Low Dose Naltrexone (LDN) for Management of Fatigue in Prostate Cancer Patients on Androgen Deprivation Therapy (ADT)

Summary

The study is being done to see if a small daily dose of naltrexone (LDN, 3 mg pill) can help reduce tiredness (fatigue) in men with prostate cancer. All men in this study are being treated with hormone therapy (also called androgen deprivation therapy, or ADT). Some may also be taking newer hormone medicines such as apalutamide, daralutamide, enzalutamide, or abiraterone.

* Initiation of hormonal ablative therapy within 3 months of registration.
* ECOG performance status \<3.
* Patients must have normal organ and marrow function as defined below:

  * leukocytes \>3,000/μL
  * absolute neutrophil count \>1,500/μL
