Presented New Preclinical Data on INB-619 at ACR Convergence 2025

IN8bio presented compelling new preclinical data on INB-619, its CD19 targeting γδ TCE, at the 2025 American College of Rheumatology (ACR) Convergence Meeting. In preclinical systemic lupus erythematosus (SLE) donor models, INB-619 achieved complete elimination of B cells with efficacy equivalent to commercial CD19 and CD20 engagers, including the FDA-approved compounds blinatumomab and mosunetuzumab.
The data showed that INB-619’s selective γδ T cell activation drives deep B cell depletion with minimal cytokine release, confirming the potential for improved safety over conventional CD3-directed engagers in development.
INB-619’s targeted immune activation and cytokine-sparing design could allow for higher doses, deeper B cell depletion and immune reset that has not been observed with other protein engagers to date.
Expanded INB-100 Clinical Trial to Multiple Sites

IN8bio expanded the Phase 1 trial of INB-100 to include The Ohio State University (OSU), diversifying centers and accelerating patient enrollment.
The addition of Sarah A. Wall, M.D., the Director of Clinical Operations for the Transplant and Cell Therapy Program and an expert in elderly patients with leukemias from this leading academic institution, underscores the strong clinical interest in advancing INB-100, a donor-derived, allogeneic γδ T cell therapy in patients with leukemias undergoing haploidentical stem cell transplantation.
William Ho, CEO and co-founder of IN8bio, commented, "During the quarter, we continued to execute on our goal of developing next-generation γδ T cell therapies. Our focus on the novel biology of γδ T cells underscores our advancements along with the strength and versatility of our DeltEx platform. This quarter, we expanded our INB-100 clinical operations to additional sites to accelerate enrollment, and we reported compelling preclinical data at the 2025 ACR Convergence Meeting. Our INB-619 program is a novel and differentiated program in a sea of CD3-based TCE’s that have yet to achieve immune reset in the autoimmune disease setting. We remain focused on delivering the next generation of γδ T cell therapies designed to redefine immune modulation and improve patient outcomes."

Upcoming Anticipated Pipeline Milestones and Events

Updated Phase 1 and 2 data from the INB-200/400 program in newly diagnosed GBM to be presented at the SNO Annual Meeting, November 19-23, 2025
Additional preclinical data from INB-619 γδ T cell engager program in oncology will be presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting, December 6-9, 2025
Third Quarter 2025 Financial Highlights

Research and Development (R&D) expenses: R&D expenses were $2.1 million for the three months ended September 30, 2025, compared with $3.3 million for the comparable prior year period. This amount includes non-cash items such as stock-based compensation (SBC) and depreciation of $0.5 million for the three months ended September 30, 2025. The change was primarily due to a strategic pause on clinical trial-related activities for the INB-400 program last year and personnel-related costs, which followed the Company’s pipeline prioritization announcement in September 2024. The Company continues to prioritize programs demonstrating the strongest clinical signal and commercial opportunity.
General and administrative (G&A) expenses: G&A expenses were $1.9 million for the three months ended September 30, 2025, compared with $2.7 million for the comparable prior year period. This amount includes non-cash items such as SBC and depreciation of $0.4 million for the three months ended September 30, 2025. The change was primarily due to cost savings related to personnel-related costs, director and officer insurance premiums and professional services.
Net loss: The Company reported a net loss of $3.9 million, or $0.85 per basic and diluted common share, for the three months ended September 30, 2025, compared with a net loss of $7.1 million, or $4.49 per basic and diluted common share, for the comparable prior year period.
Cash position: As of September 30, 2025, the Company had cash of $10.7 million, compared with $4.0 million as of September 30, 2024.
