Mr. Kelly has over 25 years of experience in the field of gene therapy, serving in a range of scientific, technical, and operational roles. Mr. Kelly has had oversight of early and late stage CMC for AAV, lentiviral, retroviral, and adenoviral vectors and associated ex-vivo cell therapy programs in ophthalmology, CNS, neuromuscular and oncology indications.

Prior to joining Atsena, Mr. Kelly was VP of Process Development at Avrobio, where he was responsible for the development of CMC for the companies ex-vivo cell therapies. Prior to that he was responsible for CMC oversight for Biogen’s gene therapy portfolio, including business development activities in support of gene therapy transactions. Mr. Kelly held various senior roles in gene therapy CMC at Sanofi-Genzyme, Cell Genesys and Somatix Therapy Corporation. Mr. Kelly also serves as the chair for viral vector sector of the Standards Coordinating Body for Gene, Cell and Regenerative medicine and is a member of its board of directors.

Mr. Kelly holds B.Sc. and M.Sc. degrees from the National University of Ireland, Galway.

Sanford Boye, MSc

Mr. Sanford Boye is an Associate Scientist of Pediatrics and Associate Director of the Powell Gene Therapy Center at the University of Florida. His research on AAV and ocular gene therapy spans 20 years and over 100 publications. His work has focused primarily on the design and utilization of recombinant adeno-associated virus (AAV) vectors for gene transfer to the eye and the evaluation of AAV based gene therapies in models of retinal disease. He has designed AAV vectors that have been used to establish proof of concept for the treatment of autosomal recessive retinitis pigmentosa, X-linked retinitis pigmentosa, achromatopsia, Bardet-Biedl syndrome, Usher syndrome and multiple forms of Leber congenital amaurosis (LCA). Several of these gene therapies have gone on to be clinically applied, including a gene therapy for LCA due to mutation in RPE65 and what would ultimately become Luxturna, the first gene therapy approved by the FDA. Recently, his work has focused on modifications of the AAV capsid to improve vector performance and safety. Currently, he splits his time between working with Dr. Shannon Boye on both basic science research and translational programs and directing the Vector Core within the Powell Gene Therapy Center.

She graduated from Harvard University with a magna cum laude in neuroscience, went to medical school at the University of Florida and completed her vitreoretinal surgical fellowship at the University of Iowa. After her vitreoretinal surgical fellowship, she was awarded a five-year Career Development Award from the Foundation Fighting Blindness, which launched her career as a clinical-scientist and inherited retinal disease specialist, and funded research focusing on optimizing adeno-associated virus (AAV) genetic therapy for the treatment of achromatopsia.

Dr. Kay is a member of the American Academy of Ophthalmology and has been inducted into Macula Society and Retina Society, and has published over 20 either first or senior author articles in peer-reviewed ophthalmic journals, authored textbook chapters and serves as an editor for multiple ophthalmology and retinal journals. She has developed a large inherited retinal disease patient population in her clinic, with over 1,000 patients in her clinical database and with 800 of these patients genotyped.

She is currently a principal investigator in 12 inherited retinal disease clinical trials, including surgical gene therapy trials, and has performed multiple subretinal injections within ocular gene therapy clinical trials. Her combined interests in management of IRDs, IRD clinical trials, and optimization of vitreoretinal surgical delivery techniques allows a unique perspective in the field of ocular gene therapy.

Swan Endowed Professorship and is the Chief of the Ophthalmic Genetics Division at the Casey Eye Institute. Dr. Pennesi attended the University of Pennsylvania, where he graduated summa cum laude with a bachelor’s degree in biomedical engineering and was awarded the Herman P. Schwann award in bioengineering for exemplary scholarship. Dr. Pennesi’s interest in degenerative retinal disorders began shortly after his first year in college when he spent a summer working at the Retina Foundation of the Southwest, where he worked under the supervision of Dr. David Birch seeing patients with inherited retinal degenerations, such as retinitis pigmentosa.

Dr. Pennesi pursued a combined MD/PhD at Baylor College of Medicine in Houston, Texas. He received numerous awards while in graduate school, including the John J. Trentin Award for earning the highest GPA in his class and the BRASS scholarship for playing an active role in community service. This was followed by a residency in Ophthalmology at University of California, San Francisco, where he was awarded the Hogan-Garcia Award for having the best resident research project. In 2011 Dr. Pennesi received the ARVO/Alcon Early Career Clinician-Scientist Research Award. He is also the recipient of a Foundation Fighting Blindness (FFB) career development award, a Research to Prevent Blindness career development award and an FFB enhanced career development award. He was awarded the Alcon Young Investigator Award in 2014 and a Residency Teaching award in 2015. He has also been elected into both the Macula Society and Retina Society.

Dr. Pennesi is a clinician scientist with a passion for developing novel therapeutic regimens for inherited retinal diseases. He has helped propel the Casey Eye Institute into a leader in novel therapies for inherited retinal dystrophies. He is the PI or Co-PI on numerous clinical trials, including gene augmentation therapy for RPE65-related retinopathy, ABCA4-related retinopathy, Type IB Usher syndrome, CNGA3 and CNGB3-related achromatopsia, X-linked retinoschisis, X-linked retinitis pigmentosa and choroideremia.
