November 6th 2019: Crispr Takes Its First Steps in Editing Genes to Fight Cancer
Doctors have for the first time in the United States tested a powerful gene-editing technique in people with cancer.
The test, meant to assess only safety, was a step toward the ultimate goal of editing genes to help a patient’s own immune system to attack cancer. The editing was done by the DNA-snipping tool Crispr.
The procedure was feasible and safe, early results indicate, but whether it is fighting the disease is unclear. Only three patients have been treated so far, and the longest follow-up is nine months. All three patients are in their 60s, with very advanced cancers that had progressed despite standard treatments like surgery, radiation and chemotherapy.
“The good news is that all of them are alive,” said Dr. Edward A. Stadtmauer, the section chief of hematologic malignancies at the University of Pennsylvania Abramson Cancer Center. He added, “The best response we’ve seen so far is stabilization of their disease.”
The research was paid for by the Parker Institute for Cancer Immunotherapy and the company Tmunity. Some members of the research team, but not Dr. Stadtmauer, are equity holders in Tmunity, as is the University of Pennsylvania.
The findings have not yet been published in a medical journal, but will be presented next month at a meeting of the American Society of Hematology, and posted online on Wednesday.

March 5th 2019: Penn Researchers Receive Three of Ten National Clinical Research Achievement Awards
PHILADELPHIA—Three researchers from the Perelman School of Medicine at the University of Pennsylvania are among the recipients of the 2019 Clinical Research Achievement Awards from the Clinical Research Forum, which recognizes the ten most outstanding clinical research accomplishments in the United States during the preceding twelve months.
Researchers from all ten winning studies will be recognized at a dinner and reception at the National Press Club on March 5th in Washington, D.C. The Penn awardees are Lindsey A. George, MD, an assistant professor of Pediatrics at Penn and an attending physician in the division of Hematology at Children's Hospital of Philadelphia, for the first gene therapy trial to report a clinical cure for hemophilia B patients; Courtney A. Schreiber, MD, an associate professor of Obstetrics and Gynecology, for the only randomized clinical trial to date to test the efficacy of miscarriage management medications; and Joseph A. Fraietta, PhD, an assistant professor of Microbiology, for a study predicting the response of patients with chronic lymphocytic leukemia to chimeric antigen receptor (CAR) T cell therapy.
October 22nd 2018: Abramson Cancer Center Receives $10.7 Million to Study CAR T Cells in Solid Tumors
PHILADELPHIA – A new program project grant from the National Cancer Institute (NCI) will fund research by the Translational Center of Excellence for Lung Cancer Immunology at the Abramson Cancer Center of the University of Pennsylvania to improve the effectiveness of chimeric antigen receptor (CAR) T cell therapy at fighting solid tumors. Specifically, the program will evaluate approaches in lung cancer and mesothelioma. The $10.7 million grant will support the research for the next five years.
“Although CAR T cells have been revolutionized the treatment of leukemia and bone marrow cancers, we have not yet had the same success in treating solid tumors like lung cancer,” said the principal investigator of the grant, Steven M. Albelda, MD, the William Maul Measey Professor of Medicine at Penn and a member of the Center for Cellular Immunotherapies in the Abramson Cancer Center. “The goal of this program project is to solve this problem, and we’re grateful to the NCI for supporting our efforts to expand this approach to more patients around the world.”
The overall grant will include three interrelated projects, all of which will focus on exploring the ability of CAR T cells to stimulate other immune cells like dendritic cells and T cells to respond against the tumor – known the “bystander effect” – in non-small cell lung cancer (NSCLC) and malignant pleural mesothelioma (MPM).
The first project is a clinical trial with newly designed, highly potent anti-mesothelin CAR T cells. This project will also include a future trial to evaluate the safety and activity of CAR T cells engineered to engage the tumor “support structure” by targeting a protein called fibroblast activation protein (FAP), which is present on the supportive fibroblasts in the tumor. The results of the first two trials will also be used to design a third trial in the future, which will also be supported by this grant. Initial trials were conducted in collaboration with Novartis, but future trials with the anti-mesothelin CAR T cells will be conducted solely by Penn.
The second project will involve tracking CAR T cells and their effects in patients. It will attempt to answer the question of how long these CAR T cells persist and where they go, as well as whether they can activate other T cell responses.
The third project will study ways to improve the effectiveness of CARs in animal models. Since not all the tumor cells will have the target of the CARs, it will be important to find ways to trigger a patient’s own immune system to also attack the tumor cells the CARs will miss, another facet of the “bystander effect”. This project will also explore ways in which CARs can be combined with other therapies to enhance efficacy.
“The stakes of these projects are incredibly high. Achieving the success rates for CAR T therapy in solid tumors that we’ve already seen in leukemia and lymphoma would be a major paradigm shift in the treatment of these cancers,” Albelda said.
