ProteoDesign announces new Investment led by Ysios Capital and rebrands as Splice Bio

  • ProteoDesign rebrands as Splice Bio to develop novel gene therapies based on its proprietary intein technology.
  • This pioneering platform has the potential to target genetic diseases that cannot be addressed with current gene therapies.
  • Ysios Capital and Asabys Partners join the board of directors as new investors

BARCELONA, September 15, 2020 – Splice Bio, a biotech company based on technology developed in the Muir Lab at Princeton University, announced today a new investment into the Company led by Ysios Capital and joined by Asabys Partners from its fund Sabadell Asabys. This financing round was organized thanks to the support of existing shareholder Caixa Capital Risc. ProteoDesign is rebranding as Splice Bio to reflect on its progress with its proprietary intein platform, based on pioneering research by the company’s co-founders, and its new focus on gene therapy.

The proceeds will be used to develop novel gene therapies for patients that suffer from genetic diseases. The company’s proprietary platform technology has the potential to address two existing limitations of adeno-associated viruses (AAVs) as vectors for gene therapy, both by increasing the size of the cargo gene that can be delivered and by expanding the range of tissues that can be targeted.

“We are thrilled to have closed this financing round and look forward to developing innovative gene therapies to treat patients that suffer from incurable genetic diseases”, said Miquel VilaPerelló, CEO of Splice Bio.

“We are very excited with this new investment that aims to tackle two of the hallmarks of gene therapy today. We are looking forward to contributing to build a great company based on this unique product-enabling platform technology”, commented Joël Jean-Mairet, Managing Partner at Ysios Capital.

“Splice Bio stands out from other programs for the quality of its initial data, and we believe the company has all the ingredients in hand to unlock the full potential of gene therapy. We look forward to continuing our work with the team in the development of this promising technology”, said Sylvain Sachot, Principal at Asabys Partners.
