Access to CAR T-cell therapy: Focus on diversity, equity and inclusion

Chimeric antigen receptor T-cell (CAR T-cell) therapy has revolutionized the treatment of hematologic malignancies in patients with relapsed or refractory disease without other treatment options. However, only a very small proportion of patients with an indication for CAR T-cell can access the treatment. The imbalance between supply and demand is magnified in minority and vulnerable populations. Limited access is multifactorial and in part a result of factors directly related to the cellular product such as cost, complex logistics and manufacturing limitations. On the other hand, the impact of diversity, equity, and inclusion (DEI) and their social and structural context are also key to understanding access barriers in cellular therapy and health care in general. CAR T-cell therapy provides us with a new opportunity to better understand and prioritize this gap, a key step towards proactively and strategically addressing access. The aim of this review is to provide an analysis of the current state of access to CAR T therapy with a focus on the influence of DEI. We will cover aspects related to the cellular product and the inseparable context of social and structural determinants. Identifying and addressing barriers is necessary to ensure equitable access to this and all future novel therapies.
