Main criteria
for inclusion
Healthy male subjects, age of 18 to 55 years (inclusive), body mass index (BMI) of 
18.5 to 29.9 kg/m2 (inclusive)
Test product
BI 765080 powder for solution for injection/infusion, 50 mg/vial
Dose
100 mg
mode of admin.
Subcutaneous (SC) injection as bolus (Test, T)
Intravenous (IV) as 30 min infusion (Reference, R)
Duration of treatment
Single dose 
Statistical methods
Absolute bioavailability 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-test procedure, each at a 5% significance level. 
Since the main focus is on estimation and not testing, a formal hypothesis test and 
associated acceptance range is not specified. The statistical model will be an 
analysis of variance (ANOVA) on the logarithmic scale including effects for 
treatment and the matched pair. CIs will be calculated based on the residual error 
from the ANOVA.
Drug-related adverse event will be described with descriptive statistics.
Descriptive statistics will be calculated for all endpoints.

1.
INTRODUCTION
BI 765080 is intended for the treatment of chronic kidney disease (CKD). The first trial in 
humans (SRD 1450-0001 [c31414158]) is ongoing. This is the second trial in humans.
1.1
MEDICAL BACKGROUND
The incidence and prevalence of CKD can vary as a result of the underlying aetiology 
[R19-0901]. Overall, around 12% of the general population in Europe has CKD stages 3–5 
[R19-1388]. In developed countries, CKD is generally associated with diabetes, hypertension, 
old age, obesity, and cardiovascular disease.
Current treatment of CKD is based on clinical diagnosis and staging of GFR decline and 
severity of albuminuria. The current standard of care is angiotensin-converting-enzyme 
(ACE) inhibitors and angiotensin-receptor blockers (ARBs) [P11-14681].Selective 
nonsteroidal mineralo-corticoid receptor antagonists such as finerenone and sodium-glucose 
co-transporter-2 (SGLT2) inhibitors may be considered as standard of care in the future 
[P18-03010, R19-1139, R19-1356].
Although ACE inhibitors and ARBs have demonstrated efficacy in slowing the progression 
of diabetic nephropathy, it should be acknowledged that the relative risk reduction was small 
(16% in RENAAL and 19% in IDNT) for the triple composite primary endpoint of all-cause 
death, ESRD, or doubling of serum creatinine [R02-0327, R02-2101]. The residual risk is 
still considerably high. Therefore, there are high unmet needs for an effective and safe 
treatment that can further slow, halt, or reverse the progression of CKD
The Tie2 antagonist angiopoietin 2 (ANGPT2) blocks ANGPT1-mediated Tie2 activation in 
glomerular endothelial cells. In patients with diabetic nephropathy, a SNP in ANGPT2 was 
associated with a 20% elevation in the circulating protein and increased disease severity 
[R20-1041]. Glomerular ANGPT2 mRNA expression is elevated in diabetic nephropathy 
[R20-1027]. However, glomerular expression of ANGPT1, the endogenous agonist of Tie2 
[R20-1027], and circulating ANGPT1 protein [R20-1028, R20-1029] are unchanged in 
diabetic nephropathy thereby favouring ANGPT2-bound Tie2 in the context of renal disease 
progression.
Key clinical observations linking dysregulation of the ANGPT2-Tie2 pathway with CKD 
were born from trials where patients were stratified by disease severity (from stage 1 to end-
stage renal disease (ESRD) / hemodialysis (HD)) and where circulating ANGPT2 was 
progressively elevated [R20-1029] and inversely correlated with a decline in inulin-measured 
glomerular filtration rate (GFR) [R20-1030].
BI 765080 is a high affinity neutralizing antibody to ANGPT2, expected to limit antagonistic 
binding of ANGPT2 to Tie2, restore podocyte to endothelial cell cross-talk, and enable 
ANGPT1-Tie2 signalling. Enhanced Tie2 signalling via ANGPT1 is expected to stabilize the 
glomerular capillary structure, reduce endothelial activation, and restore filtration barrier

integrity. In total, these effects are expected to decrease proteinuria and preserve renal 
function resulting in a slowed disease progression in patients with CKD.
1.2
DRUG PROFILE
1.2.1
Nonclinical pharmacology 
BI 765080 binds the ANGPT2 fibrinogen-like domain (FLD) and blocks the physical 
interaction between the ANGPT2 FLD and the extracellular domain of the Tie2 receptor. 
The core safety pharmacology (neurological, cardiovascular, and respiratory functions) was 
evaluated as part of the 4-week (rat) and 13-week (monkey) GLP repeat dose toxicity studies. 
No adverse findings were associated with BI 765080 administration at dose levels up to 
100 mg/kg.
1.2.2
Toxicology
Rat and cynomolgus monkey were chosen as the rodent and non-rodent toxicology species 
due to conserved biological function of ANGPT2 among these species and humans. 4-week 
(rat) and 13-week (monkey) GLP repeat dose toxicity studies were evaluated. BI 765080 
administered up to 100 mg/kg/week was well tolerated in animals. Genetic toxicity studies 
are generally not applicable to therapeutic antibodies, as they are not expected to interact 
directly with DNA.
For a more detailed description of BI 765080 profile, please refer to the current Investigator’s 
Brochure (IB) [c30981435]
1.2.3
Clinical experience in humans
In Phase I, BI 765080 is evaluated in a first-in-human (FIH) SRD trial.
FIH-Study (Trial 1450-0001)
The FIH (first-in-human) trial [c31414158] is ongoing and explored safety, tolerability, 
pharmacokinetics, and pharmacodynamics of intravenously administered BI 765080 in 
healthy male subjects. Subjects received single ascending IV doses of 1 mg up to 
200 mg BI 765080 or placebo. Overall, the study included 48 male subjects with 36
subjects treated with BI 765080 and 12 subjects treated with placebo.
At preferred term level, all the reported treatment-emergent AEs are shown below:

