Muscle loss in men with prostate cancer on hormone therapy

SArcopenia in Men with Prostate Cancer undergoing ADT (SAP-ADT)

NIH-funded research Seattle Inst for Biomedical/clinical Res · NIH-11258962

This project will follow men starting androgen deprivation (hormone) therapy for prostate cancer to track muscle loss, strength, and quality of life over 12 months.

What this research studies

If you join, you'll be one of about 70 men who start ADT and will be followed with regular visits for a year. Researchers will measure body composition with scans, test muscle strength and walking ability, collect blood samples and optional muscle biopsies, and ask about symptoms and daily function. They will study biological pathways including mitochondrial changes and search for clinical measurements that predict who loses muscle. The team will also collect patient-reported quality-of-life information to better understand the lived experience of muscle loss during treatment.

Who could benefit from this research

Good fit: Ideal candidates are men with a diagnosis of prostate cancer who are about to start or have recently started androgen deprivation therapy and can attend study visits for 12 months.

Not a fit: Men not receiving ADT, those with severe medical issues that prevent study procedures (such as muscle biopsy), or those unwilling to complete follow-up are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this work could help doctors predict who will lose muscle on ADT and guide future treatments to preserve strength and quality of life.

How similar studies have performed: Previous research has shown ADT commonly causes muscle loss but there are no approved drugs for sarcopenia and predicting who will develop it is still largely untested, so elements of this work are novel.
