1. 
INTRODUCTION 
This statistical analysis plan (SAP) defines the statistical analysis methods and data preparations 
to be used in the analysis and presentation of data for Galapagos protocol number 
GLPG1690-CL-206 entitled ‘A multicenter, open-label extension study to evaluate the long-
term safety, tolerability and efficacy of orally administered GLPG1690 in subjects with 
systemic sclerosis’. 
A decision was taken to halt the GLPG1690-CL-206 clinical study with the investigational 
autotaxin inhibitor ziritaxestat (sponsor product code GLPG1690) in subjects with systemic 
sclerosis. The decision is based on the recommendations of the Independent Data Monitoring 
Committee of the ISABELA Phase 3 clinical studies (study numbers GLPG1690-CL-303 and 
GLPG1690-CL-304) which, following a regular review of unblinded data on February 9, 
concluded that ziritaxestat’s benefit-risk profile no longer supported continuing these studies. 
In view of the above, no market authorisation application will be submitted for ziritaxtestat for 
the treatment of systemic sclerosis. Therefore, it was decided to limit the analyses to the primary 
safety endpoints and any analyses important to better understand the reason for the results seen, 
or for scientific knowledge for future compounds. 
The results will be presented in an abbreviated clinical study report (CSR). 
All descriptions as documented in the SAP were kept for reference, but endpoints and analyses 
deemed not applicable for the abbreviated CSR are in Italic font and will not be included for 
the final analysis. A list of analyses that will not be performed can be found in section Error! R
eference source not found.. 
The statistical analysis will process and present the results following the International Council 
for Harmonization (ICH) standards, particularly the ICH-E3, ICH-E6 and ICH-E9 guidelines, 
and 
 Global Biostatistics and Programming & Galapagos Standard Operating Procedures 
(SOPs). This SAP is created based on the latest Clinical Study Protocol (CSP) as referred in 
section 2.4. Technical details on derivations and mock Tables, Listings and Figures (TLFs) will 
be presented in a separate document. 
Data from both the GLPG1690-CL-204 (CL-204) and GLPG1690-CL-206 (CL-206) protocols 
will be stored in CL-206 SDTM and ADaM datasets, the CSR prepared for CL-206 study will 
report cumulative data across both protocols.

SAMPLE SIZE JUSTIFICATION 
Thirty subjects (20 on 600 mg oral q.d. ziritaxestat and 10 on placebo) are planned to be 
randomized in the preceding CL-204 study. All subjects who completed the 24-week double-
blind treatment in this preceding study, signed the informed consent form (ICF) of the OLE 
study, and are eligible for the OLE will be included. Thus, up to 30 subjects may roll over and 
be enrolled in this OLE study. No formal sample size calculation was performed.

2.7. 
RANDOMIZATION AND BLINDING 
Randomization 
This is an open-label study with one dose level of IP; no randomization will be performed.  
At the Rollover visit (visit 1), subjects confirmed to be eligible for this OLE study will be 
enrolled. Subjects will retain the subject identification number assigned in CL-204. 
Blinding and Unblinding 
This is an open-label clinical study and treatment in this extension study will not be blinded. 
3. 
GENERAL METHODOLOGY 
Subjects will be analyzed as per their CL-204 study treatment assignment; therefore, this will 
be meant by the ‘treatment group’ reference. 
3.1. 
ANALYSIS SETS 
The analysis sets used in the statistical analyses are detailed in the following subsections. The 
analysis set will always be indicated in a subtitle in the TLF. 
3.1.1. Full Analysis Set 
The full analysis set (FAS) is defined as all randomized subjects who had received at least 1 
intake of IP in the preceding CL-204 study.   
3.1.2. OLE All Enrolled Subjects 
All subjects who were found eligible to participate in the OLE clinical study. 
3.1.3. OLE Full Analysis Set 
The OLE full analysis set (OLE FAS) is defined as all subjects who had at least one intake of 
IP in the OLE study. 
3.2. 
RANDOMIZED VERSUS ACTUAL TREATMENT GROUP 
This is an open-label study with one dose level of IP; no randomization will be performed. 
Subjects will be analyzed according to the treatment arm to which they were randomized in the 
preceding CL-204 study. 
3.3. 
ANALYSIS PERIODS AND ANALYSIS TIME POINTS 
3.3.1. Relative Day 
The timing of an assessment or an event relative to a reference date will be calculated as follows: 
Relative day ሺDYሻ

