Hepatocellular Carcinoma
Conditions
Brief summary
This is a single-center, single-arm, open-label, prospective phase 2 trial to assess the efficacy of localized concurrent chemoradiation therapy (CCRT) and sorafenib sequential therapy in subjects with advanced HCC. Approximately 47 subjects will be enrolled and will receive CCRT and sorafenib sequentially until all-cause mortality.
Detailed description
This is a single-center, single-arm, open-label, prospective phase 2 trial to assess the efficacy of localized concurrent chemoradiation therapy (CCRT) and sorafenib sequential therapy in subjects with advanced HCC. Approximately 47 subjects will be enrolled and will receive CCRT and sorafenib sequentially until all-cause mortality. Sorafenib is the current standard of care for advanced hepatocellular carcinoma (HCC) patients following clinical results from the two pivotal trials in Western and Asian patients. The median overall survival in patients with unresectable hepatocellular carcinoma (HCC) who are treated with sorafenib have shown to be approximately 14 months. However in the presence of portal vein invasion or extrahepatic metastases, the median overall survival is significantly lowered to 5.6 - 8.9 months. Going forward, improvement in patient-related outcomes would be highly desirable. A pilot study has been conducted in subjects with advanced HCC with portal vein invasion for which effective therapeutic methods have not been established. This was a single-center, open-label study of localized concurrent chemoradiation therapy (CCRT) for locally advanced HCC patients with portal vein invasion. A total of 40 subjects with advanced HCC with portal vein invasion were enrolled. The subjects were treated with a total of 45 Gy of external beam radiotherapy (1.8 Gy per session, 5 sessions a week, for 5 weeks), with hepatic arterial infusion of 5-flourouracil (5-FU) during the first and last 5 days of radiation therapy (5-FU 500 mg infusion for 5 hours) through the pre-inserted chemoport. Eighteen (45%) subjects had an objective tumor response at 1 month after completion of localized CCRT. The 3-year survival rate was 24.2% and median overall survival was 13.1 months. Treatment-related serious adverse events (CTCAE grade 3 or higher) were anemia, leukopenia, thrombocytopenia, mucositis and liver decompensation, and their rates were 2.5%, 2.4-5.0%, 17.5%, 10% and 7.3-17.5%, respectively. In addition, 2.4-5.0% of adverse events were chemoport-related adverse events including infection and port obstruction. Although sorafenib has been shown to increase overall survival in advanced HCC patients as compared to placebo through anti-angiogenesis effect, its tumoricidal effect is not evident. Meanwhile, based on the above analysis from the pilot study, localized CCRT has been regarded as a promising treatment with tumoricidal effect for advanced HCC patients. Therefore, combining sorafenib treatment with CCRT is anticipated to augment anti-tumor effect and improve tumor response and median overall survival.
Interventions
RADIATIONCCRT
The subject is treated with a total of 45 Gy of external beam radiotherapy (1.8 Gy per session, 5 sessions a week, for 5 weeks), with hepatic arterial infusion of 5-flourouracil (5-FU) during the first and last 5 days of radiation therapy (5-FU 500 mg infusion for 5 hours) for radiosensitization through the pre-inserted chemoport.
DRUGsorafenib
Four weeks after completion of CCRT, the subject is given daily sorafenib treatment and will be followed for survival.

Exclusion criteria
* Significant liver function impairment, defined as bilirubin \> 3.0 mg/dL or uncontrolled ascites * Imaging findings for HCC corresponding to any of the following: 1) Diffuse HCC with \> 50% liver occupation, that is not adequate for external radiotherapy, 2) Presence of metastatic lesions that measure ≥ 1.0 cm in the long axis * Uncontrolled significant active infection * Presence of active malignancy (except for HCC) * Females who are lactating or pregnant; females of childbearing potential who have not received pregnancy test or shown positive on pregnancy test * Any medical or other condition that in the opinion of the investigator would preclude the subject's participation in a clinical study * Major surgery within 4 weeks prior to enrollment
