Purespring Therapeutics Ltd, a gene therapy company developing treatments for kidney diseases, has raised £80 million from private investors to bring its lead product into clinical development. This is the latest in a series of transactions among biotech companies in the kidney disease sector but the first for a preclinical gene therapy. Purespring’s product candidate, PS-002, is an adeno-associated viral vector with a gene payload for the treatment of IgA nephropathy (IgAN), a chronic kidney disease primarily affecting young adults.
