SYNOPSIS
Clinical Protocol IM140103
Protocol Title: Open Label, Adaptive Design, Ascending, Multiple-Dose Study to Evaluate Safety and Efficacy of 
BMS-986004 in Adult Subjects with Primary Immune Thrombocytopenia (ITP)
Investigational Product(s), Dose and Mode of Administration, Duration of Treatment with Investigational 
Product(s):  Total of 40 subjects will be enrolled for the study, treated in dose panels of 10 subjects each. Four (4) 
dose panels are planned to be enrolled sequentially in an ascending manner, with dose intensity selected to provide 
increased levels of immunosuppression at steady state. Dose levels that are planned to be evaluated in this trial are 
expected to elicit a range of clinical response. Based on current preclinical projections, the doses range from 75 mg 
to 1500 mg every two weeks. 
BMS-986004 will be administered once every 2 weeks as an IV infusion for a total of 7 doses. Subjects will receive 
investigational product on Day 1/Week 0, Week 2, Week 4, Week 6, Week 8, Week 10 and Week 12, for a total of 7 
doses. 
During the long term extension (LTE) period, BMS-986004 will be administered once every 2 weeks as an IV 
infusion for 24 weeks and during 2 Taper visits.
Study Phase: Phase 1b/2
Research Hypothesis: Because current study is an open label trial without placebo control, there is no formal 
research hypothesis to be statistically validated. The purpose of this study is to test if BMS-986004 will be effective 
in normalizing platelet counts in subjects with ITP, as well as to assess the safety, PK and immunogenicity of 
multiple doses of BMS-986004 in ITP subjects.
Primary Objectives:

To assess the overall safety and tolerability of multiple doses of BMS-986004, when administered in subjects 
with chronic ITP.
Secondary objectives: 

To evaluate efficacy of BMS-986004 in the treatment of thrombocytopenia in subjects with chronic ITP, as 
measured by platelet response/complete response (R/CR) and other clinical parameters. 

To establish BMS-986004 dose response, as measured by platelet count and other clinical parameters.

To measure the target engagement of BMS-986004 following multiple IV doses

To assess the effect of BMS-986004 on markers associated with the risk of thromboembolism (TE) in the 
multiple dose setting

To assess pharmacokinetics and immunogenicity of multiple doses of BMS-986004 in subjects with chronic 
ITP

Long Term Extension Period Objective:
To assess the long term clinical safety, tolerability and efficacy of BMS-986004. 
Study Design:  This is a Phase 1b/2, multicenter, open-label study to evaluate the safety, efficacy, dose response, 
and pharmacology (PK, target engagement and PD) of BMS-986004 in subjects with ITP. 
The study will comprise a short-term period and a long-term extension (LTE) period. 
The short-term period, is divided into three phases: Response Phase (6 weeks), Remission Phase (6 weeks) and 
Follow Up phase (8 weeks).
Screening evaluations to determine subject eligibility will be performed 21 days prior to study drug administration. 
The screening period may exceed 21 days but not more than 42 days total only after a discussion with and approval 
by the Study Director. If an extension in screening time is granted, the patient must still follow the platelet count 
rules for enrollment. The baseline platelet count determining enrollment eligibility will be based on the mean of two 
determinations taken within a week before the first dose. To be eligible for enrollment, platelet count needs to be 
less than 30,000/ mm3 and show stable or declining trend. If the mean platelet count is between 30,000 - 35,000/ 
mm3 the subject may be considered for enrollment on a case by case basis after discussion with and approval by the 
Study Director.
Following screening, a total of 40 evaluable subjects are planned for the study. Subjects are considered evaluable if 
they receive the first 4 doses of study drug and complete the required safety and efficacy evaluations at Day 50. 
Non-evaluable subjects will be replaced to maintain a count of 10 subjects in each dose panels, except subjects will 
not be replaced if they are discontinued from the study secondary to an adverse event unless the adverse event can 
be determined to be unrelated to treatment.
Subjects are treated in dose panels of 10 subjects each. Four (4) dose panels are planned to be enrolled sequentially 
in an ascending manner, with dose intensity selected to provide increased levels of immunosuppression at steady 
state. Dose levels (range from 75 mg to 1500 mg administered every two weeks) that are planned to be evaluated in 
this trial are expected to elicit a range of clinical response. 
BMS-986004 will be administered once every 2 weeks as an IV infusion for a total of 7 doses. Four (4) doses will be 
administered during the Response Phase over a 6 week treatment period. The remaining 3 doses will be 
administered during the Remission Phase of the study over a 6 week treatment period. Subjects will receive 
investigational product on Day 1/Week 0, Week 2, Week 4, Week 6, Week 8, Week 10 and Week 12, for a total of 7 
doses. 
Each dose cohort will enroll 10 new subjects, starting with the respective dose level at Day1/Week 0, regardless of 
the number of subjects joining a dose cohort because of intra-subject dose escalation. 
A new cohort may be opened to treat subjects at a dose lower than 75 mg if at least 6 subjects treated at the 75 mg 
cohort achieve platelet Response (R) (platelet count ≥ 30,000/mm3 and at least 2-fold increase from the baseline
count and absence of bleeding), at the end of response phase (Week 6). The new cohort would follow the same 
schedule as the other cohorts including intra-subject dose escalation.
The Long-term extension (LTE) period is optional and will include eligible subjects (defined as subjects from 
either cohort 3 or cohort 4 who complete 12 weeks (85-days) of treatment and who achieve a response as defined by 
at least a doubling of platelets from Short Term Day 1 baseline and a platelet count of ≥ 35,000/mm3. If a subject 
has platelet counts close to a doubling of platelets and/or between 30,000-35,000 platelets/mm3, the subject may be 
considered for the long term extension on a case by case basis, which will involve a review of data from the short 
term period and which will require approval by the Study Director.
Intra-subject dose escalation
Intra-subject dose escalation could occur after the subject has completed the Response Phase of the study. Subject 
will receive the next higher dose of BMS-986004 if clinically significant response has not been achieved based on 
measurement of platelet count on the last two consecutive counts performed at Day 43 and Day 50, and a favorable

safety profile is observed. Clinically significant response is defined as achieving platelet count ≥ 50,000/mm3 with 
an increase of at least 20,000/mm3 from baseline and absence of bleeding. Subject will then be dosed at the higher 
dose level for the remainder of the study (Remission Phase).
Dose frequency adjustment for responders exceeding 450,000/mm3 (for non-splenectomized subjects) and 
600,000/mm3(for splenectomized subjects) platelet count
For both the short-term period and the long-term extension, in the event that platelet count exceeds 450,000/mm3 for 
non-splenectomized subjects and 600,000/mm3 for subjects who underwent splenectomy, in the absence of recent 
(administered within two weeks) rescue medication, as indicated by the two consecutive platelet count 
measurements, dosing of the BMS-986004 should be stopped. Subject will remain in the study and platelet counts 
will be then assessed based on the normal study visit schedule. Dosing of BMS-986004 could be reinitiated only 
after discussion between Study Director and Investigator if clinically appropriate and dictated by the medical 
judgment and subject’s safety.
Dose escalation for dose panel and stopping rules
Decisions regarding dose escalation will be made based on the review of all cumulative safety information which 
includes, in general, the safety data through study Day 15 from the 10 subjects in the preceding lower dose cohort. If 
neither of the below stopping rules is present in dose panel, then dose escalation may proceed within the next higher 
dose level. However, escalation to the next higher cohort may occur when none of the stopping rules have been met 
and no less than 5 subjects in a cohort have been followed for at least 2 weeks under certain conditions as illustrated 
in the section of early decision of dose escalation for dose panel.
The stopping rules listed below will be used to determine whether it is safe to escalate to the next higher cohort. 
Dose escalation to the next planned dose will not proceed if any of the following criteria are met (Adverse event 
grading as defined by the Common Terminology Criteria for Adverse Events [CTCAE, Version 4.0]):

Five or more subjects in a cohort have platelet counts >450,000/mm3 for non-splenectomized subjects and 
>600,000/mm3 for subjects who underwent splenectomy, and platelet count raise is not attributable to a rescue 
or concomitant therapy.

Two or more subjects have serious adverse events in the same organ system (Grade 3 and above), that are 
determined to be related to study medication

It is determined that the limit of safety and/or tolerability has been reached. This decision will be made 
following discussions between the Study Team and the Investigator
If any of the above criteria are met within a dose level, the progression to a higher dose level will be put on hold and 
all safety data available across the study will be evaluated to estimate the risk of proceeding to the higher dose level. 
The review will include all of the subject(s) that experienced SAEs listed above. In addition, data set may include 
subjects from a dose panel, the entire dose panel, or if appropriate, all randomized subjects treated to date. 
In addition, decision may be made following discussions between the Study Team and the Investigator to halt dose 
escalation for reasons not defined above, including but not limited to, observing a single serious adverse event in 
individual subjects, observing trends in a given dose panel and across dose panels, and/or it is determined that the 
limit of safety and/or tolerability has been reached. 
If dose escalation is stopped due to any of these findings, additional cohorts may receive the same or lower doses of 
the investigational compound.
At the time of dose escalation, dose levels of new cohorts may be adjusted to lower doses if the accumulated safety 
data so dictates.
Adaptive dose selection may be performed to adjust some pre-selected doses, e.g., the third or/and fourth cohort 
doses, using accumulated efficacy and dose or exposure data. Models based on response rate, such as but not limited 
to (Bayesian) logistic regression, (Bayesian) EMax model, may be utilized to predict a dose satisfying certain

efficacy criteria, which might be different from the standard. If there are enough responding subjects with multiple 
platelet measurements, changes of platelet count may be directly modeled by dose and study day to facilitate dose 
prediction. The selected dose for a cohort should not exceed the originally planned dose for that cohort, i.e., selected 
dose for cohort C should not be larger than 675mg and it should be at most 1500mg for cohort D.

