    • Data demonstrate the ability of single and repeat doses of INB-200, DeltEx drug-resistant immunotherapy (DRI) gamma-delta T cell therapy, to induce T cell persistence and a sustained immune response.
    • A treated patient, with paired tissue biopsies, demonstrated infiltration of gamma-delta T cells 148 days following a single administration in Cohort 1.
    • Updated patient, survival and enrollment data from the ongoing INB-200 study to be presented at the Society for Neuro-Oncology (SNO) Annual Meeting on November 17, 2023 from 7:30 PM – 9:30 PM PT (Abstract Number: CTIM-42).

    NEW YORK, Nov. 06, 2023 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a leading clinical-stage biopharmaceutical company focused on innovative gamma-delta T cell therapies, today presented new biological correlative data from the ongoing Phase 1 clinical trial of INB-200 targeting newly diagnosed glioblastoma multiforme (GBM) in a poster presentation at the Society for Immunotherapy of Cancer’s (SITC) 38th Annual Meeting.

    Chemotherapy has remained a mainstay of solid tumor treatment. Alkylating agents such as temozolomide (TMZ) can directly kill chemotherapy-sensitive GBM cells but can also sensitize chemotherapy resistant tumor cells to immune recognition by upregulating stress-associated NKG2D ligands (NKG2DL) to drive immunogenicity. Unfortunately, the lymphodepleting effects of chemotherapy, such as TMZ, also kills T cells, and prevents an effective immune response to these stress targets. IN8bio’s DeltEx DRI gamma-delta T cells are designed to be resistant to chemotherapy, allowing them to remain functional and be used in combinations to create a strong synergistic tumor cell killing impact.

    “Gamma-delta T cells are important in immune responses and their high levels are known to correlate with improved survival outcomes. Efficient immune reconstitution is pivotal for favorable outcomes in cancer patients. This new analysis sheds light on how our DeltEx DRI gamma-delta T cell approach may induce durable persistence and immune responses,” said William Ho, Co-founder and CEO. “These important insights will help inform the ongoing development of our DeltEx DRI therapies across a variety of solid and hematological tumors.

    These data demonstrate that the lymphodepleting effects of chemotherapy results in a globally suppressed immune system where the DeltEx DRI gamma-delta T cells can strengthen the immune response and potentially broadly eliminate cancer cells. Furthermore, conventional standard-of-care can act as a long-term lymphodepleting agent, an important component for the development of allogeneic and potentially ‘off-the-shelf’ cellular therapies. In June 2023, IN8bio presented positive data from the Phase 1 study of INB-200 in an oral presentation at the American Society of Clinical Oncology (ASCO) 2023 Annual Meeting. The Company will present updated patient, survival and enrollment data from the study at the Society for Neuro-Oncology (SNO) Annual Meeting taking place November 15-19, 2023.

    About INB-200
    INB-200 is a genetically modified autologous drug resistant immunotherapy (DRI) product candidate for the treatment of solid tumors. This novel platform utilizes genetic engineering to generate chemotherapy resistant gamma delta T cells which can be administered concurrently with standard-of-care treatment in solid tumors. This is a powerful, synergistic treatment approach enabling gamma-delta T cells to persist in the presence of chemotherapy, and maintain their natural ability to recognize, engage and kill cancer cells.

    INB-200 is the first genetically engineered gamma-delta T cell therapy to be administered to patients with solid tumors and our initial indication is in GBM.

    About IN8bio

    IN8bio is a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of gamma-delta T cell product candidates for solid and liquid tumors. 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. IN8bio’s DeltEx platform employs allogeneic, autologous, iPSC and genetically modified approaches to develop cell therapies, designed to effectively identify and eradicate tumor cells.

    IN8bio has initiated a Phase 2 trial of INB-400 in glioblastoma (GBM) at multiple centers across the United States and has two ongoing Phase 1 trials in solid and hematological tumors, including INB-200 for GBM and INB-100 for patients with hematologic malignancies undergoing transplantation. IN8bio also has a broad portfolio of preclinical programs focused on addressing other hematological and solid tumor cancers.
