Purespring Therapeutics Ltd. has received the go-ahead for a phase I/II trial of its investigational gene therapy PS-002 from both the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) and the National Health Service Health Research Authority and Research Ethics Committee.
Gene and cell therapies (GCTs) can target the kidney to treat congenital, acute or chronic diseases affecting this organ. However, its complex structure poses a challenge for these technologies. To be precise and effective in the long term, new approaches should circumvent the specificities of renal tissue, with novel methods of delivery and gene transfer to offer new therapeutic options for patients who lack them.
Purespring Therapeutics Ltd. has raised £80 million (US$104.6 million) in a series B, putting it on course to be the first to take a gene therapy for a kidney disease into the clinic. The money enables the company to move the lead program, PS-002, for the treatment of IgA nephropathy to clinical proof of concept and advance programs in other complement-mediated kidney diseases, and in an undisclosed glomerular kidney disease.

Researchers from Purespring Therapeutics Ltd. and affiliated organizations have presented preclinical data for the adeno-associated vector (AAV) gene therapy PS-001 for the treatment of glomerular disease.
Podocytes are a terminally differentiated cell type located in the glomerulus. Podocyte damage and the subsequent dysregulation of podocyte proteins have been implicated in various kidney disorders. Since gene delivery to podocytes using adeno associated vectors (AAVs) has been challenging due to various technological and physiological hurdles, investigators at Purespring Therapeutics Ltd. developed an AAV gene therapy platform that allowed for effective, specific and safe delivery of transgenes to podocytes.
Scientists behind Purespring Therapeutics Ltd. have made progress in overcoming the problems of accessibility, complexity of structure and diversity of cell types that have held back the use of gene therapy in the kidneys, reporting success in treating nephrotic syndrome in a mouse model of the inherited form of the renal disease.
DUBLIN – Health care investor Syncona Ltd. has founded a new startup, Purespring Therapeutics Ltd., to take gene therapy into the kidney. It is committing £45 million (US$59.6 million) in series A funding, which will support the build-out of the new company and take at least one program into the clinic.
