NEOD001-OLE 251 PROTOCOL SYNOPSIS 
Title 
A Phase 2b Open-label Extension Study to Evaluate the Long-
term Safety and Efficacy of NEOD001 in Subjects with Light 
Chain (AL) Amyloidosis who were previously enrolled in Study 
NEOD001-201 (PRONTO) 
Phase 
2b 
Planned Number of Study 
Sites 
Approximately 40 sites globally 
Objective 
The objective of this study is to evaluate the long-term safety and 
efficacy of NEOD001 in subjects with AL amyloidosis who have 
completed Study NEOD001-201. 
Study Design 
This is a global, multicenter, Phase 2b, open-label extension study 
of subjects with AL amyloidosis who had a hematologic response 
(Appendix 1) to first-line treatment for their amyloidosis (e.g., 
chemotherapy, autologous stem cell transplant [ASCT]) and 
completed Study NEOD001-201. Subjects in this study may 
receive concomitant chemotherapy. 
Subject screening will occur during the 28 days prior to the 
first administration of study drug (i.e., Month 1-Day 1 Visit), 
which may overlap with the last visit in Study NEOD001-201. 
If all eligibility requirements are met, the subject will be 
enrolled and Screening assessments (Table 1) will be 
completed.  
Study visits will occur every 28 days based on scheduling from 
Month 1-Day 1. A ±5-day window is allowed for visits starting 
after Month 1. Subjects who discontinue study drug before the 
End of Study (EOS) Visit should have an Early Treatment 
Discontinuation (ETD) Visit 30 (±5) days after their final 
administration of study drug. 
Number of Subjects 
Approximately 100 subjects will be enrolled. 
Study Drug, Dose, and 
Mode of Administration 
Study drug consists of NEOD001 24 mg/kg (dose not to exceed 
2500 mg). NEOD001 will be administered as an intravenous (IV) 
infusion once every 28 days (a ±5-day window is allowed for 
visits starting after Month 1) over 60 (±10) minutes unless a 
longer infusion duration was established for the individual subject 
in Study NEOD001-201. A minimum of 21 days between doses is 
required. Subjects should be closely monitored per Section 5.3 
following completion of the study drug infusion.

serum and urine immunofixation electrophoresis (IFE)  
• Severity of disease-related symptoms including any changes

Statistical Considerations 
and Methods 
Analysis Populations: 
All analyses will be based on the Safety Population, defined as all 
subjects who receive any amount of study drug. 
Select analyses will use efficacy subsets, defined as: 
• Renal Evaluable Population: subjects who had renal 
involvement in Study NEOD001-201 
• Peripheral Neuropathy Evaluable Population: subjects who 
had peripheral nerve involvement in Study NEOD001-201   
• Hepatic Evaluable Population: subjects who had hepatic 
involvement in Study NEOD001-201 
Safety Analyses: 
Safety will be assessed through changes in vital signs, 12-lead 
ECGs, laboratory test results, and summaries of AEs. All 
treatment-emergent adverse events (TEAEs) and serious adverse 
events (SAEs) will be summarized.  
Efficacy Analyses: 
Response rates will be summarized including 95% confidence 
intervals. The distributions of time-to-event endpoints 
(progression-free survival, overall survival) will be summarized 
using the Kaplan-Meier method.  
All quantitative endpoints, except 6MWT distance, defined as the 
change from baseline will be analyzed using linear mixed models 
for repeated measurements (MMRM). The dependent variable 
will be the change from baseline at each time point. The model 
will include fixed effects for time point and treatment-by-time 
interaction. The baseline value of the corresponding endpoint will 
be included as a covariate and the unstructured covariance model 
will be used. The denominator degrees of freedom will be 
estimated using the Kenward-Roger approximation. The 6MWT 
distance change from baseline will be analyzed using a Wilcoxon 
signed rank test.

INTRODUCTION 
1.1 
Light Chain (AL) Amyloidosis 
Systemic amyloidoses are a complex group of diseases caused by tissue deposition of misfolded 
proteins that result in progressive organ damage. The most common type, light chain (AL) 
amyloidosis or primary systemic amyloidosis, is a rare disease that involves a hematologic 
disorder caused by clonal plasma cells that produce misfolded immunoglobulin light chains. 
Overproduction of misfolded light chains by plasma cells results in both soluble, aggregated 
forms of light chains and insoluble, fibrillar deposits of abnormal AL protein (amyloid), in the 
tissues and organs of individuals with AL amyloidosis. Clinical features of AL amyloidosis 
include a constellation of symptoms and organ dysfunction including cardiac, renal, and hepatic 
dysfunction, and gastrointestinal involvement, neuropathy, and macroglossia. The mechanisms 
by which amyloidogenic immunoglobulin light chains result in organ dysfunction are not well 
characterized, however, it is believed that both amyloid deposits and prefibrillar aggregates may 
contribute to cytotoxic effects on organs observed in patients with AL amyloidosis.  
Approximately three-fourths of AL amyloidosis patients present with 1 or 2 major organ systems 
involved (e.g., cardiac, renal, hepatic, peripheral nervous system, autonomic nervous system, 
gastrointestinal tract, soft tissues) while a quarter of patients present with >2 systems involved 
(Palladini et al, 2005; Gertz et al, 2010). AL amyloidosis is most commonly associated with 
cardiac and/or renal dysfunction, with overt restrictive cardiomyopathy observed in 
approximately 50% of all cases, and subclinical cardiac involvement detected in almost every 
case at autopsy or on endomyocardial biopsy (Falk and Dubrey, 2010). 
AL amyloidosis has two important disease components. The first component is the plasma cell 
dyscrasia (PCD), which results in the overproduction of immunoglobulin light chain, and the 
second component is the impact of the soluble and insoluble amyloid on organ structure and 
function, leading to the clinical manifestations of the disease. Currently, there are no approved 
treatments for AL amyloidosis and no existing treatments that directly neutralize the toxic 
soluble aggregates or remove the deposited misfolded amyloid that are thought to cause organ 
dysfunction (Falk and Dubrey, 2010). The current standard of care for patients with AL 
amyloidosis is aimed at reducing or eliminating the bone marrow disorder, the PCD. The most 
aggressive treatment options include autologous stem cell transplant (ASCT) and high-dose 
chemotherapy for those patients who can tolerate it. Other treatment regimens include 
combinations of drugs often used to treat hematological malignancies including melphalan, 
prednisone, dexamethasone, and proteasome inhibitors (e.g., bortezomib), in an attempt to 
reduce light chain production.  
The incidence of treatment-related mortality following ASCT is high, although variable and 
treatment center dependent, with the greatest mortality occurring in patients with cardiac 
involvement (Falk and Dubrey, 2010). Falk and colleagues noted that although complete 
hematologic responses could be achieved in approximately 40% of treated patients (Falk and 
Dubrey, 2010), the rate of any organ function improvement or stabilization (“organ response”) 
after achieving hematologic response from ASCT or chemotherapy regimens is highly variable 
(Cibeira et al, 2011; Cohen et al, 2007; Michael et al, 2010). Hematologic response in the 
absence of organ benefit provides limited, if any, clinical benefit to patients with AL amyloidosis

(Kaufman et al, 2015), underscoring that the major determinant of morbidity and mortality is end 
organ damage. 
Unlike other hematologic disorders such as multiple myeloma, the morbidity and mortality of 
AL amyloidosis is related to organ dysfunction rather than the PCD. In all patients with AL 
amyloidosis, disease outcome is highly dependent on the severity of organ involvement, 
especially cardiac involvement; and prognosis can be defined by N-terminal pro-brain natriuretic 
peptide (NT-proBNP). NT-proBNP was chosen as the primary endpoint for the Phase 2b 
Study NEOD001-201 because it is a clinically validated cardiac functional biomarker of injury 
and dysfunction and decreasing NT-proBNP levels predict lower mortality rates (Comenzo et al, 
2012). NT-proBNP can also be used for early assessment of cardiac response, allowing treatment 
modification (Palladini et al, 2014). In Study NEOD001-001, the Phase 1/2 study of NEOD001 
in subjects with AL amyloidosis, monthly infusions of NEOD001 resulted in clinically 
meaningful reductions in NT-proBNP (Gertz et al, 2016). 
AL amyloidosis is a rare disorder. NEOD001 was designated as an Orphan Medicinal Product in 
the European Union on 08 February 2013 for the treatment of AL amyloidosis and in the US on 
17 February 2012 for the treatment of AA amyloidosis and AL amyloidosis.  
1.2 
Background on NEOD001 
Prothena Therapeutics Limited (Prothena) is developing NEOD001, a humanized 
immunoglobulin G1 (IgG1), kappa version of 2A4, the parent murine monoclonal antibody. 
NEOD001 and 2A4 bind specifically and with nanomolar affinity to a cryptic epitope only 
exposed on AL amyloid fibrils and soluble aggregates, but not available for binding on normally 
folded light chains that compose immunoglobulins (Ig) or on free non-amyloid light chain in 
circulation. NEOD001, administered by intravenous (IV) infusion, is proposed for use to target 
the misfolded light chain protein in subjects with AL amyloidosis. Refer to the current 
NEOD001 Investigator’s Brochure for detailed nonclinical and clinical information. 
The proposed mechanism of action for NEOD001 is thought to be two-pronged (Figure 2). The 
first is the direct interaction of NEOD001 with misfolded, soluble light chain aggregates 
resulting in the neutralization of these cytotoxic moieties. The second is the clearing of insoluble 
toxic light chain amyloid deposited in organs/tissues via an antibody-dependent cellular 
phagocytosis (ADCP) mechanism. It is believed that NEOD001 binds (opsonizes) amyloid 
deposits, and signals monocytes/macrophages to initiate the phagocytosis process that ultimately 
removes the amyloid deposits from affected organs. Both mechanisms may contribute to 
potential clinical benefit.

