Arm Intervention/treatment
Experimental: GBR 1342
Open-label dose escalation of GBR 1342
Biological: GBR 1342
GBR 1342 will be administered by intravenous (IV) infusion on Day 1 and Day 15 of each 28-day treatment cycle at escalating dose levels

Primary Outcome Measures :
  1. Maximal Tolerated Dose (MTD) of GBR 1342 (Part 1) [ Time Frame: 28 days ]
    MTD will be assessed by detection of number of DLTs (dose limiting toxicities) during the first 28 days after the first administration of study drug (i.e. Cycle 1) in each cohort

  2. Objective response to GBR 1342 according to International Myeloma Working Group (IMWG) response criteria (Part 2) [ Time Frame: 28 days ]
  3. Frequency and severity of AEs according to CTCAEv4.03 [ Time Frame: 28 days ]
    The relationship of the dose of GBR 1342 with frequency and severity of AEs will be assessed based on CTCAEv4.03.

Secondary Outcome Measures :
  1. Maximum serum concentration (Cmax) of GBR 1342 [ Time Frame: 28 days ]
  2. Area under the serum concentration time curve from zero to time t (AUC0-t) of GBR 1342 [ Time Frame: 28 days ]
  3. Immunogenicity of GBR 1342 by anti-drug antibody (ADA) formation assessed from baseline until end of treatment [ Time Frame: 28 days ]
  4. Anti-tumor activity of GBR 1342 (Disease control rate) [ Time Frame: 28 days ]
