Press Release

Biodesix Announces PD-L1 Collaboration with Professor Fred R. Hirsch


Posted on: 31 Jan 18

BOULDER, Colo., Jan. 31, 2018 (GLOBE NEWSWIRE) -- Biodesix® announced a new collaboration agreement with PD-L1 expert Professor Fred R. Hirsch, MD, PhD, laboratory director at the Hirsch Biomarker Laboratory at the University of Colorado Cancer Center in Aurora, CO. Dr. Hirsch’s lab will provide analysis of prospectively collected tissue samples with matched plasma from patients diagnosed with non-small cell lung cancer (NSCLC). The announcement follows a poster presented by Biodesix, including preliminary data evaluating a blood-based, PD-L1 liquid biopsy test in development that uses plasma-derived RNA. The data were presented last week at the ASCO-SITC conference.

“The results of our pilot prospective study led us to conclude that although the development of a blood-based, PD-L1 mRNA assay was achieved, de-centralized IHC methods may not be the most suitable way to assess the clinical utility of RNA blood assays,” said Dr. Gary Pestano, Vice President of Development for Biodesix. “IHC testing for PD-L1 expression is a complex undertaking and it has many challenges,” added Dr. Hirsch. “Some of these are technical in nature and related to the number of antibodies used to perform IHC and variability in pathologists’ interpretation. We are very happy to be working with the Biodesix team and their physician collaborators on expanding their studies in our centralized IHC testing laboratory.”

PD-L1, or programmed cell death ligand-1, is an important protein biomarker; when overexpressed in cancer patients, PD-L1 is a target for specific immunotherapies called checkpoint inhibitors. Several such therapies have received FDA approval. 

The study, “Performance verification of a plasma-based PD-L1 test that reliably measures mRNA expression from patients with NSCLC,” refers to a test in development at Biodesix that uses multiplexed droplet digital™ PCR (ddPCR) detection of circulating PD-L1 mRNA. The data demonstrates the robustness of the PD-L1 RNA assay from blood.