Early Decision of Dose escalation for dose panel
When a cohort is filled and a new subject is available to be treated, an early decision can be made on whether to 
open the next higher cohort if not all the subjects have completed the evaluation period. The early decision rule is 
based on controlling the probability of making a wrong early decision, called decision risk, to be at most 15%. 
Detailed information on deriving the decision risk is included in Appendix 1. 
The early decision rule is based on the largest number of subjects who developed AE of interest which is drug-
related SAE within the same organ system at grade 3 or higher. The early decision does not directly take into 
consideration other criteria as covered by the stopping rule. As such, its decision can be modified upon agreement 
from both investigators and sponsor. In case subjects are allocated to the higher cohort and at least one stopping rule 
as stated above is triggered toward the lower dose cohort when more events are observed at the lower cohort, 
decision will be made upon agreement from both investigators and sponsor after considering all safety data.
Three count numbers are used by the decision rule and are defined as follows.

Titration-Dose Evaluable Subjects (nH): the number of subjects who are titrated and complete the evaluation 
period (2 weeks) starting from the first titration dose (on day 43).

Start-Dose Evaluable Subjects (nL): the number of subjects who develop drug related SAE at grade 3 or higher 
or complete the evaluation period (2 weeks) from the first dose (on day 1) but haven’t completed the 2 weeks 
evaluation period following the first titration dose (on day 43) if being titrated to a higher dose.


Subjects with AE of Interest (k): the largest number of subjects who developed drug related SAE within the 
same organ system at grade 3 or higher, which could happen any time after the first dose of BMS-986004 till 
the decision making day. The value of k is allowed to be either 0 or 1. Note that it doesn’t distinguish at which 
stage of treatment, prior to or post titration, that such AE happened.
Minimum Requirement for Cohort Escalation
A set of minimum safety requirement, as listed below, must be met in order to make an early decision.

There must be at least 5 (nL+nH>=5) safety evaluable subjects (with safety data through study Day 15)

A higher dose than the new cohort’s start dose must be shown tolerated in the IM140-002 study.
Early Decision Rule:
If there is not AE of interest observed, the early decision rule is the same as the minimum requirements.
If there is one AE of interest observed, the early decision rule is shown in Table 3.1.4-1, where W represent wait, 
i.e., not enough evidence to enable dose panel escalation, and E represents escalate.
If there are least two subjects with AE of interest, stopping rule is triggered, and subject cannot be treated at the next 
higher cohort.
Study Population:  
Male and Female subjects ≥18 years old with persistent or chronic ITP according to American Society of 
Hematology (ASH), with or without prior splenectomy guidelines will be eligible to participate in 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

platelet antibody titers will be measured to explore possible effects on the primary pathogenic disease 
mechanism in ITP. Whole genome RNA profiling in the peripheral blood will be undertaken to explore CD40 
pathway activation and to enumerate plasmablasts by gene expression. Peripheral blood mononuclear cells 
(PBMCs) will be purified from whole blood and analyzed by flow cytometry to determine if baseline leukocyte 
phenotypes inform on patient response to therapy and/or if leukocyte phenotypes are affected by drug therapy. 
Plasma molecules that may be associated with the disease or drug target pathway, including cytokines and 
chemokines, will be measured. The primary safety biomarkers, d-Dimer and Thrombin anti-Thrombin (TAT), 
will be monitored to evaluate risk of thromboembolism. Exploratory safety biomarkers to monitor possible 
effects on protective immunity will include immune cell enumeration by T, B, NK TruCount and phenotyping 
by flow cytometry. 
Statistical Considerations:
Sample Size:
The number of subjects is not based on statistical power considerations. If 4 responders are observed out of 10 
subjects at a dose level, a 90% confidence interval for the response rate is (0.15, 0.70).
Endpoints:
Primary endpoints of safety will be measured by AE, SAE, ECG, and laboratory abnormalities including safety 
biomarkers of d-Dimer and TAT. 
Secondary endpoint of efficacy is measured by response rate. Secondary endpoints of PK include Cmax, CLT, 
AUC(TAU), Ctrough, AI_AUC, and AI_Cmax.
Exploratory endpoints include time to response, duration of response, and time to peak response.
Endpoints for the Long Term Extension Period
Primary endpoints of safety for the long-term extension period will be measured by AE, SAE, ECG, and laboratory 
abnormalities including safety biomarkers of d-Dimer and TAT.
The endpoint of efficacy is measured by response rate.
Analyses:
Demographics and Baseline Characteristics
Frequency distributions of gender and race will be tabulated. Summary statistics for age, body weight, height, and 
Body Mass Index (BMI) will be tabulated. Prior therapies will be listed and summarized for each dose.
Safety Analyses
All recorded adverse events will be listed and tabulated by system organ class, preferred term and treatment. Vital 
signs and clinical laboratory test results will be listed and summarized by treatment. Any significant physical 
examination findings, and clinical laboratory results will be listed. ECG readings will be evaluated by the 
investigator and abnormalities, if present, will be listed.
Efficacy Analyses
Platelet count and change from baseline will be listed for all treated subjects. Response status will be reported 
together with time to respond, time to peak response, and duration of response. Response rate will be provided by 
cohort and treatment phase (response phase or remission phase).
Bleeding score will be listed for each subject. Bleeding events and the number of subjects experiencing any bleeding 
episode will be summarized by panel.

Research Hypothesis 
Because current study is an open label trial without placebo control, there is no formal research 
hypothesis to be statistically validated. The purpose of this study is to test if BMS-986004 will
be effective in normalizing platelet counts in subjects with ITP, as well as to assess the safety, 
PK and immunogenicity of multiple doses of BMS-986004 in ITP subjects.

1.5
Overall Risk/Benefit Assessment
BMS-986004 is currently being evaluated in humans in a FIH SAD study which is being 
performed in healthy subjects to investigate the safety, tolerability, PK and PD of BMS-986004. 
To-date, BMS-986004 has not been studied in the ITP patient population and hence no efficacy 
or benefit data is established for this population. However, no clinically significant risks have 
been identified in the FIH study to-date and the safety margins in non-clinical studies are 
favorable which justifies careful evaluation of BMS-986004 in the ITP patient population.
BMS-986004 could potentially provide clinical benefit by normalizing platelet counts in patients 
with ITP.   This study will be initiating at a dose that has demonstrated relatively low 
immunosuppressive effect and has demonstrated no clinically significant risks in the FIH study.
Dose panels will be enrolled sequentially in an ascending manner upon careful review of all 
cumulative safety information. Cumulative safety data will include all additional data that is 
available in the FIH study as well as data collected during the ITP study. To manage the safety 
risks, careful clinical and laboratory monitoring and criteria relative to dose escalation and 
stopping rules have been established for this protocol and include thresholds for serious 
infections, liver function tests, platelet counts above established thresholds, and other adverse 
events. 
It is expected that ITP subjects will derive clinical benefit from BMS-986004 and help guide 
dose selection and design of future studies in the clinical development of BMS-986004. Primary 
efficacy assessments will include the proportion of patients achieving platelet count at least 
≥30,000/mm3 and at least 2-fold increase from the baseline count and absence of bleeding.
The subjects planned to be enrolled in this study have limited therapeutic options since they have 
failed conventional therapies including immunosuppresive therapies, splenectomy and TPO 
mimetics. It is anticipated that efficacious doses of BMS-986004 will provide long lasting

therapeutic benefit for ITP patients. Ultimately, targeting CD40L may provide opportunity to 
inhibit autoimmune processes leading to thrombocytopenia and induce durable disease 
remission. It may thus offer novel therapeutic modality, currently not available to patients.
Given the lack of therapeutic options for ITP subjects who have failed all conventional therapies, 
BMS-986004 with its distinct mechanism of action and known safety profile appears to have a 
favorable Risk/Benefit profile.
Detailed information regarding the preclinical toxicology findings based on nonclinical studies 
in monkeys with BMS-986004 can be found in Section 1.5.2 and the Investigator Brochure.
1.5.1
Potential risks associated with BMS-986004
BMS-986004 is a dimeric anti-human CD40L VH dAb formatted with the Fc-tail from abatacept 
(modified IgG1) that is entirely inert in Fc effector function, especially in context of FcγRIIa. All 
data from nonclinical and NHP studies demonstrate that BMS-986004 exhibited no activity in 
various platelet activation assays, as well as in direct biacore binding analysis with FcγRIIa. 
Based on previous clinical experience with antibodies targeting costimulatory molecules and in 
particular with anti-CD40L antibodies, potential risks include: (1) increased probability of TE; 
(2) an increase in susceptibility to infection and (3) immunogenic potential including infusion 
reactions and formation of ADA. In addition to conventional safety assessments, general risk 
mitigation plan includes the following:

To initiate dosing at 75 mg dose that has demonstrated favorable safety profile in healthy 
subjects in clinical evaluation. This dose is expected to elicit a sub-optimal response while 
ensuring very good safety profile.

To utilize safety criteria for intra-subject dose escalation and safety criteria for dose-panel 
escalation and stopping rules.
1.5.2
Potential Thromboembolic Effect
To continue to mitigate the potential risk of thromboembolism, the following safety measures are 
included in ITP study:

Close monitoring of any potential TE activities after BMS-986004 administration. In addition 
to observing clinical manifestations of both venous and arterial TE, the primary safety 
biomarkers, d-Dimer and Thrombin anti-Thrombin (TAT), will be monitored to evaluate risk 
of thromboembolism. 

