A Single-Center Proof of Concept Pilot Study to Evaluate the Safety, Efficacy, and Tolerability of Sorafenib Combined With Therasphere in Subjects With Hepatocellular Carcinoma Awaiting Liver Transplantation.
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.
Interventional
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
To Evaluate sorafenib as an adjunct to Y-90 for control of HCC as a bridge/downstage to transplant
Subjects randomized to receive Sorafenib take the drug for 2 weeks before treatment with Y90. They have imaing (CT/MRI) 2 weeks after starting Sorafenib then are treated. Post-treatment patients have blood drawn and adverse event evaluation at 2 weeks, 4 weeks, 6 weeks, and then every 6 weeks up to 1 year or time of transplant. Repeat imaging is done at 4 weeks, and then every 3 months post-treatment. Subjects not receiving Sorafenib are terated with Y90 and then are evaluated post-treatment the same as the subjects that receive the drug.
Up to one year
