E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
One sub study CTC biomarker profiling will be conducted at selected sites, however Greece has not be chosen to participate in these sub-studies. The objective of the CTC biomarker profiling to assess candidate biomarkers predictive of orteronel antitumor activity including, but not limited to, the TMPRSS2:ERG fusion gene, the AR gene and the PTEN gene and the other clinical endpoints such as OS and time to disease progression. Details of the sub study is provided in the protocol C21005, dated 21st July 2010. |
