Antineoplaston Therapy in Treating Patients With Neuroendocrine Tumor That Is Metastatic or Unlikely to Respond to Surgery or Radiation Therapy

• Status: Withdrawn
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Antineoplastons are naturally-occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells.

PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with neuroendocrine tumor that is metastatic or unlikely to respond to surgery or radiation therapy.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Burzynski Research Institute
