Overview
Multicenter Phase 3 study of 177Lu-TLX250 in adult participants with CAIX-expressing advanced, relapsed or recurrent clear cell renal cell carcinoma (ccRCC). Part 1 will evaluate two dosing regimens to determine the recommended Phase 3 dose (RP3D). Part 2 will compare 177Lu-TLX250 with investigator's choice of monotherapy aligned with Australian standard-of-care.
Description
This is a randomized, open-label, multi-center 3 study evaluating the safety and efficacy of 177Lu-TLX250, a CAIX-targeting radioligand therapy, in adult participants with advanced, relapsed or recurrent clear cell renal cell carcinoma (ccRCC).
The study consists of two parts:
• Part 1 (Phase 2a - Dose Optimization): Participants will be randomized to receive one of two dosing regimens of 177Lu-TLX250.
The objective of Part 1 is to determine the recommended Phase 3 dose (RP3D) for use in Part 2.
