Clinical phase
I
Trial rationale
Trial Parts 1 and 2:
To define the relative bioavailability of two tablet strengths of Trial Formulation 1 
(TF1) used in previous Phase 1 and Phase 2 trials and of the newly developed 
intended Commercial Formulations (iCF) for Phase 3 in order to bridge 
pharmacokinetic and safety data between the formulations and secure Phase 3 
dosing. The 50 mg tablet formulations will be compared in Part 1, the 100 mg tablet 
formulations in Part 2. 
Trial Part 3:
To determine clinically relevant specifications for BI 730357 particle size in the 
100 mg iCF (coarse milled active pharmaceutical ingredient (API) vs. unmilled API 
vs. regularly milled API) and to show in vivo relevance of the selected in vitro
dissolution method for the iCF. 
Trial objective
Trial Parts 1 and 2:
To investigate the relative bioavailability of two tablet strengths (50 mg and 
100 mg) of the intended Commercial Formulation of BI 730357 (Test, T) versus the 
corresponding tablet strengths of Trial Formulation 1 (Reference, R)
Trial Part 3: 
To investigate the relative bioavailability of two iCF side batches of BI 730357 with 
coarse milled API (Testcoarse milled, Tc) and unmilled API (Testunmilled, Tu), 
respectively, versus the final iCF batch of BI 730357 with regularly milled API 
(Reference, R)
Trial design
Parts 1 & 2: Randomized, open-label, single-dose, 2-way crossover design
Part 3: 
Randomized, open-label, single-dose, 3-way crossover  design

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 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 ‘subjects’ and 
‘treatment’. CIs will be calculated based on the residual error from the ANOVA.
Descriptive statistics will be calculated for all endpoints.

1.3
RATIONALE FOR PERFORMING THE TRIAL
Parts 1 and 2 of this trial are designed to investigate the relative bioavailability of two tablet 
strengths of a newly developed tablet formulation (iCF batch 1 and batch 2) of BI 730357 
compared to the corresponding strengths of TF1 following oral administration in healthy 
male and female subjects. TF1 has already been administered and investigated in previous 
clinical trials. iCF is the anticipated formulation for Phase 3 and, if applicable, later in clinical 
practice. To allow the prediction of safety and pharmacokinetics in Phase 3 and clinical 
practice, comparable pharmacokinetic data between TF1 and iCF are considered essential. 
PK data from SRD trial 1407.1 and MRD trial 1407-0002 revealed non-linear kinetics of 
BI 730357 with a less-than-dose-proportional increase of AUC0-∞and Cmax. Therefore, in 
accordance with regulatory guidelines [R05-1094; R10-2509] a low dose of 50 mg (with 
50 mg formulations in Part 1), and a high dose of 200 mg (with 100 mg formulations in 
Part 2), corresponding to doses at the bottom and top end of the anticipated dose range to be 
tested in Phases 2 and 3, have been selected. As 50 mg was seen at the top of the dose 
proportional range, results obtained with 50 mg in this trial will also cover lower doses.
The aim of Part 3 is to determine clinically relevant specifications for BI 730357 particle size 
in the 100 mg iCF and to show in vivo relevance of the selected in vitro dissolution method 
for the iCF. The final iCF tablet with regularly milled API showed the fasted dissolution 
behavior whereas the iCF with the unmilled API showed the slowest dissolution. A relative 
bioavailability comparison using these two extremes (i.e. the final batch with regularly milled 
API and a side batch with unmilled API) and a side batch in between (e.g. with coarse milled 
API) would be the best option to achieve this aim.
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 the development of BI 730357.

