ANNUAL REPORT 2021
With our LIGHT system, we have the ambition and 
the means to democratise proton therapy by treating 
patients not only at proximity to their family but also at a 
more affordable price for payers: proton therapy for all, 
not just the lucky ones. This is particularly beneficial for 
children, and we are proud to be working with partners 
who share this vision by going the extra mile for them.
1.
Story with a clear ethical purpose and true social impact
In the cancer market, an area with significant needs, we 
provide the latest technological advancement in proton 
therapy – a more targeted radiation therapy sparing up 
to 60% of healthy tissue. With the introduction of our 
LIGHT system, we expect to substantially increase the 
global availability of proton therapy, well above today’s 
global capacity of 87,000 patients a year. 
3.
Growing market opportunity with strong unmet 
need due to current costs
Our manufacturing processes are outsourced to leading 
manufacturers, further de-risking our business model, 
creating leaner operations, and laying out the foundations 
for cost optimisation, accelerated lead times and high-
volume production. We work with world-class partners 
and assemble our LIGHT systems in partnership with 
a UK-government body, the Science and Technology 
Facilities Council (STFC).
4.
Broad industrialisation ecosystem in place with 
high-quality partners
Our LIGHT system – created at the world-renowned physics 
and engineering institute, CERN – is designed to offer the 
most precise and fastest proton beam for cancer treatment 
whilst providing significant cost savings for payers. Due to its 
modularity and its ability to be installed into existing buildings, 
LIGHT is the first proton therapy equipment that can be 
leased, which is expected to dramatically accelerate the 
adoption curve, replicating the success of other breakthrough 
medical equipment such as MRI or CT scanners.
2.
Revolutionary CERN technology applied to address 
the current shortcomings in radiation therapy
The management team has significant experience in 
developing and launching radiation and proton-based 
equipment with extensive regulatory and commercial 
expertise. It is supported by experts and advisors whose 
reputation is unquestionable.
7.
Experienced management team with great track-
record and supported by high-profile industry 
experts
Our ability to dismantle and move our LIGHT system 
is the foundation of our business model. We can lease 
LIGHT to prospective customers, which reduces their 
upfront considerations. Furthermore our partnership 
with Kineo is an opportunity to fund our working capital 
requirements. The low treatment cost per patient and 
the ability of operators to service the debt due to the 
attractive financial profile of a proton therapy centre 
provide us with a further opportunity to take economic 
interest in the operations of the clinical facility whilst 
accelerating the pipeline ramp-up.
6.
Business model with complementary and strong 
sustainable revenue streams and a leasing model 
that is unique in proton therapy
With all the critical parts of LIGHT manufactured and 
delivered to our assembly site as well as our ISO13485 
certification, we are focused on the lower-risk parts of our 
project and on completing the Verification and Validation 
of LIGHT, a process aimed at ensuring the specification 
and user requirements are met. Therefore, we are 
uniquely positioned to fulfil a pipeline of interest already 
established in the UK, Europe, the US and across Asia 
and become the undisputed leader for proton therapy.
5.
Rigorous process-driven approach allowing the 
company to deliver on its plan
INVESTMENT

Business delivery 
34,000+
LIGHT and its supporting equipment has more 
than 34,000 items, of which roughly half are 
commercially off the shelf
The product complexity of LIGHT is a strong barrier to entry, given the 
need to document the design records (e.g. product requirements, product 
architecture, Bill of Materials, design reports, product risk analysis, etc.)
1/3 millimetre
The accurate evaluation of the beam energy 
requires measurement of time differences to 
picosecond precision; a picosecond being the 
time it takes light to travel one third of a millimetre
Protons can go as fast as 60% speed of light. Measuring the time protons 
travel between two spots of the machine is crucial to deliver the right 
treatment for patients
4,400
Almost 4,400 documents have been needed to 
support the certification of LIGHT through the 
quality management system
As an ISO13485-certified company, Advanced Oncotherapy must provide 
meaningful data evidence of effective quality controls. Data quality and availability 
are critical to the success of a quality management system framework to drive 
continuous improvement and preventative quality control activities
650 million
Protons travelling at a speed of 650 million km/
hour will damage a tumour located at a depth of 
32 cm
Accelerated protons get “energised”; the higher their energy and their speed, 
the deeper in the body the radiation damage will be made. There is a direct 
relationship between the energy of protons and their speed
200
Approx. 200 separate registered IP assets have 
been filed in more than 35 countries
Advanced Oncotherapy has a dedicated IP department to manage and grow 
its IP portfolio and to identify, assess and manage IP risks. The Company uses 
a range of approaches and strategies, depending on the type and content of 
property and its relation to the overall company strategy as defined by the Board
1,045
1,045 work applications were submitted in 2021 
from people willing to join Advanced Oncotherapy
The Company employs 174 employees as of end of 2021

The deposition of proton pulses can be varied and 
occur once every 5 milliseconds
This ultra-fast change makes LIGHT ideally suited for suited for the treatment 
of moving targets
3 billion 
The electromagnetic field inside the LIGHT 
accelerator changes sign 3 billion times per 
second
Protons are charged particles and can be accelerated if placed in an electro-
magnetic field. The strength and direction of the magnetic field is constantly 
changing so that the north pole becomes the south pole and vice-versa

ANNUAL REPORT 2021
Dear shareholders, 
Despite the unknowns brought by COVID-19 over the 
period, the Company’s objectives and purpose remained 
consistent with our vision of democratising proton therapy 
and guided our employees and partners to overcome 
moments that, at times, seemed insurmountable. We are 
now pleased and proud to say that Advanced Oncotherapy 
is on the verge of doing something that has never been 
done before – building a sustainable and value-enhancing 
platform to democratise access to proton therapy. We 
continue to be centre stage in the transformation of cancer 
care and the deployment of proton therapy, and what we 
do in this critical phase will define us for decades. 
From C to Sea
20 years ago, when family members had cancer, they 
would often call it the C word and it was hard to blame 
them: cancer was largely a death sentence for those who 
were unfortunate enough to get it. Few people can say 
their lives have not been touched by the disease, either 
personally or through friends and family. However, the 
combination of advances in cancer treatments, improved 
awareness and diagnosis, has changed the trajectory and 
prognosis of cancer.
Cancer mortality rates have plummeted over the past 
years, with four out of five of those diagnosed with 
childhood cancer set to survive for more than five years 
after diagnosis. While this is great news, much more 
remains to be done. An estimated ten million people die 
from cancer each year, and about 75% of cancer survivors 
have one or more health problems, often as a side-effect of 
the treatments they received, ranging from heart failure due 
to chemotherapy, to secondary malignancies as a result 
of radiotherapy. Chronic problems are also associated 
with surgeries to remove cancers. These methods have 
influenced an ‘innovation’ mindset that is focused on 
improving clinical outcomes and patients’ quality of life. This 
is best exemplified by the development of more targeted 
cancer modalities, arguably the most important paradigm 
treatment shift in cancer care over the last decade.
Proton therapy – as an effective proven radiation therapy 
with limited long-term side effects due to its high precision 
– has a key role to play in transforming cancer treatment. 
Yet, with only 114 proton therapy centres currently 
across the globe, only circa 87,000 cancer patients can 
be treated in one year at a cost which is often out of the 
reach of individual patients and is clearly unsustainable for 
healthcare systems. This situation is unsatisfactory and, as 
such, access to proton therapy needs to be democratised. 
We believe this can be achieved through our ‘blue ocean’ 
strategy which relies on the following ‘5S’ principles:

Executing our global strategy
In a highly regulated industry, we must continue to 
demonstrate our ability to adapt to our environment 
and remain agile by accelerating the speed at which 
we execute our strategy to deliver improved returns. 
In 2021, the executive team made significant progress 
in overseeing the assembly of the LIGHT system at 
our assembly and integration site located in Daresbury, 
UK, as well as laying out the groundwork for a potential 
successful market approval.
Execution of our ‘5S’ strategy has also required a disciplined 
approach to how we invest in our assets. Over the last 
two years, we have made significant investments in our 
infrastructure. The trajectory of investment across our 
organisation is pivoting towards further cost optimisation 
for future machines and faster delivery times. The Board 
supports this approach and continues to encourage the 
executive team to shift their attention to rapid execution, with 
the key focus areas being the long-term financial benefits 
of making Advanced Oncotherapy the undisputed industry 
leader and innovator in the proton therapy field. This is crucial 
if we are to benefit from the versatility of the LIGHT platform 
and knowledge uniquely nurtured within our organisation as 
we pursue our various multi-year strategic goals.
In 2021, our execution plan and resilience as an 
organisation continued to be tested by COVID-19.

functioning, fluctuating demand in certain areas, workplace 
operations – we continued to be focused on our LIGHT 
project. We instigated supply chain initiatives to identify and 
use alternative components and suppliers whilst complying 
to ISO standards and medical device requirements. We 
contracted with key suppliers to recruit additional installation 
and testing expertise and capacity. Most importantly, we 
kept our sights on our long-term objectives and our dynamic 
vision for the future of health. This confirmed the fortitude 
of our employees and dedication to the values that guide 
our behaviour every day and help us to build a business 
of the future. We are inspired by the abundant accounts of 
the extraordinary care, compassion and commitment of our 
employees as well as the strength of our organisation which 
has been resourceful and adaptable, able to anticipate, 
improvise, and draw on deep reserves of experience, 
relationships, and know-how.
The LIGHT system: a machine that will 
revolutionise cancer treatment
There is currently a significant unmet medical need in the 
treatment of cancer, and we believe the LIGHT system 
can play a key role in revolutionising cancer therapy. The 
modularity and movability of the LIGHT system allow us to 
lease machines to healthcare providers – a new business 
model in the proton therapy market – uniquely positioning 
the Company in the market and providing us the opportunity 
to play a key role in revolutionising proton therapy.
The accelerator, currently under final assembly, is driven 
by four inductive output tubes (IOTs) operating at 750 MHz, 
which generate the relevant power for the radiofrequency 
quadrupole (RFQ), and 13 klystrons operating at 3 GHz, 
which provide high radio-frequency power to the machine 
to accelerate the proton beam. The accelerator is cooled, 
kept under vacuum, and monitored by beam diagnostics 
and the Company’s time-of-flight energy measurement 
algorithm. Our proprietary LIGHT Accelerator Control 
System integrates more than 300 separate devices and 
is driven from a control room where operators accelerate 
and steer the proton beam. Protons go through a gallery of 
accelerators moving as a 200Hz pulsed beam through the 
RFQ, the side-couple drift tube linacs (SCDTLs) and then 
through the 15 coupled cavity linacs (CCLs) accelerating 
up to a maximum energy of 230 MeV, the energy required 
to treat deep-seated tumours at a depth of 32cm. Patient 
treatment will take place in the treatment room which is 
located at the end of the accelerator where a state-of- 
the-art robot chair, with CT scanner and X-Ray panels for 
accurate patient positioning, has been installed.
During the period, the Company has continued to make 
significant progress with the commissioning of the LIGHT 
system. The machine installed at Daresbury has been 
successfully optimised to deliver a proton beam with 
a beam size smaller than 1 mm and a beam current of 
about 50 μA, equivalent to 500 million protons per pulse. 
As a result, the Company has made good progress in 
preparing data for the US Food and Drug Administration 
(FDA) regarding the stability, intensity and spot size of 
the proton beam. These new data sets demonstrate 
that the measurements of the quality of the beam match 
those from computer simulations. The Company can now 
proceed to finalise the integration of the remaining high 
energy accelerating modules of the LIGHT machine and 
further optimise the proton beam.
We have continued to work with our clinical collaborator 
(the University Hospitals Birmingham NHS Foundation 
Trust) and Clarivate, a global analytics company, to define 
the clinical protocol for treating the first patients. These 
discussions have been held in close coordination with 
the FDA, the UK Medicines and Healthcare products 
Regulatory Agency (MHRA) and the European Notified 
Body, which we consult with on a regular basis. As a result 
of these discussions, the Company has been requested to 
provide new measurement data to confirm that the beam 
performance is maintained within the required tolerances 
for the clinical use both in terms of energy (i.e. depth in the 
body) and intensity (i.e. number of protons per second). 
Although these measurements have not been conducted 
with the final configuration for 230MeV, they indicate that the 
beam stability is not a cause for concern in the planned final 
configuration, a key step which is expected to de-risk the 
overall certification process. This request originates from the 
fact that the key LIGHT components are now assembled in 
situ at Daresbury and the underlying parameters have been 
optimised in recent months as the Company performs the 
verification and validation activities, a key step in ensuring 
product certification.
Commercial momentum 
Over the past year, we continued to build commercial 
momentum around the LIGHT system. During the period, 
we signed a lessor financing partnership with Kineo 
Finance (formerly known as DiaMedCare). Under the 
terms of the partnership agreement, Kineo Finance will 
acquire LIGHT systems from the Company and lease 
them to customers that are commissioning the LIGHT 
system for oncology treatments. As such, we will be able 
to offer customers easier access to the LIGHT system 
through a flexible financing solution that reduces the need 
for large initial upfront payments from customers. 
During the period, we also signed a letter of intent with 
Saba Partners SA for the proposed purchase of a three-
treatment room LIGHT system in Switzerland. The 
Company is working to obtain the applicable CE marking 
clearances and is working with Saba Partners to put in place 
a binding agreement and finalise the legal documentation. 
These agreements build on the commercial momentum 
for the LIGHT system from our earlier agreements with the 
London Clinic, the Mediterranean Hospital in Limassol, 
Cyprus, and University Hospital Birmingham NHS 
Foundation Trust (UHB).

ANNUAL REPORT 2021
Our corporate strategy has five distinct focus areas. It is built on our purpose and our ambition to be a sustainable 
business. We aim to: 
•	
solve customers’ needs;
•	
support customers through long-term servicing contracts;
•	
scale the infrastructure to meet the demand;
•	
share vision with all stakeholders through long-term interest alignment;
•	
sustain the Company’s competitive advantages.

Accessing a larger segment of the radiation therapy market… 
We intend to disrupt the radiation therapy market by selling to a broad range of customers that have yet to make an investment 
in proton therapy due to the challenges associated with conventional proton therapy.
…by providing a solution, not just a product …
We intend to be a patient-centric solutions leader. Our commitment is to solve problems through a turn-key solution. We focus 
on what matters for all stakeholders in our ecosystem: integrated solution including the accelerator, the imaging system, the 
software package; medically superior solution to existing systems; easier to install and fit; more accessible; value-enhancing for 
customers and the Company’s shareholders.
… and enhancing awareness of the LIGHT benefits    
We intend to attract new customers by educating the market about our leading and differentiated system and its unique capabilities.
SOLVE customers’ needs
Providing long-term servicing contract to ensure reliability of the operations; …
We intend to support our customers – beyond the installation of a LIGHT system – by being the single-point responsibility for 
long-term servicing and maintenance operations. The complexity of proton therapy systems demands that they are serviced by 
a single source that has the knowledge and the ability to do so, so that customers can reliably operate LIGHT.
… a key strategic pillar that has many other advantages
We intend to leverage our servicing strategy; this is expected to result in future business development opportunities and generate 
steady income streams.
SUPPORT customers through long-term servicing contracts
Promoting a “skin in the game” culture with key stakeholders
We intend to build partnerships through a clear long-term interest alignment. Our approach is therefore based on removing the 
silos arising from the conventional supplier/customer relationship. To do so, we are focused on implementing new models as 
exemplified by our partnership with Cosylab, a strategic supplier focused on software development and incentivised through 
payment in Company’s shares.
Working closely with customers
We intend to expand the market opportunity through a uniquely designed business model built upon a joint risk/reward sharing 
policy as evidenced by the profit-sharing arrangements agreed with customers. This brings many benefits such as the opportunity 
to gain valuable insights about the customers’ operations and generate more recurring revenue streams.
SHARE vision with all stakeholders through long-term interest alignment
Leveraging our proprietary LIGHT platform
We intend to leverage our proprietary LIGHT platform by continuously enhancing our clinical capabilities with new and improved 
product functionalities and technologies, including the development of FLASH, the deployment of mini-beams and the synergistic 
combination of proton therapy with immunotherapies. The latter leverages the unique features of LIGHT, including its high 
precision and ultra-fast delivery, and offers the opportunity to treat cancer types which can not be treated today. Further routes 
for innovation relate to beam delivery, patient imaging, positioning and motion management and streamlined clinical workflow.
Investing in talent
We intend to attract and retain top talent as the industry remains characterised by scarcity and competition for skills and 
capabilities. This is key to sustain our competitive edge and nurture our culture.
Making a positive impact on society and environment
We intend to integrate sustainability in a systematic way throughout the entire value chain and decision-making process to truly 
influence the Company directions and build resilience.     
SUSTAIN the Company’s competitive advantages
Building the foundation for delivering a fast-growing pipeline…
We intend to scale our assembly infrastructure and deepen the relationship with our partners and suppliers to increase the 
number of LIGHT systems which can be installed in any given year. 
… and further optimising costs and delivery times
We intend to further optimise costs and reduce lead times by implementing identified initiatives and leveraging our operational set-up. 
SCALE the infrastructure to meet the demand

CANCER, SET TO BECOME THE NUMBER-ONE 
CAUSE OF DEATH IN MOST 
SOCIETIES
Cancer, the abnormal proliferation of cells which is 
capable of both invading surrounding normal tissue 
and spreading throughout the body
Cancer is a broad term often used to describe a large group 
of diseases defined by uncontrolled cell growth and division. 
These cancer cells do not die. They invade normal tissues 
and organs, and eventually spread throughout the body. Their 
generalised loss of growth control is the net result of accumulated 
abnormalities in multiple cell regulatory systems and is reflected 
in several aspects of cell behaviour that distinguish cancer cells 
from their normal counterparts:
•	
Cancer cells do not stop growing and dividing. Unlike 
normal cells, cancer cells do not stop growing and dividing 
when there are enough of them. So, the cells keep doubling, 
forming a lump (tumour) that grows. A tumour forms, made 
up of billions of copies of the original cancerous cell. Cancers 
of blood cells (leukaemia) do not form tumours, but they 
make many abnormal blood cells that build up in the blood;
•	
Cancer cells have abnormal differentiation. They do not 
mature normally; therefore, they are not able to carry out 
their functions; 
•	
Cancer cells ignore signals from other cells. Cells 
send chemical signals to each other all the time. Normal 
cells obey signals that tell them when they have reached 
their limit and will cause damage if they grow any further. 
But something in cancer cells stops the normal signalling 
system from working; 
•	
Cancer cells invade nearby tissues. Normal cells respond 
to signals from other cells which tell them they have reached 
a boundary. Cancer cells do not respond to these signals and 
extend into nearby tissues often with finger-like projections. 
This is one reason why it is difficult at times to surgically 
remove a tumour. The word cancer, in fact, is derived from 
the Greek word carcinos for crab, referring to these claw-like 
extensions into neighbouring tissues; 
•	
Cancer cells can spread to other regions of the body 
via the circulatory or lymphatic systems (metastasis). 
Unlike normal cells which make substances called adhesion 
molecules that cause them to stick to nearby cells, cancer 
cells can break free and float to other regions of the body. 
Only malignant tumours are properly referred to as cancers, 
and it is their ability to invade and metastasise that makes 
cancer so dangerous. Whereas benign tumours – which 
remain confined to their original location, neither invading 
surrounding normal tissue nor spreading to distant body 
sites – can usually be removed surgically, the spread of 
malignant tumours to distant body sites frequently makes 
them resistant to such localised treatment;
•	
Cancer cells do not repair themselves or die. Normal cells 
can repair themselves if their genes become damaged. This 
is known as DNA repair. Cells self-destruct if the damage is 
too bad in a process called apoptosis. In cancer cells, the 
molecules that decide whether a cell should repair itself are 
faulty;
•	
Cancer cells have specific tumour markers. They can 
express proteins, called antigens, on the cell surface, which 
makes them different from normal, healthy cells. 
Cancer is a devastating disease that 
takes an enormous emotional toll. 
Not only on the patient, but on the 
patient's loved ones, as well. It is a 
battle that humans have been fighting 
for centuries. And while we have made 
some advancements, we still have not 
beaten it. Two out of five people in the 
US will develop cancer in their lifetime. 
Of those, 90 percent will succumb to the 
disease due to metastases.

Cancer can affect people of any age but occurs more often in older people, most likely from cumulative exposure to 
carcinogens, agents that are known to increase cancer risk. Cancer comes from our own cells; however, our chances 
of being affected by the disease can be linked to factors that come from both within and outside of our bodies.
Every time cells divide; they make a 
copy of the genetic code contained 
within them. This copying process is 
not always perfect and occasionally 
results in typos, or errors in the DNA, 
which are called mutations. Cells 
have ways to detect and fix these 
mistakes, but they do not always 
work. If a cell develops a mutation, it 
may start to act differently to a normal 
cell.

Compared to cardiovascular diseases, neurological/mental disorders and diabetes, cancer is associated with the 
highest disease burden (20.8% of DALYs across all diseases) but the second-lowest healthcare expenditure levels 
(4.8% of total healthcare expenditure) among the studied major chronic diseases. 
Despite advances, the number of cancer patients is set to climb over the coming decades
Cancer is not always a death sentence. In many countries more people are surviving cancer than ever before. In fact, there 
are now 28 million people living with or beyond cancer worldwide, a number that has increased nearly five-fold since the 
70’s. Cancer’s death rate has been reduced by 27 percent over the past 25 years, giving cancer patients increased hope for 
survival. This is largely due to the emergence of new treatments and technologies as well as earlier detection.
Yet, this should not obscure three important challenges. 
•	
GLOBOCAN 
2020 
made 
a 
staggering 
prediction: 
with 
an 
aging population, it expects the 
number of new cancer cases to rise 
markedly, reaching an astounding 
28 million cases annually by 2040, 
a 47 percent rise from 2020. The 
U.S. Cancer Society estimates 
that almost 40 percent of men 
and women will be diagnosed with 
cancer during their lifetime;
•	
Despite the upward trajectory of 
cancer survival rates, it remains 
chillingly apparent that there is still 
a huge, unmet need in the fight 
against cancer. Several forms 
of cancer are almost completely 
unresponsive to treatments that 
have been developed over the last 
40 years: for example, the five-
year survival rate from pancreatic 
cancer 
remains 
barely 
above 
five percent at five years after 
diagnosis. Brain tumours probably 
cause more “years of life lost” than 
any other sub-type of disease, and 
the most aggressive forms of this 
disorder offer some of the greatest 
challenges 
within 
medicine. 
Despite the disease burden, the 
level of investment and healthcare 
expenditures in cancer remains 
below major chronic diseases.
•	
For patients and their families, 
the costs associated with direct 
cancer care are staggering. In 
the UK, young people (under 35) 
and people approaching pension 
age (55-64) are most likely to see 
a decline in their financial health 
because of cancer, at 67 and 60 
percent 
respectively. 
Drawing 
on this, the total economic cost 
of cancer to the UK economy in 
terms of lost wages and benefits 
is estimated at approximately £1.4 
billion a year or £7.6 billion a year 
when considering mortality.

Cancer is complex, so approaches to its 
treatment must match that complexity
Once a cancer has formed, the cells do not remain the 
same, but rather continued mutations may occur. This, 
in fact, is why resistance develops to chemotherapy and 
targeted therapy drugs in time. The cancer cell develops 
a mutation that allows it to bypass the damaging effects 
of these treatments. That cancer cells change is very 
important in treatment. For example, a breast cancer that 
is oestrogen-receptor positive may be oestrogen-receptor 
negative when it recurs or spreads. It also helps explain 
why cancer cells in different parts of a tumour may be 
different. This is referred to as "heterogenicity" and is 
important in diagnosis and treatment as well.
Consequently, clinicians must have an array of treatment 
options for their cancer patients. 
•	
Surgery is aimed at removing tissue from the body. 
It remains a mainstay in the cure and control of most 
solid cancers; it is often the first treatment offered to 
patients. Surgery can have different purposes: cure; 
prevent; diagnose; uncover the extent of cancer 
(staging surgery); remove a portion, though not all, 
of a cancerous tumour (debulking surgery), relieve 
discomfort and pain, etc. Surgery is not used for some 
types of cancer of the blood system (leukaemia), or 
lymphatic system (lymphoma), because cancer cells 
might spread throughout the body. Surgery may also 
not be possible because of its location near delicate 
tissues or blood vessels.
•	
Chemotherapy is a drug treatment that uses powerful 
chemicals to kill fast-growing cells. Chemotherapeutic 
agents are cytotoxic that harm malignant as well as 
healthy cells in cancer patients. There are different 
drug types of chemotherapy drugs available which 
includes alkylating agents, plant alkaloids, antitumour 
antibiotics, 
antimetabolites 
and 
topoisomerase 
inhibitors. To improve patients’ quality of life, 
chemotherapy is often used as an adjuvant to other 
therapeutic modalities such as radiation therapy and 
surgery. 
•	
Targeted therapy is a cancer treatment that uses 
drugs to target specific genes and proteins that are 
involved in the growth and survival of cancer cells. 
Targeted therapy can affect the tissue environment 
that helps cancer grow and survive or it can target 
cells related to cancer growth, like blood vessel cells. 
•	
Immunotherapy is a type of cancer treatment that 
helps the immune system fight cancer. The immune 
system helps fight infections and other diseases. It is 
made up of white blood cells and organs and tissues 
of the lymph system. There are different categories of 
immunotherapy which includes immune checkpoint 
inhibitors, T-cell transfer therapy and monoclonal 
antibodies. Immunotherapy is one of the most recent 
advancements in cancer therapy that has improved 
the effectiveness of overall cancer therapy. This 
treatment option is based on a commonly accepted 
hypothesis that the immune system is an effective 
tool for combating various diseases. Researchers 
have developed certain approaches for the use 
of immunotherapeutics in cancer treatment that 
include stimulating the immune system externally 
so that it would act forcefully or destroy the tumours 
with tumour specific proteins. Immunotherapy, most 
often, is used in combination with surgery, radiation, 
or chemotherapy to augment the therapeutic 
effectiveness of the cancer treatment.
•	
Hormonal therapy is a treatment that adds, blocks 
or removes hormones to slow or stop the growth of 
cancer cells that need hormones to grow.
•	
Radiation therapy is an important technique for 
shrinking and killing tumours. High energy waves 
are targeted at the cancerous cells. The waves stop 
certain internal functions of the cell that are involved 
in cell division, so the cells eventually die.

