1)
The planned duration of a treatment cycle is 14 days; and up to 17 days from Cycle 2, in case the D8 is delayed by maximum 3 days. In case of toxicity, the start of the 
next cycle maybe delayed by maximum of 14 days to allow for recovery.
2)
EOT is the End of treatment visit and should be done at the earliest 30 days and no later than 42 days after the last dose for those patients completing all 6 cycles 
according to protocol. If a patient is prematurely withdrawn from treatment (i.e. earlier than the end of the 6th cycle), an EOT visit should be performed within 14 days 
after last dose (last administration of Gemcitabine, Oxaliplatin or BI836826, whichever is the latest).
3)
FU AEs visit: The information collected at this visit should include all new AEs that occurred after the last dose and a follow-up of adverse events ongoing at the time of 
the last dose. If a patient has been prematurely withdrawn from treatment, the FU for AEs visit must be performed on site 30-42 days after the last dose. If a patient 
completes the 6 cycles according to the protocol the FU for AEs visit can be scheduled at the same time point as EOT visit. 
4)
Follow-up visits (FU) see section 6.2.5: After the FU for AEs, the patient will be followed for disease assessment/vital status (remission/progression/death/new anti-
lymphoma treatment) and drug related SAEs and AESIs. These FU visits should take place every 3 months for the first year after FU for AEs visit, and then every 6 
months until death, patient is lost to follow-up, patient withdraws consent for further follow up or the end of trial is reached. FU may be performed by telephone interview 
in case the patient is unable to visit the investigator.
5)
In cycle 1, during the first infusion of BI 836826 the patients are required to be hospitalized for at least 24hrs under close surveillance with access to intensive care.
6)
The naming of the visit follows the cycle number and day of treatment, i.e. Day 1 cycle 1 will read C1D1 and Day 8 cycle 2 will read C2D8.
7)
Single electrocardiogram (ECG) to be performed before any blood sampling at screening, day 8 in cycle 4 (C4D8) and EOT. Please note that on C4D8, ECG has to be 
performed before the infusion and immediately after the end of the infusion of BI 836826.
8)
Confirm availability of archival tissue. If the required amount of tumor tissue is not available, fresh biopsy is mandatory. Sample must be shipped to central laboratory.
See Section 5.5.1.1
    
10) Screening for TLS has to be performed within 24hrs of first dose of BI 836826 in patients at risk of TLS (high tumor burden) see section 5.3.3.2.
11) Mandatory tests at screening: see 5.3.3.3 virology: HIV antibody, CMV- Ig G, CMV-IgM, HbsAg, anti-HBc, anti-HCV. If patient is positive for anti-HCV during 
screening, the HCV-RNA test can be performed to exclude false positive results. If HCV-RNA test is negative, patient may be enrolled
 
13) Flow cytometry: quantitative assessment of: B cells, T cells, NK cells required at C1D1, C4D1 and EOT visit. Blood samples to be sent to a Central laboratory.
14) Pharmacokinetics for dosing times and cycles see Appendix 10.1, Table 10.1:1
 
16) Patients will be registered via interactive response technology (IRT) at screening and at each time-point trial medication is dispensed as well as at EOT. 
17) PET/CT Scan of neck, thorax, abdomen, and pelvis to be performed at each time.  
a)
Baseline PET/CT scan: up to 28 days prior to C1D1
b)
Interim PET/CT scan: after C3, i.e. prior to C4D1
c)
Final PET/CT scan: 3-6 weeks after the last dose if 6 cycles have been completed.
18) Disease assessment/vital status is collected at baseline, after the interim PET/ CT scan, i.e. after the end of cycle 3 and before C4D1 at EOT and during follow up visits.

1)
The planned duration of a treatment cycle is 14 days; and up to 17 days from Cycle 2, in case the D8 is delayed by maximum 3 days. In case of toxicity, the start of the 
next cycle maybe delayed by maximum of 14 days.
2)
EOT is the End of treatment visit and should be done at the earliest 30 days and no later than 42 days after the last dose for those patients completing all 6 cycles 
according to protocol. If a patient is prematurely withdrawn from treatment (i.e. earlier than the end of the 6th cycle), an EOT visit should be performed within 14 days 
after last dose (last administration of Gemcitabine, Oxaliplatin or BI836826, whichever is the latest)
3)
FU AEs: The information collected at this visit should include all new AEs that occurred after the last dose and a follow-up of adverse events ongoing at the time of the 
last dose. If a patient has been prematurely withdrawn from treatment, the FU for AEs visit must be performed on site 30-42 days after the last dose. If a patient 
completes the 6 cycles according to the protocol the FU for AEs visit can be scheduled at the same time point as EOT visit. 
4)
Follow-up visits (FU) see section 6.2.5: After the FU for AEs, the patient will be followed for disease assessment/ vital status (remission/progression/death/new anti-
lymphoma treatment) and drug related SAEs and AESIs. These FU visits should take place every 3 months for the first year after FU for AEs visit, and then every 6 
months until death, patient is lost to follow-up, patient withdraws consent for further follow up or the end of trial is reached. FU may be performed by telephone interview 
in case the patient is unable to visit the investigator
5)
In cycle 1, during the first infusion of BI 836826 the patients are required to be hospitalized for at least 24hrs under close surveillance with access to intensive care.
6)
The naming of the visit follows the cycle number and day of treatment, i.e. Day 1 cycle 1 will read C1D1 and Day 8 cycle 2 will read C2D8
7)
Single electrocardiogram (ECG) are to be performed before any blood sampling at screening, day 8 in cycle 4 (C4D8) and EOT. Please note that on C4D8, ECG has to be 
performed before the infusion and immediately after the end of the infusion of BI 836826.
    
10) Screening for TLS has to be performed within 24hrs of first dose of BI 836826 in patients at risk of TLS (high tumor burden) see section 5.3.3.2.
11) Mandatory tests at screening: see 5.3.3.3 virology: HIV antibody, CMV- Ig G, CMV-IgM, HbsAg, anti-HBc, anti-HCV. If patient is positive for anti-HCV during 
screening, the HCV-RNA test can be performed to exclude false positive results. If HCV-RNA test is negative, patient may be enrolled.
12) Quantitative Cytomegalovirus (CMV), Deoxyribonucleic acid (DNA), polymerase chain reaction (PCR) to be performed at screening, C1D1,C2D1, C4D1, C6D1 and 
EOT. 
13) Flow cytometry: quantitative assessment of: B cells, T cells, NK cells required at C1D1 C4D1 and EOT visit. Blood samples to be sent to a Central laboratory.
14) Pharmacokinetics for dosing times, days and cycles see Appendix 10.1, Table 10.1.2.
 
16) Patients will be registered via interactive response technology (IRT) at screening and at each time-point trial medication is dispensed as well as at EOT.
17) PET/CT Scan of neck, thorax, abdomen, and pelvis to be performed at each time.
a)
Baseline PET/CT scan : up to 28 days prior to C1D1
b)
Interim  PET/CT scan : after C3, i.e. prior to C4D1
c)
Final PET/CT scan: 3-6 weeks after the last dose if 6 cycles have been completed.
18) Disease assessment/vital status is collected at baseline, after the interim PET/ CT scan, i.e. after the end of cycle 3 and before C4D1, at EOT and during follow up visits.

1. INTRODUCTION
1.1.
MEDICAL BACKGROUND
The Non-Hodgkin’s Lymphoma (NHL) encompass a number of subtypes with variable 
clinical course and outcome. Approximately 90% of NHL in western countries are of B cell 
origin NHL (R10-4834) and belong to mature B cell malignancies according to the World 
Health Organization (WHO) classification (R10-6296).The incidence of NHL of B cell origin 
is 15-20 per 100.000 (seer.cancer.gov). About 72,240 new cases of NHL were estimated for 
2017 and about 20,140 people will die (www.cancer.org) in the United States (US).
Historically, based on the clinical presentation, NHLs have been classified as indolent (low 
grade) lymphomas, or as (high grade) aggressive lymphomas. Most of the indolent types are 
nodular (or follicular) in morphology, and often with insidious presentation with slow 
growing lymphadenopathy, hepatomegaly, splenomegaly, and/or cytopenias. Early stages of 
indolent NHLs (stage I and stage II) can be effectively treated because the lymphomas are 
usually responsive to immunotherapy, radiation therapy, and chemotherapy. Patients with 
advanced stages cannot be cured (R15-0609), but have a relatively long median overall 
survival (up to 20 years) with a continuous rate of relapse over time, which can often be 
successfully re-treated as long as the disease histology remains low grade. The natural history 
and the clinical course of patients with B-cell indolent lymphomas are also characterized by 
the risk of histologic transformation (HT) to an aggressive lymphoma. This is a well-known 
phenomenon that has been extensively studied in terms of the incidence, risk factors, and
outcome in patients with follicular lymphoma (FL), which transforms to a Diffuse Large B 
cell Lymphoma (DLBCL); and, less commonly, to Burkitt lymphoma, or other types of 
aggressive lymphomas. HT has also been described in other subtypes of B-cell indolent 
lymphomas. Patients who present with, or convert to aggressive forms of NHL may have 
sustained complete remissions with combination chemotherapy regimens or aggressive 
consolidation with marrow or stem cell support.
Aggressive lymphomas commonly develop acutely or sub-acutely with a rapidly growing 
mass, systemic B symptoms (i.e., fever, night sweats, weight loss), and/or elevated levels of 
serum lactate dehydrogenase (LDH) and uric acid. Examples of lymphomas with this 
aggressive presentation include DLBCL, Burkitt lymphoma, adult T cell leukemia-
lymphoma, or precursor B and T lymphoblastic leukemia/lymphoma. Untreated aggressive 
lymphomas have very short natural history, but with progress in recent years a significant 
number of patients can be cured with intensive combination regimens. DLBCL is the most 
common lymphoma and accounts for approximately 25 percent of all NHLs in the developed 
world (R15-0608, R10-6296). Advanced stage DLBCL is treated primarily with systemic 
chemotherapy (CHOP regimen: Cyclophosphamide, Hydroxydaunorubicin, Oncovin , and
Prednisolone) with the addition of recombinant anti-CD20 antibody, rituximab. The addition 
of rituximab to CHOP-based therapy results in an approximately 10 to 15 percent overall 
increase in survival beginning at one year from initiation of therapy in patients of all ages 
with almost no increase in toxicity (R15-0607, R03-0720). The three year event free and 
overall survival for treated patients is 79 and 93% respectively (P12-05173). Unfortunately, a 
significant number of patients with DLBCL will not be cured with this approach, and will 
require subsequent treatments upon relapse. Relapsed or refractory DLBCL is treated with 
intense chemotherapy regiments with or without rituximab with plans to proceed to high-dose

chemotherapy and stem cell transplantation (SCT) in patients with chemotherapy-sensitive 
disease. The treatment of patients who (due to age and comorbidities) are not considered 
good candidates for SCT, who fail to respond to second-line chemotherapy regimens, or who 
relapse after SCT is generally palliative. In addition, patients with primary refractory disease 
rarely achieve a complete remission when treated with a second chemotherapy regimen. 
Recurrent or resistant DLBCL in patients ineligible for transplantation are particularly 
difficult to treat and have markedly reduced survival (P15-01473, P15-01472).
Therefore, the need to develop more efficacious treatments for relapsed/refractory DLBCL 
patients who are not eligible for SCT is apparent. Since monoclonal anti CD20 antibodies 
have demonstrated utility in lymphoma treatment as part of chemoimmunotherapy approach, 
it is reasonable to assume that further combinations with other monoclonal antibodies
targeting antigens present on tumor cells might also prove useful. While initial reports on the 
use of single agent rituximab for relapsed DLBCL demonstrated response rates of 
approximately 30 percent, the rate of response among patients who received rituximab as part 
of their initial treatment regimen is expected to be significantly lower. Therefore, rituximab 
may be of limited utility in these patients (P15-01471). Given that rituximab has become an 
inherent part of the standard first lane treatment in DLBCL, it is reasonable to expect that 
virtually all relapsed/refractory patients will have been pre-exposed to anti CD 20 antibody at 
some time in the past.  Using a different then CD20 target seems particularly attractive as it 
may allow overcoming resistance to CD20 antibody in those patients. 
CD37, a member of the tetraspanin superfamily, is a glycosylated cell surface protein which 
is predominantly expressed on normal B cells, with highest expression levels on mature 
peripheral blood B cells. The CD37 antigen is also expressed on the majority of malignant 
cells in patients with NHL and chronic lymphocytic leukaemia (CLL) (R08-2979, R08-2943, 
R08-2981, R08-2945, R08-2942, R14-3568, R14-3569). The physiological function of CD37 
in humans remains unknown (R08-2979, R08-2946). Mice deficient for CD37 display no 
changes in development and cellular composition of lymphoid organs but have reduced levels 
of IgG1 and attenuated T-cell mediated immune reactions (R09-5412). Studies with CD37-/-
T cells suggest a role for CD37 in T cell proliferation and regulation of immunoglobin A
(IgA) response (R09-4740, R09-5414).

