Title of Study 
NOX66 and Palliative Radiotherapy in Patients with Late-Stage Prostate Cancer 
– a Phase 1b Proof of Concept and dose confirmatory study. 
Study Number 
NOX66-002A 
Development phase 
Phase Ib 
Name of Active Ingredient  
Idronoxil 
Description of 
Investigational product 
NOX66 is idronoxil in a hydrogenated lipophilic base formulated as a 
suppository, designed to protect idronoxil from Phase 2 metabolism. 
Mode of Administration 
and dosage 
NOX66 will be self-administered as a rectal suppository. Patients will be 
instructed in the procedure of suppository administration  
Dosage is 1, 2 or 3 suppositories (idronoxil dosage 400mg, 800mg or 1200mg) 
for 13 (+3) consecutive days.  
Number of subjects 
planned 
Up to 24 patients in 3 idronoxil dose level cohorts of 4 patients (n=12) and an 
expansion cohort of 12 patients. 
Indication / Patient 
Population 
Metastatic castrate-resistant prostate cancer with no remaining standard 
treatment options. Patients must have at least one metastatic lesion which is 
amenable to RT. 
Study period and duration 
of treatment 
The study will comprise two parts:  
1. Treatment and follow up (24 weeks) comprising: 
• NOX66 (Day 1-16) 
• Palliative Dose Radiation therapy (Day 2-9) 
• 6-week follow up 
• 12-week follow up 
• 24-week follow up 
2. Long term follow-up: 
• Ongoing follow up and monitoring of patient to assess long term 
effects of NOX66 administration and survival including scheduled 
follow up at 9 ,12, 15, 18, 21 & 24 months from treatment 
commencement date.  
Primary study objective 
• To determine the tolerability and toxicity of NOX66 administered in 
conjunction with palliative radiation therapy 
Secondary study objectives 
• To observe any clinical response to treatment of NOX66 in combination 
with palliative radiation therapy 
• To observe the effects of NOX66 use on long term (24 months) outcomes 
for patients

• To document Progression Free Survival (PFS) and Overall Survival (OS) of 
patients 
• Exploratory:  to measure levels of idronoxil  
Methodology 
Patients will have a minimum of one (1) lesion which is amenable to radiation 
therapy and be treated in combination with idronoxil (NOX66).  
The Study will involve 13-16 days of treatment with NOX66 and radiation 
therapy as follows: 
• Baseline: Tumour assessment scan using CT/MRI, screening laboratory 
assessments (including PSA levels), and pain assessment (Brief pain 
Inventory-Short Form) 
• Day 1-16: NOX66 will be administered rectally (one, two or three 
suppositories daily, depending on cohort allocation) 
• Day 2-9: Lesions selected for irradiation will receive palliative dose (20Gy) 
radiation therapy in 5 fractionated doses over 7 days. 
• Week 6: Initial follow up scan using CT/MRI, follow up laboratory 
assessments (including PSA levels), and pain assessment 
• Week 12: Second follow up scan using CT/MRI, follow up laboratory 
assessments (including PSA levels), and pain assessment 
• Week 24: third follow up scan using CT/MRI, follow up laboratory 
assessments (including PSA levels), and pain assessment 
• Month 9 (3 months after Week 24): Performance Status (ECOG), scan 
using CT/MRI/US, PSA measure and pain assessment. 
• Month 12: Performance Status ECOG), scan using CT/MRI, PSA measure 
and pain assessment. 
• Month 15, 18, 21 & 24 (every 3 months after Month 12 follow up visit for 
another 12 months): Scan using CT/MRI/US & PSA measure. 
Patients will continue to be followed up after 24 months at the discretion of 
the investigator. 
The study steering committee (SSC) will review emerging safety data and 
determine the dose cohort escalation following end of treatment cycle of final 
patient in a cohort. Following interim analyses of safety data and tumour 
response at WEEK 6 of 3 dose cohorts of 12 total patients, the SSC will inform 
on dose for cohort expansion of additional 12 patients. 
Baseline CT/MRI scans shall be assessed and any lesions which can be 
measured in accordance with RECIST criteria will be noted as “target lesions”. 
Target measurable lesions may either be at the site of irradiation or non-
irradiated. Patients with identified measurable target lesions will be assessed 
for objective response using RECISTv1.1 criteria. All patients will have 
radiological scans, PSA, ECOG and pain scores assessed for clinical response by 
a Radiation Oncology Expert Committee. 
Criteria for Evaluation 
Safety: assessed through the analysis of routine clinical and laboratory 
assessments 
of 
haematology 
and 
chemistry 
parameters, 
physical

examinations and vital signs. Adverse event monitoring will be performed and 
assessed using the National Cancer Institute Common Terminology Criteria for 
Adverse Events, Version 4.03 (CTCAE) scoring system. 
Efficacy: Overall response will be assessed by a Radiation Oncology Expert 
Committee based on change from baseline of tumours on imaging data by 
RECISTv1.1 criteria for measurable lesions, total pain score, PSA and ECOG 
score. 
Biomarkers: Serum levels of PSA will be measured at baseline and four-time 
points (end of Treatment Cycle (Day 16), at Week 6 ,12 and 24 post therapy. 
Plasma levels of idronoxil will be measured at baseline and two post therapy 
time points, end of Treatment Cycle (Day 16) and at Week 6. 
 
Statistical methods 
No statistical analysis of results will be conducted due to the size of the cohort. 
Primary endpoint will be reported as the number of patients experiencing 
toxicity >2 and dose limiting toxicities (DLT) with description of the toxicity.  
Secondary endpoints will be reported as the response (measured and 
observed) to treatment of each patient over the 24-week initial period. Data 
will be presented in table form, with adverse events and outcomes listed per 
patient. 
Overall and progression-free survival, PSA and pain scores collected during the 
extended follow-up period will be summarized in the same manner as for the 
immediate post-treatment follow-up period. 
A detailed Statistical Analysis Plan will be developed and approved prior to 
data lock.

4 INTRODUCTION 
The mainstays of oncology therapy – chemotherapy and radiation therapy – provide varying 
degrees of efficacy in patients with cancer, and for those with late stage metastatic disease 
the prognosis for patients can be very poor. A primary reason for these poor outcomes is the 
presence of chemo- and radio-resistance mechanisms in tumour cells.1 This resistance leads 
to higher doses of chemotherapy and/or radiation therapy being required, to a point where 
the adverse effects (toxicity) of therapy outweighing the benefits, or that treatment no longer 
provides any benefit for patients. Finding a treatment that can overcome some or all of these 
resistance mechanisms may lead to: 
• Providing therapy with clinically meaningful outcomes for patients with end stage and 
late stage cancers  
• Improving clinical outcomes for patients undergoing established chemotherapy and 
radiation therapy treatment 
• Allowing lower doses of chemotherapy and radiation therapy to be used in future 
treatment of patients, providing similar efficacy outcomes while minimizing toxicity – 
providing treatment for patients who may otherwise not receive treatment (e.g. frail 
and elderly patients) 
This study will investigate the use of NOX66 - idronoxil formulated in a lipophilic base – in 
combination with palliative radiation therapy, in patients with end stage castrate resistant 
prostate cancer. The data generated, in conjunction with other early phase studies, will be 
used to inform the development of larger studies to investigate the efficacy and safety of 
NOX66 (idronoxil) in combination with radiation therapy and chemotherapy. 
The key hypotheses to be tested in this study are: 
a. That idronoxil can be safely added to palliative dose radiation therapy. 
b. That idronoxil, via its selective inhibition of PI3K/Akt signalling in tumour cells, 
may sensitise tumours to palliative doses of radiation therapy, with efficacy 
signals being seen in this study.  
c. That any efficacy seen in irradiated tumours may lead to an effect on non-
irradiated tumours. 
Furthermore, this study will investigate three doses of NOX66 to determine if there is any 
difference in safety and / or efficacy signals with increasing dose and to determine the optimal 
dose for future radiation therapy combination studies.  
 
