Kim A. Reiss, MD, on HER2-Overexpressing Solid Tumors: First-in-Human Study of Anti-HER2 CAR Macrophages
SITC 2021
Kim A. Reiss, MD, of the University of Pennsylvania, discusses results of a phase I trial of a CAR-M engineered macrophage cancer therapy, known as CT-0508, for patients with solid tumors that overexpress HER2. CAR-M, designed to exploit the natural role of macrophages to initiate an antitumor response, is currently under study at multiple clinical sites (Abstract 951).

John M. Kirkwood, MD, of the University of Pittsburgh Medical Center, discusses phase Ib findings on the combination of vidutolimod plus pembrolizumab, as well as vidutolimod monotherapy, both of which showed clinical activity in patients with PD-1 blockade–refractory melanoma. The duration of response with the combination therapy was substantially longer. Phase II studies are ongoing (Abstract 950).

Emily Z. Keung, MD, of The University of Texas MD Anderson Cancer Center, discusses the complex interactions of immune infiltrates and neoadjuvant immune checkpoint blockade (ICB) in patients with resectable soft-tissue sarcoma. These interactions may hold the key to understanding pathologic response to ICB and ICB resistance (Abstract 379).

Mehmet Altan, MD, of The University of Texas MD Anderson Cancer Center, discusses findings from a phase Ib dose-escalation study, which showed early evidence of activity for NKTR-255, an investigational IL-15 receptor agonist, plus cetuximab in patients with solid tumors. Treatment appeared to lead to expansion and proliferation of NK and CD8+ cells (Abstract 957).

Patrick Hwu, MD, of Moffitt Cancer Center and President of the Society for Immunotherapy of Cancer (SITC), and Mary Dean, JD, CAE, SITC Executive Director, discuss the organization’s mission, strides made in cancer immunology, meeting the challenge of immunoresistance, and the new SITC app for clinical practice guidelines. This app places a useful tool in the hands of health-care providers, one that can be continually updated as the science evolves.

Yevgeniy R. Semenov, MD, of Massachusetts General Hospital and Harvard Medical School, discusses new findings suggesting cutaneous adverse events such as vitiligo, lichenoid dermatitis, and psoriasis—which often occur in patients with cancer who receive immune checkpoint inhibitors—may be strongly associated with response to therapy and a 22% reduction in mortality (Abstract 814).
