PROTOCOL SYNOPSIS 
Study Title: 
A phase II, randomised, double blind, placebo-controlled study of the 
pharmacokinetics, pharmacodynamic effects, and safety, of oral FT011 in 
participants with diffuse systemic sclerosis 
Study Period: 
2021 - 2022 
Objectives: 
Primary objective: 
• 
To assess the pharmacokinetics (PK) of oral FT011 in participants with diffuse 
systemic sclerosis (SSc). 
Secondary objectives: 
• 
To assess the safety and tolerability of oral FT011 compared to placebo in 
participants with diffuse SSc. 
• 
To evaluate the short-term efficacy of oral FT011 compared to placebo in 
improving disease activity in participants with diffuse SSc. 
 
 
 
 
 
 
 
 
 
 
 
 
 
Number of 
participants: 
Approximately 30 participants will be randomised and treated. 
Study design 
This is a multi-centre, randomised, double blind, placebo-controlled study to 
assess the pharmacokinetic pharmacodynamic effects and safety of FT011 in 
participants with diffuse systemic sclerosis. 
The targeted study population is patients with diffuse SSc with a disease duration 
of ≤10 years from onset of first non-Raynauds symptom, and a modified Rodnan 
Skin Score (mRSS) of 15 to 40 at the screening visit.  Patients meeting all eligibility 
criteria will have a baseline skin biopsy (2 x 3mm punch biopsies) taken before 
being randomised 1:1:1 to FT011 200mg, FT011 400mg, or placebo. 
Participants will take their investigational medicinal product (IMP) once a day for 
3 months (12 weeks), in addition to their standard-of-care scleroderma 
medications.  They will return to the site for study visits at Weeks 4, 8, and 12.  
Week 12 is the end of the study Treatment Period.  A final study follow-up visit 
will be conducted one month after they complete treatment (Week 16).

CONFIDENTIAL 
Visit procedures will include skin thickness assessments using the mRSS at every 
visit, and forced vital capacity (FVC), the Scleroderma Health Assessment 
Questionnaire- Disability Index (SHAQ-DI), and physician and patient global 
assessments at all visits during the Treatment Period.  A follow up skin biopsy will 
be taken at Week 12.  On Day 1 and at Week 12 participants will have serial PK 
samples collected out to 8 hours post-dose, and trough samples will be collected 
at each interim visit.  Other on-study visit assessments will include additional 
participant questionnaires, physical examinations, vital signs measurements, 
safety laboratory blood and urine tests, and electrocardiograms.  Adverse events 
and concomitant medications will be assessed and recorded at each study visit.  
Additional blood samples will be collected at Day 1 and Week 12 for exploratory 
assessments. 
With the exception of methotrexate, which is excluded, participants should be 
maintained on their current SSc medications during the course of the Treatment 
Period unless they meet the following progression criteria; those who have a 
mRSS increase from Baseline of 5 or more may start immunosuppressive 
medications, or, if already taking these, have their immunosuppressive 
medications or doses changed. 
A Data Safety Monitoring Board (DSMB) will review safety and PK data at agreed 
recruitment and progression milestones to provide independent oversight of 
participant safety.

Safety Monitoring 
and Oversight 
Participants with confirmed ALT or AST levels > 3 x ULN must have close 
observation that includes elicitation of a detailed history and performance of 
diagnostic lab studies to exclude other causes of acute liver injury.  In addition, 
they should have their liver chemistry (ALT, AST, ALP, international normalised 
ratio (INR) and total bilirubin) retested at least once weekly until levels normalise 
or return to baseline. 
In the event of confirmed laboratory results meeting any of following criteria, 
IMP will be stopped permanently for that participant: 
• 
ALT or AST >8 x ULN 
• 
ALT or AST >5 x ULN for more than 2 weeks 
• 
ALT or AST >3 x ULN and either bilirubin >2 x ULN or INR >1.5 
• 
ALT or AST >3 x ULN with the appearance of fatigue, nausea, vomiting, right 
upper quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%) 
If serum creatinine is ≥ Grade 3, IMP will be stopped for that participant and they 
will be monitored until values return to Grade 1.  IMP may then be restarted but 
stopped permanently if there is a recurrence of serum creatinine levels 
≥ Grade 3.

CONFIDENTIAL 
An independent DSMB will be established prior to recruitment start, with 
appropriate charter that defines its roles and responsibilities.  The DSMB will 
monitor accruing trial safety results, and PK data, at intervals throughout the 
study.  The main purpose of the DSMB will be to protect the safety interests of 
the participants included in the trial.  
If pre-defined study stopping rules are met, recruitment will be halted and the 
DSMB will review the data and advise whether recruitment and dosing may 
continue, or whether the study should be stopped. 
The charter will specify the intervals for formal DSMB meetings. 
The DSMB will convey to Certa Therapeutics Pty Ltd their recommendations as 
to whether the trial may continue as planned or if the trial should be modified or 
stopped.  The final decision on whether the study should be modified or stopped 
will be the responsibility of Certa Therapeutics Pty Ltd; any decision to modify or 
stop will be communicated to investigators and regulatory authorities (RA) by 
Certa Therapeutics Pty Ltd or their representatives. 
Statistical methods 
and analyses: 
Sample Size Justification 
The sample size for this study is sized based on practical considerations and no 
formal sample size calculation was performed.  A total of approximately 30 
participants, 10 per treatment group, will be randomised and treated. 
Statistical Analyses 
A statistical analysis plan (SAP) will be written and finalised prior to database 
lock.  The SAP will contain detailed and complete descriptions of the analyses 
that will be performed. 
Analysis Sets 
The following analysis sets will be defined: 
Intention-to-Treat (ITT) Set:  The ITT set is defined as all participants who were 
randomised.  Participants in this set will be analysed based on the treatment that 
they were randomised to. 
Safety Set:  The safety set is defined as all participants who were randomised and 
received at least one dose of study medication.  Participants in this set will be 
analysed based on the actual treatment that they received.  All safety analyses 
will be based on the safety set. 
Modified Intention-to-Treat (mITT) Set:  The mITT set is defined as all randomised 
participants who received at least one dose of study medication and who have 
post-baseline efficacy data for at least one of the outcome measures.  All efficacy 
analyses will be based on the mITT set. Participants in this set will be analysed 
based on the treatment that they were randomised to. 
PK Set:  The PK set is defined as all participants included in the safety set who 
have sufficient concentrations to allow for the calculation of at least one PK 
parameter. Participants who experience any adverse events or have protocol

deviations that could affect the PK profiles may be excluded from the PK set at 
the pharmacokineticist’s discretion. All PK analyses will be based on the PK set. 
Participants in this set will be analysed based on the actual treatment that they 
received. 
General Considerations 
Results will be presented by treatment group, pooled FT011 group and overall. 
In general, data will be summarised using descriptive statistics (number of 
observations, mean, median, standard deviation [SD], minimum and maximum) 
or frequency counts and percentages, as appropriate to the type of data. The 
coefficient of variation (CV), geometric mean and geometric CV will also be 
presented for the PK tables. 
Confidence intervals will be reported where appropriate. If not mentioned 
otherwise, all statistical tests will be performed with a type I two-sided error rate 
of 5%. 
Where appropriate, results will be presented graphically.  All reported data will 
be presented in data listing. 
The baseline value for each endpoint is defined as the last available, non-missing 
value obtained prior to the first study medication administration. 
The handling of missing data and adjustments for multiplicity will be described 
in the SAP. 
Pharmacokinetic Analyses 
All PK analyses will be based on the PK set. 
Descriptive statistics by nominal collection time will be presented for the PK 
concentrations. Concentrations will also be presented graphically on both linear 
and semi-logarithmic scales.  
The PK parameters will be calculated using non-compartmental analysis 
methods.  Full details will be provided in the SAP.   
Descriptive statistics will be presented for the PK parameters. 
Safety Analyses 
All safety analyses will be based on the safety set. 
Medical history findings and AEs will be coded by Medical Dictionary for 
Regulatory Activities (MedDRA) codes and medications the World Health 
Organisation Drug Dictionary (WHO-DD) Anatomical Therapeutic Chemical (ATC) 
classification codes. 
Treatment-emergent adverse events (TEAEs) are defined as AEs that started or 
worsen on or after the first study medication administration.  The incidence of 
TEAEs will be summarised by MedDRA terms and treatment group.  Drug-related, 
serious AEs (SAEs) and TEAEs leading to early study withdrawal will also be 
summarised.  Separate summaries will be produced based on severity and 
relationship to study drug categories.

BACKGROUND AND RATIONALE 
Investigators should be familiar with the current FT011 Investigator’s Brochure (IB). 
3.1 
Scleroderma 
Systemic sclerosis (SSc) is a rare and complex autoimmune disease, characterised by vascular damage, 
chronic inflammation, and fibrosis of the skin and internal organs.  The current treatment 
recommendations include the use of immunosuppressants, such as methotrexate, mycophenolate 
mofetil, and cyclophosphamide, for managing the symptoms and preventing complications in SSc 
patients1.  However, these treatments have poor efficacy and are associated with significant side 
effects, such as organ toxicities and serious infections.  Nintedanib, a multiple tyrosine kinase inhibitor 
recently approved for the treatment of systemic sclerosis-associated interstitial lung disease (SSc-ILD), 
slowed the rate of decline in lung function in SSc-ILD2.  Since no clinical benefit of nintedanib was 
observed for other manifestations of the disease, there remains an unmet need for safe and effective 
treatments in early diffuse SSc patients.

STUDY PLAN 
5.1 
Overall Trial Design 
This is a multi-centre, randomised, double blind, placebo-controlled study to assess the PK and PD 
effects and safety of FT011 in participants with diffuse systemic sclerosis. 
The targeted study population is patients with diffuse SSc with a disease duration of ≤10 years from 
onset of first non-Raynauds symptom, and a modified Rodnan Skin Score (mRSS) of 15 to 40 at the 
screening visit.  Patients meeting all eligibility criteria will have a baseline skin biopsy (2 x 3mm punch 
biopsies) taken before being randomised 1:1:1 to FT011 200mg, FT011 400mg, or placebo. 
Participants will take their investigational medicinal product (IMP) once a day for 3 months (12 weeks), 
in addition to their standard-of-care scleroderma medications.  They will return to the site for study 
visits at Weeks 4, 8, and 12.  Week 12 is the end of the study Treatment Period.  A final study follow-
up visit will be conducted one month after they complete treatment (Week 16). 
Visit procedures will include skin thickness assessments using the mRSS at every visit, and forced vital 
capacity (FVC), the Scleroderma Health Assessment Questionnaire- Disability Index (SHAQ-DI), and 
physician and patient global assessments at each visit during the Treatment Period.  A follow up skin 
biopsy will be taken at Week 12.  On Day 1 and at Week 12 participants will have serial PK samples 
collected out to 8 hours post-dose, and trough samples will be collected at each interim visit.  Other 
on-study visit assessments will include additional participant questionnaires, physical examinations, 
vital signs measurements, safety laboratory blood and urine tests, and electrocardiograms.  Adverse 
events and concomitant medications will be assessed and recorded at each study visit.  Additional 
blood samples will be collected at Day 1 and Week 12 for exploratory assessments. 
With the exception of methotrexate, which is excluded, participants should be maintained on their 
current SSc medications during the course of the Treatment Period unless they meet the following 
progression criteria; those who have a mRSS increase from Baseline of 5 or more may start 
immunosuppressive medications, or, if already taking these, have their immunosuppressive 
medications or doses changed. 
Safety rules are in place outlining actions to be taken based on liver function laboratory values.  In 
addition, a Data Safety Monitoring Board (DSMB) will review safety and PK data at agreed recruitment 
and progression milestones to provide independent oversight of participant safety. 
Figure 1, below, shows the study plan.

14. Other than SSc, have any other medical condition or significant co-morbidities, clinically relevant 
social or psychiatric conditions, or any finding during Screening, which in the investigator’s opinion 
may put the subject at risk or interfere with the study objectives. 
5.4.4 
Contraception requirements 
The reproductive and development effects of FT011 have not been tested.  Therefore, as a precaution, 
female participants should avoid becoming pregnant and male participants should avoid fathering 
children or donating sperm, for the duration of the study and at least three months after their last 
dose of IMP.  If a participant becomes pregnant during the study, IMP must be stopped permanently, 
and the participant withdrawn from the study. 
There is no requirement to use contraception if the participant or their sole partner is permanently 
sterile, according to one of the following criteria: 
• 
A female who has undergone surgical sterilisation (e.g., hysterectomy, bilateral salpingectomy, or 
bilateral salpingo-oophorectomy). 
• 
A female who is postmenopausal, defined as one year without menses without an alternative 
medical cause. 
• 
A male who has had bilateral orchidectomy. 
All other participants must be advised to use (or ensure their partner uses) at least one method of 
highly effective contraception (i.e., methods with a failure rate of less than 1% per year when used 
consistently and correctly) for the entire study period and for 3 months after their last dose of IMP.  
Such methods include: 
• 
Combined (estrogen and progestogen containing) hormonal contraception associated with 
inhibition of ovulation (oral, intravaginal, or transdermal)  
• 
Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, 
implantable) 
• 
Intrauterine device. 
• 
Intrauterine hormone-releasing system  
• 
bilateral tubal occlusion 
• 
vasectomised partner, provided that partner is the sole sexual partner of the female trial 
participant and that the vasectomised partner has received medical assessment of the surgical 
success 
• 
sexual abstinence defined as refraining from heterosexual intercourse, as the preferred and usual 
lifestyle of the subject. 
As potential interactions of FT011 with hormonal contraceptives have not been examined, male 
partners of WOCBP participants must also use a condom. 
Male participants with a partner who is a WOCBP must use a condom.

above, the participant will be asked to inform the investigator as soon as possible and consent to 
follow-up of the pregnancy outcome by Certa Therapeutics or designee. 
5.4.5 
Concomitant Medications and Treatments 
Methotrexate must not be taken within the 2 weeks prior to Day 1, or during the study. 
Participants should be maintained on their current SSc medications during the Treatment Period, 
unless they have a mRSS increase from Baseline of 5 or more.  In this case they may start 
immunosuppressive medications, or, if already taking those, have their immunosuppressive 
medications or doses changed. 
The following medications are exclusionary if taken during the specified pre-study period and should 
not be taken during the study treatment period. 
• 
Other anti-fibrotic agents including D-penicillamine or tyrosine kinase inhibitors (nilotinib, 
imatinib, dasatinib) in the month prior to Screening. 
• 
Biologic drugs such as TNF inhibitors, tocilizumab, or JAK inhibitors, in the 3 months prior to 
Screening. 
• 
Rituximab in the 6 months prior to Screening. 
• 
Cyclophosphamide oral or IV in the 3 months prior to Screening. 
• 
Oral prednisolone >10 mg per day or IV steroids in the month prior to Screening. 
 
 
 
 
If these medications are required to be used during the study Treatment Period, the investigator 
should discuss with the Medical Monitor whether the participant may remain on study or must be 
withdrawn. 
Any treatment or medication that is used, other than the IMP, must be noted in the source 
documentation and the Case Report Form (CRF).  This record should include the drug name, the dose 
and frequency, route of administration, the start and stop date of administration, and the indication. 
Medications or treatments taken in the 1 month prior to Baseline will be recorded on the prior 
medication CRF.  Any use of medications for the treatment of AE will be recorded on the concomitant 
medication CRF. 
5.4.6 
Study Restrictions 
There are no additional study restrictions. 
5.4.7 
Withdrawal of Participants from Study 
Participants can terminate their study participation at any time.  Participants who discontinue from 
the trial should always be asked about the reason(s) for their discontinuation and about the presence 
of any AEs. 
The Investigator or the Medical Monitor can exclude a participant from further taking part in the trial.

CONFIDENTIAL 
Possible reasons for discontinuing a participant may include: 
• 
Participant withdrawal of consent 
• 
Any unacceptable AEs, in the judgement of the Investigator 
• 
Participant’s non-compliance with the protocol 
• 
Certa Therapeutics terminates the study for financial or other reasons 
If a participant withdraws or is withdrawn, they should be encouraged to attend the follow up visit. 
5.4.8 
Stopping Rules / Discontinuation Criteria 
5.4.8.1 Individual Participant Stopping Rules 
Safety laboratory testing will be performed by a study central laboratory. 
If ALT or AST > 3 x ULN, the participant must have repeat testing conducted within 48 to 72 hours to 
confirm the values. 
If the elevation is confirmed as >3 x ULN, close observation that includes elicitation of a detailed history 
and performance of diagnostic laboratory studies to exclude other causes of acute liver injury must be 
conducted.  In addition, participants must have their liver chemistry (ALT, AST, ALP, international 
normalised ratio (INR) and total bilirubin) retested at least once weekly until levels normalise or return 
to baseline. 
In the event of confirmed laboratory results (i.e. confirmed on retest within 48 to 72 hours) meeting 
any of following criteria, IMP will be stopped permanently for that participant: 
• 
ALT or AST >8 x ULN 
• 
ALT or AST >5 x ULN for more than 2 weeks 
• 
ALT or AST >3 x ULN and either bilirubin >2 x ULN or INR >1.5 
• 
ALT or AST >3 x ULN with the appearance of fatigue, nausea, vomiting, right upper quadrant pain 
or tenderness, fever, rash, and/or eosinophilia (>5%). 
If serum creatinine is ≥ Grade 3 (based on the Common Terminology Criteria for Adverse Events 
(CTCAE)11), IMP will be stopped for that participant and they will be monitored until values return to 
Grade 1.  IMP may then be restarted but stopped permanently if there is a recurrence of serum 
creatinine levels ≥ Grade 3. 
All participants should attend the follow up visit 4 weeks after their last dose of IMP. 
5.4.8.2 Study Stopping Rules 
Recruitment will be halted and there will be an immediate review by the DSMB if any of the following 
conditions are met: 
• 
Three participants meet the same individual stopping rule. 
• 
Five participants meet any individual stopping rule. 
• 
There is any participant death assessed as related to IMP. 
The DSMB will review and recommend whether to continue recruitment and dosing, or to stop the 
study.  Participants who have not met any stopping rules may continue dosing while DSMB review is 
ongoing.

Additional stopping rules may be set by the DSMB. 
5.4.9 
 
Replacement of Participants 
Participants who are randomised but who withdraw prior to dosing will be replaced.  Additional 
participants may be enrolled into the study at the request of Certa Therapeutics to replace dropouts 
and ensure sufficient Week 12 PK samples are obtained for primary endpoint analysis.  Participants 
who withdraw due to AE will not be replaced.

5.5.2 
Packaging and labelling 
The IMP will be presented in white high-density polyethylene (HDPE) bottles, containing 70 capsules 
per bottle. 
Labelling is in accordance with applicable requirements for each country participating in the clinical 
trial. 
5.5.3 
Investigational Medicinal Product handling and storage 
IMP must be stored at 15 to 30°C (59 to 86°F) and protected from light and humidity. 
Prior to dispensing, all IMP supplies must be stored in a secure area with access limited to authorised 
staff.  The Principal Investigator (PI) or designee will ensure that the IMP at site is safely stored in 
compliance with the storage requirements.  The PI is responsible for ensuring that the IMP is dispensed 
in accordance with the protocol and only to participants randomised in the study. 
Authorised study personnel will dispense the IMP according to the randomisation schedule. 
5.5.4 
Accountability of study supplies 
All material supplied is for use only in this clinical study and should not be used for any other purpose.

CONFIDENTIAL 
The PI or designee is responsible for IMP accountability, reconciliation, and record maintenance.  The 
PI or designated site staff must maintain IMP accountability records throughout the course of the study 
including records of the amount of IMP received, the identification of the participant for whom the 
drug was dispensed, and the date(s) and quantity of the drug dispensed. 
The IMP and records must be available for inspection by a study monitor during the study.  Drug 
supplies, including unused, partially used or empty bottles, will either be returned by the Investigator 
or designee to Certa Therapeutics or their agent, or destroyed on site if written approval to do so is 
given by Certa Therapeutics and appropriate facilities and procedures are available.  Records shall be 
maintained by the Investigator of any disposition of the IMP.  These records must show the 
identification and quantity of IMP disposed of, the method of destruction (taking into account the 
requirements of local law), and the person who disposed of the IMP.  Where IMP is destroyed on-site, 
a record of destruction shall be issued and submitted to Certa Therapeutics. 
At the end of the trial an overall drug accountability will be performed to reconcile the number of 
dispensed and used/lost/returned IMP. 
5.5.5 
Doses and treatment regimen 
Approximately 30 participants, who fulfil all the entry criteria, will be randomised in the study. 
Participants will be randomly assigned to one of the following treatment arms: 
• 
200mg oral FT011 once per day for 3 months. 
• 
400mg oral FT011 once per day for 3 months. 
• 
Oral placebo once per day for 3 months. 
One dose consists of two (2) capsules. 
Participants will be instructed to take two (2) capsules once per day during the treatment period.  
Capsules should be taken on an empty stomach with a small amount of still water, at approximately 
the same time each morning. 
A vomited dose must not be replaced.  A double dose (e.g., missed dose from previous day and dose 
for current day) must not be taken. 
At each visit, the time of administration of the previous dose of IMP, and the time the dose is taken at 
the study site, must be recorded. 
5.5.6 
Method of assigning treatment 
A unique identification (ID) code will be allocated to each participant who provides informed consent, 
so that participants can be identified without making assumptions about their subsequent eligibility 
for the trial. 
If a participant fails screening and is not randomised, or discontinues from the trial, that ID will not be 
reused. 
Participants who fail screening and are approved to be rescreened will be allocated a new ID. 
As this is a double blind, placebo-controlled study, site staff, subjects, Certa Therapeutics, and 
delegates will be blinded as to which treatment each participant receives. 
Participant eligibility will be established before randomisation.  On Day 1, eligible participants will be 
randomised using an Interactive Response Technology (IRT) system.  At each IMP dispensing visit,

CONFIDENTIAL 
participants will be allocated a bottle number by the IRT system.  The participant, site, sponsor, and 
monitoring personnel will be blind to whether the subject is receiving FT011 or placebo. 
5.5.7 
Blinding and procedures for breaking the blind 
The IRT system will provide the option for an investigator to break the blind.  Sites will be instructed 
to break the blind only in situations in which the investigator determines that adequate medical care 
cannot be provided to a participant without knowing the treatment assignment.  If a code break must 
occur, the investigator or designee should advise the study Medical Monitor as soon as possible.  
Details for contacting the Medical Monitor will be provided in the Study Reference Manual (SRM).  If 
the code is broken for a subject, the IRT system will immediately notify Certa Therapeutics or their 
delegate. 
If the blind has been broken, the investigator must document the date and the reason the blind was 
broken in the subject’s notes and CRF. 
5.5.8 
Treatment Compliance 
Participant compliance will be assessed at each study visit by capsule count.  Participants will be 
considered compliant if they take ±10% of scheduled doses.  Participants who are non-compliant 
should be reminded of the dosing requirements and advised that they may be withdrawn from the 
study if compliance does not improve.

STUDY PROCEDURES 
6.1 
Participant Information 
The Investigator must provide adequate information regarding the study conduct and obtain written 
informed consent from the participant before any tests or investigations outlined in the study protocol 
are carried out. 
Prior to any study procedure, the participant will be asked to provide informed consent.  The 
participant will be given time to read and understand the Participant Information and Consent Form 
(PICF) and have any questions answered.  They may wish to take the PICF and consider it further, or to 
discuss it with their family or their usual doctor before signing. 
The PICF must be personally signed and dated by both the Investigator obtaining consent, and the 
participant. 
6.2 
Screening Visit (Day -28 to Day -1) 
The purpose of the Screening visit is to confirm participant eligibility against inclusion and exclusion 
criteria. 
In this study, participant eligibility must be determined within the 28 days prior to Day 1.  Screening 
assessments may be conducted on different days during the Screening period if required due to timing, 
or participant availability. 
Potential participants will attend the in-clinic screening.  Once informed consent has been obtained, 
the following visit assessments and procedures will be performed: 
• 
Review eligibility criteria. 
• 
Record participant demographic data.

TRIAL MEASUREMENTS 
8.1 
Pharmacokinetics 
Details of the laboratory and sample collection, processing, storage, and shipment are described in the 
Laboratory Manual. 
Blood samples for plasma PK analyses will be collected at the following time points: 
• 
Day 1:  within 30 minutes prior to IMP administration, and at 1, 2, 3, 4, 5, 6, 7 and 8 hours post 
dose. 
• 
Week 4:  within 30 minutes prior to IMP administration. 
• 
Week 8:  within 30 minutes prior to IMP administration. 
• 
Week 12:  within 30 minutes prior to IMP administration, and at 1, 2, 3, 4, 5, 6, 7 and 8 hours post 
dose. 
A window of ± 10 minutes is allowed for all time points.  Collections outside of these windows will be 
recorded as protocol deviations.  Actual collection time must be recorded. 
At each visit, the time of administration of the previous dose of IMP, and the time the dose is taken at 
the study site, must be recorded. 
The PK samples will be shipped to a central laboratory for determination of the pharmacokinetics of 
FT011. 
Metabolites may also be measured.  Remaining samples will be stored for up to 10 years and may be 
used for additional research into FT011 or relevant indication biomarkers. 
8.2 
Safety and tolerability 
Safety will be assessed by recording of AEs, laboratory parameters, vital signs, physical examination, 
and 12-lead ECG.  Where multiple procedures are scheduled for the same nominal time point, safety 
blood samples should be taken after all other procedures have been performed. 
• 
The physical examination will include the following: examination of general appearance, skin, 
head, neck (including thyroid), eyes, ears, nose, throat, heart, lungs, abdomen, lymph nodes, 
extremities, and nervous system.  Height will be recorded at screening only.  A symptom directed 
physical examination will be conducted at post-screening visits, based on signs and symptoms the 
patient has experienced or reported.

• 
Vital sign measurements should be taken after the participant has rested in a supine position for 
at least 5 minutes and include blood pressure (systolic and diastolic), heart rate (beats/minute), 
respiratory rate, and body temperature.  The same arm (preferably the nondominant arm) and the 
appropriate size cuff should be used for each blood pressure measurement. 
o At the Day 1 and Week 12 visits, vital signs are to be recorded pre-dose and just prior to 
the 8-hour post dose PK sample. 
• 
12-lead ECGs will be performed.  Participants should be in a resting supine position for 10 minutes 
prior to ECG collection.  The Investigator (or a qualified observer at the investigational site) will 
interpret the ECG using one of the following categories: within normal limits, abnormal but not 
clinically significant, or abnormal and clinically significant.  The heart rate from the ECG machine 
should not be used as part of the vital sign measurements. 
• 
Blood and urine samples will be taken throughout the course of the study.  On-study collections 
should be fasted.  Details of the laboratory and sample collection, processing, storage, and 
shipment are described in the Laboratory Manual.  The following specific tests will be performed 
at the study central laboratory: 
o Haematology: Haemoglobin, haematocrit, red blood cell count, red cell distribution width,

Participants will be questioned at each visit from Day 1 about any AEs they may have experienced 
since the previous visit.  See Section 10.3 for further details on recording AEs. 
• 
Participants will be questioned at each visit about any concomitant medications they may have 
taken since the previous visit.  This will assist in identifying AEs.

Efficacy 
• 
The mRSS is a validated physical evaluation of patient's skin thickness rated by clinical palpation 
using a 0-3 scale (0 = normal skin; 1 = mild thickness; 2 = moderate thickness; 3 = severe thickness 
with inability to pinch the skin into a fold for each of 17 surface anatomic areas of the body: face, 
anterior chest, abdomen, and, with right and left sides of the body separately evaluated, the 
fingers, forearms, upper arms, thighs, lower legs, dorsum of hands and feet. Individual values are 
summed and defined as the total skin score.  Total score is 0 to 51 with higher scores indicating 
worse symptomology.  Minimally clinically significant difference in MRSS is 3-5 points.12

Percent predicted FVC is calculated using equations incorporating age, gender, and race.  It is 
calculated as (FVC Observed / FVC predicted) x 100, where FVC predicted is calculated relative to 
a reference population.  Forced expiratory manoeuvres will be performed at least in triplicate with 
the minimal requirement that three manoeuvres are "acceptable" and that two of these 
manoeuvres meet end-of-test and repeatability criteria for FVC and FEV1. 
• 
The SHAQ-DI consists of 20 questions referring to eight component sets consisting of 
dressing/grooming, arising, eating, walking, hygiene, reach, grip, and activities.  Each item is scored 
on a 4-point scale from 0 to 3: 0 = Without any difficulty; 1 = With some difficulty; 2 = With much 
difficulty; 3 = Unable to do.  The eight scores of the eight sections are summed and divided by 8.  
If one section is not completed by a subject, the summed score is divided by 7.  The total score 
indicates the patient's self-assessed level of disability - higher scores indicate worse 
symptomology.  This outcome measure represents the change in mean score from baseline.  A 
negative change from baseline indicates improvement.  The Scleroderma HAQ (SHAQ) includes an 
additional five scleroderma‐specific visual analogue scales (VAS), addressing overall disease 
activity, Raynaud's phenomenon, finger ulcers, breathing, and intestinal problems.  A composite 
VAS score is not created nor are the individual VAS scores incorporated into the HAQ DI score. 
• 
The Patient's Global Assessment represents the patient's overall assessment of current SSc status 
on a 100-mm horizontal VAS, ranging from 0 on the extreme left end of the scale indicating 
"extremely poor health", and 100 on the extreme right end indicating "excellent health". 
• 
The Physician's Global Assessment is to be completed based on examination and overall 
assessment of the patient.  The physician's assessment of the patient's SSc status will be scored on 
a 100-mm horizontal VAS, ranging from 0 on the extreme left end of the scale indicating "no 
disease activity" (symptom free), and 100 on the extreme right end indicating "worst imaginable 
disease activity". 
• 
The ACR CRISS was developed using expert consensus and data driven approaches for use in clinical 
trials.13,14  The exponential algorithm determines the predicted probability of improvement from 
baseline, incorporating change in the mRSS, FVC percent predicted, physician and patient global 
assessments, and HAQ-DI.  The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%).  
A higher score indicates greater improvement. 
The application of CRISS algorithm in a randomised clinical trial is a 2-step process. 
In the first step, participants will be clinically evaluated to determine whether the participant has 
improved or not. A participant is considered not improved and is assigned a probability score of 
improving equal to 0.0, irrespective of improvement on other core items, if he/she develops:  
1. New scleroderma renal crisis. 
2. Decline in FVC % predicted ≥15% (relative), confirmed by another FVC % within a month, 
high resolution computed tomography (HRCT) to confirm interstitial lung disease (if previous 
HRCT did not show interstitial lung disease) and FVC % predicted below 80% predicted 
(attributable to SSc). 
3. New onset of left ventricular failure (defined as ejection fraction ≤45%) or new onset of 
pulmonary arterial hypertension requiring treatment (attributable to SSc).

If the participant is determined to exhibit improvement in the first step (i.e., not assigned a 0.0), 
the second step involves computing the predicted probability of improving (a score between 0.0 
and 1.0, inclusive) using the equation: 
 
where ΔMRSS indicates the change in mRSS from baseline to the visit, ΔFVC denotes the change in 
FVC % predicted from baseline to the visit, ΔPt-glob indicates the change in patient global 
assessment, ΔMD-glob denotes the change in physician global assessment, and ΔHAQ-DI is the 
change in HAQ-DI.  Note that all changes are absolute changes. 
Participants for which the predicted probability is greater or equal to 0.60 are considered 
improved, while participants for which the predicted probability is below 0.60 are considered not 
improved.

STUDY OVERSIGHT 
9.1 
Data Safety Monitoring Board 
An independent DSMB will be established prior to recruitment start, with appropriate charter that 
defines its roles and responsibilities.  The DSMB will monitor accruing trial safety results and PK data 
at intervals throughout the study.  The main purpose of the DSMB will be to protect the interests of 
the participants included in the trial. 
The charter will specify the intervals for formal DSMB meetings. 
The DSMB will convey to Certa Therapeutics their recommendations as to whether the trial may 
continue as planned or if the trial should be modified or stopped.  The final decision on whether the 
study should be modified or stopped will be the responsibility of Certa Therapeutics.  Any decision to 
modify or stop will be communicated to investigators and regulatory authorities (RA) by Certa 
Therapeutics (or their representatives).  The DSMB may also report PK data in a blinded fashion. 
The DSMB will also review any serious adverse events (SAE) that occur during the study. 
Certa Therapeutics may also decide to cease enrolment at any time if unfavourable safety data lead to 
the conclusion that the benefit-risk assessment for the trial is no longer positive. 
10 ADVERSE EVENTS 
The definitions of AEs and SAEs are given below.  It is extremely important that all staff involved in the 
trial are familiar with the content of this section.  The PI is responsible for ensuring this. 
AEs and SAEs will be captured from the time of the first dose of IMP through to the final study visit. 
10.1 Adverse Event Definitions 
An AE is defined as any untoward medical occurrence in a participant or clinical investigation 
participant administered a pharmaceutical product and which does not necessarily 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 (investigational) product whether or not related to the medicinal (investigational) product. 
Laboratory reference ranges are defined by upper or lower limits of parameters of the respective 
laboratory.  The Investigator should ensure that each parameter out of the normal range is assessed 
for clinical significance and potential for being an AE.  It is at the discretion of the Investigator to 
document any change in laboratory result as an AE if he considers the change to be clinically significant, 
even if the absolute value is within the alert limit or reference range. 
The participant must be instructed to inform the Investigator about all AEs and these must be 
documented in the participant records and CRF together with their intensity: 
• 
Severe are those AEs which make normal daily routine impossible. 
• 
Moderate AEs impact the normal daily routine. 
• 
Mild AEs do not impact normal daily routine. 
An AE that is assessed as severe should not be confused with a SAE.  Severity is a category utilised for 
rating the intensity of an event, and both AEs and SAEs can be assessed as severe.  An event is defined 
as ‘serious’ when it meets one of the pre-defined outcomes as described in Section 10.2.

Version:  2.1

Page 43 of 55 
 
CONFIDENTIAL 
The Investigator must assign causality to each adverse event in relation to IMP based on the following 
scale: 
• 
Not related:  AE for which there is evidence of another explanation, e.g. the adverse event is 
obviously explained by the participant’s disease(s), is in accordance with the known effect of a 
concomitant medication, or has occurred prior to first administration of FT011. 
• 
Unlikely related:  AE with a time relationship to FT011 administration that makes a relationship 
improbable (but not impossible), and disease or other drugs provide plausible explanations. 
• 
Possibly related:  AE with a reasonable time relationship to FT011 administration, but which could 
also be explained by disease or other drugs.  Information on FT011 withdrawal may be lacking or 
unclear. 
• 
Probably related:  AE with reasonable time relationship to FT011 administration that is unlikely to 
be attributed to disease or other drugs.  Response to FT011 withdrawal is clinically reasonable.  
Rechallenge is not required. 
• 
Definitely related:  AE with plausible time relationship to FT011 administration which cannot be 
explained by disease or other drugs.  Response to FT011 withdrawal is plausible 
(pharmacologically, 
pathologically), 
and 
event 
is 
definitive 
pharmacologically 
or 
phenomenologically (i.e. an objective and specific medical disorder or a recognised 
pharmacological phenomenon).  Rechallenge, if performed/necessary, is satisfactory. 
All AEs must be documented by the Investigator, regardless of causality. 
If an AE leads to premature discontinuation of the study, the appropriate pages of the CRF must be 
completed. 
Expected AEs are defined in the IB reference safety information.  At this stage of development there 
are no expected AEs defined for FT011. 
10.2 Serious Adverse Events 
An AE shall be classified as serious if it: 
• 
Results in death. 
• 
Is life-threatening. 
Life threatening in the definition of serious refers to an event in which the participant was at risk 
of death at the time of the event, it does not refer to an event which hypothetically might have 
caused death if it were more severe. 
• 
Requires inpatient hospitalisation or prolongation of existing hospitalisation. 
Hospitalisation is defined as inpatient admission or care regardless of duration. 
Out-patient treatment in an emergency room is not in itself an SAE, although the reasons for it 
may be (e.g. bronchospasm, laryngeal oedema).  Elective surgery, hospitalisation for social reasons 
(with no causing AE), or hospital admissions and/or surgical operations planned before or during 
this study are not considered AEs if the illness or disease existed before the participant was 
enrolled in the study, provided that it did not deteriorate in an unexpected way during the study. 
• 
Results in persistent or significant disability/incapacity.

• 
Is a congenital anomaly/birth defect. 
• 
Is an important medical event. 
This includes events that may not be immediately life-threatening or result in death or 
hospitalisation but may jeopardise the participant or may require intervention to prevent one of 
the other outcomes listed above. 
10.3 Eliciting and Recording of Adverse Events 
At every study visit, participants must be asked a standard, non-directed question, such as, “How have 
you been feeling since your last visit?” to elicit any medically related changes in their well-being.  They 
may also be asked if they have been hospitalised, had any accidents, used any new medications, or 
changed concomitant medication regimens (including prescription drugs, over-the-counter 
medications, vitamins, herbal products, and minerals).  Responses must be documented in the source 
documents. 
In addition to patient observations, AEs must be documented for any clinically significant diagnosis 
resulting from abnormal laboratory test values, physical examination findings, or ECG abnormalities, 
or from other documents that are relevant to participant safety. 
AEs will be captured from the time of first IMP dose, until the final study visit.  Conditions occurring 
prior to the first dose of IMP will be recorded as medical history.  SAEs judged to be possibly related to 
FT011 occurring to a study participant after the SAE reporting period will be reported to the sponsor if 
the Investigator becomes aware of them. 
It is preferable that AEs are reported as diagnoses if one can be made, rather than individual signs and 
symptoms. The AE description, start and stop dates, intensity, causality, and outcome must be 
recorded, as well as any actions taken. 
Unless a diagnosis is made, or signs and symptoms are present, abnormal laboratory values, physical 
examination findings, abnormal vital signs, or ECG abnormalities, should only be reported as AEs if they 
cause the participant to discontinue from the trial, the investigator feels it is clinically significant, or 
they meet a criterion for a SAE. 
10.4 Reporting Serious Adverse Events 
10.4.1 Reporting to Sponsor 
Investigators and other site personnel must report SAEs on a SAE form to Certa Therapeutics or their 
designee within 24 hours of becoming aware of the SAE, regardless of causality.  Information regarding 
SAEs will be entered in to the electronic CRF, confirmed by a physician from the study site, and 
transmitted within 24 hours.  If the electronic CRF is inaccessible, SAE reports (paper form) should be 
submitted by email to 
within the same timelines. 
Follow-up information on SAEs must also be reported by the investigational site within the same time 
frame.  If a non-serious AE becomes serious, this and other relevant follow-up information must also 
be provided within 24 hours. 
All SAEs will be recorded in the participant records and the CRF.

CONFIDENTIAL 
10.4.2 Reporting to Regulatory Authorities, Ethics Committees/Institutional Review Boards, and 
Investigators 
Certa Therapeutics or their designee will report SAEs, AEs that are both serious and unexpected and 
are considered to be related to the administered product (suspected unexpected serious adverse 
reactions [SUSARs]), and Safety Issues to RAs in accordance with applicable laws and regulations. 
The investigator must comply with any applicable site-specific requirements related to the reporting 
of SAEs (and in particular deaths) involving his/her subjects to the EC/IRB that approved the trial.  In 
accordance with ICH GCP guidelines, the sponsor will inform the investigator of ‘findings that could 
adversely affect the safety of subjects, impact the conduct of the trial, or alter the EC’s/IRB’s 
approval/favourable opinion to continue the trial.’  In particular and in line with respective regulations, 
the sponsor will inform the investigator SUSARs.  The investigator should retain copies of safety reports 
in the Investigator Site File (ISF). 
When specifically required by regulations and guidelines, the sponsor will provide appropriate safety 
reports directly to the concerned lead EC/IRB and will maintain records of these notifications.  When 
direct reporting by the sponsor is not clearly defined by national or site-specific regulations, the 
investigator will be responsible for notifying the relevant EC/IRB of any safety reports as required, 
within the period specific by the EC/IRB, and of filing copies of all related correspondence in the ISF. 
10.5 Follow-up of Adverse Events and Serious Adverse Events 
All AEs and all SAEs must be followed by the Investigator until resolution, until the AE stabilises or is 
recognised as a permanent condition by the Investigator, or until the participant is lost to follow up, 
whichever comes first.  Follow-up investigations may be necessary according to the Investigator’s 
medical judgement. 
10.6 Pregnancy Reporting 
If a participant or their partner becomes pregnant, they will be asked to consent to follow up of the 
pregnancy and outcome.  Pregnancy will be recorded on a pregnancy notification form. 
Certa Therapeutics or designee will follow-up on the outcome of the pregnancy and the health status 
of the neonate, including after study completion. 
11 DATA MANAGEMENT 
11.1 Data Management and Quality Control 
A 21 CFR Part 11 compliant Electronic Data Capture (EDC) system will be used to capture data for all 
patients entered in the study.  Data collection and entry into the CRF will be completed by authorised 
study site personnel designated by the Investigator.  Appropriate training will be completed with the 
Investigator and all authorised study site personnel prior to the study being initiated and any data 
being entered into the CRF for any study participants. 
All data must be entered in English.  The CRFs should always reflect the latest observations on the 
participants participating in the trial; therefore, the CRFs are to be completed as soon as possible after 
the participant’s visit.  The Investigator must verify that all data entries in the CRFs are accurate and 
correct.  If some assessments are not done, or if certain information is not available or not applicable 
or unknown, this should be indicated in the CRF.  The PI (or designee) will be required to sign off on 
the CRF data.

CONFIDENTIAL 
The study monitor/Clinical Research Associate (CRA) will review the CRFs and evaluate them for 
completeness and consistency and compare them to the source documents to ensure that there are 
no discrepancies between critical data.  All entries, corrections and alterations are to be made by the 
responsible Investigator or designee.  The CRA cannot enter data into the CRFs.  If corrections are 
needed, the CRA or Data Manager will query the site. 
The CRF is essentially a data entry form and should not constitute the original, or source document, 
unless otherwise specified.  Source documents are all documents used or obtained by the Investigator 
or trial site that relate to the participant’s medical history, that verify the existence of the participant, 
the inclusion and exclusion criteria and all records covering the participant’s participation in the study.  
They include, but are not limited to, laboratory reports, pharmacy dispensing records, hospital records, 
participant files, etc. 
The Investigator is responsible for maintaining source documents.  These will be made available for 
inspection by the CRA at each monitoring visit. 
12 STATISTICAL ANALYSIS CONSIDERATIONS 
A Statistical Analysis Plan (SAP) will be written and approved prior to database lock.  The SAP (as an 
extension of the protocol) will detail the implementation of all the planned statistical analyses in 
accordance with the principal features stated in the protocol.  Methodology described in the SAP will 
take precedence over the protocol.  Any deviations from the analyses described in the SAP will be 
presented in the final clinical study report. 
12.1 Determination of Sample Size  
The sample size for this study is sized based on practical considerations and a formal sample size 
calculation was not performed.  A total of approximately 30 participants, 10 per treatment group, will 
be randomised and treated.  The sample size is considered sufficient to assess the study objectives. 
12.2 General Methodology 
Results will be presented by treatment group, for the pooled FT011 group and overall. 
In general, data will be summarised using descriptive statistics (number of observations, mean, 
median, standard deviation [SD], minimum and maximum) or frequency counts and percentages, as 
appropriate to the type of data.  The coefficient of variation (CV), geometric mean and geometric CV 
will also be presented for the PK tables. 
Confidence intervals will be reported where appropriate.  If not mentioned otherwise, all statistical 
tests will be performed with a type I two-sided error rate of 5%. 
Baseline will be defined as the last available, valid, non-missing assessment prior to the first study drug 
administration. 
Only data from protocol scheduled visits/time points will be included in the summary tables.  Data 
from unscheduled visits/time points will be included in the figures (where appropriate) and data 
listings. 
Medical history and adverse event terms will be coded by Medical Dictionary for Regulatory Activities 
(MedDRA) codes and prior and concomitant medications by the World Health Organisation Drug 
Dictionary (WHO-DD) Anatomical Therapeutic Chemical (ATC) classification codes.  The specific 
dictionary versions will be documented in the SAP and in the outputs.

12.3 Analysis Sets 
The following analysis sets will be defined: 
Intention-to-Treat (ITT) Set:  The ITT set is defined as all participants who were randomised.  
Participants in this set will be analysed based on the treatment that they were randomised to. 
Safety Set:  The safety set is defined as all participants who were randomised and received at least one 
dose of study medication.  Participants in this set will be analysed based on the actual treatment that 
they received.  All safety analyses will be based on the safety set. 
Modified Intention-to-Treat (mITT) Set:  The mITT set is defined as all randomised participants who 
received at least one dose of study medication and who have post-baseline efficacy data for at least 
one of the efficacy outcome measures.  All efficacy analyses will be based on the mITT set.  Participants 
in this set will be analysed based on the treatment that they were randomised to. 
PK Set:  The PK set is defined as all participants included in the safety set who have sufficient 
concentrations to allow for the calculation of at least one PK parameter.  Participants who experience 
any adverse events or have protocol deviations that could affect the PK profiles may be excluded from 
the PK set at the pharmacokineticist’s discretion.  All PK analyses will be based on the PK set.  
Participants in this set will be analysed based on the actual treatment that they received. 
12.4 Analyses 
12.4.1 Baseline Characteristics and Disposition 
Participant enrolment and disposition will be summarised by treatment group and will include the total 
number of participants randomised into the study and in included into each of the defined analysis 
sets.  The number of participants who prematurely discontinuing from the study, along with the reason 
for early discontinuation will also be summarised. 
Demographic and other baseline characteristics data recorded at screening and prior to dosing will be 
summarised, by randomised treatment group. 
All analyses will be based on the ITT set. 
12.4.2 Safety Analysis 
All safety analyses will be based on the safety set. 
12.4.2.1 Adverse Events 
AEs will be grouped by MedDRA system organ class and preferred term and summarised, by treatment 
group.  The summary tables will present the number and percentage of total participants and number 
of events, by system organ class and by preferred term. 
For the summaries of AEs, participants who experience the same AE (in terms of the MedDRA preferred 
term) more than once will only be counted once for that event in the number of participants but all 
occurrences of the same event will be counted in the number of events. 
All AE summaries will be restricted to treatment emergent AEs only.  Treatment emergent AEs are 
defined as AEs which commence on or after the first study drug administration.

Separate summaries will be produced based on severity and relationship to study drug categories. 
All adverse events data will be listed. 
12.4.2.2 Duration of Exposure and Compliance 
Exposure and compliance data will be summarised and listed. 
12.4.2.3 Laboratory Results 
Laboratory data will be summarised and listed by treatment group and visit.  Actual values and the 
changes from baseline will be presented.  In addition, ‘shift from baseline’ tables will also be presented 
showing the changes in the reference range classifications (normal, low, high) over time. 
Dipstick urinalysis results evaluation (normal or, abnormal not clinically significant or abnormal 
clinically significant) will be summarised by treatment group and visit using frequency tabulations. 
Abnormal laboratory values (including clinical significance as assessed by the Investigator) will be 
flagged in the listings. 
12.4.2.4 Vital Signs and Physical Examination 
Vital signs will be summarised and listed by treatment group and visit.  Actual values and the changes 
from baseline will be presented. 
Physical examination findings will only be listed. 
12.4.2.5 12-lead ECG Results 
ECG measurement will be summarised and listed by treatment group and visit.  Actual values and the 
changes from baseline will be presented. 
In addition, a frequency tabulation of overall ECG interpretation (normal or, abnormal not clinically 
significant or abnormal clinically significant) will be summarised by treatment group and visit using 
frequency tabulations. 
12.4.2.6 Prior and Concomitant Medications 
Prior and concomitant medications will be grouped by the WHO-DD ATC classification Level 2 term and 
by preferred drug name. 
Prior medications are those medications that were stopped prior to the first study drug administration.  
Concomitant medications are medications that are taken at least once after the first study drug 
administration.  Medications stopping on the same day as the first study drug administration will be 
considered as concomitant medications. 
12.4.3 Pharmacokinetic Analysis 
The analysis of the plasma FT011 PK concentrations and parameters data will be based on the PK set. 
Results will be presented by visit (Day 1 and Week 12) and treatment group.

12.4.3.1 Pharmacokinetic Concentrations 
Plasma FT011 concentrations data will be summarised by visit and nominal collection time points using 
descriptive statistics including the number of concentrations below the limit of quantification (BLQ), 
CV, geometric mean, and geometric CV. 
Results reported as BLQ will be treated as zero for the calculation of the summary statistics, and as 
missing for the calculation of the geometric statistics. 
Spaghetti plots of the individual plasma FT011 concentrations vs. actual time profiles (relative to the 
dose at the visit) will be presented on linear and log-linear scales.  Plots will be presented by treatment 
group and visit.  BLQ concentrations will be set to 0 in the linear plots and will be treated as missing in 
the log-linear plots. 
Mean concentration profiles (± SD bars) vs. nominal time curves will be presented by visit on linear 
and log-linear scales.  All treatment groups will be presented in the same plot. 
All plasma FT011 concentration data will be listed, and the listing will include the calculated elapsed 
time since the study drug administration at the specific visit and the time deviations between the 
actual and planned sample collection times. 
12.4.3.2 Pharmacokinetic Parameters 
Two sets of plasma FT011 PK parameters will be calculated based the concentrations collected after 
the single dose on Day 1 and based on the concentrations collected after the last dose at Week 12. 
Plasma PK parameters will be calculated using a non-compartmental approach based on the observed 
concentration-time profiles.  Actual sampling times relative to the dose at the visit will be used in all 
PK calculations.  The handling of BLQ values in the parameter calculations will be described in the SAP. 
The plasma PK parameters shown in Table 3 will be calculated (data permitting) from the 
concentration-time profiles and additional parameters may be added at the discretion of the 
pharmacokineticist

All plasma PK parameter results will be listed. 
12.4.4 Efficacy Analysis  
All efficacy analyses will be based on the mITT set. 
Whilst no formal hypothesis testing is planned, exploratory analyses may be performed to assess the 
treatment effect of FT011 on the efficacy outcomes.  Full details of any inferential analyses will be 
provided in the SAP. 
The handling of missing data and adjustments for multiplicity will be described in the SAP. 
All collected and derived results will be presented in the data listings. 
12.4.4.1 Continuous Endpoints 
The actual results and the change from baseline values at each post-baseline visit will be summarised 
by treatment group using descriptive statistics. 
The mean change from baseline values (±SD) over time will also be presented graphically. 
The change from baseline values will be compared between the FT011 and placebo groups using a 
mixed model repeated measures model with the baseline value a covariate, treatment group as fixed 
effect, the interaction effect between study visit and treatment group, and subject as random effect 
with an unstructured covariance assumption.  Parameter estimates will be calculated using restricted 
maximum likelihood methods, and the Kenward-Rogers method will be used to calculate the degrees 
of freedom. 
The least squares means, estimated treatment differences (compared to placebo) and the 
corresponding confidence intervals and p-values at each visit will be presented. 
The numeric CRISS scores be analysed using a Wilcoxon test. 
12.4.4.2 Binary Endpoints 
Binary endpoints will be summarised using counts, percentages, and odds ratios (compared to 
placebo).  The proportions between each FT011 group and the placebo group will be compared using 
a Cochran-Mantel-Haenszel test. 
12.4.4.3 Categorical Endpoints 
Categorical endpoints will be summarised using counts and percentages.