4.1 MULTI-DRUG RESISTANCE, CHEMO- AND RADIO-SENSITISATION AND 
IDRONOXIL 
Tumour cells develop a variety of mechanisms to avoid the effects of anti-cancer drugs. The 
term multi-drug resistance (MDR) refers to the typical situation where resistance to 

NOXOPHARM LIMITED

Protocol NOX66-002A 
Version 5.1, 11 July 2019  
 
Page 16 of 64 
treatment extends to most, if not all, chemotherapy drugs and treatment regimens. Some 
tumour cells display MDR from the outset (inherent resistance), while others develop it 
following exposure to chemotherapy (acquired resistance). Both forms of resistance are 
based on the same MDR mechanisms. 
A range of mechanisms are involved in MDR including: altered membrane transport, 
enhanced DNA repair, alteration of target proteins, activation of alternate signalling 
pathways, enzymatic digestion of drug, blockage of apoptosis, up-regulation of tumour-
promoter genes and down-regulation of tumour-suppressor genes.1-4 Of these, enhanced 
DNA repair also is an important mechanism in the resistance of tumour cells to radiation 
therapy.5,6 
Linking these various functions are a small number of upstream pro-survival pathways, 
particularly those regulated by phosphoinositide 3-kinase (PI3K), the serine/threonine kinase 
Akt, and the anti-apoptotic pathway NF-kB, all of which are over-expressed in many forms of 
cancer.6,7 
The key role of the PI3K/Akt/NF-kB signalling pathways in chemo- and radio-resistance 
mechanisms has marked them as key targets for drug development. These pathways, 
however, have an essential role in the survival of all cells, cancerous or otherwise6 - a 
fundamental that has blocked the successful development of any drug to target this pathway 
and provide selective targeting of cancer cells. The mechanism of action of idronoxil may 
overcome this barrier.  
Idronoxil is a small molecule synthetic derivative of the naturally-occurring isoflavone, 
genistein. Genistein has been shown to sensitise a range of solid cancer cells to both 
chemotherapy and radiation therapy, via both direct inhibitory effects on signal transduction 
and indirectly by genomic effects.8-11 Idronoxil has been specifically developed to enhance the 
anti-cancer properties observed with genistein by reducing the level of Phase 1 metabolism 
(and consequent loss of bio-activity) – leading to activity 10-30 times greater.12 
The mechanism of action of idronoxil means that it can selectively inhibit cancer cell PI3K/Akt 
pathways without affecting non-cancer cells. It does this by targeting an upstream regulator 
of PI3K/Akt which is expressed differently in cancer cells. Inhibition by idronoxil of this 
upstream target deprives the tumour cell of its key pro-survival signalling pathways, leading 
to down-regulation of PI3K/Akt. 
 
4.2 IDRONOXIL – A SELECTIVE INHIBITOR OF PI3K/AKT 
Idronoxil, also known as phenoxodiol, is a first-in-class, selective PI3K/Akt inhibitor. Details of 
the pharmacology of idronoxil are found the current version of the NOX66 Investigator’s 
Brochure. 
The primary target of idronoxil is external membrane NADH oxidase Type 2 (ENOX2). ENOX 
enzymes are located on the external membrane of cells and by regulating the movement of

Page 17 of 64 
electrons (protons) across the plasma membrane are responsible for maintaining the 
transmembrane electron potential.13 
Human cells have the capacity to express two forms of ENOX known as ENOX1 and its splice 
variant, ENOX2. ENOX1 is the constitutive form expressed by healthy cells while current 
literature suggests that ENOX2 is the active form of the ENOX enzyme in all cancer cells. 
Idronoxil binds to the motif that distinguishes ENOX2 from ENOX1, but has no binding affinity 
to ENOX1.14  
Inhibition of ENOX2 leads to an accumulation of protons within the plasma membrane of the 
cancer cell, creating a cascade of events involving the inhibition of a variety of downstream 
pro-survival pathways as described in Section 5.3. Because idronoxil selectively binds to 
ENOX2, with no binding affinity for ENOX1, only the cells expressing ENOX2 (i.e. tumour cells) 
are affected by idronoxil.15 
 
4.3 IDRONOXIL – SUMMARY OF MECHANISM OF ACTION 
The mechanism of action of idronoxil is summarized below, in Figure 1.  
 
Figure 1 Sequence of biochemical events following binding of idronoxil to ENOX2.  
The cascade of events is as follows:13-16 
1. Idronoxil binds to ENOX2, leading to inhibition of the trans membrane electron pump 
which, in turn, leads to an accumulation of proton ions within the plasma membrane.

2. Accumulation of protons disrupts sphingomyelin pathway with blockage of ceramide 
conversion to sphingosine-1-phosphate (S1P) – leading to a decrease in S1P and an 
increase in Ceramide within the plasma membrane.  
3. Decrease of S1P leads to a reduction in PI3K, AKT and XIAP and an increase in Caspase 
2.  
4. Reduction in AKT leads to reduction in NF-kB and allows up regulation of the intrinsic 
(mitochondrial) pathway of apoptosis, via an increase in Caspase 9 and Caspase 3, 
leading to cell death.   
5. Reduction in AKT also results in an inhibition of FLIP resulting in an increase in Caspase 
8 (activated via the Death Receptor on the Protein Membrane) – leading directly and 
indirectly (via the intrinsic pathway) to an increase in Caspase 3 and apoptosis. 
6. Reduction in XIAP prevents down regulation of Caspase 9 and Caspase 3, supporting 
apoptosis. 
Both in vitro and in vivo, idronoxil provides high levels of synergistic cytotoxicity with a wide 
range of chemotoxic (cisplatin, carboplatin, paclitaxel, gemcitabine, doxorubicin) and 
chemostatic (topotecan) drugs across a broad range of cancer phenotypes.17-19 
Where the terms chemo-sensitisation and radio-sensitisation often are used in the sense of 
priming cells to undergo greater drug- or radiation-induced damage, idronoxil (as used in this 
study) acts to block the ability of tumour cells to repair and recover from damage caused by 
chemotherapy and radiation therapy. 
 
4.4 IDRONOXIL – INTRAVENOUS AND ORAL DOSAGE FORMULATION 
Following pre-clinical development, Idronoxil commenced a clinical development program in 
2000, for intravenous (IV) and oral administration. Between 2000 and 2009 a series of phase 
1 and phase 2 studies were conducted, with a multi-centre Phase 3 trial commenced to 
investigate oral idronoxil as a chemo-sensitiser of carboplatin in late-stage, chemo-refractory 
ovarian cancer cases.20 Over 400 patients with late-stage cancer were treated in Phase 1, 2 
and 3 clinical studies.21 The clinical development program was stopped during the phase 3 
program due to slow recruitment into the pivotal trial and no difference in efficacy between 
the treatment arms. Further information regarding previous studies is contained in the 
current NOX66 Investigator’s Brochure. 
 
