Phase I/II Study of Arsenic Trioxide (Trisenox), Ascorbic Acid and Bortezomib Combination Therapy in Patients With Relapsed/Refractory Multiple Myeloma
Despite the fact the high dose therapy and autologous transplant can prolong life in
patients with multiple myeloma (MM), in most studies there appears to be a continuously
declining event free survival following auto-transplant indicating that few patients will be
cured with this approach. A high percentage of patients the relapse in the post transplant
setting will not be candidate for additional chemotherapy. We therefore, are investigating
novel strategies for controlling their disease in the post transplant setting. The key
theoretical issue for this study is whether concomitant Trisenox would permit the use of
less toxic doses of Velcade, resulting in a less toxic but equally effective regimen.
Phase I of this study uses dose escalation to estimate the maximum tolerated dose of
Arsenic, Ascorbic Acid and Velcade. Phase II is a subsequent treatment phase using the
maximum tolerated dose from Phase I. In the absence of treatment delays due to adverse
events, treatment may continue for 6 cycles, plus two additional cycles if patient has
achieved a good response.
