Legal Name: Flash Therapeutics
Dr Régis Gayon
Description of the legal entity:
Flash Therapeutics (FTX) is a gene therapy company developing gene and cell-based therapies by leveraging its proprietary lentiviral platform and bioproduction technologies. The Company is built around the lentiviral platform, which includes regular integrative LV and its patented non-integrative LentiFlash® technology. Such platform covers both current gene-addition and future gene-editing needs. The platform technologies will be leveraged not only in expanding a growing portfolio of candidates through the LentiFlash® technology, but also in supporting the development of partnership programs through out-licensing or co-development agreements. Therefore, the TheraLymph project is clearly in line with the business model of Flash therapeutics.
Curriculum Vitae:
Régis Gayon (Male): Viral Vectors Production & Cell Engineering Manager
Régis joined Vectalys in 2005 as head of the Cell Models team. Since September 2012, he is also in charge of production development, purification and concentration of viral vectors, bringing his expertise in cellular biology to ensure performance and reliability of viral vectors produced at Vectalys. As head of the Vectors and Cell Models Teams, and strong of his experience of over 12 years in cellular and molecular biology, he oversees the viral vector production process and its enhancements, as well as manages the generation of new cellular models, from design to delivery, for use in the fields of bioproduction, gene target validation and drug discovery.

Infrastructure and/or major items of technical equipment
Our Lentiviral plaform, producing highly purified and concentrated lentivectors (titer scale of about 1E9 TU/mL) is divided into two parts:
- the first one to produce R&D and preclinical batches of both integrative and non-integrative lentiviral vectors, from small-scale (1mL) to large scale (30mL) batches. This R&D platform is based in our facilities, in Toulouse.
- the second one to produce clinical batches, from 15mL up to 50mL, is expected to become fully operational by the end of 2019, and is being established through a recently signed, three-year partnership with Hospital Saint-Louis, Lariboisière, Fernand-Widal (Assistance Public hospitals of Paris – AP – HP) to develop and produce gene and cell therapy drugs. Additionally, we have launched the building of a second large-scale GMP bioproduction facility, in Toulouse, comprising 3 suites of production. This new facility will be available by the end of 2021.
The whole lentiviral platform includes all the vectorology steps, going from the design of the expression cassette, to the quality controls of the final lentiviral batches. This platform comprises 4 people in gene engineering, 8 people in lentiviral vectors production, and 3 people in quality controls.