CONFIDENTIAL 
Before the start of the trial, a representative of Certa Therapeutics or designee will contact the 
investigational site to ensure facilities are adequate and discuss responsibilities with the site staff with 
regards to following the protocol and regulatory and ethical requirements. 
During the trial, a CRA from Certa Therapeutics or its designee will regularly visit the site to monitor 
and confirm protocol, regulatory and ethical adherence, confirm data accuracy and provide 
information and support as needed. 
In agreement with Certa Therapeutics and the PI, monitoring activities may take place remotely.  The 
conduct of remote monitoring visits should not replace the conduct of on-site visits entirely.  If on-site 
monitoring visits are no longer possible, the use of central and remote monitoring programs will be 
used to maintain oversight of clinical sites. 
The PI agrees to allow the CRA direct access to all relevant documents, including electronic medical 
records, and to allocate his time and the time of his staff to the CRA to discuss findings and any relevant 
issues. 
Site staff will be provided with CRA and back up contact details in the event they have queries or 
require assistance. 
13.3 Audits and Inspections 
An audit is a systematic and independent examination of trial related activities and documents to 
determine whether the evaluated trial related activities were conducted, and the data were recorded, 
analysed, and accurately reported according to the protocol, Certa Therapeutics SOPs and those of 
Certa Therapeutics designees, GCP, and applicable regulatory requirements. 
Authorised representatives of Certa Therapeutics, its designee, a RA, or the EC may visit the centre to 
perform audits or inspections.  The investigator should contact Certa Therapeutics or designee 
immediately if they are contacted by a RA about an inspection at their centre.  If an audit or inspection 
occurs, the PI and institution agree to allow the auditor/inspector direct access to all relevant 
documents and allocate their time and the time of their staff to the auditor/inspector to discuss 
findings and any relevant issues. 
13.4 Training of Staff 
Each individual involved in conducting a trial should be qualified by education, training, and experience 
to perform his or her respective tasks. 
Site staff may be trained for this study at meetings and initiation and study visits by Certa Therapeutics, 
or their designees. 
The PI will maintain records of all individuals involved in the trial at their site.  The PI will ensure that 
appropriate training relevant to the trial is given to all these staff, and that they will receive any new 
information relevant to the performance of this trial in a timely manner. 
13.5 Changes to the Protocol 
Trial procedures will not be changed without the agreement of Certa Therapeutics. 
If it is necessary for the trial protocol to be amended, the amendment or a new version of the trial 
protocol must be notified to or approved by the relevant RA if applicable, and by the site’s EC/IRB 
before implementation at the site, unless the safety of participants is involved.  Local requirements 
must be followed.

If a protocol amendment requires a change to the PICF, approval of the revised PICF by Certa 
Therapeutics or their designee and by the EC/IRB and RA if applicable is required before the revised 
form can be used. 
Certa Therapeutics or their designee will distribute amendments and new versions of the protocol to 
the PI and to the appropriate RAs as required.  The PI will be responsible for submitting to their EC/IRB. 
13.6 Trial Agreements 
The PI and institution must comply with all the terms, conditions, and obligations of the trial agreement 
for this trial.  In the event of any inconsistency between this protocol and the trial agreement, the trial 
agreement shall prevail. 
13.7 Trial Timetable and Termination 
The planned start date for this trial is first quarter 2021, and the proposed completion data is third 
quarter 2022. 
Certa Therapeutics reserves the right to terminate the trial at any stage for any reason including 
commercial considerations. 
13.8 Ethics Review 
The protocol and the PICF will be submitted for approval to the appropriate EC/IRB and RA if applicable 
and must be approved or given a favourable opinion in writing as appropriate.  In addition, the EC/IRB 
must approve any other written information to be provided to participants, including advertising used 
to recruit participants for the trial.  The investigator must submit written EC/IRB approval to Certa 
Therapeutics or designee before they can enrol any participant into the trial.

1. INTRODUCTION 
 
This document describes the rules and conventions to be used in the presentation and analysis of 
pharmacokinetic (PK), pharmacodynamic (PD), and safety data for Protocol CER-FT011-SSc01 version 
2.1, dated 01 November 2021. It describes the data to be summarized and analysed, including 
specifics of the statistical analyses to be performed. 
A subset of the analyses described in this SAP will form the basis of reports provided to the Data Safety 
Monitoring Board (DSMB) while the study is ongoing. The tables and listings prepared for the DSMB 
are additionally identified in the Table, Listing and Figures Template document that accompanies this 
SAP. It is recognised that this analysis plan may be modified by the study team as new information 
becomes available outside of the study, or to reflect recommendations made by DSMB. In addition, 
some analyses, tables or listings may be omitted at DSMB if there are insufficient data to warrant 
analysis or at the request of the DSMB. Where the SAP is updated after initial approval, the changes 
will result in a new version and a brief description in the Modification History of this SAP. 
This statistical analysis plan (SAP) is based on protocol Version 2.1 dated 01 November 2021, DSMB 
charter version 1.0 dated 15 July 2021 and eCRF Version 7.3 dated 10 November 2021.

3. STUDY DESIGN 
 
3.1. GENERAL DESCRIPTION 
This is a multi-centre, randomised, double blind, placebo-controlled study to assess the PK and PD 
effects and safety of FT011 in participants with diffuse SSc. 
A total of approximately 30 participants, 10 per treatment group, will be randomised and treated. The 
sample size for this study is sized based on practical considerations and a formal sample size 
calculation was not performed. 
The targeted study population is participants with diffuse SSc with a disease duration of ≤10 years 
from onset of first non-Raynauds symptom, and a modified Rodnan Skin Score (mRSS) of 15 to 40 at 
the screening visit. Participants meeting all eligibility criteria will have a baseline skin biopsy (2 x 3 mm 
punch biopsies) taken before being randomised 1:1:1 to FT011 200 mg, FT011 400 mg, or placebo. 
Participants will take their study drug once a day for 3 months (12 weeks), in addition to their 
standard-of-care scleroderma medications. They will return to the site for study visits at Weeks 4, 8, 
and 12. Week 12 is the end of the study Treatment Period. A final study follow-up visit will be 
conducted one month after they complete treatment (Week 16). 
Visit procedures will include skin thickness assessments using the mRSS at every visit, and forced vital 
capacity (FVC), the Scleroderma Health Assessment Questionnaire-Disability Index (SHAQ-DI), and 
Physician and Patient Global Assessments at all visits during the Treatment Period. A follow up skin 
biopsy will be taken at Week 12. On Day 1 and at Week 12 participants will have serial PK samples 
collected out to 8 hours post-dose, and trough samples will be collected at each interim visit. Other 
on-study visit assessments will include additional participant questionnaires, physical examinations, 
vital signs measurements, safety laboratory blood and urine tests, and electrocardiograms. Adverse 
events and concomitant medications will be assessed and recorded at each study visit. 
Additional blood samples will be collected at Day 1 and Week 12 for exploratory assessments. 
With the exception of methotrexate, which is excluded, participants should be maintained on their 
current SSc medications during the course of the Treatment Period unless they meet the following 
progression criteria; those who have a mRSS increase from Baseline of 5 or more may start 
immunosuppressive medications, or, if already taking these, have their immunosuppressive 
medications or doses changed.

3.2. SCHEDULE OF EVENTS 
Schedule of events can be found in section 2, Table 1 of the protocol. 
 
3.3. CHANGES TO ANALYSIS FROM PROTOCOL 
There are two planned changes to this SAP that aren’t included in protocol: 
1) The SAP includes the addition of an All Participants Screened Set, which is used for disposition 
reporting. 
2) The patient global assessment scores will be inverted for the CRISS calculations. This is 
described in section 14 of the SAP. 
 
4. PLANNED ANALYSES 
 
4.1. DATA SAFETY MONITORING BOARD 
An independent DSMB will be established prior to recruitment start, with appropriate charter that 
defines its roles and responsibilities. The DSMB will monitor accruing trial safety results and PK data 
at intervals throughout the study. The main purpose of the DSMB will be to protect the interests of 
the participants included in the trial. 
The DSMB will convey to Certa Therapeutics their recommendations as to whether the trial may 
continue as planned or if the trial should be modified or stopped. The final decision on whether the

study should be modified or stopped will be the responsibility of Certa Therapeutics. Any decision to 
modify or stop will be communicated to investigators and regulatory authorities (RA) by Certa 
Therapeutics (or their representatives). The DSMB may also review PK data in a blinded fashion. 
The DSMB will also review any serious adverse events (SAE) that occur during the study. 
The DSMB meetings will be held when data is available at the following time points: 
• First meeting will be scheduled after 10 participants have been randomised, or at 6 months 
after start of recruitment, whichever is earlier. 
• Second meeting will be scheduled after 10 participants have completed treatment. 
• Third meeting will be scheduled after 20 participants have completed treatment. 
Meetings will be scheduled for approximately three weeks after the data cut off to allow time for 
preparation of summaries, tables and listings. 
As outlined in the DSMB charter, two separate reports will be prepared and distributed as follows for 
each DSMB meeting. The summary below provides details of the relevant sections of this analysis plan 
that are relevant to each report, a broader description of the planned analyses that will be provided 
at each DSMB review can be found in the relevant sections of the charter. 
The proposed tables and listings proposed for the DSMB appears in Appendix 4 of the charter and are 
reproduced in Appendix 3 of the SAP. The full structure is presented in the Tables, Listings and Figure 
Templates. 
Open Session: Distributed to the DSMB members, Certa Therapeutics and others as requested by the 
DSMB. Data presented in the open sessions will not identify the dosing regimens of the participants. 
The report will include analyses from the following section of this analysis plan pooled over the 
treatment groups unless specified otherwise. 
• Information on participant recruitment (provided by Project Manager) 
• Protocol Changes (provided by Project Manager) 
• Eligibility/Protocol Deviations (provided by Project Manager) 
• Study disposition 
• Baseline demographics 
• Baseline scleroderma signs and symptoms

5.4. SAFETY ANALYSIS SET 
The Safety Analysis Set will include all randomised participants who received at least one dose of study 
drug. Participants in this set will be analysed based on the actual treatment that they received. All 
safety summaries will be based on the Safety Analysis Set. 
 
5.5. PHARMACOKINETIC ANALYSIS SET 
The pharmacokinetic (PK) Analysis Set will include all participants included in the safety set who have 
sufficient concentrations to allow for the calculation of at least one PK parameter. Participants who 
experience any adverse events or have protocol deviations that could affect the PK profiles may be 
excluded from the PK analysis set at the pharmacokineticist’s discretion. Participants in this set will be 
analysed based on the actual treatment that they received. All PK analyses will be based on the PK 
Analysis Set. 
 
