Although the CAR-T treatments for myeloma can deliver longer remission times, they are not curative. Results of trials with anti-myeloma CAR-T cell treatments have so far been impressive, delivering good response rates and remission times in heavily pre-treated patients (on average six lines of treatment) with treatment-resistant myeloma.

How does CAR T cell therapy work for multiple myeloma?
Your doctor puts them back into your body through an IV, where they seek out and kill cancer cells. CAR T cells can stay alive in your body and keep attacking cancer cells for many years. CAR T-cell treatments for multiple myeloma target a protein called B-cell maturation antigen (BCMA).

Why do CAR T cells not work for solid tumors?
“One of the main limitations is that most of the proteins present on solid tumors that could be used as targets are also found at low levels on normal cells, making it difficult to specifically direct the CAR T cells against tumor cells and spare healthy ones,” said presenter John Haanen, MD, PhD, a medical oncologist ...

Chimeric antigen receptor (CAR) T-cell therapies have achieved remarkable clinical success in B-cell malignancies. This scope of research has more recently been extended to the field of myeloma.
What is the treatment for multiple myeloma?
Researchers are finding new ways to fight multiple myeloma, including a new treatment called CAR T-cell therapy. It's still experimental, but you may get a chance to join a clinical trial if your other treatments aren't working. CAR T-cell therapy works differently from other cancer treatments. It trains your immune system to find and kill cancer.
What are the side effects of car T cells?
One of the most common side effects from CAR T-cell therapy is called cytokine release syndrome (CRS). It's an immune response that's triggered by a flood of immune system chemicals called cytokines into your body. CRS causes symptoms like: Fast heartbeat. Low blood pressure.

However, the disease remains challenging, as relapse and disease progression remain common, even after complete remission. Myeloma often mutates and becomes more resistant to subsequent lines of therapy, leading to shorter responses and remissions.
What is the treatment for multiple myeloma?
CAR-T cell treatments are available for several forms of blood cancer, including multiple myeloma and different types of leukemia and lymphoma. The U.S. Food and Drug Administration (FDA) approved a specific type of CAR-T cell therapy for multiple myeloma in March 2021. In this treatment, CAR-T cells are engineered to recognize a protein called B-cell maturation antigen (BCMA). Cancerous plasma cells often have BCMA on their outer surface, making it easy for CAR-T cells to find and kill them. This approved CAR-T cell treatment is called Abecma (idecabtagene vicleucel) or ide-cel.

CAR-T cells can remain in the body for many months and may help prevent cancer from returning. After receiving a CAR-T cell infusion, people often have to stay in the hospital for several weeks.
What is the target of CAR T cells?
The best known and explored target for CAR-T cells so far is CD19. This is an antigen of normal B cells that is also present on B cell leukemias and lymphomas (24, 25). But when it comes to multiple myeloma, which is also B cell neoplasia, CD19 is present only on a subset of malignant cells (26).

However, even with CAR-T cell therapy, the majority of patients eventually relapse, which is the greatest limitation of this therapy. Serious adverse events such as cytokine release syndrome or neurotoxicity should also be considered as possible side effects of CAR-T cell therapy.
Does multiple myeloma relapse?
However, despite the current improvements in the prognosis of this malignancy, it always ends with relapse, and therefore new therapy approaches for destroying resistant cancer cells are needed.
What is the T cell in myeloma?
The major CAR T-cell therapies in trials for multiple myeloma are directed toward B-cell maturation antigen (BCMA), a surface antigen expressed on B cells starting from their period of development in the germinal centers onward and persist ing through the time of plasma cell differentiation. BCMA is minimally expressed in normal human tissues but is heavily expressed on myeloma plasma cells. This allows for safe and intentional targeting of neoplastic myeloma cells using CAR T-cell technology.
What is car T cell therapy?
CAR T-cell therapy is a 1-time treatment that allows patients to achieve deep and durable remissions without the need for the usual continuous cancer-directed treatments. The aforementioned trials and therapies have paved the way for subsequent iterations of cellular therapies. These include non–BCMA-targeted CAR T cells; next-generation CAR T cells with improved costimulatory domains for improved safety, efficacy, or faster production; and allogeneic CAR T cells derived from pluripotent stem cells available off the shelf to patients. In the coming year, as commercially available myeloma CAR T-cell therapies are approved, it will be even more important for community oncologists to better understand these therapies so they can offer them to their patients.
