Section 5.1: 
Overall Design
Updated first sentence in 
penultimate paragraph to: “In 
addition, if systolic BP is
< 85 mmHg or symptomatic 
hypotension occurs, the Principal 
Investigator (or designee; must be a 
medical doctor [MD]) must be 
contacted to make a decision as to 
whether an ambulatory unscheduled 
study visit or hospitalization is 
required based on overall clinical 
assessment. For example, 
asymptomatic study participants 
who can walk and have normal 
urination may not require 
hospitalization. BMS Study 
Director/Medical Monitor (or 
designee) must be notified.”
Clarified that primary investigator 
makes decisions on hospitalization for 
hypotension based on clinical 
judgement.
Section 5.5: 
Justification for 
Dose
Removed last paragraph and added 
text earlier in Section 5.5 to clarify 
dosing: “The observed mean 
exposures at steady state with 
repeated 3 mg QD dosing 
(AUC[TAU]) of 9,070 ng·h/mL 
remain under the mean exposure 
(AUC[INF]) of 38,200 ng·h/mL 
observed after a single 15 mg dose 
that was determined to be safe and 
well tolerated in a healthy 
participants study (Table 5.5-1).”

Clinical Protocol
CV019010
BMS-986259
FA-Relaxin
1
SYNOPSIS
Protocol Title:
A Randomized, Double-Blinded, Placebo-Controlled, Study to Evaluate the Safety and 
Tolerability of BMS-986259 in Stabilized Patients Hospitalized for Acute Decompensated Heart 
Failure
Short Title: Study of the safety of BMS-986259 post-acute decompensated heart failure
Study Phase: 2A 
Rationale:
The main purpose of this trial is to evaluate the effect of BMS-986259 on blood pressure (BP)
events defined as symptomatic hypotension or hypotension requiring study drug discontinuation, 
in hospitalized heart failure (HF) patients stabilized after an admission for acute decompensated 
HF (ADHF). The study is designed to provide data on the range of BP in which BMS-986259 is 
safe and well tolerated in the context of the current hospitalization for ADHF. It also aims to 
provide additional rationale for future development, future clinical use and to inform the design of 
the next Phase 2-3 studies. In addition, this study will provide initial data on the pharmacokinetics
(PK) of BMS-986259 in HF participants. 
Standard of care in the treatment of ADHF involves the use of intravenous (IV) loop diuretics and 
vasodilators, which may predispose participants to hypotension, with or without symptoms.
Current guidance also recommends continuing Guidelines Directed Medical Therapy (GDMT)
including angiotensin-converting enzymes (ACE), Beta-Blockers, mineralocorticoid receptor 
antagonists (MRA)/mineralocorticoid 
receptor 
inhibitors (MRI), 
and 
angiotensin 
receptor-neprilysin inhibitors (ARNI), which may also lower BP. In the Serelaxin ADHF study, 
RELAX-AHF, greater reductions from baseline in systolic blood pressure (SBP) were observed 
during IV infusion up to 48 hours in the serelaxin group (-16.5 mmHg ± 17.2) compared with 
placebo (-12.3 mmHg ± 17.2). Also, more participants on serelaxin than on placebo had protocol 
required BP-related dose reduction (29% vs 18%) or drug discontinuation (19% vs 12%). In 
contrast, in the chronic stable HF population of the RELAX REPEAT study, SBP in the serelaxin 
group did not differ from placebo. There are no data on the effect of relaxin on BP in the population 
of HF patients admitted for ADHF, but not yet discharged, already medically stabilized and 
weaned from IV vasodilators or inotropes. 
Study Population:
Male and females, at least 18 years of age or local age of majority, currently hospitalized for 
ADHF, regardless of left ventricular ejection fraction (LVEF).

Objectives and Endpoints:
Objective
Endpoint
Primary
•
To establish safety & tolerability of 
BMS-986259 when initiated 
in-hospital in participants stabilized
after an admission for ADHF
•
Incidence of clinically relevant hypotension, defined as:
−
Supine SBP < 85 mmHg (confirmed by repeat 
measurement within 30 minutes), regardless of symptoms 
of hypotension 
OR
−
Supine SBP < 90 mmHg (confirmed by repeat measurement 
within 30 minutes) AND symptoms of hypotension.
Secondary
•
To evaluate serum PK parameters in 
participants with HF 
•
PK parameters of BMS-986259:
−
Cmax, Tmax, and AUC(TAU) on Day 1 and Day 5
−
Ctrough
Abbreviations: ADHF = acute decompensated heart failure; AUC(TAU) = area under the concentration-time curve in 
one dosing interval; BMS = Bristol-Myers Squibb; Cmax = maximum observed concentration; Ctrough = trough 
concentration; HF = heart failure; PK = pharmacokinetic; SBP = systolic blood pressure; Tmax = time of maximum 
observed concentration.
Overall Design:
This is a Phase 2A randomized, double-blind, placebo-controlled study of BMS-986259 in 
hemodynamically stabilized patients currently hospitalized for ADHF. The study is designed to 
establish if BMS-986259 is safe and well tolerated in this population with regards to clinically 
significant hypotension.
•
ADHF must be the main reason for hospitalization, and other conditions with similar signs and 
symptoms must be excluded at screening.
•
at least 24 hours after presentation to Emergency Room (ER) and no later than 8 days after 
presentation to ER. Time of the presentation is defined as the time of the first dose of IV 
diuretic in the hospital. Randomization must occur within a maximum of 8 days since 
presentation to ER and before hospital discharge.
•
at least 12 hours since last dose change of IV loop diuretics and at least 24 hours since last 
dose of positive inotropes and ≥ 12 hours since the last dose of IV vasodilators.
•
Prior to randomization, participants will also be tested for severe acute respiratory syndrome 
coronavirus 2 by reverse transcription polymerase chain reaction or rapid antigen test. Only 
participants with a negative test result are eligible for randomization.
Participants will be randomized 1:1 to receive BMS-986259 3 mg or placebo. Treatment will be 
administered subcutaneously once daily for 14 days and follow-up will last until Day 30 (± 2 days).

A minimum hospital stay of 5 days from randomization/first dose of investigational product (IP)
is required. If participants are discharged home before the end of active study treatment, study 
visits will be performed daily either as an outpatient clinic visit or by a home nurse or healthcare 
provider (per local regulations/requirements) who will be responsible to measure pre-dose BP, 
draw PK sample(s), administer the IP subcutaneously
 
when appropriate per study schedule.
Participants will return for up to three ambulatory visits at the site on Day 8, Day 14, Day 30 
(follow-up). If the participant cannot return to the site because of coronavirus disease 2019 
(COVID-19) local regulations that prevent visits in-person, these visits can be done at home by 
the home nurse in discussion with the Principal Investigator (or designee). In addition, at discharge, 
participants will receive BP measuring device and will be instructed to measure BP if symptoms 
consistent with hypotension occur. If systolic BP falls below 85 mmHg (on 2 repeated 
measurements within 30 minutes) and symptoms of hypotension persist, participants will be 
instructed to report to the study site or another healthcare provider if the study site cannot be 
reached.
Initially participants with SBP ≥115 mmHg will qualify to be randomized 1:1 to receive 3 mg 
subcutaneous BMS-986259 once daily (QD) or placebo. After approximately 8 participants with 
SBP ≥115 and < 130 mmHg have completed the treatment period, the Safety Review Committee 
will review the safety data from this sentinel group and ensure it is safe to proceed with the 
Main Group, ie., open the recruitment for participants with SBP less than 115 mmHg (but at least 
100 mmHg).
The Main Group will include participants with SBP ≥100 mmHg, randomized 1:1 to BMS-986259 
or placebo. The proportion of participants with SBP > 125 mmHg will be capped at 48 participants.
Study drug may be down-titrated to 1 mg or discontinued according to the criteria described in 
dose modification.
In addition, if systolic BP is < 85 mmHg or symptomatic hypotension occurs, the Principal 
Investigator (or designee; must be a medical doctor [MD]) must be contacted to make a decision 
as to whether an ambulatory unscheduled study visit or hospitalization is required based on overall 
clinical assessment. For example, asymptomatic study participants who can walk and have normal 
urination may not require hospitalization. BMS Study Director/Medical Monitor (or designee) 
must be notified. A blinded clinical contact will be available 24/7 to answer questions and guide 
the home nurse as needed.

