Closing the ‘Valley of Death’: Pioneering – and paying for – new therapies

Catherine Bollard, M.D., M.B.Ch.B., director of the Children’s National Center for Cancer and Immunology Research

“To cure brain tumors, sickle cell disease and scores of other illnesses that have an outsized impact on pediatric patients, we will need an innovative mechanism to ensure that money is not a barrier to scientific advancement and world-class care,” says Dr. Bollard.

With the advent of life-changing cell and gene therapies (CGTs) to treat pediatric diseases, price is becoming a significant obstacle to care and cures.

Successful therapies can wind up shelved or in hard-to-reach clinical trials for a litany of reasons: high manufacturing costs, significant regulatory burdens, a lack of enthusiasm from the pharmaceutical industry in the small pediatric market and the simple fact that insurance companies resist paying the price of $1 million or more for a therapeutic. When successful treatments are set aside and become victims of this market failure, leaders in pediatric medicine say the drug has been relegated to the “Valley of Death.”

Experts at Children’s National Hospital and other leading U.S. research institutions are working to ferry drugs across it.

A new way forward

The Access4Kids think tank is bringing together healthcare leaders to chart another way – with its hosts Catherine Bollard, M.D., M.B.Ch.B., director of the Children’s National Center for Cancer and Immunology Research, Crystal Mackall, M.D., director of the Stanford Center for Cancer Cell Therapy, Julie Park, M.D., Oncology Department chair at St. Jude Children’s Research Hospital, and Alan Wayne, M.D., pediatrician-in-chief at Children’s Hospital Los Angeles. Organized at the Children’s National Research & Innovation Campus, the think tank will include voices from Seattle Children’s Hospital in Washington state and the Moonshot Presidential Office in Washington, D.C., along with experts from academic institutions, the federal government and patient advocacy groups.

They explained their vision in their recent Nature Medicine perspective,  “Enhancing pediatric access to cell and gene therapies.” One idea under consideration is to create a biotech enterprise – backed by public monies, foundations and philanthropies – to support the late-stage development and commercialization of pediatric CGTs. Called a Pediatric Advanced Medicines Biotech (PAMB), this new organization would follow a novel pathway outside the traditional biopharma development model.

“To cure brain tumors, sickle cell disease and scores of other illnesses that have an outsized impact on pediatric patients, we will need an innovative mechanism to ensure that money is not a barrier to scientific advancement and world-class care,” Dr. Bollard said. “My colleagues and I aren’t exaggerating when we say this is a ‘save the world’ effort. It’s an initiative to disrupt the pharmaceutical industry and impact medicine, ultimately saving lives and entire lifetimes.”

The think tank is the second in a series aimed at solving this formidable challenge. Led by scientists, the work goes to the heart of healthcare economics.

“We need to find a way to support the academic ecosystem by reducing costs, creating efficiencies in manufacturing and working with regulatory bodies to bolster business models that lead to safe and effective therapeutics,” Dr. Mackall said. “We went to school to study science and medicine. Now, our mission includes revamping business models, as we find ways to increase access to lifesaving treatments for children in need.”

Why it matters

Creating novel pathways to pay for CGTs presents a challenge and an opportunity for researchers in pediatrics and rare diseases. Drs. Mackall, Bollard and their colleagues are exasperated when scientists discover successful treatments for life-threatening illnesses, but market forces lock the drug away in hard-to-reach clinical trials or – even worse – land it on a shelf.

Consider just one example, laid out in the Nature Medicine perspective: Children with adenosine deaminase-deficient severe combined immunodeficiency (ADA-SCID) lack nearly all protection from viruses, bacteria and fungi, leaving them vulnerable to a world of opportunistic organisms. Researchers at San Raffaele Telethon Institute for Gene Therapy in Italy won U.S. and European regulatory approvals for a gene replacement therapy to treat the life-threatening disorder. Yet currently the therapy is only available in clinical trials, with support from research grants, philanthropic donations and institutional resources.

