About this study
Pathway Genomics Corporation (Pathway Genomics), a San Diego, California company, is involved in the development and validation of new molecular diagnostic assays for the analysis of circulating tumor deoxyribonucleic acid (DNA) (ctDNA) found in the plasma-derived DNA (cell-free DNA or cfDNA) in order to identify specific variants (mutations) in cancer driver genes. The purpose of testing for mutations in ctDNA is to detect and monitor cancer. All cells shed DNA into the bloodstream. Finding cancer-associated mutations in the cfDNA may lead to early detection of cancer in an otherwise apparently healthy (i.e. asymptomatic) individual or may allow the healthcare provider to more effectively monitor and treat a known cancer patient. The analysis is performed using a polymerase chain reaction (PCR)-based methodology where oligonucleotides are designed to target specific mutations in designated genes of interest followed by next generation deep sequencing of the amplified targets. Evaluation of the performance of these assays for screening for cancer in asymptomatic subjects is essential for the clinical validation of the use of these assays. The specific aim of this protocol is to obtain relevant human blood samples from individual subjects at higher than average risk for the development of cancer due to age, heredity, or environmental or toxic exposures for use in the statistical analysis of this method as an adjunct screening test for the potential presence of cancer.
Read the detailed description
The objectives of this study are to obtain human blood samples from asymptomatic subjects who have never been diagnosed with cancer, but who may be at increased risk for cancer due to heredity, exposures, age, or family history to assess the validity of screening healthy but at risk patients for cancer via analysis of ctDNA.
Specifically, the blood specimens will be collected from individuals who have responded to a self-administered health questionnaire that screens for higher risk of contracting cancer. Each participant will be asked to provide a 30 ml blood sample to be drawn by a primary care provider (PCP) or licensed phlebotomist. The specimens collected during the study may also be used in the research and development of new or modified molecular genetics assays. The results of these studies will be used to further the understanding of the use of ctDNA for the detection and monitoring of cancer in humans.
The blood samples are collected in blood collection tubes (BCT) called Cell-Free DNA BCT® manufactured by Streck and intended for collection, stabilization and transportation of cell-free plasma DNA. This device also stabilizes and preserves cellular genomic DNA present in nucleated blood cells and circulating epithelial cells (tumor cells) found in whole blood. This product has not been cleared by the U.S. Food and Drug Administration for In Vitro Diagnostic use and is labeled by Streck for research use only. Under the Clinical Laboratory Improvement Amendments (CLIA) regulations, laboratories are authorized to validate and use, as part of a laboratory-developed test (LDT), devices that have not been cleared or approved by the FDA. Pathway Genomics validated the CancerInterceptTM Detect molecular analysis system with the Streck tubes, in accordance with CLIA.
Once the specimen has been collected and sent to Pathway by the physician or the phlebotomist who collects the samples, all other processing and testing are conducted by Pathway laboratory personnel. The analysis begins with the separation of the plasma from the rest of the blood sample. cfDNA will then be isolated from each sample. The quantity of cfDNA is measured and then the sample is amplified via PCR for next generation sequencing. The results of the sequencing will then be analyzed for the presence of one or more of the 96 mutations analyzed in this assay. The data are then reviewed and a report will be generated.

ctDNA Analysis for the Detection of Genetic MutationsGenetic
Cell-free DNA (cfDNA) is isolated from a blood plasma sample and tested for the presence of 96 specific well-described mutations in 9 cancer driver genes. The presence of more than 2 copies of a mutation may indicate the presence of a malignancy. Follow up with the subject's physician would be needed for an examination and any additional testing that the physician wants to perform to further assess for the development of cancer.
| Study group | Role | What they receive |
|---|---|---|
| Increased Risk for Cancer Development | The group is to include at least 1000 individuals who are at high risk for the development of cancer. Risk is assessed through the completion of a clinical history questionnaire. Examples of such subjects include those with known hereditary cancer syndrome pathogenic variants without a diagnosis of cancer, with significant family history of breast, ovarian, colon, or lung cancer or melanoma, or another strong history of cancer but no prior molecular diagnosis, heavy smokers or those exposed to carcinogens and mutagens. The individuals who meet criteria for inclusion will undergo cell-free DNA isolation and circulating-tumor DNA (ctDNA) analysis for the detection of genetic mutations associated with the possible development of a malignancy. Receives: Genetic: ctDNA Analysis for the Detection of Genetic Mutations |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of subjects found with one or more of 96 ctDNA mutations
A cohort of 1000 or more individuals who are at high risk for the development of cancer will be tested for the presence of 96 well-described mutations in 9 cancer driver genes via ctDNA analysis. The number of individuals with one or more of the 96 assayed mutations will be assessed.
Measured: 1 year
Number of copies of mutant alleles found in the positive subjects
Among the cohort of subjects enrolled in the study in whom one or more of the 96 ctDNA mutations are detected, the number of copies per analyzed plasma sample will be calculated.
Measured: 1 year
Percentage of ctDNA found within the total amount of circulating free DNA (cfDNA)
Within the samples found to contain one or more ctDNA mutation, the percentage of ctDNA within the total amount of cfDNA will be calculated.
Measured: 1 year
Secondary outcomes (1)
Number of subjects with one or more of 96 ctDNA mutations who develop cancer
The 1000 or more individuals in the study will be followed for 1 to 5 years to assess for the development of a malignancy. Special attention will be paid to the cohort who have initial assays indicating the presence of ctDNA. The subjects may be retested over time to show changing levels of ctDNA. Their own physicians will guide any follow up studies such as imaging or other laboratory testing. The test is designed as a means of case finding for cancer among individuals with high risk for development of cancer.
Measured: 1 to 5 years

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Pathway Genomics Corporation (Pathway Genomics), a San Diego, California company, is involved in the development and validation of new molecular diagnostic assays for the analysis of circulating tumor deoxyribonucleic acid (DNA) (ctDNA) found in the plasma-derived DNA (cell-free DNA or cfDNA) in order to identify specific variants (mutations) in cancer driver genes. The purpose of testing for mutations in ctDNA is to detect and monitor cancer. All cells shed DNA into the bloodstream. Finding cancer-associated mutations in the cfDNA may lead to early detection of cancer in an otherwise apparently healthy (i.e. asymptomatic) individual or may allow the healthcare provider to more effectively monitor and treat a known cancer patient.

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?
Number of subjects found with one or more of 96 ctDNA mutations (time frame: 1 year). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02612350, which also lists 17 linked publications.
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 6 Apr 2018.
