NCT06888102 | RECRUITING | High-risk Prostate Cancer

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

Edwin Posadas, MD

Information provided by (Responsible Party):

Edwin Posadas, MD

Brief Summary:

This is an open-label, non-randomized, exploratory platform protocol designed to assess the safety and antitumor activity of epigenetic therapies in participants with localized prostate cancer who are undergoing radical prostatectomy. The epigenetic therapy is intended to increase the sensitivity of the underlying tumor to the patient's immune system. The platform study will evaluate safety, biomarkers, and clinical activity of an epigenetic therapy. The particular details relevant to each module within this platform study will be provided as appendices to the core protocol.

Condition or disease

High-risk Prostate Cancer

Intervention/treatment

Neoadjuvant Epigenetic Therapy

Phase

EARLY_PHASE1

Detailed Description:

The study lead investigators will modify and/or add new therapies to the protocol as data emerge from this and other trials. Participants must provide consent for archival biopsy tissue prior to surgery for prostate cancer and must consent to allowing for use of their surgical specimens from biopsy and prostatectomy for biomarker characterization. Given the absence of data in this setting, this pilot proposes this experience with up to 4 weeks of epigenetic agents at doses known to be clinically safe and effective at inducing clinical activity. 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.
