SYNOPSIS 
Study No.: GRASPANC 2018-01 
Title of Study: A Randomized, Phase 3 Study of Eryaspase in Combination with 
Chemotherapy versus Chemotherapy Alone as Second-Line Treatment in Patients with 
Pancreatic Adenocarcinoma 
Number of Study Centers: approximately 100 study centers 
Phase of Development: 3 
Objectives: 
Primary Objective: 
To determine whether the addition of eryaspase to chemotherapy improves overall survival 
(OS) in second-line treatment of pancreatic adenocarcinoma compared to chemotherapy alone. 
Secondary Objectives: 
• To compare progression-free survival (PFS) between the two treatment arms. 
• To compare the objective response rate (ORR) and duration of response (DoR) 
between the two treatment arms. 
• To compare the disease control rate (DCR) between the two treatment arms. 
• To evaluate the safety and tolerability of eryaspase in combination with chemotherapy 
versus chemotherapy alone.  
• To assess the effect of eryaspase on quality of life using the European Organization for 
Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC 
QLQ-C30). 
• To determine the pharmacokinetics of eryaspase. 
• To assess the immunogenicity of eryaspase in terms of the induction of anti-
asparaginase (ASNase) antibodies and neutralizing antibodies. 
• To evaluate the relationship of clinical outcome with relevant biomarkers and genetic 
changes present in tumor tissues and blood and/or serum samples. 
• To investigate the predictive relationship between the patient’s deoxyribonucleic acid 
(DNA) sequence variation, e.g. exploratory single nucleotide polymorphism [SNP] 
genotyping in select candidate genes, and their response to combination treatment in 
terms of safety and tolerability (pharmacogenetics [PGx]). 
Endpoints: 
Primary Endpoint: 
Overall Survival (OS) in the ITT population. 
Secondary Endpoints: 
• Progression-free Survival (PFS),  
• Objective Response Rate (ORR)

Trial Design/Methodology: 
This is an open-label, multicenter, randomized, Phase 3 study in patients with adenocarcinoma 
of the pancreas who have failed only one prior line of systemic anti-cancer therapy for 
advanced pancreatic cancer and have measurable disease as defined by the modified Response 
Evaluation Criteria in Solid Tumors (RECIST 1.1) criteria. After provision of informed 
consent and conduct of screening assessments, patients who meet all inclusion and no 
exclusion criteria will be randomized in a 1:1 ratio to one of the following treatment arms (see 
figure below): 
• Arm A (investigational arm): eryaspase in combination with either 
gemcitabine/Abraxane or irinotecan-based therapy (FOLFIRI [FOLinic acid-
Fluorouracil-IRInotecan regimen] or Onivyde®/5-fluorouracil/leucovorin), 
• Arm B (control arm): gemcitabine/Abraxane or irinotecan-based therapy (FOLFIRI or 
Onivyde/5-fluorouracil/leucovorin). 
 
 
The study will be divided into the following phases: 
• Screening Phase: Screening assessments should occur within 3 weeks of 
randomization for assessment of the patient’s overall eligibility. 
• Randomization Phase: Randomization will occur after the patient has been 
determined to be eligible.

Page 15 of 119 
• Treatment Phase: The first dose of chemotherapy will be administered within 3 days 
after randomization. Treatment will continue until objective disease progression, 
unacceptable toxicity, or the patient’s withdrawal of consent. Unacceptable toxicity is 
determined at investigator’s discretion, but as a guidance, unacceptable toxicity could 
consist of prolonged Grade 3 or 4 toxicity lasting more than 2 weeks. 
• In the investigational treatment arm (Arm A), eryaspase will be administered on Day 1 
and Day 15 of each 4-week cycle in combination with chemotherapy. Eryaspase will 
be administered by intravenous (IV) infusion over approximately 60 minutes, followed 
by one hour of rest and then followed by chemotherapy infusion. 
• Chemotherapy will be one of the following two treatment regimens: 
− Gemcitabine and Abraxane combination chemotherapy or 
− Irinotecan-based therapy: FOLFIRI (FOLinic acid-Fluorouracil-IRInotecan 
regimen) or Onivyde/5-fluorouracil (5-FU)/leucovorin (LV). 
• The choice of the chemotherapy regimen for a particular patient will be determined by 
the prior treatment received in the first-line setting. Thus: 
− If a patient received prior gemcitabine/Abraxane in the first-line setting, then on 
disease progression, the patient will be assigned to FOLFIRI (or 
Onivyde/5-FU/LV) in the current study. 
− If a patient received prior irinotecan-based therapy (FOLinic acid-Fluorouracil-
IRInotecan-Oxaliplatin; FOLFIRINOX), then on disease progression, the patient 
will be assigned to gemcitabine/Abraxane in the current study. 
• Follow-up Phase: Patients will be monitored for survival at 8-week intervals. Patients 
who discontinue treatment for reasons other than disease progression will continue to 
be assessed radiologically every 8 weeks until disease progression, or until withdrawal 
from the study, or death. 
Randomization will occur through an interactive web response system (IWRS). Patients will 
be randomized in a 1:1 ratio to chemotherapy with or without eryaspase. Randomization will 
be stratified according to the following factors: 
• Eastern Cooperative Oncology Group (ECOG) performance status (0 or 1), 
• Chemotherapy regimen in this study (gemcitabine/Abraxane or irinotecan-based 
treatment [FOLFIRI or its equivalent Onivyde/5-FU/LV]), and 
• Time interval since initial diagnosis of advanced disease to date of randomization in 
the study (<6 months or ≥6 months). 
An Independent Data Monitoring Committee (IDMC) will be established to review safety and 
efficacy data at regular intervals, including the interim and final analyses. 
In addition, the safety of eryaspase in combination with irinotecan-based therapy or 
gemcitabine/Abraxane regimen will be reviewed by the IDMC after at least 10 patients are 
enrolled per regimen and have received at least one cycle of study therapy. The specific 
responsibilities and composition of the IDMC will be outlined in a separate document, the 
IDMC Charter.

Safety and Efficacy Evaluations 
Assessments and timing of data collection are detailed in the Schedule of Events (Table 1). 
Safety Evaluations 
Clinical and laboratory parameters and adverse events will be assessed in all patients to 
evaluate disease status and toxicity. Patients will have safety assessments (laboratory tests, 
physical exams, vital signs including temperature, heart rate, and blood pressure, 
electrocardiograms [ECGs; to be performed during screening and then as clinically indicated], 
and performance status score) performed on Day 1 and Day 15 of each cycle and at the end of 
treatment. 
Adverse event reporting will begin at the time of informed consent signature. Adverse events 
and concomitant medications will be collected until 90 days after the last dose of study 
treatment, or until start of a new anti-cancer treatment whichever is sooner. 
Efficacy Evaluations 
Tumor assessments utilizing thoraco-abdominal computed tomography (CT)/magnetic 
resonance imaging (MRI) scans will be repeated every 8 weeks, calculated from the date of 
randomization, until disease progression, or until withdrawal from the study, or death. Every 
effort should be made to adhere to the assessment schedule. The same imaging technique must 
be used throughout the study. For patients who discontinue treatment for reasons other than 
objective disease progression, and patients who start new anti-cancer treatment without 
evidence for objective disease progression, disease status evaluation will continue to be 
repeated every 8 weeks, calculated from the date of randomization, until disease progression. 
All radiological images must be collected in a de-identified manner, quality controlled, stored, 
and available for future review, including independent radiological review as necessary. 
Survival information will be collected by phone, follow-up visit, or medical records review 
every 8 weeks from the date of the EOT visit until the patient’s death, until the patient is lost 
to follow-up, or until study closure. Survival follow-up information will include collection of 
any subsequent anticancer therapy received after discontinuation from study medication. 
Quality of life (QoL) assessment (EORTC QLQ-C30) will be performed, at Day 1 of each 
cycle prior to dosing, at the end of treatment visit and every 8 weeks during survival follow 
up. 
Pharmacokinetics, Pharmacodynamics, and Translational Research 
Where possible, blood and plasma samples will be collected in the eryaspase arm for 
pharmacokinetic (PK) (ASNase activity) and pharmacodynamic determination, and for 
immunogenicity evaluation. 
Blood/plasma samples for PK and pharmacodynamic assessments will be collected at the 
following time points of Cycles 1 and 3 of study treatment: Day 1 prior to eryaspase 
administration, at 5-10 minutes post-eryaspase-infusion, at 5-8 days post-infusion (at the 
Investigator’s discretion), and at Day 15 pre-dose. Samples will be analyzed for whole blood

and plasma concentrations of ASNase and amino acids. The sparse PK data will be combined 
with previous data as part of a Population PK (POP PK) analysis. 
Samples for assessment of anti-L-ASNase antibodies and neutralizing antibodies will be 
collected pre-dose at Cycle 1 Day 1 and Day 15, at Day 1 of every second cycle thereafter, 
upon determination of disease progression and at the End of Treatment (EOT) visit, as 
specified in the Schedule of Events (Table 1). 
Exploratory biomarker analyses will examine potential predictive biomarkers correlating with 
eryaspase activity. Tissue samples will be collected at study start. In addition, blood/plasma 
samples for biomarker analysis will be collected from all patients at Cycle 1 Day 1 and 
Day 15, at Day 1 of every second cycle thereafter, upon determination of disease progression, 
and at the EOT visit. 
A blood sample for pharmacogenetic (PGx) analysis will be obtained once during the study, 
preferably during the screening phase, for patients who consent to this optional procedure. 
Number of Patients: The target sample size is 482 patients.  
Criteria for Inclusion: 
A patient will be eligible for the study if all the following criteria are met: 
1. Must be 18 years of age or older. 
2. Must have histologically confirmed pancreatic adenocarcinoma. 
3. Must have Stage III or IV disease (see APPENDIX 1). 
4. Must have received one line of systemic chemotherapy in the advanced setting with or 
without targeted agents, immunotherapy, or radiotherapy for treatment of advanced 
pancreatic adenocarcinoma. NOTE: patients whose disease progresses on, or within 3 
months of neo(adjuvant) chemotherapy may be considered eligible 
5. Must have radiological evidence of disease progression following most recent prior 
treatment, defined as appearance of any new lesion or increase of >20% of one or more 
existing lesions. 
6. Must have measurable lesion(s) per RECIST version 1.1 by CT scan with contrast (or 
MRI, if the patient is allergic to CT contrast media). 
• Measurable disease may be in the field of prior irradiation; however, at least 
4 weeks must have elapsed between the completion of radiation therapy and the 
baseline scan documenting disease status. 
• Bone disease is considered radiologically measurable only if there is at least a 50% 
lytic component. 
NOTE: Bone disease consisting of blastic lesion only is not measurable. 
7. Archival or fresh tumor tissue must be available for evaluating relevant biomarkers. 
Formalin-fixed paraffin-embedded [FFPE] block preferred, or a minimum of 
10 unstained FFPE slides of one archived block is required.  NOTE: if archival tissue 
is unavailable and an elective biopsy can’t be scheduled due to COVID, this will be 
waived.

ovulation methods) and withdrawal are not acceptable methods of contraception] 
g. males with partners of childbearing potential must agree to use condoms  
NOTE: Since an indirect interaction between components of the oral contraceptives 
and ASNase cannot be ruled out, oral contraceptives are not considered acceptable as 
contraceptive methods in the current clinical trial. A method other than oral 
contraception should be used in women of childbearing potential. 
NOTE: All chemotherapeutic agents may be teratogenic and excreted in breast milk. 
Patients who are breast feeding should consider alternative methods.

d. Psychiatric illness/social situations or any other serious uncontrolled medical 
disorders in the opinion of the Investigator that would limit compliance with study 
requirements. 
Investigational Product, Dosage and Mode of Administration: 
Eryaspase is a dispersion for infusion of homologous (allogeneic) erythrocytes encapsulating 
recombinant E. coli L--ASNase, in a saline preservative solution. 
The dose of eryaspase is 100 U/Kg administered every two weeks (Day 1 and Day 15) until 
disease progression, unacceptable toxicity, or the patient’s withdrawal of consent. 
Eryaspase will be administered intravenously over approximately 60 minutes, followed by 
one hour of rest and then followed by chemotherapy infusions. 
Standard Chemotherapy dose and mode of administration: 
Gemcitabine plus Abraxane (albumin-bound paclitaxel) administered on Days 1, 8, and 15 
of each 4-week cycle as follows: 
• Abraxane (125 mg/m2) IV over 30-40 minutes followed by 
• Gemcitabine (1000 mg/m2) IV over 30 minutes. 
Onivyde (irinotecan nanoliposomal) + 5-FU/leucovorin administered on Days 1 and 15 of 
each 4-week cycle as follows: 
• Onivyde 70 mg/m2 IV over 90 minutes (recommended starting dose of Onivyde in 
patients homozygous for UGT1A1*28 is 50 mg/m2), 
NOTE: The approved dose of Onivyde is based on the NAPOLI-1[36] trial, in which 
Onivyde was given at a dose of 80 mg/m2 (i.e. equivalent of 70 mg/m2 of irinotecan 
free base). 
• Leucovorin 400 mg/m2 IV over 30 minutes, and 
NOTE: Modifications to the leucovorin dose per sites standard administration protocol 
may be allowed in the study following approval from the medical monitor. 
• 5-FU 2400 mg/m2 over 46 hours. 
FOLFIRI (irinotecan, 5-FU, and leucovorin) administered on Days 1 and 15 of each 4-week 
cycle as follows: 
• Irinotecan 180 mg/m2 IV infusion over 90 minutes (recommended starting dose of 
irinotecan in patients homozygous for UGT1A1*28 is 150 mg/m2), 
• Leucovorin 400 mg/m² IV infusion over two hours, 
NOTE: Modifications to the leucovorin dose per sites standard administration protocol 
may be allowed in the study following approval from the medical monitor. 
• 5-FU 400 mg/m² IV bolus injection over 2-4 minutes, immediately following 
leucovorin infusion, and 
• 5-FU 2400 mg/m² IV continuous infusion over 46 hours immediately following bolus 
5-FU (Days 1 and 2, and Days 15 and 16).

Rationale for Sample Size Estimation: 
With a power of 88.4% and an overall one-sided type I error of 2.5%, and including one 
interim analysis for efficacy with an O’Brien-Fleming-type stopping rule, a total of 390 deaths 
are required to detect a treatment effect hazard ratio of 0.725 for eryaspase plus chemotherapy 
versus chemotherapy alone. The interim analysis for efficacy will take place once 261 (67%) 
events have been observed.  
Assuming a recruitment period of 26 months, a median overall survival in the control group of 
6.0 months, a 10% probability of dropping out during the course of the study, and a minimum 
follow-up of 9 months, the study size will be based on the recruitment of 482 patients. 
 
Analysis Populations: 
Intent to Treat (ITT) population: All patients randomized, irrespective of whether they 
receive study medication. 
Safety population (SP): All randomized patients who receive at least one dose of study 
medication (eryaspase or chemotherapy). 
Per-Protocol (PP) population: The PP population is a subset of the ITT population, and 
consists of all randomized patients who meet the major inclusion criteria and none of the 
major exclusion criteria and who receive at least one cycle of treatment. 
Interim and Final Analyses: 
This study will have one interim analysis for superiority after 67% of the initial targeted 
numbers of events are observed.  
Primary Analysis: 
The primary analysis will be the comparison of OS between the two treatment arms in the ITT 
population using the one-sided stratified log-rank test, stratified for ECOG status, 
chemotherapy regimen, and time from diagnosis of advanced disease. 
Key Secondary Analyses: 
Progression-free survival (PFS) will be compared between the two treatment arms using the 
same method of analysis as for OS. 
The following efficacy analyses will also be performed in the ITT population: 
• ORR, defined as the proportion of patients who achieve objective tumor response 
(complete response [CR] or partial response [PR]) per RECIST 1.1. Each patient’s best 
overall response (BOR) will be summarized (CR, PR, stable disease [SD], progressive 
disease [PD], or unknown). 
• DCR (disease control rate), defined as the proportion of patients who achieve CR, PR 
and SD.

Version 2.0 (14th December 2020) 
CONFIDENTIAL AND PROPRIETARY 
 
Page 23 of 119 
• DoR will be evaluated in patients who achieve CR/PR. It will be measured from the 
time CR/PR (whichever is first recorded) is first met to until the first date that 
recurrence or PD is objectively documented. 
Extensive evaluation of the consistency of treatment effect for OS and PFS across the 
population as a whole will be undertaken by providing analyses in subgroups, with displays in 
forest plots and p-values for interaction. 
All efficacy analyses will be repeated in the PP population. 
Confirmatory testing for the primary and secondary efficacy endpoints will be performed 
hierarchically (OS followed by PFS followed by DCR followed by ORR) in order to account 
for multiplicity. Any statistically significant findings occurring below a non-significant result 
in the hierarchy will be considered as exploratory findings. 
Safety and tolerability of eryaspase in combination with chemotherapy versus chemotherapy 
alone will be assessed by analyzing AEs (incidence, intensity, seriousness, and causal 
relationship of AEs to the study drug, action taken following AE), drug exposure (duration of 
treatment), dosing information/compliance, concomitant medications, clinical laboratory 
results, ECG findings, vital signs, physical examination, body weight, ECOG PS, and 
treatment and study termination status data.

INTRODUCTION 
1.1 
BACKGROUND 
1.1.1 
Pancreatic Cancer 
Pancreatic adenocarcinoma (PAC) is one of the most aggressive and fatal malignancies, and is 
ranked as the seventh leading cause of cancer death.[2] The overall prognosis for PAC is poor, 
with a 5-year survival rate of 7%.[3] This is attributable to the difficulty of diagnosing pancreatic 
cancer in the early stages, poor tumor resectability, and poor response to chemotherapy.[4] 
Indeed, most patients with pancreatic cancer progress to either metastatic or locally advanced 
disease in the asymptomatic phase.[5] 
Current treatment strategies for non-resectable, metastatic disease focus on conventional 
cytotoxic therapies. Established first-line treatment options include gemcitabine-based 
chemotherapy, either alone or in combination with nab-paclitaxel, or the FOLFIRINOX regimen 
(a combination of leucovorin [LV], 5-fluorouracil [5-FU], irinotecan, and oxaliplatin).[5] 
Gemcitabine treatment results in only modest improvements in overall survival (OS) and quality 
of life (QoL).[6] While the FOLFIRINOX regimen has demonstrated a robust clinical benefit 
compared with gemcitabine,[7] this regimen should only be considered for patients with good 
performance status (Eastern Cooperative Oncology Group Performance Status [ECOG PS] 0 or 
1) due to considerable toxicity.[5 8] 
In the second-line setting, there remains a lack of consensus regarding the standard of care. 
Treatment options are dependent on the risk-benefit balance for the patient and the treatment 
received in the first line.[5] In 2017, treatment guidelines were updated to recommend that the 
combination of nanoliposomal irinotecan (Onivyde®) with fluoropyrimidine regimens (i.e., 
5-FU with LV) can be considered an active and tolerable treatment option in fit patients (ECOG 
PS ≥2) previously treated with gemcitabine-based therapy.[8 9] This combination extended 
survival by 1.9 months compared with patients treated with 5-FU in combination with LV.[10] 
No formal recommendations are available for patients who have progressed on first-line 
FOLFIRINOX; although gemcitabine is widely used in this setting, disease control is only 
achieved in one in 5 patients.[11] The limited efficacy provided by cytotoxic therapies is driving 
the need to identify novel targets for which to develop more effective therapeutic strategies.[4] 
1.1.2 
Tumor Cell Metabolism 
Targeting tumor cell metabolism is one of the prospective therapeutic approaches.[12] PAC is 
characterized by extensive reprogramming of cellular metabolism, which enables tumor cells to 
proliferate in a nutrient-poor, hypoxic microenvironment. The acquisition of activating mutations 
in the oncogenic KRAS (Kirsten rat sarcoma virus) gene, which are observed in more than 90% 
of PACs, is central to this process.[13] Mutations in KRAS mediate the reprogramming of 
metabolic pathways that allow continued cellular proliferation in the absence of nutrients 
required by normal cells.[14 15] However, such reprogramming leads to dependence on 
metabolites that are utilized through non-canonical metabolic pathways, distinguishing these 
cells from normal cells. One such dependency is on the amino acid glutamine, which fuels 
anabolic metabolism and maintains redox balance with PAC cells.[16 17] Glutamine deprivation

or inhibition of enzymes downstream of KRAS in this aberrant metabolic pathway results in 
suppression of PAC growth.[16] 
KRAS also regulates expression of amino acid transporters, which provide most of the biomass 
for growing cells.[18] This is despite the increased levels of glucose and glutamine consumption, 
which indicates that KRAS-mediated regulation of amino acid transporters is vital for tumor 
growth. In pancreatic cancer, KRAS has been shown to regulate macropinocytosis of proteins, 
yielding amino acids including glutamine and asparagine that may then enter the tricarboxylic 
acid cycle.[19] 
Although glutamine is important for many cellular processes, including anaplerosis and 
lipid/nucleotide synthesis through its catabolism to glutamate, asparagine is the only amino acid 
that requires glutamine for de novo synthesis. A non-essential amino acid, asparagine is 
synthesized from glutamine and aspartic acid by the enzyme asparagine synthetase (ASNS).[20] 
Enhanced ASNS expression is a mechanism through which PAC cells adapt to hypoxia and 
glucose deprivation.[21] ASNS protects PAC cells from apoptosis induced by glucose 
deprivation through suppression of JNK/SAPK activation.[21] 
Furthermore, it has also been demonstrated that KRAS, through ATF4 regulation, adapts amino 
acid uptake and asparagine biosynthesis.[22] As KRAS activation increases dependency on 
glutamine, knock-down of KRAS in low glutamine conditions results in poor clinical 
outcome.[22] Expression of ASNS – a target of ATF4 – has been identified as a key regulator of 
cancer cell proliferation, and contributes to apoptotic suppression, protein biosynthesis, and 
mTOR pathway activation.[22] Together, the modulation of glutamine and of asparagine levels 
leads to a critical vulnerability of PAC cells, which may be exploited in cancer therapeutics. 
1.1.3 
Asparaginase 
Asparaginase is a key component of multi-agent chemotherapy used in the treatment of 
childhood acute lymphoblastic leukemia (ALL). In ALL, as leukemic cells lack ASNS, ASNase 
exerts its anti-tumor effect through depletion of serum asparagine by catalyzing the deamination 
of asparagine to aspartic acid.[20] This starves susceptible cells of asparagine required for 
protein synthesis, which results in cell cycle arrest and, ultimately, apoptosis.[20 23] As 
glutamine also acts as a substrate for the enzyme,[24] ASNase treatment also depletes serum 
glutamine levels, contributing further to cell growth inhibition.[20] 
Several in vitro studies have demonstrated that reductions in both asparagine and glutamine 
levels are associated with inhibition of the mTOR pathway, which results in suppression of 
ribosomal protein synthesis.[25] Early experiments utilizing pancreatic cell lines demonstrated 
that inhibition of protein synthesis by ASNase could be reversed by supplementation with 
glutamine but not asparagine.[26] More recently, in cell lines expressing high levels of ASNS, 
glutamine was demonstrated to maintain the viability of cells in asparagine-deprived 
medium.[27] This suggests that glutaminase activity is an important component of the anti-tumor 
effect of ASNase, especially against tumors with high ASNS expression.[27] 
Despite this in vitro sensitivity, clinical studies in solid tumors have been limited due to the 
challenge of a narrow therapeutic index for ASNase. Excessive toxicity of native and pegylated 
ASNase (peg-ASNase) formulations has been observed in clinical studies of solid tumors 
(pancreatic, ovarian) and multiple myeloma.[28-30] Indeed, a recent phase 1 study evaluating

CONFIDENTIAL AND PROPRIETARY 
 
Page 35 of 119 
peg-ASNase in combination with gemcitabine in patients with metastatic solid tumors and 
lymphoma was terminated early due to toxicity.[31] 
1.2 
CLINICAL EXPERIENCE WITH ERYASPASE 
Encapsulation of ASNase within RBCs through a proprietary process is a novel approach to the 
delivery of ASNase at biologically effective doses with reduced propensity for toxic effects. The 
encapsulated ASNase remains biologically active, with a half-life of approximately two 
weeks.[32] It has been demonstrated that encapsulation has no effect on the permeability of 
RBCs to asparagine.[33] Thus, asparagine is actively transported across a concentration gradient 
into the RBC where it is de-aminated into aspartic acid and ammonia, depleting the serum of 
asparagine. It is postulated that the same process occurs with glutamine. 
Encapsulation prevents the rapid degradation of ASNase in the blood, thus prolonging activity, 
and limits exposure to the immune system, thus impeding its intrinsic immunogenicity, and in 
particular hypersensitivity reactions.[32] 
To date, five clinical trials have been conducted with eryaspase in pediatric and adult patients 
with ALL and acute myeloid leukemia (AML), and two clinical trials have been conducted in 
pancreatic cancer. The total number of patients treated thus far in the eryaspase clinical trial 
program is 307, as of a cut-off date of 28 Feb 2017. In the two studies in PAC, the total number 
of patients treated is 104. 
1.3 
ERYASPASE IN THE TREATMENT OF PANCREATIC CANCER 
The potential of eryaspase in advanced PAC is being evaluated. GRASPANC 2008-02, a Phase 1 
dose-escalation study, investigated eryaspase as a single agent in patients with metastatic PAC 
with at least two prior lines of therapy. Twelve patients received a single administration of 
eryaspase as monotherapy (25, 50, 100, or 150 U/Kg). No dose-limiting toxicity was reported. 
The recommended Phase two dose was determined to be 100 U/Kg every two weeks.[34] [35] 
GRASPANC 2013-03, a phase 2 trial in advanced PAC, was completed in 2017. This was a 
multicenter, open-label study investigating eryaspase in combination with gemcitabine or 
mFOLFOX6 (modified FOLinic acid-Fluorouracil-Oxaliplatin-6 regimen) as second-line 
treatment in patients with metastatic PAC. Patients were randomized in a 2:1 ratio to either 
eryaspase plus chemotherapy or chemotherapy alone, and were stratified according to 
chemotherapy regimen. The co-primary endpoints were progression-free survival (PFS) and 
overall survival (OS) in patients with low or no ASNS expression (ASNS 0/1+). Secondary 
endpoints included PFS and OS in the Intent to Treat (ITT) and high-ASNS expression 
(ASNS 2+/3+) populations, objective response, and toxicity. It should be noted that the study 
was not powered for the co-primary endpoints of PFS and OS. The conclusions regarding the 
efficacy of eryaspase when used in combination with gemcitabine or mFOLFOX6 chemotherapy 
in relation to these endpoints was to be based on observed hazard ratio (HR), with the study 
being considered positive if the HR for OS or for PFS was <0.85. 
A total of 141 patients were randomized, 95 to eryaspase plus chemotherapy and 46 to 
chemotherapy alone. The majority of patients (~90%) received gemcitabine during the study. 
Baseline demographics and disease characteristics were generally well-balanced between

treatment arms. Median age (range) was 63 years (37–84) in the eryaspase arm compared with 
63 years (43–80) with chemotherapy alone. 
Both co-primary endpoints were met in the ASNS 0/1+ subgroup (eryaspase, n = 66; control, 
n = 32), with HRs of 0.67 for PFS and 0.63 for OS, Table 2.

The objective response rate was also higher in the eryaspase arm (12.6%) compared to the 
control arm (6.5%), as assessed by independent radiological review. Notably, there was one 
patient who achieved complete response in the eryaspase arm, Figure 2 and Figure 3. Similarly, 
the disease control rate (DCR) was also higher in the eryaspase arm (48.4% compared with 
23.9% in the control arm).

Adverse events (AEs, Table 3) and serious adverse events (SAEs, Table 4) were slightly more 
frequent in the eryaspase arm; however, AEs resulting in treatment discontinuation and fatal 
outcomes were less frequent in the eryaspase arm. The safety profile of eryaspase added to 
chemotherapy revealed no unexpected findings, and eryaspase did not appear to add to the 
toxicity of chemotherapy.

STUDY RATIONALE 
PAC is characterized by aberrant metabolic pathways, such as constitutive activation of KRAS 
signaling, that utilize asparagine and glutamine to circumvent the hypoxic and nutrient-poor 
tumor microenvironment. Perturbation of these pathways through deprivation of glutamine and 
asparagine results in loss of cell viability. 
The potential benefit of ASNase therapy in PAC has been explored previously; however, these 
studies were stopped early due to the excessive toxicity of the ASNase.[28] 
In the Phase 2 GRASPANC 2013-03 study, eryaspase demonstrated clinical benefits in terms of 
OS, PFS, and objective response rate (ORR) in the second-line treatment of metastatic PAC. The 
study met its primary endpoints, and the benefits of eryaspase (in terms of OS and PFS) reached 
statistical significance in the ITT population. 
Given the results of this Phase 2, proof-of-concept study, eryaspase has the potential to add to the 
limited treatment options available for second-line PAC. 
1.5 
RISK/BENEFIT ASSESSMENT 
1.5.1 
Known Potential Risks 
Eryaspase is a combination of two recognized products, RBCs and ASNase, whose safety 
profiles are well documented. Thus, the potential toxicity of eryaspase may arise from 3 main 
mechanisms: ASNase, RBCs, or a combination of the two components. 
Please refer to the investigator’s Brochure (IB) for additional details. 
To date, there have been 8 clinical studies which have evaluated eryaspase in 307 patients. 
Specifically, two studies have been conducted in PAC, with eryaspase administered to 
104 patients. Table 5 shows the adverse events reported in >10% of patients in the combined 
eryaspase-treated populations (ALL, AML, PAC), regardless of severity or attribution to 
treatment. 
In the Phase 2 GRASPANC 2013-03 study, the safety profile of eryaspase added to 
chemotherapy revealed no unexpected findings, and eryaspase did not appear to add to the 
toxicity of chemotherapy.

The potential benefit for patients can be measured in terms of improvements in quality of life 
(QoL), OS, and PFS, factors associated with improved tumor control. The GRASPANC 2013-03 
study evaluated eryaspase in combination with chemotherapy in the second-line treatment of 
PAC. This study demonstrated improved OS and PFS in the ITT population, with an acceptable 
tolerability profile. 
1.5.3 
Assessment of Potential Risks and Benefits 
The potential benefit of ASNase therapy in PAC has been explored previously; however, these 
studies were stopped early due to the excessive toxicity of the ASNase.[28] 
In the Phase 2 GRASPANC 2013-03 study, eryaspase demonstrated clinical benefits in terms of 
OS, PFS, and ORR in the second-line treatment of metastatic PAC. 
The addition of eryaspase to chemotherapy did not lead to unexpected safety findings and did not 
appear to enhance the toxicity of chemotherapy. 
Overall, the potential benefits of eryaspase outweigh the expected risks of participation in the 
study.

STUDY DESIGN 
3.1 
OVERALL DESIGN 
This is an open-label, multicenter, randomized Phase 3 study in patients with adenocarcinoma of 
the pancreas who have failed only one prior line of systemic anti-cancer therapy for advanced 
disease and have measurable disease as defined by the Response Evaluation Criteria in Solid 
Tumors (RECIST 1.1) criteria. After provision of informed consent and conduct of screening 
assessments, patients who meet all inclusion and no exclusion criteria will be randomized in a 
1:1 ratio to one of the following treatment arms, Table 4: 
• Arm A (investigational arm): eryaspase in combination with either gemcitabine/Abraxane 
or irinotecan-based therapy (FOLFIRI [FOLinic acid-Fluorouracil-IRInotecan regimen] 
or Onivyde/5-fluorouracil/leucovorin), 
• Arm B (control arm): gemcitabine/Abraxane, or irinotecan-based therapy (FOLFIRI or 
Onivyde/5-fluorouracil/leucovorin). 
 
 
Figure 4 
Study Schema  
The study will be divided into the following phases: 
Screening Phase: Screening assessments should occur within 3 weeks of randomization for 
assessment of the patient’s overall eligibility. 
Randomization Phase: Randomization will occur after the patient has been determined to be 
eligible. 
Treatment Phase: The first dose of chemotherapy will be administered within 3 days after 
randomization. Treatment will continue until objective disease progression, unacceptable 
toxicity, or the patient’s withdrawal of consent. Unacceptable toxicity is determined at 
investigator’s discretion, but as a guidance, unacceptable toxicity could consist of prolonged 
Grade 3 or 4 toxicity lasting more than two weeks.

Page 47 of 119 
In the investigational treatment arm (Arm A), eryaspase will be administered on Day 1 and 
Day 15 of 4-week cycle in combination with chemotherapy. Eryaspase will be administered by 
intravenous (IV) infusion over approximately 60 minutes, followed by one hour of rest and then 
followed by chemotherapy infusion. 
Chemotherapy will consist of one of the following two treatment regimens: 
− Gemcitabine and Abraxane combination chemotherapy 
− Irinotecan-based therapy: FOLFIRI (FOLinic acid-Fluorouracil-IRInotecan regimen) 
or Onivyde/5-fluorouracil (5-FU)/leucovorin (LV) 
The choice of the chemotherapy regimen for a particular patient will be determined by the prior 
treatment received in the first-line setting. Thus: 
− If a patient received prior gemcitabine/Abraxane in the first-line setting, then on 
disease progression, the patient will be assigned to FOLFIRI (or Onivyde/5-FU/LV) 
in the current study. 
− If a patient received prior irinotecan-based therapy (FOLFIRINOX), then on disease 
progression, the patient will be assigned to gemcitabine/Abraxane in the current 
study. 
Follow-up Phase: Patients will be monitored for survival at 8-week intervals. Patients who 
discontinue treatment for reasons other than disease progression will continue to be assessed 
radiologically every 8 weeks until disease progression, or until withdrawal from the study, or 
death. 
Randomization will occur through an interactive web response system (IWRS). Patients will be 
randomized in a 1:1 ratio to chemotherapy with or without eryaspase. Randomization will be 
stratified according to the following factors: 
• ECOG Performance Status(PS) score (0 or 1), 
• Chemotherapy regimen in this study (gemcitabine/Abraxane or irinotecan-based 
treatment [FOLFIRI or its equivalent Onivyde/5-FU/LV]), and 
• Time interval since initial diagnosis of advanced disease to randomization date 
(<6 months or ≥6 months). 
An Independent Data Monitoring Committee (IDMC) will be established to review safety and 
efficacy data at regular intervals, including the interim and final analyses. 
In addition, the safety of eryaspase in combination with irinotecan-based therapy or 
gemcitabine/Abraxane regimen will be reviewed by the IDMC after at least 10 patients are 
enrolled per regimen and have received at least one cycle of study therapy. The specific 
responsibilities and composition of the IDMC will be outlined in a separate document, the IDMC 
Charter. 
Safety and Efficacy Evaluations 
Assessments and timing of data collection are detailed in the Schedule of Events in Table 1. 
Safety Evaluations 
Clinical and laboratory parameters and adverse events will be assessed in all patients to evaluate 
disease status and toxicity. Patients will have safety assessments (laboratory tests, physical

exams, vital signs including temperature, heart rate, and blood pressure, electrocardiograms 
[ECGs performed during screening and then as clinically indicated], and performance status 
score performed on Day 1 and Day 15 of each cycle and at the End of Treatment visit. 
Adverse event reporting will begin at the time of informed consent signature. Adverse events and 
concomitant medications will be collected until 90 days after the last dose of study treatment or 
until start of new anti-cancer treatment, whichever is sooner. 
Efficacy Evaluations 
Tumor assessments utilizing computed tomography (CT)/magnetic resonance imaging (MRI) 
scans will be repeated every 8 weeks, calculated from the date of randomization, until disease 
progression, or until withdrawal from the study, or death. Every effort should be made to adhere 
to the assessment schedule. The same imaging technique must be used throughout the study. 
Patients who discontinue treatment for reasons other than disease progression will continue to be 
assessed radiologically every 8 weeks until disease progression, or until withdrawal from the 
study, or death. For patients who discontinue treatment for reasons other than objective disease 
progression, and patients who start new anti-cancer treatment without evidence for objective 
disease progression, disease status evaluation will continue to be repeated every 8 weeks, 
calculated from the date of randomization, ,until disease progression. All radiological images 
must be collected in a de-identified manner, quality controlled, stored, and available for future 
review, including independent radiological review as necessary. 
Survival information will be collected by phone, follow-up visit, or medical records review every 
8 weeks from the date of the EOT visit  until the patient’s death, until the patient is lost to 
follow-up, or until study closure. Survival follow-up information will include collection of any 
subsequent anticancer therapy received after discontinuation from study medication. 
QoL (EORTC QLQ-C30) assessment will be performed, at Day 1 of each cycle prior to dosing, 
at the End of Treatment visit, and every 8 weeks during survival follow up. 
Blood and plasma samples will be collected in the eryaspase arm for pharmacokinetic (PK) and 
pharmacodynamic determination and for immunogenicity evaluation. 
Pharmacokinetics, Pharmacodynamics, and Translational Research 
Where possible, blood/plasma samples for PK and pharmacodynamic assessments will be 
collected at the following time points of Cycles 1 and 3 of study treatment: Day 1 prior to 
eryaspase administration, at 5-10 minutes post-eryaspsase infusion, at 5-8 days post-infusion (at 
the Investigator’s discretion), and at Day 15 pre-dose. Samples will be analyzed for whole blood 
and plasma concentrations of ASNase and amino acids. The sparse PK data will be combined 
with previous data as part of a Population PK (POP PK) analysis. 
Samples for assessment of anti-ASNase antibodies and neutralizing antibodies will be collected 
pre-dose at Cycle 1 Day 1 and Day 15, at Day 1 of every second cycle thereafter, upon 
determination of disease progression, and at the End of Treatment (EOT) visit, as specified in the 
Schedule of Events (Table 1). 
Exploratory biomarker analyses will examine potential predictive biomarkers correlating with 
eryaspase activity. Tissue samples will be collected at study start. In addition, blood/plasma 
samples for biomarker analysis will be collected from all patients at Cycle 1 Day 1 and Day 15,

at Day 1 of every second cycle thereafter, upon determination of disease progression, and at the 
End of Treatment (EOT) visit, as specified in the Schedule of Events (Table 1). 
A blood sample for pharmacogenetic (PGx) analysis will be obtained once during the study, 
preferably during the screening phase, for patients who consent to this optional procedure. 
An effective contraception must be used by all patients during eryaspase treatment and for at 
least 6 months after discontinuation from eryaspase treatment. Since an indirect interaction 
between components of the oral contraception and free ASNase cannot be ruled out (potential 
increase in the risk of a change in coagulation parameters and thrombosis), oral contraceptives 
are not considered sufficiently reliable when co-administered with ASNase products. A method 
other than oral contraception should be used in women of childbearing potential. 
3.2 
NUMBER OF PATIENTS 
The target sample size is 482 patients. 
3.3 
SCIENTIFIC RATIONALE FOR STUDY DESIGN 
3.3.1 
Choice of Chemotherapy (Control) 
There is currently no standard of care for locally advanced or metastatic pancreatic cancer that 
has progressed following either FOLFIRINOX or a gemcitabine-based regimen. While there are 
potential options, there is no proven benefit for any regimen, and treatment choice is generally an 
extrapolation from front-line studies. Based on systematic reviews and National Comprehensive 
Cancer Network (NCCN) guidelines, gemcitabine-based therapy can be given to those 
previously treated with fluoropyrimidine-based chemotherapy. Fluoropyrimidine-based 
chemotherapy regimens are acceptable second-line options for patients who received prior 
gemcitabine-based therapy. Based the recent Phase 3 NAPOLI-1 trial [36], Onivyde was 
approved by the Food and Drug Administration (FDA) and European Medicines Agency (EMA) 
in combination with 5-FU/leucovorin for use following gemcitabine-based therapy. Therefore, 
the choices of chemotherapy as the backbone of treatment in both treatment arms are justified. 
3.4 
JUSTIFICATION FOR DOSE 
The choice of dose and schedule for eryaspase (100 U/Kg given on Days 1 and 15 of each 4-
week cycle) is based on safety and tolerability data from the phase 1 monotherapy study in PAC 
patients [37]. This dose and schedule were evaluated in Study GRASPANC 2013-03, and have 
demonstrated encouraging signs of clinical benefit in terms of OS, PFS, and DCR in patients 
treated with eryaspase combined with chemotherapy compared to chemotherapy alone. 
The dosing schedule of chemotherapy agents will follow the label and standard practice for each 
respective agent.

10. Females of childbearing potential must have a negative pregnancy test at screening and 
additional negative pregnancy test prior to first dose. Males and females of childbearing 
potential must agree to use a highly effective method of contraception during treatment 
and for at least 6 months after the last dose of study treatment. These include, but not 
limited to: 
a. combined (estrogen and progestogen containing) hormonal contraception associated 
with inhibition of ovulation: 
i. intravaginal 
ii. transdermal 
b. progestogen-only hormonal contraception associated with inhibition of ovulation: 
i. injectable 
ii. implantable  
c. intrauterine device (IUD)  
d. bilateral tubal occlusion

[Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation 
methods) and withdrawal are not acceptable methods of contraception] 
g. males with partners of childbearing potential must agree to use condoms  
NOTE: Since an indirect interaction between components of the oral contraceptives and 
ASNase cannot be ruled out, oral contraceptives are not considered acceptable as 
contraceptive methods in the current clinical trial. A method other than oral contraception 
should be used in women of childbearing potential. 
NOTE: All chemotherapeutic agents may be teratogenic and excreted in breast milk. 
Patients who are breast feeding should consider alternative methods.

5.2 
DOSAGE AND ADMINISTRATION 
5.2.1 
Eryaspase 
At the treatment initiation, eryaspase will be prepared and dispatched after all screening 
assessments have been completed and the results reviewed and after it has been confirmed that 
the patient meets all eligibility criteria. 
The dose of eryaspase is 100 U/Kg, to be administered at Days 1 and 15 of each 4-week cycle 
until disease progression, unacceptable toxicity, or withdrawal of consent. 
Eryaspase is administered over approximately 60 minutes per bag, depending on the volume of 
the bag(s). The entire content of each bag is to be administered, unless otherwise specified. 
Eryaspase administration must be completed before the expiry time clearly stated on the label of 
the eryaspase bag. 
Date of administration, exact start and end times of infusion, and volume administered will be 
recorded on the Shipment and Administration Form (SAF) as described in the Investigational 
Medicinal Product (IMP) Manual and noted in the patient’s electronic Case Report Form 
(eCRF). 
Detailed instructions related to eryaspase administration and contact information in case of any 
issues are provided in the IMP Manual. 
5.2.2 
Gemcitabine and Abraxane 
Gemcitabine and Abraxane are to be administered on Days 1, 8, and 15 of each 4-week cycle as

5.2.3 
Irinotecan and 5-FU/Leucovorin 
Onivyde (irinotecan nanoliposomal) + 5-FU/leucovorin are to be administered on Days 1 and 
15 of each 4-week cycle as follows: 
• Onivyde 70 mg/m2 IV over 90 minutes (recommended starting dose of Onivyde in 
patients homozygous for UGT1A1*28 is 50 mg/m2), 
NOTE: The approved dose of Onivyde is based on the NAPOLI-1[36] trial, in which 
Onivyde was given at a dose of 80 mg/m2 (i.e. equivalent of 70 mg/m2 of irinotecan free 
base). 
• Leucovorin 400 mg/m2 IV over 30 minutes, and 
NOTE: Modifications to the leucovorin dose per sites standard administration protocol 
may be allowed in the study following approval from the medical monitor. 
• 5-FU 2400 mg/m2 over 46 hours. 
 
FOLFIRI (irinotecan, 5-FU, and leucovorin) is to be administered every 2 weeks on Day 1 
and Day 15 of each 4-week cycle as follows: 
• Irinotecan 180 mg/m2 IV infusion over 90 minutes (recommended starting dose of 
irinotecan in patients homozygous for UGT1A1*28 is 150 mg/m2) 
• Leucovorin 400 mg/m² IV infusion over 2 hours  
NOTE: Modifications to the leucovorin dose per sites standard administration protocol 
may be allowed in the study following approval from the medical monitor. 
• 5-FU 400 mg/m² IV bolus injection over 2-4 minutes, immediately following leucovorin 
infusion, and 
• 5-FU 2400 mg/m² IV continuous infusion over 46 hours, immediately following bolus 
5-FU. 
5.2.4 
Guidelines for Treatment Discontinuation and Dose Modification 
Patients will be treated until disease progression, unacceptable toxicity as determined by the 
Investigator, or withdrawal of consent. Each patient will be evaluated for drug-related toxicity. If 
a patient experiences unacceptable toxicity for more than two weeks, then such patients should 
be withdrawn from study treatment. Unacceptable toxicity will be determined at the 
investigator’s discretion; however, as a guidance, unacceptable toxicity could consist of 
prolonged Grade 3 or 4 toxicity not resolving within two weeks. The medical monitor must be 
consulted if any patient requires further treatment delays or dose modifications. 
Throughout the study, the following toxicity criteria will be used to guide treatment 
modifications and treatment delays. However, standard practice at sites may also be referred to, 
particularly for any of the chemotherapy components.  
Appropriate supportive care will be provided for the management of drug-related toxicities.  
In the instance of adverse events that require course changes, then the general guidance is 
delaying dose as opposed to skipping a dose. This could mean that a cycle could be longer than 
4 weeks.

5.2.4.1 
DOSE MODIFICATION FOR ERYASPASE 
One 25% dose reduction of eryaspase is permitted at the first occurrence of an eryaspase-related 
toxicity. Additional dose reduction to 50% is allowed on second instance. If further dose 
reductions are necessary, then eryaspase should be discontinued. 
Table 6 presents guidelines for carrying out eryaspase dose reductions when deemed appropriate. 
Dose reduction approach will depend on whether the drug is at site and ready for infusion 
(during a cycle) or is planned for a subsequent cycle. Dose reduction during a cycle will follow 
an empirical estimation of the volume in the eryaspase bag. Dose reduction in subsequent cycles 
will be reflected in the prescription form and will therefore be carried out by reducing the dose 
level per unit of body weight to be used in manufacturing the drug for the next cycle(s).

After a dose reduction, the dose of eryaspase may be re-escalated to the previous higher dose 
level, provided that toxicity resolves to at Grade 1 (or 2 where specified). 
Treatment with eryaspase may be delayed for up to 2 weeks at the first instance of an eryaspase-
related toxicity to allow for resolution of toxicity, defined as a return to ≤Grade 2, where 
indicated. The sponsor’s Medical Monitor must be consulted if any patient requires further 
treatment delays or dose modifications. If eryaspase-related adverse events do not resolve after a 
period of 2 weeks, the patient should discontinue eryaspase and should then complete the EOT 
visit and Follow-up visits per the Schedule of Events (Table 1). 
5.2.4.2 
DOSE MODIFICATIONS FOR CHEMOTHERAPY (WITH OR 
WITHOUT ERYASPASE) 
The product labeling information and local institutional practice should be referred to regarding 
hematological and non-hematological AEs attributable to the individual chemotherapy agents 
used in this study. In addition, it is recommended that patients receive pre-medication according 
to respective product labeling information. In case of Abraxane and Onivyde, pre-medication 
standard doses of dexamethasone (or an equivalent corticosteroid) together with a 5-
hydroxytryptamine 3 (5-HT3) antagonist (or other antiemetic) at least 30 minutes prior to start of 
chemotherapy infusion. 
5.2.4.2.1 
DOSE MODIFICATIONS FOR GEMCITABINE AND ABRAXANE 
Table 7 presents a summary of dose modifications for gemcitabine, Abraxane, and eryaspase. 
Patients who experience adverse events will be re-evaluated weekly, or more often according to 
the Investigator’s discretion. Dose delays or reduction for gemcitabine or Abraxane follow the 
respective prescribing information, and are provided in the table below for ensuring consistency

across sites. If toxicities do not resolve within two weeks, then the patient will discontinue the 
study treatment, but will continue to be followed for 90 days or until start of new anti-cancer 
treatment, whichever is first, for adverse events and serious adverse events. Thereafter, the 
patient will be followed for radiological disease assessment and survival until withdrawal from 
study or death.

DOSE MODIFICATIONS FOR IRINOTECAN AND 
5-FU/LEUCOVORIN 
Table 8 presents a summary of dose modifications for irinotecan, Onivyde, and eryaspase. 
Patients who experience adverse events will be re-evaluated weekly, or more often according to 
the Investigator’s discretion. Dose delays or reductions for irinotecan or Onivyde follow the 
respective prescribing information, and are provided in the table below for consistency across 
sites. If toxicities do not resolve to ≤Grade 2 within two weeks, then the patient will discontinue 
the study treatment, but will continue to be followed for 90 days or until start of new anti-cancer 
treatment, whichever is first, for adverse events and serious adverse events. The patient will be 
followed for radiological disease assessment and must complete an EOT visit and Follow-up 
visits per the Schedule of Events (Table 1). 
Following 5-FU treatment, mucositis, stomatitis, hand-foot syndrome, and diarrhea occur most 
commonly. Leukopenia is the usual dose-limiting toxicity after IV bolus administration. Patients 
with dihydropyrimidine dehydrogenase deficiency (DPD) are at risk of severe life-threatening 
toxicity with 5-FU. While severe deficiency is rare, 3-4% of the population has some degree of 
DPD deficiency. Patients with DPD deficiency cannot be enrolled in the 5-FU arm unless they 
have tolerated full doses of 5-FU previously. In general, dose modifications and delays follow a 
similar approach to that used with irinotecan. However, in case of mucositis or stomatitis, only 
5-FU (and not irinotecan or eryaspase) should be withheld during the cycle, and resumed at full 
dose in subsequent cycles.

5.2.5 
Management of Events of special Interest 
Hypersensitivity reactions have been reported with Abraxane, irinotecan, Onivyde, and 
eryaspase. All patients should be pretreated with corticosteroids, diphenhydramine, and H2 
antagonists as per institutional protocols. 
Eryaspase is an ASNase encapsulated into RBCs; therefore, the risk of allergic reactions is 
potentially attributed to one or more of the following causes: a) antibody-mediated clinical 
hypersensitivity reactions; b) non-antibody-mediated infusion reactions attributed to ASNase; 
and/or c) the RBC component in eryaspase. 
5.2.5.1 
MANAGEMENT OF HYPERSENSITIVITY REACTIONS WITH 
ERYASPASE OR OTHER AGENTS 
Generally, eryaspase does not require premedication for hypersensitivity reactions. However, 
eryaspase contains E. coli-derived ASNase, which has been associated with hypersensitivity 
reactions. These reactions range from local rash or flushing to severe systemic reactions with 
features such as urticaria, bronchospasm, angioedema, and severe anaphylactic shock. In the 
eryaspase program, there had been 15 (4.8%) Grade 3 or 4 allergic reactions as of 28 Feb 2017. 
The following is guidance for the treatment of hypersensitivity reactions. Treatment should be 
based on clinical presentation and is at the Investigator’s discretion. Institution-specific pre-
medication and/or treatment plans may also be followed if appropriate. 
Grade 2 Symptoms: 
• Stop administration.

If persists, discontinue.  
(1) For patients starting irinotecan at a reduced dose of 150 mg/m2 due to the presence of UGT1A1*28 
homozygous allele, dose should be reduced to 120 mg/m2 at first occurrence and an additional decrease of 
about 20% at the second occurrence of toxicity. 
(2) Onivyde dose reductions are presented based on a starting dose of 70 mg/m2 irinotecan free base (equivalent 
to 80 mg/m2 of Onivyde).  
(3) For patients starting Onivyde at a reduced dose of 50 mg/m2 irinotecan free base due to the presence of 
UGT1A1*28 homozygous allele, dose should be reduced to 43 mg/m2 at first occurrence and to 35 mg/m2 at 
the second occurrence. 
(4) Treatment with eryaspase can be resumed, provided that it is within shelf-life and the infusion is completed 
within the 6-hour window of bringing eryaspase to room temperature. 
(5) For mucositis or stomatitis, decrease only 5-FU, not irinotecan and not eryaspase.

• Administer IV dexamethasone 10 mg and diphenhydramine hydrochloride (HCL) 25 to 
50 mg. 
• After recovery of symptoms, treatment may be resumed once the patient is stable, if the 
product is not expired and the bag has been out of the cold box for less than 6 hours. 
• Use premedication for subsequent infusions of eryaspase. 
Grade 3 and 4 Symptoms (such as hypotension, angioedema, or respiratory distress): 
• Stop administration. 
• Administer IV dexamethasone 10 mg and diphenhydramine HCL 25 to 50 mg. 
• Add adrenaline or bronchodilators as indicated. 
• For Grade 4 toxicity, the treatment should be discontinued. 
Example of Infusion Premedication Regimen: 
• Dexamethasone 12 mg PO and diphenhydramine HCL 25-50 mg PO approximately 6 to 
12 hours prior to the next dose of eryaspase. 
5.2.5.2 
MANAGEMENT OF INFUSION/TRANSFUSION REACTIONS 
Allogeneic blood transfusions are associated with immune-related effects in the form of 
alloimmunization due to the exposure to alloantigens, cytokines, or other cellular components. 
Transfusion reactions are typically classified into the following entities [38]: i) transfusion-
related lung injury (TRALI); ii) volume overload in susceptible patients with cardiovascular 
problems ; iii) bacterial contamination; iv) acute hemolytic reactions, either immune-related with 
ABO incompatibility or non-immune related (for example, concomitant medications causing 
RBC hemolysis, incorrect storage of RBCs, or non-validated administration systems); 
v) non-hemolytic febrile reactions due to cytokines and other allo-proteins; and vi) allergic 
reactions, mostly related to unidentified allergens in the donor blood. 
Overall, eryaspase-related transfusion/infusion events have been reported in 25 (8.1%) patients 
enrolled in the combined clinical development program. None of these events were Grade 4 or 
fatal. Eryaspase utilizes leuko-depleted packed RBCs; its manufacturing process additionally 
helps to wash away any remaining leukocytes. Alloimmunization (switch from negative to 
positive anti-erythrocyte irregular antibodies) has been observed in 14.6% of patients (45 out of 
307) as of 28 Feb 2017. 
Management of transfusion/infusion reactions follows well-known published guidelines, as 
summarized in these publications [39-41]. It is recommended that Investigators follow 
institutional and local practice guidelines. Table 9 provides a summary of patient management 
for transfusion reactions.

5.2.5.3 
MANAGEMENT OF DIARRHEA 
Diarrhea is commonly reported with irinotecan and Onivyde, which typically has an onset in 
≤24 hours after starting Onivyde (early onset). A late onset (>24 hours) diarrhea has also been 
reported. When appropriately managed with anti-diarrheal treatment, diarrhea is generally mild 
to moderate. 
These broad general management principles are provided as a guideline to proactively avoid 
serious complications of diarrhea syndrome. These guidelines do not replace sound clinical 
judgment. 
In the event of diarrhea, patients should take loperamide at initial 4 mg dose, followed by 2 mg 
doses every 4 hours until 12 hours have lapsed without symptoms. Patients should be advised to 
increase fluid intake (water, sports drinks, clear juices, decaffeinated tea), and modify diet 
(banana, rice, apples and toast). 
• If mild to moderate diarrhea persists for more than 12 hours, loperamide should be taken 
at a dose of 2 mg every 2 hours 
• If mild to moderate diarrhea persist after 24 hours despite treatment with loperamide, a 
cocktail of atropine-diphenoxylate (Lomotil) and loperamide may be considered. 
Loperamide 2 mg may be alternated with one tablet of Lomotil every 3 hours. 
Loperamide should not be used for more than 48 consecutive hours due to risk of 
paralytic ileus. Oral antibiotic support (e.g. fluoroquinolone for 7 days) should be also 
considered. If diarrhea persists for more than 48 hours, loperamide should be stopped, 
and fluid replacement should be considered.

For Grade 3 or 4 diarrhea or complicated Grade 1 or 2 (severe cramping, severe 
nausea/vomiting, decreased performance status, fever, sepsis, Grade 3 or 4 neutropenia, frank 
bleeding, dehydration), IV fluids should be used as appropriate, as well as prophylactic 
antibiotics.

Acquisition and Accountability 
5.3.1.1 
ACQUISITION 
Eryaspase will be dispatched to the site only after receipt of the required information in 
accordance with ERYTECH procedures. 
• Information to be provided at study start: RBCs phenotype (including D, C, E, c, e, K 
and other antigens tested as per site practice), ABO blood group status, and Rhesus 
factor, all assessed on two separate samples, which can be collected on the same day. In 
addition, provide  historical results of an irregular antibody screening test (IAST), if 
available. This information is required at least 5 working days before the first infusion. 
• Prior to Cycle 1 Day 1 and each eryaspase dose: A prescription form indicating patient 
identifiers and body weight should be provided at the latest 5 working days prior to Cycle 
1 Day 1 (for all patients) and each eryaspase infusion (patients in eryaspase arm). 
• Information to be provided during the treatment phase: Results of IAST performed 
for previous eryaspase dose to be provided at the latest 5 working days prior to 
subsequent eryaspase infusion.  
• The following information is required before eryaspase can be shipped to the site: 
− The name and contact details of the recipient, who should be the investigator or 
designee. 
− The location for delivery (local pharmacy or blood bank). 
Detailed instructions for completing and providing the phenotype, blood group, and Rhesus 
factor information, the IAST results (from the previous infusion), and the prescription form are 
provided in the IMP manual. 
Eryaspase will be shipped to the Investigator in a qualified container by a specialized carrier, 
who will ensure that the cold chain is maintained between +2-8°C (35-46°F). 
If a temperature excursion outside the range of +2°C to +8°C (35-46°F) occurs, the product 
should be quarantined and ERYTECH Pharma should be contacted to determine the usability of 
the product. 
If it is not used immediately after receipt, it is mandatory that eryaspase be stored at temperatures 
between +2 and +8°C (35-46°F). 
Eryaspase may be stored at room temperature for up to 6 hours prior to administration, including 
infusion time; it must not be stored at room temperature for more than 6 hours.

5.3.1.2 
ACCOUNTABILITY 
The Investigator or designee is responsible for IMP accountability, reconciliation, and record 
maintenance (i.e., records of receipt, reconciliation, and final disposition). 
Further guidance and information concerning the final disposition of unused IMP are provided in 
the IMP Manual. 
5.3.2 
Formulation, Appearance, Packaging, and Labeling 
Please refer to the IB for details of eryaspase formulation and appearance. 
Eryaspase is packed in medical-grade polyvinyl chloride (PVC) blood bags according to GMP 
requirements and place in a photoprotective pocket. The final volume of the eryaspase bag 
depends on the patient’s weight and the dose prescribed. The volume of the bag ranges from 
50 mL to 300 mL depending on the individual patient’s dose (multiple bags may be required to 
achieve the full dose). 
Three (3) removable segment-tubes are attached to the bag for use in blood compatibility testing 
before administration. 
Label statements are specific to the clinical trial and comply with legal requirements for IMPs. 
The date and time of eryaspase expiration will be noted on the label. In addition, the label 
displays specific information necessary for traceability of source cell material and medicinal 
product (blood bank identifier for original RBCs, phenotype, patient identification number, etc.) 
to allow verification of the patient’s identity and blood group before administration. 
5.3.3 
Preparation 
Prior to eryaspase administration, an IAST and a complete compatibility test (cross-match test) 
between the patient’s blood and eryaspase, using the removable segment tubes, must be 
performed to confirm compatibility. In case a patient receives multiple bags of eryaspase to 
achieve the intended prescribed dose, separate cross-match tests must be performed with each 
eryaspase bag to confirm compatibility. 
Eryaspase should not be transferred to another container before infusion. Eryaspase should not 
be mixed or administered simultaneously with any other products, solutions, or medicinal 
products. 
After eryaspase administration, partially administered and empty bags may be destroyed locally 
under the biomedical waste disposal process as approved by the specific institution. However, in 
case of a product defect or quality issue, ERYTECH must be contacted for further instruction. 
Additional details will be described in the IMP Manual. 
Detailed instructions related to eryaspase administration and contact information in case of any 
issues are provided in the IMP Manual.

5.4 
MEASURES TO MINIMIZE BIAS: RANDOMIZATION AND BLINDING 
5.4.1 
Blinding 
 The study is an open-label pivotal trial. Investigators and patients will be unblinded to the 
treatment due to the nature of the investigational therapy. 
5.4.2 
Randomization 
Patients will be randomized to receive either chemotherapy in combination with eryaspase or 
chemotherapy alone in a 1:1 ratio, using an IWRS. At screening, the IWRS system will assign a 
unique patient number that will remain constant over the duration of the study. If a patient is 
rescreened after initial screen failure, the IWRS will allocate the same number. Treatment arm 
will be automatically determined by the IWRS system. Detailed instructions will be provided in 
the IWRS manual. 
Randomization will be stratified by these factors: 
• ECOG PS score (0 or 1), 
• Chemotherapy regimen (gemcitabine plus Abraxane or irinotecan-based therapy 
[FOLFIRI or Onivyde, 5-FU, and leucovorin]), and 
• Time interval since diagnosis of advanced disease to date of randomization in the study 
(<6 months or ≥6 months). 
5.5 
COMPLIANCE WITH STUDY TREATMENT 
Eryaspase will be administered by IV infusion under the supervision of study personnel. 
Compliance with the treatment dose and schedule will be documented in the source documents 
and recorded in the eCRF. 
5.6 
CONCOMITANT THERAPY 
For this protocol, a prescription medication is defined as a medication that can be prescribed only 
by a properly authorized/licensed clinician. All prescription medications, over-the-counter 
medications, and supplements used concomitantly or within 14 days prior to Cycle 1 Day 1 must 
be reported in the eCRF. 
5.6.1 
Prior Medications 
All treatments received within 14 days prior to Cycle 1 Day 1 will be recorded in the eCRF, 
including the name of the drug, route, indication, start date, and stop date (if applicable). In 
addition, any and all prior therapies for the treatment of pancreatic cancer (or cancer-related 
events such as bone pain) will also be recorded in the eCRF. 
5.6.2 
Permitted Medications 
Patients may receive supportive care for disease-related symptoms and for toxicity associated 
with study treatment. The date of supportive medication administration as well as the name and 
dosage regimen of each medication must be recorded in the eCRF.

Page 76 of 119 
The following treatments are permitted during the study: 
• Transfusion of blood products. 
Transfusion of fresh frozen plasma should be minimized, as it provides an exogenous 
source of asparagine. It is preferable to administer antithrombin III (AT III) concentrates 
in case of a decrease in AT III following eryaspase administration. Hemoglobin must be 
≥9 g/dL at Cycle 1 Day 1 and must be ≥8 g/dL before all subsequent doses. If 
hemoglobin is <8 g/dL, then appropriate measures must be taken according to standard 
clinical practice prior to further administration of chemotherapy. 
• Systemic and inhaled steroid treatment. 
A standard 3- to 5-day course of dexamethasone following the institutional standard of 
care is permitted for the prevention of treatment-induced nausea and vomiting. In 
addition, oral glucocorticoids at a daily dose of 1.5 mg dexamethasone (or equivalent) are 
permitted. 
• Palliative radiotherapy (e.g., for painful bone metastases). 
• Prophylactic granulocyte colony-stimulating factor (GCSF) in case of neutropenia. 
Details and indications for use of GCSF should follow American Society for Cooperative 
Oncology (ASCO) guidelines [42]. 
5.6.3 
Prohibited Medications 
During the treatment phase, the following treatments are prohibited: 
• Concomitant vaccination with live vaccines, due to increased risk of serious infection. 
Immunization with live or live-attenuated vaccines should take place no earlier than 
3 months after completion of eryaspase treatment. 
• Other L-ASNase products. 
• Highly hemolytic agents that may lead to RBC hemolysis: acetanilide, antipyrine 
(phenazone), and chloroquine and derivatives. 
• Prophylactic phenytoin.

DISCONTINUATION OF STUDY TREATMENT AND PARTICIPANT 
WITHDRAWAL FROM THE STUDY 
6.1 
DISCONTINUATION OF STUDY TREATMENT 
Discontinuation from eryaspase and/or chemotherapy treatment does not imply discontinuation 
from the study, and remaining study procedures should be completed as indicated by the study 
protocol. 
If a clinically significant finding is identified after enrollment, the investigator or qualified 
designee will determine whether any change in patient management is needed. Any new 
clinically relevant finding will be reported as an adverse event (AE). 
A patient may be withdrawn from treatment for any of the following reasons: 
• Unacceptable toxicity. 
• Objective disease progression following radiological assessment as determined by the 
investigator (per modified RECIST 1.1 criteria). 
• Patient’s withdrawal of consent for treatment. 
• Pregnancy 
• Investigator’s decision for other reasons, with documentation of reason(s) if not 
included in any of the above categories. 
NOTE: Clinical progression must be confirmed radiologically before treatment 
discontinuation and patient withdrawal. 
• Sponsor’s decision, including discontinuation of the study, with documentation of 
reason(s) in the eCRF. 
The reason for withdrawal will be recorded in the eCRF. 
The EOT visit must be performed and documented within 30 days after the last dose of eryaspase 
or chemotherapy. AEs/SAEs and concomitant medications must be collected up to 90 days after 
the last dose of study treatment or until start of new anti-cancer treatment, whichever is first. For 
details of the assessments to be performed, refer to the Schedule of Events (SOE), Table 1. 
6.2 
PARTICIPANT WITHDRAWAL FROM THE STUDY 
A patient may be withdrawn from the study for the following reasons: 
• Patient’s withdrawal of consent for the study. 
• Loss to follow-up. 
• Death. 
• Sponsor’s decision, including discontinuation of the study. 
The reason for withdrawal will be recorded in the eCRF. 
If a patient withdraws from the study during treatment, it is recommended that the EOT visit be 
performed and documented within 30 days if possible. For details of the assessments to be 
performed, refer to the SOE, Table 1.

Page 78 of 119 
If a patient withdraws from the study, the Investigator must make every effort to follow 
safety events to resolution, until the events stabilize, or until the patient’s death. 
If the patient withdraws consent for disclosure of future information, the Sponsor may retain and 
continue to use any data collected before such a withdrawal of consent. 
If a patient withdraws from the study, he/she may request destruction of any samples that have 
been taken but not yet tested, and the Investigator must document this request in the site’s study 
records and inform the Sponsor within 5 working days. 
 
6.3 
LOST TO FOLLOW-UP 
A patient will be considered lost to follow-up if he or she fails to return for scheduled visits and 
cannot be contacted by the study site staff. 
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit: 
• The site will attempt to contact the patient and reschedule the missed visit within 
one week, will counsel the patient on the importance of maintaining the assigned visit 
schedule, and will ascertain whether the patient wishes to and/or should continue in the 
study. 
• Before a patient is deemed lost to follow-up, the Investigator or designee must make 
every effort to regain contact with the patient (where possible, 3 telephone calls and, if 
necessary, a certified letter [or local equivalent] to the patient’s last known mailing 
address). These contact attempts should be documented in the patient’s medical record or 
study file. 
• Should the patient continue to be unreachable, he or she will be considered to have 
withdrawn from the study with a primary reason of loss to follow-up. 
 
6.4 
STUDY TERMINATION 
The Sponsor reserves the right to close the investigational site or terminate the study at any time 
for any reason. If the study is terminated, the Sponsor will notify the Investigators in writing. If 
the study is prematurely terminated or suspended, the Investigator will promptly inform study 
participants and the relevant IEC/IRB, and the Sponsor will provide the reason(s) for the 
termination or suspension to competent regulatory authorities. Study participants will be 
contacted as appropriate and will be informed of any changes to the study visit schedule. 
The Investigator may initiate site closure at any time, provided there is reasonable cause and 
sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of an investigational site by the sponsor may include but are not 
limited to: 
• Failure of the Investigator to comply with the protocol, the sponsor’s procedures, or 
Good Clinical Practice (GCP) guidelines.

STUDY ASSESSMENTS AND PROCEDURES 
Screening and study procedures and their timings are summarized in the Schedule of Events 
(SOE) in Table 1. 
Adherence to the study requirements, including those specified in the SOE, is essential and 
required for study conduct. Protocol waivers or exemptions are not allowed (with the exception 
of those in response to immediate safety concerns). 
All screening evaluations must be completed within 3 weeks prior to randomization, with 
confirmation that the patient continues to meet eligibility criteria prior to dosing on Cycle 1 
Day 1. The Investigator will maintain a screening and enrollment log to record details of all 
patients screened and to confirm eligibility or record reasons for screening failure, as applicable.  
The COVID-19 pandemic has impacted the conduct of this study, including travel restrictions 
and confinements of the trial participants and trial staff to perform study assessments. Several 
measures have been implemented by ERYTECH, and are reflected on trial assessments as 
described further below in the respective sections. 
7.1 
SCREENING ASSESSMENTS AND PROCEDURES 
All patients must sign and date an Institutional Review Board (IRB)/Independent Ethics 
Committee (IEC)-approved Informed Consent Form (ICF) prior to any screening assessments. 
However, an evaluation conducted as part of the patient’s routine clinical management (e.g., 
blood counts, disease evaluation) that is performed before signature of the ICF may be utilized 
for screening or baseline purposes provided that the procedure met the protocol-specified criteria 
and was performed within the time frame defined in the SOE (Table 1). Separate informed 
consent for the optional PGx assessment will be requested at the same time. 
For further information on the informed consent process, please refer to Section 9.1.1. 
Eligibility criteria are to be evaluated within 3 weeks prior to randomization, with confirmation 
that the patient continues to meet eligibility pre-dose on Cycle 1 Day 1. 
NOTE: Screening period longer than 3 weeks may be allowed due to COVID-19 related 
restrictions  
Screening Assessments to Be Completed within 3 Weeks prior to Randomization 
• Demography, including gender and date of birth. 
• Medical history, including cancer history and prior anticancer therapies. 
• Complete physical exam, including height and weight (height to be collected at screening 
only). 
• Vital signs: temperature, heart rate, and blood pressure. 
• ECOG PS, and KPS if ECOG PS is 1 (see APPENDIX 2 and APPENDIX 3). 
• Laboratory assessments (to be completed within 14 days of randomization): hematology, 
clinical chemistry, and coagulation panels will be completed at the local laboratory for 
the parameters defined in Table 10 below. All laboratory results must be documented in 
the eCRF. Additionally, reference ranges must be provided to the sponsor or its designee.

Page 81 of 119 
NOTE:  Please see Table 12 in Section 7.8.3 for Minimum Safety Labs required during 
COVID-19. 
• Serum pregnancy test (for patients of childbearing potential): a negative human chorionic 
gonadotropin test is required before the patient may receive any chemotherapy agent or 
eryaspase. 
• NOTE: A woman is considered of childbearing potential unless post-menopausal or 
permanently sterile by one of following methods: hysterectomy, bilateral salpingectomy 
and bilateral oophorectomy. A woman is considered postmenopausal in she has not had 
menses for 12 months without an alternative medical cause. 
• Collection of a paraffin-embedded tumor tissue block, or a minimum of 10 unstained 
slides, obtained from an archived or newly obtained tumor tissue sample for biomarker 
analysis. 
• Whole blood sample for PGx assessment (optional) 
• 12-lead ECG. 
• Baseline disease assessments: 
− Radiological imaging studies: 
o Chest CT scans. 
o Abdomen CT scans. 
o Brain MRI is indicated in patients with known/suspected brain metastasis at study 
entry. Brain scans will be repeated during the study at 12-week intervals if 
clinically indicated. 
o Bone scan is indicated in patients with known/suspected bone metastasis at study 
entry. Bone scans will be repeated during the study at 12-week intervals if 
clinically indicated. 
• Additional imaging as clinically indicated. 
− In general, CT scans are the preferred method of radiological assessment of the chest 
and abdomen; however, other techniques may be used (i.e., MRI). 
o The same imaging technique must be used for a given patient throughout the 
study. 
o Radiological images must be collected in a de-identified manner, quality 
controlled, stored, and available for future review and reading as necessary. 
• Prior and concomitant medications: record all medications the patient has received from 
14 days prior to randomization, as well as any and all prior therapies for the treatment of 
pancreatic cancer (or cancer-related events such as bone pain), and any currently ongoing 
medications. 
• Collection of AEs and SAEs from the date of informed consent.

TREATMENT PHASE ASSESSMENTS AND PROCEDURES 
7.3.1 
Assessments prior to Initiation of Treatment on Cycle 1 Day 1 
The following assessments will be performed on Cycle 1 Day 1 prior to initiation of study 
treatment. Screening laboratory tests and procedures may be substituted for those on Cycle 1 
Day 1 if performed within 5 days prior to Cycle 1 Day 1. 
• Symptom-directed physical examination, including body weight. 
• Vital signs: temperature, heart rate, and blood pressure. 
• ECOG PS, and KPS if ECOG PS is 1 (see APPENDIX 2 and APPENDIX 3). 
• EORTC QLQ-C30. 
• Hematology, clinical chemistry, and coagulation panels and CA19-9, Table 10. 
• Urine pregnancy test for patients of childbearing potential. A negative test is required 
before administration of any chemotherapy agent or eryaspase. 
• Baseline blood and plasma samples for pharmacokinetic and pharmacodynamic analysis 
(for patients in the eryaspase arm). 
• Baseline blood samples for immunogenicity (for patients in the eryaspase arm). 
• Baseline blood and plasma samples for biomarker analysis (both arms), such as ctDNA, 
proteomics, and transcriptomics. 
Prior to administration of the first infusion of eryaspase, (and each subsequent infusion during 
the treatment period), an IAST and complete compatibility (cross-match) test between the

patient’s blood and eryaspase should be performed using the removable segment tubes to 
confirm compatibility. In case a patient receives multiple bags of eryaspase to achieve the 
intended prescribed dose, a separate cross-match test must be performed with each eryaspase bag 
to confirm compatibility. In case of incompatibility, an additional blood sample may be required 
for further investigations. Details of collection and shipment are provided in the IMP Manual. 
7.3.2 
Efficacy Assessments During the Treatment Phase 
7.3.2.1 
RADIOLOGICAL DISEASE ASSESSMENTS 
CT/MRI of the chest and abdomen will be performed every 8 weeks (±3 days) calculated from 
the date of randomization until disease progression, patient’s withdrawal from study, or death. 
Every effort should be made to adhere to the assessment schedule, irrespective of any 
treatment delays or modifications. The same imaging technique must be utilized for a given 
patient throughout the study. 
Bone and/or brain scans are to be repeated every 12 weeks if clinically indicated. 
7.3.2.2 
HEALTH OUTCOMES 
Patient-reported outcomes will be measured using a standardized instrument, the EORTC 
QLQ-C30. The self-administered questionnaires will be completed every 4 weeks during the 
treatment phase. 
7.3.2.3 
PHARMACOKINETIC AND PHARMACODYNAMIC ASSESSMENTS 
For patients in the eryaspase arm, blood/plasma samples for pharmacokinetic and 
pharmacodynamic assessment will be collected, where possible, at the following time points of 
Cycles 1 and 3: 
• Day 1 prior to eryaspase administration, 
• Day 1 at 5-10 minutes post- eryaspase infusion, 
• At 5-8 days post-infusion (at the Investigator’s discretion), and 
• At Day 15 pre-dose. 
Samples will be analyzed for whole blood and plasma concentrations of ASNase and amino 
acids. The sparse PK data will be combined with previous data as part of a Population PK 
(POP PK) analysis. To this effect, sample collection for PK and pharmacodynamics may be 
stopped based on the outcome of the evaluation of sample results during the course of the trial. 
The date and clock time for collection of each blood sample and for sample processing (e.g., 
time placed on ice, time of centrifugation, etc.) will be documented. Further details will be 
provided in the lab manual. 
7.3.2.4 
IMMUNOGENICITY 
For patients in the eryaspase arm, samples for assessment of anti-ASNase antibodies and 
neutralizing antibodies will be collected pre-dose at Cycle 1 Day 1, and Day 15 and at Day 1 of 
every second cycle thereafter (i.e., at Cycle 3 Day 1, Cycle 5 Day 1, and so on), and upon 
determination of disease progression, and EOT, whichever is sooner.

BIOMARKER ASSESSMENTS 
Plasma Samples 
Plasma samples for biomarker analysis will be collected pre-dose on Cycle 1 Day 1 and Day 15 
and at Day 1 of every second cycle thereafter (i.e., at Cycle 3 Day 1, Cycle 5 Day 1, and so on), 
upon determination of disease progression, and EOT, whichever is sooner. 
Pharmacogenetic Sample 
An optional blood sample for pharmacogenetic (PGx) analysis will be obtained once during the 
study, preferably during the screening phase. A separate informed consent must be signed before 
the sample is obtained. 
7.3.3 
Safety Assessments during the Treatment Phase 
The following safety assessments will be performed pre-dose for all patients on Day 1, and 
Day 15, unless otherwise specified. 
• Hematology, clinical chemistry, and coagulation panels and CA19-9. 
• For patients under eryaspase arm, in addition to regular evaluation of liver function tests 
before treatment administration, patients will be monitored on weekly basis in the event 
of occurrence of ≥Grade 2 elevation of liver enzymes and bilirubin levels. 
• For women of childbearing potential, additional pregnancy testing should be performed 
in case of delayed menstrual period and is recommended to be performed monthly and 
until the end of treatment exposure extended by 30 days, in case of sexual activity.  
• Vital signs: temperature, heart rate, and blood pressure. 
• Symptom-directed physical examination, including body weight. 
• ECOG PS (see APPENDIX 2). 
• 12-lead ECG: as clinically indicated. 
• Collection of AEs: from time of informed consent until 90 days after the last study 
treatment or start of new anti-cancer treatment, whichever is sooner. 
• Review/recording of all concomitant medications added and/or changed from 14 days 
prior to randomization until 90 days after the last study treatment or start of new 
anti-cancer treatment, whichever is sooner. 
7.4 
END OF TREATMENT VISIT 
The End of Treatment (EOT) visit should be conducted as soon as possible (but no later than 
30 days) after the patient’s discontinuation of the study drug, and will include the following 
assessments: 
• Hematology, clinical chemistry, and coagulation panels and CA19-9. 
• Serum pregnancy test for patients of childbearing potential. 
• Vital signs: temperature, heart rate, and BP. 
• Symptom-directed physical exam, including body weight. 
• ECOG PS (see APPENDIX 2).

