Making healthcare innovation for children a priority

Dr. Kurt Newman in front of the capitol building

Recently, Kurt Newman, M.D., president and CEO of Children’s National Hospital, authored an opinion piece for the popular political website, The Hill. In the article, he called upon stakeholders from across the landscape to address the significant innovation gap in children’s healthcare versus adults.

As Chair of the Board of Trustees of the Children’s Hospital Association,  Dr. Newman knows the importance of raising awareness among policy makers at the federal and state level about the healthcare needs of children. Dr. Newman believes that children’s health should be a national priority that is addressed comprehensively. With years of experience as a pediatric surgeon, he is concerned by the major inequities in the advancements of children’s medical devices and technologies versus those for adults. That’s why Children’s National is working to create collaborations, influence policies and facilitate changes that will accelerate the pace of pediatric healthcare innovation for the benefit of children everywhere. One way that the hospital is tackling this challenge is by developing the Children’s National Research & Innovation Campus, which will be the nation’s first innovation campus focused on pediatric research.

Clinical Trial Spotlight: Searching for effective therapies for malignant peripheral nerve sheath tumors

Malignant peripheral nerve sheath tumors

Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas and the most common malignancy associated with neurofibromatosis type 1 (NF1).

Malignant peripheral nerve sheath tumors (MPNST) are aggressive soft tissue sarcomas and the most common malignancy associated with neurofibromatosis type 1 (NF1). Half of all MPNST are seen in NF1 patients, and MPNST is a leading cause of mortality in young patients with NF1. Researchers led by AeRang Kim, M.D., Ph.D., a pediatric oncologist at Children’s National Hospital, are now searching for a medical treatment for this rare disease that currently has dismal survival rates.

“Through consortia efforts, we’ve been able to open and accrue in single histology trials of really rare diseases such as MPNST for which there are no known curative therapies other than surgery, and surgery is very difficult or not feasible in many patients,” says Dr. Kim, the principle investigator for the SARC031 trial sponsored by the Sarcoma Alliance for Research through Collaboration. “In this trial in particular, our hope is to find a new therapy that will benefit patients with MPNST for which we have no known effective medical therapies.”

Using a combination of drugs that target specific pathways involved in MPNST growth, Dr. Kim and colleagues at four other institutions offering the SARC031 trial will monitor patients to see if the drugs shrink, slow down or stop the growth of MPNSTs. Based on preclinical data demonstrating substantial MPNST shrinkage in mice treated with a combination of MEK and mTOR inhibitors, SARC031 is a trial of the MEK inhibitor selumetinib in combination with the mTOR inhibitor sirolimus for patients with unresectable or metastatic MPNST. The primary objective is to determine the clinical benefit of the combination.

Research & Innovation Campus

Children’s National partners with Virginia Tech

Children’s National Hospital and Virginia Tech create formal partnership that includes the launch of a Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus.

Children’s National Hospital and Virginia Tech recently announced a formal partnership that will include the launch of a 12,000-square-foot Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus. The campus is an expansion of Children’s National that is located on a nearly 12-acre portion of the former Walter Reed Army Medical Center in Washington, D.C. and is set to open its first phase in December 2020. This new collaboration brings together Virginia Tech, a top tier academic research institution, with Children’s National, a U.S. News and World Report top 10 children’s hospital, on what will be the nation’s first innovation campus focused on pediatric research.

Research & Innovation Campus

“Virginia Tech is an ideal partner to help us deliver on what we promised for the Children’s National Research & Innovation Campus – an ecosystem that enables us to accelerate the translation of potential breakthrough discoveries into new treatments and technologies,” says Kurt Newman, M.D., president and CEO, Children’s National. “Our clinical expertise combined with Virginia Tech’s leadership in engineering and technology, and its growing emphasis on biomedical research, will be a significant advance in developing much needed treatment and cures to save children’s lives.”

Earlier this year, Children’s National announced a collaboration with Johnson & Johnson Innovation LLC to launch JLABS @ Washington, DC at the Research & Innovation Campus. The JLABS @ Washington, DC site will be open to pharmaceutical, medical device, consumer and health technology companies that are aiming to advance the development of new drugs, medical devices, precision diagnostics and health technologies, including applications in pediatrics.

“We are proud to welcome Virginia Tech to our historic Walter Reed campus – a campus that is shaping up to host some of the top minds, talent and innovation incubators in the world,” says Washington, D.C. Mayor Muriel Bowser. “The new Children’s National Research & Innovation Campus will exemplify why D.C. is the capital of inclusive innovation – because we are a city committed to building the public and private partnerships necessary to drive discoveries, create jobs, promote economic growth and keep D.C. at the forefront of innovation and change.”

Faculty from the Children’s National Research Institute and the Fralin Biomedical Research Institute at Virginia Tech Carilion (VTC) have worked together for more than a decade, already resulting in shared research grants, collaborative publications and shared intellectual property. Together, the two institutions will now expand their collaborations to develop new drugs, medical devices, software applications and other novel treatments for cancer, rare diseases and other disorders.

“Joining with Children’s National in the nation’s capital positions Virginia Tech to improve the health and well-being of infants and children around the world,” says Virginia Tech President Tim Sands, Ph.D. “This partnership resonates with our land-grant mission to solve big problems and create new opportunities in Virginia and D.C. through education, technology and research.”

The partnership with Children’s National adds to Virginia Tech’s growing footprint in the Washington D.C. region, which includes plans for a new graduate campus in Alexandria, Va. with a human-centered approach to technological innovation. Sands said the proximity of the two locations – just across the Potomac – will enable researchers to leverage resources, and will also create opportunities with the Virginia Tech campus in Blacksburg, Va. and the Virginia Tech Carilion Health Science and Technology campus in Roanoke, Va.

Carilion Clinic and Children’s National have an existing collaboration for provision of certain specialized pediatric clinical services. The more formalized partnership between Virginia Tech and Children’s National will drive the already strong Virginia Tech-Carilion Clinic partnership, particularly for children’s health initiatives and facilitate collaborations between all three institutions in the pediatric research and clinical service domains.

Children’s National and Virginia Tech will engage in joint faculty recruiting, joint intellectual property, joint training of students and fellows, and collaborative research projects and programs according to Michael Friedlander, Ph.D., Virginia Tech’s vice president for health sciences and technology, and executive director of the Fralin Biomedical Research Institute at VTC.

“The expansion and formalization of our partnership with Children’s National is extremely timely and vital for pediatric research innovation and for translating these innovations into practice to prevent, treat and ultimately cure nervous system cancer in children,” says Friedlander, who has collaborated with Children’s National leaders and researchers for more than 20 years. “Both Virginia Tech and Children’s National have similar values and cultures with a firm commitment to discovery and innovation in the service of society.”