DRUGS PROFILE
1.2.1.
BI 836826
BI 836826 is a mouse-chimeric antibody of the IgG1 isotype, directed against human CD37.
BI 836826 has been investigated pre-clinically and in Phase 1 dose escalation trials in chronic 
lymphocytic leukemia and NHL. 
In vitro assays demonstrated that BI 836826 specifically recognizes human CD37 and binds 
with high affinity to this antigen. BI 836826 is a potent inducer of apoptosis and antibody-
dependent cell cytotoxicity (ADCC) in vitro, but lacks complement-dependent cytotoxicity
(CDC) activity. 
In vivo testing in nude mouse lymphoma xenograft models (Ramos DOHH2 cell lines) 
showed a statistically significant growth retardation of treated tumors with single agent BI 
836826 and in combination with chemotherapy (R11-4834, n00232742, n00232752). The 
combination of BI 836826 with chemotherapeutics (bendamustine, chlorambucil,

fludarabine) or with the CD20 antibody rituximab in vitro results in additive or synergistic 
apoptosis induction on lymphoma cell lines and primary CLL cells (R12-4648).
The majority of effects observed in the general toxicity studies with BI 836826 in HuCD37 
mice and with the surrogate BI 836847 (an anti-macaque CD37 surrogate antibody) in 
cynomolgus monkeys were directly related or secondary to the pharmacological activity of BI 
836826 and BI 836847. The main target organs following repeat intravenous exposure to BI 
836826 in HuCD37 mice and to the surrogate BI 836847 (an antimacque CD37 surrogate
antibody) in cynomolgus monkeys were the blood and lymphoid system. BI 836826 induced 
B- but also T-cell reduction in HuCD37 mice in peripheral blood and lymphoid organs at all 
dose levels with the histopathological correlate of lymphoid depletion in B-cell areas in 
spleen and lymph nodes. In contrast, the surrogate BI 836847 induced reduction of 
lymphocytes, predominantly B cells and natural killer cells (NK cells) at low to moderate 
doses. T cells, granulocytes and platelets (PLT) were reduced at higher doses. Severe and 
sustained immunosuppression in monkeys treated with high doses led to several cases of 
septicaemia. Further details regarding the full safety profile from toxicological studies in 
animals can be found in the Investigator’s Brochure (IB). 
1.2.2.
Human experience with BI 836826
Preliminary data from two ongoing Phase 1 monotherapy trials are available, one in relapsed 
CLL (study 1270.1, 37 patients) and the other in relapsed NHL (study 1270.2, 45 patients).
Two different treatment schedules were used: 
∀
in patients with r/r CLL (study 1270.1), BI 836826 was administered every 2 weeks 
until disease progression; 
∀
in relapsed NHL (study 1270.2), BI 836826 was administered weekly in 3 courses of 
treatment with a total of up to 12 injections.

In summary, based on the experience with BI836826 monotherapy in CLL at doses up to 
800mg and in NHL at doses up to 200mg, two (2) MTDs have been established: 400mg in 
monotherapy for CLL and 100mg for NHL. The MTD in the NHL study (1270.2) was 
determined based on DLTs seen at 150mg (asymptomatic laboratory abnormalities that 
resolved within 48 hours). Therefore, in the ongoing study (1270.11) in combination with 
GemOx, and using a different treatment schedule, it is legit to consider that a different dose 
of BI 836826 might be possible and might be higher than the 100mg defined as MTD in 
monotherapy in NHL.
For a more detailed description of the drug profile refer to the current IB which is included in 
the Investigator Site File (ISF).
1.2.3.
Gemcitabine
Gemcitabine (dFdC), is a pyrimidine antimetabolite, which exerts its cytotoxic effect by 
inhibition of DNA synthesis. Gemcitabine shows significant cytotoxic effects against a 
variety of cultured murine and human tumor cells. Its action is phase-specific such that 
gemcitabine primarily kills cells that are undergoing DNA synthesis (S phase) and, under 
certain circumstances, blocks the progression of cells at the junction of the G1/S phase 
boundary. In vitro, the cytotoxic effect of gemcitabine is dependent on both concentration 
and time.
Gemcitabine is mostly used for treatment of variety of solid tumors as monotherapy, or in 
combinations with other chemotherapeutic agents. Recent studies in lymphoma indicate that 
gemcitabine in combination with oxaliplatin and rituximab (R-Gem-Ox regimen) can be 
considered as a salvage regimen for elderly patients with DLBCL because of its high clinical 
activity and relatively safe toxicity profile, (P13-00889, R14-2111)
The most common (in >10% of treated patients) adverse effects of gemcitabine include. 
∀
Leukopenia, including G3-4 neutropenia 
∀
Nausea and/or vomiting
∀
Elevation in liver enzymes (aspartate amino transferase (AST), alanine amino transferase
(ALT) and alkaline phosphatase (AP))
∀

For additional detailed information please refer to the summary of product 
characteristic (SmPC) located in the ISF. Oxaliplatin 
Oxaliplatin is an antineoplastic drug belonging to a new class of platinum-based compounds
which interact with DNA to form both inter and intra-strand cross-links, resulting in the 
disruption of DNA synthesis and leading to cytotoxic and antitumor effects. Oxaliplatin 
exhibits a wide spectrum of both in vitro cytotoxicity and in vivo antitumor activity in a 
variety of tumor model systems including human colorectal cancer models. A synergistic 
cytotoxic action has been observed in combination with 5-fluorouracil both in vitro and in 
vivo. Oxaliplatin is indicated for treatment in combination with 5-Fluorouracil and folinic 
acid for treatment in patients with colorectal cancers. 
Recent studies in lymphoma indicate that oxaliplatin in combination with gemcitabine and 
rituximab (R-Gem-Ox regimen) can be considered as a salvage regimen for elderly patients 
with DLBCL because of its high clinical activity and relatively safe toxicity profile (P13-
00889, R14-2111),
Most common adverse effects reported for oxaliplatin are 
∀
Neurological symptoms and peripheral neuropathy 
∀
Thrombocytopenia, anemia, and neutropenia
∀
Infections
∀
Nausea, vomiting and diarrhea
∀
Infusion reactions with flushing, headache, dyspnea and/or hypotension. 
∀
Grade 3/4 hypersensitivity, including anaphylactic/anaphylactoid reactions, to oxaliplatin has 
been observed. These allergic reactions which can be fatal, can occur within minutes of 
administration and at any cycle, and were similar in nature and severity to those reported with 
other platinum-containing compounds, such as rash, urticaria, erythema, pruritus, and, rarely, 
bronchospasm and hypotension. Re-challenge is contraindicated in those patients.
For additional information please refer to the SmPC located in the ISF.
1.2.5.
Rituximab (only in Part 2)
Rituximab is a genetically engineered chimeric mouse/human monoclonal antibody 
representing a glycosylated immunoglobulin with human IgG1 constant regions and murine 
light-chain and heavy chain variable region sequences. The antibody is produced by 
mammalian (Chinese hamster ovary) cell suspension culture and purified by affinity 
chromatography and ion exchange, including specific viral inactivation and removal 
procedures.

Rituximab targets CD20, a specific B-cell surface antigen. The binding of rituximab to the 
CD20 located on B lymphocytes results in cell destruction via three potential mechanisms: 
antibody-dependent cell cytotoxicity (ADCC), CDC and modest, if any, induction of 
apoptosis. This drug is administered intravenously, and is indicated for treatment of patients 
with various NHLs, CLL, and autoimmune diseases. Rituximab is also frequently used in 
clinical practice for treatment of patients with relapsed/refractory NHL either as part of multi-
drug regimens, or less frequently, as monotherapy.
Rituximab is contraindicated in patients who are hypersensitive to the active substance or to 
murine proteins, or to any of the other excipients, in patients with active, severe infections, 
and in patients with severe immunosuppression.
The most common adverse events (>10% of treated patients) reported for treatment with 
rituximab are:
∀
Infections: bacterial and viral
∀
Hematologic toxicities: neutropenia, leucopenia,  febrile neutropenia,  and   
thrombocytopenia
∀
IRR, including angioedema
∀
nausea
∀
skin reactions: pruritus, rash, alopecia
∀
fever, chills, asthenia, headache
∀
decreased IgG levels
Special warnings and precautions for use of rituximab include: 
∀
IRR
∀
skin reactions including toxic epidermal necrolysis (Lyell’s syndrome) and Stevens-
Johnson syndrome, some with fatal outcome, 
∀
serious infections, including hepatitis B reactivation 
∀
rare, but fatal progressive multifocal leukoencephalopathy. 
Tumor lysis syndrome and IRR usually occur in patients with high numbers of circulating 
tumor cells and in patients with high tumor burden, particularly if rituximab is administered 
in combination with chemotherapy. Angina pectoris, cardiac arrhythmias such as atrial flutter 
and fibrillation, heart failure and/or myocardial infarction are also reported. Therefore 
patients with a history of cardiac disease and/or cardio toxic chemotherapy should be 
monitored closely.

2. RATIONALE, OBJECTIVES, AND BENEFIT - RISK ASSESSMENT
2.1.
RATIONALE FOR PERFORMING THE TRIAL
A substantial number of patients relapse after first line therapy for DLBCL and many of them 
will not be good candidates for intensive treatment with curative intent due to age or co-
morbidities (R10-4775, P12-05173). These patients will rather receive palliative treatment 
with the aim to control the disease, while maintaining reasonable quality of life. There are 
different options of combination chemotherapy in relapsed/refractory DLBCL setting, but
none has proven superior, and there is no approved standard treatment in this group of 
patients. Treatment regimens used in elderly patients with relapsed/refractory DLBCL are 
reported to achieve response rates in the range of 50-70%, however many of those are partial 
responses and rather of short duration (P14-08836, P10-10101, R14-2310). The progression 
free survival and overall survival are generally short (P14-08836, P10-10101). One of the 
regimens used in patients ineligible for intensive therapy is a combination of rituximab, 
gemcitabine and oxaliplatin (R-GemOx) (R13-0204, P13-00889, R13-0203 and R14-2111). 
So far limited numbers of patients have been included in trials with this triple combination, 
but the results from Phase 2 multicenter trial with 48 patients are encouraging. The trial 
demonstrated an overall response rate (ORR (CR+PR)) of 61% after 4 cycles of treatment
(R13-0204, P13-00889, R13-0203 and R14-2111). The 5 years progression free survival 
(PFS) and overall survival (OS) were 12.8 and 13.9% respectively. In addition, the R-GemOx 
regimen is relatively well tolerated with reversible hematologic toxicity and infections being 
the most frequent adverse events. Interestingly, prior exposure to rituximab seems to 
negatively affect responses in these patients (23 vs 65%). Emerging data from other trials in 
similar patient populations indicate that upon re-treatment with rituximab patients who 
received rituximab in their first line therapy have lower response rates and shorter event free 
survival compared to those who first received rituximab at relapse (R11-2236, P10-10101, 
R14-2111). Considering that rituximab became standard of care in western countries and 
almost all DLBCL patients receive rituximab as part of the initial therapy, it is concerning 
that combinations containing rituximab may not be the best treatment choice for those 
patients at relapse. One approach to avoid cross-resistance could be through targeting a 
different than CD20 antigen on the surface of tumor cells.
The majority of malignant cells in patients with NHL of B cell origin express the CD37 
antigen, so targeting CD37 in malignancies may offer a valid treatment option (R08-2979, 
R08-2943, R08-2981, R08-2945, R08-2942, R14-3568, R14-3569). BI 836826 targets an 
epitope on the tumor cells which has not previously been therapeutically targeted, thus
offering an advantage of avoiding cross-resistance with prior monoclonal antibody based 
therapies, The addition of BI 836826 to chemotherapy backbone in patients progressing after 
rituximab (or another anti-CD20 targeting mAb) offers a potential to overcome resistance to 
anti-CD20 monoclonal antibody and may improve the response rate and prolong survival in 
patients who are not eligible for high dose therapy. 
The preliminary clinical experiences with targeting CD37 with MB-1, a radio-immuno-
conjugate and TRU-016, a small modular immuno-pharmaceutical support the assumption

that targeting CD37 in man leads to lymphocyte reduction and consecutive lymph node 
shrinkage with an acceptable side effect profile (R10-2734, R10-2735, R10-6640).
The purpose of Part 1 (dose-escalation) of the trial is to establish the recommended dose of 
BI 836826 in combination with GemOx, based on safety profile. The purpose of Part 2 
(randomized part) of the trial is to compare the overall response rate (ORR) of BI 836826-
GemOx vs R-GemOx. An increase in ORR, especially in complete remission (CR) rate is 
considered a pre-requisite for improvement in PFS. Using the same chemotherapy backbone
in both arms the trial will assess whether the preclinical superiority of BI 836826 to rituximab 
also translates into a clinical setting and results in improvement in efficacy.

