  2. Topics  When to treat? Smoldering vs Symptomatic  Choice of Induction regimen  Role of HDT  Role of consolidation/maintenance

  3. Criteria for Diagnosis of Myeloma SMM Active MM MGUS ≥ 3 g M spike • ≥ 10% plasma cells • • < 3 g M spike ≥ 10% plasma cells • < 10% plasma cells • • M spike + AND AND Anemia, bone lesions, No anemia, bone lesions, high calcium, or normal calcium, and abnormal kidney function kidney function MGUS = monoclonal gammopathy of unknown significance; SMM = smoldering multiple myeloma. Kyle et al, 2009.

  4. Not all Smoldering patients are the same 27% will convert in 15 years Roughly 2% per year Kyle R et al. N Engl J Med 2007;356:2582-2590

  5. Free Light is Useful for Risk Assessment in AMM Dispenzeri et al Blood 2008

  6. Updated IMWG Criteria for Diagnosis of Multiple Myeloma MGUS Smoldering Myeloma Multiple Myeloma • M- protein ≥ 3 g/dL (serum) • M-protein < 3 g/dL • Underlying plasma cell or ≥ 500 mg/24 hrs (urine) proliferative disorder • Clonal plasma cells in BM AND < 10% • Clonal plasma cells in BM ≥ 10% - 60% • No myeloma defining events • 1 or more myeloma defining • No myeloma defining events events including either:  ≥ 1 CRAB feature(s) OR  ≥ 1 Biomarker Driven C : Calcium elevation (> 11 mg/dL or > 1 mg/dL higher than ULN) R: Renal insufficiency (creatinine clearance < 40 mL/min or serum creatinine > 2 mg/dL) A: Anemia (Hb < 10 g/dL or 2 g/dL < normal) B : Bone disease (≥ 1 lytic lesions on skeletal radiography, CT, or PET -CT) Biomarker driven (1) Sixty- percent (≥60%) clonal PCs by BM; (2) serum free Li ght chain ratio involved:uninvolved ≥100; (3) >1 focal lesion detected by MRI Rajkumar SV, et al.

  14. CR and ≥ VGPR rates in high risk subgroups of patients Does it matter which 3 drugs are used? P< 0.001 P< 0.001 P= 0.155 P< 0.001 Cavo et al, Leukemia 2016 Responses to both VTD and VCD were reassessed centrally

  15. Randomized Trial VTD vs VCD Shows superiority of IMID/PI VCD is no longer a reasonable induction choice Moreau et al, Blood 2016

  16. RVD is better than VCD Compass trial, IA9

  33. Safety (excluding ASCT, and maintenance) AEs leading to exclusion - During induction : 1 rash - Late consolidation: 1 rash - Before maintenance: 1 thrombocytopenia 12 cases of non-hematologic grade 3-4 toxicities were reported: -infections (8 cases), -abdominal pain (2), -atrial fibrillation (1), -thrombosis (1) No cardiac failure, no ischemic heart disease, no renal impairment No grade 3-4 peripheral neuropathy