herpes zoster reactivation (BI 765080: 0; placebo: 1/12 subjects [8.3 %]),
All of treatment-emergent AEs were assessed as not drug-related. There were six AEs of 
moderate intensity (four AEs with BI 765080 and two AEs with placebo). Four moderate 
AEs with BI 765080 included tooth abscess, headache post vaccine Covid-19 and upper 
respiratory infection in two subjects. Two moderate AEs with placebo included headache and 
herpes zoster reactivation. 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, and physical examinations. In addition, 
no adverse event related to local tolerability was reported.
Pharmacokinetics
The preliminary single-dose PK parameters of BI 765080 from dose groups 1 to 6 (1 to 200 
mg) are summarized in Table 1.2.3: 1. The preliminary data show that after iv infusion, 
AUC0-∞exposure increased with dose in a supraproportional fashion up to the 100 mg dose, 
consistent with target-mediated drug disposition (TMDD). Dose-adjusted AUC0-∞was about 
the same for the 200 mg dose as the 100 mg dose, suggesting TMDD may have neared 
saturation at the 100 mg dose. Cmax increased in a near dose-linear fashion at doses ≥ 10 mg.
The elimination half-life increased with increasing dose ranging from 12 hours at the 1 mg 
dose to 267 h at the 200 mg dose.

Residual Effect Period
The Residual Effect Period (REP) is the period after the last dose with measurable drug levels 
and/or PD effects still likely to be present.
For BI 765080, a REP has not yet been determined. Conservatively, an observation period of 
8 weeks has been selected, which is about 9-fold of the estimated t1/2 at 100 mg (approx. 6 
days). Therefore, the individual subject’s end of trial is on Day 56 to 59 following 
administration of investigational drug at the earliest (see Flow Chart).
1.3
RATIONALE FOR PERFORMING THE TRIAL
BI 765080 is in development for the treatment of CKD, currently in Phase I development.
In FIH BI 765080 was administered as intravenous infusion. However, the subcutaneous 
injection route is considered for the further clinical studies. For this reason absolute 
bioavailability is investigated and local tolerability is examined following subcutaneous 
injection.

1.4
BENEFIT - RISK ASSESSMENT
Participation in this clinical trial is without any (therapeutic) benefit for healthy subjects. 
Their participation, however, is of major importance for a new therapy for CKD. Subjects are 
exposed to risks of study procedures and risks related to the exposure to the trial medication.
Procedure-related risks
The use of an indwelling venous catheter or venepuncture for e.g. blood sampling may result 
in mild bruising, and in rare cases, in transient inflammation of the wall of the vein, or nerve 
injury, potentially resulting in paraesthesia, reduced sensitivity, and/or pain for an indefinite 
period.
The total volume of blood drawn per subject during the entire study will not exceed the 
volume of a normal blood donation (500 mL). No health-related risk to healthy subjects is 
expected from drawing of this volume of blood.
Drug-related risks and safety measures
The toxicity profile of BI 765080 has been assessed in repeat dose toxicity studies in rats and 
cynomolgus monkeys that included immunotoxicology and/or core safety pharmacology 
endpoints (cardiovascular, neurologic, and respiratory function), as well as in vitro cytokine
release assay and for tissue cross reactivity. No adverse findings were associated with BI 
765080 administration at dose levels up to 100 mg/kg. The nonclinical safety package for BI 
765080 supports clinical trials in humans with i.v. administration for up to 13 weeks.
The clinical safety and tolerability profile of BI 765080 was comparable to placebo in male 
subjects following intravenous doses of up to 200 mg administered as single dose. There 
were no deaths or other serious adverse events. There were no drug-related 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 765080.
Based on SRD study (1450-0001 [c31414158]) in healthy subjects, no specific drug-related 
risks are anticipated. Nevertheless, the following safety measures will be applied in this study 
in order to minimize the risk for the healthy subjects:

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 with IV will stay at the site for at least 48 hours and the 
subjects with SC will stay at the site for at least 72 hours.

