Study Overview
Brief Summary
Phase II trial to study the effectiveness of romidepsin in treating patients who have locally advanced or metastatic neuroendocrine tumors. Drugs used in chemotherapy, such as romidepsin, work in different ways to stop tumor cells from dividing so they stop growing or die.
Detailed Description
PRIMARY OBJECTIVES:
I. Determine objective response rate in patients with locally advanced or metastatic neuroendocrine tumors treated with FR901288 (romidepsin).
SECONDARY OBJECTIVES:
I. Determine the toxicity of this drug in these patients. II. To measure serum tumor markers (pancreastatin, gastrin, pancreatic polypeptide, glucagon, substance-P, neurotensin, calcitonin, somatostatin, vasoactive intestinal peptide, gastrin releasing polypeptide, ACTH) depending on the tumor type pre-, during-, and post-treatment.
III. To perform a nuclear medicine functional imaging scan (octreoscan) to evaluate the disease status pre-, during-, and post-treatment.

Arms & Interventions
Treatment (romidepsin)
Patients receive romidepsin IV over 4 hours on days 1, 8, and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving CR receive 2 additional courses beyond CR.
Intervention: romidepsin (Drug)
Treatment (romidepsin)
Patients receive romidepsin IV over 4 hours on days 1, 8, and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. Patients achieving CR receive 2 additional courses beyond CR.
Intervention: laboratory biomarker analysis (Other)
