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.


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No


--Disease Characteristics-- Homozygous familial hypercholesterolemia, i.e.: Low-density lipoprotein (LDL) cholesterol greater than 500 mg/dL Autosomal dominant inheritance Early-onset tendon and tuberous xanthomas LDL receptor negative, i.e.: Receptor binding in cultured fibroblasts no more than 20% of normal OR Genotype with 2 previously described, disease-causing alleles Advanced coronary heart disease with relatively poor prognosis, i.e: Angina pectoris History of myocardial infarction Positive exercise tolerance test Atherosclerotic disease in proximal aorta or coronary arteries by ultrasound or angiogram None of the following: Unstable angina pectoris Left ventricular ejection fraction less than 30% Decompensated congestive heart failure Untreated ventricular tachycardia Moderate to severe aortic stenosis Other dyslipidemia Obstructive hepatobiliary disease

  • Prior/Concurrent Therapy At least 2 weeks since the following: Drugs affecting cholesterol metabolism Plasma exchange LDL apheresis --Patient Characteristics-- Age: Any age Renal: No azotemia No significant proteinuria Other: No hypothyroidism No diabetes
