1. Incorporation of Administrative Letter/
Amendment dated 01 May 2019
a) Change of Inclusion Criterion # 3a.
All subjects, including the subjects that meet the
diagnosis of NASH with a previous liver biopsy,
will undergo a FibroScan at screening. This is
necessary as FibroScan is considered an endpoint
and a pre-treatment (screening) result is necessary
to evaluate the change from baseline to C4/D22.
Section 2.0 Study Summary, section 7.1 Inclusion
Criteria
(Comment: This criterion is further amended
under # 3 in this amendment [protocol version
2.0])
b) Change of number for rescheduling options at
check-in from 2 to 1.
Section 9.1.12 Check-in Procedure
c) Clarification of Exclusion Criterion #26. The
timepoint “1 year” was accidentally omitted in the
protocol and was re-added again.
Section 2.0 Study Summary, section 7.2 Exclusion
Criteria
d) Adjustments of language in order to comply
with Clinical Data Interchange Standards
Consortium (CDISC) controlled terminology for
electronic datasets.
Section 10.3.3 Action Taken and Outcome
f) Adjustments of “X-marks” in the Schedule of
Events to be consistent with protocol language.

h) Clarification of terms
Gastrointestinal was added in order to ensure that
gastrointestinal system for the baseline physical
examination is the same as the abdominal
assessed at the abbreviated PE.
Section 9.1.4 Physical Examination
2. Incorporation of Administrative Letter dated
29 May 2019
a) Capturing of SAEs was changed. From now
on, SAEs will be entered electronically via EDC
with an autogenerated email. The email will be
sent to 
 Pharmacovigilance (PV) after
completion and saving of an AE, with choosing
the options “serious=yes”. The paper SAE report
form is only to be utilized if the site is unable to
access EDC for any reason.
Section 10.2 Recording of Adverse Events and
Serious Adverse Events, section 10.4.2 Serious
Adverse Events and Suspected Unexpected
Serious Adverse Serious Reactions (SUSARs)
Changes for this Amendment: 
3. Change of Inclusion Criterion # 3a
LSM by FibroScan is deleted as an inclusion
criterion. A FibroScan CAP value of ≥ 300 dB/m
is still required as part of the eligibility criteria.
LSM as entry criterion is eliminated, as it is
specific for a progressive NASH. The FibroScan
can be performed at screening or within 30 days
prior to screening.
Section 2.0 Study Summary, section 7.1 Inclusion
Criteria, 9.1.2 Screening, 9.1.17.4 FibroScan,
section 16.1, Appendix A
4. Change of Inclusion Criterion # 6c
Fasting plasma glucose (FPG) at screening was
changed from < 180 mg/dL to < 240 mg/dL, in
order to align with protocol section 9.1.14 Wash-
Out Period

provided by local imaging centers on 
contraindications. 
Section 2.0 Study Summary, section 7.2 Exclusion 
Criteria 
2. Change of Specified Timepoint for Prohibited
Medications
Any medication that is a strong inducer or strong
inhibitor of CYP3A4, is prohibited from 15 days
prior to dosing unless half-life is greater than 72
hours, then it is prohibited for 5 half-lives prior to
dosing. The timepoint of 30 days prior to dosing
has been adjusted to the above statement to
accommodate for the various drugs and half-lives.
Section 7.3.1 Prohibited Medications
3. Allowing to Collect Additional Samples
Covering all Types of Tissues for Potential
Future Analysis
Additional samples (e.g., including blood
samples, urine samples and all types of tissue
samples) may be collected and stored for potential
future analysis.

Samples
4. Incorporation of Updated IB, version 5.0
Updated language from IB and reference to
updated version have been incorporated
throughout the protocol.

but recorded as medical history, as these pre-
existing conditions are found as a result of the 
screening procedure.

7. Recording of Deuterated Water Intake
Missed doses of deuterated water will be entered
into the CRF to check compliance.
Section 8.5.1 Deuterated Water
8. Compliance of IP Intake
In order to achieve appropriate coverage of IP,
subjects are not allowed to miss more than a
specific number of doses during their dosing
cycles. If subjects are non-compliant, they may be
excluded from the study.
Section 8.5 Dose Regimen
9. Exclusion of Cannabidiol Oil as Concomitant
Drug
Cannabidiol is a CYP inhibitor and will be added
to the list of CYP3A4 inhibitors and inducers. It
is covered under “other food components” in the
Exclusion Criteria.
Section 16.3, Appendix C
10. Adjustment of Blood Volume
Blood sampling for PK assessments will need 2.0
mL per sample instead of the projected 3.0 mL
per sample. This leads to a reduction of the total
blood volume for the study.
Section 9.1.16 Pharmacokinetic Assessments and
Schedule
11. Adding Hyperglycemia to Blood Glucose
Measurement at Hyperglycemia
Subjects’ blood glucose might be measured by
fingerstick whenever there are signs or symptoms
of hypoglycemia or hyperglycemia.
Hyperglycemia was added to ensure that subjects
blood glucose is monitored across all ranges for
the safety of the subject.

examination 
• Change from baseline in vital signs (blood pressure [BP], 
heart rate [HR], respiratory rate, and temperature]) 
• Change from baseline in 12-lead electrocardiogram (ECG) 
parameters 
To assess the preliminary efficacy of FT-4101 on liver fat after 
administration of multiple doses in overweight/obese subjects with 
NASH by: 
• Reduction (absolute and relative) of % liver fat on magnetic 
resonance imaging-estimated proton density fat fraction 
(MRI-PDFF) at 12 weeks 
Secondary 
Objectives 
and 
Endpoints 
To assess the preliminary efficacy of FT-4101 on liver fat after 
administration of multiple doses in overweight/obese subjects with 
NASH by: 
• Reduction (absolute and relative) of % liver fat on MRI-PDFF 
at 6 weeks 
• Proportion of subjects experiencing a relative reduction of 
30% or greater of % liver fat at week 12 as assessed by MRI-
PDFF 
To assess the pharmacodynamic (PD) effect of FT-4101 on circulating 
biomarkers of liver inflammation after administration of multiple 
doses in overweight/obese subjects with NASH by: 
• Reduction of liver biochemistry marker: Alanine

Study 
Population 
Overweight/Obese subjects with NASH 
Number of 
Subjects 
At least 30 subjects, divided in 2 cohorts with at least 15 subjects per 
cohort. Drop-outs may be replaced in order to enroll sufficient 
subjects into the study, only after discussion with Sponsor and 
Investigator. 
Summary of 
Study Design 
This is a Phase 1/2, randomized, double-blind, placebo-controlled 
study evaluating the safety, tolerability and preliminary efficacy of an 
intermittent treatment with 3.0 mg and 4.5 mg FT-4101 over 12 
weeks in overweight/obese subjects with NASH. 
The study may be conducted in up to 2 dosing cohorts, that will 
overlap. Cohorts will enroll 15 subjects each, randomized to FT-4101 
or placebo in a ratio of 2:1 (10 on active, 5 on placebo). Cohort A will 
assess the administration of a dose of 3.0 mg FT-4101 given for 2 
weeks, alternating with a 1 week of no investigational product (IP), 
continued for 12 weeks. This design leads to 4 dosing cycles (2-week 
daily IP followed by 1 week of no IP).  After Cohort A (3.0 mg FT-
4101) received 6 weeks of treatment (2 dosing cycles), a dose 
escalation meeting will be held and an advancement to Cohort B (4.5 
mg FT-4101) will only be approved after the safety and tolerability 
data from Cohort A (3.0 mg FT-4101) are determined to be 
acceptable. Cohort B will be administered up to 4.5 mg FT-4101 with 
the same dosing design as in Cohort A. All subjects will undergo a 
screening visit, a run-in period, followed by multiple outpatient visits, 
2 in-house treatment periods, and a follow-up visit. An optional wash-
out period prior to dosing may be performed for subjects with T2DM 
on oral antidiabetic combination therapy. Safety, tolerability, PK and 
PD assessments will be performed throughout the study. Hepatic 
steatosis will be performed by MRI-PDFF. Hepatic and sebum DNL 
will be assessed using a 2-week deuterated water labelling protocol. 
Sebum and blood samples for additional PD and PK assessments will 
be collected throughout the study. For detail on all assessments, 
please see the Schedule of Events (SOE) in section 16.1.

Sample Size 
A sample size of 15 subjects per cohort is empirically determined to 
assess the safety of the dose and characterize the PK.   
The total number of subjects will be approximately 30; 20 treated 
with FT-4101 and 10 with placebo.  With 10 evaluable subjects in the 
treated group and 10 evaluable subjects in the control group, there is 
84% power to detect a difference of 20% between the high dose 
treated group (cohort B) and the pooled placebo subjects from cohorts 
A and B in MRI-PDFF, assuming a standard deviation of 14% using a 
one-sided Wilcoxon-Mann-Whitney test with an alpha of 0.05. 
Statistical 
Methods 
Data analyses will follow a statistical analysis plan (SAP). 
The overall safety profile of FT-4101 will be assessed as the 
percentage of participants experiencing TEAE, serious TEAEs, 
TEAEs leading to premature study drug discontinuation, and 
treatment-emergent clinically significant laboratory abnormalities. 
Safety analysis will involve examination of the descriptive statistics 
and individual subject listings for any effects of study treatment on 
clinical tolerability and safety. 
Efficacy, PK and PD assessments for all dose groups will be analysed 
using descriptive methods; figures (bar charts or line plots) may also 
be generated to visualize the data. 
The primary preliminary efficacy analysis of the reduction (absolute 
and relative) of % liver fat on magnetic resonance imaging-estimated 
proton density fat fraction (MRI-PDFF) at 12 weeks will be analyzed 
using a Wilcoxon rank-sum test. The test will be one-sided and use a 
significance level of 0.05.  Subjects in each dose group will be tested 
against the pooled placebo subjects from each cohort. 
If more than one dose of FT-4101 is evaluated, control of the alpha 
level will be accomplished using Holm’s Sequential Bonferroni 
procedure [Holm 1979] to test each FT-4101 dose against the pooled 
placebo subjects. 
The secondary preliminary efficacy analysis of the reduction 
(absolute and relative) of % liver fat on magnetic resonance imaging-
estimated proton density fat fraction (MRI-PDFF) at 6 weeks will be 
analyzed similarly. The secondary preliminary efficacy analysis of the 
proportion of subjects with ≥ 30% relative reduction in liver fat at 
week 12 assessed by MRI-PDFF will be analyzed using a Fisher’s 
exact test.

INTRODUCTION 
4.1 
Background 
Nonalcoholic steatohepatitis (NASH) is a chronic liver disease characterized 
pathologically by steatosis, or lipid accumulation in the liver, with evidence of cellular 
damage, inflammation, and fibrosis [Musso et al. 2016]. Currently, there are no effective 
treatments approved for NASH, which can progress to cirrhosis, hepatitis and ultimately 
hepatocellular carcinoma [Musso et al. 2016]. There are at least 16 million patients in the 
United States (US) and Canada with NASH, which is the second leading cause of liver 
transplants in the US [Sayiner et al. 2016]. NASH presents a significant healthcare 
burden with a high, unmet medical need. Ideally, treatment approaches to NASH would 
target multiple pathogenic axes of the disease, such as steatosis, inflammation and 
fibrosis. 
Accumulating evidence points towards increased hepatic de novo lipogenesis (DNL) as a 
key mediator in NASH pathophysiology. Uncontrolled DNL is a key contributor for liver 
steatosis through excessive triglyceride (TG) synthesis and deposition [Postic et al. 
2008]. Chronic activation of hepatic DNL and increase in the traffic of free fatty acids 
within hepatocytes can lead to generation of toxic lipid metabolites.  These lipotoxic 
metabolites act as reactive oxygen species (ROS), triggering endoplasmic reticulum (ER) 
stress, apoptosis and necrosis in the liver resident cells, hepatocytes, Kupffer cells and 
hepatic stellate cells (HSC) [Peverill al. 2014]. 
An emerging target for a multi-modal mechanism to treat NASH is fatty acid synthase 
(FASN), a key enzyme in the DNL pathway. FASN catalyzes the final step of DNL, 
converting acetyl-CoA and malonyl-CoA to the fatty acid palmitate, which can then 
undergo further modifications to other fatty acids and TGs [Kusakabe et al. 2000]. FASN 
gene expression level is aberrantly elevated in NASH patients as compared to healthy 
volunteers [Dorn et al. 2010; Mitsuyoshi et al. 2009]. Therefore, elevated FASN activity 
may be a major contributor to NASH through lipotoxicity-mediated tissue injury and cell 
death. Liver-specific ablation of the gene encoding FASN in mice (FASNLKO mice) 
results in malonyl-CoA increases and palmitate decreases in liver [Dentin et al. 2006]. 
FASNLKO mice on a standard diet show normal liver TG content, suggesting DNL may 
be dispensable in healthy liver and FASN inhibition may evade negative impact on non-
diseased liver function [Chakravarthy et al. 2005]. 
In addition to FASN’s role in steatosis and lipotoxicity, it may contribute to inflammation 
and the processes of fibrosis [Dorn et al. 2010]. Palmitate, the end product of the fatty 
acid synthesis pathway, upregulates toll-like receptor 4 (TLR4), pro-inflammatory 
cytokines and tumor necrosis factor-α (TNF-α) production in primary hepatocytes and 
Kupffer cells [Sawada et al. 2014]. DNL also generates the fatty acids necessary for T-
Helper 17 (Th17) cell differentiation and function [Berod et al. 2014]. Recent studies 
strengthen the hypotheses regarding the role of Th17 cells and interleukin-17 (IL-17) in 
NASH progression since increased levels of Th17 cells in human liver are associated

with the progression from non-alcoholic fatty liver disease (NAFLD) to NASH [Nati et 
al. 2016; Rau et al. 2016; Tan et al. 2013; Tang et al. 2011]. IL-17 also promotes liver 
fibrosis in a mouse model of liver disease (carbon tetrachloride [CCl4]–induced liver 
injury model) through HSC activation and subsequent collagen production [Meng et al. 
2012; Tan et al. 2013]. Stimulation of HSC activation occurs both by elevation of IL-17 
and by palmitate in mice [Harley et al. 2014; Xu et al. 2013; Tan et al. 2013]. Therefore, 
modulation of FASN offers a promising approach to treating NASH. 
FT-4101 is a potent, selective, orally bioavailable, small-molecule inhibitor of FASN, 
able to potently inhibit DNL and thus influence steatosis, being developed by FORMA 
Therapeutics Inc. and is intended as a treatment for patients with NASH. The clinical 
hypothesis is that FASN inhibition will reduce the rate of DNL, thereby reducing lipid 
accumulation in the liver responsible for the cellular damage, inflammation, and fibrosis 
that characterizes the pathology of NASH. 
4.2 
Rationale for the Proposed Study 
Inhibition of fractional DNL can be measured through use of stable isotopically labeled 
tracers in studies of metabolic kinetics [Hellerstein et al.1991; Lemieux et al. 1999] 
Metabolic infusion studies with sodium acetate (1-13C1) have been utilized to describe a 
temporal pattern of DNL in the postprandial state of healthy subjects and NAFLD 
patients. [Timlin and Parks 2005; Donnelly et al. 2005] More recently, deuterated (heavy) 
water (2H2O) labeling studies have demonstrated that in the non-stimulated setting, 
hepatic DNL is elevated in NASH patients compared to healthy controls [Lawitz et al. 
2018]. 
GS-0976, an inhibitor of ACC1/2, (enzymes upstream of FASN in the DNL pathway), 
has demonstrated a significant (60-70%) inhibition of DNL in healthy obese adult 
volunteers after a single dose or when administered chronically. [Westlin et al. 2016; 
Kirby et al. 2017]. However, a reduced level of DNL inhibition (~30%) was observed 
when an equivalent dose of GS-0976 was administered chronically to NASH subjects 
[Lawitz et al. 2018]. The almost > 2-fold difference in DNL inhibition (67-70% 
inhibition in HV vs ~30% inhibition in NASH) would indicate that a higher and/or a 
more sustained rate of DNL inhibition may be required in the treatment of NASH.  
This study will provide an opportunity to evaluate a dose range of FT-4101 that inhibited 
DNL in an obese, otherwise healthy adult population in a defined NASH patient 
population (defined as metabolically and cardiovascular stable) with further developed 
translational biomarker strategy for monitoring FASN inhibition, and extended safety 
assessment in this population. Clinical development of FT-4101 in a larger population of 
patients with NASH can then occur once FT-4101 has demonstrated acceptable safety 
and clinical activity in this defined NASH population.

Summary of Pre-Clinical /Clinical Studies 
The preclinical in vivo studies have shown adverse effects in the skin and eye, that were 
reversible upon dose de-escalation and interruption. The exposure of FT-4101, necessary 
to demonstrate FASN inhibition in experimental models is below the NOAEL exposure 
in rats, the more sensitive species evaluated. Additional preclinical information is found 
in the Investigator’s Brochure (IB) version 5.0. 
To date, three clinical studies have enrolled subjects and are completed/clinically 
completed. As 01-May-2019, a total of 123 healthy volunteers have received FT-4101 in 
these studies, including 59 subjects with single doses, 10 subjects with two doses, 19 
subjects with multiple doses for up to 14 days, and 35 subjects with multiple doses for up 
to 28 days. A brief summary of each study is provided below; additional information is 
found in the IB version 5.0. 
FT-4101 has been evaluated in humans in a First-in-Human clinical study (Protocol No. 
4101-HVS-101) entitled “A randomized, placebo-controlled, double-blind, single 
ascending and multiple ascending dose study to assess the safety, pharmacokinetics and 
pharmacodynamics of FT-4101 in healthy adult volunteers”. This initial Phase 1 clinical 
study was a single center, double-blind dose escalation study of FT-4101 in healthy adult 
volunteers. FT-4101 was first administered as a single dose in single ascending dose 
(SAD) cohorts, and then administered daily for 14-28 days in multiple ascending dose 
(MAD) cohorts. The preliminary safety profile from this study demonstrated that 9 mg 
daily for 14 days continuously was tolerable while a dose of 27 mg daily for 14 days was 
not tolerated (due to AE’s, including dry eye and skin and alopecia). The safety profile of 
3 mg of FT-4101 administered daily for up to 4 weeks continuously was tolerable and per 
protocol criteria were met for consideration of additional dose escalation in healthy 
volunteers. The pharmacokinetic (PK) and pharmacodynamic (PD) profile from a daily 
dose of 3 mg FT-4101 indicated an exposure that was sufficient for sustained FASN 
inhibition in healthy obese volunteers based on accumulation of plasma malonyl carnitine 
and a 50% reduction in sebum palmitate. 
Higher daily doses of 4.5 mg and 6.0 mg of FT-4101 for up to 4 weeks continuously were 
then evaluated in clinical study FT-4101-CP-001 entitled “A phase 1, double-blind, 
randomized, placebo-controlled, multiple-dose study to assess the safety, 
pharmacokinetics, and pharmacodynamics of FT-4101 in obese but otherwise healthy 
adult subjects”. The preliminary safety profile of both the 4.5 mg and 6.0 mg dose of FT-
4101 administered daily for up to 4 weeks continuously was considered tolerable per 
protocol. However, 44% (4 of 9) subjects receiving 6 mg FT-4101 daily for 4 weeks 
reported grade 1 adverse events of dry skin and alopecia by the end of the 4-week dosing 
interval (all recovered in follow-up), suggesting continuous dosing of 6 mg FT-4101 
beyond 4-weeks would not be tolerable. One subject (11%) in the 4.5 mg treatment group 
reported a grade 1 adverse event of dry skin after 2-weeks of dosing, treated topically, 
and did not worsen with continued dosing. No AE’s of alopecia were reported in the 4.5 
mg treatment group.

Version 2.0_23-Jul-2019 
The Clinical Study 4101-HVS-102, entitled “A randomized, placebo-controlled, double-
blind, pharmacodynamic study of a single oral dose of FT-4101 in healthy adult subjects” 
was a Phase 1, single center, 3-cohort study designed to characterize the 
pharmacodynamic effect of FT-4101 on FASN by conducting metabolic infusion studies 
using sodium acetate (1-13C1) for the measurement of fractional de novo lipogenesis 
(DNL) inhibition in the liver. A single dose of 3 mg, 6 mg or 9 mg of FT-4101 
administered to 10 subjects resulted sustained inhibition of fractional hepatic DNL of 
24%, 43% and 80% respectively. Based on a 1.6 to 2-fold accumulation, a chronic daily 
dose of 3.0 mg to 4.5 mg of FT-4101 would be predicted to achieve a sustained hepatic 
DNL inhibition rate from > 24% to up 80% over the dosing interval. This predicted range 
of hepatic DNL inhibition is consistent with the initial PD effects of inhibiting hepatic 
DNL (based on malonyl carnitine accumulation) and inhibiting sebum DNL (reduction in 
sebum palmitate/triglycerides) observed to date in the clinical studies. 
4.4 
Rationale for Treatment and Dose 
Based on the safety, PK and PD studies of FT-4101 in healthy adult volunteers, a study to 
confirm the safety and evaluate the PK/PD effects of FT-4101 administered chronically 
over 12 weeks in NASH patients is proposed.  The initial starting dose of 3.0 mg of FT-
4101 administered as intermittent therapy is planned based on the safety profile of this 
dose administered daily for 28 days in healthy obese adult volunteers. To reduce the risk 
for ≥ Grade 2 adverse effects due to chronic non-hepatic DNL inhibition, an empiric 
treatment interruption schedule will be evaluated. Subjects (n=15), will be randomized 
2:1 to receive FT-4101 or placebo for 4 treatment cycles. The duration of each treatment 
cycle is 3 weeks: subjects will receive FT-4101or placebo for 2 weeks followed by 1 
week of no treatment (2-weeks on/1-week off). 
Based on the experience reported by GS-0976, it is possible that NASH patients may 
require a higher level of FASN inhibition to achieve meaningful clinical activity as 
measured by a reduction in liver enzymes, hepatic steatosis by MRI-PDFF and hepatic 
DNL inhibition by deuterated water incorporation. Therefore, if after 6 weeks a 3 mg 
dose of FT-4101 or placebo given for 2-weeks on/1-week off, is found to be tolerable, a 
4.5 mg dose of FT-4101 or placebo given for 2-weeks on/1-week off may be evaluated in 
a second cohort of NASH patients.

STUDY DESIGN AND DESCRIPTION 
6.1 
Study Design 
This is a Phase 1/2, randomized, double-blind, placebo-controlled study evaluating the 
safety, tolerability and preliminary efficacy of an intermittent treatment with 3.0 mg and 
4.5 mg FT-4101 over 12 weeks in overweight/obese subjects with NASH.  
The study will be conducted in up to 2 dosing cohorts, that will overlap. Cohorts will 
enroll 15 subjects each, randomized to FT-4101 or placebo in a ratio of 2:1 (10 on FT-
4101, 5 on placebo) 
Cohort A will assess the administration of a dose of 3.0 mg FT-4101 given for 2 weeks, 
alternating with 1 week of no investigational product (IP), continued for 12 weeks. This 
design leads to 4 dosing cycles (2-week daily IP followed by 1 week of no IP). Each 
cycle (C) will include 21 days (D) (e.g., C1/D1 to C1/D21) 
After 6 weeks, a dose escalation meeting will be held and an advancement to a higher 
dosing cohort will only be approved after the safety data from the ongoing cohort is 
determined to be acceptable. 
If the IP is deemed to be safe after 6 weeks of treatment (2 dosing cycles), an additional 
Cohort B may be added. Cohort B will comprise of up to 4.5 mg FT-4101, administered 
as in Cohort A, which is given for 2 weeks, alternating with a 1 week of no IP for 12 
weeks. 
If dose escalation does not proceed; dose de-escalation may occur in subsequent cohorts 
to a dose of 1.5 mg FT-4101 to further refine the dose or additional cohort may be added 
to evaluate the 3.0 mg dose cohort. The IP will be administered as in cohort A, given for 
2 weeks, alternating with a 1 week of no IP, continued for 12 weeks. 
Safety, tolerability, PK and PD assessments will be performed throughout the study.

6.3 
Rationale for Study Design and Endpoints 
This MAD study will assess the safety and tolerability, PK and preliminary PD of FT-
4101 in overweight/obese subjects with NASH compared to placebo.  
Two (2) cohorts will be assessed in ascending order, but may overlap, to determine the 
response to an intermittent dosing cycle (2 weeks of doing followed by 1 week off 
dosing). 
Randomization is used to avoid bias introduced through an association between study 
drug allocation order and subject characteristics. 
A double-blind design has been chosen to avoid bias and to maintain the blind between 
the administration of the study drug and placebo for subjects and clinical staff. 
The placebo control group will control for changes in percent liver fat that may be caused 
by subjects’ lifestyle and diet changes that may occur over the period of study 
participation. 
Subjects with NASH will participate in the study, as these subjects are an important 
target population for FT-4101. Enrollment criteria will favor the target population. 
Percent liver fat will be determined by MRI-PDFF. 
The proposed PK endpoints are well-established, commonly used parameters to 
characterize pharmacological profiles of drugs.  
This is an exploratory study designed for proof of concept. 
6.4 
Dose Escalation 
Data from at least 12 subjects of Cohort A who have completed 2 of the 4 cycles of 
treatment (2 week on /1 week off) is required for safety review before dose escalation to 
Cohort B, provided no more than one subject had an early discontinuation suspected of 
being related to FT-4101.  The safety and tolerability data will be reviewed and if deemed 
appropriate by the Safety Review Committee (SRC) consisting of the coordinating PI, the 
Sponsor medical monitor and at least 1 additional participating center PI, a dose 
escalation decision to proceed to Cohort B will be made that is based on the reviewed 
data. If there are no safety concerns, the next cohort may start and may partially overlap 
with the previous one. 
The blind of the study will be maintained throughout.

6.5 
Study Discontinuation and Stopping Criteria 
6.5.1 Dose Escalation Stopping Criteria 
Dose escalation may be stopped if one of the following conditions applies: 
•
Death of a subject (AE grade 5 toxicity) in a cohort, at any time, that is considered
related to the IP FT-4101 by the Investigator;
•
Two (2) or more of the subjects in a cohort have experienced a serious adverse
event (SAE) or medically significant adverse events (e.g., common terminology
criteria for adverse events (CTCAE) ≥ grade 3 may be used as a grading scale at
the discretion of Investigator), that is judged by the Investigator to be possibly or
probably related to the IP FT-4101;
•
Two (2) or more subjects in a cohort develop an AE (CTCAE grade ≥ 2 may be
used as a grading scale at the discretion of the Investigator) that persists for more
than 7 days and is considered related to the IP FT-4101 by the Investigator;
•
Two (2) or more FT-4101-treated subjects in a cohort develop an AE (CTCAE
grade ≥ 2) of any duration associated with the skin (including hair) or eye that is
considered to be at least possibly related by the Investigator;
•
Two (2) or more subjects in a cohort develop similar clinically significant
laboratory, significant ECG or vital signs abnormalities, or severe AEs in the
same organ class, indicating dose-limiting intolerance. Dose escalation may
proceed if after review of the data by the coordinating Investigator/medical
monitor and discussion with Sponsor, it is concluded that the events are not
related to the IP FT-4101;
•
It is determined that the limit of safety and/or tolerability of FT-4101 has been
reached. Decision will be made between Sponsor and Medical
Monitor/coordinating Investigator.

6.5.2 Study Advancement after Dose Escalation Stopping Criteria 
After stopping criteria are met, the following may occur: 
•
Dose escalation may be stopped.
•
Dose escalation may continue as originally planned. This is only permissible if
the AE(s) that met stopping criteria is judged, after unblinded review, as not being
related to FT-4101;
•
A lower dose (lower than the dose that met stopping criteria) cohort may be
added.
If the SRC decides on any action other than continuing dose escalation as planned, they 
will communicate to the Unblinded Statistician the subject numbers who they believe 
meet stopping criteria. The Unblinded Statistician will check the treatment assignment of 
that subject; if the subject received placebo then the stopping criteria are not triggered for 
that subject, otherwise the stopping criteria will be triggered. The Unblinded Statistician 
will communicate to the SRC their agreement that the stopping criteria are met after 
review of the treatment assignments, if applicable. If stopping criteria are not met due to 
events of concern occurring in placebo subjects, the Unblinded Statistician will 
communicate that the stopping criteria were not met, and communicate the subject 
numbers, who do not qualify based on receiving placebo. This unblinding will only occur 
in cases where the SRC has identified events potentially meeting stopping criteria, and 
will be limited only to subject numbers, experiencing the events in question. The whole 
cohort will not be unblinded to the SRC. 
6.5.3 Criteria for Early Termination of the Study 
The study will be completed as planned unless one or more of the following criteria are 
satisfied that require temporary suspension or early termination of the study. 
•
New information or other evaluation regarding the safety or efficacy of the study
medication that indicates a change in the known risk/benefit profile for the
compound, such that the risk/benefit is no longer acceptable for subjects participating
in the study.
•
Significant violation of Good Clinical Practice (GCP) that compromises the ability to
achieve the primary study objectives or compromises subject safety.
•
Administrative Reasons, (e.g., Sponsor, an institutional review board (IRB)/
independent ethics committee (IEC), or regulatory authority elects to terminate or
suspend the study or the participation of an investigational site)
If the Sponsor, IRB/IEC, or regulatory authority elects to terminate or suspend the study 
or the participation of an investigational site, a study-specific procedure for early 
termination or suspension will be provided by the Sponsor; the procedure will be 
followed by applicable investigational sites during the course of termination or study 
suspension.

6.5.4 Criteria for Early Termination of Individual Subjects 
Subjects may withdraw their consent to participate in the study at any time. 
If a subject withdraws consent, the date and reason for consent withdrawal should be 
documented. Subjects will be encouraged to remain in the clinic for safety assessments 
until the Investigator deems that it is safe for the subject to be discharged. Subject data 
will be included in the analysis up to the date of the consent withdrawal. 
Criteria: 
•
AE or SAE that requires discontinuation at the discretion of the Investigator
•
Protocol violation or concurrent illness: If protocol violation or concurrent illness
occurs, which, in the clinical judgment of the Investigator or after discussion with the
Sponsor, may invalidate the study by interfering pharmacokinetically or
pharmacodynamically with the investigational products, the subject will be
withdrawn by the Investigator (e.g., lack of compliance with study protocol, or lack
of compliance with IP ingestion, as determined per Investigator)
•
Lost to follow-up. The subject did not return to the clinic and attempts to contact the
subject were unsuccessful. Attempts to contact the subject must be documented.
•
Voluntary withdrawal of consent (mandatory removal from study)
•
Discretion of Investigator (document reason on CRF)
•
Subject becomes pregnant or begins breastfeeding (mandatory)
•
Study discontinuation by Sponsor
Wherever possible, the tests and evaluations, including those listed for the Follow-up 
Visit should be performed for all subjects who discontinue prior to the completion of the 
study. 
In the event the Investigator determines to terminate a subject participation in the Clinical 
Study, the Investigator must notify the Sponsor of such decision and rationale 
immediately in writing. In all cases, the appropriate IRB/IEC and other applicable 
regulatory authorities shall be informed. 
6.6 
Treatment Interruption with Dose Modifications 
If a subject has an adverse event that is judged by the Investigator as related to study drug 
(i.e., assessed as unrelated to the underlying disease, intercurrent illness, or concomitant 
medications), then a treatment interruption with dose modification can be made according 
to the guidelines in Table 6-1 below. Deviations from these guidelines (e.g., drug 
interruption for a Grade 1 AE of skin or eye) may occur if agreed upon by the Principal 
Investigator and Medical Monitor. There should be no attempt to make up doses omitted 
due to toxicity.

