Antineoplaston Therapy in Treating Patients With Refractory Stage IV Prostate Cancer

Phase II Study of Antineoplaston A10 and AS2-1 in Patients With Adenocarcinoma of the Prostate

Current therapies for Refractory Stage IV Prostate Cancer provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Refractory Stage IV Prostate Cancer.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Refractory Stage IV Prostate Cancer.

Study Overview

• Status: Withdrawn
• Conditions: Stage IV Prostate Cancer
• Intervention / Treatment: Drug: Antineoplaston therapy (Atengenal + Astugenal)

Detailed Description

Refractory Stage IV Prostate Cancer patients receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues up to 12 months in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:

• To determine the efficacy of Antineoplaston therapy in patients with Refractory Stage IV Prostate Cancer, as measured by an objective response to therapy (complete response, partial response or stable disease).
• To determine the safety and tolerance of Antineoplaston therapy in patients with Refractory Stage IV Prostate Cancer.
• To determine objective response, tumor size is measured utilizing MRI scans, which are performed every 8 weeks for the first two years, every 3 months for the third and fourth years, every 6 months for the 5th and sixth years, and annually thereafter.

• Study Type: Interventional
• Phase: Phase 2

Participant Group / Arm

Intervention / Treatment

Experimental: Antineoplaston therapy; Antineoplaston therapy (Atengenal + Astugenal) by IV infusion every four hours for at least 12 months. Study subjects receive increasing dosages of Atengenal and Astugenal until the maximum tolerated dose is reached.

Drug: Antineoplaston therapy (Atengenal + Astugenal); Patients With Refractory Stage IV Prostate Cancer will receive Antineoplaston therapy (Atengenal + Astugenal). The daily doses of A10 and AS2-1 are divided into six infusions, which are given at 4-hourly intervals. Each infusion starts with infusion of A10 and is immediately followed by infusion of AS2-1.; Other Names: A10 (Atengenal); AS2-1 (Astugenal)ANP