ൌconcerned date െreference date ൅1 day,  when concerned date  ൒ reference date  
ൌconcerned date െreference date, when the concerned date ൏ reference date  
- 
The reference date is the date of the first CL-204 IP intake, unless specified otherwise. 
The first OLE IP intake can also be used as reference date, if specifically stated. 
- 
The concerned date could be the measurement date of the assessment, or the start or end 
date of the event. 
- 
Date implies a complete date. If the date is (partially) missing, the relative day will be 
missing.  
Exception: if the end date of an event is fully missing at database lock (in case of an interim 
analysis) or at the subject’s study termination, the event will be considered as ongoing. The end 
date will be imputed by the database cutoff date or the date of last visit for cases where subject 
terminated study. 
3.3.2. Duration 
The duration of an assessment or an event will be calculated as follows: 
Duration ሺdaysሻൌend date െstart date ൅1 day 
Date implies a complete date. If the date is (partially) missing, the duration will be missing.  
Exception: If the end date of an event is fully missing at database lock (in case of an interim 
analysis) or at the subject’s study termination, the event will be considered as ongoing. The end 
date will be imputed by the database cutoff date or the date of last visit for cases where subject 
terminated study. In listing, the duration will be printed as “> X days”. 
3.3.3. Analysis Periods  
All event-type data (e.g., AEs) and assessments will be allocated to analysis periods according 
to Table 1. Analysis periods will be defined based on cumulative data collected during both 
CL-204 and CL-206 studies.

3.3.4. Analysis Windows 
All CL-204 study assessments prior to the first OLE IP dose day including data collected on 
unscheduled visits, will be allocated to analysis visits (time windows) based on the relative day 
of the assessment using the first CL-204 IP dose date as reference date (see section 3.3.1) and 
according to the algorithm in Table 2. All CL-206 study assessments from the day of the first 
OLE IP dose onwards including data collected on unscheduled visits will be allocated to 
analysis visits where the reference date will be regarded as the first OLE IP dose date. All non-
follow-up post-baseline visits will fall within the treatment period as defined in Table 1. TLFs 
will present the analysis visits when analysis is derived.

multiple values on the same day and no time indicating which one is last, the average of the 
values will be calculated. 
3.4. 
HANDLING OF DATA 
3.4.1. Handling of Missing Data 
3.4.1.1. 
Handling of Missing Date Time Data 
Generally, no imputations will be done in case of missing date (time) fields, nor for the missing 
parts of partially known date (time) fields apart from partially missing initial diagnosis dates. 
When the date of initial diagnosis is partially missing, the following rules will be used in order 
to determine the duration of disease: 
• 
If the day of initial diagnosis is missing, then 01 will be assigned to the missing 
fields. 
• 
If the month of initial diagnosis is missing, then January will be assigned to the 
missing fields. 
• 
If date of initial diagnosis is completely missing, no imputation will be done. 
Assessments with completely missing date (time) will be omitted from the analysis.  
Event-type data (e.g. adverse events, concomitant medications) with missing date (time) will 
be allocated to analysis periods using a worst-case approach as explained in the respective 
sections. If the end date of an event is fully missing at database lock (in case of an interim 
analysis) or at the subject’s study termination, the event will be considered as ongoing. 
3.4.1.2. 
 Handling of Missing Result Data 
No imputation will be done of missing results unless specified otherwise in corresponding 
sections (i.e. observed cases (OC) analysis). 
3.4.2. Handling of Values Below or Above a Threshold 
Values below (above) the quantification limit will be imputed by the value one unit smaller 
(larger) than the quantification limit itself. In listings, the original value will be presented. 
Example: if the database contains the value “<0.04”, then for the descriptive statistics the value 
“0.03” will be used. The value “>1000” will be imputed by “1001”. 
3.4.3. Handling of Outliers 
There will be no outlier detection, all measured values will be included in the analyses.

