatment of subjects with R/R aggressive B-NHL not achieving CMR after 
standard platinum-based chemotherapy regimens administered as S1.  This study incorporates 
multiple interim analyses for futility, efficacy, and unblinded sample-size re-estimation. In the 
phase 3 part of the study, blinatumomab will be compared to IC chemotherapy. 
The phase 2 component of the study will consist of up to a 28-day screening period, 
approximately 70 to 112 days of study treatment, a 30-day (± 3days) safety follow up, and 
long-term follow up that will conclude with the final analysis of the phase 3 component, estimated 
at 30 months after initiation of the phase 3 component.  In the event that phase 3 is not 
initiated, LTFU for phase 2 subjects will proceed as detailed in Section 7.2.7. 
For the phase 3 component, the study will consist of up to a 28-day screening period, a treatment 
period of up to approximately 168 days, a 30-day safety follow-up visit, and long-term follow up. 
Long-term follow up will conclude with the final analysis. 
In the phase 2 component, enrolled subjects will receive blinatumomab monotherapy.  In the 
phase 3 component, enrolled subjects will be randomized in a 1:1 ratio to blinatumomab or IC 
chemotherapy.  Randomization will be stratified according to the following criteria: 
• Response to S1 chemotherapy (PMR vs no metabolic response [NMR]/progressive 
metabolic disease [PMD]) 
• Cytarabine administered in S1 (eg, R-DHAP and R-ESHAP vs R-ICE and R-GDP) 
• Primary Mediastinal B-Cell Lymphoma (PMBCL) and B-cell lymphoma, unclassifiable, with 
features intermediate between DLBCL and classical Hodgkin lymphoma vs all other 
histologies of aggressive B-cell lymphoma 
All subjects enrolled in phase 2 and subjects in phase 3 randomized to the blinatumomab arm will 
receive a single 70-day cycle, with a total of 56 days of blinatumomab continuous infusion (7 days 
at 9 µg/day, 7 days at 28 µg/day, and 42 days at 112 µg/day), followed by a treatment-free period 
of 14 days.  Response will be assessed by central review of a PET/CT after this single cycle (ie, 
on approximately day 70).  
In phase 3, subjects randomized to the IC arm will receive no more than 3 cycles (maximum cycle 
length 28 days) of S2 chemotherapy prior to response assessment (see specific S2 requirements 
in Section 6.3).  Any change in the chemotherapy regimen prior to response assessment or 
without objective evidence of disease progression will be scored as treatment failure. 
Following the response assessment, subjects may undergo hematopoietic stem and progenitor 
cell (HSC) mobilization and autologous hematopoietic stem cell transplant or allogeneic HSCT. 
Subjects who demonstrate a response (PMR or CMR) to protocol-assigned therapy based on 
local assessment and who are not proceeding directly to autologous hematopoietic cell transplant 
or allogeneic HSCT may receive additional cycles of protocol-assigned therapy (maximum 
1 x 4-week cycle of blinatumomab given 7 days at 9 µg/day, 7 days at 28 µg/day, and 14 days at 
112 µg/day or a maximum of 3 cycles of IC S2 chemotherapy) starting at least 2 weeks, but not

more than 4 weeks, after the end of Cycle 1. Non-responding subjects (NMR or PMD/ 
progressive disease [PD]) are not eligible for retreatment with blinatumomab. 
Sample Size: Approximately 332 subjects will be enrolled in the study, including 36 subjects in 
phase 2 and 296 in phase 3. Of these, approximately 184 subjects will receive blinatumomab. 
Summary of Subject Eligibility Criteria: The study will enroll subjects with aggressive B-NHL, 
including DLBCL NOS, follicular lymphoma Grade 3B, Primary Mediastinal B-Cell Lymphoma, 
T-cell rich B-cell lymphoma, or DLBCL that represents transformation of indolent NHL, (including 
follicular, marginal zone, and lymphoplasmacytoid lymphoma excluding chronic lymphocytic 
leukemia or Hodgkin Lymphoma), ≥18 years of age at the time of informed consent. Subjects 
must have a biopsy-proven diagnosis of aggressive B-cell lymphoma and have received 
appropriate therapy for aggressive B-cell lymphoma, regardless of whether there had been prior 
indolent disease.  Subjects must have refractory or relapsed disease following front line treatment 
of standard multiagent chemotherapy containing an anthracycline AND an approved 
anti-CD20 agent.  Relapsed disease (prior complete response/CMR) must have an available 
biopsy demonstrating relapse of aggressive B-cell lymphoma.  For subjects with de novo 
aggressive B-cell lymphoma and refractory disease, biopsy confirmation of persistent disease is 
preferred but persistent PET positivity is acceptable at a minimum.  Subjects must have received 
standard care platinum-based chemotherapy in S1 setting, have radiographically measurable 
disease with a clearly demarcated nodal lesion at least 1.5 cm in its largest dimension or a target 
extranodal lesion at least 1.0 cm, have an Eastern Cooperative Oncology Group (ECOG) 
performance status ≤ 2, be potentially eligible for high dose chemotherapy and autologous 
hematopoietic cell transplant per institutional standards, and have required laboratory procedures 
completed within 14 days (absolute neutrophil count ≥ 1.0 x 109/L, platelets ≥ 75 x 109/L, 
creatinine clearance ≥ 50 mL/min (calculated using the Cockcroft Gault equation), aspartate 
aminotransferase/alanine aminotransferase/total bilirubin < 3x/3x/2x upper limit of normal [unless 
Gilbert’s disease or if liver involvement with lymphoma]). For a full list of eligibility criteria, please 
refer to Section 4.1 through Section 4.1.2.  
Investigational Product 
Amgen Investigational Product Dosage and Administration: Blinatumomab will be supplied 
as single-use sterile glass injection vials.  All subjects in phase 2 and subjects randomized to 
blinatumomab in phase 3 will receive blinatumomab by continuous intravenous (IV) infusion for 
1 cycle. The first cycle of blinatumomab is 70 days and includes 56 days of treatment, followed by 
a 14-day treatment-free interval.  The initial blinatumomab dose is 9 µg/day, and is escalated 
stepwise to 28 µg/day on day 8 and then 112 µg/day on day 15 until the completion of therapy, 
barring any dose modifications. Responding subjects (PMR or CMR) not proceeding directly to 
autologous hematopoietic cell transplant or allogeneic HSCT may receive a maximum of 
1 additional cycle of blinatumomab starting at least 2 weeks, but not more than 4 weeks, after the 
end of Cycle 1.  Optional Cycle 2 of blinatumomab is 4 weeks (28 days) in duration.  Cycle 2 dose 
escalation is 7 days at 9 µg/day, 7 days at 28 µg/day, and 14 days at 112 µg/day. 
Non-Amgen Non-investigational Product Dosage and Administration: Subjects randomized 
to the IC arm will receive no more than 3 cycles (maximum cycle length 28 days) of 
S2 chemotherapy prior to response assessment (recommended S2 chemotherapy are provided 
in Section 6.3). Subjects who demonstrate a response (PMR or CMR) to S2 chemotherapy based 
on local assessment and who are not proceeding directly to autologous hematopoietic cell 
transplant or allogeneic HSCT may receive a maximum of 3 additional cycles of IC 
S2 chemotherapy. 
Procedures: Written informed consent must be obtained from all subjects before any study 
specific screening procedures are performed. During the study, the following procedures will 
occur: medical history/current medical conditions, demographics, ECOG Performance Status, 
physical exam including neurologic examination, height, weight, vital signs, radiographic 
assessment, and bone marrow biopsy (select subjects).  Subjects will provide samples for 
coagulation, hematology with differential, blood chemistry profiles, urine sampling for pregnancy 
test, anti-blinatumomab antibodies, and immunoglobin (IgG, IgA, IgM). Subjects will further

provide samples for other specialty labs including CF CT-DNA, cytokines, lymphocyte subsets, 
PK samples, and a serum or urine pregnancy test for female subjects of childbearing potential.  
Research staff will document the use of concomitant medications and all reported adverse 
events.  After the last dose of blinatumomab or IC chemotherapy, subjects will undergo a safety 
follow-up visit and then enter long term follow-up.  For a full list of study procedures, including the 
timing of each procedure, please refer to Section 7 and the Schedule of Assessments (Table 5, 
Table 6, Table 7, Table 8, and Table 9).  
Statistical Considerations: For phase 2, the primary analysis will report the CMR rate among 
blinatumomab-treated subjects.  Phase 3 will test whether CMR/OS is superior in the group 
randomized to blinatumomab compared to the group randomized to IC.  The primary analysis 
(analysis 4) will be triggered by the date when 296 subjects have had the opportunity to complete 
at least 1 tumor assessment.  The final analysis (analysis 5) will test whether overall survival is 
superior in the group randomized to blinatumomab compared to the group randomized to IC.  The 
final analysis will be triggered by the date when the 236th death from a phase 3 subject is 
reported in the clinical trial database, or the study duration reaches 12 months from the last 
subject randomized. 
Descriptive statistics will be provided for selected demographics, safety, PK parameters, PD, and 
biomarker data by dose, dose schedule, and time as appropriate.  PK parameters will be 
estimated by non-compartmental analysis.  Descriptive statistics on continuous data will include 
means, medians, standard deviations and ranges, while categorical data will be summarized 
using frequency counts and percentages.  Graphical summaries of the data may also be 
presented. 
In phase 3, an external independent data monitoring committee (DMC) will oversee the interim 
analyses.  In addition, the DMC will assess safety approximately every 6 months provided 
enrollment is adequate. 
For a full description of statistical analysis methods, please refer to Section 10.

BACKGROUND AND RATIONALE 
2.1 
Disease 
The annual incidence of Non-Hodgkin’s Lymphoma (NHL) in Europe and the United 
States is estimated to be 15 to 20 cases/100.000 (Fisher and Fisher, 2004).  Diffuse 
large B-cell lymphoma (DLBCL) is the most common subtype of NHL, accounting for 
30% to 40% of cases and 13% of all hematologic disorders.  The incidence is 
approximately 8 cases per 100 000 and rises with age; the median age at diagnosis is 
70 years (Haematological Malignancy Research Network).  Morphologically similar 
entities have historically been treated in a similar manner as DLBCL, and thus are 
collectively known as aggressive B-cell lymphomas.  DLBCL as a uniform 
diagnostic entity, makes up approximately 85% of aggressive B-cell lymphomas 
(Ziepert et al, 2010).  However, distinct patterns of gene expression are observed 
within DLBCL, with different prognostic and potentially predictive implications 
(Swerdlow et al, 2016).   
Left untreated, DLBCL is uniformly fatal.  Anthracycline-based frontline chemotherapy, 
introduced in the 1970s, resulted in the long term cure of 30% of patients 
(DeVita et al, 1975).Twenty-five years later, introduction of the human-mouse chimeric 
monoclonal anti-CD20 immunoglobin G (IgG) rituximab increased the cure rate 
significantly and is now a standard agent in frontline therapy, resulting in cure for 60% of 
patients (Sehn and Gascoyne 2015).

2.1.1 
Primary Refractory or Relapsed Disease 
Patients with DLBCL who do not respond to frontline therapy, or who experience 
relapse after a remission, are generally considered incurable unless able to receive high 
dose chemotherapy (HDT) plus either autologous HSCT or allogeneic HSCT 
(Robinson et al, 2016).  HSCT is preceded by a course of salvage chemotherapy.  
“Chemoresponsivess”, indicating a partial response (PR) or complete response (CR) to 
salvage chemotherapy, has been as used as 1 criterion to define HSCT eligibility, since 
early trials demonstrated the extremely poor outcomes of patients without an objective 
response to salvage chemotherapy (Philip et al, 1987).  It is not known if responsiveness 
to newer classes of therapies, such as those that are immune-based, may also be 
sufficient to permit the successful use of HDT/HSCT. 
2.1.2 
First Salvage Chemotherapy  
The most commonly used regimens in the S1 treatment of transplant-eligible patients 
contain rituximab and a platinum-based agent such as cisplatin (eg, R-DHAP, R-GDP, 
R-ESHAP) or carboplatin (eg R-ICE) (Crump et al, 2014; Martin et al, 2008; 
Witzig et al, 2008; Kewalramani et al, 2004).  Each regimen is administered over 
4-5 days every 2-4 weeks.  Two to three cycles of therapy are given before response 
assessment.  Those with PR or CR typically undergo HSC mobilization and an additional 
1-2 cycles may be given before HDT/HSCT.  Non-responders, if offered additional 
chemotherapy, typically receive an alternative regimen. 
The efficacy of salvage regimens have been compared in 2 large, multicenter 
randomized trials, CORAL (R-DHAP vs R-ICE) and NCIC Ly.12 (R-DHAP vs R-GDP) 
(Crump et al, 2014; Gisselbrecht et al, 2010).  A third trial, ORCHARRD, tested an 
alternative anti-CD20 agent, ofatumomab, versus rituximab in combination with DHAP 
(van Imhoff et al, 2014).  An overview of the results is shown in Table 1.  The different 
response and survival rates observed in these large trials may be attributed to 
heterogeneity in patient selection criteria as well as in the nature and timing of 
post-treatment assessments.  Nonetheless, these results 1) fail to demonstrate 
superiority of any specific regimen and 2) underscore the need for new agents in the 
salvage treatment of this disease.