4.5 IDRONOXIL – NOX66 DOSAGE FORMULATION 
The lack of efficacy observed in the Phase 2 and 3 trials of oral idronoxil with carboplatin has 
been attributed to a high level (> 99%) of metabolism. Idronoxil undergoes Phase 2 
metabolism within the body, whereby water-insoluble compounds are converted into more

water-soluble forms through the action of transferase enzymes (present in gut mucosa and 
liver). This is achieved by attaching a glucuronide or sulphate chemical group. The resulting 
water-soluble drug conjugate is biologically inactive, with reactivation requiring enzymatic 
digestion by glucuronidases and sulphatases present in the lysosomes of target cells. Many 
phenolic drugs undergo this process including aspirin, codeine, paracetamol, naloxone, 
propofol and steroid hormones. 
Most normal cells contain high levels of glucuronidases and sulphatases, accounting for the 
biological activity of other phenolic drugs. Recent studies, however, suggest that cancer cells 
amend or inhibit this function as one of their multi-drug resistance mechanisms. Breast cancer 
cells, for example, have been found to contain negligible levels of deconjugating enzymes,22 
while some other forms of cancer undertake their own Phase 2 (transferase) metabolism.23   
NOX66 is a suppository dosage form of idronoxil, formulated in a hydrogenated lipophilic base 
and developed specifically to reduce the exposure of the drug to Phase 2 metabolism. Rectal 
absorption is a standard method of drug administration where Phase 2 metabolism is sought 
to be minimized, with venous drainage from the distal part of the rectum feeding into the 
inferior vena cava, thereby avoiding first pass liver metabolism. The lining of the rectum also 
is largely devoid of transferase activity.24-26   
Rat studies conducted by Noxopharm27 have suggested that when administered rectally in the 
form of NOX66: 
• idronoxil is readily bioavailable  
• the degree of Phase 2 metabolism is reduced  
• the drug readily distributes within tissues 
• is excreted primarily via the urine 
• administered drug is largely eliminated within 24 hrs, with no evidence of 
accumulation. 
 
4.6 NOX66 – CURRENT DRUG DEVELOPMENT PROGRAM 
This study forms part of a program of phase 1 studies designed to provide insight in to the 
safety and signals for efficacy of NOX66 in various cancer therapy settings, namely: 
- 
Safety and PK of NOX66 as monotherapy 
- 
NOX66 in combination with chemotherapy alone 
- 
NOX66 in combination with palliative radiation therapy alone, and the effects on 
tumours externally targeted with radiation 
- 
NOX66 in combination with palliative radiation therapy alone, and the effects on 
tumours not targeted with radiation therapy 
- 
NOX66 in combination with radiation therapy alone, with radiation therapy being 
administered as brachytherapy (internal targeting of treatment) 
- 
NOX66 in combination with chemotherapy and palliative radiation therapy

5 STUDY RATIONALE 
5.1 RATIONALE FOR COMBINATION WITH RADIATION THERAPY 
5.1.1 Radio-sensitisation 
Many cancer patients receive radiation therapy, either as part of a treatment regimen or in 
the palliative setting, to reduce tumour size and manage pain and symptoms associated with 
end stage cancer.28  
The anti-cancer effect of ionizing radiation relates to its ability to cause double strand breaks 
in DNA, and the non-specificity of this effect means that the dosage of radiation able to be 
applied is self-limiting. This dosage limitation is exacerbated by the presence of factors (radio-
resistance) that render some cancer cells less sensitive to the damaging effects of ionizing 
radiation, while normal cells are without those same factors and retain full radio-sensitivity, 
as discussed in Section 5.1. 
The use of NOX66 as a tumour cell-specific sensitiser of radiation therapy may provide greater 
response to targeted radiation therapy within the tumour cells, with the tumour specific 
nature of NOX66 activity leading to no greater effect on non-tumour cells. As such, NOX66 is 
expected to increase the response to palliative dose radiation therapy, reducing target 
tumour size beyond those expected with palliative radiation therapy alone, with no significant 
increase in serious and severe adverse events. 
5.1.2 Abscopal Response 
An abscopal (from Latin ab-scopus, away from the target) response describes tumour 
regression at sites distant to an irradiated field, and is a rare event seen in patients with 
various types of metastatic tumours receiving palliative radiation therapy to a single 
metastasis. First described29 over 50 years ago, the response is sufficiently rare to warrant 
clinical reports of individual cases, with responses in melanoma, lung cancer, kidney cancer 
and cutaneous lymphomas variously reported.30-33 
In the only prospective clinical study34 reported to date, 41 patients with metastatic solid 
cancers were treated with a combination of standard cytotoxic chemotherapy, external beam 
RT, and granulocyte-macrophage colony stimulating factor (GM-CSF). A maximum 2 lesions 
were irradiated (35 Gy in 10 fractionated doses) and the response measured by CT scan in 
both irradiated and non-irradiated lesions. An abscopal response was reported in 11/41 (27%) 
patients (4 lung cancer, 5 breast cancer, 2 thymic cancer). Two of these cases had a complete 
response (lung cancer) and 9 had a partial response. The median overall survival was 21 
months for abscopal responders versus 8 months for the non-responders.  
While the mechanism underlying this phenomenon is unknown, the results of the above 
study, in conjunction with a range of pre-clinical studies, points to the involvement of soluble 
signalling factors including tumour antigens that are hypothesized to be released by the dying 
irradiated tumour cells to mediate an immune response against non-irradiated lesions.35,36,37

Page 21 of 64 
In addition to its anti-cancer effects, idronoxil also has confirmed immune-stimulatory 
effects.38 Human peripheral blood CD56+ natural killer (NK) cells show increased lytic activity 
against K562 (myelogenous leukaemia cell line) in the presence of idronoxil. Also, in a mouse 
colon cancer (CT-26) model in which idronoxil monotherapy produced a significant anti-
cancer effect, ex vivo studies showed that idronoxil activated both NK and tumour-specific 
tumour cell lysis. As such, it is hypothesized that NOX66 may produce an abscopal effect in 
treating non-irradiated lesions when combined with radiation therapy. 
In this study, we will also monitor for any changes in non-irradiated lesions, to determine if 
NOX66 may induce an abscopal response when combined with radiation therapy. 
 
5.2 RATIONALE FOR DOSE OF NOX66 
Pre-clinical studies in mice consistently found an effective chemo-sensitising (standard 
cytotoxic drugs) dose of idronoxil to be between 100-150 mg/kg.12 Phase 2 metabolism in 
these models was observed to be significant, with 10-30% of idronoxil remaining as free drug 
and the remainder being excreted as the conjugated (inactive) metabolites. As such, an 
effective dose in rats of 20mg/kg free idronoxil has been used. This converts to an equivalent 
human dose of 3-4mg/kg, based on body surface area. Dosing in line with this was used for 
the intravenous and oral dosage formulations of idronoxil, with a dose of 1200mg being used 
for the Phase 3 oral study (Refer to Investigators’ Brochure for further information) 
Whilst the oral dose of idronoxil was found to be ineffective to due Phase 2 metabolism, these 
studies do show that idronoxil has minimal effect on non-tumour cells (in which 
deconjugation does occur and therefore the cells are exposed to active idronoxil). As such, 
doses in line with the oral dosing regimen have been selected for this and other phase 1 
studies. NOX66 has been developed to protect idronoxil from complete Phase 2 metabolism, 
enabling the active ingredient to target tumour cells and, in the case of this study, sensitise 
the target tumours to radiation therapy. 
While idronoxil displays significant anti-cancer effect in animals as a monotherapy,12,39 the 
applicants believe that its potential clinical use lies in its sensitizing abilities, which requires 
having the drug present in the tumour cell during the period of induction of the cytotoxic 
damage and the repairing process of that damage. 
 
