Combining α and β Radiopharmaceuticals in mCRPC: Interim AlphaBet Results Show Feasible Safety and Promising PSA Activity for 177Lu‑PSMA‑I&T plus 223Ra

Combining α and β Radiopharmaceuticals in mCRPC: Interim AlphaBet Results Show Feasible Safety and Promising PSA Activity for 177Lu‑PSMA‑I&T plus 223Ra

Interim data from the AlphaBet phase 1/2 trial show that combined 177Lu‑PSMA‑I&T and radium‑223 is feasible, with no dose‑limiting toxicities, a recommended radium‑223 dose of 55.0 kBq/kg, and a PSA50 rate of 55% (95% CI 36–72). Hematologic grade ≥3 adverse events were uncommon.
