Exclusion criteria
Exclusion criteria: 1. Multiple myeloma, requiring treatment, defined by any of the following: a. Bone lesions (one or more osteolytic lesions on low-dose whole body computed tomography [LDCT], positron-emission tomography with computed tomography [PET-CT] or computed tomography [CT]) b. Hypercalcemia (serum calcium >0.25 mmol/L [>1 mg/dL] higher than ULN or >2.75 mmol/L [>11 mg/dL]) c. Renal insufficiency, preferably determined by creatinine clearance 177 micro mole per litre (µmol/L) d. Anemia, defined as hemoglobin 2 g/dL below lower limit of normal or both; transfusion support or concurrent treatment with erythropoietin stimulating agents is not permitted e. Clonal BMPC percentage =60% f. Serum FLC ratio (involved:uninvolved) =100 (The involved FLC must be =100 mg/L) g. More than 1 focal lesion =5 mm in diameter by magnetic resonance imaging (MRI) 2. Primary systemic (immunoglobulin light chain) amyloidosis (AL) 3. Exposure to any of the following a. Prior exposure to daratumumab or prior exposure to other anti-CD38 therapies b. 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 as indicated for osteoporosis is acceptable. c. 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 d. Ongoing treatment with corticosteroids with a dose >10 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 4. Received treatment 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. 5. Either of the following: a. Known or suspected chronic obstructive pulmonary disease (COPD) with a forced expiratory volume in 1 second (FEV1) <50% of predicted normal b. Moderate or severe persistent asthma within the past 2 years or currently has uncontrolled asthma of any classification (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study) 6. Any of the following: a. Known to be seropositive for human immunodeficiency virus (HIV) b. Seropositive for hepatitis B (defined by a positive test for hepatitis B surface antigen [HBsAg]). Local testing and results of hepatitis B serology (Includes HBsAg, anti-HBs, and anti-HBc) is required for all patients prior to randomization when this amendment 3 is implemented. Subjects with resolved infection (ie, subjects 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) DNA levels. Those who are PCR positive will be excluded. EXCEPTION: Subjects with serologic findings suggestive of HBV vaccination (Anti-HBs positivity as the only serologic marker) A
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The main objective of this study is to determine whether treatment with daratumumab administered subcutaneously (SC) prolongs progression-free survival (PFS) compared with active monitoring in subjects with high-risk smoldering multiple myeloma (SMM).;Secondary Objective: -To demonstrate additional clinical benefit (ORR, duration of response, OS, etc) for subjects with high-risk SMM treated with daratumumab compared with active monitoring - To assess the safety profile of daratumumab in subjects with high-risk SMM - To assess the clinical characteristics of symptomatic MM following progression of disease after therapy with daratumumab - To evaluate the PK and immunogenicity of daratumumab administered SC in subjects with high-risk SMM - To evaluate the immunogenicity of rHuPH20 when administered in combination with daratumumab SC in subjects with high-risk SMM - To evaluate the effect of treatment with daratumumab on health-related quality of life (HRQoL);Primary end point(s): Progression-free survival (PFS), defined as the time from the date of randomization to the date of initial documented progression to MM according to the international myeloma working group (IMWG) diagnostic criteria for MM or the date of death, whichever occurs first;Timepoint(s) of evaluation of this end point: Every 12 weeks until progressive disease | — |
Secondary
