Gene therapy is the introduction of genetic material into cells to replace missing or defective genes. If a gene doesn’t function properly, the introduction of a normal copy of a gene may be able to treat or prevent disease. It is a technique that has the potential to deliver long-term and potentially curative benefits to patients with genetic disorders.

Beacon Therapeutics
Beacon is a leading ophthalmic gene therapy company with a purpose to restore and improve the vision of patients with a range of prevalent and rare retinal diseases that result in blindness. Syncona launched Beacon in June 2023, having invested £75 million of the £96 million Series A financing. As part of this Series A financing, AGTC was combined with new Syncona company, Beacon Therapeutics, merging AGTC’s lead clinical gene therapy asset with two exciting pre-clinical programmes, including one from the University of Oxford.

As we seek to build a diversified portfolio of 20-25 companies, some companies may not succeed and we may receive attractive offers for our companies from third parties.

Gyroscope Therapeutics
Syncona founded Gyroscope in 2016, to explore the convergence of advancements made in the understanding of the complement system’s impact on eye disease, the genetic basis of dry age-related macular degeneration (AMD), and gene therapy as a mode of sustained treatment delivery. Gyroscope’s gene therapy seeks to treat dry AMD by safely and effectively delivering a functioning gene to the eye using Adeno-Associated Virus (AAV) technology.
Blue Earth
Blue Earth Diagnostics was founded to develop and commercialise molecular imaging agents, addressing areas of high unmet medical need.
Nightstar
Nightstar was a leading clinical-stage gene therapy company focused on developing and commercialising novel one-time treatments for patients suffering from rare inherited retinal diseases that would otherwise progress to blindness.

Neogene Therapeutics
Neogene was founded in 2018, based on the work of Dr Ton Schumacher, a leading cancer immunologist, and Dr Carsten Linnemann, who was previously associate director of next generation T cell therapy at Kite Pharma. In 2020 Syncona co-led the company’s $110 million Series A financing round, committing $19 million alongside EcoR1 Capital, Jeito Capital, Polaris Partners, Pontifax, Vida Ventures, TPG and Two River.
