Administration of teclistamab in four patients with multiple myeloma requiring hemodialysis

Objective Relapsed/refractory multiple myeloma (MM) has poor outcomes, especially in heavily pretreated patients. Limited data exists on the use of novel therapies in MM patients with renal dysfunction. This case series describes the successful initiation of teclistamab in four patients with heavily pre-treated MM on hemodialysis (HD).Data Sources The medical records of four adult MM patients on HD who received teclistamab were retrospectively reviewed.Data Summary All patients completed teclistamab step-up dosing and received at least one full dose. HD runs were administered irrespective of teclistamab initiation. Patients tolerated therapy well, with only one patient experiencing grade 1 CRS, which was managed with supportive care.Conclusions Due to the complexity of this patient population, close monitoring and multidisciplinary care are crucial. This approach is essential for effectively managing MM patients with renal dysfunction and for exploring novel treatment options.