BI 765080 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.
Although rare, a potential for drug-induced liver injury (DILI) is under constant surveillance 
by sponsors and regulators. Therefore, this trial requires timely detection, evaluation, and 
follow-up of laboratory alterations in selected liver laboratory parameters to ensure subjects´ 
safety; see also Section 5.2.6.1.4, adverse events of special interest.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The study will be performed as a randomised, open-label, matched parallel group trial in
healthy male subjects in order to compare subcutaneous injection administration (T) to
intravenous infusion (R). The treatments will be one single 100 mg BI 765080. For details,
refer to Section 4.1.
An overview of all relevant trial activities is provided in the Flow Chart. For visit schedule 
and details of trial procedures at selected visits, refer to Sections 6.1 and 6.2, respectively.
3.2
DISCUSSION OF TRIAL DESIGN, INCLUDING THE CHOICE OF 
CONTROL GROUP
This study will explore the absolute bioavailability, safety, tolerability and 
pharmacodynamics following intravenous (IV) infusion or subcutaneous (SC) injection of BI 
765080 in matched pairs of healthy male subjects (matching is done based on age and body 
weight, see Section 3.3). By dosing test and reference treatment to a matched pair on the 
same day the influence of confounding factors can be reduced to a minimum.
The trial will be conducted open-label. Blinding is not possible because the treatments are 
distinguishable. The open-label treatment is not expected to bias results, since the study 
endpoints are derived from measurement of plasma concentrations of the analyte, which are 
provided by a bioanalytical laboratory that is blinded to treatment allocation.
3.3
SELECTION OF TRIAL POPULATION
It is planned that 28 healthy male subjects (14 subjects with IV and 14 subjects with SC) will 
enter the study to have at least 12 evaluable subjects available in each group. They will be 
recruited from the volunteers' pool of the trial site.
Participants in SC and IV groups will be matched for age (18-36 or 37-55 years at screening) 
and body weight (±10% inclusive). That means, that the 2 subjects of one matched pair are 
either 18-36 years (inclusive) or 37-55 years old (inclusive) and that the difference of their 
body weight does not exceed 10% (e.g. 80 kg and 88 kg).
Only Caucasian male subjects will be included in the study.
A log of all subjects enrolled into the trial (i.e. who have signed informed consent) will be 
maintained in the ISF irrespective of whether they have been treated with investigational drug 
or not.
3.3.1
Main diagnosis for trial entry
The trial will be performed in healthy subjects.
3.3.2
Inclusion criteria
Subjects will only be included in the trial if they meet the following criteria:

requirements, or has a condition that would not allow safe participation in the study 
23. Male subjects with WOCBP partner who are unwilling to use a highly effective 
method of birth control from time point of administration of trial medication until 90 
days thereafter. Highly effective methods of birth control are:
- Male subject is sexually abstinent
- Male subjects is vasectomised (vasectomy at least 1 year prior to enrolment), plus 
condom in male subject
- Use of intrauterine device (IUD) or intrauterine hormone-releasing system (IUS) 
by female partner
- Use of progestogen-only hormonal contraception by female partner that inhibits 
ovulation (only injectables or implants), plus condom in male subject
- Use of combined (estrogen and progestogen containing) hormonal contraception 
by female partner that prevents ovulation (oral, intravaginal or transdermal), plus 
condom in male subject
- Female partner is surgically sterilised (including hysterectomy)
- Female partner is postmenopausal, defined as no menses for 1 year without an 
alternative medical cause)
Subjects are required to use condoms to prevent unintended exposure of the partner 
(both, male and female) to the study drug via seminal fluid. Male subjects should use 
a condom throughout the study and for 90 days after investigational medicinal product 
(IMP) administration.
Alternatively, true abstinence is acceptable when it is in line with the subject’s 
preferred and usual lifestyle.
If a subject is usually not sexually active but becomes active, with their partner, they 
must comply with the contraceptive requirements detailed above.
Male subjects should not donate sperm for the duration of the study until at least 90 days after 
IMP administration. 
In addition, the following SARS-CoV-2-specific exclusion criteria apply:
24. A positive PCR test for SARS-CoV-2 or clinical symptoms suggestive for this disease 
prior to the admission.

