Title of trial:
Safety, tolerability, pharmacokinetics and pharmacodynamics of multiple rising 
intravenous doses of BI 655130 (double-blind, partially randomised within dose 
groups, placebo-controlled parallel group design) and one single intravenous dose of 
BI 655130 (single-blind, partially randomised, placebo-controlled) in healthy male 
subjects
Principal Investigator:
Trial site:
Clinical phase:
I
Objectives:
To investigate safety, tolerability, pharmacokinetics and pharmacodynamics of single 
and multiple rising intravenous doses of BI 655130
Methodology:
Multiple rising dose: double-blind, randomised, placebo-controlled within dose 
groups
Single dose: single blind, partially randomised, placebo controlled
No. of subjects: 
total entered:
40
each treatment:
8 per dose group* (6 on active drug and 2 on placebo)
* Additional subjects may be entered to allow for testing of intermediate doses on the basis of 
experience gained during the trial conduct (e.g. preliminary PK data), provided the planned and 
approved highest dose will not be exceeded. Thus, the actual number of subjects entered may 
be increased, but will not exceed 48 subjects. 
Diagnosis:
Not applicable
Main criteria
for inclusion:
Healthy male subjects, age of 18 to 50 years, body mass index (BMI) of 18.5 to 
29.9 kg/m²

Criteria for safety:
Primary endpoint to assess safety and tolerability of BI 655130 is the number [N (%)] 
of subjects with drug-related adverse events (AEs).
Further criteria of interest:
Physical examination, vital signs (BP, PR, body temperature, continuous cardio-
monitoring), 12-lead ECG, laboratory tests (including haematology, clinical 
chemistry, urinalysis, coagulation parameters, cytokines and ADA), adverse events 
and local tolerability.
Statistical methods:
Descriptive statistics will be calculated for all endpoints.
Dose proportionality of BI 655130 will be explored using a regression model. A 95% 
confidence interval (CI) for the slope will be computed.
Linearity index will be estimated using a linear model providing a two-sided 95% CI.
Attainment of steady state will be analysed by a repeated measures linear model for 
trough concentrations of BI 655130 with dose as an additional covariate if 
permissible.

1.
Screening with subject information, informed consent as the first measure, includes physical examination, check 
of vital signs, ECG, safety laboratory (under fasting conditions), drug screening, demographics (including 
determination of body height and weight, smoking and alcohol history), relevant medical history, concomitant 
therapy and review of inclusion/exclusion criteria. 
2.
The time is approximate; procedures are to be performed and completed within 3 h prior to drug administration. 
Within 3 hours prior to the planned dosing, planned time -2:00 will be used. 
3.
Laboratory tests (safety laboratory) include clinical chemistry, haematology, coagulation and urinalysis; in 
addition at screening: serology (HBV, HCV, HIV), and drug screening.
4.
PK and PD sampling times may be adapted based on information obtained during trial conduct.
5.
Triple ECG
6.
Local tolerability inclusive.
7.
If several actions are indicated at the same time point, the intake of meals will be the last action.
8.
Confirmation of fitness includes physical examination.
9.
ADAs samples will be taken at baseline, Day 8, Day 15, Day 22, Day 29, Day 43, Day 57, Day 78, Day 92, Day 
120, Day 148 and Day 176 (EOT).
10. The cytokines IL1, IL6, TNF-and IFNwill be collected at baseline, 4h and 24h postdose after each of the 4 
single infusions. These samples are only to be analyzed in case of specific adverse events occur that are
suggestive for a cytokine release.
11. Only drug screening.
12. AEs and concomitant therapies will be recorded throughout the trial, but will be specifically asked for at the time 
points indicated in the Flow Chart above.
13. EOT (End of trial examination) includes physical examination, body weight, vital signs, ECG, safety laboratory, 
recording of AEs and concomitant therapies. EOT to be performed not before last PK sampling. 
14. Safety laboratory is to be taken within three days prior to study drug administration and can be omitted, if the 
screening examination is performed between Day -5 to Day -3.
15. First measure after completion of infusion is collection of PK and PD sample
16. In case plasma levels still exceed LOQ additional PK and ADA samples may be collected beyond Day 176

1.
Screening with subject information, informed consent as the first measure, includes physical examination, check 
of vital signs, ECG, safety laboratory (under fasting conditions), drug screening, demographics (including 
determination of body height and weight, smoking and alcohol history), relevant medical history, concomitant 
therapy and review of inclusion/exclusion criteria. 
2.
The time is approximate; procedures are to be performed and completed within 3 h prior to drug administration. 
Within 3 hours prior to the planned dosing, planned time -2:00 will be used. 
3.
Laboratory tests (safety laboratory) include clinical chemistry, haematology, coagulation and urinalysis; in 
addition at screening: serology (HBV, HCV, HIV), and drug screening.
4.
PK and PD sampling times may be adapted based on information obtained during trial conduct.
5.
Triple ECG
6.
Local tolerability inclusive.
7.
If several actions are indicated at the same time point, the intake of meals will be the last action.
8.
Confirmation of fitness includes physical examination.
9.
ADAs samples will be taken at baseline, Day 8, Day 15, Day 22, Day 29, Day 43, Day 57, Day 78, Day 92, Day 
120, Day 148 and Day 176 (EOT).
10. The cytokines IL1, IL6, TNF-and IFNwill be collected at baseline, 4h and 24h postdose after each of the 4 
single infusions. These samples are only to be analyzed in case of specific adverse events occur that are
suggestive for a cytokine release.
11. Only drug screening.
12. AEs and concomitant therapies will be recorded throughout the trial, but will be specifically asked for at the time 
points indicated in the Flow Chart above.
13. EOT (End of trial examination) includes physical examination, body weight, vital signs, ECG, safety laboratory, 
recording of AEs and concomitant therapies. EOT to be performed not before last PK sampling. 
14. Safety laboratory is to be taken within three days prior to study drug administration and can be omitted, if the 
screening examination is performed between Day -5 to Day -3.
15. First measure after completion of infusion collection of PK and PD sample
16. In case plasma levels still exceed LOQ additional PK and ADA samples may be collected beyond Day 176

1.
Screening with subject information, informed consent as the first measure, includes physical examination, check 
of vital signs, ECG, safety laboratory (under fasting conditions), drug screening, demographics (including 
determination of body height and weight, smoking and alcohol history), relevant medical history, concomitant 
therapy and review of inclusion/exclusion criteria. 
2.
The time is approximate; procedures are to be performed and completed within 3 h prior to drug administration. 
Within 3 hours prior to the planned dosing, planned time -2:00 will be used. 
3.
Laboratory tests (safety laboratory) include clinical chemistry, haematology, coagulation and urinalysis; in 
addition at screening: serology (HBV, HCV, HIV), and drug screening.
4.
PK and PD sampling times may be adapted based on information obtained during trial conduct.
5.
Triple ECG
6.
Local tolerability inclusive.
7.
If several actions are indicated at the same time point, the intake of meals will be the last action.
8.
Confirmation of fitness includes physical examination.
9.
ADAs samples will be taken at baseline, Day 8, Day 15, Day 22, Day 29, Day 43, Day 57, Day 78, Day 92, Day 
120, Day 148 and Day 176 (EOT).
10. At baseline of each dosing day, cytokines (IL1, IL6, TNF-and IFNsamples will be collected together with 
safety lab. Additional cytokines samples IL1, IL6, TNF-and IFNwill be collected at 4h and 24h post-dose
after each of the 4 single infusions. Cytokines samples are only to be analysed from an individual subject in case 
of specific adverse events in this subject that are suggestive for a cytokine release. At 4h and 24h post-dose no 
safety lab needs to be taken.
11. Only drug screening.
12. AEs and concomitant therapies will be recorded throughout the trial, but will be specifically asked for at the time 
points indicated in the Flow Chart above.
13. EOT (End of trial examination) includes physical examination, body weight, vital signs, ECG, safety laboratory, 
recording of AEs and concomitant therapies. EOT to be performed not before last PK sampling. 
14. Safety laboratory is to be taken within three days prior to study drug administration and can be omitted, if the 
screening examination is performed between Day -5 to Day -3.
15. First measure after completion of infusion collection of PK and PD sample
16. In case plasma levels still exceed LOQ additional PK and ADA samples may be collected beyond Day 176

