Experimental treatment

Several cellular processes, particularly those related to lysosome function and autophagy, are altered in the muscles of people with late-onset Pompe disease (LOPD), and supplementation with an amino acid as a regulator could be a “promising therapeutic approach,” according to a study. Levels of L-arginine, an amino acid that…

The U.S. Food and Drug Administration (FDA) has cleared Aro Biotherapeutics to conduct a Phase 1 clinical trial to test ABX1100, its experimental substrate reduction therapy, in people with late-onset Pompe disease (LOPD). The clearance of Aro’s investigational new drug (IND) application comes as the company is…

Dyne Therapeutics has unveiled promising preclinical data for its enzyme replacement therapy (ERT) FORCE-GAA — part of the company’s propriety FORCE platform — designed to treat Pompe disease. The novel therapy has demonstrated the potential to deliver the treatment directly to skeletal and heart muscles, as well…

Researchers in the U.S. used a gene-editing tool in the lab to correct mutations known to cause infantile-onset Pompe disease, and this enabled patient-derived cells to produce a working version of the acid alpha-glucosidase (GAA) enzyme they lacked. The approach “may offer an efficacious, long-term therapy,” the researchers wrote,…

A gene therapy designed to travel into muscles resulted in widespread production of the enzyme that’s missing or faulty in Pompe disease, according to a study that also describes a new rat model of the infantile-onset form of the disease. Researchers also observed that rats given a single…

Mitochondria dysfunction is linked to hypertrophic cardiomyopathy — when the heart becomes enlarged and cannot pump blood efficiently — in people with Pompe disease, according to a new study from China. The disease-causing mechanisms were explored in a patient-derived heart cell model with characteristics of Pompe disease, including low…

A stem-cell based gene therapy that’s modified for better entry into muscle cells was seen to normalize protein levels in the skeletal muscle tissue of a mouse model of Pompe disease, according to a new report. The Pompe mice exhibited altered levels of hundreds of proteins — including ones…

The first healthy volunteer has been enrolled in a Phase 1 study testing ABX1100 — a novel substrate reduction therapy from Aro Biotherapeutics — as a treatment for Pompe disease. This will be the first-in-human trial for the experimental therapy, meaning it’s the first time ABX1100 has been…

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…

Treatment with AT-GAA, Amicus Therapeutics’ experimental two-part therapy for Pompe disease, has now been shown to improve motor function, and to stabilize or improve lung function, for up to four years in adults. That’s according to new analyses from the ongoing Amicus-sponsored Phase 1/2 ATB200-02 trial…
