RNA-Based Therapeutic Strategies in Multiple Myeloma: From Molecular Targets to Delivery and Clinical Translation

Year: 2026

Type: article

Abstract: Multiple myeloma (MM) is a challenging hematologic malignancy characterized by clonal plasma cell proliferation, often leading to significant morbidity and mortality worldwide. Despite advances in chemotherapy and CAR-T therapies, MM remains incurable due to tumor heterogeneity, immune evasion, and microenvironment remodeling-exacerbated by toxicities like cytokine release syndrome and myelosuppression. This urgent unmet need demands innovative strategies. In this review, we assess cutting-edge RNA-based therapeutics for MM modulation, drawing on preclinical and clinical evidence on modalities including mRNA vaccines, small interfering RNAs (siRNAs), antisense oligonucleotides (ASOs), and microRNA (miRNA) mimics/inhibitors. We further explore RNA-engineered cell therapies, such as transient CAR-T platforms and lipid nanoparticle-delivered systems targeting the bone marrow niche. By integrating these insights, we underscore RNA technologies' transformative potential to achieve durable remissions, overcome resistance, and reduce costs-paving the way for personalized, safer treatments in refractory MM.
