Data from two randomized pivotal, phase 3 trials evaluating the combination of lenalidomide and dexamethasone in relapsed/refractory multiple myeloma (RRMM) were pooled to characterize the subset of patients who achieved long-term benefit of therapy (progression-free survival ⩾3 years). Patients with long-term benefit of therapy (n=45) had a median duration of treatment of 48.1 months and a response rate of 100%. Humoral improvement (uninvolved immunoglobulin A) was more common in patients with long-term benefit of therapy (79% vs 55%; P=0.002). Significant predictors of long-term benefit of therapy in multivariate analysis were age<65 years (P=0.03), β2-microglobulin <2.5 mg/l (P=0.002) and fewer prior therapies (P=0.002). The exposure-adjusted incidence rate (EAIR) of grade 3–4 neutropenia was lower in patients with long-term benefit of therapy (13.9 vs 38.2 per 100 patient-years). The EAIR for invasive second primary malignancy was the same in patients with long-term benefit of therapy and other patients (1.7 per 100 patient-years). These findings indicate that patients with RRMM can experience long-term benefit with lenalidomide and dexamethasone treatment with manageable side effects.
两项评估来那度胺与地塞米松联合治疗复发/难治性多发性骨髓瘤(RRMM)的三期随机关键试验数据被合并分析,以明确获得长期治疗获益(无进展生存期≥3年)的患者亚组特征。获得长期治疗获益的患者(n=45)中位治疗时间为48.1个月,缓解率达到100%。其中体液免疫指标(非受累免疫球蛋白A)改善更常见(79% vs 55%;P=0.002)。多变量分析显示,长期治疗获益的显著预测因素包括年龄<65岁(P=0.03)、β2-微球蛋白<2.5 mg/l(P=0.002)及既往治疗线数较少(P=0.002)。长期获益患者的3-4级中性粒细胞减少症暴露校正发生率较低(每100患者年13.9例 vs 38.2例),而侵袭性第二原发恶性肿瘤的暴露校正发生率与其他患者相同(每100患者年1.7例)。这些结果表明,RRMM患者通过来那度胺与地塞米松治疗可获得长期获益,且副作用可控。
