• * Agree to comply with all study procedures and attend all study visits.
• * Male aged \>=40 years.
• * History of prostate cancer diagnosis: Subjects with treated prostate cancer are eligible. Prior prostate cancer treatments must be clearly defined. Acceptable treatment modalities include surgery, radiation therapy, and previous use of antiandrogen therapy. Subjects with localized prostate cancer in low-risk group who were not on treatment or declined any treatment are eligible. Subjects with localized prostate cancer in the favorable intermediate-risk group who declined any treatment are eligible.
• * Subjects must not be undergoing concurrent radiation therapy or androgen deprivation therapy (ADT) at the time of enrollment.
• * ECOG performance status 0-2.
• * Subjects must have normal liver and kidney function at baseline: Total bilirubin within normal institutional limits. AST(SGOT)/ALT(SGPT) \< 2.5 X upper limit of normal (ULN). Creatinine \< 1.5 ULN or creatinine clearance \> 50 mL/min/1.73 m2. Adequate bone marrow function: Hgb ≥ 9.0 g/dL, Platelets ≥ 100 x 109/L, absolute neutrophil count of ≥ 1.0 x 109/L).
• * Subjects and their partners must agree to use two medically accepted methods of contraception and must agree to continue use these methods during the trial and for at least one week after the last dose of study drug. Acceptable methods of contraception include abstinence, barrier method with spermicide, intrauterine device (IUD) known to have a failure rate of less than 1% per year, or steroidal contraceptive (oral, transdermal, implanted, or injected) in conjunction with a barrier method. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods) withdrawal, spermicides only, or lactational amenorrhea are not acceptable methods of contraception.
• * Subjects taking strong inhibitors or inducers of CYP3A4 or CYP2C19 must be evaluated for potential drug interactions with the study drug. Essential medications, such as statins, that cannot be discontinued may be allowed at the investigator's discretion.
• * Subjects currently taking herbal supplements containing AGN extract, such as Cogni.Q, Decursinol-50, Ache Action, Fast-Acting Joint Formula, must discontinue these or any other supplements containing these products at least 4 weeks prior to starting study drug.
• * Willingness and ability to give informed consent.

• * Histologically confirmed adenocarcinoma of prostate (neuroendocrine or small cell prostate cancer excluded).
• * Any T stage, N0-1, M0, any Gleason grade.
• * Subjects must meet one of the following: Post-radical prostatectomy (RP) and/or post-radiation therapy (RT), including those with local recurrence declining further treatment. Localized prostate cancer who declined any treatment after physician discussion.
• * No distant metastases disease confirmed by imaging (CT or MRI and bone scan or prostate-specific PET scan such as PSMA PET scan or Axumin PET scan) within 5 years prior to enrollment.
• * Blood PSA level rising over 2 consecutive tests within the past 6 months, at least one week apart.
• * Not currently receiving concurrent androgen deprivation therapy, and testosterone levels should be within a non-castrate range (\>50 ng/dL).
• * ECOG performance status 0-2.
• * Subjects must have normal liver, kidney, and bone marrow function at baseline: Total bilirubin within institutional limits. AST(SGOT)/ALT(SGPT) \< 2.5 X upper limit of normal (ULN). Creatinine \< 1.5 ULN or creatinine clearance \> 50 mL/min/1.73 m2. Adequate bone marrow function: Hgb ≥ 9.0 g/dL, Platelets ≥ 100 x 109/L, absolute neutrophil count ≥ 1.0 x 109/L.
• * No evidence of any active secondary malignancy requiring ongoing treatment.
• * Subjects must agree to use two medically accepted method of contraception and must agree to continue use this method while on the trial and through at least one week after the last dose of study drug. Acceptable methods of contraception include abstinence, barrier method with spermicide, intrauterine device (IUD) known to have a failure rate of less than 1% per year, or steroidal contraceptive (oral, transdermal, implanted, or injected) in conjunction with a barrier method. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods) withdrawal, spermicides only, or lactational amenorrhea are not acceptable methods of contraception.
• * Subjects taking strong inhibitors or inducers of CYP3A4 or CYP2C19 will be evaluated for potential drug interactions with the study drug. Essential medications, such as statins, that cannot be discontinued may be allowed at the investigator's discretion.
• * Subjects currently taking herbal supplements containing AGN extract, including Cogni.Q, Decursinol-50, Ache Action, Fast-Acting Joint Formula, must discontinue these or any other supplements containing these products at least 4 weeks prior to starting study drug.
• * Subjects with distant metastatic cancer. Node-positive prostate cancer patients are allowed after completion of treatment.
• * Subjects who are receiving systemic treatments such as chemotherapy, androgen deprivation therapy (ADT) or anti-androgen therapy including LHRH agonist, antagonist, GNRH analogs, and antiandrogens, or immunotherapy (checkpoint inhibitor) or investigational agents.
• * Participants will be excluded if they have any uncontrolled intercurrent illness at the discretion of the treating investigator. This may include, but is not limited to, the following conditions: ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, uncontrolled diabetes mellitus (DM) with an HbA1C \>9, uncontrolled asthma, or significant psychiatric illness that would limit compliance with study requirements.
• * History of New York Heart Association Class III or IV heart failure, history of a myocardial infarction within 6 months, or any other cardiac-related problem that would be considered a contraindication for participation in the opinion of the treating physician.
• * Any active secondary malignancy requiring treatment.
• * Chronic kidney disease with calculated GFR \<30 mL/min/1.73 m(2) using Cockcroft-Gault formula, or measured GFR \<30 mL/min/1.73 m(2) using a 24-hour urine collection. The hospital's lab measured GFR can be used if a 24-hour collection is not possible.
• * Subjects who are taking Warfarin/coumadin.
