NEW YORK, Aug. 07, 2025 (GLOBE NEWSWIRE) -- IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta T cell therapies for cancer and autoimmune diseases, today reported financial results and business highlights for the second quarter ended June 30, 2025. Key Highlights: Durable Four-Year PFS Milestone in Glioblastoma: A patient in IN8bio's INB-200 clinical trial has now surpassed four years without progression, a significant clinical milestone in front-line, grade IV glioblastoma (GBM), demonstrating the potential for extended overall survival and the durability of IN8bio’s therapy. Positive Clinical Data Presented at ASCO 2025: IN8bio presented positive new data showing that GBM patients receiving multiple doses of INB-200 achieved mPFS of 16.1 months as of May 31, 2025, more than double the 6.9 months typically observed with the standard-of-care Stupp protocol.40% of patients receiving multiple doses remain progression-free for over 18 months with no significant toxicities observed as of May 31, 2025. Award for Innovative Cell Therapy Manufacturing: The Company was recognized with the Host Region USA East Abstract Award at the ISCT 2025 Annual Meeting for its DeltEx™ platform. IN8bio showcased its robust manufacturing processes and scalable technology platform, essential for advancing cell therapy treatments with consistency and operational efficiency. New Preclinical Data in Autoimmune Diseases: IN8bio presented exciting new preclinical results at ASGCT 2025 for its innovative gamma-delta T cell engager (INB-619). INB-619 demonstrated complete, targeted depletion of harmful B cells in lupus samples without significant inflammatory cytokines, representing a potentially safer immunotherapy alternative with the ability to drive deeper B cell depletion. William Ho, CEO and co-founder, IN8bio, commented, “We believe this quarter clearly demonstrates our ability to deliver transformative outcomes in cancer and autoimmune disease. We had an oral presentation at ASCO, reached a remarkable four-year PFS milestone in a grade IV glioblastoma patient, demonstrated the potential of our T cell engager platform to treat autoimmune diseases, and highlighted our robust cell therapy manufacturing capabilities. We’re proud of these continued accomplishments, which demonstrate our ability to be a leader in gamma-delta T cell therapies and highlight our potential to help transform the treatment of cancer and autoimmune disease. We’ve also extended our runway into June 2026.” Upcoming Anticipated Pipeline Milestones and Events Update on enrollment in INB-100 expansion cohort in leukemia patientsGlioblastoma clinical update from INB-200 and INB-400 clinical trialsAdditional preclinical data from INB-619 T cell engager program for cancer and autoimmune diseases in 4Q25 Second Quarter 2025 Financial Highlights Research and Development (R&D) expenses: R&D expenses were $2.5 million for the three months ended June 30, 2025, compared with $5.2 million in the prior year.
