## TL;DR

This study examines the effectiveness and safety of daratumumab maintenance therapy after stem cell transplantation in newly diagnosed multiple myeloma patients.

## Contribution

The study provides real-world evidence on the efficacy and safety of daratumumab maintenance post-transplant in NDMM patients.

## Key findings

- Daratumumab maintenance increased hematologic and renal remission rates in NDMM patients.
- The main adverse event was grade 3 pneumonia, occurring in 33.33% of patients.
- One-year overall survival rate was 93.33% with only one death unrelated to treatment.

## Abstract

探讨新诊断多发性骨髓瘤（NDMM）患者自体造血干细胞移植（auto-HSCT）后达雷妥尤单抗维持治疗的疗效及安全性。

回顾性分析2022年5月1日至2023年6月30日期间解放军总医院第五医学中心血液病医学部淋巴瘤-浆细胞疾病专科的15例NDMM患者auto-HSCT后接受达雷妥尤单抗维持治疗的临床资料、血液学及肾脏疗效、安全性。

15例患者中男11例，女4例，中位年龄58（41～72）岁；其中13例患者于诱导治疗及auto-HSCT阶段均未使用达雷妥尤单抗，6例伴有肾损害，9例遗传学高危。达雷妥尤单抗维持治疗的中位时间为6（1.5～12）个月，中位输注次数12（6～17）次。15例患者均可评估疗效，达雷妥尤单抗维持治疗使缓解深度增加，血液学严格意义的完全缓解率（sCR）由40％增加至60％；6例伴肾损害患者的肾脏缓解率由16.67％ 提升至33.33％。血液学3级以上不良事件（AE）主要为淋巴细胞减少（26.67％，4/15），非血液学AE主要为输注相关反应（46.67％，7/15）及3级肺炎（33.33％，5/15）。5例（38.46％，5/13）发生肺炎的患者均为达雷妥尤单抗初治者，发生时间在中位输注8（6～10）次，3例肺炎为肺间质改变，甲泼尼龙治疗有效。中位随访时间为12（7～13）个月，1例死亡（与达雷妥尤单抗治疗无关），1年总生存率为93.33％。

达雷妥尤单抗用于NDMM患者auto-HSCT后维持治疗可提高血液学及肾脏缓解率，且不良反应可控。主要的AE是3级肺炎，减少维持治疗期间前8周每周一次给药频次可能使肺炎发生率下降。
