Dear Shareholders, 
 
It is my pleasure to write to you as the CEO and Director of Helix BioPharma. As you all are aware, we faced some unprecedented 
challenges in 2022 with the passing of our interim CEO Dr. Slawomir Majewski and the resignation of two of the directors due to 
personal circumstances. But we have recovered from these challenges with a positivity attitude and determination to take the 
Company forward to the benefit of patients suffering from cancer across the world.  
 
We continue to maintain our focus on developing unique therapies in the field of immuno-oncology for the treatment of cancers. 
The team is very excited with the progress we have been making and we look forward to making strides in the coming years. As 
in the previous years, our clinical program remains our highest priority to ensure we deliver on a substantial data package that 
would ultimately benefit patients and stakeholders alike. 
 
We continue to partner with experienced advisors, institutions and experts in the field to enhance the value of our platform asset 
and have made the following progress during this challenging environment.  
 
Clinical Development 
 
LDOS47 in lung cancer 
 
Ø 
The Phase I study combination therapy in lung cancer (LDOS001) was completed and the final clinical trial report issued 
in December 2021. A manuscript was accepted for publication in Journal of Thoracic Oncology Clinical and Research 
Reports on September 2nd, 2022. A pre-print can be found here: https://www.jtocrr.org/article/S2666-3643(22)00132-
1/fulltext#relatedArticles. 
Ø 
The Phase II study of combination therapy in lung cancer (LDOS003) was halted in the dose escalation portion of the 
study in 2020 at the height of pandemic lockdown and the final abbreviated clinical trial report has  been further delayed 
amidst war in Ukraine where all subjects were recruited. A final effort is being made in an attempt to retrieve any data 
that is salvageable and conclude the study. 
Ø 
Another important aspect of the development of the LDOS47 platform is the combination with chemo- and/or immuno-
therapy, that may boost the utility of the platform. The Company has engaged several key opinion leaders to evaluate 
the feasibility of such combinations and aims to develop a develop a roadmap by the end of 2022. 
 
LDOS47 in pancreatic cancer 
 
Ø 
The Company's Phase Ib/II combination trial in pancreatic cancer (LDSOS006) continues to recruit patients. We recently 
applied to the U.S. Food and Drug Administration for a revision to the clinical study protocol to extend the number of 
treatment cycles for those patients where the benefits outweigh the risks. We remain committed to this study. The first 
dosing cohort was successfully completed and now the second dosing cohort is also nearing completion. 
 
Corporate Development  
 
Ø 
In Q3 and Q4, we raised approx. $6,213,204 through two private placements and the Early Warrant Exercise Incentive 
Program.  
 
Ø 
The board of directors was reconstituted in April 2022, following the death of Slawomir Majewski, Interim CEO and the 
resignation of other two directors, Dr. Krzysztof Saczek and Mr. Adam Uszpolewicz. Three new independent directors 
– Mr. Jacek Antas, Jerzy Leszczyński and Mr. Christopher Maciejewski were appointed to the board of directors, while 
I was  appointed by the board to serve as the Chief Executive Officer. 
 
Ø 
Mr. Hatem Kawar succeeded Mr. Frank Michalargias as the Chief Financial Officer effective May 18, 2022.  
 
Our progress under these challenging times would not have been possible without the strong support from our employees and 
stakeholders, and I’m truly thankful for their dedication and commitment. Advancing our DOS47 platform and establishing a third-
party partnership while raising sufficient capital to continue strengthening our operations and portfolio remains our highest priority. 
We have good momentum going into the financial year 2023. We expect continued growth ahead and we are well positioned to 
build shareholder value over the long term. We appreciate your confidence and continued support. 
 
 
Sincerely, 
Artur Gabor  
CEO and Director

OVERVIEW 
 
Helix is a clinical-stage biopharmaceutical company developing unique therapies in the field of immuno-oncology for the prevention 
and treatment of cancer based on its proprietary technological platform DOS47.  
The Company is pioneering the development of a platform technology targeting the tumour microenvironment. Helix's technology 
is designed to reduce tumour acidity, an escape mechanism that cancer cells utilize to evade the anti-tumour immune response. 
Tumour acidity has been shown to correlate with resistance to anti-cancer treatment and poor prognosis for cancer patients.  
To date, the Company’s proprietary technology platform, DOS47, has yielded two new drug product candidates, L-DOS47 and V-
DOS47. 
 
The Company completed extensive preclinical testing and manufacturing development of L-DOS47, following which the Company 
obtained regulatory approvals to conduct a Phase I/II NSCLC monotherapy clinical study in Poland, a Phase I NSCLC combination 
study with pemetrexed and carboplatin in the United States, and a Phase II NSCLC combination study with vinorelbine and cisplatin 
in Ukraine and Poland. In August 2019, the Company also received approval to conduct a Phase Ib/II combination study utilizing L-
DOS47 with doxorubicin in patients with previously treated advanced pancreatic cancer in the United States. 

5 
 
The Company’s V-DOS47 drug candidate uses the proprietary DOS47 technology conjugated to anti-VEGFR2 antibody targeting 
a wide range of cancers. In 2016, V-DOS47 was licensed to Helix Immuno-Oncology S.A., the Company’s then wholly owned Polish 
subsidiary, (“HIO”), for pre-clinical and clinical development activity. HIO entered into a grant funding agreement with the Polish 
National Centre for Research and Development (“PNCRD”) to fund the V-DOS47 research project. On January 30, 2020, HIO 
conveyed to the PNCRD that it wished to terminate the grant funding program for V-DOS47. As part of the debt cancellation 
agreements announced by the Company on June 26, 2020, the Company and HIO terminated the V-DOS47 license agreement.   
The Company cancelled intercompany debt in the total aggregate amount of approximately $2,700,000 owed to the Company by 
HIO.  As part of the debt cancellation, both the V-DOS47 and Biphasix™ agreements between the Company and HIO were 
terminated with immediate effect and transferred from HIO back to the Company without any formality. The Company has not yet 
assessed what next steps, if any, to take with the V-DOS47 antibody. 
 
In December 2019, the Company announced the start of enrollment and screening for its Phase lb/ll clinical development program 
for previously treated patients with advanced pancreatic cancer. The study center is located in Scottsdale, Arizona at the Scottsdale 
Hospital (dba “HonorHealth”). The Company originally forecasted patient enrollment in the Phase Ib portion of the study to be 
completed by the end of the 2020 calendar year, pending safety outcomes and the impact of the COVID-19 pandemic. As a result 
of the COVID-19 pandemic, the Company has not met the previously forecasted patient enrollment timeline for this clinical study. 
The Company added two new clinical sites in other U.S. jurisdictions during the first quarter of 2021 in order to facilitate patient 
enrollment. Please see “Our results of operations may be negatively impacted by the COVID-19 outbreak” under the heading “Risk 
Factors”. 
In 2017, the Company entered into a scientific research collaboration agreement with the Moffitt Cancer Center (“Moffitt”) in 
Tampa, Florida, to perform basic research studies to further investigate the pharmacodynamics of L-DOS47 and to determine the 
potential benefits of combining L-DOS47 with immune checkpoint inhibitors. The Company is assessing the possibility of 
expanding the scope beyond its research collaboration program with Moffitt.  The Company believes the ability of L-DOS47 to 
modulate tumour acidity may be key to enable immunotherapy treatment for selected cancers.  
 
A new research collaboration project initiated with the University Hospital of Tuebingen builds on data already obtained from 
imaging techniques performed by Moffitt that demonstrated the ability of L-DOS47 to affect tumour acidity. Extending the scope 
to further cancer models, and translation of the imaging technique into the clinic may help stratify patients for L-DOS47 and 
potentially identify patients who may be resistant to certain therapies due to tumour acidity.  
 
On June 26, 2020, the Company announced that it had approved, in its capacity as a shareholder of HIO, a direct investment in 
HIO by an investor which resulted in the Company’s ownership in HIO being reduced to approximately 42.51% on July 8, 2020. 
The direct investment in HIO permitted HIO to apply for a new government grant for the development of the multiple myeloma 
CAR-T program in Poland. On September 3, 2020, HIO closed another direct private placement with an arm’s length party, CAIAC 
Fund Management AG (“CAIAC”), as designated trustee of an alternative investment fund to be established, resulting in a further 
dilution of the Company’s holding in HIO from 42.51% as at July 31, 2020 down to 29.89%. As a result of the financing, the 
Company’s ownership in HIO was diluted down to 29.89% and consequently, the Company determined that it had lost control of 
HIO. During the year ended July 31, 2021, the Company received gross cash consideration of PLN 6,700,000 (CAD$2,308,000) 
for the balance of its shares in HIO ($2,020,000 net of costs of disposition), resulting in the full disposition of its interest in the 
associate. As of the date of this MD&A, the Company does not hold any equity in HIO. See Loss of control and deconsolidation 
of subsidiary – discontinued operations below. 
 
The Company has an extensive patent portfolio that includes company owned and licensed patents and pending applications, 
including, but not limited to, the use of DOS47 as immunoconjugate for cancer treatment. The Company also has licenses with 
the National Research Council of Canada (“NRC”) that cover the use of antibodies for L-DOS47, other DOS47 candidates and 
cellular therapy products. Issued patents have coverage in all major pharmaceutical markets including North America, Europe, 
and Asia.  
 
In August 2021, the Company retained the services of Lumanity Healthcare (Lumanity”), a highly experienced oncology 
consultancy group, to assess the Company’s drug product candidate with a focus on identifying value propositions and positioning 
strategies that would enable clinical adoption of L-DOS47, including broad clinical development key opinion leader input on the 
positioning of possible combination therapies and the prioritization of current and/or any additional clinical indications. 
 
Interviews conducted by Lumanity with key opinion leaders since its engagement with the Company helped validate the utility of 
certain of the clinical work completed by Helix to date and has assisted the Company to identify additional opportunities to further 
strengthen and de-risk the Company's clinical drug candidate program, including optimal selection of patients for trials 
(stratification) based on objective biomarkers, among other criteria. The Company anticipates that these activities may assist to 
initiate dialogue with potential market participants in cancer treatment, and that the additional preclinical data obtained could 
further enhance the Company's clinical program design.

RESEARCH AND DEVELOPMENT ACTIVITIES 
 
Background 
 
The pH system, with values ranging from 0 – 14, is used to measure acidity (pH < 7) and alkalinity (pH > 7). In general, the human 
body exists at a near-neutral pH - neither acidic nor alkaline (basic). In order for cells to function properly, they need the pH both 
inside and outside the cell to be neutral. There are some examples, however, where this rule is not followed. For example, the inside 
of the stomach is maintained at an acidic pH, as this helps to digest food. The cells lining the stomach have adapted to live in this 
acidic environment. 
 
Tumours also exist in an acidic environment. Normal tissues include an extensive network of blood vessels, which deliver oxygen 
and nutrients to cells and remove waste products. However, tumours contain an abnormal network of blood vessels. Because of 
this, tumours can become  hypoxic (receiving less oxygen than normal tissues) and need to use a non-oxygen requiring form of 
metabolism to provide energy for their survival and growth. One side-effect of this type of metabolism is that it generates an excess 
of hydrogen ions (H+) inside the cell, and hydrogen ions directly affect pH: the more hydrogen ions there are, the more acidic the 
inside of the cell becomes. Since a neutral pH inside the cell is essential for a cell to survive, tumour cells pump the excess hydrogen 
ions out of the cell. Due to the abnormal network of blood vessels, the excess hydrogen ions are not efficiently removed from the 
tumour microenvironment. Thus, the tumour microenvironment becomes acidic. 
 
The acidic microenvironment helps promote tumour survival and metastasis in a number of ways. The genes expressed by the 
tumour are affected by the acidic microenvironment, which allows tumour cells to adapt. One of these acid-induced changes is to 
increase production and release of proteases by tumour cells. The proteases destroy the protein matrix that surrounds the tumour 
cells, which makes it easier for the tumour cells to invade local tissues – a first step to metastasis. In addition, the acidic tumour 
microenvironment has been shown to impair the activity of immune cells in the tumour, which allows the tumour cells to avoid 
destruction by the immune system. 
 
The acidic tumour microenvironment also reduces the efficacy of common cancer treatments. Some chemotherapy drugs, such as 
doxorubicin, are weakly basic. The ability of these drugs to enter tumour cells, where they perform their function, is greatly reduced 
at acidic pH compared to neutral pH. Radiation therapy is also less effective at an acidic pH than at a neutral pH. 
 
It is clear that the acidic tumour microenvironment has a profound effect both on tumour biology and current therapies, and that 
neutralizing the pH of the tumour microenvironment may have a dramatic impact. One way to reverse extracellular tumour acidity 
is to inhibit the proteins that pump hydrogen ions out of tumour cells. One advantage of inhibiting these proteins is that not only is 
acidity of the extracellular tumour microenvironment reduced, but acidity inside the tumour cells increases, which has a negative 
effect on tumour cell viability. However, targeting these pumps is not easily achieved as many of them exist in multiple forms and 
some are critical for the function of normal cells. In addition, since there are several different pumps that regulate pH, inhibition of 
just one is generally insufficient to combat tumour acidity. 
 
A more general and theoretically more effective method to neutralize tumour extracellular pH is to use buffers. A variety of orally 
administered buffers have been effective in reducing tumour growth and/or metastases in preclinical animal studies. In addition, 
buffer therapies have been shown to enhance the activities of chemotherapy and immunotherapy. Although oral sodium bicarbonate 
buffer therapy was tested clinically, these trials failed due to poor compliance and moderate adverse effect. However, improved 
survival was seen in pancreatic cancer patients undergoing chemotherapy and “alkalization therapy” (produced by changes in diet 
and consumption of bicarbonate). 
 
Similarly, an alkaline diet likely improved responses to epithelial growth factor receptor – tyrosine kinase inhibitor (EGFR-TKI) 
therapy in non-small cell lung cancer (NSCLC) patients. Thus, a change in delivery method may allow for successful buffer therapy. 
Consistent with this hypothesis, administration of iv sodium bicarbonate nanoparticles improved doxorubicin efficacy in a preclinical 
breast cancer model. In addition, a clinical study was performed in which sodium bicarbonate was administered by local infusion 
into the tumour. In this study, hepatocellular carcinoma patients were treated with trans-arterial chemoembolization (TACE) with or 
without local bicarbonate. Patients receiving bicarbonate showed a 6-fold lower viable tumour residue, and a randomized controlled 
study showed that patients treated with bicarbonate had a higher objective response rate and cumulative overall survival in 
comparison to the patients treated with TACE alone. 
 
Alkalization using urease - DOS47 platform technology 
 
Although buffer therapies have the potential to neutralize the acidic tumour microenvironment, local administration of buffers is 
generally not feasible. In order to deliver alkalization therapy to tumours, the Company has developed DOS47, a proprietary 
technology platform. DOS47 compounds are conjugates of two components: the plant-based urease enzyme and an antibody that 
binds to a tumour-specific antigen. The antibody component targets the conjugate to tumours and the urease enzyme converts 
endogenous urea into metabolites that include ammonia and hydroxyl ions, thus raising the pH of the tumour microenvironment.

L-DOS47 
 
L-DOS47 includes an antibody that targets carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) 
Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) is a cell surface protein found to be upregulated in several 
types of cancer, including NSCLC and pancreatic cancer. In lung adenocarcinoma, CEACAM6 expression has been significantly 
associated with adverse clinical outcomes. Similarly, the median survival time of pancreatic adenocarcinoma patients with 
CEACAM6-positive tumours was significantly shorter than that of patients with CEACAM6-negative disease. 
L-DOS47 is composed of the Jack Bean urease enzyme conjugated to approximately ten (10) copies of a camelid single-chain 
anti-CEACAM6 antibody. The specificity of L-DOS47 for CEACAM6 was confirmed in in vitro binding studies where binding was 
only observed to cells that express CEACAM6. Immunohistochemistry studies showed binding of L-DOS47 to lung cancer and 
some pancreatic cancer tissues, but not to normal tissues. The ability of L-DOS47 to specifically target tumours was confirmed 
using a fluorescently labelled version of L-DOS47. These experiments were performed in a mouse model of lung cancer, and 
showed that for 12-72 hours after injection, LDOS47 was localized at the tumour. 
L-DOS47 has been shown to control tumour growth, reduce metastases, and enhance the effect of chemotherapy in animal 
models 
L-DOS47 was tested in two mouse models: one with lung cancer and one with pancreatic cancer. In both cases, administration of 
L-DOS47 reduced tumour growth compared to treatment with a control reagent. In addition, when lung cancer cells and L-DOS47 
were premixed and injected into mice, the presence of L-DOS47 reduced the ability of the tumour cells to colonize the lungs. The 
ability of L-DOS47 to improve chemotherapy efficacy was observed both in in vitro and in vivo preclinical experiments. In vitro 
experiments showed that at an acidic pH, L-DOS47 was able to dramatically increase the cytotoxicity of the weakly basic 
chemotherapeutic drug doxorubicin. In addition, a preliminary preclinical study showed that pre-treatment with L-DOS47 24 hours 
before doxorubicin delayed tumour growth in mice bearing a CEACAM6-positive pancreatic tumour. 
 
L-DOS47 has been shown to raise the pH of the tumour microenvironment and restore immune-cell activity 
Numerous experiments have been performed by the Company that monitored the production of ammonia and increase in pH 
when L-DOS47 was combined with urea in vitro. The ability of LDOS47 to raise the pH of the tumour microenvironment in vivo 
has been observed in both lung and pancreatic cancer models using multiple imaging methods including Phosphorus-31 Magnetic 
Resonance Spectroscopy (PMRS) and Chemical Exchange Saturation Transfer Magnetic Resonance Imaging (CEST MRI) (see 
images below). The Company has performed in vitro experiments with human CD8+ T cells and has observed that culture at acidic 
pH increased the expression of the programmed cell death protein 1 (PD-1) on the T cells, and that the T cells in acidic conditions 
reduced their production of the proinflammatory cytokine interferon-gamma (IFN-γ).  LDOS47 successfully restored the activity of 
these cells, as observed by reduced expression of PD1 and increased production of IFN-γ and another proinflammatory cytokine, 
interleukin-2 (IL-2).  In preliminary preclinical experiments, treatment with L-DOS47 enhanced the ability of an anti-PD1 antibody 
to control growth of pancreatic tumours in mice.

0.38 units. L-DOS47 was administered iv. Iopamidol was administered SC, next to the tumour. 
 
In summary, these preclinical experiments demonstrate that L-DOS47 successfully targets CEACAM6-expressing tumours, 
controls tumour growth, increases the pH of the tumour microenvironment, and  improves the efficacy of chemotherapy and 
immunotherapies. L-DOS47 is currently being tested in a clinical trial  on patients with metastatic pancreatic cancer. See “Clinical 
Programs” below. 
V-DOS47 
 
V-DOS47 is the second immuno-oncology drug candidate derived from the Company’s DOS47 technology platform. V-DOS47 is 
an antibody-DOS47 conjugate that targets the vascular endothelial growth factor 2 receptor (VEGFR2). VEGFR2 is overexpressed 
in breast carcinoma compared with benign breast tissue. In patients with highly estrogen receptor positive (ER+) forms of breast 
cancer, the efficacy of tamoxifen treatment negatively correlates with VEGFR2 expression.

Clinical programs 
 
The Company has commenced four clinical studies under the L-DOS47 program. Three clinical studies involve the treatment of 
NSCLC: A Phase I combination study (LDOS001) conducted in the U.S., a Phase I/II monotherapy study concluded in Poland 
(LDOS002), and a Phase II combination study running in Eastern Europe (LDOS003). A fourth clinical study, a Phase Ib/II study 
(LDOS006) investigating the treatment of metastatic pancreatic adenocarcinoma, received regulatory approval.   
 
LDOS001 – A Phase I combination therapy trial in lung cancer 
 
LDOS001 was a Phase I, open label, dose escalation study of L-DOS47 in combination with standard doublet therapy of 
pemetrexed/carboplatin in patients with stage IV (TNM M1a and M1b) recurrent or metastatic non-squamous NSCLC. Patients 
received standard of care doses of pemetrexed [500 mg/m2] and carboplatin [AUC6], respectively, on Day 1 of a 3-week cycle, in 
combination with L-DOS47 (starting dose 0.59 µg/kg), administered weekly. The objective of the study design was to evaluate 
safety and tolerability, as well as determine the maximum tolerated dose (“MTD”) of L-DOS47, in combination treatment. 
 
Fourteen (14) patients were enrolled across six dosing cohorts, starting at 0.59 and increasing up to 9.0 µg/kg. The MTD was not 
achieved as none of the patients experienced any dose-limiting toxicity (“DLT”). Fifty percent (50.0%) of patients experienced at 
least one treatment emergent adverse event assessed as study drug-related, with 14.3% of patients experiencing at least one 
grade 3/4 drug-related toxicity. Although the study was not designed specifically to assess efficacy, preliminary results showed 
that of 12 patients evaluable for efficacy, five patients (41.7%) had a partial response (“PR”), four patients (33.3%) experienced 
stable disease (SD) and three patients (25.0%) had progressive disease (“PD”). The objective response rate was 41.7%, with a 
median duration of 187 days, and a clinical benefit rate of 75.0% with a median duration of 141 days. Additional reports on L-
DOS47 pharmacokinetics and immunogenicity have been completed, with the final Clinical Study Report issued on December 13, 
2021. A manuscript was accepted for publication in Journal of Thoracic Oncology Clinical Research Reports on September 2, 
2022 and currently undergoing final copy and formatting. 
 
L-DOS47, in combination with pemetrexed/carboplatin, was well tolerated with promising anti-tumour activity against non-
squamous NSCLC.

LDOS002 – A phase I/II monotherapy trial in lung cancer 
 
LDOS002 was a Phase I/II open-label, non-randomized, dose escalation study of L-DOS47 as a monotherapy in adult subjects 
with inoperable, chemo-naïve or refractory Stage IIIb or IV non-squamous NSCLC. The primary objectives of the Phase I portion 
of the study were to evaluate safety and tolerability of ascending doses of L-DOS47 and define the MTD. Patients received weekly 
doses of L-DOS47, administered as an intravenous infusion over 14 days, followed by seven days rest (with one treatment cycle 
occurring over three weeks). 
 