5.3 POTENTIAL RISKS 
As with all products and formulations in Phase 1 development, the adverse event profile of 
idronoxil in the formulation of NOX66 has not been fully established.  
In vitro studies have shown no binding affinity for idronoxil to healthy human cells and, as 
such, minimal adverse events directly due to idronoxil are expected. This has been supported 

NOXOPHARM LIMITED

Page 22 of 64 
by the clinical research program of IV and oral formulations of idronoxil, where no adverse 
events of toxicity Grade 2 or higher have been reported.  
It is expected that any adverse events observed in the study will be due to the use of the 
combination of NOX66 with palliative radiation therapy. Any adverse events greater than 
normally observed with this therapy in the patient group for this study (e.g. fatigue at level 
greater than Grade 2) are expected to be related to a greater efficacy of the treatment (due 
to the sensitizing effect of NOX66). 
 
5.4 POTENTIAL BENEFITS 
As a Phase 1 sighting Study, the efficacy (benefits) of combining palliative radiation therapy 
and idronoxil (NOX66) is not known. The hypothesis, however, is that the effect of idronoxil 
in sensitizing the cancer cells to radiation therapy will provide an enhanced response to this 
treatment, with a clinical response observed in the patients participating in the trial.

7 STUDY DESIGN 
This is an open-label Phase Ib dose confirmation and proof of concept study in up to 24 
patients with end stage castrate resistant prostate cancer who are being considered for or 
undergoing palliative radiation therapy for pain and symptom management.  Patients will 
have a minimum of one (1) lesion which is amenable to radiation therapy. Palliative RT (20Gy 
over 5 fractions) will be delivered to selected lesion in combination with rectally administered 
idronoxil (NOX66).  
This study is intended to provide information regarding the safety of this treatment 
combination and justification for a larger Phase 2/3 study in the treatment of patients with 
combination of NOX66 and palliative radiation therapy. 
Clinical response to treatment will be assessed by radiological CT/MRI scans, where applicable 
objectively measures by RECISTv1.1, by pain response as evaluated by Brief Pain Inventory 
Short Form, ECOG scores and by monitoring PSA as surrogate marker with overall (observable 
and symptomatic) response based on data review by an independent Radiation Oncology 
Expert Committee (ROEC). Local response will be based on investigator review of data in 
conjunction with ROEC.  
PSA will be monitored as a surrogate marker of response and pain response will be evaluated 
using the Brief Pain Inventory Short Form throughout the study.  
Patients will be suitable for the study as they become eligible for, and will be given, palliative 
radiation therapy for management of their cancer. 
Three dose cohorts will be investigated in this study with dosing based on criteria outlined in 
section 10.2.7. The three doses of idronoxil investigated include: 
- 
400mg idronoxil provided as one NOX66 suppository per day 
- 
800mg idronoxil provided as one NOX66 suppository twice daily 
- 
1200mg idronoxil provided as one NOX66 suppository three times daily. 
Treatment will be for one cycle of combined radiation therapy and NOX66 with follow up 
assessments at Week 6, Week 12, Week 24 and every 3 months for the following 18 months.  
All patients will be followed up for disease progression and survival information either by 
retrospective review of medical records or by a physical visit or by telephone follow up call.

The drug can be administered at any time during the day, but the same time should be used 
each day. Twice daily doses should be administered at approximately 8 to 12hour intervals 
and for three times daily dosing, first dose to be administered in the morning and two doses 
administered should be administered at approximately 8-12 hours later. A missed dose should 
be taken as soon as it is noted as missed. Taking two suppositories at the same time is 
permitted in order to catch up a missed dose within a day. No more than three suppositories 
should be taken in a 24-hour period. 
 
9.3 RADIATION THERAPY 
External beam radiation therapy will be applied to a minimum of one or more selected lesions 
in 5 daily fractions, over five to eight days, at a dose of 20Gy.  
The number of lesions to be irradiated will be at the discretion of the investigator as clinically 
indicated. Lesions which directly receive radiotherapy will be categorized as “irradiated 
lesions” with all other lesions identified as “non-irradiated lesions”.  
Lesions will be assessed by the investigational site at screening and any symptomatic lesion/s 
for irradiation which can be assessed by RECIST 1.1 criteria will be noted as “measurable 
irradiated target lesions” and symptomatic lesions that cannot be measured will be noted as 
“non-measurable lesions”. Further detail is provided in Section 10.4.8. Lesions will be 
captured by CT or MRI scan at baseline with follow-up CT/MRI imaging at Week 6, Week 12 
and Week 24. Scan image data will be stored on central planning system software (such as 
MIM) for radiological comparisons and response to treatment will be reported. 
During screening period, baseline lesion/s will be selected for irradiation and the gross 
tumour volume (GTV), the clinical target volume (CTV) and organs at risk (OAR) will be defined 
by the radiation oncologist based ICRU 50 or ICRU 83 guidelines.  
Radiation therapy will be delivered to target labelled irradiation lesions according to the study 
radiation treatment plan developed. Details are provided in the NOX66-002A Radiation 
Therapy Planning, Delivery and QA Guidelines which must be used as the primary source for 
planning and delivering radiation therapy treatment within the trial. 
Tumour lesions either for irradiation or not which, at baseline, are identified as measurable 
will be noted as target lesions and will be assessed for response to treatment according to 
RECIST 1.1 criteria. Symptomatic tumour lesion which at baseline is identified for irradiation 
but not measurable will be noted a non-measurable target lesion/s. 
All radiological scans during the study will be reviewed by the independent Radiation 
Oncology Expert Committee for each patient to assess overall response to treatment.

9.4 TREATMENT DOSE MODIFICATIONS AND TREATMENT CYCLE DELAY 
9.4.1 NOX66 
Any patient who experiences toxicity > Grade 2 related to NOX66 will have the idronoxil 
treatment withheld for 1 day and then resume on the next lower dosage (1200 mg reduced 
to 800 mg; 800 mg reduced to 400 mg; 400 mg daily reduced to 400 mg every 2nd day) for the 
remainder of the treatment period.  
If toxicity > Grade 2 persists following reduction of dose, the idronoxil treatment will cease 
immediately for the remainder of the treatment period, although the patient may remain in 
the study.  
There will be no dose modification of NOX66 on the basis of body weight.  
9.4.2 Radiation Therapy 
There will be no dose modification of radiation therapy. Any deviation from the planned dose 
of radiation therapy will be reported by the investigator in the CRF.  
 