TE related exclusion criteria have been added to the protocol; patients with history 
thromboembolic disease (including TIA, stroke, pulmonary embolism, deep vein thrombosis 
and thrombotic complications) or significant cardiovascular disease (including congestive 
heart failure, arrhythmias and other conditions known to increase risk of TE) are excluded.
1.5.3
Potential Immunosuppressive effect
As with any novel immunomodulating agent, there is a possibility of reducing normal immune 
function as a consequence of targeted CD40L blockade and therefore the following safety 
measures are included in the ITP study:


Exclusion criteria relative to positive tests for hepatitis B and C, TB and HIV have been 
included in the protocol.

Concurrent or recent use of systemic immune-modulating agents is prohibited or restricted to 
reduce potential risks associated with combinations of immune suppressors.

Patients will be very closely followed and evaluated for any signs or symptoms of infection 
and complete blood count (CBC) differential counts, lymphocyte immunophenotyping, and
measurement of serum Ig-levels (IgG, IgA and IgM) and CRP will be monitored frequently.
1.5.4
Risk of Infusion Reactions
As with any biological product, infusion reactions are a risk, even following a single dose. To 
reduce the risk of infusion reactions, patients will be closely monitored by trained personnel 
experienced with treatment of anaphylaxis and lesser infusion reactions. In addition, IV 
administration of study drug will not exceed infusion rate of 12.5 mg/min (Table 4-1). 
Furthermore, patients with history of any significant drug allergy or serious adverse reaction or 
hypersensitivity to any IV administered biologic will be excluded from the study.
1.5.5
Other
Risks from the PK, PD, and clinical safety phlebotomy procedures are standard and include 
discomfort at the injection site, bleeding, bruising, and rarely blood clot formation, infection, and 
fainting. Furthermore, rescue medications are permitted in the study for severe bleeding or wet 
purpura or if the investigator thinks the patients is at immediate risk. These medications are to 
be given with the intended purpose of raising platelet counts.

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.

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. 
The rights, safety, and well-being of the study subjects are the most important considerations and 
should prevail over interests of science and society.
Subjects in this trial will be invited to participate in a voluntary collection for future Medical 
Research. This collection is encouraged but not mandatory, and subjects who decline to 
participate will still be allowed to proceed with the rest of the study providing all other 
conditions are met.
This collection for future Medical Research is intended to expand the translational R&D 
capability at Bristol-Myers Squibb, and will support as yet undefined research aims that will 
advance our understanding of disease and options for treatment. It may also be used to support 
health authority requests for analysis, and advancement of pharmacodiagnostic development to 
better target drugs to the right patients.

INVESTIGATIONAL PLAN
3.1
Study Design and Duration
This is a Phase 1b/2, multicenter, open-label study to evaluate the safety, efficacy, dose response, 
and pharmacology (PK, target engagement and PD) of BMS-986004 in subjects with ITP. 
The study will comprise a short-term period and a long term extension (LTE) period. 
The short-term period, is divided into three phases: Response Phase (6 weeks), Remission Phase 
(6 weeks) and Follow Up phase (8 weeks).
Screening evaluations to determine subject eligibility will be performed 21 days prior to study 
drug administration. The screening period may exceed 21 days but not more than 42 days total, 
and only after a discussion with and approval by the Study Director. If an extension in screening 
time is granted, the patient must still follow the platelet count rules for enrollment. The baseline 
platelet count determining enrollment eligibility will be based on the mean of two determinations 
taken within a week of the first dose. To be eligible for enrollment, platelet count needs to be less 
than 30,000/ mm3 and show stable or declining trend. If the mean platelet count is between 
30,000 - 35,000/ mm3 the subject may be considered for enrollment on a case by case basis after 
discussion with and approval by the Study Director.
Following screening, a total of 40 evaluable subjects are planned for the study. Subjects are 
considered evaluable if they receive the first 4 doses of study drug and complete the required

safety and efficacy evaluations at Day 50. Non-evaluable subjects will be replaced to maintain a 
count of 10 subjects in each dose panels, except subjects will not be replaced if they are 
discontinued from the study secondary to an adverse event unless the adverse event can be 
determined to be unrelated to treatment.
Subjects are treated in dose panels of 10 subjects each. Four (4) dose panels are planned to be 
enrolled sequentially in an ascending manner, with dose intensity selected to provide increased 
levels of immunosuppression at steady state. Dose levels (range from 75 mg to 1500 mg 
administered every two weeks) that are planned to be evaluated in this trial are expected to elicit 
a range of clinical response. 
BMS-986004 will be administered once every 2 weeks as an IV infusion for a total of 7 doses.
Four (4) doses will be administered during the Response Phase over a 6 week treatment period. 
The remaining 3 doses will be administered during the Remission Phase of the study over a
6 week treatment period. Subjects will receive investigational product on Day 1/Week 0, Week 
2, Week 4, Week 6, Week 8, Week 10 and Week 12, for a total of 7 doses. 
Each dose cohort will enroll 10 new subjects, starting with the respective dose level at 
Day1/Week 0, regardless of the number of subjects joining a dose cohort because of intra-subject 
dose escalation. 
A new cohort may be opened to treat subjects at a dose lower than 75 mg if at least 6 subjects 
treated at the 75 mg cohort achieve platelet Response (R) (platelet count ≥ 30,000/mm3 and at 
least 2-fold increase from the baseline count and absence of bleeding), at the end of response 
phase (Week 6). The new cohort would follow the same schedule as the other cohorts including 
intra-subject dose escalation.
The long term extension (LTE) period is optional and will include eligible subjects from either 
cohort 3 or cohort 4 who complete 12 weeks (85-days) of treatment and who achieve a response
as defined by at least a doubling of platelets from Short Term Day 1 baseline and a platelet count 
of ≥ 35,000/mm3, and absence of bleeding and any significant AEs as assessed on D71 or if more 
recent platelet count is available, based on the most recent platelet count or on the average of the 
two consecutive most recent platelet counts, whichever is higher. If a subject has platelet counts 
close to a doubling of platelets and/or between 30,000-35,000 platelets/mm3 and absence of 
bleeding and any significant AEs as assessed on D71, the subject may be considered for the long 
term extension on a case by case basis, which will involve a review of data from the short term 
period and which will require approval by the Study Director.
3.1.1
Intra-subject dose escalation
Intra-subject dose escalation could occur after the subject has completed the Response Phase of 
the study. The intra-subject dose escalation decision will be based on review of the safety 
information and platelet count after 4 weeks of treatment. The decision to escalate dose for the 
subject will be made after evaluating platelet count at Day 50, 7 days after the 4th dose of 
BMS-986004 has been administered. Subject will receive the next higher dose of BMS-986004 if 
clinically significant response has not been achieved based on measurement of platelet count on

the last two consecutive counts performed at Day 43 and Day 50, and a favorable safety profile is 
observed (see Table 3.1.1-1). Clinically significant response is defined as achieving platelet 
count ≥ 50,000/mm3 with an increase of at least 20,000/mm3 from baseline and absence of 
bleeding. Subject will then be dosed at the higher dose level for the remainder of the study 
(Remission Phase), receiving investigational product at that dose on Week 8, Week 10 and Week 
12. Active treatment period with BMS-986004, regardless of the dose, may not exceed 12 weeks 
for any individual subject.

subjects) platelet count
For both the Short Term Study and the Long Term Extension plan, in the event that platelet
count exceeds 450,000/mm3 for non-splenectomized subjects and 600,000/mm3 for subjects who 
underwent splenectomy, in the absence of recent (administered within two weeks) rescue 
medication, as indicated by the two consecutive platelet count measurements, dosing of the 
BMS-986004 should be stopped. Subject will remain in the study and platelet counts will be then 
assessed based on the normal study visit schedule. Dosing of BMS-986004 could be reinitiated 
only after discussion between Study Director and Investigator if clinically appropriate and 
dictated by the medical judgment and subject’s safety.
3.1.3
Dose escalation for dose panel and stopping rules
Decisions regarding dose escalation will be made based on the review of all cumulative safety 
information which includes, in general, the safety data through study Day 15 from the 
10 subjects in the preceding lower dose cohort. If neither of the below stopping rules is present in 
dose panel, then dose escalation may proceed within the next higher dose level. However, 
escalation to the next higher cohort may occur when none of the stopping rules have been met 
and no less than 5 subjects in a cohort have been followed for at least 2 weeks under certain
conditions as illustrated in section 3.1.4.
The stopping rules listed below will be used to determine whether it is safe to escalate to the next 
higher cohort. Dose escalation to the next planned dose will not proceed if any of the following 
criteria are met (Adverse event grading as defined by the Common Terminology Criteria for 
Adverse Events [CTCAE, Version 4.0]):

Five or more subjects in a cohort have platelet counts >450,000/mm3 for non-splenectomized 
subjects and >600,000/mm3 for subjects who underwent splenectomy, and platelet count 
raise is not attributable to a rescue or concomitant therapy.

