Multiple Myeloma Clinical Trial
Bortezomib, Ascorbic Acid, and Melphalan in Treating Patients With Newly Diagnosed Multiple Myeloma
Summary
RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Ascorbic acid may help melphalan work better by making cancer cells more sensitive to the drug. Giving bortezomib together with ascorbic acid and melphalan may kill more cancer cells.
PURPOSE: This phase II trial is studying how well giving bortezomib together with ascorbic acid and melphalan works in treating patients with newly diagnosed multiple myeloma.
Full Description
OBJECTIVES:
Primary
Determine the overall response rate (combined complete response [CR], near CR, partial response [PR], and minimal response [MR]) and time to progression of disease in patients with newly diagnosed multiple myeloma treated with bortezomib, ascorbic acid, and melphalan.
Assess the safety and tolerability of this regimen in these patients.
Secondary
Assess the time to response in these patients.
Determine progression-free and overall survival of these patients.
Assess time to disease progression among subjects who continue to maintenance treatment with bortezomib.
OUTLINE: This is an open-label study.
Induction therapy: Patients receive bortezomib IV on days 1, 4, 8, and 11 and oral melphalan and oral ascorbic acid on days 1-4. Treatment repeats every 28 days to maximum response [MR] or for at least 8 courses in the absence of disease progression or unacceptable toxicity. Patients with responding disease receive an additional 2 courses of induction therapy beyond MR and proceed to maintenance therapy. Patients with stable disease or without a maximum reduction in their paraprotein after 8 courses of induction therapy are eligible to receive maintenance therapy.
Maintenance therapy: Patients receive bortezomib IV on days 1 and 15. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 3 months.
PROJECTED ACCRUAL: A total of 35 patients will be accrued for this study.
