Phase II Study of Antineoplastons A10 and AS2-1 in Patients With Metastatic or Incurable Neuroendocrine Tumors


OBJECTIVES:

- Provide treatment with antineoplastons A10 and AS2-1 for patients with metastatic or
incurable neuroendocrine tumors.

- 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 2 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.