For further details please see the Pharmacy Manual. 
8.5 
Dose Regimen 
The first dose of IP and deuterated water will be administered by qualified study staff 
while subjects are under observation in the clinical research unit. Accountability for 
deuterated water and IP will be performed to monitor compliance.  
IP will be administered at t=0, orally with approximately 240 mL of water in the 
morning. Subjects do not need to be in a fasting state. A compliance check for the in-
house dosing (hand and mouth check) will confirm that subjects have swallowed the 
complete dose. Actual time of dosing will be documented in the source documents and 
eCRFs. 
During outpatient periods, subjects will take the IP at home once a day (QD) as instructed 
by study staff during the in-house period. Dosing will be intermittent, with 2 weeks of IP 
treatment and 1 week without any IP. Aim is to dose at approximately the same clock 
time on every dosing day. 
Missed IP doses: Ideally, subjects should not miss more than 25% dosing days (>3 days) 
within 1 cycle. If more IP doses are missed than above, the PI will need to decide, with 
input from the Sponsor Medical Monitor, on whether the subject should be withdrawn 
from the study and replaced. 
Details will be provided in the Operations Manual. 
To maintain the double-blind aspect of the study, the investigational products will be 
prepared by unblinded staff that is not participating in investigational product

8.5.1 Deuterated Water 
Subjects will be instructed to drink 3 bottles of 50 mL of deuterated water (70%) daily on 
C1/D-14 through C1/D-8 and C4/D1 through C4/D7. Subjects will also be instructed to 
take each bottle of 50 mL of deuterated water at least 3 hours apart. 
The first oral dose of deuterated water will be administered in-house in the morning of 
C1/D-14 and C4/D1 after Sebutape® and DNL blood sample collections. Subjects do not 
need to be in a fasting state. A compliance check for the in-house dosing will be 
performed. Actual time of dosing will be documented in the source documents and 
eCRFs. Subjects will then be instructed to continue the administration of deuterated water 
at home. The oral intake should occur at approximately the same time of day ± 3 hours on 
every dosing day. During the outpatient phase, subjects will fill in a log recording their 
daily deuterated water intake. If a dose is missed, it should be considered a “loss” and 
noted in the daily log and will be recorded in the CRF. Subjects must not double up on 
their intake (not take two doses at once). 
If a deuterated water dose is missed, the subject should inform the study team and the 
team should record this information. There is no defined number of missed doses that 
constitutes non-compliance. Missed doses will be reported to the Sponsor Medical 
Monitor. The decision to withdraw a subject from study participation based on missed 
doses of deuterated water may be based on decision of the PI and the Sponsor Medical 
Monitor. If a subject is withdrawn, the subject can be replaced.

brief description should be provided in the deviation, including whether the subject was 
symptomatic (list symptoms) or asymptomatic, and the event accidental or intentional. 
Dosing details should be captured on the Dosing Case Report Form. If the subject takes a 
dose of Study Drug that exceeds protocol specifications and the subject is symptomatic, 
then the symptom(s) should be documented as an AE. 
Should an overdose occur, the Investigator or designee should contact the Sponsor or 
designee within 24 hours of the investigator or qualified designee first becoming aware of 
the overdose. 
8.7 
Randomization and Blinding 
Subjects will be randomized to the treatment according to an interactive web response 
system (IWRS). Randomization numbers will be generated from 
. The IWRS 
will assign the next available randomization number at the time the site randomizes the 
subject, maintaining the 2:1 ratio (2 subjects on FT-4101 to 1 subject on placebo). Only 
authorized unblinded personnel will be able to see which treatment arm is assigned to a 
randomization number. Any replacement subjects will be randomized by IWRS to the 
same treatment arm that was assigned to the subject being replaced. The randomization 
number of the replaced subject will be incremented by 100 (e.g., subject 
 replaced 
with 
 subject 
 replaced with 
). 
8.8 
Breaking of Blinded Code 
The only persons with access to the treatment assignments during clinical conduct will be 
the designated pharmacy personnel who are responsible for the dispensing of study drug, 
the unblinded CRO operations team for investigational product accountability and serious 
adverse event (SAE) reporting, the unblinded statisticians who generate the 
randomization lists, and the bioanalyst for PK/PD samples. In general, the Sponsor 
Medical Monitor will remain blinded to treatment assignment. However, during the 
cohort safety review, if the decision is made to halt dose escalation due to an observed 
adverse event that potentially meets stopping criteria, the Sponsor Medical Monitor may 
be unblinded to that subject’s data to ensure that the subject in question is indeed 
receiving FT-4101 and not placebo. This information will be conveyed via the unblinded 
statistician and will be limited to the subject with the safety issue of concern. 
The code for a subject may be broken in a medical emergency, if knowing the identity of 
the treatment allocation would influence the treatment decision of the subject or if 
demanded by the subject. Unblinding will be done through the Electronic Data Capture 
(EDC), however if this is not available, the unblinded pharmacist at the site will have the 
subject list with treatment assignments, and as such would be able to break the blind in 
case of emergency. Whenever a code is broken, the person breaking the code must record 
the time, date, and reason as well as his/her initials in the source documents. During un-

blinding procedure in case of medical emergency, it should be ensured that no study 
personnel is unblinded to other subjects. Study site personnel and Sponsor personnel 
directly associated with the conduct of the study will not be unblinded. 
If the study site needs to unblind a subject, the sponsor will, if possible, be contacted 
prior to breaking the blind. In all cases, the Study Monitor must be notified within 24 
hours after emergency unblinding. 
All codes (whether broken or not) must be kept throughout the trial period. 
Accountability of all broken or unbroken codes (hard copy or electronic) will be 
performed at or after trial closure and codes will be maintained in the Trial Investigator’s 
File (TIF) at the site.

STUDY PLAN 
9.1 
Study Procedures 
9.1.1 Informed Consent and HIPAA Release 
Written informed consent will be obtained from each subject prior to performing any 
study-specific evaluations. The HIPAA release is embedded in the informed consent 
document. The informed consent document is subject to review and approval by the 
Sponsor and will be approved by a qualified IRB. The IRB-approved document must 
contain, at minimum, the eight basic elements of informed consent set forth in applicable 
law. Only the most recently IRB-approved informed consent document must be used to 
consent prospective study subjects. The Investigator (according to applicable regulatory 
requirements), or a person designated by the Investigator and under the Investigator’s 
responsibility, will fully inform the potential study subject of all pertinent aspects of the 
Clinical Study, including written information given approval/favorable opinion by the 
IRB/IEC.  
Prior to the potential subject’s participation in the Clinical Study, the written informed 
consent form must be signed, name filled in and personally dated by the subject and by 
the person who conducted the informed consent discussion, and by the Investigator. One 
copy of the signed and dated informed consent document will be given to the subject and 
the original retained by the Investigator/site. 
9.1.2 Screening 
Investigators must account for all subjects who sign informed consent forms. The 
Investigator will keep a Subject Screening and Enrollment Log at the investigational site. 
Subjects who have screen failed may be allowed to re-screen once at the discretion of the 
Investigator. A new screening number will be assigned. 
Subjects who meet all of the inclusion criteria and none of the exclusion criteria are eligible 
for this study. If subjects are fasting (only water for ≥ 10 hours), all screening assessments 
may be done on the same day. If subjects are not fasting, they will be invited to return for 
a second screening visit to complete any missing screening procedures (e.g. laboratory 
assessments). 
Subjects will be instructed on influencing factors and restrictions such as grapefruit 
containing food and beverages, star fruit (carambola), pomegranate, Seville orange and 
other food components that may interact with CYP3A4, smoking or medication and 
illness/infection. 
If subjects don’t have a diagnosis of NASH stage 2/3 assessed by liver biopsy performed 
within 24 months, FibroScan® (CAP) will be evaluated instead to identify subjects who are 
likely to have a liver fat content of ≥ 10% at MRI-PDFF. Depending on the outcome/results 
of these values, the subjects will proceed to MRI-PDFF or not. For further details on

Subjects MELD score will be calculated according to the following formula: 
MELD(i) = 0.957 × ln(Cr) + 0.378 × ln(bilirubin) + 1.120 × ln(INR) + 0.643 
Then, round to the tenth decimal place and multiply by 10. For further details see the 
Operations Manual. 
9.1.3 Demographics and Medical History 
Demographic information, medical history and prior medications will be obtained at 
Screening. 
9.1.4 Physical Examination 
The baseline physical examination (PE) will consist of the following body systems: (1) 
eyes; (2) ears, nose, throat, neck, thyroid; (3) cardiovascular system; (4) respiratory 
system; (5) gastrointestinal system, mouth; (6) dermatologic system, including hair; (7) 
extremities; (8) musculoskeletal system; (9) central and peripheral nervous system, (10) 
lymph nodes and (11) testicular examination in male subjects. 
An abbreviated PE will be performed by the Investigator (or a qualified physician at the 
investigational site) at time points indicated in the SOE in section 16.1 for each cohort.  
For abbreviated PEs, the following will be examined and/or measured by the Investigator 
or medically-qualified designee: skin (crust, erosion, ulcer, rash, inflammation, etc); eyes 
(dryness, conjunctivitis, etc); hair (assessment of male pattern baldness using the 
Norwood scale [see Appendix D in section 16.4] or assessment of female pattern hair loss 
using the Savin scale [see Appendix E in section 16.5]); lymph nodes; and respiratory, 
cardiovascular, abdominal (gastrointestinal), and musculoskeletal systems.  
In addition, male subjects will undergo a testicular examination on C1/D-1 and C4/D29. 
A complete physical examination may be performed in case the subjects have symptoms 
or at the discretion of the Investigator. 
9.1.5 Height, Weight, and BMI 
Height (without shoes) will be measured once, during the Screening visit 
Weight (without shoes) will be measured fasting in the morning, with light clothing and 
post void at time points indicated in the SOE in section 16.1. 
BMI (kg/m2) will be calculated from height and weight.