Other Penn researchers involved in this project include Charu Aggarwal, Beatriz Carreno, Andrew R. Haas, Wei-Ting Hwang, Carl June, Simon Lacey, Corey Langer, Gerald Linette, Leslie Litzky, and Ellen Puré.Penn Medicine Press Release
October 1st 2018: Penn Discovers New, Rare Mechanism for ALL to Relapse after CAR T Cell Therapy
PHILADELPHIA – A single leukemia cell, unknowingly engineered with the leukemia-targeting chimeric antigen receptor (CAR) lentivirus and infused back into a patient, was able to reproduce and cause a deadly recurrence of pediatric B-cell acute lymphoblastic leukemia (ALL).
New research from the Abramson Cancer Center of the University of Pennsylvania found that in one patient, the CAR lentivirus that would usually enter a T cell to teach it to hunt cancer also ended up binding with a leukemic cell. The presence of the CAR on the leukemic cell may have given that cell the ability to hide from the therapy by masking CD19, the protein that CARs target to kill cancer. Leukemic cells without CD19 are resistant to CAR T therapy, so this single cell led to the patient’s relapse. Nature Medicine published the findings today.
Penn co-authors of this study include Jun Xu, Joseph A. Fraietta, Tyler J. Reich, David E. Ambrose, Michael Klichinsky, Olga Shestova, Prachi R. Patel, Irina Kulikovskaya, Farzana Nazimuddin, Vijay G. Bhoj, Bruce L. Levine, Christopher L. Nobles, Frederic D. Bushman, Regina M. Young, John Scholler, Saar I. Gill, Carl H. June, and Simon F.

May 30th 2018: Nature Article from PDCS: Disruption of TET2 promotes the therapeutic efficacy of CD19-targeted T cells
"The receptor, known as a chimaeric antigen receptors (CAR), directs the engineered cell, called a CAR T cell, to the patient’s tumour when the cell is transferred back into the body. This therapy can be highly effective for tumours that express the protein CD19, such as B-cell acute leukaemias and large-cell lymphomas. However, some people do not respond to CAR T cells, and efforts to optimize this therapy are ongoing. In a paper in Nature, Fraietta et al. report the fortuitous identification of a gene that positively affected one person’s response to treatment with CAR T cells."

April 30th 2018: T Cell Biomarker Predicts Which CLL Patients Will Respond to CAR T Cell Therapy
Penn study suggests response may depend on quality of patients’ existing T cells before infusion
PHILADELPHIA – Penn Medicine researchers may have found the reason why some patients with advanced chronic lymphocytic leukemia (CLL) don’t respond to chimeric antigen receptor (CAR) T cell therapy, and the answer is tied to how primed patients’ immune systems are before the therapy is administered. While 80 percent of patients with advanced acute lymphoblastic leukemia (ALL) treated with the CAR T cell therapy now known as Kymriah™ have a dramatic response, only 26 percent of CLL patients respond to it in clinical trials. A new study from the Abramson Cancer Center of the University of Pennsylvania, published today in Nature Medicine, shows that CLL patients possessing a subset of vital, healthier T cells prior to CAR T cell therapy had a partial or complete clinical response to the treatment, while those lacking enough of those T cells did not respond. These healthier “early memory” T cells were marked by the expression of CD8 and CD27, as well as the absence of CD45RO. The findings show the potential to improve responses by enhancing a patient’s immune cells with emerging cell manufacturing techniques before CAR T cell therapy.
What’s more, the team – which was led by senior author J. Joseph Melenhorst, PhD and first author Joseph A. Fraietta, PhD, both faculty in the department of Pathology and Laboratory Medicine in Penn’s Perelman School of Medicine and of Penn’s Center for Cellular Immunotherapies, and included a multidisciplinary team from Penn and Novartis – also validated this signature in a separate, small group of patients and predicted with 100 percent accuracy who would experience complete remission.

PHILADELPIA October 21 2017:Carl June: The Cancer Slayer
The FDA just confirmed what we’ve known for years: Penn Medicine’s Carl June might be the most important doctor in the world.
Take a giant leap toward a cure for cancer, and everybody wants a piece of you.
On an afternoon in late August, two days before the U.S. Food and Drug Administration approved his laboratory’s game-changing treatment for leukemia, Carl June was being patted with face makeup so he could look his best in a video being shot by the University of Pennsylvania, his employer. Nobody knew exactly when the FDA decision was coming, or whether it would be good news. But the video team had an hour of June’s time, and they wanted to get some footage ready.
“Didn’t we say no lab coat?” the video director asked politely as June sat down in front of a window overlooking the Philly skyline.
“I was just told ‘coat.’ But I don’t care,” the doctor said.
“Are you okay with that?”
“Sure,” June said, starting to remove the coat.
“Do you usually wear your coat?”
He took off the coat.

Science Translational Medicine PublicationNew York Times Perspective article interviewing Dr. Stephan Grupp
A chimeric antigen receptor T-cell (CAR-T) therapy for glioblastoma (GBM) successfully crossed the blood–brain barrier to reach tumors in the brain, appeared safe, and reduced levels of its epidermal growth factor variant III (EGFRvIII) tumor target in GBM cells, in a first-in-man trial carried out by researchers at the University of Pennsylvania. The study also found that wide variation in EGFRvIII expression among patients, coupled with active immunosuppressive changes in the tumor in response to CAR T-cell infusion, may represent barriers to the clinical utility of the CAR-T therapy on its own.
