Description:

Phase 1: The objective of the Phase 1 part of the clinical trial is to verify safety and tolerability (dose-limiting toxicity [DLT], maximum tolerated dose [MTD]) of a single 3.7 Giga-Becquerel (GBq) dose with the potential for one dose level de-escalation to 2.775 GBq if necessary, to determine the recommended [177Lu]Ludotadipep dose for use in the Phase 2a part of the trial. Phase 2a: The objective of the Phase 2a part of the trial is to evaluate safety and efficacy for repeated administration of the recommended [177Lu]Ludotadipep dose. The Recommended Phase 2 dose (RP2D) will be based on the study results from the Phase 1 trial in South Korea upon consultation with the FDA.
