There’s evidence that a cancer drug can cut deaths from lung cancer by as much as 50% when pathology testing indicates the patient has the EGFR mutation
Results from a decade-long clinical trial indicate that lung cancer patients with the epidermal growth factor receptor (EGFR) mutation have significantly better survival rates when treated with the drug osimertinib. This is a positive step forward for precision medicine and will give clinical laboratories an opportunity to deliver more value to physicians and patients.
The study known as ADAURA was led by scientists at Yale University and funded by British pharmaceutical/biotechnology company AstraZeneca. The researchers recently found that taking the cancer drug osimertinib (brand name Tagrisso) reduces by half the number of deaths among patients who had undergone surgery for EGFR–mutated, stage IB to IIIA non-small-cell lung cancer (NSCLC), according to NBC News.
Lung cancer has been one of the toughest types of cancers to diagnose early. When finally diagnosed, many patients do not have a good prognosis. Thus, the results of this multi-national study—and the connection involving patients with the EGFR gene—is a welcome development that promises better outcomes for cancer patients.
At the same time, this increases the value of EGFR as a biomarker for clinical laboratories and pathology groups that offer EGFR testing. It could become a companion diagnostic test—part of a clinical guideline for diagnosing lung cancer—that helps identify appropriate anti-cancer drugs for specific patients.
The researchers published their findings in the New England Journal of Medicine (NEJM) titled, “Overall Survival with Osimertinib in Resected EGFR-Mutated NSCLC.” They also presented the results of their study at the American Society for Clinical Oncology (ASCO) conference.
“Adjuvant osimertinib is currently the only EGFR tyrosine kinase inhibitor to translate a statistically significant and practice-changing disease-free survival benefit into a significant [overall survival] benefit in a phase 3 trial, supporting osimertinib as the standard of care for patients in this setting,” said Roy Herbst, MD, PhD, Deputy Director and Chief of Medical Oncology at Yale Cancer Center, who led the Yale study, at the 2023 ASCO Annual Meeting, according to an ASCO news release.

Identifying Best Candidates for Specific Cancer Drugs
The results of the Yale-led study of the cancer drug osimertinib suggest that testing for a mutation in the EGFR gene could become part of the standard-of-care for NSCLC. Researchers found that NSCLC patients with the mutation showed improved survival rates and reduced risk of recurrence when taking the drug following surgery. EGFR tests could thus become companion diagnostics to determine whether patients are good candidates for the drug.
“We have been using one-size-fits-all adjuvant chemotherapy for every patient with lung cancer despite a decade of advances in targeted treatments for select groups of patients that result in dramatically better outcomes,” Nathan Pennell, MD, PhD, Vice Chair of Clinical Research and Director, Lung Cancer Medical Oncology Program Cleveland Clinic Taussig Cancer Institute, told the ASCO Post.
Pennell, who was not involved in the Yale research, described the finding as “a first for the lung cancer field,” and said adjuvant osimertinib “should be the new standard of care” for patients with EGFR-mutated NSCLC.
‘Practice-changing’ Cancer Drug
The study was led by Roy S. Herbst, MD, PhD, Deputy Director and Chief of Medical Oncology at Yale Cancer Center and Assistant Dean for Translational Research at Yale School of Medicine. Herbst is the principal investigator for the ADAURA global multi-site clinical trial which enrolled 682 patients with stage IB-IIIA NSCLC, in an effort to determine the efficacy of the cancer drug osimertinib, a pill taken once a day, which, according to NBC News, has fewer major side effects than chemotherapy.
The FDA approved the drug in 2015 for patients with advanced lung cancer. In 2020, the agency approved its use at earlier stages of the disease.
The ADAURA study included patients from 26 countries across Europe, North America, South America, and the Asia-Pacific region. About half of the patients took the pill each day for three years following surgery. The other half received a placebo.
According to a Yale news release, the researchers reported that 88% of patients treated with the drug were still alive five years later, compared with 78% of patients who received the placebo.
Earlier research demonstrated that the drug prevented recurrence of tumors and kept the disease from spreading to other organs, NBC News reported. “However, what we are seeing now is that patients will also live longer,” said oncologist Charu Aggarwal, MD, MPH, of the University of Pennsylvania’s Perelman School of Medicine, who was not involved in the study.
Herbst described the drug as “practice-changing” in the Yale news story.
An EGFR ‘Off Switch’
Non-small cell lung cancer is the most common form of lung cancer, The Guardian reported, adding that the EGFR mutation “is found in about a quarter of global lung cancer cases, and accounts for as many as 40% of cases in Asia. An EGFR mutation is more common in women than men and in people who have never smoked or have been light smokers.”
The mutation can cause cells to “excessively divide and multiply, which may cause cancer,” NBC News explained. Herbst described osimertinib as an “off” switch for the mutation.
“I think we’re curing some patients,” he said at the ASCO annual meeting, NBC News reported. “We’re really showing progress in lung cancer like never before,” he noted, adding that the results were “about twice as good as we expected.
“Overall survival has historically been considered the gold standard efficacy endpoint for randomized adjuvant clinical trials. The results of the ADAURA trial will broaden treatment access for patients with EGFR-mutated NSCLC,” Herbst told ASCO Post. “Together with the practice-changing disease-free survival data from our primary analysis, the overall survival benefit instills confidence that adjuvant osimertinib is the standard of care for patients with resected EGFR-mutated stage IB to IIIA NSCLC.”
Side effects of the pill include skin rashes and mild diarrhea, but in general the drug is “quite well tolerated,” Herbst said.
Impact on Labs
In Herbst’s view, the results of the Yale study demonstrate that patients diagnosed with lung cancer should be tested for the EGFR mutation, which is not always the case, The Guardian reported. “This further reinforces the need to identify these patients with available biomarkers at the time of diagnosis and before treatment begins,” he said.
Aggarwal agreed, telling NBC News that data from the study could be a “call to action” for more EGFR screening.
In light of the results, clinical laboratories and anatomic pathology groups should expect that EGFR screening may soon become a companion diagnostic test as part of a precision medicine clinical guideline for early diagnosing of lung cancer.

