SYNOPSIS  
Protocol 
Number 
CB8025-21730  
Title 
A Phase 2, Double-Blind, Randomized, Placebo-Controlled Study Followed by 
Open-Label Extension and Safety Follow-Up Phases to Evaluate the Activity of 
Seladelpar in Subjects with Nonalcoholic Steatohepatitis (NASH) 
Study Phase 
Phase 2 
Study Design 
This is a 52-week double-blind (DB), randomized, placebo-controlled, dose-ranging 
study followed by a 52-week open-label extension (OLE). An additional Safety 
Follow-Up (SFU) phase will continue for up to 1 year after the Week 52/Early 
Termination (ET) liver biopsy in subjects with significant histologic findings. 
Number of 
Investigational 
Sites 
Up to 15 sites in the U.S.A. 
Objectives 
Primary Objectives  
1. To evaluate the effect of seladelpar on hepatic fat fraction, as assessed by 
magnetic resonance imaging-proton density fat fraction (MRI-PDFF) at Week 12 
in the DB phase 
2. To evaluate the safety and tolerability of seladelpar in the DB, OLE and SFU 
phases 
Secondary Objectives 
1. To evaluate the effect of seladelpar on MRI-PDFF at Week 26 and Week 52 in 
the DB phase 
2. To evaluate the effect of seladelpar on histological improvement of nonalcoholic 
fatty liver disease activity score (NAS) at Week 52 in the DB phase 
3. To evaluate the effect of seladelpar on histological improvement of fibrosis at 
Week 52 in the DB phase   
4. To evaluate the effect of seladelpar on metabolic biochemical markers and 
biochemical markers of inflammation in the DB and OLE phases 
Exploratory Objectives  
1. To evaluate the effect of seladelpar on biochemical markers of fibrosis in the DB 
and OLE phases  
2. To evaluate the effect of seladelpar on fibrosis and inflammation as assessed by 
magnetic resonance elastography (MRE) and LiverMultiScan (LMS) in the DB 
phase 
3. To evaluate AST/platelet ratio index (APRI) and fibrosis-4 (FIB-4) in the DB 
and OLE phases  
4. To assess markers of target engagement including 7-alpha-hydroxy-4-cholesten-
3-one (C4), serum bile acids and fatty acid oxidation (FAO) tests in the DB and 
OLE phases

5. To evaluate histology, biochemical markers and FibroScan® during the SFU 
phase in subjects with significant histologic findings on the Week 52/ET liver 
biopsy 
Study Outcome 
Measures 
Primary Outcome Measures 
1. Relative change in MRI-PDFF at Week 12 in the DB phase 
Adverse events (AEs) and/or treatment emergent adverse events (TEAEs), physical 
exams, vital signs, electrocardiograms (ECGs), biochemistry, hematology, and 
urinalysis as determined by investigator assessment for causality and grading by 
National Cancer Institute Common Terminology Criteria for Adverse Events 
(NCI CTCAE), Version 4.0 in the DB, OLE and SFU phases 
Secondary Outcome Measures 
1. Absolute change in MRI-PDFF at Week 12, 26, and 52 in the DB phase 
2. Relative change in MRI-PDFF at Week 26 and 52 in the DB phase 
3. Proportion of subjects with a relative decrease in MRI-PDFF ≥ 30% at Week 12, 
26, and 52 in the DB phase 
4. Proportion of subjects with normalization of MRI-PDFF (defined as a fat fraction 
of < 5%) at Week 12, 26, and 52 in the DB phase 
5. Proportion of subjects with an absolute MRI-PDFF change > 5% at Weeks 12, 
26, and 52 in the DB phase 
6. Proportion of subjects with reversal of nonalcoholic steatohepatitis (NASH) and 
no worsening of hepatic fibrosis (centrally scored histology at Week 52) in the 
DB phase. The reversal of NASH is defined as the absence of hepatocellular 
ballooning (score of 0) and no or minimal inflammation (score of 0 or 1)

performed to collect safety and eligibility labs. 
 
SFU Phase Enrollment Criteria 
 
Subjects entering the SFU phase of the study must fulfill the following criteria: 
 
1. Presence of significant histologic findings other than NASH on the Week 52 
or Early Termination liver biopsy 
2. Received seladelpar during the DB phase for at least 6 months.  
Study Design 
and Procedures 
DB Phase 
This phase of the study is designed as a dosing ranging proof-of-concept study to 
evaluate the safety and potential efficacy effects of seladelpar on hepatic fat fraction 
(MRI-PDFF). The study includes liver biopsies to confirm that subjects have 
histological evidence of NASH at screening and to evaluate histological 
improvement in NASH and fibrosis after 52 weeks of treatment.  
Approximately 175 subjects will be randomly assigned to receive placebo, seladelpar 
10 mg/day, seladelpar 20 mg/day or seladelpar 50 mg/day at a 1:2:2:2 ratio. Subjects 
will be stratified by diabetic status (yes/no) and fibrosis stage (F1 versus F2-3). Study 
drug (placebo or seladelpar) will be taken in a blinded manner orally once a day for 
a period of 52 weeks.  
The screening period will be up to 10 weeks, the blinded treatment period will be up 
to 52 weeks, and a follow-up period of 4 weeks after the last dose of study drug. 
During the treatment period, the first on-treatment visit will occur 4 weeks after 
initiation of the study drug. Subjects will then be evaluated in clinic every 4 weeks 
until Week 12. After Week 12, visits will be 6-7 weeks apart.  Subjects will also be 
contacted by phone or email at Weeks 19, 32 and 45. The amount of fat in the liver 
will be evaluated by MRI-PDFF at baseline, Weeks 12, 26, and 52. A liver biopsy 
will be performed twice during the study: at baseline and at Week 52.  
The primary efficacy analysis will be the change from baseline to Week 12 in 
MRI-PDFF. The study will continue in a blinded fashion until the Week 52 biopsy is 
collected.

OLE Phase 
All subjects who participate in the DB phase, complete the 52-week biopsy and the 
56-week follow-up labs, and meet the specified enrollment criteria will be offered 
participation in the OLE phase of the study. Subjects will not be required to have any 
additional liver histology, imaging or elastography assessments for enrollment or on-
treatment assessments of treatment effect. The OLE Day 1 visit may be combined 
with the Week 56 visit in the DB phase. Informed Consent may occur at Week 52 or 
Week 56 in the DB phase for subjects still active in the DB phase or any time prior 
to any OLE procedures in patients who have completed the DB phase. Eligibility 
assessment may occur on or after the Week 56 in the DB phase. Laboratory 
assessments from the DB phase Week 52 visit should be used to determine OLE 
eligibility if the DB phase Week 56 visit and OLE phase Day 1 visit are planned to 
be completed on the same day. Lab assessments from the DB Week 56 visit may be 
used for OLE eligibility assessment if less than 45 days from that visit. If greater than 
45 days have elapsed from DB phase Week 56 visit, subjects should complete an 
unscheduled visit where all lab assessments required for DB phase Week 56 are 
retested. The results from the re-test must be available and assessed for eligibility 
prior to the Day 1 visit. Subjects must also be clinically stable based on the 
investigator’s medical judgement and key enrollment criteria to enter the OLE. Clinic 
visits during the 52-week OLE phase will occur at Day 1 and Weeks 2, 13, 26, 39 
and 52 with a final end of study (EOS) visit approximately at Week 56. The primary 
objective of the OLE phase is to assess long-term safety and treatment effect as 
measured by biochemical tests after an additional 52 weeks of treatment. 
 
SFU Phase 
All subjects who participated in the DB phase that have significant histologic findings 
other than NASH on the Week 52 or ET liver biopsy and received active seladelpar 
for at least 6 months will be asked to enroll in the SFU phase. Subjects in the placebo 
dosing group will not be enrolled into the SFU phase. After informed consent is 
obtained, an SFU visit will be performed at 6 months ± 4 weeks, after the Week 52 
or ET liver biopsy. A liver biopsy will be obtained to reassess the status of the original 
significant histologic findings. Other study procedures performed during the visit 
include a physical exam, vital signs, safety laboratory assessments, exploratory liver 
injury biomarker assessments, and FibroScan®. Subjects with resolution or 
stabilization of the observed histologic findings will have completed the SFU phase, 
and no further visits or assessments will be required. Subjects with worsening of the 
observed histologic findings will be followed up by phone at 3-month intervals and 
may be requested to have additional SFU visits with a repeat of some or all of the 
above procedures.

Statistics 
Populations for Analysis: 
Safety: Any subject who receives at least one dose of study drug.  
Intent-to-Treat (ITT): Any subject who is randomized and receives at least one 
dose of study drug. 
Modified Intent-to-Treat (mITT): Any subject who is randomized, receives at 
least one dose of study drug, and has Baseline and Week 12 MRI-PDFF.  
Modified Intent-to-Treat with Biopsy (mITTb): Any subject who is randomized, 
receives at least one dose of study drug and has Baseline and Week 52/early 
termination (ET) liver biopsies.  
Per-Protocol (PP): Any subject who is randomized and receives at least one dose of 
study drug, has Baseline and Week 52/ET liver biopsies and does not have a protocol 
violation that is deemed to impact the efficacy analysis.  
Population Analyses: 
The safety analysis will be conducted on the Safety population. Efficacy analyses 
will be conducted on the ITT, mITT, mITTb, and the PP populations. The mITT 
population will be used for the primary efficacy analysis. 
Statistical Methods: 
All statistical comparisons will be made at a two-sided alpha of 0.05. Treatment 
comparisons of the primary efficacy endpoint will be tested using a hierarchical 
“fixed-sequence” approach to assess clinical benefit of each of the seladelpar dose 
levels versus placebo, starting first with the 50 mg dose at a 5% alpha level. If 
positive, the seladelpar 20 mg dose will be compared to placebo at a 5% alpha level. 
If both seladelpar 20 mg and 50 mg doses are statistically superior to placebo then 
the testing will continue to the 10 mg dose vs placebo.  
Additional consideration for the testing procedures for alpha control will be discussed 
in the statistical analysis plan (SAP). 
Sample Size: 
A sample size of 175 subjects (50 subjects per each dose of seladelpar and 25 subjects 
for placebo) provides at least 80% power to detect a pairwise treatment difference of 
at least 20% between the active and placebo groups with respect to a relative change 
from baseline in hepatic fat fraction, as assessed by MRI-PDFF at Week 12. Power 
calculations were performed using a standard t-test, allowed for a 12% dropout rate 
(6 subjects per seladelpar arm, 3 subjects for the placebo arm), and a pooled standard 
deviation of 26 for the relative change endpoint.  
Primary Efficacy Analysis: 
Pairwise comparisons between each dose of seladelpar versus placebo with respect 
to the relative change in hepatic fat fraction as assessed by MRI-PDFF at Week 12 
will be conducted using analysis of covariance (ANCOVA). The LS means, 
standard errors, 95% confidence intervals (CIs), and p-values will be provided from 
an ANCOVA model with percent change from baseline in MRI-PDFF as the