Radiotherapy, a well-proven technology with a 
longstanding history of treating cancer patients
 
Today, radiotherapy is provided to up to two-thirds of cancer 
patients, either on its own or alongside other forms of therapy. 
It has won a place as a mainstay of modern cancer treatment, 
coming a long way since Wilhelm Conrad Roentgen, a 
German physics professor, presented in 1896 a lecture 
entitled “Concerning a New Kind of Ray.” Roentgen called 
it the “X-rays”, with “x” being the algebraic symbol for an 
unknown quantity; he received the first Nobel Prize awarded in 
physics in 1901. Three years after Roentgen’s breakthrough, 
the physicist Marie Curie discovered the chemical element 
radium, another source of radiation. Scientists in the US and 
Europe then began studying the use of radium and X-rays 
to treat cancer. They also discovered that daily doses of 
radiation over several weeks greatly improved the patient’s 
chance for a cure. Soon, it became clear that radiation was 
a highly effective tool against cancer, but it was also harmful 
for patients and clinicians. Early radiologists developed 
leukaemia after testing their machines on their own arms: 
they were estimating the daily fraction of radiation by looking 
for a dose that would produce on their skins a pink reaction 
(erythema) which looked like sunburn.
Further advances were made in the first half of the 20th 
century following the work of the English physicist Hal Gray 
– after whom the radiation unit of measurement (the Gray) 
is named – on how cells respond to radiation. High-energy 
X-rays were also introduced, providing improved treatment of 
deep-seated tumours. In the 1990s, the advent of computers, 
CT scanners and the use of CT for radiation planning were 
dramatic breakthroughs in radiation treatment because they 
allowed the ability to design radiation beams to directly target 
the tumour and for the first time accurately calculate doses 
received by nearby healthy organs. Conformal Radiation 
Therapy ("CRT") – which uses CT images and special 
computers to map the location of a cancer very precisely 
in three dimensions – was deployed in hospitals. Although 
3D-CRT was a significant improvement over conventional 
2D planning, it had limitations: 3D-CRT beams deposit a 
uniform strength of radiation (intensity) across specific field(s), 
thus they cannot conform to concave structures. Concave 
conformality requires the ability to modulate radiation beam 
intensity across a field. With the development of Intensity-
Modulated Radiation Therapy ("IMRT"), it became possible 
to adjust the intensity, giving more control in decreasing the 
radiation reaching normal tissue while delivering a high dose 
to the cancer. 
Since then, new techniques have been introduced such as 
stereotactic radiosurgery and stereotactic radiation therapy 
which are used to deliver a large, precise radiation dose to 
a small tumour. The term surgery may be confusing because 
no cutting is done. The most common site treated with this 
radiation technique is the brain. A significant attention is also 
currently placed on the development of chemical modifiers 
or radiosensitisers which are substances that make cancer 
more sensitive to radiation. The goal of research is to develop 
agents that will make the tumour more sensitive without 
affecting normal tissues. Researchers are also looking for 
substances that may help protect normal cells from radiation.
However, there is a general consensus that the development 
of X-rays techniques has now reached a limit, which is due to 
the physics of photons. 
X-rays were discovered by accident. Roentgen had 
been doing experiments with cathode rays—streams 
of electrons in vacuum tubes. He had prepared a 
glass cathode ray tube completely covered with black 
cardboard, and noticed that even though the cardboard 
completely covered the tube, a glow still appeared on 
a fluorescent screen several feet away. After Roentgen 
prepared one of the earliest X-ray images of the bones 
in the hand of his wife, she remarked: “Now I have seen 
my death!”

Photons are subatomic particles which are 
always in motion, travelling at the speed of 
light in empty space. The energy of a photon 
depends on radiation frequency; there are 
photons of all energies from high-energy 
gamma- and X-rays, through visible light, to 
low-energy infrared and radio waves. Photons 
have no electric charge and zero mass
Einstein proved that light is a 
flow of photons, the energy of the 
light being directly related to the 
wavelength. Shorter wavelengths 
are higher energy. Therefore, 
X-rays and ultraviolet can be 
harmful, unlike radio wave and 
infrared light. In the case of an 
X-rays, its wavelength is 0.01 to 
10 nanometres. As a comparison, 
fingernails grow about one 
nanometer per second. Photons 
possess enough energy (100 eV 
to 100 keV) to disrupt molecular 
bonds and ionise atoms making it, 
by definition, ionising radiation.
X-rays, using the basic unit of all light (photons) to damage 
cancer cells
Approximately 98% of radiation is currently delivered through X-rays. 
X-rays are packets of electromagnetic energy – also called photons – that 
originate from the electron cloud of an atom. X-rays photons are created 
through an energy change in electrons, which are excited, causing the 
excess energy to be released. This change of energy is generated in a 
vacuum-sealed X-ray tube, using a high voltage potential to accelerate 
electrons from a cathode to a spinning anode, often comprised of tungsten. 
Radiation therapy works by exposing clusters of cancer cells to a dose 
of high energy radiation sufficient to damage their genetic information, 
the DNA which contains the information used to control cell growth and 
division. When cancer cells are exposed to radiation, they cannot divide 
successfully and die. 
Radiation therapy damages both healthy cells and cancer cells in the 
treatment area. Therefore, the clinician’s goal is to target radiation delivery 
to the tumour as precisely as possible to maximise the radiation dose 
delivered to cancerous tissue and minimise the exposure of healthy tissue. 
Still, radiation affects cancer cells more than normal cells. Cancer cells 
reproduce faster than normal cells and lack the controls found in normal 
cells. Because of this, it is harder for cancer cells to repair the damage done 
by radiation. So, cancer cells are more easily destroyed by radiation, while 
healthy cells are better able to repair themselves and survive the treatment.
Radiation can be used alone or in addition with other treatments to cure or 
stabilise cancer. Like other therapies, the choice to use radiation to treat a 
particular cancer depends on a wide range of factors. These include, but 
are not limited to, the type of cancer, the physical state of the patient, the 
stage of the cancer, and the location of the tumour.

Allowing healthy cells to recover between treatments through fractionation
Radiation therapy is delivered in small doses called fractions, which are measured in centigray or cGy. These fractions are given 
each day, most often Monday to Friday, for a period of five to seven weeks. This fractionation seeks to maximise the destruction of 
malignant cells while minimising damage to healthy tissues: splitting the total radiation dose allows healthy cells an opportunity to 
repair this sublethal damage between fractions. Meanwhile, malignant with impaired DNA repair pathways are less able to recover 
from radiation damage to their DNA. The effect of fractionation is further supported by two fundamental cellular mechanisms:
•	
The radiosensitivity of cells depends on their stage in the cell cycle. Cells are most sensitive to radiation in the M and late 
G2 phase of their cycle and most resistant in the late S phase. Since a group of malignant cells are at various points in 
their cell cycle, delivering the entire dose of radiation in a single fraction is ineffective against a proportion of the tumour 
cells. Dividing the total dose of radiation into multiple fractions maximises the probability of irradiating cells when they are 
in the most radiosensitive period of their cell cycle; and
•	
The concentration of oxygen in the body ranges from 14% in the alveoli to 5% in peripheral tissues, a proportion that 
may be significantly lower in tumours. Cancer cells with a low oxygen concentration are less susceptible to the effect 
of radiation. Therefore, fractionation allows cells which are closer to sources of oxygen to be killed first whilst the other 
malignant cells will become more sensitive to subsequent doses of radiation once they receive a greater oxygen supply.

Fundamental facts around protons and their relevance in 
a medical setting
The physical property of protons, the key for a superior medical 
outcome in cancer treatment 
Protons are particles with a positive electric charge which are, along 
with neutrons, in the nucleus of an atom. The rest of the atom consists 
of electrons with a negative electric charge that orbit the nucleus. 
Therefore, the atoms of elements are neutral, all the positive charges 
cancelling out all the negative charges. Atoms differ from one another 
in the number of protons, neutrons and electrons they contain. Atoms 
of hydrogen have a single proton in their center and a single electron 
whilst helium atoms, on the other hand, have two protons and two 
electrons. Protons used in proton therapy are typically extracted from 
hydrogen through electrolysis, a process aimed at separating the 
proton and the electron.
When protons are accelerated in a particle accelerator, they acquire an 
energy: the more they get accelerated, the more energy they acquire, 
the higher their speed and the deepest in the body they stop. Once 
protons are accelerated and hence, they are “energised”, then they 
lose their gained energy based on the Bragg peak curve: the amount 
of energy lost by protons is inversely proportional to the square of their 
velocity; this explains why protons release their maximum energy – 
which damages the DNA of cancer cells – just before they come to a complete stop. This point corresponds to the Bragg peak; this 
is the spot where the maximum damage is made to a tumour. Therefore, and due to this physical property, proton beam radiation 
can deliver more radiation to the cancer while reducing damage to nearby normal tissues. This is in stark contrast with X-rays 
photons which gradually lose their energy, hence damaging the tumour but also the healthy tissues before and after the target. This 
is further compounded by the fact that protons are significantly heavier than photons, hence the rays of proton therapy scatter less 
easily than photons X-rays, thereby preventing radiation risk to healthy tissues beyond the cancerous cells.
Proton therapy’s greatest 
advantage over conventional 
radiation therapy is its accuracy 
and its ability to powerfully 
treat cancerous tissues while 
avoiding healthy ones. 
Conventional X-rays are made 
of photons that pass through the 
body and deposit considerable 
energy before and after the 
tumour. Proton therapy offers 
great promise in the treatment of 
a wide variety of cancers owing 
to the sharp drop-off in radiation 
dose at a defined point, known 
as the Bragg peak, beyond 
which there is no appreciable 
dose. Therefore, it deposits less 
energy on its way to the tumour 
and does not affect tissues 
beyond it. This confines the 
radiation dose to the tumour and 
decreases the risk of injury to 
surrounding healthy tissues.

extra dose in the tumour. 
X-rays (Photons) 
Photon dose distributions as a function of 
depth show a maximum dose close to the 
entrance after a short build-up and then an 
exponentially decreasing energy deposition 
with increasing depth in tissue. 
Protons are positively charged and therefore 
attract negative charges. When a proton – as 
a positively charged particle – is launched near 
a molecule such as DNA, negatively charged 
regions of the molecule will be attracted to the 
proton, thus interfering with that molecule's 
normal orientation and function. The result of this 
process is ultimately the death of cancer cells.

Putting things in perspective: The energy of a particle is 
measured in electronvolts. One electronvolt is the energy 
gained by an electron that accelerates through a one-volt 
electrical across a distance of 1 metre. As they race around 
the Large Hadron Collider ("LHC"), the protons acquire 
an energy of 6.5 million million electronvolts, known 
as 6.5 tera-electronvolts or TeV. It is the highest energy 
reached by an accelerator, but in everyday terms, this is 
a ridiculously tiny energy; roughly the energy of a safety 
pin dropped from a height of just two centimetres. But an 
accelerator concentrates that energy at the infinitesimal 
scale – protons have radius of under a millionth of a 
billionth of a metre – to obtain very high concentrations of 
energy close to those that existed just after the Big Bang.
Advanced Oncotherapy’s LIGHT accelerator is designed 
to accelerate protons to 230 million electronvolts or 230 
Mega electronvolts ("MeV"); this is equivalent to 0.004% 
of the energy of protons accelerated in the LHC.

The advantages of proton therapy over conventional X-rays
With a success rate of up to 96%, proton therapy is unique in its accuracy 
and in its heightened ability to avoid damage to healthy cells or tissues 
during treatment. This results in a wide range of benefits for patients. 
More specifically:
•	
Proton therapy is ideally suited for treating hard-to-treat tumours such 
as tumours located near critical organs (e.g., brain, head, and neck, 
etc.) as well as children and young adults who are more susceptible 
to injury from standard X-rays radiation because their tissues and 
organs are growing more rapidly. This is due to the higher precision 
of proton therapy and the reduced scattering effect of protons. It is 
estimated that on average proton therapy will damage 60% less 
healthy tissues when compared to conventional radiation therapy;
•	
Proton therapy is a highly preferred radiation treatment option for 
the elderly and weakened people due to its attractive safety and 
tolerability profile;
•	
By targeting the tumour precisely, side effects can be reduced. 
Patients experience fewer side effects with proton therapy because 
damage to healthy tissue and surrounding organs can be limited. 
Studies have shown that proton therapy can significantly decrease 
the estimated risk of developing secondary malignancies;
•	
Radiation oncologists have more flexibility in the way they can treat 
patients. Due to fewer complications and side effects, physicians 
can deliver higher curative doses of radiation to the tumour. They 
can also more safely escalate the level of radiation to the tumour, 
if needed;
•	
Proton therapy may be used for early cancers that in theory should 
be operable, but are deemed inoperable due to their location near 
vital structures or when a patient is not a good candidate for surgery;
•	
Generally, proton therapy does not require hospitalisation and 
allows for daily treatment on an outpatient basis. Depending on the 
specific treatment plan, patients typically receive daily treatments for 
several weeks. Treatments vary according to tumour type, location, 
size, and the patient’s overall health and diagnosis;
•	
Because proton therapy is a more accurate method for delivering 
radiation to the site of a tumour, it is the only radiation treatment 
available that can treat recurrent tumours that have previously been 
treated with radiation. Lung cancer dominates this group of patients, 
although the same logic applies to other groups;
•	
Proton therapy can be used in conjunction with other cancer 
treatment modalities;
•	
Proton therapy is well-proven and has been used around the world 
for decades. It was pioneered in the United States more than 50 
years ago. By 2020, it had been used to treat more than 250,000 
patients. Over the last few years, proton therapy has emerged as 
the most effective treatment method for a variety of cancers. This 
is supported by a growing body of clinical evidence showing that 
proton therapy is effective while reducing side- effects for many 
cancers.

Retrospective and prospective studies have shown promising outcomes with proton therapy for children and young adults with 
cancers, and for sites such as tumours near skull base and spine, CNS tumours, head and neck, oesophageal, hepatocellular, 
and thoracic cancers.
The past few years have seen a noticeable spurt in prospective and randomised studies, including trials for several sites such 
as breast, prostate, lung, head and neck, hepatocellular, oesophageal and brain cancers. This is expected to result in a wider 
scope of clinical application and acceptance amongst clinicians.

Experiencing proton therapy, from the patient’s 
point of view
Proton therapy is delivered in brief outpatient sessions 
which last on average between 15 to 30 minutes, although 
the delivery of the proton beam only takes a few minutes. 
Most of the time spent relates to the patient positioning and 
adjustments to the equipment settings. During each visit, 
the patient receives a “fraction” of the entire radiation dose 
that must be delivered over the entire treatment cycle. 
Typically, a patient receives 30 fractions over a period of 
45 days. Proton therapy treatment is painless. Children 
under 6-year-old might need to get general anaesthesia to 
keep them completely still during the treatment.
Several preparation steps are needed before the patient 
begins proton therapy. The first step is a procedure 
referred to as "simulation," in which the patient is fitted 
into a specialised immobilisation device to ensure the 
person maintains the same exact position for every visit. 
Sometimes, placing a metallic marker – a fiducial marker – in 
or around the tumour is needed to help guide the treatment. 
If necessary, these procedures are usually performed a few 
days before the simulation. Images of the tumour are also 
taken, using various techniques such as CT, MRI, PET-
CT, or 4D-CT. These images are often “fused” together to 
give physicians more detailed information about the extent 
of a tumour and the surrounding organs. The purpose 
of this simulation is to create a virtual 3-D reconstruction 
model of the tumour and normal tissues around it as well 
as determine its exact shape and location. Data gathered 
by radiation oncologists and physicists are then used to 
assess the most effective treatment plan.
Following this simulation phase and for each visit, the 
patient is fitted with the same personal immobilisation 
device that has been constructed during this first stage. 
The patient is positioned with the aid of laser lights to 
within a few millimetres of the needed position to ensure 
the tumour is properly aligned with the proton beam. In 
some cases, a CT system will be used to image the target 
before each treatment. During that process, temporary ink 
on the patient’s body can also be used to help position 
the patient. This special alignment and imaging process 
is repeated before each treatment to assure the highest 
precision.
Once positioning and treatment parameters are verified, 
the medical team leaves the treatment room to avoid 
radiation and steps out into the control room; the treatment 
starts, and the patient is monitored to ensure his/her safety 
and comfort. Once the prescribed radiation dose has been 
delivered, the computer shuts off the proton beam and the 
technologists re-enter the room to assist the patient in 
removing the immobilisation device.
Post-treatment, the patient is escorted out of the room 
and returns home until the next daily fraction where the 
treatment process is repeated until the total planned dose 
is reached.

Experiencing proton therapy, from the hospital’s point of view
Hospitals and cancer centres are facing several urgent imperatives: to strengthen clinical quality; increase the delivery of 
personalised, patient-centred care; improve the patient experience; and enhance their efficiency and productivity. Consequently, 
they must introduce innovations in care delivery, often to achieve multiple aims. These innovations include purchasing new 
technologies to deliver better-quality care, adopting lean and standardised processes to improve quality and optimise productivity, 
increasing the use of automation to change how the clinical workforce is deployed, and harnessing patient-generated data to 
personalise treatments. 
In response to these strategic imperatives, medical technology providers must adapt themselves and offer the right product 
offering.  This is particularly relevant for the proton therapy industry.
Strategic imperative
What proton therapy brings
Strengthen clinical 
quality
•	
Proton therapy offers unique medical advantages; it is the latest advancement in radiation 
oncology;
•	
Having proton therapy in the service offering is a magnet for hospitals when attracting key talents 
and patients.
Deliver a more 
personalised 
treatment
•	
Proton therapy is the most targeted radiation-based technique; the opportunity to deliver 
minibeams and provide a fast rate of deposition of protons onto the target is essential in sculpting 
radiation doses based on the irregular shape of the tumour and treating moving targets;
•	
Preliminary scientific data suggests a strong synergistic potential for combining proton therapy 
and developing approaches, such as immunotherapy, making personalised treatment a more 
tangible and effective reality. This combination – which leverages the unique features of LIGHT, 
including its high precision and ultra-fast delivery – offers the opportunity to treat cancer types 
which can not be treated today.
Improve the patient 
experience
•	
Proton therapy is painless;
•	
Reducing the number of patients’ visits through hypofractionation and installing proton therapy 
systems at proximity to patients represent a breakthrough in terms of patient experience and 
comfort.
Enhance efficiency 
and productivity in a 
cost-effective way
•	
Setting up a proton therapy facility is complex and time-consuming; reducing this complexity 
is essential to limit disruption of the management teams of hospitals as well as accelerate the 
returns on investment;
•	
Ensuring a smooth integration between the proton therapy department and the other existing 
functions helps generating synergies and efficiency;  
•	
Proton therapy systems must include the latest software developments, including the optimisation 
of the patient workflow and facility management;
•	
The proton therapy equipment must be affordable, both in terms of upfront and running costs.

Experiencing proton therapy, from the payer’s 
point of view
It is widely accepted that proton therapy is more effective 
than conventional radiation for treating certain cancers, 
such as paediatric, spine, and head and neck tumours. 
Proton therapy is more likely to cause less damage to 
surrounding healthy tissue and organs and its precise 
delivery can mean fewer complications for patients, 
especially in the long term; that precision also means 
protons can be delivered in higher doses requiring fewer 
treatments than conventional radiation therapy. Therefore, 
proton therapy is widely reimbursed for the above cancer 
types across the world.
Yet, particularly in today's healthcare landscape, the cost 
of any care is a large and growing focus for physicians, 
hospitals, patients, insurers, and governments. Proton 
therapy is no exception. It is generally viewed as an 
expensive radiation technique – around two to three 
times the cost of Intensity Modulated Radiation Therapy 
("IMRT"), the latest technological advancement in 
delivering X-rays. Building and operating a proton therapy 
centre with a legacy system is a costly proposition. Against 
that background, the questions around pricing and payers’ 
acceptance for new indications must be taken in a broad 
context:
•	
Radiation therapy remains the most established 
cancer modality, with up to two-thirds of cancer 
patients in the US receiving radiation. It is also the 
most economical cancer therapy. A study published 
in October 2021 by a team of Penn State College 
of Medicine researchers showed that drug costs 
represent the most expensive category for treating 
cancer patients, about twice as much as surgery 
or radiation. As an illustration, recent developed 
agents, such as CAR T-cell therapy, may cost up 
to almost $500,000 per year per patient and many 
new immunotherapies have price tags in excess of 
£100,000 per patient per year;
•	
Given the benefits of proton therapy, many patients 
self-refer; 
•	
With high treatment costs and limited capacity, 
decisions on which adult patients to treat with proton 
therapy must be based on the relative value compared 
to the current standard of care. Cost-benefits analyses 
are the gold-standard method for doing this. Benefits 
of proton therapy are evident when considering that 
both proton and standard photon radiation achieve 
the same goal of damaging tumour cell DNA, but 
the former is associated with significantly fewer side 
effects. From a cost perspective, one must consider 
the treatment tariff, but also the cost for managing 
the side effects and the financial impact associated 
with a lower quality of life post-treatment. Significant 
research activity is ongoing with a growing body of 
evidence supporting the use of proton therapy and its 
clear financial benefits when addressing side effects 
and quality of life. Preliminary data bodes well for the 
expansion of the reimbursement schedule to new 
cancer types;
•	
Briefer 
courses 
– 
with 
the 
emergence 
of 
hypofractionation (refer to pages 47 and 50-51) 
– have resulted in greater acceptance and wider 
reimbursement schemes. Radiation oncologists have 
embraced this trend, which is expected to continue 
and further contribute to the increasing value of proton 
therapy to health systems and payers, particularly as 
the cost per treatment – and not the cost per fraction 
– is set to decrease.

Proton therapy was associated with a substantial reduction in the rates of severe acute side effects — 
those that cause unplanned hospitalizations or trips to the emergency room — compared with conventional 
photon, or X-ray, radiation for patients treated with concurrent radiation and chemotherapy […] While there 
have been other studies suggesting that proton therapy may have fewer side effects, we were somewhat 
surprised by the large magnitude of the benefit.

term side effects, such as abnormal growth, neurological complications, lower IQ, heart, lung and intestinal side effects, and second 
malignant tumors." In addition, it also includes central nervous system tumors, sinus tumors, skull base and sacral chordomas (sacral 
chordomas) and so on. Re-treatment of tumors that have undergone radiotherapy can also benefit from proton beam therapy. Dr. Li 
pointed out that clinical research and trials on tumors in the head and neck, esophagus, lungs, breasts, liver, pancreas, and prostate 
are still ongoing. The current challenge is how to obtain mature data to make objective comparisons between proton beam therapy 
and modern advanced radiotherapy techniques, such as intensity-modulated radiation therapy.

ANNUAL REPORT 2021

Cancer in children and young people is 
thankfully much rarer than cancer in adults.
Survival is higher too: more than eight in 
ten children and young people in the UK, 
aged 0 to 24, survive their cancer for ten 
years or more, compared to one in two 
adults in England and Wales aged 15+.
Important 
differences 
exist 
between 
childhood and adult cancers in terms of the 
type of cancer, how far it spreads, and how 
it is treated. For example, by the time they 
are diagnosed, 80% of paediatric cancers 
have already spread to other parts of the 
body, compared to about 20% of adult 
cancers.
Up to 30% of children who survive 
experience serious, long-term side effects 
from their treatment. Proton therapy is 
ideally suited for paediatric cancers. 
However, cancer remains the principal 
cause of death by disease in children 
beyond the age of one. Without additional 
investment in childhood cancer care, 
over 11 million children aged 0 to 14 are 
expected to die from cancer over the next 
30 years worldwide. The vast majority of 
those – more than 9 million deaths (84%) 
– will be in low-income and lower-middle-
income countries. In 2020, over 15,500 
children and adolescents in the European 
Union were diagnosed with cancer, with 
over 2,000 young patients losing their lives

At Advanced Oncotherapy, we feel it is our responsibility to support children. We are committed to do so by democratising 
access to proton therapy.

The availability of and the demand for proton therapy is growing exponentially. However, in absolute terms, the availability is 
still very low. There are currently only 114 operational proton therapy facilities in the world, addressing less than 5% of clinical 
demand. Only less than 1% of all radiation therapy patients receive proton therapy, even though between 15% and 50% 
would benefit from it. The reason for this discrepancy is the high cost and the large size of the equipment, which does not fit in 
conventional treatment spaces. The primary factor contributing to this is the use of legacy circular proton accelerators which 
bring significant challenges and constraints in terms of cost and size.
THE MARKET UPTAKE AND 
THE NEED
Originally, most patient treatments with high energy protons have been carried out at large-scale research facilities such as 
the Harvard Cyclotron Lab or Paul Scherrer Institute, by installing an extra treatment room besides several experimental 
target stations used for fundamental research in nuclear physics. In the 1990s, first stand-alone centres have been built 
and dedicated to treat cancer patients with proton therapy. One of the first was the cancer centre in Loma Linda in the US, 
a centre set-up by Optivus with the installation and servicing activities led by Ed Lee, the COO of Advanced Oncotherapy.

We have developed the LIGHT system to address the 
key limitations of conventional and circular proton therapy 
machines; it has been designed to deliver superior medical 
outcome whilst providing a proton treatment environment at 
a fraction of the cost, footprint, and operational complexity of 
legacy systems. We believe this enables the deployment of 
proton therapy into a broader variety of cancer care facilities, 
creating greater access for more patients. 
The LIGHT system has been designed to enable delivering 
most of the treatments in a comfortable seated patient 
position. The comfortable patient position ensures better 
patient immobilisation, the critical factor in delivering 
radiation treatments both safely and effectively. It also allows 
treating patients with impaired breathing who cannot lie 
down due to asthmatic attacks. In addition to ergonomic 
benefits, patient’s accommodation before treatment in a 
seated position stabilises the motion of internal organs. 
The seated positioning minimises the motion magnitude 
by a factor of 4 and shifts the heart toward the diaphragm. 
Such anatomical and physiological characteristics ensure 
effective and safe irradiation of lung, breast, chest wall, and 
upper gastrointestinal tissues sparing the damage of the 
critical healthy organs like heart. The treatment setup also 
guarantees better treatment outcomes in treating tumours in 
liver, pancreas, kidney, as well as head and neck and brain.
The heart of our LIGHT system is our proprietary linear 
proton accelerator that integrates with an in-room sliding 
Computerised Tomography (CT) scanner, a robotic 
positioning system, and the patient support system, real 
time X-rays modules, the room control system, and a full 
suite of medical software.
The LIGHT accelerator
The LIGHT accelerator accelerates protons to a high 
speed by subjecting them to a series of oscillating electric 
potentials along the linear beam line. What makes LIGHT 
as a linear proton accelerator preferable to circular 
accelerators is that the energies of the accelerated protons 
OUR LIGHT 
SYSTEM
can be adjusted rapidly, i.e., in milliseconds, and without loss 
of beam intensity. The beam energy determines how deeply 
the protons penetrate tissue, so this ultra-fast tunability is 
useful for adjusting the beam position within the body as the 
patient breathes or to precisely hit different spots on a tumour.
The in-room sliding CT scanner 
The LIGHT system includes a big Bore CT scanner that is 
integrated into a uniquely designed sliding platform. The setup 
enables scanning a patient in the treatment position while 
keeping the patient stationary. The scanner has 85 cm opening 
size suitable for scanning, and then treating, oncology patients. 
The scanner is installed with the special software capabilities 
for low dose scanning. The mode enables generation of 
high-quality images while exposing the patients to only 20% 
of the standard radiation level. The scanning supports both 
helical and axial modes with fast image acquisition. The 
images can be used for treatment planning, for positioning, 
and for adaptive therapy. Other key features include 4D CT 
capabilities; low dose image acquisition; up to 204 kg patient 
load; and additional pendant operating panel.
Treatment planning at a correct phase of the breathing 
cycle is crucial for delivering the treatment dose accurately. 
Having the 4D CT integrated in the treatment room allows 
verifying the breathing cycle pattern prior to each treatment 
event, particularly for treatment of breast, lung, and upper 
gastrointestinal tumours. The 4D capability is possible with 
helical and axial scanning modes. To accurately “position” 
the beam on the target, the belt-based approach is used. 
Synchronisation between the belt motion and multiple CT 
dataset enables acquisition of ten separate scans defining 
the most appropriate target for treatment.
The robotic positioning system and the patient 
support system
The robotic arm is the robotic patient positioning system, 
with 6 degrees of freedom. The base of the robot is 
placed on the floor. The reach of the distal arm enables 
the positioning of the patient in both seated and laying

positions at imaging setup, and at treatment isocentre.
The real time X-rays module 
In order to visualise the patient anatomy in real time, the set of 
orthogonal X-rays sources and detectors are integrated into 
the system. The system is static and enables to image the 
patient at treatment isocentre during the actual treatment. 
The system can image the patient in both seated and 
laying positions. The imaging information serves for precise 
patient positioning with 0.5 mm accuracy. The imaging is 
based on registration of digitally reconstructed radiographs 
generated from treatment planning CT and actual X-ray 
images received prior to or during the treatment.
The room control system
The room control system is responsible for delivery and 
monitoring of the LIGHT particle beam: The LIGHT Room 
Control System is the system that controls and monitors the 
delivery of proton irradiation to the tumour, and provides a 
user interface for the radiographer to start, stop, or interrupt 
the beam delivery. It consists of sub-systems, including the 
LIGHT Enhanced Nozzle System, traditionally referred to 
as the nozzle, that controls and monitors irradiation; and 
the Light Redundant Charge Recorder, which provides the 
direct hardware interface to the radiographer.
The computing medical software suite
Proton therapy systems include a wide range of software, 
ranging from the preparation of the full treatment plan, 
daily proton delivery to patient workflow and recording 
of patient data. To respond to one of the key challenges 
currently faced by end users – namely the lack of an 
integrated control software suite – we have worked with 
Raysearch and successfully tested a seamless software 
suite customised for LIGHT. This provides users with 
a single interface for patient preparation, treatment and 
follow-up processes, whilst limiting potential risks and 
facilitating a better end user experience for clinicians and 
healthcare workers. 
The major components of the medical software package 
include:
•	
Treatment session manager (TSM). The TSM 
software developed by Raysearch, acts as the control 
system to connect and manage various sub-systems 
of the LIGHT system. It allows the management of 
the daily proton treatment for patient delivery.
•	
Treatment planning system (TPS). The TPS software 
provides superior functionality for treatment planning, 
encompassing 
patient 
positioning 
through 
to 
treatment solutions. The software is well established 
and familiar to oncologists.
•	
Oncology information system (OIS). The OIS is the 
software, developed in partnership with Raysearch, which 
integrates with the TPS to offer managed workflows and 
to enable patient treatment to be modified daily.