“Brain and other nervous system cancers are among the most common cancers in children (alongside leukemia),” says Friedlander. “With our strength in neurobiology including adult brain cancer research in both humans and companion animals at Virginia Tech and the strength of Children’s National research in pediatric cancer, developmental neuroscience and intellectual disabilities, this is a perfect match.”

The design of the Children’s National Research & Innovation Campus not only makes it conducive for the hospital to strengthen its prestigious partnerships with Virginia Tech and Johnson & Johnson, it also fosters synergies with federal agencies like the Biomedical Advanced Research and Development Authority, which will collaborate with JLABS @ Washington, DC to establish a specialized innovation zone to develop responses to health security threats. As more partners sign on, this convergence of key public and private institutions will accelerate discoveries and bring them to market faster for the benefit of children and adults.

“The Children’s National Research & Innovation Campus pairs an inspirational mission to find new treatments for childhood illness and disease with the ideal environment for early stage companies. I am confident the campus will be a magnet for big ideas and will be an economic boost for Washington DC and the region,” says Jeff Zients, who was appointed chair of the Children’s National Board of Directors effective October 1, 2019. As a CEO and the former director of President Obama’s National Economic Council, Zients says that “When you bring together business, academia, health care and government in the right setting, you create a hotbed for innovation.”

Ranked 7th in National Institutes of Health research funding among pediatric hospitals, Children’s National continues to foster collaborations as it prepares to open its first 158,000-square-foot phase of its Research & Innovation Campus. These key partnerships will enable the hospital to fulfill its mission of keeping children top of mind for healthcare innovation and research while also contributing to Washington D.C.’s thriving innovation economy.

Dr. Yanxin Pei receives prestigious grant from V Foundation for Cancer Research

Xanxin Pei

When asked about this award, Dr. Pei noted “I am so deeply grateful to receive this support from the V Foundation for Cancer Research…I will use these resources to aid our goal of discovering new therapies to treat medulloblastoma.”

Yanxin Pei, Ph.D., assistant professor in the Brain Tumor Institute and the Children’s Research Institute at Children’s National Hospital in Washington, D.C., has recently been awarded a prestigious grant by the V Foundation for Cancer Research to support her groundbreaking work in finding new treatments for childhood medulloblastoma.

Dr. Pei, who joined Children’s National in 2014 after training in the Wechsler-Reya lab at the Sanford-Burnham Institute in La Jolla, CA, has focused her work on the biology of medulloblastoma, the most common malignant brain tumor in children, with a major emphasis on the study of the medulloblastoma subtype most resistant to treatment. Children with this form of medulloblastoma have less than a 30% chance of survival five years from their diagnosis.

Having already developed one of the most important mouse models of this disease, Dr. Pei’s present V Foundation for Cancer Research Award, which includes becoming a V scholar, will explore the role of metabolism in the development of metastasis in MYC-amplified medulloblastomas (the most virulent form of medulloblastoma).

The V Foundation for Cancer Research Award is one of a series of prestigious awards Dr. Pei has received over the past 18 months for her work, including an NIH-sponsored 5-year award (ROI) evaluating other aspects of medulloblastoma development and resistance to therapy, and grants from the Rally Foundation, the Meghan Rose Bradley Foundation and the Children’s Cancer Foundation.

When asked about this award, Dr. Pei noted “I am so deeply grateful to receive this support from the V Foundation for Cancer Research…I will use these resources to aid our goal of discovering new therapies to treat medulloblastoma.”

Her cutting-edge work is generating national and international attention and firmly places Dr. Pei as an international leader in medulloblastoma research.

Germline microsatellite genotypes differentiate children with medulloblastoma

pastel colored DNA strands

A new study suggests that medulloblastoma-specific germline microsatellite variations mark those at-risk for medulloblastoma development.

Brian Rood, M.D., oncologist and medical director at the Brain Tumor Institute, and Harold “Skip” Garner, Ph.D., associate vice provost for research development at Edward Via College of Osteopathic Medicine, published a report in the Society for Neuro-Oncology’s Neuro-Oncology Journal about using a novel approach to identify specific markers in germline (non-tumor) DNA called microsatellites that can differentiate children who have the brain tumor medulloblastoma (MB) from those who don’t.

“Ultimately, the best way to save children from brain tumors and prevent them from bearing long-term side effects from treatment is to prevent those tumors from occurring in the first place,” says Dr. Rood. “New advancements hold the potential to finally realize the dream of cancer prevention, but we must first identify those children at-risk.”

While analyzing germline sequencing data from a training set of 120 MB subjects and 425 controls, the doctors identified 139 individual microsatellites whose genotypes differ significantly between the groups. Using a genetic algorithm, they were able to construct a subset of 43 microsatellites that distinguish MB subjects from controls with a sensitivity and specificity of 92% and 88% respectively.

“We made discoveries in an untapped part of the human genome, enabled by unique bioinformatics data mining approaches combined with clinical insight,” said Dr. Garner. “Our findings establish new genomic directions that can lead to high accuracy diagnostics for predicting susceptibility to medulloblastoma.”

What the doctors discovered and demonstrated in the study was that MB-specific germline microsatellite variations mark those at risk for MB development and suggest that other mechanisms of cancer predisposition beyond heritable mutations exist for MB.

“This work is the first to demonstrate the ability of specific DNA sequences to differentiate children with cancer from their healthy counterparts,” added Dr. Rood.

Contributing Authors to this research study included:  Brian R. Rood, M.D., Harold R. Garner, Ph.D., Samuel Rivero-Hinojosa, Ph.D., and Nicholas Kinney, Ph.D.

proton center

Johns Hopkins Proton Therapy Center opens in collaboration with Children’s National

proton center

The Center at Sibley offers state-of-the-art, pencil beam proton therapy equipment, as well as next-generation imaging technologies such as dual energy CT-guided treatment that reduces the range of error, and the latest innovation in biomatrix magnetic resonance imaging designed to target moving tumors in organs like the lung and liver.

Pediatric cancer patients in the Greater Washington region now have access to one of the most advanced, lifesaving proton therapy technologies offered in the U.S. The Johns Hopkins Proton Therapy Center opened Oct.28, 2019, at Sibley Memorial Hospital in collaboration with Children’s National Hospital.

The proton collaboration with Children’s National expands an existing collaboration between Children’s National and Johns Hopkins Medicine that established the pediatric radiation oncology program at Sibley, which treats a wide range of children’s cancer. Now, Sibley will offer the only proton center in the Washington D.C. region with a dedicated pediatric team, staff who are trained in pediatrics instead of adult providers who also treat children.

“This collaboration allows us to bring the latest technology to the region and offer the most advanced cancer treatment to help children live better lives,” says Kurt Newman, M.D., president and CEO at Children’s National. “As one of the Top 10 children’s hospitals in the nation, our goal is to ensure that patients and families are receiving the best care possible.”

