"This quarter we continued to build upon our deep expertise in γδ T cells, officially welcoming Dr. Polyakova to the team and making progress with our proprietary TCE platform," said William Ho, CEO and co-founder of IN8bio. "It’s also exciting to see the external recognition that the unique properties of γδ T cells and their tissue-specific distribution, "may offer a unique opportunity to eliminate pathogenic cells more precisely and deeply in target organs" as stated in the Nature Reviews article. We believe this platform has the potential to enable a new class of therapeutics for autoimmune diseases and oncology, and we are excited to present our initial animal data by year-end."

Third Quarter 2026 Business Highlights

Strengthened Research and Development Leadership

Oxana Polyakova, Ph.D., joined IN8bio as Senior Vice President of Research & Development in September 2026, bringing 20 years of experience in γδ T cell biology, immunology, oncology, TCE and biologics development.
Dr. Polyakova joins IN8bio from LAVA Therapeutics, a clinical-stage immuno-oncology company developing bispecific γδ T cell engagers, where she served as Chief Scientific Officer (CSO). She previously also served as CSO at LIfT Biosciences. She was Scientific Founder and Head of Discovery at Adaptate Biotherapeutics, a γδ TCE focused spinout of GammaDelta Therapeutics, which was acquired by Takeda. At Adaptate, she designed and led its R&D strategy, established its laboratories and built its R&D team which has a program currently in the clinic. Dr. Polyakova served as the Protein and Molecular Leader at GammaDelta Therapeutics Limited that was also acquired by Takeda.
She will help lead R&D efforts to accelerate IN8bio’s γδ TCE pipeline toward clinical development.

Publication of INB-200 Phase 1 Data in GBM

In July 2026, IN8bio announced the publication of peer-reviewed clinical data from the Phase 1 trial of INB-200 (DeltEx DRI) in patients with newly diagnosed GBM in the Journal of Clinical Oncology(JCO), titled "Intracranial injection of ex vivo expanded and activated gamma-delta T cells engineered with a MGMT-expressing lentivector in patients with primary glioblastoma."

Advancing γδ T Cell Engager Platform (INB-619)

Continued advancing proprietary INB-600 platform of novel pan-γδ TCEs designed to selectively engage and expand γδ T cells to eliminate disease-associated target cells while potentially improving tolerability compared with conventional CD3-targeting TCEs.
Advancing INB-619 through preclinical studies for potential applications in oncology and autoimmune diseases.
INB-619 was included in a review of next-generation immune cell engagers for B cell depletion in autoimmune disease published in Nature Reviews Drug Discovery in October 2026, which noted its ability to activate and expand both tissue-resident Vδ1 and circulating Vδ2 γδ T cells in vitro.
Remain on track to report initial in vivo preclinical data for INB-619 by year-end 2026.
Third Quarter 2026 Financial Highlights

Research and Development (R&D) expenses: R&D expenses were $2.6 million for the three months ended September 30, 2026, compared with $2.1 million for the comparable prior year period. This amount includes non-cash items such as stock-based compensation (SBC) and depreciation of $0.4 million for the three months ended September 30, 2026. The increase was due primarily to preclinical costs associated with the Company’s T cell engager platform.
General and administrative (G&A) expenses: G&A expenses were $2.1 million for the three months ended September 30, 2026, compared with $1.9 million for the comparable prior year period. This amount includes non-cash items such as SBC and depreciation of $0.3 million for the three months ended September 30, 2026. The increase was due primarily to higher spending on professional services.
Net loss: The Company reported a net loss of $4.6 million, or $0.24 per basic and diluted common share, for the three months ended September 30, 2026, compared with a net loss of $3.9 million, or $0.85 per basic and diluted common share, for the comparable prior year period.
Cash position: As of September 30, 2026, the Company had cash of $14.0 million, compared with $10.7 million as of September 30, 2025.
