    Interventional
  • Status

    Unknown status
  • Study Participants

    18
This is an open labeled, multiple centers, two countries (Taiwan and Korea) non-comparative phase I trial in patients with hepatocellular carcinoma. In phase I part, a maximum of 18 patients will be recruited in this study.
After screening, each eligible patient will undergo a treatment of OBP-301 within 14 days and will automatically enter follow-up period.

The follow-up period is up to 12 weeks after the last injection in the phase I part.

Each patient will return for follow-up visit weekly in the first month after the last injection, and then every 4 weeks up to the end of follow-up period.

Biological OBP-301

A range of dose levels is investigated and the starting dose is 1x1010 VP/tumor. Dose administration will be conducted through a dose-escalating scheme from 1x1010 VP/tumor to 1x1011 VP/tumor, 1x1012 VP/tumor, 3x1011 VP/tumor and 3x1012 VP/tumor.

single intra-tumoral injection Experimental

OBP-301 ; Cohort 1: 1x10 10 viral particle (VP)/ tumor Cohort 2: 1x10 11 viral particle (VP)/ tumor Cohort 3: 1x10 12 viral particle (VP)/ tumor