Two or more subjects have serious adverse events in the same organ system (Grade 3 and 
above), that are determined to be related to study medication,

It is determined that the limit of safety and/or tolerability has been reached. This decision 
will be made following discussions between the Study Team and the Investigator,
If any of the above criteria are met within a dose level, the progression to a higher dose level will 
be put on hold and all safety data available across the study will be evaluated to estimate the risk 
of proceeding to the higher dose level. The review will include all of the subject(s) that 
experienced SAEs listed above. In addition, data set may include subjects from a dose panel, the 
entire dose panel, or if appropriate, all randomized subjects treated to date. 
In addition, decision may be made following discussions between the Study Team and the 
Investigator to halt dose escalation for reasons not defined above, including but not limited to, 
observing a single serious adverse event in individual subjects, observing trends in a given dose 
panel and across dose panels, and/or it is determined that the limit of safety and/or tolerability 
has been reached. 
If dose escalation is stopped due to any of these findings, additional cohorts may receive the 
same or lower doses of the investigational compound.
At the time of dose escalation, dose levels of new cohorts may be adjusted to lower doses if the 
accumulated safety data so dictates.
Adaptive dose selection may be performed to adjust some pre-selected doses, e.g., the third 
or/and fourth cohort doses, using accumulated efficacy and dose or exposure data. Models based 
on response rate, such as but not limited to (Bayesian) logistic regression, (Bayesian) EMax, may 
be utilized to predict a dose satisfying certain efficacy criteria, which might be different from the 
standard. If there are enough responding subjects with multiple platelet measurements, changes 
of platelet count may be directly modeled by dose and study day to facilitate dose prediction.
The selected dose for a cohort should not exceed the originally planned dose for that cohort, i.e., 
selected dose for cohort C should not be larger than 675mg and it should be at most 1500 mg for 
cohort D.

3.1.4
Early decision of dose escalation for dose panel
When a cohort is filled and a new subject is available to be treated, an early decision can be 
made on whether to open the next higher cohort if not all the subjects have completed the 
evaluation period. The early decision rule is based on controlling the probability of making a 
wrong early decision, called decision risk, to be at most 15%. Detailed information on deriving 
the decision risk is included in Appendix 1.
The early decision rule is based on the largest number of subjects who developed AE of interest 
which is drug-related SAE within the same organ system at grade 3 or higher. The early decision 
does not directly take into consideration other criteria as covered by the stopping rule. As such, 
its decision can be modified upon agreement from both investigators and sponsor. In case 
subjects are allocated to the higher cohort and at least one stopping rule as stated above is 
triggered toward the lower dose cohort when more events are observed at the lower cohort, 
decision will be made upon agreement from both investigators and sponsor after considering all 
safety data. 
Three count numbers are used by the decision rule and are defined as follows.

Titration-Dose Evaluable Subjects (nH): the number of subjects who are titrated and 
complete the evaluation period (2 weeks) starting from the first titration dose (on day 43).

Start-Dose Evaluable Subjects (nL): the number of subjects who develop drug related SAE at 
grade 3 or higher or complete the evaluation period (2 weeks) from the first dose (on day 1) 
but haven’t completed the 2 weeks evaluation period following the first titration dose (on day 
43) if being titrated to a higher dose.

Subjects with AE of Interest (k): the largest number of subjects who developed drug-related 
SAE within the same organ system at grade 3 or higher, which could happen any time after 
the first dose of BMS-986004 till the decision making day. The value of k is allowed to be 
either 0 or 1. Note that it doesn’t distinguish at which stage of treatment, prior to or post 
titration, that such AE happened.
Minimum Requirement for Cohort Escalation
A set of minimum safety requirement, as listed below, must be met in order to make an early 
decision.


There must be at least 5 (nL+nH>=5) safety evaluable subjects (with safety data through 
study Day 15)

A higher dose than the new cohort’s start dose must be shown tolerated in the IM140-002 
study.
Early Decision Rule:
If there is not AE of interest observed, the early decision rule is the same the minimum 
requirements.
If there is one AE of interest observed, the early decision rule is shown below in Table 3.1.4-1, 
where W represent wait, i.e., not enough evidence to enable dose panel escalation, and E 
represents escalate.
If there are least two subjects with AE of interest, stopping rule is triggered, and subject cannot 
be treated at the next higher cohort.

analysis. Approximately 910 mL of blood will be drawn from each subject during the short-term 
period (~162 days including Screening and follow up period). Less than 500mL of blood will be 
drawn during the LTE period.
The approximate duration of the short-term period is 23 weeks (approximately 162 Days).  This 
includes a 21 day screening period, a 12 week treatment period and a 2 month follow up period.
An extended screening period (up to 42 days) is possible but only with the approval of the Study 
Director, and all other eligibility rules and screening rules must still be met. If subject is eligible 
and opts to continue into LTE, the 2 month follow-up period will not be performed after the 
short-term period is completed and the subject will enter the LTE directly. If the subject opts not 
to enter the LTE, then a 2 month follow-up visit will be completed. 
The approximate duration of the long term extension is approximately 55 weeks. This includes 
24 weeks of every other week dosing of 1500 mg, two-taper visits (7 weeks total), and a 24 week 
follow-up period (no treatment).
3.1.5
Long Term Extension
The long term extension (LTE) period is optional and will include eligible subjects who have 
completed Day 85 (12-weeks of treatment) and who have consented to participate. Eligible 
subjects [platelet count ≥ 35,000/mm3 with at least a doubling of platelets from short-term 
baseline, or patients approved by the Study Director on a case by case basis who are close to a 
two-fold increase from short term baseline and/or have 30,000-35,000 /mm3 platelets and 
absence of bleeding and any significant AEs as assessed on D71 or if more recent platelet count 
is available, based on the most recent platelet count or on the average of the two consecutive 
most recent platelet counts, whichever is higher], will receive a 1500 mg dose every other week 
for 24 weeks. Subjects who complete 24 weeks LTE will receive a taper regimen consisting of 
1500mg dose on Day 190 and a final dose on Day 218 before entering the 24 week follow-up 
period (no treatment). 
A separate informed consent must be signed by the patients to enter the LTE period.
3.2
Post Study Access to Therapy
At the end of the 12 week treatment study period, all eligible subjects in Cohort 3 and 4 will have 
the option to continue into the LTE period. The investigator should ensure that the subject 
receives appropriate standard of care to treat the condition under study.
3.3
Study Population
For entry into the short-term period of the study, the following criteria MUST be met prior to 
dosing on Day 1 of the Short Term Period. No exceptions will be granted. 
For entry into the long term extension, subjects must remain on study medication, complete the 
short-term period (up to 12 weeks of treatment), qualify per guidance for an increase in platelet 
count and safety, and sign a new informed consent.

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, 
Females 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 
judgement in checking serum FSH levels. If the serum FSH level is >40 mlU/ml at any time 
during the washout period, the woman can considered postmenopausal

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)

An opportunistic or systemic fungal, viral or bacterial infection of a serious nature, that in the 
opinion of the investigator or medical monitor, contraindicates further dosing of 
investigational product after resolution.

Malignancy, except basal cell carcinoma.

Severe hypersensitivity reaction (anaphylaxis) to the study drug, Grade 3 or higher
In the case of pregnancy, the investigator must immediately notify the BMS Medical 
Monitor/designee of this event. In most cases, the study drug will be permanently discontinued in 
an appropriate manner. If the investigator determines a possible favorable benefit/risk ratio that

warrants continuation of study drug, a discussion between the investigator and the BMS Medical 
Monitor/designee must occur.
All subjects who discontinue 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).
Subjects refusing to return to the site or to continue participation in the study should be 
documented as “withdrawal of consent” rather than “lost to follow-up.” Investigators should 
document attempts to re-establish contact with missing subjects throughout the study period. If 
contact with a missing subject is re-established, the subject should not be considered 
lost-to-follow-up and any evaluations should resume according to the protocol.
If study drug is discontinued prior to the subject’s completion of the study, the reason for the 
discontinuation must be documented in the subject’s medical records and entered on the 
appropriate case report form (CRF) page.
3.6
Post Study Drug Follow up
In this study, increase in platelet count is a key endpoint of the study. Post treatment study 
follow-up is of critical importance and is essential to preserving subject safety and the integrity 
of the study. Subjects who discontinue study treatment 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.

The study drug should be dispensed by the pharmacist or qualified designee and administered as 
an infusion using an infusion pump. Do not ever administer study drug by intravenous push 
(IVP) or bolus injection. A physician must be present at the infusion site during all 
administrations of study drug.
Vital signs (blood pressure, heart rate, respiratory rate, and temperature) will be monitored 
before infusion (at anytime the day of dosing, prior to infusion), approximately every 15 minutes 
during infusion, at the end of the infusion (within 10 minutes after the infusion has stopped), and 
approximately every 30 minutes after completion of the infusion until stable, as judged by the 
investigator. If an anaphylactoid-like infusion reaction or anaphylactic reaction occurs, vital 
signs will be taken more frequently, as warranted by the severity of the reaction. Blood pressure 
and heart rate will also be taken prior to discharge from the site on visits in which study drug is 
administered.
Subjects should not be premedicated unless they have had a prior infusion reaction, since the 
primary objective of this study is to evaluate the expected frequency of safety events and 
tolerability of the study drug. However, after a reaction determined to be an infusion reaction has 
been documented, the investigator may elect to administer prophylactically an anti-histamine or 
Tylenol for the comfort and safety of the subject prior to subsequent infusions.
Product description and storage information is described in Table 4-3.

