Objectives:
-
To investigate the relative bioavailability of 
 BI 655130 
administered as two subcutaneous injections of 
 in the left 
and right periumbilical region compared to a single subcutaneous 
periumbilical injection of 
 BI 655130 
-
To investigate the relative bioavailability of a single subcutaneous 
injection of 
BI 655130 into the thigh compared to a single 
subcutaneous periumbilical injection of 
 BI 655130
-
To investigate safety, tolerability, and pharmacokinetics of 
 BI 
655130 administered as two subcutaneous injections of 
in 
the left and right periumbilical region.
Methodology:
Single dose, open-label in matched-group design
No. of subjects: 
total entered:
48
each treatment:
12
Diagnosis:
Healthy subjects assigned to Dose Group 2 
 left and right 
periumbilical SC injection, 
 of BI 655130), Dose group 3 
 
left and right periumbilical SC injection, 
 of BI 655130) and Dose 
Group 4 
 SC injection in the thigh,

Main criteria
for inclusion:
Healthy male and female subjects, age of 18 to 50 years, body mass index 
(BMI) of 19.0 to 29.9 kg/m2
Test treatment:
BI 655130 
 solution for injection 
dose:
mode of admin.:
Subcutaneous (SC) injection:
-
Two single injections of 
 periumbilical left and right (Dose Group 2)
-
Two single injections of
 periumbilical left and right (Dose Group 3)
-
One single injection of 
 into the thigh (Dose Group 4)
Reference treatment:
BI 655130 
 solution for injection 
dose:
mode of admin.:
One single subcutaneous (SC) injection of 
 periumbilical (Dose Group 1)
Duration of treatment: One day (single dose) for each treatment
Criteria for
pharmacokinetics:
Primary endpoints: AUC0-tz and Cmax
Secondary endpoints: AUC0-
Further parameters of interest as appropriate.
Criteria for safety:
Adverse events (AEs) including clinically relevant findings from the physical 
examination, local tolerability, safety laboratory tests, 12-lead 
electrocardiogram (ECG), vital signs (blood pressure [BP], pulse rate [PR]).
Statistical methods:
Relative bioavailability will be estimated by the ratios of the geometric means 
(test/reference) for the primary and secondary endpoints. Additionally, their 
two-sided 90% confidence intervals (CIs) will be provided. This method 
corresponds to the two one-sided t-tests procedure, each at the 5% 
significance level. Since the main focus is on estimation and not testing, an 
acceptance range was not specified. The statistical model will be an ANOVA 
on the logarithmic scale including effects for ‘treatment’, and ‘matched pair’. 
CIs will be calculated based on the residual error from ANOVA.
Descriptive statistics will be calculated for all endpoints.

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, alcohol breath test, 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 sampling times may be adapted based on information obtained during trial conduct.
5.

findings. 
6.
If several actions are indicated at the same time point, the intake of meals will be the last action.
7.
Confirmation of fitness includes physical examination.
8. 
Only drug screening and alcohol breath test.
9.
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.
10.
EoTrial (End of trial examination) includes physical examination, body weight, vital signs, ECG, safety laboratory, 
recording of AEs and concomitant therapies. EoTrial must not be performed before last PK
 
 sampling.

INTRODUCTION
1.1
MEDICAL BACKGROUND
BI 655130 is a humanized antagonistic monoclonal IgG1 antibody that blocks human IL36 
receptor (IL36R) signalling. Binding of BI 655130 to IL36R is anticipated to prevent the 
subsequent activation of IL36R by cognate ligands (IL36 α, β and γ) and downstream 
activation of pro-inflammatory and pro-fibrotic pathways in inflammatory skin and bowel 
diseases such as generalized pustular psoriasis (GPP), palmoplantar pustulosis (PPP), and 
inflammatory bowel disease (IBD).
Genetic human studies established a strong link between IL36R signalling and skin 
inflammation, as demonstrated by the occurrence of GPP in patients with a loss of function
mutation in IL36Rα,the gene encoding the endogenous inhibitor of IL36R, which resulted in 
uncontrolled IL36R signalling [R14-5158, R15-1421]. Mutations in other genes linked to the 
IL36 pathway such as CARD14 also lead to GPP [R16-0929]. IL36R signalling drives skin 
inflammation in several animal models, further supporting the strong link between IL36R 
biology and skin disorders based on human genetics [R14-5158].
IL36R has been discovered as a target for psoriasis based on (I) the abundant expression of 
all three stimulating ligands in human psoriatic lesional skin [R14-4037], (II) IL36α 
overexpression in murine keratinocytes inducing a psoriatic-like phenotype [R15-1432], (III) 
IL36R KO mice protecting against Imiquimod-induced skin inflammation [R15-1447], and 
(IV) IL36R blockade ameliorating skin inflammation in a transplanted psoriatic skin model 
[R15-1399].
The link between IL36R-driven inflammation and epithelial inflammation has led to the 
hypothesis that IL36R signalling may play an important role in IBD. This hypothesis was 
tested using a series of in vitro and in vivo assays. Immunostaining studies demonstrated that 
both IL36R and its ligands are expressed in intestinal biopsies from patients with Crohn’s 
disease (CD). Human IL36 ligands enhanced intestinal barrier permeability, a hallmark of 
IBD pathogenesis, in primary human intestinal epithelial cells co-cultured with intestinal 
myofibroblasts. The link between IL36R signalling and IBD was further strengthened by 
demonstrating that antagonist anti-mouse IL36R antibodies ameliorated intestinal 
inflammation in both acute and chronic murine colitis models.
The therapeutic rational for an IL36R antagonist in IBD is further based on the correlation of 
a set of IL36-induced genes upregulated in primary human intestinal myofibroblasts, a 
disease relevant cell type, with gene signatures observed in ulcerative colitis (UC) and CD 
patients. Finally, IL36R signalling in disease relevant cells, such as intestinal myofibroblasts 
and macrophages, induces both pro-inflammatory (e.g. IL-1b, IL-8, TNF-α) and tissue 
remodelling related mediators (e.g. TGF-β, MMPs).
Altogether, these findings support a prominent role for IL36R in driving skin and intestinal 
inflammation and support anti-human IL36R antibody BI 655130 as a therapeutic agent for 
epithelial-mediated inflammatory diseases such as GPP, PPP, and IBD.
GPP is characterised by systemic inflammation of the skin and internal organs [R15-1421; 
R16-0933]. Acute GPP is difficult to treat and no approved or standard of care therapy is

available in the US/EU. Current treatment options aiming to control acute GPP and maintain 
response are cyclosporine, acitretin, and methotrexate [R16-0933]. Secukinumab, Infliximab, 
Brodalumab, and Ixekizumab have been approved for GPP exclusively in Japan based on 
small local uncontrolled studies. Treatment is commonly not effective in suppressing acute 
flares during induction and recurrences emerge frequently.
PPP is a form of chronic Pustular Psoriasis characterized by sterile pustules limited to palms 
and soles [R16-0927]. No approved or effective treatment is available.
Both UC and CD are characterised by abdominal pain, fever, bloody diarrhoea, and 
inflammatory lesions in the gastrointestinal mucosa. Current treatment options include 
aminosalicylates, glucocorticoid therapy, azathioprine, 6-mercaptopurine, and biologics 
(blocking TNF or integrin α4β7). Treatment of CD and UC is associated with a significant 
number of patients with primary and secondary non-response. In addition, treatment may be 
limited due to safety and tolerability issues. Therefore, despite progress, there remains a 
significant unmet medical need for new treatment options with an improved safety and 
efficacy profile compared with the current therapeutic standard.
1.2
DRUG PROFILE
1.2.1
Nonclinical pharmacology
BI 655130 is a humanized monoclonal antibody (mAb) of the IgG1 isotype that is directed 
against human IL36R. It is derived from a mouse antibody 81B4 (BI 674308) cloned into a 
human IgG1 Kappa backbone. The mAb uses an IgG1 that has two mutations in the Fc region 
(Leu234Ala and Leu235Ala) to reduce FcγR and complement binding. In addition, to reduce 
charge heterogeneity, the C-terminal lysine residue of the heavy chain is deleted.
For a more detailed description of the BI 655130 profile please refer to the current
Investigator’s Brochure (IB) [c03320877-04].
1.2.2
Safety pharmacology
Specific safety pharmacology studies have not been conducted with BI 655130 as it is not 
pharmacologically active in common toxicology species. Instead, studies were performed 
with BI 674304, the mouse specific anti-IL36R monoclonal antibody and used as a surrogate 
for BI 655130 (please see also Section 1.2.3). There were no clinical signs of toxicity in mice 
after the 13-week administration [c03320877-04].
1.2.3
Toxicology
As BI 655130 does not demonstrate adequate pharmacological activity in common 
toxicology species, a surrogate antibody (BI 674304) specific for mouse IL36R was 
developed and used for toxicology assessments. The toxicology package includes 4, 13 and 
26-week toxicity studies and reproductive/developmental toxicity studies with BI 674304 in 
mice. In addition, the toxicology package includes a 2-week toxicity study in mice with 
BI 655130 and local tolerance, in vitro cytokine release, and tissue cross-reactivity studies.

1.2.4
Nonclinical pharmacokinetics
The pharmacokinetics (PK) of BI 655130 was studied in cynomolgus monkeys. In mice, 
pharmacokinetic studies were performed with the mouse-specific anti-IL36R antibody, 
BI 674304 [c03320877-04].
1.2.5
Clinical experience
In Phase I, BI 655130 has been evaluated in three clinical trials: a first-in-human (FIH) SRD 
trial [c09985235-01], an MRD trial [c09105854-05], and a recently completed relative 
bioavailability study exploring the pharmacokinetics as well as safety and tolerability of a 
newly developed SC formulation (1368-0003, [c10896574-01].
FIH-Study (Trial 1368.1)
The FIH (first-in-human) trial [c09985235-01] explored safety, tolerability, 
pharmacokinetics, and pharmacodynamics of intravenously administered BI 655130 in 
healthy male subjects. Subjects received single ascending IV doses of 
 up to 
 body weight or placebo. Overall, the study included 78 male subjects with 58 
subjects treated with BI 655130 and 20 subjects treated with placebo.
At preferred term level, the most frequently reported treatment-emergent AEs were 
nasopharyngitis (BI 655130: 12/58 subjects [20.7%]; placebo: 3/20 subjects [15.0%]), 
headache (BI 655130: 5/58 subjects [8.6%]; placebo: 3/20 subjects [15.0%]), influenza like 
illness (BI 655130: 4/58 subjects [6.9%]; placebo: 2/20 subjects [10.0%]), and diarrhea 
(BI 655130: 2/58 subjects [3.4%]; placebo: 2/20 subjects [10.0%]).
There were two AEs of moderate intensity, both considered not related to the study drug, 
(injection site hematoma and headache); all remaining AEs were of mild intensity. 
There were no relevant changes compared to placebo for laboratory safety, including clinical 
chemistry, hematology, coagulation parameters, and urinalysis. Deaths, serious AEs, and 
protocol-specified AEs of special interest were not reported in this trial. No clinically relevant 
changes were observed in 12 lead ECGs, vital signs, physical exams, and cardio-monitoring.
MRD study (Trial 1368.2)
Trial 1368.2 [c09105854-05] explored the safety, tolerability, pharmacokinetics, and 
pharmacodynamics of multiple rising intravenous doses of BI. 
In total, 40 subjects entered this trial and were treated. The study consisted of a multiple dose 
part with four dose groups 
 and a single dose arm 
 A total of 32 subjects were assigned to the MRD part. In each of the 4 dose 
groups 6 subjects received BI 655130 and 2 subjects received placebo. Additional 8 subjects 
entered the SD part of the trial with 6 subjects assigned to BI 655130 and 2 subjects assigned 
to placebo [c18789185-01].
Overall, a total of 3 subjects did not complete the planned observation time according to the 
CTP. One subject of the placebo group of the MRD part of the trial withdrew consent after 
having received all 4 planned doses. Two subjects of the 
 MD BI 655130 treatment 
group discontinued treatment because of AEs: 1 subject after having received 1 dose of

