Not applicable Interventional Guangzhou Burning Rock Dx Co., Ltd. · NCT05227534

This study is testing a new blood test to see if it can help find different types of cancer early in healthy people aged 40 to 75 who are at risk.

What this trial studies

PREVENT is a multicenter interventional study that evaluates the effectiveness of the OverC multi-cancer detection blood test in asymptomatic individuals at risk for cancer. Participants aged 40 to 75 will undergo this blood test alongside standard cancer screening methods. The study aims to identify various cancer types and stages through the results of the OverC test, with approximately 12,500 participants enrolled over a 9-month period across 30 clinical sites in China. Follow-up will continue for about 5 years to monitor outcomes.

Who should consider this trial

Good fit: Ideal candidates are asymptomatic individuals aged 40 to 75 who have not undergone certain cancer screenings in the past five years.

Not a fit: Patients with existing cancer symptoms or those who have recently undergone specific cancer screenings will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection of multiple cancers, improving treatment outcomes for patients.

How similar studies have performed: Other studies have shown promise in early cancer detection using blood tests, but the specific approach of the OverC test is relatively novel.
