Astellas Gene Therapies

FORTIS, a Phase 1/2 clinical trial of an experimental gene therapy called AT845, is due to restart in adults with late-onset Pompe disease (LOPD), thanks to a decision by the U.S. Food and Drug Administration (FDA). The trial was put on hold mid-2022 after one of its…

The U.S. Food and Drug Administration (FDA) has placed a clinical hold on the FORTIS Phase 1/2 trial of AT845, a single-dose gene therapy for adults with late-onset Pompe disease (LOPD). The decision was due to a study participant developing peripheral sensory neuropathy — nerve damage outside the brain…

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…

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…
