Siliphos in Advanced Hepatocellular Carcinoma

Completed · Phase 1

Conditions studied: Advanced Hepatocellular Carcinoma

In brief

Milk thistle is an herbal drug that may have some liver protection properties and may reduce inflammation in the liver. It may also have anticancer effects. However milk thistle is not approved by the Food and Drug Administration for any medical purpose in the United States. It has not been used in patients with liver cancer previously, to our knowledge, but there have been many studies of its use in patients with hepatitis and cirrhosis. Some of these studies have shown that milk thistle may help reduce elevated liver function tests. Siliphos is a derivative of milk thistle that can be absorbed better than some other types of milk thistle. The investigators would like to perform a study to identify doses of siliphos that are safe to take in advanced liver cancer and to identify positive or negative side effects this compound may have. The investigators will be using this information in future studies to see if siliphos can be used as a therapy in patients with advanced liver cancer to reduce elevated liver function tests.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥18 years
• ECOG performance score of 0-3
• Expected survival of >12 weeks
• Subjects with advanced HCC or locally advanced, unresectable HCC
• Elevated LFTs (including at least one of the following: TBili >1.5 times the upper limit of normal; serum AST >2.5 times the upper limit of normal
• HCC diagnosed/defined based on either biopsy, or by suggestive radiologic imaging according to the AASLD guidelines (arterial enhancement with venous washout) or an AFP >200 ng/ml
• Subjects must have measurable disease that can be accurately measured in at least one dimension (with at least >20mm diameter in the longest dimension by conventional imaging or >10 mm by helical CT)
• Elevated liver enzymes that are either due to underlying liver disease and/or tumor which is not amenable to stenting after discussion with interventional GI and/or IR
• Subjects must demonstrate an ability to understand the consent process and willingness to sign a written informed consent form
• Subjects must agree to use birth control pills or other active contraception during active study treatment

You may not qualify if…

• Pregnant women or women currently breastfeeding will be excluded from this study because the effects of silybin on pregnant women and/or nursing infants are not known
• Subjects must have < grade 4 hepatic toxicity
• Known brain metastases because of poor prognosis and as patients with brain metastases often develop neurological dysfunction that may confound evaluation of neurologic and other adverse side effects
• History of allergic reactions to the study medication
• Uncontrolled concurrent illness including, but not limited to: ongoing active infection (including SBP), symptomatic congestive heart failure, unstable angina, active cardiac arrhythmia, or psychiatric illness that would limit compliance with study requirements