2.1.3 
The Importance of CR Prior to Autologous HSCT 
Retrospective, single-institution analyses are nearly uniform in demonstrating a direct 
relationship between CMR (as defined by 18-fluorodeoxyglucose-positron emission 
tomography [18FDG-PET] scanning) prior to HSCT and superior event-free survival 
(Armand et al, 2013; Derenzini et al, 2008; Dickinson et al, 2010; Roland et al, 2011; 
Sauter et al, 2015).  Pre-transplant 18FDG-PET outperformed other well established 
prognostic factors, such as secondary age-adjusted international prognostic index for 
outcomes after autologous HSCT (Hamlin et al, 2003; Sauter et al, 2015).  Therefore, 
some centers will not mobilize patients with PMR or less after 2 cycles of chemotherapy.  
A third cycle of the same salvage regimen may be used, though the efficacy is not 
documented and many non-responders discontinue after 2 cycles (Martin et al, 2008). 
2.1.4 
Later Salvage 
Patients who do not respond to S1 may be offered alternative therapies (hereafter 
referred to as S2) and HSCT provided that there is a response to S2 and that 
performance status and organ function are relatively preserved.  There is no standard

S2 regimen for transplant eligible patients.  The ESMO and NCCN guidelines are 
relatively silent on appropriate S2 regimens (Zelenetz et al, 2016; Tilly et al, 2015).  ICE, 
administered after DHAP, has been reported to provide a response rate of 
52%, including 14% CR, but these responses have been observed almost exclusively in 
patients with stable disease (SD) rather than progressive disease (PD) to 
DHAP(Simpson et al, 2007).  Results of other small, single-center retrospective analyses 
support the conclusion that standard cytotoxic therapy is of limited value in patients not 
responsive to S1 chemotherapy and that novel therapies should be explored in this 
setting (Elstrom et al, 2010; Ardeshna et al, 2005;).  
A recent report from the CORAL trial has provided outcome data on the 203 subjects 
who did not undergo autologous HSCT (primarily due to treatment failure) after 
S1 chemotherapy (Van Den Neste et al, 2016).  Eighty-two percent received additional 
chemotherapy at the discretion of the treating investigator.  Of those subjects, 
13%, 15%, and 67% had CR/unconfirmed complete response (CRu), PR, or SD/PD after 
S1, with the remainder having unknown response.  Approximately 20% of those treated 
received R-DHAP-like regimens, 20% received ICE-like regimen, and 14% receiving a 
gemcitabine-based regimen.  A variety of other regimens made up the total, but each in 
fewer than 10% of subjects.  
Among subjects achieving less than CR/CRu to second line therapy (n=177), the CR/Cru 
rate to third line therapy was 22%.  The median OS  of the entire cohort (ie, including 
those that achieved CR/Cru to second line therapy) was 4.4 months.  For subjects 
achieving CR (n=55), PR (n=24), or SD/PD (n=87), OS at 1 year 77, 44, and 13%, 
respectively.  Autologous HSCT was performed in 54, 58, and 22% of subjects with CR, 
PR, and SD/PD to S2 chemotherapy.  Thirty subjects achieved CR and underwent 
HSCT; their 1 year survival was 82%.  These results confirm that the majority of patients 
who do not respond to S1 chemotherapy are unlikely to respond to additional 
conventional chemotherapy.  However, the survival experienced by responding subjects, 
particularly those in CMR, support the objective to introduce new agents in this setting.

Amgen Investigational Product Background: Blinatumomab 
Blinatumomab (BLINCYTO, AMG 103, formerly also known as MT103 or 
bscCD19xCD3) is a member of a novel class of bispecific antibody constructs called 
BiTE, or “bispecific T-cell engagers” (Schlereth et al, 2006; Dreier et al, 2002).  
Blinatumomab is a BiTE antibody construct with dual binding specificities.  T-cells are

bound by its anti-CD3 moiety, whereas B lymphoblasts and cells are bound by the 
anti_CD19 moiety.  This unique feature of blinatumomab allows it to transiently connect 
malignant cells with T-cells, thereby inducing T-cell mediated killing of the bound 
malignant cell.  In preclinical models, blinatumomab-mediated T-cell activation involves 
the transient release of inflammatory cytokines and proliferation of T-cells.  The 
subsequent serial lysis of multiple malignant cells by a single blinatumomab-activated 
T-cell closely resembles a natural cytotoxic T-cell reaction. 
CD19 is highly expressed throughout B-cell development and is present on > 90% of 
B-cell lineage cancers including DLBCL.  The efficacy of blinatumomab has been 
evaluated in subjects with B-cell precursor acute lymphocytic leukemia (ALL) and NHL, 
including DLBCL.  
Study MT103-104 evaluated the efficacy of blinatumomab in subjects with 
relapsed/refractory B-NHL.  In this phase 1 study, subjects with relapsed/refractory NHL 
where treated with a target blinatumomab dose of 60µg/m2.  In the subset of subjects 
with DLBCL (n = 11), 2 achieved a PR and 4 achieved CR/unconfirmed complete 
response (CRu) (ORR was 55%).  Neurologic events were the dose limiting toxicity, but 
were reversible in all cases upon interruption of the infusion (Goebeler et al, 2016).  As 
of the most recent analysis, 2 of the DLBCL subjects with CR/CRu had ongoing 
responses beyond 600 days.  Of the other 2 subjects, 1 subject underwent allogeneic 
HSCT and was censored, and the other relapsed around 7 months after therapy.  
A subsequent open-label phase 2 blinatumomab study (MT-103-208) in 
relapsed/refractory DLBCL included 25 subjects (23 subjects received stepwise dosing 
and 2 a flat dose of 112 µg/day).  At baseline, the median number of prior regimens was 
3 (range 1 to 7) and all subjects had received prior rituximab.  Seven (28%) had relapsed 
after prior autologous HSCT. This study demonstrated stepwise dosing with weekly dose 
escalation of blinatumomab (9/28/112 µg/day) was tolerable and associated with 
anti-tumor activity with an ORR after 1 cycle of blinatumomab of 43% for evaluable 
subjects, including CR in 19%.  The most common adverse events were tremor, pyrexia, 
and fatigue.  Grade 3 neurologic adverse events were reported in 22% of subjects (no 
grade 4 or 5) but were generally reversible with treatment interruption 
(Viardot et al, 2016).

The single agent clinical response seen in R/R DLBCL subjects suggests blinatumomab 
may be an effective therapy to improve the low PFS/OS that occurs in 
relapse/refractory subjects with present day therapies.  
Blinatumomab (BLINCYTO) is approved in multiple regions for the treatment of 
Philadelphia chromosome-negative R/R B-cell precursor ALL.  Additionally, confirmation 
of clinical benefit is a condition of approval in multiple countries.  
Refer to the specific section of the Investigator’s Brochure for additional information 
related to the physical, chemical, and pharmaceutical properties and formulation(s). 
2.3 
Rationale 
This study in subjects with R/R aggressive B-NHL will provide an opportunity to further 
define blinatumomab’s safety and efficacy profile in this population.  The single-agent 
activity of blinatumomab observed in heavily pre-treated subjects as described above, 
coupled with the need for new agents earlier in the course of salvage treatment, 
provides a strong rationale for testing blinatumomab in this setting. 
2.4 
Clinical Hypotheses (Phase 3) 
Administration of blinatumomab to subjects with aggressive B-NHL following suboptimal 
response to standard platinum-containing S1 chemotherapy will increase the CMR rate 
and OS. 
3. 
EXPERIMENTAL PLAN 
3.1 
Study Design 
This is a phase 2/3 open label, multicenter trial testing blinatumomab monotherapy for 
the treatment of subjects with R/R aggressive B-NHL not achieving CMR after standard 
platinum-based chemotherapy regimens administered as S1.  In the phase 3 part of the 
study, blinatumomab will be compared to IC chemotherapy.  This study incorporates 
multiple interim analyses for futility, efficacy, and unblinded sample-size re-estimation, 
described further in Section 10.4.1.  The primary endpoint for both the phase 2 and 
3 components of this trial is CMR rate, determined during the first 12 weeks after 
initiation of blinatumomab or after initiationof IC chemotherapy for phase 3. 
Subjects with R/R aggressive B-NHL and considered by the investigator to be transplant 
eligible, but dependent upon the response to S2, will be enrolled after a minimum of 
2 cycles of platinum-based S1 chemotherapy or if with PMD after 1 cycle of 
platinum-based S1 chemotherapy.  In order to be eligible, subjects must undergo a 
restaging positron emission tomography/computed tomography (PET/CT) that is 
Approved

interpreted centrally as demonstrating less than CMR.  To optimize subject recruitment 
and retention, pre-screening discussions may be conducted with potential subjects prior 
to the initiation of S1 chemotherapy.  However, enrollment may not occur until the 
PET/CT results are centrally reviewed and interpreted. 
Subjects who experience clinical evidence of progression following at least 1 cycle of 
platinum-based S1 chemotherapy may be eligible but will require pre-S1 imaging and 
post-S1 PET/CT scan to confirm progression and to establish a new baseline for 
subsequent response assessment.  
In the phase 2 component, enrolled subjects will receive blinatumomab monotherapy.  In 
the phase 3 component, enrolled subjects will be randomized in a 1:1 ratio to 
blinatumomab or IC chemotherapy.  Randomization will be stratified according to the 
following criteria: 
Response to S1 chemotherapy (PMR vs no metabolic response [NMR]/ progressive 
metabolic disease [PMD]) 
Cytarabine administered in S1 (eg, R-DHAP and R-ESHAP vs R-ICE and R-GDP) 
Primary Mediastinal B-Cell Lymphoma (PMBCL) and B-cell lymphoma, unclassifiable, 
with features intermediate between DLBCL and classical Hodgkin lymphoma vs all other 
histologies of aggressive B-cell lymphoma 
Subjects in the phase 2 and subjects randomized to blinatumomab in phase 3 will 
receive a single 70-day cycle, with a total of 56 days of blinatumomab continuous 
infusion of 7 days at 9 µg/day, 7 days at 28 µg/day, and 42 days at 112 µg/days, 
followed by a treatment-free period of 14 days.  Response will be assessed by central 
review of a PET/CT within 12 weeks of initiation of blinatumomab.  
In phase 3, subjects randomized to the IC arm will receive no more than 3 cycles 
(maximum cycle length 28 days) of S2 chemotherapy prior to response assessment.  
For phase 3, investigator choice of S2 chemotherapy regimens will be designated as the 
control arm of the study.  S2 chemotherapy requirements are provided in Section 6.3.1.  
Any change in the chemotherapy regimen prior to or without objective evidence of 
disease progression will be scored as treatment failure. 
In both phase 2 and 3, following response assessment, subjects may undergo HSC 
mobilization and autologous HSCT or allogeneic HSCT.  Subjects who demonstrate a 
response (PMR or CMR) to protocol-assigned therapy based on local assessment and

who are not proceeding directly to autologous HSCT or allogeneic HSCT may receive 
additional cycles of protocol-assigned therapy (maximum 1 x 4-week cycle of 
blinatumomab or a maximum of 3 cycles of IC S2 chemotherapy).  Optional 
Cycle 2 blinatumomab dosing must start at least 2 weeks, but not more than 4 weeks, 
after the end of the previous cycle.  Optional Cycle 2 blinatumomab consists of a 28 day 
cycle of blinatumomab continuous infusion administered 7 days at 9 µg/day, 7 days at 28 
µg/day, and 14 days at 112 µg/day. 
Non-responding subjects (NMR or PMD/PD) are not eligible for retreatment with 
blinatumomab. 
All subjects will have a safety follow-up no later than 30 (± 3) days after the last dose of 
blinatumomab or 30 days (±3 days) after the last dose of IC chemotherapy 
(see Section 7.2.4). 
The overall study design is described by a study schema in Figure 1 and Figure 2, and 
the study endpoints are defined in Section 10.1.1. 
3.2 
Number of Sites 
The study will be conducted at approximately 145 sites globally.  During the conduct of 
the study additional countries, regions or sites may be added if necessary. 
Sites that do not enroll subjects within 6 months of site initiation may be closed.  
3.3 
Number of Subjects 
Participants in this clinical investigation shall be referred to as “subjects”.  
Approximately 332 subjects will participate in this study, and approximately 184 subjects 
will receive blinatumomab.  Refer to Section 10.2 for sample size considerations. 
3.4 
Replacement of Subjects 
Subjects who are withdrawn or removed from treatment or the study will not be replaced. 
3.5 
Estimated Study Duration 
3.5.1 
Study Duration for Subjects 
Phase 2: The estimated maximum duration of the study for subjects component is 
approximately 30 months.  This includes a 28-day screening period, approximately 70 to 
112 days of study treatment, a 30-day safety follow up, and long-term follow up 
approximately 2 years from safety follow up.  
Phase 3: The estimated maximum duration of the study for an individual subject is 
approximately 33 months.  This includes a 28-day screening period, a treatment period

of up to approximately 168 days, a 30-day safety follow-up visit, and long-term follow up.  
Long-term follow up will conclude with the final analysis. 
3.5.2 
End of Study 
Primary Completion: the time when the last subject is assessed or receives an 
intervention for the purposes of final collection of data for the primary analysis; the 
primary analysis will be triggered when 296 subjects in phase 3 have had the opportunity 
to complete at least 1 tumor response assessment.End of Trial: triggered by the date 
when the 236th death of a phase 3 subject is reported in the clinical trial database, or the 
study duration reaches 12 months from the last subject randomized. 
This study is event-driven and will conclude when approximately 236 death events in 
phase 3 have occurred.It is anticipated that the enrollment period will be approximately 
33 months, and the study duration will be approximately 52 months from the date that 
the first subject is enrolled, randomized (approximately 12 months from the completion 
of randomization in phase 3). 
At the end of phase 2, when all phase 2 subjects have had an opportunity to have 
a tumor assessment by week 12, a data analysis will be done to facilitate the 
decision whether to proceed to phase 3.  If the study will not continue for the 
phase 3 portion, the study will conclude when phase 2 subjects have had an 
opportunity to complete long term follow-up. 
If the study only includes the phase 2 portion, the enrollment period is 
approximately 12 months, and the study duration will be approximately 24 months 
from the date the last subject completes treatment.