INTRODUCTION
Heart failure (HF) is a clinical syndrome that results from insufficient supply of blood to maintain 
normal tissue function due to any structural or functional impairment of ventricular filling or 
ejection of blood from the heart. The cardinal manifestations of HF are dyspnea and fatigue, which 
may limit exercise tolerance and promote fluid retention, leading to pulmonary and/or splanchnic 
congestion and/or peripheral edema.1 The global burden of HF is substantial with an estimated 
global prevalence of 26 million. In the United States alone, an estimated 6.5 million people suffer 
from HF, a number that is projected to increase ~ 46% by the year 2030.2,3 Current treatment 
guidelines categorize HF patients based on ejection fraction (EF): 1) heart failure with reduced 
ejection fraction (HFrEF) with an EF ≤40%, 2) heart failure with a mid-range (intermediate) 
ejection fraction (HFmrEF) of 41% to 49%, and 3) heart failure with preserved ejection fraction 
(HFpEF) with an EF ≥50%.1 The pathophysiology of HF is highly complex and diverse in 
etiology, especially with regard to the biological pathways that lead to either HFrEF or HFpEF.4,5,6
Although therapeutics which target the neurohormonal axis (eg, beta-blockers, angiotensin 
converting enzyme inhibitors and other renin angiotensin-aldosterone system (RAAS) inhibitors, 
as well as mineralocorticoid receptor antagonists [MRAs]) have led to a decrease in mortality rates 
in HFrEF patients, unmet medical need remains very high.7 No therapy has yet been proven in a 
placebo-controlled clinical trial to reduce mortality rates in HFpEF patients.7
HF is commonly accompanied by multiple comorbidities including hypertension, diabetes 
mellitus, and chronic kidney disease (CKD).5 The majority of HF patients have CKD, defined as 
an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73 m2.8 A large meta-analyses of 
80,098 hospitalized and non-hospitalized HF patients revealed that the presence of CKD is highly 
prognostic of worsening HF.9 Furthermore, worsening renal function (WRF) during the 1-year 
period following hospital discharge for acute decompensated HF (ADHF) was a strong predictor 
of all-cause mortality.10 These types of associative data combined with biological plausibility, in 
that renal impairment can lead to a feedback response of neurohormonal and RAAS activation, 
have led some investigators to suggest that CKD may play a causal role in HF.9 However, whether 
or not CKD is truly on the causal pathway to worsening HF is unknown. 
Human relaxin (H2-relaxin) is a peptide hormone believed to be, at least in part, responsible for 
the many physiological adaptations that occur during human pregnancy.11 These changes include

an ~ 30% increase in global arterial compliance which is important to maintain efficient 
ventricular-arterial coupling, an ~ 30% decrease in total systemic vascular resistance (SVR), and 
up to an 80% and 50% increase in renal blood flow (RBF) and glomerular filtration rate (GFR), 
respectively.12,13,14 As discussed in detail below, clinical studies in which serelaxin was 
administered intravenously (IV) to either normal healthy volunteers (NHV) or HF patients 
provided pharmacological evidence that H2-relaxin is involved, at least in part, in mediating these 
adaptive maternal changes. Because H2-relaxin activates both relaxin/insulin-like family peptide 
receptor 1 (RXFP1) and relaxin/insulin-like family peptide receptor 2 (RXFP2) it has been difficult 
to precisely define the individual roles of each receptor during mammalian pregnancy. However, 
several lines of evidence, including the noted receptor potency differential in relationship to low 
endogenous blood levels of H2-relaxin during human pregnancy, tissue expression patterns, and 
arterial compliance experiments in vessels that express RXFP1, but not RXFP2, all suggest that 
RXFP1 plays the larger role of the 2 receptors.15,16 There are no reports in the literature describing 
loss-of-function mutations in humans for either the H2-relaxin or the RXFP1 gene. In contrast, 
missense mutations in either the human insulin-like peptide 3 (INSL3) or the RXFP2 gene are 
associated with cryptorchidism, indicating that activation of RXFP2 plays a critical role in 
testicular descent, which normally occurs at gestational week 24 through 34 in humans.17 The 
physiological effect, if any, of RXFP2 activation in the adult human is unknown.
A short-acting recombinant form of H2-relaxin, serelaxin- (Novartis), administered IV, was 
demonstrated to have vasodilatory properties and to enhance both RBF and eGFR in patients with 
HF.18,19,20 Serelaxin also demonstrated anti-fibrotic activity in cell-based and in preclinical models 
of fibrosis.21,22 In a large Phase 3 clinical trial (RELAX-AHF-2), serelaxin, when administered as 
a short-term 48-hour continuous IV infusion, failed to improve long-term clinical outcomes 
compared with placebo in patients with ADHF.23 Although this failure represents a setback for the 
advancement of novel therapeutics to treat HF, learnings from the multitude of serelaxin clinical 
trials, indicate that chronic administration of a therapeutic with H2-relaxin-like activity (ie, beyond 
48 hours) could potentially benefit HF patients. More specifically, serelaxin was demonstrated to 
increase both RBF and eGFR in NHV and HF patients.18,19,20,24,25 In a non-placebo-controlled 
trial, when serelaxin- was administered IV to NHV over a 5-hour period at a dose resulting in 
blood concentrations that closely mimicked the peak human pregnancy blood concentration of 
H2-relaxin (1.0 ng/mL), a 47% increase, relative to baseline, in RBF was observed, although GFR 
remained unchanged.24 Changes in RBF were similar between males and females. In a separate 
double-blind, placebo-controlled, dose-ranging study in NHV of Japanese descent, serelaxin was 
given as a continuous 48-hour IV infusion at doses of 10, 30, or 100 μg/kg/day.25 Mean blood 
concentrations of serelaxin at the 48-hour time point were 3.49 ng/mL, 9.82 ng/mL, and 
29.2 ng/mL, respectively. Statistically significant increases in eGFR were observed for all doses 
of serelaxin, but not for placebo. Changes in RBF were not evaluated in this study. In a 
double-blind and placebo-controlled study in chronic HF patients, when compared to placebo, 
statistically significant increases in renal plasma flow were observed for serelaxin when given as 
a continuous 24-hour IV infusion at a dose of 30 μg/kg/day.18 Changes in GFR were minimal and