2.2
TRIAL OBJECTIVES
The primary objective of this trial is to investigate the safety and tolerability of BI 655130 in 
healthy male subjects following IV administration of multiple rising doses of 3 mg/kg, 6 
mg/kg and 10 mg/kg b.w.. The study will also explore safety and tolerability following a 
single IV administration of 20 mg/kg b.w.. In case previous doses were shown to be safe and 
well tolerated multiple doses of 20 mg/kg may be studied as well to provide a further safety 
window to potential therapeutic doses in patients.
Secondary objectives are the exploration of the pharmacokinetics of BI 655130 after single 
and multiple IV administration.
A further objective is the exploration of pharmacodynamics and the evaluation of additional 
pharmacokinetic parameters beyond those already covered in secondary objectives.
A description of the endpoints to be determined, and the observations along with specific 
information as how to collect the data for that information, is provided in Section 5.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The multiple-rising dose part of the trial is designed as double-blind, randomised, and 
placebo-controlled within parallel dose group. The placebo-controlled single dose part will be 
conducted single-blind and partially randomised.
A total of 40 healthy male subjects is planned to participate in the trial, according to 5
sequential groups comprising 8 subjects per group. However, additional subjects may be 
entered to allow testing of additional intermediate doses based on the basis of experience 
gained during the trial conduct (e.g. preliminary PK data), provided the planned and approved 
highest dose will not be exceeded. Thus, the actual number of subjects entered may exceed 
40, but will not exceed 48 subjects. Such changes may be implemented via non-substantial 
CTP Amendments.
Within each dose group, 6 subjects will receive the active drug and 2 will receive placebo. 
Only one dose is tested within each dose group. Each dose group of the MRD part up to 20
mg/kg b.w. (within 4 weeks single intravenous doses on Day 1, Day 8, Day 15, and Day 22) 
will consist of 2 cohorts (in each cohort 3 on active and one on placebo) which will be treated 
subsequently for safety reasons. Dose group 4 (single dose of 20 mg/kg of BI 655130 or 
placebo) will consist of 3 cohorts (see section 2.3).
The dose groups to be evaluated are outlined in Table 3.1: 1 below.

The dose groups will be investigated consecutively in ascending order of doses, maintaining a 
time interval of at least 14 days between the last drug administration in the previous dose 
group and the first drug administration of the subsequent dose group. The decision to proceed 
to the next dose group will be based upon the safety and tolerability data of the preceding 
dose groups. The next dose will only be given if, in the opinion of the investigator, no safety 
concerns arose in the preceding dose group (i.e. no dose-limiting events occurred) and if none 
of the pre-specified trial-specific stopping criteria were met (refer to Section 3.3.4.2).
A documented Safety Review must take place prior to each dose escalation. Furthermore, an 
unscheduled safety review meeting can be requested anytime for any reasonable cause by the 
Principal Investigator (or an authorised deputy) or the sponsor of the study, e.g. because of

any unforeseen adverse events. Dose escalation will only be permitted if no safety concerns 
exist in the opinion of the Principal Investigator (or an authorised deputy) and the trial 
clinical monitor (or an authorised deputy). In addition, at least 6 evaluable subjects per dose 
level are required to decide about dose escalation to the next higher dose level.
The minimum data set for review consists of the following data:

AEs in the current and preceding dose groups (including clinically relevant findings 
from ancillary safety testing listed below) (Note: AEs may be ongoing at the time of 
Safety Reviews and AE information may be subject to change prior to Database Lock)

Results from 12-lead ECG and continuous ECG monitoring in the current and 
preceding dose groups.

Vital signs in the current and preceding dose groups

Clinical laboratory tests in the current and preceding dose groups

Check of criteria for stopping subject treatment as per Section 3.3.4.1
The decision to escalate the dose will be made jointly by the Principal Investigator (or an 
authorised deputy) and the trial clinical monitor (or an authorised deputy) after in-depth 
analysis of all available safety data, especially SAEs (if occurred), AEs and out-of-range 
laboratory results (if considered clinically significant). Safety Reviews can be conducted 
face-to-face or by video/telephone conference. The trial clinical monitor is responsible for 
organization and minutes of the reviews. Minutes will be signed off by the Principal 
Investigator (or an authorised deputy) and filed in the ISF and TMF.
The investigator (after consultation with the sponsor) is allowed to alter the scheduled dose 
levels (e.g. add low and/or intermediate dose levels) on the basis of experience gained during 
the study, provided the planned and approved highest dose is not exceeded. In this case, the 
total number of subjects in this trial might increase. The investigator and/or the sponsor 
should stop further dosing in case the safety evaluation leads to concerns that would not 
allow further dosing.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedules 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.
3.1.1

Tasks and functions assigned in order to organise, manage, and evaluate the trial are defined 
according to BI SOPs. A list of responsible persons and relevant local information can be 
found in the ISF.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
For multiple-rising dose trials, the design described in Section 3.1 is viewed favourable under 
the provision not to expose the subjects involved to undue risks since the main study 
objective is to investigate safety and tolerability of BI 655130.
With the rising dose design, double-blind conditions regarding the subject’s treatment (active 
or placebo) are maintained within each dose group. However, the current dose level will be 
known to subjects and investigators. The disadvantage of this trial design is a possible 
observer bias with regard to the dose-depending effects as well as time effects, but it has the 
virtue of minimizing subject risk by sequentially studying ascending doses. As time-effects 
are expected to be small relative to the differences between the doses in the broad range 
investigated, unbiased comparisons between treatments can still be expected.

After completion of the second dose group of the multiple-rising dose part the single dose 
part (20 mg/kg b.w. dose group) will start, which is conducted single-blind and partially 
randomised. This design was selected because a single infusion of 20 mg/kg b.w. was not 
tested in the preceding FIH study (section 1.2).
Provided that infusions of BI 655130 were well tolerated in the preceding dose groups the 
study may continue with dose group 5 (multiple doses of 20 mg/kg).
It is standard in trials involving healthy volunteers to include a placebo group as control for 
the evaluation of safety, tolerability and pharmacodynamic effects. Each dose group consists 
of 8 subjects with 6 on active treatment, and 2 on placebo. The placebo control group 
includes all subjects of all dose groups treated with placebo. 6 subjects per active treatment 
group are in general considered as sufficient for the exploratory evaluation of 
pharmacokinetics.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 40 healthy male subjects will enter the study. The actual number of subjects 
entered may exceed the total of 40 if additional intermediate doses will be tested (see Section 
3.1). Thus, the actual number of subjects entered may be increased, but will not exceed 48
subjects. Subjects will be recruited from the volunteers' pool of the trial site.
Only male subjects will be included into the study because hitherto no data on reproductive 
toxicology are available.
A log of all subjects enrolled into the trial (i.e. having given informed consent) will be 
maintained in the ISF at the investigational site irrespective of whether they have been treated 
with investigational drug or not.
3.3.1
Main diagnosis for study entry 
The study will be performed in healthy subjects.
3.3.2
Inclusion criteria