The autologous EGFRvIII-directed CAR-T therapy has been developed through an ongoing collaboration between researchers at the University of Pennsylvania and Novartis. The partnership has already resulted in the development of Novartis’ CAR-T therapy CTL019 (tisagenlecleucel), which just last week was unanimously recommended for approval by FDA’s Oncologics Drug Advisory Committee for treating relapsed or refractory (r/r) acute lymphoblastic leukemia (ALL) in children and young adults.

Novartis AG's pioneering cancer drug won the backing of a federal advisory panel on Wednesday, paving the way for the first gene therapy to be approved in the United States.
An advisory panel to the Food and Drug Administration voted 10-0 that the drug, tisagenlecleucel, should be approved to treat patients with relapsed B-cell acute lymphoblastic leukemia (ALL), the most common form of U.S. childhood cancer.
The FDA is not obliged to follow the recommendations of its advisers but typically does so. The agency is expected to rule on the drug by the end of September.
PHILADELPHIA July 11th 2017:First gene therapy — ‘a true living drug’ — on the cusp of FDA approval
An FDA advisory committee will decide Wednesday whether to recommend approval of the approach, which uses patients’ own genetically altered immune cells to fight blood cancers.
When doctors saw the report on Bill Ludwig’s bone-marrow biopsy, they thought it was a mistake and ordered the test repeated. But the results came back the same: His lethal leukemia had been wiped out by an experimental treatment never used in humans.
“We were hoping for a little improvement,” remembers the 72-year-old retired New Jersey corrections officer, who had battled the disease for a decade. He and his oncologist both broke down when she delivered the good news in 2010. “Nobody was hoping for zero cancer.”
The pioneering therapy with Ludwig and a few other adults at the University of Pennsylvania hospital paved the way for clinical trials with children. Six-year-old Emily Whitehead, who was near death, became the first pediatric recipient in 2012. Like Ludwig, she remains cancer-free.
Such results are why the treatment is on track to become the first gene therapy approved by the Food and Drug Administration. An FDA advisory committee will decide Wednesday whether to recommend approval of the approach, which uses patients’ own genetically altered immune cells to fight blood cancers.
If the panel gives the nod, the agency probably will follow suit by the end of September. That would open the latest chapter in immunotherapy — “a true living drug,” says Penn scientist Carl June, who led its development.

PHILADELPHIA May 31th 2017: Personalized Cell Therapy Combined with Ibrutinib Achieves Complete Remission in High Percentage of Chronic Lymphocytic Leukemia Patients
Latest results from University of Pennsylvania trial investigating CAR Therapy to Treat CLL
Combining the kinase inhibitor ibrutinib with an investigational personalized cellular therapy known as CTL119 can lead to complete remission in patients with high-risk chronic lymphocytic leukemia (CLL), according to new research from the Perelman School of Medicine at the University of Pennsylvania and Penn’s Abramson Cancer Center (ACC). The team will present the results from its pilot study of this combination therapy during the 2017 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract # 193355).
The team will present on the first 10 patients in the trial, each of whom had been taking ibrutinib for at least six months but had not achieved a complete remission. They were then infused with their own engineered “hunter” T cells. Eight of nine patients who are evaluable for response had no evidence of disease in their bone marrow at three months, and all remain in remission after a median follow-up period of six months, with a range from 0.5 to 9 months. One patient was found to have a partial response in their marrow.
The research team is led by Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine and director of Translational Research in the ACC, along with David Porter, MD, the Jodi Fisher Horowitz Professor in Leukemia Care Excellence and director of Blood and Marrow Transplantation in the ACC.

WASHINGTON DC, May 13th 2017: PDCS Abstract Chosen for Clinical Trials Spotlight Symposium at American Society of Gene & Cell Therapy Meeting
TET2 Gene Disruption via Lentiviral Integration Promotes CAR T Cell Expansion and
“The immune system has a number of ways to fight leukemia, one of which is T cells. A common reason for failure of the immune system to eliminate tumor cells is that it does not recognize and kill “self” cancer cells. Though the T cells may still be fully functional, cancer cells are no longer recognized by the immune system as “unwanted”, causing cancer cells to win the arms race. It is now possible to use gene engineering to introduce molecules, such as chimeric antigen receptors, or “CARs” into T cells allowing them to target and attack a patient’s own cancer.
In some cancers, however, war weary T cells even when endowed with new weapons for tumor mass destruction (CARS), cannot expand their numbers to mount a robust
response. Researchers at the University of Pennsylvania recently uncovered the linchpin
responsible for the elaboration of a strong and effective attack. With their approach, the T-cell
genome is modified by integration of the CARs that direct tumor cell recognition and killing.
