Boulder, Colorado – May 21, 2013 – Biodesix, Inc., announced that final results of the first completed biomarker-stratified, validation study in oncology will be presented at the 2013 American Society of Clinical Oncology (ASCO) Annual Meeting, May 31st – June 4th, 2013.

The Randomized Proteomic Stratified Phase III Study of Second Line Erlotinib (E) versus Chemotherapy (CT) in Patients with Inoperable Non-Small Cell Lung Cancer (PROSE) study, evaluates the ability of Biodesix’ VeriStrat® test to differentially predict survival in second-line non-small cell lung cancer patients treated with either erlotinib or standard-agent chemotherapy.

The study’s Prinicpal Investigator Vanesa Gregorc, M.D., of the Department of Oncology at the Scientific Institute of the University Hospital San Raffaele in Milan, Italy, will present the findings at ASCO on Monday, June 3 at 4:30 p.m.

VeriStrat is a multivariate, blood-based, protein test currently available to help physicians guide treatment decisions for patients with advanced non-small cell lung cancer. The test identifies patients who are likely to have good or poor outcomes after treatment with either epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) therapy such as erlotinib or with chemotherapy. VeriStrat is based on Biodesix’ proprietary proteomics platform which enables the discovery of multivariate classifiers that characterize a patient’s condition or likely outcome in response to therapy.

“To add to the clinical validation of a biomarker, it can be beneficial to conduct a prospective, phase III randomized trial that compares alternative treatments within the biomarker groups,” said David Brunel, CEO of Biodesix. “PROSE is the first, prospective, phase III study in oncology that has utilized this robust trial design.”

Boulder, Colo. – April 2, 2013 – Biodesix, Inc., a molecular diagnostic company dedicated to personalizing medicine, today announced the online release of a peer-reviewed study demonstrating that physicians are using the company’s VeriStrat test to help guide treatment decisions for patients with advanced non-small lung cell cancer (NSCLC). Details of the study and its results appeared online ahead of print in Current Medical Research & Opinion.

“The results of this study show that when physicians incorporated the VeriStrat test into their clinical practice, it had a significant impact on their treatment decisions,” said David Brunel, CEO of Biodesix. “This data confirms that VeriStrat provides valuable information to physicians as they recommend a therapy for individual patients—particularly patients with advanced NSCLC who may not be receiving personalized therapy due to lack of a genetic mutation or squamous histology.”

VeriStrat is a novel, multivariate, serum protein test designed to provide oncologists with information to help them choose between erlotinib and single-agent chemotherapy when treating advanced lung cancer patients. The test, which requires only a simple blood draw, provides results in less than 72 hours, allowing physicians to make quick treatment decisions.

The published study, titled “The Impact of Serum Based Proteomic Mass Spectrometry Test on Treatment Recommendations in Advanced Non Small Cell Lung Cancer,” shows that VeriStrat significantly influences therapy recommendations. The study reveals that 90 percent of physicians’ post-test treatment recommendations positively correlated with results of the VeriStrat test: Physicians overwhelmingly chose erlotinib therapy when a patient’s test resulted in “VeriStrat Good,” but selected alternative therapy when a patient’s test resulted in a reading of “VeriStrat Poor.” In addition, the study showed that 40 percent of post-test treatment recommendations represented a change from the physicians’ pre-test treatment consideration.

“It’s no longer sufficient to only prove the clinical utility of a molecular test. Developers must also provide data early on, and then subsequently validate that data, showing that the test is being adopted and results are appropriately influencing clinical practice,” said John Hornberger, MD, MS, FACP, of Stanford University and Cedar Associates LLC, and an author of the study. “This study is the first showing that early physician users of the test are making clinically relevant practice management changes based on the results of the test.”

Previous clinical validation studies of the VeriStrat test have shown that the group of patients classified as “VeriStrat Good” has significantly longer overall survival following treatment with erlotinib when compared with patients who are classified as “VeriStrat Poor.” Most recently, an article in the Journal of Thoracic Oncology demonstrated that the VeriStrat test is predictive of differential treatment outcomes between erlotinib and chemotherapy.

Data Published in Journal of Thoracic Oncology

Boulder, Colo. – February 20, 2013 – A new study published online ahead of print in the Journal of Thoracic Oncology concludes that Biodesix’ VeriStrat test was predictive of survival outcomes between erlotinib and gemcitabine. The study, “A Retrospective Analysis of VeriStrat Status on Outcome of a Randomized Phase II Trial of First-Line Therapy with Gemcitabine, Erlotinib, or the Combination in Elderly Patients (Age 70 Years or Older) with Stage IIIB/IV Non–Small-Cell Lung Cancer” was conducted by lead investigators at the University of North Carolina Lineberger Comprehensive Cancer Center and Biodesix.   This is the fourth VeriStrat study to be published in this prestigious medical journal. The paper was also the subject of an oral presentation at the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology.

