The chief product officer at Mission Bio discussed the company’s Genome Editing Solution.
“[S]ingle cell [analysis] takes us an extra step forward in understanding down to the actual number of cells that have these translocations, which is something bulk techniques cannot show.”
Gene editing approaches to genomic medicine, such as CRISPR/Cas9-based gene editing therapies, hold tremendous potential to treat a wide variety of rare and common diseases by allowing for precise editing of genes of interest through targeted double-strand breaks.1 Although, gene editing approaches are not perfect, and unintended changes to the genome, such as double-stranded breaks in the wrong location and translocations, can occur. Such changes can carry a number of risks, and translocation in particular, also known as chromosomal rearrangement, has been linked to cancer and other harmful effects. As such, companies developing gene editing therapies need to invest substantial time and resources into detecting such changes when evaluating their product candidates in order to ensure optimal safety. Although DNA sequencing carried out with bulk measure sequencing can detect translocations, it has limitations in terms of scale and accuracy. Mission Bio is seeking to address these limitations through its Tapestri Genome Editing Solution, which the company recently updated with a new translocation analysis feature. The company recently shared information about this update at the American Society of Gene & Cell Therapy (ASGCT) 27th Annual Meeting, held May 7 to 10, 2024, in Baltimore, MD.
At the conference, CGTLive® spoke with Vanee Pho, PhD, the senior director of product management, cell and gene therapy, at Mission Bio, to learn more. Pho discussed the importance of detecting translocations caused by gene editing products and how Mission Bio’s technology can help address this need. She also spoke about a presentation given at the conference by Ayal Hendel, PhD, the principal investigator at the Bar-Ilan University in Israel, with whom Mission Bio is working on research related to characterizing off-target genetic changes resulting from CRISPR-based gene editing.2

Bendamustine Is an Effective Alternative to Fludarabine-Based Lymphodepletion in LBCL
December 7th 2024In the wake of fludarabine shortages, lemphodepletion with bendamustine was found to be an effective alternative compared for patients with large B-cell lymphoma being treated with a CD19-directed CAR T-cell therapy.
