Bayer has announced the commencement of dosing in a Phase I clinical study for 225Ac-PSMA-Trillium (BAY 3563254), a novel targeted alpha therapy aimed at treating advanced metastatic castration-resistant prostate cancer (mCRPC). This investigational candidate, utilizing actinium-225, features a unique PSMA-targeting small molecule with a customized albumin-binding component. The study, identified as NCT06217822, will focus on assessing the safety, tolerability, and efficacy of 225Ac-PSMA-Trillium.
Fred Saad, MD, FRCS, Professor and Chairman of Surgery at the University of Montreal, expressed the high unmet need for precision therapy options in mCRPC. He highlighted the potential of 225Ac-PSMA-Trillium to address this need effectively. Bayer’s Dominik Ruettinger, M.D., Ph.D., emphasized the strategic importance of targeted radionuclide therapy in precision oncology, especially for patients with treatment-resistant disease. The company aims to leverage the unique design of 225Ac-PSMA-Trillium to provide significant benefits for patients with metastatic prostate cancer.
Despite significant advancements in prostate cancer treatment, mCRPC remains a major challenge, with Bayer reaffirming its commitment to innovation across all stages of the disease. The introduction of 225Ac-PSMA-Trillium at the AACR Annual Meeting and the subsequent Phase 0 clinical imaging and dosimetry study underscore Bayer’s dedication to advancing medical solutions for prostate cancer patients.
Targeted alpha therapy represents a promising approach in oncology, delivering alpha particle radiation directly to tumors while potentially minimizing damage to surrounding healthy tissues. Bayer, as a global leader in life sciences, aims to drive sustainable development and positive impact through its innovative products and services. In fiscal 2023, the company’s focus on R&D and commitment to quality and reliability remained steadfast, reflecting its mission to improve health and well-being worldwide.
