IN8bio to Present Data Highlighting Potential of INB-200 and INB-400 to Treat Patients with Newly Diagnosed Glioblastoma Multiforme at Society for Neuro-Oncology 28th Annual Meeting

November 10, 2023

Company will present “late-breaker” poster detailing updated clinical data from Phase 1 trial of INB-200

Company-sponsored Phase 2 trial of INB-400 to be showcased in Trials-in-Progress (TIPs) poster

NEW YORK, Nov. 10, 2023 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies, today announced that the Company will present two posters at the Society for Neuro-Oncology (SNO) 28th Annual Meeting, taking place November 15-19, 2023, in Vancouver, British Columbia. The posters highlight the potential of IN8bio’s DeltEx Drug Resistant Immunotherapy (DRI), genetically modified and chemotherapy-resistant gamma-delta T cells to treat patients with newly diagnosed glioblastoma multiforme (GBM). The first poster is a TIPs poster detailing the study design for INB-400, the company-sponsored Phase 2 trial and the second will be a “late-breaker” poster providing updated clinical data from the Phase 1 INB-200 trial.

“Having recently initiated enrollment in our Phase 2 trial, we are excited to share details on the study’s design and look forward to providing updates as the trial progresses,” said Trishna Goswami, MD, Chief Medical Officer at IN8bio. “We are encouraged by the safety and preliminary efficacy signal we have seen in our Phase 1 trial treating GBM patients with autologous, genetically modified gamma-delta T cells. Using this approach, we hope to provide a new treatment for patients living with this cancer who currently have few therapeutic options and limited survival.”

Details for the SNO 2023 presentations:

Abstract #: CTIM-42 (Late-breakers)
Title: INB-200: Phase 1 Study of Gene Modified Autologous Gamma-delta (γδ) T Cells in Newly Diagnosed Glioblastoma Multiforme (GBM) Patients Receiving Maintenance Temozolomide (TMZ)

Phase 2 Clinical Trial of INB-400 in GBM
The Phase 2 clinical trial of INB-400 (NCT05664243), an autologous, genetically engineered gamma-delta T cell therapy, is open for enrollment and plans to enroll approximately 40 patients in “Arm A” of the study. The primary endpoint of this arm is the 12-month overall survival (OS) rate, and key secondary endpoints include tolerability, progression-free survival (PFS), overall response rate (ORR) and time to progression (TTP). The University of Louisville and The Cleveland Clinic are the first clinical sites activated to enroll patients.

INB-400 was granted Orphan Drug Designation (ODD) by the FDA in April 2023, marking the first genetically modified gamma-delta T cell therapy to receive this regulatory designation. GBM remains a disease with significant unmet need, with limited treatment options and poor associated outcomes. The treatment for this highly aggressive brain cancer, has remained largely unchanged for more than 18 years, with a median progression-free survival (PFS) of 6-7 months and median overall survival (OS) of only 14-16 months.

About INB-400
INB-400 is IN8bio’s DeltEx 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 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 has initiated a Phase 2 trial of INB-400 in 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. For more information about IN8bio and its programs, please visit
