Brief summary:
Study evaluating the safety and efficacy of a novel biologic in the treatment of systemic lupus erythematosus in male and female adults. Patients who qualify will be randomized to either active BMS-931699 or placebo for initially, up to 24 weeks. Patients who complete the initial 24 weeks of treatment and who are responding to therapy will have the option to continue receiving BMS-931699 as part of a long-term extension (LTE). Disease activity and safety will be assessed over the course of the study through laboratory values, various rating scales accepted in systemic lupus erythematosus studies and patient self reporting.

Detailed description:
1. Subjects completing Day 169 (24 weeks) on study medication may be eligible to enter an optional LTE period
2. The LTE period will remain blinded but will no longer have a placebo arm:

   * Subjects will remain on their originally assigned treatment arm unless they were on placebo
   * Subjects initially randomized to placebo arm will be automatically re-randomized into one of the existing active arms at Day 169 (24 weeks)

SYNOPSIS
Clinical Protocol IM128027
Protocol Title: A Phase 2, Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the 
Safety and Efficacy of BMS-931699 vs Placebo on a Background of Limited Standard of Care in the Treatment of 
Subjects with Active Systemic Lupus Erythematosus
Investigational Product(s), Dose and Mode of Administration, Duration of Treatment with Investigational 
Product(s): BMS-931699 (active) or lulizumab pegol, administered subcutaneously, is formulated at 12.5 mg/mL 
and is provided as a liquid in single-use vials. Four treatments will be administered along with placebo treatment: 
12.5 mg weekly, 12.5 mg every other week (EOW), 5 mg EOW and 1.25mg EOW, on a background of limited 
standard of care medications. The dose levels may be modified based on the interim analysis results. The study will 
comprise a short-term period (Part 1 and Part 2) and a long-term extension (LTE) period. Treatment duration will be 
up to 24 weeks (169 days) in the short term period. Subjects completing the short term period on study medication 
may be eligible to enter the LTE period. At the time of writing there is no defined end date to the long-term 
extension period, however, the LTE provision may be further adjusted based on results from the ongoing lulizumab 
development program.
Study Phase: Phase 2
Research Hypothesis: BMS-931699 will have greater clinical efficacy compared to placebo on the British Isles 
Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) score, when added to stable 
background standard of care in subjects with active manifestations of systemic lupus erythematosus (SLE) 
including, at a minimum, elevated antinuclear antibodies, arthritis, and/or cutaneous manifestations satisfying the 
BILAG “A” or “B” criteria.
Objectives for the short-term period:
Primary Objective:
To compare the proportion of subjects who achieve BICLA response (BICLA response rate) at Day 169.
Secondary Objectives:

Study Design:
Phase 2, parallel-arm, randomized, double-blinded, multicenter, international study, with an adaptive design. Dose
arm(s) may be adapted based on results of the planned interim analyses from Part 1 and Part 2, as follows:

Safety and RO interim analysis: safety and RO analysis will be performed when approximately 6 to 10 subjects 
per arm have reached Study Day 29. Based on the results of this analysis, dose arms(s) may be adjusted or may
be dropped.

Interim analysis for futility and dose adaptation on BICLA response, SRI response, ACR28 and some SLE 
biomarkers (such as auto-antibodies, complement levels, etc.) with possible exploratory exposure response 
analysis, will be performed when approximately 30 subjects per arm (including subjects from Part 1 and Part 2) 
have reached Study Day 85 (12 weeks) of treatment or have discontinued prior to reaching study Day 85.
Analysis will be performed by an unblinded Sponsor team, while maintaining blind at the site and subject level. 
Based on the results, the dose levels and sample size may be modified. 

Ongoing assessment of safety will be performed by an independent Data Monitoring Committee (DMC) and an 
internal unblinded safety monitoring team. Both entities may make recommendations to the Sponsor regarding 
conduct of study and dose adjustment based on safety observations.

Overall study design
Part 1
• Limited to approximately 30 to 50 subjects (6-10 per arm).
• Interim analysis for safety and RO once 30-50 subjects have reached Day 29 (4 weeks).
• These subjects will continue study treatment beyond the interim analysis for safety and RO and 
will be treated for up to 24 weeks, and followed for 6 additional weeks after treatment is completed 
or discontinued. Treatment could be shorter if dose arm(s) are dropped. 
Intense safety monitoring by the 
DMC, in collaboration with an 
internal safety monitoring team, 
will be performed during Part 1 
and continue during Part 2.
DMC and unblinded internal 
safety monitoring activities will 
continue during long-term 
extension. 
Part 2
• Will start once cumulative safety profile is considered acceptable and RO data for 6-10 subjects 
per arm for >28 days are available and the interim analysis from Part 1 is completed. Results of the 
interim analysis in Part 1 and DMC reviews may result in treatment arm(s) modifications. 
• Each treatment arm will enroll approximately 70 subjects, including subjects from Part 1.
• Part 2 will have an interim analysis for futility once approximately 30 subjects per arm complete 
Day 85 (12 weeks), or have discontinued. As in the interim analysis from Part 1, results of the 
interim analysis in Part 2 and DMC reviews may result in treatment arm(s) modifications. 
• All subjects could be treated for up to 24 weeks and followed for 6 additional weeks after 
treatment is completed or discontinued. Treatment could be shorter if dose arm(s) are dropped. 
Long-Term Extension
• Subjects completing Day 169 (24 weeks) on study medication may be eligible to enter an optional 
long-term extension (LTE) period.
• The LTE period will remain blinded but will no longer have a placebo arm.
• Subjects will remain on their originally-assigned treatment arm unless they were on 
placebo. 
• Subjects initially randomized to placebo arm will be automatically re-randomized into one 
of the existing active arms at Day 169 (24 weeks).

Duration of Study:
Short-term Period: 28 days (4 weeks) of screening, 168 days (24 weeks) of treatment, 42 days (6 weeks) of safety 
follow-up, for a total of approximately 238 days (34 weeks). Subjects randomized into either Part 1 or Part 2 will be 
treated for up to 24 weeks and will have the same procedures performed and will follow the same visit schedule. If 
subject is eligible and opts to continue into LTE, the 42-day follow-up visit will not be performed after the 
short-term period is completed and subject will enter LTE directly.  If subject opts not to enter LTE then a follow-up 
visit will be completed 42 days after end of treatment. At the time of writing there is no defined end date to the 
long-term extension period, however, the LTE provision may be further adjusted based on results from the ongoing 
lulizumab development program. Subjects discontinuing treatment during the LTE period will complete the 
follow-up visit approximately 6 weeks after receiving their last dose of study medication.
Number of Subjects:
Approximately 450 subjects will need to be screened to randomize approximately 350 subjects. Utilizing a 
1:1:1:1:1 randomization scheme resulting in approximately 70 subjects in the each treatment arm. If the day 85
interim analysis suggests an additional dose arm at a lower dose level needs to be added, then up to 40 additional 
subjects may be randomized. 
Approximately 125 sites will participate in this study, which will be conducted globally and should include, but will 
not be limited to, participation of countries located in North America and Europe.
Study Population: Male and female subjects, ages 18-70 years inclusive, satisfying the SLE classification criteria 
of the American College of Rheumatology (1982), as revised by the College in 1997, with elevated titer of 
anti-nuclear antibodies at Screening, active features of SLE, including at least one adjudicated BILAG B or greater 
due to arthritis and/or inflammatory skin disease. Unless intolerant, subjects must be on background therapy for 
12 weeks, on a stable dose for at least 8 weeks, with at least one steroid sparing agent, including azathioprine 
(AZA), leflunomide, methotrexate (MTX), anti-malarial agents, mycophenolate mofetil/ mycophenolic acid, which 
must remain on stable dose throughout the study. Prednisone is not required; however, if subject is taking 
prednisone (or prednisone-equivalent), the maximum dose must not exceed 30mg/day of prednisone (or prednisone 
equivalent) at screening for a subject to be eligible and must be at a maximum of 10mg/day for at least 5 days prior 
to Day 1. Subjects must not have SLE manifestations or other disorders expected to require increase in 
corticosteroids (CS) during the study. 
Women of childbearing potential (WOCBP) must not be nursing or pregnant and must be using an acceptable 
method of contraception for at least 4 weeks before dosing. WOCBP must have a negative pregnancy test within 
24 hours prior to dosing with study medication

Statistical Considerations:
Sample Size: The sample size calculation is based on power to compare the proportion of subjects who achieve 
BICLA response (the BICLA response rate) at Day 169 between BMS-931699 and placebo arms. With a one-sided 
continuity corrected chi-squared test at significance level 0.05, data from 70 randomized and treated subjects per 
arm will provide at least 89% power to detect a 25% increase in the BICLA response rate in the active treatment 
arms (ie. 50% response rate in BMS active arms) compared to the placebo and provide 74% power to detect 20% 
increase in the BICLA response rate in the active treatment arm (ie, 45% response rate in BMS active arm) 
compared to the placebo, assuming that the placebo arm has 25% response rate which is reasonable based on the 
EMBLEM phase 2 trial result.1 No adjustment will be made for multiplicity. Subjects who discontinue 
treatment/study prior to Day 169 will contribute to the data that will be analyzed for BICLA response at Day 169 
(discontinuation will indicate no BICLA response). Therefore, no adjustment will be made for discontinuations.
The primary efficacy analysis will be conducted on all randomized patients who received at least one dose of the 
study drug. In order to get 70 randomized and treated subjects per arm, an adequate numbers of subjects need to 
meet the inclusion/exclusion criteria at screening.
If the interim analysis for futility and dose adaption suggests an additional dose arm at a lower dose level needs to be 
added, then up to 40 additional subjects may be randomized.

Interim analysis:
Interim Analysis for Safety/RO at Day 29
When at least 6 subjects per arm have reached Day 29, an interim analysis (IA) for safety and RO will be performed.
The safety analysis will focus on incidence and severity of all adverse events (AEs), serious AEs and pre-established 
Events of Special Interest such as infection AEs and any other safety analysis requested by DMC. For RO: the 
median RO at Day 29 for each treatment arm will be calculated. Based on the results of this interim analysis, a 
decision will be taken regarding the doses that will be carried forward into Part 2 of the study. Specifically, dosing 
regimens originally included in Part 1 may be discontinued and/or new dosing regimens may be added according to 
the following criteria:
Safety:
The DMC in conjunction with an unblinded internal monitoring team may require one or more doses to be 
discontinued if stopping criteria are met or other safety signals arise that the Medical Monitor and/or DMC consider 
of sufficient concern.
Receptor Occupancy:

If median RO of any dose is < 20%, the sponsor may consider dropping that dose;

If the median RO for all doses is > 90%, the sponsor may consider adding or replacing a dose in Part 2 of the 
study to ensure an adequate pharmacodynamic range (dose not to exceed 12.5 mg weekly).
Dose decrease and/or reduction of frequency of administration may also be considered if RO results fall outside the 
parameters indicated above. This adjustment may occur for safety reasons or in case unforeseen RO profiles 
observed in SLE patients. The decision to adjust dose and/or frequency will be taken after review of the data by the 
clinical team.
Interim analysis for futility and dose adaptation at Day 85:
After 30 subjects per treatment arm (including the subjects from Part 1) have completed at least 84 days of the 
treatment period or discontinued the treatment, an interim analysis will be conducted to assess the futility of the 
BMS-931699 dose arms and the overall safety. The results of the interim analysis will be reviewed by an unblinded 
sponsor team who will provide recommendations to the blinded study team. The blinded study team will make the 
decision. The unblinded BMS team may recommend to:

Maintain the current design;

Drop a certain dose arm(s) and equally randomize the remaining unallocated subjects to the remaining arms;

Stop the study if all dose arms need to be dropped for safety or futility reasons.
The interim analysis for futility and dose adaption will be performed on the BICLA response at Day 85 and 
Day 169, of those 30 subjects per arm who have completed 85 days of treatment or discontinued the treatment, using

a Bayesian predictive approach.2 This analysis assumes that the BICLA response at Day 85 and at Day 169 in the 
subjects who have not yet been observed will be similar to those observed for the subjects included in the interim 
analysis at Day 85 and Day 169, respectively. As such, the unobserved data will be simulated from the predictive 
distribution conditional on the interim data and the prior distribution of the treatment difference (using a 
non-informative prior). Under the Bayesian framework, the posterior distribution of the treatment difference 
(BMS-931699 active dose – Placebo) will be constructed to determine the predictive probability of a successful 
outcome (ie, reach statistical significance) at Day 169. Based on computer simulations of the operating 
characteristics of the study design, the futility threshold in this interim analysis is set to 0.2. For the comparison of 
interest, if the predictive probability of a successful outcome at the planned end of the trial falls below 0.2, that 
BMS-931699 dose arm is deemed futile in terms of BICLA response. However, the final futility will also 
incorporate the results from SRI(4), ACR28 and some biomarkers (C3, C4, ANA and anti-dsDNA). 
The proposed stopping rules at the interim analysis, based on the futility assessment and the overall safety 
assessment, are as follows:

Rule 1: Drop the futile dose arm(s) and the dose arm cannot be dropped until the lower dose arm has been 
dropped.

