Side effects of CAR-T cell therapy
Like all cancer treatments, CAR T-Cell therapies have serious side effects, such as a mass death of antibody-producing B cells and infections. Cytokine release syndrome (CRS) is one of the most common and severe side effects. T cells release chemical messengers (cytokins) which stimulate and direct immune responses as part of immune-related duties.
In the case of CRS, the infused T cells flood the bloodstream with cytokines, resulting in serious side effects such as highly elevated fevers and sudden drops in blood pressure. Severe CRS can be fatal in some cases. Another primary concern with CAR T-Cell therapies is neurologic side effects such as extreme confusion, seizure-like activity, and impaired speech. The exact cause of these neurologic side effects (immune effector cell-associated neurotoxicity syndrome, or ICANS) is unknown.
The CD19 segment dominated the CAR-T cell therapy market in 2024.

Centralized facilities, typically operated by pharmaceutical companies, can implement rigorous quality control measures and minimize variability in the manufacturing process. This is crucial for maintaining consistent product quality and safety, especially for autologous CAR T therapies, where each patient receives a personalized treatment. The complex and labor-intensive nature of autologous CAR T manufacturing favored centralized facilities equipped with the infrastructure and expertise for large-scale production, which is essential for the initial commercialization of CAR T therapies.
The in vivo CAR T therapy segment is experiencing the fastest growth in the market. This rapid growth is primarily because in vivo CAR T therapy offers several significant advantages over traditional ex vivo methods. These advantages include reduced manufacturing complexity, lower costs, faster turnaround times, and potentially broader patient access. In vivo methods bypass the labor-intensive and time-consuming ex vivo process of cell modification and expansion, which involves collecting a patient's T cells, genetically modifying them in a laboratory, and then reinfusing them. Instead, in vivo methods deliver the CAR gene directly into the patient's T cells within the body, often using engineered nanocarriers or viral vectors.
The viral vectors segment dominated the global market in 2024 due to their high transduction efficiency and ability to achieve stable gene expression, particularly with lentiviral and retroviral vectors. These vectors effectively integrate the CAR gene into the host T cell's genome, ensuring sustained expression of the therapeutic protein and long-term efficacy. While safety concerns exist, advancements in vector design and manufacturing processes are continuously being made to minimize these risks. Integration into the host cell's genome ensures that the CAR gene is maintained and expressed throughout the cell's life, including its progeny.
The dual and multiple antigen targeting CAR T-cell segment is experiencing the fastest growth during the forecast period. This growth is attributed to its ability to overcome tumor antigen escape, a significant challenge in CAR T-cell therapy. By targeting multiple antigens, these CAR T-cells can continue to recognize and attack cancer cells even if one antigen is lost. This approach enhances the effectiveness of the therapy, particularly in solid tumors where antigen heterogeneity and varying expression levels are common. Additionally, dual and multiple targeting improve overall anti-tumor activity and patient survival compared to single-antigen targeting.
