Antineoplaston Therapy in Treating Patients With Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma

Phase II Study of Antineoplaston A10 and AS2-1 in Patients With Non-Hodgkin's Lymphoma, Intermediate Grade

Current therapies for Refractory or Recurrent Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma 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 or Recurrent Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Refractory or Recurrent Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma.

Refractory or Recurrent Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma patients receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) until the maximum tolerated dose is reached. Treatment continues up to12 months in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:

• To determine the efficacy of Antineoplaston therapy in patients with Refractory or Recurrent Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma, 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 or Recurrent Intermediate-Grade Stage II - IV Non-Hodgkin's Lymphoma.
• To determine objective response, tumor size is measured utilizing physical examination, radiologic studies, and bone marrow biopsies as necessary, 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.

DISEASE CHARACTERISTICS:

• Histologically proven stage II, III, or IV intermediate-grade non-Hodgkin's lymphoma that has not responded to or has relapsed after a standard primary chemotherapy regimen plus at least 1 standard second-line salvage chemotherapy regimen NOTE: A new classification scheme for adult non-Hodgkin's lymphoma has been adopted by PDQ. The terminology of "indolent" or "aggressive" lymphoma will replace the former terminology of "low", "intermediate", or "high" grade lymphoma. However, this protocol uses the former terminology.