dependent variable, treatment group, diabetic status, and fibrosis stage as factors 
and baseline MRI-PDFF as a covariate. 
Relative change will be calculated as:  
[MRI-PDFFWEEK12 – MRI-PDFFBASELINE] ×100 / MRI-PDFFBASELINE. 
Top-Line Results 
The 12-week Primary Analysis, including top-line results for efficacy and safety, will 
be provided and communicated when it becomes available and before study 
completion. These results will be provided by treatment group, but individual patient 
data will remain blinded and the study will continue as a double-blind study until its 
completion. Details of the conduct of the Primary Analysis will be provided in the 
SAP. 
Secondary Efficacy Analyses: 
Comparisons between each seladelpar dose versus placebo with respect to the 
absolute change in hepatic fat fraction as assessed by MRI-PDFF at Week 12, 26 and 
52 will be conducted using mixed model repeated measures analyses, with factors for 
scheduled time point, treatment, time point by treatment interaction, baseline diabetic 
status, and fibrosis stage, with the baseline hepatic fat fraction as a covariate. 
Supportive analyses will be conducted using Wilcoxon rank-sum tests, stratified by 
diabetic status and fibrosis stage.  
Comparisons between each seladelpar dose versus placebo with respect to the relative 
change in hepatic fat fraction as assessed by MRI-PDFF at Week 26 and 52 will be 
conducted using mixed model repeated measures analyses with factors for scheduled 
time point, treatment, time point by treatment interaction, baseline diabetic status, 
and fibrosis stage, with the baseline hepatic fat fraction as a covariate. Supportive 
analyses will be conducted using Wilcoxon rank-sum tests, stratified by diabetic 
status and fibrosis stage. 
Each seladelpar dose will be compared versus placebo for the number and percent of 
subjects with normalization of hepatic fat content (<5%) at Week 12, 26, and 52 using 
Cochran-Mantel-Haenszel tests, stratified by diabetic status and fibrosis stage. 
Similar analyses will be performed for:  
• 
number and percent of subjects with an absolute change > 5% on MRI-PDFF 
at Week 12, 26, and 52 
• 
number and percent of subjects with a relative decrease in hepatic steatosis 
of > 30% on MRI-PDFF at Week 12, 26, and 52 
• 
number and percent of subjects with reversal of NASH with no worsening of 
fibrosis as defined by centrally scored histology assessment at 52 weeks of 
treatment 
• 
number and percent of subjects with improvement by at least one stage in 
fibrosis (NASH Clinical Research Network Classification) without 
worsening of NASH 
• 
number and percent of subjects with a 2-point decrease in NAS 
Efficacy-related laboratory data will be summarized by laboratory parameter, 
treatment group and study visit for the DB and OLE phases.

INTRODUCTION  
1.1 
NASH  
Nonalcoholic steatohepatitis (NASH) defines a subgroup of nonalcoholic fatty liver disease where 
steatosis coexists with hepatic cell injury (apoptosis and hepatocyte ballooning), and inflammation 
(Chalasani et al., 2012). NASH is closely associated with overweight/obesity, type 2 diabetes 
mellitus, and cardiometabolic conditions that define the metabolic syndrome (Ratziu et al., 2010). 
Because of the prevalence of these comorbidities, NASH is emerging as the most common chronic 
liver disease. 
NASH promotes liver fibrosis and some patients progress to cirrhosis, liver failure, hepatocellular 
carcinoma, or require liver transplantation (Vernon et al., 2011). Compared with the general 
population, liver-related mortality is increased 10-fold in NASH patients (Ekstedt et al., 2006). 
NASH is also a multisystem disease that could worsen insulin resistance, the metabolic syndrome, 
and systemic inflammation (Yki-Jarvinen et al., 2014). Consequently, NASH patients also have an 
increased rate of cardiovascular events. and the leading cause of death is cardiovascular events 
(Vernon et al., 2011). 
There are currently no approved therapies for NASH. 
1.2 
Seladelpar 
1.2.1 Overview 
Seladelpar is a potent and selective PPAR- agonist. Seladelpar is being developed for the 
treatment of primary biliary cholangitis (PBC) in subjects with inadequate response to 
ursodeoxycholic acid (UDCA) or who are intolerant to UDCA, for the treatment of homozygous 
familial hypercholesterolemia (HoFH), and NASH. Seladelpar could also be developed for other 
disorders of lipid metabolism or disorders characterized by chronic intra-hepatic cholestasis. 
1.2.2 Mechanism of Action 
Seladelpar is a potent and selective peroxisome proliferator receptor delta (PPAR-) agonist, and 
is a key regulator of lipid metabolism, cholesterol transport, bile acid synthesis, and 
inflammation/fibrosis. Ligand binding to PPAR- results in activation and repression of its target 
genes by which it regulates the above processes. In the liver, PPAR- is expressed in hepatocytes, 
cholangiocytes, Kupffer and stellate cells (Iwaisako et al., 2012; Xia et al., 2012).  
The activity of seladelpar in NASH was studied in a diabetic, dyslipidemic obese mouse model 
(the foz/foz mouse model; Haczeyni et al., 2017). Seladelpar reversed NASH pathology and 
reduced fibrosis while improving insulin sensitivity and decreasing inflammation. These effects 
appear to be a consequence of its effects on lipid metabolism including reduction of lipotoxic 
species, which are key pathological drivers of NASH and fibrosis. 
For more detailed information, see the Seladelpar Investigator’s Brochure. 
1.2.3 Seladelpar in NASH 
In a preclinical diabetic obese mouse model of nonalcoholic steatohepatitis (NASH), the foz/foz 
mouse model (Haczeyni et al., 2017), seladelpar reversed NASH in all treated mice, and completely

eliminated ballooning while reducing inflammation and steatosis. The activities observed with 
seladelpar treatment in mice included reduction in hepatic fat (including lipotoxic lipids, free and 
total cholesterol), reduction in staining for Kupffer cell and macrophage infiltrates, decreased 
collagen deposition, decreased serum levels of alanine aminotransferase (ALT), and reversal of 
hyperglycemia, hyperinsulinemia, and insulin resistance.   
In a phase 2 study of seladelpar in obese patients with mixed dyslipidemia, a population that is 
presumed to include patients with fatty liver disease, seladelpar treatment for 8 weeks decreased 
TG and LDL-C levels. Additionally, seladelpar decreased small dense pro-atherogenic LDL 
lipoproteins, increased HDL-C concentrations, and HOMA-IR, hs-CRP, ALP, and GGT 
(Bays et al., 2011; Choi et al., 2012). Thus, the cardiovascular, metabolic and anti-inflammatory 
activities observed in patients further justify the evaluation of seladelpar as a candidate for the 
treatment of NASH. 
The interim analysis of the 12-week primary endpoint for the DB phase of this ongoing study 
provided initial clinical experience with seladelpar in NASH patients. A total of 181 subjects, with 
biopsy-confirmed NASH and a liver fat content (LFC) greater than 10%, were randomized into the 
trial to receive either placebo or seladelpar 10 mg, 20 mg, or 50 mg once-daily. The enrolled 
subjects had established NASH with a mean NAFLD Activity Score (NAS) of 5.2 at baseline, with 
83% of subjects having stage 2 or stage 3 fibrosis and mean LFC by magnetic resonance 
imaging-proton density fat fraction (MRI-PDFF) of 21%. The primary endpoint was the relative 
change in LFC from baseline to 12 weeks. The study remains blinded and will continue to 52 weeks 
with assessments including a liver biopsy, non-invasive imaging evaluations, and biomarker 
assessments of inflammation and fibrosis. Changes in LFC as measured by MRI-PDFF at week 12 
demonstrated minimal reductions in liver fat that were not significant when compared to placebo. 
However, treatment with seladelpar resulted in robust and clinically meaningful reductions in 
markers associated with liver injury, including ALT, ALP and GGT, in a dose-dependent manner. 
Treatment with seladelpar also resulted in reductions in LDL-C and TG. There were no significant 
changes in high-density lipoprotein cholesterol. The most common (>5%) treatment emergent 
adverse events included nausea, constipation, dizziness, headache, gastroesophageal reflux disease 
and upper abdominal pain. The majority of treatment emergent adverse events (TEAE) were mild 
to moderate in severity and deemed unrelated to study drug. There were two serious adverse events 
that occurred after randomization through week 12, neither of which were deemed to be related to 
study drug. 
Based on the identified pharmacologic activities in vitro, in animals and in humans as well as the 
treatment effect and safety/tolerability profile to date, seladelpar represents a potentially important 
therapeutic option for the treatment of NASH.

