Outline
It was previously stated that key 
eligibility criteria had to be evaluated
prior to liver biopsy at screening. 
This was changed to state that it was 
recommended. 
Updated to give the sites more 
flexibility.
Table 1: Screening Procedural 
Outline
Clarification that FSH assessment is 
only required to confirm menopause 
in women <55 years old.

Description of Change
Brief Rationale
Table 1: Screening Procedural 
Outline
HbA1c was added to screening 
procedures.
HbA1c at Screening is one of the 
exclusionary laboratory assessments 
described in Section 9.4.1, Table 8. It 
has been added to Table 1 (Screening 
Procedures Outline) for consistency.
Table 2: Treatment Period 
Procedural Outline
Added that liver biopsy should be 
performed within ±3 days of the visit 
window for Wk12 and ETT visits, 
and that 4 additional days are 
allowed with Medical Monitor 
approval.
Updated for clarification.
Table 3: Follow-up Period 
Procedural Outline
 
 
Updated for clarification.
Section 3.2.2: Clinical Studies
Added study results from IM025015 
which has been completed.
Updated based on new data available.
Section 3.3.2: Coronavirus 
Disease 2019-Related and 
Section 7.7: Concomitant 
Therapy
Non-live COVID-19 vaccinations are 
allowed during the study, and should 
follow local standard practices. 
Benefit-risk section updated to 
include the sentence that the efficacy 
and safety of COVID-19 virus 
vaccines in patients using 
BMS-986263 is unknown at the 
moment.
Updated to align with BMS COVID-
19 guidance.
Section 5.1.1: Screening Period
Medical Monitor approval is no
longer required for the extension of 
screening period.
To decrease the sites burden. the 
Medical Monitor approval 
requirement was removed; allowing
the sites to extend the screening 
period up to 4 weeks if necessary,
without needing to contact the 
Medical Monitor.
Section 6.1: Inclusion Criteria
and Section 9.1.2: Liver Biopsy 
Assessments
Liver biopsy performed prior to 
screening was extended from 6 to 12 
months. Additionally NASH criteria 
could be fulfilled using biopsies of 
12 months instead of 6 months.
Updated to allow patients with 
historical biopsy 6 to 12 months prior 
to screening to enroll to the study. 
The study population patients with 
cirrhosis (Stage 4 fibrosis) have slow 
disease progression.

Language clarified.
Updated to clarify who and how the 
DXA assessment will be analyzed. 
Section 6.1: Inclusion Criteria
Stable dose of treatment 
requirements was updated to 3 
months prior to screening.
Updated due to extension of 
historical biopsy to 12 months and 
requirement for stable dose to 15 
months prior to screening will be 
very difficult.
Section 6.2: Exclusion Criteria
and Section 8.1: Discontinuation 
from Study Treatment
Planned liver transplantation changed 
to planned during the study.
Updated to clarify timeframes of 
unacceptable liver transplantation. 
Section 6.2: Exclusion Criteria
Removed required discussion with 
Medical Monitor related to MELD 
and Child-Pugh Score criteria.
Updated to align with local UK 
amendment, and to provide more 
objective guidance for investigators 
to make the eligibility determination 
of participants with Gilbert syndrome 
whose MELD and Child-Pugh Scores 
are elevated due to a benign cause of 
unconjugated hyperbilirubinemia 
without requiring consultation with 
the Medical Monitor.
Section 6.2: Exclusion Criteria
Clarification added that both serum 
AFP and historical CT/MRI will be 
required for Screening. and if either 
of the results meets the criteria the 
participant will be excluded from 
study.

timeframes for screening after 
COVID depending on the severity of 
the previous infection.
Section 6.2: Exclusion Criteria
History of significant weight 
gain/loss relative to the timing of the 
liver biopsy was removed, and any 
significant weight changes was 
updated to within 3 months of 
screening.
Removed due to extension of 
historical biopsy to 12 months and 
requirement for stable weight up to 
15 months prior to screening will be 
very difficult.
Section 6.2: Exclusion Criteria
Exclusion criteria updates so that 
vaccines approved by regulatory 
agencies other than the United States
Food and Drug Administration may 
also be considered for inclusion.
Updated to allow vaccines approved 
by other regulatory agencies.
Section 6.2: Exclusion Criteria
Exclusion criteria for laboratory 
results were updated that HbA1c 
could not be ≥ 9.5% instead of 9.0%.

PROTOCOL SUMMARY

Synopsis
Protocol Title: A Randomized, Double-blind, Placebo-controlled, Parallel-group, Multiple-dose 
Phase 2 Study to Evaluate the Efficacy and Safety of BMS-986263 in Adults with Compensated 
Cirrhosis from Nonalcoholic Steatohepatitis (NASH)
Short Title: Efficacy and Safety of BMS-986263 in Adults with Compensated Cirrhosis from 
NASH
Study Phase: 2
Rationale: Study IM025017 aims to demonstrate the antifibrotic efficacy of BMS-986263, using 
a liver fibrosis histological endpoint, and the safety and tolerability of BMS-986263, as assessed 
by adverse events (AEs), serious adverse events (SAEs), laboratory results (including assessment 
of potential drug-induced liver injury), vital signs, physical examinations, electrocardiograms 
(ECGs),
 infusion-related reaction monitoring, and bone mineral 
density (BMD) monitoring, in participants with nonalcoholic steatohepatitis (NASH) and 
compensated cirrhosis.
Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver 
disease in the world today. NASH, which is the more advanced form of NAFLD, is defined as the 
presence of hepatic steatosis and inflammation with hepatocyte injury (ballooning), with or 
without fibrosis. NASH is associated with increased mortality rates due to cardiovascular-, liver-, 
and cancer-related deaths. Currently, there are no approved drugs for the treatment of NASH. With 
the increasing prevalence of obesity and obesity-related diseases, NASH could soon become the 
leading indication for liver transplantation and the leading cause of hepatocellular carcinoma 
(HCC) globally.
NASH patients with cirrhosis have a particularly high unmet medical need for effective therapies. 
Among NASH patients, the stage of fibrosis is the strongest predictor of disease-specific mortality, 
and patients with cirrhosis are at the greatest risk for disease-related morbidity and mortality.
Patients with cirrhosis are particularly at increased risk for poor clinical outcomes, including 
hepatic decompensation events and the need for liver transplant. It is reasonable to assume that an 
improvement in fibrosis would be predictive of clinical benefit, and a reduction of fibrosis in
patients with compensated cirrhosis, if substantial, could lead to improvements in liver function 
and long-term clinical outcomes.
Study Population: Study IM025017 will be conducted in adults who have compensated cirrhosis 
due to NASH. Participants must fully meet all eligibility criteria defined in Section 6 of the 
protocol; key inclusion and exclusion criteria are summarized as follows:

Participants meeting eligibility criteria during the screening period will enter the treatment period 
and be randomized to receive 45 mg BMS-986263 QW, 90 mg BMS-986263 QW, or placebo QW 
by IV infusion in a double-blind manner for 12 weeks. Participants will be stratified at 
Randomization by the presence of definite steatohepatitis on biopsy (yes versus no). At least 80% 
of participants will be required to have definite steatohepatitis on the biopsy used to confirm 
eligibility. Participants will receive study treatment via IV administration for a total of 12 weeks. 
Liver biopsy will be performed at Week 12.
This study will utilize an external Data Monitoring Committee for the duration of the study to 
assess safety data, and an external Independent Pathology Review Committee to assess liver 
biopsies for eligibility and efficacy.
Number of Participants: In this study, approximately 270 participants will be randomized via 
interactive response technology (IRT) in a 1:1:1 ratio to receive 45 mg BMS-986263 QW, 90 mg 
BMS-986263 QW, or placebo QW in a double-blind manner. The primary endpoint is the 
proportion of participants with ≥1 stage improvement in liver fibrosis (NASH CRN Fibrosis 
Score) as determined by liver biopsy after 12 weeks of treatment.
Assuming a Chi-Square test with an α = 0.05 and expected response rates for BMS-986263 90 mg, 
BMS-986263 45 mg, and placebo of 45%, 40%, and 20%, respectively, this study will have at 
least 80% power to detect superiority over placebo versus each dose, assuming a minimum 
difference of 20% from placebo. Accounting for a 6% dropout rate, approximately 90 participants 
will be randomized per treatment group.
Treatment Arms and Duration: Participants meeting eligibility criteria during the screening 
period will enter the treatment period. Approximately 270 participants will be randomized via IRT 
in a 1:1:1 ratio to receive 45 mg BMS-986263 QW, 90 mg BMS-986263 QW, or placebo QW by 
IV infusion in a double-blind manner for 12 weeks.
After 12 weeks of treatment or after early treatment discontinuation, participants will enter the 
24-week follow-up period. After all participants complete the Follow-up Week 4 visit, the study 
will be unblinded and analyses of the available Week 12 data will be conducted.

Statistical Methods: Efficacy analyses will be performed using the modified intent-to-treat 
population. Participants who discontinue early and do not have an Early Treatment Termination 
liver biopsy or otherwise have the result from the liver biopsy missing will be considered a 
“nonresponder” for the evaluation of the primary endpoint and other binary endpoints based on 
liver biopsy.
Primary Endpoint Analysis: To evaluate the effect of BMS-986263 (90 mg QW and 45 mg QW) 
on NASH CRN Fibrosis Stage at Week 12, a 95.0% confidence interval of response rate for active 
treatment versus placebo will be used to estimate the difference between the proportions of 
participants with ≥1 stage improvement in fibrosis on liver biopsy. Additionally, the odds ratio 
will be used to estimate improvement of treatment as compared with placebo for the proportion of 
participants with > 1 stage improvement in fibrosis on biopsy at Week 12. A logistic regression 
will be performed with platelet count as independent covariate and stratified by the Randomization 
strata with a Z-test statistic at a two-sided significance level of α◦=◦0.05 to assess the difference of 
response rate separately between each BMS-986263 treatment group and placebo. To control for 
the family-wise (two-sided) Type◦1◦error rate of α◦=◦0.05, the statistical tests will be performed 
in the following hierarchical order: 1) BMS-986263 90◦mg versus placebo, and 2) BMS-986263 
45◦mg versus placebo. If the first comparison is not statistically significant, then the second 
comparison will be treated as descriptive in nature.
Secondary 
 Endpoint Analyses: No adjustment will be made for multiplicity for 
secondary 
 endpoints. Secondary 
 endpoints will be analyzed in a 
similar method as the primary endpoint unless otherwise specified in the statistical analysis plan 
(SAP).
Selected continuous endpoints will be characterized using descriptive statistics and may be 
analyzed by analysis of covariance methods and/or by a mixed model for repeated measurements. 
Treatment differences at prespecified time points will be estimated using least squares means. Full 
details regarding this model and covariance structure will be provided in the SAP.
Categorical endpoints will be summarized using counts and percentages and when appropriate,
may be analyzed using categorical analysis methods.
The stratified log-rank test and Kaplan-Meier estimate may be used to analyze time-to-event 
endpoints and will be specified in the SAP.
Subgroup analyses may be performed as specified in the SAP.

