Improved stability of lipiodol–drug emulsion for transarterial chemoembolisation of hepatocellular carcinoma results in improved pharmacokinetic profile: Proof of concept using idarubicin

Abstract : To investigate the relationship between the improved stability of an anticancer drug-lipiodol emulsion and pharmacokinetic (PK) profile for transarterial chemoembolisation (TACE) of hepatocellular carcinoma (HCC). The stability of four doxorubicin- or idarubicin-lipiodol emulsions was evaluated over 7 days. PK and clinical data were recorded after TACE with the most stable emulsion in eight unresectable HCC patients, after institutional review board approval. The most stable emulsion was the one that combined idarubicin and lipiodol (1:2 v:v). At 7 days, the percentages of aqueous, persisting emulsion and oily phases were 50-0-50, 33-0-67, 31-39-30, and 10-90-0 for the doxorubicin-lipiodol (1:1 v:v), doxorubicin-lipiodol (1:2 v:v), idarubicin-lipiodol (1:1 v:v), and the idarubicin-lipiodol (1:2 v:v) emulsion, respectively. After TACE, mean idarubicin C-max and AUC(0-24h) were 12.5 +/- 9.4 ng/mL and 52 +/- 16 ng/mL*h. Within 24 h after injection, 40 % of the idarubicin was in the liver, either in vessels, tumours, or hepatocytes. During the 2 months after TACE, no clinical grade > 3 adverse events occurred. One complete response, five partial responses, one stabilisation, and one progression were observed at 2 months. This study showed a promising and favourable PK and safety profile for the idarubicin-lipiodol (1:2 v:v) emulsion for TACE. aEuro cent Transarterial chemoembolisation (TACE) regimens that improve survival in hepatocellular carcinoma are needed. aEuro cent Improved emulsion stability for TACE resulted in a favourable pharmacokinetic profile. aEuro cent Preliminary safety and efficacy data for the idarubicin-lipiodol emulsion for TACE were encouraging.