The Medical Treatment Room (MTR) required for the clinical treatment of patients with the LIGHT system has been 
completed at the Company's Daresbury integration site. Subsequently, the necessary permissions have been received to

Proton therapy requires high accuracy placement (positioning) of the patient, typically with 1 mm tolerance or less. As such, 
the Company has developed and installed in the MTR a bespoke LIGHT Patient Positioning System (PPS) to provide 
the required accuracy in a compact and efficient system. The PPS comprises of a robotic patient positioner for aligning 
patients in the upright position in a treatment chair, a CT imaging subsystem, an X-Ray imaging subsystem, and computing

LIGHT Patient Positioning System
The LIGHT Patient Positioning System (PPS) is a medical device used for volumetric imaging in the
upright position for treatment planning, and the safe and accurate positioning of the patient during
treatment delivery. Components of the PPS include the CT and X-ray imaging systems, as well as a
Patient Positioning Device (PPD), comprised of a chair mounted on a robotic arm. These components
are controlled by software, which communicates with the Treatment Control System (TCS). Use of the
LIGHT PPS, along with a fixed-beam delivery system, is both space and cost-effective, facilitating
instalment with less infrastructure than conventional proton therapy systems.
The LIGHT PPS allows patient imaging and treatment in the upright position (Figure 3) within a fixed-
beam treatment room. Accuracy and reproducibility of the PPS devices are very important in their
design and development. The compact nature of the LIGHT PPS reduces cost and space
requirements for new Proton Therapy Facilities.
Clinical Capabilities of the PPS:
• Set up patient
• Move to imaging position
• Acquire images
• Image registration
• Move to treatment position
• Move to beam position
• Verify and correct position
• Treatment delivery
• Unload patient
• Imaging for treatment planning
• Clinical QA
• Clinical system commissioning

The high cost for gantry installations is a major limitation 
to the expansion of proton therapy facilities. An 
alternative technical option is provided by fixed-beam 
treatment rooms (see Figure 1), where the patient is 
rotated and translated in space by a robotic arm to 
enable beam incidence from various angles.
Lasers in the Treatment Room are used for initial patient 
setup.
The LIGHT Patient Positioning System (PPS) includes a 
chair mounted on a robotic arm, and a CT scanner 
mounted on a vertical sliding platform (Figure 2a), which 
allow for imaging in the upright position (acquiring the CT 
for treatment planning or for image guidance during 
treatment delivery).
The robotic arm can then move the patient to the 
treatment position, where orthogonal images of the 
patient can be acquired by the X-ray system (Figure 2b) 
for comparison with images digitally generated from the 
treatment planning CT image, allowing for position 
adjustments to be made (if required) prior to treatment 
delivery.

Why does that matter?
Absorbers are mechanical devices of varying 
thickness found in the beam path at the exit of 
legacy circular accelerators. They are used to slow 
down the maximum energy of protons, in such 
a way that the killing effect of radiation occurs at 
the right depth in the patient’s body. They release 
additional secondary particles and waste many of 
the protons in the process, which is reflected in a 
low transmission. For example, only 20% of the 
protons accelerated to an energy of 170MeV reach 
the right target area, i.e., the tumour, the remaining 
80% being lost in induced stray radiation that must 
be contained to protect staff through thick and 
expensive radiation shielding. This is a key driver 
of the large footprint needed and prohibitive cost to 
house conventional proton therapy systems.
 
LIGHT vs legacy circular accelerators
LIGHT does not include absorbers unlike legacy 
circular accelerators because the energy of protons 
is controlled electronically.
Why does that matter?
The destructive effect of radiation occurs when 
accelerated and energised protons stop. Therefore, 
a proton therapy equipment must be able to change 
the energy of protons, so that radiation is deposited 
onto the tumour at different spots and depths. At 
an energy of 230 MeV, a proton beam will deliver 
most of its radiation in the patient’s body at a depth 
of 32 centimetres, that specific spot being called 
the Bragg peak. A proton therapy which has a fast 
energy change is more suited for adaptive treatment 
and addressing the issue of organ movements. 
 
LIGHT vs legacy circular accelerators
Legacy circular accelerators use slow-moving 
mechanical devices at the exit of the proton 
therapy system. In contrast, the energy of protons 
is controlled electronically with a LIGHT system. 
LIGHT and its rapid electronic energy changes at a 
repetition rate of up to 200 times per second – up to 
200 times faster than legacy systems – provide the 
opportunity to deliver a more conformal treatment 
and a better treatment of moving organs.

THE UNIQUE ADVANTAGES OF 
THE LIGHT ACCELERATOR

Why does that matter?
Modularity offers advantages for installation, 
commissioning, transportation, maintenance, and 
dismantling.
 
LIGHT vs legacy circular accelerators
LIGHT is made up of a series of modules which 
can all be assembled at the customer site. 
This is contrast with legacy circular accelerator. 
Consequently, LIGHT can be retrofitted into existing 
buildings through the assembly of individual 
components directly at the customer’s site.
Why does that matter?
Protons are charged particles. They can be 
deflected and directed to a target through magnets. 
A large cross section requires large and expensive 
magnets, making the installation process more 
challenging. Clinically, a small beam cross sections 
allows to deliver a more targeted treatment to 
patients.
 
LIGHT vs legacy circular accelerators
Legacy circular accelerators have a large cross 
section, approximately between 4 and 36 times 
bigger than the LIGHT mini-beam cross section.

THE UNIQUE MEDICAL 
ADVANTAGES OF THE 
LIGHT SYSTEM
47
ANNUAL REPORT 2021
THE ONLY SYSTEM INTEGRATED 
WITH AN IMAGING SYSTEM
The LIGHT system is fully integrated 
with a diagnostic grade, fan beam, wide-
bore CT scanner in the treatment room. 
The seamless integration between the 
treatment planning, treatment control, 
and CT scanner provides unparalleled 
versatility for on the fly adaptive proton 
therapy, the next step in personalised 
medicine.
THE SIZE OF THE BEAM
The LIGHT system can have a 
significantly smaller proton beam than 
legacy systems. Fundamentally, IMPT 
(intensity-modulated proton beam therapy) 
systems depend on conformity's spot size 
(emittance). Having the smallest beam 
size, minibeams provides the utmost 
conformity, expected to improve outcomes 
for many indications.
THE OPPORTUNITY TO DELIVER 
FLASH TREATMENT
LIGHT is the ideal system to deliver 
FLASH because the LIGHT system proton 
output does not vary with energy. Hence, 
instead of "shooting thru" the patient as 
with legacy FLASH deliveries, the FLASH 
LIGHT treatments resemble current proton 
therapy treatments, except they go much 
faster. Unlike other proton systems, this 
allows both conformal and FLASH in the 
same treatment with the LIGHT system.
THE CONSTANT SPOT SIZE
The LIGHT system features a constant, 
small spot size from 150-230 MeV. The 
spot size increases with decreasing 
energy for all other systems. The 
LIGHT constant spot size has been 
shown to improve treatment plan quality 
(conformity) in comparison to legacy 
systems.
UPRIGHT TREATMENTS
LIGHT's capacity for upright seated treatment 
can improve cost, quality, and patient 
comfort. Lung volume is greater (averaging 
27%) in the upright position, resulting in less 
tissue density within the radiation field and 
potentially less irradiated normal tissue mass. 
Upright positioning can be more reproducible 
for breast patients and pelvic patients. It is 
also expected to be more comfortable for 
head and neck patients, many of whom 
have difficulty swallowing. The accumulation 
of saliva can make breathing difficult in the 
supine position. Because of gravity, upright 
positioning is more comfortable for the head 
and neck patient.
THE CHANGE OF ENERGY
Due to fast energy changes, LIGHT 
rescans much quicker than any other 
proton therapy system. This rapid energy 
change means LIGHT is ideally suited 
for volumetric repainting of tumours, 
conformity of the radiation dose, and 
tracking moving tumours.

uniquely designed accelerator to a state-of-the-art treatment

Further development has progressed this year with applications of the LIGHT system. Our LIGHT application developments 
are primarily based on the disruptive LIGHT system generated proton beam properties: beam size and 3D spot position 
delivery speed. Secondarily, our developments focus on revolutionary imaging and treatment in the upright (seated) position. 
We are also exploring new applications for the LIGHT system in a non-cancerous medical treatment context.
Proton Minibeams
The LIGHT system produces a class-leading proton beam quality designed to deliver spot sizes less than one mm Gaussian 
sigma, called proton minibeams (“MB”), which are much smaller than beam sizes produced by legacy circular accelerators. 
This year, together with our research partner, the Cleveland Clinic, we investigated the potential clinical advantages of proton 
minibeams compared to photon and cyclotron beams (“CB”). We have reached more than 60 patients with brain, head and 
neck, and lung cancers. The results are presented at scientific conferences such as the American Society for Radiation 
Oncology ("ASTRO") and the American Association of Physicists in Medicine ("AAPM"). Below is a resulting comparison from 
our work "Can proton linear accelerator beams and minibeams achieve superior plan quality over cyclotron generated proton 
beams and photons in treating multiple brain metastases?"
FLASH
Recent in vivo studies in mice1 demonstrated that electrons delivered to 
cancerous tissues at high dose rates within 0.5 second (FLASH), inhibit 
tumour growth equally as in conventional therapy, but with significantly 
more sparing of surrounding healthy tissues. Normal tissue sparing with 
FLASH enables a dose increase without additional complications, widening 
the therapeutic window and virtually reducing the number of fractions to 
one single fraction/visit.
Hence, FLASH radiotherapy, where the entire patient treatment is 
administered in less than 0.5 second, shows great promise in sparing 
patients from the toxicity burden of radiation therapy. 
Proton FLASH, compared to other types, should have no exit dose. Proton 
FLASH has been investigated using cyclotrons. These machines can 
produce FLASH at their extraction (maximum) energy. However, at shallow 
and medium depths, the dose rate is significantly reduced due to degraders 
and range shifters. Moreover, these passive scattering methods to irradiate 
the target generate a higher number of neutrons and unwanted scattering, 
which could hinder FLASH's advantages. FLASH may not be possible with 
synchrotrons or synchro-cyclotrons.

Note: From the pioneering work, it was demonstrated 
that high dose rate doses (17-Gy FLASH 4.5 MeV) may 
have a strong tissue sparing effect, compare the 17-Gy 
FLASH 4.5MeV column with the unirradiated Control, they 
appear the same. This may also permit dose escalation, 
improving the therapeutic index (Figure 1). Compare the 
FLASH dose of 30-Gy, at about 2x with the 17-Gy non-
FLASH (CONVentional) column, the FLASH irradiation still 
looks less damaging.

Two aspects of the LIGHT system performance are uniquely suited to FLASH. Unlike legacy systems, the proton beam 
intensity (current) does not vary on the energy, and energy changes are ultra-fast. These advantages support LIGHT in 
delivering FLASH conformally to any site in the body. 
This year, we pioneered further developments in "scanned conformal FLASH" (SCF). In comparison to legacy technology, SCF 
presents a major advantage with the LIGHT system. This is because, due to the associated thick energy absorbers, cyclotrons 
can only produce FLASH at a single, maximum energy, making their FLASH treatment like X-rays, i.e. their proton beam 
must penetrate the entire patient and exit outside of the patient. This “shoot-through” technique is called Transmission Beam 
(TB). TB is “not how protons are meant to work,” i.e.  it looses the advantage of the proton beam stopping the Bragg peak in 
the tumour. Cyclotron systems seek to avoid this by using further custom patient absorbers, but this approach is also inferior. 
Superiorly, only LIGHT, due to its ultra-fast energy changes and high beam output, can deliver SCF, retaining the advantage 
of proton therapy conformity, with the proton beam stopping in the tumour (Stopping Beam SB), and adding FLASH on top.

Upright treatment
The LIGHT system features upright (seated) treatments. Most current radiotherapy is performed with the patient laying on 
a treatment “bed”, called the supine position. Because upright is different from supine positioning, we have investigated the 
possible benefits of upright vs supine patient positioning. Our upright positioning investigations have progressed. This year, 
the LIGHT Patient Positioning System (L-PPS) was installed at the Daresbury Integration Site. We are preparing to scan 
the first human patients in the upright position with the L-PPS. The below shows the L-PPS installed with an artificial human 
mannequin prepared for CT imaging in the upright position.

Last year, we partnered with the UK National Physical Laboratory (NPL) to assess the accuracy of our L-PPS "cubic 
phantom," used for the calibration of our system. The study results indicated excellent L-PPS cubic phantom accuracy. 
According to the NPL, "the standard deviation of the centre-to-centre distance of spheres was  less than 20 μm". 
The LIGHT potential beyond cancer 
A promising topic is a consideration of using LIGHT to treat non-cancerous diseases. The indications we are exploring include 
the treatment of cardiac arrhythmias, hypertension, epilepsy, age-related macular degeneration (ARMD), and addictive 
behaviours, naming a few non-cancer areas we intend to study. For example, cardiac arrhythmias are a significant contributor 
to sudden cardiac death and are commonly treated by catheter ablation. However, the success rates of catheter ablation in 
these diseases are limited, and catheter ablation is linked to several complications. By employing LIGHT proton minibeams 
and split-second beam energy changes, Advanced Oncotherapy intends to develop a non-invasive treatment.
Similarly, the LIGHT System has the potential to be used for non-invasive ablation of arteriovenous malformations associated 
with epilepsy and renal nerve ablation to help regulate blood pressure in unregulatable patients. The below demonstrates how 
the LIGHT mini beams will be used to target the renal nerve nexus. The LIGHT mini beams are minimally invasive, avoiding 
the spinal cord, and such treatment may free patients from pharmaceutical dependence for hypertension.
Another opportunity for future growth is the use of LIGHT to reduce or eliminate the frequency of anti-VEGF treatments 
for ARMD patients. Furthermore, pre-clinical activity is expected to establish the feasibility of using LIGHT mini-beams to 
modulate dopamine transmission from the nucleus accumbens to treat opiate addiction.

ANNUAL REPORT 2021
What made you join Advanced Oncotherapy?
I came to radiotherapy wanting to make a difference to 
improve patient outcomes. Early in my 20+ year career, 
I learned that I had the aptitude to develop and improve 
advanced radiotherapy systems, specifically particle 
therapy systems, thereby benefiting many patients. Joining 
Advanced Oncotherapy and assisting in developing the 
first proton therapy linear accelerator system is the ultimate 
expression of this goal. And the first day I met the Advanced 
Oncotherapy team, I knew it was where I wanted to be. 
Collaborating with my colleagues, all world-class experts in 
their respective fields, we deliver the future of radiotherapy 
and make it more accessible than ever before.
As a medical physicist, what do you find 
particularly exciting about LIGHT?
As the new platform for proton therapy, LIGHT is poised 
to realise the true promise of proton therapy. I say this 
because two aspects holding us back from that ideal 
today are uncertainties with target motion management 
in proton therapy and the need to improve the high dose 
conformity for some clinical indications. The LIGHT 
system is uniquely capable of ultra-fast energy changes, 
and the smallest beam size is called proton minibeams; it 
is designed to address the two challenges directly. 
What is motion management and how important 
is it?
Motion management is more vital in proton therapy than 
with the more common X-ray therapy. This is because 
proton therapy is more accurate than X-ray therapy. 
Consequently, the "fuzzy" X-ray beams are not as strongly 
affected for moving targets if a tumour briefly moves away 
from the ideal treatment location, whereas a proton beam 
might completely miss it. Hence, motion management is 
obligatory for proton therapy. There are different types of 
motion management; the most basic enlarges the treatment 
region, thereby assuring coverage, but this is not ideal for 
patients, as it irradiates more healthy tissue than necessary, 
potentially limiting the efficacy of the treatment or causing 
later treatment-related complications. The LIGHT system 
is designed to provide improved motion management by 
tracking the tumour during treatment and staying "locked 
on" to it like a smart bomb. We expect this could result in 
improved clinical outcomes for some indications.
What about size of the beam?
The size of a proton beam spot is a critical treatment quality 
parameter. The most advanced type of proton therapy, pencil 
beam scanning, actively moves the beam across the tumour 
during treatment. And the regular beam diameter in proton 
therapy is about the width of a pencil, hence the name. But if 
you made a drawing with such a dull pencil, it would look very 
blurry, which is directly analogous to what happens inside the 
patient. Instead, if you had a very sharp pencil, say a 0.5 mm 
mechanical pencil, for example, the drawing would be razor-
sharp. Incidentally, 0.5 mm is about the size of the LIGHT proton 
beam as it exits the linear accelerator, a unique aspect of LIGHT.

Using this sharp beam size, called minibeams, our calculations 
indicate a potential patient benefit for many indications. We are 
currently exploring this advantage together with the Cleveland 
Clinic, evaluating the potential for many of their patients.
For which cancer types do you expect these 
clinical aspects will be most appropriate?
The LIGHT system is designed to treat all clinical indications 
suitable for proton therapy. But the unique aspects of LIGHT, 
such as motion management and minibeams, are ideal for 
specific uses. Specifically, LIGHT minibeams may provide 
the most significant benefit where the ultimate normal tissue 
sparing is needed, such as with brain tumours abutting the 
brainstem or optic nerves. But LIGHT minibeams also show 
great promise for radiosurgery in the lung. The LIGHT motion 
management features are naturally associated with tumours 
that have motion during treatment; these are found in the 
thoracic cavity near the diaphragm, such as the lungs and 
liver organs. We see the most significant potential to expand 
the treatment of thoracic tumours with the LIGHT system and 
expect it is only a question of time before the adoption grows.
How 
do 
you 
see 
the 
journey 
towards 
commercialisation as the physicians tend to be 
conservative when new technologies hit the market?
Advanced Oncotherapy's LIGHT system offering has 
advantages in two broad areas, commercial and clinical. 
The greatest hindrances to the broader global penetration 
of proton therapy are its cost and complexity: not only 
complexity in terms of its use but also complexity in terms 
of a proton therapy endeavour realisation. To lower the 
entry bar, our Company has developed an appealing 
solution from the ground up. Examples of our solution 
are that no individual LIGHT component is larger than 
a "Class C" shipping container. Each of the modular 
linear accelerator components can fit on a tabletop. This 
dramatically simplifies shipping and installation. Hospitals 
are designed to accommodate the installation of CT 
scanners and MRI units; the installation of LIGHT is more 
akin to those than legacy proton equipment which requires 
road closures and giant overhead cranes.
In terms of LIGHT system usability, this is another area we 
have developed to ease the transition to proton therapy for 
centres. The LIGHT system use is "workflow-driven," hence 
the new user is not wondering what the next step is. The 
management software directs and supports their work.
Also, we tend to focus on the technical innovations at 
Advanced Oncotherapy, but our financial and commercial 
developments are equally as innovative. In addition to 
offering Turn-key proton therapy facilities, together with 
our partners, we have sophisticated financial solutions we 
can offer our customers. This key Advanced Oncotherapy 
solution can make the difference between realising a new 
proton therapy centre or not.
I have already touched on some of LIGHT's differentiating 
clinical design aspects, focused on additional healthy tissue 
preservation and reducing the toxicity burden sometimes 
associated with radiation therapy. Every clinician is keen to 
improve the care of their patients. Even if it requires change, 
physicians are convinced by the opportunity to change 
practise for patient benefit. The LIGHT system keenly appeals 
to this desire. In summary, I am confident that the unique 
combination of best-in-class treatment and our commercial 
advantages, Advanced Oncotherapy and LIGHT, are bringing 
life-sparing proton therapy to more people in need.
What are you and your team currently working on in 
the clinical space?
Together with my team, my role is roughly split into bringing 
our first LIGHT system into clinical use and exploring and 
developing applications of the LIGHT system.
Naturally, our top priority is beginning patient treatments 
at our Daresbury integration site, in the UK, something 
I personally pushed very hard for. We were delighted to 
receive the approval of the UK Science and Technology 
Facilities Council to use the facility at Daresbury for patients. 
There is much to prepare, roughly divided into hardware 
and software. We are engaged in realising the Medical 
Treatment Room ("MTR") and Area. The MTR has been 
constructed, and we are actively completing its fit-out and 
testing with the necessary LIGHT sub-components such 
as the CT scanner, robotic treatment chair, and X-ray 
positioning systems. We are also preparing for the required 
proton beam measurements before first use. There is a great 
deal of software control systems to complete and integrate. 
This is typically the Achilles' heel of new proton therapy 
systems, as the effort can be underestimated compared to 
the hardware. With this awareness, Advanced Oncotherapy 
started our LIGHT software development early on. We rely 
on a treatment planning system, a patient database system, 
and a therapy control system. All three systems have been 
running on our servers since 2020. Indeed, there remains 
more work to do, but we are on the straight path to success 
with these systems. The final step is bringing all sub-systems 
together in a coordinated way, resulting in a system ready 
for patient treatment. I have done it before a few times and 
greatly look forward to this result for our company, staff, and 
primarily for the patients that will benefit.
I am also engaged with our current clinical partners, such 
as the University Hospital Birmingham and The London 
Clinic, UK. Together, we are preparing the needed clinical 
treatment protocols for our first patients. Also, we perform 
extensive planning for staffing, training, insurance billing, 
and operations. The Cleveland Clinic, USA, is our close 
research partner. We work together directly to determine 
how the LIGHT system could benefit their patients.
Exploring LIGHT developments is some of the exciting work 
we are engaged in. It is so rewarding because the LIGHT 
system has boundless potential that responds to our ideas in 
the most positive manner. We are pushing into unchartered 
waters, and that is keenly exciting. An example is with our 
FLASH-LIGHT development. The type of treatment called 
Introduction

FLASH is a biological effect where a differential response is 
observed between normal and tumour tissue when exposed 
to ultra-high dose rates. This means that if the entire radiation 
treatment can be given incredibly fast, in less than half of a 
second, the tumour cells are killed, but the healthy tissue 
is almost completely spared from damage. The underlying 
science is still being worked out, but FLASH is the most 
exciting development in radiation therapy in decades. The 
LIGHT system was largely designed when I first became 
aware of FLASH a few years ago. I immediately wondered 
what FLASH might be like with the LIGHT system. I was 
astounded to learn from my colleagues that the proton output 
of our machine does not depend on energy. As we say in 
physics, it is "invariant." As we discovered, the invariant output 
of LIGHT is fundamental to enabling what we call scanned, 
conformal, FLASH, radiotherapy, something no other system 
can perform. There are many other similar examples, some 
we have mentioned, of how the LIGHT system "rises to the 
challenge" of what we ask it. One is left with the impression 
that it was meant to be.
You mentioned FLASH. How do you define the 
opportunity?
FLASH is both a clinical and commercial opportunity. 
Clinically, the reduction of healthy tissue damage can be 
used to "open the therapeutic window." This can be realised 
in either of two ways: either patients can be treated to 
higher tumour doses than are currently possible, or lower 
side effects can be realised from existing dose treatments. 
As different examples, certain lung tumours might benefit 
from higher doses than are presently used. In contrast, 
other tumours such as the prostate are well controlled with 
current doses, and there, the goal is less toxicity to the 
surrounding tissues, such as the rectum. In all cases, the 
goal is to have fewer treatment sessions, ideally just one, 
compared to the multiple weeks of radiotherapy typical of 
treatments today. The patients prefer fewer treatments, 
leading to a win-win commercial opportunity. Treating more 
patients annually produces more revenue, as usually, 
patient treatment is compensated on a per capita basis. 
Proton treatment centres are costly to build and operate. 
Here, FLASH may further make the endeavour attainable 
by more minor concerns, improving community access.
In conclusion, what is driving you?
My personal wish is to have more time in the week. Our 
patients are waiting, depending on the LIGHT system's 
completion and readiness. Whenever the obstacles seem 
high, I think of the patients waiting to be cured with our 
LIGHT machine, patients who live in areas not accessible 
to proton therapy today. The faster we can complete LIGHT, 
the more lives that can be saved. Our company is working 
at the maximum rate. If we could bend time, we could get 
to the goal sooner. We are approaching the end goal now. 
Again, the greatest wish must be for the suffering cancer 
patients without access to proton therapy. So, my motivation 
and my pride are to help these people. This is very much in 
the DNA and culture of our Company, and this is why I get 
up every day with full energy, racing to the goal.

ANNUAL REPORT 2021
You worked at the proton therapy center in Loma 
Linda in California before joining Advanced 
Oncotherapy in Geneva. Why did you move?
The first hospital-based proton treatment centre was 
offered by Loma Linda University Medical Center which is 
in Loma Linda, California. The proton therapy centre has 
treated over 17,500 patients and has been in operation 
for over 25 years. I learned a lot about cancer treatment 
and got to see in person what patients and their family 
experience during their journey of beating cancer: tragedy, 
hope, as well as the tangible benefits and effectiveness of 
proton therapy. After seeing many patients come through 
the Loma Linda Proton Center, I am convinced that proton 
therapy is the best radiation treatment option readily 
available to patients. The challenge is to lower treatment 
cost whereby the oncologist can confidently prescribe 
proton therapy without any pushback from insurance firms 
due to cost factors. LIGHT has the potential to do this.
 