1.5 
Rationale for Dose Selection in the DB Phase 
The proposed dosing for the DB phase of the study is 10, 20, and 50 mg administered once daily 
for up to 52 weeks.  
The clinical experience thus far with seladelpar at daily doses of 50 mg and 100 mg for 8 weeks in 
obese males and females with mixed dyslipidemia (Bays et al., 2011), and at a daily dose of up to 
200 mg for 3 weeks in healthy volunteers, indicates that seladelpar was well tolerated and appeared 
generally safe.  
The beneficial treatment effects in the dyslipidemia study (lowering of TG, LDL-C, free fatty acids, 
and hs-CRP) do not appear to be meaningfully better at 100 mg/day than at 50 mg/day. Because 
the baseline characteristics of the study population enrolled in the Phase 2 mixed dyslipidemia 
study (obese, hyperlipidemic, insulin resistant, hypertension) overlaps with the NASH population, 
it is anticipated that the beneficial metabolic effect of seladelpar at doses of 50 mg/day will be 
translated to the NASH population. Thus, this dose has been selected as the maximum dose to be 
studied in the proposed NASH study. 
In PBC, studies have indicated that seladelpar at dose of 2, 5, and 10 mg, retains a relevant clinical 
activity to improve markers of cholestasis, markers of inflammation, and improve metabolic 
markers. There was a dose ranging activity from 2 to 10 mg/day with 10 mg/day demonstrating the 
best risk/benefit profile. For these reasons, a seladelpar a dose of 10 mg/day has been selected for 
the proposed NASH study as the dose with a potentially minimal level of activity. 
The dose of 20 mg/day has been selected to complete the approximate 2-log dose range evaluation 
in the study. Given there are no approved treatments for NASH, the risks versus benefit of 
seladelpar in NASH patients at doses of 10, 20, and 50 mg/day is acceptable. 
1.6 
Rationale for Dose Selection in the OLE Phase 
The proposed seladelpar daily doses to be studied in the OLE phase of the study is 50 mg dosed 
daily for an additional 52 weeks. This dose and duration of exposure are supported by the estimated 
safety exposure margins from the repeat dose toxicity studies of 26 weeks in Sprague-Dawley rats 
and 52 weeks in cynomolgus monkeys (Table 4).

The dose selection is further supported by the treatment effect and safety/tolerability at the 12-week 
primary endpoint interim analysis from the ongoing DB phase of this study. Although there was 
no significant reduction in liver fat content, seladelpar significantly decreased key markers of 
hepatic injury (ALT, ALP, GGT) in a dose dependent manner was the greatest magnitude of effect 
observed with the 50 mg dose (Table 5). ALT declined up to 37.5% or 32 U/L in 12 weeks. These

reductions in ALT are significantly greater than the 17 U/L threshold that has been correlated with 
histologic improvement in NASH. GGT also decreased significantly, suggesting a reduction in 
hepatocellular oxidative stress. Significant reductions in ALP at 12 weeks were observed, 
supportive of a decrease in hepatocellular bile acids. The marked changes in these liver enzymes 
collectively suggest the potential to impact ballooning and lobular inflammation, the two key 
components of NASH resolution.

Seladelpar demonstrated a favorable safety and tolerability profile at all doses evaluated in this 
study. The most common (>5%) TEAEs in the overall total population are listed in Table 6. The 
majority of TEAEs were mild in severity and deemed unrelated to study drug. Lipid and metabolic 
parameters remained stable or improved, supportive of a favorable cardiovascular risk profile. In 
general, the TEAEs were comparable across the dosing groups, with no overt safety signals to 
suggest the 50 mg dose is more poorly tolerated than the overall study population.

tolerability at the dose with greatest magnitude of effect on relevant biomarkers. 
1.7 
Rationale for SFU Phase 
A key secondary endpoint of the current study is change from Baseline in fibrosis and NASH 
histology at Week 52/End of Treatment. As part of the assessment plan for the histologic 
endpoint, an initial batch 52-week biopsies (n=112) were grouped for pathology review. Two 
highly experienced NASH pathologists, blinded to study treatment, convened on 20 November 
2019 to initiate the reading of the initial Week 52/End of Treatment biopsy slides. The 
NASH-CRN scoring system for NASH and fibrosis was used as well as the identification of any 
portal inflammation or other significant non-NASH incidental findings. Upon reading the initial 
set of slides, the pathologists identified significant non-NASH histologic findings in 31 subjects. 
These findings included histopathology consistent with interface hepatitis, bile duct injury and/or 
porto-sinusoidal vascular disease (PSVD) and were described as concerning and atypical in 
NASH.  
In contrast to the histological findings, there were no biochemical signals of drug-induced liver 
disease or injury during the study period. A review of TEAEs in subjects with histological 
findings did not reveal any outlier events and were consistent with the full population. In 


CymaBay Therapeutics, Inc

Page 31 of 77 
addition, no significant liver-related adverse effects or clinical evidence of hepatic 
decompensation have been observed in the full population dosed to date, nor in the 31 subjects 
with histological findings.  
These findings were reported to the FDA, and upon review a decision was made to terminate and 
unblind the Phase 2 studies in NASH (CB8025-21730). Follow-up correspondence from the FDA 
has requested CymaBay to obtain additional histologic, laboratory and imaging assessments in 
order to assess the resolution or persistence of the histologic findings as well potentially identify 
any predictive markers for these unexpected events. Information collected during the SFU phase 
will be used to assess on-going subject safety.

STUDY DESIGN 
DB Phase 
This phase of the study is designed as a dosing ranging proof-of-concept study to evaluate the 
safety and potential efficacy effects of seladelpar on MRI-PDFF. The study includes liver biopsies 
to confirm that subjects have histological evidence of NASH at screening and to evaluate 
histological improvement in NASH and fibrosis after 52 weeks of treatment.  
Approximately 175 subjects will be randomly assigned to receive placebo, seladelpar 10 mg/day, 
seladelpar 20 mg/day or seladelpar 50 mg/day (1:2:2:2 ratio). Subjects will be stratified by diabetic 
status (yes/no) and fibrosis stage (F1 versus F2-3). Study drug (placebo or seladelpar) will be taken 
in a blinded manner orally once a day for a period of 52 weeks.  
The screening period will be up to 10 weeks, the blinded treatment period will be up to 52 weeks, 
and a follow-up period of 4 weeks after the last dose of study drug. During the treatment period, 
the first on-treatment visit will occur 4 weeks after initiation of the study drug. Subjects will then 
be evaluated in clinic every 4 weeks until Week 12. After Week 12, visits will be 6-7 weeks apart.  
Subjects will also be contacted by phone or email at Weeks 19, 32 and 45. The amount of fat in the 
liver will be evaluated by MRI-PDFF at baseline, Weeks 12, 26, and 52. A liver biopsy will be 
performed twice during the study: at baseline and at Week 52.  
The primary efficacy analysis will be the change from baseline to Week 12 in MRI-PDFF. The 
study will continue in a blinded fashion until the Week 52 biopsy is collected.  
OLE Phase 
All subjects who participate in the DB phase, complete the 52-week biopsy and the 56-week 
follow-up labs, and meet the specified enrollment criteria will be offered participation in the OLE 
phase of the study. Subjects will not be required to have any additional liver histology, imaging or 
elastography assessments for enrollment or on-treatment assessments of treatment effect. The OLE 
Day 1 visit may be combined with the Week 56 visit in the DB phase. Informed Consent may occur 
at Week 52 or Week 56 in the DB phase for subjects still active in the DB phase or any time prior 
to any OLE procedures in patients who have completed the DB phase. Eligibility assessment may 
occur on or after the Week 56 in the DB phase. Laboratory assessment for OLE suitability may be 
required if more than 45 days have elapsed since last lab collection to anticipated first OLE dosing. 
If greater than 45 days have elapsed since the last lab collection, subjects must complete an 
unscheduled visit where all labs collected at Week 56 will be retested, with the results available 
and assessed prior to the Day 1 visit. Subjects must also be clinically stable based on the 
investigator’s medical judgement and key enrollment criteria to enter the OLE. Clinic visits during 
the 52-week OLE phase will occur at Day 1 and Weeks 2, 13, 26, 39 and 52 with a final EOS visit 
at approximately Week 56 visit. The primary objective of the OLE phase is to assess long-term 
safety and treatment effect as measured by biochemical tests after an additional 52 weeks of 
treatment.

SFU Phase 
All subjects who participated in the DB phase that have significant histologic findings other than 
NASH on the Week 52 or ET liver biopsy and received active seladelpar for at least 6 months 
will be asked to enroll in the SFU phase. Subjects in the placebo dosing group will not be 
enrolled into the SFU phase. After informed consent is obtained, an SFU visit will be performed 
at a minimum of 6 months after the Week 52 or ET liver biopsy. A repeat liver biopsy will be 
obtained to reassess the status of the original significant histologic findings. Other study 
procedures performed during the visit include a physical exam, vital signs, safety laboratory 
assessments, exploratory liver injury biomarker assessments, and FibroScan®. Subjects with 
resolution or stabilization of the observed histologic findings will have completed the SFU phase, 
and no further visits or assessments will be required. Subjects worsening of the observed 
histologic findings will be followed up by phone at 3-month intervals and may be requested to 
have additional SFU visits with a repeat of some or all of the above procedures.

STUDY MEDICATIONS  
6.1 
Clinical Supplies 
6.1.1 Investigational Product, Dosage, and Mode of Administration 
In the DB phase, seladelpar will be supplied in a blinded fashion in 5 mg, 10 mg, and 25 mg 
capsules. Matching placebo capsules will also be provided.  
The study drug (seladelpar or placebo) will be administered orally, once daily. The subject will 
take 2 capsules daily, approximately at the same time each day. If dose adjustment occurs, the study 
drug might be administered at doses of 5 mg, 10 mg, and 25 mg. In case of dose adjustment, the 
subject will take 1 capsule daily. 
In the OLE phase, Seladelpar will be supplied only as 25 mg capsules. No placebo capsules will 
be provided. 
6.1.2 Packaging, Labeling and Shipping 
The Sponsor will provide the Investigator with packaged study drug labeled in accordance with 
specific country regulatory requirements. For the subjects who meet the criteria for dose adjustment 
(per Section 7.4), the subject will be instructed to use the same study drug kit but take 1 capsule 
per day instead of 2 capsules per day. 
6.1.3 Accountability of Clinical Supplies  
The Investigator or a designee will keep a record of the dates and amounts of study medication 
received, the amount dispensed to study subjects, and the amount unused. 
6.1.4 Stability of Study Medication 
All supplies of medication must be stored as defined on the primary packaging to ensure quality. 
6.2 
Randomization 
Randomization will only be done in the DB phase. Subjects will be centrally randomized in a 
blinded manner to placebo or seladelpar in a 1:2:2:2 scheme (placebo: seladelpar 10 mg: 20 mg: 
50 mg). In addition, randomized subjects will be stratified by diabetic status (yes/no) and fibrosis 
stage (Stage F1 vs. Stage F2-3). 
6.2.1 Randomization/Registration Procedure 
Once all laboratory, imaging evaluations and liver biopsy report are available and the subject has 
been confirmed to meet all the inclusion and none of the exclusion criteria, the subject will be 
invited to Day 1 visit (Baseline). Randomization will occur at Day 1 visit via a centrally 
administered Interactive X Response Technology System (IXRS) and dosing will be initiated. 
6.2.2 Emergency Unblinding 
In the event of a medical emergency, where knowledge of the subject’s treatment assignment is 
necessary per the medical judgment of the Investigator, the Investigator or the Sponsor can break 
the blind. The unblinding must be clearly justified and explained by a comment in the source

