TuHURA Biosciences reported initial data from the first three patients in its open-label Phase 1b/2a study of IFx-2.0 plus Keytruda in first-line metastatic Merkel Cell Carcinoma. All three patients achieved partial responses per RECIST v1.1, with every response ongoing at the protocol-specified six-month assessment, and CT/ultrasound-guided administration was shown to be safe and feasible in deep-seated bulky tumors.
