IN8bio recognizes 4-years in remission for patient treated with INB-200

IN8bio (INAB) 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. IN8bio recently presented updated Phase 1 data from the INB-200 trial at the 2025 American Society of Clinical Oncology 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.
