Halle (Saale) / Munich, Germany, April 24, 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 twelve-month period ended December 31, 2023, and provided varoglutamstat and strategic updates including its pipeline development priorities and financial guidance.

“2023 was a year of clinical progress as we prepared for the readout from our VIVIAD Phase 2b study and advanced our U.S. study, VIVA-MIND, in early Alzheimer’s disease. We were very disappointed to report negative results from VIVIAD in March of this year, given the significant unmet need for new disease-modifying therapies. Our ongoing analysis of the topline data confirms that there was no consistent effect of varoglutamstat on cognition and function at the 600mg dose and we are continuing our in-depth analysis to uncover key learnings and inform our long-term strategy in AD. Varoglutamstat’s safety profile continues to look encouraging and we are excited to report today that we have observed a statistically significant improvement in kidney function based on pre-specified analysis of the estimated glomerular filtration rate measured in VIVIAD. This is in line with our prior hypothesis and results of pharmacological research on the role of the QPCT/L pathway beyond AD and is a very promising development. We are now prioritizing our resources and research and development activities to maximize value from varoglutamstat and our pipeline, with a focus on exploring its potential role in inflammatory and fibrotic diseases, including kidney disease, and determining additionally whether a path forward is viable in AD,” said Frank Weber, M.D., CEO of Vivoryon.

He continued, “Based on the VIVIAD analysis, and an assessment of funding needs, we have taken the decision, jointly with our principal investigator, to discontinue the VIVA-MIND study in early AD in the second half of 2024. This will enable us to accelerate analysis of patients treated in the study and explore varoglutamstat’s effect on certain endpoints including EEG theta power and kidney function and look for any trends in cognition. We hope the data from VIVA-MIND will increase our understanding of the role of QPCT/L inhibition in AD and evolve the science behind this devastating disease.”

In light of recent developments, the Company is today announcing prioritization of its resources into research and development activities it believes have the greatest potential to provide a meaningful impact for patients and for value creation. Key priorities reflect the strategic shift towards a focus on inflammatory and fibrotic diseases and include:

• Exploring varoglutamstat’s potential in inflammatory and fibrotic disorders, including of the kidney,
• Concluding VIVIAD Phase 2b clinical study program for varoglutamstat in Europe, including an in-depth analysis of the results presented on March 4, 2024, and further ongoing biomarker analysis,
• Discontinuing VIVA-MIND clinical Phase 2 study with varoglutamstat in the U.S. in the second half of 2024, earlier than planned, enabling accelerated analysis of the results which will contribute to the overall dataset informing varoglutamstat’s development strategy moving forward,
• Assessing the potential of varoglutamstat in doses higher than 600mg BID orally in early Alzheimer’s disease,
• Continuing to actively pursue potential business development and financing opportunities.

2023 and Post-Period Updates

Varoglutamstat Clinical Program:

VIVIAD study in early AD

VIVIAD (NCT04498650) is a state-of-the-art Phase 2b study conducted in Europe and designed to evaluate the safety, tolerability, and efficacy of varoglutamstat in 259 subjects with mild cognitive impairment (MCI) and mild Alzheimer’s disease (AD).

• In March 2024, Vivoryon announced topline data for VIVIAD. The study, which evaluated varoglutamstat up to 600mg BID, did not meet its primary endpoint of a statistically significant difference in cognitive improvement over time, assessed by the combined Z-score of the three elements of the Cogstate 3-item scale, as well as key secondary endpoints measuring cognition and function including the Cogstate Brief Battery (CBB); complete Cogstate neuropsychological test battery (NTB); the Amsterdam Instrumental Activities of Daily Living Questionnaire (A-IADL-Q) and electroencephalogram (EEG) global theta power.
• Safety results from the study showed that varoglutamstat was generally well tolerated and showed rates similar to placebo of serious and severe treatment emergent adverse events (TEAEs), low discontinuation rates due to adverse events and no evidence of symptomatic ARIAs (amyloid-related imaging abnormalities) in the clinical setting.
• Vivoryon is conducting an in-depth analysis of the VIVIAD data. While these analyses remain ongoing, findings to date confirm the topline results. Additionally, no statistically significant or clinically meaningful effect of varoglutamstat up to 600mg BID was observed on pre-specified subgroups. The only significant difference observed in favor of varoglutamstat was a lower change from baseline in the WAIS IV coding test and the letter fluency test, both measuring cognitive dysfunction, at week 48. Pharmacokinetic and QPCT/L enzyme inhibition data in VIVIAD were consistent with previous results.

VIVIAD study – results from kidney function exploratory analyses

• The VIVIAD protocol prospectively specified measurement of certain kidney function biomarkers. This was in line with the Company’s previously announced growth strategy to explore varoglutamstat’s potential effects on kidney function.
• Varoglutamstat 600mg BID increased the estimated glomerular filtration rate (eGFR) over the treatment period up to 96 weeks, indicating a potential benefit of varoglutamstat on kidney function. Analysis is ongoing including a closer analysis of VIVIAD results in patients with different eGFR levels at baseline.
• Given these statistically significant and clinically meaningful data, Vivoryon is evaluating a development path including business development and financing opportunities to further explore the potential of varoglutamstat and QPCT/L inhibitors in kidney disease.

VIVA-MIND study in early AD

VIVA-MIND (NCT03919162) is a Phase 2 study conducted in the U.S. evaluating the safety, tolerability, and efficacy of varoglutamstat in patients with early AD.

• Vivoryon announced today that, based on the ongoing review of VIVIAD data published March 4, 2024, and an assessment of funding needs, the Company has decided jointly with its principal investigator, to voluntarily discontinue the Phase 2 VIVA-MIND study in early AD in the U.S. in the second half of 2024. This will enable accelerated analysis of the results and will contribute to the overall dataset informing varoglutamstat’s development strategy moving forward. Initial data from the study is anticipated by the end of 2024.
• In October 2023, Vivoryon announced the study’s independent data and safety monitoring board (DSMB) recommended to continue VIVA-MIND with a 600mg BID dose throughout Phase 2a and 2b, which is an accelerated up-titration protocol compared to the VIVIAD Phase 2b study. This decision followed safety reviews and analyses of treatment-emergent adverse events of special interest (AESI) occurring in skin and subcutaneous tissue disorders and hepatobiliary disorders, target occupancy and pharmacokinetic (PK) data.

VIVALONG study

VIVALONG is an open-label extension (OLE) study offering a long-term treatment option to patients after completing VIVIAD or VIVA-MIND protocols.

• In line with the Company’s cost reduction measures and given the developments of VIVIAD and VIVA-MIND, Vivoryon has decided to stop VIVALONG OLE study preparation activities.

Early-Stage Pipeline

Vivoryon is revisiting the early-stage opportunities in its R&D activities in line with its strategic shift.

• Future pre-clinical activities will involve exploring QPCT/L inhibitors for use in inflammatory and fibrotic disorders as well as in other indications such as oncology and CNS.
• Opportunities with meprin inhibitors will continue to be explored, in particular for fibrotic disorders.
• The Company’s antibody program, PBD-C06, will remain active as a candidate for further potential partnering opportunities.
• The Company will continue to explore identification of second generation QPCT/L inhibitors with good blood brain barrier penetration.

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 previously 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.
• In October 2023, Vivoryon hosted a virtual R&D Event with Key Opinion Leaders (KOLs), focusing on varoglutamstat.
• In September 2023, Vivoryon held an Extraordinary General Meeting (EGM) related to the appointment of Frank Weber, MD, as CEO and Executive member of the Board of Directors. He followed Dr. Ulrich Dauer, former CEO of Vivoryon, after Dr. Dauer’s announcement in June 2023 to not renew his contract with the Company.
• In August 2023, Vivoryon and Scenic Biotech B.V. (“Scenic”) reached an agreement regarding the settlement of their patent dispute in connection with certain of Vivoryon´s patents related to varoglutamstat (PQ912) and certain other QPCT inhibitors. As part of the settlement, Scenic’s affiliate, Scenic Immunology B.V., and Vivoryon have entered into a patent license agreement, under which Scenic Immunology B.V. granted to Vivoryon certain rights to certain patents controlled by Scenic Immunology B.V. in the field of oncology.
• In May 2023, Vivoryon successfully raised EUR 25 million through an accelerated bookbuild offering. The private placement totaled 1,785,715 ordinary shares, at an issue price of EUR 14.00 per share.

