Conditions: Leukemia, Myeloid, Acute
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 180
Healthy volunteers: no

Brief summary:
The trial will be performed in two parts, a phase I part and a phase IIa part. In the phase I part of the trial, BI 6727 will be investigated as monotherapy and in combination with low dose cytarabine (LD-Ara-C) in patients with relapsed/refractory AML that are not eligible for intensive treatment. The dose of BI 6727 will be escalated to determine the maximum tolerated dose (MTD) of BI 6727 monotherapy and BI 6727 in combination with LD-Ara-C in AML patients. In the phase IIa part, the combination of BI 6727 at MTD with LD-Ara-C and LD-Ara-C monotherapy will be investigated to explore the efficacy of the combination schedule in comparison to LD-Ara-C monotherapy in previously untreated AML patients that are not eligible for intensive treatment.

INTRODUCTION
1.1
MEDICAL BACKGROUND
Acute myeloid leukaemia (AML) is a heterogeneous clonal disorder of haematopoietic 
progenitor cells and represents the most common malignant myeloid disorder in adults. AML 
predominantly affects older adults with median age at diagnosis of about 70 years. Without 
therapeutic intervention the disease progresses and leads to death within months after initial 
diagnosis (R07-2768).
Genetic alterations in leukaemic cells constitute the most important factor for the prognosis 
of AML (R07-2768, R07-2770, R07-2774). AML patients are classified in groups of 
favourable, intermediate, and unfavourable 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, remission induction treatment, most commonly consists of cytarabine and an 
anthracycline and is followed by the second phase of post-remission treatment aiming at the 
consolidation of remission. AML patients under the age of 60 years achieve complete 
remission (CR) with intensive treatment regimens in up to 75%, 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).
However, while the majority of younger AML patients receives intensive treatment, a 
substantial number of elderly patients is 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 for the 
entire group of elderly AML patients. For AML patients considered ineligible to receive 
intensive treatment investigational treatment is widely regarded as the preferred therapeutic 
option (R07-2769, R07-2772). For most patients with relapsed AML or AML refractory to 
induction treatment no satisfactory therapy exists. Currently, major efforts focus on the 
improvement of the therapy in these subgroups of patients with unfavourable prognosis.
Although patients that 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 regularly done for every single patient based on the specialised
physician's clinical experience and the comprehensive review of factors like patient age,
performance score, organ dysfunctions and co-morbidities, as well as the patient's informed 
decision.

DRUG PROFILE
1.2.1
BI 6727
BI 6727 is a highly selective and potent small molecule Polo-like kinase 1 (Plk-1) inhibitor. 
The pharmacological profile of BI 6727 was evaluated in vitro in enzymatic assays, cellular 
cytotoxicity assays and assays examining cell cycle progression. In vivo efficacy of BI 6727 
was determined in human tumour xenografts in nude mice. 
In an enzymatic assay using human recombinant Plk-1 the molecular potency of BI 6727 was 
in the low nanomolar range. More than 45 kinases tested in parallel with Plk-1 were not 
inhibited, demonstrating the high molecular specificity of the compound. The compound was 
also tested for its cellular activity on a panel of tumour cell lines. Cytotoxicity in vitro and 
inhibition of Plk-1 in enzymatic assays was achieved at comparable concentrations. Activity 
was not dependent on cellular origin or molecular phenotype. Cell biological profiling 
revealed that BI 6727 induced a typical Plk-1 mitotic arrest phenotype (G2/M arrest, 
abnormal mitotic figures) at similar concentrations. When comparing the activity in parental 
cell lines to the activity in the respective chemo-resistant counterparts activity of BI 6727 was 
much better conserved than the activity of conventional chemotherapeutics such as taxanes or 
vincristine.
Efficacy of BI 6727 was shown in various xenograft models. Tumour regression up to 
complete cures of animals was demonstrated. Tumour regression was also shown in models 
of larger tumours. Doses shown to be effective were well tolerated and were administered to 
nude mice 1-2 times per week intravenously. 
The non-clinical safety profile of BI 6727 is considered favourable regarding the oncological 
indication and the antiproliferative principle. In 3-cycle toxicity studies in dogs and rats 
mechanism-related side effects were observed in organs with high turnover as expected. Main 
target organs were the gastrointestinal tract (mucosal lesions), bone marrow and lymphatic 
system. Complete reversibility even of severe lesions at higher doses was observed. 
Moreover, no evidence for unspecific toxicity affecting other organs such as kidney or liver 
was found. However, an exploratory investigation on the cardiovascular system in pigs, given
at very high doses of up to 30 mg/kg BI 6727, showed that BI 6727 induced QT prolongation 
starting at a plasma level of 3700 nmol/L and slight QTcSE prolongation in chronically 
treated dogs starting at 36 mg/m2 at plasma levels of about 880 – 1090 nmol/L. The hERG 
channel was inhibited with an IC50 value of 2.4 μmol/L while the action potential in guinea 
pig papillary muscle was not affected up to 10 μmol/L. Based on these results, QT-
monitoring is continued in the clinical phase II trials with BI 6727. More detailed information 
is provided in the Investigator’s Brochure (IB; c01694302-14).
To date 50 patients with a variety of tumour types have been treated in a phase I trial with BI 
6727. Thirty-one patients were treated at doses at or above 300 mg, with the maximum 
tolerated dose (MTD) at 400 mg. The results demonstrated that BI 6727 had good tolerability 
with reversible haematotoxicity (neutropenia, thrombocytopenia) constituting the dose 
limiting toxicity. No relevant unspecific toxicity has been observed as yet. Encouraging signs 
of efficacy were seen in two patients with confirmed partial regressions of urothelial and

ovarian tumours, respectively. In addition long term disease stabilizations were observed in 
several patients. More than 20 courses of treatment were given without signs of persisting or 
cumulative toxicity.
In the electrocardiogram (ECG) monitoring BI 6727 dose dependant QtcF prolongations at 
the time of Cmax have been observed in patients, but no associated clinical events were 
reported.
By virtue of a different therapeutic principle, new classes of drug substances may be 
promising either as monotherapy or in combination with already available drugs. In this trial, 
the safety and efficacy of BI 6727 will be tested in combination with and in comparison to 
low-dose cytarabine, the most widely established treatment for patients considered ineligible 
for intensive treatment (R07-2771); furthermore, in patients with relapsed/refractory AML 
BI 6727 monotherapy will be investigated.
1.2.2
Cytarabine
Cytarabine (1-beta-D-Arabinofuranosylcytosin) is indicated alone or in combination with 
other antineoplastic agents for induction of remission and/or maintenance treatment in 
patients with AML.
Cytarabine (Ara-C) is metabolised in vivo to Ara-CTP (arabinoside cytosine triphosphate)
phosphorylated compound, which competitively inhibits DNA polymerase and may also 
inhibit certain acid kinases. Primarily the drug acts as a false nucleoside and competes for 
enzymes involved in the conversion of cytidine nucleotide to deoxycytidine nucleotide and 
also incorporation into the DNA. Cytarabine is a cell cycle specific antineoplastic drug and 
has no effect on non-proliferating cells nor on proliferating cells unless in the S phase.
The major adverse effect of cytarabine is haematological toxicity. Furthermore, 
gastrointestinal toxicity may also occur. Other reported adverse effects of cytarabine include 
fever, rash, alopecia, skin ulceration, conjunctivitis, chest pain, urinary retention, dizziness, 
neuritis, neurotoxicity or neural toxicity and pain, cellulitis and thrombophlebitis (including 
irritation or sepsis) at the site of injection. Cytarabine has also been associated with renal 
dysfunction, hepatic dysfunction and jaundice in some patients. It has also been associated 
with freckling, skin and mucosal bleeding, joint pain. Very rare cases of pericarditis have 
been reported. Cases of pancreatitis have also been reported. 
A cytarabine reaction is characterised by fever, myalgia, bone pain, occasionally chest pain, 
maculopapular rash, conjunctivitis and malaise. It usually occurs 6-12 hours after 
administration.
Cytarabine is teratogenic in some animal species. It should not be used in pregnant women. It 
should not be used in women who may become pregnant, unless a medically acceptable 
method of contraception is used during the trial. It is not known if cytarabine or its metabolite 
is distributed into breast milk, therefore it should not be used in breastfeeding women.

provided by the manufacturer.

1.3
RATIONALE FOR PERFORMING THE TRIAL
New therapeutic strategies are needed to significantly improve the prognosis of AML patients 
assessed ineligible for intensive treatment at initial diagnosis as well as for patients with 
relapsed/refractory AML. 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 inhibitory molecules.
The Plk-1 is a key enzyme regulating the processes during the metaphase of mitosis and BI 
6727 specifically inhibits Plk-1. Although not specific for acute leukaemia, molecules 
targeted to disturb cellular division and to induce apoptosis are especially promising in 
rapidly proliferative malignancies such as AML.
To maximize the chance of significant therapeutic improvement BI 6727 will be combined 
with and compared to low-dose Cytarabine (LD-Ara-C). LD-Ara-C was investigated in a 
randomized trial in AML patients ineligible for intensive treatment, since then LD-Ara-C has 
been widely used in this patient group (R07-2771). 
After implementation of Protocol Revision I, based on BI’s decision to discontinue the
development of volasertib, one ongoing patient with clinical benefit from volasertib based on 
investigator´s assessment will stay in this trial to continue treatment with volasertib until 
disease progression or withdrawal from treatment and safety follow-up measures are 
completed. No documentation of volasertib effects in the eCRF will take place other than 
safety monitoring. Assessment of benefit from treatment will be performed per local standard 
of practice to support the decision on further treatment with volasertib. The results should be 
recorded in the source data only; documentation of efficacy results in the eCRF is no longer 
required.
1.4
BENEFIT - RISK ASSESSMENT
Patients with AML that are considered ineligible for intensive treatment at initial diagnosis as 
well as patients with relapsed/refractory AML have an overall adverse prognosis with very 
limited treatment options. LD-Ara-C is an established treatment for these patients, but 
outcome results are not satisfactory; in previously untreated patients considered ineligible for 
intensive treatment complete remissions up to 18% (R07-2771) were reported with LD-Ara-C 
treatment.
As no objective criteria are established to assess a patient's eligibility for intensive treatment 
the decision which treatment to adopt is based on the specialised investigators medical 
experience. To allow continuous monitoring and periodic reporting of the reasons why 
patients are assessed ineligible for intensive treatment the rationale for decision-making will 
be documented by the investigator for every single patient entered in the trial.
The most relevant side effect of BI 6727 administration is expected to be a transient 
inhibition of proliferation of normal dividing cells in bone marrow and mucosal tissue. 
Thymic atrophy seen in toxicological studies is not deemed relevant in the target population 
of adult cancer patients. Inhibition of mucosal proliferation may lead to gastrointestinal 
symptoms such as nausea or diarrhoea. The side effects on bone marrow stem cells may lead

to a temporary decrease of blood cells and platelets. These side effects are frequently seen in 
cancer patients treated with conventional cytotoxics or targeted therapies and can easily be 
monitored. Supportive treatment for these effects is available. In contrast to many established 
antiproliferative agents no unspecific toxic effects have been identified for BI 6727 in 
preclinical studies. AML patients often present with disease-related cytopenias, which 
without effective therapy will aggravate as the disease progresses. For most anti-leukaemia 
therapeutics, a drug-related transient worsening of cytopenias is common and inevitable. As 
described above, transient cytopenias are expected to occur with BI 6727. Cytarabine 
treatment is known to cause toxicities that overlap with BI 6727. Therefore, the CTCAE
(common terminology criteria for adverse events) grade and duration of cytopenias and 
gastrointestinal toxicity will be important safety criteria to limit the risk of the treatment with 
the trial drugs (see section 5.2).
QT-monitoring will be performed in this trial, although the QT-prolongation observed at high 
doses in an animal model are not expected to impair clinical development of the compound.
In summary, the adverse event profile of BI 6727 as monotherapy as well as in combination 
with cytarabine is expected to be acceptable in the treatment of AML patients ineligible for 
intensive treatment, as these patients have an adverse prognosis, the effect of other therapies 
(e.g. LD-Ara-C) is limited, and the risk of fatal outcome within one year of diagnosis is high. 
For these AML patients the potential benefit of the investigational treatments may outweigh 
the risks associated with the therapy.

TRIAL OBJECTIVES
2.1
GENERAL AIM - OBJECTIVES
The trial will be performed in two parts, a phase I part and a phase IIa part.
In the phase I part of the trial, BI 6727 will be investigated as monotherapy and in 
combination with low dose cytarabine (LD-Ara-C) in patients with relapsed/refractory AML 
that are not eligible for intensive treatment. First the dose of BI 6727 will be escalated to 
determine the maximum tolerated dose (MTD) of BI 6727 in combination with LD-Ara-C 
(treatment schedule A) in AML patients. A safety analysis and conclusion on the MTD based 
on a database snapshot will be performed after the primary endpoint (MTD) of the phase I 
part was reached in treatment schedule A. The selection of the recommended dose for the 
phase II part of the trial will be based on the MTD and will furthermore account for the safety 
observed during treatment beyond the 1st cycle. The risk-benefit assessment will be updated 
if necessary (see section 7.3.4). After determination of the MTD in schedule A, patients will 
be recruited to schedule B (BI 6727 monotherapy); starting from the BI 6727 dose 
determined as MTD in schedule A the dose of BI 6727 will be further escalated to determine 
the MTD of BI 6727 monotherapy  in AML patients.
In the phase IIa part, the combination of BI 6727 either at MTD or at another recommended 
dose for phase II with LD-Ara-C and LD-Ara-C monotherapy will be investigated to explore
the efficacy of the combination schedule in comparison to LD-Ara-C monotherapy in 
previously untreated AML patients that are not eligible for intensive treatment.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN - DESCRIPTION
The trial is performed according to an open randomised design. The data obtained from this 
trial shall allow the definition of an MTD for two treatment schedules, one consisting of BI 
6727 in combination with LD-Ara-C and one consisting of BI 6727 monotherapy. 
Furthermore, this trial shall allow an explorative analysis whether BI 6727 in combination 
with LD-Ara-C is effective compared to the established LD-Ara-C monotherapy. The results 
of the trial should help to decide on the further development programme of the BI 6727 in 
this indication.
Adult patients with relapsed/refractory AML who are considered ineligible for intensive 
treatment will be eligible for treatment in the phase I part of the trial. AML Patients with 
previously untreated AML will be eligible for the phase IIa part of the trial if they are 
considered ineligible for intensive treatment. After review of the inclusion and exclusion 
criteria, patients will be randomised / assigned to one treatment schedule. In the phase I part 
of the trial, patients will be assigned to schedules A and B. Schedule A patients will receive 
BI 6727 on days one and fifteen (1 hours i.v.) combined with LD-Ara-C (2 x 20 mg/d s.c.) on 
days 1-10 of a 4-week treatment cycle while schedule B patients will receive BI 6727 on days 
one and fifteen as monotherapy. The starting dose of BI 6727 in schedule A will be 
150 mg/administration. After determination of the MTD for schedule A, patients will be 
recruited for dose escalation in schedule B (BI 6727 monotherapy), starting from the BI 6727 
dose determined as MTD in schedule A. After determination of the MTD for schedule A and 
after review of the phase I safety analysis by the Clinical Monitor and the Coordinating 
Investigator, and if appropriate an updated risk-benefit assessment (see section 7.3.4), the 
phase IIa part of the trial will be opened. The safety analysis together with the conclusion on 
the recommended dose for the phase IIa part will be distributed to all involved competent 
authorities, ethics committees, and participating investigators prior to the initiation of the 
phase IIa part of the trial. Patients will be recruited to the phase II part of the trial only if a 
favourable risk-benefit assessment persists after the phase I safety analysis. In the phase IIa 
part of the trial patients will be randomised into one of the two schedules: A = BI 6727 d 1/15 
+ LD-Ara-C or C = LD-Ara-C monotherapy (control).

After the MTD has been determined in treatment schedule B, up to 15 additional patients 
with relapsed/refractory AML will be recruited to treatment schedule B to receive BI 6727 
monotherapy.
To determine the MTD, dose escalation will be conducted for each treatment schedule
following the 3+3 design as described in 4.1.3 (R04-0569). Briefly, cohorts of three patients 
will be treated per dose tier. The dose for BI 6727 will be escalated by up to 50 mg per 
administration until the highest dose has been found at which no more than one out of six 
patients experience a DLT. After definition of the MTD in schedule A and the phase I safety 
analysis (see section 7.3.4) the phase IIa part of the trial will start. In the phase IIa part 43
patients will be treated at the defined MTD of BI 6727 in combination with LD-Ara-C, and 
another 43 patients will be entered to the control group receiving standard LD-Ara-C 
monotherapy.
In the phase I part of the trial intrapatient dose escalation of BI 6727 will be allowed in 
patients who continue therapy beyond the first cycle as described in section 4.1.4.
During treatment, the investigator will determine the safety laboratory parameters, record the 
adverse events, and perform additional investigations as outlined in the flow charts. 
Assessment of response will be performed at the investigator site and will be sufficient for 
the decision whether the patient will continue treatment. After implementation of Protocol 
Revision I, assessment of response will only have to be done per local standard of practice to 
support the investigator´s decision on treatment continuation/discontinuation. Safety 
laboratory parameters and additional investigations as outlined in the flow chart will be done 
as medically indicated at discretion of the investigator.
The duration of one treatment cycle will be four weeks, including the days of treatment 
administration, unless haematologic toxicities necessitate an additional observation period of 
up to three weeks (for details see 4.1.4). At the end of each cycle, the decision will be made 
about continuation of treatment or withdrawal according to the criteria specified (sections 
4.1.4 and 6.3).
The trial will be performed by investigators experienced and specialised in the treatment of 
AML. These investigators are trained to assess a patient's eligibility for intensive treatment -
based on their special medical experience. The criteria impacting the decision to assess a 
patient ineligible for intensive treatment will be documented to allow continuous monitoring 
and to enable periodic reporting of the rationale to enter patients into the study. 
The safety laboratory investigations will be performed at the investigator site and no central 
laboratory will be used except for pharmacokinetic, pharmacodynamic 
(immunocytochemistry), cytogenetic/molecular genetic and pharmacogenetic analyses. A 
vendor will be used for centralised ECG analysis. After implementation of Protocol Revision 
I, ECG readings prior to volasertib infusion and at the end of infusion will continue to ensure 
patient safety, but centralised ECG analysis will be discontinued.
The trial drugs will be forwarded by Boehringer Ingelheim to the investigators’ pharmacies 
where they will be stored according to the storing condition requirements. Upon request of

the investigator the trial drugs will be prepared by the investigator’s pharmacy for an 
individual patient and forwarded to the investigator.
All trial relevant documentation will be stored in BI’s clinical trial master file (CTMF). Trial 
relevant documentation which has to be at the trial site will be filed in the investigator site 
file (ISF) at the investigator site.
The co-ordinating investigator who finally shall sign the clinical trial report of this trial has 
been elected by Boehringer Ingelheim. The co-ordinating investigator is one of the 
investigators participating in the trial and has experience in this type of trials and 
investigations.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
In the phase I part of the trial the investigational drug BI 6727 will be administered either as 
monotherapy or in combination with LD-Ara-C to patients with relapsed/refractory AML 
ineligible for intensive treatment. To determine the MTD (for definition see 5.2.4), dose 
escalation for BI 6727 will be conducted following the “3 + 3 design with de-escalation” (for 
details see section 4.1.3). A phase I safety analysis will be performed before start of the phase 
IIa part (see section 7.3.4). Patients will be recruited to the phase IIa part of the trial only if a 
favourable risk-benefit assessment persists after the phase I safety analysis.
In phase IIa of the trial, patients with previously untreated AML considered ineligible for 
intensive treatment will be randomised to receive BI 6727 at MTD in combination with LD-
Ara-C or LD-Ara-C monotherapy. LD-Ara-C is considered an established treatment for 
patients with AML who are ineligible for intensive treatment (R07-2771).
This trial will be performed according to an open design, because placebo-infusions / 
injections, which would be necessary for blinding, are considered dispensable in this phase 
I/IIa exploratory trial (see section 4.1.5).
The primary objectives of the trial are to establish separately the MTD for BI 6727 
monotherapy and BI 6727 in combination with LD-Ara-C in AML patients (phase I part), and 
to obtain a signal whether BI 6727 in combination with LD-Ara-C is effective in the 
treatment of AML as compared to the established LD-Ara-C monotherapy (phase IIa part).
Adult AML patients who have relapsed or failed prior chemotherapy and are considered 
ineligible for an intensive treatment were selected for inclusion in the phase I part of this trial, 
because these patients constitute a group with unfavourable prognosis for whom currently no 
satisfactory standard treatment exists.
Adult patients with previously untreated AML who are considered ineligible for intensive 
treatment were selected for inclusion in the phase IIa part this trial. LD-Ara-C is an 
established treatment for this group of patients, but outcome results are not satisfactory.
At the screening visit and before a patient is enrolled in the trial the investigator will
document comprehensively the reasons why the patient is considered ineligible for intensive 
treatment (section 5.3.3).

The trial shall allow the investigation of BI 6727 and BI 6727 + LD-Ara-C in AML with 
regard to safety and efficacy for the future clinical development programme in this disease
and possibly other malignancies.
The likelihood of any monotherapy to improve on the outcome of AML patients is considered 
low at this time. Therefore BI 6727 will be tested in combination with the established 
compound cytarabine in the phase II part of the trial. Still BI 6727 monotherapy will be 
evaluated in the phase I part of the trial to generate safety, pharmacokinetic and 
pharmacodynamic data for BI 6727 in this indication. If warranted by efficacy data of BI 
6727 monotherapy phase II development of BI 6727 monotherapy may be considered in 
addition.
To avoid potential bias at inclusion, in the phase II part the patients will be randomly 
allocated to the treatment schedules. The trial will be performed in an open-label manner (see 
also section 4.1.5).
3.3
SELECTION OF TRIAL POPULATION
A total of about 175 evaluable patients are planned. As in the phase I part of the trial (dose 
escalation) at most 6 patients per month can be recruited, this part of the trial will be 
performed at up to eight trial sites. The phase IIa part of the trial will be performed at least at 
twenty trial sites. Each site is expected to recruit about one patient every month. A log of all 
patients screened will be maintained in the ISF at the investigational site.

4.1.2
Method of assigning patients to treatment groups
Patients will be assigned to two treatment schedules (A and B) in the phase I part of the trial 
(dose escalation phase to determine MTD) as follows: patients will first be entered in 
treatment schedule A. After determination of the MTD for schedule A, patients will be 
recruited for dose escalation in schedule B (BI 6727 monotherapy).
In the phase IIa part of the trial (after MTD in schedule A is determined), patients will be 
randomised to two treatment schedules (A and C). 
Random allocation will be performed using randomisation envelopes (for details see section 
7.5).
4.1.3
Selection of doses in the trial
Two treatment schedules will be investigated in the phase I part of the trial to determine the 
MTD. All patients will receive either BI 6727 on days 1 and 15 either as monotherapy or in 
combination with LD-Ara-C (2 x 20 mg/d on days 1-10) in 28-day cycles. The starting dose 
of BI 6727 in treatment schedule A is 150 mg and corresponds to 50 % of the recommended 
Phase II dose of 300mg and 38% of the MTD of 400mg that has been determined in a phase I 
monotherapy dose escalation trial to be well tolerated. 
To determine the MTD (for definition see 5.2.4), dose escalation for BI 6727 will be 
conducted following the “3 + 3 design with de-escalation” (R04-0569). A cohort of three 
patients will be treated at the starting dose level and observed until the end of the cycle. The 
dose level will be escalated with each new cohort until at least one out of three patients of a 
cohort experiences DLT (for definition see section 5.2.3). If one patient experiences a DLT, 
then three additional patients will be treated at the same dose level; if none of the three 
additional patients experiences a DLT, then the dose escalation will be continued by treating 
the next cohort of 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). A dose step for escalation shall not exceed 50 mg/administration, a 
dose step for de-escalation shall not exceed 50 mg/administration. 
The starting of BI 6727 for dose escalation in schedule B will be the dose determined as 
BI 6727 MTD in schedule A.
The dose of the trial drug on days one and fifteen will always remain the same (i.e. 
simultaneous and equal dose escalation for days one and fifteen). The dose of cytarabine 
remains always unchanged.
In case two or more cases of DLT are observed at the starting dose of 150 mg either in 
monotherapy or in combination with LD-Ara-C the dose BI 6727 will be deescalated to a 
lower dose cohort as outlined above. 
After the MTD has been determined in treatment schedule A, a safety analysis based on a 
database snapshot will be performed (see section 7.3.4). Patients will be recruited to the 
second phase of the trial only after a favourable assessment in the phase I safety analysis. In 
this phase IIa part, patients will be randomised to receive either BI 6727 at MTD in 
combination with LD-Ara-C or LD-Ara-C monotherapy. 
After the MTD has been determined in treatment schedule B, up to 15 additional patients

with relapsed/refractory AML will be recruited to treatment schedule B to receive BI 6727 
monotherapy.
4.1.4
Selection and timing of doses for each patient
Prior to inclusion of a new patient in the phase I part the investigator has to confirm the actual 
dose tier of BI 6727 for the patient with the clinical monitor of the sponsor who oversees the 
dose escalation steps according to the safety data of patients from all trial sites.
BI 6727 will be administered as an intravenous infusion under the supervision of the 
investigator or designated personnel. Subcutaneous cytarabine injections will be administered
according to the SPC.
The trial drugs may be administered at any time during the day. In case the second dose of 
BI 6727 is missed for administrative reasons the respective dose will be administered on the
following two days. In case a dose of cytarabine is missed for administrative reasons the 
respective dose will not be administered at a later time (any missed cytarabine dose must be 
documented in the eCRF).
At the end of each treatment cycle, the response to treatment will be assessed. To continue
treatment with further cycles, the following criteria must be met:
1.)
Absence of disease progression (see section 5.1.1)
2.)
Neutrophils ≥ 500 /μL (0.5 x 109/L) and platelets ≥ 25,000 /μL (25 x 109/L);
unless CTCAE grade 4 neutropenia or thrombopenia was preexistent
3.)
Acceptable tolerability (in case of DLT, patients may continue therapy only after 
recovery from DLT to CTCAE levels which allow further therapy and only with a 
reduced dose), and recovery from drug-related cardiac toxicity.
In case criterion 2 is not fulfilled, the peripheral blood should be re-evaluated for up to three
weeks. As soon as criterion 2 is met the treatment should be continued (unless other criteria 
for discontinuation or withdrawal apply, see section 6.3). A delay of haematopoietic 
reconstitution (i.e criterion 2 unmet) for more than three weeks after the end of the treatment 
cycle qualifies for DLT in patients with CRi or PR (see section 5.2.3). Any case of a delay in 
treatment cycle should be communicated to the clinical monitor of Boehringer Ingelheim. 
Progressive disease will lead to discontinuation of treatment.
Administration of the trial drugs has to be stopped temporarily in case of a DLT (see section 
5.2.3). Patients may continue therapy only after recovery from the DLT to CTCAE levels 
which allow further therapy and only with a reduced dose of BI 6727, the LD-Ara-C dose 
will remain unchanged. The new dose of BI 6727 must be finally agreed on between the 
clinical monitor of Boehringer Ingelheim 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 6727 dose, the treatment has to be

permanently discontinued. Likewise, treatment has to be discontinued in case the DLT is not 
reversible.
In this trial, an intrapatient dose escalation of BI 6727 will be allowed in the phase I part of 
the trial to increase the probability of clinical benefit. In case of a clinical response other than 
CR or CRi (i.e. PR or no change), the patient may receive a higher dose of BI 6727 provided 
that the drug is tolerated well (i.e. non-haematological drug related adverse events CTCAE
grade ∀2 and haematological drug related adverse events CTCAE grade ∀3 unless 
preexistent). The BI 6727 dose escalation may be up to 50 mg/administration for both
schedules. All decisions on intrapatient dose escalation will be made only in agreement 
between the investigator and the sponsor. Beginning after the first cycle of treatment, dose 
escalations may be repeated after every cycle and may in individual patients exceed the MTD 
found in this trial. A dose escalation must not be performed in patients who have achieved 
CR or CRi.
All changes of the BI 6727 dose will simultaneously affect both days of BI 6727 
administration, i.e. BI 6727 dose will always remain the same on days one and fifteen.
4.1.5
Blinding
This phase I / IIa trial will be performed according to an open design. Although a double-
blind double-dummy design would be feasible, this would necessitate additional placebo-
infusions/injections which are considered dispensable in this phase I/IIa exploratory trial in 
these highly compromised patients. Without placebo-infusions/injections, the obvious 
difference in treatment schedules precludes blinding of both the patient and the investigator. 
Therefore, no blinding is done. For similar technical reasons, the statistical analyses will be 
performed in an open fashion.
This open-label trial will also be handled in an open fashion by the sponsor throughout. The 
eCRF will contain information on randomised treatment.
4.1.6
Packaging, labelling, and re-supply
BI 6727 will be supplied in 100 mL vials containing 200 mg BI 6727 OR in 175 mL vials 
containing 350 mg BI 6727.
Ara-C will be supplied in vials containing cytarabine at a concentration of 20 mg/ml.
BI 6727 will be labelled with trial number, medication number, quantity of dosage units and 
strength, identification code, pharmaceutical dosage form, route and mode of administration, 
term ‘for clinical trial use’ (domestic language), sponsor name and address, storage 
conditions, use-by-date.
In the phase I part of the trial cytarabine will be dispensed with the commercially available 
label and an additional label indicating trial number, medication number, term ‘for clinical

CONCOMITANT THERAPY
4.2.1
Rescue medication and additional treatments
Rescue medication to reverse the action of BI 6727 or cytarabine is not available. Potential 
side effects of BI 6727 and cytarabine have to be treated symptomatically. Patients should 
receive supportive care according to local guidelines regarding blood product support, 
antibiotics, analgesics, skin and mouth care etc. The use of growth factors such as 
granulocyte colony stimulating factor (G-CSF) will be allowed, but growth factors should be 
avoided in the first treatment cycle for better assessment of safety and response parameters. 
Treatment with corticosteroids will be allowed. All treatments have to be recorded in the
eCRF with duration. 
All concomitant non-antileukaemia therapies to provide adequate care may be given as 
clinically necessary but should be recorded in the eCRF except for vitamins or nutrient 
supplements. 
Trade name, indication and dates of administration of concomitant therapies will be 
documented. The use of prophylactic antiemetic drugs should be documented. For parenteral

nutrition during the trial, the components need not to be specified in detail. It should just be 
indicated as 'parenteral nutrition'. If a patient needs anaesthesia, it will be sufficient to 
indicate 'anaesthesia' without specifying the details.
4.2.2
Restrictions
During the trial, no additional chemo- or immunotherapy will be allowed. 
For patients included in the phase I part of the trial (relapsed/refractory AML) prior cytotoxic 
antileukaemia chemotherapy (except hydroxyurea) or antileukaemia immunotherapy must 
have been discontinued at least two weeks before the first administration of the trial drug and 
the patient must have recovered from all clinically relevant reversible toxicities. For any other
prior investigational treatment, a time interval of the investigational drug's half-life x5 must 
have elapsed from the last administration of the other investigational drug to the first 
administration of BI 6727.
For patients included in the phase IIa part of the trial (previously untreated AML) no prior 
chemo- or immunotherapy for AML is allowed (except hydroxyurea) before the 
administration of the trial drugs.
For peripheral blast control, hydroxyurea may be given until one day before the first 
administration of the trial drug in all patients. The start date, end date, and dose will be 
recorded in the e-CRF.
Concomitant therapy with other investigational drugs will not be allowed during the trial.
4.3
TREATMENT COMPLIANCE
BI 6727 will be administered as an intravenous infusion under the supervision of the 
investigator or designated personnel. Subcutaneous cytarabine injections will be administered
according to the SPC. The investigator or his/her deputy will check at visits 2, 3 and 4 
whether the patient has received the cytarabine medication according to the protocol on the 
scheduled previous days until day 10. Any discrepancies will be explained in the CRF by the 
investigator or his/her deputy. 
The plasma concentrations of the trial drugs will be determined.