Primary objective: 
To establish the maximum tolerated dose (MTD) of BI 836826 in combination with GemOx.
Secondary objectives:
To evaluate pharmacokinetics of BI 836826 when given in combination with GemOx and to 
investigate preliminary efficacy in terms of the overall response rate based on investigator’s 
assessment.
Part 2 (Phase II randomized)
Primary objective: 
To investigate the efficacy by means of the overall response rate (PR+ CR) based on central 
review assessment in patients with relapsed DLBCL treated with BI 836826-GemOx 
compared to R-GemOx.
Secondary objective:
To investigate the efficacy by means of the complete remission rate based on central review 
assessment in patients with relapsed DLBCL treated with BI 836826-GemOx compared to R-
GemOx.
2.3.
BENEFIT - RISK ASSESSMENT
In preclinical studies, BI 836826 induced marked apoptosis and ADCC activity resulted in 
depletion of normal and neoplastic B cells. It is expected that these findings will translate into 
clinical setting, and will result in antitumor activity of BI 836826.
Targeting CD37 may potentially offer a benefit to patients with NHL, because BI 836826 is 
directed against an epitope on the tumor cells which has not previously been targeted by other 
drugs (for example rituximab), and therefore cross-resistance with prior therapies is not 
expected. In the preclinical settings the combination of BI 836826 with chemotherapy shows 
additive cytotoxic effect (R12-4648).
CD37 is not expressed outside of the hematopoietic and lymphatic system. The anticipated 
side effect profile of BI 836826 based on preclinical studies and initial clinical experience

comprises predominantly hematologic AEs and IRRs. The hematologic events are 
leukopenia, such as lymphocytopenia, neutropenia and thrombocytopenia. Lymphocytopenia 
and neutropenia may predispose to infections, including opportunistic infections. These 
adverse events are frequently reported in patients with hematological diseases and may be 
due to the underlying disease, previous and current treatment or combination of these. The 
neutropenia associated with BI 836826 is frequently immediate (within hours), and recovers
few days after the administration. Hematologic toxicity has also been reported with GemOx 
combination with neutrophil nadir frequently reached around day 8 after administration. In 
order to avoid long lasting neutropenia the administration schedule in this trial has been 
structured in a way that the BI 836826 infusion is scheduled on day 8, when patients may 
already be neutropenic from the GemOx treatment received on day 1. We hypothesize that 
neutropenia resulting from BI 836826 administration will fall into nadir. While it is 
conceivable that further decrease in neutrophil counts may be observed, the overall duration 
of neutropenia should be affected minimally or, not at all. Accepting shorter periods of 
neutropenia with rapid recovery is considered safer then prolonged periods with low 
neutrophil counts when infections tend to develop. Together with adjustments of
administration schedule, treatment and prophylaxis recommendations are provided in this 
protocol to ensure patients’ safety see section 4.2.1.2. and 4.2.1.3. The allowance to use 
growth factors will further allow managing neutropenia in patients on this trial. 
Severe neutropenia has rarely been observed with treatment with rituximab, therefore the 
administration schedule for R-GemOx arm will adhere to previously described dosing of 
Rituximab on day 1 and GemOx on day 2 of each cycle.
To mitigate IRRs the protocol specified precautions must be adhered to, i.e. rate controlled 
infusion schedule, premedication, monitoring of vital signs and access to intensive care 
facilities (see section 4.1.5). With the specified precautions IRRs have been manageable and 
no patient has been discontinued from BI 836826 due IRR.
There is an added risk associated with procedure of tumor tissue biopsy for patients who do 
not have archival tumor tissue available at screening and for whom a new tumor biopsy will 
be required. Those risks include: pain, swelling bleeding, and infection.
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure patients´ 
safety, see also section 5.3.3.1.
In summary, the prophylactic measures and guidance to investigators have been implemented 
in this protocol to protect patient’s safety. In Part 1 the safety review team will analyze data 
after each cohort has been completed and decide whether dose escalation to the next level is 
safe. In Part 2, the internal Data Monitoring Committee (DMC) will be appointed for this trial 
to provide additional safety oversight. Considering the advanced stage of the underlying 
malignant disease in patients on this trial the potential benefit of therapy is expected to 
outweigh the treatment-related risks.

3. DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1.
OVERALL TRIAL DESIGN AND PLAN
Population:
The trial will be conducted in patients with relapsed/refractory diffuse large B-cell lymphoma 
(including transformed follicular lymphoma) who have been previously treated with an anti-
CD20 monoclonal antibody (e.g. rituximab) in combination with an anthracycline containing 
chemotherapy and who are not eligible for, or have relapsed/progressed after autologous/ 
allogeneic stem cell transplant.
Part1 (Phase I dose escalation)
This trial consists of two parts. The Part 1 is an open-label (Phase Ib), dose-escalation 
according to a standard 3+3 design to determine the MTD of BI 836286 in combination with 
gemcitabine and oxaliplatin. The dose escalation phase will be followed by an extension 
cohort of 6 patients to be treated at the established MTD, so that a total of 12 patients will be
treated at this established MTD.
Patients will receive maximum of 6 treatment cycles. Each cycle is 14 days (it can be up to 
17 days from Cycle 2, in case the D8 is delayed by maximum 3 days). In order to continue 
trial treatment, patients must fulfill all criteria as outlined in section 6.2.2.1. In case of 
toxicity, the start of the next cycle can be delayed by up to 14 days. 
Following doses of BI 836826 will be tested in combination with GemOx: 25mg, 50mg, 
100mg, 150mg and 200mg. An additional intermediate dose might be tested.

3.1.1.
Administrative structure of the trial
This is a multicenter trial sponsored by Boehringer Ingelheim (BI) which will be conducted 
in two parts, Part 1 (Phase Ib dose escalation) with 12-14 sites mainly in Europe and 
randomized Part 2 (Phase II randomized) with 35-40 sites in Europe and the rest of the world.
The Coordinating Principal Investigator will be nominated for the trial. 
 will be helping to 
provide an oversight to the execution of the trial at all centers, will be involved in dose 
escalation decisions in Part1. A Coordinating Investigator is responsible to coordinate 
investigators at different centres participating in this multicentre trial. Tasks and 
responsibilities of all investigators will be defined in a contract. Relevant documentation on 
the participating investigators (Principal) and other important participants, including their 
curricula vitae, will be filed in the ISF and Trial Master File.
The Principal Investigators (PIs) will be hematologists experienced and specialized in the 
treatment of DLBCL. The PI at each site will be responsible for the daily conduct of the trial, 
complying with scheduled patients’visits, electronic case report form (e-CRF) completion, 
and for assisting the Clinical Research Associates (CRAs) in site monitoring.
BI has appointed a Trial Clinical Monitor (TCM), responsible for coordinating all required 
activities, in order to:
∀
manage the trial in accordance with applicable regulations and internal Standard 
Operating Procedures (SOP)s,
∀
direct the clinical trial team in the preparation, conduct, and reporting of the trial,
∀
insure appropriate training and information of Local Clinical Monitor (CML), Clinical 
Research Associates (CRAs), and investigators of participating countries.
The organisation of the trial in the participating countries will be performed by the respective 
local or regional BI-organisation (Operating Unit, OPU) in accordance with applicable 
regulations and internal SOPs, or by a Contract Research Organisation (CRO) with which the 
responsibilities and tasks will have been agreed and a written contract filed before initiation 
of the clinical trial.
Data Management and Statistical Evaluation will be done by BI according to BI SOPs.
Tasks and functions assigned in order to organize, manage, and evaluate the trial will be 
defined according to BI SOPs. A list of responsible persons and relevant local information 
can be found in the ISF.
In Part 1, a Safety Review Team consisting of the coordinating investigator, and principal 
investigators who have contributed by enrolling patients, Team member medicine (TMM), 
Team member drug safety (TMDS) and the TCM will review the clinical data regularly in 
order to assess safety (i.e. decide continuation, modification, or termination of the trial). The 
dose for the next cohort will be decided, based on the review of 3-6 patients in the same dose 
cohort, by the team.  
After completion of Part 1, enrollment to the trial will be temporary stopped to allow for 
additional assessment of benefit/risk profile. The Safety Review Team will perform careful

analysis of safety profiles at tested doses and confirm the recommendation of dose for Part 2 
of the trial. 
In Part 2, an internal DMC, independent of the trial team, will review the data in order to 
assess the safety and efficacy data from the trial. Assessment of the data will be performed at 
specified intervals to recommend whether to continue, modify or stop the trial. The tasks and 
responsibilities and scheduling of meeting for the DMC will be specified in a charter. The 
DMC will maintain written records of all its meetings.
The sponsor may outsource some responsibilities related to trial activities like: monitoring, 
trial medication supply logistics, or others.
A central laboratory service and an IRT vendor will be used in this trial. Details will be 
provided in IRT Manual and Central Laboratory Manual, available in ISF.
In part 2, a vendor will be used for central review (response evaluation) and archiving of the 
PET/CT images collected in this trial. (See further details in sections 5.2.1. and 6.2.2.5).
Details on handling of the trial supplies are given in section 4 of this protocol.
3.2.
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF
CONTROL GROUP(S)
The trial consists of two parts: Part 1, Phase Ib dose escalation and Part 2, a randomized 
Phase II. The MTD of BI 836826 established in Part 1 will be used to define the 
recommended dose for Part 2. The trial is designed as open label, since the administration 
schedule of the trial treatment is different in both arms, and blinding is not considered 
appropriate for this design. 
Part 1 
This is the first combination trial with BI 836826 and chemotherapy, therefore a careful dose 
escalation with starting dose below the MTD established for monotherapy is warranted. The 
starting dose has been selected at 25mg, which is two dose levels below the established 
monotherapy MTD of 100mg, and it is predicted to be safe. The planned 5 dose escalation 
levels should allow reaching the monotherapy MTD with the minimum required number of 
patients to gather safety data, while allowing the patients to be exposed to drug levels that 
might provide some clinical benefit.
From the definition of the MTD, and extension cohort will recruit 6 patients at that 
established MTD. The total number of patients treated at this MTD will be 12. 
Part 2
Once the MTD dose has been established in Part 1, and the recommended dose to be used is 
confirmed by the safety review team, Part 2 will be initiated. 
Patients will be randomized (1:1) to one of two treatment arms: BI 836826-GemOx, or R-
GemOx. The randomized design will allow exploring the clinical activity of BI 836826-
GemOx regimen versus R-GemOx and provide comparison data on safety for both arms. This 
randomized design will help to inform whether CD37 antibody is a valid target in this patient

