ROADSTER Trial Summary

This trial will test whether adding 177-Lutetium-PSMA to standard salvage brachytherapy improves disease control in men with recurrent prostate cancer.

Who is the study for?
Men with prostate cancer recurrence after prior radiotherapy, confirmed by biopsy. They must have adequate liver and kidney function, no severe toxicity from previous treatments, and meet specific blood count criteria. The trial excludes those who've had certain types of prostate radiotherapy before or show signs of cancer spread beyond the prostate.Check my eligibility
What is being tested?
The study is testing a combination treatment for recurrent prostate cancer: high dose radiation (brachytherapy) alongside a radioactive drug called 177Lu-PSMA that targets cancer cells in the prostate and potentially elsewhere in the body.See study design
What are the potential side effects?
Possible side effects include reactions to radiation like skin changes or fatigue, as well as effects from the radioactive drug such as nausea, dry mouth, kidney issues, or blood cell changes.

Experimental Treatment
Active Control
Group I: Lutetium ArmExperimental Treatment2 Interventions
Patients in Lutetium Arm will receive 1 cycle of 177Lu-PSMA radioligand therapy plus 1 fraction of HDR brachytherapy.
Group II: High Dose Radiation (HDR) armActive Control1 Intervention
Patients in the HDR arm will receive two fractions of HDR brachytherapy. HDR brachytherapy will be administered as per local practice and as previously described. All procedures will be conducted under general anesthesia in a dedicated brachytherapy suite using transrectal three dimensional ultrasound for image guidance. For all HDR fractions at least 10Gy will be delivered to the entire prostate with a boost to 13.5Gy to the involved prostate as determined by biopsy and PSMA PET/MRI results. In instances of multi-focal/diffuse involvement of the prostate, the entire prostate will receive 13.5Gy/fraction (respecting OAR constraints).