Rule 2: Drop the dose arm(s) with safety issues identified;

Rule 3: If safety issues are identified in all dose arms or all dose arms are futile, stop the study.
In case dosing arms are dropped following the interim analysis, the remaining unallocated subjects will be 
randomized into the remaining arms.
If the predictive probability of success for each active arm versus placebo is greater than or equal to 0.9, then the 
BMS team may also recommend adding an additional dose arm at lower dose level than current active doses to 
explore a suboptimal dose.
In that case, the remaining unallocated subjects with up to 40 additional subjects will be randomized into the 
remaining arms and the new dose arm based on the new randomizations schedule.
Analyses for the long-term extension period:
The LTE period starts when a subject receives at least one post Day 169 dose. The analysis based on this period is 
descriptive in nature.
Populations of Analysis
All Subjects who received at least one dose post Day 169. 
Demographics and Baseline Characteristics
Categorical parameters will be summarized using frequency counts and percentages. Continuous parameters will be 
summarized through means, SD, median, and range. The baseline (Day 1) is defined as the start of study medication 
(the same as baseline in Double-blind period). The baseline results will be based on LTE analysis population.
Efficacy Analyses
For continuous secondary endpoints (e.g. SLEDAI, MDGA etc.) point estimates and 90% confidence intervals for 
mean change from baseline to subsequent time points (in LTE period) within each treatment groups will be 
provided. For binary endpoints (BICLA Response, SRI(X) etc.), point estimates and 90% confidence intervals (CIs) 
will be provided using normal approximation within each treatment group. The assessment windows for LTE period 
will be based on the first LTE dose date; the baseline to assess responses or changes still refers to the Day 1 
assessment (the same as baseline in Short-term Period). The results will be presented by treatment groups. All 
Analyses will be based on as-observed data; hence no imputation will be implemented. No statistical testing 
including p-value computation will be performed.
Safety Analyses
The evaluation of long term safety of the selected dose(s) will be based on clinical adverse events, vital signs and 
laboratory abnormalities reported during the LTE period. Frequency distributions and individual listings of all

Intense safety monitoring will be put in place during the entire study (short-term and long-term 
extension periods), allowing early detection of any safety signals. Specifically, the following
measures will be put in place:

Patients will undergo safety evaluation at each clinic visit.

Investigator will conduct safety evaluation before dosing.

Continuous internal data review by unblinded clinical monitoring team. 

Monitoring team to refer to independent external DMC any safety issue deemed to be of 
relevance. 

Independent external DMC to meet at regular intervals throughout the entire study to review
all data (frequency to be determined in conjunction with DMC).

Stopping rules to be implemented under DMC guidance.
DMC and internal safety monitoring activities initiated in Part 1 will continue into Part 2
and will be ongoing until the end of the study, including the long-term extension.
In summary, the potential overall benefit ratio for BMS-931699 treated subjects in this trial 
appears favorable. In order to minimize the overall risk to participating subjects, this protocol has 
inclusion and exclusion criteria appropriate to the population and proposed treatments, 
exclusionary screening tests [chest x-ray, Quantiferon Gold testing (or other interferon gamma 
release assay test, such as T-SPOT) wherever appropriate, risk factor/age specific breast 
screening, medical history], and specific follow-up safety assessments. In addition, the AEs and 
SAEs will be reviewed on an ongoing basis by the medical monitors and pharmacovigilance 
group to look for trends and any safety issues.

which is likely to affect, to a significant degree, the safety or physical or mental integrity of the 
subjects of the study or the scientific value of the study.
Personnel involved in conducting this study will be qualified by education, training, and 
experience to perform their respective tasks.
This study will not use the services of study personnel where sanctions have been invoked or 
where there has been scientific misconduct or fraud (eg, loss of medical licensure, debarment). 
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 Investigator Brochure 
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(s) 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(s) 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(s) 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(s) must also include a statement that BMS and regulatory authorities have 
direct access to subject records. 
Subjects unable to give their written consent (eg, stroke or subjects with or severe dementia) may 
only be enrolled in the study with the consent of a legally acceptable representative. The subject 
must also be informed about the nature of the study to the extent compatible with his or her 
understanding, and should this subject become capable, he or she should personally sign and date 
the consent form as soon as possible. The explicit wish of a subject who is unable to give his or 
her written consent, but who is capable of forming an opinion and assessing information to 
refuse participation in, or to be withdrawn from, the clinical study at any time should be 
considered by the investigator.
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 Phase 2, parallel-arm, randomized, double-blinded, multicenter, international study, 
with an adaptive design.
The study will comprise a short-term period (Part 1 and Part 2), and a long-term extension (LTE) 
period.
Part 1 of the short-term period will focus on assessing safety and RO and will be limited to a 
maximum of 50 patients (approximately 6-10 patients/arm) who will be included in the 
Safety/RO interim analysis (IA). These patients will continue study treatment beyond the IA for 
Safety/RO and be treated for up to 24 weeks and be followed for 6 additional weeks after 
treatment is completed. Treatment could be shorter if IA for Safety/RO analysis indicates one or 
more arms should be dropped.

lulizumab pegol
Part 2 of the short-term period will start once cumulative safety profile is considered acceptable 
and RO data for 6-10 subjects per cohort dosed for >28 days is available and the interim analysis
from Part 1 is completed. Approximately 300 subjects will be randomized into this part of the 
study (number of patient to be randomized into Part 2 may increase based on the results of the 
futility interim analysis). 
All subjects will undergo screening evaluations to determine eligibility and allow down titration 
of prednisone (or prednisone equivalent) prior to administration of study medication. The 
screening period will have a duration of approximately 28 days (+/- 2 days). All eligibility 
criteria must be met prior to Day 1. In the event of technical difficulties leading inconclusive 
assessments that would go beyond the allowed window, the study medical monitor must be 
consulted prior to conducting Day 1. On Day 1, eligibility of subjects will be confirmed and
eligible subjects will receive their first dose of study medication.
Dose may be adapted based on results of the planned interim analyses from Part 1 and Part 2, as 
follows:

Safety and RO interim analysis: safety and RO analysis will be performed when 
approximately 6 to 10 subjects per arm have reached Study Day 29. Based on the results of 
this analysis, dose arms(s) may be adjusted or may be dropped.

Interim analysis for futility and dose adaptation on BICLA response, SRI response, 
ACR28 and some SLE biomarkers (such as auto-antibodies, complement levels, etc.) with 
possible exploratory exposure response analysis, will be performed when approximately 
30 subjects per arm have reached Study Day 85 (12 weeks), including subjects from Part 1 
and Part 2, of treatment or have discontinued prior to reaching study Day 85). Analysis will
be performed by an unblinded Sponsor team, while maintaining blind at the site and subject
level. Based on the results, the dose levels and sample size may be modified.

Ongoing assessment of safety will be performed by an independent Data Monitoring 
Committee (DMC) and an internal unblinded safety monitoring team. Both entities may 
make recommendations to the Sponsor regarding conduct of study and dose adjustment based 
on safety observations.
Following interim analyses and DMC reviews, dose arm(s) may be modified based on the 
results, as follows:

If one or more arms are added, future randomizations will include the new arm(s). 

If one or more arms are dropped for safety reasons, randomization into that arm will be 
terminated and all subjects currently randomized to that or those arm(s) will be discontinued
from receiving study medication.

If one or more arms are dropped due to inadequate RO, there will be no new randomizations 
into that dose arm; subjects currently randomized may continue at the Investigator discretion. 
The long-term extension (LTE) period is optional and will include eligible subjects who have 
completed Day 169 (week 24) of treatment and consent to participate. This period of the study 
will remain blinded but will no longer have a placebo arm. Eligible subjects will remain on their

originally-assigned dose arm, unless they were on the placebo arm during the short-term period. 
Placebo-arm subjects will be re-randomized into one of the existing active arms at Day 169
(24 weeks). Re-randomization of the placebo subjects will be done by IVRS and only the 
unblinded pharmacist/drug preparer will know the new randomization arm. The LTE will remain 
blinded to the study team and study personnel. 
The long-term extension period will not have interim analyses for dose adaptation. However, the 
BMS unblinded safety committee will continue to review the safety data and discuss it with the 
DMC (also unblinded), as needed. During their evaluation of adverse events, if a significant 
safety concern is identified, these two committees may propose that one or more dose arms are 
dropped. If one or more dose arms are dropped for safety reasons, all subjects currently receiving 
that or those dose(s) will be discontinued from receiving study medication.

Overall Study Design
Part 1
• Limited to approximately 30 to 50 subjects (6-10 per arm).
• Interim analysis for safety and RO once 30-50 subjects have reached Day 29 (4 weeks).
• These subjects will continue study treatment beyond the interim analysis for safety and RO and 
will be treated for up to 24 weeks, and followed for 6 additional weeks after treatment is completed 
or discontinued. Treatment could be shorter if dose arm(s) are dropped. 
Intense safety monitoring by the 
DMC, in collaboration with an 
internal safety monitoring team, 
will be performed during Part 1 
and continue during Part 2.
DMC and unblinded internal 
safety monitoring activities will 
continue during long-term 
extension. 
Part 2
• Will start once cumulative safety profile is considered acceptable and RO data for 6-10 subjects 
per arm for >28 days are available and the interim analysis from Part 1 is completed. Results of the 
interim analysis in Part 1 and DMC reviews may result in treatment arm(s) modifications. 
• Each treatment arm will enroll approximately 70 subjects, including subjects from Part 1.
• Part 2 will have an interim analysis for futility once approximately 30 subjects per arm complete 
Day 85 (12 weeks), or have discontinued. As in the interim analysis from Part 1, results of the 
interim analysis in Part 2 and DMC reviews may result in treatment arm(s) modifications. 
• All subjects could be treated for up to 24 weeks and followed for 6 additional weeks after 
treatment is completed or discontinued. Treatment could be shorter if dose arm(s) are dropped. 
Long-Term Extension
• Subjects completing Day 169 (24 weeks) on study medication may be eligible to enter an optional 
long-term extension (LTE) period.
• The LTE period will remain blinded but will no longer have a placebo arm.
• Subjects will remain on their originally-assigned treatment arm unless they were on 
placebo. 
• Subjects initially randomized to placebo arm will be automatically re-randomized into one 
of the existing active arms at Day 169 (24 weeks).

Physical examinations, vital sign measurements, 12-lead electrocardiograms (ECG), and clinical 
laboratory evaluations will be performed at selected times throughout the study. Subjects will be 
closely monitored for adverse events throughout the study. Blood will be collected for 
pharmacokinetic (PK) and pharmacodynamic measurements as well as for safety monitoring. 
The approximate duration of the short-term period (Parts 1 and 2) of the study is 238 days 
(34 weeks), including: 28 days (4 weeks) of screening, 168 days (24 weeks) of treatment, and 
42 days (6 weeks) of safety follow-up. If subject is eligible and opts to continue into LTE, the 
42-day follow-up visit will not be performed after the short-term period is completed and subject 
will enter LTE directly. If subject opts not to enter LTE then a follow-up visit will be completed 
42 days after end of treatment. At the time of writing there is no defined end date to the 
long-term extension period, however, the LTE provision may be further adjusted based on results 
from the ongoing lulizumab development program. Subjects discontinuing treatment during the 
LTE period will complete the follow-up visit approximately 6 weeks after receiving their last 
dose of study medication.
Subjects randomized in the short-term period (either Part 1 or Part 2) will be treated for up to 
24 weeks, will have the same procedures performed and will follow the same visit schedule. All 
subjects will account for the approximately 350 subjects planned to be randomized in this study.

