being placed on the liver transplant wait list  
2. Not eligible for liver transplant (limited to 25 patients) 
 
Methodology:  
Prospective Terlipressin Group - Patients to be treated with open label terlipressin by 
infusion following an initial bolus dose of 0.5mg. 
Retrospective Control Group – Historical patients who would have met 
inclusion/exclusion criteria detailed below and received at least 48 hours of treatment for 
HRS-AKI according to center’s standard-of-care (Midodrine/Octreotide (M&O), 
albumin, or other vasopressor) 
Number of Subjects (Planned):   
Prospective Terlipressin Group - approximately 50 terlipressin treated subjects 
Retrospective Control Group - approximately 15-25 subjects per clinical site that were 
treated for HRS-AKI, that would have met the inclusion/exclusion criteria below as well 
as having critical clinical data points to enable a comparison of the Prospective and 
Retrospective groups. Retrospective cases collected from each site should include 
eligible patients starting from prior to site IRB approval for this protocol and going back

Terlipressin will be administered intravenously as a bolus injection for the first dose, 
then by continuous IV infusion.   
 
Retrospective Control Group: 
Dose and method of administration for M&O, albumin, or other vasopressor 
 
Dosage and Mode of Administration: 
 
For Retrospective Control Group: 
Dosing for M&O , albumin, or other vasopressor will be reported as it was recorded 
on the subject’s chart. 
 
For Prospective Terlipressin Group: 
 
Terlipressin will be supplied in single-use, sterile 6-mL vials containing 1 mg of 
lyophilized Terlipressin acetate (equivalent to 0.85 mg Terlipressin free base) with 10 
mg mannitol as a bulking agent/stabilizer. 
 
Initial Dosing: 
2 
Terlipressin will be administered intravenously as a bolus injection (the vial will be 
reconstituted with 5 mL of sterile 0.9% sodium chloride solution and given over 
1 minute at a dose of 0.5 mg.   
• Continued dosing will be by 2 mg infusion per day.  For continuous infusion, the 
dose of terlipressin is to be dissolved in 0.9% sodium chloride solution and 
infused with a pump. 
 
Dose Modifications: 
- 
If on Day 3 the SCr is not 30% lower from the baseline value, increase infusion 
dose to 4 mg per day.  
 
- 
If on Day 5 the SCr is not 50% lower from the baseline value, increase infusion 
dose to 6-8 mg per day, per PI discretion. Dosing can be increased by more than 
1 mg increment at Day 5 or beyond, up to a maximum of 8 mg/day. 
 
• If the subject has infusion stopped for ≥ 4 hours, a 0.5 mg bolus should be given 
prior to restarting infusion.  
• The drug should not be used in subjects with severe coronary artery disease or in 
the setting of circulatory overload, pulmonary edema, or bronchospasm as 
determined by the Investigator. If drug therapy has been initiated, Investigator 
can also decide not to increase the dose, based on the patient’s status with regard 
to the above, based on individual subject condition.

• If dosing is interrupted due to an adverse event, terlipressin may be re-started, at 
the discretion of the investigator, at the same or lower dose as per protocol. 
Terlipressin will not be restarted if dosing was interrupted due to cardiac 
ischemia or mesenteric ischemia. 
 
Treatment Discontinuation: 
• Terlipressin may be continued until 24 hours after serum creatinine has reached 
the lowest value possible as determined by Principal Investigator, up to a 
maximum of 14 days.  
• After a minimum of 72 hours post final dose escalation and tolerability, if the SCr 
is at or above enrollment value, terlipressin should be discontinued.  
• If 72 hours after final dose escalation, there is no further improvement in SCr, 
continuation of terlipressin is at the discretion of the Principal Investigator at the 
clinical site. 
• If a subject is initiated on RRT, terlipressin can be continued for a maximum of 72 
hours after initiation of RRT. 
• Terlipressin must be discontinued when the subject is to undergo liver 
transplantation, TIPS, or any other vasopressor therapy (single administration of 
vasopressor for cardiac stress test is acceptable) 
• Dosing must be permanently discontinued if an event of cardiac ischemia or 
mesenteric ischemia occurs. 
 
Retreatment: 
If judged by the investigator to be potentially beneficial, subjects who demonstrate at 
least a partial response during the initial treatment course (at least 50% reduction in 
SCr) and develop recurrence of HRS-AKI may be retreated for a maximum of 
14 days. To qualify for retreatment the subject must again meet the study 
inclusion/exclusion criteria. Retreatment may occur within 90 days of the subject’s 
first dose of terlipressin. 
Duration of Treatment: 
For the Prospective Terlipressin Group, the active treatment period will be up to 14 days, 
allowing 1 retreatment cycle.  
For both Prospective and Retrospective Subjects: 
All subjects will be followed: 
Post treatment clinical data collection will be through phone call and chart review.  
Creatinine, BUN and eGFR will be recorded per standard of care, recording mortality 
and the date of last dialysis (CVVH or HD) session for the following time points:

3 Introduction 
3.1 Hepatorenal Syndrome 
Hepatorenal syndrome (HRS) Type 1, a potentially reversible renal failure, is a serious, rapidly 
progressing, fatal orphan disease complicating decompensated chronic liver disease associated 
with cirrhosis (Arroyo, 1996; Salerno, 2007; Angeli, 2015). The estimated United States (US) 
annual incidence for HRS Type 1 ranges between 9,000 and 20,000 patients (Marrero, 2003; 
Muir, 2002; Murkerjee, 2002; National Hospital Discharge Survey 2005), establishing it as an 
orphan disease. The death rate from chronic liver disease and cirrhosis has been rising, while the 
death rates for other major diseases such as stroke, cancer, heart disease, and diabetes have gone 
down in the past 15 years (Centers for Disease Control and Prevention 2013; Ma, 2015). 
As indicated in the American Association for the Study of Liver Diseases (AASLD) Guidelines, 
at present, there is no available pharmacological therapy (i.e., approved or proven) in the US or 
Canada for HRS Type 1 (Runyon, 2013) and there remains a significant unmet need.  
An increasing body of knowledge of the pathophysiology of HRS Type 1 has demonstrated that 
vasoconstrictive drug therapy may improve renal function in HRS Type 1 (Salerno, 2007; 
European Association for the Study of the Liver 2010). Terlipressin has been extensively studied 
as a splanchnic vasoconstrictor for the treatment of HRS Type 1 and is the standard of care for 
this condition wherever the drug is available (European Association for the Study of the Liver 
2010). Although there has been some off-label use of other vasoconstrictors, a recent study has 
shown that the most commonly used agents (i.e., combination of midodrine and octreotide) are 
not effective (Cavallin, 2015). 
There is a shift in HRS terminology to move away from HRS Type 1 and HRS Type 2 to the new 
designations of HRS-Acute Kidney Injury (HRS-AKI) and HRS-Chronic Kidney Disease (HRS-
CKD), respectively, in order to better harmonize with the existing nomenclature in nephrology, 
the clinical consequences of kidney injury, and initiation of treatment at earlier time points when 
it is more effective (Angeli, 2015). HRS-AKI removes the condition of creatinine doubling over 
two weeks, as often patients with ascites, a precipitating event, and HRS physiology may not 
have had a creatinine checked in the preceding two weeks but would still benefit from HRS 
treatment.  Additionally, HRS-AKI divides the kidney injury into stages (1-3) to mirror the AKI 
criteria set forth by the Acute Kidney Injury Network (AKIN) (Angeli, 2015).

3.2 Terlipressin  
Terlipressin is a synthetic vasopressin analogue that acts as a systemic vasoconstrictor via the 
vascular vasopressin V1 receptors. In HRS patients the strong V1 receptor-mediated 
vasoconstrictor activity of terlipressin, particularly in the splanchnic area, increases effective 
intravascular volume and mean arterial pressure (MAP), ameliorates renin-angiotensin-
aldosterone system and sympathetic nervous system hyperactivity, and improves renal blood 
flow. These corrective hemodynamic effects culminate in improved renal function, thereby 
providing the pharmacologic rationale for treatment of HRS with terlipressin (Arroyo, 2000; 
Ginès, 2003; Kiszka-Kanowitz, 2004). 
After intravenous (IV) administration of terlipressin, the glycyl residues of terlipressin are 
cleaved by endogenous tissue proteases. Thus, terlipressin levels in the blood decrease rather 
rapidly and the pharmacologically active metabolite lysine-vasopressin is released gradually 
from tissues into the circulation.  Intravenous terlipressin can be delivered quickly via bolus 
injection or slowly through continuous infusion.  There is evidence that continuous infusion 
leads to fewer adverse events and lower total terlipressin doses to achieve HRS reversal 
(Cavallin, 2016).  A bolus injection prior to continuous infusion will achieve therapeutic levels 
earlier than continuous infusion alone. 
Terlipressin is approved in many countries and regions outside the US where it has been a 
standard of care for decades in the treatment of subjects with liver cirrhosis and esophageal 
variceal hemorrhage (EVH) (de Franchis, 2005; Ioannou, 2003), and has more recently become a 
standard of care for the treatment of subjects with HRS Type 1 where it is available 
(EASL, 2010). Terlipressin has been approved for the treatment of HRS Type 1 in Australia, 
France, Ireland, South Korea, Mexico, Taiwan, Spain, India, Brazil, Turkey, and Portugal.  
3.3 Efficacy  
Improvement in renal function is the goal of therapy for HRS-AKI; improvement in renal 
function is associated with improvement in clinical outcomes and improved prognosis, with or 
without liver transplantation. HRS reversal is a widely accepted, clinically meaningful response 
to treatment for HRS Type 1, as apparent inexorable, rapid progression of renal failure is arrested 
and normal renal function in the setting of decompensated liver disease is restored. The primary 
endpoint of HRS reversal (1 serum creatinine [SCr] value of ≤ 1.5 mg/dL) is the standard 
endpoint utilized in the literature and HRS treatment guidelines (Arroyo, 1996; Salerno, 2007; 
Angeli, 2015).  Both terlipressin bolus and continuous infusion have been shown to be effective 

