Spots Global Cancer Trial Database for Arsenic Trioxide, Thalidomide, Dexamethasone, and Ascorbic Acid in Treating Patients With Relapsed or Refractory Multiple Myeloma

Study Description

Brief Summary: RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, dexamethasone, and ascorbic acid, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. Sometimes when chemotherapy is given, it does not stop the growth of cancer cells. The cancer is said to be resistant to chemotherapy. Giving arsenic trioxide together with chemotherapy may reduce drug resistance and allow the cancer cells to be killed. Thalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Giving arsenic trioxide together with thalidomide, dexamethasone, and ascorbic acid may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with thalidomide, dexamethasone, and ascorbic acid works in treating patients with relapsed or refractory multiple myeloma.

Detailed Description: OBJECTIVES: * Determine the safety and side effects of arsenic trioxide administered in combination with thalidomide, dexamethasone, and ascorbic acid in patients with relapsed or refractory multiple myeloma. * Determine, preliminarily, the anticancer effects of this regimen in these patients. * Determine the duration of anticancer effects in patients treated with this regimen. * Determine the effect of this regimen on bone and immune function in these patients. OUTLINE: Patients receive arsenic trioxide IV continuously and oral ascorbic acid once daily on days 1-5 in week 1 and twice weekly in weeks 2-12 and oral thalidomide once daily in weeks 1-14. Treatment with arsenic trioxide, ascorbic acid, and thalidomide repeats every 14 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients also receive oral dexamethasone once daily on days 1-4. Treatment with dexamethasone repeats every 28 days. PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