PRESENTATION OF RESULTS 
3.5.1. Presentation of Treatment groups 
A grand total “Total” will be added to summarize all subjects over all CL-204 treatment groups 
in all tables and figures. 
3.5.2. Calculation of Descriptive Statistics 
For continuous parameters, descriptive statistics will be presented when n≥2. When n=1, only 
the summary statistics for n and mean will be displayed, other summary statistics will be left 
blank.  
Descriptive statistics will include:  
- 
the number of non-missing data points (n)  
- 
the arithmetic mean 
- 
the standard error (SE) and standard deviation (SD) 
- 
the median, minimum and maximum 
- 
95% confidence interval (CI) of the mean (if indicated in the relevant section). 
3.5.3. Calculation of Percentages 
Frequencies and percentages will be generated for categorical parameters. 
For event-type data (e.g. Adverse Events), the denominator will be all subjects in the analysis 
set and analysis visit/period. For other data (e.g. worst-case analysis of assessments), the 
denominator will be all subjects with post-baseline data for the parameter, in the analysis set 
and analysis visit/period. 
3.5.4. Additional Considerations 
All data collected except for assessment that were not done will be listed in data listings.

completed Follow-up phase and subjects who discontinued the CL-206 study and the 
reasons for discontinuation. 
5.2.3.  Protocol Deviations and Eligibility 
Major protocol deviations are determined and recorded while the study is ongoing, and the list 
is finalized prior to database lock. For more details, please refer to the Study Deviations Rules 
document. 
The number (percent) of subjects with major protocol deviations will be tabulated, overall and 
per class of deviation, by treatment group and overall.  
All available information concerning major protocol deviations, deviations on eligibility criteria 
and subjects not treated will be listed. Major and minor protocol deviations related to the 
COVID-19 pandemic will be displayed separately. 
5.2.4. Inclusion and Exclusion Criteria 
All CL-206 study inclusion and exclusion criteria that subjects did not fulfil will be listed in 
detail for the FAS. 
5.2.5. Medical History and Concomitant Diseases 
Medical history will be coded using the version of the medical dictionary for regulatory 
activities (MedDRA) used in the preceding CL-204 study as per the data validation manual 
(DVM). The number and percentage of subjects with any medical history will be summarized 
overall and for each predefined system organ class (SOC) and preferred term (PT). Frequency 
tabulations per SOC and PT will be provided for the medical history findings: (i.e., any event 
with a stop date prior to first CL-204 IP intake) as well as for the concomitant diseases (i.e., 
ongoing conditions or conditions with a stop date on or after first CL-204 IP intake). 
5.2.6. Prior and Concomitant Medications 
A prior medication is defined as any medication that is taken prior to the first dose of CL-204 
IP. A concomitant medication is defined as any medication that has a stop date that is on or 
after the date of first dose of CL-204 IP or is ongoing. Medications that started prior to the 
first dose of CL-204 IP and have stop date on or after the first dose of CL-204 IP or is 
ongoing are defined as both prior and concomitant medications. 
5.2.6.1. 
Coding of Reported Terms 
All prior and concomitant therapy terms will be coded in the database using the version of 
World Health Organization Drug Dictionary (WHO-DD) used in the preceding CL-204 study. 
5.2.6.2. 
Classification of Medications 
All prior and concomitant medication records will be categorized as follows, considering their 
date and flags indicating the relative timing versus study (IP) start or end (before, after, 
ongoing…):