INTRODUCTION
BMS-986263 is a lipid nanoparticle (LNP) formulation that incorporates 6 lipid components and 
a 
-conjugated targeting agent (di-retinamide-PEG-di-retinamide [DPD]). The DPD moiety 
is present on the external surface of the nanoparticle and enables targeting and uptake by hepatic 
stellate cells (HSCs, the cells responsible for hepatic collagen synthesis) via receptors for retinol 
binding protein.
The LNPs contain a small interfering ribonucleic acid (siRNA) active ingredient which is a 
nuclease-resistant, synthetic, double-stranded ribonucleic acid (RNA) designed to temporarily 
inhibit the expression of heat shock protein 47 (HSP47) via RNA interference. Briefly, RNA 
interference (RNAi) involves a process of degrading target messenger ribonucleic acid (mRNA)
transcripts, which prevents the translation of target protein. In this case, the siRNA component of 
BMS-986263, which is a nuclease-resistant, synthetic double-stranded siRNA, pairs with the 
mRNA of HSP47, thereby blocking the translation process and preventing the formation of HSP47 
protein. The resultant decreased intracellular level of HSP47 leads to a decrease in the formation 
of stable collagen, and it is hypothesized to result in decreased liver fibrosis.
3.1
Study Rationale
This study aims to demonstrate the antifibrotic efficacy of BMS-986263, using a liver fibrosis 
histological endpoint, and the safety and tolerability of BMS-986263, as assessed by adverse 
events (AEs), serious adverse events (SAEs), laboratory results (including assessment of potential 
drug-induced liver injury [DILI]), vital signs, physical examinations, electrocardiograms (ECGs), 
 infusion-related reaction (IRR) monitoring, and bone mineral density 
(BMD) monitoring, in participants with nonalcoholic steatohepatitis (NASH) and compensated 
cirrhosis.
Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver 
disease in the world today. NASH, which is the more advanced form of NAFLD, is defined as the 
presence of hepatic steatosis and inflammation with hepatocyte injury (ballooning), with or 
without fibrosis.1 NASH is associated with increased mortality rates due to cardiovascular-, liver-, 
and cancer-related deaths. Currently, there are no approved drugs for the treatment of NASH. With 
the increasing prevalence of obesity and obesity-related diseases, NASH could soon become the 
leading indication for liver transplantation and the leading cause of hepatocellular carcinoma 
(HCC) globally.2
NASH patients with cirrhosis have a particularly high unmet medical need for effective therapies. 
Among NASH patients, the stage of fibrosis is the strongest predictor of disease-specific mortality, 
and patients with cirrhosis are at the greatest risk for disease-related morbidity and mortality.3,4,5,6
Patients with cirrhosis are particularly at increased risk for poor clinical outcomes, including 
hepatic decompensation events and the need for liver transplant.
It is reasonable to assume that an improvement in fibrosis would be predictive of clinical benefit, 
and a reduction of fibrosis in patients with compensated cirrhosis, if substantial, could lead to 
improvements in liver function and long-term clinical outcomes.

Background
A detailed description of the chemistry, pharmacology, efficacy, and safety of BMS-986263 is 
provided in the Investigator’s Brochure (IB).7
Liver Fibrosis
Deposition of collagen is a tightly regulated process that is vital to normal organ structure and 
function. Cytokines associated with acute or chronic inflammation induce the production of 
collagen to provide a fibrotic band for healing. Regulation of fibrosis mechanisms ensures both 
production of sufficient quantities of specific collagen types at the appropriate time and in the 
appropriate location, and removal and remodeling to prevent accumulation of unneeded collagen 
that could impair organ and tissue function.
In some circumstances, such as when inflammatory processes and/or collagen deposition are 
prolonged, collagen removal and remodeling can become dysregulated, causing excessive amounts 
of collagen to accumulate. Hepatic fibrosis may result from a wide range of causes, including 
NASH, chronic hepatitis C virus (HCV) or hepatitis B virus (HBV) infection, and alcoholic 
hepatitis. All of these chronic diseases have a necroinflammatory component and frequently result 
in excessive collagen deposition and scarring of the liver parenchyma. This damage often leads to 
progression to cirrhosis, necrosis of hepatocytes, and end-stage liver disease.
Role of HSP47 in Liver Fibrosis
The principal cell type responsible for collagen deposition in the liver is the HSC, a resident 
perisinusoidal cell. When stimulated by reactive oxygen intermediates or inflammatory mediators 
(eg, transforming growth factor-β, tumor necrosis factor-α, and platelet-derived growth factor), 
HSCs become activated. Upon activation, HSCs are transformed into proliferative, fibrogenic, and 
contractile myofibroblasts that synthesize and secrete procollagen.8 Procollagen is enzymatically 
cleaved to form insoluble collagen that accumulates in tissue, resulting in fibrosis.
HSP47 is a necessary component of the collagen deposition mechanism in myofibroblasts. By 
acting as an intracellular chaperone of early collagen precursors for Type I to Type V collagens, 
HSP47 facilitates collagen formation, prevents collagen degradation, and ensures proper 
triple-helix formation of procollagen in the endoplasmic reticulum.9,10 While HSP47 is not the 
initiating factor in the pathologic accumulation of extracellular collagen matrix, a number of 
experimental models have shown that HSP47 is required to produce high quality collagen.11,12,13,14
Intracellular HSP47 levels increase with increased demand for collagen synthesis.10 The 
demonstration that liver fibrosis in animals15 and humans16 can regress when collagen synthesis is 
inhibited suggests that fibrosis can be reversed. This reversal most likely involves the activity of 
tissue enzymes such as matrix metalloproteinases (MMPs). Various therapeutic approaches, either 
to inhibit collagen synthesis or to activate collagen removal mechanisms, have been investigated 
in animal models.17,18 However, none have yet been applied clinically, often because of side effects 
resulting from an inability to specifically target particular molecules and/or cells.

Nonclinical Studies
Initial bioinformatic analysis predicted that BMS-986263 would be a highly selective siRNA with 
low probability of off-target activity. In vitro cellular studies performed with BMS-986263 
confirmed specificity of the RNAi activity. Additional in vitro cellular studies demonstrated potent 
RNAi activity elicited by BMS-986263 against both human and rat versions of HSP47. 
BMS-986263 elicited knockdown of HSP47 mRNA in rat primary HSCs. The presence of DPD in 
the formulation was shown to be essential for achieving RNAi activity, validating the targeting 
strategy of this formulation for effective delivery to the HSCs.
In vivo, BMS-986263 resulted in effective knockdown of HSP47 mRNA levels in rat liver after a 
single dose in the dimethylnitrosamine (DMN) quick model. Significant efficacy was also 
observed in the rat DMN chronic model of liver fibrosis as demonstrated by reduced collagen 
deposition (based on hydroxyproline level); improved histopathology, fibrosis scores with 
trichrome stain; and improved overall health based on increased total body and relative liver 
weights; compared with the Vehicle group. Refer to the BMS-986263 IB7 for further details.
The most salient toxicology findings were bone changes resulting in fractures in rats, increases in 
complement levels in monkeys, and fetal malformations in rabbits.
Gross and histological evidence of fractures were observed at doses ≥ 10 mg/kg/dose twice per 
week (BIW) in the 5-week and 8 mg/kg/dose BIW in the 13-week studies in rats.19,20 In the 
26-week rat study, there was no BMS-986263-related bone findings at any dose 
(no-observed-adverse-effect level [NOAEL] = 8 mg/kg/week, the highest dose administered, with 
steady state area under the curve (AUC) exposures of approximately 6× higher than the observed 
human exposure at a clinical dose of 
In monkeys, there were no adverse bone 
effects noted at any dose after repeated dosing for up to 39 weeks.22 The NOAEL in this study was 
15 mg/kg/week (AUC multiple: 82). Although drug product-related changes in bone size, mineral 
content, and mineral density were observed in female monkeys at all doses (2.5 mg/kg/week) 
and male monkeys at the high dose of 15 mg/kg/week, these changes were considered nonadverse
based on their small magnitude, and had no associated negative impacts on bone strength.
The underlying mechanism of the fractures in the rat is an increase in osteoclast activity in the 
subperiosteal regions of the diaphysis of long bones, a decrease in osteoclast numbers, and reduced 
osteoid in the trabecular regions of the bones, which translates into reduced bone formation. The 
literature suggests that rats are sensitive to bone fractures related to hypervitaminosis A.23,24
However, the majority of the protein in bone is collagen, and there is literature suggesting that 
HSP47 is involved in bone formation.25,26 Given the observation of fractures in animals that 
received empty-LNP formulation (ie, without siRNA inhibition of HSP47) it is hypothesized that 
LNP played a role in the observed findings.
In the 39-week repeat-dose study in monkeys, modest and transient elevations of complement 
components were reported; onset of these occurred as soon as 10 minutes postinfusion and were 
resolved by 24 hours.27 BMS-986263-related findings were limited to nonadverse changes in the

Clinical Studies
The clinical development program of BMS-986263 consists of 7 completed studies: 3 studies in 
healthy participants (ND-L02-s0201-001, ND-L02-s0201-004, and IM025001),29,30,31 3 studies in 
participants with liver fibrosis (ND-L02-s0201-002, ND-L02-s0201-003, and IM025006),32,33,34
and 1 study in participants with hepatic impairment (HI) (Study IM025015). For further details on 
the completed studies, refer to the BMS-986263 IB.7
Clinical Efficacy
The efficacy of BMS-986263 has been investigated in 3 clinical studies:

Study ND-L02-s0201-00232 (N = 25) was a Phase 1b/2, open-label, randomized, multicenter, 
repeat-dose, dose-escalation study at doses of 0.2, 0.4, and 0.6 mg/kg/week administered once 
every week (QW) or BIW for 5 weeks in participants with moderate to extensive progressive 
hepatic fibrosis (METAVIR F3 to F4) due to either NASH or chronic HCV. In this study, 
evidence indicative of biological activity was observed with improvements noted in 
METAVIR, Ishak, and Knodell fibrosis scores, as well as decreased stiffness was observed 
with Fibroscan® at Week 5, all of which are measures of hepatic fibrosis.

Study ND-L02-s0201-00333 (N = 10) was a Phase 1b/2, open-label, randomized, multicenter, 
repeat-dose, dose-escalation study at doses of 0.2, 0.4, and 0.6 mg/kg/week QW for 5 weeks 
in participants with moderate to extensive progressive hepatic fibrosis (METAVIR F3 to F4) 
due to NASH, chronic HCV, or alcoholic liver disease. In this study, evidence indicative of 
biological activity was observed with improvements noted in METAVIR, Ishak, and Knodell 
fibrosis scores, as well as decreased stiffness was observed with Fibroscan® at Week 5, all of 
which are measures of hepatic fibrosis.

Study IM02500634 was a Phase 2, randomized, double-blind, placebo-controlled study of 
45 mg BMS-986263 versus 90 mg BMS-986263 versus placebo (randomized 1:2:1) dosed 
weekly for 12 weeks in 61 participants with advanced fibrosis due to chronic HCV who had 
achieved sustained virologic response (SVR) at least 1 year prior to screening. The primary 
endpoint was the proportion of participants that achieved ≥1 stage improvement in liver 
fibrosis (METAVIR) on liver biopsy after 12 weeks of treatment. One patient who received

90 mg BMS-986263, 45 mg BMS-986263, and placebo groups, respectively.
Clinical Safety in Participants with Advanced Liver Fibrosis
In the 3 clinical studies in participants with advanced liver fibrosis, BMS-986263 was generally 
well tolerated and demonstrated an acceptable safety profile.

In studies ND-L02-s0201-002 and ND-L02-s0201-003, the most frequent AEs experienced by 
participants were temporally related to the infusion of the drug product and were mainly 
associated with IRRs. These reactions were mild to moderate in severity. The signs and 
symptoms of IRRs included, but were not limited to, back pain, fever, chills, hot or warm 
sensation, flushing, throat constriction, shortness of breath, chest tightness, tachypnea, 
tachycardia, hypotension, urticaria, pruritus, erythema, and/or edema. In general, back pain 
was the most common symptom reported for these IRRs. Refer to the BMS-986263 IB for 
more details on these studies.

