TuHURA Biosciences Announces Three Presentations at the 68th American Society of Hematology Annual Meeting and Exposition
TuHURA Biosciences (NASDAQ:HURA) will present three research posters at the American Society of Hematology annual meeting on December 14, 2026.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
TuHURA Biosciences (NASDAQ:HURA) will present three research posters at the American Society of Hematology annual meeting on December 14, 2026.
The meeting runs December 12–15 in New Orleans. The posters examine delta opioid receptor (DOR) inhibition in cells that suppress immune responses. Topics include changes in genes involved in cell growth, movement and immune suppression, and effects on proenkephalin gene expression and met-enkephalin protein. All three presentations are scheduled for 6:00–8:00 p.m. ET in MCCNO Hall F.

Presentations highlight the role of the Delta Opioid Receptor (DOR) as a novel target central to the regulation of multiple genes involved in immune suppression, chemotaxis and proliferation of immune suppressing cells in cancer and autoimmune disease including MDSCs, T regs, and M2 macrophages
"We continue to be impressed by uncovering the central role the DOR plays in proliferation, recruitment and immune suppressing capabilities across MDSCs, T regs and M2 macrophages, the 3 most important naturally occurring immune suppressing cells in the body. These immune suppressing cells are an important mechanism for the body to calm chronic inflammation, but when highjacked in the setting of cancer, they are known to be culprits in resistance to and failure of cancer immunotherapy," said Dr. James Bianco, President and Chief Executive Officer of TuHURA Biosciences. "In addition to providing information critical to multiple patent submissions, the data underscore the breadth of the potential therapeutic applications for DOR technology in the development of a first new class of non-tumor targeting, immune modulating ADCs."
Poster Presentation Details:

Session: 201. Granulocytes, Monocytes, and Macrophages: Poster III
Date and Time: Monday, December 14, 2026, 6:00pm to 8:00pm ET
Location: MCCNO – Hall F
Abstract Number: 4721
Title: Delta opioid receptor (DOR) inhibition drives both proenkephalin (PENK) gene expression and met-enkephalin (mENK) protein in tumor-derived myeloid-derived suppressor cells (tMDSC) and bone marrow-derived macrophage subtype 2 (BMDM2): Implications for modulation of immune suppression in cancer and autoimmune disease.

About TuHURA Biosciences, Inc.
TuHURA Biosciences, Inc. (NASDAQ: HURA) is a Phase 3 immuno-oncology company developing novel technologies to overcome primary and acquired resistance to cancer immunotherapy, two of the most common reasons cancer immunotherapies fail to work or stop working in the majority of patients with cancer.
TuHURA's lead innate immune agonist, IFx-2.0, is designed to overcome primary resistance to checkpoint inhibitors. TuHURA has initiated a single randomized placebo-controlled Phase 3 registration trial of IFx-2.0 administered as an adjunctive therapy to Keytruda® (pembrolizumab) compared to Keytruda® plus placebo in first-line treatment for advanced or metastatic Merkel Cell Carcinoma.
In addition to its innate immune agonist product candidates, TuHURA is developing TBS-2025, its VISTA-inhibiting mAb in a Phase 1b clinical trial in patients with mutNPM1 r/r AML, a molecularly defined subgroup that represents approximately