- 
Prior only: when the record ended before first CL-204 IP administration date. 
- 
Concomitant only: when the record started on or after the first CL-204 IP administration 
date. 
- 
Prior and concomitant: when the record started before the date of first CL-204 IP 
administration, and ended on or after this point, or continued, or if end date is missing. 
When the start or end date of the prior and concomitant medication records are incomplete (and 
no flags indicating relative timing are available), the date of first CL-204 IMP administration 
will be considered to the same level of information provided by these incomplete dates to 
categorize the timing of these records. This means that a record only having month and year 
will be categorized comparing only to the month and year of the date of first CL-204 IP 
administration. Worst case scenario will be used to categorize concomitant medications: if the 
same level of information provided by incomplete concomitant medication start date is identical 
to first CL-204 IP administration, then the medication will be considered as both prior and 
concomitant, given end date is not prior to first CL-204 IP administration. If the same level of 
information provided by incomplete concomitant medication end date is identical to first CL-
204 IP administration, then the medication will be considered as both prior and concomitant, 
given start date is not after to first CL-204 IP administration. 
5.2.6.3. 
Calculation of Relative Days 
For both the start and the end dates of the concomitant medication records, their day relative to 
the day of first CL-204 IP administration will be calculated as described in section 3.3.1. In 
addition, start and end dates relative to the day of first OLE IP administration will be presented. 
5.2.6.4. 
Presentation of Results 
A frequency tabulation of the anatomical therapeutic chemical (ATC) classes Level 4 by 
therapeutic subgroup (ATC Level 2) and anatomical main group (ATC Level 1) of the prior 
medications (defined as ‘prior only’ and ‘prior and concomitant’) will be provided as well as 
of the concomitant medications (defined as ‘concomitant only’ and ‘prior and concomitant’). A 
separate table will be produced for concomitant medications taken during the CL-206 study. 
All medications will be listed in detail. 
5.2.7. Prior and Concomitant Non-Drug Therapies 
5.2.7.1. 
Coding of Reported Terms 
All non-drug therapies used within 12 weeks prior to and during the screening period will be 
collected on the electronic case report form (eCRF). All non-drug therapies will be coded 
according to the version of MedDRA Dictionary used in the preceding CL-204 study. 
A prior non-drug therapy is defined as any non-drug therapy that is taken prior to the first dose 
of CL-204 IP. A concomitant non-drug therapy is defined as any non-drug therapy that has a 
stop date that is on or after the date of first dose of CL-204 IP or is ongoing.

relative to the day of first CL-204 IP administration will be calculated as described in section 
3.3.1. 
5.2.7.4. 
Presentation of Results 
A frequency tabulation of the SOC and PT term of non-drug therapies of the prior therapies 
(defined as ‘prior only’ and ‘prior and concomitant’) will be provided. Similarly, a separate

