About Us: SMA Foundation Leadership

Loren A. Eng | President

Loren Eng is the President of the Spinal Muscular Atrophy Foundation, a nonprofit organization which develops treatments for SMA, the leading genetic cause of death in young children. Since its inception, the Foundation has funded over $150 million in research and therapeutics development. The Foundation collaborates with leading academic medical centers, the federal government (DoD, NIH, CDC, FDA), and nearly every pharmaceutical company in the world including: Roche, Biogen, and Novartis. When the SMA Foundation was established in 2003, there were no treatments for SMA. Due to the Foundation’s investments and drug discovery efforts, today there are three FDA-approved drugs.  There are several others in advanced clinical development and in preclinical development. One of our first investments resulted in Spinraza which was the first drug approved for SMA. In 2017, Spinraza won the Prix Galien Award for Best Biotechnology Product of the year. In 2019, Dr. Frank Bennett (our collaborator at Ionis Pharmaceuticals) and Dr. Adrian Krainer (our collaborator at CSHL) received the Breakthrough Prize in Life Sciences (for the development of Spinraza).  The SMA Foundation funded the basic science research and clinical trials network; and we worked on the full scope of the therapeutics development which led to the drug Spinraza.

Ms. Eng and the work of the Foundation have been featured in national media including ABC NewsBloomberg MarketsForbesFox NewsThe New York TimesNightlineParents Magazine, and the Today Show. Ms. Eng has spoken before Congress on numerous occasions regarding: SMA, NIH funding and biomedical research. She and the SMA Foundation have been recognized with: the Child Neurology Foundation Award, the Giblin Foundation Award and the Columbia Crown Award.

The accomplishments of the SMA Foundation were highlighted in a 2017 MIT Sloan School of Management case study that focused on venture philanthropy. The strategic decisions of the SMA Foundation that culminated in the discovery of new treatments for a devastating childhood motor neuron disease are a focus of an upcoming Harvard Business School case study. The work of the SMA Foundation is also featured in "Breakthrough, The Quest for Life-Changing Medicines," a book by Pfizer CMO William Pao which follows eight devastating diseases and the people who drove the development of revolutionary treatments. Harvard Medical School is also developing a course solely based on SMA and the SMA Foundation. This course will be open to students outside of HMS including undergraduates and business school students.

Prior to establishing the SMA Foundation, Ms. Eng worked in investment banking, merchant banking and business development for media.  Ms. Eng received a BA with honors from Wellesley College, and an MBA as well as an MA in Education from Stanford University.

Lee Rubin, PhD | Research Strategist

Lee Rubin is a Principal Investigator Professor at Harvard University’s Department of Stem Cell and Regenerative Biology. Dr. Rubin has a broad experience in both academia and industry, particularly in the realms of cell-based assays and drug discovery. Prior to coming to Harvard, he was Chief Scientific Officer of Curis, Inc., a Cambridge-based biotechnology company, where his group identified the first small molecule regulators of the hedgehog signaling pathway. One of these antagonists was developed by Genentech and is now (as Erivedge) approved as the first oral treatment for metastatic basal cell carcinoma. At Harvard, much of his work is focused on finding key molecular mediators of different neurodegenerative diseases and on searching for effective preclinical therapeutic candidates. His research takes advantage of his group’s ability to produce large numbers of patient-derived induced pluripotent stem cell lines and of effective means of deriving differentiated neurons from them. They have set up an array of techniques that allow them to identify early cellular and physiological changes in neurons as they become diseased. For example, they have identified new targets for the treatment of the motor neuron disorders Spinal Muscular Atrophy and Amyotrophic Lateral Sclerosis. Recently, his group discovered that a circulating protein, GDF11, has the ability to reverse some of the changes in the CNS associated with aging. They are actively exploring the therapeutic implications of these observations as well. Finally, his group works closely with faculty at the Broad Institute to apply various approaches to understand and treat neuropsychiatric disease. Dr. Rubin received his PhD in neuroscience from the Rockefeller University and had postdoctoral training, also in Neuroscience, at Harvard Medical School and Stanford University School of Medicine.