not significantly different from placebo. In a separate double-blind and placebo -controlled study 
in which serelaxin was given to chronic HF patients as a continuous 48-hour IV infusion at the 
dose of 30 μg/kg/day, when compared to placebo, statistically significant increases in eGFR 
(difference of 4.7, 5.9 and 5.7 ml/min/1.73m2 vs placebo, at 2, 4 and 8 weeks; p<0.001) were 
observed for serelaxin.19 Plasma concentrations of aldosterone were decreased in the serelaxin 
treatment group, but not in the placebo treatment group indicating that enhancement of renal 
function in chronic HF patients may lead to attenuation of RAAS activation.
Hemodynamic effects of serelaxin were also studied in a double-blind, placebo-controlled trial in 
patients hospitalized for ADHF. When serelaxin was given as a 20-hour IV infusion at a dose of 
30 μg/kg/day, hemodynamic effects were detected early (within 30 minutes), and were 
characterized by statistically significant reductions (versus placebo) in pulmonary capillary wedge 
pressure (PCWP) and pulmonary arterial pressure (PAP), with a concomitant decrease in SVR.20
Serelaxin administration also improved renal function and decreased circulating levels of 
N-terminal pro-brain natriuretic peptide (NT-proBNP), a biomarker of cardiac stress. 
Several investigators, through the use of subcutaneous (SC) osmotic mini-pumps which 
continuously deliver drug at a defined rate, demonstrated that treatment with H2-relaxin decreased 
fibrosis in various rodent models of cardiac, kidney, lung and liver fibrosis.21 In a cell-based model 
of TGF-β-treated rat cardiac fibroblasts, serelaxin significantly decreased expression of the pro-
fibrotic genes smooth muscle alpha-actin and collagen type I.22 Changes in levels of protein 
phosphorylation indicated that the reduction in pro-fibrotic gene expression was the result of 
serelaxin-dependent suppression of activin-like kinase 5 (ALK5)/Mothers against decapentaplegic 
homolog 2 (SMAD2) signaling, a well-studied signaling pathway induced by TGF-β.
The ability of H2-relaxin/serelaxin to positively impact both systemic and renal hemodynamics, 
improve renal function, and possibly decrease cardiac fibrosis, makes H2-relaxin an attractive 
candidate as a chronic therapy for HF patients. However, the short-acting PK profile of H2-relaxin 
essentially precludes its use as a chronic therapeutic. In contrast, with a PK profile (non-clinical 
studies and preliminary clinical data) that supports once daily (QD) dosing and H2-relaxin-like 
activity, BMS-986259 represents an opportunity to provide HF patients with the therapeutic 
benefits anticipated for H2-relaxin when dosed chronically.
3.1
Study Rationale
The main purpose of this trial is to evaluate the effect of BMS-986259 on blood pressure (BP)
events defined as symptomatic hypotension or hypotension requiring study drug discontinuation, 
in hospitalized HF patients stabilized after an admission for ADHF. The study is designed to 
provide data on the range of BP in which BMS-986259 is safe and well tolerated in the context of 
the current hospitalization for ADHF. It also aims to provide additional rationale for future 
development, future clinical use and to inform the design of the next Phase 2-3 studies. In addition,
this study will provide initial data on the pharmacokinetics of BMS-986259 in HF participants. 
Standard of care in the treatment of ADHF involves the use of IV loop diuretics and vasodilators, 
which may predispose participants to hypotension, with or without symptoms. Current guidance

also recommends continuing Guidelines Directed Medical Therapy (GDMT)
including 
angiotensin-converting enzymes (ACE), beta-blockers, MRAs/mineralocorticoid receptor 
inhibitors (MRI), and angiotensin receptor-neprilysin inhibitors (ARNI), which may also lower 
BP. In the Serelaxin ADHF study, RELAX-AHF, greater reductions from baseline in SBP were 
observed during IV infusion up to 48 hours in the serelaxin group (-16.5 mmHg ± 17.2) compared 
with placebo (-12.3 mmHg ± 17.2). Also, more participants on serelaxin than on placebo had 
protocol required blood pressure-related dose reduction (29% vs 18%) or drug discontinuation 
(19% vs 12%).26 In contrast, in the chronic stable HF population of the RELAX REPEAT study,
SBP in the serelaxin group did not differ from placebo.19 There are no data on the effect of relaxin
on BP in the population of HF patients admitted for ADHF, but not yet discharged, already 
medically stabilized and weaned from IV vasodilators or inotropes. 
3.2
Background
Over the last several decades, the improvements in HF treatments led to better survival and reduced 
hospitalization rate in patients with HFrEF. Current HF guidelines however recognize that this
outcome is still not satisfactory. In the recent European data, 12-month all-cause mortality rate for 
hospitalized and stable ambulatory HF patients were 17% and 7%, respectively and hospitalization 
rates were 44% and 32%, respectively.27 In addition, optimization of the evidence-based 
treatments is often limited by co-morbidities and undesired effects of treatment such as renal 
impairment, hyperkalemia, and low blood pressure, typical for RAAS blocking agents remaining 
the foundational therapy for HFrEF. In addition, no beneficial effects on outcomes were 
demonstrated with similar strategies in patients with HFpEF. Hence, new approaches are required
to improve outcomes both in HFpEF as well as in patients with HFrEF, when optimization of 
therapy is particularly difficult.28
Several studies with recombinant human relaxin have demonstrated short-term multi-organ 
protection in HF patients measured as beneficial effects on biomarkers of cardiac and renal injury 
and improved function. The half-life of serelaxin is short after acute 48 hours infusion and long-
term improvement in CV outcomes has not been seen. Short-term IV injection cannot be expected 
to exhibit lasting effects; therefore, to fully understand the potential long-term benefits of relaxin, 
one needs to develop a formulation that allows for chronic administration.
BMS-986259, is a recombinant form of H2-relaxin that contains a covalently attached fatty acid 
which binds to circulating albumin, extending its half-life. BMS-986259 closely mimicked the 
activity profile of H2-relaxin in a panel of in vitro cell-based assays, as well as in a rodent 
pharmacodynamic in vivo model.29 These activity data, together with the preclinical PK and 
toxicology data, indicate that BMS-986259 can be safely administered subcutaneously. 
Preliminary data from ongoing first in human (FIH) study also support safe subcutaneous use up 
to 14 days. Chronic QD subcutaneous (SC) administration of BMS-986259 has the potential to 
benefit patients with HF. An ongoing Phase 1 study with BMS-986259 will confirm its effects on 
the renal function and support its potential to protect/improve renal function in HF.

The population of ADHF patients, early after admission, has the highest rate of 60 to 90 days
mortality and rehospitalizations, with rates as high as 14% and 30%, respectively.30 In the United 
States alone, there are more than 1 million admissions for HF as primary diagnosis per year.31,32
This represents a high unmet need for both patients with HFrEF and HFpEF. In the ADHF 
population, little to no data are available about the benefits of starting chronic treatment in the 
hospital setting, before discharge. 
3.3
Benefit/Risk Assessment
The current study is a Phase 2A, multicenter, randomized, double-blind, placebo-controlled, 
parallel-group study of BMS-986259 in medically stabilized participants currently hospitalized for 
ADHF. Participants will continue their therapy as deemed necessary for their condition and receive 
any HF therapy required by HF guidelines. Participants may benefit from an ongoing assessment 
of their health status in the period of time immediately after discharge from the hospital. It is not 
known if 2 weeks of therapy with BMS-986259 can provide any symptomatic improvement and 
50% of participants will receive placebo. Short -term course of BMS-986259 is not expected to 
translate into long-term benefit. 
In the ongoing Phase 1 study in NHV (CV019-002), BMS-986259’s administration was generally 
safe and well-tolerated. The most frequently reported adverse events (AEs) were cannula site 
reaction and cannula site pain related to the study procedures to measure RBF and GFR, but 
unrelated to the study drug. The effect on BP and heart rate (HR) in individual participants appears 
to be minimal. Formal statistical summaries are not available at this time as the treatment is still 
blinded, but no clinically significant or symptomatic hypotension has been reported. The doses 
evaluated thus far have been safe and well-tolerated, with no deaths, serious adverse events 
(SAEs), or AEs leading to discontinuation reported. In the large serelaxin development program,
human recombinant relaxin was generally safe and well tolerated in participants with HF. 
Bristol-Myers Squibb (BMS) nonclinical and preliminary clinical data and the serelaxin clinical 
program suggest that the principal risk associated with the use of BMS-986259 is hypotension. 
Transient reductions in BP are not expected to be associated with long-term sequelae. This study 
is designed specifically to address this risk, and mitigation strategies are implemented, such as 
rigorous BP monitoring, both in-hospital and post-discharge, and a dose-modification algorithm 
in case of symptomatic or asymptomatic hypotension.

