During the past decades, CART therapy has achieved good results in hematoma, but the effect of CAR-T on solid tumors is not so obvious. The main reason is that T cells are difficult to infiltrate the solid tumor microenvironment and are easy to be depleted in the tumor microenvironment. As an important immune cell, macrophage has an infiltration rate of up to 50% in solid tumors, and it is often one of the first cells absorbed by solid tumors and can selectively kill cancer cells through phagocytosis. Based on the above features, several researchers have turned to CAR-M exploration. Compared with CAR-T therapy, CAR-M has good tumor invasion and the capability to change the tumor microenvironment. Meanwhile, macrophages do not need complex antigen recognition mechanisms and can directly engulf and eliminate those cells that appear abnormal, which is more likely to have an effect on solid tumors.

For CAR-M development, there are also some obstacles at present. Firstly, macrophages are naturally resistant to commonly used viral vectors. Macrophages serve as the body's first defense line against cancer cells and viruses, which makes it difficult to modify macrophages to attack cancer through common viral vectors. Secondly, the biggest problem lies in the tumor microenvironment of solid tumors, tumor-associated macrophages as a critical cell type in the tumor microenvironment, not only suppress the immune cell functions but also promote tumor growth. So, how to better balance the M1-M2 function will be an important difficulty. Thirdly, the problem of macrophage cell amplification. Unlike T cells, which can be cloned and expanded in large numbers in the laboratory, macrophages do not expand in vitro, and it is a great challenge to obtain a large number of macrophages.

Creative Biolabs has developed an innovative and proprietary platform for next-generation CAR-engineered macrophage cell therapies (CAR-MA) with great therapeutic potential for intractable solid tumors. Given the special characteristics of macrophages, our approach is to use the macrophages isolated from the primary monocytes, THP1 cell line or iPSC programmed macrophages, and genetically engineer them to express a CAR against the specific tumor antigen. The CAR-engineered macrophage cell products can be used for in vitro or in vivo phagocytosis assays to evaluate the CAR-MA efficacy. The macrophage cell types used for CAR engineering include:

Induced pluripotent stem cells (iPSCs)-derived macrophage (iMac).
Primary monocytes-derived macrophage.
Macrophage cell lines (THP1, J774A.1, Raw264.7, etc.).
