ARAMON Trial Summary

This trial aims to find a better way to treat prostate cancer that has returned after local treatment, with fewer side effects than existing treatments.

Who is the study for?
Men over 18 with hormone-naïve prostate cancer that's come back after surgery or radiation, shown by rising PSA levels without visible spreading. They must have good organ function and no more than five non-painful metastatic lesions. No recent major surgeries or certain past treatments like ADT in the last six months are allowed.Check my eligibility
What is being tested?
The ARAMON study is testing how Darolutamide affects testosterone levels compared to Enzalutamide in men with recurring prostate cancer not treated hormonally before. Initially, all take Darolutamide; based on results, they may later be randomly assigned to continue it or switch to Enzalutamide.See study design
What are the potential side effects?
Possible side effects include feminizing effects such as breast growth and tenderness due to increased testosterone from Enzalutamide. Darolutamide might cause fewer CNS-related side effects because of its structure limiting brain entry.