In a 28-day, weekly IV dose study of NEOD001 in cynomolgus monkeys with a 28-day 
dose-free period for control and high dose animals, treatment was well tolerated at all dose levels 
(10, 50, and 100 mg/kg/week). There were no NEOD001-related changes in any of the study 
parameters evaluated and thus the no-observable-adverse-effect-level (NOAEL) for NEOD001 
in this species was 100 mg/kg. Serum levels of NEOD001 were maintained throughout the 
treatment period. The data suggest a low risk of off-target toxicity. 
H2/hIL-6 TRIAD mice:  The TRIAD mouse model of AA amyloidosis has limitations relative 
to safety assessment for AL amyloidosis; e.g., 1) this transgenic model overexpresses human 
interleukin-6 (IL-6), creating an exaggerated pro-inflammatory baseline state that is important 
for disease progression but can confound safety evaluation, 2) the disease state is also promoted 
by injection with an amyloid extract, called amyloid-enhancing factor (AEF), intended to seed 
tissue with amyloid, and 3) it involves an amyloid protein (AA) that is different than the one 
targeted in this population (AL), despite the fact that 2A4 recognizes both proteins. However, 
this model contributes to the safety assessment of NEOD001 as it is the only nonclinical model 
available that offers the ability to assess the potential hazards of antibody binding to amyloid 
embedded in various vital organs in periphery, primarily liver, spleen, and kidney. The murine 
homologue of NEOD001, 2A4, maintains full effector function and was used in these studies. 
Two TRIAD mouse studies were used in the nonclinical safety assessment: a 22-day toxicity 
study by the IV route of administration and a 28-day toxicity study by IV and SC routes of 
administration. In addition, a 22-day special immunogenicity/toxicity study in H2/hIL-6 mice 
(no AEF) was conducted to compare 2A4 against the immunogenic potential of an unrelated 
protein, bovine serum albumin (BSA). 
As intended for this disease model, the TRIAD mouse has background pathology. Appropriate 
controls demonstrated the effect of the IL-6 transgene (plasmacytosis in spleen, thrombus 
formation in mesenteric vessels) and the effect of the IL-6 transgene with AEF added (amyloid 
deposition in kidney, liver, spleen, and other tissues; inflammatory infiltrates in the heart; and 
renal pathology, including tubular degenerative changes and papillary necrosis). Importantly, no 
additional pathology was observed that was attributable to 2A4 treatment at the doses studied, 
4 and 40 mg/kg/week.  
In both toxicity studies, mortality was observed acutely following the third weekly dose 
(Study Day 15) when 2A4 was administered by bolus IV administration. No pathology was 
present to indicate mechanism of the cause of death. The timing of the adverse reaction being 
within minutes to hours of the third weekly dose, and the identified presence of anti-drug 
antibodies (ADAs), suggest that the effect is an ADA-mediated phenomenon in this model. In 
animals that survived, there were no adverse effects described surrounding deposited amyloid, or 
in other tissues. Anti-drug antibody reactions in animal species are not predictive of human 
responses and, therefore, these effects are not considered to contribute to human risk assessment 
(Bugelski and Treacy, 2004; Pimm and Gribben, 1992). Additionally, while it is possible that 
ADAs might develop, it is not known whether or not this would be associated with any clinical 
significance.

A special immunogenicity/toxicity study was conducted to explore whether the mortality 
observed following IV dosing of 2A4 in the TRIAD mouse can be observed with an unrelated, 
but immunogenic protein. Nontransgenic/wild-type (WT) mice and H2/hIL-6 transgenic mice 
(no AEF administered) were treated once weekly by IV administration with 2A4 at 4 mg/kg. The 
nontransgenic mice showed no systemic effects; however, the IL-6 overproducing mice 
developed profound signs (decreased motor activity, hunched posture, ataxia, cold to touch) 
immediately after dosing on Days 15 and 22, replicating what was observed in the TRIAD 
mouse safety studies above. Mortality and moribundity occurred post dosing on Day 22. Another 
group of H2/hIL-6 transgenic mice was treated once weekly by IV administration with BSA at 
50 mg/kg. A similar clinical course occurred although signs began one week earlier; i.e., after 
dosing on Day 8 (the second dose). Again, mortality was observed in some animals after dosing 
on Day 22. This study demonstrates the importance of elevated IL-6 in the morbidity and 
mortality observed in this model and further demonstrates that the mortality is not unique to 2A4 
but can be seen with other proteins that are immunogenic in this mouse model. 
Human tissue cross-reactivity:  In a human tissue cross-reactivity study of NEOD001 designed 
to examine potential off-target effects, a limited number of tissues demonstrated any binding. 
Cytoplasmic staining was observed in the heart, kidney, pancreas, pituitary, and testis. 
Cytoplasmic staining is generally not considered to be relevant to IV dosing as these sites are not 
accessible to the administered antibody. Rare to occasional, mild-intensity membrane staining 
was observed on ductular and tubular epithelial cells of the pancreas and testis, respectively. No 
pathologic changes were observed in these organs in the repeat-dose studies suggesting limited 
safety liabilities from potential binding in these tissues. Overall, these data confirm the 
prediction of a low potential for binding of NEOD001 to normal tissue. 
In summary, the available nonclinical data support the safety and efficacy for the continued 
clinical development of NEOD001 for the treatment of AL amyloidosis. No target organ toxicity 
has been described. Based on available models, there are limitations on the ability to assess the 
interaction of NEOD001 with deposited or soluble AL amyloid. The investigations in an AA 
amyloidosis model (the TRIAD mouse) provide some reassurance that binding of 2A4, an 
antibody with full effector function, does not appear to adversely react with deposited amyloid in 
tissue. Nevertheless, monitoring for changes in disease pathology, as would typically be 
performed in clinical development, is warranted. 
1.2.2 
Clinical Experience 
The safety and tolerability of NEOD001 have been investigated in the Phase 1/2 study 
(Study NEOD001-001) in the US, and are being investigated in the following ongoing global 
studies: 
• Phase 1/2 open-label extension study (Study NEOD001-OLE001) 
• Phase 2b study (Study NEOD001-201) 
• Phase 3 study (Study NEOD001-CL002)

