ATLANTA – Sarcomas of bone and soft tissues are considered to be “antigenically cold” tumors, with few identifiable mutations that may be susceptible to targeted therapies.
Some sarcoma subtypes such as osteosarcoma and rhabomyosarcoma, however, frequently express the human epidermal growth factor receptor 2 on tumor surfaces. Although HER2 expression in these tumors is at too low a level for HER2-targeted therapies such as trastuzumab (Herceptin), HER2 appears to be an opportunistic target for chimeric antigen receptor (CAR) T-cell therapy, according to Shoba Navai, MD, from Baylor College of Medicine, Houston.
In a video interview at the 2019 annual meeting of the American Association for Cancer Research, Dr. Navai describes her team’s early experience using a HER2-targeted CAR-T cell construct and preinfusion lymphodepletion in patients with advanced sarcomas.
Development of the CAR-T cell construct is supported by the Cancer Prevention & Research Institute of Texas, Stand Up to Cancer, the St. Baldrick’s Foundation, Cookies for Kids’ Cancer, Alex’s Lemonade Stand, and a grant from the National Institutes of Health. Dr. Navai reported having no disclosures.
