| NCT00401843 | A Study of the Safety and Efficacy of CNTO 328 and Bortezomib to Bortezomib Alone in Patients With Relapsed or Refractory Multiple Myeloma | PHASE2 | COMPLETED | 307 | — | — | Nov 28, 2006 | Sep 24, 2019 | Nov 19, 2019 | 80 | United States, Belgium +16 |
CR was assessed using EMBT criteria: disappearance of the original monoclonal paraprotein from the blood and urine on at least 2 determinations for a minimum of 6 weeks by immunofixation studies, \<5% plasma cells in the bone marrow on at least 1 determination, if skeletal survey is available: no increase in the size or number of lytic bone lesions (development of a compression fracture does not exclude response), disappearance of soft tissue plasmacytomas for at least 6 weeks.
Progression-free survival was defined as the time interval between randomization and the first documented sign of disease progression (including relapse from complete response \[CR\]) by the European Bone Marrow Transplant (EBMT) criteria or death, whichever occurred first. Relapse from CR requires at least 1 of the following: Reappearance of serum or urinary M-protein on immunofixation or routine electrophoresis, confirmed by at least 1 further investigation and excluding oligoclonal immune reconstitution; Greater than or equal to (\>=) 5 percent (%) plasma cells either in a bone marrow aspirate or on trephine bone biopsy; Development of new lytic bone lesions or soft tissue plasmacytomas or definite increase in the size of residual bone lesions (development of a compression fracture does not exclude continued response and may not indicate progression); Development of hypercalcemia not attributable to any other cause.
An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; lifethreatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