Collaborative Research Study, Version 4: 06/29/21

University of Pennsylvania 
Page 26 of 69 
Confidential and Proprietary 
in the treatment of HRS Type 1, with fewer adverse events occurring in the cohort receiving 
continuous infusion. (Cavallin, 2016). 
3.4 Safety  
The safety characteristics of terlipressin is captured in the literature and post-marketing data 
from the World Health Organization (WHO) database. In general, terlipressin has a well-
established safety profile in the treatment of patients with HRS Type 1. The safety risks are 
predictable and recognizable. The adverse drug reactions can be readily managed and reversed 
by terlipressin dose reduction or interruption in hospital-care settings.  Continuous infusion of 
terlipressin may be more tolerable than bolus injection (Cavallin, 2016). 
3.5 Retrospective Control Group:  M&O Treated Subjects 
3.5.1 Midodrine and Octreotide 
Midodrine is an oral alpha-receptor agonist that binds to peripheral alpha-receptors on both 
arterioles and veins, leading to an increase in blood pressure (Cruz, 2000).   Midodrine is a 
prodrug; it is transformed into the active metabolite de-glymidodrine, a compound similar in 
structure to norepinephrine (Cruz, 2000). Midodrine was approved for use in the United States 
for treatment of orthostatic hypotension in 1996. Octreotide is somatostain analogue that binds to 
somatostain receptors and mimics the physiologic effects of somatostatin including inhibition of 
various hormones, some of which lead to vasodilation, thus octreotide can cause arteriolar 
vasoconstriction leading to increases in blood pressure (Gold Standard).  Octreotide can be 
administered via intravenous or subcutaneous routes and was approved for use in the United 
States in 1988 for treatment of certain neuroendocrine tumors. 
3.5.2 M&O Off-Label Use 
The combination of midodrine/octreotide (M&O), in conjunction with albumin, has been used 
“off-label” in the United States for treatment of HRS Type 1 for years. Small studies, mostly 
single center, have demonstrated favorable outcomes for M&O in treatment of HRS Type 1 
(Angeli, 1999; Wong, 2004; Esrailian, 2007).  The use of M&O plus albumin is recommended in 
the 2012 AASLD guidelines for the treatment of HRS Type 1 (Runyon, 2013) , particularly in 
light of the fact that terlipressin was not available in the United States at the time of publication.  
However, the largest multi-centered study comparing terlipressin to M&O undertaken by the 
Italian Association for the Study of the Liver Study Group on Hepatorenal Syndrome, was 
stopped early due to the considerable differences in HRS reversal between terlipressin and M&O 
(55.5 vs 4.8%, p<0.001) (Cavallin, 2015).

Midodrine/Octreotide use in patients on the liver transplant wait list with HRS Type 1 
Increasing the duration of time in which a patient with decompensated cirrhosis experiences 
renal dysfunction decreases the likelihood of renal recovery after liver transplant (Campbell, 
2005). Wong et al retrospectively evaluated patients that had experienced HRS Type 1 without 
reversal prior to liver transplant at University of Toronto between 2001 to 2010 (n=62); M&O 
was used as treatment of HRS Type 1 in the majority of these patients (Wong, 2015).  While 
none of the patients in the cohort had HRS reversal, 76% were free from dialysis 30 days after 
liver transplant and had a serum creatinine ≤ 1.5 mg/dL (Wong, 2015).  The duration of HRS 
type 1 and the number of dialysis days prior to liver transplant were highly predictive of post-
transplant renal function (Wong, 2015).  Additionally, those patients that were not dialysis-free 
30 days post-transplant with serum creatinine ≤ 1.5 mg/dL had higher mortality rates (Wong, 
2015).  This data suggests that even if HRS reversal is not possible, that limiting the dialysis 
days and length of HRS type 1 can lead improve renal outcomes post-transplant. 
4 Study Rationale 
The purpose of this open labeled study is to assess safety/efficacy for continuous terlipressin 
infusion in liver transplant-eligible adult subjects with Hepatorenal syndrome- Acute Kidney 
Injury (HRS-AKI).

This is a collaborative open-label, multicenter study of terlipressin infusion following an initial 
bolus dose of 0.5mg. Written informed consent will be obtained by the investigator, sub-
investigator, or qualified designee from the subject or legally authorized representative (LAR) 
prior to the subject enrollment into the study. Approximately 50 subjects are planned to be 
enrolled at 5-10 sites in the US. Subjects will receive up to 14 days of terlipressin treatment. 
Retrospective Control Group 
This study will also seek clinical data from a Retrospective Control Group of patients who would 
have met inclusion/exclusion criteria detailed below and received at least 48 hours of treatment 
with Midodrine and Octreotide (M&O), albumin, or other vasopressor used for the treatment of 
HRS-AKI.  Retrospective cases collected from each site should include eligible patients starting 
from prior to site IRB approval for this protocol and going back to January 2015.  Subjects 
enrolled in a blinded clinical trial in this time period are excluded.

deviates from the protocol, based on the judgment of the investigator (or a responsible, 
appropriately trained professional designated by the investigator). In the event of a significant 
deviation from the protocol due to an emergency, accident, or error, the investigator or designee 
must contact the sponsor, or their agent, at the earliest possible time by telephone. This will 
allow an early joint decision regarding the subject’s continuation in the study. The investigator 
and the sponsor will document this decision. The Institutional Review Board (IRB) will be 
informed of all protocol deviations by the investigator in accordance with the IRB established 
procedure. No deviations from the protocol of any type will be made without complying with all 
the IRB established procedures. Significant deviations from the protocol may not allow that 
patient’s clinical data to be included in the Intent-To-Treat Analysis. 
8 Terlipressin  
Terlipressin will be supplied in single-use, sterile 6-mL vials containing 1 mg of lyophilized 
terlipressin acetate (equivalent to 0.85 mg terlipressin free base) with 10 mg mannitol as a 
bulking agent/stabilizer.