In Study IM025006, IRRs were the most frequently experienced AEs. All infusion-related 
AEs were mild or moderate in intensity. The AEs associated with IRRs included back pain 
(most commonly reported), hypertension, hives/urticaria, flushing, shortness of breath, dry 
mouth, and hypoxia. In the 45 mg BMS‑986263 group, of the 6 participants who had IRRs, 
3 participants had at least 1 infusion interrupted due to an AE. In the 90 mg BMS-986263 
group, of the 15 participants who had IRRs, 13 participants had at least 1 infusion interrupted 
due to an AE. All subjects who had IRRs completed the treatment period.
In this study, BMS-986263 was not associated with evidence of

Clinical Safety and Pharmacokinetic (PK) in Participants with HI

Study IM025015 - This was a Phase 1, open-label, single-dose study to evaluate the PK, 
safety, and tolerability of BMS-986263 90 mg IV in participants with varying degrees of HI. 
Study IM025015 consisted of 2 parts. A total of 52 participants were screened, and 40 
participants were enrolled in the study: 24 of these were enrolled in Part 1 (8 participants in 
normal matched Group D, 8 participants in mild HI [Group A], and 8 participants in moderate 
HI [Group B]) and 16 participants were enrolled in Part 2 (8 participants in normal matched 
Group E and 8 participants in severe HI [Group C]). Overall, 39 participants completed the 
study, and 1 participant in the moderate HI group withdrew consent during the study. 
In this study, single doses of BMS-986263 were generally safe and well tolerated in 
participants with normal hepatic function and several degrees of HI. Most of treatment 
emergent AEs (TEAEs) were mild or moderate in severity. The most frequent two TEAEs 
were flu-like illness and IRRs. There were no TEAEs that led to death or treatment 
discontinuation. One treatment emergent SAE of hematemesis was reported in a participant 
with moderate HI and was considered not related to BMS-986263. 
Compared to the respective matching normal group, exposure estimates of BMS-986263 
siRNA exposures [geometric mean AUC(0-T) and AUC(INF)] were similar in the HI mild 
group, and 1.34- and 1.33-fold higher, respectively, in the moderate HI group and 2.63-fold 
higher for both in the severe HI group. For DPD, exposure estimates were modestly lower in 
both the mild HI and moderate HI groups, compared with the matching normal groups, whereas 
AUC(0-T), and AUC(INF) were 1.31, and 1.33 higher for the severe HI, respectively. For 
S104, higher exposure trends related to HI severity were noted in Cmax, AUC(0-T), and 
AUC(INF), with the highest exposure observed in HI severe group with a geometric mean 
AUC(0-T) 5.5-fold higher than the matching normal group. S104 is a component with a short 
half-life (~36 hours) and, based on modeling studies, it does not accumulate with weekly 
dosing. Additionally, S104 is an excipient with no known biological activity.
Based on the PK of siRNA, DPD, and S104 components of BMS-986263 and safety 
observations from this study, no dose adjustment is recommended for BMS-986263 in patients 
with mild or moderate HI. Results from this and other studies will guide the dose selection for 
patients with severe HI.
Based on the clinical studies to date, there were no safety trends observed in the laboratory 
assessments, physical examinations, vital signs, and ECG assessments. There were no changes in 
BMD as assessed by dual-energy X-ray absorptiometry (DXA) scan and there were no cases of 
potential DILI in the clinical studies.

the known and expected benefits and risks and reasonably anticipated AEs of BMS-986263 may 
be found in the IB.7
In Phase 1b and Phase 2 studies involving participants with advanced liver fibrosis, including 
compensated cirrhosis, a proportion of participants administered BMS-986263 have had an 
improvement of fibrosis. As previously mentioned, there is no approved therapy for patients with 
advanced liver fibrosis. A reduction in fibrosis in NASH patients with compensated cirrhosis may 
lead to a reduced risk liver decompensation, need for liver transplant, HCC, and mortality.
In nonclinical and Phase 1 and 2 clinical studies to date, potential risks associated with 
BMS-986263 have been identified. One is the risk of IRRs observed in the Phase 1 and 2 studies. 
In all cases, infusion reactions were mild to moderate in severity and self-limited. There was no 
evidence of anaphylaxis, and participants were not discontinued from the studies due to these 
reactions. In an attempt to reduce the risk of these IRRs, the total dose is administered in step-wise
fashion as described in the Pharmacy Manual (see Section 7.1.1). If clinical signs and/or symptoms 
indicate an IRR, the infusion may be interrupted. In addition, to potentially decrease the frequency 
or severity of infusion reactions, premedication (antihistamines and/or corticosteroids) may be 
used, at the discretion of the investigator. The premedication may be administered (at the discretion 
of the investigator) to ensure safety of the participants, as mentioned in Section 7.1.2.
Other identified risks include the impact of exposure to DPD 
 associated with 
administration of BMS-986263. These include possible impact on bone, liver, and fetal 
development.
Bone Risk
Although HSP47 and generation of collagen are important for bone formation, it is hypothesized 
that the DPD component of BMS-986263 is responsible for bone abnormalities identified in the 
nonclinical rat studies. However, no significant bone abnormalities were observed in cynomolgus 
monkeys. In this study, participants will be assessed for changes in BMD by DXA scan; 
.
Reproductive Risk
In nonclinical studies, BMS-986263 had effects on fetal development, including fetal 
teratogenicity and skeletal malformations in nonclinical rabbit studies. In this study, women of 
childbearing potential (WOCBP) and male participants who are sexually active with WOCBP must 
agree to follow instructions for method(s) of highly effective contraception, as defined in 
APPENDIX 4.
Other DPD-Risks, Including Liver Risk
The theoretical risk of DPD-related liver toxicity is mitigated by the short treatment duration of 
this study (12 weeks). In the previous Phase 2 study in HCV-SVR participants, no participants had 
a constellation of clinical signs and symptoms that was suggestive of 
. 
Furthermore, there was no laboratory evidence of potential DILI or new histologic changes 
suggestive of 
 to HSCs. In this study, all participants will be monitored closely for 
signs and/or symptoms of

serial history, abdominal physical exams, and laboratory assessments. 
 
 
In this study, participants will be queried for symptoms suggestive of 
 including 
but not limited to dry skin, vaginal dryness, cheilosis, gingivitis, muscle and joint pains, fatigue, 
mental dullness, and depression. Physical examinations during 
 evaluation will be 
performed that include signs of 
 including skin and oral mucosa changes and 
hepatomegaly.
Additional safety monitoring will include laboratory assessments to rule out development of 
anemia, leucopenia, thrombocytopenia, liver enzyme (aspartate aminotransferase [AST], alanine 
aminotransferase [ALT], alkaline phosphatase [ALP]) and total bilirubin elevations. Use of 
over-the-counter (OTC) herbal supplements and multivitamins containing vitamin A (including 
Cod liver oil), or other medications that may contain vitamin A, are prohibited while participating 
in the study (Section 7.7.1). Prior to starting study treatment and throughout the study, participants 
will be educated about vitamin A-containing foods, medications, and herbal supplements, as well 
as the signs and symptoms of vitamin A toxicity. In addition, liver biopsy specimens will also be 
assessed for histologic evidence suggestive of 
 (Section 9.4.6).
In order to minimize the overall risk to participants, this protocol has eligibility criteria appropriate 
to the population and proposed treatments, exclusionary screening tests, and specific follow-up 
safety assessments. In addition, the AEs and SAEs will be reviewed on an ongoing basis by the 
Medical Monitors and the pharmacovigilance group to look for trends and any emergent or 
unexpected safety issues. An independent Data Monitoring Committee (DMC) will also review 
safety data on a regular basis.
3.3.2
Coronavirus Disease 2019-Related
The ongoing global coronavirus disease 2019 (COVID-19) pandemic has been identified as a 
potential risk to trial participants in general and it may particularly affect individuals with 
underlying chronic diseases. The individual benefit-risk considerations regarding COVID-19 
infection remains the responsibility of the investigator. Vaccination as well as testing to exclude
infection prior to enrollment and to inform decisions about participant care during the study
should follow local standard practice and requirements. Non-live COVID-19 vaccination is 
allowed during the study, will be documented as a concomitant medication, and should follow 
local standard practices during administration. The efficacy and safety of COVID-19 vaccines in 
subjects receiving BMS-986263 are unknown. BMS-986263 is not immunomodulatory. It is not 
known whether taking BMS-986263 changes the risk of SARS-CoV-2 infection, or the duration 
or severity of COVID-19 disease.

The investigator will maintain a screening log to record details of all participants screened and to 
confirm eligibility or record reasons for screening failure, as applicable. Certain procedures 
conducted as part of the participant’s routine clinical management and obtained before signing of 
informed consent may be utilized for screening purposes provided the procedure meets the 
protocol-defined criteria and has been performed within the timeframe defined in the Schedule of 
Activities (SOA) (Section 2).
Randomization should occur within 56 days (8 weeks) of signing the informed consent. The 
screening period may be extended (up to an additional 4 weeks) to accommodate unanticipated 
delays in obtaining required screening results.
Visit details are provided in the Screening Procedural Outline in the SOA (Section 2).
5.1.2
Treatment Period and Follow-up
Participants meeting eligibility criteria during the screening period will enter the treatment period. 
Approximately 270 participants will be randomized via interactive response technology (IRT) in 
a 1:1:1 ratio to receive 45 mg BMS-986263 QW, 90 mg BMS-986263 QW, or placebo QW by IV 
infusion in a double-blind manner.
Participants will be stratified at Randomization by the presence of definite steatohepatitis on 
biopsy (yes versus no). At least 80% of participants will be required to have definite steatohepatitis
on the biopsy used to confirm eligibility. Participants will receive study treatment via IV infusion 
for a total of 12 weeks. Liver biopsy will be performed at Week 12.
After 12 weeks (Day 85) of treatment or after early treatment discontinuation, participants will 
enter the 24-week follow-up period, during which participants will not receive investigational 
treatment. After all participants complete the Follow-up Week 4 visit, the study will be unblinded 
and analyses of the available Week 12 data will be conducted (Section 10.4.4). Participants who 
discontinue study treatment before the Week 11 Visit will have an Early Treatment Termination 
(ETT) visit and will continue into the 24-week follow-up period.
See the SOA in Table 2 and Table 3 (Section 2).
5.1.3
DMC and Other External Committees
This study will utilize an external DMC for the duration of the study. Data summaries and listings 
will be provided to the DMC to facilitate their assessments at the regularly scheduled times and on 
an ad hoc basis if needed. The safety review includes SAEs and events of special interest (eg, bone 
fractures, IRRs, and anaphylaxis), focusing on early signal detection. This study will also utilize 
an Independent Pathology Review Committee (IPRC) to perform central pathology assessments 
of the liver biopsy samples to support study eligibility and histological efficacy endpoints analyses.

Scientific Rationale for Study Design
Phase 1b and Phase 2 studies of BMS-986263 enrolled participants with advanced liver fibrosis 
caused by NASH or HCV. Review of safety data from these studies demonstrated that 
BMS-986263 was generally safe and well tolerated. Based on efficacy data from the small number 
of participants in these studies who had advanced liver fibrosis, Study IM025017 will investigate 
the effects of BMS-986263 in a larger population of participants with compensated cirrhosis due 
to NASH.
The focus of this placebo-controlled, Phase 2 study is to demonstrate the efficacy, safety, 
tolerability, PK, 
 effects of BMS-986263 in participants with 
compensated cirrhosis due to NASH. The study schematic is provided in Figure 1.
The study will seek to confirm the findings of prior clinical studies demonstrating improvement in 
fibrosis in participants with advanced liver fibrosis. In this study, BMS-986263 at doses of 45 mg 
or 90 mg QW for 12 weeks, compared with placebo, will be utilized to assess proof-of-concept of 
the efficacy (as measured by the improvement of liver fibrosis), safety, and tolerability of 
BMS-986263 in the study population. The 45 mg and 90 mg doses were chosen because these 
doses were studied in the prior Phase 2 study of HCV-SVR patients; these doses appeared to be 
efficacious and were generally safe and well tolerated. A treatment duration of 12 weeks was 
chosen because an antifibrotic effect was observed after 12 weeks of therapy in that study. The 
follow-up period will allow assessment (utilizing noninvasive assessments of fibrosis) of the 
off-treatment durability of efficacy through Follow-up Week 24 (or up to 36 weeks total duration).
Efficacy, safety, PK, 
 effects will be compared with results from placebo-treated 
participants and across treatment arms to identify the optimal doses and dosing regimen for future 
development.
Complete details of the study design are provided in Section 5.

Screen Failures
Screen failures are defined as participants who consent to participate in the clinical study 
(ie, enroll) but are not subsequently randomized into the study. A minimal set of screen failure 
information is required to ensure transparent reporting of screen failure participants, to meet the 
Consolidated Standards of Reporting Trials publishing requirements, and to respond to queries 
from regulatory authorities. Minimal information includes date of consent, demography, screen 
failure details, eligibility criteria, and any serious AEs. 
 