9.5 ACCOUNTABILITY FOR CLINICAL SUPPLIES 
The Principal Investigator or delegate/s will be responsible for the dispensing, inventory, and 
accountability of all clinical supplies, exercising accepted medical and pharmaceutical 
practices. An accurate and timely accountability record log of the disposition of all clinical 
supplies must be maintained. The supplies and inventory record must be made available for 
inspection by the Sponsor or the designated Sponsor’s representative upon request. All used 
medication packaging and unused medication will be collected and retained until completion 
or termination of the study. Once all drug accountability has been performed and monitored 
the Investigator or delegate/s will destroy NOX66 as per Site Pharmacy SOPs and/or return all 
remaining clinical supplies to the Sponsor who will destroy the study drug on the site’s behalf. 
Under no circumstances will the Principal Investigator allow NOX66 to be used other than as 
directed by this protocol. 
 
9.6 CONCOMITANT MEDICATIONS 
Patients are permitted a wide range of medications for general health, although this is to be 
confirmed with the Sponsor prior to enrolment into the Study. 
Patients are permitted certain medications specifically related to their metastatic disease, 
including use of androgen deprivation therapy (ADT) such as luteinizing hormone-releasing 
hormone (LHRH) agonists and antagonists. Other therapies are to be confirmed with the 
Sponsor medical monitor prior to enrolment in the Study.

Patients are not permitted any other experimental treatments. Supportive care measures and 
treatment for symptom control are permitted, including analgesics. Treatment of 
constipation or diarrhea is permitted however the investigator must determine the suitability 
of these patients to continue taking suppositories should these adverse events (as scored by 
NCI CTCAEv4.03) be reported. Patients will be medically monitored so that any adverse events 
will be identified promptly and treated appropriately.  
Details regarding the name, indication, route of administration, dose, and frequency of all 
medications taken within 14 days prior to study drug administration will be recorded in the 
eCRF at the Screening Visit and Day 1. Details regarding the name, indication, route of 
administration, dose, and frequency of all medications taken during the study will be recorded 
in the eCRF at each patient visit. “All medications” should include prescription, over-the-
counter (OTC) medications, dietary/nutritional supplements, and herbal products.

10.2.14  Cohort Allocation and Dose Escalation 
This study will enrol up to 24 patients across three dose levels of NOX66. Dose cohort 
assignment will be sequential and dose escalation decisions will be based on patients who 
experience adverse events directly related to NOX66 treatment and discontinued as 
described below and outlined in Figure 2. 
Dose escalation and decision rules are as follows: 
• Patients 1-4 (Dose Cohort 1) will be prescribed NOX66 400mg.  
 
• Patients 5-8 (Dose Cohort 2): Once fourth patient in Cohort 1 has completed 
treatment (Visit 7), the dose of NOX66 for next cohort, patients 5-8, will be as 
determined as follows, based on the number of discontinuations due to NOX66 
related adverse events: 
o If no patients discontinue treatment, NOX66 dose will be increased to 800mg 
o If one patient discontinues treatment, NOX66 dose will remain at 400mg 
o If more than one patient discontinues treatment, there will be no further 
recruitment to the study until scans from WEEK 6 are assessed for disease 
status 
  
• Patients 9-12 (Dose Cohort 3): Once the eighth patient in Cohort 2 has completed 
treatment (Visit 7), the dose of NOX66 for next cohort, patients 9-12, will be as 
determined as follows, based on the number of discontinuations due to NOX66 
related adverse events: 
o If no patients in Dose Cohort 2 discontinue treatment, NOX66 dose will be 
increased (from 400mg to 800mg or from 800mg to 1200mg) 
o If one patient in Dose Cohort 2 discontinues treatment, NOX66 dose will 
remain at the same dose (400mg or 800mg) 
o If more than one patient in Dose Cohort 2 discontinues treatment, dose will be 
reduced (from 800mg to 400mg) or, if dose has remained at 400mg, there will 
be no further recruitment to the study until scans at WEEK 6 are assessed for 
disease status.

Page 40 of 64 
• all medical conditions and disease states that require current or ongoing therapy, 
and  
• other medical conditions and disease states that, in the opinion of the Investigator, 
are relevant to the patient’s study participation 
 
10.4.2 Physical examination 
The physical Examination performed in this study will include  height, weight, blood pressure, 
pulse and body temperature and a physical (external) assessment of the patient. Blood 
pressure and pulse may be measured whilst the patient is sitting or lying but must be 
measured consistently for the patient throughout the study. Temperature should be 
measured in accordance with the centre’s standard practice. Any significant abnormalities 
noted during the physical examination at screening should be reported in the Medical History. 
Any significant changes noted on follow up physical examination should be reported as 
adverse events.  
10.4.3 ECOG Performance assessment 
A patient’s performance Status will be assessed using the Eastern Co-operative Oncology 
Group (ECOG) Performance Score (Appendix 1).   
10.4.4 Electrocardiography 
12-lead ECGs will be taken using a serviced and calibrated machine in triplicate, within 5 
minutes of each other (over 15 minutes), to calculate the mean QTc value to ensure the 
patients eligibility for study enrollment. ECGs should be taken after the patient has been 
resting supine for 5 minutes. 
ECG will be performed at three timepoints throughout the study – Screening, End of 
Treatment visit and end of study. Any abnormalities noted during the physical examination at 
screening should be reported in the Medical History. Any changes noted on follow up ECG on 
should be reported as adverse events. 
10.4.5 Brief Pain Inventory-Short Form 
Pain will be evaluated using the Brief Pain Inventory-Short Form instrument (Appendix 2). 
Total score is an average of the pain interference score (mean value for the nine BPI-SF items) 
and pain subscale score (mean value for the nine BPI-SF items 3,4,5 and 6).  
Questions on pain interference inquiring about extent of interference with activities by pain 
on scale of 0 (does not interfere) to 10 (completely interferes). 
Questions on pain inquire about extent of pain on scale of 0 (no pain) to 10 (pain as bad as 
you can imagine). 
Total score ranges from 0 to 10 with higher values indicating more pain. 
The BPI-SF questionnaire will be administered at six timepoints throughout the study- 
Screening (baseline), End of Treatment visit 7, at Week 6, 12, 18 and 24 post treatment.

Overall pain improvement response is defined as a decrease in pain score greater or equal to 
30% at 12 weeks relative from baseline without overall increase in opiate use and confirmed 
at least 2 weeks later per PCWG3 guideline41. 
 
10.4.6 Safety Blood Sampling 
Non-fasting samples for clinical laboratory analysis will be collected as listed below:  
• Complete blood count (CBC) including: white blood cells with differentials, red blood 
cells, haemoglobin, haematocrit, mean corpuscular volume (MCV), mean corpuscular 
haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), platelet 
• Serum chemistry panel including sodium, potassium, calcium, creatinine, total 
protein, albumin, bilirubin (total, direct), AST/SGOT, ALT/SGPT, alkaline phosphatase 
(ALP) 
• Urinalysis dipstick - Clarity, specific gravity, pH, protein, glucose, ketones, nitrite, 
leukocytes, and blood.  Urine microscopy will be performed if urinalysis values are out 
of range and the Investigator deems that the microscopy is clinically warranted 
Haematology, clinical chemistry and urinalysis will be performed by the site’s local 
accredited laboratories. 
10.4.7 Biomarker Sampling    
• PSA levels will be collected at baseline, and post treatment cycle at Visit 8 (Day 43), 
Visit 9 (Day 84) , Visit 10 (Day 168) and Visit 11 – Visit 16 (every 3 months after Visit 
10) to determine any response to treatment. PSA samples will be collected by 
standard practice and analysed at each site’s local laboratory. 
Idronoxil: Plasma samples will be collected at baseline and Visit 7 (Day 16+1) of 
treatment cycle and post treatment at Visit 8 (Day 43) to determine levels of any 
accumulation during and post treatment.   Instructions for idronoxil plasma collection 
will be provided by Sponsor and analysis will be undertaken by the Sponsor performed 
by a designated laboratory. 
10.4.8 Tumour Imaging 
Tumour imaging by CT/MRI will be performed in line with local practices using a planning 
software system.  
Baseline documentation of Target and Non-Target lesions 
‘Target’ lesions are assessed at the designated scanning time points and defined as lesions 
that are measurable and: 
Irradiated, such as soft tissue and lytic bony lesions, have defined margins for 
measurement and are irradiated at the discretion of the investigator. These lesions 
will be noted as ‘irradiated measurable target’. 
• Non-irradiated and these lesions will be noted as ‘non-irradiated measurable target’.  

