Summary
Brief summary (as posted)

- Screening to Day 1 Predose
- description
- The GFS was measured by microarray analysis using the entire 101 gene signature. The GFS is quantified as the change in gene expression between two separate samples collected from the same patient. The signature has 101 genes in two oppositely regulated arms, which are pre-specified. The expression of genes in the UP arm goes up with increasing pathway activity, and the expression of genes in the DOWN arm goes down with increasing pathway activity. The GFS variability was represented by the GFS change between two baseline samples (Mean GFS Fold Ratio \[Screening to Day 1 Predose\]).
