Early Cancer Detection Test EarlyCDT®

The Early detection of Cancer of the Lung Scotland (ECLS) trial conducted in Scotland with 12,208 patients, is believed to be the largest randomized controlled trial using blood biomarkers for the detection of lung cancer.

Results demonstrate the potential of the EarlyCDT Lung blood test to reduce the incidence of patients with late-stage lung cancer at diagnosis, compared with standard clinical diagnosis.

In a randomized controlled trial of 12,208 people in Scotland at high risk of developing lung cancer, it was shown that more people were diagnosed at an early stage of the disease in the two years after having the EarlyCDT Lung blood test than those in the control arm who received standard clinical care.

The findings, presented at the 2019 World Conference on Lung Cancer hosted by the International Association for the Study of Lung Cancer (IASLC) in Barcelona, are an important validation of EarlyCDT’s diagnostic platform technology which harnesses the power of the immune system, to detect evidence of the body’s natural response to cancer. The technology can detect cancer on average four years before standard clinical diagnosis.

Lung cancer was chosen as the first target of the technology because it is the world’s leading cause of cancer-related death and is often detected at an advanced stage with approximately 85% of patients in the UK undiagnosed until the disease has spread to other parts of the body.

Among those people who received the EarlyCDT Lung test and went on to develop lung cancer within the next two years, 41.1% were diagnosed at an early stage (stage 1&2) of the disease, compared with 26.8% among the control group subject to standard clinical practice. This resulted in a 36% reduction in late-stage presentation after 2 years of follow up in subjects randomized to the EarlyCDT blood test.

The trial also showed a lower rate of deaths among people in the intervention arm of the trial after two years compared with people in the control group. Lung cancer-specific deaths were also lower in the intervention group. This suggests that the EarlyCDT Lung blood test followed by CT imaging could produce a mortality benefit, although the trial was not powered to demonstrate such a trend after two years.

The results further validate the use of EarlyCDT’s platform technology as a screening modality, which can detect cancer four years or more before standard clinical diagnosis. The patented technology works by detecting the presence of autoantibodies generated by the body’s immune system as a natural defence against cancer cells.
