E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Roche Sample Repository Research Project:
Included in the protocol Version 2.0, dated 2009-03-09.
Patient Information Sheet/Informed Consent Form dated 2009-02-11
Investigation of Prognostic/predictive markers – VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGFR1 (FLT1),
VEGFR2 (FLK/KDR), VEGFR3 (FLT4), PDGFR-alfa, PDGFR-beta, VHF, HIF-alfa, Neuropilin-1/2, and
KRAS.
The purpose of investigating these prognostic/predictive markers is to identify molecular markers with
prognostic/predictive value on clinical endpoints such as e.g. response or overall survival. The focus will be
on pharmacogenetics of bevacizumab, since so far no molecular parameters are established for predicting
bevacizumab efficacy and toxicity. Therefore expression of VEGF and its receptors as well as selected genes of
the VEGF-pathway will be determined and genetic data will be analyzed with respect to expression profile and
clinical outcome.
This investigation is optional for each patient and is therefore subject to a separate informed consent. All
samples will be pseudonymized by using a numeric code as it is done in the main study. All samples and
remains of samples taken for this investigation will be destroyed 2 years after the end of the main study at the
latest.