systems: general, skin, eyes, nose/sinuses, ears, mouth/throat, neck, breasts, and respiratory, 
cardiac, gastrointestinal, peripheral vascular, genitourinary, musculoskeletal, neurologic, mental 
health, endocrine and hematologic. 
Brief, symptom-directed physical examinations are allowed for Unscheduled visits in both study 
phases and for a condition that warrants the exam, as determined by the Investigator.  
Any clinically significant change in physical examination findings that occur after signing the ICF 
at the initial screening visit will be recorded as an AE.  
In the OLE phase, symptomatic-directed physical examinations will be performed at scheduled 
OLE clinic visits. 
In the SFU phase, complete physical examinations will include a full review of the following 
systems: general, skin, eyes, nose/sinuses, ears, mouth/throat, neck, breasts, and respiratory, 
cardiac, gastrointestinal, peripheral vascular, genitourinary, musculoskeletal, neurologic, mental 
health, endocrine and hematologic. 
7.4.2 Vital Signs and Weight/Height 
Vital sign measurements include temperature, heart rate, respiratory rate, and blood pressure, 
recorded in the sitting position after at least 5 minutes rest. Vital signs may be obtained more 
frequently if a condition develops that warrants additional monitoring. 
Height measurement will be performed at Baseline only; weight will be taken at each study visit 
per the Schedule of Assessments (Table 1 and Table 2). 
7.4.3 Electrocardiogram 
A 12-lead ECG will be obtained in supine position after at least 5 minutes of rest (DB phase only). 
7.4.4 Laboratory Tests  
Blood samples for laboratory testing will be collected after at least an 8-hour overnight fast and 
prior to dosing. If the subject forgets to fast, the site will continue to draw labs. Subjects should not 
be dosed with study drug until blood is collected. Additional details about sample collection, 
processing, handling and laboratory determination techniques are provided in the Laboratory 
Manual. If lab sample is not analyzable or reported for any reason, medical monitor will be

Hematology:  
Erythrocyte Count (RBC), Hemoglobin, Hematocrit, Leukocyte Count (white blood cell 
count [WBC]), WBC Differential (absolute and percentage), Platelets, PT/INR 
Exploratory Biochemistry: 
Fibrinogen, hs-CRP, ELF score, HA, PIII-NP, TIMP-1, C4, serum bile acids, FAO markers 
Back-Up Blood Sample:  
One of the blood samples collected at each study visit will be archived as a back-up sample. 
These samples can be stored for up to 5 years following completion of the study and used 
to measure drug levels, potential new biochemical markers, and/or to replace any missing 
or discarded samples.  
Serum Pregnancy Test: Serum pregnancy test in women of childbearing potential only.  
Hepatitis B and C Testing: At screening only. The tests will include HBsAg and HCV antibody 
and HCV RNA if HCV AB is positive. 
7.4.5 Liver Biopsy (DB and SFU Phases Only) 
A liver biopsy will be performed twice during the trial: during the screening period (Baseline liver 
biopsy), approximately Week 52 after the Baseline liver biopsy or after early termination visit (if 
withdrawn after Week 26 visit), and approximately 6 months after Week 52 or after early 
termination visit, in SFU phase for those subjects who have significant histological findings other 
than NASH (Table 3). 
Liver biopsy will be used to determine histological improvement in NASH and fibrosis. Liver 
biopsies will generally be obtained from the right lobe of the liver, however, if the Baseline biopsy 
is obtained from the left lobe, then the Week 52/ET liver biopsy must also be obtained from the 
left lobe. Biopsies should be performed using a 16G or larger biopsy instrument and samples should 
be at least 1.5 cm in length.  
Baseline Liver Biopsy: An eligible subject must have histological evidence of definite NASH on 
a liver biopsy and a NAS of 4 points or greater, with a score of at least 1 point in each component 
(steatosis, lobular inflammation, and ballooning). This will be used for enrollment into the DB 
phase. A new Baseline biopsy is not required for enrollment into the OLE phase. 
Subjects who meet all non-biopsy related inclusion criteria and none of the exclusion criteria will 
be invited to have a liver biopsy (if not already available as per Inclusion Criterion #3). If subjects 
had a liver biopsy done previously per standard of care but within 90 days prior to the initial 
screening visit, and if the pathology slides are available for review and of an adequate quality, the 
Baseline liver biopsy can be waived. 
Week 52/ET Liver Biopsy: The Week 52 and ET liver biopsy will be performed ± 1 week from 
the scheduled study visit.  
SFU Liver Biopsy: The SFU liver biopsy will be performed in eligible subjects at 6 months ±4 
weeks, from the Week 52/ET liver biopsy.

Page 53 of 77 
Pre-Liver Biopsy Instructions: The subject must have PT, INR and platelets performed with 
results available per the window specified by the local biopsy center. Subjects will be instructed, 
if possible, to fast 6 to 8 hours prior to the scheduled liver biopsy.  
Liver Biopsy Analysis: Central reader will review and analyze the tissue samples. The NAS and 
fibrosis score will be calculated using the NASH CRN criteria for the biopsies collected in the DB 
phase. The SFU biopsy will only be evaluated for persistence or resolution of the non-NASH 
significant histologic findings; NAS and fibrosis will not be scored on these samples. 
7.4.6 Imaging Tests  
7.4.6.1 MRE Exam (DB Phase Only) 
MRE exam will be used to evaluate liver fibrosis through a noninvasive imaging technique. As 
collagen deposition associated with fibrosis imparts parenchymal rigidity, the leading biomarker 
for assessing fibrosis is through elastography. MRE uses a modified phase-contrast pulse sequence 
to visualize rapidly propagating mechanical shear waves (typically delivered at around 60 Hz). 
Cross-sectional elastogram images will be created depicting the stiffness generated from the wave 
propagation information. Technically, elastography assessments can be accomplished with most 
magnetic resonance scanners by adding hardware to generate mechanical waves and adding 
specific software for acquisition and processing. Because the waves can be visualized and analyzed 
deep into the liver, MRE evaluates a large portion of the liver and can be performed in conjunction 
with conventional MRI. For these reasons, MRE is considered to be a reliable, highly accurate, and 
precise method for assessing hepatic fibrosis. 
Clinical sites will screen subjects for MRI safety and eligibility per institutional standards. 
MRE Exam Schedule and Timing: MRE will be performed at selected centers and only in the 
DB phase. Subjects will undergo two MRE exams. Clinical sites will determine the logistics of 
scheduling the MRE exam. 
• The first MRE exam will be performed during the screening period (prior to the invasive 
Baseline liver biopsy), as contemporaneously as possible to, and no more than 90 days from 
the Baseline liver biopsy  
• The second MRE exam will be performed as contemporaneously as possible to, and no 
more than 1 week before or after the Week 52/ET liver biopsy  
After completion of the exam, clinical sites will transfer MRE images to the Central MRI Reader.  
Pre-MRE Exam Instructions: Subjects will be instructed, if possible, to fast for 4 or more hours 
prior to the scheduled MRE exam but will be allowed to take necessary medications and small 
quantities of water. 
MRE Exam Analysis: Central MRI Reader will review and analyze images. The liver fibrosis 
(stiffness) will be calculated.  
7.4.6.2 MRI-PDFF Exam (DB Phase Only) 
MRI-PDFF exam will be used to quantify the hepatic proton density fat fraction noninvasively. 
The fat fraction is the proportion of mobile protons in liver tissue attributable to fat and thus, is a 
noninvasive magnetic resonance-based biomarker of liver triglyceride concentration. 


CymaBay Therapeutics, Inc 
Protocol CB8025-21730 
Protocol Version 3.0, 20-DEC-2019 
CONFIDENTIAL 
Page 54 of 77 
To quantify the fat fraction, the MRI-PDFF exam will use a fast spoiled gradient recalled echo 
(FSPGR) sequence that uses a low flip angle to reduce T1 bias, acquires multiple echoes after a 
single excitation to measure and correct for T2*decay, and uses spectral modeling to address fat-
water and fat-fat signal interference effects. Using MR spectroscopy as the reference standard, the 
proposed MRI technique measures hepatic fat fraction accurately in human subjects at 1.5T or 3T 
and across different vendors. The technique provides high within-examination and 
between-examination precision. Linearity is maintained across the entire relevant biological range 
from <1% to >40% hepatic fat fraction. The technique is robust to minor variations in acquisition 
parameters, including those that may be encountered during usage in a clinical trial. 
The FSPGR sequence proposed for imaging-based hepatic fat fraction quantification can be 
implemented on any up-to-date clinical scanner and can be used at clinical centers with access to 
such a scanner. Moreover, the technique is imaging based and covers the whole liver, thus 
providing information on both the quantity and distribution of hepatic fat fraction. These 
characteristics represent critical advantages over the alternative technique of single-voxel proton 
MR spectroscopy to measure hepatic fat fraction in a multicenter clinical trial.  
Clinical sites will screen subjects for MRI safety per institutional standards and will determine the 
logistics of scheduling the MRI-PDFF exam. 
MRI-PDFF Exam Schedule and Timing: Subjects will undergo four MRI-PDFF examinations 
in the DB phase only. The goal will be to schedule the second, third, and fourth MRI exams at the 
same or similar time of day as the first MRI-PDFF exam. 
• The first MRI-PDFF exam will be performed during the screening period prior to the 
Baseline liver biopsy but as contemporaneously as possible to and no more than 90 days 
from the Baseline liver biopsy  
• The second MRI-PDFF exam will be performed as close as possible to the Week 12 visit 
(±1 week from planned visit date) 
• The third MRI-PDFF exam will be performed as close as possible to the Week 26 visit 
(±1 week from planned visit date) 
• The fourth MRI-PDFF exam will be performed as contemporaneously as possible to and 
no more than 1 week before or after the Week 52/ET Visit (if applicable) 
Pre-MRI-PDFF Exam Instructions: Subjects will be instructed, if possible, to fast for 4 or more 
hours prior to the scheduled MRI-PDFF exam. However, they will be allowed to take necessary 
medications and small quantities of water. 
MRI-PDFF Exam Performance: Subjects will be positioned supine with a phased-array coil 
centered over the liver. After localizing sequences, an axial multi-echo-echo two dimensional 
FSPGR sequence will be performed through the liver. Imaging parameters will be selected as 
appropriate for 1.5T or 3T scanners. After completion of the exam, clinical sites will transfer MRI 
images to the Central MRI Reader.  
MRI-PDFF Exam Analysis: The Central MRI Reader will review and analyze images. The 
analysts will place 3 regions of interest on a PDFF image. The fat fraction will be calculated from 
all pixel values within the selected regions of interest and reported as the average value for each 
image.