Investigational Product
An investigational product, also known as investigational medicinal product in some regions, is 
defined a pharmaceutical form of an active substance or placebo being tested or used as a 
reference in a clinical study, including products already with a marketing authorization but used 
or assembled (formulated or packaged) differently than the authorized form, or used for an 
unauthorized indication, or when used to gain further information about the authorized form.
The investigational product should be stored in a secure area according to local regulations. It is 
the responsibility of the investigator to ensure that investigational product is only dispensed to 
study subjects. The investigational product must be dispensed only from official study sites by 
authorized personnel according to local regulations. 
In this protocol, investigational product is: BMS-986004 Injection. BMS-986004 is a clear to 
slightly opalescent, colorless to pale yellow solution; may contain particulate matter upon visual 
inspection. The drug product is a preservative free, ready to use solution contained in a 10 cc vial 
with 20 mm opening, Type I flint glass, 1-panel, open label. 
Each vial of drug product contains the labeled amount of BMS-986004, 190 mg/vial (50 mg/mL) 
in 10 mM Sodium Phosphate, pH 6.5, 25 mM Arginine HCl, 250 mM Sucrose. A 13% overfill is 
included in each vial to account for vial, needle syringe (VNS) holdup. This drug product can be 
used for intravenous administration only
4.2
Non-investigational Product
Not Applicable. 
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.
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 Intravenous Use
Dilution of BMS-986004 Injection for IV use must be performed using sterile disposable 
syringes. Prior to IV administration, BMS-986004 Injection is diluted with 0.9% Sodium 
Chloride Injection (NS) to prepare dosing solutions with BMS-986004 concentrations ranging 
from 1.5 to 15 mg/mL. The product is to be infused over 2 hours for each panel, using a 
volumetric pump at the protocol specific dose(s) and rate(s) through the IV infusion set as 
indicated in Table 4-1. Care must be taken to ensure the sterility of the prepared solution, as the 
drug product does not contain anti-microbial preservatives or bacteriostatic agents.

BMS-986004 Injection should be stored refrigerated at 2° - 8°C (36° - 46°) with protection from 
light. After withdrawal into an appropriate sized syringe and dilution with NS (in the 
concentration range of 1.5 to 15 mg/mL), the product must be administered intravenously within 
two hours. The diluted BMS-986004 solutions  may be stored in PVC, IV bags for up to 24 hours 
at refrigerated and protected from light, (2° - 8°C) or up to 4 hours (which includes the infusion 
time of two hours) at room temperature (15° - 25°C) and ambient lighting conditions. Regardless 
of the storage condition, the BMS-986004 infusion must be completed within 24 hours after 
transfer of the reconstituted BMS-986004 solution to an infusion container and dilution in 
normal saline. 
Recommended safety measures for preparation and handling include protective clothing, gloves, 
and safety cabinets. Partially used or empty vials of BMS-986004 Injection should be discarded 
as per the site procedures
4.4
Method of Assigning Subject Identification
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. 
Enrolled subjects meeting all eligibility criteria will be assigned to a dose cohort. Specific
instructions regarding enrollment and dose cohort assignment will be provided to the
investigational sites in their training materials.
Specific instructions for using IVRS will be provided to the investigational sites in a separate
document.
Subjects will not be replaced if they are discontinued from the study secondary to an adverse 
event unless the adverse event can be determined to be unrelated to treatment. The replacement 
subject will receive the same treatment as the subject being replaced.
4.5
Selection and Timing of Dose for Each Subject
Dose escalation and modifications will be guided by the approach described in Section 3.1.
4.6
Blinding/Unblinding
Not applicable.
4.7
Treatment Compliance
Investigational product is administered by study site personnel, who will monitor compliance.
After administration of BMS-986004, an examination of the injection site is required.

In the event of multiple procedures are required at a single timepoint, the following is a list of 
procedures from highest priority to low:
1) Pharmacokinetic Sampling
2) Safety (ECG)
3) Safety (clinical labs)
5.1.1
Retesting During Screening or Lead-in Period
Retesting of laboratory parameters and/or other assessments within any single Screening or 
Lead-in period will be permitted (in addition to any parameters that require a confirmatory 
value).
Any new result will override the previous result (i.e., 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.
5.2
Study Materials
The site will provide all required materials for the tests performed locally (ie, relevant clinical 
laboratory tests and urine drug screens). 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. A current and fully stocked advanced cardiac life 
support (ACLS) cart will be immediately available on the premises. The site will have a 
refrigerated centrifuge, a monitored and alarmed refrigerator, and freezer (-20°C or below), as 
well as containers and dry ice for shipment and storage of blood samples. The site will provide 
all materials required for accurate source documentation of study activities and for housing the 
subjects during the study. BMS will provide a BMS approved protocol and any amendments or 
administrative letters (if required), The Bleeding Assessment Tool (ITP-BAT), BMS-986004
Investigator Brochure, Pregnancy surveillance forms, NCI CTCAE version 4.0 and a Pharmacy 
Manual. Case report forms (electronic or hard copy) will be provided by BMS. The Central 
Laboratory will provide a lab manual, labels and tubes for the collection and handling of blood 
(including PKs, biomarker and immunogenicity) specimens.
5.3
Safety Assessments
Safety assessments will be based on medical review of adverse event reports and the results of 
vital sign measurements, ECGs, physical examinations, clinical laboratory tests and clinical 
tolerability of the drug. 
The safety of BMS-986004 will be assessed primarily by summarizing treatment emergent 
AEs/SAEs and by evaluating laboratory and biomarker safety assessment, including hematology, 
clinical chemistry and coagulation.

5.5.2
Pharmacokinetic Sample Analyses
The serum samples will be analyzed for BMS-986004 by a validated ligand binding assay. In 
addition, serum samples will be archived for potential exposure-biomarker or other exploratory 
analysis, if the need arises and to the extent possible. Exploratory biomarker analysis may 
include assessment of markers associated with inflammatory or autoimmune disease, molecules 
associated with ITP or disease mechanism of action and signaling pathways, with the drug target, 
CD40L, or drug target mechanism of action and signaling pathways, and/or with patient response

5.6.1
Primary Safety (TE) Biomarker Assessments
Previous molecules in clinical development targeting CD40L have demonstrated the potential to 
induce thromboembolism (TE). All data from nonclinical, NHP and single ascending dose 
clinical study of BMS-986004 are consistent with the conclusion that BMS-986004 does not
possess platelet activating or other activity associated with the induction of TE. To further 
mitigate the risk of TE in subjects dosed with BMS-986004, a set of primary, accepted markers 
of platelet activation and TE potential will be monitored at frequent intervals and analyzed in 
real-time. Plasma and serum will be collected to monitor the risk and minimize impact of a 
potential TE event. Prothrombin time (PT) and activated Partial thromboplastin time (aPTT) will 
be assessed at screening as measures of a hypercoagulable state. D-dimer and thrombin anti-
thrombin (TAT) in plasma will be quantified as measures of TE risk. Serum troponin I will be 
monitored as an indicator of potentially TE-related subclinical myocardial infarction. Data from 
these primary safety biomarker measurements will be collected and carefully evaluated in the 
context of a thorough review of all available clinical data and used to formulate go/no-go 
decisions prior to dose escalation.

Sampling for Medical Research
Where individual subjects have provided separate consent for Medical Research collection, 
residual samples of serum, plasma, RNA and PBMCs will be retained by the BMS Biobank for 
medical research purposes. No additional sampling is required for residual collections. Medical
research collections and retention should be presented to all subjects, except where prohibited by 
local laws or regulations. However, enrollment into the main study is not contingent upon 
consent to participate in future medical research sample banking. 
6
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.)
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

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).
NOTE: 
The following hospitalizations are not considered SAEs in BMS clinical studies: 

a visit to the emergency room or other hospital department < 24 hours, that does not 
result in admission (unless considered an important medical or life-threatening event)

elective surgery, planned prior to signing consent

admissions as per protocol for a planned medical/surgical procedure

routine health assessment requiring admission for baseline/trending of health status (eg, 
routine colonoscopy)

medical/surgical admission other than to remedy ill health and planned prior to entry into 
the study. Appropriate documentation is required in these cases

admission encountered for another life circumstance that carries no bearing on health 
status and requires no medical/surgical intervention (eg, lack of housing, economic 
inadequacy, caregiver respite, family circumstances, administrative reason).

Admission for administration of anticancer therapy in the absence of any other SAEs 
(applies to oncology protocols)
6.1.1
Serious Adverse Event Collection and Reporting
Sections 5.6.1 and 5.6.2 in the Investigator 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 3 months of discontinuation of dosing. If applicable, SAEs must be collected that 
relate to any later protocol-specified procedure (eg, a follow-up skin biopsy).

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 wherever possible, the clinical rather than laboratory term would be used by 
the reporting investigator (eg, anemia versus low hemoglobin value).
6.4
Pregnancy
If, following initiation of the 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.
In most cases, the study drug will be permanently discontinued in an appropriate manner (eg, 
dose tapering if necessary for subject safety).
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.

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)
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential DILI event. All occurrences of potential DILIs, 
meeting the defined criteria, must be reported as SAEs (see Section 6.1.1 for reporting details).
Potential drug induced liver injury is defined as: 
1. AT (ALT or AST) elevation > 3 times upper limit of normal (ULN)
AND 
2. Total bilirubin > 2 times ULN, without initial findings of cholestasis (elevated serum alkaline 
phosphatase),
AND 
3. No other immediately apparent possible causes of AT elevation and hyperbilirubinemia, 
including, but not limited to, viral hepatitis, pre-existing chronic or acute liver disease, or the 
administration of other drug(s) known to be hepatotoxic. 
The key responsibilities for investigators during p-DILI assessment include: (i) Early detection, 
medical evaluation (including the exclusion of other potential causes) and rapid laboratory 
confirmation of liver-related abnormalities, and (ii) Sponsor notification of p- DILI cases via 
SAE forms. Following the gathering and assessment of relevant clinical information the sponsor 
is responsible for: (iii) Timely evaluation and triaging of p-DILI cases, (iv) Expedited reporting 
of p-DILI cases and (v) Expanded review of p-DILI cases including a detailed assessment of all 
available clinical information, investigations and biochemical data.
Investigators are expected to monitor ongoing routine and ad hoc hepatic laboratory test results 
to rapidly determine whether a subject meets p-DILI criteria. They are expected to promptly 
notify BMS of all p-DILI cases. p-DILI cases may be identified by abnormal liver biochemistry 
values, whether or not they are accompanied by liver-related signs and/or symptoms. In both 
cases, expedited confirmation with repeat laboratory testing should occur within 3 business days 
using a Hepatic Laboratory Panel (ALT, AST, TB, AP). Any subject with an abnormal Hepatic 
Laboratory Panel that meets p-DILI criteria is a candidate for study drug discontinuation. Any 
confirmed p-DILI events must be reported (along with a description of the clinical findings) to 
BMS as an SAE within 24hrs of confirmation. 
An extensive clinical history, examination and appropriate investigations should be obtained to 
exclude cholestatic and other apparent causes that may explain the observed abnormalities in 
liver function and/or hepatic signs and symptoms. Other apparent causes include,

non-exhaustively and by way of example only: infectious diseases (such as active hepatitis -A, 
-B and -C), congenital diseases (such as Gilbert’s syndrome), neoplastic diseases (such as 
hepatocellular carcinoma), automimmune diseases (such as primary biliary cirrhosis) and the use 
of concomitant hepatotoxic medications (such as antibiotics, the oral contraceptive pill and 
herbal medicines). All investigations to exclude potential causes of liver function abnormalities 
or hepatic signs and/or symptoms should be guided by relevant factors such as the subject’s age, 
gender, clinical history, and signs and symptoms. If necessary, after discussion with Sponsor’s 
safety team, Investigator may perform additional diagnostic tests/procedures to further diagnose 
pDILI (e.g. ultrasound, MRI/MRS, liver biopsy).

