Official title: A Phase Ib/II Open-label, Multi-center Study of AMO959 With Lutetium (177Lu) Vipivotide Tetraxetan (AAA617) in Combination With an Androgen Receptor Pathway Inhibitor (ARPI) in Adult Participants With PSMA-positive Metastatic Castration Resistant Prostate Cancer (mCRPC) Summary: The purpose of this phase Ib/II study is to (a) in Phase Ib evaluate the safety, tolerability, and pharmacokinetics (PK) of AMO959 when given in combination with lutetium (177Lu) vipivotide tetraxetan (also known as [177Lu]Lu-PSMA-617 or 177Lu-PSMA-617 and hereafter referred to as AAA617) with an androgen receptor pathway inhibitor (ARPI) in participants with metastatic castration resistant prostate cancer (mCRPC) who have failed one prior ARPI and with or without prior taxane exposure, and (b) in Phase II evaluate the preliminary efficacy of AMO959 in combination with AAA617 and ARPI in participants with mCRPC who have failed one prior ARPI, but who have not yet been exposed to taxane treatment.
