PSMAcTION: A Phase II/III, Open-label, International, Multicenter, Randomized Study of AAA817 Versus Standard of Care in the Treatment of Adult Participants With PSMA Positive Metastatic Castration-resistant Prostate Cancer Who Progressed on or After [177Lu]Lu-PSMA Targeted Therapy

This is a Phase II/III study. Patient population is adult participants with PSMA-positive mCRPC who had treatments with androgen receptor pathway inhibitor (ARPI) and taxane-based chemotherapy and progressed on or after [177Lu]Lu-PSMA targeted therapy.

Treatment of interest: the investigational treatment is AAA817 regardless of subsequent anti-neoplastic treatment. The control treatment is investigator's choice of Standard of Care, regardless of subsequent anti-neoplastic treatment

Inclusion: adults ≥ 18 years of age; ECOG performance status of 0 to 2; histopathological and/or cytological confirmation of adenocarcinoma of the prostate; PSMA-positive disease as assessed by PSMA PET/CT scan using an approved PSMA imaging agent as protocol instructed,; castrate level of serum/plasma testosterone (< 50 ng/dL or < 1.7 nmol/L); Prior treatments with an androgen receptor pathway inhibitor (ARPI) and taxane-based chemotherapy, and progressed on or after [177Lu]Lu-PSMA targeted therapy; ≥ 1 metastatic lesion that is present on screening/baseline CT, MRI, or bone scan imaging obtained ≤ 28 days prior to randomization; eGFR as requested by the sponsor.

Exclusion: Any investigational agents within 28 days prior to the day of randomization; Any 225Ac-based investigational compound used prior to the day of randomization; Participants with a history of CNS metastases who are neurologically unstable, symptomatic, or receiving corticosteroids for the purpose of maintaining neurologic integrity; Concurrent acute kidney injury (renal failure developed between 48 hours to 7 days) or chronic kidney disease (at least 3 months of ongoing renal injury); History of uncontrolled hypertension, myocardial infarction (MI), angina pectoris, or coronary artery bypass graft (CABG) within 6 months prior to ICF signature and/or clinically active significant cardiac disease; History of lymphoproliferative disease or any known malignancy or history of malignancy of any organ system within the past 2 years (except for basal cell carcinoma or actinic keratosis that have been treated with no evidence of recurrence in the past 3 months, non-invasive malignant colon polyps that have been removed); Other protocol-defined inclusion/exclusion criteria may apply; Baseline xerostomia ≥ Grade 2 by CTCAE v.5.