“This happens to successful therapeutics, and it’s heartbreaking. The current business model in medicine can lead to situations where successful therapies have extremely restricted availability, and there are no built-in guarantees of sustained access,” Dr. Bollard said. “We can and must do better – and we believe we have a way forward.”

Mission critical: Pentagon awards grant to combine two novel brain tumor therapies

graphic explaining LIFU and CAR TA Children’s National Hospital researcher is embarking on a two-year project that could revolutionize the care of rare pediatric brain tumors, through a Department of Defense (DOD) award to study the efficacy of combining the powers of acoustic therapy and cellular immunotherapy to treat the deadliest forms of medulloblastoma.

Designed by DOD to advance novel innovations that could revolutionize medicine, the prestigious Idea Award supports independent investigators with high-risk, but potentially high-reward, concepts to fill gaps in cancer prevention and treatment. Dalia Haydar, Pharm.D., Ph.D., principal investigator at the Cell Enhancement and Technologies for Immunotherapy Program, believes her first-of-its-kind approach could do just that.

A one-two punch

Dr. Haydar is building on promising research into a novel type of immunotherapy – chimeric antigen receptor (CAR) T-cell therapy – which uses the body’s own immune system to target and destroy pediatric brain tumors. She hopes to combine the potential of this immunotherapy with the early success seen in an acoustic therapy, called low-intensity focused ultrasound (LIFU). Akin to the imaging technology used during pregnancy, the sound waves can be directed toward any organ of the body for therapeutic reasons. With LIFU, Dr. Haydar hopes to tune the right amount of energy toward a brain tumor to temporarily open the blood-brain barrier and improve the delivery of therapeutics.

“We’re using two treatments that are tested in the clinic. We know how they work individually, but we’re investigating methods to combine the best aspects of both,” Dr. Haydar said. “I hope to use it, not just to open the channels in the blood-brain barrier, but also to cause a certain kind of immune response in the brain, which will help the CAR T-cells fight cancer.”

This collaborative grant includes experts in the field, including Yanxin Pei, Ph.D., principal investigator at Children’s National and an expert in medulloblastoma modeling, and Natasha Sheybani, Ph.D., assistant professor at the University of Virginia and a leading figure in the application of focused ultrasound.

Why we’re excited

Dr. Haydar is initially focused on high-risk medulloblastoma, specifically sonic hedgehog and group 3 subtypes, both of which are often fatal with existing chemotherapy and radiation treatments. Even when successful, the standard treatments can lead to life-long developmental side effects. Dr. Haydar hopes to show that the combined treatment improves survivorship, and she anticipates expanding her work to other types of pediatric brain tumors.

The $600,000 award shows the importance of well-resourced research institutions uniquely focused on pediatrics. Dr. Haydar noted that Children’s National is one of few research hospitals in the country with the necessary laboratory and ultrasound equipment on-site to develop a customizable treatment protocol. “We’re not just proposing to test this as a science project,” she said. “We’re proposing something that we can very well translate into the clinic and into a new approach for pediatric cancer patients.”

What we hope to discover

Through congressional funding, the Defense Department – one of the largest providers of pediatric healthcare for U.S. children – looks for opportunities to support the needs of military personnel and their dependents. Much of Dr. Haydar’s work will focus on determining safety and optimizing the delivery of the two treatments.

“You have to find the ideal timeline,” Dr. Haydar said. “Which therapy do you do first? How much spacing is best between them, and when do you repeat the therapy? What is the best dosing? It’s a puzzle, and I am hoping to solve it to give children with these often-fatal diagnoses a longer life – and a better one than existing treatments provide.”

Pioneering gene therapy as a treatment for sickle cell disease

Gene therapy is a new and exciting treatment option available for patients with sickle cell disease (SCD). Children’s National Hospital is one of the few pediatric hospitals in the country that offers both FDA-approved sickle cell disease gene therapies: CASGEVY™ (exagamglogene autotemcel) and LYFGENIA™ (lovotibeglogene autotemcel).