6.6.1
Retesting During Screening Period
Participant Re-enrollment: This study permits the re-enrollment of a participant that has 
discontinued the study as a pretreatment failure (ie, participant has not been randomized/has not 
been treated). If re-enrolled, the participant must be re-consented.
Retesting of laboratory parameters and/or other assessments within any single screening or lead-in 
period will be permitted (in addition to any parameters that require a confirmatory value). The 
most current result prior to Randomization is the value by which study inclusion will be assessed, 
as it represents the participant’s most current, clinical state. Laboratory parameters and/or 
assessments that are included in Table 1, Screening Procedural Outline may be repeated in an 
effort to find all possible well-qualified participants. Consultation with the Medical Monitor may 
be needed to identify whether repeat testing of any particular parameter is clinically relevant.
Participants who are screen failures may be rescreened only once; additional rescreening may be 
allowed after consultation with the Medical Monitor. An additional rescreening is permitted for 
study participants who have failed screening due to SARS-CoV-2 infection. All participants who 
are re-enrolled will be assigned a new participant identification. For participants who are 
rescreened, 
 DXA scan assessments can be reused without repeating if 
performed 3 months prior to rescreening visit (Section 2).

TREATMENT
Study treatment is defined as any investigational treatment(s), marketed product(s), placebo, or 
medical device intended to be administered to a study participant according to the study 
randomization or treatment allocation.
Study 
treatment 
includes 
both 
investigational 
[medicinal] 
product 
(IP/IMP) 
and 
non-investigational [medicinal] product (nonIP/nonIMP) as shown in Table 5.
An IP, also known as IMP in some regions, is defined a pharmaceutical form of an active substance 
or placebo being tested or used as a reference in a clinical study, including products already with 
a marketing authorization but used or assembled (formulated or packaged) differently than the 
authorized form, or used for an unauthorized indication, or when used to gain further information 
about the authorized form.
Other medications used as support or escape medication for preventative, diagnostic, or therapeutic 
reasons, as components of the standard of care for a given diagnosis, may be considered as nonIP.

Please refer to the Pharmacy Manual for complete information on BMS-986263 and placebo 
storage, handling, and exact volumes, and instructions on the preparation of study treatment 
infusion.
Treatment Administration
The study treatment will be infused using an IV pump, as described in the Pharmacy Manual. The 
IV access will be kept open before and after the infusion with sufficient quantities of 0.9%◦saline 
or 5% dextrose in water to assure it remains patent. The time the infusion is 
initiated/adjusted/concluded, including any interruptions, will be documented in the electronic 
case report form (eCRF).
Study treatment infusions should be administered on the same day of each week to the extent that 
this is possible with a window of ± 3 days. Infusions must be separated by at least 3 days. At the 
study treatment infusion visits, all study procedures and assessments must be completed prior to 
initiation of the study treatment infusion (with the exception of PK samples collected during and 
postinfusion). When fasting is required for the preinfusion study procedures, participants may eat 
once all of the preinfusion testing and assessments are performed.

7.1.1
Study Treatment Infusion Rate
The study medication is suggested to be infused in a step-wise approach as described below, as 
used in the IM025006 final clinical study report (CSR)34. The total dose of the study medication 
should not be infused in less than 60 minutes. The initial rate of the administration should not be 
any greater than the initial rate specified below.
Recommended blinded treatment stepped titration infusion rates:
The infusion rates may be decreased by the investigator based on the participant’s previous 
tolerance of the infusion, including any IRRs that may have occurred in the past. Consultation with 
the Medical Monitor is recommended if any other modification of these recommended infusion 
rates is being considered. In addition, the investigator may choose to pause the infusion depending 
on the participant’s clinical condition and history. If clinical signs and/or symptoms indicate an 
IRR, the infusion may be interrupted. If the infusion is interrupted for any reason, the infusion may 
be restarted at the discretion of the investigator.
Additional details on IRRs, including the management of IRRs, are provided in Section 9.2.9.
7.1.2
Premedication
Based on the discretion of the investigator, the participants may be administered IV or oral 
premedication approximately 
, respectively, before the start of the study 
treatment infusion. The investigator may choose to administer IV antihistamines 
(eg, diphenhydramine 
hydrochloride 50 mg, 
famotidine 20 mg) or oral antihistamines 
(eg, levocetirizine 
5 mg) 
and/or 
IV corticosteroids 
(eg, hydrocortisone 100 mg 
or 
methylprednisolone sodium succinate 125 mg).
Participants who receive antihistamine premedication should be advised that the premedication 
may be sedating and cautioned against driving or operating heavy machinery for at least 3 hours 
after administration. For sites participating in the 
, the pretreatment 
 
activities must be completed prior to the start of any premedication.
7.2
Method of Treatment Assignment
At the time of the screening visit, before any study-related procedures are performed, the 
investigative site will access the enrollment option of the IRT system for assignment of a subject
number. This number is assigned sequentially by the system and will be unique across all sites. If 
a potential participant is rescreened, a new identification number will be used.
Before the study is initiated, each user (at investigative sites) will receive log-in information and 
directions on how to access the IRT. Study treatment will be dispensed and administered at the 
study visits as listed in SOA (Section 2).

stratification criteria. Randomization to a treatment group will be assigned prior to dosing.
7.3
Blinding
7.3.1
Maintaining the Blind
Blinded treatment assignments will be managed using IRT. All infusion solutions (prepared by an 
unblinded pharmacist (or another appropriately delegated qualified individual) at the investigative 
site per the Pharmacy Manual) are matching in appearance, and will be supplied as shown in Table 
6. Investigative site staff, Sponsor and designee personnel, and participants and their families will 
remain blinded to treatment assignments.
The investigative site staff will include the following:

An unblinded pharmacist (or another appropriately delegated qualified individual), who will 
be responsible for preparing the infusion solutions and providing in a blinded manner to the 
study team, ensuring that the infusion solutions are protected from light as described in the 
Pharmacy Manual. The unblinded pharmacist (or another appropriately delegated qualified 
individual) must not reveal potentially unblinding information to the study team.
7.3.2
Circumstances for Unblinding
Blinding of treatment assignment is critical to the integrity of this clinical study. However, in the 
event of a medical emergency or pregnancy in an individual participant in which knowledge of the 
IP is critical to the participant’s management, the blind for that participant may be broken by the 
investigator. The participant’s safety takes priority over any other considerations in determining if 
a treatment assignment should be unblinded.
Before breaking the blind of an individual participant’s treatment, the investigator should 
determine that the unblinded information is necessary (ie, that it will alter the participant’s 
immediate medical management). In many cases, particularly when the emergency is clearly not 
related to the IP, the problem may be properly managed by assuming that the participant is 
receiving active product. It is highly desirable that the decision to unblind treatment assignment 
be discussed with the Medical Monitor, but the investigator always has ultimate authority for the 
decision to unblind. The actual TASK of unblinding can be delegated by the investigator to a 
designee assigned the task on the Delegation of Authority. The principal investigator or appointed 
designee should only call in for emergency unblinding AFTER the decision to unblind the 
participant has been documented.
In case of an emergency, the investigator has unrestricted access to randomization information via 
IRT and is capable of breaking the blind through the IRT system without prior approval from the 
Sponsor. After the unblinding, the investigator shall notify the Medical Monitor and/or Study 
Director. The method of unblinding for emergency purposes is described in the reference 
manual(s).

In cases of accidental unblinding, contact the Medical Monitor and ensure every attempt is made 
to preserve the blind. Any request to unblind a participant for nonemergency purposes should be 
discussed with the Medical Monitor.
Designated staff of BMS Research & Development may be unblinded (obtain the randomization 
codes) prior to database lock to facilitate the bioanalytical analysis of PK samples 
 
. A bioanalytical scientist in the Bioanalytical Sciences department of BMS 
Research & Development (or a designee in the external central bioanalytical laboratory) will be 
unblinded to (may obtain) the randomized treatment assignments in order to minimize unnecessary 
bioanalytical analysis of samples.
The study will be unblinded once all participants have completed the Follow-up Week 4 visit and 
all data have been collected through that time point to facilitate analyses (Section 10.4.4).
7.4
Dosage Modification
No reductions or modifications of the assigned dose are allowed. If the infusion is interrupted for 
any reason, the infusion may be restarted at the discretion of the investigator. If an incomplete dose 
is administered at any visit, the participant will resume the assigned dose/administration schedule 
at the next visit. See Section 9.2.9 for management of IRRs.
7.5
Preparation/Handling/Storage/Accountability
The IP should be stored in a secure area according to local regulations. It is the responsibility of 
the investigator to ensure that IP is only dispensed to study participants. The IP must be dispensed 
only from official study sites by authorized personnel according to local regulations.
 
 
 
 
 
 
The product storage manager should ensure that the study treatment is stored in accordance with 
the environmental conditions (temperature, light, and humidity) as determined by BMS. If 
concerns regarding the quality or appearance of the study treatment arise, the study treatment 
should not be dispensed and BMS contacted immediately.
Please refer to the Pharmacy Manual for IP preparation.
Study treatment not supplied by BMS will be stored in accordance with the package insert.
The IP documentation (whether supplied by BMS or not) must be maintained that includes all 
processes required to ensure drug is accurately administered. This includes documentation of drug 
storage, administration, and, as applicable, storage temperatures, reconstitution, and use of 
required processes (eg, required diluents, administration sets).

screening visit. Concomitant medications are defined as any medication taken after the first dose 
of study medication until the last study visit. Concomitant medications (prescription, OTC, or 
herbal) should be administered during the study only if they are prescribed for treatment of specific 
clinical events.
Participants taking vitamin E, SGLT2 inhibitors, GLP-1 receptor agonists, anti-obesity agents, or 
an approved NASH treatment at stable doses prior to screening (as specified in Section 6.1) should
maintain stable dosing throughout the entire study. In certain circumstances, dose modifications 
of concomitant medications may be made based upon the investigator’s clinical judgement, after 
consultation with the Medical Monitor.
SARS-CoV-2 vaccines approved for Emergency Use Authorization by local regulatory agency
that are not live attenuated are allowed during the study and should be handled in the same manner 
as other vaccines.
7.7.1
Prohibited and/or Restricted Treatments
Restrictions and prohibitions on prior and concomitant medications and/or treatments are as 
follows:
1) Prior exposure to BMS-986263 is prohibited.
2) NASH therapies with only accelerated approval from the US FDA or conditional approval 
from the European Medicines Agency are prohibited from the time of the liver biopsy to 
confirm eligibility until Week 12 or early termination.
3) OTC herbal supplements or multivitamins containing vitamin A (including Cod liver oil), or 
other medications that may contain vitamin A are prohibited after signing the ICF and 
throughout the study.
4) Other investigational agents. Any other investigational agent must be discontinued at least 
3 months prior to the liver biopsy used to confirm eligibility or within 12 weeks or 5 half-lives 
prior to the first dose of study treatment, whichever is longer.
5) Medical or surgical treatments for obesity should not be initiated while the participant is 
participating in the study.

