Background
In 2024, the first two veterans, both from the Michael E. DeBakey Veteran Affairs (VA) Medical Center, received chimeric antigen receptors (CAR) T-cell therapy for refractory multiple myeloma through the Tennessee Valley Healthcare System (TVHS). Currently, TVHS is the only VA where this treatment is available. One of these patients also had penta-refractory multiple myeloma (P-RMM), which is associated with significantly worse progression-free survival and overall survival (OS) (Gill et al, 2021). P-RMM is defined as resistance to at least two immunomodulatory drugs, two different proteasome inhibitors, and one CD38 monoclonal antibody.
Case Presentation
A 71-year-old female veteran was diagnosed with high-risk multiple myeloma and received induction therapy with carfilzomib, lenalidomide, and dexamethasone in 2017. She underwent autologous stem cell transplant (SCT) in 4/2018. The veteran subsequently received maintenance therapy with lenalidomide, bortezomib, and dexamethasone. Her disease recurred in 1/2022. The patient then received two more lines of treatments with daratumumab and pomalidomide followed by selinexor. She had another autologous SCT in 5/2023, to which she was refractory. Her fifth line therapy included addition of bortezomib to her selinexor regimen. She eventually underwent CAR T-cell therapy at THVS on 5/1/2024 with good tolerance of therapy. At her follow-up visit, the patient had significant response to CAR T-cell treatment, based on her symptoms and improvement in free light chains and serum protein electrophoresis.
Discussion
CAR T-cell therapy is one of the newest and most cutting-edge therapies for patients with refractory multiple myeloma. Access to this therapy has been limited throughout the country. However, as shown by our case, this life-saving treatment is now available to patients within the VA. According to a retrospective study on P-RMM patients, the OS in patients who received B-cell maturation antigen (BCMA) targeted therapy was significantly higher than in those who did not (17 vs. 6 months, p < 0.0001). Among the BCMA-targeted therapies, CAR T-cell therapy is associated with the highest OS (29 months) compared to antibody-drug conjugates and bispecific T-cell engagers (Atrash et al, 2023). Thus, accessibility to CAR T-cell therapy was essential in our patient with P-RMM in ensuring her best survival outcomes.
