|Gastrinoma Glucagonoma Insulinoma Metastatic Gastrointestinal Carcinoid Tumor Pancreatic Polypeptide Tumor Pulmonary Carcinoid Tumor Recurrent Gastrointestinal Carcinoid Tumor Recurrent Islet Cell Carcinoma Regional Gastrointestinal Carcinoid Tumor Somatostatinoma||Drug: romidepsin Other: laboratory biomarker analysis||Phase 2|
|Study Design:||Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||Phase II Study of Depsipeptide in Metastatic Neuroendocrine Tumors|
- Objective response rate [ Time Frame: Up to 4 weeks ]Frequency of response will be estimated with a 95% confidence interval.
- Incidence of toxicity [ Time Frame: Up to 4 weeks ]
|Study Start Date:||March 2004|
|Primary Completion Date:||October 2004 (Final data collection date for primary outcome measure)|
Experimental: 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.
Other Names:Other: laboratory biomarker analysis
I. Determine objective response rate in patients with locally advanced or metastatic neuroendocrine tumors treated with FR901288 (romidepsin).
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.
IV. To perform histone acetylation assay in cytospins from peripheral blood mononuclear cells (PBMCs) to correlate with disease response and with immunologic parameters.
V. To quantify gene expression by Real Time PCR of type 1 and type 2 cytokines, co-stimulatory molecules, and adhesion molecules in PBMCs obtained from the pre-, during-, and post-treatment blood samples.
VI. To perform a multicolor flow cytometric analysis on fresh blood to assess activation of lymphocyte subsets and presence of co-stimulatory and adhesion molecules.
VII. To perform in vitro functional assays for innate as well as antigen-specific T cell immune responses in PBMCs obtained from the pre-, during-, and post-treatment blood samples.
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 complete remission (CR) receive 2 additional courses beyond CR.
Patients are followed at 2-4 weeks.
