Open-label Study Comparing AAA817 Versus Standard of Care in the Treatment of Previously Treated PSMA-positive mCRPC Adults Who Have Disease Progressed on or After [177Lu]Lu-PSMA Targeted Therapy

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


Sponsor

Novartis Pharmaceuticals

Enrollment

443 participants

Start Date

Feb 27, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

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


Eligibility

Sex: MALEMin Age: 18 YearsMax Age: 100 Years

Plain Language Summary

Simplified for easier understanding

This study is testing a new radioactive drug called AAA817 in men with advanced prostate cancer that has spread (metastatic castration-resistant prostate cancer, or mCRPC) and has already been treated with lutetium-177 PSMA therapy (a type of radiation therapy targeting the PSMA protein on cancer cells). Researchers want to see if AAA817 is more effective than standard treatments in this setting. **You may be eligible if...** - You are a man, 18 years of age or older - You have confirmed prostate cancer with spread (adenocarcinoma of the prostate) - Your prostate cancer cells test positive for the PSMA protein on a PET/CT scan - Your testosterone level is at castrate levels (very low) - You have already received androgen receptor pathway therapy, taxane-based chemotherapy, and lutetium-177 PSMA therapy, and your cancer has progressed - You have at least one measurable lesion on imaging **You may NOT be eligible if...** - Your cancer does not express PSMA on scans - You have not received the required prior treatments - You have serious kidney, blood, or organ function problems Talk to your doctor to see if this trial is right for you.