Despite a total of 55 patients being dosed across 16 dose levels ranging from 0.12 up to 13.55 μg/kg, the MTD was not reached. 
There was only one single DLT of spinal/bone pain reported at the 5.76 μg/kg dose level. The weekly dosing schedule of L-DOS47 
for all doses up to 13.55 μg/kg was otherwise well tolerated and most adverse events reported were typical of the population under 
study. L-DOS47 did not elicit a dose-dependent release of cytokines at doses up to13.55μg/kg. Time of maximum observed 
plasma drug concentration after dosing (“Tmax”) was consistent across dose levels and treatment cycles, occurring within the first 
hour following the L-DOS47 infusion. There were no safety issues beyond those already observed in pre-clinical toxicology studies 
or expected in the population of patients being studied. 
 
A dose response trend was observed when comparing the percentage of patients who were progression-free at 16 weeks across 
dose ranges, according to Response Evaluation Criteria in Solid Tumours (“RECIST”) version 1.1. A similar trend was observed 
when comparing the percentage of patients who had stable disease and had a reduction in target lesions.

L-DOS47 Monotherapy dose response in cohorts 
 
In the Phase II portion of the study, the objective was to make a preliminary assessment of efficacy for L-DOS47 given as 
monotherapy. Enrolling subjects in the same patient population as in Phase I, patients were dosed at 13.55µg/kg, twice weekly 
over 14 days, followed by seven days’ rest. A total of 21 patients were dosed in the first stage of the Phase II component of the 
study.  
 
Despite an intensified L-DOS47 monotherapy dosing regimen, evaluation of initial results did not yield ≥1 partial or complete 
response at any time point as defined by protocol. The Phase II component of the study did not proceed to Phase II, Stage 2 and 
the development of L-DOS47, as monotherapy treatment of non-squamous, NSCLC was discontinued. Based on the efficacy 
results of the Phase I/II monotherapy study, Helix is pursuing Phase II studies in combination with therapies that may benefit from 
the pH-modulating effects of L-DOS47 on solid tumours that express CEACAM6. 
 
LDOS003 – A Phase II combination therapy trial in lung cancer 
 
LDOS003 is a Phase II, open-label, randomized study of L-DOS47 in combination with vinorelbine/cisplatin vs vinorelbine/cisplatin 
alone in patients with lung adenocarcinoma. Vinorelbine/cisplatin chemotherapy combination in the U.S. has become infrequent 
due to the rapidly evolving treatment landscape and the growing prominence of immunotherapies such as Keytruda®. The 
Company commenced this study based on the use of vinorelbine/cisplatin chemotherapy combinations in Eastern European and 
Asian markets. 
 
The approved protocol called for patients receiving L-DOS47 to be dosed on days 1 and 8 of each 21-day treatment cycle, along 
with standard vinorelbine/cisplatin chemotherapy for a total of four treatment cycles. The study was divided into two parts. Part I 
applied a standard 3 + 3 algorithm for dose escalation to determine the L-DOS47 maximum tolerated dose when given in 
combination with vinorelbine/cisplatin. Cohorts of three patients were recruited into three dosing cohorts (6, 9 and 12 µg/kg). All 
patients at a given dosing cohort were to complete the first treatment cycle (3-week period) before escalation in subsequent 
patients were to proceed. The decision for escalation to the next dose level would be made after the safety data had been reviewed 
by the Trial Steering Committee (“TSC”). If a patient in any cohort experiences a DLT, an additional three patients would need to 
be enrolled, for a maximum of up to 18 patients in this initial dose escalation part of the study. 
 
In Part II, after the maximum tolerated dose of L-DOS47 in combination with vinorelbine/cisplatin has been determined, a further 
118 patients will be randomized (1:1) to receive L-DOS47 in combination with vinorelbine/cisplatin, or vinorelbine/cisplatin alone. 
Efficacy will be assessed by time to progression (time from first day of study drug administration to documented disease 
progression), response rate (proportion of patients with a best overall response of complete response and partial response 
according to RECIST v. 1.1), and overall survival (time from first day of study drug administration to death due to any cause). 
Monitoring will include radiological evaluations every second cycle. Safety and tolerability of L-DOS47 in combination will also 
continue to be evaluated. For all patients, treatment will continue either until the patient experiences disease progression, 
unacceptable toxicity, the patient withdraws consent or has completed four treatment cycles. 
 
Patient recruitment began in February 2019 but halted in April 2020. At the time, the first two cohorts (6 and 9 µg/kg) in Part I of 
the study had been completed. Two (2) patients had also been dosed in the third cohort, 12 µg/kg, but the cohort could not be 
completed due to a shortage in the required vinorelbine dosages from the manufacturer, which was expected to continue into 
2021. Consequently, the Company made the decision to terminate further recruitment, proceed to data analysis and not move 
forward with Part II of the study.  Completion of an abbreviated clinical study report may be delayed or no longer be possible, in 
light of subsequent covid restrictions and the recent geopolitical developments in Ukraine and the potential inability to access or 
verify certain key data that would permit the Company to prepare and finalize the clinical study report.

LDOS006 – A Phase Ib/II combination trial in pancreatic cancer 
 
The Company received FDA approval in August 2019 to initiate a new study of L-DOS47 in the treatment of pancreatic cancer. 
This is an open label, non-randomized study designed to evaluate the safety, tolerability and preliminary anti-tumour activity of L-
DOS47 in combination with doxorubicin in patients aged ≥ 18 years old with metastatic pancreatic cancer who have progressed 
on at least two prior treatment regimens. The trial was initiated in November 2019 and the first patient dosed in December 2019. 
 
The Phase Ib part of the study applies a standard 3 + 3 algorithm for dose escalation to determine the L-DOS47 maximum tolerated 
dose to use in combination with doxorubicin for the Phase II part of the study. Patients are recruited into three cohorts where each 
cohort receives weekly dose levels of L-DOS47, (starting at 3 µg/kg and potentially escalating to 6 and 9 µg/kg), in combination 
with a fixed dose of 20 mg/m2 of doxorubicin weekly, (or 15 mg/m2 as per the subsequently amended protocol), with four weeks 
making up one treatment cycle up to a maximum of six cycles. The decision for escalation to the next dose level will be made after 
all patients in a cohort have completed four weeks of combination treatment and the safety data have been reviewed by the Safety 
Review Committee of the Company. If a patient in any cohort experiences a dose limiting toxicity, an additional three patients will 
be enrolled, for a maximum of up to 18 patients in this initial dose escalation part of the study. A further protocol amendment was 
submitted to FDA on November 15, 2021 to increase up to 8 treatment cycles at the reduced doxorubicin dose level of 15 mg/m2, 
with discretion to continue additional cycles at the discretion of the investigator. 
 
The Phase II part of the study will focus on evaluating preliminary anti-tumour activity, as well as continuing to evaluate safety and 
tolerability of L-DOS47 in combination with doxorubicin. A further 11 additional patients will be enrolled in this phase of the study. 
Patients will be initiated on the L-DOS47 dose determined in Phase I, in combination with 20 mg/m2 doxorubicin as per the original 
protocol or 15 mg/m2 as per the subsequently amended protocol, with tumour marker carbohydrate antigen 19-9 (CA19-9) 
measurements at each treatment cycle, and radiological assessments every two treatment cycles. Tumour response will be 
assessed according to RECIST version 1.1. Safety will be assessed by reported adverse events (AEs), serious adverse events 
(SAEs), physical exams, vital signs, Karnofsky Performance Status, electrocardiogram (ECG), echocardiogram (ECHO)/multi-
gated acquisition scan (MUGA), clinical laboratory evaluations (hematology, chemistry, coagulation and urinalysis), and anti-L-
DOS47 antibody levels.  
 
A total of fourteen (14) patients have been dosed with L-DOS47 in combination with doxorubicin.  Six (6) patients were dosed 
under the original protocol where patients were initiated on L-DOS47 in combination with 20 mg/m2 doxorubicin, three (3) of whom 
withdrew due to disease progression prior to completing the required 4-week cycle in order to be included in the evaluation for 
dose escalation. Of the remaining three (3) patients, one patient experienced a DLT attributed to doxorubicin and as a result, a 
protocol amendment adjusting the starting chemotherapy dose was submitted to FDA on December 23, 2020, and patient 
screening resumed on January 25, 2021. Due to slower enrolment related to challenges resulting from COVID-19 pandemic 
measures, two additional sites were opened for recruitment in March and April 2021. 
 
Under an amended protocol where patients were initiated on L-DOS47 in combination with 15 mg/m2 doxorubicin, the first three 
(3) patients dosed at the lowest L-DOS47 dosing cohort (3 µg/kg) resulted in one patient experiencing a serious adverse event 
(thromboembolic event – pulmonary emboli). As this event was initially assessed by the investigator as probably related to L-
DOS47, thereby meeting the criteria for a DLT, the cohort was expanded and a further 5 patients have since been dosed. Two 
patients discontinued from the trial prior to completing the required 4-week cycle in order to be included in the evaluation for dose 
escalation due to adverse events unrelated to study treatment. Of the remaining three patients, one discontinued after two 
treatment cycles due to disease progression, one discontinued in the sixth treatment cycle with stable disease observed for at 
least 4 treatment cycles, and one patient discontinued after the first treatment cycle due to an SAE (atrial fibrillation) that met 
criteria for DLT, based on initial investigator assessment. Sponsor physician disagrees with initial causality assessment due to 
patient’s complex medical/cardiac history. Further medical records were compiled and a complete review of all safety data from 
the first dosing cohort was conducted January 19, 2022. The first event, pulmonary emboli, which was initially identified as a DLT 
due to causality relationship, was subsequently revised to be unrelated to study treatment due to the emergence of additional 
relevant medical history prior to study entry. With a total of six (6) patients dosed, one (1) DLT event, the investigator group 
recommended to move forward with dose escalation to the next dosing level (6 µg/kg) 
 
On March 3, 2022, Helix submitted an additional protocol amendment to the FDA, updating exclusion criteria to further restrict 
patients with cardiac medical histories that would put them at higher risk of adverse events from doxorubicin treatment, which is a 
chemotherapy agent with known cardiotoxicities. On May 5, 2022, patient screening re-opened for dosing cohort 2 (6 µg/kg). 
Three (3) patients to date have entered into treatment, with one subject having completed the DLT period, one subject still in 
treatment during the DLT period, and one subject early terminating prior to completing the DLT period and requiring replacement. 
One additional patient is currently in screening. 
 
Given the Company’s limited current cash resources and the possibility of not being able to obtain additional financing on a timely 
basis, the Company may be required to reduce, delay or cancel one or more of its planned research and development programs, 
including clinical studies. 
 
Manufacturing 
 
L-DOS47 is an immunoconjugate drug composed of single chain antibody molecules specific for CEACAM6 that are cross-linked 
with a purified urease derived from the Jack Bean plant (Canavalia ensiformis).  

11 
 
 
The urease component is extracted from Jack Beans through a multistage process that yields an enzyme with high activity and 
purity. The llama-derived recombinant antibody is manufactured in E. coli and the purified antibodies are covalently linked to the 
urease enzyme by a chemical cross-linker into L-DOS47 drug substance. The drug substance is filled and lyophilized into the final 
L-DOS47 drug product for use in the clinic. The Company has extensively characterized L-DOS47 and maintains a comprehensive 
analytical program for the drug substance, drug product, and the urease and antibody intermediates. 
 
A Polysorbate 80, 1% w/w injection, as diluent is co-mixed with L-DOS47 prior to administration to prevent protein adsorption to 
the saline bags and IV tubing that are used to administer the drug to patients in the clinic. 
 
Manufacturing, release, and stability testing of L-DOS47 and the Polysorbate 80, 1% diluent is currently conducted by contract 
manufacturing organizations (“CMOs”) and contract testing laboratories (“CTLs”) in the U.S and Canada. The Company requires 
all CMOs and CTLs to maintain compliance with current GMP and to be licensed by the national regulatory authority in their 
jurisdiction. Company employees and consultants provide technical, quality, and regulatory oversight for all operations related to 
L-DOS47 production. Currently, the Company has service and quality agreements with several CMOs/CTLs for clinical-stage 
manufacturing, testing, and release of the L-DOS47 drug substance and drug product and the Polysorbate 80, 1% diluent. 
 
The Company’s supply of L-DOS47 drug product continues to be subjected to stability assays according to ICH Q1A (R2) 
guidelines. The stability program for the lot in clinical use has been resupplied and the stability protocol will be extended as long 
as the product continues to meet specifications. The batch has been found to be stable at least through the last testing point (90M, 
May 2022). If the product goes Out-of-Specification (OOS) at the real-time storage condition (2-8ºC) for two consecutive pulls 
before the final time point, further testing and clinical use may be discontinued. 
 
The CMO that manufactured the L-DOS47 drug substance batch that has been used in the Company’s clinical studies informed 
the Company in early 2019 that it would no longer be able to manufacture L-DOS47. In September 2019, the Company signed an 
agreement with another CMO to reprocess an older drug substance batch the Company had kept in reserve. The Company 
completed the reprocessing of the drug substance batch in June 2020, and after quality control testing and release, the drug 
substance was transferred to another CMO to complete the fill/finish process. After lyophilization, which was completed in early 
2021, the drug product lot was placed on a 36M stability program which may be extended if warranted by real-time stability data. 
If the product goes OOS at the real-time storage condition (2-8ºC) for two consecutive pulls before the final time point, further 
testing may be discontinued. The new batch completed 12M stability testing in January 2022 with the next time point in progress 
as of August 2022. The Company has another older batch of L-DOS47 drug substance which requires reprocessing to produce 
drug product. If this lot is successfully reprocessed it can be used for to produce a new lot of drug product in the event it is needed.  
 
The Company has also been in discussion with another CMO to plan out a technology transfer program to manufacture batches 
of L-DOS47 drug product. As of the date of this MD&A, no commitment has been made. 
 
If any of the stability assays for the current batch or new production batch do not meet acceptance criteria, the Company’s clinical 
studies and any planned research and development programs would likely face delays and possibly be cancelled, which could 
impair the current and future value of the business. See “Risk Factors”. 
 
Product focus and strategy 
 
The Company continues to focus on the development, commercialization &/or partnership of L-DOS47 as a potential therapy for 
NSCLC and pancreatic cancer but at the same time is evaluating the current clinical strategy to determine if the Company’s L-
DOS47 pipeline can be expanded into other indications, such as colon cancer as well as head and neck cancer. As a result, the 
Company retained the services of Lumanity to assess the viability of the Company’s drug product candidate with a focus on 
identifying value propositions and positioning strategies that would enable clinical adoption of L-DOS47, including obtaining broad 
clinical development key opinion leader input on the positioning of possible combination therapies and the prioritization of current 
and/or any additional clinical indications. 
 
Interviews conducted by Lumanity with key opinion leaders since its engagement with the Company helped validate the utility of  
the clinical work completed by Helix to date and has assisted the Company identify additional opportunities to further strengthen 
and de-risk the Company's clinical drug candidate program, including optimal selection of patients for trials (stratification) based 
on objective biomarkers, among other criteria. The Company anticipates that these activities may assist to initiate dialogue with 
potential market participants in cancer treatment, and that the additional preclinical data obtained could further enhance the 
Company's clinical program design. 
 
The Company continues to believe that its growth and future prospects are mainly dependent on the success of its DOS47 drug 
product candidates. 
 
NSCLC 
 
 
The Company completed the LDOS001 Phase I LDOS-47 pemetrexed/carboplatin combination study clinical report and 
submitted a final annual report to FDA on April 4, 2022. /Results were updated in t www.clinicaltrials.gov portal in June 
2022.

 
The Company continues to be in discussion with the CRO over billings concerning the LDOS003 Phase I LDOS-47 
vinorelbine/cisplatin combination study.  The recent escalation of war in Ukraine, where the Company enrolled virtually 
all its patients in this clinical study, has complicated matters. As of the date of this MD&A, it is uncertain as to when the 
clinical study reports will be completed, if at all. 
 
Pancreatic 
 
 
COVID-19 materially hindered patient enrollment in the Company’s LDOS006 Phase Ib doxorubicin combination study, 
resulting in the Company adding two new clinical sites early in calendar year 2021.  This clinical study was also impacted 
with two adverse events, which resulted in the expansion of the number of patients previously forecasted to complete the 
Phase Ib portion of the study.  The Company is currently in Cohort II of the Phase Ib portion of the clinical study. The 
Company projects to complete Phase Ib provided certain criteria are satisfied, expecting to move into the Phase II portion 
of the clinical study by early 2023. 
 
Commercialization 
 
The Company’s DOS47 commercialization objective is to eventually enter into a strategic partnering alliance with a large 
pharmaceutical company, on an individual or multiple drug candidate basis, such as L-DOS47 or any potential new DOS47 drug 
product candidate. The intention of Company is to enter a structured process that will include preparing the Company to have 
discussions with potential partners, engaging in dialogue with a targeted group of qualified partners and licensees, and entering 
negotiations on a prospective partnership, alliance or licensing transaction. In the meantime, the Company will continue to gather 
as much value-adding clinical data/findings, which demonstrate the safety and efficacy of L-DOS47 in patients or any other new 
potential DOS47 drug candidate, so as to maximize value for shareholders when entering into a strategic partnering alliance. 
 
Market and competition 
 
NCSLC 
 
Based on information published in “Key Statistics for Lung Cancer” by the American Cancer Society (www.cancer.org) in January 
2022, lung cancer accounts for approximately 25% of all cancer deaths and is by far the leading cause of cancer death among 
men and women in the U.S. It was estimated that in 2022 there would be over 236,740 new lung cancer cases and 130,180 people 
may die from the disease in the United States. Of these cases, over 84% were anticipated to be of the non-small cell lung cancer 
(NSCLC) type. 
 
The treatment options for metastatic NSCLC have changed significantly in the last few years due to the clinical success of 
immunotherapies such as immune checkpoint inhibitors that target Programmed Death 1 (“PD-1”) or its ligands. However, a 
significant percentage of patients do not respond to current therapies resulting in an urgent need for additional therapeutic options. 
Treatment options for metastatic NSCLC have changed significantly in the last few years due to the clinical success of 
immunotherapies such as immune checkpoint inhibitors that target PD-1 or its ligands. On March 4, 2015, the FDA approved 
Nivolumab, the generic name for the trade drug named Opdivo®, which targets PD-1 for the treatment of metastatic squamous 
NSCLC with progression on or after platinum-based chemotherapy. On October 2, 2015, the FDA granted accelerated approval 
for Pembrolizumab, the generic name for the trade drug named Keytruda®, which targets PD-1 to treat patients with advanced 
metastatic NSCLC with Tumours that express PD-L1 whose disease has progressed after treatment.  
 
As of March 2017, the FDA had approved seven checkpoint inhibitor drugs: ipilimumab (Yervoy®), pembrolizumab (Keytruda®), 
nivolumab (Opdivo®), atezolizumab (Tecentriq®), avelumab (Bavencio®), durvalumab (Imfinzi®) and cemiplimab (Libtayo®).  All 
but avelumab and cemiplimab are being used for the treatment of NSCLC. 
 
Pancreatic cancer 
 
Pancreatic cancer remains a deadly disease of significant unmet medical needs. In “Key Statistics for Pancreatic Cancer” dated 
January 2022, the American Cancer Society estimated that in 2022, 62,210 people would be diagnosed with the disease in the 
US with 49,830 deaths. The most common type of pancreatic cancer is exocrine in nature and approximately 95% of these 
exocrine cancers are adenocarcinomas. 
 
Treatment options for late-stage metastatic pancreatic cancer patients are limited. Surgery and radiation are used only for 
symptom relief and chemotherapy remains the primary mode of therapy. Gemcitabine is widely used either alone or in combination 
with erlotinib (Tarceva), capecitabine, cisplatin or nab-paclitaxel. Other chemo-cocktails such as FOLFIRNOX are also possible 
depending on patient tolerability to such cocktails and physician choice of best suitable care. If these lines of therapy are not 
effective, other combinations such as oxaliplatin and fluoropyrimidine may be used. 
 
Although checkpoint therapy has been shown to be beneficial in certain lung cancers and melanoma, checkpoint therapy clinical 
studies in pancreatic patients have largely been unsuccessful. While the exact reasons are still to be elucidated, the unique 
structural and immune environment associated with pancreatic cancer may underlie the lack of success with antibody-based 
immunotherapies. See “The Company faces risks in connection with competition and technological change” under the heading 
“Risk Factors”.

SUMMARY OF QUARTERLY RESULTS 
 
The Company reported a net loss and total comprehensive loss of $6,563,000 for the year ended July 31, 2022  (July 31, 2021 - 
$8,038,000). 
 
The following table depicts selected quarterly data previously reported for the last eight quarters (thousands of $, except per share 
data): 
 
 
 
In Q1 fiscal 2021, the Company lost control of its former subsidiary and as a result deconsolidated its former subsidiary in its 
financials going forward.  Net loss and comprehensive loss decreased significantly in Q1 of fiscal year 2021 due to a gain from 
discontinued operations of $2,162,000 recorded in that quarter. Cash increases in Q4 and Q2 in fiscal year 2021 are due to (i) the 
successful closings of a two-tranche private placement of units on December 4 and 30, 2020 for total gross proceeds of $4,100,000 
and (ii) the closing of the First Tranche of the convertible debenture funding agreement with Lind for gross proceeds of $3,500,000. 
Cash increase in Q3 in fiscal year 2022 is due the successful closing of a private placement financing for gross proceeds of 
$1,001,000 from the issuance of 3,850,000 common shares at a price of $0.26 per common share and the closing of a private 
placement financing for net proceeds of $2,002,000 from the issuance of 7,700,000 common shares at a price of $0.26 per 
common share. Cash increase in Q4 is due to shareholders exercising 12,346,938 warrants at a special reduced price of $0.26 
per share which the Company applied and received approval from the Toronto Stock Exchange. The exercise of the warrants 
generated a total of $3,210,204.  Capital raised by the Company has gone towards working capital and research and development 
expenditures associated with the Company’s pre-clinical and clinical programs.   
 
On September 12, 2022, the Company applied to the TSX to price protect a proposed $5 million financing of common shares at 
a price of $0.18 per share. The TSX granted a price protection letter on September 14, 2022, and the conditional approval of the 
placement on September 26, 2022. As of October 31, 2022, the Company has received a total of $4,644,000 in subscription 
receipts related to this financing with insiders subscribing for $270,000. The closing of the private placement is expected November 
1, 2022.

Research and development expenditures for the year ended July 31, 2022, when compared to the year ended July 31, 2021, were 
lower by $1,336,000. The decrease in spending is mainly the result of lower expenditures associated with research and 
development activities by 23% partially offsetting the increases in consulting services and stock-based compensation, which were 
higher due to expense of stock options granted to consultants.  When compared to the year ended July 31, 2021, the Company 
also spent less on salaries and benefits by $195,000 or 15% while consulting and stock-based compensation were higher by 
$943,000.  
 
The Company hired biotechnology consultants to assess the Company’s drug product candidate with a focus on identifying value 
propositions and positioning strategies that would enable clinical adoption of L-DOS47. See “Overview” above for additional 
information. 
 
Operating, general and administration 
 
Operating, general and administration expenses for the year ended July 31, 2022, totalled $ 1,496,000 (2021 – $ 3,251,000).

Operating, general and administration expenditures for the year ended July 31, 2022, when compared to the year ended July 31, 
2021, were lower by $1,755,000 or 54%. 
 
Since May 2022, the Company has made significant efforts to control and reduce its overheads expenditures. This included closing 
its headquarters at Richmond Hill Ontario and moving it to Grove Corporate Services offices “(Grove”) in downtown Toronto. The 
Company hired Grove to perform accounting and corporate secretarial services following the resignation of its previous CFO in 
May 2022. The savings apply to various activities including salaries, rent, legal, and other operational expenditures. Further 
measures are being taken which will result in more reductions in the next quarter. 
 
Some expenditures in the comparative period relates to the Company’s attempt to raise additional capital as part of a qualifying 
transaction to list its common shares on a U.S. stock exchange, the termination of an investor relations agreement with ACM 
Alpha Consulting Management EST (“ACMest”) and stock-based compensation expenses of stock options granted to directors. 
 
Several factors materialized that resulted in the Company abandoning its plans to list on a U.S. stock exchange. These include 
but are not limited to the increase in the percentage ownership of the Common Shares by new insiders and a decline in the price 
of the Common Shares making it extremely challenging for the Company to leverage the Multijurisdictional Disclosure System.

Loss of control and deconsolidation of subsidiary – discontinued operations 
 
At July 31, 2020, the Company’s investment in HIO was classified as held for sale and was presented as discontinued operations 
On September 3, 2020, HIO completed a direct financing with an arm’s length party.  As a result of the financing, the Company’s 
ownership in HIO was diluted down to 29.89% and the Company determined that it had lost control of HIO during the year ended 
July 31, 2021. As the Company’s interest allows the Company to exert significant influence over HIO, the Company’s remaining 
interest was accounted for as an interest in associate using the equity method.  The difference between the carrying value of the 
net assets of HIO and non-controlling interest and the value assigned to the shares of $2,231,000 was recognized as a gain on 
loss of control of subsidiary in the year ended July 31, 2021.  
 
On November 9, 2020, the Company announced that it had signed a definitive share purchase agreement with CAIAC Fund 
Management AG (“CAIAC”), as designated trustee of HIO Fund, to purchase the Company’s remaining holdings in HIO for gross 
proceeds of PLN 6,700,000 (CDN$2,308,000) (the “HIO Disposition”). The HIO Disposition closed on December 22, 2020 and the 
Company incurred transaction fees of 12.5% of the proceeds amounting to $288,500 payable to ACMest. As of the date of this 
MD&A, the Company does not hold any equity in HIO. See Loss of control and deconsolidation of subsidiary – discontinued 
operations below.

Significant projects 
 
For a summary of the Company’s significant projects that have not yet generated revenue, please see “Overview” above. 
 
CRITICAL ACCOUNTING ESTIMATES 
 
The preparation of the annual financial statements in conformity with IFRS requires management to make judgments, estimates and 
assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, revenue and 
expenses and the related disclosures of contingent assets and liabilities and the determination of the Company’s ability to continue 
as a going concern. Actual results could differ materially from these estimates and assumptions.  The Company reviews its 
estimates and underlying assumptions on an ongoing basis.  Revisions are recognized in the period in which the estimates are 
revised and may impact future periods. 
 
The Company has also assessed the impact of COVID-19 on estimates and critical judgement.  Although the Company expects 
COVID-19 related disruptions to continue throughout the 2022 fiscal year, the Company believes that the long-term estimates and 
assumptions do not require significant revisions. Although the Company determined that no significant revisions to such estimates, 
judgements or assumptions were required, the pandemic is fluid and given the inherent uncertainty at this time, revisions may be 
required in future periods to the extent that the negative impacts on the Company’s business operations arising from COVID-19 

16 
 
continue or become worse.  Any such revision could result in a material impact on the Company’s financial performance and 
financial condition. 
 
The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the 
Company’s annual financial statements have been set out in Note 1 of the Company’s annual financial statements for the years 
ended July 31, 2022 and 2021. 
 
SIGNIFICANT ACCOUNTING POLICIES 
 
The significant accounting policies used in preparing the Company’s consolidated financial statements are described in Note 2 of 
the Company’s annual financial statements for the year ended July 31, 2022 and 2021, except for those related accounting policies 
and methods of computation related to any new accounting standards and pronouncements. 
 
NEW ACCOUNTING STANDARDS AND PRONOUNCEMENTS NOT YET ADOPTED 
 
There are no new accounting standards and pronouncements issued but not yet effective up to the date of issuance of the 
Company's annual financial statements that are expected to have a material impact on the Company. 
 
LIQUIDITY AND CAPITAL RESOURCES 
 
Since inception, the Company has mainly relied on financing its operations from public and private sales of equity. The Company 
does not have any credit facilities and is therefore not subject to any externally imposed capital requirements or covenants. The 
Company manages its liquidity risk by continuously monitoring forecasts and actual cash flow from operations and anticipated 
investing and financing activities. 
 
The Company reported a net loss and total comprehensive loss for the years ended July 31, 2022 $6,563,000 (July 31, 2021- 
$8,038,000).  As at July 31, 2022 the Company had working capital of $284,000, shareholders’ equity of $319,000 and a deficit of 
$195,117,000. As at July 31, 2021, the Company had working capital of $144,000, shareholders’ deficiency of $1,393,000 and a 
deficit of $188,554,000. 
 
During the year ended July 31, 2021, the Company completed two private placements resulting in the issuance of 8,200,000 units 
(“Units”) at a price of $0.50 per Unit for aggregate gross proceeds of $4,100,000 ($3,561,000 net of issue costs).  The sale of the 
Units resulted in the issuance of an aggregate of 8,200,000 Common shares and 8,200,000 Warrants, with each such Warrant 
entitling the holder thereof to purchase one Common Share at an exercise price of $0.70 for a period of five years from the date 
of issuance. 
 
On March 11, 2022, the Company closed a private placement financing for gross proceeds of $1,001,000 from the issuance of 
3,850,000 common share at a price of $0.26 per common share. On April 21, 2022, the Company closed a private placement 
financing for net proceeds of $2,002,000 from the issuance of 7,700,000 common shares at a price of $0.26 per common share. 
 
On April 13, 2022, the Company announced that it has received conditional approval from the Toronto Stock Exchange to extend 
its previously announced Early Warrant Exercise Incentive Program from April 28, 2022, to May 31, 2022. The Incentive Program 
is a period during which holders of the Company’s eligible common share purchase warrants (“Eligible Warrants”) may take 
advantage of a temporary reduction in the exercise price of the Eligible Warrants to a price of C$0.26. The Eligible Warrants 
include an aggregate of 49,806,469 warrants that if exercised at the Incentive Exercise Price will result in the Company receiving 
gross proceeds of up to $12,949,682. During the year ended July 31, 2022, 12,346,938 warrants were exercised for a total 
subscription amount of $3,210,204.  
 
On May 11, 2021, the Company entered into a definitive convertible security funding agreement (“the Funding Agreement”) with 
Lind Global Macro Fund, LP, a New York based institutional investment fund managed by The Lind Partners, LLC (collectively 
“Lind”). The Company closed the first tranche under the Funding Agreement on May 13, 2021 for gross proceeds of $3,500,000 
(the “First Tranche”). In connection with the closing of the First Tranche, the Company issued (i) an 8.75% convertible note (a 
“Convertible Security”) with a two-year term and a fair value of $4,112,500 and (ii) an aggregate of 1,957,056 Warrants exercisable 
into Common Shares until May 12, 2025, at an exercise price of $1.0283 per Common Share and classified as equity instruments. 
The Convertible Security issued under the First Tranche accrues a simple interest rate obligation of 8.75% per annum on the 
amount funded, being $3,500,000, which interest is prepaid and attributed to the face value of the Convertible Security. The 
Company also paid Lind a 3% commitment fee on the amount funded under the First Tranche, as well as under any second 
tranche, which as of the date of this MD&A has not yet been completed. 
 
Each Convertible Security issuable under the Lind Agreement has a two-year term from the date of issuance and accrues a simple 
interest rate obligation of 8.75% per annum on the amount funded, where interest is prepaid and attributed to the face value of 
each Convertible Security upon issuance. Lind is entitled to convert the Convertible Securities into Common Shares over the term 
of the applicable Convertible Security, subject to certain limitations, at a conversion price equal to 85% of the five-day trailing 
volume-weighted average price (“VWAP”) of the Common Shares prior to the notice date of conversion provided to the Company 
by Lind. The Lind Agreement includes certain restrictions on the maximum face value of each of the Convertible Securities that 
may be converted in any particular month. In addition, the Company has the option to buy-back 66.7% of the Convertible Securities 

17 
 
in cash at any time with no penalty, subject to the option of Lind to convert up to 1/3 of the face value of the applicable Convertible 
Security into Common Shares at the time of such buy-back. If the Convertible Security is repaid by the Company within 180 days 
of issuance, the face value amount owed will be reduced pursuant to the terms of the Lind Agreement. Lind will also be entitled to 
accelerate its conversion right to the full amount of the face value or demand repayment of the face value in cash upon a default 
and other designated events as set out in the Lind Agreement. To the extent that the full-face value of a Convertible Security has 
not been converted at the maturity date of the applicable Convertible Security, the outstanding balance of such face value shall 
be to be repaid to Lind by the Company in cash. 
 
The Funding Agreement contains certain ongoing covenants of the Company typical of an agreement of its nature.  In the event 
of certain defaults by the Company under the Funding Agreement, Lind has the right, upon notice to the Company, to accelerate 
the conversion of the face value of any outstanding Convertible Security or demand repayment of such face value in cash and 
terminate the Funding Agreement. No such notice has been delivered to the Company as at the date of these consolidated financial 
statements. A copy of the Funding Agreement is available on SEDAR at www.sedar.com. 
 
In the year ended July 31, 2022, Lind converted $1,645,000 of the face value of the Convertible Security issued under the First 
Tranche into 6,764,798 common shares of the Company at an average deemed price of $0.1934 per common share. As of July 
31, 2022, Lind has converted an aggregate of $1,645,000 of the face value of the Convertible Security issued under the First 
Tranche into an aggregate of 6,794,798 common of the Company at an average deemed price of $0.243 per common share.  In 
August 2022, Lind further converted $405,625 of face value into an aggregate 2,507,329 shares at an average deemed price of 
$0.1618 per common share. On August 30, 2022, the Company announced that it had completed the buyback of the outstanding 
amount of the convertible security funding agreement with Lind at a cost of C$2,061,875. 
 
 See Note 7 – Convertible note payable for additional information. 
 
 
 
In order for the Company to advance the currently planned preclinical and clinical research and development activities, its 
collaborative scientific research programs and pay for its overhead costs, the Company will need to raise approximately 
$11,000,000 through to the end of fiscal 2024. The Company projects an average monthly fixed overhead spend of approximately 
$230,000. This amount does not include the costs related to any of the Company’s third-party activities such as clinical studies, 
collaborative research activities and contract manufacturing. 
 
The Company currently has three clinical studies (see Research and Development Activities above for additional information) in 
various stages. The Company has completed the clinical study report for LDOS001 and submitted a final annual report to the FDA 
in April 2022 and update the result into the www.clinicaltrials.gov portal in June 2022. The Company is forecasting approximately 
$10,000 to finalize reporting. 
 
The Company previously forecasted LDOS003 as a large, randomized study but concluded that it would not move forward with 
the randomized portion of the study unless the Company entered into a co-development partnership with a third party. The 
Company was working to complete the study and report which has been delayed due to administrative disagreement as a result 
of overbilling by the clinical research organization overseeing the program. The recent escalation of war in Ukraine, where the 
Company enrolled virtually all its patients in this clinical study, has complicated matters. As at the date of this MD&A, it is uncertain 
as to when the clinical study reports will be completed, if at all. The Company is currently projecting $486,000 to complete and 
wind up the clinical study.  
 
The Company received IND approval by the FDA to conduct a Phase Ib/II study (LDOS006) in the U.S., L-DOS47 in combination 
with doxorubicin, for previously treated advanced pancreatic cancer. Patient enrollment commenced December 2019. COVID-19 
impacted patient enrollment resulting in the Company adding two additional clinical sites this year. The Company is forecasting a 
cost of approximately $4,042,000 through to December 2023 to complete both the Phase Ib and Phase II portion of the trial.

Certain conditions need to be achieved in order for the Company to be able to progress through to the Phase II portion of the trial.  
Of the forecasted $4,826,000, the portion attributable to the Phase II is estimated to be approximately $2,603,000. 
 
The Company is forecasting manufacturing expenditures of approximately $2,222,000 through to the end of fiscal 2024 in support 
of the Company’s drug development program. The Company previously forecasted a manufacturing technology transfer to a new 
manufacturer with a scaled-up production in anticipation of having sufficient supply for a contemplated pivotal trial and a new 
clinical study of L-DOS47 in combination with an immune-oncology drug. The Company has since produced a new batch of drug 
product from previous drug substance providing additionally sufficient supply for the Company’s current clinical program, provided 
stability assays continue to meet protocol standards. 
 
The Company is currently not forecasting any collaborative research expenditures. 
 
The Company’s cash reserves of $3,252,000 as at July 31, 2022 are insufficient to meet anticipated cash needs for working capital 
and capital expenditures through the next twelve months, nor are they sufficient to see planned research and development 
initiatives through to completion. Additional funds are required to advance the Company’s clinical and preclinical programs and 
deal with future working capital requirements. To the extent that the Company does not believe it has sufficient liquidity to meet 
its current obligations, management considers securing additional funds, preferably through the issuance of equity securities of 
the Company, to be critical for its development needs. The Company may also consider other forms of raising funds, such as the 
issuance of debt which may or may not include a conversion of equity in the Company. 
 
The Company’s long-term liquidity depends on its ability to raise funds from various sources, which depends substantially on the 
success of its ongoing research and development programs, economic conditions and the state of the biotech industry. 
 
Accessing the capital markets can be particularly challenging for companies that operate in the biotechnology industry. While the 
Company has been able to raise equity financing in recent years, there can be no assurance that additional funding by way of 
equity financing will continue to be available. Any additional equity financing, if secured, would result in dilution to the existing 
shareholders and such dilution may be significant. The Company may also seek additional funding from or through other sources, 
including technology licensing, co-development collaborations, mergers and acquisitions, joint ventures, and other strategic 
alliances, which, if obtained, may reduce the Company’s interest in its projects or products or result in significant dilution to existing 
shareholders. The Company may also seek additional funding from government grants. There can be no assurance, however, 
that any alternative sources of funding will be available. The failure of the Company to obtain additional financing on a timely basis 
may result in the Company reducing, delaying or cancelling one or more of its planned research, development and/or marketing 
programs, including clinical trials, further reducing overhead, or monetizing non-core assets, any of which could impair the current 
and future value of the business or cause the Company to consider ceasing operations and undergoing liquidation. 
 
Given the Company’s conclusion about the insufficiency of its cash reserves, significant doubt is cast about the Company’s ability 
to continue operating as a going concern. The continuation of the Company as a going concern for the foreseeable future depends 
mainly on raising sufficient capital, and in the interim, reducing, where possible, operating expenses (including making changes 
to the Company’s research and development plans), including the delay of one or more of the Company’s research and 
development programs, further reducing overhead and the possible disposition of assets. 
 
The Company needs to raise additional capital to further advance its clinical development program. 
 
Use of proceeds from the sale of securities in the past have been used for working capital, including funding the Company’s 
ongoing research and development activities.

FINANCIAL INSTRUMENTS 
 
Fair value hierarchy 
 
Financial instruments recorded at fair value on the balance sheet are classified using a fair value hierarchy that reflects the 
significance of the inputs used in making the measurements.  The fair value hierarchy has the following levels: 
 
 
Level 1 reflects valuation based on quoted prices observed in active markets for identical assets or liabilities; 
 
Level 2 reflects valuation techniques based on inputs that are quoted prices of similar instruments in active markets; 
quoted prices for identical or similar instruments in markets that are not active; inputs other than quoted prices used in a 
valuation model that are observable for that instrument; and inputs that are derived principally from or corroborated by 
observable market data by correlation or other means; and 
 
Level 3 reflects valuation techniques with significant unobservable market inputs. 
 
A financial instrument is classified to the lowest level of the hierarchy for which a significant input has been considered in measuring 
fair value.  The financial instrument in the Company’s annual financial statements, measured at fair value, is cash. 
 
Fair value 
 
The fair value of financial instruments as at July 31, 2022 approximates their carrying value because of the near-term maturity of 
these instruments. 
 
INTELLECTUAL PROPERTY 
 
The Company protects its intellectual property rights through a robust combination of patent, copyright, trademark and trade 
secrets as well as with confidentiality and invention assignment agreements.  
 
The Company seeks intellectual property protection in various jurisdictions around the world and owns patents and patent 
applications relating to products and technologies in the United States, Canada, Europe and other jurisdictions.

As of July 31, 2022, the Company had rights to 5 issued U.S. patents, which will expire between July 16, 2023 and January 22, 
2036 assuming all required fees are paid, 6 pending U.S. patent applications, 64 issued foreign patents, and 42 pending foreign 
patent applications. The Company’s patents and patent applications cover aspects of its current and future product concepts. 
Some of the pending foreign patent applications preserve an opportunity to pursue patent rights in multiple countries.  As of July 
31, 2022, the Company had one registered trademark in Canada. 
 
The Company also relies, in part, upon unpatented trade secrets, know-how and continuing technological innovation, and may in 
the future rely upon licensing opportunities, to develop and maintain our competitive position. The Company protects its proprietary 
rights through a variety of methods, including confidentiality and assignment agreements with suppliers, employees, consultants, 
and others who may have access to the Company’s proprietary information. 
 
While there is no active litigation involving any of the Company’s patents or other intellectual property rights and the Company has 
not received any notices of patent infringement, the Company may be required to enforce or defend its intellectual property rights 
against third parties in the future.  
 
Patents and other proprietary rights are very valuable to the Company and involve complex legal and factual issues. The Company 
has no assurance that any of its patent applications will result in the issuance of patents. Even issued patents may not provide the 
Company with a competitive advantage against competitors with similar technologies, or who have designed around the 
Company’s patents. Furthermore, the Company’s patents may be invalidated or found enforceable if challenged. Intellectual 
property laws vary from country to country which may result in varying levels of intellectual property protection.  
 
Because of the substantial length of time and expense associated with developing new products, the pharmaceutical, medical 
device, and biotechnology industries place considerable importance on obtaining patent protection for new technologies, products, 
and processes. The Company’s policy is to file patent applications to protect inventions, technology, and improvements that are 
important to the development of its business and with respect to the application of our products and technologies to the treatment 
of a number of diseases. The Company’s policy also includes regular reviews related to the development of each technology and 
product in light of its intellectual property protection, with the goal of protecting all key research and developments by patent. 
The Company will continue to seek intellectual property protection as appropriate and require our employees, consultants, outside 
scientific collaborators, and sponsored researchers to enter into confidentiality agreements with the Company that contain 
assignment of invention clauses outlining ownership of any intellectual property developed during the course of the individual’s 
relationship with the Company. 
 
Patents 
 
The Company currently owns several patents in respect of the DOS47 technology and has licensed patent rights from the NRC 
for the antibody component of L-DOS47. In addition to issued patents, the Company has filed several new patent applications 
around the world. 
 
OFF-BALANCE SHEET ARRANGEMENTS 
 
The Company has no material off-balance sheet arrangements. 
 
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 
 
The Company’s main objectives when managing capital are to ensure sufficient liquidity to finance research and development 
activities, clinical trials, ongoing administrative costs, working capital and capital expenditures.  The Company includes cash and 
components of shareholders’ equity, in the definition of capital.  The Company endeavours not to unnecessarily dilute shareholders 
when managing the liquidity of its capital structure. 
 
Market risk 
 
Market risk is the risk that changes in market prices, such as interest rates and foreign exchange rates, will affect the Company’s 
income or the value of its financial instruments. 
 
 
 

21 
 
Currency risk 
 
The Company has international transactions and is exposed to foreign exchange risks from various currencies, primarily the Euro 
and U.S. dollar.  In addition, foreign exchange risks arise from purchase transactions, as well as recognized financial assets and 
liabilities denominated in foreign currencies. 
 
Balances in foreign currencies are as follows, as at:

Any fluctuation in the exchange rates of the foreign currencies listed above could have an impact on the Company’s results from 
operations; however, they would not impair or enhance the ability of the Company to pay its foreign-denominated expenses.  
 
Credit risk 
 
Credit risk is the risk of a financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its 
contractual obligation. 
 
The table below breaks down the various categories that make up the Company’s accounts receivable balances as at:

$ 353,000 
 
Interest rate risk 
 
Interest rate risk is the risk that future cash flows of a financial instrument will fluctuate because of changes in interest rates, which 
are affected by market conditions.  The Company is exposed to interest rate risk arising from fluctuations in interest rates received 
on its cash.  The Company is not subject to any debt related interest rate risk. 
 
The Company manages its interest rate risk by maximizing the interest income earned on excess funds while maintaining the 
liquidity necessary to conduct its operations on a day-to-day basis.  Any investment of excess funds is limited to risk-free financial 
instruments.  Fluctuations in the market rates of interest do not have a significant impact on the Company’s results of operations 
due to the relatively short-term maturity of any investments held by the Company at any given point in time and the low global 
interest rate environment.  The Company does not use derivative instruments to reduce its exposure to interest rate risk. 
 
Liquidity risk 
 
Liquidity risk is the risk that the Company will not be able to meet its obligations as they come due.  Since inception, the Company 
has mainly relied on financing its operations from public and private sales of equity.  The Funding Agreement is subject to certain 
ongoing covenants of the Company that could affect the Company’s liquidity.  
 
