About
The primary objective of this study is to answer the question "Is it possible to inject the COMBIG-DC vaccine in a hepatic tumor without getting unacceptable side effects"?
Full description
Patients diagnosed with hepatocellular carcinoma will get COMBIG-DC vaccinations at three occasions with 2-3 weeks and 3-5 weeks between vaccination 2 and 3 respectively. Adverse events will be registered until 6 months after last vaccination, as well as changes in vital signs (heart rate, blood pressure and body temperature) and lab parameters. Immunologic response will be evaluated by measuring immunologic markers in blood. The size of the tumor/tumors will be evaluated after 3 and 6 months and thereafter every three months until tumor progression.
For patients included after approval of Amendment 3 (2015-12-10), COMBIG-DC will be given as add on to standard treatment; sorafenib or Transarterial Chemoembolization (TACE).
