  • Definitive increase in the size of existing plasmacytomas or bone lesions;
  • Hypercalcemia (>11 mg/dL);
  • Decrease in hemoglobin of >2 g/dL not related to therapy or other non-myeloma related conditions;
  • Rise in serum creatinine by 2 mg/dL or more from the start of the therapy and attributable to myeloma;
  • Hyperviscosity related to serum protein.
• Increase of 25% from the lowest confirmed response value in one or more of the following criteria:
  • serum M-protein (increase must be at least 0.5 g/dL);
  • urine M-protein (increase must be at least 200 mg/24 hours);
  • the difference between involved and uninvolved free light chain levels (increase must be >10 mg/dL).
• Patients who have started treatment with daratumumab monotherapy or daratumumab combination regimens as second line treatment or beyond within the 1 month prior to enrollment. Daratumumab use will according to the locally approved label.
• Patients who have received prior autologous stem cell transplant and are beyond day +100 are allowed to participate.
