Katherine A. High is an American doctor-scientist who is an emeritus professor at the Perelman School of Medicine at the University of Pennsylvania. She was the co-founder, president, and chief scientific officer of Spark Therapeutics and currently serves as President of Therapeutics at AskBio. [1] Her career has focused on pioneering work in the area of gene therapy, with many accomplishments in basic, translational, and clinical investigation in gene therapy.
High received an A.B. in chemistry at Harvard University in 1972. [2] [3] She started her medical training at the University of North Carolina (UNC) School of Medicine, during which she took a leave of absence to work in a chemistry research lab at UNC. [4] After returning and completing her medical degree in 1978, High continued with a residency in internal medicine. [5] She then became a hematology fellow at Yale University under the supervision of Edward J Benz Jr, during which she worked on the molecular genetics of globin genes and oncogenes. [6] [5]
High has been recognized for her distinguished contributions to the field of gene therapy, having designed, sponsored, and conducted the first clinical trial of an adeno-associated viral vector (AAV) gene therapy injected into the skeletal muscle (1999), [7] the first trial of AAV gene therapy introduced into the liver (2001), [8] and the first trial in the US of an AAV gene therapy injected into the subretinal space (2007). [9]
High was a faculty member at the University of North Carolina - Chapel Hill for seven years, [10] [5] where she started her career by developing a canine model of the study of gene therapy for hemophilia by cloning the canine Factor IX gene. [11] She also identified the mutations responsible for several Factor VII and Factor X-deficient blood clotting disorders. [12] High moved to the University of Pennsylvania and Children's Hospital of Philadelphia, where she began pioneering gene therapies for blood disorders. [13] During her career at the University of Pennsylvania, High expanded her research into gene therapy solutions for hereditary blindness together with Dr. Jean Bennett. [14]
She was the director of the Center for Cellular and Molecular Therapeutics, and as of 2001 [update] head of hematology research, [1] at the Children's Hospital of Philadelphia and an investigator of the Howard Hughes Medical Institute. [15] [16] High is an elected member of the National Academy of Medicine of the American Academy of Arts and Sciences, and of the Faculty of Pharmaceutical Medicine of the Royal College of Physicians (London).
Along with Jean Bennett, in 2018, she was awarded Sanford Health's $1 million Lorraine Cross Award for innovation in medicine and science.
From 2014 to 2020, High served as the co-founder, President, Chief Scientific Officer/Head of R&D and a Member of the Board of Directors of Spark Therapeutics, a fully integrated, commercial gene therapy company in Philadelphia. While at Spark Therapeutics, Dr. High led the team that obtained the first FDA approval of an AAV therapeutic (Luxturna®) in December 2017 and led the team that obtained Breakthrough Therapy designations for three product candidates, SPK-RPE65 (Luxturna®), SPK-9001 for hemophilia B, and for SPK-8011 for hemophilia A.
In February 2020, High stepped down from her position at Spark Therapeutics as the company prepared to be absorbed by Swiss pharma Roche. [17]
In January 2021, High joined Asklepios Biopharmaceutical, or AskBio, a clinical-stage adeno-associated virus (AAV) gene therapy company and wholly owned subsidiary of Bayer AG, as the company's new President of Therapeutics and as a board member for AskBio. In this role, Dr. High is responsible for the development of the company's for driving the strategic direction and execution of the company's preclinical and clinical programs.
In April 2021, she was elected a member of the U. S. National Academy of Sciences. [18]
She is married to George Steele, a nutritionist who was on the faculty of the University of Pennsylvania School of Medicine. [19] [20] She has three children, one of whom is actress Sarah Steele. [21] [22]
Gene therapy is a medical technology that aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells.
Haemophilia, or hemophilia, is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding. This results in people bleeding for a longer time after an injury, easy bruising, and an increased risk of bleeding inside joints or the brain. Those with a mild case of the disease may have symptoms only after an accident or during surgery. Bleeding into a joint can result in permanent damage while bleeding in the brain can result in long term headaches, seizures, or a decreased level of consciousness.
Haemophilia B, also spelled hemophilia B, is a blood clotting disorder causing easy bruising and bleeding due to an inherited mutation of the gene for factor IX, and resulting in a deficiency of factor IX. It is less common than factor VIII deficiency.
Coagulation factor VII is one of the proteins that causes blood to clot in the coagulation cascade, and in humans is coded for by the gene F7. It is an enzyme of the serine protease class. Once bound to tissue factor released from damaged tissues, it is converted to factor VIIa, which in turn activates factor IX and factor X.
Adeno-associated viruses (AAV) are small viruses that infect humans and some other primate species. They belong to the genus Dependoparvovirus, which in turn belongs to the family Parvoviridae. They are small replication-defective, nonenveloped viruses and have linear single-stranded DNA (ssDNA) genome of approximately 4.8 kilobases (kb).
Retinal gene therapy holds a promise in treating different forms of non-inherited and inherited blindness.
Alipogene tiparvovec, sold under the brand name Glybera, is a gene therapy treatment designed to reverse lipoprotein lipase deficiency (LPLD), a rare recessive disorder, due to mutations in LPL, which can cause severe pancreatitis. It was recommended for approval by the European Medicines Agency in July 2012 and approved by the European Commission in November of the same year. It was the first marketing authorisation for a gene therapy treatment in either Europe or the United States.
Self-complementary adeno-associated virus (scAAV) is a viral vector engineered from the naturally occurring adeno-associated virus (AAV) to be used as a tool for gene therapy. Use of recombinant AAV (rAAV) has been successful in clinical trials addressing a variety of diseases. This lab-made progeny of rAAV is termed "self-complementary" because the coding region has been designed to form an intra-molecular double-stranded DNA template. A rate-limiting step for the standard AAV genome involves the second-strand synthesis since the typical AAV genome is a single-stranded DNA template. However, this is not the case for scAAV genomes. Upon infection, rather than waiting for cell mediated synthesis of the second strand, the two complementary halves of scAAV will associate to form one double stranded DNA (dsDNA) unit that is ready for immediate replication and transcription. The caveat of this construct is that instead of the full coding capacity found in rAAV (4.7–6kb) scAAV can only hold about half of that amount (≈2.4kb).

Mavis Agbandje-McKenna was a Nigerian-born British medical biophysicist, structural virologist, and a professor of structural biology, as well as the director of the Center for Structural Biology at the University of Florida in Gainesville, Florida. Agbandje-McKenna studied parvovirus structures using X-ray crystallography and cryogenic electron microscopy and did much of the initial work to elucidate the basic structure and function of adeno-associated viruses (AAVs). Her viral characterization and elucidation of antibody binding sites on AAV capsids has led to the development of viral capsid development and gene therapy approaches that evade immune detection and can be used to treat human diseases such as muscular dystrophies. Agbandje-McKenna was recognized with the 2020 American Society of Gene and Cell Therapy Outstanding Achievement Award for her contributions to the field. She died in 2021 from amyotrophic lateral sclerosis.