The active ingredient, N-[N-(N-glycylglycyl) glycyl]-8-L-lysinevasopressin, is a synthetically 
manufactured hormonogen of 8-lysine vasopressin, composed of 12 amino acids and having the 
characteristic ring structure of a cyclic nonapeptide with a disulfide bridge between the 4th and 
the 9th amino acid. Three glycyl-amino acids are substituted at position 1 (cysteine) of 
8-lysine-vasopressin. By this N-terminal extension of 8-lysine-vasopressin the metabolic 
degradation rate of the active ingredient is significantly reduced, because the glycyl molecules 
inhibit rapid N-terminal enzymatic degradation. 
 
8.1 Packaging and Labeling 
Single-use, sterile 6-mL vials of a lyophilized solid containing 1 mg of terlipressin acetate 
(equivalent to 0.85 mg terlipressin free base) will be provided to the sites. Study drug labels will 
comply with local regulatory requirements, including sponsor name and address, protocol 
number, storage conditions and US Investigational New Drug (IND) caution statement. 
8.2 Study Drug Storage and Preparation 
Study drug should be stored in a secure location at 2ºC to 8ºC until reconstituted.  Reconstituted 
study drug bolus and study drug infusion bags may be stored up to 48 hours at refrigerated 
storage conditions (2ºC to 8ºC) and at room temperature (25 ºC) for 24 hours. (Appendices A and 
C). 
Terlipressin is stable at 2ºC to 8ºC up to 48 hours in 0.9% sodium chloride solution at a 
concentration of 1mg Terlipressin in 5mL solution (Appendix A). 
Microbiology studies at a concentration of 2 mg Terlipressin in 50 mL of 0.9% sodium chloride 
solution are included in Appendix C.  Stability at a concentration of 0.034 mg/mL has been 
previously demonstrated (Bui 2020). Study drug assignment, preparation, and dosing will be 
strictly limited to the investigators and their designees.  Study doses will be labelled to ensure 
drug is used only for authorized investigational use only.  The subject’s initials will be placed on 
the label by the Pharmacists at the time of dispensing.

Confidential and Proprietary 
For the first dose of terlipressin, each vial will be reconstituted with 5 mL of sterile 0.9% sodium 
chloride solution and administered intravenously as a bolus injection and given over 1 minute at 
a dose of 0.5 mg.   
For continuous infusion, the dose of terlipressin is to be dissolved in 0.9% sodium chloride 
solution and infused with a pump (Appendix B).  
8.4 Administration 
Subjects in the Prospective Terlipressin Group: 
Single-use, sterile 6-mL vials containing 1 mg of lyophilized terlipressin acetate (equivalent to 
0.85 mg terlipressin free base) with 10 mg mannitol as a bulking agent/stabilizer.  
• For initial bolus dose of 0.5mg, the vial will be reconstituted with 5 mL of sterile 0.9% 
sodium chloride solution and given over 1-minute push.  
• Continued dosing will be by 2mg infusion per day for Days 1, and 2.  For continuous 
infusion, the dose of terlipressin is to be dissolved in 0.9% sodium chloride solution and 
infused with a pump.   
• If on Day 3 the SCr is not 30% lower from the baseline value, increase infusion dose to 4 mg 
per day.  
• If on Day 5 the SCr is not 50% lower from the baseline value, increase infusion dose to 6-8 
mg per day, per PI discretion. Dosing can be increased by more than 1 mg increment at Day 5 
or beyond, up to a maximum of 8 mg/day. 
• If the subject has infusion stopped for ≥ 4 hours, a 0.5 mg bolus should be given prior to 
restarting infusion.  
• The drug should not be used in subjects with severe coronary artery disease or in the setting 
of circulatory overload, pulmonary edema, or bronchospasm as determined by the 
Investigator. If drug therapy has been initiated, Investigator can also decide not to increase 
the dose, based on the patient’s status with regard to the above, based on individual subject 
condition.

• If dosing is interrupted due to an adverse event, terlipressin may be re-started, at the 
discretion of the investigator, at the same or lower dose as per protocol. Terlipressin will not 
be restarted if dosing was interrupted due to cardiac ischemia or mesenteric ischemia. 
Subjects in the Retrospective Control Group: 
 
The dose and method of administration for Midodrine/Octreotide (M&O), albumin, or other 
vasopressor will be recorded as noted in the patient’s medical record.  To be included as a 
completed subject in this study, patients must have been treated for at least 48 hours with 
albumin infusions beyond volume resuscitation and diuretic withdrawal.  Vasopressors also need 
to be used for a minimum of 48 hours. 
8.5 Study Drug Accountability 
The investigator or designee must maintain an inventory record of study drug administered to 
assure the regulatory authorities and the sponsor that the investigational new drug will not be 
dispensed to any person who is not a subject under the terms and conditions set forth in this 
protocol. Neither the investigators nor any designees may provide study drug to any subject not 
formally enrolled in this protocol. 
The study drug supplied for use in this study is to be prescribed only by the investigator or 
properly assigned designee and may not be used for any purpose other than that outlined in this 
protocol. 
All unused investigational product will be handled per study drug supplier instructions at 
conclusion of the study. Periodic review of drug accountability records will be conducted by 
investigational site monitors. Final review and reconciliation of the accountability records will be 
performed by the sponsor or designee.