Investigational Product-related Risk
At this time, BMS is tracking and accumulating data on COVID-19 and its potential effects on 
participants taking BMS-986259 and other investigational products (IPs). The data are analyzed 
on a regular basis. Based on its properties and mechanism of action, BMS-986259 is not believed 
to be implicated in COVID-19 infection and symptomology. The risk of COVID-19 in participants 
taking BMS-986259 is still unknown due to insufficient clinical data.
3.3.1.2
General COVID-19-related Risk Mitigation Measures
General risk mitigation for COVID-19 will be implemented in accordance with the sites’ local 
prevention control procedures
and relevant governmental and Institutional Review 
Board (IRB)-associated requirements. Such measures aim to minimize prevalence and 
transmission of SARS-CoV-2 among site staff and participants and include distancing, 
sanitization, use of personal protective equipment, and testing.
Participants found to test positive for SARS-CoV-2 after enrollment in the study will be treated 
according to site standard practice and in accordance with local and national regulations. In such 
cases, treatment with BMS-986259 will be discontinued as described in Section 8.
The risk mitigation measures are part of the protocol-specific informed consent form (ICF), and 
when and where applicable, will be amended based on emerging guidance.

symptoms must be excluded at screening.
•
at least 24 hours after presentation to Emergency Room (ER) and no later than 8 days after
presentation to ER. Time of the presentation is defined as the time of the first dose of IV 
diuretic in the hospital. Randomization must occur within a maximum of 8 days since 
presentation to ER and before hospital discharge.

at least 12 hours since last dose change of IV loop diuretics and at least 24 hours since last

Prior to randomization, participants will also be tested for SARS-CoV-2 by reverse 
transcription polymerase chain reaction (RT-PCR) or rapid antigen test. Only participants with 
a negative test result are eligible for randomization.
Participants will be randomized 1:1 to receive BMS-986259 3 mg or placebo. Treatment will be 
administered subcutaneously once daily for 14 days and follow-up will last until Day 30 (± 2 days). 
A minimum hospital stay of 5 days from randomization/first dose of IP is required. If participants 
are discharged home before the end of active study treatment, study visits will be performed daily 
either as an outpatient clinic visit or by a home nurse or healthcare provider (per local 
regulations/requirements) who will be responsible to measure pre-dose BP, draw PK sample(s), 
administer the IP subcutaneously
 
.
Participants will return for up to three ambulatory visits at the site on Day 8, Day 14, Day 30
(follow-up). If the participant cannot return to the site because of COVID-19 local regulations that 
prevent visits in-person, these visits can be done at home by the home nurse in discussion with the 
Principal Investigator (or designee). In addition, at discharge, participants will receive BP 
measuring device and will be instructed to measure BP if symptoms consistent with hypotension 
occur. If systolic BP falls below 85 mmHg (on 2 repeated measurements within 30 minutes) and 
symptoms of hypotension persist, participants will be instructed to report to the study site or 
another healthcare provider if the study site cannot be reached. 
Initially participants with SBP ≥115 mmHg will qualify to be randomized 1:1 to receive 3 mg 
subcutaneous BMS-986259 QD or placebo. After approximately 8 participants with 
SBP ≥115 and < 130 mmHg have completed the treatment period, the Safety Review Committee 
will review the safety data from this sentinel group and ensure it is safe to proceed with the 
Main Group, ie., open the recruitment for participants with SBP less than 115 mmHg (but at least 
100 mmHg). 
The Main Group will include participants with SBP ≥100 mmHg, randomized 1:1 to BMS-986259 
or placebo. The proportion of participants with SBP > 125 mmHg will be capped at 48 participants.
Study drug may be down-titrated to 1 mg or discontinued according to the criteria described in 
dose modification in Section 7.4.
In addition, if systolic BP is < 85 mmHg or symptomatic hypotension occurs, the Principal 
Investigator (or designee; must be a medical doctor [MD]) must be contacted to make a decision

5.4
Scientific Rationale for Study Design
Relaxin exhibits vasodilatory effect and BMS-986259 is expected to demonstrate similar 
properties including potential for lowering blood pressure. Serelaxin’s development program 
provided extensive data in patients treated for ADHF. Small difference from placebo was observed 
in the absolute SBP lowering, however a substantially larger proportion of patients demonstrated 
clinical AEs related to BP reduction. In the RELAX-AHF study, confirmed events of decreased 
blood pressure were reported in 18% and 29% in the placebo vs the active group, respectively.26
In contrast, in the RELAX-REPEAT study conducted in chronic stable HF patients, there was no 
observed difference in blood pressure between serelaxin and placebo.19 No data are available on 
the risk of clinically significant hypotension with relaxin administered to medically stabilized 
patients admitted for ADHF, especially in the group with SBP < 125 mmHg which was an 
exclusion criterion in the serelaxin program. Hypotension is one of the factors prohibiting 
treatment optimization with standard of care HF medications; thus, a new treatment that would be 
safe and well tolerated in patients with lower range of BP would be clinically valuable. This study 
will allow to establish safety and tolerability of BMS-986259 with regards to the risk of 
hypotension in such population. The population of HF patients early after admission for ADHF 
has the highest rates of mortality and rehospitalization, with the rates as high as 14% and 30% 
within 60 to 90 days, respectively.30 This represents a high unmet need for both patients with 
HFrEF and HFpEF. 
The duration of the study is limited by the availability of the current toxicology data (up to 
2 weeks). The primary goal of the study is safety and tolerability. Fourteen days should be 
sufficient to establish potential for hypotension to inform further development BP margins and 
help to inform the design of Phase 2 / Phase 3 studies. Based on the data from the ongoing Phase 
1 trial, steady state is achieved after approximately 5 days. Study duration will allow to observe 
participants after they achieved steady state and a minimum hospital stay of 5 days after 
randomization will ensure more intense monitoring while the exposures of the study drug are still 
increasing.

The secondary 
 efficacy endpoints include PK
 
 which will provide an initial supportive data for the mechanism of action in 
heart failure population. 
Finally, serum PK will be measured to validate data collected from Phase 1 in normal healthy 
volunteers and further inform dosing in Phase 2.
5.5
Justification for Dose
The planned dose for this study (3 mg) has been selected as a pharmacologically active and safe 
dose, likely to be further studied in Phase 2B, thus safety/tolerability data collected in this study 
will inform design of the Phase 2B study. The BMS‑986259 dose selected for this study (3 mg) 
was associated with improvement in RBF after single and multiple doses in normal healthy 
participants (up to 46% increase in RBF).The 3 mg multiple doses in FIH study were also safe and 
well tolerated by the healthy participants. 
In the FIH study (CV019002), single doses as much as 5-fold higher (15 mg) have been safely 
administered to healthy participants. The observed mean exposures at steady state with repeated
3 mg QD dosing (AUC[TAU]) of 9,070 ng h/mL remain under the mean exposure (AUC[INF]) of 
38,200 ng h/mL observed after a single 15 mg dose that was determined to be safe and well 
tolerated in a healthy participants study (Table 5.5-1). 
Based on preliminary results, single dose exposures (Cmax and area under the concentration-time 
curve [AUC]) increased in a dose-proportional manner with increasing dose. With multiple doses 
of 1 mg and 3 mg QD for 14 days, up to 2.5-fold (1 mg) and 2.7-fold (3 mg) accumulation of Cmax 
and AUC(TAU) were observed on Day 14 versus Day 1, with steady-state reached within 
approximately 5 days based on trough concentrations. The geometric mean Cmax and AUC values 
observed with a single 15 mg dose and a 3 mg QD dose are listed in Table 5.5-1.

A short‑acting recombinant form of human H2-relaxin, serelaxin, dosed IV, demonstrated 
vasodilatory properties and enhanced both RBF and eGFR in patients with HF.18,19,20 In previous 
studies, serelaxin was safely administered IV for up to 48 hours in healthy participants and over 
4,000 patients with HF and produced increases in RBF and GFR, as well as improvements in 
multiple hemodynamic parameters and biomarkers of cardiac and renal function. 18,19,20,23,24,25,26
Based on the potency ratio between serelaxin and BMS-986259, it is anticipated that the 3 mg dose 
of BMS-986259 is consistent with the doses found to be efficacious, safe and well tolerated in 
heart failure patients in the serelaxin development program.

