Official title
Understanding the Interaction Between Androgen Receptor Signaling and Prostate-Specific Membrane Antigen Expression
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this research study is to determine whether hormonal therapies used early in the course of prostate cancer could increase the amount of Prostate-Specific Membrane Antigen (PSMA) as detected by PET/CT scans for participants with recurrent prostate cancer. This study will measure PSMA levels using standard PET/CT scans and participants will receive standard-of-care androgen receptor antagonist monotherapy. The names of the treatment interventions involved in this study are: * Androgen receptor antagonist monotherapy. * PSMA PET/CT scan It is expected that about 15 people will take part in this research study. Participation in this research study is expected to last about 4 weeks.
