    • Data support the potential of INB-100 to induce long-term durable responses in patients with high-risk or relapsed acute myeloid leukemia (AML).
    • Clinical activity observed includes continuing robust durability of relapse-free survival; all three patients in Cohort 1 remain alive and progression-free; ongoing durations of response exceed 12 months and extend beyond 25 months.
    • To date, INB-100 continues to demonstrate a manageable safety profile with no dose-limiting toxicities.

    NEW YORK, Nov. 03, 2022 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company discovering and developing innovative gamma-delta T cell therapies that utilize its DeltEx platform, today announced positive early data from the ongoing Phase 1 trial evaluating INB-100, an allogeneic gamma-delta T cell therapy, in patients with high-risk acute myeloid leukemia (AML) undergoing haploidentical hematopoietic stem cell transplant (HSCT) have been selected for a poster presentation at the 64th American Society of Hematology (ASH) Annual Meeting and Exposition taking place December 10-13, 2022.

    “The patients with high-risk AML undergoing HSCT in Cohort 1 continue to demonstrate encouraging signs of long-term durable responses after a single dose with INB-100. These early signs of long-term durability and progression-free survival demonstrate the potential of INB-100 as a new treatment option in this patient population. Importantly, the safety profile on INB-100 continues to be manageable, and we have not seen dose-limiting toxicities (DLTs) to date, which is encouraging,” said Trishna Goswami, M.D., Chief Medical Officer of IN8bio. “These data suggest that treatment with a one-time allogeneic gamma-delta T cell therapy has the potential to disrupt the treatment paradigm for AML. We look forward to sharing updated data at ASH and additional data at future peer-reviewed conferences.”

    The abstract highlights data from Cohort 1 of the ongoing Phase 1 clinical trial of INB-100 in patients with high-risk AML undergoing HSCT. Three patients have at least 12 months of follow-up, and all remain in morphological complete remission (CR); two patients have remained progression-free for more than two years (26.5 months and 24.2 months) and a third for more than one year (12.5 months) post-transplant at the time of abstract submission. Immune system reconstitution through the first 100 days post-treatment demonstrates continued normal function, including observed elevations in T cells, B cells, and gamma-delta T cells. No DLTs or greater than grade 3 events of acute or chronic graft versus host disease (GvHD), cytokine release syndrome (CRS), or immune effector cell neurotoxicity syndrome (ICANS) have been observed. The most common adverse events (AEs) were constipation, cytomegalovirus (CMV) reactivation, emesis, fatigue, and hypomagnesaemia, the majority of which were Grade 1/2.

    Additional updated data will be presented during the poster session at ASH.

    Details for the ASH 2022 presentation are as follows:

    About the INB-100 Phase 1 Trial
    The Phase 1 clinical trial (NCT03533816) is a dose-escalation trial of allogeneic derived, gamma-delta T cells from matched related donors that have been expanded and activated ex vivo and administered systemically to patients with leukemia following haploidentical HSCT. The single-institution clinical trial is currently being conducted at The University of Kansas Cancer Center (KUCC). The primary endpoints of this trial are safety and tolerability, and secondary endpoints include rates of GvHD, relapse rate and overall survival.