worsening
noted 
during

DATA MONITORING COMMITTEE AND OTHER EXTERNAL 
COMMITTEES
A Data Monitoring Committee (DMC) will perform safety and efficacy assessments at regularly 
scheduled times as well as on an ad hoc basis if needed. The DMC will review relevant safety 
data from preceding Cohorts before the study progresses to the next Cohort. In addition, formal 
DMC monitoring meetings will occur when a maximum of 20 subjects have had at least 6 weeks 
of exposure during the Response Period or 6 months after the first subject is randomized to the 
study (whichever comes first).
Thereafter, DMC monitoring will be performed at approximately 4 month intervals or after each 
additional 10 subjects have had at least 11 weeks of exposure (whichever comes first) until all 
subjects are enrolled into the study. At that time, the DMC will meet every 6 months. With the 
agreement of DMC and BMS this schedule may be modified depending on the rate of subject 
accrual.
The DMC will review safety data including serious adverse events and events of special interest, 
focusing on early signal detection. The DMC will also evaluate the rates of clinical response 
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. These reviews will be conducted by an internal data monitoring committee made up 
of representatives of the sponsor who are not involved in the day-to-day conduct of the study.

measurements, physical examinations, clinical laboratory tests, and ECG parameters including 
heart rate, PR interval, QRS interval, and QTcF interval (QT interval corrected for heart rate).
8.3.2
Secondary Endpoint(s)
The first secondary objective of efficacy will be measured by the following secondary endpoints:

Response Rate (RR): Response rate is defined as the proportion of subjects who are 
responders.
The second secondary objective of assessing pharmacokinetics of BMS-986004 after one and 
multiple doses will be measured by the following secondary endpoints:

Cmax: Maximum observed serum concentration

AUC(TAU): Area under the concentration-time curve in one dosing interval

Ctrough: Trough observed serum concentration

CLT: Total body clearance


Interim Analyses
Data emerging from each panel of this exploratory study may be used for timely decisions about 
adjustments to procedures in subsequent panels, including but not limited to, dose of next higher 
panel, an intermediate dose, and early termination of the study. No formal inferences requiring 
any adjustment to statistical significance level will be performed. 
Models, including but not limited to Bayesian logistic regression, Bayesian EMax, and linear or 
nonlinear regression models, will be examined and built to predict a dose to achieve certain 
efficacy outcomes such as desired response rate or platelet count. Exposure data or PK 
parameters may be included in the model. Efficacy data obtained during the remission phase 
after a subject has been intra-subject dose escalated to a titration dose may be used to provide 
robust and reliable prediction. Timing of dose prediction could be as early as efficacy results 
becoming available for an enough number of subjects treated in the second cohort. Refer to

must be discussed with, and be prepared by, BMS. The investigator should not implement any 
deviation or change to the protocol without prior review and documented approval/favorable 
opinion from the IRB/IEC of an amendment, except where necessary to eliminate an immediate 
hazard(s) to study subjects. 
If a deviation or change to a protocol is implemented to eliminate an immediate hazard(s) prior 
to obtaining 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

If the revision is done via an administrative letter, investigators must inform their IRB(s)/IEC(s).
9.1.2
Monitoring
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.

9.2.3
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. 
The confidentiality of records that could identify subjects must be protected, respecting the

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 (e.g., 
calendar, ovulation, symptothermal, profession of abstinence 
for entry into a clinical trial, post-ovulation methods) and 
withdrawal, which are not acceptable methods of 
contraception. Subjects who choose complete abstinence are 
not required to use a second method of contraception, but 
female subjects must continue to have pregnancy tests. 
Acceptable alternate methods of highly effective 
contraception must be discussed in the event that the subject 
chooses to forego complete abstinence.

APPENDIX 1
ADAPTIVE EARLY DECISON FOR DOSE PANEL ESCALATION
Introduction
A model-based cohort escalation rule is established to help decide on opening the next cohort for 
newly enrolled subjects when current cohort is filled but not all of its subjects are monitored for 
2 whole weeks regarding drug toxicity and tolerability. The decision rule would allow treating 
subject, once available, at the next cohort without waiting for the completion of every subject’s 
AE evaluation period at the current cohort and at the same time keeping decision risk acceptably 
low.
Please note that AE would be closely monitored throughout the trial for each subject, and the 2 
weeks’ AE evaluation period mentioned here is for the purpose of cohort escalation only. During 
the evaluation period, the numbers of subjects who developed drug-related SAE within the same 
organ system at grade 3 or higher, called AE of interest are counted and the largest number will 
be used.
Decision Risk
The decision risk is mathematically defined as the probability of observing enough number of 
event(s) in the still non-evaluable subjects given data collected from evaluable subjects such that 
cohort escalation is not allowed. Evaluable subjects are those who are observed an AE of interest 
or complete the AE evaluation period. To enroll subject into the next cohort, the non-adaptive 
cohort escalation rule requires, among others, no more than one subject being reported drug-
related serious adverse event or serious infection and infestation within the evaluation period. 
Therefore, if one subject is observed with an AE of interest, the decision risk would be the 
probability of observing at least one more AE of interest in the non-evaluable subjects; if no AE 
of interest is reported, the decision risk is thus the probability of observing at least two AEs of 
interest from the non-evaluable subjects.
Decision Data
To take advantage of the titration design, in which subjects could possibly take a higher dose that 
is to be used initially in the next cohort, the adaptive decision rule makes use of the following 
three statistics: 

Titration-Dose Evaluable Subjects (nH): the number of subjects who are titrated and 
complete the evaluation period (2 weeks) starting from the titration’s first dose (on day 43).

Start-Dose Evaluable Subjects (nL): the number of subjects who develop drug related SAE at 
grade 3 or higher or complete the evaluation period (2 weeks) from the first dose (on day 1) 
but haven’t completed the 2 weeks evaluation period following the first titration dose (on day 
43) if being titrated to a higher dose.

Count of AE of Interest (k): number of subjects with AE of interests, which could happen 
any time after the first dose of BMS-986004 till the decision making day. Apparently, k=0 or 
1. Please note that it doesn’t distinguish at which stage, prior to or post titration, that such AE 
happened.
With sample size of 10 for each cohort, the number if non-evaluable subjects is 10-nH-nL.

Decision Risk Estimation
Calculation of decision risk is based on the method of Bayesian constrained rate estimate with 
ascending beta prior. It assumes that the rate of AE of interest increases with doses, however, no 
specific mathematical form is given governing the relationship between dose and rate. In this 
way, robustness is achieved by avoiding possible model misspecification. It also assumes that 
rate depends on the maximum dose subject takes, i.e., titrated subjects are equally likely in 
developing AE of interest as subjects who take the titrated dose right in the beginning. The prior 
information is solicited from a phase III study of Abatacept IM101174, in which 12 out 721 
subjects (1.7%) were reported to experience drug related SAEs within short term period (half 
year treatment). The prior used is Beta(0.01, 0.49), which indicates 2% rate and is equivalent of 
contributing 0.5 subject at each dose.
Decision risk for k=1 is listed below (values are provided only for when the number evaluable 
subjects, nH+nL, is at least 5, and at most 9). Bayesian MCMC simulation is performed to 
compute the posterior predictive probability under R version 3.1.0 with a random seed of 
20140625.

Decision Rule
Decision rule is derived by comparing decision risk to a pre-selected threshold value when the 
current cohort is filled and a newly enrolled subject is available to be allocated to the next cohort. 
If decision risk is less than the threshold value, the subject will be treated at the next cohort 
(denoted as E in the following table), otherwise, the subject need to wait for more evidence 
coming up (denoted as W). 
An example of decision rule for k=1 is shown below with decision risk being 15%.