During the genetic engineering process in one patient with chronic lymphocytic leukemia, the CAR landed in a genomic hotspot, disrupting a critical gene, Tet2. This event resulted in remodeling of DNA structure and allowed a single “super soldier” T cell to clone itself into a massive battalion that completely eradicated the patient’s cancer. Upon completion of its mission, the army of immune cells stood down, leaving a troop of sentinels behind in case the
invader returns. Over 4-years later, the patient remains cancer-free. Thus, while battling cancer
often relies on “strike hard and often” strategies, a careful tempering and appropriate deployment of specific immune cells is needed to win the war.” says

SAN DIEGO, Dec. 05, 2016: CAR T cell immunotherapy continues to yield complete responses in leukemia
A highly innovative, personalized cell-based treatment for a high-risk form of the most common childhood cancer continues to move through clinical trials. Pediatric oncologists from Children's Hospital of Philadelphia (CHOP) today reported new results using T cell immunotherapy against relapsed or refractory acute lymphoblastic leukemia (ALL).
The physician-scientists presented findings at the annual meeting of the American Society of Hematology today in San Diego.
This immunotherapy modifies a patient's own immune T cells, extracted and engineered to potentially seek and destroy the patient's leukemia cells. The CHOP researchers reported on the first global, multicenter clinical trial of these cells and on a separate single-center trial, the first to use a version of these cells carrying a "humanized" protein more similar to human proteins.
In both trials, the patients were children and young adults who had relapsed after previous leukemia therapies, and/or had persistent (refractory) disease.
CHOP pediatric oncologist Stephan A. Grupp, MD, PhD, director of CHOP's Cancer Immunotherapy Frontier Program, co-moderated the ASH session on advances in immunotherapy for ALL at which these findings were presented. At this session, he reported results from the first global, multicenter trial of chimeric antigen receptor (CAR) T cells, of which he is the lead investigator.
This study, sponsored by Novartis, is a global registration trial—one that will provide data to submit to the U.S. Food and Drug Administration (FDA), requesting approval for clinical use. It has enrolled 81 patients at 25 centers in the U.S., Canada, Europe, Japan and Australia. Among the 50 patients who have received a single dose of the T cells, designated CTL019 cells, 41 patients (82 percent) had a complete response (that is, no detectable leukemia cells) within one to three months after treatment.
PHILADELPHIA, November 26, 2016: New tricks in canine cancer research may improve treatments for humans, too
“Genetically, you are a lot more like your dog than that mouse running around a cage in the lab,” said Nicola Mason, a veterinarian and immunologist who oversees the vaccine and several other canine trials at Penn’s School of Veterinary Medicine. “Where dogs really stand out is in the way they generate tumors and react to treatments, which is a lot like people.”
Most cancer drugs for dogs were developed first for humans. Take Harley, a striking 4-year-old black boxer with aggressive leukemia. He recently came to Penn for a treatment called CAR T-cell therapy, which has shown some promising results in trials for people with blood cancers. The immunotherapy procedure for dogs is similar to the human one: T cells, a key component of the immune system, are extracted, genetically modified in the lab to bolster their cancer-killing abilities, increased in number and then reinfused.
Mason began working on the treatment for dogs when she was a postdoctoral fellow in the lab of Carl June, a prominent researcher at Penn’s Perelman School of Medicine and a CAR T-cell pioneer. She consults with him frequently.
Owners of dogs in the Penn Vet trials get much of the care free, including treatments and follow-up visits. But there can be related expenses. In the osteosarcoma trial, owners are required to pay for the amputation and chemo.
PHILADELPHIA, November 17, 2016: Genetically Engineered T Cells Render HIV's Harpoon Powerless
Penn Team to Test "Broader, More Potent" Peptide Approach in HIV Patients
When HIV attacks a T cell, it attaches itself to the cell’s surface and launches a “harpoon” to create an opening to enter and infect the cells. To stop the invasion, researchers from the Penn Center for AIDS Research at the University of Pennsylvania and scientists from Sangamo BioSciences, Inc. have developed genetically engineered T cells armed with a so-called “fusion inhibitor” to disrupt this critical step and prevent a wide range of HIV viruses from entering and infecting the T cells. The findings were reported today online in a preclinical study in PLOS Pathogens.
HIV medicine experienced a breakthrough in the early 2000s with a unique class of drugs known as “fusion inhibitors.” Unlike most drugs that block virus replication inside of T cells, these drugs prevent HIV from entering cells in the first place. The drug, enfuvirtide, modeled after a peptide from the viral envelope and used today in combination with other antiretroviral therapies, has been shown to keep the virus at bay. However, patients need to inject enfuvirtide daily under their skin, limiting its utility and acceptability to patients, especially when compared to many other orally available drugs. HIV can also become resistant to enfuvirtide.
Building on this approach with a powerful genetic technique, researchers developed a novel way to deliver the fusion inhibitor peptide precisely to the spot on the cell surface where the virus attaches and launches its envelope, like a harpoon. The team genetically altered T cells by introducing a so-called C34 peptide, modeled after enfuvirtide, directly onto receptors, CXCR4 and CCR5, which are crucial for HIV entry. By using these molecules to deliver the C34 peptide to the site where the virus enters, these investigators showed that HIV was potently inhibited and that this inhibition extended to genetically diverse HIVs, including those that were resistant to the drug, enfuvirtide.