VeriStrat is a novel, multivariate serum protein test that helps oncologists to effectively personalize therapy. The new study, which will appear in the April 2013 issue of the Journal of Thoracic Oncology, concludes that in this population, patients with VeriStrat Poor status should not receive erlotinib therapy but may be good candidates for gemcitabine treatment.

In the retrospective analysis — conducted by Thomas Stinchcombe, MD, Associate Professor at the UNC Lineberger Comprehensive Cancer Center, and his colleagues —  105 patients received VeriStrat testing on serum or plasma samples taken prior to initiation of therapy. Sixty-three (60%) of these samples were classified as “VeriStrat Good” and 35 samples (33%) were classified as “VeriStrat Poor.”

In the gemcitabine-treated arm, results showed no significant difference between patients classified as VeriStrat Good and VeriStrat Poor, as measured by progresssion free survival (PFS) and overall survival (OS). However, in the erlotinib treated arm, patients classified as VeriStrat Good had a statistically significant improvement in PFS (p=0.002) and OS (p=0.014) compared with patients classified as VeriStrat Poor. Patients classified as VeriStrat Good also had better PFS (p=0.027) and a strong trend toward better OS outcomes (p=0.051) in the erlotinib plus gemcitabine arm compared to patients classified as VeriStrat Poor.

Researchers concluded in multivariate analysis that the VeriStrat test was predictive of both PFS and OS outcomes between the erlotinib and gemcitabine arms ( p<0.001, p=0.017, respectively) and that further studies utilizing VeriStrat to select more beneficial treatment regimens for lung cancer patients are warranted.

“These study results are consistent with other VeriStrat data; across multiple studies; patients classified as VeriStrat Poor consistently have worse outcomes on erlotinib therapy than patients classified as VeriStrat Good,” said Dominic Spinella, PhD, Vice President of Clinical Development and Medical Affairs at Biodesix. “Importantly, this is the first study where we have identified a viable treatment option for elderly lung cancer patients with VeriStrat Poor classification: single agent chemotherapy with gemcitabine. We are pleased that this publication will add to the body of literature validating VeriStrat’s clinical utility and to continue researching therapies that benefit this group of patients.”

Lung cancer specialist Karen Reckamp, M.D., is tired of seeing what the disease does to her patients. She’s deep into researching targeted therapies for lung cancer so she can offer up better treatment options.

The disease has been the leading cause of cancer deaths for a long time, but researchers like her are making some progress.  Along these lines, Reckamp recently presented a study at lung cancer conference in Chicago on a possible test to help choose the most effective therapy for patients with the most common form of lung cancer. The test might predict which non-small-cell lung cancer patients would respond better to a combination treatment, rather than one drug alone.

It all comes down to a blood test called VeriStrat. (Read more at City of Hope’s Breakthroughs)

Encouraging New Data Presented at Chicago Multidisciplinary Symposium in Thoracic Oncology

Boulder, Colorado and Chicago – September 6, 2012 –  Results from the VeriStrat analysis of serum or plasma samples taken from a Phase II study evaluating erlotinib, gemcitabine, and erlotinib plus gemcitabine in elderly advanced NSCLC patients were presented today  at the Chicago Multidisciplinary Symposium  in Thoracic Oncology. The retrospective analysis showed that the VeriStrat test was able to identify patients more likely to have a slower progression of disease and longer overall survival when treated with either single agent chemotherapy, gemcitabine, or targeted therapy, erlotinib.

Data was presented by Thomas Stinchcombe, MD, Associate Professor of Hematology/Oncology at the UNC Lineberger Comprehensive Cancer Center.  VeriStrat testing was performed on pretreatment serum or plasma samples from 105 study patients with classifications of 63 as VeriStrat Good (60%) and 35 as VeriStrat Poor (33%).   Results showed in the gemcitabine treated arm, there was no significant difference between patients classified as VeriStrat Good and VeriStrat Poor for both progression free survival (PFS) and overall survival (OS).  However, in the erlotinib treated arm, patients classified as VeriStrat Good had a statistically significant improvement in PFS (p=0.002) and OS (p=0.014) compared to patients classified as VeriStrat Poor.  Patients classified as VeriStrat Good also had better PFS (p=0.027) and a strong trend toward better OS outcomes (p=0.051) in the erlotinib plus gemcitabine arm compared to patients classified as VeriStrat Poor.

Researchers concluded in multivariate analysis that the VeriStrat test was predictive of both PFS and OS outcomes between erlotinib and gemcitabine  arms ( P <0.001, P=0.017, respectively) and that further studies utilizing VeriStrat to select more beneficial treatment regimens for lung cancer patients are warranted.

Dominic Spinella, PhD, Vice President of Clinical Development and Medical Affairs at Biodesix commented “It is exciting to see that VeriStrat consistently, and across multiple studies, identifies patients who may be good candidates to receive erlotinib therapy.  Importantly, this is the first study where we have identified a possible treatment option for those patients who are poor candidates for erlotinib: single agent chemotherapy with gemcitabine.  These data support a role for VeriStrat in helping oncologists select the most appropriate treatment for their lung cancer patients.”
