SYNOPSIS
Clinical Protocol IM128035
Protocol Title: A Phase II, Randomized, Multi-Center, Double-Blind, Placebo Controlled Study to Evaluate the 
Efficacy and Safety of BMS-931699 (lulizumab) or BMS-986142 in Subjects with Moderate to Severe Primary 
Sjogren's Syndrome
Investigational Product(s), Dose and Mode of Administration, Duration of Treatment with Investigational 
Product(s):
BMS-931699 (lulizumab) is an anti-human cluster of differentiation (CD)28 receptor antagonist Vk domain 
antibody (dAb), formatted with 40 kDa branched polyethylene glycol (PEG). It will be administered subcutaneously 
(SC) at a dose of 12.5 mg weekly in a double-blind fashion for 12 weeks.
BMS-986142 is a reversible Bruton’s tyrosine kinase (BTK) inhibitor that will be administered orally at a dose of 
350 mg daily in a double-blind fashion for 12 weeks. 
Study Phase: II
Research Hypothesis: Treatment with BMS-931699 (lulizumab) or BMS-986142 for 12 weeks is more effective 
than placebo in decreasing the ESSDAI score in subjects with moderate to severe primary Sjögren’s syndrome
(pSS).
Objectives:
Primary: To evaluate the efficacy of treatment with either lulizumab or BMS-986142 versus placebo in subjects 
with moderate to severe primary Sjögren’s syndrome as measured by the change from baseline in ESSDAI at 
Week 12 between active treatment arms (lulizumab or BMS-986142, respectively) and the placebo arm.
Secondary:
To assess the:

Change from baseline in ESSPRI score at Week 12

Proportion of subjects with a 3 point improvement from baseline in ESSDAI at Week 12

Proportion of subjects with a 1 point improvement from baseline in ESSPRI at Week 12

Proportion of subjects with both 3 point improvement in ESSDAI and 1 point improvement in ESSPRI from 
baseline at Week 12

Change from baseline in ESSDAI scores at Week 4 and Week 8

Change from baseline in ESSPRI scores at Week 4 and Week 8

Change from baseline in ESSPRI components (Dryness, Fatigue, and Pain) at Week 4, 8 and 12

Change from baseline in unstimulated and stimulated salivary flow rate at Weeks 4, 8, and 12

Change from baseline in ocular surface staining, Schirmer’s test, and tear-break up time test at Weeks 4, 8,
and 12

Safety and tolerability of lulizumab or BMS-986142 in subjects with moderate to severe pSS, as measured by 
adverse events, laboratory parameters, vital signs, physical exams, and ECGs 

Change from baseline in patient and physician assessments of disease activity:
-
Numeric rating scale (NRS) scores for mouth, eye and vaginal dryness
-
Subject global assessment of disease activity (SubGDA) and physician global assessment of disease 
activity (phyGDA)

Study Design:
This is a 12-week randomized, double-blind, placebo-controlled, parallel group study with adaptive design features 
based on an interim analysis (IA). The study will initially have a 28-day Screening Period followed by up to 
12 weeks of double-blind treatment with either lulizumab, BMS-986142, or placebo.
Screening Period: The standard duration of the Screening Period is up to 28 days (4 weeks), with up to two 
Screening Visits allowed for subjects who require adjustment of oral corticosteroids or who are taking 
hydroxychloroquine. Subjects who are on oral corticosteroids at a dose higher than 10 mg/day will require a taper at 
the beginning of the Screening Period to a stable dose of no more than 10 mg/day of prednisone (or equivalent) by at 
least 14 days prior to dosing (Day -14), and will need to be reevaluated at a second screening visit prior to 
randomization (Day 1). Subjects who are taking hydroxychloroquine (HCQ, Plaquenil) at screening who meet the 
study criteria will be required to return for a second visit during the screening period to collect baseline HCQ PK 
samples. Should more time be needed, the duration of the Screening Period may be extended up to another week 
(total of 5 weeks or 35 days) depending on dose stabilization, technical issues, or subject scheduling.
Study Summary: Subjects with moderate to severe primary Sjögren’s syndrome will receive lulizumab, 
BMS-986142, or matching placebos for up to 12 weeks, followed by a 6-week follow-up period. 
Upon meeting the Inclusion/Exclusion criteria, approximately 75 subjects will be equally randomized to 1 of the 
3 treatment arms as shown in Figure 1 below.
An interim analysis will be conducted after at least 30 subjects reach Week 12 (complete 12 weeks of treatment) and 
complete the specified assessments for the Week 12 ESSDAI score. The interim analysis will be conducted in a fully 
blinded manner such that treatment group assignments of study subjects are not known and are not used in any 
manner in the analysis. A blinded examination of the variance of the primary endpoint will be performed and 
compared to the assumption used in planning the study. If this comparison suggests the initial assumption was 
substantially too low, the total study sample size may be increased by up to 45 additional subjects (ie, to a maximum 
of 120 subjects in total) to maintain adequate statistical power. The blinded IA will not interfere or alter any 
subject’s treatment, that is, subjects who were enrolled before the IA is completed will continue the originally 
assigned treatment arm if they have received at least 1 treatment and the dose is considered safe.
Ongoing assessment of safety will be performed by an independent Data Monitoring Committee (DMC). The DMC 
may make recommendations to the Sponsor regarding conduct of the study based on safety observations.

Study Design Schematic
Duration of Study:
The approximate duration of the study is up to a 5-week screening period (35 days), a 12-week double-blind 
treatment period (84 days), and 6 weeks of follow-up (42 days), for a total of up to 23 weeks (161 days).
Number of Subjects:
Approximately 75 subjects will be randomized across the three arms of this study. The study will utilize an equal 
randomization scheme (1:1:1) that will result in approximately 25 subjects in each arm. An interim analysis will be 
conducted in a fully blinded manner to examine the variability of the primary outcome measure and compare that to 
the assumption used in planning the study. If this comparison suggests the initial assumption was substantially too 
low, the total study sample size may be increased by up to 45 additional subjects (ie, to a maximum of 120 subjects 
in total) to maintain adequate study power.
Study Population:
Men or women (not nursing or pregnant) ages 18 to 70 years old (inclusive at time of randomization), diagnosed 
with primary Sjögren’s syndrome by the 2016 ACR-EULAR Classification Criteria, for at least 16 weeks prior to 
screening. Women of childbearing potential must use an acceptable method of highly effective contraception to 
avoid pregnancy for the duration of dosing and at least 65 days after the last dose of study medication.
Key Inclusion Criteria:
1. Subjects diagnosed or classified as having moderate to severe primary Sjögren’s syndrome based on the 2016
ACR-EULAR Classification Criteria for Sjögren’s syndrome, with disease duration from time since diagnosis of 
at least 16 weeks prior to the Screening Visit
2. ESSDAI 5; including disease activity (any score > 0) in at least one of the following domains: Glandular, 
Articular, Hematological, Biological, Lymphadenopathy
3. Positive anti-SS-A/Ro or anti-SS-B/La autoantibody
4. Unstimulated whole saliva secretion > 0.01 mL/min

Study Assessments:
Efficacy will be assessed using the ESSDAI and ESSPRI scores, as well as various other pharmacodynamic (PD), 
clinical, and patient reported measures of dryness and disease activity as listed under the objectives and endpoints.
Safety (through reporting of adverse events, clinical laboratory results, physical examination, which includes vital 
signs and electrocardiograms [ECGs]), PK, pharmacodynamics, exploratory biomarkers, target engagement, and 
immunogenicity will also be assessed.
Statistical Considerations:
Sample Size:
The sample size calculation is based on the power to compare change from baseline in ESSDAI at Week 12 between 
active treatment arms (lulizumab or BMS-986142) and the placebo arm. With a two-sided, two-sample t-test at 
significance level 0.05, data from 25 treated subjects per arm will provide approximately 90% power to detect a 
placebo-adjusted 3-point decrease from baseline for each active treatment group, assuming common standard 
deviations of 3.2. In addition, the Hochberg’s step-up procedure will be used to adjust the multiplicity due to the 
comparison of two active treatment arms (lulizumab or BMS-986142) to the placebo arm.
The primary efficacy analysis will be conducted on all randomized subjects who received at least one dose of study 
drug.
An interim analysis will be conducted after at least 30 subjects reach Week 12 (complete 12 weeks of treatment) and 
complete the specified assessments for ESSDAI. The interim analysis will be conducted in a fully blinded manner 
such that treatment group assignments of study subjects are not known and are not used in any manner in the 
analysis. A blinded examination of the variance of the primary endpoint will be performed and compared to the 
assumption used in planning the study. If this comparison suggests the initial assumption was substantially too low, 
the total study sample size may be increased by up to 45 additional subjects (ie, to a maximum of 120 subjects in 
total) to maintain the desired study power. Regardless of the outcome from the blinded examination of variability, 
the study sample size will not be decreased. A maximum study sample size of 120 subjects in total, ie, 40 subjects 
per arm, can provide each active treatment arm 79% power to detect a placebo-adjusted 3-point decrease from 
baseline for common standard deviations as large as 4.8, using a two-sided two-sample t-test comparing each active 
treatment arm to placebo at significant level 0.05.

