TAMPA, Fla., May 5, 2025 /PRNewswire/ -- TuHURA Biosciences, Inc. (NASDAQ:HURA) ("TuHURA" or the "Company"), a Phase 3 immune-oncology company developing novel technologies to overcome resistance to cancer immunotherapy, today announced the initiation of its Phase 1b/2a trial of IFx-Hu2.0, TuHURA's lead innate immune agonist, in patients with MCCUP who would not be eligible for the Company's planned Phase 3 accelerated approval trial, which is targeted to begin enrollment later in Q2 2025.  IFx-Hu2.0 is designed to overcome primary resistance to checkpoint inhibitors (CPIs) like Keytruda® and has demonstrated systemic anti-tumor specific immune responses (abscopal effect) when injected intratumorally into cutaneous, subcutaneous, or accessible nodal lesions in its prior Phase 1 and 1b trials in melanoma and advanced or metastatic Merkel cell carcinoma (MCC).
