Exagen Inc. and Queen Mary University of London Announce Exclusive License and Collaboration to Develop Novel Patented Molecular Signatures for Rheumatoid Arthritis Biologic Therapeutic Selection
SAN DIEGO, Jan. 09, 2022 (GLOBE NEWSWIRE) -- Exagen Inc. (Nasdaq: XGN), a leading provider of autoimmune testing solutions, and Queen Mary University of London, announced today the execution of a research collaboration and exclusive license agreement. The collaboration will focus on development and optimization of patent-pending precision medicine approaches, based on RNA expression signatures, to personalize therapeutic agent selection for rheumatoid arthritis (RA) patients. Both parties will contribute to the development of the patent-pending assays, leading to the commercialization of novel molecular assays that segment patients according to gene expression in their synovial tissue biopsies.
RA is estimated to affect approximately two million patients in the United States and be twice as prevalent in women as in men and can be difficult to manage due to the variability in treatment response from patient to patient. Therapeutic agent selection for RA patients remains a significant unmet need. RA patients often try multiple therapies empirically before they find one that lowers their disease activity. The placement of an RA patient on an ineffective therapy risks progression and worsening of the disease, further damage to the joints, and significant wasted spend on expensive therapeutic agents. There are currently no reliable assays for predicting positive patient response prior to the selection of commonly prescribed biological therapeutic agents.
Building on Prof. Costantino Pitzalis and Dr. Myles Lewis’s molecular pathology definition of disease evolution and treatment response, Exagen has acquired an exclusive global license to a family of patent-pending assays pertaining to RNA expression patterns used in the prediction of patient response to commonly prescribed csDMARD and biological therapeutics for RA. The assays utilize minimally invasive synovial tissue biopsies as input, which are then assessed for RNA expression data. These data are then run through proprietary algorithms that provides actionable insights on predicted csDMARD and biological therapeutic response for RA patients based on an individual patient’s RNA expression patterns.
Prof. Pitzalis, Versus Arthritis Professor of Rheumatology and Deputy Director at the William Harvey Research Institute, Barts and The London School of Medicine and Dentistry, Queen Mary University of London stated, “I am excited to be part of this research collaboration with Exagen and am very much looking forward to contributing to the development of diagnostics aimed at bringing molecular pathology into clinical algorithms to better define the specific pathways driving disease diversity in individual patients. This would better inform clinicians on patients’ prognosis and enhance their ability to make informed decisions on drug prescribing. Exagen’s track record in bringing diagnostics to the market takes this opportunity to a completely new level, making the promise of precision medicine closer to clinical implementation.”
Prof. Pitzalis is a leading authority on rheumatoid arthritis. He leads a team of 50 clinical researchers and is the author of over 300 peer-reviewed publications in the field of inflammation, immunity, and arthritis. Prof. Pitzalis formulated this groundbreaking approach to gene expression patterns together with Dr. Myles Lewis, head of the bioinformatics/biostatistics group at the Centre for Experimental Medicine and Rheumatology. “We are excited to work with Prof. Pitzalis and Dr. Lewis at Queen Mary University of London to accelerate the development of their highly-innovative RNA-based biomarker assays to better serve RA patients. Prof. Pitzalis is a well-respected thought leader in the field of arthritis research, and Exagen is enthusiastically looking forward to collaborating with his group to bring exciting and groundbreaking products forward to improve the care continuum for rheumatoid arthritis patients,” said Ron Rocca, President and CEO of Exagen Inc. “Exagen is committed to developing and commercializing these assays to inform treatment decisions throughout the RA patient journey. We intend to market the new assays as AVISE® RADR (rheumatoid arthritis drug response).”