3.3.4
Removal of subjects from therapy or assessments
3.3.4.1
Removal of individual subjects
An individual subject is to be removed from the trial if:
1. The subject withdraws consent for trial treatment or trial participation, without the need to 
justify the decision
2. The subject needs to take concomitant drugs that interfere with the investigational  
product or other trial medication
3. The subject is no longer able to participate for other medical reasons (such as surgery, 
adverse events, or diseases)
4. An AE or clinically significant laboratory change or abnormality occurred that the 
investigator judges to warrant discontinuation of treatment. This may include cases of 
sustained symptomatic hypotension (BP <90/50 mmHg) or hypertension (BP >180/100 
mmHg) or of clinically relevant changes in ECG requiring intervention as well as 
unexplained liver enzyme elevations at any time during the trial.
5. The subject shows an elevation of AST and/or ALT ≥3-fold ULN combined with an 
elevation of total bilirubin ≥2-fold ULN (measured in the same blood sample) and/or 
needs to be followed up according to Appendix 10.1 of this clinical trial protocol and the 
‘DILI checklist’ provided in the ISF.
In addition to these criteria, the physician may discontinue subjects at any time based on his 
or her clinical judgment.
Infusion reactions should also lead to the removal of an individual subject. However, in mild 
transient cases of infusion reactions (with clinical symptoms such as dizziness, headache,
nausea) requiring no treatment the clinical investigator may pause the infusion or continue
with a reduced infusion rate as described for other therapeutic proteins [P16-06636].
However, the overall infusion time (including time of discontinuation) must not exceed 45 
minutes for 3 mg/kg b.w. and 6 mg/kg b.w. multiple dose and 90 minutes for 10 mg/kg b.w. 
multiple dose and 20 mg/kg b.w. single dose and 120 minutes for 20 mg/kg b.w. multiple 
dose.
A subject can also be removed from the trial if eligibility criteria are being violated or if the 
subject fails to comply with the protocol (for instance, by non-adherence to dietary rules, or 
non-attendance at study assessments).
If a subject is removed from or withdraws from the trial prior to first administration of trial 
medication, the data of this subject will not be entered in the case report form (CRF) or trial 
database and will not be reported in the clinical trial report (CTR). If a subject is removed 
from or withdraws from the trial after first administration of trial medication, this will be 
documented and the reason for discontinuation must be recorded in the CRF. In this case, the 
data will be included in the CRF/trial database and will be reported in the CTR. At the time 
of discontinuation a complete end of trial examination will be performed if possible and the 
information will be recorded in the CRFs. If the discontinuation occurs before the end of the 
REP (see Section 5.2.2.2), the discontinued subject should if possible be questioned for AEs 
and concomitant therapies at or after the end of the REP in order to ascertain collection of

AEs and concomitant therapies throughout the REP, if not contrary to any consent 
withdrawal of the subject. These discontinuations will be discussed in the CTR.
3.3.4.2
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial overall or at a particular trial 
site at any time for any of the following reasons:
1. New toxicological findings or serious adverse events invalidate the earlier positive 
benefit-risk-assessment. More specifically, the trial will be terminated if more than 50% 
of the subjects show drug-related and clinically relevant adverse events of moderate or 
severe intensity, or if at least one drug-related serious adverse event is reported that is
considered to be unacceptable.
2. The expected enrolment goals overall or at a particular trial site are not met
3. Violation of GCP, or the CTP, or the contract with BI by a trial site or investigator, 
disturbing the appropriate conduct of the trial
4. The sponsor decides to discontinue the further development of the investigational
product.
5. Dose escalation will be stopped as soon as at least 2 subjects at one dose level on active 
drug showed relevant individual QT prolongation, i.e. a QTc increase of greater 60 ms 
from baseline in connection with absolute QT or QTc greater than 500 ms, which has 
been confirmed by a repeat ECG recording.
The investigator / the trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except in case of the third reason).
3.3.5
Replacement of subjects
In case some subjects do not complete the trial, the trial clinical monitor together with the 
trial pharmacokineticist and the trial statistician are to decide if and how many subjects will 
be replaced. A replacement subject will be assigned a unique study subject number, and will 
be assigned to the same treatment as the subject
 replaces.

4.1.2
Method of assigning subjects to treatment groups
Prior to the screening visit, subjects will be contacted in writing and informed about the 
planned visit dates. The subjects willing to participate will be recruited to dose groups 
according to their temporal availability. As soon as enough subjects have been allocated to 1 
of the 11 dose cohorts (2 cohorts per dose group in the MRD part, 3 cohorts in the SRD part), 
the following subjects will be allocated to one of the other dose cohorts. Therefore, the 
allocation of subjects to dose cohorts is not influenced by trial personnel, but only by the 
subjects’ temporal availability. As the study includes healthy subjects from a homogenous 
population, relevant imbalances between the dose groups are not expected.
The randomisation list with study subject numbers and allocated treatments (SRD part) and 
the list of subject and medication numbers (MRD part) will be provided to the trial site in 
advance. The allocation of subjects to study subject numbers will be performed prior to the 
first administration of trial medication. For this purpose, the subjects will be allocated to a 
study subject number by drawing lots. Once a subject number has been assigned, it cannot be 
reassigned to any other subject.
The randomisation procedure is described in Section 7.5.
4.1.3
Selection of doses in the trial
The doses selected for this trial cover the subtherapeutic as well as the estimated therapeutic 
range and include a safety margin (see Section 1.2).
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. The dose volume for 
placebo corresponds to the dose volume of the respective dose level. For further details 
concerning timing see Flow Chart. Start and time of the infusion will be recorded.
Detailed instructions for the dilution of the trial product, the preparation of the infusion 
solution, the volume to be administered and the infusion rate is provided in Appendix 10.2. In 
all subjects the infusion solution will be intravenously administered over 30 minutes for dose 
group 3 mg/kg b.w. multiple dose and 6 mg/kg b.w. multiple dose and over 60 minutes for 
dose group 10 mg/kg b.w. multiple dose and 20 mg/kg b.w. single dose approximately 
between 8.00 h and 10.30 h of the respective study day. Multiple doses of 20 mg/kg b.w. will 
be administered over 90 minutes between 8.00 h and 12.00 h of the respective study day.
In case of safety concerns, e.g. due to infusion reactions, it is in the discretion of the 
investigator or his/her designee to adapt the infusion scheme, including but not limited 
slowing down the infusion rate, stopping of the infusion and provided no further safety 
concern exist restarting at a slower rate. Further based on 
 medical judgment he/she will 
provide medications such as steroids, etc. as needed.
For administration of the infusion, an intravenous indwelling catheter is placed into an arm 
vein of the subject and will be kept patent with a saline infusion. A second indwelling 
catheter used for collection of blood samples will be placed on the contralateral arm.
The administration of the trial medication on all study days will be done under supervision of 
the investigating physician or a designee. The so-called four-eye principle (two-person rule)

repeated doses (dose group 1 to 3) , from 2 hours post-dose, liquid intake is restricted at 
additional 3000 mL until the morning of Day 2. Standardised meals will be served as outlined 
in the Flow Chart. Subjects will be kept under close medical surveillance until 48 h following 
drug administration. Thereafter subjects will be discharged from the CPU and further 
assessments will be conducted in an ambulatory fashion. For restrictions with regard to diet 
see also Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
4.1.5.1
Blinding
For the MRD part, the trial is designed double-blind with regard to the subjects and the 
investigators (as well as the research staff at the trial site) in order to eliminate observer or 
performance bias. This means avoiding systematic differences in assessments regarding the 
subject’s treatment (active or placebo). 
The administration of the 20 mg single dose (active or placebo) will be single-blind (to assure 
single-blind conditions, subjects will not be informed about treatment assignment on the 
study days, i.e. subjects will not be aware that the second cohort of each dose level will only 
receive active treatment). 
According to the rising dose design, the current dose level will be known to subjects and 
investigators.
At the trial site, access to the randomisation schedule is restricted to unblinded pharmacists, 
pharmacy staff members or staff who will reconstitute the drug solution. Access to the codes 
will be controlled and documented by a signed confidentiality statement, which will be stored

