A Non-Interventional Follow-Up to the VELOUR Study - Translational Research
A Non-Interventional Follow-Up to the VELOUR Study (Multicentre International Study of Aflibercept Versus Placebo in Combination With FOLFIRI for Metastatic Colorectal Cancer) - Translational Research
This is a follow-on study to the VELOUR trial (NCT00561470). The aim of this study is to acquire the archived colorectal cancer and metastasized tissue tumour blocks of patients who have participated in the VELOUR study.
These samples will be analysed to find proteins or markers which represent how an individual may be responding to treatment. The identification of these markers may help provide personalised and more effective treatment programs for patients with similar conditions in the future.

Gedetailleerde beschrijving
The VELOUR trial (NCT00561470) has demonstrated the efficacy of aflibercept as a second line treatment in combination with fluorouracil, leucovorin, irinotecan (FOLFIRI)for metastatic colorectal cancer (mCRC) patients refractory to a first line oxaliplatin based chemotherapy regimen (Van Cutsem E., JCO 30 (2012):pp3499-3506). The FDA has approved Aflibercept (Zaltrap) for the treatment of metastatic colorectal cancer in combination with FOLFIRI on August 3rd 2012 and by European Medical Agency (EMEA) on November 15th 2012.
While the VELOUR study confirmed the benefits of using aflibercept in combination with FOLFIRI, the availability of biomarkers accurately predicting patients responding to this combination would further improve clinical utility of this drug. The molecular profiling of the Formaldehyde fixed paraffin embedded (FFPE) clinical tumor samples and serial plasma samples obtained from patients involved in VELOUR study and subsequent analysis of the molecular and clinical data would provide an invaluable opportunity to discover and potentially validate such biomarkers.
As blocks were not collected as part of the VELOUR trial, this protocol deals primarily with the steps that will be taken to gain ethics and consent in each of the participating countries and how the blocks will then be sourced and acquired, finally deposited in a biobank situated in KULeuven.
A VELOUR Translational Research Consortium (VTRC) has been formed by the Catholic University of Leuven (KULeuven)and Almac Diagnostics for the realisation of this study. The number of blocks available based on the surgical list held for the trial is estimated at 1030 (84% of complete trial cohort) and from a profiling viewpoint it has been calculated that the minimum number of blocks acceptable for processing and biomarker identification / validation is 500.
Due to the specific interest in angiogenesis, the VTRC consortium will aim to source blocks with both tumor and surrounding stromal tissue which will then be macro-dissected with the aim to generate data for both the tumor and surrounding angiogenic stroma. The project will generate gene expression, immunohistochemistry (IHC) and mutational data for these samples. In addition single nucleotide polymorphisms (SNP) data will be generated from non-tumor tissue, focusing on polymorphisms that demonstrate an association with disease or response outcome to therapy. Pre-processing and in silico evaluation of all data generated will support the outcome objectives of this study.