What this means

Gene therapy involves an autologous transplant, taking the patient’s own stem cells, genetically changing those stem cells and then, after chemotherapy, infusing those stem cells back into the patient to make healthy blood.

“I’m excited about gene therapy for sickle cell disease. I think it has the potential to be a curative option for every single child with sickle cell disease,” said Robert Nickel, M.D., hematologist at Children’s National.

Currently both treatments are only approved for patients 12 years and older with severe disease. Children’s National was the first hospital in the world to collect stem cells for the LYFGENIA™ treatment.

Moving the field forward

Clinical trials hold incredible promise to advance the care of SCD. Children’s National continues to pioneer transplant therapies to cure SCD and is one of the leading centers participating in clinical trials of new treatments for this condition.

Experts at Children’s National are leading a multi-site clinical trial of a chemotherapy-free transplant approach for SCD using a matched sibling donor. This chemotherapy-free approach has less toxicity and side effects for children undergoing transplant.

In addition, Children’s National has been leading the way with innovative approaches to support sickle cell patients. “We’re providing alternative approaches to pain such as healing touch, acupuncture, massage VR technology, physical therapy and exploring other ways of treating pain in an integrated manner,” said Andrew Campbell, M.D., director of the Comprehensive Sickle Cell Disease Program at Children’s National.

The team is also exploring non-opioid treatments, such as intravenous citrulline, a naturally occurring amino acid that has been proven to enhance blood flow and potentially alleviate pain in treated patients in preliminary studies under the direction of Suvankar Majumdar, M.D., chief of Hematology at Children’s National.

Artificial – and accelerated – intelligence: endless applications to expand health equity

In the complex world of pediatric diseases, researchers need access to data to develop clinical trials and the participation of vulnerable patients to develop new devices and therapies. Both are in short supply, given that most children are born healthy, and most severe pediatric diseases are rare.

That creates a dilemma: how do researchers build a foundation to advance new treatments? Enter artificial intelligence (AI).

“AI is the equalizer: accelerated intelligence for sick kids. No other advance on the horizon holds more promise for improving equity and access to pediatric healthcare when diseases are rare and resources are limited,” says Marius George Linguraru, D.Phil., M.A., M.Sc., the Connor Family Professor in Research and Innovation and principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI). “AI will shrink the distance between patient and provider, allowing our physicians and scientists to provide targeted healthcare for children more efficiently. The possibilities are endless.”

Why we’re excited

By pioneering AI innovation programs at Children’s National Hospital, Dr. Linguraru and the AI experts he leads are ensuring patients and families benefit from a coming wave of technological advances. The team is teaching AI to interpret complex data that could otherwise overwhelm clinicians. Their work will create systems to identify at-risk patients, forecast disease and treatment patterns, and support complex clinical decisions to optimize patient care and hospital resources. Already, the AI team at SZI has developed data-driven tools touching nearly every corner of the hospital:

  • AI for rheumatic heart disease (RHD): In partnership with Children’s National cardiology leaders, including Craig Sable, M.D., the Uganda Heart Institute and Cincinnati Children’s Hospital, the AI team has developed an algorithm that can use low-cost, portable ultrasound imaging to detect RHD in children and young adults, a disease that takes nearly 400,000 lives annually in limited-resource countries. Early testing shows the AI platform has the same accuracy as a cardiologist in detecting RHD, paving the way for earlier treatment with life-saving antibiotics. This year, Children’s National physicians will be in Uganda, screening 200,000 children with local cardiology experts and AI technology.
  • Newborn screening for genetic conditions with mGene: Working with Rare Disease Institute clinicians and Chief of Genetics and Metabolism Debra Regier, M.D., the AI team has built technology to detect rare genetic disorders, using an algorithm and a smartphone camera to identify subtle changes in facial features. Tested on patients from over 30 countries and published in The Lancet Digital Health, the application helps screen children for advanced care when a geneticist may not be within reach. With funding from the National Institutes of Health, Children’s National and its research partners are piloting a newborn screening program in the Democratic Republic of the Congo.
  • Pediatric brain tumors: To improve and personalize the treatment decisions for children with brain tumors, Dr. Linguraru’s team is working with Brain Tumor Institute Director Roger Packer, M.D., the Gilbert Family Distinguished Professor of Neurofibromatosis, on algorithms that can characterize and measure brain tumors with unprecedented precision. The team recently won the International Pediatric Brain Tumor Segmentation Challenge, distinguishing the Children’s National algorithm as among the best in the world.
  • Ultra-low field magnetic resonance imaging (MRI): With a grant from the Bill & Melinda Gates Foundation, the AI team is working alongside Children’s Hospital Los Angeles, King’s College London and the UNITY Consortium to expand global brain imaging capacity. The consortium is helping clinicians in limited-resource countries improve the treatment of neonatal neurological conditions, using AI to boost the quality of ultra-low field MRI and expand access to this portable and more affordable imaging option.
  • Federated learning: Children’s National has collaborated with NVIDIA and other industry leaders to accelerate AI advances through federated learning. Under this approach, institutions share AI models rather than data, allowing them to collaborate without exposing patient information or being constrained by essential data-sharing restrictions. The SZI team was the only pediatric partner invited to join the largest federated learning project of its kind, studying the lungs of COVID-19 patients. Details were published in Nature Medicine.

Children’s National leads the way

Looking ahead, the Children’s National AI team is pursuing a wide range of advances in clinical care. To support patients treated at multiple clinics, they are developing systems to harmonize images from different scanners and protocols, such as MRI machines made by different manufacturers. Similar work is underway to analyze pathology samples from different institutions consistently.

Automation is also making care more efficient. For example, using data from 1 million chest X-rays, the team is collaborating with NVIDIA to develop a conversational digital assistant that will allow physicians to think through 14 possible diagnoses.

Dr. Linguraru says he and his colleagues are galvanized by the jarring statistic that one in three children with a rare disease dies before age 5. While well-implemented AI initiatives can change outcomes, he says the work must be done thoughtfully.

“In the future, patients will be evaluated by human clinicians and machines with extraordinary powers to diagnose illness and determine treatments,” Dr. Linguraru said. “Our team at Children’s National is leading conversations about the future of pediatric healthcare with a focus on safety, resource allocation and basic equity.”

Learn more about our AI initiatives

Innovation leaders at Children’s National Hospital are building a community of AI caregivers through educational and community-building events. At the inaugural Symposium on Artificial Intelligence in 2023 at the Children’s National Research & Innovation Campus, experts from Virginia Tech, JLABS, Food and Drug Administration, Pfizer, Oracle Health, NVIDIA, AWS Health and elsewhere laid out a vision for using data to advance pediatric medicine. The symposium will return on Sept. 6.

Dr. Linguraru is the program chair of MICCAI 2024, the top international meeting on medical image computing and computer-assisted intervention and the preeminent forum for disseminating AI developments in healthcare. The conference is an educational platform for scientists and clinicians dedicated to AI in medical imaging, with a focus on global health equity. It will take place for the first time in Africa on Oct. 6-10.

Novel cell therapy treatments offer promise to immune-compromised children

teenager receiving an intravenous infusion

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.”

Acknowledgments: This study was funded with a nearly $5 million grant from the California Institute of Regenerative Medicine and was run through the operations center at the Children’s Hospital of Los Angeles, where Dr. Pulsipher was formerly on faculty.

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.”

Novel camera + machine learning = hope for more precise neurosurgery

collage of hyperspectral imaging (sHSI) camera and brain surgery

Researchers at Children’s National Hospital developed a compact imaging camera capable of seeing beyond the human visual spectrum to help segment healthy brain tissue from tumors during surgery. The groundbreaking technology will allow neurosurgeons to make more precise, real-time decisions in the operating room, rather than sending samples to pathology labs for biopsies.