6. GENERAL CONSIDERATIONS 
 
Listings will be presented using All Participants Enrolled Set for those participants with data available. 
 
6.1. SUMMARY STATISTICS 
For categorical variables, the population size (N for population group totals and n for available data 
for each treatment group) and the percentage (of available data) for each class of the variable will be 
presented. Continuous variables will be summarized using descriptive statistics, including number of 
participants (n), mean, standard deviation (SD), median, minimum, and maximum values. The 
coefficient of variation (CV%), geometric mean and geometric CV% will be presented for the PK tables. 
95% Confidence Intervals will be reported where appropriate. If not mentioned otherwise, all 
statistical tests will be performed with a type I two-sided error rate of 5%. 
 
6.2. TREATMENT SUMMARIZATION 
Results will be presented for each treatment group, for the pooled FT011 group and overall. 
 
6.3. PRECISION 
All continuous demographic and safety variables (i.e., clinical laboratory values, vital signs, body 
weight and ECG intervals), including derivations thereof, will be reported to the same precision as the 
source data. 
For the reporting of descriptive statistics, the mean and median will be presented to one digit more 
than the source data. The standard deviation will be presented to two digits more than the source 
data. The minimum and maximum will be presented to the same precision as the source data.

PK data (concentration-time and PK parameters) will be presented to three significant digits. 
Percentages will be reported to one decimal point. 
6.4. REFERENCE START DATE AND STUDY DAY 
Study Day will be calculated from the date of first study drug administration and will be used to show 
start/stop day of assessments and events. 
• If the date of the event is on or after the date of first study drug administration then: 
Study Day = (date of event – date of first study drug administration) + 1 
• If the date of the event is prior to the date of first study drug administration then: 
Study Day = (date of event – date of first study drug administration) 
There will be no Study Day 0. 
In the situation where the event date is partial or missing, study day and any corresponding durations 
will appear partial or missing in the listings. 
 
6.5. BASELINE 
In general, baseline is defined as the last available, valid, non-missing measurement taken prior to first 
study drug administration (including unscheduled assessments). In the case where the last non- 
missing measurement and the reference start date coincide, that measurement will be considered 
pre-baseline, but adverse events (AEs) and medications commencing on the reference start date will 
be considered post-baseline. 
 
6.6. ON-TREATMENT 
A participant will be identified as on-treatment if the last available, valid, non-missing measurement 
taken prior to cut-off date indicates the participant is receiving a study drug. 
 
6.7. RETESTS, UNSCHEDULED VISITS AND EARLY TERMINATION DATA 
Unscheduled measurements will not be included in summaries at each protocol specified time point. 
However, unscheduled assessments will be taken into consideration in the calculation of baseline 
values. 
Early termination results will be recorded as such and included with the end-of-study summaries. 
In the case of a retest of a scheduled assessment, the retested measurement for that scheduled time 
(i.e., the original assessment) will be used for summaries unless flagged as invalid. 
In the case of duplicate tests with the same sample date/time (in particular, where a lab sample is 
analysed at two separate labs), for quantitative results, the mean of the values will be used in the

summary tables and for qualitative results, the most abnormal of the values will be used in the 
summary tables. The listings will present the duplicate values. 
Data from unscheduled visits/time points will be included in the figures (where appropriate) and data 
listings. 
 
6.8. WINDOWING CONVENTIONS 
No visit windowing will be performed for this study. 
 
6.9. STATISTICAL TESTS 
 
Where indicated, two-sided confidence intervals will be assessed at the 5% significance and two-sided 
p-value will be reported. 
 
6.10. COMMON CALCULATIONS 
For continuous measurements: 
Actual change from baseline will be calculated as: 
• Test Value at Visit X (after baseline) – Baseline Value 
6.11. SOFTWARE VERSION 
All derivations, statistical analyses, summaries and listings will be generated using SAS version 9.4 or 
higher (SAS Institute, Inc., Cary, North Carolina). PK Parameters will be calculated using WinNonlin

14. PHARMACOKINETIC, EFFICACY AND PHARMACODYNAMIC ANALYSIS 
 
14.1. PHARMACOKINETIC ANALYSIS 
Pharmacokinetic data collected and analysed will be presented as described in this section. All PK 
analysis will be presented using the PK Analysis set. 
 
14.1.1 PHARMACOKINETIC SAMPLE COLLECTION 
Blood samples for plasma PK analyses will be collected at the following time points: 
• Day 1: within 30 minutes prior to IMP administration, and at 1, 2, 3, 4, 5, 6, 7 and 8 hours post 
dose. 
• Week 4: within 30 minutes prior to IMP administration. 
• Week 8: within 30 minutes prior to IMP administration. 
• Week 12: within 30 minutes prior to IMP administration, and at 1, 2, 3, 4, 5, 6, 7 and 8 hours post 
dose. 
A window of ± 10 minutes is allowed for all time points. Collections outside of these windows will be 
recorded as protocol deviations. Actual collection time must be recorded. At each visit, the time of 
administration of the previous dose of IMP, and the time the dose is taken at the study site, must be 
recorded. 
 
14.1.2 PHARMACOKINETIC CONCENTRATIONS 
Plasma FT011 (and any metabolite) concentrations data will be summarised by visit and nominal 
collection time points using descriptive statistics including the number of concentrations below the limit 
of quantification (BLQ), CV%, geometric mean, and geometric CV%. 
Results reported as BLQ will be treated as zero for the calculation of the summary statistics, and as 
missing for the calculation of the geometric statistics. 
Spaghetti plots of the individual plasma FT011 concentrations vs. actual time profiles (relative to the 
dose at the visit) will be presented on linear and log-linear scales. Plots will be presented by treatment 
group and visit. BLQ concentrations will be set to 0 in the linear plots and will be treated as half of lower 
limit of quantification (0.5*LLOQ) in the log-linear plots. 
Mean concentration profiles (± SD bars) vs. nominal time curves will be presented by visit on linear and 
log-linear scales.

All plasma FT011 concentration data will be listed, and the listing will include the calculated elapsed 
time since the study drug administration at the specific visit and the time deviations between the actual 
and planned sample collection times. 
 
14.1.3 PHARMACOKINETIC PARAMETERS 
Two sets of plasma FT011 PK parameters will be calculated based on the concentrations collected after 
the single dose on Day 1 and based on the concentrations collected after the last dose at Week 12. 
Plasma PK parameters will be calculated using a non-compartmental approach (Phoenix WinNonlin 
version 8.3 or higher) based on the observed concentration-time profiles. Actual sampling times relative 
to the dose at the visit will be used in all PK calculations. The PK set will be used for the pharmacokinetic 
parameter calculations. The following PK parameters will be determined for FT011 and additional 
parameters may be added at the discretion of the pharmacokineticist. 
 
PK Parameter 
Method 
Cmax 
Maximum observed concentration 
tmax 
Time to reach maximum concentration 
AUC0-8 
Area under the plasma concentration-time curve from the time of the dose 
administration to the time of the 8-hour post-dose concentration 
calculated by the linear up log down trapezoidal method 
AUClast 
Area under the concentration-time curve from the time of the dose 
administration to the time of the last measurable concentration calculated 
by the linear up log down trapezoidal method 
 
All predose BLQ values will be substituted by zeros. Thereafter BLQ values will be set as “missing”. 
The plasma PK parameter results will be summarised by treatment group and visit using summary 
statistics and the geometric statistics described for the PK concentrations. All plasma PK parameter 
results will be listed. 
 
Results will also be presented graphically using box-and-whisker plots. 
 
14.2. EFFICACY ANALYSIS 
All efficacy analysis will be presented using the mITT Analysis set. The statistical comparisons 
described in this SAP for the efficacy variables are exploratory only, and no formal hypotheses testing 
will be undertaken. 
 
14.2.1 EFFICACY VARIABLES AND DERIVATION 
 
14.2.1.1 MODIFIED RODNAN SKIN SCORE (MRSS) 
The mRSS is a validated physical evaluation of participant's skin thickness rated by clinical palpation

using a 0-3 scale (0 = normal skin; 1 = mild thickness; 2 = moderate thickness with difficulty in making 
skin folds and no wrinkles; 3 = severe thickness with inability to pinch the skin into a fold) for each of 
17 surface anatomic areas of the body: face, anterior chest, abdomen, and with right and left sides of 
the body separately evaluated, the fingers, forearms, upper arms, thighs, lower legs, dorsum of hands 
and feet. Individual values are summed and defined as the total skin score. Total score is 0 to 51 with 
higher scores indicating worse symptomology. Minimally clinically significant difference in mRSS is 3- 
5 points.1 
 
14.2.1.2 PERCENT PREDICTED FORCED VITAL CAPACITY (FVC) 
Percent predicted FVC is calculated using equations incorporating age, sex, and race. It is calculated 
as (FVC Observed / FVC Predicted) x 100, where FVC predicted is calculated relative to a reference 
population. Forced expiratory manoeuvres will be performed at least in triplicate with the minimal 
requirement that three manoeuvres are "acceptable" and that two of these manoeuvres meet end- 
of-test and repeatability criteria for FVC and forced expiratory volume in 1 second (FEV1). 
 
14.2.1.3 SCLERODERMA HEALTH ASSESSMENT QUESTIONNAIRE-DISABILITY INDEX (SHAQ-DI) 
The SHAQ-DI consists of 20 questions referring to eight domains of activity: dressing/grooming, arising, 
eating, walking, hygiene, reach, grip, and activities. Each item is scored on a 4-point scale from 0 to 3: 
0 = without any difficulty; 1 = with some difficulty; 2 = with much difficulty; 3 = unable to do. 
The highest (0 is lowest, 3 is highest) score reported by a patient for any individual item in each of the 
domains is the score for that domain. Additionally, for each category if the patient indicates that they 
have used an aid or device, then the minimum score for that domain is 2. If the domain is previously 
scored as 3, then the domain score is 3. For example, if the highest score for dressing/grooming is ‘1’ 
and the patient says that they use a device for dressing, then the domain score for dressing/grooming 
would be set to ‘2’. 
The overall composite SHAQ-DI (Standard Disability Index) for a patient is derived as the average of the 
computed domain scores (where the domain scores are set as described above), with the denominator 
based on the number of domains in which the patient has provided a response. 
The composite score indicates the participant's self-assessed level of disability - higher scores indicate 
worse symptomology. The outcome is the change in mean score from baseline. A negative change from 
baseline indicates improvement. 
The Scleroderma HAQ (SHAQ) includes an additional five scleroderma‐specific visual analogue scales 
(VAS), addressing overall disease activity, Raynaud's phenomenon, finger ulcers, breathing, and 
intestinal problems. A composite VAS score is not created nor are the individual VAS scores incorporated 
into the HAQ DI score. 
 