Executive War College Headliners Connect Genetic Testing, Wearable Technology, Precision Medicine, and Struggle Over Claim Reimbursement between Clinical Labs and Payers
Keynote speakers advise clinical laboratory leaders to leverage diagnostic data that feeds precision therapies
At this week’s Executive War College on Diagnostics, Clinical Laboratory, and Pathology Management in New Orleans, keynote presenters dissected ways that clinical laboratory leaders and anatomic pathologists can contribute to innovative treatment approaches, including wearable technology and precision medicine.
The speakers also noted that labs must learn to work collaboratively with payers—perhaps through health information technology (HIT)—to establish best practices that improve reimbursements on claims for novel genetic tests.
Harnessing the ever-increasing volume of diagnostic data that genetic testing produces should be a high priority for labs, said William Morice II, MD, PhD, CEO and President of Mayo Clinic Laboratories.
“There will be an increased focus on getting information within the laboratory … for areas such as genomics and proteomics,” Morice told the keynote audience at the Executive War College on Wednesday.
“Wearable technology data is analyzed using machine learning. Clinical laboratories must participate in analyzing that spectrum of diagnostics,” said William Morice II, MD, PhD (above), CEO and President of Mayo Clinic Laboratories. Morice spoke during this week’s Executive War College.
Precision Medicine Efforts Include Genetic Testing and Wearable Devices
For laboratories new to genetic testing that want to move it in-house, Morice outlined effective first steps to take, including the following:
- Determine and then analyze the volume of genetic testing that a lab is sending out.
- Research and evaluate genetic sequencing platforms that are on the market, with an eye towards affordable cloud-based options.
- Build a business case to conduct genetic tests in-house that focuses on the long-term value to patients and how that could also improve revenue.
Morice suggested that neuroimmunology is a reasonable place to start with genetic testing. Mayo Clinic Laboratories found early success with tests in this area because autoimmune disorders are rising among patients.
A related area for clinical laboratories and pathology practices to explore is their role in how clinicians treat patients using wearable technology.
For example, according to Morice, Mayo Clinic has monitored 20,000 cardiac patients with wearable devices. The data from the wearable devices—which includes diagnostic information—is analyzed using machine learning, a subset of artificial intelligence.
In one study published in Scientific Reports, scientists from Mayo’s Departments of Neurology and Biomedical Engineering found “clear evidence that direct seizure forecasts are possible using wearable devices in the ambulatory setting for many patients with epilepsy.”
Clinical laboratories fit into this picture, Morice explained. For example, depending on what data it provides, a wearable device on a patient with worsening neurological symptoms could trigger a lab test for Alzheimer’s disease or other neurological disorders.
“This will change how labs think about access to care,” he noted.
For Payers, Navigating Genetic Testing Claims is Difficult
While there is promise in genetic testing and precision medicine, from an administrative viewpoint, these activities can be challenging for payers when it comes to verifying reimbursement claims.
“One of the biggest challenges we face is determining what test is being ordered. From the perspective of the reimbursement process, it’s not always clear,” said Cristi Radford, MS, CGC, Product Director at healthcare services provider Optum, a subsidiary of UnitedHealth Group, located in Eden Prairie, Minnesota. Radford also presented a keynote at this year’s Executive War College.
Approximately 400 Current Procedural Terminology (CPT) codes are in place to represent the estimated 175,000 genetic tests on the market, Radford noted. That creates a dilemma for labs and payers in assigning codes to novel genetic tests.
During her keynote address, Radford showed the audience of laboratory executives a slide that charted how four labs submitted claims for the same high-risk breast cancer panel. CPT code choices varied greatly.
“Does the payer have any idea which test was ordered? No,” she said. “It was a genetic panel, but the information doesn’t give us the specificity payers need.”
In such situations, payers resort to prior authorization to halt these types of claims on the front end so that more diagnostic information can be provided.
“Plans don’t like prior authorization, but it’s a necessary evil,” said Jason Bush, PhD, Executive Vice President of Product at Avalon Healthcare Solutions in Tampa, Florida. Bush co-presented with Radford.

Payers Struggle with ‘Explosion’ of Genetic Tests
In “UnitedHealth’s Optum to Offer Lab Test Management,” Dark Daily’s sister publication The Dark Report, covered Optum’s announcement that it had launched “a comprehensive laboratory benefit management solution designed to help health plans reduce unnecessary lab testing and ensure their members receive appropriate, high-quality tests.”
Optum sells this laboratory benefit management program to other health plans and self-insured employers. Genetic test management capabilities are part of that offering.
As part of its lab management benefit program, Optum is collaborating with Avalon on a new platform for genetic testing that will launch soon and focus on identifying test quality, streamlining prior authorization, and providing test payment accuracy in advance.
“Payers are struggling with the explosion in genetic testing,” Bush told Executive War College attendees. “They are truly not trying to hinder innovation.”
For clinical laboratory leaders reading this ebriefing, the takeaway is twofold: Genetic testing and resulting precision medicine efforts provide hope in more effectively treating patients. At the same time, the genetic test juggernaut has grown so large so quickly payers are finding it difficult to manage. Thus, it has become a source of continuous challenge for labs seeking reimbursements.
Heath information technology may help ease the situation. But, ultimately, stronger communication between labs and payers—including acknowledgement of what each side needs from a business perspective—is paramount.
