This multicenter, open-label, dose-escalating study will assess the safety and efficacy of DFRF4539A in patients with relapsed or refractory multiple myeloma. Cohorts of patients will receive multiple ascending doses of intravenous DFRF4539A every 3 weeks or weekly. Patients exhibiting acceptable safety and evidence of clinical benefit may receive DFRF4539A for up to 17 cycles. Anticipated time on study treatment is 1 year or until disease progression or unacceptable toxicity occurs.

Primary Outcome Measures:
  • Safety: Incidence of adverse events [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Safety: Maximum tolerated dose/dose-limiting toxicities [ Time Frame: approximately 1.5 years ] [ Designated as safety issue: No ]
  • Recommended Phase II dose for every-3-week or weekly administration of DFRF4539A [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Immunogenicity: Serum antitherapeutic antibody levels [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Pharmacokinetics: Area under the concentration - time curve (AUC) [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Objective response, tumor assessments according to International Myeloma Working Group (IMWG) Uniform Response Criteria and/or European Bone Marrow Transplant (EBMT) Criteria [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Duration of objective response, defined as time from first documented objective response to progression or death of any cause [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
  • Progression-free survival, defined as time from first study treatment (Cycle 1, Day 1) to disease progression or death during study or within 30 days after last dose of study drug, whichever occurs first [ Time Frame: approximately 3.5 years ] [ Designated as safety issue: No ]