14.2.1.4 PATIENT GLOBAL ASSESSMENT SCORE 
The Patient's Global Assessment represents the patient's overall health status on a 100-mm horizontal

VAS, ranging from 0 on the extreme left end of the scale indicating "extremely poor health status", 
and 100 on the extreme right end indicating "excellent health status". 
 
14.2.1.5 PHYSICIAN GLOBAL ASSESSMENT SCORE 
The Physician's Global Assessment is to be completed based on examination and overall assessment 
of the participant. The physician's assessment of the participant's SSc status will be scored on a 100- 
mm horizontal VAS, ranging from 0 on the extreme left end of the scale indicating "no disease activity" 
(symptom free), and 100 on the extreme right end indicating "worst imaginable disease activity". 
 
14.2.1.6 COMPOSITE RESPONSE INDEX IN DIFFUSE CUTANEOUS SYSTEMIC SCLEROSIS (CRISS) 
The ACR CRISS was developed using expert consensus and data driven approaches for use in clinical 
trials.2,3 The exponential algorithm determines the predicted probability of improvement from 
baseline, incorporating change in the mRSS, FVC percent predicted, physician and patient global 
assessments, and HAQ-DI. The outcome is a continuous variable between 0.0 and 1.0 (0 - 100%). A 
higher score indicates greater improvement. 
The application of CRISS algorithm in a randomised clinical trial is a 2-step process. 
In the first step, participants will be clinically evaluated to determine whether the participant has 
improved or not. A participant is considered not improved and is assigned a probability score of 
improving equal to 0.0, irrespective of improvement on other core items, if he/she develops: 
1. New scleroderma renal crisis. 
2. Decline in FVC % predicted ≥15% (relative), confirmed by another FVC % within a month, high 
resolution computed tomography (HRCT) to confirm interstitial lung disease (if previous HRCT 
did not show interstitial lung disease) and FVC % predicted below 80% predicted (attributable 
to SSc). 
3. New onset of left ventricular failure (defined as ejection fraction ≤45%) or new onset of 
pulmonary arterial hypertension requiring treatment (attributable to SSc). 
If the participant is determined to exhibit improvement in the first step (i.e., not assigned a 0.0), the 
second step involves computing the predicted probability of improving (a score between 0.0 and 1.0, 
inclusive) using the equation: 
 
where ΔMRSS indicates the change in mRSS from baseline to the visit, ΔFVC denotes the change in 
FVC % predicted from baseline to the visit, ΔPt-glob indicates the change in patient global assessment, 
ΔMD-glob denotes the change in physician global assessment, and ΔHAQ-DI is the change in HAQ-DI. 
Note that all changes are absolute changes. Additionally, Pt-glob will be calculated as 100-reported 
score. ΔPt-glob and ΔMD-glob will be divided by 10.

Participants for which the predicted probability is greater or equal to 0.60 are considered improved, 
while participants for which the predicted probability is below 0.60 are considered not improved. 
 
14.2.1.7 SCLERODERMA CLINICAL TRIALS CONSORTIUM DAMAGE INDEX (SCTC-DI) 
The SCTC-DI is a 23-item composite damage index to quantify organ damage in systemic sclerosis (0- 
55 scale: >5 moderate damage, >12 severe damage). The total SCTC-DI score is reported on the eCRF. 
 
14.2.1.8 5-D ITCH SCALE 
The 5-D itch scale is a validated brief multidimensional questionnaire designed to be useful as an 
outcome measure in clinical trials. The five dimensions are degree, duration, direction, disability, and 
distribution. 
 
14.2.1.9 MISSING DATA METHODS FOR EFFICACY VARIABLE 
Missing data will not be imputed, unless otherwise stated. 
 
14.2.1.10 ANALYSIS OF EFFICACY VARIABLES 
The observed values and change from baseline values for mRSS, percent predicted FVC, HAQ-DI, 
patient global assessment score, and physician global assessment score, and SCTC-DI score will be 
listed for each participant at each protocol specified visit and will be summarised using descriptive 
statistics over time by treatment group and for all participants. 
Actual and change from baseline values will be presented graphically by treatment group using a jitter 
plot and overlaid box-whisker plot (median, 25th and 75th percentiles) over time. 
For mRSS, HAQ-DI, SCTC-DI and 5-D Itch Scale the individual item responses will also be summarised 
and listed for each participant. 
The 5-D itch scale at baseline and at Week 12 will be listed for each participant and will be summarised 
using descriptive statistics. The change from baseline to Week 12 will also be summarised. 
Even though no formal hypothesis testing is planned for this study, exploratory analyses may be 
performed to assess the treatment effect of FT011 on the efficacy outcomes if data indicates trend 
and model assumptions hold. 
For mRSS, percent predicted FVC, HAQ-DI, patient global assessment score, and physician global 
assessment score, the change from baseline values will be compared between the FT011 and placebo 
groups using a mixed model for repeated measures with the baseline value as a covariate, treatment 
group as fixed effect, the interaction effect between study visit and treatment group, and participant 
as random effect using an unstructured covariance structure. Parameter estimates will be calculated 
using restricted maximum likelihood methods (REML), and the Kenward-Rogers method for 
determining the degrees of freedom. This method will assume that any missing data is Missing at 
Random (MAR). Example SAS code for the mixed model (using SAS Proc Mixed) is:

15. SAFETY OUTCOMES 
 
All safety summaries will be based on the Safety Analysis Set. 
There will be no statistical comparisons between the treatment groups for safety outcomes. 
 
15.1. ADVERSE EVENTS 
AEs will be coded to system organ class (SOC) and preferred term (PT) using MedDRA central coding 
dictionary, Version 23.0 (or higher). 
Treatment-emergent adverse events (TEAEs) are defined as AEs which commence or worsen on or 
after the date and time of first study drug administration. AEs without an onset date and time will be 
defined as treatment-emergent except if an incomplete date (e.g., month and year) clearly indicates 
that the event started prior to start of first study drug administration or if the AE stop date indicates 
that the event started and/or stopped prior to start of first study drug administration. 
All Adverse Events (AEs) summaries will be restricted to the TEAEs only. The number and percentage 
of TEAEs, Serious TEAEs, TEAEs leading to discontinuation of study treatment and study, and TEAEs 
related to study treatment will be summarized by SOC, PT and treatment group. The number and 
percentage of TEAEs by maximum severity will also be summarized. 
An overall summary of the number and percentage of participants who had events in each of the 
categories described below will be produced by treatment group and for all participants. 
The following AE summaries will be provided: 
• 
Overview of TEAEs, including: 
o 
At least one TEAE 
o 
At least one study treatment related TEAE 
o 
At least one serious TEAE 
o 
At least one study treatment related serious TEAE 
o 
Any TEAE leading to death 
o 
TEAE leading to study discontinuation 
o 
TEAE leading to study drug withdrawal 
o 
TEAE leading to study drug interruption 
o 
At least one TEAE by maximum severity 
o 
At least one study treatment related TEAE by maximum severity

Incidence of study treatment related TEAEs by maximum severity 
• 
Incidence of serious TEAEs by SOC and PT 
• 
Incidence of study treatment related serious TEAEs by SOC and PT. 
In the summary tables, AEs will be presented by decreasing frequency of total participants overall 
within each SOC and then similarly by decreasing frequency of total participants overall within each 
PT. SOC or PTs with equal frequencies will be sorted alphabetically. 
An overall summary of number of participants within each of the categories described in the sub- 
section below, will be provided as specified in the templates. 
The overall Listing of adverse events will include TEAEs and Non-TEAEs. All other listings will include 
TEAEs only. 
 
15.1.1 ALL TEAES 
Incidence of TEAEs will be presented by SOC and PT and broken down further by maximum severity 
and relationship to study treatment. In these tables, SOC and PT will be presented by decreasing 
frequency. 
 
15.1.1.1 
SEVERITY 
Adverse event severity is classified as mild, moderate, or severe. TEAEs starting after the first dose of 
study treatment with a missing severity will be classified as severe. If a participant, reports a TEAE 
more than once within that SOC/ PT, the AE with the worst-case severity will be used in the 
corresponding severity summaries. 
 
15.1.1.2 
RELATIONSHIP TO STUDY TREATMENT 
Relationship to study treatment, as assessed by the Investigator, is classified as definitely related, 
probably related, possibly related, unlikely related or not related. TEAEs reported as having a 
definitely related, probably related, or possibly related relationship to study treatment are classified 
as related. TEAEs with a missing or unknown relationship to study treatment will be considered related 
to study treatment. If a participant, reports the same AE more than once within that SOC/ PT, the AE 
with the worst relationship to study treatment will be used in the corresponding relationship 
summaries. 
 
15.1.1.3 
TEAES LEADING TO STUDY DRUG INTERRUPTION 
TEAEs leading to drug interruption will be identified by using the variable pertaining to action taken 
with study treatment on the AE page of the eCRF indicated as ‘Drug interrupted’ and all TEAEs meeting 
this criteria will be listed separately.

Central safety laboratory results will be included in the reporting of this study for haematology, 
biochemistry, coagulation, urinalysis, and serum pregnancy testing. No lab data imputation will be 
performed. Incomplete data may be excluded from some analyses. In cases where an analysis depends 
on identifying an abnormal value, only values which are non-missing and which can be clearly 
identified programmatically as abnormal will be counted. 
Presentations will use SI Units, as provided by the laboratory. 
Quantitative laboratory measurements reported as “<X”, i.e. below the lower limit of quantification, 
or “> X”, i.e. above the upper limit of quantification, will be converted to X for the purpose of 
quantitative summaries, but will be presented as recorded, i.e. as “<X” or “> X” in the listings. 
Laboratory data will be summarized using descriptive statistics. Clinical laboratory data collected 
during study conduct, which were not required per protocol, such as for special testing to evaluate an 
AE, will be listed and not summarized. 
All laboratory data is summarised and listed for all visits where data is collected. The following 
summaries are provided for laboratory data: 
Actual values and change from baseline will be summarized using descriptive statistics at each 
protocol specified time point, by treatment group.
