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, MD, Professor in the Perelman School of Medicine and member of the Penn Bioengineering Graduate Group, was quoted in a recent press release announcing a new international partnership between Penn Medicine (PSOM), the Children’s Hospital of Pennsylvania (CHOP), and Costa Rica’s CCSS, or the Caja Costarricense de Seguro Social (Social Security Program), to develop CAR T research in Costa Rica. June is a world renowned cancer cell therapy pioneer whose research led to the initial development and FDA approval of CAR T cell therapy:
“‘At least 15,000 patients across the world have received CAR T cells, and dozens more clinical trials using this approach are in progress, for almost every major tumor type, but people in many parts of the globe still do not have access to treatment with these transformative therapies,’ said Carl H. June, MD, the Richard W. Vague Professor in Immunotherapy and director of the Center for Cellular Immunotherapies in Penn’s Perelman School of Medicine. “We are honored to work with our colleagues in Costa Rica in hopes of building a path for patients in underserved areas to have the opportunity to benefit from clinical research programs offering this personalized therapy.’”
The U.S. Food and Drug Administration has expanded its approval for Kymriah, a personalized cellular therapy developed at the Abramson Cancer Center, this time for the treatment of adults with relapsed/refractory follicular lymphoma who have received at least two lines of systemic therapy. “Patients with follicular lymphoma who relapse or don’t respond to treatment have a poor prognosis and may face a series of treatment options without a meaningful, lasting response,” said Stephen J. Schuster, the Robert and Margarita Louis-Dreyfus Professor in Chronic Lymphocytic Leukemia and Lymphoma in the Division of Hematology Oncology. It’s the third FDAapproval for the “living drug,” which was the first of its kind to be approved, in 2017, and remains the only CAR T cell therapy approved for both adult and pediatric patients.
“In just over a decade, we have moved from treating the very first patients with CAR T cell therapy and seeing them live healthy lives beyond cancer to having three FDA-approved uses of these living drugs which have helped thousands of patients across the globe,” said Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in Penn’s Perelman School of Medicine and director of the Center for Cellular Immunotherapies in the Abramson Cancer Center and director of the Parker Institute for Cancer Immunotherapy at Penn. “Today’s news is new fuel for our work to define the future of cell therapy and set new standards in harnessing the immune system to treat cancer.”
Research from June, a member of the Penn Bioengineering Graduate Group, led to the initial 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.
A new feature in Chemistry World explores the history of CAR (chimeric antigen receptor)-T cell therapy, a revolutionary type of therapeutic treatment for certain types of cancer. One of the pioneers of CAR-T cell therapy is Carl June, Richard W. Vague Professor in Immunotherapy in the Perelman School of Medicine and member of the Penn Bioengineering Graduate Group. His groundbreaking research opened the door for FDA approval of the CAR T therapy called Kymriah, which treats acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.
Carl H. June, the Richard W. Vague Professor in Immunotherapy in Pathology and Laboratory Medicine at Penn Medicine, director of the Center for Cellular Immunotherapies and the Parker Institute for Cancer Immunotherapy, and member of the Penn Bioengineering Graduate Group at the University of Pennsylvania, has led a new analytical study published in Nature that explains the longest persistence of CAR T cell therapy recorded to date against chronic lymphocytic leukemia (CLL), and shows that the CAR T cells remained detectable at least a decade after infusion, with sustained remission in both patients. June’s pioneering work in gene therapy led to the FDA approval for the CAR T therapy (sold by Novartis as Kymriah) for treating leukemia and transforming the fight against cancer. His lab develops new forms of T cell based therapies.
From COVID vaccines to cancer immunotherapies to the potential for correcting developmental disorders in utero, mRNA-based approaches are a promising tool in the fight against a wide range of diseases. These treatments all depend on providing a patient’s cells with genetic instructions for custom proteins and other small molecules, meaning that getting those instructions inside the target cells is of critical importance.
The current delivery method of choice uses lipid nanoparticles (LNPs). Thanks to surfaces customized with binding and signaling molecules, they encapsulate mRNA sequences and smuggle them through the cell membrane. But with a practically unlimited number of variables in the makeup of those surfaces and molecules, figuring out how to design the most effective LNP is a fundamental challenge.
Now, in a study featured on the cover of the journal Nano Letters, researchers from the University of Pennsylvania’s School of Engineering and Applied Science and Perelman School of Medicine have now shown how to computationally optimize the design of these delivery vehicles.
Using an established methodology for comparing a wide range of variables known as “orthogonal design of experiments,” the researchers simultaneously tested 256 candidate LNPs. They found the frontrunner was three times better at delivering mRNA sequences into T cells than the current standard LNP formulation for mRNA delivery.
The study was led by Michael Mitchell, Skirkanich Assistant Professor of Innovation in the Department of Bioengineering in Penn’s School of Engineering and Applied Science, and Margaret Billingsley, a graduate student in his lab.

Title: “Multi-input Chemical Control with Computationally Designed Proteins for Research Tools and Cell Therapies”
Protein modules that are responsive to small molecule inputs have enabled control of cellular processes for decades’ worth of important mechanistic studies. More recently, they have gained attention as a means of control for improved safety of cellular therapies. To date, most small molecule-responsive systems have been adapted from natural proteins, which provide limited control behaviors and often rely on small molecules with non-ideal properties for use in humans. I will describe how we have used computational protein design to move beyond these naturally occurring systems to create a new set of molecular tools that are responsive to multiple clinically approved drugs. The unique architecture of our system enables more complex control behaviors for multiple cellular outputs. I will describe applications of this designed system in the control of mammalian cytoskeletal signaling, transcription, and CAR T-cell therapy.

Title: “High-throughput Screening of a Combinatorial CAR Co-stimulatory Domain Library”
CAR T cells—T cells engineered to express a chimeric antigen receptor that redirects their function to a specific antigen—have proven to be an effective therapy for certain B cell cancers, but many issues remain in order to apply CAR T cells to a broader range of cancers. The activity of CAR T cells can be modulated by varying their co-stimulatory domains. Most CARs use co-stimulatory domains from natural proteins such as 41BB or CD28, each of which contains motifs that recruit unique signaling molecules and elicit a corresponding T cell response. One strategy to achieve increased control over T cell function is to engineer synthetic co-stimulatory domains composed of novel combinations of motifs from natural co-stimulatory proteins. We constructed libraries of CARs containing synthetic co-stimulatory domains and screened these library in primary human T cells for the ability to promote proliferation, degranulation, and memory formation. The results of the screens give insights into how signaling motifs dictate cell function and offer clues on how to engineer co-stimulatory domains that promote desired CAR T cell functions.