and to evaluate efficacy. A historical biopsy may be acceptable to determine eligibility, if (1) the 
liver biopsy was performed within 12 months prior to screening, as defined in Section 6.1, and 
(2) adequate sample is available for assessment by central pathology. If a historical biopsy is 
unavailable, a liver biopsy will be performed during screening and will be assessed by central 
pathology reading to determine eligibility. A percutaneous liver biopsy is preferred to a 
transjugular biopsy. The investigator must consult with the Medical Monitor prior to performing 
a transjugular biopsy. Participants must have a liver biopsy demonstrating NASH CRN Fibrosis 
Score Stage 4 liver fibrosis (as determined by central pathology) and meeting all other liver 
biopsy-related inclusion and exclusion criteria as defined in Section 6.1 and Section 6.2, 
respectively, to be eligible. Liver biopsy assessments at screening may be shared with the sites. 
Any local incidental findings of potential clinical relevance identified at screening that are not 
directly associated with the objectives of the protocol should be evaluated and handled by the study 
investigator as per standard medical/clinical judgment. Participants who have a prolonged INR 
and/or lower platelet count may receive treatments to correct coagulation abnormalities and/or low 
platelet counts prior to liver biopsy based on investigator’s clinical judgment in order to reduce 
the risk of bleeding. It is the investigator’s responsibility to assess any potential risks that may be 
associated with the use of these agents (eg, transfusion of fresh/frozen plasma or platelets).37
Additional details on liver biopsy sample collection, preparation, and submission, as well as central 
pathology procedures are described in the Laboratory Manual.
Tissue from biopsies performed during the study will be collected for analysis. Histological 
assessments related to efficacy of BMS-986263 will be performed by central pathology reading. 
The on-treatment liver biopsy results will remain blinded to site personnel until at least 
post-database lock. If local pathology assessment is necessary, a portion of the sample should be 
submitted to a local pathologist following the standard procedure utilized by the study site. Any 
local incidental findings of potential clinical relevance identified at this post-baseline assessment 
that are not directly associated with the objectives of the protocol should be evaluated and handled 
by the study investigator as per standard medical/clinical judgment.
Liver tissue should be collected using a 16-gauge (or larger lumen) cutting needle (eg, Bard,
Microvasive, or TruCut) whenever possible. Use of suction needles (eg, Menghini, Jamshedi, or 
Klatskin) should be avoided because they may cause fragmentation of fibrotic specimens and 
impede the evaluation of fibrosis.38 Use of suction needles should be discussed with the Medical 
Monitor. At least 2 cm length of tissue should be obtained. Additional details on the acquisition, 
quality requirements, histological preparation, and shipping of histological samples are in the 
Laboratory Manual.
9.1.2.1
Histological Scoring
For associated endpoints, the NASH CRN system39 will be used to score the histologic samples by 
the central pathologist and results are reported as the NASH CRN Fibrosis Score and the NAS. The 
NASH CRN system is based on the concept that stage of fibrosis and necroinflammatory lesions 
should be evaluated separately; it assesses liver biopsies for degree of fibrosis (0 to 4), steatosis 
(0 to 3), lobular inflammation (0 to 3), and hepatocellular ballooning (0 to 2).

NASH CRN Fibrosis
For the NASH CRN Fibrosis Score, fibrosis is staged on a 0 to 4 scale: 0 (none); 1 (perisinusoidal 
or periportal fibrosis); 2 (perisinusoidal and portal/periportal fibrosis); 3 (bridging fibrosis); 
4 (cirrhosis).
NAS
Steatosis, lobular inflammation, and ballooning scores are added together in an unweighted fashion 
to determine the NAS, which ranges from 0 to 8 (Table 7).
The NAS should not be considered a replacement for the diagnosis of NASH.

A modified Ishak scoring system40 will be used as a secondary endpoint to grade fibrosis in the
histologic samples. The Ishak system (0 to 6 scale) was originally developed to grade portal-based
liver fibrosis associated with viral hepatitis. The modified Ishak system has been adapted to grade 
central-based liver fibrosis associated with NASH, and it also uses a 0 to 6 scale:

0: No fibrosis

1: perisinusoidal or periportal fibrosis

2: perisinusoidal and portal/periportal fibrosis

 in Stained Tissue
Assessment of CPA is a method by which the amount (percentage) of collagen in stained tissue 
sections is analyzed using morphometric image analysis. This allows for a quantitative assessment 
of fibrosis.

Adverse Events
The definitions of an AE or SAE can be found in APPENDIX 3.
AEs will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or the 
participant’s legally authorized representative).
The investigator and any designees are responsible for detecting, documenting, and reporting 
events that meet the definition of an AE or SAE and remain responsible for following up AEs that 
are serious, considered related to the study treatment or the study, or that caused the participant to 
discontinue before completing the study.
Contacts for SAE reporting specified in APPENDIX 3.
9.2.1
Time Period and Frequency for Collecting AE and SAE Information
The collection of nonserious AE information should begin at initiation of study treatment until 
discharge, at the time points specified in the SOA (Section 2). Nonserious AE information should 
also be collected from the start of a placebo lead-in period or other observational period intended 
to establish a baseline status for the participants. The Reference Safety Information in 
Sections 5.6.1 and 5.6.2 of the IB7 should be used to determine the expectedness of SAEs for 
expedited reporting.
All SAEs must be collected from the time of signing the consent, including those thought to be 
associated with protocol-specified procedures and within 30 days of discontinuation of dosing (or 
participant’s participation in the study if the last scheduled visit occurs at a later time).

The investigator must report any SAE that occurs after this time period and that is believed to 
be related to study treatment or protocol-specified procedure (eg, a follow-up skin biopsy).

Medical occurrences that begin before the start of study treatment but after obtaining informed 
consent will be recorded on the appropriate section of the eCRF.

All SAEs will be recorded and reported to the Sponsor or designee within 24 hours, as 
indicated in APPENDIX 3.

The investigator will submit any updated SAE data to the Sponsor or designee within 24 hours 
of updated information being available.
Investigators are not obligated to actively seek AEs or SAEs from former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a participant 
has been discharged from the study, and he/she considers the event reasonably related to the study 
treatment or study participation, the investigator must promptly notify the Sponsor or designee.
The method of evaluating intensity and assessing causality of AEs and SAEs and the procedures 
for completing and reporting/transmitting SAE reports are provided in APPENDIX 3.

9.2.2
Method of Detecting AEs and SAEs
AEs can be spontaneously reported or elicited during open-ended questioning, examination, or 
evaluation of a participant. (In order to prevent reporting bias, participants should not be 
questioned regarding the specific occurrence of one or more AEs.)
Participants will be queried for symptoms suggestive of vitamin A toxicity including but not 
limited to dry skin, vaginal dryness, cheilosis, gingivitis, muscle and joint pains, fatigue, mental 
dullness, and depression.
9.2.3
Follow-up of AEs and SAEs

Nonserious AEs should be followed to resolution, or stabilization, or reported as SAEs if they 
become serious (APPENDIX 3).

Follow-up is also required for nonserious AEs that cause interruption or discontinuation of 
study treatment and for those present at the EOS treatment as appropriate.

All identified nonserious AEs must be recorded and described on the nonserious AE page of 
the eCRF. Completion of supplemental eCRFs may be requested for AEs and/or laboratory 
abnormalities that are reported/identified during the course of the study.
After the initial AE/SAE report, the investigator is required to proactively follow each participant 
at subsequent visits/contacts. All SAEs and nonserious AEs of special interest (AESI) (defined in 
Section 9.2.8) will be followed until resolution, until the condition stabilizes, until the event is 
otherwise explained, or until the participant is lost to follow-up (as defined in Section 8.3).
Further information on follow-up procedures is given in APPENDIX 3.
9.2.4
Regulatory Reporting Requirements for SAEs

Prompt notification by the investigator to the Sponsor of SAEs is essential so that legal 
obligations and ethical responsibilities toward the safety of participants and the safety of a 
product under clinical investigation are met.

An investigator who receives an investigator safety report describing SAEs or other specific 
safety information (eg, summary or listing of SAEs) from the Sponsor will file it along with 
the IB and will notify the IRB/IEC, if appropriate according to local requirements.
Sponsor or designee will report AEs to regulatory authorities and IECs according to local 
applicable laws including European Directive 2001/20/EC and the following FDA CFRs:
21 CFR Part 312 and Part 320. A Suspected Unexpected Serious Adverse Reaction is a subset of 
SAEs and will be reported to the appropriate regulatory authorities and investigators following 
local and global guidelines and requirements.
9.2.5
Pregnancy
If, following initiation of the study treatment, it is subsequently discovered that a participant is 
pregnant or may have been pregnant at the time of study exposure, including during at least 
5 half-lives (20 days) after study product administration, the study treatment must be discontinued

immediately and the investigator must immediately notify the Sponsor or designee of this event 
and complete and forward a Pregnancy Surveillance Form to the Sponsor or designee within 
24 hours of awareness of the event and in accordance with SAE reporting procedures described in 
APPENDIX 3.
The investigator must also notify the Medical Monitor or designee of this event within 24 hours 
of awareness of the pregnancy.
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
participant.
Follow-up information regarding the course of the pregnancy, including perinatal and neonatal 
outcome and, where applicable, offspring information must be reported on the Pregnancy 
Surveillance Form.
Any pregnancy that occurs in a female partner of a male study participant should be reported to 
the Sponsor or designee. In order for Sponsor or designee to collect any pregnancy surveillance 
information from the female partner, the female partner(s) must sign an ICF for disclosure of this 
information. Information on this pregnancy will be collected on the Pregnancy Surveillance Form.
9.2.6
Laboratory Test Result Abnormalities
The following laboratory test result abnormalities should be captured on the AE eCRF page:

Any laboratory test result that is clinically significant or meets the definition of an AE or SAE

Any laboratory test result abnormality that required the participant to have study treatment 
discontinued or interrupted

Any laboratory test result abnormality that required the participant to receive specific 
corrective therapy
If a laboratory test result meets the definition of an AE or SAE, the laboratory test result should be 
reported as an AE or SAE and submitted to the Sponsor or designee, as specified in APPENDIX 3.
It is expected that wherever possible, the clinical rather than laboratory term would be used by the 
reporting investigator (eg, anemia versus low hemoglobin value).
9.2.7
Potential DILI
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential DILI event. The definition of potential DILI, as well as 
study treatment discontinuation criteria, are provided in Section 8. All occurrences of potential 
DILIs, meeting the defined criteria, must be reported as SAEs (see APPENDIX 3 for reporting 
details). Participants who meet criteria for potential DILI should have relevant laboratory testing 
(eg, ALT, AST, total bilirubin, and INR) repeated at least weekly until abnormalities have resolved 
or returned to baseline. Tests should be repeated within 3 days; then within every 3 days thereafter 
until reversal is noted; and thereafter, every week until normalization (or return to baseline). The 
investigator should make every effort to determine if any other cause for the liver test abnormalities 
is present.

Adverse Events of Special Interest
All AEs and SAEs that arise in the study will be reported and investigated. However, because of 
the characteristics of the disease under study and BMS-986263 in particular, some AEs are 
considered AESI. AESI may be serious or nonserious. Such events may require further 
investigation to better characterize and understand them. In the BMS-986263 clinical development 
program, bone fractures, IRRs, and anaphylaxis have been identified as potential AESI; however, 
there has been no definitive assessment of the causal relationship between these events and 
treatment with BMS-986263.
9.2.9
Infusion-related Reactions
An IRR is defined as: Any AE that occurs after the start and within 24 hours after the start of 
infusion of the IP and meets at least 1 of the following criteria:

Considered to be at least possibly related to the IP.

Resulted in interruption of infusion.

Resulted in change of the infusion rate.

Was considered by the investigator to be an IRR.
Note: Local reactions related to the infusion site are not considered IRRs.
In previous clinical studies of BMS-986263, in participants who experienced IRRs, back pain was 
the most common symptom reported for these IRRs. Other signs and symptoms less commonly 
associated with IRRs included, but were not limited to the following: hot or warm sensation, 
flushing, throat constriction, shortness of breath, chest tightness, tachypnea, tachycardia, 
hypertension, urticaria, pruritus, and/or erythema. These reactions routinely had a rapid onset 
within 
 after start of the infusion and were generally short lasting with most 
resolving within 
 of their occurrence.
The details of IP administration and infusion rate for this study are provided in Section 7.1.
If a participant experiences an IRR, temporary interruption of the infusion and/or reduction of the 
infusion rate may lead to improvement of signs and symptoms. The infusion may be restarted, at 
the discretion of the investigator, after signs and symptoms of IRRs have abated.
Medications, emergency equipment, and trained personnel able to treat immediate or delayed IRRs 
should be available for immediate access at the clinical site(s).
9.2.10
Other Safety Considerations
Any significant worsening noted during interim or final physical examinations, ECG, x-ray 
filming, or any other potential safety assessment required or not required by protocol should also 
be recorded as a nonserious or serious AE, as appropriate, and reported accordingly.