The Company manages its liquidity risk by continuously monitoring forecasts and actual cash flow from operations and anticipated 
investing and financing activities. 
 
The Company’s cash reserves of $3,252,000 as at July 31, 2022 are insufficient to meet anticipated cash needs for working capital 
and capital expenditures through the next twelve months, nor are they sufficient to see the current research and development 
initiates through to completion.  To the extent that the Company does not believe it has sufficient liquidity to meet its current 
obligations, management considers securing additional funds primarily through equity arrangements to be of utmost importance. 
 
 

22 
 
 
 
The Company’s long-term liquidity depends on its ability to access the capital markets, which depends substantially on the success 
of the Company’s ongoing research and development programs, as well as economic conditions relating to the state of the capital 
markets generally.  Accessing the capital markets is particularly challenging for companies that operate in the biotechnology 
industry.

OUTSTANDING SHARE DATA 
 
The Company is authorized to issue 10,000,000 preferred shares. As of the date of this MD&A, the Company has nil preferred 
shares issued and outstanding. 
 
The Company is authorized to issue an unlimited number of Common Shares without par value. As at the date of this MD&A, the 
Company has 171,794,753 Common Shares issued and outstanding. 
 
As at the date of this MD&A, the Company had the following securities convertible into common shares outstanding:  
 
1. 
Warrants to purchase up to 43,472,231 Common Shares:   
2. 
Options to purchase up to 9,050,000 Common Shares; and   
 
DISCLOSURE CONTROLS AND PROCEDURES AND INTERNAL CONTROL OVER FINANCIAL REPORTING  
 
Management has designed the Company’s disclosure controls and procedures (“DC&P”) to provide reasonable assurance that all 
relevant information is gathered, recorded, processed, summarized and reported to the Chief Executive Officer and the Chief 
Financial Officer of the Company so that appropriate decisions can be made within the time periods specified in securities 
legislation regarding public disclosure by the Company in its annual filings, interim filings or other documents or reports required 
to be filed or submitted by it under securities legislation.  
 
Management has also designed internal controls over financial reporting (“ICFR”) to provide reasonable assurance regarding the 
reliability of the Company’s financial reporting and the preparation of its financial statements for external purposes, as applicable, 
in accordance with IFRS. Because of its inherent limitations, ICFR can provide only reasonable assurance and may not prevent 
or detect misstatements. Further, projections of any evaluation of effectiveness to future periods are subject to the risk that controls 
may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may 
deteriorate 
 
Management Report on ICFR and DC&P 
 
Management is responsible for establishing and maintaining adequate ICFR and has designed such ICFR to provide reasonable 
assurance regarding the reliability of financial reporting and the preparation and fair presentation of annual consolidated financial 
statements for external purposes in accordance with IFRS. The control system has been designed 
 
Management, including the Chief Executive Officer and Chief Financial Officer, does not expect that the Company’s ICFR will 
prevent all error and all fraud. A control system can provide only reasonable, not absolute, assurance that the objectives of the 
control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute 
assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations 
include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or 
mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or 
by management override of the control. The design of any system of controls also is based in part upon certain assumptions about 
the likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all 
potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error or 
fraud may occur and not be detected. In addition, projections of any evaluation of effectiveness to future periods are subject to the 
risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or 
procedures may deteriorate. 
 

23 
 
The Company’s Chief Financial Officer and Chief Executive Officer evaluated the effectiveness of the Company’s internal controls 
over financial reporting as at July 31, 2021 and identified a material weakness resulting from the Company’s limited accounting 
resources and technical expertise to ensure complex and non-routine transactions are addressed during the financial statement 
close process. As a result, the control deficiency creates a reasonable possibility that a material misstatement of interim and 
annual financial statements may not be prevented or detected on a timely basis. As no material change to the Company’s ICFR 
has occurred during the year ended July 31, 2022, the Company’s Chief Financial Officer has concluded that the material 
weakness remains in effect as of the date of this MD&A. Management and the Board have been assessing the effectiveness of 
the Company’s internal controls in the interim period and have since retained the services of a new CEO, CFO and appointed 
three new Board members. 
 
Management believes, based on its knowledge, that (i) this MD&A does not contain any untrue statements of a material fact or 
omit to state a material fact necessary to make the statements not misleading, in light of the circumstances under which they were 
made, with respect to the period covered by this MD&A and, (ii) the annual financial statements and other financial information 
included in this MD&A, fairly present in all material respects the financial condition, results of operations and cash flows at, and 
for, the fiscal periods presented in this MD&A. 
 
Management is confident that the Company will be able to address the material weakness in ICFR in fiscal 2023.

receipts related to this financing with insiders subscribing for $270,000. The closing of the private placement is expected by 
November 1, 2022. 
 
RISKS AND UNCERTAINTIES 
 
The Company is subject to risks, events and uncertainties, or “risk factors”, associated with being a publicly traded company 
operating in the biotechnology industry, with research and development stage projects in pre-clinical discovery and clinical 
development and with no expectation of revenue or profits in the foreseeable future and, as such, is heavily dependant on raising 
sufficient capital on a timely basis in order to advance the Company’s drug development programs.  As a result of these risk 
factors, reported information and forward-looking information may not necessarily be indicative of future operating results or of 
future financial position, and actual results may vary from the forward-looking information or reported information.  The Company 
cannot predict all of the risk factors, nor can it assess the impact, if any, of such risk factors on the Company’s business or the 
extent to which any factor, or combination of factors, may cause future results or financial position to differ materially from either 
those reported or those projected in any forward-looking information.  Accordingly, reported financial information and forward-
looking information should not be relied upon as a prediction of future actual results.  Some of the risks and uncertainties affecting 
the Company, its business, operations and results which could cause actual results to differ materially from those reported or from 
forward-looking information include, either wholly or in part, those described elsewhere in this MD&A, as well as the following: 
 
Risks Related to the Company’s Business 
 
The Company does not have any source of operating income and is dependent solely on outside sources of financing 
 
The Company’s operations consist of research and development activities, which do not generate any revenue. 
Accordingly, the Company has no source of revenue, positive operating cash flow or operating earnings to subsidize its 
ongoing research and development and other operating activities and the ability of the Company to continue as a going 
concern is dependent upon the Company’s ability to rely on cash on hand, and on outside sources of financing to fund 
its ongoing research and development and other operating activities. Such sources of financing involve risks, including 
that the Company will not be able to raise such financing on terms satisfactory to the Company or at all, and that any 
additional equity and/or any convertible debt financing, if secured, would result in dilution to existing shareholders, and 
that such dilution may be significant. The Company may also seek additional funding from or through other sources, 
including technology licensing, co-development collaborations, mergers and acquisitions, joint ventures, and other 
strategic alliances, which, if obtained, may reduce the Company’s interest in its projects or products or result in significant 

24 
 
dilution to existing shareholders. The Company may also seek additional funding from government grants. There can be 
no assurance, however, that any alternative sources of funding will be available. The failure of the Company to obtain 
additional financing on a timely basis may result in the Company reducing, delaying or cancelling one or more of its 
planned research and development programs, including clinical trials, further reducing overhead, or monetizing non-core 
assets, any of which could impair the current and future value of the business or cause the Company to consider ceasing 
operations and undergoing liquidation.  
 
The Company has a history of losses and expects to continue to incur additional losses for the foreseeable future 
 
The Company’s primary focus continues to be on its research and development of drug product candidates. The research 
and development of drug product candidates require the expenditure of significant amounts of cash over a relatively long-
time period. The Company expects to continue to incur losses from continuing operations for the foreseeable future. The 
Company’s accumulated deficit as at July 31, 2022 is $195,117,000. There can be no assurance that the Company will 
record earnings in the future or that the drug product candidates under development by us will be approved for sale in 
Canada, the United States, or elsewhere. Furthermore, there can be no assurance that if such products are approved, 
they will be successfully commercialized, and the extent of our future losses and the timing of our profitability are highly 
uncertain. If we are unable to achieve profitability, we may be unable to continue our operations. 
 
The Company faces risks in connection with competition and technological change 
 
The biotechnology industry is subject to rapid and substantial technological change. Technological competition from 
pharmaceutical companies, biotechnology companies and university researchers is intense and is expected to continue 
to be intense. 
 
The rapid advancement of immunotherapies has and likely will continue to significantly change the treatment of cancer 
and may result in a reduction, which may be significant, in the potential patient population and/or treatment protocols 
available to chemotherapies and other treatments currently in development, such as the Company’s primary drug product 
candidate, L-DOS47. Developments in immunotherapies have resulted in the Company repositioning its L-DOS47 lead 
drug product candidate away from a front-line monotherapy protocol towards second and third-line combination therapies 
with existing chemotherapy drugs and possibly in combination with immunotherapies, resulting in additional expenditures 
and delays in previously anticipated development timelines for L-DOS47. Advancements in technology can impact the 
Company at any time and as such, any further repositioning, would likely result in additional expenses being incurred by 
the Company and in further delays in the anticipated development timeline for L-DOS47, or in the Company determining 
that its L-DOS47 drug product candidate is no longer viable. The Company is currently heavily dependent on the success 
of its lead drug product candidate L-DOS47, which is the only drug candidate currently in clinical development. 
 
The Company cell-based therapies initiative may face significant hurdles. The Company’s effort is mainly at research 
proof-of-concept stage. It is possible that the selected targets or choice of antibodies are not optimal. This can delay the 
initiation of formal preclinical and clinical development significantly. The Company has chosen to develop cell-based 
therapy for solid tumour. While there are many successful examples of cell-based therapy treatment in hematological 
malignancies, similar success in solid tumour is less certain. 
 
Many of the Company’s competitors have substantially greater financial, technical and human resources and significantly 
greater experience in conducting preclinical testing and human clinical trials of product candidates, scaling up 
manufacturing operations and obtaining regulatory approvals of products. Accordingly, the Company’s varying 
competitors may succeed in obtaining regulatory approval for products more rapidly. The Company’s ability to compete 
successfully will largely depend on: 
 
 
the efficacy and safety profile of our product candidates relative to marketed products and other product candidates 
in development; 
 
our ability to develop and maintain a competitive position in the product categories and technologies on which we 
focus; 
 
the time it takes for our product candidates to complete clinical development and receive marketing approval; 
 
our ability to obtain required regulatory approvals; 
 
our ability to commercialize any of our product candidates that receive regulatory approval; 
 
our ability to establish, maintain and protect intellectual property rights related to our product candidates; and 
 
acceptance of any of our product candidates that receive regulatory approval by physicians and other healthcare 
providers and payers. 
 
Competitors have developed and may develop technologies that could be the basis for products that challenge the 
differentiated nature and potential for best-in-class product development programs and discovery research capabilities of 
the DOS47 platform technology. Some of those products may have an entirely different approach or means of 
accomplishing the desired therapeutic effect than our product candidates and may be more effective or less costly than 
our product candidates. The success of our competitors and their products and technologies relative to our technological 
capabilities and competitiveness could have a material adverse effect on the future preclinical studies a nd clinical trials 
of our product candidates, including our ability to obtain the necessary regulatory approvals for the conduct of such clinical 

25 
 
trials. This may further negatively impact our ability to generate future product development programs with improved 
pharmacological properties. 
 
If we are not able to compete effectively against our current and future competitors, our business will not grow and our 
financial condition and operations will substantially suffer. 
 
The Company is heavily dependent on the success of a single drug product candidate 
 
The Company’s future success is dependent primarily on the regulatory approval and commercialization of a single drug 
product candidate, L-DOS47, which is the Company’s only drug candidate currently in clinical development. The 
Company does not have any products that have obtained regulatory approval. The Company is conducting early stage 
research and development initiatives and is currently in the process of developing L-DOS47, which will require further 
time-consuming and costly research and development. There can be no assurance that L-DOS47 or any other drug 
product candidate that the Company undertakes to develop will ever be successfully developed or commercialized. As a 
result, the Company’s near-term prospects, including its ability to finance its operations and generate revenue, are 
substantially dependent on its ability to obtain regulatory approval for, and, if approved, to successfully commercialize L-
DOS47 in a timely manner. 
 
The Company’s single lead drug product candidate, L-DOS47, may not be accepted by the market and may never 
generate revenue and the Company has limited sales, marketing and distribution experience 
 
Even with regulatory approval, the Company may not achieve market acceptance of its lead drug product candidate, L-
DOS47, which depends on a number of factors, including the establishment and demonstration in the medical community 
of the clinical utility of the Company’s products, and their potential advantage over alternative treatment methods. There 
is also the risk that the actual market size or opportunity for any drug candidate developed by the Company is uncertain. 
Failure to gain market acceptance of the Company’s products or an incorrect estimate in the nature and size of the 
markets for the Company’s products could have a material adverse effect on the Company. 
 
The Company has limited sales, marketing and distribution experience, and there is no assurance that the Company will 
be able to establish adequate sales, marketing, and distribution capabilities or make arrangements with any collaborators, 
strategic partners, licensees, or others to perform such activities, or that such efforts will be successful. The Company’s 
objective for L-DOS47 is to enter into strategic alliances with appropriate pharmaceutical partners. There can be no 
assurance that any such strategic alliance will be maintained or achieved, or if achieved, that it will result in revenue to 
the Company. 
 
The timing of the Company’s internal goals and projected timelines may not be met 
 
The Company sets internal goals for and makes public statements regarding its expected timing of meeting the objectives 
material to its success, including the commencement, duration and completion of clinical trials and anticipated regulatory 
approvals. The actual timing of these forward-looking events can vary dramatically due to a number of factors, including, 
without limitation, delays in scaling-up of drug product candidates, delays or failures in clinical trials, additional data 
requirements from the regulators, the Company failing to obtain required financing, and other risks referred to herein. 
Without limiting the generality of the foregoing, it is possible that required regulatory approvals may be delayed or denied, 
including those related to undertaking or continuing clinical trials, manufacturing of drug products, and marketing such 
products. 
 
A failure to obtain necessary financing or a change in the schedule of a clinical trial (which may occur for many reasons, 
including due to factors beyond the Company’s reasonable control, such as scheduling conflicts, the occurrence of 
serious adverse events, interruption of supplies of study drugs, withdrawals of regulatory approvals, or slow patient 
recruitment) could delay the commencement or completion of the clinical trial, or result in its suspension or early 
termination, which could have a material adverse effect on the Company. 
 
We will have significant additional future capital needs in 2023 and beyond and there may be uncertainties as to our 
ability to raise additional funding in the future to meet these needs 
 
We will require significant additional capital resources to expand our business, in particular the further development of our product 
candidate, L-DOS47. Advancing our product candidate, marketing for our product, or acquisition and development of any new 

26 
 
products or product candidates will require considerable resources and additional access to capital markets. In addition, our future 
cash requirements may vary materially from those now expected. For example, our future capital requirements may increase if: 
 
 
we experience unexpected or increased costs relating to preparing, filing, prosecuting, maintaining, defending and 
enforcing patent claims, or other lawsuits, brought by either us or our competition; 
 
we experience scientific progress sooner than expected in our discovery, research and development projects, if we 
expand the magnitude and scope of these activities, or if we modify our focus as a result of our discoveries; 
 
we are required to perform additional pre-clinical studies and clinical trials; or 
 
we elect to develop, acquire or license new technologies, products or businesses. 
 
The Company could potentially seek additional funding through corporate collaborations and licensing arrangements or 
through public or private equity or debt financing. However, if capital market conditions in general, or with respect to life 
sciences companies such as ours, are unfavorable, our ability to obtain significant additional funding on acceptable terms, 
if at all, will be negatively affected. Additional financing that we may pursue may involve the sale of Common Shares 
which could result in significant dilution to our shareholders. If sufficient capital is not available, we may be required to 
delay our research and development projects, which could harm our business, financial condition, prospects or results 
of operations. 
 
The Company may not obtain adequate protection for its products through its intellectual property 
 
The Company’s success depends, in large part, on the Company’s ability to protect its competitive position through 
patents, trade secrets, trademarks, and other intellectual property rights. The Company’s success, competitive position 
and future revenues with respect to its product candidates will depend, in part, on the Company’s ability to protect its 
intellectual property. The Company will be able to protect its proprietary rights from unauthorized use by third parties only 
to the extent that its proprietary rights are covered by valid and enforceable patents or are effectively maintained as trade 
secrets. The Company seeks intellectual property protection in various jurisdictions around the world and owns patents 
and patent applications relating to biological products and technologies in the United States, Canada, Europe and other 
jurisdictions. The scope and duration of the Company’s intellectual property rights vary from country to country depending 
on the nature and extent of the Company’s intellectual property filings, the applicable statutory provisions governing the 
intellectual property, and the nature and extent of the Company’s legal rights. The Company’s failure to do so may 
adversely affect the Company’s business and competitive position.  
 
The patent positions of pharmaceutical and biopharmaceutical firms, including the Company’s, are uncertain and involve 
complex questions of law and fact for which certain important legal issues remain unresolved. The patents issued or to 
be issued to the Company may not provide the Company with any competitive advantage. The Company may not be able 
to protect its intellectual property rights throughout the world. The Company’s patents may be challenged by third parties 
in patent litigation. In addition, it is possible that third parties with biological products that are very similar to the Company’s 
may circumvent the Company’s patents by means of alternate designs or processes. The Company may have to rely on 
method of use patent protection for its biological products in development and any resulting biological products, which 
may not confer the same level of protection as protection of the Company’s biological products per se. The Company 
may be required to disclaim part of the term of certain patents in the United States. There may be prior art of which the 
Company is not aware that may affect the validity or enforceability of a patent claim. There also may be prior art of which 
the Company is aware, but which the Company does not believe affects the validity or enforceability of a claim, which 
may, nonetheless ultimately be found to affect the validity or enforceability of a claim. No assurance can be given that the 
Company’s patents would, if challenged, be held by a court to be valid or enforceable or that a competitor’s technology 
or drug would be found by a court to infringe the Company’s patents. 
 
Patent terms may be inadequate to protect the Company’s competitive position on its product candidates for an adequate 
amount of time. Patents have a limited lifespan, in most jurisdictions inclusive of the United States, if all maintenance fees 
are timely paid, the term of protection is a period of 20 years from the filing date of the application. Patent term extensions 
of up to 5 years may be available in certain countries for patents pertaining to new medicinal ingredients or new 
combinations of medicinal ingredients for human or veterinary use based upon the delay in regulatory review. Even if 
patents covering the Company’s product candidates are obtained, once the patent life and any patent term extension 
have expired, the Company may be open to competition from competitive products, including generics or biosimilars. 
Given the amount of time required for the development, testing and regulatory review of new product candidates, patents 
protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, the 
Company’s owned and licensed patent portfolio may not provide the Company with sufficient rights to exclude others from 
commercializing products similar or identical to the Company’s. 
 
Patent applications relating to or affecting the Company’s business may have been filed by a number of pharmaceutical 
and biopharmaceutical companies and academic institutions. The technologies in these applications or patents may cover 
the Company’s technologies, and such conflict could create freedom to operate issues. The Company’s granted patents 
could be challenged, invalidated or found unenforceable in interference and derivation proceedings, and post grant 
proceedings including re-examination, Inter Parte Review and Post-Grant Review, in the United States. The Company’s 
granted patents could also be challenged and revoked in opposition proceedings in certain countries outside of the United 
States such as in Europe. In addition to patents, the Company relies on trade secrets and proprietary know-how to protect 

27 
 
its intellectual property. The Company generally requires employees, consultants, outside scientific collaborators, and 
sponsored researchers and other advisors to enter into confidentiality agreements. These agreements provide that all 
confidential information developed or made known to the individual during the course of the individual’s relationship with 
the Company is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of 
employees, the agreements provide that all of the technology that is conceived by the individual during the course of 
employment is the Company’s exclusive property. These agreements may not provide meaningful protection or adequate 
remedies in the event of unauthorized use or disclosure of proprietary information. In addition, it is possible that third 
parties could independently develop proprietary information and techniques substantially similar to the Company’s or 
otherwise gain access to the Company’s trade secrets. 
 
The Company may obtain the right to use certain technology under license agreements with third parties. The Company’s 
failure to comply with the requirements of material license agreements could result in the termination of such agreements, 
which could cause the Company to terminate the related development program and cause a complete loss of investment 
in that program. As a result of the foregoing factors, the Company may not be able to rely on its intellectual property to 
protect the Company’s products in the marketplace. 
 
Patent litigation is costly and time consuming and may subject the Company to liabilities 
 
The Company’s involvement in any patent litigation, opposition, or other administrative proceedings will likely cause the 
Company to incur substantial expenses, and the efforts of technical and management personnel will be significantly 
diverted. In addition, the Company may not have the financial means defend its patents and in the event it does, an 
adverse determination in litigation could subject the Company to significant liabilities, including, but not limited to, 
monetary damages. 
 
Security breaches and other disruptions could compromise the Company’s information and expose the Company to 
liability, which would cause the Company’s business and reputation to suffer 
 
In the ordinary course of our business, the Company collects and stores sensitive data, including intellectual property, 
proprietary business information and that of our suppliers and business partners, and personally identifiable information 
of our collaborators and employees, on our networks and on shared cloud services. The secure processing, maintenance 
and transmission of this information is critical to our operations. Despite our security measures, our information 
technology and infrastructure may be exposed to malware, cyberattacks, attacks by hackers or breached due to 
employee error, malfeasance, or other disruptions. Any such breach could compromise our networks and the information 
stored there could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information 
could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, disrupt our 
operations and damage our reputation, which could adversely affect our business and competitive position. 
 
Further, some of our partners may store personal or confidential information that we share with them. If these third parties 
fail to implement adequate data-security practices or fail to comply with our terms and policies, sensitive data may be 
improperly accessed, acquired, or disclosed. And even if these third parties take all these steps, their networks and 
information technology systems may still suffer a security breach, which could compromise our data. 
 
The Company may infringe the intellectual property rights of others 
 
The Company’s commercial success depends significantly on the Company’s ability to operate without infringing on the 
patents and other intellectual property rights of third parties. There could be issued patents of which the Company is not 
initially aware that the Company’s products infringe or patents that the Company believes it does not infringe, but that 
the Company may ultimately be found to infringe. Patent applications are maintained in secrecy from the time of filing 
until publication. The publication of discoveries in the scientific or patent literature frequently occurs later than the date 
on which the underlying discoveries were made and patent applications were filed. There may be currently pending 
patent applications of which the Company is unaware that may later result in issued patents that the Company’s products 
infringe. 
 