OBSERVATIONS
5.1
EFFICACY - PHARMACODYNAMICS
The efficacy endpoints will be assessed at the time points specified in the flow charts. The 
primary endpoint for efficacy is response. Secondary endpoints for efficacy are event free 
survival, relapse free survival, remission duration, overall survival.
5.1.1
Assessment of response
Response will be assessed in the peripheral blood and in the bone marrow.
In case of extramedullary manifestations of leukaemia, assessment by imaging will 
complement the blood and bone marrow assessment of response.
The baseline bone marrow assessment should be done within 2 weeks prior to start of 
treatment with the trial drugs.
The first response assessment in the bone marrow will be performed at the end of the first 
treatment cycle. The classification of response is defined below.
Response assessment after further treatment cycles will be performed in a two step fashion to 
reduce patient stress:
!
First, the manifestation of leukaemia will be assessed clinically and in the peripheral 
blood. In case of persistence of leukaemia cells in the blood no bone marrow aspiration 
must be performed. 
!
If leukaemia cells cannot be detected in the peripheral blood and other clinical signs of 
active leukaemia are absent, a bone marrow aspirate will be obtained before the next 
treatment cycle.
If the bone marrow demonstrates CR or CRi, further bone marrow examination will be 
performed after every other treatment cycle.
In case of persistence of leukaemia in the bone marrow and continuing absence of 
leukaemia in the peripheral blood, further bone marrow examination will be performed 
after each treatment cycle to earlier detect CR or progressive disease.
!
A bone marrow examination should be performed as soon as possible when progressive 
disease or relapse after CR or CRi is suspected.
After approval of Protocol Revision I, bone marrow aspirations and disease assessments only 
have to be done per local standard of practice to support the decision on further treatment 
with volasertib. These efficacy data will not be entered in the eCRF; documentation in the 
source data is sufficient.
5.1.1.1
Definition of response
Response to treatment will be evaluated according to the following criteria (modified from 
the National Cancer Institute/Cancer and Leukemia Group B criteria, R06-0452):

!
Complete remission (CR)
morphologically leukaemia free state (i.e. bone marrow with < 5% blasts by morphologic 
criteria and no Auer rods, no evidence of extramedullary leukaemia) and absolute 
neutrophil count ≥ 1,000/μL and platelets > 100,000/μL.
!
Complete remission with incomplete blood count recovery (“incomplete” CR, CRi)
All of the above criteria for CR must be met, except that neutrophils < 1,000/μL or 
platelets < 100,000/μL in the blood.
!
Partial remission (PR)
All of the above criteria for CR must be met, except that the bone marrow contains ≥ 5% 
but less than 25% blasts (or ≤ 50% of initial blast count), or < 5% blasts in the presence of 
Auer rods or abnormal morphology.
!
No change
Patient survives ≥ 7 days following completion of initial treatment cycle with persistent 
leukaemia in the last peripheral blood smear or bone marrow (>25% blasts), or with 
persistent extramedullary disease, but without further clinical deterioration due to 
leukaemia or increase of blast population in the bone marrow or peripheral blood.
!
Progressive disease (PD)
Patient survives ≥ 7 days following completion of initial treatment cycle with increase of 
blast population in the bone marrow or peripheral blood or aggravation or new 
development of extramedullary disease or further deterioration or death due to leukaemia. 
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 ‘symptomatic 
deterioration’. Every effort should be made to document the objective pd even after 
discontinuation of treatment.
!
Aplasia
Patient survives ≥ 7 days following completion of initial treatment cycle, then dies while 
cytopenic, with the last post-treatment bone marrow aplastic or hypoplastic (i.e. <20% 
cellularity) and without leukaemia blasts.
!
Indeterminate
(a) Patient survives < 7 days after completion of initial treatment cycle; or (b) patient 
survives ≥ 7 days following completion of initial treatment cycle, then dies with no 
persistent leukaemia in the peripheral smear but no post-treatment bone marrow 
examination or (c) patient does not complete the first cycle
!
Recurrence (relapse)
after CR reappearance of leukaemic blasts in the blood or > 5% blasts in the bone marrow 
not attributable to any other cause.
Patients with the response status “aplasia” or “indeterminate” will be treated as non-
responders for primary statistical analyses of efficacy parameters.
5.1.2
Event Free Survival
Event free survival (EFS) is defined for all patients that entered the trial, and measured from 
the date of randomisation to the date of disease progression (treatment failure), relapse or 
death from any cause, whichever occurs first (R06-0452).

5.1.3
Relapse-free survival
Relapse free survival is defined only for patients who achieve CR, and is measured from the 
date of attaining CR until the date of disease recurrence or death from any cause, whichever 
occurs first.
5.1.4
Remission duration
Remission duration analysis is defined only for patients who achieve CR, and is measured 
from the date of attaining CR until the date of disease recurrence (relapse). For patients who 
die without report of relapse, remission duration will be censored on the date of death, 
regardless of cause.
5.1.5
Overall survival
Overall survival (OS) is defined for all patients that entered the trial, and measured from the 
date of randomisation until death from any cause.
5.2
SAFETY
5.2.1
Adverse events
Upon inclusion into the trial, the patient’s condition is assessed (e.g. documentation of 
history / concomitant diagnoses and diseases), and all relevant changes from baseline are
noted subsequently.
Patients will be required to report spontaneously any adverse events (AEs) as well as the date
of onset and end of these events. These include all events that affect the well-being of the 
patients irrespective of their relatedness to the treatment. Specific questions will be asked 
whenever required or useful to more precisely describe an AE and to allow a grading 
according to the CTCAE criteria (version 3, R04-0474).
A carefully written record of all AEs has to be kept by the investigator in charge of the trial. 
Records of AEs will include data on the date of onset, end date and CTCAE grading of the 
event as well as any treatment or action required for the event and its outcome.
The events leukopenia, neutropenia, thrombocytopenia are expected after treatment with BI 
6727 and will be considered as listed events for regulatory purposes (see IB for details, 
c01694302-14). The events listed in the SPC are expected after treatment with cytarabine.
AEs with onset within 21 days after the last trial drug administration in the last treatment 
cycle will be considered as on treatment. All AEs, including those persisting after trial 
completion must be followed up until they have resolved or have been sufficiently 
characterised or the clinical monitor and the investigator agree to not further pursue them.
All events, serious and non-serious, with onset within six weeks after the last application of 
the trial drug (observational phase) must be reported. All events, serious and non-serious, that 
are considered related to the trial drugs must be reported irrespective of the time of onset.

Deaths (unless they are considered drug-related or trial related) will not be reported as serious 
adverse events if occurring later than six weeks after last administration of the trial drugs, 
since death will be followed-up separately (secondary endpoints).
Definitions and requirements for documentation and reporting of AEs and serious adverse 
events (SAEs) during the trial are provided in Section 8.4.1.
Patients may be hospitalised for administrative reasons during the trial (e.g. days on which 
infusion of the trial drug takes place). These and other hospitalisations planned at the 
beginning of the trial will not be considered as SAE if they have been reported at the 
screening visit in the eCRF and performed as planned.
Changes in safety tests including blood pressure, pulse rate, electrocardiogram (ECG) and 
laboratory tests will be recorded as AEs, if they are not associated with an already reported 
AE, symptom or diagnosis, and:
!
action is required and taken with the investigational drug, i.e. dose reduction or treatment 
discontinuation,'
or
!
treatment due to the event is required (i.e. a concomitant medication is added or changed).
5.2.2
Worsening of pre-existing conditions
Expected fluctuations or expected deterioration of the underlying disease will not be recorded 
as an AE. If progressive disease occurs and is associated with symptoms, the signs and 
symptoms of progressive disease will be reported as an adverse event or a serious AE (if 
applicable).
Worsening of other pre-existing conditions will be recorded as an AE or SAE if one of the 
following criteria is met:
!
the criteria for an SAE apply,
!
action is required and taken with the investigational drug, i.e. dose reduction or treatment 
discontinuation,
!
treatment is required, i.e. concomitant medication is added or changed,
!
the investigator believes a patient has shown a clear, unexpected deterioration from the 
baseline condition.
Pre-existing conditions are not recorded as AEs if they do not meet at least one of the above 
criteria. Specifically, the following will not be recorded as an AE:
!
pre-existing conditions present at baseline, which remain unchanged during the trial,
!
expected fluctuations or expected deterioration of a pre-existing condition.
5.2.3
Dose limiting toxicity
Dose limiting toxicity (DLT) is defined as drug related CTCAE grade ≥ 3 non-
haematological toxicity (excluding: untreated nausea, untreated vomiting, CTCAE grade 3

untreated diarrhoea, CTCAE grade 3 "febrile neutropenia" and CTCAE grade 3 "infection 
with grade 3 or 4 neutrophils").
In patients with CRi or PR, persistent CTCAE grade 4 neutropenia or thrombocytopenia until 
three weeks after the end of the treatment cycle will be regarded a DLT unless the respective 
grade 4 cytopenia was pre-existent. In patients who required platelet substitution to maintain 
a CTCAE grade < 4 before treatment, a CTCAE grade 4 thrombocytopenia after treatment 
does not constitute a DLT.
5.2.4
Maximum tolerated dose
The MTD is defined as the highest dose at which six patients have been treated and less than 
two patients experienced DLT within the first cycle of treatment. The MTD will be defined 
based on safety data from the first cycle only. However, the data from later treatment cycles 
will be considered for future development of BI 6727 in this indication. To determine the 
MTD of BI 6727 on days 1 + 15 in combination with LDAra-C (schedule A), the dose 
escalation starting with 150 mg BI 6727 will be conducted following the “3 + 3 design with 
de-escalation” as described in section 4.1.3. To determine the MTD of BI 6727 on day 1 + 15 
monotherapy (schedule B), the dose escalation starting with the BI 6727 MTD determined in 
schedule A will be conducted following the “3 + 3 design with de-escalation” as described in 
section 4.1.3.
5.2.5
Laboratory investigations
Blood samples have to be collected at the time points specified in the flow chart. Safety 
laboratory examinations will include haematology, biochemistry and coagulation parameters. 
The following parameters will be determined at the time points specified in the flow-chart:
Haematology
haemoglobin, haematocrit, red blood cell count (RBC), 
white blood cell count (WBC) with differential, platelets.
Biochemistry
glucose, sodium, potassium, calcium, creatinine, aspartate 
amino transferase (AST), alanine amino transferase 
(ALT), alkaline phosphatase, lactate dehydrogenase, 
bilirubin, urea, total protein, uric acid, creatine 
phosphokinase (CPK) and Troponin.
Coagulation 
activated partial thromboplastin time (aPTT) and 
prothrombin time (PT); international normalised ratio 
(INR) where therapeutically indicated (i.e. vitamine K 
antagonist treatment)
Urine 
pH, glucose, erythrocytes, leukocytes, protein, nitrite will 
be analysed by dipstick (semiquantitative measurements; -
, +). In case of pathological findings, further evaluation 
should be performed and the findings documented.

After approval of Protocol Revision I, safety laboratory examinations should be done as 
medically indicated at discretion of the investigator. The results are not required to be entered 
in the eCRF; documentation in the source data is sufficient. Only in case of findings that are 
qualifying as an (S)AE, the respective (S)AE will be reported (eCRF and SAE form, if 
applicable).
5.2.6
Physical examination, height, weight, ECOG performance score
A general physical examination will be performed at screening and at the time points 
specified in the flow charts. Preferably, the same investigator should perform these 
examinations to enable comparability. Measurement of height (in cm) and body weight (in 
kg) and the evaluation of the ECOG performance score will be performed at the time points 
specified in the flow chart.
After approval of Protocol Revision I, physical examinations, weight, and ECOG 
performance score should be done as medically indicated at discretion of the investigator. 
The results are not required to be entered in the eCRF; documentation in the source data is 
sufficient.
5.2.7
ECG
12-lead resting ECG will be performed in all patients at the screening visit and at the EoT 
visit.
For patients in treatment schedules A and B ECGs will be recorded with every infusion of BI 
6727 (before the start and immediately before the end of the BI 6727 infusion), additional 
ECGs will be recorded in cycle 1. In cycle 1 at visit 1 and 4, and at visit 1 in cycle 2 the 
ECGs must be performed at the related PK sampling time points. All ECGs have to be 
digitally recorded using dedicated equipment provided by a contract research organisation 
(CRO; 
) at the following time points:
After approval of Protocol Revision I, ECGs should be recorded prior to and at the end of 
volasertib infusions. No digital and triplicate recording is required anymore. ECGs can be 
recorded with a local ECG machine.

The recording will be checked for pathological results (to be recorded as AEs) by the 
investigator. In addition, a centralized evaluation of all 12-lead ECGs recorded will be 
performed by a CRO (
).
After approval of Protocol Revision I, transmissions for central ECG analysis will be 
discontinued. 
In addition, ECGs should be done whenever the investigator deems necessary.
In case of drug related ECG changes, additional ECG monitoring will be performed in the 
respective and later cycles of treatment.
In case of QTcF > 470 ms prior to the planned start of infusion of BI 6727, the trial drug 
should not be administered.
In case of QTcF change from baseline > 60 ms with absolute QTcF < 500 ms (Grade 2
CTCAE V3.0) after receiving BI 6727, it is mandatory that patient remain at the investigative 
site after administration of BI 6727 for further ECG monitoring. The investigator will initiate 
further diagnostics (e.g. check electrolytes and check concomitant therapy that may be 
contributing to QTcF prolongation) and if required provide adequate treatment according to 
medical standards. The patient will be discharged from the investigative site after resolution 
of ECG findings. If the patient qualifies for a subsequent treatment course, depending on the 
benefit/risk ratio assessed by the investigator, the dose of BI 6727 will remain unchanged or 
reduced by 50 mg. For patients who will continue the BI 6727 treatment at the same dose 
level, in case of recurrence of the QTcF prolongation > 60 ms during the following cycles, it 
is mandatory that patient remains at the investigative site after administration of BI 6727 for 
continuous ECG monitoring. The patient will be discharged from the investigative site after 
resolution of ECG findings.
In case of QTcF prolongation to > 500 ms (Grade 3 CTCAE V3.0) after receiving BI 6727, it 
is mandatory that the patient remains at the investigative site after administration of BI 6727 
for further ECG monitoring. The patient will be discharged from the investigative site after 
resolution of ECG findings (e.g. when the QTcF value is < 470 ms on a single observation). 
The investigator will initiate further diagnostics (e.g. check electrolytes and check 
concomitant therapy that may be contributing to QTcF prolongation) and provide adequate 
treatment according to medical standards. If the patient qualifies for a subsequent treatment

course (see 4.1.4), the dose of BI 6727 will be reduced according to section 4.1.4. The first 
BI 6727 infusion subsequent to a cycle when BI 6727 related QTcF prolongation to > 500 ms 
was documented must be performed in an intensive care unit with a continuous ECG 
monitoring under the supervision of the intensive care unit physician; in case of recurrence of 
the QTcF prolongation > 500 ms at the reduced BI 6727 dose, the same procedures regarding 
patients monitoring as at previous occurrence will apply and the treatment with BI 6727 will 
be permanently discontinued (see 4.1.4).
In case of occurrence of symptoms suggestive of arrhythmia related to QTcF prolongation, 
patient will be hospitalized, a cardiologic evaluation will be performed and treatment 
provided according to medical standards.
In case of occurrence of symptoms of left ventricular insufficiency, a cardiologic evaluation 
by a cardiologist and an echocardiogram must be performed.
5.2.8
Vital signs
Vital signs (blood pressure and pulse rate after two minutes supine rest) will be recorded at 
every visit, and during BI 6727 application at the following time points: pre-infusion, and at 
minutes 30 (%5), 60 (%10) and 120 (%10) after start of infusion.
After approval of Protocol Revision I, vital signs should be measured as medically indicated 
at discretion of the investigator. The results are not required to be entered in the eCRF; 
documentation in the source data is sufficient. Only in case of findings that are qualifying as
an (S)AE, the respective (S)AE will be reported (eCRF and SAE form, if applicable).
5.3
OTHER
5.3.1
Demographics and history
Demographics (sex, birth date, race) and baseline conditions will be collected during the 
screening visit.
The WHO classification of the disease, the date of first cytological diagnosis (month and 
year) and cytogenetics of AML will be reported in the eCRF. In patients with 
relapsed/refractory AML (included only in the phase I part of the trial) the patient’s history of 
AML will also be obtained. Previous malignant disease will be reported. Previous chemo-, 
immuno-, or hormone-therapy administered for malignant disease will be reported. If 
applicable, the total radiation dose and radiation field of any previous radiotherapy will be 
recorded. 
5.3.2
Concomitant therapies and diagnoses
Concomitant diagnoses and / or therapies present at trial entry and / or during screening and 
relevant to the patient’s safety during the trial as judged by the investigator, will be recorded 
in the eCRF.