BI 655130 and the other subject after having received 3 doses of 
 BI 
655130 (infusion of the third dose was stopped after 8 min). 
The frequency of subjects with at least 1 drug-related treatment-emergent AE was similar for 
the MD placebo group and the MD BI 655130 treatment groups (ranging from 16.7% to 
66.7%), and no dose-dependency was observed. The drug related AE with the highest 
incidence was headache, which was reported in 5 of 6 subjects in the 
 group. 
Additionally, gastrointestinal disorders (abdominal discomfort, diarrhoea, and nausea) 
appeared to occur more often in subjects who received BI 655130 than in subjects who 
received placebo. Infusion related reaction, decreased appetite, and anxiety were only 
observed in the 
 MD BI 655130 treatment group. In total, 2 out of the 24 subjects 
(8.3%) who received multiple doses of BI 655130 were reported with AEs leading to
discontinuation of trial drug, 1 subject with mild pyrexia after the first infusion and 1 subject 
with mild and transient infusion related reactions during the third infusion. One subject of the 
placebo group of the MRD part of the trial withdrew consent after having received all 4 
planned doses.
Deaths, serious AEs, and protocol-specified AEs of special interest were not reported in this 
trial. No relevant changes were observed in safety laboratory tests, vital signs, and ECGs. For 
further details, please refer to the final study report [c18789185-01].
Trial 1368-0003
This study explored the pharmacokinetics as well as safety and tolerability of an SC
formulation of BI 655130 at 2 different dose strengths of 
 and 
 
in an open-label, sequential group design. Furthermore, the relative bioavailability of the 
 SC dose was compared with one single 
 IV dose of BI 655130 in an open-
label, matched group design.
The study included a total of 36 healthy male and female subjects with 12 subjects per 
treatment group. 
Based on preliminary data the SC formulation is considered to be well tolerated, the 
standardised assessment of injection pain, redness, induration, swelling, heat, or other 
findings did not reveal any noteworthy changes. There were three subjects with a transient 
occurrence of redness and one subject with a swelling at injection site 30 minutes after the SC 
injection. No further local tolerability findings were reported, in particular no injection pain 
and no induration at injection site during an observation period of up to 6 months.
Regarding systemic AEs, there were no AEs of severe intensity. Deaths, serious AEs, and 
protocol-specified AEs of special interest were not reported in this trial. No relevant changes 
were observed in safety laboratory tests, vital signs, and ECGs. The clinical part of the study 
has been completed. The study report is under preparation (final safety tables available, 
[c18789185-01]).
Pharmacokinetics
The PK parameters of BI 655130 after a single IV infusion from Trial 1368.1 are shown in 
Table 1.2.5:1. BI 655130 plasma levels were first detected at a dose level of

AUC0-inf results should be considered for informational purposes only given the high %_AUC 
of extrapolated values (>50%) for the 
 dose groups. Exposure in terms of 
AUC0-tz and Cmax of BI 655130 increased with increasing dose in a greater than dose-
proportional manner from 
 and in a dose-proportional manner from 
 In the higher dose groups with apparent linear PK characteristics 
 
 the half-life (t1/2) of BI 655130 was in the range of 20.4 to 33.9 days. However, 
because of the relatively short sampling time, these values should be considered an estimate 
only.
Overall, PK data suggest target-mediated drug disposition (TMDD) kinetics for BI 655130.

Pharmacodynamics
Pharmacodynamic effects in Trials 1368.1 (SRD) and 1368.2 (MRD) were assessed by 
indirect target engagement (ITE) of IL36R by BI 55130 using an ex-vivo whole blood 
stimulation assay. Whole blood was taken before and after treatment of subjects with BI 
655130 or placebo and stimulated with IL36γ ligand. After preparation of plasma, the 
resulting production of macrophage inflammatory protein (MIP)-1β was quantified via an 
immunoassay as an exploratory biomarker. MIP-1β levels are expected to inversely correlate 
with the level of IL36R engagement by BI 655130.
In the single rising dose trial (1368.1), doses of 
 and above showed percent inhibition 
of MIP-1β of at least 94% as compared to baseline during the entire time course up to 1680 h. 
Furthermore, in the interim analysis of ITE in the multiple rising dose trial (1368.2) for dose 
groups evaluated so far, the inhibition of MIP-1β was at least 91% as compared to baseline 
during the entire time course up to 672 h for 
 dose groups as compared 
to placebo. This demonstrates that BI 655130 is on-target for the time points analyzed.
Residual Effect Period
The Residual Effect Period (REP) of BI 655130 is up to 16 weeks. This is the period after the 
last dose with measurable drug levels and/or pharmacodynamic effects still likely to be 
present.
For a more detailed description of the BI 655130 profile please refer to the current
Investigator’s Brochure (IB) [c03320877-04].

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
BI 655130 is in development for the treatment of GPP, PPP, CD, and UC. BI 655130 is 
currently in Phase II development.
In Phase I studies BI 655130 was mainly administered as intravenous infusion. However, the 
subcutaneous injection route is considered to be required to enable in upcoming therapeutic 
studies the self-administration of BI 655130 by patients. For this reason a subcutaneous 
injection formulation is undergoing clinical development.
Recently, the clinical part of a Phase 1 study (Study 1368-0003) has been completed 
exploring the characteristics of a subcutaneous formulation of BI 655130 with particular 
focus on relative bioavailability compared to an intravenous formulation. A further objective 
was the assessment of local tolerability. In this study, the relative bioavailability of a single 
SC injection containing 
of BI 655130 
was in a range of about 50% while 
relative bioavailability increased to 70% for a single SC injection of 
 of BI 655130 
 
 
To further elucidate the origin of the observed potentially dose dependent increasing 
bioavailability, the current study will compare the pharmacokinetics (PK) of a single SC 
injection of 
 of BI 655130 with the PK of two SC injections of 
 
of BI 655130 
This design will investigate the impact of local factors at the SC 
injection site on the overall exposure of BI 655130 which may contribute to the lower 
bioavailability observed in the preceding clinical study.
The current study will also investigate the impact on relative bioavailability regarding the site 
of injection (abdomen and thigh) to enable the switch of injection site if needed.
To widen the SC dose range the current study will also investigate a subcutaneous dose of 
 of BI 655130 corresponding to two single periumbilical SC injections of 
 (i.e. 
total injection volume 
 
2.2
TRIAL OBJECTIVES
The primary objective of this trial is to investigate the relative bioavailability of 
 
BI 655130 administered as two subcutaneous injections of
 in the left and right 
periumbilical region compared to a single subcutaneous periumbilical injection of 
 
BI 655130 
The secondary objective is to investigate the relative bioavailability of a single subcutaneous 
injection of 
 BI 655130 into the thigh compared to a single subcutaneous 
periumbilical injection of 
 BI 655130. 
A further objective is to investigate safety, tolerability, and pharmacokinetics of 
 BI 
655130 administered as two subcutaneous injections of 
 in the left and right 
periumbilical region.

information as how to collect the data for that information, is provided in Section 5.
2.3
BENEFIT - RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to optimize treatment regimen of 
the subcutaneous formulation for potential use as maintenance therapy in patients. The 
subjects are exposed to the risks of the study procedures and the risks related to the exposure 
to the trial medication.
Procedure-related risks
The use of an indwelling venous catheter for the purpose of blood sampling may be 
accompanied by mild bruising and also, in rare cases, by transient inflammation of the wall of 
the vein. In addition, in rare cases a nerve might be injured while inserting the venous 
catheter, potentially resulting in paresthesia, reduced sensibility, and/or pain for an indefinite 
period. The same risks apply to veinipuncture for blood sampling.
The total volume of blood withdrawn during the entire study per subject will not exceed the 
volume of a normal blood donation 
 No health-related risk to healthy subjects is 
expected from this blood withdrawal.
Drug-related risks and safety measures
The toxicology package conducted in mice with a mouse-specific antibody (BI 674304)
includes 4, 13 and 26-week toxicity studies and reproductive/developmental toxicity studies 
without any findings which would preclude clinical studies in humans (see IB 
[c03320877-04]).
The clinical safety and tolerability profile of BI 655130 was comparable to placebo in male 
subjects following once weekly intravenous doses of up to
 body weight
administered over 4 weeks. There were no deaths or other serious adverse events. There were 
no dose or exposure related abnormalities in safety laboratory parameters and no safety or 
tolerability concerns that would preclude further clinical development of BI 655130.
Recently the clinical part of an initial with a subcutaneous formulation has been completed. 
The maximum tested SC dose was
 of BI 655130 (
 injection volume). The 
study did not reveal systemic or local AEs which would preclude further clinical studies with 
the SC formulation. The observed exposure at 
 following SC injection was about 6
fold lower compared to the maximum exposure in completed clinical studies with an IV 
infusion of up to 
 of BI 655130. Therefore even the planned maximum SC dose of 
 of BI 655130 is not expected to exceed exposure limits already tested in humans.
Based on studies in healthy subjects, no specific drug-related risks are anticipated. 
Nevertheless, the following safety measures are/will be applied in this study in order to 
minimize the risk for the healthy subjects:


The study will start with Dose Group 1 and 2 (periumbilical SC dose of 
 of 
BI 655130). Provided no dose limiting AEs occurred as approved 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 up to Day 10
(see Section 3.1), the study will pursue with Dose Group 3 (periumbilical SC dose of
 of BI 655130) and Dose Group 4 (SC dose of 
 of BI 655130 in the 
thigh). Dose Group 3 will be divided into 2 cohorts. In the first week, 6 subjects will 
be treated. There will be an interval of at least 1 week after start of dosing in the first 
cohort before start of dosing of the second cohort of Dose Group 3.

At any time during the ongoing study, further dosing will be stopped in case of safety 
and tolerability concerns based on the criteria defined in Section 3.1.

Monitoring of ECG, vital signs, and extensive safety laboratory testing (Table 5.2.3:1)
is conducted throughout the study.

After dosing, the subjects will stay at the site for at least 48 hours.

BI 655130 will be administered in a hospital setting and subjects will be under close 
medical observation during their hospitalisation (see Section 6.2), as well as after their 
discharge and until the end of observation period. Safety will be closely monitored 
during site visits for both expected and unexpected adverse events.
Currently there are no data available to suggest interactions of BI 655130 [c03320877-04].
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this study requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety, see also Section 5.2.2.1, adverse events of special interest.
Based on the preclinical and clinical information for BI 655130, healthy subjects are not 
expected to be exposed to undue risks and adverse events in relation to the information 
expected from this trial. Considering the medical need for the development of an effective 
and well tolerated drug for the therapy of IBD and GPP, the benefit of this trial is considered 
to outweigh the potential risks and justifies the exposure of healthy subjects.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This study will explore the relative bioavailability, safety, and tolerability following a
subcutaneous (SC) injection of BI 655130 at different dose strengths, injection volumes, and 
injection sites: 
-
One SC injection of 
 periumbilical (Dose Group 1)
-
Two SC injections of 
each periumbilical left and right (Dose Group 2)
-
Two SC injections of 
each periumbilical left and right (Dose Group 3) 
-
One SC injection of 
 in the thigh (Dose Group 4)
The total dose in Dose Group 1, 2, and 4 is 
 of BI 655130 and the total dose in Dose 
Group 3 is 
 of BI 655130.
The study will be conducted in a single-dose, open-label, matched-group design. The 
exposure in Dose Group 1 will be used as reference to assess the relative bioavailability of 
Dose groups 2 - 4. For details refer to Section 4.1.
The study will start with Dose Group 1 and 2. After completion of treatment of the first two 
dose groups, the study will continue with Dose Group 3 and 4. At any time during the 
ongoing study, further dosing will be stopped in case of safety and tolerability concerns based 
on the pre-specified trial-specific stopping criteria (Section 3.3.4.2).
The Dose Group 3 will follow a staggered administration with treatment of 6 subjects (cohort 
A) in the first week and the remaining subjects (cohort B) from Week 2. 
A documented Safety Review of Dose Group 1 and 2 at least 10 days after last dosing in 
Dose Group 2 must take place prior to continue the study with Dose Groups 3 and 4. 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. Continuation of the study 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 8 evaluable subjects in
each of the Dose Group 1 and 2 are required to decide about continuation with the remaining 
dose groups.
The minimum data set for review consists of the following data:

AEs (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)

Vital signs 

Clinical laboratory tests 

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 or a delegate is 
responsible for organisation 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.

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
The study will be conducted according to a single-dose, open-label design with matched
groups.
The resulting group sizes (see Section 7.6) are considered to be sufficient for the exploratory
evaluation of pharmacokinetics. The assignment of matched healthy volunteers is a useful
method to control for other factors which may influence the pharmacokinetics of BI 1467335
in a renal impaired population.
The open-label treatment is not expected to bias results, since the primary endpoints are
derived from measurement of plasma concentrations of the analytes provided by a
bioanalytical laboratory. It is also considered sufficiently accurate as the trial observations are
objective (PK, laboratory) and over-reporting of AEs is unlikely.
No placebo group is included because the study is open-label with a focus on PK. Local 
tolerability is an additional objective and will remain relevant in case of dose limiting local 
AEs, whether placebo controlled or not. The systemic tolerability of BI 655130 has already
been evaluated up to 
 MRD, resulting in a far higher exposure compared to the 
expected exposure of the current study.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 48 healthy male and female subjects (12 in each dose group) will enter the 
study. They will be recruited from the volunteers' pool of the trial site. Healthy subjects 
assigned to Dose Groups 2 - 4 will be matched on an individual level for gender and body 
weight (± 10%) to subjects assigned to Dose Group 1 
 periumbilical injection).
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
Subjects will only be included into the trial, if they meet the following criteria:
1. Healthy male or female subjects according to the investigator’s assessment, based on a 
complete medical history including a physical examination, vital signs (BP, PR), 12-lead 
ECG, and clinical laboratory tests

>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 
marked peak aminotransferase (ALT and/or AST) elevations ≥10-fold ULN and/or needs 
to be followed up according to 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.
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 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 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 (i.e., 16 weeks, see Section 1.2.5), 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.
If it is known that a subject becomes pregnant during the trial, the subject has to be removed 
from the trial. The subject is to be followed until she has given birth or until the end of 
pregnancy. The subject’s data are to be collected until the end of the trial (last visit of last 
subject) and reported in the CTR. For reporting of pregnancy and all related events refer to 
Section 5.2.2.2.
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 are not met
3. Violation of GCP, or the CTP, or the contract with BI by the 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. Further dosing will be stopped if at least 2 subjects in one dose group show 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. Replacement of subjects should always be done in mutual agreement with the 
principal investigator. A replacement subject will be assigned a unique study subject number, 
and will be assigned to the same treatment and matching criteria as the subject he or she 
replaces.

At the time of use, the SC solutions for dosing will be prepared as detailed in the instruction 
given in the ISF.
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 
Dose Group 1, matching subjects will be allocated to the other dose groups. Therefore, the 
allocation of subjects to dose groups is not influenced by trial personnel, but only by the 
subjects’ temporal availability. As the study includes healthy subjects from a homogenous 
population matched for gender and body weight, relevant imbalances between the dose 
groups are not expected.
The allocation of subjects will be performed prior to the administration of trial medication. 
Once a subject number has been assigned to a treatment group, it cannot be reassigned to any 
other treatment group.
4.1.3
Selection of doses in the trial
The dose of 
 of BI 655130 selected for this trial has been selected to correspond to the 
potential dose for maintenance treatment in clinical trials in patients. The highest dose tested 
in this trial 
 of BI 655130) will be included to widen the SC dose range.

Following an overnight fast of at least 10 hours, the medication will be administered. Trial 
drug will be injected subcutaneously in the abdominal region or into the thigh. Detailed 
handling instructions will be provided in the ISF. Subjects will be kept under close medical
surveillance until 48 hours following drug administration. For restrictions with regard to diet,
see Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
No blinding will be performed. This Phase I trial will be handled in an open fashion 
throughout (that is, during the conduct, including data cleaning and preparation of the 
analysis). This is considered acceptable because the potential for bias seems to be low and 
does not outweigh practical considerations. Emergency envelopes will not be provided, since 
the treatments of all subjects are known in this open-label trial.

the inventory at the site, the use by each subject, and the 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 will maintain records that document adequately that the subjects 
were provided the doses specified by the CTP, and that reconcile all investigational products

OTHER TREATMENTS, EMERGENCY  PROCEDURES,
RESTRICTIONS
4.2.1
Other treatments and emergency procedures
There are no special emergency procedures 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
In principle, no concomitant therapy is allowed except for hormonal contraceptives or ovary 
hormone replacement. All concomitant or rescue therapies will be recorded (including time 
of intake on study days) on the appropriate pages of the CRF.
4.2.2.2
Restrictions on diet and life style
While admitted to the trial site the subjects are restricted from consuming any other foods or 
drinks than those provided by the staff. Standardised meals will be served at the time points 
described in the Flow Chart. On Day 1, no food is allowed for at least 10 h before and 2 h 
after administration of the study drug.
From 1 h before until 2 h after SC injection, fluid intake is not allowed.
Smoking is not allowed during in-house confinement at the trial site.
Alcoholic beverages are not permitted starting 7 days before the administration of trial 
medication until Day 15. From Day 15 onwards, alcohol consumption is restricted to 20 g 
alcohol per day corresponding to 0.5 L beer or 0.2 L of white wine per day.
Methylxanthine-containing drinks or foods (such as coffee, tea, cola, energy drinks, and 
chocolate) are not allowed during the in-house confinement.
Poppy-seed containing products are not allowed starting 2 days before screening and 2 days 
before admission to trial site (Day -1) to avoid false positive drug screening results.

VARIABLES AND THEIR ASSESSMENT
5.1
EFFICACY - CLINICAL PHARMACOLOGY
5.1.1
Endpoints of efficacy
No efficacy endpoints will be evaluated in this trial.
5.1.2
Assessment of efficacy
Not applicable.
5.2
SAFETY
5.2.1
Endpoints of safety
Safety and tolerability of the investigational drug will be assessed based on: 

Adverse events (including clinically relevant findings from the physical examination)

Safety laboratory tests

Vital signs (blood pressure, pulse rate)

Local tolerability
These parameters will be evaluated in a descriptive way only, and are therefore considered to 
be ‘further parameters of interest’. A confirmatory analysis is not planned (see Section 7.3). 
5.2.2
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.
The following should also be recorded as an AE in the CRF and BI SAE form (if applicable):

Worsening of the underlying disease or of other pre-existing conditions

Chances 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 to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.

Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:

results in death, 

is life-threatening, which 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  

requires prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, 

is a congenital anomaly/birth defect, 

is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions. 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.
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the drug and must be reported as 
described in Section 5.2.2.2, subsections ‘AEs collection’ and ‘AE reporting to sponsor and 
timelines’.
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 
defined above.
The latest list of ‘Always Serious AEs’ can be found in the eDC system, an electronic data 
capture system which allows the entry of trial data at the trial site. These events should 
always be reported as SAEs as described above.
Adverse events of special interest
The term adverse event of special interest (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. AESIs need to be reported to the sponsor’s 
Pharmacovigilance Department within the same timeframe that applies to SAEs, please see 
Section 5.2.2.2.
The AESI in this trial is hepatic injury, as defined by the following alterations of hepatic 
laboratory parameters:


an elevation of AST (aspartate transaminase) and/or ALT (alanine aminotransferase) 
≥3-fold ULN combined with an elevation of total bilirubin ≥2-fold ULN measured in 
the same blood sample, or 

aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN.
These lab findings constitute a hepatic injury alert and the subjects 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 that 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 (severity) of AEs
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
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 reduced).
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 trial drug treatment continues or remains 
unchanged. 
5.2.2.2
Adverse event collection and reporting
AE 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 carefully 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, intensity of the event, and
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 until an 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 any occurrence of cancer and related SAEs and related 
AESIs of which the investigator may become aware of by any means of 
communication, e.g. phone call. Those AEs should, however, not be reported 
in the CRF.

AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs that 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 the initial 
information.
Information required
All (S)AEs, including those persisting after the individual subject’s end of trial, must be 
followed up until they have resolved, have been assessed as ‘chronic’ or ‘stable’, or no 
further information can be obtained.
Pregnancy
In rare cases, pregnancy might occur in a clinical trial. Once a subject has been enrolled in 
the clinical trial and has taken trial medication, the investigator must report any drug 
exposure during pregnancy in a trial participant immediately (within 24 hours) by means of 
Part A of the Pregnancy Monitoring Form to the sponsor’s unique entry point.
Similarly, potential drug exposure during pregnancy must be reported if a partner of a male 
trial participant becomes pregnant. This requires a written consent of the pregnant partner.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B)
as well as non-trial specific information and consent for the pregnant partner.
Pregnancy itself is not to be reported as an AE. In the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form 
is to be completed. If there is an SAE and/or AESI associated with the pregnancy, an SAE 
form must be completed in addition.
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 parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF, Section 10.

The laboratory tests listed in Table 5.2.3: 1 and 5.2.3: 2 will be performed 
 
 with the exception of the drug screening and pregnancy 
tests. These tests will be performed at the trial site using 'Alere Triage TOX Drug Screen' and 
Alere® –HCG urine, respectively.
Laboratory data will be transmitted electronically from the laboratory to the trial site.
5.2.4
Electrocardiogram
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a
computerised electrocardiograph (e.g. MAC 5500, GE Healthcare) at the time points given in 
the Flow Chart.
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 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.
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) and the repeated ECG will be used for analysis. Additional (unscheduled) ECGs 
may be collected by the investigator for safety reasons.
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. 
5.2.5
Assessment of other safety parameters
5.2.5.1
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) will be measured by a blood pressure monitor (e.g. 
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 be made 
using the same type of blood pressure recording instrument on the same arm if possible.
5.2.5.2
Medical examinations
At screening, the medical examination will include demographics including height and body 
weight, smoking and alcohol history, relevant medical history and concomitant therapy, 
review of inclusion and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, 
laboratory tests (including drug screen and pregnancy test), and a physical examination. The 
end of trial examination will include review of vital signs, 12-lead ECG, laboratory tests, 
recording of AEs and concomitant therapy and a physical examination with determination of 
weight.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine 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 SC 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.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Date and clock time of drug administration and pharmacokinetic sampling will be recorded in 
the CRFs.
Exact time points of plasma sampling will be derived from the electronic data capturing 
system LabPas and documented in the CRFs by the medical personnel or sent as electronic 
files to the trial data manager. The actual sampling times will be used for determination of 
pharmacokinetic parameters.
5.5.1
Pharmacokinetic endpoints

Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 655130 plasma concentrations, approximately 
 of blood will 
be taken from an antecubital or forearm vein into a K2-EDTA (dipotassium 
ethylenediaminetetraacetic acid) anticoagulant blood drawing tube at the times indicated in 
the Flow Chart under “Plasma PK”. Blood will be withdrawn by means of either an 
indwelling venous catheter or by venipuncture with a metal needle.
The K2-EDTA-anticoagulated blood samples will be mixed gently and placed on ice until 
centrifugation for about 10 min at about 2000 g to 4000 g and at approximately 4°C. The 
blood should be centrifuged to produce plasma as soon as possible after collection, but not 
later than 30 min after withdrawal. 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 
 of plasma each. The plasma samples 
will be stored in a freezer at about -70°C or below at the clinical site until shipment to the 
analytical laboratory.

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening and end of trial examination are given in the 
Flow Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1 are to be performed and completed within a 3 h-period prior to the 
trial drug administration. 
The acceptable deviation from the scheduled time for vital signs, ECG and safety laboratory
will be

± 15 min up to including 12 h

± 30 min from 12h up to including 48 h

± 120 min from 48 h up to Day 8

± 48h from Day 9 up to Day 15

± 72h from >Day 15 up to the last assessments
If scheduled in the Flow Chart at the same time as a meal, meal will be only provided after 
completion of the concomitant procedures. Furthermore, if several measurements including 
venipuncture are scheduled for the same time, vital signs and 12-lead ECG recordings have to 
be done first and 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 Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period

then be allowed to leave the trial site after formal assessment and confirmation of their 
fitness. On all other study days, the study will be performed in an ambulatory fashion.
Details on treatments and procedures of administration are described in Section 4.1.4.
For details on time points and procedures for collection of plasma samples for PK analysis, 
refer to Flow Chart and Section 5.5.2. 
The safety measurements performed during the treatment period are specified in Section 5.2
of this protocol and in the Flow Chart. For details on time points for all other trial procedures, 
refer to the Flow Chart. AEs and concomitant therapy will be assessed continuously from 
screening until the end of trial examination.
6.2.3
End of trial period
For AE assessment, laboratory tests, 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 prematurely the study before the end of the planned treatment 
period (i.e., Day 176 ±3) 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. (S)AEs persisting after subject’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.
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 trial objectives are stated in Section 2.2.
For the purpose of defining reference and test treatments, the following terminology will be 
used. The reference treatment (R) will refer to dose group 1, test treatment 1 (T1) refers to 
dose group 2, test treatment 2 (T2) refers to dose group 4 and test treatment 3 (T3) refers to 
dose group 3. 
7.1.2
Endpoints
Relative bioavailability is to be determined on the basis of the primary and secondary 
pharmacokinetic endpoints (see Section 5.5.1).
Safety and tolerability will be determined on the basis of the parameters specified in 
Section 5.2.1.
7.1.3
Model
The statistical model used for the analysis of primary and secondary endpoints will be an 
ANOVA (analysis of variance) model on the logarithmic scale. This model will include 
effects accounting for the following sources of variation: ‘treatment’ and ‘matched pair’. For 
each matched pair in the study a pair number will be assigned for analysis purpose. The 
resulting variable ‘matched pair’ will be considered as random effect.
The model is described by the following equation:
ykjm = + k + pj + eijkm, where
ykjm = logarithm of response (endpoint) measured on subject m in pair j receiving 
treatment k
= the overall mean,
k = the kth treatment effect, k=1,..,4,
pj = the jth matched pair effect,
eijkm = the random error associated with the mth subject in sequence i who received
treatment k in period j.

 ) i.i.d. and pj, eijk are independent random variables (note 
that the indices ‘B’ and ‘W’ correspond to ‘between’ pairs and ’within’ pairs variability, 
respectively).
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of the different dose groups will be estimated by the ratios of the 
geometric means (test/reference) for the primary and secondary PK endpoints. Additionally, 
their two-sided 90% confidence intervals (CIs) will be provided. This method corresponds to 
the two one-sided t-tests procedure, each at the 5% significance level. Since the main focus is 
on estimation and not testing, an acceptance range was not specified, that is, no hypothesis 
will be tested.
7.3
PLANNED ANALYSES
7.3.1
Primary analyses
The pharmacokinetic endpoints listed in 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].
Plasma concentration data and parameters of a subject will be included in the statistical
pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a protocol
violation relevant to the evaluation of PK (to be decided no later than in the Report Planning
Meeting) or due to PK non-evaluability (as revealed during data analysis, based on the 
criteria specified below). Exclusion of a subject’s data will be documented in the clinical trial
report.
Relevant protocol violations may be:

Incorrect trial medication taken, that is, the subject received at least one dose of trial
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medications
Plasma concentrations and/or parameters of a subject will be considered as non-evaluable, if
for example:

The subject experiences emesis that occurred at or before 2 times median tmax of the 
respective treatment (median tmax is to be determined excluding the subjects 
experiencing emesis)

A predose concentration is >5% Cmax value of that subject

Missing samples/concentration data at important phases of PK disposition curve

001-MCS-40-106-RD-13 (5.0) / Saved on: 15 Jul 2014
The following analysis sets will be defined for this trial:

Treated set (TS):
This subject set includes all subjects from the RS who were documented to have 
received one dose of study drug. This is the full analysis set population in the sense of 
ICH-E9

Pharmacokinetic parameter set (PKS):
This subject set includes all subjects in the TS who provide at least one primary or 
secondary PK parameter that was not excluded according to the description above. 
Thus, a subject will be included in the PKS even if he/she contributes only one PK 
parameter value for one period to the statistical assessment
Point estimates of the ratios of the geometric means (test/reference) for the primary and 
secondary endpoints (see Sections 5.5.1.1 and 5.5.1.2), and their two-sided 90% confidence 
intervals (CIs) will be provided.
To this end, the PK endpoints will be log transformed (natural logarithm) prior to fitting the 
ANOVA model (cf. Section 7.1.3). For each endpoint, the difference between the expected 
means for log(T)-log(R) will be estimated by the difference in the corresponding adjusted 
means (Least Squares Means), and a two-sided 90% confidence interval based on the 
t-distribution will be computed. These quantities will then be back-transformed to the original 
scale to provide the point estimate and 90% CIs for each endpoint.
The comparisons of interest will be T1 vs. R, T2 vs. R, and T3 vs. R. Further comparisons
may be investigated if appropriate (e.g. T1 vs. T2) and will be described in the TSAP.
7.3.2
Secondary analyses
The same statistical model as stated in Section 7.1.3 will be repeated for the primary and 
secondary endpoints but with all sources of variation considered as fixed effects.
Additionally, the pharmacokinetic parameters listed in Section 5.5.1.3 will be calculated and 
analysed descriptively, if feasible.
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
analysis. Safety analyses will be descriptive in nature and will be based on BI standards. No 
hypothesis testing is planned.
The analyses will be done by ‘treatment at onset’.
Treatments will be compared 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.

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 end of the residual 
effect period (see Section 1.2.5) will be assigned to the treatment period. Events after the 
residual effect period but prior to next intake or end of trial examination will be summarized 
as ‘follow-up’. The follow-up will be summarised according to previous treatment. These 
assignments including the corresponding time intervals will be defined in detail in the TSAP. 
AEs occurring after the last per-protocol contact but entered before database lock will be 
reported to drug safety only and will not be captured in the trial database.
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, severity and causal relationship of AEs will be tabulated by 
treatment, 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 as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data observed at screening, baseline, during the course of 
the trial and at the end-of-trial evaluation will be assessed with regard to possible changes 
compared to findings before start of treatment.
Relevant ECG findings will be reported as AEs.
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 relevant SOP of the Sponsor [001-MCS-36-472].
Individual plasma concentration data and the pharmacokinetic parameters will be tabulated,
graphically displayed and summarized by descriptive statistics. The analysis of PK endpoints 
will be based on PKS.
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.
7.4
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 drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant Corporate 
Procedure 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
The study will not be randomised as individually matched subjects will be used. Thus, this 
section is not applicable.
7.6
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 4*12 = 48 subjects in the trial, because this sample size is 
considered sufficient to achieve the aims of this exploratory trial. With this sample size, the 
following precision in estimating the ratio of geometric means (test/reference) can be 
expected with 95% probability. Precision is defined as the ratio of upper CI limit to the 
relative BA estimate. Note that the precision is independent of the actual ratio of geometric 
means.

The observed inter-individual geometric coefficient of variation (gCV) in a previous trial 
(1368.3) was roughly 30% for Cmax and for AUC. For various assumptions on the gCV, 
Table 7.6: 1 provides an overview of the precision for estimating the ratio of geometric

*Ratio of geometric means (test/reference) for a PK endpoint is defined by exp(T)/exp(R).
The 90% confidence interval limits in the table were derived by
CI limit, = exp(ln(θ) ± ω),
with θ being the ratio (T/R) on original scale and ω the distance from the estimate θ to either 
confidence interval limit on the log-scale, which was obtained from the achievable precision

Main criteria
for inclusion:
Healthy male and female subjects, age of 18 to 50 years, body mass index 
(BMI) of 19.0 to 29.9 kg/m2
Test treatment:
BI 655130 
 solution for injection 
dose:
mode of admin.:
Subcutaneous (SC) injection:
-
Two single injections of 
 periumbilical left and right (Dose Group 2)
-
Two single injections of
 periumbilical left and right (Dose Group 3)
-
One single injection of 
 into the thigh (Dose Group 4)
Reference treatment:
BI 655130 
 solution for injection 
dose:
mode of admin.:
One single subcutaneous (SC) injection of 
 periumbilical (Dose Group 1)
Duration of treatment: One day (single dose) for each treatment
Criteria for
pharmacokinetics:
Primary endpoints: AUC0-tz and Cmax
Secondary endpoints: AUC0-
Further parameters of interest as appropriate.
Criteria for safety:
Adverse events (AEs) including clinically relevant findings from the physical 
examination, local tolerability, safety laboratory tests, 12-lead 
electrocardiogram (ECG), vital signs (blood pressure [BP], pulse rate [PR]).
Statistical methods:
Relative bioavailability will be estimated by the ratios of the geometric means 
(test/reference) for the primary and secondary endpoints. Additionally, their 
two-sided 90% confidence intervals (CIs) will be provided. This method 
corresponds to the two one-sided t-tests procedure, each at the 5% 
significance level. Since the main focus is on estimation and not testing, an 
acceptance range was not specified. The statistical model will be an ANOVA 
on the logarithmic scale including effects for ‘treatment’, and ‘matched pair’. 
CIs will be calculated based on the residual error from ANOVA.
Descriptive statistics will be calculated for all endpoints.

vital signs, ECG, safety laboratory (under fasting conditions), drug screening, alcohol breath test, 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 sampling times may be adapted based on information obtained during trial conduct.
5.
Standardized assessment of local tolerability using the criteria swelling, induration, heat, redness, pain or other 
findings. 
6.
If several actions are indicated at the same time point, the intake of meals will be the last action.
7.
Confirmation of fitness includes physical examination.
8. 
Only drug screening and alcohol breath test.
9.
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.
10.
EoTrial (End of trial examination) includes physical examination, body weight, vital signs, ECG, safety laboratory, 
recording of AEs and concomitant therapies. EoTrial must not be performed before last PK and ADA sampling. 
11.
Safety laboratory is to be taken within five days prior to study drug administration and can be omitted if the
screening examination is performed between Day -5 and Day -3.

INTRODUCTION
1.1
MEDICAL BACKGROUND
BI 655130 is a humanized antagonistic monoclonal IgG1 antibody that blocks human IL36 
receptor (IL36R) signalling. Binding of BI 655130 to IL36R is anticipated to prevent the 
subsequent activation of IL36R by cognate ligands (IL36 α, β and γ) and downstream 
activation of pro-inflammatory and pro-fibrotic pathways in inflammatory skin and bowel 
diseases such as generalized pustular psoriasis (GPP), palmoplantar pustulosis (PPP), and 
inflammatory bowel disease (IBD).
Genetic human studies established a strong link between IL36R signalling and skin 
inflammation, as demonstrated by the occurrence of GPP in patients with a loss of function
mutation in IL36Rα,the gene encoding the endogenous inhibitor of IL36R, which resulted in 
uncontrolled IL36R signalling [R14-5158, R15-1421]. Mutations in other genes linked to the 
IL36 pathway such as CARD14 also lead to GPP [R16-0929]. IL36R signalling drives skin 
inflammation in several animal models, further supporting the strong link between IL36R 
biology and skin disorders based on human genetics [R14-5158].
IL36R has been discovered as a target for psoriasis based on (I) the abundant expression of 
all three stimulating ligands in human psoriatic lesional skin [R14-4037], (II) IL36α 
overexpression in murine keratinocytes inducing a psoriatic-like phenotype [R15-1432], (III) 
IL36R KO mice protecting against Imiquimod-induced skin inflammation [R15-1447], and 
(IV) IL36R blockade ameliorating skin inflammation in a transplanted psoriatic skin model 
[R15-1399].
The link between IL36R-driven inflammation and epithelial inflammation has led to the 
hypothesis that IL36R signalling may play an important role in IBD. This hypothesis was 
tested using a series of in vitro and in vivo assays. Immunostaining studies demonstrated that 
both IL36R and its ligands are expressed in intestinal biopsies from patients with Crohn’s 
disease (CD). Human IL36 ligands enhanced intestinal barrier permeability, a hallmark of 
IBD pathogenesis, in primary human intestinal epithelial cells co-cultured with intestinal 
myofibroblasts. The link between IL36R signalling and IBD was further strengthened by 
demonstrating that antagonist anti-mouse IL36R antibodies ameliorated intestinal 
inflammation in both acute and chronic murine colitis models.
The therapeutic rational for an IL36R antagonist in IBD is further based on the correlation of 
a set of IL36-induced genes upregulated in primary human intestinal myofibroblasts, a 
disease relevant cell type, with gene signatures observed in ulcerative colitis (UC) and CD 
patients. Finally, IL36R signalling in disease relevant cells, such as intestinal myofibroblasts 
and macrophages, induces both pro-inflammatory (e.g. IL-1b, IL-8, TNF-α) and tissue 
remodelling related mediators (e.g. TGF-β, MMPs).
Altogether, these findings support a prominent role for IL36R in driving skin and intestinal 
inflammation and support anti-human IL36R antibody BI 655130 as a therapeutic agent for 
epithelial-mediated inflammatory diseases such as GPP, PPP, and IBD.
GPP is characterised by systemic inflammation of the skin and internal organs [R15-1421; 
R16-0933]. Acute GPP is difficult to treat and no approved or standard of care therapy is

available in the US/EU. Current treatment options aiming to control acute GPP and maintain 
response are cyclosporine, acitretin, and methotrexate [R16-0933]. Secukinumab, Infliximab, 
Brodalumab, and Ixekizumab have been approved for GPP exclusively in Japan based on 
small local uncontrolled studies. Treatment is commonly not effective in suppressing acute 
flares during induction and recurrences emerge frequently.
PPP is a form of chronic Pustular Psoriasis characterized by sterile pustules limited to palms 
and soles [R16-0927]. No approved or effective treatment is available.
Both UC and CD are characterised by abdominal pain, fever, bloody diarrhoea, and 
inflammatory lesions in the gastrointestinal mucosa. Current treatment options include 
aminosalicylates, glucocorticoid therapy, azathioprine, 6-mercaptopurine, and biologics 
(blocking TNF or integrin α4β7). Treatment of CD and UC is associated with a significant 
number of patients with primary and secondary non-response. In addition, treatment may be 
limited due to safety and tolerability issues. Therefore, despite progress, there remains a 
significant unmet medical need for new treatment options with an improved safety and 
efficacy profile compared with the current therapeutic standard.
1.2
DRUG PROFILE
1.2.1
Nonclinical pharmacology
BI 655130 is a humanized monoclonal antibody (mAb) of the IgG1 isotype that is directed 
against human IL36R. It is derived from a mouse antibody 81B4 (BI 674308) cloned into a 
human IgG1 Kappa backbone. The mAb uses an IgG1 that has two mutations in the Fc region 
(Leu234Ala and Leu235Ala) to reduce FcγR and complement binding. In addition, to reduce 
charge heterogeneity, the C-terminal lysine residue of the heavy chain is deleted.
For a more detailed description of the BI 655130 profile please refer to the current
Investigator’s Brochure (IB) [c03320877-04].
1.2.2
Safety pharmacology
Specific safety pharmacology studies have not been conducted with BI 655130 as it is not 
pharmacologically active in common toxicology species. Instead, studies were performed 
with BI 674304, the mouse specific anti-IL36R monoclonal antibody and used as a surrogate 
for BI 655130 (please see also Section 1.2.3). There were no clinical signs of toxicity in mice 
after the 13-week administration [c03320877-04].
1.2.3
Toxicology
As BI 655130 does not demonstrate adequate pharmacological activity in common 
toxicology species, a surrogate antibody (BI 674304) specific for mouse IL36R was 
developed and used for toxicology assessments. The toxicology package includes 4, 13 and 
26-week toxicity studies and reproductive/developmental toxicity studies with BI 674304 in 
mice. In addition, the toxicology package includes a 2-week toxicity study in mice with 
BI 655130 and local tolerance, in vitro cytokine release, and tissue cross-reactivity studies.

1.2.4
Nonclinical pharmacokinetics
The pharmacokinetics (PK) of BI 655130 was studied in cynomolgus monkeys. In mice, 
pharmacokinetic studies were performed with the mouse-specific anti-IL36R antibody, 
BI 674304 [c03320877-04].
1.2.5
Clinical experience
In Phase I, BI 655130 has been evaluated in three clinical trials: a first-in-human (FIH) SRD 
trial [c09985235-01], an MRD trial [c09105854-05], and a recently completed relative 
bioavailability study exploring the pharmacokinetics as well as safety and tolerability of a 
newly developed SC formulation (1368-0003, [c10896574-01].
FIH-Study (Trial 1368.1)
The FIH (first-in-human) trial [c09985235-01] explored safety, tolerability, 
pharmacokinetics, and pharmacodynamics of intravenously administered BI 655130 in 
healthy male subjects. Subjects received single ascending IV doses of 
 up to 
 body weight or placebo. Overall, the study included 78 male subjects with 58 
subjects treated with BI 655130 and 20 subjects treated with placebo.
At preferred term level, the most frequently reported treatment-emergent AEs were 
nasopharyngitis (BI 655130: 12/58 subjects [20.7%]; placebo: 3/20 subjects [15.0%]), 
headache (BI 655130: 5/58 subjects [8.6%]; placebo: 3/20 subjects [15.0%]), influenza like 
illness (BI 655130: 4/58 subjects [6.9%]; placebo: 2/20 subjects [10.0%]), and diarrhea 
(BI 655130: 2/58 subjects [3.4%]; placebo: 2/20 subjects [10.0%]).
There were two AEs of moderate intensity, both considered not related to the study drug, 
(injection site hematoma and headache); all remaining AEs were of mild intensity. 
There were no relevant changes compared to placebo for laboratory safety, including clinical 
chemistry, hematology, coagulation parameters, and urinalysis. Deaths, serious AEs, and 
protocol-specified AEs of special interest were not reported in this trial. No clinically relevant 
changes were observed in 12 lead ECGs, vital signs, physical exams, and cardio-monitoring.
MRD study (Trial 1368.2)
Trial 1368.2 [c09105854-05] explored the safety, tolerability, pharmacokinetics, and 
pharmacodynamics of multiple rising intravenous doses of BI. 
In total, 40 subjects entered this trial and were treated. The study consisted of a multiple dose 
part with four dose groups 
 and a single dose arm 
 A total of 32 subjects were assigned to the MRD part. In each of the 4 dose 
groups 6 subjects received BI 655130 and 2 subjects received placebo. Additional 8 subjects 
entered the SD part of the trial with 6 subjects assigned to BI 655130 and 2 subjects assigned 
to placebo [c18789185-01].
Overall, a total of 3 subjects did not complete the planned observation time according to the 
CTP. One subject of the placebo group of the MRD part of the trial withdrew consent after 
having received all 4 planned doses. Two subjects of the 
 MD BI 655130 treatment 
group discontinued treatment because of AEs: 1 subject after having received 1 dose of

BI 655130 and the other subject after having received 3 doses of 
 BI 
655130 (infusion of the third dose was stopped after 8 min). 
The frequency of subjects with at least 1 drug-related treatment-emergent AE was similar for 
the MD placebo group and the MD BI 655130 treatment groups (ranging from 16.7% to 
66.7%), and no dose-dependency was observed. The drug related AE with the highest 
incidence was headache, which was reported in 5 of 6 subjects in the 
 group. 
Additionally, gastrointestinal disorders (abdominal discomfort, diarrhoea, and nausea) 
appeared to occur more often in subjects who received BI 655130 than in subjects who 
received placebo. Infusion related reaction, decreased appetite, and anxiety were only 
observed in the 
 MD BI 655130 treatment group. In total, 2 out of the 24 subjects 
(8.3%) who received multiple doses of BI 655130 were reported with AEs leading to
discontinuation of trial drug, 1 subject with mild pyrexia after the first infusion and 1 subject 
with mild and transient infusion related reactions during the third infusion. One subject of the 
placebo group of the MRD part of the trial withdrew consent after having received all 4 
planned doses.
Deaths, serious AEs, and protocol-specified AEs of special interest were not reported in this 
trial. No relevant changes were observed in safety laboratory tests, vital signs, and ECGs. For 
further details, please refer to the final study report [c18789185-01].
Trial 1368-0003
This study explored the pharmacokinetics as well as safety and tolerability of an SC
formulation of BI 655130 at 2 different dose strengths of 
 
in an open-label, sequential group design. Furthermore, the relative bioavailability of the 
 SC dose was compared with one single 
 IV dose of BI 655130 in an open-
label, matched group design.
The study included a total of 36 healthy male and female subjects with 12 subjects per 
treatment group. 
Based on preliminary data the SC formulation is considered to be well tolerated, the 
standardised assessment of injection pain, redness, induration, swelling, heat, or other 
findings did not reveal any noteworthy changes. There were three subjects with a transient 
occurrence of redness and one subject with a swelling at injection site 30 minutes after the SC 
injection. No further local tolerability findings were reported, in particular no injection pain 
and no induration at injection site during an observation period of up to 6 months.
Regarding systemic AEs, there were no AEs of severe intensity. Deaths, serious AEs, and 
protocol-specified AEs of special interest were not reported in this trial. No relevant changes 
were observed in safety laboratory tests, vital signs, and ECGs. The clinical part of the study 
has been completed. The study report is under preparation (final safety tables available, 
[c18789185-01]).
Pharmacokinetics
The PK parameters of BI 655130 after a single IV infusion from Trial 1368.1 are shown in 
Table 1.2.5:1. BI 655130 plasma levels were first detected at a dose level of

AUC0-inf results should be considered for informational purposes only given the high %_AUC 
of extrapolated values (>50%) for the 
 dose groups. Exposure in terms of 
AUC0-tz and Cmax of BI 655130 increased with increasing dose in a greater than dose-
proportional manner from 
 and in a dose-proportional manner from 
. In the higher dose groups with apparent linear PK characteristics 
 
 the half-life (t1/2) of BI 655130 was in the range of 20.4 to 33.9 days. However, 
because of the relatively short sampling time, these values should be considered an estimate 
only.
Overall, PK data suggest target-mediated drug disposition (TMDD) kinetics for BI 655130.

Pharmacodynamics
Pharmacodynamic effects in Trials 1368.1 (SRD) and 1368.2 (MRD) were assessed by 
indirect target engagement (ITE) of IL36R by BI 55130 using an ex-vivo whole blood 
stimulation assay. Whole blood was taken before and after treatment of subjects with BI 
655130 or placebo and stimulated with IL36γ ligand. After preparation of plasma, the 
resulting production of macrophage inflammatory protein (MIP)-1β was quantified via an 
immunoassay as an exploratory biomarker. MIP-1β levels are expected to inversely correlate 
with the level of IL36R engagement by BI 655130.
In the single rising dose trial (1368.1), doses of 
 and above showed percent inhibition 
of MIP-1β of at least 94% as compared to baseline during the entire time course up to 1680 h. 
Furthermore, in the interim analysis of ITE in the multiple rising dose trial (1368.2) for dose 
groups evaluated so far, the inhibition of MIP-1β was at least 91% as compared to baseline 
during the entire time course up to 672 h for 
 dose groups as compared 
to placebo. This demonstrates that BI 655130 is on-target for the time points analyzed.
Residual Effect Period
The Residual Effect Period (REP) of BI 655130 is up to 16 weeks. This is the period after the 
last dose with measurable drug levels and/or pharmacodynamic effects still likely to be 
present.
For a more detailed description of the BI 655130 profile please refer to the current
Investigator’s Brochure (IB) [c03320877-04].

RATIONALE, OBJECTIVES, AND BENEFIT - RISK 
ASSESSMENT
2.1
RATIONALE FOR PERFORMING THE TRIAL
BI 655130 is in development for the treatment of GPP, PPP, CD, and UC. BI 655130 is 
currently in Phase II development.
In Phase I studies BI 655130 was mainly administered as intravenous infusion. However, the 
subcutaneous injection route is considered to be required to enable in upcoming therapeutic 
studies the self-administration of BI 655130 by patients. For this reason a subcutaneous 
injection formulation is undergoing clinical development.
Recently, the clinical part of a Phase 1 study (Study 1368-0003) has been completed 
exploring the characteristics of a subcutaneous formulation of BI 655130 with particular 
focus on relative bioavailability compared to an intravenous formulation. A further objective 
was the assessment of local tolerability. In this study, the relative bioavailability of a single 
SC injection containing 
of BI 655130 
was in a range of about 50% while 
relative bioavailability increased to 70% for a single SC injection of 
 of BI 655130 
 
 
To further elucidate the origin of the observed potentially dose dependent increasing 
bioavailability, the current study will compare the pharmacokinetics (PK) of a single SC 
injection of 
 of BI 655130 with the PK of two SC injections of 
 
of BI 655130 
This design will investigate the impact of local factors at the SC 
injection site on the overall exposure of BI 655130 which may contribute to the lower 
bioavailability observed in the preceding clinical study.
The current study will also investigate the impact on relative bioavailability regarding the site 
of injection (abdomen and thigh) to enable the switch of injection site if needed.
To widen the SC dose range the current study will also investigate a subcutaneous dose of 
 of BI 655130 corresponding to two single periumbilical SC injections of 
 (i.e. 
total injection volume 
 
2.2
TRIAL OBJECTIVES
The primary objective of this trial is to investigate the relative bioavailability of 
 
BI 655130 administered as two subcutaneous injections of 
 in the left and right 
periumbilical region compared to a single subcutaneous periumbilical injection of 
 
BI 655130 
The secondary objective is to investigate the relative bioavailability of a single subcutaneous 
injection of 
 BI 655130 into the thigh compared to a single subcutaneous 
periumbilical injection of
 BI 655130. 
A further objective is to investigate safety, tolerability, and pharmacokinetics of 
 BI 
655130 administered as two subcutaneous injections of
 in the left and right 
periumbilical region.

information as how to collect the data for that information, is provided in Section 5.
2.3
BENEFIT - RISK ASSESSMENT
Participation in this study is without any (therapeutic) benefit for healthy subjects. Their 
participation in the study, however, is of major importance to optimize treatment regimen of 
the subcutaneous formulation for potential use as maintenance therapy in patients. The 
subjects are exposed to the risks of the study procedures and the risks related to the exposure 
to the trial medication.
Procedure-related risks
The use of an indwelling venous catheter for the purpose of blood sampling may be 
accompanied by mild bruising and also, in rare cases, by transient inflammation of the wall of 
the vein. In addition, in rare cases a nerve might be injured while inserting the venous 
catheter, potentially resulting in paresthesia, reduced sensibility, and/or pain for an indefinite 
period. The same risks apply to veinipuncture for blood sampling.
The total volume of blood withdrawn during the entire study per subject will not exceed the 
volume of a normal blood donation
 No health-related risk to healthy subjects is 
expected from this blood withdrawal.
Drug-related risks and safety measures
The toxicology package conducted in mice with a mouse-specific antibody (BI 674304)
includes 4, 13 and 26-week toxicity studies and reproductive/developmental toxicity studies 
without any findings which would preclude clinical studies in humans (see IB 
[c03320877-04]).
The clinical safety and tolerability profile of BI 655130 was comparable to placebo in male 
subjects following once weekly intravenous doses of up to
 body weight
administered over 4 weeks. There were no deaths or other serious adverse events. There were 
no dose or exposure related abnormalities in safety laboratory parameters and no safety or 
tolerability concerns that would preclude further clinical development of BI 655130.
Recently the clinical part of an initial with a subcutaneous formulation has been completed. 
The maximum tested SC dose was
 of BI 655130 
 injection volume). The 
study did not reveal systemic or local AEs which would preclude further clinical studies with 
the SC formulation. The observed exposure at 
 following SC injection was about 6
fold lower compared to the maximum exposure in completed clinical studies with an IV 
infusion of up to 
 of BI 655130. Therefore even the planned maximum SC dose of 
 of BI 655130 is not expected to exceed exposure limits already tested in humans.
Based on studies in healthy subjects, no specific drug-related risks are anticipated. 
Nevertheless, the following safety measures are/will be applied in this study in order to 
minimize the risk for the healthy subjects:


The study will start with Dose Group 1 and 2 (periumbilical SC dose of 
 of 
BI 655130). Provided no dose limiting AEs occurred as approved 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 up to Day 10
(see Section 3.1), the study will pursue with Dose Group 3 (periumbilical SC dose of
 of BI 655130) and Dose Group 4 (SC dose of 
 of BI 655130 in the 
thigh). Dose Group 3 will be divided into 2 cohorts. In the first week, 6 subjects will 
be treated. There will be an interval of at least 1 week after start of dosing in the first 
cohort before start of dosing of the second cohort of Dose Group 3.

At any time during the ongoing study, further dosing will be stopped in case of safety 
and tolerability concerns based on the criteria defined in Section 3.1.

Monitoring of ECG, vital signs, and extensive safety laboratory testing (Table 5.2.3:1)
is conducted throughout the study.

After dosing, the subjects will stay at the site for at least 48 hours.

BI 655130 will be administered in a hospital setting and subjects will be under close 
medical observation during their hospitalisation (see Section 6.2), as well as after their 
discharge and until the end of observation period. Safety will be closely monitored 
during site visits for both expected and unexpected adverse events.
Currently there are no data available to suggest interactions of BI 655130 [c03320877-04].
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this study requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety, see also Section 5.2.2.1, adverse events of special interest.
Based on the preclinical and clinical information for BI 655130, healthy subjects are not 
expected to be exposed to undue risks and adverse events in relation to the information 
expected from this trial. Considering the medical need for the development of an effective 
and well tolerated drug for the therapy of IBD and GPP, the benefit of this trial is considered 
to outweigh the potential risks and justifies the exposure of healthy subjects.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
This study will explore the relative bioavailability, safety, and tolerability following a
subcutaneous (SC) injection of BI 655130 at different dose strengths, injection volumes, and 
injection sites: 
-
One SC injection of 
 periumbilical (Dose Group 1)
-
Two SC injections of 
each periumbilical left and right (Dose Group 2)
-
Two SC injections of 
each periumbilical left and right (Dose Group 3) 
-
One SC injection of 
 in the thigh (Dose Group 4)
The total dose in Dose Group 1, 2, and 4 is 
 of BI 655130 and the total dose in Dose 
Group 3 is 
 of BI 655130.
The study will be conducted in a single-dose, open-label, matched-group design. The 
exposure in Dose Group 1 will be used as reference to assess the relative bioavailability of 
Dose groups 2 - 4. For details refer to Section 4.1.
The study will start with Dose Group 1 and 2. After completion of treatment of the first two 
dose groups, the study will continue with Dose Group 3 and 4. At any time during the 
ongoing study, further dosing will be stopped in case of safety and tolerability concerns based 
on the pre-specified trial-specific stopping criteria (Section 3.3.4.2).
The Dose Group 3 will follow a staggered administration with treatment of 6 subjects (cohort 
A) in the first week and the remaining subjects (cohort B) from Week 2. 
A documented Safety Review of Dose Group 1 and 2 at least 10 days after last dosing in 
Dose Group 2 must take place prior to continue the study with Dose Groups 3 and 4. 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. Continuation of the study 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 8 evaluable subjects in
each of the Dose Group 1 and 2 are required to decide about continuation with the remaining 
dose groups.
The minimum data set for review consists of the following data:

AEs (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)

Vital signs 

Clinical laboratory tests 

Check of criteria for stopping subject treatment as per Section 3.3.4.1

3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
The study will be conducted according to a single-dose, open-label design with matched
groups.
The resulting group sizes (see Section 7.6) are considered to be sufficient for the exploratory
evaluation of pharmacokinetics. The assignment of matched healthy volunteers is a useful
method to control for other factors which may influence the pharmacokinetics of BI 1467335
in a renal impaired population.
The open-label treatment is not expected to bias results, since the primary endpoints are
derived from measurement of plasma concentrations of the analytes provided by a
bioanalytical laboratory. It is also considered sufficiently accurate as the trial observations are
objective (PK, laboratory) and over-reporting of AEs is unlikely.
No placebo group is included because the study is open-label with a focus on PK. Local 
tolerability is an additional objective and will remain relevant in case of dose limiting local 
AEs, whether placebo controlled or not. The systemic tolerability of BI 655130 has already
been evaluated up to 
 MRD, resulting in a far higher exposure compared to the 
expected exposure of the current study.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 48 healthy male and female subjects (12 in each dose group) will enter the 
study. They will be recruited from the volunteers' pool of the trial site. Healthy subjects 
assigned to Dose Groups 2 - 4 will be matched on an individual level for gender and body 
weight (± 10%) to subjects assigned to Dose Group 1 
, periumbilical injection).
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
Subjects will only be included into the trial, if they meet the following criteria:
1. Healthy male or female subjects according to the investigator’s assessment, based on a 
complete medical history including a physical examination, vital signs (BP, PR), 12-lead 
ECG, and clinical laboratory tests 
2. Age of 18 to 50 years (incl.) 
3. BMI of 19.0 to 29.9 kg/m2 (incl.)

>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 
marked peak aminotransferase (ALT and/or AST) elevations ≥10-fold ULN and/or needs 
to be followed up according to 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.
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 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 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 (i.e., 16 weeks, see Section 1.2.5), 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.
If it is known that a subject becomes pregnant during the trial, the subject has to be removed 
from the trial. The subject is to be followed until she has given birth or until the end of 
pregnancy. The subject’s data are to be collected until the end of the trial (last visit of last 
subject) and reported in the CTR. For reporting of pregnancy and all related events refer to 
Section 5.2.2.2.
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 are not met
3. Violation of GCP, or the CTP, or the contract with BI by the 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. Further dosing will be stopped if at least 2 subjects in one dose group show 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. Replacement of subjects should always be done in mutual agreement with the 
principal investigator. A replacement subject will be assigned a unique study subject number, 
and will be assigned to the same treatment and matching criteria as the subject he or she 
replaces.

The investigational product has been manufactured by BI Pharma GmbH & Co. KG. The 
BI 655130 molecule is a heterodimer with a molecular weight of approximately 146 kDa.
4.1.1
Identity of BI investigational product 
The characteristics of the product are given below:
Substance:
BI 655130
Pharmaceutical formulation: Solution for injection
Source:
BI Pharma GmbH & Co. KG, Germany
Unit strength:
Daily doses:
Posology:
1-0-0
Route of administration:
SC injection (periumbilical or thigh)
Duration of use:
Single dose
At the time of use, the SC solutions for dosing will be prepared as detailed in the instruction 
given in the ISF.
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 
Dose Group 1, matching subjects will be allocated to the other dose groups. Therefore, the 
allocation of subjects to dose groups is not influenced by trial personnel, but only by the 
subjects’ temporal availability. As the study includes healthy subjects from a homogenous 
population matched for gender and body weight, relevant imbalances between the dose 
groups are not expected.
The allocation of subjects will be performed prior to the administration of trial medication. 
Once a subject number has been assigned to a treatment group, it cannot be reassigned to any 
other treatment group.
4.1.3
Selection of doses in the trial
The dose of 
 of BI 655130 selected for this trial has been selected to correspond to the 
potential dose for maintenance treatment in clinical trials in patients. The highest dose tested 
in this trial 
 of BI 655130) will be included to widen the SC dose range.

Following an overnight fast of at least 10 hours, the medication will be administered. Trial 
drug will be injected subcutaneously in the abdominal region or into the thigh. Detailed 
handling instructions will be provided in the ISF. Subjects will be kept under close medical
surveillance until 48 hours following drug administration. For restrictions with regard to diet,
see Section 4.2.2.2.
4.1.5
Blinding and procedures for unblinding
No blinding will be performed. This Phase I trial will be handled in an open fashion 
throughout (that is, during the conduct, including data cleaning and preparation of the 
analysis). This is considered acceptable because the potential for bias seems to be low and 
does not outweigh practical considerations. Emergency envelopes will not be provided, since 
the treatments of all subjects are known in this open-label trial.

VARIABLES AND THEIR ASSESSMENT
5.1
EFFICACY - CLINICAL PHARMACOLOGY
5.1.1
Endpoints of efficacy
No efficacy endpoints will be evaluated in this trial.
5.1.2
Assessment of efficacy
Not applicable.
5.2
SAFETY
5.2.1
Endpoints of safety
Safety and tolerability of the investigational drug will be assessed based on: 

Adverse events (including clinically relevant findings from the physical examination)

Safety laboratory tests

Vital signs (blood pressure, pulse rate)

Local tolerability
These parameters will be evaluated in a descriptive way only, and are therefore considered to 
be ‘further parameters of interest’. A confirmatory analysis is not planned (see Section 7.3). 
5.2.2
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.
The following should also be recorded as an AE in the CRF and BI SAE form (if applicable):

Worsening of the underlying disease or of other pre-existing conditions

Chances 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 to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.

Serious adverse event
A serious adverse event (SAE) is defined as any AE which fulfils at least one of the 
following criteria:

results in death, 

is life-threatening, which 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  

requires prolongation of existing hospitalisation,

results in persistent or significant disability or incapacity, 

is a congenital anomaly/birth defect, 

is deemed serious for any other reason if it is an important medical event when based 
upon appropriate medical judgment which may jeopardise the patient and may 
require medical or surgical intervention to prevent one of the other outcomes listed in 
the above definitions. 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.
AEs considered ‘Always Serious’
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the drug and must be reported as 
described in Section 5.2.2.2, subsections ‘AEs collection’ and ‘AE reporting to sponsor and 
timelines’.
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 
defined above.
The latest list of ‘Always Serious AEs’ can be found in the eDC system, an electronic data 
capture system which allows the entry of trial data at the trial site. These events should 
always be reported as SAEs as described above.
Adverse events of special interest
The term adverse event of special interest (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. AESIs need to be reported to the sponsor’s 
Pharmacovigilance Department within the same timeframe that applies to SAEs, please see 
Section 5.2.2.2.
The AESI in this trial is hepatic injury, as defined by the following alterations of hepatic 
laboratory parameters:


an elevation of AST (aspartate transaminase) and/or ALT (alanine aminotransferase) 
≥3-fold ULN combined with an elevation of total bilirubin ≥2-fold ULN measured in 
the same blood sample, or 

aminotransferase (ALT, and/or AST) elevations ≥10 fold ULN.
These lab findings constitute a hepatic injury alert and the subjects 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 that 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 (severity) of AEs
The intensity (severity) of the AE should be judged based on the following:
Mild:
Awareness of sign(s) or symptom(s) that is/are easily tolerated
Moderate:
Sufficient discomfort to cause interference with usual activity
Severe:
Incapacitating or causing inability to work or to perform usual activities
Causal relationship of AEs
Medical judgment should be used to determine the relationship, considering all relevant 
factors, including pattern of reaction, temporal relationship, de-challenge or re-challenge, 
confounding factors such as concomitant medication, concomitant diseases and relevant 
history.
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 reduced).
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 trial drug treatment continues or remains 
unchanged. 
5.2.2.2
Adverse event collection and reporting
AE 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 carefully 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, intensity of the event, and
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 until an 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 any occurrence of cancer and related SAEs and related 
AESIs of which the investigator may become aware of by any means of 
communication, e.g. phone call. Those AEs should, however, not be reported 
in the CRF.

AE reporting to sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs that 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 the initial 
information.
Information required
All (S)AEs, including those persisting after the individual subject’s end of trial, must be 
followed up until they have resolved, have been assessed as ‘chronic’ or ‘stable’, or no 
further information can be obtained.
Pregnancy
In rare cases, pregnancy might occur in a clinical trial. Once a subject has been enrolled in 
the clinical trial and has taken trial medication, the investigator must report any drug 
exposure during pregnancy in a trial participant immediately (within 24 hours) by means of 
Part A of the Pregnancy Monitoring Form to the sponsor’s unique entry point.
Similarly, potential drug exposure during pregnancy must be reported if a partner of a male 
trial participant becomes pregnant. This requires a written consent of the pregnant partner.
The outcome of the pregnancy associated with the drug exposure during pregnancy must be 
followed up and reported to the sponsor’s unique entry point on the Pregnancy Monitoring 
Form for Clinical Trials (Part B).
The ISF will contain the Pregnancy Monitoring Form for Clinical Trials (Part A and Part B)
as well as non-trial specific information and consent for the pregnant partner.
Pregnancy itself is not to be reported as an AE. In the absence of an accompanying SAE 
and/or AESI, only the Pregnancy Monitoring Form for Clinical Trials and not the SAE form 
is to be completed. If there is an SAE and/or AESI associated with the pregnancy, an SAE 
form must be completed in addition.
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 parameters that will be determined are listed in Tables 5.2.3: 1 and 5.2.3: 2. Reference 
ranges will be provided in the ISF, Section 10.

The laboratory tests listed in Table 5.2.3: 1 and 5.2.3: 2 will be performed ZNA Klinisch 
Laboratorium, Antwerpen, Belgium with the exception of the drug screening and pregnancy 
tests. These tests will be performed at the trial site using 'Alere Triage TOX Drug Screen' and 
Alere® –HCG urine, respectively.
Laboratory data will be transmitted electronically from the laboratory to the trial site.
5.2.4
Electrocardiogram
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a
computerised electrocardiograph (e.g. MAC 5500, GE Healthcare) at the time points given in 
the Flow Chart.
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 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.
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) and the repeated ECG will be used for analysis. Additional (unscheduled) ECGs 
may be collected by the investigator for safety reasons.
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. 
5.2.5
Assessment of other safety parameters
5.2.5.1
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) will be measured by a blood pressure monitor (e.g. 
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 be made 
using the same type of blood pressure recording instrument on the same arm if possible.
5.2.5.2
Medical examinations
At screening, the medical examination will include demographics including height and body 
weight, smoking and alcohol history, relevant medical history and concomitant therapy, 
review of inclusion and exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, 
laboratory tests (including drug screen and pregnancy test), and a physical examination. The 
end of trial examination will include review of vital signs, 12-lead ECG, laboratory tests, 
recording of AEs and concomitant therapy and a physical examination with determination of 
weight.

