During the 2018 summer, 3rd year Masters student Robert Cerchio received the opportunity to intern for Drug Safety Evaluation at Bristol-Myers Squibb in New Brunswick, NJ. Working with the Department of Genetic Toxicology, he established the flow cytometric in vitro micronucleus assay in human lymphoblastoid TK6 cells and evaluated genotoxic potential for 10 drug candidates using this assay. For compounds that tested positive, he further assessed the mechanism of action with the MultiFlow technique, an emerging flow cytometric assay that simultaneously measures multiple biomarkers associated with genotoxicity. This project created a database for comparing the performance of the in vitro micronucleus assay between TK6 cells and Chinese hamster ovary (CHO) cells within a Bristol-Myers Squibb drug domain and would make substantial contributions to the drug discovery/development and safety evaluation. Throughout the internship, Robert learned about the role of esteemed Bristol-Myers Squib toxicologists in drug development as well as networked with other scientists within the industry. To conclude the summer internship, he gave a presentation of his work to the entire Drug Safety Evaluation team highlighting the work he accomplished in the 10-week program.
