Clinical Trial: Antineoplaston Therapy in Treating Patients With Anaplastic Astrocytoma

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Phase II Study of Antineoplastons A10 and AS2-1 in Adult Patients With Anaplastic Astrocytoma

Brief Summary:

RATIONALE: Current therapies for adults with anaplastic astrocytomas that have not responded to standard therapy provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of adults with anaplastic astrocytomas that have not responded to standard therapy.

PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on adults with anaplastic astrocytomas that have not responded to standard therapy.


Detailed Summary:

OBJECTIVES:

  • To determine the efficacy of Antineoplaston therapy in patients with anaplastic astrocytomas that have not responded to standard therapy, 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 a anaplastic astrocytoma

OVERVIEW: This is a single arm, open-label study in which adults withanaplastic astrocytomas that have not responded to standard therapy receive gradually escalating doses of intravenous Antineoplaston therapy (Atengenal + Astugenal) 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 a complete or partial response or with stable disease may continue treatment.

To determine objective response, tumor size is measured utilizing MRI scans, which are 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.

PROJECTED ACCRUAL: A total of 20-40 patients will be accrued to this study

Current Primary Outcome: Number of Participants With Objective Response [ Time Frame: 12 months ]

Objective response rate per Response Assessment in Neuro-Oncology (RANO) for target lesions and assessed by MRI: Complete Response (CR), disappearance of all disease sustained for at least four weeks; Partial Response (PR), >=50% decrease in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions, sustained for at least four weeks; Stable Disease (SD), <50% decrease and <25% increase in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions, sustained for at least eight weeks; Progressive Disease (PD), >=25% increase in the sum of the products of of the greatest perpendicular diameters of all measurable enhancing lesions.