Study NEOD001-001 was an open-label, dose escalation study of the IV administration of 
single-agent NEOD001 in subjects with AL amyloidosis, which enrolled 27 subjects in the 
Escalation Phase in 7 cohorts (evaluating dose levels from 0.5 mg/kg to 24.0 mg/kg) and 
enrolled an additional 42 subjects in the Expansion Phase. The most frequently reported 
treatment-emergent adverse events (TEAEs) overall in Study NEOD001-001 (occurring in ≥10% 
of subjects [N=69], regardless of relationship to NEOD001) were fatigue, nausea, upper 
respiratory tract infection, peripheral edema, diarrhea, anemia, increased blood creatinine, 
dizziness, cough, constipation, headache, vomiting, dyspnea, pain in extremity, back pain, 
muscle spasms, rash, and urinary tract infection (Gertz et al, 2016). No confirmed anti-
NEOD001 antibodies were detected. No dose-limiting toxicities (DLTs) or related serious 
adverse events (SAEs) were reported. 
Efficacy data from the completed Study NEOD001-001 were reported by Gertz et al. (2016) and 
are summarized herein. Cardiac response was assessed by the clinically relevant cardiac 
biomarker, NT-proBNP, using Comenzo et al, 2012 criteria (Appendix 3). Thirty-six subjects 
were considered cardiac evaluable (i.e., baseline NT-proBNP ≥650 pg/mL). Among cardiac-
evaluable subjects, 53% (n=19) met the criteria for cardiac best response and 47% (n=17) met 
cardiac best response category of stable disease. Renal response was defined according to 
Palladini et al (2014) criteria (Appendix 3). Thirty-six subjects were considered renal evaluable 
(i.e., baseline proteinuria ≥0.5 g/24 hours). Among renal-evaluable subjects, 64% (n=23) met the 
criteria for renal best response and 36% (n=13) met renal best response category of stable 
disease. Peripheral neuropathy response was defined according to Coelho et al (2012) criteria 
(Appendix 3). Eleven subjects in the Peripheral Neuropathy Expansion Cohort were considered 
peripheral neuropathy evaluable. Among peripheral neuropathy-evaluable subjects, 82% (n=9) 
met the criteria for neuropathy response (i.e., <2-point increase in Neuropathy Impairment 
Score–Lower Limbs [NIS-LL] score [88-point scale] from baseline) and 18% (n=2) were 
progressors. Two of the responders had complete resolution of peripheral neuropathy. 
Eligible subjects from Study NEOD001-001 are being enrolled in Study NEOD001-OLE001, an 
open-label extension study to evaluate the long-term safety and tolerability of NEOD001 in 
subjects with AL amyloidosis. Subjects receive 24 mg/kg NEOD001 once every 28 days using 
the infusion duration established for the individual subject in Study NEOD001-001 or over 
60 (±10) minutes.

Study NEOD001-201 (PRONTO)  is an ongoing Phase 2b, multicenter, global, randomized, 
double-blind, placebo-controlled, two-arm, parallel group efficacy and safety study of NEOD001 
as a single agent administered intravenously in adults with AL amyloidosis who had a 
hematologic response to first-line treatment for their amyloidosis (e.g., chemotherapy, ASCT) 
and have persistent cardiac dysfunction. Subjects are randomized in a 1:1 ratio to receive either 
NEOD001 (24 mg/kg) or placebo. Eligible subjects from Study NEOD001-201 may be enrolled 
in this open-label extension study (NEOD001-OLE251). As of 30 September 2016, 23 subjects 
were enrolled in Study NEOD001-201 and received 24 mg/kg NEOD001 or placebo (treatment 
remains blinded). One subject experienced a serious TEAE and no deaths were reported. A 64-
year-old male experienced vasovagal syncope (characterized by bradycardia, hypotension, and 
syncope), which the Investigator assessed as Common Terminology Criteria for Adverse Events 
(CTCAE) Grade 3, serious, and related to study drug (treatment remains blinded). The subject 
recovered/resolved from the event of vasovagal syncope and discontinued the study on the day of 
the event. 
Study NEOD001-CL002 (VITAL) is an ongoing Phase 3, multicenter, international, randomized, 
double-blind, placebo-controlled, two-arm efficacy and safety study in subjects with AL 
amyloidosis. Newly diagnosed subjects with AL amyloidosis are randomized in a 1:1 ratio to 
received either NEOD001 (24 mg/kg) plus standard of care or placebo plus standard of care, 
administered once every 28 days as a 1- to 2-hour IV infusion. All subjects are premedicated 
with 25 mg diphenhydramine (or an equivalent dose of an H1 antihistamine) and 650 mg 
acetaminophen (or an equivalent dose of paracetamol) within 30 to 90 minutes prior to the start 
of the infusion. As of 30 September 2016, 129 subjects were enrolled in the Phase 3 Study 
NEOD001-CL002 and received NEOD001 24 mg/kg plus standard of care OR placebo plus 
standard of care (treatment remains blinded). Sixty-five (50.4%) subjects experienced at least 1 
serious TEAE, none of which were considered by the Investigator to be related to study drug 
treatment (blinded). As of the data lock point, 19 (14.7%) subjects had died; none of the deaths 
were considered by the Investigator to be related to study drug treatment (blinded). Five (3.9%) 
subjects had TEAEs that lead to study drug discontinuation.  
Due to the limited number of infusion-site related reactions reported to date, premedication of 
subjects prior to the start of NEOD001 infusion is not required in the NEOD001-OLE001, 
NEOD001-201, and NEOD001-OLE251 protocols. As of 30 September 2016, 221 subjects had 
been dosed in the 4 completed or ongoing studies. In Study NEOD001-CL002 (VITAL), 
129 subjects received a total of 534 infusions of blinded study drug (24 mg/kg NEOD001 plus 
standard of care or placebo plus standard of care). In Study NEOD001-201 (PRONTO), 
23 subjects received a total of 51 infusions of blinded study drug (24 mg/kg NEOD001 or 
placebo). In Study NEOD001-001, 69 subjects received 994 infusions of NEOD001 (up to doses 
of 24 mg/kg) and 31 of these subjects had gone on to receive 59 infusions of 24 mg/kg 
NEOD001 in the open-label extension study (NEOD001-OLE001). In the completed Study 
NEOD001-001, 6 subjects experienced 9 infusion-site reactions were reported (6 subjects) and 
most (n=7; 78%) were classified as Grade 1. As noted above, 1 subject in the ongoing 
Study NEOD001-201 experienced an event of vasovagal syncope (characterized by bradycardia, 
hypotension, and syncope). Another aspect of safety monitoring in studies of NEOD001 has 
been a required postinfusion observation time ranging from 60 to 120 minutes. Studies 
NEOD001-201 and NEOD001-OLE251 allow for flexibility in monitoring time if no reactions 
are seen after the first 2 infusions, as described in Section 5.3.

Based on the data available to date, NEOD001 has been well tolerated as single-agent therapy in 
subjects with AL amyloidosis and no clinically significant safety signals have been identified. 
1.3 
Rationale for Study Conduct, Design, and Dose Selection 
Study NEOD001-OLE251 is an open-label extension study, designed to allow subjects who 
completed Study NEOD001-201 to receive active treatment and to evaluate the long-term safety 
and efficacy of NEOD001 as a single agent in subjects with AL amyloidosis who were 
previously treated with PCD therapies. The selected dose of NEOD001, 24 mg/kg (dose not to 
exceed 2500 mg), was used in Study NEOD001-201 and will be continued in this study and the 
other ongoing studies of NEOD001. 
NEOD001 is currently being studied in 3 other ongoing studies. Study NEOD001-201 is a 
double-blinded, randomized, controlled Phase 2b study designed to evaluate the efficacy and 
safety of NEOD001 as a single agent in patients with AL amyloidosis whose underlying PCD is 
stable but who still exhibit significant cardiac impairment. Study NEOD001-CL002 is a double-
blinded, randomized, placebo-controlled Phase 3 study in patients with newly diagnosed AL 
amyloidosis disease who are receiving chemotherapy to treat the underlying PCD. In addition, 
Study NEOD001-OLE001, an open-label extension study for subjects previously enrolled in the 
Phase 1/2 Study NEOD001-001, allows subjects to receive NEOD001 and concomitant 
chemotherapy for treatment of their underlying PCD.

STUDY PLAN 
3.1 
Study Design 
This is a global, multicenter, Phase 2b, open-label extension study of subjects with AL 
amyloidosis who had a hematologic response (Appendix 1) to first-line treatment for their 
amyloidosis (e.g., chemotherapy, ASCT) and completed Study NEOD001-201. Subjects in this 
study may receive concomitant chemotherapy (see Section 5.6.1). 
Subject screening will occur during the 28 days prior to the first administration of study drug 
(i.e., Month 1-Day 1 Visit), which may overlap with the last visit in Study NEOD001-201. If all 
eligibility requirements are met, the subject will be enrolled and Screening assessments will be 
completed. Screening assessments are listed in Table 1.  
Study visits will occur every 28 days based on scheduling from Month 1-Day 1. A ±5-day 
window is allowed for visits starting after Month 1. Subjects may receive up to 36 infusions of 
study drug. Subjects who discontinue study drug before the End of Study (EOS) Visit should 
have an Early Treatment Discontinuation (ETD) Visit 30 (±5) days after their final 
administration of study drug.