population, and whether it has greater therapeutic potential than rituximab in setting of 
relapsed/refractory aggressive lymphomas in patients who are not eligible for stem cell 
transplant. 
Relapsed or refractory DLBCL is treated with systemic chemotherapy with or 
without rituximab with plans to proceed to high-dose chemotherapy and hematopoietic cell 
transplantation (HCT) in those with chemotherapy-sensitive disease. The treatment of 
patients who are not candidates for HCT, who fail to respond to second-line chemotherapy 
regimens, or who relapse after HCT is generally palliative. In the absence of HCT, 
conventional chemotherapy regimens provide only transient disease control for the majority 
of patients with relapsed or refractory DLBCL. Patients with primary refractory disease 
rarely achieve a complete remission when treated with a second chemotherapy regimen. 
Following relapse from a first complete remission, a subset of patients will achieve a second 
complete remission with chemotherapy; however, these remissions are generally not durable 
and long term disease-free survivors are rare (P15-01852). Patients that cannot tolerate the 
intensive standard chemotherapy followed by stem cell transplant are candidates for regimens 
designed for elderly patients. Examples of such regimens include: CEPP (P15-01777)
(cyclophosphamide, etoposide, prednisone, procarbazine), DA-EPOCH (P14-08837, P14-
08836) (dose-adjusted cyclophosphamide, doxorubicin, etoposide, vincristine, prednisone), 
CEOP (P15-01909) (cyclophosphamide, etoposide, vincristine, prednisone), GDP (R15-
0717) gemcitabine, dexamethasone, cisplatin), or GemOx (R14-2111, R13-0203)
(gemcitabine, oxaliplatin). All of those regimens can be given with, or without addition of 
rituximab. Alternatively, single agent therapy with anthracyclines, cytarabine, or alkylating 
agents may be used for palliation of symptoms. None of the above combination regiments is 
clearly superior over the other, and in clinical practice the choice of treatment at relapse 
frequently relies on experience of treating physician, patient’s comorbidities and possible 
toxicities. The R-GemOx combination is one of possible treatments in this setting which has 
proven safe in patients with relapsed/refractory DLBCL who are not eligible for high dose 
chemotherapy (R14-2111).
It is controversial whether rituximab should be included in the treatment of all patients with
relapsed/refractory disease. This is partially because older studies that have demonstrated a 
benefit from rituximab in the setting of relapsed disease have included few patients who 
received rituximab as part of their initial treatment. It is important to note that according to 
newer emerging data patients who have received rituximab in their first line therapy have 
lower response rates and shorter event free survival compared to those who are rituximab-
naïve at time of their relapse (P10-10101, R14-2111). All patients enrolled into this trial will 
have been previously exposed to an anti-CD20 monoclonal antibody (see, section 3.3.2.
inclusion criterion #3). The trial will provide initial data on whether such pre-exposure limits
the beneficial effect of rituximab in the salvage regimen, when compared with novel anti 
CD37 antibody targeting another antigen on tumor cells. The trial will also provide initial 
data whether CD37 antibody can be effectively used in this setting, and how the activity of BI 
836826-GemOx compares to clinical activity to R-GemOx regimen.

The patient withdraws consent for trial treatment or trial participation, without the need to 
justify the decision.
∀
The patient can no longer be treated with trial medication for other medical reasons (such 
as surgery, adverse events, other diseases, or pregnancy)
∀
Occurrence of toxicity other than lymphopenia which does not recover to Grade 1 or less 
within 14 days after the end of the 14-days cycle (meaning not recovered at D28 of cycle

general condition, which results in patient’s inability to continue trial treatment.
The patient will undergo the procedures for premature treatment discontinuation and follow 
up as outlined in the Flow Chart 1, 2, 3.
For all patients who discontinue or withdraw from the study, the reason must be recorded in 
the eCRFs. At the time of discontinuation of the study treatment, the next scheduled visit
assessments and the EoT visit assessments will be performed whenever possible, as described 
in the study procedures (see section 6.2.3), and the information will be recorded in the eCRF. 
Although treatment is discontinued, patients who do not withdraw consent for follow-up, nor 
die, nor become lost to follow-up will enter the follow-up period (see section
6.2.4 and 6.2.5). The data will be recorded in the trial database and will be reported.

(D1 to 14 of the first cycle) for reasons other than DLT, will be replaced at the same dose 
level. Patients who experienced a DLT prior to BI 836826 infusion will be replaced.
3.3.4.2. 
Discontinuation of the trial by the sponsor
BI reserves the right to discontinue the trial overall or at a particular trial site at any time for 
the following reasons:
1. Failure to meet expected enrolment goals,
2. Emergence of any efficacy/safety information invalidating the earlier positive benefit-
risk-assessment that could significantly affect the continuation of the trial,
3. Violation of GCP, the Clinical Trial Protocol (CTP), or the contract disturbing the 
appropriate conduct of the trial.
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
termination of the trial (except in case of the third reason).
3.3.4.3. 
Trial stopping rules in case of unacceptable toxicities
All AEs, including Serious Adverse Event (SAEs) and deaths will be carefully analyzed.
Unacceptable toxicity will be defined as:
∀Clinically relevant adverse events that are unexpected considering the mode of action, 
and are not manifestations of underlying disease or background events typical of the trial
population
and/or are debilitating, non-reversible, not manageable
or lead to a fatal outcome where evidence suggests that there was a reasonable 
possibility that the drug caused the adverse event
∀Higher than expected frequency of specific events (such as known consequences of the 
underlying disease or other events that commonly occur in the trial population 
independent of drug therapy) that indicates those events occur more frequently in the drug 
treatment group than would be expected in the trial population.
If one or both of the above criteria are met, the enrolment to the trial will be stopped for in-
depth analysis of the safety profile of BI 836826-GemOx. The risk-benefit profile of BI 
836826-GemOx will be re-assessed by the sponsor’s trial team, coordinating investigator and
internal DMC (in Part 2). The outcome of the analysis and the recommendations will be 
shared with all involved regulatory health authorities prior to a possible re-start of enrolment.
In case the benefit/risk assessment is no longer considered to be positive, the trial will be
stopped.

Method of assigning patients to treatment groups
The treatment group will be assigned via Interactive Response Technology (IRT). The IRT 
will be used to register the patient at screening and at all time-points trial medication is 
dispensed as well as at EOT visit. The time points for accessing the IRT system are shown in 
the Flow chart 1, 2, 3.
The complete trial medication, including BI 836826, rituximab, gemcitabine and oxaliplatin 
will be supplied by BI and managed through the IRT system. Please note that the medication 
number is the trial medication identification and is different from the patient number.
An IRT manual, describing how to access and use the IRT, will be distributed to the 
investigator, pharmacist and site personnel prior to start of the trial. 
Part 1
All patients enrolled in Part 1 will receive BI 836826 in combination with GemOx. The 
following dose levels of BI 836826 will be tested in cohorts of 3-6 patients: 25-50-100-150-
200mg (an additional intermediate dose level might be tested). The assignment to a cohort 
/dose level will be facilitated by the IRT system. 
Part 2
In Part 2, patients will be randomized in a 1:1 ratio to BI 836826-GemOx, or R-GemOx. 
Patients who have participated in Part 1 will not be eligible for Part 2. Randomization will be 
carried out centrally using IRT. The company that provides the IRT will receive the 
randomization list from Boehringer-Ingelheim Clinical Trial Support Group or a Clinical 
Research Organisation (CRO) appointed by the sponsor. The BI standard validated random 
number generating system will be used to generate the randomization schedules which will 
be verified by an independent statistician who is not involved in the trial. The access to the 
randomization code will be supervised by the Clinical Trial Support Group. People who are 
directly involved in the conduct and analysis of the trial will have no access to the 
randomization schedule.
4.1.3.
Selection of doses in the trial
BI 836826 will be given as a flat dose i.e. without any adjustment for body surface area
(BSA) or weight, in a biweekly dosing schedule (every 2 weeks). The starting dose has been 
selected at 25mg, which is two dose levels below the established monotherapy MTD of 
100mg, and it is predicted to be safe. During the dose escalation, the dose will be doubled in 
the 2 first subsequent cohorts (next dose levels: 50 and 100mg) and then escalate to 150 and

200mg cohorts. This approach was selected because it is to be safe and allows the 
achievement of an efficacious dose with minimum number of patients treated below MTD. 
The patients in a cohort will be evaluated for occurred DLTs during the 14 days observation 
period (D1 to 14 of the first cycle). Any patient withdrawing from study participation before 
D15, for reasons other than DLT, will be replaced in the cohort by a new patient, as the 
withdrawn patient is considered not evaluable. The safety profile of the cohort has to be 
assessed as tolerable by the safety review team before the next cohort can be opened for 
enrolment. The IRT system will be closed during this evaluation and it will not be possible to 
enter a patient in the trial. The investigators will be able to obtain the information about the 
next dose level from the IRT system.
The doses of gemcitabine (1000mg/m2) and oxaliplatin (100mg/m2) in a biweekly dosing 
schedule were selected based on tolerability and efficacy data from the literature (R13-0203). 
Both, gemcitabine and oxaliplatin are dosed by BSA. Patient’s weight from C1D1 should be 
used or initial calculation of BSA and the same value can be used throughout the trial as long 
as patient’s weight does not change by 10% or more. If body weight changes by >10% the 
BSA needs to be recalculated and doses of both: gemcitabine and oxaliplatin need to be 
adjusted accordingly. 
One cycle is 14 days (it can be up to 17 days from Cycle 2, in case the D8 is delayed by 
maximum 3 days), and repeated cycle starts on day 15 (or D18 in case of D8 delayed by 
maximum 3 days). In case of toxicity, the next cycle start might be delayed by a maximum of 
14 days. Patients who do not recover from toxicity within 14 days will be removed from the 
trial for toxicity reasons, and will not be allowed to re-enter the trial treatment.

4.1.4.
Drug administration of doses for each patient
Standard or routine prophylactic measures (including antiemetic’s and hydration) should be 
used prior to administration of GemOx chemotherapy to reduce the incidence of adverse 
events from these infusions. 
For premedication before antibody infusion see section 4.1.5.4. 
For handling of IRRs see section 6.2.2.3, and for tumor lysis syndrome (TLS), see section 
6.2.2.6. 
The use of transfusions and growth factors is allowed throughout the trial as clinically 
indicated.
A cycle is 14 days in length (it can be up to 17 days from Cycle 2, in case the D8 is delayed 
by maximum 3 days). The repeat cycle starts on day 15 (= day 1 of the next cycle; up to D18 
in case D8 is delayed by maximum 3 days). Up to 6 cycles can be administered, if the
treatment is well tolerated and the patient has no clinical and/or radiologic signs of 
progression, as judged by the investigator.
Before the initiation of each subsequent cycle, each patient has to be evaluated for eligibility 
to receive further treatment. If the patient does not fulfill all criteria to continue treatment as 
outlined in section 6.2.2.1, the start of the next cycle can be delayed by a maximum of 14 
days to allow recovery. Patients who do not recover during those additional 14 days will be 
withdrawn from the trial for toxicity reasons. 
The actual duration of all the infusions need to be documented in the e-CRF including actual 
start and end time, actual time points for interruptionand restart of the infusion and the actual 
infusion rates, including all steps in rate changes.
Part 1 
Gemcitabine and oxaliplatin (GemOx) will be administered as intravenous infusions on day 
1of each cycle (see section 4.1.5.3). BI 836826 will be administered as an intravenous 
infusion, on day 8 of each cycle under the supervision of the investigator or designated 
personnel.

Infusion schedules 
All patients (Part 1 and Part 2) need to fulfil criteria to continue treatment prior to starting the 
next cycle (C2-6), for details see section 6.2.2.1. The initiation of the next cycle may be 
postponed for up to 14 days to allow patients to fulfil these criteria (meaning the next cycle 
has to be started at the latest on D29, or maximum on D32 from cycle 2 and in case the D8 
was delayed by maximum 3 days).
For dose adjustment recommendations please see details below and see Table 6.2.2.1:1.
4.1.5.1.
BI 836826 infusion
BI 836826 is to be diluted into 250mL of normal saline. Premedication is mandatory (see 
section 4.1.5.4). All patients have to be hospitalized for at least 24hrs after the first infusion
of BI 836826. Please refer to table 4.1.5.1:1 for the first infusion schedule.