Overdose
For this study, any dose of BMS-986263 for injection > 10% above the assigned dose (eg, 
of study drug infusion) within a 24-hour time period will be considered an overdose. 
See APPENDIX 3 for AE/SAE reporting requirements for overdose.
In the event of an overdose, the investigator should do the following:
1) Contact the Medical Monitor immediately.
2) Closely monitor the participant for AEs/SAEs and laboratory abnormalities until BMS-986263 
can no longer be detected systemically (at least 20 days).
3) Obtain a plasma sample for PK analysis within 2 days from the date of the last dose of study 
treatment if requested by the Medical Monitor (on a case-by-case basis).
4) Document the quantity of the excess dose as well as the duration of the overdosing in the eCRF.
9.4
Safety
Planned time points for all safety assessments are listed in the SOA (Section 2). All urgent safety 
concerns must be discussed with the Sponsor immediately upon occurrence or awareness to 
determine if the participant should continue or discontinue treatment.
The safety and tolerability of BMS-986263 will be assessed by evaluation of the incidence of all 
AEs (including AESI) and SAEs, laboratory results (including assessment of potential DILI), vital 
signs, physical examinations, ECG monitoring, 
 IRR monitoring, and 
change in BMD.
The participants must not have documented bone abnormalities at baseline as defined in the 
exclusion criteria (Section 6.2). DXA scan will be used to assess BMD.
9.4.1
Clinical Safety Laboratory Assessments
Investigators must document their review of each laboratory safety report. A central laboratory 
will perform the analyses and will provide reference ranges for these tests, except as noted below.

or someone who is authorized to perform the examinations by training and has been delegated this 
task by the principal investigator.
A physical exam for signs of 
, including skin and oral mucosa changes and 
hepatomegaly, will be performed at visits listed in the SOA (Section 2).
A full examination will include general appearance, skin, head, eyes, ears, nose, throat, neck, 
thyroid, chest/lungs, heart, abdomen, lymph nodes, and extremities. If the screening full physical 
examination is performed within 24 hours prior to dosing on Day 1, then a single exam may count 
as both the screening and Day 1 (abbreviated) physical examination.
Abbreviated physical exams will include an abdominal exam, assessments of ascites and hepatic 
encephalopathy, and symptom-focused assessments. An abbreviated examination may note any 
changes in the participant’s condition (body systems) since the last assessment and does not 
preclude examination of any of the other body systems as clinically indicated. Every effort should 
be made to ensure the same evaluator will complete the examination for each participant at all

Imaging Safety Assessment – DXA Scan
DXA scan (hip [including femoral neck] and lumbar spine) will be performed at the time points 
indicated in the SOA (Section 2).
Image acquisition guidelines and submission processes will be outlined in the site imaging manual, 
to be provided by the central imaging vendor. The sites will be trained and qualified in imaging 
procedures prior to scanning the first study participant. All images will be submitted to the central 
imaging vendor for assessment of the BMD.
Adequacy of DXA scan must be determined by the central imaging vendor prior to Randomization. 
The site will be informed of quality issues or the need to repeat scanning from the central imaging 
vendor. Note that at least 1 of the requested anatomic sites (hip [including femoral neck] or lumbar 
spine) must be evaluable for participants to be eligible for the study (See Section 6.2).
Any local incidental imaging findings of potential clinical relevance that are not directly associated 
with the objectives of the protocol should be evaluated and handled by the study investigator as 
per standard medical/clinical judgment.

STATISTICAL CONSIDERATIONS
10.1
Sample Size Determination
In this study, approximately 270 participants will be randomized via IRT in a 1:1:1 ratio to receive 
45 mg BMS-986263 QW, 90 mg BMS-986263 QW, or placebo QW by IV infusion in a 
double-blind manner. The primary endpoint is the proportion of participants with ≥1 stage 
improvement in liver fibrosis (NASH CRN Fibrosis Score) as determined by liver biopsy after 
12 weeks of treatment.
Assuming a Chi-Square test with an α = 0.05 and expected response rates for BMS-986263 90 mg,
BMS-986263 45 mg, and placebo of 45%, 40%, and 20%, respectively, approximately 
85 evaluable participants per treatment group in this study will have at least 80% power to detect 
superiority over placebo versus each dose, assuming a minimum difference of 20% from placebo. 
Accounting for a 6% dropout rate, approximately 90 participants will be randomized per treatment 
group.
10.2

Statistical Analyses
The statistical analysis plan (SAP) will be finalized prior to the first unblinding event of the study 
and will provide detailed specifications of the analysis of all efficacy endpoints and safety and will 
also describe the populations used for analyses and procedures for accounting for missing, unused, 
and spurious data.
This section provides a summary of planned statistical analyses.
10.4.1
Efficacy Analyses
Efficacy analyses will be performed using the mITT population. Participants who discontinue early 
and do not have an ETT liver biopsy or otherwise have the result from the liver biopsy missing 
will be considered a “nonresponder” for the evaluation of the primary endpoint and other binary 
endpoints based on liver biopsy.
Primary Endpoint: To evaluate the effect of BMS-986263 (90 mg QW and 45 mg QW) on NASH 
CRN Fibrosis Stage at Week 12, a 95.0% confidence interval (CI) of response rate for treatment 
versus placebo will be used to estimate the difference between the proportions of participants with 
≥1 stage improvement in fibrosis on liver biopsy. Additionally, the odds ratio will be used to 
estimate improvement of treatment as compared with placebo for the proportion of participants 
with > 1 stage improvement in fibrosis on biopsy at Week 12. A logistic regression will be 
performed with platelet count as continuous independent covariate and stratified by the 
Randomization strata with a Z-test statistic at a two-sided significance level of α◦=◦0.05 to assess 
the difference in distribution of response rate separately between each BMS-986263 treatment 
group and placebo. To control for the family-wise (two-sided) Type◦1◦error rate of α◦=◦0.05, the 
statistical tests will be performed in the following hierarchical order: 1) BMS-986263 90◦mg 
versus placebo, and 2) BMS-986263 45◦mg versus placebo. If the first comparison is not 
statistically significant, then the second comparison will be treated as descriptive in nature.
Secondary 
Endpoints: No adjustment will be made for multiplicity for 
secondary 
 endpoints. Secondary 
 endpoints will be analyzed in a 
similar method as the primary endpoint unless otherwise specified in the SAP.
Selected continuous endpoints will be characterized using descriptive statistics and may be 
analyzed by analysis of covariance methods and/or by a mixed model for repeated measurements. 
Treatment differences at prespecified time points will be estimated using least squares means. Full 
details regarding this model and covariance structure will be provided in the SAP.
Categorical endpoints will be summarized using counts and percentages and when appropriate,
may be analyzed using categorical analysis methods.

The stratified log-rank test and Kaplan-Meier estimate may be used to analyze time-to-event 
endpoints and will be specified in the SAP.
Subgroup analyses may be performed as specified in the SAP.
10.4.2
Safety Analyses
Safety analyses will be performed using the safety population. For analysis, all treatment-emergent 
AEs recorded that occur during the conduct of the study will be listed and summarized by system 
organ class, preferred term, and treatment. Vital signs and clinical laboratory test results will be 
listed and summarized by treatment. ECG readings will be evaluated by the investigator and 
abnormalities, if present, will be summarized and listed.
Safety assessments include incidences of AEs, SAEs, and AESI (Section 9.2), AEs leading to 
discontinuation, and death, as well as marked abnormalities in clinical laboratory tests, vital sign 
measurements, ECGs, physical examinations, and change in BMD collected by DXA scan from 
baseline to Follow-up Week 24. Furthermore, the occurrence of IRRs will be analyzed as a 
function of the infusion rates and compared between treatment groups.

PK
PK
 of BMS-986263 will be analyzed based on the time points indicated in
 Plasma concentrations of the components of the LNP, such as DPD, S104, and HEDC
will also be measured.
PK evaluation is a secondary endpoint. Plasma concentrations of siRNA, DPD, HEDC, and S104 
(components of BMS-986263 for injection) will be listed and summarized descriptively by dose, 
day, and time.
Analysis of PK and exposure-response relationships of BMS-986263 will be conducted using a 
population approach as appropriate and reported separately from the CSR.

Week 12 Analyses
After all participants have either completed the Follow-up Week 4 visit or have discontinued the 
study prior to the Follow-up Week 4 visit, the study will be unblinded and the primary analysis for 
the study will be conducted.
10.4.5
Interim Analysis
Two interim analyses may be performed after approximately 30% and 50% of participants have 
either completed the Follow-up Week 4 visit or have discontinued the study prior to the Follow-
up Week 4 visit. 
The purpose of the 30% interim analyses will be to assess futility. The DMC will review the 
available data to make recommendation on the following options: 

Continue the study as planned

Terminate the study for futility
The futility decision criteria and the review process by the DMC will be specified in the DMC 
Charter and the DMC SAP.
The purpose of the 50% interim analysis will be to help in early planning for accelerating further 
clinical development of the compound. No formal test of statistical significance is planned. Results 
will be descriptive and based on the estimation of effect size and associated CIs. Thus, no 
adjustments to overall Type I error will be made.
The interim analysis results on both occasions will be reviewed by the independent DMC; and the 
Sponsor’s Internal Review Committee (IRC) if needed. The blinding to investigators and the study 
team will be maintained until the end of the study.
Within the DMC Charter, for each interim analysis, the Sponsor will specify:

Conditions under which interim results could be shared with select individuals within BMS to 
help in early planning of clinical development of the compound

Steps taken to ensure the blinding of the other BMS personnel (that are not unblinded) and 
investigators to interim results

Statistical summaries that will be prepared for review
Details of the interim analyses will be described in the DMC SAP and DMC Charter, which will 
be revised and finalized prior to the DMC meeting.

COMPLIANCE WITH THE PROTOCOL AND PROTOCOL REVISIONS
The investigator should not implement any deviation or change to the protocol without prior 
review and documented approval/favorable opinion of an amendment from the IRB/IEC (and if 
applicable, also by local Health Authority) except where necessary to eliminate an immediate 
hazard(s) to study subjects/participants.
If a deviation or change to a protocol is implemented to eliminate an immediate hazard(s) prior to 
obtaining relevant approval/favorable opinion(s) the deviation or change will be submitted, as soon 
as possible to:

IRB/IEC for

Regulatory Authority(ies), if applicable by local regulations (per national requirements)
Documentation of approval/favorable opinion signed by the chairperson or designee of the 
IRB(s)/IEC(s) and if applicable, also by local Health Authority must be sent to BMS.
If an amendment substantially alters the study design or increases the potential risk to the 
participant: (1) the consent form must be revised and submitted to the IRB(s)/IEC(s) for review 
and approval/favorable opinion; (2) the revised form must be used to obtain consent from 
subjects/participants currently enrolled in the study if they are affected by the amendment; and 
(3) the new form must be used to obtain consent from new subjects/participants prior to 
enrollment.
If the revision is done via an administrative letter, investigators must inform their IRB(s)/IEC(s).
FINANCIAL DISCLOSURE
Investigators and subinvestigators will provide the Sponsor with sufficient, accurate financial 
information in accordance with local regulations to allow the Sponsor to submit complete and 
accurate financial certification or disclosure statements to the appropriate Health Authorities. 
Investigators are responsible for providing information on financial interests during the course of 
the study and for 1 year after completion of the study.
INFORMED CONSENT PROCESS
Investigators must ensure that subjects/participants are clearly and fully informed about the 
purpose, potential risks, and other critical issues regarding clinical studies in which they volunteer 
to participate.
In situations where consent cannot be given to subjects/participants, their legally acceptable 
representatives (as per country guidelines) are clearly and fully informed about the purpose, 
potential risks, and other critical issues regarding clinical studies in which the participant 
volunteers to participate.
Sponsor or designee will provide the investigator with an appropriate (ie, Global or Local) sample 
informed consent form (ICF) which will include all elements required by ICH, GCP, and 
applicable regulatory requirements. The sample ICF will adhere to the ethical principles that have 
their origin in the Declaration of Helsinki.

