Trisenox, Ascorbic Acid and Bortezomib in Patients With Relapsed/Refractory Multiple Myeloma

Stopped early · Phase 1

Conditions studied: Multiple Myeloma

In brief

This is a phase I dose escalation study to estimate the maximum tolerated dose (MTD) of the novel combination of Arsenic, Ascorbic Acid and Velcade, followed by a phase II study conducted using the MTD estimated from the phase I portion.

You may qualify if…

• Diagnosis of relapsed/refractory multiple myeloma.
• Patients must have measurable disease, defined as localized plasmacytoma, detectable M-spike by serum protein electrophoresis (SPEP) and/or urine protein electrophoresis (UPEP), or free light chain assay, bone lytic lesions and/or bone marrow infiltration with atypical plasma-cells.
• Patients must be at least four weeks since their prior therapy. Patients will not be excluded because of any prior regimen they have received as long as they meet other requirements.
• Adequate organ function, patients with elevated creatinine due to myeloma are not excluded
• Eastern Cooperative Oncology Group (ECOG) performance status 0-2
• Serum potassium greater than 4.0 milliequivalent (mEq)/dL and serum magnesium greater than 1.8 mg/dL. If these electrolytes are below the specified limits on the baseline laboratory tests, supplemental electrolytes should be administered to bring the serum concentrations to these levels before administering arsenic trioxide.

You may not qualify if…

• Patients may not be receiving any other investigational agents.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to Bortezomib, Trisenox, Ascorbic acid, or other agents used in the study.
• Corrected QT interval (QTc) interval greater than 460 msec in the presence of serum potassium greater than or equal to 4.0 mEq/L and magnesium greater than or equal to 1.8 mg/dL, or underlying conduction disease that prevents measurement of the QTc interval.
• History of ventricular tachycardia or any cardiac arrhythmia requiring the placement of an automated intraventricular cardiac defibrillator or therapy with class I or class II antiarrhythmic drug.
• Ejection fraction (EF) by multigated acquisition (MUGA) scan less than 35%.
