Summary of changes to version 5.0 
Underline indicates the addition and strikethrough indicates the deletion in this summary. 
Administrative changes: Minor changes involving grammar, wordsmithing, punctuation, and 
other editorial changes have been made throughout the document and are not detailed in this 
summary.  
Overall rationale for changes in the protocol: 
This study includes a main study and a sub-study. Up to 40 patients were expected to be 
included in this sub-study (i.e. up to 10 patients per treatment group). Due to unexpected 
recruitment difficulties, only 14 patients were randomized in the sub-study. In addition, the sub-
study site activities have been restricted due to the COVID-19 pandemic which made the sub-
study assessments even more complex if not impossible. The number of evaluable patients 
would have been very low and the decision was made by POXEL to discontinue the sub-study. 
Ongoing patients will continue the study visits and perform the assessments planned in the main 
study but will not performed the assessments planned in the sub-study at End-of-treatment Visit 
(V7). As a consequence, the sub-study objectives will be considered as exploratory. 
Other changes include the addition of key secondary endpoints and minor editorial and 
typographical updates.

1. Synopsis (Trial Objectives): edits 
Secondary Exploratory objectives for Sub-study only: 
• To assess the effect of PXL770 versus placebo in NAFLD patients on metabolic and non-
metabolic parameters at the daily dose of 250 md QD and BID and 500 mg QD after 12 
weeks of treatment: 
- 
Fructose stimulated hepatic De Novo Lipogenesis (DNL)  
- 
Glycemic parameters during a 3-hour oral glucose tolerance test (OGTT)  
 
The two tests being combined, OGTT will be a 3-hour glucose + fructose tolerance 
test (OGTT+F) 
• To assess PXL770 plasma concentrations before, during and after the 3-hour OGTT+F 
and fructose stimulated hepatic DNL assessment in NAFLD patients and correlation with 
pharmacodynamics and/or safety

• Screened Analysis Set: all patients who were screened for inclusion into the study  
• Run-in Safety Analysis Set (RISS): all patients having received at least one dose of 
the single-blind placebo run-in treatment. 
• Safety Set (SS): all randomized patients having received at least one dose of the IMP 
(either PXL770 or placebo) and considered as-treated. Primary set for safety analyses 
and tolerability will be analyzed on the Safety Set. 
• Randomized Set (RS): all patients randomized and considered as randomized 
regardless of the treatment actually received. 
• Intention-to-treat Set (ITTS): all patients having received at least one dose of the IMP 
(either PXL770 or placebo) and considered as randomized.   Primary set for efficacy 
analyses. 
• Per Protocol Set (PPS): ITT patients without any major violations. 
• Pharmacokinetic (PK) population: all patients from the SS who have been treated with 
PXL770 according to the protocol and have provided at least one pre-dose PK 
assessment during the study with sufficient plasma to derive the Cpre. 
Efficacy analyses 
Primary Endpoint:  
The primary endpoint, i.e. expressed as the relative change in the percentage of liver fat mass 
(assessed by MRI-PDFF) from baseline (Randomization Visit (V3)) to Week 12 (V7), will be 
analyzed in an analysis of covariance (ANCOVA) model adjusting for treatment (PXL770 doses 
of 250 mg QD, 250 mg BID and 500 mg QD and placebo) and for stratification factors, i.e. 
T2DM status (T2DM patients versus non-T2DM patients) and study site (main site 1 vs main 
site 2 vs main site 3 vs others) and baseline liver fat mass as a covariate. Least square means 
(LSMs) of the primary endpoint for treatment groups and pairwise differences in LSMs will be 
estimated along with their unadjusted p-values and 95% confidence intervals.  
Missing MRI-PDFF at Week 12 (V7) will be estimated using a multiple imputation method 
assuming missing at random (MAR) mechanism that will be detailed in the SAP. Missing 
baseline MRI-PDFF will not be estimated. 
[…] 
Key secondary Endpoints:  
• Absolute change in the percentage of liver fat mass from baseline (Randomization Visit 
(V3)) to Week 12 (V7): this will be analyzed in an analysis of covariance (ANCOVA) 
model adjusting for treatment, T2DM status (T2DM patients versus non-T2DM 
patients), site (main 1 vs main 2 vs main 3 vs others) and baseline liver fat mass. Least 
square means of the change in the percentage of liver fat mass for treatment groups 
(PXL770 doses of 250 mg QD, 250 mg BID and 500 mg QD and placebo) and pairwise 
differences in LSMs will be estimated along with their unadjusted p-values and 95% 
confidence intervals. 
• Responders (as defined in the Assessment for Efficacy Section): Response will be 
defined for a patient when the (absolute) reduction in liver fat mass (from baseline 
(Randomization Visit (V3)) to Week 12 (V7)) is higher than or equal to 5% (≥ 5 %). 
The response will be analyzed in a logistic regression model adjusting for treatment 
(PXL770 doses of 250 mg QD, 250 mg BID and 500 mg QD and placebo), T2DM status 
(T2DM patients versus non-T2DM patients), site (main 1 vs main 2 vs main 3 vs others) 
and baseline liver fat mass.  Pairwise differences in treatment groups will be estimated 
in this model as odds ratios along with their p-values and 95% confidence intervals.

To detect and monitor a possible DILI, the following evaluations should be performed in the 
presence of significant elevations of liver indices. 
[…] 
• Close observation for suspected drug-induced liver injury includes the following:  
- 
Repeating liver enzyme (ALT, AST, and ALP) and TBL tests 2 or 3 times weekly. The 
frequency of repeat testing can decrease to once a week or less if abnormalities 
stabilize or the study drug has been discontinued and the patient is asymptomatic. 
- 
Obtaining a more detailed history of symptoms and prior or concurrent diseases.

- 
Obtaining a history of concomitant drug use (including nonprescription medications 
and herbal and dietary supplement preparations), alcohol use, recreational drug use, 
and special diets. 
- 
Ruling out acute viral hepatitis types A, B, C, D, and E; autoimmune or alcoholic 
hepatitis; hypoxic/ischemic hepatopathy; and biliary tract disease. 
- 
Obtaining a history of exposure to environmental chemical agents. 
- 
Obtaining additional tests to evaluate liver function, as appropriate (e.g. INR, direct 
bilirubin, lactate, liver ultrasound). 
- 
Considering gastroenterology or hepatology consultations. 
If a DILI is confirmed or suspected by the Investigator, or in case of liver function 
parameters (ALT, AST, ALT, TBL) above the threshold defined in this section, the 
Investigator will complete an Expedited Liver Assessment Report page form (ELAR) in 
the eCRF within 24 hours of knowledge of the case and submit it to Medpace Clinical 
Safety in the same timelines as a SAE (see Section 8.3.6.4 Procedure for Reporting 
Immediately Reportable Events (IREs= SAEs and Pregnancy)). If the DILI is 
confirmed, it should be reported in addition as an AE (see Section 8.3.6.2 Methods of 
Recording and Assessing Adverse Events). 
 
9.4.2 Safety analyses and Safety Set: addition 
The Run-in Safety Analysis Set (RISS) is defined as all patients having received at least one 
dose of the single-blind placebo run-in treatment.  The population will be used to assess 
exposure and compliance with the single-blind placebo run-in treatment only. 
The Safety Analysis Set (SS) comprises all randomized patients having received at least one 
dose of the study drug (either PXL770 or placebo) and considered as-treated. Safety and 
tolerability will be analyzed on the safety set. 
  
9.4.4 PK Population: edits 
The PK population corresponds to the Safety Set and includes all randomized patients who have 
been treated with PXL770 according to the protocol and have provided at least one pre-dose 
PK assessment during the study with sufficient plasma to derive the Cpre. 
 
9.5.1 Primary Endpoint: relative change in the percentage of liver fat mass: edits 
The primary analysis of efficacy will be performed on the ITTS. 
Primary analysis: 
The primary endpoint, i.e. expressed as the relative change in the percentage of liver fat mass 
(assessed by MRI-PDFF) from baseline (Randomization Visit (V3)) to Week 12 (V7), will be 
analyzed in an analysis of covariance (ANCOVA) model adjusting for treatment (PXL770 doses 
of 250 mg QD, 250 mg BID and 500 mg QD and placebo) and for stratification factors, i.e. 
T2DM status (T2DM patients versus non-T2DM patients) and study site (main site 1 vs main 
site 2 vs main site 3 vs other pooled sites) and baseline liver fat mass as a covariate.

Least square means (LSMs) of the primary endpoint for treatment groups and pairwise 
differences in LSMs will be estimated along with their unadjusted p-values and 95% confidence 
intervals.  
Missing MRI-PDFF at Week 12 (V7) will be estimated using a multiple imputation method 
(fully conditional specification method) assuming missing at random (MAR) mechanism 
which will be detailed in the SAP. Missing baseline MRI-PDFF will not be estimated. 
Validity of the ANCOVA model will be checked (studentized residuals will be plotted against 
predicted values, etc.).   
 
9.5.2.1 
Absolute Change in the percentage of liver fat mass: edits   
The (absolute) change in the percentage of liver fat mass (assessed by MRI-PDFF) from 
baseline (Randomization Visit (V3)) to Week 12 (V7) will be analyzed in an analysis of 
covariance (ANCOVA) model adjusting for treatment, T2DM status (T2DM patients versus 
non-T2DM patients), site (main 1 vs main 2 vs main 3 vs others) and baseline liver fat mass. 
Least square means of the change in the percentage of liver fat mass for treatment groups 
(PXL770 doses of 250 mg QD, 250 mg BID and 500 mg QD and placebo) and pairwise 
differences in LSMs will be estimated along with their unadjusted p-values and 95% confidence 
intervals.  
Missing MRI-PDFF at Week 12 (V7) will be estimated using a multiple imputation method 
(fully conditional specification method) assuming missing at random (MAR) mechanism 
which will be detailed in the SAP. Missing baseline MRI-PDFF will not be estimated. 
Validity of the ANCOVA model will be checked (studentized residuals will be plotted against 
predicted values, etc.).  
The same sensitivity analyses proposed for the primary endpoint will be performed.  
 
9.5.2.2 Analysis of responders: edits    
Four types of responders will be proposed and analyzed: 
- 
Response will be defined for a patient when the as an (absolute) reduction in liver fat 
mass (from baseline (Randomization Visit (V3)) to Week 12 (V7)) is higher than or 
equal to 5% (≥ 5 %). 
- 
Response defined as a relative reduction in liver fat mass (from baseline 
(Randomization Visit (V3)) to Week 12 (V7)) higher than or equal to 30% (≥ 30 %). 
- 
Response defined as a relative reduction in liver fat mass (from baseline 
(Randomization Visit (V3)) to Week 12 (V7)) higher than or equal to 50% (≥ 50 %). 
-  
Response defined as a liver fat mass value at Week 12 (V7)) that is normalized, i.e. 
lower than or equal to 5% (≤ 5 %). 
Percentages of response will be estimated within each treatment group. 
The response will be analyzed in a logistic regression model adjusting for treatment (PXL770 
doses of 250 mg QD, 250 mg BID and 500 mg QD and placebo), T2DM status (T2DM patients 
versus non-T2DM patients), site (main 1 vs main 2 vs main 3 vs others) and baseline liver fat 
mass.  Pairwise differences in treatment groups will be estimated in this model as odds ratios 
along with their p-values and 95% confidence intervals.

Exploratory objectives for Sub-study only: 
• To assess the effect of PXL770 versus placebo in NAFLD 
patients on metabolic and non-metabolic parameters at the 
daily dose of 250 md QD and BID and 500 mg QD after 12 
weeks of treatment: 
- 
Fructose stimulated hepatic De Novo Lipogenesis 
(DNL)  
- 
Glycemic parameters during a 3-hour oral glucose 
tolerance test (OGTT)  
 
The two tests being combined, OGTT will be a 3-hour 
glucose + fructose tolerance test (OGTT+F) 
• 
To assess PXL770 plasma concentrations before, during 
and after the 3-hour OGTT+F and fructose stimulated 
hepatic DNL assessment in NAFLD patients and 
correlation with pharmacodynamics and/or safety 
Trial Design and Plan 
(Design description in Figure 1 
and schedule of visits in Table 1) 
Phase IIa, multi-center, double-blind, placebo-controlled, 
randomized study with 4 parallel groups in NAFLD patients. 
There will be a total of 4 study periods, as follows: 
• Screening period: maximum of 2 weeks 
• Single-blind placebo Run-in period: 4 weeks  
• Double-blind treatment period: 12 weeks  
• Follow-up period: 1 week  
Patients will be randomized in a 1:1:1:1 ratio to receive either: 
• PXL770 250 mg QD 
• PXL770 250 mg BID 
• PXL770 500 mg QD 
• Placebo 
Randomization will be stratified according to type 2 diabetes 
mellitus (T2DM) status (T2DM patients versus non-T2DM 
patients) and study site (main study site 1 vs main study site 2 vs 
main study site 3 vs other study sites).  
A sub-study will be performed in up to 3 study sites. This sub-
study will include: 
- 
A fructose stimulated hepatic DNL assessment  
- 
A 3-hour OGTT+F 
Planned Number of Patients 
120 patients to be randomized in order to obtain at least 96 
evaluable patients (24 patients per treatment group) accounting 
for a 20% drop-out rate. Among the 120 randomized patients, up 
to 40 patients will be included in the sub-study (i.e. up to 10 
patients per treatment group).

post-hoc genetic and pharmacogenetic research on the 
DNA/RNA samples from patients who sign an optional, 
additional informed consent.  
The frozen samples will be stored centrally, and will be 
destroyed within 2 years after clinical study report finalization. 
Statistical Methods 
Sample size calculation 
Sample size determination is based on the primary endpoint, i.e. 
the relative percent change in liver fat mass (assessed by MRI-
PDFF) from baseline (Randomization Visit (V3) to Week 12 
(V7). 
Assuming an expected difference of 30% between at least one 
dose of  PXL770 and placebo, a common standard deviation of 
30% (estimated from previous published data [1]), a two-sided 
significance level of 0.05, 24 patients per treatment group are 
required to achieve a power of 90%. Given the early stage of 
development (i.e. a Phase II trial for internal decision), no 
adjustment for comparison multiplicity will be considered. 
The sample size is expanded to 30 patients per group to account 
for an expected 20% drop-out rate, which amounts to a total 
required number of 120 patients to be randomized. 
Statistical methods 
Full details of analyses will be provided in the Statistical 
Analysis Plan (SAP), which will be finalized prior to the 
unblinding and locking of the database. 
Analyses sets 
• Screened Analysis Set: all patients who were screened 
for inclusion into the study  
• Run-in Safety Analysis Set (RISS): all patients having 
received at least one dose of the single-blind placebo run-
in treatment. 
• Safety Set (SS): all randomized patients having received 
at least one dose of the IMP (either PXL770 or placebo) 
and considered as-treated. Primary set for safety analyses 
and tolerability will be analyzed on the Safety Set.

