Brief summary
RATIONALE: Interferon alfa may interfere with the growth of cancer cells. Interleukin-6 may stimulate the white blood cells to kill cancer cells. Giving interferon alfa together with interleukin-6 may kill more cancer cells. PURPOSE: This clinical trial is studying the side effects and how well giving interferon alfa together with interleukin-6 works in treating patients with recurrent multiple myeloma.
Detailed description
OBJECTIVES: * Determine the response rate in patients with recurrent multiple myeloma treated with recombinant interferon alfa and recombinant interleukin-6. * Determine the safety and optimal dose of this regimen in these patients. * Determine the toxicity of this regimen in these patients. * Determine the impact of this regimen on clonogenic growth of myeloma cells in serial in vitro assays. OUTLINE: This is a pilot study. Patients receive recombinant interferon alfa subcutaneously (SC) once daily. Beginning 1 month later, patients also receive recombinant interleukin-6 SC once daily. Treatment continues for up to 6 months in the absence of disease progression or unacceptable toxicity. PROJECTED ACCRUAL: A total of 27 patients will be accrued for this study.

|---|---|
| Interleukin-6 and Interferon-α Subjects will be started on recombinant interferon-α at a dose of 3 million units SQ daily, escalating the dose by 1 million units every week as tolerated to a maximum dose of 3 million units/m2/day. Following a minimum of one month of interferon therapy with two weeks on a stable dose, subjects will begin recombinant interleukin-6 therapy at a dose of 2.5 ug/kg/day.

Outcome results
Impact of Treatment on Growth of Myeloma Cells
Percentage change in growth of in vitro myeloma cells from baseline to end of study.
Time frame: Day 0, Day 14, Months 1, 2, 4, and 6 of combined therapy, and end of study
Population: Zero participants tolerated protocol therapy and the research sample blood draws were therefore not completed as planned. Because of this, the data from this outcome could not be collected.
Optimal Dose of Interleukin-6
Maximum tolerated dose found using a standard 3+3 dose escalation model.
Time frame: Up to 5 months
Population: This outcome cannot be evaluated as zero participants tolerated the study regimen. All participants were enrolled on the 2.5 mg arm and a maximum tolerated dose was not found.
Response Rate as Assessed by Number of Participants With Partial or Complete Response by Bladé Criteria.
Number of participants with partial or complete response by Bladé criteria where partial response is defined as a \>= 50% decrease in serum paraprotein or 90% decrease in urinary light chains (for participants without measurable serum paraprotein). Complete response is defined as negative serum and urine immunofixation and a bone marrow aspirate with \< 5% plasma cells.