The biopharmaceutical industry has produced a proliferation of patents in jurisdictions around the world. The coverage 
of patents is subject to interpretation by the courts of a particular jurisdiction, and the interpretation is not always uniform. 
The Company believes that the sale or use of its primary biological product candidate, L-DOS47 would not infringe any 
valid claim of patents, although there can be no assurances of this. In the event of an infringement or violation of another 
party’s patent, the Company may not be able to enter into licensing arrangements or make other arrangements at a 
reasonable cost. Any inability to secure licenses or alternative technology could result in delays in the introduction of 
drugs or lead to prohibition of the manufacture or sale of drugs by the Company. 
 
Third parties may initiate legal proceedings alleging that the Company is infringing their intellectual property rights, the 
outcome of which would be uncertain and could harm the Company’s business 
 
Third parties may assert patent or other intellectual property infringement claims against the Company or its other 
licensors arising from the manufacture, use, or sale of the Company’s current or future product candidates. An 

28 
 
unfavorable outcome could result in loss of patent rights and require the Company to cease using the related technology 
or to attempt to license rights to it from the prevailing party. The Company’s business could be harmed if the prevailing 
party does not offer us a license on commercially reasonable terms. The Company may not have the financial means 
and wherewithal to defend against third party claims and in the event it does, defense of litigation proceedings may fail 
and, even if successful, may result in substantial costs and distract the Company’s management and other employees. 
In the event of a successful claim of infringement against the Company, the Company may have to pay substantial 
damages, including treble damages and legal fees for willful infringement, pay royalties, redesign its infringing products 
or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary 
expenditure. 
 
The Company may become involved in lawsuits or other proceedings to protect or enforce the Company’s patents or 
other intellectual property, which could be expensive, time consuming and unsuccessful 
 
Competitors may infringe the Company’s patents or other intellectual property. The Company may not have the financial 
means and wherewithal to defend its patents or other intellectual properties and in the event the Company was to initiate 
legal proceedings against a third party to enforce a patent covering the Company’s product candidates, the defendant 
could counterclaim that the patent covering the Company’s product candidate is invalid and/or unenforceable. In patent 
litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace. 
Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack 
of novelty, obviousness, written description, enablement, or clarity. Grounds for an unenforceability assertion could be 
an allegation that someone connected with prosecution of the patent withheld relevant information from the United States 
Patent and Trademark Office, or “USPTO”, or made a misleading statement, during prosecution. The outcome following 
legal assertions of invalidity and unenforceability is unpredictable. The validity of the Company’s current or future patents 
or patent applications or those of the Company’s licensors may also be challenged in interference or derivation 
proceedings, opposition, post grant review, inter partes review, or other similar enforcement and revocation proceedings, 
provoked by third parties or brought by the Company. The Company’s patents could be found invalid, unenforceable, or 
their scope significantly reduced. 
 
The Company may be subject to claims challenging the inventorship of the Company’s patents and other intellectual 
property 
 
The Company or its licensors may be subject to claims that former employees, collaborators or other third parties have 
an interest in the Company’s owned or in-licensed patents, trade secrets, or other intellectual property as an inventor or 
co-inventor. For example, the Company or its licensors may have inventorship disputes arise from conflicting obligations 
of employees, collaborators, consultants or others who are involved in developing the Company’s product candidates. 
Litigation may be necessary to defend against these and other claims challenging inventorship of the Company’s or its 
licensors’ ownership of the Company’s owned or in-licensed patents, trade secrets or other intellectual property. The 
Company may not have the financial means to defend such claims and in the event the Company or its licensors fail in 
defending any such claims, in addition to paying monetary damages, the Company may lose valuable intellectual property 
rights, such as exclusive ownership of, or right to use, intellectual property that is important to the Company’s product 
candidates. Even if the Company is successful in defending against such claims, litigation could result in substantial costs 
and be a distraction to management and other employees. Any of the foregoing could have a material adverse effect on 
the Company’s business, financial condition, results of operations and prospects. 
 
The Company may be subject to claims that its employees, collaborators, consultants or independent contractors have 
wrongfully used or disclosed confidential information of third parties or that the Company’s employees have wrongfully 
used or disclosed alleged trade secrets of their former employers 
 
As is common in the biotechnology and pharmaceutical industry, the Company employs individuals who were previously 
employed at universities or other biotechnology or pharmaceutical companies, including the Company’s competitors or 
potential competitors. Although the Company tries to ensure that its employees, collaborators, consultants and 
independent contractors do not use the proprietary information or know-how of others in their work for the Company, the 
Company may be subject to claims that the Company or its employees, consultants or independent contractors have 
inadvertently or otherwise used or disclosed intellectual property, including trade secrets or other proprietary information, 
of any of the Company’s employees’ former employers or other third parties. Litigation may be necessary to defend 
against these claims. The Company may not have the financial means to defend such claims and in the event the 
Company fails in defending any such claims, in addition to paying monetary damages, the Company may lose valuable 
intellectual property rights or personnel, which could adversely impact the Company’s business. Even if the Company is 

29 
 
successful in defending against such claims, litigation could result in substantial costs and be a distraction to management 
and other employees. 
 
Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, 
fee payment and other requirements imposed by governmental patent agencies, and the Company’s patent protection 
could be reduced or eliminated for non-compliance with these requirements 
 
Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or 
applications will be due to be paid to the USPTO and various governmental patent agencies outside of the United States 
in several stages over the lifetime of the patents and/or applications. The Company has systems in place to remind the 
Company to pay these fees, and the Company employs an outside firm and relies on its outside counsel to pay these 
fees due to non-U.S. patent agencies. The USPTO and various non-U.S. governmental patent agencies require 
compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent 
application process. The Company employs reputable law firms and other professionals to help the Company comply, 
and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with 
the applicable rules. However, there are situations in which non-compliance can result in abandonment or lapse of the 
patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an 
event, the Company’s competitors might be able to enter the market and this circumstance would have a material adverse 
effect on the Company’s business. 
 
The Company faces research and development risks, including the need to prove the Company’s drug candidates are 
safe and effective in clinical trials 
 
The Company’s drug candidates are complex compounds and the Company faces difficult challenges in connection with 
the manufacture of clinical batches of each of them, which could further delay or otherwise negatively affect the 
Company’s planned clinical trials, or required regulatory approvals. 
 
There is also the risk that the Company could obtain negative findings or factors that may become apparent during the 
course of research or development. The results from preclinical and clinical trials may not be predictive of results obtained 
in any ongoing or future clinical trials. A number of companies in the biotechnology and pharmaceutical industry have 
suffered significant setbacks in advanced clinical trials, even after achieving promising results in earlier trials and pre-
clinical trials. 
 
The timing and success of the Company’s clinical trials also depend on a number of other factors, including, but not 
limited to: (a) obtaining additional financing, which is not assured; (b) sufficient patient enrolment, which may be affected 
by the incidence of the disease studied, the size of the patient population, the nature of the protocol, the proximity of 
patients to clinical sites, the eligibility criteria for a patient to participate in the study and the rate of patient drop-out; (c) 
regulatory agency policies regarding requirements for approval of a drug, including granting permission to undertake 
proposed human testing; (d) the Company’s capacity to produce sufficient quantities and qualities of clinical trial materials 
to meet the trial schedule; (e) performance by third parties, on whom the Company relies to carry out its clinical trials; 
and (f) the approval of protocols and/or protocol amendments. 
 
Clinical trials are complex, expensive and uncertain, and have a high risk of failure, which can occur at any stage. Data 
obtained from pre-clinical and clinical trials may be interpreted in different ways, or be incorrectly reported, which could 
delay or prevent further development of the drug candidate studied. Failure to complete clinical trials successfully and to 
obtain successful results on a timely basis could have a material adverse effect on the Company. 
 
Even if the Company’s drug candidates successfully complete the clinical trials and receive the regulatory approval 
necessary to market the drug candidates to the public, there is also the risk of unknown side effects, which may not 
appear until the drug candidates are on the market and may result in delay or denial of regulatory approval or withdrawal 
of previous approvals, product recalls or other adverse events, which could materially adversely affect the Company. 
 
While the Company continues to explore opportunities to expand its drug product pipeline with new DOS47-based 
therapeutics pending the identification of further tumour targeting agents, there can be no assurance that any such 
tumour targeting agents will be identified or that any new DOS47-based therapeutics will be developed. 
 
The regulatory approval processes of the FDA and comparable foreign authorities are lengthy, time consuming, 
expensive and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product 
candidates, our business will be substantially harmed 
 
The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable but typically takes 
many years following the commencement of clinical trials and depends upon numerous factors, including the substantial 
discretion of the regulatory authorities. The results of preclinical studies and early clinical trials of our product candidates 
may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may 
fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical 
trials. It is not uncommon for companies in the biopharmaceutical industry to suffer significant setbacks in advanced 

30 
 
clinical trials due to nonclinical findings made while clinical studies were underway and safety or efficacy observations 
made in clinical studies, including previously unreported adverse events. Our future clinical trial results may not be 
successful, and notwithstanding any potential promising results in earlier studies, we cannot be certain that we will not 
face similar setbacks. The historical failure rate for product candidates in our industry is high. In addition, approval 
policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course 
of a product candidate’s clinical development and may vary among jurisdictions. We have not obtained regulatory 
approval for any product candidate and it is possible that none of our existing product candidates or any product 
candidates we may seek to develop in the future will ever obtain regulatory approval. 
 
Our product candidates could fail to receive regulatory approval for many reasons, including the following: 
 
 
the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical 
trials; 
 
we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that a 
product candidate is safe and effective for its proposed indication; 
 
the results of clinical trials may not meet the level of statistical significance required by the FDA or comparable 
foreign regulatory authorities for approval; 
 
the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical 
studies or clinical trials; 
 
the data collected from clinical trials of our product candidates may not be sufficient to support the submission of an 
New Drug Application, or NDA, or other submission or to obtain regulatory approval in the United States or 
elsewhere;  
 
the FDA or comparable foreign regulatory authorities may fail to approve the manufacturing processes or facilities 
of third-party manufacturers with which we contract for clinical and commercial supplies; and 
 
the approval policies or regulations of the FDA or comparable foreign regulatory authorities may significantly change 
in a manner rendering our clinical data insufficient for approval. 
 
We may not have the necessary capabilities, including adequate staffing, to successfully manage the execution and 
completion of any future clinical trials we initiate in a way that leads to our obtaining marketing approval for our product 
candidates in a timely manner, or at all. This lengthy approval process as well as the unpredictability of future clinical trial 
results may result in our failing to obtain regulatory approval to market our product candidates, which would significantly 
harm our business, results of operations and prospects. 
 
In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for 
fewer or more limited indications than we request, may not approve the price we intend to charge for our products, may 
grant approval contingent on the performance of costly post-marketing clinical trials, may approve a product candidate 
with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that 
product candidate or may restrict its distribution. Any of the foregoing scenarios could materially harm the commercial 
prospects for our product candidates. 
 
We have not previously submitted an NDA to the FDA or similar drug approval filings to comparable foreign authorities, 
for any product candidate, and we cannot be certain that any of our product candidates will be successful in clinical trials 
or receive regulatory approval. Further, our product candidates may not receive regulatory approval even if they are 
successful in clinical trials. If we do not receive regulatory approvals for our product candidates, we may not be able to 
continue our operations. Even if we successfully obtain regulatory approvals to market one or more of our product 
candidates, our revenues will be dependent, in part, upon the size of the markets in the territories for which we gain 
regulatory approval and have commercial rights. If the markets for patients that we are targeting for our product 
candidates are not as significant as we estimate, we may not generate significant revenues from sales of such products, 
if approved. 
 
We plan to seek regulatory approval to commercialize our product candidates both in the United States and the European 
Union and in additional foreign countries. While the scope of regulatory approval is similar in other countries, to obtain 
separate regulatory approval in many other countries we must comply with numerous and varying regulatory 
requirements of such countries regarding safety and efficacy and governing, among other things, clinical trials and 
commercial sales, pricing and distribution of our product candidates, and we cannot predict success in these jurisdictions. 
 
Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their 
regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences 
following marketing approval, if any 
 
Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or 
halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or 
other comparable foreign authorities. The clinical evaluation of our product candidates in patients is still in the early stages 
and it is possible that there may be side effects associated with their use. Results of our trials could reveal a high and 
unacceptable severity and prevalence of these or other side effects. In such an event, we, the FDA, the IRBs at the 
institutions in which our studies are conducted, or the DSMB could suspend or terminate our clinical trials or the FDA or 

31 
 
comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates 
for any or all targeted indications. Treatment-related side effects could also affect patient recruitment or the ability of 
enrolled patients to complete the clinical trial or result in potential product liability claims. In addition, these side effects 
may not be appropriately recognized or managed by the treating medical staff. We expect to have to train medical 
personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any 
commercialization of any of our product candidates. Inadequate training in recognizing or managing the potential side 
effects of our product candidates could result in patient injury or death. Any of these occurrences may harm our business, 
financial condition and prospects significantly.  
 
Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify 
undesirable side effects caused by such products, a number of potentially significant negative consequences could result, 
including: 
 
 
regulatory authorities may withdraw approvals of such products; 
 
we may be required to recall a product or change the way such a product is administered to patients; 
 
additional restrictions may be imposed on the marketing or distribution of the particular product or the manufacturing 
processes for the product or any component thereof; 
 
regulatory authorities may require additional warnings on the label, such as a “black box” warning or contraindication; 
 
we may be required to implement Risk Evaluation and Mitigation Strategies, or REMS, or create a medication guide 
outlining the risks of such side effects for distribution to patients; 
 
we could be sued and held liable for harm caused to patients; 
 
our product may become less competitive; and 
 
our reputation may Any of these events could prevent us from achieving or maintaining market acceptance of the 
particular product candidate or for particular indications of a product candidate, if approved, and could significantly 
harm our business, results of operations and prospects. 
 
Difficulty in enrolling patients in the Company’s clinical trials, could result in delays or cancellation of clinical trials 
 
As the Company’s product candidates advance from preclinical testing to clinical testing, and then through progressively 
larger and more complex clinical trials, the Company will need to enroll an increasing number of patients that meet various 
eligibility criteria. There is significant competition for recruiting cancer patients in clinical trials, and the Company may be 
unable to enroll the patients it needs to complete clinical trials on a timely basis or at all. The factors that affect the 
Company’s ability to enroll patients is largely uncontrollable and include, but are not limited to, the following: 
 
 
size and nature of the patient population; 
 
eligibility and exclusion criteria for the trial; 
 
design of the study protocol; 
 
competition with other companies for clinical sites or patients; 
 
the perceived risks and benefits of the product candidate under study; 
 
the patient referral practices of physicians; and 
 
the number, availability, location and accessibility of clinical trial sites. 
 
The Company is dependent on a number of third parties and the failure or delay in the performance of one of these third 
parties’ obligations may adversely affect the Company 
 
The Company is dependent on third parties to varying degrees in virtually all aspects of its business, including without 
limitation, on contract research organizations, contract manufacturing organizations, clinical trial consultants, raw material 
suppliers, collaborative research consultants, regulatory affairs advisers, medical and scientific advisors, clinical trial 
investigators, business service providers and other third parties. Critical supplies may not be available from third parties 
on acceptable terms, or at all, including GMP grade materials. Service providers may not perform, or continue to perform, 
as needed, or be available to provide the required services on acceptable terms or at all. Any lack of or interruption in 
supplies of raw materials or services, or any change in supply or service providers or any inability to secure new supply 
or service providers, would have an adverse impact on the development and commercialization of the Company’s 
products. For example, the Company has previously experienced delays in the manufacturing of both engineering and 
clinical batches of L-DOS47, which have in turn caused delays in the progression of its development program, and there 
may be further delays. The Company relies on a third party for its supply of urease and if the contract with the third-party 
urease supplier is terminated early, the Company will have to find a new supplier of urease, as well as a new manufacturer 
of bulk drug product for future clinical testing programs. There can be no assurance that a new supplier or manufacturer 
can be contracted in a timely manner or at all, and this could negatively impact the Company’s development plans for L-
DOS47. 
 
With respect to L-DOS47, the Company is currently dependent on, in addition to third party suppliers, manufacturers and 
consultants, the NRC and its license to the Company of a lung cancer antibody in order to develop and commercialize L-
DOS47. Early termination of the license with NRC would have a material adverse effect on the further development of L-
DOS47 and may require the cessation of such development, which would have a material adverse effect on the Company. 
 

32 
 
Given the Company`s lack of financing, expertise, infrastructure and other resources to support a new drug product from 
clinical development to marketing, the Company also requires strategic partner support to develop and commercialize its 
drug candidates. There can be no assurance that such strategic partner support will be obtained upon acceptable terms 
or at all. 
 
The Company relies heavily on contract manufacturers for the production of product required for its clinical trials, product 
formulation work, scaling-up experiments and commercial production. The Company may not be able to obtain new, or 
keep its current, contract manufacturers to provide these services. Even if the Company does, contract manufacturers 
may not be reliable in meeting its requirements for cost, quality, quantity or schedule, or the requirements of any 
regulatory agencies. The Company may not be able to manufacture products in quantities or qualities that would enable 
the Company to meet its business objectives, and failure to do so would materially adversely affect the Company’s 
business. 
 
If the Company can successfully develop markets for its products, the Company would have to arrange for their scaled-
up manufacture. There can be no assurance that the Company will, on a timely basis, be able to make the transition from 
manufacturing clinical trial quantities to commercial production quantities successfully or be able to arrange for scaled-
up commercial contract manufacturing. Any potential difficulties experienced by the Company in manufacturing scale-up, 
including recalls or safety alerts, could have a material adverse effect on the Company’s business, financial condition, 
and results of operations. 
 
The Company relies significantly on licensed intellectual property. If the Company were to lose its rights to licensed 
intellectual property, the Company would not be able to continue developing or commercializing L-DOS47. If the 
Company breaches the agreement with NRC under which it licenses the use, development and commercialization rights 
to a lung cancer antibody in order to develop and commercialize L-DOS47 or any other future product candidate or 
technology from third parties or if certain insolvency events were to occur, the Company could lose license rights that 
are critical to its business 
 
The Company has an exclusive worldwide license to a lung cancer antibody necessary to develop and commercialize L-
DOS47 pursuant to a license agreement with NRC that is critical to the Company’s business, which is subject to 
termination for breach of certain terms and, therefore, the Company’s rights may only be available for as long as the 
Company’s development and commercialization activities are sufficient to meet the terms of the license. In addition, the 
Company may need to enter into additional license agreements in the future. The Company’s existing license agreements 
impose, and any future license agreements may impose on the Company, various developments, regulatory and/or 
commercial diligence obligations, payment of milestones and/or royalties and other obligations. If the Company fails to 
comply with its obligations under these agreements, or the Company is subject to a bankruptcy, the licensor may have 
the right to terminate the license, in which event the Company would not be able to market products covered by the 
license, which would have a material adverse effect on the Company’s business, financial condition, results of operations 
and prospects. Moreover, the Company’s current or future licenses may provide for a reversion to the licensor of the 
Company’s rights in regulatory filings or other intellectual property or data that the Company regards as its own in the 
event the license terminates under certain circumstances, such as due to breach. 
 
Licensing of intellectual property is of critical importance to the Company’s business and involves complex legal, business 
and scientific issues. Disputes may arise between us and the Company’s licensors regarding intellectual property subject 
to a license agreement, including with respect to: 
 
 
the scope of rights granted under the license agreement and other interpretation-related issues; 
 
the rights of the Company’s licensors under the license agreements; and 
 
the Company’s diligence obligations with respect to the use of the licensed technology in relation to the Company’s 
development and commercialization of L-DOS47 and any future product candidates, and what activities satisfy those 
diligence obligations. 
 
Any disputes with the Company’s licensors over intellectual property that the Company has licensed from them may 
prevent or impair the Company’s ability to maintain its current licensing arrangements on acceptable terms. Termination 
or expiry of the Company’s license agreements could result in the loss of significant rights and could materially harm the 
Company’s ability to further develop and commercialize L-DOS47 or other future product candidates. 
 
In addition, the agreements under which the Company currently licenses intellectual property or technology from third 
parties are complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The 
resolution of any contract interpretation disagreement that may arise could narrow what the Company believes to be the 
scope of its rights to the relevant intellectual property or technology, or increase what the Company believes to be its 
financial or other obligations under the relevant agreement, either of which could have a material adverse effect on the 
Company’s business, financial condition, results of operations, and prospects. Moreover, if disputes over intellectual 
property that the Company has licensed prevent or impair the Company’s ability to maintain its current licensing 
arrangements on commercially acceptable terms, the Company may be unable to successfully develop and 

33 
 
commercialize the affected product candidates, which could have a material adverse effect on the Company’s business, 
financial conditions, results from operations and prospects. 
 
The marketability of the Company’s products may be affected by delays and the inability to obtain necessary approvals, 
and following any market approval, the Company’s products will be subject to ongoing regulatory review and 
requirements which may continue to affect their marketability, including but not limited to regulatory review of drug 
pricing, healthcare reforms or the payment and reimbursement policies for drugs by the various insurers and other 
payors in the industry 
 
The research, development, manufacture and marketing of pharmaceutical products are subject to regulation by the 
FDA, and comparable regulatory authorities in other countries. These agencies and others regulate the testing, 
manufacture, safety and promotion of the Company’s products. The Company must receive applicable regulatory 
approval of a product candidate before it can be commercialized in any particular jurisdiction. Approval by a regulatory 
authority of one country does not ensure the approval by regulatory authorities of other countries. Changes in regulatory 
approval policies or regulations during the development period may cause delays in the approval or rejection of an 
application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any 
application or may decide that our data are insufficient for approval, or require additional preclinical, clinical or other trials 
and place the Company’s IND submissions on hold for an indeterminate amount of time. The development and regulatory 
approval process in each jurisdiction takes many years, requires the expenditure of substantial resources, is uncertain 
and subject to delays, and can adversely affect the successful development and commercialization of our drug 
candidates. 
 
Even if the Company obtains marketing approval in a particular jurisdiction, there may be limits on the approval and the 
Company’s products likely will be subject to ongoing regulatory review and regulatory requirements in that jurisdiction. 
Pharmaceutical companies are subject to various government regulations, including without limitation, requirements 
regarding occupational safety, laboratory practices, environmental protection and hazardous substance control, and may 
be subject to other present and future regulations. 
 