• Randomized Set (RS): all patients randomized and 
considered as randomized regardless of the treatment 
actually received. 
• Intention-to-treat Set (ITTS): all patients having received 
at least one dose of the IMP (either PXL770 or placebo) 
and considered as randomized.   Primary set for efficacy 
analyses. 
• Per Protocol Set (PPS): ITT patients without any major 
violations. 
• Pharmacokinetic (PK) population: all patients from the 
SS who have been treated with PXL770 according to the 
protocol and have provided at least one pre-dose PK 
assessment during the study. 
Efficacy analyses 
Primary Endpoint:  
The primary endpoint, i.e. expressed as the relative change in 
the percentage of liver fat mass (assessed by MRI-PDFF) from 
baseline (Randomization Visit (V3)) to Week 12 (V7), will be 
analyzed in an analysis of covariance (ANCOVA) model 
adjusting for treatment (PXL770 doses of 250 mg QD, 250 mg 
BID and 500 mg QD and placebo) and for stratification factors, 
i.e. T2DM status (T2DM patients versus non-T2DM patients) 
and study site (main site 1 vs main site 2 vs main site 3 vs 
others) and baseline liver fat mass as a covariate. Least square 
means (LSMs) of the primary endpoint for treatment groups 
and pairwise differences in LSMs will be estimated along with 
their p-values and 95% confidence intervals.  
Missing MRI-PDFF at Week 12 (V7) will be estimated using a 
multiple imputation method assuming missing at random 
(MAR) mechanism that will be detailed in the SAP. Missing 
baseline MRI-PDFF will not be estimated 
Sensitivity analyses will be performed based on a rank analysis.  
Subgroup analyses will be performed: 
- within each T2DM status (T2DM patients versus non-T2DM 
patients). The treatment by T2DM status interaction will be 
tested.  
- within each site (main site 1 vs main site 2 vs main site 3 vs 
other pooled sites). The treatment by site (main 1 vs main 2 vs 
main 3 vs others) interaction will be tested.  
Key secondary Endpoints:  
• Absolute change in the percentage of liver fat mass from 
baseline (Randomization Visit (V3)) to Week 12 (V7): 
this will be analyzed in an analysis of covariance 
(ANCOVA) model adjusting for treatment, T2DM status 
(T2DM patients versus non-T2DM patients), site (main 
1 vs main 2 vs main 3 vs others) and baseline liver fat 
mass. Least square means of the change in the percentage

of liver fat mass for treatment groups (PXL770 doses of 
250 mg QD, 250 mg BID and 500 mg QD and placebo) 
and pairwise differences in LSMs will be estimated 
along with their p-values and 95% confidence intervals. 
• Responders (as defined in the Assessment for Efficacy 
Section) will be analyzed in a logistic regression model 
adjusting for treatment (PXL770 doses of 250 mg QD, 
250 mg BID and 500 mg QD and placebo), T2DM status 
(T2DM patients versus non-T2DM patients), site (main 
1 vs main 2 vs main 3 vs others) and baseline liver fat 
mass.  Pairwise differences in treatment groups will be 
estimated in this model as odds ratios along with their p-
values and 95% confidence intervals.  
Methods handling missing MRI-PDFF at Week 12 (V7) 
and therefore the responder status at Week 12 (V7) will 
be detailed in the SAP. 
Other secondary Endpoints:  
The analysis of these secondary endpoints will be fully detailed 
in the SAP.   
Safety Endpoints:  
Safety endpoints will be analyzed with usual descriptive 
methods. 
PK Endpoints:  
Pharmacokinetic data (PXL770 concentrations) will be analyzed 
using a Population PK model. PK parameters will be listed and 
summarized by treatment groups and by visits/timepoints.

2 Background Information 
2.1 Scientific Rationale 
Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease associated with fat 
accumulation in the liver exceeding 5% in people with no or little alcohol consumption [2]. The 
development of non-alcoholic steatohepatitis (NASH) is the result of both environmental 
(sedentary lifestyle and excessive calorie intake) and individual predispositions, which lead to 
adipose tissue expansion, insulin resistance, liver fat accumulation (steatosis or non-alcoholic fatty 
liver - NAFL) with potentially development of inflammation and fibrosis (NASH). The ultimate 
stage of cirrhosis contributes to hepatic impairment and development of hepato-carcinoma. 
NAFLD has shown a rapid increase in prevalence worldwide (25% in the global population) and 
is particularly important in subjects with obesity, metabolic syndrome and T2DM reaching 70% to 
90% in these high-risk populations [3]. It is estimated that around 1.8 billion individuals have 
NAFLD worldwide [4].  Up to now, the best therapeutic approach for NAFLD consists in diet and 
exercise. This approach has proven an efficacy evidenced by improvement of liver biopsy [5]. 
However, these important lifestyle modifications are difficult to achieve and to sustain for the wide 
majority of the population [6]. Although the initial description was published in 1980 [7], its full 
spectrum and impact as a major chronic liver disease have only been recognized for the past 2 
decades [8]. To date, no pharmacological agent has proven a clinically meaningful benefit/risk 
profile as potential drug for NAFLD, and, to date, no drug has been recognized as standard 
pharmacotherapy and approved in this indication. Hence, there is an unmet medical need for 
pharmacological agents for management of NAFLD patients. 
The pathogenesis of NALFD is primarily driven by the progressive expansion of the adipose tissue 
secondary to poor lifestyle, triggering a low-grade inflammation state responsible for insulin 
resistance. Insulin resistance enhances fatty acids (FAs) release from the adipose tissue (lipolysis) 
towards the liver, FAs synthesis from carbohydrate in the liver (DNL), both promoting unexpected 
FAs accumulation in the liver (steatosis). Steatosis can stay uncomplicated for decades, but in a 
subset of subjects, inflammatory processes will develop leading to hepatocellular injuries and 
promoting fibrosis (steatohepatitis).  
5' adenosine monophosphate-activated protein kinase (AMPK) is an energy sensor that regulates 
cellular metabolism in multiple peripheral tissues (liver, adipose tissue, muscle, pancreatic  
cells…). When activated under low energy condition, AMPK stimulates catabolic pathways to 
produce energy (glucose uptake and lipid oxidation) while turning off energy consuming processes 
(gluconeogenesis and FA synthesis), in order to restore energy balance. In addition or in parallel 
to its metabolic effect, AMPK activation has been shown to have anti-inflammatory effects, 
improving the cellular functional environment. It is already well-established that AMPK activation 
by pharmacological compounds (metformin, thiazolidinediones), adipokines (leptin, adiponectin)

or physical activity causes many beneficial metabolic changes in subjects with metabolic syndrome. 
New drugs that directly activate AMPK are expected to improve both glucose and lipid homeostasis 
and may bring a substantial improvement in the treatment of NAFLD.  
PXL770 is a new chemical entity from a new class of drug. It is a direct AMPK activator and is 
currently under development in the treatment of NAFLD.  
2.2 PXL770 
2.2.1 Non-clinical Information 
PXL770 activates AMPK isoforms both allosterically and by protecting the enzyme from its 
dephosphorylation.  PXL770 binding involves 1 and 2 subunits.  PXL770 activates most of all 
12 AMPK complexes with a higher potency for 1 isoforms.  It triggers downstream AMPK 
signaling, including acetyl-CoA carboxylase (ACC) inhibition and peroxisome proliferator-
activated receptor gamma coactivator 1-alpha (PGC-1α) activation in the liver, as well as hormone-
sensitive lipase (HSL) inhibition in adipose tissue. PXL770 was shown in vitro to induce inhibition 
in hepatic gluconeogenesis, to increase muscle glucose uptake, and to decrease hepatic lipogenesis 
both in mouse and human hepatocytes. 
In various in vivo rodent models of diabetes, PXL770 (25, 50, 75, 100 and 150 mg/kg BID orally) 
was shown to significantly decrease HbA1c and basal glycemia, to improve oral glucose tolerance 
with a concomitant decrease in insulin secretion suggesting a potential insulin sensitizing effect, 
and to delay the onset of diabetes.  A significant benefit in lipid profile was also observed with a 
significant decrease in plasma triglycerides and FFA.  PXL770 was shown also to improve liver 
steatosis.  
In a mouse model of NASH, PXL770 treatment increased AMPK phosphorylation, reduced liver 
weight, reduced liver triglyceride levels, reduced liver inflammation, and reduced markers of liver 
damage (including ALT and AST).  PXL770 also improved the overall NAFLD Activity Score, 
which is the sum of an individual’s scores for steatosis, inflammation, and ballooning. 
A decrease in body weight during first days of treatment was only observed in some obese mouse 
models associated with a decrease in food intake.  During these first days of treatment 
gastrointestinal (GI) events (diarrhea) were also observed in some specific obese mouse models.  
PXL770 administration with progressive dose escalation prevented the GI adverse reaction while 
still inducing a sustained decrease in food intake and in body weight. PXL770 administered orally 
was tested up to 1000 mg/kg/day in the rat and was well-tolerated in the 4-week study while in the 
13-week toxicity study, one satellite female rat in the 1000 mg/kg/day group died prematurely 
following clinical signs (hypothermia and decreased activity). At the doses of 400 and 1000 mg/kg, 
some gastrointestinal symptoms were observed, mainly diarrhea, hypersalivation and abdominal

distension, with a dose-dependent increase in the incidence and severity of the symptoms. The no-
observed-adverse-effect-level (NOAEL) was considered to be 400 mg/kg/day in rat. In dog 
PXL770 was tested up to 300 mg/kg/day. In the 13-week toxicity study, instances of severe liquid 
feces occurred that were considered adverse at doses of 300 mg/kg/day, but were completely and 
rapidly reversible. No treatment-related changes in cardiac function were observed during the 
13-week dosing period, as shown by telemetry and absence of glycogen accumulation in the heart. 
The NOAEL was considered to be 150 mg/kg/day in dog. 
PXL770 did not show any evidence of genotoxicity and no specific findings were reported during 
the safety pharmacology studies.  
2.2.2 Clinical Information 
The development of PXL770 started in Europe, and the following studies were conducted: 
• A first-in-human, single ascending dose (SAD), phase I study (PXL770-001) to evaluate 
the safety, tolerability and pharmacokinetic profile of single doses of PXL770 ranging from 
30 mg up to 500 mg and to assess the food effect in Caucasian healthy male subjects. 
• A multiple ascending dose (MAD), phase I study (PXL770-002) to evaluate the safety, 
tolerability and pharmacokinetic profile of multiple doses of PXL770 ranging from 60 mg 
up to 500 mg for 10 days and to assess the drug-drug interaction with rosuvastatin in 
Caucasian healthy male subjects. 
2.2.2.1 PXL770-001: SAD phase I study 
In this study, the safety and tolerability profile of PXL770 doses up to 500 mg were very good. The 
only treatment-emergent adverse event (TEAE) considered possibly related to PXL770 was mild 
dizziness and occurred in the 250 mg treatment group.  
After a single oral dose of 30 mg to 500 mg, PXL770 is rapidly absorbed and distributed, and is 
eliminated according to a multi-exponential decay with a first elimination phase from 8h to 24h 
and a terminal elimination phase after 24h with an estimated terminal half-life ranging from 19h to 
30h (enterohepatic cycle).  PXL770 is metabolized by the liver and is not eliminated in urine. The 
median time to reach the maximum concentration (Tmax) is 1.5-2.5 hours across all doses.  Plasma 
exposures increase approximately linearly and dose proportionally.  PXL770 maximum 
concentration (Cmax) and exposure decrease in presence of food by around 60%.    Dose escalation 
was stopped after a single dose of 500 mg as the corresponding PXL770 AUCinf exceeded the 
defined AUC PK cap (corresponding to plasma exposure observed in dog after 4 weeks of repeated 
administration at the NOAEL dose (100 mg/kg/day)) by around 11%. The maximum tolerated dose 
(MTD) was not reached. A food effect was also investigated at the dose of 250 mg. There was a 
decrease in the Cmax (57% of fasting state) and in the exposure AUC0-24h (67% of the fasting state) 
of PXL770 observed after a high fat breakfast compared to the values observed in fasting condition.

2.2.2.2 PXL770-002: MAD phase I study 
In this study, the safety and tolerability profile of PXL770 doses up to 500 mg were good.  There 
were no Serious Adverse Events (SAEs), nor premature discontinuation. Related TEAE were 
reported in 17% of subjects receiving the placebo and in 36% of the subjects receiving PXL770 
without clear dose dependency. All AEs were of mild or moderate intensity.  They were mainly 
from the gastrointestinal system (transient abdominal pain or discomfort) or from the central 
nervous system (headache). All TEAEs were resolved at the end of the study. During the drug-drug 
interaction assessment with rosuvastatin, only one TEAE (headache) was considered as related in 
the rosuvastatin alone group. 
PXL770 was rapidly absorbed and distributed. The elimination was multi-phasic with a slow 
terminal phase. The median Tmax was 1.5-3 hours across all doses.  Plasma exposures (Cmax and 
AUCinf) were approximately linear and dose proportional up to 375 mg and tended to saturate 
between 375 mg and 500 mg. Steady-state was reached after 6 days of treatment. The highest mean 
PXL770 Cmax and AUCinf were observed at the 375 mg dose and represented approximately 40% 
and 67% of their respective tox-covers. There was no relevant accumulation for Cmax but a slight 
accumulation for exposure was observed (slightly exceeded one (up to 1.88 after QD regimen (60 
mg) and 1.96 at a BID regimen) after 10 days of treatment. The PK was shown to be time invariant. 
Inter-interindividual variability of the PK parameters was overall moderate. Urinary excretion of 
PXL770 after repeated oral administration was almost null. There was no clinically relevant drug-
drug interaction between PXL770 and rosuvastatin. 
A concentration-response model between QTcF and PXL770 concentrations was developed to 
describe the relationship between changes from baseline in QTcF (∆QTcF) and PXL770 plasma 
concentrations. 
Predicted ∆∆QTcF calculated for each dose level were always negative due to a shift in intercept 
for PXL770 treated subject compared to placebo. Indeed, the subjects receiving PXL770 had a 
difference of -3.2 msec in intercept compared to placebo subjects. However, this difference was 
not significant (p=0.4928) and did not suggest any model misspecification. The 90% CI upper were 
all below the regulatory threshold of 10 msec allowing to conclude that PXL770 is unlikely to 
induce QT/QTc prolongation.

safety of PXL770, please refer to the latest version of the Investigator's Brochure (IB) for

4 Study Design 
4.1 Study Design and Schedule 
This study is a phase IIa, multi-center, double-blind, placebo-controlled, randomized study with 4 
parallel groups in NAFLD patients. 
There will be a total of 4 study periods, as follows: 
• Screening period: maximum of 2 weeks 
• Single-blind placebo Run-in period: 4 weeks  
• Double-blind treatment period: 12 weeks  
• Follow-up period: 1 week  
Patients will be randomized in a 1:1:1:1 ratio to receive either: 
• PXL770 250 mg QD 
• PXL700 250 mg BID 
• PXL770 500 mg QD 
• Placebo 
Randomization will be stratified according to T2DM status (T2DM patients versus non-T2DM 
patients) and study site (main study site 1 vs main study site 2 vs main study site 3 vs other study 
sites).  
The study site stratification “Main study site # (1 to 3)” refers to sites of the sub-study only. 
A sub-study will be performed in up to 3 study sites. This sub-study will include: 
- 
A fructose stimulated hepatic DNL assessment 
- 
A 3-hour OGTT+F 
The diagram of the study design is shown in Figure 1 and the visit schedule is tabulated in Table 
1 and in Figure 2.  
The duration of study for each patient from the first visit for the informed consent signature (ICF) 
up to the end of the Follow-up period will be between 17 and 19 weeks.  
The End-of-study is defined as the date of last visit of last patient participating in the study.  
4.2 Rationale for Study Design, Doses and Control Group 
This study is a phase IIa, multi-center, double-blind, placebo-controlled, randomized, parallel-
group study in NAFLD patients to assess the efficacy, safety and tolerability of PXL770 
administered as monotherapy, following International Conference on Harmonization (ICH) E6 
Good Clinical Practice (GCP).