SUBJECT ENROLLMENT 
Before subjects begin participation in any study-specific activities/procedures, Amgen 
requires a copy of the site’s written institutional review board/independent ethics 
committee (IRB/IEC) approval of the protocol, informed consent form (ICF), and all other 
subject information and/or recruitment material, if applicable (see Section 11.2).

The subject or the subject’s legally acceptable representative must personally sign and 
date the IRB/IEC- and Amgen-approved ICF before the commencement of study-specific 
procedures. Upon completion of the screening period the subject is evaluated by the 
investigator and providing the subject continues to meet the inclusion/exclusion criteria, 
the subject is subsequently eligible to be enrolled in the study and either randomized or 
assigned to a treatment regimen. 
For Phase 2, a subject will be considered enrolled into the study when the investigator 
decides that the subject has met all eligibility criteria and registers enrollment via IVRS.  
In Phase 3, a subject will be considered enrolled and randomized into the study when 
the investigator decides that the subject has met all eligibility criteria and a 
randomization number is provided via IVRS.  
Enrollment will occur after the centralized response assessment to S1 chemotherapy.  
Subjects with CMR (Deauville ≤ 3) will not be enrolled.  The investigator is to document 
this decision and date, in the subject’s medical record and in/on the enrollment case 
report form (CRF). 
Each subject who enters into the screening period (defined as the date when the subject 
signs the IRB/IEC-approved main study ICF) for the study receives a unique subject 
identification number before any study-related activities/procedures are performed.  The 
subject identification number will be assigned by IVRS.  This number will be used to 
identify the subject throughout the clinical study and must be used on all study 
documentation related to that subject.  
Subjects who fail screening will be allowed to re-screen once. 
The subject identification number must remain constant throughout the entire clinical 
study; it must not be changed after initial assignment, including if a subject is 
rescreened.  This number will not necessarily be the same as the randomization number 
assigned for the Phase 3 part of this study. 
5.1 
Randomization/Treatment Assignment 
Subjects enrolled during the phase 2 component will be treated with blinatumomab 
monotherapy.  An authorized site representative will make the enrollment call to the 
IVRS.  A phase 2 subject will be considered enrolled into the study when the investigator 
confirms that the subject has met all eligibility criteria and an enrollment call has been 
made into IVRS.  The enrollment date is to be documented in the subject’s medical 
record and on the enrollment electronic case report form (eCRF).

IC chemotherapy in a 1:1 ratio as assigned by the IVRS in an open-label manner.  The 
randomization will be performed by IVRS.  To randomize a subject, an authorized site 
representative will make the randomization call to the IVRS to assign a randomization 
number to the subject.  The randomization call to the IVRS is accomplished by entering 
the pertinent information detailed in the IVRS user manual.  The following information 
will be entered into IVRS for stratification: 
• 
Response to S1 (PMR vs NMR/PMD) 
• 
S1 chemotherapy (ie, Cytarabine [Ara-C] administered in S1 Yes/No) 
• 
PMBCL and B-cell lymphoma, unclassifiable, with features intermediate between 
DLBCL and classical Hodgkin lymphoma vs all other histologies of aggressive 
B-cell lymphoma 
Once data have been entered into the IVRS a confirmation fax or email will be sent to 
the site to verify that the correct information has been entered.  The site representative 
will receive a single, unique randomization number for each phase 3 subject and the 
randomization treatment assigned.  A phase 3 subject will be considered enrolled and 
randomized into the study when the investigator confirms that the subject has met all 
eligibility criteria and a randomization number is assigned.  The randomization date and 
randomization number are to be documented in the subject’s medical record and on the 
enrollment eCRF.  
Subjects should initiate their IVRS-assigned protocol required therapy within 3 days of 
enrollment confirmation for phase 2 and phase 3.

TREATMENT PROCEDURES 
6.1 
Classification of Product(s) and/or Medical Device(s) 
The Amgen Investigational Product (IP) used in this study is blinatumomab, and 
non-Amgen non-IP is IC chemotherapy. 
The Investigational Product Instruction Manual (IPIM), a document external to this 
protocol, contains detailed information regarding the storage, preparation, destruction, 
and administration of blinatumomab. 
Other protocol-mandated medication (eg, dexamethasone used for pre-dose treatment 
or for treatment of adverse events) are commercially available and are not provided or 
reimbursed by Amgen (except if required by local regulation).  The investigator will be 
responsible for obtaining supplies of these protocol-specified therapies.

6.2 
Investigational Product: Blinatumomab 
Blinatumomab will be manufactured and packaged by Amgen and distributed using 
Amgen clinical study drug distribution procedures. 
Blinatumomab will be supplied as single-use glass injection vials as a sterile, 
preservative-free, white to off-white, lyophilized powder for reconstitution and 
administration by intravenous (IV) infusion.  Each vial contains blinatumomab with 
additional excipients and buffers including citric acid monohydrate, trehalose dihydrate, 
lysine hydrochloride and polysorbate 80, pH 7. 
To prepare blinatumomab for IV infusion, the lyophilized powder is reconstituted with 
sterile water for injection.  The reconstituted solution is added to an infusion bag 
containing 0.9% NaCl and a product-specific stabilizer (IV Solution Stabilizer).  The 
IV solution stabilizer functions to prevent adsorption of blinatumomab to surfaces of the 
infusion components.  The IV Solution Stabilizer is supplied in a single-use glass 
injection vials as a sterile, preservative-free, clear, colorless-to-slightly-yellow liquid 
concentrate. 
Sterile water for injection and supplies required for reconstitution and injection of 
blinatumomab will not be provided to clinical sites. 
For information surrounding the use of a continuous infusion pump, refer to Section 6.7. 
6.2.1 
Dosage, Administration, and Schedule 
Blinatumomab will be administered by continuous IV infusion. 
A cycle of blinatumomab is 70 days and includes treatment 56 days of treatment, 
followed by a 14-day treatment-free interval.  The initial blinatumomab dose is 9 µg/day, 
and is escalated stepwise to 28 µg/day on day 8 and then 112 µg /day on day 15 until 
the completion of therapy, barring any dose modifications.  Optional Cycle 
2 blinatumomab consists of a 28 day cycle of blinatumomab continuous infusion 
administered 7 days at 9 µg/day, 7 days at 28 µg/day, and 14 days at 112 µg/day.  The 
dosing schedule is described in the study schema in Figure 1 for phase 2 and Figure 2 
for phase 3. 
The dose, start and stop date/time, and lot number of the protocol-specified therapy are 
to be recorded on each subject’s eCRF.  
Response should be assessed 14 (+ 3) days after completion of blinatumomab infusion. 
Chemotherapy should not be administered within the 14-day treatment-free interval

unless clinical evidence of disease progression has occurred and therapy is indicated. 
Uniform adherence to that timeline is optimal for interpretation of results.  Subjects 
receiving additional chemotherapy prior to the response assessment will be scored as 
nonresponders.   
6.2.1.1 
Inpatient Dosing 
Subjects should be monitored in a hospital for a minimum of 72 hours following initiation 
of therapy and for a minimum of 48 hours at each step-dose increase because of the 
potential adverse events associated with T-cell redistribution and potential cytokine 
release effects triggered by the administration of blinatumomab.  Nurses/physicians 
trained in emergency medicine should be available for immediate intervention in case of 
complications.  See Section 6.2.2.1 regarding monitoring following dose interruptions. 
6.2.1.2 
Outpatient Dosing  
After a subject meets the minimum criteria for inpatient administration and monitoring as 
described in Section 6.2.1.1, and if a subject is deemed stable by the investigator, 
continuation of blinatumomab infusion may continue as an outpatient.  See 
Section 6.2.2.1 regarding monitoring following dose interruptions. 
In the outpatient setting, either the subject will return to the study center for changes of 
infusion bags or the subject will be visited by a well-trained ambulant/home care service 
provider at specific intervals to change the infusion bag.  The subject and the 
ambulant/home care provider will be trained and will receive written instructions for 
storage of the IV bags.  
For the ambulant/home care provider, study-specific requirements and recording of 
source documentation must be completed before any study-related tasks are started.  A 
comprehensive list of all home care services, including but not limited to the storage, 
handling, and administration of blinatumomab as well as mandatory procedural and data 
collection requirements will be separately provided in a home health care manual.  
Following each visit, this information will be documented on the ambulant/home care 
services visit worksheet and forwarded to the investigator.  
In case of any adverse event in the outpatient setting, the ambulant/home care provider 
should directly contact the investigator at the study center for further management.  Any 
unexpected or unusual events as well as any deviations will be communicated promptly 
to the investigator.  The ambulant/home care professionals provide 24 hour emergency 
on-call service.

In addition, the subject will visit the study center for the examinations according to the 
Schedule of Assessments (Table 5 to Table 9). 
6.2.1.3 
Overdose 
The effects of overdose of this product are not known.  The daily blinatumomab dose 
may be up to 10% lower or higher in order to account for possible pump inaccuracies.  A 
dose of up to 10% higher than the intended dose may not require specific intervention.  
In case of overdose or medication error, the infusion should be immediately stopped.  
Consultation with the Amgen medical monitor is strongly recommended for prompt 
reporting of clinically apparent or laboratory adverse events possibly related to 
overdosage.  Consultation with the Amgen medical monitor is also strongly 
recommended even if there are no adverse events, in order to discuss the minimal 
duration of dose interruption.  If the overdose results in clinically apparent or 
symptomatic adverse events or additional adverse events, the subject should be 
followed carefully until all signs of toxicity are resolved and the adverse event/s should 
be recorded/reported per Section 9.  Resumption of blinatumomab should adhere to the 
guidelines in Section 6.2.2. 
6.2.2 
Dosage Adjustments, Delays, Rules for Withholding or Restarting, 
Permanent Discontinuation  
6.2.2.1 
Infusion Interruption Due to Technical/Logistical Reasons 
The administration of blinatumomab should not be interrupted, if possible.  In case of 
infusion interruption due to any technical or logistic reason, the interruption should be as 
short as possible and the infusion continued at the earliest time possible.  Every 
interruption longer than 1 hour should be documented.  
If the interruption is longer than 4 hours, re-start of the infusion should be performed in 
the hospital under the supervision of the investigator.  Administration of dexamethasone 
premedication prior to resumption of blinatumomab infusion after a treatment interruption 
of more than 4 hours is described in Section 6.4. 
The reason for dose change of blinatumomab is to be recorded on each subject’s eCRF. 
6.2.2.2 
Infusion Interruption/Dose Modifications due to Adverse Events 
Infusion interruptions and dose modifications of blinatumomab due to adverse events 
are detailed in Table 2.  Infusions will be resumed according to instructions in Table 2 in 
order to complete the full treatment cycle, excluding the duration of treatment 
interruption (56 days blinatumomab in cycle 1, 28 days blinatumomab in optional 
cycle 2).

not limited to: 
• 
Hepatobiliary tract disease 
• 
Viral hepatitis (eg, Hepatitis A/B/C/D/E, Epstein-Barr Virus, cytomegalovirus, Herpes 
Simplex Virus, Varicella, toxoplasmosis, and Parvovirus) 
• 
Right sided heart failure, hypotension or any cause of hypoxia to the liver causing 
ischemia. 
• 
Exposure to hepatotoxic agents/drugs or hepatotoxins, including herbal and dietary 
supplements, plants and mushrooms 
• 
Heritable disorders causing impaired glucuronidation (eg, Gilbert’s Syndrome, 
Crigler-Najjar syndrome) and drugs that inhibit bilirubin glucuronidation (eg, indinavir, 
atazanavir) 
• 
Alpha-one antitrypsin deficiency 
• 
Alcoholic hepatitis 
• 
Autoimmune hepatitis 
• 
Wilson’s disease and hemochromatosis 
• 
Nonalcoholic Fatty Liver Disease including Steatohepatitis 
•

