PHILADELPHIA, Oct. 25, 2023 /PRNewswire/ -- Carisma Therapeutics Inc. (Nasdaq: CARM) ("Carisma" or the "Company"), a clinical-stage biopharmaceutical company focused on discovering and developing innovative immunotherapies, today announced that new pre-clinical data leveraging an mRNA platform to develop in-vivo chimeric antigen receptor macrophage ("CAR-M") will be presented as a late-breaking abstract (#LBA1514) at the upcoming Society for Immunotherapy of Cancer (SITC) 38th Annual Meeting held from Wednesday, November 1, to Sunday, November 5, 2023, in San Diego, California. Two posters highlighting next-generation enhancements to Carisma's CAR-M platform, including a custom intronic shRNA approach and data on Engineered Microenvironment Converters (EM-C), will also be presented. Additionally, Carisma will share a trial-in-progress poster overviewing its Phase 1 first-in-human (FIH) study design of its lead program, CT-0508, sharing objectives and eligibility criteria.

Carisma will participate in the virtual SITC 2023 Annual Meeting Press Conference on Wednesday, November 1, 2023, from 12:00–1:30 pm PT.

"We are excited to present this pre-clinical data from our collaboration with Moderna for the first time," said Steven Kelly, President and Chief Executive Officer of Carisma. "Over the past year, we have leveraged the expertise of both companies to pioneer the development of in-vivo mRNA/LNP-based cell therapy. The study is exploring the potential for an off-the-shelf treatment approach to enhance therapeutic benefit for patients living with cancer."

About CT-0508

CT-0508 is a human epidermal growth factor receptor 2 (HER2) targeted chimeric antigen receptor macrophage (CAR-M). It is being evaluated in a landmark Phase 1 multi-center clinical trial that focuses on patients with recurrent or metastatic HER2-overexpressing solid tumors whose cancers do not have approved HER2-targeted therapies or who do not respond to treatment. Carisma is selecting participants who have tumors of any anatomical origin, but with the commonality of overexpressing the HER2 receptor on the cell surface, which is the target for our CAR-M. The Phase 1 clinical trial marks the first time that engineered macrophages are being studied in humans. The trial continues to enroll patients at seven clinical sites in the U.S., including (i) Penn Medicine's Abramson Cancer Center, (ii) the University of North Carolina Lineberger Comprehensive Cancer Center, (iii) the City of Hope National Medical Center, (iv) the MD Anderson Cancer Center, (v) the Sarah Cannon Cancer Research Institute, (vi) Oregon Health & Science University and (vii) Fred Hutchinson Cancer Center.

About Moderna

In over 10 years since its inception, Moderna has transformed from a research-stage company advancing programs in the field of messenger RNA (mRNA), to an enterprise with a diverse clinical portfolio of vaccines and therapeutics across seven modalities, a broad intellectual property portfolio and integrated manufacturing facilities that allow for rapid clinical and commercial production at scale. Moderna maintains alliances with a broad range of domestic and overseas government and commercial collaborators, which has allowed for the pursuit of both groundbreaking science and rapid scaling of manufacturing. Most recently, Moderna's capabilities have come together to allow the authorized use and approval of one of the earliest and most effective vaccines against the COVID-19 pandemic.

Moderna's mRNA platform builds on continuous advances in basic and applied mRNA science, delivery technology and manufacturing, and has allowed the development of therapeutics and vaccines for infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases and auto-immune diseases. Moderna has been named a top biopharmaceutical employer by Science for the past eight years. To learn more, visit