The Single-blind placebo Run-in period is set to reduce any bias regarding placebo effect, to assess 
patient compliance and to minimize the possible confounding influence of dietary and activity 
changes. The 12-week Double-blind treatment duration period is selected based on the 
pharmacological data observed in the rodent NASH model. This duration is supported by the 13-
week toxicological studies in rats and dogs.  The Follow-up period is set to examine the reversibility 
of potential AE after taking the last dose of IMP. 
The dose selection was based on the estimated dose range of efficacy established during the 
pharmacological program and the PK, safety and tolerability observed in healthy subjects during 
the SAD/MAD phase I studies. The study has been designed to investigate the effects of two daily 
doses (250 mg or 500 mg) and two regimens (QD or BID).  As a matter of fact, the Cmax and AUCinf 
were approximately linear and dose proportional from 60 mg up to 375 mg but they both tended to 
saturate between 375 mg and 500 mg (highest dose tested in the MAD phase I study but not the 
MTD). As mentioned previously, the food affects both the Cmax and the exposure of the drug (57% 
and 67% of the fasting values, respectively). The active dose range is expected to be 165 mg to 350 
mg QD based on the effects observed during the pharmacological studies in several animal models 
of NASH and T2DM. Considering the good tolerability of the drug in phase I and the food effect, 
the doses of 500 mg and 250 mg have been selected for evaluation in this proof of concept study, 
250 mg being in the lower part of the expected active dose  range  and 500 mg QD at the higher 
end of the active dose range. The once daily regimen is expected to be the appropriate regimen 
based on the relatively long half-life of the compound. However, it is not fully determined whether 
the effects of PXL770 are mainly driven by the Cmax or by the exposure as the half-life is shorter 
in the rodents and most of the studies have been conducted with a twice daily regimen. So, it 
appeared also critical to investigate the activity of the top dose (500 mg per day) administered as a 
twice daily regimen.   
A sub-study will be performed in up to 3 study sites. This will be a mechanistic study performed 
in T2DM or non T2DM population. It is expected to include up to 10 patients per treatment group 
for a total of up to 40 patients.

5.4.2 Patients Incorrectly Randomized 
If a patient who does not meet the Inclusion/Exclusion criteria mistakenly enters the Double-blind 
treatment period, a discussion should occur between the POXEL Medical Representative, the 
Medpace Medical Monitor and the Investigator regarding whether to continue or discontinue the 
IMP, based on patient’s safety and study’s consideration. In situations where an agreement cannot 
be reached, the patient should be withdrawn from the study. In such case, patients will be 
considered as withdrawn from the study due to protocol deviation. 
5.5 Criteria for Screen-failure 
Patients who are withdrawn from the study between the Screening Visit (V1) and the 
Randomization Visit (V3) will be considered as screen failure.

The reason for screen failure must be documented in source documents and reported in the 
electronic Case Report Form (eCRF) and interactive web response system (IWRS). If more than 
one reason is given, the Investigator should make all efforts to establish the main reason. 
Patients should return at study site to bring back the remaining IMP Run-in kits, the patient diary 
dispensed and the SMBG device, if applicable. The Investigator will perform the IMP 
accountability; verify the patient diary, AE and concomitant medications and SMBG measurements 
if applicable. The SMBG device will be kept by the patient after the end of his/her study 
participation if applicable. This information will be recorded in the patient file and in the eCRF.

Patients will then be referred to their physician for the pursuit of routine medical care. 
5.6 Criteria for Withdrawal from the Study for Randomized Patients during 
the Double-blind Treatment Period 
5.6.1 Criteria for withdrawal from the study 
Patients may withdraw from the study at any time at their own request.  
The Investigator must temporarily interrupt or permanently discontinue the IMP if 
continued administration of the IMP is believed to be detrimental to the patient well-being. 
IMP should be discontinued and the patient should be withdrawn from the study in the event 
of any of the following: 
1. Occurrence of an AE or SAE which is clinically relevant and affects patient’s safety, if 
discontinuation of the IMP is considered necessary by the Investigator or POXEL Medical 
Representative  
2. Occurrence of DILI (as defined in Section 8.3.8.2 DILI) 
3. Occurrence of pregnancy 
4. Important protocol deviation if discontinuation of IMP is considered necessary by the 
Investigator or POXEL Medical Representative/designee 
5. Intake of non-permitted drug (as defined in Section 6.5 Non-permitted Medicines) if 
discontinuation of IMP is considered necessary by the Investigator or POXEL Medical 
Representative/designee 
6. Requirement of an emergency unblinding (as described in Section 6.3.3.2 Emergency 
Unblinding  
7. Withdrawal of patient informed consent  
8. Lost to follow-up  
9. Sponsor decision (as defined in Section 5.7 Discontinuation of the Study) 
In case of temporary discontinuation of the IMP, the decision to resume the IMP should be taken 
in agreement by the Investigator, POXEL Medical Representative and Medpace Medical Monitor. 
5.6.2 Procedure for withdrawal from the study 
In the case of discontinuation of IMP for any reason listed in Section 5.6.1 Criteria for 
withdrawal from the study except SAE leading to death and lost to follow-up, patients will be 
asked to perform an Early Termination Visit within 11 days after the IMP discontinuation. 
At the Early Termination Visit, patients will be considered as withdrawn patients. This visit 
will allow the Investigator to check the medical status of the patient and the patient to return all the 
IMP blister cards (used and unused), his/her patient diary and the SMBG device for review if 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020

Page 50 / 110 
applicable. The SMBG device will be kept by the patient after the end of his/her study participation 
if applicable. Investigator will complete the eCRF (Early Termination Visit section).  
The reason and date for withdrawal from the study must be documented in source documents, in 
the eCRF and reported in the IWRS. If more than one reason of study withdrawal is given, the 
Investigator should make all efforts to establish the main reason. 
If there is any medical reason for withdrawal from the study, the patient will remain under the 
supervision of the Investigator until satisfactory health has returned. The Investigator must make 
every effort to collect the information related to the outcome of the event. This information is 
recorded in the part of eCRF dedicated to AEs. If the Investigator cannot organize a follow-up visit 
to collect this information, he/she must try to call the patient and/or his/her treating physician. If 
the IMP is discontinued as a result of a SAE, the procedure described in Section 8.3.6.4 Procedure 
for Reporting Immediately Reportable Events (IREs= SAEs and Pregnancy) is to be 
implemented. 
If patients are lost to follow-up, all reasonable means of contact must be used. In addition, a letter 
must be sent to the patient and a copy filed in the patient file (if allowed by site’s Standard 
Operating Procedures). All the attempts (at least 3 by telephone by the Investigator or Clinical 
Research Coordinator (CRC) at study site) must be recorded in the patient file and reported in the 
eCRF.  
Irrespective of the withdrawal reasons, any withdrawal is to be notified immediately to the 
Medpace Medical Monitor and Poxel Medical Representative. 
5.7 Discontinuation of the Study 
The whole study may be discontinued by POXEL in the event of any of the following: 
• New information leading to unfavorable risk-benefit ratio of IMP, e.g. due to: 
▪ Occurrence of significant previously unknown adverse reactions or unexpectedly 
high intensity or incidence of known adverse reactions, or 
▪ Other unfavorable safety findings 
• POXEL’s decision that continuation of the study is unjustifiable for medical or ethical reasons 
• Poor enrollment of patients making completion of the study within an acceptable time frame 
unlikely 
• Discontinuation of development of the POXEL’s IMP  
Competent Authorities and institutional review boards/ethics committees (IRBs/ECs) will be 
informed about the discontinuation of the study in accordance with applicable regulations.

6 Investigational Medicinal Product and Other Drugs Used in the 
Trial 
According to the Article 2(d) of Directive 2001/20/EC, the definition of  an “Investigational 
Medicinal Product (IMP)” is a pharmaceutical form of an active substance or placebo tested or 
used as a reference in a clinical trial, including products already with a marketing authorization but 
used or assembled (formulated or packaged) in a way different from the authorized form, or when 
used for an unauthorized indication, or when used to gain further information about the authorized 
form” [9]. 
In this study, the terminology IMP refers both to PXL770 or placebo. 
The IMP administered are hard gelatin capsules (Swedish orange size 00). The capsules are 
packaged in blisters.   A description of the two types of capsules, PXL770 and placebo, is given in 
the IB [10]. 
All IMPs will be produced in accordance with Good Manufacturing Practice (GMP) and Annex 13 
of GMP dedicated to IMP. 
6.1 Description of Investigational Medicinal Product 
PXL770 capsules will contain 250 mg of PXL770 plus the excipients. The active pharmaceutical 
ingredient is the monohydrate potassium salt of PXL770. Placebo capsules will contain excipients 
alone, as described in the IB [10]. Both capsules have the same shape, size and appearance 
(including the same color, smell and taste).  
6.2 Dosage and Administration 
PXL770 and/or placebo capsules will be taken BID with a glass of water. An optimal interval 
between the two IMP intakes would be 12 ± 2 hours. The interval of IMP intakes must not be less 
than 6 hours.  
To harmonize IMP intake, it is recommended to take IMP at least 15 min before a meal in the 
morning time and in the evening time.  
No IMP should be taken in the morning at home before each on-site visit. IMP will be taken at 
study site after all visit assessments are performed as specified in Table 1. 
Patients will be provided with the patient diary (paper format) as specified in Table 1. IMP intake 
(date and time) will be documented by the patients in the patient diary.  
The patient diary is to be returned at each visit together with the IMP kit(s) (used and unused).

6.2.1 Single-blind Placebo Run-in Period 
At Run-in Visit (V2), patients will start an oral dose of 2 capsules of placebo BID (4 capsules per 
day). The Single-blind placebo Run-in period will last for 4 weeks from Run-In Visit (V2) to 
Randomization Visit (V3). 
First dose intake of IMP will be taken by the patient in the evening time on the day of Run-in Visit 
(V2). Last IMP intake will be at study site on the day of Randomization Visit (V3) (morning time; 
after completion of all pre-dose assessments). 
6.2.2 Double-blind Treatment Period 
The Double-blind treatment period starts on the day of the Randomization Visit (V3) (evening 
time), following randomization to one of the 4 double-blind treatment groups in this study. On the 
day of Randomization Visit (V3), the first dose of Double-blind treatment period IMP will be taken 
by the patient in the evening. 
To ensure a double-blind design, regardless of the treatment group, all patients will take an oral 
dose of 2 capsules BID of either placebo and/or PXL770 250 mg depending on the group they have 
been allocated to: 
Table 2. Treatments to be administered in the 4 treatment groups 
Treatment Group 
Number of Capsules (Total = 4 Capsules/Day) 
PXL770 250 mg QD (250 mg/day) 
- 1 capsule of PXL770 250 mg + 1 capsule of placebo 
in the morning 
- 2 capsules of placebo in the evening 
PXL770 250 mg BID (500 mg/day) 
- 1 capsule of PXL770 250 mg + 1 capsule of placebo 
in the morning 
- 1 capsule of PXL770 250 mg + 1 capsule of placebo 
in the evening 
PXL770 500 mg QD (500 mg/day) 
- 2 capsules of PXL770 250 mg in the morning 
- 2 capsules of placebo in the evening 
Placebo 
- 2 capsules of placebo in the morning 
- 2 capsules of placebo in the evening 
The Double-blind treatment period will last for 12 weeks after Randomization Visit (V3). 
The last dose of each IMP kit should be taken by the patient at site in the morning of the visit after 
completion of all pre-dose assessments. Then, the first dose from the new IMP kits dispensed 
during the visit should be taken in the evening time on the day of the visit. 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 54 / 110 
Last IMP intake will be at study site on the day of End-of-treatment Visit (V7) (morning time; after 
completion of all pre-dose assessments). 
6.2.3 Follow-up Period 
The Follow-up period starts at the end of the 12-week Double-blind treatment period. At the End-
of-treatment Visit (V7), patients will not receive an IMP kit and consequently they will not take 
IMP during the follow-up period.  
The Follow-up period will last for 1 week. 
6.3 Treatment Assignment and Blinding 
Allocation of patients to treatment groups will proceed through the use of an IWRS and will be 
performed according to the IWRS manual. 
6.3.1 Patient Numbering 
Patients will be identified during the whole study (V1 to V8) by a patient number assigned at 
Screening Visit (V1). 
The patient number consists of a unique 5-digit number using the schema XX-YYY. The first 2 
digits (XX) indicate the pre-defined study site number. The last 3 digits (YYY) identify the patient 
within the study site. The first patient entered in a study site will be assigned the number 001, the 
second will be assigned the number 002, and so on. For example, patient 04-001 will be the first 
patient screened at study site 04. So that each patient is numbered uniquely across all clinical 
databases (IWRS, eCRF…). 
Upon ICF signature by the patient and the Investigator, the Investigator (or designee) will register 
the patient in the IWRS. The patient number will be created and allocated automatically by the 
IWRS. Once assigned, the patient number must not be reused for any other patient and the patient 
number for this patient must not be changed. 
6.3.2 Treatment Assignment or Randomization 
Single-blind placebo Run-in period 
At Run-in Visit (V2), once eligibility criteria have been checked by the Investigator, the 
Investigator (or designee) will log on to the IWRS to confirm the patient eligibility and enter the 
patient into the Single-blind placebo Run-in period for 4 weeks.  
Double-blind treatment period

Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 55 / 110 
At Randomization Visit (V3), after re-confirming the eligibility criteria, the Investigator (or 
designee) will log on to the IWRS to re-confirm the eligibility and enter the patient into the Double-
blind treatment period. Patients will be randomized in a 1:1:1:1 ratio to receive either PXL770 250 
mg QD, 250 mg BID, 500 mg QD or placebo for 12 weeks.  
Randomization will be stratified according to T2DM status (T2DM patients versus non-T2DM 
patients) at Randomization Visit (V3) and according to study sites (main study site 1 vs main study 
site 2 vs main study site 3 versus other study sites).  
Patients will be assigned a unique randomization number at the Randomization Visit (V3) by 
IWRS. This randomization number identifies which record in the randomization list and therefore 
which treatment will be allocated to the patient.  
The randomization list will be generated and kept by the Medpace statistical department by a 
statistician independent of the project team. A copy will be provided to Creapharm in charge of 
medication packaging and logistics, and to the bioanalytical laboratory in charge of the PK 
assessments on samples from patients receiving PXL770. 
During the Double-blind treatment period, at each on-site visit (except at Week 2 (V4)) after all 
visit assessments and safety evaluation are performed, the Investigator (or designee) will log on to 
the IWRS for IMP kit allocation.  
All confirmation reports generated by IWRS must be stored at least in the patient file. 
6.3.3 Treatment Blinding 
6.3.3.1 Method of Blinding 
The study will be conducted using a Double-blind design with a placebo capsule that has the same 
shape, size and appearance (including the same color, smell and taste) as the PXL770 capsules. 
Whatever the dose group they will be assigned to, patients will receive the same number of capsules 
(PXL770 and/or placebo) in order to keep the blind, both during the Single-blind placebo Run-in 
period and the Double-blind treatment period. 
PXL770 and placebo capsules will be identical in packaging, labelling, schedule of administration 
and appearance. Traceability of the IMP kit content is ensured by the IMP kit number and the 
randomization list.  
Blinded IMP will be assigned according to a computerized randomization list using the IWRS. The 
IWRS will assign IMP kits containing blinded medication for each patient at each visit requiring 
IMP kit dispensation.

