New treatment option for Homozygous Familial Hypercholesterolemia
Official title NGGT006 Gene Therapy for Homozygous Familial Hypercholesterolemia
ClinicalTrials.gov ID: NCT06125847
What this study is testing
What is NGGT006?
NGGT006 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for homozygous familial hypercholesterolemia.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This is an early phase 1, open-label, single-center, dose-escalation, pilot trial to evaluate the safety and efficacy of an intravenous infusion of NGGT006 in homozygous familial hypercholesterolemia (HoFH) patients with LDLR mutations. NGGT006 is an adeno-associated viral (AAV) vector carrying codon-optimized human LDLR gene, driving the expression of LDLR protein with normal function and promoting the clearance of low-density lipoprotein cholesterol (LDL-C).