Vital signs will include body temperature (aural), supine blood pressure (after 5 minutes 
resting), respiration rate and pulse rate (after 5 minutes resting). Vital sign measurements 
will be performed at days indicated in the SOE in section 16.1. 
9.1.7 Concomitant Illness and Therapy 
Concomitant therapy is any medication given in addition to the investigational product 
(including over-the-counter medications, herbal medications, and vitamin supplements) 
administered between screening and follow-up.  
Concomitant illness is any significant medical condition or disease that is present at study 
start (signing of informed consent). This includes clinically significant laboratory, ECG, 
or physical examination abnormalities noted at Screening examination. 
Details of all concomitant illnesses and therapies must be recorded at study entry and 
must be recorded on the subject’s CRF. Any changes in concomitant medication must be 
recorded at each visit. If the change influences the subject’s eligibility to continue in the 
study, the Sponsor must be informed. The information collected for each concomitant 
medication includes, at a minimum, start date, stop date or continuing, and indication.  
AEs related to administration of these therapies or procedures must also be documented 
on the appropriate eCRF. 
For prohibited medications, please see Table 7-1 Prohibited Medication. 
9.1.8 Procedures for Clinical Laboratory Samples 
All samples will be collected in accordance with acceptable laboratory procedures. 
Laboratory samples will be taken as described in the SOE in section 16.1. 
Additional samples (e.g., including blood samples, urine samples and all types of tissue 
samples) may be collected and stored for potential future analysis. For details please see

9.1.9 Contraception 
Female subjects of non-childbearing potential 
Female subjects of non-childbearing potential must meet the following criteria: 
a) are either surgically sterile (hysterectomy, bilateral tubal ligation, bilateral
salpingectomy, and/or bilateral oophorectomy) at least 6 months before the Screening
Visit. If females’ sterility is confirmed, no pregnancy testing is required during the study.
The site will make an effort to retrieve medical records to document the sterility,
however, the absence of records will not exclude the subject. In case that medical records
cannot be obtained, serum pregnancy testing will be conducted at Screening, and urine
pregnancy testing will be conducted throughout the study.
b) are post-menopausal, defined as spontaneous amenorrhea for > 12 months at the
Screening Visit. Postmenopausal status will be confirmed through testing of FSH levels

outside the normal range (as specified by responsible lab) at screening for amenorrheic 
female subjects < 55 years of age. 
Female subjects who state they are postmenopausal at the screening visit but have an 
FSH value that does not correspond with a postmenopausal FSH level, may have a serum 
hCG pregnancy test performed on a separate day. If test is negative and the subject agrees 
to be on a highly effective contraceptive method, subject may be enrolled in the study at 
the discretion of the Investigator. 
c) a negative serum pregnancy test before starting study treatment. 
 
Female subjects of child-bearing potential 
Female subjects of child-bearing potential must meet the following criteria: 
a) a negative serum pregnancy test before starting study treatment 
b) must agree to refrain from egg donation or harvest for 90 days after last dose of study 
drugs. 
c) If engaged in heterosexual intercourse must agree to use highly effective methods of 
contraception during intercourse, throughout the study period and for 90 days after the 
last dose of study drugs. 
 
Periodic abstinence (calendar, symptothermal, postovulation methods), withdrawal 
(coitus interruptus), spermicides only, and lactational amenorrhoea method are not 
acceptable methods of contraception.  
 
Acceptable methods of contraception under this protocol are listed below. 
 
Female subjects who are considered of childbearing potential must agree to use a highly 
effective method of contraception, which may include:  
• IUD  
• Abstinence: abstinence can be used, when in line with the preferred and usual 
lifestyle of the subject.  
• If a female subject confirms that her male partner(s) has been confirmed to be 
clinically sterile, this method is acceptable as the only means of contraception.  
• Hormonal implants 
 
Note: Hormonal contraceptives alone are not considered an effective method of birth 
control for female subjects participating in this study. Oral contraceptives can be used in 
combination with a male barrier method.  Furthermore, female condoms in combination 
with male condoms is not an acceptable method.

Childbearing Potential  
For all subjects of childbearing potential, all methods of contraception, including 
abstinence, must be in use from the time of consent through the final study visit, and for 
90 days after the last dose of study drug. Subjects who are not sexually active during the 
Screening Period must agree to the contraceptive requirements if they become sexually 
active with a partner of the opposite sex during the study and for 90 days after the last 
dose of study drug. Unique situations that may not fall within these specifications may be 
discussed with the Medical Monitor on an individual basis.  Female subjects will be 
considered of childbearing potential after the onset of their first menstrual period.  
During the study, regular serum human chorionic gonadotropin (hCG) pregnancy tests 
will be performed for sterilized women, when medical records are not available. In 
addition to a negative serum hCG pregnancy test at Screening, subjects also must have a 
negative urine hCG pregnancy test at outpatient visits and check-in to in-house periods. 
 
Male subjects  
Male subjects must meet the following criteria: 
a) are required to use barrier contraception (condom plus spermicide) during intercourse 
from Screening through study completions and for 90 days after the last dose of study 
drugs. 
b) must refrain from sperm donation from Screening through at least 90 days after the last 
dose of study drugs. 
Male subjects who can father a child must agree to use one highly effective method of 
contraception, which includes:  
• Abstinence: abstinence can be used, when in line with the preferred and usual 
lifestyle of the subject.  
• If a male subject confirms that his female partner(s) is not of childbearing 
potential (i.e., postmenopausal or post-surgical sterilization, as defined under 
child bearing potential) or is using a highly effective method of contraception, this 
is acceptable as the only means of contraception.   
Examples of highly effective methods of contraception for male subjects’ female 
partner(s) include:  
o Hormonal contraceptives in combination with male barrier contraception 
o Hormonal implants 
o Intrauterine device (IUD)  
Male subjects with documented infertility or surgical sterilization (performed at least six 
months before the first dose of study drug) are exempt from the contraception 
requirement.

9.1.10 Pregnancy 
In the event a subject becomes pregnant during the study, she should be withdrawn, and 
the study drug should be immediately discontinued. However, the subject will be 
encouraged to complete the post-treatment follow-up portion of the study to the extent 
that study procedures do not interfere with the pregnancy. 
In addition, any pregnancies in the partner of a male subject during the study or for 90 
days after the last dose should also be recorded.  
If the pregnancy occurs at any time during the study and the 90 days of last dose of active 
study medication, the pregnancy should be reported immediately to the Sponsor, using a 
pregnancy notification form. 
Study subjects will give consent on enrollment that the Investigator will report any 
pregnancy during the study to the Sponsor and that they will be asked to provide 
information about her pregnancy, delivery, and the health of her infant until age one 
month. Payment for all aspects of obstetrical care, child, or related care will be the 
subject’s responsibility.  
All reported pregnancies will be followed up to final outcome, using the pregnancy and 
pregnancy follow-up forms. The outcome, including any premature termination, will be 
reported to the Sponsor. An evaluation after the birth of the child may also be conducted. 
Pregnancy complications must be recorded as adverse event(s). If the infant has a 
congenital anomaly/birth defect this must be reported and followed up as a serious 
adverse event. 
9.1.11 ECG Procedure  
A standard 12-lead ECG will be recorded after 5 minutes in a supine position. 
The Investigator (or designee) will interpret the ECGs by use of an electronic 
measurement using the following categories: within normal limits, abnormal but not 
clinically significant, or abnormal with clinical significance. ECGs are performed 
according to the SOE in section 16.1. The following parameters will be recorded from the 
subject’s ECG trace as calculated by the machine algorithm: heart rate, QT interval, PR 
interval, QRS interval, RR interval, and QTc (corrected) using the Fridericia correction 
(QTcF = QT ÷ cube root of the R-R interval [where R-R is the duration of the entire 
cardiac cycle]). 
When ECGs are to be collected at the same time point as a blood collection, ECGs should 
be collected first to avoid any artificially increased heart rates due to the blood collection. 
In some cases, it may be appropriate to repeat abnormal ECGs. If a machine-read QTc 
value is prolonged, repeat measurements may not be necessary if the Investigator’s 
interpretation determines that the QTc value is in the acceptable range.

9.1.12 Check-in Procedure 
All subjects will check in to the clinic in the morning for the In-house Periods. The 
following will be assessed: 
1. Alcohol breath test.
2. Urine drug screen.
3. Urine pregnancy tests. (The negative result of the urine pregnancy test will allow to
check-in, while the negative test result of the serum pregnancy test must be available
prior to dosing on C1/D1).
4. Any use of disallowed prescription or non-prescription concomitant medications
within the last 24 hours.
5. Any medical condition that could interfere with glucose metabolism, as judged by the
Investigator.
6. Consumption of grapefruit (grapefruit containing food and beverages), star fruit
(carambola), pomegranate, Seville orange and other food components that may
interact with CYP3A4, within 24 hours prior to check-in.
Subjects who fulfill one or more of the stated criteria at check–in, will not be able to 
continue onto the treatment period. The treatment period will be rescheduled. Each 
treatment period may be rescheduled one time. After that, the subject will be excluded 
from the study. Replacement of subjects for all dosing periods may be permitted in order 
to enroll sufficient subjects into the study, only after discussion with Sponsor and 
Investigator. 
9.1.13 Blood Glucose Monitoring by Fingerstick 
Blood glucose might be measured by fingerstick whenever there are signs or symptoms 
of hypoglycemia or hyperglycemia. A confirmation measurement of the blood glucose 
value may be performed by YSI. 
9.1.14 Wash-Out Period 
The wash-out period is optional and only subjects with T2DM on combination therapy 
with metformin and sulfonylurea will have to undergo a wash-out period to discontinue 
the oral drug sulfonylurea (SU) until the end of the study. Medication with metformin 
monotherapy will be continued throughout the entire study on the same stable dose. 
Discontinuation of the SU must start at least 7 days prior to C1/D-14, the start of the 
deuterated water labeling period (starting wash-out at least on C1/D-21). All subjects will 
be instructed to monitor and document their fasting plasma glucose levels daily, using a 
glucometer. The subjects will be instructed on how to use the glucometer. A diary will be 
supplied by the study site. For further details on capturing data and documentation in the 
diary, please see the Operational Manual. They will be frequently (at least twice weekly)

contacted by qualified study site staff in the washout period to review their fasting plasma 
glucose values. If a subject has a confirmed morning fasting plasma glucose level (after 8 
hours of fasting) that is ≥ 240 mg/dL (13.3 mmol/L) and cannot be lowered to < 180 
mg/dL (10.0 mmol/L) in 7 days, verified by a standard laboratory analysis (ie, YSI 
glucose analyzer at the site), this subject will be excluded from further participation in the 
study.  
All subjects with T2DM will be provided with a blood glucose meter with sufficient 
supplies and test strips to monitor blood glucose at home during wash-out, run-in and/or 
outpatient periods. For further details on data capturing and documentation, please see the 
Operational Manual. 
9.1.15 Standardized Meals and Dietary Counseling 
Subjects will be counseled to maintain their normal diet and exercise regimen. They will 
be instructed not to start any new diets, supplements, or exercise programs during the 
study. 
During in-house period(s), subjects will receive standardized meals. The same 
standardized meals will be served on C1/D-1 and C4/D14 to standardize conditions prior 
to the C1/D1 and C4/D15 assessments. These meals will be provided up to 12 hours prior 
to start of scheduled fasting DNL samples on C1/D1 and C4/D15. 
The standardized weight maintaining meals will be provided using estimated BMR× 
activity factor of 1.5 to determine daily caloric intake. Daily calories are individualized to 
within 200 calories of estimated BMR x 1.5.  
9.1.16 Pharmacokinetic Assessments and Schedule 
Blood for PK analysis of the IP will be collected at the time points indicated in the SOE 
in section 16.1 and the PK sampling schedule in section 16.2. One 2.0 mL sample per 
scheduled time point will be collected and split equally to provide plasma for primary PK 
measurements and plasma as a secondary back-up sample. Instructions for sample 
processing and shipment will be provided in the Laboratory Manual. Pre-dose sampling 
will be taken within 15 minutes before dosing. PK blood sampling should be performed 
at the nominal time(s) specified in this clinical protocol. All actual PK sample collection 
times will be recorded in the source documents and CRF. Explanation should be provided 
in the source documents and CRF for missed or mishandled samples. 
Concentrations of FT-4101 in plasma will be measured using a validated liquid 
chromatography tandem mass spectrometry (LC-MS/MS) assay.

Sebutape® tightly adheres to the skin surface. The surface area of one Sebutape® is ~5 
cm2. Further details of the procedure are described within the accompanying Operations 
Manual. 
9.1.17.4 FibroScan® (vibration controlled transient elastography) 
One-dimensional vibration controlled transient elastography (VCTE) assessed by 
FibroScan (EchoSens™, Paris, France) will be used in this study. 
At Screening or within 30 days prior to screening, subjects will be examined with the 
FibroScan to assess the controlled attenuation parameter (CAP) and liver elasticity/liver 
stiffness measurements (LSM). Subjects with FibroScan results obtained within 30 days 
prior to screening don’t need to undergo this procedure at screening. 
Only CAP will be used in order to qualify for the inclusion in the study. An additional 
FibroScan measurement will be performed at week 12.  
For the LSM, the device generates a low-frequency shear wave from a probe applied to 
the subject’s skin between the ribs. The speed of the wave spread is then measured 
between two points within the liver to allow the livers stiffness to be quantified. The 
wave will travel more rapidly through stiff tissue. An examination using the FibroScan 
consists of ten signal acquisitions at a single point; the whole process lasts around 15 
minutes. The results (LSM and CAP) are instantly displayed on a screen.

9.1.17.5 De Novo Lipogenesis (DNL) Assessment 
Steady state contribution of fractional DNL to plasma triglyceride (TG) palmitate 
(representing hepatic DNL) and sebum fatty acids (e.g. palmitate and/or sapienic acid) 
will be determined using mass isotopomer distribution analysis (MIDA). For the 
assessment of fractional hepatic DNL during the study, subjects need to be in fasting 
conditions (no food or drink, except for water for 10 hours prior). Fasting is not required 
for the assessment of sebum DNL. A 2-week deuterated water labeling approach will be 
used to allow fully labeling of newly synthesized fatty acids (DNL) in liver triglycerides 
and sebum. Multiple blood and sebum samples will be collected throughout the 
assessment period for the measurement of deuterium enrichment in fatty acids and body 
water.  
Sampling time points on different days should be at approximately the same clock time. 
For details please see the Operations Manual.

ADVERSE EVENTS 
The investigator or designee and research site staff are responsible for the detection, 
documentation, classification, reporting, and follow-up of events meeting the definition 
of an AE or serious AE (SAE). Procedures for managing AEs and SAEs are detailed in 
the research site’s SOPs.  
Spontaneously reported or observed AEs will be recorded throughout the study beginning 
at the time the subject gives informed consent. AEs will be elicited using a non-leading 
question at designated time points. Regardless of seriousness, intensity, or presumed 
relationship to study drug, all AEs will be recorded in the source documentation from the 
time of first contact with the subject (e.g. Screening) until the end of the follow-up period 
of the study. All measures required for management of AEs will be recorded in the source 
documentation. 
10.1 
Definitions 
10.1.1 Adverse Event (AE) 
An AE is any undesirable and unintended medical event occurring to a subject in a 
clinical study, whether or not related to the study products. This includes events from the 
first study related activity after the subject has signed the informed consent and until post 
treatment follow-up period as defined in the protocol. The following should not be 
recorded as AEs, if recorded as medical history/concomitant illness on the CRF at 
screening: 
•
Pre-planned procedure, unless the condition for which the procedure was planned
has worsened from the first study related activity after the subject has signed the
informed consent
•
Pre-existing conditions found as a result of screening procedures
•
Pre-existing events that has not worsened in intensity or frequency from baseline.
10.1.2 Treatment emergent Adverse Event (TEAE) 
•
A TEAE is defined as any untoward medical occurrence in a subject administered a
medicinal product that does not necessarily have a causal relationship with this
treatment.
•
A TEAE can, therefore, be any unfavorable and unintended sign (including an
abnormal laboratory finding), symptom, or disease temporally associated with the use
of an investigational product, whether or not related to the investigational medicinal
product.
•
This includes an exacerbation of pre-existing conditions or events, intercurrent
illnesses, drug interaction, or the significant worsening of the indication under

Version 2.0_23-Jul-2019 
investigation that is not recorded elsewhere on the eCRF under specific efficacy 
assessments.   
Anticipated fluctuations of pre-existing conditions that do not represent a clinically 
significant exacerbation or worsening are not considered AEs. 
If progression of the underlying disease (i.e., the condition being treated with study drug) 
might be reasonably anticipated given the nature and severity of the underlying disease, 
then progression of the underlying disease per se will not constitute an AE. However, if 
the progression of the underlying disease meets the criterion for “serious” categorization 
of AEs (e.g., the underlying disease results in death or hospitalization, etc.), then the 
progression of underlying disease should be reported as an SAE. 
10.1.3 Serious Adverse Event (SAE) 
An SAE is any untoward medical occurrence that occurs at any dose (or, occurs after 
informed consent is given and prior to dosing) that: 
•
Results in death.  Any event resulting in death during the reporting period [from
signing of ICF through 28 days after last dose of study drug(s)] must be treated as an
SAE and reported as such.
•
Is life-threatening (subject is at immediate risk of death from the event as it occurred)
NOTE: this is different than Life-threatening severity criteria.
•
Requires in-subject hospitalization (formal admission to a hospital for medical
reasons) or prolongation of existing hospitalization
•
Results in persistent or significant disability/incapacity
•
Results in a congenital anomaly/birth defect
Important medical events that may not result in death, are not life-threatening, or do not 
require hospitalization may be considered SAEs when, based on appropriate medical 
judgment, they may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition.  Examples of such 
events include allergic bronchospasm requiring intensive treatment in an emergency 
room or at home or the development of drug dependency or drug abuse. 
The following are not considered SAEs and therefore do not need to be reported as such: 
•
Pre-planned or elective hospitalization including social and/or convenience situations
(e.g., hospitalization due to weather or travel issues)
•
Overdose of either study drug or concomitant medication unless the event meets SAE
criteria (e.g., hospitalization).  However, the event should still be captured as a non-
serious AE on the appropriate eCRF page

10.1.4 Clinical Laboratory Assessments as Adverse Events and Serious Adverse 
Events 
It is the responsibility of the investigator to assess the clinical significance of all 
abnormal values as defined by the list of reference ranges from the local laboratory. In 
some cases, significant changes in lab values within the normal range will require similar 
judgment. 
An abnormal laboratory value that is not already associated with an AE is to be recorded 
as an AE only if any one of the following criteria is met: 
•
an action on the study drug is made as a result of the abnormality
•
intervention for management of the abnormality is required
•
at the discretion of the investigator should the abnormality be deemed clinically
significant
10.2 
Recording of Adverse Events and Serious Adverse Events 
•
Any AE that occurs after signing of ICF through 28 days after last dose of study
drug(s) should be recorded on the AE eCRF.
•
In order to avoid vague, ambiguous, or colloquial expressions, the AE should be
recorded in standard medical terminology rather than the subject’s own words.
•
Whenever possible, the investigator should combine signs and symptoms that
constitute a single disease entity or syndrome into a final diagnosis, if appropriate.
For example, fever, cough, and shortness of breath may be reported as pneumonia, if
that is the final diagnosis.
•
Each AE is to be evaluated for duration, severity, seriousness, and causal relationship
to the investigational drug.  The action taken and the outcome must also be recorded.
•
SAEs that occur during the study or within 28 days after last dose of study drug(s),
whether related to study drug, must be immediately reported to the Sponsor/SAE
designee. Clinical trial sites will enter SAE information directly into the EDC clinical
database within 24 hours of knowledge of the event.  After the 28-day reporting
window, only SAEs assessed as related to study drug need to be reported.
10.3 
Evaluation of Adverse Events and Serious Adverse Events 
The investigator or designee is responsible for making an assessment as to the seriousness, 
intensity, causality, action taken, and outcome of an AE. 
10.3.1 Intensity of AEs 
Intensity refers to the severity of the AE. The Investigator must categorize the severity of 
each AE according to the NCI CTCAE version 5.0. CTCAE guidelines can be referenced

Protocol No. 4101-MET-201 
Version 2.0_23-Jul-2019 
at the following website: 
https://ctep.cancer.gov/protocoldevelopment/electronic_applications/ctc.htm 
For any term that is not specifically listed in the CTCAE scale, intensity will be assigned 
a grade of one through five using the following CTCAE guidelines: 
Grade 1: Mild; asymptomatic or mild symptoms, clinical or diagnostic observations 
only; intervention not indicated 
Grade 2: Moderate; minimal, local or noninvasive intervention indicated; limiting 
age-appropriate instrumental activities of daily living 
Grade 3: Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care 
activities of daily living 
Grade 4: Life-threatening consequences; urgent intervention indicated 
Grade 5: Death related to AE 
10.3.2 Causal Relationship to Study Treatment 
Medical judgment should be used to determine the cause of the AE considering all 
relevant factors such as, but not limited to, the underlying study indication, coexisting 
disease, concomitant medication, relevant history, pattern of the AE, temporal 
relationship to the study medication, dechallenge or rechallenge. 
Not Related or Unlikely to be related 
•
An AE that is clearly due to extraneous causes (e.g., concurrent disease, concomitant
medications, disease under study, etc.)
•
It does not follow a reasonable temporal sequence from administration of study drug
•
It does not follow a known pattern of response to study drug
•
It does not reappear or worsen when study drug is restarted
•
An alternative explanation is likely even if not clearly identifiable
Related, Possibly related, or Probably related 
•
An AE that is difficult to assign to alternative causes
•
It follows a strong or reasonable temporal sequence from administration of study drug
•
It could not be reasonably explained by the subject’s clinical state, concurrent disease,
or other concomitant therapy administered to the subject
•
It follows a known response pattern to study drug
•
It is confirmed with a positive rechallenge or supporting laboratory data

Reporting Procedures 
10.4.1 Any Adverse Event 
Regardless of seriousness, intensity, or presumed relationship to study drug, all AEs will 
be recorded in the source documentation. Whenever possible, diagnoses will be recorded, 
when signs and symptoms are due to a common etiology. In addition, the investigator must 
record his or her opinion as to the intensity of the AE and whether the AE is related to study 
drug. All measures required for management of the AE will be recorded in the source 
documentation. 
10.4.2 Serious Adverse Events and Suspected Unexpected Serious Adverse Serious 
Reactions (SUSARs) 
All SAEs, regardless of relationship to study drug, must be reported to the Sponsor/SAE 
designee within 24 hours of knowledge of the event, according to the procedures below.  
It is important that the investigator provide an assessment of relationship of the SAE to 
study treatment at the time of the initial report. Clinical trial sites will enter SAE 
information directly into the EDC clinical database within 24 hours of knowledge of the 
event.

