IN8bio to Present New Preclinical Data on Novel Gamma-Delta CAR Platform Candidate at AACR Annual Meeting 2024

March 5, 2024

  • New preclinical data demonstrating proof-of-concept for the non-signaling gamma-delta T cell CAR (nsCAR) platform candidate targeting CD-33 and CD-123 will be presented.

  • The platform has demonstrated the ability to target cancer cells while sparing healthy tissue when both express the CAR-targeted antigens, which could be used for previously “undruggable” solid and liquid tumor targets.

NEW YORK, March 05, 2024 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB) a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies, today announced the presentation of new preclinical data for its non-signaling gamma-delta T cell based Chimeric Antigen Receptor T cell (CAR-T) platform, INB-300. The data will be presented at the 2024 American Association for Cancer Research (AACR) Annual Meeting, being held April 5-10, 2024 in San Diego, California.

The current generation of CAR-T technology eliminates the target antigen regardless of whether it is expressed on tumor or healthy tissue. IN8bio's nsCAR platform, INB-300, uses the CAR to traffic and bind to cells expressing the target and leverages the natural innate immune recognition abilities of gamma-delta T cells to distinguish between tumor and healthy tissue. This allows the cells to selectively eliminate cancer cells while leaving healthy cells intact, even when both express the CAR-target.

“We're excited to share this new data from our nsCAR platform, INB-300, which enables next-generation precision CAR-T therapy by selectively targeting leukemia cells while preserving healthy tissues,” said Lawrence Lamb, Ph.D., co-founder and Chief Scientific Officer, IN8bio. “We are using gamma-delta T cells to treat a wide variety of cancers, including myeloid malignancies and solid tumors, where current CAR-T therapy has historically faced significant challenges due to on target, but off tumor toxicities. We look forward to advancing our pipeline of novel gamma-delta based nsCAR therapies for patients with significant unmet need.”

About INB-300
INB-300 is a non-signaling CAR (nsCAR) gamma-delta T cell platform with several preclinical product candidates, including the INB-330 program against AML targets, that combine our expertise in gamma-delta T cells and genetic engineering. These nsCAR constructs lack signaling domains in order to take advantage of the unique properties of gamma-delta T cells to differentiate between healthy and tumor tissues. IN8bio is advancing new nsCAR constructs against multiple targets to treat both solid and liquid tumors.

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 glioblastoma multiforme (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.

Forward-looking statements in this press release include, but are not limited to, statements regarding the ability of IN8bio’s nsCAR platform to use the innate immune recognition of gamma-delta T cells to selectively targeting leukemia cells while preserving healthy tissues; IN8bio’s ability to use gamma delta T cells to treat a wide variety of cancers, including myeloid malignancies and solid tumors; and IN8bio’s ability to advance its pipeline of novel gamma-delta CAR-T therapies. IN8bio may not actually achieve the plans, intentions, or expectations disclosed in these forward-looking statements, and you should not place undue reliance on these forward-looking statements. Actual results or events could differ materially from the plans, intentions, and expectations disclosed in these forward-looking statements as a result of various factors, including: risks to site initiation, clinical trial commencement, patient enrollment, and follow-up, as well as IN8bio’s ability to meet anticipated deadlines and milestones, presented by public health crises as well as rising inflation and regulatory developments; uncertainties inherent in the initiation and completion of preclinical studies and clinical trials and clinical development of IN8bio’s product candidates; the risk that IN8bio may not realize the intended benefits of its DeltEx platform; availability and timing of results from preclinical studies and clinical trials; whether the outcomes of preclinical studies will be predictive of clinical trial results; whether initial or interim results from a clinical trial will be predictive of the final results of the trial or the results of future trials; the risk that trials and studies may be delayed and may not have satisfactory outcomes; potential adverse effects arising from the testing or use of IN8bio’s product candidates; expectations for regulatory approvals to conduct trials or to market products; IN8bio’s reliance on third parties, including licensors and clinical research organizations; and other important factors, any of which could cause our actual results to differ from those contained in the forward-looking statements are described in greater detail in the section entitled “Risk Factors” in our Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (SEC) on November 9, 2023, as well as in other filings IN8bio may make with the SEC in the future.
