Abstract
BACKGROUND: As a rapidly developing therapeutic method, targeted therapy plays an important role in the treatment of multiple myeloma. In recent years, mature B cell antigen-targeting therapy has brought new hope for patients with refractory/relapsed disease. While an increasing number of patients with relapse are exposed to this type of drug, changing the therapeutic target may be an effective strategy for patients with relapse/refractory multiple myeloma. OBJECTIVES: The expression of G protein-coupled receptor, class C Group 5 member D (GPRC5D), on the surface of myeloma tumor cells makes it a possible target for relapse/refractory multiple myeloma therapy, and relevant studies are in progress. RESULTS & CONCLUSIONS: The review aims to systematically summarize the current advancements in GPRC5D-targeted therapies for multiple myeloma, thereby providing valuable insights and a foundation for future studies.
