Paradigm Enters Heart Failure Market
Key Highlights:
Paradigm has expanded its drug development pipeline by in-licensing Pentosan Polysulfate
Sodium (PPS) for the treatment of heart failure from the University of Oslo, Norway
PPS has demonstrated beneficial effects in an established preclinical heart failure model,
specifically:
o improved systolic function of the heart (pressure in the arteries)
o the potential to stop or reverse disease progression in heart failure, addressing an
important unmet medical need
Exciting medical potential in a disease area where mortality from first diagnosis is high,
reaching 50% at five years from diagnosis1
The global market for heart failure drugs is estimated to be US$18 billion per annum2 with
all currently available treatments unable to stop or reverse disease progression
Paradigm to utilise PPS’s well-established safety data to fast-track development under the
FDA 505(b)(2) pathway (drug repurposing)
Melbourne 20 June 2017 Paradigm Biopharmaceuticals Ltd (Paradigm, ASX: PAR) announces the inlicensing of a heart failure patent from the University of Oslo, Norway as it enters the US$18 billion
global heart failure market.
Paradigm has signed a worldwide exclusive in-license agreement for the patent entitled “Inhibitors
of ADAMTS4 or ADAMTS5 for use in preventing or treating cardiac remodelling and chronic heart
failure” from the University of Oslo.
The agreement comes ahead of Paradigm presenting and holding discussions with potential
commercial partners at the 2017 BIO International Convention this week. The convention will be
held from 19-22 June in San Diego, California and attracts more than 16,000 leading innovators and
companies from the biotech industry.
Heart failure is a disease whereby the heart experiences high blood pressure as a result of a
blockage of vessels or a heart attack, that results in damage to the heart muscle. When damaged,

the heart has great difficulty pumping blood to organs such as the lungs, liver and kidneys. To allow
blood circulation to these organs, the heart compensates by changing its shape and the chambers of
the heart. These changes make the heart work harder, causing heart muscle to degenerate further,
eventually leading to death. Mortality is high for patients with heart failure, reaching 50% at five
years from diagnosis1.
The new patent is founded upon compelling preclinical data (peer-reviewed and published) using
Pentosan Polysulfate Sodium (PPS) as the inhibitor of ADAMTS4 versicanase, a key enzyme involved
in the degenerative process in heart failure This data demonstrates that PPS reduced the amount of
ADAMTS4 versicanase activity in a recognised heart failure model.
Studies also showed that PPS treatment improves systolic function of the heart (the amount of
pressure in the arteries during contraction of the heart muscle) in the heart failure model and that it
has the potential to stop or reverse disease progression in heart failure, addressing an important
unmet medical need for patients.