2.2
Institutional Review Board/Independent Ethics Committee
Before study initiation, the investigator must have written and dated approval/favorable opinion 
from the IRB/IEC for the protocol, consent form, subject recruitment materials 
(eg, advertisements), and any other written information to be provided to subjects. The 
investigator or BMS should also provide the IRB/IEC with a copy of the IB or product labeling 
information to be provided to subjects and any updates.
The investigator or BMS should provide the IRB/IEC with reports, updates and other 
information (eg, expedited safety reports, amendments, and administrative letters) according to 
regulatory requirements or institution procedures.
2.3
Informed Consent
Investigators must ensure that subjects are clearly and fully informed about the purpose, potential 
risks, and other critical issues regarding clinical studies in which they volunteer to participate.
In situations where consent cannot be given to subjects, their legally acceptable representatives 
(as per country guidelines) are clearly and fully informed about the purpose, potential risks, and 
other critical issues regarding clinical studies in which the subject volunteers to participate.
BMS will provide the investigator with an appropriate (ie, Global or Local) sample informed 
consent form which will include all elements required by ICH, GCP and applicable regulatory 
requirements. The sample informed consent form will adhere to the ethical principles that have 
their origin in the Declaration of Helsinki.
Investigators must:

Provide a copy of the consent form and written information about the study in the language 
in which the subject is most proficient prior to clinical study participation. The language 
must be non-technical and easily understood

Allow time necessary for subject or subject's legally acceptable representative to inquire 
about the details of the study

Obtain an informed consent signed and personally dated by the subject or the subject's 
legally acceptable representative and by the person who conducted the informed consent 
discussion

Obtain the IRB/IEC’s written approval/favorable opinion of the written informed consent 
form and any other information to be provided to the subjects, prior to the beginning of the 
study, and after any revisions are completed for new information

If informed consent is initially given by a subject’s legally acceptable representative or 
legal guardian, and the subject subsequently becomes capable of making and 
communicating his or her informed consent during the study, consent must additionally be 
obtained from the subject.

Revise the informed consent 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 or the subject's legally acceptable 
representative or legal guardian, 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 consent form must also include a statement that BMS and 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.

INVESTIGATIONAL PLAN
3.1
Study Design and Duration
This is a 12-week randomized, double-blind, placebo-controlled, parallel group study with 
adaptive design features based on an interim analysis (IA). The study will initially have a 28-day 
screening period followed by up to 12 weeks of double-blind treatment with either lulizumab, 
BMS-986142, or a matching placebo.
Screening period:
The standard duration of the Screening Period is up to 28 days (4 weeks), with up to two 
Screening Visits allowed for subjects who require adjustment of oral corticosteroids or who are 
taking HCQ. Subjects who are on oral corticosteroids at a dose higher than 10 mg/day will 
require a taper at the beginning of the Screening Period to a stable dose of no more than 
10 mg/day of prednisone (or equivalent) for least 14 days prior to dosing (Day -14), and will 
need to be reevaluated prior to randomization (Day 1). Subjects who are taking HCQ at 
screening who meet the study criteria will be required to return for a second visit during the 
screening period to collect baseline HCQ PK samples as described in Section 5.5 (these subjects 
should bring their daily dose of HCQ to the clinical site to be administered at the site). Should 
more time be needed, the duration of the Screening Period may be extended up to another week 
(total of 35 days or 5 weeks) depending on dose stabilization, technical issues, or subject 
scheduling. Study procedures will occur as specified in Table 5.1-1.
Double-blind treatment period:
Upon meeting the Inclusion/Exclusion criteria, approximately 75 subjects with moderate to 
severe pSS will be equally randomized to 1 of 3 treatment arms (lulizumab, BMS-986142, or 
matching placebos) for up to 12 weeks of treatment, followed by a 6 week follow-up period after 
completion 
of
treatment. 
During 
this 
period, 
the 
dose
of 
oral 
corticosteroids, 
hydroxychloroquine, pilocarpine, cevimeline, cyclosporine eye drops, lifitegrast, autologous 
serum eye drops, oral and ocular lubricants and/or NSAIDs should remain stable. No additional 
immunosuppressive medications may be started unless indicated for the treatment of adverse

events. Analgesics are permitted with certain restrictions (see Section 3.4.1.2). Study procedures 
will occur as specified in Table 5.1-2, Table 5.5-1, and Table 5.6-1.
If a subject discontinues early from treatment, all procedures scheduled for the End of 
Week 12/End of treatment visit should be performed at the time of actual discontinuation/end of 
treatment.  At the end of the double blind treatment period, alternate therapies for Sjögren’s 
syndrome should be discussed with subjects.
Interim analysis:
An IA of all accumulated primary endpoint (ESSDAI) data up to Week 12 will be performed 
after at least 30 subjects reach Week 12 (complete 12 weeks of treatment) and complete the 
specified assessments for the Week 12 ESSDAI score. The interim analysis will be conducted in 
a fully blinded manner, such that treatment group assignments of study subjects are not known 
and are not used in any manner in the analysis. A blinded examination of the variance of the 
primary endpoint will be performed and compared to the assumption used in planning the study. 
Based on the results, the study sample size may be increased to maintain adequate statistical 
power. The blinded IA will not interfere or alter any subject’s treatment, that is, subjects who 
were enrolled before the IA is completed will continue the originally assigned treatment arm if 
they have received at least 1 treatment and the dose is considered safe.
Follow-Up Period:
After completion of the double-blind treatment period or early discontinuation from the study, all 
subjects will continued to be followed for an additional 6 week safety follow-up period. There 
will be two post treatment Follow-Up visits at Week 15 (or 3 weeks after early discontinuation)
and Week 18 (or 6 weeks after early discontinuation). Study procedures will occur as specified in 
Table 5.1-2.
The study design schematic is presented in Figure 3.1-1.

Study Design Schematic
The approximate duration of the study is up to a 5-week screening period (35 days), a 12-week 
double-blind treatment period (84 days), and 6 weeks of follow up (42 days), for a total of up to 
23 weeks (161 days).
The start of the trial is defined as the date of the first Screening Visit for the first subject 
screened. The end of the trial is defined as the date of the last visit or scheduled procedure shown 
in the Time & Events schedule for the last subject. Study completion is defined as the final date 
when the data from the last safety follow-up visit for the last subject has been received at BMS 
and the study is considered clinically complete.
3.2
Post Study Access to Therapy
At the end of the study, BMS will not continue to provide BMS supplied study drug to 
subjects/investigators unless BMS chooses to extend the study. The investigator should ensure 
that the subject receives appropriate standard of care to treat the condition under study. Pending 
appropriate preclinical and clinical data to support further drug development, BMS may 
authorize a study extension, or another mechanism to provide study drug to subjects who 
received clinical benefit in this study at the discretion of BMS. BMS reserves the right to 
terminate access to BMS supplied study drug if any of the following occur: a) the marketing 
application is rejected by responsible health authority; b) the study is terminated due to safety 
concerns; c) the subject can obtain medication from a government sponsored or private health 
program; d) BMS terminates development of the drug; or e) therapeutic alternatives become 
available in the local market.