Approximately 125 sites will participate in this study, which will be conducted globally and 
should include, but will not be limited to, participation of countries located in North America and 
Europe.
Subjects who discontinue from the study will have one follow-up visit, approximately 42 days 
(6 weeks) after receiving their last dose of study medication, to perform safety assessments. 
During this period, when subjects are no longer receiving study drug, it is recommended that 
they are not treated with other biologic therapy, due to the compound’s half-life. However, this 
decision remains at the investigator’s discretion. If the study drug becomes commercially 
available, and if the subject chooses to receive treatment with the commercial product, then the 
subsequent post-dose follow-up visits are not required.
3.2
Post Study Access to Therapy
At the time of writing there is no defined end date to the LTE period, however, the LTE 
provision may be further adjusted based on results from the ongoing lulizumab pegol 
development program. At the conclusion of the study, subjects who continue to demonstrate 
clinical benefit will be eligible to receive BMS supplied study drug. Study drug may be provided 
via an extension of the study, a rollover study requiring approval by responsible health authority 
and ethics committee or through another mechanism 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.

Women of Childbearing Potential
Women 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 in the absence of other biological or physiological causes. In addition, 
famales under the age of 55 years must have a documented 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 
judgment in checking serum FSH levels. If the serum FSH level is > 40 mlU/ml at any time 
during the washout period, the woman can be considered postmenopausal. 

1 week minimum for vaginal hormonal products (rings, creams, gels)

Criteria for Long-Term Extension
Subjects who enter the short-term period according to the eligibility criteria outlined in 
Sections 3.3.1 and 3.3.2, and who complete 24 weeks on study medication are eligible for 
participation in the LTE period. The LTE period will remain blinded but will no longer be 
placebo controlled, as subjects completing Day 169 in the placebo arm will be re-randomized to 
existing active arms. 
A separate informed consent must be signed to enter the LTE period.
The class and dose of background therapies is recommended to remain the same as in the short 
term period. However, temporary rescue therapy with prednisone (or prednisone equivalent) to 
transiently manage SLE disease activity may be instituted. The increase in prednisone should not 
exceed a total daily dose of 20 mg, and must return to the previous stable dose within 14 days. 
Subjects requiring more than 14 days of rescue therapy will be discontinued.
The use of cyclophosphamide, any intravenous, any intra-articular or biologic agent remains
prohibited during LTE. Any changes to or new concomitant therapies must be recorded on the 
CRF.

Other Restrictions and Precautions
Active SLE and its treatment are associated with increased risk of infection. Subjects should be 
provided information about the signs of the most common serious infections (eg, pneumonia, 
sepsis) and must have the knowledge and means to access appropriate medical care.
3.5
Discontinuation of Subjects following any 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 and/or participation in the study

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)

Development of new active manifestations of lupus requiring treatment with any 
non-protocol approved medications during the study.

Inability or subject’s failure to comply with the protocol requirements.

Subject who misses more than 3 consecutive weekly doses.

Pregnancy

Treated with prednisone (or prednisone equivalent) at a total daily dose exceeding 20 mg
and/or for more than 7 days (short-term period) or more than 14 days (long-term extension 
period). 
Patients should discontinue from study, perform End of Treatment and Follow-up Day 42 visits, 
and receive standard of care according to local guidelines.
In the case of pregnancy, the investigator must immediately notify the BMS Medical 
Monitor/designee of this event. If any female subject becomes pregnant she will be immediately 
discontinued from the study.
All subjects who discontinue investigational product 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 CRF page.
3.6
Post Study Drug Follow up
In this study, assessment of lupus disease activity is a key endpoint 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.
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.

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 product is BMS-931699 Injection.
4.2
Non-investigational Product
There are no non-investigational products in this study.
4.3
Storage and Dispensing
The product storage manager should ensure that the study drug 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 drug arise, the study drug should not be 
dispensed and contact BMS immediately.
Please refer to section 9.2.2 for information on investigation product record retention and 
Section 4.8 for return and destruction instructions.
Study drug not supplied by BMS will be stored in accordance with the package insert.
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).
Preparation for Subcutaneous (SC) Use:
For SC dosing, no dilution of the drug product solution (12.5 mg/mL) will be required for doses 
of 12.5mg. However, doses of 5mg and 1.25mg will require dilution. A commercially available 
appropriately sized sterile needle and appropriate syringe should be used for withdrawal and 
administration (refer to the pharmacy reference instruction document for further details on the 
subcutaneous preparation and administration for materials and instructions, provided separately). 
The placebo for BMS-931699 injection is normal saline solution, which is administered in a 
similar fashion as described for the BMS-931699 injection. Normal saline to use as placebo will 
not be provided by the Sponsor.
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 (36°- 46° F) with 
protection from light 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. The subjects should be 
monitored for at least 1 hour after each injection for potential reactions.
4.4
Method of Assigning Subject Identification
Subjects will be randomized to receive either BMS-931699 or placebo according to a computer-
generated randomization scheme prepared by a Randomization Coordinator within the Drug 
Supply Management Department of BMS Research and Development. 
During the Screening visit, the investigative site will call into the enrollment option of the 
Interactive Voice Response System (IVRS) 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 sequential subject numbers starting with 00001, eg, 00001, 00002, 00003.... 
00010. The patient identification number (PID) will ultimately be comprised of the site number 
and subject number. For example, the first subject screened (ie, enrolled) at site number 1, will 
have a PID of 0001 00001. Once it is determined that the subject meets the eligibility criteria 
following the Screening visit, the investigative site will call the IVRS to randomize the subject 
into the treatment period. 
4.5
Selection and Timing of Dose for Each Subject
4.5.1
Double-blind Administration of BMS-931699 or Placebo
On Day 1, subjects will be randomized to one of the following dosing arms in a 1:1:1:1:1 
randomization scheme:

BMS-931699 at 12.5 mg weekly sub-cutaneous (SC) injection

BMS-931699 at 12.5 mg every other week (EOW) SC injection

BMS-931699 at 5 mg EOW SC injection

BMS-931699 at 1.25 mg EOW SC injection

Placebo SC injection (short-term period only)
The Pharmacist (or qualified drug preparation person) will know the randomized assignments 
and will prepare the appropriate dose of active BMS-931699 or placebo accordingly. The 
prepared drug must be supplied to study personnel in a manner such that neither study personnel 
nor subjects will be aware of whether they receive active drug or placebo. 
Every randomized subject will be required to come to the clinic/research center weekly to be 
dosed. This will ensure double-blind is maintained despite the variability of regimens. Subjects 
randomized to weekly subcutaneous injections of either placebo or BMS-931699 will be dosed 
weekly as per schedule and subjects randomized to one of the every other week arms will be 
alternating between receiving a subcutaneous injection of BMS-931699 one week and one of 
placebo the following week.
Every randomized subject will be required to remain on site for at least 1 hour after each dose to 
ensure safety.

4.5.1.1
Administration Window
A subject’s scheduled dosing may be administered within 2 days of the target day to adjust for 
the subject’s and/or the site personnel’s convenience. 
Refer to Section 4.5.2.1 for dose modifications in the presence of an adverse event.

Dose Modifications in the Absence of Adverse Events
In the absence of adverse events, subjects will complete their scheduled injection as prescribed 
by protocol. A subject’s scheduled dosing may be administered within ± 2 days of the target day 
to adjust for the subject’s and/or the site personnel’s convenience.

If the study medication cannot be administered within 2 days of the target date, that 
scheduled dose should be skipped, which means subject will miss one (1) dose. The next 
dose of study medication should then be administered on the next targeted administration day
(2 days) as originally planned. For example, the Day 15 dose could not be administered 
until Day 17 and subject comes to the study site to receive it on Day 19. The planned Day 15
dose should not be given at Day 19 and the next dose will be administered on Day 22
(2 days). In this example, one missed dose will be reported in the eCRF.
Dose Modifications for Adverse Events
If there is evidence of toxicity (eg, abnormal laboratory tests or clinical adverse events) that, in 
the judgment of the Investigator, could place the subject at increased risk, study drug 
administration should be interrupted. Subjects may be considered eligible to receive further study 
medication treatment only if full resolution of the adverse event is documented, as follows: 

If the adverse event completely resolves and the study medication is administered within 
2 days of the target date, the next dose should be administered on the originally planned 
dosing day with no missed doses.

If the adverse event completely resolves but study medication cannot be administered within 
2 days of the target date, that scheduled dose should be skipped (which means subject will 
miss one (1) dose). The next dose of study medication should then be administered on the 
next targeted administration day as originally planned (2 days). For example, the Day 15
dose could not be administered until Day 17 and adverse event resolution occurs on Day 19. 
The planned Day 15 dose should not be given at Day 19 and the next dose will be 
administered on Day 22 (2 days). In this example, one missed dose will be reported in the 
eCRF.
4.5.3
Corticosteroids (Prednisone or Prednisone Equivalent) Dosing

Prior to Randomization: Corticosteroids (prednisone or prednisone equivalent; refer to 
Appendix 1) may be used in accordance with the Investigator’s clinical judgment and best 
standard of care. A maximum daily dose of 30mg/day is acceptable to be eligible for the

study and start screening; however, daily dose must be tapered down to a maximum of 
10mg/day for at least 5 days prior to Day 1 (randomization day).

Study Day 1 (randomization day): subjects requiring the use of prednisone (or prednisone 
equivalent) will be on a maximum dose of 10mg/day.

Post Day 1 (after initiation of study therapy): 

For subjects who flare or need to increase their prednisone (or prednisone equivalent) to 
control disease activity a one-time increase of up to a maximum daily dose of 20 mg/day
for up to 2 consecutive days will be allowed to transiently manage disease activity.

A subject who requires a total daily dose of prednisone (or prednisone equivalent) 
exceeding 20 mg/day or who has another flare after the first rescue therapy, will be 
considered a treatment failure.

A subject who meets the treatment failure criteria as described above may continue on 
study medication; however, a subject requiring more than 20 mg/day of prednisone 
(or prednisone equivalent) for more than 7 days in the short-term period, or more than 
14 days in the long-term extension period, will be discontinued.
Tapering of steroids during the course of the study is encouraged and should be evaluated 
at all visits. Once subject has received the first dose of study drug, prednisone 
(or prednisone-equivalent) may be tapered down at the discretion of the Investigator.
4.5.4
Rescue Therapy
4.5.4.1
Short- Term Period
A one-time increase of up to a maximum daily dose of 20 mg/day for up to 2 consecutive days 
will be allowed to transiently manage disease activity and will not be considered a treatment 
failure. 

A subject who requires a total daily dose of prednisone (or prednisone equivalent) 
exceeding 20 mg/day or who has another flare after the first rescue therapy, will be 
considered a treatment failure. 

A subject who meets the treatment failure criteria based on prednisone use may continue 
on study medication; however, a subject requiring more than 20 mg/day of prednisone 
(or prednisone equivalent) for more than 7 days in the short-term period, will be 
discontinued.
The use of rescue therapies other than prednisone (or prednisone equivalent), such as 
cyclophosphamide, any intravenous, any intra-articular or biologic agent is prohibited.
Any changes to or new concomitant therapies must be recorded on the CRF.
4.5.4.2
Long-Term Extension Period
The class and dose of background therapies is recommended to remain the same as in the short

4.6
Blinding/Unblinding
4.6.1
Blinding at the Study Sites
The subjects and clinical assessor(s) will not be aware of which treatment is being administered 
to the subjects enrolled in the study. The pharmacist (or qualified drug preparation person) will 
be unblinded to study medication (BMS-931699 or placebo).
The pharmacist (or qualified drug preparation person) will know the randomization assignments 
and prepare the appropriate dose of active BMS-931699 or placebo accordingly. The prepared 
drug must be supplied to study personnel in a manner such that neither study personnel nor 
subjects will be aware of whether they receive active drug or placebo.
4.6.2
Unblinding of the Study Sites
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 active product. It is highly desirable that the decision to unblind treatment assignment 
be discussed with the Medical Monitor, but the investigatory 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.
For information on how to unblind in an emergency, consult the IVRS manual.
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 non-emergency purposes should be discussed with the 
Medical Monitor.

