Brief Summary:
This study will look at the safety and tolerability of the new drug MLN9708 in combination with the existing drugs panobinostat and dexamethasone among patients with relapsed or refractory multiple myeloma. This study will also look at the response and clinical benefit of the treatment and the progression-free survival and overall survival of study participants.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Kahler Disease Plasma-Cell Myeloma Myelomatosis Drug: Panobinostat Drug: Dexamethasone Drug: MLN9708 Phase 1 Phase 2

Detailed Description:

The primary objective of this study is to define the tolerability and safety of MLN9708 (ixazomib) administered on a day 1,8,15 every 28 day schedule up to 4mg in combination with fixed doses of panobinostat and dexamethasone in patients with relapsed or refractory myeloma.

The secondary objectives of this study are to assess response and clinical benefit response rates according to international uniform response criteria and adapted EBMT criteria, respectively. And to assess progression-free survival (PFS) and overall survival (OS).

Primary Outcome Measures :
  1. Number of Participants With Dose Limiting Toxicity According to CTCAE Version 4.03 [ Time Frame: at 28 days from start of treatment ]
    Number of Participants with Dose Limiting Toxicity of MLN9708 (lxazomib) according to CTCAE version 4.03


Secondary Outcome Measures :
  1. Response to Combination Therapy (Panobinostat, Dexamethasone, MLN9708) [ Time Frame: 4 months (102 days) ]
    Response to intervention as measured by international uniform response criteria and clinical benefit response according to modified EBMT response criteria, comparing myeloma panels obtained at the beginning of each cycle that include SPEP, 24 h UPEP, serum and urine IFEs, and serum free light chains to results at screening. In addition a baseline bone marrow exam and skeletal survey will be obtained and repeated as clinically indicated and for assessment of complete remission (bone marrow)

  2. Progression-free Survival [ Time Frame: 1 year from start of treatment ]

    Progression-free survival will be the number of days from study entry to progression or death of any cause, whichever comes first.

    Progression-free survival is survival with absence of progressive disease, defined by

    • An increase of 25% from lowest response value in any one or more of the following:

      • Serum M-component (absolute increase must be >0.5 g/100 ml) *
      • Urine M-component (absolute increase must be >200mg per 24 h)
      • Only in patients without measurable serum and urine M-protein levels: the difference between involved and uninvolved FLC levels (absolute increase must be >100 mg/l)
      • Bone marrow plasma cell percentage (absolute % must be >10%)
    • And / or:

      • Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas
      • Development of hypercalcemia (corrected serum calcium >11.5 mg/100 ml) that can be attributed solely to the plasma cell proliferative disorder

  3. Overall Survival [ Time Frame: up to 3 years from start of treatment ]
    Overall survival for all will be the number of months from study entry to death from any cause.