Protocol No. 4101-MET-201 
 
Version 2.0_23-Jul-2019 
The Sponsor or its designee is responsible for submitting reports of AEs associated with 
the use of the drug that are both serious and unexpected to the U.S. Food and Drug 
Administration (FDA), according to 21 Code of Federal Regulations (CFR) 312.32; and 
to other applicable regulatory authorities, according to national law and/or local 
regulations. 
All investigators participating in ongoing clinical studies with the study medication will 
receive copies of these reports for prompt submission to their Institutional Review Board 
(IRB) or Independent Ethics Committee (IEC).  In accordance with the European 
Commission Clinical Trials Directive (2001/20/EC), the Sponsor or its designee will 
notify the relevant ethics committees in concerned member states of applicable suspected 
unexpected serious adverse reactions as individual notifications or through periodic line 
listings. 
The Sponsor or its designee will submit all safety updates and periodic reports to the 
regulatory authorities as required by applicable regulatory requirements (i.e., within 7 
days for treatment related unexpected fatal or life-threatening events; within 15 days for 
all other treatment related unexpected serious events).   
10.4.3 Pregnancy or Drug Exposure during Pregnancy 
• If a subject becomes pregnant during the study the investigator is to stop dosing with 
study drug(s) immediately. 
• A pregnancy is not considered to be an AE or SAE; however, it must be reported to 
the Sponsor using the Pregnancy Report Form within the same timelines as an SAE. 
This applies to a female subject or the female partner of a male subject (note: 
additional consent may be required to obtain information from the female partner). 
• The pregnancy should be followed through to outcome, whenever possible.  Once the 
outcome of the pregnancy is known, the Pregnancy Outcome Reporting Form should 
be completed and reported to the Sponsor. 
• AEs or SAEs that occur during pregnancy will be assessed and processed according 
to the AE or SAE processes using the appropriate AE or SAE forms.

DATA HANDLING AND MANAGEMENT 
Clinical Data Management (CDM) is the responsibility of 
 Chula Vista, USA. 
11.1 
Data Management 
The full details of procedures for data handling will be documented in the Data 
Management Plan (DMP). 
AEs and medical history will be coded using the current version of the Medical 
Dictionary for Regulatory Activities (MedDRA). Concomitant medications will be coded 
using the World Health Organization (WHO) WHO Drug Global dictionary. The 
MedDRA version used will be recorded in the Study Master File documentation. 
Unique numbers will identify the subject and the biological material obtained from the 
subject. Appropriate measures such as encryption or deletion will be enforced to protect 
the identity of human subjects in all presentations and publications as required by 
local/regional/national requirements. 
Data from screening failures will be entered into the database. The data for screen 
failures will be limited to ICF date, demographics, and eligibility assessment including 
reason(s) for screen fail.  
Laboratory data from the central laboratory will be electronically transferred to 
 for database reconciliation purposes and loading into EDC for data review 
purposes. In cases where sensitive non-PK laboratory data is transferred via non-secure 
electronic networks, data will be encrypted during transfer. 
The laboratory will provide one copy of the laboratory reports to the site staff. The site 
staff will receive all laboratory data electronically or based on FAX reports directly from 
the laboratory. An Investigator must review, evaluate, sign and date the laboratory print-
outs upon receipt. The signed print-out of the laboratory reports are source data. 
All other results, including PK, PD data, and laboratory tests will be transferred 
electronically to the responsible Data Management Unit. 
11.2 
CRFs (Electronic) 
11.2.1 Clinical Data Management Workflow 
Electronic CRFs will be developed by the CDM, in collaboration with the clinical study 
team and statistician. CDM will document the process workflow in the DMP. After data 
entry, monitor(s) will source data verify (SDV) the eCRFs against the source documents. 
Queries may be issued to clarify the data entered. The PI will electronically sign the 
eCRFs after all data have been entered, source data verified, and all queries have been 
resolved. If corrections and/or resolution of queries are required after PI approvals, those 
eCRFs affected by changes will be re-signed by the PI. The database may be locked after 
the PI approvals are completed and the Sponsor has reviewed the data and authorized 
lock.

After database lock, CDM study design documentation and locked eCRFs (PDF) will be 
created and will be provided to the Sponsor. 
11.2.2 Data Entry of eCRFs 
Data required for analyses and subject safety assessments will be entered from source 
documentation into eCRFs. Instructions for data entry will be provided in the eCRF 
Completion Guidelines, developed by 
 CDM department. All site staff 
involved with entering data into the eCRFs will be trained prior to gaining access to the 
study database. 
11.2.3 Corrections to eCRFs 
Queries may be generated by the eCRF system during data entry, and queries may be 
generated by CDM staff, monitors, PIs, the Sponsor, and other data reviewers during the 
course of the study. Only specific site personnel will be authorized to make corrections to 
the eCRFs; CDM will train personnel prior to granting access in the eCRF system. 
Corrections will be made directly in the eCRF – by modifying existing data, adding new 
data, or deleting data, as appropriate. All data corrections will be logged in the electronic 
audit trail. 
11.2.4 PI Approval of eCRF Data 
The Investigator or Investigator’s authorized staff must ensure that all information 
derived from source documentation is consistent with the source information and 
accurately reflected in the eCRFs. By electronically signing the eCRFs, the Investigator 
confirms that the information is complete and correct. 
11.3 
Retention of Documents 
At the completion of the study, all records created by and under the supervision of the 
Investigator should be maintained in accordance with the requirements of the regulatory 
authority guideline and the GCP Guideline. These will be available for inspection at any 
time by the Sponsor or the FDA. 
Clinical study documents are archived upon completion of the study and maintained for 
at least 15 years from the study closure or longer in accordance with local regulation and 
applicable regulatory authority guidelines, and the study sponsor will be notified prior to 
destruction of study records. 
Current FDA guidelines require records to be retained for a period of 2 years following 
the date a marketing application is approved for the drug, for the indication for which it is 
being investigated. If no application is filed or if the application for the investigated 
indication is not approved, documents will be kept until 2 years after the investigation is 
discontinued and the FDA is notified. It is the sponsor’s responsibility to inform 
 as to when essential documents are no longer needed to be retained

Analysis Sets 
12.2.1 Safety Set 
The Safety set will include all subjects who received IP (FT-4101 or Placebo) or 
deuterated water. The Safety set will be used for demographic, baseline characteristics 
and safety summaries. 
12.2.2 Pharmacokinetic (PK) Set 
The PK set will include all subjects who received FT-4101 or placebo with sufficient 
evaluable PK concentration data appropriate for the evaluation of interest (without major 
protocol deviations or violations that would have an impact on the absorption, 
distribution, metabolism, or excretion). The PK set will be used for analysis of PK 
endpoints. 
12.2.3 Preliminary Efficacy Set 
The Preliminary Efficacy set will include all subjects who received FT-4101 or placebo 
with at least one quantifiable baseline and one post baseline MRI-PDFF (without major 
protocol deviations or violations that would have an impact on the PD). The Preliminary 
Efficacy set will be used for analysis of MRI-PDFF endpoints. 
12.2.1 Pharmacodynamic (PD) Set 
The PD set will include all subjects who received FT-4101 or placebo without major 
protocol deviations or violations that would have an impact on PD.  The PD set will be 
used for analysis of PD endpoints. 
12.3 
Analysis of Demographics and Other Baseline Characteristics 
Demographic and baseline characteristics will be summarized for all subjects overall and 
by cohort and treatment. Summary statistics (e.g., number of subjects, mean, median, 
standard deviation, and range) will be generated for continuous variables (e.g., age and

Version 2.0_23-Jul-2019 
Change at Week 12 (absolute and relative) in percentage of liver fat as assessed by MRI-
PDFF will be analyzed by a Wilcoxon rank-sum test.  The test will be one-sided and use 
a significance level of 0.05.  Subjects in each dose group will be tested against the pooled 
placebo subjects from each cohort. 
If more than one dose of FT-4101 is evaluated, control of the alpha level will be 
accomplished using Holm’s Sequential Bonferroni procedure [Holm 1979] to test each 
FT-4101 dose against the pooled placebo subjects. 
12.5.2 Analysis of Secondary Preliminary Efficacy and Pharmacodynamic 
Endpoints 
The following are secondary preliminary efficacy endpoints: 
•
Reduction (absolute and relative) of % liver fat on magnetic resonance imaging-
estimated proton density fat fraction (MRI-PDFF) at 6 weeks
12.5.2.1 Liver Fat Assessed by MRI-PDFF 
Reduction of % liver fat on MRI-PDFF at 6 weeks will be analyzed similarly as the 
primary preliminary efficacy endpoint. 
In addition, a mixed effects model with repeated measures (MMRM) will be used to 
analyze the change from baseline, both absolute change and percent change (absolute and 
relative), to week 6 and week 12; the model will include baseline as a covariate and the 
factors, treatment group, visit, and the interaction of treatment group and visit. The least 
squares (LS) mean and its corresponding 95% confidence interval and p-value will be 
presented. The LS mean difference between treatment groups will be presented along 
with the 95% confidence interval and the p-value. 
12.5.2.2 Proportion of Subjects with ≥ 30% Relative Reduction in Liver Fat at Week 12 
Assessed by MRI-PDFF 
The proportion of subjects experiencing a relative reduction of 30% or greater of liver fat 
at week 12 as assessed by MRI-PDFF will be summarized descriptively and analyzed 
using a Fisher’s exact test. Subjects in each dose group will be tested against the pooled 
placebo subjects from each cohort. 
12.5.2.3 Liver Biochemistry Markers 
The following are secondary pharmacodynamic liver biochemistry marker endpoints: 
•
Alanine aminotransferase (ALT)
•
Aspartate aminotransferase (AST)
•
Gamma-glutamyl transferase (γGT)
•
Alkaline phosphatase
•
Total bilirubin

