A Platform Study of Epigenetic Therapy Before Prostatectomy in Men With Prostate Cancer

Participants will be assigned to receive one of the study interventions and will be monitored for safety and response. The duration of epigenetic therapy will be dependent on the treatment administered and will continue for the duration described in the cohort appendix for each respective combination, unless the participant: is no longer clinically benefiting (NLCB, as evidenced by symptomatic or radiographic disease progression and/or clinical deterioration); experiences any toxicity meeting specified discontinuation criteria (as described in the cohort appendix for each respective combination) or unacceptable toxicity in the best clinical discretion of the treating physician (i.e., Investigator discretion); reaches the maximum duration of study intervention; or withdraws consent.
