Abstract
Chimeric antigen receptor T-cell (CAR-T)-mediated therapies have shown promising clinical benefit in patients with refractory or relapsing (R/R) diffuse large B-cell lymphoma (DLBCL). However, CAR-T treatment presents challenges such as lack of drug accessibility, financial barriers, variable physician preference or experience, and risk assessment based on patient-specific characteristics. This article thus aims to provide an overview of the CAR-T landscape for R/R DLBCL in Asia, with a focus on identifying barriers to access, from the perspective of Asian and international lymphoma experts. Presently, existing clinical data indicate that CAR-T therapy is a potentially curative strategy for R/R DLBCL in addition to stem cell transplantation, provided the patient's disease profile and treatment history have been thoroughly considered. However, longer-term follow-up data from large-scale studies are needed to confirm curative potential and define optimal sequencing of CAR-T in the context of novel emerging treatments, such as bi-specific antibodies, in the management of R/R DLBCL. Consequently, further research into CAR-T would benefit from collaboration between institutions. Furthermore, there is a wide disparity in CAR-T accessibility across regions due to complicated logistics and cost, which represent a significant barrier to patients in Asia. Hence, there is a need to increase representation and engagement across different stakeholders such as policymakers, payers, and the industry to arrive at a consensus on patient selection, establish clear guidelines, and develop strategies to lower CAR-T costs. Ultimately, data can support a multi-stakeholder approach when devising strategies to make CAR-T feasible and sustainable for patients.
