Vivoryon Therapeutics N.V. Reports H1 2024 Progress Marked by Compelling Kidney Function Data and Execution of Strategy to Advance Varoglutamstat in Kidney Disease

• Primary focus is developing varoglutamstat, a Phase 2 investigational medicine with potential to improve kidney function in patients with kidney disease
• Statistically significant benefit of varoglutamstat on prospectively defined key kidney function endpoint (eGFR¹) and significant reduction of pro-inflammatory cytokine pE-CCL2 observed in VIVIAD Phase 2b AD study
• Substantially higher treatment benefit of varoglutamstat on eGFR observed in post-hoc diabetes subgroup² triggering plans to advance varoglutamstat into Phase 2 study in DKD³
• Gained further insight into AD results through clear evidence of differences between kidney and AD outcomes from PK/PD analysis and new target occupancy information
• Management to host a conference call today at 3:00pm CEST (9:00am EDT)
• Vivoryon to host a virtual Kidney Disease KOL (Key Opinion Leaders) webcast on Monday, September 30 at 3:00 pm CEST (9:00 am EDT) to elaborate on varoglutamstat’s potential in kidney disease with an emphasis on DKD

Halle (Saale) / Munich, Germany, September 12, 2024 – Vivoryon Therapeutics N.V. (Euronext Amsterdam: VVY; NL00150002Q7) (Vivoryon), a clinical stage company focused on the discovery and development of small molecule medicines to modulate the activity and stability of pathologically altered proteins, today announced financial results for the six-month period ended June 30, 2024, and provides a corporate update. The report is available on the Company’s website https://www.vivoryon.com/financial-information/.

“The VIVIAD Phase 2b study showed outstanding results in improving kidney function and we made strong progress during the first half of 2024 in forging a new development strategy for varoglutamstat in diabetic kidney disease (DKD),” said Frank Weber, MD, CEO of Vivoryon. “In parallel, we advanced pharmacokinetic and biomarker analyses which demonstrate a strong dose response of varoglutamstat on kidney function improvement. Furthermore, as we continue the evolution of our understanding of the Alzheimer’s disease (AD) VIVIAD results, we have generated the first evidence that varoglutamstat activity is required in the cells of the brain – not only in the cerebrospinal fluid – to stop the pathological process of pE-Abeta production.” He concluded, “The VIVIAD data demonstrate varoglutamstat has an excellent safety and tolerability profile, provide strong support for our understanding of the potential of QPCTL inhibitors in inflammatory and fibrotic diseases and lay the foundation for our strategic shift towards kidney disease based on the outstanding effect we observed on eGFR.”

H1 2024 and Post-Period Updates

Strategic shift towards a focus on inflammatory and fibrotic diseases

A significant positive effect of varoglutamstat on kidney function observed in the VIVIAD Phase 2b study in AD underpins the strategic shift to inflammatory and fibrotic diseases. In April 2024, Vivoryon announced this strategic shift following the announcement in March 2024 that the VIVIAD Phase 2b study did not achieve its primary and key secondary endpoints in early AD.

The VIVIAD protocol prospectively specified measurement of kidney function by estimated glomerular filtration rate (eGFR), a primary endpoint in many development programs of kidney disorders, and additional biomarkers, in order to further investigate this potential activity.

Key priorities now include:

• Preparing for a proposed Phase 2 clinical study for varoglutamstat in diabetic kidney disease (subject to additional funding and/or partnership);
• Concluding VIVIAD Phase 2b clinical study program and in-depth analysis;
• Analyzing the data of the VIVA-MIND Phase 2 clinical study with varoglutamstat in the U.S. in early AD by year end 2024;
• Continuing to actively pursue potential business development and financing opportunities.

Varoglutamstat Mechanism of Action

• Post-translational modification occurs both physiologically and in disease settings and it is a crucial process to functionalize proteins. Many different post-translational modifications are catalyzed by enzymes that have become known drug targets, e.g. kinases, proteases, or methylases.
• Pyroglutamate (pE) formation, a specific post-translational modification catalyzed by the glutaminyl cyclase enzymes QPCT and QPCTL, has emerged as a central element in different diseases including neurodegenerative, inflammatory and fibrotic diseases as well as cancer.
• Varoglutamstat is a highly potent oral small molecule inhibitor of human QPCT and QPCTL, designed to prevent inflammatory and fibrotic processes by blocking pyroglutamate formation on key disease drivers.
• QPCTL inhibition has demonstrated robust evidence of efficacy in animal models of inflammatory and fibrotic disorders such as glomerulonephritis and non-alcoholic steatohepatitis (NASH).

Varoglutamstat – VIVIAD kidney function results (total study population)

• Varoglutamstat 600mg BID increased eGFR over the treatment period up to 96 weeks in patients with early AD, indicating a potential benefit of varoglutamstat on kidney function. The treatment effect in the overall VIVIAD study population was 3.4mL/min/1.73m2/year (p<0.001; varoglutamstat n=141 / placebo n=117).
• Further sensitivity and subgroup analysis has shown this effect is observed across the range of eGFR levels at baseline in the study, and when assessed using a set of diverse and validated methods for calculating kidney function.
• Additionally, the Company has explored the effect of varoglutamstat on levels of pyroglu-CCL2 (pE-CCL2), a pro-inflammatory cytokine. Persistent, low grade inflammation is considered a hallmark feature of chronic kidney disease (CKD). Results showed a significant and dose-dependent reduction in pE-CCL2 in the serum of VIVIAD patients following treatment with varoglutamstat. This demonstrates the effectiveness of varoglutamstat in inhibiting systemic intracellular QPCTL and strongly supports an anti-inflammatory effect.

Significant effects of varoglutamstat in diabetes subgroup²

• Analysis of eGFR in a subgroup of patients with diabetes² in the VIVIAD Phase 2b study reveals a substantially higher treatment effect⁴ of >8mL/min/1.73m2/year (p=0.02; varoglutamstat n=20 / placebo n=12) compared to the overall VIVIAD study population where the treatment effect was 3.4mL/min/1.73m2/year (p<0.001; varoglutamstat n=141 / placebo n=117).
• Promising additional effects were observed in the diabetes subgroup in varoglutamstat treated patients including a reduction in liver transaminases, mild weight loss, and a reduction in diastolic blood pressure.
• Data revealed that the positive effect on kidney function in the diabetes subgroup appears to be independent of any change in glycemic control (HbA1C remained steady over the period for the varoglutamstat group).
• A reduction of the plasma concentration of the inflammatory and fibrosis inducing pE-CCL2 (p=0.004) was observed in the varoglutamstat arm, indicating a strong anti-inflammatory effect.
• Varoglutamstat was well-tolerated at the dose tested (up to 600mg twice daily) and there were no meaningful differences in adverse events observed in renal and metabolic system organ classes versus placebo or the total population.

Proposed Clinical Development Plan in Diabetic Kidney Disease (DKD)³

• Despite advances in the standard of care for DKD, there remains a significant unmet need for new therapies to stabilize kidney function and prevent disease progression.
• Vivoryon plans to start a Phase 2 study in DKD that is intended to include patients with disease stages more advanced than those observed in the VIVIAD Phase 2 study, enabling an expansion of the overall target patient population. The Company envisages a placebo-controlled study of up to approximately 120 subjects with stage 3b/4 DKD. These subjects would be randomized 1:1 to varoglutamstat 600mg twice daily or placebo, on top of standard of care medications. Key endpoints are planned to include eGFR slope analysis, measures of albuminuria (UA(p)CR), inflammation and fibrosis-related biomarkers, as well as safety.
• Vivoryon is evaluating business development and financing opportunities, to further explore the potential of varoglutamstat and QPCT/L inhibitors in kidney disease in both large indications, such as DKD, and in certain rare diseases that impact kidney function, such as Fabry disease and Alport Syndrome.

Varoglutamstat – early Alzheimer’s disease (AD)

• Vivoryon has continued its in-depth analysis of the VIVIAD data. Findings to date continue to confirm there is no consistent effect of varoglutamstat up to 600mg BID on cognition and function, including in high exposure patients. Results from pharmacokinetic, pharmacodynamic and biomarker data, including an assay for measuring pE-Abeta forms, suggests that intracellular QPCT may play a greater role in driving clinical outcomes in AD. Data from VIVA-MIND, anticipated by the end of 2024, is expected to contribute to the overall dataset informing varoglutamstat’s development strategy in AD.

Corporate Development Updates

• In March 2024, Kugan Sathiyanandarajah and Professor Dr. Morten Asser Karsdal stepped down from Vivoryon’s Board of Directors. They had been appointed as Non-Executive Directors in June 2023.
• In March 2024, Anne Doering, CFA, assumed the role of Chief Financial Officer (CFO) of Vivoryon, following her previous position as Chief Strategy & Investor Relations Officer.
• Vivoryon held its 2024 Annual General Meeting (AGM) on Friday, June 21, 2024, at 1:00 p.m. (CEST) in Amsterdam, the Netherlands. The shareholders approved all items on the agenda of the meeting. The full agenda and all relevant documents are available on the Company’s website (https://www.vivoryon.com/2024-annual-general-meeting/). Agenda items of particular note include the reappointment of Dr. Michael Schaeffer, Chief Business Officer, as executive director as well as the amendment to the Company’s articles of association with regard to, among other changes, the decrease of the nominal value of the shares in the capital of the Company to EUR 0.01 from EUR 1.00, which was implemented on September 5, 2024.

Financial Results for the First Half of 2024

Revenues were zero in the six months ended June 30, 2024, as well as in the six months ended June 30, 2023.

Research and development expenses increased by EUR 4.0 million to EUR 10.3 million in the six months ended June 30, 2024, compared to EUR 6.3 million in the six months ended June 30, 2023. This increase was largely attributable to the increase in clinical development costs from the VIVIAD and VIVA-MIND studies as well as early investments into kidney related research.

General and administrative expenses were EUR 3.5 million in the six months ended June 30, 2024, compared to EUR 4.4 million in the six months ended June 30, 2023. The decrease of EUR 0.9 million was largely attributable to higher non-executive board compensation in 2023.

Net loss for the six months ended June 30, 2024, was EUR 13.6 million, compared to EUR 10.7 million for the six months ended June 30, 2023.

The Company held EUR 15.3 million in cash and cash equivalents as of June 30, 2024, compared to EUR 28.6 million, which includes cash and cash equivalents and term deposits within financial assets, as of December 31, 2023. Cash utilization for the first six months of 2024 reflects the intensive investment period in VIVIAD and VIVA-MIND, both of which are expected to meaningfully ramp down in the second half 2024 as both studies approach their conclusion.

Outlook & Financial Guidance

As published on April 24, 2024, the Company expects, on the basis of its most recent financial and business plan, that its existing cash and cash equivalents will be sufficient to fund its operating plans, excluding any additional financings, into the second quarter of 2025.

This cash runway guidance reflects the shift in focus of research and development resources towards inflammatory and fibrotic disorders, such as of the kidney, and an overall reduction in cash utilization including the ramp down of spending on VIVIAD as it approaches its conclusion, the discontinuation of VIVA-MIND, the discontinuation of VIVALONG preparation activities given the developments of VIVIAD and VIVA-MIND, as well as the streamlining of manufacturing costs and programs for API development.

The viability of the Company beyond the second quarter of 2025 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.