Coding information (SOC, PT, high level group term, high level term, low level term and 
verbatim) based on all the collected AE data will be presented in a listing.   
5.4.1.3. 
Allocation of Adverse Events to Analysis Periods 
All AEs records will be placed into analysis periods considering their start date, aiming to report 
the incidence of these events only in the analysis period during which they started. 
The general rule for allocation of AEs to analysis periods follows: 
Analysis period start date ≤ AE start date ≤ analysis period end date  
If the start date of an AE is missing or incomplete to a level preventing a clear allocation of the 
AE to one single analysis period and no flag indicating timing relative to study medication is 
available, a worst-case consideration (see below) will be done aiming to allocate the AE to one 
single analysis period, if possible. When a worst-case consideration is needed, the end date of 
the AE, if and as available, should also be considered; if such AEs clearly end on a given point, 
this will exclude the possibility to allocate the AE to an analysis period after that point. 
- 
An AE which according to the available information of its start date could belong to the 
screening as well as to the treatment period will only be placed in the treatment period. 
- 
An AE which according to the available information of its start date could belong to 
treatment period as well as to follow-up period will only be placed in the treatment 
period. 
- 
An AE with a missing start date will be allocated to treatment period. 
- 
If an AE can be allocated to both double-blind (i.e. CL-204 study) and open-label (i.e. 
CL-206 study) treatment sub-periods, then the event will be reported for CL-204 
double-blind treatment sub-period during CL-206 study analyses.  
5.4.1.4. 
Treatment Relatedness 
Following ICH-E3 (ICH), the originally reported relatedness to IP of an AE will be 
dichotomized as follows: 
- 
Not IP related: all non-missing weaker levels of relatedness than ‘possibly IP related’ 
(unrelated, unlikely).  
- 
IP related: ‘possibly IP related’ and all stronger levels of relatedness (probable, certain) 
- this class also includes any missing IP relatedness, as a worst-case consideration. 
Only this dichotomized relatedness will be used in tables. Relatedness as originally reported 
will only be listed.  
5.4.1.5. 
Presentation of Adverse Events and of Event Episodes 
All AEs tables will only show TEAEs and will show counts of the number of subjects with 
TEAEs. The number of event episodes will be shown only in tables where explicitly mentioned.

Tables will be produced for cumulative data collected during both CL-204 and CL-206 studies. 
Separate tables will be produced for CL-206 study data. 
AEs starting before first CL-204 IP administration or later than 30 days after the last OLE dose 
of IP will only be listed.  
AEs leading to death will be presented in a separate listing.  
5.4.1.6. 
Worst-Case Selections 
When cross-tabulating AE preferred terms versus an AE attribute (like severity), only the worst-
case within each same preferred term, same subject and same analysis period will be considered, 
i.e., when a same subject has more than once the same AE preferred term reported in the same 
treatment group, the subject will be counted only once and will be shown under the worst 
outcome (like the worst severity for that AE in the concerned treatment period). 
Worst-case will be defined based on cumulative data collected during both CL-204 and CL-206 
studies. Additionally, worst-case will be defined based on CL-206 study data. 
5.4.1.7. 
Calculation of Relative Days and Duration 
For each AE record, its start day in study (the day of the AE start date relative to the date of 
first IP administration), its start day in the analysis period, and its duration (in days) will be 
calculated and shown only in listings.  
See sections 3.3.1 and 3.3.2 for the calculation of relative days and duration respectively. 
5.4.1.8. 
Presentation of Results 
A summary table will be provided, showing then number (percentage) of subjects with: 
- 
at least one TEAE, 
- 
at least one IP-related TEAE,  
- 
at least one serious TEAE,  
- 
at least one TEAE leading to death,  
- 
any TEAEs by worst severity (mild, moderate, severe, life threatening, and death),  
- 
at least one TEAE leading to IP discontinuation, 
- 
at least one TEAE leading to IP interruption. 
Frequency tabulations, by SOC and PT, of the number (percent) of subjects with a TEAE will 
be presented by prior treatment group as assigned in the preceding study. Similar tables will be 
provided for the following groups: 
- 
Severity (‘Grade 1 - Mild’, ‘Grade 2 - Moderate’, ‘Grade 3 - Severe’, ‘Grade 4 - Life 
Threatening’, and ‘Grade 5 - Death’)

(Specific unit into which the defined grades apply). 
Baseline value is defined as abnormal if the value is not within the normal range. For directional toxicity of high an abnormal baseline 
will be a baseline value which is higher than the upper limit of the reference range. For directional toxicity of low, an abnormal baseline 
will be a baseline value which is lower than the lower limit of the reference range. 
x LLN / x ULN = times the lower / times the upper limit of the normal range. 
Below / above = differentiate grade definitions in the low / high sense for a same parameter.  
 
