Rhea-AI Filing Summary

IN8bio, Inc., a clinical-stage biopharmaceutical company focused on γδ T cell therapies, reported results for the second quarter ended June 30, 2026. The company recorded a net loss of $4.8 million, or $0.25 per share, compared with a net loss of $5.1 million, or $1.24 per share, a year earlier. Research and development expenses were $2.5 million and general and administrative expenses were $2.4 million. Cash was $18.0 million as of June 30, 2026, compared with $13.2 million in the prior-year period.

IN8bio highlighted progress across its pipeline, including advancing INB-619, a CD19-targeting γδ T cell engager, into IND-enabling studies, with initial in vivo preclinical data expected in the second half of 2026. Updated data from the DeltEx DRI glioblastoma program showed median progression-free survival of 13.0 months versus 6.6 months for standard-of-care and median overall survival exceeding 19.5 months versus 13.2 months. Additional translational analyses showed an 18-fold increase in intratumoral CD8+ T cells and a 90% reduction in immunosuppressive granulocytes after repeated DeltEx DRI dosing.

Filing Explained

At June 30, 2026, cash was $17,956 thousand and 9,853,121 common shares were outstanding, versus $27,092 thousand and 9,766,132 at year-end.

Form 8-K reports specified material events; Item 2.02 here covers results of operations and financial condition. On August 6, 2026, IN8BIO furnished its unaudited second-quarter results for the period ended June 30, 2026.

The period-end balance sheet reports cash of $17,956 thousand, down from $27,092 thousand at December 31, 2025, and 9,853,121 issued and outstanding common shares, up from 9,766,132. For existing common holders, the visible structural change is a lower reported cash balance and a larger issued share base, although the filing does not identify the cause of the share-count change.

The filing separately reports 490,000,000 authorized common shares and does not state a transaction-specific dilution percentage or proceeds amount, so the share-count change cannot be tied to a financing from this disclosure alone.

The next named resolution path is a future company report on FDA discussions concerning potential regulatory pathways for the DeltEx DRI glioblastoma program.

Increase in intratumoral CD8+ T cell density 18-fold Observed in spatial proteomics after repeated DeltEx DRI dosing in GBM
gamma-delta (γδ) T cell engagers medical
"developing innovative gamma-delta (γδ) T cell therapies and γδ T cell engagers"
cytokine release syndrome (CRS) medical
"potentially reducing toxicities including cytokine release syndrome (CRS) and infections"
An excessive immune reaction in which the body’s defense system releases large amounts of inflammatory signals (cytokines) all at once, like an overactive alarm system that triggers too many responders and causes collateral damage. It matters to investors because this side effect can halt clinical trials, prompt safety warnings or recalls, and increase development costs and regulatory scrutiny for drugs or therapies, affecting a company’s valuation and future revenue prospects.
median progression-free survival (mPFS) medical
"more than doubled expected median progression-free survival (mPFS) in newly diagnosed GBM"
Median progression-free survival is the middle value of time, in a group of patients in a clinical trial, during which their disease does not get worse after starting a treatment — half the patients went longer without progression and half progressed sooner. Investors use it as an early measure of a drug’s effectiveness and commercial promise, because longer progression-free times can signal stronger clinical benefit, higher chances of regulatory approval, and greater market value, even though it is not the same as overall survival.
right-of-use assets financial
"Right-of-use assets - operating leases"
Right-of-use assets are the rights a company gains to use a physical space or equipment under a lease agreement. They are recorded as assets on the company's balance sheet, reflecting the value of future benefits from the leased item. For investors, these assets provide a clearer picture of a company's obligations and resources related to leasing arrangements, helping to assess its financial health and operational commitments.

Advanced next-generation gamma delta (γδ) T cell engager (TCE) platform demonstrating a novel mechanism for γδ T cell expansion, deep target cell depletion, and favorable cytokine profile; Initial in vivo data expected in the second half of 2026
Presented updated data at ASCO 2026 demonstrating median overall survival (mOS) exceeding 19.5 months and still climbing, across all patients with newly diagnosed glioblastoma (GBM) treated with repeat-dosing of DeltEx™ Drug Resistant Immunotherapy (DRI)
Published peer-reviewed clinical data from Phase 1 INB-200 trial in The Journal of Clinical Oncology (JCO) demonstrating DeltEx™ DRI more than doubled expected median progression-free survival (mPFS) in newly diagnosed GBM
Reported new translational AI proteomic and immunogenomic analyses demonstrating DeltEx DRI preserves immune function and positively remodels the GBM tumor microenvironment, providing additional evidence supporting its therapeutic efficacy potential

NEW YORK, August 6, 2026 - IN8bio, Inc. (Nasdaq: INAB), a clinical-stage biopharmaceutical company developing innovative gamma-delta (γδ) T cell therapies and γδ T cell engagers (TCEs) for cancer and autoimmune diseases, today reported financial results and business highlights for the second quarter ended June 30, 2026.

