CAR-T Cell Therapy: Managing Side Effects and Overcoming Challenges.

Abstract

Chimeric antigen receptor T (CAR-T) cell therapy is an innovative and promising approach to treat cancer. Clinical trials have demonstrated remarkable results, providing hope for patients who have exhausted more traditional therapies. However, this new therapy is not without challenges, as significant side effects have been associated with it. Cytokine release syndrome (CRS) is a widely recognized and consequential side effect of CAR-T cell therapy. Neurological toxicity is another potential side effect that can cause confusion and seizures in some patients. Hematologic toxicities, such as anemia and thrombocytopenia, can increase the risk of bleeding or infection. B-cell aplasia can also occur, leading to increased vulnerability to infections. Strategies to reduce the incidence and severity of toxicities include suicide, endogenous, and exogenous switches to modulate the activity of the immune system toward cancer while minimizing toxicity. Despite the obstacles faced by CAR-T cell therapy, continuous research and development in this area offer considerable potential for improving this treatment as a more reliable and efficient method for treating cancer.
