Mean Change From Baseline in Liver Biopsy Immunohistochemical Marker of Hepatic Stellate Cell (HSC) Activation and Collagen Synthesis at Week 52
Query!
Assessment method [1]
0
0
A percutaneous liver biopsy was obtained at the screening visit and at Week 52. A new liver biopsy at the screening visit was not taken in the event that a previous liver biopsy taken within 120 days of the Baseline /Day 1 visit (day of first dose), and the tissue block was available. The immunohistochemical marker assessed was smooth muscle alpha-actin (aSMA). Sections of the liver biopsies were stained by standard immunocytochemical techniques using a monoclonal antibody to smooth muscle actin with 'very intense purple' as the detection chromogen. This gives a reddish-purple color to the activated stellate cells, which strongly contrasts with the rest of the tissue. Change from Baseline was calculated as the post Baseline assessment minus the Baseline assessment for a given parameter. If either the Baseline or on-treatment value was missing, the change from Baseline value was also set to missing. The values are presented as proportion of positive area over total area.

A percutaneous liver biopsy was obtained at the screening visit and at Week 52. A new liver biopsy at the screening visit was not taken in the event that a previous liver biopsy taken within 120 days of the Baseline /Day 1 visit (day of first dose), and the tissue block was available. Morphometric analysis was performed using specimens stained with Sirius red and computerized image analysis. Sirius red was used to stain extracellular collagen in liver sections. Change from Baseline was calculated as the post Baseline assessment minus the Baseline assessment for a given parameter. If either the Baseline or on-treatment value was missing, the change from Baseline value was also set to missing. The values are presented as proportion of positive area over total area.

In ranked assessment (fibrosis and necroinflammation), available slides from each participant were evaluated as to whether one slide presents a globally more benign histopathology or whether the matched slides comprise globally equivalent histologic patterns. Subsequent data analysis revealed whether slides scored (within matched pairs of slides) as more benign occurred in different proportions of the Week 52 liver biopsies, according to treatment group. The number of participants with paired biopsies was based on the number with a Rank Assessment.

FibroTest was for the assessment of fibrosis. Fibro test was calculated using an original combination of five highly concentrated serum biochemical markers; alpha-2-macroglobulin, haptoglobin, apolipoprotein A1, total bilirubin and gammaglutamyltransferase. FibroTest scores range from 0.00 to 1.00 where 0.0-0.21 is no fibrosis and >= 0.59 is cirrhosis. Acti-test was calculated using 6 serum biochemical markers; alpha2macroglobulin, haptoglobin, apolipoprotein A1, total bilirubin, GGT and alanine aminotransferase. ActiTest was used for the assessment of necroinflammatory activity. Test score ranges from 0.00 to 1.00, where 0.00-0.17 indicates no necrosis and >= 0.61 indicates severe necrosis. Day 1 value was considered to be as Baseline value. Change from Baseline was calculated as the post Baseline assessment minus the Baseline assessment for a given parameter. If either the Baseline or on-treatment value was missing, the change from Baseline value was also set to missing.

- Complete abstinence from intercourse from 2 weeks prior to administration of
the study drug, throughout the study, and for a time interval after
completion or premature discontinuation from the study to account for
elimination of the investigational drug, (a minimum of 5 half-lives or

cardiovascular disease that in the investigator's opinion may adversely impact the
safety of the subject during the conduct of the study. Evidence suggestive of
cardiovascular disease may come from a number of sources, including clinical history,
physical exam, electrocardiogram, laboratory testing, and radiographic procedures.

- Documented evidence of a hepatic mass lesion suspicious for hepatocellular carcinoma.
- Alpha-fetoprotein > 200ng/mL at pre-screening.
- Inadequate hematologic function defined by any of the following:
Hemoglobin (<12.5 g/dL for men)(<12.0 g/dL for women)
Absolute Neutrophil Count (ANC) (<1.0 x 10^9/L) Platelets (<130X/10^9/L)

Summary
Brief summary
The purpose of this study is to examine the safety and effectiveness of GI262570 compared to
placebo (a pill that looks exactly like GI262570 but contains no active medicine) in
improving specific tests that indicate the degree of liver fibrosis (scarring). Subjects who
are enrolled in the study must have had prior treatment with interferon (either pegylated or
standard interferon) plus ribavirin for at least 12 weeks to treat their hepatitis C, but
either failed to clear the virus or didn't tolerate the treatment.
