Richard Edelson began his career at NCI, where he was training to become a cancer immunologist.

“Just while I was there as a particularly young person starting my career, the entire area of T-cell immunity broke wide open, and it was very natural for me since I was already trained as a dermatologist with a special interest in cancer,” Edelson, Anthony N. Brady Professor of Dermatology at Yale School of Medicine said in a recording of the Yale Cancer Answers podcast. 

Edelson spoke with Anees Chagpar, professor of surgery in the Department of Surgery at Yale School of Medicine. They spoke about the development of anti-cancer vaccines, particularly in cutaneous T-cell lymphoma.

“It was very, very simple for me to apply the early T cell biology techniques to looking at malignancies of what turned out to be T cells,” he said. 

At NCI, Edelson, along with his mentors, discovered something career-shaping. 

“When those T cell malignancies start, they extremely commonly start, clinically, as a rash in the skin, a rash that can be very difficult to distinguish at the outset from non-malignant rashes,” he said. “I became fascinated with why that was. 

“What we found very quickly, and essentially shaped my career, was that malignant T cells come, of course, from normal T cells and it is those normal T cells that give rise to this cutaneous T-cell lymphoma that has a tendency to affect the skin, come from a normal T cell discovered because of the malignancy that itself circulates between the skin and the blood,” he said. 

After graduating from Hamilton College as a chemistry major, Richard Edelson received his MD from the Yale School of Medicine. He then sequentially trained in internal medicine at the University of Chicago, dermatology in the Harvard Program, and cancer immunology at NIH. 

Before being recruited back to his alma mater as chairman and professor of the YSM Department of Dermatology in 1986, he was director of the Immunobiology Group in Columbia University’s Comprehensive Cancer Center, associate director of that institution’s General Clinical Research Center, and professor and director of research in Columbia’s Dermatology Department.

While on the Yale faculty, he served continuously as chairman of the Department of Dermatology (1986-2022), and at overlapping times, has also been the director of the Yale University Comprehensive Cancer Center (2003-2009), YSM deputy dean overseeing all clinical departments (2000-2003), Leader of the YSM Cancer Center’s Lymphoma Research Program and the YSM faculty representative to the Yale New Haven Hospital Board of Trustees. 

On Oct. 1, 2022, after serving as departmental chairman for 37 years (the longest duration of any Yale University departmental chairman in University history), he resigned the position, while remaining a full-time professor of dermatology.

He was recently announced as the recipient of the first Advanced Research Projects Agency for Health (ARPA-H) grant in the United States, which is an outgrowth of President Biden’s Cancer Moonshot program. 

The nearly $25 million award, titled “Curing the Uncurable via RNA Encoded Immunogene Tuning,” aims to train the immune system to better fight cancer and other diseases by educating specific immune cells with mRNA technology. Philip Santangelo, of Emory and Georgia Tech, is the principal investigator, who will provide designer mRNA, and Edelson is a co-principal investigator on the project.

The immune system can be a powerful tool to control cancer. Immune cells within our body detect cancer cells and release payloads that kill them. Transformative science in the last decade has led to the development of therapies that enhance the ability of our immune cells to carry out this function. These therapies, including checkpoint blockade and CAR-T cells, have been lifesaving for many patients that before had untreatable cancer. But, sadly, a majority of patients with advanced solid tumors still succumb to their disease. 
Orca Bio, a late-stage biotechnology company, on March 17 announced results from the pivotal phase III Precision-T study of Orca-T, its lead investigational allogeneic T-cell immunotherapy, in patients with acute myeloid leukemia, acute lymphoblastic leukemia, high-risk myelodysplastic syndrome and mixed-phenotype acute leukemia. Orca-T is manufactured using highly purified regulatory T-cells, hematopoietic stem cells and conventional T-cells derived from peripheral blood from either related or unrelated matched donors.
Researchers from the University of Chicago Medicine Comprehensive Cancer Center demonstrated the potential of a novel treatment approach including immunotherapy to treat advanced human papillomavirus-negative head-and-neck squamous cell carcinoma. More than half of study participants had 50% or more of their tumors shrink after receiving the immunotherapy drug nivolumab with chemotherapy, followed by response-adaptive chemo-radiation therapy.