The total duration of the infusion may not extend 24 hours. If interruptions are necessary for 
IRR treatment, the time from the initial start of infusion until the end of infusion must be
≤ 24 hours. Any remaining solution needs to be discarded after this time.
No dose reduction or dose delay of BI 836826 is allowed in cycle 1. From Cycle 2, the D8 
can be delayed by maximum 3 days.
Only one dose of BI 836826 may be omitted from cycle 2.
4.1.5.2.
Rituximab infusion
The rituximab dose of 375mg/m2 is to be diluted into 500mL normal saline. Premedication is 
mandatory, see section 4.1.5.4. The first dose of rituximab should be given cautiously, 
starting at a slow rate and increased slowly. As recommended in the SmPC of rituximab, the 
initial rate for infusion should be a maximum of 50mg/h. After 30 minutes, the infusion rate 
can be escalated in 50mg/h increments every 30 minutes, to a maximum rate of 400mg/h.
No dose reduction or skipped dose of rituximab is allowed.
4.1.5.3.
Gemcitabine and Oxaliplatin
Gemcitabine 1000mg/m2 (diluted into 500mL of normal saline) is administered at a fixed 
dose rate of 10mg/m2/min on:
∀
day 1 if patients are participating in Part 1 or, are randomized to the BI 836826-
GemOx treatment arm in Part2 
or
∀
day 2 if patients are randomized to R-GemOx arm in Part2.
This prolonged administration schedule has been shown to achieve superior intracellular drug 
concentrations than the standard 30 min i.v. schedule (R14-4504). 
No dose reduction or skipped dose of gemcitabine is allowed.
Oxaliplatin 100 mg/m2 is to be administered after gemcitabine in a 2hrs infusion on: 
∀
day 1 if patients are participating in Part 1 or are randomized to the BI 836826-
GemOx treatment arm in Part2
or
∀
day 2 if patients are randomized to R-GemOx arm in Part 2.
Only one dose of oxaliplatin may be omitted during the trial.
Reduction of dose is allowed as per events described in table 6.2.2.1:1.

mg three times a day orally.
CMV reactivation during treatment should be treated according to institutional standards.
4.2.1.4.
Concomitant treatments
All concomitant therapies to provide adequate care may be given as clinically necessary. Any 
other anti-lymphoma therapy besides trial treatment is not allowed. All concomitant 
treatments should be recorded in the e-CRF except for vitamins or nutrient supplements. 
Trade name, indication and dates of administration of concomitant therapies will be 
documented. For parenteral nutrition during the trial, the components need not to be specified 
in detail. It should just be indicated as ‘parenteral nutrition’. If a patient needs general 
anesthesia, it will be sufficient to indicate ‘general anesthesia’ without specifying the details.
Systemic immune-suppressive therapy other than corticosteroids is not allowed during 
treatment. Short term pulsatile glucocorticoid medications may be used as clinically indicated 
to treat IRRs or autoimmune phenomena, at any dose. Long term (>5 days) daily oral steroid 
treatment may be administered at doses equivalent to prednisolone 20mg per day or below. 
Higher doses of daily steroid treatment should be discussed and agreed upon between 
investigator and sponsor.

*Normal size of lymph nodes and nodal masses on CT scan is defined as ≤1.5 cm in their 
greatest transverse diameter for nodes >1.5 cm before therapy. For previously involved nodes 
that were 1.1 to 1.5 cm in their long axis and more than 1.0 cm in their short axis before 
treatment must have decreased to ≤1.0 cm in their short axis after treatment. 
**For relapsed disease or progression, lymph nodes should be considered abnormal if the 
long axis is more than 1.5 cm regardless of the short axis. If a lymph node has a long axis of 
1.1 to 1.5 cm, it should only be considered abnormal if its short axis is more than 1.0 cm. 
Lymph nodes ≤1.0 x ≤1.0 cm will not be considered as abnormal for relapse or progressive 
disease.
The PET scan should be evaluated in accordance with recent guideline (R14-3383). The 
PET/CT scan should use a fixed display and color table scaled to standardized uptake value 
(SUV). The focal uptake in aggressive DLBCL is sensitive to bone marrow involvement and 
may make the need for a bone marrow biopsy unnecessary.
The PET scan should be evaluated with the use of the 5-PS which has been validated for use 
both as an interim and as end of treatment.
The 5-PS scores the most intense uptake in a site of initial disease, if present, as follows: 
1. No uptake 
2. Uptake ≤ mediastinum
3. Uptake > mediastinum but ≤ liver
4. Uptake moderately higher than liver
5. Uptake markedly higher than liver and/or new lesions

In addition, as written in the published reference (R14-3383) new areas of uptake, unlikely to 
be related to lymphoma, are marked by (X).
If the PET scan performed after 3 cycles, demonstrates a disease progression the patient has 
to be withdrawn from the trial treatment.

5.3.
ASSESSMENT OF SAFETY
5.3.1.
Physical examination & B symptoms
A physical examination including height (only at screening), weight and ECOG performance 
score as well as the tumor size determination (by palpation) will be performed at screening 
and at the time points specified in the Flow Chart 1, 2, 3. During the physical examination, 
the patient should be assessed for possible adverse events.
Patients may present with constitutional symptoms at baseline, which may improve on 
treatment, or may develop constitutional symptoms in the context of progression which may 
indicate the need for a subsequent therapy. 
All patients will be evaluated for lymphoma related B symptoms at the same time points 
when a physical examination is indicated in the Flow Charts 1, 2, 3. 
An evaluation of B symptoms will be based on the following parameters which have to be 
reported in the e-CRF:
∀
Weight loss ≥10% in 6 months or less
∀
Fever higher than 38.0°C
∀
Night sweats.
5.3.2.
Vital Signs
Vital signs (blood pressure, pulse rate and body temperature) will be recorded at every visit 
during screening, treatment and follow-up, before proceeding with any other clinical 
procedure and after at least 5 minutes of rest. Additional measures of vital signs need to be 
collected at the time of trial drug administration in order to detect possible IRRs which must 
be reported as AEs. In case of IRR, the investigator should decide whether to intensify or 
prolong the monitoring of vital signs and to adapt patient’s surveillance during subsequent 
infusions.
5.3.3.
Safety laboratory parameters
5.3.3.1.
General safety laboratory parameters
Blood samples and urine have to be collected at the time points specified in the Flow Chart 1,
2, 3 and before the infusion of trial medication, and will include the following analysis:

Pregnancy test
A serum pregnancy test needs to be obtained at screening and at 
EOT in female patients of childbearing potential. 
5.3.3.2.
Screening for laboratory evidence of TLS
To allow for early treatment in case TLS develops, vigilant monitoring after the first dose of 
BI 836826 or rituximab is recommended. During the first 24 hours after the start of the first 
dose of BI 836826 or rituximab the following laboratory parameters need to be checked at 
least once in patients who considered at risk for TLS, (e.g. large tumor burden, leukemic
manifestation of the lymphoma). The actual date and time of the blood samples should be 
recorded in the e-CRF. 
Testing for tumor lysis 
syndrome

Assessment of adverse events
5.3.6.1.
Definitions of AEs 
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily 
have to have a causal relationship with this treatment.
An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Serious adverse event
A SAE is defined as any AE which:
∀
results in death,
∀
is life-threatening,
∀
requires inpatient hospitalization or prolongation of existing hospitalization,
∀
results in persistent or significant disability or incapacity,
∀
is a congenital anomaly/birth defect,

∀
is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardize the patient and may require 
medical or surgical intervention to prevent one of the other outcomes listed in the above 
definitions.
Life-threatening in this context refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have caused death 
if more severe.
Every new occurrence of cancer will be reported as a SAE regardless of the duration between 
discontinuation of the drug and the occurrence of the cancer.
AEs considered “Always Serious”
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of AEs, which by their nature, can always be 
considered to be “serious” even though they may not have met the criteria of an SAE as given 
above.
The latest list of “Always Serious AEs” can be found in the Remote Data Capture (RDC). A 
copy of the latest list of “Always Serious AEs” will be provided to you upon request. These 
events should always be reported as SAEs as described in section 5.3.6.1.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. AESI 
need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, see section 5.3.7.
The following are considered AESIs in this trial:
∀
DLT
Any event that qualifies for DLT refer to section 5.3.8.
∀
IRR
IRRs CTCAE grade 3 -5 are defined to be AESIs.
∀
Late onset infections
Infections occurring during the “extended follow-up” period see Figure 5.3.7:1, which are 
clinically relevant and considered related to BI 836826 by the investigator, are to be 
reported as AESIs. 
∀
Hepatic injury  
Drug-induced liver injury (DILI) is under constant surveillance by sponsors and 
regulators and is considered an AESI in this trial. Timely detection, evaluation, and 
follow-up of laboratory alterations of selected liver laboratory parameters, is necessary to

distinguish an effect of the underlying malignancy on liver function from other causes. 
This is important for patient safety.
In patients with normal transaminases and bilirubin at baseline, a hepatic injury is defined 
by any of the following alterations of hepatic laboratory parameters: 
∀
an elevation of AST and/or ALT ≥3 fold ULN combined with an elevation of total 
bilirubin ≥2 fold ULN measured in the same blood sample, and/or
∀
marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN.
In patients with elevated transaminases and/or bilirubin at baseline in line with in- and 
exclusion criteria of this protocol, a hepatic injury is defined by the following alterations 
of hepatic laboratory parameters: 
∀
an elevation of AST and/or ALT ≥5 fold ULN combined with an elevation of total 
bilirubin ≥2 fold ULN measured in the same blood sample, and/or
∀
marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN.
Work-up as outlined in the “Drug-Induced Liver Injury (DILI)-checklist” will serve to 
confirm the initial abnormality, obtain a comprehensive history and medical assessment, 
assess the severity of liver injury, evaluate data for potential alternative causes and decide 
on management of trial drug. Follow-up of the potential DILI case should be initiated 
within 48 hours of the initial laboratory alert, or as soon as possible if timelines cannot be 
met. When performing all of the required examinations, the investigator may use clinical 
judgment, based on the patient’s disease, comorbidities, clinical situation, past viral 
infections and risk for reactivation, exposure, prior therapy for malignant disease, co-
medications and other factors as applicable. The sequence of tests in the DILI checklist 
may be used as guidance. The findings from the hepatic imaging (including comparison 
to prior imaging if available) must be made available as soon as possible as part of the 
adverse event reporting process and/or on the respective CRF pages. In the event the 
aetiology of the abnormal liver test results is not identified based on the imaging (e.g. 
biliary tract, pancreatic or intrahepatic pathology), the “DILI checklist” must be 
completed. Virus reactivation should be assessed by viral load and PCR testing where 
possible. Diagnostics for auto-immune hepatitis, Wilson’s disease and haemochromatosis 
can be completed at the end of all assessments, as these examinations will not change 
within a short time period but can be considered proof of a long persisting chronic 
condition. In case a laboratory parameter of the DILI checklist cannot be performed, the 
investigator should provide a comment including a brief assessment of the relevance of 
this parameter for the overall evaluation of DILI.
In case of clinical symptoms of hepatic injury (icterus, unexplained encephalopathy, 
unexplained coagulopathy, right upper quadrant abdominal pain, etc.) without lab results 
(ALT, AST, total bilirubin) available, the investigator should make sure these parameters 
are analysed, if necessary in an unscheduled blood test. Should the results meet the 
criteria of hepatic injury alert, the procedures described in the DILI checklist should be 
followed.
If the investigator determines any AESI is related to trial drug, the administration of the 
trial drug must be managed according to Table 6.2.2.1:1.

