About

Current therapies for Recurrent or Refractory Waldenstrom's Macroglobulinemia provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of Recurrent or Refractory Waldenstrom's Macroglobulinemia.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with Recurrent or Refractory Waldenstrom's Macroglobulinemia.

Full description

Recurrent or Refractory Waldenstrom's Macroglobulinemia 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 Recurrent or Refractory Waldenstrom's Macroglobulinemia, 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 Recurrent or Refractory Waldenstrom's Macroglobulinemia.
• 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.

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers
