Anti-allergy Drug Dupilumab Treats Lung Cancer

Moreover, in an initial human study, pairing immunotherapy with dupilumab—an antibody that blocks the Interleukin-4 (IL-4) receptor commonly used to manage allergies and asthma—enhanced patients’ immune systems. Among six patients, one saw a notable reduction in their tumor size. The findings were described in the December 6 issue of

.

“Immunotherapy using checkpoint blockade has revolutionized treatment for non-small cell lung cancer, the most common form of lung cancer, but currently only about a third of patients respond to it alone, and in most patients, the benefit is temporary,” says senior study author Miriam Merad, MD, PhD, Director of the Marc and Jennifer Lipschultz Precision Immunology Institute and Chair of the Department of Immunology and Immunotherapy at the Icahn School of Medicine at Mount Sinai. “A big focus of our program TARGET is to use single cell technology and artificial intelligence to identify molecular immune programs that can dampen tumor immune response to checkpoint blockade.”

Also known as a PD1 inhibitor, checkpoint blockade is a type of cancer immunotherapy that can unleash the cancer-killing activity of T cells.

“Using single cell technologies, we discovered that the immune cells infiltrating lung cancers, as well as other cancers we studied, exhibited characteristics of a ‘type 2’ immune response, which is commonly associated with allergic conditions like eczema and asthma,” says first study author Nelson LaMarche, PhD, a postdoctoral research fellow in the lab of Dr. Merad.

“These results led us to explore whether we could repurpose a medication typically used for allergic conditions to ‘rescue’ or enhance tumor response to checkpoint blockade,” says Thomas Marron, MD, PhD, Director of the Early Phase Trial Unit at Mount Sinai’s Tisch Cancer Center, and co-senior author of the study. “In fact, one patient whose lung cancer was growing despite checkpoint blockade had nearly all their cancer disappear after receiving just three doses of the allergy medication, and his cancer remains controlled today, over 17 months later.”

The researchers are encouraged by the initial results but emphasize the need for larger clinical trials to validate the drug’s efficacy in treating NSCLC. Beyond the clinical trial findings reported in the current Nature paper, the investigators have now expanded the clinical trial, adding dupilumab to checkpoint blockade for a larger group of lung cancer patients, and Dr. Marron recently received a grant from the Cancer Research Institute to study the effects in early-stage lung cancer as well. Through these trials, they are searching for biomarkers that can predict which cancer patients might benefit from dupilumab treatment and which may not.

“In our relentless pursuit of progress, the Cancer Research Institute (CRI) proudly supports the visionary team at the Icahn School of Medicine at Mount Sinai. Their findings validate our commitment to funding research across the entire discovery continuum, from the lab to clinical implementation, driven by cutting-edge technology and data. We’re eager to witness our support delivering new hope by uncovering pathways to enhance checkpoint blockade responses. We champion this discovery and take pride in being part of its journey from lab to clinic, reinforcing our commitment to transforming lives,” says Jill O’Donnell-Tormey, PhD, CEO and director of scientific affairs at CRI.