participation. The investigator or qualified designee will not be required to obtain sponsor 
approval to enroll subjects.  Enrollment of subjects determined not to qualify for the study during 
sponsor monitoring oversight may result in study site closure.  Written informed consent will be 
obtained by the investigator, sub-investigator, or qualified designee from the subject or legally 
authorized representative prior to the subject qualification form being completed. 
10.2 Pre-Treatment Period 
The pre-treatment period occurs prior to administration of study drug and includes performing 
baseline assessments and collection of prior medication information.  
The qualifying SCr value (SCr value at least 48 hours after both diuretic withdrawal and after the 
beginning of albumin fluid challenge) is considered the enrollment SCr and must be drawn prior 
to study drug administration. 
10.3 Active Study Period (14 Days) 
Dosing (Up to 14 Days) 
The active study period extends from the initiation of study treatment through Day 14 or 
discharge from the hospital for any reason, whichever occurs first. Study drug will be 
administered as described in Section 7.3.2.  Concomitant medications will be collected during 
this active study period.  See Table 8.1 for the schedule of assessments during the active study 
period.

o Descriptive analysis of number simultaneous liver kidney transplants and episodes of 
graft rejection at Day 90 and Day 365 after liver transplant 
 
14 Serious Adverse Events 
Only Serious Adverse Events will be collected for this study for the prospective group only.  
Safety review and assessments will be made only for the Prospective Terlipressin Group from 
time of first dose through 30 days after end of treatment. SAEs are collected from the start of 
study drug until 30 days after study drug was discontinued.  Non-serious Adverse Events are not 
required to be collected for this study.   
The investigator will record the nature, causality, severity, treatment, and outcome of the SAE, 
and will determine whether there is a “reasonable probability” that the study drug treatment 
caused the event. 
14.1 SAE Definitions 
The following definitions are based on: 
• International Conference on Harmonization (ICH) E2A: International Conference on 
Harmonisation Tripartite Guideline: Clinical Safety Data Management: Definitions and

• Code of Federal Regulations Title 21, Part 312.32 (2011).  
Also included are events that are common to this subject population. 
14.2 Suspected Unexpected Serious Adverse Reaction (SUSAR) 
This is an unexpected SAE or suspected unexpected adverse reaction (SUSAR) which is not 
listed in the Investigator’s Brochure (IB), nor listed at the specificity or severity observed. If an 
SUSAR is listed in the IB as occurring with a specific class of drugs, or occurring as part of a 
disease process, or from the pharmacological properties of the drug, but not specifically 
mentioned as occurring with the particular drug under investigation, it should be considered 
unexpected. 
14.3 Serious Adverse Event Definition 
Serious adverse events (SAE) are defined (in the view of the investigator or the sponsor) as any 
untoward medical occurrence that meets any of the following criteria: 
• Resulted in death. 
• Is life-threatening (if an AE or SUSAR places a subject 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 prolongation of existing hospitalization. 
• Results in disability (persistent or significant incapacity or substantial disruption of the 
ability to conduct normal life functions).  
• Is a congenital anomaly/birth defect.  
• Is an important medical event that may not result in death, be life-threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical 
judgment, they may jeopardize the subject and may require medical or surgical 
intervention to prevent one of the outcomes listed in this definition. Examples of an 
important medical event include allergic bronchospasm, blood dyscrasias, convulsions 
that do not result in inpatient hospitalization, or drug dependence/abuse.

14.4 Severity of an Adverse Event 
Intensity of an AE, assessed by the investigator and graded as mild, moderate, or severe, 
irrespective of the relationship to the drug or seriousness of the event, and evaluated according to 
the following scales: 
• Mild - awareness of the symptom but easily tolerated. 
• Moderate - discomfort enough to interfere with normal activities. 
• Severe - Incapacitating with the inability to perform normal activities. 
14.5 Study Drug Causality 
Study drug causality will be assessed as follows: 
Unrelated: An AE that is clearly and incontrovertibly due to extraneous causes (disease, 
environment, etc.) and does not meet the criteria for ‘possible’ or ‘probable.’ 
Possible: The connection between the AE and study treatment appears unlikely but cannot be 
ruled out with certainty. An AE may be considered ‘possibly related’ if it has at least 2 of the 
following: 
• It follows a reasonable temporal sequence from administration of study drug. 
• It may readily have been produced by the subject's clinical state or by environmental or 
toxic factors. 
• It follows a known response pattern to study drug. 
 
Probable: An AE that is considered to be related to study drug treatment with a high degree of 
certainty. An AE may be considered probably related if: 
• It follows a reasonable temporal sequence from administration of study drug.  
• It cannot be reasonably explained by the known characteristics of the subject's clinical 
state. 
• It follows a known pattern of response to study drug treatment. 
• It reappears upon rechallenge.

Overdose is defined as an accidental or intentional/infusion or excessive dose of a product. 
14.7 Collection of Adverse Events/Serious or Unexpected 
Any adverse event occurring prior to signing the ICF and prior to 1st dose of study drug should 
be considered medical history or a pre-existing condition and will be collected on the Medical 
History CRF.

SAEs will be assessed and recorded beginning with study drug administration until 30 days after 
discontinuation of study drug.  
14.8 Laboratory Abnormalities 
The investigator will review clinical laboratory test results in a timely fashion. Laboratory 
abnormalities deemed clinically significant and serious should be reported to the sponsor as 
appropriate. 
14.9 Hospitalizations 
Planned hospital admissions and/or planned surgical operations for an illness or disease, which 
existed before the subject was randomized are not to be considered SAEs (e.g., re-hospitalization 
for liver transplantation). However, a baseline condition which deteriorates during the clinical 
study may be considered an SAE.  
Following the initial hospital discharge, all re-hospitalizations within 30 days post end of 
treatment (except for planned hospital admissions or procedures as described above) are to be 
recorded as a SAE.  
14.10 Complications of the Disease 
Complications frequently associated with HRS - AKI are expected to occur, but should be 
recorded as a SAE, as applicable, e.g., EVH, hepatic encephalopathy, sepsis, pneumonia, urinary 
tract infection.  
Since HRS - AKI is the indication under investigation, worsening or aggravation of HRS - AKI 
during the active treatment period (including non-response) will NOT be recorded as a SAE 
unless HRS – AKI is the cause of death or results in a subsequent re-hospitalization due to 
suspected recurrence. 
14.11 Pregnancy  
Pregnancy occurring in a subject is NOT considered an SAE. However, the investigator must 
collect pregnancy information for subject and/or subject’s partner if the fetus was exposed to the 
study drug.

Investigators must report all SAEs to the sponsor (and applicable IRB) whether or not the events 
are study drug-related or expected.  
All SAEs must be reported on a SAE form and faxed/scanned to International HealthCare (IHC) 
within 24 hours of an investigator becoming aware of the event:  
IHC Safety Review Officer 
Email: infusealerts@ihcresearch.com   
 
The initial SAE form does not need to be signed by the investigator; however, a signed SAE 
form is required for final SAE reporting. The initial scan by the investigator will include 
(whenever possible) a detailed description of the event including start and stop dates, causality 
assessment by the investigator, and supported as needed with written copies of medical records, 
autopsy reports, and other appropriate documents. Follow-up information (including information 
requested by the sponsor) should be reported by fax/scan within 24 hours of availability. The 
investigator is expected to make every effort to collect follow up information for each SAE in a 
timely fashion after the initial reporting of the SAE. 
If there are any specific questions regarding a SAE classification, the investigator should contact 
the lead sponsor Principal Investigator for this study.  
If there are any specific questions regarding the completion of the SAE form, please contact your 
site monitor. 
Site Reporting to Institutional Review Board/Independent Ethics Committee 
The investigator must notify the local IRB which approved the trial of the event in accordance 
with applicable guidelines. 
Sponsor Reporting to Regulatory Authorities and Investigators 
All reportable SAEs, including narrative safety reports of overall findings or data from aggregate 
analyses, will be reported to the applicable regulatory authorities by the sponsor or designee in 
accordance with the local regulations as described in the safety review plan for this study. 
The reporting of SAEs will be conducted in accordance with ICH E2A (Clinical Safety Data 
Management: Definitions and Standards for expedited reporting) and regulatory guidelines. 
In addition, study endpoints described in Section 5.1 of the protocol that are serious adverse 
events will only be reported in the final clinical study report unless the event was unusual, 

Collaborative Research Study, Version 4: 06/29/21

University of Pennsylvania 
Page 51 of 69 
Confidential and Proprietary 
unexpected, and there is evidence suggesting a causal relationship between the study drug and 
the event (e.g., death from anaphylaxis). 
The sponsor will notify all participating Investigators of safety reports, in a blinded fashion, of 
potential serious risks as described in the safety review plan for this study.  
15 Statistical Plan 
Baseline characteristics, such as patient demographics, disease etiology, disease severity and 
factors present at time of listing for liver transplantation, will be compared between the 
terlipressin treatment group and the retrospective control group.  Categorical variables will be 
presented as proportions and percentages and compared using chi-squared or Fisher’s exact 
testing.  Continuous variables will be presented as means and standard deviations or medians and 
interquartile ranges.  Depending on the distribution of the variable, the Student’s t-test or 
Wilcoxon rank sum will be used for comparison.   
15.1 Primary Analysis 
The primary analysis will utilize mixed effects regression modeling to estimate changes in serum 
creatinine (SCr) over the study period, accounting for baseline SCr and the correlation structure 
between the repeated measures.  All potential confounders will be added to the model and 
sequentially removed if they do not confound the association between receipt of terlipressin and 
improvement in Scr.  Those confounders resulting in a ≥ 10% change in the coefficient for the 
association between terlipressin and improvement in SCr will be retained in the final model. For 
all generated models, Aikaike Information Criteria (AIC) scores will be calculated and 
compared. The model with the smallest absolute AIC value will be accepted as the most 
parsimonious and will be used as the primary model for the explanation of study results. As has 
been undertaken in other terlipressin studies in HRS, a least-squares means analysis will be 
conducted using a repeated-measures analysis of variance.  The results from this approach to the 
statistical analysis can then be directly compared to prior study results.   
15.2 Secondary Analyses 
A number of secondary outcomes will be examined for the study cohort.  These outcomes 
include the incidence of dialysis, mortality, and liver transplantation at day 30 and 90.  The 

Collaborative Research Study, Version 4: 06/29/21 
To Treat HRS-AKI Patients with Continuous Terlipressin Infusion 
 
