IN8bio Presents Positive Data Update from Induced Pluripotent Stem Cell (iPSC) Platform at the Society for Immunotherapy of Cancer (SITC) 38th Annual Meeting

• This data represents a step forward in developing next-generation ‘off-the-shelf’ iPSC derived gamma-delta T cells. Our proprietary expansion methods are serum and feeder-free and have the potential to produce billions of iVδ1 T cells.
• IN8bio's iVd1+ subtype cells have an expression profile linked to a low risk of cytokine release syndrome (CRS) and have shown strong cancer-killing abilities against various solid and liquid cancers.
• Showcases the capability to manufacture specific gamma-delta T cell sub-types using a process that can be scaled for GMP- manufacturing as a potentially ‘off-the-shelf’ platform for allogeneic cell therapy.

NEW YORK, Nov. 03, 2023 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a leading clinical-stage biopharmaceutical company focused on innovative gamma-delta T cell therapies, today presented new positive preclinical data from its induced pluripotent stem cell (iPSC) gamma-delta T cell platform at the Society for Immunotherapy of Cancer’s (SITC) 38^th Annual Meeting (Abstract #: 637 in Exhibit Halls A and B1). The data represents a significant advance in the development of the INB-500 iPSC program towards the development of allogeneic gamma-delta T cell therapies.

“Our deep understanding of gamma-delta T cell biology allows for significant ex vivo expansion capabilities,” said William Ho, Co-founder and CEO. “We have successfully developed and utilized a robust serum and feeder-free process for generating iPSC derived gamma-delta T cells, representing an important step towards developing a truly allogeneic ‘off-the-shelf’ gamma-delta T cell source for therapeutic development.”

The presented data underscores the platform’s ability to reprogram donor cells into iPSCs, expand them, and guide their differentiation into gamma-delta T cells through IN8bio’s proprietary process, which can be scaled for full GMP manufacturing. Notably, the platform enables the differentiation into both Vd1+ and Vd2+ cell subtypes using cell-type specific processes. The iPSC-derived gamma-delta T cells underwent comprehensive characterization, encompassing morphological analysis, cell surface markers and functional assessment via tumor cell killing assays. Key findings include:
