Is NCT06235697 recruiting? Yes, currently enrolling (May 2026). This Phase 3 trial studies ADT for prostate cancer.

Phase 3RecruitingCanadian Cancer Trials GroupNCT06235697Data as of May 2026

Treatment: ADTThis study is being done to answer the following question: Is the strategy to give higher doses of radiotherapy treatment over a shorter period of time using special equipment and fewer treatments (also known as Stereotactic Body Radiation Therapy or SBRT) as effective as usual external radiation therapy given with a brachytherapy boost (which involves radiation sources inserted directly into the prostate)?