The following parameters will be analyzed and categorized based on pre-defined criterion 
without using the above defined grading system: 
- Prothrombin time: >ULN-1.5 x ULN; >1.5 x ULN - 2.5 x ULN; >2.5 x ULN 
- Glucose [fasting] (mmol/L): >7.2 
- High density lipoprotein (mmol/L): <1.554 
- Low density lipoprotein (mmol/L): >4.144 
The analysis of these parameters will be performed in the same way as the analysis of the 
parameters with standard toxicity grade.

Definition of Non-Graded Abnormalities 
Non-graded abnormalities will be determined only for the parameters having no definitions of 
toxicity grades (see section 5.4.3.3). 
For laboratory tests provided by the laboratory, the position of the actual analysis values versus 
their normal ranges will be determined directly by using the position indicator provided in the 
database as reported, expressing the classes for these analysis values as low (L), normal (N) or 
high (H). L, N and H are further referred to as non-graded abnormalities. 
5.4.3.5. 
Urinalysis Tests with Categorical Results  
Results of urinalysis with qualitative results will be tabulated by time point. No toxicity grading 
or non-graded abnormalities will be derived.  
5.4.3.6. 
Treatment Emergent Principle  
Toxicity Grades 
A post-baseline toxicity grade 1, 2, 3 or 4 is defined as treatment-emergent when higher than 
the toxicity grade of the baseline result. If the baseline result is missing, a post-baseline toxicity 
grade 1, 2, 3 or 4 will always be considered as treatment-emergent. 
For prothrombin time parameter a post-baseline value meeting the defined abnormality criteria 
is regarded as treatment-emergent if the post-baseline criteria meet a higher degree of 
abnormality than the baseline value (e.g. post-baseline value meeting >1.5-2.5 x ULN category 
while baseline meeting >ULN-1.5 x ULN category) or the baseline value is missing or does not 
meet any abnormality criteria. For glucose [fasting], high density lipoprotein and low-density 
lipoprotein a post-baseline abnormal category will be regarded as treatment emergent, if the 
baseline value is missing or does not meet the defined abnormality criteria. 
Non-graded Abnormalities 
A post-baseline non-graded abnormality class L or H is defined as treatment-emergent when it 
differs from the abnormality class of the baseline result. If the baseline result is missing, a post-
baseline abnormality L or H will always be considered as treatment-emergent. 
5.4.3.7. 
Worst-Case 
Toxicity Grading 
The worst-case post-baseline toxicity grade 0, 1, 2, 3 or 4 will be determined per subject, per 
parameter (and sense, if below and above) during the on-treatment analysis period, using all 
non-missing post-baseline records within that period (including unscheduled and follow-up 
visits). 
The worst-case toxicity grade is the highest toxicity grade scored for the parameter (in each 
sense, if below and above).  
Worst-case will be defined based on cumulative data collected during both CL-204 and CL-206 
studies. Additionally, worst-case will be defined based on CL-206 study data.