The time of dose administration of the first dose will be called “0” hour for serum PK reporting.
7.2
Method of Treatment Assignment
All participants will be centrally randomized using an Interactive Response Technology (IRT). 
Before the study is initiated, each user will receive log in information and directions on how to 
access the IRT.
Study treatment will be dispensed at the Day 1 visit.
At the time of screening for both the Sentinel Group and Main Group, participants will be 
randomized to receive either BMS-986259 or placebo in a 1:1 ratio according to a computer-
generated randomization scheme prepared by a Randomization Coordinator within the Drug 
Supply Management Department of BMS Research and Development. 
Enrolled participants, including those not dosed, will be assigned sequential participant numbers 
starting with 00001, (eg, 00001, 00002, 00003.... 00010). Sequential numbering may restart at 
00001 for each participating site as the distinct patient identification number (PID) will ultimately 
be comprised of the site number and participant number, (eg, 0002 00001). Those enrolled 
participants meeting inclusion and exclusion criteria will be eligible to be randomized. 
Randomization numbers will be assigned prior to dosing. 
During the screening visit, the investigative site will call into the enrollment option of the 
Interactive Response Technology (IRT) designated by BMS for assignment of a 5-digit participant
number that will be unique across all sites. For example, the first participant screened (ie, enrolled) 
at site number 1, will have a PID of 0001 00001. Once it is determined that the participant meets 
the eligibility criteria following the screening visit, the investigative site will call the IRT to 
randomize the participant.

7.3
Blinding
Blinding of treatment assignment is critical to the integrity of this clinical study. However, in the 
event of a medical emergency or pregnancy in an individual participant in which knowledge of the 
IP is critical to the participant's management, the blind for that participant may be broken by the 
investigator. The participant’s safety takes priority over any other considerations in determining if 
a treatment assignment should be unblinded.
Before breaking the blind of an individual participant's treatment, the investigator should 
determine that the unblinded information is necessary, ie, that it will alter the participant's 
immediate management. In many cases, particularly when the emergency is clearly not related to 
the IP, the problem may be properly managed by assuming that the participant is receiving active 
product. It is highly desirable that the decision to unblind treatment assignment be discussed with 
the BMS Study Director / Medical Monitor (or designee), but the investigator always has ultimate 
authority for the decision to unblind. The actual TASK of unblinding can be delegated by the 
investigator to a designee assigned the task on the Delegation of Authority. The Principal 
Investigator or appointed designee should only call in for emergency unblinding AFTER the 
decision to unblind the participant has been documented. 
For this study, the method of unblinding for emergency purposes is via the Interactive Response 
Technology (IRT) system. For information on how to unblind in an emergency, consult the IRT 
manual.
In cases of accidental unblinding, contact the BMS Study Director / Medical Monitor (or designee) 
and ensure every attempt is made to preserve the blind. 
Any request to unblind a participant for non-emergency purposes should be discussed with the 
BMS Study Director / Medical Monitor (or designee).
Except as noted below, members of BMS Research and Development personnel involved in the 
study conduct and evaluation, as well as all vendors responsible for the conduct of the trial 
(protocol team) will remain blinded.
A bioanalytical scientist in the Bioanalytical Sciences department of BMS Research & 
Development (or a designee in the external central bioanalytical laboratory) will be unblinded to 
(may obtain) the randomized treatment assignments in order to minimize unnecessary 
bioanalytical analysis of samples as PK will not be analyzed placebo samples.
An internal Safety Review Committee, independent from the study team, will assess BP data after 
completion of approximately 8 participants randomized with SBP ≥ 115 mmHg and < 130 mmHg 
in the Sentinel Group. The internal Safety Review Committee will also assess safety results, 
including hypotension, from the planned interim analysis (IA; Section 10.3.5).
For the assessment of BP data in the Sentinel Group and for the planned IA, an unblinded 
statistician and programmer(s), separate from the study team, will be performing the required 
safety analyses for the internal Safety Review Committee. The internal Safety Review Committee 
may require access to unblinded treatment codes for individual participants. Additional designated

Dosage Modification
Any decision to decrease the dose level of study drug or discontinue study drug should be based 
on the investigator’s assessment of the participants’ clinical stability and in the overall context of 
the participant’s condition. A dose reduction to 1 mg is allowed if certain criteria are met, as 
described in the section below. Study drug may be also permanently discontinued early as 
described in the following section.
7.4.1
Dose Down-titration
•
On Days 1 through 6, if the participant experiences SBP < 85 mmHg without symptoms related 
to hypotension, the measurement must be repeated in 30 minutes. If the SBP remains 
< 85 mmHg the next day’s study drug administration should be skipped and dosing should 
resume at 1 mg, the following day, if SBP is ≥85 mmHg (ie, after a 1-day drug “holiday”, the 
treatment will resume at a reduced dose).
•
On Days 1 through 6, if the participant experiences SBP < 90 mmHg and symptoms of 
hypotension (such as dizziness, light headedness etc), the measurement must be repeated in 
30 minutes. If the SBP remains < 90 mmHg the next day’s study drug administration should 
be skipped and dosing should resume at 1 mg, the following day, if SBP is ≥85 mmHg and 
symptoms of hypotension resolved (ie, after a 1-day drug “holiday”, the treatment will resume 
at a reduced dose).
•
On Days 1 through 6, if the participant experiences SBP fall ≥40 mmHg with symptoms of 
hypotension that in the opinion of investigator preclude further safe dosing of the participant 
at the initial dose level, the next day’s study drug administration should be skipped and dosing 
should resume at 1mg the following day, if SBP is ≥85 mmHg and symptoms of hypotension 
resolved (ie, after a1-day drug “holiday”, the treatment will resume at a reduced dose).
•
After dose reduction, the dose cannot be increased again.
7.4.2
Permanent discontinuation of the study drug
•
If the participant experiences SBP < 85 mmHg regardless of symptoms of hypotension, or 
symptomatic hypotension with SBP < 90 mmHg (measurements must be repeated in 30 
minutes), despite dose reduction, then the study drug must be discontinued.
•
On Days 7 through 14, if the participant experiences SBP < 85 mmHg regardless of symptoms 
of hypotension, the measurement must be repeated in 30 minutes. If the SBP remains 
< 85 mmHg, the study drug should be discontinued.
•
On Days 7 through 14, if the participant experiences SBP < 90 mmHg and symptoms of 
hypotension (such as dizziness, lightheadedness, etc), the measurement must be repeated in 
30 minutes. If the SBP remains < 90 mmHg, the study drug should be discontinued.

Preparation/Handling/Storage/Accountability
The IP should be stored in a secure area according to local regulations. It is the responsibility of 
the investigator to ensure that IP is only dispensed to study participants. The IP must be dispensed 
only from official study sites by authorized personnel according to local regulations.
The product storage manager should ensure that the study treatment is stored in accordance with 
the environmental conditions (temperature, light, and humidity) as determined by BMS. If 
concerns regarding the quality or appearance of the study treatment arise, the study treatment
should not be dispensed and contact BMS immediately.
Study treatment not supplied by BMS will be stored in accordance with the package insert.
IP documentation (whether supplied by BMS or not) must be maintained that includes all processes 
required to ensure drug is 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).
For study drugs not provided by BMS and obtained commercially by the site, storage should in 
accordance with the product label.

