MeiraGTx Treats First Patient in XLRP Gene-Therapy Trial

MeiraGTx, a gene-therapy company in London and New York City, has treated its first patient in a gene-therapy clinical trial for people with X-linked retinitis pigmentosa (XLRP) caused by mutations in the gene RPGR. The Phase I/II study is taking place at Moorfields Eye Hospital in London. The safety-oriented trial will enroll 36 participants. Three dose levels of the therapy will be evaluated.

XLRP is a leading cause of inherited, progressive retinal degeneration and vision loss. The condition usually affects males, but is also diagnosed occasionally in females. Mutations in the gene RPGR cause about 70 percent of XLRP cases. RPGR mutations affect about 15,000 people in the United States and tens of thousands more around the world.

A Surprising Number of Carrier Females are Affected by X-Linked Retinitis Pigmentosa

Calico catX-linked retinitis pigmentosa (XLRP) is an inherited retinal disease causing significant vision loss, sometimes complete blindness, in males. Females are often considered to be unaffected carriers of the condition, with a 50 percent chance of passing XLRP to their sons.

Despite Blindness, the Peaches are Sweet in Paran

Ignacio, a farmer with RP, tends to his peach orchard in Peru.Paran, a village of 300 people tucked in the foothills of the Andes near Lima, Peru, is known for its sweet peaches, but also its high rate of blindness. About one in eight Paranos have lost their vision.

Until recently, the villagers never understood the cause of the affliction, though they suspected there might be a genetic component because it runs in families. However, most had never even received care from a doctor.

Getting the Right Diagnosis for a Retinal Disease

Research at the monitorDefinitive diagnoses for inherited retinal diseases don’t always come easy, even for the patients of the most knowledgeable doctors. Comments posted to this blog over the past year are a testament to that fact. Many readers are understandably frustrated by a doctor’s inability to determine exactly what retinal condition is affecting them or loved ones.
