<jats:p>Daratumumab is increasingly incorporated into the standard treatment regimens for patients with plasma cell dyscrasias in Asia, especially with cost-containment measures implemented by various regional health authorities. This analysis aimed to study daratumumab’s tolerability amongst Asian patients. This is a retrospective medical records review of patients who received daratumumab between November 2016 and August 2021 as part of routine clinical care. Sixty-two patients were included in the study: 62.9% had renal impairment, and 27.4% had creatinine clearance (CrCl) <30ml/min. Forty-five patients (72.6%) received daratumumab combination therapy, with a median 1 line of prior therapy. The median duration of follow-up was 12.4 months, and the median duration patients were on treatment with daratumumab was 12.3 months. Twenty-one of 62 (33.9%) patients experienced infusion-related reactions (IRRs) after the first dose of intravenous daratumumab. Seven developed mostly grades 1 and 2 respiratory events, and 14 showed grades 1 and 2 non-respiratory IRRs. Only one patient experienced a grade 1 IRR with the second infusion, with none developing any IRRs in the third or subsequent infusions. Eight (12.9%) patients were affected by hematological adverse events (AEs), mostly grades 2 and 3, with one experiencing grade-4 neutropenia without sepsis. Six (9.7%) patients experienced non-hematological AEs, the commonest being pneumonia and other infections, with one developing Nocardia pneumonia (grade 4) 14 months after the initiation of daratumumab. In conclusion, daratumumab is tolerable amongst Asian patients, including the elderly, and patients with severe renal impairment and chronic lung diseases.</jats:p>
