Primary Outcome Measures:
  • Adverse Events [ Time Frame: Daily for the first 16 day, monthly thereafter for 6 months, 3-monthly since then ]

Secondary Outcome Measures:
  • Tumor response by WHO criteria [ Time Frame: at day 63 and months 4, 6, 9 y 12 ]

Enrollment: 10
Study Start Date: December 2002
Study Completion Date: March 2008
Primary Completion Date: November 2003 (Final data collection date for primary outcome measure)
Intervention Details:
    Genetic: TK99UN
    escalated dosis from 2x10e10 to 2x10e12 viral particles injected intratumorally
    Other Name: Adenoviral vector encoding for HSV-TK
Detailed Description:
The study is a phase I clinical trial evaluating the intratumoral injection of defective adenovirus containing HSVtk (the thymidine kinase of herpes simplex virus), in patients with advanced hepatocellular carcinoma that were not amenable to curative therapy. The study was conducted in a single center in Spain. Five consecutive cohorts of two patients received increasing doses of the vector by intratumoral injection and equal doses of either intravenous ganciclovir or oral valganciclovir. The dose received by each consecutive cohort of patients was progressively higher according to a prefixed scale.
