TuHURA Biosciences Receives FDA "Study May Proceed" Notice and IND Clearance for the Evaluation of its TBS-2025 VISTA-Inhibiting Antibody in Molecularly Defined Subsets of AML and Other Blood-Related Cancers
The FDA has issued a 'Study May Proceed' notice and cleared TuHURA Biosciences' IND application for TBS-2025, a VISTA-inhibiting antibody, for molecularly defined subsets of acute myeloid leukemia and other blood-related cancers.
The clearance enables a Phase 1b study of TBS-2025 monotherapy in relapsed/refractory mutNPM1 AML patients who failed menin inhibitor therapy — a population with no approved treatments. If dose-optimization response rates are encouraging, TuHURA will discuss trial expansion with the FDA toward a potential accelerated approval.
CEO Dr. James Bianco called it a major milestone, noting TuHURA is the only known company to advance a VISTA-inhibiting mAb through the IND process into a Phase 1b AML study; preclinical murine models showed TBS-2025 improved survival.
TBS-2025 is TuHURA's second clinical pipeline asset behind IFx-2.0, which is in a Phase 3 registration trial as an adjunct to Keytruda in first-line advanced or metastatic Merkel Cell Carcinoma.