15. Subject is under legal custodianship 
4.3 
Early Treatment Discontinuation 
If the subject discontinues study drug prior to the EOS Visit, they should return for an ETD Visit 
30 (±5) days after their final administration of study drug as per Section 6.1.3. If a subject fails to 
return for the scheduled visit, a documented effort must be made to determine the reason. If the 
subject cannot be reached by telephone after 2 attempts, a certified letter will be sent to the 
subject (or the subject’s legally authorized representative, if appropriate) requesting contact with 
the Investigator. This information will be recorded in the study records. 
Reasons for early discontinuation from study drug treatment may include, but are not limited to: 
• Need for organ transplant

• A suspected NEOD001-related clinically significant immunologic reaction – collect 
additional serum samples, if possible, during the period following the treatment stoppage to 
allow for the determination of the persistence of anti-NEOD001 antibodies. At a minimum, 
samples should be collected at the ETD Visit and 3 months after the ETD Visit, if the subject 
agrees to return to the clinic.  
• Occurrence of an AE or clinically significant laboratory abnormality that, in the opinion of 
the Investigator, warrants the subject’s permanent discontinuation from study drug treatment; 
the Medical Monitor should be notified as soon as possible of any discontinuation of study 
drug due to an AE 
• Suspected or confirmed pregnancy or nursing during study treatment period. Female subjects 
whose pregnancy test is positive at the ETD Visit must be followed to term or until 
termination of the pregnancy (Section 7.4.2). 
After the ETD Visit, vital status follow-up phone calls should be made per Section 6.3. 
4.4 
Early Termination from the Study 
Early termination occurs if the subject fails to complete the entire study, through the EOS Visit. 
Subjects may withdraw their consent to participate in this study at any time without prejudice. 
The Investigator must withdraw from the study any subject who requests to be withdrawn. A 
subject’s participation in the study may be discontinued at any time at the discretion of the 
Investigator in accordance with his/her clinical judgment. The Sponsor or its designee should be 
notified in a timely manner of all subject discontinuations. When possible, the tests and 
evaluations listed for the ETD Visit should be carried out. 
Early termination from the study may occur if: 
• In the opinion of the Investigator, the subject cannot safely participate in the procedures 
required by the protocol 
• Subject withdraws consent 
• Subject is unwilling or unable to comply with the study requirements 
• Subject is lost to follow-up 
Vital status will be collected within legal and ethical boundaries for all screened subjects and 
will be searched in public sources. During the study close-out period, survival status will be 
collected within legal and ethical boundaries for all subjects who withdrew participation from the 
study. If vital status is determined, the subject will not be considered lost to follow-up. 
4.5 
Replacement of Subjects 
As this is an open-label study for subjects who completed Study NEOD001-201, no subjects will 
be replaced.

TREATMENT OF SUBJECTS 
5.1 
Study Drug 
Study drug consists of NEOD001. 
5.1.1 
Formulation and Packaging of NEOD001 
The active study drug, NEOD001, is supplied as a sterile, lyophilized dosage form in a 20/25 mL 
vial containing 500 mg/vial NEOD001. After reconstitution with 9.6 mL of sterile water for 
injection (WFI), the vial will contain 50 mg/mL of NEOD001, 25 mM L-Histidine, 230 mM 
Trehalose, and 0.02% Polysorbate 20. The labelling will comply with applicable regulatory 
requirements. 
5.1.2 
Shipping, Storage, and Handling of NEOD001 
NEOD001 will be shipped to clinical sites in individual cartons (one vial per carton). Upon 
receipt, a study staff member will place the NEOD001 in a refrigerator at a temperature ranging 
from 2°C to 8°C in a secure, locked location. Access to the NEOD001 should be strictly limited 
to the study staff. Neither the Investigator nor any member of the study staff will distribute any 
of the study supplies to any person who is not participating in this study. 
If a study staff member becomes aware that the NEOD001 has not been properly handled (e.g., 
supply arrived at room temperature or was not placed in refrigerator upon receipt), follow the 
procedure outlined in the Pharmacy Manual or immediately contact the Study Monitor (contact 
information available in the Study Manual). In such an event, NEOD001 should be quarantined 
in a 2°C to 8°C refrigerator and must not be administered to any subject until the drug has been 
approved for use. 
It is expected that the site staff will maintain refrigerator temperature logs in the investigational 
product storage area, recording the temperature at least once each working day. 
Refer to Section 5.3 and the Pharmacy Manual for further details about shipping, storage and 
handling of NEOD001. 
5.2 
Accountability and Return of Study Supplies 
The study drug will be dispensed at the discretion of the Investigator in accordance with the 
conditions specified in this protocol. It is the Investigator’s responsibility to ensure that accurate 
records of study drug disposition and return are maintained. 
All study drugs provided by the Sponsor or provided at the study center should be retained at the 
site until otherwise instructed in writing by the Sponsor. Upon completion of the study or 
termination of the investigational site, all unused vials of study drug supplied by the Sponsor can 
be destroyed locally as per local institutional guidelines and a copy of the destruction certificate 
supplied to the Sponsor or may be shipped to a depot designated by the Sponsor. Refer to the 
Pharmacy Manual for additional information.

5.3 
Dosage, Preparation, and Administration 
Study drug consists of NEOD001. The NEOD001 dose is 24 mg/kg; however, the maximum 
dose administered is not to exceed 2500 mg. Therefore, subjects with a weight of 104.2 kg or 
greater will receive the maximum dose of 2500 mg. The subject’s weight during Screening may 
be used for calculation of the first dose. Subsequent doses may be calculated based on the current 
weight at that visit or using the Screening weight, based on the site’s institutional guidelines. A 
change of ±10% from the weight being used for dosing should trigger recalculation of the dose 
based on the new weight unless thought to be exclusively due to fluid fluctuation (e.g., edema). 
Each vial of 500 mg of NEOD001 will be reconstituted with 9.6 mL sterile WFI to a 
concentration of 50 mg/mL resulting in a buffered, isotonic, preservative-free solution with a 
total extractable volume of 10 mL. Study drug will be prepared in a 250 mL IV bag of 0.9% 
saline. The equivalent volume of reconstituted NEOD001 will be withdrawn prior to transferring 
the drug solution into the IV bag, such that the total IV bag volume will be 250 mL. Refer to the 
Pharmacy Manual for complete information on preparing and administering the study drug.  
The Pharmacy Staff at each site will be responsible for preparing the study drug. 
The study drug should only be administered in settings where emergency resuscitative equipment 
and personnel trained in the management of anaphylaxis are immediately available to treat 
systemic reactions under the direct supervision of a physician.  
NEOD001 will be administered once every 28 days (a ±5-day window is allowed for visits 
starting after Month 1) over 60 (±10) minutes unless a longer infusion duration was established 
for the individual subject in Study NEOD001-201. A minimum of 21 days between doses is 
required. The length of the infusion may be extended over a longer period of time if and when it 
is clinically indicated. 
NEOD001 contains no antimicrobial preservatives. Once reconstituted, storage of study drug, 
inclusive of dilution and administration, should be limited to 24 hours under refrigerated conditions 
or 4 hours at room temperature. If it is anticipated that the infusion will extend beyond 4 hours, 
the reconstituted study drug should be split into multiple bags to ensure that no amount of 
reconstituted study drug will be at room temperature for longer than 4 hours (i.e., from the time 
of reconstitution of the vial to end of the infusion of a bag). The additional bag(s) should remain 
refrigerated until ready for use. The volume contained in the administration tubing should be 
completely flushed using 30 mL of 0.9% Sodium Chloride Injection (USP) after administration 
of study drug. The infusion line should NOT be used for blood draws. 
Postdose Monitoring Period: All subjects will be closely monitored after completion of the 
study drug infusion as follows: 
• If it has been <60 days since the subject’s last visit in Study NEOD001-201, the subject 
should be monitored according to the observation time established for the individual subject 
in Study NEOD001-201 
• If it has been ≥60 days since the subject’s last visit in Study NEOD001-201, the subject 
should be monitored for 90 (±10) minutes for at least the first two infusions 

