Estimated Enrollment: 21
Study Start Date: July 1998
Detailed Description:

PROTOCOL OUTLINE: This is a dose escalation study. Patients undergo a femoral arterial placement of a hepatic intraarterial catheter. Patients then receive adenoviral vector mediated gene transfer intravascularly over 30 minutes.

Cohorts of 3 patients each receive escalating doses of adenoviral vector until the maximum tolerated dose is determined.

Patients are followed at 3, 5, 7, 8, 15, and 29 days, at 2 months, and then every 3 months thereafter.

  Eligibility

Ages Eligible for Study:   18 Years to 69 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
