With over 1000 CGT developers worldwide, the FDA expects to approve 10-20 CGT products per year annually from the year 2025. Based on this information, there is an industry emphasis on streamlining the technology transfer process for new products into CDMOs. There are many considerations that are unique to CGT and if discussed early in the NPI process, could help reduce the risk of unplanned disruptions and align expectations in the early stages. This paper presents a common understanding and proposed ownership of these unique aspects, developed via a consensus of CGT sponsor (client) and CDMO participants in the Validation workstream of BioPhorum Cell and Gene Therapy. These recommendations could serve well as pre-established expectations or as an agenda for an NPI–kickoff meeting upon the initiation of a CGT sponsor CDMO relationship.They could also be used to support master supply agreement and quality agreement discussions.
