Summary

This randomized phase III trial studies octreotide acetate and recombinant interferon alfa-2b to see how well it works compared to octreotide acetate and bevacizumab in treating patients with high-risk neuroendocrine tumors that have spread to other places in the body (metastatic) or spread from where it started to nearby tissue or lymph nodes (locally advanced). Octreotide acetate and recombinant interferon alfa-2b may interfere with the growth of tumor cells and slow the growth of cancer. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving octreotide acetate together with recombinant interferon alfa-2b is more effective than giving octreotide acetate together with bevacizumab in treating patients with neuroendocrine tumor.

Detailed description

PRIMARY OBJECTIVES: I. To compare central review-based progression-free survival in poor prognosis carcinoid patients treated with either depot octreotide (octreotide acetate) plus bevacizumab, or depot octreotide plus interferon (recombinant interferon alfa-2b). SECONDARY OBJECTIVES: I. To compare overall survival, time to treatment failure and traditionally reported progression-free survival in poor prognosis carcinoid patients treated with either depot octreotide plus bevacizumab, or depot octreotide plus interferon. II. To compare objective response (confirmed and unconfirmed complete response \[CR\] and partial response \[PR\]) in poor prognosis carcinoid patients treated with either depot octreotide plus bevacizumab, or depot octreotide plus interferon. III. To compare the toxicity profile of patients treated with these two regimens. TERTIARY OBJECTIVES: I. To assess the prognostic and predictive value of vascular endothelial growth factor (VEGF) expression in relation to progression-free survival and treatment effect. II. To compare response of 5HIAA, chromogranin A and neuronspecific enolase among patients with elevated levels at baseline between patients treated with octreotide plus interferon versus octreotide plus bevacizumab. III. To assess and compare the prognostic and predictive value of the combination of In-111 pentetreotide somatostatin-receptor scintigraphy (SRS) and computed tomography (CT) vs. CT in relation to progression-free survival (PFS). IV. To assess and compare the prognostic and predictive value of the combination of SRS and CT vs. CT in relation to overall survival (OS) and time to treatment failure (TTF). OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive octreotide acetate intramuscularly (IM) and bevacizumab intravenously (IV) over 30-90 minutes on day 1. ARM II: Patients receive octreotide acetate IM on day 1 and recombinant interferon alfa-2b subcutaneously (SC) on days 1, 3, 5, 8, 10, 12, 15, 17, and 19. Treatment in both arms repeats every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 2-6 months for up to 3 years.