in the TMF. Persons directly involved in the clinical conduct of the trial will not have access 
to the treatment allocation prior to database lock.
Within the ECG laboratory, the staff involved with interval measurements and assessments 
will be blinded for the MRD part and unblinded for the SRD part with respect to the 
treatment and also with regard to the recording date and time as well as the time points of the 
ECGs. The interval measurements for a given subject will be performed in a random and 
blinded sequence by a single technician. No more than two different blinded readers will 
evaluate the ECGs of the study.
In addition, the trial bioanalyst will request the randomisation codes prior to official 
unblinding to perform the interim / preliminary PK analysis. He or she will confirm in writing 
that the codes will be treated confidentially.
Regarding the sponsor, the database of this trial will be handled open-label, meaning that the 
trial functions of the sponsor are unblinded (including clinical monitor, data manager, 
statistician, bioanalyst, pharmacokineticist, pharmacometrician, drug metabolism scientist as 
well as dedicated CRO personnel). The objective of the trial is not expected to be affected.
4.1.5.2
Procedures for emergency unblinding
For blinded trials, the investigator will be supplied with a set of sealed envelopes containing 
the medication codes for each subject according to the randomisation scheme. The envelopes 
will be kept unopened at the trial site until the end of data collection. An envelope may only 
be opened in emergency situations when the identity of the trial drug must be known to the 
investigator in order to provide appropriate medical treatment or to assure safety of trial 
participants. If the envelope for a subject is opened, the sponsor must be informed 
immediately. The reason for opening the code break must be documented on the envelope or 
appropriate CRF page along with the date and the initials of the person who broke the code. 
At the close-out visit all envelopes are collected.
4.1.6
Packaging, labelling, and re-supply
Drug supplies will be provided by the Department of Pharmaceutical Development of 
Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach, Germany.
The clinical trial supply consists of containers holding the trial medication which are labelled 
with trial identification. The required information according to Annex 13/EU GMP Guideline 
will be provided on the containers. Smaller boxes within the clinical trial supply containers 
will be labelled with:

BI trial number

Name of product and strengths or identification code

Pharmaceutical dosage form, quantity of dosage units 

Route and mode of administration

Term ‘For Clinical Trial Use’ (domestic language)


Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area according to the recommended (labelled) storage conditions. Where necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be immediately contacted.
4.1.8
Drug accountability
The investigator / pharmacist / investigational drug storage manager will receive the 
investigational drugs delivered by the sponsor when the following requirements are fulfilled:

Approval of the study protocol by the IRB / ethics committee

Availability of a signed and dated clinical trial contract between the sponsor and the 
Head of Trial Centre

Approval/notification of the regulatory authority, e.g. competent authority

Availability of the curriculum vitae of the principal investigator

Availability of a signed and dated clinical trial protocol or immediately imminent 
signing of the clinical trial protocol 
Only authorised personnel as documented in the form ‘Site Delegation Log’ may dispense 
medication to trial subjects. The trial medication must be administered in the manner 
specified in the CTP. All unused medication will be disposed locally by the trial site upon 
written authorization by the clinical monitor. Receipt, usage and disposal must be 
documented on the respective forms. Account must be given for any discrepancies. 
The investigator / pharmacist / investigational drug storage manager must maintain records of 
the product’s delivery to the trial site, the inventory at the site, the use by each subject, and 
the return to the sponsor or alternative disposal of unused products. 
These records will include dates, quantities, batch / serial numbers, expiry (‘use-by’) dates, 
and the unique code numbers assigned to the investigational products and trial subjects. The 
investigator / pharmacist / investigational drug storage manager will maintain records that 
document adequately that the subjects were provided the doses specified by the CTP, and that 
reconcile all investigational products received from the sponsor. At the time of disposal, the

CONCOMITANT THERAPY, RESTRICTIONS, AND RESCUE 
TREATMENT
4.2.1
Rescue medication, emergency procedures, and additional treatments
There are no specific rescue drugs foreseen for the treatment of AEs. No special emergency 
procedures are to be followed. No additional treatment is planned. However, in case of 
adverse events in need of treatment, the investigator can authorise symptomatic therapy. In 
those cases, subjects will be treated as necessary and, if required, kept under supervision at 
the trial site or transferred to a hospital until all medical evaluation results have returned to an 
acceptable level.
4.2.2
Restrictions
4.2.2.1
Restrictions regarding concomitant treatment

12-lead ECG

Continuous ECG monitoring

Vital signs (blood pressure, pulse rate)

Assessment of adverse events
5.2.2.1
Definitions of adverse events
Adverse event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have 
to have a causal relationship with this treatment.
An AE can therefore be any unfavourable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
product, whether or not considered related to the medicinal product.
Adverse reaction
An adverse reaction is defined as a response to a medicinal product which is noxious and 
unintended. Response in this context means that a causal relationship between a medicinal 
product and an adverse event is at least a reasonable possibility. Adverse reactions may arise 
from use of the product within or outside the terms of the marketing authorisation or from 
occupational exposure. Conditions of use outside the marketing authorization include off-
label use, overdose, misuse, abuse and medication errors.

001-MCS-40-106-RD-11 (5.0) / Saved on: 25 Jun 2014
Serious adverse event
A serious adverse event (SAE) is defined as any AE which:

results in death, 

is life-threatening, this refers to an event in which the patient was at risk of death at 
the time of the event; it does not refer to an event that hypothetically might have 
caused death if more severe,

requires inpatient hospitalisation or prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity

is a congenital anomaly/birth defect, 
or 

is to be deemed serious for any other reason if it is an important medical event when 
based upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions.
Medical and scientific judgement should be exercised in deciding whether other situations 
should be considered serious reactions, such as important medical events that might not be 
immediately life threatening or result in death or hospitalisation but might jeopardise the 
patient or might require intervention to prevent one of the other outcomes listed above. 
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalisation or 
development of dependency or abuse. Any suspected transmission via a medicinal product of 
an infectious agent is also considered a serious adverse reaction.
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be reported as a serious 
event regardless of the duration between discontinuation of the drug and the occurrence of the 
cancer.
In accordance with the European Medicines Agency initiative on Important Medical Events, 
Boehringer Ingelheim has set up a list of further AEs, which by their nature, can always be 
considered to be ‘serious’ even though they may not have met the criteria of an SAE as given 
above.
The latest list of ‘Always Serious AEs’ can be found in the RDC system. A copy of the latest 
list of ‘Always Serious AEs’ will be provided upon request. These events should always be 
reported as SAEs as described above.
Adverse events of special interest (AESIs)
The term AESI relates to any specific AE that has been identified at the project level as being 
of particular concern for prospective safety monitoring and safety assessment within this trial, 
e.g. the potential for AEs based on knowledge from other compounds in the same class. AESI 
need to be reported to the sponsor’s Pharmacovigilance Department within the same 
timeframe that applies to SAE, please see above.

001-MCS-40-106-RD-11 (5.0) / Saved on: 25 Jun 2014
The following are considered as AESIs in this trial:

Hepatic injury, as defined by the following alterations of hepatic laboratory 
parameters:
o
an elevation of AST and/or ALT ≥3-fold ULN combined with an elevation of 
total bilirubin ≥2-fold ULN measured in the same blood sample, and/or
o
marked peak aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN
These lab findings constitute a hepatic injury alert and the patients showing these lab 
abnormalities need to be followed up according to the ‘DILI checklist’ provided in the 
ISF. In case of clinical symptoms of hepatic injury (icterus, unexplained 
encephalopathy, unexplained coagulopathy, right upper quadrant abdominal pain, 
etc.) without lab results (ALT, AST, total bilirubin) available, the Investigator should 
make sure these parameters are analysed, if necessary in an unscheduled blood test. 
Should the results meet the criteria of hepatic injury alert, the procedures described in 
the DILI checklist should be followed.
Intensity of AEs
The intensity of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Enough discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
The definition of an adverse reaction implies at least a reasonable possibility of a causal 
relationship between a suspected medicinal product and an adverse event. An adverse 
reaction, in contrast to an adverse event, is characterised by the fact that a causal relationship 
between a medicinal product and an occurrence is suspected.
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
Arguments that may suggest that there is a reasonable possibility of a causal relationship 
could be:

The event is consistent with the known pharmacology of the drug 

The event is known to be caused by or attributed to the drug class.