7.4.6.3 FibroScan® Exam (DB and SFU Phases Only) 
FibroScan® exam will be used to evaluate liver fibrosis through a noninvasive imaging technique. 
FibroScan® uses a modified ultrasound probe to measure the velocity of a shear wave. Cross-
sectional elastogram images will be created depicting the stiffness generated from the wave 
propagation information. FibroScan® is considered to be a reliable, highly accurate, and precise 
method for assessing hepatic fibrosis. 
Clinical sites will screen subjects for FibroScan® safety per institutional standards. 
FibroScan® Exam Schedule and Timing: Subjects will undergo FibroScan® exams at centers 
when the test is available. Clinical sites will determine the logistics of scheduling the FibroScan® 
exam. 
• The first FibroScan® exam will be performed during the screening period prior to the 
Baseline liver biopsy  
• The second FibroScan® exam will be performed as closely as possible to Week 52/ (±1 
week from planned Week 52 visit date)/±1 week from ET visit date (if applicable) 
• FibroScan® exam will be performed in conjunction with each SFU biopsy 
Pre-FibroScan Exam Instructions: Subjects will be instructed, if possible, to fast for 4 or more 
hours prior to the scheduled FibroScan® exam but will be allowed to take necessary medications 
and small quantities of water. 
FibroScan Exam Analysis: Local Reader will review and analyze scans.  
7.4.6.4 LMS Exam (DB Phase Only) 
LMS is a noninvasive medical imaging software tool which, combined with MRI, can be a 
diagnostic tool to assess patients with liver disorders. The LMS provides quantitative measure of 
liver fat, and correlates iron and fibro-inflammation using multi-parametric MRI. The tool is U.S. 
FDA 510(k) cleared to aid clinicians in the diagnosis of liver disorders and abnormalities.  
Clinical sites will determine the logistics of scheduling the LMS exam and follow any additional 
provided guidelines on the use of this imaging software tool. Subjects will undergo 
4 LiverMultiScan examinations during the DB phase only. 
• LMS Exam Schedule and Timing: Subjects will undergo 4 LMS examinations  
• The first LMS exam will be performed during the screening period (prior to the Baseline 
liver biopsy), as contemporaneously as possible to and no more than 90 days from the 
Baseline liver biopsy  
• The second LMS exam will be performed as close as possible to the Week 12 visit (±1 week 
from planned visit date) 
• The third LMS exam will be performed as close as possible to the Week 26 visit (±1 week 
from planned visit date) 
• The fourth LMS exam will be performed as contemporaneously as possible to and no more 
than 1 week before or after the Week 52/ET Visit (if applicable)  
LMS Exam Analysis: The Central MRI Reader will review and analyze images.

ADVERSE EVENTS 
8.1 
General 
8.1.1 Definition of Adverse Events (AEs) 
An AE is any medical occurrence in a subject administered a pharmaceutical product in a clinical 
study, regardless of 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 product, whether or not related to the medicinal 
product. 
An AE includes any condition (including a pre-existing condition) that: 1) was not present prior to 
study treatment, but appeared or reappeared following initiation of study treatment, or 2) was 
present prior to study treatment, but worsened during study treatment. This would include any 
condition resulting from concomitant illnesses, reactions to concomitant medications, or 
progression of disease states. Pregnancy should be documented as an adverse event and should be 
reported to the clinical monitor and to the Sponsor immediately upon learning of the event. 
Pregnancies will be followed up through delivery or termination of the pregnancy. 
8.1.2 Definition of Serious AEs (SAEs) 
A serious adverse event (SAE) is any medical occurrence that: 
• Results in death 
• Is life-threatening (was at risk of death) at the time of the event  
• Requires in-patient hospitalization or prolongation of an existing hospitalization 
• Results in persistent or significant disability/incapacity defined as a substantial disruption 
of a person’s ability to conduct normal life functions 
• Is a congenital anomaly/birth defect 
• Is an important medical event that, when based upon appropriate medical judgment, may 
jeopardize the subject and may require medical or surgical intervention to prevent one of 
the outcomes listed above in the definition for an SAE. Examples of such events include 
allergic bronchospasm, requiring intensive treatment at an emergency room or at home, 
blood dyscrasias, convulsions that do not result in in-patient hospitalization, or the 
development of drug dependency or drug abuse 
8.1.3 AE Severity  
The severity of an AE will be graded from 1 to 5 according to Table 7 and CTCAE version 
4.0 criteria (Appendix C).   
The CTCAE general guideline will be used to assess AE severity. Not all Grades are appropriate 
for all AEs. Therefore, some AEs listed in the CTCAE have fewer than five options for Grade 
selection.

Table 7: 
Grading of AE Severity 
Grade 
Clinical Description 
Grade 1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated.  
Grade 2 
Moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate 
instrumental activities of daily living. 
Grade 3 
Severe or medically significant but not immediately life-threatening; hospitalization or 
prolongation of hospitalization indicated; disabling; limiting self-care activities of daily 
living.  
Grade 4 
Life-threatening consequences; urgent intervention indicated.  
Grade 5 
Death related to AE 
8.1.4 Adverse Event Outcome 
Subjects will be followed until AEs have either resolved, returned to baseline status, or are deemed 
stable or commensurate with ongoing disease processes, per the Investigational judgment. 
One of the four outcomes listed below must be recorded: 
Resolved – The subject has fully recovered from the event with no residual effects observable or 
returned to baseline status. 
Resolved with sequelae – The subject has recovered from the event with some residual effects 
observable. 
Ongoing – Effects of the event are still present, regardless of whether the effect is changing or 
stable and persistent. 
Fatal outcome (for serious adverse events only) 
8.1.5 Relationship to Treatment  
The relationship or association of the AE to a study treatment will be characterized as “unrelated”, 
“unlikely,” “possible,” “probably”, or “definite”, as shown in Table 88. 
Table 8: 
AE Relationship Attribution 
Relationship

8.1.6 Action Taken with Study Medication  
As a consequence of an AE, the action taken with study drug can be: 
• None: no changes were made to study drug administration or dose 


CymaBay Therapeutics, Inc 
Protocol CB8025-21730 
Protocol Version 3.0, 20-DEC-2019 
CONFIDENTIAL 
Page 58 of 77 
• Permanently discontinued: study drug was stopped and not restarted 
• Temporarily interrupted, restarted at the same dose: dosing was temporarily interrupted or 
delayed due to the AE and restarted at the same dose 
• Temporarily interrupted, restarted at a decreased dose: dosing was temporarily interrupted 
or delayed due to the AE and restarted at a decreased dose 
• Dose decreased: study drug dose was decreased without previous study drug interruption 
• Not applicable: e.g. in case the AE occurred after signing the ICF but before the 
administration of study drug was commenced 
8.2 
Recording, Reporting and Follow-Up of Adverse Events 
Details about the safety reporting process are presented in the Safety Reporting Plan. 
All AEs must be recorded by the Investigator in the eCRF, regardless of association with the use 
of the study treatment. An AE will be recorded any time after the time of signed ICF and captured 
until the last study visit.  
To avoid colloquial expressions, the AE should be reported in standard medical terminology. 
Whenever possible, the AE should be evaluated and reported as a diagnosis rather than as 
individual signs or symptoms. If a definitive diagnosis is not possible, the individual signs and 
symptoms should be recorded.  
For each AE, the Investigator or an adequately qualified designee will evaluate and report the onset, 
duration, severity, seriousness, and relationship to (association with) the study treatment, and 
indicate the action taken. 
Abnormal laboratory findings will be determined by review of all laboratory data collected on the 
subjects. At each visit, the Investigator is responsible for assuring that the subject is questioned 
regarding all potential AE and concurrent illnesses. 
Any laboratory abnormalities deemed clinically significant by the Investigator should be reported 
as an AE. A clinically significant abnormality is a confirmed abnormality that is changed 
sufficiently from baseline, so that in the judgment of the Investigator, a change in management is 
warranted. This alteration may include monitoring the laboratory test further, initiating other 
diagnostic tests or procedures, or administering treatment. Whenever possible, the etiology of the 
abnormal findings will be documented in the eCRF. Repeated, additional tests and/or other 
evaluations required to establish the significance and etiology of an abnormal result should be 
obtained when clinically indicated. 
Any clinically significant laboratory abnormalities that are either unexplained or considered 
treatment-related should be promptly reported to the Sponsor. Any additional relevant laboratory 
results obtained by the Investigator during this study will be supplied to the Sponsor and recorded 
in the eCRF. 
A change in diabetes medication dose may not be reported as an adverse event, however, 
Worsening of Diabetes from baseline must be documented as an adverse event during the course 
of study participation.

8.2.1 SAE Reporting Process 
The Sponsor or designee is responsible for regulatory submissions and reporting to the 
Investigators of SAEs including Suspected Unexpected Serious Adverse Reactions (SUSARs) per 
the International Conference on Harmonization (ICH) guidelines E2A and ICH E6, and per the 
United States Code of Federal Regulations (CFR); 21 CFR § 312.32. Country specific regulatory 
requirements will be followed in accordance with local country regulations and guidelines. 
Independent Ethics Committees will be notified of any SAE according to applicable regulations. 
Any SAE, including death due to any cause, that occurred from the signing of ICF through, 
regardless of relationship to the study treatment, must be reported immediately (no later than 
24 hours) by the Investigator to the Sponsor’s representative (safety vendor) using the SAE Report 
Form. Planned hospitalizations or procedures will not be considered as SAEs. 
The criteria for seriousness will be indicated on the SAE Report Form as follows: 
• Hospitalization or prolongation of hospitalization 
• Life threatening 
• Death 
• Persistent or significant disability/incapacity  
• Congenital anomaly 
• Other important medical events 
The outcome for the event will be listed on the SAE Report Form as follows: 
• Resolved 
• Resolved with sequelae 
• Ongoing 
• Fatal 
If additional information regarding a previously submitted SAE is obtained, a follow-up SAE must 
be sent to the Sponsor’s representative (safety vendor). 
The Sponsor and/or its designee will identify and report to regulatory authorities within the required 
timeframes, all serious and unexpected suspected adverse reactions (SUSARs) and clinically 
important increases in rate of serious suspected adverse reactions. 
SAEs must be collected and reported by the Investigator for the whole period from the signing of 
ICF until the last study visit. If the event of death occurs after the last study visit, the death will not 
have to be reported as an SAE.  
The Investigator will document all available information regarding the SAE on the standard form. 
The Investigator should not wait to receive additional information to fully document the event 
before notifying the Sponsor’s representative of an SAE. The initial notification should include, as 
a minimum, sufficient information to permit identification of: 
• Subject’s study number  
• Time and date of study drug administration 


CymaBay Therapeutics, Inc 
Protocol CB8025-21730 
Protocol Version 3.0, 20-DEC-2019

Page 60 of 77 
• Time and date of the start of the event and either the date and time of the resolution of the 
event or a statement that the event is ongoing  
• A brief description of the event and actions taken  
• Investigator’s opinion of the relationship of the event and the investigational product  
Follow-up report(s) should follow the initial report, using the SAE form detailing relevant aspects 
of the adverse events in question. Where applicable, information from relevant hospital case 
records and autopsy reports should be obtained. All source information provided to the Sponsor 
must be appropriately anonymized.   
8.2.2 Follow-up of Reported AEs  
SAEs recorded during the study will be followed by the Investigator until resolution or 
stabilization. 
After the Post-Treatment Visit, non-serious AEs should be followed up until they resolve or have 
failed to resolve, for a duration determined by the Investigator.  
Follow-up procedures will be determined by the nature of the event and the judgment of the 
Investigator. 
8.3

8.5 
Precautions 
8.5.1 Pregnancy 
No specific studies have been performed to determine the reproductive and developmental toxicity 
of seladelpar.  
As a precaution, women of childbearing potential participating in this study must use one barrier 
contraceptive and a second effective birth control method during the study and for at least 30 days 
after the last dose. Male subjects who are sexually active with female partners of reproductive 
potential must use barrier contraception and their female partners must use a second effective birth 
control method during the study and for at least 90 days after the last dose of study drug. Sexual 
abstinence, defined as refraining from heterosexual intercourse during the entire period of risk 
associated with the study treatments, is acceptable as an effective birth control method. The 
reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial 
and the preferred and usual lifestyle of the subject. 
A second effective birth control method includes the following:  
• Combined (estrogen- and progestogen-containing) hormonal contraception associated with 
inhibition of ovulation:

• intravaginal 
• transdermal 
• Progestogen-only hormonal contraception associated with inhibition of ovulation: 
• oral 
• injectable 
• implantable 
• Intrauterine device (IUD)  
• Intrauterine hormone-releasing system (IUS)  
• Bilateral tubal occlusion  
• Vasectomized partner 
8.6 
Study Stopping Rules 
If any of the three criteria below are met and adverse events are considered related to study drug, 
the study must be stopped:  
• Three participants develop the same Grade 3 CTCAE related to study drug,   
• Two participants develop any Grade 4 CTCAE related to study drug, or 
• One participant develops a Grade 5 CTCAE

DATA MANAGEMENT AND STATISTICAL ANALYSES 
10.1 
Data Management 
10.1.1 Processing of Electronic Case Report Forms  
Electronic CRFs (eCRFs) will be completed for all study subjects enrolled in the study. At 
scheduled monitoring visits, eCRFs will be verified against source documentation. Upon 
completion of this review, finalized eCRFs will be submitted to the Sponsor’s designated Contract 
Research Organization (CRO). Any subsequent changes to the eCRFs will be performed in 
accordance with the CRO’s Standard Operating Procedures (SOP) for editing and clarifying 
eCRFs. 
10.1.2 Database  
Data entry will be performed through username and password-protected access to a secure 
database. All data will be entered using electronic eCRFs. Internally developed programs for 
plausibility, consistency, and out-of-range data fields will supplement the review of the data. A 
100% manual review of AEs, drug accountability and termination summary data, will be performed 
by Data Management personnel. The Medical Dictionary for Regulatory Activities (MedDRA) 
coding thesaurus will be used to classify AEs, medical history and concomitant procedures while 
the World Health Organization (WHO) Drug classification will be used to code medications. 
10.1.3 Data Discrepancies 
After all subjects complete the study and data discrepancies are resolved, protocol deviations 
during both enrollment and study execution will be reviewed. Significant protocol deviations and 
procedural discrepancies will be discussed. All data will be included in the safety analyses. 
10.2 
Statistical Analysis 
Full details on the statistical methodology to be used will be included in a SAP to be developed 
prior to study unblinding. 
10.2.1 Sample Size Estimation  
A sample size of 175 subjects (50 subjects per each dose of seladelpar and 25 subjects for placebo) 
provides at least 80% power to detect a pairwise treatment difference of at least 20% between the 
active and placebo groups with respect to a relative change from baseline in hepatic fat fraction, as 
assessed by MRI-PDFF at Week 12. Power calculations were performed using a standard t-test, 
allowed for a 12% dropout rate (6 subjects per seladelpar arm, 3 subjects for the placebo arm), and 
a pooled standard deviation of 26 for the relative change endpoint.  
10.2.2 Analysis Populations 
The safety analysis will be conducted on the Safety Population. Efficacy analyses will be conducted 
on the intent-to-treat (ITT) population, the modified intent-to-treat (mITT) population, the 
modified intent-to-treatment population with biopsy (mITTb), and the per-protocol (PP) 
populations. The mITT population will be used for the primary efficacy analysis.

10.2.2.4 
Modified Intent-to-Treat Population with Biopsy (mITTb)  
The mITTb population is defined as any subject who is randomized, receives at least one dose of 
study drug, and has Baseline and Week 52/ET liver biopsies.  
10.2.2.5 
Per-protocol population (PP)  
The PP population is defined as any subject who is randomized and receives at least one dose of 
study drug, has Baseline and Week 52/ET liver biopsies, and does not have a protocol violation that 
is deemed to impact the efficacy analysis.  
10.2.3 Demographics and Baseline Characteristics  
Demographic and baseline characteristics (medical histories, physical examinations, and 
concomitant medications) will be summarized using descriptive statistics (mean, standard 
deviation, median, minimum and maximum) for continuous variables and frequency distributions 
(counts and percentages) for discrete variables. 
10.2.4 Efficacy Analysis 
10.2.4.1 
Primary Efficacy Analysis  
Pairwise comparisons between each dose of seladelpar versus placebo with respect to the relative 
change in hepatic fat fraction as assessed by MRI-PDFF at Week 12 will be conducted using 
ANCOVA. The LS means, standard errors, 95% CIs, and p-values will be provided from the 
ANCOVA model with percent change from baseline in MRI-PDFF as the dependent variable, 
treatment group, diabetic status, and fibrosis stage as factors and baseline MRI-PDFF as covariates. 
Relative change will be calculated as  
[MRI-PDFFWEEK12 – MRI- PDFFBASELINE] ×100 / MRI-PDFFBASELINE. 
All statistical comparisons will be made at a two-sided alpha of 0.05.  
Other analyses will be secondary. 
In primary, mITT analyses, subjects with missing efficacy data will be considered unimproved on 
the primary outcome measure.

The safety measures will be incidence rate of AEs and TEAEs, ECG, biochemistry, hematology 
and urinalysis, physical exams and vital signs as measured by NCI CTCAE Version 4.0. 
Safety data will be summarized by study treatment (placebo vs. seladelpar) and by seladelpar dose 
administered during the treatment period for the DB, OLE and SFU phases. Baseline values in the 
DB and OLE phases for laboratory tests, vital signs, and electrocardiograms will be defined as the 
last evaluation performed prior to administration of study drug. Baseline values in the SFU phase 
for laboratory tests, vital signs, and electrocardiograms will be defined as the last evaluation prior 
to obtaining informed consent for the SFU phase. 
10.2.5.1 
Adverse Events 
The subset of AEs occurring after the first dose of study drug will be considered to be TEAEs in 
the DB and OLE phases. The incidence of TEAEs will be tabulated. All AEs will be reported and 
tabulated for the SFU phase; there is no TEAE subset for this study phase. 
10.2.5.2 
Vital Signs 
Descriptive statistics and mean or median change from baseline will be determined for vital signs 
(temperature, heart rate, respiratory rate, blood pressure) at each assessment. Vital signs collected 
at all study time points will be recorded in the eCRF and analyzed or listed. 
10.2.5.3 
Physical Examination 
Clinically significant abnormalities on physical examination will be recorded as AEs in the eCRF. 
10.2.5.4 
Laboratory Tests 
Descriptive statistics for the result and change from baseline will be summarized for each 
laboratory test by study treatment and visit. Abnormal laboratory values will be graded by the 
investigator as “clinically significant” or “not clinically significant”, where applicable. Clinically 
significant abnormal laboratory values will be reported as AEs, after study treatment has been 
initiated. Investigators may repeat laboratory tests for any parameter that is abnormal and/or 
clinically significant. 
10.2.5.5 
Electrocardiograms 
Clinically significant abnormalities on ECGs will be recorded as AEs in the eCRF. Summaries of 
ECG parameters by study treatment and visit will be prepared.  
10.2.5.6

