About this study

Official title: A Single-arm Phase II Study of Circulating Soluble Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2) as Predictor of Benefit From Bevacizumab (Bev) Beyond Progression in Metastatic Colorectal Cancer (mCRC) - the CIRCUS Study

A growing amount of reports has consistently evidenced that a sustained inhibition of the angiogenesis is an effective therapeutic strategy, able to improve the outcome of metastatic colorectal cancer (mCRC) patients.

In the last decade different biologic agents targeting angiogenesis have been approved for the treatment of mCRC, such as bevacizumab, aflibercept and regorafenib, and, more recently, solid evidences have demonstrated the efficacy of a sustained antiangiogenic approach even beyond the first progression to a bevacizumab-containing regimen. In particular, two phase III randomized trials proved the effectiveness of prosecuting bevacizumab in second-line switching the chemotherapeutic regimen in patients already treated with bevacizumab in first-line. Preliminary experiences evidenced that circulating levels of angiogenesis-related markers are significantly modulated during first-line chemotherapy plus bevacizumab. In particular, a wide variability of plasma soluble Vascular Endothelial Growth Factor Receptor-2 (VEGFR-2) levels is observed at the time of disease progression and retrospective data suggest that benefit from the continuation of bevacizumab may be restricted to patients with high levels of soluble VEGFR-2 at the first evidence of disease progression. This study aims at prospectively validating those retrospective data.

Questions about this trial

What is this clinical trial studying?

An observational study of Metastatic Colorectal Cancer, run by Azienda Ospedaliero, Universitaria Pisana at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

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?

Progression Free Survival (time frame: from treatment start until disease progression, according to RECIST 1.1, or death due to any cause, whichever occurs first, up to 12 months after last patient last visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 Dec 2017.
