复发/难治性多发性骨髓瘤精准治疗的靶点选择：最新进展

According to the guidelines, the primary treatment for multiple myeloma is still based on drugs such as carfilzomib, lenalidomide, or daratumumab.

However, patients with relapsed/refractory multiple myeloma (RRMM) may be insensitive or develop resistance to the above therapeutic medications.

Thus, formulating standardized and rational treatment regimens for such patients remains an area for consideration. Multidrug combinations are available for the therapy of patients with relapsed/refractory multiple myeloma to improve their clinical outcome and prevent the occurrence of multidrug resistance. For instance, combination therapy with immunomodulators, proteasome inhibitors, and CD38 monoclonal antibodies.

With the development of genomics and molecular diagnostic technologies, RRMM has entered the era of precision therapy. Targeted immunotherapeutic drugs such as monoclonal antibodies, bispecific antibodies, antibody-drug conjugates (ADCs), and chimeric antigen receptor-T (CAR-T) cells have shown promising clinical response rates and favorable safety profiles in several clinical and experimental studies. These cutting-edge medicinal treatments may provide new hope for a cure for RRMM.

However, the choice of treatment regimen still needs to adhere to the principle of individualization. Generally, we recommend treatment with drugs of a new generation or novel mechanism of action for patients with RRMM who are first relapsed, such as next-generation proteasome inhibitors, next-generation immunomodulators, and CD38-based monoclonal antibody regimens. For multiple relapsed RRMM, we recommend choosing a combination regimen or participating in relevant clinical trials.

Additionally, monoclonal antibodies have become the standard of care for patients with RRMM. With the introduction of CAR-T therapy, ADCs, and bispecific antibodies, RRMM patients are expected to achieve deep remissions and long-term survival again.