Financial Results for the Full Year 2023

Revenues for the year ended December 31, 2023, reflected a EUR 3.6 million reversal in license revenue, compared to no revenue in the year ended December 31, 2022. The reversal is related to license revenues recognized in 2021 from a strategic regional licensing partnership with Simcere Pharmaceutical Group Ltd. (“Simcere”) to treat Alzheimer’s disease (AD) in Greater China, which includes a variable compensation for the first milestone. This variable milestone payment of EUR 3.6 million is based on the initiation of the first human clinical trial of varoglutamstat in mainland China. After the end of the reporting period the anticipated first milestone revenues were re-assessed. Due to the VIVIAD Phase 2b study not meeting its primary and key secondary endpoints, it is expected that the first human clinical trial in mainland China will not start before further clarity from an in-depth analysis of the VIVIAD results as well as from additional analysis of the full data and its implications. Therefore, revenues for the variable compensation (first development milestone) are no longer highly probable. As a consequence, the milestone-receivable of EUR 3.6 million was impaired and the respected revenues were reversed, as of December 31, 2023.

Research and development expenses decreased by EUR 2.6 million to EUR 17.6 million in the year ended December 31, 2023, compared to EUR 20.2 million in the year ended December 31, 2022. The decrease is primarily attributable to EUR 2.7 million lower third-party expenses, mainly due to EUR 3.6 million lower manufacturing costs, partially offset by EUR 1.7 million higher clinical costs, mainly due to the progress of the Phase 2b VIVIAD clinical study.

General and administrative expenses were EUR 8.6 million in the year ended December 31, 2023, compared to EUR 8.9 million in the year ended December 31, 2022. The decrease of EUR 0.3 million is largely attributable to the release of EUR 2.6 million of previously capitalized capital raising costs in 2022, partially offset by EUR 2.2 million higher expenses for personnel, legal and consulting, as well as costs for Non-Executive Directors. The reasons for the cost increases in personnel and for the Non-Executive Directors of the Board were predominantly caused by accelerated share-option expenses (EUR 0.3 million) and severance payments (EUR 0.6 million) as a result of the 2023 Board changes.

Net loss in the year ended December 31, 2023, was EUR 28.3 million, compared to EUR 28.2 million in the year ended December 31, 2022.

The Company held EUR 18.6 million in cash and cash equivalents as of December 31, 2023, plus term deposits of EUR 10.0 million disclosed under current financial assets, compared to cash and cash equivalents of EUR 26.6 million as of December 31, 2022.

Cash flows used in operating activities were EUR 21.5 million in the year ended December 31, 2023, compared to EUR 21.8 million in the year ended December 31, 2022.

Cash flows used in investing activities were EUR 10.5 million in the year ended December 31, 2023, compared to EUR 13 thousand in the year ended December 31, 2022. This difference reflects the net purchase of term deposits in the amount of EUR 10.0 million during 2023.

Cash flows provided from financing activities were EUR 24.2 million in the year ended December 31, 2023, compared to EUR 33.4 million in the year ended December 31, 2022.

Outlook & Financial Guidance

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 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. These activities also represent a change in focus of research and development resources towards inflammatory and fibrotic disorders, such as of the kidney, from an emphasis on Alzheimer’s disease.

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.

The financial statements have been prepared on the basis that the Company will continue as a going concern. The Company expects to have continuing operating losses for the foreseeable future and the need to raise additional capital to finance its future operations, and, as of April 24, 2024, the Company has concluded that the ability to continue as a going concern in the financial year 2025 depends on the ability to generate additional funding. Please refer to the Company’s Annual Report 2023 for further information.

Vivoryon will host a conference call and webcast today, April 24, 2024, at 3:00 pm CEST (9:00 am EDT). A Q&A session will follow the presentation of the full year results.