Page 56 / 110 
6.3.3.2 Emergency Unblinding 
Only in case of emergency, the Investigator is authorized to access the IWRS’s randomization 
system using the randomization code break provided at the beginning of the study. 
Code-breaking can be accessed via internet. The exact description of the treatment assigned to the 
individual patient will be accessible. A code-break can thus be made for any patient without 
affecting the double-blind nature of the study. Patients IMP information may only be accessed in 
the event of an emergency and out of necessity to know the identity of the allocated IMP in order 
to institute appropriate therapeutic management. The Investigator is obliged to make every effort 
to discuss the code-break with POXEL and Medpace before code breaking. Once the code is 
broken for a patient, this patient must discontinue IMP, perform Early termination Visit and 
withdraw from the study. 
In the event that a code-break is performed, the Investigator will receive a confirmation by email 
from IWRS. The Investigator must document on the confirmation printout the reason for the code-
break, and sign the document. The document has to be kept in a safe place until the end of the 
study. Once a code has been broken, the Investigator must confirm the unblinding to the Clinical 
Research Associate (CRA), the Medpace Medical Monitor and the Poxel Medical Representative 
within 24 hours in writing. 
POXEL and / or its designee(s) will also receive an authorization to access IWRS’s randomization 
information and will be attributed a specific access code that can be used if a suspected Serious 
Adverse Reaction (SAR) occurs, to assess the expectedness of the reaction. Suspected Unexpected 
Serious Adverse Reactions (SUSARs) need to be reported according to regulatory requirements 
(see Section 8.3.6.4 Procedure for Reporting Immediately Reportable Events (IREs= SAEs and 
Pregnancy)). 
6.4  Concomitant Medications and Therapies 
The use of any systemic medication will be restricted during the study, with the exception of 
ongoing authorized medications, and/or potential medications that could be required for the 
patient’s welfare, apart from contra-indicated medications as listed in Section 6.5 Non-permitted 
Medicines.  
As far as possible, no change should be made to the dosing of these concomitant medications from 
the ICF signature to the End-of-study Visit (V8). Patients must not take any unlicensed medication, 
i.e. other investigational drugs except PXL770 or placebo, during their participation in the study.  
Medications taken within 28 days prior to ICF signature and stopped before or on ICF signature 
date will be considered as prior medication.

Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 57 / 110 
Medications that are ongoing before and continue after the ICF signature will be considered as 
concomitant medication. 
Medications that will be prescribed during the study (from the ICF signature to End-of-study Visit 
(V8)) will be considered as new medication. 
Any concomitant medication must be recorded in the corresponding section of the eCRF, its dose, 
dosage form, frequency, date of onset and stop date of the medication, indication, reason and route 
used. Patients should inform the Investigator of any change in their usual treatment and any change 
should be recorded. All patients will be questioned about concomitant medication at each study 
visit. 
6.5 Non-permitted Medicines 
Patients must not take any of the following licensed medication within the 24 weeks prior to the 
Screening Visit (V1): 
• Pioglitazone 
• Insulin 
• GLP1-RA 
• SGLT2-I 
• Anticoagulant agents 
• Amiodarone 
• Bile salt chelators 
• Methotrexate 
• Equal or more than 400 U of vitamin E per day 
• Corticosteroids with significant systemic effect (e.g. oral or intravenous administrations) 
• Any other medications known to affect liver function / steatosis at the Investigator’s 
discretion 
• Strong inhibitors of CYP2C8 (i.e. gemfibrozil and clopidogrel) and CYP2C9 (i.e. tazizulam, 
miconazole and sulfaphenazole) 
• Rifampin (moderate inducer of both CYP2C8 and CYP2C9) 
• Any herbal drug or Chinese traditional medicines 
If, during the study, the administration of a non-permitted concomitant drug occurs or becomes 
necessary, e.g. because of AE, the Investigator together with the POXEL Medical Representative 
and Medpace Medical Monitor will decide whether the patient can continue the IMP.

6.6 Packaging and Labeling 
PXL770 and placebo capsules will be packaged in appropriate blister and will be labeled in English 
with respect to the regulatory requirements in the US. 
Blister: A blister contains 32 capsules corresponding to 8 days of BID treatment. The morning and 
evening doses will be clearly identified. The patient must strictly follow these indications. 
IMP kit: An IMP kit contains 4 blisters (128 capsules – 32 days). 
• During the Single-blind placebo Run-in period, 1 IMP kit containing 4 blisters (total of 
4 blisters – 128 capsules – 32 days) will be dispensed at Run-in Visit (V2). 
• During the Double-blind treatment period, 1 IMP kit containing 4 blisters (total of 4 blisters 
– 128 capsules – 32 days) will be dispensed at each dispensing visit.  
IMP kit numbering 
The IMP kit number will identify medication packs.  
Packaging and labeling will be in accordance with applicable US regulatory requirements. 
6.7  Management of IMP 
The Investigator (or designee) will be responsible for the IMP storage, dispensing, stock inventory, 
accountability and return in the view of destruction of all IMP kits. 
6.7.1 Shipment of IMP 
The depot will store and supply IMPs to the study sites. The shipments will contain the IMP kits 
as agreed upon for the timely completion of the clinical study, once the necessary regulatory 
documents have been received. 
6.7.2 Supply and Receipt of IMP 
Upon receipt of IMP, the Investigator (or designee) will check for accurate delivery and 
acknowledge receipt via IWRS. The receipt and inventory of IMP in the study site is tracked in 
IWRS. Furthermore, IMP stock at study site must be followed and documented by the Investigator 
(or designee) on a Master Accountability log throughout the whole duration of the study. 
IMP resupply will be managed automatically through IWRS.

Page 59 / 110 
6.7.3 Storage of IMP 
The Investigator (or designee) will ensure that all IMPs are stored under recommended storage 
conditions and in accordance with applicable US regulatory requirements. IMP must be carefully 
and safely stored at the study site, and separately from other drugs, in a locked area under the 
responsibility of the Investigator (or designee). Only the Investigator (or designee) will have access 
to this room.  
The storage condition of IMP will be indicated in the pharmacy manual. 
The Investigators (or designee) are reminded to check temperature daily (e.g. manually) and before 
the first dispensation of the day, at least on every working day (i.e. manually or by using alarm 
system to alert of any excursions) and ensure that thermometers are working correctly as required 
for proper storage of IMP. Any temperature excursions should be addressed according to the 
procedures described in the pharmacy manual.  
Under no circumstances, the Investigator is allowed to use IMP in conditions other than described 
in the protocol and the pharmacy manual otherwise the insurance coverage will become null and 
void. 
It must be ensured at the study site that IMP is not dispensed to a patient with an expiry date prior 
to the date of the patient’s next on-site visit. The IMP expiry date might be extended after the drug 
stability has been re-analyzed. In such case, IMP should then be re-labeled before dispensation. 
The re-labeling of the medication will be performed by an authorized person at the US depot, 
following appropriate instructions and documented. Further details of procedures will be described 
in the pharmacy manual. 
6.7.4 Dispensing, Accountability and Compliance of IMP 
IMP dispensing 
Only the IMP kit number assigned by the IWRS will be dispensed to the patient. The dispensing 
of the IMP will be carefully recorded on the appropriate drug accountability logs provided by 
Medpace. 
IMP accountability 
The Investigator (or designee) must maintain an accurate record as follows: 
• Master Accountability log recording IMP receipt, dispensing and return by the CRA to the 
depot for destruction. The global stock at study site level must be carefully tracked and 
documented on this log. The Investigator (or designee) should ensure that this stock is 
consistent with the inventory described in IWRS.

Page 60 / 110 
• Subject Accountability log recording IMP dispensing and IMP return by patient detailed in 
terms of number of capsules.    
For both logs, dates, quantities, dose, batch numbers, expiry dates and initials of the Investigator 
(or designee) must be recorded.  
The supplies, inventory and accurate IMP documentation must be available for monitoring visit, 
audit by the designated representatives of POXEL or inspection by regulatory authorities, upon 
request.  
Any unused IMP must not be discarded or used for any other purpose than the present study. IMP 
that has been dispensed to a patient must not be re-dispensed to the patient neither to a different 
patient. 
IMP compliance 
Compliance will be calculated by the Investigator (or designee) from Run-in Visit (V2) to 
Randomization Visit (V3) for the Single-blind Run-in period and from Randomization Visit (V3) 
to End-of-treatment Visit (V7) (from Day 0 to Week 12) for the Double-blind treatment period 
based on the patient diary and IMP kits returned by the patient.  
The Investigator (or designee) must document the IMP compliance in source document and in the 
eCRF. In case of inconsistency between data in the patient diary and IMP returned, the Investigator 
(or designee) should question the patient and the reported compliance will be based on Investigator 
judgment.  
The compliance will be calculated using the following formula based on the medication returned: 
Number of capsules taken×100 
Theoretical number of capsules to be taken during the period (based on on-site visit days)*  
* In case of IMP temporary interruption requested by the Investigator (e.g. due to AE), the duration 
of the temporary interruption should be deducted from the theoretical number of capsules to be 
taken during the period. 
The acceptable compliance will be within 80% - 120% (≥80 % - ≤120%). If at any visit the 
compliance does not fall within this range, it must be reported as a protocol deviation (if it occurs 
during Double-blind treatment period) and the Investigator must remind the patient to follow the 
IMP instructions.

6.7.5 Return and Destruction of IMP 
The Investigator (or designee) will reconcile capsules returned by the patients with the Subject 
Accountability Logs. The CRA will verify and confirm this reconciliation by checking IMP 
accountability logs and all IMP returns (both unused and used kits). Thereafter, the CRA will place 
IMP kits in sealed containers to be sent to a predefined location designated by POXEL, for interim 
storage. The description of IMP kits returned will be recorded on a form completed by the CRA 
and signed by the Investigator (or designee). The allowed number of sealed container returns by 
the study site is described in the pharmacy manual.  
Upon database lock and after green light from POXEL, the company in charge of IMP destruction 
will proceed with IMP kits destruction (both unused and used). They should provide certificates of 
destruction including but not limited to destruction dates, quantities and batch numbers. 
6.8 Overdose 
The packaging has been designed to prevent any overdose with a clear indication on the blisters of 
the morning and evening dose to be taken per day. Moreover, to limit the risk of overdosing while 
still allowing some flexibility in the Double-blind treatment period duration, only 1 extra daily dose 
is available per week. In total, 4 extra daily doses are provided between 2 on-site visits (4 weeks). 
For Week 2 (V4, 2 weeks after randomization), patients will have to come at the visit with the IMP 
kit but no other kit will be provided. Patients will continue to use the IMP kit provided at 
Randomization Visit (V3) until Week 4 (V5, 4 weeks after randomization). 
6.8.1 Preclinical and Clinical Status 
Clinical data available so far with PXL770 showed a good safety and tolerability profile in healthy 
Caucasian male subjects after single administration of PXL770 up to 500 mg and multiple 
administrations (10 days) up to 500 mg QD. The dose of 500 mg QD is the maximal dose tested in 
humans. 
6.8.2 Overdose Definition 
Based on available data, an overdose is considered as any dose greater than the highest daily dose 
administered as single or repeated doses in the phase I study (i.e. 500 mg per intake and per day). 
Plasma exposures (Cmax and AUCinf) were approximately linear and dose proportional up to 375 
mg and tended to saturate between 375 mg and 500 mg. Steady-state was reached after 6 days of 
treatment. The median Tmax is 1.5-2.5 hours across all doses.  Plasma exposures increase 
approximately linearly and dose proportionally.  PXL770 Cmax and exposure decrease in presence 
of food by around 60%.

However, this study will be blinded during the Double-blind treatment period. As the daily dose 
received will be unknown up to the end of the study, an overdose can only be identified relying on 
the number of capsules administered over a defined period of time. 
Based on data obtained during the single and repeated dose administration up to 500 mg in healthy 
subjects, overdose is defined by the intake of 3 capsules or more per intake and/or more than 4 
capsules per day (if morning and evening indications are followed) and/or 3 capsules or more per 
day if at least 3 capsules come from the morning part of the blister).  
Error in dosing schedule may happen as for instance misdosing (i.e. 4 capsules QD in place of 2 
capsules BID). In such cases, dosing error will be recorded in the patient file by the Investigator 
and reported as a protocol deviation by the CRA. Patient will be retrained by the Investigator and 
it will be documented in source documents.  
In any case, these overdoses based on number of capsules will need to be confirmed at the end of 
the study, once unblinding and identification of the treatment group will allow real dose calculation. 
Only doses exceeding 500 mg per day will be considered as overdose. 
Conclusion on overdose will be included in the final study report. 
6.8.3 Reporting 
Any suspicion of overdose, when occurring in the Double-blind treatment period, whether or not 
associated with an AE (serious or non-serious) must be reported to POXEL/Medpace in an 
expedited manner. 
 
