8
ECG, bone marrow aspiration, 
 tests will be performed at EOFT only if the patient has 
completed at least 2 cycles (e.g. received 4 administrations) since the EOT visit.
9
Concomitant therapy during FU is collected only if indicated for treatment of adverse event.
10
Bone marrow aspirate to assess efficacy before 5th and 9th administrations (i.e., BM performed on Day 1 (+/- 1) of 
cycles 3 and 5 and treatment started on day 1 (up to +3 days) of cycles 3 and 5) (see Section 5.1.2).  
 
11
Only one sample to be collected at the time of PD or the time of initiation of other anti-leukemia therapy, which 
may be at the EOT/EOFT, if PD or initiation of other anti-leukemia therapy occurs during treatment, or during 
follow-up. If the patient is non-progressing/not receiving other anti-leukemia therapy at the end of follow-up or the 
trial, the sample will be obtained at the last follow-up visit for this patient.
 
 
  
 
 
16
Can be performed up to 2 days prior to this visit.
17
After the 8th infusion, at the end of treatment visit, patients will be evaluated to determine if they have clinical 
benefit, as defined by IWG objective response (PR, CRi or CR) or subjective response (in the absence of objective 
response) and are tolerating the infusions well and who would like to continue to receive infusions until PD or 
other criteria for withdrawal are met as noted in Section 3.3.4.1.  For each infusion past the 8th administration, 
patients will continue to be assessed after each cycle for clinical benefit (objective or subjective response), and that 
they are tolerating the infusions well and would like to continue until PD or other criteria for withdrawal are met as 
noted in Section 3.3.4.1.

INTRODUCTION
1.1
MEDICAL BACKGROUND
Acute myeloid leukemia (AML) is a heterogeneous clonal disorder of hematopoietic
progenitor cells and represents the most common malignant myeloid disorder in adults, with a 
prevalence of 3.8 cases per 100,000 rising to 17.9 cases per 100,000 adults aged 65 years and 
older (R07-2768). The median age at presentation is about 70 years, and three men are 
affected for every two women. Without therapeutic intervention the disease progresses and 
leads to death within months after initial diagnosis (R07-2768).
Genetic alterations in leukemic cells constitute the most important factor for the prognosis of 
AML (R07-2768, R07-2770, R07-2774). AML patients are classified in groups of favorable, 
intermediate, and unfavorable risk. Other factors with impact on prognosis are age, 
performance score, white blood cell count, blood chemistry disturbances and de-novo versus 
secondary AML.
Intensive treatment approaches for AML with curative intention include two phases. The 
first, induction treatment, most commonly consists of cytarabine and an anthracycline, is 
aiming to reach a CR. The second phase, post-remission treatment, is aiming to consolidate 
remission. AML patients under the age of 60 years achieve complete remission rates of up 
to75 % following intensive treatment regimens, while AML patients over 60 years of age 
(referred to as elderly patients) have a 40 - 60 % chance of CR when receiving intensive 
remission induction treatment (R07-2767).
While the majority of younger AML patients receive intensive treatment, a substantial 
number of elderly patients are considered ineligible for this treatment approach 
(R07-2773, R07-2854). Therefore, the CR rates up to 60 % reported in elderly previously 
untreated AML patients receiving intensive treatment are by no means representative of the 
entire group of elderly AML patients. For AML patients considered ineligible to receive 
intensive treatment investigational treatments is widely regarded as the preferred therapeutic 
option (R07-2769, R07-2772). With these non-approved drugs CR rates up to 20 % are 
observed in randomized Phase III trials. Although patients who are considered as ineligible 
for intensive treatment constitute a generally accepted subgroup of AML patients, no 
validated criteria are defined to judge a patient's eligibility for intensive treatment 
(R07-2771). The assessment of eligibility for intensive treatment is performed regularly for 
every single patient based on the specialised physician's clinical experience and the 
comprehensive review of factors such as patient age, performance score, organ dysfunctions 
and co-morbidities, as well as the patient's informed decision.
The median overall survival (OS), for patients not achieving a CR is <1 year, even with best 
palliative treatment. Even for patients who have received induction and consolidation 
treatment the OS and cure rate are poor: Over 60 % will die due to their disease within 
5 years. The risk of leukemic relapse along with the poor prospects of long-term survival 
after a relapse calls for novel therapeutic strategies to maintain CR in AML.

AML patients in CR who have been initially diagnosed with non-favorable genetics and 
either have received induction and consolidation treatment and are not candidates for 
allogeneic hematopoietic stem cell transplantation (e.g. no donor available, not eligible/fit 
enough) or have received an allogeneic hematopoietic stem cell transplantation have a very 
high risk to relapse. For those patients no standard therapy to maintain the CR is currently 
available. 
For refractory or relapsed AML patients, outside of treatment in clinical trials, re-induction 
followed by allogeneic stem cell transplantation is the most common regimen. However 
many are not eligible for such an intensive treatment. For those patients with refractory or 
relapsed AML ineligible for intensive treatment, or for those with refractory or relapses 
disease after allogeneic stem cell transplantation, no approved or standard treatment is 
available. 
Evidence that targeting of CD33 can result in clinical benefit for patients suffering from 
AML is provided by the unconjugated, humanized IgG1 monoclonal antibody lintuzumab 
(SGN-33, HuM195) which showed signs of clinical efficacy as monotherapy in a Phase I 
clinical trial in relapsed / refractory AML patients with an objective response rate (ORR) 
of 17 % (R11-1481). Objective response was defined as either CR, CRi or PR.
Lintuzumab was also explored in a Phase I study in patients with acute promyelocytic 
leukemia (APL) after remission induction. Multiple doses of lintuzumab could be 
administered safely and appeared to eliminate minimal residual disease detectable by RTPCR 
in some patients. (R11-4695)
Currently, major efforts are focused on the improvement of the therapy in these subgroups of 
patients with unfavourable prognosis.
1.2
DRUG PROFILE
BI 836858 is a fully human IgG1 antibody specific for human CD33 which is Fc-engineered 
for increased binding to FcRIIIa. Please see full details in latest version of Investigator’s 
Brochure (c02324887-03).
CD33 is a myeloid differentiation antigen which is expressed on the cell surface of non-
malignant leukocytes of the myeloid lineage and with high frequency on malignant cells in 
AML, chronic myeloid leukemia and myelodysplastic syndrome (R11-1467, R11-1468, 
R11-1470, R11-2960). In addition to expression on malignant myeloid blast cells, CD33 
expression was reported for leukemic stem cells (R11-1469). For normal leukocytes, CD33 
expression was reported for monocytes, macrophages, dendritic cells, and to a lower extent, 
granulocytes (R11-1467), but not for CD34+CD38- hematopoietic stem cells in the bone 
marrow (R11-1469). Based on the expression profile of CD33, transient pharmacodynamic 
effects of CD33 antibody treatment on CD33 positive normal cell types may be expected.

BI 836858 is Fc-engineered for increased binding to FcRIIIa, which results in increased 
antibody dependent cellular cytotoxicity (ADCC) activity of BI 836858 as compared to a 
non-Fc-engineered IgG1-type of antibody. The ADCC activity of BI 836858 was assessed on 
a panel of AML-derived cell lines and primary AML cells and compared to the ADCC 
activity of lintuzumab, a humanized CD33-specific antibody which has been in clinical 
development for AML (R11-1471). 
 
 
 
The CD33 antigen is known to internalize upon antibody binding (R11-4256).
 
 
 
 
 
 
 
 
Preliminary data from this first-in-human dose escalation study with BI 836858 (trial number 
1315.1) in patients with relapsed or refractory acute myeloid leukemia investigating a weekly 
dose (q1w) is available.  As of the data cut-off date 12 April 2016, 26 patients were treated 
with BI 836858, all with doses of 10, 20 and 40 mg, respectively. The most frequent drug-
related AE Preferred Term (PT) was infusion-related reaction (IRR) in eleven out of 26 
patients (42 %). Adverse events considered a sign or symptom of an IRR by the investigator 
included back pain, chest pain, chills, dyspnea, fever and hypotension. All patients recovered 
from their IRRs with adequate symptom-oriented therapy. Drug-related transient increase of 
liver function tests was reported in four patients: one patient with grade 1 aspartate amino

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
New therapeutic strategies are needed to significantly improve the prognosis of AML patients 
with relapsed/refractory disease, but also for AML patients in CR with a high risk to relapse. 
Recent successful developments of signal transduction inhibitors or antibodies targeting
specific molecules that are deemed important for the malignant cell biology have spurred the 
search for other targets and respective antibodies.
CD33 is a valid target to treat patients with AML, as CD33 is expressed on the majority of 
AML cells (R11-1472) and on leukemic stem cells, but not outside of the hematopoietic 
system (R11-1473). 
CD 33 targeting approaches have been evaluated in clinical trials in AML patients. 
Gemtuzumab Ozogamicin (Mylotarg®), an immunoconjugate of a CD 33 mAb and 
calicheamicin, was approved by the Food and Drug Administration (FDA) in 2000 for 
patients over the age of 60 with relapsed AML, or those who are not considered candidates 
for standard chemotherapy. In June 2010 Mylotarg® was withdrawn by FDA request, due to a 
negative benefit risk assessment in a Phase III trial. As Mylotarg is an immunconjugate of a 
CD 33 mAb and a toxin, the MoA and also the safety profile are different to BI 836858. 
Clinical data of relapsed/refractory AML patients who were treated with the humanized 
CD33 IgG1 monoclonal antibody (mAb) lintuzumab are published (R11-1474, R01-1267, 
R11-1481). In these trials, administration of lintuzumab was safe and has shown signs of 
clinical efficacy (ORR) of 17 % in a Phase I trial in relapsed / refractory AML (R11-1481).  
Lintuzumab was also explored in a Phase I study in patients with APL after remission 
induction. Multiple doses of lintuzumab could be administered safely and appeared to 
eliminate minimal residual disease detectable by RTPCR in some patients. (R11-4695)
The clinical experience with lintuzumab supports the assumption that targeting CD33 with an 
IgG1-type antibody may translate into clinical benefit in patients with AML with an 
acceptable side effect profile. 
 
