Carisma Therapeutics develops chimeric antigen receptor macrophages (CAR-Macrophages) to target solid tumors by engineering a patient's own immune cells to enhance tumor infiltration and activate anti-tumor immunity. This approach addresses the challenges of immunosuppressive tumor microenvironments and antigen heterogeneity, offering a potential long-term treatment strategy for cancer patients.

Problem
Solid tumors create immunosuppressive microenvironments that block the infiltration of T and NK cells, shutting down immune responses. Significant cell-to-cell heterogeneity within a tumor mass allows for the development of resistance to single-antigen targeted therapies. Current cell therapies struggle to effectively target and eliminate solid tumors due to these challenges.
Solution
Carisma Therapeutics develops chimeric antigen receptor macrophages (CAR-Macrophages) to overcome the limitations of existing cancer therapies. This approach engineers a patient’s own monocytes and macrophages to target solid tumors, enhancing tumor infiltration and activating both innate and adaptive anti-tumor immunity. CAR-Macrophages are designed to be actively recruited into tumors and locked into an anti-tumor phenotype, driving T cell recruitment and immune activation within the tumor microenvironment. By leveraging macrophages as professional antigen-presenting cells, the therapy can activate the patient’s adaptive immune system against multiple tumor-specific antigens, addressing antigen heterogeneity. This multi-pronged attack on tumors offers a potential long-term treatment strategy for cancer patients.
Target Audience
The primary target audience includes patients with solid tumors and their families, as well as healthcare providers specializing in oncology and immunotherapy.
