Daratumumab has revolutionized the treatment landscape for multiple myeloma, a challenging blood cancer, by targeting the CD38 glycoprotein on malignant cells. Clinical trials underscore its efficacy, particularly when combined with other therapies, enhancing patient outcomes and progression-free survival. As research progresses, daratumumab’s role in transforming standard care practices continues to expand, offering renewed hope for patients.
Understanding Daratumumab in Multiple Myeloma Treatment
Daratumumab has emerged as a groundbreaking treatment in the management of multiple myeloma, a type of blood cancer characterized by the proliferation of malignant plasma cells. This monoclonal antibody targets the CD38 glycoprotein on the surface of myeloma cells, enhancing their destruction through increased cytotoxicity and modulation of immune responses (source). The introduction of daratumumab into treatment regimens has significantly improved patient outcomes, offering new hope for those diagnosed with this challenging disease.
Clinical Trials and Efficacy
Several clinical trials have demonstrated the efficacy of daratumumab in treating multiple myeloma. The AURIGA study highlighted that daratumumab, when combined with lenalidomide (D-R), significantly improved minimal residual disease (MRD)-negative conversion rates and reduced the risk of disease progression or death by 47% compared to lenalidomide alone in patients with newly diagnosed multiple myeloma (source). Similarly, the PERSEUS trial showed that adding daratumumab to the standard treatment regimen improved progression-free survival, with 84% of patients remaining alive and free of cancer progression after four years (source).
Administration and Safety
Daratumumab can be administered intravenously or subcutaneously, with the latter being preferred due to fewer adverse reactions and reduced time burden for patients. The PERSEUS trial utilized subcutaneous administration, which has become the preferred method since 2020 (source). While daratumumab is associated with some side effects, such as infections and neutropenia, fewer patients in the daratumumab group discontinued treatment due to side effects compared to those receiving standard treatment alone.
Combination Therapies and Future Directions
The potential of daratumumab is further enhanced when used in combination with other therapies. The MajesTEC-3 study demonstrated that combining TECVAYLI® (teclistamab) with DARZALEX® subcutaneous (daratumumab SC) for treating relapsed/refractory multiple myeloma (RRMM) significantly reduced the risk of disease progression or death compared to standard regimens (source). This combination therapy offers a steroid-sparing regimen suitable for outpatient administration, potentially changing the standard of care for RRMM.
