institution.

- Have a diagnosis of metastatic liver cancer (MLC) or primary hepatocellular cancer
(HCC) confined to the liver.

- Be an appropriate candidate for receiving RFA as a medically indicated treatment.

- Have an echocardiogram revealing an Ejection Fraction (EF) ≥ 50%.

- Willing to return to the study site for their imaging scans.

- Have life expectancy of ≥ 3 months.

- Have ECOG performance status of 0-2 or Karnofsky score of 60-100% (see Appendix II).

- Have no more than Childs-Pugh Class B liver disease.

- Subjects must have no prior doxorubicin exposure.

- No single lesion should be > 7 cm in maximum diameter.

- Subjects must agree to receive no other systemic therapy from the time of study

Exclusion Criteria:

- Have serious medical illnesses including, but not limited to, congestive heart
failure, myocardial infarction or cerebral vascular accident within the last six

- Have PT or PTT > 1.5 times the institution's upper normal limit (UNL), except in
subjects who are therapeutically anticoagulated for non-related medical conditions
such as atrial fibrillation.

- Have platelet count > 75,000/mm3, absolute neutrophil count > 1500/mm3, or Hgb > 10
(unless the hemoglobin value has been stable, the subject is cardiovascularly stable,
asymptomatic and judged able to withstand the RFA

- Have serum creatinine ≤ 2.0 mg/dl (or calculated CrCl ≤ 60mL/min).

- Have contraindications to receiving doxorubicin HCl.

- Are being treated with other investigational agents (within a minimum of 30 days or 5
half-lives of the investigational agent).

- Have other concurrent malignancy (subjects with benign or non aggressive malignant
tumors-e.g.: squamous cell cancer of the skin-may be included), evidence of
extrahepatic cancer from their primary malignancy, or ongoing, medically significant
active infection.

- Documented HIV positive.

- NYHA class III or IV cardiovascular disease or LVEF < 50%.

- Evidence of hemachromatosis.

- Are on any of the medications listed in section 6.3, which could have an adverse
effect when combined with the study drug, and who cannot stop the medication for the