In case of an emergency, the Investigator(s) has unrestricted access to randomization information 
via the Interactive Voice Response System (IVRS) and is capable of breaking the blind through 
the IVRS system without prior approval from sponsor. Following the unblinding the Investigator 
shall notify the Medical Monitor and/or Study Director.
4.7
Treatment Compliance
Subject will be dosed at the study site where documentation of injection and compliance will be 
maintained.
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. 
Any unused study drugs can only be destroyed after being inspected and reconciled by the 
responsible BMS Study Monitor unless study drug containers must be immediately destroyed as 
required for safety, or to meet local regulations (eg, cytotoxics or biologics). 
On-site destruction is allowed provided the following minimal standards are 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.

Written procedures for on-site disposal are available and followed. The procedures must be 
filed with the site’s SOPs and a copy provided to BMS upon request.

Records are maintained that allow for traceability of each container, including the date 
disposed of, quantity disposed, and identification of the person disposing the containers. The 
method of disposal, ie, incinerator, licensed sanitary landfill, or licensed waste disposal 
vendor must be documented.

Accountability and disposal records are complete, up-to-date, and available for the Monitor 
to review throughout the clinical trial period.
If conditions for destruction cannot be met the responsible BMS Study Monitor will make 
arrangements for return of study drug.
It is the investigator’s responsibility to arrange for disposal of all empty containers, 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.
4.9
Return of Study Drug
If study drug will not be destroyed upon completion or termination of the study, all unused 
and/or partially used study drug that was supplied by BMS must be returned to BMS. The return 
of study drug will be arranged by the responsible Study Monitor. 
Arrangements for the return of study drug will be made by the responsible Study Monitor.

Retesting During Screening
5.1.2
Period
A single-retesting of laboratory parameters and/or other assessments during Screening period 
will be permitted (in addition to any parameters that require a confirmatory value), only if 
medically indicated, if there is evidence a laboratory sample was mislabeled, was inadequately 
processed and/or deteriorated in transit to the central laboratory.
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. This will also apply to subjects who are being re-screened.
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 for recording body weight, a 
12-lead ECG machine, and a calibrated sphygmomanometer and thermometer for vital signs 
assessments. The site will have urine collection containers, a centrifuge, a heated plaque, 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.
BMS will provide a BMS-approved protocol and any amendments or administrative letters 
(if required), and investigator brochure. 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 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. Physician Global Assessment of disease activity worksheet will be 
completed by the investigator and will then be entered with the EDC tool. Subject completed 
Quality of Life Questionnaires will be retained at the investigational site. 
Study supplies and documents (eg, electronic Case Reports Forms, patient drug logs, etc.) will be 
provided to the study center by BMS. Urine pregnancy test kits, laboratory specimen collection 
kits and instructions for collection will be provided by central laboratory vendor. IVRS 
worksheets and instruction manuals will be provided by the IVRS vendor.

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 Visit” 
approximately 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.
All assessments should be performed or administered prior to study drug administration 
unless otherwise indicated. Furthermore, patient’s assessments (ie FACIT-F, SF-36 and 
Subject’s Global Assessment) 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.
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 Outcome Measures: 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 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) and an internal safety monitoring team. Both entities may make recommendations to the 
Sponsor regarding conduct of study and dose adjustment based on safety observations.
Titers of anti-CMV and EBV antibodies will be obtained at baseline, 12 weeks and 24 weeks to 
monitor for viral reactivation.

Clinical Laboratory Testing
Blood and/or urine samples will be obtained prior to injection at all visits from each subject 
entered in this study. Any laboratory test result that the Investigator considers clinically 
relevant should be recorded on the appropriate Adverse Event page of the CRF

For the Lipid Panel, a fasting sample is required. At least 10 hours prior to the collection 
time, subjects should not consume food; only water is allowed. Subjects with an abnormal Lipid 
Panel may be referred back to their primary care provider for further management if warranted.
Urine or serum pregnancy tests will be performed within 24 hours prior to dosing, for all 
WOCBP. If any female subject becomes pregnant she will be immediately discontinued from the 
study.
If a WOCBP advises the investigational staff that she has had amenorrhea for 12 consecutive 
months while the study is ongoing and menopause is a diagnostic consideration, a serum follicle 
stimulating hormone (FSH) level should be taken and testing performed at the central laboratory 
to determine if her FSH level is > 40 mIU/mL. After the level has been confirmed and the 
diagnosis of menopause has been determined by a treating physician, pregnancy testing at each 
visit will no longer be required for the subject as she is no longer of child-bearing potential. 
If additional or follow-up monitoring of subject safety, eg, potential toxicity or features of 
active SLE is required, the investigator may obtain samples for additional laboratory tests 
if deemed necessary after discussion with the BMS study team.

5.3.3
Tuberculosis Screening and Chest X-Ray
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 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, T-spot®, QuantiFERON®], preferably performed centrally. 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 study medical monitor.
Subjects with a positive screening test will not be eligible for the study unless they have 
completed at least four (4) weeks of 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 and a 
negative IGRA test (Quantiferon or T-Spot) is confirmed prior to Day 1.
5.3.4
Physical Examination
Complete and/or interim physical examinations may be performed by a Doctor of Medicine 
(MD), or someone who is authorized to perform the examinations by training and has been 
delegated this task by the principal investigator. While the interim physical examination may not 
be as comprehensive as the initial full examination, key aspects of the interim examination 
should evaluate important body systems as clinically indicated. These body systems can include 
lymph nodes, liver, spleen, and breast at the discretion of the examiner. An 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 all visits throughout the study. Documentation of who performed the 
examination is to be recorded in source notes.
5.4
Efficacy Assessments
Clinical assessments of response should be performed by the same assessor(s) and at 
approximately the same time of day throughout the duration of the study. 
5.4.1
Primary Efficacy Assessment
5.4.1.1
Short-Term Period
Primary efficacy assessment is a composite endpoint, the BICLA, which includes BILAG-2004, 
SLEDAI-2K (30 day)20, Physician Global Assessment of disease activity (MDGA) and no 
treatment failure. The BILAG-2004 index was selected as the central score on the basis of its 
comprehensiveness, ability to capture partial improvement, and the clinical relevance of its 
scoring system. BILAG assessments will be performed by the investigators, and grades will be 
determined by an independent central reader group.
5.4.1.2
Long-Term Extension Period
Primary efficacy assessments during the long-term extension will be the same as in the 
short-term period, in order to assess long-term durability of response.
5.4.2
Secondary Efficacy Assessments
5.4.2.1
Short-Term Period
Training and instruction on BILAG 2004 index assessment will be provided and discussed at the 
Investigator’s Meeting or at workshops. The response measure (BILAG) will be reviewed and 
discussed with the investigational staff at the Investigator Meeting or other forum as a method of 
standardizing the grading between the investigational staffs. All Investigative site personnel 
performing BILAG evaluations must be trained and certified. 
The BILAG index measures and reports disease activity in different organs/systems separately. 
The BILAG score is calculated for each of nine systems depending on the clinical features

present and whether they are new, worse, the same or improving in the last 4 weeks compared 
with previously. A BILAG “A” represents the presence of one or more serious features of lupus. 
A BILAG “B” represents more moderate features of the disease. A BILAG “C” includes only 
mild symptomatic features. A BILAG “D” represents only prior activity with no current 
symptoms due to active lupus. A BILAG “E” represents an organ that has never been involved. 
Assessments used to determine BILAG score must be performed by the Investigator, or a 
BILAG certified (an individual who has passed the BMS sponsored BILAG Certification Test) 
Sub-Investigator. The Sub-Investigator may be a Doctor of Medicine (MD), or someone who is 
authorized to perform the examinations by training and has been delegated this task by the 
principal investigator. Changes in therapy based on any clinical or laboratory assessment must be 
approved by the Investigator or a MD/DO Sub-Investigator.
5.4.2.2
Long-Term Extension Period
Secondary efficacy assessments during the long-term extension will be the same as in the short-
term period, in order to assess long-term durability of response.
5.5
Pharmacokinetic Assessments
5.5.1
Short-Term Period
Pharmacokinetics of BMS-931699 will be derived from serum concentration versus time data. 
The pharmacokinetic parameters to be reported include Ctrough (ng/mL), which will be 
measured from serum samples collected as defined Table 5.5.3.
Additional blood samples will be obtained according to Table 5.5.3, which specifies pre-dose 
samples as well as post-dose samples on Day 46 and Day 48. If both post-dose samples cannot 
be obtained at these times (ie, Days 46 + Day 48), the 2 samples may be obtained on (Days 60 + 
Day 62) OR (Days 74 + Day76). 
Population PK (PPK) analysis maybe performed using PK data from the current proposed study 
in SLE patients. Results of the PPK analysis may also be used to characterize the 
exposure-response (E-R) relationship in BMS-931699 by means of the individual model 
predicted exposure and efficacy/safety data. Further, the effect of covariates (demographic and 
clinical) on efficacy/safety may be explored in the E-R analyses. Results of the PPK and E-R 
analyses will be reported separately if performed.

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.
The causal relationship to study drug is determined by a physician and should be used to assess 
all adverse events (AE). 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). BMS, as sponsor of the study, 
commits to declare safety events in accordance with the regulation in force in each country.
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 drug induced liver injury (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

6.1.1
Serious Adverse Event Collection and Reporting
Sections 5.6.1 and 5.6.2 in the Investigator Brochure (IB) 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 
and within 42 days of discontinuation of dosing.
The investigator should 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 should 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 should 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. 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. The paper forms should be used and submitted immediately, only 
in the event the electronic system is unavailable for transmission. 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 should 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, a follow-up SAE report should be sent within 24 hours to the BMS 
(or designee) using the same procedure used for transmitting the initial SAE report.
All SAEs should be followed to resolution or stabilization.
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 (paper or 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 drug 
discontinued or interrupted

Any laboratory test result abnormality that required the subject to receive specific corrective 
therapy.
It is expected that whenever 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 investigational product, 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, 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 and in accordance with SAE reporting procedures 
described in Section 6.1.1.
If any female subject becomes pregnant she will be immediately discontinued from the study.

In the rare event that the benefit of continuing study drug is thought to outweigh the risk, after 
consultation with BMS, the pregnant subject may continue study drug after a thorough 
discussion of benefits and risk with the subject.
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
subject unless contraindicated by pregnancy (eg, x-ray studies). Other appropriate pregnancy 
follow-up procedures should be considered if indicated.
The investigator must immediately notify the BMS (or designee) Medical Monitor of this event 
and complete and forward a Pregnancy Surveillance Form to BMS (or designee) within 24 hours 
and in accordance with SAE reporting procedures described in Section 6.1.1. 
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.
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.).
6.6
Potential Drug Induced Liver Injury (DILI)
Whenever 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.

AE’s of Special Interest
Although there are no identified risks for BMS-931699, BMS has developed a list of events of 
special interest for the BMS-931699 program based on the known biologic class effects, the 
mechanism of action of BMS-931699, overall potential consequences of immunosuppression, 
and preliminary data from unblinded clinical trials. Event categories of special interest for this 
study may include, but are not limited to:

Infections

Autoimmunity

Malignancies

Injection-related reactions
Note: Another event of special interest based on the biologic class effect, albeit not an adverse 
event in itself, is Immunogenicity, which will be monitored during the entire study. Adverse 
events in subjects who develop anti-BMS-931699 antibodies will be monitored as AE’s of 
special interest.