3.3.3
Women of Childbearing Potential
A woman of childbearing potential (WOCBP) is defined as any female who has experienced 
menarche and who has not undergone surgical sterilization (hysterectomy or bilateral 
oophorectomy) and is not postmenopausal. Menopause 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 > 40mIU/mL to confirm menopause.
*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. The duration of 
the washout period below are suggested guidelines and the investigators should use their 
judgement in checking serum FSH levels. If the serum FSH level is > 40 mIU/ml at any time 
during the washout period, the woman can be considered postmenopausal:

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.

Hormonal Contraceptives:
The use of hormonal contraceptives (oral, via implant/depot or via eluting IUD) are prohibited as 
a method of highly effective contraception due to safety concerns from transient liver function 
test elevations observed in the drug-drug interactions study (IM006032) with BMS-986142 and a 
combination oral contraceptive (ethinyl estradiol and the norethindrone acetate). In the study, a 
total of 10 of 16 subjects that were dosed with the oral contraceptive and BMS-986142 in 
combination had mild to moderate elevations of transaminases without an associated increase of 
total bilirubin. The majority of ALT elevations were < 3xULN. The maximum increase occurred 
in one subject with an ALT 5.8x ULN without accompanying total bilirubin elevation. Most 
subjects had no symptoms, however, 3 subjects had nausea, 2 subjects had vomiting and 1 had 
chills. All of the elevated transaminase levels returned to baseline. An evaluation of the cause of 
the transaminase elevation is ongoing, but no marked changes in the exposures of BMS-986142 
or the components of the oral contraceptive were observed in a preliminary assessment of the 
data (i.e. no pharmacokinetic drug-drug interaction occurred during co-administration).
In addition, the use of oral or implantable estrogen-based hormone replacement therapy is also 
prohibited until additional drug interaction data becomes available. See Section 3.4.1.3.

Infections
Subjects who develop significant infectious complications during the study should be treated 
appropriately and have study medication withheld and restarted only when the infection is 
clinically resolved and the investigator considers it appropriate.
3.5
Discontinuation of Subjects Following Treatment with Study Drug
Subjects MUST discontinue investigational product (and non-investigational product at the 
discretion of the investigator) for any of the following reasons:

Subject’s request to stop study treatment or withdrawal of informed consent

Any clinical adverse event (AE), laboratory abnormality or intercurrent illness which, in the 
opinion of the investigator, indicates that continued participation in the study is not in the 
best interest of the subject

Termination of the study by Bristol-Myers Squibb (BMS)

Loss of ability to freely provide consent through imprisonment or involuntarily incarceration 
for treatment of either a psychiatric or physical (eg, infectious disease) illness

Unblinding a subject for any reason (emergency or non-emergency)

Use of prohibited medication

Development of new active manifestations of pSS requiring treatment with any non-protocol 
approved medications during the study

Inability or subject's failure to comply with the protocol requirements

Pregnancy

Male subjects must discontinue treatment if their female partners become pregnant during the 
trial. After discontinuation, male subjects are required to continue using a highly effective 
method of contraception for a total of 35 days post-treatment completion

Severe (eg, Grade 3), drug-related AEs of infection, bleeding events/coagulopathy, or 
injection site reactions


ANC < 500/mm3, confirmed by repeat

Potential drug induced liver injury (see Section 6.6 for definition)
In the case of pregnancy, the investigator must immediately notify the BMS Medical 
Monitor/designee of this event. In most cases, the study drug will be permanently discontinued in 
an appropriate manner (eg, dose tapering if necessary for subject safety). Please call the BMS 
Medical Monitor/designee within 24 hours of awareness of the pregnancy. If the investigator 
determines a possible favorable benefit/risk ratio that warrants continuation of study drug, a 
discussion between the investigator and the BMS Medical Monitor/designee must occur.
All subjects who discontinue study drug should comply with protocol specified follow-up 
procedures as outlined in Section 5. The only exception to this requirement is when a subject 
withdraws consent for all study procedures including post-treatment 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).
If study drug is discontinued prior to the subject’s completion of the study, the reason for the 
discontinuation must be documented in the subject’s medical records and entered on the 
appropriate case report form (CRF) page.
3.6
Post Study Drug Follow up
In this study, ESSDAI and ESSPRI as well as other efficacy measures at Week 12 are key 
endpoints of the study. Post study follow-up is of critical importance and is essential to 
preserving subject safety and the integrity of the study. Subjects who discontinue study drug
must continue to be followed for collection of outcome and/or survival follow-up data as 
required and in line with Section 5 until death or the conclusion of the study subject’s 
participation in the specified follow up period of the study, whichever comes first.
3.6.1
Withdrawal of Consent
Subjects who request to discontinue study drug will remain in the study and must continue to be 
followed for protocol specified follow-up procedures. The only exception to this is when a 
subject specifically withdraws consent for any further contact with him/her or persons previously 
authorized by subject to provide this information. Subjects should notify the investigator of the 
decision to withdraw consent from future follow-up in writing, whenever possible. The 
withdrawal of consent should be explained in detail in the medical records by the investigator, as 
to whether the withdrawal is from further treatment with study drug only or also from study 
procedures and/or post treatment study follow-up, and entered on the appropriate CRF page. In 
the event that vital status (whether the subject is alive or dead) is being measured, publicly 
available information should be used to determine vital status only as appropriately directed in 
accordance with local law.
3.6.2
Lost to Follow-Up
All reasonable efforts must be made to locate subjects to determine and report their ongoing 
status. This includes follow-up with persons authorized by the subject as noted above. Lost to

follow-up is defined by the inability to reach the subject after a minimum of three documented 
phone calls, faxes, or emails as well as lack of response by subject to one 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 the 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.

Investigational Product
An investigational product, also known as investigational medicinal product in some regions, is 
defined a pharmaceutical form of an active substance or placebo being tested or used as a 
reference in a clinical study, including products already with a marketing authorization but used 
or assembled (formulated or packaged) differently than the authorized form, or used for an 
unauthorized indication, or when used to gain further information about the authorized form.
The investigational product should be stored in a secure area according to local regulations. It is 
the responsibility of the investigator to ensure that investigational product is only dispensed to 
study subjects. The investigational product must be dispensed only from official study sites by 
authorized personnel according to local regulations.
In this protocol, investigational products (also described in Table 4-1) are: 

BMS-931699/lulizumab injection (12.5mg/vial, 12.5mg/mL) for subcutaneous administration

BMS-986142 50mg tablet (round) for oral administration


regarding the quality or appearance of the study drug arise, the study drug should not be 
dispensed and contact BMS immediately.
Study drug not supplied by BMS will be stored in accordance with the package insert.
Please refer to Section 9.2.2 for guidance on IP records and documentation and Section 4.8 for 
return and destruction instructions.
Investigational product documentation (whether supplied by BMS or not) must be maintained 
that includes all processes required to ensure drug is accurately administered. This includes 
documentation of drug storage, administration and, as applicable, storage temperatures, 
reconstitution, and use of required processes (eg, required diluents, administration sets).
Please refer to the current versions of the IBs and/or pharmacy reference sheets for complete 
storage, handling, dispensing information for BMS-931699/lulizumab and BMS-986142.
Lulizumab:
Preparation for Subcutaneous (SC) Use for BMS-931699/lulizumab
For SC dosing, no dilution of drug product solution (12.5 mg/mL) will be required for the 
12.5 mg dose. A commercially available appropriately sized sterile needle and appropriate 
syringe should be used for withdrawal from vial and administration (refer to the pharmacy 
dosing manual for further details on the subcutaneous preparation and administration for 
materials and instructions, which is provided separately).
The placebo for lulizumab injection is normal saline injection, which is administered in a similar 
fashion as described for the lulizumab injection. The normal saline to use as placebo will not be 
provided by the Sponsor. 
Lulizumab injection should be stored at 2 – 8 °C with protection from light and protection from 
freezing. After withdrawal into an appropriate sized syringe, the product must be administered 
within 4 hours. If not dosed immediately, filled syringes should be kept at 2 – 8 °C with 
protection from light and freezing prior to use.
Study personnel will administer the dose to the subject. The primary point of injection should be 
one of the upper arms; however, other points of injections are acceptable, such as stomach or 
thighs. The same injection site should not be used for consecutive study drug administration. The 
subjects should be monitored for at least 1 hour after each injection for potential reactions.
BMS-986142:
BMS-986142 bottles should be stored at 2 – 8 °C and stored in a tightly closed container. 
Please refer to the current version of the IB and/or pharmacy dosing manual for complete 
storage, handling and dispensing information for lulizumab and BMS-986142.

