PPMD’s Scientific Advisory Committee (SAC)
Parent Project Muscular Dystrophy’s research strategy is supported by our Scientific Advisory Committee (SAC) made up of clinicians, researchers, parents, and other experts in Duchenne research and care. These individuals are dedicated to PPMD and its mission and volunteer many hours throughout the year to oversee, and provide stewardship to, PPMD’s research program. The SAC members serve as advisors to PPMD’s scientific and research priorities, goals and programs. The committee, chaired by PPMD Senior Scientific Advisor Dr. Lee Sweeney, meets as needed to review grants and discuss research priorities and strategies.
The role of the SAC is threefold:
- Develop and recommend to PPMD staff and board both short- and long-term research strategies, goals, and programs and help guide PPMD’s research strategy.
- Advise the PPMD staff and board in the research-related aspects of other PPMD programs, such as clinical trial development tool initiatives and PPMD’s advocacy and public policy agenda.
- Assist in the development of the PPMD research strategy, review research proposals, and offer advice on issues relating to the PPMD research strategy.
Jerry R. Mendell, M.D., a longtime SAC member says:
“It is a privilege to serve on the PPMD Scientific Advisory with the range of expertise represented by its members. The Committee has exceptional depth, with representation throughout a range of disciplines, from molecular biochemistry to clinical trials, all linked by a common mission – helping boys with Duchenne muscular dystrophy. I think this will be an incredibly productive experience for both committee members and for PPMD.”

H. Lee Sweeney, PhD
Senior Scientific Advisor and Committee Chair
Dr. Sweeney’s basic research interests are focused on molecular motors of the myosin superfamily. Notable among his accomplishments on molecular motors was the first visualization of structural rearrangement of the myosin lever arm, a detailed analysis of how processive myosins are engineered, a demonstration of the structural changes induced by actin-binding and nucleotide release, and the discovery and molecular dissection of the only known reverse-direction myosin. Much of Dr. Sweeney’s research program is translational in focus, and has produced highly cited research on inherited forms of cardiovascular disease, and on the skeletal and cardiac aspects of muscular dystrophy. Dr. Sweeney was elected as a Fellow of the American Heart Association in 2001. He has been Director of a Paul Wellstone Muscular Dystrophy Cooperative Center since 2005, which is now the University of Florida (UF) Wellstone Muscular Dystrophy Cooperative Center. Dr. Sweeney is actively developing therapeutics for rare diseases that include both small molecule and gene therapy approaches. He serves as a consultant to a number of industry therapeutic development efforts for Duchenne muscular dystrophy and Spinal Muscular Atrophy.
Dr. Sweeney is well known in the popular press for his gene-therapy approaches to permanently block the loss of age-related muscle size and strength in mice. The technique suggests that therapies for humans could reverse the feebleness associated with old age or slow the muscle-wasting effects of muscular dystrophies. Based on the enhancement this creates in healthy young animals, Dr. Sweeney has been widely sought as an expert commentator on the potential for gene “doping” in sports, as well as on the bioethical issues surrounding genetic enhancement. In 2004, this work led to Dr. Sweeney being among those chosen by Esquire Magazine as the “Best and Brightest” in America.
Dr. Sweeney is also heavily involved in small molecule therapy development for muscle disease. In 2007, he and his collaborators at PTC Therapeutics (a small NJ biotech company) published the development of a compound (PTC 124 or ataluren) that allows read-through of nonsense mutations (premature stop codons) in a variety of genetic disease models. The drug is in clinical trials for Duchenne muscular dystrophy and Cystic Fibrosis. For this work, Dr. Sweeney was awarded a Hamdan Award for Medical Research Excellence from Sheikh Hamdan of Dubai in 2008. On May 23, 2014, ataluren was granted conditional European approval for the treatment of Duchenne, making it the first approved drug for this disease.

Kathryn R. Wagner, MD, PhD
Dr. Wagner is the Director of the Center for Genetic Muscle Disorders at the Kennedy Krieger Institute and Associate Professor of Neurology and Neuroscience at the Johns Hopkins School of Medicine. She treats patients with muscular dystrophies in a multidisciplinary clinic, addressing the multiple medical and social issues affecting these individuals and families. Dr. Wagner conducts clinical trials in muscular dystrophy including the first clinical trial of nonsense suppression in Duchenne and the first clinical trial of myostatin inhibition in adult muscular dystrophy. Dr. Wagner’s laboratory focuses on developing methods to promote muscle regeneration. A major emphasis of her laboratory has been on modulating myostatin, an endogenous regulator of muscle. Dr. Wagner’s laboratory has shown that inhibition of myostatin stimulates muscle stem cells, improving muscle regeneration while reducing fibrosis in animal models of muscular dystrophy. Current efforts include collaborations with industry to combine stem cell and pharmacological therapies for enhanced regeneration.
