OLYSIO™ (simeprevir): Quick Facts -- What You Need to Know

November 24, 2013
By Patricia Emory

OLYSIO™ (simeprevir) was approved in the United States November 22, 2013 by the FDA for the treatment of hepatitis C patients in conjunction with pegylated interferon and ribavirin in adult patients (treatment-naive and treatment-experienced) with genotype 1 including those with compensated cirrhosis.

OLYSIO™ (simeprevir) is a “2nd generation”  NS3/4A protease inhibitor which acts by blocking the protease enzyme that enables the virus to replicate.

Dosing and Duration of treatment

Dosing: Fixed dose of 150mg once a day

Duration of Treatment:

Treatment-naïve and prior-relapsers: 12 weeks of Simeprevir in combination with 24 weeks of pegylated interferon and ribavirin

Partial and null-responders: 12 weeks of Simeprevir in combination with 48 weeks of pegylated interferon and ribavirin

Adverse Effects

The most common adverse effects of Simeprevir are rash and sensitivity to sunlight (most common in the first 4 weeks of treatment) as well as those associated with pegylated interferon and ribavirin.

Q80K polymorphism

Q80K polymorphism is found in 56.7% of genotype 1a patients in the US. The Q80K polymorphism  greatly reduces treatment response. It is suggested that all patients being considered for treatment using Simeprevir be screened for the Q80K polymorphism.

Novel Patient Stratification Biomarkers for Liver Cancer

Novel Patient Stratification Biomarkers for Liver Cancer

20th November, 2013. Proteome Sciences is pleased to announce the discovery and validation
of novel protein biomarkers for patient stratification in liver cancer using proprietary proteomics workflows. Details are published today in the journal EuPA Open Proteomics: “Protein expression profiles of chemo-resistant mixed phenotype liver tumors using laser microdissection
and LC–MS/MS proteomics”
The study was performed in partnership with Professor Nigel Heaton and his team at Kings
College Hospital NHS Foundation Trust and used PS Biomarker Services™ leading edge
proteomic workflows.

Effective treatment of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) remains
one of the toughest challenges for doctors, with a five year survival rate of only 13%, barely  \improved since the 1970’s. Prior to the discovery of these biomarkers, definition of the sub-types
of liver cancer which require different treatment options, has been extremely difficult.

After completing the analysis of 2,864 proteins, a panel of differentially expressed biomarkers  was identified and patents were filed prior to publication to cover these novel stratification  markers.

Commenting on the EuPA publication Professor Nigel Heaton, Director of the King’s Liver
Transplant Centre said:-

“The biomarkers published in EuPA Open Proteomics represent a major step towards improving
the outcomes in the treatment of liver cancer. We have been waiting for over 30 years for better
treatment options in liver cancer and a large part of the challenge has been the lack of effective
biomarkers to differentiate hepatocellular carcinoma and cholangiocarcinoma. Proteome  Sciences’ proprietary workflows for FFPE tissue for the first time provided a highly effective  way of identifying biomarkers for liver cancer and we need to accelerate further validation  before moving to widespread clinical adoption.”

Dr. Ian Pike, Chief Operating Officer of Proteome Sciences added:-

“Stratified medicine is a key component of the global response to major healthcare challenges
that urgently requires new biomarkers to guide early diagnosis and treatment selection. The
results from this study show the value of Proteome Sciences' proteomics technologies in  discovering and validating biomarkers for stratified medicine in liver cancer. We have additional
studies ongoing where our SysQuant® technology is defining high content cell signalling
pathway maps in pancreatic and liver cancers that will guide optimal drug selection and should
considerably improve and deliver better patient outcomes.”

Keywords: 3-nitrotyrosine;  fitness to drive;  minimal hepatic encephalopathy;  psychometric tests


Background & Aims

Cirrhotic patients with minimal hepatic encephalopathy (MHE) show impaired driving ability and increased vehicle accidents. The neurological deficits contributing to impair driving and the underlying mechanisms are poorly understood. Early detection of driving impairment would help to reduce traffic accidents in MHE patients. It would be therefore useful to have psychometric or biochemical parameters reflecting driving impairment. The aims of this work were as follows: (i) to shed light on the neurological deficits contributing to impair driving; (ii) to assess whether some psychometric test or biochemical parameter is a good indicator of driving impairment.


We assessed in 22 controls, 36 cirrhotic patients without and 15 with MHE, driving performance using a driving simulator (SIMUVEG) and Driver Test. MHE was diagnosed using the psychometric hepatic encephalopathy score (PHES). Psychometric tests assessing different neurological functions (mental processing speed, attention, visuo-spatial and bimanual coordination) were performed. Blood ammonia and parameters related with nitric oxide-cGMP metabolism, IL-6, IL-18 and 3-nitrotyrosine were measured.


Patients with MHE showed impaired driving ability correlating with MHE grade, with impaired vehicle lateral control in spite of reduced driving speed. Patients with MHE show psychomotor slowing, longer reaction times, impaired bimanual and visuo-spatial coordination and concentrated attention and slowed speed of anticipation and increased blood ammonia, cGMP, IL-6, IL-18 and 3-nitrotyrosine.


Impaired mental processing speed, attention and alterations in visuo-spatial and motor coordination seem main contributors to impaired driving ability in patients with MHE. Increased serum 3-nitrotyrosine is associated with impaired driving ability.
