About this study
Immune therapy represents a promising option for the treatment of an increasing number of malignancies. New immunotherapeutic strategies are currently under development and will be further studied starting from refractory settings of heavily pre-treated mCRC patients. On this basis, a specific immunological characterization of CRC metastasis will be relevant to direct future clinical and pharmacological research.
As surgery is a therapeutic option in the treatment of mCRC, a percentage of mCRC patients undergo to resection of metastasis before or after medical treatment. These tumour samples could be useful to define the immune signature of colorectal metastatic disease.
On the basis of the above reported considerations, an exploratory, prospective, observational study for the immunophenotypical characterization of colorectal cancer metastasis from pre-treated vs chemo-naive patients has been planned.
Read the detailed description
- There is extensive evidence for molecular heterogeneity in CRC. Studies have revealed that intra-tumour heterogeneity can be highly variable within primary tumours or between primary and metastatic sites (1). Moreover, tumour heterogeneity can be linked to targeted therapies in terms of acquired resistance mutations (2). In the era of precision medicine, specific molecular characterization of primary tumour and metastasis taking into account the dynamism of the disease and the actual therapeutic target should be considered.
- Nowadays there is not enough information regarding the immunological characterization of CRC metastasis. Especially, few data are available about the effect of chemotherapy and targeted drugs on the interplay between tumour and the immune system of the host (3).
- Immune system takes part to different phases of tumour growth (4). It is a dynamic balance that can be differentially modulated by several agents, resulting in immunosuppression or immunostimulation. Becht et al. integrated the molecular classification of colorectal cancer with information about their immune microenvironment. They identified 2 "immune-high subgroups". The MSI-rich CMS1 group is characterized by an immune stimulating contexture while the mesenchymal CMS4 group has an immune suppressive microenvironment (5). No data regarding the evolution over time of these features are available so far.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
immunological features of metastasis (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Nov 2020.