Subjects are exposed to risks of study procedures and risks related to the exposure to the trial 
medication.
1.4.1
Expected benefit to the target population
 
 
filling an 
unmet medical need for the introduction of new, efficacious oral treatment options in the 
treatment of psoriasis 
1.4.2
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 syncope, in transient inflammation of the wall of the 
vein, or nerve injury, potentially resulting in paraesthesia, reduced sensibility, and/or pain for 
an indefinite period.
ECG electrodes may cause local and typically transient skin reactions.
The total volume of blood withdrawn 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 withdrawal of this volume of blood.
1.4.3
Drug-related risks and safety measures
As the nature of the target and the mechanism of action of BI 730357 are well understood 
from pre-clinical studies, comparable compounds have been tested by other companies before 
(although not a lot of published data are available), and the animal models are believed to be 
predictive for the effects in humans, BI 730357 is not seen as a high-risk compound.
Single dose administration of BI 730357 is supported up to 800 mg by preclinical, as well as 
clinical safety data from first-in-human trial 1407.1 (see Section 1.2.2). In trial 1407.1, 
administration of a 800 mg tablet under fed (high-fat) conditions resulted in exposures 
 
This was 2.9-fold and 4.1-
fold below the Cmax and AUC0-24 respectively at the combined NOAEL for male and female 
dogs after 13 weeks of treatment (see Section 1.2.1.3). 
Since preclinical data indicate that BI 730357 has phototoxicity potential, direct exposure to 
the sun or exposure to solarium radiation is not allowed during the entire study, and use of 
sunscreens is mandatory in that time (see Section 4.2.2.2).
Women of childbearing potential have to use highly effective birth control (see Section 3.3.2). 
In addition, negative pregnancy testing will be required at the screening visit and prior to 
each administration of trial medication.

1.4.4
Overall assessment of benefit-risk ratio
BI 730357 
 has been adequately characterised in pre-clinical 
studies. The non-clinical safety package supports clinical trials in males and females with 
administration of BI 730357 for up to 39 weeks. 
Results of the SRD trial 1407.1 indicate good safety and tolerability of single oral doses of 
BI 730357 up to 800 mg (see IB [c09228382]).
The trial design is optimized to collect as much relevant information as possible on the 
pharmacokinetics of BI 730357 without exposing participating volunteers to undue risk. The 
potential for side effects has been assessed to be minimal and thus acceptable. However, there 
is always the potential for subjects receiving medication to experience adverse events (AEs), 
and rarely also serious adverse events (SAEs). Risks for subjects will be minimized and 
addressed by eligibility criteria, safety laboratory examinations, ECG and vital sign 
measurements, in-house observation periods and AE questioning.
If the investigator should have any clinical concern, the safety of subjects will be of upmost 
importance. The Investigator has the discretion to remove subjects from the trial should there 
be any safety concerns, or if the subjects’ wellbeing is at jeopardy.

All in all, the risk of the participating volunteers is judged to be low considering particularly 
the good tolerability of BI 730357 seen so far and the administration of single doses already 
investigated. With respect to the medical need for an effective and safe treatment of psoriasis, 
the benefit of this trial is assessed to outweigh the potential risks.

DESCRIPTION OF DESIGN AND TRIAL POPULATION
3.1
OVERALL TRIAL DESIGN AND PLAN
The trial consists of three parts, which will be performed in a randomised, open-label, single-
dose, two-way (Parts 1 and 2) or three-way (Part 3) crossover design in healthy male and
female subjects in order to compare the following test treatment and reference treatments:
Part 1
T1 (Test Part 1)
One 50 mg BI 730357 tablet as iCF, final batch
R1 (Reference Part 1)
One 50 mg BI 730357 tablet as TF1
Part 2
T2 (Test Part 2)
Two 100 mg BI 730357 tablets as iCF, final batch
R2 (Reference Part 2)
Two 100 mg BI 730357 tablets as TF1
Part 3
T3c (Test Part 3, coarse milled)
One 100 mg BI 730357 tablet as iCF side batch, coarse milled
T3u (Test Part 3, unmilled)
One 100 mg BI 730357 tablet as iCF side batch, unmilled
R3 (Reference Part 3)
One 100 mg BI 730357 tablet as final iCF batch, regularly milled
In Part 1 and Part 2 the iCF and TF1 will be investigated at two dose levels (at a low dose of 
50 mg and a high dose of 200 mg) due to the non-linear kinetics of BI 730357.
All treatments will be administered to the subjects as single dose in the fasting state. Within 
each trial part the subjects will be randomly allocated to the 2 treatment sequences in Part 1 
(T1/R1 or R1/T1) and Part 2 (T2/R2 or R2/T2) or to the following 3 treatment sequences in 
Part 3 (R3/T3c/T3u or T3c/T3u/R3 or T3u/R3/T3c). Each subject will participate either in Part 1
or Part 2 or Part 3, only.
There will be a washout interval of at least 10 days between the administrations of
BI 730357. 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
For relative bioavailability trials, the crossover design is preferred because of its efficiency: 
since each subject serves as his/her own control, the comparison between treatments is based 
on an intra-subject comparison, thus removing inter-subject variability from the comparison 
between treatments [R94-1529].
For this pharmacokinetic bioavailability trial, open-label treatment is acceptable, because the 
primary and secondary endpoints of this trial are pharmacokinetic endpoints derived from