The Center at Sibley offers state-of-the-art, pencil beam proton therapy equipment, as well as next-generation imaging technologies such as dual energy CT-guided treatment that reduces the range of error, and the latest innovation in biomatrix magnetic resonance imaging designed to target moving tumors in organs like the lung and liver. A large mechanical arm called a gantry can move the beam 360 degrees around the patient, treating the tumor from several angles as it destroys tumor cells layer by layer.

“Proton therapy is an advanced technology that allows radiation to be delivered precisely to cancer tissue,” says Jeffrey Dome, M.D., Ph.D., vice president for Cancer and Blood Disorders at Children’s National. “This provides a significant advantage compared with conventional radiation therapy, especially in children, where sparing the healthy tissue that surrounds the tumor may be critical for normal growth and development. Proton therapy shows great promise to reduce long-term side effects of radiation treatment.”

The Center at Sibley will have a fully integrated research room, which will allow clinical, basic science and medical physics faculty to advance clinical trial research, translational research and technology development research in proton therapy. Leading experts and oncologists will study proton outcomes for sarcoma, gynecological tumors, pancreatic and liver tumors, lymph node cancers and tumors located near the heart and major blood vessels, such as lung or breast cancers. In addition, the researchers will examine how the proton energy that kills cancer cells interacts with non-cancerous cells and tissue surrounding the tumors.

The JJohns Hopkins Proton Therapy Center opens in phases. The first treatment room opened October 2019. The second room is scheduled to open in spring 2020, and the third room and fixed beam research room are scheduled to open in fall 2020.

Extracting actionable research data faster, with fewer hassles

Mihailo Kaplarevic

Mihailo Kaplarevic, Ph.D., the newly minted Chief Research Information Officer at Children’s National Hospital and Bioinformatics Division Chief at Children’s National Research Institute, will provide computational support, advice, informational guidance, expertise in big data and data analyses for researchers and clinicians.

Kaplarevic’s new job is much like the role he played most recently at the National Heart, Lung and Blood Institute (NHLBI), assembling a team of researchers and scientists skilled in computing and statistical analyses to assist as in-house experts for other researchers and scientists.

NHLBI was the first institute within the National Institutes of Health (NIH) family to set up a scientific information office. During his tenure, a half-dozen other NIH institutions followed, setting up the same entity to help bridge the enormous gap between basic and clinical science and everything related to IT.

“There is a difference compared with traditional IT support at Children’s National – which will remain in place and still do the same sort of things they have been doing so far,” he says of The Bear Institute for Health Innovation. “The difference is this office has experience in research because every single one of us was a researcher at a certain point in our career: We are published. We applied for grants. We lived the life of a typical scientist. On top of that, we’re coming from the computational world. That helps us bridge the gaps between research and clinical worlds and IT.”

Ultimately, he aims to foster groundbreaking science by recognizing the potential to enhance research projects by bringing expertise acquired over his career and powerful computing tools to help teams achieve their goals in a less expensive and more efficient way.

“I have lived the life of a typical scientist. I know exactly how painful and frustrating it can be to want to do something quickly and efficiently but be slowed by technological barriers,” he adds.

As just one example, his office will design the high-performance computing cluster for the hospital to help teams extract more useful clinical and research data with fewer headaches.

Right now, the hospital has three independent clinical systems storing patient data; all serve a different purpose. (And there are also a couple of research information systems, also used for different purposes.) Since databases are his expertise, he will be involved in consolidating data resources, finding the best way to infuse the project with the bigger-picture mission – especially for translational science – and creating meaningful, actionable reports.

“It’s not only about running fewer queries,” he explains. “One needs to know how to design the right question. One needs to know how to design that question in a way that the systems could understand. And, once you get the data back, it’s a big set of things that you need to further filter and carefully shape. Only then will you get the essence that has clinical or scientific value. It’s a long process.”

As he was introduced during a Children’s National Research Institute faculty meeting in late-September 2019, Kaplarevic joked that his move away from pure computer science into a health care and clinical research domain was triggered by his parents: “When my mom would introduce me, she would say ‘My son is a doctor, but not the kind of doctor who helps other people.’ ”

Some of that know-how will play out by applying tools and methodology to analyze big data to pluck out the wheat (useful data) from the chaff in an efficient and useful way. On projects that involve leveraging cloud computing for storing massive amounts of data, it could entail analyzing the data wisely to reduce its size when it comes back from the cloud – when the real storage costs come in. “You can save a lot of money by being smart about how you analyze data,” he says.

While he expects his first few months will be spent getting the lay of the land, understanding research project portfolios, key principal investigators and the pediatric hospital’s biggest users in the computational domain, he has ambitious longer-term goals.

“Three years from now, I would like this institution to say that the researchers are feeling confident that their research is not affected by limitations related to computer science in general. I would like this place to become a very attractive environment for up-and-coming researchers as well as for established researchers because we are offering cutting-edge technological efficiencies; we are following the trends; we are a secure place; and we foster science in the best possible way by making computational services accessible, affordable and reliable.”

Chromosomes

Precision medicine for Wilms tumor patients

Chromosomes

Previously, researchers discovered that loss of heterozygosity (LOH) on chromosomes 1 and 16 is associated with a significantly increased risk of relapse of Wilms tumor.

About 650 children are diagnosed each year in the U.S. with Wilms tumor, the most common pediatric kidney cancer. The vast majority of patients respond well to the current standard of care involving a combination of surgery, chemotherapy and radiation. However, approximately 20% of patients with “favorable histology” Wilms tumor experience recurrence.

Previously, researchers discovered that loss of heterozygosity (LOH) on chromosomes 1 and 16 is associated with a significantly increased risk of relapse. A research team in the Children’s Oncology Group (COG), led by Jeffrey Dome, M.D., Ph.D., vice president of the Center for Cancer and Blood Disorders at Children’s National Hospital, sought to determine whether an augmented chemotherapy regimen can overcome the negative effect of LOH.

More than 2,500 patients with Wilms tumor were enrolled in the biology and classification study over a 7–year period. Tumor tissue was tested for LOH and patients with LOH at both chromosomes 1 and 16 received more intensive chemotherapy regimens compared to the standard approach. The results showed that the increased treatment provided a statistically significant benefit in the 4-year event-free survival, with trends toward improved overall survival. For low-stage disease (stage I-II), the four-year event-free survival was 87.3%, compared to a historical rate of 68.8%. Similarly, for advanced stage disease (stage III/IV) four-year event-free survival was 90.2%, compared with 61.3% historically.

Although the new regimens involved additional chemotherapy agents compared to the standard regimens, the short-term toxicities were expected and manageable. There is an increased risk of long-term toxicity including infertility and second malignancies, which requires careful discussion with families. Future studies will seek to mitigate these risks with newer chemotherapy agents.

By better understanding which patients might benefit from more intensive treatment regimens through precision medicine, doctors can tailor therapy according to the risk of relapse, Dr. Dome says.

