Vivoryon Therapeutics N.V. Provides Update on Growing Body of Evidence Validating Glutaminyl Cyclases as Promising Targets in DKD at World Congress of Nephrology

Halle (Saale) / Munich, Germany, March 28, 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 that new data analyses from the Company’s varoglutamstat Phase 2 program were presented at the World Congress of Nephrology (WCN) held in Yokohama, Japan, March 28-31, 2026.

“We are very pleased with the opportunity to share our consistently compelling results with world leading experts in the kidney space at WCN, the International Society of Nephrology’s flagship event,” said Frank Weber, MD, CEO of Vivoryon. “With these new analyses we are able to deliver additional mechanistic proof points showing that inhibition of glutaminyl cyclases can effectively address the underlying molecular changes in diabetic kidney disease. The data continue to strengthen our ongoing development program dedicated to making a meaningful contribution to shaping the future of global kidney care.”

Presentation Highlights
Vivoryon has thoroughly analyzed kidney function data from the two independent Phase 2 studies VIVIAD and VIVA-MIND, with highly consistent results between the two studies, highlighting the unique potential of varoglutamstat to meaningfully improve kidney function in patients with diabetes. The new analyses presented at WCN underscore previous reports showing that the effect of varoglutamstat on eGFR observed in both studies was greater in elderly participants with diabetes compared to elderly participants without diabetes. In participants with diabetes and lower baseline eGFR (mean 60 mL/min/1.73m²), the effect size was comparable or higher than in the total population of participants with diabetes. Additionally, analysis of data from a DKD mouse model showed significant improvements of inflammation, glomerulosclerosis and kidney function. Taken together, these results add to the growing body of evidence showing that inhibition of glutaminyl cyclases is valid approach to address the underlying inflammatory and fibrotic changes in DKD and support further development of varoglutamstat in patients with diabetes and more advanced CKD stages.