In a manuscript published in Bioengineering, the team of engineers and neurosurgeons details how its snapshot hyperspectral imaging (sHSI) camera can be used to capture and process images of brain tissue, using the wide spectrum of light between visible and infrared wavelengths. That additional information — beyond the human eye — has the potential to allow for more accurate and complete tumor removal.

“In the hands of a neurosurgeon, this camera, when combined with machine learning, could dramatically improve outcomes for some of our most vulnerable brain tumor patients,” said Richard Jaepyeong Cha, Ph.D., an optical engineer and principal investigator at the Sheikh Zayed Institute of Pediatric Surgical Innovation. “We are able to attach the camera to a surgical microscope and process a significant amount of information from the patient while in the operating room. Not only could this lead to more complete tumor resection, it will also allow the surgeon to save as much healthy brain tissue as possible and reduce lifelong neurological complications.”

Why we’re excited

Brain tumors are the most common solid tumors in children, accounting for the highest number of pediatric cancer deaths globally each year. To develop a treatment plan, neurosurgeons need to understand the tumor’s features, including its type, grade of malignancy, location and its categorization as a primary or metastatic cancer. This information leads to decisions about how to remove or biopsy a tumor.

Under the current protocols, surgeons evaluate tumor margins in the operating room by examining the appearance of the brain tissue and sending out small samples to the pathology department for biopsies. This can lead to longer surgeries and difficult real-time surgical decisions. For instance, some low-grade tumors are visually indistinguishable from healthy brain tissue.

In four investigational cases approved by the hospital’s institutional research board, the sHSI camera was used in the operating room to help segment healthy pediatric brain tissue from tumors. Unlike the conventional red-green-blue (RGB) imaging cameras, which use only those three colors, HSI captures spectral data at each pixel of the image — a task too complex for the human eye — and sends it instantly for processing by an algorithm designed to assist in tumor segmentation.

What’s ahead

Despite the small dataset, the researchers were able to successfully segment healthy brain tissue from lesions with a high specificity during pediatric brain tumor resection procedures. Significant work remains to refine the technology and the machine learning behind it. Researchers also plan to integrate the sHSI camera into a laparoscope to visualize tumors that are not on the brain’s surface and collect data from more angles.

“As we develop these groundbreaking tools, we plan to continue to expand the dataset and refine the algorithm to make pediatric neurosurgery continually more precise,” said Naomi Kifle, M.S., research and development engineer at Children’s National and first author on the paper. “As our dataset grows, we hope to create a model that can distinguish healthy brain tissue, tumor and skull. This groundbreaking surgical tool shows significant promise.”

Winners of the International Conference on Medical Image Computing and Computer Assisted Intervention

AI team wins international competition to measure pediatric brain tumors

Winners of the International Conference on Medical Image Computing and Computer Assisted Intervention
Children’s National Hospital scientists won first place in a global competition to use artificial intelligence (AI) to analyze pediatric brain tumor volumes, demonstrating the team’s ground-breaking advances in imaging and machine learning.

During the International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI), the Children’s National team demonstrated the most accurate algorithm to study the volume of brain tumors – the most common solid tumors affecting children and adolescents and a leading cause of disease-related death at this young age. The technology could someday help oncologists understand the extent of a patient’s disease, quantify the efficacy of treatments and predict patient outcomes.

“The Brain Tumor Segmentation Challenge inspires leaders in medical imaging and deep learning to try to solve some of the most vexing problems facing radiologists, oncologists, computer engineers and data scientists,” said Marius George Linguraru, D.Phil., M.A., M.Sc., the Connor Family Professor in Research and Innovation and principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation. “I am honored that our team won, and I’m even more thrilled for our clinicians and their patients, who need us to keep moving forward to find new ways to treat pediatric brain tumors.”

