SYNOPSIS
Protocol Title: A Phase 2 Randomized, Double-Blind, Placebo-Controlled Study of the Safety 
and Efficacy of BMS-986165 in Subjects with Moderate to Severe Crohn's Disease
Study Phase: 2
Background: 
Tyrosine kinase 2 (TYK2) is a protein involved in interleukin (IL)-12, IL-23 and Type I interferon 
(IFN) signaling, and it is required for the activation of downstream signaling pathways. TYK2 is 
a widely expressed, non-receptor tyrosine kinase that catalyzes the phosphorylation of signal 
transducer and activator of transcription (STAT) proteins downstream of the receptors for the p40-
containing cytokines IL-12 and IL-23, as well as the Type I interferon receptor. This results in the 
activation of STAT-dependent transcription and functional responses specific for these cytokines. 
TYK2-dependent cytokines (eg, IL-12, IL-23 and Type I IFNs) are distinct from those dependent 
on closely related Janus kinase (JAK) family members JAK1 and JAK3 (eg, IL-2, IL-6, IL-7, IL-
15) or JAK2 (eg, erythropoietin, thrombopoietin, and granulocyte-monocyte colony-stimulating 
factor). Consequently, a TYK2 inhibitor is expected to have a highly differentiated profile from 
inhibitors of other JAK family kinases. TYK2-dependent pathways and the cytokine networks they 
modulate (eg, IL-23, IL-17, IFNα) have been implicated in the pathophysiology of multiple 
immune-mediated diseases, including Crohn’s disease (CD), ulcerative colitis, psoriasis, psoriatic 
arthritis, systemic lupus erythematosus (SLE) and spondyloarthritides. 
BMS-986165 is an orally administered selective TYK2 inhibitor. A comprehensive in vitro and 
in vivo characterization of BMS-986165 has been established and supports the development of 
this compound in humans. Inhibition of TYK2 is expected to provide therapeutic benefit for 
patients with CD for multiple reasons: 1) IL-12 and IL-23 have been implicated in pathogenesis 
of CD; 2) Biologic agents targeting IL-23p19 and IL-12/23p40 cytokines have been shown to be 
efficacious in CD, and ustekinumab targeting IL-12/23p40 has been approved for the treatment of 
CD; and 3) BMS-986165 has been shown to be efficacious in psoriasis, an IL-23-mediated disease, 
in a recent Phase 2 study.
Overview of Study Design: 
IM011023 is a Phase 2 randomized, double-blind, placebo-controlled clinical study designed to 
assess the safety and efficacy of BMS-986165 compared to placebo in subjects with moderately 
to severely active CD. 
Approximately 240 subjects will be randomized in this study. After a 28-day Screening Period, 
eligible subjects will be randomized in a 3:3:2 ratio to one of three study arms: (i) BMS-986165 
6 mg twice daily (BID) by mouth (PO); n≈90, (ii) BMS-986165 3 mg BID PO; n≈90, or 
(iii) matched placebo; n≈60.

Clinical Protocol
IM011023
BMS-986165
TYK2 Inhibitor
This study has a 12-week double-blind Induction Period, a 40-week double-blind Maintenance 
Period, and a 52-week Open-label Extension (OLE) Period, leading to a total of up to 104 weeks 
of exposure to investigational product (IP). The primary efficacy assessment occurs at Week 12. 
The co-primary endpoints are defined as achieving clinical remission (defined as Crohn’s Disease 
Activity Index [CDAI] of < 150) and achieving endoscopic response (≥50% improvement from 
baseline in the Simple Endoscopic Score for Crohn’s Disease [SES-CD]), on a population basis, 
at Week 12.
This study has a treat-through design in order to explore sustained clinical benefit and safety in the 
Maintenance Period. Subjects who achieve clinical response (a reduction from baseline in the 
CDAI score of ≥100 points or a total CDAI score < 150) at Week 12 (Day 85), are eligible to enter 
the Maintenance Period and to continue on the same double-blind treatment regimen that they 
received in the Induction Period for up to an additional 40 weeks, up to Week 52. Subjects with a 
loss of response (LOR; an increase in the CDAI score of ≥100 points compared to Week 12 and 
a total CDAI score of ≥220 points) at any time from Week 13 through Week 52 are eligible to 
enter an open-label BMS-986165 6 mg BID PO arm through Week 52. 
Subjects who do not achieve clinical response at Week 12 and who have an appropriate safety 
profile are eligible to enter an open-label BMS-986165 6 mg BID PO arm, in which clinical 
response is again assessed at Week 26 (compared to Week 0). Subjects in this open-label study 
arm who achieve clinical response at Week 26 (compared to Week 0) may continue in this arm 
through Week 52. Subjects in this open-label study arm who do not achieve clinical response at 
Week 26 (compared to Week 0) will be considered treatment failures and must permanently 
discontinue IP and enter the Post-treatment Follow-up Period. Throughout the study, subjects who 
permanently discontinue IP prior to Week 52 must enter the Post-treatment Follow-up Period. 
Subjects who continue to derive a clinical benefit from IP at Week 52, as judged by the 
investigator, are eligible to enter the OLE Period. The OLE Period lasts 52 weeks, to Week 104.
Overview of Scientific Rationale:
The scientific rationale for the study is summarized above and further detailed in Section 3 and the 
Investigator Brochure (IB). This Phase 2 randomized, double-blind clinical trial is designed to 
assess the safety and efficacy of BMS-986165 in patients with moderately to severely active CD.

 Section 3.2.3, 
 
Study Population: 
The study population includes male and female subjects, 18 to 75 years old (inclusive), with a 
documented diagnosis of CD for at least 3 months prior to screening. The diagnosis must be 
confirmed with source document evidence of a colonoscopy with ileal intubation (ileo-
colonoscopy) and histopathology showing features consistent with CD. Subjects with ileal, 
colonic, or ileocolonic disease distribution are eligible to participate in the study. Subjects with 
perianal fistulizing disease are eligible to participate in the study, provided they meet the other 
inclusion/exclusion criteria, eg, subjects with a current abscess or suspected abscess are excluded.
Subjects must have an inadequate response, LOR, or intolerance to a standard treatment course of 
either conventional therapy (eg, 5-ASAs, corticosteroids, immunomodulators) or biologic therapy 
(eg, infliximab, adalimumab, certolizumab pegol, vedolizumab, natalizumab, or ustekinumab) for 
CD.
A subject will be considered enrolled only when the informed consent form (ICF) is signed. 
Subjects must have clinical and endoscopic evidence of moderately to severely active CD, as 
evidenced by the following minimum disease activity criteria, assessed during the Screening 
Period:

a Subjects who achieve clinical response at Week 12 can enter the OL “loss of response” arm at any time from 
Week 13 through Week 52. Loss of response is defined as an increase in the CDAI score of ≥ 100 points compared 
to Week 12, and a total CDAI score of ≥ 220.
NOTE: This study has a treat-through design. At Week 12, subjects who achieve clinical response (defined as a 
reduction from baseline in the CDAI score of ≥100 points or a total CDAI score < 150) are eligible to continue to the 
Maintenance Period, where they will continue to receive the double-blind treatment regimen that they received in the 
Induction Period. Subjects who have loss of response in these arms may be eligible to enter the loss of response arm, 
where they will receive open-label BMS-986165 6 mg BID PO through Week 52. Subjects who do not achieve clinical 
response at Week 12 and who have an appropriate safety profile are eligible to enter an open-label treatment arm, in 
which they will receive open-label BMS-986165 6 mg BID PO during the Maintenance Period. Subjects in this arm

Subjects who were randomized when earlier versions of the protocol (Protocol v1.0 [27-Mar-2018] 
or Protocol v2.0 [24-May-2018]) were in effect will continue on their currently assigned 
double-blind study treatment. These subjects will complete all study procedures and assessments 
outlined in the current version  of the protocol.
Number of Subjects: 
Approximately 240 subjects will be randomized in a 3:3:2 ratio to receive BMS-986165 6 mg BID, 
BMS-986165 3 mg BID, or placebo BID, resulting in approximately 90 subjects per BMS-986165 
dose arm and 60 subjects in the placebo arm during the Induction Period. 
Treatment Arms and Duration:
The total duration of study participation will be up to approximately 112 weeks (784 days) in 
5 periods including up to a 4-week (28-day) Screening Period, a 12-week (84-day) Induction 
Period, a 40-week (280 day) Maintenance Period, a 52-week (364-day) OLE Period, and a 4-week 
(28-day) Post-treatment Follow-up Period. The total exposure to IP in this study will be up to 
104 weeks.
In all treatment groups, subjects will take their randomly assigned treatment twice daily as oral 
capsules.

Screening Period (up to 28 days duration):
The purpose of the Screening Period is to determine if a subject meets the enrollment criteria for 
this clinical trial. The suggested order of screening investigations is as follows: 
(i) Screening visit in order to sign the ICF and then obtain a medical history, vital signs and 
physical examination, screening blood tests, chest x-ray, ECG, etc, give the subject the electronic 
study diary and train on the diary, and schedule the screening ileocolonoscopy and Week 0 visit. 
Sites should consider the turnaround time for the centrally read endoscopy result when scheduling 
the ileocolonoscopy and Week 0 visits.
(ii) The subject will then record up to 14 days of daily diary data at home, in order to facilitate 
CDAI and PRO2 calculation. The minimum daily diary requirements for CDAI/PRO2 calculation 
are outlined in Section 9.1. In order to ensure that a subject can be successfully randomized, sites 
should consider periodically confirming that subjects are successfully entering and uploading daily 
diary data. See Section 9.1, APPENDIX 10, and
 for more details.
(iii) Sites should check the results of screening investigations to confirm that a subject remains 
potentially eligible for inclusion before a subject commences bowel preparation for the screening 
ileocolonoscopy.
(iv) The screening ileocolonoscopy will be performed. Subjects should be randomized within 
14 days of the screening ileocolonoscopy.
Induction Period (Weeks 0 through 12): 
During the Induction Period, subjects will take twice daily oral doses of the IP over 12 weeks 
 For each dose level, capsules are taken once in the morning and once in the evening. 
Subjects will be randomized to 1 of the 3 following treatments:
•
BMS986165 6 mg BID 
 
•
BMS986165 3 mg BID 
 
•
Placebo 
Video ileocolonoscopic examination and collection of ileal and/or colonic tissue biopsies should 
be performed within a window of 7 days prior to the Week 12 visit. The CDAI/PRO2 scores for 
determination of clinical response/remission status will be calculated as described in Section 9.1. 
In order to avoid missing data, sites should consider periodically confirming that subjects are 
successfully entering and uploading daily diary data prior to Week 12.

(i). Subjects Who Demonstrate Clinical Response at Week 12
At Week 12 (Day 85), subjects who achieve a clinical response (as defined above) and who have 
an appropriate safety profile are eligible to continue to receive the same blinded study regimen 
(BMS-986165 6 mg BID or 3 mg BID or placebo BID) during the Maintenance Period. Blinded 
study treatment will continue until these subjects have completed Week 52 (Day 365), or have 
LOR (Section 5.1.3.3), or if they permanently discontinue IP prior to Week 52 for another reason. 
Subjects who achieve a clinical response at Week 12 and subsequently have an LOR during the 
Maintenance Period and who have an appropriate safety profile are eligible to switch to open-label 
treatment with BMS 6 mg BID. Alternatively, they can be permanently discontinued from 
treatment based on subject and/or investigator preference and enter the Post-treatment Follow-up 
Period. 
(ii). Subjects With No Clinical Response at Week 12
Subjects who do not achieve a clinical response at Week 12 and who have an appropriate safety 
profile are eligible to switch to open-label BMS-986165 treatment at the highest dose (6 mg BID), 
regardless of the initial treatment regimen received during the Induction Period.
Subjects who do not achieve protocol-defined clinical response at Week 12 and are switched to 
the open-label BMS-986165 6 mg BID arm, as well as those who are currently receiving 
open-label BMS-986165 12 mg QD prior to implementation of Protocol v3.0, must be assessed 
for clinical response at Week 26. If clinical response at Week 26 (compared to Week 0) is 
achieved, and subjects have an appropriate safety profile, these subjects are eligible to continue on 
the open-label treatment for the remaining duration of the Maintenance Period. Subjects in this 
open-label study arm who do not achieve clinical response at Week 26 (compared to Week 0) will 
be considered treatment failures and must permanently discontinue IP and enter the Post-treatment 
Follow-up Period. Note: These subjects may also be discontinued at any time before Week 26 
based on the clinical judgment of the investigator.
(iii). Subjects Randomized to 12 mg QD Arm in Protocol v1.0 or Protocol v2.0
Subjects who were randomized when Protocol v1.0 (27-Mar-2018) or Protocol v2.0 
(24-May-2018) was in effect will continue on their currently assigned double-blind study 
treatment. Subjects who were randomized to BMS-986165 12 mg QD prior to the current protocol, 
and who have not yet reached Week 12 who then achieve clinical response at Week 12, with an 
appropriate safety profile, are eligible to continue on blinded 12 mg QD study treatment. Subjects 
from this cohort who do not achieve clinical response at Week 12 who have an appropriate safety 
profile are eligible to switch to open-label BMS-986165 6 mg BID for the Maintenance Period, 
and they will be managed as described above.

