This is an open-label, randomized, multicenter study of FPI-2265 (225Ac-PSMA-I\&T). Patient population is adult participants with PSMA positive mCRPC who have had previous treatment with with 177Lu-PSMA-617 or another 177Lu-PSMA radioconjugate (RC). The purpose of the study is to determine the safety and tolerability, and recommended dose and regiment of FPI-2265.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Fusion Pharmaceuticals (FUSN) is the sponsoring company for this trial. BiotechSign currently grades this company D (40/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