I decided to join Advanced Oncotherapy because of a few 
reasons. The first was the next-generation technology in 
proton therapy. Advanced Oncotherapy’s LIGHT System 
provides the capability to control the radiation dose 
delivered at each single "point" of the tumour. This has 
the potential to dramatically lessen collateral damage of 
healthy tissues, lower the number of treatment sessions 
and hence reduce the treatment cost to patients and clinics, 
increase treatment capacity from a patient throughput 
perspective with upside of increasing treatment center 
revenue to name a few key factors. The second reason 
was the modularity of the design. The LIGHT design 
simplifies the installation by segmenting the system to 
manageable “modules”. For the most part, we only need a 
conventional forklift or equivalent lifting capability to install 
our heaviest module – it can even be manually moved 
by four strong men. The modularity also offers repetition 
during installation. Repetition is a key enabling factor in 
high-volume production. With repetition, we can then 
focus on efficiency and reduction of cost and time. The 
third reason is to participate in a technology that has never 
been done before. Of course, we had our own challenges 
but this is also what motivates me when getting up every 
morning with driven ambition toward helping cancer 
patients realise the best radiation therapy possible.
 
What are the biggest challenges you are facing?
Our challenge can be summarised into one phrase: we are 
producing, for the first time, a very complex and cutting-
edge proton accelerator-based treatment system which will 
be certified and cleared for patient treatment by governing 
authorities such as the FDA. The technology has been proven 
since the data and result of the prototype announcement in 
2018. Hence, the technology is not a concern based on the 
data from the technical team. The remaining challenges are

related to implementation (learning curve of doing something 
for the first time) and cultural evolution. Doing something 
for the first time includes complex design documentation 
with full traceability and technical rationale, documented 
evidence of a business process which is certified per 
ISO 13485, our supply chain partners, and the rigours of 
installation, validation, and verification. We, collectively, have 
implemented many lessons learned toward continuous 
improvement of quality, delivery, and cost during our first 
system deployment journey. There is no one single issue 
but a collection of many low-level technical or logistical 
issues which were overcome through excellent collaboration 
and teamwork. During installation, milestones which first 
took weeks are down to days. These improvements have 
not been easy but with resolve, commitment, and grit, the 
team have proven to be effective, and we are continually 
accelerating our progress. The topical areas include 
personnel skill and knowledge base improvement, continually 
improving installation documentation and processes, early 
identification of faulty components coupled with effective and 
efficient countermeasures, applying pre-assembled kits and 
assemblies to minimise critical path activities, and applying 
rigours test and inspection processes to name a few.
 
The organisational culture evolution is transitioning from a 
pure R&D organisation towards a commercial organisation 
while still maintaining our roots in R&D and with our affiliation 
with CERN and STFC. Our staff are responding well as time 
progresses. Since I joined five years ago, we are continually 
shaping our organisation to have the right balance between 
commercial and R&D mindset. The second challenge is 
the “nuts & bolts” of the business which is the technical file. 
The technical file provides the full detailed documentation 
package which traces from requirements (clinical and 
business-case) all the way down to the specifications of wires, 
nuts, and bolts. The documentation package includes design 
selection rationale, conceptual design related data, detailed 
design documentations, risk assessments at all levels, all 
aspects related to supply chain and logistics management, 
manufacturing, installation, test, and inspection data. This 
rigour is applied to the LIGHT system, sub-systems, sub-
sub-systems, assemblies, sub-assemblies, and components 
related to the LIGHT system. The similar discipline is also 
equally applied to the building and infrastructure at our first 
system deployment site in STFC-Daresbury Laboratory 
whereby we have received patient treatment approval. In a 
nutshell, doing “this” for the first time, there is no published 
manual we can refer; we are creating the manual and we will 
be the experts. I am very proud of our team’s progress.
 
Is that the reason why the Company has decided 
to outsource the manufacturing process and 
focus on the assembly processes?
As a key business strategy to minimise financial costs, 
we outsource all manufacturing activities but perform the 
necessary assemblies. We can leverage the immense supply 
chain network, their capital equipment, and component and 
assembly know-how to produce the components while we 
focus on the assembly and integration of the system. This is also 
possible because we have ample knowledge and expertise in 
the manufacturing realm. Without our manufacturing expertise, 
we would not be able to outsource the manufacturing of our key 
components. Further to this point, we rely on our relationship-
building capability to transform a traditional customer-supplier 
relationship to a partnership. The key enabler is doing what we 
say and saying what we do, which relies upon integrity and 
transparency. The announcements with VDL and CosyLab 
are evidence of our transformation from a supplier-customer 
relationship to a supply chain partnership. Our aim is to 
advance our existing partners toward a higher tiered platform, 
for example by advancing from a component provider to a sub-
system provider. There is much work to be done to realise this 
strategy; however, we believe this is key toward meeting the 
future pent-up demand of our LIGHT system. Coupling supply 
chain partnerships with strategic tiered platforms will provide 
capacity expansion as well as adapting to the everchanging 
geopolitical and environmental variations. We will maintain our 
manufacturing and integration know-how while partnering with 
our suppliers to foster and maintain a win-win relationship.
 
How do you manage your supply chain?
We apply the robust supply chain management based 
on the experiences of our staff who come from radiation 
therapy medical device, automotive, aerospace, defence, 
nuclear, high-energy physics, utilities, and construction to 
name a few. This starts with a clear scope of work, detailed 
and clear requirement and specifications, progressive 
Q&A review session to ensure input information are clearly 
understood by our supply chain partners, rigorous contract 
negotiation to ensure the interests of the Company are at the 
centre of all negotiations while maintaining our partnership 
spirit, robust audits related to quality and business systems, 
identification and management of deliverable milestones, 
strategic supplier visits to “kick the tires” and verifying 
milestones in progress as well as certificate of conformance, 
factory acceptance testing and inspection, site acceptance 
test and inspection, and compliance review of our suppliers’ 
traceable documentation packet. 
 
We also have implemented and plan to bolster the supply 
chain management practice of commodity assignments, 
supply chain project engineering practices which include 
expertise in specific areas to complement our supply 
chain partners, performance measurements coupled with 
routine feedback and reviews, standardised quality and 
regulatory compliance agreements, and recurring supplier 
audits to name several key initiatives.
 
Which initiatives do you foresee for future 
machines?
We aim to launch several key initiatives to reduce cost, 
lead time, and further improve quality. Our partnership 
model will extend to recurring cost reduction initiatives 
with measurable goals. We have, even now, realised cost 
savings of our first treatment system compared to the 
first prototype which include but are not limited to value 
engineering; we will continue this practice. The aim of cost 
reductions is not only to increase profitability but, most 
importantly, improve the affordability of the LIGHT system 
and lower the treatment cost to cancer patients. We

earnestly look forward to leveraging material purchases, 
utilising alternate materials which are less expensive but 
meet performance requirements, manufacturing cycle 
time reduction resulting in reduced labour cost and lead 
time, and improving first-pass yield through thorough 
data analysis and process improvements. A key enabling 
foundation to act on cost, quality and lead times is through 
implementing lean manufacturing coupled with six sigma 
and statistical process control, which involves reducing 
waste, eliminating variations, and maximising the ratio of 
value-added activities versus non-value-added activities. 
 
We are also addressing the need to increase capacity. We 
have already identified the maximum capacity per our key 
supply chain partners based on various market demand 
scenarios. Further to a very positive market demand, 
we have strategically established various deployment 
scenarios at various geographic locations. This strategy 
also includes leveraging our existing staff’s expertise with 
local clinical site personnel. We look forward to our next 
challenge once we complete the first system deployment 
to help improve lives through democratising cancer 
treatment with a much more affordable LIGHT system.
 
How are you working with your suppliers to deal 
with Covid-19, Brexit and other challenges?
Brexit has certainly been a logistical challenge. With no 
clear advanced prescriptions from EU and UK, we incurred 
unexpected or unnecessary shipping delays at the UK border 
as well as additional costs related to custom duties. As time 
progressed, more shipping lead times were added to the 
overall delivery contract and program management processes. 
We have also had to contract custom brokers as necessary 
to ensure reliable custom clearance and transportation of our 
goods. Combination of these two categorical actions have 
now virtually negated shipping delays. 
 
COVID-19, during the last two years, have compounded 
the complexity of our endeavour. Nevertheless, I am proud 
of the achievements made by our staff and our supply 
chain partners. Though the temporary shutdown due to 
COVID-19 caused start-up delays, the team have quickly 
demonstrated immense improvements as momentum 
progressed. To ensure continual operation once the very 
strict shutdown was lifted, we implemented COVID-19 
protocol policy and procedures to ensure the utmost safety 
of our staff. We applied recommended Personnel Protective 
Equipment coupled with sanitisers and tests on a daily basis 
to ensure zero infection at our workplace. Nevertheless, we 
had to deal with the residual impacts of the shutdown at our 
supply chain partners. They too experienced raw material 
shortages, personnel shortages, production capacity 
significantly below pre-COVID which led to delayed receipt 
of vital components. Nonetheless, we creatively assessed 
how to minimally impact the program critical path.

What is needed for market authorisation?
Our LIGHT medical device is subject to extensive 
regulation by numerous agencies, such as the FDA 
in the US or the MHRA in the UK. To varying degrees, 
each of the agencies requires us to comply with laws 
and regulations governing the development, testing, 
manufacturing, labelling, approval, marketing, reporting, 
record keeping, tracking, etc. Our regulatory strategy is 
also shaped by environmental health and safety laws and 
regulations worldwide.
To be distributed in the US, our LIGHT product must 
receive a 510(k) clearance from the FDA. 510(k) is a 
process that requires us to demonstrate that our system 
is substantially equivalent to a legally marketed medical 
device in the field we operate. In the EU, LIGHT must carry 
a Conformité Européenne ("CE") mark indicating that 
it conforms to the European Medical Device Regulation 
as well as the associated enforced EU guidelines and 
essential conformity standards. Upon its CE marking, it 
can be marketed in any EU member state.
Thankfully, the approval of medical devices such as our 
LIGHT system in both the EU and the US share many 
similarities. To obtain certification, our product must meet 
minimum standards of performance, safety and quality 
as well as comply with one or more of a selection of 
conformity assessment routes, which depends on the 
classification of our product. 
What is the classification of your LIGHT product 
and how relevant is this?
In the EU, the LIGHT system – as a radiotherapy 
equipment – is a class IIb medical device. It is positioned 
in the proton therapy market that has a long history 
of treating patients. The level of evidence required 
for approval is largely focused on demonstrating that 
LIGHT is safe and performs as expected. We must also 
demonstrate the effectiveness of LIGHT by making our 
system available for the entire treatment course over more 
or less 25 consecutive irradiation days and by ensuring 
the necessary up-time requirements. 
In EU and UK, we must perform a Clinical Investigation Plan 
to receive our conformity approval, the CE in EU and the UK-
CA in UK. This comes from the fact that our Class IIb medical 
device differs from the existing Proton therapy systems

in the way the energy of the protons used for treatment is 
electronically modified without the need to use degraders for 
energy changes between 70 MeV and 230 MeV.
In the US, our LIGHT System is also a class II device. In 
China it is a class III device as any other proton therapy 
equipment. While clinical trials are necessary in China – as 
for any other proton therapy equipment – this is not the case 
in the US since we follow the similar equivalence route. 
Which evidence do you have to provide?
Following the new Medical Device Regulations ("MDR"), 
we must meet two requirements: the submission of our 
technical file and the demonstration that we can operate to 
a high standard of quality through a Quality Management 
System. The latter is evidenced through our ISO 13485 
certification, which is regularly audited and re-validated. 
The former must contain sufficient effectiveness, safety, 
and quality data, in particular the verification and validation 
test results, along with traceability back to clinical user 
needs, product requirements, and design specifications. 
Verification, validation, traceability, requirements, 
specifications, etc. Tell us more…
Verification and validation – also called V&V – are critical 
activities that confirm that LIGHT as the "contracted for" 
product provides the required operational capability. The 
validation is the process by which we prove that our product 
works for the end-user as intended. Therefore, the user 
needs must be broken down into product requirements and 
design specifications to design and build the right product. 
Validation testing is needed to prove that our product, as 
built, operates according to the users’ expectations under 
the conditions where they intend to use it. Verification, on 
the other hand, is the process aimed at confirming that the 
specified requirements have been fulfilled. Put it simply, 
we must demonstrate that the product we built is the 
product we said we would build.
In that context, traceability is important because it is the 
link between user needs and test cases. A trace matrix 
provides part of the V&V evidence that the certification 
agencies require.
Is this a difficult process?
No, it is not. Personally, I have been through 13 certification 
processes with the US-FDA, 13 certification processes 
with the European Notified Body, two certification 
processes with the Chinese Food and Drug Administration 
("NMPA") and other processes in other geographic areas. 
Therefore, my confidence comes from the fact that the 
process of getting the conformity approval of LIGHT is not 
that different, whilst we must remember that regulators 
can always ask for additional data. 
A critical success in our regulatory strategy is to ensure we 
do not leave any stone unturned. Our regulatory plan follows 
a very thorough process that requires the right tool and the 
right mindset across the whole organisation. It is a time-
consuming activity because each of the subcomponents 
and components that make up the LIGHT product must 
be verified, integrated, and tested. This operational testing 
is the venue that gathers data to validate that the ultimate 
product satisfies the required operational capabilities.
If you consider the validation activities as an example, we must 
undertake various activities ranging from the comparison 
of LIGHT against the equivalent equipment performing for 
similar purposes, the simulation of functionalities through 
mathematical modelling, the testing of the final design to 
prove the system operates as defined in the user needs, the 
preparation, implementation and reporting of test plan, test 
cases, test execution records which must be documented 
and maintained as a part of design records. So, validation, 
in its entirety, is not the result of a single activity, but the 
collection of results from all validation activities.
You are talking about having the “right mindset”. 
Can you explain this further?
The product certification is an important milestone in the 
journey of a company, but this is not the end of the road. 
On the contrary, this is rather the beginning… To go far 
and have a long product life cycle, quality – one of our 
key corporate values – must be embedded in everything 
we do. This is based on the premise that no single tool, 
test, or person can guarantee quality. For quality to be a 
solid part of our culture, everyone needs to support and 
contribute to it – from management and sales teams 
to developers, architects, and product managers. At 
Advanced Oncotherapy, we have this mindset, a pre-
requisite for a sustainable success. 
Who are your points of contact to ensure your 
regulatory strategy does not result in surprises 
and delays?
In Europe, our approval application must be reviewed by a 
Notified Body which is authorised by the health agency. Its 
role is to assess and assure conformity with requirements 
of the relevant EU directive. Notified Bodies are accredited 
private companies that contract with manufacturers such 
as ourselves to supply product certifications for a fee. 
At the highest level of the European Commission Medical 
device 
regulatory 
organisation, 
the 
Medical 
Device 
Coordination Group ("MDCG") is the instancy delivering the 
accreditation to the Notified Bodies and it is also the authority 
defining special enforced guidelines. The Proton Therapy 
medical equipment is classified as class IIb for which a 
mechanism for scrutiny of conformity assessments is in place. 
This is applied for certain class III and class IIb devices. 
Because of this applicable mechanism for scrutiny of 
conformity assessments, once our Notified Body agrees 
that our product meets requirements for conformity, it must 
submit its report to the EU-MDCG for approval and only 
after this it can issue a certificate of approval for conformity 
requirements of the Medical Device Regulation. Once 
we get this certificate, we are then authorised to issue a

CE mark conformity certificate, and LIGHT can then be 
marketed in the EU member states and delivered to our 
clinical customers for clinical use.
In the US, the counterpart is the FDA. As part of our pre-
submission process – called Q-Sub process – the FDA 
has and continues to provide constructive comments on 
our filing strategy. This Q-Sub process applies because 
LIGHT is considered as an innovative proton therapy 
system. The FDA favours an interactive dialogue through 
the development process which aims to facilitate the 
approval once our dossier is submitted.
What is driving you?
I am very proud to be part of this journey. Playing a role 
in offering physicians the opportunity to treat tumours in 
organs that cannot be immobilised during treatment and 
improve patient access to proton therapy treatments is 
extremely rewarding. 
The LIGHT system is a world first for the advanced 
treatment of cancers integrating imaging equipment 
combined with a pulsed proton beam that will be able to 
modulate the energy and the protons current of the beam 
in real time. After the introduction of the cyclotron-based 
proton therapy systems in the 50s, the new generation of 
proton therapy systems is almost there now! 
Throughout my career, I have seen the enormous 
challenges of using and getting approved cyclotrons. 
Their proton beams must be degraded with poorly efficient 
transmission absorbers, which is generating a significant 
number of neutrons in the bunker, further impacting 
the equipment and the building as well as creating 
decommissioning problems. I am a believer that we all 
have a duty to protect our planet. So, introducing LIGHT 
to the market is a major step forward in this commitment. I 
also find the opportunity to manufacture LIGHT in a high-
volume production setting particularly compelling, thanks 
to its design that largely relies on very pure copper units. 
I see this as a fundamental difference against cyclotrons 
which require a large amount of steel and necessitate 
magnetic field mapping and correction of steel defects 
during each production cycle. 
Put it simply, what is keeping my passion intact after all

ANNUAL REPORT 2021

The LIGHT system is the only solution that integrates the delivery 
of protons with a state-of-the-art imaging system directly in the 
treatment room; it offers significant advantages over legacy 
systems, including smaller footprint, modular design, ease of 
installation, fast electronic control of the proton beam and energy, 
significant cost saving for customers. Given the modularity of 
LIGHT, a unique feature in proton therapy, the package provided 
to customers is also complemented with tailor-made financing 
solutions. This is the basis of the partnership between Kineo and 
the Company, a major source of differentiation and a key stepping-
stone in accelerating the market adoption.
Commercial partnerships are built upon a participation of the 
Company to the operations of the clinical centre through a 
risk-reward strategy. This aligns interest, provides Advanced 
Oncotherapy with unique insights in terms of future engineering 
and clinical developments, increases responsiveness, and 
provides a long-term source of revenues for the Company. Further 
details can be found on pages 69 and 70.
Given the investment needed for building proton therapy centres, 
long-term servicing contracts (typically 20 years +) are the norm. 
This must be accompanied with a clear understanding of the 
market dynamics and the cancer centres aspirations. This must 
consider the long-term need to integrate and optimise the proton 
therapy operations with the other cancer services of the operators 
as they seek to continually differentiate their product offering.
Staying at the forefront of innovation is predicated on the Company’s 
ability to leverage the versatility of the LIGHT platform and deploy 
the series of future technical upgrades which have already been 
identified, such as FLASH LIGHT. This is done through scientific 
partnerships as well as clear internal processes with well-defined 
KPIs. This forward-thinking approach is essential when planning 
and installing new LIGHT systems, so that customers always 
benefit from the latest technological advancements.

SECTION 
172 STATEMENT
Effective engagement with our key stakeholders 
and managing our impact on stakeholder 
interests
Effective engagement with our stakeholders is critical 
to the business. It helps us to appreciate the impact 
our decisions have on stakeholder interests and better 
understand their needs and concerns. It strengthens our 
relationship with them, is an ongoing part of the operational 
management and governance of the Company and is key 
for long-term sustainable growth.
As required by Section 172 of the Companies Act 2006, the 
Directors must act in the way they consider, in good faith, 
would most likely promote the success of the Company for 
the benefit of its shareholders. In so doing, the Directors 
must have regards, amongst other matters, to the:
•	
Likely consequences of any decision in the long-term;
•	
Interests of the Company’s employees;
•	
Need to foster the Company’s business relationships 
with suppliers, customers and others;
•	
Impact of the Company’s actions on the community 
and environment;
•	
Desirability of the Company maintaining a reputation 
for high standards of business conduct;
•	
Need to act fairly between members of the Company.
Our Stakeholders
Patients
Our purpose is clear: help patients afford access to the 
latest technology in the cancer treatment and proton 
therapy. Through the LIGHT system and services, the 
Group is looking to provide large and small health practices 
with the flexibility to equip themselves with what the 
Company thinks is the best technology, and at the same 
time decreases the cost of a proton therapy treatment. 
Because patients are at the heart of everything we do and 
because their needs are fundamental to our success, we 
consult with Key Opinion Leaders regularly and conduct 
market research to help us with patient insights.
Employees
We are a people-centric, equal opportunity business 
driven by our values and – as of December 2021 – employ 
174 people, aiming to develop them to the best of their 
abilities whilst maintaining their safety and well-being. The 
Board, and especially the Remuneration Committee, have 
also had particular regards to employees as they reviewed 
and revised the long-term incentive arrangements as part 
of its strategy to attract, retain and motivate employees 
in order to deliver value for shareholders. These actions 
were consistent with the Board’s commitment to investing 
in and responsibly rewarding employees as they deliver 
the Company’s strategy.
Regulators
Safety and quality are two of our four key values. We 
are committed to do the right thing to ensure the safety 
of patients, our users, and our staff. We focus on patient 
outcomes, reliability and consistency. To do so, we 
engage with competent authorities and our Notified Body; 
this ensures we operate within the appropriate regulatory 
and legal framework, further accelerating our plan for the 
certification of the LIGHT system in the targeted markets.
Safety is also linked to data protection; our cyber strategy 
is constantly evolving to anticipate and respond to the 
advances being made in the technologies we use and the 
threats we face.
Commercial partners
The Board places great emphasis on selecting the most 
suitable commercial partners who share the Company’s 
vision and do not accept proton therapy is reserved to 
a minority of patients. The Board keeps itself aware of 
changes in the industry by fostering existing relationships 
and through extensive networking. Furthermore, the 
Company has appointed specialist advisers – in support to 
its commercial team – to identify and target the right potential 
partners and facilitate discussions and negotiations.
Supply chain 
Centred on an outsourced manufacturing model, the 
Company relies on circa 150 third-party suppliers. The 
support of the Group’s supply chain is vital in becoming a 
sustainable business. Our expanded relationship with VDL 
and Cosylab exemplifies the strength of the bond that we 
build with our partners. For enhanced transparency and 
mutual protection in the management of our third-party 
relationships, the Company uses automated purchasing 
and approvals processes, coupled with robust service 
level agreements.
  
Investors
Effective communication with shareholders on strategy 
and governance is critical. The Board naturally considers 
its shareholders to be key stakeholders of the Company 
and is focused upon delivering long-term value for their 
benefit. The Company engages with its shareholders 
and potential investors on a regular basis with meetings 
throughout the year. External strategic communications 
advisors provide further support to manage the 
relationship with investors and analysts and assist with 
market interactions and announcements. The results of 
this investor engagement are reported to the Board to help 
inform our strategy and communications.

ANNUAL REPORT 2021
PRINCIPAL RISKS AND 
RISK MANAGEMENT 
At Advanced Oncotherapy, we adopt a sensible risk-
taking approach, which cannot be defined by one figure 
or formula. We set our risk boundaries to align with our 
strategy, values, policies and corporate directives. Our 
approach depends on the type of risks, as follows:
•	
Strategic risks: Strategic risks are risks that can 
significantly impact the execution of our business 
strategies and our ability to achieve our objectives. 
We include external and emerging risks in this risk 
area, such as industry shifts and technological 
shifts. These risks can all impact our business 
negatively long term but often also create business 
opportunities if managed well. Our approach to 
managing these risks differs from other categories as 
it includes evaluation of which strategic risks to take 
and improving the business ability to manage them 
by establishing risk tolerance, predicting the impact 
of possible risks and monitoring key risk indicators.
•	
Financial risks: The Company is exposed to 
multiple financial risks such as macroeconomic risks 
and execution risks associated with the Company’s 
AVO's risk appetite
financing plan. The Board of Directors establishes the 
principles for the Group’s financial risk management, 
which comprises guidelines, objectives, and limits for 
financial management as well as the management of 
financial risks within the Group.
•	
Business risks: In this risk area we include operational 
and commercial risks. These types of risks can often 
impact the financial performance of the business 
negatively or can have a negative reputational impact 
on Company. Examples are sustainability risks, such 
as compliance risks, and operational risks, such as 
IT failures as well as talent attraction and retention. 
The approach to managing these risks is through 
active prevention and by designing and implementing 
mitigation actions and controls.
We have implemented a risk management cycle whereby 
all key risks are identified, discussed, assessed and 
monitored. In 2021, we identified approximately 136 
risks. They were classified and consolidated using a 
quantification method to weigh potential impacts and 
likelihoods of the various risks.

