Daratumumab Retreatment in Participants With Multiple Myeloma Who Have Been Previously Treated With Daratumumab Intravenous (Dara-IV)

Status: Active


The purpose of this study is to compare the efficacy (rate of very good partial response [VGPR] or better as best response as defined by the International Myeloma Working Group [IMWG] criteria) of daratumumab subcutaneous (Dara-SC) in combination with carfilzomib and dexamethasone (Kd) with the efficacy of Kd in participants with relapsed refractory multiple myeloma who were previously exposed to daratumumab intravenous (Dara-IV) to evaluate daratumumab retreatment.

Eligibility Criteria

Inclusion Criteria

  • Evidence of a response (partial response or better based on investigator's determination of response by International Myeloma Working Group [IMWG] criteria) to daratumumab-containing intravenously (IV) therapy with response duration of at least 4 months
  • Relapsed or refractory disease as defined as: a) Relapsed disease is defined as an initial response to previous treatment, followed by confirmed progressive disease (PD) by IMWG criteria greater than (>) 60 days after cessation of treatment. b) Refractory disease is defined as less than (<) 25 percent (%) reduction in M-protein or confirmed PD by IMWG criteria during previous treatment or >60 days after cessation of treatment
  • Received 1 or 2 prior line(s) of treatment of which one contained Dara IV, and completed Dara IV at least 3 months prior to randomization. A single line of therapy may consist of 1 or more agents, and may include induction, hematopoietic stem cell transplantation, and maintenance therapy. Radiotherapy, bisphosphonate, or a single short course of corticosteroids (no more than the equivalent of dexamethasone 40 milligram per day [mg/day] for 4 days) would not be considered prior lines of therapy
  • Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0, 1, or 2
  • Women of childbearing potential must have a negative urine or serum pregnancy test at screening within 14 days prior to randomization

Exclusion Criteria

  • Previous treatment with daratumumab within the last 3 months prior to randomization
  • Discontinuation of Dara IV due to a daratumumab-related adverse event (AE)
  • History of malignancy (other than multiple myeloma) unless all treatment of that malignancy was completed at least 2 years before consent and the patient has no evidence of disease. Further exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or breast, or other non-invasive lesion, that in the opinion of the investigator, with concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence within 3 years
  • Allergies, hypersensitivity, or intolerance to daratumumab, hyaluronidase, monoclonal antibodies (mAbs), human proteins, or their excipients, or known sensitivity to mammalian-derived products. Known history of allergy to Captisol (a cyclodextrin derivative used to solubilize carfilzomib)
  • Participant is: a) Known to be seropositive for human immunodeficiency virus. b) Seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen [HBsAg]). Participants with resolved infection (example: participants who are HBsAg negative but positive for antibodies to hepatitis B core antigen [anti-HBc] and/or antibodies to hepatitis B surface antigen [anti-HBs]) must be screened using real-time polymerase chain reaction (PCR) measurement of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) levels. Those who are PCR positive will be excluded. c) Known to be seropositive for hepatitis C (except in the setting of a sustained virologic response [SVR], defined as aviremia at least 12 weeks after completion of antiviral therapy)

Trial Objectives and Outline

For relapsed or refractory multiple myeloma, the treatment is determined on an individual basis. Common standard of care regimens use either a proteasome inhibitor (PI) or an immunomodulatory agent (IMiD) in combination with dexamethasone with or without a monoclonal antibody (mAb) such as daratumumab. After relapse from PIs or IMiDs, patients are often retreated with drugs that have same mechanism of action to which they have been sensitive. The disease becomes refractory and all effective treatment options are exhausted. Daratumumab is a human IgG1 mAb that binds with high affinity to unique epitope on cluster of differentiation 38 (CD38) and attacks tumor cells that overexpress CD38. Study is to determine the efficacy of Dara-SC in combination with carfilzomib and dexamethasone (DKd) in adult participants with relapsed refractory MM who had 1 or 2 prior line(s) of treatment including a line containing Dara-IV to evaluate daratumumab retreatment. The MM treatment is determined on an individual basis where patient's age, prior therapy, bone marrow function, co-morbidities, patient preference and time to relapse are considered. Common standard of care regimens use either PI or an IMiD in combination with dexamethasone with or without a mAb. It is a targeted immunotherapy that attacks tumor cells that overexpress CD38, a transmembrane glycoprotein, in a variety of hematological malignancies including multiple myeloma. The study will be conducted in 3 phases: Screening (28 days), Treatment, and Follow-Up. Assessments like chest X-ray, spirometry test, electrocardiogram (ECG), will be performed during Screening phase. During the Treatment Phase, participants will be randomized to receive Kd or DKd. Efficacy assessments like bone marrow examination will be performed. Follow-up will continue until the end of study.