Open-label Extension Period (Week 52 through Week 104)
Subjects who complete per protocol assessments at Week 52 who have an appropriate safety 
profile and who also continue to derive a clinical benefit from IP at that time in the opinion of the 
investigator, are eligible to enter the OLE Period. The OLE Period lasts 52 weeks, from Week 52 
through Week 104. The final study endoscopy should be performed within a window of 7 days 
prior to the Week 104 visit.
Post-treatment Follow-up Period:
Subjects who permanently discontinue IP prior to Week 52 will enter a 28-day Post-treatment 
Follow-up Period. Subjects will be instructed to report to the investigative site any adverse events 
(AEs) or serious adverse events (SAEs) experienced during this 28-day period.

Endoscopy (ileocolonoscopy)
X
After bowel cleansing, video ileocolonoscopic examination must be performed within Day -28 and Day -1 
of the Screening Period and should be scheduled as close as possible to the Week 0 visit. The Week 0 visit 
should occur within 14 days of the screening endoscopy. Best practice is to complete the other screening 
investigations first and check results to ensure that a subject continues to be potentially eligible for the 
study prior to commencing bowel preparation for the endoscopy. At this examination, endoscopic 
collection of ileal and/or colonic tissue biopsies will be performed.
SES-CD
X
The SES-CD score is centrally read from the screening endoscopy and the central read must be reviewed 
to confirm eligibility prior to randomization. Local reads will not be used for study eligibility. Study sites 
should consider turnaround time for central reads to ensure results are obtained before the Week 0 visit. 
Results from central endoscopy review are final.
Definitions of SES-CD are provided in APPENDIX 12.

INTRODUCTION
3.1
Background
Tyrosine kinase 2 (TYK2) is a protein involved in interleukin (IL)-12, IL-23 and Type I interferon 
(IFN) signaling, and it is required for the activation of downstream signaling pathways. TYK2 is 
a widely expressed, non-receptor tyrosine kinase that catalyzes the phosphorylation of signal 
transducer and activator of transcription (STAT) proteins downstream of the receptors for the p40-
containing cytokines IL-12 and IL-23, as well as the Type I IFN receptor. This results in the 
activation of STAT-dependent transcription and functional responses specific for these 
cytokines.1,2,3 TYK2-dependent cytokines (eg, IL-12, IL-23 and Type I IFNs) are distinct from 
those dependent on closely related Janus kinase (JAK) family members JAK1, JAK3 (eg, IL-2, 
IL-15, IL-7, IL-6) or JAK2 (eg, erythropoietin, thrombopoietin, and granulocyte-monocyte 
colony-stimulating factor). Consequently, a TYK2 inhibitor is expected to have a highly 
differentiated profile from inhibitors of other JAK family kinases. TYK2-dependent pathways and 
the cytokine networks they modulate (eg, IL-23, IL-17, IFNα) have been implicated in the 
pathophysiology of multiple immune-mediated diseases, including Crohn’s disease (CD), 
ulcerative colitis, psoriasis, psoriatic arthritis, systemic lupus erythematosus (SLE) and 
spondyloarthritides.
BMS-986165 is an orally administered selective TYK2 inhibitor. A comprehensive in vitro and 
in vivo characterization of BMS-986165 has been established and supports the development of 
this compound in humans. Inhibition of TYK2 is expected to provide therapeutic benefit for 
patients with CD for multiple reasons: 1) IL-12 and IL-23 have been implicated in pathogenesis 
of CD;4 2) Biologic agents targeting IL-23p19 and IL-12/23p40 cytokines have been shown to be 
efficacious in CD, and ustekinumab targeting IL-12/23p40 has been approved for the treatment of 
CD; and 3) BMS-986165 has been shown to be efficacious in psoriasis, an IL-23-mediated disease, 
in a recent Phase 2 study.5
IM011023 is a Phase 2 randomized, double-blind placebo-controlled study designed to assess the 
safety and efficacy of BMS-986165 compared to placebo in subjects with moderately to severely 
active CD. Approximately 240 subjects will be randomized in this study. After a 28-day Screening 
Period, eligible subjects will be randomized in a 3:3:2 ratio to one of three study arms: 
(i) BMS-986165 6 mg twice daily (BID) by mouth (PO); n≈90, (ii) BMS-986165 3 mg BID PO; 
n≈90, or (iii) matched placebo; n≈60. 
 
 
 
 
The Induction Period lasts from Week 0 through 
Week 12. The primary outcome for the study will be assessed at Week 12 (Day 85).
The Maintenance Period lasts from Week 12 through Week 52. This study has a treat-through 
study design. Subjects who achieve clinical response at Week 12 (Day 85), with an appropriate 
safety profile, are eligible to continue into the Maintenance Period, during which they will continue 
to receive the same blinded study treatment regimen (BMS-986165 6 mg BID or 3 mg BID or

for subjects who do not achieve a clinical response at Week 12, and for subjects in the treat-through 
study arms who have a loss of response (LOR) to blinded treatment between Week 13 and 
Week 52. The Open-label Extension (OLE) Period lasts from Week 52 through Week 104 and is 
available to subjects who complete per protocol assessments at Week 52 and who continue to 
derive clinical benefit from investigational product (IP) at that time.
 
3.1.1
Nonclinical Toxicology
The projected systemic exposure multiples presented in this section are expressed relative to the 
highest anticipated mean steady-state systemic exposure in human following oral dosing at 
6 mg BID (mean AUC[0-24h] = 857 ng•h/mL) and were calculated as animal sex-combined mean 
AUC ÷ human sex-combined mean AUC at the no-observed-adverse-effect level (NOAEL) or 
level associated with adverse findings in the pivotal toxicology studies.
In single-dose oral toxicity studies, BMS-986165 was well tolerated up to the highest administered 
doses of 75, 100, and 30 mg/kg in rats, dogs, and monkeys, respectively. 
In repeat-dose oral toxicity studies in rats, BMS-986165 was tolerated at all doses (5, 15, or 
75 mg/kg/day for 1 month; 2, 5, or 15 mg/kg/day for 3 months; and 5, 15, or 50 mg/kg/day for 
6 months). All doses were associated with on-target pharmacodynamic (PD) effects. Systemic 
exposures to BMS-986165 increased approximately dose proportionally, with no substantial sex 
differences, accumulation, or loss of exposure in all studies. In the 6-month rat toxicity study with 
2-month postdose recovery period, BMS-986165 was tolerated by rats for 6 months at oral doses 
≤50 mg/kg/day (mean sex-combined AUC[0-24h] ≤117 μg•h/mL; ≤137-fold AUC multiple). 
Consistent with BMS-986165-mediated pharmacologic immunomodulation, the primary findings 
at ≥5 mg/kg/day were decreased peripheral blood lymphocyte counts, lymphoid cellularity in 
lymph nodes and spleen, and/or suppression of T-cell dependent antibody response (TDAR) to 
keyhole limpet hemocyanin (KLH) immunogen. No BMS-986165-related infections were noted. 
Additional BMS-986165-related findings considered adverse at ≥15 mg/kg/day (mean 
sex-combined AUC[0-24h] ≥19.7 μg•h/mL; ≥ 23-fold AUC multiple) included decreased mean 
body weights and body-weight gains, decreased red blood cell (RBC) mass parameters, 
reticulocytes, platelets, and bone marrow cellularity. All BMS-986165-related changes were 
reversible except for the decreased food consumption and body weights, decreased spleen weights, 
and nonadverse increased incidence of macrophage aggregation in the lung. In conclusion, based 
on the absence of adverse findings, the NOAEL was considered to be 5 mg/kg/day (mean 
sex-combined AUC[0-24h] 4.31 μg•h/mL; 5-fold AUC multiple).
In repeat-dose (≤ 3 months) oral toxicity studies in monkeys, BMS-986165 was well tolerated at 
all doses (0.5, 1.5, or 5 mg/kg/day for 1 month; 0.75, 1.5, or 5 mg/kg/day for 3 months). All doses 
were associated with on-target PD effects. Exposures to BMS-986165 increased approximately 
dose proportionally, with no substantial sex differences, loss of exposure or accumulation noted.
There were no BMS-986165-related mortalities at any dose during any monkey toxicity studies.

BMS-986165
TYK2 Inhibitor
In the 9-month monkey toxicity study (doses of 0, 1, 3, or 10 mg/kg/day; the 10-mg/kg dose was 
changed to 5 mg/kg due to observed toxicity) with 2-month postdose recovery period, the principal 
BMS-986165-related findings at all doses included generally dose-dependent skin changes, which 
were likely infectious in etiology, and secondary to BMS-986165-mediated pharmacologic 
immunomodulation. The various skin changes (swollen, dry, lesion, flaking, papule, red, white, 
scab) were located throughout the body, and could be seen as early as Week 1 in some monkeys. 
The skin changes were noted at necropsy as abrasions, discoloration, foci, nodule, scab, scale, 
and/or thick, and correlated with microscopic findings in the epidermis (hyperkeratosis, erosion, 
and/or crusts) and/or dermis (mixed cell infiltrates and/or subacute inflammation). Although no 
definitive microbial pathogens were confirmed as the causative agents, the skin changes were 
considered likely infectious in etiology, as they improved following antibiotic and antiseptic 
treatments, and were present in the context of BMS-986165-mediated immunomodulation. 
Additional findings at all doses included transient slight to severe liquid feces, which improved 
clinically with veterinary treatments, dose-dependent decreased RBC mass parameters, and 
suppression 
of 
TDAR 
to 
KLH, 
and 
at 
≥3 mg/kg/day 
(mean 
sex-combined 
AUC[0-24h] ≥15.4 μg•h/mL; ≥ 18-fold AUC multiple) decreased activity, hunched posture, pale 
gums, and increased body temperature, with decreased platelets and occult blood in urine at 
10 followed by 5 mg/kg/day (mean sex-combined AUC[0-24h] 30.7 μg•h/mL; 36-fold AUC 
multiple). Following the 2-month recovery period, all BMS-986165-related findings were partially 
or fully reversible. The NOAEL was not identified due to the presence of adverse skin findings at 
doses ≥ 1 mg/kg/day (mean sex-combined AUC[0-24h] ≥3.38 μg•h/mL; ≥ 4-fold AUC multiple). 
Although the NOAEL was not determined in this study, the skin findings did not result in any 
unscheduled euthanasia or preterminal deaths, were clinically monitorable, manageable with 
veterinary treatments, and trended towards reversibility during the 2-month post-dose recovery.
BMS-986165 was not genotoxic or phototoxic. There was no evidence of teratogenicity or effects 
on development up to the highest administered doses of 75 mg/kg/day in the rat (AUC[0-24h] 
126 μg•h/mL; 147-fold AUC multiple) or 10 mg/kg/day in the rabbit (AUC[0-24h] 43.2 μg•h/mL; 
50-fold AUC multiple). BMS-986165 had no effects on male rat reproductive parameters (mating, 
fertility, and sperm morphology), or early embryonic development of the litters sired by treated 
males up to 50 mg/kg/day (AUC[0-24h] 117 μg•h/mL; 137-fold AUC multiple). In a female rat 
fertility study (preliminary results), there were no BMS-986165-related effects on mating and 
fertility parameters up to 50 mg/kg/day, and the maternal and reproductive NOAEL were 
considered to be 50 mg/kg/day (AUC[0-24h] 81.1 μg•h/mL; 95-fold AUC multiple).
In summary, the totality of the toxicity assessments demonstrates that BMS-986165, at doses 
associated with robust PD effects, has a favorable dose-related safety profile in both rodents and 
nonrodents, toxicological findings that are either fully reversible or trending towards recovery, and 
are clinically monitorable and manageable.

Study Rationale
3.2.1
Scientific Rationale for Study Design
IM011023 is a Phase 2 randomized, double-blind, placebo-controlled clinical study designed to 
assess the safety and efficacy of BMS-986165 compared to placebo in subjects with moderately 
to severely active CD. 
Approximately 240 subjects will be randomized in this study. After a 28-day Screening Period, 
eligible subjects will be randomized in a 3:3:2 ratio to one of three study arms: (i) BMS-986165 
6 mg BID by mouth (PO); n≈90, (ii) BMS-986165 3 mg BID PO; n≈90, or (iii) matched placebo; 
n≈60. 
 
 
 
This study has a 12-week Induction Period, a 40-week Maintenance Period, and a 52-week OLE 
Period leading to a total of up to 104 weeks of exposure to IP. The primary efficacy assessment 
occurs at Week 12. The co-primary endpoints are defined as achieving clinical remission (defined 
as Crohn’s Disease Activity Index [CDAI] of < 150) and achieving endoscopic response 
(≥50% improvement from baseline in the Simple Endoscopic Score for Crohn’s Disease 
[SES-CD]), on a population basis, at Week 12. This study is powered for the primary endpoint at 
Week 12.
This study has a treat-through design in order to explore sustained clinical benefit and safety in the 
Maintenance Period. Subjects who achieve clinical response (a reduction from baseline in the 
CDAI score of ≥100 points or a total CDAI score < 150) at Week 12 (Day 85), are eligible to enter 
the Maintenance Period and to continue on the same, double-blind treatment regimen that they 
received in the Induction Period, for up to an additional 40 weeks, up to Week 52. Subjects with 
LOR (an increase in the CDAI score of ≥100 points compared to Week 12, and a total CDAI score 
of ≥220 points, at any time from Week 13 through Week 52) in the Maintenance Period are 
eligible to enter an open-label BMS-986165 6 mg BID PO arm through Week 52.
Subjects who do not achieve clinical response at Week 12 and who have an appropriate safety 
profile are eligible to enter an open-label BMS-986165 6 mg BID PO arm, in which clinical 
response is again assessed at Week 26 (compared to Week 0). This study arm is designed to explore 
the potential benefit of ongoing treatment with BMS-986165 in subjects who do not achieve 
clinical response by that time. This may include subjects who received either BMS-986165 or 
placebo in the Induction Period. Subjects who achieve clinical response at Week 26 (compared to 
Week 0) may continue in this arm through Week 52. Subjects who do not achieve clinical response 
at Week 26 (compared to Week 0) will be considered treatment failures and must permanently 
discontinue IP and enter the Post-treatment Follow-up Period.