APPENDIX 2
ADAPTIVE DOSE SELECTION
Introduction
Bayesian logistic regression model is used to predict an adaptive dose for a given response rate. 
Simulations of both logistic regression and Bayesian logistic regression are provided to show 
their performance in predicting dose for pre-selected response rate. New method of analyzing 
data obtained from the study with titration design is also included. More detailed discussion will 
be available in the study’s statistical analysis plan (SAP).  
Adaptive dose selection is not limited to the Bayesian logistic regression model described in this 
appendix. Alternative modeling includes, for example, nonlinear or linear mixed effect 
regression of longitudinal platelet count. Specifically, when PK exposure data are available, 
model based on PK exposure may be a better choice than that on dose only since there are only a 
few distinct values of doses. 
Adaptive dose selection can be performed as early as when the third cohort is about to enroll 
subjects. However, it is advised that the predicted dose would be more reliable when more data 
are available, e.g., when the fourth cohort is about to enroll. For safety reasons, the selected dose 
to be administered at a higher cohort cannot be larger than what is planned for that cohort.
Bayesian Logistic Model Description
The model is described below:
where, at each dose level i, di is dose in mg, pi is the expected response rate, ni is the number of 
subjects treated at dose di, and yi is the number of responders. Model parameters β are assumed a 
normal distribution with mean μ and variance ψ. Explaining variable, dose, is in log scale, and is 
subtracted by an offset of log(75), where 75 is the minimum dose administered at cohort 1. By 
subtracting such an offset value, intercept parameter μ alone can be interpreted as the log odd 
value of the expected response rate for cohort 1, and as such it is easy to set prior distribution 
parameters (shown below).
Prior of the model parameters is set under the following guidelines:

Model-predicted response rate at each dose level matches the expected rate.

A 97.5% quantile of the response rate at the lowest dose is around 0.4.

A 2.5% quantile of the response rate at the highest dose is around 0.35.

Extremely small probability for β2 being negative

It is assumed that the response rate at dose of 75mg, 225mg, 675mg, and 1500mg to be 0.2, 0.4, 
0.55 and 0.7 respectively. A linear regression using the above data will give prior mean μ to be ( 
-1.33, 0.72) with rounding error. The second and third bullets of the guidelines would make the 
stand deviation of β1 to be 0.45, and β2 to be 0.2. Prior distributions of β1 and β2 are assumed to 
be independent. A 95% credible interval of response rates under prior and without observation 
data is shown in Figure 1, where the top curve is the upper 97.5% quantile, the center is the 
mean, and the bottom is the lower 2.5% quantile. The circles represent the expected response 
rates at the selected doses. It can be seen that the chosen prior would lead to a mean response rate 
estimate being very close to the expected or assumed, and at the same time the wide region of 
95% credible interval indicates that the prior’s weak impact on the posterior estimation of 
response rate when data are observed.
Figure 1:
95% Credible Interval of Response Rate under Prior Only
Special consideration for titration
Non-responders at each cohort other than the maximum 1500mg cohort would be administered 
higher dose with the hope of becoming responders. Therefore, two response status data may be 
observed for those non-responders. Due to relative small sample size of each cohort, making use 
of status data after the titration dose is believed to increase the accuracy of model-based 
prediction under some reasonable assumptions. Listed in the below are two assumptions used in 
the adaptive dose selection:

If a subject responses to a dose, the subject would respond to higher dose with probability 1.


If a subject does not respond to a dose after 3 administrations, additional dosing at the same 
dose would not make a subject change from non-responder to responder.
Based on the above assumptions, a new approach is proposed to combine the subjects at two 
adjacent cohorts to estimate the response rate at the higher dose which is shared by the two 
cohorts.
Simulation
Trial simulation is done to show the performance of logistic regression and Bayesian logistic 
regression with starting dose data only or with titration data included. The Settings of simulation 
parameters are listed below for convenience:

Doses: 75, 225, 675, 1500

Rate: 0.2, 0.4, 0.55, 0.7

Conditional response rate for non-responder after titration:0.25, 0.25, 0.33

Response rate used to predict dose: 0.7 (equivalently the fourth cohort)

Number of simulated trials: 1000
Prediction results from four different methods are compared with each other.

SLogit: Logistic regression with response status from starting dose only

SBayLogit: Bayesian logistic regression with response status from starting dose only

DLogit: Logistic regression with response status from both starting dose and titration dose

DBayLogit: Bayesian logistic regression with response status from both starting dose and 
titration dose
Simulation results are shown in Figure 2. It can be seen that Bayesian modeling provides less 
variant and seemingly closer-to-true-value predictions compared to the usual logistic regression. 
In addition, variation of the predicted dose is smaller by including titration data when same 
modeling is used.

APPENDIX 3
INTERPRETATION OF HEPATITIS B SEROLOGICAL TEST
RESULTS
As our study drug is expected to demonstrate immunosuppressive effects, we find it necessary to 
carefully evaluate and exclude subjects with potentially active Hepatitis B infection. For this 
reason, in order to fully evaluate subject’s eligibility for enrollment, Exclusion Criterion 3f  
requires interpretation of data from three standard tests for hepatitis B i.e. measurement of 
hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs) and Hepatitis B 
core antibody (anti-HBc).
Subject’s eligibility for enrollment should be assessed as described below: 

Subjects that are negative for all three markers are allowed into the study

Subjects that are HBsAg (neg), anti-HBc (neg) and anti-HBs (pos) are allowed into the 
study (immunized subjects)

Subjects that are HBsAg (neg), anti-HBc (pos) and anti-HBs (pos) are allowed into the 
study (Hep B immune most likely due to natural exposure) 

Subjects that are HBsAg (pos) are excluded from the study

Subjects that are HBsAg (neg), anti-HBc (pos) and anti-HBs (neg) may be included after 
additional discussion with Medical Monitor in order to evaluate subject’s full clinical 
status and medical history.

STUDY DESCRIPTION
2.1
Study Design
This is a Phase 1b/2, multicenter, open-label, MAD study to evaluate the safety, efficacy, dose 
response, and pharmacology (PK, target engagement and PD) of BMS-986004 administered 
every 2 weeks in subjects with ITP.
Figure 2.1-1:
Study Design Schematic
The study is divided into screening (3 weeks), response phase (6 weeks), remission phase (6 
weeks) and follow up period (4 weeks). Forty subjects are treated in 4 dose panels, 75mg, 
225mg, 675mg, and 1500mg, of 10 subjects each. BMS-986004 will be administered on day 1, 
15, 29, 43, 57, 71, 85, a total of 7 doses as IV infusion. Four (4) doses will be administered 
during the Response Phase over a 6 week treatment period. The remaining 3 doses will be 
administered during the Remission Phase of the study over a 6 week treatment period. The study 
design schematic is presented in Figure 2.1-1.

ENDPOINTS
4.1
Efficacy Endpoints
The first secondary objective of efficacy will be measured by the following efficacy endpoint:

Response Rate (RR): Response rate is defined as the proportion of subjects who are 
responders.

Time to Response: It is defined as the time, in weeks, from the first dosing day until the
criteria for PR or CR are first met, whichever occurs earlier. Non-responders will be censored
on the date of their last platelet measurement.

Duration of Response: Duration of response is defined as the time, in weeks, from the first
day when the criteria are met for PR or CR, whichever occurs first, until the date of disease
progression. Subjects who do not progress will be censored on the date of their last platelet
measurement. It is defined for responders only.

Time to Peak Response: It is defined as the time, in weeks, from the first dosing day until the
largest platelet count is met. It is defined for responders only.
4.2
Safety Endpoints
Safety endpoints include incidence of AE at the highest grade, death as well as marked 
abnormalities in clinical laboratory tests, vital sign measurements, ECGs, and physical 
examinations. Incidence of AEs is provided separately for overall AEs, serious AEs, and AEs 
leading to discontinuation.
4.3
Pharmacokinetic Endpoints
Pharmacokinetic parameters of BMS-986004 will be derived from serum concentration versus 
time data by analyte and collection interval.  Individual pharmacokinetic parameter values will 
be derived by non-compartmental methods by a validated pharmacokinetic analysis program 
using actual times.

details in Section 7.5.4)
7.5
Efficacy
Efficacy results are assessed by platelet counts and bleeding SMOG scores obtained 
longitudinally through the study. The collection date and time are available in Table 7.10-1 (Both 
are collected at the same day).
7.5.1
Derivation of Efficacy Endpoints
Primary efficacy criteria and response category:

Response (R) - platelet count ≥ 30,000/mm3 and at least 2-fold increase from the baseline
count and absence of bleeding.

Complete Response (CR) - platelet count ≥ 100,000/mm3 and absence of bleeding.

No Response (NR) - platelet count < 30,000/mm3 or less than 2-fold increase of baseline 
platelet count or bleeding.

Not Assessable (NA) - platelet count is missing or is excluded due to rescue medication.
Subject’s best response is decided in the order of CR, R, NR, and NA.
Secondary efficacy criteria and response category:

Clinically Significant Response - platelet count ≥ 50,000/mm3 with an increase of at least 
20,000/mm3 from baseline and absence of bleeding.

No Clinically Significant Response - platelet count < 50,000/mm3, or increase of ≤ 
20,000/mm3 from baseline, or bleeding.

Not Assessable (NA) - platelet count is missing or is excluded due to rescue medication.
Absence of bleeding:
Absence of bleeding is defined as SMOG scores being zero for all the three major domains 
(Skin, visible mucosae, and organs) with ITP-BAT on the same day when platelet count is 
assessed. 
Platelet data exclusion and rescue medication flag:
Platelet counts collected within 4 weeks after any rescue medication, though still shown in listing 
of figures of raw data, will be excluded from summarizing platelet and deriving subject response. 
To facilitate the exclusion, rescue medication flag may be derived and included in some analysis 
datasets and listings if at least one subject takes rescue medication after the first dosing during 
the trial. Rescue medication flag is set to Y (Yes) within 4 weeks after the day any rescue 
medication is administered, i.e., between rescue medication day and rescue medication day + 27, 
inclusively. It will be set to N (No) when otherwise.