BI 836858 is a monoclonal antibody which mechanistically relies on effector-cell mediated
immune mechanisms, in particular ADCC (antibody dependent cellular cytotoxicity) and
ADCP (antibody dependent cellular phagocytosis). ADCC predominantly depends on the
presence of natural killer (NK) cells and ADCP on the presence of myeloid derived effector
cells (i.e. monocytes and macrophages). In a recent publication, where NK cell phenotype 
and function was assessed in 32 consecutive AML patients including 12 achieving complete 
remission, it was reported that NK cells in relapsed and refractory AML patients have 
impaired functionality. It was also shown that phenotypic and functional abnormalities of NK 
cells are partially restored in AML patients achieving a CR. (R15-6192).

It is likely that BI 836858 requires the presence of functional NK cells and monocytes to 
achieve clinical benefit in AML patients. AML patients who have achieved a CR have an 
improved effector cell profile (NK cells and monocytes) and may have a higher likelihood to 
benefit from the pharmacological activity of BI 836858.
 
 
 
 
 
 
This trial was the first administration of BI 836858 in humans.
2.2
TRIAL OBJECTIVES
The primary objective of this trial is to determine the maximum tolerated doses (MTDs) of 
BI 836858.  BI 836858 is a new biological entity (NBE) and the MTD may not be reached. 
To learn more about the safety and preliminary efficacy there will be an expansion cohort 
either at the MTD or the highest tested dose (e.g. 320 mg). Secondary objectives are to 
document the safety and tolerability of BI 836858, 
 
and to evaluate efficacy (see Section 5).
2.3
BENEFIT - RISK ASSESSMENT
Although considerable progress has been achieved in understanding the etiology and biologic 
behavior of AML and the development of more effective treatment regimens are ongoing,

most patients with refractory or relapsed AML have a very poor prognosis. Re-induction 
followed by allogeneic stem cell transplantation is the most common regimen for refractory 
or relapsed AML patients, however many are not eligible for such an intensive treatment. For 
those patients with refractory or relapsed AML ineligible for intensive treatment, or for those 
with refractory or relapsed disease after allogeneic stem cell transplantation, no approved or 
standard treatment is available. 
AML patients in CR who have been initially diagnosed with non-favorable genetics and 
either have received induction and consolidation treatment and are not candidates for 
allogeneic hematopoietic stem cell transplantation (e.g. no donor available, not eligible/fit 
enough) or have received an allogeneic hematopoietic stem cell transplantation have a very 
high risk to relapse. For those patients no standard therapy to maintain the CR is currently 
available. 
BI 836858 is a monoclonal antibody, which specifically targets CD33. Targeting CD33 in 
patients with AML may potentially offer a benefit to those patients since CD33 is expressed 
on AML blasts in the majority of AML patients (see Section 1.2). In vitro, BI 836858 is a 
potent inducer of ADCC, which results in cytolysis of AML-derived cell lines and primary 
AML blasts from peripheral blood and bone marrow. In the clinical setting, these effects may 
potentially result in anti-leukemic activity as a monotherapy, but also offer potential for 
combination with other drugs in patients with AML.
CD33 is not known to be expressed outside of the hematopoietic system. The anticipated side 
effect profile of BI 836858 based on the CD33 expression profile comprises predominantly 
hematologic adverse events such as neutropenia. These hematological adverse events are 
frequently reported in patients with hematological diseases and may be due to the underlying 
disease, the treatment or both. The preclinical safety assessments for BI 836858 have 
revealed TNF-alpha and INF-gamma release, suggesting a potential for infusion reactions. 
Clinical data from 26 patients are available from this first in human study 1315.1. 
 
 
Infusion reactions were the most frequently observed drug related adverse event in this first 
in human study and is newly classified as a listed (expected) adverse event. Infusion-related 
reactions are frequently observed with monoclonal antibodies in hematological indications, 
and signs/symptoms of IRRs reported for BI 836858 are in line with AEs reported for other 
antibodies approved in hematology indications. To mitigate the risk for IRRs, protocol 
specified precautions must be adhered to, i.e. premedication, rate-controlled infusion 
schedule and symptom monitoring. If an IRR occurs the infusion of BI 836858 should be 
paused and additional supportive measures are recommended based on standard of care, e.g. 
additional corticosteroid or non-steroidal analgesics and/or opioids.in. So far no case of life-
threatening IRR was reported; however in case a patient is developing a life-threatening IRR 
despite appropriate premedication the patient should discontinue the treatment with BI 
836858 permanently. Drug-related transient increase of LFT was reported in 4 patients. In 
none of these cases Hy´s law criteria were met. Frequent testing of LFTs is mandated during 
treatment with BI 836858 (frequency defined in the clinical trial protocols). In case of

Patients with refractory or relapsed AML with limited or no standard treatment options may 
benefit from blast cell reduction and disease stabilization following treatment with 
BI 836858. AML patients in CR who have been initially diagnosed with non-favorable 
genetics with a very high risk to relapse with limited or no standard treatment options may 
benefit from targeting CD33 positive leukemic stem cells and maintenance of achieved 
complete remission to initial standard therapy.
The potential benefit of therapy with BI 836858 is expected to outweigh the treatment-related 
risks.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This trial will be performed in two separate patient populations: 1) Patients diagnosed with 
relapsed or refractory AML who have failed at least one prior line of therapy and 2) patients 
with AML who are in complete remission (CR) with a high risk to relapse. It will be 
performed in an open, non-randomized, 3+3 design followed by an expansion cohort. A cycle 
will comprise of 14 days. 
For patients with refractory or relapsed AML, one cycle is 14 days with two administrations 
of BI 836858 (i.e. administrations on Days 1 and 8).  Patients with clinical benefit, defined by 
the International Working Group (IWG) as having objective response (partial remission (PR) 
or complete remission (CR) or complete remission with incomplete blood recovery (CRi)) or 
subjective response (in the absence of objective response) after 8 administrations and who are 
tolerating the infusions, may continue until progressive disease (PD) and as long as neither 
patient nor Investigator requests treatment discontinuation.
For AML patients in CR, one cycle is 14 days with one administration of BI 836858 (i.e. 
administrations on Days 1) in Cycles 1, 2 and 3.  From the 4th cycle onwards, patients will 
receive monthly (every second cycle) infusions of BI 836858 (i.e. 4th infusion on Cycle 5 Day 
1, 5th infusion on Cycle 7 Day 1) for overall up to one year of treatment unless these patients 
relapse or infusions are not tolerated.  
To determine separate MTDs for each patient population, cohort dose escalation will be 
conducted following the 3+3 design for the refractory or relapsed AML patients and the 
patients with AML in CR with high risk to relapse, respectively.  The dose level will be 
escalated with each new cohort until at least one out of three patients of a cohort experiences 
a dose limiting toxicity (DLT; for definition see Section 5.2.1.1) during the first two cycles
(DLT evaluation period).  If exactly one out of the three patients of the cohort experiences a 
DLT, three additional patients will be treated at the same dose level.  If none of the three 
additional patients experiences a DLT, then the cohort dose escalation will be continued by 
treating the next three patients at the next higher dose level.  If at least two out of up to six 
patients at a dose level experience a DLT, the MTD has been exceeded and the dose will be 
deescalated until a dose level is reached in which at most one DLT out of six patients is 
observed (R01-0028).  The MTD is defined as the dose of BI 836858 that is one dose cohort 
below the dose at which two or more out of six patients experienced DLT.  At the maximum 
tolerated dose, no more than one patient out of six patients may experience DLT, i.e., the 
MTD is defined as the highest dose studied for which the incidence of dose-limiting toxicity 
is no more than 17% (i.e. 1/6 patients) during the first two cycles.
Patients are considered to have completed the first two cycles if they have reached end of 
cycle 2 and have received all planned administrations of BI 836858 (i.e. 4 administrations for 
patients with relapsed or refractory AML and 2 administrations for patients in CR).

However, for those patients who receive more than two cycles of BI 836858, all DLT 
occurring after end of cycle 2 will be taken into consideration for further development of BI 
836858.

next lower dose level.
During the dose escalation phase, each patient will receive up to 2 repeated treatment cycles
before DLT assessment. 
For both patient populations the dose is planned to be escalated in cohorts at pre-defined dose 
levels based on a multiplication factor of 2. The dose levels are 10 mg, 20 mg, 40 mg, 80 mg, 
160 mg, and 320 mg as outlined in Section 4.1.3. However, for AML patients in CR, the dose 
escalation will start with the 40 mg dose cohort and follow the same dose escalation levels.
Intermediate dose levels and dose levels higher than 320 mg may be investigated if agreed 
upon between Investigator and Sponsor.  
After definition of the MTD, it is planned to enroll an expansion cohort of 12 patients to 
better characterize the safety of BI 836858. In case no MTD is reached up to the highest 
planned dose (e.g., 320 mg), 12 additional patients will be treated with each respective 
schedule at the highest test dose (i.e., 320 mg) of BI 836858. 
The primary analysis will take place when all patients from the cohort dose escalation and 
dose expansion cohorts have had a minimum of 4 cycles or have discontinued from the trial 
prior to reaching end of cycle 4 due to meeting the criteria for withdrawal as outlined in 
Section 3.3.4.1.
3.1.1
Administrative structure of the trial

In regular telephone conferences between the participating Investigators and the Sponsor, 
there will be discussions of safety assessments, recommendations for cohort dose escalation, 
to reach a consensus on DLT, and whether to continue or modify the trial.  
All safety laboratory analyses will be performed locally at each clinic site in the schedule 
outlined in the Flow Charts. All of the biomarker analyses will be performed at 
 
 with the exception of cytokine analyses which will be performed in locations 
noted in Section 5.6.3.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
The primary objective of this trial is to determine the MTD for both patient populations 
separately. The most important secondary objective is to assess the safety of BI 836858.  This 
can be achieved by an open label, single arm design without a control group.
Adult patients with refractory/relapsed AML are considered eligible for this trial.  
Relapsed AML is defined as recurrent disease after prior remission of any duration. 
Refractory disease is defined as failure to achieve remission to most recently administered 
therapy. Patients with primary refractory disease, defined as failure to achieve remission to 
initial therapy, are eligible. Typically patients with primary refractory disease are defined as 
refractory after failure of two cycles of intensive induction. Patients with failure of a single 
cycle of induction are eligible for this trial if they refuse to receive a second induction cycle 
or if they are not candidates for a second intensive induction cycle. Patients receiving 
hypomethylating agents as initial induction should receive at least two cycles of induction 
before designation as refractory.
AML patients in CR who have been initially diagnosed with non-favorable genetics have a 
very high risk to relapse. Eligible patients for this trial should either have received induction 
and consolidation treatment and are not candidates for allogeneic hematopoietic stem cell 
transplantation (e.g. no donor available, not eligible/fit enough) or have received allogeneic
hematopoietic stem cell transplantation. For those patients no standard therapy to maintain 
the CR is currently available.
These AML patient groups were selected for inclusion in this trial, because these patients 
constitute groups with unfavourable prognosis for whom currently no satisfactory standard 
treatment exists.
The trial design will follow a 3+3 design with cohort dose escalation and de-escalation for 
both patient groups. Once the MTD has been defined, an expansion cohort of 12 patients is 
planned to be enrolled to better characterize the safety profile and tolerability of the MTD. In 
case no MTD is reached up to the highest planned dose (e.g., 320 mg), 12 additional patients 
will be treated with the respective schedule of the highest tested dose (e.g., 320 mg) of         
BI 836858.  This trial design is accepted for hematology Phase I studies.

For patients with refractory or relapsed AML, the first efficacy assessment via bone marrow 
aspirate will be performed after 2 cycles (4 administrations).  Subsequent disease assessment 
will be performed after 4 cycles (8 administrations) and at the discretion of the Investigator.  
For AML patients in CR, disease status will be followed up on a regular basis with peripheral 
blood count and a bone marrow assessment will be performed if suspicion of relapse. Patients 
with a MRD marker will be followed up on this marker as well, however this is explorative.  
Intra-patient dose escalation will be allowed for selected patients in case the next higher dose 
cohort is free of DLT and considered safe. This is not considered a safety risk because it will 
be restricted to patients who have tolerated at least three cycles of BI 836858 at the time of 
dose escalation and may offer a potential benefit to patients enrolled at a lower dose.
Each patient will be closely monitored for infusion-related reactions, as this is a potential 
side-effect for mAbs.
Safety assessments will be performed at all visits during the treatment phase.
The trial shall allow the investigation of BI 836858 in AML with regard to safety and the 
definition of the optimal dose for the future clinical development program in this disease.
3.3
SELECTION OF TRIAL POPULATION
Approximately 50 patients with relapsed or refractory AML and about 35 AML patients in 
CR with high risk to relapse will be screened. Of these patients, approximately 36 with 
refractory or relapsed AML and approximately 27 patients with AML in CR with high risk to 
relapse will be included in this trial from a target of 5 sites. Each site will screen a target of 
about 10 patients.
A log of all patients included into the study (i.e. having given informed consent) will be 
maintained in the investigator site file (ISF) at the investigational site irrespective of whether 
they have been treated with investigational drug or not.
3.3.1
Main diagnosis for study entry
Patients with relapsed or refractory AML as defined according to the World Health 
Organization (WHO) criteria will be eligible for this trial (see Section 3.2),
AND
Patients with AML in CR with high risk to relapse will be eligible for this trial (see also 
Section 3.2). AML in CR with high risk to relapse is defined as follows:
a) AML patients with non-favorable genetics (according to European LeukemiaNet 
(ELN) classification) that are in CR after having received induction and consolidation 
chemotherapy and are not candidates for allogeneic hematopoietic stem cell 
transplantation (SCT) (e.g., no donor available, not eligible/fit enough)

3.3.4
Removal of patients from therapy or assessments
3.3.4.1
Removal of individual patients
An individual patient is to be withdrawn from the trial if:

The patient withdraws consent. Patients are free to discontinue their participation in 
this trial at any time without the need to justify the decision.

The patient needs to take concomitant drugs which may interfere with the 
investigational product (please refer to Section 4.2.2).

The patient is no longer able to participate for other medical reasons (e.g. adverse 
events unrelated to therapy or disease progression, concomitant diagnoses, pregnancy, 
surgery or administrative reasons). The Investigator may also stop a patient's 
participation if the patient is no longer able to attend trial visits.
A patient can be withdrawn from the trial after discussion between the Investigator and the 
Sponsor if eligibility criteria are violated and/or the patient fails to comply with the protocol.
All withdrawals will be documented and the reason for withdrawal recorded and discussed, as 
necessary, in the final report of the trial. As soon as a refractory or relapsed AML patient is 
withdrawn from the trial treatment, the end of active treatment (EOT) visit has to be 
performed if feasible. For patients with AML in CR, as soon as a patient is withdrawn from 
the trial treatment, the end of active treatment (EOT) visit and the End of Residual Effect 
Period (REP) visit (EoR visit) must be performed if feasible.  Every effort should be made to
follow-up with patients in case an adverse event (AE) is still ongoing at the time of 
withdrawal.  If a patient is withdrawn from the trial due to consent withdrawal, no further 
visits will be completed and no further trial data will be collected. However, if information 
about survival status is available in the public domain, then the Investigator is requested to 
report this information in the eCRF.
A patient has to discontinue trial drug administration in case:

A DLT occurs which does not recover to a degree that allows treatment continuation 
(see Section 4.1.4).

Progressive disease (PD) or any other concomitant diagnosis/symptom develops 
resulting in an indication to start any other therapy for AML, including deterioration 
of general condition.
Patients not completing the first two cycles (with all planned BI 836858 administrations) for 
reasons other than DLT will be replaced.
3.3.4.2
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for the following reasons:

TREATMENTS
4.1
TREATMENTS TO BE ADMINISTERED
BI 836858 will be administered as rate-controlled intravenous infusion. In case a patient 
experiences an adverse event during the infusion, the duration of the infusion may be 
expanded until the use-by date and use-by time indicated on the label is reached.  The actual 
duration of the infusion needs to be documented in the electronic case report form (eCRF)
including actual start and end time, actual time points for interruption and restart of the 
infusion and the actual infusion rates.
Adverse events during the infusion will be thoroughly documented and characterized to allow 
differentiation between infusion-related reactions (R10-4428, R10-4517).
4.1.1
Identity of BI investigational product and comparator product
The characteristics of the test product are below.

Substance (INN):
BI 836858

Pharmaceutical form:  
Solution for infusion after dilution

Source:
Boehringer Ingelheim Pharma GmbH & Co. KG

Unit strength: 
10 mg/mL (vials with 10mL)

Daily dose:
See Section 4.1.3

Duration of use:
Single administration every 7, 15, or 29 days
(depending on patient population)

Route of administration:
Intravenous

Posology:
Rate controlled infusion
(Volume:  250 mL)
The first and second infusion will be started at a rate of 10 mL/h. The infusion rate should be 
increased every 30 (+/-10) minutes by 10 mL/h to a maximum of 80 mL/h as long as 
tolerated by the patient. Infusion should not exceed 8 hours. If considered safe by the 
Investigator, the stepwise increase of infusion rate during the third and subsequent infusions 
may be faster or steps may be omitted, but the maximum infusion rate must not exceed 120 
mL/h. If symptoms of an infusion-related reaction occur, the infusion should be temporarily 
stopped. Upon recovery, it should be infused at 50% of the rate at which the reaction 
occurred and should not be dose escalated from this dose for at least 30 minutes. Lower rates 
may be selected if clinically indicated. Depending on the time of occurrence and the severity 
of the reaction, the investigator may consider administering additional supportive medication, 
e.g. corticosteroids. A stepwise re-increase of the infusion rate to a maximum of 80 mL/h is 
possible. For medical reasons, in case a patient experiences an adverse event during the 
infusion, the duration of the infusion may be expanded until the use-by date and use-by time 
indicated on the label is reached. The actual duration of the infusions and infusion steps need 
to be documented in the eCRF including actual start and end time, actual time points for 
interruption and restart of the infusion and the actual infusion rates.

