| NCT00555906 | An Investigational Drug, Palbociclib (PD-0332991), Is Being Studied In Combination With Velcade And Dexamethasone In Patients With Multiple Myeloma. Patients Must Have Received Prior Treatment For Multiple Myeloma. | PHASE2 | COMPLETED | 53 | — | — | Jan 1, 2008 | Mar 1, 2013 | Mar 19, 2015 | 19 | United States, Czechia +1 |
MTD=highest dose level for which no more than 1 out of 6 participants experienced dose-limiting toxicity (DLT). DLT=any of the following treatment-related events: Absolute neutrophil count (ANC) less than (\<)1000/microliter (mcL) (Grade 3 neutropenia) associated with documented infection/fever \>=38.5degrees Celsius (C); Grade \>=3 nonhematologic treatment-related toxicity, except those that were not maximally treated or considered tolerable, Grade 3 corrected QT interval (QTc) prolongation (QTc \>500 millisecond \[msec\]) in asymptomatic participants even after repeat testing to exclude confounding factors and correction of reversible causes; Delay in the administration of Cycle 2 for more than 1 week of the planned date due to platelet count \<25,000/mcL and/or ANC \<500/mcL, or due to prolonged nonhematologic toxicities of Grade \>=3; Inability to deliver at least 80 percent (%) of the planned PD 0332991 or bortezomib doses during Cycle 1 due to toxicity.
RP2D was determined based on the MTD, safety and tolerability profile of the study treatment.
OR: confirmed stringent complete response(sCR),complete response(CR),very good partial response(VGPR) or partial response(PR) as per International Myeloma Working Group Uniform Response Criteria (IMWGURC). sCR: normal serum free light chain (FLC) ratio, absence of clonal cells in bone marrow. CR: disappearance of any soft tissue plasmacytomas, \<5 percent (%) plasma cells in bone marrow, negative immunofixation on serum, urine. VGPR: serum, urine M-protein detectable by immunofixation but not on electrophoresis, \>= 90% reduction in serum M-protein, \<100 mg/24 hour (hr) urine M-protein. PR: \>=50% reduction in serum M-protein, reduction in 24-hr urinary M-protein by \>=90% or to \<200 mg/24 hr, \>=50% decrease in difference between involved and uninvolved FLC levels if serum, urine M-protein were unmeasurable, \>= 50% reduction in plasma cells, provided baseline bone marrow plasma cell was \>=30% if serum, urine M-protein were unmeasurable and serum free light assay was unmeasureable.
