Pharmaxis drug discovery strategy building a biotech powerhouse in fibrosis and inflammation Strategy Achievements to date Drug discovery: Drug discovery:  Improve drug discovery hit rate by:  First in class NASH drug taken to phase 1  Prioritise validated targets  Two further candidates in lead optimisation  Multiple small molecule drugs from in- phase  One lead candidate moving to preclinical house amine oxidase chemistry platform  Develop to phase 1 or 2 Partnering: Partnering:  Create value via:  Licence out to Big Pharma with attractive  In house BD expertise achieves valuable 1 st in class drugs post phase 1 or 2 deal with Boehringer Ingelheim - A$39m  Collaborate to de-risk and accelerate PXS upfront, total potential > A$750m programs  Collaborate on in-licensing programs  Collaboration with Synairgen Research plc for early stage fibrosis program to widen spread of indications, enhance time to value inflection and spread risk 7

SSAO for NASH SSAO inhibitor PXS4728A sold to Boehringer Ingelheim in May 2015 PXS 4728A Boehringer Ingelheim  Excellent partner:  Mechanism based inhibitor of SSAO  Boehringer leaders in metabolic  Small molecule inhibitor of disease semicarbazide-sensitive amine oxidase  / vascular adhesion protein (VAP-1) Industry leading development times   Boehringer responsible for all Important inflammatory pathway in several diseases including NASH and development, and commercialisation activities COPD  Development status:  Competitive deal:   Pharmaxis discovery – patent filed Total potential payments to approval for 2012 2 indications: €418.5m (~A$600m), • acquisition (May 2015): €27.5m  Effective in pre clinical models of NASH (~A$39m) and airway inflammation • commencement of phase 2 and 3:  Phase 1 study reported up to total €55m (~A$80m) • orally bioavailable • filing, regulatory & pricing approvals: • long lasting inhibition after single up to total €140m(~A$200m) dose • second indication: additional total milestone payments (€195m) • progressive dose response  Earn-out payments on annual net sales  Competitors: • tiered percentages starting in high  Genefit – GF505 in Phase 2b NASH single digits  Intercept - OCA (FXR agonist) in • plus potential sales milestones Phase 2b NASH  External validation of PXS drug  Gilead – FXR agonist in pre clinical discovery and ability to negotiate valuable global deals 8

LOXL2 inhibition for NASH & other fibrotic diseases an attractive target and development program Excessive production and linking of  Potential indications: collagen fibres results in fibrosis  NASH / Liver Fibrosis  Pulmonary fibrosis (IPF)  Cancer  Wound healing Fibroblast cells in  Development status: human tissue  Pharmaxis discovery – patent filed 2014  Lead compounds with differentiated PK / PD profile LOXL2 identified (from fibroblasts)  Effective in pre clinical models of fibrosis and cancer  Competitive profile: Excessive ‘cross-linking’ of Collagen fibres  Novel target and mechanism of action collagen fibres, stiffens  Once daily oral drug tissue, causing fibrosis  Complete inhibition of LOXL2 versus partial inhibition by antibody  Low cost of goods Gilead – LOXL2 antibody • Acquired Arresto program $225m pre phase 1 • Now in broad phase 2b trial program • Liver fibrosis; Idiopathic pulmonary fibrosis; Metastatic pancreatic cancer; Myelofibrosis; Solid tumours; Metastatic colorectal cancer 9

LOXL2 for pulmonary fibrosis collaboration with Synairgen Idiopathic Pulmonary Synairgen Fibrosis (IPF) collaboration  IPF primarily affects people over  Access to  the age of 50 Synairgen’s strength in fibrosis  5,000 patients have IPF in biology and respiratory clinical development - BioBank human Australia tissue models technology  100,000 people with IPF in the platform US  expertise at University of  Prognosis is worse than that of Southampton many cancers  Faster time to value appreciation  Two drugs approved recently and partnering points of phase 1  Nintedanib (Boehringer or 2a Ingelheim)  Synairgen to fund pre clinical tox  Pirfenidone (Roche) and phase 1  Need for new therapies  Shares risk and reward based on  Current products expected to investment in program produce global revenues > $1.1  Allows PXS to pursue further billion by 2017 indications in parallel 10