The most impressive results were seen when the C34 peptide was attached to CXCR4, where the Penn investigators showed that T cells expressing this molecule were protected in a mouse model of HIV infection.
“We believe that our approach to precisely target an inhibitory drug to the site of viral entry creates a new way to engineer human T cells to become resistant to HIV infection,” said senior author James Hoxie, MD, a professor of Medicine in the division of Hematology/Oncology in the Perelman School of Medicine at the University of Pennsylvania. “It’s potent and very broad. Every strain of HIV we tried was sensitive to it, regardless of whether the virus used CCR5 or CXCR4, which is a big advantage, since HIV typically uses CCR5 to establish infection, but can over time, evolve to use a CXCR4 instead. With this approach, it doesn’t matter where the virus came from or what cellular molecule it needs to infect cells.”
The findings set the stage for an upcoming phase I clinical trial in HIV-positive patients to determine the safety and appropriate dosage of a patient’s own T cells engineered to express the C34-CXCR4 molecule, as well as to demonstrate their ability to resist infection when antiretroviral therapy is interrupted.
The clinical trial investigating the work with C34 is slated to start in December 2016. The researchers will infuse C34-CXCR4 expressing T cells into well-controlled HIV-infected individuals. It will be a dose-escalation study in which 1, 3, or 10 billion engineered T cells will be infused. After infusion, an “analytical treatment interruption” will occur for about 16 weeks and time to viral rebound and enrichment for the C34-CXCR4 expressing cells will be monitored. At present, patients infected with HIV must continue to take anti-HIV drugs to prevent the virus from replicating and causing disease. Efforts are underway at Penn and throughout the world to develop strategies that will enable drug therapy for HIV to be discontinued safely.
PHILADELPHIA, PA, October 25, 2016: Tech giant Sean Parker launches Penn's cancer immunotherapy center
Billionaire tech guru Sean Parker told an audience at the University of Pennsylvania on Tuesday that he wants to bring hacker culture to the field of immunotherapy.
But he wasn’t talking about computer geeks waging malicious cyberattacks.
“The term hacker has a different connotation for me,” said Parker, a self-described “hacker-philanthropist.” “It has to do with finding creative, novel solutions to problems.”
Parker’s remarks were part of a panel presentation celebrating the official launch of Penn’s participation in the Sean Parker Institute for Cancer Immunotherapy.
The panel, featuring top Penn scientists and leaders, was moderated by pediatrician Richard Besser, who is ABC News’ chief medical editor (and a Penn Medical School graduate).
Parker’s new institute -- announced in April, along with $250 million in funding from his foundation -- aims to accelerate the development of revolutionary cancer therapies by uniting Penn with five other leading research centers: Memorial Sloan-Kettering Cancer Center; Stanford Medicine; the University of California, Los Angeles; the University of California, San Francisco; and the University of Texas MD Anderson Cancer Center. The institute links more than 300 researchers, all devoted to immunotherapy — harnessing the immune system to fight cancer.
WASHINGTON, DC, June 21, 2016: First proposed human test of CRISPR passes initial safety review
A cancer study that would represent the first use of the red-hot gene-editing tool CRISPR in people passed a key safety review today. The proposed clinical trial, in which researchers would use CRISPR to engineer immune cells to fight cancer, won approval from the Recombinant DNA Advisory Committee (RAC) at the U.S. National Institutes of Health, a panel that has traditionally vetted the safety and ethics of gene therapy trials funded by the U.S. government and others.
Although other forms of gene editing have already been used to treat disease in people, the CRISPR trial would break new ground by modifying three different sites in the genome at once, which has not been easy to do until now. The study has also grabbed attention because—as first reported by the MIT Technology Review—tech entrepreneur Sean Parker’s new $250 million Parker Institute for Cancer Immunotherapy will fund the trial.
The proposed CRISPR trial builds off the pioneering efforts of Carl June and others at University of Pennsylvania (UPenn) to genetically modify a cancer patient’s own immune cells, specifically a class known as T cells, to treat leukemia and other cancers. For the CRISPR trial, a UPenn-led team wants to remove T cells from patients and use a harmless virus to give the cells a receptor for NY-ESO-1, a protein that is often present on certain tumors but not on most healthy cells. The modified T cells are then reinfused back into a patient and, if all goes well, attack the person’s NY-ESO-1–displaying tumors. The UPenn team has already tested this strategy in a small clinical trial for multiple myeloma. But although most patients’ tumors initially shrank, the reintroduced T cells eventually became less effective and stopped proliferating.
To boost the staying power of the engineered T cells, the UPenn group wants to use CRISPR to disrupt the gene for a protein called PD-1. The protein sits on the surface of T cells and helps dampen the activity of the cells after an immune response, but tumors have found ways to hide from T cell attack by flipping on the PD-1 switch themselves. (Drugs that block PD-1 eliminate this immune suppression and have proven to be a promising immunotherapy cancer treatment.)
June’s team also wants to knock out two gene segments that encode different portions of the protein that makes up a T cell’s primary receptor so that the engineered NS-ESO-1 receptor will be more effective. To do this, they will introduce into the T cells so-called guide RNAs, which tell CRISPR’s DNA-snipping enzyme, Cas9, where to cut the genome.
