Prostatic Neoplasm Clinical Trial
Official title:
A Phase II Trial of Leuprolide + Flutamide + Suramin in Untreated Poor Prognosis Prostate Carcinoma
One current hypothesis as to what limits duration of initial hormone response is the rapid emergence of hormone resistant prostate carcinoma cells. Suramin has shown effectiveness as a treatment for hormonally refractory prostate carcinoma. Survival was less in patients with high rather than low circulating androgen levels. Thus, suramin might slow the emergence of hormone refractory tumor cells while combined androgen ablation may maximize the effectiveness of suramin. In this trial, we will pilot this concept.

INCLUSION CRITERIA: Patients must have a histologic diagnosis of carcinoma of the prostate and must not have had a trial of hormonal therapy or chemotherapy. Patients must be 18 years of age and an SGOT/SGPT within 2 times of normal. Patients must have stage D2 prostate carcinoma or State D1 disease with a Gleason grade 7 or above (poorly differentiated). No other malignancy except curatively treated basal cell cancer of the skin. Performance status ECOG of 0-3. Ability to give informed consent. No history of bleeding diathesis. Patients with a history of peptic ulcer disease will be eligible if the ulcer is shown to be resolved by a barium study. No history of cerebrovascular event, either thrombotic or hemorrhagic. No current clinical signs of congestive heart failure, angina pectoris or myocardial infarction. Patient cannot be on calcium channel blockers such as Nifedipine, Diltiazem, or Verapamil. No clinical or radiographic evidence of brain metastases. Patients with extensive liver replacement (greater than 50%) by tumor will be ineligible. Patients must have a creatinine lest than or equal 2.5 mg/dl or creatinine clearance of greater than or equal to 40 ml/min. Patients must have adequate hepatic function (bilirubin less than 1.5mg%). If the patient has white cells in his urinalysis or other evidence of a urinary tract infection, this must be evaluated and appropriate therapy initiation prior to the initiation of therapy. Patients must not have received chemotherapy. An absolute granulocyte count greater than 1,500; platelet count greater than 100,000; Fibrinogen greater than 200 mg/dl; Hgb greater than or equal to 9 gm/dl. Reliability of the patient to take oral medication, go home and return for follow-up and treatment. |