University of Pennsylvania 
Page 52 of 69 
Confidential and Proprietary 
incidence of kidney transplant within one year of liver transplant will also be determined.  
Additionally, descriptive comparisons of SCr will be undertaken at day 30 and 90 of follow up 
and at 4 time points after receipt of liver transplantation (day 30, 90, 180 and 365) and also at 
similar time points for those patients who were transplant ineligible or did not undergo a 
transplant.  Incidence will be calculated as the number of new events during the observation 
period divided by the total persons at risk.  All statistical analyses will be conducted using Stata 
version 15.1 statistical software (StataCorp, College Park, TX).  Statistical significance will be 
declared for a two-sided hypothesis test if the P value was <0.05.  
15.3 Sample Size Considerations 
A formal sample size calculation is not applicable for the proposed study. However, at least 50 
subjects across more than 5-10 institutions may receive terlipressin treatment during the course 
of the intervention portion of the study.  For the comparison of the terlipressin treatment group 
and retrospective controls, we expect to have 50 subjects in the intervention group and 150 
subjects, assembled from the study sites, in the control group.  Assuming a type 1 error of 0.05 
and power of 80%, we expect to be able to detect a range of differences in serum creatinine (SCr) 
depending on the standard deviation of the change (primary endpoint) expected for the groups 
(see below).  Based on results from the REVERSE trial, a change in SCr of as small as 0.05 mg/ 
dL would be able to be detected if the standard deviation for the change approximated 0.10 
mg/dL and a pre-specified sample size of 200 subjects, 50 of whom are in the intervention arm, 
is used for the calculation.

Given the relatively small number of subjects proposed for inclusion in this terlipressin study, we 
will likely by underpowered to detect a difference in the other secondary outcomes being 
explored.

Page 53 of 69 
Confidential and Proprietary 
Safety variables will include the following: 
• Serious adverse events and all deaths.  Safety details may include: 
o Vital signs (body temperature, blood pressure, heart rate, respiratory rate, and SpO2). 
o MELD score. 
o Encephalopathy score. 
o Laboratory parameters. 
Serious Adverse events will be not classified by Medical Dictionary for Drug Regulatory 
Activities (MedDRA) system organ class, preferred term, severity, and seriousness.  SAEs will 
be summarized using site reported terminology, as well as by the investigator's assessment of the 
relationship of the SAE to the study drug. 
15.5 Subject Accounting and Baseline Characteristics 
A summary of the study completion status and reasons for discontinuation will be provided for 
both the Prospective Terlipressin Group and the Retrospective Control Group. Baseline 
characteristics (age, gender, race, etc.) will be summarized. The number of subjects with medical 
conditions within each body system will be reported. Summaries of the extent of exposure and 
protocol deviations will also be provided. 
15.6 Safety Population 
The safety population is defined as all subjects who received at least 1 dose of study drug. 
16 Direct Access, Data Handling, and Record Keeping 
16.1 Investigator 
The investigator will permit study-related monitoring, audits, IRB review, and regulatory 
inspections by providing direct access to original source data and documents. 
All subject information will be recorded on source documents. The CRFs must be fully 
completed and include all required data for all subjects enrolled. All CRF data must be submitted 
to the sponsor throughout and at the end of the study.

University of Pennsylvania 
Page 54 of 69 
Confidential and Proprietary 
If an investigator retires, relocates, or otherwise withdraws from conducting the study, the 
investigator must notify the sponsor to agree upon an acceptable storage solution. Regulatory 
agencies will be notified with the appropriate documentation. 
Any significant changes in study personnel will require an updated Statement of Investigator 
(e.g., FDA Form 1572) to be filed with the sponsor. 
The investigator must notify their IRB of protocol violations in accordance with local regulatory 
and IRB requirements. 
16.2 Sponsor 
The CRF data are stored in a database and processed electronically. The data are reviewed for 
completeness, and logical consistency. Requests for data clarification are forwarded to the study 
site for resolution. 
16.3 Records Retention 
The investigator shall retain and preserve 1 copy of all data collected or databases generated in 
the course of the study, specifically including but not limited to those defined by Good Clinical 
Practice (GCP) as essential. Essential documents should be retained until at least 2 years after the 
last approval of a marketing application in an ICH region and until there are no pending or 
contemplated marketing applications in an ICH region or at least 2 years have elapsed since the 
formal discontinuation of clinical development of the investigational medicinal product. 
These documents should be retained for a longer period, however, if required by the applicable 
regulatory requirements or by an agreement with the sponsor. It is the responsibility of the 
sponsor to inform the investigator/institution as to when these documents no longer need to be 
retained. Prior to destruction of any study essential documents, the investigator must first obtain 
written approval from the sponsor. 
17 Quality Control and Quality Assurance 
17.1 Study Monitoring 
The sponsor has ethical, legal, and scientific obligations to carefully follow this study in a 
detailed and orderly manner in accordance with established research principles and applicable 
regulations. The investigator, as part of his responsibilities, is expected to cooperate with the 
sponsor, or their designee International HealthCare, in ensuring that the study adheres to the 
protocol and GCP requirements. 

Collaborative Research Study, Version 4: 06/29/21 
To Treat HRS-AKI Patients with Continuous Terlipressin Infusion 
 