Interactive Voice Response System (IVRS or IWRS) designated by BMS for assignment of a 
5 digit subject number that will be unique across all sites. Enrolled subjects, including those not 
dosed, will be assigned unique sequential subject numbers by the IVRS/IWRS system starting 
with 00001, 00002, 00003, etc. for identification throughout the study. This subject number must 
not be reused for any other participant in the study.
After completion of all screening evaluations, on Day 1, all eligible subjects will be randomly 
assigned to 1 of 3 treatment arms (lulizumab, BMS-986142, or placebo) in an equal ratio. To 
randomize a subject, a phone call will be placed into the randomization option of the 
IVRS/IWRS in order to obtain a subject’s randomized treatment assignment. Randomization will 
be assigned in the order in which subjects qualify for treatment, not in the order of study 
enrollment. The IVRS will be available 24 hours a day, 7 days a week, via a toll-free number
(or via the internet for IWRS). Randomization will be stratified by hydroxychloroquine 
(Plaquenil) and oral corticosteroid use.
Specific instructions (including an enrollment/randomization worksheet) for the central 
enrollment and randomization procedure using an IVRS/IWRS will be provided to the site.
Randomized schedules will be generated and kept by the Randomization Group within Drug 
Supply Management of Bristol-Myers Squibb.
At all study visits when study drug is dispensed, each subject will be assigned specific container 
numbers by the IVRS/IWRS. Container numbers will be assigned non-sequentially and will 
correspond to the numbers printed on the containers and bottles containing study drug, and will 
be recorded on the appropriate eCRF.
4.5
Selection and Timing of Dose for Each Subject
All drug dosing should occur after all study-related assessments, including blood draws, 
are completed. Refer to Section 5.3 for additional information on the order of procedures.
After randomization, study drug will be dispensed according to the assignment by the 
IVRS/IWRS system. Study drugs are blinded and will be supplied in bottles for BMS-986142 
and its matching placebo for home administration. Doses of lulizumab or matching placebo are 
to be administered subcutaneously in the clinic or by a health care professional (eg, visiting 
nurse) in the home if approved by local IRB/EC and the investigator. Doses of BMS-986142 at 
350 mg or matching placebo are to be administered orally q24h (one time/day) with water and 
may be taken with or without food. Three tablets, one tablet from Bottle A and two tablets from 
Bottle B, will be taken all at the same time, once/day every day. Subjects should be instructed to 
bring their oral study drug (BMS-986142 or placebo) to be taken at the investigational site at 
every scheduled visit (eg, weekly if home visits are not performed) to avoid confusion about the 
timing of dose administration, given the frequency of PK assessments and study procedures 
during the study. On Day 1 and at Weeks 2, 4, 6, 8, and 10, study drug will be administered in 
the morning at the study site and after blood samples have been collected and questionnaires 
have been completed. For subjects who are on a stable dose of HCQ, subjects must also bring 
their HCQ dose to the site on Day 1, Day 8, Week 2 (Day 15), Week 4 (Day 29) and Week 12 
(Day 85) of the study as well as the two follow up visits at Week 15 (Day 106) and Week 18

(Day 127), as the HCQ dose will be administered at the same time as the study drugs in the 
morning at the study site to enable pre-dose PK samples to be taken. Two post-dose PK samples 
(2 and 4 hours after dosing) for HCQ and study drugs will also be collected at the Day 8 visit. 
However, at other visits, drug should be taken at approximately the same time each day.
For BMS-986142 and matching placebo, each subject will be dispensed a set of two (2) bottles 
every two weeks during treatment. Bottle A contains 17 tablets and Bottle B contains 34 tablets 
of blinded study drug. The 3 additional tablets in Bottle A and the additional 6 tablets in Bottle B
allow for a +/- 3 day window between each visit in the double-blind phase of the study. All study 
drug bottles (empty or full) that were dispensed to the subject must be brought back to the study 
site by the subject at Weeks 1, 2, 4, 6, 8, 10, and 12 during the double-blind period for drug 
reconciliation/compliance assessments.
4.6
Blinding/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 
investigational product 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, that it will alter the subject's immediate 
management. In many cases, particularly when the emergency is clearly not related to the 
investigational product, the problem may be properly managed by assuming that the subject is 
receiving one of the active products. It is highly desirable that the decision to unblind treatment 
assignment be discussed with the BMS 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.
For this study, the method of unblinding for emergency purposes is IVRS/IWRS. For 
information on how to un-blind in an emergency, consult the IVRS/IWRS manual.
In cases of any accidental unblinding, contact the BMS Medical Monitor and ensure every 
attempt is made to preserve the blind.
Any request to unblind a subject for non-emergency purposes should be discussed with the BMS 
Medical Monitor.
In case of an emergency, the Investigator(s) has unrestricted access to randomization information 
via the Interactive Voice Response System (IVRS/IWRS) and is capable of breaking the blind 
through the IVRS/IWRS system without prior approval from sponsor. Following the unblinding,
the Investigator should notify the BMS Medical Monitor.
The Bioanalytical Sciences section or its designate will be unblinded to the randomized 
treatment assignments in order to minimize unnecessary analysis of samples from control group 
subjects.

Interim Analysis:
The interim analysis will be conducted in a fully blinded manner such that treatment group 
assignments of study subjects are not known and are not used in any manner in the analysis.
4.7
Treatment Compliance
The investigator or designated study personnel will maintain a drug accountability log of all 
study drug(s) received, dispensed, destroyed and the amount returned to the Sponsor or supply 
depot. The drug supplies will be inventoried and accounted for throughout the study. The drug 
accountability log will be reviewed by the study monitor during site visits and at the completion 
of the study.
Study drug lulizumab or placebo will be administered via SC injection in the clinical facility. 
The treatment compliance in this study for lulizumab will be done at the study site where 
documentation of injection and compliance will be maintained.
Study drug BMS-986142 or placebo will be administered orally at home by the subjects or on 
site during clinic visits. The treatment compliance in this study for BMS-986142 will be 
determined by counts of returned tablets of study drug and information providing by questioning 
the subject.
4.8
Destruction of Study Drug
For this study, study drugs (those supplied by BMS or sourced by the investigator) such as 
partially used study drug containers, vials, and syringes may be destroyed on site.
If...
Then...
IP supplied by BMS (including its vendors)
Any unused IP supplied by BMS can only be destroyed 
after being inspected and reconciled by the responsible 
Study Monitor unless IP containers must be 
immediately destroyed as required for safety, or to 
meet local regulations (eg, cytotoxics or biologics).
If IP will be returned, the return will be arranged by the 
responsible Study Monitor.
IP sourced by site, not supplied by BMS (or its 
vendors) (examples include IP sourced from the sites 
stock or commercial supply, or a specialty pharmacy)
It is the investigator’s or designee’s responsibility to 
dispose of all containers according to the institutional 
guidelines and procedures.
It is the investigator’s or designee’s responsibility to arrange for disposal, provided that 
procedures for proper disposal have been established according to applicable federal, state, local, 
and institutional guidelines and procedures, and provided that appropriate records of disposal are 
kept. The following minimal standards must be met:

On-site disposal practices must not expose humans to risks from the drug.

On-site disposal practices and procedures are in agreement with applicable laws and 
regulations, including any special requirements for controlled or hazardous substances.