Any elevation of ALT and/or AST and total bilirubin qualifying as laboratory hepatic 
injury alert should lead to reflex testing on the initial blood sample. The reflex testing 
should include (if appropriate specimen is available):
∀
direct bilirubin
∀
acetaminophen level
∀
lactate dehydrogenase
∀
haptoglobin
∀
additional single PK sample should be drawn
∀
liver imaging should be performed within 48 hours of identifying a liver event
If the reflex testing at the local laboratory is initiated by the investigator the results 
need to be entered in the e-CRF.
Severity of AEs
The severity of adverse events should be classified and recorded in the e-CRF according to 
the CTCAE version 4.0 (R10-4848)
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Yes:
There is a reasonable causal relationship between the trial medication
administered and the AE.
No:
There is no reasonable causal relationship between the trial medication
administered and the AE.
Every adverse event must be assessed for causal relationship by the investigator. The 
investigator needs to determine according to their best ability whether given adverse event is 
related to BI 836826, rituximab and/or GemOx.
The causal relationship needs to be documented on the SAE form. The causal relationship 
also needs to be documented in the patient’s source data.
5.3.7.
Adverse event collection and reporting
AE Collection
The following must be collected and documented on the appropriate e-CRF by the 
investigator:

Figure 5.3.7:1 AE Collection
∀
From signing the informed consent onwards until FU for AEs visit all AEs (non-serious 
and serious), and AESIs ( this is the REP period).
∀
After the FU for AEs visit until the last per protocol contact, all those SAEs and AESIs 
which are considered related to trial medication .
∀
However, if only vital status information is collected for a patient after PD and/or new 
anti-lymphoma treatment, from then on until the patient’s participation in the trial ends,
the investigator does not need to actively monitor the patient for AEs.  Fatal AEs, relevant
SAEs and relevant AESIs, which the investigator may become aware of, should be
reported.
The FU for AEs / (end of REP) is scheduled 30-42 days after the last dose of trial medication
(last administration of Gemcitabine, Oxaliplatin, Rituximab or BI836826, whichever is the 
latest).All AEs which occurred during treatment up until FU for AEs visit are considered as 
“on treatment” AEs. Please see section 7.3.4. Events which occurred after the FU for AEs 
visit are considered “ post- treatment” AEs.
After the last per protocol contact, the investigator does not need to actively monitor patients 
for AEs. However, if the investigator becomes aware of SAEs or AESIs that occurred after 
the last per protocol contact, the SAEs and AESIs should be reported by the investigator to 
the sponsor if considered relevant by the investigator. The rules for AE reporting exemptions 
still apply.
AE reporting to sponsor and timelines
The investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours ) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). In 
specific occasions the investigator could inform the sponsor upfront via telephone. This does 
not replace the requirement to complete and fax the BI SAE form.

Information required
For each AE, the investigator should provide the information requested on the appropriate e-
CRF pages and the BI SAE form, e.g. onset, end date, intensity, treatment required, outcome, 
seriousness, and action taken with the investigational drug(s). The investigator should 
determine the causal relationship to the trial medication, and any possible interactions 
between the investigational drug(s) and a non-investigational product (NIMP) 
The following should also be recorded as an (S)AE in the e-CRF and SAE form (if 
applicable):
∀
Worsening of pre-existing conditions other than the underlying disease
∀
Changes in vital signs, ECG, physical examination and laboratory test results, if they are 
judged clinically relevant by the investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as baseline
conditions.
All (S)AEs, including those persisting after trial completion must be followed up until they 
have resolved, have been sufficiently characterized, or no further information can be 
obtained.
Pregnancy
In the rare case that a female subject participating in this clinical trial becomes pregnant after 
having taken trial medication, the investigator must report immediately (within 24 hours) the 
drug exposure during pregnancy (DEDP) to the sponsor’s unique entry point (country-
specific contact details will be provided in the ISF). The investigator must also report 
pregnancies that occurred in a female partner of a male subject. The Pregnancy Monitoring 
Form for Clinical Trials (Part A) should be used. 
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B). 
As pregnancy itself is not to be reported as an AE, in the absence of an accompanying SAE, 
only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form is to be 
completed. If there is an SAE associated with the pregnancy then the SAE has to be reported 
on the SAE form in addition.
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and B).
Exemptions to SAE Reporting
Progressive disease (PD) in oncology trials is a trial endpoint for analysis of efficacy. PD is 
exempted from reporting as a (S)AE.  Progression of the subject's underlying malignancy will 
be recorded in the appropriate pages of the e-CRF as part of efficacy data collection. Death 
due to PD is to be recorded on the appropriate e-CRF page and not on a SAE form.
Examples of exempted events of PD are:
•
Progression of underlying malignancy (Progressive disease PD): if PD is clearly 
consistent with the suspected progression of the underlying malignancy as defined by the 
respective response criteria.

•
Hospitalization/Procedures due solely to the progression of underlying malignancy (PD)
•
Clinical symptoms and/or signs of progression (with or without confirmation by objective 
criteria e.g. imaging, clinical measurement): if the symptom can exclusively be 
determined to be due to the progression of the underlying malignancy and does meet the 
expected pattern of progression for the disease under study.
When there is evidence suggesting a causal relationship between the drug and the event of 
progression of the underlying disease, the event must be reported as (S)AE in the eCRF and 
on the SAE form.
5.3.8.
Dose limiting toxicity for Part 1
The MTD will be defined on the basis of DLT observed during the first cycle, i.e. the first 14 
days of C1.
Any patient who has been replaced will not be considered evaluable for MTD determination.
The following adverse events will qualify as DLT:
∀
Any ≥G3 non hematologic adverse event considered related to any trial medication with 
the following exceptions:
•
Laboratory abnormalities that can be corrected with treatment within 48 
hours (for example: electrolyte abnormalities).
•
nausea, vomiting, diarrhea which resolve within 48hrs with adequate 
treatment
•
neuropathy considered related to oxaliplatin
•
IRR
∀
Any hematologic adverse event related to any trial medication defined as follows:
•
G4 neutropenia lasting >7 days despite growth factors support
•
Any febrile neutropenia which does not resolve within 48 hours with 
appropriate treatment (antibiotics, antifungal, antiviral agents and growth 
factors )
•
G4 thrombocytopenia lasting >7 days, or G3-4 thrombocytopenia with 
clinically significant bleeding
•
Failure to recover platelets (PLT) ≥ 75 x 109/L by 4 weeks after start of the 
cycle (meaning by D28 of the cycle)
•
Failure to recover neutrophils (ANC) ≥1.0 x 109/L by 4 weeks after start of 
the cycle (meaning by D28 of the cycle)
A DLT has to be reported as Adverse Event of Special Interest (AESI) section 5.3.6.1 .
The MTD will be defined on the basis of DLT observed during the first treatment cycle (D1 
to 14). However, for those patients who receive more than one cycle of BI 836826 plus 
gemcitabine and oxaliplatin, all adverse events corresponding to the above definition of DLT 
as well as other adverse events and laboratory assessments will be considered for the purpose

DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
5.4.1.
Assessment of pharmacokinetics
Blood samples will be collected for determining the pharmacokinetic parameters of BI 
836826 and exposure of gemcitabine and oxaliplatin in plasma. Oxaliplatin exposure will be 
assessed by means of the free platinum concentrations in plasma.
In addition samples will be collected for determining potential immunogenicity of BI 836826. 
The dates and the “start and stop” times of infusions along with additional information on 
respective infusion conditions, e.g. total dose and interruptions of infusion, should be 
documented for BI 836826, gemcitabine and oxaliplatin on all days of PK sampling.
These actual administration and sampling times will be used for determination of 
pharmacokinetic parameters.
Concentrations will be used for graphs and calculations in the format that is reported in the
bio-analytical report.
If data allow, the following pharmacokinetic parameters of BI 836826 will be evaluated using
noncompartmental analysis methods according to the internal BI Standard Operating
Procedure:
∀
Maximum measured plasma concentration of the analyte (Cmax)
∀
Area under the plasma concentration-time curve over the time interval from 0 to the 
time of the last quantifiable data point after drug administration (AUC0-tz)
∀
Area under the plasma concentration-time curve over the time interval from zero
extrapolated to infinity (AUC0-∞)
Others pharmacokinetic parameters can be calculated if considered relevant considering the 
available data.
5.4.2.
Methods of sample collection
For quantification of BI 836826 plasma concentrations, 3mL blood will be taken in an 
ethylendiaminetetraacetic acid (EDTA) anticoagulant blood drawing tube at the time points 
specified in Appendix 10.1. For the early time points on the day of drug administration the 
sample has to be taken from the opposite arm to the one where the infusion is/was 
administered in order to prevent contamination of blood samples with the infusion solution.

For quantification of gemcitabine and free platinum plasma concentrations, 3mL blood will 
be taken in an EDTA blood drawing tube at the time points specified in Appendix 10.1. For 
the early time points on the day of drug administration the sample has to be taken from the 
opposite arm to the one where the infusion is/was administered in order to prevent 
contamination of blood samples with the infusion solution. Since gemcitabine is highly 
unstable in blood and plasma, blood samples have to be stabilized with tetrahydrouridine
(THU) immediately after collection. To accurately determine free platinum concentrations, 
the blood samples have to be immediately centrifuged after collection. The resulting plasma 
has to be subsequently ultra-filtrated before freezing. The details are described in the ISF and 
it is important note that the ultra-filtration process must be started less than 20 minutes after 
blood draw. 
Correct, complete and legible documentation of drug administration and blood sampling 
times as well as adequate handling and identification of PK samples is mandatory to obtain 
data of adequate quality for the pharmacokinetic analysis.
Details about sample collection, preparation, required cryovials, labels, storage and shipment 
are described in the laboratory manual included in the ISF.
5.4.3.
Analytical determinations
BI 836826 will be determined using a validated enzyme-linked immuno assay (ELISA). 
Plasma concentrations of oxaliplatin will be determined as free platinum by a validated 
inductively coupled plasma mass spectrometry (ICP-MS) assay and gemcitabine 
concentrations will be determined by a validated liquid chromatography-tandem mass 
spectrometry (LC-MS/MS) assay. The procedures and specifications of the analytical 
methods are available at the determination site.
A detailed description of the assays will be available prior to the start of sample analysis.

APPROPRIATENESS OF MEASUREMENTS
Determination of MTD of BI 836826 is based on toxicities graded according to CTCAE
version 4.0 (R10-4848). The CTCAE criteria are commonly used for the assessment of 
adverse events in cancer patients. In the randomized part of the trial the response is assessed 
according to the International recommendation for lymphoma which is well established (R10-
1462, R14-3383, R14-3387).

6. INVESTIGATIONAL PLAN
6.1.
VISIT SCHEDULE
The allowable time windows for visits are included in the Flow Charts 1, 2, 3.
∀
Screening period is 14 days to 1 day prior C1D1.
∀
The planned duration of a treatment cycle is 14 days (+ maximum 3 days from cycle 2 
in case of delayed D8). In case of toxicity, the start of the next cycle may be delayed 
by maximum of 14 days to allow for recovery.
∀
Day 1, 2 and 8 of cycle 1 must be strictly respected. Only C1D11 can be done with -1 
day window (applicable only with BI 836826-GemOx). From Cycle 2, D8 can be 
delayed by maximum 3 days.
∀
EOT:
o
If a patient has been prematurely withdrawn from treatment (i.e. earlier than 
the 6th cycle), EOT must be performed within 14 days after last dose (last 
administration of Gemcitabine, Oxaliplatin, Rituximab or BI 836826, 
whichever is the latest).
o
If a patient completed all 6 cycles according to protocol, EOT must be 
performed at the earliest 30 days and no later than 42 days after the last dose
(last administration of Gemcitabine, Oxaliplatin, Rituximab or BI836826, 
whichever is the latest).
∀
FU AEs visit: The information collected at this visit should include all new AEs that 
occurred after the last dose and a follow-up of adverse events ongoing at the time of 
the last dose or EOT visit. 
o
If a patient has been prematurely withdrawn from treatment, the FU for AEs 
visit can be performed on site 30-42 days after the last dose. 
o
If a patient completed the 6 cycles according to the protocol, the FU for AEs 
visit can be scheduled at the same time point as EOT visit. 
∀
Follow-up visits (FU): After the FU for AEs, the patient will be followed for disease 
assessment/vital status (remission/progression/death/new anti-lymphoma treatment) 
and drug related SAEs and AESIs. These FU visits should take place every 3 months 
for the first year after FU for AEs visit, and then every 6 months until death, patient is 
lost to follow-up, patient withdraws consent for further follow up or the end of trial is 
reached. FU may be performed by telephone interview in case the patient is unable to 
visit the investigator