5.3.3
Assessment of ineligibility for intensive treatment
A patient's ineligibility for intensive treatment is assessed by the investigator in agreement 
with the patient, based on a comprehensive documentation of the reasons for this assessment. 
This documentation will include the patient age, medical history, performance score, organ 
dysfunctions, co-morbidities, patients informed decision, and other relevant factors, 
supplemented with the investigators assessment what gave reason for evaluating the patient
ineligible for intensive treatment.
5.3.4
Cytogenetics and molecular genetics
For central analysis of cytogenetics (chromosomal banding) and investigation of molecular 
genetic aberrations (mutations or deregulated expression of genes NPM1, CEBPA, FLT3 and
optionally WT1, AML1, RAS, MLL, TP53, KIT, TET2, IDH1, EVI1, ERG, MN1; BAALC) 
a 5-10 mL bone marrow sample and a 40 mL blood sample will be collected at the screening 
visit. The samples will be sent via courier to the specialised laboratory for the aforementioned 
analysis. The samples should arrive in the lab within 24 hours after sample collection.
Detailed instructions for cytogenetic sampling, handling and shipment of samples are 
provided in the ISF.
5.3.5
Pharmacogenetics
Pharmacogenetics investigates genetic variations in patients to explain and to predict their 
individual response to drugs. 
To allow pharmacogenetic analyses, all patients will be asked for one blood sample. The 
sample will be taken and processed or stored after separate informed consent is given in 
accordance with local ethical and regulatory requirements. 
The sample (max. 10 mL blood) will be completely anonymised. The anonymisation 
procedure will guarantee a very high level of data protection for the donor. Once the 
anonymisation has been carried out, there will be no legal way to trace back to the identity of 
the donor. The anonymised DNA may be analysed at a later time to identify whether there are 
genetic factors that could contribute to a better therapeutic outcome or a higher risk of 
developing treatment-related adverse drug reactions. These analyses may include genes 
related to efficacy, safety and pharmacokinetics. 
After anonymisation, the sample (or the DNA derived thereof) will be stored at Boehringer 
Ingelheim for at least 10 years after the end of the clinical trial or until there is no more 
material available for tests.
Participation in the pharmacogenetics part is voluntary and not a prerequisite for participation 
in the study.
5.3.5.1
Methods and timing of sample collection
The blood sample for pharmacogenetic testing will be taken at the screening visit . A 
maximum of nine (9) mL of blood will be collected per EDTA blood sampling tube for those

patients who signed a separate informed consent concerning genotyping. The blood samples 
will be stored at a temperature of at least -20&C. Once frozen, thawing of the samples should 
be avoided.  Detailed instructions for pharmacogenetic sampling, handling and shipment of 
samples are provided in the ISF.
All samples will be shipped to the logistic CRO.
5.4
APPROPRIATENESS OF MEASUREMENTS
Determination of MTD is based on toxicities graded according to CTCAE. The CTCAE
criteria are commonly used in the assessment of adverse events in cancer patients.
The criteria to be used for evaluation of response are well established and scientifically 
accepted.
5.5
DRUG CONCENTRATION MEASUREMENTS - PHARMACOKINETICS
Blood will be collected at specified time points during the first treatment cycle of each 
treatment schedule (see appendix 10.1) to determine the plasma concentration of BI 6727 and 
cytarabine. Further exploratory analysis for identification of drug metabolites could be done 
if applicable. If these additional analyses are performed, the results will be reported 
separately. The actual sampling date and time for blood samples will be documented in the 
eCRF. These actual sampling times will be used for determination of pharmacokinetic 
parameters. Also, for a valid PK analysis, it is of utmost importance to document the exact 
clock time of trial medication administration. The duration of the BI 6727 infusion (planned 
1 hours) will be documented (start and end time of the infusion) in the eCRF. Every attempt 
will be made to adhere to an infusion time of 1 hours for BI 6727 with a constant infusion 
rate.
5.5.1
Methods and timing of sample collection
5.5.1.1
Plasma sampling for pharmacokinetics
For pharmacokinetic purposes the following blood volumes will be taken per subject during 
the initial treatment cycle:
In treatment schedule A, a total amount of around 90 mL blood will be taken per subject. In 
treatment schedule B around 54 mL blood and in treatment schedule C around 35 mL blood 
will be taken per subject in the first cycle. In cycle 2, about 16 or 6 mL of blood will be 
drawn for pharmacokinetic purposes in treatment schedule A or B, respectively. The samples 
have to be taken from the opposite arm, not from the infusion arm. For patients having central 
venous access, BI 6727 may be administered using this device and PK samples obtained from 
either forearm.
For quantification of BI 6727 plasma concentrations, around 3 mL of venous blood will be 
taken in an EDTA (ethylendiaminetetraacetic acid)-anticoagulant blood drawing tube (e.g. 
 at the time points specified in the flow charts and in appendix 
10.1. The sampling tube has to be mixed immediately with the anticoagulant by gently 
inverting about 10 times. Vigorous shaking should be avoided to prevent haemolysis.

The whole blood is to be centrifuged immediately at 4-25°C at approximately 3000 rpm 
(~2100 g) for at least 15 minutes. Please store the PK samples in an ice bath (up to 30 
minutes) until centrifugation if they cannot be centrifuged immediately. 
Transfer immediately two aliquots of EDTA plasma (at least 500 μL each) into carefully and 
unique labelled cryovials. Please check the patient number and planned sampling time. The 
visit, the exact time (hh:mm, 24 h-clock time) and date (month in letter) of sampling are to be 
recorded in the eCRF. 
The plasma samples have to be stored at -20°C or below at the clinical site until shipment on 
dry ice to the logistic CRO. 
They also will be stored at the analytical laboratory at -20°C or below until analysis.
Detailed handling instructions for plasma samples are provided in the ISF.
For quantification of cytarabine plasma concentrations, around 5 mL of venous blood will be 
taken in a lithium heparin -anticoagulant blood drawing tube (e.g. Vacutainer® or 
Monovette) at the time points specified in the flow charts and in appendix 10.1. THU 
(tetrahydrouridine) will be added immediately to the sampling tube in order to prevent 
catabolism of cytarabine. The sampling tube has to be mixed with the anticoagulant by gently 
inverting about 10 times. Vigorous shaking should be avoided to prevent haemolysis.
The whole blood is to be centrifuged at 4-25°C at approximately 3000 rpm (~2100 g) for at 
least 15 minutes. Please store the PK samples in an ice bath (up to 30 minutes) until 
centrifugation if they can’t be centrifuged immediately. 
Transfer immediately two aliquots of heparinized plasma (at least 600 μL each) into carefully 
and unique labelled cryovials. Please check the patient number and planned sampling time. 
The visit, the exact time (hh:mm, 24 h-clock time) and date (month in letter) of sampling are 
to be recorded in the CRF. 
The plasma samples have to be stored at -20°C or below at the clinical site until shipment on 
dry ice to the logistic CRO. 
They also will be stored at the analytical laboratory at -20°C or below until analysis.
Detailed handling instructions for plasma samples are provided in the ISF.

BIOMARKER - PHARMACODYNAMIC SAMPLING
5.6.1
Methods and timing of sample collection
For direct analysis of effects of BI 6727 and/or cytarabine on the leukaemia cells, bone 
marrow aspirate samples (or peripheral blood if no bone marrow can be obtained, e.g. punctio 
sicca) will be collected at screening (all treatment schedules), at visit 2, i.e. 5±1 days after the 
end of the first BI 6727 infusion (treatment schedules A and B only), and on day 28 in the 
first cycle only (all treatment schedules). A total of about 5 mL of bone marrow aspirate from 
each patient (or 5 mL of peripheral blood if no bone marrow can be obtained) will be 
required for the pharmacodynamic analysis. The sampling of bone marrow will be performed 
according to standard procedure and only by experienced persons of the respective trial site. 
Bone marrow aspirate and peripheral blood from samples taken for screening and for 
response assessment at the end of the first treatment cycle will be used for comparison.
5.7
PHARMACOKINETIC - PHARMACODYNAMIC RELATIONSHIP
If the data suggest a pharmacokinetic / pharmacodynamic relationship of special parameters 
(e.g. neutrophil count), a detailed analysis may be performed.
5.8
DATA QUALITY ASSURANCE
The trial will be conducted in compliance with the protocol, the principles laid down in the 
Declaration of Helsinki version 1996 (please, refer to section 8), local law and according to 
the principles of GCP and the company standard operating procedures (SOPs). An 
investigator meeting will be performed prior to start of the trial to inform all investigators 
about the trial drugs and the procedures of the trial. Instead, each investigator could also be 
visited individually by the clinical monitor and the clinical research associate (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 8.2.4.
An audit may be performed if required or if Boehringer Ingelheim would decide to perform 
an audit.
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 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.

6.2.3.2
Follow-up visit
Follow-up visits will be performed after the EoT visit in case patients are not eligible for 
further treatment cycles until death, lost to follow-up or agreement between sponsor and 
coordinating investigator not to pursue further follow up visits. Follow-up visits should be 
performed at 12 weeks intervals or earlier if appropriate. Follow-up visits may also be

6.2.3.3
End of the whole trial
The clinical trial will be analyzed and reported after all patients enrolled in the phase II part 
have either stopped treatment or have been treated for at least four months (i.e. are expected 
to have received at least four treatment cycles). The timepoint for the report is chosen, 
because no major changes in the readout of the primary endpoint of phase II (response rate) 
are expected after patients have received ≥4 cycles. If patients are still ongoing in the trial or 
phase I schedule B is not yet completed at the time of the report, the clinical trial database 
will be kept open to collect additional data that will be reported in a revised report. If patients 
are still ongoing on treatment ~2 years after randomization of the last patient in phase II a 
revised clinical trial report might be generated with the clinical trial database still kept open 
to collect additional data. The trial will be completed as soon as the last patient has completed 
his / her last visit. The final results will be reported in a revised report.
In case the trial is ended by the sponsor when patients are still being treated with a clinical 
benefit from BI 6727, the patients will be offered to be treated in a follow-up trial which will 
be set up and allow patients to receive therapy with BI 6727.
6.3
REMOVAL OF PATIENTS FROM THERAPY OR ASSESSMENT
A patient has to be withdrawn from the trial in case one of the following criteria applies:
!
A patient withdraws consent (patients are free to discontinue their participation in this
trial at any time without the need to justify this decision).
!
A treatment cycle has been delayed for more than three weeks for other than medical
reasons
!
A patient is no longer able to participate in the trial (e.g. AEs unrelated to therapy or
disease progression, surgery, concomitant diagnoses, concomitant therapies 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 is being administered forbidden concomitant medication (refer to section 4.2.2)

A patient can be withdrawn after discussion between the sponsor and the investigator 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 patient is withdrawn from the trial, the
next scheduled visit and the EoT have to be performed if feasible. Every effort should be 
made to follow-up patients in case an AE is still ongoing at the time of withdrawal. Patients 
who withdraw after assignment / randomisation and prior to the first treatment will not be
included in the analysis data set for efficacy evaluation. They will be entered into the trial 
database, the reason for withdrawal will be documented and reported descriptively as well as 
by patient listing in the final trial report.
A patient has to discontinue trial drug administration in case
!
DLT occurs which does not recover to a degree that allows treatment continuation or a 
second episode of DLT occurs in this patient or
!
PD develops, including deterioration of general condition due to disease progression
Patients included in the phase I part who have not completed at least one cycle will be 
replaced unless they discontinued the trial due to drug-related AEs.
Patients allocated to treatment schedules A or B in the phase I part of the trial who for 
administrative reasons omitted the second infusion in the first 4-week cycle and were unable 
to receive the missed infusion within the next two days will be replaced.
Patients allocated to treatment schedules A in the phase I part of the trial who for 
administrative reasons omitted more than two doses of cytarabine in the first 4-week cycle
will be replaced.
None of the patients randomized in the phase II part of the trial will be replaced for any 
reason.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
The trial will be performed in two parts, a phase I part and a phase IIa part. In the phase I part 
of the trial, BI 6727 will be investigated as monotherapy and in combination with LD-Ara-C 
in patients with relapsed/refractory AML. In the phase I part, the dose of BI 6727 will be 
escalated to determine the maximum tolerated dose (MTD) of BI 6727 monotherapy and
BI 6727 in combination with LD-Ara-C in relapsed/refractory AML patients who are 
ineligible for other treatment options. 
In the phase IIa part, the combination of BI 6727 at MTD with LD-Ara-C and LD-Ara-C 
monotherapy will be investigated to determine the efficacy of the combination schedule in 
comparison to LD-Ara-C monotherapy in previously untreated AML patients that are 
considered ineligible for intensive treatment.
7.1
STATISTICAL DESIGN - MODEL
The trial will be performed as an open label study. In phase I patients will not be randomized; 
they will be assigned to the treatment schedule that is being filled at the time the patient is 
ready to enter the trial (BI 6727 monotherapy and BI 6727 in combination with LD-Ara-C, 
respectively). In phase IIa patients will be randomly allocated to one of the two different 
treatment schedules BI 6727 in combination with LD-Ara-C and to a monotherapy schedule
with LD-Ara-C only, respectively.
To determine the MTDs in the phase I part, cohorts of patients will be entered sequentially 
into escalating dose tiers using the 3+3 design with dose de-escalation (R04-0569) (see 
section 4.1.3). Intra-individual dose escalation will be allowed according to the rules 
specified in section 4.1.4.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The analyses will thoroughly explore all aspects of the efficacy and safety of BI 6727 in 
combination with LD-Ara-C. All analyses in this study are descriptive and exploratory by 
nature. Any statistical tests are performed only to provide a statistical framework from which 
to view the results and providing aid for planning further studies. No formal statistical tests 
are foreseen.
7.3
PLANNED ANALYSES
Two analysis populations are defined for efficacy and safety analyses. For the phase I part the 
full analysis set (phase I) is defined, in analogy to the intention to treat population as the 
treated set with respect to phase I; i.e. all patients of phase I who have received at least one 
single dose of BI 6727 will be considered, including the patients who have been replaced for 
any reason (see section 6.3).

For the phase II part the full analysis set (phase II) is defined, in analogy to the intention to 
treat population as the treated set with respect to phase II; i.e. all patients of phase II who 
have received at least one single dose of either BI 6727 or cytarabine will be considered,
No per protocol population will be used for analyses. However protocol violations will be 
described.
7.3.1
Primary analyses
7.3.1.1
Assessment of the MTD and derived variables for first cycle only
One primary objective for this study is the tolerability and safety of BI 6727 as monotherapy 
and in combination with cytarabine, respectively, as reflected by the MTD (for definition of 
MTD please refer to 5.2.4). 
In addition, to determine the MTD, an analysis on conditional probabilities for a DLT given 
the dose will be done, based on the logistic regression model.
For the analysis of the tolerability and safety, please refer to section 7.3.3.
7.3.1.2
Assessment of the primary efficacy endpoint and derived variables
The primary endpoint for efficacy is best objective response derived from the data of all 
cycles. The primary analysis will be done for all patients of the full analysis set (phase II) for 
all treatment schedules separately. Each patient will be assigned to one of the response 
categories described in section 5.1.1.1.
Each patient’s best response will be used as a primary measure. To describe response over 
time, the proportions of patients in each response category will be tabulated at specified time 
intervals.
The number of patients with objective response (best response is CR or CRi) will be 
summarised. Patients will be followed up for assessment of response and progression until 
they progress, receive any other anti-leukaemia 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.
7.3.1.3
Statistical group comparison
All statistical group comparisons will be performed with respect to the full analysis set (phase 
II)
The comparison of the treatment schedule to the control schedule will be based on the 
conditional power approach and on a stopping for futility check. The conditional power for 
showing superiority of a treatment schedule with respect to the control schedule at a later 
time point will be evaluated. The conditional power will be compared to a given fixed value 
that is based on assumptions for the information time and for the significance level of the 
(hypothetical) statistical test at a later time point (see also section 7.6.2).

