Study of Vorinostat (MK0683), an Histone Deacetylase (HDAC) Inhibitor in Combination With Bortezomib in Patients With Relapsed or Refractory Multiple Myeloma (MK-0683-095)

• Status: Completed
• Trial end date: 2012-04-09
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to evaluate the clinical activity of vorinostat in combination with bortezomib in participants with relapsed or refractory multiple myeloma after at least 2 prior treatment regimens. The primary objective is to define the objective response rate (RR) associated with the administration of vorinostat in combination with bortezomib to patients with relapsed and refractory multiple myeloma after at least 2 prior treatment regimens. The primary hypothesis of the study is the administration of vorinostat in combination with bortezomib will result in a clinically meaningful rate of objective response.