Why we’re excited

With roughly 4,000 children diagnosed yearly, pediatric brain tumors are consistently the most common type of pediatric solid tumor, second only to leukemia in pediatric malignancies. At the urging of Linguraru and one of his peers at the Children’s Hospital of Philadelphia, pediatric data was included in the international competition for the first time, helping to ensure that children are represented in medical and technological advances.

The contest required participants to use data from multiple institutions and consortia to test competing methods fairly. The Children’s National team created a method to tap into the power of two types of imaging and machine learning: 3D convolutional neural network and 3D Vision Transformer-based deep learning models. They identified regions of the brain affected by tumors, made shrewd data-processing decisions driven by the team’s experience in AI for pediatric healthcare and achieved state-of-the-art results.

The competition drew 18 teams who are leaders from across the AI and machine learning community. The runner-up teams were from NVIDIA and the University of Electronic Science and Technology of China.

The big picture

“Children’s National has an all-star lineup, and I am thrilled to see our scientists recognized on an international stage,” said interim Executive Vice President and Chief Academic Officer Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer for Immunology Research. “As we work to attack brain tumors from multiple angles, we continue to show our exceptional ability to create new and better tools for diagnosing, imaging and treating these devastating tumors.”

Patient and doctor demoing Rare-CAP technology

M.D. in your pocket: New platform allows rare disease patients to carry medical advice everywhere

When someone has a rare disease, a trip to the emergency room can be a daunting experience: Patients and their caregivers must share the particulars of their illness or injury, with the added burden of downloading a non-specialist on the details of a rare diagnosis that may change treatment decisions.

Innovators at Children’s National Hospital and Vanderbilt University Medical Center, supported by Takeda, are trying to simplify that experience using a new web-based platform called the Rare Disease Clinical Activity Protocols, or Rare-CAP. This revolutionary collection of medical information allows patients to carry the latest research-based guidance about their rare disorders in their phones, providing a simple QR code that can open a trove of considerations for any medical provider to evaluate as they work through treatment options for someone with an underlying rare disease.

“No one should worry about what happens when they need medical help, especially patients with rare diseases,” said Debra Regier, M.D., division chief of Genetics and Metabolism at Children’s National and Rare-CAP’s lead medical advisor. “We built this new tool because I have watched as my patient-families have wound up in an emergency room — after all, kids get sprains or fractures — but they don’t have the expertise of a rare disease specialist with them. My hope is that they’re going to pull out their phones and access Rare-CAP, which will explain their rare disease to a new provider who can provide more thoughtful and meaningful care.”

The big picture

A rare disease is defined as any disorder that affects less than 200,000 people in the United States. Some 30 million Americans are believed to be living with one of the 7,000 known rare disorders tracked by the National Organization of Rare Diseases (NORD). Led by Dr. Regier, the Rare Disease Institute at Children’s National is one of 40 NORD centers for excellence in the country that provide care, guidance and leadership for the wide array of disorders that make up the rare disease community.

While a key goal of Rare-CAP is to bolster patient self-advocacy, the platform will also allow medical providers to proactively search for protocols on rare diseases when they know they need specialized advice from experts at Children’s National, a network of tertiary care centers and patient organizations.

As a leading values-based, R&D-driven biopharmaceutical company, Takeda has committed $3.85 million to the project to help activate meaningful change and empower a brighter future for rare disease communities, providing a unique understanding of the struggle that patients and caregivers face when they need care.

“Our team, alongside the medical and rare disease community, saw the need for a single portal to collect standardized care protocols, and we are thrilled to see this innovative tool come to life,” said Tom Koutsavlis, M.D., head of U.S. Medical Affairs at Takeda. “People with rare diseases and their caregivers need faster access to authoritative medical information that providers anywhere can act on, this will lead to improving the standard of care, accelerating time to diagnosis and breaking down barriers to increase equitable access.”

