Accident – Death – Obituary News : Multiple myeloma (MM) is a prevalent hematologic malignancy, affecting a substantial number of individuals each year. In 2024, it is estimated that nearly 35,780 people will be diagnosed with MM, with men accounting for 19,520 cases and women for 16,260 cases, according to the American Cancer Society. While MM is considered incurable, advancements in innovative therapies have significantly improved treatment outcomes for patients. However, there remains an unmet need among high-risk patients in both newly diagnosed and relapsed settings, prompting the development of emerging treatments like G protein-coupled receptor class C group 5 member D (GPRC5D)-targeted chimeric antigen receptor (CAR) T-cell therapy.

Standard-of-care treatment for MM typically involves a combination of immunomodulatory agents, proteasome inhibitors, dexamethasone, and chemotherapy, followed by autologous stem cell transplantation. Despite the success of these therapies, many patients experience relapse and develop drug resistance. To address this challenge, researchers are exploring advanced therapeutic approaches with different mechanisms of action, such as immunotherapeutic treatments and bispecific antibodies, which offer more targeted and potent treatments for pretreated patients.
One promising innovation in MM treatment is CAR T-cell therapy, a novel immunotherapy that involves modifying a patient’s T cells to target and destroy cancer cells. Clinical trials have shown efficacy in targeting proteins with high expression in MM, including cluster of differentiation 38, B-cell maturation antigen (BCMA), and GPRC5D. GPRC5D is an emerging therapeutic target found on the surface of MM cells, with high expression in approximately 90% of patients.
Recent data from the CC-95266-MM-001 study, presented at the European Hematology Association 2024 Hybrid Congress, demonstrated promising overall response and complete response rates in participants with relapsed/refractory MM who received GPRC5D-targeted CAR T-cell therapy. The study highlighted the potential of this treatment approach in both early and late-line therapy, offering high response rates and improved outcomes for patients.
While GPRC5D-targeted CAR T-cell therapy shows promise in MM treatment, it also presents unique toxicities, such as dysgeusia and weight loss, which can impact patients’ quality of life. Continued research is needed to overcome these challenges and improve treatment response rates. Clinicians are exploring early intervention strategies to address adverse effects and enhance patients’ overall experience with bispecifics and CAR T-cell therapy.

The evolving therapeutic landscape of MM treatment is focused on providing high-risk patients with advanced treatments that offer improved responses, reduced adverse effects, and enhanced quality of life post-treatment. The ongoing phase 2 trial of GPRC5D-targeted CAR T-cell therapy will further assess the efficacy of this innovative approach, with the potential to revolutionize MM treatment for high-risk patients.
In conclusion, the development of GPRC5D-targeted CAR T-cell therapy represents a significant advancement in MM treatment, offering new hope for patients with high-risk disease. Continued research and clinical trials are essential to optimize this therapeutic approach and improve outcomes for individuals living with MM..
