Carisma Presents Pre-Clinical Proof of Concept for in vivo CAR-M using mRNA platform in collaboration with Moderna at SITC

- Data demonstrate feasibility, tolerability, and early efficacy of mRNA/LNP in vivo CAR-M therapy in pre-clinical models of metastatic solid tumors

- Proof of concept achieved for platform under the Moderna collaboration

- "In vivo CAR-M: Redirecting endogenous myeloid cells with mRNA for cancer immunotherapy" to be presented Friday, November 3, 2023, at 11:30 am PT

PHILADELPHIA, Oct. 31, 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 it will present new findings at the Society for Immunotherapy of Cancer (SITC) 38th Annual Meeting regarding its first-of-its-kind collaboration with Moderna. The collaboration aims to bring together Carisma's chimeric antigen receptor macrophage (CAR-M) platform with Moderna's mRNA and lipid nanoparticle (LNP) technologies to generate and develop in vivo CAR-M therapeutics.

Accepted as a late-breaking presentation, "In vivo CAR-M: Redirecting endogenous myeloid cells with mRNA for cancer immunotherapy," showcases data that demonstrate Carisma's CAR-M therapy can be directly produced in vivo, or within the body, successfully redirecting endogenous myeloid cells against tumor-associated antigens using mRNA/LNP. The pre-clinical data demonstrate feasibility, tolerability, and efficacy against metastatic solid tumors. This novel approach to cancer immunotherapy offers an off-the-shelf solution that has the potential to increase access to CAR-based therapies and will be the basis of CAR-M programs to be developed under the Carisma and Moderna collaboration.

"The data presented at SITC is incredibly exciting as it demonstrates that we have the ability to make CAR-M directly in vivo with mRNA/LNP technology, leading to robust and targeted anti-tumor activity," said Michael Klichinsky, PharmD, PhD, Co-Founder and Chief Scientific Officer at Carisma. "This off-the-shelf approach to treat cancer with engineered myeloid cells, developed in collaboration with Moderna, has the potential to transform the CAR field and be applied to numerous cancer targets and indications."

"We are pleased to share data about the successful application of our mRNA platform to advance in vivo cell therapy," said Lin Guey, PhD, Chief Scientific Officer of External Research Ventures at Moderna. "We look forward to the continuation of our pre-clinical work with Carisma and are optimistic that the joint scientific knowledge of both companies will accelerate the development of novel in vivo CAR-M therapies for patients."

Details of Carisma data accepted for presentation at the SITC 38th Annual Meeting are as follows:

• "In vivo CAR-M: Redirecting endogenous myeloid cells with mRNA for cancer immunotherapy" presented on Friday, November 3, 2023, at 11:30 am PT
• "CAR-Macrophages with custom intronic shRNA exhibit enhanced efficacy against solid tumors" presented on Friday, November 3, 2023, 9:00 am – 7:00 pm PT
• "Engineered Microenvironment Converters (EM-C): Macrophages expressing synthetic cytokine receptors reverse immunosuppressive signals in solid tumors" presented on Friday, November 3, 2023, 9:00 am – 7:00 pm PT
• "A Phase 1, First in Human (FIH) study of autologous macrophages engineered to express an anti-HER2 chimeric antigen receptor (CAR) in participants (pts) with HER2 overexpressing solid tumors" presented on Friday, November 3, 2023, 9:00 am – 7:00 pm PT

Presentation and posters will be available on the SITC 38th Annual Meeting portal for registered attendees.
