A New Era for Human Health Innovation: University of Maryland Breaks Ground for A. James Clark Hall
The University of Maryland’s A. James Clark School of Engineering hosted the ceremonial groundbreaking of the new A. James Clark Hall at the University of Maryland, College Park, on Friday, Nov. 21. The new building will cultivate transformative new engineering and biomedical technologies to accelerate advancements in human health.

Located at the site of the future building in the Paint Branch Parking Lot, adjacent to the Jeong H. Kim Engineering Building, the event brought together honored guests, dignitaries, and representatives of the University of Maryland and University System of Maryland to celebrate the impact Clark Hall will have on the advancement of biomedical research.

“Our researchers are hard at work on biomedical projects that are staggering in their potential impact—a cure for multiple sclerosis, a cancer vaccine, a magnetic pain reduction system and many others,” said University of Maryland President Wallace Loh. “When complete, this new building will give them the space and facilities to finish the job.”

The 184,000-square-foot building will accommodate the Clark School’s rapidly growing programs and foster collaboration among the many disciplines involved with human health innovation, from bioengineering and mechanical engineering to biology and information technology.

“I’m proud that Maryland continues to be a leader in the biotech industry, and A. James Clark Hall will help us continue to build the skilled workforce we need to remain competitive, support groundbreaking advances in the biomedical and engineering fields, and attract additional economic opportunities,” stated Congressman Steny Hoyer (D-Md.). “This world-class facility will not only attract faculty and students, but it will also ensure that the University of Maryland remains at the forefront of engineering and biomedical technologies to advance human health innovation. I look forward to the new opportunities for federal research partnerships and will continue to support significant research advancements at the University of Maryland and throughout our great state.”

Clark Hall will facilitate world-class research and educational programs, offering state-of-the-art laboratories, student project space, and a new home for the Fischell Department of Bioengineering and the Robert E. Fischell Institute for Biomedical Devices. Located within an hour’s drive from many of the nation’s top bioscience research forces, including the National Institutes of Health (NIH), Walter Reed National Military Medical Center, and the University of Maryland School of Medicine in Baltimore, Clark Hall will serve as a central hub for new partnerships for organizations throughout the Maryland and Washington, D.C. region.

“This new start-of-the-art facility for bioengineering research and education will attract exceptional faculty and students to Maryland, support leading edge research and education, and benefit the state of Maryland’s innovation ecosystem through the creation of new companies and new jobs,” said University System of Maryland Chancellor William E. Kirwan.

While the vision, design, and development of Clark Hall brought together the minds of University of Maryland and Clark School administrators, faculty, and staff, as well as a team of talented architects and builders, the plans could not be executed without the generosity of two benefactors – A. James Clark (B.S. ’50) and Dr. Robert E. Fischell (M.S. ’53, Honorary Sc.D. ’95).

Clark’s steadfast commitment to undergraduate education moved him to endow a fund for undergraduate scholarships in 1994, and in 2005, a new A. James Clark Scholarship Fund to provide financial support to undergraduate engineering students based on merit, need, and diversity. In recognition of Clark’s philanthropic leadership, the University of Maryland School of Engineering was named the A. James Clark School of Engineering. Inspired by his strong interest in the promise of biosciences and biotechnology, Clark made a generous gift to support the design and construction of A. James Clark Hall, which will be the 27th structure built by Clark Construction on the University of Maryland campus.

“Mr. Clark’s contribution to this new building and the University of Maryland is not only a symbol of commitment to his alma mater, but a symbol of his vision for the future of human health,” said Darryll Pines, Clark School Dean and Farvardin Professor.

Fischell is the inventor behind major medical breakthroughs, including highly flexible, drug-eluding coronary stents, the first implantable insulin pump, and a magnetic pulse device for treating human pain ranging from migraine headaches to backaches. His latest inventions include the first rechargeable pacemaker for cardiac patients, an implantable device that warns a patient and medical personnel of a heart attack at the very first sign of its start, and a neurostimulator implanted in the skull that can detect abnormal electrical activity in the brain and correct it before a seizure occurs.