Continuous parameters will be summarized by means of descriptive statistics (including 95% 
CI of the mean change from t-test) by parameter, treatment group and analysis visit. Actual 
values and changes from baseline will be tabulated separately.  
Figures of the mean (± SE) actual values over time and of the mean (± SE) change from baseline 
will be prepared for all parameters.  
All laboratory abnormalities on or after the first dose of IP administration in the preceding CL-
204 study up to the last contact after the last dose of OLE IP will be included. 
Abnormalities of the actual values will be presented as shift tables of the worst-case abnormality 
versus the baseline abnormality/toxicity grade. The table will be created per parameter and 
treatment group for the on-treatment analysis period. The results of non-graded abnormalities 
and toxicities grades will be shown separately. 
A frequency table of the number (percentage) of subjects with treatment-emergent worst-case 
abnormalities per parameter and treatment group for the on-treatment analysis period will be 
presented. The results of non-graded abnormalities and toxicities grades will be shown 
separately. 
Urinalysis tests for which no normal range is available will be tabulated separately as 
categorical data. 
Clinical laboratory values will also be listed including normal ranges and indicating if value is 
out of range. A separate listing will also be created to include all abnormal laboratory values. 
Analyses will be performed for cumulative data collected during both CL-204 and CL-206 
studies. Additionally, analyses will be performed for CL-206 study data. 
5.4.4. Electrocardiogram 
5.4.4.1. 
Available Data 
All subjects will have a standard 12-lead electrocardiogram (ECG) performed at the time points 
specified in the Schedule of Activities (see Appendix 1). The following ECG parameters will 
be analyzed: heart rate (bpm), PR interval, QRS interval, uncorrected QT interval (ms), 
morphology, QT interval corrected for the heart rate using Fridericia’s formula (QTcF) (ms). 
5.4.4.2. 
Derivation Rules 
Derived Parameters 
The ECG parameters will be provided in the clinical database, no imputation will be done. 
Handling of ECGs Measured in Triplicate 
If ECG is collected in triplicates (or duplicates), the following approach will be taken.

The mean of the triplicate (or duplicate) ECG values will be calculated for each individual 
ECG parameter, without rounding the result. These calculated means will constitute the 
analysis values; any derivation (e.g. change from baseline, assignment of abnormalities) and 
statistic will be based on the mean value of the triplicates (or duplicates). 
When a single ECG is performed, the actual results of the single ECG will be summarized. 
The values of the individual triplicate (or duplicate) assessments will be listed, i.e. will not be 
summarized or graphically presented. 
5.4.4.3. 
Abnormalities 
The actual analysis values and changes from baseline of the QT and QTcF parameters will be 
categorized into the abnormality classes as defined in ICH E14:

* Indicate which QT(c) parameter is analyzed in the label 
For electrocardiogram (ECG), where triplicates (or duplicates) results are measured, the 
baseline is defined as the mean of the last recorded triplicates (or duplicates) results before 
first IP administration. If no triplicate (or duplicate) results are available before the first dose, 
the last value before first study drug administration will be used. 
5.4.4.4. 
Worst-Case Abnormality 
For the overall interpretation the worst-case post-baseline will be determined per subject, per 
parameter, and for on-treatment analysis period, using all non-missing post-baseline records 
(including unscheduled and follow-up visits) as follow: 
- 
Normal: if all the post-baseline results are normal 
- 
Abnormal: if at least one post-baseline result is abnormal. 
Worst-case will be defined based on cumulative data collected during both CL-204 and CL-206 
studies. Additionally, worst-case will be defined based on CL-206 study data.

5.4.4.5. 
Treatment Emergent Abnormalities 
Actual value: An abnormal post-baseline abnormality is defined as treatment-emergent when 
the abnormality is worse compared to the abnormality at baseline. If the baseline result is 
missing, a post-baseline result outside of the normal range will always be considered as 
treatment-emergent. 
An abnormal category for change from baseline is always treatment-emergent. 
Additional analyses will be performed for CL-206 study data, where baseline will be regarded 
the last non-missing value before first OLE IP administration. 
5.4.4.6. 
Presentation of Results 
No formal inferential statistics (p-values) will be presented. 
Continuous parameters will be summarized by means of descriptive statistics (including 95% 
CI of the mean change from t-test) by parameter, treatment group and analysis visit. Actual 
values and changes from baseline will be tabulated separately and tables will be produced 
including all time points in the preceding CL-204 and CL-206 studies. Separate tables will be 
produced for CL-206 study data. 
All ECG abnormalities on or after the first dose of IP administration in the preceding CL-204 
study up to the last contact after the last dose of OLE IP will be listed. 
Abnormalities of the actual values will be presented as shift tables of the worst-case abnormality 
versus the baseline abnormality. The table will be created per parameter and treatment group 
for the on-treatment analysis period. Tables will be produced for cumulative data collected 
during both CL-204 and CL-206 studies. Separate tables will be produced for CL-206 study 
data. 
A frequency table of the number (percentage) of subjects with treatment-emergent worst-case 
abnormalities per parameter and treatment group for the on-treatment analysis period will be 
presented. Overall interpretation as assessed by the investigator will also be summarized and 
listed. 
5.4.5. Vital Signs 
5.4.5.1. 
Available Data 
The following vital signs parameters will be analyzed: Systolic Blood Pressure (SBP) (mmHg), 
Diastolic Blood Pressure (DBP) (mmHg), heart rate (bpm), respiratory rate (breaths/minute), 
and body temperature (ᵒC). If blood pressure is collected supine, semi-recumbent, sitting, or 
standing, then results are presented by assessment position. If there are more values available 
for a subject taken by different positions for a visit, then selection rules for the analyses will be 
applied as described in Section 3.3.4. No adjustment to the temperature will be made to account 
for the possible different method of collection.