“This study represents a significant milestone in the treatment of Wilms tumor because it is the first to demonstrate that patient outcome can be improved using a molecular biomarker to guide treatment,” he explains. “We have entered the age of precision medicine for Wilms tumor.”

Lee Beers

Getting to know Lee Beers, M.D., FAAP, future president-elect of AAP

Lee Beers

Lee Savio Beers, M.D., FAAP, Medical Director of Community Health and Advocacy at the Child Health Advocacy Institute (CHAI) at Children’s National Hospital carved out a Monday morning in late-September 2019, as she knew the American Academy of Pediatrics (AAP) would announce the results of its presidential election, first by telephone call, then by an email to all of its members.  Her husband blocked off the morning as well to wait with her for the results.  She soon got the call that she was elected by her peers to become AAP president-elect, beginning Jan. 1, 2020. Dr. Beers will then serve as AAP president in 2021 for a one-year term.

That day swept by in a rush, and then the next day she was back in clinic, caring for her patients, some of them teenagers whom she had taken care of since birth. Seeing children and families she had known for such a long time, some of whom had complex medical needs, was a perfect reminder of what originally motivated Dr. Beers to be considered as a candidate in the election.

“When we all work together – with our colleagues, other professionals, communities and families – we can make a real difference in the lives of children.  So many people have reached out to share their congratulations, and offer their support or help. There is a real sense of collaboration and commitment to child health,” Dr. Beers says.

That sense of excitement ripples through Children’s National.

“Dr. Beers has devoted her career to helping children. She has developed a national advocacy platform for children. I can think of no better selection for the president-elect role of the AAP. She will be of tremendous service to children within AAP national leadership,” says Kurt Newman, M.D., Children’s National Hospital President and CEO.

AAP comprises 67​,000 pediatricians, and its mission is to promote and safeguard the health and well-being of all children – from infancy to adulthood.

The daughter of a nuclear engineer and a schoolteacher, Dr. Beers knew by age 5 that she would become a doctor. Trained as a chemist, she entered the Emory University School of Medicine after graduation. After completing residency at the Naval Medical Center, she became the only pediatrician assigned to the Guantanamo Bay Naval Station.

That assignment to Cuba, occurring so early in her career, turned out to be a defining moment that shapes how she partners with families and other members of the team to provide comprehensive care.

“I was a brand-new physician, straight out of residency, and was the only pediatrician there so I was responsible for the health of all of the kids on the base. I didn’t know it would be this way at the time, but it was formative. It taught me to take a comprehensive public health approach to taking care of kids and their families,” she recalls.

On the isolated base, where she also ran the immunization clinic and the nursery, she quickly learned she had to judiciously use resources and work together as a team.

“It meant that I had to learn how to lead a multi-disciplinary team and think about how our health care systems support or get in the way of good care,” she says.

One common thread that unites her past and present is helping families build resiliency to shrug off adversity and stress.

“The base was a difficult and isolated place for some families and individuals, so I thought a lot about how to support them. One way is finding strong relationships where you are, which was important for patients and families miles away from their support systems. Another way is to find things you could do that were meaningful to you.”

Cuba sits where the Atlantic Ocean, Caribbean Sea and Gulf of Mexico meet. Dr. Beers learned how to scuba dive there – something she never would have done otherwise – finding it restful and restorative to appreciate the underwater beauty.

“I do think these lessons about resilience are universal. There are actually a lot of similarities between the families I take care of now, many of whom are in socioeconomically vulnerable situations, and military families when you think about the level of stress they are exposed to,” she adds.

Back stateside in 2001, Dr. Beers worked as a staff pediatrician at the National Naval Medical Center in Bethesda, Maryland, and Walter Reed Army Medical Center in Washington, D.C. In 2003, Dr. Beers joined Children’s National Hospital as a general pediatrician in the Goldberg Center for Community Pediatric Health. Currently, she oversees the DC Collaborative for Mental Health in Pediatric Primary Care, a public-private coalition that elevates the standards of mental health care for all children, and is Co-Director of the Early Childhood Innovation Network. She received the Academic Pediatric Association’s 2019 Public Policy and Advocacy Award.

As a candidate, Dr. Beers pledged to continue AAP’s advocacy and public policy efforts and to further enhance membership diversity and inclusion. Among her signature issues:

  • Partnering with patients, families, communities, mental health providers and pediatricians to co-design systems to bolster children’s resiliency and to alleviate growing pediatric mental health concerns
  • Tackling physician burnout by supporting pediatricians through office-based education and systems reforms
  • Expanding community-based prevention and treatment

“I am humbled and honored to have the support of my peers in taking on this newest leadership role,” says Dr. Beers. “AAP has been a part of my life since I first became a pediatrician, and my many leadership roles in the DC chapter and national AAP have given me a glimpse of the collective good that pediatricians can accomplish by working together toward common strategic goals.”

AAP isn’t just an integral part of her life, it’s where she met her future husband, Nathaniel Beers, M.D., MPA, FAAP, President of The HSC Health Care System. The couple’s children regularly attended AAP meetings with them when they were young.

Just take a glimpse at Lee Beers’ Twitter news feed. There’s a steady stream of images of her jogging before AAP meetings to amazing sunrises, jogging after AAP meetings to stellar sunsets and always, always, images of the entire family, once collectively costumed as The Incredibles.

“I really do believe that we have to set an example: If we are talking about supporting children and families in our work, we have to set that example in our own lives. That looks different for everyone, but as pediatricians and health professionals, we can model prioritizing our families while still being committed to our work,” she explains.

“Being together in the midst of the craziness is just part of what we do as a family. We travel a lot, and our kids have gone with us to AAP meetings since they were infants. My husband even brought our infant son to a meeting at the mayor’s office when he was on paternity leave. Recognizing that not everyone is in a position to be able to do things like that, it’s important for us to do it – to continue to change the conversation and make it normal to have your family to be part of your whole life, not have a separate work life and a separate family life.”

A melanoma drug shows promise for NF1 plexiforms

Dr. Bornhorst talks with her patient Maddox Gibson,

Dr. Bornhorst talks with her patient Maddox Gibson, who is part of the compassionate use trial of selumentinib for which she serves as site principal investigator.

A class of drugs originally approved for stopping tumor growth in adult cancers including melanoma and small cell lung cancer may be the key to treating plexiform neurofibromas in neurofibromatosis type 1 (NF1), too. If effective, doctors will finally have a treatment to offer for children with complicated plexiform neurofibromas that can’t be removed via surgery.

These drugs, including selumentinib, work by inhibiting the activity of the mitogen-activated protein kinase enzymes MEK1 and MEK2. The enzymes have a direct impact on the activity of the cellular signaling pathway MAPK/ERK, which can be overactive some cancers.