Study Drug: NEOD001 
CONFIDENTIAL 
Study Protocol: NEOD001-OLE251 
Original Protocol:  09 January 2017 
Page 43 of 100 
• Beginning with the third infusion, the Investigator may decrease the monitoring time to no 
less than 60 minutes, if no infusion-related reactions were observed in the previous infusions 
and allowed per the IRB/IEC 
• The Investigator may increase the monitoring time if deemed appropriate or per local 
standards. In the event of any clinical concerns or suspicious signs or symptoms after the 
infusion, the subject will remain under observation for as long as the Investigator deems it 
appropriate.  
5.4 
Dosage Adjustments 
5.4.1 
Withholding of Study Drug 
Subjects with symptomatic orthostatic hypotension and/or systolic BP <85 mmHg, which in the 
medical judgment of the Investigator would interfere with subject’s ability to safely receive 
study drug, will have study drug withheld until the next scheduled monthly administration, but 
should still have all other study visit assessments completed. If study drug is withheld and 
subsequently rescheduled, central laboratory assessments required for that visit will need to be 
repeated if they were drawn >7 days prior to the rescheduled dosing date. A symptom-directed 
physical exam and vital signs need to be repeated prior to each dosing.  
5.4.2 
Management of Suspected Systemic Infusion-Related/Hypersensitivity Adverse 
Events 
In the event of a suspected systemic infusion-related and/or hypersensitivity AE, the infusion 
should be immediately discontinued and appropriate supportive therapy should be administered 
per institutional practice, which may include, but is not limited to, epinephrine, IV fluids, 
corticosteroids, vasopressors, oxygen, bronchodilators, antihistamines, or 
acetaminophen/paracetamol. Subjects should be evaluated and carefully monitored until there is 
complete resolution of the AE (i.e., all hypersensitivity signs and symptoms have resolved). In 
addition to the institution’s recommended assessments, blood samples should be obtained in the 
event of a suspected systemic infusion-related and/or hypersensitivity AE for assessment of the 
following: cytokine levels (IL-6, IL-8, TNF-alpha, and INF-gamma) complements C3, C4, and 
CH50; C-reactive protein (CRP), serum amyloid A/acute phase serum amyloid A (SAA/A-
SAA); tryptase (serial levels: within 30 to 120 minutes of onset AND at 48 to 72 hours); serum 
NEOD001; and anti-NEOD001 antibody levels. If possible, samples should be collected while 
the acute symptoms persist. 
For subjects with a Grade 2 infusion-related AE, if it is appropriate to restart the infusion, the 
infusion rate should be decreased by 50% (e.g., if the infusion was previously administered over 
60 minutes, the new rate should be based on administering 250 mL over at least 90 minutes). If 
the subject is to receive additional infusions in subsequent weeks, the rate of these infusions 
should be discussed with and agreed upon prospectively by the Investigator and the Medical 
Monitor. In addition, for all subsequent infusions, maximal premedication must be administered 
according to institutional practice and should include an H1 blocker, an H2 blocker, an 
antipyretic such as acetaminophen/paracetamol and a steroid (e.g., 25-50 mg hydrocortisone IV). 

Study Drug: NEOD001 
CONFIDENTIAL 
Study Protocol: NEOD001-OLE251 
Original Protocol:  09 January 2017 
Page 44 of 100 
If a subject experiences a Grade 3 infusion-related and/or hypersensitivity AE, the infusion 
should not be restarted. The decision to continue dosing this subject at their next scheduled 
administration should be discussed with the Medical Monitor. If the decision is made to proceed 
with subsequent dosing, both the dose and infusion rate will be reduced by 50% from the 
original dose (i.e., 12.5 mg/kg in 250 mL) and infusion rate (e.g., over at least 90 minutes [if the 
previous infusion time was 60 minutes]). In addition, maximal premedication must be 
administered according to institutional practice and should include an H1 blocker, an H2 blocker, 
an antipyretic such as acetaminophen/paracetamol and a steroid (e.g., 25-50 mg hydrocortisone 
IV). Subjects who have an infusion-related and/or hypersensitivity AE at the subsequent 
scheduled study drug administration must have study drug permanently discontinued and have an 
ETD Visit per Section 6.1.3. 
Subjects who experience a Grade 4 infusion-related and/or hypersensitivity AE must have study 
drug permanently discontinued and have an ETD Visit per Section 6.1.3. 
5.4.3 
Dose Reductions 
Dose reductions may be allowed in the event that an observed AE is believed to be related to 
study drug, and upon consultation between the Investigator and the Medical Monitor, is 
considered to be manageable by a 50% reduction in dose. The duration of the dose reduction will 
be at the Investigator’s discretion. 
5.5 
Treatment Compliance 
Treatment compliance will be documented in the electronic case report form (eCRF) by 
recording the date, time, and whether or not each IV dose of study drug was completely infused, 
along with reasons why treatment was adjusted or not administered, if applicable. 
5.6 
Prior and Concomitant Medication/Therapy 
Prior and concomitant medications include any drug (investigational, prescription, or over-the-
counter) or biological product (such as vaccines, blood or blood components) including herbal 
remedies or preparations. All prior/concomitant medications taken or received by a subject 
within the 28 days prior to the Month 1-Day 1 Visit through the EOS/ETD Visit, and any 
changes to concomitant medications during the study, will be recorded in the appropriate eCRF. 
5.6.1 
Allowed Concomitant Medication/Therapy 
• Radiation therapy for the treatment of local amyloid deposits 
• Concomitant chemotherapy: 
o The Investigator may prescribe chemotherapy as per standard of care

o NEOD001 serum sample – within 2 hours before infusion – every 6 months (±1 month) 
o Anti-NEOD001 serum sample – preinfusion – every 3 months 
Study Drug Administration: 
Subjects who present with symptomatic orthostatic hypotension and/or systolic BP <85 mmHg, 
which in the medical judgment of the Investigator would interfere with the subject’s ability to 
safely receive treatment, will have study drug withheld until the next scheduled monthly 
administration, but should still have all other study visit assessments completed. If study drug is 
withheld and subsequently rescheduled, central laboratory assessments required for that visit will 
need to be repeated if they were drawn >7 days prior to the rescheduled dosing date. A symptom-
directed physical exam and vital signs need to be repeated prior to each dosing.  
• Month 1-Day 1: 
o Administer study drug IV over 60 (±10) minutes unless a longer infusion duration was 
established for the individual subject in Study NEOD001-201. See Section 5.3 for 
information on dosage, preparation, and administration of study drug. 
• All Other Months-Day 1: 
o If the Month 1-Day 1 infusion was well tolerated without infusion-associated AEs, 
administer NEOD001 IV over 60 (±10) minutes unless a longer infusion duration was 
established for the individual subject during Study NEOD001-201. See Section 5.3 for 
information on dosage, preparation, and administration of study drug; if needed, see 
Section 5.4 for dose adjustment instructions. 
Assessments After Infusion: 
• Monitor subjects per Section 5.3 following completion of the study drug infusion 
• Routine medications should not be administered for at least 15 minutes after the completion 
of the NEOD001 infusion and, if possible, should be delayed until completion of the 
postinfusion vital sign and ECG assessments

• When ECGs are scheduled to be performed at the same visit as PK blood collection, the ECG 
should be performed before the PK blood collection  
Concomitant Medications: 
• Routine medications should not be administered for at least 15 minutes after the completion 
of the NEOD001 infusion and, if possible, should be delayed until completion of the 
postinfusion vital sign and ECG assessments 
• For subject receiving chemotherapy, medications such as anti-emetics required for 
prophylaxis of emesis for the subsequent chemotherapy should be given after the ECG has 
been completed 
• If chemotherapy is administered on the same day as NEOD001, the chemotherapy must be 
administered after the NEOD001 observation period and postdose vital sign measurements 
6.5 
Methods of Assessment 
6.5.1 
Safety 
6.5.1.1 
Clinical Laboratory Evaluations 
A central laboratory will be used for analysis of hematology, chemistry (including amylase), 
PT/INR, PTT, cardiac biomarkers, sFLCs, serum IFE/PEP, urinalyses, and 24-hour urine 
collection for urine IFE/PEP and urine protein excretion. Local urine pregnancy testing will be 
conducted as shown in Table 1. A positive urine pregnancy test (local laboratory) is to be 
confirmed with a serum pregnancy test (central laboratory). Local pregnancy test results will be 
collected via an eCRF and in the clinical database. 
Local laboratory results may be obtained at the Investigator’s discretion for subject management 
when necessary for obtaining results on a more immediate basis. Local laboratory results should 
also be obtained and reviewed for a safety assessment prior to each administration of 
chemotherapy. Results will be reviewed prior to dosing at each month’s Day 1 visit to confirm 
that continued dosing is appropriate. Results from local laboratory tests (Exception: pregnancy 
tests) will not be collected via an eCRF or the clinical database. 
Other Coagulation Indices: Citrated plasma samples will be collected and frozen for potential 
analysis of coagulation indices at a later date. These analyses may include but may not be limited 
to the indices listed in Appendix 11.