study completion 
27. Lactation
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 first 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 first 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 1.2.3), 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.
If it is known that a subject becomes pregnant during the trial, administration of the trial 
medication is to be stopped immediately, and the subject is to be removed from the trial. The 
subject is to be followed until she has given birth or until the end of the 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 associated events, refer to Section 
5.2.6.2.4.

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 pregnancy, 
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
In addition to these criteria, the investigator may discontinue subjects at any time based on 
his or her clinical judgment.
Even if the trial treatment is discontinued, the subject remains in the trial and, given his/her 
agreement, will undergo the procedures for early treatment discontinuation and follow up as 
outlined in the Flow Chart and section 6.2.3.
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:
1. Failure to meet expected enrolment goals overall or at a particular trial site
2. New toxicological findings, serious adverse events, or any safety information invalidating
the earlier positive benefit-risk-assessment. More specifically, the trial will be terminated 
if more than 50% of the subjects have drug-related and clinically relevant AEs of 
moderate or severe intensity, or if at least 1 drug-related serious adverse event is reported
3. Violation of GCP or the CTP impairing the appropriate conduct of the trial
4. The sponsor decides to discontinue the further development of the investigational product

4.1.2
Selection of doses in the trial
Results from the SRD trial 1407.1 and the MRD trial 1407-0002 showed non-linear 
pharmacokinetics of BI 730357 with a less-than-dose-proportional increase in AUC and Cmax. 
Based on current guidelines [R05-1094; R10-2509] the planned bioavailability comparison of 
iCF and TF1 in Trial Parts 1 and 2 has therefore to be conducted with doses of 50 mg at the 
bottom and of 200 mg at the top end of the dose range to be tested in Phases 2 and 3. As 50
mg was seen at the top of the dose proportional range, results obtained with 50 mg in this trial 
will also cover lower doses.
For the bioavailability comparison of the three iCF batches with different particle size in 
Part 3, a dose of 100 mg in the middle of the anticipated therapeutic range was selected.
4.1.3
Method of assigning subjects to treatment groups
The randomisation list will be provided to the trial site in advance.
Subjects will be allocated to treatment sequences prior to the first administration of trial 
medication in the morning of Day 1 (Visit 2). For this purpose, numbers of the randomisation 
list will be allocated to the subjects by drawing lots. Subjects are then assigned to a treatment 
sequence according to the randomisation list. Once a subject number has been assigned, it 
cannot be reassigned to any other subject. The randomisation procedure is described in 
Section 7.6.
4.1.4
Drug assignment and administration of doses for each subject
This trial consists of two 2-way crossover parts (Trials Parts 1 and 2) and one 3-way 
crossover trial part (Trial Part 3). In Trial Parts 1 or 2, subjects will receive the 2 treatments 
in randomised order. In Trial Part 3, subjects will receive 3 treatments in randomised order. 
The treatments to be evaluated for each trial part are outlined in Tables 4.1.4: 1, 4.1.4: 2 and 
4.1.4: 3 below.

Administration of trial medication will be performed after subjects have fasted overnight; 
fasting is to start no later than 10 h before the scheduled dosing. The investigator (or 
authorised designee) will administer the trial medication as an oral dose together with about 
240 mL of water to subjects who are in a standing position. 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 restrictions with regard to diet, see Section 4.2.2.2.
Subjects will be kept under close medical surveillance until 24 h after drug administration. 
During the first 4 h after drug administration of BI 730357, subjects are not allowed to lie 
down (i.e. no declination of the upper body of more than 45 degrees from upright posture),
except for medical reasons or for recording of 12-lead ECG and vital signs measurements.
The treatments will be separated by a wash-out phase of at least 10 days between 
administrations of BI 730357.
4.1.5
Blinding and procedures for unblinding
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, because the dose of 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.