Ongoing pre-clinical studies made possible by national and international neurofibromatosis research collaborations demonstrated that this same pathway is overactive in children with NF1 who have plexiform neurofibromas. The compelling findings from these studies set the stage for clinical trials to test the safety and efficacy of selumetinib and other MEK inhibitors as a therapy for pediatric NF1 patients with inoperable plexiform neurofibromas.

At Children’s National, these studies are run by clinicians such as Miriam Bornhorst, M.D., clinical director of the Gilbert Family Neurofibromatosis Institute and Aerang Kim, M.D., Ph.D. Children’s is one of only four sites in the United States to participate in a National Institutes of Health-led clinical trial to study the use of selumetinib in NF1. Dr. Kim is the site principal investigator and Dr. Bornhorst serves as co-principal investigator on phase 2 of the trial.

“Any time we find a medication that works with NF1, we’re excited, especially because for so many years, we didn’t have any of these options for these families,” Dr. Bornhorst says. “We’re offering something these families have never had before – a treatment that may stop growth and maybe even keep these tumors from returning. It means we’re doing more than managing symptoms – we’re really treating them.”

NF1 affects a relatively small number of people, particularly children. However, researchers and clinicians who are dedicated to the condition have banded together via collaborations and consortia to fuel research and development of new therapies across multiple institutions in the U.S. and abroad.

“Patients come to see me who’ve been at our clinic for years and I’ll talk about MEK inhibitors, and they are just shocked to hear there may be a new option,” Dr. Bornhorst says.

The NIH trial continues to collect data at four U.S. centers, with the ultimate goal of submitting the results for FDA review. Additional data is also collected from patients who didn’t qualify for the trial but who received the drug for compassionate use, an effort led by Dr. Bornhorst. The information collected from that compassionate use trial also helps investigators make the case to broaden the eligibility criteria for future trials.

“The medications are showing that they work,” Dr. Bornhorst notes. “Now we need to determine how to identify the patients who we know will need these therapies.”

To meet that need, other studies, led by both Dr. Bornhorst and Dr. Kim, seek radiographic and blood biomarkers that will identify children with NF1 who are more likely to develop plexiform neurofibromas, and whose plexiforms may progress to something malignant.

Protein-coding genes comprise a mere 1% of DNA. While the other 99% of DNA was once derided as “junk,” it has become increasingly apparent that some non-coding genes enable essential cellular functions.

Wei Li, Ph.D., a principal investigator in the Center for Genetic Medicine Research at Children’s National in Washington, D.C., proposes to develop statistical and computational methods that sidestep existing hurdles that currently complicate genome-wide CRISPR/Cas9 screening. The National Institutes of Health has granted him $2.23 million in funding over five years to facilitate the systematic study of genes, non-coding elements and genetic interactions in various biological systems and disease types.

Right now, a large volume of screening data resides in the public domain, however it is difficult to compare data that is stored in one library with data stored at a different library. Over the course of the five-year project, Li aims to:

  • Improve functional gene identification from CRISPR screens.
  • Develop new analyses algorithms for screens targeting non-coding elements.
  • Study genetic interactions from CRISPR screens targeting gene pairs.

Ultimately, Li’s work will examine a range of disease types. Take cancer.

“There is abundant information already available in the public domain, like the Project Achilles  from the Broad Institute. However, no one is looking to see what is going in inside these tumors,” Li says. “Cancer is a disease of uncontrolled cell growth that makes tumors grow faster.”

Li and colleagues are going to ask which genes control this process by looking at genes that hit the brakes on cell growth as well as genes that pump the gas.

“You knock out one gene and then look: Does the cell grow faster or does it grow more slowly? If the cell grows more slowly, you know you are knocking out a gene that has the potential to stop tumor growth. If cells are growing faster, you know that you’re hitting genes that suppress cancer cell growth.”

In a nutshell, CRISPR (clustered regularly interspaced short palindromic repeats) screens knock out different genes and monitor changes in corresponding cell populations. When CRISPR first became popular, Li decided he wanted to do something with the technology. So, as a Postdoc at Harvard, he developed comprehensive computational algorithms for functional screens using CRISPR/Cas9.

To reach as many people as possible, he offered that MAGeCK/MAGeCK-VISPR software free to as many researchers as possible, providing source code and offering internet tutorials.

“So far, I think there are quite a lot of people using this. There have been more than 40,000 software downloads,” he adds. “It’s really exciting and revolutionary technology and, eventually, we hope the outcomes also will be exciting. We hope to find something really helpful for cancer patients.”

Epstein Barr virus

Fighting lymphoma with targeted T-cells

Epstein-Barr virus

The Epstein-Barr virus (EBV) is best known as the cause of mononucleosis, the ubiquitous “kissing disease” that most people contract at some point in their life. But in rare instances, this virus plays a more sinister role as the impetus of lymphomas, cancers that affect the white blood cells known as lymphocytes.

The Epstein-Barr virus (EBV) is best known as the cause of mononucleosis, the ubiquitous “kissing disease” that most people contract at some point in their life. But in rare instances, this virus plays a more sinister role as the impetus of lymphomas, cancers that affect the white blood cells known as lymphocytes. EBV-associated lymphomas account for about 40% of Hodgkin lymphomas, 20% of diffuse large B-cell lymphomas, and more than 90% of natural killer/T-cell lymphomas. This latter type of lymphoma typically has a very poor prognosis even with the “standard of care” lymphoma treatments such as chemotherapy and/or radiation.

When these interventions fail, the only curative approach is an allogeneic  hematopoietic stem cell transplant from a healthy donor, a treatment that’s tough on patients’ bodies and carries significant risks, says Lauren P. McLaughlin, M.D., a pediatrician specializing in hematology and oncology at Children’s National in Washington, D.C. Patients who receive these allogenic transplants are immune-compromised until the donor cells engraft; the grafts can attack patients’ healthy cells in a phenomenon called graft versus host disease; and if patients relapse or don’t respond to this treatment, few options remain.

To help improve outcomes, Dr. McLaughlin and colleagues tested an addition to the allogeneic hematopoietic stem cell transplant procedure for patients with EBV-associated lymphomas: infusion of a type of immune cell called T cells specifically trained to fight cells infected with EBV.

Dr. McLaughlin, along with Senior Author Catherine M. Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research and the Program for Cell Enhancement and Technologies for Immunotherapy at Children’s National, and colleagues tested this therapy in 26 patients treated at Children’s National or Baylor College of Medicine. They published these results online on Sept. 27, 2018, in the journal Blood. The study was a Phase I clinical trial, meaning that the therapy was tested primarily for safety, with efficacy as a secondary aim.

Seven patients who received the therapy had active disease that had not responded to conventional therapies. The other 19 were patients deemed to be at high risk for relapse.

Before each patient received their stem cell transplant, their donors gave an additional blood sample to generate the cancer-fighting T cells. Over the next 8 to 10 weeks, the researchers painstakingly manufactured the immune cells known as T-cells that specifically targeted EBV, growing these cells into numbers large enough for clinical use. Then, as early as 30 days after transplant, the researchers infused these T-cells into patients administering at least two doses, spaced two weeks apart.