Discontinuation from the Study
Participants who request to discontinue study treatment 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 
participant specifically withdraws consent for any further contact with him/her or persons 
previously authorized by participant to provide this information. 
•
Participants 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 treatment 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 participant 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.
•
If the participant withdraws consent for disclosure of future information, the sponsor may 
retain and continue to use any data collected before such a withdrawal of consent.
8.3
Lost to Follow-Up
•
All reasonable efforts must be made to locate participants to determine and report their ongoing 
status. This includes follow-up with persons authorized by the participant.
•
Lost to follow-up is defined by the inability to reach the participant after a minimum of three
documented phone calls, faxes, or emails as well as lack of response by participant to one 
registered mail letter. All attempts should be documented in the participant’s medical records.
•
If it is determined that the participant has died, the site will use permissible local methods to 
obtain date and cause of death.
•
If investigator’s use of third-party representative to assist in the follow-up portion of the study 
has been included in the participant’s informed consent, then the investigator may use a 
Sponsor retained third-party representative to assist site staff with obtaining participant’s

Investigator Assessment of Signs and Symptoms
New York Heart Association (NYHA) class will be evaluated by the investigator on Day 1, at 
discharge, and on Day 14 and Day 30. (See Appendix 6)
9.2
Adverse Events
The definitions of an AE or SAE can be found in Appendix 3.
AEs will be reported by the participant (or, when appropriate, by a caregiver, surrogate, or the 
participant's legally authorized representative). 
The investigator and any designees are responsible for detecting, documenting, and reporting 
events that meet the definition of an AE or SAE and remain responsible for following up AEs that 
are serious, considered related to the study treatment or the study, or that caused the participant to 
discontinue before completing the study. 
Contacts for SAE reporting specified in Appendix 3
9.2.1
Time Period and Frequency for Collecting AE and SAE Information
Appendix 1 in the Investigator’s Brochure (IB) represent the Reference Safety Information to 
determine expectedness of SAEs for expedited reporting.
All SAEs must be collected from the time of signing the consent, including those thought to be 
associated with protocol-specified procedures and within 30 days of discontinuation of dosing and 
if there are participants who develop ADAs, for those participants, SAEs must be collected up to 
3 months. 
The investigator must report any SAE that occurs after these time periods and that is believed to 
be related to study drug or protocol-specified procedure, (eg, a follow-up skin biopsy).
•
Medical occurrences that begin before the start of study treatment but after obtaining informed 
consent will be recorded on the appropriate section of the CRF module.
•
All SAEs will be recorded and reported to Sponsor or designee within 24 hours, as indicated 
in Appendix 3.

•
The investigator will submit any updated SAE data to the sponsor or designee within 24 hours
of updated information being available.
Investigators are not obligated to actively seek AEs or SAEs in former study participants. 
However, if the investigator learns of any SAE, including a death, at any time after a participant 
has been discharged from the study, and he/she considers the event reasonably related to the study 
treatment or study participation, the investigator must promptly notify the sponsor.
The method of evaluating and assessing causality of AEs and SAEs and the procedures for 
completing and reporting/transmitting SAE reports are provided in Appendix 3.
9.2.2
Method of Detecting AEs and SAEs
AEs can be spontaneously reported or elicited during open-ended questioning, examination, or 
evaluation of a participant. Care should be taken not to introduce bias when collecting AE and/or 
SAEs. Inquiry about specific AEs should be guided by clinical judgement in the context of known
AEs, when appropriate for the program or protocol.
9.2.3
Follow-up of AEs and SAEs
•
Nonserious AEs should be followed to resolution or stabilization, or reported as SAEs if they 
become serious (see Appendix 3).
•
Follow-up is also required for nonserious AEs that cause interruption or discontinuation of 
study treatment 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.
All SAEs will be followed until resolution, until the condition stabilizes, until the event is 
otherwise explained, or until the participant is lost to follow-up (as defined in Section 8.3).
Further information on follow-up procedures is given in Appendix 3.
9.2.4
Regulatory Reporting Requirements for SAEs
•
Prompt notification by the investigator to the Sponsor of SAEs is essential so that legal 
obligations and ethical responsibilities towards the safety of participants and the safety of a 
product under clinical investigation are met.
•
An investigator who receives an investigator safety report describing SAEs or other specific 
safety information (eg, summary or listing of SAEs) from the Sponsor will file it along with 
the IB and will notify the IRB/Independent Ethics Committee (IEC), if appropriate according 
to local requirements.
Sponsor or designee will be reporting AEs to regulatory authorities and ethics committees 
according to local applicable laws including European Directive 2001/20/EC and FDA Code of 
Federal Regulations 21 CFR Parts 312 and 320. A SUSAR (Suspected, Unexpected Serious

Adverse Reaction) is a subset of SAEs and will be reported to the appropriate regulatory authorities 
and investigators following local and global guidelines and requirements.
9.2.5
Pregnancy
If, following initiation of the study treatment, it is subsequently discovered that a participant is 
pregnant or may have been pregnant at the time of study exposure, including during at least for
6 days after study product administration, the investigator must immediately notify the BMS 
Medical Monitor/designee of this event and complete and forward a Pregnancy Surveillance Form 
to BMS Designee within 24 hours of awareness of the event and in accordance with SAE reporting 
procedures described in Appendix 3.
If the investigator determines a possible favorable benefit/risk ratio that warrants continuation of
study treatment, or re-initiation of study treatment, a discussion between the investigator and the 
BMS Medical Monitor/designee must occur. 
Protocol-required procedures for study discontinuation and follow-up must be performed on the 
participant.
Follow-up information regarding the course of the pregnancy, including perinatal and neonatal 
outcome and, where applicable, offspring information must be reported on the Pregnancy 
Surveillance Form.
Any pregnancy that occurs in a female partner of a male study participant should be reported to 
Sponsor or designee. In order for Sponsor or designee to collect any pregnancy surveillance 
information from the female partner, the female partner must sign an ICF for disclosure of this 
information. Information on this pregnancy will be collected on the Pregnancy Surveillance Form.
If any sexual activity (eg, vaginal, anal, oral) has occurred between a male participant and a 
pregnant partner(s) without the use of a condom during and at least for, 6 days after study product 
administration, the information should be reported to the Sponsor or designee, even if the male 
participant has undergone a successful vasectomy.
In order for Sponsor or designee to collect any pregnancy surveillance information from the female 
partner, the female partner(s) must sign an ICF for disclosure of this information. Information on 
the pregnancy will be collected on the Pregnancy Surveillance Form.
9.2.6
Laboratory Test Result Abnormalities
The following laboratory test result abnormalities should be captured on the nonserious AE CRF 
page or SAE Report Form electronic, as appropriate. Paper forms are only intended as a back-up 
option when the electronic system is not functioning.
•
Any laboratory test result that is clinically significant or meets the definition of an SAE 
•
Any laboratory test result abnormality that required the participant to have study treatment
discontinued or reduced.
•
Any laboratory test result abnormality that required the participant 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).
9.2.7
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 9.2 and Appendix 3 for reporting 
details).
Potential drug induced liver injury is defined as: 
1) AT (ALT or AST) elevation > 3 × 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.
9.2.8
Other Safety Considerations
Any significant worsening noted during interim or final physical examinations, ECGs, x-ray 
filming, any other potential safety assessment required or not required by protocol should also be 
recorded as a nonserious or serious AE, as appropriate, and reported accordingly.
9.3
Overdose
For this study, any dose of BMS-986259 greater than the designated dose described in Section 7
will be considered an overdose. All occurrences of intentional overdose must be reported as an 
SAE (see Section 9.2).
In the event of an overdose, the investigator should:
1) Contact the Medical Monitor immediately
2) Closely monitor the participant for AEs/SAEs and laboratory abnormalities until BMS-986259 
can no longer be detected systemically 
3) Obtain a serum sample for PK analysis if requested by the Medical Monitor (determined on a 
case-by-case basis)
4) Document the quantity of the excess dose as well as the duration of the overdosing in the CRF.
Decisions regarding dose interruptions or modifications will be made by the investigator in 
consultation with the Medical Monitor based on the clinical evaluation of the participant.

