Summary

This study will evaluate the safety and efficacy of atiprimod treatment in patients with low to intermediate grade neuroendocrine carcinoma who have metastatic or unresectable local-regional cancer and who have either symptoms (diarrhea, flushing and/or wheezing) despite standard therapy (octreotide) or progression of neuroendocrine tumor(s).

Detailed description

For carcinoid, despite the many cytotoxic chemotherapy trials that have been conducted, no regimen has demonstrated a response rate of more than 20% using the criterion of a 50% reduction of bidimensionally measurable disease. In the more recently reported ECOG phase III study of chemotherapy in carcinoid tumors (E1281), patients were randomly assigned to treatment with 5-fluorouracil (5FU) plus doxorubicin or 5FU plus streptozocin. The median progression free survival durations were disappointing. They were 4.5 months in the 5FU plus doxorubicin arm and 5.3 months in the 5FU plus streptozocin arm. Overall survival durations recorded in the trial were also suboptimal at 15 and 24 months respectively. There is no clear survival benefit for cytotoxic chemotherapy. This is a phase II, multi-center, open-label study of the safety and efficacy of atiprimod treatment in patients with low to intermediate grade neuroendocrine carcinoma who have metastatic or unresectable local-regional cancer and who have either symptoms (diarrhea, flushing and/or wheezing) despite standard therapy (octreotide) or progression of neuroendocrine tumor(s) (defined as the appearance of one or more new lesions or a 20% increase in the sum of the longest diameter of target lesions during the 6 months prior to enrollment). A maximum of 40 evaluable patients will be enrolled in this study. Atiprimod will be administered orally as a single daily dose of 120 mg/day for 14 days, followed by a 14-day treatment-free period (i.e., 1 treatment cycle = 28 days).