6.8.4 Treatment 
No specific antidote is currently available for PXL770 and only symptomatic therapy is possible.

8 Study Assessments 
Every effort should be made to ensure that protocol-required tests and procedures are completed 
as described.  
8.1 Blood Volume 
The total blood sampling volume for individual patients in this study will be described in the central 
laboratory manual.  
Additional blood samples may be taken for safety assessments at times specified by the Investigator 
(in case of safety issue for example) with the agreement of POXEL Medical Representative. 
8.2 Efficacy Assessment 
8.2.1 Liver fat mass assessed by MRI-PDFF – Central imaging core lab 
The primary evaluation of efficacy will be based on MRI-PDFF. This primary endpoint will be the 
relative change in the percentage of liver fat mass (assessed by MRI-PDFF) from baseline 
(Randomization Visit (V3)) to Week 12 (End-of-treatment Visit, V7).  
As key secondary efficacy endpoints, the (absolute) change in the percentage of liver fat mass 
(assessed by MRI-PDFF) from baseline (Randomization Visit (V3)) to Week 12 (V7) and the 
percentage of responders defined by the percentage of patients who achieve a clinically meaningful 
reduction of at least 5 % (≥ 5%) in absolute liver fat mass as measured by MRI-PDFF at Week 12 
(V7) will be also compared between placebo and PXL770 groups. 
Local MRI facilities in each study site will complete a qualification and quality assurance process 
prior to perform MRI acquisitions. MRI scans will be then performed on qualified and standardized 
devices at high field strength (either 3 or 1.5 Tesla) without enhanced contrast agents. MRI-PDFF 
acquisition protocols will include the acquisition guidelines for multi-echo PDFF sequence for 
most common manufacturers (GE, Siemens, Philips) and field strength (1.5T and 3.0T). All 
acquisitions images will be transferred to the Medpace Core Laboratories for central calculation 
and measurement of MRI-PDFF using a validated and established technique. The imaging 
submission manual will provide sites with information on data submission to Medpace Core 
Laboratories. Central readings will be performed by masking study sites, timepoints, clinical data 
and treatment groups information.  
Fat mass results of MRI-PDFF at Randomization Visit (V3) and Week 12 (End-of-treatment Visit, 
V7) will be blinded for Investigators and POXEL until database hard lock.

Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 72 / 110 
MRI-PDFF technique will be exclusively used for assessment of liver fat mass. The image 
acquisition technique and programmable sequences used for MRI-PDFF in the study will restrict 
the obtainable diagnostic information to liver fat quantity and will not support its use for other 
clinical purposes. 
Please refer to central imaging core lab manual for further details. 
8.2.2 Other Efficacy Parameters 
The following parameters will be also determined at various timepoints to further assess efficacy:  
• Liver enzymes: ALT and AST 
• Measured metabolic parameters: FPG, HbA1c, serum insulin, C-peptide, total cholesterol, 
HDL-c, LDL-c, triglycerides, Apo A1, Apo B, FFA, glycerol and adiponectin  
• Calculated metabolic parameters: HOMA-IR, QUICKI, HOMA-β, Adipo-IR 
The homeostasis model assessment of insulin resistance (HOMA-IR), the quantitative insulin 
sensitivity check index (QUICKI) and the homeostasis model assessment of β-cell function 
(HOMA-ß) will be calculated using the fasting insulin and FPG values at visits specified in 
Table 1. The adipo-IR will be calculated using fasting insulin and fasting FFA.  
- The HOMA-IR is calculated as [11]:  
Fasting insulin (µIU/mL) × FPG (mg/dL) / 405 
- The QUICKI is calculated as [12]:  
1 / (log (FPG (mg/dL)) ＋ log (Fasting insulin (µIU/mL))) 
- The HOMA-ß is calculated as [11]:  
(Fasting insulin (µIU/mL) × 360) / (FPG (mg/dL) – 63) 
- The Adipo-IR is calculated as [13]: 
Fasting FFA (mmol/L) x Fasting insulin (µIU/mL) 
To minimize the variability in insulin concentration, two blood samples should be collected at 
a 10-min interval at each timepoint these metabolic parameters are calculated. In the above 
formulas, the mean of the two insulin results will be used. 
• hsCRP and other biomarkers of inflammation: fibrinogen and MCP-1 
• Fibrosis biomarkers: NAFLD Fibrosis score (NFS) and Fib-4 score 
The NFS is based on a combination of clinical and laboratory measurements (i.e. age, 
glycemia, BMI, platelet, albumin and AST/ALT ratio). This score has been validated in a large 
cohort of patients with biopsy-proven NAFLD (> 700 patients) [14].  
- NFS is calculated as [14]:  
1.675 + 0.037 x age (years) + 0.094 x BMI (kg/m²) + 1.13 x Impaired Fasting Glucose or 
Diabetes (yes =1; no=0) + 0.99 x AST/ALT ratio – 0.013 x platelet (109/L) – 0.66 x 
albumin (g/dL)

Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 73 / 110 
The Fib-4 score is based on a combination of clinical and laboratory (i.e. age, platelets, AST, 
ALT). This score has been created and validated in different cohorts of patients [15, 16].  
- Fib-4 score is calculated as [15]:  
(Age (years) x AST (U/L))/ (platelet (109/L) x √(ALT (UI/L))) 
• Body weight, waist circumference and waist-to-hip ratio 
For Sub-study only: 
Fructose stimulated hepatic DNL assessment and OGTT+F will be performed at baseline 
(Randomization Visit (V3)) and at Week 12 (End-of-treatment Visit, V7). The following 
parameters will be determined: 
• Fructose stimulated hepatic DNL as assessed by deuterated water incorporation in very low-
density lipoprotein (VLDL) 
• Glucose, insulin, C-peptide, FFA, glycerol: pre-dose fasting and AUC during a 3-hour 
OGTT+F; A SMBG measurement should be performed prior to the beginning of the 
procedure in order to ensure that the glycemic status of the patient allows the procedure. 
• Insulin sensitivity index using the 3-hour OGTT+F (Matsuda index [17]) 
Patients included in the sub-study will be admitted to the site at around 5:00 pm the day prior 
to Randomization Visit (V3) and the day prior to Week 12 (End-of-treatment Visit, V7). A 
blood sample will be collected to evaluate the natural abundance of the palmitate enrichment 
and the IMP will be administered before dinner which will be served at around 5:00 pm to 
6:00 pm. Patients should drink 3 doses of deuterated water 70% at around 7:00 pm, 10:00 pm 
and 03:00 am as described in Figure 2. Deuterated water 0.5% will be provided ad libitum to 
patients. This will be the only beverage allowed during DNL and OGTT+F procedures. After 
an overnight fast and after completion of pre-dose assessments as per protocol, patients will 
take their IMP at study site: last intake of single blind placebo IMP at Randomization Visit 
(V3) and last intake of Double-blind IMP at End-of-treatment Visit (V7). 
Two (2) hours after the intake of the last single blind placebo IMP (for Randomization Visit 
(V3)) or after the last intake of Double-blind IMP (for End-of-treatment Visit (V7)), two blood 
samples will be collected at a 10-min interval for evaluation of FPG, insulin, C-peptide, FFA, 
glycerol and fructose stimulated hepatic DNL. Then, patients will drink a solution containing 
75 grams of glucose and 25 grams of fructose in 5 minutes. The beginning of the drinking will 
correspond to the time 0 for the subsequent blood collections. Blood will be drawn at regular 
time-points up to 6 hours post glucose + fructose load as detailed in Figure 2. 
8.3 Safety 
8.3.1 Physical Examination 
Physical examination must be conducted by the Investigator.

Page 74 / 110 
A complete physical examination will include head, ears, eyes, nose, mouth, skin, heart and lung 
examinations, lymph nodes, gastrointestinal, musculoskeletal, and neurological systems.  
The limited physical examination will be focused on general appearance, the cardiovascular system 
as well as towards patient reported symptoms.  
Physical examinations (complete and limited) will also include height, weight, BMI, waist and hip 
circumferences for Screening Visit (V1) and weight, BMI, waist and hip circumferences for other 
visits as planned in Table 1. 
Any new clinically significant abnormal findings or worsening of conditions previously recorded 
as medical history should be documented in the source documents and reported in the eCRF as AE. 
For weight measurement, a scale with appropriate resolution will be used and should be placed on 
a stable, flat surface. Patients should remove shoes, bulky layers of clothing, and jackets so that 
only light clothing remains.  
8.3.2 Vital Signs 
One HR measurement will be taken after the patient has been rest in supine position for at least 10 
minutes and before blood samples are taken. The HR measurement will be followed by 3 BP 
measurements, using a standardized cuff adapted to the size of the patient’s arm. BP readings will 
be taken with patients comfortably in a supine position with the arms raised to the level of the heart 
and in a supported position. All readings should be recorded as accurately as possible and the same 
BP device and the same patient’s arm (preferentially the left arm) should be used for all assessments 
for a given patient. 
All 3 readings have to be recorded in the source documents and reported in the eCRF. For analysis, 
the average of the 3 BP readings will be used.  
8.3.3 Patient Diary 
Patient diary will be dispensed according to Table 1.  
Patients will be asked to report their IMP intakes (date + dose + time) and meal taken after IMP 
intakes (date + time). Any new AE or concomitant medications should be reported by the patient 
on the diary.  
At each visit, the Investigator will review the patient diary dispensed at the previous visit and will 
report in eCRF the appropriate data. To confirm the review, the Investigator will have to sign and 
date the previous patient diary and it will be kept in the patient file.

8.3.4 Supine 12-Lead ECG 
A 12-lead ECG (I, II, III, aVR, aVL, aVF, V1-V6) will be performed at the visits shown in the 
Visit Schedule Chart in Table 1 after the patient has been lying down resting for at least 10 minutes.  
Standard 12-lead digital ECGs will be recorded as single measurement at Screening Visit (V1) and 
in triplicate, at least 1 minute apart at all other visits. The ECG printout or electronic record will be 
evaluated by the Investigator and reported as “Normal” or “Abnormal” in the source documents 
and in the eCRF. If the ECG is evaluated as “Abnormal” the Investigator should document in the 
source documents as well as in the eCRF, the specific abnormality and if this abnormality is 
“clinically significant” or “not clinically significant”.  ECG printouts or electronic record will 
include date, time, patient number, and date/signature of the Investigator who reviewed the ECG. 
The ECG printouts or electronic records will be kept in the patient file. 
Any new clinically significant findings or worsening of abnormalities previously recorded as 
Medical History on the ECG will be reported as AEs, and followed up and/or treated locally until 
the AE has resolved or the condition has stabilized.  
All 12-lead ECGs will be sent to Banook for a centralized interpretation a posteriori by 
cardiologists. 
8.3.5 Laboratory Assessments 
All laboratory measurements will be performed at central laboratory using samples collected at the 
visits shown in the Visit Schedule Chart in Table 1. However, if judged necessary for the safety of 
the patients, the Investigator or POXEL may request unscheduled central laboratory assessments.  
Blood samples will be collected, handled and stored according to the instructions described in the 
central laboratory manual. 
A list of normal reference ranges will be provided by the central laboratory to POXEL and the 
Investigators before the study start. Any change in the normal reference ranges during the study 
will be forwarded by the central laboratory to POXEL and the Investigators, who will have to keep 
it in the Trial master file (TMF) and respectively, in the Investigator site file (ISF).   
Central laboratory reports must be reviewed by the Investigator as soon as received. Each parameter 
must be assessed by the Investigator and the clinical significance of the abnormal parameters must 
be documented. To confirm the review, the Investigator will have to sign and date the report and 
keep it in the patient file. 
The following panel will be evaluated.

8.3.5.4 Serum and urine Pregnancy Test 
For female patients of child-bearing potential only, a serum or urine β-HCG test will be performed 
at the visits shown in the Visit Schedule Chart in Table 1. 
8.3.6 Adverse Events 
Comprehensive assessment of AE experienced by the patient will be performed throughout the 
course of the study, from the time of the patient’s ICF signature.  
It is of the utmost importance that all staff involved in the study is familiar with the content 
of this section. The Investigator is responsible for ensuring this. 
8.3.6.1 Adverse Event Definitions 
8.3.6.1.1 Adverse Event 
An AE is any untoward medical occurrence in a patient or clinical investigation patient 
administered a pharmaceutical product, which does not necessarily have a causal relationship with 
this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a medicinal, whether 
or not considered related to the medicinal product. 
The official definition also extends to AEs occurring under placebo or in a reference group 
receiving drug or non-drug therapy. Because of regulatory requirements, events occurring during 
drug-free and pre- and post-treatment periods should also be designated as AEs. 
Therefore, safety surveillance applies to the time when the patient is included into the study (date 
of ICF signature) until the End-of-study Visit (V8) performed one week after the End-of-treatment 
Visit (V7). 
In cases of surgical or diagnostic procedures, the condition/illness leading to such a procedure is 
considered as the AE rather than the procedure itself. 
The Investigator is required to grade the severity/intensity of each AE. 
8.3.6.1.2 Adverse Drug Reaction (ADR) 
All noxious and unintended responses to a medicinal product related to any dose should be 
considered ADR. 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 78 / 110 
The phrase “responses to a medicinal product” means that a causal relationship between a 
medicinal product and an AE is at least a reasonable possibility e.g., the relationship cannot be 
ruled out.  
8.3.6.1.3 Serious Adverse Event (SAE) 
A SAE is an AE occurring during any study phase (i.e., Screening, Run-in, Treatment, Follow-up), 
that fulfils one or more of the following criteria: 
• Results in death 
• Is immediately life-threatening 
NOTE: The term “life-threatening” in this definition refers to an event in which the patient is 
at risk of death at the time of the event; it does not refer to an event that hypothetically might 
cause death if it were more severe  
• Requires inpatient hospitalization or prolongation of existing hospitalization 
NOTE: Any hospital admission with at least one overnight stay will be considered an 
inpatient hospitalization. An emergency room visit without hospital admission will not be 
recorded as a SAE under this criterion, nor will hospitalization for a procedure scheduled or 
planned before signing of ICF. However, unexpected complications and/or prolongation of 
hospitalization that occur during elective surgery should be recorded as AE and assessed for 
seriousness. 
Admission to the hospital for social or situational reasons (e.g. no place to stay, live too far 
away to come for hospital visits) will not be considered inpatient hospitalizations.  
• Results in persistent or significant disability/incapacity 
• Is a congenital anomaly/birth defect 
• Is otherwise considered as medically important 
Important medical events that may not result in death, be life-threatening, or require hospitalization 
may be considered as SAE when, based upon appropriate medical judgment, they may jeopardize 
the patient or 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 
• angioedema not severe enough to require intubation but requiring intravenous hydrocortisone 
treatment 
• blood dyscrasias (e.g. neutropenia or anemia requiring blood transfusion, or convulsions that 
do not result in inpatient hospitalization) 
• development of drug dependency or drug abuse 
Events that do not meet the definition of an SAE 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 79 / 110 
Elective hospitalizations to simplify study treatment or study procedures are not considered as 
SAE. However, all events leading to unplanned hospitalizations or unplanned prolongation of an 
elective hospitalization (e.g. undesirable effects of any administered treatment) must be 
documented and reported as SAE. 
Events not to be considered as AE/SAE 
Medical conditions present at the informed consent visit that do not worsen in severity or frequency 
during the study are defined as baseline medical conditions and are NOT to be considered as AEs. 
Abnormal laboratory findings and other abnormal investigational findings 
Abnormal laboratory findings and other abnormal investigational findings (e.g. on an ECG tracing) 
should not be reported as AE unless they are associated with clinical signs and symptoms, lead to 
IMP discontinuation or are considered otherwise medically important by the Investigator. If an 
abnormality fulfills these criteria, the identified medical condition (e.g. anemia, pancreatitis) must 
be reported as the AE rather than the abnormal value itself.  
8.3.6.2 Methods of Recording and Assessing Adverse Events 
All AEs will be collected from the time of ICF signature to the End-of-study Visit (V8). All AEs 
will be followed until the event has resolved or the condition has stabilized or until the database 
hard lock if not resolved or stabilized before. 
Complete, accurate and consistent data on all AEs experienced for the duration of the reporting 
period (defined above) will be reported on an ongoing basis in the appropriate section of the eCRF.  
The following aspects must be recorded for each event in the source documents and in the eCRF 
for AE:  
• A description of the AE in medical terms, not as reported by patients (AE verbatim) 
• The date and time of onset (start date and time) 
• The date and time of recovery (stop date and time) 
• The grade as assessed by the Investigator according to the following definitions: 
- 
Mild (awareness of event but easily tolerated) 
- 
Moderate (discomfort enough to cause interference with usual activity) 
- 
Severe (inability to carry out usual activity) 
• Seriousness: yes or no 
• The causal relationship to IMP as assessed by the Investigator; the decisive factor in the 
documentation is the temporal relation between the AE and the IMP. The following 
judgments of the causality to IMP or study procedures are to be used:

• Action taken on IMP (no change, temporary interruption, permanent discontinuation, not 
applicable) 
• Other actions (none, corrective treatment, hospitalization or prolongation of hospitalization, 
other) 
• The outcome and date of outcome according to the following definitions: 
- 
Recovered/resolved (AE disappeared) 
- 
Recovering/resolving (patient is recovering)  
- 
Not recovered/not resolved (AE remains without signs of improvement) 
- 
Recovered/resolved with sequelae 
- 
Fatal 
- 
Unknown (only applicable if patient has been lost to follow-up) 
The following aspects must be recorded in the source documents and in the eCRF for SAE: 
• A SAE medical term 
• A description of the SAE in medical terms, not as reported by patient; only the term(s) that 
fulfills the seriousness criteria should be listed (including sequence of events, symptoms, 
diagnosis, treatment and any other relevant information) 
• The seriousness criteria, according to Section 8.3.6.1, Adverse Event Definitions 
• The date of onset 
• The outcome according to criteria already mentioned 
• Causality assessed by the Investigator according to the criteria already mentioned 
• Date and time of last IMP intake prior to SAE 
If a patient experienced several times the same AE along his/her participation in the study, then 
this AE must be documented and assessed as a new AE each time. 
Each AE will be classified using the Medical Dictionary for Regulatory Activities (MedDRA®). 
8.3.6.3 Definition of the Adverse Event Reporting Period 
The AE reporting period for safety surveillance begins when the patient is included into the study 
(date of first ICF signature) and continues through the end of the study’s post-treatment Follow-up 
period, defined as the End-of-study Visit (V8). In case any AE occurs, the Investigator will follow 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 81 / 110 
up the patient until the event has resolved or the condition has stabilized. All SAEs that the 
Investigator considers related to IMP occurring after the post-treatment Follow-up period must be 
reported to POXEL. 
AE will be recorded on an ongoing basis from date of ICF signature up to the End-of-study Visit 
(V8). 
Only events that occur after the first dose intake of IMP of the Double-blind treatment period (V3) 
or if they were present prior to the first intake of IMP of the Double-blind treatment period and 
increased in severity or relationship to IMP after the first intake of IMP of the Double-blind 
treatment period will be considered as TEAEs.  
8.3.6.4 Procedure for Reporting Immediately Reportable Events (IREs= SAEs and 
Pregnancy) 
The Investigator must report immediately (within 24 hours of the Investigator’s awareness) to 
Medpace all SAEs/Pregnancy occurring from the date of ICF signature to the End-of-study Visit 
(V8) or to the last study visit performed in case of premature discontinuation.  
An AE eCRF page must be completed with as much available information within 24 hours of 
knowledge of the SAEs. 
For pregnancy the study site will be required to complete the appropriate eCRF page within 
24 hours of knowledge of the event and also complete the Manual Exposure in Utero Form once 
received from Medpace.  
Manual Back-Up Reporting Procedures 
This study is utilizing an Electronic Data Capture (EDC) system for data entry. In the event that 
the EDC system is unavailable for electronic reporting, the manual back-up reporting procedures 
below should be followed. 
• Complete a SAE or Exposure in Utero Form 
• Email (preferred) or Fax the form to Medpace Clinical Safety 
When the EDC system becomes available, the EDC system should be updated with all previously 
reported information.

8.3.6.4.1 Safety Reporting to Regulatory Authorities, Investigators and Independent 
Ethics Committees/Institutional Review Boards 
SUSARs and other safety information requiring expedited reporting will be reported to 
Investigators, Ethics Committees and/or Competent Authorities in agreement with applicable 
guidelines and US regulations. 
In accordance with ICH GCP guidelines, POXEL will inform the Investigator of “findings that 
could adversely affect the safety of patients, impact the conduct of the study or alter the IRB/EC’s 
approval/favorable opinion to continue the study.” In particular, and in line with respective US 
regulations, POXEL will inform the Investigator of AE that are both serious and unexpected and 
are considered to be related to the administered product (“suspected unexpected serious adverse 
reactions” or SUSARs). The Investigator should place copies of these safety reports in the ISF. 
National regulations with regard to safety report notifications to Investigators will be considered. 
8.3.6.5 Monitoring of Patients with Adverse Event 
Any AE that occurs during the course of a clinical trial and is possibly related to IMP must be 
monitored and followed up until the outcome is known, unless patients are documented as “lost to 
follow-up”. Reasonable attempts to obtain this information must be made and documented. It is the 
responsibility of the Investigator to ensure that any necessary additional therapeutic measures and 
follow-up procedures are performed. 
8.3.7 Pregnancy and In Utero Drug Exposure  
All pregnancies with an estimated conception date after the date of ICF signature until the End-of-
study Visit (V8) must be reported. Upon immediate notification, the Investigator (or designee) will 
complete the Pregnancy eCRF page. Medpace Clinical Safety will send the Exposure In Utero form 
to the study site for completion within 24 hours. POXEL must be notified by Medpace Clinical 
Safety within 24 hours of being notified. 
In case of pregnancy, patients will discontinue the IMP and withdraw from the study. The 
Investigator must actively follow up, document and report on the outcome of these pregnancies. 
Any abnormal outcome: 
1. Spontaneous abortion includes abortion or missed abortion 
2. Induced abortion 
3. Stillbirth

4. Death of newborn 
5. Congenital anomaly 
6. Delivery within appropriate pregnancy terms, but congenital abnormalities in the newborn  
should be reported first to Medpace Clinical Safety with 24 hours of the Investigator’s awareness. 
The Exposure In Utero form should be used for the reporting of the outcome. 
The Medpace Clinical Safety will forward pregnancy reports to POXEL the next business day. If 
the pregnancy outcome occurs following the end of the study; the Investigator will report the 
pregnancy outcome directly to POXEL. 
Newborns should be followed up for at least 8 weeks for any potential congenital anomalies. 
Pregnancy and pregnancy outcome of female partners of male trial patients need to be reported in 
the same way. The Exposure In Utero form can be used to report the pregnancy information for the 
partner of a male patient. 
8.3.8 Special Precautions  
8.3.8.1 Hypoglycemia 
PXL770 is an insulin sensitizer and preclinical data in diabetic models, showed an improvement in 
insulin sensitivity. Based on this mechanism of action, hypoglycemia is not expected. However, as 
this study allows the inclusion of T2DM patients with mono- or bi-therapy, the improvement of 
glycemic control could lead to hypoglycemia induced by the background oral hypoglycemic 
agent(s). 
Patients with T2DM should be reminded of symptoms of hypoglycemia i.e. increased sweating, 
palpitation, trembling, shaky feeling, headaches, anxiety, poor concentration, confusion, dizziness, 
irritability, hunger or pale skin.  
Patients are requested to immediately perform a finger stick glucose measurement with the SMBG 
device provided for this study if any symptoms occur that may be related to hypoglycemia but to 
avoid any delay in treating these symptoms. After the recovery of the symptoms, patients may 
report all the symptoms, date and time, dietary intake states, time of the recovery in the patient 
diary as well as blood glucose values if available. Only symptoms and / or plasma glucose 
concentration values deemed by the Investigator to meet the definition of hypoglycemia should be 
reported in the eCRF. Hypoglycemia will be reported as recommended by the FDA guidance [19]: 
- 
Hypoglycemia evidenced only by symptoms without blood glucose measurement will be 
reported as probable symptomatic hypoglycemia.

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 84 / 110 
- 
Hypoglycemia evidenced only by plasma glucose concentration of less than 70 mg/dL 
(3.9 mmol/L) will be reported as asymptomatic hypoglycemia. In case of asymptomatic 
hypoglycemia observed on SMBG, it should be reported using the verbatim of 
asymptomatic hypoglycemia (with the glucose value) reported from SMBG. 
- 
Hypoglycemia evidenced both by typical symptoms and plasma glucose concentration of 
less than 70 mg/dL (3.9 mmol/L) will be reported as documented symptomatic 
hypoglycemia. 
- 
Hypoglycemia requiring assistance of another person to administer carbohydrate or 
glucagon or other procedure will be reported as severe hypoglycemia. 
Therefore, there might be values coming from the SMBG device under the threshold for 
hypoglycemia without any associated symptoms. In such case, it is important for the Investigator 
to judge whether this has to be reported or not as an AE of hypoglycemia, depending on the clinical 
context and the overall glycemic control. 
In case of hypoglycemia, the Investigator should query the patient to understand the clinical context 
that may have explained a low glucose value (exercise, missing meal, timing of IMP intake and 
SMBG…). 
8.3.8.2 DILI 
To detect and monitor a possible DILI, the following evaluations should be performed in the 
presence of significant elevations of liver indices.  
• For patients with normal liver transaminases and total bilirubin at baseline 
(Randomization Visit (V3)):  
If patients with normal baseline (Randomization Visit (V3)) liver indices develop new elevations 
of AST or ALT or ALP >3  ULN or TBL >2  ULN values during the study, repeat testing should 
be performed within 48 to 72 hours. Investigators should also ask the patient if he/she has 
symptoms. 
If there are persistent elevations (ALT or AST >3  ULN or TBL >2  ULN) upon repeat testing, 
then close observation (as described below) should be implemented and discontinuation of drug 
should be considered. 
Drug should be discontinued, and the patient followed until resolution of symptoms or signs in the 
following situations:  
- 
ALT or AST >8  ULN 
- 
ALT or AST >5  ULN for more than 2 weeks. 
- 
ALT or AST >3  ULN and (TBL >2  ULN or INR >1.5) 
- 
ALT or AST >3  ULN with the appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia (>5%).

CONFIDENTIAL 
Page 85 / 110 
• For patients with elevations in liver transaminases or total bilirubin at baseline 
(Randomization Visit (V3)):  
If patients with abnormal baseline liver indices develop elevations of AST or ALT >2  baseline 
or TBL >2  baseline values during the study, repeat testing should be performed within 48 to 72 
hours.  Investigators should also ask to the patient if he/she has symptoms. 
If there are persistent elevations (ALT or AST >2  baseline or TBL >2  baseline values) upon 
repeat testing, then close observation (as described below) should be implemented and 
discontinuation of drug should be considered. 
Drug should be discontinued, and the patient followed until resolution of symptoms or signs in the 
following situations:  
- 
If baseline measurements were <2  ULN, discontinue if ALT or AST increases to >5  
baseline measurements.  
- 
If baseline measurements 2  ULN (<200 IU/L as per eligibility requirements), 
discontinue if ALT or AST increases to >3  baseline measurements. 
- 
If baseline measurements 5  ULN (<200 IU/L as per eligibility requirements), 
discontinue if ALT or AST increases to >2  baseline measurements. 
- 
Discontinue if ALT or AST increase >2  baseline measurements AND the increase is 
accompanied by a concomitant increase in TBL to >2  baseline measurements or the 
INR concomitantly increases by >0.2. 
- 
For any patients who present with a constellation of syndromes indicative of liver disease 
as per the Investigator’s overall assessment (i.e. fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia [>5%]). 
• Close observation for suspected drug-induced liver injury includes the following:  
- 
Repeating liver enzyme (ALT, AST, and ALP) and TBL tests 2 or 3 times weekly. The 
frequency of repeat testing can decrease to once a week or less if abnormalities stabilize 
or the study drug has been discontinued and the patient is asymptomatic. 
- 
Obtaining a more detailed history of symptoms and prior or concurrent diseases. 
- 
Obtaining a history of concomitant drug use (including nonprescription medications and 
herbal and dietary supplement preparations), alcohol use, recreational drug use, and 
special diets. 
- 
Ruling out acute viral hepatitis types A, B, C, D, and E; autoimmune or alcoholic 
hepatitis; hypoxic/ischemic hepatopathy; and biliary tract disease. 
- 
Obtaining a history of exposure to environmental chemical agents. 
- 
Obtaining additional tests to evaluate liver function, as appropriate (e.g. INR, direct 
bilirubin, lactate, liver ultrasound). 
- 
Considering gastroenterology or hepatology consultations. 
If a DILI is confirmed or suspected by the Investigator, or in case of liver function parameters 
(ALT, AST, ALT, TBL) above the threshold defined in this section, the Investigator will complete

CONFIDENTIAL 
Page 86 / 110 
an Expedited Liver Assessment Report page (ELAR) in the eCRF within 24 hours of knowledge 
of the case. If the DILI is confirmed, it should be reported in addition as an AE (see Section 8.3.6.2 
Methods of Recording and Assessing Adverse Events). 
8.4 Pharmacokinetics 
During this study, pre-dose and post-dose plasma concentration of PXL770 will be assessed as 
indicated in Table 1. 
The assays of PXL770 will only be carried out in patients who have received the active drug. Thus, 
the laboratory responsible for PK bioanalysis will be provided with a randomization list. Under no 
circumstances will this list be brought to the attention of the Investigators, or to the project team 
members. 
Pre-dose and post-dose plasma samples for PK bioanalysis will be collected at study sites and 
forwarded to central laboratory. For the determination of PXL770, blood samples will be taken by 
an indwelling catheter or direct venipuncture, as appropriate.  
Please refer to the lab manual for further explanations. 
8.5 Biobanking Samples for Post-hoc Assessments 
Blood samples for supplementary tests will be collected at visits shown in Table 1 to enable post-
hoc testing of any additional efficacy and safety parameters or any potential biomarkers related to 
liver, cardiovascular diseases or metabolic diseases in relation with the drug target. The samples 
will be frozen and stored until further use. All the biobanking samples will be destroyed within 
2 years after the final study report is issued. 
Please refer to the lab manual for further explanations. 
8.6 Pharmacogenetics 
Blood samples for genotyping purposes will be collected at visits shown in Table 1 to enable post-
hoc genetic and pharmacogenetic research on the DNA/RNA samples from patients who sign an 
optional, additional informed consent. The samples will be frozen and stored until further use. All 
samples will be destroyed within 2 years after the final study report is issued. 
Please refer to the lab manual for further explanations. 
8.7 Acceptable deviation times

9 Statistical methods 
Statistical analysis will be performed by Medpace under the supervision of POXEL. A general 
description of the statistical methods to be used to analyze the efficacy and safety data is outlined 
below. Full details of analyses will be provided in the Statistical Analysis Plan (SAP), which will 
be finalized prior to the unblinding and locking of the database. 
9.1 General considerations 
In general, summary tabulations will be presented by treatment arm and will display the number of 
observations, mean, standard deviation, median, minimum, and maximum for continuous variables, 
and the number and percent per category for categorical data.   
Unless stated otherwise, tests will be performed at the nominal alpha two-sided level of 0.05 along 
with 95% two-sided confidence intervals.  
Given the early stage of development (i.e. a Phase II trial for internal decision), no adjustment for 
multiplicity will be considered. Hence, pairwise comparisons between PXL770 doses (250 mg QD, 
250 mg BID and 500 mg QD) vs placebo and pairwise comparisons between active doses will be 
tested at the two-sided nominal level of significance of 0.05. 
The primary endpoint will be the relative change in the percentage of liver fat mass (assessed by 
MRI-PDFF) from baseline (Randomization Visit (V3)) to Week 12 (V7). 
The primary set for efficacy analysis will be the Intention-to-treat Set. 
No interim analysis is planned for this study. 
Few missing data are expected and, unless stated otherwise, they will be not replaced. 
9.2 Sample Size Determination 
Sample size determination is based on the primary endpoint, i.e. the relative change in the 
percentage of liver fat mass (assessed by MRI-PDFF) from baseline (Randomization Visit (V3)) 
to Week 12 (V7) and the following assumptions: 
• Superiority design of PXL770 compared to placebo 
• 2-sided alpha (Type 1) error = 0.05 
• Beta (Type 2) error = 0.10 (Power = 90%) 
• Expected difference (percentage change in liver fat mass):  30% 
 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 89 / 110 
• Relative change in percentage liver fat mass: standard deviation (SD) = 30%, estimated from 
previous published data [1] 
• No adjustment for multiple comparisons between PXL770 doses and placebo 
With these assumptions, the sample size is 24 evaluable patients in each group to achieve a 90% 
power for each pairwise comparison. 
Assuming a dropout rate of approximately 20%, 30 patients are to be randomized per treatment 
group (120 patients in total). 
9.3 Randomization 
A statistician independent of POXEL will prepare the randomization list. Each patient will be 
assigned to one of four treatments in a 1:1:1:1 ratio: 
• Group 1: Placebo 
• Group 2: PLX770 250 mg QD 
• Group 3: PXL770 250 mg BID 
• Group 4: PXL770 500 mg QD  
Randomization will be stratified according to T2DM status (T2DM patients versus non-T2DM 
patients) and study site (main study site 1 vs main study site 2 vs main study site 3 vs other study 
sites).  
See Section 6.3.2 Treatment Assignment or Randomization for further details of the 
randomization procedures to be applied. 
9.4 Analysis Sets 
9.4.1 Screened Analyses Set 
The Screened Analysis Set is defined as all patients who were screened for inclusion into the study. 
9.4.2 Safety analyses and Safety Set 
The Run-in Safety Analysis Set (RISS) is defined as all patients having received at least one dose 
of the single-blind placebo run-in treatment.  The population will be used to assess exposure and 
compliance with the single-blind placebo run-in treatment only. 
The Safety Analysis Set (SS) comprises all randomized patients having received at least one dose 
of the study drug (either PXL770 or placebo) and considered as-treated. Safety and tolerability will 
be analyzed on the safety set.

Page 90 / 110 
9.4.3 Efficacy Analyses  
All primary and secondary efficacy endpoints will be analyzed using the intention-to-treat set 
(ITTS). The per protocol (PP) set will be used only for the analysis of the primary endpoint to 
assess the robustness of the primary analysis. 
9.4.3.1 Randomized Set (RS):  
All patients considered as-randomized regardless of the treatment actually received. 
9.4.3.2 Intention-to-treat Set 
The ITTS consists of all as-randomized patients having received at least one dose of the IMP (either 
PXL770 or placebo).  Patients will be assigned to the treatment group as-randomized regardless of 
the treatment actually received. The ITTS will be considered as the primary set for efficacy 
analyses. 
9.4.3.3 Per Protocol Set (PPS)  
The PPS consists of all ITTS patients without any major violations of study procedures. Major 
protocol violations will be identified prior to breaking the blind. Protocol deviations will be 
reviewed and classified as minor or major during a data review meeting that will be held before 
database lock and breaking the blind.   
9.4.4 PK Population 
The PK population corresponds to the Safety Set and includes all randomized patients who have 
been treated with PXL770 according to the protocol and have provided at least one pre-dose PK 
assessment during the study. 
9.5 Efficacy analysis 
9.5.1 Primary Endpoint: relative change in the percentage of liver fat mass 
The primary analysis of efficacy will be performed on the ITTS. 
Primary analysis: 
The primary endpoint, i.e. expressed as the relative change in the percentage of liver fat mass 
(assessed by MRI-PDFF) from baseline (Randomization Visit (V3)) to Week 12 (V7), will be 
analyzed in an analysis of covariance (ANCOVA) model adjusting for treatment (PXL770 doses 
of 250 mg QD, 250 mg BID and 500 mg QD and placebo) and for stratification factors, i.e. T2DM 

PXL770 / Study No. PXL770-004

Page 91 / 110 
status (T2DM patients versus non-T2DM patients) and study site (main site 1 vs main site 2 vs 
main site 3 vs other pooled sites) and baseline liver fat mass as a covariate.  
Least square means (LSMs) of the primary endpoint for treatment groups and pairwise differences 
in LSMs will be estimated along with their p-values and 95% confidence intervals.  
Missing MRI-PDFF at Week 12 (V7) will be estimated using a multiple imputation method (fully 
conditional specification method) assuming missing at random (MAR) mechanism which will be 
detailed in the SAP. Missing baseline MRI-PDFF will not be estimated. 
Validity of the ANCOVA model will be checked (studentized residuals will be plotted against 
predicted values, etc.).   
Sensitivity analyses: 
Pairwise Wilcoxon tests stratified according to T2DM status and Site will be performed. Hodges-
Lehmann estimates along with their 95% confidence intervals will also be provided.    
The primary and sensitivity analyses will be repeated on the PPS. 
Subgroup analyses: 
Subgroup analyses will be performed: 
• within each T2DM status (T2DM patients versus non-T2DM patients). The treatment by 
T2DM status interaction will be tested.  
• within each site (main site 1 vs main site 2 vs main site 3 vs other pooled sites). The treatment 
by site (main 1 vs main 2 vs main 3 vs others) interaction will be tested. 
9.5.2 Key Secondary Endpoints 
9.5.2.1 Absolute Change in the percentage of liver fat mass   
The (absolute) change in the percentage of liver fat mass (assessed by MRI-PDFF) from baseline 
(Randomization Visit (V3)) to Week 12 (V7) will be analyzed in an analysis of covariance 
(ANCOVA) model adjusting for treatment, T2DM status (T2DM patients versus non-T2DM 
patients), site (main 1 vs main 2 vs main 3 vs others) and baseline liver fat mass. Least square 
means of the change in the percentage of liver fat mass for treatment groups (PXL770 doses of 250 
mg QD, 250 mg BID and 500 mg QD and placebo) and pairwise differences in LSMs will be 
estimated along with their p-values and 95% confidence intervals.  
Missing MRI-PDFF at Week 12 (V7) will be estimated using a multiple imputation method (fully 
conditional specification method) assuming missing at random (MAR) mechanism which will be 
detailed in the SAP. Missing baseline MRI-PDFF will not be estimated. 
Validity of the ANCOVA model will be checked (studentized residuals will be plotted against 
predicted values, etc.).  
The same sensitivity analyses proposed for the primary endpoint will be performed.

9.5.2.2 Analysis of responders    
Four types of responders will be proposed and analyzed: 
- 
Response defined as an absolute reduction in liver fat mass (from baseline 
(Randomization Visit (V3)) to Week 12 (V7)) higher than or equal to 5% (≥ 5 %). 
- 
Response defined as a relative reduction in liver fat mass (from baseline (Randomization 
Visit (V3)) to Week 12 (V7)) higher than or equal to 30% (≥ 30 %). 
- 
Response defined as a relative reduction in liver fat mass (from baseline (Randomization 
Visit (V3)) to Week 12 (V7)) higher than or equal to 50% (≥ 50 %). 
- 
Response defined as a liver fat mass value at Week 12 (V7)) that is normalized, i.e. lower 
than or equal to 5% (≤ 5 %). 
Percentages of response will be estimated within each treatment group. 
The response will be analyzed in a logistic regression model adjusting for treatment (PXL770 doses 
of 250 mg QD, 250 mg BID and 500 mg QD and placebo), T2DM status (T2DM patients versus 
non-T2DM patients), site (main 1 vs main 2 vs main 3 vs others) and baseline liver fat mass.  
Pairwise differences in treatment groups will be estimated in this model as odds ratios along with 
their p-values and 95% confidence intervals. 
Methods handling missing MRI-PDFF at Week 12 (V7) and therefore missing responder status at 
Week 12 (V7) will be detailed in the SAP. 
9.5.3 Other Secondary Endpoints 
The analysis of these secondary endpoints will be provided and fully detailed in the SAP.   
Other efficacy secondary endpoints are as follows:  
• Liver enzymes: ALT and AST 
• Measured metabolic parameters: FPG, HbA1c, insulin, C-peptide, Total cholesterol, HDL-c, 
LDL-c, triglycerides, Apo A1, Apo B, FFA, glycerol and adiponectin  
• Calculated metabolic parameters: HOMA-IR, QUICKI, HOMA-β and Adipo-IR 
• hsCRP and other markers of inflammation: fibrinogen and MCP-1  
• Fibrosis markers: NFS and Fib-4 score 
• Body weight, waist circumference and waist-to-hip ratio 
9.5.4 Exploratory Endpoints ( Sub-study only)

• Insulin sensitivity marker using a 3-hour OGTT (Matsuda) 
The timepoints for collection of each of these are given in detail in Section 7 Study Procedures 
and in Table 1. 
9.5.5 Safety Analysis 
The analysis of safety parameters will be based on the safety analysis set. In general, missing safety 
data will not be replaced. Standard safety analysis will be performed and fully detailed in the SAP. 
Safety parameters are as follows: 
9.5.5.1 Adverse Events 
AE will be coded using MedDRA®. The frequency and incidence of TEAE will be presented by 
System Organ Class (SOC) and preferred term for PXL770 treatment groups and placebo (number 
and percentage of patients experiencing at least one AE per preferred term as well as the number 
of observed events per preferred term). Separate tables will be presented by severity and by 
relationship. All AE will be presented in a full and comprehensive listing including patient number, 
treatment, severity, seriousness, action taken, outcome, relationship to treatment, onset/stop and 
duration. Details of SAE and AE leading to permanent discontinuation of IMP or to death will be 
listed separately.  
9.5.5.2 Concomitant Medications 
Previous, concomitant and new medications will be coded using the World Health Organization 
(WHO) Dictionary.  
Previous, concomitant and new medication will be tabulated and summarized by treatment groups. 
9.5.5.3 Vital Signs, ECG, Body Weight, Waist Circumference, waist to hip ratio, BMI and 
Physical Examination 
Vital signs, ECG parameters, body weight, waist circumference, waist to hip ratio and BMI will be 
summarized descriptively by treatment and timepoint. Similarly, changes from baseline 
(Randomization Visit (V3)) will be summarized. 
Physical examination results will be listed by patients and body system. 
9.5.5.4 Clinical Laboratory Data 
Laboratory findings will be evaluated using central laboratory’s normal reference ranges. Clinically 
relevant values will be flagged (please refer to central laboratory manual). Descriptive statistics

will be derived for quantitative laboratory parameters for each treatment group and timepoint. 
Similarly, changes from the baseline will be summarized. 
Values outside the normal range (N) will be categorized as H (above the normal range) or L (below 
the normal range) based on the central laboratory’s normal reference range. Shift tables will be 
presented at each post-baseline visit showing the number of patients per treatment group with N, 
H or L. 
9.5.5.5 Withdrawals of study 
Patients who withdraw from the study will be summarized by treatment group according to their 
reason of withdrawal. 
9.5.6 Analysis of Further Endpoints 
Pharmacokinetic parameters assessment will include pre- and post-dose concentrations of PXL770 
in blood at visits and timepoints specified in Table 1. 
Pharmacokinetic data (PXL770 concentrations) will be analyzed using PopPK model. The 
evaluated PK parameters will be listed and summarized by treatment groups, by visits and by 
timepoints. 
Post-hoc testing of any additional safety parameters or any potential biomarkers related to liver, 
cardiovascular diseases or metabolic diseases in relation with the drug target evaluation will be 
assessed using the Safety Set.

