Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Near Complete Response (nCR)/ Complete Response (CR) Rateafter 24 weeks (8 cycles; cycle = 21 days)

nCR plus CR rate after 8 cycles of therapy as defined by the modified European Society for Bone and Marrow Transplantation (EBMT) criteria per investigator assessment as the proportion of participants with nCR or CR as their best overall response.

Secondary Outcome Measures
NameTimeMethod
Overall Response Rate (ORR)24 weeks (8 cycles; cycle = 21 days)

ORR is defined as the proportion of participants with CR, nCR or partial response (PR) based on modified EBMT criteria per investigator assessment

Progression Free Survival (PFS)duration of study up to approx. 4 years

PFS is defined as time from first dose of study treatment to progression or death due to any cause, based on modified European Society for Bone and Marrow Transplantation (EBMT) criteria per Investigator's assessment

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: AUClast, AUC0-24h, AUC0-48h, AUCinfPredose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h, 48h post dose

PK sample collection was performed in subjects who agreed to blood samplings for the PK assessments of PAN and BTZ. The order of administration of the 3 study treatment components was 1) PAN, 2) Dex, and 3) BTZ.

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: CmaxPredose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h, 48h post dose

Cmax: The maximum (peak) observed plasma concentration. PK sample collection was performed in subjects who agreed to blood samplings for the PK assessments of PAN and BTZ. The order of administration of the 3 study treatment components was 1) PAN, 2) Dex, and 3) BTZ.

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: TmaxPredose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h, 48h post dose

Tmax: The time to reach maximum (peak) plasma concentration. PK sample collection was performed in subjects who agreed to blood samplings for the PK assessments of PAN and BTZ. The order of administration of the 3 study treatment components was 1) PAN, 2) Dex, and 3) BTZ.

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: T1/2Predose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h 48h post dose

T1/2: The elimination half-life associated with the terminal slope (Lambda_z) of a semi logarithmic concentration-time curve

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: Lambda_zPredose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h 48h post dose

Lambda_z: The terminal elimination rate constant (h-1)

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: CL/FPredose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h 48h post dose

CL/F: The apparent total body clearance of drug from the plasma

Composite PharmacoKinetics (PK) of Panobinostat and Bortezomib: Vz/FPredose, 0.5h, 1h, 2h, 3h, 4h 8h, 24h 48h post dose

Vz/F: The apparent volume of distribution during terminal phase (associated with Lambda_z)

Overall Survival (OS)up to 30 days after end of study, approx. 4 years

OS is defined as time from first dose of study treatment to death

Time to Response (TTR) Per Investigatorduration of study up to approx. 4 years

TTR is defined as the time from the date of first dose of study treatment to first documented response (PR or nCR or CR) per modified EBMT criteria as assessed by investigator

Time to Progression/Relapse (TTP) Per Investigatorduration of study up to approx. 4 years

TTP is defined as the time from the date of the first dose of study treatment to the date of the first documented disease progression or relapse

Duration of Response (DOR) Per Investigatorduration of study up to approx. 4 years

DOR is defined as the time from date of the first documented CR/nCR or PR to the date of the first documented progression or relapse or death due to MM

Quality of Life (QoL) as Measured by FACT/GOG-Ntx Total ScoreBaseline, Weeks 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, and 156

QoL as measured by Functional Assessment of Cancer Therapy/ Gynecology Oncology Group Neurotoxicity (FACT/GOG-NTX) scale calculated scores and changes from baseline were summarized by visit. The FACT/GOG-Ntx is a measure to assess neurotoxicity from systemic chemotherapy. The recall period for this measure is the past 7 days. FACT/GOG-Ntx Total Score: 0 - 152 (28 + 28 + 24 + 28 + 44 = 152). (FACT-G Physical Well-Being Score: 0 - 28, FACT-G Social/Family Well-Being Score: 0 - 28, FACT-G Emotional Well-Being Score: 0 - 24, FACT-G Functional Well-Being Score: 0 - 28, FACT/GOG-Ntx Neurotoxicity Subscale Score: 0 - 44). 4. The scales are combined. The higher the score, the better the QOL.

Minimal Response Rate (MRR) Per Investigatorafter 24 weeks (8 cycles; cycle = 21 days)

MRR is based on modified EBMT criteria per investigator assessment
