Brief Title  ICMJE A Study of Subcutaneous Daratumumab Versus Active Monitoring in Participants With High-Risk Smoldering Multiple Myeloma
Official Title  ICMJE A Phase 3 Randomized, Multicenter Study of Subcutaneous Daratumumab Versus Active Monitoring in Subjects With High-Risk Smoldering Multiple Myeloma
Brief Summary The primary objective of this study is to determine whether treatment with daratumumab administered subcutaneously (SC) prolongs progression-free survival (PFS) compared with active monitoring in participants with high-risk smoldering multiple myeloma (SMM).
Detailed Description This study consists of 3 phases: Screening Phase (up to 35 days), an Active Monitoring Phase or a Treatment Phase of 39 cycles or 36 months (whichever occurs first), and a Follow-up Phase which will continue until death, lost to follow-up, consent withdrawal, or study end (approximately 8 years after the first participant is randomized), whichever occurs first. Active monitoring cycles and treatment cycles are 4 weeks in length. For all participants, disease evaluations will be performed every 12 weeks until confirmed progressive disease (PD). After PD, survival is to be followed at least every 6 months, until the end of the study. Participants will undergo tumor assessments, pharmacokinetics, biomarkers and safety evaluations (adverse events, laboratory tests, vital sign measurements, physical examinations, Eastern Cooperative Oncology Group [ECOG] performance status) over the time.

    1. Bone lesions (1 or more osteolytic lesions on low-dose whole body computed tomography [LDCT], positron-emission tomography with computed tomography [PET-CT] or CT). Participants who have benign/post-traumatic bone lesions visible on screening images as well as previous imaging, may be considered for inclusion. Details (diagnosis, location, duration) on benign/post-traumatic pre-existing bone lesions that can be seen on the screening images (example [eg.], old fractures) and were also present on previous imaging are to be reported in the case report form (CRF)
    2. Hypercalcemia (serum calcium greater than [>]0.25 millimoles per liter [mmol/L] [>1 milligram per deciliter {mg/dL}] higher than upper limit of normal [ULN] or >2.75 mmol/L [>11 mg/dL]). Participants who have clinically stable hypercalcemia attributable to a disease other than multiple myeloma (eg, hyperparathyroidism) may be considered for inclusion after a case by case review by the medical monitor
    3. Renal insufficiency, preferably determined by creatinine clearance less than (<)40 milliliter per minute (mL/min) measured or estimated using the Modification of Diet in Renal Disease (MDRD), or serum creatinine >177 micromole per liter (μmol/L). Participants who have clinically stable renal insufficiency attributable to a disease other than multiple myeloma (eg, glomerulonephritis) may be considered for inclusion after a case by case review by the medical monitor
    4. Anemia, defined as hemoglobin <10 gram per deciliter (g/dL) or >2 g/dL below lower limit of normal or both; transfusion support or concurrent treatment with erythropoietin stimulating agents is not permitted. Participants who have clinically stable anemia attributable to a disease other than multiple myeloma (eg, thalassemia, vitamin B12 deficiency, iron deficiency) may be considered for inclusion after a case by case review by the medical monitor
    5. Clonal BMPC percentage >=60%
    6. Serum FLC ratio (involved:uninvolved) >=100 (the involved FLC must be >=100 mg/L)
    7. More than 1 focal lesion >=5 millimeter (mm) in diameter by magnetic resonance imaging (MRI)
  • Primary systemic amyloid light-chain (AL) (immunoglobulin light chain) amyloidosis
  • Exposure to any of the following:

    1. Prior exposure to daratumumab or prior exposure to other anti-Cluster of Differentiation 38 (anti-CD38) therapies
    2. Prior exposure to approved or investigational treatments for SMM or MM (including but not limited to conventional chemotherapies, immunomodulatory agent [IMiDs], or proteasome inhibitor [PIs]). Stable standard dosing of bisphosphonate and denosumab as indicated for osteoporosis is acceptable
    3. Exposure to investigational drug (including investigational vaccines) or invasive investigational medical device for any indication within 4 weeks or 5 half-lives, whichever is longer, before Cycle 1, Day 1
    4. Ongoing treatment with corticosteroids with a dose >10 milligram (mg) prednisone or equivalent per day at the time of randomization; or >280 mg cumulative prednisone dose or equivalent for any 4-week period in the year prior to randomization
    5. Ongoing treatment with other monoclonal antibodies (eg, infliximab, rituximab), immunomodulators (eg, abatacept, methotrexate, azathioprine, cyclosporine) or other treatments that are likely to interfere with the study procedures or results
  • Received treatment (chemotherapy, surgery, et cetera [etc]) for a malignancy (other than SMM) within 3 years before the date of randomization (exceptions are squamous and basal cell carcinomas of the skin, carcinoma in situ of the cervix or breast, or other non-invasive lesion), which is considered cured with minimal risk of recurrence within 3 years
  • Medical or psychiatric condition or disease (for example, active systemic disease [including presence of auto-antibodies], uncontrolled diabetes) that is likely to interfere with the study procedures or results, or that in the opinion of the investigator, would constitute a hazard for participating in this study
  • Known allergies, hypersensitivity, or intolerance to corticosteroids, monoclonal antibodies, hyaluronidase, or other human proteins, or their excipients, or known sensitivity to mammalian-derived products (including dairy allergy)