The observed values and the change from baseline of the liver biochemistry markers 
above be analyzed descriptively by treatment group and visit. 
A MMRM will be used to analyze the change from baseline to C3/D1, C4/D15, and 
C4/D22; the model will include baseline as a covariate and the factors, treatment group, 
visit and the interaction between treatment group and visit. The least squares (LS) mean 
and its corresponding 95% confidence interval and p-value will be presented for each 
postbaseline visit. The LS mean difference between treatments will be presented along 
with the 95% confidence interval and the p-value for each postbaseline visit. 
12.5.3 Analysis of Exploratory Pharmacodynamic Endpoints 
In general, exploratory analysis will be descriptive, unless specified otherwise in the 
SAP. 
The observed value and the change from baseline of the exploratory endpoint parameters 
will be analysed descriptively by treatment group and visit. 
Fasting Hepatic DNL may be analysed using a statistical model. 
12.5.3.1 Fasting Hepatic De Novo Lipogenesis 
The following is the exploratory pharmacodynamic endpoint related to fasting hepatic de 
novo lipogenesis: 
• Inhibition of fasting hepatic de novo lipogenesis (DNL) after administration of 
multiple doses in overweight/obese subjects with NASH by using a 2-week 
deuterated water labeling protocol 
The derivation of the fasting hepatic DNL and the inhibition of hepatic DNL will be 
discussed in detail in the SAP.  
The observed values and the change from baseline of fasting hepatic DNL and hepatic 
DNL inhibition (%) will be analyzed descriptively by treatment group and visit. 
Inhibition of hepatic DNL over time will be analyzed graphically. 
A MMRM, similar to the MMRM described previously, may be used to analyze the 
change from baseline of fasting hepatic DNL and hepatic DNL inhibition. 
12.6 
Analysis and Endpoints 
12.6.1 Analysis of Primary Safety and Tolerability Endpoints 
To assess safety and tolerability of FT-4101 after administration of multiple doses in 
overweight/obese subjects with NASH by: 
• Incidence of treatment-emergent adverse events (TEAEs) 
• Incidence of clinical lab abnormalities 
• Incidence and severity of clinical findings on physical examination

•
Change from baseline in vital signs (blood pressure [BP], heart rate [HR],
respiratory rate, and temperature])
•
Change from baseline in 12-lead electrocardiogram (ECG) parameters
Safety and tolerability of the study drugs will be assessed by collection and review of 
adverse events, tolerability, laboratory parameters, physical examination, vital signs, and 
ECG parameters throughout the duration of the study. Safety analysis will involve 
examination of the descriptive statistics and individual subject listings for any effects of 
study treatment on clinical tolerability and safety. 
AEs will be summarized using the safety set. 
All AEs will be coded using MedDRA. Data will be summarized using preferred term 
and primary system organ class. 
Adverse event summaries will include the overall incidence (by system organ class and 
preferred term), events by maximum intensity, event by relationship to study treatment, 
events leading to discontinuation of study drug, and serious adverse events. Physical 
exam, vital signs, ECG, and laboratory parameters (hematology, chemistry, and 
urinalysis) will be summarized descriptively by treatment group. 
12.7 
Interim Analysis 
No interim analysis is planned. 
12.8 
Determination of Sample Size 
With 10 evaluable subjects in the treated group and 10 evaluable subjects in the control 
group, there is 84% power to detect a difference of 20% between the high dose treated 
group and the pooled placebo subjects in cohorts A and B in MRI-PDFF, assuming a 
standard deviation of 14% using a one-sided Wilcoxon-Mann-Whitney test with an alpha 
of 0.05. 
The total sample size will be 30 subjects, 15 subjects per cohort randomized 2:1 to 
receive FT-4101 or placebo.

aCycle (C) 1 Day (D) 1 (C1/D1) is the start of the four 21-day treatment cycles.  Study visits occurring before C1/D1 are based on a countdown to this date. 
Subsequent study visits are defined by the days from the start of the most recent treatment cycle.  
bStudy windows are not provided on these study dates. C1/D1 is the start of study treatment. C1/D-1 must occur on the day prior to C1/D1.  C4/D14 and 
C4/D15 visits are required to occur starting on the last day of study treatment in cycle 4 (C4/D14), in order to obtain time and treatment day-dependent PK/PD 
samples. 
cDay 1 of treatment cycles 2-4 expected to start 22 days (±1) from start of previous treatment cycle (except when dose delays required for AE’s-see protocol).

dIn subjects who discontinue study participation before completion of the study treatment period in Cycle 4, the end of treatment (EOT) visit (C4/D22) should 
occur approximately ≥6 days from last dose of FT-4202/placebo. 
eIn subjects who discontinue study participation before completion of the study treatment period in Cycle 4, a follow-up visit occurring approximately 28 days 
from the start of the last treatment cycle (Day1) is requested. 
fDrug is administered QD on days 1-14 and held days 15-21 of each treatment cycle. Hold dose of IP in the morning of visits occurring during the active 
treatment period until all fasting visit procedures have been completed and as instructed per visit.
gInterim medical history 
hEach bottle of deuterated water should be consumed at least 3 hours apart 
iSubjects will be instructed to fast (no food or drink, except water) on the evening prior to the visit to ensure an approximate 10-hour fast prior to the fasted 
blood sample collection the next morning. Blood for DNL needs to be taken prior to consumption of deuterated water on C1/D-14, C1/D-11, C4/D1, and 
C4/D4. Blood samples for DNL are taken pre-dose on days IP is administered also. 
jIncludes blood for deuterium enrichment in palmitate and body water.  Samples should be collected same time of day. 
kPK sampling will follow Appendix B (PK sampling schedule) in section 16.2. 
lSampling for fasting circulating biomarker include metabolic parameter (FPG, fasting insulin, HOMA-IR, HbA1c, Adiponectin (total and high molecular 
weight), FGF-21, and Malonyl carnitine), liver injury and fibrosis biomarkers (CK-18 fragment, ELF score [HA, PIIINP, TIMP-1], PRO-C3). 
mTo be performed within a window of 4 days prior to C3/D1 and C4/D22 
nThese Sebutape samples collected at D-14 will be stored for potential future fatty acid analysis. 
oThis FibroScan can be performed at screening or within 30 days prior to screening. Both LSM and CAP values are captured and recorded. Both LSM and CAP 
are PD endpoints but only CAP (≥300dB/m) is part of the eligibility criteria.

Appendix C - CYP3A Strong Inhibitors and Inducers 
Examples of strong clinical inhibitors for P450-mediated metabolism 
Strong inhibitors 
CYP3A 
boceprevir, cobicistat(a), conivaptan(a), danoprevir and ritonavir(b), 
elvitegravir and ritonavir(b), grapefruit juice(c,e), indinavir and 
ritonavir(b), itraconazole(a), ketoconazole, lopinavir and ritonavir(a,b), 
paritaprevir and ritonavir and (ombitasvir and/or dasabuvir)(b), 
posaconazole, ritonavir(a,b), saquinavir and ritonavir(a,b), telaprevir(c), 
tipranavir and ritonavir(c,d), troleandomycin, voriconazole 
clarithromycin(c), diltiazem(c), idelalisib, nefazodone, nelfinavir(c), 
cannabidiol (CBD) oil(f) 
Note: Strong, moderate, and weak inhibitors are drugs that increase the AUC of sensitive index substrates 
of a given metabolic pathway ≥5-fold, ≥2 to <5-fold, and ≥1.25 to <2-fold, respectively. Strong inhibitors 
of CYP3A causing ≥10-fold increase in AUC of sensitive index substrate(s) are shown above the dashed 
line. 
(a) Strong inhibitor of CYP1A2 and CYP2C19, and moderate inhibitor of CYP2D6 and CYP3A.
(b) Strong inhibitor of CYP2C19 and moderate inhibitor of CYP2C9 and CYP3A.
(c) Inhibitor of P-gp (defined as those increasing AUC of digoxin to ≥1.25-fold).
(d) Ritonavir is usually given in combination with other anti-HIV or anti-HCV drugs in clinical practice.
Caution should be used when extrapolating the observed effect of ritonavir alone to the effect of
combination regimens on CYP3A activities.
(e) The effect of grapefruit juice varies widely among brands and is concentration-, dose-, and preparation-
dependent. Studies have shown that it can be classified as a “strong CYP3A inhibitor” when a certain
preparation was used (e.g., high dose, double strength) or as a “moderate CYP3A inhibitor” when another
preparation was used (e.g., low dose, single strength).

John’s wort(e) 
Note: Strong, moderate, and weak inducers are drugs that decreases the AUC of sensitive index substrates 
of a given metabolic pathway by ≥80%, ≥50% to <80%, and ≥20% to <50%, respectively. 
(a) Strong inducer of CYP3A and moderate inducer of CYP1A2, CYP2C19.
(b) Strong inducer of CYP2C19, CYP3A, and moderate inducer of CYP1A2, CYP2B6, CYP2C8, CYP2C9.

Appendix D - Norwood’s Classification of Hair Loss 
Type I: 
There is minimal or no recession of the hairline. 
Type II: 
There are triangular, usually symmetrical, areas of recession at the frontotemporal 
hairline. 
Variant IIA: 
The hairline is anterior to the coronal plane 2 cm anterior to the external auditory 
meatus. 
Type III: 
This represents the minimal extent of hair loss, sufficient to be considered as baldness 
according to Norwood. There are deep symmetrical recessions at the temples that are 
bare or only sparsely covered by hair. In Type III vertex, the hair loss is primarily from 
the vertex with limited recession of the frontotemporal hairline that does not exceed the 
degree of recession seen in Type III. 
Variant IIIA: 
The hairline has receded back to a point between the limit of Type IIA and the level of 
the external auditory meatus.

Protocol No. 4101-MET-201 
Version 2.0_23-Jul-2019 
Type IV: 
The frontotemporal recession is more severe than in Type III and there is sparse hair or 
no hair on the vertex. The two areas of hair loss are separated by a band of moderately 
dense hair that extends across the top. This band connects with the fully haired fringe on 
the sides of the scalp. 
Variant IVA: 
The hairline has receded beyond the external auditory meatus but has not reached the 
vertex. 
Type V: 
The vertex hair loss region is still separated from the frontotemporal region, but it is less 
distinct. The band of hair across the crown is narrower and sparser and the vertex and 
frontotemporal regions of hair loss are bigger. 
Variant VA: 
The area of denudation includes the vertex. Hair loss more severe than Type VA cannot 
be distinguished from Types VI or VII. 
Type VI: 
The bridge of hair that crosses the crown is gone with only sparse hair remaining. The 
frontotemporal and vertex regions are joined together, and the extent of hair loss is 
greater. 
Type VII: 
The most severe form of hair loss and only a narrow band of hair in a horseshoe shape 
remains on the sides and back of the scalp. This hair is usually not dense and may be 
quite fine.