DATA MONITORING COMMITTEE AND OTHER EXTERNAL 
COMMITTEES
An external Data Monitoring Committee (DMC) will be used in this study. The Committee’s 
scope of responsibility will be limited to monitoring safety by masked treatment group; 
Committee may request treatment codes and/or efficacy summaries if indicated for safety/benefit 
assessment. The Committee will comprise 1 biostatistician and 2 clinicians with expertise in 
SLE.
Data summaries and listings will be provided to the DMC to facilitate their safety and efficacy 
assessment at the regularly scheduled times as well as on an ad hoc basis if needed. DMC data 
monitoring will commence when 5 subjects have been dosed. From that time, DMC monitoring 
will be performed approximately every 6-8weeks (during Part 1) and quarterly during Part 2 
(with the agreement of DMC and BMS, this schedule may be changed depending on the rate of 
subject accrual). The DMC will review safety data including serious adverse events and events 
of special interest (eg, infections), focusing on early signal detection. The DMC will also 
evaluate the rates of observed increases of clinical disease activity of SLE and opportunistic 
infections compared to the background rates expected in this study population based on a review 
of the relevant literature. Further details on the 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.
In collaboration with the DMC, an unblinded internal safety monitoring team will review the 
safety data throughout the study and will provide recommendations to the blinded study team.
An Adjudication Committee will be used in this study. Scope of responsibility will include, but 
will not be limited to, adjudication of SLE eligibility criteria, new “A” and “B” BILAG flares
and cross-validation of the instruments used in this study to assess the disease being studied.

STATISTICAL CONSIDERATIONS
8.1
Sample Size Determination
The sample size calculation is based on power to compare the proportion of subjects who 
achieve BICLA response (the BICLA response rate) at Day 169 between BMS-931699 dose arm 
and placebo arm. With a one-sided continuity corrected chi-squared test at significance 
level 0.05, data from 70 randomized and treated subjects per arm will provide at least 89% power 
to detect a 25% increase in the BICLA response rate in the active treatment arm(s) [(ie, 50% 
response rate in BMS active arm(s)] compared to placebo, and provide 74% power to detect a 
20% increase in the BICLA response rate in the active treatment arm(s) [(ie, 45% response rate 
in BMS active arm)] compared to placebo, assuming that the placebo arm has 25% response rate 
which is reasonable based on the EMBLEM phase 2 trial results21. No adjustment will be made 
for multiplicity. Subjects who discontinue treatment/study prior to Day 169 will contribute to the 
data that will be analyzed for BICLA response at Day 169 (discontinuation will indicate no 
BICLA response). Therefore, no adjustment will be made for discontinuations.
The primary efficacy analysis will be conducted on all randomized patients who received at least 
one dose of the study drug. In order to get 70 randomized and treated subjects per arm, an 
adequate number of subjects will need to meet the inclusion/exclusion criteria at screening.
If the interim analysis for futility and dose adaptation suggests that an additional dose arm (at a 
lower dose level) needs to be added, then up to 40 additional subjects may be randomized.
8.2
Populations for Analyses

All Enrolled Subjects, defined as all subjects who sign an informed consent;

All Randomized Subjects, defined as all subjects who are randomized to a treatment; 

All Treated Subjects, defined as all subjects who receive at least one dose of study treatment;

Biomarker Analysis Population, defined as all subjects that receive any study medication and 
have at least 1 post-treatment biomarker measurement. 

Pharmacokinetic Population, defined as all subjects who receive any study medication and 
have any available concentration-time data. 

Immunogenicity Population, defined as all subjects who receive study drug and have at least 
1 post treatment immunogenicity measurement.
All subjects who receive at least one dose of study treatment (all treated subjects) will be 
included in the safety analysis population and the efficacy analysis population. However, the 
subjects from Part 1 who are randomized to a treatment arm that is discontinued based on the 
Part 1 Safety/RO analysis will be excluded from the efficacy analysis. More details will be 
provided in the statistical analysis plan.

When at least 6 patients per treatment arm have either reached Study Day 29 or discontinued, an 
interim analysis (IA) for safety and RO will be performed. The safety analysis will focus on 
incidence and severity of all adverse events (AEs), serious AEs and pre-established Events of 
Special Interest such as infection AEs and any other safety analysis requested by DMC. For RO: 
the median RO at Day 29 for each treatment arm will be calculated. Based on the results of this 
interim analysis, a decision will be taken regarding the doses that will be carried forward into 
Part 2 of the study. Specifically, dosing regimens originally included in Part 1 may be 
discontinued and/or new dosing regimens may be added according to the following criteria:
2.0
Approved

v


Clinical Protocol
IM128027
BMS-931699
lulizumab pegol
Safety:
The DMC in conjunction with an unblinded internal monitoring team may require one or more 
doses to be discontinued if stopping criteria are met or other safety signals arise that the Medical 
Monitor and/or DMC consider of sufficient concern.
Receptor Occupancy:

If median RO of any dose is < 20%, the sponsor may consider dropping that dose

If the median RO for all doses is > 90% the sponsor may consider adding or replacing a dose 
in Part 2 of the study to ensure an adequate pharmacodynamic range (dose not to exceed 
12.5 mg weekly)
Dose decrease and/or reduction of frequency of administration may also be considered if RO 
results fall outside the parameters indicated above. This adjustment may occur for safety reasons 
or in case unforeseen RO profiles observed in SLE patients. The decision to adjust dose and/or 
frequency will be taken after review of the data by the clinical team.
8.6.2
Interim Analysis for Futility and Dose Adaption at Day 85
After 30 subjects per treatment arm (including the subjects from Part 1) have completed at least 
84 days of the treatment period or discontinued the treatment, an interim analysis will be 
conducted to assess the futility of the BMS-931699 dose arms and the overall safety. The results 
of the interim analysis will be reviewed by an unblinded sponsor team who will provide 
recommendations to the blinded study team. The blinded study team will make the decision. The 
unblinded BMS team may recommend to:

maintain the current design;

drop a certain dose arm(s) and equally randomize the remaining unallocated subjects to the 
remaining arms;

stop the study if all dose arms need to be dropped for safety or futility reasons.
The interim analysis for futility and dose adaption will be performed on the BICLA response at 
Day 85 of those 30 subjects per arm and BICLA response at Day 169 of those subjects who have 
completed 168 days of treatment or discontinued the treatment using a Bayesian predictive 
approach.22 This analysis assumes that the BICLA at Day 85 and at Day 169 in the subjects who 
have not yet been observed will be similar to what were observed for the subjects included at the 
interim analysis at Day 85 and Day 169, respectively. As such the unobserved data will be 
simulated from the predictive distribution conditional on the interim data and the prior 
distribution of the treatment difference (using a non-informative prior). Under the Bayesian 
framework, the posterior distribution of the treatment difference (BMS-931699 active dose –
Placebo) will be constructed to determine the predictive probability of a successful outcome 
(ie, reach statistical significance) at the planned end of the trial for each dose arm. Based on 
computer simulations of the operating characteristics of the study design, the futility threshold in 
this interim analysis is set to 0.2. For the comparison of interest, if the predictive probability of a

successful outcome at the planned end of the trial falls below 0.2, that BMS-931699 dose arm is 
deemed futile in terms of BICLA response. However, the final futility will also incorporate the 
results from SRI(4), ACR28 and some biomarkers (C3, C4, ANA and anti-dsDNA). 
The proposed stopping rules at the interim analysis, based on the futility assessment and the 
overall safety assessment, are as follows:

Rule 1: Drop the futile dose arm(s) and the dose arm cannot be dropped until the lower dose 
arm has been dropped.

Rule 2: Drop the dose arm(s) with safety issues identified;

Rule 3: If safety issues are identified in all dose arms or all dose arms are futile, stop the 
study.
In case dosing arms are dropped following the interim analysis, the remaining unallocated 
subjects will be randomized into the remaining arms.
If the predictive probability of success for each active arm versus placebo is greater than or equal 
to 0.9, then the BMS team may also recommend adding an additional dose arm at lower dose 
level than current active doses to explore the suboptimal dose.
In that case, the remaining un-allocated subjects with up to 40 additional subjects will be 
randomized into the remaining arms and the new dose arm based on the new randomizations 
schedule.

to obtaining IRB/IEC approval/favorable opinion, as soon as possible the deviation or change 
will be submitted to:

IRB/IEC for review and approval/favorable opinion

BMS

Regulatory Authority(ies), if required by local regulations
Documentation of approval signed by the chairperson or designee of the IRB(s)/IEC(s) 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/screening.
If the revision is done via an administrative letter, investigators must inform their IRB(s)/IEC(s).
9.1.2
Monitoring
BMS 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.
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. 
9.1.2.1
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.
9.2
Records
9.2.1
Records Retention
The investigator must retain all study records and source documents for the maximum period 
required by applicable regulations and guidelines, or institution procedures, or for the period 
specified by BMS, whichever is longer. The investigator must contact BMS prior to destroying 
any records associated with the study.
BMS will notify the investigator when the study records are no longer needed.
If the investigator withdraws from the study (eg, relocation, retirement), the records shall be 
transferred to a mutually agreed upon designee (eg, another investigator, IRB). Notice of such 
transfer will be given in writing to BMS.
9.2.2
Study Drug Records 
It is the responsibility of the investigator to ensure that a current disposition record of study drug 
(inventoried and dispensed) is maintained at the study site. Records or logs must comply with 
applicable regulations and guidelines and should include:

amount received and placed in storage area

amount currently in storage area

label identification number or batch number 

amount dispensed to and returned by each subject, including unique subject identifiers

amount transferred to another area/site for dispensing or storage

nonstudy disposition (eg, lost, wasted) 

amount destroyed at study site, if applicable

amount returned to BMS

retain samples for bioavailability/bioequivalence, if applicable

dates and initials of person responsible for Investigational Product dispensing/accountability, 
as per the Delegation of Authority Form.
BMS will provide forms to facilitate inventory control if the investigational site does not have an 
established system that meets these requirements.

Case Report Forms
An investigator is required to prepare and maintain adequate and accurate case histories designed 
to record all observations and other data pertinent to the investigation on each individual treated 
or entered as a control in the investigation. Data that are derived from source documents and 
reported on the CRF must be consistent with the source documents or the discrepancies must be 
explained. Additional clinical information may be collected and analyzed in an effort to enhance 
understanding of product safety. CRFs may be requested for AEs and/or laboratory abnormalities 
that are reported or identified during the course of the study.
For sites using the BMS electronic data capture tool, electronic CRFs will be prepared for all 
data collection fields except for fields specific to SAEs and pregnancy, which will be reported on 
the paper or electronic SAE form and Pregnancy Surveillance form, respectively. Spaces may be 
left blank only in those circumstances permitted by study-specific CRF completion guidelines 
provided by BMS.
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, including any paper or electronic 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 .For electronic CRFs, review 
and approval/signature is completed electronically through the BMS 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 BMS training requirements 
and must only access the BMS electronic data capture tool using the unique user account 
provided by BMS. User accounts are not to be shared or reassigned to other individuals.

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 patient. 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.
Medical Research
Those scientific activities which cannot be reasonably 
anticipated at the time of trial design, for which we would 
like to collect and/or retain samples from study participants. 
Examples of Medical Research include, but are not limited 
to, new assay development and validation, companion 
diagnostic development, new hypotheses in the interaction of 
drug and the human body, and exploration of emerging 
science in the understanding of disease.

Schedule of Analyses:
The following analyses will be performed:

An interim analysis for the safety/RO at Day 29 of Part 1 when at least 6 patients per 
treatment arm have either reached Study Day 29 or discontinued (refer to the details in 
Section 7.5.5);

An interim analysis for futility and dose adaptation will be performed when approximately
30 patients per treatment arm (including the patients from part 1) have completed at least 84 
days of treatment period or discontinued the treatment;

A final analysis will be performed after the last treated subject in the study reaches the end of 
the short-term period.

