Final Thoughts: Advancing Multiple Myeloma Care With Bispecific Antibodies
An expert discusses the evolving role of bispecific antibodies in multiple myeloma, highlighting their off-the-shelf availability, immune-targeting mechanism, and growing potential in relapsed and frontline settings, while emphasizing the need for proactive toxicity management, personalized supportive care, and strategic integration into broader treatment plans.
Bispecific antibodies represent a promising advancement in the treatment landscape of multiple myeloma, especially for patients with relapsed or refractory disease. These therapies are engineered to simultaneously bind to a tumor-associated antigen on myeloma cells and a CD3 receptor on T cells, effectively redirecting the patient’s immune system to target and eliminate malignant plasma cells. Unlike individualized treatments such as CAR T-cell therapy, bispecific antibodies are available off-the-shelf, allowing for faster initiation of treatment. Their ease of administration and growing body of clinical data make them an increasingly important option for patients with few remaining therapeutic alternatives.
Despite their clinical benefits, the use of bispecific antibodies comes with important considerations. Treatment-related toxicities such as cytokine release syndrome (CRS), neurotoxicity, and increased risk of infections must be anticipated and managed proactively. Appropriate patient monitoring and early intervention are essential to ensure safety and optimize outcomes. Moreover, as bispecifics begin to move into earlier lines of therapy and are used in combination with other agents, careful attention is needed to balance efficacy with tolerability, especially in older or more frail patients. Understanding each agent’s unique safety profile and tailoring supportive care accordingly will be critical to maximizing their long-term utility.
Looking ahead, the continued evolution of bispecific antibody therapy in multiple myeloma holds significant promise. Ongoing clinical trials are investigating their use in frontline settings and exploring novel targets to improve specificity and reduce off-target effects. There is also increasing interest in combining bispecifics with other immunomodulatory or targeted agents to deepen responses and potentially achieve longer-lasting remissions. As this class of therapies matures, multidisciplinary care, real-world data collection, and thoughtful sequencing strategies will be essential to integrating bispecific antibodies into routine clinical practice and improving outcomes for patients across the myeloma disease continuum.
