Overview
Novartis Gene Therapies is a biotechnology business focused on developing and commercializing gene therapies for rare neurological genetic disorders. The organization originated in Dallas, Texas, in 2012 under the name AveXis. It was established by John Carbona after the reorganization of BioLife Cell Bank, a company founded by David Genecov and John Harkey. From its beginning, AveXis was built around a gene-therapy approach for spinal muscular atrophy (SMA), a severe inherited neuromuscular disease caused by insufficient survival motor neuron protein and characterized by progressive loss of motor function. A central part of the company’s early development was its relationship with Nationwide Children's Hospital and the laboratory of researcher Brian Kaspar. In October 2013, AveXis licensed work from the hospital’s laboratory concerning a method for treating SMA with gene therapy. The arrangement was notable because Nationwide Children's Hospital received not only upfront and milestone payments but also an equity interest in AveXis. Brian Kaspar became a paid consultant under the licensing relationship. This research formed the scientific foundation for the company’s lead product, onasemnogene abeparvovec, later marketed as Zolgensma. Novartis acquired AveXis in 2018 for approximately US$8.7 billion, bringing the company and its gene-therapy platform into the Novartis group. The acquisition gave Novartis a specialized rare-disease and advanced-therapy operation and positioned the business to bring its SMA treatment through regulatory review and commercialization. In 2019, onasemnogene abeparvovec received approval in the United States. The product became notable both for its one-time gene-therapy treatment model and for its US list price of US$2.125 million per injection, which made it the most expensive medicine in the world at the time. The product subsequently expanded its regulatory presence. In May 2020, it received conditional approval in the European Union for patients with SMA and a clinical diagnosis of SMA Type 1, as well as SMA patients with up to three copies of the SMN2 gene. In September 2020, Novartis renamed AveXis as Novartis Gene Therapies. The name change aligned the business more directly with its parent company while preserving its focus on gene-based treatments for serious neurological conditions. The organization’s development was also accompanied by regulatory controversy. Shortly after Zolgensma’s approval, the US Food and Drug Administration accused AveXis of data manipulation in a regulatory submission and in other submissions. Following an investigation, allegations centered on Brian Kaspar and his brother Allan Kaspar, who had served as a senior vice president of research and development. They were alleged to have ordered and attempted to conceal the manipulation, and both were subsequently removed from the company. These events became an important part of the company’s corporate and regulatory history. Novartis Gene Therapies remains associated primarily with Zolgensma and with Novartis’s broader effort to develop therapies for rare genetic and neurological diseases. Publicly available reference material identifies the company’s origin, acquisition, rebranding, lead product, and regulatory controversy, but does not provide a complete current executive roster or a comprehensive list of additional commercial products.
History
Novartis Gene Therapies began as AveXis, a biotechnology company founded in Dallas, Texas, in 2012 by John Carbona. Carbona formed the business after reorganizing BioLife Cell Bank, which had been founded by David Genecov and John Harkey. AveXis was created with a focused scientific and commercial objective: to develop gene-therapy treatments for rare neurological genetic diseases, especially spinal muscular atrophy. The company’s principal technology originated in research conducted at Nationwide Children's Hospital in the laboratory of Brian Kaspar. In October 2013, AveXis licensed this work, which concerned a gene-therapy method for SMA. The licensing arrangement included upfront and milestone payments and gave Nationwide Children's Hospital an equity position in AveXis, an unusual feature for a hospital research partnership at that time. Brian Kaspar also became a paid consultant under the agreement. The licensed research became the basis for the company’s lead therapy, onasemnogene abeparvovec. Novartis purchased AveXis in 2018 for approximately US$8.7 billion. The transaction incorporated AveXis into Novartis and strengthened the larger company’s presence in rare diseases and advanced gene-based medicines. In 2019, onasemnogene abeparvovec received approval in the United States under the brand name Zolgensma. It was developed as a one-time treatment for eligible patients with spinal muscular atrophy. Its US list price of US$2.125 million per injection drew extensive attention and made it the most expensive drug in the world at the time. In May 2020, Zolgensma received conditional approval in the European Union for defined SMA populations, including patients with a clinical diagnosis of SMA Type 1 and patients with up to three copies of the SMN2 gene. Later that year, in September 2020, Novartis renamed AveXis as Novartis Gene Therapies. The new name emphasized the business’s role within Novartis and its focus on gene-therapy development. The company also faced a significant regulatory controversy after the approval of Zolgensma. The US Food and Drug Administration accused AveXis of data manipulation in a regulatory submission and other submissions. An investigation alleged that Brian Kaspar and his brother Allan Kaspar, who had been a senior vice president of research and development, ordered and attempted to conceal the manipulation. Both were subsequently removed from the company. The episode affected the organization’s regulatory history and remains a major consideration in accounts of AveXis and Novartis Gene Therapies. The available reference material identifies Novartis Gene Therapies principally with Zolgensma and its SMA-focused gene-therapy platform. It does not establish a complete current leadership list, additional marketed products, or a separate public-company listing for the business.