Following the safety follow-up period, radiation administered will also be captured on a 
designated eCRF.  
The following should be recorded: medication name, indication, dose, route, frequency, 
start date, and stop date.  If changes occur during the study period, documentation of 
drug dosage, frequency, route, and date may also be included on the eCRF. 
6.7 
Medical Devices 
Blinatumomab must be administered using infusion pumps approved for use by the 
appropriate regulatory authorities for the country in which the subject is undergoing 
treatment, in both the inpatient and outpatient setting. 
Blinatumomab infusion for solution will be prepared in bags for IV infusion and delivered 
through infusion lines that are both compatible with the IP as described in the IPIM.  The 
blinatumomab final solution for infusion should not come into contact with the pump at 
any time. 
Additional details for the use of the above mentioned medical devices and specific set of 
device specifications are provided in the IPIM. 
Other non-investigational medical devices may be used in the conduct of this study as 
part of standard care.  These other medical devices, (eg, syringes, sterile needles, 
alcohol prep pads) that are commercially available are not usually provided or 
reimbursed by Amgen (except, for example, if required by local regulation).  The 
investigator will be responsible for obtaining supplies of these devices.  
6.8 
Product Complaints 
A product complaint is any written, electronic or oral communication that alleges 
deficiencies related to the identity, quality, durability, reliability, safety, effectiveness, or 
performance of a drug(s) or device(s) after it is released for distribution to market or

material.  
This includes any drug(s), device(s) or combination product(s) provisioned and/or 
repackaged /modified by Amgen.  Drug(s) or device(s) includes IP.  
Any product complaint(s) associated with an IP or non-IP(s) or device(s) supplied by 
Amgen are to be reported according to the instructions provided in the IPIM. 
6.9 
Excluded Treatments, Medical Devices, and/or Procedures During 
Screening and Treatment Periods 
Subjects are prohibited from receiving the following therapies during the Screening and 
Treatment Phase of this study: 
• 
Any anti-tumor therapy other than protocol specified therapies: 
• 
Radiation therapy. Note that radiotherapy to previously bulky sites of disease that 
upon response assessment, remains metabolically inactive (Deauville ≤ 4) will not 
be counted as an event. Intrathecal chemotherapy may be administered if the 
investigator deems the subject to be at high risk of CNS relapse. Evidence of CNS 
disease will be reported as relapse or progression. 
• 
Immunotherapy other than blinatumomab 
• 
Chronic systemic (> 7 days) high-dose corticosteroid therapy (dexamethasone 
> 24 mg/day or equivalent) 
• 
Any other immunosuppressive therapies (except for transient use of corticosteroids 
for ≤ 7 days) 
• 
Any other investigational agent 
Following last response assessment and prior to trial enrollment, subjects are prohibited 
from receiving additional chemotherapy. 
The Exclusion Criteria in Section 4.1.2 describe other medications that are prohibited in 
this study. 
6.10 
Contraceptive Requirements 
6.10.1 
Female Subjects  
Female subjects of childbearing potential must agree to practice true sexual abstinence 
(refrain from heterosexual intercourse) or use an effective method of contraception 
during treatment and for an additional 48 hours after the last dose of protocol-required 
therapies.  
Acceptable methods of effective contraception include: Hormonal (combined estrogen 
and progestogen or progesterone-only hormonal contraception given via oral, 
intravaginal, transdermal, injectable, or implantable route); Intrauterine device;

Intrauterine hormonal-releasing system; bilateral tubal occlusion/ligation; vasectomized 
partner (provided that partner is the sole sexual partner of the female participant who is 
of childbearing potential and that the vasectomized partner has received medical 
assessment of the surgical success); 2 barrier methods (1 by each partner) and the 
female partner must use spermicide (if spermicide is commercially available) with the 
barrier method the male must use a condom (latex or other synthetic material) and the 
female may select either a diaphragm, cervical cap or contraceptive sponge. A female 
condom is not an option because there is a risk of tearing when both partners use a 
condom.  The reliability of true sexual abstinence must be evaluated by the investigator 
and be the preferred and usual lifestyle of the subject.  
If a female subject is suspected of being pregnant, the protocol-required therapies must 
be stopped immediately and may not be resumed until absence of pregnancy has been 
medically confirmed.  
Females not of childbearing potential are defined as: Any female who is has had a 
hysterectomy, OR bilateral salpingectomy, OR bilateral oophorectomy, OR are 
post-menopausal. 
A postmenopausal state is defined as no menses for 12 months without an alternative 
medical cause.  (A high follicle stimulating hormone [FSH] level in the postmenopausal 
range may be used to confirm a postmenopausal state in women not using hormonal 
contraception or hormonal replacement therapy [HRT].  However, in the absence of 
12 months of amenorrhea, a single FSH measurement is insufficient). 
Females on HRT and whose menopausal status is in doubt will be required to use one of 
the non-hormonal highly effective contraception methods if they wish to continue their 
HRT during the study.  Otherwise, they must discontinue HRT to allow confirmation of 
postmenopausal status before study enrollment. 
Female subjects of childbearing potential must agree to practice sexual abstinence or 
use an acceptable method of effective contraception during the treatment and for an 
additional 48 hours after the last dose of blinatumomab. 
Acceptable methods of contraception include:  
• 
Combined (estrogen and progestogen) or Progestogen-only hormonal methods 
given via oral, intravaginal, transdermal, injectable, or implantable route) 
• 
Intrauterine device  
• 
Intrauterine hormonal-releasing system

• 
Bilateral tubal ligation/occlusion 
• 
Vasectomized partner (Provided that partner is the sole sexual partner of the 
female subject of childbearing potential and that the vasectomized partner has 
received medical assessment of the surgical success) 
• 
Sexual abstinence (Defined as refraining from heterosexual intercourse during 
the entire period of risk associated with the study treatments. The reliability of 
sexual abstinence must be evaluated in relation to the duration of the trial and 
the preferred and usual lifestyle of the subject.) 
• 
Double barrier method: the male uses a condom and the female may choose 
either a cervical cap, diaphragm, or contraceptive sponge with spermicide 
(A female condom is not an option due to the risk of tearing when both partners 
use a condom.) 
Additional medications given during treatment with blinatumomab may alter the 
contraceptive requirements.  These additional medications may require female subjects 
use highly effective methods of contraception and for an increased length of time.  In 
addition, male subjects may also be required to use contraception.  The investigator is to 
discuss these contraceptive changes with the subject. 
6.10.2 
Male Subjects 
Male subjects are not required to use birth control during treatment with blinatumomab.  
However, the subject should let his female partner know he is in the study. 
6.10.3 
Unacceptable Methods of Birth Control for Female Subjects 
Birth control methods that are considered unacceptable in clinical trials include: periodic 
abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus 
interruptus), spermicides only, and lactational amenorrhoea method. 
7. 
STUDY PROCEDURES 
Screening assessments and study procedures outlined in this section and in Table 5, 
Table 6, Table 7, Table 8, and Table 9 will be performed after obtaining a signed ICF. 
It is very important to attempt to perform study procedures and obtain samples at the 
precise timepoints stipulated below.  When it is not possible to perform the study visit at 
the exact timepoint, the visit may be performed within the acceptable visit window as 
defined in the visit-specific section below. 
Any missed visits, tests not done, or examinations that are not conducted must be 
reported as such on the eCRFs.  Subsequent study visits should resume on the original 
schedule.  Missed assessments at prior visits should not be duplicated at subsequent 
visits.

7.2 
General Study Procedures  
The procedures performed and timing of each study visit are outlined in the Schedule of 
Assessments (Table 5 to Table 9). It is very important to attempt to perform study 
procedures and obtain samples at the precise timepoints stipulated in the Schedule of 
Assessments (Table 5 to Table 9).  When it is not possible to perform the study visit at 
the exact timepoint, the visit may be performed within the acceptable visit windows if 
applicable.  Any missed visits, tests not done, or examinations that are not conducted 
must be reported as such on the eCRFs.  Subsequent study visits should resume on the 
original schedule.  Missed assessments at prior visits should not be duplicated at 
subsequent visits. 
Details regarding each type of procedure are provided in subsequent sub-sections. 
Refer to the applicable supplemental central laboratory, IVRS, IPIM, and study manuals 
for detailed collection and handling procedures.  Refer to the eCRF completion 
guidelines for data collection requirements and documentation of study 
assessments/procedures. 
Confirmation that the most current IRB/IEC-approved ICF has been signed should occur 
before any study-specific procedures are performed.  All subjects who are enrolled and 
receive blinatumomab or undergo study-specific procedures should be reconsented with 
any updated versions of IRB/IEC-approved ICFs during study participation as applicable 
and per institutional guidelines. 
7.2.1 
Screening, Enrollment and/or Randomization 
The screening period is up to 28-days.  Screening procedures are to be completed 
during the screening period at time points designated in the Schedule of Assessments 
(Table 5).  Informed consent must be obtained before completing any study-specific 
procedures.  Procedures that are part of standard of care are not considered 
study-specific procedures and may be performed before the informed consent and used 
to determine eligibility (as described in Section 4.1), but must be done within the 
timeframe as specified in the Schedule of Assessments (Table 5).  Randomization is 
described in Section 5.1.  
After written informed consent has been obtained, subjects will be screened to assess 
eligibility for study participation.  If a subject has not met all eligibility criteria at the end of 
the 28-day window, the subject will be registered as a screen failure.  Subjects who 
screen fail may be eligible to rescreen 1 additional time.

All screening procedures must be performed within 28 days of day 1 (ie, 28 days of the 
start of treatment with study drug), unless otherwise noted.  Subjects who meet the 
inclusion and exclusion criteria will be eligible to be enrolled in the study.  See 
Section 6.9 regarding treatments prohibited during screening.  
7.2.2 
Rescreening 
Subjects who are unable to complete or meet eligibility at the initial screening will be 
permitted to rescreen 1 time, provided study recruitment has not closed.  Re-screen 
subjects must first be registered as screen failed in IVRS and subsequently registered as 
re-screened.  Subjects will retain the same subject identification number assigned at the 
original screening.  Upon signing a new ICF, a new 28-day screening window will begin.  
Procedures completed during prior screening may be included in the rescreening 
eligibility criteria provided that they occur within the timeframe as specified in the 
schedule of assessments. 
7.2.3 
Treatment 
Subjects satisfying eligibility requirements will be enrolled into the treatment period and 
should receive the first dose of blinatumomab or IC chemotherapy on day 1 of the study. 
Visits and procedures will occur per the Schedule of Assessments (Table 6, Table 7, and 
Table 8) during the treatment period. 
7.2.4 
Safety Follow-up Visit(s) 
For phase 2 and phase 3, all subjects, including subjects who withdraw from treatment 
early, will complete a safety follow-up visit approximately 30 (± 3) days after their last 
dose of blinatumomab or 30 (± 3) days or after the last day of the last cycle of IC 
chemotherapy.  In the event that a planned cycle of therapy is delayed beyond 30 days, 
then the safety follow-up may be delayed without a protocol deviation.  However, in the 
event that therapy is not resumed, the subject should be seen for safety follow-up as 
soon as possible.  For subjects proceeding to HSCT, the safety follow-up visit must be 
conducted before the initiation of the transplant conditioning regimen.  
If a subject starts a new anti-lymphoma treatment within 30 (± 3) days of their last dose 
of protocol-assigned therapy, a safety follow-up visit should be conducted immediately 
prior to starting any new treatment, including HSCT conditioning regimens. 
The procedures performed at the safety follow-up visit are listed in Table 9 will be 
performed.

7.2.5 
Mobilization 
Suitability for HSC mobilization is determined by the investigator.  For those subjects 
who have received blinatumomab and who have not undergone prior HSC mobilization, 
HSC mobilization may commence after PET/CT restaging.  Mobilization should be with 
colony stimulating factors (ie G-CSF or GM-CSF alone) and should not be preceded by 
chemotherapy (chemomobilization) or done in planned conjunction with another 
mobilizing agent, such as plerixafor.  As an example, G-CSF may be administered at 
10 µg/kg/day for at least 5 days until the completion of apheresis.  The target cell dose is 
dictated by institutional standards, but should be no less than 2 x 106 CD34+ cells/kg.  
Failure to achieve that dose will be designated as not successful on the appropriate 
eCRF. 
For subjects randomized to IC S2 in phase 3, the timing of mobilization is determined 
according to the S2 protocol chosen by the investigator.  Additional chemotherapy or 
planned plerixafor should not be used in the initial mobilization attempt. 
Leukapheresis may commence according to local standards.  If peripheral blood 
leukocyte and/or CD34+ cell counts are insufficient to initiate leukapheresis, subjects 
may receive plerixafor in the initial mobilization or undergo other rescue mobilization, 
including chemomobilization or bone marrow harvest.  Mobilization that requires 
plerixafor or additional chemotherapy will be designated as not successful on the 
appropriate eCRF. 
7.2.6 
HSCT 
Subjects may be referred for HSCT after primary endpoint assessment at the discretion 
of the treating investigator, regardless of response.  Hematopoietic stem cell transplant 
Conditioning Status eCRF must be completed for all subjects to indicate whether an 
HSCT conditioning regimen was initiated within 30 days of first response assessment.  
Transplant types (autologous vs allogeneic), conditioning regimens, etc. are at the 
discretion of the investigator or site.  
Approximately 100 days after HSCT, the center will complete an HSCT summary 
document and/or the appropriate eCRF.  For subjects receiving autologous HSCT, about 
the following information will be collected: 
• 
Conditioning regimens 
• 
Number of cells infused (CD34+/kg) on day 0 
• 
Date of neutrophil engraftment (first day that ANC > 0.5 x 109/L for 3 consecutive 
days)

• 
Date of platelet engraftment (first day that platelets > 20 x 109/ L) 
• 
Complications of autologous HSCT 
For subjects receiving allogeneic HSCT, the HSCT summary document will include 
information about: 
• 
Conditioning regimen, including intensity (myeloablative or reduced intensity) 
• 
Donor (matched sibling, mismatched related, matched unrelated, mismatched 
unrelated, haploidentical) 
• 
# alleles matching/# alleles typed 
• 
Cell source (peripheral blood, bone marrow, umbilical cord blood) 
• 
Primary graft-versus-host disease prophylaxis 
• 
Maximum grade of acute graft-versus-host disease 
• 
Other treatment related complications  
7.2.7 
Long-term Follow-up 
For both phase 2 and phase 3, follow-up visits for assessment of relapse, transplant 
status, and survival will take place every 3 months (calculated from the safety follow up 
visit) until completion of a 2-year period after treatment, thereafter follow-up for 
survival and transplant status will be completed in person or by telephone call every 
6 months (± 28 days) until study completion.  Study completion will occur once 
236 death events for phase 3 subjects have occurred or 12 months since last subject in 
phase 3 is randomized if 236th death in phase 3 subjects is not observed.  If the study 
will not continue for the phase 3 portion, study completion will occur when the 
last phase 2 subject has had the opportunity to complete their 2 year follow-up 
visit after treatment. 
Should a subject fail to return to the clinic for a scheduled protocol visit or neglect 
to participate in a scheduled follow up telephone call, sites will need to make 
3 attempts to contact subjects by a combination of telephone and mail.  Sites 
must document all 3 attempts to contact the subject.  If a subject does not 
respond within 1 month after the third contact, the subject will be considered lost 
to follow-up.The procedures and tests listed in Table 9 will be performed during the 
long-term follow up.  Subjects will allow Amgen continued access to medical records so 
that information related to subjects’ health condition, including disease status and overall 
survival, may be obtained.

