多发性骨髓瘤的“现货型”免疫治疗

Over the past couple of decades, the life expectancy of patients with multiple myeloma (MM) has progressively increased, however, the disease per se remains incurable. This has resulted in a subset of the patient population who have progressed despite multiple standard treatment options but remain amenable for novel therapies to achieve durable remission. With the discovery of the role of B-Cell Maturation Antigen (BCMA) in the pathogenesis of MM, strategies targeting the BCMA have been the focus of many treatment modalities in development. Although autologous CAR-T cell therapy has shown an overall efficacy of >80% across various phases of studies, it has its own set of limitations and challenges.

There is now an increasing focus on identifying novel therapeutic targets for multiple myeloma and developing "off-the-shelf" immunotherapeutic approaches for treatment of MM. This review discusses and highlights the emerging data from various ongoing trials on "off-the-shelf" approaches like antibody-drug conjugates, bispecific antibodies, and allogeneic cellular therapies demonstrating feasibility, acceptable safety, and promising preliminary efficacy.

Ongoing and future efforts will need to focus on comparative effectiveness of these different approaches, possible combination strategies, and ensuring equitable and affordable access to these therapies globally.