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 
Clinical Trial Manager (as provided in the list of contacts) is to be contacted immediately.
4.1.8
Drug accountability
The investigator or designee will receive the investigational drugs delivered from the sponsor
following requirements are fulfilled:

Approval of the clinical trial protocol by the IRB / ethics committee

Approval/notification of the regulatory authority,  e.g. competent authority

Availability of the curriculum vitae of the Principal Investigator

Availability of a signed and dated clinical trial protocol  
Only authorised personnel documented in the form 'Trial Staff List' may dispense medication 
to trial subjects. The trial medication must be administered in the manner specified in the
CTP.
The investigator or designee must maintain records of the product’s delivery to the trial site, 
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 medicinal product and trial subjects. The 
investigator or designee will maintain records that document adequately that the subjects 
were provided the doses specified by the CTP and reconcile all investigational medicinal 
products received from the sponsor. At the time of disposal of remaining trial medication, the 
investigator or designee must verify that no remaining supplies are in the investigator’s 
possession.
All unused medication will be disposed of locally by the trial site upon written authorisation 
of the Clinical Trial Leader. Receipt, usage and disposal of trial medication must be 
documented on the appropriate forms. Account must be given for any discrepancies.

ASSESSMENT OF SAFETY
5.2.1
Physical examination
At screening, the medical examination will include demographics, 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, 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) will be measured by a 
blood pressure monitor (Dinamap Pro 100, GE Medical Systems, Freiburg, Germany) 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.
5.2.3
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. 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.

All ECGs will be recorded for a 10 sec duration after subjects have rested for at least 5 min in 
a supine position. ECG assessment will always precede all other study procedures scheduled 
for the same time to avoid compromising ECG quality. 
All ECGs will be stored electronically on the Muse CV Cardiology System (GE Medical 
Systems, Freiburg, Germany). 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.

Assessment of adverse events
5.2.6.1
Definitions of adverse events
Adverse event
5.2.6.1.1
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.
Serious adverse event
5.2.6.1.2
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’
5.2.6.1.3
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’.
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
5.2.6.1.4
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:

Hepatic injury
A hepatic injury is defined by the following alterations of hepatic laboratory 
parameters: 
o
An elevation of AST (aspartate transaminase) and/or ALT (alanine 
transaminase) ≥3-fold ULN combined with an elevation of total bilirubin 
≥2-fold ULN measured in the same blood sample, 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.

Severe infections (grading according to Rheumatology Common Toxicity Criteria 
(RCTC) developed by OMERACT [R13-3515])

Opportunistic and mycobacterium tuberculosis infections
These include pneumocystis jirovecii, BK virus disease including polyomavirus-
associated nephropathy, cytomegalovirus, posttransplant lymphoproliferative disorder 
(Epstein-Barr virus), progressive multifocal leukoencephalopathy, bartonellosis 
(disseminated only), blastomycosis, toxoplasmosis, coccidioidomycosis,
histoplasmosis, aspergillosis (invasive only), candidiasis (invasive or pharyngeal), 
cryptococcosis, other invasive fungi (mucormycosis (zygomycosis, rhizopus, mucor, 
lichtheimia), scedosporium/pseudallescheria boydii, fusarium), legionellosis, listeria 
monocytogenes (invasive only), tuberculosis, nocardiosis, non-tuberculous 
mycobacterium, salmonellosis (invasive only), hepatitis B virus reactivation, herpes 
simplex (invasive only), herpes zoster, strongyloides (hyperinfection syndrome and 
disseminated forms only), paracoccidioides, penicillium marneffei, sporothrix 
schenckii, cryptosporidium species (chronic only), microsporidiosis, leishmaniasis 
(visceral only), trypanosoma cruzi Infection (Chagas’ disease) (disseminated only), 
campylobacteriosis (invasive only), shigellosis (invasive only), vibriosis (invasive due 
to vibrio vulnificus), hepatitis C virus progression.
Intensity (severity) of AEs
5.2.6.1.5
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
5.2.6.1.6
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
5.2.6.2
Adverse event collection and reporting
AE collection
5.2.6.2.1
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.
AE reporting to the sponsor and timelines
5.2.6.2.2
The Investigator must report SAEs, AESIs, and non-serious AEs which are relevant for the 
reported SAE or AESI, on the BI SAE form via fax immediately (within 24 hours) to the 
sponsor’s unique entry point (country specific contact details will be provided in the ISF). 
The same timeline applies if follow-up information becomes available. In specific occasions 
the Investigator could inform the sponsor upfront via telephone. This does not replace the 
requirement to complete and fax the BI SAE form. 
With receipt of any further information to these events, a follow-up SAE form has to be 
provided. For follow-up information, the same rules and timeline apply as for initial 
information.
Information required
5.2.6.2.3
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.

