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

NCT ID: NCT00773838

Last Updated: 2021-04-01

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 143 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2008-12-01
• Study Completion Date: 2012-04-09

Brief 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.

Detailed Description

The protocol has been amended to indicate that the Final Analysis is designated as the time when the primary endpoint of 29 responders has been met, or the time when all participants have discontinued treatment or have been enrolled in the study for at least 6 months (if the primary endpoint is not reached by this time). Following the Final Analysis, participants will be allowed to continue study treatment in an extension as long as they have not met the criteria for discontinuation, and will be followed for overall survival and serious AEs.

Conditions

• Blinding Strategy: NONE

Study Groups

Vorinostat + Bortezomib

Participants receive vorinostat 400 mg, orally, once daily (QD) on Days 1-14 of each 21-day treatment cycle and bortezomib 1.3mg/m\^2 intravenous (IV) injection QD on Days 1, 4, 8 and 11 of each 21-day treatment cycle for up to 26 cycles. Participants with progressive disease (PD) after 2 cycles of treatment or no change (NC) after 4 cycles of treatment receive additional treatment of Dexamethasone, 20 mg of total daily dose, orally on Days 1, 2, 4, 5, 8, 9, 11, and 12 of each 21-day treatment cycle for up to 26 cycles. Eligible participants could receive additional treatment on an extension.
