Enrollment: 16
Study Start Date: September 2009
Study Completion Date: September 2011
Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: MVA-FCU1, flucytosine
    1. TG4023: single IT injection; possibility to re-administer once,

      • Percutaneous IT injections, under radiological or ultrasound imaging guidance
      • Dose-escalating schedule of administration: 107 pfu (Cohort #1), 108 pfu (Cohort #2) and 4x108 pfu (Cohort #3),
