What was measured

Objective RR was defined as percentage (%) of participants with complete response (CR: disappearance of original monoclonal (M) paraprotein from blood \& urine on at least 2 determinations for at least 6 weeks (WKs) by immunofixation studies, \<5% plasma cells in bone marrow on at least 1 determination, no increase in size/number of lytic bone lesions (LBLs) \& disappearance of soft tissue plasmacytomas (STP) for at least 6 WKs on skeletal survey (SS) if available) or partial response (PR: ≥50% reduction in serum M protein for at least 2 determinations 6 WKs apart, if present, reduction in 24-hour urinary light chain excretion by ≥90% or ≤200 mg for at least 2 determinations 6 WKs apart, ≥50% reduction in STP size for at least 6 WKs, \& no increase in size/number of LBLs on SS if available) as assessed by Independent Adjudication Committee (IAC) per European Blood \& Marrow Transplant (EBMT) criteria. To report RR \& 95% confidence intervals (CIs), exact test of binomial parameter was used.

Analysis population: All participants who received at least one dose of study treatment

Groups in this outcome

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.
