BACKGROUND: The clinical need for treating anemia in aplastic anemia (AA) patients remains unmet. Luspatercept has been shown to be effective in myelodysplastic neoplasms (MDS).
METHODS: Patients who were newly diagnosed with non-transfusion-dependent non-severe AA (NTD-NSAA) were randomly assigned to receive either cyclosporine (CsA) combined with luspatercept or CsA monotherapy at a 1:1 ratio. This study (ClinicalTrials.gov NCT05399732) aimed to compare their treatment responses, safety, disease progression, and outcomes.
RESULTS: In total, 58 patients participated in the final analysis, with 29 receiving CsA+luspatercept and 29 receiving CsA monotherapy. With a median follow-up of 12 months (range: 6-25) and 12 months (range: 7-25), respectively, the overall response rates (ORRs) were 69.0% vs. 37.9% (p = 0.018) at the 3rd month, 79.3% vs. 51.7% (p = 0.027) at the 6th month, and 72.4% vs. 51.7% (p = 0.104) at the end of follow-up. Patients receiving CsA+luspatercept had a shorter time to achieve a positive response than those receiving CsA alone (p = 0.004). A post hoc subgroup analysis based on age (< 60 vs. ≥60 years) showed no significant difference in ORRs for those < 60 years old. However, for patients ≥ 60 years old receiving CsA+luspatercept, a significantly greater ORR was demonstrated at both the 3rd month (p = 0.032) and 6th month (p = 0.046) compared with CsA monotherapy.
CONCLUSIONS: Compared with CsA monotherapy, the combination of CsA and luspatercept resulted in a higher response rate and a shorter time to response for patients with NTD-NSAA, with an acceptable safety profile. The benefit of CsA+luspatercept was most pronounced in older patients.