Bleeding SMOG score, platelet count, platelet change from baseline, potentially rescue 
medication flag, and response category (each under primary and secondary efficacy criteria) at 
each study day will be listed for all treated subjects.
Platelet count and change from line will be summarized by treatment group for each study day. 
Percent of visits with platelet count ≥ 30,000/mm3, 50,000/mm3, and 100,000/mm3 will be listed 
for each subject and summarized for each treatment group.
Platelet count and its change from baseline may be explored by graphs and statistical models. 
Details are available in the section of exploratory biomarker analysis.
Exploratory analysis of platelet count is shown in section 0.
7.5.4
Response with primary efficacy criteria
The best response status over the entire study will be reported for all treated subjects with 
platelet at baseline, administered dose on day 1, and administered dose on day 57. For 
responders, treatment group, dose escalation status (Y/N), time to respond, time to peak 
response, and duration of response will be provided in a listing.

Safety
Analysis of safety will be based on All Treated Subjects and presented by treatment (“as 
treated”) and overall.
Adverse events (AEs) will be coded according to the most current version of MedDRA and be 
graded using the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.
Drug-related AEs are those events with relationship to study drug “Related” as recorded on the 
CRF. If the relationship to study drug is missing, the AE will be considered as drug-related. 
Listing of adverse events will include all enrolled subjects as SAEs and deaths are collected 
pretreatment. Summaries of adverse events will include (1) events occurring from the first dose 
date to 35 days (inclusive) after the last dose of BMS-986004 for subjects who are off study

treatment and (2) all events occurring from first dose date for subjects who are still on study 
medication.
When reporting adverse events by CTC grade, summary tables will be provided based on the 
event with worst CTC grade (independent of relationship to study medication). Subjects will 
only be counted (1) once at the preferred term (PT) level, (2) once at the system organ class 
(SOC) level, and (3) once in the ‘Total subject’ row at their worst CTC grade, regardless of SOC 
or PT.
The analysis of laboratory results will be based on All Treated Subjects. Laboratory results will 
be categorized according to NCI CTCAE (version 4.0) grade. Baseline is defined as the last non-
missing measurement prior to the first dosing date and time. Summaries of laboratory results 
include baseline and (1) post-baseline results up to 35 days (inclusive) after the last dose of 
BMS-986004 for subjects who are off study treatment and (2) all available post-baseline results 
for subjects who are still on study medication.

Multiple Events
Analyses that take into account the multiple occurrences of a given adverse event will be 
conducted. In order to prepare these analyses, the CRF data will be processed according to 
standard BMS algorithms in order to collapse adverse event records into unique records based on 
the preferred term. This data will be presented as the rate per 100 patient-years of exposure. This 
analysis will take into account all on-treatment events (allowing more than 1 event per subject) 
and the total duration of exposure. The patient-years exposure will be computed as the sum over 
the subjects’ exposure expressed in years where the duration of exposure is defined as 

Date of last dose of study treatment - date of first dose of study treatment +35 + 1 days, for 
subject who are off study treatment and were followed at least 35 days after last dose of 
study medication.


PK Parameters
All individual PK parameters will be listed for BMS-986004 including any exclusions and 
reasons for exclusion from summaries. Summary statistics will be tabulated for each PK 
parameters by treatment and by study day. Geometric means and coefficients of variation will be 
presented for Cmax, AUC(TAU), CLT, AI_AUC, and AI_Cmax. Decimal place specifications 
for summary statistics are described in Section 7.11.
PK parameters will be summarized for day 1 and day 71 with the grouping decided by current 
dose - the planned dose on each of the two study days, as subjects are expected to have achieved 
steady state by day 71. Under this assumption, the PK parameters are considered to be related to 
the current dose, regardless of the previous doses. As such, 75mg dose group on day 71 consists 
of subjects dosed at 75mg only; 225mg dose group on day 71 consists of subjects from both non-
responders of 75mg cohort and responders of 225mg cohort, all of whom will be dosed at 
225mg; 675mg dose group on day 71 consists of subjects from both non-responders of 225mg 
cohort and responders of 675mg cohort; 1500mg dose group on day 71 consists all of the 
subjects from 1500mg cohort and also the non-responders from 675mg.
7.7.2
Ctrough Summary
Ctrough will be listed for all available data and summarized on day 15, 29, 43, 57, 71, and 85 for 
each group decided by previous dose.
7.7.3
Dose Proportionality
Dose proportionality will be provided separately for Cmax and AUC(TAU) on study day 1 and 
71 using a power model. Particularly, subjects going through dose escalation will be removed 
from the proportionality analysis for day 71. With the expected response rate of between 20% -
50% for 75mg, 225mg and 675mg, there would still be enough subjects left for the proportional 
analysis on day 71 after responders are removed. All subjects of 1500mg cohort will be included. 
In case there is no subject (all of the subjects are non-responders), or there are very few subjects 
(e.g., less than 3 subjects) in both 75mg and 225mg groups, dose proportionality analysis will not 
be provided for day 71. Decision will be data driven. Analysis results on day 71 will be 
discussed in the CSR if available; otherwise results on day 1 will be discussed.

The power model was described by Gough et al,1
PK Parameter = A*Doseβ. 
Parameter of the above model, β, will be estimated by the simple linear regression of  the natural 
log of the PK Parameter on the natural log of Dose:
E[log(PK Parameter)| Dose] = α + β*log(Dose).
For each PK parameter, the point estimate of slope β and its 90% CI will be provided. In 
addition, the estimated regression line will be overlaid on the individual points in the 
corresponding scatter plot (log-log scale).
A slope (β) equal to 1 would indicate perfect dose proportionality. However, as the study is
neither optimally designed nor powered to confirm the presence or absence of meaningful 
departures from dose proportionality, these results should be interpreted with caution.

Other Analysis
Subject serum concentration-time profiles will be listed and summarized by treatment and 
nominal collection time for BMS-986004. Plot of individual serum concentration profiles over 
time will be provided. Overlay of individual serum concentration profiles over time will be 
provided by treatment. Plots of mean (+SD) serum concentration profiles versus time will be 
presented for analyte, and all treatments will be superimposed on the same plot. Plots of mean 
(+SD) serum concentration profiles versus time will also be presented for each treatment, and all 
analytes will be superimposed on the same plot.

EmBARC (Enhanced Biometric Analysis & Reporting Capability) standard time windowing, 
imputation rules, and counting rules will be applied.

Decimal Places
The number of decimal places displayed in all listings will be determined by the number of 
decimal places in the raw data.  
Unless otherwise specified, minimum and maximum will be reported to the precision as the data 
collected, one more decimal place for the mean and median, and two more decimal places for the

standard deviation.  The adjusted geometric mean, geometric mean ratio and the lower and upper 
limits of confidence interval will be displayed to three decimal places.

Pharmacokinetic Summaries
In-text Tables
For in-text pharmacokinetic tables, coefficient of variation (%CV) will be reported as integers. 
For other statistics except for standard deviations, values of 100 or higher will be presented as 
integers, values of 10 - <100 will be displayed to one decimal place, and values of 1 - < 10 will 
be displayed to two decimal places. Values less than 1 will be displayed to three decimal places.  
Ratios will also be displayed to three decimal places. Standard deviations will be reported to a 
precision of 1 decimal place more than the mean.
Handling of Non-Quantifiable Concentrations2
For the summaries of serum concentration-time data, concentrations that are less than the lower 
limit of quantification (LLOQ) should be displayed as “< LLOQ” in the listings and be treated as 
missing in summary tables and plots.  For the purpose of calculating PK parameters, other than 
Ctrough, pre-dose concentrations that are less than LLOQ and concentrations prior to the first 
quantifiable concentration that are less than LLOQ will be set to zero, and all other 
concentrations less than LLOQ will be set to missing.
Summary statistics for Ctrough concentrations, analyses of PD-concentrations and ECG-
concentrations relationships will be calculated by imputing values less than LLOQ as ½ * 
LLOQ.  This imputation is done for Ctrough concentrations because it is treated like a PK 
parameter; the imputation is not done for Day 1 pre-dose concentrations.  Individual Ctrough 
listings will display these concentrations as “< LLOQ.”
All available serum concentration-time data and derived pharmacokinetic parameter values will 
be included in the PK data set and listed accordingly.
Treatment of Outliers
Individual serum concentrations, if deemed to be anomalous, may be excluded from the analysis 
following a review of available documentation (e.g., bioanalytical report, clinical data). Any 
such exclusion will be clearly listed in the study report along with justification for exclusion.
Entire serum concentration-time profiles for a subject may be excluded following review of 
available documentation (e.g., bioanalytical report, clinical data). However, results of analysis 
with and without the excluded profiles may be presented in the study report. Any such exclusion 
will be clearly listed in the study report along with justification for exclusion.
PK Exclusions2
PK Analysis, Reporting, and Exclusion criteria should following the BMS PK Harmonization 
document Version 2.0. Specific guideline for exclusionary criteria for half-life and how other PK 
parameters are affected for exclusion is under section 9.2 of the BMS PK Harmonization 
document.

Exclusion of one or more parameters or the entire dataset may be considered due to incomplete 
profile such as AUC(INF) or when T-HALF cannot be reliably calculated, or there is no sample 
around the suspected Cmax. In addition, subjects may be excluded from the analysis if they 
missed doses, had diarrhea, or vomited at or before a time equal to twice the median Tmax for 
immediate-release products, or vomited at any time during sampling after the administration of 
modified-release formulations.

CONTENT OF REPORTS
Statistical components for the clinical study report will be based on the content of this statistical 
analysis plan (SAP). It is assumed that a full CSR will be expected for the study IM140-103 at 
the writing of the SAP. If it is not the case, the SAP won’t be updated. Details of the tables, 
listings, and figures to be prepared for the CSR will be included in a study-specific Data 
Presentation Plan (DPP).
