CAR T cell therapy pioneer Carl June, the Richard W. Vague Professor in Immunotherapy in the Perelman School of Medicine and director of the Center for Cellular Immunotherapies (CCI) at Penn Medicine’s Abramson Cancer Center, has been named a winner of the 2024 Breakthrough Prize in Life Sciences for the development of chimeric antigen receptor (CAR) T cell immunotherapy, a revolutionary cancer treatment approach in which each patient’s T cells are modified to target and kill their cancer cells. The invention sparked a new path in cancer care, harnessing the power of patients’ own immune systems, a once-elusive goal that brought fresh options for those who could not be successfully treated with conventional approaches.

Founded in 2012, the Breakthrough Prizes are the world’s largest science awards, with $3 million awarded for each of the five main prize categories. June is the sixth Breakthrough Prize laureate from Penn, which joins Harvard and MIT among the institutions whose researchers have been honored with the most Breakthrough Prizes.

“This award is not only a testament to Dr. June’s outstanding contributions to science, but also a shining example of the caliber of discoveries and research which Penn faculty set their sights upon,” said Penn President Liz Magill. “We are immensely proud to have Dr. June as a member of the Penn academic community, and we know that CAR T cell therapy is just the first chapter in an inspiring and lifesaving new era of medicine.”

June is internationally recognized for his role in pioneering the CAR T cell therapy, which led to the first FDA-approved personalized cellular therapy, for children and young adults with the blood cancer known as acute lymphoblastic leukemia, in August of 2017—a step which has spurred five additional approvals of the technique in other blood cancers. June joined Penn in 1999, building momentum for Penn to become a global hub for cell and gene therapy. Gene-modified T cells engineered in June’s lab to retrain a patient’s own immune cells to attack cancer were used in the first clinical trial of CAR T cell therapy in 2010. Some of the earliest children and adults treated have experienced long-lasting remissions of 10 years or more. In addition to the FDA approvals that have made the therapy commercially available to patients across the world, thousands more have benefited from clinical trials testing these transformative treatments, including for the treatment of solid tumors and even autoimmune diseases like lupus.

“Dr. June’s tireless commitment to advancing T cell immunotherapy research has been life-changing for many patients affected by cancer, who have lived longer, fuller lives, thanks to the discoveries made in his lab,” said J. Larry Jameson,executive vice president of the University of Pennsylvania for the Health System and dean of the Perelman School of Medicine. “We are proud to see one of Penn’s most esteemed scientists recognized for the impact of his foundational work to develop a new class of cancer immunotherapy treatment.”

“QR Code for Cancer Cells” – Uncovering Why Some Cells Become Resistant to Anti-Cancer Therapies

by Win Reynolds

QR codeA research team led by engineers at the University of Pennsylvania and Northwestern University scientists has created a new synthetic biology approach, or a “QR code for cancer cells,” to follow tumor cells over time, finding there are meaningful differences in why a cancer cell dies or survives in response to anti-cancer therapies.

Remarkably, what fate cancer cells choose after months of therapy is “entirely predictable” based on seemingly small, yet important, differences that appear even before treatment begins. The researchers also discovered the reason is not genetics, contrary to beliefs held in the field.

The findings were recently published in Nature.

The study outlined the team’s new technology platform that developed a QR code for each of the millions of cells for scientists to find and use later — much like tagging swans in a pond. The QR code directs researchers to a genome-wide molecular makeup of these cells and provides information about how they’ve reacted to cancer treatment.

“We think this work stands to really change how we think about therapy resistance,” said Arjun Raj, co-senior author and Professor in Bioengineering in the School of Engineering and Applied Science at the University of Pennsylvania. “Rather than drug-resistant cells coming in just one flavor, we show that even in highly controlled conditions, different ‘flavors’ can emerge, raising the possibility that each of these flavors may need to be treated individually.”

In the study, the lab and collaborators sought to apply synthetic biology tools to answer a key question in cancer research: What makes certain tumors come back a few months or years after therapy? In other words, could the lab understand what causes some rare cells to develop therapeutic resistance to a drug?

“There are many ways cells become different from each other,” said Yogesh Goyal, the co-senior author at Northwestern University. “Our lab asks, how do individual cells make decisions? Understanding this in the context of cancer is all the more exciting because there’s a clinically relevant dichotomy: A cell dies or becomes resistant when faced with therapies.”

Using the interdisciplinary team, the scientists put the before-and-after cloned cells through a whole genome sequencing pipeline to compare the populations and found no systematic underlying genetic mutations to investigate the hypothesis. Raj and Goyal  helped develop the QR code framework, FateMap, that could identify each unique cell that seemed to develop resistance to drug therapy. “Fate” refers to whether a cell dies or survives (and if so, how), and the scientists “map” the cells across their lifespan, prior to and following anti-cancer therapy. FateMap is the result of work from several research institutions, and it applies an amalgamation of concepts spanning several disciplines, including synthetic biology, genome engineering, bioinformatics, machine learning and thermodynamics.

“Some are different by chance — just as not all leaves on a tree look the same — but we wanted to determine if that matters,” Goyal said. “The cell biology field has a hard time defining if differences have meaning.”

Penn Startup Vittoria Biotherapeutics Raises $10M in Seed Funding

Marco Ruella, MD

A Philadelphia life sciences company spun out of Penn is emerging from stealth mode with nearly $10 million from a seed funding round. Vittoria Biotherapeutics’ mission is to overcome limitations of CAR T cell therapy by using unique cell engineering and gene editing technologies to create new therapies that address unmet clinical needs. The technology the company is attempting to commercialize was developed by Marco Ruella, M.D., Assistant Professor of Medicine in the Perelman School of Medicine and member of the Penn Bioengineering Graduate Group, who is the company’s scientific founder.

Carl June Highlighted for Success in Gene Therapy

Carl June, MD

Scientific American recently featured two gene therapies that were invented at Penn, including research from Carl June, MD, the Richard W. Vague Professor in Immunotherapy in Pathology and Laboratory Medicine, director of the Center for Cellular Immunotherapies, and member of the Penn Bioengineering Graduate Group, which led to the FDA approval for the CAR T therapy (sold by Novartis as Kymriah) for treating acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.