STUDY DESCRIPTION
2.1
Study Design
This is a Phase 2, parallel-arm, randomized, double-blinded, multicenter, international study, 
with an adaptive design. 
The study will comprise a short-term period (Part 1 and Part 2), and a long-term extension (LTE) 
period. This SAP covers the short-term period of the study.
Part 1 of the short-term period will focus on assessing safety and RO and will be limited to a 
maximum of 50 patients (approximately 6-10 patients/arm) who will be included in the 
Safety/RO interim analysis (IA). These patients will continue study treatment beyond the IA for 
Safety/RO and be treated for up to 24 weeks and be followed for 6 additional weeks after 
treatment is completed. Treatment could be shorter if IA for Safety/RO analysis indicates one or 
more arms should be dropped.
Part 2 of the short-term period will start once cumulative safety profile is considered acceptable 
and RO data for 6-10 subjects per cohort dosed for >28 days is available and the interim analysis 
from Part 1 is completed. Approximately 300 subjects will be randomized into this part of the 
study (number of patient to be randomized into Part 2 may increase based on the results of the 
futility interim analysis). 
All subjects will undergo screening evaluations to determine eligibility and allow down titration 
of prednisone (or prednisone equivalent) prior to administration of study medication. The 
screening period will have a duration of approximately 28 days (+/- 2 days). All eligibility 
criteria must be met prior to Day 1. In the event of technical difficulties leading inconclusive 
assessments that would go beyond the allowed window, the study medical monitor must be 
consulted prior to conducting Day 1. On Day 1, eligibility of subjects will be confirmed and 
eligible subjects will receive their first dose of study medication.

Dose may be adapted based on results of the planned interim analyses from Part 1 and Part 2, as 
follows:

Safety and RO interim analysis: safety and RO analysis will be performed when 
approximately 6 to 10 subjects per arm have reached Study Day 29. Based on the 
results of this analysis, dose arms(s) may be adjusted or may be dropped. 

Interim analysis for futility and dose adaptation on BICLA response, SRI 
response, ACR28 and some SLE biomarkers (such as auto-antibodies, 
complement levels, etc.) with possible exploratory exposure response analysis, 
will be performed when approximately 30 subjects per arm have reached Study 
Day 85 (12 weeks), including subjects from Part 1 and Part 2, of treatment or 
have discontinued prior to reaching study Day 85). Analysis will be performed by 
an unblinded Sponsor team, while maintaining blind at the site and subject level. 
Based on the results, the dose levels and sample size may be modified. 

Ongoing assessment of safety will be performed by an independent Data 
Monitoring Committee (DMC) and an internal unblinded safety monitoring team. 
Both entities may make recommendations to the Sponsor regarding conduct of 
study and dose adjustment based on safety observations.
Following interim analyses and DMC reviews, dose arm(s) may be modified based on the 
results, as follows:

If one or more arms are added, future randomizations will include the new arm(s). 

If one or more arms are dropped for safety reasons, randomization into that arm 
will be terminated and all subjects currently randomized to that or those arm(s) 
will be discontinued from receiving study medication.

If one or more arms are dropped due to inadequate RO, there will be no new 
randomizations into that dose arm; subjects currently randomized may continue at 
the Investigator discretion. 
The long-term extension (LTE) period is optional and will include eligible subjects who have 
completed Day 169 (week 24) of treatment and consent to participate. This period of the study 
will remain blinded but will no longer have a placebo arm. Eligible subjects will remain on their 
originally-assigned dose arm, unless they were on the placebo arm during the short-term period. 
Placebo-arm subjects will be re-randomized into one of the existing active arms at Day 169 
(24 weeks). Re-randomization of the placebo subjects will be done by IVRS and only the 
unblinded pharmacist/drug preparer will know the new randomization arm. The LTE will remain 
blinded to the study team and study personnel. 
The long-term extension period will not have interim analyses for dose adaptation. However, the 
BMS unblinded safety committee will continue to review the safety data and discuss it with the 
DMC (also unblinded), as needed. During their evaluation of adverse events, if a significant 
safety concern is identified, these two committees may propose that one or more dose arms are

Approximately 125 sites will participate in this study, which will be conducted globally and 
should include, but will not be limited to, participation of countries located in North America and 
Europe.
Subjects who discontinue from the study will have one follow-up visit, approximately 42 days 
(6 weeks) after receiving their last dose of study medication, to perform safety assessments. 
During this period, when subjects are no longer receiving study drug, it is recommended that 
they are not treated with other biologic therapy, due to the compound’s half-life. However, this 
decision remains at the investigator’s discretion. If the study drug becomes commercially 
available, and if the subject chooses to receive treatment with the commercial product, then the 
subsequent post-dose follow-up visits are not required.
For more details, refer to the study protocol.
2.2
Treatment Assignment
After completion of all screening evaluations and confirmation of eligibility, subjects will be 
randomized on Day 1 to one of the following dosing arms in a 1:1:1:1:1 ratio in Part 1 of the 
study design: BMS-931699 at 12.5mg weekly sub-cutaneous (SC) injection, BMS-931699 at 
12.5mg every other week (EOW) SC injection, BMS-931699 at 5mg EOW SC injection, BMS-
931699 at 1.25mg EOW SC injection, or Placebo SC injection. The randomization ratio and the 
treatment arms may be modified based on the results from the two interim analyses defined in 
Section 7.6. 
In this study, subjects will be randomized to receive one of the treatments according to a 
computer-generated randomization scheme prepared by a Randomization Coordinator within the 
Drug Supply Management Department of BMS Research and Development.
During the Screening visit, the investigative site will call into the enrollment option of the 
Interactive Voice Response System (IVRS) 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 sequential subject numbers starting with 00001, 00002, 00003.... 00010. The 
patient identification number (PID) will ultimately be comprised of the site number and subject 
number. For example, the first subject screened (i.e., enrolled) at site number 1, will have a PID 
of 0001 00001.Once it is determined that the subject meets the eligibility criteria following the 
Screening visit, the investigative site will call the IVRS to randomize the subject into the 
treatment period.
Every randomized subject will be required to come to the clinic/research center weekly to be 
dosed. This will ensure double-blind is maintained despite the variability of regimens. Subjects 
randomized to weekly subcutaneous injections of either placebo or BMS-931699 will be dosed 
weekly as per schedule and subjects randomized to one of the every other week arm will be 
alternating between receiving a subcutaneous injection of BMS-931699 one week and one of 
placebo the following week.

Blinding and Unblinding
2.3.1
Blinding at the Study Sites
The subjects and clinical assessor(s) will not be aware of which treatment is being administered 
to the subjects enrolled in the study. The pharmacist (or qualified drug preparation person) will 
be unblinded to study medication (BMS-931699 or placebo).
The pharmacist (or qualified drug preparation person) will know the randomization assignments 
and prepare the appropriate dose of active BMS-931699 or placebo accordingly. The prepared 
drug must be supplied to study personnel in a manner such that neither study personnel nor 
subjects will be aware of whether they receive active drug or placebo.
2.3.2
Unblinding of the Study Sites
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, i.e., 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 active product. It is highly desirable that the decision to unblind treatment assignment 
be discussed with the Medical Monitor, but the investigatory 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.
For information on how to unblind in an emergency, consult the IVRS manual.
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 non-emergency purposes should be discussed with the 
Medical Monitor.
In case of an emergency, the Investigator(s) has unrestricted access to randomization information 
via the Interactive Voice Response System (IVRS) and is capable of breaking the blind through 
the IVRS system without prior approval from sponsor. Following the unblinding the Investigator 
shall notify the Medical Monitor and/or Study Director.
2.3.3
Other Unblinding Information
For analysis of pharmacokinetic and anti-BMS-931699 samples, the Bioanalytical Sciences 
Group at BMS, and/or the designated vendor performing the analysis will be unblinded to the 
randomized treatment assignments in order to minimize unnecessary analysis of samples from 
control group subjects.

In collaboration with the DMC, an unblinded internal safety monitoring team, which is 
independent of the study team, will review the safety data throughout the study and will provide 
recommendations to the blinded study team. Therefore, the unblinded internal safety monitoring 
team can be unblinded. The unblinded internal safety monitoring team will have members from 
the Global Pharmacovigilance and Epidemiology group (GPV&E) within BMS.
The following BMS personnel will form the unblinded team (Independent of the blinded study 
team): one or more GPV&E physicians, one or more PK scientists, pharmacometrics analysts, 
one or more statisticians and programmers.

The Chi-square tests will be used to compare the BICLA response rates at Day 169 between each 
of the active treatment arms and the placebo arm. The Chi-square p-value will be provided for 
each comparison between the active treatment and the placebo arm. In addition, the difference of 
the response rates between each active treatment and the placebo arm will be estimated and their 
corresponding 90% confidence interval will be calculated. No adjustment will be made for 
multiplicity.
For each of the binary endpoints, the estimate and its corresponding 90% confidence interval will 
be calculated for the difference of the proportions between each active treatment arm and the 
placebo arm at the specified visit, similar to the primary analysis except no p-values will be 
provided.
The construction of confidence intervals for binary variables will be based on normal 
approximation if the number of the events in each individual treatment arm is at least 5. 
Otherwise, confidence interval using an exact method will be provided. The exact confidence 
intervals for binary variable within treatment group and between treatment groups will be 
constructed.
For each of the continuous endpoints, the mixed model will be fit with treatment, visit, and 
treatment-by-visit interaction as the fixed effects and measurements within each subject as the 
repeated measurements. The baseline value will be added into the model as a covariate if 
necessary. Based on the mixed model, the estimate and 90% confidence interval will be 
calculated for the difference between each active treatment and the placebo at each specified 
visit.
The results will be presented by the following grouping scheme in different periods, unless 
otherwise specified. 

Pre-treatment period: Only one group: All enrolled subjects.

Short-term period (ST): The results will be presented by treatment groups.

deviations will be listed and summarized by treatment group. The subjects identified as relevant 
protocol deviation will not be excluded from any analysis population described in Section 6.3. If 
at least 10% of total subjects in all treatment arms in the efficacy analysis population 
demonstrate relevant protocol deviations, a per-protocol analysis may be performed.
7.3
Study Population
Frequency distributions or summary statistics of data pertaining to subject disposition, 
demographic characteristics, baseline disease characteristics, and medical history will be 
tabulated and displayed by treatment group.  No statistical test will be carried out for comparison 
of any baseline measures among treatment groups.

population, unless specified otherwise. 
7.3.1
Subject Disposition
The number of subjects enrolled into the study at screening, the number of subjects randomized, 
the number of subjects entering the short-term period (ST) and the number of subjects who 
complete the ST period will be summarized by treatment groups. The number of subjects
discontinuing from the ST period (subject disposition) will also be summarized, together with 
the reasons for discontinuation, taken from the CRF status pages. The subject disposition for the 
ST period will be based on the MITT analysis population.

Medical history and prior medication information before the first study medication will be 
summarized by treatment group using relative frequencies. Listings of medical history and prior 
medication will be presented. The results will be based on the MITT analysis population.
7.4
Extent of Exposure
7.4.1
Study Therapy
In general, extent of exposure during ST will be summarized for the As-treated analysis 
population in two ways: 

by the number of study drug injections: Frequency distribution of number of 
injections will be summarized

by the number of days: the subject is known to be on study drug, ignoring any 
dosing interruptions
In general, exposure to study drug during the short-term period (ST) is calculated as follows: 
1. The subjects who enter in the long-term extension period (LTE) within 7 days 
of the last study medication in ST,
Exposure (in days) = (date of first study medication in LTE - date of first study 
medication in ST).
2. All other subjects (including the subjects who discontinue early, complete the 
ST but do not enter in the LTE or enter LTE after 7 days post the last dose of 
the ST):
Exposure (in days) = date of last study medication in ST - date of first study 
medication in ST + 7
Note that, the offset of 7 days represents the dosing interval of 7 days.

Discontinuations from Study Therapy
Discontinuation from study therapy is defined as subject’s termination of the study medication 
without resumption prior to study completion. Note that, subjects are to be discontinued if more 
than 3 consecutive doses of study medication are missed. Discontinuation from study therapy 
during the ST period will be summarized by reason for the premature termination, taken from the 
study status case report form (CRF) pages. These summaries will be provided based on the 
MITT analysis population by randomized treatment group and overall.
7.4.3
Treatment Compliance
The CRF for this study will capture information on injections of the study medication. All 
subjects who skip any study drug injection will be listed. The number of subjects with missed 
injections (excluding missed injections due to premature discontinuation from the study) by 
number of missed injections will be summarized based on the As-treated analysis population for 
the ST period by treatment groups.
 