The 2-year trial will treat 18 people with myeloma, sarcoma, or melanoma who have stopped responding to existing treatments at three sites that are members of the Parker Institute—UPenn; the University of California, San Francisco; and the University of Texas MD Anderson Cancer Center in Houston.
LOS ANGELES, April 13, 2016: University of Pennsylvania to Join First-of-its-Kind Research Collaboration to Fight Cancer with New Immunotherapies
$250 Million Grant to Launch Parker Institute for Cancer Immunotherapy Poised to Accelerate New Discoveries and Treatments
The University of Pennsylvania has joined an unprecedented cancer research effort, the Parker Institute for Cancer Immunotherapy, which unites six of the nation’s top medical schools and cancer centers around a shared aim of accelerating breakthrough immunotherapy research that will turn more cancers into a curable disease.
The venture is backed by a $250 million gift from the Parker Foundation, making it the largest single contribution ever made to the field of immunotherapy. The Parker Foundation was founded by Sean Parker in June 2015 with a $600 million gift to spur innovations in the life sciences, global public health, and civic engagement.
“We are tremendously excited to join this collaboration, which will allow us to investigate promising new immunotherapy avenues for the treatment of cancer outside of our institutional silos in very unique ways,” said the Parker Institute’s Penn director, Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in the Perelman School of Medicine and director of Translational Research in the Abramson Cancer Center.“Working together will enable us to make quicker progress as we work to translate our laboratory findings into clinical trials.”
Initial funding of $10 to 15 million has been awarded to set up the Parker Institute at Penn. This investment will continue to grow on an annual basis via additional project grants, shared resources and central funding.The funding will support laboratory studies and clinical trials, recruitment of talented new faculty, and support for early-career investigators who will train at Penn. The effort will augment Penn’s longstanding commitment to cancer research. In 2015, more than 10,000 patients participated in Abramson Cancer Center clinical trials. Nearly 1,100 trials are currently underway, 80 of which are immunotherapy studies.

September 9th 2015: Penn Researchers Report Sustained Remission After Treatment with Investigational Personalized Cellular Therapy In Patient with Multiple Myeloma
New Treatment Combination with CTL019 Targets Precursors of Cancerous White Blood Cells
LINK PHILADELPHIA New Treatment Combination with CTL019 Targets Precursors of Cancerous White Blood Cells
– A multiple myeloma patient whose cancer had stopped responding after nine different treatment regimens experienced a complete remission after receiving an investigational personalized cellular therapy known as CTL019 developed by a team at the University of Pennsylvania. The investigational treatment was combined with chemotherapy and an autologous stem cell transplant – a new strategy designed to target and kill the cells that give rise to myeloma cells.
The team’s findings are published in a case report today in the New England Journal of Medicine. Prior to receiving the therapy, the patient had already received nine different therapy regimens in the five years since her diagnosis, including a previous autologous stem cell transplant, which had only controlled her disease for a few months. Her bone marrow was almost entirely filled by cancerous cells when she entered the study. By 130 days after receiving the infusion of engineered cells, tests revealed no evidence of disease. The patient – who was the first to be treated as part of this trial – remains in remission more than 12 months after receiving this therapy.
September 2nd 2015: Abramson Cancer Center Researchers Report Long-Term Remissions in First Group of Patients to Receive Personalized Cellular Therapy for Chronic Lymphocytic Leukemia
‘Penn Study Details Emerging Field's Most Mature Findings'
LINK PHILADELPHIA – Eight of 14 patients in the first trial of the University of Pennsylvania’s personalized cellular therapy for chronic lymphocytic leukemia (CLL) responded to the therapy, with some complete remissions continuing past four and a half years. These results, published today in Science Translational Medicine, represent the most mature data from clinical trials of an approach known as CTL019, developed by a team from Penn’s Abramson Cancer Center and the Perelman School of Medicine.
In 2011, the research team published initial findings from the first three patients to enroll in the trial. Two of those patients had complete responses, and their leukemia remains in remission today, more than four and a half years after receiving the therapy. The first patient to receive the therapy recently marked five years cancer-free.
“The durability of the remissions we have observed in this study are remarkable and have given us great hope that personalized cell therapies are going to be important options for patients whose cancers are no longer treatable with standard approaches,” said lead author David L. Porter, MD, the Jodi Fisher Horowitz Professor in Leukemia Care Excellence and director of Blood and Marrow Transplantation in Penn’s Abramson Cancer Center. “The patients in this study are pioneers, whose participation has given us a foundation of knowledge and experience on which to build this new approach to help more patients.”
The new study details the completed, 14-patient pilot trial of CTL019 for CLL, which began in the summer of 2010. The overall response rate was 57 percent. All patients who received the experimental therapy, which is made from their own immune cells, had cancer that had relapsed or continued to progress after receiving multiple conventional Food and Drug Administration-approved therapies, and few were eligible for bone marrow transplants.
