Brief summary

In a randomized, controlled clinical trial, the efficacy and safety of rodsipil combined with cyclosporine versus cyclosporine alone in the treatment of newly diagnosed non-transfusion-dependent NSAA were compared.

Detailed description

Conduct a comparative evaluation of the effectiveness and safety of Luspatercept combined with cyclosporine versus cyclosporine monotherapy in the treatment of newly diagnosed non-transfusion-dependent non-severe aplastic anemia (NSAA). Patients were randomized in a 1:1 ratio and assigned to one of two groups: Group A, Luspatercept combined with cyclosporine: received Luspatercept (1.0 mg/kg, subcutaneous injection every 3 weeks), cyclosporine (3-5mg/kg/day), adjusted based on hematological parameters, for at least 6 months to assess efficacy. Effective patients continued to receive cyclosporine treatment for at least 1.5 years, with a gradual reduction in dosage; Group B, cyclosporine: received 3-5mg/kg/day, adjusted based on hematological parameters, for at least 6 months to assess efficacy, with effective patients continuing to receive cyclosporine treatment for at least 1.5 years, with a gradual reduction in dosage. Hgb below 60g/L was allowed, or in emergency conditions, blood transfusion was allowed. Platelets below 20×10\^9/L or with obvious bleeding tendency were allowed to receive platelet transfusion. If neutrophil count was below 1.0×10\^9/L, G-CSF was allowed until neutrophil count recovered to above 1.0×10\^9/L. Symptoms, treatment-related adverse events, signs, blood transfusion volume, and laboratory tests (including reticulocyte count) were recorded at least every 3 months for the first 3 months, and every 6 months thereafter until 6 months, and bone marrow aspiration, biopsy, and chromosome examination were performed at least every 6 months to observe efficacy and safety.

Inclusion criteria

1. Age ≥ 18 years 2. Hemoglobin level of 6-10 g/dL 3. Definition of NSAA: Patients with AA diagnosis but not SAA or VSAA diagnosis (at least two of the following conditions can be diagnosed as AA: (i) Hemoglobin \< 100 g/L; (ii) Platelet count \< 50×10\^9/L; (iii) Neutrophil count \< 1.5×10\^9/L. SAA diagnosis criteria include less than 25% (or 25-50%, but residual hematopoietic cells \< 30%) of bone marrow cells, plus at least two of the following conditions: (i) Neutrophil count \< 0.5×10\^9/L; (ii) Platelet count \< 20×10\^9/L; (iii) Retroperitoneal lymph node count \< 20×10\^9/L. VSAA meets the criteria for SAA, but with neutrophil count \< 0.2×10\^9/L. (British guidelines, 2015)) 4. No active infection 5. No other concurrent neoplasms (except in situ carcinoma) 6.