For study restrictions, refer to Section 4.2.2.
3.3.4
Withdrawal of subjects from treatment or assessments
Subjects may discontinue trial treatment or withdraw consent to trial participation as a whole 
(‘withdrawal of consent’) with very different implications; please see Sections 3.3.4.1 and 
3.3.4.2 below.
If a subject is removed from or withdraws from the trial prior to the administration of trial 
medication, the data of this subject will not be entered in the case report form (CRF) and will 
not be reported in the clinical trial report (CTR). If a subject is removed from or withdraws 
from the trial after the administration of trial medication, this will be documented and the 
reason for discontinuation must be recorded in the CRF; in addition, the data will be included 
in the CRF 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 CRF. If the discontinuation occurs 
before the end of the REP (see Section 1.2.4 ), the discontinued subject should if possible be 
questioned for AEs and concomitant therapies at or after the end of the REP in order to 
ensure collection of AEs and concomitant therapies throughout the REP, if not contrary to 
any consent withdrawal of the subject.
3.3.4.1
Discontinuation of trial treatment
An individual subject will discontinue trial treatment if:
1. The subject wants to discontinue trial treatment, without the need to justify the 
decision
2. The subject has repeatedly shown to be non-compliant with important trial procedures 
and, in the opinion of both, the investigator and sponsor representative, is not willing 
or able to adhere to the trial requirements in the future.
3. The subject needs to take concomitant medication that interferes with the 
investigational medicinal product or other trial treatment
4. The subject can no longer receive trial treatment for medical reasons (such as surgery, 
adverse events [AEs], or diseases)
5. The subject has an elevation of AST and/or ALT ≥3-fold ULN and an elevation of 
total bilirubin ≥2-fold ULN (measured in the same blood sample) and/or needs to be 
followed up according to the DILI checklist provided in the ISF
6. An AE or clinically significant laboratory change or abnormality occurs that the 
investigator assesses as warranting discontinuation of treatment. This may include 
cases of sustained symptomatic hypotension (BP <90/50 mmHg) or hypertension (BP 
>180/100 mmHg), clinically relevant changes in ECG requiring intervention, or 
unexplained hepatic enzyme elevations at any time during the trial

In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.
If new efficacy or safety information becomes available, Boehringer Ingelheim will review
the benefit-risk-assessment and, if needed, pause or discontinue the trial treatment for all
subjects or take any other appropriate action to guarantee the safety of the trial subjects.
3.3.4.2
Withdrawal of consent to trial participation
Subjects may withdraw their consent to trial participation at any time without the need to 
justify the decision. If a subject wants to withdraw consent, the investigator should be 
involved in the discussion with the subject and explain the difference between trial treatment 
discontinuation and withdrawal of consent to trial participation, as well as explain the options 
for continued follow up after trial treatment discontinuation, please see Section 3.3.4.1 above
3.3.4.3
Discontinuation of the trial by the sponsor
Boehringer Ingelheim reserves the right to discontinue the trial at any time for any of the 
following reasons (if reasons 4 and/or 5 are met, the trial should be discontinued 
immediately):
1. Failure to meet expected enrolment goals overall or at a particular trial site
2. The sponsor decides to discontinue the further development of the investigational 
product
3. Deviation from GCP, or the CTP, or the contract with BI impairing the appropriate 
conduct of the trial.
4. New toxicological findings, serious adverse events, or any safety information
invalidating the earlier positive benefit-risk-assessment. 
5. More specifically, the trial will be terminated if more than 50% of the subjects have
drug-related and clinically relevant adverse events of moderate or severe intensity, or 
if at least 1 drug-related serious adverse event is reported
6. Further dosing will be stopped if at least 2 subjects at one group (14 subjects) have 
relevant individual QT prolongations, i.e. a QTc increase of greater than 60 ms from 
baseline in connection with absolute QT or QTc greater than 500 ms, as confirmed by 
a repeat ECG recording
7. Occurrence of severe non-serious adverse events considered as drug-related by the 
investigator in 2 subjects of one group (14 subjects)
The investigator / trial site will be reimbursed for reasonable expenses incurred in case of 
trial termination (except if item 3 applies).
3.3.5
Replacement of subjects
In case more than two subjects per treatment group do not complete the trial, the Clinical trial 
leader together with the Trial Pharmacokineticist and the Trial Statistician are to decide, if 
and how many subjects will be replaced. A replacement subject will be assigned a unique

potential dose for maintenance treatment in clinical trials in patients.
4.1.3
Method of assigning subjects to treatment groups
Prior to the start of the study, subjects willing to participate in this study will be recruited to
treatment groups according to their temporal availability (this includes the ability to 
participate as well in the IV-arm as in the SC-arm). From the eligible subjects matched pairs 
(based on age and body weight, see Section 3.3) are formed by the investigator.
The randomisation list will be provided to the trial site in advance. Subjects are then assigned 
to treatment according to the randomization list with a block size of 2. The allocation of these 
two random numbers to one matched pair of subjects will be done by drawing lots in the 
morning of Day 1.
Once a random number has been assigned to a subject, it cannot be reassigned to any other 
subject.
4.1.4
Drug assignment and administration of doses for each subject
The treatments to be evaluated are outlined in Table 4.1.4: 1 below. Each subject will receive 
one single dose of trial medication. Detailed instructions for the dilution of the trial product, 
the preparation of the IV infusion and SC injection solutions, the volume to be administered 
and the infusion/injection time is provided in Appendix 10.1. In the subjects with IV, the 
infusion solution will be intravenously administered over 30 minutes.

infusion will be recorded. Detailed handling instruction for the infusion see Appendix 10.1.
Subjects will be kept under close medical surveillance until 48 h following drug 
administration. Day 3, subjects will be discharged from the trial site and further assessments 
will be conducted in an ambulatory fashion. For restrictions regarding diet, see also Section 
4.2.2.2.
The administration of the trial medication will be done under supervision of the investigating 
physician or a designee. For drug administration, the so-called four-eye principle (two-person 
rule) should be applied. For this, one authorised employee of the trial site should witness the 
administration of trial medication, and – if applicable – its preparation (e.g. reconstitution), if 
correct dosage cannot be ensured otherwise. For the purpose of drug accountability, the 
infusion set will be weighed before and after drug administration.
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 is low and does not 
outweigh practical considerations.
Emergency envelopes will not be provided, because the trial medication is known to 
investigators and subjects.
PK samples will be labelled in such a way that treatment allocation cannot be derived by the
analytical site.
4.1.6
Packaging, labelling, and re-supply
The investigational medicinal products will be provided by BI. They will be packaged and 
labelled in accordance with local law and the principles of Good Manufacturing Practice. 
For details of packing and the description of the label, refer to the ISF.
The name, address and telephone number of the trial site are provided in the subject 
information form. The EudraCT number is indicated on the title page of this protocol as well 
as on the subject information and informed consent forms.
No re-supply is planned.
4.1.7
Storage conditions
Drug supplies will be kept in their original packaging and in a secure limited access storage 
area in accordance with the recommended (labelled) storage conditions. If necessary, a 
temperature log must be maintained to make certain that the drug supplies are stored at the 
correct temperature. If the storage conditions are found to be outside the specified range, the 
local clinical monitor (as provided in the list of contacts) is to be contacted immediately.

ASSESSMENT OF SAFETY
5.2.1
Physical examination
At screening, the medical examination will include demographics, height and body weight, 
smoking and alcohol history (alcohol history results not mandatory to be entered into CRF or 
to be reported), relevant medical history and concomitant therapy, review of inclusion and 
exclusion criteria, review of vital signs (BP, PR), 12-lead ECG, laboratory tests, and a 
physical examination. At the end of trial examination, it will include review of vital signs, 12-
lead ECG, laboratory tests, and a physical examination.
5.2.2
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 
(Dinamap Pro 100, 
) 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.
Oral body temperature will be measured using a standard device if it is still needed in the 
current status of pandemic.
5.2.3
Safety laboratory parameters
For the assessment of laboratory parameters, blood and urine samples will be collected by the 
trial site at the times indicated in the Flow Chart after the subjects have fasted for at least 10 h
(Subjects are advised to come fasted overnight when visiting in the morning, 4h when 
visiting in the afternoon for the screening) . For retests, at the discretion of the investigator or 
designee, overnight fasting is not required.
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.

procedures scheduled for the same time to avoid compromising ECG quality. 
All ECGs will be recorded, interpreted and stored electronically at the site. Electrode 
placement will be performed according to the method of Wilson, Goldberger and Einthoven 
modified by Mason and Likar (hips and shoulders instead of ankles and wrists). 
All locally printed ECGs will be evaluated by the investigator or a designee. Abnormal 
findings will be reported as AEs (during the trial) or baseline conditions (at screening) if 
assessed to be clinically relevant by the investigator. Any ECG abnormalities will be 
carefully monitored and, if necessary, the subject will be removed from the trial and will 
receive the appropriate medical treatment. 
ECGs may be repeated for quality reasons (for instance, due to alternating current artefacts, 
muscle movements, or electrode dislocation) and the repeated ECG will be used for analysis. 
Additional (unscheduled) ECGs may be collected by the investigator for safety reasons. 
5.2.5
Other safety parameters
5.2.5.1
Local tolerability
Local tolerability will be assessed by the investigator on the basis of swelling, induration, 
heat, redness, pain, and other findings.

Assessment of adverse events
5.2.6.1
Definitions of adverse events
5.2.6.1.1
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 

Changes in vital signs, ECG, physical examination, and laboratory test results, if they 
are judged clinically relevant by the investigator
If such abnormalities already pre-exist prior to trial inclusion, they will be considered as 
baseline conditions and should be collected in the eCRF only.
5.2.6.1.2
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

5.2.6.1.3
AEs considered ‘Always Serious’
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. A copy of the latest list of
‘Always Serious AEs’ will be provided upon request. These events should always be reported
as SAEs as described Section 5.2.6.2.
Cancers of new histology and exacerbations of existing cancer must be classified as a serious 
event regardless of the time since discontinuation of the trial medication and must be reported 
as described in 5.2.6.2, subsections ‘AE Collection’ and ‘AE reporting to sponsor and 
timelines’.
5.2.6.1.4
Adverse events of special interest
The term adverse events 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 5.2.6.2.2.
The following are considered as AESIs:

Potential severe DILI
A potential severe Drug Induced Liver Injury (DILI) that requires follow-up is defined 
by the following alterations of hepatic laboratory parameters: 
o
An elevation of AST (aspartate aminotransferase) 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 in samples drawn within 
30 days of each other, or
o
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.
No other AESIs have been defined for this trial.

5.2.6.1.5
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
5.2.6.1.6
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

There is an 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

5.2.6.2
Adverse event collection and reporting
5.2.6.2.1
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
time, 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.

5.2.6.2.2
AE reporting to the sponsor and timelines
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form. 
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
5.2.6.2.3
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 sufficiently assessed as ‘chronic’ or ‘stable’, 
or no further information can be obtained.
5.2.6.2.4
Pregnancy
Once the male subject has been enrolled in the clinical trial and has taken trial medication, 
and if a partner of the male trial participant becomes pregnant, the investigator must report 
any drug exposure during pregnancy in a partner of the male trial participant immediately 
(within 24 hours) by means of Part A of the Pregnancy Monitoring Form to the sponsor’s 
unique entry point, after 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.
As 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.

DRUG CONCENTRATION MEASUREMENTS AND 
PHARMACOKINETICS
5.3.1
Assessment of pharmacokinetics
For the assessment of pharmacokinetics, blood samples will be collected at the time points 
indicated in the Flow Chart. Date and clock times of drug administration and
pharmacokinetic sampling will be recorded in the CRFs. The actual sampling times will be 
recorded and used for determination of pharmacokinetic parameters.

5.3.2
Methods of sample collection
5.3.2.1
Blood sampling for pharmacokinetic analysis
For quantification of BI 765080 concentrations in serum, 3mL of blood will be drawn from 
an antecubital or forearm vein into a serum collection tube (SST II Advance tube or 
equivalent) at the times indicated in the Flow Chart. Blood will be withdrawn by means of 
either an indwelling venous catheter or by venepuncture with a metal needle.
The sample tubes will be inverted six times without shaking and left upright for at least 30 
minutes to allow the sample to thoroughly clot. Serum is prepared by centrifugation for 
approximately 10 -15 minutes at approximately 1500 g to 2000 g at room temperature. 
Immediately transfer at least 0.5 mL serum from the collection tube into each of the labelled 
cryotubes. 
At a minimum, the sample tube labels should list BI trial number, subject number, visit, and 
planned sampling time, aliquot #1 or #2, serum, and PK. 
The time each aliquot was placed in the freezer will be documented. Until transfer on dry ice 
to the analytical laboratory, the aliquots will be stored upright at approximately -70°C/-94ºF 
or below at the trial site. The second aliquot will be transferred to the analytical laboratory 
after the bioanalyst has acknowledged safe arrival of the first aliquot. At the analytical 
laboratory, the serum samples will be stored at approximately -70°C/-94ºF or below until 
analysis.
After completion of the trial, the serum 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 CTR is 
archived.

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 pharmacokinetic parameters 
in an appropriate way. The scheduled measurements will allow monitoring of changes in vital 
signs, standard laboratory values, ECG parameters, and local tolerability 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 IV and SC administered drug, and are widely used 
in clinical trials. The pharmacokinetic parameters and measurements outlined in Section 5.4
are generally used assessments of drug exposure.

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 the end of trial examination are provided 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 (including blank values for PK).
The acceptable deviation from the scheduled time for vital signs, ECG, and laboratory tests
will be:

± 30 min up to and including 48 h

± 120 min from 48 h up to Day 8

± 4h from Day 8 onwards up to the last measurements
The tolerance for blood sampling for PK,
will be:

±1 min up to and including 30 min

±5 min from 30 min up to and including 12 h

±15 min from 12 h up to and including 48 h

±60 min from 48 h up to Day 8

±4h from Day 8 onwards up to the last measurements
If scheduled in the Flow Chart at the same time as a meal, blood sampling, vital signs, and 
12-lead ECG recordings have to be done first. Furthermore, if several measurements 
including venepuncture are scheduled for the same time, venepuncture should be the last of 
the measurements due to its inconvenience to the subject and possible influence on 
physiological parameters.
For planned blood 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 
the determination of pharmacokinetic parameters.
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

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
Each subject will receive one dose of trial medication (BI 765080) at Visit 2. 
Trial medication will be administered as IV infusion or SC injection by the investigating 
physician or
designee. Details on treatments and procedures of administration are 
described in Section 4.1.4.
Study participants will be admitted to the trial site on Day -1 and kept under close medical 
surveillance for at least 48 h (IV group) or 72 h (SC group) following drug administration. 
The subjects will then be allowed to leave the trial site after formal assessment and 
confirmation of their fitness by the investigator or
designee. On all other study days, 
subjects will be treated in an ambulatory fashion.
For details on time points and procedures for collection of blood samples for PK analysis, 
refer to Flow Chart and Section 5.3.2.
The safety measurements performed during the treatment period are specified in Section 5.3
of this protocol and in the Flow Chart. For details on times of 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
Follow-up period and trial completion
For AE assessment, laboratory tests, recording of ECG and vital signs, and physical 
examination during the follow-up period, see Sections 5.2.2 to 5.2.5.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the EoTrial Visit.
If needed in the opinion of the investigator, additional visits may be scheduled after the 
EoTrial Visit for continued safety monitoring.
All abnormal values (including laboratory parameters) that are assessed as 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 a subject’s EoTrial Visit must be 
followed until they have resolved, have been sufficiently characterised, or no further 
information can be obtained.

STATISTICAL METHODS AND DETERMINATION OF
SAMPLE SIZE
7.1
STATISTICAL DESIGN – MODEL
The main objective of this trial is to investigate the absolute bioavailability of (SC) injection
of100 mg BI 765080 (Test, T) compared with IV dose of 100 mg BI 765080 (Reference, R) 
following administration on the basis of the primary and secondary safety and 
pharmacokinetic endpoints, as listed in Section 2.1.2 and 2.1.3. The trial is designed to allow 
inter-subject comparisons and will be evaluated statistically by use of a linear model for 
logarithmically transformed PK endpoints and descriptive analysis for AEs.
The assessment of safety and tolerability as well as local tolerability is a further objective of 
this trial, and will be evaluated by descriptive statistics for the parameters specified in Section 
2.2.2.2 and 2.2.2.3.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The absolute bioavailability of SC injection compared with IV dose will be estimated by the 
ratios of the geometric means (test/reference), and their corresponding 2-sided 90% 
confidence intervals (CIs) will be provided. This method corresponds to the two one-sided t-
test procedure, each at the 5% significance level. Since the main focus is on estimation and 
not testing, a formal hypothesis test and associated acceptance range is not specified.
7.3
PLANNED ANALYSES
Analysis sets
Statistical analyses will be based on the following analysis sets:

Treated set (TS): The treated set includes all subjects who were allocated and treated 
with at least one dose of study drug. The treated set will be used for safety analyses.
Pharmacokinetic parameter analysis set (PKS): This set includes all subjects in the 
treated set (TS) who provide at least one PK endpoint that was defined as primary or 
secondary and was not excluded due to a protocol violation relevant to the evaluation 
of PK or due to PK non-evaluability (as specified in the following subsection 
‘Pharmacokinetics’). Thus, a subject will be included in the PKS, even if he/she 
contributes only one PK parameter value to the statistical assessment. Descriptive and 
model based analyses of PK parameters will be based on the PKS.
Adherence to the protocol will be assessed by the trial team. Important protocol violation 
(IPV) categories will be specified in the IPD specification file prior to trial initiation, IPVs 
will be identified no later than in the Report Planning Meeting, and the IPV categories will be 
updated as needed.

Pharmacokinetics
The pharmacokinetic parameters listed in Section 2.1 for drug BI 765080 will be calculated 
according to the relevant SOP of the Sponsor (current version). 
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 CTR.
Relevant protocol violations may be

Incorrect trial medication taken, i.e. 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

A predose concentration is >5% Cmax value of that subject

Missing samples/concentration data at important phases of PK disposition curve.
Plasma concentration data and parameters of a subject which is flagged for exclusion will be 
reported with its individual values but will not be included in the statistical analyses. 
Descriptive and inferential statistics of PK parameters will be based on the 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). 
7.3.1
Primary endpoint analyses
Primary analyses
The statistical model used for the analysis of the primary endpoints will be an analysis of 
variance (ANOVA) model on the logarithmic scale. That is, the PK endpoints will be log-
transformed (natural logarithm) prior to fitting the ANOVA model. This model will include 
effects accounting for the following source of variation: treatment and matching pair. The 
effect of treatment will be considered as fixed. 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:
ykm = + k + sm + ekm, where
ykm = logarithm of response measured on subject m receiving treatment k,

Point estimates for the ratios of the geometric means (test/reference) for the primary 
endpoints (see Section 2.1) and their two-sided 90% confidence intervals (CIs) will be 
provided.
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).
Additionally their two-sided 90% confidence intervals will be calculated based on the 
residual error from the ANOVA and quantiles from the t-distribution. These quantities will 
then be back-transformed to the original scale to provide the point estimate and 90% CIs for 
each endpoint.
In addition to the model based approach all parameters will be calculated and analysed 
descriptively.
7.3.2
Secondary endpoint analyses
The secondary PK endpoints (refer to Section 2.1.3) will be calculated according to the BI

7.3.4
Safety analyses
Safety will be analysed based on the assessments described in Section 2.2.2.2 and 2.2.2.3. All 
treated subjects (TS, refer to Section 7.2) will be included in the safety analysis. Safety 
analyses will be descriptive in nature and based on BI standards. No hypothesis testing is 
planned.
For all analyses, the treatment actually administered (= treatment at onset) to the subject will 
be used (any deviations from the treatment will be discussed in the minutes of the Report 
Planning Meeting).
Treatments will be compared in a descriptive way. Tabulations of frequencies/proportions 
will be used to evaluate 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 the screening period, those between first trial medication intake and end of 
trial examination (including the anticipated REP (see Section 1.2.3)) will be assigned to the 
treatment period. These assignments including the corresponding time intervals will be 
defined in detail in the TSAP. Note that AEs occurring after the last per protocol contact but 
entered before final database lock will be reported to Pharmacovigilance only and will not be 
captured in the trial database.
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 5.2.6.1), and 
other significant AEs (according to ICH E3) will be listed separately.
Previous and concomitant therapies will be presented per treatment group without 
consideration of time intervals and treatment periods.
Laboratory data will be compared to their reference ranges. Values outside the reference 
range as well as values defined as possibly clinically significant will be highlighted in the 
listings. Additionally, differences from baseline will be evaluated.
Vital signs or other safety-relevant data will be assessed with regard to possible on-treatment 
changes from baseline.
Relevant ECG findings will be reported as AEs.