“The second quarter marked an important period of scientific and clinical validation for γδ T cell therapeutics and IN8bio. Our γδ TCE platform is progressing, with INB-619 advancing into initial animal models. We are pleased to remain on track for reporting initial in vivo data this year,” said William Ho, Chief Executive Officer and co-founder of IN8bio. “In addition, peer-reviewed and updated clinical data from our glioblastoma program continue to demonstrate a favorable safety profile and provide strong evidence that γδ T cells are clinically active and can be delivered safely to potentially improve patient outcomes. We remain focused on disciplined execution, as we continue to seek a regulatory pathway for our glioblastoma program, with the ultimate goal of bringing much needed treatment to patients.”

Advancing Next-Generation γδ TCE Platform (INB-619)

Continued advancement of proprietary INB-600 platform of novel γδ T cell engagers, designed to selectively eliminate targets such as CD19, potentially reducing toxicities including cytokine release syndrome (CRS) and infections, while expanding the therapeutic window compared with conventional CD3-targeting T cell engagers.


 

Advancing INB-619, a CD19-targeting γδ T cell engager for oncology and autoimmune diseases, into IND-enabling studies following encouraging early preclinical data demonstrating complete B cell depletion, robust γδ T cell expansion, and minimal CRS-associated cytokine release, including IL-6 and TNF-α.
Remain on track to report initial in vivo preclinical data in the second half of 2026.

Reported Clinical and Translational Advances for DeltEx™ DRI in Newly Diagnosed Glioblastoma

During the second quarter, IN8bio reported multiple clinical and scientific milestones supporting the clinical activity of γδ T cells and IN8bio’s DeltEx™ DRI platform:

Published the first peer-reviewed clinical results of DeltEx DRI in newly diagnosed GBM in The Journal of Clinical Oncology. Among all patients treated, no dose-limiting toxicities (DLTs), CRS or immune effector cell-associated neurotoxicity syndrome (ICANS) were observed.
Presented updated clinical data at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting demonstrating encouraging survival benefit in repeat-dose treated patients, with mPFS of 13.0 months versus 6.6 months for contemporaneously enrolled patients receiving only standard-of-care (SOC) and mOS exceeding 19.5+ months versus 13.2 months for SOC.
Approximately 43% of repeat-dose patients remained alive at 24 months compared with 20% of SOC patients.
Presented new translational data at the International Society for Cell & Gene Therapy (ISCT) and International Society for Cell & Gene Therapy (ISCT) and American Society of Gene & Cell Therapy (ASGCT) Annual Meetings integrating artificial intelligence (AI), immunogenomics, histopathology, transcriptomics and spatial proteomics. Repeated DeltEx™ DRI dosing demonstrated preserved immune function during chemotherapy and positively remodeled the glioblastoma tumor microenvironment.
Spatial proteomics analyses demonstrated an 18-fold increase in intratumoral CD8+ T cell density and a 90% reduction in immunosuppressive granulocytes, providing mechanistic support for the clinical activity observed with DeltEx™ DRI.

 


 

IN8bio Chief Scientific Officer Lawrence Lamb co-authored a review in Nature Communications highlighting advances in γδ T cell engineering, γδ T cell engagers, CAR γδ T cells and combination immunotherapy strategies, reinforcing IN8bio's scientific leadership in the rapidly expanding γδ T cell field.
The publication highlights the potential of “off-the-shelf” γδ T cell therapies, driven by the cells’ lack of graft-versus-host disease (GvHD), and the growing clinical evidence supporting their application across hematologic malignancies and solid tumors, including GBM.

Upcoming Anticipated Milestones

Report initial preclinical animal data for INB-619 in the second half of 2026.