Odds ratios, confidence intervals, and Fisher’s exact test will be used to compare treatments 
in an exploratory manner if appropriate. Additionally, the conditional power for showing 
superiority at a later time point will be evaluated. The exploratory nature of these analyses 
will be considered when interpreting the significance levels. P-values derived from statistical 
tests smaller than 5% will only be reported as nominally significant regarding the small 
sample size in each treatment schedule.
7.3.2
Secondary analyses
7.3.2.1
Assessment of the secondary endpoints and derived variables
Secondary endpoints related to efficacy will be event free survival, overall survival, relapse-
free survival, and remission duration.
Event free survival, overall survival, relapse-free survival
Event free survival (EFS) is defined as the duration of time from randomisation to time of 
treatment failure (i.e. PD), relapse from CR, or death from any cause, whichever comes first. 
Overall survival is the time from randomisation until death. Relapse-free survival is defined 
only for patients who achieve CR and is measured from the date of attaining CR until the date 
of recurrence or death from any cause, whichever occurs first.
In case there is no occurrence of death or treatment failures 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.
The causes of death will be summarised, along with whether death was plausibly related to 
disease progression.
Remission duration, response rate at different time points
Exploratory analyses will be performed to determine the remission duration and the response 
rate after specified time intervals. Analysis of remission duration will only be done for 
patients who achieve CR.
7.3.3
Safety analyses
The occurrence of dose limiting toxicity (DLT) as well as the incidence and intensity of 
adverse events graded according to CTCAE, laboratory parameters, vital signs and duration 
of neutropenia will be evaluated.
All patients of the full analysis set (both phase I and phase II) will be included in the safety 
analyses. 
Two analyses will be performed. The first analysis of safety will be performed for the first 
part of the trial (determination of the MTD, first cycle only, treatment regime=initial dose at 
the start of the treatment, full analysis set (phase I only)). This descriptive analysis will 
evaluate the MTD for each treatment schedule. The second analysis will be performed with

respect to all cycles and will act as a support for the determination of the MTD (full analysis 
set (both phase I and phase II)).
Incidence and intensity of adverse events
The severity, and timing of adverse events will indicate how well the treatment regimen is 
tolerated. Toxicities will be evaluated using the CTCAE grading scheme. 
The overall incidence and intensity of adverse events, as well as relatedness of adverse events 
to treatment with BI 6727 monotherapy and in combination with cytarabine, respectively,
will be reported for all treatment schedules.
Serious adverse events will be tabulated. In addition, events leading to dose reduction or 
treatment discontinuation will be examined, but may not be reported as individual tables, 
depending upon the extent of overlap with the occurrence of DLT.
Descriptive statistics will be used to describe changes in laboratory tests over time. In 
addition, all abnormalities of potential clinical relevance will be reported.
Events that started within the period starting with first administration of the trial drug and 
ending six weeks after the first treatment administration in the last treatment cycle will be 
considered as having occurred during treatment. In general, later events will be attributed to 
the post-study period and will be presented separately. However, post-study events will be 
examined to determine whether they need to be combined with on-treatment events in an 
additional table.
ECG measurements
Prolonguation of QT/QTc times will be analysed descriptively and exploratory based on the 
ECG measurements described in Section 5.2.7. Further details of the analysis of ECG data
will be specified in the statistical analysis plan.
7.3.4
Interim analyses
Early analyses of response to therapy will be performed before completion of recruitment in 
order to support internal strategic decision making and planning for future clinical trials. In 
order to avoid bias of these early efficacy analyses on trial conduct, the results will not be 
distributed to trial sites before database lock for the CTR (see section 6.2.3.3). The analyses 
will be performed when approximately 50% of planned patients in the phase II part of the 
trial have either stopped treatment or completed at least two treatment cycles. Details of the 
early analyses of response to therapy will be specified in the interim trial statistical analysis 
plan. The early efficacy analyses will be documented and archived. If considered necessary 
for internal strategic decision making the early efficacy analysis may be repeated once when 
approximately 70% of planned patients in the phase II part of the trial have either stopped 
treatment or completed at least two treatment cycles.
After all patients of treatment schedule A that are contained in the full analysis set (phase I) 
have either completed at least one course of BI 6727 in combination with cytarabine or

dropped out of the study, a safety analysis will be performed. For this purpose a database 
snapshot will be performed. The safety analysis will summarize results regarding safety of 
the patients in the phase I part and will contain the determination of the MTD as well as a 
recommendation for the dose of BI 6727 to be used in the phase II part of the study. The 
selection of the recommended dose for the phase II part will consider overall safety observed 
during all treatment cycles. No efficacy comparisons will be performed in this phase I safety 
analysis. Detailed specifications of the phase I safety analysis are provided in the TSAP. The 
phase I safety analysis will be documented and archived.
For other safety purposes database snapshots can be performed as deemed appropriate.
7.3.5
Pharmacokinetic methods
7.3.5.1
Pharmacokinetic analyses
The following basic pharmacokinetic parameters will be calculated in cycle 1 for BI 6727 in 
plasma for schedules A and B on visits 1 and 4 and for cytarabine in plasma for schedule C 
on visits 1 and 3 (refer to section 10.1). 
Additional parameters may be determined if deemed necessary:
−
Cmax (maximum measured concentration of BI 6727 or cytarabine in plasma)
−
tmax (time from dosing to maximum measured concentration)
−
AUC0-∞ (area under the concentration-time curve of BI 6727 or cytarabine in 
plasma over the time interval from 0 extrapolated to infinity)
−
AUC0-24 (area under the concentration-time curve of BI 6727 or cytarabine in 
plasma over the time interval from 0 to 24)
−
t1/2 (terminal half-life of BI 6727 or cytarabine in plasma)
−
MRT (mean residence time of BI 6727 or cytarabine in the body after intravenous
or subcutaneous administration, respectively)
−
CL (total clearance of BI 6727 in plasma after intravascular administration)
−
CL/F (total clearance of cytarabine in plasma after subcutaneous administration)
−
Vz (apparent volume of distribution during the terminal phase λz following a 
intravascular dose of BI 6727)
−
Vz /F (apparent volume of distribution during the terminal phase λz following a 
subcutaneous dose of cytarabine)
−
Vss (apparent volume of distribution at steady state following intravascular
administration of BI 6727)

Pharmacokinetic parameters after first and second administration will be compared in a
descriptive manner.
The pharmacokinetic parameters Cmax, AUC0-∞ and AUC0-24 will be explored with respect to
dose proportionality (if more than 2 doses are investigated).
All evaluable patients will be included in the pharmacokinetic analysis. A patient is 
considered to be not evaluable if the subject has an important protocol violation relevant to 
the evaluation of pharmacokinetics or has insufficient data. Patients who are considered as 
not evaluable will be listed with their individual plasma concentrations and individual 
pharmacokinetic parameters, however, will not be included in descriptive statistics for plasma 
concentrations, pharmacokinetic parameter evaluation or other statistical assessment.
The following descriptive statistics will be calculated for BI 6727 and cytarabine 
concentrations as well as for all pharmacokinetic parameters: N, arithmetic mean, standard 
deviation, minimum, median, maximum, arithmetic coefficient of variation, geometric mean, 
geometric coefficient of variation. Descriptive statistics of concentrations at specific time 
points will be calculated only when at least 2/3 of the individuals have concentrations within 
the validated concentration range. The overall sample size to decide whether the “2/3 rule” is 
fulfilled will be based on the total number of samples intended to be drawn for that time 
point. Descriptive statistics of parameters will be calculated only when at least 2/3 of the 
individuals have parameters. The overall sample size to decide whether the “2/3 rule” is 
fulfilled will be based on the total number of patients included in the analysis of the 
parameter.
Pharmacokinetic parameters of cytarabine dosed along with BI 6727 will be compared in a 
descriptive manner to those of cytarabine dosed alone to assess the effect of BI 6727 on 
cytarabine pharmacokinetics. Similarly, pharmacokinetic parameters of BI 6727 obtained in 
treatment schedule A will be compared to the parameters obtained in treatment schedule B to 
assess the effect of cytarabine on BI 6727 pharmacokinetics. 
Refer to Appendix 10.1 for details concerning derivation of pharmacokinetic parameters.
7.3.5.2
Pharmacogenetic analyses
Pharmacogenetic analyses will be carried out using an explorative approach on anonymised 
samples, if they are deemed helpful to interpret the pharmacokinetics, efficacy, and safety 
data of BI 6727.
7.4
HANDLING OF MISSING DATA
Every effort will be made to obtain complete information on all AEs, with particular 
emphasis on potential dose limiting toxicities.
If not stated otherwise, missing data will not be imputed and remain missing. Potential
outliers will be reported and analysed as observed.

The occurrence of missing data should be minimised 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.
Laboratory value: Missing baseline laboratory values will be imputed by respective values
from the screening visit.
Pharmacokinetic parameters
Concentration data identified with NOS (no sample), NOR (no valid result), NOA (not
analyzed), BLQ (below the limit of quantification), and NOP (no peak detectable) will be
ignored and not replaced by zero at any time point (applies also to the lag phase). Descriptive
statistics of concentrations at specific time points will be calculated only when at least 2/3 of
the individuals have concentrations within the validated concentration range. The overall
sample size to decide whether the “2/3 rule” is fulfilled will be based on the total number of
samples intended to be drawn for that time point (i.e. BLQ, NOR, NOS, NOA, NOP are
included).
In the noncompartmental analysis, concentration data identified with NOS, NOR, and NOA
will not be considered. BLQ and NOP values in the lag phase will be set to zero. The lag
phase is defined as the period between time zero and the first time point with a concentration
above the quantification limit. All other BLQ/NOP values of the profile will be ignored.
If the predose concentration is less than or equal to 5 percent of Cmax value in that subject, the
subject’s data without any adjustments can be included in all pharmacokinetic measurements
and calculations (i.e. the predose value will not be changed to zero). If the predose value is
greater than 5 percent of Cmax, the subject should be dropped from all statistical evaluations.
The individual pharmacokinetic parameters can be calculated and listed separately.
Every effort will be made to include all concentration data in an analysis. If not possible, a
case to case decision is required whether the value should only be excluded from half-life
estimation or the complete analysis.
-
If a concentration is only excluded from half-life determination, it will be used for 
all other calculations (e.g. descriptive statistics) and for graphical presentation
-
If a concentration value is excluded from all calculations, it will not be presented
graphically or used for the calculation of descriptive statistics and parameter 
determination. However, the excluded concentration itself will be listed in the 
tables in section 15 of the clinical trial report associated with an appropriate flag.
Descriptive statistics of parameters are calculated only when at least 2/3 of the individual
parameter estimates of a certain parameter are available. If the actual sampling time will not
be recorded or will be missing for a certain time point, the planned time will generally be
used for this time point instead. Pharmacokinetic parameters which cannot be determined will
be identified by "not calculated" (NC).

7.5
RANDOMISATION
In the phase I part of the trial patients will be assigned, not randomized, into escalating 
dosage groups by order of admission into the trial. 
Randomisation will be performed in the phase IIa part of this trial. In phase IIa, equal 
numbers of patients will be randomised to the respective treatment schedules. The medical 
data service will provide randomisation envelopes that are generated using a validated 
system. 
An eligible patient is reported by fax to the clinical monitor at Boehringer Ingelheim; in 
phase I the patient will be assigned to the treatment schedule (according to 4.1.2), in the 
phase IIa part the clinical monitor will open the next randomisation envelope in the 
predetermined order. The result of the assignment / randomisation along with the appropriate 
starting dose (in phase I part) will be communicated to the investigator by the clinical 
monitor (for more information please refer to section 4.1.2 and the ISF).
7.6
DETERMINATION OF SAMPLE SIZE
7.6.1
Determination of the maximum tolerated dose
In oncology trials, the “standard design” is a rule-based up-and-down scheme using cohorts
of three patients (e.g. 3+3 design, or the modified Fibonacci dose escalation, see Edler and
Burkholder in Crowley (R07-0220)). The operating characteristics of the standard design are
discussed in different papers and are summarized by Storer in Crowley (R07-0220). The
standard design and all other designs, that approach the MTD from below, will tend to yield a
low estimate of the MTD. In addition, it is “robust”, that means that the design will determine
a reasonable MTD and that escalation will be sensible, given the observed DLTs (see Potter
R07-0223).
Table 7.6: 1 shows the probabilities of two or more out of six patients to be observed with 
DLT for some assumed probabilities of experiencing DLT in a certain dose group. There will 
be a probability of at least 80 % for two or more patients to exhibit DLT, if the underlying 
individual probability for a patient in that dose group to reach DLT is 42 % or larger.

Thus, the determined MTD is defined as the highest dose of the treatment drug (BI 6727 for 
the two different schedules) at which no more than one out of six patients experience DLT in 
the first cycle.
For the planned sample size it is assumed that 5 different dosage groups are needed per 
treatment schedule with 2 additional dosage tiers of 3 patients (3+3 design). It is assumed that 
the average number of patients in a dosage group as well as in a dosage tier will be 3 
(including replacement patients).
Altogether this leads to an estimated sample size of 21 patients per treatment schedule. Note 
that this calculation does so far not include any additional patients to be included at the 
presumptive MTD. Naturally, the calculated sample size of 21 patients per treatment schedule
represents only a rough estimation since the number of patients needed is induced by the 3+3 
design and is subject to different influencing factors.
7.6.2
Calculation of phase II sample size based on stopping for futility
Sample size calculation for phase II of this trial are based on the comparison between the 
treatment schedules (BI 6727 combined with cytarabine) and the control schedule (cytarabine 
mono therapy)
The calculation of the phase II sample size is based on a stopping for futility approach (R07-
2799, R07-2798). The calculated sample size is based on the assumption that the actual phase 
II trial represents an interim analysis of a (hypothetical) phase III trial that tests on stopping 
for futility. The test decision (with respect to phase II) is made by looking at the conditional 
p-value obtained at the time of interim analysis and comparing it to a given fixed value, the 
critical p-value. Obviously, in this setting, the critical p-value equals the type I error 
probability. A characteristic that can be derived from the critical p-value is the conditional 
power. It provides quantitative information about the probability that a treatment schedule
will show superiority compared to a control schedule subject to the response information 
available at interim analysis.
It is assumed that the response rate of the mono treatment schedule (control schedule) is 
given as 15%, whereas the response rate of a combination therapy is 30%. The overall type I 
error is chosen as 5% (one-sided), the overall power as 65%, and the information fraction 
(number of patients at interim analysis divided by total number of patients) as 60%. 
Altogether this leads to a sample size of 86 patients for the interim analysis, i.e. 43 per 
treatment schedule. With respect to the (hypothetic) interim analysis, which is the actual 
phase II comparison, a power of 78.3% and a type I error (the critical p-value) of 18.9% is 
achieved with a critical conditional power value of 23.6% (under the current trend 
hypothesis, see R07-2799; all calculations performed with EAST 5).
In summary, this means that with a total sample size of 86 patients (43 patients per treatment 
schedule) a power of 78.3% can be achieved with a type I error of 18.9 % and a critical
conditional power of 23.6%.

If the response rate of the combination therapy is assumed to be 25 % instead of 30 % the 
calculated sample size, leading to the identical power values and error probabilities as above, 
rises to 174 patients (87 per treatment schedule).

