Paradigm Biopharmaceuticals Ltd (ASX:PAR) is an Australian biopharmaceutical company focused on repurposing the drug pentosan polysulphate sodium (PPS) for the treatment of inflammation.


Paradigm Shift


Established drugs can be repurposed for new clinical indications for unmet medical needs when protected by strong intellectual property. Historical drug safety data and existing manufacturing ‘know-how’ can fast-track clinical development and reduce commercialisation costs for repurposed drugs.


Understanding complexity

Life is complex! For every diagnosis, there are multiple factors and biological interactions involved. We develop therapeutics targeting multiple pathways involved in injury or on the road to disease producing better outcomes for patients.


We develop therapeutics targeting multiple pathways involved in injury

Our focus

Pentosan Polysulphate Sodium (PPS)

We focus on PPS because this FDA approved drug has a long history of safety and efficacy in treating interstitial cystitis and deep vein thrombosis. Our patents cover new applications in bone marrow edema (BME) and respiratory disease.



Inflammation is a complex biological response to injury, infection or allergy, which has short and long term components mediated by factors produced by immune cells.
