Novel gene delivery technology published and licensed exclusively to Cellinfinity Bio

• MAJESTIC technology allows CRISPR-independent, DNA-free and non-lentiviral gene delivery into diverse cell types with high efficiency and cell viability
• Cellinfinity has exclusively licensed the technology for development of next-generation genetically enhanced cell therapy

WEST HAVEN, Conn. & SAN FRANCISCO--(BUSINESS WIRE)--Cellinfinity Bio, a privately held pioneer biotechnology company developing first/best-in-class cell therapy products against solid tumors and other diseases, today announced the publication of MAJESTIC (mRNA AAV–SB joint engineering of stable therapeutic immune cells), a technology that efficiently and with high cell health introduces genes into human genome, independent of CRISPR and lentiviral methods. This technology is published in Nature Biomedical Engineering on July 10. MAJESTIC has been used to introduce important genes including chimeric antigen receptors into diverse cell types such as CD8 & CD4 T cells, monocytes, NK-cells and induced pluripotent stem cells (iPSCs). Cellinfinity Bio has an exclusive license of the published MAJESTIC technology from Yale University and Professor Sidi Chen’s lab, Founder of Cellinfinity Bio and Associate Professor of Genetics, Yale University.

“Cell engineering with MAJESTIC is a simple two-step process involving: 1) mRNA electroporation to transiently express transposase and 2) AAV vector transduction that introduces novel gene flanked by transposon sequence,” said Sidi Chen. “We show that this technology has strong merits over existing lentiviral-based and CRISPR technologies to generate cell therapy products.”

“Efficient generation of stably engineered immune cells with high viability and activity is critical for cell therapy,” added Premal Patel, M.D., Ph.D., Chief Executive Officer, Cellinfinity. “We intend to employ MAJESTIC in multiple cell types, allowing development of next generation cell therapy against broad ailments.” Cellinfinity holds exclusive rights to the MAJESTIC technology. In addition, the company has licensed other novel cell evolution technologies from Yale, that allow whole-genome gain-of-function and loss-of-function gene screens from the Chen lab.
