Background
In 3/2021, chimeric antigen receptor (CAR) T-cell therapy was approved for the treatment of multiple myeloma in adult patients with refractory disease. Currently, only the Veterans Affair (VA) center at the Tennessee Valley Healthcare System (TVHS) offers this treatment. Herein, we report a significant healthcare milestone in 2024 when the first patient received CAR T-cell therapy for multiple myeloma in the VA system. Additionally, the rate of hypogammaglobulinemia is the highest for CAR T-cell therapy using idecabtagene vicleucel compared to therapies using other antineoplastic agents (Wat et al, 2021). The complications of hypogammaglobulinemia can be mitigated by intravenous immunoglobulin (IVIG) treatment.
Case Presentation
A 75-year-old male veteran was diagnosed with IgA Kappa multiple myeloma and received induction therapy with bortezomib, lenalidomide, and dexamethasone in 2014. The patient underwent autologous stem cell transplant (SCT) in the same year. His disease recurred in 3/2019, and the patient was started on daratumumab and pomalidomide. He received another autologous SCT in 2/2021, to which he was refractory. The veteran then received treatment with daratumumab and ixazomib, followed by carfilzomib and cyclophosphamide. Starting in 9/2022, the patient also required regular IVIG treatment for hypogammaglobulinemia. He eventually received CAR T-cell therapy with idecabtagene vicleucel at THVS on 4/18/2024. The patient tolerated the treatment well and is undergoing routine disease monitoring. Following CAR T-cell therapy, his hypogammaglobulinemia persists with immunoglobulins level less than 500 mg/dL, and the veteran is still receiving supportive care IVIG.
Discussion
A population estimate of 1.3 million veterans are uninsured and can only access healthcare through the VA (Nelson et al, 2007). This case highlights the first patient to receive CAR T-cell therapy for multiple myeloma in the VA system, indicating that veterans now have access to this life-saving treatment. The rate of hypogammaglobulinemia following CAR T-cell therapy for multiple myeloma is as high as 41%, with an associated infection risk of 70%. Following CAR T-cell therapy with idecabtagene vicleucel, around 61% of patients will require IVIG treatment (Wat el al, 2021). Our case adds to this growing literature on the prevalence of IVIG treatment following CAR T-cell therapy in this patient population.
