Remotely Monitored Exercise Interventions in Patients With mCSPC Undergoing ADT (Prostate 006)

This study is testing whether a remotely monitored exercise program can help men with metastatic prostate cancer who are on hormone therapy (ADT) maintain their strength, physical function, and quality of life. Hormone therapy often causes muscle loss, fatigue, and metabolic changes that exercise may help counter. **You may be eligible if...** - You are a man aged 18 or older - You have been diagnosed with metastatic prostate cancer (cancer that has spread beyond the prostate) - You are starting or continuing hormone therapy (ADT/LHRH therapy) for your prostate cancer - You have not yet progressed to castrate-resistant disease **You may NOT be eligible if...** - Your prostate cancer is castrate-resistant (meaning it continues to grow despite hormone therapy that has reduced testosterone to very low levels) - Your prostate cancer has an elevated PSA after prior treatment but imaging shows no metastases (biochemical recurrence without spread) - You have bone metastases that make exercise unsafe - You have other serious conditions that would prevent safe participation in exercise Talk to your doctor to see if this trial is right for you.