A plausible time to onset of the event relative to the time of drug exposure.

Evidence that the event is reproducible when the drug is re-introduced

No medically sound alternative aetiologies that could explain the event (e.g. pre-
existing or concomitant diseases, or co-medications).

The event is typically drug-related and infrequent in the general population not 
exposed to drugs (e.g. Stevens-Johnson syndrome).


An indication of dose-response (i.e. greater effect size if the dose is increased, smaller 
effect size if dose is diminished).
Arguments that may suggest that there is no reasonable possibility of a causal relationship 
could be:

No plausible time to onset of the event relative to the time of drug exposure is evident 
(e.g. pre-treatment cases, diagnosis of cancer or chronic disease within days / weeks 
of drug administration; an allergic reaction weeks after discontinuation of the drug 
concerned)

Continuation of the event despite the withdrawal of the medication, taking into 
account the pharmacological properties of the compound (e.g. after 5 half-lives).
Of note, this criterion may not be applicable to events whose time course is prolonged 
despite removing the original trigger.

Additional arguments amongst those stated before, like alternative explanation (e.g. 
situations where other drugs or underlying diseases appear to provide a more likely 
explanation for the observed event than the drug concerned).

Disappearance of the event even though the study drug treatment continues or remains 
unchanged. 
5.2.2.2
Adverse event collection and reporting
AEs collection
Upon enrolment into a trial, the subject’s baseline condition is assessed (for instance, by 
documentation of medical history/concomitant diagnoses), and relevant changes from 
baseline are noted subsequently. 
Subjects will be required to report spontaneously any AEs as well as the time of onset, end, 
and intensity of these events. In addition, each subject will be regularly assessed by the 
medical staff throughout the clinical trial and whenever the investigator deems necessary. As 
a minimum, subjects will be questioned for AEs (and concomitant therapies) at the time 
points indicated in the Flow Chart. Assessment will be made using non-specific questions 
such as ‘How do you feel?’. Specific questions will be asked wherever necessary in order to 
more precisely describe an AE.
A careful written record of all AEs shall be kept by the investigator in charge of the trial. 
Records of AEs shall include data on the time of onset, end time, and intensity of the event as 
well as any treatment or action required for the event and its outcome.
The following must be collected and documented on the appropriate CRF(s) by the 
investigator:

From signing the informed consent onwards through the residual effect period (REP), 
until individual subject’s end of trial: 
o
All AEs (serious and non-serious) and all AESIs.
o
The only exception to this rule are AEs (serious and non-serious) and AESIs 
in Phase I trials in healthy volunteers, when subjects discontinue from the trial 
due to screening failures prior to administration of any trial medication. In

these cases, the subjects’ data must be collected at trial site but will not be 
entered in the CRF or trial database and will not be reported in the CTR.

After the individual subject’s end of trial: 
o
The investigator does not need to actively monitor the subject for AEs but 
should only report relevant SAEs and relevant AESIs of which 
 may 
become aware of.
The REP for BI 655130, when measurable drug levels or PD effects are still likely to be 
present after the last administration, is not known at this early stage of development. 
Therefore, all AEs reported until the end of trial examination will be considered on treatment;
please see Section 7.3.3.
The follow-up period describes the period of time from the last administration of trial 
medication including the REP until the end of trial examination (last per protocol visit).
AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form.
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information the same rules and timeline apply as for initial 
information.
Information required
For each AE, the investigator should provide the information requested on the appropriate 
CRF pages and the BI SAE form (if applicable). The investigator should determine the causal 
relationship to the trial medication. The following should also be recorded as an (S)AE in the 
CRF and on the SAE form (if applicable):

Worsening of the underlying disease or of other pre-existing conditions


Changes in vital signs, ECG, physical examination and laboratory test results, if they 
are judged clinically relevant by the investigator.
If such abnormalities already pre-exist prior trial inclusion they will be considered as 
baseline conditions.
All (S)AEs, including those persisting after individual subject’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.
5.2.3
Assessment of safety laboratory parameters
For the assessment of laboratory parameters, blood and urine samples will be collected by the 
trial site at the time points indicated in the Flow Chart after the subjects have fasted for at 
least 10 h. Overnight fasting is not required at the discretion of the investigator or designee
for retests.

The cytokines IL1, IL6, TNF-and IFNwill be collected at baseline, 4h and 24h postdose
after each infusion (for all subjects on Day 1, for subjects receiving multiple doses also on 
Day 8/9, Day 14/15 and Day 22/23. The cytokine samples will be only analyzed in case of 
specific adverse events suggestive for cytokine release.
5.2.4
Electrocardiogram
5.2.4.1
12-lead resting ECG
Twelve-lead resting ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a 
computerised electrocardiograph (MAC 5500, GE Healthcare) at the time points given in the 
Flow Chart.
In order to achieve a stable heart rate at rest and to assure high quality recordings at 
comparable resting phases, all ECGs will be recorded for a 10-sec duration after the subjects 
have rested for at least 5 min in a supine position. The site personnel will be instructed to 
assure a relaxed and quiet environment so that all subjects are at complete rest during the 
recordings. ECG assessment will always precede all other study procedures of the same time 
point (except blood drawing from an intravenous cannula which is already in place) to avoid 
impact of sampling on the ECG quality.
Electrode placement will be performed according to the method of Wilson, Goldberger and 
Einthoven.
Triple ECGs (recorded within 180 sec) will be recorded as the baseline before any drug 
administration part up to 48 h after dosing. At all other time points single ECGs will be 
recorded.
All locally printed ECGs will be evaluated by the investigator or a designee.
ECGs may be repeated for quality reasons (like alternating current artefacts, muscle 
movements, electrode dislocation). For time points with triple ECGs, all three single ECGs 
will be repeated. For the repeats due to quality reasons, only the repeated ECG recordings 
will be analyzed by the central ECG lab, whereas the initially recorded ECGs will be 
discarded. 
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
These ECGs are assigned to the prior scheduled time point. Unscheduled ECGs will not be 
included into the statistical analysis of interval lengths. 
For the inclusion or exclusion (see Section 3.3) of a subject and for the assessment of cardiac 
safety during the study, the QT and QTcB values generated by the ECG machines or their 
manual corrections by the investigators will be used. In doubtful cases, ECGs may be sent 
upfront for centralised evaluation (see below). In this case, these centrally measured results 
would overrule any other results obtained.
Abnormal findings will be reported as AEs (during the trial) or baseline conditions (at 
screening) if judged clinically relevant by the investigator. Any ECG abnormalities will be 
monitored carefully and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment.

In addition, a centralised evaluation of all 12-lead ECGs recorded from baseline up to 48 h 
after each dosing will be performed by an independent ECG laboratory. For this analysis, RR 
and QTall intervals will be determined semi-automatically, whereas PR and QRS intervals 
are determined by a validated GE 12-SL-algorithm or equivalent by the ECG core lab. Other 
parameters (e.g. cardiac axis) are determined by a validated GE 12-SL-algorithm or 
equivalent but do not undergo semi-automatic evaluation. For each QT interval, the RR 
interval preceding the QT will be measured to calculate the respective frequency corrected 
QTc intervals ‘QTcF’ according to Fridericia’s formula (QTcF = QT / RR1/3) and ‘QTcB’ 
according to Bazett’s formula (QTcB = QT / RR1/2). The QTcF correction will be used for 
evaluation and reporting. Abnormalities detected during centralised ECG evaluation will not 
necessarily qualify as AE. All interval measurements in one subject will be performed on the 
same lead. The intervals will be measured from four cardiac cycles (beats) in lead II. If lead 
II shows a flat T wave or is not measurable for any reason, lead V5 will be used, or if that 
lead is not measurable, then lead I will be used. The lead actually used will be reported in the 
CTR.
Within the ECG laboratory, the staff involved with ECG interval measurements and 
assessments will be blinded with regard to treatment, date and time as well as time points of 
the ECG measurements. The interval measurements for a given subject will be performed in 
random sequence by a single technician. No more than two different blinded readers will 
evaluate all ECGs of the study. For quality assurance and control of the measurements, all 
ECGs of a subject will be subsequently reviewed by the ECG technician supervisor or his/her 
designee with respect to the overall variance of the measured intervals, in order to detect 
accidentally switching of leads and/or false subject assignments of the ECGs. After the 
quality control the fiducial point markings will be reviewed by the cardiologist assigned to 
the study.
Assessed ECGs will comply with the ICH E14 guidance document and supplements 
[R05-2311], [R13-0801], [R13-4095] as well as the FDA requirements for annotated digital 
ECGs [R09-4830].
5.2.4.2
Continuous ECG monitoring and oxygen monitoring
Cardiac rhythm (including heart rate) will be monitored by means of continuous 2-lead ECG 
recording for at least 15 min before (for baseline assessment) and 2 h following start of 
infusion using the Dräger Telemetry monitoring system, Infinity M300. Oxygen saturation 
will be monitored by pulse oximetry using either Type NT1 handheld pulse oximeter from 
Newtech or Oxytrue A from Bluepoint Medical.

Vital signs
Systolic and diastolic blood pressures (BP) as well as pulse rate (PR) or heart rate (heart rate 
is considered to be equal to pulse rate in healthy volunteers) will be measured by a blood 
pressure monitor (Welch Allyn 530TP and 530TO devices) at the times indicated in the Flow 
Chart, after subjects have rested for at least 5 min in a supine position. All recordings should

All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine pharmacokinetic and 
pharmacodynamic parameters in an appropriate way. The scheduled measurements will allow 
monitoring of changes in vital signs, standard laboratory values, and ECG parameters that 
might occur as a result of administration of trial medication. The safety assessments are 
standard, are accepted for evaluation of safety and tolerability of an orally administered drug, 
and are widely used in clinical trials. The pharmacokinetic parameters and measurements 
outlined in Section 5.5 are generally used assessments of drug exposure. The biomarkers and

Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 655130 plasma concentrations, approximately 3.0 mL of blood will 
be taken from a forearm vein into a K2EDTA (ethylendiaminetetraacetic acid) anticoagulant 
blood-drawing tube at the time points listed in the Flow Chart under plasma PK. 
Mix the K2EDTA-anticoagulated blood samples gently and place on ice until centrifugation 
at about +4°C. The blood should be centrifuged to produce plasma as soon as possible after 
collection, but not later than 30 minutes after withdrawal. Centrifugation will last for 
approximately 10 minutes (at 2000 to 4000 x g) at about +4°C. Two aliquots of EDTA 
plasma sample will be obtained in two labelled polypropylene cryotubes. At a minimum, the 
sample tube labels should list the following information: BI trial number, subject number, 
visit, PTM, aliquot #1 or #2, plasma and PK. 
The two aliquots should contain approximately 0.5 mL of plasma each. The plasma samples 
will be stored in a freezer set to -20°C or below at the clinical site(s) until shipment on dry ice 
to the central lab (with dry ice sufficient for at least 3 days transit), then stored in a freezer set 
to -20°C or below at the site until shipment to the analytical laboratory. Both aliquots will be 
shipped (in separate shipments with dry ice sufficient for 3 days transit) to the analytical 
laboratory for the determination of BI 655130. Both aliquots will be stored in in a freezer set 
to -20°C or below at the analytical laboratory until the finalization of the clinical trial report.

After completion of the trial the plasma samples may be used for further methodological 
investigations, e.g. for stability testing. However, only data related to the analyte will be 
generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years after the final study 
report has been signed.
5.5.2.2
Plasma sampling for ADA assessment 
For ADA assessment, approximately 3.0 mL of blood will be taken from a forearm vein into 
a K2EDTA anticoagulant blood-drawing tube at the time points listed in the Flow Chart
under plasma ADA. 
Mix the K2EDTA-anticoagulated blood samples gently and place on ice until centrifugation 
at approximately +4°C. The blood should be centrifuged to produce plasma as soon as 
possible after collection, but not later than 30 minutes after withdrawal. Centrifugation will 
last for approximately 10 minutes (at 2000 to 4000 x g) at approximately +4°C. Two aliquots 
of EDTA plasma samples will be obtained in two labelled (label to include: trial number, 
subject number, visit, PTM, aliquot #1 or #2, plasma, and ADA) polypropylene cryotubes. 
The two aliquots should contain approximately 0.5 mL of plasma each. The plasma samples 
will be stored in a freezer set to -20°C or below at the clinical site(s) until shipment on dry ice 
to the central lab (with dry ice sufficient for at least 3 days transit), then stored in a freezer set 
to -20°C or below at the central lab until shipment to the analytical laboratory. Both aliquots 
will be shipped (in separate shipments with dry ice sufficient for 3 days transit) to the 
analytical laboratory for assessment of potential ADA to BI 655130. Once received at the 
analytical laboratory, both aliquots will be stored in in a freezer set to -20°C or below.
After completion of the trial the plasma samples may be used for further methodological 
investigations, e.g. for stability testing. However, only data related to the anti-drug antibodies
will be generated by these additional investigations. The study samples will be discarded after 
completion of the additional investigations but not later than 5 years upon the final study 
report has been signed.
5.5.3
Analytical determinations
5.5.3.1
Analytical determination of BI 655130 plasma concentration
BI 655130 concentrations will be determined by a validated Gyros affinity flow-through 
immunoassay. Analyses will be performed at QPS in Newark, DE 19711, USA.
5.5.3.2
Assessment of ADA to BI 655130
The presence of ADA to BI 655130 will be assessed via their detection using a validated 
immunoassay in a tiered approach (screening, confirmatory, and titration analysis as 
appropriate). Analyses will be performed at Charles River Laboratories, US.

Single/multiple dose part
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs and 12-
lead ECG recordings have to be done first. Furthermore, if several measurements including 
venipuncture are scheduled for the same time, venipuncture should be the last of the 
measurements due to its inconvenience to the subject and possible influence on physiological 
parameters.
For planned individual plasma concentration sampling times refer to the Flow Chart. While 
these nominal times should be adhered to as closely as possible, the actual sampling times 
will be recorded and used for determination of pharmacokinetic parameter.
If a subject misses an appointment, it will be rescheduled if possible. The relevance of 
measurements outside the permitted time windows will be assessed no later than at the 
Blinded Report Planning Meeting.

