About

This study evaluate activity and safety profile of weekly Genexol-PM in patients with advanced hepatocellular carcinoma for whom sorafenib treatment failed. Patients will receive Genexol-PM on days 1, 8, and 15 every 4 weeks.

Full description

Hepatocelluar carcinoma (HCC) is a highly vascular neoplasm characterized by arterial enhancement on CT or MRI. Angiogenesis provides a target for novel prognostic and therapeutic approaches to HCC. Sorafenib is the standard 1st-line therapy shown to significantly improve overall survival in advanced HCC. However, sorafenib benefits are mostly transient and modest. In addition, sorafenib is associated with major toxicities, and about 30% of patients stop it because of intolerance. Effective therapies are needed for patients who experience progression during or after receiving sorafenib or who have sorafenib intolerance. Paclitaxel has an antiagiogenic activity and weekly administration of paclitaxel is considered to have enhanced efficacy over 3-weekly administration due to greater drug exposure or a direct antiangiogenic effect. A previous phase I study showed that weekly paclitaxel has activity in hepatocellular carcinoma and further investigation in phase II trials is warranted. Genexol-PM, a cremophor-free, polymeric micelle-formulated paclitaxel, is believed to be superior to conventional paclitaxel in terms of the obviation of premedication and the delivery of higher paclitaxel doses without additional toxicity.

Inclusion criteria

1. A diagnosis of hepatocellular carcinoma (HCC) based on either

   1. histopathologic or cytologic findings
   2. a diagnosis of cirrhosis and HCC with classical imaging characteristics (at least a 3-phase liver protocol CT or MRI and a lesion that demonstrates arterial enhancement and washes out in the venous phase)

2. Previous sorafenib treatment for at least 14 days and discontinuation of sorafenib treatment prior to inclusion

3. Radiologic confirmation of disease progression during or after discontinuation of sorafenib treatment or discontinuation of sorafenib due to intolerance despite appropriate supportive care

4. Barcelona Clinic Liver Cancer (BCLC) stage C or BCLC stage B disease not amenable to locoregional therapy or refractory to locoregional therapy

5. ≥ 1 measurable lesion according to RECIST Version 1.1

6. ≥ 20 year of age

7. ECOG performance status ≤ 2

8. Child-Pugh score ≤ 7

9. Informed consent prior to study

10. Adequate organ function

    1. Hepatic: bilirubin ≤ 1.5 times upper limit of institutional normal value (ULN), AST or ALT ≤ 5 x ULN
    2. Renal: estimated creatinine clearance ≥ 60 mL/min
    3. Hematologic: hemoglobin ≥ 9 g/dL, absolute neutrophil count (ANC) ≥ 1,500/μL, platelets ≥ 75,000/μL (In case of thrombocytopenia associated with hypersplenism in chronic liver disease, platelets ≥ 50,000/μL is allowed for participation at the physician's discretion.)
    4. Coagulation: prothrombin time (INR) ≤ 1.5, partial thrombin time (PTT) ≤ 5 seconds above the ULN

Exclusion criteria

2. A history o f or current hepatic encephalopathy or clinically meaningful ascites
3. Grade 2 or more peripheral neuropathy
4. Prior liver transplant
5. History of any other cancer within 2 years (Patients with carcinoma in situ of any origin and patients with prior malignancy who are in remission and whose likelihood of recurrence is very low, may be eligible.)
6. A history of treatment with taxanes (paclitaxel or docetaxel)
7. Females who are pregnant or lactating
8. A know allergy or hypersensitivity reaction to any of the treatment components
9. Serious preexisting medical conditions that cannot adequately controlled with appropriate therapy
