NCT05860569 | RECRUITING | Hypertriglyceridemia, Familial

Safety Evaluation of Gene Therapy Drug in the Treatment of Primary Hypertriglyceridemic Patients With Recurrent Pancreatitis
Sponsor:

GeneCradle Inc

Brief Summary:

The study will evaluate safety and tolerance of intravenous delivery of GC304 gene therapy drug as a treatment of primary hypertriglyceridemic patients with previous onset of acute pancreatitis.

Condition or disease

Hypertriglyceridemia, Familial

Intervention/treatment

GC304

Phase

PHASE1

Detailed Description:

The purpose of this trial is to evaluate safety and tolerance of gene therapy drug GC304 in primary hypertriglyceridemic patients who have loss of function mutations in GPIHBP1 or LPL genes, with previous onset of acute pancreatitis. Open-label, dose-escalation clinical trial of GC304 will be conducted in China. GC304 will be administrated intravenously. Short-term safety will be evaluated in 52 weeks and enter long-term follow-up study of 5 years at will. Patients will be tested at baseline and followed up on various time points.
