gene therapy

A new gene therapy for Pompe disease showed promise in a mouse model, researchers say, fully clearing in muscles the buildup of glycogen that characterizes the genetic disorder and also reducing it nearly completely in the brain. Glycogen is the stored form of glucose, or sugar — the body’s…

Certain protein modifications may enhance the ability of a therapeutically-delivered acid alpha-glucosidase (GAA) enzyme to be secreted and taken up by neighboring cells in models of Pompe disease, a study suggested. Such approaches could offer ways to improve the effectiveness of gene therapies for Pompe, although more work is…

The investigational gene therapy ACT-101 overall was well-tolerated among three people with late-onset Pompe disease (LOPD) who were treated in a Phase 1/2 clinical trial. Moreover, the trial results also showed that treatment markedly increased levels of the GAA enzyme — deficient in Pompe disease — in the patients’ muscle…

Acceptable safety is being seen to date in four adults with late-onset Pompe disease (LOPD) given the one-time gene therapy  AT845 in the FORTIS Phase 1/2 trial, its developer, Astellas Gene Therapies, announced. Interim study data in these four enrolled patients, as of the Dec. 3 cutoff date, shows…

An investigational gene therapy called AT845 could effectively increase the activity of an enzyme that’s deficient in mouse and nonhuman primate models of Pompe disease, according to a study. The research also highlights potential complications that can occur when gene therapies designed for use in humans are tested in…

Gene therapy given with chaperones — specific molecules known to stabilize the structure of proteins — was found to enhance the availability of acid alpha-glucosidase, known as GAA, the missing or defective enzyme in Pompe disease (PD), in a mouse model. The treatment subsequently eased disease symptoms, with the…

A new enzyme replacement therapy (ERT) targeting specific cell types boosts the delivery of acid alpha-glucosidase (GAA) — the enzyme missing or defective in Pompe disease patients — to muscle and heart cells, a study shows. Compared to standard ERT, the targeted approach by Regeneron Pharmaceuticals normalized the…

The first patient has been dosed in the FORTIS Phase 1/2 trial of AT845, a single-dose gene therapy for adults with late-onset Pompe disease (LOPD). AT845 is designed to deliver a healthy copy of the gene that encodes the enzyme acid alpha-glucosidase (GAA) directly to…

A Phase 1/2 trial is recruiting adults in the U.S. who have late-onset Pompe disease to test a gene therapy, AT845, being developed by Audentes Therapeutics, according to an update from the Muscular Dystrophy Association. The company-sponsored FORTIS trial (NCT04174105) will be evaluating the safety…

Rare Disease Day at NIH, organized by the National Institutes of Health (NIH) and taking place on March 1, will feature panel discussions, patient stories, research updates, TED-style talks, and a presentation by a Nobel laureate recently recognized for her work on a gene editing tool. The free, virtual…