6.2.3
End of trial and follow-up period
For AE assessment, laboratory tests, collection of PK and ADA samples, recording of ECG 
and vital signs, and physical examination during the end of trial period, see Sections 5.2.2 to 
5.2.5.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the end of trial visit.
All abnormal values (including laboratory parameters) that are judged clinically relevant by 
the investigator will be monitored using the appropriate tests until a return to a medically 
acceptable level is achieved. Adverse events persisting after trial completion must be 
monitored until they have normalised or have been sufficiently characterised. 
The end of the trial as a whole is defined by the ‘last regular visit completed by last subject’ 
or ‘end date of the last open AE’ or ‘date of the last follow-up test’ or ‘date of an AE has 
been decided as sufficiently followed-up’, whichever is latest.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
7.1.1
Objectives
The primary objective of this trial is to investigate the safety and tolerability of BI 655130 by 
using descriptive statistics for all endpoints comparing active dose groups to placebo in 
healthy male subjects. The study will also explore safety and tolerability following a single 
IV administration of 20 mg/kg b.w. The primary endpoint is defined in Section 5.2.1. 
Inferential statistics is not planned (as explained in Section 7.2).
Secondary objectives are the exploration of the pharmacokinetics of BI 655130 after single 
and multiple IV administration.
A further objective is the exploration of pharmacodynamics and the evaluation of additional 
pharmacokinetic parameters beyond those already covered in secondary objectives.
The secondary objective is the exploration of the pharmacokinetics (PK) and 
pharmacodynamics (PD) of BI 655130. Endpoints as specified in 5.5.1 and 5.7.1 will be 
analysed by descriptive statistics. Secondary endpoints as defined in Section 5.5.1.1 will be 
subjected to analysis of dose proportionality by use of the power model. Trough
concentration values will be analysed regarding attainment of steady state as a pre-requisite 
for calculation of steady state parameters. Additionally, the linearity index will be estimated. 
7.2
NULL AND ALTERNATIVE HYPOTHESES
Safety and tolerability of 5 different dose groups of BI 655130 (Section 3.1) are to be 
determined on the basis of the investigated parameters in comparison to placebo. It is not 
planned to test any statistical hypotheses with regard to these variables in a confirmatory 
sense. Instead, they will be described in their entirety and evaluated by descriptive statistical 
methods.
Confidence intervals will be computed and will have to be interpreted in the perspective of 
the exploratory character of the study, i.e. confidence intervals are considered as interval 
estimates for effects.
7.3
PLANNED ANALYSES
All individual data will be listed.
Adherence to the protocol (such as inclusion/exclusion criteria, times of measurement, 
compliance with intake of trial medication, treatment dispensing errors, prohibited 
concomitant medication, completeness and consistency of data) will be checked. Important 
protocol violations (IPVs) will be identified no later than in the Blinded Report Planning 
Meeting and provided in the TSAP.

7.3.1
Primary analyses
Analysis of safety and tolerability is described in Section 7.3.3.
7.3.2
Secondary analyses
The secondary parameters (refer to Section 5.5.1) will be calculated according to the BI 
Standard Operating Procedure (SOP) ‘Standards and processes for analyses performed within 
Clinical Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472). Analyses will be 
performed for parent drug.
Pharmacokinetic parameters of a subject will be included in the analysis unless the subject 
has an important protocol violation relevant for the evaluation. Whether a protocol violation 
is important will be decided no later than in the Blinded Report Planning Meeting. 
Reasons for exclusion of single pharmacokinetic parameters may be:

The subject experiences emesis at or before two times median tmax. Median tmax is to 
be determined for the test product excluding the subjects experiencing emesis.

The subject experiences emesis at any time during the labelled dosing interval.

Time deviations

Use of restricted medications 
The subject set for the evaluation of PK endpoints (PKS) will include all treated subjects that 
provide at least one observation for at least one secondary endpoint without important 
protocol violations with respect to the statistical evaluation of PK endpoints. It will be 
decided in the Blinded Report Planning Meeting which subjects are to be included in the 
PKS.
Excluded subjects will be listed with their individual plasma concentrations and individual 
pharmacokinetic parameters, however, will not be included in descriptive statistics for plasma 
concentrations, pharmacokinetic parameters or other statistical assessment.
Assessment of dose proportionality
Dose proportionality will be assessed using the pharmacokinetic endpoints as specified in 
5.5.1.1.
The basic model for the investigation of dose proportionality will be a power model that 
describes the functional relationship between the dose and PK endpoints.

Based on the estimate for slope parameter (β), a 2-sided 95% CI for the slope will be 
computed. Perfect dose proportionality would correspond to a slope of 1. The assumption of a 
linear relationship between the log-transformed pharmacokinetic endpoint and the log-
transformed dose will be checked.
If dose proportionality over the entire dose range investigated cannot be shown, an attempt 
will be made to identify dose range(s), where dose proportionality can be assumed.

Linearity with respect to multiple administration will be explored using the linearity index 
(LI) that will be computed as follows:

In order to construct a confidence interval for LI, a statistical model using AUCτ,ss  and  AUC

will then be performed including calculation of a 2-sided 95% CI. The back transformed 
point estimate then represents the estimate of  LI. Perfect linearity with respect to multiple 
administrations holds true if this index equals unity.
Generally, this model will be applied to each dose level separately. If there is evidence that 
the areas are comparable across dose levels, they can be analysed simultaneously. The 
corresponding model will then include the log transformed dose as (additional) covariate
Attainment of steady state
Attainment of steady state will be explored for the three dose-groups undergoing multiple 
dose administrations by using the trough concentrations of BI 655130 between days 4 and 22
and the concentrations taken directly at the end of the first and the last dosing interval (Cτ,1, 
Cτ,22) for each dose level. Pairwise comparisons of concentrations are performed using 2-
sided 95% CIs based on the t-distribution. The calculation is based on a repeated measures 
linear model on the logarithmic scale.

random error associated with subject j at time i (assumed to be independent
and identically normally distributed).
Dose can be included as an additional covariate if there is evidence that the trough 
concentration profiles are comparable across dose levels.
The model will be used to explore the time to steady state by pairwise comparing 
concentrations from different time points: log-transformed differences between all 
subsequent time points (log(Cpre,i/Cpre,j) = log(Cpre,i) - log(Cpre,j), where j>i) will be compared 
and adjusted means (Least Squares Means) as well as 2-sided 95% CIs will be calculated. 
Thereafter, these quantities will be back-transformed by exponentiation to give the 
corresponding (adjusted) ratio and CI.
Comparisons which reveal CIs (for the adjusted ratio) not including 100% will be inspected 
to determine if the differences between time points are resulting from not yet attaining 
steady-state. 
For further details refer to the TSAP (such as selection of covariance structure and 
comparison of time points).

Investigation of relative bioavailability for single i.v. dose of 20 mg/kg weight
The investigation of relative bioavailability will be done on the secondary pharmacokinetic 
endpoints listed in Section 5.5.1.1 for the 20 mg/kg of weight dose group. 
The statistical model used for the analysis of relative bioavailability of BI 655130 will be an 
ANOVA (analysis of variance) model on the logarithmic scale.
7.3.3
Safety analyses
Safety will be assessed for the endpoints listed in Section 5.2.1. All treated subjects (that is,
all subjects who received at least one dose of study drug), will be included in the safety 
evaluation. Safety analyses will be descriptive in nature and will be based on BI standards.
Treatments will be compared in a descriptive way. The placebo control group in the safety 
evaluation will consist of all placebo treated subjects, regardless of the dose group in which 
they were treated. The active treatment groups will be compared to the placebo group in a 
descriptive way. Tabulations of frequencies/proportions will be used for the evaluation of 
categorical (qualitative) data, and tabulations of descriptive statistics will be used to analyse 
continuous (quantitative) data. Separate listings will be provided for subjects under multiple 
drug administration and the ones with a single dose of 20 mg/kg.
The analyses will be done by ‘treatment at onset’. 
Measurements (such as ECG, vital signs, or laboratory parameters) or AEs will be assigned to 
treatments (see Section 4.1) based on the actual treatment at the planned time of the 
measurement or on the recorded time of AE onset (concept of treatment emergent AEs). 
Therefore, measurements planned or AEs recorded prior to first intake of trial medication will 
be assigned to 'screening', those between first trial medication intake until the end of trial visit 
will be assigned to the treatment period, and those after the end of trial examination will be 
assigned to ‘post-study’. These assignments including the corresponding time intervals will 
be defined in detail in the TSAP.
Additionally, further treatment intervals (analysing treatments) may be defined in order to 
provide summary statistics for time intervals, such as combined treatments, on-treatment 
totals or periods without treatment effects (such as screening and post-study intervals).
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA). Frequency, intensity and causal relationship of AEs will be tabulated by 
treatment, primary system organ class and preferred term. SAEs, AESIs (see Section 5.2.2.1) 
and other significant AEs (according to ICH E3) will be listed separately. 
Laboratory data will be compared to their reference ranges. Values outside the reference 
range will be flagged. Additionally, differences from baseline will be evaluated.
For vital signs, the differences from baseline will be evaluated.
A centralised evaluation of all 12-lead ECGs recordings (see Section 5.2.4) will be the basis 
for the derivation of further ECG parameters based on the ECG variables QT, HR, QTcF, 
QTcB, PR, QRS, and RR. The baseline value of an ECG variable is defined as the mean of 
the triple ECG measurements prior to drug administration. The derivation of the quantitative 
and qualitative ECG endpoints and their analyses will be described in the TSAP.

