Abstract

Relapsed and refractory multiple myeloma remains a therapeutic challenge, especially in patients who have been exposed to multiple prior lines of therapy. Bispecific antibodies targeting BCMA, such as teclistamab, have represented an advance by redirecting T cells against tumor plasma cells, with immediate availability compared to cell therapies. This study describes the real-world experiences of two patients with heavily pretreated multiple myeloma and high-risk cytogenetics, along with relevant comorbidities.

Both received teclistamab according to the standard regimen. Patient 1 showed a significant metabolic response on PET-CT, with a reduction in bone and extramedullary lesions, developing grade 1 cytokine release syndrome and respiratory infections managed with support and temporary treatment adjustments. Patient 2 maintained prolonged clinical stability, presenting neutropenia and digestive infection as the main complications. Both developed hypogammaglobulinemia requiring intravenous immunoglobulins.

Follow-up from the hospital pharmacy allowed for the optimization of safety and therapeutic continuity through close monitoring and early management of toxicities, confirming the efficacy and manageability of teclistamab in real-world clinical practice.