University of Pennsylvania 
Page 55 of 69 
Confidential and Proprietary 
As part of a concerted effort to fulfill these obligations (maintain current personal knowledge of 
the progress of the study), the sponsor's monitor will visit the center(s) during the study in 
accordance with the monitoring plan set forth for this study as well as maintain frequent 
telephone and written communication. The investigator will permit the sponsor to monitor the 
study as frequently as is deemed necessary and provide access to medical records to ensure that 
data are being recorded adequately, that data are verifiable, and that protocol adherence is 
satisfactory. 
17.2 Auditing 
The sponsor may conduct audits at the study center(s). Audits will include, but not be limited to, 
drug supply, presence of required documents, the informed consent process, and comparison of 
case report forms with source documents. The investigator agrees to participate with audits 
conducted at a reasonable time in a reasonable manner. 
Regulatory authorities worldwide may also audit the investigator during or after the study. The 
investigator should contact the sponsor immediately if this occurs and must fully cooperate with 
regulatory authority audits conducted at a reasonable time in a reasonable manner. 
18 Ethics and Responsibility 
This study will be conducted in compliance with the protocol, with the sponsor’s standard 
operating procedures and/or guidelines, with the FDA or local regulatory regulations, with the 
ICH GCP guidelines, and with the Declaration of Helsinki. 
18.1 Institutional Review Board/Independent Ethics Committee 
This protocol and the written informed consent form shall be submitted to the IRB identified 
with this responsibility at the research facility. Notification in writing of approval must come 
from the IRB chairman or secretary, to the investigator, either as a letter or as a copy of the 
appropriate section of the IRB meeting minutes where this protocol and associated informed 
consent form were discussed. The investigator will not participate in the decision. If the 
investigator is an IRB member, the written approval must indicate such non-participation. 
The investigator will submit status reports to the IRB at least annually (when applicable). 
The IRB must be notified by the investigator in writing of the interruption and/or completion of 
the study; the investigator must promptly report to the IRB all changes in research (protocol 
amendments) and will not make such changes without IRB approval except where necessary to 
eliminate apparent immediate hazards to human subjects. In these cases, the IRB must be 

Collaborative Research Study, Version 4: 06/29/21 
To Treat HRS-AKI Patients with Continuous Terlipressin Infusion 
 
University of Pennsylvania 
Page 56 of 69 
Confidential and Proprietary 
notified within 5 days of the change. The investigator will promptly report to the IRB all 
unanticipated problems involving risk to subjects or others. The investigator is required to 
maintain an accurate and complete record of all written correspondence to and received from the 
IRB and must agree to share all such documents and reports with the sponsor. 
18.2 Protocol Amendments 
Any change in the study plan requires a protocol amendment. An investigator must not make any 
changes to the study without IRB and sponsor approval except when necessary to eliminate 
apparent immediate hazards to the subjects. A protocol change intended to eliminate an apparent 
immediate hazard to subjects may be implemented immediately, but the change must then be 
documented in an amendment, reported to the IRB within 5 working days, and submitted to the 
appropriate regulatory agency in the required time frame. 
18.3 Informed Consent 
All subjects will have a signed document allowing the use of their medical data.  For the 
Prospective Terlipressin Group, written informed consent will be obtained from all subjects (or 
their guardian or legal representative) before any study-related procedures (including any pre-
treatment study-specific procedures) are performed. The investigator(s) has both ethical and legal 
responsibility to ensure that each subject being considered for inclusion in this study is given a 
full explanation of the protocol. This shall be documented on a written informed consent form, 
which shall be approved by the same IRB responsible for approval of this protocol. Each 
informed consent form shall include the elements required by regulatory regulations in 21 Code 
of Federal Regulations (CFR) Part 50 and ICH Guidance E6, Section 4.8. The investigator agrees 
to obtain approval from the sponsor of any written informed consent form used in the study, 
preferably prior to submission to the IRB.  
Once the appropriate essential information has been provided to the subject and fully explained 
by the investigators (or a qualified designee) and it is felt that the subject understands the 
implications of participating, the subject and the investigator (or designee) shall sign the 
IRB-approved written informed consent form. The subject shall be given a copy of the signed 
informed consent form, and the original shall be kept in the site’s regulatory file. A second copy 
may be filed in the subject's medical record, if allowed by the institution. 
18.4 Confidentiality 
All information generated in this study will be considered confidential and will not be disclosed 
to any persons not directly concerned with the study without written prior permission from the 

Collaborative Research Study, Version 4: 06/29/21

sponsor. However, authorized regulatory officials and sponsor personnel will be allowed full 
access to the records. All medications provided and subject bodily fluids and/or other materials 
collected shall be used solely in accordance with this protocol, unless otherwise agreed to in 
writing by the sponsor. 
Only initials and/or unique subject numbers in case report forms will identify subjects. Their full 
names may, however, be made known to a product regulatory agency or other authorized official 
if necessary. 
18.5 Subject Injury 
Subject injury provisions will be specified in the site’s Clinical Trial Agreement. 
18.6 Study Suspension, Termination, and Completion 
The sponsor or designee may suspend or terminate the study or part of the study at any time for 
any reason.  
If the investigator suspends or terminates the study, the investigator will promptly inform the 
sponsor or designee and the IRB and provide them with a detailed written explanation. The 
investigator will destroy all unused (after final drug accountability has been performed) and 
partially used investigational product per site standard operating procedure. Upon study 
completion, the investigator will provide the sponsor or designee, IRB, and regulatory agency 
with final reports and summaries as required by regulations. For IND application studies, or 
when the data will be used in support of an IND, the investigator must submit a written report to 
the sponsor or designee and the IRB within 3 months after the completion or termination of the 
study. Study termination and follow-up will be performed in compliance with applicable 
standard operating procedures. 
18.7 Study and Study Site Discontinuation Criteria 
The sponsor, investigator, medical monitor, or regulatory officials may discover conditions 
during the study that indicate that the study or study site should be terminated. This action may 
be taken after appropriate consultation between the sponsor and investigator. Conditions that 
may warrant termination of the study/study site include, but are not limited to: 
• The discovery of an unexpected, serious, or unacceptable risk to the subjects enrolled in 
the study.
