Metabolic disorders such as argininosuccinic and glutaric aciduria, methylmalonic acidemia, homocystinuria or primary hyperoxaluria require specific diets to prevent the accumulation of substances that the body can’t process. Current treatments mainly focus on managing symptoms and metabolite levels, and do not always prevent the progressive deterioration caused by mutations associated with the condition. However, emerging gene therapies hold promise for transforming these diseases by targeting their underlying causes, as presented in the oral abstract session, “Gene and cell therapy for metabolic diseases” of the ongoing 28th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) meeting in New Orleans.

Zhejiang Doer Biologics Co. Ltd. has presented data regarding their FGF21R/GCGR/GLP-1R triple agonist DR-10624 for the treatment of metabolic dysfunction-associated steatohepatitis (MASH).

Immunity is not a function most people particularly associate with the liver. But because of its connection to the gut, the liver is exposed to bacterial metabolites as few other organs are. And when either the liver or the gut is not functioning well, it can adversely affect immunity as well. The liver is connected to the gut via both the biliary system and the portal vein. Those two conduits allow metabolites from the gut microbiome to influence what’s going on in the liver. Both liver and gut damage can affect this communication for the worse. And surprisingly, one of the consequences is immune dysfunction.

Genprex Inc. and University of Pittsburgh have entered into a new sponsored research agreement (SRA) to study GPX-002, Genprex’s gene therapy for diabetes in animal models of type 1 and type 2 diabetes.

“I’m a pediatrician in metabolic diseases, and every day in my clinical work I’m confronted with our lack in effective therapies for our patients.” That was the sobering introduction by Sabine Fuchs in her talk at the 2025 Congress of the European Association for the Study of the Liver in Amsterdam this week. The nature of metabolic diseases makes it difficult to develop treatments for them. “There are over 1,500 diseases known by now, and it is just very difficult to develop therapies for each and every individual rare disease.”

Mammoth Biosciences Inc. has nominated its first clinical development candidate – MB-111 – a potential one-time treatment for patients with very high triglycerides, including familial chylomicronemia syndrome (FCS) and severe hypertriglyceridemia. IND-enabling studies are on track to begin this year.

Adult skeletal muscle tolerates a lack of the coenzyme nicotinamide adenine dinucleotide (NAD), according to a study led by scientists at the University of Copenhagen. Their results suggest that adverse effects previously associated with congenital NAD depletion in this tissue may be due to impaired muscle development rather than to a deficiency of this molecule.
