Elranatamab and Beyond: How Consolidated Therapy is Reshaping Multiple Myeloma Management
Infection risk following CAR T-cell therapy is a growing concern, but a new wave of data suggests a surprisingly effective strategy for improving outcomes: layering on additional immune-based therapies. Recent findings, shared at the International Myeloma Society (IMS) meeting and discussed with Pharmacy Times®, highlight the feasibility – and potential benefits – of consolidated therapy with T-cell engagers like elranatamab post-CAR T, offering a path towards deeper remissions and sustained disease control in relapsed or refractory multiple myeloma (RRMM).
The Pharmacist’s Critical Role in a Shifting Landscape
Pharmacists are increasingly central to navigating the complexities of these novel treatment sequences. Dr. Matthew Lei, clinical pharmacy specialist at Massachusetts General Hospital, emphasizes the need for proactive infection prophylaxis, particularly in the wake of CAR T. Updated NCCN guidelines now recommend primary prophylaxis with IVIG, placing pharmacists at the forefront of ensuring appropriate implementation of supportive care strategies. This includes vigilant monitoring for, and prophylaxis against, infections like VZV and Pneumocystis jirovecii pneumonia (PJP).
Beyond infection control, pharmacists are vital in mitigating cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Strategies like tocilizumab or dexamethasone prophylaxis are being explored, and pharmacists play a key role in outpatient monitoring, particularly for patients stepped down from inpatient care post-IDE-CEL (idecabtagene vicleucel). Effective collaboration with the medical team is paramount in selecting appropriate candidates for outpatient dosing and ensuring robust follow-up.
Consolidated Therapy: A Deeper Dive into the Data
The core takeaway from recent studies, including CARTITUDE-1, is that combining T-cell engagers or other immune-based therapies after CAR T-cell therapy is not only achievable but can lead to a deepening of response and increased rates of sustained minimal residual disease (MRD) negativity. This approach acknowledges that while CAR T can induce impressive remissions, they aren’t always durable. Consolidation aims to solidify those gains.
However, this sequential approach isn’t without its challenges. Patients often present with lingering cytopenias post-CAR T, requiring careful dose adjustments and supportive care. Furthermore, the specific antigen targeted – whether GPRC5D or BCMA – influences the toxicity profile, demanding a nuanced understanding of potential adverse events. Pharmacists must be prepared to manage these complexities and optimize treatment plans accordingly.
Looking Ahead: Sequential Strategies and Frontline Applications
The future of multiple myeloma treatment is likely to involve more frequent use of combination sequential strategies, not just in relapsed/refractory settings, but potentially even in the frontline. This shift necessitates a proactive approach to toxicity management and a deep understanding of the interplay between different immune-based therapies. The development of biomarkers to predict response and toxicity will be crucial in personalizing treatment and maximizing benefit.
The evolving treatment paradigm also highlights the importance of ongoing education for pharmacists. Staying abreast of the latest clinical trial data, guideline updates, and emerging therapies is essential to providing optimal care for patients with multiple myeloma. Resources like the National Cancer Institute’s myeloma information page can provide valuable updates and insights.