NOXOPHARM LIMITED 
 
CONFIDENTIAL 
Protocol NOX66-002A 
Version 5.1, 11 July 2019 
 
Page 42 of 64 
For measurable lesions, the Longest Diameter (LD) of each lesion will be measured and a sum 
of the LD will be calculated and reported as the baseline sum LD. The sum LD will be used as 
reference by which to characterize the objective tumour response based on RECIST v1.1 
criteria (see below). 
Patients will undergo baseline CT or MRI body scan. A maximum of 5 lesions in total, with no 
more than 2 lesions per organ, will be identified as target lesions.  
 ‘Non-Target’ lesions include all other lesions and are recorded at baseline as either 
measurable or non-measurable. For non-measurable lesions, the presence or absence of each 
will be noted throughout follow-up scanning time points. For measurable lesions, size (mm) 
will be noted throughout follow-up scanning time points. 
These can include irradiated lesions such as sclerotic bone lesions, which do not have defined 
margins for measurements and are irradiated at the discretion of the investigator. These 
lesions will be assessed for local response based on patient reported outcome using the BPI-
SF (see section 10.4.5). 
Review of all CT/MRI scans per patient will be conducted by the independent Radiation 
Oncology Expert Committee as outlined in Section 10.4.9. 
 
RECIST evaluation of target lesions 
Assessment of irradiated measurable lesions will be conducted according to the RECIST1.1 
Criteria for response on the CT or MRI scan, as set out below.  
Complete Response (CR): 
Disappearance of all relevant target lesions 
Partial Response (PR): 
At least a 30% decrease in the sum of the LD of relevant target lesions, 
taking as reference the baseline sum LD 
Stable Disease (SD): 
Neither sufficient shrinkage to qualify for PR nor sufficient increase to 
qualify for PD, taking as reference the smallest sum LD since the 
treatment started 
Progressive Disease (PD): 
At least a 20% increase in the sum of the LD of relevant target lesions, 
taking as reference the smallest sum LD recorded since the treatment 
started or the appearance of one or more new lesions. 
 
Evaluation of non-target lesions 
Non-measurable Assessment: 
Complete Response (CR): 
Disappearance of all non-target lesions and normalization of tumour 
marker level

Page 43 of 64 
 Non-CR/Non-PD: 
Persistence of one or more non-target lesion(s) or/and maintenance of 
tumour marker level above the normal limits 
Progressive Disease (PD):  
Appearance of one or more new lesions and/or unequivocal  
progression of existing non-target lesions. 
Measurable Assessment: 
Response  
Percent change in lesion size based on sum LD (mm) taking as reference 
the baseline sum LD.  
 
10.4.8.1 Radiological assessment of tumours during long term follow up period 
(Visit 11-16)   
Radiological assessments will be at the discretion of the investigator.  The disease status 
assessment will be based on local radiology results. No central radiographic assessment will 
be undertaken during the long term follow up period.  
 
10.4.9 Radiation Oncology Expert Committee 
A Radiation Oncology Expert Committee (ROEC), comprising medical Oncologists, Radiation 
Oncologists and Radiologists independent of the study sponsor, will be formed to assess 
clinical progression of patients on the study. The ROEC will receive copies of all CT/MRI scans 
(including any with RECIST measures), PSA measures, ECOG and pain score measurements for 
review and provide an assessment of overall clinical evaluation of response per patient which 
will be documented according to sponsor guidelines. This assessment will be used to support 
the definition of endpoints for future studies. 
 
11 DATA COLLECTION AND MANAGEMENT 
11.1 METHODS 
It is the responsibility of the Principal Investigator to ensure that there will be primary source 
documentation for all patient data collected as part of the study, and the data will not be 
recorded onto the eCRFs without the availability of such primary documentation. For this 
study, there is no data which has been permitted for direct data entry without source 
documentation. The source data may include such documents as clinical notes, laboratory 
result sheets, pathology reports, radiology results, etc., and will be retained in each patient’s 
medical record or research chart. CRFs will be provided by the Sponsor. 
The Principal Investigator or delegate/s will be responsible for the timeliness, completeness, 
and accuracy of the information entered on the CRF. The Principal Investigator will provide 

NOXOPHARM LIMITED 
 
CONFIDENTIAL 
Protocol NOX66-002A 
Version 5.1, 11 July 2019 
 
Page 44 of 64 
access to the Medical Monitor or designated Sponsor representative(s) for the periodic 
review of all study records, source documents among other records for review and inspection 
to assure accuracy and completeness of the CRFs. All CRFs will be 100% source verified against 
corresponding source documentation (e.g., office and clinical laboratory records) for each 
patient. 
The Sponsor and designated Sponsor representative(s) will maintain frequent contact with 
each site to assure the study is conducted according to the protocol and that all data collected 
are accurate and complete. Any deficiencies identified during the study will be communicated 
to the site for prompt correction. 
11.1.1 Case report form 
All information relative to the study will be recorded into a 21 CFR part 11 FDA compliant 
electronic Case Report Form (CRF).  Data corrections will be entered by the authorised site 
personnel. 
11.1.2 Return and storage of forms 
The Investigator will retain the copies of the CRF and all other study related documents for 
15 years from completion of the study. 
 
11.2 DATA MANAGEMENT 
11.2.1 Data Coding 
Medications will be coded from the WHO Drug Dictionary and medical history and adverse 
events will be coded using the MedDRA terminology for System Organ Class (SOC) and 
Preferred Term (PT). 
11.2.2 Data validation 
A Data Management Plan which fulfils the requirements for ICH GCP will be developed to 
describe all manual and electronic validation checks of the data prior to analysis. Data queries 
requiring clarification will be documented on the EDC eCRF for the investigational site to 
resolve. Only authorised personnel will make corrections to the clinical database, and all 
corrections will be documented in an electronic audit trail.  
12 STATISTICAL SECTION 
12.1 SAMPLE SIZE 
The study is intended as a Proof of Concept and dose confirmation study, providing 
justification for and guidance on the design of further studies. 
The primary objective of this study is to observe safety and tolerability of idronoxil (NOX66) 
in combination with radiation therapy (at palliative doses). In conjunction with observations 