ADVANCED ONCOTHERAPY PLC 
Introduction
Product and market positioning
Business delivery   
The successful execution of the financing strategy of 
the Company depends on a variety of factors and risks 
Description: The financial risks faced by the Company include 
the ability to cover working capital needs, raise sufficient funds 
to support the Company through to profitability and failure to 
secure further contracts. The financing requirements of the 
Group also depend on numerous factors, including the rate of 
market acceptance of the LIGHT System and the ability to attract 
and retain customers. This means the Company often faces 
uncertainties in its cash flow till the installed base is large enough. 
Mitigation: The Company has successfully advanced the 
LIGHT technology for several years, including securing 
research collaborations and sale contracts. The Group 
employs tight cost controls across the business and has 
raised £146 million between December 2017 and December 
2021. It continually monitors opportunities which provide 
financing flexibility to deliver on its strategic priorities. The 
Company also prepares short term and medium cash 
flows to ensure that the business has adequate funding to 
execute its business strategy.
Exposure to international markets and risks
Description: The Company’s strategy is focused on 
marketing LIGHT in various countries. Its international 
operations are therefore subject to a variety of risks, 
including difficulties in staffing and managing foreign and 
geographically dispersed operations, differing regulatory 
requirements for obtaining clearances or approvals to 
market LIGHT; fluctuations in foreign currency exchange 
rates; imposition of limitations on production, sale or export 
of proton therapy systems in foreign countries, etc.
The cancer market and proton therapy industry are 
subject to rapid changes and the light technology 
could be replicated
Description: The industry is characterised by rapid 
technological changes, new product introductions and 
enhancements and evolving industry standards, all of which 
could impact the commercial success of the LIGHT System. 
New alternative cancer treatment modalities could also be 
introduced, which would hinder the commercial prospects 
of the Company. A competitor could attempt to replicate a 
linear proton accelerator technology for medical use. 
Mitigation: The Company understands that future success will 
depend on its ability to keep pace with the evolving needs of 
its customers and the medical profession on a timely and cost-
effective basis and to pursue new market opportunities that 
develop as a result of technological and scientific advances. 
To keep pace with evolving standards of care, the Company 
has identified new opportunities and established an innovation 
roadmap, which is expected to enhance the product technology 
offering and develop new product features. An increasing 
number of innovations could be used in combination with 
radiation, such as immunotherapy. Such innovations are 
therefore perceived as an opportunity rather than a threat.
The development and introduction of a linear-based turn-key 
Mitigation: The Company’s structure across the UK, 
Europe and the US creates a diversified base and a natural 
“hedge”. Furthermore, and in the context of exchange rates 
fluctuations, the Group does not issue or use financial 
instruments of a speculative nature and the Group’s treasury 
function does not act as a profit centre. The Company has a 
strong commitment to anti-corruption, anti-bribery and ethical 
behaviours, as reflected in its current policies. All policies are 
regularly reviewed, and compliance training is given. Each 
employee is required to sign an agreement to confirm that 
they understand and will comply with the policies.
Macro-economic or business instability
Description: Geopolitical issues and continuing concerns 
over Covid-19 have contributed to volatility for the global 
economy. If the economic climate does not improve, the 
operations of the Company, its customers and suppliers 
could be adversely affected. Additionally, the instability 
has resulted in diminished liquidity and high market 
volatility, which could impair the ability of the Company to 
access capital if required. In the event of further economic 
slowdown, investment in medical device companies may 
also experience a corresponding slowdown.
Mitigation: The Company mitigates this risk by having an 
increasingly broad offering, service, and geographical range, 
limiting the impact of events in any single territory. The Group 
also considers political risk when assessing new contracts or 
product acquisitions. The Group will continue to monitor the 
Brexit and Covid-19 situations and assess the impact on the 
Group’s ability to access capital in the UK. 
system requires a combination of technology and specialised 
skills which is hard to replicate. The Group's patent portfolio, 
the know-how and the diversity of the required skills which are 
complex to develop constitute a further barrier for new entrants.
The market for proton therapy equipment is characterised 
by intense competition 
Description: The Company faces competition from 
numerous companies, many of whom have large 
resources, which may make it more difficult for LIGHT to 
achieve significant market penetration. Competitors may be 
better positioned to spend more aggressively on marketing, 
sales, intellectual property and other product initiatives and 
research and development activities.
Mitigation: The Company strives to be a trusted partner to 
customers. To do so, it relies on a business model uniquely 
designed to leverage the features of LIGHT and focused 
on aligning interests with customers. The Company 
has established the key foundations of a new financing 
approach with Kineo; this plays a crucial role in removing 
the upfront costs of acquiring and installing LIGHT by 
converting CapEx to OpEx; in addition, this reduces the 
reliance on the Company’s balance sheet, hence further 
unlocking significant additional upside and accelerating

ANNUAL REPORT 2021
PRINCIPAL RISKS AND 
RISK MANAGEMENT_Continued
The launch of light and its market acceptance are 
subject to risks
Description: LIGHT is subject to market clearance and 
there is no certainty that it may receive market acceptance 
from regulators. If there is any delays to obtain market 
clearance, the Company may require further working 
capital. This means that it faces uncertainties in its cash 
flow until the installed base is large enough. 
Mitigation: The research and development team – whose 
outputs rely on a validated technology (LIBO) – has identified 
the main technological risks and performed focused studies to 
ensure the underlying concepts remain viable with improved 
clinical outcomes. The Company’s technology strategy 
is also regularly reviewed to ensure that the systems it 
operates across the Company support its strategic direction. 
The Directors shall seek to minimise the risk of delays by 
careful management of projects by working with accredited 
experts, suppliers and building companies. 
The Company operates in an industry characterised by 
strict legal, regulatory and compliance requirements 
Description: Changes to regulation as a result of Brexit, 
evolving political landscapes and more stringent norms in 
the medical industry could have an impact on the approval 
process of the LIGHT System and the Company’s ability 
to sell and install future machines. Failure to proactively 
identify and comply with industry laws and medical 
regulatory aspects could result in fines, penalties, business 
disruption, reduced revenue, and/or potential exclusion 
from tender processes. 
Mitigation: The Company proactively monitors changes in 
regulation and legislation and ensures that all obligations are 
complied with, and forthcoming legislation is appropriately 
planned for. It ensures that employees understand legal 
risks and how to comply via anti-bribery and corruption 
policies, reinforced by the Company’s Code of Conduct. 
Furthermore, targeted audit reviews are undertaken to 
ensure policies and training are embedded. When required, 
external advice is also taken, particularly for situation where 
capabilities are not available in-house. 
The commercial prospects of the Company may 
fluctuate 
Description: The Company relies solely on the 
commercialisation of its LIGHT System to generate revenue. 
Any factor materially adversely affecting the Company’s 
ability to market and sell its LIGHT System, its pricing 
and demand would have a material adverse effect on our 
financial condition and results of operations. Demand may 
not increase as quickly as planned. Sales cycles in proton 
therapy tend to be long, which may contribute to substantial 
fluctuations in the operating and financial results.
Mitigation: The Company is dedicated to understanding 
the requirements of customers and pre-empting their 
needs. As a result, it is seeking feedback from existing and 
prospective customers, which is key to accelerate their 
decision process and ensuring customers’ satisfaction. 
The initiatives to provide vendor financing and leasing 
arrangements to customers as well as developing new 
product features such as FLASH and minibeams are 
consistent with the Company’s commitment of building a 
flexible customer-centric model.
The Company has a limited history of assembling light 
systems in commercial quantities	
Description: The Company has only a limited history of 
assembling and installing the LIGHT System and, as a 
result, it may have difficulty delivering LIGHT in sufficient 
quantities in a timely manner or may not have enough data 
to accurately predict future component demand. Following 
market disruptions post Brexit and Covid-19, the Company 
experienced delays in obtaining components from suppliers, 
which may delay its ability to assemble future systems. 
Accordingly, the Company may encounter difficulties in 
scaling up production, including problems with quality control 
and assurance, component supply shortages, increased 
costs, and shortages of qualified personnel. 
Mitigation: The Company outsources production to 
trusted manufacturing and global partners which the Group 
assesses regularly. The Group also has industry-leading 
quality management systems and audits supply partners 
where appropriate. The Group also intends to maintain 
appropriate stock levels of its key parts of LIGHT, with a focus 
on long-lead items, allowing to better serve clients’ needs. 
Hiring and retaining talents is a necessity but is not 
without risks
Description: The Company’s success depends on the 
skills, experience and performance of key members of the 
senior management team. The individual and collective 
efforts of these employees are important as the Company 
continues to develop its LIGHT System, and as it expands 
its commercial activities. The loss or incapacity of existing 
members of the executive management team could 
adversely affect the Company’s operations if the Company 
experiences difficulties in hiring qualified successors. 
Success also depends on the Company’s ability to 
attract and retain highly skilled engineers, scientists, and 
technicians. The Company may not be able to attract 
or retain qualified managers, engineers, scientists, and 
technicians in the future due to the competition for qualified 
personnel among medical device businesses,
Mitigation: The Company seeks to attract and retain high 
quality personnel by providing employees with a rewarding 
package of salary and benefits which include share option 
scheme, private medical insurance, and flexible working. 
Maintaining a high level of employee satisfaction and 
engagement is also key. This is done through an investment 
in appropriate quality resources and infrastructure to 
support the staff and efficient working practices. This 
includes focus on providing learning and development 
opportunities, training, and career paths to enable people 
to fulfil their potential.

Introduction
Product and market positioning
Business delivery 
Reliance on information technology systems and 
infrastructure is impacting how the Company operates
Description: The Company’s success depends on 
its infrastructure and set-up as well as its information 
technology systems. The LIGHT System is also equipped 
with the latest generation of propriety software packages 
developed by third-parties. Information technology systems 
are vulnerable to damage from a variety of sources, 
including network failures, malicious human acts and 
natural disasters. Moreover, despite network security and 
back-up measures, some of the servers are potentially 
vulnerable to physical or electronic break-ins, computer 
viruses and similar disruptive problems. 
Mitigation: The Company has taken precautionary 
measures to prevent unanticipated problems, including the 
implementation of a system of data storage, offsite backup 
and monitoring of key coding and modelling data. Following 
the disruption caused by Covid-19 and the necessary need 
to support remote operations, the Company has invested 
in servers dedicated to highspeed computation which has 
significantly reduced the time required to run operations 
and reduce risks.
Reliance on third parties requires a carefull risk 
assessment
Description: The Company relies on arrangement with 
third-parties for manufacturing components of the LIGHT 
System. As a result, the Company is subject to disruptions, 
delays, and potential increased costs due to factors beyond 
its control. Any failure to deliver, install or service future 
LIGHT Systems in a timely manner may damage the 
Company’s reputation, with the risk of losing customers.
Mitigation: Wherever possible, the Company seeks to have 
duplicate suppliers to lessen the reliance on a particular 
vendor. Arrangements with third-parties also encompass 
an array of protective clauses in favour of the Company.

ANNUAL REPORT 2021
The Directors recognise the importance of 
sound corporate governance and are committed 
to maintaining high standards of corporate 
governance.
Introduction
The Board of the Company is collectively accountable 
to the Company’s shareholders for good corporate 
governance, with the Chairman taking a lead on corporate 
governance matters. Accordingly, and in accordance with 
the London Stock Exchange’s requirement for all AIM-
quoted companies to comply with a recognised corporate 
governance code, the Board of Directors of the Company 
adopted the Quoted Companies Alliance (QCA) Corporate 
Governance Code (Code). The Board considered that the 
Code provides the Company with the framework to help 
ensure that a strong level of governance is maintained, 
enabling the Company to embed the governance culture 
that exists within the organisation as part of building a 
successful and sustainable business for all its stakeholders. 
The Code is constructed around 10 principles, taking key 
elements of good governance and applying them in a manner 
which is workable for the needs of a growing company in 
pursuit of medium to long-term value creation for shareholders. 
The Board is of the unanimous opinion that the Company 
complies with the Code and any divergence from the Code 
are, in the circumstances, reasonable, appropriate and in the 
best interests of the stakeholders of the Company as a whole.
This statement sets out how we currently comply with the 
provisions of the QCA Code and – when relevant – the 
reasons for any departures from it. A full copy of the QCA 
Code is available from the QCA’s website: www.theqca.com 
The QCA Code contains the following 10 principles:
•	
Principle 1 – establish a strategy and business model 
which promote long-term value for shareholders;
•	
Principle 2 – seek to understand and meet 
shareholder needs and expectations;
•	
Principle 3 – take into account wider stakeholder and 
social responsibilities and their implications for long-
term success;
•	
Principle 4 – embed effective risk management, 
considering 
both 
opportunities 
and 
threats, 
throughout the organisation;
•	
Principle 5 – maintain the board as a well-functioning, 
balanced team led by the chair;
•	
Principle 6 – ensure that between them the Directors 
have the necessary up-to-date experience, skills and 
capabilities;
•	
Principle 7 – evaluate board performance based on 
clear and relevant objectives, seeking continuous 
improvement;
•	
Principle 8 – promote a corporate culture that is 
based on ethical values and behaviours;
•	
Principle 9 – maintain governance structures and 
processes that are fit for purpose and support good 
decision-making by the Board;
•	
Principle 10 – communicate how the company is 
governed and is performing by maintaining a dialogue 
with shareholders and other relevant stakeholders.
Principle 1 – Establish a strategy and business 
model which promote long-term value for 
shareholders 
The Company’s ambition and growth prospects are 
underpinned by a vast unmet medical need, the development 
of a proton-based medical system that has been tailored

to meet the needs of physicians, an innovative business 
model and a lean and robust infrastructure to meet future 
demand and introduce future product upgrades. 
The Company’s vision is to democratise proton therapy, 
which – as explained within the previous Strategic Report 
section, on pages 13 and 14 – is driven through five 
strategic priorities:
•	
solve customers’ need by introducing a turn-key 
solution that delivers the best outcome for patients 
whilst making treatments more affordable;
•	
support customers through long-term servicing 
contracts;
•	
scale the Company’s infrastructure to reduce future 
cost and lead times and increase throughput, the 
foundation for delivering a fast-growing pipeline; 
•	
share a common vision of doing good and well with 
all stakeholders, including customers and suppliers, 
in the spirit of aligning interest in the long-term; 
•	
sustain the Company’s competitive advantages through 
innovation, investment in talents and a commitment to 
make a positive impact on society and environment.
Its business model is further detailed on pages 67 and 68. 
The Company operates in a highly regulated sector, and 
this is reflected in the principal risks and uncertainties that 
may affect the business, which are set out in more detail 
on pages 73 to 76.
Principle 2 – Seek to understand and meet 
shareholder needs and expectations
The Board of the Company endeavours to engage in clear 
and consistent dialogue with both existing and potential 
shareholders to assess their needs, expectations, and any 
concerns they may have as well as ensure that the Company’s 
strategy, business model and progress are clearly understood. 
This active communication is maintained through a planned 
programme of investor relations which includes formal 
presentations, meetings with investors and analysts on 
a regular basis. Regular communication also takes place 
through the Company’s annual report and website, which 
contain up-to-date information on the Group’s activities. 
This is complemented with the use of a Regulatory 
Information Service and social media. The Company has 
established an email alert service on its website to which 
shareholders and other interested parties can subscribe 
to receive company announcements as and when they 
wish 
(www.avoplc.com/en-gb/Investors/Investor-Alert-
Service). There is also a designated email address for 
shareholder liaison – ir@advancedoncotherapy.com 
– and all contact details are included on the investor 
relations website.
The Board also recognises that the Annual General Meeting 
(AGM) provides an opportunity to meet shareholders and 
it values their feedback. All shareholders are given the 
opportunity to ask questions and raise issues; this can be 
done formally during the meeting or in writing prior to the 
meeting. The Notice of the AGM is sent to shareholders 
at least 21 days before the date of the meeting and all 
Directors routinely attend the AGM and are available to 
answer questions raised by shareholders.
Copies of the annual report (which includes the notice of 
AGM) and the interim report are available to all shareholders 
and can be downloaded from the investors’ section https://
www.avoplc.com/en-gb/Investors/Company-Documents. 
Alternatively, they are available on request by writing to 
the Company Secretary at Henry.Clarke@avo-adam.
com. Other information for shareholders – including the 
results of the resolutions of the AGM results and the share 
price performance of the Company – is also provided on 
the Group’s website.
Principle 3 – Take into account wider stakeholder 
and social responsibilities and their implications 
for long-term success
The Company recognises that the introduction of LIGHT 
and more broadly the implementation of innovative 
health solutions for cancer patients are more likely to 
be successful when a broad range of stakeholders and 
decision-makers are part of the process. Involving medical, 
technical, and other experts to ensure that all aspects of 
the patient pathway are covered from the outset creates 
ownership and contributes to the long-term success for 
the Company as a whole. Therefore, the Board places 
utmost importance on the feedback from all stakeholders, 
which is key to frame and adjust the Company’s strategy. 
The Company is also aware of its corporate social and 
environmental responsibilities. It is the Group’s policy and 
practice to comply with health, safety and environmental 
regulations and the requirements of the countries in which it 
operates to protect its employees, partners, assets, and the 
environment. A range of processes and systems have also 
been put in place to ensure that there is close oversight and 
contact with these key resources and relationships. This 
commitment is evidenced and underpinned by the vision 
and values of the Company, described in pages 7 and 8 of 
the Strategic Report. The Board is committed to harness 
this mindset to bring the right stakeholders together and 
connect healthcare providers, patients and information 
systems in a way that is scalable and sustainable. It 
remains grounded in the Company’s purpose of delivering 
quality, patient-centred care and the delivery of better 
outcome for patients. How the Board seeks to engage with 
all stakeholders and ascertain their feedback is set out in 
our section 172 statement on pages 71 and 72.
Principle 4 – Embed effective risk management, 
considering both opportunities and threats, 
throughout the organisation 
Risk assessment and evaluation is an essential part of 
the Company’s planning and control system. This is also 
critical to safeguard the Company’s assets and enable it 
to meet its strategic objectives. The Company operates in

ANNUAL REPORT 2021
a highly regulated environment and as such is necessarily 
subject to stringent medical norms and regulation as well 
a rigorous health and safety regime. 
The Board has delegated the responsibility for reviewing 
and monitoring the risk management systems to the Audit 
Committee, which works closely with the management and 
reports back to the Board. Any such system of financial and 
operational controls can provide reasonable, but not absolute 
assurance, against material misstatement or loss. The Board 
considers that the internal controls in place are appropriate for 
the size, complexity, and risk profile of the Company. The Group 
receives regular feedback from its external auditors on the 
state of its risk management and internal controls, monitoring 
and reporting to the Board on the Groups performance. 
The Company maintains a risk register which is reviewed 
regularly, and which covers a variety of financial, operational, 
economic, and regulatory uncertainties. This register allows 
the Board to appraise external and internal threats to the 
business and to plan and mitigate accordingly. Principal 
risks and uncertainties that may affect the business are 
set out in more detail on pages 73 to 76. Notes 1  and 19 
within the Financial Report also expands on the Company’s 
exposure to risk and the steps to control and manage 
exposure to risk. The Board has a conservative approach 
to financial risk management and the Group does not use 
any speculative or non-basic financial instruments.
The Company has adopted a Code of Conduct which 
Further details on the governance structure are set out at 
Principle 9. 
Independence
The Directors are mindful that a balance between 
Executive and independent Non-Executive Directors 
should be maintained to facilitate impartial and equitable 
decision making. 
The individual members of the Board have equal 
sets out the standards that it expects all employees and 
representatives of the Company to meet. It is the Board’s 
view that encouraging these high working standards helps 
to mitigate against risks arising in the day-to-day activities.
BNF Insurance Services in the UK and Kessler & Co SA in 
Switzerland provided insurance services to the Company. 
Under their guidance, the Company has put in place a scheme 
of insurance which reflects both the current and medium-term 
needs of the business and this is continually monitored through 
periodic reviews with our advisers and our underwriters.
Principle 5 – Maintain the board as a well-
functioning, balanced team led by the chair
The Board
The Board currently comprises of six Non-Executive 
Directors and three Executive Directors. The biographies 
on pages 81 and 82 include further disclosures in relation 
to the Directors, their relevant experience, skills and 
personal qualities and capabilities. 
Duties
The Board is collectively responsible for the success of 
Advanced Oncotherapy and provides entrepreneurial 
leadership of the Company within the framework of effective 
controls, which enable tasks to be assessed and managed. 
It sets out the Company’s values and standards and ensures 
that its obligations to shareholders and other stakeholders 
are understood and met. In accordance with the Companies 
Act 2006, the Board complies with the following:
responsibility for the overall stewardship, management, 
and performance of the Group and for the approval of its 
long-term objectives and strategic plans. 
Whilst the Board recognises that having an Executive 
Chairman is not considered best practice under the QCA 
Code, it feels that the commitment, expertise, industry 
connections and enthusiasm the Executive Chairman 
brings to the role offset this. The role of the Chairman is 
reviewed periodically by the Board.

STRATEGIC REPORT
The current division of responsibilities between the 
Executive Chairman and Chief Executive Officer have 
each been agreed by the Board. Dr Michael Sinclair, the 
Executive Chairman, is responsible for the running of the 
Board. Nicolas Serandour, the Chief Executive Officer, has 
executive responsibility for running the Group’s business 
and implementing its strategy. 
All Non-Executive Directors serving at the year-end bring 
an independent judgement. Mrs. Renhua Zhang (Non-
Executive Director) is not considered to be independent 
as she represents a large shareholder, Liquid Harmony. 
The Board does not consider the shareholdings of the 
other Non-Executive Directors as detailed on page 102 
to have any effect on their independence. The Executive 
Chairman and other Non-Executive Directors have other 
directorships, which are not deemed to conflict with the 
business of the Company.
Reasonable care, skill, and diligence
Directors have a duty of reasonable care, skill, and 
diligence. To do so, they take the following into 
consideration in any decision-making process:
•	
the likely consequences of any decision in the long term;
•	
the interests of the Company's employees;
•	
the need to foster the Company's business 
relationships with suppliers, customers and others;
•	
the impact of the Company's operations on the 
community and the environment;
•	
the desirability of the Company maintaining a 
reputation for high standards of business conduct;
•	
the need to act fairly as between members of the 
Company;
Further information on the knowledge, skill and experience 
of Directors can be found on pages 81 and 82.
Time commitment
Each board member commits sufficient time to fulfil their 
duties and obligations to the Board and the Company. 
They attend regular board meetings and join ad-hoc board 
calls and offer availability for consultation when needed. 
The contractual arrangements between the Directors and 
the Company specify the minimum time commitments 
which are considered sufficient for the proper discharge of 
their duties. The time commitment is commensurate with 
the size and complexity of a quoted company. However, in 
exceptional circumstances all board members understand 
the need to commit additional time.
Attendance
The Board met six times in 2021, excluding separate ad-
hoc meetings and calls. Due to COVID-19 restrictions, 
the Board and committees have been restricted in their 
ability to physically meet and have utilised virtual meeting 
rooms to ensure dialogue, challenge and support has 
been provided throughout. The record of each Director’s 
attendance at Board meetings is set out thereafter.
Directors who were unable to attend specific meetings 
reviewed the relevant papers and provided their comments 
to the Executive Chairman of the Board or Committee. 
Any Director who misses a meeting receives, as a matter 
of course, the minutes of that meeting for reference.
Conflicts of interest
To address the provisions of Section 175 of the Companies 
Act 2006 relating to conflicts of interest, the Company’s 
Articles of Association allow the Board to authorise situations 
in which a Director has, or may have, a conflict of interest. 
Directors are required to give notice of any potential situations 
or transactional conflicts that are to be considered at the next 
Board meeting and, if considered appropriate, conflicts are 
authorised. Directors are not permitted to participate in such 
considerations or to vote regarding their own conflicts.
Remuneration
The Board considers and determines the remuneration of 
the Executive and Non-Executive Directors. No Director is 
involved in setting his or her own remuneration.
Principle 6 – Ensure that between them the 
Directors 
have 
the 
necessary

independence, knowledge of the Company’s technology, 
sector experience and professional standing to allow it to 
discharge its duties and responsibilities well. All Directors 
are encouraged to constructively challenge strategy, 
scrutinise performance and use independent judgement 
based on their respective knowledge and experience on 
all matters affecting the business.

QCA Code, the Market Abuse Regulation and other statutory 
and regulatory developments. In that regard, all Directors 
have access to the Company’s NOMAD, Company Secretary, 
lawyers and auditors are able to obtain advice from other 
external bodies as and when required, at the Company’s 
expense. Details of the Company’s advisors can be found on 
the website and on page 151 of the annual report. 
Principle 7 – Evaluate board performance 
based on clear and relevant objectives, seeking 
continuous improvement
The Board seeks to improve the ways in which it interacts, and 
the way information is presented to it. The processes that have 
been put in place allow for a consistent approach to reporting, 
thus aiding analysis by the Board of all matters at hand. 
In May 2021, the Board conducted a Board Effectiveness 
review under the auspices of the Senior Independent 
Director Hans von Celsing and Non-Executive Director 
Lori Cross, assisted by the Company Secretary. The 
Board may utilise the results of the evaluation process 
when considering the adequacy of the composition of the 
Board, to identify any training and development needs and 
for succession planning. Separately to this, the executive 
Chairman and non-Executive Directors regularly meet and 
discuss performance with members of the Executive team.
In the context of evaluating the Board performance and 
aligning this review exercise with the expectations of 
shareholders, each Director stands for re-election at the AGM 
and significant emphasis is placed on new appointments:
•	
Services and re-election – All Executive Directors have 
service agreements with the Group terminable by either 
party upon the minimum notice period being met. The 
notice period is 24 months for Dr. Michael Sinclair and 
Nicolas Serandour and six months for Prof. Steve Myers. 
Non-Executive Directors are initially appointed for a 
three-year term, but their appointment is terminable by 
either party on three months’ written notice. The letters of 
appointment of all Directors are available for inspection at 
the Company's registered office during normal business 
hours. Executive and Non-Executive Directors retire by 
rotation in accordance with the Company’s Articles of 
Association which prescribe that at every Annual General 
Meeting one third of the Directors shall retire from office. 
However, to underline their accountability to shareholders 
and the Board's commitment to appropriate corporate 
governance, each Director will stand for re-election at 
the upcoming AGM. The Board has concluded that each 
Director is eligible for re-election;
•	
New appointments – When a new appointment to 
the Board is made or a removal is being considered, 
thought is given to the skills, knowledge and experience 
that could be of benefit to the Board. In the case of a 
new appointment, a formal process is then undertaken, 
which may involve external recruitment agencies, 
with appropriate consideration being given, regarding 
Executive appointments, to internal and external 
candidates. Before undertaking the appointment of 
a Non-Executive Director, the Executive Chairman 
establishes that the prospective Director can give the 
time and commitment necessary to fulfil his/her duties, 
in terms of availability both to prepare for and attend 
meetings and to discuss matters at other times.
Principle 8 – Promote a corporate culture that is 
based on ethical values and behaviours
The core principle of the Company is clear: to democratise 
proton therapy. As such, ethical values – life, safety, quality 
and innovation – and behaviours are at the heart of what 
each employee and Director does. The Board seeks to 
enshrine such ethical values and behaviours throughout 
the conduct of all of activities of the Company. These 
values – further outlined in pages 7 and 8 – together with 
our commitment to provide a positive impact on society and 
environment – as detailed in pages 11 and 12 – are set out 
in the Company’s policies, working practices and systems. 
The Board leads by example. The Board seeks to:
•	
treat all persons fairly and equitably with a focus on 
openness and well-being, through clearly defined 
parameters of operation;
•	
take the welfare of all employees extremely seriously 
and invest in people;
•	
promote diversity; 
•	
ensure values are embedded in a positive and 
supportive environment through full compliance with 
norms and certification and the implementation of 
clear policies.
Treating all persons fairly and equitably with a focus 
on openness and well-being, through clearly defined 
parameters of operation
In dealing with each of the Company’s principal stakeholders, 
the Board encourages staff to operate in an honest and 
respectful manner; it believes that achieving a common 
awareness across all employees plays a major role in 
maintaining good employee relations. This culture of honesty 
and respect – reflected in the continued support and dedication 
shown by staff to execute the strategic plan – is promoted by 
listening to and actioning feedback given during the ROADMap 
process (performance management conversations), and 
internal HR channels, with immediate attention paid to any 
concerns raised. The Company is continually improving the 
support provided to managers to help ensure that they are 
actively listening and valuing their teams.
Taking the welfare of all employees extremely 
seriously and investing in people
The Company takes the welfare of all its employees 
extremely seriously and continues to invest in its people, 
who are encouraged to develop and grow with the business. 
Advanced Oncotherapy strives to continually improve 
the working environment and benefits of its people. The 
Company's commitment to staff is shown in the significant 
investment made to upgrade facilities and the working

environment. During the Covid-19 pandemic, the Company 
has also increased communication and support to all 
staff with frequent updates about the local situation and 
measures taken to keep everyone safe. The Company has 
invested in the training of the HR team to become mental 
health first aiders to support the increased levels of stress 
and anxiety some are facing in the light of Covid-19. 
Promoting diversity
The Board believes it is crucial for the success of the 
Company to have a diverse workforce comprised of 
individuals with different ideas, strengths, interests, and 
backgrounds. It sees a great benefit in the diversity of 
employees, as this helps the Company to better fulfil the 
wishes and multi-faceted demands of customers around 
the world and provides a higher-performing workplace. 
The Company strives to create an environment where 
all employees are heard and appreciated – regardless 
of gender, nationality, ethnic origin, religion, world view, 
abilities, age, sexual orientation, or identity. 
The Board believes in mixed leadership teams as a 
competitive advantage and driver of success. By the end of 
2021, women made up 38% of the workforce, 22% of those 
being managers and 40% in technical roles. The management 
team is represented by 30% women and 5 nationalities. 
The Group applies fair and equitable employment policies, 
and these ensure that entry into, and progression within, 
the Group is determined solely by the fair application of 
relevant job criteria and by personal ability and competence. 
The Company actively promotes the career development 
of its employees. Full and fair consideration (having regard 
to the person's particular aptitudes and abilities) is given to 
applications for employment and the career development of 
disabled persons. The Group will take all practicable steps 
to ensure that if an employee becomes disabled during the 
time he/she is employed, his/her employment can continue. 
It continues to review both performance and potential as a 
key part of the annual performance management, career 
development and succession planning processes. Diversity 
is at the heart of the Group culture, which is characterised by a 
meritocratic and collaborative ethos. 31 different nationalities 
are represented in the Group as of 31st December 2021.
Ensuring values are embedded in a positive and 
supportive environment through full compliance with 
norms and certification and the implementation of 
clear policies
The commercialisation of the LIGHT system requires the 
business to have a robust quality management system 
which is third-party audited to ISO: 13485 standards. 
Underpinning this quality management system are 
processes to ensure that necessary safeguards are in 
place to ensure the integrity of this system and accordingly 
the quality of the products under development. Further 
information can be found on pages 63 to 65.
Policies are also in place covering key matters such as 
bribery, protection of intellectual property and sensitive 
information, conflicts of interest, whistleblowing. These 
are vigorously enforced and monitored. These are further 
outlined at principle 9.
Principle 9 – Maintain governance structures 
and processes that are fit for purpose and 
support good decision-making by the Board
The Board retains full and effective control over the Company 
and holds regular Board meetings at which financial, 
operational and other reports are considered and where 
appropriate voted upon. It has ultimate accountability for good 
governance and is responsible for monitoring the activities 
of the management team. The Board is responsible for the 
Company’s strategy and key financial and compliance issues. 
 
The Board is satisfied that the Company’s governance 
structures and processes are consistent with its current size 
and complexity. The current structure enables the retention 
of key skill sets within the Company whilst facilitating the 
enhancement of the senior management base and the 
continuing development of the Board and the management 
in line with the QCA Code's key principles. As the Company 
grows, the Directors will ensure that the governance 
framework is reviewed and appropriately updated to support 
the development of the business. The Company continues 
to look at how to best improve its corporate governance; 
and as a fast-growing company Advanced Oncotherapy is 
constantly looking for ways to strengthen its Board, whilst 
ensuring that the business is led by people with the right 
experience, passion, and enthusiasm. 
Key processes and structures in place include the following:
•	
clear segmentation of roles and responsibilities with a 
formal list of matters reserved to the Board’s approval; 
•	
internal control focused on safeguarding the 
Company’s assets;
•	
clear guidelines to support healthy and open debates;
•	
dedicated Board Committees;
•	
share dealing policies;
•	
whistleblowing procedures;
•	
anti-bribery and corruption policies;
•	
appointment of a Company Secretary to support the 
Board and ensure processes are being followed.
Clear segmentation of roles and responsibilities 
with a formal list of matters reserved to the Board’s 
approval Operational and reserved matters
Day-to-day operational decisions are taken initially by 
the Executive Directors, in accordance with the Group’s 
strategy. The Executive Directors are also responsible 
for initiating commercial transactions and approving 
payments, save for those relating to their own employment.
The Board has a formal schedule of matters specifically 
reserved for its approval. These matters are delegated 
to the Board Committees, Executive Directors, executive 
management team and senior management where 
appropriate. The schedule of matters reserved for the 
Board can be found on the website www.avoplc.com. Key

matters include:
•	
reviewing, 
approving 
and 
guiding 
corporate 
strategy, major plans of action, risk appetite and 
policies, annual budgets and business plans; setting 
performance objectives; monitoring, implementation 
and corporate performance; and overseeing major 
capital expenditures, acquisitions and disposals;
•	
monitoring the effectiveness of the Company’s governance 
arrangements and practices, making changes as needed 
to ensure the alignment of the Company’s governance 
framework with current best practices;
•	
ensuring that appointments to the Board or its 
Committees are made in accordance with the 
appropriate governance process;
•	
monitoring and managing potential conflicts of interest 
of management, Board members, shareholders, 
external advisors, and other service providers, 
including misuse of corporate assets and abuse in 
related party transactions; and
•	
overseeing the process of external disclosure and 
communications. The Board is also responsible for all 
other matters of such importance as to be of significance 
to the Group as a whole because of their strategic, 
financial, or reputational implications or consequences.
Internal control focused on safeguarding the 
Company’s assets 
The Board is responsible for ensuring that the Company 
maintains a system of internal financial controls. The 
objective of the system is to safeguard assets, ensure 
proper accounting records are maintained and that the 
financial information used within the business and for 
publication is timely and reliable. Given the size of the 
Group, the Board does not consider it appropriate to have 
its own internal audit function.
Clear guidelines to support healthy and open debates
Guidelines are in place concerning the content, 
presentation, and timely delivery of papers by management 
to Directors for each board meeting so that the Directors 
have enough information to be properly briefed. Where 
issues arise at board meetings, the Executive Chairman 
ensures that all Directors are properly briefed and, when 
necessary, appropriate further enquiries are made. 
Dedicated Board Committees 
There are three Board Committees – Audit, Remuneration 
and Strategic committees (which also cover ESG 
considerations). The roles and responsibilities of each are 
detailed on page 92. The terms of reference of the Audit 
Committee and the Remuneration Committee are set out 
on the Company’s website. All Board Committees report 
back to the Board following a committee meeting.
Share dealing
The Company has established a Group share dealing code 
which complies with all applicable legislation, and which is 
in accordance with the requirements of the Market Abuse 
Regulation which came into effect in 2016. All the Directors 
of the Group understand the importance of compliance with 
the Code. At every Board meeting, Directors are reminded 
whether they are allowed to trade shares of the Company. 
Whistleblowing procedures 
The Company has a whistleblowing policy to allow and 
encourage all employees to bring matters which cause them 
concern and in strict confidence to the attention of certain 
persons within the Company and, ultimately, to the attention 
of the Chairman. These matters include but are not limited to 
unethical business practices, fraud, misconduct, or wrongdoing.
Anti-bribery and corruption policies
All staff and Directors are bound by the Company's Anti 
Bribery and Corruption policies. The Company has a zero-
tolerance approach with its policies to protect the Company, 
its employees and those third-parties with which the business 
engages. These policies are provided to staff upon joining 
the business to ensure that everyone within the business is 
aware of the importance of all dealings within the Company 
being carried out with the highest integrity. All policies are 
regularly reviewed, and compliance training is given. Each 
employee is required to sign an agreement to confirm that 
they understand and will comply with the policies. 
Appointment of a Company Secretary to support the 
Board and ensure processes are being followed
The Company Secretary, Henry Clarke, ensures that 
the Board procedures are followed, and that applicable 
rules and regulations are complied with.  The Company 
Secretary attends the Board meetings and reports directly 
to the Executive Chairman.
Principle 10 – Communicate how the company 
is governed and is performing by maintaining a 
dialogue with shareholders and other relevant 
stakeholders 
The importance of engaging with shareholders underpins 
the essence of the business. 
As outlined at principle 2, the Company maintains an active 
dialogue with its shareholders through a planned programme 
of investor relations. It places a high priority on transparent 
and effective communications with shareholders. As an AIM 
listed company there is a need to provide fair and balanced 
information in a way that is understandable to all stakeholders. 
The Board recognises the importance of engaging with 
all stakeholders including employees, investors, partners, 
suppliers, media and communities. This is done through a 
number of channels: The primary communication tool with 
shareholders is the Company’s website, https://www.avoplc.
com. This is further supplemented by regular and appropriate 
Regulatory News Service (“RNS”) announcements as 
well as the release of the annual and interim report. The 
full year results are audited by an external firm of auditors 
with the interim statement usually subject to a review by the 
same external auditors. These reports contain full details 
of all the principal events of the relevant period together 
with an assessment of current trading and prospects. The

interim report and other investor presentations are also 
available on the website. The Company has full electronic 
communications in place, so that shareholders (unless they 
elect otherwise) will have access to communications through 
the Company’s website.
Upon conclusion of Shareholder meetings arrangements are 
made that the outcomes of votes cast by shareholders to be 
disclosed in a clear and transparent manner. If a significant 
proportion of votes (20%+) was ever cast against a resolution, 
the Company would provide, on a timely basis, an explanation 
of what actions it intends to take to understand the reasons 
behind that vote result, and, where appropriate, any different 
action it has taken, or would take, as a result of the vote.

ANNUAL REPORT 2021
The Directors are responsible for preparing the Annual 
Report and the financial statements in accordance with 
applicable law and regulations.
Company law requires the Directors to prepare financial 
statements for each financial year. Under that law the 
Directors have prepared the consolidated financial 
statements in accordance with International Financial 
Reporting Standards (IFRS) as adopted by the European 
Union (IFRSs as adopted by the EU) and have elected to 
prepare the Company financial statements in accordance 
with UK Generally Accepted Accounting Practice 
(Accounting Standards and applicable law, comprising 
FRS 101 ‘Reduced Disclosure Framework’).
In preparing the Group financial statements, International 
Accounting Standard 1 requires that Directors:
•	
properly select and apply accounting policies;
•	
make judgements and estimates that are reasonable, 
relevant, reliable and prudent;
•	
for the Group financial statements, state whether 
they have been prepared in accordance with IFRSs 
as adopted by the EU;
•	
for the parent Company financial statements, state 
whether applicable UK accounting standards have 
been followed, subject to any material departures 
disclosed and explained in the parent company 
financial statements;
•	
use the going concern basis of accounting unless 
they either intend to liquidate the Group or the parent 
Company or to cease operations, or have no realistic 
alternative but to do so.
The Directors are responsible for keeping adequate 
accounting records that are sufficient to show and explain 
the parent Company's transactions and disclose with 
reasonable accuracy at any time the financial position of 
the parent Company and enable them to ensure that its 
financial statements comply with the Companies Act 2006. 
They are responsible for such internal control as they 
determine is necessary to enable the preparation 
of financial statements that are free from material 
misstatement, whether due to fraud or error, and have 
general responsibility for taking such steps as are 
reasonably open to them to safeguard the assets of 
the Group and to prevent and detect fraud and other 
irregularities.
Under applicable law and regulations, the Directors are 
also responsible for preparing a strategic report, Directors' 
report, Directors' remuneration report and corporate 
governance statement that complies with that law and 
those regulations.
The Directors are responsible for the maintenance and 
integrity of the corporate and financial information included 
on the company's website. Legislation in the UK governing 
the preparation and dissemination of financial statements 
may differ from legislation in other jurisdictions. 
Provision of information to the auditor
Each Director in office at the date the Directors’ Report is 
approved confirms that:
•	
so far as the Director is aware, there is no relevant 
audit information of which the Company’s auditor is 
unaware; and
•	
he/she has taken all the steps that he/she ought to 
have taken as Director to make himself/herself aware 
of any relevant audit information and to establish that 
the Company’s auditor is aware of that information.
Responsibility statement of the Directors in respect of 
the annual financial report
We confirm that to the best of our knowledge:
•	
the financial statements, prepared in accordance 
with the applicable set of accounting standards, give 
a true and fair view of the assets, liabilities, financial 
position and profit or loss of the Company; and
•	
the strategic report includes a fair review of the 
development and performance of the business, 
together with a description of the principal risks and 
uncertainties that they face.
We consider the annual report and accounts, taken as a 
whole, is fair, balanced and understandable and provides 
the information necessary for shareholders to assess the 
Group's position and performance, business model and 
strategy.

ANNUAL REPORT 2021
Introduction
As Chairman of the Audit Committee, I am pleased to 
present the report of the Audit Committee for the year 
ended 31 December 2021.
This report sets out the work of the Audit Committee 
over the past year and offers insight into how the Audit 
Committee has discharged the responsibilities delegated 
to it by the Board and the key areas of focus is has 
considered in doing so.
In meeting its responsibilities, the Audit Committee 
continues to consider the provisions of the UK Corporate 
Governance Code and the FRC Guidance on Audit 
Committees. The Audit Committee’s Terms of Reference 
are available on www.avoplc.com.
Composition and meetings
The composition of the Audit Committee and attendance is 
shown on page 92. The members of the Audit Committee 
are independent Non-Executive Directors who possess 
the necessary depth of financial and commercial expertise 
to fulfil their role. Detailed information on the experience, 
skills and qualifications of all Committee members can 
be found on pages 81 and 82. The Board is satisfied that 
the Committee Chair, Hans von Celsing, has recent and 
relevant financial experience. 
Although not members of the Audit Committee, the CEO, 
the SVPs (Finance and Accounting) and the Company 
Secretary are also invited to attend meetings, unless they 
have a conflict of interest. Other senior members of the 
business are invited to attend meetings as appropriate. 
Representatives of the external auditors meet with the 
Audit Committee at least once a year without Executive 
Directors or management being present.
Primary responsibility and matters considered
This is further outlined on page 92.
Fair, balanced and understandable
The Audit Committee undertook an assessment as to 
whether, in its view, the Annual Report and Accounts 
were fair, balanced and understandable, and provided 
the necessary information for shareholders to assess the 
position, performance, business model and strategy of 
the Company. In forming its opinion, the Audit Committee 
considered the results of management’s assessment of 
going concern, reviewed the Annual Report and Accounts 
as a whole, and assessed the results of processes 
undertaken by management to provide assurance that the 
Group’s financial statements were fairly presented. These 
processes included, but were not limited to:
•	
Review by senior management of the Annual 
Report to ensure that the information presented was 
accurate and that the narrative was consistent with 
the fact pattern, including appropriate disclosure 
of material or significant items necessary to aid a 
reader’s understanding and appropriate balance of 
reported and adjusted performance measures;
•	
Board meetings where the financial projections were 
reviewed to ensure that the business performance 
was appropriately assessed and understood.
•	
Discussion with senior management and a review 
of any significant judgements or estimates made by 
management in preparing the Annual Report.
The views of the external auditors on this matter were also 
considered by the Audit Committee. Having completed its 
assessment, the Audit Committee reported to the Board 
that it was able to make the corresponding confirmation in 
its Directors’ responsibility statement.
In conclusion, the Audit Committee reported to the Board 
that it considers the Annual Report for the year ended 31 
December 2021 to be fair, balanced and understandable.
Risks
The Audit Committee oversees the effectiveness of the 
Group’s risk management and reviews and monitors the 
key risks in order to eliminate or mitigate against those 
risks. The Audit Committee has assured itself that a risk 
management framework is in place and effective; it is 
satisfied that risks are within the risk appetite of the Group 
and, where mitigating actions are undertaken, they are 
proportionate. 
In relation to financial reporting, the Audit Committee has 
discussed areas of risk with the auditors and agreed for 
AUDIT COMMITTEE 
REPORT
Hans von Celsing 
Chairman of the Audit Committee 

the following areas of heightened risk to be reviewed and 
assessed in the audit of the Group’s performance in the 
financial year to 31 December 2021: 
•	
Carrying value of intangibles; 
•	
Carrying value of inventory; 
•	
Accounting for convertible loan agreements; and 
•	
Going concern. 
For each of the above areas the Audit Committee 
considered the key facts and judgements outlined 
by management. Key findings are provided in the 
Independent Auditor's Report on pages 105 to 108. The 
Audit Committee was satisfied that there are relevant 
accounting policies in place in relation to these key areas 
and management have correctly applied these policies. 
External auditors
Role of the external auditors
The Audit Committee monitors the relationship with its 
external auditors, RPG Crouch Chapman LLP, to ensure 
that auditor independence and objectivity are maintained. 
Audit process
The external auditors prepare an audit plan for review of 
the full-year financial statements. The audit plan sets out 
the scope of the audit, specific areas of risk to target and 
the audit timetable. This plan is reviewed and agreed in 
advance by the Audit Committee. Following completion 
of audit fieldwork the external auditors present their 
findings to the Audit Committee for discussion, including 
accounting judgements undertaken in respect of various 
matters such as research and development capitalisation.
Non-audit fees
Any non-audit services require approval by the Audit 
Committee. Non-audit fees comprised predominantly fees 
for tax compliance and ad hoc tax work. Non-audit fees 
amounted to £8,750 (2020: £8,500) compared to £56,350 
(2020: £54,750) of audit fees.
Tax compliance services provided by RPG Crouch 
Chapman LLP do not involve the making of any decisions 
and are carried out by a separate team not involved with 
the audit work. The company has informed management 
in place that make all tax related decisions. The tax 
disclosures are also drafted before the completion of the 
tax compliance work and RPG Crouch Chapman LLP play 
no part in the drafting of these disclosures.
Auditor effectiveness and appointment
RPG Crouch Chapman LLP has served as external 
auditors of the Company since 2011. Periodic rotation of 
key audit partners is also required. This is the first year 
that Mark Wilson has acted as the audit partner for the 
group. Mark brings his experience of working with listed 
groups and reporting under IFRS.
In line with its Terms of Reference, the Audit Committee 
undertakes an annual assessment of the effectiveness, 
value and independence of the external auditors. This 
assessment incorporates the views of management 
in addition to the Non-Executive Directors to facilitate 
continued improvement in the external audit process.
The assessment considered:
•	
Audit risk identification whereby this is a key factor in 
the delivery of a thorough, robust and efficient global 
audit in accordance with pre-set timescales. These 
risks remained broadly consistent with the prior 
financial year;
•	
Provision of accurate, robust and perceptive advice 
on key accounting and audit judgements, technical 
issues and best practice;
•	
The level of professionalism and technical expertise 
consistently demonstrated and maintenance of 
continuity within the core audit team; and
•	
Strict adherence to independence policies and other 
regulatory requirements.
RPG Crouch Chapman’s objectivity, independence and 
performance are considered to remain strong and the 
Audit Committee has recommended to the Board that 
RPG Crouch Chapman’s be re-appointed as external 
auditors for the next financial year, subject to approval at 
the AGM.
Internal audit
At present the Company does not have a formal internal 
audit function; the Audit Committee presently considers 
this to be appropriate given the close involvement of the 
Executive Directors and senior management on a day-to-
day operational basis.  The Audit Committee will keep this 
matter under review as the Group’s activities expand.
Conclusions
The Audit Committee’s oversight of financial reporting, 
external audit, and the further development of the control 
and risk environments have been areas of significant 
focus. These are likely to remain so for the next financial 
year as the Company grows and develops in line with its 
strategy.
The Audit Committee remains focused on ensuring that 
finance and risk capability is enhanced appropriately 
to manage in an increasingly complex business and an 
increasingly regulated environment.
I am confident that the Audit Committee has the necessary 
skills and experience to continue to meet the challenges 
ahead.

ANNUAL REPORT 2021
Introduction
As Chairman of the Remuneration Committee, I am 
pleased to present the report of the Remuneration 
Committee for the year ended 31 December 2021.
This report does not constitute a Directors’ remuneration 
report in accordance with the Companies Act 2006. As 
a company whose shares are admitted to trading on 
AIM, the Company is not required by the Companies Act 
to prepare such a report. However, the Remuneration 
Committee is committed to complying with the principles 
of good corporate governance in relation to the design 
of the Directors’ remuneration policy. As such, our policy 
takes account of the UK Corporate Governance Code 
and the QCA Corporate Governance Code (against 
which the Company formally reports compliance). The 
Remuneration Committee also considers other best 
practice guidance (for example, the QCA Remuneration 
Committee Guide and the Investment Association’s 
Principles of Remuneration), as far as is appropriate to 
the Company’s management structure, size and listing. 
The Remuneration Committee’s Terms of Reference are 
available on www.avoplc.com.
Composition and meetings
During the past year, the Remuneration Committee, 
chaired by Enrico Vanni, was exclusively composed of 
independent Non-Executive Directors. The Executive 
Chairman and the Chief Executive Officer are invited to 
attend meetings where appropriate. The Remuneration 
Committee met three times in 2021. The composition of 
the Remuneration Committee and attendance can be 
found on page 92.
Primary responsibility and matters considered
This is further outlined on page 92.
Remuneration policy
The remuneration policy of the Company is to:
•	
provide a suitable remuneration package to attract, 
motivate and retain Executive Directors and the wider 
Executive team who will run the Group successfully; 
and
•	
ensure that all long-term incentive schemes for 
the Directors are consistent with the shareholders’ 
interests.
The Remuneration Committee reviews overall levels of 
pay and the operation of the incentive arrangements for 
Executive Directors to ensure they remain appropriate in 
light of the current business strategy and the interests of 
shareholders. More specifically, these reviews are framed 
around the following key principles: 
•	
total rewards will be set at levels that are sufficiently 
competitive to enable the recruitment and retention of 
high-calibre executives; 
•	
total incentive-based rewards will be earned through 
the 
achievement 
of 
demanding 
performance 
conditions consistent with shareholder interests; 
•	
incentive plans, performance measures and targets 
will be structured to operate soundly throughout the 
business cycle; 
•	
the design of long-term incentives will be prudent 
and will not expose shareholders to unreasonable 
financial risk; 
•	
in considering the market positioning of reward 
elements, account will be taken of the performance 
of the Group and of each individual senior team 
member; and 
•	
reward practice will conform to best practice 
standards as far as reasonably practicable.
No Director or senior manager is involved in any decisions 
about their own remuneration. The Remuneration 
Committee 
is, 
however, 
responsible 
for 
making 
recommendations to the Directors on matters relating to 
the Company’s remuneration structure, including pension 
rights, the policy on compensation for Executive Directors 
and their terms of employment. In order to achieve the 
overall aim of attracting and retaining high-quality people, 
the Remuneration Committee has continued to provide a 
suitable balance of short-term and long-term incentives.
The policy on each element of remuneration and how it 
operates, is also detailed on the following page. The main 
elements of the remuneration packages are as follows.
Basic annual salary and pension 
Base salary is based on a number of factors, including 
market rates, benchmarking to peers, as well as the 
individual Director’s experience, responsibilities and 
performance. Individual salaries are subject to annual 
review. 
All Executive Directors, along with other employees, are 
able to take part in the Company’s pension scheme, 
where they receive a pension contribution from the Group 
of up to 10% of salary together with employer’s National

Insurance saved on employee pension contributions. This 
complies with legal requirements, with both the employee 
and employer making contributions under automatic 
enrolment provisions.
Other benefits 
All employees benefit from life assurance and medical 
health insurance. Other benefits may also be provided to 
employees once they have met eligibility criteria. 
Discretionary bonus 
The purpose of the annual bonus is to incentivise the 
Executive Directors, members of the Executive team 
and senior management to deliver strategic and financial 
success, as well as long-term growth to the benefit of 
the Company and its shareholders. Bonus awards take 
into account Company and individual performance. 
They are either related to the achievement of personal, 
departmental and/or Group targets/milestones. 
In addition, the Remuneration Committee has the 
discretion to settle an element of any bonus in shares or 
share options in lieu of cash considerations. The extent 
of such discretions and the maximum opportunity for 
performance metrics is set out on page 99. To ensure 
the efficient administration of the variable incentive plans 
outlined, the Remuneration Committee applies certain 
operational discretions which include the following:
•	
selecting the participants in the plans on an annual 
basis;
•	
determining the timing of grants of awards and/or 
payments;
•	
determining the quantum of awards and/or payments;
•	
determining the extent of vesting based on the 
assessment of performance as well as taking into 
account the experience of shareholders and other 
stakeholders over the vesting period;
•	
determining ‘good leaver’ status for incentive plan 
purposes and applying the appropriate treatment; 
and
•	
undertaking the annual review of weighting of 
performance measures and setting targets for the 
annual bonus plan and other incentive schemes, 
where applicable, from year to year. 
Long-term incentive plan and save as you earn 
scheme
In 2020 the Remuneration Committee established a Long-
Term Incentive Plan (“LTIP”).  In 2018 the Remuneration 
Committee set-up a Save As You Earn (“SAYE”) scheme. 
The Executive team and certain key individuals in the 
Company were invited to join the LTIP and SAYE scheme. 
The purpose of the LTIP and the SAYE scheme are to 
provide a long-term performance and retention incentive, 
linking long-term share rewards to the creation of long-
term sustainable shareholder value by delivering on the 
Company’s agreed strategic objectives.
Details can be found on page 99. 
Differences in the remuneration policy of the 
executive directors and the general employees
There are no material differences in the structure of 
remuneration arrangements for the Executive Directors 
and senior management, aside from quantum and 
participation levels in incentive schemes, which reflect the 
fact that a greater emphasis is placed on performance-
related pay for Executive Directors and the most senior 
individuals in the management team. 
Non-executive Directors 
Fees for Non-Executive Directors are determined by 
the Board on the recommendation of the Remuneration 
Committee, based on market comparisons with positions 
of similar responsibility and scope in companies of a 
similar size and in comparable industries. Non-Executive 
Directors are not eligible for pension scheme membership 
or to participate in the Company’s LTIP; and do not 
participate in any of the Company’s bonus schemes or 
receive any other benefits. 
As with the Executive Directors, Non-Executive Directors’ 
fees are designed to attract and retain individuals 
who have the expertise, responsibility and the time 
commitment to be able to contribute to an effective Board 
and deliver long-term sustainable shareholder value. 
The Company reimburses Non-Executive Directors for 
reasonable expenses incurred such as travel and hotel 
accommodation.
Most Non-Executive Directors have historically elected to 
receive their fees in shares of the Company. Please refer 
to Directors' shareholding on page 102 and options on 
page 124.
In addition to an annual fixed fee of £30,000, Non-Executive 
Directors are paid additional fees for memberships of 
Board Committees. Fees for Non-Executive Directors are 
set by the Board.
•	
Committee Chairmanship fee: £15,000
•	
Other Committee Membership fee: £10,000
Conclusion 
The Board firmly believes that the remuneration policy 
of the Company effectively rewards and incentivises the 
executive and senior management team in pursuit of the 
Company’s strategic aims and that these incentives align 
with long-term stakeholder value creation.

Directors – power, protection and interests
Description
The Directors and brief biographies are detailed on pages 

December 2020 are set out below:
In the financial year,  the Company expensed through the 
income statement £140,000 (2020: £40,000) in relation 
to research and development costs; these largely relate 
to ADAM physics consultancy costs not capitalised as an 
intangible asset. Additionally, £12.5 million (2020: £5.8 
million) of development costs were capitalised.
At the date of this report, there is no contract or arrangement 
with the Company or any of its subsidiaries that is 
significant in relation to the business of the Company in 
which a Director of the Company is materially interested.
Further information – including details on non-beneficial 
interests and Directors’ share options – are contained in 
the Directors’ remuneration report set out on pages 97 to 
99 and in Note 8 on page 124.
The Directors have a statutory duty under the Companies 
Act 2006 to avoid situations in which they have, or can have, 
a direct or indirect interest that conflicts, or may conflict, with 
the interests of the Company. Details on conflict of interests 
can be found on page 87 (Principle 5 of the QCA Code).
Business activity and review
Business review
The Company is still pre-revenue and continues to invest in 
the development and assembly of the first LIGHT machine 
through expenditure on intangible assets and inventory. It 
recorded a comprehensive loss of £30.2 million in the year 
ended 31st December 2021 (2020: £23.4 million), with 
shareholder funds as at 31st December 2021 of £61.4 million 
(2020: £44.1 million). Cash and cash equivalents at the year-
end were £4.3million (2020: £2.3 million), although these year-
end figures do not take into account post period financing 
agreements. The Company has funded its operations through 
borrowings and equity raises.Further details of the results for 
the year are set out in the Consolidated Income Statement and 
in the related notes forming part of the Consolidated Financial 
Statements. The Chairman’s letter and the Chief Executive 
Officer’s Review – which are included in the Strategic Report – 
report on the performance of the Group’s business during the 
year and on future developments.
Dividends
The Directors do not recommend the payment of a dividend 
(2020: no dividend) so that cash is retained in the Company for 
assembling the first LIGHT machine and capital expenditures 
that are required for the rapid growth of the business.
Donations 
During the year, the Company made no charitable 
donations (2020: nil).
Likely future developments
The outlook is available on pages 6, 37, 38 and 49 to 52. 
Going concern
The Group has made a loss before tax of £29.5m (2021: 
£23.4m) and is presently pre-revenue and, as such, 
has relied upon equity and debt funding to progress 
its development plans. Post year end, the Group has 
successfully raised £11.5m in equity and £1.5m in short 
term loans as detailed further in Note 29.
 
The Directors regularly review cash flow forecasts to 
determine whether the Group has sufficient cash reserves 
to meet its future working capital requirements and 
development plans. The Group’s plans indicate that they 
need to raise further finance and the Directors are confident 
based on past history of successful fundraising and 
discussions with investors that the Group will be successful 
in raising these funds. Additionally, they consider they can 
defer settlement of creditors, reduce short term expenditure 
and obtain short-term finance should there be any delay 
in completing any such fundraising to allow continuance of 
their plans. They therefore consider it appropriate to prepare 
the Group’s financial statements on a going concern basis.
 
