Official title
A Prospective Multi-canceR Early-detection and interVENTional Study in Asymptomatic Individuals: PREVENT
Overview
PREVENT is a prospective, multicenter, interventional study evaluating the performance of the OverC multi-cancer detection blood test in asymptomatic individuals with cancer risk.
Detailed description
Participants will receive the OverC multi-cancer detection blood test along with standard-of-care screening, whose results will be returned to health care providers and participants. The diagnostic procedures will be guided firstly by the OverC multi-cancer detection blood test and then by the standard-of-care screening. The number, cancer types, and cancer clinical stage of cancer patients diagnosed via the OverC multi-cancer detection blood test will be recorded.
The study will enroll approximately 12,500 participants as defined by eligibility criteria with an anticipated enrollment period of approximately 9 months at up to 30 clinical sites within China. Participants will be actively followed for approximately 5 years from the date of their enrollment.
Interventions
- Device OverC multi-cancer detection blood test
Blood collection for the OverC multi-cancer detection blood test and standard-of-care screening with return of results
Primary outcome measures
- The cancer clinical stages of cancer patients diagnosed via the multi-cancer detection blood test [Time frame: Up to 5 years]
- Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for the multi-cancer detection test alone or with standard-of-care screening as evaluated after 1-year follow-up [Time frame: Up to 1 year]
Secondary outcome measures (4)
- Changes in health-related quality of life in individuals with a positive result of the multi-cancer detection test assessed by Short Form Health Survey (SF-12v2) [Time frame: Up to 5 years]
- Changes in anxiety as evaluated by Self-rating Anxiety Scale (SAS) of individuals with a positive result of the multi-cancer detection test [Time frame: Up to 5 years]
- Satisfaction with the multi-cancer detection test [Time frame: Up to 5 years]
- Sensitivity, specificity, PPV, and NPV for the multi-cancer detection blood test alone or with standard-of-care screening as evaluated after 3- and 5-year follow-up [Time frame: Up to 5 years]