7.2.8 
End of Study 
Study completion will occur once 236 death events for phase 3 subjects have occurred 
or 12 months after the last subject in phase 3 is randomized if 236th death in 
phase 3 subjects is not observed. 
If the study will not continue for the phase 3 portion, the study will conclude when 
all phase 2 subjects have had the opportunity to complete long term follow-up as 
described above.  
7.2.9 
Early Termination Visit 
Subjects (or a legally acceptable representative) can decline to continue receiving 
protocol-specified therapies or procedures at any time during the study but continue 
participation in the study.  Reasons for removal of a subject from treatment or study are 
discussed in Section 8.3. 
If a subject discontinues protocol-specified therapies or procedures, the Investigator is to 
discuss with the subject the appropriate processes for discontinuation from 
protocol-specified therapies and must discuss with the subject the options for 
continuation of the Schedule of Assessments and collection of data, including endpoints 
and adverse events.  The Investigator must document the change to the Schedule of 
Assessments (Table 5 to Table 9) and the level of follow-up that is agreed to by the 
subject (eg, in person, by telephone/mail, through family/friends, in 
correspondence/communication with other physicians, and from review of the medical 
records). 
7.3 
Description of Study Procedures 
The following study procedures will be conducted at the time points outlined in the 
Schedule of Assessments (Table 5 to Table 9). 
7.3.1 
Informed Consent 
All subjects or their legally acceptable representative (ie, legal guardian) must sign and 
date the most current IRB/EC approved ICF.  Confirmation that the ICF has been signed 
should occur before any study specific procedures are performed.  All subjects who are 
randomized and receive protocol-specified therapy or specified treatment should be 
re-consented with any updated versions of IRB/EC approved informed consents during 
study participation as applicable and per institutional guidelines.

7.3.2 
Demographics 
Demographic data collection including sex, age, race, and ethnicity will be collected in 
order to study their possible association with subject safety and treatment effectiveness.  
Additionally, demographic data will be used to study the impact on biomarker variability 
and PK of the protocol-required therapies. 
7.3.3 
Medical History 
The investigator or designee will collect a complete medical and surgical history that 
started 5 years prior to screening through the time of first dose.  Medical history will 
include information on the subject’s concurrent medical conditions.  In addition, 
lymphoma history must date back to the initial diagnosis of B-NHL.  
In addition to the medical history noted above, all history related to the subject’s 
diagnosis of aggressive B-NHL (eg, date of initial diagnosis, international prognostic 
index and additional risk factors at diagnosis, stage at diagnosis, COO at any timepoint if 
available [immunohistochemistry pattern, GEP/other], BCL-2 [Fluorescent in-situ 
hybridization [FISH]: translocation, immunohistochemistry expression levels], c-myc 
[FISH: translocation, immunohistochemistry expression levels]) will be recorded. 
7.3.4 
Prior Therapies 
For initial chemotherapy regimen (eg R-CHOP-21, R-CHOP-14, R-EPOCH), specify 
number of cycles, indicate if dose deviations for named regimen and specify justification 
(ie, cytopenias, organ toxicity) that prompted dose deviation, indicate if ongoing; if yes, 
then current Grade (CTCAE version 4.0); response assessment after completion of 
frontline chemotherapy (eg PMD/PD, NMR/SD, PMR, CMR); radiotherapy yes/no; if yes, 
sites and dose; and if relapsed, duration of time (months) between diagnosis and 
relapse. 
7.3.5 
ECOG Performance Status Assessment 
The subject’s performance status will be assessed using the ECOG performance status 
scale (see Appendix E). 
7.3.6 
Physical Measurements 
Height in centimeters and weight in kilograms should be measured without shoes.  
Height will only be performed at screening. 
7.3.7 
Vital Signs 
The following measurements for vital signs must be performed: systolic/diastolic blood 
pressure, heart rate, respiratory rate, and temperature.  Subject must be in a supine

position in a rested and calm state for at least 5 minutes before blood pressure 
assessments are conducted.  If the subject is unable to be in the supine position, the 
subject should be in most recumbent position possible.  The position selected for a 
subject should be the same throughout the study and documented on the vital signs 
eCRF.  The anatomic temperature assessment location selected for a subject should 
be the same throughout the study and documented on the vital signs eCRF.  If 
abnormalities are found and they are considered an adverse event, record on the Event 
CRF. 
7.3.8 
Physical Examination  
Physical examination will be completed as per standard of care.  Physical examination 
findings at screening will include medical and surgical history and will be recorded on the 
medical history eCRF.  Any new findings on physical examination during the course of 
the study will be considered adverse events. 
7.3.9 
Neurological Examination 
A baseline neurological examination will be performed according to institutional 
standards.  Subjects will be specifically queried for neurological symptoms observed in 
the interval since the last extended neurological examination.  Abnormalities of the 
following should be recorded: level of consciousness, orientation, vision, cranial nerves 
and brain stem functions, pyramidal and extra pyramidal motory system, reflexes, 
muscle tone and trophic findings, coordination, sensory system, neuropsychological 
findings (eg, speech, cognition and emotion).  Neurologic examination findings should be 
recorded on the appropriate eCRF (eg, medical history, event). 
7.3.10 
Electrocardiogram  
Standard of care electrocardiogram (ECG) will be performed.  Subject must be in supine 
position in a rested and calm state for at least 5 minutes before ECG assessment is 
conducted.  If the subject is unable to be in the supine position, the subject should be in 
most recumbent position as possible. 
The ECG must include the following measurements: heart rate, QRS, QT, QTc, and PR 
intervals. 
The principal investigator or designated center physician, will review all ECGs.  Once 
signed, the original ECG tracing will be retained with the subject’s source documents.  At 
the request of the sponsor, a copy of the original ECG will be made available to Amgen.  
Findings should be recorded on the ECG eCRF.

7.3.11 
Response Assessment 
The Lugano Classification will be used to assess treatment response as described in 
Appendix D. 
7.3.12 
Clinical Tumor Assessment 
Clinical tumor assessments will be performed as indicated in the schedule of 
assessments and are based on changes in the size of previously abnormal lymph node 
groups or extranodal sites, or the appearance of new lesions suspected to represent 
lymphoma progression or relapse.  Findings will be recorded on the clinical tumor 
assessment eCRF. 
7.3.13 
Radiographic Assessment 
PET/CT scans with whole body images, from base of skull to mid-thigh, will be 
conducted.  Examinations should be consistent across all timepoints including: the 
amount of tracer, location of injection, arm location, and scan delay.  
The following data should be collected per center: standard procedures, height, weight, 
gender, administered dose, time between dose administration and imaging, blood 
glucose level, number of cycles of S1 chemotherapy, and time between blood glucose 
level sampling and tracer injection.  Additionally, the number of cycles of chemotherapy 
and date and the use of G-CSF/GM-CSF (dose and dates administered) should also be 
provided. 
PET images should be converted to standardized uptake values maps to support 
comparison across timepoints and to standardize viewing conditions CT anatomical 
coverage: chest, abdomen, and pelvis (and neck if not visualized with chest).  
If PET and CT are acquired on the same day, it is strongly recommended that PET is 
performed prior to the CT with IV contrast.  Refer to the imaging manual for additional 
details, including requirements for submission of pre-S1 scans. 
7.3.14 
Bone marrow biopsy 
Bone marrow evaluation (core biopsy with or without aspirate) should be performed if 
there has been previous histologic evidence of bone marrow involvement plus a 
negative or ambiguous PET/CT, or if bone marrow involvement is suspected with an 
ambiguous or negative PET/CT.  Refer to the Laboratory Manual for additional 
information.

EQ-5D (instrument holder The EuroQol Group) (Appendix F) and FACT-Lymphoma 
(instrument holder FACT-Lym) (Appendix G).  
7.3.17 
Vital Status 
Vital status must be obtained for all subjects within the limits of local law.  This includes 
subjects who may have discontinued study visits with or without withdrawing consent 
and should include interrogation of public databases, if necessary.  If the subject is 
deceased, the date and reported case of death should be obtained. 
7.4 
Laboratory Procedures 
All screening and on-study laboratory samples will be collected, processed and sent to 
the investigator local laboratory or central laboratory as applicable (Table 10).  Detailed 
instructions for sample collection, processing, and shipping are provided in the central 
laboratory manual and/or Amgen-provided training materials.  The date and time of 
sample collection will be recorded in the source documents at the site.  
Blood draws should not be done via central venous access.  Exception: If a permanent 
central line with more than 1 lumen is used, blood draws can be done via the lumen that 
is not used for drug administration.  The analytes for all laboratory tests used throughout 
this study are listed in Table 10.

Pharmacokinetic Samples 
All subjects randomized to blinatumomab will have PK samples assessed.  Blood 
samples for PK testing are to be collected at the timepoints noted in Table 6, for the 
measurement of PK concentrations. 
7.4.2 
Cell-Free CT-DNA 
At the screening timepoint, a diagnostic tumor specimen will be collected, and sections 
will be used to determine clonotypic sequences of rearranged antigen receptor genes 
and/or mutational status of specific genes.  Samples of peripheral blood will be collected 
for plasma separation and freezing at timepoints indicated in the Schedule of 
Assessments.  Frozen plasma will be shipped to a central laboratory for high throughput 
sequencing. 
7.4.3 
Serum Cytokines 
To monitor activation of immune effector cells, blood samples for measurement of 
peripheral blood cytokine levels will be taken at the timepoints shown in Table 7 for all 
subjects in phase 2 and subjects randomized to blinatumomab in phase 3.  The following 
cytokines will be assessed by cytometric bead array (CBA) technique: IL-2, IL-6, IL-10, 
TNFα and IFNγ. 
7.4.4 
Lymphocyte Subsets 
In subjects who receive blinatumomab to monitor changes in lymphocytes (B-cell and 
T-cell populations) and leukocyte populations (leukocytes, lymphocytes, monocytes, and 
granulocytes) in peripheral blood, samples will be collected before dexamethasone 
administration, after dexamethasone administration but before blinatumomab 
administration, and at additional timepoints as outlined in the Schedule of Assessments 
Table 6.  The frequent sample collection during the treatment period will help to better 
understand the mechanism of action of the T-cell response. 
7.4.5 
Antibody Testing Procedures 
Blood samples will be collected at time points as outlined in the Schedule of 
Assessments for the measurement of anti-blinatumomab antibodies.  Samples testing 
positive for binding antibodies may be further characterized for quantity/titer, isotype, 
affinity, in-vitro neutralizing activity and presence of immune complexes.  Additional 
blood samples may be obtained to rule out anti-drug antibodies during the study.  
Subjects who test positive for binding antibodies and have clinical sequelae that are 
considered potentially related to an anti-blinatumomab antibody response may also be 
asked to return for additional follow up testing.

7.5 
Biomarker Development 
Biomarkers are objectively measured and evaluated indicators of normal biologic 
processes, pathogenic processes, or pharmacologic responses to a therapeutic 
intervention.  In oncology, there is particular interest in the molecular changes underlying 
the oncogenic processes that may identify cancer subtypes, stage of disease, assess 
the amount of tumor growth, or predict disease progression, metastasis, and responses 
to IP or protocol-required therapies.  
Amgen may attempt to develop test(s) designed to identify subjects most likely to 
respond positively or negatively to blinatumomab using the blood and bone marrow 
samples collected as outlined in the Schedule of Assessments.  Biomarker development 
may be pursued by the use of advanced biochemical analyses such as proteomic 
methods, ribonucleic acid transcript profiling and DNA sequencing.  Refer to the 
laboratory manual for detailed collection and handling procedures for all biomarker 
development samples. 
7.6 
Optional Pharmacogenetic Studies 
If the subject consents to the optional pharmacogenetic portion of this study, DNA 
analyses may be performed.  A peripheral blood cell pellet will be collected at the time of 
plasma separation for genomic DNA isolation.  Frozen plasma and cell pellets will be 
shipped to a central laboratory for high throughput sequencing.  These optional 
pharmacogenetic analyses focus on inherited genetic variations to evaluate their 
possible correlation to the disease and/or responsiveness to the therapies used in this 
study.  Genomic DNA will be isolated from non-malignant as well as tumor tissue in 
order to determine if genetic polymorphisms in the tumor sample are tumor-associated 
or germline mutations.  At present, there is no plan to perform targeted analysis of 
non-tumor associated genes in order to identify predictors of efficacy, toxicity, or to 
understand drug metabolism.  No additional samples will be collected for 
pharmacogenetic studies.  
7.7 
Sample Storage and Destruction 
Any blood sample collected according to the Schedule of Assessments (Table 5 through 
Table 9) can be analyzed for any of the tests outlined in the protocol and for any tests 
necessary to minimize risks to study subjects.  This includes testing to ensure analytical 
methods produce reliable and valid data throughout the course of the study.  This can 
also include, but is not limited to, investigation of unexpected results, incurred sample 
reanalysis, and analyses for method transfer and comparability.

