Details and patient eligibility

About

Phase II trial to study the effectiveness of combining interleukin-12 and interferon alfa in treating patients who have metastatic malignant melanoma. Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill cancer cells. Interferon alfa may interfere with the growth of the cancer cells. Combining interleukin-12 and interferon alfa may kill more tumor cells.

Full description

PRIMARY OBJECTIVES:

I. To estimate the clinical response rates in patients with metastatic malignant melanoma treated with rhIL-12 and interferon alfa-2b.

II. To estimate the progression-free survival in patients with metastatic malignant melanoma treated with rhIL-12 and interferon alfa-2b.

SECONDARY OBJECTIVES:

I. To measure serum levels of interferon-gamma. II. To measure levels of JAK-STAT signaling intermediates in patient PBMCs and tumor samples.

III. To analyze interferon-alpha-induced STAT signaling in patient PBMCs. IV. To determine the expression of IFN-regulated genes in patient PBMCs and tumor tissues.

V. To determine the pattern of gene expression induced by treatment with IL-12 and interferon-alpha using DNA microarray techniques in patient PBMCs.

OUTLINE: This is a multicenter study.

Patients receive interleukin-12 IV over 5-15 seconds on day 1 and interferon alfa subcutaneously on days 2-6. Treatment repeats every 2 weeks in the absence of unacceptable toxicity. Patients are reassessed after 6 courses. Patients with a complete response receive 2 additional courses. Patients with a partial response or stable disease continue treatment in the absence of disease progression.

Patients are followed every 3 months for 1 year and then every 6 months for 1 year.

Inclusion and exclusion criteria

Inclusion Criteria:

Histological or cytological diagnosis of cutaneous melanoma and clinical evidence of distant, metastatic, non-resectable regional lymphatic, or extensive in transit recurrent disease
Patients must have measurable disease; measurable disease is defined as the presence of at least one measurable lesion; if the measurable disease is restricted to a solitary lesion, its neoplastic nature should be confirmed by cytology/histology; measurable lesions are defined as lesions that can be accurately measured in at least one dimension with the longest diameter >= 20 mm using conventional techniques or >= 10 mm with spiral CT scan
- Lesions that are considered intrinsically non-measurable include the following:
  - Bone lesions;
  - Leptomeningeal disease;
  - Ascites;
  - Pleural/pericardial effusion;
  - Inflammatory breast disease;
  - Lymphangitis cutis/pulmonis;
  - Abdominal masses that are not confirmed and followed by imaging techniques;
  - Lytic lesions;
  - Lesions that are situated in a previously irradiated area
No history of peripheral neuropathy, brain metastases or other central nervous system disease
No history of/active autoimmune disease, hemolytic anemia or concurrent requirement for corticosteroids, including topical or inhaled
No hepatitis BSAg, known HIV disease or other major active illness; patients with risk factors for HIV should be tested; patients with these illnesses are more likely to experience significant side effects from the study treatment
No history of severe peptic ulcer disease or gastrointestinal bleeding unless there is objective evidence that the condition is inactive or resolved
No uncontrolled or severe cardiovascular disease, diabetes, pulmonary disease, or infection
No chemotherapy, radiotherapy, or anti-hormonal therapy within three weeks prior to the initiation of therapy on this study
No prior therapy with IL-12
No prior therapy with IFN-alpha for metastatic disease (e.g., biochemotherapy); prior adjuvant therapy with IFN-a is acceptable as long as the patient remained disease-free for 12 months or longer following the last IFN-a treatment
No prior cytokine therapy for metastatic disease (e.g., high-dose IL-2)
No more than one prior chemotherapy regimen
CTC (ECOG) performance status 0-1
Non-pregnant, non-nursing; treatment under this protocol would expose an unborn child to significant risks; women and men of reproductive potential should agree to use an effective means of birth control; women of child-bearing age will undergo pregnancy testing
ANC >= 1500/μL
Platelets >= 100,000/μL
Hemoglobin > 9 g/dL (may be post transfusion or may receive EPO)
U-HCG or Serum HCG Negative (if patient of child-bearing potential)