• Samples for immunogenicity (for patients in the eryaspase arm) and biomarker analysis 
(both arms). 
7.5 
FOLLOW-UP PHASE ASSESSMENTS AND PROCEDURES 
During the follow-up phase, the extent of efficacy evaluation will depend on the disease status: 
• In the absence of disease progression or starting new anti-cancer therapy 
− Radiological imaging of Tumor lesions to be carried out every 8 weeks until disease 
progression, 
− And then OS follow up every 8 weeks until death, lost for follow up or withdrawal 
from study 
• In the presence of objective disease progression or start of anticancer therapy 
−  OS follow up every 8 weeks until death, lost for follow up or withdrawal from study. 
 
Collection and follow-up of AEs and SAEs will occur until 90 days after discontinuation of the 
study drug, beginning of a new cancer treatment, or death, whichever occurs first. SAEs will be 
followed until resolution. 
For all patients who discontinue study treatment, the EORTC QLQ-C30 questionnaire will be 
completed every 8 weeks during the follow-up phase until withdrawal from the study or death. 
7.5.1 
Post-Study Subsequent Cancer Therapy 
Information will be collected about any subsequent cancer therapy given after discontinuation of 
study drug (s), including both medications and procedures. 
7.5.2 
Survival Follow-Up 
Survival information will be collected by phone, follow-up visit, or from medical records 
approximately every 8 weeks from the date of the EOT visit until the patient’s death, until the 
patient is lost to follow-up, or until study closure. Survival follow-up will include collection of 
information about any subsequent anticancer therapy received after discontinuation of study 
drug. 
If a patient fails to return for scheduled visits or is unreachable for survival follow-up, the 
following efforts should be made to contact him/her: 3 phone attempts, including the date and 
time, should be documented in the patient’s chart. If there is no response to the phone calls, a 
certified letter or local equivalent should be sent. After these efforts have been exhausted with no 
response, a patient should be considered as lost to follow-up. 
7.6 
EFFICACY ASSESSMENTS 
7.6.1 
Radiological Disease Assessment and Evaluation of Response 
CT/MRI scans of the chest and abdomen will be performed every 8 weeks, calculated from the 
date of randomization, until disease progression, or until withdrawal from the study, or death.

Every effort should be made to adhere to the assessment schedule. The same imaging 
technique must be utilized for a given patient throughout the study. 
Tumor response and disease progression will be evaluated in this study using a modified version 
of the criteria proposed by the RECIST Committee, version 1.1 (RECIST 1.1). The 
modifications to RECIST 1.1 will be used to more accurately and consistently assess responses 
in specific cases that are not addressed in RECIST 1.1. These modifications are indicated 
below in italics. 
7.6.1.1 
KEY DEFINITIONS 
7.6.1.1.1 
MEASURABLE DISEASE 
• Measurable non-nodal lesions: those that can be accurately measured in at least 1 
dimension, longest diameter (LD) to be recorded as ≥10 mm by CT scan (CT slice 
thickness no greater than 5 mm). 
• Malignant lymph nodes: to be considered pathologically enlarged and measurable, a 
lymph node must measure ≥15 mm in the short axis (SA) when assessed by CT scan (CT 
slice thickness recommended to be no greater than 5 mm). 
• It is recommended that slice gaps not be utilized for the image acquisition procedures. 
• All radiographic measurements should be taken and recorded in millimeters utilizing an 
electronic measurement method based on lesion boundary definition. 
• Lesions on chest X-ray will not be considered measurable. 
7.6.1.1.2 
NON-MEASURABLE DISEASE 
• All other lesions (or sites of disease), including small lesions (LD <10 mm or 
pathological lymph nodes ≥10 mm to <15 mm in the SA) as well as truly non-measurable 
lesions, are considered non-measurable disease. Lesions considered truly non-measurable 
include leptomeningeal disease, ascites, pleural or pericardial effusions, inflammatory 
breast disease, lymphangitic involvement of skin or lung, and masses or abdominal 
organomegaly identified by physical exam that are not measurable by reproducible 
imaging techniques. 
7.6.1.1.3 
TARGET LESIONS 
• Target lesions must be measurable lesions. 
• All lesions up to a maximum of 5 lesions per organ and 10 lesions in total, 
representative of all involved organs, will be identified as target lesions, recorded and 
measured at baseline, and followed consistently throughout the study. 
• Target lesions should be selected on the basis of their size (based on LD for non-nodal 
lesions or SA for lymph nodes), their suitability for accurate repeated measurements, and 
on their being most representative of the patient’s tumor burden. 
• A sum of the diameters for all target lesions will be calculated and reported for each time 
point. The baseline sum of diameters will be used as a reference according to which the 
objective tumor response will be characterized.

CONFIDENTIAL AND PROPRIETARY 
 
Page 88 of 119 
7.6.1.1.4 
NON-TARGET LESIONS 
• All other lesions (or sites of disease, including any measurable lesions that were not 
selected as target lesions) will be identified as non-target lesions and indicated as present 
at baseline. 
• It is possible to record multiple non-target lesions involving the same organ as a single 
item (e.g., multiple enlarged pelvic lymph nodes or multiple liver metastases). 
• Measurements of these non-target lesions will not be performed, but the presence, 
absence, or unequivocal progression of these lesions should be noted for subsequent 
assessments. 
7.6.1.1.5 
NEW LESIONS 
• A separate assessment category of “new lesions” is defined as part of the independent 
reading. 
• The finding of a new lesion should be unequivocal (i.e., not attributable to differences in 
scanning technique, change in imaging modality, etc.). 
• If a new lesion is equivocal (i.e., because of its small size), and follow-up imaging 
confirms that it is definitely a new lesion, then the lesion will be considered to have 
appeared on the date of the initial scan, indicating disease progression as of that date.  
• A lesion identified on a follow-up scan in an anatomical location that was not scanned at 
baseline is considered a new lesion and will indicate disease progression. 
• A lesion that reappears at follow-up after a response of PR or stable disease is not 
considered new. The lesion’s LD (or SA for lymph nodes) is added back into the sum of 
diameters. 
• A lesion that reappears at follow-up after a CR is automatically considered PD. 
7.6.1.1.6 
LYMPH NODES 
• At baseline, lymph nodes with tumor burden will be considered target lesions if the SA is 
≥15 mm. 
• At baseline, lymph nodes will be considered non-target lesions if the SA is ≥10 mm and 
<15 mm. 
• At baseline, lymph nodes will be considered normal if the SA is <10 mm. 
• At subsequent assessments, a lymph node must measure ≥10 mm along the SA to be 
considered a new lesion. 
• A lymph node that was identified as a target lesion at baseline that falls below the 
measurable threshold at subsequent assessment and then gets larger is not considered 
new if it follows a PR or SD. The lymph node SA measurement is added back into the 
sum of diameters. 
• A lymph node that was identified as a target lesion at baseline that falls below the 
measurable threshold at subsequent assessment and then gets larger following a CR is 
automatically considered PD.

7.6.1.2 
OTHER CONSIDERATIONS 
7.6.1.2.1 
IRRADIATED LESIONS 
Previously irradiated lesions cannot be selected as target lesions. These lesions can be monitored 
to assess progression as non-target lesions. 
7.6.1.2.2 
HANDLING OF LESIONS THAT SPLIT 
When non-nodal and nodal lesions split or fragment, the individual diameters of the fragmented 
portions should be added together to calculate the target lesion sum. 
7.6.1.2.3 
HANDLING OF LESIONS THAT MERGE 
As lesions merge, a boundary between the lesions should be drawn so the LD or SA of each 
individual lesion can continue to be measured. If the lesions have merged in such a way that they 
can no longer be separated by this boundary, the LD or SA of the merged lesion should be 
measured. 
7.6.1.3 
MEASUREMENT OF SMALL LESIONS ON FOLLOW-UP SCANS 
7.6.1.3.1 
NON-NODAL LESIONS 
A non-nodal target lesion that is present but too small to measure accurately at evaluations after 
baseline (<5 mm but greater than 0 mm in unilateral dimension) will be classified as Too small 
to measure and will be assigned a value of 5 mm for the purposes of determining the sum of 
diameters. All other lesions (i.e., ≥5 mm) will have actual size recorded. 
7.6.1.3.2 
LYMPH NODES 
A target lymph node should always have the actual SA measurement recorded, even if the lymph 
node regresses to <10 mm on study. This means that when lymph nodes are included as target 
lesions, the sum of diameters may not be zero even if CR criteria are met, since a normal lymph 
node is defined as having an SA of <10 mm. 
7.6.1.4 
RESPONSE CRITERIA 
7.6.1.4.1 
TARGET LESION RESPONSE CRITERIA 
• Complete response (CR): Disappearance (or normalization) of all target lesions. 
− Any pathological lymph nodes (whether target or non-target) must have reduction in 
SA to <10 mm.  
• Partial response (PR): At least 30% decrease in the sum of diameters of target lesions, 
taking as reference the baseline sum of diameters.  
• Stable disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase 
to qualify for PD, taking as reference the smallest sum of diameters while on study. 
• Progressive disease (PD): At least a 20% increase in the sum of diameters of target 
lesions, taking as reference the smallest sum of diameters on study (this includes the 
baseline sum if that is the smallest on study). In addition to the relative increase of 20%, 
the sum must also demonstrate an absolute increase of at least 5 mm.

Page 90 of 119 
• Non-evaluable (NE): Patient time points that have inadequate or missing images, 
including the inability to visualize >25% of target disease. 
7.6.1.4.2 
NON-TARGET LESION RESPONSE CRITERIA 
• CR: Disappearance (or normalization) of all non-target lesions.  
• All lymph nodes must be non-pathological in size (<10 mm SA). 
• Non-complete response, non-progressive disease (Non-CR/Non-PD): Persistence of 1 or 
more non-target lesion(s). 
• PD: Unequivocal progression of existing non-target lesions. 
• NE: Patient time points that have inadequate or missing images, including the inability to 
visualize >50% of non-target disease. 
• No disease (ND): No non-target disease noted. The absence of non-target lesions at 
follow-up time points is designated as ND and not SD when there is no non-target 
disease noted at baseline. 
7.6.1.4.3 
NEW LESION RESPONSE CRITERIA 
A separate assessment of the appearance of one or more new lesions will be provided in the read. 
If at least one new lesion is present, the patient is considered to have progressive disease overall. 
7.6.1.4.4 
RESPONSE ASSESSMENT IN CASE OF MISSING OR 
TECHNICALLY INADEQUATE SCANS 
If no lesions were identified at baseline in a specific body region (e.g., chest or abdomen) and the 
scan of that body region is unavailable at follow-up, then the response assessment will be based 
on the scans of the other regions. 
7.6.1.5 
DETERMINATION OF RADIOLOGICAL BEST OVERALL RESPONSE 
Best overall response (BOR) is the best response recorded from the start of treatment until the 
end of treatment (taking as reference for PD the smallest measurement recorded since the start of 
treatment). 
7.6.2 
Health Outcomes 
Patient-reported outcomes will be measured using a standardized instrument, the EORTC 
QLQ-C30, at the following time points: 
• Cycle 1 Day 1 before treatment. 
• Every 4 weeks during the treatment phase, Day 1 of each cycle before treatment. 
• At the End of Treatment visit. 
• Every 8 weeks during the follow-up phase until end of study. 
The following scores will be calculated: 5 functional scales, 3 symptom scales, a global health 
status/quality of life (QoL) scale, and 6 single items (Table 11).

Pharmacokinetic and Pharmacodynamic Assessments 
Eryaspase pharmacokinetics will be evaluated using sparse sampling, where possible. Whole 
blood and plasma concentrations of ASNase from these samples will be combined with previous 
data as part of a POP-PK analysis. The pharmacodynamic effect of eryaspase on amino acid 
levels will also be evaluated. 
For all patients who provide samples, PK and pharmacodynamics of eryaspase will be assessed 
at each measurement in terms of: 
• Total ASNase activity (U/L), 
• Plasma ASNase activity (U/L), 
• Plasma concentrations of asparagine (µmol/L), and

• Plasma concentrations of glutamine (µmol/L). 
See Section 7.8.5 for information related to the discontinuation of PD sample collection due to 
COVID-19  
7.6.4 
Immunogenicity 
The development of anti-ASNase antibodies and neutralizing antibodies will be determined for 
patients in the eryaspase arm. 
7.6.5 
Biomarker Assessments 
This study will collect samples for biomarker assessments in all patients. Sample types collected 
include tumor samples, whole blood samples and plasma samples. Biomarkers will be tested 
prospectively and summarized at baseline and, where applicable, at subsequent assessments. 
These assays will be performed at central laboratories. In addition, biomarkers identified in other 
clinical studies may also be assessed in the biomarker samples collected from patients enrolled in 
this study. Detailed instructions for processing, storage, and shipping of samples will be provided 
in the Laboratory Manual  
7.6.5.1 
ANALYSIS OF TUMOR TISSUES 
A paraffin-embedded tissue block (FFPE), or a minimum of 10 unstained slides, obtained from 
an archived or newly obtained tumor tissue sample (primary tumor or metastatic lesion) will be 
required.  
All tumor samples may be used to assess the effects of eryaspase and tumor-relevant pathway 
dysregulation (such as mutations, amplifications) that may be important in the development of 
progression of cancer as well as for the potential use in diagnostic development. Assays to 
evaluate biomarkers that may correlate with clinical outcome may be performed at central 
laboratories, such as: 
• Mutational analyses and detection of gene amplification of relevant oncogenes (e.g., 
KRAS, MYC, PI3KCA, and FGFR) and genes involved in activated pathways of survival 
and proliferation (e.g., Erk1/2, STAT3, AKT, and MAPK). 
• Expression profiling may be done by analysis of ribonucleic acid (RNA) extracted from 
tissue. 
• Depending on tissue availability, additional assays including immunohistochemistry 
(IHC), gene expression profiling, or protein activation may be performed. 
• If applicable, mechanisms of resistance to eryaspase treatment will be evaluated. 
 
 
7.6.5.2 
ANALYSIS OF PLASMA SAMPLES 
Plasma samples will be collected for the following biomarker analyses: 
• Circulating tumor DNA (ctDNA) may be analyzed in plasma samples to identify 
plasma-borne somatic mutations as predictors of clinical outcome with eryaspase. 
• Proteomic and transcriptomic analyses of biomarker samples may be conducted to 
identify profiles that can be related to treatment response. Examination of pre- and

Page 93 of 119 
post-treatment protein and transcript profiles may uncover novel blood-borne candidate 
biomarkers/profiles that could be used to predict response to eryaspase. 
• Markers of immunological response may be evaluated for correlation with response. 
7.6.5.3 
PHARMACOGENETIC ANALYSIS 
Pharmacogenetic analysis is the study of the variability in drug response due to hereditary 
factors. Individual genetic composition (genotype) may have an impact on the PK and the 
pharmacodynamic effects of the drug. Examples of pharmacogenetic analyses include 
genotyping of metabolizing enzymes such as uridine 5'-diphosphate glucuronosyltransferases 
(UGTs) and transports, evaluation of a whole-genome single nucleotide polymorphism (SNP), or 
other genetic marker sets. The information obtained is solely used to further characterize drug 
effects and does not have clinical, diagnostic, or therapeutic implications for the individual 
patients. This PGx research is not designed to determine whether other members of the patient’s 
family are at risk of developing pancreatic cancer. The Sponsor will be blinded as to the 
subject’s identity and since the analysis is done for research purposes only, individual results will 
not be shared with the Investigator and/or subject or the subject’s relatives. Any information 
obtained is not intended for inclusion in the medical record. This research will not change the 
care the subject receives in this study. 
A whole blood sample (5 mL) will be drawn using a tube containing ethylenediaminetetraacetic 
acid (EDTA) from patients who provide separate written informed consent for this optional 
procedure. Patient participation in the PGx analysis is voluntary, and refusal of consent will not 
disqualify the patient from participating in the study. Furthermore, a patient can withdraw 
consent for the PGx analysis at any time during the study. 
7.6.5.4 
SAMPLE COLLECTION, STORAGE, AND SHIPPING 
Detailed procedures for collection, processing, handling, storage, and shipment of samples for 
central laboratory analysis (PK, pharmacodynamics, immunogenicity, biomarkers, and PGx) will 
be provided in the Laboratory Manual. 
7.6.5.5 
BIOANALYSIS 
Samples will be analyzed using validated, where applicable, analytical methods. A description of 
the assays and validation data will be provided in separate analytical reports. 
7.6.5.6 
STORAGE OF BIOLOGICAL SAMPLES FOR POTENTIAL FUTURE 
ANALYSIS 
After the end of the study, biological samples or derivatives (such as DNA, RNA, and protein) 
will be stored at a central repository for the maximum number of years defined per local 
regulatory requirements to allow scientific research to be conducted in the future as new 
discoveries are made.