The patient benefit

The creators of Rare-CAP imagined its use in a wide range of settings, including emergency rooms, surgical suites, dental offices, urgent care offices and school clinics. The platform will eventually profile thousands of rare diseases and lay out the implications for care, while also creating a dynamic conversation among users who can offer updates based on real-world experience and changes in medical guidance.

“Our patients are unique, and so is this tool,” Dr. Regier said. “As we roll out Rare-CAP, we believe it is just the beginning of the conversation to expand the platform and see its power for the patient and provider grow, with each entry and each new rare disease that’s added to the conversation.”

A new way to treat pediatric gliomas with BRAF V600 mutations

model of the brain

Gliomas account for 45% of all pediatric tumors of the central nervous system.

Gliomas, which can be classified according to histologic grade as high or low grade, account for 45% of all pediatric tumors of the central nervous system. Detection of the BRAF V600E mutation in pediatric low-grade glioma has been associated with a lower response to standard chemotherapy. In previous trials, dabrafenib (both as monotherapy and in combination with trametinib) has shown efficacy in recurrent pediatric low-grade glioma with BRAF V600 mutations, findings that researchers found warrant further evaluation of this combination as first-line therapy.

The big picture

In a recent study published in the New England Journal of Medicine, experts found that among a randomized cohort of 110 children with low-grade glioma with BRAF V600 mutations, dabrafenib plus trametinib resulted in significantly more responses, longer progression-free survival and a better safety profile than standard chemotherapy as first-line therapy.

“For the past 20 to 30 years, the only effective safe therapy was chemotherapy. In older children, radiation can also be effective, but there’s reluctance on using radiation on a developing brain,” said Roger Packer, M.D., director of the Brain Tumor Institute at Children’s National Hospital and co-author of the study. “As we learned the specific molecular genetic makeups of these tumors, either high- or low-grade gliomas, we found it to be effective to use molecular therapies. These are safer and more effective than chemotherapy alone.”

Dr. Packer also added that there’s approval from the FDA, proving that the industry sees value in investing in pediatrics.

Why it matters

This randomized trial shows the superiority of dabrafenib plus trametinib as a first systemic therapy for pediatric patients with low-grade glioma with BRAF V600 mutations as compared with carboplatin plus vincristine, the standard chemotherapy approach. This benefit was evident in the higher independently determined response, longer progression-free survival and better side-effect profile as reflected in the lower frequency of treatment discontinuation because of toxicity.

“Children treated with a molecular targeted therapy could safely tolerate the therapy and had better outcomes than children who were treated with chemotherapy,” Dr. Packer added.

Overall, these findings show the value of early molecular testing in children with low-grade glioma to determine the presence or absence of BRAF V600 mutations.

New telemedicine-based behavioral intervention program eases pain of patients with SCD

Sickle Cell Anemia 3D Illustration

Telemedicine-based behavioral interventions can reduce pain-related functional impairment in youth with SCD.

Sickle cell disease (SCD) pain is often associated with functional impairment and treatment is often limited to pharmacological approaches with unwanted side effects. Behavioral interventions are common for non-SCD pain populations, but interventions designed to address pain-related impairment in SCD are lacking.

In a recent study published in Pediatric Blood & Cancer, researchers conducted a pilot of a 4-week behavioral pain intervention for youth with SCD delivered via telemedicine known as the Balance Program.

Using an innovative combination of cognitive-behavioral therapy and acceptance-based approaches, researchers found that the intervention was feasible, evidenced by youth and caregiver ratings of high acceptability and satisfaction and excellent treatment completion rates. In addition, youth and their caregivers both reported significant reductions in the degree to which SCD pain interfered with daily activities after the treatment.

What’s been the hold-up in the field?

Researchers and clinicians know that there is a strong psychological component to all experiences of pain and there has been growing evidence in recent decades regarding the effectiveness of behavioral therapies for reducing pain and improving functioning.

“However, sickle cell disease presents unique challenges because unlike many pain presentations, it is common for patients with sickle cell disease to experience both acute and chronic pain, making treatment recommendations less clear,” said Megan Connolly, Ph.D., psychologist at Children’s National Hospital and the study’s lead author. “Previous studies have rarely focused on reducing pain-related disability, which is important for optimizing quality of life.”

