Biodesix Oral Presentation At SITC: Testing Methodology May Identify Primary Immunotherapy Resistance In Patients


Posted on: 07 Nov 17

BOULDER, Colo., Nov. 07, 2017 (GLOBE NEWSWIRE) -- Biodesix® chief technology officer, Dr. Heinrich Roder, will give an oral presentation discussing a proprietary test development methodology that uses machine learning to correlate MALDI-ToF mass spectra from patient pre-treatment serum with clinical outcomes and benefit from therapy, specifically immunotherapies. The presentation will highlight the importance of evaluating the circulating proteome for predicting response to checkpoint inhibition and HD-IL2 therapy. Dr. Roder will also discuss the immune phenotype, known as primary immune resistance, that identifies patients who may obtain little long-term benefit from single agent anti-PD1, anti-CTLA4, or HD-IL2 treatment and who may obtain benefit from additional treatment with combinations of immunotherapies.

“Not all patients respond to immunotherapies,” said Dr. Heinrich Roder. “The pre-treatment circulating proteome contains information that can predict durable benefit from immunotherapies. Our test development platform, an established methodology, can be used to design proteomic tests that answer important clinical questions regarding prognosis, patient selection, treatment monitoring, and drug target discovery related to the use of immunotherapies and other therapies for oncology.”

In addition, the company is presenting two posters on tests created using the methodology described in Dr. Roder’s oral presentation. In the first study, “Proteomic biomarker analysis of metastatic melanoma patients treated with anti-PD-1 checkpoint blockade,” a pre-treatment test associated with acute phase reactants, wound healing and complement activation was shown to successfully stratify melanoma patients into groups with better and worse progression-free and overall survival. The second study, “Mass spectrometry-based test predicts outcome on anti-PD-1 therapy for patients with advanced non-small cell lung cancer,” describes an extension of Biodesix’s melanoma program to non-small cell lung cancer (NSCLC), using a test to identify patients with advanced NSCLC who were likely to have better or worse survival on anti-PD-1 therapy. It also showed promise in a blinded validation cohort of patients with brain metastases.

The posters and the oral presentation, titled “Biomarkers for primary immunotherapy resistance based on the circulating proteome,” will be part of the program of the 32nd annual meeting of the Society for the Immunotherapy of Cancer, in National Harbor, MD.