7.4.5
Immunosuppressant  Medication
For the purpose of this analysis plan, the term DMARDs will refer to non-biologic DMARDs. 
Immunosuppressant medications summaries will be provided to present the medication use of 
corticosteroids, NSAIDs, and DMARDs. Number and percent of subjects receiving 
corticosteroids, NSAIDs, and DMARDs will be summarized by treatment group for MITT

7.5.1
Primary Efficacy Endpoints in the Short-term Period
The primary efficacy endpoint is BICLA response rate at Day 169.
The Chi-square tests will be used to compare the BICLA response rates at Day 169 between each 
of the active treatment arms and the placebo arm. The Chi-square p-value will be provided for 
each comparison between the active treatment and the placebo arm. No adjustment will be made 
for multiplicity. In addition, the difference of the response rates between each active treatment 
and the placebo will be estimated and their corresponding 90% confidence interval will be 
calculated for Day 169 visit and other applicable visits. 
The point estimate for BICLA response rate along with 90% confidence interval will be 
calculated for each treatment arm for each applicable visit.
All subjects who prematurely discontinue the trial after receiving study medication will have
missing data imputed as non-responder at all scheduled protocol visits subsequent to the point of
discontinuation. The analysis will be performed based on Efficacy Analysis Population. More
details of imputation rule for classification of binary response status are provided in Sections 8.3,
8.1.1, and 8.1.2.
For BICLA, the number of responders, together with the rescue status (with or without one-time 
rescue allowed per protocol) will be summarized by treatment group. At the same time, the 
number of nonresponders will be summarized by treatment group, together with the reasons for 
nonresponse.
7.5.2
Secondary Efficacy Endpoints in the Short-term Period
For each of the binary endpoints (SRI(X) etc.), the estimate and its corresponding 90% 
confidence interval will be calculated for the difference of the proportions between each active 
treatment arm and the placebo arm for each applicable visit, similar to the primary analysis 
except no p-values will be provided.
For each of the continuous endpoints (BILAG-2004, SLEDAI, MDGA, CLASI, etc.), the mixed 
model will be fit with treatment, visit, and treatment-by-visit interaction as the fixed effects and 
measurements within each subject as the repeated measurements. The baseline value will be 
added into the model as a covariate if necessary. Based on the mixed model, the estimate and 
90% confidence interval will be calculated for the difference between each active treatment and 
the placebo at each specified visit. No p-values will be provided. In addition, Descriptive 
summary statistics of mean change from baseline and 90% confidence interval for each treatment 
arm will be provided. The missing data in continuous measures will be handled via utilization of 
mixed model procedure in SAS.
7.5.3
Subgroup Analyses
The subgroup analyses of the primary and selected secondary endpoints ((SRI (X): X = 4, 6.)) 
will be performed within the following predefined subgroup (Non-Japan subjects). If the value of

the grouping variable cannot be determined for a subject, the subject will be excluded from the 
corresponding subgroup analysis. 
In addition, other subgroup analyses may be performed on primary and selected secondary 
endpoints as post-hoc analysis. 
7.5.4
Sensitivity Analyses
Sensitivity analysis for the primary endpoint: Adjustment for the randomization strata using 
Cochran-Mantel-Haenszel (CMH) methods will be applied on the primary endpoint. 
If at least 15-20% of total subjects through all treatment arms in the efficacy analysis population 
discontinued due to any reasons other than Lack of Efficacy (LOE), AE or Unknown reason, a 
sensitivity analysis may be performed. The subjects who have missing response due to premature 
discontinuation with reasons other than LOE, AE or Unknown will be excluded from the 
analyses, hence defining the sensitivity analysis population. The sensitivity analysis will be 
carried out for the primary and selected secondary endpoints (SRI (X): X = 4, 6.) based on the 
sensitivity analysis population.
7.5.5
Per-Protocol (PP) Analyses
If at least 10% of total subjects in all treatment arms in the efficacy analysis population 
demonstrate relevant protocol deviations, a per-protocol analysis may be performed. A per-
protocol analysis will be carried out for the primary and selected secondary endpoints (SRI (X): 
X = 4, 6.) based on the per-protocol (PP) analysis population. A Per-protocol (PP) analysis 
population will exclude all subjects with at least one relevant protocol deviation (defined in 
Appendix 1) from the efficacy analysis population based on the following rules.

The subjects satisfying eligibility criteria deviation in Appendix 1 will be excluded from the 
PP analysis population completely. 

The subjects satisfying incorrect dosing criteria deviation in Appendix 1 will be excluded 
from the PP analysis population partially (only the data after deviation occurs will be 
excluded from the per-protocol (PP) analysis.)
7.6
Safety
Analysis of all safety data will follow the BMS standard safety data conventions4 5 and 
supplements to the standard conventions as defined in this document.
The evaluation of drug safety is based primarily on clinical AE, laboratory abnormalities and 
vital signs reported during the study.
The summaries of AEs and laboratory marked abnormality during the ST period will be provided 
by treatment groups. AEs and laboratory marked abnormalities will be included in the summary 
tables based on ST period if the onset date is on or after the first dose date and event occurs

within the ST period for continuing subjects or within 42 days post last dose date for 
discontinued subjects.
Frequency distribution and individual listings of all AEs will be generated. Laboratory marked 
abnormality using pre-defined abnormality criteria will also be descriptively summarized. There 
will be no statistical testing of group difference with respect to frequencies of AEs or laboratory 
marked abnormalities.
All recorded adverse events will be listed and tabulated by system organ class, preferred term, 
treatment and overall. Any physical examination findings will be listed. ECG, vital signs and 
clinical laboratory test results and corresponding change from baseline values will be listed and 
summarized by treatment. Values for ECG, vital signs and clinical laboratory test results outside 
the pre-specified criteria will also be listed and summarized. ECG readings will be evaluated by 
the Investigator and abnormalities, if present, will be listed.  
Unless otherwise specified, baseline is defined as the last non-missing result with a collection 
date-time less than the date-time of the first dose of study medication, for laboratory results, vital 
signs and ECG.
Presentations for the ST period will be provided by “as treated” treatment group for the as-
treated analysis population, unless otherwise specified.
7.6.1
Adverse Events
The investigator will determine the intensity of each AE as mild, moderate, severe, or very 
severe. In addition, the investigator will determine the relationship of the AE to the 
administration of the study drug.
All AEs are coded and grouped into Preferred Terms (PT) by System Organ Class (SOC), using 
the latest approved version of the Medical Dictionary for Regulatory Activities (MedDRA) at the 
time of database lock.  Listings and summaries will be based on the resulting SOCs and PTs.
AEs will be included in the frequency tabulations if they occur while a subject is on study 
medication up to and including 42 days after the last dose of study medication. These AE 
summaries will be based on proportions, which represent the number of subjects experiencing 
the AEs divided by the number of subjects received with at least 1 dose of study medication in 
the current period.
All AE listings will indicate the unique subject identifier, age, gender, current treatment, the date 
of onset, the date of resolution, day of onset relative to the start of treatment, action taken, 
investigator’s assessment of severity and relationship to study drug. Additional listings will be 
provided for adverse events leading to discontinuation and adverse events without recorded 
resolution. Summaries of adverse events will include adverse events, adverse events by intensity 
and adverse events by relationship.  
Where a subject has the same adverse event, based on preferred terminology, reported multiple 
times in a single analysis period, the subject will only be counted once at the preferred 
terminology level in adverse event frequency tables.

analysis period, the subject will only be counted once at the system organ class level in adverse 
event frequency tables.
When a subject has the same adverse event, based on preferred terminology, reported multiple 
times in a single analysis period, the following criteria, in order of precedence, will be used to 
select the event to be included in summary tables:

Relationship to study medication

Intensity of event

Onset date and time
When reporting adverse events by intensity, in addition to providing a summary table based on 
the event selection criteria detailed above, summary tables will also be provided based on the 
most intense event during the analysis period - independent of relationship to study medication. 
For these tables, the following criteria, in order of precedence, will be used to select the event to 
be included in summary tables:

Intensity of event

Onset date and time
Subjects will only be counted once in the ‘Total’ at their maximum intensity, regardless of SOC 
or PT.
Any reported AEs that occur more than 42 days after the last dose of study drug will be excluded 
from safety summaries. Any reported AEs that occur more than 42 days post the last dose of 
study drug will appear in the listing. 
Summary information (the number and percent of subjects by treatment) will be tabulated for the 
following AEs: 

All AEs including clinical and laboratory AEs

Most common AEs (reported in 5% of subjects or more in any treatment 
group)

All related events

Serious AEs (SAEs)

Discontinuations due to AEs
Laboratory AEs are laboratory changes identified by the investigator as AEs and thus reported on 
the AE pages of the eCRF.

Interim Analyses
7.10.1
Interim Safety/RO Analysis at Day 29
When at least 6 patients per treatment arm have either reached Study Day 29 or discontinued, an 
interim analysis (IA) for safety and RO will be performed. The safety analysis will focus on 
incidence and severity of all adverse events (AEs), serious AEs and pre-established Events of 
Special Interest such as infection AEs and any other safety analysis requested by DMC. A 
separate document, DMC charter, describes the scope of these analyses. For RO: the median RO 
at Day 29 for each treatment arm will be calculated. Based on the results of this interim analysis, 
a decision will be taken regarding the doses that will be carried forward into Part 2 of the study. 
Specifically, dosing regimens originally included in Part 1 may be discontinued and/or new 
dosing regimens may be added according to the following criteria:
Safety:
The DMC in conjunction with an unblinded internal monitoring team (The details of the 
members are provided in Section 2.3.2) may require one or more doses to be discontinued if 
stopping criteria are met or other safety signals arise that the Medical Monitor and/or DMC 
consider of sufficient concern.
Receptor Occupancy:

If median RO of any dose is <20%, the sponsor may consider dropping that 
dose

If the median RO for all doses is >90% the sponsor may consider adding or 
replacing a dose in Part 2 of the study to ensure an adequate 
pharmacodynamic range (dose not to exceed 12.5 mg weekly)
Dose decrease and/or reduction of frequency of administration may also be considered if RO 
results fall outside the parameters indicated above. This adjustment may occur for safety reasons 
or in case unforeseen RO profiles observed in SLE patients. The decision to adjust dose and/or 
frequency will be taken after review of the data by the clinical team. Any decision related to 
safety reasons will be taken in conjunction with DMC recommendations.
RO analysis in interim analyses 1 will be done by a Pharmacokinetic scientist or a 
Pharmacometrics analyst. If dose/doses are adjusted based on this RO analysis, then the interim 
analyses results may be included in CSR as an appendix.

