Testing different radiation schedules for metastatic prostate cancer

A Randomized Phase III, Multicenter Study to Evaluate Different Fractionation Schedules of Radiotherapy to the Primary Tumour in Metastatic Hormone Sensitive Prostate Cancer

Not applicable Interventional Umeå University · NCT04612907

This study is testing whether a more intense radiation schedule works better and causes fewer side effects for people with newly diagnosed metastatic prostate cancer.

What this trial studies

This clinical trial investigates the effectiveness of two different radiation fractionation schedules for patients with de Novo metastatic prostate cancer that has limited spread. The standard schedule involves delivering 3 Gy of radiation over 19-20 sessions, while the trial will also evaluate a more intensive schedule of 6.1 Gy over 6 sessions. The goal is to compare the patient-reported side effects between these two approaches to determine which is more beneficial. Participants will be closely monitored for their responses to treatment and any adverse effects experienced.

Who should consider this trial

Good fit: Ideal candidates include men with histologically confirmed prostate cancer and low burden metastatic disease, as defined by specific criteria.

Not a fit: Patients with high burden metastatic prostate cancer or those with severe urinary problems may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved radiation treatment options that minimize side effects for patients with metastatic prostate cancer.

How similar studies have performed: Previous studies have shown promising results with hypo-fractionated radiotherapy approaches, suggesting potential for success in this trial.
