What this trial studies

This is a single-center, prospective study focusing on patients with metastatic castration-resistant prostate cancer (mCRPC) who are scheduled to receive Lutetium labelled prostate-specific membrane antigen radioligand therapy (LuPSMA RLT). Participants will undergo baseline imaging with 18F-Fluciclovine PET/CT and will have follow-up scans after the 2nd, 4th, and 6th cycles of LuPSMA RLT. The study aims to analyze the imaging data to correlate PET metrics with clinical outcomes, providing insights into the effectiveness of the therapy. The goal is to assess how well these imaging techniques can predict patient responses to treatment.

Who should consider this trial

Good fit: Ideal candidates for this study are adult males diagnosed with metastatic castration-resistant prostate cancer who are scheduled to receive LuPSMA RLT.

Not a fit: Patients under 18 years old or those with serious concurrent illnesses that may interfere with study procedures will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the ability to predict clinical outcomes for patients undergoing prostate cancer therapy, leading to more personalized treatment plans.

How similar studies have performed: Other studies have shown promise in using PET imaging to assess treatment responses in prostate cancer, suggesting that this approach may yield valuable insights.
