Transarterial Chemoembolization (TACE) Plus ABCB1 Inhibition Versus TACE Alone in Patients With Hepatocellular Carcinoma

Overview

IMPACT-TACE is an investigator-initiated, prospective, multicenter, randomized, double-blinded, interventional trial to test the hypothesis that the simultaneous application of doxorubicin with the ABCB1 inhibitor nicardipine would significantly improve the success rate of TACE treatment.

Liver cancer, also known as hepatocellular carcinoma (HCC), is the sixth most common tumor disease worldwide. It is an aggressive cancer that is very often fatal, as it is usually detected at a late stage when surgery is no longer possible. International guidelines recommend transarterial chemoembolization (TACE) as the treatment of choice in such cases, as this therapy can prolong survival. In such cases, international guidelines recommend transarterial chemoembolization (TACE) as the treatment of choice, as this therapy can prolong survival. TACE is a widely used interventional method in which a thin catheter is advanced to the liver artery supplying the tumor. Tiny beads loaded with a chemotherapeutic agent (doxorubicin) are then injected directly into the tumor nodules. The beads block the artery supplying the tumor, interrupting the blood supply to the tumor and causing it to die. In addition, the beads slowly release the chemotherapy drug doxorubicin into the tumor, which is intended to contribute to the complete death of the tumor cells. However, the studies also showed that complete death of the tumor node could only be achieved in approximately 25% of patients. The latest study results have revealed that one of the main causes of the incomplete response to TACE therapy is that cancer cells develop resistance to protect themselves against the chemotherapy drug doxorubicin. This resistance can be circumvented by inhibiting the enzyme ABCB1, allowing the chemotherapy drug to act on the tumor cells and kill them completely. The blood pressure medication nicardipine has a strong inhibitory effect on this enzyme. In this study, the investigators therefore want to investigate whether the response to TACE therapy can be improved by administering beads that release the active ingredient nicardipine in the tumor in addition to the chemotherapy drug doxorubicin, so that the tumor nodule cannot develop resistance and dies completely.
