NEW YORK, June 09, 2025 (GLOBE NEWSWIRE) -- 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.

Repeated doses of INB-200 demonstrate extended median progression-free survival (mPFS) of 16.1 months, more than double the expected 6.9 months typically observed with the standard-of-care (SOC) Stupp protocol INB-200 is well-tolerated, showing no serious toxicities beyond those typically observed with chemotherapy. Importantly no cytokine release syndrome (CRS), or immune effector cell-associated neurotoxicity syndrome (ICANS) was observed Median PFS in patients receiving multiple doses of INB-200 exceeds the historical median overall survival (mOS) of 14.6 months with the SOC Stupp protocol; notably, four patients remain alive and progression free for a median of over two years Company to host conference call with principal investigator at 8:30am EDT today.
