This is a type of medicine that works by delivering genes into the body. One strategy for simplifying, and thus reducing cost, during lentivirus production is to convert the lentivirus-producing cell line from the 'host cell' or chosen mammalian cell line, which require transient transfection of multiple plasmids, into a 'packaging' cell. The human embryonic kidney 293 cell line (HEK293) is traditionally used for efficient vector production. The CAR-T cell product must be generated individually for each patient, but the vector by which CAR has been encoded can be made in large quantities and stored at -80 for 4 years. The facility in Shanghai's Zhangjiang Cell Therapy Park is the location for all of Jinwei's lentiviral . Lentiviral supernatant was produced after triple transfection of the HEK293T cell line The transgene sequence is flanked by long terminal repeat (LTR) sequences, which facilitate integration of the transfer plasmid sequences into the host genome A genomic insertion site analysis of the lentiviral vector was performed on Kymriah products from 14 . these therapies are considered expensive, with list prices of 475,000 usd for kymriah, 373,000 usd for yescarta (a gammaretroviral gene-modified cell therapy product for blood cancers) and an announced likely price of 1.8 m usd for zynteglo; this can be partly attributed to the high manufacturing costs of these complex therapies [ 5, 6] and the .