Figures A and B: Preclinical data showing efficacy of PPS in Aortic Banding rat model of heart failure - PPS downregulates
ADAMTS4 activity at the mRNA level (Figure A) in the Aortic banding rat model which translated to reduction of ADAMTS4
enzymatic activity shown by reduction in versican cleavage fragments (Figure B). Versican cleavage fragments also
contribute to cardiac edema (Vistnes et al 2014).
Mr Paul Rennie, Paradigm’s Chief Executive Officer said: “This collaboration with the University of
Olso provides Paradigm with an exciting novel approach to treat heart failure with PPS and provides
an extended portfolio of clinical indications targeted by our drug repurposing business model.”
“We believe that the unique properties of PPS - its anti-inflammatory action and its ability to slow or
stop the tissue degenerative process in heart failure - provides a novel therapeutic approach not
reported in other heart failure pharmaceutical drugs. This is enormously exciting as it means the
product can potentially meet market needs that are not effectively managed by current cardiac
drugs.”
Paradigm will develop PPS for the treatment of heart failure in partnership with the University of
Oslo, with preparation for the clinical development set to commence in the coming months. It is
anticipated that the development program will advance straight to Phase 2 clinical trials, after the
completion of the Company’s Phase 2 Bone Marrow Edema, hay fever, osteoarthritis and Ross River
Clinical Trials .
Given the recent completion of the Phase 2 hay fever trial (results upcoming), the Company will
focus on completing the Phase 2 Bone Marrow Edema clinical trial and commencing the Ross River
clinical trial. Post the completion of these trials Paradigm will commence the Phase 2 pilot heart
failure clinical Trial (n=24) before commencing the Phase 2b heart failure in 2018. Management
believes its cash position, including the anticipated R&D rebate in Q3CY2017, is more than sufficient
to progress all the company's current programs, and commence planning for the upcoming
osteoarthritis and Phase 2 pilot heart failure clinical trials.
Dr Maria Vistnes of the University of Oslo said: “Our studies were the first to report the increased
production of the enzyme, ADAMTS4 versicanase in heart failure. This is a key enzyme involved in
the degenerative process in heart failure. Most importantly, the data demonstrated that PPS
treatment improved contractility of the heart in the pressure-overloaded heart failure model and
was correlated with a reduction of ADAMTS4 versicanase activity.” He added that: “the preclinical
findings firstly shed light on a novel mechanism for heart failure development, and the role of PPS as
a potential new heart failure therapy.”
Heart failure is divided into two categories: heart failure with reduced ejection fraction (HFrEF),
accounting for 50% to 70% of cases and heart failure with preserved ejection fraction (HFpEF).
Professor Tim Martens who is a leading cardiothoracic surgeon at the Loma Linda Medical Centre at
Los Angeles and Paradigm’s cardiology consultant in the clinical development program was very
encouraged with Dr Vistnes’ data and remarked that: “Currently, there are no registered heart
failure pharmaceutical agents that directly target the destructive enzymes that change the shape
and size of the damaged heart (extracellular matrix remodelling) in the transition to heart failure
and it will be very interesting to see if PPS demonstrates protective and beneficial effects in patients with
heart failure with HFpEF as well as those with HFrEF. There is still an unmet need to effectively treat
heart failure patients with HFpEF.”
Paradigm is further encouraged of the potential of this new heart failure indication as there has
been increasing research connecting the use of oral non-steroidal anti-inflammatory drugs (NSAIDs,
e.g. ibuprofen) to increased risk of heart failure3. The peer-reviewed study recently published in the
British Medical Journal (http://www.bmj.com/content/357/bmj.j1909 ) concluded that: “All NSAIDs,
including naproxen, were found to be associated with an increased risk of acute myocardial
infarction.” Management believe that PPS’s well-documented safety profile and known antiinflammatory properties will make it an excellent new treatment in the heart failure, thus offering a
solution to the potential issue of using NSAIDs under certain circumstances.
ADDRESSABLE MARKET: The global heart failure market is estimated to currently be US$18 billion4
per annum and is made up of the six main treatments that address conditions associated with heart
failure: Statins US$13.1billion, Clopidogrel bisulphate US$1.8 billion, Beta-blockers US$1.55 billion,
Ace inhibitors US$0.47 billion, Aspirin US$0.54 billion, Vitamin K antagonist US$0.5 billion.

The total cardiovascular disease market, which includes hypertension, dyslipidemia, and thrombotic
events, is set to grow from $129.2 billion in 2015 to $146.4 billion by 2022, at a very modest
compound annual growth rate of 1.8%, according to business intelligence provider GBI Research5.
There are numerous blockbuster drugs aimed at the heart failure market that have come off patent
with the most well-known being Lipitor (Warner-Lambert then Pfizer) which was first approved in
1997. Whilst under patent protection it was the highest-selling drug of all time, with worldwide sales
peaking in 2006 at more than US$13 billion a year6. AstraZeneca’s Crestor (rosuvastatin), generated
peak sales of around $7 billion in 2011, however revenues are expected to drop sharply following
the expiration of its patent on July 8, 2016.7
Current standard of care and therapeutics used for heart failure patients include ACE inhibitors,
calcium antagonists, angiotensin receptor blockers, beta blockers and diuretics.