7.4
INTERIM ANALYSES
No formal interim analysis is planned. A preliminary analysis of PK parameters and safety 
may be performed, if requested by the Clinical Trial Leader, the investigator, or Trial Clinical 
Pharmacokinetics.
7.5
HANDLING OF MISSING DATA
7.5.1
Safety
It is not planned to impute missing values for safety parameters.
7.5.2
Pharmacokinetics
Handling of missing PK data will be performed according to the relevant Corporate 
Procedure (current version).
PK parameters that cannot be reasonably calculated based on the available drug 
concentration-time data will not be imputed.
7.6
RANDOMISATION
This is a randomized trial. Consecutive subject numbers will be assigned via the eDC system. 
Subjects will be randomized within each matched pair in a 1:1 ratio (IV to SC).
The sponsor will arrange for the randomization as well as packaging and labelling of trial 
medication. The randomization list will be generated using a validated system that uses a 
pseudo-random number generator and a supplied seed number so that the resulting allocation 
is both reproducible and non-predictable.
The randomization list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).
7.7
DETERMINATION OF SAMPLE SIZE
It is planned to enter a total of 28 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 geometric coefficient of variation (gCV) for BI 765080 in the 1450-0001 trial
[c31414158] was roughly 14% for Cmax and 25% for AUC.

*Ratio of geometric means (test/reference) for a PK endpoint is defined by exp(T)/exp(R).
The expected 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] using R Version 4.0.1.

DATA QUALITY ASSURANCE
A risk-based approach is used for trial quality management. It is initiated by the assessment 
of critical data and processes for trial subject protection and reliability of the results as well as 
identification and assessment of associated risks. An Integrated Quality and Risk 
Management Plan documents the rationale and strategies for risk management during trial 
conduct including monitoring approaches, vendor management and other processes focusing 
on areas of greatest risk. 
Continuous risk review and assessment may lead to adjustments in trial conduct, trial design 
or monitoring approaches. 
A quality assurance audit/inspection of this trial may be conducted by the sponsor, sponsor’s 
designees, or by IRB / IEC or by regulatory authorities. The quality assurance auditor will 
have access to all medical records, the investigator’s trial-related files and correspondence, 
and the informed consent documentation of this clinical trial.
8.3
RECORDS
CRFs for individual subjects will be provided by the sponsor. For drug accountability, refer 
to Section 4.1.8.
8.3.1
Source documents
In accordance with regulatory requirements, the investigator should prepare and maintain 
adequate and accurate source documents and trial records for each trial subject that include 
all observations and other data pertinent to the investigation. Source data as well as reported 
data should follow the ‘ALCOA principles’ and be attributable, legible, contemporaneous, 
original, and accurate. Changes to the data should be traceable (audit trail).
Data reported on the CRF must be consistent with the source data or the discrepancies must 
be explained.
Before providing any copy of subjects’ source documents to the sponsor, the investigator 
must ensure that all subject identifiers (e.g., subject’s name, initials, address, phone number, 
and social security number) have properly been removed or redacted to ensure subject 
confidentiality.
If the subject is not compliant with the protocol, any corrective action (e.g. re-training) must 
be documented in the subject file.
For the CRF, data must be derived from source documents, for example:

Subject identification: sex, year of birth (in accordance with local laws and 
regulations)

Subject participation in the trial (substance, trial number, subject number, date subject 
was informed)

Dates of subject’s visits, including dispensing of trial medication

Preparation of the study medication – IV Dose
10.1.3.3.1 Reconstitution of the lyophilized powder
1. Attach a 3 mL syringe to the bottle containing water for injection (WFI) and withdraw 
1.2 mL WFI.
2. Attach a 20G needle to the syringe and adjust the volume to 1.1 mL and gently inject 
the complete content of the syringe through the stopper, to the wall of the vial 
containing BI 765080 powder for solution for injection / infusion.
3. Discard needle and syringe and swirl the vial gently until the lyophilizate is dissolved 
and homogenized. Do not shake. Avoid the generation of foam. The full 
reconstitution should be finished within 10 minutes. The resulting concentration is 50 
mg/mL.
4. In case foam generation during reconstitution wait with further processing until foam 
has settled. This should take not more than 60 min. 
10.1.3.3.2 Dilution Procedure – 100 mg IV dose

2. Pool 2 mL of reconstituted drug product in a 3 mL syringe.
3. Combine both syringes with a syringe adapter / discofix connector and mix the 
content of the syringes by gently transferring back and forth times. The resulting 
concentration is 2 mg/mL.
4. Collect the complete volume in the 50 mL syringe. Make sure that the complete 
volume has been transferred to the 50 mL syringe prior disconnecting the smaller 
syringe and the adapter. Lock the syringe using a syringe closure. 
The site may prepare syringes containing an overfill as per site standard policies. The overfill 
is required in order to accommodate the dead volume of the infusion set.