ADMINISTRATIVE MATTERS
The trial will be carried out in compliance with the protocol, the principles laid down in the 
Declaration of Helsinki, version as of October 1996 (as long as local laws do not require to 
follow other versions), in accordance with the ICH Harmonised Tripartite Guideline for Good 
Clinical Practice (GCP) and relevant BI SOPs. Standard medical care (prophylactic, 
diagnostic and therapeutic procedures) remains in the responsibility of the treating physician 
of the patient.
Insurance Cover: The terms and conditions of the insurance cover are made available to the 
investigator and the patients via documentation in the ISF (Investigator Site File).
8.1
ETHICS
8.1.1
Independent Ethics Committee or Institutional Review Board
The trial will not be initiated before the protocol and informed consent and patient
information form have been reviewed and received approval / favourable opinion from the 
local Independent Ethics Committee (IEC) and approval by the Competent Authority (CA), 
as required by local laws and regulations. Should a CTP amendment be made that needs IRB 
/ IEC approval and authority notification/approval, the changes in the CTP will not be 
instituted until the amendment and revised informed consent (if appropriate) have been 
reviewed and received approval / favourable opinion from the local IEC and the CA, as 
required by local laws and regulations. A CTP amendment intended to eliminate an apparent 
immediate hazard to patients may be implemented immediately providing that the regulatory 
authority and IRB / IEC are notified as soon as possible and an approval is requested. CTP 
amendments exclusively for logistical or administrative changes may be implemented with 
notification to the IEC and CA only.
The constitution of the IEC must meet the requirements of ICH GCP and of the participating 
country / countries. A list of the IEC members who attended the meeting when the CTP / 
CTP amendment was discussed, including names and qualifications, needs to be provided by 
the IEC to the sponsor. The sponsor must provide to the regulatory authorities the name and 
address of the IEC along with a statement from the IEC that it is organised according to GCP 
and the applicable laws and regulations. The IEC must perform all duties outlined by the 
requirements of ICH GCP and of the participating country / countries. 
8.1.2
Patient Information and Informed Consent
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 authorised 
monitors (CML/CRA) or Clinical Quality Assurance auditors appointed by Boehringer 
Ingelheim, by appropriate IEC members, and by inspectors from regulatory authorities.  
Should a CTP amendment become necessary, the patient consent form and patient
information form may need to be revised to reflect the changes to the CTP. It is the 
responsibility of the sponsor to ensure that an amended consent form is reviewed and has 
received approval / favourable opinion from the IEC and CA, as required by ICH GCP and 
by local laws and regulations, and that it is signed by all patients subsequently entered in the 
trial and those currently in the trial, if affected by the amendment.
8.2
RECORDS
8.2.1
Drug accountability
Drug supplies, which will be provided by the sponsor and a CRO appointed by the sponsor, 
must be kept in a secure, limited access storage area under the storage conditions defined by 
the sponsor. Where necessary, a temperature log must be maintained to make certain that the 
drug supplies are stored at the correct temperature.
The investigator or pharmacist or her/his delegate must maintain records of the product’s 
delivery to the trial site, the inventory at the site, the use by each patient, and the return to the 
sponsor or alternative disposition of unused product(s). 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 or pharmacist 
will maintain records that document adequately that the patients were provided the doses 
specified by the CTP and reconcile all investigational products received from the sponsor. At 
the time of return to the sponsor or the appointed CRO, the investigator or pharmacist 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 investigator’s possession.
8.2.2
Emergency code break
Not applicable.
8.2.3
Case Report Forms (CRFs)
All of the clinical data will be captured via electronic data capture (EDC) using athe Oracle 
Clinical Remote Data Capture system, a web-based tool. The investigator site staff will enter 
and edit the data via a secure network, with secure access features (username, password and 
secure identification or username and password – an electronic password system). A 
complete electronic audit trail will be maintained.  The investigator will approve the data
using an electronic signature (Ref: 21 CFR Part 11), and this approval is used to confirm the 
accuracy of the data recorded.

Electronic CRFs (eCRFs) will be used for all patients. The investigator’s data will be 
accessible from the investigator’s site throughout the trial. Relevant medical history prior to 
enrolment will be documented at the baseline visit. Thereafter during the trial, narrative 
statements relative to the patient’s progress during the trial will be maintained. The electronic 
CRFs must be kept current to reflect patient status at each phase during the course of the trial. 
The patients must not be identified on the electronic CRF by name. Appropriate coded 
identification (i.e. Patient Number) must be used. The investigator must make a separate 
confidential record of these details (patient identification code list) to permit identification of 
all patients enrolled in a clinical trial in case follow-up is required. While a trial is ongoing 
and until the access to the database has been terminated, there will be no Documentation of 
Changes (DOCs). All changes will be requested from the investigator through the EDC 
system. If a change is necessary once the investigator has no further access to the database, a 
DOC will be sent to the investigator for confirmation of the change. The investigator’s 
signature is requested to show he/she agrees with the change that was made. The original 
DOC is kept by the investigator.
Copies of the electronic CRF together with all data changes made will be supplied to the 
investigator at the end of the trial. The investigator will be responsible for retaining all 
records pertaining to the trial as specified in the appropriate contract.
8.2.4
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 reported on the CRFs or 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.
8.2.5
Direct access to source data - 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 Clinical Research 
Associate (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 8.2.4.
8.3
QUALITY ASSURANCE AUDIT
A quality assurance audit of this trial may be conducted by the sponsor or sponsor’s 
designees. The quality assurance auditor will have access to all medical records, the

PROCEDURES
8.4.1
Adverse events
An adverse event (AE) is defined as any untoward medical occurrence, including an 
exacerbation of a pre-existing condition, in a patient in a clinical investigation who received a 
pharmaceutical product. The event does not necessarily have to have a causal relationship 
with this treatment.
All adverse events occurring during the course of the clinical trial (i.e., from signing the 
informed consent onwards through the observational phase) will be collected, documented 
and reported to the sponsor by the investigator according to the specific definitions and 
instructions detailed in the ‘Adverse Event Reporting’ section of the Investigator Site File.
A serious adverse event (SAE) is defined as any AE which results in death, is immediately 
life-threatening, results in persistent or significant disability / incapacity, requires or prolongs 
patient hospitalisation, 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 
judgement which may jeopardise the patient and may require medical or surgical intervention 
to prevent one of the other outcomes listed in the above definitions.
All adverse events, serious and non-serious, will be fully documented on the appropriate 
eCRFs. For each adverse event, the investigator will provide the onset, end, intensity, 
treatment required, outcome, seriousness and action taken with the investigational drug. The 
investigator will determine the relationship of the investigational drug to all AEs as defined in 
the 'Adverse Event Reporting' Section of the Investigator Site File. 
The basis for judging the intensity of the AE will be based on the CTCAE criteria version 3.0  
(R04-0474). The basis for judging the causal relationship between the investigational product 
and the AE is described below.
Causal relationship
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. Assessment of causal relationship should be recorded in the case report forms. 
!
Yes:
There is a reasonable causal relationship between the investigational drug 
administered and the AE. 
!
No:
There is no reasonable causal relationship between the investigational drug 
administered and the AE. 
If a SAE is reported from a still blinded trial, the causal relationship must be provided by the 
investigator for all potential trial drugs, i.e. the BI trial drug and for all other trial drugs (i.e. 
any active comparator or placebo according to the trial design).

The investigator has the obligation to report AEs during the specified observational phase. If 
defined in the CTP, the investigator also has the responsibility to report AEs occurring in a 
certain period after a patient completes the trial. Any AEs reported to the sponsor during this 
phase must be documented in the safety database.
If not stipulated differently in the ISF, SAEs are to be reported to the sponsor using the BI 
Serious Adverse Event Report Form including a documented causal relationship assessment 
and providing as much detail regarding the SAE as possible. With receipt of follow-up 
information, all remaining fields on the SAE form are to be completed or updated.
Any serious or significant AE, whether or not considered related to the investigational 
product, and whether or not the investigational product has been administered, must be 
reported immediately by telephone / fax to the sponsor. Expedited reporting of serious 
adverse events, e.g. suspected unexpected serious adverse reactions (SUSARs), will be done 
according to local regulatory requirements. Further details regarding this reporting procedure 
are provided in the ISF.
Following every such telephone / fax report, the Clinical Monitor must provide a written 
report of the serious or significant AE and any sequelae to Corporate Drug Safety according 
to the appropriate Corporate SOP(s). These narratives, which confirm the information 
collected by telephone, may give additional information not available at the time of the initial 
report.
8.4.2
Emergency procedures
Not applicable.
8.5
RULES FOR AMENDING PROTOCOL
All CTP amendments must be documented, dated and signed by all signatories (or their 
successors) of the original protocol. This also applies to any local amendment that may 
become necessary. Amendments (excluding those exclusively for administrative or logistical
changes) need to be submitted to the IEC for approval and to the competent authority (CA) 
for approval. Local Amendments will only be submitted in the countries / centres concerned.)
8.6
DISCONTINUATION OF THE TRIAL BY THE SPONSOR
Boehringer Ingelheim reserves the right to discontinue the trial at any time for the following 
reasons:
1.)
Failure to meet expected enrolment goals overall or at a particular trial site,
2.)
emergence of any efficacy/safety information that could significantly affect 
continuation of the trial
3.)
violation of GCP, the CTP, or the contract by a trial site or investigator, disturbing the 
appropriate conduct of the trial.

APPENDICES
10.1
PHARMACOKINETIC METHODS
10.1.1
Derivation of pharmacokinetic parameters
BI 6727 or Cytarabine plasma concentrations will be plotted graphically versus time for all 
subjects as listed in the plasma concentration-time tables for both analytes.  For the 
presentation of the mean profiles, the arithmetic/geometric mean and the planned blood 
sampling times will be used.
Concentrations will be used for calculations in the format that is reported in the bioanalytical 
report.  The data format for descriptive statistics of concentrations will be identical with the 
data format of the respective concentrations.  For the calculation of pharmacokinetic 
parameters, only concentrations within the validated concentration range will be used.  The 
descriptive statistics of pharmacokinetic parameters will be calculated using the individual 
values with the number of decimal places as provided by the evaluation program.  Then the 
individual values as well as the descriptive statistics will be reported with three significant 
digits in the clinical trial report.  The actual sampling times will be used.  For predose 
samples, the actual sampling time will be set to zero.  
Concentration data identified with NOS (no sample available), NOR (no valid result), NOA 
(not analyzed), BLQ (below the limit of quantification), and NOP (no peak detectable) will 
be ignored and not replaced by zero at any time point (applies also to the lag phase including 
the pre-dose value).  Descriptive statistics of concentrations at specific time points will be 
calculated only when at least 2/3 of the individuals have concentrations within the validated 
concentration range. The overall sample size to decide whether the “2/3 rule” is fulfilled will 
be based on the total number of samples intended to be drawn for that time point (i.e., BLQ, 
NOR, NOS, NOA, NOP are included).
Non-compartmental pharmacokinetic parameters will be determined using WinNonlin or 
another validated program.
In the non-compartmental analysis, concentration data identified with NOS, NOR, and NOA 
will not be considered.  BLQ and NOP values in the lag phase will be set to zero.  The lag 
phase is defined as the period between time zero and the first time point with a concentration 
above the quantification limit. All other BLQ and/or NOP values of the profile will be 
ignored.
If the predose concentration before the first dose is less than or equal to 5% of Cmax value in 
that subject, the subject’s data without any adjustments can be included in all 
pharmacokinetic measurements and calculations (i.e., the predose value will not be changed 
to zero). If the predose value is greater than 5% of Cmax, the subject should be dropped from 
all statistical evaluations. The individual pharmacokinetic parameters can be calculated and 
listed separately.
Every effort will be made to include all concentration data in an analysis. If not possible, a

case to case-to-case decision is required whether the value should only be excluded from 
half-life estimation or the complete analysis.
• If a concentration is only excluded from half-life determination, it will be used for all 
other calculations (e.g., descriptive statistics) and for graphical presentation.
• If a concentration value is excluded from all calculations, it will not be presented 
graphically or used for the calculation of descriptive statistics and parameter 
determination. .  However, the excluded concentration itself will be listed in the clinical 
trial report associated with an appropriate flag.
Descriptive statistics of parameters are calculated only when at least 2/3 of the individual 
parameter estimates of a certain parameter are available. If the actual sampling time will not 
be recorded or will be missing for a certain time point, the planned time will generally be 
used for this time point instead.  Pharmacokinetic parameters which cannot be determined
will be identified by "not calculated" (NC).
Cmax and tmax: Individual Cmax and tmax values will be directly determined from the plasma 
concentration time profiles of each subject. If the same Cmax concentration occurs at different 
time points, tmax is assigned to the first occurrence of Cmax.
Estimation of λz: Τhe apparent terminal rate constant λz will be estimated from a regression 
of ln(C) versus time over the terminal log-linear disposition portion of the concentration-time 
profiles. The log-linear profiles, which include the regression line through the terminal 
points, will be checked via visual inspection, and it will be determined whether the regression 
appropriately represents the terminal slope. A minimum of three points will be used in the 
determination of λz. If the last concentration-time point increases, this time point may be 
included if the t1/2 estimate is reasonable. If λz is not determinable then consequently only 
parameters not requiring λz will be reported. In addition, the lower (tλz,start) and upper (tλz,end) 
limit on time for values to be included in the calculation of λz will be listed.
t1/2: The terminal half-life will be calculated from the terminal rate constant using the 
equation

AUC: The area under the curve will be calculated using the linear up/log down algorithm. If 
an analyte concentration is equal to or higher than the preceding concentration, the linear 
trapezoidal method will be used. If the analyte concentration is smaller than the preceding 
concentration, the logarithmic method will be used.

INTRODUCTION 
This TSAP will describe both the analyses for the final CTR as well as the analyses made for 
the safety update after phase I (see section 9.5). 
3.1 
CLINICAL OBJECTIVES 
See section 2.1 of the CTP. 
3.2 
STATISTICAL DESIGN / MODEL 
The trial will be performed as an open label study. In phase I patients will be assigned to the 
two treatment schedules (BI 6727 monotherapy and BI 6727 in combination with LD-Ara-C, 
respectively). In phase II patients will be randomly allocated to one of the two different 
treatment schedules BI 6727 in combination with LD-Ara-C and to a monotherapy schedule 
with LD-Ara-C only, respectively. To determine the two separate MTDs in the phase I part, 
cohorts of patients will be entered sequentially into escalating dose tiers using the 3+3 design 
with dose de-escalation. 
3.3 
NULL AND ALTERNATIVE HYPOTHESES 
All analyses in this study are descriptive and exploratory by nature. Any statistical tests are 
performed only to provide a statistical framework from which to view the results and 
providing aid for planning further studies. No formal statistical tests are foreseen. 
3.4 
STATISTICAL SOFTWARE 
or higher will be used for all analyses.

CHANGES IN THE PLANNED ANALYSIS OF THE STUDY 
- 
An additional comparison of objective response rates based on a Bayesian approach 
has been added. 
- 
Blood products uses have been added as another endpoint in order to reflect 
supportive care requirements. 
- 
The definition of relapse-free survival and remission duration has been changed. The 
definition now includes patients who have best response of CR or CRi and not only 
patients with CR in order to correct a misprint in the CTP. 
- 
Genetic groups have been defined and the analysis of overall response, event-free 
survival and overall survival in these subgroups has been added.

ENDPOINTS 
5.1 
PRIMARY ENDPOINTS 
This study has two separate primary endpoints for the phase I part and the phase II part. The 
primary endpoint for the phase I part is the determination of the two separate MTDs (mono 
and combi) as reflected by the dose limiting toxicities (DLT) events in course 1. The primary 
endpoint for the phase II part is objective response. 
 5.1.1 
Primary endpoint related to safety 
The primary objective related to safety (phase I part) of this trial is to determine the MTDs of 
BI 6727 mono and BI 6727 in combination with LD-Ara-C. This will be done in the phase I 
part of the trial. Two separate MTDs for the two schedules will be determined. 
Maximum tolerated dose (MTD):  
The MTD for BI 6727 monotherapy is defined as the dose of BI 6727 (without LD-Ara-C), 
which is one dose tier below the lowest dose at which two or more out of six patients 
experienced DLT. The MTD for the combination schedule of BI 6727 and LD-Ara-C is 
defined analogously. 
5.1.2 Primary endpoint related to efficacy 
The primary endpoint for efficacy (phase II part) in this study is objective response. This 
primary endpoint will be determined in the phase II part of the study. For the phase I part this 
endpoint will also be determined but will be considered as secondary only. 
In order to evaluate the objective response, the investigator's assessment as given in the eCRF 
will be taken into account (no central review and no check vs. bone marrow measurement is 
planned). Both investigator assessments (clinical progression as well as response assessment) 
will be taken into account for the determination of objective response. In particular this 
means that a patient is considered as ‘progressive disease’ if any of the assessments indicates 
a progression of the disease. 
No confirmation of a response / stable disease is necessary, i.e. in the following only 
unconfirmed responses are considered. 
Evaluation of objective response: 
The different categories possible for overall response (at a specific timepoint) are provided in 
section 9.6. In order to derive objective response the secondary endpoint best overall 
response will be derived first. 
The best overall response is the best overall response recorded during the time period from 
the start of the treatment until end of treatment period, progression or death whichever is 
earlier. Possible categories for best overall response are complete remission (CR), complete 
remission with incomplete blood recovery (CRi), partial remission (PR), no change (NC), 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 10
 
progressive disease (PD) and no assessment. Patients dying before any assessment will be 
summarized under PD regarding best overall response.  
Objective response (yes/no) is yes if the best overall response is either CR or CRi, otherwise 
it is no. 
Objective response including PR (yes/no) is yes if the best overall response is either CR, CRi, 
or PR otherwise it is no. 
5.2 
SECONDARY ENDPOINTS 
5.2.1 
Event free survival 
Event-free survival (EFS) [days] is the shortest duration of the following:- 
- dates of assessment indicating 'progressive disease' on RESPONSE page of eCRF – 
date of randomisation + 1day, 
- dates of assessment indicating 'clinical progressive disease' on DISEASS or 
RESPONSE-page of eCRF– date of randomisation + 1day, 
- dates of assessment indicating 'progressive disease' on PAT_STATUS of eCRF – 
date of randomisation +1 day (for patients who have not been censored before, see 
below) 
- death date – date of randomisation +1day. 
Date of assessment refers here to the progdt as given in the eCRF. If progdt is missing then 
the corresponding examdt will be taken instead if available. Progression events are only taken 
into account if the corresponding date is before the start date of a new anti-leukemia therapy 
(see below for censored patients). 
Patients not being assessed 'progressive disease', clinical progressive disease' or death during 
the trial will be censored as described below. These patients must be reviewed on a case by 
case basis by the trial statistician (TSTAT) and trial clinical monitor (TCM). 
Right censoring rule for event-free survival (EFS): 
Patients getting a new additional other anti-leukemia therapy recorded at the eCRF (follow-
up) but not being assessed 'progressive disease', clinical progressive disease' or death before 
the new anti-leukemia therapy was started will be censored at the date of last disease 
assessment before the new anti-leukemia therapy was started (excluding follow-up). 
Event-free survival censored [in days] is the time from randomisation to the date of last visit 
(Date of last visit (including follow-up) – date of randomisation + 1 day) for  all other 
patients not being assessed 'progressive disease', clinical progressive disease' or death at the 
time of data base lock. Date of last visit does not include visit dates from follow-up where 
'lost to follow-up' = yes. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 11
 