Screening period
Patients who failed screening may repeat the screening once after discussion between the 
investigator and sponsor providing that reasons for screening failure were reversible and have 
been resolved.
SAEs and /or AESI occurring in patients who are classed as screening failures, ( i.e. those  
patients who did not receive any trial medication), are to be reported if the Investigator

considers the SAEs and /or AESI to be related to the screening procedure. SAEs and /or 
AESI during the screening period are to be reported according to standard procedures.
A log of all patients enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not
6.2.2. 
Treatment period(s)
A treatment cycle is defined as 14 days, with the start of next cycle on day 15 (from cycle 2, 
D8 can be delayed by maximum 3 days, meaning that the cyle could be up to 17 days, with 
the start of the next cycle on day 18). However if it is medically indicated a cycle may be 
postponed by maximum of 14 days due to toxicity reasons. Any additional visits (not 
foreseen by flow charts) will be recorded in the e-CRF.
In Part I, Cycle 1, no dose reduction or dose skipped is allowed.
In Part 1 and 2 in Cycle 1, there is the need for hospital stay for a minimum of 24 hours for 
PK sampling and safety monitoring. Please see Flowchart 1and2 and Appendix 10.1.
Patients may continue trial medication for maximum of 6 cycles. Patients who develop PD, or 
toxicity or who are considered intolerable, or withdraws consent, are to discontinue the trial 
according to the discontinuation rules described in section 3.3.4.
Please refer to section 4.1.4for drug administration.
6.2.2.1. 
Criteria to continue next treatment cycle (C2-6) and guidance to dose 
reduction 
The following criteria need to be fulfilled on D1 of each treatment cycle for Cycles 2-6:
∀no active infection
∀no evidence of progressive disease 
∀recovery from any AE except lymphopenia to ≤ G1, or to baseline
∀peripheral blood counts recovery defined as: 
PLT ≥ 75 x 10
9/L
ANC ≥1.0 x 109/L
Patients who experienced toxicity suspected as DILI need to demonstrate recovery of 
AST/ALT/bilirubin values as defined in section 5.3.6.1.
Guidance for dose reduction:
∀BI 836826:
The following criteria need to be fulfilled on D8 of each treatment cycle for Cycles 2-6, prior 
to start of the infusion with BI 836826:
In case elevations of AST and or ALT > 3 x ULN are considered drug related 
or related to a hepatic injury, a decline to ≤ 3 x ULN has to be documented 
prior to administration of the next dose of BI 836826. In case an elevation of 
bilirubin to >1,5 x ULN is considered drug related or related to a hepatic

injury, a decline to ≤ 1.5 x ULN or baseline (for patients with elevated levels 
at trial entry) has to be documented prior to administration of the next dose of 
BI 836826. 
From cycle 2, the infusion can be delayed by maximum 3 days, until D11. In that case, the 
next cycle should not start before at least 7 days between the BI 836826 infusion and the next 
D1.
If needed, the dose of BI 836826 should be omitted. If more than one dose of BI 836826 is 
skipped, the patient must be removed from the study.
Reduction of dose is allowed as per events described in table 6.2.2.1:1.
∀
Rituximab:
No dose reduction or skipped dose of rituximab is allowed.
∀
Oxaliplatin:
Only one oxaliplatin dose can be omitted for toxicity reasons during the duration of the trial
(6 cycles). If due to toxicity, related to oxaliplatin (Table 6.2.2.1:1), a patient is unable to 
receive oxaliplatin, the treatment can continue with BI 836826-Gem, or R-Gem for one cycle. 
If at the time of the next cycle the patient still cannot receive oxaliplatin due to oxaliplatin 
related toxicities, this patient needs to be withdrawn for toxicity reasons, and will not be 
allowed to re-enter the trial.
Reduction of dose is allowed as per events described in table 6.2.2.1:1.
∀
Gemcitabine:
No dose reduction or skipped dose of gemcitabine is allowed.
The criteria below are serving as basic guidance to investigators. They should not replace a 
sound clinical judgment in case of occurrence of other serious toxicities not listed in the table 
below.

days or more, oxaliplatin was to be stopped until symptoms improved and then restarted at a 
dose of 75 mg/m². In the event of pharyngolaryngeal dysesthesia, the duration of the 
oxaliplatin infusion was to be prolonged from 2 to 6 h.
6.2.2.2.
Monitoring for infusion-related reactions
Close monitoring of the patients during and after the infusions of BI 836826 or rituximab in 
combination with GemOx is required for the evaluation of IRR. The monitoring includes:
∀
During the first infusion of BI 836826 the patients are required to be hospitalized under 
close surveillance with access to intensive care for at least 24 hours.
∀
Subsequent infusions of BI 836826 may be administered in outpatient facilities with 
access to intensive care unit.
∀
The infusions of rituximab can be administered in an outpatient setting if well tolerated.
∀
Frequent measurements and documentation of blood pressure and heart rate (see section 
5.3.2.
6.2.2.3.
Handling of infusion-related reactions
In case of an IRR, the infusion has to be stopped immediately for ≥ G2 reactions. Appropriate 
actions depending on the type and severity of the reaction should be taken according to best 
medical judgment and local guidelines. Supportive therapy including steroids may be used as 
clinically indicated. If IRR has been managed successfully, and if in the investigators’ 
judgment the infusion can be re-started at lower rate, the total time between original start and 
end of infusion cannot exceed 24 hrs. If infusion cannot be completed within 24 hours the 
remaining solution needs to be discarded, and the total dose received appropriately 
documented in e-CRF.
IRR should be reported as other AEs according to CTCAE version 4.0 with the term infusion 
related reaction. Together with this term the individual symptom, e.g. chills should also be 
grade according to CTCAE. IRRs are defined to be AESIs if they are classified CTCAE 
grade 3-5. AESIs have to be reported in an expedited manner according to SAE-reporting 
(see section 5.3.7).
The following recommendations for the management of IRRs may be considered by the 
investigator as guidance (see also table 6.2.2.1:1):
∀
In the case of G1 IRR, the infusion rate of BI 836826 should be reduced, e.g. to 50% of 
the target rate, or the infusion should be temporarily interrupted and resumed as soon as 
considered clinically manageable by the investigator.
∀
In the case of G2-3 IRR, the infusion with BI 836826 should be stopped immediately. 
Only in case all symptoms have resolved, administration of BI 836826 may be resumed at 
a slower infusion rate, e.g. of 50% of the target rate, and increase the infusion rate as 
tolerated to the target rate.
∀
In the case of G4 IRR, the infusion has to be stopped immediately. These patients should 
not be re-exposed to BI 836826 after the event.

6.2.2.4.
Laboratory analyses:
The safety laboratory analyses (see section 5.3.3) will be performed at the investigator’s site, 
i.e. local hospital laboratories. The certification/accreditation for each laboratory or evidence 
that it participates in an established quality program must be provided by the investigator and 
filed in the sponsor’s and in the local ISF. The normal ranges of each test performed are to be 
documented in e-CRF.
Blood samples for pharmacokinetic analyses (PK), and flow cytometry (lymphocyte immune-
phenotyping) 
 will be shipped to a central laboratory in both 
Part 1 and 2.
 
 
6.2.2.5.
Disease assessments (PET-CT) 
PET/CT Scan of neck, thorax, abdomen, and pelvis has to be performed at:
∀
Baseline PET/CT scan : up to 28 days prior to C1D1
∀
Interim  PET/CT scan : after end of C3, i.e. prior to C4D1 infusion
∀
Final PET/CT scan: 3-6 weeks after the last dose if 6 cycles have been completed.
In Part 1, image acquisition and readings will be performed locally, and appropriate data and 
measurements will be entered into e-CRF. 
In Part 2 image acquisitions will be performed locally, however the images will be sent to an 
appointed vendor for central readings, and central archiving. A copy of the images are to be 
retained at the site. Local readings should be used for treatment decisions (i.e. discontinuation 
from trial participation due to PD) local results are to be entered in e-CRF.
6.2.2.6.
Tumor lysis syndrome (TLS)
During the first 24 hours after the start of the first dose of BI 836826 or rituximab, laboratory 
parameters need to be checked at least once in patients who considered at risk for TLS (e.g. 
large tumor burden, leukemic manifestation of the lymphoma) (see section 5.3.3.2). 
In case of clinical or laboratory signs of TLS appropriate treatment and hydration needs to be 
instituted immediately according to local standards.
6.2.3.
End of Treatment
For patients completing all 6 cycles: the end of treatment visit and should be done at the 
earliest 30 days and no later than 42 days after the last dose (last administration of 
Gemcitabine, Oxaliplatin, Rituximab or BI836826, whichever is the latest).
If a patient is prematurely withdrawn from treatment (i.e. earlier than the 6th cycle) an EOT 
visit should be performed within 14 days after last dose (last administration of Gemcitabine, 
Oxaliplatin, Rituximab or BI836826, whichever is the latest).

6.2.4.
Follow-Up for AEs
A Follow up visit for AEs collection needs to be performed between 30- 42 days after the last
dose (last administration of Gemcitabine, Oxaliplatin, Rituximab or BI836826, whichever is 
the latest). The information collected at this visit should include all new AEs that occurred 
after the last dose and a follow-up of adverse events ongoing at the time of the last dose.
If a patient completes the 6 cycles according to the protocol the FU for AEs visit can be 
scheduled at the same time point as EOT visit. 
If a patient has been prematurely withdrawn from treatment, the FU for AEs visit can be 
performed on site 30-42 days after the last dose. 
6.2.5.
Follow Up Period and Trial Completion
After the FU for AEs, the patient will be followed for disease assessment/vital status 
(remission/progression/death/new anti-lymphoma treatment) and drug related SAEs and 
AESIs. These FU visits should take place every 3 months for the first year after FU for AEs 
visit, and then every 6 months until death, patient is lost to follow-up, patient withdraws 
consent for further follow up or the end of trial is reached. FU may be performed by 
telephone interview in case the patient is unable to visit the investigator
If patient progresses or relapses, only data on the new anti-lymphoma treatment and survival 
will be collected.
Prior to primary and final analyses, all applicable patients will be contacted for vital status  
regardless of whether the next FU visit is due or not.
The end of the trial is defined as when the last ongoing patient has completed treatment and 
has been followed for at least a year or when at least 50% of the patients have died, 
whichever occurs last.

7. STATISTICAL METHODS AND DETERMINATION OF SAMPLE
SIZE
7.1.
STATISTICAL DESIGN MODEL
This trial will be conducted as an open-label trial in two parts. The primary objective of the 
Part 1 (Phase Ib) is to determine the dose of BI 836826 for the combination with GemOx 
using the classical 3+3 design (R04-0569) based on the number of patients with DLTs and 
the resulting MTD. 
In the second randomized part of the trial safety and efficacy of the combination BI 836826-
GemOx vs. R-GemOx will be evaluated. The primary endpoint for efficacy is OR by using 
PR+CR rates, analyzed when the last patient in the trial has completed 6 cycles of trial 
medication, or has been withdrawn for other reasons. 
Only descriptive and exploratory analyses are planned and no formal statistical testing will be 
performed.
7.2.
NULL AND ALTERNATIVE HYPOTHESES
No formal hypothesis testing is planned in this trial. This is an exploratory Phase Ib/II trial 
with the main objective of treatment effect estimation. The primary endpoint for Part 2 will 
be overall response analyzed by PR+CR rate. All analysis and p-values provided need to be 
understood in an exploratory way.
7.3.
PLANNED ANALYSES
All patients who have received any amount of trial drug of BI 836826 or rituximab or 
gemcitabine or oxaliplatin will be included into safety analyses. All patients randomized for 
the Part 2 of the trial will be included in all efficacy analyses, using the intent-to-treat 
approach. Every effort will be made to evaluate response and progression for all patients who 
receive treatment, including those who discontinue prematurely.
During Part 1, cohorts of patients treated with BI 836826 in combination with GemOx will be 
evaluated continuously based on the totality of the safety data in order to determine the 
recommended BI 836826 dose for Part 2 of the trial. Results from data snapshots will be 
provided as needed to the trial team and involved investigators to support the determination 
of the dose for the randomized Part 2 of the trial. 
Summary outputs of efficacy analyses will include all patients entered in Part 2 of the trial. 
Both treatment arms in Part 2 will be compared.
Safety analyses will be summarized separately for patients treated in Part 1 and Part 2 of the 
trial.
No per protocol set will be used in the analyses. However potential important protocol 
violations will be summarized and violations of inclusion and exclusion criteria will be

provided in a subject data listing. The Core Trial Statistical Analysis Plan will specify the 
potential important protocol violations in detail.
The analyses of all primary, secondary and further endpoints in Part 1 and  Part 2 will be 
performed when the last patient entered in Part 2 has completed 6 cycles of trial medication 
or has been withdrawn for other reason; a CTR will be written at this time point.
The final CTR will be written at the end of the trial.
7.3.1.
Primary endpoint analyses
Part 1: The primary endpoint of the Phase Ib is to determine the MTD of BI 836826 in 
combination with GemOx analyzed via the number of patients with DLTs during the MTD 
evaluation period. In order to identify the MTD, the number of patients with DLTs at each 
dose level will be presented.
Part 2: The primary endpoint of the randomized Phase II is overall response analyzed by the 
PR+CR rate. The 95% confidence interval will be provided for the PR and CR rate in each 
arm. Comparisons between treatment groups will be performed using the Suissa-Shuster 
exact test (including the Berger-Boos modification), for which an exploratory p-value will be 
provided.
7.3.2.
Secondary endpoint analyses
Part 1: PK endpoints will be analysed as described in Section 7.3.5. Overall response by 
investigator’s assessment will be analysed descriptively in terms of the OR rate.
Part 2:
Complete remission
Best overall response is the best response (CR, PR, stable disease (SD) or PD) with respect to 
all time points. Complete remission is defined as CR and will be analyzed descriptively and 
compared between the two treatment arms.
Frequency distributions and other descriptive statistical measures will be used to examine this 
endpoint.

