COPERNIC is an international, multicentre, single-arm study. Chemo-refractory mCRC subjects who meet all eligibility criteria will be treated with standard systemic chemotherapy (the decision about the treatment regimen being made by the treating physician) and undergo tumour assessment by standard imaging (either CT scan or MRI scan) at baseline and every 8 or 12 weeks until evidence of tumour progression. Response to treatment will be assessed by the local investigators according to the RECIST criteria version 1.1. Blinded, independent central review of the imaging scan will be carried out, this having no impact on treatment decisions thatwhich will remain the prerogative of the treating physician.
Serial blood samples from study subjects will be collected at pre-defined time points for ctDNA testing. Also, archived tumour tissue from each subject will be collected. Prospective and retrospective ctDNA analyses on blood samples will be carried out, and dynamics of ctDNA will be correlated with treatment outcomes prognosis.

COPERNIC is an international, multicentre, single-arm study. Chemo-refractory mCRC subjects who meet all eligibility criteria will be treated with standard systemic chemotherapy (the decision about the treatment regimen being made by the treating physician) and undergo tumour assessment by standard imaging (either CT scan or MRI scan) at baseline and every 8 or 12 weeks until evidence of tumour progression. Response to treatment will be assessed by the local investigators according to the RECIST criteria version 1.1. Blinded, independent central review of the imaging scan will be carried out, this having no impact on treatment decisions which will remain the prerogative of the treating physician.
Serial blood samples from study subjects will be collected at pre-defined time points for ctDNA testing. Also, archived tumour tissue from each subject will be collected. Prospective and retrospective ctDNA analyses on blood samples will be carried out, and dynamics of ctDNA will be correlated with prognosis.
Two ctDNA assays will be used in this study:
- FoundationOne Liquid CDx (F1LCDx) for comprehensive genomic profile (CGP) assessment
- FoundationOne®Tracker for monitoring purpose
Time points for blood samples collection:
For subjects receiving treatments with a 2- or 4-weekly schedule, blood samples for ctDNA testing will be collected at the following timepoints:
- Before treatment start (day 1)
- 2 weeks after treatment start (day 15)
- 4 weeks after treatment start (day 29)
- 8 or 12 weeks after treatment start and every 8 or 12 weeks thereafter (i.e., at the same time of each imaging tumour assessment)
For subjects receiving treatments with a 3-weekly schedule, blood samples for ctDNA testing will be collected at the following timepoints:
- Before treatment start (day 1)
- 3 weeks after treatment start (day 22)
- 6 weeks after treatment start (day 43)
- 8 or 12 weeks after treatment start and every 8 or 12 weeks thereafter (i.e., at the same time of each imaging tumour assessment)
ctDNA analyses will be done in a centralised laboratory (Foundation Medicine Inc). Full report of the ctDNA analysis will be provided to the study team to allow correlation with clinical data and exploratory analyses. The results of the ctDNA analysis will not be communicated to the treating physician (with the only exception of the analysis by F1CDx on tumour tissue at screening) and therefore will not have any impact on treatment decision (i.e., all study subjects will be treated according to standard practice).

|
- Optimal timepoint and cut-off value for early on-treatment ctDNA changes [ Time Frame: Day 15 or 22 ]To select the optimal timepoint and cut-off value for early on-treatment ctDNA changes (as assessed by F1LCDx and FoundationOne®Tracker and F1LCDx) that predict progressive disease as best radiological response with a high degree of specificity.
- optimal timepoint and cut-off value for on-treatment ctDNA changes at 4 or 6 weeks [ Time Frame: Day 29 or 43 ]To select the optimal timepoint and cut-off value for on-treatment ctDNA changes at 4 or 6 weeks (as assessed by FoundationOne®Tracker) that predict progressive disease as best radiological response with a high degree of specificity.
- rapid turnaround time of ctDNA testing based on F1LCDx [ Time Frame: through study completion, an average of 1 year ]To demonstrate rapid turnaround time of ctDNA testing based on F1LCDx and identify technical or logistical challenges to the implementation of an on-treatment ctDNA-driven treatment approach in a follow-on study.
- tumour heterogeneity [ Time Frame: Day 1 ]To evaluate tumour heterogeneity before treatment start as assessed by F1CDx in the tumour tissue and F1LCDx in the whole blood.
- CGP changes during treatment [ Time Frame: Day 1 and 15 or D1 and D22 ]To track CGP changes during treatment as assessed by F1LCDx.
- exploratory genomics and radiomics profiles associated with progresdsive disease as best radiological response [ Time Frame: through study completion, an average of 1 year ]To characterize the positive predictive value of baseline genomic and radiomic profiles for tumour progression at the first radiological assessment
- prognostic value of ctDNA. [ Time Frame: through study completion, an average of 1 year ]To confirm the prognostic value of ctDNA.