The availability of reimbursement by governmental and other third-party payors, such as private insurance plans, will 
affect the market for any pharmaceutical product, and such payors tend to continually attempt to contain or reduce the 
costs of healthcare. Significant uncertainty exists with respect to the reimbursement status of newly approved healthcare 
products. 
 
We are substantially dependent on third parties for the manufacture of our clinical supplies of our product candidates, 
and we intend to rely on third parties to produce commercial supplies of any approved product candidate. Therefore, our 
development of our products could be stopped or delayed, and our commercialization of any future product could be 
stopped or delayed or made less profitable if third party manufacturers fail to obtain approval of the FDA or comparable 
regulatory authorities or fail to provide us with drug product in sufficient quantities or at acceptable prices 
 
The manufacture of biotechnology and pharmaceutical products is complex and requires significant expertise, capital 
investment, process controls and know-how. Common difficulties in biotechnology and pharmaceutical manufacturing 
may include: sourcing and producing raw materials, transferring technology from chemistry and development activities 
to production activities, validating initial production designs, scaling manufacturing techniques, improving costs and 
yields, establishing and maintaining quality controls and stability requirements, batch lot expiries, eliminating 
contaminations and operator errors, and maintaining compliance with regulatory requirements. We do not currently have 
nor do we plan to acquire the infrastructure or capability internally in accordance with cGMP prescribed by the FDA or to 
produce an adequate supply of compounds to meet future requirements for clinical trials and commercialization of our 
products. Drug manufacturing facilities are subject to inspection before the FDA will issue an approval to market a new 
drug product, and all of the manufacturers that we intend to use must adhere to the cGMP regulations prescribed by the 
FDA. 
 
We expect therefore to rely on third-party manufacturers for clinical supplies of our product candidates that we may 
develop. These third-party manufacturers will be required to comply with current good manufacturing practices, or GMPs, 
and other applicable laws and regulations. We will have no control over the ability of these third parties to comply with 
these requirements, or to maintain adequate quality control, quality assurance and qualified personnel. If the FDA or any 
other applicable regulatory authorities do not approve the facilities of these third parties for the manufacture of our other 
product candidates or any products that we may successfully develop, or if it withdraws any such approval, or if our 
suppliers or contract manufacturers decide they no longer want to supply or manufacture for us, we may need to find 
alternative manufacturing facilities, in which case we might not be able to identify manufacturers for clinical or commercial 
supply on acceptable terms, or at all. Any of these factors would significantly impact our ability to develop, obtain 
regulatory approval for or market our product candidates and adversely affect our business. 
 
We and/or our third-party manufacturers may be adversely affected by developments outside of our control, and these 
developments may delay or prevent further manufacturing of our products. Adverse developments may include labor 
disputes, resource constraints, shipment delays, inventory shortages, lot failures, unexpected sources of contamination, 
lawsuits related to our manufacturing techniques, equipment used during manufacturing, or composition of matter, 

34 
 
unstable political environments, acts of terrorism, war, natural disasters, and other natural and man-made disasters. If 
we or our third-party manufacturers were to encounter any of the above difficulties, or otherwise fail to comply with 
contractual obligations, our ability to provide any product for clinical trial or commercial purposes would be jeopardized. 
This may increase the costs associated with completing our clinical trials and commercial production. Further, production 
disruptions may cause us to terminate ongoing clinical trials and/or commence new clinical trials at additional expense. 
We may also have to take inventory write-offs and incur other charges and expenses for products that fail to meet 
specifications or pass safety inspections. If production difficulties cannot be solved with acceptable costs, expenses, and 
timeframes, we may be forced to abandon our clinical development and commercialization plans, which could have a 
material adverse effect on our business, prospects, financial condition, and the value of our securities. 
  
We, or third-party manufacturers on whom we rely, may be unable to successfully scale-up manufacturing of our product 
candidates in sufficient quality and quantity, which would delay or prevent us from developing our product candidates 
and commercializing approved products, if any 
 
In order to conduct clinical trials of our product candidates and commercialize any approved product candidates, we, or 
our manufacturers, will need to manufacture them in large quantities. We, or our manufacturers, may be unable to 
successfully increase the manufacturing capacity for any of our product candidates in a timely or cost-effective manner, 
or at all. In addition, quality issues may arise during scale-up activities. If we, or any of our manufacturers, are unable to 
successfully scale up the manufacture of our product candidates in sufficient quality and quantity, the development, 
testing, and clinical trials of that product candidate may be delayed or infeasible, and regulatory approval or commercial 
launch of any resulting product may be delayed or not obtained, which could significantly harm our business. If we are 
unable to obtain or maintain third-party manufacturing for commercial supply of our product candidates, or to do so on 
commercially reasonable terms, we may not be able to develop and commercialize our product candidates successfully. 
 
Our failure to find third party collaborators to assist or share in the costs of product development could materially harm 
our business, financial condition and results of operations 
 
Our strategy for the development and commercialization of our proprietary product candidates may include the formation 
of collaborative arrangements with third parties. Existing and future collaborators have significant discretion in 
determining the efforts and resources they apply and may not perform their obligations as expected. Potential third party 
collaborators include biopharmaceutical, pharmaceutical and biotechnology companies, academic institutions and other 
entities. Third-party collaborators may assist us in: 
 
 
funding research, preclinical development, clinical trials and manufacturing; 
 
seeking and obtaining regulatory approvals; and 
 
successfully commercializing any future product candidates. 
 
If we are not able to establish further collaboration agreements, we may be required to undertake product development 
and commercialization at our own expense. Such an undertaking may limit the number of product candidates that we will 
be able to develop, significantly increase our capital requirements and place additional strain on our internal resources. 
Our failure to enter into additional collaborations could materially harm our business, financial condition and results of 
operations. 
 
In addition, our dependence on licensing, collaboration and other agreements with third parties may subject us to a 
number of risks. These agreements may not be on terms that prove favorable to us and may require us to relinquish 
certain rights in our product candidates. To the extent we agree to work exclusively with one collaborator in a given area, 
our opportunities to collaborate with other entities could be curtailed. Lengthy negotiations with potential new 
collaborators may lead to delays in the research, development or commercialization of product candidates. The decision 
by our collaborators to pursue alternative technologies or the failure of our collaborators to develop or commercialize 
successfully any product candidate to which they have obtained rights from us could materially harm our business, 
financial condition and results of operations. 
 
We rely on third parties to conduct our preclinical and clinical trials. If these third parties do not successfully perform 
their contractual legal and regulatory duties or meet expected deadlines, we may not be able to obtain regulatory 
approval for or commercialize our product candidates and our business could be substantially harmed 
 
We have relied upon and plan to continue to rely upon third-party medical institutions, clinical investigators, contract 
laboratories and other third party CROs to monitor and manage data for our ongoing preclinical and clinical programs. 
We rely on these parties for execution of our preclinical and clinical trials, and control only certain aspects of their 
activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the 
applicable protocol, legal, regulatory and scientific standards, and our reliance on the CROs does not relieve us of our 
regulatory responsibilities. We and our CROs are required to comply with cGCPs, which are regulations and guidelines 

35 
 
enforced by the FDA, the Competent Authorities of the Member States of the European Economic Area, or EEA, and 
comparable foreign regulatory authorities for all of our products in clinical development. 
 
Regulatory authorities enforce these cGCPs through periodic inspections of trial sponsors, principal investigators and 
trial sites. If we or any of our CROs fail to comply with applicable cGCPs, the clinical data generated in our clinical trials 
may be deemed unreliable and the FDA, the EMA or comparable foreign regulatory authorities may require us to perform 
additional clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a 
given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with cGCP 
regulations. In addition, our clinical trials must be conducted with product produced under current good manufacturing 
practices, or cGMP, regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which 
would delay the regulatory approval process. 
 
If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with 
alternative CROs or to do so on commercially reasonable terms. In addition, our CROs are not our employees, and 
except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote 
sufficient time and resources to our on-going clinical, nonclinical and preclinical programs. If CROs do not successfully 
carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality 
or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory 
requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to 
obtain regulatory approval for or successfully commercialize our product candidates. As a result, our results of operations 
and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to 
generate revenues could be delayed. 
 
Many of the third parties with whom we contract may also have relationships with other commercial entities, including 
our competitors, for whom they may also be conducting clinical trials or other drug development activities that could harm 
our competitive position. If the third parties conducting our GLP preclinical studies or our clinical trials do not perform 
their contractual duties or obligations, experience work stoppages, do not meet expected deadlines, terminate their 
agreements with us or need to be replaced, or if the quality or accuracy of the clinical data they obtain is compromised 
due to their failure to adhere to our clinical trial protocols or to GCPs, or for any other reason, we may need to enter into 
new arrangements with alternative third parties. Switching or adding additional CROs involves additional cost and 
requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. 
As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. 
Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter 
similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on 
our business, financial condition and prospects. 
 
The Company operates in an industry that is more susceptible than others to legal proceedings and, in particular, liability 
claims 
 
The Company operates in an industry that is more susceptible to legal proceedings than firms in other industries, due to 
the uncertainty involved in the development of pharmaceuticals. Defense and prosecution of legal claims can be 
expensive and time consuming and may adversely affect the Company regardless of the outcome due to the diversion 
of financial, management and other resources away from the Company’s primary operations. Negative judgments against 
the Company, even if the Company is planning to appeal such a decision, or even a settlement in a case, could negatively 
affect the cash reserves of the Company, and could have a material negative effect on the development of its drug 
products. 
 
The Company may be exposed, in particular, to liability claims which are uninsured or not sufficiently insured, and any 
claims may adversely affect the Company’s ability to obtain insurance in the future or result in negative publicity regarding 
the efficacy of its drug products. Such liability insurance is expensive, its ability is limited, and it may not be available on 
terms that are acceptable to the Company, if at all. 
 
The use of any of the Company’s unapproved products under development, the use of its products in clinical trials, and, 
if regulatory approval is received, the sale of such products, may expose the Company to liability claims which could 
materially adversely affect the Company’s business. The Company may not be able to maintain or obtain commercially 
reasonable liability insurance for future products, and any claims under any insurance policies may adversely affect its 
ability to maintain existing policies or to obtain new insurance on existing or future products. Even with adequate 
insurance coverage, publicity associated with any such claim could adversely affect public opinion regarding the safety 
or efficacy of the Company’s products. As a result, any product liability claim or recall, including in connection with 
products previously sold by the Company through its former distribution business, could materially adversely affect the 
Company’s business. 
 
If the Company were unable to maintain product liability insurance required by third parties, the corresponding 
agreements would be subject to termination, which could have a material adverse impact on our operations 
 

36 
 
Some of our licensing and other agreements with third parties require or might require us to maintain product liability 
insurance. If the Company cannot maintain acceptable amounts of coverage on commercially reasonable terms in 
accordance with the terms set forth in these agreements, the corresponding agreements would be subject to termination, 
which could have a material adverse impact on the Company’s operations. 
 
The Company is dependent upon key personnel; Director residency requirements 
 
The Company’s ability to continue its development of potential products depends on its ability to attract and maintain 
qualified key individuals to serve in management and on the Board. However, the Company does not currently have a 
formal succession plan for members of its senior management team or for its Board and, because competition for qualified 
key individuals with experience relevant to the industry in which the Company operates is intense, the Company may not 
be able to attract and/or retain such personnel. Additionally, applicable corporate law requires that at least 25% of the 
Company’s directors be resident Canadians, and the Company’s articles provide that the Company cannot have fewer 
than four directors at any time.  
 
Consequently, if the Company is unable to attract and/or loses and is unable to replace key personnel, its business could 
be negatively affected and, in particular, if the Company loses its current resident Canadian director in the future and is 
unable to find a resident Canadian director to fill the resulting vacancy, the Board will be prevented from taking any action 
other than appointing an additional resident Canadian director until such time as a new resident Canadian director has 
been appointed such that at least 25% of the Company’s directors are resident Canadians.  
 
The Company employs a small number of employees who have many years of technical knowledge of the Company’s 
technology and two senior officers, the CEO and CFO. COVID-19 imposes a high risk to all of the Company’s activities. 
The Company has established a policy to diligently monitor developments. Because the situation is fluid, the Company 
will be updating its staff whenever necessary. The Company has implemented and communicated a policy to all staff in 
order mitigate any potential risk. 
 
In addition, the Company does not carry key-person insurance on any individuals. 
 
The Company’s employees and consultants may engage in misconduct or other improper activities, including non-
compliance with regulatory standards and requirements, which could have a material adverse effect on the Company’s 
business 
 
The Company is exposed to the risk of employee and consultant fraud or other misconduct. Misconduct by employees 
and consultants could include but are not limited to the following: failure to comply with regulators, failure to provide 
accurate information, failure to comply with manufacturing standards the Company has established, jurisdictional 
healthcare fraud and abuse of laws and regulations, failure to report financial information or data accurately or disclose 
unauthorized activities. For example, sales, marketing and business arrangements in the healthcare industry are subject 
to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing, and other abusive practices. These 
laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales 
commission, customer incentive programs and other business arrangements. Employee and consultant misconduct could 
also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory 
sanctions and serious harm to the Company’s reputation. If any such actions are instituted against the Company, and the 
Company is not successful in defending itself or asserting its rights, those actions could have a substantial impact on the 
Company’s business and operating results, including the imposition of substantial fines, halt in trading of the Common 
Shares, possible delisting and/or other sanctions. 
 
Indemnification obligations to directors and officers of the Company may adversely affect the Company’s finances 
 
The Company has entered into agreements pursuant to which the Company has agreed to indemnify its directors and 
senior management in respect of certain claims made against them while acting in their capacity as such. If the Company 
is called upon to perform its indemnity obligations, its finances may be adversely affected. 
 
The Company’s finances may fluctuate based on foreign currency exchange rates 
 
The Company operates internationally and is exposed to foreign exchange risks from various currencies, primarily the 
U.S. dollar, the Euro and the Polish Zloty. Fluctuations in the value of foreign currencies relative to the Canadian dollar 
could cause us to incur currency exchange losses. 
 
The Company may incur losses due to adverse decisions by tax authorities or changes in law 
The Company’s income tax reporting is subject to audit by tax authorities. The effective tax rate may change from year 
to year based on the mix of income; non-deductible expenses; changes in tax law; and changes in the estimated values 
of future income tax assets and liabilities. 

37 
 
The Company may enter into transactions and arrangements in the ordinary course of business in which the tax treatment 
is not entirely certain. The Company must therefore make estimates and judgments in determining its consolidated tax 
provision. The final outcome of any audits by taxation authorities may differ from estimates and assumptions used in 
determining the consolidated tax provisions and accruals. This could result in a material effect on the Company’s scientific 
research and experimental development tax credits, income tax provision, financial position and the net income/loss for 
the period in which such determinations are made. 
The Company is subject to taxation in Canada. The Company’s effective tax rate and tax liability are determined by a 
number of factors, including the amount of taxable income, the tax rates, The application of these tax laws and related 
regulations is subject to legal and factual interpretation, judgment and uncertainty. An adverse interpretation or ruling by 
a taxing authority in a jurisdiction in which the Company operates or a change in law could increase the Company’s tax 
liability or result in the imposition of penalty payments, which could adversely impact the Company’s operating results. 
The requirements of being a public company may strain the Company’s resources, divert management’s attention and 
affect its ability to attract and retain qualified board members 
The Company’s Common Shares are publicly traded on the TSX. As a public company, the Company is subject to the 
reporting requirements of Canadian securities regulators, the listing requirements of any stock exchange on which its 
Common Shares are listed for trading and other applicable securities rules and regulations. Compliance with these rules 
and regulations may increase the Company’s legal and financial compliance costs, may make some activities more 
difficult, time-consuming or costly and may increase the demand on the Company’s systems and resources. Being a 
public company requires that the Company file continuous disclosure documents, including, among other things, annual 
and quarterly financial statements. Management’s attention may be diverted from other business concerns, which could 
have a material adverse effect on the Company’s business, financial condition and results of operations. The Company 
may need to hire more employees in the future, which will increase its costs and expenses. 
In addition, changing laws, regulations and standards relating to corporate governance and public disclosure create 
uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time 
consuming. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by 
ongoing revisions to disclosure and governance practices. The Company may invest resources to comply with evolving 
laws, regulations and standards, and this investment may result in increased general and administrative expenses and 
a diversion of management’s time and attention from revenue-generating activities to compliance activities. If the 
Company’s efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory 
authorities, legal proceedings may be initiated against the Company and its business may be harmed. 
General economic conditions may have an adverse effect on the Company and its business 
 
Continuing global economic volatility and uncertainty may have an adverse effect on the Company and its business, 
including without limitation the ability to raise additional financing, to obtain strategic partner support or commercialization 
opportunities and alliances for the Company’s new drug candidates, and to obtain continued services and supplies. 
 
The Company’s business involves environmental risks that could result in accidental contamination, injury, and 
significant capital expenditures in order to comply with environmental laws and regulations 
 
The Company and its commercial collaborators are subject to laws and regulations governing the use, manufacture, 
storage, handling and disposal of materials and certain waste products. Although the Company believes that its safety 
procedures comply with the regulations, the risk of accidental contamination or injury from these materials cannot be 
eliminated. In the event of such an accident, the Company could be held liable for any damages that result and any such 
liability could exceed the resources of the Company. The Company is not specifically insured with respect to this liability. 
The Company (or its collaborators) may be required to incur significant costs to comply with environmental laws and 
regulations in the future; and the operations, business or assets of the Company may be materially adversely affected 
by current or future environmental laws or regulations. 
 
Any failure to maintain an effective system of internal controls may result in material misstatements of the Company’s 
consolidated financial statements or cause us to fail to meet the Company’s reporting obligations or fail to prevent fraud; 
and in that case, the Company’s shareholders could lose confidence in the Company’s financial reporting, which would 
harm the Company’s business, could negatively impact the price of the Common Shares and prevent the Company from 
raising additional capital 
 
Effective internal controls are necessary for the Company to provide reliable financial reports and prevent fraud. If the 
Company fails to maintain an effective system of internal controls, the Company may not be able to report its financial 
results accurately or prevent fraud; and in that case, the Company’s shareholders could lose confidence in the Company’s 
financial reporting, which would harm the Company’s business, negatively impact the price of the Common Shares and 
also prevent the Company from raising additional capital. Even if the Company were to conclude that its internal control 
over financial reporting provides reasonable assurance regarding the reliability of financial reporting and the preparation 
of consolidated financial statements for external purposes in accordance with IFRS as issued by the IASB, because of 

38 
 
its inherent limitations, internal control over financial reporting may not prevent or detect fraud or misstatements. Failure 
to achieve and maintain effective internal control over financial reporting could prevent the Company from complying with 
its reporting obligations on a timely basis, which could result in the loss of investor confidence in the reliability of the 
Company’s consolidated financial statements, harm the Company’s business, negatively impact the trading price of the 
Common Shares and prevent the Company from raising additional capital. 
 
Our results of operations may be negatively impacted by the COVID-19 outbreak 
 
The Company’s business, operations and financial condition could be materially and adversely affected by the outbreak 
of epidemics or pandemics or other health crises, including the COVID-19 pandemic. As a result of the COVID-19 
outbreak, the Company may experience disruptions that could severely impact its business, preclinical studies and 
clinical trials, including: 
 
 
delays or difficulties in enrolling patients in our clinical trials; 
 
delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical 
site staff; 
 
interruption of key clinical trial activities, such as clinical trial site data monitoring, due to limitations on travel imposed 
or recommended by federal, provincial or state governments, employers and others or interruption of clinical trial 
subject visits and study procedures, which may impact the integrity of subject data and clinical study endpoints; 
 
interruption or delays in the operations of the FDA, which may impact approval timelines; 
 
interruption of, or delays in receiving supplies of our product candidates from our contract manufacturing 
organizations due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems; 
and 
 
limitations on employee resources that would otherwise be focused on the conduct of our preclinical studies and 
clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact 
with large groups of people. 
 
In addition, the trading prices for the Common Shares and the securities of other biopharmaceutical companies have 
been highly volatile as a result of the COVID-19 epidemic. As a result, the Company may face difficulties raising capital 
through sales of our securities, and such sales may be on unfavorable terms, if at all. The COVID-19 outbreak continues 
to rapidly evolve. The extent to which the outbreak may impact our business, preclinical studies and clinical trials will 
depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate 
geographic spread of the disease, the duration of the outbreak, travel restrictions and other measures implemented in 
Canada, the United States and other countries, business closures or business disruptions and the effectiveness of actions 
taken in the Canada, the United States and other countries to contain the disease.  
 
The spread of COVID-19 has resulted in a sharp decline in global economic growth as well as causing increased volatility 
and declines in financial markets. If the COVID-19 pandemic is prolonged, or further diseases emerge that give rise to 
similar effects, the adverse impact on the global economy could deepen and result in further declines in global economic 
growth and financial markets. Accordingly, the full impact of the COVID-19 pandemic on the global economy and financial 
markets is uncertain and may have an adverse effect on the Company. 
 
To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of 
heightening many of the other risks described in this AIF. Because of the highly uncertain and dynamic nature of events 
relating to the COVID-19 pandemic, it is not currently possible to estimate the impact of COVID-19 on the Company. 
However, these effects could have a material impact on our business, operations and financial condition. 
 
The Russia Ukraine war 
 
The recent escalation of war in Ukraine, where the Company enrolled virtually all its patients in a clinical study, has 
complicated matters. As at the date of this MD&A, it is uncertain as to when the clinical study reports will be completed, 
if at all. 
 
Risks Related to the Common Shares 
 
The Company’s share price and trading volumes are volatile and the Company may have difficulty maintaining listing 
requirements 
 
The market price of the Company’s Common Shares, as well as market prices for securities of biopharmaceutical and 
drug delivery companies generally, have historically been highly volatile, and have from time to time experienced 
significant price and volume fluctuations that are unrelated to the operating performance of particular companies.  
 