July 20th 2015: Investigational T-cell Receptor Therapy Achieves Encouraging Clinical Responses in Multiple Myeloma Patients, Penn-led Study Finds
‘NY-ESO T cell receptor therapy found to be safe, with no cytokine release syndrome cases; engineered cells persisted in most patients for up to two years after infusion'
LINK PHILADELPHIA – Results from a clinical trial investigating a new T cell receptor (TCR) therapy that uses a person’s own immune system to recognize and destroy cancer cells demonstrated a clinical response in 80 percent of multiple myeloma patients with advanced disease after undergoing autologous stem cell transplants (ASCT). This time, researchers modified T cells to attack cancer cells expressing NY-ESO-1, an antigen found in nearly 60 percent of multiple myelomas and previously shown to be associated with tumor growth and poor prognosis.
The results of the study were published this week in the journal Nature Medicine from researchers at Penn’s Abramson Cancer Center, including senior author Carl H. June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine and director of Translational Research in the ACC, the University of Maryland School of Medicine, and Adaptimmune Therapeutics plc (Adaptimmune).
In the phase I/II clinical trial of 20 patients, the engineered cells were deemed safe, trafficked to the site of the tumor (bone marrow), and persisted in 90 percent of the patients who reached two years follow up after infusion, the research team found. Significant anti-tumor activity was observed as well: nearly 70 percent had a near complete or complete response within three months post treatment, which compares favorably with the expected responses (less than 40 percent) in patients without high-risk disease following an ASCT.
This is the first published report of lentiviral vector mediated TCR therapy that has shown persistence beyond one month, June said. “This study shows us that these TCR specific T cells are safe and feasible in patients expressing NY-ESO-1,” he said. “But it also revealed encouraging anti-tumor activity and showed impressive durable T cell persistence.”
Penn co-authors include Bruce L. Levine, Don L. Siegel, Naseem Kerr, Minnal Gupta, Irina Kulikovskaya, Jeffrey Kinklestein, Brendan Weiss, Alfred Garfall, Simon F. Lacey, and Dan T. Vogl.
June 17th 2015: CTL019 Shows Early Promise in Multiple Myeloma
CTL019, a breakthrough CD19-targeted chimeric antigen receptor (CAR) T-cell therapy, demonstrated intriguing antitumor activity in a small study of patients with refractory multiple myeloma, including those with heavily pretreated disease, according to data presented at the 2015 ASCO Annual Meeting and again at the 20th EHA Congress.
In the small 5-patient study, all but 1 patient responded to treatment with CTL019, which included 1 stringent complete response (sCR) with MRD-negativity at a 339-day follow-up. Other responses included a partial response (PR) and a very good PR (VGPR). One patient experienced an unconfirmed CR with MRD-positivity; however, this patient progressed after 6 months. "These early results suggest that CTL019 and autologous transplant in patients with myeloma is safe and feasible," lead author Alfred L. Garfall, MD, from the Abramson Cancer Center at the University of Pennsylvania, said during his presentation. "We saw evidence of clinical benefit in 3 of 4 patients with greater than 100 days of follow-up."

LINK Episode Three: Finding the Achilles Heel (Wednesday, April 1, 2015/9-11PM ET)
This episode picks up the story at another moment of buoyant optimism in the cancer world: Scientists believe they have cracked the essential mystery of the malignant cell and the first targeted therapies have been developed, with the promise of many more to follow. But very quickly cancer reveals new layers of complexity and a formidable array of unforeseen defenses. In the disappointment that follows, many call for a new focus on prevention and early detection as the most promising fronts in the war on cancer. But other scientists are undeterred, and by the second decade of the 2000s their work pays off. The bewildering complexity of the cancer cell, so recently considered unassailable, yields to a more ordered picture, revealing new vulnerabilities and avenues of attack. Perhaps most exciting of all is the prospect of harnessing the human immune system to defeat cancer. This episode includes patients Doug Rogers, a 60-year-old NASCAR mechanic with melanoma, and Emily Whitehead, a six-year-old child afflicted with leukemia. Each is a pioneer in new immunotherapy treatments, which the documentary follows as their stories unfold. Both see their advanced cancers recede and are able to resume normal lives.
March 2015: VICE Special Report: 'Killing Cancer'
‘My life, like most people's, has been negatively affected by cancer, and the thought of my young children living in an age where this is no longer humanity's No. 1 health fear was simply overpowering.
- Shane Smith'
LINK Cancer has been such a scourge of humanity for so long that the very word inspires a deep dread in anyone who hears it—it's a two-syllable gut punch, a hole that suddenly opens up beneath you. Similarly, a "cure for cancer" has been a holy grail of modern medical research the way getting to the moon used to inspire space programs. All told, the world has spent decades and billions of dollars trying to cure cancer, or cure some kinds of it, or simply make some of them less awful and deadly—and VICE is going to give viewers an inside look at the most cutting-edge cancer treatments in the world.

December 2014: Watch A Man Tell How Killer T-Cells Eradicated His Cancer
‘There's probably not a hotter area of biotechnology right now than what's known as CART therapy, in which a patient's own white blood cells are genetically engineered to attack cancer.'
LINK Matthew Herper, staff writer, FORBES– All this excitement is over a complicated and some might say cumbersome therapy. CART stands for chimeric antigen receptor T-cell; these immune cells are removed from the patient’s body, and a genetically engineered receptor is added that teaches the cells to kill cancer cells. Then the cells are infused back in, often causing severe and sometimes deadly side effects as the body’s immune system goes into overdrive. Right now, the positive results are all from CARTs that are designed to kill B cells expressing CD19, which are the cells that go wrong in many types of cancer. Patients can live without B cells, but to take on other cancers, the CARTs are going to need to stop killing at some point, or kill only cancer cells. But none of that gets across the reason that there’s so much excitement. What does? Well the video I’ve put in this post. This is a patient named Douglas Olson, a long-time healthcare industry consultant. I met him while reporting a cover story on CART therapy earlier this year. Doug was the second patient to receive CART cells at the University of Pennsylvania; this was the program later licensed by Novartis. He’s now been cancer-free and healthy for four years. (The eyepatch is temporary, due to a detached retina, and is not related to the CART treatment.) Want to understand why people are crazy excited about this new treatment? Listen to Doug.
The video is taken from the third annual Forbes Healthcare Summit, which was held on Dec. 8 and Dec. 9, 2014.

September 11th 2014 Center for Advanced Cellular Therapeutics to Rise on Penn Medicine Campus:
‘New Facility Poised to Accelerate the Research and Development of Personalized Cellular Cancer Therapies'
LINK PHILADELPHIA — A University of The University of Pennsylvania today reached an important milestone in its alliance with Novartis as it unveiled plans for the construction of a first-of-its-kind Center for Advanced Cellular Therapeutics (CACT) on the Penn Medicine campus in Philadelphia. The CACT will become the epicenter for research using Chimeric Antigen Receptor technology (CAR), which enables a patient’s T cells to be reprogrammed outside of the body so when they are re-infused into the patient, the T cells have the ability to “hunt” and destroy the cancer cells. Clinical trials using this approach have made headlines around the world.
Plans for the 30,000-square foot facility cement the Penn-Novartis alliance, a marquee component of Penn's efforts in translational sciences that expedite the development of novel therapies for diseases of all kinds. The collaboration was announced in August 2012, when the two organizations entered an exclusive global research and licensing agreement to further study and commercialize novel CAR therapies.
The CACT, which will be funded in part through a $20 million investment from Novartis, will be devoted to the discovery, development and manufacturing of these personalized cellular cancer therapies, through a joint research and development program led by scientists and clinicians from Penn and Novartis.

This award is the first of its kind offered by the Society. Congratulations Dr. Ruella!
Dr. Ruella was selected as the winner of this award for his project, titled, “Dual Chimeric Antigen Receptor T Cell Therapy for Human B-Cell Acute Lymphoblastic Leukemia.”
“I’m very honored to be the first recipient of this fellowship award and I would like to thank the Society and the award committee for choosing my project,” said Dr. Ruella. “The goal of my research project is to treat patients with relapsing or refractory B-cell Leukemia with Chimeric Antigen Receptor T cells targeting multiple antigens, in order to avoid tumor escape. As powerful new therapies are developed that enhance the immune response to malignancy, it will be important for us to stay ahead of cancer’s escape mechanisms. One way to do this is with combination therapies.”
This year’s award was established through the generosity of EMD-Serono and is intended to support the development of the next generation of immunotherapy experts. Through this funding of novel research, the Society intends to cultivate those individuals who have a vested interest in furthering the clinical research and translation of cancer immunotherapy.
July 7th 2014 University of Pennsylvania's Personalized Cellular Therapy for Leukemia Receives FDA's Breakthrough Therapy Designation:
‘Engineered Cells Known As CTL019 Are the First Therapy of Their Kind to Obtain Designation'
PHILADELPHIA — A University of Pennsylvania-developed personalized immunotherapy has been awarded the U.S. Food and Drug Administration’s Breakthrough Therapy designation for the treatment of relapsed and refractory adult and pediatric acute lymphoblastic leukemia (ALL). The investigational therapy, known as CTL019, is the first personalized cellular therapy for the treatment of cancer to receive this important classification.
In early-stage clinical trials at the Hospital of the University of Pennsylvania and the Children’s Hospital of Philadelphia, 89 percent of ALL patients who were not responding to conventional therapies went into complete remission after receiving CTL019.
“Our early findings reveal tremendous promise for a desperate group of patients, many of whom have been able to return to their normal lives at school and work after receiving this new, personalized immunotherapy,” said the Penn research team’s leader, Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in the Perelman School of Medicine and director of Translational Research in the Abramson Cancer Center of the University of Pennsylvania. “Receiving the FDA’s Breakthrough Designation is an essential step in our work with Novartis to expand this therapy to patients across the world who desperately need new options to help them fight this disease.”
The FDA’s Breakthrough Therapy designation, created in 2012, is intended to expedite the development and review of new medicines – both drugs and biologic agents – that treat serious or life-threatening conditions, if the therapy has demonstrated substantial improvement over available therapies. The FDA has previously granted Breakthrough Therapy to only four other biologic agents.
