Brief summary
This is a multi-center, open-label, single arm, non-comparative phase II trial, designed to evaluate the efficacy of plitidepsin in combination with bortezomib and dexamethasone in patients with Multiple Myeloma (MM) double refractory to bortezomib and lenalidomide.
Detailed description
This is a multi-center, open-label, single arm, non-comparative phase II trial, designed to evaluate the efficacy of plitidepsin in combination with bortezomib and dexamethasone in patients with MM double refractory to bortezomib and lenalidomide.The primary endpoint will be overall response rate (ORR), including stringent complete response (sCR), complete response (CR), very good partial response (VGPR) and partial response (PR). Approximately 64 evaluable patients will be needed for the evaluation of the primary endpoint, ORR. An early futility analysis will be performed with the efficacy data collected from the first 20 evaluable patients. The futility analysis will commence once patient number 20 has completed two full treatment cycles. Patient recruitment will not be halted during the conduct of this futility analysis.
Interventions
DRUGplitidepsin
Patients received plitidepsin as a 3-hour i.v. infusion at a dose of 5 mg/m2 on Days 1 and 15 every Four Weeks.

Inclusion criteria
1. Patients must give written informed consent (IC) in accordance with institutional and local guidelines. 2. Age ≥ 18 years. 3. Patients must have a confirmed diagnosis of MM according to the Durie and Salmon criteria. 4. Patients must have measurable disease defined as any of the following: 1. Serum M-protein ≥ 0.5 g/dL or ≥ 0.2 g/24-h urine light chain (UFLC) excretion. 2. In patients who lack measureable M-protein in serum or urine, i.e., serum M-protein \< 0.5 g/dL and urine M-protein \< 0.2 g/24 h, serum free light chain (SFLC) levels are most informative. SFLC levels can be used only if the baseline SFLC ratio is abnormal (\<0.26 or \>1.65), indicating clonality. In addition, the baseline SFLC level must be ≥10 mg/dl of the appropriate involved light chain isotype. 3. When applicable, measurable soft tissue plasmacytoma ≥ 2 cm, by either physical examination and/or applicable radiological evaluation (i.e., magnetic resonance imaging \[MRI\], computed tomography \[CT\]-scan). 5. Prior autologous and/or allogeneic hematopoietic stem cell transplantation (HSCT) patients are allowed. Patients must not have acute/chronic graft-versus-host disease (GVHD) or be receiving immunosuppressive therapy at least 90 days before the onset of treatment with the trial drug(s). 6. Patients must have received previous treatment with bortezomib and lenalidomide and be refractory to both. 7. Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤ 2. 8.

Hemoglobin ≥ 8 g/dL. 2. Absolute neutrophil count (ANC) ≥ 1,000 cells/mm3 (1.0 x 109/L) (≥ 0.5 x 109/L if due to extensive bone marrow \[BM\] involvement by ≥ 50% of plasma cells in BM biopsy). Screening of ANC should be independent of granulocyte- and granulocyte/macrophage-colony stimulating factor (G-CSF and GM-CSF) support for at least one week and of pegylated G-CSF for at least two weeks. 3. Platelet count ≥ 50,000/mm3 (50.0 x 109/L) for patients in whom \< 50% of the BM nucleated cells are plasma cells. 4. Platelet count ≥ 25,000/mm3 (25.0 x 109/L) for patients in whom ≥ 50% of BM nucleated cells are plasma cells. 5. Serum total bilirubin \< 1.5 x institutional upper limit of normal (ULN) (except when Gilbert syndrome is clearly documented and other liver function tests are within normal levels). 6. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3.0 x institutional ULN and alkaline phosphatase (AP) ≤ 2.5 x institutional ULN. 7.

Evidence of non-childbearing status for women of childbearing potential (WOCBP): WOCBP must have a negative serum or urine pregnancy test within seven days prior to enrolment and must agree to use a highly effective contraceptive measure throughout the trial and during six months after treatment discontinuation. Male patients enrolled in the study should also use contraceptive methods during and after treatment discontinuation. 11. Left ventricular ejection fraction (LVEF) ≥ 45%. 12. Patients must have a BM assessment within three weeks prior to enrolment.

Percentage of Participants With Progression Disease at 12 Months
Progression disease was defined as documented PD or death due to PD. Progressive disease (PD): 25% increase from the lowest response value in any of the following: serum M-protein, urine M-protein, BM plasma cell percentage, or difference in the kappa and lambda FLC. PD also diagnosed when an increase size or new bone lesions.
Time frame: From the date of the first infusion to the date of documented PD or death due to PD, up to 12 months
Population: 1 died without any valid tumor assessment done~1 discontinued treatment-related AEs

Percentage of Participants With Progression-free Survival at 12 Months
Progression-free survival (PFS) was defined as the time, in months, from the date of first drug administration to the date of documented PD, or death (of any cause). If any patient was lost to follow-up before PD or received another antitumor therapy, PFS was to be censored on the date of the last tumor assessment. If there were no tumor assessments, these parameters were to be censored on the date of the first drug administration Progressive disease (PD): 25% increase from the lowest response value in any of the following: serum M-protein, urine M-protein, BM plasma cell percentage, or difference in the kappa and lambda FLC.
