Vivoryon Therapeutics N.V. Reports H1 2026 Financial Results and Provides Business Update Strategic partnering remains a key priority, with multiple strategic discussions progressing, including advanced term sheet negotiations for a potential licensing agreement Gained further insight into varoglutamstat’s unique mechanism of action and therapeutic potential in kidney disease Financial guidance maintained: Vivoryon expects cash and cash equivalents to be sufficient for funding operations into Q4 2026 Management to host a conference call today at 3:00 pm CEST (9:00 am EDT) Halle (Saale) / Munich, Germany, August 6 , 2026 - Vivoryon Therapeutics N.V. (Euronext Amsterdam: VVY; NL00150002Q7) ( Vivoryon ), a clinical stage company developing small molecule medicines for inflammatory and fibrotic disorders, with a primary focus on kidney diseases, today announced financial results for the six-month period ended June 30, 2026, and provided a corporate update. The half year report is available on the Company’s website . “Throughout the first half of this year we continued to see increased external interest in varoglutamstat in kidney disease. We have made meaningful progress in our partnering efforts and are currently in advanced term sheet negotiations for a potential licensing agreement. Separately, a specialist kidney-focused investor is conducting an independent assessment of selected aspects of the varoglutamstat program in connection with its evaluation of a potential investment,” said Frank Weber, MD, CEO of Vivoryon. “We are highly encouraged by the level of external engagement and remain focused on securing the funding and partnership required to advance the Phase 2b program for varoglutamstat, and look forward to providing you with an update in due course.” H1 2026 and Post-Period Updates ezstandalone.cmd.push(function () { ezstandalone.showAds(131); }); Strategic Priorities Vivoryon's key strategic priority is to secure the funding necessary to advance varoglutamstat into a Phase 2b clinical study in patients with advanced diabetic kidney disease (DKD) stage 3b/4 in order to confirm the compelling data observed in the VIVIAD and VIVA-MIND studies. Throughout the reporting period and in recent months, multiple strategic discussions have been progressing. The Company is advancing negotiations with different parties towards securing beneficial partnerships for varoglutamstat in kidney disease and is currently in advanced term sheet negotiations for a potential licensing agreement. Separately, a specialist kidney-focused investor is conducting an independent assessment of selected aspects of the varoglutamstat program in connection with its evaluation of a potential investment. Vivoryon also continues to engage with additional strategic parties to maximize the full potential of the QPCT/L platform. Note that all ongoing negotiations and potential investments are subject to the typical risks and uncertainties associated with such processes and there can be no guarantee that any transaction or investment will materialize. Varoglutamstat Program The strong clinical and preclinical data and analyses generated to date continue to support advancement of varoglutamstat in advanced diabetic kidney disease (DKD). Vivoryon's Phase 2 clinical program with varoglutamstat has consistently demonstrated statistically significant and clinically meaningful improvements in kidney function (eGFR) versus placebo across two independent randomized, double-blind, placebo-controlled studies in elderly participants, VIVIAD and VIVA-MIND. Based on these findings, the Company is preparing to advance varoglutamstat into a dedicated Phase 2b clinical trial in patients with stage 3b/4 diabetic kidney disease (DKD), subject to securing additional funding and/or a strategic partnership. Further elucidated varoglutamstat’s MOA The Company continues to strengthen the scientific understanding of varoglutamstat‘s mechanism of action through an expanding preclinical data package. New preliminary findings from a CKD animal model show, on the molecular level, a significant beneficial effect of varoglutamstat on the endothelial cells in the kidney. These cells are a crucially important part of the kidneys’ filtration barrier, whose integrity is a key factor in maintaining kidney function. The new pathway analysis data support an improvement of endothelial cell function via activation of HIF pathways and upregulation of VEGF in response to varoglutamstat, which may lead to a reversal of capillary rarefaction, the prevention of endothelial cell death as well as vascular stabilization. Together with additional pre-clinical data on varoglutamstat’s molecular mechanisms, these findings further reinforce the therapeutic rationale for targeting QPCT/L in kidney disease. Vivoryon