NOXOPHARM LIMITED 
 
CONFIDENTIAL 
Protocol NOX66-002A 
Version 5.1, 11 July 2019 
 
Page 45 of 64 
from the other phase 1 trials in the NOX66 development program, 24 patients are considered 
adequate to inform on toxicity and safety in order to progress to phase 2/3.   
Palliative Radiation therapy alone is unlikely to provide more than a minor and temporary 
reduction (<30%) in tumour size. Any responses greater than this will be considered to be 
related to NOX66 use. Any signals of efficacy will be described in the Clinical Study Report and 
used to support the Phase 2/3 development program. 
12.2 STATISTICAL METHODOLOGY 
This section describes the planned statistical analyses in general terms. A complete 
description of the statistical analysis will be specified in a statistical Analysis Plan (SAP) 
finalised prior to completion of the study. 
General: Data will be summarized by using counts and percents for discrete parameters, and 
by descriptive statistics (e.g. number of observations, mean, standard deviation, median, 
minimum and maximum) for continuous parameters. Subject disposition and baseline 
characteristics will be presented for all treated patients. Data will be analysed as collected. 
No imputation of values for missing data will be performed. Standard clinical monitoring and 
data management practices will be used to ensure the integrity of the data. 
Populations for analysis: There will be two study populations defined for this study. The 
safety population will consist of all patients who received at least one dose of NOX66. This 
population will be used in all safety summaries. The efficacy population will consist of all 
patients who complete radiation therapy with at least 7 days of NOX66 dosing. 
Baseline Comparisons and Patient Disposition: Demographic and baseline disease 
characteristic data summarisation will be performed in order to descriptively document any 
safety and efficacy findings. Data to be tabulated will include demographic features such as 
age and race, as well as medical history. The number and percentage of patients who 
complete the study or who withdraw for any reason will be presented. 
Efficacy Analysis: Results from (i) RECIST 1.1 response assessment for target lesions and non-
target lesions, (ii) ECOG Performance Score and (iii) Pain scores. Changes form baseline in 
levels of serum PSA levels will be listed. 
Overall and progression-free survival, PSA and pain scores collected during the extended 
follow-up period will be summarized in the same manner as for the immediate post-
treatment follow-up period. 
Safety Analysis: The safety will be assessed through the analysis of the reported incidence of 
treatment emergent AEs, including SAEs, dose-limiting toxicities, AEs leading to withdrawal, 
events of at least CTCAE Version 4.03 Grade 3 in severity, and AEs related to study treatment. 
Treatment emergent AEs are those with an onset on or after the initiation of therapy. Other 
safety endpoints include laboratory results, physical examinations, vital signs, and changes in 
ECOG status. A copy of CTCAE Version 4.03 scoring system may be downloaded from:

http://evs.nci.nih.gov/ftp1/CTCAE/CTCAE_4.03_2010-06-14_QuickReference_8.5x11.pdf. 
The adverse events will be summarized by MedDRA coding terms, System Organ Class (SOC), 
and preferred term for all treated patients and by dose cohort. The AEs will also be tabulated 
by maximum severity and maximum relationship to study drug where applicable. The number 
and percent of patients experiencing dose-limiting toxicities will be summarized by dose 
cohort, by DLT, and system organ class for all treated patients. Other safety endpoints, which 
include change from baseline in laboratory results and vital signs, and shifts in physical 
examinations, will be summarized throughout the study by visit for each dose level for all 
treated patients. 
Concomitant medications:  are to be listed for all patients. 
 
12.3 PROCEDURES FOR HANDLING MISSING, UNUSED AND SPURIOUS DATA 
No imputation of values for missing data will be performed. Standard clinical monitoring and 
data management practices will be used to ensure the integrity of the data 
Interim analysis 
Interim analyses will be conducted after last patient in dose Cohort 3 has completed 6-week 
follow up (Visit 8) and will be used to determine the progress of the study and dose decision 
for expansion Cohort 4. Further analysis will be conducted after each cohort has completed 
12 and 24 weeks follow up (Visit 8 and 10).

13 MONITORING 
13.1 MONITORING OF CASE REPORT FORMS 
The study will be monitored by a CRO on behalf of the Sponsor. Monitoring will be conducted 
per ICH GCP guidelines and Sponsor SOPs. The Monitor will visit the Investigator at regular 
intervals to review the progress and conduct of the study. The CRFs will be checked for 
completeness and accuracy against the patient records, charts, laboratory reports, and scans. 
Anonymity of the patient will be maintained at all times. 
13.2 SAFETY DATA MONITORING 
The Study Steering Committee (SSC) will review and evaluate all toxicities causally associated 
with NOX66 treatment and or the radiation therapy combination therapy. The SSC will consist 
of:  
• Principal Investigator from each clinical site, or medical designee 
• Sponsor’s Medical Monitor 
• CRO Medical Representative (if applicable) 
• Director of Clinical Development, Noxopharm Ltd 
Review of any adverse events of Grade 2 toxicity and above, considered by the Principal 
Investigator to be related to idronoxil (NOX66), will be reported to the SSC immediately and 
decision on the continuation of the patient individually, and the study in general, will be 
provided.  
The Study Steering Committee will review the Safety Data and determine dose cohort 
escalation following completion of treatment cycle (Visit 7) of final patient in a cohort.  
The SSC will determine the dose for cohort expansion based on the review of accumulated 
safety data, on treatment response and disease evaluation following WEEK 6 assessments of 
all patients and determine continuation of the study.  
 
13.3 AUDITING 
Regulatory authorities, the HREC/EC or the Sponsor may request access to patient clinical 
notes and other relevant study documentation for an on-site audit or inspection at any time 
during or after study completion. The Investigator is obliged to facilitate this process by 
allowing full access.

14 ADVERSE EVENTS REPORTING 
Adverse events (AE) or serious adverse events (SAE) reported by the patient or observed by 
the Investigator will be listed individually on an adverse event form in the CRF. The signs and 
symptoms, time of onset, duration, treatment (if any), and follow-up procedures (if any) will 
be reported, and the criteria for assessing causality to study drug and outcome categories 
should be defined. 
Pre-existing conditions or illnesses which are expected to exacerbate or worsen are not 
considered adverse events and will be accounted for in the patient’s medical history. 
All adverse events are to be followed up for 30 days following the end of study or until 
resolution (whichever is sooner).  
In order to classify AEs and diseases, preferred terms will be assigned by the Sponsor to the 
original terms entered on the eCRF using the Medical Dictionary for Regulatory Activities 
(MedDRA). 
14.1 DEFINITIONS 
14.1.1 AE 
AE is any un-anticipated or unintended medical occurrence or worsening of a sign or symptom 
(including an abnormal laboratory finding) or disease in a study participant, which does not 
necessarily have a causal relationship with the study condition, procedures or study agent(s) 
that occurs after the informed consent is obtained. 
14.1.2 SAE 
An SAE is defined as any untoward medical occurrence that results in death, is immediately 
life-threatening, requires at least a 24-hour in-patient hospitalization or prolongation of 
existing hospitalization, results in persistent or significant disability/incapacity, or is a 
congenital anomaly/birth defect. 
The definition of SAE also includes any important medical event. Medical and scientific 
judgment should be exercised in deciding whether expedited reporting is appropriate in other 
situations, such as important medical events that may not be immediately life-threatening or 
result in death or hospitalization but may jeopardize the patient or may require intervention 
to prevent one of the other outcomes listed in the previous definition. These should also 
usually be considered serious. Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm; blood dyscrasias or convulsions that 
do not result in hospitalization; or development of drug dependency or drug abuse. 
Progression of malignancy (including fatal outcomes), if documented by the use of an 
appropriate method (for example, as per RECIST 1.1 criteria for solid tumours), should not be 
reported as an SAE and must be approved by the Sponsor.

