European patent number 2,247,954 is the counterpart to U.S. patent number 7,867,775 and covers the use of VeriStrat for selection of head and neck cancer patients for treatment with targeted drugs. U. S. patent number 8,024,282 (‘282) provides additional intellectual property protection for the methods used with VeriStrat which are also related to Biodesix’ underlying core ProTS® technology.  Specifically, the ‘282 patent supports the Company’s methods for the reliable and reproducible classification of samples in clinical diagnostics using computer systems configured as probabilistic classifiers.  Related U.S. patent 7,906,342 covers Biodesix’ methods for using mass spectrometry of patient samples to monitor cancer patients being treated with drugs targeting the epidermal growth factor receptor (EGFR) pathway for response or non-responsiveness to the treatment.  Biodesix also received notice from the PTO that two additional patent applications covering the use of VeriStrat for monitoring of head and neck, as well as colorectal cancer patients being treated with drugs targeting the EGFR pathway have been allowed; these patents are expected to issue early in the first quarter of 2012.

Drug therapies targeting the EGFR pathway and related molecular targets play an increasingly important role in cancer therapy.  Identifying patients likely to benefit from this class of drugs is key to improving overall patient outcomes.

“The expansion of our patent estate is an integral part of our global strategy to protect VeriStrat and our technology platform,” commented David Brunel, Biodesix CEO.  “This protection strengthens our commercial position as a leading provider of diagnostics to personalize medicine for oncology patients.”

This study found that choosing second-line therapy on the basis of a protein-expression test modestly improved survival in patients with advanced non-small cell lung cancer (NSCLC). The four- to six-week survival advantage held up in a sensitivity analysis involving 10,000 simulations. Choosing second-line therapy on the basis of a protein-expression test modestly improved survival in patients with advanced non-small cell lung cancer (NSCLC), computer modeling suggested.

Use of the test to decide whether to give a patient an epidermal growth factor receptor (EGFR) inhibitor led to a predicted survival of 10 months versus eight to nine months with three conventional decision-making strategies.  Read more at MedPage Today.

VeriStrat is a serum proteomic test currently used to identify NSCLC patients who are likely to respond well, or poorly, to treatment using EGFR inhibitors. The Phase III Tykerb trial (designated EGF30008), was the first to evaluate VeriStat in breast cancer and also the first to assess the assay with an endocrine agent, Biodesix notes.

Pretreatment serum samples from 1041 of the 1286 patients enrolled in the EGF30008 study (81%) were classified as either VeriStrat Good or VeriStrat Poor.   In the Femara treatment arm,  patients who tested VeriStrat Good had a median progression free survival (PFS) of 10.8 months versus patients who tested VeriStrat Poor with 2.8 months (log rank p<0.0001, HR: 0.36).  The evaluation of the Femara plus Tykerb arm showed that patients who tested VeriStrat Good  had a median PFS of 11.4 months versus patients who tested VeriStrat Poor with 11.0 months (log rank p=0.53).  Multivariate analysis demonstrated a significant interaction between VeriStrat classification and treatment (interaction p=0.002), indicating that the VeriStrat test was predictive of a differential treatment effect between VeriStrat groups.  While in the Her2 positive population both VeriStrat groups benefitted from the addition of Tykerb to Femara, interestingly in the Her2 negative population  there was also a trend to a meaningful increase in PFS for patients who tested VeriStrat Poor (3.1 months vs. 11.0 months, p=0.068).

David Brunel, CEO of Biodesix commented, “We have a growing body of evidence regarding  the utility of VeriStrat in multiple tumor types, but EGF30008 represents the first study to evaluate our diagnostic test in breast cancer and the first with an endocrine agent. It’s encouraging to see that our test not only identifies a group of hormone receptor positive patients with poor outcomes on endocrine therapy,  but also has predictive power, showing that this group of patients can achieve similar outcomes to other patients when Tykerb is added to the treatment regimen, regardless of their Her2 status.”

The Product Differentiation Excellence Award is a prestigious recognition of Biodesix’ accomplishments in the cancer diagnostics industry, and of their first product, VeriStrat®. VeriStrat is a serum proteomic test currently available to help physicians guide therapy for patients with advanced lung cancer. Frost & Sullivan’s market research and analysis identified a critical need in lung cancer patient management for additional diagnostic information that enables better treatment decisions, particularly after initial therapy has failed. Frost & Sullivan analysts conclude that VeriStrat addresses this market need and state that “Biodesix’ VeriStrat test is changing the approach to the current paradigm of mutation-driven cancer diagnostics and measures instead an integrated effect of the host/tumor with respect to different drugs and drug combinations.” In the Best Practices report, analyst Winny Tan further notes that “Biodesix raises the bar in personalized medicine diagnostics by investing significantly in validation, clinical research, and basic R&D. The company is a best-in-practice diagnostic test developer for an industry that lacks clinically validated biomarkers through a commitment to improving patient outcomes.”

