CT – 0508 (HER2)
Discovery | Preclinical | Phase 1

Driven to discover and develop
new immunotherapies

Carisma is developing CT-0508 to target HER2-positive solid tumors. While its expression in normal tissues is low, HER2 is highly expressed in a wide range of solid tumors and plays an active role in both malignant transformation and tumor aggressiveness by promoting cancer cell proliferation, invasion and metastasis.


Aiming to address the unmet needs of patients

CT-0508 is a human epidermal growth factor receptor 2 (HER2) targeted chimeric antigen receptor macrophage (CAR-Macrophage). In pre-clinical studies Carisma’s CAR-Macrophage cell therapies have demonstrated the ability to traffic into the tumor, phagocytose and kill cancer cells, warm-up the tumor microenvironment, and attract and activate cells of the adaptive immune system, delivering a lasting attack against the cancer.

Leading the way in CAR-Macrophage cell therapy

CT-0508 is the first CAR-Macrophage cell therapy to enter clinical trials. Preclinical trials showed that the treatment has the potential to overcome the key challenges faced by other cell therapies in treating solid tumors.

The clinical study centers 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.

We are currently recruiting patients at:

  • Abramson Cancer Center of the University of Pennsylvania
  • Lineberger Comprehensive Cancer Center of the University of North Carolina
  • City of Hope in Duarte, California
  • MD Anderson Cancer Center