Over the next several weeks, the researchers at CNMC and Baylor College of Medicine monitored patients with comprehensive exams to see how they fared after these transplants. The results showed that adverse effects from the treatment were exceedingly rare. There were no immediate infusion-related toxicities to the T-cell therapy and only one incident of dose-limiting toxicity.

This therapy may be efficacious, depending on the individual patients’ circumstances, Dr McLaughlin adds. For those in complete remission but at high risk of relapsing, the two-year survival rate was 78%, suggesting that the administration of this novel T-cell therapy may give the immune system a boost to prevent the lymphoma from returning after transplant. For patients with active T-cell lymphomas, two-year survival rates were 60%. However, even these lower rates are better than the historical norm of 30-50%, suggesting that the targeted T-cell therapies could help fight disease in patients with this poor prognosis lymphoma.

Dr. McLaughlin, the study’s lead author and a Lymphoma Research Foundation grantee, notes that researchers have more work to do before this treatment becomes mainstream. For example, this treatment will need to be tested in larger populations of patients with EBV-related lymphoma to determine who would derive the most benefit, the ideal dose and dose timing. It also may be possible to extend targeted T-cell treatments like this to other types of cancers. In the future, Dr. McLaughlin adds, it may be possible to develop T-cells that could be used “off the shelf”—in other words, they wouldn’t need to come from a matched donor and would be ready to use whenever a recipient needs them. Another future goal is using this therapy as one of the first lines of treatment rather than as a last resort.

“Our ultimate goal is to find a way to avoid chemotherapy and/or radiation therapy while still effectively treating a patient’s cancer,” she says. “Can you use the immune system to do that job? We’re working to answer that question.”

Brenner, Cliona M. Rooney and Helen E. Heslop, all of Baylor College of Medicine; Meng-Fen Wu from the Dan L.

Test tube with DNA

“Liquid biopsies” could track diffuse midline gliomas

Test tube with DNA

A multi-institutional team led by researchers at Children’s National in Washington, D.C., developed and tested “liquid biopsy,” a measure of circulating tumor DNA in patients’ cerebrospinal fluid and blood plasma. They show that quantifying the amount of circulating tumor DNA possessing key mutations characteristic of diffuse midline gliomas could reliably predict the tumors’ response to radiotherapy.

Diffuse midline gliomas are rare, diagnosed in fewer than 800 Americans every year, the majority of whom are children. These cancers arise in the cellular “glue” that holds the brain and spinal cord’s neurons together, grow swiftly and have no cure. About half of patients with these cancers, including diffuse intrinsic pontine glioma, die within one year of diagnosis.

Clinical trials are increasingly investigating new treatments that could offer hope for patients and their families. Yet, thus far, there have been few ways to track the progression of these conditions, offering little insight on whether a treatment is hitting its intended goal.

To solve this problem, a multi-institutional team led by researchers at Children’s National in Washington, D.C., developed and tested “liquid biopsy,” a measure of circulating tumor DNA in patients’ cerebrospinal fluid and blood plasma. They show that quantifying the amount of circulating tumor DNA possessing key mutations characteristic of these cancers could reliably predict the tumors’ response to radiotherapy. The scientists published their results online Oct. 15, 2018, in Clinical Cancer Research.

“We heard from our clinician colleagues that many kids were coming in and their magnetic resonance imaging (MRI) suggested a particular type of tumor. But it was always problematic to identify the tumor’s molecular subtype,” says Javad Nazarian, Ph.D., MSC, a principal investigator in Children’s Center for Genetic Medicine Research. “Our colleagues wanted a more accurate measure than MRI to find the molecular subtype. That raised the question of whether we could actually look at their blood to determine the tumor subtype.”

Children’s liquid biopsy, which remains at the research phase, starts with a simple blood draw using the same type of needle as is used when people donate blood. When patients with brain tumors provide blood for other laboratory testing, a portion of it is used for the DNA detective work. Just as a criminal leaves behind fingerprints, tumors shed telltale clues in the blood. The team at Children’s National searches for the histone 3K27M (H3K27M), a mutation associated with worse clinical outcomes.

“With liquid biopsy, we were able to detect a few copies of tumor DNA that were hiding behind a million copies of healthy DNA,” Nazarian says. “The blood draw and liquid biopsy complement the MRI. The MRI gives the brain tumor’s ZIP code. Liquid biopsy gives you the demographics within that ZIP code.”

Working with collaborators around the nation, Children’s National continues to refine the technology to improve its accuracy.

Even though this research technique is in its infancy, the rapid, cheap and sensitive technology already is being used by people around the globe.

“People around the world are sending blood to us, looking for this particular mutation, H3K27M,” says Lindsay B. Kilburn, M.D., a neurooncologist, principal investigator at Children’s National for the Pacific Pediatric Neuro-Oncology Consortium, and study co-author. “In many countries or centers children to not have access to teams experienced in taking a biopsy of tumors in the brainstem, they can perform a simple blood draw and have that blood processed and analyzed by us. In only a few days, we can provide important molecular information on the tumor subtype previously only available to patients who had undergone a tumor biopsy.”

With that DNA finding, physicians can make more educated therapeutic decisions, including prescribing medications that could not have been given previously, Nazarian adds.

In addition to Nazarian and Dr. Kilburn, study co-authors include Eshini Panditharatna, Madhuri Kambhampati, Heather Gordish-Dressman, Ph.D., Suresh N. Magge, M.D., John S. Myseros, M.D., Eugene I.

Fighting lethal cancer with a one-two punch

The immune system is the ultimate yin and yang, explains Anthony D. Sandler, M.D., senior vice president and surgeon-in-chief of the Joseph E. Robert Jr. Center for Surgical Care at Children’s National in Washington, D.C. With an ineffective immune system, infections such as the flu or diarrheal illness can run unchecked, causing devastating destruction. But on the other hand, excess immune activity leads to autoimmune diseases, such as lupus or multiple sclerosis. Thus, the immune system has “checks and balances” to stay controlled.

Cancer takes advantage of “the checks and balances,” harnessing the natural brakes that the immune system puts in place to avoid overactivity. As the cancer advances, molecular signals from tumor cells themselves turn on these natural checkpoints, allowing cancers to evade immune attack.

Several years ago, a breakthrough in pharmaceutical science led to a new class of drugs called checkpoint inhibitors. These medicines take those proverbial brakes off the immune system, allowing it to vigorously attack malignancies. However, Dr. Sandler says, these drugs have not worked uniformly and in some cancers, they barely work at all against the cancer.

One of these non-responders is high risk neuroblastoma, a common solid tumor found outside the skull in children. About 800 U.S. children are diagnosed with this cancer every year. And kids who have the high-risk form of neuroblastoma have poor prognoses, regardless of which treatments doctors use.

However, new research could lead to promising ways to fight high-risk neuroblastoma by enabling the immune system to recognize these tumors and spark an immune response. Dr. Sandler and colleagues recently reported on these results in the Jan. 29, 2018, PLOS Medicine using an experimental model of the disease.

The researchers created this model by injecting the preclinical models with cancer cells from an experimental version of neuroblastoma. The researchers then waited several days for the tumors to grow. Samples of these tumors showed that they expressed a protein on their cell surfaces known as PD-L1, a protein that is also expressed in many other types of human cancers to evade immune system detection.

To thwart this protective feature, the researchers made a cancer vaccine by removing cells from the experimental model’s tumors and selectively turning off a gene known as Id2. Then, they irradiated them, a treatment that made these cells visible to the immune system but blocked the cells from dividing to avoid new tumors from developing.

They delivered these cells back to the experimental models, along with two different checkpoint inhibitor drugs – antibodies for proteins known as CLTA-4 and PD-L1 – over the course of three treatments, delivered every three days. Although most checkpoint inhibitors are administered over months to years, this treatment was short-term for the experimental models, Dr. Sandler explains. The preclinical models were completely finished with cancer treatment after just three doses.

Over the next few weeks, the researchers witnessed an astounding turnaround: While experimental models that hadn’t received any treatment uniformly died within 20 days, those that received the combined vaccine and checkpoint inhibitors were all cured of their disease. Furthermore, when the researchers challenged these preclinical models with new cancer cells six months later, no new tumors developed. In essence, Dr. Sandler says, the preclinical models had become immune to neuroblastoma.

Further studies on human patient tumors suggest that this could prove to be a promising treatment for children with high-risk neuroblastoma. The patient samples examined show that while tumors with a low risk profile are typically infiltrated with numerous immune cells, tumors that are high-risk are generally barren of immune cells. That means they’re unlikely to respond to checkpoint inhibiting drugs alone, which require a significant immune presence in the tumor microenvironment. However, Dr. Sandler says, activating an immune response with a custom-made vaccine from tumor cells could spur the immune response necessary to make these stubborn cancers respond to checkpoint inhibitors.

Dr. Sandler cautions that the exact vaccine treatment used in the study won’t be feasible for people. The protocol to make the tumor cells immunogenic is cumbersome and may not be applicable to gene targeting in human patients. However, he and his team are currently working on developing more feasible methods for crafting cancer vaccines for kids. They also have discovered a new immune checkpoint molecule that could make this approach even more effective.

“By letting immune cells do all the work we may eventually be able to provide hope for patients where there was little before,” Dr. Sandler says.

In addition to Dr. Sandler, study co-authors include Priya Srinivasan, Xiaofang Wu, Mousumi Basu and Christopher Rossi, all of the Joseph E. Robert Jr. Center for Surgical Care and The Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI), at Children’s National in Washington, D.C.

ID-KD vaccine induced T-cell cytotoxicity

Mechanism of Id2kd Neuro2a vaccination combined with α-CTLA-4 and α-PD-L1 immunotherapy in a neuroblastoma model. During a vaccine priming phase, CTLA-4 blockade enhances activation and proliferation of T-cells that express programmed cell death 1 (PD1) and migrate to the tumor. Programmed cell death-ligand 1 (PD-L1) is up-regulated on the tumor cells, inducing adaptive resistance. Blocking PD-L1 allows for enhanced cytotoxic effector function of the CD8+ tumor-infiltrating lymphocytes. Artist: Olivia Abbate

TAA-Ts as therapy for tumors

Holly Meany

“The T cell immunotherapy regimen resulted in prolonged disease stabilization in patients who previously experienced rapid tumor progression,” says Holly Meany, M.D. “The therapy could prove to be an important component of immunotherapy for patients with solid tumor malignancies.”

In a study published in the Journal of Clinical Oncology, researchers from Children’s National Health System uncovered tumor-associated antigen cytotoxic T cells (TAA-Ts) that represent a new and potentially effective nontoxic therapeutic approach for patients with relapsed or refractory solid tumors.

The Phase 1 study led by Children’s National pediatric oncologists Holly Meany, M.D., and Amy B. Hont, M.D., represented the first in-human trial investigating the safety of administering TAA-Ts that target Wilms Tumor gene 1, a preferentially expressed antigen of melanoma and survivin in patients with relapsed/refractory solid tumors.

“These are exciting clinical results using a novel ‘first in-human’ T cell therapy,” said Catherine Bollard, MB.Ch.B., M.D., director of the Center for Cancer and Immunology Research at Children’s Research Institute. “This T cell therapy was safe and appeared to prolong patients’ time to progression which suggests that we can now use this novel treatment as a combination therapy to hopefully achieve long-term remissions in pediatrics and adults with relapsed/refractory solid tumors.”

During the Phase 1 trial, TAA-Ts products were generated from autologous peripheral blood and were infused over three dose levels. Patients were then eligible for up to eight infusions that were administered four to seven weeks apart.

Of the 15 evaluable patients, 11 were with stable disease or better at 45 days post-infusion and were defined as responders. Patients who were treated at the highest dose level showed the best clinical outcomes, with a 6-month progression-free survival rate of 73% after TAA-Ts infusion, an improvement as compared with prior therapy.

Overall, the Phase 1 trial of TAA-Ts resulted in safely induced disease stabilization and was associated with antigen spreading and a reduction in circulating tumor-associated antigen DNA levels in patients with relapsed/refractory solid tumors before infusion.

“The T cell immunotherapy regimen resulted in prolonged disease stabilization in patients who previously experienced rapid tumor progression,” said Dr. Meany. “The therapy could prove to be an important component of immunotherapy for patients with solid tumor malignancies,” she added.

Children’s National ranked No. 6 overall and No. 1 for newborn care by U.S. News

Children’s National in Washington, D.C., is the nation’s No. 6 children’s hospital and, for the third year in a row, its neonatology program is No.1 among all children’s hospitals providing newborn intensive care, according to the U.S. News Best Children’s Hospitals annual rankings for 2019-20.

This is also the third year in a row that Children’s National has been in the top 10 of these national rankings. It is the ninth straight year it has ranked in all 10 specialty services, with five specialty service areas ranked among the top 10.

“I’m proud that our rankings continue to cement our standing as among the best children’s hospitals in the nation,” says Kurt Newman, M.D., President and CEO for Children’s National. “In addition to these service lines, today’s recognition honors countless specialists and support staff who provide unparalleled, multidisciplinary patient care. Quality care is a function of every team member performing their role well, so I credit every member of the Children’s National team for this continued high performance.”

The annual rankings recognize the nation’s top 50 pediatric facilities based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.