The trading price of the Common Shares is subject to change and could in the future fluctuate significantly. The 
fluctuations could be in response to numerous factors beyond the Company’s control, including but not limited to, the 
following: 

39 
 
 
actual or anticipated fluctuations in the Company’s quarterly results of operations; 
 
recommendations by securities research analysts; 
 
changes in the economic performance or market valuations of companies in the industry in which the Company 
operates; 
 
addition or departure of the Company’s executive officers and other key personnel; 
 
release or expiration of transfer restrictions on outstanding Common Shares; 
 
sales or perceived sales of additional Common Shares; 
 
operating and financial performance that vary from the expectations of management, securities analysts and 
investors; 
 
regulatory changes affecting the Company’s industry generally and its business and operations; 
 
announcements of developments and other material events by the Company or its competitors; 
 
fluctuations to the costs of vital production materials and services; 
 
changes in global financial markets and global economies and general market conditions, such as interest rates and 
pharmaceutical product price volatility; 
 
significant acquisitions or business combinations, strategic partnerships, joint ventures or capital commitments by or 
involving the Company or its competitors; 
 
operating and share price performance of other companies that investors deem comparable to the Company or from 
a lack of market comparable companies;  
 
news reports relating to trends, concerns, technological or competitive developments, regulatory changes and other 
related issues in the Company’s industry or target markets; and the outbreak of epidemics, pandemics or other 
health crises including COVID-19. 
 
The Internet offers various avenues for the dissemination of information. The Company has no control over the 
information that is distributed and discussed on electronic bulletin boards and investment chat rooms. The intention of 
the people or organizations that distribute such information may not be in the Company’s best interest and the best 
interests of its shareholders. This, in addition to other forms of investment information including newsletters and research 
publications, could result in a sharp decline in the market price of the Common Shares. 
In addition, stock markets have occasionally experienced extreme price and volume fluctuations. The market prices for 
high-technology companies have been particularly affected by these market fluctuations and such effects have often 
been unrelated to the operating performance of such companies. These broad market fluctuations may cause a decline 
in the market price of the Common Shares. 
Sales of substantial numbers of the Company’s Common Shares could cause a decline in the market price of such 
Common Shares. There are minimum listing requirements for an issuer to maintain its listing on the TSX, and if the 
Company fails to maintain these listing requirements, it may be involuntarily delisted from the TSX. De-listing the 
Company or the Company shares from any securities exchange could have a negative effect on the liquidity of the 
Company shares and/or the ability of a shareholder to trade in shares of the Company, and could have an adverse effect 
on the Company’s ability to raise future equity financings. The Company’s Common Shares trade in a very low volume 
compared to the number of Common Shares outstanding. This means a shareholder could have difficulty disposing of 
Common Shares, especially if there are other shareholders of the Company trying to sell their shares in the Company at 
the same time. Volatility in share price and trading volumes could have an adverse effect on the Company’s ability to 
raise future equity financings. 
 
Shareholders of the Company may face dilution from future equity or convertible debt financings or through the exercise 
of stock options, warrants or other securities convertible or exchangeable into Common Shares 
 
To attract and retain key personnel, the Company has granted options to its key employees, directors and consultants to 
purchase Common Shares as non-cash incentives. In addition, the Company has a significant number of warrants to 
purchase Common Shares outstanding. The issuance of shares pursuant to the exercise of a significant number of such 
options and/or warrants may result in significant dilution to other shareholders of the Company. 
 
As noted above, the Company needs additional funding and has historically turned to the equity markets to raise this 
funding. The future sale of equity securities and warrants may also result in significant dilution to the shareholders of the 
Company. 
 
The Company cannot predict the size or nature of future sales or issuances of securities or the effect, if any, that such 
future sales and issuances will have on the market price of the Common Shares. Sales or issuances of substantial 
numbers of Common Shares or other securities that are convertible or exchangeable into Common Shares, or the 
perception that such sales or issuances could occur, may adversely affect prevailing market prices of the Common 
Shares. With any additional sale or issuance of Common Shares or other securities that are convertible or exchangeable 
into Common Shares, investors will suffer dilution to their voting power and economic interest in the Company. 
Furthermore, to the extent holders of the Company’s stock options or other convertible securities convert or exercise 
their securities and sell the Common Shares they receive, the trading price of the Common Shares may decrease due 
to the additional amount of Common Shares available in the market. 
 

40 
 
Trading in the Company’s Common Shares outside of Canada may be subject to restrictions on trading under foreign 
securities laws, and purchasers of securities under private placements by the Company will be subject to certain 
restrictions on trading 
 
The Company’s Common Shares trade on the TSX and are freely tradeable only in Canada. As such, shareholders 
trading the Common Shares outside of Canada may be subject to restrictions imposed by foreign securities laws that 
may restrict their ability to transfer shares freely or at all. Certain securities offered by the Company pursuant to its private 
placements, including the unlisted warrants issued by the Company, are subject to certain initial hold periods and other 
restrictions on trading imposed by applicable securities laws and, in the case of the warrants, pursuant to the terms of 
the applicable warrant certificates. These restrictions may affect the liquidity of the investment of certain shareholders in 
the securities of the Company. 
 
The Company does not expect to pay any cash dividends for the foreseeable future 
 
Investors should not rely on an investment in the Common Shares to provide dividend income. The Company does not 
anticipate that it will pay any cash dividends to holders of the Common Shares in the foreseeable future. Instead, the 
Company plans to retain any earnings to maintain and expand its operations. In addition, any future debt financing 
arrangement may contain terms prohibiting or limiting the amount of dividends that may be declared or paid on the 
Common Shares. Accordingly, investors must rely on sales of their Common Shares after price appreciation, which may 
never occur, as the only way to realize any return on their investment. As a result, investors seeking cash dividends 
should not purchase Common Shares. 
 
If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research about the 
Company’s business, the share price and trading volume of the Common Shares could decline 
 
The trading market for the Common Shares will depend, in part, on the research and reports that securities or industry 
analysts publish about the Company or its business. If one or more of the analysts who cover the Company downgrade 
the Common Shares or publish inaccurate or unfavorable research about the Company’s business, the Company’s share 
price would likely decline. In addition, if the Company’s operating results fail to meet the forecast of analysts, the 
Company’s share price would likely decline. If one or more of these analysts cease coverage of the Company or fail to 
publish reports on the Company regularly, demand for the Common Shares could decrease, which might cause the share 
price and trading volume of the Common Shares to decline. 
 
RISK FACTORS IN OTHER PUBLIC FILINGS 
 
For all of the reasons set forth above, together with those additional risk factors identified under the headings “Forward-Looking 
Statements” and “Risk Factors” in the Company’s most recent Annual Information Form filed under the Company’s profile on

INDEPENDENT AUDITOR’S REPORT 
To the Shareholders and Board of Directors of  
Helix BioPharma Corp. 
Opinion  
We have audited the financial statements of Helix BioPharma Corp. (the “Company”), which 
comprise the statements of financial position as at July 31, 2022 and 2021, and the statements of 
net loss and comprehensive loss, changes in shareholders’ equity (deficiency) and cash flows for 
the years then ended, and notes to the financial statements, including a summary of significant 
accounting policies and other explanatory information.  
In our opinion, the accompanying financial statements present fairly, in all material respects, the 
financial position of the Company as at July 31, 2022 and 2021 and its financial performance and 
its cash flows for the years then ended in accordance with International Financial Reporting 
Standards as issued by International Accounting Standards Board (“IFRS”). 
Basis for Opinion 
We conducted our audit in accordance with Canadian generally accepted auditing standards. Our 
responsibilities under those standards are further described in the Auditor’s Responsibilities for 
the Audit of the Financial Statements section of our report. We are independent of the Company 
in accordance with the ethical requirements that are relevant to our audit of the financial 
statements in Canada, and we have fulfilled our other ethical responsibilities in accordance with 
these requirements. We believe that the audit evidence we have obtained is sufficient and 
appropriate to provide a basis for our opinion. 
Material Uncertainty Related to Going Concern 
We draw attention to Note 1 in the financial statements, which indicates that the Company 
incurred a net loss and comprehensive loss of $6,653,000 during the year ended July 31, 2022 
and, as of that date, the Company’s cash balance of $3,252,000 is insufficient to meet anticipated 
cash needs for working capital and capital expenditures through the next twelve months. As 
stated in Note 1, these events or conditions, along with other matters as set forth in Note 1, 
indicate that a material uncertainty exists that casts significant doubt on the Company's ability to 
continue as a going concern. Our opinion is not modified in respect of this matter. 

Key Audit Matters 
Key audit matters are those matters that, in our professional judgment, were of most significance 
in our audit of the financial statements for the year ended July 31, 2022. These matters were 
addressed in the context of our audit of the financial statements as a whole, and in forming our 
opinion thereon, and we do not provide a separate opinion on these matters. Except for the matter 
described in the Material Uncertainty Related to Going Concern section, we have 
determined that there are no other key audit matters to communicate in our report. 
Other Information 
Management is responsible for the other information. The other information comprises: 

The information, other than the financial statements and our auditor’s report thereon,
included in the 2022 Annual Report; and

The information included in Management’s Discussion and Analysis for the year ended
July 31, 2022.
Our opinion on the financial statements does not cover the other information and we do not 
express any form of assurance conclusion thereon. 
In connection with our audit of the financial statements, our responsibility is to read the other 
information identified above and, in doing so, consider whether the other information is 
materially inconsistent with the financial statements or our knowledge obtained in the audit, or 
otherwise appears to be materially misstated. 
We have obtained Management’s Discussion and Analysis and the 2022 Annual Report prior to 
the date of this auditor’s report. If, based on the work we have performed on the other 
information that we obtained prior to the date of this auditor’s report, we conclude that there is a 
material misstatement of this other information, we are required to report that fact. We have 
nothing to report in this regard.   
Responsibilities of Management and Those Charged with Governance for the Financial 
Statements 
Management is responsible for the preparation and fair presentation of the financial statements in 
accordance with IFRS, and for such internal control as management determines is necessary to 
enable the preparation of financial statements that are free from material misstatement, whether 
due to fraud or error. 
In preparing the financial statements, management is responsible for assessing the Company’s 
ability to continue as a going concern, disclosing, as applicable, matters related to going concern 
and using the going concern basis of accounting unless management either intends to liquidate 
the Company or to cease operations, or has no realistic alternative but to do so. 
Those charged with governance are responsible for overseeing the Company’s financial 
reporting process. 

 
 
Auditor’s Responsibilities for the Audits of the Financial Statements 
 
Our objectives are to obtain reasonable assurance about whether the financial statements as a 
whole are free from material misstatement, whether due to fraud or error, and to issue an 
auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but 
is not a guarantee that an audit conducted in accordance with Canadian generally accepted 
auditing standards will always detect a material misstatement when it exists. Misstatements can 
arise from fraud or error and are considered material if, individually or in the aggregate, they 
could reasonably be expected to influence the economic decisions of users taken on the basis of 
these financial statements. 
 
As part of an audit in accordance with Canadian generally accepted auditing standards, we 
exercise professional judgment and maintain professional skepticism throughout the audit. We 
also: 
 
 Identify and assess the risks of material misstatement of the financial statements, whether 
due to fraud or error, design and perform audit procedures responsive to those risks, and 
obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. 
The risk of not detecting a material misstatement resulting from fraud is higher than for 
one resulting from error, as fraud may involve collusion, forgery, intentional omissions, 
misrepresentations, or the override of internal control. 
 
 Obtain an understanding of internal control relevant to the audit in order to design audit 
procedures that are appropriate in the circumstances, but not for the purpose of 
expressing an opinion on the effectiveness of the Company’s internal control. 
 
 Evaluate the appropriateness of accounting policies used and the reasonableness of 
accounting estimates and related disclosures made by management. 
 
 Conclude on the appropriateness of management’s use of the going concern basis of 
accounting and, based on the audit evidence obtained, whether a material uncertainty 
exists related to events or conditions that may cast significant doubt on the Company’s 
ability to continue as a going concern. If we conclude that a material uncertainty exists, 
we are required to draw attention in our auditor’s report to the related disclosures in the 
financial statements or, if such disclosures are inadequate, to modify our opinion. Our 
conclusions are based on the audit evidence obtained up to the date of our auditor’s 
report. However, future events or conditions may cause the Company to cease to continue 
as a going concern. 
 
 Evaluate the overall presentation, structure and content of the financial statements, 
including the disclosures, and whether the financial statements represent the underlying 
transactions and events in a manner that achieves fair presentation. 
 
We communicate with those charged with governance regarding, among other matters, the 
planned scope and timing of the audit and significant audit findings, including any significant 
deficiencies in internal control that we identify during our audit. 
 

We also provide those charged with governance with a statement that we have complied with 
relevant ethical requirements regarding independence, and to communicate with them all 
relationships and other matters that may reasonably be thought to bear on our independence, and 
where applicable, related safeguards. 
From the matters communicated with those charged with governance, we determine those 
matters that were of most significance in the audit of the consolidated financial statements of the 
current period and are therefore the key audit matters. We describe these matters in our auditor’s 
report unless law or regulation precludes public disclosure about the matter or when, in 
extremely rare circumstances, we determine that a matter should not be communicated in our 
report because the adverse consequences of doing so would reasonably be expected to outweigh 
the public interest benefits of such communication. 
The engagement partner on the audit resulting in this independent auditor’s report is Jason Moi.

Notes to Annual Financial Statements 
For the years ended July 31, 2022 and 2021 
Tabular dollar amounts in thousands of Canadian dollars, except per common share figures 
 
 
 
 
 
Helix BioPharma Corp. (the “Company”), incorporated under the Canada Business Corporations Act, is an immune-oncology 
company primarily focused in the areas of cancer prevention and treatment. The Company has funded its research and 
development activities, mainly through the issuance of common shares and warrants. The Company expects to incur additional 
losses and therefore will require additional financial resources, on an ongoing basis. It is not possible to predict the outcome of 
future research and development activities or the financing thereof. 
 
The Company is a Canadian corporation domiciled in Canada. Our shares are publicly traded on the Toronto Stock Exchange 
(the “TSX”). Our principal place of business is located at 401 Bay Street, Suite 2704, Toronto, Ontario, Canada. 
 
1. 
Basis of presentation and going concern 
These annual financial statements have been prepared on a going-concern basis, which assumes that the Company will continue 
in operation for the foreseeable future and, accordingly, will be able to realize its assets and discharge its liabilities in the normal 
course of operations.  The Company's ability to continue as a going concern is dependent mainly on obtaining additional financing.  
The Company does not have sufficient cash to meet anticipated cash needs for working capital and capital expenditures through 
the next twelve months.  
 
The Company reported a net loss and total comprehensive loss of $6,563,000 for the year ended July 31, 2022, (July 31, 2021 
– $8,038,000).  As at July 31, 2022 the Company had working capital of $283,000, shareholders’ equity of $319,000, cash of 
$3,252,000 and an accumulated deficit of $195,117,000. As at July 31, 2021, the Company had working capital of $144,000, 
shareholders’ deficiency of $1,393,000, cash of $3,565,000 and an accumulated deficit of $188,554,000. The Company will require 
additional financing in the immediate near term and in the future to see the current research and development initiatives through 
to completion. There can be no assurance however, that additional financing can be obtained in a timely manner, or at all. 
 
 
Not raising sufficient additional financing on a timely basis may result in delays and possible termination of all or some of the 
Company’s research and development initiatives, and as a result, casts significant doubt as to the ability of the Company to 
operate as a going concern and accordingly, the appropriateness of the use of the accounting principles applicable to a going 
concern.  These annual financial statements do not include any adjustments to the carrying amount and classification of reported 
assets, liabilities and expenses that might be necessary should the Company not be successful in its aforementioned initiatives.  
Any such adjustments could be material.  The Company cannot predict whether it will be able to raise the necessary funds it needs 
to continue as a going concern. 
 
Statement of compliance  
The Company’s annual financial statements have been prepared in accordance with International Financial Reporting Standards 
(“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and interpretations of the International Financial 
Reporting Interpretation Committee. 
 
The policies applied in these annual financial statements are based on IFRS as issued by the International Accounting Standards 
Board. 
 
The annual financial statements of the Company were approved and authorized for issue by the board of directors of the Company 
(the “Board”) on October 31, 2022. 
 
Use of estimates and critical judgments 
The preparation of the Company’s financial statements requires management to make critical judgments, estimates and assumptions 
that affect the reported amounts of expenses, assets and liabilities, and the disclosure of contingent liabilities, at the reporting 
date. On an ongoing basis, management evaluates its judgments, estimates and assumptions using historical experience and 
various other factors it believes to be reasonable under the given circumstances. Actual outcomes may differ from these 
estimates that could require a material adjustment to the reported carrying amounts in the future. 
 
The Company has also assessed the impact of the coronavirus pandemic (“COVID-19”) on estimates and critical judgments.  
Although the Company expects COVID-19 related disruptions to continue into the Company’s fiscal 2023 year, the Company 
believes that the long-term estimates and assumptions do not require significant revisions. Although the Company determined 
that no significant revisions to such estimates, judgments or assumptions were required, the impact of COVID-19 is fluid and given 
the inherent uncertainty at this time, revisions may be required in future periods to the extent that the negative impacts on the 
Company’s business operations arising from COVID-19 continue or become worse.  Any such revision could result in a material 
impact on the Company’s financial performance and financial condition.

The most significant critical estimates and judgments made by management include the following: 
 
a) 
Going Concern 
Significant judgments related to the Company’s ability to continue as a going concern are disclosed in the first paragraph above 
in Note 1. 
 
b) 
Clinical study expenses 
Clinical study expenses are accrued based on services received and efforts expended pursuant to contracts with contract research 
organizations (“CROs”), consultants, clinical study sites and other vendors. In the normal course of business, the Company 
contracts with third parties to perform various clinical study activities.  The financial terms of these agreements vary from contract 
to contract and are subject to negotiations that may result in uneven payment outflows.  Payments under the contracts depend on 
various factors such as the achievement of certain events, the successful enrollment of patients or the completion of portions of 
the clinical study and/or other similar conditions. The Company determines the accruals by reviewing contracts, vendor 
agreements and purchase orders, and through discussions with internal personnel and external providers as to the progress or 
stage of completion of the clinical studies or services and the agreed-upon fee to be paid for such services.  However, actual costs 
and timing of the Company’s clinical studies is uncertain, subject to risk and may change depending upon a number of factors, 
including the Company’s clinical development plans and trial protocols. 
 
c) 
Valuation of share-based compensation and warrants 
Management measures the costs for share-based compensation and warrants using market-based option valuation techniques. 
Assumptions are made and estimates are used in applying the valuation techniques. These include estimating the future volatility 
of the share price, expected dividend yield, future employee turnover rates, and future exercise behaviours. Such estimates 
and assumptions are inherently uncertain. Changes in these assumptions affect the fair value estimates of share-based payments 
and warrants. 
 
d) 
Income taxes 
Deferred tax assets, including those arising from unutilized tax losses, require management to assess the likelihood that the 
Company will generate future taxable income in future years in order to utilize any deferred tax asset which has been 
recognized. Estimates of future taxable income are based on forecasted cash flows. At the current statement of financial position 
date, no deferred tax assets have been recognized in these annual financial statements. 
 
e) 
Fair value of convertible note payable 
In determining the fair values of the convertible note payable for the initial recognition the Company used a Black-Scholes model 
with the following assumptions: volatility rate, risk-free rate and the remaining expected life. The inputs used in the model are taken 
from observable markets. In particular, changes in the fair value of the convertible note payable can have a material impact on the 
reported loss and comprehensive loss for the applicable reporting period. As at July 31, 2022, the fair value of the convertible note 
payable was measured at its face value less all converted amounts, which the Company determined approximated fair value. 
 
Functional and presentation currency 
The functional and presentation currency of the Company is the Canadian dollar. 
 
2. 
Significant accounting policies 
The accounting policies set out below have been applied consistently to all periods presented in these annual financial statements. 
 
Basis of consolidation 
Helix Immuno-Oncology S.A. (“HIO”) was incorporated on July 6, 2013 in Poland. As at July 31, 2020, the Company’s investment 
in HIO was consolidated and classified as held for sale and was presented as discontinued operations.  At September 3, 2020, 
HIO completed a direct financing with an arm’s length party. As a result, the Company determined that it had lost control of HIO 
and deconsolidated HIO from the Company’s financial statements. On December 22, 2020, the Company disposed of its remaining 
interest in HIO. At July 31, 2021 and as of the date of these annual financial statements, the Company no longer has any 
subsidiaries. See Note 15 – Deconsolidation of subsidiary held for sale, for further information. 
 
Cash 
The Company considers cash on hand, bank deposits and bank term deposits with maturities of 90 days or less as cash.

Leases 
The Company recognizes a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is 
initially measured at cost. Subsequent to initial application, the right-of-use asset is measured at cost less any accumulated 
depreciation and impairment losses and adjusted for certain remeasurements of the lease liability.  In comparison, the lease 
liability is increased by the interest cost on the lease liability and decreased by lease payments made. It is remeasured when there 
is a change in future lease payments arising from a change in an index or rate, a change in the estimate of the amount expected 
to be payable under a residual value guarantee, or as appropriate, changes in the assessment of whether a purchase or extension 
option is reasonably certain to be exercised or a termination option is reasonably certain to be exercised or a termination option 
is reasonably certain not to be exercised. 
 
The Company has applied judgment to determine the lease term for some lease contracts in which it is a lessee that include 
renewal options.  The assessment of whether the Company is reasonably certain to exercise such options impacts the lease term, 
which significantly affects the amount of lease liabilities and right-of-use assets recognized. 
 
Research and development costs 
Research costs are expensed as incurred.  Development costs are expensed as incurred except for those which meet the criteria 
for deferral, in which case, the costs are capitalized and amortized to operations over the estimated period of benefit.  No costs 
have been deferred to date. 
 
Investment tax credits 
The Company is entitled to Canadian federal and provincial investment tax credits, which are earned as a percentage of eligible 
research and development expenditures incurred in each taxation year.  Investment tax credits are accounted for as a reduction 
of the related expenditure for items of a current nature and a reduction of the related asset cost for items of a capital nature, 
provided that the Company has reasonable assurance that the tax credits will be realized. 
 
Stock-based compensation 
The Company accounts for stock-based compensation and other stock-based payments awarded to employees in accordance 
with the fair value method.  The fair value of stock options granted is determined at the appropriate measurement date using the 
Black-Scholes option pricing model, and generally expensed over the options’ vesting period for employee awards.  Awards with 
graded vesting are considered multiple awards for fair value measurement and stock-based compensation calculation.  In 
determining the expense, the Company accounts for forfeitures using an estimate based on historical trends.  When stock-based 
compensation and other stock-based payments are awarded to persons other than non-employees, share capital is increased for 
the fair value of goods and services received. 
 
