Novel T Cell Measurement System by Novoviah Pharmaceuticals Demonstrates High Accuracy for Clinical Disease Detection and Monitoring of Celiac Disease
"Non-invasively monitoring T cell reactivity opens the door to transformative clinical applications, particularly in drug development."
The Novoleukin TM test platform, developed specifically for clinical use, measures T Cell reactivity in fresh whole blood after 24-hour in vitro stimulation with a target antigen. The proprietary technology boosts T Cell activity after blood collection, enabling accurate cytokine biomarker measurement and comparison with unstimulated controls. This can be used to monitor disease reactivity status and the effectiveness of prospective therapeutics.
Originally developed for multi-center clinical trials, the Novoleukin TM system has potential for broader clinical use. Its utility and performance were demonstrated in collaboration with WEHI researchers who analyzed blood samples from 181 volunteers to identify the presence and assess the severity of celiac disease.
The results show high sensitivity (90%) and specificity (95%) in detecting celiac disease, even in patients following a strict gluten free diet which normally confounds traditional diagnostic methods.
The test detects as few as one gluten-specific T lymphocyte in one milliliter of blood or one per million CD4+ T cells. This level of sensitivity in a straightforward blood test is a landmark technical achievement and promises to impact patient care in many fields and accelerate immunotherapy and vaccine development.
Associate Professor Jason Tye-Din, Head of WEHI's Celiac Research Laboratory and a gastroenterologist at the Royal Melbourne Hospital, highlighted the test's promise for simplifying diagnosis and removing a significant barrier in current diagnostics.
'By stimulating T cells after a blood draw, patients can avoid the need to return to gluten and the suffering that often comes with that – for the sole purpose of diagnosis. That is a major step towards improving outcomes for patients.'
The test was also predictive of patient responses during gluten challenge protocols, underscoring its utility in stratifying patients for clinical research and tailoring therapeutic strategies.
Dr Robert Anderson, co-founder of Novoviah Pharmaceuticals, current President of the International Society for the Study of Celiac Disease and a practicing gastroenterologist, said the study highlights the potential of practical, blood-based T cell diagnostics in clinic and for clinical trials.
'The test is designed for ease of use in the clinical setting. It can be prepared without specialist equipment and then sent for highly sensitive laboratory analysis. The protocol is simple and reproducible enabling easy rollout across multiple sites,' Dr Anderson said.
The Novoleukin test's ability to detect disease and measure changes in immune response has proven invaluable in the developmental journey for drug developers.
'Non-invasively monitoring T cell reactivity opens the door to transformative clinical applications, particularly in drug development,' Dr Anderson added.
'The platform is already being used by leading biopharma partners to evaluate immune responses during celiac disease clinical trials, offering real-time insights into treatment efficacy.'
Novoviah is actively expanding the diagnostic applications of the Novoleukin platform across additional immune-mediated diseases, including viral infection, autoimmune conditions and some cancers, aiming to bring T cell-guided insights to clinical and research settings.

Sarepta Therapeutics Provides Clarifying Statement on ELEVIDYS
CAMBRIDGE, Mass., July 25, 2025--(BUSINESS WIRE)--Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today issued the following statement: Just before 6:00 p.m. ET today, the U.S. Food and Drug Administration (FDA) issued a press release announcing an investigation into the death of an eight-year-old Duchenne muscular dystrophy (Duchenne) patient who had received ELEVIDYS (delandistrogene moxeparvovec) gene therapy. The death of this patient was deemed unrelated to treatment with ELEVIDYS. As reported yesterday by Naomi Kresge at Bloomberg News: Roche Holding AG says the recent death of a patient in Brazil who had been treated with gene therapy Elevidys for Duchenne muscular dystrophy is unrelated to the treatment. * The boy wasn't a clinical trial participant; reporting physician assessed his death as being unrelated to the gene therapy, Roche says in statement* Death was reported to health authorities* Roche, which markets Sarepta's Duchenne treatment Elevidys outside the US, declines to comment on the boy's age or details of the case Sarepta reported this event to FDA on June 18, 2025, via the FDA's postmarketing electronic database, FAERS. At Sarepta, patient safety and well-being are always our top priority. We are committed to upholding the highest safety standards for all of our therapies, and do so in accordance with applicable law and commitment to full regulatory transparency. ELEVIDYS is the only approved gene therapy for families and children devastated by Duchenne, a rare, progressive and ultimately fatal disease. We remain committed to working closely with the FDA to ensure that all decisions are grounded in science and the best interests of patients, considering the compelling