Study Arms (1)

Metformin + OPC dose escalation

EXPERIMENTAL
Drug: MetforminDrug: Oligomeric Procyanidin Complex

Interventions

Metformin: The starting dose for Metformin is 850mg once a day, the second dose is 850mg once a day; the third dose level is 850mg twice a day; the fourth dose level is 850mg twice a day. Each dose level lasts for 28 days.

Metformin + OPC dose escalation

OPC: The starting dose for OPC is 500mg once a day; the second dose is 1000mg once a day; the third dose level is 1000mg once a day; the fourth dose level is 1500mg once a day. Each dose level lasts for 28 days.

Also known as: OPC
Metformin + OPC dose escalation

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Confirmation of adenocarcinoma of the prostate that is documented by one of the following: pathology report or clinic note with documented history of prostate cancer.
  • Subjects must be receiving ADT with a GnRH agonist or antagonist, with or without an anti-androgen, with a current testosterone level documented to be \<50ng/dL at enrollment. Subjects whose ADT is interrupted may enroll or continue on study as long as the testosterone is documented to remain \<50ng/dL for the entire duration of study participation. Subjects who have undergone orchiectomy are also eligible.
  • Subjects must have adequate hematologic, renal, and hepatic function at baseline, as follows:
  • Hematology parameters: ANC \>1000/mcL, platelets \> 100,000/mcL, Hgb \>8.0gm/dL
  • Renal Function: eGFR of ≥ 45mls/min using Cockkroft and Gault formula (see appendix C).
  • Liver Function: Total bilirubin ≤ULN, AST and ALT \<1.5xULN, Prior radiation therapy allowed
  • Subjects may have diabetes mellitus but must not be taking metformin.
  • Able to swallow and retain oral medication
  • ECOG performance status of 0 - 2
  • Ability to sign written informed consent
  • Testosterone level \<50ng/dL at time of enrollment.
  • Age 18 or older.

You may not qualify if:

  • Known allergy to grapes or grape seed
  • Known hypersensitivity or intolerance to metformin.
  • Any condition associated with increased risk of metformin-associated lactic acidosis (e.g. congestive heart failure defined as NYHA Class III or IV functional status, history of acidosis of any type; habitual intake of 3 or more alcoholic beverages per day).
  • Prior cytotoxic chemotherapy for metastatic prostate cancer; prior treatment with genomically-targeted agents, or Provenge is allowed.
  • History of receiving more than 2 classes of ADT.
  • Current use of metformin, or strong antioxidants (extracts from grape seed, milk thistle; pine bark, green tea, saw palmetto; resveratrol; flavonoids; catechins; ellagic acid), large quantities of red grapes, white button mushrooms, red wine
  • PSA doubling time of \<6 months, measured over the 3 months prior to enrollment.