However, as at the date of approval of these financial 
statements, there are no legally binding agreements in 
place in relation to any fundraising or extension of terms 
with creditors and as the success of any finance raising is 
outside the control of the company there can be no certainty 
that additional funds will be forthcoming, which indicates the 
existence of a material uncertainty which may cast doubt 
about the Group’s ability to continue as a going concern and 
therefore it may be unable to realise its assets and discharge 
its liabilities in the normal course of business. The financial 
statements do not include the adjustments that would result if 
the Group was unable to continue as a going concern.
Share structure
Share capital
As at 31st December 2021, the Company had an allotted 
and fully paid up share capital of 451,612,211 ordinary 
shares of 25 pence each with an aggregate nominal value 
of £113 million. Further details of the authorised and issued 
share capital, together with details of the movements in 
the Company’s issued share capital during the year are

ANNUAL REPORT 2021
set out in Note 20 to the consolidated financial statements.
The Company has one class of ordinary shares which are 
listed on the Alternative Investment Market (“AIM”) and 
trade under the ticker symbol: LON: AVO. 
Rights of shareholders
The rights attached to the ordinary shares of the Company 
are defined in the Company’s Articles. Each share carries 
the right to one vote at general meetings of the Company 
but has no right to fixed income.
Shareholders are entitled to attend and vote at any general 
meeting of the Company. It is the Company’s practice to 
hold a poll on every resolution at general meetings. Every 
member present in person or by proxy has, upon a poll, one 
vote for every share held. In the case of joint holders of a 
share the vote of the senior who tenders a vote, whether in 
person or by proxy, shall be accepted to the exclusion of the 
votes of the other joint holders and, for this purpose, seniority 
shall be determined by the order in which the names stand in 
the Register of Members in respect of the joint holding. 
No person has any special rights of control over the 
Company’s share capital.
Transfer of shares
There are no specific restrictions on the size of a holding, 
nor on the transfer of shares which are both governed 
by the general provisions of the Company’s Articles and 
prevailing legislation.
Shareholder agreement
The Directors are not aware of any agreements between 
holders of the Company’s shares that may result in 
restrictions on the transfer of securities or on voting rights 
at any meeting of the Company.
Major shareholdings
As at 30th March 2022,  the Company had been notified under 
the FCA’s Disclosure, Guidance and Transparency Rule of the 
following interests in its total voting rights of 3% or more:
On 27th May 2022, the Company was informed that Odey 
Asset Management LLP had a total beneficial interest in 
20,281,159 ordinary shares in the Company, representing 
4.3% of the Company's issued share capital at that time.
Employees 
Diversity 
The Company is committed to encouraging diversity, 
promoting a diverse culture where everyone is treated 
with respect and valued for their individual contribution 
and creating a work environment free of bullying, 
harassment, victimisation, and unlawful discrimination. 
The Company has policies in place to ensure that 
selection for employment, promotion, development, 
or any other benefit is on the basis of merit and ability 
and does not impact negatively upon diversity. It is a key 
objective to ensure that all employees are helped and 
encouraged to fulfil their potential. 
Equal opportunities 
It is the Company’s policy to ensure equal opportunity 
in 
recruitment, 
selection, 
promotion, 
employee 
development, training and reward policies and we have 
an equal opportunity and diversity policy in place. It is a 
key objective to ensure that successful candidates for 
appointment and promotion are selected taking account 
of individual ability, skills, and competencies without 
regard to age, gender, race, religion, disability or sexual 
orientation. Every effort is also made to retain and support 
employees who have a disability during their employment, 
including flexible working to assist their re-entry into the 
workplace and making alternative suitable provisions.
Involvement of employees 
Employees are key to the Company’s success, and the 
Company relies on a committed workforce to help achieve 
the business objectives. Employees are encouraged to 
operate in an open environment, embracing teamwork 
and aligning personal development with the strategy of 
the business and their behaviours with Company values. 
Directors are keen to engage Company’s employees by 
providing an environment where they can contribute their 
own ideas and challenge those of others. Directors are 
committed to involving employees and consider that good 
communication helps to achieve this. Further information 
– including the way in which Directors discharge the duty 
of taking into consideration the interests of employees and 
other stakeholders – can be found on page 86 (Principle 
3 of the QCA Code) and on pages 71 and 72.
Employee share plans 
To aid in retention, a benefits package encompassing 
death in service and medical insurance, together with a 
contributory pension scheme, is offered to all employees, 
in addition to salary. Discretionary bonus scheme can also 
be available subject to the satisfaction of any applicable 
performance conditions at the time. The Company 
operates several employee share plans, details of which 
are set out on page 99.

Cautionary 
statement 
regarding 
forward-
looking information
Forward-looking statements are subject to assumptions, 
inherent risks and uncertainties, many of which relate to 
factors that are beyond the Company’s control or precise 
estimate. Directors caution investors that a number 
of important factors, including those referred to in the 
Company’s annual report, could cause actual results to 
differ materially from those expressed or implied in any 
forward-looking statement. Such factors include, but are 
not limited to, those discussed in the Risk section on 
pages 73 and 76. Any forward-looking statements made 
by or on behalf of the Company speak only as of the date 
they are made and are based upon the knowledge and 
information available to the Directors on the date of this 
report.
Events after the reporting period
Since the year end, the Group has raised additional 
equity through the issue of shares:
On 23 March 2022, the Company entered into a new 
short term loan agreement of £1.5 million with Nerano 
Pharma Ltd, a company owned and controlled by Seamus 
Mulligan, a significant shareholder in the Company, with 
an interest rate of 1.25 per cent per month (the "Loan"). 
The Loan is repayable by the Company on 24 June 2022. 
As part of the agreement, the Company issued 6,382,978 
warrants to Nerano Pharma Ltd with an exercise price 
of 28.20 pence per share, exercisable up until 24 March 
2025.
 
As at the date of publication of the annual accounts, 
the Loan remains outstanding. Nerano Pharma has 
agreed to not seek repayment at the current time and 
are in discussions with the Company surrounding the 
potential to convert the Loan into New Ordinary Shares. 
At the current time no agreement has been entered into 
in relation to varying the terms of the Loan nor have the 
terms of any variation been, as yet, agreed. In the event 
that the terms cannot be agreed between Nerano Pharma 
and the Company, the Company would seek to repay the 
amounts owed pursuant to the Loan.

ANNUAL REPORT 2021
Opinion
We have audited the financial statements of Advanced 
Oncotherapy plc (the ‘Company’) and its subsidiaries (the 
‘Group’) for the year ended 31 December 2021 which 
comprise the Consolidated statement of comprehensive 
income, the Consolidated statement of financial position, 
the Consolidated statement of changes in equity, the 
Consolidated statement of cash flows, the Company 
statement of financial position, the Company statement of 
changes in equity, and notes to the financial statements, 
including a summary of significant accounting policies.
The financial reporting framework that has been applied 
in the preparation of the Group financial statements is 
applicable law and International Financial Reporting 
Standards as adopted in the United Kingdom (IFRS). 
The Company financial statements have been prepared 
in accordance with applicable law and United Kingdom 
Accounting Standards, including FRS 101 Reduced 
Disclosure Framework (UK GAAP).
In our opinion:
•	
the financial statements give a true and fair view of 
the state of the Group’s and of the Company’s affairs 
as at 31 December 2021 and of the Group’s loss for 
the year then ended;
•	
the Group financial statements have been properly 
prepared in accordance with IFRS;
•	
the Company financial statements have been 
properly prepared in accordance with UK GAAP; and
•	
the financial statements have been prepared in 
accordance with the requirements of the Companies 
Act 2006.
Basis for audit opinion
We conducted our audit in accordance with International 
Standards on Auditing (UK) (ISAs (UK)) and applicable 
law. 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 group in accordance with the 
ethical requirements that are relevant to our audit of the 
financial statements in the UK, including the FRC’s Ethical 
Standard as applied to listed entities, 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 1b in the accounting policies, 
concerning the Group’s ability to continue as a going 
concern. The matters explained in Note 1b indicate 
that the Group needs to raise further finance to fund its 
working capital needs and development plans. As at the 
date of approval of these financial statements there are 
no legally binding agreements relating to securing the 
required funds. These events or conditions along with the 
matters set forth in Note 1b indicate the existence of a 
material uncertainty which may cast significant doubt over 
the Group’s ability to continue as a going concern. Our 
opinion is not modified in respect of this matter.
We have highlighted going concern as a key audit matter. 
In auditing the financial statements, we have concluded 
that the Directors’ use of the going concern basis of 
accounting in the preparation of the financial statements is 
appropriate. Our evaluation of the Directors’ assessment 
of the Group and the Parent Company’s ability to continue 
to adopt the going concern basis of accounting included:
•	
Analysing Management’s and the Directors’ cashflow 
forecast which forms the basis of their assessment 
that the going concern basis of preparation remains 
appropriate for the preparation of the Group and 
Company financial statements for a period of at least 
twelve months from the date of approval of these 
financial statements;
	INDEPENDENT AUDITOR’S 
REPORT

•	
Testing the integrity of the cashflow model;
•	
Assessing costs included within the cashflow forecast 
and where available agreeing these costs to other 
evidence obtained during the course of our audit 
work is in line with our expectations;
•	
Obtaining details of post year ends fundraisings 
and agreeing supporting documentation and cash 
received;
•	
We reviewed loan agreements and ensured the 
repayments were appropriately included in the 
forecasts;
•	
Discussing with Management and the Board the 
Group’s strategy to continue to ensure funds are 
available to the Group to fund its plans;
•	
Sensitising the cash flows for changes in key 
assumptions and considering the impact on 
headroom; and
•	
Reviewing and considering the adequacy of the 
disclosure within the financial statements relating to 
the Directors’ assessment of the going concern basis 
of preparation.
Our approach to the audit
In planning our audit, we determined materiality and 
assessed the risks of material misstatement in the financial 
statements. In particular, we looked at where the Directors 
made subjective judgements, for example in respect of 
significant accounting estimates. As in all of our audits, 
we also addressed the risk of management override of 
internal controls, including evaluating whether there was 
evidence of bias by the Directors that represented a risk of 
material misstatement due to fraud.
We tailored the scope of our audit to ensure that we 
performed sufficient work to be able to issue an opinion 
on the financial statements as a whole, taking into 
account the structure of the Group and the Company, the 
accounting processes and controls, and the industry in 
which they operate.
We performed full-scope audits of the material 
components of the Group, being Advanced Oncotherapy 
Plc and ADAM S.A.. The remaining components of the 
Group were considered nonsignificant and we performed 
limited review procedures as deemed necessary.
Key audit matters
Key audit matters are those matters that, in our 
professional judgement, were of most significance in our 
audit of the financial statements of the current period and 
include the most significant assessed risks of material 
misstatement we identified (whether or not due to fraud), 
including those which had the greatest effect on: the 
overall audit strategy; the allocation of resources in the 
audit; and directing the efforts of the engagement team. 
The matter identified was 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. The use of the Going Concern 
basis of accounting was assessed as a key audit matter 
and has already been covered in the previous section of 
this report. The other key audit matters identified are listed 
below.

Key audit matter
Our audit work included:
Intangible asset valuation
The Group’s Intangible assets consist of direct costs relating to 
the internal development of the proton therapy technology and 
machines. Please refer to Note 10.
As an intangible asset not yet ready for use, Management and 
the Board are required to perform an annual impairment review. 
Given the materiality of the assets in the context of the Group’s 
consolidated statement of financial position and the judgement 
involved in making this assessment we consider this to be a key 
audit matter.
Our audit work included:
•	
Reviewing the impairment model provided and checking 
that the value in use model is appropriate;
•	
Testing the integrity of the cashflow model;
•	
Discussing with Management the assumptions used and 
obtaining details to support the key assumptions; and
•	
Sensitising the cash flow for assumptions and considering 
if the disclosures in the financial statements reflect 
appropriately the requirement to disclosure key judgements 
and estimates.
Carrying value of inventories
Inventory comprise the costs incurred to date to assemble 
machines being constructed for sale. There is judgement 
involved in the assessment of whether the carrying value is the 
lower of cost or net realisable value. We therefore consider this 
to be a key audit matter.
Our audit work included:
•	
Confirming costs to date are accurate by reference to 
invoices;
•	
Confirming costs to complete to budgets and supporting 
documents;
•	
Considering whether the budget is reasonable based on 
costs to date against original budget; and
•	
Considering sales price of similar equipment or indicated 
sales price in correspondence with potential customers.

107
ANNUAL REPORT 2021
Our application of materiality
We apply the concept of materiality both in planning 
and performing our audit, and in evaluating the effect of 
misstatements. We consider materiality to be the magnitude 
by which misstatements, including omissions, could 
influence the economic decisions of reasonable users that 
are taken on the basis of the financial statements.
In order to reduce to an appropriately low level the 
probability that any misstatements exceed materiality, 
we use a lower materiality level, performance materiality, 
to determine the extent of testing needed. Importantly, 
misstatements below these levels will not necessarily 
be evaluated as immaterial as we also take account of 
the nature of identified misstatements, and the particular 
circumstances of their occurrence, when evaluating their 
effect on the financial statements as a whole.
We have based materiality on 1.25% of reported gross 
assets for the significant components, which is consistent 
with the prior year. This benchmark is considered the 
most appropriate because assets are the key item for an 
entity in the development phase. Overall materiality for the 
Group was therefore set at £1.7m (2020: £1.5m). For each 
component, the materiality set was lower than the overall 
group materiality. For the Company, materiality was set at 
£1.3m (2020: £1.2m).
We agreed with the Audit Committee that we would report 
on all differences in excess of 5% of materiality relating to 
the Group financial statements. We also report to the Audit 
Committee on financial statement disclosure matters 
identified when assessing the overall consistency and 
presentation of the consolidated financial statements.
Other information
The Directors are responsible for the other information. 
The other information comprises the information included 
in the annual report, other than the financial statements and 
our auditor’s report thereon. Our opinion on the financial 
statements does not cover the other information and, except 
to the extent otherwise explicitly stated in our report, 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 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. If we identify such material inconsistencies 
or apparent material misstatements, we are required to 
determine whether there is a material misstatement in the 
financial statements or a material misstatement of the other 
information. If, based on the work we have performed, 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.
Opinions on other matters prescribed by the 
Companies Act 2006
In our opinion, based on the work undertaken in the 
course of the audit:
•	
the information given in the strategic report and the 
Directors’ report for the financial year for which the 
financial statements are prepared is consistent with 
the financial statements; and
•	
the strategic report and the Directors’ report have 
been prepared in accordance with applicable legal 
requirements.
Matters on which we are required to report by 
exception
In the light of the knowledge and understanding of the 
Group and the Company and its environment obtained 
in the course of the audit, we have not identified material 
misstatements in the strategic report or the Directors’ report.
We have nothing to report in respect of the following 
matters in relation to which the Companies Act 2006 
requires us to report to you if, in our opinion:
•	
adequate accounting records have not been kept by 
the Group or the Company, or returns adequate for 
our audit have not been received from branches not 
visited by us; or
•	
the Group or the Company financial statements are 
not in agreement with the accounting records and 
returns; or
•	
certain disclosures of Directors’ remuneration 
specified by law are not made; or
•	
we have not received all the information and 
explanations we require for our audit.
Responsibilities of Directors
As explained more fully in the Directors’ responsibilities 
statement set out on page 93 the Directors are responsible 
for the preparation of the financial statements and for being 
satisfied that they give a true and fair view, and for such 
internal control as the Directors determine 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, the Directors are 
responsible for assessing the group’s and the parent 
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 
the Directors either intend to liquidate the group or the 
parent company or to cease operations, or have no 
realistic alternative but to do so.
Auditor’s responsibilities for the audit 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 our opinion in an auditor’s report. Reasonable 
assurance is a high level of assurance, but does not 
	INDEPENDENT AUDITOR’S 
REPORT

guarantee that an audit conducted in accordance with ISAs 
(UK) will always detect a material misstatement when it 
exists. Misstatements can arise from fraud or error and are 
considered material if, individually or in aggregate, they could 
reasonably be expected to influence the economic decisions 
of users taken on the basis of the financial statements.
Irregularities, including fraud, are instances of non-compliance 
with laws and regulations. We design procedures in line 
with our responsibilities, outlined above, to detect material 
misstatements in respect of irregularities, including fraud. 
The extent to which our procedures are capable of detecting 
irregularities, including fraud, is detailed below:
We gained an understanding of the legal and regulatory 
framework applicable to the Group and the industry 
in which it operates and considered the risk of acts by 
the group which were contrary to applicable laws and 
regulations, including fraud. These included but were 
not limited to compliance with Companies Act 2006 and 
applicable accounting standards. 
We designed audit procedures to respond to the risk, 
recognising that the risk of not detecting a material 
misstatement due to fraud is higher than the risk of not 
detecting one resulting from error, as fraud may involve 
deliberate concealment.
We focused on laws and regulations that could give rise to 
a material misstatement in the financial statements. Our 
tests included, but were not limited to:
•	
agreement of the financial statement disclosures to 
underlying supporting documentation;
•	
enquiries of management;
•	
review of minutes of board meetings throughout the 
period; and
•	
obtaining an understanding of the control environment 
in monitoring compliance with laws and regulations.
Because of the inherent limitations of an audit, there 
is a risk that we will not detect all irregularities, including 
those leading to a material misstatement in the financial 
statements or non-compliance with regulation. This risk 
increases the more that compliance with a law or regulation 
is removed from the events and transactions reflected in 
the financial statements, as we will be less likely to become 
aware of instances of non-compliance. The risk is also 
greater regarding irregularities occurring due to fraud 
rather than error, as fraud involves intentional concealment, 
forgery, collusion, omission or misrepresentation.
A further description of our responsibilities for the audit of the 
financial statements is located on the Financial Reporting 
Council's website at: www.frc.org.uk/auditorsresponsibilities. 
This description forms part of our Auditor's Report.
Use of our report
This report is made solely to the Company’s members, 
as a body, in accordance with Chapter 3 of Part 16 of 
the Companies Act 2006. Our audit work has been 
undertaken so that we might state to the Company’s 
members those matters we are required to state to them in 
an auditor’s report and for no other purpose. To the fullest 
extent permitted by law, we do not accept or assume 
responsibility to anyone other than the company and the 
company’s members, as a body, for our audit work, for this 
report, or for the opinions we have formed.

NOTES TO 
THE ACCOUNTS – GROUP
Continued - Financials in £
 1. Principal accounting policies – Group
a. Accounting convention, basis of preparation and going concern
These financial statements have been prepared under accordance with international accounting standards in conformity with the 
requirements of the Companies Act 2006. The financial statements have been prepared on the historical cost basis modified to 
include certain assets and liabilities at fair value.
The Directors have taken advantage of the exemption offered by Section 408 of the Companies Act 2006 not to prepare a separate 
statement of comprehensive income for the Parent Company.
Advanced Oncotherapy PLC (“the Company”) is a public limited company incorporated and domiciled in the UK. The nature of the 
operations and principal activities of the Company and its subsidiary undertakings (the “Group”) are set out in the Strategic Report 
on pages 1 to 76 and the Directors’ report on pages 101 to 104. These consolidated financial statements are presented in pounds 
sterling because that is the predominant currency of the economic environment in which the Group operates.
Use of estimates and judgements
The preparation of financial statements in conformity with IFRS requires management to make judgements, estimates and 
assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The 
estimates and associated assumptions are based on historical experience and opinions or statements received from competent 
professional advisors. The assumptions used are considered to be reasonable under the circumstances and the results of which 
form the basis of making judgements about the carrying values of assets and liabilities that are readily apparent from other sources. 
Actual results may differ from these estimates. 
Estimates and assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in 
which the estimates are revised if the revisions affects only that period. 
Critical estimates and judgements that have the most significant effect on the amounts recognised in the financial statements and/
or have a significant risk attached to:
1.	
The values ascribed to Intangible assets. The Directors carried out an impairment review of the Intangible assets and found that 
no impairment is necessary. At 31 December 2021, the Group held intangible assets currently still being developed, for which 
the most sensitive assumption is the probability of technical success and, given their nature, impairment adjustments triggered 
by future events that have yet to occur which may be material. In addition, there is a significant risk that impairments recognised 
in any one period may be subject to material adjustments in future periods. See Note 10 and Note w below.
2.	
Inventory. The Directors have made significant accounting estimates in respect of the carrying value of inventory at the year-end 
both in respect of estimated selling prices and costs to complete the inventory. These estimates have been based on quoted 
amounts from suppliers and on discussions with or signed contracts with potential customers. An impairment provision of £nil 
(2020: £1.9m) has been provided. Some sales values are contractually agreed thus a 20% reduction in those not agreed would 
lead to an impairment of £1.1m. An increase in expected costs of 20% would lead to an impairment of £4.3m. 
3.	
Incremental interest rates on Leases. On adoption of IFRS 16, the Group recognised lease liabilities in relation to leases which 
had previously been classified as ‘operating leases’ under the principles of IAS 17 Leases. These liabilities were measured at 
the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as of 1 January 
2020. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on 1 January 2020 was 3.0%. 
The determination of applicable incremental borrowing rates at the commencement of new lease contracts also requires 
judgement. The Group determines its incremental borrowing rates by obtaining interest rates from various external financing 
sources and makes certain adjustments to reflect the terms of the lease. The Group considers the relevant market interest rate, 
based on the weighted average of the timing of the lease payments under the lease obligation. 
4.	
Going concern – refer to Note 1b for judgments in respect of the going concern basis of preparation.
5.	
Valuation of share based payments – the estimation related to share based payments includes the selection of an appropriate 
valuation option pricing model, consideration as to the inputs into the valuation model chosen and the estimation of the number 
of the awards that will ultimately vest. Inputs subject to estimation relate to the future volatility of the share price based on 
historically observed volatility from trading in the Company’s shares, over a historical period between the date of grant and the 
date of exercise. Management has used a Monte Carlo model to calculate the fair value of the awards which include market 
based conditions. Further disclosure of inputs relevant to the calculations is set out in Note 21.
6.	
Accounting for loan agreements and valuation of embedded derivative – management have applied judgement in accounting for 
the loan received from Nerano. In determining the appropriate accounting, they have considered the terms of the arrangement 
and identified that the loan contains an embedded derivative that needs to be recognised separately from the host contract. 
Additionally, they have applied judgement in determining which of the cash flows arising from the arrangement can be estimated 
reliably in determining what should be included in the amortised cost calculation.  	
	
	
	
	
	
	
	
	
	
	
	
	
	
	
	
	
	
	
The fair value of the embedded derivative has been determined through a range of inputs and modelling the results of the 
change in these inputs. Inputs are determined based on past performance, comparable instruments and management’s 
determination of the suspected future time horizons for the conversion of the instruments. These forecasted values are by their 
nature estimates and therefore there is uncertainty with relation to the valuation of these instruments. Further details in relation 
to the valuation of these instruments can be found in Note 18.

GOVERNANCE REPORT
OTHER INFORMATION
FINANCIAL REPORT
STRATEGIC REPORT
A summary of the Group accounting policies is set out below, together, where relevant, with an explanation of where changes have 
been made to previous policies on the adoption of new accounting standards in the year. Certain new standards, amendments and 
interpretations to existing standards have been published that are mandatory for the Group's accounting periods beginning on or 
after 01 January 2021 and these have been adopted in the financial statements. 
b. Going concern
The Group has made a loss before tax of £29.5m (2021: £23.4m) and is presently pre-revenue and, as such, has relied upon equity 
and debt funding to progress its development plans. Post year end, the Group has successfully raised £11.5m in equity and £1.5m 
in short term loans.
The Directors regularly review cash flow forecasts to determine whether the Group has sufficient cash reserves to meet its future 
working capital requirements and development plans. The Group’s plans indicate that they need to raise further finance and 
the Directors are confident based on past history of successful fundraising and discussions with investors that the Group will be 
successful in raising these funds. Additionally, they consider they can defer settlement of creditors, reduce short term expenditure 
and obtain short-term finance should there be any delay in completing any such fundraising to allow continuance of their plans. They 
therefore consider it appropriate to prepare the Group’s financial statements on a going concern basis.
However, as at the date of approval of these financial statements, there are no legally binding agreements in place in relation to any 
fundraising or extension of terms of with creditors and as the success of any finance raising is outside the control of the company and 
is thus considered to be a material uncertainty. There can be no certainty that additional funds will be forthcoming which indicates 
the existence of a material uncertainty which may cast doubt about the Group’s ability to continue as a going concern and therefore 
it may be unable to realise its assets and discharge its liabilities in the normal course of business. The financial statements do not 
include the adjustments that would result if the Group was unable to continue as a going concern. 
c. Basis of consolidation
The consolidated financial information includes financial information in respect of the Group and all of its subsidiary undertakings. 
The results of subsidiaries acquired or disposed of during the year are included in the consolidated statement of comprehensive 
in-come from the effective date of acquisition or up to the effective date of disposal, as appropriate. All intra-group transactions, 
balances, income and expenses are eliminated on consolidation. 
The consolidated financial statements consolidate the financial statements of the Company and its subsidiary undertakings (together 
“the Group”) drawn up to 31 December 2021.
A subsidiary is an entity controlled by the Company. Control is achieved where the Company: 
•	
has power over the investee; 
•	
is exposed, or has rights, to variable returns from its involvement with the investee; and 
•	
has the ability to use its power to affect its returns
Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses 
con-trol of the subsidiary. Specifically, income and expenses of a subsidiary acquired or disposed of during the year are included in 
the con-solidated statement of profit or loss and other comprehensive income from the date the Company gains control until the date 
when the Company ceases to control the subsidiary.
Where necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with 
those used by the Group. 
The purchase method of accounting is used to account for business combinations that result in the acquisition of subsidiaries by 
the Group. The cost of a business combination is measured as the fair value of the assets given, equity instruments issued and 
liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the business combination. Identifiable 
assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values 
at the acquisition date. Any excess of the cost of the business combination over the acquirer’s interest in the net fair value of the 
identifiable assets, liabilities and contingent liabilities recognised is recorded as goodwill. 
Inter-company transactions, balances and unrealised gains on transactions between the Company and its subsidiaries, which are 
related parties, are eliminated in full. 
d. Intangible assets-research and development
Development activities involve a plan or design for the production of new and innovative proton beam cancer therapy machines. 
Development expenditure is capitalised only if development costs can be measured reliably, the proton therapy machine is technically 
and commercially feasible, future economic benefits are probable, and the Group has sufficient resources available to complete 
development and to use, lease or sell the asset. The expenditure capitalised includes only the cost of gross direct labour that is 
directly attributable to preparing the asset for its intended use or third-party costs incurred directly on the development activities 
above. Capitalised development expenditure is measured at cost less accumulated amortisation and accumulated impairment 
losses. Other research and development expenditure not meeting the above criteria is recognised in the income statement as 
incurred. Capitalised development costs are amortised over the period from the date the development generates revenue. As at 31 
December 2021 the proton therapy machines are still in the development phase and therefore no amortisation has been recognised

Property, plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses. Where parts 
of an item of property, plant and equipment have different useful lives, they are accounted for as separate items of property, plant 
and equipment.
f. Cash and cash equivalents
Cash and cash equivalents are carried in the balance sheet at cost. For the purposes of the cash flow statement, cash and cash 
equivalents comprise cash on hand, deposits with banks and other short-term highly liquid investment maturities of three months or 
less, net of short term bank overdrafts.
g. Trade and other receivables
Trade and other receivables are recognised initially at the transaction price. They are subsequently measured less any provision for 
impairment in relation to expected credit losses. At each reporting date the Group assesses the expected credit losses and changes 
in credit risk since initial recognition of the receivable and a provision for impairment is recognised when considered necessary.
h. Trade and other payables
Trade and other payables are recognised initially at the transaction price and subsequently measured at amortised cost using the 
effective interest method.
i. Holiday Pay Accrual
A liability is recognised to the extent of any unused holiday pay entitlement which is accrued at the Statement of Financial Position 
date and carried forward to future periods. This is measured at the undiscounted salary cost of the future holiday entitlement.
j. Government Grants
Grants have been received from the UK and US governments to assist with staff furlough and payroll costs during the COVID pandemic. 
The grants are included in the financial statements to the extent that they have been received for the reporting period and confirmation 
has been received that they will become repayable at any point. No other forms of government assistance have been received.
k. Inventories
Stocks are stated at the lower of cost and realisable value. Cost is based on the first-in first-out principle. Net realisable value is 
the estimated selling price in the ordinary course of business, less the estimated costs of selling expenses. Any write down to net 
realisable value is recorded in cost of sales. 
Work in progress is valued at the cost charged for material supplies and the cost charged by sub-contractors for work completed or 
in progress with those sub-contractors. No element of Group overhead or finance cost has been included. 
l. Revenue recognition
During prior periods, the company received an amount of £16.5m for an exclusive distribution agreement issued to Liquid Harmony Ltd. 
This amount is fully repayable if the entity does not complete the development of the products and have regulatory approval in China within 
5 years of the signing of the agreement. As a result of the conditions attached requiring full repayment no revenue, has been recognised. 
m. Income taxes
The charge for current taxation is based on the results for the year as adjusted for items which are non-assessable or disallowed.
Deferred tax is provided using the balance sheet liability method in respect of temporary differences between the carrying amount of 
assets and liabilities in the financial statements and the corresponding tax bases used in computation of taxable profit.
Deferred tax is determined using tax rates that have been enacted or substantially enacted by the balance sheet date and are 
expected to apply when the related deferred tax asset is realised or the deferred tax liability is settled. It is recognised in profit or 
loss except when it relates to items credited or charged directly to equity, in which case the deferred tax is also dealt with in equity.