5.1.1
Retesting During Screening or Lead-in Period
Retesting of laboratory parameters and/or other assessments within any single Screening or 
Lead-in period will be permitted (in addition to any parameters that require a confirmatory 
value).
Any new result will override the previous result (ie, the most current result prior to 
Randomization) and is the value by which study inclusion will be assessed, as it represents the 
subject’s most current, clinical state.
Laboratory parameters and/or assessments that are included in Table 5.1-1, Screening Procedural 
Outline may be repeated in an effort to find all possible well-qualified subjects. Consultation 
with the BMS Medical Monitor may be needed to identify whether repeat testing of any
particular parameter is clinically relevant.
5.2
Study Materials
The site will provide all required materials for the tests performed locally (ie, relevant clinical 
laboratory tests). The site will have available a well-calibrated scale(s) and/or balance(s) for 
recording body weight and weight of the pre- and post-salivary flow collection tubes and 
moistened gauze (if using), a 12-lead ECG machine, and a calibrated sphygmomanometer and 
thermometer for vital signs assessments. The site will have urine collection containers, a 
refrigerated centrifuge, a heating block, a monitored and alarmed refrigerator, and freezer (-20°C 
or below), as well as containers and dry ice for shipment and storage of blood and urine samples. 
The site will provide all materials required for accurate source documentation of study activities.
Subjects will be provided with cooler bags and gel packs for transporting BMS-986142/matched 
placebo as it needs to be kept refrigerated.
BMS will provide a BMS-approved protocol and any amendments or administrative letters 
(if required), and IBs. Case report forms (electronic or hard copy) will be provided by BMS. 
Ten centimeter rulers will be provided by BMS for measurement of the Physician and Subject’s 
Global Assessment of disease activity on the Case Report Form.
All Investigator sites within this study will use an Electronic Data Capture (EDC) tool to submit 
study data to BMS. Electronic Case Report Forms (eCRFs) will be prepared for all data 
collection fields at Investigator sites, except for fields specific to Pregnancy Forms. Pregnancy 
Forms will be submitted to BMS using paper CRFs. Subject ESSPRI, Subject Global 
Assessment of disease activity worksheet, sicca symptoms NRS scales, fatigue, sexual function, 
and quality of life questionnaires will be completed by the subject and the information will then 
be entered with the EDC tool by the investigational site staff. ESSDAI and Physician Global 
Assessment of disease activity worksheet will be completed by the investigator and will then be 
entered with the EDC tool. Subject completed scales and questionnaires will be retained at the 
investigational site.  Examples of the worksheets, scales and questionnaires that BMS will 
provide are included in Appendices 3 - 13, however the country specific translations may include 
slight customizations as per local requirements (eg, removal of the BMS logo).  Translation 
certificates are available upon request.

5.3
Safety Assessments
All subjects who receive at least one dose of study medication will be evaluated for safety 
parameters. Additionally, any occurrence of an SAE from the time of consent until 42 days 
post-discontinuation of study drug dosing will be documented. Any occurrence of non-serious 
AEs will be collected from first dose of study drug until 42 days post discontinuation of dosing.
Safety assessments include the following:

Adverse Events

Safety laboratory tests

Physical examination

Vital signs

ECGs
On Day 1, the results of all assessments must be reviewed to assure that eligibility requirements 
are met before contacting the Central Randomization System for the subject’s randomization 
assignment. All assessments should be performed or administered prior to study drug 
administration unless otherwise indicated. Furthermore, patient scales, questionnaires and 
disease activity assessments (ie, ESSPRI, fatigue, quality of life and VAS/NRS scales) must be 
performed prior to all other assessments. Every effort must be made to ensure the same evaluator 
will complete the assessments for each subject at all visits.
After completion of patient scales, questionnaires and disease activity assessments, vital signs 
collection (blood pressure, heart rate, respiration rate, temperature), physical exams (when 
applicable), ECGs (when applicable), salivary flow assessments (when applicable), safety 
laboratory assessments, and pre-dose PK and laboratory biomarker assessments will occur before
the first dose of study medication is given from the assigned kit. At subsequent visits, this same 
order of assessments should be followed prior to the administration of the dose of assigned study 
drug. Subjects will be observed at the site for a minimum of 2 hours after receiving their first 
dose of study medication (tablet and injections) on Day 1. The observation period should be 
extended if clinically indicated. At subsequent visits subjects should be observed for 1 hour post-
injection.
Subjects who discontinue from the double-blind treatment period should have “End of Treatment 
Visit” procedures performed and should return to the clinical for the “Follow-Up Visits” 
approximately 21 and 42 days after the “End of Treatment Visit”. All procedures required for 
these visits should be completed as well as collection of concomitant medication information.
Only data for the procedures and assessments specified in this protocol should be submitted to 
BMS on a case report form. Additional procedures and assessments may be performed as part of

your institutional or medical practice standard of care; however, data for these assessments 
should remain in the subject’s medical record and should not be provided to BMS, unless 
specifically requested from the sponsor.
Safety assessments will be based on medical review of adverse event reports and the results of 
vital sign measurements, ECGs, physical examinations, and clinical laboratory tests. The severity 
of observed adverse events will be graded by National Cancer Institute’s Common Terminology 
Criteria for Adverse Events (NCI CTCAE) version 4.03. The incidence of observed adverse 
events will be tabulated and reviewed for potential significance and clinical importance.
Ongoing assessment of safety will be performed by an independent Data Monitoring Committee 
(DMC). The DMC may make recommendations to the Sponsor regarding conduct of the study 
based on safety observations.

Results of all laboratory tests required by this protocol must be provided to BMS, either recorded 
on the laboratory pages of the CRF or by another mechanism as agreed upon between the 
investigator and BMS (eg, provided electronically). If the units of a test result differ from those 
printed on the CRF, the recorded laboratory values must specify the correct units. Any abnormal 
laboratory test result considered clinically significant by the investigator must be recorded on the 
appropriate AE page of the CRF (see Section 6.1.1).
5.3.3
Tuberculosis Screening
A chest x-ray (CXR) and physical examination (PE) are considered part of the process to assess a 
subject’s eligibility as outlined in Section 3.3.2.
CXR at the screening visit is required if not already performed within 6 months of obtaining 
written informed consent or if documentation of the X-ray result is not on file.
In addition to a complete physical examination and medical history to evaluate exposure to 
tuberculosis, all subjects will have a screening test, an interferon gamma release assay [(IGRA) 
eg, QuantiFERON TB Gold®], preferably performed centrally. T-Spot® testing (if available)

may be used as a reflex test in the event of an indeterminate result of the QuantiFERON TB 
Gold® test. If unable to obtain central lab results (eg, repeated test due to indeterminate result), 
an IGRA test could be obtained locally, after consultation with the BMS Medical Monitor.
Indeterminate tests may be repeated once in an effort to obtain a definitive negative or positive 
result. If two indeterminate tests are recorded subject should be excluded from study 
participation.
Subjects with a positive screening test will not be eligible for the study unless they can provide 
documentation of completion of approved treatment for latent TB prior to dosing of study drug, 
and the subject has a negative chest X-ray done at screening that reveals no evidence of 
active TB.
5.3.4
Physical Exams
A complete medical history and physical exam will be obtained at the screening visit.
Complete and/or targeted/interim physical examinations may be performed by a Doctor of 
Medicine (MD), Doctor of Osteopathy (DO), Physician’s Assistant (PA), or Nurse Practitioner 
(NP). While the targeted/interim physical examination may not be as comprehensive as the initial 
full examination, key aspects of the targeted/interim examination should evaluate important body 
systems as clinically indicated. These body systems include at a minimum, the heart, lungs, 
abdomen, lymph nodes and skin. Evaluation of liver, spleen, breast and other body systems is at 
the discretion of the examiner. A targeted/interim physical examination may note any changes in 
the subject’s condition (body systems) since the last assessment and does not preclude 
examination of any of the body systems as clinically indicated.
Every effort should be made to ensure the same evaluator will complete the physical examination 
for each subject at specified visits throughout the study. Documentation of who performed the 
examination is to be recorded in source notes.
5.3.5
Electrocardiograms
A standard 12-lead ECG will be recorded at the times noted in the Time and Events Table 5.1-1
and Table 5.1-2.
5.4
Efficacy Assessments
All assessments should be performed prior to dosing.
5.4.1
Primary Efficacy Assessment
The primary efficacy endpoint is change from baseline ESSDAI score at Week 12. The EULAR 
Sjögren’s Syndrome Disease Activity Index (ESSDAI) is a systemic disease activity index that 
was designed to measure disease activity in subjects with pSS (see Appendix 3).63 The ESSDAI 
is now frequently used as a primary endpoint to measure disease activity in clinical studies. BMS 
will provide the appropriate versions of the assessment scale for use by the site. Sites should only 
use the versions of the scale provided by BMS for this study. Investigators should assess the 
ESSDAI parameters as described by Seror et al.64 The ESSDAI will be completed at the visits 
noted in the Time and Events Table 5.1-1 and Table 5.1-2. Results from each assessment will be

Secondary Efficacy Assessments
5.4.2.1
Ophthalmologic Assessments
The following procedures should be performed at baseline/Day 1, Week 4, Week 8, and Week 12
by an ophthalmologist or optometrist experienced in the diagnosis and treatment of Sjögren’s 
syndrome subjects and according to the methods described in Whitcher, et al.65 A visit window 
of 5 days to perform the ophthalmologic assessments is acceptable (baseline/Day 1 assessment 
can be performed up to 5 days prior to dosing only), but all assessments must be performed 
during the same visit. The use of alternative ocular dyes may be permitted per local standards 
and/or regulations, and after consultation with the BMS Medical Monitor.

Schirmer’s test: The test (without anaesthesia) is performed by placing a narrow calibrated 
filter-paper strip in the inferior cul-de-sac of each eye. Aqueous tear production is measured 
by the length in millimeters that the strip wets during the 5 minute test period

Tear break-up time (TBUT): Determined by instilling fluorescein dye and evaluating the 
stability of the pre-corneal tear film. After several blinks, the tear film is examined using a 
broad beam of the slit-lamp (biomicroscope) with a cobalt blue filter. The TBUT, defined as 
the time in seconds between the subjects’s last blink and the first appearance of a random dry 
spot on the corneal surface, is measured 3 times and the mean value is recorded

Ocular surface staining: The test is performed by instillation of fluorescein dye and either 
lissamine green or Rose bengal dye to stain the cornea and conjunctiva, respectively. After 
instilling the dye, the ocular surface is examined through a slit lamp (biomicroscope) the 
staining pattern is recorded per the method described in Whitcher, et al65
The results from each of the above procedures will be recorded in site source records as well as 
entered into the corresponding eCRF provided by BMS or designee.
5.4.2.2
Salivary Flow
Whole unstimulated and stimulated salivary flow will be assessed at Screening (unstimulated 
only), baseline/Day 1, Week 4, Week 8, and Week 12. Subjects should refrain from eating or 
drinking for at least 90 minutes prior to the test procedures. Any saliva collected should be 
transferred to the appropriate container containing protease inhibitor cocktail, including notation 
as to whether it is a stimulated or unstimulated sample, for saliva biomarker assessments on 
Days 1, 29, 57 and 85 (see Section 5.6). Stimulated and unstimulated samples must not be 
combined or pooled into a single collection container.

Unstimulated salivary flow: Subjects should sit quietly, without talking or chewing, and spit 
any saliva that accumulates in the floor of the mouth during a period of 5 minutes into a 
pre-weighed tube

Stimulated whole salivary flow: Subjects should chew on a piece of paraffin (wax) or (sites 
accustomed to using pre-weighed, moistened gauze as the stimulant may continue to use this

Clinical Assessor Requirements
The ESSDAI, and the Physicians Global Assessment of Disease Activity (phyGDA) can be 
performed by the investigator or sub-investigator. The sub-investigator may be a Doctor of 
Medicine (MD) or Doctor of Osteopathy (DO), Physician’s Assistant (PA) or Nurse Practitioner 
(NP). The below requirements also pertain to the ophthalmologic procedures (refer to 
Section 5.4.2).
For each assessment: 1) Every effort should be made to ensure the same assessor is used for a 
given subject throughout the study, and 2) The clinical assessor cannot be unblinded to study 
medication assignment or the subject.
Visits should be scheduled with the availability of the assessor taken into account. If the assessor 
is unable to complete the evaluation, then another qualified individual can take the place of the 
initial evaluator, as long as the restrictions, described above, are still met and all efforts are made 
to assure consistency between subject evaluations.
5.5
Pharmacokinetic Assessments
Pharmacokinetics of lulizumab and BMS-986142 will be derived from plasma/serum 
concentration versus time. The pharmacokinetic parameters to be assessed include Ctrough 
(ng/mL).

validated LC-MS/MS assay. The plasma samples from subjects dosed with BMS-986142 will be 
analyzed for BMS-986142 by a validated LC-MS/MS assay. 
Pharmacokinetic samples collected from a subject who received placebo only for both drugs will 
not be analyzed. In addition, serum or plasma samples will be archived for potential exposure 
biomarker response analysis, if the need arises and to the extent possible.
Individual subject PK parameter values will be derived by non-compartmental methods by a 
validated PK analysis program. Actual times will be used for the analyses.
Table 5.5-1 lists the sampling schedule to be followed for the assessment of PK for subjects who 
are not on hydroxychloroquine (HCQ, Plaquenil). Further details of blood collection and 
processing will be provided to the site in the procedure manual.
On Day 1 and Day 8, it is important that the SC dose and oral dose are given to the subjects at 
the same time to make sure the PK samples are taken at the planned hours relative to dosing.

For each PK blood draw, one tube for serum sample and one tube for plasma sample will be 
taken.
Table 5.5-2 lists the sampling schedule to be followed for the assessment of PK for subjects who 
are on a stable dose of hydroxychloroquine (HCQ, Plaquenil). Serial blood PK samples of 
HCQ will be taken during Screening (subjects taking HCQ who have met all entry criteria must 
return for Screening Visit #2 for this collection), on Day 8 and Day 29 in addition to lulizumab 
and BMS-986142 blood PK samples. 
For sampling time points that only lulizumab and BMS-986142 PK samples are collected, one 
tube for serum sample and one tube for plasma sample will be taken.
For sampling time points that both lulizumab/BMS-986142 and HCQ PK samples are collected, 
one tube for serum sample, one tube for plasma sample and one tube for HCQ whole blood 
sample will be taken. Except for the 2 and 4 hours samples on Day 8, only one plasma tube 
sample for BMS-986142 and one whole blood tube for HCQ will be taken.
Trough level HCQ blood PK samples will be taken on Day 1, Day 15, Day 29, Day 85 and at the 
two follow-up visits on Days 106 and 127 (Table 5.5-2). Subjects should bring their daily dose of 
HCQ to the clinical site on these days to be administered at the site.
On Day 8, it is important that the dosing of study drug (a SC injection and an oral dose) and the 
HCQ are given to the subjects at the same time to make sure the PK samples are taken at the 
planned hours relative to dosing. 
Pharmacokinetics of HCQ will be derived from whole blood concentration versus time. The

Additional Research
This protocol will include residual sample storage for additional research (AR).
For All US sites:
Additional research is required for all study participants, except where prohibited by IRBs/ethics 
committees, or academic/institutional requirements. Where one or more of these exceptions 
occurs, participation in the additional research should be encouraged but will not be a condition 
of overall study participation. 

If the IRB/ethics committees and site agree to the mandatory additional research retention 
and/or collection, then the study participant must agree to the mandatory additional research 
as a requirement for inclusion in the study.

If optional participation is permitted and approved, then the study participants may opt out of 
the additional research retention and/or collection.
For non-US Sites:
Additional research is optional for all study participants, except where retention and/or collection 
is prohibited by local laws or regulations, ethics committees, or institutional requirements. 
This collection for additional research is intended to expand the translational R&D capability at 
Bristol-Myers Squibb, and will support as yet undefined research aims that will advance our 
understanding of disease and options for treatment. It may also be used to support health

authority requests for analysis, and advancement of pharmacodiagnostic development to better 
target drugs to the right patients.  This may also include genetic/genomic exploration aimed at 
exploring disease pathways, progression and response to treatment etc.
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.

