Virax believes this represents a significant potential U.S. testing opportunity in an area where many patients are often assessed through symptoms and exclusion, rather than objective immune biomarkers of the type ViraxImmune\u2122 is being developed to assess.<\/p>\n<p>\n        <b>Highlights:<\/b>\n      <\/p>\n<ul type=\"disc\">\n<li>In the pilot dataset, ViraxImmune\u2122 demonstrated measurable separation between PAIS patients and healthy controls and achieved 88% specificity and 92% positive predictive value (&#8220;PPV&#8221;).<\/li>\n<li>ViraxImmune\u2122 has now been evaluated in more than 120 subjects in the Company&#8217;s ongoing UK clinical study in Long COVID, ME\/CFS and related post-acute infection syndromes.<\/li>\n<li>Virax is preparing for its next major development milestone: a larger clinical validation analysis involving previously collected samples from 300 additional participants, with analysis expected to begin in Q4 2026 and results expected in Q1 2027.<\/li>\n<li>Findings support continued advancement toward Virax&#8217;s intended U.S. market-entry strategy: an initial PAIS-focused U.S. Laboratory Developed Test (&#8220;LDT&#8221;) route, with broader in vitro diagnostic (&#8220;IVD&#8221;) development planned over time.<\/li>\n<\/ul>\n<p>If validated in larger studies, ViraxImmune\u2122 could become one of the first objective immune-profiling approaches developed specifically for Long COVID, ME\/CFS and related post-acute infection syndromes. Virax believes this approach could support a differentiated diagnostic strategy in an area of significant unmet need, with potential applications in patient stratification, clinical decision-making<s>,<\/s> longitudinal monitoring and therapeutic development.<\/p>\n<p>&#8220;These early pilot data mark an important step in the development of ViraxImmune\u2122 as a potential objective immune-profiling test for Long COVID, ME\/CFS and related post-acute infection syndromes,&#8221; said James Foster, Chairman and Chief Executive Officer of Virax Biolabs. &#8220;The observed separation between patients and healthy controls, together with encouraging early performance metrics, supports our confidence that ViraxImmune\u2122 has the potential to address a major unmet diagnostic need as we advance toward our planned U.S. LDT-first route to market.&#8221;<\/p>\n<p>&#8220;Patients with Long COVID, ME\/CFS and related post-acute infection syndromes often face lengthy diagnostic journeys and limited objective testing options,&#8221; said Dr. Sean Knight, MD, PhD, Principal Investigator at the Lydia Becker Institute of Immunology and Inflammation, University of Manchester, and Consultant Respiratory Physician at Northern Care Alliance NHS Foundation Trust. &#8220;Objective immune profiling may help improve how these patients are assessed, stratified and monitored over time. These early pilot findings are encouraging and support further clinical validation of ViraxImmune\u2122.&#8221;<\/p>\n<p>Virax will host an investor webcast on May 26, 2026, at 4:15 p.m. ET to review the early ViraxImmune\u2122 dataset, discuss the clinical and commercial implications of the findings, and outline the Company&#8217;s planned path toward larger clinical validation, assay finalization and U.S. market entry.