24-hour Urine Collection: The 24-hour urine IFE/PEP and 24-hour urine protein excretion tests 
will be performed using the same 24-hour urine collection sample when required at the same 
visit. Details regarding the 24-hour urine sample collection will be provided in the Laboratory 
Manual. 
Bioanalytical Samples: A bioanalytical laboratory will be used for the analysis of serum 
NEOD001 and anti-NEOD001 samples (Sections 6.5.3 and 6.5.4). 
Details for the processing of laboratory specimens will be provided in the Laboratory Manual. 
6.5.1.2 
Vital Signs 
Predose vital signs should be assessed within 30 minutes before start of dosing. Vital signs 
should be measured after the subject has been at rest ≥5 minutes. Within a single visit, assess in 
the same position for all time points. 
Heart rate will be measured from the radial pulse counted manually or with an automatic BP 
monitor over at least 15 seconds and adjusted per minute.  
Blood pressure (systolic and diastolic) measurements should be taken from the same arm 
throughout the study using an automated BP monitor that uses an oscillometric method.  
Respiratory rate will be measured over at least 15 seconds and adjusted per minute. 
Body temperature can be measured using either oral or tympanic methods, but the method should 
be consistent throughout the study for a given subject. 
As part of the 6MWT, BP and HR will be collected pre- and post-6MWT administration. 
6.5.1.3 
Physical Examination 
Any unfavorable changes in physical examination findings considered by the Investigator as 
clinically significant will be documented on the eCRF as an AE. Other results of the physical 
examinations will not be collected via an eCRF or the clinical database. Physical examinations 
must be performed by the Investigator or a medically qualified delegate. 
A complete physical examination includes height (Screening only), weight, and examination of 
the following:  general appearance; head, ears, eyes, nose, and throat; neck; skin; cardiovascular 
system; respiratory system; gastrointestinal system; and nervous system. A directed physical 
examination includes weight and other components, which will be as clinically indicated. At all 
visits, the following are to be assessed: macroglossia, submandibular nodes/fullness, adenopathy, 
ecchymoses, liver/spleen size (palpable +/-), ascites (+/-), and edema (which should be 
quantified on a scale of 0-4+).

12-Lead ECGs 
The ECGs will be performed centrally. Measurements will be made in triplicate, 1 to 10 minutes 
apart and taken after the subject has rested in a supine position for ≥5 minutes. Heart rate, PQ/PR 
duration, QRS duration, QT duration, and QTcF - Fridericia's correction formula, and the 
Investigator’s overall interpretation will be recorded. Refer to Section 6.4 for details regarding 
order of assessments in relation to conducting 12-lead ECGs.

Study Manual. As part of the 6MWT, BP and HR will be collected pre- and post-6MWT 
administration. 
6.5.2.5 
Peripheral Neuropathy Assessment 
Peripheral neuropathy will be assessed as follows: 
• The Neuropathy Impairment Score in Lower Limbs (NIS-LL; Appendix 6) assesses lower 
limb reflexes, sensation, and motor strength and will be administered to subjects who had 
peripheral neuropathy in Study NEOD001-201 
• The Visual Analog Scale – Pain Intensity (VASPI; sample tool in Appendix 7) assesses a 
subject’s level of pain related to peripheral neuropathy and will be administered to subjects 
who had painful peripheral neuropathy in Study NEOD001-201. Details regarding 
administration of the VASPI are described in the Study Manual.  
Peripheral neuropathy and neuropathic pain AEs will be assessed using CTCAE grading, as 
shown in Table 2.

Pharmacokinetics 
All subjects enrolled in the study will undergo sparse sampling for serum NEOD001 according 
to Table 1 and the Laboratory Manual. Additional samples should be collected if a significant 
toxicity is observed (per Section 5.4.2). Serum NEOD001 concentrations from this study will be 
pooled with similar samples from other studies in a population PK analysis. Details will be 
provided in a separate document. Refer to the Laboratory Manual for additional details. 
6.5.4 
Immunogenicity 
Serum ADA levels will be measured according to Table 1 and the Laboratory Manual. 
Additional samples should be collected if a significant toxicity is observed (per Section 5.4.2). 
ADA levels will be correlated with serum NEOD001 concentrations when ADA and 
corresponding serum NEOD001 concentrations are available.  
An electrochemiluminescent (ECL) assay will be used to detect serum anti-NEOD001 
antibodies. Any screening positives will be run at increasing dilutions and a titer determined 
(expressed as the reciprocal of the dilution that generates a positive response). Additionally, all 
positives will be run in a confirmatory assay to determine the response is specific to NEOD001. 
Any sample found to be confirmed positive for anti-NEOD001 antibodies may be further 
evaluated by a neutralizing antibody (nAb) assay.

ADVERSE EVENTS/SERIOUS ADVERSE EVENTS AND REPORTING 
7.1 
Adverse Events—Definition 
An AE is any untoward medical occurrence associated with the use of a drug in humans, whether 
or not considered drug related. An AE can, therefore, be any unfavorable and unintended sign 
(including a laboratory finding, for example), symptom, syndrome, or disease temporally 
associated with the use of a medicinal product, whether or not considered related to the 
medicinal product. Examples include: 
• Any treatment-emergent signs and symptoms (events that are marked by a change from the 
subject’s baseline/entry status [e.g., an increase in severity or frequency of preexisting 
abnormality or disorder]) 
• All reactions from study drug, abuse of drug, withdrawal phenomena, sensitivity, or toxicity 
to study drug 
• Apparently unrelated illnesses 
• Injury or accidents 
• Exacerbations of the underlying disease (indication) 
• Extensions or exacerbations or symptomatology, subjective events reported by the subject, 
new clinically significant abnormalities in clinical laboratory, physiological testing, or 
physical examination 
The reporting period for AEs is from the time that the ICF is signed through 30 days after the last 
dose of study drug or last study visit, whichever is later. All AEs, whether or not related to the 
study drug, must be fully and completely documented on the eCRF and in the subject’s medical 
notes. The following attributes must be assigned:  description, dates of onset and resolution, 
severity, assessment of relatedness to study drug (either related or not related), and action taken. 
The Investigator may be asked to provide additional follow-up information. 
In the event that a subject is withdrawn from the study because of an AE, it must be recorded on 
the eCRF. The subject should be followed and treated by the Investigator until the AE has 
resolved, stabilized, or a new chronic baseline has been established. 
The Investigator must report all AEs. At each visit the Investigator will ask the subject a 
nonspecific question (e.g., “Have you noticed anything different since your last visit?”) to assess 
whether any AEs have been experienced since the last report or visit. Adverse events will be 
identified and documented on the eCRF in appropriate medical terminology. The severity and the 
relationship to the study drug will be determined and recorded on the eCRF (Sections 7.2 and 
7.3). 
Note that any intermittent or as-needed (“PRN”) use of medication (and specifically any newly 
prescribed medication) during the course of the study may indicate the occurrence of an AE that 
may need to be recorded in more than one eCRF.

7.2 
Adverse Events—Severity Rating 
Adverse events will be assessed according to CTCAE v4.0 (National Cancer Institute, 2009). 
Adverse events that do not have a corresponding CTCAE term will be assessed according to 
their impact on the participant’s ability to perform daily activities as listed below. The severity of 
each AE should be characterized and then classified into one of five clearly defined categories as 
follows: 
• Grade 1 (mild): Mild; asymptomatic or mild symptoms; clinical or diagnostic observations 
only; intervention not indicated. 
• Grade 2 (moderate): Moderate; minimal, local or noninvasive intervention indicated; 
limiting age-appropriate instrumental activity of daily living (e.g., preparing meals, shopping 
for groceries or clothes, using the telephone, managing money). 
• Grade 3 (severe): Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-care 
activities of daily living (e.g., bathing, dressing and undressing, feeding self, using the toilet, 
taking medications, and not bedridden). 
• Grade 4 (life threatening): Life-threatening consequences; urgent intervention indicated. 
• Grade 5 (fatal): Death related to AE. 
These five categories are based on the Investigator’s clinical judgment, which in turn depends on 
consideration of various factors such as the subject’s reports, the Investigator’s observations, and 
the Investigator’s prior experience. The severity of the AE should be recorded in the appropriate 
section of the eCRF. The evaluation of severity is distinguished from the evaluation of 
“seriousness.” A severe event might not meet the criteria for seriousness and a serious event 
might be evaluated as mild. For example, a subject might have a severe headache that does not 
require hospitalization and is consequently not serious; or a subject might have a mild 
myocardial infarction that requires hospitalization and is, therefore, serious. 
7.3 
Adverse Events—Causality Rating 
The causality of each AE should be assessed and classified by the Investigator as “related” or 
“not related.” An event is considered related if there is “a reasonable possibility” that the event 
may have been caused by the product under investigation (i.e., there are facts, evidence, or 
arguments to suggest possible causation). 
Guidelines for “Related” Events 
• There is clear evidence to suggest a causal relationship, and other possible contributing 
factors can be ruled out. 
• There is evidence to suggest a causal relationship, and the influence of other factors is 
unlikely. 

