Clinical Trial
Data to be Presented at The Liver Meeting®
2012 in Boston
BOSTON, Nov.
11, 2012 - GlobeImmune, Inc., today announced Phase 2b
clinical data showing that GI-5005, a Tarmogen® product
candidate for the treatment of chronic hepatitis C virus (HCV)
infection, improved virologic clearance of HCV in combination with
pegylated-interferon plus ribavirin (P/R) in genotype 1, IL28B T/T
patients. IL28B T/T is an unfavorable patient genotype that
predicts poor sustained virologic response (SVR24) to P/R.
GI-5005-02 is a randomized Phase
2b clinical trial evaluating GI-5005 plus P/R compared to P/R alone
in subjects with chronic genotype 1 HCV infection.
Preliminary data from the trial showed that the largest
improvement in SVR24 was observed in subjects with the most
difficult-to-treat IL28B T/T genotype. GI-5005 enhanced
HCV-specific cellular immunity and improved SVR24 [GI-5005+P/R: 3/5
(60%) compared to P/R alone: 0/5 (0%)].
Following this result, the trial
was expanded to enroll and treat an additional 17 genotype 1,
treatment-naïve subjects having the IL28B T/T genotype. In
the study, presented by Dr. M. L. Shiffman, the Liver Institute of
Virginia, Bon Secours Virginia Health System, Newport News, VA,
GI-5005 in combination with P/R was well tolerated and had a higher
end of treatment virologic response rate [GI-5005+P/R; 10/16 (63%)
compared to P/R alone; 3/11 (27%)].
"GI-5005 in combination with
pegylated interferon + ribavirin appears to have an effect in the
most difficult-to-treat IL28B patients," said Dr. Shiffman.
"GI-5005 could potentially be used in treatment refractory HCV
patient subgroups in future regimens."
GI-5005 contains a fusion of two hepatitis C
proteins, NS3 and Core, which are highly conserved across HCV
genotypes and are recognized by T cells. GI-5005 is engineered to
activate an HCV-specific T cell immune response, resulting in the
reduction of cells containing viral antigens.
The World Health Organization estimates that up to
170 million people globally are infected with HCV, with three to
four million new infections each year. Approximately 20% to 30% of
all HCV patients will face life-threatening complications as a
result of their disease. In industrialized countries, HCV accounts
for 40% of cases of end-stage cirrhosis, 60% of cases of
hepatocellular carcinoma and 30% of liver transplants.
About
GlobeImmune
GlobeImmune is a biopharmaceutical
company focused on developing therapeutic products for cancer and
infectious diseases based on its proprietary Tarmogen®
platform. Tarmogens activate the immune system by stimulating
cellular immunity, known as T cell immunity, in contrast to
traditional vaccines, which stimulate predominately antibody
production. To date, Tarmogen product candidates have been
generally well tolerated in clinical trials for multiple disease
indications and are efficient to manufacture. In May
2009, the company entered into a collaboration agreement with
Celgene Corporation focused on the discovery, development and
commercialization of product candidates for the treatment of
cancer. In October 2011, the company entered into a worldwide,
strategic collaboration with Gilead Sciences, Inc., to develop
Tarmogens for the treatment of chronic hepatitis B infection. For