7.7 
ADVERSE EVENTS AND SERIOUS ADVERSE EVENTS 
The Investigator is required to report to the Sponsor or its representative all AEs occurring 
during the clinical study (Title 21 Code of Federal Regulations [CFR] Part 312.64[b] and 
International Council for Harmonization [ICH] E6 [R2]).  
7.7.1 
Definition of Adverse Events 
An adverse event (AE) is any untoward medical occurrence in a patient or clinical trial subject 
administered a medicinal product and which does not necessarily have a causal relationship with 
this treatment. An AE can therefore be any unfavorable and unintended sign (including an 
abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated 
with the use of a medicinal product, whether or not considered related to the medicinal product. 
7.7.2 
Definition of Serious Adverse Events 
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 
1. Results in death, 
2. Is life-threatening, 
3. Requires inpatient hospitalization or prolongation of existing hospitalization, 
4. Results in persistent or significant disability/incapacity, 
5. Is a congenital anomaly/birth defect, or 
6. Is otherwise medically significant (any event not meeting the above criteria that, based 
upon medical judgment, jeopardizes the patient, and may require medical or surgical 
intervention to prevent one of the other outcomes listed in the definition of an SAE). 
NOTE: If the standard of care or institutional practice requires hospitalization of patients for the 
sole purpose of conducting study procedures or delivering study therapy, then such hospital 
admission will not be considered or reported as meeting SAE criteria. However, should an SAE 
develop during such a hospitalization, it will be considered serious and reported as such. 
NOTE: Disease progression should not be reported as an SAE for the purposes of this study. 
NOTE: in instances, where an adverse event changes to serious event; this date should be the 
onset date of the SAE. 
7.7.3 
Classification of Adverse Events 
7.7.3.1 
SEVERITY GRADING 
The severity of AEs is to be graded according to the National Cancer Institute Common 
Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0. For AEs not listed in the 
CTCAE scale, the following definitions should be used: 
• Mild (Grade 1): The AE is noticeable to the patient but does not disrupt normal daily 
activities; it does not require discontinuation of the study drug, but may require additional 
therapy. 

ERYTECH Pharma 
Amended Protocol GRASPANC 2018-01 
Investigational Product: Eryaspase 
Version 2.0 (14th December 2020) 
CONFIDENTIAL AND PROPRIETARY 
 
Page 95 of 119 
• Moderate (Grade 2): The AE is moderately uncomfortable and interferes with the 
patient’s daily activities; it does not require discontinuation of the study drug but may 
require additional therapy. 
• Severe (Grade 3): The AE is intolerable and disrupts normal daily activities, and may 
require additional therapy or hospitalization and/or discontinuation of the study drug. 
• Life-threatening (Grade 4): The AE exposes the patient to risk of death at the time of 
the event; this does not refer to an event that might have caused death if it had been more 
severe. Any event which is considered life-threatening is considered to be serious, and 
must be reported as described in Section 7.7.6. 
• Death related to AE (Grade 5): An event that results in death is considered a Grade 5 
AE, and by definition, is an SAE. Any event with a fatal outcome must be reported as 
described in Section 7.7.6. 
7.7.3.2 
CAUSALITY ASSESSMENT 
An Investigator who is qualified in medicine must assess the causal relationship between 
eryaspase, chemotherapy, or both and each occurrence of each AE/SAE. The Investigator should 
decide whether, in his/her medical judgment, there is a “reasonable possibility” that the event 
may have been caused by the study drug (IMP and non-IMP background treatment). 
• If no valid reason exists for suggesting a causal relationship between the study drug (IMP 
or non-IMP background treatment) and the occurrence of the AE, then the AE should be 
classified as “unrelated.” 
• If there is any valid reason for suspecting a possible causal relationship between the study 
drug (IMP and non-IMP background treatment) and the occurrence of the AE, then the 
AE should be considered “related.” 
Alternative causes, such as underlying disease(s), concomitant therapy, and other risk factors, as 
well as the temporal relationship of the event to study treatment administration, should be 
considered and investigated. The Investigator should also consult the IB in making his/her 
assessment. 
There may be situations in which an SAE has occurred and the Investigator has minimal 
information to include in the initial report to the Sponsor. However, it is critical that the 
Investigator provide an assessment of causal relationship for every event before the initial 
transmission of the SAE report to the Sponsor, as it is one of the criteria used when determining 
regulatory reporting requirements. 
The Investigator may change his/her opinion of causality in light of follow-up information; in 
this case an SAE follow-up report should be sent with the updated causal relationship 
assessment. 
Definitions of the causal relationship of an AE to the use of the study medication are as follows: 
• Related: There is a reasonable possibility of a causal relationship between the 
administration of the study drug (IMP and non-IMP background treatment) and the 
adverse event emergence. “Reasonable possibility” means there is evidence to suggest a 
causal relationship, e.g. temporal relationship, biological plausibility, between study 
intervention and the AE.

Page 96 of 119 
• Not Related: There is no reasonable possibility that the administration of the study 
intervention caused the event, there is no temporal relationship between the study 
intervention and the event onset, or an alternate etiology has been established. 
7.7.3.3 
EXPECTEDNESS 
The drug safety group will be responsible for determining whether an AE is expected or 
unexpected, based on available reference safety information in the IB. An AE will be considered 
unexpected if its nature, severity, or frequency is not consistent with the reference safety 
information described for eryaspase in the IB. 
7.7.4 
Time Period and Frequency for Adverse Event Assessment and Follow-Up 
All AEs that are reported by a patient or observed by study personnel from the date of patient 
informed consent until 90 days after the last study treatment or start of new anti-cancer 
treatment, whichever is sooner, will be reported. 
Any medical condition that is present at the time that the patient is screened will be considered as 
a baseline condition and not reported as an AE.  
All AEs must be followed until they resolve, return to baseline, or are determined to be 
permanent at the EOT visit. 
7.7.5 
Recording Adverse Events and Serious Adverse Events 
All AEs, whether serious or non-serious, must be recorded in the source documents and in the 
eCRF using standard medical terminology. For each event, the Investigator will evaluate and 
report the onset date, resolution date, severity, causality, action taken, seriousness, outcome (if 
applicable), and whether or not it caused any change in study drug administration (dose delay, 
dose reduction, or study treatment discontinuation). Changes in the severity of an AE must be 
documented to allow the duration of the event at each level of severity to be assessed. AEs 
characterized as intermittent require documentation of the onset and duration of each episode. 
Whenever possible, diagnoses should be provided when signs and symptoms represent a 
common etiology (e.g., cough, runny nose, sneezing, sore throat, and head congestion should be 
reported as “upper respiratory infection”). A specific disease or syndrome, rather than individual 
associated signs and symptoms, should be identified whenever possible. Where there is no link 
between different clinical symptoms occurring at the same time, each sign should be recorded as 
a separate AE. All reported information must be in English. 
When an AE occurs, it is the Investigator’s responsibility to review all documentation related to 
the event (e.g., hospital progress notes, laboratory and diagnostics reports). The Investigator will 
then record all relevant AE information in the eCRF. It is not acceptable for the Investigator to 
send photocopies of the patient’s medical records to the Sponsor in lieu of completion of the 
eCRF AE pages. 
In some instances, the Sponsor may request copies of medical records for certain patients. 
Should this occur, all patient identifiers, with the exception of the patient’s study identification 
number, will be redacted on the copies of the medical records before submission to the Sponsor.

Serious Adverse Event Reporting 
7.7.6.1 
INVESTIGATOR REPORTING RESPONSIBILITIES FOR SERIOUS 
ADVERSE EVENTS 
If an AE meets the definition of “serious,” the Investigator must report it immediately (within a 
maximum of 24 hours from knowledge of the event), regardless of its presumed relationship to 
the IMP. To do so, the Investigator must complete the SAE Form, and forward it to 
PrimeVigilance, mandated by ERYTECH Pharma, at: 
Email: erytechpv@primevigilance.com 
eFax (US): +1(0) 8006470631  
eFax (EU): +44(0) 8000669250 
All reported information must be submitted in English. It is not acceptable for the Investigator to 
send photocopies of the patient’s medical records to the Sponsor in lieu of completion of the 
SAE form. 
If necessary, the Investigator will be asked for additional information which may include hospital 
records, laboratory reports, or other test results. 
SAEs must be followed until they resolve, or are determined to be permanent at the EOT visit, or 
until the patient dies or is lost to follow-up. The Investigator must forward any relevant 
follow-up information for SAEs (including outcome and diagnosis) in the same manner as the 
initial report within 24 hours of obtaining the information. 
7.7.6.2 
EXPEDITED REPORTING AND INVESTIGATOR SAFETY REPORTS 
The Sponsor is responsible for submitting all suspected unexpected serious adverse reactions 
(SUSARs) related to the IMP to Competent Authorities (and IECs/IRBs as required) and to 
Investigators in accordance with ICH Guidelines and/or local regulatory requirements, as 
applicable. 
It is the Investigator’s responsibility to notify the local IEC/IRB of all suspected unexpected 
serious adverse reactions or other specific safety information (e.g., summary or listing of SAEs) 
involving risk to human subjects as appropriate according to local requirements. 
The Investigator will acknowledge and file all safety updates received from the sponsor along 
with the IB in the Investigator’s Site File. 
7.7.7 
Events of Special Interest 
The following events are considered events of special interest: 
• Venous thrombotic events, 
• Hepatic toxicity, 
• Pancreatitis, and 
• Transfusion-related events.

7.7.8 
Reporting of Pregnancy 
If a female patient or the partner of a male patient becomes pregnant, the patient must inform the 
Investigator immediately. The Investigator must immediately report any pregnancy occurring 
during the trial to ERYTECH Pharma by completing the “Exposure during pregnancy case report 
form” and forward it to PrimeVigilance, mandated by ERYTECH Pharma, at: 
Email: erytechpv@primevigilance.com 
eFax (US): +1(0) 8006470631  
eFax (EU): +44(0) 8000669250 
Patients will give consent upon enrollment for this reporting of any pregnancy during the trial as 
well as information about the delivery and about the baby’s health until the age of 6 month. 
Pregnancy complications must be recorded as AEs. If the infant has a congenital anomaly/birth 
defect, this must be reported and followed as an SAE. 
 
7.8 
CHANGES IN PROTOCOL DUE TO COVID-19  
7.8.1 
BACKGROUND 
There is currently an outbreak of respiratory disease caused by a novel coronavirus. The virus 
has been named “SARS-CoV-2” and the disease it causes has been named “Coronavirus Disease 
2019” (COVID-19). On January 31, 2020, Health and Human Services (HHS) issued a 
declaration of a public health emergency related to COVID-19 and mobilized the Operating 
Divisions of HHS. 
The COVID-19 worldwide pandemic has the potential to impact the conduct of clinical trials and 
challenges may arise due to issues such as quarantines, site closures, travel limitations, or 
interruptions to the supply chain of investigational products.  These challenges may lead to 
difficulties in meeting protocol-specified procedures, including administering or the use of 
investigational products or adhering to protocol-mandated visits and laboratory/diagnostic 
testing.   
Regulatory authorities in the EU and the US have provided guidance on how to handle the 
potential impacts of the COVID-19 pandemic when conducting clinical studies.  In the US, the 
Food and Drug Administration (FDA) published “FDA Guidance on Conduct of Clinical Trials 
of Medical Products during the COVID-19 Public Health Emergency”, and in the EU, the 
European Medicines Agency (EMA) published  “Guidance on the Management of Clinical Trials 
during the COVID-19 (coronavirus) pandemic”. 
Erytech followed the guidance in these documents and conducted a Risk Assessment of the 
COVID-19 pandemic on the conduct of Trybeca-1 to ensure the safety of subjects seen during 
the COVID-19 pandemic and maintain data quality and integrity.

Investigators should make every attempt to maintain patient’s treatment administration as 
planned for each treatment arm per protocol and patient assessments as outlined in the Schedule 
of Events.  Given the need to quarantine, travel restrictions and site closures, patients may be 
evaluated outside of the protocol parameters, including having laboratory or radiological 
assessments performed at another location. 
Disease assessments, particularly CT/MRI scans should be performed every 8 weeks [+ 3 days] 
from randomization per protocol, when possible.  Local imaging centers should be used if 
possible.

7.8.6 
PROTOCOL DEVIATIONS 
 
Investigators will apply due diligence to avoid protocol deviations if possible.  All protocol 
deviations due to delayed or missed visits and protocol required assessments or treatments 
related to COVID-19 will be collected on the COVID-19 Related Deviation Log (APPENDIX 
4).  This log will serve as source documentation for entry into the COVID-19 eCRF form within 
the electronic data capture system. 
 
7.8.7 
CLINICAL MONITORING 
 
On-site monitoring visits may be converted to remote monitoring visits according to the 
Monitoring Plan if on-site visits cannot be conducted due to COVID-19 restrictions on site 
closures, limited access to study staff and travel restrictions.  Access to source documents 
(medical records) may be provided electronically or other secure method to comply with 
applicable privacy and security laws for the use and disclosure of information related to the 
research set forth in this protocol if authorized by national competent authorities.   
 
Remote monitoring visits will be converted back to on-site visits upon a site’s availability to 
reopen safety.

STATISTICAL CONSIDERATIONS 
8.1 
STATISTICAL HYPOTHESES 
The primary efficacy endpoint is Overall Survival (OS) and the study is designed to test the 
superiority of eryaspase plus chemotherapy over chemotherapy alone. The primary analysis will 
test the following hypotheses: 
• Null Hypothesis: The hazard ratio for OS between eryaspase plus chemotherapy and 
chemotherapy alone is equal to one 
• Alternative Hypothesis: The hazard ratio for OS between eryaspase plus chemotherapy 
and chemotherapy alone is less than one 
The key secondary efficacy endpoints are Progression-free Survival (PFS), Objective Response, 
Duration of Response (DoR) and Disease Control Rate (DCR). 
The null and alternative hypotheses for PFS will be as for OS 
The primary analyses of the endpoints objective response and disease control will test the 
following hypotheses: 
• Null Hypothesis: The Objective Response Rate (ORR)/Disease Control Rate (DCR) in 
the eryaspase plus chemotherapy group is equal to the Objective Response Rate 
(ORR)/Disease Control Rate (DCR) in the chemotherapy alone group 
• Alternative Hypothesis: The Objective Response Rate (ORR)/Disease Control Rate 
(DCR) is greater in the eryaspase plus chemotherapy group versus the chemotherapy 
alone group 
There will be no formal statistical testing for DoR as this is not a randomized comparison and 
these data will be evaluated through the presentation of descriptive statistics 
All statistical testing will be undertaken based on a one-sided 2½% significance level subject to 
adjustments for interim analysis. 
8.2 
SAMPLE SIZE DETERMINATION 
With a power of 88.4% and an overall one-sided type I error of 2.5%, and including one interim 
analysis for efficacy with an O’Brien-Fleming type stopping rule, a total of 390 deaths are 
required to detect a treatment effect hazard ratio of 0.725 for eryaspase plus chemotherapy 
versus chemotherapy alone. The hazard ratio in the Phase 2 study for eryaspase was 0.63 
(95% CI: 0.39 to 1.10), and 0.725 represents a conservative estimate based on these data that is 
viewed as being highly clinically relevant. 
The interim analysis for efficacy will take place once 261 (67%) events have been observed.  
Assuming a recruitment period of 26 months, a median overall survival in the control group of 
6.0 months, a 10% probability of dropping out during the course of the study, and a minimum 
follow-up of 9 months, the study size will be based on the recruitment of 482 patients.

