Lysogene Announces a Research Collaboration With the Weizmann Institute of Science

Regulatory News:

Lysogene (Paris:LYS)(FR0013233475 – LYS), a Phase 3 gene therapy platform company targeting central nervous system (CNS) diseases, today announced that the company has entered into a collaborative research agreement with Yeda Research and Development Co Ltd, the commercial arm of the Weizmann Institute of Science.

The agreement involves collaboration between Lysogene and the lab of Prof. Anthony Futerman at the Weizmann Institute of Science, with the aim of developing a novel AAV gene therapy approach for neuronopathic Gaucher disease, Parkinson disease, and other diseases associated with mutations of the GBA1 gene. Under the terms of the agreement, Lysogene will provide expertise in AAV vector design and production, while the lab of Prof. Futerman will provide glucocerebrosidase variants with enhanced biological properties and conduct biological proof and concept studies. Lysogene has an exclusive option to license the program.

Ralph Laufer, Chief Scientific Officer at Lysogene said: "We are thrilled to start this research collaboration with Prof. Futerman, a leading expert in the field of sphingolipid biology. The Weizmann Institute is one of the world's leading multidisciplinary research institutes, and the source of numerous groundbreaking medical discoveries and technological applications. Lysogene is developing gene therapy approaches for monogenic neurological disorders, including neuronopathic lysosomal storage diseases. This collaboration is a perfect fit with Lysogene’s strategy, providing the opportunity to develop a novel therapy for a rare lysosomal disease, with the potential to expand into neurological diseases with much larger patient populations, such as Parkinson.”