All samples and associated results will be coded prior to being shipped from the study 
center for analysis or storage.  Samples will be tracked using a unique identifier that is 
assigned to the samples for the study.  Results are stored in a secure database to 
ensure confidentiality.  
If informed consent is provided by the subject, Amgen can do additional testing on 
remaining samples (ie, residual and back-up) to investigate and better understand the 
disease under study, DLBCL, the dose response and/or prediction of response to 
blinatumomab, characterize antibody response, and characterize aspects of the 
molecule (eg, mechanism of action/target, metabolites).  Results from this analysis are 
to be documented and maintained, but are not necessarily reported as part of this study.  
Samples can be retained for up to 20 years.  
Since the evaluations are not expected to benefit the subject directly or to alter the 
treatment course, the results of biomarker development, or other exploratory studies are 
not placed in the subject’s medical record and are not to be made available to the 
subject, members of the family, the personal physician, or other third parties, except as 
specified in the informed consent. 
The subject retains the right to request that the sample material be destroyed by 
contacting the investigator.  Following the request from the subject, the investigator is to 
provide the sponsor with the required study and subject number so that any remaining 
samples (eg, blood, tumor) and any other components from the cells can be located and 
destroyed.  Samples will be destroyed once all protocol-defined procedures are 
completed.  However, information collected from samples prior to the request for 
destruction, will be retained by Amgen. 
The sponsor is the exclusive owner of any data, discoveries, or derivative materials from 
the sample materials and is responsible for the destruction of the sample(s) at the 
request of the subject through the investigator, at the end of the storage period, or as 
appropriate (eg, the scientific rationale for experimentation with a certain sample type no 
longer justifies keeping the sample).  If a commercial product is developed from this 
research project, the sponsor owns the commercial product.  The subject has no 
commercial rights to such product and has no commercial rights to the data, information, 
discoveries, or derivative materials gained or produced from the sample.  See 
Section 11.3 for subject confidentiality.

WITHDRAWAL FROM TREATMENT, PROCEDURES, AND STUDY 
8.1 
Subjects’ Decision to Withdraw 
Subjects have the right to withdraw from the study at any time and for any reason 
without prejudice to their future medical care by the physician or at the institution. 
Subjects (or a legally acceptable representative) can decline to continue receiving IP 
and/or other protocol-required therapies or procedures at any time during the study but 
continue participation in the study.  If this occurs, the investigator is to discuss with the 
subject the appropriate processes for discontinuation from IP, device or other 
protocol-required therapies and must discuss with the subject the options for 
continuation of the Schedule of Assessments (Table 5, Table 6, Table 7, Table 8, and 
Table 9) and collection of data, including endpoints, adverse events, disease related 
events, and device related events, as applicable.  All attempts should be made to follow 
subjects through safety follow-up.  The investigator must document the change to the 
Schedule of Assessments (Table 5, Table 6, Table 7, Table 8, and Table 9) and the level 
of follow-up that is agreed to by the subject (eg, in person, by telephone/mail, through 
family/friends, in correspondence/communication with other physicians, from review of 
the medical records).  
Withdrawal of consent for a study means that the subject does not wish to receive 
further protocol-required therapies or procedures, and the subject does not wish to or is 
unable to continue further study participation.  Subject data up to withdrawal of consent 
will be included in the analysis of the study, and where permitted, publically available 
data can be included after withdrawal of consent.  The investigator is to discuss with the 
subject appropriate procedures for withdrawal from the study.  
8.2 
Investigator or Sponsor Decision to Withdraw or Terminate 
Subjects’ Participation Prior to Study Completion 
The investigator and/or sponsor can decide to withdraw a subject(s) from IP, device, 
and/or other protocol-required therapies, protocol procedures, or the study as a whole at 
any time prior to study completion.  
Subjects may be eligible for continued treatment with Amgen IP(s) and/or other 
protocol-required therapies by a separate protocol or as provided for by the local 
country’s regulatory mechanism, based on parameters consistent with Section 12.1.

SAFETY DATA COLLECTION, RECORDING, AND REPORTING 
9.1 
Definition of Safety Events 
9.1.1 
Disease Related Events 
Disease Related Events are events (serious or non-serious) anticipated to occur in the 
study population due to the underlying disease, eg, disease progression.  Such events 
do not meet the definition of an adverse event unless assessed to be more severe than 
expected for the subject’s condition. 
Disease Related Events that do not qualify as Adverse Events or Serious Adverse 
Events:  
• 
An event which is part of the normal course of disease under study (eg, disease 
progression in oncology or hospitalization due to disease progression) is to be 
reported as a Disease Related Event.  
• 
Death due to the disease under study is to be recorded on the Event CRF.

Disease Related Events that would qualify as an Adverse Event or Serious Adverse 
Event: 
•
An event based on the underlying disease that is worse than expected as assessed
by the investigator for the subject’s condition or if the investigator believes there is a
causal relationship between the IP(s)/study treatment/protocol-required therapies
and disease worsening, this must be reported as an Adverse Event or Serious
Adverse Event.

9.1.2 
Adverse Events 
An adverse event is defined as any untoward medical occurrence in a clinical trial 
subject.  The event does not necessarily have a causal relationship with study treatment.  
The investigator is responsible for ensuring that any adverse events observed by the 
investigator or reported by the subject are recorded in the subject’s medical record.  
The definition of adverse events includes worsening of a pre-existing medical condition.  
Worsening indicates that the pre-existing medical condition or underlying disease 
(eg, diabetes, migraine headaches, gout) has increased in severity, frequency, and/or 
duration more than would be expected, and/or has an association with a significantly 
worse outcome than expected.  A pre-existing condition that has not worsened more 
than anticipated (ie, more than usual fluctuation of disease) during the study or involves 
an intervention such as elective cosmetic surgery or a medical procedure while on study, 
is not considered an adverse event.  
If the severity of an adverse event changes from the date of onset to the date of 
resolution, record as a single event with the worst severity on the Event eCRF.

For situations when an adverse event or serious adverse event is due to lymphoma 
report all known signs and symptoms.  Death due to disease progression in the absence 
of signs and symptoms should be reported as the primary tumor type (eg, R/R indolent 
NHL).  
Note: The term “disease progression” should not be used to describe the disease 
related event or adverse event.  
An adverse device effect is any adverse event related to the use of a medical device.  
Adverse device effects include adverse events resulting from insufficient or inadequate 
instructions for use, adverse events resulting from any malfunction of the device, or 
adverse events resulting from use error or from intentional misuse of the device. 
The investigator’s clinical judgment is used to determine whether a subject is to be 
removed from treatment due to an adverse event.  In the event a subject, or subject’s 
legally acceptable representative requests to withdraw from protocol-required therapies 
or the study due to an adverse event, refer to Section 8.1 for additional instructions on 
the procedures recommended for safe withdrawal from protocol-required therapies or 
the study.  
9.1.3 
Serious Adverse Events 
A serious adverse event is defined as an adverse event that meets at least 1 of the 
following serious criteria (unless it meets the definition of a Disease Related Event as 
defined in Section 9.1.1): 
• 
fatal 
• 
life threatening (places the subject at immediate risk of death) 
• 
requires in-patient hospitalization or prolongation of existing hospitalization 
• 
results in persistent or significant disability/incapacity 
• 
congenital anomaly/birth defect 
• 
other medically important serious event 
A disease related event blood and lymphatic system disorders or investigations are to be 
reported as a serious adverse event if: 
• 
the subject’s pre-existing condition becomes worse than what the investigator would 
consider typical for a patient with the same underlying condition, or 
• 
if the investigator believes a causal relationship exists between the investigational 
medicinal product(s)/protocol-required therapies and the event,  
• 
and the event meets at least 1 of the serious criteria.

An adverse event would meet the criterion of “requires hospitalization”, if the event 
necessitated an admission to a health care facility (eg, overnight stay).  
If an investigator considers an event to be clinically important, but it does not meet any 
of the serious criteria, the event could be classified as a serious adverse event under the 
criterion of “other medically important serious event”.  Examples of such events could 
include allergic bronchospasm, convulsions, blood dyscrasias, DILI (see Appendix A for 
drug-induced liver injury reporting criteria), or events that necessitate an emergency 
room visit, outpatient surgery, or urgent intervention. 
If the criteria for grade 4 in the CTCAE grading scale for laboratory event differs from 
the regulatory criteria for serious adverse events, it is left to the investigator’s judgement 
whether to report these grade 4 abnormalities as serious adverse events. 
9.2 
Safety Event Reporting Procedures  
9.2.1 
Reporting Procedures for Disease Related Events 
The investigator is responsible for ensuring that all Disease Related Events observed by 
the investigator or reported by the subject that occur after the first dose of investigational 
medicinal product(s)/study treatment/protocol-required therapies through the safety 
follow-up visit are recorded on the Event CRF as a Disease Related Event.  
Disease Related Events assessed by the investigator to be more severe than expected 
and/or related to the investigational medicinal product(s)/study 
treatment/protocol-required therapies, and determined to be serious, must be recorded 
on the Event CRF as Serious Adverse Events.  
Additionally, the investigator is required to report a fatal Disease Related Event on the 
Event CRF.  
9.2.2 
Adverse Events 
9.2.2.1 
Reporting Procedures for Adverse Events That Do Not Meet Serious 
Criteria 
The investigator is responsible for ensuring that all adverse events observed by the 
investigator or reported by the subject that occur from the first dose of IP through the 
safety follow-up visit are reported using the Event CRF.  Adverse events considered by 
the investigator to be possibly related to blinatumomab will be reported from the 
beginning of transplant conditioning during the long-term follow up until completion of a 
2-year period after treatment.

The investigator must assign the following adverse event attributes: 
• 
Adverse event diagnosis or syndrome(s), if known (if not known, signs or symptoms), 
• 
Dates of onset and resolution (if resolved), 
• 
Severity [and/or toxicity per protocol], 
• 
Assessment of relatedness to blinatumomab or protocol required medication or 
medical device, and 
• 
Action taken. 
The adverse event grading scale used will be the CTCAE.  The grading scale used in 
this study is described in Appendix A.  
The investigator must assess whether the adverse event is possibly related to 
blinatumomab.  This relationship is indicated by a “yes” or “no” response to the question: 
Is there a reasonable possibility that the event may have been caused by the 
investigational medicinal product?  
The investigator must assess whether the adverse event is possibly related to any 
study-mandated activity (eg, protocol-required therapies).  This relationship is indicated 
by a “yes” or “no” response to the question: “Is there a reasonable possibility that the 
event may have been caused by a study activity (eg, protocol-required therapies), and/or 
procedure”?   
The investigator is responsible for reviewing laboratory test results and determining 
whether an abnormal value in an individual study subject represents a change from the 
subject’s baseline values.  All grade 3 and grade 4 laboratory values should be recorded 
as adverse events.  In addition, if signs or symptoms are associated with a laboratory 
abnormality, the signs/symptoms and the laboratory abnormality should all be recorded 
as adverse events.  The laboratory abnormality and any signs/symptoms should be 
graded according to their own CTCAE criteria. 
The Investigator is expected to follow reported adverse events until stabilization or 
reversibility.  
9.2.2.2 
Reporting Procedures for Serious Adverse Events 
The investigator is responsible for ensuring that all serious adverse events observed by 
the investigator or reported by the subject that occur after signing of the informed 
consent through safety follow-up are recorded in the subject’s medical record and are 
submitted to Amgen.  In addition, blinatumomab related serious adverse events will be 
reported during the long term follow-up.  All serious adverse events must be submitted to 
Amgen within 24 hours following the investigator’s knowledge of the event via the Event 
CRF.

