Article Abstract
The US Food and Drug Administration has approved 3 chimeric antigen receptor (CAR) T-cell therapies. For continued breakthroughs, novel CAR designs are needed. This includes different antigen-binding domains such as antigen-ligand binding partners and variable lymphocyte receptors. Another recent advancement in CAR design is Boolean logic gates that can minimize on-target, off-tumor toxicities. Recent studies on the optimization of costimulatory signaling have also shown how CAR design can impact function. By using specific signaling pathways and transcription factors, CARs can impact T-cell gene expression to enhance function. By using these techniques, the promise of CAR T-cell therapies for solid tumors can be fulfilled.

Multiple myeloma (MM) is a malignant disease in which clonal plasma cells proliferate abnormally. In patients with MM, the number and function of NK cells are suppressed, resulting in reduced immune surveillance and clearance of myeloma cells. Restoring or enhancing the killing effect of NK cells on myeloma cells is an important strategy for MM immunotherapy.

Plasma cell myeloma (multiple myeloma) is a blood cancer characterized by the clonal proliferation of plasma cells in the bone marrow. Treatment strategies evolve year by year, new drugs getting Food and Drug Administration (FDA)-approved each year. Chimeric antigen receptor (CAR) therapies are an advanced form of immunotherapy that engineer T cells to recognize and destroy cancer cells.

Lymphomas are a group of malignant proliferations of B, T or NK-lymphoid cells at different stages of maturation. While they primarily occur in lymph nodes or lymphatic tissues, they can also involve bone marrow, blood, or other organs. Despite advances in treatment, many patients experience relapse, or develop refractory disease, prompting the development of new therapies.

Chimeric antigen receptor (CAR)-macrophage therapy is a promising approach for tumour treatment due to antigen-specific phagocytosis and tumour clearance. However, the precise impact of tumour burden, dose and dosing regimens on therapeutic outcomes remains poorly understood. We developed ordinary differential equation (ODE) mathematical modelling and utilised parameter inference to analyse in vitro FACS-based phagocytosis assay data testing CD19-positive Raji tumour cell against CAR-macrophage, and revealed that phagocytosing efficiency of CAR-macrophage increases but saturates as both Raji cell and CAR-macrophage concentrations increase.

In patients with relapsed/refractory (R/R) large B-cell lymphoma (LBCL) who are either refractory to first-line therapy or relapse within 12 months, chimeric antigen receptor (CAR) T-cell therapy is more effective than salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) as second-line therapy. Adoption of CAR T-cell therapy into routine clinical practice involves a period of adaptation and refinement of clinical processes. We aimed to document the evolution of clinical processes for CAR T-cell therapy during 2022 and 2023, and compare healthcare resource utilization (HCRU) associated with CAR T-cell and ASCT processes in routine clinical practice.