Safety
Planned time points for all safety assessments are listed in the Schedule of Activities (Section 2).
9.4.1
Physical Examinations
Refer to Schedule of Activities (Section 2).
The individual performing the physical examinations must be licensed by state law (or applicable 
local law) to perform a physical examination.
Documentation of who performed the examination is to be recorded in source notes. A targeted
physical examination may note any changes in the participant’s condition (body systems) since 
the last assessment and does not preclude examination of any of the other body systems as 
clinically indicated (ie, skin). Every effort should be made to ensure the same evaluator will 
complete the examination for each participant at all visits throughout the study.
9.4.2
Vital signs
Refer to Schedule of Activities (Section 2).
9.4.3
Electrocardiograms
Planned time points for ECGs are listed in the Schedule of Activities (Section 2). Single standard 
12-lead ECGs will be recorded after the participant has been resting for at least 5 minutes in the 
supine position.
The Investigator should review and assess all ECGs for any clinically significant abnormalities,
and initial and date the report.
The site should follow their standard practices for performing ECGs. Below is guidance to be used 
as a reference, if needed:
In preparation for the ECG, ensure there is minimal interference between the skin surface and the
electrode. Use alcohol to prepare the skin at each electrode site. Thick chest hair should be shaved 
to ensure sufficient contact.
Before attaching electrodes to pick-up points, spread the electrode with electrode gel. Place the
electrodes on bony areas, avoiding large muscle masses, to achieve better tracings as described
below. The participant must be supine and should refrain from movement during the ECG 
recording.
Ensure that the participant and the electrodes (including the neutral electrode) are not exposed to
conducting objects, even if grounded.

STATISTICAL CONSIDERATIONS
10.1
Sample Size Determination 
The primary objective of the study is to evaluate safety and tolerability of BMS-986259. It is 
estimated there may be ~10% to 20% early treatment withdrawal. Approximately 72 participants
will be randomized with 1:1 ratio to BMS-986259 subcutaneous QD and Placebo to have at least 
60 completers by the end of the study. An estimation approach will be used for comparison 
between BMS-986259 and placebo for hypotension rate. Point estimates and associated 95% 
confidence intervals for event rate and relative risk ratio will be constructed to provide plausible 
range of values for the true comparison of interest.

The investigator, Sponsor or designee should provide the IRB/IEC with reports, updates and other 
information (eg, expedited safety reports, amendments, and administrative letters) according to 
regulatory requirements or institution procedures.
COMPLIANCE WITH THE PROTOCOL AND PROTOCOL REVISIONS
The investigator should not implement any deviation or change to the protocol without prior 
review and documented approval/favorable opinion of an amendment from the IRB/IEC (and if 
applicable, also by local health authority) except where necessary to eliminate an immediate 
hazard(s) to study subjects/participants. 
If a deviation or change to a protocol is implemented to eliminate an immediate hazard(s) prior to 
obtaining relevant approval/favorable opinion(s) the deviation or change will be submitted, as soon 
as possible to:
•
IRB/IEC
•
Regulatory Authority(ies), if applicable by local regulations (per national requirements)
Documentation of approval/favorable opinion signed by the chairperson or designee of the 
IRB(s)/IEC(s) and if applicable, also by local health authority must be sent to BMS.
If an amendment substantially alters the study design or increases the potential risk to the 
participant: (1) the consent form must be revised and submitted to the IRB(s)/IEC(s) for review 
and approval/favorable opinion; (2) the revised form must be used to obtain consent from 
subjects/participants currently enrolled in the study if they are affected by the amendment; and (3) 
the new form must be used to obtain consent from new subjects/participants prior to enrollment.
If the revision is done via an administrative letter, investigators must inform their IRB(s)/IEC(s).
FINANCIAL DISCLOSURE
Investigators and sub-Investigators will provide the Sponsor with sufficient, accurate financial 
information in accordance with local regulations to allow the Sponsor to submit complete and 
accurate financial certification or disclosure statements to the appropriate health authorities.

Sponsor or designee will provide the investigator with an appropriate (ie, Global or Local) sample
informed consent form which will include all elements required by ICH, GCP and applicable
regulatory requirements. The sample informed consent form will adhere to the ethical principles 
that have their origin in the Declaration of Helsinki.
Investigators must:
•
Provide a copy of the consent form and written information about the study in the language in 
which the participant is most proficient prior to clinical study participation. The language must 
be non-technical and easily understood. 
•
Allow time necessary for participant or participant's legally acceptable representative to 
inquire about the details of the study.
•
Obtain an informed consent signed and personally dated by the participant or the participant's 
legally acceptable representative and by the person who conducted the informed consent 
discussion. 
•
Obtain the IRB/IEC’s written approval/favorable opinion of the written informed consent form 
and any other information to be provided to the subjects/participants, prior to the beginning of 
the study, and after any revisions are completed for new information.
If informed consent is initially given by a participant’s legally acceptable representative or legal 
guardian, and the participant subsequently becomes capable of making and communicating his or 
her informed consent during the study, consent must additionally be obtained from the participant.
Revise the informed consent whenever important new information becomes available that is 
relevant to the participant's consent. The investigator, or a person designated by the investigator,
should fully inform the participant or the participant's legally acceptable representative or legal 
guardian, of all pertinent aspects of the study and of any new information relevant to the 
participant's willingness to continue participation in the study. This communication should be 
documented. 
The confidentiality of records that could identify subjects/participants must be protected, 
respecting the privacy and confidentiality rules applicable to regulatory requirements, the 
subjects’/participants’ signed ICF and, in the US, the subjects’/participants’ signed HIPAA 
Authorization.
The consent form must also include a statement that BMS and regulatory authorities have direct 
access to participant records. 
The rights, safety, and well-being of the study subjects/participants are the most important 
considerations and should prevail over interests of science and society.

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 Sponsor or designee electronic data capture tool, electronic CRFs will be 
prepared for all data collection fields except for fields specific to SAEs and pregnancy, which will 
be reported on the electronic SAE form and Pregnancy Surveillance form, respectively. If 
electronic SAE form is not available, a paper SAE form can be used. 
The confidentiality of records that could identify subjects/participants must be protected, 
respecting the privacy and confidentiality rules in accordance with the applicable regulatory 
requirement(s).
The investigator will maintain a signature sheet to document signatures and initials of all persons 
authorized to make entries and/or corrections on CRFs. 
The completed CRF, SAE/pregnancy CRFs, must be promptly reviewed, signed, and dated by the 
investigator or qualified physician who is a subinvestigator and who is delegated this task on the 
Delegation of Authority Form. Subinvestigators in Japan may not be delegated the CRF approval 
task The investigator must retain a copy of the CRFs including records of the changes and 
corrections.
Each individual electronically signing electronic CRFs must meet Sponsor or designee training 
requirements and must only access the BMS electronic data capture tool using the unique user 
account provided by Sponsor or designee. User accounts are not to be shared or reassigned to other 
individuals
MONITORING
Sponsor or designee representatives will review data centrally to identify potential issues to 
determine a schedule of on-site visits for targeted review of study records. 
Representatives of BMS must be allowed to visit all study site locations periodically to assess the 
data quality and study integrity. On site they will review study records and directly compare them 
with source documents, discuss the conduct of the study with the investigator, and verify that the 
facilities remain acceptable.

Authorship of publications at BMS is aligned with the criteria of the International Committee of 
Medical Journal Editors (ICMJE, www.icmje.org). Authorship selection is based upon significant 
contributions to the study (ie, ICMJE criterion #1). Authors must meet all 4 ICMJE criteria for 
authorship:
1) Substantial intellectual contribution to the conception or design of the work; or the acquisition 
of data (ie, evaluable subjects with quality data), analysis, or interpretation of data for the work 
(eg, problem solving, advice, evaluation, insights and conclusion); AND
2) Drafting the work or revising it critically for important intellectual content; AND
3) Final approval of the version to be published; AND
4) Agreement to be accountable for all aspects of the work in ensuring that questions related to 
the accuracy or integrity of any part of the work are appropriately investigated and resolved.
Those who make the most significant contributions, as defined above, will be considered by BMS 
for authorship of the primary publication. Sub-investigators will generally not be considered for 
authorship in the primary publication. Geographic representation will also be considered.  
Authors will be listed by order of significant contributions (highest to lowest), with the exception 
of the last author. Authors in first and last position have provided the most significant contributions 
to the work. 
For secondary analyses and related publications, author list and author order may vary from 
primary to reflect additional contributions.