10 Ethical and Regulatory Aspects 
10.1 Ethics and Good Clinical Practice 
The Investigator will ensure that this study is conducted in full compliance with the principles of 
the ‘Declaration of Helsinki’ (as amended in Tokyo, Venice, Hong Kong, Somerset West, 
Edinburgh and Seoul), and with the laws and regulations of the country in which the clinical 
research is conducted. A copy of the Declaration of Helsinki will be provided to each study site. 
All studies must follow ICH GCP Guidelines and local regulations. Investigators will strictly 
ensure adherence to the stated provisions.  
For any study site staff member responsible for performing a critical task, ICH GCP experience 
and training must be documented on the Curriculum Vitae. Any study site staff member not familiar 
with or having conducted an ICH GCP training more than 2 years prior to the study initiation or 
start of involvement in the study will have to be trained before the start of the study. 
10.2 Patient Information and Informed Consent 
It is the responsibility of the Investigator to obtain informed consent according to GCP and local 
regulations from each individual participating in this study. 
An unconditional prerequisite for patients’ participation in the study is their written informed 
consent. The patient’s written informed consent to participate in the study must be given before 
any study-related activities are carried out. 
Adequate information must therefore be given to the patient by the Investigator before informed 
consent is obtained. A patient information sheet prepared in accordance with the Note for Guidance 
on GCP (ICH E6) will be provided by Medpace and validated by POXEL for the purpose of 
obtaining informed consent. In addition to providing this written information to a potential patient, 
the Investigator (or his/her designate) will inform the patient verbally of all pertinent aspects of the 
study. The Investigator (or his/her designate) must provide adequate explanation of the methods, 
objectives and potential hazards of the study. The language used in doing so must be chosen so that 
the information can be fully and readily understood by laypersons. The Investigator (or his/her 
designate) must explain to patients that they are completely free to refuse to enter the study, or to 
withdraw from it at any time for any reason. 
The ICF must be signed and dated by the patient in person at study site and the Investigator in 
person at study site. The signed and dated declaration of informed consent will remain at the 
Investigator’s site and must be safely archived by the Investigator so that the forms can be retrieved 
at any time for monitoring, auditing and inspection purposes. A copy of the signed and dated ICF 
 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 96 / 110 
should be provided to patients prior to participation. The whole consenting process must be clearly 
documented in the patient file. 
The information Leaflet and ICF will be provided in the local language. 
Whenever important new information become available that may be relevant to the patient’s 
consent, the written patient information sheet and any other written information provided to 
patients will be revised by POXEL and be submitted again to the IRB/EC for review and favorable 
opinion. The agreed, revised information will be forwarded to each patient in the study. The 
Investigator (or his/her designate) will explain the changes to the previous version and patient will 
be asked to sign the new version. 
The patient identification log must be maintained for all patients who consented to participate in 
the study, whether or not they were randomized.  
10.3 Patient Identification and Privacy 
A unique patient number (see Section 6.3.1 Patient Numbering) will be assigned to each patient 
at Screening Visit (V1). This number will serve as the patient’s identifier in the study as well as in 
the clinical study database. 
The patient’s data collected in the study (including genetic tests) will be stored under this number. 
Only the Investigator will be able to link the patient’s study data to the patient via an identification 
list kept at the study site. The patient’s original medical data that are reviewed versus eCRF data 
(source data verification process) at the study site during routine monitoring, audits and authority 
inspections will be kept strictly confidential. 
Data protection and privacy regulations will be observed in capturing, forwarding, processing, and 
storing patient data. Patients will be informed accordingly and will be requested to give their 
consent on data handling procedures in accordance with US regulations. 
10.4 Emergency Medical Support and Patient Emergency Card 
Patients included in this study will be provided with a Patient Emergency Card at Screening Visit 
(V1). The Patient Emergency Card is based on the need to provide patients with a way of 
identifying themselves as participating in this study, and subsequently to give health care providers 
access to the information about this participation that may be needed to determine the course of the 
patient’s medical treatment. 
This card is designed to provide information to health care providers who are not part of the clinical 
study; this may include the possibility of emergency unblinding if needed, in case of blinded 
studies. The Investigators, who are already aware of the protocol and treatment, have other means 

PXL770 / Study No. PXL770-004 
Protocol Version 6.0 / 24th July 2020 
 
CONFIDENTIAL 
Page 97 / 110 
of accessing necessary medical information for the management of emergencies occurring in their 
patients. 
The first point of contact for all emergencies will be the Investigator caring for the affected patient. 
The Investigator agrees to provide his or her emergency contact information on the card for this 
purpose. If the Investigator is available when an event occurs, he/she will answer any questions. 
Any subsequent action (e.g. unblinding) will follow the standard processes established for the 
Investigators. 
10.5 Patient Insurance and Compensation to Patients 
Insurance coverage shall be provided in line with the regulations. Coverage will be provided from 
the time a patient has been screened in the study, i.e. from the time the patient has given written 
informed consent.  
In the event that a patient is injured as a direct result of study participation, POXEL will reimburse 
for treatment of such injuries, as long as those costs are not covered by the patient’s health care 
payer.  However, if the patient has not complied with the study procedures, has not followed the 
instructions of the Principal Investigator or if the injury is a result of a medical condition not related 
to the IMP, the patient’s health care payer will be responsible for the costs of diagnosing and 
treating the condition.  
10.6 Institutional Review Board/Ethics committee 
Prior to commencement of the study at a given study site, the study protocol will be submitted 
together with its associated documents (Patient Information and Consent Form, IB) and any other 
relevant information (e.g. patient diary) to the responsible IRB/EC for its favorable 
opinion/approval. The written favorable opinion/approval of the IRB/EC will be filed in the ISF, 
and a copy will be filed in the TMF at Medpace. 
The study must not start at a study site before POXEL has obtained written confirmation of 
favorable opinion/approval from the concerned IRB/EC. The IRB/EC will be asked to provide 
documentation of the date of the meeting at which the favorable opinion/approval was given, and 
of the members and voting members present at the meeting. Written evidence of favorable 
opinion/approval that clearly identifies the study, the protocol version and the Patient Information 
and Consent Form version reviewed should be provided. Where possible, copies of the meeting 
minutes should be obtained. Amendments to the protocol will also be submitted to the concerned 
IRB/EC, before implementation in case of substantial changes (see Section 11.6 Changes to the 
Protocol). Relevant safety information will be submitted to the IRB/EC during the course of the 
trial in accordance with national regulations and requirements.

11 Study Management 
11.1 Data collection and CRF management 
In this study, an eCRF will be used. CRF data will be captured via EDC using ClinTrak EDC, a 
web-based tool. An eCRF will be completed for each screened patient. 
Patient diary, specifically designed for the clinical trial by POXEL and provided to the study sites 
will be given to the patients. Data collected in this patient diary are detailed in Section 8.3.3 Patient 
Diary. 
The data in the eCRF should be consistent with the relevant source documents as verified by 
Medpace’s CRA during monitoring visits. The data will be processed, evaluated, and stored in 
pseudonymous form in accordance with the data-protection regulations. 
The Investigator must ensure that any document associated with an eCRF forwarded to POXEL 
contains no mention of any patient names. 
The eCRFs will be reviewed by the Investigator for completeness and accuracy. Each patient’s 
eCRF must be signed electronically by the Investigator to document correctness and accuracy of 
data contained. Any amendments and corrections necessary must be undertaken and countersigned 
electronically by the Investigator, stating the date of the amendment/correction. The Investigator 
must state his/her reasons for the correction of important data. Electronic errors will be captured 
by the audit trail within the collection system. Details on eCRF completion will be given in the 
eCRF completion guidelines.  
The eCRFs are regulatory documents and must be suitable for submission to authorities. 
The Investigator or designee will be responsible for entering study data in the eCRF provided by 
Medpace. It is the Investigator’s responsibility to ensure the accuracy of the data entered in the 
eCRFs. The eCRF information need to be completed as soon as possible after each patient’s visit 
(but no later than 5 business days after the patient’s visit). 
In addition to eCRF, other external data are collected:  
• MRIs performed during the study will be sent to a centralized imaging core laboratory.  
Results will be electronically transferred to the Medpace Data Management Department.  
• ECGs performed during the study will be sent to a centralized ECG core laboratory. Results 
will be electronically transferred to the Medpace Data Management Department. 
• Laboratory blood and urine samplings will be sent to Medpace centralized laboratory and 
results will be transferred electronically to Medpace Data Management Department. 
• Blood samplings for DNL assessments will be sent to the University of Florida for analysis.

• PK samplings will be sent to Charles River Saint-Nazaire for analysis and results will be 
transferred electronically to Medpace Data Management Department. 
Reconciliation of all centralized data will be done by Medpace before database lock and final data 
transfer received. 
During the study, SAE data (reported on the AE form in eCRFs) will be integrated into the Medpace 
centralized pharmacovigilance database upon receipt of these forms and after a duplicate check. 
Each case will be assigned a case identification number. Each case will be assessed by POXEL 
before being reported to the relevant authorities as necessary. 
The information from the pharmacovigilance database cases will be reconciled with that in the 
clinical database. 
All these data will be integrated into a validated database. Medpace will be responsible for data 
processing, in accordance with Medpace’s data management procedures. Database lock will occur 
once quality assurance procedures have been completed. Patient Data Reports, recorded on CD or 
DVD, will be provided to the Investigators at the completion of the study. Each patient data report 
will contain all the data for a particular patient in the same format as the eCRF pages as well as 
audit trails and indexed comments. 
11.2 Handling of Protocol Deviations 
In the event of a significant deviation from the protocol due to an emergency, accident, or mistake 
(e.g. violation of informed consent process, IMP dispensing or patient dosing error, treatment 
assignment error, patient enrolled in violation of eligibility criteria, or concomitant medication 
criteria), the Investigator (or designee) will contact POXEL (or its designee) at the earliest possible 
time by telephone or by email.  The Investigator and POXEL (or its designee) will come as quickly 
as possible to a joint decision regarding the patient’s continuation in the trial.  This decision will 
be documented by the Investigator and POXEL (or its designee) and reviewed by the CRA. 
11.3 Source Data and Patient Files 
The Investigator must keep a patient file (medical file, original medical records) on paper or 
electronically for every patient included in the study. This file will contain the available 
demographic and medical information for the patient and should be as complete as possible.  
It should be possible to verify the inclusion and exclusion criteria for the study from the available 
data in this file. 
It must be possible to identify each patient by using this patient file.

CONFIDENTIAL 
Page 101 / 110 
Printouts of electronic patient file documents as stated above must be signed and dated by the 
Investigator and kept with the Investigator’s copy of the document. 
Additionally, any other documents with source data, especially original printouts of data that were 
generated by technical equipment or printouts have to be filed in the patient files. This includes 
e.g. ECG recordings, BP monitoring, laboratory value listings, patient diary, etc. All these 
documents have to bear at least the patient number, study number, scheduled time and the printing 
date printed by the recording device to indicate to which patient and to which study procedure the 
document belongs. The medical evaluation of such records should be documented as necessary and 
signed/dated by the Investigator.  
11.4 Investigator Site File and Archiving 
The Investigator will be provided with an ISF upon initiation of the study. This file will contain all 
documents necessary for the conduct of the study and will be updated and completed throughout 
the study. It must be available for review by the CRA, must be ready for inspection by Competent 
Authorities during and after the study, and must be safely archived for at least 15 years after the 
end of the study. The documents to be thus archived include the Patient Identification List and the 
signed patient ICF. If archiving of the Investigator Site File is no longer possible at the study site, 
the Investigator must notify POXEL. 
All original patient files (medical records) must be stored at the study site (hospital, research 
institute, or practice) for the longest possible time permitted by the applicable regulations, and/or 
as per ICH GCP guidelines, whichever is longer. In any case, the Investigator should ensure that 
no destruction of medical records is performed without the written approval of POXEL. 
11.5 Monitoring, Quality Assurance and Inspection by Authorities 
This study will be monitored in accordance with the ICH Note for Guidance on GCP (ICH E6). 
The CRA will perform visits to study site at regular intervals. 
During monitoring visits, the CRAs will review: 
• the conformity of ICFs with the applicable regulation 
• the compliance of patient inclusion with protocol Inclusion/Exclusion criteria 
• that the data management is adequate: source data verification, queries resolution, SAEs/ 
AEs reporting, protocol deviations reporting 
• Investigator Site File (ISF) (e.g. Protocol & Amendments and Regulatory sections, 
delegation list and training records) 
• that IMP handling is compliant with the protocol requirements 
• the compliance of centralized procedures management (e.g. central laboratory and central 
imaging) by study site staff 
• the adequacy of facilities, equipment and material management

CONFIDENTIAL 
Page 102 / 110 
In line with ICH GCP guidelines, monitoring will include verification of data entered in the eCRF 
against original patient’s records. This verification will be performed by direct access to the original 
patient records, and POXEL guarantees that patient confidentiality will be respected at all times. 
Participation in this study will be taken as agreement to permit direct source data verification. 
Representatives of appropriate POXEL personnel or its designee(s), as well as Competent 
Regulatory Authorities, must be permitted to inspect all study-related documents and other 
materials at study site, including the ISF, the completed eCRFs, IMP and the patients’ original 
medical records/files. 
The protocol, each step of the data capture procedure, and the handling of the data, as well as the 
eventual clinical study report, will be subject to independent Clinical Quality Assurance. Audits 
may be conducted at any time during or after the study to ensure the validity and integrity of the 
study data. 
11.6 Changes to the Protocol 
Changes to the protocol will be documented in written protocol amendments. Major (substantial, 
significant) amendments will usually require submission to the competent authorities and to the 
relevant IRB/EC for approval or favorable opinion. In such cases, the amendment will be 
implemented only after approval or favorable opinion has been obtained. 
Minor (non-substantial) protocol amendments, including administrative changes, will be submitted 
to the relevant IRB/EC or to competent authorities only where requested by pertinent regulations. 
Any amendment that could have an impact on the patient’s agreement to participate in the study 
requires the patient’s informed consent prior to implementation (see Section 10.2 Patient 
Information and Informed Consent) 
11.7 Clinical Study Report and Publication Policy 
11.7.1 Clinical Study Report 
After completion of the study, a clinical study report according to ICH E3 will be written by 
Medpace under the direction of POXEL.  
11.7.2 Publication 
In accordance with standard editorial and ethical practice, the results of the study will be published. 
Results from multi-center studies must be published or presented at congress only in their entirely

The coordinating Investigator will have the opportunity to review the analysis of data and to discuss 
with POXEL the interpretation of the study prior to publication.  
Any study-related article or abstract written independently by Investigators must be submitted to 
POXEL for review at least 60 days prior to submission for publication or presentation. POXEL is 
entitled to delay publication in order to protect intellectual property rights. 
The list of authors of any formal publication or presentation of study results may include, as 
appropriate, representatives of POXEL, and will be determined by mutual agreement. 
11.7.3 Disclosure and Confidentiality 
By signing this protocol, the Investigator agrees to keep all information provided by POXEL in 
strict confidence, and to request similar confidentiality from his or her staff and the IRB/EC. Study 
documents (including IB, protocol, eCRF and other protocol-related documents) will be stored 
appropriately to ensure their confidentiality. The information provided by POXEL to the 
Investigator may not be disclosed to others without direct written authorization from POXEL, 
except to the extent necessary to obtain ICF patients who wish to participate in the study.