INTRODUCTION 
This document provides a description of the statistical methods and procedures to be implemented 
for the analyses of data from the study with protocol number CB8025-21730.  Any deviations from 
this Statistical Analysis Plan (SAP) will be documented in the final clinical study report. 
1.1 
Study Termination 
On November 25, 2019, CymaBay Therapeutics announced that the company was terminating the 
study. The decision to terminate that study based on atypical histological findings observed in the 
first 86 centrally read, end of treatment biopsies from study subjects.  Planned, blinded histological 
assessments of the first tranche of liver biopsies in the trial revealed atypical histological findings, 
including histology characterized as an interface hepatitis presentation, with or without biliary 
injury.   
At the time of study termination, 181 subjects were randomized and enrollment had been closed. 
Eleven subjects had been dosed in the open-label extension (OLE) phase under protocol V2.0 (13-
SEP-2019). Week 12 topline primary efficacy analysis was conducted per protocol, after a 
database freeze of the necessary electronic case report forms and prior to study cancellation and 
unblinding, in June 2019.  
In order to protect patient safety, and aid further investigation to better understand the findings 
leading to study termination, the study was unblinded December 11, 2020 prior to database lock 
of the double-blind (DB) and OLE phases of the study. There will be two database locks: the first 
for the DB and OLE phases of the study, and the second after the completion of the safety follow-
up (SFU) phase. This SAP describes analyses for DB, OLE, and SFU phases, and will be finalized 
prior to the main study DB database lock (DB and OLE phases) and the analyses will be conducted 
after the respective database lock.

in subjects with significant histologic findings on the Week 52 or Early Termination (ET) 
liver biopsy 
2.2 
Study Design 
DB Phase 
This phase of the study is designed as a dosing ranging proof-of-concept study to evaluate the 
safety and potential efficacy effects of seladelpar on MRI-PDFF. The study includes liver biopsies 
to confirm that subjects have histological evidence of NASH at screening and to evaluate 
histological improvement in NASH and fibrosis after 52 weeks of treatment. 
The study is planning to enroll approximately 175 male and female subjects. Subjects will be 
randomly assigned to receive placebo, seladelpar 10 mg/day, seladelpar 20 mg/day or seladelpar 
50 mg/day (1:2:2:2 ratio). Subjects will be stratified by diabetic status (yes/no) and fibrosis stage 
(F1 versus F2-3). Study drug (placebo or seladelpar) will be taken in a blinded manner orally once 
a day for a period of 52 weeks. 
The screening period will be up to 10 weeks, the blinded treatment period will be up to 52 weeks, 
and a follow-up period of 4 weeks after the last dose of study drug (i.e. Week 56). During the 
treatment period, the first on-treatment visit will occur 4 weeks after initiation of the study drug. 
Subjects will then be evaluated in clinic every 4 weeks until Week 12. After Week 12, visits will 
be 6-7 weeks apart. Subjects will also be contacted by phone or email at Weeks 19, 32 and 45. The 
amount of fat in the liver will be evaluated by MRI-PDFF at baseline, Weeks 12, 26, and 52. A 
liver biopsy will be performed twice during the DB phase: at baseline and at Week 52. 
The primary efficacy analysis will be the change from baseline to Week 12 in MRI-PDFF. The 
study will continue in a blinded fashion until the Week 52 biopsy is collected. 
The schedule of assessments for the DB phase can be found in Protocol Table 1. 
OLE Phase 
All subjects who participate in the DB phase, complete the 52-week biopsy and the 56-week 
follow-up labs, and meet the specified enrollment criteria will be offered participation in the OLE 
phase of the study. Subjects will not be required to have any additional liver histology, imaging or 
elastography assessments for enrollment or on-treatment assessments of treatment effect. The OLE 
Day 1 visit may be combined with the Week 56 visit in the DB phase. Informed Consent may 
occur at Week 52 or Week 56 in the DB phase for subjects still active in the DB phase or any time 
prior to any OLE procedures in patients who have completed the DB phase. Eligibility assessment

may occur on or after the Week 56 in the DB phase. Laboratory assessment for OLE suitability 
may be required if more than 45 days have elapsed since last lab collection to anticipated first OLE 
dosing. If greater than 45 days have elapsed since the last lab collection, subjects must complete 
an unscheduled visit where all labs collected at Week 56 will be retested. Subjects must also be 
clinically stable based on the investigator’s medical judgement and key enrollment criteria to enter 
the OLE. All eligible subjects will receive seladelpar 50 mg regardless of dose received during the 
DB phase. Clinic visits during the 52-week OLE phase will occur at Day 1 and Weeks 2, 13, 26, 
39 and 52 with a final EOS visit at approximately Week 56 visit. The primary objective of the 
OLE phase is to assess long-term safety and treatment effect as measured by biochemical tests 
after an additional 52 weeks of treatment. 
The schedule of assessments for the OLE phase can be found in Protocol Table 2. 
SFU Phase 
All subjects who participated in the DB phase that have significant histologic findings other than 
NASH on the Week 52 or ET liver biopsy and received active seladelpar for at least 6 months will 
be asked to enroll in the SFU phase. Subjects in the placebo dosing group will not be enrolled into 
the SFU phase. After informed consent is obtained, an SFU visit will be performed at a minimum 
of 6 months after the Week 52 or ET liver biopsy. A repeat liver biopsy will be obtained to reassess 
the status of the original significant histologic findings. Other study procedures performed during 
the visit include a physical exam, vital signs, safety laboratory assessments, exploratory liver 
injury biomarker assessments, and FibroScan. Subjects with resolution or stabilization of the 
observed histologic findings will have completed the SFU phase, and no further visits or 
assessments will be required. Subjects worsening of the observed histologic findings will be 
followed up by phone at 3-month intervals and may be requested to have additional SFU visits 
with a repeat of some or all of the above procedures. 
2.3 
Study Outcome Measures 
2.3.1 Efficacy Outcome Measures 
The primary efficacy outcome measure is the relative change (i.e. percent change) in MRI-PDFF 
at Week 12 in the DB phase. 
The secondary efficacy outcome measures related with MRI-PDFF are: 
 observed change in MRI-PDFF at Weeks 12, 26, and 52 in the DB phase; 
 relative change (i.e. percent change) in MRI-PDFF at Weeks 26 and 52 in the DB phase; 
and 
 proportion of subjects with a relative decrease in MRI-PDFF ≥ 30% (i.e. percent change 
≤ -30%) at Weeks 12, 26, and 52 in the DB phase. 
 proportion of subjects with an observed MRI-PDFF change ≥ 5% (reduction, i.e. change 
≤ -5%) at Weeks 12, 26, and 52 in the DB phase.

Page 10 of 22 
 
The secondary efficacy outcome measures related with liver biopsy include the following: 
 proportion of subjects with reversal of NASH and no worsening of hepatic fibrosis 
(centrally scored histology at 52 weeks) in the DB phase. The reversal of NASH is defined 
as the absence of hepatocellular ballooning (score of 0) and no or minimal inflammation 
(lobular inflammation score of 0 or 1);  
 proportion of subjects with improvement by at least one stage in fibrosis without worsening 
of NASH (i.e. improvement by at least one fibrosis stage without worsening of NAFLD 
activity score) in the DB phase; and 
 proportion of subjects with a ≥ 2-point improvement in NAS in the DB phase. 
Other secondary efficacy outcome measures include the following: 
 relative (percent) and observed change in alanine aminotransferase (ALT), AST, gamma-
glutamyl transferase (GGT) in the DB and OLE phases;  
 relative (percent) and observed change in total cholesterol (TC), high-density lipoprotein 
cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), non-high-density 
lipoprotein cholesterol (non-HDL), homeostatic model assessment of insulin resistance 
(HOMA-IR) in the DB and OLE phases; and 
 relative (percent) and observed change in high-sensitivity C-reactive protein (hs-CRP) in 
the DB and OLE phases. 
The exploratory efficacy variables include the following:  
 MRE changes at Week 52 in the DB phase; and 
 LiverMultiScan (iron corrected T1 – cT1) changes at Weeks 12, 26, and 52 in the DB phase. 
2.3.2 Safety Outcome Measures 
The primary safety outcome measures include adverse events (AEs) and treatment emergent 
adverse events (TEAEs), physical exams, vital signs, electrocardiograms (ECGs), biochemistry, 
and hematology (National Cancer Institute Common Terminology Criteria for Adverse Events 
[NCI CTCAE], Version 5.0) and pre-defined laboratory changes of interest. 
3. 
STATISTICAL METHODOLOGY 
3.1 
Baseline, Endpoint, and Other Statistical Considerations 
Unless otherwise stated, only data collected during the DB phase will be summarized. Data 
collected during the OLE and SFU phases will be listed only.  
Baseline Definition 
Baseline for the DB phase for all efficacy and safety variables will be defined as the last scheduled 
value obtained prior to the first dose of study drug. If the measurement at this visit is missing, the 
last measurement prior to the first dose of study drug will be used as baseline. The scheduled 
baseline visit for MRI-PDFF, FibroScan, LiverMultiScan, MRE, and liver biopsy is Screening. 
For all other efficacy and safety variables, the scheduled baseline visit is Day 1 pre-dose.

3.2 
Analysis Populations 
The safety analysis will be conducted on the Safety Population. In the event of treatment allocation 
errors, subjects will be analyzed for safety according to the treatment they received. Efficacy 
analyses will be conducted on the Intent-to-Treat (ITT) Population, the Modified Intent-to-Treat 
(mITT) Population, and the Modified Intent-to-Treat Population with biopsy (mITTb). In the event 
of treatment allocation errors, subjects will be analyzed for efficacy according to the treatment to 
which they were randomized. The mITT Population will be used for the primary efficacy analysis. 
All analyses except MRI-PDFF will be repeated on the following subgroups: 
 Subjects in the mITTb Population with atypical biopsy findings at Week 52/ET 
 Subjects in the mITTb Population without atypical biopsy findings at Week 52/ET 
3.2.1 Safety Population 
The Safety Population is defined as any subject who receives at least one dose of study drug.  
3.2.2 Intent-to-Treat Population 
The ITT Population is defined as any subject who is randomized and receives at least one dose of 
study drug.  
3.2.3 Modified Intent-to-Treat Population 
The mITT Population is defined as any subject who is randomized, receives at least one dose of 
study drug, and has Baseline and Week 12 MRI-PDFF.  
3.2.4  Modified Intent-to-Treat Population with Biopsy 
The mITTb Population is defined as any subject who is randomized, receives at least one dose of 
study drug, and has Baseline and Week 52/ET liver biopsies.  
3.3 
Subject Disposition 
The reason given for each screen failure will be listed. Subject disposition will be provided for all 
randomized subjects. The number and percentage of subjects in each of the following disposition 
categories will be presented: 
 Subjects who are randomized, 
 Subjects in each analysis population including the biopsy subgroups,  
 Subjects who complete Week 12, 
 Subjects who complete the DB phase of the study,  
 Subjects who withdraw from the DB phase of the study, 
 Subject who dose in the OLE, 
 Subjects who complete the OLE phase of the study,  
 Subjects who withdraw from the OLE phase of the study, and 
 Subjects entering the SFU phase (i.e. subjects that received seladelpar and had atypical 
biopsy findings at Week 52/ET). 
For randomized subjects who withdraw from the study, the primary reason for the withdrawal will 
be listed and summarized. For any subject that withdrawal on or after November 25, 2019, the 
reason for withdrawal will be “study cancelled by Sponsor.”