Pregnancy
5.2.6.2.4
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.
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.

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, and ECG parameters that might occur as a result of 
administration of trial medication. The safety assessments are standard, are accepted for 
evaluation of safety and tolerability of an orally administered drug, and are widely used in 
clinical trials. The pharmacokinetic parameters and measurements outlined in Sections 2.1.2, 
2.1.3, 2.2.2.1, and 5.3 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 are to be performed and completed within a 3h-period prior to the trial drug 
administration.
The acceptable deviation from the scheduled time for vital signs, ECG, and laboratory tests 
will be ± 30 min on Day 1, ± 45 min on Day 2, and ± 60 min from Day 3 onwards.
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.
Starting from 119 hours after BI 730357 administration (and beyond), a time window of 
± 60 min will be allowed for PK blood sampling times.
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 provide 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.
Genotyping will be performed in those volunteers whose genotypes have not been previously 
determined (for details, see Section 5.3).
6.2.2
Treatment periods
Each subject is expected to participate in 2 treatment periods (in Part 1 or Part 2) or 
3 treatment periods (Part 3). At least 10 days will separate drug administrations in the first
and second treatment period as well as in the second and third treatment period.

On Day 1 of each treatment period, study participants will be admitted to the trial site and 
kept under close medical surveillance for at least 24 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, subjects will be treated in an ambulatory fashion.
For details on time points and procedures for collection of plasma 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 5.2.6.
Subjects who discontinue treatment before the end of the planned treatment period should 
undergo the EoTrial Visit.
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 relative bioavailability of two tablet 
strengths (50 mg and 100 mg) of the intended Commercial Formulation of BI 730357 (Test, 
T) versus with the corresponding tablet strengths of trial formulation 1 (Reference, R), and to 
investigate the relative bioavailability of two iCF side batches of BI 730357 with coarse 
milled API (Testcoarse milled, Tc) and unmilled API (Testunmilled, Tu), respectively, versus final 
iCF batch of BI 730357 with regularly milled API (Reference, R) following oral 
administration on the basis of the primary and secondary pharmacokinetic endpoints, as listed 
in Section 2.1.2 and 2.1.3. The trial is designed to allow intra-subject comparisons and will be 
evaluated statistically by use of a linear model for logarithmically transformed PK endpoints. 
A further objective is to evaluate and compare further pharmacokinetic parameters between 
the treatments, see Section 2.2.1. These further pharmacokinetic parameters will be assessed 
by descriptive statistics.
The assessment of safety and 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.
7.2
NULL AND ALTERNATIVE HYPOTHESES
The relative bioavailability of BI 730357 in plasma after test versus reference treatment 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-tests 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 randomized 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 deviation 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 
 
contributes only one PK parameter value for one period 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 deviation 
(IPD) categories will be suggested in the IQRM plan, IPDs will be identified no later than in 
the Report Planning Meeting, and the IPD categories will be updated as needed.
Pharmacokinetics
The pharmacokinetic parameters listed in Section 2.1 for drug BI 730357 will be calculated
by means of non-compartmental analysis. Non-compartmental pharmacokinetic parameters 
will be calculated based on actual sampling times using a validated pharmacokinetic software 
(Phoenix® WinNonlin® 6.3). Descriptive statistics will be used to evaluate plasma 
concentration data and PK parameters. The derivation of PK parameters is described in BI 
internal SOP (001-MCS-36-472_RD-01). Further details on analysis will be described in the 
TSAP. 
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 
deviation 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 deviations 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