Method of assigning patients to treatment groups
Not applicable.  This is a single-arm, open-label, cohort dose escalation trial.
4.1.3
Selection of doses in the trial
BI 836858 will be administered as a rate-controlled intravenous infusion every 7 days to
refractory or relapsed AML patients.  
For AML patients in CR, the first three administrations will be given every second week, on 
day 1 of Cycles 1, 2 and 3.  From the 4th administration onwards, patients will receive 
monthly (every second cycle) infusions of BI 836858 (i.e. 4th infusion on Cycle 5 Day 1, 5th
infusion on Cycle 7 Day 1…) for overall up to 12 months of treatment unless these patients 
relapse or infusions are not tolerated.
Patients with refractory or relapsed AML have a high medical need and a bad prognosis. To 
treat this patient population with a sub saturating dose is not warranted and therefore a 
starting dose close to the full saturation of all CD33 sites is chosen. The starting fixed dose of 
10 mg which is a dose level expected to provide near to the full saturation of all CD33 sites at 
maximum measured plasma concentration (Cmax) based on estimated receptor occupancy (i.e. 
94.3% estimated CD33 occupancy). For lintuzumab, a CD33 monoclonal antibody, in a 
Phase I trial no MTD was reached up to 8mg/kg/week (R11-1481). A fixed dose regimen was 
chosen instead of a dose per m2 based a recent publication by Wang et al. The individual and 
population performance of body size-based and fixed dosing in adults were compared for 12 
oncology approved mAbs (R10-6267).  Although both dose regimens demonstrated similar 
performance, the fixed dose was recommended since it offered advantages in the ease of dose 
preparation and a lower chance of dosing errors.
For details please refer to the Investigator’s Brochure, Section 5.3.6 (c02324887-03).
The dose is planned to be escalated in cohorts at pre-defined dose levels based on a 
multiplication factor of 2. The dose levels are 10 mg, 20 mg, 40 mg, 80 mg, 160 mg, and 320 
mg. Intermediate dose levels and dose levels higher than 320 mg may be investigated if 
agreed upon between Investigator and Sponsor.  In an ongoing Phase I study BI 836858 is 
administered to lower risk MDS patients every 14 days. In the 20 and 40 mg cohort no DLT 
occurred and the 80mg cohort is currently ongoing. The dose escalation in AML patients in 
CR will begin with infusions at the dose level of 40 mg.  The dose will be escalated to the 
next pre-defined or intermediate dose levels as needed. 
When a cohort dose escalation is to be performed, the data of all previous dose cohorts will 
be reviewed and discussed between the participating Investigators and the Sponsor. This 
assessment will determine if each patient population is able to continue treatment with         
BI 836858.
During the cohort dose escalation phase, enrolment into the first dose cohort (10 mg) will be 
allowed at the earliest 7 days after the first administration of  BI 836858 between patient 1

and 2 and subsequently between patient 2 and 3.  In case the 10 mg cohort has to be expanded 
to 6 patients, a one week observation period must be followed between the first 
administration of BI 836858 and the start of the subsequent patient. For subsequent cohorts 
(i.e., 20 mg, 40 mg, 80 mg, 160 mg, and 320 mg), consecutive screening is allowed; however, 
there has to be an interval of at least 3 days between the 1st administration of BI 836858 for
each patient. 
Enrolment into the next higher dose cohort is allowed after the previous dose cohort was 
found to be safe for the initial administration for all patients in this cohort (e.g. at least 28 
days after the first administration of drug in the last patient entered into the cohort).
Once the MTD for one of the patient populations is defined, a dose for treatment of the 
expansion cohort in this patient population will be determined, which will not exceed the 
MTD.  In case no MTD is reached up to the highest tested dose (e.g. 320 mg), 12 additional 
patients will be treated with the respective schedule of the highest tested dose (e.g. 320 mg)
of BI 836858 in the expansion cohort. During treatment of the expansion cohort, new patients 
may be enrolled at any time.

4.1.4
Drug assignment and administration of doses for each patient
Prior to inclusion of a new patient during the cohort dose escalation phase, the Investigator
has to confirm the actual dose tier of BI 836858 for the patient with the Sponsor who 
oversees the cohort dose escalation steps and the safety data of patients from all trial sites.  
BI 836858 will be administered as an intravenous infusion under the supervision of the 
Investigator or designated personnel.
BI 836858 may be administered at any time during the day.  However, to 
 
 it is recommended to 
start the infusion during the morning hours.

For refractory or relapsed AML patients:  BI 836858 will be administered as weekly i.v. 
infusions in 14-day cycles (i.e., Days 1 and 8; 2 infusions per cycle).
For AML patients in CR: the first three administrations will be given once every second week 
on day one of 14-day Cycles 1, 2 and 3 (i.e., Days 1, 15 and 29).  From the 4th administration 
onwards, patients will receive monthly (every second cycle) infusions of BI 836858 (i.e. 4th
administration on Cycle 5 Day 1, 5th administration on Cycle 7 Day 1 …) for overall up to 12 
months of treatment.
Premedication
Premedication to prevent infusion-related reactions is obligatory 30 minutes (up to 120 min 
before start of administration of BI 836858 is permissible) prior to the first three
administrations of BI 836858, unless a contraindication for premedication exists, and should 
include:

Acetaminophen/Paracetamol 650 mg - 1000 mg p.o., or equivalent

Antihistamine p.o. or i.v., equivalent to Diphenhydramine 50 mg i.v.

Glucocorticoid i.v., equivalent to prednisolone 100 mg
For patients with refractory or relapsed AML: 
If BI 836858 has been well tolerated without signs of infusion-related reactions in the first 
administration, glucocorticoid premedication may be reduced to a dose equivalent to 50 mg 
prednisolone for the second through fourth administrations, and in case this is well tolerated 
reduce the steroids with the 5th infusion (25 mg with the 5th and 0 mg with the 6th infusion.)
For AML patients in CR:
If BI 836858 has been well tolerated without signs of infusion-related reactions in the first 
administration, glucocorticoid premedication may be reduced to a dose equivalent to 50 mg 
prednisolone for the second administration, and in case this is well tolerated steroids can be 
omitted with the 3rd infusion. 
For both patient populations, however, in case an administration of BI 836858 was not well 
tolerated, the premedication with prednisolone can be re-escalated up to 100 mg.
Retreatment                                                                                                                         
Before the next administration of BI 836858, adverse events and safety laboratory will be 
assessed.  To continue treatment with further administrations, all of the following criteria 
must be met:
Refractory or relapsed AML patients
(1)
Neutrophils ≥500 /μL (0.5 x 109/L) and platelets ≥25,000 /μL (25 x 109/L), unless 
CTCAE Grade 4 neutropenia or thrombocytopenia was preexistent prior to trial 
entry. Patients with active leukemia who go from Grade 3 neutropenia to Grade 4 
neutropenia after treatment may continue on study provided there is no evidence 
of infection or febrile neutropenia. Patients with active leukemia who go from

Grade 3 to Grade 4 thrombocytopenia after treatment may continue on study 
provided that post-transfusion platelet count is at least 20,000/µL before therapy is 
given.
(2)
Acceptable tolerability (in case of an AE at the planned start of a further 
administration, patients may continue therapy only after recovery to a level which 
would allow further therapy, i.e. CTCAE grade 1 or pre-treatment value); no 
febrile neutropenia (≥38.5°C and ANC <1000/µL) and no uncontrolled infection. 
Patients who do not meet these criteria for further therapy should be discussed 
with the TCM and/or the Coordinating Investigator and may be eligible to 
continue if the toxicity is not clinically significant.
AML patients in CR
(1)
Neutrophils ≥750 /μL (0.75 x 109/L) and platelets ≥50,000 /μL (50 x 109/L). 
(2)
Acceptable tolerability (in case of an AE at the planned start of a further 
administration, patients may continue therapy only after recovery to a level which 
would allow further therapy, i.e. CTCAE grade 1 or baseline value.)
(3)
Patients with GvHD, with a CTCAE grade 1 or 2 and taking steroids, may 
continue further administration.  GvHD patients with a steroid-refractory (≥2 
mg/Kg) CTCAE grade 3 or higher, independent of receiving steroids, should be 
discontinued from study.
In case criteria 1 and 2 are not fulfilled, blood counts and/or the adverse event should be 
re-evaluated for up to three weeks.  In case of a treatment delay, the Sponsor must be 
notified. If criterion 1 is not fulfilled and the patient has <5% blasts in the bone marrow, 
absence of myelodysplastic changes, and/or absence of evidence of disease by flow 
cytometry in the bone marrow then no further treatment should be administered until 
discussion with the Sponsor.
Administration of the trial drug has to be stopped temporarily in case of a DLT (see 
Section 5.2.1.1).  Patients may continue therapy only after recovery from the DLT to a 
CTCAE level which allows further therapy based on Investigator assessment and only with a 
reduced dose of BI 836858.  The new dose of BI 836858 must be finally agreed on between 
the Sponsor and the Investigator.  The reduced dose will be valid for all following treatment 
cycles in the individual patient.  A reduction of the dose will be allowed only once for an 
individual patient during the whole trial.  In case a patient experiences a second episode of 
DLT with the reduced BI 836858 dose, the treatment has to be permanently discontinued.  
Likewise, treatment has to be discontinued in case the DLT is not reversible.
Intra-patient dose escalation
Intra-patient dose escalation may be considered in agreement between investigator and 
sponsor for selected patients. It is restricted to patients who have received at least 3 treatment 
cycles and tolerate the treatment well at the time of dose escalation. Intra-patient dose 
escalation can only be performed at a time when the next higher dose cohort has been

reviewed and considered safe by the sponsor and investigators. The dose escalation step is 
limited to the dose which has been administered to the next higher cohort. In addition, after 
the first dose at the higher dose level, patients have to be monitored for at least 24 hours after 
the end of the infusion, including safety laboratory 24 hours after the first administration of 
the escalated dose of BI 836858.

