Cash, cash equivalents and marketable securities were $538.5M as of March 31, compared to $226.8M as of December 31, 2025. "We continue to build momentum toward delivering a new class of radiopharmaceuticals targeting tumor types with large patient populations, leveraging our differentiated miniprotein radioconjugate platform and patient-first end-to-end supply chain," said Matthew Roden, President and Chief Executive Officer of Aktis Oncology. "Last week, we announced the initiation of our Phase 1b clinical trial of AKY-2519 in patients with mCRPC. This is the first of two trials in our clinical development strategy designed to expand the breadth of tumors studied and augment speed to data, with preliminary data from the mCRPC trial anticipated in 2027. We plan to initiate a second Phase 1b basket trial of AKY-2519 in additional solid tumors in the second half of this year. We also look forward to presenting our first AKY-2519 clinical imaging and dosimetry data for AKY-2519 at ASCO, which informed our clinical development strategy."
