Antineoplaston Therapy in Treating Patients With Cancer of Unknown Primary Origin
This trial is active, not recruiting.
|Condition||carcinoma of unknown primary|
|Treatments||antineoplaston a10, antineoplaston as2-1|
|Sponsor||Burzynski Research Institute|
|Start date||March 1996|
|End date||February 2008|
|Trial size||40 participants|
|Trial identifier||NCT00003526, BC-UP-2, CDR0000066570|
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 cancer of unknown primary origin.
Response rate based on tumor measurements at 12 weeks
Survival at 1, 2, and 5 years from the start of treatment
Male or female participants of any age.

|Official title||Phase II Study of Antineoplastons A10 and AS2-1 In Patients With Adenocarcinoma of Unknown Primary|
|Description||OBJECTIVES: - Provide treatment with antineoplastons A10 and AS2-1 for patients with incurable adenocarcinoma of unknown primary. - Describe response, tolerance to, and side effects of this regimen in these patients. OUTLINE: This is an open-label study. Patients receive gradually escalating doses of antineoplastons A10 and AS2-1 by intravenous injection 6 times daily until the maximum tolerated dose is reached. Treatment continues for at least 3 months in the absence of unacceptable toxicity or disease progression. Patients achieving complete response (CR) continue treatment for an additional 8 months after reaching CR. Tumors are measured every 2 months for 1 year and then every 3 months for 1 year. PROJECTED ACCRUAL: Approximately 20-40 patients will be accrued for this study.|