Blinding and procedures for unblinding
4.1.5.1
Blinding
This Phase I trial will be performed according to an open label, single arm design.  It will 
recruit two separate patient populations: 1) Patients with relapsed and refractory AML and 
active disease; and 2) AML patients in CR with high risk to relapse.  This trial will be 
handled in an open fashion by the Sponsor throughout, i.e. also for the purpose of data 
cleaning and preparation of the analysis.  The eCRF will contain information on the treatment 
and the dose.
4.1.5.2
Procedures for emergency unblinding
Not applicable.


availability of the Form 1572.
These records will include dates, quantities, batch/serial numbers, expiry (‘use by’) dates, and 
the unique code numbers assigned to the investigational product(s) and trial patients.  The 
Investigator and/or pharmacist must maintain records of the product’s delivery to the trial 
site, the inventory at the site, the use for each patient, and the return to the Sponsor or 
alternative disposition of unused product.  The Investigator/pharmacist will maintain records 
that document adequately that the patients were provided these doses specified by the CTP 
and reconcile all investigational product received from the Sponsor. At the time of return to 
the sponsor, the investigator must verify that all unused or partially used drug supplies have 
been returned by the clinical trial patient and that no remaining supplies are in the

All concomitant non-anti-leukemia therapies to provide adequate care may be given as 
clinically necessary.  All concomitant treatments will be recorded in the eCRF except for 
vitamins and 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 be specified in detail.  It should be indicated as ‘parenteral nutrition’.  If 
a patient needs anesthesia, it will be sufficient to indicate ‘anesthesia’ without specifying the 
details.
Concomitant therapy will be recorded in the eCRF during the screening and treatment period, 
starting at the date of signature of informed consent, and ending at the EOT-visit.  After the 
EOT-visit, only concomitant therapy indicated for treatment of an adverse event needs to be 
reported.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment
Prior anti-leukemia therapy must have been discontinued at least two weeks before the first 
administration of the trial drug (Hydroxyurea may be given during study participation) and 
the patient must have recovered from all clinically relevant reversible toxicities as determined 
by the investigator.  A time interval of at least 2 weeks (four weeks for biologics) must have 
elapsed from the last administration of any other investigational treatment for AML to the 
first administration of BI 836858.
For peripheral blood blast control, as this may correlate with the risk of occurrence of 
infusion related symptoms, hydroxyurea will be allowed (maximum dose of hydroxyurea 
3gm daily) before and during study participation. Blasts must be ≤ 5,000/µl at start of each 
administration of BI 836858. 
No other anti-neoplastic therapy concomitantly is allowed.
Short term glucocorticoid medications may be used up to 20 mg per/day continuously are  
allowed (see exclusion criterion 4) and up to 2 mg/kg bodyweight for short term. All other 
indications for steroids have to be discussed and agreed upon between Investigator and 
Sponsor.
Intrathecal treatment to control symptoms associated with central nervous system (CNS) 
involvement is allowed but must be discussed and agreed upon between Investigator and 
Sponsor.  All concomitant therapy will be recorded in the eCRF.

5.1.2.3
Assessment and definition of best overall response
For patients with refractory or relapsed AML, response will be assessed according to the 
criteria from the IWG based on laboratory data from the peripheral blood, bone marrow 
examination, clinical examination (at the end of each cycle), at the evaluation for further 
treatment-visit and the EOT-visit. Bone marrow examination will be performed before the 
Cycle 3 and Cycle 5 (5th and 9th administration of BI 836858) (i.e., BM performed on Day 1 
(+/-1) of cycles 3 and 5 and treatment started on Day 1 (up to +3) of cycles 3 and 5) and at 
the discretion of the Investigator, e.g. in case clinical and laboratory examinations of 
peripheral blood demonstrate that a CR has been achieved, or for assessment of persistent 
neutropenia, anemia or thrombocytopenia. 
For AML patients in CR, response will be assessed clinically and in the peripheral blood (on 
Day 1 of each cycle). In the case of suspected relapse based on peripheral blood counts a 
bone marrow examination will be performed. 
Assessment and definition of best overall response
Response will be evaluated according to the following criteria (modified from the IWG
criteria, R06-0452):

Complete remission (CR)
Morphologically leukemia free state (i.e. bone marrow with <5% blasts by 
morphologic criteria and no blasts with Auer rods, no evidence of extramedullary 
leukemia) and absolute neutrophil count ≥1000 /μL and platelets ≥100,000 /μL.  
Patient must be independent of transfusions (no transfusion for 1 week prior to the 
assessment).

Complete remission with incomplete blood count recovery (CRi)
All of the above criteria for CR must be met, except that absolute neutrophils 
<1000 /μL or platelets <100,000 /μL in the blood.  

Partial remission (PR)
All of the criteria for CR must be met, except that leukemic blasts in the bone marrow 
may range from 5 to 25% as long as the count has decreased by at least 50% from 
pre-study treatment, or <5% blasts in the presence of Auer rods or abnormal 
morphology.

Stable disease (SD)
Patient alive with no CR, CRi, PR or PD.


Treatment failure (TF)
Patient survives >7 days following completion of initial 2 treatment cycles (e.g. 
28 days) with persistent leukemia in the last peripheral blood smear or bone marrow 
(>25% blasts), or with persistent extramedullary disease, but without further clinical 
deterioration due to leukemia or increase of blast population in the bone marrow or 
peripheral blood.
Resistant disease: Patient survives >7 days post-course of treatment; persistent 
leukemia in blood or bone marrow.
Aplasia: Patient survives >7 days post-course of treatment; death while cytopenic, 
with aplastic bone marrow
Indeterminate cause: Patients who die < 7 days post therapy. Patients who die > 7 
days post therapy with no peripheral blood blasts, but no bone marrow examination.
Patients who do not complete the first course of therapy.
Morphologic relapse (recurrence): Reappearance of blasts post-CR or CRi in 
peripheral blood or bone marrow. That is, bone marrow leukemic blasts ≥ 5% or 
reappearance of blasts in the blood not attributable to any other cause (e.g. bone 
marrow regeneration), or development of extramedullary disease.

Progressive disease (PD)
Patient survives >7 days following completion of initial 2 treatment cycles (e.g. 
28 days) with increase of blast population in the bone marrow or peripheral blood by 
>50% or aggravation or new development of extramedullary disease or further 
deterioration or death due to leukemia.  Patients with a global deterioration of health 
status requiring discontinuation of treatment without objective evidence of PD at that 
time should be classified as having ‘clinically progressive disease’.  Every effort 
should be made to document the objective PD even after discontinuation of treatment.
Definition of best overall response
Best overall response is defined as the best overall response (CR, CRi, PR, TF, PD or not 
evaluable in this order) recorded since first administration of BI 836858.
5.1.2.4
Progression free survival (PFS)

PFS is defined as the time from first treatment with BI 836858 until disease 
progression, relapse or death.

The date of progression/relapse will be the earliest of the dates of the disease 
assessment (blood sample, bone marrow sample, or clinical assessment) in which the

Time to treatment failure (TTF)
Some patients will receive the next line of therapy, although no formal PD may be diagnosed 
at the time when the next treatment is indicated according to Investigator assessment.  In 
addition to PFS, the TTF will be calculated.

TTF is defined as the time from first treatment with BI 836858 until objective disease 
progression, relapse or death or start of next AML therapy.

The date of progression/relapse will be the earliest of the dates of the disease 
assessment (blood sample, bone marrow sample, or clinical assessment) in which the 
progression/relapse was observed. For patients who did not progress, relapse, die, or

SAFETY
5.2.1
Endpoints of safety
Primary endpoints:

Maximum tolerated dose (MTD)

Number of patients with Dose Limiting Toxicity (DLT) during the MTD evaluation 
period:
o
For patients with refractory or relapsed AML, the first two cycles (i.e. patient 
has received at least 4 administrations of BI 836858 and reached end of cycle 
2). 
o
For AML patients in CR with high risk to relapse, the first two cycles (i.e. 
patient has received at least 2 administrations of BI 836858 and reached end of 
cycle 2).
 
As this trial is the first in human use of BI 836858, the primary objective is to determine the 
MTD of BI 836858 and assess the safety of the drug in humans.  For details on determination 
of MTD, please refer to Section 3.1, Section 5.2.1.1 and Section 7.3.1.
The safety of BI 836858 will be assessed by a descriptive analysis of incidence and intensity 
of adverse events (AE) graded according to the CTCAE version 4.0, the incidence of DLT, 
laboratory data and results of physical examination.
The Sponsor will review the safety data with the participating Investigators at regular 
intervals and as ad hoc if needed.
The safety endpoints will be assessed in a descriptive way without confirmatory analyses.
5.2.1.1
Dose limiting toxicity (DLT) for refractory or relapsed AML patients
DLT is defined as any non-disease-related non-hematological AE of CTCAE grade 3 or 
higher. Expected non-hematological disease related AE´s such as complications resulting 
from haematological AEs include:

bleeding and complications from bleeding due to thrombocytopenia as defined by the 
investigator 

infection and complications from infections due to neutropenia as defined by the 
investigator


constitutional symptoms due to anemia as defined by the investigator 
Infusion-related reactions (IRRs, CTCAE grade 3 or higher) associated with the 
administration of BI 836858 should be reported as Adverse Event of Special Interest (AESI, 
refer to Section 5.2.2.1), but will not be regarded as a DLT.  The exception is anaphylaxis
which occurs despite premedication with glucocorticoid or which does not resolve with 
glucocorticoid (i.e. such cases of anaphylaxis will be regarded as a DLT).
Infection will not constitute a DLT unless it is felt that the infection resulted from 
unexpectedly complicated myelosuppression; degree of severity and/or duration as assessed 
by the Investigator. 
Hematological AEs, e.g. neutropenia, thrombocytopenia and anemia are frequently 
pre-existing in AML patients and are therefore AEs not considered as DLT. Failure to 
recover neutrophil count (ANC>500/uL) or platelet count (>25000/uL) at the first bone 
marrow evaluation after 2 cycles of BI 836858 in patients with < 5% blasts in the bone 
marrow, absence of myelodysplastic changes, and/or absence of evidence of disease by flow 
cytometry in the bone marrow will be considered a DLT. For patients with > 5% blasts, 
myelodysplastic changes, or evidence of disease by flow cytometry/cytogenetics, failure to 
recover neutrophil or platelet count may not be considered DLT as this could be the result of 
persistent disease. 
Patients who have not completed at least 4 administrations (2 cycles) of BI 836858 due to BI 
836858 related toxicity will be considered as a DLT.
5.2.1.2
Dose limiting toxicity (DLT) for AML patients in CR
DLT is defined as any non-disease-related AE of CTCAE grade 3 or higher. Patients in 
remission are not expected to have disease-related AEs.  In case of any hematological AE of 
CTCAE grade 3 or higher, relapse of AML has to be excluded. Infusion-related reactions 
(IRRs) associated with the administration of BI 836858 should be reported as Adverse Events 
of Special Interest (AESI, refer to Section 5.2.2.1), but will not be regarded as a DLT.  The 
exception is anaphylaxis which occurs despite premedication with glucocorticoid or which 
does not resolve with glucocorticoid (i.e. such cases of anaphylaxis will be regarded as a 
DLT).
Occurrence of and/or worsening of GvHD will not be considered as a DLT; however, these 
cases will be reviewed carefully during the safety assessment meetings.
AML patients in CR who have not completed at least 2 administrations (2 cycles) of BI 
836858 due to BI 836858 related toxicity will be considered as a DLT.
Once each patient of a cohort has completed 2 treatment cycles of BI 836858 all available 
safety data will be reviewed by the Sponsor, Coordinating Investigator and other participating 
Investigators who enrolled at least one patient. Safety data will be discussed via a

teleconference, initiated by Sponsor, to reach a consensus on DLT, in order to allow dose 
escalation, cohort expansion or suspension of further dose escalation.
All DLTs occurring at any time will be reported as an adverse event of special interest (AESI, 
see Sections 5.2.2.1 for definitions and 5.2.2.2 for reporting requirements).
5.2.2
Assessment of adverse events
5.2.2.1
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 medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable 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.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and 
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure. Conditions of use outside the marketing authorization include off-
label use, overdose, misuse, abuse and medication errors.
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:

results in death,

is life-threatening, this 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.