7.3.4
Interim analyses
No interim analysis is planned.
7.3.5
Pharmacokinetic analyses
The pharmacokinetic parameters listed in Section 5.5.1 for drug BI 655130 will be calculated 
according to the BI SOP ‘Standards and processes for analyses performed within Clinical 
Pharmacokinetics/Pharmacodynamics’ (001-MCS-36-472).
Subjects who are not included in the PKS (refer to Section 7.3.1.) will be reported with their 
individual plasma and individual pharmacokinetic parameters; however, they will not be 
included in descriptive statistics for plasma, pharmacokinetic parameters or other statistical 
assessment.
Only concentration values within the validated concentration range and actual sampling times 
will be used for the calculation of pharmacokinetic parameters. Concentrations used in the 
pharmacokinetic calculations will be in the same format provided in the bioanalytical report, 
(that is, to the same number of decimal places provided in the bioanalytical report).
If a predose concentration value is greater than 5% of Cmax, the subject’s pharmacokinetic 
data will be not included in any statistical evaluations, in accordance with international 
guidances. The individual pharmacokinetic parameters of such a subject will be calculated 
and listed separately. If a predose concentration is above BLQ, but less than or equal to 5% of 
the subject’s Cmax value, the subject’s data without any adjustments will be included in all 
pharmacokinetic measurements and calculations.

HANDLING OF MISSING DATA
7.4.1
Safety
With respect to safety evaluations, it is not planned to impute missing values.
7.4.2
Plasma/urine drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472).
Drug concentration data identified with NOS (no sample available), NOR (no valid result), 
NOA (not analysed), BLQ (below the lower limit of quantification), or NOP (no peak 
detectable) will be displayed as such and not replaced by zero at any time point (this rule also 
applies also to the lag phase, including the predose values). 
7.4.3
Pharmacokinetic parameters
Handling of missing PK data will be performed according to the relevant SOP of the Sponsor 
(001-MCS-36-472).
For the non-compartmental analysis, concentration data identified with NOS, NOR or NOA 
will generally not be considered. Concentration values in the lag phase identified as BLQ or 
NOP will be set to zero. All other BLQ/NOP values of the profile will be ignored. The lag 
phase is defined as the period between time zero and the first time point with a concentration 
above the quantification limit.
7.5
RANDOMISATION
Subjects will be randomised within each dose group in a 3:1 ratio, which reflects the ratio of 
subjects receiving active drug to placebo.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system, which
involves a pseudo-random number generator and a supplied seed number so that the resulting 
allocation is both reproducible and non-predictable.

The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.6
DETERMINATION OF SAMPLE SIZE
It is planned to include a total of 40 subjects in this trial. The planned sample size is not based 
on a power calculation. The size of 8 subjects per dose group (6 on active treatment, and 2 on 
placebo) is considered as sufficient for the exploratory evaluation of multiple dose safety and 
pharmacokinetics [R95-0013].
Additional subjects may be entered to allow testing of intermediate doses within the planned 
and approved dose range on the basis of experience gained during trial conduct (e.g. 
preliminary PK data), i.e. the actual number of subjects entered may exceed 40.

APPENDICES
10.1
CLINICAL EVALUATION OF LIVER INJURY
10.1.1
Introduction
Alterations of liver laboratory parameters, as described in Section 5.2.2.1 (Protocol-specified 
AESIs), are to be further evaluated using the following procedures:
10.1.2
Procedures
Repeat the following laboratory tests: ALT, AST, and bilirubin (total and direct) - within 48 
to 72 h. If it is confirmed that ALT and/or AST values ≥3 fold ULN occur in conjunction 
with an elevation of total bilirubin of ≥2 fold ULN, the laboratory parameters listed below 
(clinical chemistry, serology, hormones, haematology) must be determined and made 
available to the investigator and to BI as soon as possible.
In addition, 

obtain a detailed history of current symptoms and concurrent diagnoses and medical 
history according to the ‘DILI checklist’ provided in the ISF 

obtain history of concomitant drug use (including non-prescription medications, 
herbal and dietary supplement preparations), alcohol use, recreational drug use, and 
special diets according to the ‘DILI checklist’ provided in the ISF;

obtain a history of exposure to environmental chemical agents (consider home and 
work place exposure) according to the ‘DILI checklist’ provided in the ISF;
and report these via the CRF.
Clinical chemistry
Alkaline phosphatase, albumin, PT or INR, CK, CK-MB, coeruloplasmin, α-1 antitrypsin, 
transferin, amylase, lipase, fasting glucose, cholesterol, triglycerides
Serology
Hepatitis A (Anti-IgM, Anti-IgG), Hepatitis B (HbsAg, Anti-HBs, DNA), Hepatitis C (Anti-
HCV, RNA if Anti-HCV positive), Hepatitis D (Anti-IgM, Anti-IgG), Hepatitis E (Anti-
HEV, Anti-HEV IgM, RNA if Anti-HEV IgM positive), Anti-Smooth Muscle antibody 
(titer), Anti-nuclear antibody (titer), Anti-LKM (liver-kidney microsomes) antibody, Anti-
mitochondrial antibody
Epstein Barr Virus (VCA IgG, VCA IgM), cytomegalovirus (IgG, IgM), herpes simplex virus 
(IgG, IgM), varicella (IgG, IgM), parvovirus (IgG, IgM), toxoplasmosis (IgG, IgM)

Haematology
Thrombocytes, eosinophils

Provide abdominal ultrasound to rule out biliary tract, pancreatic or intrahepatic 
pathology, e.g. bile duct stones or neoplasm.

Initiate close observation of subjects by repeat testing of ALT, AST, and total 
bilirubin (total and direct) at least weekly until the laboratory ALT and/or AST 
abnormalities stabilize or return to normal, then monitor further as specified in the 
CTP. Depending on further laboratory changes, additional parameters identified e.g. 
by reflex testing will be followed up based on medical judgement and Good Clinical 
Practices (GCP).

After preparation, the solution for infusion may be stored at 2-8°C for up to 24 hours. After 
removal from 2-8°C storage or preparation, the solution must be administered within 60 
minutes if stored at  ≤25°C. Do not freeze.
Chemical and physical in-use stability has been demonstrated for 60 minutes at ≤ 25°C.  In 
addition the time for infusion must not exceed 240 minutes at ≤25°C.
From a microbiological point of view the drug should be used immediately.  If not used 
immediately, the in-use storage times and conditions prior to use are the responsibility of the 
user, and would normally not be longer than 24 hours at 2-8°C (36-46°F), unless preparation 
has taken place in controlled and validated aseptic conditions.

mg/kg multiple dose may further widen 
the safety margin in patients with 
who may require higher doses ≥ 10 mg/kg 
due to protein loss, up-regulation of the 
target, and a potentially higher clearance. 
The prolongation of the infusion time to 
90 minutes has been implemented to 
reduce the theoretical risk of an infusion 
reaction.
2. With amendment number 2 a few 
inconsistencies and typing errors were 
corrected throughout the document.