Deferred tax assets are recognised to the extent that it is probable that future taxable profit will be available against which the

temporary difference can be utilised. Deferred tax assets and liabilities are offset only when they relate to taxes levied by the same 
authority, with a legal right to set off and when the Group intends to settle them on a net basis. 
n. Pensions
The Group makes defined contributions to employees’ personal pension plans. Contributions payable to the employees’ schemes 
are recognised as an expense in the statement of comprehensive income as incurred.
o. Share based payments
The cost of granting share options and other share based remuneration to employees and Directors is recognised through the 
statement of comprehensive income on a straight-line basis over the vesting period, based on the Group’s estimate of shares that 
will eventually vest. These share based payments are measured at fair value at the date of grant by use of an option pricing mode. 
Where the share options only contain service conditions or non-market conditions, a Black – Scholes model is used.  Where the 
share options contain market conditions, a Monte Carlo simulation model is used and reflected the in the fair value of the options 
granted. Details of the assumptions used in those models are included in Note 21 Share based payments.
For equity-settled transactions with non-employees, the costs are recognised through the statement of comprehensive income with 
measurement based on the fair value of goods or services received.
p. Foreign currencies
Transactions in currencies other than the entity’s functional currency are recorded at the exchange rate prevailing at the transaction 
dates. Foreign exchange gains and losses resulting from settlement of these transactions and from retranslation of monetary assets 
and liabilities denominated in foreign currencies are recognised in profit or loss.
The assets and liabilities of foreign entities are translated into sterling at the rate of exchange ruling at the balance sheet date and 
their statements of comprehensive income and cash flows are translated at the average rate for the period. Exchange differences 
arising are transferred to reserves as a separate component of equity.
The Group's presentational currency is GBP.
q. Financial instruments
The Group’s activities expose it primarily to the financial risks of changes in foreign currency exchange rates and interest rates. 
Loans are initially recognised net of associated transaction costs. Subsequent to initial recognition, they are stated at amortised cost. 
r. Loans and Borrowings
Loans and borrowings are recorded at amortised cost using the effective interest method using the expected cash flows attached to 
the financial instrument, with interest-related charges recognised as an expense in finance cost in the statement of comprehensive 
income. In rare circumstances, where cash flows are not possible to be predicted the contractual cash flows over the contractual 
term of the financial instrument are used. 
Where the loan includes a convertible feature, resulting in the possible settlement through issue of shares management consider 
if the conversion would result in a fixed loan amount being settled with a fixed number of shares. Where this is the case, the cash 
flows attached to the financial instrument are discounted at a market rate of interest and the difference between cash proceeds and 
the present value of cash flows being recorded in equity. If the conversion feature does not result in the settlement of a fixed loan 
amount with a fixed number of shares, the financial instrument is assessed as containing a host financial liability held at amortised 
cost and a financial liability held at fair value through profit and loss.
The fair value of the derivative component held at fair value through profit and loss is derived at draw down date and recognised 
separately from the host contract which is held at amortised cost. The derivative component is subsequently measured at fair value 
at each reporting date with the changes being recorded in profit and loss. 
s. Equity instruments
Equity instruments issued by the Group are recorded at the proceeds received, net of direct issue costs.
t. Financial liability and equity 
Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An 
equity instrument is any contract that evidences a residual interest in the assets of the Company after deducting all of its liabilities.
u. Borrowing costs
All borrowing costs are recognised in profit or loss in the period in which they are incurred.
v. Segmental reporting
As the Group’s business activities were not complex, being the development and building of the LIGHT system, and the management 
of a healthcare related property, management reviews information based on different locations and, accordingly, the operating 
segments are based on such a geographical split.
w. Impairment of non-current assets
The Group’s main asset is it development costs which are not yet ready for use. As a result an annual impairment revenue review is

THE ACCOUNTS – GROUP

performed which involves estimating the recoverable amount of the assets, which is the higher of its fair value less costs to sell and 
its value in use, is estimated in order to determine the extent of the impairment loss. Where the carrying value of an asset exceeds its 
recoverable amount (i.e. the higher of value in use and fair value less costs to sell), the asset is written down accordingly. Impairment 
charges are included in profit or loss, except to the extent they reverse gains previously recognised in other comprehensive income. 
x. Leases
Identifying Leases
The Group accounts for a contract, or a portion of a contract, as a lease when it conveys the right to use an asset for a period of time 
in exchange for consideration. Leases are those contracts that satisfy the following criteria:
(a)    There is an identified asset; 
(b)    The Group obtains substantially all the economic benefits from use of the asset; and
(c)    The Group has the right to direct use of the asset. 
The Group considers whether the supplier has substantive substitution rights. If the supplier does have those rights, the contract is 
not identified as giving rise to a lease.
In determining whether the Group obtains substantially all the economic benefits from use of the asset, the Group considers only the 
economic benefits that arise use of the asset, not those incidental to legal ownership or other potential benefits.
In determining whether the Group has the right to direct use of the asset, the Group considers whether it directs how and for what 
purpose the asset is used throughout the period of use. If there are no significant decisions to be made because they are pre-
determined due to the nature of the asset, the Group considers whether it was involved in the design of the asset in a way that 
predetermines how and for what purpose the asset will be used throughout the period of use. If the contract or portion of a contract 
does not satisfy these criteria, the Group applies other applicable IFRSs rather than IFRS 16.
On adoption of IFRS 16, the Group recognised lease liabilities in relation to leases which had previously been classified as ‘operating 
leases’ under the principles of IAS 17 Leases. These liabilities were measured at the present value of the remaining lease payments, 
discounted using the lessee’s incremental borrowing rate as of 1 January 2020. The weighted average lessee’s incremental borrowing 
rate applied to the lease liabilities on 1 January 2020 was 3.0%. The determination of applicable incremental borrowing rates at the 
commencement of new lease contracts also requires judgement. The Group determines its incremental borrowing rates by obtaining 
interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease. The Group considers 
the relevant market interest rate, based on the weighted average of the timing of the lease payments under the lease obligation. 
y. Changes in Accounting Policy
(i) New and amended standards adopted by the Group:
The accounting policies adopted are consistent with those of the previous financial year. New or amended financial standards or 
interpretations adopted during the year are detailed below:
•	
Amendments to IFRS 9 Financial Instruments, IAS 39 Financial Instruments: Recognition and Measurement, IFRS 7 Financial 
Instruments: Disclosures, and IFRS 16 Leases – Interest Rate Benchmark Reform (Phase 2)
•	
Amendments to IFRS 16 Leases – Covid-19-Related Rent concessions beyond 30 June 2021. 
No material impact has arisen as a result of applying these standards.
(ii) The following standards, amendments and interpretations, which are effective for reporting periods beginning after the
date of these financial statements, have not been adopted early:

ANNUAL REPORT 2021
NOTES TO 
THE ACCOUNTS – GROUP
Basic loss per share is calculated by dividing the loss for the period by the weighted average number of ordinary shares in issue 
during the year. This is disclosed on page 109 on the income statement. An alternative to this is the loss per share based on the 
comprehensive loss attributable to the equity holders of the group. This is shown below.
Diluted loss per share
The Group has two categories of dilutive potential ordinary shares - share options and warrants. Both the Group's share options 
and warrants have been excluded from the calculation of diluted loss per share as the entity is loss making and they would be 
anti-dilutive.  These instruments could potentially be dilutive in the future.
Events after reporting period
As at 30 June 2022 the Company had 473,352,211 ordinary shares in issue. Assuming the same loss for the year ended 31 
December 2021 the basic loss per share for the year ended 31 December 2021 divided by the current number of shares in issue 
would decrease to (6.23)p per share.

are charged in the statement of comprehensive income.  One Director (2020: One) accrued retirement benefits during the year. 
A charge of £30,000 (2020: £30,000) has been included in the year for the Directors.

GOVERNANCE REPORT
OTHER INFORMATION
FINANCIAL REPORT
STRATEGIC REPORT
For the purpose of impairment testing of intangible assets, the Group’s continuing operations are regarded as a single cash-
generating unit relating to the development and operation of the LIGHT technology.
The recoverable amount is based on value in use using discounted risk-adjusted projections of the Group’s pre-tax cash flows 
over 10 years and then at a flat rate into perpetuity which is considered by the Board as a reasonable period given the long 
development and expected operational life cycle of the LIGHT technology. The projections include assumptions about the number 
of units to be sold in each financial year, expected unit selling price and production cost, pipeline conversion, competition from 
rival products and pricing policy as well as the possibility of new technology entering the market. In setting these assumptions 
the Directors consider their own past experience, external sources of information (including information on expected increases 
and ageing of the populations in our established markets and the expanding patient population in newer markets), our knowledge 
of competitor activity and our assessment of future changes in the proton beam industry. The 10 year period is covered by 
internal budgets and forecasts. Given that internal budgets and forecasts are prepared for all projections, no general growth 
rates are used to extrapolate internal budgets and forecasts for the purposes of determining value in use. The methods used to 
determine recoverable amounts have remained consistent with the prior year. The weighted average pre-tax discount rate used 
was approximately 12.5% (2020: 12.5%).
As a further check, the market capitalisation is compared to the book value of the Group's net assets: as of the date of this report, 
the market capitalisation is higher than the book value of the net assets.
No impairment was found necessary.
The Group has also performed sensitivity analysis calculations on the projections used and discount rate applied. By their 
nature, the value in use calculations are sensitive to the underlying methods, assumptions and estimates. Consistent with prior 
years, as part of the impairment review process, management has not identified that reasonably possible changes in certain 
key assumptions may cause the carrying amount of the intangible assets to exceed the recoverable amount. At 31 December 
2021, the Group held intangible assets currently still being developed, for which the most sensitive assumption is the probability 
of final technical success, and given their nature, impairment adjustments triggered by future events that have yet to occur may 
be material. In addition, there is a significant risk that impairments recognised in any one period may be subject to material 
adjustments in future periods.

Index Average) per annum.  In May 2021, the Company extended the repayment date of the £10 million loan facility on a rolling 
quarterly basis at the sole discretion of Advanced Oncotherapy through to 11 November 2022. The loan is repayable in cash.
Nerano Pharma is the ultimate parent company of Nerano Capital, a shareholder of the Company. A loan from Nerano Pharma 
of £4 million was received in a prior year and interest accrues at 12 per cent per annum for annual payment or 15 per cent per 
annum if paid at the end of the loan. 
On 28 June 2020, the Company entered into an interest-bearing secured convertible facility with Nerano Pharma for up to $30 
million with the Company being able to issue drawdown requests at any time during the three-year term. 
A rate of interest of 5 per cent. per annum will accrue on all amounts drawn under the Nerano Facility, paid annually in cash on 
each anniversary of the Nerano Facility with the option for the Company to defer payment of that interest until the maturity date of 
the Nerano Facility on 29 June 2023. On the maturity date all amounts drawn under the Nerano Facility and any interest accrued 
thereon shall be repayable by the Company. The Facility provides an option for the Company to voluntarily repay part, or all, of the 
loan (along with any accrued interest) prior to the maturity date. The Nerano Facility is secured on the LIGHT components being 
built in Daresbury and Geneva, associated intellectual property and the property at Harley St. Nerano Pharma will be entitled to 
a share of the profit generated by the Harley Street Centre for up to 15 years. 
Nerano Pharma may convert any amount that the Company has opted to voluntarily prepay during the life of the Nerano Facility 
and at maturity of the Nerano Facility in June 2023, any outstanding loan amounts and interest payable, in each case, into new 
ordinary shares in Advanced Oncotherapy at a price of 25 pence per ordinary share. 
On 17 August 2020 the company drew down $10m of the loan facility. Although convertible, the loan does not meet the fixed 
number of shares for a fixed loan value and therefore the convertible feature has been separated from the host contract and 
recognised as an embedded derivative. The below table shows the movement in the loans. 
The fair value of the embedded derivative was designated as a level 3 in accordance with fair value hierarchy as per financial 
instruments note. The fair value has been determined in conjunction with a third party valuation firm, using  a Monte Carlo 
simulation forecasting the share price at the date the conversion is exercised. The following assumptions were used in the 
calculation of the derivative option:

NOTES TO 
THE ACCOUNTS – GROUP
The Group’s principal financial instruments comprise short-term receivables and payables, lease liabilities and borrowings, short-
term bank deposits and cash. There is currently no material difference between the carrying value of financial assets and liabilities 
and their fair value. The prime objectives of the Group’s policy towards financial instruments are to maximise returns on the 
Group’s cash balances, manage the Group’s working capital requirements and finance the Group’s ongoing operations. 
	
	
	
	
	
	
Capital management	
	
	
	
	
	
The Group's objectives when maintaining capital are:
 
•	
to safeguard the entity's ability to continue as a going concern, so that it can continue to provide returns for shareholders and 
benefits for other stakeholders, and
•	
to provide an adequate return to shareholders.
The Group does not yet have any significant recurring revenues and finances its operations through the issue of new shares 
and loans. The Group’s capital resources are managed to ensure it has resources available to invest in operational  activities 
designed to generate future income.  These resources were represented by £4,260,490 of cash as at 31 December 2021. During 
2021 the Group utilised a number of short and longer term debt facilities in order to provide liquidity to the Group.
Management of financial risk	
	
	
	
	
	
The main risks associated with the Group’s financial instruments have been identified as interest rate risk, liquidity risk, exchange 
rate risk, and credit risk. The Board is responsible for managing these risks and the policies adopted, which have remained largely 
unchanged throughout the year, are set out below.
Interest rate risk
The Group has debts which are the subject of fixed interest rate agreements and, therefore, there is no interest rate risk arising.
Liquidity risk
The Group has financed operations to date through the issue of equity and debt.  All of the financial instruments are measured 
at amortised cost with the exception of the embedded derivative which is measured at fair value.  In connection with its business 
plan, management anticipates additional increases in operating expenses, working capital requirements, and capital expenditures 
in line with the growth of its business, relating to the lease for the assembly site, the purchase of additional inventory, the hiring 
of personnel, and marketing expenses. It expects that those will continue to be funded through a combination of existing funds 
and further issuances of shares, and debt issuances. Thereafter, it is expected that the Group will need to raise additional capital 
and generate revenues to meet long-term operating requirements. Additional issuances of equity will result in dilution to current 
shareholders.

Exchange rate risk
Foreign exchange risk arises when individual Group entities enter into transactions denominated in a currency other than 
their functional currency. The Group's policy is, where possible, to allow Group entities to settle liabilities denominated in their 
functional currency). Where Group entities have liabilities denominated in a currency other than their functional currency (and 
have insufficient reserves of that currency to settle them), cash already denominated in that currency will, where possible, be 
transferred from elsewhere within the Group.
As of 31 December 2021, the Group's net monetary assets by functional currency of the Group’s entities were as follows:

The Directors consider that a movement of 10% of GBP and USD represents the entities exposure to foreign exchange risk and 
do not consider the impact to be material therefore no sensitivity analysis is presented.
Credit risk
The Group is not currently trading and has limited financial assets and therefore the Directors' do not consider that credit risk is 
material. 
Cash at bank is held only with reputable banks with high quality external credit ratings which represents the maximum credit 
exposure. This represents the maximum credit risk to the Group.

 21. Share based payments
(a) Share Options
The Group's shares options are detailed in note a below.  The options in issue are all equity options and vest over a term of 1 to 5 years. 
They do not have performance conditions attached other than the 24m shares options issued on 01 October 2020 under the LTIP scheme.
The vesting conditions attached to the issue are detailed below:
•	
6m on the LIGHT System being fully operational 
•	
6m on first patient treated 	
	
•	
6m on the LIGHT system being certified	
•	
6m if the share price is above £1 for 30 consecutive days. 
The first three of these are non-market conditions and are reflected in the number of options expected to vest in accordance with the 
accounting policy. The vesting period is assessed by management based on their expectation of the conditions being satisfied based 
on the project timeline. Management expect these all to fully vest over a two year period. The inputs in the Black and Scholes model 
are detailed later in this note.
	
The latter item is a non-market condition and is reflected in the fair value of the options in accordance with the accounting policy. The 
inputs in the Monte Carlo simulation are detailed later in this note.

The fair value of services received in return for share options and warrants is measured by reference to the fair value of the share 
options and warrants granted. For issues without market performance conditions, this estimate is based upon a Black Scholes 
model. Where the awards include market conditions, a Monte Carlo simulation model is used. The inputs into the various models 
for options and warrants granted in the year are as follows:
Volatility was determined with reference to the Company's share price movements over a period equivalent to the expected lives 
of the options and warrants retrospectively from the date of issue.

On 23 March 2022, the Company entered into a three-month loan agreement of £1.5 million with Nerano Pharma Ltd, a company 
owned and controlled by Seamus Mulligan, a significant shareholder in the Company, with an interest rate of 1.25 per cent per month

Please indicate on your proxy how you wish your votes to be 
cast in respect of the resolutions to be proposed at the said 
meeting. If you do not indicate how you wish your proxy to 
use your votes, the proxy will exercise his/her discretion both 
as to how he/she votes and as to whether or not he abstains 
from voting. Your proxy will have the authority to vote at his/
her discretion on any amendment or other motion proposed at 
the meeting, including any motion to adjourn the meeting. Any 
power of attorney or other authority under which the proxy is 
submitted must be returned to the Company’s Registrars, Link 
Group, PXS1, 10th Floor, Central Square, 29 Wellington Street, 
Leeds, LS1 4DL. If a paper form of proxy is requested from the 
registrar, it should be completed and returned to Link Group, 
PXS1, 10th Floor, Central Square, 29 Wellington Street, Leeds, 
LS1 4DL to be received not less than 48 hours before the time 
of the meeting.
4.	
In the case of joint holders, the signature of the holder whose 
name stands first in the relevant register of members will 
suffice as the vote of such holder and shall be accepted to the 
exclusion of the votes of the other joint holders. The names of 
all joint holders should, however, be shown. 
5.	
If a member is a corporation, the form must be executed either 
under its common seal or under the hand of an officer or agent 
duly authorised in writing. In the case of an individual the 
proxy must be signed by the appointor or his/her agent, duly 
authorised in writing. CREST members should use the CREST 
electronic proxy appointment service and refer to Note 6 below 
in relation to the submission of a proxy appointment via CREST. 
In each case the proxy appointment must be received with any 
authority (or a notarially certified copy of such authority) under 
which it is signed. 
6.	
CREST members who wish to appoint a proxy or proxies through 
the CREST electronic proxy appointment service may do so for 
the AGM to be held on the above date and any adjournment(s) 
thereof by using the procedures described in the CREST 
manual. CREST personal members or other CREST sponsored 
members who have appointed a voting service provider(s), will 
be able to take the appropriate action on their behalf.
In order for a proxy appointment or instruction made using the 
CREST service to be valid, the appropriate CREST message 
(a “CREST proxy instruction”) must be properly authenticated 
in accordance with Euroclear UK and Ireland Limited’s 
specifications and must contain the information required for such 
instructions as described in the CREST manual. The message, 
regardless of whether it constitutes the appointment of a proxy 
or an amendment to the instruction given to a previously 
appointed proxy must, in order to be valid, be transmitted so 
as to be received by the Company’s agent (lD: RA10) by the 
latest time(s) for receipt of proxy appointments specified in the 
notice of meeting. For this purpose, the time of receipt will be 
taken to be the time (as determined by the time stamp applied 
to the message by the CREST applications host) from which 
the Company’s agent is able to retrieve the message by enquiry 
to CREST in the manner prescribed by CREST. After this time 
any change of instructions to proxies appointed through CREST 
should be communicated to the appointee through other means. 
CREST members and, where applicable, their CREST sponsors 
or voting service providers should note that Euroclear UK and 
Ireland Limited does not make available special procedures in 
CREST for any particular messages. Normal system timings 
and limitations will therefore apply in relation to the input 
of CREST proxy instructions. It is the responsibility of the 
CREST member concerned to take (or, if the CREST member 
is a CREST personal member or sponsored member or has 
appointed a voting service provider(s), to procure that his/her 
CREST sponsor or voting service provider(s) take(s) such action 
as shall be necessary to ensure that a message is transmitted 
by means of the CREST system by any particular time. In this 
connection, CREST members and, where applicable, their 
CREST sponsors or joint service providers are referred, in 
particular, to those sections of the CREST manual concerning 
practical limitations of the CREST system and timings. 
The Company may treat as invalid a CREST proxy instruction 
in the circumstances set out in regulation 35(5) (a) of the 
Uncertificated Securities Regulations 2001. 
Pursuant to regulation 41 (1) of the Uncertificated Securities 
Regulations 2001 (2001 No. 3755) the Company has specified 
that only those members registered on the register of members 
of the Company at close of business on 19 July 2022 shall 
be entitled to attend and vote at the AGM in respect of the 
number of Ordinary Shares registered in their name at the time. 
Changes to the register of members after close of business on 
19 July 2022 shall be disregarded in determining the rights of 
any person to attend and vote at the AGM.
7.	
Under Section 319 of the Act, the Company must answer any 
question relating to the business being dealt with at the meeting 
put by a member attending the meeting unless: 
a.	answering the question would interfere unduly with the 
preparation for the meeting or involve the disclosure of 
confidential information;
b.	the answer has already been given on a website in the form of 
an answer to a question; or
c.	it is undesirable in the interests of the Company or the good 
order of the meeting that the question be answered. 
8.	
The following documents will be available for inspection at the 
Company’s registered office during normal business hours on 
any weekday (Saturdays, Sundays and English public holidays 
excluded) from the date of this notice of the Annual General Meeting

the meeting at least 15 minutes prior to the commencement of the 
Annual General Meeting until its conclusion:

EXPLANATORY NOTES TO 
THE NOTICE OF ANNUAL GENERAL 
MEETING
shares for cash without having to offer them first to existing 
shareholders. In line with common practice, Resolution 14 
therefore seeks authority to empower the Directors to allot 
equity securities for cash other than in accordance with the 
statutory pre-emption rights, in connection with a rights issue 
and other pre-emptive offers and otherwise up to a maximum 
nominal amount of 37,292,063. In addition, there are legal, 
regulatory and practical reasons why it may not always  be 
possible to issue new shares under a rights issue to some 
shareholders, particularly those resident overseas. To cater 
for this, this Resolution also permits the Directors to make 
appropriate exclusions or arrangements to deal with such 
difficulties. Unless renewed, revoked, varied or extended, 
this authority will expire at the conclusion of the next Annual 
General Meeting of the Company to be held in 2023 or 
fifteen months from the date of the passing of the resolution, 
whichever is the earlier.
This year, Resolutions are proposed at the Annual General 
Meeting and the purpose of each of the Resolutions is as 
follows:
ORDINARY BUSINESS
Resolution 1: The Report and Accounts
The Directors will present their report and the audited 
financial statements to 31st December 2021, together with 
the auditors' report therein.
Resolutions 2-10: Re-appointment of retiring Directors
The Articles of Association of the Company stipulate that 
any Director shall only hold office until the conclusion of 
the next annual general meeting following the date of his/
her appointment. Furthermore, the articles require that one 
third of the Directors retire at each Annual General Meeting. 
Corporate Governance guidance recommends that each of 
the Directors retire and offer themselves for re-appointment. 
Biographical details relating to each of the Directors can be 
found on the Group’s website: www.avoplc.com
Resolution 11: Appointment of Auditors
The Company is required to appoint auditors at each 
Annual General Meeting at which accounts are laid before 
shareholders, and for them to hold office until the next such 
meeting. This Resolution proposes RPG Crouch Chapman 
LLP be re-appointed as auditors for the current year.
Resolution 12: Auditors' remuneration
This Resolution authorises the Directors to determine the 
auditors’ remuneration.
SPECIAL BUSINESS
Resolution 13: Authority to allot shares
Section 549 of the Companies Act 2006 stipulates that 
Directors cannot allot shares or rights to subscribe for shares 
in the Company (other than the shares allotted in accordance 
with an employee share scheme) unless they are authorised 
to do so by the shareholders in general meeting. The 
Directors’ general authority to allot shares was granted at the 
General Meeting held on 30 July 2021 which will expire at the 
conclusion of this AGM. Resolution 13 seeks a new general 
authority from shareholders for the Directors to allot Ordinary 
Shares or to grant rights to subscribe for and/or to convert any 
securities into Ordinary Shares up to an aggregate nominal 
value of 37,292,063. The Directors consider it desirable that 
the specified number of Ordinary Shares and/or rights to 
subscribe for and/or to convert any securities into Ordinary 
Shares be increased by 30% so that they can satisfy existing 
warrants and options and allow headroom to more readily 
take advantage of possible equity raising opportunities. 
Unless renewed, revoked, varied or extended, this authority 
will expire at the conclusion of the next AGM of the Company 
to be held in 2023 or fifteen months from the date of the 
passing of the resolution, whichever is the earlier.
SPECIAL RESOLUTION
Resolution 14: Disapplication of pre-emption rights
If the Directors wish to allot any Ordinary Shares for cash 
in accordance with the authority proposed in Resolution 13, 
the Companies Act 2006 requires that new Ordinary Shares 
must generally be offered first to shareholders in proportion 
to their existing holdings. These are the pre-emption rights of 
shareholders. In certain circumstances, it may be in the interest 
of the Company for the Directors to be able to allot some
