INAB IN8bio Inc

IN8bio (Nasdaq: INAB), a clinical-stage biopharmaceutical company advancing innovative gamma-delta T cell therapies, presented in an oral session details about its robust and reproducible proprietary clinical-scale gamma-delta T cell manufacturing platform across different donor populations, at the American Society of Gene & Cell Therapy (ASGCT) 2024 Annual Meeting.

In an oral presentation titled: “Healthy Donor vs. Patient Manufactured Autologous DeltEx DRI Product; Immunophenotyping Gene Expression,” IN8bio provided novel characterization data demonstrating the reproducibility and robust cellular properties of its clinical-scale manufactured investigational products. These data demonstrate that the manufacturing process results in investigational products with upregulated markers of potency, effector functions and trafficking capabilities, which IN8bio believes represents a significant advancement in the characterization of gamma-delta T cell-based therapies.

“The data presented provide additional insight on the complex gene-expression changes that occur throughout the manufacturing of our gamma-delta T cell products, which demonstrate a consistent profile at the end of manufacturing,” said Dr. Kate Rochlin, Chief Operating Officer of IN8bio. “These new insights into the potency, effector functions, and trafficking changes that occur from initiation to the end of manufacturing in our gamma-delta T cells underscores the reproducibility and robustness of our manufacturing process. The data suggests that the characteristics of the final product are driven more by the manufacturing process than individual donor profiles. We seek to understand how key molecular characteristics allow the optimization of these unique therapies for potentially improved clinical outcomes.”

The study evaluated T cell receptor repertoire and gene-expression changes from apheresis starting material through to final manufactured gamma-delta T cell products, from healthy donors and glioblastoma (GBM) patients enrolled in the INB-200 Phase 1 clinical trial (NCT04165941).

The gamma-delta T cell products demonstrated significant increases in markers of cellular activation and cytotoxicity, with enhanced expression of immune trafficking and stimulation markers, suggesting the potential for potent killing, tissue trafficking and immune cell recruitment in vivo.

The data also revealed highly similar gene expression profiles between gamma-delta T cell products manufactured from healthy volunteers and GBM patients, demonstrating the robustness and reproducibility of the manufacturing process across different donor populations.

About IN8bio IN8bio is a clinical-stage biopharmaceutical company developing gamma-delta T cell-based immunotherapies for cancer patients. Gamma-delta T cells are a specialized population of T cells that possess unique properties, including the ability to differentiate between healthy and diseased tissue. The company’s lead program INB-400 is in a Phase 2 trial in GBM. Additional programs include Phase 1 trials in solid and hematologic tumors, including INB-200 for GBM and INB-100 for patients with hematologic malignancies undergoing transplantation.