“The top 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver outstanding care across a range of specialties and deserve to be nationally recognized,” says Ben Harder, chief of health analysis at U.S. News. “According to our analysis, these Honor Roll hospitals provide state-of-the-art medical expertise to children with rare or complex conditions. Their rankings reflect U.S. News’ assessment of their commitment to providing high-quality, compassionate care to young patients and their families day in and day out.”

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

Below are links to the five specialty services that U.S. News ranked in the top 10 nationally:

The other five specialties ranked among the top 50 were cardiology and heart surgery, diabetes and endocrinology, gastroenterology and gastro-intestinal surgery, orthopedics, and urology.

Vittorio Gallo Alpha Omega Alpha Award

Vittorio Gallo, Ph.D., inducted into Alpha Omega Alpha

Vittorio Gallo Alpha Omega Alpha Award

Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National, was inducted into Alpha Omega Alpha (AΩA), a national medical honor society that since 1902 has recognized excellence, leadership and research in the medical profession.

“I think it’s great to receive this recognition. I was very excited and surprised,” Gallo says of being nominated to join the honor society.

“Traditionally AΩA membership is based on professionalism, academic and clinical excellence, research, and community service – all in the name of ‘being worthy to serve the suffering,’ which is what the Greek letters AΩA stand for,” says Panagiotis Kratimenos, M.D., Ph.D., an ΑΩΑ member and attending neonatologist at Children’s National who conducts neuroscience research under Gallo’s mentorship. Dr. Kratimenos nominated his mentor for induction.

“Being his mentee, I thought Gallo was an excellent choice for AΩΑ faculty member,” Dr. Kratimenos says. “He is an outstanding scientist, an excellent mentor and his research is focused on improving the quality of life of children with brain injury and developmental disabilities – so he serves the suffering. He also has mentored numerous physicians over the course of his career.”

Gallo’s formal induction occurred in late May 2019, just prior to the medical school graduation at the George Washington University School of Medicine & Health Sciences (GWSMHS) and was strongly supported by Jeffrey S. Akman, Vice President for Health Affairs and Dean of the university’s medical school.

“I’ve been part of Children’s National and in the medical field for almost 18 years. That’s what I’m passionate about: being able to enhance translational research in a clinical environment,” Gallo says. “In a way, this recognition from the medical field is a perfect match for what I do. As Chief Research Officer at Children’s National, I am charged with continuing to expand our research program in one of the top U.S. children’s hospitals. And, as Associate Dean for Child Health Research at GWSMHS, I enhance research collaboration between the two institutions.”

T cell

Clinical Trial Spotlight: Is more really better? Dose escalation of multi-antigen targeted T cells to illicit a more robust response

T cell

As the promise of immunotherapy in treating patients with cancer becomes more evident, physician researchers at Children’s National are pushing the needle further along. Holly Meany, M.D., is leading a Phase 1 dose-escalation trial to determine the safety and efficacy of administering rapidly generated tumor multi-antigen associated specific cytotoxic T lymphocytes (TAA CTL) to patients who have undergone allogeneic hematopoietic stem cell transplantation (HSCT) or traditional therapy for a high-risk solid tumor due to the presence of refractory, relapsed and/or residual detectable disease.

“In the escalation portion of our trial, we found that the highest dose evaluated did not have unfavorable toxicity in these patients and is our recommended dose,” Dr. Meany said. “Our next step is an expansion of the trial in five distinct disease categories – Wilms tumor, neuroblastoma, rhabdomyosarcoma, adenocarcinoma and esophageal carcinoma – to examine efficacy on a broader level at the recommended dose.”

Dr. Meany and fellow research clinicians at Children’s National will evaluate not only what happens to the patients when given the additional dosage, but also what happens to the cells – How long will they last? Will they remain targeted against the same antigens or will they shift to target other proteins?

This novel trial is currently enrolling patients at Children’s National Health System in Washington, D.C.

Suvankar Majumdar

Spotlight on Suvankar Majumdar, M.D.

Suvankar Majumdar

As a provider with international experience, Suvankar Majumdar, M.D., joined Children’s National in August 2017 as chief of Children’s Division of Hematology within the Center for Cancer and Blood Disorders. Dr. Majumdar is excited to be at Children’s National because of the opportunities for growth, cutting-edge research and continuing education that our diverse population of patients can provide clinicians.

Born in Zambia, in southern Africa, and educated in the United Kingdom, Dr. Majumdar moved to Zimbabwe to study medicine, which he considers the turning point of his career. While in medical school, Dr. Majumdar oversaw and managed the treatment of patients with HIV and other chronic illnesses and determined that blood disorders, particularly sickle cell, was where he wanted to place his focus. Since then, he has served as the Director of the Comprehensive Pediatric Sickle Cell Program as well as Director of the Hemophilia Treatment Center at the University of Mississippi and is a recognized leader in hematology and sickle cell disease. It is this expertise, as well as his dedication to research studies, that have already made him an asset to Children’s National.

Within the Division of Hematology, Children’s providers focus on treating patients with blood disorders, bleeding and clotting disorders, red blood cell disorders (such as sickle cell) and more. Since coming to Children’s National, Dr. Majumdar has experienced a tremendous amount of dedication and enthusiasm from his colleagues. “I’m excited to build on what our faculty has accomplished so far. We’re already well poised to become a national leader in hematology,” he says. “I have no doubt that we will continue to accomplish our goals through collaboration and working toward a common life-saving cause.”

One of his immediate goals for the division is to focus on bringing improved patient care and accessibility in the surrounding Washington area. Additionally, Dr. Majumdar is currently conducting two research studies for sickle cell disease. As one of his studies enters the second phase, he’s focused on seeing the impact of an intravenous citrulline, a nitric oxide booster, on patients with sickle cell disease. Another study has begun to determine if specific genetic mutations that cause prolonged QT, or irregular heartbeats in patients, cause mortality, as sickle cell patients are predisposed to cardiac episodes.

It is Dr. Majumdar’s hope that the hematology team at Children’s National will also continue training the next generation of providers to advance research, education and clinical aspects of the field. To those looking to join the specialty, Dr. Majumdar suggests keeping an open mind when it comes to collaborating with colleagues. “My dad always said to my siblings and I that ‘to break one stick is easy, but to break three sticks is harder’ and really impressed upon us that we’re stronger together,” he says. “By working together, we’re more likely to produce the results that we’re looking for.”

Being located in the nation’s capital, providers at Children’s National are accustomed to seeing a diverse array of patients. For Dr. Majumdar, this presents a unique opportunity. “Meeting and interacting with different patients and families was really appealing when I decided to come to Children’s National. The variety of cases we see in the Division of Hematology can definitely present new challenges, but it’s also more rewarding,” he says.

Working with the pediatric population is also a passion of his. “Children are resilient and tend to bounce back quickly,” Dr. Majumdar says. “As a parent, I try to empathize with treatment concerns and always treat every child as if they were my own. I’m always going to make sure it’s the best level of care possible.”