ANALYSIS POPULATIONS 
Intent to Treat population (ITT): All patients randomized, irrespective of whether they 
received study medication. 
Safety population (SP): All randomized patients who receive at least one dose of study 
medication (eryaspase or chemotherapy). 
Per Protocol population (PP): The PP population is a subset of the ITT population, and consists 
of all randomized patients who meet the major inclusion criteria and none of the major exclusion 
criteria and who receive at least one cycle of treatment. The major inclusion/exclusion criteria 
that are to be considered here will be defined in the Statistical Analysis Plan (SAP). 
8.4 
STATISTICAL ANALYSES 
8.4.1 
Analysis of the Primary Efficacy Endpoint 
The primary endpoint is OS which is measured from the date of randomization to the date of 
death from any cause. Patients who are not known to have died will be censored at the date of 
last contact, and this will apply as of the date of data cut-off for any particular analysis. 
The primary analysis will be the comparison of OS between the two treatment arms in the ITT 
population using the one-sided stratified log-rank test, with stratification factors as used in the 
randomization. Data will be summarized in Kaplan-Meier curves together with medians and 
95% confidence intervals for those medians. The Cox Proportional Hazards model, stratified for 
the randomization factors, will be used to obtain a hazard ratio together with its 95% confidence 
interval. 
8.4.2 
Analysis of the Secondary Endpoints 
PFS will be compared between the two treatment arms using the same methods of analysis as for 
OS. 
The following efficacy analysis will also be performed in the ITT population: 
• ORR, defined as the proportion of patients who achieve objective tumor response (CR or 
PR) per RECIST 1.1. Each patient’s BOR will be summarized (CR, PR, SD, PD, or 
unknown). This comparison will be based on the Cochran-Mantel-Haenszel test, with 
stratification factors as for the analysis of OS and PFS. Results will be reported in terms 
of an odds ratio and associated 95% confidence interval. 
• DCR (disease control rate), defined as the proportion of patients who achieve CR, PR and 
SD, 
• DoR will be evaluated in patients who achieve CR/PR. It will be measured from the time 
CR/PR (whichever is first recorded) is first met until the first date that recurrence or PD 
is objectively documented. Kaplan-Meier curves will be provided in association with this 
analysis; however, there will be no p-value calculations, as this is not a randomized 
comparison.

Page 104 of 119 
• Extensive evaluation of the consistency of treatment effect for OS and PFS across the 
population as a whole will be undertaken by providing analyses in subgroups, with 
displays in forest plots and p-values for treatment by interactions. 
8.4.3 
Other Aspects of the Efficacy Analyses 
Additional disease control endpoints will be evaluated as exploratory analyses, namely DCR8, 
DCR12, and DCR16 defined as the disease control rates when SD is required to last for at least 
8 weeks, at least 12 weeks, and at least 16 weeks respectively. These analyses will follow the 
methodology for DCR outlined in Section 8.4.2. 
All primary and secondary efficacy analyses will be repeated in the PP population. 
Confirmatory testing for the primary and secondary efficacy endpoints will be performed 
hierarchically (OS followed by PFS followed by ORR followed by DCR) in order to account for 
multiplicity. Any statistically significant findings occurring below a non-significant result in the 
hierarchy will be considered as exploratory findings. 
8.4.4 
Planned Interim Analyses 
This study will have an event-driven interim analysis for OS, based on O’Brien-Fleming 
boundaries. The interim analysis for OS will take place following 261 deaths. The number of 
deaths required to trigger the final analysis will be 390. 
8.4.5 
Subgroup Analyses 
Hazard ratios and 95% confidence intervals will be calculated for OS within subgroups using the 
unadjusted Cox proportional hazards model in order to evaluate the consistency of treatment 
effect. These subgroups will include those defined by the stratification factors. Other subgroups 
may also be considered, with a full list being set down in the SAP. 
Subgroup analyses of PFS will be performed in a similar way. ORR and DCR will also be 
evaluated within these same subgroups, based on the calculation of unadjusted odds ratios and 
corresponding 95% confidence intervals. 
8.4.6 
Independent Data Monitoring Committee (IDMC) 
An IDMC, composed of at least two oncologists (at least one of whom specializes in pancreatic 
cancer) and a statistician, will be set up to review the safety of eryaspase during the study and to 
review the interim analysis for efficacy. The IDMC will develop and follow an IDMC plan and 
charter. 
The IDMC will review the safety of eryaspase in combination with irinotecan-based therapy or 
gemcitabine/Abraxane regimen after 10 or more patients have been enrolled per regimen and 
have received at least one cycle of study therapy. Thereafter, and at a frequency to be defined in 
the IDMC Charter, the IDMC will be provided with reports of baseline demographics, medical 
history, concomitant medications, AEs, SAEs, and other safety data for regular review and 
recommendations.

SUPPORTING DOCUMENTATION AND OPERATIONAL CONSIDERATIONS 
9.1 
REGULATORY, ETHICAL, AND STUDY OVERSIGHT CONSIDERATIONS 
9.1.1 
Informed Consent Process 
Participation in the study is voluntary; each patient must indicate his/her agreement and 
willingness to participate by signing and dating the approved ICF prior to the initiation of any 
study-related procedures. 
The Sponsor or designee will provide an Informed Consent Form to Investigators in a separate 
document. The consent forms that are used, including the separate consent form for PGx, must 
be approved both by the Sponsor and by the reviewing IECs/IRBs. 
The ICF should be in accordance with the principles originating in the Declaration of Helsinki, 
current ICH and GCP guidelines, applicable regulatory requirements, and Sponsor policy. 
Prior to the start of any protocol-specific evaluations or screening procedures, the Investigator 
(or designated staff) will explain the nature of the study and its risks and benefits to the patient. 
Each patient will receive a copy of the ICF, which includes patient information. Patients should 
be given ample time to read the information and the opportunity to ask questions. One copy of 
the signed ICF will be given to the patient, and another will be retained with the study records by 
the Investigator. The process of obtaining informed consent should be documented in the 
patient’s medical file. 
9.1.2 
Independent Ethics Committees and Regulatory Authorities 
This clinical study will be conducted in accordance with the current ICH GCP Guidelines, as 
well as the ethical principles founded in the Declaration of Helsinki and applicable local laws 
and regulations (including European Directive 2001/20/EC, EU Regulation No. 536/2014, and 
US Code of Federal Regulations (CFR) 21). 
Before the start of the study, the Sponsor or the Sponsor’s designee will submit the clinical study 
protocol, ICF, and any other appropriate documents to regulatory authorities in accordance with 
local legal requirements. All required documents will also be submitted to the relevant 
IECs/IRBs by the Sponsor, the Sponsor’s designee, or the investigative sites, as applicable. As 
required by local regulations or by the IECs/IRBs, the Sponsor or Investigator will also submit 
the financial arrangements for the study and/or other financial interests of the Investigator or 
applicable site staff in the investigational drug or the Sponsor company. 
The study will only be conducted at sites where IEC/IRB and regulatory authority approval has 
been obtained as required. 
All substantial amendments to the study protocol will also be submitted to the IECs/IRBs and 
authorities in accordance with local legal requirements. Amendments must be evaluated to 
determine whether the ICF should also be revised. Protocol amendments must not be 
implemented without prior IEC/IRB and regulatory approval, except where necessary to 
eliminate immediate hazards to the subjects or when the changes involve only logistical or 
administrative aspects of the study (e.g., change in Sponsor contacts or telephone numbers).

The Investigator must keep a record of all communication with the IECs/IRBs and if applicable, 
between a national coordinating investigator and the IECs/IRBs. This also applies to any 
communication between the investigator (or sub-investigator, if applicable) and regulatory 
authorities. 
9.1.3 
Study Completion or Discontinuation and Closure 
The study will be considered completed with completion of the last visit of the last patient 
participating in the study. 
It is expected that each Investigator will complete the last study visit for the last patient at his/her 
site and submit all eCRFs to the Sponsor (or designee) in satisfactory compliance with the 
protocol within the time frame specified in the Clinical Trial Agreement. 
This study may be prematurely terminated if there is sufficient reasonable cause. If the study is 
prematurely terminated or suspended, the Investigator will promptly inform study participants 
and the relevant IEC/IRB, and the Sponsor will provide the reason(s) for the termination or 
suspension to competent regulatory authorities. Study participants will be contacted as 
appropriate, and will be informed of any changes to the study visit schedule. 
Circumstances that may warrant termination or suspension of the study include, but are not 
limited to: 
• Determination of unexpected, significant, or unacceptable risk to participants, 
• Demonstration of efficacy that would warrant stopping, 
• Determination that the primary endpoint has been met, 
• Determination of futility, and 
• Sponsor decision to stop development of the IMP. 
The study may resume once concerns about safety, protocol compliance, and data quality have 
been addressed to the satisfaction of the Sponsor, IEC/IRB, and/or the applicable regulatory 
agency. 
Following study completion or termination, the Investigator will provide the Sponsor, the 
IEC/IRB, and the applicable regulatory agency with final reports and summaries as required by 
local regulations (e.g., for Investigational New Drug (IND) studies, the Investigator must submit 
a written report to the Sponsor and the Ethics Committee within 3 months after the completion or 
termination of the study). 
9.1.4 
Protocol Adherence 
This protocol defines the study objectives, the study procedures, and the data to be collected on 
study patients. Under no circumstances should an Investigator collect additional data or conduct 
any additional procedures for any research-related purpose. 
Investigators will apply due diligence to avoid protocol deviations. 
All protocol deviations identified via monitoring and data review will be tracked, and all 
significant protocol deviations (i.e., major deviations that would exclude a patient from the PP 
population; to be defined in the SAP) will be reported in the Clinical Study Report (CSR). 
See Section 7.8.6 on collection protocol deviations related to COVID-19.

The Investigator is required to prepare and maintain adequate and accurate case histories 
designed to record all observations and other data pertinent to the study for each study 
participant. Study data for each enrolled patient will be entered into an eCRF by study site 
personnel using a secure, validated web-based electronic data capture (EDC) application. All 
users will be required to complete EDC training before they are given access to the system. 
Instances of missing, discrepant, or uninterpretable data will be queried to the Investigator for 
resolution, via auto-queries generated by programmed edit checks or via manual queries raised 
by site monitors and/or data managers. Any changes to the study data will be made in the eCRF; 
the EDC system will document these changes in an audit trail, which will be maintained within 
the clinical database. 
9.1.9 
eCRF Completion using Electronic Data Capture 
Guidelines for eCRF completion will be provided and will be reviewed with study personnel 
before the start of the study, and as needed during the study. 
It is the Investigator’s responsibility to ensure the accuracy, completeness, clarity, and timeliness 
of the data reported in the patient’s eCRF. All data entered in the eCRFs must be supported by 
source data. The Investigator or designee must complete eCRFs within 5 days after data are 
collected. 
The Sponsor or designee will review eCRF data for accuracy and completeness during on-site 
monitoring visits and after transmission of data to the Sponsor or designee; any discrepancies 
will be resolved with the Investigator or designee, as appropriate. After the data are uploaded 
into the clinical study database, they will be verified for accuracy. The Investigator must answer 
all queries as soon as possible. 
The Investigator will provide formal approval of all information in the eCRFs, including any 
changes made to the eCRFs, to endorse the final submitted data for patients for whom he or she 
is responsible. 
A copy of the final archival eCRF in the form of a compact disc (CD) or PDF will be provided to 
the Investigator for filing in his/her study file. The Sponsor will retain the eCRF data. 
9.1.10 
Key Roles and Study Governance 
The worldwide Sponsor of this clinical trial is ERYTECH Pharma. The Sponsor will enlist the 
support of a contract research organization (CRO), imaging management vendors, central labs, 
and statistical firms to perform the operational aspects of the trial. The Sponsor will supervise 
and practice oversight on all outsourced activities. All structures and associated procedures will 
be described in the Oversight Plan, which will include information about IMP, quality assurance, 
and vendor management.  
The Sponsor Medical Monitors will support the Investigators during the conduct of the study, 
and the Sponsor site monitor will support the site personnel and will provide the necessary 
protocol training, RECIST 1.1 training, and any additional training required for the successful

9.1.11 
Safety Oversight 
The Sponsor’s Global Drug Safety department or its designated representative will oversee, 
monitor and report AEs and SAEs to all relevant parties as required by the regulations and 
applicable laws. Continuous safety monitoring will be performed by Investigators and site 
clinicians. An IDMC will be appointed and will meet in regular intervals to monitor the safety of 
the study participants and provide recommendations to the Sponsor. 
9.1.12 
Clinical Monitoring 
In order to comply with GCP guidelines, the study sites must follow monitoring procedures 
developed by the Contract Research Organization (CRO) and approved by the Sponsor. 
The Sponsor or its designee will perform on-site monitoring visits as frequently as necessary and 
according to the Monitoring Plan developed for the study to ensure that the investigation is 
conducted according to the protocol design and regulatory requirements. The monitor will 
cross-check the data entered into the eCRFs and SAE Forms with the hospital or clinic records 
(source documents) for completeness and clarity. Data queries will be raised in the EDC system, 
findings from this review of eCRFs and source documents will be discussed with the 
investigational staff, and administrative matters will be clarified. 
At site initiation visits, the nature and location of all source documents will be identified to 
ensure that all sources of original data required to complete the eCRF are known to the Sponsor 
and investigational staff and are accessible for verification by the Sponsor site monitor. If 
electronic records are maintained at the investigational site, access to these records and methods 
of verification must be discussed with the investigational staff. 
Direct access to source documents (medical records) must be allowed for the purpose of 
verifying that the data in the eCRF are consistent with the original source data. It is expected that 
during monitoring visits the relevant investigational staff will be available, the source 
documentation will be accessible, and a suitable environment will be provided for review of 
study-related documents. The monitors will meet with the Investigator on a regular basis during 
the study to provide feedback on study conduct. 
See Section 7.8.7 for further information regarding Clinical Monitoring related to COVID-19. 
9.1.13 
Site Audits and Inspections 
The Sponsor is responsible for implementing and maintaining quality assurance (QA) and quality 
control (QC) systems, and for performing systematic and independent auditing of study conduct, 
data generation, documentation, analysis, and reporting to determine whether the evaluated 
activities are being performed in compliance with the protocol, the Sponsor’s standard operating 
procedures, GCP, and applicable local regulatory requirements. 
Representatives of the Sponsor’s clinical QA department or designee may visit the site at any 
time during or after completion of the study to conduct an audit of the study in compliance with 
regulatory guidelines and company policy. Similar auditing procedures may also be conducted 
by agents of any IRB/IEC or regulatory body, either as part of a national GCP compliance 
program or to review the results of this study in support of a regulatory submission. The

prognosis in individual patients. The lower the Karnofsky score, the worse the survival for most 
serious illnesses.
