  Purpose

OBJECTIVES:

I. Develop an approach for treating patients with homozygous familial hypercholesterolemia using gene therapy with autologous hepatocytes transduced with a normal low-density lipoprotein receptor gene.

Estimated Enrollment: 5
Study Start Date: June 1992
Detailed Description:

PROTOCOL OUTLINE: Autologous hepatocytes are obtained from a partial hepatectomy and transduced with a recombinant retroviral vector containing the low-density lipoprotein receptor gene. The transduced hepatocytes are infused via the inferior mesenteric vein 3 days following surgery.

Traditional therapy is discontinued for 4 weeks prior to protocol therapy and may resume 6 weeks after the hepatocyte infusion.
