Carisma Therapeutics Inc. is a U.S.-based biotechnology company that was built around macrophage engineering for serious diseases such as liver fibrosis and cancer. In its recent filings, the company says it has ceased further development of its lead programs CT-0508 and CT-0525 and does not intend to resume its historical research and development activities. Instead, Carisma is focused on preserving cash, monetizing remaining assets, and pursuing an orderly wind down of operations. The company also has a material strategic transaction context, including the planned OrthoCellix merger described in its 2025 filings.
