Multiple myeloma is a complex cancer of plasma cells that sits at the crossroads of hematology and oncology. For many patients, the goal has shifted from simple disease control to achieving deeper, longer lasting remissions and, in some cases, meaningful reversal of disease burden. The last decade has seen a steady expansion of options, driven by advances in targeted medicines, immunotherapy, and personalized cellular therapies. While there is no universal method that guarantees reversal for every patient, a growing toolbox now includes combinations that can suppress disease to very low levels and even render measurable remissions in a substantial subset of patients.
Traditional backbone therapies remain central in many treatment plans. Proteasome inhibitors and immunomodulatory drugs, often used in combination with steroids, form a core strategy for many newly diagnosed and relapsed patients. Autologous stem cell transplantation, when appropriate based on age and overall health, continues to be a standard of care for eligible individuals, typically after initial induction therapy. Monoclonal antibodies that target specific proteins on myeloma cells also play a major role, frequently in combination regimens designed to maximize responses and prolong progression-free survival. These options are provided through established pharmaceutical networks and delivered by specialized cancer centers around the world.
A newer class of therapies focuses on engineering the patient’s own immune system to fight the cancer. Chimeric antigen receptor T cell therapy, or CAR-T therapy, has emerged as a promising approach for relapsed and refractory multiple myeloma. In CAR-T therapy, a patient’s T cells are collected, modified in a manufacturing facility to recognize a myeloma-associated target, and then infused back to attack malignant cells. Two leading products in this space have become widely discussed in clinics and hospitals: Carvykti and Abecma. Both therapies are designed to recognize BCMA, a protein commonly found on myeloma cells, but they come from different developers and have distinct clinical and logistical considerations. These treatments are typically reserved for patients who have undergone prior lines of therapy and are evaluated at specialized centers with experience in managing potential side effects and the complex logistics of cellular therapy.
Carvykti, developed through a collaboration between Janssen and Legend Biotech, has been studied in diverse patient groups and is offered at major cancer centers that provide CAR-T administration. Abecma, developed by Bristol Myers Squibb with bluebird bio, has also shown meaningful responses in relapsed and refractory disease and is administered at designated treatment centers with comparable infrastructure for CAR-T administration. When deciding between these options, patients and clinicians consider factors such as prior therapies, overall health, center experience, manufacturing timelines, and the center’s ability to monitor for and manage potential adverse events like cytokine release syndrome and neurotoxicity. In practice, both therapies are part of a larger ecosystem that includes other immune-based approaches, targeted therapies, and access to clinical trials.