Subjects who complete per protocol assessments at Week 52 and who continue to derive clinical 
benefit from IP, in the opinion of the investigator, are eligible to enter the OLE Period, which lasts 
up to Week 104. This period explores safety and efficacy of BMS-986165 beyond Week 52.
Throughout the study, subjects who permanently discontinue IP prior to Week 104 must enter the 
Post-treatment Follow-up Period.
Taken together, these data provide a scientific rationale for studying BMS-986165 in CD.

Clinical disease activity is assessed in this study using the CDAI.10 CDAI is a composite 
instrument that includes patient-reported abdominal pain (AP), stool frequency (SF), general 
well-being, presence of complications of CD, hematocrit, body weight, presence of a CD-related 
abdominal mass, and the use of antidiarrheal medication. CDAI has been widely used in 
registrational clinical trial programs, but does have certain limitations eg, (i) the AP and SF 
components are weighted, (ii) the CDAI incorporates items that are not patient-reported outcomes 
(PROs), (iii) the CDAI does not include an assessment of mucosal inflammation, and (iv) the 
CDAI does not correlate well with endoscopic findings.10,11 In order to address these limitations, 
a PRO2 (patient-reported outcome based on the stool frequency and abdominal pain components 
of the CDAI) instrument that includes unweighted AP and SF will be evaluated during the study,
and mucosal inflammation will also be assessed by endoscopy 
.12 Thus, in addition 
to classical definitions of CDAI response and remission, this study will also examine PRO2-based 
endpoints, endoscopic response and remission,

Benefit/Risk Assessment
 
 
 
 
 
 
 
These data suggest that subjects with CD are likely to derive clinical benefit 
after treatment with BMS-986165.
As discussed in Section 3.1, and detailed in the Investigator’s Brochure, the safety and tolerability 
of BMS-986165 at multiple doses, including 6 mg BID, have been investigated in normal healthy 
volunteer studies, Phase 2 and Phase 3 clinical studies in psoriasis, and a Phase 2 clinical study in 
psoriatic arthritis. Overall, in the Phase 1 studies, BMS-986165 was generally well tolerated. In 
the Phase 2 study in psoriasis (IM011011), BMS-986165 was generally safe and well tolerated. In 
two Phase 3 clinical studies in psoriasis (IM011046 and IM011047), BMS-986165 6 mg QD PO 
was superior to placebo and apremilast in achieving the coprimary endpoints of PASI 75 and static 
Physician’s Global Assessment (sPGA) 0/1 responses at Week 16. In a recent Phase 2 clinical 
study in psoriatic arthritis (IM011084), BMS-986165 12 mg QD and 6 mg QD demonstrated 
significantly greater American College of Rheumatology 20 (ACR20) responses at Week 16 
compared with placebo. The IL-23/TH17 axis has been implicated as an important immune 
pathway in the pathogenesis of psoriasis, psoriatic arthritis, and CD. Taken together, these data 
indicate an overall favorable benefit-risk assessment for evaluating BMS-986165 as an oral 
treatment for patients with CD.

The proposed dosing regimens reflect implementation of appropriate safety margins and are within 
the range of doses tested in the FIH study and within exposure margins based on comparisons of 
systemic exposure and body surface area with toxicology findings.
The effects of TYK2 inhibition by BMS-986165 have been documented in pharmacology studies, 
and the potential for benefit in CD is supported through in vivo studies showing BMS-986165 is 
highly efficacious in murine models for lupus, colitis, and psoriasis. In all models, robust efficacy 
was observed at doses providing continuous coverage of the mouse whole blood IC50 values over 
the dosing interval. 
BMS-986165 was safe when investigated in clinical study IM011002 with healthy subjects at 
single doses up to 40 mg and multiple doses of 24 mg/day (12 mg BID) for 14 days. However, 
BMS-986165 did elicit dose-dependent, mild-to-moderate acne-like skin lesions particularly after 
multiple doses of 24 mg/day (12 mg BID). Importantly, all the skin-related AEs were mild or 
moderate, with no signs or symptoms of circulatory impairment or respiratory distress in these 
subjects; required topical treatment in only a few cases, responded quickly and appropriately when 
treatment was required, and rarely required discontinuation of study drug. Due to these findings, 
the highest proposed dose for the Phase 2 study IM011023 in subjects with CD will be 6 mg BID. 
In case of the occurrence of skin-related events, subjects may receive treatment as per standard 
practice according to investigator’s discretion and followed until resolution. 
 
 
 At the maximum concentrations expected in this study (in portal vein or systemic 
circulation, as appropriate), the potential for DDIs involving CYP450 enzymes and most 
transporters is low. BMS-986165 has low turnover in in vitro metabolism studies, and a number 
of enzymes are involved in the metabolism of the fraction metabolized. Additionally, 
BMS-986165 is not an inhibitor or inducer of CYP450 enzymes at the expected clinical 
concentrations. Therefore, the potential for DDIs resulting from CYP450 inhibition or induction 
is low. BMS-986165 is a breast cancer resistance protein (BCRP) inhibitor with an in vitro 
IC50 = 0.31 μM. However, due to overlapping substrate specificity between BCRP and other 
transporters not affected by BMS-986165 at the expected concentrations, the impact of 
BMS-986165 on the exposures of potential co-medications that are BCRP substrates, such as 
rosuvastatin, was also expected to be low. Based on data from IM011015 DDI study with 
rosuvastatin, co-administration of 12 mg QD BMS-986165 and 10 mg rosuvastatin had no impact 
on the exposure of rosuvastatin. Data from a study evaluating the impact of BMS-986165 in 
women taking oral contraceptives found no impact on exposure of ethinyl estradiol or 
norethindrone. 
The reproductive toxicology studies for BMS-986165 are complete and detailed in the IB. Briefly, 
BMS-986165 is not genotoxic. BMS-986165 was neither teratogenic nor fetotoxic up to the 
highest evaluated dose of 50 mg/kg/day, and there was no evidence of teratogenicity or effects on 
development in reproductive and developmental toxicity studies in rats and/or rabbits. These 
findings support the contraception requirements for this study.

In addition, a completed thorough QTc study has excluded a clinically meaningful effect on QT 
interval at doses of up to 36 mg (a supratherapeutic dose).
Taken together, these data suggest that BMS-986165 may be beneficial, safe and well tolerated in 
patients with active CD. In addition, there is no evidence for clinically significant DDIs at the 
concentrations expected in this study, or clinically meaningful effects on electrocardiogram (ECG) 
parameters.  The reproductive risk potential has not been comprehensively evaluated in humans.
BMS-986165 is an immunomodulatory IP and a potential immunosuppressant. 
 
 
 
 
 
 
 
 
The global coronavirus disease 2019 (COVID-19) pandemic has been identified as a potential risk 
to clinical study subjects in general, and it may particularly affect individuals with underlying 
chronic diseases. The risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 
infection in subjects taking BMS-986165 is unknown. The individual benefit-risk considerations 
regarding COVID-19 infection remains the responsibility of the investigator. In order to reduce
the risk of asymptomatic SARS-CoV-2 at baseline, subjects will be tested for SARS-CoV-2 during 
the screening period, as close as possible prior to randomization (refer to Section 9.10). Testing 
for SARS-CoV-2 to inform decisions on subject care during the study, should follow local standard 
of care and clinical practice. Potential subjects with recent COVID-19 infection will be excluded 
until their symptoms have completely resolved for 30 days prior to receiving first dose of IP. The 
protocol provides guidance to investigators on temporary discontinuation of IP in the case of 
suspected or proven COVID-19 infection. The protocol also provides guidance on restarting IP 
following recovery from a COVID-19 infection, which must be confirmed by a negative diagnostic 
test for SARS-CoV-2 (Section 8.2.1).
Each study visit will include a clinical assessment for signs and/or symptoms of intercurrent 
illness, including COVID-19 and other infections. Subjects will also be encouraged to contact the 
investigator if they develop an intercurrent illness between study visits. The study captures 
treatment-emergent AEs (occurring after randomization). In order to facilitate enhanced reporting 
of SARS-CoV-2–related AEs that occur during the study, these AEs (and serious adverse events 
[SAEs]) must be reported from the time of consent (Section 9.3.2).
 
 Nevertheless, 
BMS-986165 is a potential immunosuppressant, and in line with standard practice for 
immunosuppressant IPs, this study has been designed with eligibility criteria that minimize the 
risk that a subject with malignancy will be enrolled. Subjects with a clinical picture that is

suspicious for malignancy are excluded from participation. Subjects are not allowed to enter the 
study with unresected colonic adenomas or unresected colonic dysplasia. Standard-of-care 
screening for colorectal neoplasia and surveillance for dysplasia can be incorporated into the 
baseline endoscopy in this study, and into subsequent annual study endoscopies.
Subjects in IBD clinical studies may experience an increase in disease activity (ie, disease 
exacerbation or a “flare”) during their participation. Investigator recognition of treatment futility 
or a requirement for efficacious treatment outside of the study is important in the management of 
CD patients. Subjects may remain on permitted background standard of care therapy regardless of 
whether they are randomized to one of the active treatment or placebo arms. At the investigator’s 
discretion, rescue therapy can be initiated, or dosing of study medication can be discontinued at 
any time during the study. The protocol provides guidance to investigators on the level of disease 
activity that constitutes a LOR to IP in the maintenance period. The protocol also requires that 
subjects who do not achieve a clinical response at Week 12 and at Week 26 must permanently 
discontinue IP and enter the Post-treatment Follow-up Period. These design elements are intended 
to assist investigators in the recognition and management of treatment failure within the study. 
In addition to a comprehensive monitoring of safety with oversight by the investigators, medical 
monitors from both Bristol-Myers Squibb (BMS) and the partner organization, Pharmaceutical 
Research Associates (PRA), and the BMS Safety Physician, the safety of subjects will also be 
monitored by an independent Data Monitoring Committee (DMC). 
Taken together, the study design, including eligibility criteria, clinical assessments at study visits, 
study investigations such as safety bloods and endoscopies, and guidance for investigators on the 
recognition and/or management of AEs (including potential infections and disease exacerbation) 
mitigate expected risks and facilitate the detection and management of reasonably anticipated AEs 
in this study.
In summary, existing preclinical data and clinical experience in healthy subjects in combination 
with the design and doses selected for the proposed Phase 2 study indicate an overall favorable 
benefit-risk assessment of investigating BMS-986165 as an oral treatment for subjects with CD. 
Additional detailed information on the known and expected benefits and risks and reasonably 
anticipated AEs of BMS-986165 is provided in the IB.

Subjects should receive and be trained on an electronic patient diary at the screening visit. Subjects 
are expected to complete the electronic diary on a daily basis through the Screening Period, and 
then throughout their ongoing participation in the study.  
Endoscopic (ileocolonoscopy) evaluations and collection of ileal and/or colonic tissue biopsies 
will be performed during the Screening Period, at the end of the Induction Period (Week 12), and 
at the end of the Maintenance Period (Week 52) and OLE Period (Week 104). Ileocolonoscopy 
will also be performed at Early Termination (ET) visits that occur at least 4 weeks after the most 
recent per protocol endoscopy. These are required for ET visits occurring between Week 4 and 
Week 12 (Induction Period), and optional but recommended for ET visits occurring between 
Weeks 16 and Week 52 (Maintenance Period), and Weeks 56 and 104 (OLE Period). Endoscopic 
procedures will be video-recorded and scored for disease activity by a blinded central reader. 
 
 
 
 
 
 
Physical examinations, vital sign measurements, 12-lead ECG, and clinical laboratory evaluations 
will be performed at selected times throughout the dosing interval, as indicated in the Schedule of 
Activities (Section 2). Subjects will be closely monitored for AEs throughout the study. 
 
(Table 2, Table 3, and Table 4). 
A DMC will be instituted to monitor subject safety during the study (Section 5.1.5).
The study design schematic is presented in Figure 1 and Figure 2. 
Subjects who were randomized when Protocol v1.0 (27-Mar-2018) or Protocol v2.0 
(24-May-2018) were in effect will continue on their currently assigned double-blind study 
treatment. These subjects will complete all study procedures and assessments outlined in the 
current version of the protocol.

a Subjects who achieve clinical response at Week 12 can enter the OL “loss of response” arm at any time from 
Week 13 through Week 52. Loss of response is defined as an increase in the CDAI score of ≥ 100 points compared 
to Week 12, and a total CDAI score of ≥ 220.
NOTE: This study has a treat-through design. At Week 12, subjects who achieve clinical response (defined as a 
reduction from baseline in the CDAI score of ≥100 points or a total CDAI score < 150) are eligible to continue to the 
Maintenance Period, where they will continue to receive the double-blind treatment regimen that they received in the 
Induction Period. Subjects who have loss of response in these arms may be eligible to enter the loss of response arm, 
where they will receive open-label BMS-986165 6 mg BID PO through Week 52. Subjects who do not achieve clinical 
response at Week 12 and who have an appropriate safety profile are eligible to enter an open-label treatment arm, in 
which they will receive open-label BMS-986165 6 mg BID PO during the Maintenance Period. Subjects in this arm 
must have clinical response assessed again at Week 26 (compared to Week 0). Subjects in this arm who do not achieve
clinical response at Week 26 (compared to Week 0) will be considered treatment failures and must permanently 
discontinue IP and enter the Post-treatment Follow-up Period. Subjects in this arm who do achieve clinical response 
at Week 26 may continue IP through Week 52.

Screening Period
Once subjects sign the ICF, they are considered “enrolled” in the study and they enter the 
Screening Period. During the Screening Period, subjects will complete the study procedures 
outlined in the Schedule of Activities to determine if they meet eligibility criteria (Section 6). 
In order to be eligible for the study, a subject must meet minimum disease activity criteria outlined 
in the inclusion criteria (Section 6.1), assessed by CDAI, PRO2, and SES-CD.
Subjects are expected to complete a daily diary throughout the Screening Period. AP and SF data 
recorded in the daily diary contributes to disease activity assessment during screening and 
throughout the study. The minimum daily diary requirements for CDAI/PRO2 calculations are 
outlined in Section 9.1. In order to ensure that a subject can be successfully randomized, sites 
should consider periodically confirming that subjects are successfully entering and uploading daily 
diary data (see Section 9.1, APPENDIX 10, and
.
Screening endoscopy is performed in order to determine if a subject has active intestinal 
inflammation (assessed by centrally read SES-CD), 
 
 For screening and throughout the study, endoscopy should 
ideally be performed on a different day than the office visit, in order to avoid potentially 
confounding effects of bowel preparation, the endoscopy procedure, or sedation on clinical 
assessments, especially patient-reported outcome data.
In order to avoid unnecessary endoscopies, best practice is to complete other screening 
investigations first, and to check the results of those investigations for abnormalities before a 
subject begins bowel preparation for endoscopy. This ensures that a subject continues to be

potentially eligible for the study before they commence bowel preparation. Subjects should be 
randomized within 14 calendar days of the endoscopy.
Consequently, when operationalizing the Screening Period, please consider the following:
i.
Study procedures cannot be performed before the subject signs the ICF. Once the ICF is 
signed at the screening visit, sites should consider obtaining a medical history, vital signs 
and physical examination, and other per protocol screening visit investigations such as 
blood tests, ECG, and chest x-ray (if required), giving the subject the electronic study diary 
and training on the diary, and also scheduling the screening ileocolonoscopy and Week 0 
visit. Sites should consider the turnaround time for the centrally read endoscopy result 
when scheduling the ileocolonoscopy and Week 0 visits.
ii.
The study diary requirements for the calculation of CDAI/PRO2 are outlined in 
Section 9.1. In order to ensure that a CDAI score can be determined, sites should consider 
periodically confirming that subjects are successfully entering and uploading daily diary 
data.
iii.
Sites should check the results of screening investigations to confirm that a subject remains 
potentially eligible for inclusion before they commence bowel preparation for the screening 
ileocolonoscopy.
iv.
Once the screening ileocolonoscopy is performed, subjects should be randomized within 
14 days. 
In order to be eligible for randomization, subjects must have had an inadequate response, LOR, or 
intolerance to a standard treatment course of 1 or more of the following medications, as outlined 
in Inclusion Criterion 2)g):
i.
Oral 5-ASAs, oral corticosteroids, intravenous (IV) corticosteroids, or immunomodulators, 
and/or
ii.
Infliximab, adalimumab, certolizumab pegol, vedolizumab, ustekinumab, or natalizumab.
 
 The prior medication failure or intolerance used to qualify a subject 
for Inclusion Criterion 2)g) must be recorded in source documents. 
The medications outlined in APPENDIX 7 are subject to a washout period prior to the day of 
randomization (Week 0). These medications include immunomodulators (eg, methotrexate 
[MTX], 5-azathioprine [AZA], 6-mercaptopurine [6-MP]) and biologic medications (eg, 
infliximab, adalimumab, certolizumab pegol, vedolizumab, natalizumab, and ustekinumab). In 
order to be eligible for randomization, subjects taking the medications listed in APPENDIX 7  must 
discontinue those medications prior to randomization and comply with washout periods listed in 
APPENDIX 7.

Some subjects will require adequate washout of biologics in order to be eligible for randomization. 
Therapeutic drug monitoring (TDM) assays that test for drug levels of these biologic medications 
are commercially available in routine clinical practice, and also available as an optional test during 
the Screening Period. The washout period for the following biologics can be waived for subjects 
who have an undetectable drug level on a TDM assay, performed either in routine clinical practice 
or during the Screening Period: (i) infliximab, (ii) adalimumab, (iii) certolizumab pegol, (iv) 
vedolizumab (if received > 14 weeks of vedolizumab therapy), or (v) ustekinumab (if received 
> 12 weeks of ustekinumab therapy). If a TDM assay is used to waive the washout period for any 
of the 5 biologics listed above, the result of the TDM assay must be available in source documents, 
and the subject cannot receive another dose of that biologic prior to randomization.
Corticosteroids (prednisone ≤20 mg QD PO or equivalent 
 or ileal-release 
budesonide ≤9 mg QD PO [eg, Entocort® EC]), 5-ASAs, probiotics, and CD-related antibiotics 
are allowed, subject to dose stabilization rules outlined in Section 6.3.
Selected subjects with complicated CD may be eligible to participate in this study. Subjects with 
perianal fistulizing disease are eligible to participate in the study, provided they meet the other 
inclusion/exclusion criteria, eg, perianal abscess should be carefully excluded during the Screening 
Period. In addition, certain subjects with asymptomatic stenosing disease may be eligible to 
participate in this study. However, subjects whose symptoms are primarily attributable to 
CD-related strictures are excluded, as obstructive symptoms or overflow diarrhea caused by a 
CD-related stricture are unlikely to respond to anti-inflammatory treatment and these may 
confound efficacy assessment. Malignancy should be carefully excluded in subjects with 
CD-related colonic strictures. 
5.1.2
Induction Period
On Day 1 of the Induction Period, subjects who have completed the screening procedures and met 
the inclusion/exclusion criteria will be randomized in a 3:3:2 ratio to receive oral BMS-986165 
6 mg BID or 3 mg BID or placebo BID, respectively, 
Video ileocolonoscopic examination and collection of ileal and/or colonic tissue biopsies should 
be performed within a window of 7 days prior to the Week 12 visit. Note: This requirement will

also apply to subjects who terminate early and have received study treatment for at least 4 weeks. 
The study diary requirements for the calculation of CDAI/PRO2 are outlined in Section 9.1.
Clinical response will be assessed at Week 12 (Section 5.1.3) to determine whether subjects will 
continue on the initially assigned double-blind dose or be offered the opportunity to switch to 
open-label BMS-986165 6 mg BID for the Maintenance Period. Subjects who were randomized 
prior to the implementation of Protocol v3.0 who have not yet reached Week 12 will likewise be 
offered the opportunity to switch to open-label BMS-986165 6 mg BID for the Maintenance 
Period, if they do not achieve a clinical response at Week 12.
If, in the opinion of the investigator, a subject requires rescue therapy for CD during the Induction 
Period, the subject must permanently discontinue study treatment, complete an ET Visit and enter 
the Post-treatment Follow-up Period. Examples of rescue therapies that are prohibited in this study 
include prednisone > 20 mg QD PO (or equivalent), intramuscular (IM) or IV corticosteroids, and 
biologic therapies that are approved for the treatment of CD in at least 1 country (
and Section 7.7.1). Endoscopy is required at the ET Visit for subjects who permanently discontinue 
study medication between Weeks 4 and 12. Discontinuation criteria are further detailed in 
Section 8.
5.1.3
Maintenance Period
There will be a seamless transition between the Induction Period and Maintenance Period.
The Maintenance Period will last up to 40 weeks (52 weeks total).
Subjects who require prohibited rescue treatment for CD (see 
 Section 7.7.1) 
during the Maintenance Period must permanently discontinue study treatment, complete an 
ET Visit, and enter the Post-treatment Follow-up Period. An exit endoscopy is recommended for 
all subjects who undergo an ET Visit between Weeks 16 and 52. This is not required for ET Visits 
within 4 weeks of the Week 12 endoscopy.
5.1.3.1
Week 12 (Day 85), End of Induction Period 
Subjects who achieve a protocol-defined clinical response at Week 12 are eligible to enter the 
Maintenance Period and continue to receive the same blinded study regimen that they received in 
the Induction Period. Blinded study treatment will continue until the subject completes Week 52, 
experiences LOR (Section 5.1.3.3), and switches to open-label treatment, or discontinues from the 
study. 
At Week 12, subjects who do not achieve a clinical response will be offered the opportunity to 
switch to open-label BMS-986165 treatment at the highest dose (6 mg BID PO), regardless of the 
initial treatment regimen received during the Induction Period. Subjects who were randomized 
prior to the implementation of Protocol v3.0 who have not yet reached Week 12 will likewise be 
offered the opportunity to switch to open-label BMS-986165 6 mg BID for the Maintenance 
Period, if they had not achieved a clinical response at Week 12.
Study treatment may be adjusted by the Sponsor should any emerging safety/tolerability issues be 
identified by the investigators, Sponsor, and/or DMC. Entrance of a subject to the Maintenance

Period or to an open-label study arm is conditional on an appropriate safety profile. Any safety 
concerns should be discussed with the medical monitor.
5.1.3.2
Week 26 (Day 183) 
Subjects who do not achieve a clinical response at Week 12 and who have an appropriate safety 
profile are eligible to switch to open-label BMS-986165 treatment at the highest dose (6 mg BID), 
regardless of the initial treatment regimen received during the Induction Period.
Subjects who do not achieve protocol-defined clinical response at Week 12 and are switched to 
the open-label BMS-986165 6 mg BID study arm, as well as those who are currently receiving 
open-label BMS-986165 12 mg QD prior to implementation of Protocol v3.0, must be assessed 
for clinical response at Week 26. If clinical response at Week 26 (compared to Week 0) is 
achieved, and subjects have an appropriate safety profile, these subjects are eligible to continue on 
the open-label treatment for the remaining duration of the Maintenance Period.
Subjects in the open-label study arm who do not achieve clinical response at Week 26 (compared 
to Week 0) will be considered treatment failures and must permanently discontinue IP and enter
the Post-treatment Follow-up Period. Note: These subjects may also be discontinued at any time 
before Week 26 based on the clinical judgment of the investigator.
5.1.3.3
Week 12 Responders: Loss of Response in the Maintenance Period
Subjects who achieve clinical response at Week 12 and continue on blinded study treatment will 
be judged to have LOR if they experience a worsening of clinical disease activity between 
Weeks 13 and 52, as defined below:
•
≥ 100 point increase in CDAI score, compared with CDAI score at Week 12, and
•
Total CDAI score ≥220
These subjects are eligible to enter the open-label LOR arm, during which they will receive 
BMS-986165 6 mg BID PO through Week 52.
5.1.3.4
Week 12 Non-responders: Loss of Response after Week 26 in the Open-
label Arm
Subjects who do not achieve clinical response at Week 12 and who have an appropriate safety 
profile are eligible to enter the open-label BMS-986165 6 mg BID PO arm. Subjects in that arm 
who achieve clinical response at Week 26 will be judged to have LOR if they experience a 
worsening of clinical disease activity between Weeks 27 and 52, defined as:
•
≥ 100 point increase in CDAI score compared to Week 26, and
•
Total CDAI score ≥ 220
A subject in this open-label treatment arm with LOR after Week 26 will be considered a treatment 
failure, must permanently discontinue study treatment, and must complete the appropriate per 
protocol procedures.

Open-label Extension Period
Subjects who continue to derive a clinical benefit from IP at Week 52, as judged by the 
investigator, are eligible to enter the OLE Period. The OLE Period will last 52 weeks, to Week 104. 
Study visits in this period occur every 4 weeks for the first 3 months, then approximately every 
3 months afterwards, to Week 104. The final ileocolonoscopy will occur within a window of 
7 days prior to the Week 104 visit. The study diary requirements for the calculation of CDAI/PRO2 
are outlined in Section 9.1.
Subjects who require prohibited rescue treatment for CD (see 
and Section 7.7.1) 
during the OLE Period must permanently discontinue study treatment, complete an ET Visit, and 
enter the Post-treatment Follow-up Period. An exit endoscopy is recommended for all subjects 
who undergo an ET Visit between Week 56 and Week 104. This is not required for ET Visits 
within 4 weeks of the Week 52 endoscopy.