APPROPRIATENESS OF MEASUREMENTS
All measurements performed during this trial are standard measurements and will be 
performed in order to monitor subjects’ safety and to determine 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 SC 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.
5.5
DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
Date and clock time of drug administration and pharmacokinetic sampling will be recorded in 
the CRFs.
Exact time points of plasma sampling will be derived from the electronic data capturing 
system LabPas and documented in the CRFs by the medical personnel or sent as electronic 
files to the trial data manager. The actual sampling times will be used for determination of 
pharmacokinetic parameters.

5.5.2
Methods of sample collection
5.5.2.1
Plasma sampling for pharmacokinetic analysis
For quantification of BI 655130 plasma concentrations, approximately 
 of blood will 
be taken from an antecubital or forearm vein into a K2-EDTA (dipotassium 
ethylenediaminetetraacetic acid) anticoagulant blood drawing tube at the times indicated in 
the Flow Chart under “Plasma PK”. Blood will be withdrawn by means of either an 
indwelling venous catheter or by venipuncture with a metal needle.
The K2-EDTA-anticoagulated blood samples will be mixed gently and placed on ice until 
centrifugation for about 10 min at about 2000 g to 4000 g and at approximately 4°C. The 
blood should be centrifuged to produce plasma as soon as possible after collection, but not 
later than 30 min after withdrawal. 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 
 of plasma each. The plasma samples 
will be stored in a freezer at about -70°C or below at the clinical site until shipment to the 
analytical laboratory.

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 
 of blood will be taken from a forearm vein into 
a K2-EDTA anticoagulant blood-drawing tube at the time points listed in the Flow Chart
under “Plasma ADA”. 
The K2-EDTA -anticoagulated blood samples will be mixed gently and placed on ice until 
centrifugation for about 10 min at about 2000 g to 4000 g and at approximately 4°C. The 
blood should be centrifuged to produce plasma as soon as possible after collection, but not 
later than 30 min after withdrawal. Two aliquots of EDTA plasma samples will be obtained 
in two labelled polypropylene cryotubes (label to include: BI trial number, subject number, 
visit, PTM, aliquot #1 or #2, plasma, and ADA). The two aliquots should contain 
approximately 
 of plasma each. The plasma samples will be stored in a freezer at 
about -70°C or below at the clinical site until shipment on dry ice 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 a freezer at about -70°C or below.
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 in plasma will be determined by a validated immunoassay.
5.5.3.2
Analytical determination 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).

INVESTIGATIONAL PLAN
6.1
VISIT SCHEDULE
Exact times of measurements outside the permitted time windows will be documented. The 
acceptable time windows for screening and end of trial examination are given in the 
Flow Chart.
Study measurements and assessments scheduled to occur ‘before’ trial medication 
administration on Day 1 are to be performed and completed within a 3 h-period prior to the 
trial drug administration. 
The acceptable deviation from the scheduled time for vital signs, ECG and safety laboratory
will be

± 15 min up to including 12 h

± 30 min from 12h up to including 48 h

± 120 min from 48 h up to Day 8

± 48h from Day 9 up to Day 15

± 72h from >Day 15 up to the last assessments
If scheduled in the Flow Chart at the same time as a meal, meal will be only provided after 
completion of the concomitant procedures. Furthermore, if several measurements including 
venipuncture are scheduled for the same time, vital signs and 12-lead ECG recordings have to 
be done first and 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 Report 
Planning Meeting.
6.2
DETAILS OF TRIAL PROCEDURES AT SELECTED VISITS
6.2.1
Screening period
After having been informed about the trial, all subjects will give their written informed 
consent in accordance with GCP and local legislation prior to enrolment in the study.
For information regarding laboratory tests (including drug and virus screening), ECG, vital 
signs, and physical examination, refer to Sections 5.2.3 to 5.2.5.
6.2.2
Treatment period
Study participants will be admitted to the trial site in the evening of Day -1 and kept under 
close medical surveillance for at least 48 h following drug administration. The subjects will

then be allowed to leave the trial site after formal assessment and confirmation of their 
fitness. On all other study days, the study will be performed in an ambulatory fashion.
Details on treatments and procedures of administration are described in Section 4.1.4.
For details on time points and procedures for collection of plasma samples for PK analysis, 
refer to Flow Chart and Section 5.5.2. 
The safety measurements performed during the treatment period are specified in Section 5.2
of this protocol and in the Flow Chart. For details on time points for all other trial procedures, 
refer to the Flow Chart. AEs and concomitant therapy will be assessed continuously from 
screening until the end of trial examination.
6.2.3
End of trial period
For AE assessment, laboratory tests, 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 prematurely the study before the end of the planned treatment 
period (i.e., Day 176 ±3) 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. (S)AEs persisting after subject’s end of trial must be followed 
up until they have resolved, have been sufficiently characterised, or no further information 
can be obtained.
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 trial objectives are stated in Section 2.2.
For the purpose of defining reference and test treatments, the following terminology will be 
used. The reference treatment (R) will refer to dose group 1, test treatment 1 (T1) refers to 
dose group 2, test treatment 2 (T2) refers to dose group 4 and test treatment 3 (T3) refers to 
dose group 3. 
7.1.2
Endpoints
Relative bioavailability is to be determined on the basis of the primary and secondary 
pharmacokinetic endpoints (see Section 5.5.1).
Safety and tolerability will be determined on the basis of the parameters specified in 
Section 5.2.1.
7.1.3
Model
The statistical model used for the analysis of primary and secondary endpoints will be an 
ANOVA (analysis of variance) model on the logarithmic scale. This model will include 
effects accounting for the following sources of variation: ‘treatment’ and ‘matched pair’. For 
each matched pair in the study a pair number will be assigned for analysis purpose. The 
resulting variable ‘matched pair’ will be considered as random effect.
The model is described by the following equation:
ykjm = + k + pj + eijkm, where
ykjm = logarithm of response (endpoint) measured on subject m in pair j receiving 
treatment k
= the overall mean,
k = the kth treatment effect, k=1,..,4,
pj = the jth matched pair effect,
eijkm = the random error associated with the mth subject in sequence i who received
treatment k in period j.

 ) i.i.d. and pj, eijk are independent random variables (note 
that the indices ‘B’ and ‘W’ correspond to ‘between’ pairs and ’within’ pairs variability, 
respectively).
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of the different dose groups will be estimated by the ratios of the 
geometric means (test/reference) for the primary and secondary PK endpoints. Additionally, 
their two-sided 90% confidence intervals (CIs) will be provided. This method corresponds to 
the two one-sided t-tests procedure, each at the 5% significance level. Since the main focus is 
on estimation and not testing, an acceptance range was not specified, that is, no hypothesis 
will be tested.
7.3
PLANNED ANALYSES
7.3.1
Primary analyses
The pharmacokinetic endpoints listed in 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].
Plasma concentration data and parameters of a subject will be included in the statistical
pharmacokinetic (PK) analyses if they are not flagged for exclusion due to a protocol
violation relevant to the evaluation of PK (to be decided no later than in the Report Planning
Meeting) or due to PK non-evaluability (as revealed during data analysis, based on the 
criteria specified below). Exclusion of a subject’s data will be documented in the clinical trial
report.
Relevant protocol violations may be:

Incorrect trial medication taken, that is, the subject received at least one dose of trial
medication the subject was not assigned to

Incorrect dose of trial medication taken

Use of restricted medications
Plasma concentrations and/or parameters of a subject will be considered as non-evaluable, if
for example:

The subject experiences emesis that occurred at or before 2 times median tmax of the 
respective treatment (median tmax is to be determined excluding the subjects 
experiencing emesis)

A predose concentration is >5% Cmax value of that subject

Missing samples/concentration data at important phases of PK disposition curve

The following analysis sets will be defined for this trial:

Treated set (TS):
This subject set includes all subjects from the RS who were documented to have 
received one dose of study drug. This is the full analysis set population in the sense of 
ICH-E9

Pharmacokinetic parameter set (PKS):
This subject set includes all subjects in the TS who provide at least one primary or 
secondary PK parameter that was not excluded according to the description above. 
Thus, a subject will be included in the PKS even if he/she contributes only one PK 
parameter value for one period to the statistical assessment
Point estimates of the ratios of the geometric means (test/reference) for the primary and 
secondary endpoints (see Sections 5.5.1.1 and 5.5.1.2), and their two-sided 90% confidence 
intervals (CIs) will be provided.
To this end, the PK endpoints will be log transformed (natural logarithm) prior to fitting the 
ANOVA model (cf. Section 7.1.3). For each endpoint, the difference between the expected 
means for log(T)-log(R) will be estimated by the difference in the corresponding adjusted 
means (Least Squares Means), and a two-sided 90% confidence interval based on the 
t-distribution will be computed. These quantities will then be back-transformed to the original 
scale to provide the point estimate and 90% CIs for each endpoint.
The comparisons of interest will be T1 vs. R, T2 vs. R, and T3 vs. R.
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
analysis. Safety analyses will be descriptive in nature and will be based on BI standards. No 
hypothesis testing is planned.
The analyses will be done by ‘treatment at onset’.
Treatments will be compared 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.

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 end of the residual 
effect period (see Section 1.2.5) will be assigned to the treatment period. Events after the 
residual effect period but prior to next intake or end of trial examination will be summarized 
as ‘follow-up’. The follow-up will be summarised according to previous treatment. These 
assignments including the corresponding time intervals will be defined in detail in the TSAP. 
AEs occurring after the last per-protocol contact but entered before database lock will be 
reported to drug safety only and will not be captured in the trial database.
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, severity and causal relationship of AEs will be tabulated by 
treatment, 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 as well as values defined as clinically relevant will be highlighted in the listings. 
Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data observed at screening, baseline, during the course of 
the trial and at the end-of-trial evaluation will be assessed with regard to possible changes 
compared to findings before start of treatment.
Relevant ECG findings will be reported as AEs.
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 relevant SOP of the Sponsor [001-MCS-36-472].
Individual plasma concentration data and the pharmacokinetic parameters will be tabulated,
graphically displayed and summarized by descriptive statistics. The analysis of PK endpoints 
will be based on PKS.
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.
7.4
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 drug concentration - time profiles
Handling of missing PK data will be performed according to the relevant Corporate 
Procedure 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
The study will not be randomised as individually matched subjects will be used. Thus, this 
section is not applicable.
7.6
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 4*12 = 48 subjects in the trial, because this sample size is 
considered sufficient to achieve the aims of this exploratory trial. With this sample size, the 
following precision in estimating the ratio of geometric means (test/reference) can be 
expected with 95% probability. Precision is defined as the ratio of upper CI limit to the 
relative BA estimate. Note that the precision is independent of the actual ratio of geometric 
means.

The observed inter-individual geometric coefficient of variation (gCV) in a previous trial 
(1368.3) was roughly 30% for Cmax and for AUC. For various assumptions on the gCV, 
Table 7.6: 1 provides an overview of the precision for estimating the ratio of geometric 
means (test/reference). For illustrative purposes, the expected 90% confidence intervals are 
displayed for different values of the ratios T/R of geometric means.

*Ratio of geometric means (test/reference) for a PK endpoint is defined by exp(T)/exp(R).
The 90% confidence interval limits in the table were derived by
CI limit, = exp(ln(θ) ± ω),
with θ being the ratio (T/R) on original scale and ω the distance from the estimate θ to either 
confidence interval limit on the log-scale, which was obtained from the achievable precision 
on the original scale.
The calculation was performed as described by Julious [R11-5230, Chapter 8] using R 
Version 3.4.2.
