IN8bio Announces New Preclinical Data in Ovarian Cancer to be Presented at ASGCT 26th Annual Meeting

• Preclinical data demonstrates that gamma-delta T cells have the ability to target other solid tumors such as ovarian cancer, supporting the development of these technologies outside of brain tumors
  
• The data suggest that INB-400, a clinical stage genetically engineered gamma-delta T cell therapeutic candidate, has the potential to be developed as a novel therapy for ovarian cancer, offering hope for patients with this devastating disease

NEW YORK, May 02, 2023 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a leading clinical-stage biopharmaceutical company focused on innovative gamma-delta T cell therapies, will present preclinical data showcasing the potential of INB-400 to target ovarian cancer at the American Society of Cell & Gene Therapy (ASGCT) Annual Meeting, in Los Angeles from May 16-20, 2023.

High-grade serous ovarian cancer (HGSOC) is the most common and devasting form of ovarian cancer, comprising approximately 70-80% of deaths. While poly ADP-ribose polymerase inhibitors (PARPi) have improved patient outcomes, recurrence remains a significant obstacle and unmet medical need. INB-400 is an O6-methylguanine-DNA methyltransferase (MGMT) genetically engineered, chemotherapy resistant gamma-delta T cell product that can recognize and kill cancer cells. INB-400 has shown promising results in preclinical studies, demonstrating a powerful synergistic combination of chemotherapy and gamma-delta T cell therapy to eliminate residual cancer cells. The new data to be presented at ASGCT builds on that success, demonstrating the ability of INB-400 to target and kill multiple ovarian cancer cell lines.

"We believe the technology targeting the DNA damage response pathway underlying our INB-400 program has broad applicability across many solid tumor cancers,” said Lawrence Lamb, Ph.D., co-founder and Chief Scientific Officer of IN8bio. "These data demonstrate the potential of gamma-delta T cells to target and kill solid tumor cells outside the brain. We are encouraged by these findings and will continue exploring the potential of INB-400 across a broad range of solid tumors where new treatment options are urgently needed."

Details of the poster presentation are as follows:
Abstract Title: Vd2+ Combination Treatment of Temozolomide + PARP Inhibitor Sensitize Ovarian Cancer Cells for Gamma-Delta T Cell Killing Through NKG2DL Expression
Abstract #: 584
Session: Wednesday Poster Session
Date and Time: Wednesday, May 17, 2023, 12:00 PM PST (3:00 PM EST)

About INB-400
INB-400 is IN8bio’s DeltEx chemotherapy resistant autologous and allogeneic drug resistant immunotherapy (DRI) technology. Allogeneic INB-400 will expand the application of DRI gamma-delta T cells into other solid tumor types through the development of allogeneic or “off-the-shelf” DeltEx DRI technology.

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 (GBM) 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 GBM, which received IND clearance in late 2022. IN8bio also has a broad portfolio of preclinical programs focused on addressing other hematological and solid tumor cancers.
