Arsenic Trioxide Plus Vitamin C in Treating Patients With Recurrent or Refractory Multiple Myeloma

December 14, 2016 updated by: University of Miami

Phase I/II Trial of Arsenic Trioxide (As2O3) With Ascorbic Acid in the Treatment of Relapsed/Refractory Multiple Myeloma

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Vitamin C may increase the effectiveness of arsenic trioxide by making cancer cells more sensitive to the drug.

PURPOSE: Phase I/II trial to determine the effectiveness of arsenic trioxide plus vitamin C in treating patients who have recurrent or refractory multiple myeloma.

Study Overview

Detailed Description

OBJECTIVES:

  • Determine the maximum tolerated dose of arsenic trioxide when administered with ascorbic acid in patients with recurrent or refractory multiple myeloma.
  • Determine the therapeutic efficacy of this treatment combination in these patients.
  • Determine the expression of MDR and Bcl-xL genes and the intracellular levels of GSH in these patients before and after this treatment regimen and assess whether these measures have prognostic value.

OUTLINE: This is a multicenter, dose-escalation study of arsenic trioxide.

  • Phase I: Patients receive arsenic trioxide IV over 1-4 hours and ascorbic acid IV over 5-10 minutes on days 1-5 weekly for 5 weeks. Treatment continues every 7 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of arsenic trioxide until the maximum tolerated dose (MTD) is reached. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

  • Phase II: Patients receive the MTD of arsenic trioxide with ascorbic acid as outlined above.

Patients are followed monthly for up to 5 years.

PROJECTED ACCRUAL: A total of 31-43 patients (6-18 for phase I and 16-25 for phase II) will be accrued for this study within 2.5 years.
