Novel cell therapy treatments offer promise to immune-compromised children

In a first-of-its-kind clinical trial, researchers found that intravenous therapies made from virus-specific T-cells (VST) can effectively treat immunocompromised pediatric patients, far surpassing the current standard of care, according to new research published in Nature Communications.

More than 60% of patients in the phase 2 clinical trial led by investigators from Children’s National Hospital and Huntsman Cancer Institute responded to the innovative VST therapy. This new treatment uses blood from healthy donors to manufacture a highly specialized immune therapy that, when given to immune-compromised patients, prompts their immune system to fight off potentially life-threatening viruses, including cytomegalovirus, Epstein-Barr and adenovirus. Without this therapy, estimates suggest that less than 30% of patients would recover, using standard protocols.

“A vast majority of our patients not only responded to the therapy, but they were able to come off their antivirals, which come with extensive side effects,” said Michael Keller, M.D., the paper’s first author and the Translational Research Laboratory director at the Children’s National Cell Enhancement and Technologies for Immunotherapy (CETI) program. “This promising data suggests hope for patients with rare immune-compromising diseases that leave them vulnerable to so much in the world.”

The study brings together experts from the Pediatric Transplantation and Cell Therapy Consortium (PTCTC) and the Primary Immune Deficiency Treatment Consortium (PIDTC) to create the first multi-center, pediatric-consortium trial of adoptive T-cell therapies for viruses. It also represents one of the first to include critically ill patients, who are often excluded from research.

Children’s National leads the way

Working alongside Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research (CCIR), Dr. Keller and the CCIR team helped build an internationally recognized program, pioneering therapies to prevent complications from viral infections in immunocompromised patients. This includes patients with congenital immune deficiency and others who have undergone bone marrow transplantation for malignancies or non-malignant conditions, such as sickle cell disease.

While doctors can treat some immune-compromised patients for infections with standard antivirals, a small fraction don’t respond. Children’s National is one of a handful of hospitals in the country that has options. Over the last several decades, researchers have found ways to develop VST therapies made from banked T-cells, a more advanced application of how donated red blood cells are used to treat anemia.

In 2017, Drs. Keller and Bollard started collaborating with Michael Pulsipher, M.D.—now with Intermountain Primary Children’s Hospital and the Huntsman Cancer Institute at the University of Utah—to create a multi-institute clinical study. They combined the expertise at Children’s National in producing and banking cell therapy products with the community built around the PTCTC. Ultimately, they launched a clinical trial that was open to 35 centers in the U.S., enrolling 51 patients at 22 hospitals from 2018-2022.

“We wanted to prove that this potentially life-saving therapy could be given safely at regional pediatric centers that had never been able to use this approach before,” said Dr. Pulsipher, who served as the study’s co-principal investigator with Dr. Keller. “We united top experts in this area from the PTCTC and PIDTC and successfully treated some of the most challenging patients ever treated with this approach. Our findings helped define who can benefit the most from this therapy, paving the way for commercial development.”

The Good Manufacturing Practices (GMP) laboratory at Children’s National, led by Patrick Hanley, Ph.D., provided suitable VST therapies for 75 of 77 patients who requested to join the study. Clinical responses were achieved in 62% of patients who underwent stem cell transplants and in 73% of patients who were treated with VST and evaluated one month after their infusion. The paper laid out risks and clinical factors impacting outcomes when third-party donors are used to manufacture the VST therapies.

What’s ahead

Given that researchers are only beginning to develop cell therapies, work remains to understand the many ways they interact with the immune system. In a separate paper also recently published in Nature Communications, members of the multi-institute team documented a case of an infant with severe combined immune deficiency, who faced extremely rare side effects when the VST treatment interfered with her donor bone marrow graft. The case led the team to work with the Food and Drug Administration to identify criteria for VST donors enrolled in this study to mitigate complications.

In the decade ahead, Dr. Bollard sees promise in cell therapies for patients with cancer, immune deficiencies after transplant and dozens of other disorders, including genetic and autoimmune diseases. “Future studies will continue to look at ways to optimize the manufacturing, the administration and the long-term outcomes for these therapies—and to enhance the lifelong impact on our patients,” she said. “When we pair human ingenuity with the power of technology, I see tremendous potential.”

The international NexTGen team assembled at the Children’s National Research & Innovation Campus for their annual meeting to share progress made in their first full year of work on the $25-million Cancer Grand Challenge, focused on creating a CAR T-cell therapy for pediatric solid tumors.

“It was invigorating to bring the whole team together from our eight institutions in the U.S., U.K. and France, as we uncover opportunities in our research and share the headway that we have made,” said Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research and interim chief academic officer at Children’s National Hospital. “Breakthroughs happen when Team Science collaborates, and that is exactly what is happening here with the NexTGen team.”

Why we’re excited

Over the course of two days, more than 85 team members met to discuss the six work packages that are coming together, with the ambitious goal of making CAR T-cell therapies the standard of care for solid tumors within the next decade:

  • Discovery of new targets
  • The tumor microenvironment
  • Component engineering
  • Integration and modeling
  • Clinical studies
  • Data integration

Each work package includes a patient advocate – individuals with a personal connection to cancer as a family member or survivor – who offers their invaluable perspectives on the research and treatment process. Many attended the meeting, sitting alongside the oncologists, immunologists, mathematicians, molecular biologists and other leading experts.

The big picture

The Cancer Grand Challenges are funded by grants from the National Cancer Institute, Cancer Research U.K. and the Mark Foundation for Cancer Research. Their goal is to drive progress against cancer by empowering global leaders in the research community to take on tough challenges and think differently.

“They call it a ‘grand challenge’ for a reason,” Dr. Bollard said. “It’s going to take the effort and expertise of all these individuals to make a new therapy a reality. I have confidence that we can do it.”

Auditorium at the Cell and Gene Therapy in the DMV Symposium

Cell & Gene Therapy in the DMV: Experts collaborate for cures

Leaders in medicine, academia, industry and state and local government came together for the first annual Cell and Gene Therapy in the DMV Symposium, hosted at the Children’s National Research & Innovation Campus. The mission: Connect the local scientific community – bursting with expertise and collaboration potential – to develop these cutting-edge therapies for cancers, sickle cell disease and immune-mediated disorders.

The daylong event drew over 100 experts from a range of organizations in the D.C, Maryland and Virginia region, sometimes called the DMV: Children’s National Hospital, the Food and Drug Administration, the National Institute of Standards and Technology, the National Institutes of Health, the General Accounting Office, Virginia Tech, MaxCyte, AstraZeneca, Kite Pharma, Montgomery College, the Maryland State Department of Commerce and more. Together, they unraveled a host of topics including the regulatory environment, workforce development and training, research standards and the promise of these therapies.

“Our Cell & Gene Therapy Symposium brings together our current collaborators and future partners in the D.C., Maryland and Virginia space, which is an incredibly rich area. We see tremendous opportunity and breakthroughs in our future,” said Catherine Bollard, M.D., M.B.Ch.B., interim chief academic officer and chief of Pediatrics at Children’s National Hospital. “Many different diseases rely on the immune system to either be ramped up or to be controlled, and we can seize on these biological processes. Cell and gene therapies are at the heart of where medicine is going.”

The big picture

For decades, oncologists largely have turned to the same menu of treatments to fight cancer, including surgery, chemotherapy and radiation. Cell and gene therapies offer the promise of training the immune system to fight diseases with fewer side effects and potentially higher success rates. Early work has shown progress in liquid cancers, like leukemia, raising the possibility that the therapies could be used on solid tumors and other disorders, such as lupus and sickle cell disease. However, many disciplines must come together to yield discoveries.

“Nobel Prize-winning work doesn’t necessarily translate into available therapies for patients. It takes a whole community like this to make it happen,” said Cenk Sumen, chief scientific officer at MaxCyte Inc., an international cell engineering company based in Rockville, Md. “It has been exciting to see this diverse group of stakeholders come together, which is probably unmatched anywhere on the planet.”

Why we’re excited

Symposium host Patrick Hanley, Ph.D., chief and director of the Cellular Therapy Program at Children’s National, said the goal was to cement the region as the No. 1 location for this highly technical research and development. He believes Children’s National can offer essential elements to this success, given its clinical and research expertise, workforce training opportunities and geographic proximity to the scientific leadership of the federal government. “What makes us unique is our proximity to all the players who can help create new treatment options for patients. We truly are the biomedical capital of the world,” he said.

Michael Friedlander, vice president for health sciences at Virginia Tech, notes that the earliest stages of invention will emanate from academic labs including those at Virginia Tech and Children’s National. “You have basic scientists who are doing fundamental research on properties and procedures that will lead to the new therapies of tomorrow,” he said. “We are putting in place the fundamental pieces to advance children’s health in all dimensions.”

What’s ahead

One challenge is developing a workforce to help prepare cell therapies for patients, following precise standards to ensure the therapy works as designed. Children’s National does this training, as do others in the region. Lori Kelman, Ph.D., M.B.A., biotechnology coordinator and professor at Montgomery College, said that the area is full of people who want to help people and who like science.

“The thing that people might not know is that you don’t need a Ph.D. to work in cell and gene therapy,” she said. “There are opportunities at all levels, including the entry level, which is where a great career often starts.”

About the awards

Professorships at Children’s National support groundbreaking work on behalf of children and their families and foster new discoveries and innovations in pediatric medicine. These appointments carry prestige and honor that reflect the recipient’s achievements and donor’s forethought to advance and sustain knowledge. Children’s National is grateful for its generous donors, who have funded 47 professorships.

Dr. Keating is a longstanding leader in neurosurgery research and care. His areas of expertise include brain tumors, traumatic brain injuries, craniofacial anomalies, Chiari malformations and spinal dysraphism. With Dr. Keating’s leadership, the neurosurgery department is pioneering innovations such as HIFU, a non-invasive therapy using focused ultrasound waves to ablate a focal area of tissue. It can treat tumors located in difficult locations of the brain, movement disorders and epilepsy. Children’s National was one of the first pediatric hospitals in the nation to use HIFU for neuro-oncology patients.

“Our goal is to elevate our top-ranked program to even greater heights,” says Dr. Keating. “We will continue to use cutting-edge technology and non-invasive approaches to make the knife obsolete in pediatric neurosurgery and improve outcomes for children.”

Dr. Rood studies the biology of pediatric brain tumors. He focuses on protein signatures and biomarkers specific to different types of brain cancers. His study of neoantigens is informing the development of T-cell immunotherapies to target a tumor’s unique proteins.

“Immunotherapy is revolutionizing how we treat childhood brain tumors — safely, effectively and with the precision made possible by using a patient’s own cells,” says Dr. Rood. “This professorship enables our team to advance this revolution, which will save lives and improve lifetimes.”

Dr. Bollard received the Dr. Robert J. and Florence T. Bosworth Professor of Cancer and Transplantation Biology Research in 2018 to support her work to develop cell and gene therapies for patients with cancer and underlying immune deficiencies. Her professorship has been elevated to a distinguished professorship to amplify her research and celebrate her accomplishments in the field of immunotherapy.

A destination for pediatric oncology care: Children’s National Hospital’s T-cell therapy trials

When children are diagnosed with pediatric cancer, most doctors are forced to reach for the same standard therapies that were available decades ago. Research oncologists at Children’s National Hospital are changing that with clinical trials that will hopefully train the body’s immune system – specifically its T cells – to fight the tumors.

Holly Meany, M.D., and her colleague Amy Hont, M.D., oncologists and research scientists at the Center for Cancer and Immunology Research, have put together a pair of clinical trials that are investigating two pathways for using T cells to go after solid tumors.

“At Children’s National, we have a novel immunotherapy to offer to patients with relapsed or refractory solid tumors,” said Meany, director of the Solid Tumor Program. “This is a patient population who has failed standard therapy, so new technologies and treatments are always needed in this group.”

Where we started

Meany’s trial laid the foundation. She began the center’s research using a patient’s own blood sample to develop a targeted therapy and evaluate the safety and efficacy of this approach. In her study, scientists isolated the T cells, grew millions in a lab and reinfused them into the patient. The cells were replicated in an environment that was rich in three proteins that are commonly found on the surface of solid tumor cancer cells.

“Our hope and hypothesis are that when we give the T cells back to the patient, those T cells circulate and hunt down the cancer cells that have the tumor proteins,” Meany said. “We are hoping to use the patient’s own immune system to attack the cancer in an enduring way.”

Where we are headed

Hont’s phase 1 trial, which is currently recruiting participants, builds on Meany’s work using a healthy donor whose T cells have not been impacted by chemotherapy or other treatments. The cells can be prepared, stored and readily available for patients who need them. They are also matched through specific proteins on the patient’s own cells to bolster their effectiveness. The participants in this trial have Wilms tumors, rhabdomyosarcoma, neurosarcoma, soft tissue sarcoma or neuroblastoma, but conventional therapies including chemotherapy, radiation or surgery were unable to fully treat the disease.

In both studies, Hont said that the T cells have been given in an outpatient setting with fewer side effects compared to other cancer treatments aimed at high-risk malignancies.

“This allows patients to really maintain a good quality of life during a particularly hard time,” Hont said. “Also, these T cells are designed to act in the body the way that our immune system acts in a physiologic way. This means patients typically don’t have the severe side effects that we think of with chemotherapy or other therapies.”

Children’s National leads the way

The team at Children’s National is one of the few in the country to offer this kind of T-cell therapy for solid tumors. “Immunotherapy has been challenging for this patient population because the tumors are adept at finding out ways to evade treatment,” Hont said. “Giving patients a chance to receive a targeted T-cell therapy, while also maintaining a high quality of life, is something that’s special here.”

Cell therapy research for neuroprotection in congenital heart disease receives another $3.3 million from NIH

x-ray of child with congenital heart disease

Significant neurological delay is emerging as one of the most important current challenges for children with congenital heart disease, yet few treatment options are currently available.

The research lab of Nobuyuki Ishibashi, M.D., at Children’s National Hospital, recently received $3.3 million in additional funding for research into cell therapy for neuroprotection in children with congenital heart disease. The new support comes from the National Heart, Lung and Blood Institute (NHLBI) of the National Institutes of Health.

The research goal

The overarching goal of the award is to establish detailed molecular signatures from critical cell populations for tissue repair and regeneration at single cell resolution after bone marrow-derived mesenchymal stromal cell (BM-MSC) delivery. The team has shown cellular, structural and behavioral improvements in pre-clinical models after delivery of BM-MSCs through cardiopulmonary bypass for children with congenital heart disease. However, the mechanisms underlying the therapeutic action of BM-MSCs still remain largely unknown. This R01 renewal will address the key knowledge gap.

Why it matters

Significant neurological delay is emerging as one of the most important current challenges for children with congenital heart disease, yet few treatment options are currently available.

The Ishibashi lab has demonstrated the efficacy and utility of using cardiopulmonary bypass to deliver BM-MSCs  to improve neurological impairments in children undergoing surgery for congenital heart disease. Most notably, this included development of a phase 1 clinical trial, MeDCaP, at Children’s National.

The big picture

Together with the ongoing clinical trial established from the previous award, identifying molecular signatures of BM-MSC treatment and mining specific BM-MSC exosomes for unique cardiopulmonary bypass pathology will significantly improve understanding of this cell-based treatment. This work will also provide a new therapeutic paradigm for potential cell-free MSC-based therapies for neuroprotection in children with congenital heart disease.

$96 million philanthropic investment will transform rare pediatric brain tumor research and care

child in hospital bedChildren’s National Hospital announced a $96 million investment from an anonymous donor family to transform rare childhood brain tumor research and care. The donation, which strengthens our globally recognized leadership in the field, is one of the largest in the hospital’s history.

Children’s National will harness the investment to recruit more top talent and advance the most promising research. This will produce safer, more effective treatments. It also will elevate standards of care to help children with rare brain tumors thrive for a lifetime.

The big picture

Brain tumors are the most common solid tumors affecting children. They are especially challenging in kids because their brains are still developing. The disease and current treatments can put them at risk for lifelong complications.

The anonymous family’s investment provides new hope for patients who face rare and often challenging brain tumor diagnoses — in the Washington, D.C., community and around the world.

“This incredible partnership will lift up one of the nation’s top pediatric brain tumor programs into the stratosphere,” said Kurt Newman, M.D., president and CEO of Children’s National. “It will immediately propel our best-in-class research and care, allowing us to bring new therapies to children with brain tumors. This fundamentally changes the healthcare journey and long-term outcomes for children and their families.”

Why it’s important

This transformational investment will have a far-reaching impact on our ability to save and improve the lives of children with brain tumors. Funds will fuel collaborative breakthroughs across a range of scientific and psychosocial approaches.

The partnership will supercharge highly individualized and promising treatments for children with brain tumors. We will radically transform the research landscape with a focus on:

Children’s National Hospital ranked #5 in the nation on U.S. News & World Report’s Best Children’s Hospitals Honor Roll

U.S. News BadgesChildren’s National Hospital in Washington, D.C., was ranked #5 in the nation on the U.S. News & World Report 2023-24 Best Children’s Hospitals annual rankings. This marks the seventh straight year Children’s National has made the Honor Roll list. The Honor Roll is a distinction awarded to only 10 children’s hospitals nationwide.

For the thirteenth straight year, Children’s National also ranked in all 10 specialty services, with eight specialties ranked in the top 10 nationally. In addition, the hospital was ranked best in the Mid-Atlantic for neonatology, cancer, neurology and neurosurgery.

“Even from a team that is now a fixture on the list of the very best children’s hospitals in the nation, these results are phenomenal,” said Kurt Newman, M.D., president and chief executive officer of Children’s National. “It takes a ton of dedication and sacrifice to provide the best care anywhere and I could not be prouder of the team. Their commitment to excellence is in their DNA and will continue long after I retire as CEO later this month.”

“Congratulations to the entire Children’s National team on these truly incredible results. They leave me further humbled by the opportunity to lead this exceptional organization and contribute to its continued success,” said Michelle Riley-Brown, MHA, FACHE, who becomes the new president and CEO of Children’s National on July 1. “I am deeply committed to fostering a culture of collaboration, empowering our talented teams and charting a bold path forward to provide best in class pediatric care. Our focus will always remain on the kids.”

“I am incredibly proud of Kurt and the entire team. These rankings help families know that when they come to Children’s National, they’re receiving the best care available in the country,” said Horacio Rozanski, chair of the board of directors of Children’s National. “I’m confident that the organization’s next leader, Michelle Riley-Brown, will continue to ensure Children’s National is always a destination for excellent care.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals and recognizes the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News.

“For 17 years, U.S. News has provided information to help parents of sick children and their doctors find the best children’s hospital to treat their illness or condition,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “Children’s hospitals that are on the Honor Roll transcend in providing exceptional specialized care.”

The bulk of the score for each specialty service is based on quality and outcomes data. The process includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with the most complex conditions.

The eight Children’s National specialty services that U.S. News ranked in the top 10 nationally are:

The other two specialties ranked among the top 50 were cardiology and heart surgery, and urology.

Searching for the key to treating neuroblastoma tumors in kids

Cancer cells

Jianhua Yang, Ph.D., has dedicated his research to finding the molecular mechanism of neuroblastoma development and is working to develop novel therapeutics.

There continues to be an urgent need to identify novel therapies for childhood cancers. Neuroblastoma (NB) is the most common malignant solid tumor in children and contributes to more than 15% of all pediatric cancer-related deaths. Despite strides made in chemotherapy treatment over the past 30 years, NB largely remains an incurable disease. That’s why Jianhua Yang, Ph.D., associate professor and research faculty at the Center for Cancer and Immunology Research at Children’s National Hospital, has dedicated his research to finding the molecular mechanism of NB development and is working to develop novel therapeutics to target molecules he and his team identify in the lab.

Q: What has driven you to do this research?

A: In order to design better and potentially more effective NB treatment approaches, we must further understand the mechanism that activates NB development. We don’t know what that mechanism is yet, and that’s what we’re working to unlock. I felt with my training in cell biology and immunology, I could use that background to help develop novel therapies.

The research is hard and can often times feel frustrating. But I feel I’m working on something that has the potential to make a huge difference. I tell the researchers I work with that you have to really believe in what we’re doing. We’re doing something very different. Before I moved to D.C. to join Children’s National, I sent a text to a former mentor to let him know I was joining the team here to continue my work. His reply said, “I’ve always had confidence in you,” and it’s that type of encouragement that drives me to keep going.

Q: What is your current focus in this area?

A: Specifically, we’re working on two targets right now:

  1. To define the role and regulation of CaM kinase-like vesicle-associated (CAMKV) in NB development and examining the therapeutic potential of CAMKV kinase inhibition for treating NB in pre-clinical models. We’ve found that CAMKV is highly expressed in NB tumor samples and its kinase activity is required for tumor growth. So, if we knock out this gene, tumor cells will die. We’re studying how it is being activated, and if we can find out what causes it, we can find a way to inhibit its activation. Targeting CAMKV is a novel concept for treating NB. CAMKV kinase inhibitors may serve not only as stand-alone therapies but also as effective adjuncts to current chemotherapeutic regimens treating this aggressive pediatric malignancy.
  2. To define the role and regulation of transmembrane protein 108 (TMEM108) in NB development and examine the therapeutic potential of TMEM108 functional blockade for treating NB in pre-clinical models. Evolutionarily, in human genome it has no other family member, it’s a loner. And if you knock it out in NB tumor cells, tumor cells will die. We’re learning how it functions through our basic research, which is quite difficult. But we’re thinking if we can find the antibody to bind to it and block its function, we could stop the tumor from growing or even cause the tumor to die.

Q: What excites you about doing this work within the Center for Cancer and Immunology Research?

A: At Children’s National, I’ll be able to combine my work with the incredible work in immunotherapy that Drs. Catherine Bollard and Muller Fabbri are doing. I’m excited to be here to have that strong collaboration with their labs to develop new therapies.

In the next 5 years, I feel we’ll be able to identify good blocking antibodies that we can then test combinations of to see how it blocks tumor growth. If we can find ways to combine that antibody therapy with traditional chemotherapy options, we can achieve a real cure for NB.

Research into a new way to combat solid tumors earns part of a $25M award

Drs. Bollard and Hanley

Catherine Bollard, M.D., M.B.Ch.B., and Patrick Hanley, Ph.D.

Children’s National Hospital has developed multi-antigen specific T cells that have shown success in pre-clinical models in attacking pediatric solid tumors. Now the promising area of research earned a major boost from the Cancer Grand Challenges — founded in 2020 by the two largest funders of cancer research in the world – Cancer Research UK and the National Cancer Institute in the U.S.

This award supported the foundation of NexTGen, a team of scientists and clinicians with expertise in immunology, proteomics, mathematics and more, across eight institutions in the U.S., U.K. and France. Catherine Bollard, M.B.Ch.B, M.D., director of the Center for Cancer and Immunology Research at Children’s National, and Martin Pule, M.D., clinical associate professor at the University College of London are the co-leads of this effort.

The NexTGen team is one of four Cancer Grand Challenges’ new teams, representing a total investment of $100M to diverse, global teams to take on some of the toughest challenges in cancer research. NexTGen will create a new approach that performs clinical and basic research together to facilitate real-time knowledge exchange from the lab to the clinic and back again.

While the more widely known CAR T-cells have made tremendous progress for patients with B-cell leukemias, lymphomas and other blood cancers, the CAR T-cell field has not made the same impact for adult and pediatric solid tumors.

“A tumor cell is very clever because it tries to hide from the immune system by deleting or down regulating targets that the T cell is directed towards,” said Dr. Bollard.

Dr. Bollard further discusses the importance of having patient voices during the decision-making process in this quest, her hopes for their program and the concept of the combining tumor antigen-specific T cells with CAR-T cells that her team will develop.

Q: Can you explain the NexTGen vision?

A: The overall vision is that we will have developed the next generation of cell therapies to cure children with refractory solid tumors by the end of the five years. It is important to move the field forward, so we wanted to be innovative in our approach to this grand challenge for these children who have no other therapeutic options left.

Q: What are the most three important components of this project?

A: First, science and diplomacy played a significant role in bringing in the right set of investigators from diverse scientific backgrounds. What started as a conversation using the universal language of science, it quickly became an international project to address this complex issue. Second, we worked very hard with our patient advocates during the writing process, and they will be working side by side with the investigators at the bench and clinic. Third, we were the only group to have clinical trials in our proposal starting very early in the grant funding period, which is unprecedented.

Q: Can you describe NexTGen’s research model?

A: From our experience in leukemia, we know that progress is greatly accelerated if discovery occurs hand-in-hand with clinical development. Therefore, unlike classical programs where years of pre-clinical discovery and developmental work is required before the clinical translation, we will take a non-conventional non sequential approach.

Specifically, in the NexTGen Program, clinical development will start early with three cutting-edge clinical studies evaluating engineered T-cell technologies that we have recently developed understanding that there are some questions that can ONLY be answered in the clinic. To that end, clinical and translational data from these clinical trials will be able to feed into and enrich the discovery and pre-clinical science throughout the NexTGen Program in a circular fashion to promote this research program that goes from bedside to bench and back.

Q: How is Children’s National leading the way?

A: Children’s National is leading one of the three clinical trials that combine our non-gene engineered tumor antigen-specific T-cell platform with gene engineered T cells to generate a novel T-cell therapy against relapsed /refractory solid tumors. Combining tumor antigen specific T cells with the CAR T-cell platform represents a novel concept that may have more potency against these hardest to treat tumors in children.

Q: Why is it so important to include the patient voice during the discussion and decision making?

A: Because we are also physicians and scientists, we do not forget the patient and their families. Thus, we have a robust patient advocacy group embedded in this vision. The group will co-develop summaries explaining the challenges NextGen will address, how this will be achieved and how results will be used, with major input in clinical trial design and consent documents as well as key input into how patient tissue samples can be used to facilitate research discoveries. The patient advocacy team will also help find broad representation from multiple geographical locations of advocates with lived experience of different cancer types, including bereaved relatives and cancer survivors. These and many more strategies applied with patient advocacy groups will elevate the call for a broader and accelerated adoption of CAR-T clinical trials to broaden access to all patients.

Q: What excites you most about this?

A: What excites me the most is working with this incredible group of scientists, physicians and patient advocates all with rich and deep expertise who bring together an extensive and diverse knowledge base. The fact that we will be all working together toward a common goal of curing pediatric solid tumors in the next five to 10 years is extraordinarily energizing. This sizeable international collaboration comprises the right talent to get this done. It is also highly exciting to simultaneously have three clinical trials running in parallel with the discovery science and the pre-clinical work. I am extremely optimistic that we will realize NexTGen’s vision to bring next generation engineered T-cell therapies to the routine care of children with solid tumors within a decade.

A world-class team of researchers co-led by Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research at Children’s National Hospital, has been selected to receive a $25m Cancer Grand Challenges award to tackle solid tumors in children. Cancer Grand Challenges is a global funding platform, co-founded by Cancer Research UK and the National Cancer Institute in the U.S., that supports a community of diverse, global teams to come together, think differently and take on some of cancer’s toughest challenges.

The Cancer Grand Challenges NexTGen team, co-led by University College London’s Martin Pule, M.D., will be working to develop next-generation cell therapies for children with solid cancers. Cancer is a leading cause of death by disease in children worldwide. Although survival has increased for some pediatric cancers, such as blood cancers, survival for some solid tumors has seen little improvement for more than 30 years. The team hopes to build a much deeper understanding of childhood cancers and develop and optimize novel therapies for children with solid tumors, ultimately hoping to improve survival and diminish the lifelong toxicities often experienced by survivors.

“With our Cancer Grand Challenge, we hope to bring next-generation CAR T-cell therapies to children with solid tumors,” said Dr. Bollard. “What excites me most is the energized, passionate group of people we’ve brought together to take this challenge on. Big problems remain to be addressed, but we believe they can be solved, and that we’re the team to solve them.”

“NexTGen represents crucial and overdue work. It has hope written all over,” said Sara Wakeling, patient advocate on the team and CEO and co-founder of Alice’s Arc, a children’s charity for rhabdomyosarcoma. “NexTGen hopes to transform the way these aggressive solid tumors are treated with less toxic side-effects, giving the children a real chance at growing up and realizing their potential. I’m so proud to be part of this exceptional team of scientists, clinicians and advocates who want to change the story for those diagnosed.”

The NexTGen team unites scientists and clinicians with expertise in immunology, proteomics, mathematics and more, across eight institutions throughout the U.S., U.K. and France. The Children’s National investigators that will also join are:

  • Nitin Agrawal, Ph.D., associate professor in the Center for Cancer and Immunology Research at Children’s National.
  • Conrad Russell Cruz, M.D., Ph.D.,principal investigator for the Program for Cell Enhancement and Technologies for Immunotherapies at Children’s National.
  • Patrick Hanley, Ph.D., chief and director of the cellular therapy program at Children’s National and leader of the Good Manufacturing Practices laboratory.
  • Amy Hont, M.D., oncologist in the Center for Cancer and Immunology Research at Children’s National.
  • AeRang Kim, M.D., oncologist in The Center for Cancer and Blood Disorders at Children’s National.
  • Holly Meany, M.D., oncologist in The Center for Cancer and Blood Disorders at Children’s National.
  • Anqing Zhang, biostatistician in the Biostatistics and Study Methodology Department at Children’s National.

The team, co-funded by Cancer Research UK, the National Cancer Institute and The Mark Foundation for Cancer Research, aims to bring much needed new treatments to children with solid cancers.

The NexTGen team is one of four new teams announced today as part of Cancer Grand Challenges, representing a total investment of $100m to diverse, global teams to take on some of the toughest challenges in cancer research.

“Cancer is a global issue that needs to be met with global collaboration. This investment in team science encourages diverse thinking to problems that have long hindered research progress,” said David Scott, Ph.D., director of Cancer Grand Challenges, Cancer Research UK. “Cancer Grand Challenges provides the multidisciplinary teams the time, space and funding to foster innovation and a transformative approach. NexTGen is one of four newly funded teams joining a scientific community addressing unmet clinical needs across cancer research.”

Developing next-generation T cells to fight cancer

In the last decade, researchers have witnessed significant advances in the immunotherapy field. Most recently, a study in Nature claimed a novel CAR T-cell therapy “cured” a patient.

In the last decade, researchers have witnessed significant advances in the immunotherapy field. Most recently, a study in Nature claimed a novel CAR T-cell therapy “cured” a patient. Given the landmark scientific achievement for patients with different types of leukemia and lymphoma, Children’s National Hospital experts chimed in on the technology they have developed beyond CAR T cells.

Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research at Children’s National Hospital, discusses the implications of this research, how it relates to the work she’s doing at Children’s National and the future of T-cell therapies.

Q: What did the research published in Nature find?

A: It reported a decade-long experience with this novel T-cell therapy called CD19 CAR T cells. These were used to treat patients with a type of leukemia or lymphoma that expresses the CD19 on its surface. While the article reported the experience of Children’s Hospital of Philadelphia and the University of Pennsylvania, multiple groups throughout the country did similar trials that have used these unique CD19 CAR T cells to treat children and adults with these refractory blood cancers.

Q: What are your thoughts on the implications of this research?

A: We now have three FDA-approved commercial CD19 CAR T-cell products developed by several academic institutions. This is revolutionary for our patients who have B-cell leukemias and lymphomas. It’s incredibly exciting for our T-cell therapy field in general because this was the first time the FDA approved a T-cell therapy. What it means now is the field is extremely excited to develop similar effective therapies for other patients with cancer.

Q: How does this relate to your work at Children’s National?

A: While CAR T cells have made tremendous progress for patients with B-cell leukemias, lymphomas and other blood cancers, the CAR T-cell field has not made the same impact for adult and pediatric solid tumors. We think the field is going to expand the type of T-cell therapies we’re generating beyond just CAR T cells. That’s where the work we’re doing comes in – not only by developing new T cells that don’t need gene engineering but also T cells that can be used as a platform for next-generation engineering approaches. We think the technology we’ve developed at Children’s National will help make an impact, especially in the solid tumor space. I hope in the next 10 years, we’ll be having a conversation not just about CAR T cells, but about other types of T cells that are now making an impact for solid tumors.

Q: How are the CAR T cells you develop different than those in the Nature article?

A: We think our multi-antigen specific T cells are complimentary and could have more potency than conventional CAR T cells for solid tumors especially when used in combination. This is in part because they can identify multiple targets on a tumor cell. Tumor cells are very clever and try to hide from T-cell therapies by down regulating the target that the T cell is directed towards. However, our novel T-cell therapies get around that escape by targeting multiple targets in a single product, making it much harder for the cancer cell to hide from the immune attack by the T cells.

Additionally, we’re excited by our approach because not all of our products require gene engineering, unlike CAR T cells. We have effectively used our T cells to target viruses in the “off-the-shelf” setting and we’re now about to start a first human clinical trial at Children’s National using an off the shelf T-cell product for children with solid tumors. It makes the T-cell therapy more like an “off-the-shelf” drug therapy that will allow us to treat many more children and adults nationally, as well as we hope, internationally.

Manufactured leukemia-specific T cells may help increase survival rates

doctor and cancer patient smiling

Infusion of a novel, multi-targeted donor-derived T-cell therapy is safe and well-tolerated in patients with high-risk or relapsed leukemia after a donated bone marrow transplant, according to a new study published in Blood Advances.

Infusion of a novel, multi-targeted donor-derived T-cell therapy is safe and well-tolerated in patients with high-risk or relapsed leukemia after a donated bone marrow transplant, according to a new study published in Blood Advances. The findings suggest that this strategy may make a difference in these patients, as will be evaluated in later phase trials.

“A tumor cell is very clever because it tries to hide from T-cell therapies by deleting or down regulating targets that the T cell is directed towards,” said Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research at Children’s National Hospital and co-senior author. “This novel cell therapy has the potential to get around that escape by targeting multiple proteins in a single product, making it much harder for the cancer cell to hide from the immune attack by the T cells.”

The tumor-associated antigen-specific T cell (TAA-T) product targets WT1, survivin and PRAME, which are proteins that play a role in cancer cell proliferation and survival. They are overexpressed in leukemia and many other human malignancies. The researchers chose to expand the T cells to target many malignancies through at least one expressed antigen. The manufactured TAA-T products are derived from peripheral blood mononuclear cells (PBMCs) obtained from the patient’s own BMT donor.

The hold-up in the field

Conventional therapies for patients with high-risk or relapsed malignancies often fail due to toxicity associated with additional chemotherapy and second transplant, particularly in those who relapse early after transplant. This novel cellular immunotherapy approach is shown to be safe and targets antigens that are found in CD19 positive and negative blood cancers, which may broaden the applicability to other cancer types, such as acute myeloid leukemia, that are currently lacking effective T cell therapy options.

What’s next

“Evaluation and tracking of unique T cell receptor clonotypes in patients following TAA-T cell infusion demonstrated expansion and persistence of some clonotypes up to 6 months to one-year post-infusion,” said Hannah Kinoshita, M.D., oncology fellow at Children’s National and co-lead author. “In future studies, we are hoping to identify and track unique target antigen-specific clonotypes from the T cell product infused to better understand the immunobiological effect of the infused T cells and how that can be translated into improved clinical outcomes.”

Children’s National Hospital leads the way

The Cell Enhancement and Technologies for Immunotherapy (CETI) program at Children’s National specializes in developing and analyzing novel cellular therapeutics such as this one.

You can read the full study “Outcome of Donor-derived TAA-T cell therapy in Patients with High-risk or Relapsed Acute Leukemia Post Allogeneic BMT,” in Blood Advances. Children’s National researchers worked in partnership with Rick Jones, M.D., co-senior author and Kenneth Cooke, M.D., Ph.D., co-lead author, both at Johns Hopkins Medicine.

Advancing immunotherapy for pediatric brain tumors

cancer cells

While immunotherapy has revolutionized cancer treatments, its efficacy remains relatively undefined in pediatric settings for brain tumors.

While immunotherapy has revolutionized cancer treatments, its efficacy remains relatively undefined in pediatric settings for brain tumors. Children’s National Hospital experts and other institutions argue in a review published in Nature Cancer that there is a need for closer collaborations between academia, industry partners, regulatory bodies and funders to progress the field.

Eugene Hwang, M.D., associate division chief of Oncology and neuro-oncologist at Children’s National, led the review that outlines immunotherapeutic hurdles and simultaneously proposes next steps for immunotherapy use in these patients. These considerations will aid pediatric oncologists make better recommendations and advances in this type of treatment.

“The promise of immunotherapy in helping to cure children with brain tumors is exciting,” Dr. Hwang said. “This type of approach has already revolutionized treatments for many different kinds of cancer, and a comprehensive review of this complicated arena, especially by leading voices in the field, can help set the stage for finally moving the needle for these patients.”

The review is especially helpful as children harbor unique elements of immunity and the brain presents distinct obstacles to immune attack that are not present in other cancers. For example, there are challenges in antigen identification, the blood-brain barrier and the tumor microenvironment. For many pediatric cancer doctors as well this novel, complex form of therapy is outside of their historical training.

To overcome these challenges, the authors encourage philanthropic organizations and patient advocacy groups to be part of the process that can help fill funding gaps in patient-focused pre-clinical and clinical research and educate patients and families.

“Multiple stakeholders around pediatric brain cancer immunotherapy must be mobilized in a concerted fashion,” Hawk et al. argue in the piece. “The need for close academic collaboration with industry partners and regulatory bodies is increasingly apparent given the unique pediatric phenotypes and complex outcomes in immunotherapeutic trials, and progress will be made at the interface of the interactions of all these key stakeholders.”

The group of internationally renowned pediatric brain tumor-focused immunotherapy experts comprehensively reviewed the advances in the major modalities of immunotherapy and the landscape of preclinical modeling for these patients to date.

Investigators at Children’s National, for example, are leading several national and international trials involving immunotherapy which have spurred international meetings with a focus in childhood brain tumor immunotherapies.

“The multiple T cell trials led by Children’s National are perfect examples of truly field-leading innovative immunotherapy, as are the other trials that are led by our own investigators,” Dr. Hwang added.

Keri Toner, M.D., and Hannah Kinoshita, M.D., both oncology researchers at Children’s National Hospital, were recently awarded Hyundai Hope on Wheels cancer research grants.

Dr. Toner, who is an attending physician in the Center for Cancer and Blood Disorders and the Center for Cancer and Immunology Research at Children’s National, received a $300,000 Hyundai Scholar Hope Grant that she will use to develop and functionally evaluate a novel T cell therapy which can be translated to the clinic for treatment of pediatric patients with acute myeloid leukemia (AML).

Currently, patients with relapsed AML have very poor outcomes and the success that T cell therapy has had in treating B-cell malignancies has not yet been achieved for AML. Dr. Toner’s goal is to try to overcome some of these barriers with a novel T cell therapy which combines both native and chimeric T cell receptors to target AML.

“There are currently critical barriers to the success of T cell therapies for the treatment of AML,” Dr. Toner explains. “Successful completion of this research would allow for translation of a novel CAR-TAA-T therapy to the clinic for the treatment of relapsed/refractory AML, which has very poor prognosis.”

Meanwhile, Dr. Kinoshita, a pediatric hematology oncology fellow at Children’s National, received a $200,000 Hyundai Young Investigator Grant. She will use the funds to evaluate the immunobiology of multi-antigen specific T cell therapy infused to patients to reduce the two most common causes of morbidity and mortality following hematopoietic stem cell transplant (HSCT) for malignant disease: relapse and infection.

The administration of multiantigen specific T cells targeting tumor and viral-associated antigens following stem cell transplant may serve to prolong remission of malignant disease and prevent and treat viral infections that can cause devastating disease in children. Dr. Kinoshita’s study will evaluate the anti-viral and anti-leukemia immune response in vivo following targeted T cell therapy.

“There have been incredible advancements in the field of pediatric oncology and bone marrow transplant over the past 20-30 years but there are still many areas in which we need to continue to improve,” Dr. Kinoshita says. “Our patients and their families go through so much to get into remission and it is devastating if they relapse or develop severe infectious complications. Adoptive immunotherapy is a promising tool in aiding to treat and prevent these complications, particularly for patients with high-risk hematologic malignancies.”

The Hyundai Scholar Hope Grants and the Hyundai Young Investigator Grants are competitive research grants that are peer-reviewed by the Hyundai Hope on Wheels Medical Advisory Committee, which is comprised of leading pediatric oncologists from children’s hospitals and research institutions nationwide. The grants are open to U.S.-based Children’s Oncology Group member institutions.
