• Be informed and voluntarily sign the Informed Consent Form (ICF).
• Age between 18 and 75 years (inclusive).
• Have measurable disease meeting at least one of the following criteria: Serum M-protein ≥1 g/dL (>10 g/L) as detected by serum protein electrophoresis (SPEP), or quantifiable IgA or IgD levels for IgA or IgD-type myeloma; Urine M-protein ≥200 mg/24 hours; In cases where serum and urine M-protein do not meet the above thresholds, an abnormal free light chain (FLC) ratio (normal range: 0.26 to 1.65) and involved serum FLC ≥100 mg/L.