period in the Part 1 as well as during the on-treatment period in Part 1) as well as the 
incidence and intensity of adverse events, graded according to CTCAE version 4.0 and 
reported according to BI standards, laboratory parameters and vital signs will be evaluated. 
The safety analysis will be descriptive and exploratory and results for the Part 1 and Part 2 
will be presented separately. No hypothesis testing is planned. 
Adverse events will be coded using the Medical Dictionary for Drug Regulatory Activities 
(MedDRA) coding dictionary. Standard BI summary tables and listings will be produced.
The overall incidence and intensity of adverse events, as well as relatedness of adverse events 
to treatment with BI 836826 will be reported for all dose cohorts in Part 1 and for both 
treatment arms in Part 2. SAEs, fatal AEs and AESIs will be tabulated. In addition, events 
leading to treatment discontinuation will be examined.
Events that start from any administration of trial medication until 30 days after the last 
administration of any trial medication will be considered as having occurred “on treatment” 
see section 5.3.8.
In general, adverse events occurring after the FU for AEs visit (after REP) will be attributed 
to the post-treatment period and will be presented separately. However, post-treatment events 
will be examined to determine whether they need to be combined with on-treatment events in 
an additional table.
Descriptive statistics will be used to describe changes in laboratory tests over time. In 
addition, all abnormalities of potential clinical significance will be reported. Treatment 
groups will be compared descriptively with regard to distribution parameters as well as with 
regard to frequency and percentage of patients with abnormal values or clinically relevant 
abnormal values.
Vital signs, physical examinations, or other safety-relevant data observed at screening, 
baseline, during the course of the trial and at the end-of-trial evaluation will be assessed with 
regard to possible changes compared to findings before start of treatment.
7.3.5.
Pharmacokinetic analyses
Refer to Section 5.5.1 for PK parameters to be calculated.
Plasma concentrations will be plotted graphically versus time for all subjects as listed in the
drug plasma concentration-time tables. For the presentation of the mean profiles, the 
arithmetic and geometric mean and the planned blood sampling times will be used. If the 
actual sampling time deviates significantly from the planned time, the corresponding plasma
concentration will be excluded from the calculation of descriptive statistics.
The following descriptive statistics will be calculated for analytic concentrations as well as 
for all pharmacokinetic parameters: N, arithmetic mean, standard deviation, minimum, 
median, maximum, arithmetic coefficient of variation, geometric mean, and geometric 
coefficient of variation. The data format for descriptive statistics of concentrations will be 
identical with the data format of the respective concentrations. The descriptive statistics of 
pharmacokinetic parameters will be calculated using the individual values with the number of

decimal places as provided by the evaluation program. Then the individual values as well as 
the descriptive statistics will be reported with three significant digits in the clinical trial 
report.
7.3.5.1.
Plasma concentration - time profiles
Concentration data identified with no sample available (NOS), no valid result (NOR), not 
analyzed (NOA), and below the limit of quantification (BLQ) will be ignored and not 
replaced by zero at any time point (applies also to the lag Phase including the pre-dose 
value). Descriptive statistics of concentrations at specific time points will be calculated only 
when at least 2/3 of the individuals have concentrations within the validated concentration 
range. The overall sample size to decide whether the “2/3 rule” is fulfilled will be based on 
the total number of samples intended to be drawn for that time point (i.e. BLQ, NOR, NOS, 
NOA are included).
7.3.5.2.
Pharmacokinetic assessment
In the non-compartmental analysis, concentration data identified with NOS, NOR, and NOA 
will not be considered. All other BLQ values of the profile will be ignored.
If the pre-dose concentration before the first dose is less than or equal to 5% of Cmax value in 
that subject, the subject’s data without any adjustments can be included in all 
pharmacokinetic measurements and calculations (i.e. the pre-dose value will not be changed 
to zero). If the pre-dose value is greater than 5% of Cmax, the subject should be dropped from 
all statistical evaluations. The individual pharmacokinetic parameters can be calculated and 
listed separately. 
Every effort will be made to include all concentration data in an analysis. If not possible, a 
case to case decision is required whether the value should only be excluded from half-life 
estimation or the complete analysis. 
∀
If a concentration is only excluded from half-life determination, it will be used for all 
other calculations (e.g. descriptive statistics) and for graphical presentation.
∀
If a concentration value is excluded from all calculations, it will not be presented 
graphically or used for the calculation of descriptive statistics and parameter 
determination. However the excluded concentration itself will be listed in the clinical trial 
report associated with an appropriate flag.
Descriptive statistics of parameters are calculated only when at least 2/3 of the individual 
parameter estimates of a certain parameter are available. If the actual sampling time will not 
be recorded or will be missing for a certain time point, the planned time will generally be 
used for this time point instead. Pharmacokinetic parameters which cannot be determined will 
be identified by "not calculated" (NC).

7.4.
INTERIM ANALYSES
The dose selection for Part 2 will be based on the safety and PK data after the last patient in 
Part1 has completed cycle 1. After the discussion with the treating investigators the decision 
will be documented and shared with the investigators.
Details for the evaluations to be performed will be outlined in the trial statistical analysis plan
(TSAP).
During Part 2 of the trial regular monitoring by the internal DMC will be performed to ensure 
the positive benefit-risk for the patients. See section 3.1.1
7.5.
HANDLING OF MISSING DATA
In general, missing data will not be imputed. Every effort will be undertaken to obtain the 
date of progression or remission for patients known to have progressed or experienced a 
remission and to obtain complete information on all AEs. Consequently no missing data will 
be imputed unless otherwise specified.
For partial or missing AE onset and/or end dates, BI internal rules will be applied for 
imputation.
7.6.
RANDOMISATION
Part 1:
No randomization will be performed. Patients will be assigned into escalating dose groups by 
order of admission into the trial.
Part 2:
In the second part of the trial patients will be randomized in a 1:1 ratio to BI 836826-GemOx 
or R-GemOx.
Patients will be randomized in blocks to one of the treatment groups. Approximately equal 
numbers of patients will be randomized to each treatment group. Randomization will be 
performed using IRT. BI, Clinical Trial Support Group or a CRO appointed by the sponsor 
will provide the randomization lists using a validated randomization number generating 
system, which involves a pseudo-random number generator so that the resulting treatment 
will be both reproducible and non-predictable. The block size will be documented in the 
CTR. Access to the codes will be controlled and documented.
7.7.
DETERMINATION OF SAMPLE SIZE
7.7.1.
Part 1
In the first part (Phase Ib) of the trial the classical 3+3 design will be used. The overall 
number of the patients for the 3+3 design is not fixed. 
Up to-33 will be enrolled. The classical 3+3 design allows for flexibility and additional 
patients might be recruited to determine the BI 836826 dose to be used in the combination BI 
836826-GemOx.

7.7.2.
Part 2
For the determination of sample size in the second part we assume as a best case scenario a 
target ORR of the BI 836826-GemOx combination of 81% and for the reference combination 
R-GemOx an ORR of 61%. In this case the true treatment difference is 20%. Due to 
stochastic nature of the process the true treatment difference is usually not the same as the 
treatment difference observed in the trial. Therefore we evaluate the probability to observe a 
difference of at least 10% under the assumption that the true difference lies somewhere 
between 0% and 20% (see table 7.7.2:1).

Results are based on 1000000 simulations in SAS version 9.2.
If the true difference is 20%, the probability to observe a treatment difference of at least 10% 
should be above 80% in order to provide sufficient credibility for the trial results. This 
probability is 87.2% with 60 patients per arm. At the same time if there is no difference in 
ORR between the treatments, the probability to observe a treatment difference of at least 10% 
by chance in the trial with 60 patients per arm is very low (11.2%).
The sample size of 60 patients per arm and the requirement that the observed treatment 
difference is at least 10% allows clear differentiation between these two scenarios and 
therefore is considered adequate for efficacy evaluation in the second part of this trial.

records, depending on the trial; current medical records must also be available.
For the e-CRF, all data need to be derived from source documents.
8.3.2.
Direct access to source data and documents
The investigator / institution will permit trial-related monitoring, audits, IRB/IEC review and 
regulatory inspection, providing direct access to all related source data / documents. e-CRF 
and all source documents, including progress notes and copies of laboratory and medical test 
results must be available at all times for review by the sponsor’s Clinical Research Associate 
(CRA), auditor and inspection by health authorities (e.g. Food and Drug Administration 
(FDA)). The Clinical Research Associate (CRA) / on site monitor and auditor may review all 
e-CRF, and written informed consents. The accuracy of the data will be verified by reviewing 
the documents described in section 8.3.1. The sponsor will also monitor compliance with the 
protocol and ICH GCP.

8.3.3.
Storage period of records
Trial site(s):
The trial site(s) must retain the source documents and essential documents for a period 
defined in the trial site’s contract with the sponsor.
Sponsor:
The sponsor must retain the essential documents according to the sponsor’s SOPs.
When it is no longer necessary for the trial site to retain the source documents and essential 
documents, the sponsor must notify the head of trial site.
8.4.
LISTEDNESS AND EXPEDITED REPORTING OF ADVERSE EVENTS
8.4.1.
Listedness
To fulfil the regulatory requirements for expedited safety reporting, the sponsor evaluates 
whether a particular adverse event is "listed", i.e. is a known side effect of the drug or not. 
Therefore, a unique reference document for the evaluation of listedness needs to be provided. 
For BI 836826 this is the current version of the Investigator’s Brochure. 
For the comparator, rituximab, the SmPC of the originator Mabthera will be used. For the 
non-investigational trial medication, gemcitabine and oxaliplatin, the  SmPCs of the 
originator products GEMZAR and Eloxatin will be used will be used. The current versions of 
these reference documents are to be provided in the ISF. 
8.4.2.
Expedited reporting to health authorities and IEC / IRB
Expedited reporting of serious adverse events, e.g. suspected unexpected serious adverse 
reactions (SUSAR) to health authorities and IEC / IRB, will be done according to local 
regulatory requirements.
8.5.
STATEMENT OF CONFIDENTIALITY AND PATIENT PRIVACY
Individual patient medical information obtained as a result of this trial is considered 
confidential and disclosure to third parties is prohibited with the exceptions noted below. 
Patient confidentiality will be ensured by using patient identification code numbers.
Data protection and data security measures are implemented for the collection, storage and
processing of patient data in accordance with the principles 6 and 12 of the WHO GCP
handbook.
Treatment data may be given to the patient’s personal physician or to 
∀
 appropriate medical personnel responsible for the patient’s welfare. Data generated as 
a result of the trial need to be available for inspection on request by the participating 
physicians, the sponsor’s representatives, by the IRB / IEC and the regulatory authorities.

8.6.
END OF TRIAL
The end of the trial is defined as when the last ongoing patient has completed treatment and 
has been followed for at least a year or when at least 50% of the patients have died, 
whichever occurs last.
The IEC / competent authority in each participating EU member state needs to be notified 
about the end of the trial or early termination of the trial.
When the trial is completed, the investigator should inform the head of the trial site of the 
completion in writing, and the head of the trial site should promptly inform the IRB and 
sponsor of the completion in writing.
8.7.
PROTOCOL VIOLATIONS
The investigator should document any deviation from the protocol regardless of their reasons. 
Only when the protocol was not followed in order to avoid an immediate hazard to trial 
subjects or for other medically compelling reason, the principal investigator should prepare 
and submit the records explaining the reasons thereof to the sponsor, and retain a copy of the 
records.
8.8.
COMPENSATION AVAILABLE TO THE PATIENT IN THE EVENT OF 
TRIAL RELATED INJURY
In the event of health injury associated with this trial, the sponsor is responsible for 
compensation based on the contract signed by the trial site.
