Inclusion Criteria:

• Must be able to comply with the protocol requirements
• Must voluntary sign the informed consent before performance of any study-related procedure not part of normal medical care
• Age ≥ 18 years

• Patient recently diagnosed with smoldering Multiple Myeloma with high risk of progression to symptomatic Multiple Myeloma defined as follows:

  • Bone Marrow infiltration ≥ 10% CPs and M component Ig G ≥ 3 g/dl or Ig A ≥ 2 g/dl or Bence Jones Protein > 1 g/dl and absence of: hollowed out areas of bone, Hypercalcemia (Calcium-serum < 11.5 mg/dl), Renal Failure (creatinine < 2 mg/dl) and anaemia (Hb > 10 g/dl or at least 2g/dl under normal value.

  • Alternatively, patients with Bone Marrow infiltration with CPs ≥ 10 %, or Ig G ≥ 3 g/dl or Ig A ≥ 2 g/dl or Bence Jones Protein > 1 g/24h (but not the two of them together) and always without: lytic lesions, Hypercalcaemia, Renal Failure and Anaemia could be admitted with the following additional criteria:
