Patient with a grade 4, IDH-mutant, MGMT-methylated glioma remains alive and progression-free for four years after receiving treatment with the INB-200 gamma-delta T cell therapy in glioblastoma trial
NEW YORK, NY, USA I June 09, 2025 I IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies for cancer and autoimmune diseases, announced that Patient 009 in the Phase 1 trial of INB-200 for newly-diagnosed GBM has recently reached a significant clinical milestone. The patient, with a grade 4, IDH-mutant glioma, has been in remission and surviving for 4 years having been treated with INB-200. The patient is doing well, has returned to work and has a good quality of life post-treatment with INB-200. Patient 009’s clinical progress and 4-year remission far surpasses progression-free outcomes observed in other clinical trials of IDH-mutant glioma patients.
“Surviving four years without progression in newly diagnosed astrocytoma WHO4 IDH mutated is a significant achievement demonstrating the potential activity of gamma-delta T cells,” said Dr. Burt Nabors, Principal Investigator of the INB-200 trial and Vice-Chair of Research of Neurology and Director for the UAB Division of Neuro-oncology. “This outcome further highlights the potential impact of INB-200 in one of the most aggressive, difficult-to-treat and deadly cancers.”
IN8bio recently presented updated Phase 1 data from the INB-200 trial at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. The results showed that repeated doses of INB-200 demonstrated an extended mPFS of 16.1 months, more than double the expected 6.9 months typically observed with the standard-of-care Stupp protocol in newly diagnosed GBM. INB-200 is the first genetically modified gamma-delta T cell therapy evaluated in GBM and has demonstrated a favorable safety profile and signals of long-term benefit.
“We are thrilled that our study participant has reached this incredible milestone,” said William Ho, CEO and co-founder, IN8bio. “This type of long-term survival and life changing clinical impact is exactly what we strive to achieve at IN8bio. The current standard-of-care for newly diagnosed GBM has not advanced beyond an overall survival of 14-16 months in over two decades. This is a powerful testament to what’s possible when we harness the unique biology of gamma-delta T cells.”
About IN8bio
IN8bio is a clinical-stage biopharmaceutical company developing γδ T cell-based immunotherapies for cancer and autoimmune diseases. 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-100, is focused on acute myeloid leukemia evaluating haplo-matched allogeneic γδ T cells given to patients following a hematopoietic stem cell transplant. The company is also evaluating autologous DeltEx DRI γδ T cells, in combination with standard of care, for glioblastoma in its INB-200 and 400 programs, and advancing novel γδ T cell engagers for potential oncology and autoimmune indications.
