RESUMEN
Multiple myeloma (MM) remains an incurable malignancy originating from plasma cells. Despite significant advances in treatment, relapses remain inevitable, and novel therapies continue to be needed. Teclistamab-cqyv is a first-in-class, bispecific T-cell engager (BiTE) antibody for the treatment of MM. Teclistamab-cqyv activates the immune system by binding to the cluster of differentiation 3 (CD3) receptor expressed on the surface of T cells and to the B-cell maturation antigen (BCMA) expressed on the surface of MM cells and some healthy B-lineage cells. Teclistamab-cqyv has been shown to be effective in a pivotal trial that demonstrated an overall response rate of more than 60% in heavily pretreated patients. Compared with other BCMA-targeted agents, the side effect profile of teclistamab-cqyv suggests a more tolerable option for elderly patients. Teclistamab-cqyv is now approved by the US Food and Drug Administration (FDA) as monotherapy for the treatment of adult patients with relapsed or refractory MM.
RESUMEN
Epigenetic regulation is a novel approach to cancer treatment. Inhibition of enhancer of zeste homolog 2 (EZH2) is a method to provide targeted epigenetic regulation. Tazemetostat is a first-in-class targeted epigenetic regulator that specifically inhibits EZH2. This new FDA-approved oral treatment received accelerated approval for patients with hematologic and solid malignancies. Tazemetostat was first approved for patients 16 years and older with metastatic or locally advanced epithelioid sarcoma not eligible for complete resection based on the results of an international open-label phase II basket trial. Another open-label multicenter phase II trial led to the approval for patients with relapsed or refractory follicular lymphoma with EZH2 mutation who have received at least two prior systemic therapies or patients who have no satisfactory alternative treatment options. Tazemetostat as an oral EZH2 inhibitor provides a new effective and tolerable treatment option for these patients.
