UCL RPE65 Gene Therapy Trial Shows Benefit in People with Leber Congenital Amaurosis Type 2 for up to Three Years After Treatment

Tue, 05 May 2015 14:44:39 +0000

We are delighted to be able to announce that yesterday, Monday 4th May, the long-term results of our RPE65 gene therapy trial for Leber Congenital Amaurosis Type 2 (LCA2) were published in the prestigious New England Journal of Medicine. Begun in 2007, this was the world’s first-in-human trial of gene therapy to treat an inherited […]


UCL Researchers Solve a Major Riddle of Retinal Degeneration Research for Retinitis Pigmentosa!

Mon, 26 Jan 2015 10:11:36 +0000

Today a paper published in Nature Communications from the Gene and Cell Therapy Group at the UCL Institute of Ophthalmology has shed light on why, until now, it has not been possible to effectively restore vision in rd1 mice – the world’s major model for retinitis pigmentosa (RP). The rd1 mouse is a model of […]


Phase I/II trial to assess safety and efficacy of viral RPE65 gene therapy

Phase I/II trial to assess safety and efficacy of viral RPE65 gene therapy for Leber congenital amaurosis

We began the world's first gene therapy trial in the eye in 2007.

The trial is to test the safety and efficacy of gene therapy using an adeno-associated virus (AAV) to deliver the RPE65 gene to retinal cells in patients who have Leber congenital amaurosis (LCA).

Initial results published in 2008 (Bainbridge et al. NEJM 2011) suggest that the technique is safe and can restore night-vision in some cases.

Further patients have been treated, and the latest arm of the study includes younger patients.

The encouraging results from this trial suggest that gene therapy can be an effective treatment for inherited retinal degeneration, and extensive evidence from laboratory research shows that other diseases that lead to blindness may also be treatable using gene therapy.

Each of these therapies requires the development of a new gene therapy vector and independent safety testing

Pipeline of gene therapy treatments for sight loss

The results of this trial indicate that gene therapy in the eye is safe and can be effective at treating sight loss.

We are developing a pipeline of gene therapy strategies for a range of other conditions that cause sight loss.