Foreign currency translation 
The Company’s currency of presentation is the Canadian dollar, which is also the Company’s functional currency.  Foreign 
currency-denominated items are translated into Canadian dollars.  Monetary assets and liabilities in foreign currencies are 
translated into Canadian dollars at the rates of exchange in effect at the balance sheet dates.  Non-monetary items are translated 
at historical exchange rates.  Revenue and expenses are translated at the exchange rates prevailing at their respective transaction 
dates.  Exchange gains and losses arising on translation are included in income. 
 
Income taxes 
The Company follows the asset and liability method of accounting for income taxes.  Under this method, deferred income tax 
assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement 
carrying amounts of certain existing assets and liabilities and their respective tax bases.  Deferred income tax assets and liabilities 
are measured using enacted or substantively enacted tax rates expected to apply to taxable income in the years in which those 
temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax 
rates is recognized in income in the period that includes the date of substantive enactment.  Given the Company’s history of net

losses and expected future losses, the Company is of the opinion that it is probable that these tax assets will not be realized in 
the foreseeable future and therefore, the deferred tax asset has not been recognized. 
 
Financial instruments 
The Company recognizes a financial asset or financial liability when it becomes party to the contractual provisions of the financial 
instrument. Financial assets are initially measured at fair value and are derecognized either when the Company has transferred 
substantially all the risks and rewards of ownership of the financial asset, or when cash flows expire. Financial liabilities are 
initially measured at fair value and are derecognized when the obligation specified in the contract is discharged, cancelled or 
expired. 
 
A write-off of a financial asset (or a portion thereof) constitutes a derecognition event. Write-offs occur when the Company has 
no reasonable expectations of recovering the contractual cash flows on a financial asset. 
 
The Company determines the classification of its financial instruments at initial recognition. Financial assets are classified 
according to the following measurement categories: 
 
i) amortized cost; or 
ii) those to be measured subsequently at fair value, either through profit or loss (“FVTPL”) or through 
other comprehensive income (“FVTOCI”). 
 
The classification and measurement of financial assets after initial recognition at fair value depends on the business model 
for managing the financial asset and the contractual terms of the cash flows. Financial assets that are held within a business 
model whose objective is to collect the contractual cash flows, and that have contractual cash flows that are solely payments of 
principal and interest on the principal outstanding, are generally measured at amortized cost at each subsequent reporting period. 
All other financial assets are measured at their fair values at each subsequent reporting period, with any changes recorded 
through profit or loss or through other comprehensive income (which designation is made as an irrevocable election at the time 
of recognition). 
 
After initial recognition at fair value, financial liabilities are classified and measured at either: 
 
i) amortized cost; or 
ii) FVTPL, if the Company has made an irrevocable election at the time of recognition, or when required (for 
items such as instruments held for trading or derivatives). 
 
The Company reclassifies financial assets only when its business model for managing those assets changes. Financial liabilities 
are not reclassified. 
 
Transaction costs that are directly attributable to the acquisition or issuance of a financial asset or financial liability subsequently 
measured at amortized cost or FVTOCI are included in the fair value of the instrument on initial recognition. Transaction costs for 
financial assets and financial liabilities classified at fair value through profit or loss are expensed in profit or loss. 
 
The Company classifies its financial instruments by category according to their nature and their characteristics. Management 
determines the classification when the instruments are initially recognized, which is normally the date of the transaction. The 
Company classifies its financial assets and financial liabilities as outlined below: 
 
Asset / Liability 
Classification 
 
Cash 
Amortized Cost 
Account receivable 
Amortized Cost 
Accounts payable 
Amortized Cost 
Accrued liabilities 
Amortized Cost 
Convertible note payable 
FVTPL 
 
 
The Company assesses all information available, including on a forward-looking basis the expected credit losses associated 
with any financial assets carried at amortized cost. The impairment methodology applied depends on whether there has been a 
significant increase in credit risk. To assess whether there is a significant increase in credit risk, the Company compares the risk 
of a default occurring on the asset as at the reporting date with the risk of default as at the date of initial recognition based on all 
information available, and reasonable and supportive forward-looking information. 
 
An embedded derivative is separated from the host contract and recognized separately if the economic characteristics and 
risks of the embedded derivative are not closely related to those of the host, if a separate instrument with the same terms

11 
 
as the embedded derivative would meet the definition of a derivative, and if the combined instrument is not measured at fair 
value, with changes in fair value recognized in profit or loss. 
 
The fair value of a financial instrument is the amount of consideration that would be agreed upon in an arm’s-length transaction 
between knowledgeable, willing parties who are under no compulsion to act. Fair values are determined based on prevailing market 
rates for instruments with similar characteristics and risk profiles. 
 
The Company categorizes its fair value measurements according to a three-level hierarchy. The hierarchy prioritizes the inputs 
used by the Company’s valuation techniques. A level is assigned to each fair value measurement based on the lowest-level 
input significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are defined as follows: 
 
Level 1 – unadjusted quoted prices as at the measurement date for identical assets or liabilities in active markets. 
Level 2 – observable inputs other than quoted prices included in level 1, such as quoted prices for similar assets 
and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not 
active, or other inputs that are observable or can be corroborated by observable market data. 
Level 3 – significant unobservable inputs that are supported by little or no market activity. 
 
The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable 
inputs when measuring fair value 
 
Basic and diluted loss per common share 
Basic loss per share is computed by dividing the net loss available to common shareholders by the weighted average number of 
shares outstanding during the reporting period.  Diluted loss per share is computed similarly to basic loss per share, except that 
the weighted average shares outstanding are increased to include additional shares for the assumed exercise of stock options 
and warrants, if dilutive.  The number of additional shares is calculated by assuming that outstanding stock options and warrants 
were exercised and that the proceeds from such exercises were used to acquire common shares at the average market price 
during the reporting periods.  The inclusion of the Company’s stock options and warrants in the computation of diluted loss per 
share has an anti-dilutive effect on the loss per share and, therefore, they have been excluded from the calculation of diluted loss 
per share. 
 
Government grants  
Government grant funds are recognised in income when there is reasonable assurance that the Company has complied with the 
conditions attached to them and that the grant funds will be received. Grant funds receivable are recognized in income over the 
periods in which the entity recognizes as expenses, the related costs for which the grant is intended to compensate. As at the 
date of these annual financial statements, the Company has received no government assistance.

Shareholders’ equity (deficiency) 
Preferred shares 
The Company is authorized to issue 10,000,000 preferred shares. As at July 31, 2022 the Company had nil preferred shares 
issued and outstanding (July 31, 2021 – nil). 
 
Common shares and share purchase warrants 
The Company is authorized to issue an unlimited number of common shares without par value. As at July 31, 2022 the Company 
had 171,794,753 common shares issued and outstanding (July 31, 2021 – 141,133,017).  
 
On December 4 and 30, 2020, the Company completed private placement financings of an aggregate of 8,200,000 units of the 
Company at a price of $0.50 per unit, for aggregate gross proceeds of $4,100,000. Each unit consisted of one common share and 
one common share purchase warrant. Each common share purchase warrant entitles the holder to purchase one common share 
at a price of $0.70 until December 3 and 29, 2025, respectively.  Of the gross proceeds amount of $4,100,000, approximately 
$1,333,000 was allocated to the share purchase warrants based on fair value and approximately $2,767,000 was allocated to the 
common shares.  Share issue costs totalling approximately $537,000 were proportionately allocated to the share purchase 
warrants ($174,000) and the common shares ($363,000), respectively.  See Note 14 – Deconsolidation of subsidiary held for sale 
for further information. 
 
On May 11, 2021, the Company entered into a definitive convertible security funding agreement (“the Funding Agreement”) with 
Lind Global Macro Fund, LP, a New York based institutional investment fund managed by The Lind Partners, LLC (collectively 
“Lind”). The Company closed the first tranche under the Funding Agreement on May 13, 2021 for gross proceeds of $3,500,000 
(the “First Tranche”). In connection with the closing of the First Tranche, the Company issued (i) an 8.75% convertible note (a 
“Convertible Security”) with a two-year term and a face value of $4,112,500 and (ii) an aggregate of 1,957,056 common share 
purchase warrants exercisable into 1,957,056 common shares until May 12, 2025 at an exercise price of $1.0283 per common 
share and classified as equity instruments. The approximate residual fair value of the share purchase warrants was estimated at 
approximately $30,000. In connection with the closing of the First Tranche, the Company paid Lind a 3% commitment fee of the 
amount funded under the First tranche. The Funding Agreement also contemplates the issuance of a second Convertible 
Debentures upon the mutual agreement of the Company and Lind for gross proceeds to the Company of up to $6,500,000 (the 
“Second Tranche”).  
 
As of July 31, 2022, Lind has converted an aggregate of $1,645,000 of the face value of the Convertible Security issued under the 
First Tranche into an aggregate of 6,764,798 common shares of the Company at an average deemed price of $0.2432 per common 
share. See Note 7 – Convertible note payable for additional information.

On March 11, 2022, the Company closed a private placement financing for gross proceeds of $1,001,000 from the issuance of 
3,850,000 common share at a price of $0.26 per common share. On April 21, 2022, the Company closed a private placement 
financing for net proceeds of $2,002,000 from the issuance of 7,700,000 common shares at a price of $0.26 per common share. 
 
On April 13, 2022, the Company announced that it had received conditional approval from the Toronto Stock Exchange to extend 
its previously announced Early Warrant Exercise Incentive Program from April 28, 2022, to May 31, 2022. The Incentive Program 
is a period during which holders of the Company’s eligible common share purchase warrants (“Eligible Warrants”) may take 
advantage of a temporary reduction in the exercise price of the Eligible Warrants to a price of C$0.26. The Eligible Warrants 
included an aggregate of 49,806,469 warrants that if exercised at the Incentive Exercise Price would have resulted in the Company 
receiving gross proceeds of up to $12,949,682. During the year ended July 31, 2022, 12,346,938 warrants were exercised for a 
total subscription amount of $3,210,204. As the modified equity warrants were originally accounted for under IAS 32 and remain 
equity classified after modification, the Company has elected to not record accounting entries that would have been within equity. 
 
The following table provides information on common share purchase warrants of the Company outstanding as at: 
 
 
Stock options 
The Company’s equity compensation plan reserves up to 10% of the Company’s outstanding common shares from time to time 
for granting to directors, officers and employees of the Company or any person or company engaged to provide ongoing 
management or consulting services.  Based on the Company’s current issued and outstanding common shares as at July 31, 
2022, options to purchase up to 17,179,475 common shares (July 31, 2021 – 14,113,302) may be granted under the plan. As at 
July 31, 2022, options to purchase a total of 9,050,000 common shares (July 31, 2021 – 7,050,000) were issued and outstanding 
under the equity compensation plan.

Convertible note payable 
 
On May 11, 2021, the Company entered into the Funding Agreement with Lind.  Each Convertible Security issuable under the 
Funding Agreement will have a two-year term from the date of issuance and will accrue simple interest rate obligation of 8.75% 
per annum.  The face value of the Convertible Security issued under the First Tranche was $4,112,500 to maturity. The Company 
agreed to pay Lind a 3% commitment fee of the amounts funded under the First Tranche and Second Tranche and due upon 
closing of each such tranche. 
 
Lind is entitled to convert the Convertible Securities into common shares in the capital of the Company over the term of the 
applicable Convertible Security, subject to certain limitations, at a conversion price equal to 85% of the five-day trailing volume-

weighted average price (“VWAP”) of the common shares prior to the date a notice of conversion is provided to the Company by 
Lind. The aggregate conversion amount shall not exceed 1/20th of the face value of the Convertible Security per month.  
 
In respect to the First Tranche, the Company issued 1,957,056 common share purchase warrants exercisable into 1,957,056 
common shares at an exercise price of CAD$1.0283 for a period of 48 months from the date of issuance. 
 
In addition, the Company has the option to buy-back 66.7% of the Convertible Securities in cash at any time with no penalty, 
subject to the option of Lind to convert up to one-third of the face value of the applicable Convertible Security into common shares 
at the time such option is exercised by the Company. 
 
The Convertible Security issued under the First Tranche has characteristics of a hybrid compound financial instrument with both 
an equity component and a financial liability component. 
 
On May 13, 2021, the closing date of the First Tranche, the monthly debt conversion amount of $205,625 was discounted using 
a risk adjusted discount rate and comparable bond option-adjusted spreads with ratings ranging from CCC to CC.  The common 
share purchase warrants were valued using a Black-Scholes model.  A liquidity discount was also incorporated to equate the debt, 
conversion options and warrants to the total gross proceeds received of $3,500,000.  Total transaction costs associated with the 
Convertible Security issued under the First Tranche were $340,982 of which $2,947 was allocated to common share purchase 
warrants. 
 
The Funding Agreement contains certain ongoing covenants of the Company typical of an agreement of its nature.  In the event 
of certain defaults by the Company under the Funding Agreement, Lind has the right, upon notice to the Company, to accelerate 
the conversion of the face value of any outstanding Convertible Security or demand repayment of such face value in cash and 
terminate the Funding Agreement.  No such notice has been delivered to the Company as at the date of these annual financial 
statements. A copy of the Funding Agreement is available on SEDAR at www.sedar.com. 
 
As of to date, Lind has, so far, converted an aggregate of $1,645,000 of the face value of the Convertible Security issued under 
the First Tranche into an aggregate of 6,764,798 common shares. As of July 31, 2022, the fair value of the Convertible Security 
was measured at its face value less all converted amounts, which approximated fair value. See Note 16 – Subsequent events for 
additional information related to additional conversions by Lind subsequent to July 31, 2022.

a certain antibody to target cancerous tissues of the lung.  In addition to the royalty payments, the Company is also required to 
make certain milestone payments:  $25,000 upon successful completion of Phase I clinical trials; $50,000 upon successful 
completion of Phase IIb clinical trials; $125,000 upon successful completion of Phase III clinical trials; and $200,000 upon receipt 
of market approval by regulatory authority. 
 
Pursuant to an agreement dated September 22, 2016 with the NRC, the Company is required to pay a royalty to the NRC of 3% 
of net sales, with a minimum royalty of $10,000 per annum generated from the use of a certain antibody to target cancerous 
tissues of the lung.  In addition to the royalty payments, the Company is also required to make certain milestone payments for the 
first licensed product:  $25,000 upon successful completion of Phase I clinical trials; $50,000 upon successful completion of Phase 
IIb clinical trials; $150,000 upon successful completion of Phase III clinical trials; $200,000 upon receipt of first regulatory approval 
by a regulatory authority; and $200,000 upon receipt of a second regulatory approval by a regulatory authority.  For the 
development of each subsequent licensed product: $200,000 upon receipt of first regulatory approval by a regulatory authority; 
and $200,000 upon receipt of a second regulatory approval by a regulatory authority.  As it relates to sub-licensing arrangements, 
the Company is required to pay the NRC 33% of any sub-licensing revenues received.  The anti-CEACAM6 single domain antibody 
2A3 is subject to this agreement.  As at July 31, 2022 the Company has accrued $nil (2021 – $nil). 
 
Pre-clinical Research Organizations 
 
In Fiscal 2022, the Company signed two pre-clinical collaboration agreements to research new and additional insights into the 
therapeutic response of L-DOS47; the first with the University of Tübingen for € 900.000 and the second with Moffitt Cancer Center 
and Research Inc. for US$479,630. 
 
Operating lease commitments 
The Company is committed to paying $13,000 under two month to month facility lease agreements with notice periods of no longer 
than two months. 
 
9. 
Capital risk management 
The Company’s main objectives when managing capital are to ensure sufficient liquidity to finance research and development 
activities, clinical trials, ongoing administrative costs, working capital and capital expenditures. The Company includes cash in the 
definition of capital.  The Company endeavours not to unnecessarily dilute shareholders when managing the liquidity of its capital 
structure. 
 
Since inception, the Company has financed its operations from public and private sales of equity, credit facilities, the exercise of 
warrants and stock options, and, to a lesser extent, from interest income from funds available for investment, government grants 
and investment tax credits.  Since the Company does not have net earnings from its operations, the Company’s long-term liquidity 
depends on its ability to access capital markets, which depends substantially on the success of the Company’s ongoing research 
and development programs, as well as capital market conditions and availability. 
 
The Company does not currently have enough cash reserves to fully fund its clinical trials nor does the Company have sufficient 
cash reserves to meet anticipated cash needs for working capital and capital expenditures through at least the next twelve months. 
On May 11, 2021, the Company entered into the Funding Agreement with Lind. The Funding Agreement is subject to certain 
ongoing covenants of the Company. See Note 7 – Convertible note payable and also Note 1 - Basis of presentation and going 
concern. 
 
10. Financial instruments and risk management 
Financial risk management 
The Company is exposed to a variety of financial risks by virtue of its activities: market risk (including currency and interest rate 
risk), credit risk and liquidity risk.  The overall risk management program focuses on the unpredictability of financial markets and 
seeks to minimize potential adverse effects on financial performance. 
 
Risk management (the identification and evaluation of financial risk) is carried out by the finance department, in close cooperation 
with management.  The finance department is charged with the responsibility of establishing controls and procedures to ensure 
that financial risks are mitigated in accordance with the approved policies. The Board has the overall responsibility for the oversight 
of these risks and reviews the Company’s policies on an ongoing basis to ensure that these risks are appropriately managed. 
 
Fair value of financial instruments 
Convertible note payable was recognized at fair value, both at the date of issuance on May 13, 2021 and subsequently at July 31, 
2021 and July 31, 2022. As of July 31, 2022, the fair value of the convertible note was measured at its face value less the converted 
amounts, which approximated fair value. See Note 7 – Convertible note payable for further information.

Market risk 
Market risk is the risk that changes in market prices, such as interest rates and foreign exchange rates, will affect the Company’s 
income or the value of its financial instruments. 
 
Currency risk 
The Company has international transactions and is exposed to foreign exchange risks from various currencies, primarily the Euro 
and U.S. dollar.  In addition, foreign exchange risks arise from purchase transactions, as well as recognized financial assets and 
liabilities denominated in foreign currencies. 
 
Balances in foreign currencies are as follows, as at:

Any fluctuation in the exchange rates of the foreign currencies listed above could have an impact on the Company’s results from 
operations; however, they would not impair or enhance the ability of the Company to pay its foreign-denominated expenses. 
 
Interest rate risk 
Interest rate risk is the risk that future cash flows of a financial instrument will fluctuate because of changes in interest rates, which 
are affected by market conditions.  The Company is exposed to interest rate risk arising from fluctuations in interest rates received 
on its cash and cash equivalents.  The Company is not subject to any debt related interest rate risk. 
 
The Company manages its interest rate risk by maximizing the interest income earned on excess funds while maintaining the 
liquidity necessary to conduct its operations on a day-to-day basis.  Any investment of excess funds is limited to risk-free financial 
instruments.  Fluctuations in the market rates of interest do not have a significant impact on the Company’s results of operations 
due to the relatively short-term maturity of any investments held by the Company at any given point in time and the low global 
interest rate environment.  The Company does not use derivative instruments to reduce its exposure to interest rate risk. 
 
Credit risk 
Credit risk is the risk of a financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its 
contractual obligation. 
 
The table below breaks down the various categories that make up the Company’s accounts receivable balances as at:

Liquidity risk 
Liquidity risk is the risk that the Company will not be able to meet its obligations as they come due.  Since inception, the Company 
has mainly relied on financing its operations from public and private sales of equity.  The Funding Agreement is subject to certain 
ongoing covenants of the Company that could affect the Company’s liquidity.  See Note 7 – Convertible note payable. 
 
The Company manages its liquidity risk by continuously monitoring forecasts and actual cash flow from operations and anticipated 
investing and financing activities. 
 
The Company’s cash reserves of $3,252,000 as at July 31, 2022 are insufficient to meet anticipated cash needs for working capital 
and capital expenditures through the next twelve months, nor are they sufficient to see the current research and development 
initiates through to completion.  To the extent that the Company does not believe it has sufficient liquidity to meet its current 
obligations, management considers securing additional funds primarily through equity arrangements to be of utmost importance.

The Company’s long-term liquidity depends on its ability to access the capital markets, which depends substantially on the success 
of the Company’s ongoing research and development programs, as well as economic conditions relating to the state of the capital 
markets generally.  Accessing the capital markets is particularly challenging for companies that operate in the biotechnology 
industry.

Scientific Research & Experimental Development expenditures (“SR&ED”) 
 
Under the Income Tax Act (Canada), certain expenditures are classified as SR&ED expenditures and are grouped into a pool for 
tax purposes. This expenditure pool can be carried forward indefinitely and deducted in full in any subsequent year. The SR&ED 
expenditure pool at July 31, 2022 is approximately $52,646,000 (2021 – $51,366,000). 
 
Investment tax credits 
 
The Company has also earned investment tax credits in Canada, on eligible SR&ED expenditures at July 31, 2022 of 
approximately $11,586,000 (2021 – $11,610,000), which can offset Canadian income taxes otherwise payable in future years up 
to 2042. Investment tax credits are accounted for as a reduction of the related expenditure for items of a current nature and a 
reduction of the related asset cost for items of a capital nature, provided that the Company has reasonable assurance that the tax 
credits will be realized. During the year, the Company received cash refundable investment tax credits related to prior years in the 
amount of $39,000 (2021 – $56,000). At July 31, 2022, cash refundable investment tax credits total $96,000 (2021 – $141,000). 
The research and development investment tax credits recorded are based on management’s estimates of amounts expected to 
be recovered and are subject to audit by the taxation authorities and, accordingly, these amounts may vary. Federal investment 
tax credits are non-refundable to the Company. Refundable investment tax credits reflect eligible SR&ED expenditures incurred 
in Ontario and Alberta. 
 
15. Deconsolidation of subsidiary held for sale 
The Company’s investment in HIO was classified as held for sale and was presented as discontinued operations at July 31, 2020. 
During fiscal 2021, at September 3, 2020 HIO completed a direct financing with an arm’s length party. As a result of such financing, 
the Company’s ownership in HIO was diluted down to 29.89% and, as a result, the Company determined that it had lost control of 
HIO during the three months ended July 31, 2021.  As the Company’s interest allows the Company to exert significant influence 
over HIO, the Company’s remaining interest is now accounted for as an interest in associate using the equity method. The 
Company’s remaining interest in HIO was recognized at its fair value as at September 3, 2020 based on the post financing 
valuation. The difference between the carrying value of the net assets of HIO and non-controlling interest and the value assigned 
to the shares of HIO of $2,231,000 was recognized as a gain on loss of control of subsidiary. 
 
The following information summarizes the accounting of the investment in HIO as at September 3, 2020, which is the date of
