About this study

Prometheus's Onco dX assay platform provides technological breakthrough for immunoassay by obtaining a level of sensitivity down to single tumor cells without compromising specificity. This allows assessment of multiple TKI treatment targets, their activation status, as well as down stream signaling proteins using very tiny amount of tissue that can be obtained by FNA or CTCs.

We planned this study to explore biomarkers predictive of clinical response to cetuximab-based treatment in metastatic colorectal cancer using the Prometheus Platform. We will also elucidate signal transduction pathway attributable to cetuximab resistance, monitor changes in the RTK activation status during cetuximab treatment using circulating tumor cells and analyze correlation between the quantity of circulating tumor cells and treatment response to cetuximab.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To explore biomarkers predictive of clinical response to cetuximab-based treatment in metastatic colorectal cancer using the Prometheus Platform

    1. To analyze expression and activation status of receptor tyrosine kinases in signal transduction pathways in FNA samples and circulating tumor cells B. To identify negative predictive markers to cetuximab

    Measured: at Screening (Day - 21 ~ 0 ), at 4 weeks and average 6months(end of treatment)

Secondary outcomes (3)
  1. 1. RTK activation status during cetuximab treatment using circulating tumor cells

    Measured: at Screening (Day - 21 ~ 0 ), at 4 weeks and average 6months(end of treatment)

  2. 2. signal transduction pathway attributable to cetuximab resistance

    Measured: at Screening (Day - 21 ~ 0 ), at 4 weeks and EOT (end of treatment)

  3. 3. To analyze correlation between the quantity of circulating tumor cells and treatment response to cetuximab

    Measured: at Screening (Day - 21 ~ 0 ), at 4 weeks and average 6months (end of treatment)

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer, run by Samsung Medical Center at 1 site in South Korea.

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 7 inclusion and 5 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 23 Feb 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 South Korea. 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?

To explore biomarkers predictive of clinical response to cetuximab-based treatment in metastatic colorectal cancer using the Prometheus Platform (time frame: at Screening (Day - 21 ~ 0 ), at 4 weeks and average 6months(end of treatment)). 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 23 Feb 2017.