published a pre-recorded webcast in April 2026 which contextualizes pre-clinical data relating to the biological mechanisms of varoglutamstat’s kidney benefits observed in VIVIAD and VIVA-MIND. This included evidence of the role of QPCT and QPCTL in inflammation, fibrosis and collagen maturation, as well as data demonstrating the positive effects of varoglutamstat on podocytes, the specialized cells essential for maintaining kidney filtration function. The webcast is available here: Presented new analyses at key international medical meeting Vivoryon presented new analyses further validating QPCT/L as promising therapeutic targets in DKD at the World Congress of Nephrology (WCN) 2026 in Yokohama, Japan. The data reinforced previous findings that varoglutamstat's effect on eGFR was more pronounced in elderly participants with diabetes than in those without diabetes. Among participants with diabetes and lower baseline kidney function (mean eGFR of 60 mL/min/1.73m²), treatment effects were comparable to or greater than those observed in the overall diabetic population. Also presented at WCN were findings from a DKD mouse model showing significant improvements in inflammation, glomerulosclerosis and kidney function with varoglutamstat. Proposed clinical development plan in DKD The Company is planning to conduct a randomized, placebo-controlled Phase 2b study in patients with advanced DKD stage 3b/4 to confirm the compelling effects of varoglutamstat on kidney function observed in the VIVIAD and VIVA-MIND Phase 2 studies in elderly patients. Initiation of the Phase 2b and all future studies is subject to additional funding and/or partnership, which Vivoryon continues to actively explore. Corporate Update The Company plans to host its 2026 Annual General Meeting on September 29, 2026 in Amsterdam, The Netherlands. The convocation note and all related materials will be made available on the Company’s website in due time. Financial Results for the First Half of 2026 Revenues were zero in the six months ended June 30, 2026, as well as in the six months ended June 30, 2025. Research and development expenses decreased by EUR 1.1 million to EUR 1.7 million in the six months ended June 30, 2026, compared to EUR 2.8 million in the six months ended June 30, 2025. This reduction was largely attributable to a decrease in clinical development costs of EUR 0.6 million related to kidney research and a reduction of associated patent and consulting fees of EUR 0.2 million. General and administrative expenses were EUR 1.7 million in the six months ended June 30, 2026, compared to EUR 2.8 million in the six months ended June 30, 2025. The decrease of EUR 1.1 million was largely attributable to less non-cash-effective share-based personnel costs of EUR 0.4 million and a decrease in legal costs of EUR 0.4 million. Net loss for the six months ended June 30, 2026, was EUR 3.4 million, compared to EUR 5.5 million for the six months ended June 30, 2025. The Company held EUR 2.4 million in cash and cash equivalents as of June 30, 2026, compared to EUR 5.6 million as of December 31, 2025. Outlook & financial guidance As published on April 23, 2026, the issuance date of its annual Financial Statements 2025, the Company expects, based on its most recent financial and business plan, that its existing cash and cash equivalents will be sufficient to fund its operating plans into the fourth quarter of 2026, subject to the occurrence of unforeseen circumstances and without taking into account any potential financing through its standby equity purchase agreement (SEPA) as well as other potential additional financing transactions, if any. This cash runway guidance reflects an overall reduction in cash utilization while prudently investing in preparing to execute on the Company’s kidney disease strategy. Funding operations beyond its current guidance as well as initiation of the planned Phase 2b DKD study and all future studies are subject to further additional funding and/or partnership, which the Company continues to actively explore. The viability of the Company’s business beyond its current guidance is dependent on its ability to raise additional funds to finance its operations which also depends on the success of its research and development activities such as those focusing on exploring opportunities in kidney disease. The Company expects to have continued operating losses for the foreseeable future and the need to raise additional capital to finance its future operations. The Company has concluded that the ability to continue as a going concern in the financial year 2026, as stated in the Company’s Annual Report 2025 published on April 23, 2026, depends on the ability to generate additional funding. Please refer to the Company’s Annual Report 2025 for further information.
