Criteria that we believe are essential to an impactful MCED test:

Harness the additive sensitivity of multiple biomarker classes

Detect multiple cancers, including those with the biggest impact to public health

Provide high specificity to help minimize false positive results

Deliver high sensitivity to detect more early-stage cancers, when there is a greater chance for curative intervention

Utilize a streamlined and standardized imaging-based diagnostic resolution pathway that results in fewer procedures

DETECT-A RESULTS

The CancerSEEK test, the MCED test studied in DETECT-A, was the forerunner to the MCED test currently in development.

The DETECT-A (Detecting cancers Early Through Elective mutation-based blood Collection and Testing) study was the first-ever large, prospective, interventional study to use a blood test to detect multiple types of cancer in a real-world setting. The DETECT-A study enrolled more than 10,000 women with no history of cancer to determine if a blood test in combination with standard-of-care screenings could detect cancers before signs and symptoms appeared.3

Rosemary’s story

The latest data show the potential value of a multi-biomarker class design

The complementary nature of different biomarker classes demonstrated in the DETECT-A study inspired further studies on multi-biomarker class cancer detection. Late breaking data presented at the 2024 American Association for Cancer Research (AACR) conference details the outcomes of the first analysis from the ASCEND 2 study, demonstrating that a multi-biomarker class test combining methylation and protein biomarkers delivers sensitivity and specificity needed to detect numerous cancer types even at earlier stages and confirms the value of a multi-biomarker class approach.4

Prospectively Collected Case-Control Study

The first analysis from the ASCEND 2 study, a multi-center, prospectively collected case-control study of clinically characterized patients evaluated the performance of a multi-biomarker class MCED test in 6,354 patients. Results demonstrated combining an enhanced classifier design with two high-performing biomarker classes selected for their proven ability to identify cancer earlier delivers the sensitivity and specificity needed to make a real impact on patient care.4

Continuing our rigorous approach to clinical development

The next steps in our commitment to improving and validating a novel MCED test include completion of ongoing studies to finalize the biomarker selection for the Cancerguard™ test in development while preparing to initiate a prospective, interventional, longitudinal pivotal trial.

Exact Sciences has joined forces with the broader cancer community, patient advocacy organizations, and forums—such as the MCED Consortium, BLOODPAC, and the American Cancer Society—to help to shape the future of cancer detection. Together we are working towards a shared goal to help reduce cancer’s burden on humanity.

We are growing thought leadership for the MCED field

The Cancerguard™ test is under development. The features above describe current development goals. It has not been cleared or approved by the US Food and Drug Administration or any other national regulatory authority.
