On February 22, 2022 PharmaCyte Biotech, Inc. (NASDAQ: PMCB), a biotechnology company focused on developing cellular therapies for cancer and diabetes using its signature live-cell encapsulation technology, Cell-in-a-Box, reported the results of an additional, more finely detailed, analysis of the integration site of the cytochrome P450 2B1 gene from the augmented HEK293 cell clone that is used in PharmaCyte’s pancreatic cancer product candidate known as CypCaps (Press release, PharmaCyte Biotech, FEB 22, 2022, View Source [SID1234608833]).

Previous studies that PharmaCyte conducted showed that the cytochrome P450 2B1 gene in the augmented HEK293 cell clone was located on human chromosome 9. As PharmaCyte announced on December 8, 2021, the flanking sequence around the site of integration was sequenced in its entirety. In this new study, PharmaCyte has been able to confirm the previously elucidated structure of the integrated transgene sequence using more data points.
These studies also set the stage for a next step analysis to determine the genetic stability of the cytochrome P450 2B1 gene at the DNA level after multiple rounds of cell growth. This new study was completed by comparing the original Research Cell Bank cells with cells from the Master Cell Bank, and the analysis confirmed that the cytochrome P450 2B1 and the surrounding sequence has remained stable with no changes detected at the DNA level.