requires inpatient hospitalisation or 

prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, or

is a congenital anomaly / birth defect, or

is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Medical and scientific judgement should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be

immediately life threatening or result in death or hospitalisation but might jeopardise the 
patient or might require intervention to prevent one of the other outcomes listed above. 
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation or 
development of dependency or abuse. Any suspected transmission via a medicinal product of 
an infectious agent is also considered a serious adverse reaction.
AEs considered “Always Serious”
Every new occurrence of cancer of new histology must be reported as a serious event 
regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further 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 RDC system. 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 above.
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, please see above.
The following are considered as AESIs:

infusion-related reactions (CTCAE grade 3 or higher),

any event that qualifies for DLT, and

hepatic injury (DILI).
Hepatic injury
A hepatic injury (DILI) is defined by 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 draw sample, and/or

marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN

These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the “DILI checklist” provided in the ISF. 
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
Intensity of AEs
The intensity of adverse events should be classified and recorded in the CRF according to the 
Common Terminology Criteria for Adverse Events (CTCAE, version 4.0, R09-2850).
Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal relationship 
between a medicinal product and an occurrence is suspected. 
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. 
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:
•
The event is consistent with the known pharmacology of the drug 
•
The event is known to be caused by or attributed to the drug class.
•
A plausible time to onset of the event relative to the time of drug exposure.
•
Evidence that the event is reproducible when the drug is re-introduced
•
No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).
•
The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).
•
An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:
•
No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)
•
Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives).
Of note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.

•
Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).
•
Disappearance of the event even though the study drug treatment continues or remains 
unchanged.
5.2.2.2
Adverse event collection and reporting
AE Collection
The Investigator shall maintain and keep detailed records of all AEs in their patient files.
The following must be collected and documented on the appropriate CRF(s) by the 
Investigator:

From signing the informed consent onwards through the Residual Effect Period 
(REP), until individual patient’s end of trial: 
All AEs (serious and non-serious) and all AESIs. 

However, if an individual patient discontinues trial medication prematurely but stays 
in the trial (i.e. if further visits incl. telephone visits, or vital status assessments are 
planned) from then on and until the individual patient’s end of the trial the 
Investigator must report related SAEs and related AESIs. 

After the individual patient’s end of trial: 
The Investigator does not need to actively monitor the patient for AEs but should only 
report relevant SAEs and relevant AESIs of which the Investigator may become 
aware of.
The rules for Adverse Event Reporting exemptions (see below in paragraph “Exemptions to 
(S)AE Reporting”) still apply.

The REP is defined as 30 days after the last trial medication application. All AEs which 
occurred through the treatment phase and throughout the REP will be considered as “on 
treatment,” please see Section 7.3.3. Events which occurred after the REP will be considered 
as “post-treatment” events.
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). 
The same timeline applies if follow-up information becomes available. 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.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the Investigator should provide the information requested on the appropriate 
CRF pages and the BI SAE form. The Investigator should determine the causal relationship 
to the trial medication and any possible interactions between the investigational drug(s) and a 
Non-Investigational Medicinal Product (NIMP) / Auxiliary Medicinal Product (AMP).
The following should also be recorded as an (S)AE in the CRF and SAE form (if applicable):
Worsening of the underlying disease or of other pre-existing conditions 
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 individual patient’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.
Pregnancy
In rare cases pregnancy may occur in a clinical trial. Once a patient has been enrolled into this 
clinical trial and has taken trial medication, the Investigator must report immediately (within 24 
h) a potential drug exposure during pregnancy (DEDP) in a female patient or in a partner to a 
male patient to the sponsor’s unique entry point (country-specific contact details will be provided 
in the ISF). 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 (S)AE Reporting 
Disease Progression in oncology trials is a study endpoint for analysis of efficacy, and as such is 
exempted from being reported as an SAE. Progression of the patient's underlying malignancy will 
be recorded on the appropriate pages of the eCRF as part of efficacy data collection only and will 
not be reported on the SAE Form. It will therefore not be entered in the safety database (Adverse 
Reactions Information System global, ARISg) and hence not get expeditiously reported. Death 
due to disease progression is also to be recorded on the appropriate eCRF page and not on the 
SAE Form. 
Examples of exempted events of PD may be:

Progression of underlying malignancy (Progressive disease [PD]): if PD is clearly 
consistent with the suspected progression of AML 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 (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. 
However, when there is evidence suggesting a causal relationship between the trial drug and the 
progression of the underlying malignancy, the event must be reported as an (S)AE on the SAE 
Form and on the eCRF. 
5.2.3
Assessment of safety laboratory parameters
5.2.3.1
General safety laboratory parameters
Blood samples and urine have to be collected at the time points specified in the Flow Charts.  
Safety laboratory examinations will include hematology, biochemistry, coagulation and 
qualitative urine analysis:

during follow-up.
Biochemistry
Glucose, sodium, potassium, calcium, inorganic phosphate, 
creatinine, AST, ALT, alkaline phosphatase (AP), lactate 
dehydrogenase (LDH), bilirubin, urea, total protein, albumin, 
uric acid
Serum immunoglobulin levels (IgG, IgM, IgA) and direct 
antiglobulin test have to be measured only every 8 weeks, at 
the EOT visit and during follow-up.
Coagulation
Activated partial thromboplastin time (aPTT), prothrombin 
time (PT), international normalised ratio (INR) where 
indicated (e.g. treatment with vitamin K antagonists)
Urine
pH, glucose, erythrocytes, leukocytes, protein, nitrite will be 
analysed by dipstick and reported as semiquantitative 
measurements. In case of pathological findings, further 
evaluation should be performed and results documented.
Pregnancy test
A serum pregnancy test needs to be obtained at the time 
points indicated in the Flow Chart in patients of childbearing 
potential. 
An additional safety lab will be collected on day 2 of Cycle 1 (i.e., 24 hours after the first 
administration of BI 836858). Other lab tests to be included: haptoglobin, direct antiglobulin
test, bilirubin (direct and indirect) and free hemoglobin. Non pre-existing abnormal 
laboratory values (CTCAE Grade 3 or higher) will be followed up every 48 hours until these 
laboratory values are back to at least CTCAE Grade 1.
In case an administration is delayed due to an AE, the patient should visit the site at least 
once a week for assessment of safety laboratory and AEs. More frequent visits may be 
appropriate as assessed by the Investigator.
 
 
  
 
5.2.4
Electrocardiogram
A 12-lead resting ECG will be performed in all patients according to the schedule in the Flow 
Charts.  The ECG will be assessed for pathological results (to be recorded as either 
concomitant disease or AE) by the Investigator.  Additional examinations should be done 
whenever the Investigator deems necessary.

Assessment of other safety parameters
5.2.5.1
Vital signs
Vital signs (blood pressure, heart rate and body temperature) will be recorded at every visit 
during screening, treatment (including the EOT visit) and follow-up. Additional time points 
for blood pressure and heart rate at the day of administration of BI 836858 are: prior to the 
start of premedication, prior to the start of BI 836858 infusion, and in 30 (±10) minute 
intervals throughout the course of the infusion of BI 836858 and 60 (±10) minutes after the 
end of the infusion, thereafter every 4-8 hours until at least 24 hours after start of the
infusion. In case of an infusion-related reaction, the Investigator should decide whether to 
intensify or prolong monitoring of vital signs of the patient.
Beginning with infusion 2, blood pressure and heart rate will be assessed at the same time
points as during infusion 1 with the exception that they will not be assessed every 4-8 hours 
until at least 24 hours after the start of the infusion.
5.2.5.2
Physical examination
A physical examination including height, weight and ECOG performance score will be 
performed at screening and at the time points specified in the Flow Charts. During the 
physical examination, the patient should be assessed for possible AEs.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
During the treatment phase, patients with refractory or relapsed AML will receive 
administration with BI 836858 every 7 days.  For AML patients in CR, The first three 
administrations will be given once every second week on day 1 of Cycles 1, 2 and 3. From 
the 4th administration onwards, patients will receive monthly (every second cycle) infusions 
of BI 836858 (i.e. 4th infusion on Cycle 5 Day 1, 5th infusion on Cycle 7 Day 1 …) for overall 
up to 12 months of treatment.
Patients are required to be hospitalized under close surveillance with access to intensive care 
for at least 24 hours after the first administration of BI 836858 to allow close monitoring for 
infusion-related reactions or other AEs.  After good tolerability of the first administration of 
BI 836858, the Investigator may evaluate the risk for an infusion-related reaction and other 
AEs in view of relevant co morbidities or AML-related symptoms, and as a result, the patient 
may receive subsequent infusions in the out-patient setting.  
In case a patient misses a visit within one treatment cycle and the patient comes to the clinic 
between the missed and the next scheduled visit, the delayed visit should be scheduled as 
soon as possible and documented with the actual date and the reason for the delayed visit. 
The next visit, should still take place at the time it was originally scheduled in this treatment 
cycle.
However, in case the day of treatment administration (Visit 1 of a cycle) is delayed, all 
subsequent visits of a cycle will be recalculated based on the actual date of Visit 1 of the 
delayed cycle.

