Safety and efficacy analysis of in vivo lentiviral gene therapy in pre-clinical ARC syndrome models.

Gene therapy rescued a fatal liver disorder in mice, setting the stage for human trials of this potential cure for a rare childhood disease.

In vivo liver-targeted lentiviral gene therapy safely and effectively rescued key features of ARC syndrome (a rare, early-lethal disorder of bile flow and liver disease) in a mouse model, with improved survival, growth, and liver function. Published in Nature Communications, this preclinical study from Great Ormond Street/UCL supports advancing toward clinical gene therapy for ARC.