Study Drug: NEOD001 
CONFIDENTIAL 
Study Protocol: NEOD001-OLE251 
Original Protocol:  09 January 2017 
Page 63 of 100 
• There is some evidence to suggest a causal relationship (e.g., the event occurred within a 
reasonable time after administration of the study drug). However, the influence of other 
factors may have contributed to the event (e.g., the subject’s clinical condition, other 
concomitant events). 
Guidelines for “Not related” Events 
• There is little evidence to suggest there is a causal relationship. There is another reasonable 
explanation for the event. 
• An adverse event will be considered “not related” to the use of the product if any of the 
following tests are met: 
o An unreasonable temporal relationship between administration of the product and the 
onset on the AE (e.g., the event occurred either before, or too long after administration 
of the product for it to be considered product-related) 
o A causal relationship between the product and the AE is biologically implausible (e.g., 
death as a passenger in an automobile accident) 
o A clearly more likely alternative explanation for the AE is present (e.g., typical adverse 
reaction to a concomitant drug and/or typical disease-related event) 
Consider the Following When Assessing Causality 
• Temporal associations between the agent and the event 
• Effect of dechallenge and/or rechallenge 
• Compatibility with known class effect 
• Known effects of concomitant medications 
• Preexisting risk factors 
• A plausible mechanism 
• Concurrent illnesses 
7.4 
Serious Adverse Events and Unexpected Adverse Events 
In addition to the severity rating, each AE is to be classified by the Investigator as “serious” or 
“not serious.” The seriousness of an event is defined according to the applicable regulations and 
generally refers to the outcome of an event. An SAE is one that meets one or more of the 
following: 
• Is fatal 
• Is life-threatening 

Study Drug: NEOD001 
CONFIDENTIAL 
Study Protocol: NEOD001-OLE251 
Original Protocol:  09 January 2017 
Page 64 of 100 
• Is persistent or significantly incapacitating or causes substantial disruption of the ability to 
conduct normal life functions 
• Requires inpatient hospitalization 
• Prolongs existing hospitalization 
• Is a congenital anomaly or birth defect  
• Is an important medical event that may jeopardize the subject and/or may require medical or 
surgical intervention to prevent one of the outcomes listed above 
Definition of Life-threatening 
An AE or suspected adverse reaction is considered "life-threatening" if, in the view of either the 
Investigator or Sponsor (and/or designee), its occurrence places the subject at immediate risk of 
death. It does not include an AE or suspected adverse reaction that, had it occurred in a more 
severe form, might have caused death. 
Definition of Hospitalization 
Hospitalization is defined by the Sponsor as a full admission to the hospital for diagnosis and 
treatment. This includes prolongation of an existing inpatient hospitalization.  
Examples of visits to a hospital facility that do not meet the serious criteria for hospitalization 
include: 
• Emergency room visits that last for a period of <24 hours and do not result in a full hospital 
admission  
• Outpatient surgery 
• Preplanned or elective procedures (Section 7.4.1) 
• Protocol procedures 
The above events would not be reported as SAEs unless the event triggering the hospital visit is 
an SAE as defined by other SAE criteria such as life-threatening, results in persistent or 
significant disability/incapacity or as per medical judgment of the Investigator. 
Any other event fulfilling the definition of serious that develops as a result of the in-hospital 
procedure or extends the hospital stay is an SAE. 
Definition of Disability 
Disability is defined as a persistent or significant incapacity or substantial disruption of the 
ability to conduct normal life functions. 

Study Drug: NEOD001

Study Protocol: NEOD001-OLE251 
Original Protocol:  09 January 2017 
Page 65 of 100 
Definition of Medically Significant 
Important medical events (medically significant events) that may not result in death, be life-
threatening or require hospitalization may be considered to be an SAE when, based upon 
appropriate medical judgment, they may jeopardize the subject and/or may require medical or 
surgical intervention to prevent one of the outcomes listed in this definition. Examples of such 
events are a new diagnosis of cancer, intensive treatment in an emergency room or at home for 
allergic bronchospasm, or convulsions that do not result in hospitalization, or development of 
drug dependency or drug abuse. 
An SAE may also include any other event that the Investigator or Medical Monitor judges to be 
serious, or that suggests a significant hazard, contraindication, side effect, or precaution. 
Definition of Suspected Adverse Reactions 
Suspected adverse reaction is considered any AE for which there is a reasonable possibility that 
the drug caused the AE. 
Definition of Unexpected 
An AE or suspected adverse reaction is considered “unexpected” if it is not listed in the 
Investigator’s Brochure or is not listed at the specificity or severity that has been observed. 
“Unexpected,” as used in this definition, also refers to AEs or suspected adverse reactions that 
are mentioned in the Investigator’s Brochure as occurring with a class of drugs or as anticipated 
from the pharmacological properties of the drug, but are not specifically mentioned as occurring 
with the particular drug under investigation. 
7.4.1 
Elective Procedures and Surgeries 
For the purposes of this protocol, the following conventions will apply for SAE reporting of 
elective procedures, and surgeries: 
• A prescheduled elective procedure or a routinely scheduled treatment is not to be considered 
an SAE, even if the subject is hospitalized, provided the site stipulates that: 
o The condition requiring the prescheduled elective procedure or routinely scheduled 
treatment was present before and did not worsen or progress between the subject’s 
consent to participate in the clinical trial and the time of the procedure or treatment 
o The prescheduled elective procedure or routinely scheduled treatment is the sole reason 
for admission and intervention 
• An untoward medical event occurring during the prescheduled elective procedure or 
routinely scheduled treatment should be recorded as an AE or a SAE. Any concurrent 
medications should also be recorded on the eCRF.

7.4.2 
Other Reportable Information 
In addition, and for the purposes of monitoring, any occurrence of exposure through lactation 
and any pregnancy (with or without an AE) of a female subject or partner of a male subject 
should be reported, regardless of seriousness, according to the directions in Section 7.4.4. Any 
subject who becomes pregnant during the study must be withdrawn from study drug treatment, 
and will be followed to term. 
7.4.3 
Disease Progression and Death 
Disease progression (including progression of hematologic condition and/or organ dysfunction of 
AL amyloidosis, and death due to disease progression) is generally recorded as part of the 
efficacy evaluation and should not be reported as a specific AE or SAE term. When an AE 
resulting from disease progression meets the requirements to be considered serious, the SAE 
verbatim term should be reported as the diagnosis that best describes the event rather than as 
“disease progression.” For instance, a subject with pleural effusion presents with shortness of 
breath. The cause of the shortness of breath is a pleural effusion resulting from disease 
progression. The event term may be reported as “pleural effusion” instead of disease progression.  
Death should not be reported as an SAE term, but as a clinical outcome of a specific SAE. The 
cause of death, reported on a source document such as the Death Certificate or autopsy report, 
should be used as the event term for the SAE. For example, in a subject with acute heart failure 
that results in death, the SAE is reported as “acute heart failure” with an outcome of “death.”  
7.4.4 
Serious Adverse Events—Reporting 
It is the responsibility of the Investigator to report SAEs to the Sponsor or its designee within 
24 hours of awareness of the event or safety information, whether initial or follow-up. 
All SAEs must be reported immediately (within 24 hours of awareness) to the Sponsor or its 
designee (see Study Manual for details). Do not delay in the reporting of a suspected SAE in 
order to obtain additional information. Any additional information, if collected, can be reported 
to the Sponsor or its designee as a follow-up to the initial report. SAEs will be reported using the 
SAE forms provided as part of the Study Manual. Please remember to give details of the subject 
identification number or other appropriate terminology and ensure the narrative is 
comprehensive and includes a chronology and assessment of the event. 
Reporting of SAEs to the Institutional Review Board/Institutional Ethics Committee (IRB/IEC) 
will be done in compliance with the standard operating procedures and policies of the IRB/IEC 
and with applicable regulatory requirements. Adequate information must be obtained by the 
Sponsor or its designee showing that the IRB/IEC was properly and promptly notified as 
required. Please refer to the Study Manual for details on reporting SAEs. 
The Investigator is encouraged to discuss any AEs with the Sponsor Medical Monitor for which 
the issue of seriousness is unclear or questioned. Contact information for the Medical Monitor is 
listed on the Team Roster in the Study Manual.

The reporting period for SAEs is the period from signing of the ICF through 30 days after the 
last administration of study drug or last study visit, whichever is later. SAEs reported to the 
Investigator outside of this reporting period will be reported to the Sponsor or its designee only 
if, in the judgment of the Investigator, there is “a reasonable possibility” that the event may have 
been caused by the product.  
All SAEs will continue to be followed until the end of the study or until such events have 
resolved or the Investigator, in conjunction with the Sponsor or its designee, deems them to be 
chronic or stable.