Follow up
Follow up (FU) visits will be performed for both patient populations.  These visits will occur 
after the patient has completed treatment according to protocol or is not eligible for further 
treatment cycles.  These follow-up visits will begin 4 weeks after the last infusion with BI 
836858.  In patients with AML in CR, follow-up visit 1 (FU1) is the same as EoR. Follow up 
will end in case the patient is lost to follow-up or in case the Investigator and Sponsor agree 
not to pursue further follow up visits.  Follow up visits should be performed at 4 week 
intervals or earlier if appropriate as determined by the Investigator.
Follow-up visits should be completed at the investigational site but may be performed by 
telephone interview in case the patient is unable to visit the Investigator.  Follow-up visits 
should be performed for 6 months after the last infusion with BI 836858.  At the last follow-
up visit, and end of trial assessment will be performed and documented in the eCRF.  For

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN - MODEL
This trial will be performed as an open-label study.  The primary objective of the trial is to 
determine the MTD of BI 836858 for both patient populations separately.  To determine the 
MTD, patients are entered sequentially into escalating dose tiers using the 3+3 design (see 
Section 3.1).  After the MTD has been determined, up to 12 patients for each patient 
population are additionally entered at this dose level to better characterize the safety of BI 
836858.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The analyses in this trial are descriptive and exploratory. No formal statistical tests will be 
performed.
7.3
PLANNED ANALYSES
For the determination of the MTD, only MTD evaluable (i.e. non-replaced patients) will be 
considered. 
For the analysis of secondary 
 all patients in the 
treated set (i.e. patients treated with at least one dose of BI 836858) will be included in the 
analysis, including the patients who have been replaced for any reason (see Section 3.3.4.1).
7.3.1
Primary analyses
The primary objective for this study is to identify the MTD (for both patient populations 
separately) and to investigate the safety profile of BI 836858. MTD is defined in Section 3.1, 
and will be identified by the occurrence of DLT in the dose escalation scheme. In order to 
identify the MTD, the number of patients with a DLT during the first two cycles at each dose 
level will be presented. Patients who discontinue during the first two treatment cycles for 
reasons other than DLT will be excluded from the determination of MTD. 
However, for those patients who receive more than two cycles of BI 836858, all AEs that 
constitute a DLT will be taken into consideration for the purpose of determining the 
recommended dose for the expansion cohort or the recommended dose for subsequent phase
II trial(s).
DLT is defined in Section 5.2.1.1. For the analysis of the tolerability and safety, please refer 
to Section 7.3.3.
The primary analysis will take place when all patients from the dose escalation and dose 
expansion cohorts have had a minimum of 4 cycles or have discontinued from the trial prior 
to reaching end of cycle 4 due to meeting the criteria for withdrawal as outlined in Section 
3.3.4.1.

In case patients are still being treated at the time of the primary analysis, a revised clinical 
trial report (CTR) will be created when the last patient has completed his/her last visit,
including all primary and secondary analyses.
7.3.2
Secondary analyses
This section outlines the analyses for the secondary 
 as 
defined in Section 5.1.1.
 
 
7.3.2.3
Best overall response
Each patient will be assigned to one of the response categories described in Section 5.1.2.3. 
Each patient’s best overall response will be used as a primary measure. To describe response 
over time, the proportion of patients in each response category will be tabulated at specified 
time intervals. The number of patients with objective response (best response of CR, CRi, or 
PR) will be summarized. Patients will be followed up for assessment of response and 
progression until they progress, receive any other anti-leukemia therapy, die, or until the trial 
ends. The observed length of follow-up and the number of patients available for analysis at 
each time point will determine the period of time covered in tables and figures.  Frequency 
distribution and other descriptive statistical measures will be used to examine these variables.
7.3.2.4
Progression free survival, time to treatment failure
These time-to-event variables will be analyzed with the Kaplan-Meier method.
In case there is no occurrence of death, progression or treatment failure until the last visit of 
the trial the time will be censored.  The percentage of patients who are event free will be 
displayed at monthly or greater time intervals as appropriate.  Details of censoring rules will 
be provided in the statistical analysis plan.
The cause of death will be summarized, along with whether death was plausible related to 
disease progression.

7.3.3
Safety analyses
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA) coding dictionary. Standard BI summary tables and listings will be produced. All 
adverse events with an onset between start of treatment and end of the residual effect period 
(REP), a period of 30 days after the last dose of trial medication, will be assigned to the 
treatment period for evaluation.
All treated patients will be included in the safety analysis. In general, safety analyses will be 
descriptive in nature and will be based on BI standards. No hypothesis testing is planned.
Statistical analysis and reporting of adverse events will concentrate on treatment-emergent 
adverse events. To this end, all adverse events occurring between start of treatment and end 
of the residual effect period will be considered ‘treatment-emergent’.  The residual effect 
period is defined as a period of 30 days after the last dose of trial. Adverse events that start 
before first drug intake and deteriorate under treatment will also be considered as ‘treatment-
emergent’.
Frequency, severity, and causal relationship of adverse events will be tabulated by system 
organ class and preferred term after coding according to the current version of the Medical 
Dictionary for Drug Regulatory Activities (MedDRA).
Laboratory data will be analysed both quantitatively as well as qualitatively. The latter will 
be done via comparison of laboratory data to their reference ranges. Values outside the 
reference range as well as values defined as clinically relevant will be highlighted in the 
listings. 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.
7.3.4
Interim analyses
The sponsor will continuously monitor safety. The dose escalation design foresees that 
regular safety evaluations are performed. These evaluations will be un-blinded to dose.
No formal interim analysis of efficacy data is foreseen, although efficacy data when available 
may be considered as part of the safety evaluations.

As patients with refractory or relapsed AML are known to have low monocyte counts and 
functional abnormalities of NK cells, both of which are required for the mode of action of   
BI 836858 (see Section 2.1), detailed evaluations will be performed to ensure a positive 
benefit-risk assessment in this patient population. If considered unjustifiable, treatment of 
patients with refractory or relapsed AML may be terminated based on these interim 
evaluations. 
Results of this evaluation of patients with refractory or relapsed AML will be documented 
and stored.  If applicable, the format and the detailed content of the analysis will be defined 
in the statistical analysis plan.
If considered necessary, a preliminary safety evaluation may also be performed in AML 
patients in CR.  This analysis will have no impact on the further conduct of the trial but can 
become necessary for internal project purposes.  Results of this evaluation will be 
documented and stored.  If applicable the format and the detailed content of such a 
preliminary analysis will be defined in the statistical analysis plan.

The occurrence of missing data should be minimized by follow-up of patients for both 
disease progression and mortality after end of trial for an individual patient. Both response 
and progression status for patients who are lost to follow-up or who die before progression 
has been documented, will be assessed at the end of the trial. 
Missing baseline laboratory values will be imputed by respective values from the screening 
visit.

RANDOMISATION
This is a non-randomized Phase I trial. All the patients will receive BI 836858.
7.6
DETERMINATION OF SAMPLE SIZE
Patients with refractory or relapsed AML:
Assuming 4 cohorts of 3 patients (i.e. no patients with DLT at given level) and 2 cohorts of 
6 patients (i.e. 1 DLT witnessed in first 3 patients so further 3 patients exposed with no 
DLTs), 24 evaluable patients will be necessary for the dose escalation part.
Together with an assumed number of 12 additional patients for the expansion cohort this 
leads to an expected sample size of 36 evaluable patients.
AML patients in CR:
Assuming 1 cohort of 3 patients (i.e. no patients with DLT at given level) and 2 cohorts of 
6 patients (i.e. 1 DLT witnessed in first 3 patients so further 3 patients exposed with no 
DLTs), 15 evaluable patients will be necessary for the dose escalation part in this patient 
population.
Together with an assumed number of 12 additional patients for the expansion cohort this 
leads to an expected sample size of 27 evaluable AML patients in CR.
Note that in general, the sample size is induced by the 3+3 design and is subject to different 
random factors.

INFORMED CONSENT, DATA PROTECTION, TRIAL
RECORDS
The trial will be carried out in compliance with the protocol, the principles laid down in the 
Declaration of Helsinki, in accordance with the ICH Harmonised Tripartite Guideline for 
Good Clinical Practice (GCP) and relevant BI Standard Operating Procedures (SOPs). 
Standard medical care (prophylactic, diagnostic and therapeutic procedures) remains in the 
responsibility of the treating physician of the patient.
The Investigator should inform the Sponsor immediately of any urgent safety measures taken 
to protect the study subjects against any immediate hazard, and also of any serious breaches
of the protocol/ICH GCP.
The rights of the Investigator and of the Sponsor with regard to publication of the results of 
this trial are described in the Investigator contract. As a general rule, no trial results should be 
published prior to finalisation of the Clinical Trial Report.
8.1
STUDY APPROVAL, PATIENT INFORMATION, AND INFORMED 
CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB) / Independent Ethics Committee 
(IEC) and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to patient participation in the trial, written informed consent must be obtained from each 
patient (or the patient’s legally accepted representative) according to ICH GCP and to the 
regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional patient-
information form retained by the Investigator as part of the trial records. A signed copy of the 
informed consent and any additional patient information must be given to each patient or the 
patient’s legally accepted representative.
The patient must be informed that his/her personal trial-related data will be used by 
Boehringer Ingelheim in accordance with the local data protection law. The level of 
disclosure must also be explained to the patient.
The patient must be informed that his / her medical records may be examined by authorized 
CML/Clinical Research Associate (CRA) or Clinical Quality Assurance auditors appointed 
by Boehringer Ingelheim, by appropriate IEC members, and by inspectors from regulatory 
authorities.
8.2
DATA QUALITY ASSURANCE
The trial will be conducted in compliance with the protocol, the principles laid down in the
Declaration of Helsinki (please, refer to Section 8), local law and according to the principles 
of GCP and the company SOPs. To inform all Investigators about the trial drugs and the