Investigators must:

Provide a copy of the consent form and written information about the study in the language in 
which the participant is most proficient prior to clinical study participation. The language must 
be nontechnical and easily understood.

Allow time necessary for participant or participant's legally acceptable representative to 
inquire about the details of the study.

Obtain an informed consent signed and personally dated by the participant or the participant's 
legally acceptable representative and by the person who conducted the informed consent 
discussion.

Obtain the IRB/IEC’s written approval/favorable opinion of the written ICF and any other 
information to be provided to the subjects/participants, prior to the beginning of the study, and 
after any revisions are completed for new information.
If informed consent is initially given by a participant’s legally acceptable representative or legal 
guardian, and the participant subsequently becomes capable of making and communicating his or 
her informed consent during the study, consent must additionally be obtained from the participant.
Revise the informed consent whenever important new information becomes available that is 
relevant to the participant's consent. The investigator, or a person designated by the investigator, 
should fully inform the participant or the participant's legally acceptable representative or legal 
guardian, of all pertinent aspects of the study and of any new information relevant to the 
participant's willingness to continue participation in the study. This communication should be 
documented.
The confidentiality of records that could identify subjects/participants must be protected, 
respecting the privacy and confidentiality rules applicable to regulatory requirements, the 
subjects'/participants’ signed ICF and, in the US, the subjects’/participants’ signed Health 
Insurance Portability and Accountability Act Authorization.
The consent form must also include a statement that BMS and regulatory authorities have direct 
access to participant records.
The rights, safety, and well-being of the study subjects/participants are the most important 
considerations and should prevail over interests of science and society.
SOURCE DOCUMENTS
The investigator is responsible for ensuring that the source data are accurate, legible, 
contemporaneous, original, and attributable, whether the data are hand-written on paper or entered 
electronically. If source data are created (first entered), modified, maintained, archived, retrieved, 
or transmitted electronically via computerized systems (and/or any other kind of electronic 
devices) as part of regulated clinical trial activities, such systems must be compliant with all 
applicable laws and regulations governing use of electronic records and/or electronic signatures. 
Such systems may include, but are not limited to, electronic medical/health records (EMRs/EHRs), 
adverse event (AE) tracking/reporting, protocol-required assessments, and/or drug accountability

CASE REPORT FORMS
An investigator is required to prepare and maintain adequate and accurate case histories designed 
to record all observations and other data pertinent to the investigation on each individual treated 
or entered as a control in the investigation. Data that are derived from source documents and 
reported on the case report form (CRF) must be consistent with the source documents or the 
discrepancies must be explained. Additional clinical information may be collected and analyzed 
in an effort to enhance understanding of product safety. CRFs may be requested for AEs and/or 
laboratory abnormalities that are reported or identified during the course of the study.
For sites using the Sponsor or designee electronic data capture tool, electronic CRFs will be 
prepared for all data collection fields except for fields specific to SAEs and pregnancy, which will 
be reported on the electronic SAE form and paper Pregnancy Surveillance Form, respectively. If 
electronic SAE form is not available, a paper SAE form can be used.
The confidentiality of records that could identify subjects/participants must be protected, 
respecting the privacy and confidentiality rules in accordance with the applicable regulatory 
requirement(s).
The investigator will maintain a signature sheet to document signatures and initials of all persons 
authorized to make entries and/or corrections on CRFs.
The completed CRF, SAE/pregnancy CRFs, must be promptly reviewed, signed, and dated by the 
investigator or qualified physician who is a subinvestigator and who is delegated this task on the 
Delegation of Authority Form. Subinvestigators in Japan may not be delegated the CRF approval 
task. For electronic CRFs, review and approval/signature is completed electronically through the 
electronic data capture tool. The investigator must retain a copy of the CRFs including records of 
the changes and corrections.
Each individual electronically signing electronic CRFs must meet Sponsor or designee training 
requirements and must only access the electronic data capture tool using the unique user account

provided by Sponsor or designee. User accounts are not to be shared or reassigned to other 
individuals.
MONITORING
Sponsor or designee representatives will review data centrally to identify potential issues to 
determine a schedule of on-site visits for targeted review of study records.
Representatives of BMS must be allowed to visit all study site locations periodically to assess the 
data quality and study integrity. On site they will review study records and directly compare them 
with source documents, discuss the conduct of the study with the investigator, and verify that the 
facilities remain acceptable. Certain eCRF pages and/or electronic files may serve as the source 
documents:
In addition, the study may be evaluated by Sponsor or designee internal auditors and government 
inspectors who must be allowed access to eCRFs, source documents, other study files, and study 
facilities. BMS audit reports will be kept confidential.
The investigator must notify BMS promptly of any inspections scheduled by regulatory authorities, 
and promptly forward copies of inspection reports to Sponsor or designee.
RECORDS RETENTION
The investigator (or head of the study site in Japan) must retain all study records and source 
documents for the maximum period required by applicable regulations and guidelines, or 
institution procedures, or for the period specified by BMS or designee, whichever is longer. The 
investigator (or head of the study site in Japan) must contact BMS prior to destroying any records 
associated with the study.
BMS or designee will notify the investigator (or head of the study site in Japan) when the study 
records are no longer needed.
If the investigator withdraws from the study (eg, relocation, retirement), the records shall be 
transferred to a mutually agreed upon designee (eg, another investigator, study site, IRB). Notice 
of such transfer will be given in writing to BMS or designee.
RETURN OF STUDY TREATMENT
For this study, study treatments (those supplied by BMS, a vendor or sourced by the investigator) 
such as partially used study treatment containers, vials, and syringes may be destroyed on-site.

APPENDIX 3
ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS: 
DEFINITIONS AND PROCEDURES FOR RECORDING, 
EVALUATING, FOLLOW-UP, AND REPORTING
ADVERSE EVENTS
AE Definition
An AE is defined as any new untoward medical occurrence or worsening of a preexisting 
medical condition in a clinical investigation participant administered study drug and that does 
not necessarily have a causal relationship with this treatment. 
An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of study drug, whether or not 
considered related to the study drug.
Events Meeting the AE Definition

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
results from other safety assessments (eg, electrocardiogram [ECG], radiological scans, 
vital signs measurements), including those that worsen from baseline, considered clinically 
significant in the medical and scientific judgment of the investigator. Note that abnormal 
lab tests or other safety assessments should only be reported as AEs if the final diagnosis is 
not available. Once the final diagnosis is known, the reported term should be updated to be 
the diagnosis.

Exacerbation of a chronic or intermittent preexisting condition including either an increase 
in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study intervention administration even though 
it may have been present before the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
intervention or a concomitant medication. Overdose, as a verbatim term (as reported by the 
investigator), should not be reported as an AE/SAE unless it is an intentional overdose 
taken with possible suicidal/self-harming intent. Such overdoses should be reported 
regardless of sequelae and should specify “intentional overdose” as the verbatim term.
Events NOT Meeting the AE Definition

Medical or surgical procedure (eg, endoscopy, appendectomy): the condition that leads to 
the procedure is the AE.

Situations in which an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

DEFINITION OF SAE
If an event is not an AE per definition above, then it cannot be an SAE even if serious conditions 
are met.
SERIOUS ADVERSE EVENTS
SAE Definition is defined as any untoward medical occurrence that, at any dose:
Results in death
Is life-threatening (defined as an event in which the participant was at risk of death at the time 
of the event; it does not refer to an event which hypothetically might have caused death if it 
were more severe)
Requires inpatient hospitalization or causes prolongation of existing hospitalization (see note 
below)
NOTE: The following hospitalizations are not considered SAEs in BMS clinical studies:

a visit to the emergency room or other hospital department < 24 hours, that does not result 
in admission (unless considered an important medical or life-threatening event)

elective surgery, planned prior to signing consent

admissions as per protocol for a planned medical/surgical procedure

routine health assessment requiring admission for baseline/trending of health status (eg, 
routine colonoscopy)

medical/surgical admission other than to remedy ill health and planned prior to entry into 
the study. Appropriate documentation is required in these cases

admission encountered for another life circumstance that carries no bearing on health status 
and requires no medical/surgical intervention (eg, lack of housing, economic inadequacy, 
caregiver respite, family circumstances, administrative reason)

admission for administration of anticancer therapy in the absence of any other SAEs 
(applies to oncology protocols)
Results in persistent or significant disability or permanent damage
Is a congenital anomaly/birth defect
Is an important medical event (defined as a medical event(s) that may not be immediately 
life-threatening or result in death or hospitalization but, based upon appropriate medical and 
scientific judgment, may jeopardize the participant or may require intervention [eg, medical, 
surgical] to prevent one of the other serious outcomes listed in the definition above). Examples 
of such events include, but are not limited to, intensive treatment in an emergency room or at 
home for allergic bronchospasm; blood dyscrasias, or convulsions that do not result in 
hospitalization. Potential drug-induced liver injury (DILI) is also considered an important 
medical event (see Section 9.2.7 for the definition of potential DILI).

Pregnancy and potential DILI must follow the same transmission timing and processes to BMS 
as used for SAEs (see Section 9.2.5 for reporting pregnancies).
EVALUATING AES AND SAES
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE reported 
during the study and assign it to 1 of the following categories: 

Mild: An event that is easily tolerated by the subject/participant, causing minimal 
discomfort, and not interfering with everyday activities.

Moderate: An event that causes sufficient discomfort and interferes with normal 
everyday activities.

Severe: An event that prevents normal everyday activities. An AE that is assessed as 
severe should not be confused with an SAE. Severe is a category utilized for rating 
the intensity of an event; and both AEs and SAEs can be assessed as severe.
An event is defined as “serious” when it meets at least 1 of the predefined outcomes as 
described in the definition of an SAE, NOT when it is rated as severe.
Assessment of Causality

The investigator is obligated to assess the relationship between study intervention and 
each occurrence of each AE/SAE. A “reasonable possibility of a relationship” 
conveys that there are facts, evidences, and/or arguments to suggest a causal 
relationship rather than a relationship cannot be ruled out.

The investigator will use clinical judgment to determine the relationship.

Alternative causes, such as underlying disease(s), concomitant therapy, and other risk 
factors, as well as the temporal relationship of the event to study intervention 
administration will be considered and investigated.

The investigator will also consult the Investigator’s Brochure and/or Product 
Information, for marketed products, in his/her assessment.

For each AE/SAE, the investigator must document in the medical notes that he/she 
has reviewed the AE/SAE and has provided an assessment of causality.

There may be situations in which an SAE has occurred and the investigator has 
minimal information to include in the initial report to Sponsor. However, it is very 
important that the investigator always make an assessment of causality for every event 
before the initial transmission of the SAE data to Sponsor.

The investigator may change his/her opinion of causality in light of follow-up 
information and send a SAE follow-up report with the updated causality assessment.

The causality assessment is one of the criteria used when determining regulatory 
reporting requirements.

Follow-up of AEs and SAEs
If only limited information is initially available, follow-up reports are required. Note: 
Follow-up SAE reports must include the same investigator term(s) initially reported.
If an ongoing SAE changes in its intensity or relationship to study drug or if new 
information becomes available, the SAE report must be updated and submitted within
24 hours to BMS (or designee) using the same procedure used for transmitting the initial 
SAE report.
All SAEs must be followed to resolution or stabilization.
REPORTING OF SAES TO SPONSOR OR DESIGNEE
SAEs, whether related or not related to study drug, and pregnancies must be reported 
immediately to BMS (or designee) but no later than 24 hours of awareness of the event.
SAEs must be recorded on the SAE Report Form. For studies capturing SAEs through 
electronic data capture, electronic submission is the required method for reporting. In the 
event the electronic system is unavailable for transmission, paper forms must be used and 
submitted immediately. When paper forms are used, the original paper forms are to 
remain on-site.
Pregnancies must be recorded on a paper Pregnancy Surveillance Form and transmitted 
via email or confirmed facsimile (fax) transmission to:
SAE Email Address: Refer to Contact Information list.
SAE Fax Number: Refer to Contact Information list.
SAE Telephone Contact - For questions on SAE/pregnancy reporting: Refer to

WOMEN OF CHILDBEARING POTENTIAL DEFINITIONS AND 
METHODS OF CONTRACEPTION
DEFINITIONS
Woman of Childbearing Potential (WOCBP)
A woman is considered fertile following menarche and until becoming postmenopausal unless 
permanently sterile. Permanent sterilization methods include hysterectomy, bilateral 
salpingectomy, and bilateral oophorectomy.
Women in the following categories are not considered WOCBP

Premenarchal

Premenopausal female with 1 of the following:

Documented hysterectomy

Documented bilateral salpingectomy

Documented bilateral oophorectomy
Note: Documentation can come from the site personnel’s review of the participant’s medical 
records, medical examination, or medical history interview.

