Brief Summary:
A multi-center Phase 1, First-in-Human study conducted in 2 Parts, testing AMG 424 in subjects with relapsed/ refractory multiple myeloma.

Condition or disease Intervention/treatment Phase
Relapsed/ Refractory Multiple Myeloma Drug: AMG 424 Phase 1

Detailed Description:

Part 1 of the study is dose evaluating and aimed at assessing the safety and tolerability of AMG 424 while determining the maximum tolerated dose (MTD) and/or biologically active dose in subjects with relapsed/ refractory multiple myeloma.

Part 2 of the study will further evaluate safety and tolerability of the AMG 424 MTD dose determined in Part 1, in groups of subjects with relapsed/ refractory multiple myeloma that include those with high or low cytogenetic risk.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Multiple myeloma meeting the following criteria:
  • Pathologically-documented diagnosis of multiple myeloma that has relapsed after at least two prior lines of therapy that must include a proteasome inhibitor (PI), immunomodulatory drug (IMiD), and, where approved and available, anti-CD38 therapy in any order OR that is refractory to PI, IMiD, and anti-CD38 therapy.

    ◾Subjects who could not tolerate a PI, IMiDs, or a CD38-directed therapeutic antibody due to unacceptable toxicities are eligible to enroll in the study.

  • Measurable disease as per IMWG response criteria
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of ≤ 2

Exclusion Criteria:

  • Known central nervous system involvement by multiple myeloma
  • Previously received allogeneic stem cell transplant and one or more of the following:

    • received the transplant < 6 months prior to study Day 1
    • received immunosuppressive therapy < 3 months prior to study Day 1
    • any active acute graft versus host disease (GvHD), grade 2- 4, according to the Glucksberg criteria or active chronic GvHD requiring systemic treatment
    • any systemic therapy against GvHD < 2 weeks prior to study Day 1
  • Autologous stem cell transplantation less than 90 days prior to study day 1
  • Multiple myeloma with IgM subtype
  • POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes)
  • Evidence of primary or secondary plasma cell leukemia at the time of screening
  • Waldenstrom's macroglobulinemia
  • Amyloidosis
  • Dexamethasone at cumulative doses of greater than 160 mg or equivalent <3 weeks prior to study Day 1 is not allowed. Use of topical or inhaled steroids is acceptable
  • Anticancer treatment (chemotherapy, IMiD, PI, molecular targeted therapy) < 2 weeks prior to study Day 1
  • Treatment with a therapeutic antibody targeting CD38 < 12 weeks prior to study Day 1
  • Systemic radiation therapy or major surgery < 28 days prior to study Day 1 as well as focal radiotherapy < 14 days prior to study Day 1.
  • Major surgery within 28 days prior to study Day 1
