简要总结
RATIONALE: Peginterferon (PEG-interferon) alfa-2b may stop the growth of cancer by stopping blood flow to the tumor.
PURPOSE: Phase II trial to study the effectiveness of PEG-interferon alfa-2b in treating patients who have stage IV melanoma.
详细描述
OBJECTIVES:
- Determine the ability of low-dose PEG-interferon alfa-2b to suppress plasma basic fibroblast growth factor (b-FGF) levels to normal in patients with metastatic melanoma over-expressing b-FGF.
- Determine the antitumor effect of this drug, in terms of progression-free and overall survival and tumor response, in these patients.
- Correlate tumor activity of this drug with b-FGF and vascular endothelial growth factor levels in the plasma and urine of these patients.
- Determine the safety profile of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive PEG-interferon alfa-2b subcutaneously (SC) once weekly. Treatment continues until basic fibroblast growth factor level is suppressed to normal or until a maximum weekly dose is reached. If there is disease progression, patients then discontinue treatment. If there is no disease progression, patients receive PEG-interferon alfa-2b SC weekly for up to 1 year in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months for 2 years and then every 6 months for 1 year.

结局指标
主要结局
Plasma b-FGF Level Response
时间窗: assessed every 3 weeks until the suppression of plasma b-FGF level to normal, then every 6 weeks until the completion of 12 months of treatment, and upon treatment discontinuation
The primary endpoint was the suppression of plasma b-FGF level with low dose peginterferon alfa-2b. A clinically important reduction of plasma b-FGF levels was determined to be a level less than or equal to 7.5 pg/mL. A patient was considered to have a suppressed plasma b-FGF level, if the patient experienced the clinically significant reduction (less than or equal to 7.5 pg/mL) of plasma b-FGF levels for two consecutive determinations which were at least three weeks apart. This was considered as a b-FGF response.
次要结局
- Non-progression Rate (Clinical Response to Peginterferon Alfa-2b)(assessed every 9 weeks until suppression of plasma b-FGF level to normal, every 12 weeks until the completion of 12 months of treatment, >= 4 weeks after documented response. After off treatment, every 3 months if <2 years, and every 6 months if 2-3 years)
- Progression Free Survival(assessed every 9 weeks until suppression of plasma b-FGF level to normal, every 12 weeks until the completion of 12 months of treatment, >= 4 weeks after documented response. After off treatment, every 3 months if <2 years, and every 6 months if 2-3 years)
- Overall Survival(assessed every 3 months if <2 years, and every 6 months if 2-3 years)
