Details and patient eligibility

About

A research study to determine the safety, efficacy, and tolerability of Therasphere® (also known as Y-90, or Y-90 Therasphere) combined with or without sorafenib (Nexavar®), in patients with hepatocellular carcinoma (HCC, or liver cancer), awaiting liver transplantation.

Full description

Because Hepatocellular carcinoma (HCC) grows by forming new blood vessels liver transplant (OLT) offers the best chance for long term survival. However, with the growing number of patients who require OLT, prolonged wait list times often lead to drop out from the transplant list due to tumor progression. Some patients are granted an "upgrade",within the generally accepted guidelines for transplant eligibility, in order to expedite the access of patients with early HCC to transplantation before tumor progression. The use of therapies like radioembolization also known as Yttrium-90 ([Y-90] a procedure where very small beads coated with radiation are injected directly into the tumor through an artery in your groin) while awaiting OLT has become common at most transplant centers, including Northwestern, to help patients reach transplant. Additionally, these treatments are being used to move patients to a status eligible for transplant. We are studying whether a combination approach with systemic therapy and therapy applied directly to the liver, will be more successful than a single therapy . Angiogenesis (a process involving the growth of new blood vessels from pre-existing vessels) plays an important role in the early stages of HCC. A decrease in angiogenesis both locally within the treated tumor as well as in any existing tumor cells, not yet detected, would hopefully decrease the incidence of post transplant recurrence of HCC. All subjects enrolled in this study will be treated with the use of Therasphere, Y-90, which is composed of nonbiodegradable glass microspheres coated with the radioactive compound Y-90 which are injected into the hepatic artery. The concentrated radioactive microspheres within the tumor lead to "inside-out" radiation. Half of the subjects will be treated with sorafenib (NEXAVAR®) in conjunction with Y-90. The determination of which subjects will receive sorafenib will be made randomly, like the flip of a coin. Sorafenib works by slowing the growth of the tumor cell , attacking the tumor from the outside. Researchers hope to determine whether the subjects treated with sorafenib have an overall improved response to liver directed therapy with Y-90 Therasphere.

Enrollment: 24 patients

Inclusion criteria

• Adult > 18 years olf of either gender
• Diagnosis of HCC confirmed by biopsy, CT, or MRI
• Able to carry out activities of daily living, awake >50% of waking hours
• Meets eligibility for liver transplantation
• No prior treatment for HCC
• Ability to understand and sign the informed consent
• Child-bearing women and any men agree to use two forms of birth control (one of which should be a barrier method) during the course of therapy and for 8 weeks afterward.

Exclusion criteria

• Less than or = 18 years old
• Ineligible for transplant due to comorbid disease
• Renal Failure requiring dialysis of any kind
• Severe Cardiac disease
• History of a stroke
• Evidence of metastatic disease- or tumors that have spread outside the liver
• Known human immunodeficiency virus (HIV) infection
• Uncontrolled blood pressure (systolic > 160) despite medication(s)
• Major surgery within 4 weeks prior to the screening visit
• Active clinically serious infection
• Serious non-healing wound, ulcer, or bone fracture.
• History of gastrointestinal bleeding (GIB) within 6 weeks prior to the screening visit
• Prior transplant of any kind
• Must be able to swallow oral pills, tablets or capsules of any size
• Use of St. John's Wort or rifampin (rifampicin).
• Currently being treated with Interferon and/or Ribavirin therapy due to the thrombocytopenias, lymphopenias and anemias observed with use of these two medications.
• Known or suspected allergy to sorafenib or any agent given in the course of this trial.
• Any malabsorption problem
• Pregnancy or lactation. Women of childbearing potential must have a negative pregnancy test 7 days prior to beginning therapy.
• No potential living donor transplant (LDT-donor identified and worked up by the time of randomization into this study. If a living donor is later identified- the subject will be allowed to continue in the study. Sorafenib will be stopped at a minimum of 7 days prior to transplant surgery.
• Active alcohol use, drug use, or a psychiatric disease that would, in the opinion of the PI or a subinvestigator (sub-I), prevent the subject from complying with the study protocol and/or endanger the subject during their participation in the study
• Inability of the potential subject to read, understand and sign the informed consent document