EFS will be reported in days. 
Patients without any response assessment (best overall response = no assessment) and 
without death will be censored with an EFS of 0. Otherwise the death date will be used. 
5.2.2 
Overall survival 
Overall survival [in days] = (date of death - date of randomisation + 1 day), for patients with 
known date of death. 
Overall survival (Censored) [in days] = (date of last trial visit (or follow-up) - date of 
randomisation + 1 day), for patients who are still alive at time of data base lock. Date of last 
visit does not include visit dates from follow-up where 'lost to follow-up' = yes. 
Overall survival will be reported in days. 
5.2.3 
Relapse-free survival, remission duration and time to remission 
Relapse-free survival / Remission duration is defined only for patients with a best overall 
response of CR or CRi. 
Relapse-free survival [in days] = (date of first recurrence of disease or death after entering the 
trial – date of first occurrence of CR or CRi after entering the trial+ 1 day) for patients with a 
recurrence (this value should be positive). 
Relapse-free survival (censored) [in days] = (date of last trial visit (or follow-up) - date of 
first occurrence of CR or CRi after entering the trial + 1 day) for patients who did not yet 
experience recurrence of disease or death at the time of analysis. 
Remission duration is defined analogously with the exception of censoring patients that die 
before recurrence. 
Time to remission [in days] = (date of first occurrence of CR or CRi after entering the trial – 
date of randomisation + 1 day) for patients with an objective response (this value should be 
positive). 
Date of first recurrence of disease is given by the first date of being assessed as either 
'progressive disease', 'clinical progressive disease' or death after the first occurrence of CR or 
CRi after entering the trial. If a patient has either no date of being assessed as either 
'progressive disease', 'clinical progressive disease' or death or no occurrence of CR or CRi 
after entering the trial this date is missing and will also not be imputed. 
5.2.4 
Eastern Cooperative Oncology Group (ECOG) performance score 
ECOG score: as given on the eCRF. 
ECOG score change from baseline to last visit of last course = ECOG score at last visit of the 
last course – ECOG score at baseline. See also section 6.4 for missing ECOG scores. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 12
 
Categorical ECOG score change: The ECOG score changes from baseline score will be 
categorized on a three point categorical scale: deteriorated (-1), unchanged (0), and improved 
(1). Improvement or deterioration of performance status will require a decrease or an increase 
from baseline, respectively, of at least one point on the ECOG scale. 
5.2.5 
ECG/QTc 
The following endpoints will be regarded for the ECG analysis. 
• QTcF changes from baseline at each time point: the QTcF post baseline measurement 
obtained at time t minus baseline QTcF measurement. 
• Absolute QTcF intervals at each time point. 
The above endpoint will also be computed for the uncorrected QT interval, for the heart rate 
(HR), PR interval and QRS duration. The heart rate (HR) will be derived from RR intervals. 
• Categories of QTcF values at baseline and maximum post baseline: 
QTcF ≤  450 ms, 450 ms < QTcF ≤  470 ms, 470 ms < QTcF ≤  500 ms, and QTcF  > 500 
ms (notable prolongation) 
• Categories of QT values at baseline and maximum post baseline: 
QT ≤  500 ms and QT  > 500 ms (notable prolongation) 
• Categories of the QTcF increase from baseline to the maximum post-baseline value: 
intervals for a given patient as QTcF ≤  30 ms, 30 ms < QTcF ≤ 60 ms, QTcF > 60 ms, 
(the latter increase reflects a notable change) 
• Categories of the QT increase from baseline to the maximum  post-basline value: 
intervals for a given patient as QT ≤ 60 ms and QT > 60 ms (the latter increase reflects a 
notable change) 
All endpoints derived for the QTcF interval will also be derived for the QTcB interval. 
5.2.6 
Adverse events 
According to the BI standards, multiple recordings of AEs will be collapsed to episodes on 
the lowest level term and for each patient, all episodes with the same PT(SOC) will be 
condensed to one AE record using a worst case approach for all AE attributes including 
CTCAE grading. This AE record per PT (SOC) forms the basis for all standard AE analysis 
on the patient level. CTCAE grade will be displayed in AE listings. MedDRA levels for 
condensing will be SOC and PT. AE listings will in general display records. A listing of 
episodes and occurrences will be provided. 
AEs with action taken 'discontinued' or 'reduced' will be considered as marked on the eCRF 
irrespective of seriousness. Hence this includes the non-serious AEs considered as 'other 
significant' by ICH E3. No type of AE has been predefined as 'significant' in the CTP. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 13
 
Dose limiting toxicities (DLT) events will be identified by the relevant question on the eCRF.  
5.2.7 
Laboratory parameters 
In this trial the original laboratory values will be converted into standard units and the 
CTCAE grades will be assigned to all parameters which have a CTCAE definition. For this 
study, the laboratory parameters and their functional groups, together with the direction of 
concern, which were to be recorded and which have a CTCAE criteria definition are:- 
Haematology: Haemoglobin (HGB) (-), white blood cells (WBC) (-) and Platelets (-) 
Differentials: Neutrophils (-) and Lymphocytes (-) 
Electrolytes: Sodium (+ and -) and Potassium (+ and -) 
Enzymes: AST (+), ALT (+), Alkaline Phosphatase (ALKP) (+), Troponin (TPONT) (+) 
Substrates: Total bilirubin (+), Glucose (+ and -) and Creatinine (+) 
Coagulation: International Normalised Ratio of prothromin time (INR) (+) and Partial 
thromboplastin time (APTT) (+) 
The signs + (-) means the above (below) the reference ranges. 
It is important to note that these above described values are the only parameters that can be 
graded according to CTCAE criteria. The other parameters reported cannot be graded 
according to CTCAE criteria. 
The change of the laboratory value will be calculated for all laboratory parameters from the 
baseline to the end of the treatment for the whole treatment duration. No post-study 
laboratory values will be considered. 
Worst lab value and its CTCAE grade (highest CTCAE grade) over all courses will be 
calculated for each laboratory parameter specified above.  
The last lab value on treatment is the lab value of the last visit of the last course of each 
patient.  
The change of the CTCAE grade of the lab value will be calculated 
• from baseline to the last lab value on treatment 
• from baseline to the worst value on treatment 
 
Note: For calculating the change in CTCAE grade from baseline/ pre-dose level, patients with 
a CTCAE grade of -9 at baseline will be reviewed on a case-by-case basis. If there is no 
evidence that the corresponding laboratory value is of clinical significance, these values will 
be changed to -7 and treated as a CTCAE grade of 0 for analyses. All other values with 
CTCAE grade -9 will be regarded as CTCAE grade -8. Values with a CTCAE grade of -8 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 14
 
will either be removed from analyses concerning determination of baseline and worst 
CTCAE grade or if needed the category “not covered by CTC criteria” will be included. 
Values with CTCAE grades of -7 and -8 will be displayed in two separate listings. 
In a similar manner, patients with a CTCAE grade of -1 will be reviewed on a case-by-case 
basis. For uric acid, values with CTCAE grade -1 will be regarded as either CTCAE grade 3 
or CTCAE grade 1, depending on whether accompanied with physiological consequences 
(grade 3) or not (grade 1). A listing of the laboratory values with an assigned grade of -1 will 
be provided together with the re-assigned grade. 
5.3 
OTHER ENDPOINTS 
5.3.1 Demographics and baseline characteristics 
Number of previous systemic anti-leukemia therapies: Derived from PSYSTETHER page in 
the eCRF 
Number of previous anti-leukemia radiotherapies: Derived from PRADIOTHER page in the 
eCRF 
Previous systemic anti-leukemia therapies that have the same start date and end date will be 
counted as a single anti-leukemia therapy. Previous therapies with the same compound but 
different start dates or end dates will be counted separately. These rules apply even in case of 
overlapping or time-adjacent dates. 
With respect to previous radiotherapies the same rules apply as for systemic anti-leukemia 
therapies. 
Time since last systemic anti-leukemia therapy [months]: = (date of informed consent - end 
date of the last systemic anti-leukemia therapy + 1 day) [days] / 30. 
Time from first cytological diagnosis [years] = (date of informed consent - date of first 
cytological diagnosis + 1) [days] / 365.25) 
Age at the first Cytological diagnosis [years] = (date of first cytological diagnosis – birth 
date+1)[days] / 365.25) 
Secondary AML: Secondary AML is yes if the respective answer on the eCRF page is given. 
Otherwise Secondary AML is no and the patient is considered to have de novo AML. 
Karyotype is considered ‘complex’ if cytogenetics are available (cytogenetics = yes on the 
eCRF) and the corresponding specification equals 2. It is considered ‘normal’ if cytogenetics 
are available and specification equals 1. It is considered ‘neither’ if cytogenetics are available 
and specification equals 2. Otherwise it is considered missing or not evaluable. 
Findings for molecular genetics (e.g. t(8,21), inv16 and NRAS gene mutation) and the WHO 
classification of AML and related neoplasms will all be taken directly from the corresponding 
question on the eCRF page.

 Extent of exposure 
Number of days of administration BI6727 [N]: Cumulative number of days with an 
administration of BI 6727. 
Number of days of administration Cytarabine [N]: Cumulative number of days with an 
administration of cytarabine. 
Number of courses initiated [N]: course initiated means: the patients received at least one 
administration of BI 6727 or cytarabine in the initiated course. 
Cumulative total dose BI6727 [mg] = Sum of doses (administered dose of BI 6727) 
calculated across all courses 
Total dose BI 6727 [mg] within a course = Sum of doses (administered dose of BI 6727) 
calculated per treatment course 
Similar variables (cumulative total dose) will also be derived for LD-Ara-C. 
Total exposure time to the trial drug [days] = date of first administration to MINIMUM (date 
of last trial drug administration of the last course + 21 days, death date if death occurs earlier 
than 21 days) + 1 day 
Total observation time [days] = (last visit date (including follow-up) - date of randomisation 
+ 1 day). Date of last visit does not include visit dates from follow-up where 'lost to follow-
up' = yes. 
The following two characteristic apply to BI 6727 only: 
Number of patients with at least one dose escalation will be counted. A patient is considered 
to have at least one dose escalation if a dose escalation occurred at least once with BI 6727. 
Number of patients with at least one dose reduction will be counted. A patient is considered 
to have at least one dose reduction if a dose reduction occurred at least once with BI 6727. 
5.3.3 
Other relevant observation related to safety 
Vital signs will be recorded at baseline (including body weight), at each visit of each course 
and end of trial for each patient. Change from baseline to the end of the trial will be derived 
for each patient. Vital signs will be recorded also during infusion. If there are multiple 
measurements at a specific time point for vital signs, the last value will be taken. 
Changes from baseline to the end of the trial = Parameter at end of the trial – parameter at 
baseline. 
Percent change from baseline at the end of the trial = 100*(parameter at the end of the trial – 
baseline parameter) / baseline  parameter.

IMPORTANT PROTOCOL VIOLATIONS 
Due to the fact that this is a phase I/II study, no per protocol population is needed, however 
important protocol violations should be identified for patients in the treated set both for phase 
I and II (any protocol violation which may affect safety or efficacy evaluation).

PATIENT SETS ANALYSED 
Two analysis populations are defined according to the different trial phases for both the 
efficacy and safety analyses. For the phase I part the treated set (phase I) is defined, in 
analogy to the intention to treat population as the treated set with respect to phase I; i.e. all 
patients of phase I who have received at least one single dose of either BI 6727 or cytarabine 
will be considered, including the patients who have been replaced for any reason. 
For the phase II part the treated set (phase II) is defined, in analogy to the intention to treat 
population as the treated set with respect to phase II; i.e. all patients of phase II who have 
received at least one single dose of either BI 6727 or cytarabine will be considered, No per 
protocol population will be used for analyses. However protocol violations will be described.

6.5 
POOLING OF CENTRES 
All centres will be analyzed together, with any centre effects being ignored. Country or 
region effects will also not be considered. This means that the patient sets analysed will be 
defined without taking into account the centre a patient comes from. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 26
 
For the primary endpoint in phase II (objective response) any centre effects will be analysed 
descriptively if necessary. 
6.6 
HANDLING OF MISSING DATA AND OUTLIERS 
Missing or incomplete AE dates are imputed according to BI standards ([3.]) 
Missing data and outliers of PK data are handled according to [1.]. 
If not stated otherwise, missing data will not be imputed and remain missing. Potential 
outliers will be reported and analysed as observed. 
ECOG Performance Score 
In case that the very last ECOG score is missing the ECOG score with the latest date 
available will be used if the latest date is after baseline. Otherwise ECOG remains missing. 
Laboratory values, vital signs: 
In case of missing data at visit 1 (before very first administration of BI 6727), the data of 
preceding visits will be used if not obtained longer than seven days before treatment course 1. 
Missing of dates: 
Dates that must have taken place before informed consent (e.g time of first cytological 
diagnosis) 
If (only) the day is missing then day 15 will be imputed except if day 15 is later than 
the informed consent day, then the date of informed consent will be imputed. 
If the month is missing (additionally to the day) then July 1st will be imputed except 
if July 1st is later than the informed consent month, then the month of informed 
consent will be imputed. 
Other dates 
For other dates, if the day is missing then day 15 will be imputed. If the month is 
missing then July 1st will be imputed. 
Missing PHYSDT: 
In general if a physdt is missing (e.g. for ECOG or weight) the corresponding visdt will be 
used. Since visdt will not be cleaned such imputations need to be examined for appearing 
impossible results. 
Missing of infusion time: 
If the time of infusion is missing, then the start time of the infusion will be imputed as "0:00" 
and the stop time will be imputed as “1:00”. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 27
 
Missing administration times LD-Ara-C:  
If the start time of the first injection is missing, then the start time of the injection will be 
imputed as "0:00" If the stop time of the last injection is missing the new stop time is 23:59. 
Start and end dates of concomitant therapies: 
The dates will be imputed such that the extent of exposure to concomitant therapy is 
maximal, i.e. the first day (month) of the month (year) for incomplete start dates and the last 
day (month) of the month (year) for incomplete end dates. 
6.7 
BASELINE, TIME WINDOWS AND CALCULATED VISITS 
Study days and visits will be labelled according to the flow chart of the CTP. 
Unless otherwise specified, baseline is defined as the latest time-point before the very first 
treatment administration (≤ 7 days before first administration). If this criterion is not fulfilled 
then no baseline will be derived. 
For height baseline is defined as the latest time point before the very first treatment 
administration (no 7-day-rule). 
ECOG: 
Baseline is defined as value at the day of first administration. If there is no value available at 
the day of first admin, the latest value before the first admin will be used. 
Laboratory values/ other safety measurements: 
Baseline is defined as value at time point closest to but prior to first administration of trial 
medication of the first course. (i.e. Time of laboratory value on day of first administration <= 
time of first administration, then lab value on day of first administration = lab value at 
baseline. If time of lab value on day of first administration > time of first administration then 
closest non-missing lab value before time of first admin = lab at baseline) 
If any of these times are missing and date of lab = date of first admin, then lab at first admin 
= lab at baseline. 
 