In 2005, Fischell and his family helped to establish the Fischell Department of Bioengineering and the future Robert E. Fischell Institute for Biomedical Devices at the University of Maryland, and, most recently, Fischell committed a generous gift toward the establishment of A. James Clark Hall.

“Dr. Fischell’s commitment to the commercialization of health innovations has made an enormous impact on society, and the Fischell Institute for Biomedical Devices will help our students and faculty to take part in the improvement of human health worldwide,” said William Bentley, the Robert E. Fischell Distinguished Professor of Engineering and Chair of the Fischell Department of Bioengineering.

Slated to open in 2017, Clark Hall was designed by a team of architects at Ballinger and will be developed by Clark Construction Group.

UMD Researchers Explore New Avenues in Treatment of Lysosomal Storage Diseases

Lysosomal storage diseases (LSDs) are rare inherited metabolic disorders that result from defects in lysosomal function, triggered when a particular enzyme exists in too small an amount or is missing altogether. When this happens, excess products destined for breakdown and recycling instead accumulate in the cell. As a result, these genetic defects impair lysosomal degradation, and this impairment often results in fatal cellular and tissue dysfunctions, such as those illustrated in LSDs.

Although the incidence of LSDs is still relatively low – about 1:2000 live births – the financial burden to families and the health system is overwhelming. The cost of current therapies averages $150,000+/per patient-year and yet, such therapies are mostly suboptimal in alleviating these chronic conditions.

While LSDs account for approximately 50 fatal conditions, they are one of the best examples of genetic diseases for which treatment has become clinically available, according to Silvia Muro, Associate Professor with the Fischell Department of Bioengineering and the Institute for Bioscience and Biotechnology Research at the University of Maryland.

One such example of available treatment is that of enzyme replacement therapies (ERTs) by infusion of recombinant enzymes.

Recombinant enzymes are administered via frequent systemic infusions – approximately every two weeks – and require patients to travel to reference centers and endure repeat hospitalizations. This treatment therefore increases cost, risk, and burden to patients.

Additionally, after one decade of its clinical implementation, the success of ERTs by infusion of recombinant enzymes is restricted to few diseases that affect only visceral organs – liver, spleen and kidneys – since injected ERTs access these organs via natural mechanisms of blood clearance.

“This strategy is not practical for most other diseases due to suboptimal enzyme accumulation in other organs, poor transport into tissues across blood-to-tissue barriers, and generation of antibodies against the injected enzymes,” Muro said.

As such, Muro and members of her research team are working toward achieving encapsulatation of recombinant enzymes in protective nanocarriers that are targeted to cell surface markers involved in transport, such as the intercellular adhesion molecule involved in natural blood-to-tissue passage of white blood cells. Their published results using animal models show that enzyme delivery is markedly enhanced throughout the body using this strategy, which they hope will help lessen the burdens patients face and improve the effectiveness of treatment for LSDs. Muro’s patent application on this technology was issued this past November.

In addition to causing cellular and tissue dysfunctions, lysosomal storage appears to alter endocytosis, a cellular process where cells engulf in membranous compartments and subsequently internalize extracellular materials and membrane components.

Many basic functions in the body depend on endocytosis, including uptake of nutrients and signaling molecules by cells, defense against pathogens and toxic substances, and recycling of components located at the interface between the cell and extracellular environment. Endocytosis is also commonly used to achieve intercellular transport of therapeutics, Muro said.

“Endocytosed drug carriers usually traffic to lysosomes, where drugs are released and carriers are expected to be degraded in order to avoid side effects,” she said. “Therefore, lysosomes are key to drug delivery. Lysosomes are also key to cell function including catabolism of macromolecules, recycling of membrane components, and autophagy.”

Whether accumulation of drug carriers – or their component – within lysosomes in cells causes similar disruptions to those observed in lysosomal diseases is yet unknown, Muro said. But, emphasized by Muro’s studies on lysosomal diseases, the field of drug delivery recognizes that this is an important question in understanding – and minimizing – potential side effects of drug delivery systems.

“If we understand for how long carriers or carrier-derived components accumulate in lysosomal compartments in cells and what their effects are regarding lysosomal functioning, we could optimize the design of materials used for fabrication of drug carriers, their clearance within cells, and their dosage and administration regime, while reducing their size effects,” Muro said.
