Primary | Feasibility of ctDNA analysis for RAS mutation analysis | Feasibility measures
Identification of wildtype or mutated status and results delivered to clinicians Initial clinical test results i.e. ctDNA mutations or wildtype status within 7 days Detailed mutation type characterization is provided retrospectively. Failure parameters Quality of samples; PB > 5%, CPP1 major loss < 10% Transportation > 3 week days Analysis > 3 working days Total results delivered > 7 days. |
maximum 7 days | |
Secondary | Retrospective concordance analysis | Retrospective comparison of tumor mutation and plasma mutation analysis at baseline | By end of study, expected after 3 years | |
Secondary | Disease control rate | Rate of disease control | 1 year | |
Secondary | OS | Overall survival rate | 3 years | |
Secondary | Resistance mutations | Rate of Ectoderm mutations at time of progression | At time of progression, data analysis expected after 3 years | |
Secondary | Lead time | Calcualted lead time between radiologically detected progression and molecular biologically detected ( by Ectoderm and other resistance mutations) in the ctDNA. | At time of progression, data analysis expected after 3 years |
