Next-generation diagnostics for chronic inflammation and immune dysfunction
Our lead product, ViraxImmune is designed to be one of the first assays to objectively assess immune dysfunction in post-acute infection syndromes (PAIS), where there are currently no approved objective diagnostic tests in major markets. An objective result could help reduce diagnostic uncertainty, support patient stratification, and guide treatment management.
N A S D A Q : V R A X 3
PAIS conditions: A large, under-served diagnostic category
Millions of people each year are diagnosed with PAIS conditions including ME/CFS, Long COVID, and post-treatment Lyme disease (PTLD)
$6.5B
Expert estimates suggest an
economic burden in excess of
$25bn in the US alone1-3
There is currently no widely adopted objective test for PAIS. This prevents accurate diagnoses, clinical management, and therapeutic trials4-6

N A S D A Q : V R A X 4
Currently, clinicians speculate PAIS based on the exclusion of other diagnoses.
A validated, objective immune dysfunction diagnostic, such as ViraxImmune , could help shorten time-to-diagnosis and reduce overall diagnostic burden and cost for both patients and payors.

PAIS and immune dysfunction: Evolving treatment landscapes
EXAMPLES OF TREATMENT AREAS USED IN LONG COVID AND ME/CFS CARE
Autonomic / cardiovascular
Beta blockers, ivabradine, midodrine, pyridostigmine
Immune / inflammatory
Low-dose naltrexone, ketotifen, IVIG/SCIG, rapamycin
Long COVID and ME/CFS currently lack FDA-approved treatments, with real-world care spanning a broad range of symptom-targeted interventions.1
Antiviral /
persistence-targeted
Herpesvirus antivirals,
SARS-CoV-2 antivirals,
maraviroc
Supportive / symptom management
Antihistamines, compression garments, pacing, lymphatic drainage, HBOT
ViraxImmune is intended to help reduce diagnostic uncertainty and support clinical management, by helping to identify the underlying immune dysfunction phenotype in PAIS.
As treatment pathways evolve, objective tools to identify and stratify relevant patient populations will become increasingly important.

Reportable result
Planned path to market:
Initial LDT launch
PAIS (Post-Acute Infection Syndrome) is the lead indication
Additional indications to be advanced selectively as clinical data matures
Subsequent IVD launch
IVD intended use: aid to clinical diagnosis of Long COVID (post-acute sequelae of SARS-Cov-2 infection, PASC)
Subject to FDA De Novo clearance
N A S D A Q : V R A X 7
Our market access strategy targets the established 'Gapfill' CMS reimbursement pathway
to establish payment when no comparable test exists, facilitating the commercial
availability and long-term valuation goals for ViraxImmune
Phase
Coding Mechanism
Market Access Objective
Launch
CPT 86849
(Unlisted immunology
procedure)
Utilizing the Unlisted Immunology code for day-one billing - used for novel or emerging immunology assays where no existing CPT code applies
Initial US LDT billing is expected to begin with an illustrative initial rate / allowable of $812
Growth
PLA Code
(Proprietary)
Transition to a Proprietary Laboratory Analysis (PLA) code providing a unique identifier for ViraxImmune
Maturity
Category I CPT
Evolution to a permanent, widely recognized CPT code as ViraxImmune
demonstrates clinical utility and market penetration
N A S D A Q : V R A X 8
Following initial US LDT billing under CPT 86849, planned transition to a Proprietary (PLA) identifier would support the next stage of reimbursement development,
followed over time by a permanent Category I framework.
Future reimbursement expectations would then be based on National Payor typical rates.
