Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: This prospective study will enroll 50 subjects with radiologic confirmation of recurrence of colorectal cancer and 50 subjects without CRC recurrence (documented by CT scan). Eligible study subjects will include men and women (18 years or older) of any race and ethnicity who have completed treatment (no further adjuvant chemotherapy or surgery currently planned) for primary CRC of stages II and III (AJCC, [2]), and have been considered by the site clinical management team for at least 6 months to be in remission. . (Concurrent imaging is not required as part of the clinical determination of remission. Subjects who have had a recent (within 4 weeks) or prior CT scan for purposes of surveillance are eligible.)

Who may be able to join

  • Subject is 18 years or older, and capable and willing to provide informed consent.
  • Subject has undergone curative treatment for primary CRC of stages II and III (AJCC).
  • Subject was determined to be in remission at the conclusion of primary therapy and has been in clinical surveillance for at least 6 months. (No imaging is required for the determination of remission. Last treatment was at least 6 months earlier. No requirement to complete all of the initial adjuvant treatment plan.)
  • Subject has had a surveillance CT scan within the past 4 weeks and either has recurrent CRC or does not have recurrent CRC based on that CT scan result.
  • Subject is willing to provide a blood sample. (2 PAXgene tubes)
  • Definition of recurrence is evidence of local tumor recurrence or metastasis by CT scan of chest, abdomen and pelvis or other modalities that confirm recurrent CRC

Who cannot join

  • Subject has other cancer at the time of recruitment.
  • Subject has prior history of recurrent CRC.
  • Subject has a diagnosis of End Stage Renal Disease (ESRD), with or without current dialysis treatment.
  • Subject's life expectancy is less than one year based on performance status and clinical signs and symptoms.
  • Subject is receiving chemo- or radiotherapy at the time of blood collection, or between radiological imaging and blood collection.
  • Results of the recent surveillance CT of the chest, abdomen and pelvis are inconclusive regarding recurrence of CRC, and further work up (other imaging and/or biopsy) is not required at this time.

About this study

Official title: Evaluation of the Performance and Sensitivity of the Clinical Genomics Colvera Test in Predicting Recurrence of Colorectal Cancer

To compare the sensitivity and specificity estimates of Colvera with that of a commercially available CEA test for detection of recurrent disease in subjects with colorectal cancer that have documented recurrence or no evidence of recurrence by CT.

Read the detailed description

The study will be carried out as a single cohort, observational, prospective study to compare sensitivity of Colvera to detect recurrent colorectal cancer confirmed by radiology imaging (CT) with CEA sensitivity in paired testing. Blood is collected for assay of methylated BCAT1 and IKZF1 DNA and CEA, from subjects who have undergone curative treatment for primary CRC of stages II and III (AJCC) and who are in remission (No evidence of disease). Subjects will have recently (within 4 weeks of blood collection) had follow-up radiological imaging as part of their surveillance program for recurrence. Participation is for one visit only as part of each subject's surveillance-monitoring schedule. Two PAXgene blood tubes (minimum 10 mL, maximum 20 mL) will be collected. Any evidence of methylated BCAT1 and/or IKZF1 DNA in blood represents a Colvera "positive" result. CEA levels of 5ug/L or higher will represent a "positive" result. Sensitivity and specificity of the Colvera and CEA test will be estimated and compared in a paired fashion in each case where recurrence status has been investigated and determined by the site clinical management team. Blood testing shall be performed and analyzed by qualified staff blinded to clinical status. This is a cross-sectional observational non-significant risk study, and test results will not be used for clinical management, i.e. there will be no interventions in subjects consenting to participate in this Research Study.

No recurrenceCT scan has confirmed that subjects are without recurrence. Blood can be drawn up to 4 weeks after scan. Effective Feb 28, 2019, this group is closed to accrual as it has reached the goal.

RecurrenceCT scan has confirmed that subjects are have recurrence of their colorectal cancer. Blood can be drawn prior to any treatment for the recurrent disease.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer, run by Clinical Genomics Pathology at 6 sites in United States.

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 6 inclusion and 6 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 13 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. 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?

Sensitivity, specificity, positive predictive value and negative predictive value (time frame: 1 year). 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 13 Feb 2020.