Residual samples from biomarker, biopsy and PK sample collections (see Table 5.6.1-1) will 
also be retained for additional research purposes
Samples kept for future research will be stored at the BMS Biorepository in NJ, USA 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 fifteen 
(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.
Further details of sample collection and processing will be provided to the site in the procedure 
manual.

ADVERSE EVENTS
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 drug and that 
does not necessarily have a causal relationship with this treatment. An AE can therefore be any

unfavorable and unintended sign (such as an abnormal laboratory finding), symptom, or disease 
temporally associated with the use of study drug, whether or not considered related to the study 
drug. Severity of all adverse events will be graded by using the National Cancer Institute’s 
Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03.
The causal relationship to study drug is determined by a physician and should be used to assess 
all AEs. The causal relationship can be one of the following:
Related: There is a reasonable causal relationship between study drug administration and 
the AE.
Not related: There is not a reasonable causal relationship between study drug 
administration and the AE.
The term "reasonable causal relationship" means there is evidence to suggest a causal 
relationship.
Adverse events 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 one or more AEs).
Sponsor or designee will be reporting adverse events to regulatory authorities and ethics 
committees according to local applicable laws including European Directive 2001/20/EC and 
FDA Code of Federal Regulations 21 CFR Parts 312 and 320.
6.1
Serious Adverse Events
A Serious Adverse Event (SAE) is 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)

results in persistent or significant disability/incapacity

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.) Potential drug induced liver injury (DILI) is also considered an 
important medical event. (See Section 6.6 for the definition of potential DILI.)

Suspected transmission of an infectious agent (eg, pathogenic or nonpathogenic) via the study 
drug is an SAE.
Although pregnancy, overdose, cancer, and potential DILI are not always serious by regulatory 
definition, these events must be handled as SAEs (see Section 6.1.1 for reporting pregnancies).
Any component of a study endpoint that is considered related to study therapy (eg, death is an 
endpoint, if death occurred due to anaphylaxis, anaphylaxis must be reported) should be reported 
as SAE (see Section 6.1.1 for reporting details).
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)
6.1.1
Serious Adverse Event Collection and Reporting
Sections 5.6.1 and 5.6.2 in the Investigator Brochures (IBs) represent the Reference Safety 
Information to determine expectedness of serious adverse events for expedited reporting. 
Following the subject’s written consent to participate in the study, all SAEs, whether related or 
not related to study drug, must be collected, including those thought to be associated with 
protocol-specified procedures. All SAEs must be collected that occur during the screening period 
from the date of subject’s written consent until 42 days post discontinuation of dosing.
The investigator must report any SAE that occurs after these time periods and that is believed to 
be related to study drug or protocol-specified procedure.
An SAE report must be completed for any event where doubt exists regarding its seriousness.
If the investigator believes that an SAE is not related to study drug, but is potentially related to 
the conditions of the study (such as withdrawal of previous therapy or a complication of a study 
procedure), the relationship must be specified in the narrative section of the SAE Report Form.

SAEs, whether related or not related to study drug, and pregnancies must be reported to BMS 
(or designee) within 24 hours of awareness of the event. SAEs must be recorded on the SAE 
Report Form; pregnancies on a Pregnancy Surveillance Form (electronic or paper forms).
The preferred method for SAE data reporting collection is through the eCRF. The paper 
SAE/pregnancy surveillance forms are only intended as a back-up option when the eCRF system 
is not functioning. In this case, the paper forms are to be transmitted via email or confirmed 
facsimile (fax) transmission to:
SAE Email Address: Refer to Contact Information list.
SAE Facsimile Number: Refer to Contact Information list.
For studies capturing SAEs through electronic data capture (EDC), electronic submission is the 
required method for reporting. In the event the electronic system is unavailable for transmission, 
paper forms must be used and submitted immediately. When paper forms are used, the original 
paper forms are to remain on site.
SAE Telephone Contact (required for SAE and pregnancy reporting): Refer to Contact
Information list.
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.
BMS will be reporting adverse events to regulatory authorities and ethics committees according 
to local applicable laws including European Directive 2001/20/EC and FDA Code of Federal 
Regulations 21 CFR Parts 312 and 320. A SUSAR (Suspected, Unexpected Serious Adverse 
Reaction) is a subset of SAEs and will be reported to the appropriate regulatory authorities and 
investigators following local and global guidelines and requirements.
6.2
Nonserious Adverse Events
A nonserious adverse event is an AE not classified as serious.
6.2.1
Nonserious Adverse Event Collection and Reporting
The collection of nonserious AE information should begin at initiation of study drug. Nonserious 
AE information should also be collected from the start of a placebo lead-in period or other 
observational period intended to establish a baseline status for the subjects.
Nonserious AEs should be followed to resolution or stabilization, or reported as SAEs if they 
become serious (see Section 6.1.1). Follow-up is also required for nonserious AEs that cause 
interruption or discontinuation of study drug and for those present at the end of study treatment 
as appropriate. All identified nonserious AEs must be recorded and described on the nonserious 
AE page of the CRF (paper or electronic).

Completion of supplemental CRFs may be requested for AEs and/or laboratory abnormalities 
that are reported/identified during the course of the study.
6.3
Laboratory Test Result Abnormalities
The following laboratory test result abnormalities should be captured on the nonserious AE CRF 
page or SAE Report Form (electronic) as appropriate. Paper forms are only intended as a 
back-up when the electronic system is not functioning:

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 drug 
discontinued or interrupted

Any laboratory test result abnormality that required the subject to receive specific corrective 
therapy
It is expected that wherever possible, the clinical rather than laboratory term would be used by 
the reporting investigator (eg, anemia versus low hemoglobin value).
6.4
Pregnancy
If, following initiation of the study drug, it is subsequently discovered that a study subject is 
pregnant or may have been pregnant at the time of study exposure, including during at least 
5 half-lives after product administration (35 days for lulizumab), the investigator must 
immediately notify the BMS Medical Monitor (or 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 Section 6.1.1.
In most cases, the study drug will be permanently discontinued in an appropriate manner 
(eg, dose tapering if necessary for subject safety). Please call the BMS Medical Monitor or 
designee within 24 hours of awareness of the pregnancy.
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
subject.
Follow-up information regarding the course of the pregnancy, including perinatal and neonatal 
outcome and, where applicable, offspring information must be reported on the Pregnancy 
Surveillance Form.
Any pregnancy that occurs in a female partner of a male study participant should be reported to 
BMS. Information on this pregnancy will be collected on the Pregnancy Surveillance Form. In 
order for BMS to collect any pregnancy surveillance information from the female partner, the 
female partner must sign an informed consent form for disclosure of this information. 
Information on this pregnancy will be collected on the Pregnancy Surveillance Form.
6.5
Overdose
An overdose is defined as the accidental or intentional administration of any dose of a product 
that is considered both excessive and medically important. All occurrences of overdose must be 
reported as an SAE (see Section 6.1.1 for reporting details).

Potential Drug Induced Liver Injury (DILI)
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 6.1.1 for reporting details).
Potential drug induced liver injury is defined as:
1. AT (ALT or AST) elevation > 3 times upper limit of normal (ULN)
AND
2. Total bilirubin > 2 times ULN, without initial findings of cholestasis (elevated serum alkaline 
phosphatase)
AND
3. No other immediately apparent possible causes of AT elevation and hyperbilirubinemia, 
including, but not limited to, viral hepatitis, pre-existing chronic or acute liver disease, or the 
administration of other drug(s) known to be hepatotoxic

DATA MONITORING COMMITTEE AND OTHER EXTERNAL 
COMMITTEES
A Data Monitoring Committee (DMC) will monitor overall safety data regularly to ensure that 
the benefits and risks of study participation remain acceptable. Based on the regular reviews of 
emerging data, the DMC may recommend to the Sponsor alteration and/or termination of the 
trial or a treatment group, or cessation of further enrollment into a treatment group.
Data summaries and listings will be provided to the DMC to facilitate their safety assessment at 
the regularly scheduled times as well as on an ad hoc basis if needed. The DMC will review 
safety data including SAEs and events of special interest, focusing on early signal detection. 
Further details on the frequency, content, and methods of data reports to the DMC will be 
outlined in the Charter of that Committee along with the processes and procedures the committee 
will follow.

STATISTICAL CONSIDERATIONS
8.1
Sample Size Determination
The sample size calculation is based on the power to compare change from baseline in ESSDAI 
at Week 12 between active treatment arms (lulizumab or BMS-986142) and the placebo arm. 
With a two-sided two-sample t-test at significance level 0.05, data from 25 treated subjects per 
arm will provide approximately 90% power to detect a placebo-adjusted 3-point decrease from

baseline for each active treatment group, assuming common standard deviations of 3.2.66 In 
addition, the Hochberg’s step-up procedure will be used to adjust the multiplicity due to the 
comparison of two active treatment arms (lulizumab or BMS-986142) to the placebo arm. 
The primary efficacy analysis will be conducted on all randomized subjects who received at least 
one dose of study drug.
An interim analysis will be conducted after at least 30 subjects reach Week 12 (complete 
12 weeks of treatment) and complete the specified assessments for ESSDAI. The interim 
analysis will be conducted in a fully blinded manner such that treatment group assignments of 
study subjects are not known and are not used in any manner in the analysis. A blinded 
examination of the variance of the primary endpoint will be performed and compared to the 
assumption used in planning the study. If this comparison suggests the initial assumption was 
substantially too low, the total study sample size may be increased by up to 45 additional 
subjects (ie, to a maximum of 120 subjects in total) to maintain adequate study power.67,68,69
Regardless of the outcome from the blinded examination of variability, the study sample size 
will not be decreased. A maximum study sample size of 120 subjects in total, ie, 40 subjects per 
arm, can provide each active treatment arm 79% power to detect a placebo-adjusted 3-point 
decrease from baseline for common standard deviations as large as 4.8, using a two-sided 
two-sample t-test comparing each active treatment arm to placebo at significant level 0.05.

of two active treatments (lulizumab or BMS-986142) to the placebo arm in the primary endpoint 
(ie, change from baseline in ESSDAI at Week 12). The corresponding adjusted p-values for the 
Hochberg procedure will be provided.
8.4.2.2
Secondary Efficacy Analyses
For all secondary endpoints, no multiplicity adjustment will be applied, and nominal p-values 
may be provided if applicable. For each of the following categorical secondary endpoints, the 
estimate and its corresponding two-sided 95% confidence interval will be calculated for the 
proportion for each treatment arm. In addition, as exploratory analyses, differences of the 
proportions between each active treatment arm and the placebo arm will be evaluated and their 
corresponding two-sided 95% confidence intervals will be provided.

Interim Analyses
One interim analysis will be conducted when at least 30 subjects reach Week 12 (complete 
12 weeks of treatment) and complete the specified assessments for the Week 12 ESSDAI score.
The interim analysis will be conducted in a fully blinded manner such that treatment group 
assignments of study subjects are not known and are not used in any manner in the analysis.
Specifically, a blinded examination of the variance of the primary endpoint will be performed 
and compared to the assumption used in planning the study. If this comparison suggests the 
initial assumption is substantially too low, the total study sample size may be increased by up to 
45 additional subjects (ie, to a maximum of 120 subjects in total) to maintain adequate study 
power.67,68,69 Regardless of the outcome from the blinded examination of variability, the study

STUDY MANAGEMENT
9.1
Compliance
9.1.1
Compliance with the Protocol and Protocol Revisions
The investigator should not implement any deviation or change to the protocol without prior 
review and documented approval/favorable opinion of an amendment from the IRB/IEC (and if 
applicable, also by local health authority) except where necessary to eliminate an immediate 
hazard(s) to study subjects. If a deviation or change to a protocol is implemented to eliminate an 
immediate hazard(s) prior to obtaining relevant approval/favorable opinion(s), the deviation or 
change will be submitted as soon as possible to:

IRB/IEC 

Regulatory Authority(ies), if applicable by local regulations per national requirements)
Documentation of approval/favorable opinion signed by the chairperson or designee of the 
IRB(s)/IEC(s) and if applicable, also by local health authority, must be sent to BMS. If an 
amendment substantially alters the study design or increases the potential risk to the subject: (1) 
the consent form must be revised and submitted to the IRB(s)/IEC(s) for review and 
approval/favorable opinion; (2) the revised form must be used to obtain consent from subjects 
currently enrolled in the study if they are affected by the amendment; and (3) the new form must 
be used to obtain consent from new subjects prior to enrollment.
If the revision is done via an administrative letter, investigators must inform their IRB(s)/IEC(s).
9.1.2
Monitoring
BMS or designated representatives will review data centrally to identify potential issues to 
determine a schedule of on-site visits for targeted review of study records.
Representatives of BMS must be allowed to visit all study site locations periodically to assess the 
data quality and study integrity. On site they will review study records and directly compare 
them with source documents, discuss the conduct of the study with the investigator, and verify 
that the facilities remain acceptable. Certain CRF pages and/or electronic files may serve as the 
source documents: This includes the subject’s Global Assessment of Disease Activity, the 
Physician Global Assessment of Disease Activity, the PROMIS fatigue scale, the SF-36, and the 
WPAI.
In addition, the study may be evaluated by BMS internal auditors and government inspectors 
who must be allowed access to CRFs, source documents, other study files, and study facilities. 
BMS audit reports will be kept confidential.
The investigator must notify BMS promptly of any inspections scheduled by regulatory 
authorities, and promptly forward copies of inspection reports to BMS or designee.

Source Documentation
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 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.
9.1.3
Investigational Site Training
Bristol-Myers Squibb will provide quality investigational staff training prior to study initiation. 
Training topics will include but are not limited to: GCP, AE reporting, study details and 
procedure, electronic CRFs, study documentation, informed consent, and enrollment of WOCBP.

GLOSSARY OF TERMS
Term
Definition
Complete Abstinence
If one form of contraception is required, Complete Abstinence is defined 
as complete avoidance of heterosexual intercourse and is an acceptable 
form of contraception for all study drugs. Female subjects must continue 
to have pregnancy tests. Acceptable alternate methods of highly effective 
contraception must be discussed in the event that the subject chooses to 
forego complete abstinence.
If two forms of contraception is required, Complete abstinence is defined 
as complete avoidance of heterosexual intercourse and is an acceptable 
form of contraception for all study drugs. Subjects who choose complete 
abstinence are not required to use a second method of contraception, but 
female subjects must continue to have pregnancy tests. Acceptable 
alternate methods of highly effective contraception must be discussed in 
the event that the subject chooses to forego complete abstinence.
Expanded definition Complete abstinence as defined as complete 
avoidance of heterosexual intercourse is an acceptable form of 
contraception for all study drugs. This also means that abstinence is the 
preferred and usual lifestyle of the subject. This does not mean periodic 
abstinence (eg, calendar, ovulation, symptothermal, profession of 
abstinence for entry into a clinical trial, post-ovulation methods) and 
withdrawal, which are not acceptable methods of contraception. Subjects 
who choose complete abstinence are not required to use a second method 
of contraception, but female subjects must continue to have pregnancy 
tests. Acceptable alternate methods of highly effective contraception must 
be discussed in the event that the subject chooses to forego complete 
abstinence.

APPENDIX 1
METHODS OF CONTRACEPTION
At a minimum, subjects must agree to use one highly effective method of contraception (or one 
highly effective plus one less effective method, as per local country regulations) as listed below:
HIGHLY EFFECTIVE METHODS OF CONTRACEPTION
Highly effective methods of contraception have a failure rate of < 1% when used consistently 
and correctly. WOCBP and female partners of male subjects are expected to use one of the 
highly effective methods of contraception listed below. Male subjects must inform their female 
partners who are WOCBP of the contraceptive requirements of the protocol and are expected to 
adhere to using contraception with their partner.

Non-hormonal intrauterine devices (IUDs) such as ParaGard

Bilateral tubal occlusion

Vasectomised partner with documented azoospermia 90 days after procedure
