Purespring is a precision nephrology company pioneering podocyte-targeted, genetically-driven therapies where unmet need is greatest.
Focusing on large and underserved patient populations with both monogenic and non-monogenic disease, our goal is to preserve kidney function and transform the disease trajectory so patients can live fuller, healthier lives.

Kidney disease remains one of humankind’s most underserved disease areas, affecting over 788 million people globally (one in every 10 people) and ranking among the top 10 causes of death worldwide. The WHO estimates it will rank in the top 5 by 2050.
Whilst many disease areas have seen novel therapies reach the market, therapeutic innovation in kidney disease has been lacking, and patients are in dire need of new options. Currently, when patients progress to end-stage renal disease, they are faced with two options: dialysis or kidney transplant. Both of these treatment routes are burdensome for patients and expensive for healthcare systems and society, with costs concentrated in late-stage disease where intervention comes too late.
Recent economic modelling from the Lancet suggests the annual direct costs of diagnosed CKD and renal replacement therapies in in 31 select countries and regions will exceed US $400 bn by 2027.
At Purespring, we are re-imagining gene therapy delivery for kidney diseases, pioneering podocyte-targeted, genetic therapies that act through gene replacement or augmentation to minimise systemic effects and deliver durable efficacy to transform the trajectory of disease for renal patients.

Our proprietary, category defining GlomThera™ platform is designed to enable local administration of lower dose genetic therapies directly to the podocyte – a specialised kidney cell implicated in a majority of glomerular disease – with the potential for durable treatment effects and an improved safety profile.
Our multi-asset pipeline is focused on renal indications affecting large and underserved patient populations.
Our lead programmes target gene replacement or gene augmentation in monogenic and non-monogenic disease, addressing Alport Syndrome and IgA nephropathy (IgAN). PS-003 is advancing toward clinical development in Alport Syndrome, a rare inherited kidney disease with no approved targeted therapies, while PS-002, which has entered first-in-human studies, aims to evaluate a differentiated approach for IgAN patients with durable efficacy and an improved safety profile.
