Continued Durable Remissions Reported in Ph 1 Trial of INB-200

Burt Nabors, M.D., Division Director, Neuro-Oncology at the Heersink School of Medicine at the University of Alabama at Birmingham said, “This novel treatment leverages the DNA damage induced by chemotherapy combined with genetically engineered gamma-delta T cells and we believe it represents a significant advancement in the treatment of solid tumor cancers such as GBM,” said William Ho, co-founder and CEO of IN8bio. “Glioblastomas are often classified as cold, immune desert tumors due to their limited immune cell infiltration. For the first time, we have confirmed the infiltration of gamma-delta T cells into these tumors through paired tissue biopsies following treatment with INB-200. We are encouraged by the patient follow-up with repeat dose patients demonstrating a 79% increase in median PFS as compared to 6.9 months as reported by the Stupp regimen and an almost 50% increase in median PFS as compared to the 8.3 months in the three patients treated with only a single dose of INB-200 in Cohort 1. The addition of IN8bio’s DeltEx drug resistant immunotherapy (DRI) gamma-delta T cells show the potential for extending PFS in this difficult-to-treat patient population when INB-200 was administered in combination with the current standard-of-care used to treat newly diagnosed GBM patients.”