7.3.1
Primary endpoint analyses
Primary analyses
The primary endpoints (refer to Section 2.1.2) 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).
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 sources of variation: sequence, subjects within 
sequences, period and treatment. The effect 'subjects within sequences' will be considered as 
random, whereas the other effects will be considered as fixed. The model is described by the 
following equation, where p=2 for Parts 1 and 2 of the trial and p=3 for Part 3 of the trial:
yijkm = + i + sim + j + k + eijkm, where
yijkm = logarithm of response measured on subject m in sequence i receiving treatment  
k in period j,
= the overall mean,
i = the ith sequence effect, i = 1, …, p
sim = the effect associated with the mth subject in the ith sequence,
m = 1, 2, ..., ni
j = the jth period effect, j = 1,, …, p
k = the kth treatment effect, k = 1,, …, p
eijkm = the random error associated with the mth subject in sequence i who received
treatment k in period j.
where s ~ N(0, σ
) i.i.d., e ~ N(0, σ
 ) i.i.d. and sim, eijkm are independent random 
variables.
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.

Further exploratory analyses
The same statistical model as stated above will be repeated for the primary endpoints but with 
all sources of variation (‘sequence’, ‘subjects within sequences’, ‘period’, ‘treatment’) 
considered as fixed effects.
In addition to the model based approach all parameters will be calculated and analysed 
descriptively.
7.3.2
Secondary endpoint analyses
The secondary endpoints (refer to Section 2.1.3) will be calculated according to the BI SOP 
‘Standards and processes for analyses performed within Clinical Pharmacokinetics/ 
Pharmacodynamics’ (001-MCS-36-472) and will be assessed statistically using the same 
methods as described for the primary endpoints.
7.3.4
Safety analyses
Safety will be analysed based on the assessments described in Section 2.2.2.2. All treated 
subjects (TS, refer to Section 7.3) 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 randomised 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 
REP (see Section 1.2.3) will be assigned to the treatment period. Events occurring after the 
REP but prior to next intake or end of trial termination date will be assigned to ’follow-up’. 
In case of two or more treatments, the follow-up will be summarized according to the 
previous treatment. 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.
Additionally, further treatment intervals (analysing treatments) may be defined in the TSAP 
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 follow-up 
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 5.2.6.1), 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. 
Relevant ECG findings will be reported as AEs.

RANDOMISATION
Subjects will be randomised to one of the 2 treatment sequences in Part 1 (T1/R1 or R1/T1) or 
Part 2 (T2/R2 or R2/T2) in a 1:1 ratio. For Trial Part 3, subjects will be randomised to one of 
3 treatment sequences (R3/T3c/T3u or T3c/T3u/R3 or T3u/R3/T3c) in a 1:1:1 ratio. The block size 
will be documented in the CTR.
The sponsor will arrange for the randomisation as well as packaging and labelling of trial 
medication. The randomisation list will be generated using a validated system that uses a 
pseudo-random number generator and a supplied seed number so that the resulting allocation 
is both reproducible and non-predictable.
The randomisation list will contain additional blocks to allow for subject replacement (refer 
to Section 3.3.5).

DETERMINATION OF SAMPLE SIZE
It is planned to enter 14 subjects in Part 1, 14 subjects in Part 2 (accounting for up to 2 non 
PK evaluable subjects in each part), and 15 subjects in Part 3 of this trial (accounting for up 
to 3 non PK evaluable subjects), because these sample sizes are considered sufficient to 
achieve the aims of this exploratory trial parts. 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 intra-individual coefficient of variation (gCV) is estimated from total gCV from 
pharmacokinetic data of the SRD part of a previous trial (Study 1407.1) using the result of 
50 mg dose, 100 mg and 200 mg doses. Table 7.7:1 below presents, for each dose, the 
observed total gCV in this previous trial, for each primary endpoint, as well as the roughly 
estimated intra-individual gCV.

Parts 1 and 2
Assuming a gCV of 22% for BI 730357 and given a sample size of 12 subjects with 
evaluable data for primary analysis, the precision of the two-sided 90% confidence interval of 
the bioavailability ratio will be approximately 1.243, for a greater gCV of 26%, the precision 
would still be approximately 1.292. For a lower gCV (17%), the precision would be 
approximately 1.184. Table 7.7: 2 provides an overview of the achievable precision for 
estimating the ratio of geometric means (test/reference) applicable to Parts 1 and 2 of the trial 
(two-way crossover). For illustrative purposes, the expected 90% confidence intervals with 
95% tolerance probability are displayed for different values of the ratios T/R of geometric 
means.

the subjects, and are stored in the ISF.
8.1
TRIAL APPROVAL, SUBJECT INFORMATION, INFORMED CONSENT
This trial will be initiated only after all required legal documentation has been reviewed and 
approved by the respective Institutional Review Board (IRB / Independent Ethics Committee 
(IEC and competent authority (CA) according to national and international regulations. The 
same applies for the implementation of changes introduced by amendments.
Prior to a subject’s participation in the trial, written informed consent must be obtained from 
each subject (or the subject’s legally accepted representative) according to ICH-GCP and to 
the regulatory and legal requirements of the participating country. Each signature must be 
personally dated by each signatory and the informed consent and any additional subject-
information form retained by the investigator as part of the trial records. A signed copy of the 
informed consent and any additional subject information must be given to each subject or the 
subject’s legally accepted representative.
The subject must be given sufficient time to consider participation in the trial. The 
investigator or delegate obtains written consent of the subject’s own free will with the 
informed consent form after confirming that the subject understands the contents. The 
investigator or 
 delegate must sign (or place a seal on) and date the informed consent form. 
If a trial collaborator has given a supplementary explanation, the trial collaborator also signs 
(or places a seal on) and dates the informed consent.

8.2
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.
ClinBaseTM
In the Human Pharmacology Centre (HPC) – Boehringer Ingelheim's Phase I unit – the 
validated ClinBaseTM system is used for processing information and controlling data 
collected in clinical studies. In addition to its function as a procedure control system, 
ClinBaseTM serves as data base. Instead of being entered into CRFs, selected data are directly 
entered into the system.
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

Medical history (including trial indication and concomitant diseases, if applicable)

Medication history

AEs and outcome events (onset date [mandatory], and end date [if available])

SAEs (onset date [mandatory], and end date [if available])

Concomitant therapy (start date, changes)

Originals or copies of laboratory results and other imaging or testing results, with 
proper documented medical evaluation (in validated electronic format, if available)

ECG results (original or copies of printouts)

Completion of subject’s participation in the trial (end date; in case of premature 
discontinuation, document the reason for it, if known)

Prior to allocation of a subject to a treatment into a clinical trial, there must be 
documented evidence in the source data (e.g. medical records) that the trial participant 
meets all inclusion criteria and does not meet any exclusion criteria. The absence of
records (either medical records, verbal documented feedback of the subject or testing 
conducted specific for a protocol) to support inclusion/exclusion criteria does not 
make the subject eligible for the clinical trial.
Data directly entered into ClinBaseTM (that is, without prior written or electronic record) are 
considered to be source data. The place where data are entered first will be defined in a trial 
specific Source Data Agreement. The data in ClinBaseTM are available for inspection at any 
time.
8.3.2
Direct access to source data and documents
The investigator /institution will allow site trial-related monitoring, audits, IRB/IEC review 
and regulatory inspections. Direct access must be provided to the CRF and all source 
documents/data, including progress notes, copies of laboratory and medical test results, which 
must be available at all times for review by the Clinical Research Associate, auditor and 
regulatory inspector (e.g. FDA). They may review all CRFs and informed consents. The 
accuracy of the data will be verified by direct comparison with the source documents 
described in section 8.3.1. The sponsor will also monitor compliance with the protocol and 
GCP.
8.3.3
Storage period of records
Trial site:
The trial site(s) must retain the source and essential documents (including ISF) according to 
the local requirements valid at the time of the end of the trial.
