Can epigenetic drugs prime prostate tumors for immune attack before surgery?
NCT ID NCT06888102
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This early-phase trial is testing whether giving epigenetic therapy before prostate removal can make the cancer more visible to the immune system. About 20 men with high-risk prostate cancer will receive the drugs before their scheduled prostatectomy. The main goals are to check safety, see if the treatment delays surgery, and measure changes in gene activity in the removed tissue.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- epigenetic therapy (drugs that change gene activity to help the immune system attack cancer)
- What this could lead to
- If it works, this could point toward a new way to make prostate cancer more sensitive to the immune system before surgery.
- What could go wrong
- This is a very early, small trial (20 men) focused on safety and feasibility, not effectiveness. The drugs may cause side effects or not improve outcomes.

Inclusion Criteria * Men electing to undergo radical prostatectomy with preoperative tissue available. * Age ≥18 years * Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 * Adequate organ function defined by: * AST and ALT \< 2.5 x ULN * Total bilirubin \< 1.5 x ULN * Platelets \> 90 x 1000/μL * Hemoglobin (Hgb) \> 8.5 g/dL * Serum Creatinine (Cr) \<1.5 x ULN or eGFR \> 30 mL/min * People with partners of childbearing potential in circumstances that may result in the pregnancy, must have had a successful vasectomy (with medically confirmed lack of sperm that are alive) OR must either practice complete abstinence or agree to use adequate contraception (latex or synthetic condom during sexual contact with a female of childbearing potential) from the start of study treatment until 3 months following last dose of study intervention. Subjects should not donate sperm on study, during interruptions in treatment and for 3 months following completion of study drug treatment. * Written informed consent obtained from subject and ability for subject to comply with the requirements of the study. Exclusion Criteria * Active intercurrent illness or malignancy requiring therapy outside of prostate cancer. * Other anti-cancer therapy (chemotherapy, hormonal therapy, radiation therapy, surgery, immunotherapy, biologic therapy, or tumor embolization) * Currently participating in a study using an investigational, medicinal anti-cancer agent within 4 weeks prior to first dose of epigenetic therapy.