Demographics and Baseline Characteristics 
Demographics (age, sex, race, and ethnicity), body weight, height, body mass index (BMI), HbA1c, 
hs-CRP, and stratification groups (diabetic status and fibrosis stage) will be summarized by 
randomized treatment using descriptive statistics for the Safety Population and repeated for each 
mITT Population, mITTb Population, and biopsy subgroups. 
Baseline MRI-PDFF, liver enzymes (ALT, AST, GGT), fibrosis stage, NAS, LiverMultiScan, and 
MRE, FibroScan, TC, LDL-C, HDL-C, triglycerides, HbA1c, and HOMA-IR will also be 
summarized for disease characteristics. 
Medical history will be coded using the Medical Dictionary for Regulatory Activities (MedDRA) 
V20.1.  The number and percentage of subjects with medical history will be summarized by 
preferred term within system organ class and by treatment group. 
Alcohol consumption collected at screening will be listed. 
3.5 
Prior/Concomitant Medications 
The use of any prior medication or concomitant medication will be listed for all subjects. 
Medications will be coded using World Health Organization (WHO) Drug Dictionary September 
2017G B3 version. The number and percentage of subjects taking concomitant medications will 
be summarized by preferred term within anatomical therapeutic chemical (ATC) term and by 
treatment group for the Safety Population, mITT Population, mITTb Population, and biopsy 
subgroups.  
A concomitant medication in the DB phase is defined as any medication taken on or after the first 
dose of study drug in the DB phase (includes those that began prior to study drug dosing but were 
ongoing or ended on or after the first dose of study drug). Medications that start on or after the 
first dose of study drug in the OLE phase are excluded. 
Concomitant procedures will be listed. 
3.6 
Study Drug Exposure and Compliance 
Days of overall exposure to study drug in the DB phase will be summarized by treatment group 
for the Safety Population, mITT Population, mITTb Population, and biopsy subgroups using 
descriptive statistics. Exposure in days is defined as: 
date of last dose of study drug – date of first dose + 1 
If the date of last dose of study drug from the DB phase end of study electronic case report form 
(eCRF) is unknown, it will be imputed based on the following priorities if available for the subject: 
1. If day is unknown but month and year are known, the last day of the month will be used 
2. Day prior to Week 52/End of Treatment Visit from the “date of visit” eCRF 
3. Day prior to Early Termination Visit from the “date of visit” eCRF 
4. Day of study completion/early termination from the DB phase end of study eCRF 
5. Last available visit date from the “date of visit” eCRF

If bottles were dispensed but not returned, 0 returned tablets will be assumed in the calculation (i.e. 
this assumes all tablets were used). Percent compliance with the study drug during the 12-week 
treatment period in the DB phase and the whole 52-week treatment DB period will be summarized 
by treatment group for the Safety Population, mITT Population, mITTb Population, and biopsy 
subgroups using descriptive statistics. Additionally the number and percentage of subjects within 
each treatment group with overall compliance in the following categories will be provided: <80%, 
80% to 120%, and >120%. 
Study drug interruptions and planned dose changed will be listed but will not be factored into the 
compliance calculation.

Analysis of Efficacy 
3.7.1 Descriptive Statistics 
All data will be listed for the randomized subjects. Descriptive statistics of the baseline, change 
from baseline and/or relative (percent) change from baseline to each post-baseline visit will be 
presented by treatment group for each efficacy measurement. 
3.7.2 Analyses of Hepatic Fat Fraction by MRI-PDFF 
Summary statistics (number of subjects, mean, standard deviation, median, minimum, and 
maximum) for MRI-PDFF at all visits and the change and relative (percent) change from baseline 
will be provided for the ITT and mITT Population. 
3.7.2.1 Primary Efficacy Analysis 
The primary efficacy outcome measure is the relative change (i.e. percent change) in MRI-PDFF 
at Week 12. 
Relative (percent) change in MRI-PDFF = 100 × (Week 12 – Baseline) / Baseline. 
An analysis will be performed on the relative (percent) change from baseline to Week 12 in 
MRI-PDFF using analysis of covariance (ANCOVA) model with treatment and stratification 
groups (diabetic status and fibrosis stage) as factors and baseline MRI-PDFF as a covariate using 
the mITT Population and repeated based on the PP Population with MRI-PDFF. The LS means, 
standard errors, 95% confidence intervals (CIs), and p-values will be provided. All statistical 
comparisons will be made at a two-sided alpha of 0.05. Adjusting for multiplicity, treatment

comparisons of the primary efficacy endpoint will be tested using a hierarchical “fixed-sequence” 
approach to assess clinical benefit of each of the seladelpar dose levels versus placebo, starting 
first with the 50 mg dose at a 5% alpha level. If positive, the seladelpar 20 mg dose will be 
compared to placebo at a 5% alpha level. If both seladelpar 50 mg and 20 mg doses are statistically 
superior to placebo then the testing will continue to the 10 mg dose vs placebo. Regardless of 
significance level achieved, p-values will be presented in the summary tables for informational 
purposes but claims of statistical significance will not be made unless the rules of the hierarchical 
testing approach are achieved.

transformed data, and the results will be back-transformed to relative (percent) change. If the 
residuals of this transformed model are still not normal, then non-parametric analyses will be 
explored. 
3.7.2.2 Hepatic Fat Fraction Treatment Goals 
The secondary efficacy outcome measures related to MRI-PDFF treatment goals are: 
 proportion of subjects with a relative decrease in MRI-PDFF ≥ 30% (i.e. percent change 
≤ -30%) at Weeks 12, 26, and 52; 
 proportion of subjects with an observed MRI-PDFF change ≥ 5% (reduction, i.e. change 
≤ -5%) at Weeks 12, 26, and 52. 
For each endpoint, the number and percentage of responders will be provided by treatment group 
and by stratification group. Cochran-Mantel-Haenszel tests will be performed adjusting for 
stratification groups (diabetic status and fibrosis stage). The general association p-value will be 
provided. Then for each seladelpar treatment group compared to placebo, the odds ratio, 95% 
confidence interval, and Breslow-Day test for homogeneity of the odds ratio p-value will be 
provided. The analysis will be performed on the ITT Population and repeated for the mITT 
Population. Subjects with missing data will be considered unimproved on the outcome measure.

provided. Subjects with missing data will be considered unimproved on the outcome measure.  
3.7.4 Analyses of Other Efficacy Endpoints 
All endpoints will be summarized and analyzed based on the ITT Population and repeated on the 
mITTb Population and biopsy subgroups. Since these endpoints are for exploratory purposes, no 
adjustments for multiplicity will be made. Summaries will exclude OLE phase visits. All OLE data 
will be listed.

temporally associated with the use of a medicinal product, whether or not related to the medicinal 
product.  
For analysis, a TEAE is defined as any AE that occurred after the first dose of double-blind study 
drug and up to 30 days after last dose of double-blind study drug, or one day before the first dose 
of OLE phase, whichever is earlier.  
Only AEs in the DB phase will be included in the summary tables. AEs beginning after the first 
dose of the OLE phase will be excluded from summaries but will be included in listings. 
A summary overview of TEAEs will be provided, which presents the number and percentage of 
subjects in each treatment group from the Safety Population, including number of events, 
satisfying each of the following categories: 
 Any TEAEs, 
 Maximum severity of TEAEs, 
 Study drug-related TEAEs, 
 Maximum severity of study drug-related TEAEs, 
 All serious AEs (SAEs), 
 All study drug-related SAEs, 
 AEs leading to death, 
 AEs leading to dose decreased or temporary interruption, 
 AEs leading to study drug discontinuation, and 
 Study drug-related AEs leading to study drug discontinuation. 
Adverse events will be coded using MedDRA. The number and percentage of subjects with 
TEAEs, including the number of TEAEs, will be summarized by their MedDRA preferred term 
within system organ class and by treatment.  For subject count summaries, multiple AE events 
with the same MedDRA coded terms (preferred term and system organ class) from the same 
subject will only be counted once. Similar summaries will be provided for drug-related TEAEs. 
The number and percentage of subjects with TEAEs will be summarized by reported maximum 
severity within each MedDRA preferred term within system organ class and by treatment.  Similar 
summaries will be provided for SAEs, for drug-related TEAEs, and for TEAEs beginning in the

After the final database lock, the study data listings will be updated to include all data that is 
collected during the SFU phase. Summary of baseline characteristics, demographics and safety 
data of subjects who participate SFU phase may be summarized if applicable.   
4. 
SAMPLE SIZE DETERMINATION 
A sample size of 175 subjects (50 subjects per each dose of seladelpar and 25 subjects for placebo) 
provides at least 80% power to detect a pairwise treatment difference of at least 20% between the 
active and placebo groups with respect to a relative change from baseline in hepatic fat fraction, 
as assessed by MRI-PDFF at Week 12. Power calculations were performed using a standard t-test, 
allowed for a 12% dropout rate (6 subjects per seladelpar arm, 3 subjects for the placebo arm), and 
a pooled standard deviation of 26 for the relative change endpoint. 
5. 
CHANGES FROM PROTOCOL 
The Protocol specified use of NCI CTCAE version 4.0. However, version 5.0 has become available 
and will be used for summaries.  
Due to the early termination of the study, the following will not be analyzed: 
 MMRM and Wilcoxon rank-sum analysis of MRI-PDFF 
 proportion of subjects with normalization of MRI-PDFF (defined as a fat fraction of < 5%) 
at Weeks 12, 26, and 52 in the DB phase 
 CMH analysis of biopsy endpoints 
 Summaries of APRI and FIB-4 in the DB and OLE phases (all reported data will still be 
listed) 
 Summaries of fibrinogen in the DB and OLE phases (all reported data will still be listed)
