Gene therapy improves vision but does not halt progression of cell loss

Independent clinical trials, including one conducted at the Scheie Eye Institute at the Perelman School of Medicine, have reported safety and efficacy for Leber congenital amaurosis (LCA), a congenital form of blindness caused by mutations in a gene (RPE65) required for recycling vitamin A in the retina.

Researchers isolate elusive human gene that causes NMNAT1-related Leber congenital amaurosis

Researchers from the Massachusetts Eye and Ear Infirmary, The Children's Hospital of Philadelphia, Loyola University Chicago Health Sciences Division and their collaborators have isolated an elusive human gene that causes a common form of Leber congenital amaurosis (LCA), a relatively rare but devastating form of early-onset blindness. The new LCA gene is called NMNAT1.

EMA grants QLT positive opinions for Orphan Drug Designation of QLT091001 to treat inherited blindness

QLT Inc. today announced that QLT091001, an oral synthetic retinoid, has received positive opinions for two distinct Orphan Drug Designations by the European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP) for the treatment of the inherited retinal degenerative diseases, Leber Congenital Amaurosis (LCA) and Retinitis Pigmentosa (RP).

QLT's oral synthetic retinoid granted orphan drug designation for treatment of Leber Congenital Amaurosis

QLT Inc. today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation for QLT091001, its oral synthetic retinoid, for the treatment of Leber Congenital Amaurosis (LCA). LCA is an inherited progressive retinal degenerative disease that leads to retinal dysfunction and visual impairment beginning at birth. QLT091001 is an orally administered synthetic retinoid replacement for 11-cis-retinal, which is a key biochemical component of the visual retinoid cycle.

FDA grants QLT's QLT091001 orphan drug designation for treatment of Retinitis Pigmentosa

QLT Inc. today announced that QLT091001, the Company's oral synthetic retinoid, has been granted orphan drug designation for the treatment of Retinitis Pigmentosa (RP) from the U.S. Food and Drug Administration (FDA). This follows the FDA grant of orphan drug designation for QLT091001 for the treatment of Leber Congenital Amaurosis (LCA) also on December 7, 2010.

AGTC receives grant to evaluate Phase II Human Clinical Trial for LCA retinal disease

Applied Genetic Technologies Corporation, a privately-held, clinical stage biotechnology company developing novel systems to deliver human therapeutics, announces that it has received a grant of $1 million from the Food and Drug Administration (FDA Orphan Drugs Program). The grant will fund a Phase II Human Clinical Trial evaluating the safety and efficacy of a treatment for Leber congenital amaurosis (LCA), a genetic retinal disease known to cause blindness at an early age.

Scientists replace human gene to preserve photoreceptor function in retinal degeneration

The easy accessibility of the eye and the established link between specific genetic defects and ocular disorders offer hope for using gene therapy to provide long-term therapeutic benefit. Two reports in the current issue of Human Gene Therapy, a peer-reviewed journal published by Mary Ann Liebert, Inc., describe the effective replacement of a human gene to preserve photoreceptor function in a mouse model of severe retinal degeneration. The articles are available free online.

New study holds promise for patients with LCA

A new study led by Dr. Robert Koenekoop at the Montreal Children's Hospital at the McGill University Health Centre holds promise for certain patients with Leber congenital amaurosis, an inherited retinal degenerative disease that causes significant vision loss from birth. The study, sponsored by Canadian company QLT Inc., is designed to treat patients with LCA due to genetic mutations in either retinal pigment epithelium protein 65 or lecithin:retinol acyltransferase.

LCA: Few possess genetic mutation necessary for positive outcome from gene therapy

Leber congenital amaurosis (LCA) is a congenital retinal dystrophy present in approximately 1 of 80,000 births. It is estimated that about 3,000 people in the United States are living with LCA and will likely become blind in their lifetimes. Recently, there has been progress in gene therapy for this condition.
