- High-risk SMM is defined here according to the revised Mayo Clinical criteria (2 out of 3 criteria must be fulfilled):
- Bone marrow clonal plasma cells \> 20%
- Serum M protein \> 2.0g/dL
- Serum-free light chain ratio \> 20, measured with "Binding site Kit"
- Early 'SLiM CRAB' multiple myeloma
- Patients must present with only one of the following features
- Bone marrow clonal plasma cells ≥ 60%, or
- Serum FLC ratio ≥ 100 (kappa-LC leading) or ≤ 0.01 (lambda-LC leading), measured with "Binding site Kit", or
- \>1 Focal bone lesion of ≥5mm (not associated with osteolysis, detected by PET-CT or whole-body low-dose CT (WBLDCT))
- Time from diagnosis of high-risk SMM or SLIM CRAB positive, early MM to study enrollment: \<5 years
Exclusion
- ECOG \>3
- Active, symptomatic MM (fulfilling CRAB-criteria)
- Non-secretory MM, extramedullary plasmacytoma, plasma cell leukemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes)
- MGUS
- Hypocalcemia (can be corrected by drug intervention before start of treatment)
- Second malignancy within the past 5 years except:
- Adequately treated basal cell or squamous cell skin cancer
- Carcinoma in situ of the cervix

- Ductal breast carcinoma in situ with full surgical resection (i.e., negative margins)
- Treated medullary or papillary thyroid cancer
- Similar condition with an expectation of \> 95% five-year disease-free survival
- Active infection within the 14 days prior to randomization requiring systemic antibiotics and/or antiviral therapy
- Patients with known active or latent tuberculosis
- Known human immunodeficiency virus (HIV) seropositivity or active hepatitis C or hepatitis B infection (subjects with past hepatitis B virus \[HBV\] infection or resolved HBV infection defined as having a negative HBsAg test and a positive antibody to hepatitis B core antigen \[anti-HBc\] antibody test are eligible; subjects positive for hepatitis C virus \[HCV\] antibody are eligible only if polymerase chain reaction \[PCR\] is negative for HCV RNA.)
- Participation in another interventional study within the 28 days prior to randomization
- Any other clinically significant medical disease or social condition that, in the investigator's opinion, may interfere with protocol adherence or a subject's ability to give informed consent, be compliant with study procedures, or provide accurate information.
- Prior administration of denosumab
- Prior exposure to any experimental or approved anti-myeloma agent
- Use of oral bisphosphonates with a cumulative exposure of more than 1 year (washout period for allowed bisphosphonate exposure 1 month)
- More than 1 previous dose of IV bisphosphonate or teriparatide administration (washout period for allowed bisphosphonate exposure 1 month)
- Prior history or current evidence of osteonecrosis/osteomyelitis of the jaw
- Active dental or jaw condition which requires oral surgery, including tooth extraction
- Subject is pregnant or breastfeeding, or planning to become pregnant within 7 months after the end of treatment
- Female subject of childbearing potential is not willing to use, in combination with her partner, a highly effective and in addition an effective method of contraception during treatment and for 5 months after the end of treatment
- Known sensitivity to denosumab (including all components of the formulation) or any of the products to be administered during the study (eg, mammalian derived products, calcium, or vitamin D)
- Subject is receiving or is less than 30 days since ending other experimental devices or drugs (no marketing authorization for any indication).
- Subject will not be available for follow-up assessment