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

SERIOUS ADVERSE EVENTS
Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any 
dose:
Results in death
Is life-threatening (defined as an event in which the participant was at risk of death at the time 
of the event; it does not refer to an event which hypothetically might have caused death if it were 
more severe)
Requires inpatient hospitalization or causes prolongation of existing hospitalization (see NOTE 
below)
NOTE:
The following hospitalizations are not considered SAEs in BMS clinical studies: 
•
a visit to the emergency room or other hospital department < 24 hours, that does not result 
in admission (unless considered an important medical or life-threatening event)
•
elective surgery, planned prior to signing consent
•
admissions as per protocol for a planned medical/surgical procedure
•
routine health assessment requiring admission for baseline/trending of health status (e.g., 
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 (e.g., lack of housing, economic inadequacy, 
caregiver respite, family circumstances, administrative reason)
•
admission for administration of anticancer therapy in the absence of any other SAEs (applies 
to oncology protocols)
Results in persistent or significant disability/incapacity
Is a congenital anomaly/birth defect
Is an important medical event (defined as a medical event(s) that may not be immediately life-
threatening or result in death or hospitalization but, based upon appropriate medical and 
scientific judgment, may jeopardize the participant or may require intervention [e.g., medical, 
surgical] to prevent one of the other serious outcomes listed in the definition above.) Examples 
of such events include, but are not limited to, intensive treatment in an emergency room or at 
home for allergic bronchospasm; blood dyscrasias or convulsions that do not result in 
hospitalization.) Potential drug induced liver injury (DILI) is also considered an important 
medical event. (See Section 9.2.7 for the definition of potential DILI.) 
Pregnancy and potential drug induced liver injury (DILI) must follow the same transmission timing 
and processes to BMS as used for SAEs (see section 9.2.5 for reporting pregnancies).

Any component of a study endpoint that is considered related to study therapy should be reported 
as SAE (e.g., death is an endpoint, if death occurred due to anaphylaxis, anaphylaxis must be 
reported).
EVALUATING AES AND SAES
Assessment of Intensity
The intensity of AEs is determined by a physician and will use the following levels:
•
Mild: An event that is easily tolerated by the subject, causing minimal discomfort, and not 
interfering with everyday activities.
•
Moderate: An event that causes sufficient discomfort and interferes with normal everyday 
activities.
•
Severe: An event that prevents normal everyday activities. An AE that is assessed as severe 
should not be confused with an SAE. Severe is a category utilized for rating the intensity of 
an event; and both AEs and SAEs can be assessed as severe.
Assessment of Causality
•
The investigator is obligated to assess the relationship between study intervention and each 
occurrence of each AE/SAE.
•
A “reasonable possibility” of a relationship conveys that there are facts, evidence, and/or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled out.
•
The investigator will use clinical judgment to determine the relationship.
•
Alternative causes, such as underlying disease(s), concomitant therapy, and other risk 
factors, as well as the temporal relationship of the event to study intervention administration 
will be considered and investigated.
•
The investigator will also consult the Investigator’s Brochure (IB) and/or Product 
Information, for marketed products, in his/her assessment.
•
For each AE/SAE, the investigator must document in the medical notes that he/she has 
reviewed the AE/SAE and has provided an assessment of causality.
•
There may be situations in which an SAE has occurred and the investigator has minimal 
information to include in the initial report to Sponsor. However, it is very important that the 
investigator always make an assessment of causality for every event before the initial 
transmission of the SAE data to Sponsor.
•
The investigator may change his/her opinion of causality in light of follow-up information 
and send a SAE follow-up report with the updated causality assessment.
•
The causality assessment is one of the criteria used when determining regulatory reporting 
requirements.
Follow-up of AEs and SAEs
If only limited information is initially available, follow-up reports are required. (Note: Follow-
up SAE reports must include the same investigator term(s) initially reported.)

If an ongoing SAE changes in its intensity or relationship to study treatment or if new 
information becomes available, the SAE report must be updated and submitted within 24 hours 
to BMS (or designee) using the same procedure used for transmitting the initial SAE report.
All SAEs must be followed to resolution or stabilization.
REPORTING OF SAES TO SPONSOR OR DESIGNEE
•
SAEs, whether related or not related to study treatment, and pregnancies must be reported 
to BMS (or designee) immediately within 24 hours of awareness of the event.
•
SAEs must be recorded on the SAE Report Form.
−
The required method for SAE data reporting is through the eCRF.
−
The paper SAE Report Form is only intended as a back-up option when the electronic 
data capture (EDC) system is unavailable/not functioning for transmission of the eCRF 
to BMS (or designee).
♦In this case, the paper form is transmitted via email or confirmed facsimile (fax) 
transmission
♦When paper forms are used, the original paper forms are to remain on site
•
Pregnancies must be recorded on a paper Pregnancy Surveillance Form and transmitted via 
email or confirmed facsimile (fax) transmission

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

human teratogenicity or fetotoxicity. This should be evaluated in context of safety margins 
from the no-observed adverse effect level (NOAEL) or the time required for 5 half-lives of the 
IMP to pass.
METHODS OF CONTRACEPTION
Local laws and regulations may require use of alternative and/or additional contraception methods.
Highly Effective Contraceptive Methods That Are User Dependent
Failure rate of <1% per year when used consistently and correctly.a
•
Combined (estrogen- and progestogen-containing) hormonal contraception associated with 
inhibition of ovulation and/or implantation (This method of contraception can only be used 
by WOCBP participants in studies where hormonal contraception is permitted by the study 
protocol)b 
−
oral (birth control pills)
−
intravaginal (vaginal birth control suppositories, rings, creams, gels)
−
transdermal 
•
Combined (estrogen-and progestogen-containing) hormonal contraception must begin at 
least 30 days prior to initiation of study therapy
•
Progestogen-only hormonal contraception associated with inhibition of ovulation (This
method of contraception can only be used by WOCBP participants in studies where 
hormonal contraception is permitted by the study protocol)b 
−
oral 
−
injectable 
•

ovulation and/or implantation (This method of contraception can only be used by WOCBP 
participants in studies where hormonal contraception is permitted by the study protocol)b
•
Intrauterine device (IUD)
•
Intrauterine hormone-releasing system (IUS) (This method of contraception can only be 
used by WOCBP participants in studies where hormonal contraception is permitted by the 
study protocol) b,c
•
Bilateral tubal occlusion
•
Vasectomized partner 
Male participants will be required to always use a latex or other synthetic condom during any sexual 
activity (eg, vaginal, anal, oral) with WOCBP; even if the participants have undergone a successful 
vasectomy or if their partner is already pregnant or breastfeeding.

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

NEW YORK HEART ASSOCIATION FUNCTIONAL 
CLASSIFICATION
Heart failure is usually classified according to the severity of the patient’s symptoms. The table
below describes the most commonly used classification system, the New York Heart Association 
(NYHA) functional classification. It places patients in 1 of 4 categories based on how much they 
are limited during physical activity.
Class
Patient Symptoms
I
No limitation of physical activity. Ordinary physical activity does not cause 
undue fatigue, palpitation, or dyspnea (shortness of breath).
II
Slight limitation of physical activity. Comfortable at rest. Ordinary physical 
activity results in fatigue, palpitation, or dyspnea (shortness of breath).
III
Marked limitation of physical activity. Comfortable at rest. Less than 
ordinary activity causes fatigue, palpitation, or dyspnea.
IV
Unable to carry on any physical activity without discomfort. Symptoms of 
heart failure at rest. If any physical activity is undertaken, discomfort 
increases.
Class
Objective Assessment
A
No objective evidence of cardiovascular disease. No symptoms and no 
limitation in ordinary physical activity.
B
Objective evidence of minimal cardiovascular disease. Mild symptoms and 
slight limitation during ordinary activity. Comfortable at rest.
C
Objective evidence of moderately severe cardiovascular disease. Marked 
limitation in activity due to symptoms, even during less-than-ordinary 
activity. Comfortable only at rest.
D
Objective evidence of severe cardiovascular disease. Severe limitations. 
Experiences symptoms even while at rest.
