American Society of Clinical Oncology (ASCO) Publishes Abstract of SIRveNIB, an Investigator-led Asia Pacific Primary Liver Cancer Study to be Presented at ASCO Annual Meeting in Chicago, 4 June 2017

Geschrieben am 18-05-2017

Singapore (ots/PRNewswire) -

The SIRveNIB abstract published on-line in the Journal of Clinical
Oncology states that treatment of locally advanced Hepatocellular
Carcinoma (HCC) with a single treatment of SIR-Spheres® Y-90 resin
microspheres results in Overall Survival not significantly different
from twice-daily oral sorafenib, but with significantly better tumour
response and fewer and less severe adverse events

The study was conducted by The Asia-Pacific Hepatocellular
Carcinoma Trials Group (AHCC) in collaboration with the National
Cancer Centre Singapore and Singapore Clinical Research Institute
(SCRI) and supported by the National Medical Council Singapore and
Sirtex Medical Limited

The lead author of the SIRveNIB abstract, Professor Pierce Chow,
Senior Consultant Surgeon at the National Cancer Centre Singapore and
the Singapore General Hospital, reported that: "Asia Pacific patients
with locally advanced primary liver cancer (HCC or hepatocellular
carcinoma) with no spread (metastases) outside the liver who are
treated with Y-90 resin microspheres have a significantly better
tumour response rate (TRR) compared to sorafenib, despite 28.6%
(n=52) of patients not receiving Y-90 therapy as planned (TRR - 16.5%
for Y-90 resin microspheres vs 1.7% for sorafenib, respectively; p <
0.001). Moreover, patients experienced fewer, less serious adverse
events when compared with those treated with sorafenib. There were no
statistically significant differences in the primary endpoint of
overall survival (OS) between the two treatments."

Although the median OS in the intent-to-treat group[1] was 8.54
months for Y-90 resin microspheres vs. 10.58 months for sorafenib,
respectively (p=0.203), there was a trend in improvement in median OS
in the treated group[2] for Y-90 resin microspheres (11.27 vs. 10.41
months, p=0.273). While Y-90 resin microspheres were not superior to
sorafenib regarding OS, Professor Chow, who is also Professor and
Course Director at the Duke-NUS Medical School, indicated that "the
better tumour response and tolerability of Y-90 resin microspheres
offers a compelling treatment alternative for patients with advanced
hepatocellular carcinoma, for whom there are limited treatment
options available."

SIRveNIB was designed to compare the efficacy and safety of
selective internal radiation therapy (SIRT) with yttrium-90 [Y-90]
resin microspheres (SIR-Spheres; Sirtex Medical Limited, North
Sydney, Australia) versus sorafenib (Nexavar®; Bayer HealthCare
Pharmaceuticals, Berlin, Germany), a systemic treatment that is the
current standard of care in advanced hepatocellular carcinoma. The
patients in SIRveNIB were ineligible for potentially curative
therapies, such as surgical resection, ablation or liver
transplantation.

"Each year we are making good progress in treating liver cancer.
The deeper we go in our research the better we are able to understand
how the cancer behaves and we are able to widen the treatments
options for our patients. The results reinforced our belief that with
the right people on the research project, we can get the best
results. I am grateful to our partners for collaborating in this
study," added Professor Soo Khee Chee, Director of NCCS.

"Completion of the investigator-led SIRveNIB study represents a
significant milestone in Asia Pacific liver cancer research, and
underscores the strong private-public partnership that exists between
Sirtex Medical Limited, the National Cancer Centre Singapore and
Singapore Clinical Research Institute. We look forward to the
presentation of more complete results of SIRveNIB at the impending
ASCO Annual Meeting," said Associate Professor Teoh Yee Leong, CEO
Singapore Clinical Research Institute. "This is the first time we
have completed such a large-scale investigator-led clinical trial in
the Asia Pacific region, whose results will be beneficial to liver
cancer patients in our region."

About Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the most common form of primary
liver cancer - cancer that starts in the liver - which is the sixth
most-common cancer in the world and the second most-common cause of
cancer-related death.[3] It affects mainly patients with cirrhosis
from any cause, including viral hepatitis and alcohol abuse. HCC
occurs with greatest frequency in regions where hepatitis is most
often diagnosed, such as in the Asia Pacific region and Southern
Europe. When diagnosed in its early stages, HCC can be treated by
surgical resection, ablation or liver transplantation with
expectation of improved long-term survival. However, these options
are not available to the great majority of patients. For patients
with unresectable HCC, the outlook is bleak, with survival ranging
from a few months to about two years depending largely on the extent
of their tumours and state of their liver at the time of
diagnosis.[4] No new HCC treatment option has been tested
successfully in large studies for almost a decade.
