NewsERS Genomics and Lepton Pharmaceuticals LTD Enter CRISPR/Cas9 License Agreement

July 26, 2022by admin

License allows Lepton, with their proprietary Castling Technology, to develop and commercialize products and services using CRISPR/Cas9 technology

Dublin, Ireland and Zichron Yakov, Israel, 26 July 2022: ERS Genomics Limited (‘ERS’) is pleased to announce a new license agreement with Lepton Pharmaceuticals LTD (‘Lepton”). This is a non-exclusive licensing agreement granting Lepton access to the ERS CRISPR/Cas9 patent portfolio for certain applications.

ERS, co-founded by Dr. Emmanuelle Charpentier, 2020 Nobel Prize winner for gene-editing, provides access to the foundational CRISPR/Cas9 intellectual property. Over 90 patents are held in over eighty countries.

Lepton Pharmaceutical LTD is a biotechnology company developing a proprietary, breakthrough technology (Castling Technology) to substantially improve adaptive cell-mediated immune response (T-cells, CAR-T-cells, NK-cells….)

Dr. Daniel Zurr, CEO of Lepton said: “We are very pleased to establish this relationship and license agreement with ERS Genomics. It will greatly assist us to develop our innovative Castling technology to significantly improve immune cells efficiency and longevity to fight cancer.”

Eric Rhodes, CEO at ERS Genomics added: “Lepton’s Castling technology has great potential to impact the field of immunotherapies and we are pleased to help enable Lepton in pursuing this exciting approach.”

The Castling technology is a proprietary, miRNA-based general technology platform, essentially consisting of the manipulation of miRNA expression to achieve enhanced efficacy and longevity (reduced exhaustion) of cell-based therapies. miRNAs are noncoding RNAs that each affects the expression of hundreds of coding genes. The Castling technology allows, in a single gene editing event in the immune cell (either allogeneic or autologous.)to impact the expression of multitude genes in the

immune-cells once they penetrate the microenvironment of cancer cells. This technology aims to revolutionize the immune cell cancer therapy field,

Financial details of the agreement are not disclosed.