5.4.5.3. 
Treatment Emergent Principle 
A post-baseline abnormality class L or H is defined as treatment-emergent when it differs from 
the abnormality class at baseline. If the baseline result is missing, a post-baseline abnormality 
L or H will always be considered as treatment-emergent. 
Baseline is defined as the last non-missing value before first IP administration in the preceding 
CL-204 study. Additional analyses will be performed for CL-206 study data, where baseline 
will be regarded the last non-missing value before first OLE IP administration.  
5.4.5.4. 
Worst-Case Abnormality 
The following worst-case post-baseline abnormalities low, below the lower limit of the normal 
range (L), normal, with the limits of the normal range (N) or high, above the upper limit of the 
normal range (H) will be determined per subject, per parameter and for the on-treatment 
analysis period, using all non-missing post-baseline records (including unscheduled and follow-
up visits):   
- 
L = low: at least one post-baseline result is classified as L. 
- 
N = normal: all post-baseline results are classified as N.  
- 
H = high: at least one post-baseline result is classified as H. 
If, for a subject, both L and H are reported, the subject will be counted twice in the table: once 
with a worst-case L and once with a worst-case H. 
Worst-case will be defined based on cumulative data collected during both CL-204 and CL-206 
studies. Additionally, worst-case will be defined based on CL-206 study data. 
5.4.5.5. 
Presentation of Results 
No formal inferential statistics (p-values) will be derived.

Continuous parameters will be summarized by means of descriptive statistics (including 95% 
CI of the mean change from a t-test) for all vital sign parameters and analysis visits, by treatment 
group and overall. Actual values and changes from baseline will be tabulated separately and 
tables will be produced including all time points in the preceding CL-204 and CL-206 studies. 
Separate tables will be produced for CL-206 study data.  
All abnormalities on or after the first dose of IP administration in the preceding CL-204 study 
up to the last contact after the last dose of OLE IP will be included. 
Abnormalities of the actual values will be presented as shift tables of the worst-case abnormality 
versus the baseline abnormality. The table will be created per parameter (and position if 
applicable), and treatment group for the on-treatment analysis period. Tables will be produced 
for cumulative data collected during both CL-204 and CL-206 studies. Separate tables will be 
produced for CL-206 study data. 
Frequency table of the number (percentage) of subjects with treatment-emergent worst-case 
abnormalities per parameter and treatment group for the on-treatment analysis period will be

206 studies. Separate tables will be produced for CL-206 study data. 
Mean (± SE) plots over time for both treatment groups, with heart rate, respiratory rate, body 
temperature, and blood pressure by position on a new page, will be displayed. Separate plots 
will be produced for mean actual values and changes from baseline. 
5.4.6. Physical Examinations 
Abnormal physical examination results (including gynaecological exam results for female 
subjects) will be presented in a listing.  
5.4.7. Hospitalization 
All information recorded in the eCRF page “Hospitalization Details” will be listed.
