Creating a valuable and differentiated Exosome Delivery Platform

ReNeuron Group plc (AIM: RENE), a UK based leader in stem cell derived exosome technologies, announces that it has successfully generated in vivo data to exemplify the cellular and tissue targeting capabilities of exosomes produced from its multiple conditionally immortalised producer cell lines. The Company will now look to broaden its capabilities and focus on the functional delivery of specific payloads.

Randolph Corteling, Chief Scientific Officer, commented: "I am pleased to confirm that over the last six months we have generated comparative in vivo data demonstrating distinct organ and cellular targeting capabilities of our proprietary stem-cell derived exosomes, which differentiates our CustomEX™ platform from that of our competitors."

Iain Ross, Executive Chairman, said: "On the basis of this data the Company will now look to broaden its capabilities and, in liaison with partners and collaborators, focus on the functional delivery of specific payloads. We look forward to updating shareholders in due course."

About ReNeuron

ReNeuron has developed a proprietary stem cell-derived, exosome-based, drug delivery platform with customisable cellular targeting capabilities for the delivery of complex drug modalities.

Through the generation of several unique and scalable exosome producer cell lines, our CustomEX™ platform can be optimised for specific tissues targets and payloads leading to improvements in therapeutic outcome and a reduction in off-target effects. ReNeuron offers a delivery mechanism for a variety of payloads such as siRNA, mRNA, proteins, small molecules and genes. Through its conditionally immortalised induced pluripotent stem cell (iPSC) platform, the Company can make allogeneic tissue cells of choice and has the potential to produce exosomes with tissue specific targeting ability.