need of these families to access disease-modifying therapy. About ELEVIDYS (delandistrogene moxeparvovec-rokl)ELEVIDYS (delandistrogene moxeparvovec-rokl) is a single-dose, adeno-associated virus (AAV)-based gene transfer therapy for intravenous infusion designed to address the underlying genetic cause of Duchenne muscular dystrophy – mutations or changes in the DMD gene that result in the lack of dystrophin protein – through the delivery of a transgene that codes for the targeted production of ELEVIDYS micro-dystrophin in skeletal muscle. ELEVIDYS is indicated for the treatment of Duchenne muscular dystrophy (DMD) in individuals at least 4 years of age. For patients who are ambulatory and have a confirmed mutation in the DMD gene For patients who are non-ambulatory and have a confirmed mutation in the DMD gene. The DMD indication in non-ambulatory patients is approved under accelerated approval based on expression of ELEVIDYS micro-dystrophin in skeletal muscle. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). IMPORTANT SAFETY INFORMATION CONTRAINDICATION: ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene. WARNINGS AND PRECAUTIONS:Infusion-related Reactions: Infusion-related reactions, including hypersensitivity reactions and anaphylaxis, have occurred during or up to several hours following ELEVIDYS administration. Closely monitor patients during administration and for at least 3 hours after the end of infusion. If symptoms of infusion-related reactions occur, slow, or stop the infusion and give appropriate treatment. Once symptoms resolve, the infusion may be restarted at a lower rate. ELEVIDYS should be administered in a setting where treatment for infusion-related reactions is immediately available. Discontinue infusion for anaphylaxis. Acute Serious Liver Injury: Acute serious liver injury has been observed with ELEVIDYS, and administration may result in elevations of liver enzymes (such as GGT, GLDH, ALT, AST) or total bilirubin, typically seen within 8 weeks. Patients with preexisting liver impairment, chronic hepatic condition, or acute liver disease (e.g., acute hepatic viral infection) may be at higher risk of acute serious liver injury. Postpone ELEVIDYS administration in patients with acute liver disease until resolved or controlled. Prior to ELEVIDYS administration, perform liver enzyme test and monitor liver function (clinical exam, GGT, and total bilirubin) weekly for the first 3 months following ELEVIDYS infusion. Continue monitoring if clinically indicated, until results are unremarkable (normal clinical exam, GGT, and total bilirubin levels return to near baseline levels). Systemic corticosteroid treatment is recommended for patients before and after ELEVIDYS infusion. Adjust corticosteroid regimen when indicated. If acute serious liver injury is suspected, consultation with a specialist is recommended. Immune-mediated Myositis: In clinical trials, immune-mediated myositis has been observed approximately 1 month following ELEVIDYS infusion in patients with deletion mutations involving exon 8 and/or exon 9 in the DMD gene. Symptoms of severe muscle weakness, including dysphagia, dyspnea, and hypophonia, were observed. Limited data are available for ELEVIDYS treatment in patients with mutations in the DMD gene in exons 1 to 17 and/or exons 59 to 71. Patients with deletions in these regions may be at risk for a severe immune-mediated myositis reaction. Advise patients to contact a physician immediately if they experience any unexplained increased muscle pain, tenderness, or weakness, including dysphagia, dyspnea, or hypophonia, as these may be symptoms of myositis. Consider additional immunomodulatory treatment (immunosuppressants [e.g., calcineurin-inhibitor] in addition to corticosteroids) based on patient's clinical presentation and medical history if these symptoms occur. Myocarditis: Acute serious myocarditis and troponin-I elevations have been observed following ELEVIDYS infusion in clinical trials. If a patient experiences myocarditis, those with pre-existing left ventricle ejection fraction (LVEF) impairment may be at higher risk of adverse outcomes. Monitor troponin-I before ELEVIDYS infusion and weekly for the first month following infusion and continue monitoring if clinically indicated. More frequent monitoring may be warranted in the presence of cardiac symptoms, such as chest pain or shortness of breath. Advise patients to contact a physician immediately if they experience cardiac symptoms. Preexisting Immunity against AAVrh74: In AAV-vector based gene therapies, preexisting anti-AAV antibodies may impede transgene expression at desired therapeutic levels. Following treatment with ELEVIDYS, all patients developed anti-AAVrh74 antibodies. Perform baseline testing for presence of anti-AAVrh74 total binding antibodies prior to ELEVIDYS administration. ELEVIDYS administration is not recommended in patients with elevated anti-AAVrh74 total binding antibody titers greater than or equal to 1:400. Adverse Reactions: The most common adverse reactions (incidence ≥5%) reported in clinical studies were vomiting, nausea, liver injury, pyrexia, and thrombocytopenia. Report negative side effects of prescription drugs to the FDA. Visit or call 1-800-FDA-1088. You may also report side effects to Sarepta Therapeutics at 1-888-SAREPTA (1-888-727-3782).