ECG 
Baseline ECG is available from three time points (prior infusion at course 1 visit 1, course 1 
visit 4 and course 2 visit 1). To account for possible variations between the study days, two 
different baseline definitions will be used: 
1. Individual baseline is defined as the mean of the triplicate at the time point closest to but 
prior to the start of the infusion at each time point, i.e. each time point has its own 
baseline. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 28
 
2. Combined baseline is defined as the mean of the (three) triplicates at the time points 
closest to but prior to the start of the infusion at the three time points, i.e. a common 
baseline is used. 
Day 1 will be the day of randomisation, so time to event will be taken from Day 1. 
6.8 
GENERAL CALCULATION RULES 
Months = days / 30, Years = days / 365.25 = months / 12 
In the case of having multiple values at one visit, for example, laboratory data or vital signs, 
then the worst case will be used, for post baseline values. Note that pre-treatment values are 
handled under ‘baseline’. To determine worst case, in the case of laboratory data, section 
5.2.2 indicates the worst case. In the case of vital signs, the minimum value will be used for 
weight and the maximum value for ECOG.

PLANNED ANALYSIS 
For in-text tables, the set of summary statistics is: N (number of patients with non-missing 
values), mean, standard deviation (SD). 
For end-of-text tables, the set of summary statistics is: N / Mean / SD / Min / Median / Max.  
For appendix tables, the set of summary statistics is: N / Mean / SD / Min / Q1 (lower 
quartile) / Median / Q3 (upper quartile) / Max. 
Tabulations of frequencies for categorical data will include all possible categories and will 
display the number of observations in a category as well as the percentage (%) relative to the 
respective treatment group. Percentages will be rounded to one decimal place. The category 
missing will be displayed if and only if there are actually missing values. Percentages will be 
based on all patients in the respective patient set whether they have non-missing values or 
not. 
In general all analyses will be performed for the treated set (phase I) and the treated set 
(phase II) separately. No pooling across these two treated sets will be performed unless noted 
otherwise. 
7.1 
DEMOGRAPHIC AND OTHER BASELINE CHARACTERISTICS

treated set by treatment group. At the report planning meeting it will be decided which 
additional variables will be tabulated in chapter 15 or the interim section of the CTR. 
Disposition of patients 
Standard descriptive analysis of the disposition will be provided.  
If applicable, the number of patients who will continue treatment after database lock will be 
reported in the disposition table, separately. 
Additionally, patients with discontinuations of the trial medication due to DLT will be listed 
by treatment and the reasons will be given. Listing of all patients with dose changes will be 
provided. 
Important protocol violation 
A table or listing of patients with protocol violations will be created.  
Demographics and baseline characteristics 
Standard descriptive analysis of the disposition will be provided.

7.2 
CONCOMITANT DISEASES AND MEDICATION 
Only descriptive statistics are planned for this section of the report. 
A summary of the most frequently concomitant medication (drug classes and generic Name 
for patients with medication at generic Name) during the treatment and before starting of 
treatment will be reported. Separate listings/tables will be provided for therapy starting before 
therapy and those therapies starting after first administration of the trial drug. A summary of 
the most frequently concomitant diseases (system organ class (SOC) and PT) will be 
reported. A summary of concomitant therapy will be given. 
Listings of the data will present the concomitant therapy PT and verbatim text as well as the 
verbatim text of the indication. In addition the listings will include study day for start and 
stop dates and duration of therapy. Patients with no concomitant therapy will not be included 
in the listing. The number of these patients will be presented by a footnote. 
7.3 
TREATMENT COMPLIANCE 
Only descriptive statistics of the variable "all administration according to the protocol" are 
planned for this section of the report. "all administration according to the protocol" equals 'no' 
if any of the entries for 'Administration according to protocol' equals 'no'. Otherwise it is 'yes'. 
The variable will be derived separately for BI 6727 and cytarabine if applicable. 
For patients with "all administration according to the protocol" equals 'no' a listing will be 
presented. 
7.4 
PRIMARY ENDPOINTS 
One primary objective for this study is the tolerability and safety of the BI 6727 in each 
treatment schedule as reflected by the MTD (phase I part). Refer to section 7.7 for a 
description of the analysis of safety and tolerability.  
The primary endpoint for efficacy in the phase II part is objective response derived from the 
data of all courses. The primary analysis of efficacy will be done for all patients of the treated 
set (phase II) for both treatment schedules separately. Patients with objective response will be 
listed (both phase I and phase II). 
7.4.1 
Statistical Group Comparisons 
All statistical group comparisons will be performed with respect to the treated set (phase II) 
The comparison of the treatment schedule to the control schedule will be based on the 
conditional power approach and on a stopping for futility check [7.,8.]. The conditional 
power for showing superiority of a treatment schedule with respect to the control schedule at 
a later time point will be evaluated assuming that the final analysis is the interim analysis of a 
larger trial. These calculations will be based on an O'Brien-Fleming design with interim 
analysis to stop for futility. The assumptions are an information fraction of 60% of patients, 
an overall type I error of 5% (one-sided), 15% objective response rate in the control vs. 30% 
objective response rate in experimental arm and a power of 65% as described in the CTP. The 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 31
 
conditional power will be computed under the current trend hypothesis [8.] using the 
standardized logarithm of the odd's ratio of proportions as a test statistic (approximately 
N(0,1) distributed). 
 will be used for these computations. 
Additionally, similar computations will be performed for other scenarios with a planned 
sample size of approximately 86 patients at the assumed interim analysis (25% information 
fraction, alpha=0.025 and power 90%, 33% information fraction, alpha=0.025 and power 
80% as well as 40% information fraction, alpha=0.05 and power 80%). 
The conditional power will be evaluated in addition under the null hypothesis of no treatment 
effect and under the assumption that the true treatment effect (measured as the log odds ratio) 
captures only 50% of the observed treatment effect in order to check the robustness of the 
result. 
Odds ratios, confidence intervals, and Fisher’s exact test will be used to compare treatments 
in an exploratory manner if appropriate. 
Additionally, objective response rates will be evaluated by a Bayesian approach with a non-
informative prior (9.) given by a beta(1,1) distribution. Denoting the total number of patients 
per arm by n and the number of responders per arm by r this leads to a beta(1+r,1+n-r) 
distribution for the posterior (per arm separately). 
Based on this approach the following posterior probabilities will be evaluated: Probability 
that the treatment arm is at least as good as the control arm, probability that the treatment arm 
is at least 5% better than the control arm, probability that the treatment arm is at least 10% 
better than the control arm. Evaluation is performed based on simulating the posterior 
distribution for each arm m=1000000 times and by evaluating the respective characteristics. 
The exploratory nature of these analyses will be considered when interpreting the 
significance levels. P-values derived from statistical tests smaller than 5% will only be 
reported as nominally significant regarding the small sample size in each treatment schedule. 
For the genetic subgroups defined in Section 6.4 frequency tables of best overall response 
will be presented. 
7.5 
SECONDARY ENDPOINTS 
Event-free survival (EFS) 
EFS will be analyzed with the Kaplan-Meier method for each of the treatment arms as well as 
overall treatments. An exploratory (non-stratified) logrank test will be used to compare the 
different treatment arms. For phase II Kaplan-Meier curves for EFS in the genetic subgroups 
defined in Section 6.4 will be presented separately. 
The percentage of patients who are event free will be displayed at monthly or greater time 
intervals as appropriate.  


Boehringer Ingelheim

Page 32
 
Patients for whom no leukemia assessment is available within 42 days prior to 
discontinuation from treatment will be examined on a case by case basis. A listing will be 
provided. 
Overall survival 
Overall survival will be analyzed in a manner similar to that of event-free survival. 
Remission duration 
Remission duration will be summarized by treatment group. Kaplan-Meier plots of the 
relapse-free survival will be displayed without displaying hazard rates, associated confidence 
intervals and p-values. Expected duration of response will be calculated based on an 
exponential model if appropriate. 
Note that for remission duration no formal comparison between different treatment arms will 
be done since remission duration is based on a non-randomised set and therefore possibly 
biased. 
ECOG performance score 
The proportion of patients with improved (decreased), and with unchanged, ECOG at end of 
treatment with respect to baseline will be tabulated. 
BI 6727 plasma concentration

Pharmacodynamic monitoring 
Analysis of pharmacodynamics will be performed separately and will not be contained in the 
CTR. 
Pharmacogenetics 
Analysis of pharmacogenetics will be performed separately and will not be included in the

7.6 
EXTENT OF EXPOSURE 
Standard descriptive analysis is planned for overall courses/visits by treatment groups. 
7.7 
SAFETY ANALYSIS 
All safety analyses will be performed on the treated sets (separately for phase I and phase II).

7.7.1 
Adverse events 
The analyses of adverse events will be descriptive in nature and will be based on BI standards 
(see [3.]). Adverse events will be coded with the most recent version of MedDRA. According 
to the BI standards, multiple occurrences of adverse events are collapsed to episodes if time 
overlapping or adjacent (maximal one day) on the MedDRA lowest level term and multiple 
episodes will be condensed to records on the preferred term and SOC level.  
AEs as well as DLTs will be evaluated both for all courses as well as for first course only (in 
the phase I part). 
The analysis of adverse events will be based on the concept of treatment emergent adverse 
events. Adverse events will be distinguished for the period in which the subjects are under 
study drug (on-treatment) as well as for screening, and post-study (For details on the 
analysing treatment period, see section 6.1.3). If applicable, the actual dosage of BI 6727 
administered on the day each adverse event starts will also be derived and will be included in 
the listing. The system organ classes will be sorted according to the standard sort order 
specified by EMEA, PTs will be sorted alphabetically (within SOC). 
All patients will be reported in the summary tables under the initial treatment group 
(randomised treatment) including the initial treatment schedule. 
AEs with onset date at Screening- and Post-study-period (as defined in Table 6.1.1: 1) will be 
displayed in two separate listings. Listings of screening events will not be sorted by initial 
treatment (Table 6.1.2: 1). But post-study listings will be sorted by initial treatment. 
AE flags and attributes 
An AE flag will be defined for patients who developed an AE that was CTCAE grade >= 3, 
DLT, or serious AE. 
An AE attribute "CTCAE grade 3/4 or 5 combined with drug relation" will be derived to 
avoid incorrect condensing. Consider, for instance, a patient with coincident drug-related 
abdominal pain with CTCAE 1, and non-related vomiting with CTCAE 3. Without the new 
attribute these AEs would be reported as drug-related Grade 3/4 under the SOC 
Gastrointestinal disorder. With the new AE attribute these AE would not be reported under 
that category. 
The number of patients with DLT will be listed per treatment group with the respective 
events fulfilling the criteria for DLT. 
A separate listing for all patients who developed AEs with CTCAE grade >= 3, DLT, and 
serious AEs will be generated. 
Incidence and intensity of adverse events 
The overall incidence and intensity of adverse events, as well as relatedness of adverse events 
to treatment with BI 6727 will be reported for all treatment schedule arms. 


Boehringer Ingelheim  
TSAP for BI Trial No: 1230.4 
Page 34
 
Serious adverse events will be tabulated. In addition, Events leading to dose reduction or 
treatment discontinuation will be examined, but may not be reported as individual tables, 
depending upon the extent of overlap with the occurrence of DLT. 
For the phase I part only, the dose-toxicity relationship will be examined descriptively and 
inferentially, using DLTs in treatment course 1 and DLTs up to the end of the on treatment 
phase, in separate analyses. Further, the time to first DLT will be explored descriptively in all 
dose groups, and Kaplan-Meier plots based upon the MTD group will be presented. 
As a first step, for each time period, the number of DLTs that a patient has will be 
summarised. If the majority of the patients have either 0 or 1 DLT, then a simple logistic 
regression will be calculated. If however, there are quite a few patients with >1 DLT, then a 
proportional odds model will be used. 
With this logistic regression, a model including only the BI 6727 dose (and intercept) will be 
used. Hence, by back-transformation of the logit model, the probability (and 95% confidence 
interval) of a DLT in this time period will be presented on a graph together with the dose. 
The dose corresponding to a 25% probability of a DLT in the time period will be indicated 
and the p-values for the intercept and slope of this model will also be included in the 
footnote. Additionally the expected toxicity level for the dose chosen in phase II will be 
provided. 
Finally, the time on treatment prior to the first DLT will be presented graphically together 
with the dose. Different symbols will be used for patients with (filled dot) and without 
(unfilled dot) a DLT. Using the MTD group, the Kaplan Meier plot estimating the probability 
of an event over time will be presented. 
7.7.2 
Laboratory data 
The analyses of laboratory data will be descriptive in nature and will be based on BI 
standards (see [5]) The CTCAE grade will be calculated for each lab value (see section 9.2).  
The baseline, last value on treatment and corresponding change from baseline will be 
presented using N, median and interquartile range. This will be done for all continuous 
laboratory parameters using the BI normalised values, except, however, in the case of WBC 
differentials (Neutrophils and Lymphocytes) which have been recorded in percentage. These 
have been re-derived to normalised values in such a way that the accuracy of decimal places 
is maintained for longer. This is documented in section 9.2. 
Patients with clinically relevant laboratory abnormalities, as defined in section 9.1 will be 
summarised. Project-specific rules for flagging possible clinically significant abnormal 
laboratory values will be applied. 
Patients will be counted under the initial treatment group. Separate listings for patients treated 
under different doses will be created. Thereby the data will be reported under course regimen. 
The analysis of lab data will use the same analyzing treatment periods as described for the 
AEs. 


Boehringer Ingelheim

Page 35
 
Single time courses by treatment regimen will be used to display laboratory values over time. 
The graphs may be truncated if no sufficient data is available. These graphs will be produced 
for absolute neutrophile count, platelets, Creatinine phospokinase, haemoglobin, and for other 
laboratory parameters (if considered important in this trial, decision will be given in URPM 
of the final analysis). 
7.7.3 
Vital signs 
Descriptive statistics of absolute values (and change from baseline) of vital signs (including 
body weight at baseline) will be provided by treatment group, for actual time and visit over 
all courses. Vital signs during infusion will be analysed descriptively. 
7.7.4 
ECG / QTc 
Newly emergent abnormalities will be recorded and analyzed as adverse events. 
7.7.4.1 
Derivation of ECG endpoints 
Three replicate digital ECG recordings will be collected at each time-point. Each of the three 
recorded single ECGs will then be evaluated for cardiac intervals, which comprise the RR, 
PR, QT interval and QRS duration. Measurements of these intervals will be made on four 
(possibly consecutive) waveforms from the lead chosen (usually lead II). The measurements 
of the waveforms will be stored in the database, i.e. twelve values per time-point. The four 
waveforms will be averaged prior to the calculation of the heart rate and heart rate corrected 
QT intervals. Further aggregation of the three replicate QT/QTc intervals and heart rates at 
each scheduled time-point will be performed using arithmetic means. These values will be 
used for the derivation of the ECG endpoints as they are specified in Section 5.3.5. 
The heart rate will be derived from the RR interval as 
HR [bpm] = 60000/RR [ms] 
For each QT interval, the RR interval preceding the QT interval will be used for frequency 
correction. 
Heart rate corrected QT intervals (generally denoted as QTc) will be calculated using 
Fridericia’s (QTcF) and Bazett’s formulas (QTcB):

7.7.4.2 
ECG Analysis 
Absolute values and change from baseline in QTcF, QTcB, QT, PR intervals, HR, and QRS 
duration will be summarised descriptively by course for the MTD groups (including patients 
treated at the MTD in Phase II) using the Treated Set. 
Frequencies of the increases in QTcF/QTcB/QT intervals above thresholds such as 450 ms, 
470 ms and 500 ms between baseline and on-treatment will be displayed in two-way shift-
tables by initial dose for the Treated set. 
Frequencies of patients with increases from baseline in QTcF, QTcB and QT intervals above 
the defined thresholds and notable findings will be displayed, as well. 
Frequency tables by overall clinical interpretation and findings possibly impacting interval 
measurement, and a new onset (not present at baseline) of an abnormal finding will be 
generated. 
7.7.5 
Pharmacokinetics 
The analysis of standard PK parameters is performed according to [2.]. 
The distribution of BI 6727 plasma concentrations will be graphically inspected and 
summarised by time point in the CTR.  
If felt necessary based on the clinical outcome, BI 6727 pharmacokinetic parameters (Cmax, 
exposure, eg AUC) will be correlated with the observed neutropenia, leukopenia and 
leukemic myeloblasts. 
7.7.6 
Others 
If considered necessary, the number of patients who died, and the number of patients who are 
lost to follow-up will be listed by treatment regimen at follow-up-visits. 
Blood products used will be listed by patient.