If the electronic data capture (EDC) system is unavailable to the site staff to report the 
serious adverse event, the information is to be reported to Amgen via an electronic 
Serious Adverse Event Contingency Report Form within 24 hours of the investigator’s 
knowledge of the event.  See Appendix B for a sample of the Serious Adverse Event 
Worksheet /electronic Serious Adverse Event Contingency Report Form.  For EDC 
studies where the first notification of a Serious Adverse Event is reported to Amgen via 
the eSerious Adverse Event Contingency Report Form, the data must be entered into 
the EDC system when the system is again available. 
The investigator must assess whether the serious adverse event is possibly related to 
blinatumomab and/or other protocol-required therapies.  This relationship is indicated by 
a “yes” or “no” response to the question: Is there a reasonable possibility that the event 
may have been caused by the IP? 
The investigator is expected to follow reported serious adverse events until stabilization 
or reversibility.  
New information relating to a previously reported serious adverse event must be 
submitted to Amgen.  All new information for serious adverse events must be sent to 
Amgen within 24 hours following knowledge of the new information.  If specifically 
requested, the investigator may need to provide additional follow-up information, such as 
discharge summaries, medical records, or extracts from the medical records.  
Information provided about the serious adverse event must be consistent with that 
recorded on the Event CRF. 
If a subject is permanently withdrawn from protocol-required therapies because of a 
serious adverse event, this information must be submitted to Amgen. 
Amgen will report serious adverse events and/or suspected unexpected serious adverse 
reactions as required to regulatory authorities, investigators/institutions, and IRBs/IECs 
in compliance with all reporting requirements according to local regulations and GCP.  
The investigator is to notify the appropriate IRB/IEC of serious adverse events occurring 
at the site and other adverse event reports received from Amgen, in accordance with 
local regulatory requirements and procedures. 
9.2.2.3 
Reporting Serious Adverse Events After the Protocol-required 
Reporting Period 
There is no requirement to monitor study subjects for serious adverse events following 
the protocol-required reporting period or after end of study.  However, these serious

adverse events can be reported to Amgen.  In some countries (eg, European Union 
member states), investigators are required to report serious adverse events that they 
become aware of after end of study.  If serious adverse events are reported, the 
investigator is to report them to Amgen within 24 hours following the investigator’s 
knowledge of the event. 
In addition to the attributes listed in Section 9.2.2.1, the investigator must also complete 
the serious adverse event section of the Event eCRF. 
Serious adverse events reported outside of the protocol-required reporting period will be 
captured within the safety database as clinical trial cases for the purposes of expedited 
reporting.  
9.2.2.4 
Serious Adverse Events That are not to be Reported by the 
Sponsors to Regulatory Agencies in an Expedited Manner  
Events which are morbidities associated in general with lymphoma and lymphoma 
therapy do not require expedited reporting: 
• Planned hospitalization
9.2.3 
Reporting of Delayed Time to HSCT for Subjects With PR/PMR At 
Baseline 
The investigator is responsible for reporting delays to HSCT in subject that meet the 
following criteria: 
PR/PMR at baseline per Lugano classification and  
Do not proceed to HSCT within 30 days of the first response assessment 
These events will be recorded in the CRF and must be submitted to Amgen with 
24 hours following the investigator’s knowledge of the event.  Refer to eCRF completion 
guidelines for specific reporting directions. 
9.3 
Pregnancy and Lactation Reporting 
If a female subject becomes pregnant, or a male subject fathers a child, while the 
subject is taking blinatumomab, report the pregnancy to Amgen Global Patient Safety as 
specified below. 
In addition to reporting any pregnancies occurring during the study, investigators should 
report pregnancies that occur 48 hours after the last dose of blinatumomab. 
The pregnancy should be reported to Amgen Global Patient Safety within 24 hours of 
the investigator’s knowledge of the event of a pregnancy.  Report a pregnancy on the

Pregnancy Notification Worksheet (Appendix C).  Amgen Global Patient Safety will 
follow-up with the investigator regarding additional information that may be requested.  
If a female subject becomes pregnant during the study, the investigator should attempt 
to obtain information regarding the birth outcome and health of the infant.  If a male 
subject's female partner becomes pregnant, the investigator should discuss obtaining 
information regarding the birth outcome and health of the infant from the pregnant 
partner.  
If the outcome of the pregnancy meets a criterion for immediate classification as a 
Serious Adverse Event (eg, female subject experiences a spontaneous abortion, 
stillbirth, or neonatal death or there is a fetal or neonatal congenital anomaly) the 
investigator will report the event as a Serious Adverse Event.  
If a female breastfeeds while taking protocol-required therapies report the lactation case 
to Amgen as specified below.  
In addition to reporting a lactation case during the study, investigators should report 
lactation cases that occur 48 hours after the last dose of protocol-required therapies.  
Any lactation case should be reported to Amgen Global Patient Safety within 24 hours of 
the investigator’s knowledge of event.  Report a lactation case on the Lactation 
Notification Worksheet (Appendix C).  Amgen Global Patient Safety will follow-up with 
the investigator regarding additional information that may be requested.

Handling of Missing and Incomplete Data  
Subjects missing post baseline disease assessments will be considered not to have 
achieved CMR. 
Subjects not experiencing events that of interest for time-to-event endpoints (eg, deaths 
for OS) will be censored according to rules to be detailed in the statistical analysis plan. 
10.2 
Sample Size Considerations 
10.2.1 
Phase 2  
The sample size for the phase 2 part of the study is determined by a 1-sample test of the 
rate of CMR during the first 12 weeks after initiation of blinatumomab.  With the 
1-sided type I error rate (α) set at 0.025, a null hypothesis response probability (π0) of 
15%, and an alternative response probability (π1) of 40%, a sample size of 36 subjects 
will provide 90% power to reject the null hypothesis that the response probability is no 
more than 15%.  Being able to make this determination will represent evidence of clinical 
activity and warrant advancement into the phase 3 part of the study. 
10.2.2 
Phase 3 
The primary endpoint is CMR.  A CMR rate of 22% in the IC arm vs. 40% in the 
blinatumomab arm is hypothesized.  The odds ratio of CMR rate will be tested at the 
1-sided significance level of 0.025. With these assumptions and a 1:1 randomization

ratio, a sample size of 296 subjects will provide 89% power.  The sample size is adjusted 
for 3 interim futility analyses when 25%, 50%, and 75% of the subjects have had the 
opportunity to complete the tumor assessment and 1 interim efficacy analysis when 
75% of the subjects have had the opportunity to complete the tumor assessment.  The 
interim futility boundaries will use a Lan-DeMets beta-spending approach to an 
O’Brien-Fleming boundary and the interim efficacy boundaries will use a Lan-DeMets 
alpha-spending approach to an O’Brien-Fleming boundary.  The details of these interim 
analyses are specified in the Section 10.4.1.  
Overall survival is a key secondary endpoint and the study is also powered for overall 
survival.  If the null hypothesis for the primary endpoint is rejected, then OS will also be 
tested at a 1-sided significance level of 0.025.  Assuming the true hazard ratio is 0.65 a 
final OS analysis after 236 death events will provide 90% power.  With a median survival 
time of 4.4 months in the IC arm vs. 6.7 months in blinatumomab arm, accrual rates of 
14.5 subjects per month, a 5% drop-out rate per year, and a targeted sample size of 
296 randomized subjects, it is estimated that the 236th event will occur within 26 months 
of the start of randomization. 
Sample size re-estimation will be allowed at an interim analysis (see Section 10.4.1). 
10.3 
Access to Individual Subject Treatment Assignments by Amgen or 
Designees 
Blinded individuals will not have access to unblinded information until the study is 
formally unblinded.  Unblinding and potentially unblinding information should not be 
distributed to the study team, investigators or subjects prior to the study being formally 
unblinded (eg, the formal unblinding may occur at the final analysis rather than during 
the primary analysis) except as specified (eg, Section 10.4.1 and Section 9.2.2.2).

Based on the conditional power at the third interim analysis of CMR and first interim 
analysis of OS, there will be a possibility to increase the sample size by at most 
50% using the method of Gao, Ware and Mehta (2008), which will be described in detail 
in the statistical analysis plan.  The sample size will be increased if either CMR or OS 
interim results are in the pre-specified promising zone.  If the sample size is increased 
due to only OS results being in the promising zone, then the primary CMR analysis will 
occur as scheduled once 296 subjects have been assessed for CMR. 
The interim futility boundaries will use the Lan-DeMets alpha-spending approach to 
non-binding O’Brien-Fleming boundaries.

10.4.2 
Data Monitoring Committee 
An external independent DMC will oversee the interim analyses.  In addition, the DMC 
will assess safety approximately every 6 months provided enrollment is adequate.  The 
timing of safety reviews may be adjusted in order to coincide with scheduled DMC 
interim analyses for futility and efficacy.  On the basis of their reviews, the DMC will 
make recommendations to Amgen regarding the continuation of the study and sample 
size re-estimation of the study.  The DMC will consist of 3 or more members including 
2 or more clinicians with relevant specialties and 1 or more statisticians.  The DMC will 
be supported by an external independent statistician who is responsible for preparing 
reports that describe the ongoing clinical study data.  Details regarding the 
responsibilities of the DMC and the independent statistician will be described in the DMC 
Charter.

Primary Analysis 
Phase 2: The primary analysis will report the CMR rate among blinatumomab treated 
subjects. 
Phase 3: The primary analysis will test whether CMR/OS is superior in the group 
randomized to blinatumomab compared to the group randomized to IC.  The primary 
analysis will be triggered by the date when 296 subjects have had the opportunity to

complete at least 1 tumor assessment.  Barring a sample-size increase, the estimated 
time of this analysis is 21 months after the first subject is randomized. 
10.4.4 
Final Analysis 
The final analysis will test whether OS is superior in the group randomized to 
blinatumomab compared to the group randomized to IC.  The final analysis will be 
triggered by the date when the 236th death in phase 3 subjects is reported in the clinical 
trial database, or the study duration reaches 12 months from the last subject 
randomized.  The estimated time is 26 months to reach the OS event goal.  Barring a 
sample-size increase, since the enrollment period is expected to last 21 months, the 
estimated maximum follow up time is 33 months. 
In case that the phase 3 portion of the study is not initiated, the final analysis will 
occur when all subjects in phase 2 complete long term follow-up defined in 
Section 7.2.7. 
10.5 
Planned Methods of Analysis  
10.5.1 
General Considerations 
Continuous variables will be summarized by the non-missing sample size (n), mean, 
standard deviation, median, first and third quartiles, minimum, and maximum.  
Categorical variables will be summarized by the n and percentage in each category.  
Time to event endpoints will be summarized with hazard ratios, Kaplan-Meier (KM) 
curves, KM proportions at select time points, KM quartiles (when estimable), the number 
of subjects with events, the number of subjects censored, and the pattern of censoring.  
Point estimates for efficacy endpoints will be accompanied by 2-sided 95% confidence 
intervals including estimates of KM quartiles (Brookmeyer and Crowley, 1982), KM 
proportions (Kalbfleisch and Prentice, 1980), and binomial proportions 
(Clopper CJ and Pearson, 1934). 
The phase 3 study will have an overall alpha of 0.025 with 1-sided testing.  To preserve 
the overall significance level, statistical testing of the primary and key secondary 
endpoint will follow a hierarchical structure.  First, CMR rate will be tested.  If the 
blinatumomab arm demonstrates superiority over the IC arm for CMR, then OS will be 
tested.

Primary Efficacy Endpoint 
Phase 2: 
The percentage of subjects with a CMR during the first 12 weeks after initiation of 
blinatumomab will be summarized with an exact binomial 95% confidence interval.  
Summary of CMR during the treatment will also be provided.  
Phase 3: 
A 1-sided Cochran-Mantel-Haensel test, which will adjust for the stratification factors at 
randomization, will be used to determine if the blinatumomab arm has a significantly 
higher CMR rate compared to the IC arm.  In addition, the percentage of subjects in 
each treatment arm with a CMR will be summarized with an exact binomial 
95% confidence interval.  Subjects missing post-baseline disease assessments will be 
considered not to have achieved CMR. 
10.5.3 
Secondary Efficacy Endpoint(s) 
Phase 2: 
Other secondary efficacy endpoints include OR after initiation of blinatumomab and 
during the treatment, PFS, duration of CMR, DOR, successful mobilization rate, 
alloHSCT rate, autoHSCT rate and 100-day NRM after autoHSCT.  
OR during the first 12 weeks after initiation of blinatumomab during the treatment will 
be summarized with an exact binomial 95% confidence interval.  
PFS will be summarized with the KM summaries.  
Duration of CMR and duration of response will be summarized with the KM summaries 
in Responders Analysis Set. 
Successful mobilization rate, autoHSCT rate and alloHSCT rate will be summarized with 
an exact binomial 95% confidence interval. AutoHSCT rate will be analyzed using 
autoHSCT Analysis Set.  
The 100-day NRM after autoHSCT rate will be summarized with the cumulative 
incidence function with relapse or deaths due to relapse treated as competing risks.  
For this endpoint, time to non-relapse deaths will be measured starting from the date of 
autologous HSCT. 
Phase 3: 
OS is the key secondary efficacy endpoint for Phase 3.  A 1-sided stratified log-rank test, 
stratified by the randomization factors, will be used to determine if OS is superior in the

blinatumomab arm compared to IC arm when the 236th death in phase 3 subjects is 
reported.  In addition, a hazard ratio with a 2-sided 95% confidence interval will be 
estimated from a stratified Cox regression model.  The KM summaries will be performed 
by treatment group.  
Other secondary efficacy endpoints include OR, PFS, duration of CMR and ORR, 
successful mobilization rate, HSCT rate, 100-day NRM after HSCT rate.  Overall 
response rate will be summarized by treatment group with an exact binomial 
95% confidence interval.  For descriptive purposes, a 1-sided Cochran-Mantel-Haenszel 
test, which will adjust for the stratification factors at randomization, will test if the 
blinatumomab arm has a higher ORR compared to the IC arm.  PFS, duration of CMR 
and the duration of ORR will be summarized with the KM summaries by treatment group.  
For descriptive purposes, a stratified log-rank test, stratified by the randomization 
factors, will be provided.  A hazard ratio with a 2-sided 95% confidence interval will be 
estimated from a stratified Cox regression model.  
Successful mobilization rate and HSCT rate will be summarized by treatment group with 
an exact binomial 95% confidence interval. 
The 100-day NRM after autologous HSCT rate will be summarized with the cumulative 
incidence function with non-relapse deaths treated as competing risks by treatment 
group.  For this endpoint, time to non-relapse deaths will be measured starting from the 
date of autologous HSCT.