STATISTICAL METHODS AND CONSIDERATIONS 
A statistical analysis plan, providing details about the specific planned analyses and hypothesis 
tests, will be prepared and approved by the Sponsor prior to study database lock.  
Endpoints are listed in Section 3.2. 
8.1 
Analysis Populations 
All analyses will be based on the Safety Population, defined as all subjects who receive any 
amount of study drug. 
Select analyses will use efficacy subsets, defined as: 
• Renal Evaluable Population: subjects who had renal involvement in Study NEOD001-201  
• Peripheral Neuropathy Evaluable Population: subjects who had peripheral nerve involvement 
in Study NEOD001-201 
• Hepatic Evaluable Population: subjects who had hepatic involvement in Study NEOD001-
201 
8.2 
Analysis of Study Population and Subject Characteristics 
Enrollment, important protocol violations, and discontinuations from the study will be 
summarized. 
Demographic and baseline characteristics, such as age, sex, race, weight, and markers of organ 
function at Screening will be summarized using means, standard deviations, medians, ranges for 
continuous variables, and proportions for categorical variables.  
Study drug administration data will be listed by study site, subject number, and visit; and any 
dose modifications will be flagged. Means and standard deviations will be used to summarize the 
total dose of NEOD001 received.  
8.3 
Analysis of Safety Endpoints 
Safety will be assessed through changes in vital signs, 12-lead ECGs, laboratory test results, and 
summaries of AEs. All TEAEs and SAEs will be summarized.  
Quantitative laboratory tests will be assigned toxicity grades based on CTCAE v4.0. Shifts in 
CTCAE toxicity grade of laboratory tests will be presented from baseline to worst value, last 
value, and at each postbaseline visit. Summaries will present the number and percentage of 
subjects with shifts in laboratory toxicity grade. 
Descriptive statistics of the quantitative laboratory, vital sign, and ECG parameters will be 
presented by study visit, as well as the change from baseline.

8.4 
Analysis of Efficacy Endpoints 
Response rates will be summarized including 95% confidence intervals. The distributions of 
time-to-event endpoints (progression-free survival, overall survival) will be summarized using 
the Kaplan-Meier method.  
All quantitative endpoints (except 6MWT distance) defined as the change from baseline will be 
analyzed using linear mixed models for repeated measurements (MMRM). The dependent 
variable will be the change from baseline at each time point. The model will include fixed effects 
for time point and treatment-by-time interaction. The baseline value of the corresponding 
endpoint will be included as a covariate and the unstructured covariance model will be used. The 
denominator degrees of freedom will be estimated using the Kenward-Roger approximation. The 
6MWT distance change from baseline will be analyzed using a Wilcoxon signed rank test. 
8.5 
Analysis of Other Endpoints 
8.5.1 
Pharmacokinetics 
Serum NEOD001 concentrations (sparse sampling) will be pooled with similar samples from 
other studies in a population PK analysis. Details will be provided in a separate document. 
8.5.2 
Immunogenicity 
Serum anti-NEOD001 titers will be listed and correlated with clinical toxicity and serum 
NEOD001 concentrations (where available). Anti-NEOD001 antibody levels will be correlated 
with NEOD001 exposure level to assess potential dose concentration related associations when 
anti-NEOD001 antibody and corresponding PK data are available. 
8.6 
Determination of Sample Size 
Not applicable as this is an open-label extension study for subjects who completed 
Study NEOD001-201. 
8.7 
Handling of Dropouts and Missing Data 
Observed data will be included in listings and summary tables. Sensitivity analyses imputing 
missing data may be conducted.

DATA RECORDING, RETENTION, AND MONITORING 
9.1 
Case Report Forms 
The clinical site(s) participating in this study is (are) required to submit clinical data for each 
screened subject via an electronic data capture (EDC) system, using an eCRF. Site personnel will 
be trained on the EDC system before receiving access to the system. The Sponsor or its designee 
is responsible for maintaining a record of all system users. The participants of the study will not 
be identified by name on any study documents to be collected by the Sponsor. 
All clinical information requested in this protocol will be recorded on the eCRFs provided by the 
Sponsor or its designee (or via other data collection methods, e.g., electronic laboratory data 
transfer). The Investigator is responsible for reviewing all eCRFs, verifying them for accuracy, 
and approving them via an electronic signature. An electronic copy of the completed eCRFs will 
be sent to the Investigator’s site at the completion of the study. 
9.2 
Availability and Retention of Records 
The Investigator must make study data accessible to the Sponsor, Study Monitor, other 
authorized representatives of the Sponsor and CA inspectors upon request. A file for each subject 
must be maintained at the clinical site that includes the signed ICF and the Investigator’s copies 
of all source documentation related to that subject. The Investigator must ensure the reliability 
and availability of source documents from which the information on the eCRF was derived. 
Investigators are required to maintain all study documentation, including documents created or 
modified in electronic format, for at least 15 years following the completion of the study unless 
local regulations or institutional policies require a longer retention period or the Investigator is 
otherwise notified in writing by the Sponsor. Essential documents should be retained until at 
least 2 years after the last approval of a marketing application in an International Council for 
Harmonisation (ICH) region and until there are no pending or contemplated marketing 
applications in an ICH region or at least 2 years have elapsed since the formal discontinuation of 
clinical development of the investigational product. These documents should be retained for a 
longer period, however, if required by the applicable regulatory requirements or by an agreement 
with the Sponsor. The Investigator must not discard any records unless given written 
authorization by the Sponsor. 
Subject identity information will be maintained for 15 years unless applicable law or regulation 
requires a longer period. 
9.3 
Quality Control and Quality Assurance 
Sponsor representatives and CA inspectors are responsible for contacting and visiting the 
Investigator for the purpose of inspecting the facilities and, upon request, inspecting the various 
records of the study (e.g., eCRFs and other pertinent data), provided that subject confidentiality 
is respected. 

Study Drug: NEOD001

The Study Monitor is responsible for inspecting the eCRFs at regular intervals throughout the 
study to verify the following:  adherence to the protocol; completeness, accuracy, and 
consistency of the data; and adherence to local regulations on the conduct of clinical research. 
The Monitor should have access to subject medical records and other study-related records 
needed to verify the entries on the eCRFs. The Investigator must agree to cooperate with the 
Monitor to ensure that any problems detected in the course of these monitoring visits are 
resolved. 
In accordance with ICH GCP and the Sponsor’s (or its designee’s) audit plans, this study may be 
selected for an audit. Inspection of site facilities (e.g., pharmacy, drug storage areas, laboratories, 
etc.) and review of study-related records may occur in order to evaluate the trial conduct and 
compliance with the protocol, ICH GCP, and applicable regulatory requirements. 
9.4 
Subject Confidentiality 
The Investigator must ensure that each subject’s anonymity is maintained as described below. On 
the eCRFs or other documents submitted to the Sponsor or its designee, subjects must be 
identified by no more than their date of birth or age, sex, and study-specific site and subject 
numbers. Documents that are not for submission to the Sponsor (e.g., signed ICFs) should be 
kept in strict confidence by the Investigator in compliance with applicable regulations and ICH 
GCP Guidelines. The Investigator and institution must permit authorized representatives of the 
Sponsor, IRB/IEC, or CA direct access to review the subject’s original medical records for 
verification of study-related procedures and data. Direct access includes examining, analyzing, 
verifying, and reproducing any records and reports that are needed for the evaluation of the 
study. The Investigator is obligated to inform the subject in the ICF that the above named 
representatives may review study-related records from subjects.

Appendix 2 
Examples of Highly Effective Contraception Methods 
Contraception methods that can achieve a failure rate of <1% per year when used consistently 
and correctly are considered to be highly effective. Such methods include: 
• Combined (estrogen and progestogen containing) hormonal contraception associated with 
inhibition of ovulation1: 
o Oral 
o Intravaginal 
o Transdermal 
• Progestogen-only hormonal contraception associated with inhibition of ovulation1: 
o Oral 
o Injectable 
o Implantable2 
• Intrauterine device (IUD)2 
• Intrauterine hormone-releasing system (IUS)2 
• Bilateral tubal occlusion2 
• Vasectomised partner2,3 
• Sexual abstinence4 
 
1  
Hormonal contraception may be susceptible to interaction with the Investigational Medicinal Product (IMP), 
which may reduce the efficacy of the contraception method. 
2  
Contraception methods that in the context of this guidance are considered to have low user dependency. 
3 
Vasectomised partner is a highly effective birth control method provided that partner is the sole sexual partner 
of the women of childbearing potential (WOCBP) trial participant and that the vasectomised partner has 
received medical assessment of the surgical success. 
4  
In the context of this guidance sexual abstinence is considered a highly effective method only if defined as 
refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. 
The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the 
preferred and usual lifestyle of the subject.