“We are honored to receive this award from Frost & Sullivan,” commented David Brunel, Biodesix’ Chief Executive Officer. “We are proud that our hard work to bring products for personalized medicine to physicians and patients has been recognized.”

In evaluating companies for the award, Frost & Sullivan considered key industry challenges that should be addressed by a differentiated diagnostic test, and benchmarked Biodesix’ performance against competitors across five key metrics: Unique Features/Functionality; Quality/Complexity; Customization; Match to Target Market Needs; and Brand Perception of the Uniqueness of the Product. Biodesix was selected as the leader in the cancer diagnostics category after garnering top marks in the Frost & Sullivan customized Decision Support Matrix, an analytical tool that compares companies’ performance relative to each other with an integration of quantitative and qualitative metrics.

The study retrospectively evaluated VeriStrat classification prior to the start of treatment with gefitinib, during the course of treatment, and at progression or withdrawal from treatment. VeriStrat is a serum proteomic test that classifies non-small cell lung cancer (NSCLC) patients according to an algorithm developed in a study of NSCLC patients treated with epidermal growth factor receptor (EGFR) inhibitors, such as erlotinib (Tarceva®) or gefitinib (Iressa®). The test identifies patients who are likely to have good (VeriStrat “Good”) or poor (VeriStrat “Poor”) outcomes after treatment with EGFR tyrosine kinase inhibitors (TKIs).

Blood samples from 111 patients with advanced NSCLC treated with gefitinib underwent VeriStrat testing. The study confirmed previous data that patients who tested VeriStrat Good prior to receiving gefitinib had longer median progression free survival (PFS) and overall survival (OS) as compared to patients who tested VeriStrat Poor. While during the course of treatment most patients (88%) maintained their baseline VeriStrat classification, at the time of treatment withdrawal or disease progression 30% of patients changed their VeriStrat classification. The majority of these changes were patients shifting from VeriStrat Good to VeriStrat Poor. Changes from Good to Poor at progression were associated with the development of new lesions, while the majority of patients maintaining their baseline VeriStrat Good classification had progression identified from metastases to the brain or increase of lesion diameter by RECIST criteria. The authors conclude that this finding may support the potential utility of VeriStrat in treatment monitoring, although more research is needed to support the use of VeriStrat in this setting.

Authors also surmise that the study results suggest that a VeriStrat Poor classification at baseline may be related to unknown resistance mechanisms to EGFR-TKI therapy, while a shift from VeriStrat Good classification to VeriStrat Poor may indicate a specific type of progression with the development of new cancer lesions. Biodesix is engaging in further research to explore the longitudinal behavior of VeriStrat classification and makes VeriStrat available to researchers developing targeted therapies to further understand its potential to help physicians guide therapy and to provide additional information on patient response to therapies.

The study retrospectively, and in a fully blinded fashion, applied the VeriStrat test to a subset of the patient population from a Phase I/II clinical trial of erlotinib plus sunitinib in RCC patients.  VeriStrat analysis was performed on all available serum samples.   Thirty-seven of 46 patients were classified as either VeriStrat Good or VeriStrat Poor based on the VeriStrat algorithm developed for non-small cell lung cancer (NSCLC).

The analysis showed that VeriStrat Good patients had a significantly longer PFS and OS versus VeriStrat Poor patients (PFS: median 12.3 vs. 4.7 months, log-rank p=0.025 and OS: median 38.4 vs. 11.6 months, log-rank p=0.045).   There was a statistically significant correlation between VeriStrat classification and Heng prognostic criteria, but not MSKCC classification.  VeriStrat  showed the potential to further refine current grouping of RCC patients, separating  MSKCC  intermediate patients into VeriStrat Good and VeriStrat Poor subgroups with statistically significantly different PFS (log-rank p = 0.030).

Heinrich Roder, D.Phil., Chief Technology Officer of Biodesix stated, “This data set shows that our test, VeriStrat, may be helpful in identifying specific and useful disease characteristics in RCC.  It is also exciting to see that our test is showing utility across multiple solid tumors.  Oncologists currently do not have a simple serum test that can be used across multiple tumor types.  We are continuously engaging in additional studies to further explore the full clinical utility of VeriStrat.”
