International Harrington Prize Jointly Awarded to Drs. Jean Bennett and Albert Maguire

International Harrington Prize Winners 2023
Jean Bennett, MD, PhD, the F.M. Kirby Emeritus Professor of Ophthalmology and Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania, and Albert M. Maguire, MD, the F.M. Kirby Professor of Molecular Ophthalmology at the Perelman School of Medicine at the University of Pennsylvania.

The tenth annual Harrington Prize for Innovation in Medicine has been jointly awarded to Jean Bennett, MD, PhD, the F.M. Kirby Emeritus Professor of Ophthalmology and Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania, and Albert M. Maguire, MD, the F.M. Kirby Professor of Molecular Ophthalmology at the Perelman School of Medicine at the University of Pennsylvania. The award recognizes this team’s groundbreaking translational research to restore sight in inherited genetic diseases.

The Harrington Prize for Innovation in Medicine, established in 2014 by the Harrington Discovery Institute at University Hospitals and the American Society for Clinical Investigation (ASCI), honors physician-scientists who have moved science forward with achievements notable for innovation, creativity, and potential for clinical application.

Dr. Jean Bennett and Dr. Albert Maguire are pioneers in retinal gene therapies, conducting their early work at a time when there were few guideposts. Working collaboratively for the past 30 years, they are widely recognized for persistence and dedication that has led to a first fully approved breakthrough treatment for blindness.

Drs. Bennet and Maguire’s striking results in a dog model of Leber’s congenital amaurosis (LCA), a rare genetic cause of blindness, provided support for human clinical trials, which reversed blindness in children and resulted in FDA approval of gene therapy to the eye.

Building on their work in LCA, the Bennett-Maguire team initiated a clinical trial for a second inherited retinal degeneration, Choroideremia, a disease leading to complete blindness in affected men by middle age. In doing so, they opened a path from laboratory to clinic in additional blinding diseases.

“The path from proof-of-concept to delivering a safe and effective treatment to patients is one that few physician-scientists are able to experience. Drs. Bennett and Maguire have achieved many ‘firsts’ through their groundbreaking work and have opened the gates for many new treatments to follow,” said Sohail F. Tavazoie, MD, PhD, Leon Hess Professor, The Rockefeller University and 2022-2023 President of the ASCI.

“The translational work of Drs. Bennett and Maguire has impacted the standard of care for patients living with congenital blindness and offered new hope where none existed. Their extraordinary achievements are precisely what the Harrington Prize seeks to recognize,” said Jonathan S. Stamler, MD, President, Harrington Discovery Institute, Robert S. and Sylvia K. Reitman Family Foundation Distinguished Professor of Cardiovascular Innovation and Professor of Medicine and of Biochemistry at University Hospitals and Case Western Reserve University.

A committee composed of members of the ASCI Council and the Harrington Discovery Institute Scientific Advisory Board reviewed nominations from leading academic medical centers globally before selecting the 2023 Harrington Prize recipients.

In addition to sharing the Prize’s $20,000 honorarium, co-recipients Dr. Bennett and Dr. Maguire will deliver the Harrington Prize Lecture at the 2023 AAP/ASCI/APSA Joint Meeting on April 21, will be featured speakers at the 2023 Harrington Scientific Symposium May 24-25, and will co-publish an essay in the Journal of Clinical Investigation.

The American Society for Clinical Investigation

Founded in 1908, the American Society for Clinical Investigation is one of the oldest and most esteemed nonprofit honor societies of physician-scientists. Membership is by election only, and only researchers who are 50 years of age or younger are eligible for nomination to the Society. Therefore, membership in the ASCI is a recognition of a researcher’s significant contributions, at a relatively young age, to the understanding of human disease. The Society counts among its ranks more than 3,000 members, many of whom are leaders in academic medicine and industry. Many members have been recognized by election to the U.S. National Academy of Sciences and the U.S. National Academy of Medicine. The ASCI is also proud to have among its membership winners of the Nobel Prize and the Lasker Award. The ASCI convenes an annual meeting with the Association of American Physicians, and the Society self-publishes the prestigious Journal of Clinical Investigation (founded 1924), and JCI Insight (founded 2016).

Harrington Discovery Institute

The Harrington Discovery Institute at University Hospitals in Cleveland, OH – part of The Harrington Project for Discovery & Development – aims to advance medicine and society by enabling our nation’s most inventive scientists to turn their discoveries into medicines that improve human health. The institute was created in 2012 with a $50 million founding gift from the Harrington family and instantiates the commitment they share with University Hospitals to a Vision for a ‘Better World’.