Postmenopausal female

A postmenopausal state is defined as 12 months of amenorrhea in a woman over age 
45 years in the absence of other biological or physiological causes. In addition, female 
participants under the age of 55 years must have a serum follicle-stimulating hormone 
(FSH) level > 40 mIU/mL to confirm menopause.
Note: Female participants treated with hormone replacement therapy (HRT) are likely to have 
artificially suppressed FSH levels and may require a washout period in order to obtain a 
physiologic FSH level. The duration of the washout period is a function of the type of HRT used. 
The duration of the washout period below are suggested guidelines and the investigators should 
use their judgment in checking serum FSH levels.

1 week minimum for vaginal hormonal products (rings, creams, gels)

4 week minimum for transdermal products

8 week minimum for oral products
Other parenteral products may require washout periods as long as 6 months. If the serum FSH 
level is > 40 mIU/mL at any time during the washout period, the woman can be considered 
postmenopausal.
End of Relevant Systemic Exposure
End of relevant systemic exposure is the time point where the IMP or any active major metabolites 
has decreased to a concentration that is no longer considered to be relevant for human 
teratogenicity or fetotoxicity. This should be evaluated in context of safety margins from the 
no-observed-adverse-effect level or the time required for 5 half-lives of the IMP to pass.

METHODS OF CONTRACEPTION
Local laws and regulations may require use of alternative and/or additional contraception methods.
Highly Effective Contraceptive Methods That Are User Dependent
Failure rate of < 1% per year when used consistently and correctly.a

Combined (estrogen- and progestogen-containing) hormonal contraception associated with 
inhibition of ovulation and/or implantation (This method of contraception can only be used 
by WOCBP participants in studies where hormonal contraception is permitted by the study 
protocol)b

oral (birth control pills)

intravaginal (vaginal birth control suppositories, rings, creams, gels)

transdermal

Combined (estrogen-and progestogen-containing) hormonal contraception must begin at 
least 30 days prior to initiation of study therapy

Progestogen-only hormonal contraception associated with inhibition of ovulation (This 
method of contraception can only be used by WOCBP participants in studies where 
hormonal contraception is permitted by the study protocol)b

oral

injectable

Progestogen-only hormonal contraception must begin at least 30 days prior to initiation of 
study therapy
Highly Effective Methods That Are User Independent

Implantable progestogen-only hormonal contraception associated with inhibition of 
ovulation and/or implantation (This method of contraception can only be used by WOCBP 
participants in studies where hormonal contraception is permitted by the study protocol)b

Intrauterine device (IUD)c

Intrauterine hormone-releasing system (This method of contraception can only be used by 
WOCBP participants in studies where hormonal contraception is permitted by the study 
protocol)b,c

Bilateral tubal occlusion

Vasectomized partner
Having a vasectomized partner is a highly effective contraception method provided that the 
partner is the sole male sexual partner of the WOCBP and the absence of sperm has been 
confirmed. If not, an additional highly effective method of contraception should be used.
Male participants will be required to always use a latex or other synthetic condom during 
any sexual activity (eg, vaginal, anal, oral) with WOCBP; even if the participants have 
undergone a successful vasectomy or if their partner is already pregnant or breastfeeding.


Sexual abstinence
Sexual abstinence is considered a highly effective method only if defined as refraining from 
heterosexual intercourse during the entire period of risk associated with the study treatment. 
The reliability of sexual abstinence needs to be evaluated in relation to the duration of the 
study and the preferred and usual lifestyle of the participant.

Continuous abstinence must begin at least 30 days prior to initiation of study therapy.

It is not necessary to use any other method of contraception when complete abstinence is 
elected.

WOCBP participants who choose complete abstinence must continue to have pregnancy 
tests, as specified in the Schedule of Activities, Section 2.

Acceptable alternate methods of highly effective contraception must be discussed in the 
event that the WOCBP participants chooses to forego complete abstinence.

Periodic abstinence (including but not limited to calendar, symptothermal, postovulation 
methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea 
method (LAM) are not acceptable methods of contraception for this study.
NOTES:
a Typical use failure rates may differ from those when used consistently and correctly. Use 
should be consistent with local regulations regarding the use of contraceptive methods for 
participants participating in clinical studies.
b Hormonal contraception may be susceptible to interaction with the study treatment, which 
may reduce the efficacy of the contraceptive method. Hormonal contraception is permissible 
only when there is sufficient evidence that the IMP and other study medications will not alter 
hormonal exposures such that contraception would be ineffective or result in increased 
exposures that could be potentially hazardous. In this case, alternative methods of 
contraception should be utilized.
c Intrauterine hormone-releasing systems are acceptable methods of contraception in the 
absence of definitive drug interaction studies when hormone exposures from intrauterine 
devices do not alter contraception effectiveness
Less Than Highly Effective Contraceptive Methods That are User Dependent
Failure rate of > 1% per year when used consistently and correctly.

Male or female condom with or without spermicide. Male and female condoms cannot be 
used simultaneously

Diaphragm with spermicide

Cervical cap with spermicide

Vaginal Sponge with spermicide

Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the 
primary mechanism of action (This method of contraception cannot be used by WOCBP 
participants in studies where hormonal contraception is prohibited.)

PROTOCOL AMENDMENT SUMMARY OF CHANGE HISTORY
Overall Rationale for the Revised Protocol 02, 25-Nov-2020
The primary purpose of this Global Revised Protocol is to expand the patient population from 
Child-Pugh A5 to Child-Pugh A6, including corresponding laboratory exclusion criteria, based on 
preliminary results from hepatic impairment (HI) study IM025015. Key secondary revisions 
include the following:

Adding results from Part 1 of HI study IM025015, which supports the changes in Child-
Pugh/laboratory exclusion criteria

Adjustment of step-wise infusion rates (decreased number of steps)

Adding guidance 
 related to the coronavirus disease 2019 
(COVID-19) pandemic

Changing statistical sample size calculation, study stratification factors, and statistical analysis 
methodology for primary endpoint

Excluding participants from the study who are taking anticoagulants

Replacing liver ultrasound as a screening procedure for detection of hepatocellular carcinoma 
(HCC) with multiphasic liver computed tomography (CT)/magnetic resonance imaging (MRI)

Updating exclusion criterion related to history of weight gain/loss

Updating exclusion criterion related to history of illegal intravenous (IV) drug use

Adding option for participants who have a prolonged international normalized ratio (INR) 
and/or lower platelet count to potentially receive treatments for coagulation abnormalities 
and/or low platelet counts prior to liver biopsy
All changes applied to the body were applied to the synopsis, as necessary; synopsis changes are 
not included in the list below.
Only major additions and deletions are provided in this summary; all minor grammatical, 
formatting, rephrasing, stylistic changes, or clarifications are not included.

Description of Change
Brief Rationale
9.1.2 Liver Biopsy 
Assessments
Added the following text:
Participants who have a 
prolonged INR and/or lower 
platelet count may receive 
treatments to correct 
coagulation abnormalities 
and/or low platelet counts prior 
to liver biopsy based on 
investigator’s clinical 
judgment in order to reduce the 
risk of bleeding. It is the 
investigator’s responsibility to 
assess any potential risks that 
may be associated with the use 
of these agents (eg, transfusion 
of fresh/frozen plasma or 
platelets).
Added to allow investigators to 
administer treatments to 
correct abnormal INR or 
platelets prior to liver biopsy, 
in order to reduce the risk of 
bleeding associated with the 
liver biopsy, based on 
investigator’s assessment of 
the benefits-risks of these 
treatments.
10.1 Sample Size 
Determination
Participant dropout rate 
changed from 10% to 6% and 
evaluable number of 
participants changed from 79

size of approximately 
270 participants.
10.1 Sample Size 
Determination

Chi-Square test
The CMH test is no longer 
applicable to justify the sample 
size, as the final analysis was 
changed from CMH to logistic 
regression. Treatment group 
comparisons using the logistic 
regression model are

Overall Rationale for the Revised Protocol 01, 27-May-2020
The primary purpose of this Global Revised Protocol is to adjust an inclusion criterion for 
participants without steatohepatitis (to add a biopsy-based requirement). Key secondary revisions 
include the following:

Correcting an exclusion criterion-related equation for estimated glomerular filtration rate, now 
replaced by literature reference

Adding nintedanib as a concomitant medication restriction

Adding/clarifying statistical analysis methods for primary and secondary
 efficacy 
endpoints

Updating interim analyses to include a single analysis only

Incorporating changes previously provided in country-specific amendments and an 
administrative letter

Updating sections to align with current protocol template

Updating background clinical study data

Adding the recommended stepped infusion rates for study treatment

Adding required urine pregnancy test prior to visits in which dual-energy X-ray absorptiometry 
is conducted

Clarifying study exclusion exceptions related to Child-Pugh exclusion criterion

Specifically referencing an Independent Pathology Review Committee and respective charter 
to be utilized in the study

Adding an appendix for exclusion of human immunodeficiency virus positive participants 
where locally required

Section Number & Title
Description of Change
Brief Rationale
4.1.3 DMC and Other 
External Committees
Referenced the utilization of an 
IPRC and respective charter in 
the study
Original protocol referenced a 
central pathologist; this change 
is to reflect use of a pathology 
review committee.
5.1 Inclusion Criteria
2) Type of Participant 
and Target Disease 
Characteristics
Replaced as follows:
2)a) → 2)e)
Revised to clarify liver biopsy 
inclusion criteria for subjects 
without definite steatohepatitis.

3) Age and reproductive 
status
Replaced as follows:

3)a)b → 3)a)e

3)a)d → 3)a)f

3)b)c → 3)b)i

3)b)d → 3)b)j


3) Prior and concomitant 
therapy
6.7.1 Prohibited and/or 
Restricted Treatments
Added nintedanib as a 
concomitant medication 
restriction [added as 3)f)]

SUMMARY OF KEY CHANGES TO THE REVISED PROTOCOL 01
Section Number & Title
Description of Change
Brief Rationale
9.4.1 Efficacy Analyses/
Primary Endpoint
Replaced Chi-square test with 
Cochran-Mantel-Haenszel test 
stratified by randomization 
strata to test the difference in 
distribution of response rate 
among 3 treatment groups, and 
specified test significance level 
prompting pairwise 
comparisons to placebo
The Chi-square test does not 
specifically allow for adjusting 
for randomized strata; the 
Cochran-Mantel-Haenszel test 
does allow for this adjustment.
9.4.1 Efficacy Analyses/
Secondary 
 
Endpoints
Added mixed model for 
repeated measurements
Added additional statistical 
analysis option for continuous 
secondary 
 
endpoints.
9.4.5 Interim Analysis
Removed first interim analysis 
(after approximately 30% of 
participants completed the 
Follow-up Week 4 
visit/discontinued prior to this 
visit) and specified contents of 
the DMC Charter related to 
interim analysis
To reduce the number of 
interim analyses performed in 
the study, this analysis will 
only be conducted one time, 
when 50% of participants have 
completed Follow-up Week 4.
Appendix 8 
Country-specific 
Requirements
Added appendix
Added to indicate changes to 
be made to appropriate 
protocol sections related to 
participants who are HIV 
positive in countries in which 
it is locally mandated that such 
patients be excluded.
