Official title
Master Protocol for a Phase I/II Open-label Safety and Efficacy Study of LNP.UCD.ABE, a Lipid Nanoparticle-delivered Base Editing Therapy, in Patients With Urea Cycle Disorders Due to Variants Amenable to Corrective Editing by LNP.UCD.ABE
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a single-site Phase 1/2 open-label umbrella clinical trial designed to evaluate the safety, tolerability, and efficacy of a single intravenous dose of LNP.UCD.ABE in 5 pediatric subjects with severe infantile-onset UCDs. This is a master clinical protocol in which subjects with a variant in a urea cycle disorder (UCD) gene (CPS1, OTC, ASS1, ASL, ARG, NAGS, or SLC25A15) that is demonstrated to be amenable to corrective editing by an adenine base editor (ABE) would be eligible for enrollment.