How does this work move the field forward?

This study demonstrated the feasibility and acceptability of a telemedicine-based behavioral intervention to reduce pain-related functional impairment in youth with SCD. Nearly all youth and their caregivers rated the intervention as moderately or highly acceptable and 90% of patients completed the full treatment program.

“Moreover, the Balance Program resulted in significant reductions in the extent to which sickle cell disease pain interfered with daily activities,” Dr. Connolly added.

What about the findings is exciting?

This research explains what experts can be doing to reduce the impact of pain on the lives of children and adolescents with SCD. Through their findings, researchers learned that a telemedicine-based behavioral pain intervention, which is often more convenient for families than traveling to the hospital for weekly visits, can meaningfully reduce the impact of pain on daily living.

“It is one thing to develop a program that you think will be helpful, but it’s another thing to develop a program that families will be interested in and doesn’t add unnecessary stress to their lives,” Dr. Connolly said. “Although this study had a relatively small sample, I was also excited to see the magnitude of improvements in pain-related impairment, which was quite large. We plan to continue refining this treatment based on patient and caregiver feedback and looking for ways to increase accessibility to these types of treatments for sickle cell disease pain.”

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.”

Researchers publish first-ever atlas of cancerous mutations in histones

Leading genetic researchers at Children’s National Hospital have published the first pan-cancer atlas of key mutations that can drive molecular changes leading to tumors, creating a roadmap that could lead to new treatments for brain tumors and other cancers.

The research – published in npj Genomic Medicine – presents the first-of-its-kind atlas of histone mutations across pediatric, adolescent/young adult and adult cancers. The novel genetic work offers a framework allowing specific cancers to be redefined in the context of changes in histones, which are essential proteins that provide the structural support for chromosomes.

The big picture

“One of the major challenges that we face every day with pediatric, aggressive tumors, including pediatric high-grade gliomas, is that these tumors grow fast. Doctors often have to give patients 9 to 12 months from diagnosis,” said Javed Nazarian, Ph.D., scientific director of the Brain Tumor Institute at Children’s National and principal investigator at the Center for Genetic Medicine Research. “Children’s National has put together a team of clinicians that are truly devoted to finding a therapy for pediatric high-grade gliomas and aggressive pediatric brain tumors. Our dedicated team empowers translational research, from bench to bedside and reverse translation.”

In 2023, the American Cancer Society estimates that 9,910 children under age 15 will be diagnosed with cancer, making it the second leading cause of death among children. Because of treatment advances, 85% will survive, but many will be left with lifelong disabilities from their treatment. Nazarian and his team believe that identifying the underlying molecular alterations leading to cancers will be essential to finding new therapies that extend life expectancies and preserve quality of life.

The fine print

Histones are essential cellular structures, which prevent DNA from getting tangled. Nazarian and other researchers are investigating whether errors in histones could lead to cancers, including high-grade gliomas and other particularly sinister tumors that can strike young children. By mapping the mutations of the histone-encoding genes, Nazarian and his team believe they can find the drivers of tumors in many pediatric and adult cancers. In studying more than 12,000 tumors for the pan-cancer atlas, they cataloged patient ages, survival outcomes and tumor locations to reveal important trends among different cancers.

Overall, the team found that 11% of tumors had somatic histone mutations, with the highest rates observed among chondrosarcoma, a type of bone cancer (67%); pediatric high-grade glioma, a type of cancer that attacks glial cells in the brain and spinal cord (>60%); and lymphoma, a category of cancers in the lymph system (>30%).

“I think one implication of our study is that we are looking at the epigenomic changes of these mutations in a new light,” Nazarian said. “These mutations are not just specific to a particular tumor type, but they are indeed across a large spectrum of cancer types, and they come in different flavors that could potentially show a new avenue for treatments.”
