November 2017 Drug Repurposing Strategy Much lower cost, accelerated timeline, lower risk and with higher rates of success Lower cost: average development cost of ~US$30-50m compared to US$1.3bn for de novo development 1 Faster: FDA 505(b)(2) pathway leveraging previous clinical efforts, which accelerates the development timeline Lower risk: safety already established so less chance of failure (safety issues account for 30% of clinical failures 1) Higher success rates: 25% chance of successful commercialisation compared to 10% for de-novo drugs 1 Repurposed drugs have the same potential to reach blockbuster drug status as de novo drugs Standard clinical development1,2 10-17 year process Discovery & pharmacology 2 3 years Preclinical testing Phase I clinical trials 5 6 years Phase II clinical trials Phase III clinical trials 2 6 years Regulatory approval 1 2 years Paradigms drug repurposing timeline Often only 1 pivotal Phase II trial Can use RWE open label case studies 1 pivotal Phase III trial for each indication Regulatory approval

At six weeks after the initiation of PPS treatment: Pain 38 out of 45 patients (84.4%) showed a reduction in pain; Function 38 out 45 patients (84.4%) showed an improvement in knee function; Patient A MRI Pre PPS Treatment Pre treatment Scores High NRS Pain Score = 8 Lysholm Score: 37 (Poor knee function) BME Lesions Joint Space Effusions 6 Investor Presentation Patient A MRI Post PPS Treatment Post Treatment Results Complete resolution of BME lesions and effusions Pain NRS = 0 (pain resolved) Lysholm Score: 65 (Fair knee function) November 2017 Osteoarthritis with Bone Marrow Lesions Osteoarthritis - A blockbuster indication with no effective treatments Osteoarthritis and bone marrow lesions BML are commonly associated with OA and have been linked to early onset of OA and joint cartilage degeneration. 1 BML sustains inflammation and the release of MMPs and ADAMTS-5 enzymes, causing cartilage degeneration

Resolution of the BML, reduces inflammation and promotes joint health Patients treated with PPS have reported statistically significant improvement in pain and function Osteoarthritis is the most common form of arthritis, affecting over 31 million people in the United States, with over 36 million outpatient visits and 750,000 hospitalisations per year. 2 Source: 1. The occurrence and progression of BMLs have been shown to be associated with progression to osteoarthritis and joint pain (Osteoarthritis and Cartilage 2012, 20:1514-1518) and (Rheumatology 2010, 49:2413-9). 2. http://ard.bmj.com/content/annrheumdis/early/2017/07/12/annrheumdis-2017-211396.full.pdf 3.

Current therapies treat the symptoms of osteoarthritis and bone marrow edema lesions but prolonged use results in undesirable side-effects. It is widely accepted that NSAIDs and corticosteroids are contraindicated having a detrimental effect on the metabolism of bone and cartilage. Opioids are widely misused globally as patients form serious addictions whilst mitigating pain. 1 ZILOSUL treats the underlying pathology of osteoarthritis by reducing inflammation, resolving the bone marrow edema lesions and down regulating cartilage degrading enzymes (MMPs and ADAMTS-5).

No approved treatment for severely debilitating viral infection Viral Arthritis Alphavirus infections result in the clinical symptoms of joint and muscle pain, fever and joint inflammation. Ross River Virus (RRV) and Chikungunya (CHIKV) are mosquitotransmitted arthritogenic alpha viruses that cause epidemics of severe musculoskeletal disease in many countries. No effective treatment, with sufferers left incapacitated Symptoms can persist for a number of years Ross River Virus & Chikungunya Virus Paradigm acquired the patent from the Institute for Glycomics research at Griffith University. The patent claims the use of PPS to treat alphaviruses, including Ross River Virus (RRV) and Chikungunya Virus (CHIKV). Potential interest from the US Department of Defense to codevelop for treating CHIKV 12 Investor Presentation Chikungunya cases ,USA November 2017 Viral Arthritis: Clinical Timeline Potential to gain Orphan status, resulting in fast-tracked clinical development Pre-clinical studies have been conducted by the Institute of Glycomics at Griffith University. The results suggested that: PPS significantly alleviated the severity of disease and reduced both the inflammatory response and the loss of articular cartilage; PPS has the potential to treat both acute and chronic symptoms associated with mosquito transmitted alphavirus infections (Ross River virus (RRV) and chikungunya virus (CHIKV); There currently is no effective disease modifying treatment for RRV or CHIKV. 30 patients with RRV-arthralgia (joint pain) already treated with PPS under the TGA Special Access Scheme demonstrating tolerability and potential clinical effects Phase 2 Clinical Trial PPS to treat RRV and CHIKV Queensland Government have provided a A$300,000 grant for Ross River research Paradigm to embark on two Phase 2 clinical trial to develop PPS for the treatment of RRV-and CHIKV-induced arthritis and arthralgia Potential for Fast-Track /Breakthrough/Accelerated Approval 2017 Clinical development timeline Proof of concept study under SAS (n=30) Q1 Q2 Q3 2018 Q4 Q1
