Exact Sciences Mourns the Death of Dr. David Ahlquist, a Pioneer in Early Cancer Detection


Unwavering. That’s how we think of our chief scientific advisor, Dr. David Ahlquist. With deep sorrow, we announce Dr. Ahlquist’s untimely passing yesterday at the age of 69, one year after being diagnosed with amyotrophic lateral sclerosis (ALS).

In February 2009, Exact Sciences’ board of directors began searching for a new team to develop a non-invasive colorectal cancer screening test. As part of that search, the board asked Kevin Conroy and Maneesh Arora to meet with Dr. Ahlquist and his team of researchers at Mayo Clinic. During that meeting, Dr. Ahlquist detailed his vision for what became Cologuard® and a bold future where a simple blood test could be used to screen for most types of cancers. Dr. Ahlquist’s incredible vision in that meeting helped spark a revolution in cancer screening.

Exact Sciences’ very existence is largely because of Dr. Ahlquist’s passion for defeating cancer through early detection, one he pursued with brilliance and a determination to make life better for others. Despite his ALS challenges, Dave, as he preferred to be called, never stopped providing invaluable scientific leadership to our scientists and leadership team. As recently as last Friday, Dave joined our weekly scientific team’s meeting, prodding the team to think about new ways to help save lives through innovative cancer diagnostics.

Dave was a gastroenterologist and served patients at Mayo Clinic for 36 years. Along with Dr. Graham Lidgard, our chief science officer, and others, he is a co-inventor of Cologuard, a test that has screened more than 4.5 million people for colorectal cancer.

Dave was a renowned teacher, scientist, researcher, inventor, mentor, and amateur author. He was also a passionate outdoorsman, naturalist, and cross-country skier. Dave was humble and kind, and he was relentlessly optimistic about the future. Despite his professional successes, the titles that mattered most to Dave were husband, father, grandfather, and friend.

“I could live a hundred lives and not meet as amazing of a person as Dave. He pushed us to dream big dreams, with his oft-repeated calls to arms: ‘Hard is not an excuse for not trying,’ and ‘If we can, we must.’ It’s hard to imagine a world without Dave in it, and the whole team at Exact Sciences is broken-hearted. Our Exact Sciences team promised Dave that we would continue the work to defeat cancer through early detection with his same unwavering commitment to advancing our science to benefit the maximum number of people,” said Kevin Conroy, chairman and CEO.

The Exact Sciences team thanks Dave for his friendship and will seek to honor him by focusing on bringing to patients a test that will change the way people all over the world get screened for cancer.

The Exact Sciences team offers deepest sympathies to his loving wife, Susan, and his children Aaron (Elizabeth), Daniel (Amanda), Brooke (Bryant Carlson), and his 7 grandchildren. May his memory be a blessing.

About Cologuard
Cologuard was approved by the FDA in August 2014, and results from Exact Sciences' prospective 90-site, point-in-time, 10,000-patient pivotal trial in adults 50 years of age or older were published in the New England Journal of Medicine in March 2014. Cologuard is included in the American Cancer Society's (2018) colorectal cancer screening guidelines and the recommendations of the U.S. Preventive Services Task Force (2016) and National Comprehensive Cancer Network (2016). Cologuard is indicated to screen adults 45 years of age and older who are at average risk for colorectal cancer by detecting certain DNA markers and blood in the stool. Do not use Cologuard if you have had precancer, have inflammatory bowel disease and certain hereditary syndromes, or have a personal or family history of colorectal cancer. Cologuard is not a replacement for colonoscopy in high risk patients. Cologuard performance in adults ages 45-49 is estimated based on a large clinical study of patients 50 and older. Cologuard performance in repeat testing has not been evaluated.

The Cologuard test result should be interpreted with caution. A positive test result does not confirm the presence of cancer. Patients with a positive test result should be referred for diagnostic colonoscopy. A negative test result does not confirm the absence of cancer. Patients with a negative test result should discuss with their doctor when they need to be tested again.

Medicare and most major insurers cover Cologuard. For more information about Cologuard, visit www.cologuardtest.com. Rx Only.
