| Method | vitro experiments | |
| Cell Lines | CAR-T cells | |
| Concentrations | 0.5 μM | |
| Incubation Time | 16 h | |
| Results | In contrast, the condition containing Cobi alone showed significantly reduced lytic capacity of the CAR-T cells, and this lytic capacity was even further reduced in the additional presence of Vem. |

| Concentrations | 0.5 μM | |
| Incubation Time | 16 h | |
| Results | The presence of Vem alone, Tram alone,Cobi alone, Vem + Cobi, and Dabra + Tram, but not of Dabra alone seemed to reduce these quantities to approximately 50%. |
