Phase II Study of Antineoplastons A10 and AS2-1 in Patients With Primary Central Nervous System Lymphoma
antineoplaston A10
+ antineoplaston AS2-1
+ alternative product therapy
Treatment Study
Summary
OBJECTIVES: Assess the safety and possible effectiveness of antineoplastons A10 and AS2-1 in patients with serious or immediately life-threatening primary central nervous system lymphoma. Describe response to, tolerance to, and side effects of this regimen in these patients. OUTLINE: This is an open-label study. Patients receive gradually escalating doses of intravenous antineoplaston A10 and antineoplaston AS2-1 6 times per day until the maximum tolerated dose is reached. Treatment continues for at least 12 months in the absence of disease progression or unacceptable toxicity. After 12 months, patients with responding or stable disease may continue treatment. Tumors are measured every 2 months for 6 months, every 3 months for 2 years, every 6 months for years 3 and 4, and then annually for years 5 and 6. PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study.