Version 5.1, 11 July 2019 
 
Page 49 of 64 
Treatment within or admission to the following facilities does not meet the criteria of “in-
patient hospitalization” (although if any other SAE criteria are met, the event must still be 
treated as an SAE and immediately reported): 
• Emergency Department or Emergency Room  
• Outpatient or same-day surgery units 
• Observation or short-stay unit  
• Rehabilitation facility  
• Hospice or skilled nursing facility  
• Nursing homes, custodial care or respite care facility  
Hospitalization during the trial for a pre-planned surgical or medical procedure (one which 
was planned prior to entry in the trial), does not require reporting as a SAE to the Medical 
Monitor and Sponsor. 
The definition of “related” is that there is a reasonable possibility that the drug caused any of 
the adverse events described in Table 2. 
14.1.3 Guidelines for determining causality and severity 
The criteria used for determining the relationship between the study drug/s and the Adverse 
Event are shown in Tables 2 and 3: 
Table 2 Criteria for determining relationship between AE and idronoxil (NOX66) 
Unlikely/unrelated: 
An AE with a temporal relationship to drug administration, which makes a causal 
relationship improbable, and in which other drugs, chemicals or underlying 
disease provide plausible explanations.  
Possible 
An AE with a reasonable time sequence to administration of the drug, but which 
could also be explained by concurrent disease or other drugs or chemicals. 
Information on drug withdrawal may be lacking or unclear. 
Likely 
An AE with a reasonable time sequence to administration of the drug, unlikely to 
be attributed to concurrent disease or other drugs or chemicals, and which 
follows a clinically reasonable response on withdrawal (rechallenge). Rechallenge 
information is not required to fulfil this definition 
Certain 
An AE occurring in a plausible time relationship to drug administration and cannot 
be explained by concurrent disease or other drugs or chemicals. The response to 
withdrawal of the drugs should be clinically plausible. The event must be 
definitive pharmacologically or phenomenologically using a satisfactory 
rechallenge procedure if necessary and feasible

14.2 RESPONSIBILITIES FOR REPORTING 
Investigators and the Sponsor are required by regulatory agencies worldwide to report 
adverse events which involve patients being administered a pharmaceutical product.  
All serious adverse events (SAE) occurring from the signing of informed consent until 30 
calendar days after last study visit whether related to drug or not, must be reported to the 
Medical Monitor and appropriate Sponsor contact person within 24 hours of first knowledge 
of the experience using the appropriate study SAE Report Form. SAEs are to be followed until 
resolution or stabilisation (with autopsy report if applicable). 
Although pregnancy is not a formal SAE, if the study participant or the partner of a study 
participant becomes pregnant while the study participant is on study, the pregnancy is to be 
reported on the pregnancy report form via the SAE process. 
Deaths and other SAEs occurring > 30 calendar days after last study visit that are deemed 
‘possibly’ or ‘probably’ related to the study treatment must be reported as SAEs on the SAE 
Report Form within 1 day of first knowledge of the event by the treating physician or research 
personnel (with an autopsy report if available). 
Deaths occurring > 30 calendar days after last study visit and not attributed to study 
treatment (e.g., disease progression) need not be reported as SAEs, but simply captured on 
the appropriate CRF. 
The investigative sites will send the SAE report to the Sponsor’s Medical Monitor via fax or e-
mail and to the Sponsor’s pharmacovigilance manager using the contact information below.

Transmission of the SAE Report Form should be confirmed by the site personnel submitting 
the report. The first report must contain as minimum the study ID, patient number, a description 
of the event, the name of the investigational product, estimate of causality and the name of the 
person reporting the event. 
14.2.1 SAE and Unresolved AE Follow-Up 
Follow-up information for SAEs and information on non-serious AEs that become serious 
should also be reported to the Medical Monitor as soon as possible using the SAE Report 
Form.  
The patient should be followed until it is determined that the event resolved, stabilized, or in 
the opinion of the Investigator the event is not going to improve due to underlying disease, 
or the patient is lost to follow-up. 
Investigators must report SAEs and follow-up information to their responsible HREC according 
to the policies of the responsible HREC. 
The detailed SAE reporting process will be provided to the sites in the SAE reporting guidelines 
contained in the study reference manual. 
14.2.2 Investigator Reporting of AEs/SAEs/Deaths after Study Discontinuation 
Thirty days after completing protocol-specific treatment or study discontinuation, treatment 
related AEs, SAEs, or deaths determined by the Investigator as treatment related are to be 
reported directly to the Sponsor. 
At the last scheduled study visit, the Investigator should instruct the patient to report to the 
Investigator any subsequent SAEs that the patient or the patient’s personal physician believes 
could be related to prior study treatment. 
SAEs after study discontinuation considered related to study treatment are to be sent to the 
Sponsor.

15 CONDUCT OF STUDY 
15.1 HUMAN RESEARCH 
The Protocol and all other relevant study documents (informed consent, advertising etc) will 
be submitted to the site Human Ethics Review Committee (HREC) and to regulatory 
authorities in the countries where the study will be conducted.  
Written confirmation of approval (noting version/ date of all approved documents) must be 
received the Investigator before the study commences and approval of all documents 
pertaining to this study will be kept in the study Master file. 
The HREC will have at all times the right to review all source documentation. 
 
15.2 GOOD CLINICAL PRACTICE 
The study will be conducted in accordance with the principles of good clinical practice (GCP) 
using the guidelines established in 1996 by the International Council on Harmonisation (ICH), 
annotated in July 2000 by the TGA.  
Compliance with these guidelines ensures compliance with the currently approved version of 
the Declaration of Helsinki (October 2000) with notes of Clarification in 2002 (Washington) 
and 2004 (Tokyo) and any local legal and regulatory requirements. 
 
15.3 ADHERENCE TO PROTOCOL 
No changes or deviations in the conduct of this protocol will be permitted, with the exception 
of emergency situations. The Investigator should contact the Sponsor by telephone as soon

The Principal Investigator, or a person designated by the investigator, is responsible to explain 
the nature of the study and the risks and benefits of taking part to the patient in order to 
obtain the patent's written consent. It should be stressed that participation is voluntary. The 
patient can refuse to participate and is free to withdraw from the study at any time, without 
affecting their future medical management.  
Prior to undertaking any study specific activity, the Investigator should explain the nature of 
the study to the patient, including providing a written information sheet which should be read 
and retained by the patient. All patients must give fully informed consent, which must be 
obtained in writing by a personally dated signature and witnessed. The signed consent form 
should be available to be viewed by the Clinical Study Monitor and a copy of all consent 
documents provided to the patient. 
Patients must be informed that representatives of the Sponsor, HREC and regulatory 
authorities may inspect their medical records in order to verify the accuracy and authenticity 
of study documentation including information entered in the eCRF. Patients must be 
informed as to the nature of the privacy guidelines in place to protect their anonymity. 
Any amendments to the Informed Consent Form will need to be approved by the Sponsor and 
the HREC. 
17 DISCLOSURE OF DATA 
17.1 CONFIDENTIAL INFORMATION 
Patient medical information obtained during the study is confidential and disclosure to third 
parties other than those noted below is prohibited. All patients will be assigned a study 
identification number.