Eligibility criteria for this study have been carefully considered to ensure the safety of the study 
subjects and that the results of the study can be used. It is imperative that subjects fully meet all 
eligibility criteria.
6.3
Randomization Criteria
Eligible subjects must meet the following criteria on Day 1 before randomization and the first 
dose: 
1) The subject continues to satisfy all eligibility criteria. 
2) If no previous confirmation of diagnosis is available or if previous diagnosis is not deemed 
conclusive, at time of baseline endoscopy, histology must be performed and read locally to 
confirm diagnosis of CD.
3) Previous therapy must follow the rules outlined below:
a) 5-ASAs must be at stable doses for at least 2 weeks prior to the first dose of study treatment 
on Day 1 of the Induction Period.
b) Probiotics must be at stable doses for at least 2 weeks prior to the first dose of study 
treatment on Day 1 of the Induction Period.
c) CD-related antibiotics (ciprofloxacin, metronidazole, etc.) must be at stable doses for at 
least 2 weeks prior to the first dose of study treatment on Day 1 of the Induction Period.
d) Corticosteroids: 
•
Prednisone ≤ 20 mg QD PO (or equivalent) or ileal-release budesonide ≤ 9 mg QD PO 
(eg, Entocort® EC) must be stable for at least 2 weeks prior to randomization.
•
Use of IV corticosteroid is prohibited within 14 days prior to or during the Screening 
Period.
e) Prior exposure to the immunomodulators 6-MP, AZA, and MTX is permitted, but these 
agents must be discontinued for at least 4 weeks prior to the first dose of study treatment 
on Day 1 of the Induction Period. Treatment with cyclosporine, mycophenolate mofetil, 
leflunomide, tacrolimus, JAK inhibitors, or IFN must be discontinued prior to the first dose 
of study treatment on Day 1 of the Induction Period as described in APPENDIX 7. 
f)
The washout period for biologics is discussed in Section 5.1.1 and APPENDIX 7. The 
washout period for infliximab, adalimumab or certolizumab pegol may be waived for 
subjects with an undetectable drug level on a TDM assay performed in routine clinical 
practice, or in screening. The washout period for subjects who have received vedolizumab 
maintenance therapy for > 14 weeks or ustekinumab therapy for > 12 weeks may similarly 
be waived, if a TDM assay shows undetectable drug levels on a TDM assay.
6.4
Lifestyle Restrictions
No restrictions are required.
Study treatment may be taken without regard to meals. However, subjects are required to fast for 
a minimum of 10 hours before visits on which fasting lipid and fasting glucose samples will be 
drawn (at 2 of these visits [Days 1 and 85],

Screen Failures
Screen failures are defined as subjects who consent to participate in the clinical study but who are 
not subsequently randomized in the study. A minimal set of screen failure information is required 
to ensure transparent reporting of screen failure subjects, 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 SAEs.
The study permits the rescreening of a subject who has been deemed as ineligible (screen failure) 
during the Screening Period (ie, the subject has not been randomized/has not been treated). 
Subjects who were screen-failed due to C. difficile infection must be adequately treated and 
subsequently test negative for C. difficile. The subject must be re-consented (ie, re-signing of the 
ICF), and rescreened (if outside the 28-day Screening Period window). Only 1 re-enrollment per 
subject is permissible. 
6.5.1
Retesting During the Screening Period; Rescreening
For laboratory parameters and/or assessments (Table 1) that initially do not meet eligibility 
requirements, a single retest within the 28-day Screening Period is permitted in an effort to find 
all possible well-qualified subjects, unless otherwise noted. Consultation with the medical monitor 
may be needed to identify whether repeat testing of any particular parameter is clinically relevant. 
The study permits the rescreening (after the end of the initial 4-week Screening Period) of a subject 
who discontinues the study as a pretreatment failure (ie, the subject fails screening or 
randomization and has not been treated) or if they have experienced an infection with C. difficile
and were adequately treated, and subsequently test negative for C. difficile (see APPENDIX 20). 
The subject must be re-consented and will be assigned a new identification number, and a full 
screening visit must be performed again. 
A subject can only be rescreened 1 time (ie, if the subject fails 1 rescreening attempt, no additional 
rescreening is allowed). Duration of existing treatments and required discontinuation periods shall 
be considered relative to the given screening visit and/or randomization. 
Subjects who were previously randomized in IM011023 are not eligible for rescreening, even if 
they did not receive a dose of study treatment.
If subjects test positive for C. difficile (see APPENDIX 20), they can be rescreened 30 days after 
completing a full course of standard treatment for C. difficile colitis and subsequently test negative 
for C. difficile. 
The most current result prior to randomization is the value by which study inclusion will be 
assessed, as it represents the subject’s most current clinical state.

TREATMENT
Study treatment is defined as any investigational treatment, marketed product, placebo, or medical 
device intended to be administered to a study subject according to the study randomization or 
treatment allocation.

Study treatment includes IP/investigational medicinal product (IMP) and consists of placebo and 
BMS-986165. Information about the pharmacology and previous experience with BMS-986165 is 
provided in Section 3.1.1 and Section 3.1.2. 
An IP, also known as IMP in some regions, is defined as 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 non-IPs.
7.1
Treatments Administered
During the Induction Period, subjects will take BMS-986165 6 mg BID or 3 mg BID or 
placebo BID over 12 weeks (Section 5.1.2). For each dose level of BMS-986165 or placebo, 
capsules are taken BID (ie, once in the morning and once in the evening).

Study treatment for subjects with no response or who have lost response, and enter into the 
open-label portion of the study will be supplied with the 3 mg hard gelatin capsules. 
 
 
If a subject forgets a dose, but remembers within 4 hours of the expected dose, the dose should be 
taken. If it is past 4 hours, that dose should be missed, and the next expected dose should be taken 
at the usual time. 
Study treatment will be administered in the Maintenance Period, as described in Section 5.1.3 and 
illustrated in Figure 1.
Clinical Responders at Week 12: Subjects who achieve a clinical response (a reduction from 
baseline in the CDAI score of ≥100 points or a total CDAI score < 150) at Week 12 may be 
eligible to enter the double-blind and placebo-controlled Maintenance Period. During the 
Maintenance Period, subjects will take the same blinded study treatment dose level (BMS-986165 
6 mg BID or 3 mg BID or placebo BID) that was assigned during the Induction Period. Subjects 
who were randomized to the BMS-986165 12 mg QD PO study arm when Protocol v1.0 
(27-Mar-2018) or Protocol v2.0 (24-May-2018) were in effect who have not yet reached Week 12 
will continue to receive blinded BMS-986165 12 mg QD for the Maintenance Period if they 
achieve a clinical response at Week 12.
Clinical Non-Responders at Week 12: Subjects who do not achieve a clinical response at Week 12 
and who have an appropriate safety profile are eligible to switch to the BMS-986165 6 mg BID 
PO in the open-label study arm, regardless of the initial treatment regimen received during the 12-
week Induction Period. Subjects who were randomized prior to when Protocol v1.0 (27-Mar-2018) 
or Protocol v2.0 (24-May-2018) were in effect and are currently receiving open-label BMS-
986165 12 mg QD will continue on that dose until discontinuation.
At Week 26 of the Maintenance Period, the investigator will check if these subjects have achieved 
a clinical response (compared to Week 0). Subjects who achieve a clinical response at Week 26 
(compared to Week 0) will continue on open-label treatment at the highest dose level (6 mg BID), 
or continue 12 mg QD if they were already receiving it. Subjects who do not achieve a clinical 
response at Week 26 (compared to Week 0) will be considered treatment failures and must 
permanently discontinue

Method of Treatment Assignment
At the time of the screening visit, immediately after informed consent is obtained and before any 
study-related procedures are performed, the investigative site will access the interactive response 
technology (IRT) for assignment of the subject identification number. This number will be unique 
across all sites. All enrolled subjects, including those not randomized or dosed, will be assigned 
sequential subject numbers. The subject number may not be used for any other subject. If a 
potential subject is rescreened, they will be given a new identification number. 
Eligible subjects will be centrally randomized using IRT to receive oral treatment during the 
Induction Period with BMS-986165 at 6 mg BID or 3 mg BID or placebo BID, according to a 
computer-generated block randomization scheme and in accordance with stratification criteria. 
Randomization numbers will be assigned prior to dosing (Section 5.1).
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 at study visits as shown in 
Section 2 (Schedule of Activities). 
7.3
Blinding
7.3.1
Maintaining the Blind
Blinded treatment assignments will be managed using IRT. 
All capsules (BMS-986165 3 mg and placebo) have an identical matching placebo capsule in order 
to maintain the blind. 
 Investigative 
site staff, Sponsor and designee personnel, and subjects and their families will remain blinded to 
treatment assignments.
The Sponsor may perform an unblinded interim analysis of study data prior to final data analysis. 
A SAP, which will include a section on interim analysis, will be created to fully detail the activities 
around the interim analysis.

The DMC may review unblinded data summaries and listings, at their request (see Section 5.1.5). 
DMC processes and procedures will be outlined in the DMC Charter.
Designated staff of Bristol-Myers Squibb Company may be unblinded (obtain the randomization 
codes) prior to database lock to facilitate the bioanalytical analysis of 
 and 
immunogenicity. A bioanalytical scientist in the Bioanalytical Sciences department of 
Bristol-Myers Squibb 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 bioanalytical analysis of samples.
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 subject in which knowledge of the IP 
is critical to the subject’s management, the blind for that subject may be broken by the investigator. 
The subject’s safety takes priority over any other considerations in determining if a treatment 
assignment should be unblinded.
Before breaking the blind of an individual subject’s treatment, the investigator should determine 
that the unblinded information is necessary (ie, determine if it will alter the subject’s immediate 
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 subject 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 
principal investigator should only call in for emergency unblinding AFTER the decision to 
discontinue the subject has been made.
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 in order to discuss 
subject safety and whether the subject should remain in the study. The method of unblinding for 
emergency purposes is described in the IRT manual. Subject and unblinded treatment information 
and the reason for the blind being broken, must be recorded on the appropriate study status page 
of the electronic case report form (eCRF). 
In cases of accidental unblinding, contact the medical monitor and ensure every attempt is made 
to preserve the blind. Any request to unblind a subject for nonemergency purposes must be 
discussed with the medical monitor. 
7.3.3
Unblinding for Week 12 Analysis
An unblinded analysis of data through Week 12 will be performed after all subjects complete their 
Week 12 efficacy assessments or have discontinued prior to Week 12. A select group of BMS 
personnel who are not involved in the conduct of the study will review the unblinded results to 
write a clinical study report. Following the Week 12 analysis until the end of the study, the 
investigators, subjects, and clinical study team members who directly cooperate with the site staff 
will continue to remain blinded to the initial treatment assignment. Details of maintaining the blind

A final analysis will be performed after all subjects complete the Week 104 visit or discontinue 
prior to the Week 104 visit, and a clinical study report will be written.
7.4
Dosage Modification and/or Interruption
There is no provision for dose modification of study treatment. 
 
. Modification of other 
background CD therapies or dose regimens is not permitted during study participation. 
 
 
 If a subject’s 
clinical condition worsens (eg, flares) during the Induction Period to the extent that rescue therapy 
is required based on the investigator’s judgment, the subject must discontinue study treatment (IP 
or placebo) for appropriate alternative available treatment. 
If treatment is interrupted for a subject due to an AE, study treatment can be restarted in 
consultation with the medical monitor.
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 subjects. 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 should be contacted immediately.
Study treatment not supplied by BMS will be stored in accordance with the package insert.
IP documentation (whether supplied by BMS or not) must be maintained that includes all processes 
required to ensure drug is properly stored and administered. This includes documentation of drug 
storage, administration and, as applicable, storage temperatures, reconstitution, and use of required 
processes (eg, required diluents, administration sets).
Guidance and information for the final disposition of unused study treatments are provided in 
APPENDIX 2 and the Study Reference Manual.
7.6
Treatment Compliance
Study treatment compliance will be periodically monitored using standard drug accountability 
procedures (comparing the number of capsules returned to number dispensed, considering the 
expected regimen and any reported missed doses). Drug accountability will be reviewed by the 
investigative site staff at each visit to confirm treatment compliance. Site staff will discuss any 
discrepancies with the subject and remind the subject of the importance of compliance with the 
assigned regimen. A real-time monitoring platform may be used.

Concomitant Therapy
All medications taken from within 4 weeks before the first dose of study treatment until 30 days 
after the last dose of IP or last visit (whichever comes later) of study treatment must be recorded 
on the eCRF.
Other than existing treatment for CD (with restrictions as described in the eligibility criteria 
[Section 6]), concomitant medications (prescription, over-the-counter [OTC], or herbal) should be 
administered during the study only if they are prescribed for treatment of specific clinical events. 
7.7.1
Prohibited and/or Restricted Treatments
Restrictions and prohibitions on prior and concomitant medications are as follows:
1) Prior exposure to BMS-986165 is prohibited.
2)
 
 
 
 
 
 
 
 
.
3) Nonsteroidal anti-inflammatory drugs (NSAIDs) may be used on an as-needed basis during 
the study for indications other than CD-related pain (eg, headache), but use is not 
recommended. Assessment of AP is a component of the CDAI and PRO2 instruments, and 
NSAIDs are likely to confound the assessment of efficacy in this study, ie, by improving or 
exacerbating AP related to CD.
4) Prior treatment with specific lymphocyte-depleting agents, such as alemtuzumab, rituximab, 
are prohibited within 12 months prior to the first dose of study treatment during the Induction 
Period.
5) Not applicable per Global Revised Protocol v5.0
6) Receipt of either lymphocyte apheresis or selective monocyte, granulocyte apheresis (eg, 
Cellsorba™) is prohibited. 
7) Required washout periods for individual immunomodulatory and biologic drugs are provided 
in APPENDIX 7.
8) Live vaccines are prohibited 90 days prior to randomization, during the Induction Period or 
Maintenance Period, or within the 2 months after the last dose. Heat-killed, or otherwise 
inactivated, protein or subunit vaccines such as influenza and pneumococcal vaccines, nucleic 
acid vaccines that do not encode potentially infectious virus, and replication-incompetent 
recombinant vector vaccines may be received at any time on study. The effectiveness of 
vaccination in subjects receiving BMS-986165 has not been studied. Similarly, the 
effectiveness of vaccination in subjects who will shortly receive BMS-986165 (eg, subjects in 
the screening period) has not been studied.

Treatment After the End of the Study
 
 
 
 
 
BMS reserves the right to terminate access to BMS-supplied study treatment if any of the following 
occur: a) the study is terminated due to safety concerns or other reasons, including but not limited 
to, lack of efficacy and/or failure to meet study objectives; b) development of BMS-986165 for 
the treatment of CD and/or the development of the compound is terminated for other reasons, 
including but not limited to lack of efficacy and/or failure to meet study objectives; c) the subject 
can obtain medication from a government sponsored or private health program. In all cases, BMS 
will follow local regulations.

pain or tenderness, fever, rash, and/or eosinophilia (> 5%)
•
Any other serious or severe AE or intercurrent illness, that, in the opinion of the investigator 
and after consultation with the medical monitor or designee, indicates that continued 
participation in the study is not in the best interest of the subject. If study treatment is 
discontinued due to an AE, the AE eCRF must be completed to show that the AE caused 
discontinuation
Refer to the Schedule of Activities (Section 2) for data to be collected at the time of treatment 
discontinuation and follow-up and for any further evaluations that can be completed.
In the case of pregnancy, the investigator must immediately notify the BMS medical monitor or 
designee of this event. In the event a female subject becomes pregnant during a clinical trial, the 
study treatment must be discontinued immediately. In most cases, the study treatment will be 
permanently discontinued in an appropriate manner (eg, dose tapering if necessary for subject 
safety). Please call the BMS medical monitor within 24 hours of awareness of the pregnancy. 
All subjects who discontinue BMS-986165 should comply with protocol-specified follow-up 
procedures as outlined in Section 2. The only exception to this requirement is when a subject 
withdraws consent for all study procedures including posttreatment study follow-up or loses the 
ability to consent freely (ie, is imprisoned or involuntarily incarcerated for the treatment of either 
a psychiatric or physical illness). Replacement of subjects is not permitted.

•
Lost to follow-up is defined by the inability to reach the subject after a minimum of 
3 documented phone calls, faxes, or emails as well as lack of response by subject to 1 registered 
mail letter. All attempts should be documented in the subject’s medical records.
•
If it is determined that the subject has died, the site will use permissible local methods to obtain 
date and cause of death.
•
If investigator’s use of third-party representative to assist in the follow-up portion of the study 
has been included in the subject’s informed consent, then the investigator may use a Sponsor 
retained third-party representative to assist site staff with obtaining subject’s contact 
information or other public vital status data necessary to complete the follow-up portion of the 
study. 
•
The site staff and representative will consult publicly available sources, such as public health 
registries and databases, in order to obtain updated contact information. If after all attempts, 
the subject remains lost to follow-up, then the last known alive date as determined by the 
investigator should be reported and documented in the subject’s medical records.

STUDY ASSESSMENTS AND PROCEDURES
Study procedures and timing are summarized in the Schedule of Activities (Section 2). Waivers or 
exemptions from protocol-required evaluations are not allowed.
All immediate safety concerns must be discussed with the medical monitor immediately upon 
occurrence or awareness to determine if the subject should continue or discontinue treatment.
Adherence to the study design requirements, including those specified in the Schedule of Activities 
(Section 2), is essential and required for study conduct.
All screening evaluations must be completed and reviewed to confirm that potential subjects meet 
all eligibility criteria before randomization. The investigator will maintain a screening log to record

details of all subjects screened and to confirm eligibility or record reasons for screening failure, as 
applicable.
Procedures conducted as part of the subject’s routine clinical management (eg, blood count) and 
obtained before signing of the ICF may be used for screening or baseline purposes provided the 
procedure meets the protocol-defined criteria and has been performed within the time frame 
defined in the Schedule of Activities (Section 2).
The study data includes all the information that is collected as a result of the study, including 
subject demographics, disease characteristics, clinical information, blood tests, 
, 
endoscopic videos, intestinal biopsies obtained during endoscopy, and other tests listed in 
Section 2. Study data collected during this study will be used to help understand how BMS-986165 
works in people with CD and related health conditions. The study data may also be used to help 
understand the biology of CD and related health conditions, study test performance in people with 
CD, and for other relevant health research relating to BMS-986165 or these health conditions.
9.1
Efficacy Assessments
Every effort must be made to ensure that the same evaluator(s) complete the assessment for each 
subject. If the evaluator(s) is unable to complete the evaluation, then a qualified individual with 
overlapping experience may perform the evaluation. Documentation of who performed the 
evaluation is to be recorded in source documents. Assessments are to be performed at 
approximately the same time of day throughout the duration of the study. 
Baseline assessments must be performed per protocol (standard of care assessments may not be 
used for baseline). Procedures not specified in the protocol that are part of standard care may be 
performed if they do not interfere with study procedures; any data arising from such procedures 
are not to be reported in the eCRF. 
The following procedures or tools will be used to assess subjects’ CD activity during the study 
(see schedule in Section 2): 
•
CDAI10,15,16 (APPENDIX 10) and PRO212 (
: The CDAI and PRO2 scores will 
be calculated using 7 days of subject diary entries. CDAI also includes additional components, 
as outlined in APPENDIX 10. The following rules apply to the calculation of CDAI and PRO2 
scores: 
For Week 0, if there are < 14 days between the endoscopy date and the visit date, the bowel 
preparation day will serve as the diary reference point; if there are ≥14 days between the 
endoscopy date and the visit date, the Week 0 visit date will serve as the diary reference point.
−
The collection window for subject diary data used for the calculation of CDAI and PRO2 
scores for a study visit (other than Week 0) should be a maximum of 14 days prior to the 
day of the study visit. For study visits that include endoscopy, the final day of diary 
collection is the day before the subject starts bowel preparation for ileocolonoscopy. 
−
CDAI/PRO2 calculation will be performed using the 7 latest days of diary entry in the 
collection window. These days do not have to be consecutive. At least 4 of those 7 days of 
diary data must be collected in the final 7 days of the collection window. If either of these 
criteria are not met, the CDAI/PRO2 score will be counted as “missing.”

If the requirements outlined above are not met, CDAI/PRO2 cannot be calculated for that 
study visit. If this occurs prior to the Week 0 visit, the subject cannot meet Inclusion 
Criterion 2)f), cannot be randomized, and must be screen-failed. 
−
Prior to each scheduled visit at which CDAI/PRO2 is to be calculated, determine whether 
an adequate number of diary entries have been made. If adequate entries have not been 
made, the site should contact the subject to reschedule the visit (or endoscopy, if 
applicable), and the subject should be counseled about proper study procedures.
•
SES-CD17 (APPENDIX 12): The SES-CD assesses the size of mucosal ulcers, the ulcerated 
surface, the endoscopic extension, and the presence of stenosis. This blinded assessment will 
be carried out by Alimentiv Clinical Trials, and the results will be considered final for this 
study.

Section 2 to gather more information about CD activity: 
 
; stool C. difficile; quantitative immunoglobulins (IgM, IgE, IgA, IgG); T, B, and natural 
killer (TBNK) cells; and hematocrit (ie, for CDAI). For the purpose of prompt CDAI score 
calculation from Week 2 through Week 52 and at Week 104, the hematocrit may be performed by 
a local laboratory.
9.3
Adverse Events
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 subject to 
discontinue before completing the study. 
The definitions of an AE or SAE can be found in APPENDIX 3.
 
 
9.3.1
Adverse Events of Interest
AEIs are AEs for a particular product or class of products that a Sponsor may wish to monitor 
carefully. AEIs may be serious or nonserious. Such events may require further investigation to 
better characterize and understand them. In the BMS-986165 clinical development program, 
certain skin-related AEs (eg, acne) and infection AEs have been identified as potential AEIs; 
however, there has been no definitive assessment on the causal relationship between these events 
and treatment with BMS-986165. 
In addition, given that immunomodulation is consistent with the mechanism of action of 
BMS-986165, malignancies are considered to be an important potential risk of therapy with 
BMS-986165 and should be monitored as AEIs. Malignancies were not identified as adverse 
findings in nonclinical studies and no serious adverse reactions of malignancy have been reported 
to date in clinical studies of BMS-986165.
For purposes of reporting these AEIs, specialized eCRF pages will be required to collect additional 
information related to characterization, social/family history, risk factors, signs/symptoms, 
diagnostics, and treatments.

9.3.2
Time Period and Frequency for Collecting AE and SAE Information
The collection of nonserious AE information should begin at initiation of study treatment until the 
follow-up visit at Week 108 or the last visit, at the time points specified in the Schedule of 
Activities (Section 2). Nonserious AE information should also be collected from the start of the 
treatment period at Day 1.
The Reference Safety Information in Appendix 1 of the IB should be used to determine 
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.
All AEs and SAEs related to SARS-CoV-2 infection must be collected from the time of signing 
the consent to the end of the safety follow-up period (30 days after treatment discontinuation) 
 
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.
•
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 module.
•
All SAEs will be recorded and reported immediately to Sponsor or designee but no later than 
24 hours after awareness of the event, as indicated in APPENDIX 3. 
•
The investigator will submit any updated SAE data to the Sponsor or designee immediately 
but no later than  24 hours of updated information being available.
Investigators are not obligated to actively seek AEs or SAEs in former study subjects. However, 
if the investigator learns of any SAE, including a death, at any time after a subject 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 and assessing causality of AEs and SAEs and the procedures for 
completing and reporting/transmitting SAE reports are provided in APPENDIX 3.
9.3.3
Method of Detecting AEs and SAEs
AEs can be spontaneously reported or elicited during open-ended questioning, examination, or 
evaluation of a subject. In order to prevent reporting bias, subjects should not be questioned 
regarding the specific occurrence of 1 or more AEs. 
9.3.4
Follow-up of AEs and SAEs
•
AEs should be followed to resolution or stabilization, or until they are reported as SAEs if they 
become serious (APPENDIX 3).
•
Follow-up is also required for AEs that cause interruption or discontinuation of study treatment 
and for those present at the end of study treatment as appropriate.

•
All identified AEs must be recorded and described on the “adverse events” 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 subject at 
subsequent visits/contacts. All SAEs, and AEIs (as defined in Section 9.3.1) will be followed until 
resolution, until the condition stabilizes, until the event is otherwise explained, or until the subject 
is lost to follow-up, as defined in Section 8.4.
Further information on follow-up procedures is given in APPENDIX 3.
9.3.5
Regulatory Reporting Requirements for SAEs
•
Prompt notification by the investigator to the Sponsor of SAEs is essential so that legal 
obligations and ethical responsibilities towards the safety of subjects 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 Institutional Review Board/Independent Ethics Committee, if 
appropriate according to local requirements.
The Sponsor or designee will be reporting AEs to regulatory authorities and ethics committees 
according to local applicable laws including European Directive 2001/20/EC and FDA Code of 
Federal Regulations (CFR) 21, Parts 312 and 320. Suspected, unexpected, serious adverse 
reactions are a subset of SAEs and will be reported to the appropriate regulatory authorities and 
investigators following local and global guidelines and requirements.
9.3.6
Pregnancy
If, following initiation of the study treatment, it is subsequently discovered that a subject is 
pregnant or may have been pregnant at the time of study exposure, including during at least 
5 half-lives after product administration, the investigator must immediately notify the BMS 
medical monitor/designee of this event and complete and forward a Pregnancy Surveillance Form 
to BMS designee within 24 hours of awareness of the event and in accordance with SAE reporting 
procedures described in APPENDIX 3.
Pregnancy occurring in a female subject is a reason for discontinuation of study treatment (see 
Section 8.1). Protocol-required procedures for study discontinuation (except endoscopy) and 
follow-up should be performed on the subject.
Any pregnancy that occurs in a female partner of a male study subject should be reported to PRA 
Drug Safety. In order for Sponsor or designee to collect any pregnancy surveillance information 
from the female partner, the female partner must sign an ICF for disclosure of this information. 
Information on this pregnancy will be collected on the Pregnancy Surveillance Form.

9.3.7
Laboratory Test Result Abnormalities
The following laboratory test result abnormalities should be captured on the AE eCRF page or 
SAE Report Form electronic, as appropriate. 
•
Any laboratory test result that is clinically significant or meets the definition of an SAE 
•
Any laboratory test result abnormality that required the subject to have study treatment 
discontinued or interrupted
•
Any laboratory test result abnormality that required the subject 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 PRA Drug Safety, 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” is preferable to “low hemoglobin value”). 
9.3.8
Potential Drug-induced Liver Injury 
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential DILI event. All occurrences of potential DILIs, meeting 
the defined criteria, must be reported as SAEs (APPENDIX 3). The Sponsor will require follow-up 
testing when DILI is suspected (eg, HBV DNA, IgM anti-HEV, HEV RNA, IgM & IgG anti-HSV, 
etc).
Potential DILI is defined by presence of all of the following characteristics: 
•
Transaminase (ALT or AST) elevation > 3× ULN
•
Total bilirubin > 2× ULN, without initial findings of cholestasis (elevated serum alkaline 
phosphatase)
•
No other immediately apparent possible causes of transaminase elevation and 
hyperbilirubinemia, including, but not limited to, viral hepatitis, preexisting chronic or acute 
liver disease, or the administration of other drug(s) known to be hepatotoxic 
Identification of a clinically significant elevation(s) in liver-related chemistry or coagulation tests 
(including those defined in Section 8.1, or meeting the definition for potential DILI) should be 
followed by repeat testing of ALT, AST, total bilirubin, ALP, and INR within 48 to 72 hours to: 
(1) confirm the abnormalities, and (2) determine if they are increasing or decreasing.
Investigators should consult with the BMS medical monitor/designee immediately if a subject 
meets the laboratory criteria for potential DILI.

Investigators should consider gathering additional clinical information and laboratory and imaging 
tests to seek other possible causes of the observed liver blood test abnormalities, including (but 
not limited to) acute viral hepatitis, alcoholic and autoimmune hepatitis, biliary obstruction (small 
and large duct), cardiovascular causes (eg, ischemic hepatitis), nonalcoholic steatohepatitis, and 
the effect of concomitant treatments.
A review of all concomitant medications should include herbal medicines, dietary supplements, 
nonprescription OTC medications, including acetaminophen/paracetamol, and occupational 
exposure to chemical agents.
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential DILI event. All occurrences of potential DILIs, meeting 
the defined criteria, must be reported as SAEs (see Section 9.3 and APPENDIX 3 for reporting 
details). All subjects with clinically significant abnormalities in liver-related blood tests, or 
potential DILI, must be followed until all abnormalities return to normal or to the baseline state.
9.3.9
Other Safety Considerations
Any significant worsening noted during interim or final physical examinations, ECG, 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.
9.4
Overdose
For this study, any dose of BMS-986165 that is more than 2-days’ worth of study treatment within 
a 24-hour time period will be considered an overdose.
In the event of an overdose, the investigator should do the following:
1) Contact the medical monitor immediately.
2) Closely monitor the subject for AEs/SAEs and laboratory abnormalities until BMS-986165 
can no longer be detected systemically (at least 3 days).
3) Document the quantity of the excess dose as well as the duration of the overdosing in the eCRF.
Decisions regarding dose interruptions or modifications will be made by the investigator in 
consultation with the medical monitor based on the clinical evaluation of the subject. 
9.5
Safety
Planned time points for all safety assessments are listed in the Schedule of Activities (Section 2). 
All urgent safety concerns must be discussed with the Sponsor immediately upon occurrence or 
awareness to determine if the subject should continue or discontinue treatment.
Safety evaluations that will be performed in addition to AE monitoring are physical examination 
(Section 9.5.1), TB screening (Section 9.5.2), vital signs, ECGs, concomitant medication use, 
laboratory tests (Section 9.5.3).
Planned time points for all safety assessments are listed in the Schedule of Activities.

screening visit is required if not already performed and documented within 6 months of obtaining 
written informed consent. A subject must not have active signs or symptoms of TB, as judged by 
the investigator, to be eligible for the study.
In addition to a complete physical examination and medical history to evaluate exposure to TB, all 
subjects will have a screening test, an IGRA (eg, T-spot® or QuantiFERON®-TB Gold, or
QuantiFERON®-TB Gold Plus) performed centrally. If unable to obtain central laboratory results, 
an IGRA test could be obtained locally, after consultation with the PRA medical monitor. A 
negative IGRA performed within 6 months of the screening visit may be acceptable, provided a 
copy of the report is in the subject's source documentation, and the subject has no new risks for 
LTBI in the interim. A subject with an indeterminate IGRA test result must be retested for 
confirmation. If the second result is again indeterminate, the subject will be excluded from the 
study. If the second result is positive, the subject should be treated as having LTBI provided there 
are no signs or symptoms of active TB. If the second result is negative, the subject may be eligible
provided no other exclusion criterion for TB is met.
9.5.3
Clinical Safety Laboratory Assessments
A central laboratory will perform assessments of safety laboratory assessments (except pregnancy 
tests) and provide reference ranges and laboratory reports. For the purpose of prompt CDAI score 
calculation from Week 2 through Week 52 and at Week 104, the hematocrit may be performed by 
a local laboratory. If the result cannot be obtained before the end of the visit, the subject should 
return the following day for calculation of the CDAI. Investigators must document their review of 
each laboratory safety report. Any laboratory test result that the investigator considers clinically 
relevant for safety is to be recorded on the appropriate AE page of the eCRF (Section 9.3.7). 
Results of clinical laboratory tests performed during the Screening Period must be available prior 
to randomization. The laboratory parameters to be assessed are as follows: 
•
Hematology: hemoglobin, hematocrit, total leukocyte count (including absolute neutrophil 
count and absolute lymphocyte count), platelet count, RBC count, and manual differential 
(separate smear)

Sample Collection and Storage
All requests for access to samples or data for additional research will be vetted through a diverse 
committee of the study Sponsor’s senior leaders in Research and Development (or designee) to 
ensure the research supports appropriate and well-defined scientific research activities. 
•
 
 
Samples kept for future research will be stored at the BMS Biorepository in 
 or 
an independent, BMS-approved storage vendor.
The manager of these samples will ensure they are properly used throughout their usable life and 
will destroy the samples at the end of the scheduled storage period, no longer than 15 years after 
the end of the study or the maximum allowed by applicable law.
Transfers of samples by research Sponsor to third parties will be subject to the recipient’s 
agreement to establish similar storage procedures.
Samples will be stored in a coded fashion, and no researcher will have access to the key. The key 
is securely held by the investigator at the clinical site, so there is no direct ability for a researcher 
to connect a sample to a specific individual.

SARS-CoV-2 Testing
Diagnostic testing for SARS-CoV-2 infection refers to a molecular test (PCR) or antigen test for 
SARS-CoV-2 infection, performed according to local standard of care. PCR testing is preferred. 
Antibody testing is not acceptable as a diagnostic test for SARS-CoV-2 infection.
Diagnostic testing for SARS-CoV-2 infection should be performed as close as possible to 
randomization and must be confirmed as “negative” prior to randomization.
Subjects will be screened for AEs (including signs and symptoms of COVID-19) at each study 
visit. Subjects will be instructed to contact the investigator at any time if they develop an 
intercurrent illness, including a diagnosis, or signs and symptoms of COVID-19, which will enable 
close monitoring and additional screening for the infection between study visits. 
The investigator should obtain a diagnostic test for SARS-CoV-2 infection if COVID-19 is 
clinically suspected. If a subject report having recent direct contact with someone known to have 
COVID-19, the subject should undergo diagnostic testing for SARS-CoV-2. 
IP should be temporarily interrupted in subjects who present with signs and/or symptoms 
suggestive of COVID-19 while the subject undergoes diagnostic testing for SARS-CoV-2 
infection. This testing should be performed as soon as feasible.

IP must be temporarily interrupted in subjects who test positive for SARS-CoV-2 infection. Such 
subjects should continue to be followed by the investigator. Such subjects must meet all the criteria 
outlined below prior to restarting IP. The final decision to restart IP must be made in consultation 
with the BMS medical monitor/designee.
Subjects with a positive diagnostic test for SARS-CoV-2 infection during the screening period 
may be considered eligible for the study once they meet all eligibility criteria related to active 
infection, and after meeting the criteria outlined below.
Criteria to rescreen or recommence IP after a positive SARS-CoV-2 test:
•
Negative follow-up molecular test for COVID-19 based on institutional, local, or regional 
guidelines, and
•
At least 10 days (20 days for severe/critical illness) have passed since symptoms first appeared 
or positive test result, and
•
At least 24 hours have passed since last fever without the use of fever-reducing medications, 
and
•
Symptoms (eg, cough, shortness of breath) have resolved, and
•
In the opinion of the investigator, there are no COVID-19 sequelae that may confound the 
assessment of safety or efficacy within the study and place the subject at a higher risk from 
receiving investigational treatment, and
•
The above must be discussed with the BMS medical monitor prior to rescreening or 
recommencing IP (as applicable).

STATISTICAL CONSIDERATIONS
10.1
Sample Size Determination 
Approximately 240 subjects will be randomized into 1 of 3 treatment arms on Day 1 in a 3:3:2 
ratio, resulting in approximately 90 subjects in each BMS-986165 dose arm and 60 subjects in the 
placebo arm. Sample size is based on the power to compare the response rates of the BMS-986165 
3 mg BID treatment arm with placebo, or the BMS-986165 6 mg BID treatment arm with placebo 
for each of the co-primary endpoints at Week 12 (Day 85). A Bonferroni adjustment will be used 
to compare the BMS-986165 3 mg BID and BMS-986165 6 mg BID active treatment groups to 
placebo. Response rates for clinical remission and endoscopic response are based on published 
response rates using similar endpoints.27
 
 
. With a 2-sided chi-square test at a significance level 0.025 and a sample 
size of 90 subjects for each BMS-986165 treatment arm and 60 subjects in the placebo arm, 
 
 
 Additionally, with a 
2-sided chi-square test at a significance level of 0.025 and a sample size of 90 subjects for each 
BMS-986165 treatment arm, and 60 in the placebo arm,

Efficacy Analyses
The SAP will be developed and finalized before database lock for the interim analysis, if any, (see 
Section 10.6.3), and will provide detailed specifications of the analysis of all efficacy endpoints 
and safety and will also describe the selection of subjects to be included in the analyses and 
procedures for accounting for missing data. This section provides a summary of planned statistical 
analyses of the efficacy endpoints.
Categorical data will be summarized as frequency counts and percentages. Continuous data will 
be summarized using n, mean, standard deviation, median, minimum, and maximum unless 
otherwise specified. Subjects who continue the randomized double-blind treatment group will be 
summarized according to their original treatment assignment during the Maintenance Period. 
Subjects who switch to open-label treatment of the 6 mg BID dose at Week 12 or Week 26 will be 
summarized separately.
Subjects who were enrolled prior to Protocol v3.0 and were assigned to BMS-986165 12 mg QD 
will not be included in the primary efficacy analysis. Further details of summarizing data for these 
subjects will be included in the SAP.
10.4.1
Co-primary Endpoint Analyses
The co-primary endpoints, the proportion of subjects achieving clinical remission at Week 12 and 
the proportion of subjects achieving endoscopic response at Week 12, will be analyzed separately 
using stratified Cochran-Mantel-Haenszel (CMH) tests stratified by geographic region (US, Japan, 
 
 
 Differences in response rates and corresponding 2-sided 95% and 97.5% 
confidence intervals (CIs) will be provided along with the point estimates and corresponding 
95% and 97.5% CIs for each treatment group using a binomial model. The odds ratio (odds in an 
active treatment group/odds in placebo), and the corresponding 2-sided 95% and 97.5% CIs will 
be provided as well.
10.4.2
Imputation Methods for Co-primary Endpoints
Non-responder imputation (NRI) will be used for co-primary efficacy endpoints for subjects who 
discontinue treatment prior to Week 12 and have no Week 12 assessments after treatment 
discontinuation, 
 initiate use or 
continue to use prohibited medications in the Induction Period, require surgical procedure(s) for 
treatment of CD or related complications in the Induction Period, or have otherwise missing 
endpoint data at the Week 12 (Day 85) timepoint, ie, the NRI will be the primary method of 
imputation for the co-primary efficacy endpoints.

 baseline value will be added into the model as a covariate. Treatment differences 
based on least squares means and the corresponding 2-sided 95% and 97.5% CIs will be provided 
for the difference between each active treatment and placebo.
10.4.5
Imputation Methods for Secondary Endpoints
NRI will be used for subjects who discontinue treatment prior to Week 12 and have no Week 12 
assessments after treatment discontinuation,
 
 initiate use or continue to use prohibited medications in the Induction Period, 
require surgical procedure(s) for treatment of CD of related complications in the Induction Period, 
or have otherwise missing endpoint data at the specified timepoint for binary endpoints.
For continuous secondary efficacy endpoints, a multiple imputation (MI) analysis will be used for 
subjects who discontinue study treatment prior to Week 12 and have no Week 12 assessments after 
treatment 
discontinuation, 
and 
for 
subjects 
who 
require 
a 
protocol-prohibited 
medication/therapy/surgical procedure that could improve the disease prior to the Week 12 
endpoint, or who have otherwise missing endpoint data at the specified time point for continuous 
endpoints.

Interim Analysis
In addition to the primary efficacy analysis conducted when 12-week data are available for all 
randomized subjects, interim analyses may be performed. The purpose of interim analyses will be 
to help in early planning for further clinical development of the compound.
To maintain the overall probability of Type I error at the specified 0.05 level, a modified 
Haybittle-Peto method28 will be used as the alpha-spending function, which assigns alpha=0.001 
to each interim analysis, and the remaining alpha to the final (Week 12) analysis of the primary 
efficacy endpoints.
The SAP for the study will be finalized prior to any interim analysis. The details (including the 
timing) of the interim analyses will be provided in an Interim Analysis Plan prior to the database 
lock for any interim analysis. The results of the interim analyses will be reviewed by an unblinded 
internal BMS team that is independent of the study team responsible for the conduct of the study. 
The study team members, including the medical monitors and other study personnel, will remain 
blinded and will not have access to any unblinded interim analysis results or data until the final 
database lock for the Week 52 data has occurred.

The sponsor or designee will provide the investigator with an appropriate sample 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.
The investigator or his/her representative must:
•
Obtain IRB/IEC written approval/favorable opinion of the written ICF and any other 
information to be provided to the subject prior to the beginning of the study and after any 
revisions are completed for new information.
•
Provide a copy of the ICF and written information about the study in the language in which 
the subject is proficient prior to clinical study participation. The language must be nontechnical 
and easily understood. 
•
Explain the nature of the study to the subject and answer all questions regarding the study.
•
Inform subject that his/her participation is voluntary. Subject will be required to sign a 
statement of informed consent that meets the requirements of 21CFR50, local regulations, ICH 
guidelines, Health Insurance Portability and Accountability Act (HIPAA) requirements, where 
applicable, and the IRB/IEC or study center.
•
Allow time necessary for subject to inquire about the details of the study.
•
Obtain an ICF signed and personally dated by subject and by the person who conducted the 
informed consent discussion. 
•
Include a statement in subject’s medical record that written informed consent was obtained 
before subject was enrolled in the study and the date the written consent was obtained. The 
authorized person obtaining the informed consent must also sign the ICF.
•
Re-consent subject to the most current version of the ICF(s) during his/her participation in the 
study, as applicable.
Revise the ICF whenever important new information becomes available that is relevant to the 
subject’s consent. The investigator, or a person designated by the investigator, should fully inform 
the subject, of all pertinent aspects of the study and of any new information relevant to the subject’s 
willingness to continue participation in the study. This communication should be documented. 
The confidentiality of records that could identify subjects must be protected, respecting the privacy 
and confidentiality rules applicable to regulatory requirements, the subjects’ signed ICF and, in 
the US, the subjects’ signed HIPAA Authorization.
The ICF must also include a statement that BMS and local and foreign regulatory authorities have 
direct access to subject records. 
The rights, safety, and well-being of the study subjects are the most important considerations and 
should prevail over interests of science and society.

Data reported on the case report form (CRF) or entered in the electronic CRF (eCRF) that are 
transcribed from source documents must be consistent with the source documents or the 
discrepancies must be explained. 
•
The investigator may need to request previous medical records or transfer records, depending 
on the study. Also, current medical records must be available.
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 
records).
When paper records from such systems are used in place of electronic format to perform regulated 
activities, such paper records should be certified copies. A certified copy consists of a copy of 
original information that has been verified, as indicated by a dated signature, as an exact copy 
having all of the same attributes and information as the original. 
STUDY TREATMENT RECORDS
Records for study treatments (whether supplied by BMS, its vendors, or the site) must substantiate 
study treatment integrity and traceability from receipt, preparation, administration, and through 
destruction or return. Records must be made available for review at the request of BMS/designee

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 serious AEs (SAEs) and 
pregnancy, which will be reported on the electronic SAE form and paper Pregnancy Surveillance 
Form, respectively. If an electronic SAE form is not available, a paper SAE form can be used. 
The confidentiality of records that could identify subjects 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 and 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.

or designee.
STUDY AND SITE START AND CLOSURE
The Sponsor/designee reserves the right to close the study site or to terminate the study at any time 
for any reason at the sole discretion of the Sponsor. Study sites will be closed upon study 
completion. A study site is considered closed when all required documents and study supplies have 
been collected and a study-site closure visit has been performed.
The investigator may initiate study-site closure at any time, provided there is reasonable cause and 
sufficient notice is given in advance of the intended termination.
Reasons for the early closure of a study site by the Sponsor or investigator may include, but are 
not limited to:
•
Failure of the investigator to comply with the protocol, the requirements of the IRB/IEC or 
local regulatory authorities, the Sponsor’s procedures, or GCP guidelines
•
Inadequate recruitment of subjects by the investigator
•
Discontinuation of further study intervention development
If the study is prematurely terminated or suspended, the Sponsor shall promptly inform the 
investigators, the IECs/IRBs, the regulatory authorities, and any contract research organization(s) 
used in the study of the reason for termination or suspension, as specified by the applicable 
regulatory requirements. The investigator shall promptly inform the subject and should assure 
appropriate subject therapy and/or follow-up.
DISSEMINATION OF CLINICAL STUDY DATA

An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a 
preexisting medical condition in a clinical investigation subject administered study treatment 
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 treatment, whether or 
not considered related to the study treatment.
Events Meeting the AE Definition
•
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
results from other safety assessments (eg, 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
A serious adverse event (SAE) is defined as any untoward medical occurrence that, at any 
dose:
Results in death
Is life-threatening (defined as an event in which the subject 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 subject 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. A potential drug-induced liver injury (DILI) is also considered an important 
medical event. (See Section 9.3.8 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 9.3.6 for reporting pregnancies).

EVALUATING AES AND SAES
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 Brochure IB 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. 
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, 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 used 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.
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 to PRA 
Drug Safety within 24 hours of awareness of the event.
•
SAEs must be recorded on the SAE Report Form. 
−
The required method for SAE reporting is through the electronic case report form 
(eCRF).
−
The paper SAE Report Form is intended only as a back-up option when the electronic 
data capture system is unavailable/not functioning for transmission of the eCRF to BMS 
(or designee).
♦In this case, the paper form is transmitted via email or confirmed facsimile 
transmission.
•
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:

APPENDIX 5
WOMEN OF CHILDBEARING POTENTIAL DEFINITIONS AND 
METHODS OF CONTRACEPTION
Appendix 5 provides general information and definitions related to Woman of Childbearing 
Potential and methods of contraception that can be applied to most clinical trials. For information 
specific to this study regarding acceptable contraception requirements for female and male 
subjects, refer to Section 6.1 of the protocol. Only the contraception methods as described in 
Section 6.1 are acceptable for this study.
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 subject’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, females 
under the age of 55 years must have a serum follicle-stimulating hormone (FSH) level 
> 40 mIU/mL to confirm menopause.
Note: Females 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. Suggested 
guidelines for the duration of the washout periods for HRT types are presented below. Investigators 
should use their judgement 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 timepoint where the Investigational Medicinal Product 
(IMP) or any active major metabolites have 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.
CONTRACEPTION GUIDANCE FOR FEMALE SUBJECTS OF CHILDBEARING
POTENTIAL
At least an acceptable, less than highly effective means of contraception should be continued until 
the end of treatment.
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 subjects in studies where hormonal contraception is permitted by the study 
protocol.)b
−
Oral (birth control pills)
−
Intravaginal (rings)
−
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 subjects 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 
•
Intrauterine device (IUD)b
•
Intrauterine hormone-releasing system (IUS)c
•

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. 
•
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 drug. 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 subject.
•
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 subjects who choose complete abstinence must continue to have pregnancy tests, 
as specified in Section 2 of the protocol. 
•
Acceptable alternate methods of highly effective contraception must be discussed in the 
event that the WOCBP subjects chooses to forego complete abstinence 
•
Periodic abstinence (including, but not limited to, calendar, symptothermal, postovulation 
methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea 
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 subjects 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. For information specific to this study regarding permissibility of 
hormonal contraception, refer to .Sections 6.1 INCLUSION CRITERIA and 7.7.1 PROHIBITED AND/OR 
RESTRICTED TREATMENTS of the protocol.
c Intrauterine devices and 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 
subjects in studies where hormonal contraception is prohibited.)

INTERPRETATION OF HBV AND HCV TEST RESULTS
I. HBV
As BMS-986165 is predicted to have immunomodulatory effects in this study, subjects with 
potentially active hepatitis B (HBV) infection and subjects at risk of reactivation of HBV infection 
will be excluded (see Section 6.2).
Hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface 
antibody (HBsAb) are evaluated at screening, with reflex to HBV DNA testing in subjects with 
HBsAg negative, anti-HBc positive serology (as listed in the “Interpretation unclear” scenario, 
below). Notes on interpretation of HBV serology within this study are given below:
Susceptible – does not meet exclusion criteria on HBV
•
HBsAg negative
•
anti-HBc negative
•
HBsAb negative
Immune due to natural infection - does not meet exclusion criteria on HBV
•
HBsAg negative
•
anti-HBc positive
•
HBsAb positive
Immune due to hepatitis B vaccination - does not meet exclusion criteria on HBV
•
HBsAg negative
•
anti-HBc negative
•
HBsAb positive
Acutely infected – meets exclusion criteria on HBV
•
HBsAg positive
•
anti-HBc positive
•
IgM anti-HBc positive
•
HBsAb negative
Chronically infected - meets exclusion criteria on HBV
•
HBsAg positive
•
anti-HBc positive
•
IgM anti-HBc negative
•
HBsAb negative
Interpretation unclear
•
HBsAg negative
•
anti-HBc positive
•
HBsAb negative
HBV DNA testing will be performed in subjects with a negative HBsAg, but a positive anti-HBc 
antibody at screening. Subjects with detectable HBV DNA at screening are excluded. Subjects in 
this subgroup may be eligible for inclusion if HBV DNA is undetectable on this assay during 
screening.
Subjects with HBsAg negative, anti-HBc positive serology and undetectable HBV DNA at 
screening will have follow-up HBV DNA testing throughout their participation in the study, as 
detailed in the Schedule of Activities (Section 2).

Subjects in this subgroup who have a clinical response at Week 12, who then enter the 
Maintenance Period and subsequently lose response and enter the open-label LOR arm will 
have additional HBV DNA testing at the first 3 study visits after entry to the LOR arm.
•
Subjects in this subgroup who do not have a clinical response at Week 12 and who enter 
the open-label BMS-986165 6 mg BID PO study arm, will have HBV DNA testing at 
Weeks 16, 22 and 26, and approximately every 3 months thereafter.
•
Subjects who enter the open-label extension period at Week 52 will have HBV DNA tested 
at Weeks 56, 60 and 64, and approximately every 3 months thereafter.
•
If subjects in this subgroup have detectable HBV DNA at any time, they must permanently 
discontinue study treatment, enter the Post-treatment Follow-up Period and the investigator 
should consider referring them for appropriate specialty care and follow-up.
II. HCV
Testing for HCV is a two-step process: (i) anti-HCV antibody, and (ii) HCV RNA.
Subjects with a negative anti-HCV antibody may be eligible for the study.
Subjects with a positive or indeterminate anti-HCV antibody require additional HCV RNA testing 
to determine eligibility. Subjects with negative or undetectable HCV RNA may be eligible for the 
study. Subjects with positive or detectable HCV RNA have HCV infection, are excluded from the 
study and should be referred for appropriate assessment and consideration for treatment. 
Subjects who were previously treated with an approved, treatment regimen for HCV infection may 
be eligible to participate in the study provided they achieve a Week 24 Sustained Virologic 
Response; that is negative or undetectable HCV RNA 24 weeks after completion of a full course 
of an approved treatment regimen for HCV infection. Such subjects must be discussed with the 
medical monitor prior to screening.

APPENDIX 10
CROHN'S DISEASE ACTIVITY INDEX VARIABLES
The CDAI score consists of eight variables including 4 subject-reported outcomes. Variables 1, 2, 
3, and 5 will be obtained from the subject diary, as outlined in Section 9.1. The Standard Height 
and Weight Table (below) must be used to calculate variable 8. The score from each variable is 
weighted by applying the multiplier shown. The total CDAI score is then determined by calculating 
the sum of the individual, weighted scores.

APPENDIX 19
COVID-19 VACCINES
If a subject has received a specific coronavirus disease of 2019 (COVID-19) vaccination, the type 
of vaccine received should be recorded on the concomitant medication page, if given during the 
study, or the past history page, if given prior to enrollment.
•
Administration of a live vaccine is prohibited 90 days prior to the randomization visit; during 
the induction period, maintenance period, or open-label extension (OLE) period; or within 
2 months after the last dose of IP.
•
Administration of a non-live vaccine is allowed during the study. However, the efficacy and 
safety of non-live vaccines (including non-live COVID-19 vaccines) in subjects receiving 
BMS-986165 is unknown.
•
The following are NOT live vaccines: inactivated vaccines (eg, heat-killed and formalin-killed 
vaccines), subunit vaccines (eg, influenza and pneumococcal vaccines), toxoid vaccines, 
nucleic acid vaccines that do not encode potentially infectious virus (eg, Pfizer/BioNTech and 
Moderna COVID-19 vaccines) and replication-incompetent recombinant vector vaccines (eg, 
AstraZeneca/University of Oxford COVID-19 vaccine).
•
For COVID-19 vaccines requiring more than one dose, the full series (eg, both doses of a 
2-dose series) should be completed prior to enrollment when feasible, and when a delay in 
enrollment would not put the study subject at risk. Ideally, AEs attributable to a vaccine should 
have resolved prior to enrollment.
•
Administration of vaccinations must be reported along with dosage information, dates of 
administration and vaccine name/trade name on the Prior and Concomitant Medications form. 
A separate logline should be entered for each vaccine administered with the dose number 
following the vaccine name/trade name.
Please contact the medical monitor with any questions related to COVID-19 vaccines.

CLOSTRIDIUM DIFFICILE INFECTION SCREENING
Subjects must provide a stool sample for Clostridium difficile (C. difficile) testing at the screening 
visit. The central lab performs glutamate dehydrogenase (GDH) and C. difficile toxin analysis on 
the sample to confirm the subject is negative for the bacterium. The following chart presents the 
procedures to be followed to determine eligibility:
C. difficile = Clostridium difficile; GDH = glutamate dehydrogenase; PCR = polymerase chain reaction
Please contact the medical monitor with any questions related to C. difficile testing or infection.

PROTOCOL AMENDMENT SUMMARY OF CHANGE HISTORY
Overall Rationale for the Protocol Amendment 4, 06-Aug-2021
The primary purpose of this protocol amendment is to include the following updates:
•
Reconfiguration of secondary and exploratory study endpoints in response to expert consensus 
on treatment targets in inflammatory bowel disease (IBD)
•
 
•
Removal of exclusion criterion that prohibited the participation of subjects who had previously 
experienced inadequate response or loss of response to ustekinumab
•
Addition of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diagnostic 
testing, as well as an exclusion criterion and study procedures pertaining to SARS-CoV-2 
infection 
•
Inclusion of coronavirus disease 2019 (COVID-19) benefit-risk information and vaccination 
guidelines
•
 
 
The amendment will be implemented after the Investigator receives all appropriate agency and 
IRB/EC approvals.
Generally, only major additions and deletions are provided in this summary of changes document, 
and all minor grammatical, formatting, rephrasing, stylistic changes, or clarifications, as well as 
organizational changes are not included. All changes applied to the protocol body were applied to
