IN8bio to Present New Positive Clinical Data from Phase 1 Trial of INB-100 at EBMT 2023 Annual Meeting
- Updated data on durability of responses and long-term complete responses (CRs) in leukemia patients treated with INB-100 will be presented; no dose-limiting toxicities have been observed
- New correlative data on immune reconstitution and gamma-delta T cell proliferation for Cohorts 1 and 2 will be presented
NEW YORK, April 11, 2023 (GLOBE NEWSWIRE) — IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company discovering and developing innovative gamma-delta T cell therapies, today announced that new data from the ongoing Phase 1 trial evaluating INB-100, an allogeneic, gamma-delta T cell therapy, in patients with hematologic malignancies undergoing haploidentical stem cell transplantation (HSCT), will be presented at the 49th Annual Meeting of the European Society for Blood and Marrow Transplantation (EBMT), being held in Paris, France April 23-26.
Four patients received dose level (DL) 1 of INB-100 (1 x 106 cells/kg) and two patients received DL2 (3 x 106 cells/kg) as of the abstract data cutoff of December 18, 2022. All four patients who received DL1 remain on study and in durable complete remission (CR), with one patient remaining progression free for nearly three years at 32.2 months and the others remaining progression free for 29.8, 18.1 and 3.8 months respectively. Immune system reconstitution through the first 100-days post-treatment was robust and durable, with observed elevations in T cells, NK cells, and gamma-delta T cells. Updated data from this Phase 1 study will be presented at the meeting on April 23rd, 2023.
Details for the EBMT 2023 presentation are as follows:
Title: INB-100: Relapse Prophylaxis Post-Haploidentical Bone Marrow Transplantation and Cyclophosphamide (Haplo/Cy) by Infusion of Donor-Derived Expanded/Activated Gamma-Delta (γδ) T Cells: A Phase I Trial
Presenter: Joseph McGuirk, DO, The University of Kansas Cancer Center
Abstract #: P239
Date and time: Sunday, April 23, 8:30 a.m. CET
Session: ePoster Viewing
About the INB-100 Phase 1 Trial
The Phase 1 clinical trial (NCT03533816) is a dose-escalation trial of allogeneic gamma-delta T cells from matched related donors that have been expanded and activated ex vivo and administered systemically to patients with leukemia following 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.
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 is currently conducting two investigator-initiated Phase 1 clinical trials for its lead gamma-delta T cell product candidates: INB-200 for the treatment of newly diagnosed glioblastoma and INB-100 for the treatment of patients with leukemia undergoing hematopoietic stem cell transplantation. IN8bio is initiating INB-400, a company-sponsored Phase 2 clinical trial in newly diagnosed glioblastoma following IND clearance in late 2022. IN8bio also has a broad portfolio of preclinical programs focused on addressing other solid tumor types. For more information about IN8bio and its programs, please visit www.IN8bio.com.