procedures of the trial, either an Investigator meeting will be performed prior to start of the 
trial, or each Investigator will be visited individually by the Clinical Monitor and the CRA. 
Each Investigator will receive an ISF with all information relevant for the performance of the 
trial. Investigators will be visited at regular intervals for on-site monitoring by a Boehringer
Ingelheim employee or a CRA authorised by BI. At these occasions, source data verification
(SDV) will be performed and a check will be done whether the eCRFs are kept current. The
information in the eCRF and information in source documents will be cross-checked as
described in Section 8.3.1.
The data management procedures to ensure the quality of the data are described in detail in
the trial data management and analysis plan (TDMAP) available in the Clinical Trial Master 
File (CTMF). Coding of the data obtained will be done by using the medical dictionary for 
regulatory activities (MedDRA) and the WHO dictionary for concomitant medication. Data 
quality review meetings will be performed at regular intervals to evaluate the quality of the 
data collected. Discrepancies in data will be queried. 
A quality assurance audit/inspection of this trial may be conducted by the Sponsor or 
Sponsor’s designees or by IRBs/IECs or by regulatory authorities. The quality assurance
auditor will have access to all medical records, the Investigator’s trial-related files and 
correspondence, and the informed consent documentation of this clinical trial.
8.3
RECORDS
Case Report Forms (CRFs) for individual patients will be provided by the Sponsor via remote 
data capture. For drug accountability, refer to Section 4.1.8.
8.3.1
Source documents
Source documents provide evidence for the existence of the patient and substantiate the 
integrity of the data collected. Source documents are filed at the Investigator’s site.
Data entered in the eCRFs that are transcribed from source documents must be consistent
with the source documents or the discrepancies must be explained. The Investigator may need 
to request previous medical records or transfer records, depending on the trial; also current 
medical records must be available.
For eCRFs all data must 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. 
CRFs/eCRFs 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 trial 
monitor, auditor and inspection by health authorities (e.g. FDA). The CRA / on site monitor 
and auditor may review all CRFs/eCRFs, and written informed consents. The accuracy of the 
data will be verified by reviewing the documents described in Section 8.3.1.

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 836858 this is the current version of the IB (c02324887-03). The current versions of 
these reference documents are provided in the ISF. 
8.4.2
Expedited reporting to health authorities and IECs/IRBs
Expedited reporting of SAEs, e.g. suspected unexpected serious adverse reactions (SUSARs) 
to health authorities and IECs/IRBs, will be done according to local regulatory requirements. 
Further details regarding this reporting procedure are provided in the ISF.
8.5
STATEMENT OF CONFIDENTIALITY
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.
Treatment data may be given to the patient’s personal physician or to other 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 IEC and the regulatory authority.

CLINICAL EVALUATION OF LIVER DISEASE
10.3.1
Introduction
Alterations of liver laboratory parameters, as described in Section 5.2.2.1 (Protocol-Specified 
Significant Events), are to be further evaluated using the following procedures:
10.3.2
Procedures
Repeat the following lab tests: ALT, AST, and bilirubin (total and direct) - within 48 to 
72 hours. If ALT and/or AST >3-fold ULN combined with an elevation of total bilirubin 
>2-fold ULN are confirmed, results of the laboratory parameters described below must be 
made available to the Investigator and to BI as soon as possible.
In addition,

obtain a detailed history of current symptoms and concurrent diagnoses and medical 
history according to the “Drug Induced Liver Injury (DILI) checklist” provided in the 
ISF

obtain history of concomitant drug use (including non-prescription medications, 
herbal and dietary supplement preparations), alcohol use, recreational drug use, and 
special diets according to the “DILI checklist” provided in the ISF; 

obtain a history of exposure to environmental chemical agents (consider home and 
work place exposure) according to the “DILI checklist” provided in the ISF; and 
report these via the CRF.
Clinical chemistry
Alkaline phosphatase, albumin, PT or INR, CK, CK-MB, coeruloplasmin, α-1 antitrypsin, 
transferin, amylase, lipase, fasting glucose, cholesterol, triglycerides
Serology
Hepatitis A (Anti-IgM, Anti-IgG), Hepatitis B (HbsAg, Anti-HBs, DNA), Hepatitis C 
(Anti-HCV, RNA if Anti-HCV positive), Hepatitis D (Anti-IgM, Anti-IgG), Hepatitis E 
(Anti-HEV, Anti-HEV IgM, RNA if Anti-HEV IgM positive), Anti-Smooth Muscle antibody
(titer), Anti-nuclear antibody (titer), Anti-LKM (liver-kidney microsomes) antibody, 
Antimitochondrial antibody
Hormones, tumor marker
TSH
Haematology
Thrombocytes, eosinophils

Provide abdominal ultrasound to rule out biliary tract, pancreatic or intrahepatic
pathology, e.g. bile duct stones or neoplasm.

“In case no MTD is reached up to the highest 
planned dose (e.g., 320 mg), of  800 mg, 12 
additional patients will be treated with once weekly 
highest test dose (i.e., 320 mg) 800 mg of 
BI 836858.”
Clarification of treatment in the dose escalation 
phase of the trial as follows:
“During the dose escalation phase, each patient 
will receive up to 2 repeated treatment cycles. In 
patients who show clinical benefit as defined by 
IWG objective response (CR, CRi, PR), or 
subjective response (in the absence of objective 
response) as defined by the Investigator after 2 
cycles, the number of cycles on the same dose level 
may be increased to 4 (8 administrations) upon 
agreement between Investigator and Sponsor. This 
includes Cycle three (administration of BI 836858 
on Days 29 and 36) and cycle four (administration 
of BI 836858 on Days 43 and 50). Continuation of 
treatment will be discussed between Investigators 
and Sponsor at each cycle.”
Text has been revised as follows:
Patients who show “clinical benefit”, (CR, CRi, PR, 
or subjective response) clinical benefit as defined by 
the Investigator after 4 cycles “(each cycle 
individually evaluated)),” and who are tolerating 
the infusions well may continue to receive

Clarification, update and safety.
To control the WBC, a treatment with hydroxyurea 
is allowed (as noted in Exclusion #3). The parallel 
use of hydroxyurea may allow patients with a 
proliferative disease to remain on study. This may 
also reduce the number of early study withdrawals, 
especially in the lower dose cohorts, as disease 
progression may be controlled.

Table 4.1.1: 1 was removed and text was added as 
explanation for infusion rate as follows:
“The first and second infusion will be started at a 
rate of 10 mL/h. The infusion rate should be 
increased every 30 (+/-10) minutes by 10 mL/h to a 
maximum of 80 mL/h as long as tolerated by the 
patient. If considered safe by the Investigator, the 
stepwise increase of infusion rate during the third 
and subsequent infusions may be faster or steps may 
be omitted, but the maximum infusion rate must not 
exceed 120 mL/h. If symptoms of an infusion-related 
reaction occur, the infusion should be temporarily 
stopped. Upon recovery, it should be infused at 50% 
of the rate at which the reaction occurred and 
should not be dose escalated from this dose for at 
least 30 minutes. Lower rates may be selected if 
clinically indicated. Depending on the time of 
occurrence and the severity of the reaction, the 
investigator may consider administering additional

supportive medication, e.g. corticosteroids. A 
stepwise re-increase of the infusion rate to a 
maximum of 80 mL/h is possible. For medical 
reasons, in case a patient experiences an adverse 
event during the infusion, the duration of the 
infusion may be expanded until the use-by date and 
use-by time indicated on the label is reached. The 
actual duration of the infusions and the infusion 
steps need to be documented in the eCRF including 
actual start and end time, actual time points for 
interruption and restart of the infusion and the 
actual infusion rates.”
Rationale for change
Clarification and Update.
The stepwise increase of the infusion rate of BI 
836858 was adapted and an upper limit of 80ml/hr 
is defined in the protocol amendment. However,
some flexibility is given in case the first four 
administrations of BI 836858 are well tolerated.

infusion as noted in Table 4.1.1: 1 over 3 hours 
every 7 days.”
The text referring to dose levels was modified: “The 
dose is planned to be escalated in cohorts at pre-
defined dose levels based on a multiplication factor 
of 2. 3 in the low dose range, and a factor of 
approximately 2 at doses higher than 90 mg.  The 
dose levels are 10 mg, 30 mg, 90 mg, 200 mg, 400

therapy must have been discontinued at least two 
weeks before the first administration of the trial 
drug (Hydroxyurea may be given during study 
participation) until 48 hours before the first 
treatment with BI 836858) and the patient must 
have recovered from all clinically relevant 
reversible toxicities as determined by the 
investigator.  
“For peripheral blood blast control, as this may 
correlate with the risk of occurrence of infusion 
related symptoms, hydroxyurea will be allowed 
(maximum dose of hydroxyurea 3gm daily) before 
and during study participation. Leukocyte must be 
≤ 5,000/µl at start of each administration of BI 
836858. During the first two dose cohorts, if in the 
first cycle more than 2 patients who receive 
BI 836858 experience a leukocyte count over 
40,000/µl indicative of disease progression, then 
hydroxyurea will be allowed (maximum dose of 
hydroxyurea 3gm daily) during the week after the 
first infusion of BI 836858 for all subsequent 
patients.
If the change of permitting hydroxyurea is 
implemented and more than 2 of the next 6 patients 
experience the leukocytosis (40,000/µl indicative of 
disease progression) and discontinue the due to 
disease progression in the first cycle, then the 
eligibility criteria will be modified such that patients 
requiring hydroxyurea within a week of study entry 
to maintain WBC <30,000/ul will no longer be 
eligible.
