Addition of Daratumumab to Combination of Bortezomib and Dexamethasone in Participants with Relapsed or Refractory Multiple Myeloma


About this study

The purpose of this study is to assess the effects of administration of daratumumab when combined with VELCADE (bortezomib) and dexamethasone compared with bortezomib and dexamethasone alone, for participants with relapsed or refractory multiple myeloma.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Subject must be at least 18 years of age.
  • Subject must have had documented multiple myeloma as defined by the criteria below:
    • Monoclonal plasma cells in the bone marrow ≥ 10% at some point in their disease history, or presence of a biopsy-proven plasmacytoma.
  • Measurable disease at Screening as defined by any of the following:
    • IgG multiple myeloma: Serum monoclonal paraprotein (M-protein) level ≥ 1.0 g/dL or urine M-protein level ≥ 200 mg/24 hours; or IgA, IgD, IgE, IgM multiple myeloma: serum M-protein level ≥ 0.5 g/dL or urine M-protein level ≥ 200 mg/24 hours; or Light chain multiple myeloma without measurable disease in the serum or the urine:
    • Serum immunoglobulin free light chain ≥ 10 mg/dL and abnormal serum immunoglobulin kappa lambda free light chain ratio.
  • Subject must have received at least 1 prior line of therapy for multiple myeloma.
    • NOTE: A "line of therapy" is defined as 1 or more cycles of a planned treatment program.
  • Subject must have documented evidence of progressive disease (PD) based on investigator’s determination of response by the IMWG criteria on or after their last regimen.
  • Subject must have achieved a response (partial response [PR] or better based on investigator’s determination of response by the IMWG criteria) to at least 1 prior regimen in the past.
  • Subject must have an ECOG Performance Status score of 0, 1, or 2.
  • For subjects experiencing toxicities resulting from previous therapy (including peripheral neuropathy), the toxicities must be resolved or stabilized to ≤ Grade 1.
  • Women of childbearing potential must commit to either abstain continuously from heterosexual sexual intercourse or to use 2 methods of reliable birth control simultaneously.
  • This includes one highly effective form of contraception (tubal ligation, intrauterine device [IUD], hormonal [birth control pills, injections, hormonal patches, vaginal rings or implants] or partner’s vasectomy) and one additional effective contraceptive method (male latex or synthetic condom, diaphragm, or cervical cap). Contraception must begin 4 weeks prior to dosing. Reliable contraception is indicated even where there has been a history of infertility, unless due to hysterectomy.

  • Subject has known meningeal involvement of multiple myeloma.
  • Criterion modified per amendment INT-1.
  • Subject has peripheral neuropathy or neuropathic pain Grade 2 or higher, as defined by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCICTCAE) most recent version.
  • Subject has either of the following:
    • Known chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) <50% of predicted normal. Note that FEV1 testing is required for subjects suspected of having COPD and subjects must be excluded if FEV1 <50% of predicted normal;
    • Known moderate or severe persistent asthma, or a history of asthma within the last 2 years (see Attachment 8), or currently has uncontrolled asthma of any classification.
      • (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed to participate in the study).
  • Subject is known to be seropositive for human immunodeficiency virus (HIV) or known to have hepatitis B surface antigen positivity, or known to have a history of hepatitis C.

  • Subject is known or suspected of not being able to comply with the study protocol (eg, because of alcoholism, drug dependency, or psychological disorder) or the subject has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subject (e.g., compromise their well-being) or that could prevent, limit, or confound the protocol-specified assessments.
  • Subject is a woman who is pregnant or breastfeeding or planning to become pregnant while enrolled in this study or within 3 months after the last dose of study drug.
  • Subject has received an investigational drug (including investigational vaccines) or used an invasive investigational medical device within 4 weeks before randomization (except for investigational anti-myeloma agents, which cannot be taken within 2 weeks prior to randomization).
  • Subject has had major surgery within 2 weeks before randomization, or has not fully recovered from an earlier surgery, or has surgery planned during the time the subject is expected to participate in the study or within 2 weeks after the last dose of study drug administration. Note: subjects with planned surgical procedures to be conducted under local anesthesia may participate. Kyphoplasty or vertebroplasty are not considered major surgery.
    • NOTE: Investigators should ensure that all study enrollment criteria have been met at screening. If a subject's status changes (including laboratory results or receipt of additional medical records) after screening but before the first dose of study treatment is given such that he or she no longer meets all eligibility criteria, then the subject should be excluded from participation in the study.
  • Source Documentation, describes the required documentation to support meeting the enrollment criteria. Subjects who fail to meet the inclusion and exclusion criteria (i.e., screen failures) may be rescreened if their condition changes. Rescreening must be discussed with and approved by the sponsor on a case-by-case basis. Subjects who are determined to be eligible for rescreening must sign a new ICF and will then be assigned a new Screening number.
