Revolutionary Genetic Treatment Restores Sight for Individual Suffering from Rare, Previously Incurable Type of Blindness
Gene Therapy Shows Promising Results for Usher Syndrome Type 1b
A groundbreaking gene therapy has shown substantial improvement in vision for a 38-year-old man with Usher Syndrome type 1b, according to early clinical trial results [1][4]. This therapy, known as the "split gene therapy", uses a novel approach to deliver the large MYO7A gene, which is too big for traditional single AAV vectors [1][2].
The treatment involves the use of two AAV (Adeno-Associated Virus) vectors, each carrying a half of the MYO7A gene. These vectors deliver the split gene fragments to cells, where they recombine to restore the gene's function [2]. The researchers at the Telethon Institute of Genetics and Medicine (TIGEM) in Pozzuoli, Italy, were responsible for this innovative solution [2].
The man, who is the first patient in the world to receive this specific treatment, has reportedly experienced significant improvements in his vision. He can now recognize faces, navigate warehouse aisles at work, and read subtitles on TV due to his improved vision [4]. These improvements were noted in both near and distant vision, and even in low light conditions [4].
Mild, infrequent, and easily managed side effects were reported, but no specific details were given [4]. The improvements were observed as early as two weeks after the procedure and continued over time [1].
The gene therapy trial, involving eight patients, has shown promising results in restoring vision for a patient with Usher syndrome type 1b [1]. The trial is set to continue over the coming months, testing a higher dose of the treatment in seven more patients [1]. The trial is being conducted at the Center for Advanced Ocular Therapies at Vanvitelli University, one of the participating centers [1].
If the trial continues to show positive results, it could lead to a new treatment option for inherited eye diseases currently without any treatment options [4]. This method has the potential to treat other conditions caused by large genes that exceed conventional vector capacity [4].
The researchers are feeling positive about the trial's progress, but emphasize that it is still ongoing and a long road lies ahead before the therapy could be approved [1]. However, the preliminary results have generated cautious optimism among researchers [1].