(AE) to a system organ class and a preferred term.  AEs of interest (EOI) categories will 
be based on search strategies defined by Medical Coding.  All adverse event tables will 
be summarized by treatment group.  Treatment-emergent adverse events are events 
with an onset after the administration of the first dose of protocol-specified therapy. 
The subject incidence of AEs will be summarized for all treatment-emergent AEs, 
serious AEs, AEs leading to withdrawal of protocol-specified therapy, and fatal AEs. 
Subject incidence of all treatment-emergent AEs, serious AEs, AEs leading to 
withdrawal of IP, and fatal AEs will be tabulated by system organ class and preferred 
term in descending order of frequency; similar summaries will be repeated for EOIs.

Time to onset and duration of selected EOIs (infection and neurologic events) may also 
be summarized. 
For phase 3, a summary of treatment-emergent AEs with at least a 5% higher subject 
incidence in 1 treatment arm compared to the other will be presented by preferred term.  
This summary will be repeated for serious AEs using a 10% threshold.  
A summary of treatment-emergent AEs will be tabulated by system organ class, 
preferred term, and worst grade. 
Subgroup analyses (if there is a medical or regulatory rationale) will be presented by 
system organ class and preferred term in descending order of frequency.  All races (if 
appropriate) with less than 5% of the total subjects will be pooled together for summary 
purposes. 
10.5.4.2 
Laboratory Test Results 
Shift tables between the worst post-baseline and baseline grades for selected laboratory 
parameters will be provided.  Plots or other summaries overtime will be presented for 
selected laboratory parameters including immunoglobulins, platelets, and liver 
parameters for subjects in the Safety Analysis Set.  The summary will be done by 
treatment group for phase 3. 
10.5.4.3 
Vital Signs 
The number and percentage of subjects with abnormal changes in systolic blood 
pressure, diastolic blood pressure and heart rate will be summarized for subjects in the 
Safety Analysis Set.  The summary will be done by treatment group for phase 3.

Electrocardiogram 
The ECG measurements from this clinical study were performed as per standard of care 
for routine safety monitoring, rather than for purposes of assessment of potential QTc 
effect.  Since these evaluations may not necessarily be performed under the rigorous 
conditions expected to lead to meaningful evaluation of QTc data; summaries and 
statistical analyses of ECG measurements are not planned, and these data would not be 
expected to be useful for meta-analysis with data from other trials.

will be summarized with an additional breakdown of the number of cycles completed, 
discontinued, and re-started.  In addition, the duration of therapy, the relative treatment 
duration, the cumulative dose, and the percent of intended dose will be summarized by 
cycle and overall.  The number and percent of subjects with dose modifications (eg, 
dose changes, dose interruptions) and reason for modification will be summarized.  The 
summary will be done by treatment group for phase 3.

Exposure to Concomitant Medication 
The number and proportion of subjects receiving concomitant medications from study 
day 1 through safety follow-up will be summarized by preferred term as coded by the 
World Health Organization Drug (WHODRUG) dictionary in the Safety Analysis Set.  In 
addition, the number and proportion of subjects receiving anticancer therapies (including 
HSCT conditioning regimens) during long term follow-up will be summarized by

Pharmacokinetic assessments 
Pharmacokinetic sample analysis will be performed by a central laboratory.  
Blinatumomab will be measured in all subjects who received blinatumomab at predose 
and at steady state on days 2, 9, and 16.  Serum concentrations will be measured with a 
validated assay.  Steady state serum concentrations will be summarized by dose levels 
and time points with descriptive statistics.  The following PK parameters will be 
estimated if data supports: 
• Steady state concentration 
• Systemic clearance 
• Half life

Non-IP(s) and or medical device(s) documentation 
In addition, all original source documents supporting entries in the eCRFs must be 
maintained and be readily available. 
Retention of study documents will be governed by the Clinical Trial Agreement. 
12.3 
Study Monitoring and Data Collection 
The Amgen representative(s) and regulatory authority inspectors are responsible for 
contacting and visiting the investigator for the purpose of inspecting the facilities and, 
upon request, inspecting the various records of the clinical study (eg, eCRFs and other 
pertinent data) provided that subject confidentiality is respected. 
The Clinical Monitor is responsible for verifying the eCRFs at regular intervals 
throughout the study to verify adherence to the protocol; completeness, accuracy, and 
consistency of the data; and adherence to local regulations on the conduct of clinical 
research.  The Clinical Monitor is to have access to subject medical records and other 
study-related records needed to verify the entries on the eCRFs. 
The investigator agrees to cooperate with the Clinical Monitor to ensure that any 
problems detected in the course of these monitoring visits, including delays in 
completing eCRFs, are resolved. 
In accordance with ICH GCP and the sponsor’s audit plans, this study may be selected 
for audit by representatives from Amgen’s Global Research & Development Compliance 
and Audit function (or designees).  Inspection of site facilities (eg, pharmacy, 
protocol-required therapy storage areas, laboratories) and review of study-related 
records will occur to evaluate the study conduct and compliance with the protocol, ICH 
GCP, and applicable regulatory requirements.

Data capture for this study is planned to be electronic: 
• 
All source documentation supporting entries into the eCRFs must be maintained and 
readily available. 
• 
Updates to eCRFs will be automatically documented through the software’s “audit 
trail”. 
• 
To ensure the quality of clinical data across all subjects and sites, a clinical data 
management review is performed on subject data received at Amgen.  During this 
review, subject data are checked for consistency, omissions, and any apparent 
discrepancies.In addition, the data are reviewed for adherence to the protocol and 
GCP. To resolve any questions arising from the clinical data management review 
process, data queries are created in the EDC system database for site resolution 
and subsequently closed by the EDC system or by an Amgen reviewer. 
• 
The investigator signs only the Investigator Verification Form for this EDC study or 
the investigator applies an electronic signature in the EDC system if the study is set 
up to accept an electronic signature. This signature indicates that investigator 
inspected or reviewed the data on the eCRF, the data queries, and agrees with the 
content. 
12.4 
Investigator Responsibilities for Data Collection 
The investigator is responsible for complying with the requirements for all assessments 
and data collection (including subjects not receiving protocol-required therapies) as 
stipulated in the protocol for each subject in the study.  For subjects who withdraw prior 
to completion of all protocol-required visits and are unable or unwilling to continue the 
Schedule of Assessments (Table 5 to Table 9), the investigator can search publically 
available records [where permitted]) to ascertain survival status.  This ensures that the 
data set(s) produced as an outcome of the study is/are as comprehensive as possible.  
12.5 
Language 
All written information and other material to be used by subjects and investigative staff 
must use vocabulary and language that are clearly understood.  
12.6 
Publication Policy 
To coordinate dissemination of data from this study, Amgen may facilitate the formation 
of a publication committee consisting of several investigators and appropriate Amgen 
staff, the governance and responsibilities of which are set forth in a Publication Charter.  
The committee is expected to solicit input and assistance from other investigators and to 
collaborate with authors and Amgen staff as appropriate as defined in the Publication 
Charter.  Membership on the committee (both for investigators and Amgen staff) does 
not guarantee authorship.  The criteria described below are to be met for every 
publication.

Appendix A.  Additional Safety Assessment Information 
Adverse Event Grading Scale 
The CTCAE is available at the following location:  
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm 
Drug-induced Liver Injury Reporting & Additional Assessments  
Reporting 
To facilitate appropriate monitoring for signals of DILI, cases of concurrent AST or ALT 
and TBL and/or INR elevation according to the criteria specified in Section 6.5 require 
the following: 
• 
The event is to be reported to Amgen as a serious adverse event within 24 hours of 
discovery or notification of the event (ie, before additional etiologic investigations 
have been concluded) 
• 
The appropriate eCRF (eg, Event CRF) that captures information necessary to 
facilitate the evaluation of treatment-emergent liver abnormalities is to be completed 
and sent to Amgen.  
Other events of hepatotoxicity and potential DILI are to be reported as serious adverse 
events if they meet the criteria for a serious adverse event defined in Section 9.2.2.2. 
Additional Clinical Assessments and Observation 
All subjects in whom IP(s) or protocol-required therapies is/are withheld (either 
permanently or conditionally) due to potential DILI as specified in Table 4 or who 
experience AST or ALT elevations > 3 x ULN or 2-fold increases above baseline values 
for subjects with elevated values before drug are to undergo a period of “close 
observation” until abnormalities return to normal or to the subject’s baseline levels.  
Local laboratory assessments that are to be performed during this period include:  
• 
Repeat AST, ALT, ALP, bilirubin (total and direct), and INR within 24 hours  
• 
In cases of TBL > 2x ULN or INR > 1.5, retesting of liver tests, BIL (total and direct), 
and INR is to be performed every 24 hours until laboratory abnormalities improve

Testing frequency of the above laboratory tests may decrease if the abnormalities 
stabilize or the IP(s) or protocol-required therapies has/have been discontinued AND the 
subject is asymptomatic. 
• 
Initiate investigation of alternative causes for elevated AST or ALT and/or elevated 
TBL. The following are to be considered depending on the clinical situation: 
− 
Complete blood count (CBC) with differential to assess for eosinophilia 
− 
Serum total IgG, Anti-nuclear antibody (ANA), Anti Smooth Muscle Antibody, and 
Liver Kidney Microsomal antibody 1 (LKM1) to assess for autoimmune hepatitis 
− 
Serum acetaminophen (paracetamol) levels 
− 
A more detailed history of:  
• 
Prior and/or concurrent diseases or illness 
• 
Exposure to environmental and/or industrial chemical agents  
• 
Symptoms (if applicable) including right upper quadrant pain, 
hypersensitivity-type reactions, fatigue, nausea, vomiting and fever 
• 
Prior and/or concurrent use of alcohol, recreational drugs and special diets 
• 
Concomitant use of medications (including non-prescription medicines and 
herbal and dietary supplements), plants, and mushrooms 
− 
Viral serologies 
− 
CPK, haptoglobin, LDH, and peripheral blood smear 
− 
Appropriate liver imaging if clinically indicated 
• 
Appropriate blood sampling for PK analysis if this has not already been collected  
• 
Hepatology consult (liver biopsy may be considered in consultation with an 
hepatologist) 
• 
Follow the subject and the laboratory tests (ALT, AST, TBL, INR) until all laboratory 
abnormalities return to baseline or normal or considered stable by the investigator. 
The “close observation period” is to continue for a minimum of 4 weeks after 
discontinuation of all IP(s) and protocol-required therapies. 
The potential DILI event and additional information such as medical history, concomitant 
medications and laboratory results must be captured in the corresponding eCRFs.

Section:  2.1.1 Primary Refractory or Relapsed Disease 
Replace: 
Patients with DLBCL who do not respond to frontline therapy, or who experience 
relapse after a remission, are generally considered incurable unless able to receive 
either high dose chemotherapy (HDT) with autologous HSCT or allogeneic HSCT 
(Robinson et al, 2016).  HSCT is preceded by a course of salvage chemotherapy.  
“Chemoresponsivess”, indicating a partial response (PR) or complete response (CR) to 
salvage chemotherapy, has been as used as 1 criterion to define HSCT eligibility, since 
early trials demonstrated the extremely poor outcomes of patients without an objective 
response to salvage chemotherapy (Philip et al, 1987).  It is not known if responsiveness 
to newer classes of therapies, such as those that are immune-based, may also be 
sufficient to permit the successful use of HDT.

Section:  2.1.2 First Salvage Chemotherapy, paragraph 1 
Add:   
The most commonly used regimens in the S1 treatment of transplant-eligible patients 
contain rituximab and a platinum-based agent such as cisplatin (eg, R-DHAP, R-GDP, 
R-ESHAP) or carboplatin (eg R-ICE) (Crump et al, 2014; Martin et al, 2008; 
Witzig et al, 2008; Kewalramani et al, 2004).  Each regimen is administered over 
4-5 days every 2-4 weeks.  Two to three cycles of therapy are given before response 
assessment.  Those with PR or CR typically undergo HSC mobilization and an additional 
1-2 cycles may be given before HDT/HSCT.  Non-responders, if offered additional 
chemotherapy, typically receive an alternative regimen.

10.2.1 Phase 2 
The sample size for the phase 2 part of the study is determined by a 1-sample test of the 
rate of CMR after 1 cycle of blinatumomab.  With the 1-sided type I error rate (α) set at 
0.025, a null hypothesis response probability (π0) of 15%, and an alternative response 
probability (π1) of 40%, a sample size of 36 subjects will provide 90% power to reject the 
null hypothesis that the response probability is no more than 15%.  Being able to make 
this determination will represent evidence of clinical activity and warrant advancement 
into the phase 3 part of the study.

Section:  10.4.4 Final Analysis, paragraph 2 
Add: 
The final analysis will test whether OS is superior in the group randomized to 
blinatumomab compared to the group randomized to IC.  The final analysis will be 
triggered by the date when the 236th death in phase 3 subjects is reported in the clinical 
trial database, or the study duration reaches 12 months from the last subject 
randomized.  The estimated time is 26 months to reach the OS event goal.  Barring a 
sample-size increase, since the enrollment period is expected to last 21 months, the 
estimated maximum follow up time is 33 months. 
In case that the phase 3 portion of the study is not initiated, the final analysis will 
occur when all subjects in phase 2 complete long term follow-up defined in 
Section 7.2.7.