Interim Analysis for Futility and Dose Adaptation at Day 85
After 30 subjects per treatment arm (including the subjects from Part 1) have completed at least 
84 days of the treatment period or discontinued the treatment, an interim analysis will be 
conducted to assess the futility of the BMS-931699 dose arms and the overall safety. The results 
of the interim analysis will be reviewed by an unblinded sponsor team (Independent of the study 
team) who will provide recommendations to the blinded study team. The details of the members 
are provided in Section 2.3.2. The blinded study team will make the decision. The unblinded 
BMS team may recommend to:

maintain the current design;

drop a certain dose arm(s) and equally randomize the remaining unallocated 
subjects to the remaining arms;

stop the study if all dose arms need to be dropped for safety or futility reasons.
Any decision related to safety reasons will be taken in conjunction with DMC recommendations.
The interim analysis for futility and dose adaption will be performed on the BICLA response at 
Day 85 of those 30 subjects per arm and BICLA response at Day 169 of those subjects who have 
completed 168 days of treatment or discontinued the treatment using a Bayesian predictive 
approach.6 This analysis assumes that the BICLA at Day 85 and at Day 169 in the subjects who 
have not yet been observed will be similar to what were observed for the subjects included at the 
interim analysis at Day 85 and Day 169, respectively. As such the unobserved data will be 
simulated from the predictive distribution conditional on the interim data and the prior 
distribution of the treatment difference (using a non-informative prior). Under the Bayesian 
framework, the posterior distribution of the treatment difference (BMS-931699 active dose –
Placebo) will be constructed to determine the predictive probability of a successful outcome 
(i.e., reach statistical significance) at the planned end of the trial for each dose arm. Based on 
computer simulations of the operating characteristics of the study design, the futility threshold in 
this interim analysis is set to 0.2. For the comparison of interest, if the predictive probability of a 
successful outcome at the planned end of the trial falls below 0.2, that BMS-931699 dose arm is 
deemed futile in terms of BICLA response. However, the final futility will also incorporate the 
results from the efficacy endpoints such as but not limited to SRI(4), ACR28 and some 
biomarkers such as but not limited to C3, C4, ANA and anti-dsDNA. The final decisions will be 
made based on the discussions using the pre-specified rules in the Interim Analysis SAP and/or
the evidence from the totality of the data.
The proposed stopping rules at the interim analysis, based on the futility assessment and the 
overall safety assessment, are as follows:

Rule 1: Drop the futile dose arm(s) and the dose arm cannot be dropped until 
the lower dose arm has been dropped.

Rule 2: Drop the dose arm(s) with safety issues identified;


Rule 3: If safety issues are identified in all dose arms or all dose arms are 
futile, stop the study.
In case dosing arms are dropped following the interim analysis, the remaining unallocated 
subjects will be randomized into the remaining arms.
If the predictive probability of success for each active arm versus placebo is greater than or equal 
to 0.9, then the BMS team may also recommend adding an additional dose arm at lower dose 
level than current active doses to explore the suboptimal dose.
In that case, the remaining un-allocated subjects with up to 40 additional subjects will be 
randomized into the remaining arms and the new dose arm based on the new randomizations 
schedule.
A separate document, Interim Analysis SAP, has been developed in order to provide a set of rules
with clarifying details as a guidance to make any decisions about the dose adaptation.

Time to event Analysis
Time to treatment failure and time to first flare as assessed by new BILAG 2004 index flare 
definition will be summarized. For those time to event endpoints, if necessary, the point estimate 
and its 90% confidence interval for the hazard ratio of each active treatment arm versus placebo 
will be calculated based on the Cox proportional hazards models. In addition, the distribution of 
time to the occurrence of event will be estimated using Kaplan-Meier method. The analysis will 
be based on the Efficacy Analysis Population.
Treatment failure is defined as non-protocol treatment i.e., new or increased immunosuppressive 
treatment or antimalarials; or parenteral corticosteroids; or protocol prohibited dose of oral 
corticosteroid; or premature discontinuation from study treatment.

Analysis for the PK Sub-Study
As specified in the amendment 9 of the protocol, participation for PK sub-study is voluntary. 
While there is no minimum required number of subjects, every effort will be made to enroll 
approximately 4 subjects/arm in the ST study (ie approximately 20 subjects total) and 
approximately 6 subjects/arm in the LTE (ie approximately 30 subjects total). This sample size is 
expected to provide sufficient data to adequately estimate PK parameters for lulizumab in this 
patient population. Subjects will be asked to read, understand, and sign an informed consent 
form designed for the purpose of collecting the additional PK/RO samples.

Evaluation of BICLA response
BICLA response is defined based on the following components:

British Isle Lupus Assessment Group improvement, defined as BILAG ‘A’s at 
Baseline improved to ‘B’/’C’/’D’, and BILAG ‘B’s at baseline improved to 
‘C’/’D’, and no BILAG worsening in other BILAG organ systems such that 
there are no new BILAG ‘A’s or greater than 1 new BILAG ‘B’; and,

No worsening in the SLEDAI-2K total score compared to Baseline (defined as 
no increase in SLEDAI total score); and,

No worsening in the physician’s global assessment (MDGA) of disease 
activity (“no worsening” is defined as less than 10% worsening, equivalent to 
a 10mm increase on a 100mm visual analog scale [VAS]) compared to 
Baseline; and,

No changes in concomitant medications according to the following criteria: 

No increase of or addition of a new immunosuppressant agent 
(azathioprine, methotrexate, anti-malarial) over baseline levels


No increase in corticosteroid dose above baseline level outside of those 
allowed per protocol.
If a subject failed any of the above criteria above, the BICLA response status of the subjects will 
be set to non-responder.
For the determination of missing BICLA response status, all subjects who prematurely 
discontinue from the study medication will be imputed as non-responder at all scheduled efficacy
visits subsequent to the point of discontinuation.
If any subject has at most one missing component (e.g. MDGA for BICLA) at a given efficacy
visit not due to premature discontinuation, the component-wise response status will be imputed 
based on the following rules.

If the given visit is not the last scheduled efficacy visit (Day 169), imputation will depend 
on the observed responses from the immediate previous efficacy visit and the immediate 
next efficacy visit within 28 days of the current visit date. 

If the given visit is the last scheduled efficacy visit (Day 169), the imputation will depend 
on the observed responses at the previous 2 consecutive efficacy visits (within 56 days). 

If a subject has response (at component level) at both efficacy visits, the missing response 
status at current visit will be imputed as responder. Otherwise, response status will be set 
to non-responder.
The BICLA response status (composite) for a subject who has more than one component (e.g.
MDGA and SLEDAI-2K are missing for BICLA) missing at a given efficacy visit not due to 
premature discontinuation will be imputed as non-responder. 
After any imputation above or none, if for some reason the BICLA response status still cannot be 
determined, including the case where baseline data is missing, then its value will be set to non-
responder.
8.1.2
Evaluation of SRI(X)
In addition to BICLA, a novel endpoint, the SLE Responder Index [SRI] with a modification
used as a primary endpoint in the Anifrolumab study, the results of which were presented and 
published as an abstract at the American College of Rheumatology (ACR) National Meeting in 
November, 20157. The basic difference between the SRI defined in our protocol and the SRI in 
the Anifrolumab study is the addition of a fourth component of the endpoint. The original 
definition of SRI in the protocol does not include the fourth component based on the use of 
restricted medications.
The use of restricted medications is an important confounding factor when we analyze the 
endpoints such as BICLA, and SRI(X). Hence an additional component based on the use of 
restricted medications (same as the 4th component in the definition of BICLA) is deemed 
necessary to incorporate into the original definition of SRI (X) in the protocol. The modification 
to the existing definition of SRI is described below.

An SRI(X) [X= 4, 5, 6, and 8] response @ Day T (e.g. T = 85, 169) is defined as:

a reduction in Day 1 SLEDAI-2K disease activity score of ≥ X points at 
Day T; and,

no worsening of disease (defined as an increase of ≥ 10mm on a 100mm 
VAS from Day 1 as measured by the MDGA up to time T; and,

no new BILAG-2004 Index ‘A’ organ system score and no more than one 
new or worsening BILAG-2004 Index ‘B’ organ system scores up to time 
T ; and, 

No changes in concomitant medications according to the following 
criteria: 
o
No increase of or addition of a new immunosuppressant agent (azathioprine, 
methotrexate, anti-malarial) over baseline levels 
o
No increase in corticosteroid dose above baseline level outside of those allowed 
per protocol.
If a subject failed any of the above criteria, the SRI(X) response status of the subjects will be set 
to non-responder. 
For the determination of missing SRI(X) response status, all subjects who prematurely 
discontinue from the study medication will be imputed as a non-responder at all scheduled 
efficacy visits subsequent to the point of discontinuation. 
If any subject has at most one missing component (e.g. MDGA for SRI(X)) at a given efficacy
visit not due to premature discontinuation, the component-wise response status will be imputed 
based on the following rules.

If the given visit is not the last scheduled efficacy visit (Day 169), imputation will depend 
on the observed responses from the immediate previous efficacy visit and the immediate 
next efficacy visit within 28 days of the current visit date. 

If the given visit is the last scheduled efficacy visit (Day 169), the imputation will depend 
on the observed responses at the previous 2 consecutive efficacy visits (within 56 days). 

If a subject has response (at component level) at both efficacy visits, the missing response 
status at current visit will be imputed as responder. Otherwise, response status will be set 
to non-responder.
The SRI(X) response status (composite) for a subject who has more than one component (e.g.
MDGA and SLEDAI-2K are missing for SRI(X)) missing at a given (efficacy) visit not due to 
premature discontinuation will be imputed as non-responder. 
After any imputation above or none, if for some reason the SRI(X) response status still cannot be 
determined, including the case where baseline data is missing, then its value will be set to non-
responder.
Note that, the corrected threshold is 10mm in the second component of SRI(X) instead of 30mm 
(as in the original protocol) on a 100mm VAS of MDGA. The correct threshold is used in the 
definition of SRI(X) in this section.

Evaluation of SF-36 Summary Functions and Components
The SF-36 is composed of 36 items measuring 8 health concepts: Physical Functioning, Role-
physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-emotional, and Mental 
Health. These 8 scales form 2 summary scores: (1) Physical Component Summary (PCS) and (2) 
Mental Component Summary (MCS).  Scoring conventions for the SF-36 scales and components 
are documented in “SF Health Outcomes TM Scoring Software User’s Guide”8.
8.2
Baseline Measures
The baseline value is the last assessment taken prior to the first dose of study medication. In 
general, the baseline value is the assessment taken on study Day 1 before the administration of 
study medication unless otherwise specified.

If a measurement on Day 1 (baseline) is missing, the last assessment taken at the screening 
period prior to the first dose of study medication will be used.
8.3
Missing Measurements
For listings of binary response efficacy variables, missing values will be presented as missing.  
For determination of binary response variables, handling of missing values for BICLA and 
SRI(X) responses is addressed in Sections 8.1.1 and 8.1.2 unless otherwise specified.
If the response cannot be assessed due to missing data or a subject’s early discontinuation, the 
following conventions will be implemented in a sequence:

Any subject who prematurely discontinues the trial during the Short-term 
period after receiving study medication will have data imputed as non-
responder at all scheduled protocol visits subsequent to the point of 
discontinuation up to the end of the Short-term period.

After any imputation above or none, if for some reason the binary variable 
still cannot be determined, including the case where baseline data is missing, 
then its value will be set to non-responder.
For the analysis of continuous efficacy variables, mixed model will be used based on assumption 
of data being missing at random. Subjects with only baseline observations will be excluded from 
any changes from baseline analyses.
For safety, PK and immunogenicity measures and biomarkers, missing values will not be 
imputed.
8.4
Missing, Unknown or Partial Dates
The BMS safety guidelines for conventions relating to the handling of missing or partial dates 
and the determination of appropriate default values in such cases (in particular, for concomitant 
medication dose start-dates and end-dates and AE onset dates) will be utilized.  
8.5
Day Ranges for Analysis of Time Points
Subjects who do not always adhere strictly to the visit schedule timing in the protocol. Therefore 
the designation of visits during the Short-term period of the study will be based on the day of 
evaluation relative to the trial (day of first study medication = study Day 1) rather than the 
nominal visit recorded in the eCRF. Mutually exclusive relative day windows are defined below 
to provide derived visits that correspond to the post-baseline time points. If a visit falls outside of 
the pre-specified visit windows, then the data collected at that visit will not be assigned a derived 
visit but will remain in the derived data sets. Determination of baseline values is addressed in 
Section 8.2.
If a subject has more than 1 visit where a measurement is recorded within a window, the 
measurement closest to the target day will be used.  In case of 2 visits being equidistant from the 
target, the later measurement will be used in analyses. Exceptions to these rules apply to 
immunogenicity where the least favorable value (toward a positive response) in the window will 
be used.

For subjects who discontinue from study therapy prematurely, assessments performed after the 
last dose of the study drug will be included in the efficacy datasets provided that these 
assessments are made within 28 days of the last dose. 
Designation of visits for efficacy assessments, immunogenicity samples and receptor occupancy 
samples during the Short-term period is tabulated below.
