(NASDAQ:AKTS) (Aktis or the Company), a clinical-stage oncology company focused on expanding the breakthrough potential of targeted radiopharmaceuticals to large populations, including those not addressed by existing platform technologies, today reported first-in-human clinical imaging and dosimetry data for AKY-2519, a miniprotein radioconjugate targeting B7-H3 expressing tumors. The data from two separate assessments of AKY-2519 – a clinical imaging and dosimetry assessment in patients with mCRPC and a clinical imaging assessment in patients with various solid tumor types – demonstrated robust tumor uptake and limited normal tissue exposure. These findings, which supported the advancement of a broad clinical development program for AKY-2519, will be presented in two poster presentations at the upcoming 2026 ASCO Annual Meeting, being held May 29 – June 2, 2026, in Chicago.
