Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recommended Dose of Plitidepsin in Combination With Bortezomib and Dexamethasone
Time Frame: After 28-day cycle
To determine the recommended dose (RD) of plitidepsin in combination with bortezomib and dexamethasone in patients with relapsed and/or refractory multiple myeloma (MM). To define the RD, patients will be evaluated for DLTs during the first 28-day cycle. The RD will be the highest DL at which fewer than two out of six (33%) of evaluable patients experience a DLT during the first 28-day cycle.
After 28-day cycle
Recommended Dose of Bortezomib in Combination With Plitidepsin and Dexamethasone
Time Frame: After 28-day cycle
To determine the recommended dose (RD) of plitidepsin in combination with bortezomib and dexamethasone in patients with relapsed and/or refractory multiple myeloma (MM). To define the RD, patients will be evaluated for DLTs during the first 28-day cycle. The RD will be the highest DL at which fewer than two out of six (33%) of evaluable patients experience a DLT during the first 28-day cycle.
After 28-day cycle
Recommended Dose of Dexamethasone in Combination With Plitidepsin and Bortezomib
Time Frame: After 28-day cycle
To determine the recommended dose (RD) of plitidepsin in combination with bortezomib and dexamethasone in patients with relapsed and/or refractory multiple myeloma (MM). To define the RD, patients will be evaluated for DLTs during the first 28-day cycle. The RD will be the highest DL at which fewer than two out of six (33%) of evaluable patients experience a DLT during the first 28-day cycle.
After 28-day cycle
Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs)
Time Frame: After 28-day cycle

DLTs were defined as:

Hematological Toxicity

  • Grade 3/4 neutropenia associated with fever or lasting>7 days related to the study treatment
  • Grade 3/4 thrombocytopenia accompanied by grade 3/4 hemorrhage
  • Extensive bone marrow (BM) infiltration, DLT was defined as grade 4 thrombocytopenia with grade 3/4 hemorrhage or grade 4 neutropenia lasting >7 days or with fever Non-hematological Toxicity
  • Grade 3/4 nausea and vomiting refractory to antiemetic therapy
  • Grade≥3 muscular Adverse events (AE) (myalgia, muscular weakness, muscle cramps, myopathy)
  • Grade≥3 alanine aminotransferase (ALT)/Aspartate aminotransferase (AST) lasting more than 1 week
  • Grade≥3 bilirubin increase
