About TheraSphere® 

TheraSphere is a liver cancer therapy that consists of millions of
small glass beads (20 to 30 micrometers in diameter) containing
radioactive yttrium-90 (Y-90). The product is injected by
physicians into the main artery of the patient’s liver through a
catheter, which allows the treatment to be delivered directly to
the tumour via blood vessels.

TheraSphere is approved by the U.S Food and Drug Administration
under a Humanitarian Device Exemption (HDE). HDE approvals are
based on demonstrated safety and probable clinical benefit.

TheraSphere treatment can generally be administered on an
outpatient basis and does not usually require an overnight hospital
stay. TheraSphere, reimbursed by Medicare and a number of major
commercial health insurers in the U.S., is used to treat patients
with unresectable hepatocellular carcinoma (HCC) and can be used as
a bridge to surgery or transplantation in these patients. It can
also be used to treat primary liver cancer patients with portal
vein thrombosis.

Common side effects include mild to moderate fatigue, pain and
nausea for about a week. Physicians describe these symptoms as
similar to those of the flu. Some patients experience some loss of
appetite and temporary changes in several blood tests. For details
